591 (cursor_row_p): Call row_for_charpos_p with 2nd argument PT.
592 (row_containing_pos): Call row_for_charpos_p instead of partially
593 doing the same. Fixes cursor positioning under longlines-mode
594 when longlines-show-effect includes more than one newline, when

616 (entry_address, find_section, unexec): Use ptrdiff_t, not int,
617 when dealing with ElfW (Half) values, since they can exceed 2**31
618 on 64-bit OpenBSD hosts. Problem reported privately by Han Boetes.
619 (entry_address): Omit unused NUM arg. All uses changed.
621 2013-05-07 Juri Linkov <juri@jurta.org>

677 and dpyinfo->Xatom_net_current_desktop.
679 2013-05-06 Eli Zaretskii <eliz@gnu.org>
681 * xdisp.c (pos_visible_p): Use the special code for finding the
682 beginning of a display property or overlay for any "replacing"
683 display property, not just for display strings. This solves
684 incorrect reporting of position by posn-at-point. (Bug#14241)
686 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
688 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
689 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
690 Verify that ElfW (Half) fits in int.
691 (fatal): Use same signature as lisp.h.
692 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
693 configure and build with -DUNEXELF_DEBUG without worrying about
694 other modules that use DEBUG.
695 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
696 possibly-wide integers now uses it instead of plain fprintf.
697 (entry_address): New function, which avoids problems with 32-bit
698 overflow on 64-bit hosts.
699 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
700 (round_up): Don't assume the remainder fits in int.
701 (find_section): Use bool for boolean. Simplify debug code.
702 (unexec): Don't assume file sizes fit in int or size_t.
703 Omit unnecessary trailing newline in 'fatal' format.
704 Use strerror rather than outputting decimal error number.
705 Remove unused code when emacs is not defined;
706 this file relies on Emacs now.
707 Don't assume e_phnum and e_shnum are positive.
709 * regex.c: Fix problems when DEBUG is defined.
710 (extract_number, extract_number_and_incr): Define regardless of
711 whether DEBUG is defined; that's simpler and makes the code less
712 likely to go stale in the normal case when DEBUG is not defined.
713 Return int rather than taking an int * arg. All callers changed.
714 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
715 Remove, replacing with ...
716 (DEBUG_PRINT): New macro. All callers changed.
717 (DEBUG_COMPILES_ARGUMENTS): New macro.
718 (print_fastmap, print_partial_compiled_pattern) [DEBUG]:
719 (print_compiled_pattern, print_double_string) [DEBUG]:
720 Use prototype rather than old-style definition.
721 (print_partial_compiled_pattern, print_compiled_pattern) [DEBUG]:
722 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
723 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
724 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
725 Don't assume ptrdiff_t, size_t, and long are the same width as int.
726 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
727 This matters only when DEBUG is defined.
729 2013-05-05 Eli Zaretskii <eliz@gnu.org>
731 * xdisp.c (set_iterator_to_next): Set the
732 ignore_overlay_strings_at_pos_p flag only if we are _really_
733 iterating over an overlay string, as indicated by the
734 current.overlay_string_index member. (Bug#14306)
736 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
738 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
739 to where it is used, to avoid autorelease issues (Bug#14050).
741 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
743 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
744 * fileio.c (syms_of_fileio): Implement this.
745 * filelock.c (create_lock_file): If symbolic links don't work, so
746 we use a regular file as a lock file, do not fsync the lock file;
749 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
751 * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.

760 Use parentheses to disambiguate last part of the condition.
762 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
763 assertion violations. (Bug#14062)
765 2013-05-01 David Reitter <david.reitter@gmail.com>
767 * nsfns.m (ns_tooltip): Initialize.
769 2013-04-28 Eli Zaretskii <eliz@gnu.org>

772 a newline unless it's a CR character. (Bug#14287)
774 2013-04-28 Dan Nicolaescu <dann@gnu.org>
776 * dispextern.h (struct face): Move enum face_underline_type

786 2013-04-27 Juri Linkov <juri@jurta.org>
788 * callint.c (Fcall_interactively): Call `Qread_number' for
789 interactive code letter `n' instead of using duplicate code.
792 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
794 * systime.h (make_timeval): Declare as 'const'.
796 2013-04-27 Kenichi Handa <handa@gnu.org>
798 * font.c (font_open_entity): Always open a font of manageable
801 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
803 Port better to AIX (Bug#14258).
804 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,
807 2013-04-24 Kenichi Handa <handa@gnu.org>

810 sequence is encountered, reset the invocation and designation
811 status to the safest one.
813 2013-04-22 Paul Eggert <eggert@cs.ucla.edu>
815 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
816 Without this fix, "make distclean" leaves stamp-h1 behind.
818 2013-04-20 Erik Charlebois <erikcharlebois@gmail.com>
820 * w32fns.c (w32_fullscreen_rect): New function to compute the
821 window rectangle for the given fullscreen mode.
822 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
823 longer tunes the window size. This keeps the window's edges flush
824 with the screen and allows the taskbar to hide itself in fullboth.
826 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
827 window decorations and uses the entire screen.
829 * w32term.h (w32_fullscreen_rect) Add prototype.

849 * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
850 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
851 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
852 parentheses where appropriate.
854 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
856 * keyboard.c (timer_start_idle): Remove no-longer-used local.
858 2013-04-14 Eli Zaretskii <eliz@gnu.org>
860 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
861 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
862 Mention in the doc string that setting these variables takes
863 effect only after a call to set-window-buffer. (Bug#14200)
865 2013-04-13 Eli Zaretskii <eliz@gnu.org>
867 * indent.c (Fvertical_motion): Don't consider display strings on
868 overlay strings as display strings on the buffer position we
869 started from. This prevents vertical cursor motion from jumping
870 more than one line when there's an overlay string with a display
871 property at end of line.
872 Reported by Karl Chen <Karl.Chen@quarl.org> in
873 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

878 already selected (bug#14191).
880 2013-04-11 Eli Zaretskii <eliz@gnu.org>
882 * window.c (Fwindow_end): Test more flags, including the buffer's
883 last_overlay_modified flag, to determine whether the window's
884 display is really up-to-date. Prevents the function from
885 returning a stale value. (Bug#14170)
886 (Fwindow_line_height): Fix the test for up-to-date-ness of the
889 2013-04-10 Eli Zaretskii <eliz@gnu.org>
891 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
892 garbaged only if it is not already the top frame on its TTY.
893 This prevents flickering due to constant redrawing of TTY frames when
894 there are GUI frames open in the same session. (Bug#13864)
896 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
898 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
899 of marking the idle timers directly.

923 2013-03-31 Jan Djärv <jan.h.d@swipnet.se>
925 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
928 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
930 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
931 This bug was introduced by my 2013-02-25 change that simplified
932 data_start configuration. Without this change, on GNU/Linux
933 an Emacs configured with --enable-profiling fails immediately
934 due to a profiler signal.
935 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
936 with these flags. On platforms where special flags are needed
937 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
938 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
939 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
941 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>
943 Get rid of some platform-specific functions examining window
944 system and its capabilities. This is a partial rework of the

947 replaced with platform-independent window_system_available.
948 (check_window_system): Move to...
949 * frame.h (decode_window_system_frame, window_system_available):
950 ...here, add new prototypes.
951 * frame.c (window_system_available, decode_window_system_frame):
953 (check_window_system): Platform-independent now.
954 * xterm.h (x_in_use): Remove declaration.
956 * w32term.h (check_x_frame):
957 * nsterm.h (check_x_frame): Remove prototypes. This function
958 is replaced with platform-independent decode_window_system_frame.
959 * msdos.c (have_menus_p): Remove.
960 * nsfns.m (check_window_system, have_menus_p, check_ns_frame):
961 Remove platform-specific functions. Use check_window_system,
962 decode_window_system_frame and check_ns_display_info where
963 appropriate. Minor style and comment tweaks.

966 * xfns.c (x_in_use, check_window_system, have_menus_p, check_x_frame):
968 * fileio.c, fns.c, font.c, fontset.c, image.c, menu.c, nsmenu.m:
969 * nsselect.m, nsterm.m, w32font.c, w32menu.c, xfaces.c, xgselect.c:

981 (adjust_coding_eol_type): Do nothing if already adjusted.
982 (detect_coding): Compare the return value of check_ascii with
983 coding->src_bytes. Call adjust_coding_eol_type if necessary.
984 (decode_coding_gap): Optimize for valid UTF-8.
986 2013-03-21 Kenichi Handa <handa@gnu.org>
988 * coding.c (syms_of_coding): Cancel previous change.
990 * insdel.c (insert_from_gap): Fix previous change.

1013 Prefer < to > in range checks such as 0 <= i && i < N.
1014 This makes it easier to visualize quantities on a number line.
1015 This patch doesn't apply to all such range checks,
1016 only to the range checks affected by the 2013-03-24 change.
1017 This patch reverts most of the 2013-03-24 change.

1144 (redisplay_windows, redisplay_mode_lines, update_cursor_in_window_tree)
1145 (expose_window_tree): Likewise.
1146 Use contents slot, not buffer, where appropriate.
1147 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
1148 to avoid deleted windows. Use contents slot instead of buffer.
1149 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:

1423 to 1 (temporary workaround until a bug related to ASCII
1424 optimization is fixed).
1426 2013-03-19 Dmitry Antipov <dmantipov@yandex.ru>
1428 * window.c (Fwindow_combination_limit, Fset_window_combination_limit):
1429 Signal error if window is not internal. Adjust docstring.

1451 2013-03-17 Ken Brown <kbrown@cornell.edu>
1453 * dispextern.h (RGB_PIXEL_COLOR): Move here from image.c. Use it
1454 as return type of image_background. (Bug#13981)
1455 * image.c (RGB_PIXEL_COLOR): Move to dispextern.h.

1465 * nsfns.m (ns_filename_from_panel, ns_directory_from_panel):
1467 (Fns_read_file_name): ret is BOOL. If ! dir_only_p, don't choose
1468 directories. If filename is nil, get directory name (Bug#13932).
1469 Use getFilename and getDirectory.
1470 (getFilename, getDirectory): New methods for EmacsSavePanel and
1472 (ok:): In EmacsOpenPanel, if we can't choose directories, just return.

1484 * coding.h (struct coding_system): New member eol_seen.
1486 * coding.c (detect_ascii): New function.
1487 (detect_coding): Set coding->head_ascii and coding->eol_seen only
1488 when the source bytes are actually scanned. On detecting for
1489 coding_category_utf_8_auto, call detect_ascii instead of scanning
1490 source bytes directly.
1491 (produce_chars): Call insert_from_gap with the new arg 0.
1492 (encode_coding): Likewise.
1493 (decode_coding_gap): Control ASCII optimization by the variable

1516 * w32term.c (w32_read_socket) <WM_WINDOWPOSCHANGED>: Remove old
1517 and incorrect code. Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE
1519 (w32fullscreen_hook): If the frame is visible, reset
1520 f->want_fullscreen flag after changing the frame size. If the
1521 frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
1524 2013-03-13 Daniel Colascione <dancol@dancol.org>
1526 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
1527 too so that these builds can use Cygwin's file conversion
1528 functions. (We've been building and linking cygw32.o all along
1529 and just not using it.)
1531 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
1533 File synchronization fixes (Bug#13944).
1534 * Makefile.in (LIB_FDATASYNC): New macro.

1539 available if the system lacks one.
1540 (Fwrite_regin): Retry fsync if interrupted.
1542 2013-03-13 Eli Zaretskii <eliz@gnu.org>
1544 * w32term.c (w32_read_socket): If the Emacs frame is being
1545 activated, call w32fullscreen_hook, to make sure the new frame
1546 dimensions are in effect. (Bug#13937)
1548 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
1550 * xdisp.c (init_iterator): Simplify because both character and byte
1551 positions are either specified or -1. Add eassert. Adjust comment.
1552 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
1553 character and byte positions can be obtained from marker.
1555 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>

1570 a function pointer type; the C Standard requires this.
1572 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
1573 Include <sys/param.h> unconditionally, as that works elsewhere and
1574 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
1575 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
1578 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>
1580 * insdel.c (adjust_after_replace): Use bool for boolean.

1604 call ShellExecute in cygw32 builds.
1606 * w32fn.c (Fx_file_dialog): Use the above macros to simplify the
1607 common file dialog code.
1609 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
1610 can just use du like other systems.
1612 * coding.c (from_unicode_buffer): Declare.
1613 * coding.c (from_unicode_buffer): Implement.
1615 2013-03-10 Stefan Monnier <monnier@iro.umontreal.ca>

1661 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
1662 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
1663 from Elisp via unread-command-events.
1665 * keyboard.c (access_keymap_keyremap): Accept nil return value from
1666 functions to mean "no change".
1668 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1670 region-cache.c, scroll.c, search.c: Use bool for booleans.
1671 * lisp.h (compile_pattern):

1676 (search_regs_saved, Fregexp_quote):
1677 Use bool for boolean.
1678 * region-cache.c (region_cache_forward, region_cache_backward):
1679 Fix comments to match code: these functions return int, not boolean.
1681 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1683 * search.c (find_newline): Accept start and end byte positions
1684 as arguments and allow -1 if not known.
1685 (find_newline_no_quit): Likewise for start position.
1686 * lisp.h (find_newline, find_newline_no_quit): Adjust prototype.
1687 * bidi.c (bidi_find_paragraph_start): Pass byte position to
1688 find_newline_no_quit, thus eliminating CHAR_TO_BYTE.
1689 * editfns.c (Fconstrain_to_field): Break long line.
1690 Adjust call to find_newline.
1691 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

1695 (get_visually_first_element, move_it_vertically_backward): Likewise.
1696 Obtain byte position from the display iterator, where appropriate.
1698 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1700 print.c, process.c: Use bool for booleans.
1701 * lisp.h (wait_reading_process_output):
1702 * print.c (print_output_debug_flag, PRINTDECLARE, printchar)
1703 (strout, debug_output_compilation_hack, float_to_string, print)
1705 * process.c (kbd_is_on_hold, inhibit_sentinels, process_output_skip)

1716 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1718 * bidi.c (bidi_fetch_char): Swap first and second arguments
1719 to match other functions accepting character and byte positions.
1721 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.
1722 (bidi_paragraph_init): Likewise. Use DEC_BOTH which is faster
1723 when you need just to move to the previous buffer position.
1724 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1726 2013-03-07 Eli Zaretskii <eliz@gnu.org>
1728 * .gdbinit (prowlims): Display the enabled_p flag of the row.
1730 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>

1734 * indent.c (compute_motion): Use it and avoid CHAR_TO_BYTE.
1736 (Fcompute_motion): Break long line. Adjust call to compute_motion.
1737 Use list5 for return value.
1738 (vmotion): Use byte position argument and avoid call to CHAR_TO_BYTE.
1739 Adjust comments, style and calls to compute_motion.
1740 (Fvertical_motion): Adjust call to vmotion.
1741 * window.c (Fdelete_other_windows_internal): Record window start
1742 byte position and adjust call to vmotion.
1743 (window_scroll_line_based): Likewise with call to compute_motion.
1745 (Frecenter): Adjust calls to vmotion.
1747 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>
1749 * lisp.h (list2i, list3i): New functions.
1750 (list4i): Move from window.c and make LISP_INLINE.
1751 * editfns.c (make_lisp_time):
1752 * fns.c (Flocale_info):

1763 2013-03-06 Eli Zaretskii <eliz@gnu.org>
1765 * search.c (find_newline_no_quit): Rename from find_next_newline.
1768 * lisp.h (find_newline_no_quit): Rename prototype.

1795 (decode_coding, encode_coding): Add USE_SAFE_ALLOCA and SAFE_FREE.
1796 (decode_coding_object): Simplify since xrealloc never returns NULL.
1799 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
1801 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1802 * sysdep.c (list_system_processes)
1803 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1804 Make it a stub in this case; otherwise the build might fail,
1805 and this code hasn't been tested on such hosts anyway.
1806 Problem reported by Nelson H. F. Beebe in
1807 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1808 and analyzed by Jérémie Courrèges-Anglas in
1809 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1811 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1813 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1814 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1815 (get_visually_first_element, move_it_vertically_backward): Ajust users.
1816 * bidi.c (bidi_find_paragraph_start): Likewise.
1817 * indent.c (vmotion): Likewise.
1819 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1821 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1822 * filelock.c: Include <c-ctype.h>.
1823 (MAX_LFINFO): New top-level constant.
1824 (lock_info_type): Remove members pid, boot_time. Add members at,
1825 dot, colon. Change user member to be the entire buffer, not a
1826 pointer. This allows us to handle the case where a foreign
1827 pid or boot time exceeds the local range. All uses changed.
1828 (LINKS_MIGHT_NOT_WORK): New constant.
1829 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1830 (defined_WINDOWSNT): Remove.
1831 (MAKE_LOCK_NAME, file_in_lock_file_name):
1832 Always use .#FILE (not .#-FILE) for the file lock,
1833 even if it is a regular file.
1834 (rename_lock_file): New function.
1835 (create_lock_file): Use it.
1836 (create_lock_file, read_lock_data):
1837 Prefer a symbolic link for the lock file, falling back on a
1838 regular file if symlinks don't work. Do not try to create
1839 symlinks on MS-Windows, due to security hassles. Stick with
1840 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1841 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1842 host may be using a Windowsish file system, and cannot use
1843 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1844 doesn't work. Don't fail merely because of a symlink-contents
1845 length limit in the current file system; fall back on regular
1846 files. Increase the symlink contents length limit to 8 KiB, this
1847 should be big enough for any real use and doesn't crunch the
1849 (create_lock_file, lock_file_1, read_lock_data):
1850 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1851 (lock_file_1): Return error number, not bool. All callers changed.
1852 (ELOOP): New macro, if not already defined.
1853 (read_lock_data): Return size of lock file contents, not Lisp object.
1854 All callers changed. Handle a race condition if some other process
1855 replaces a regular-file lock with a symlink lock or vice versa,
1856 while we're trying to read the lock.
1857 (current_lock_owner): Parse contents more carefully, to help avoid
1858 confusing a regular-file lock with some other application's use
1859 of the file. Check for lock file contents being too long, or
1860 not parsing correctly.
1861 (current_lock_owner, lock_file):
1862 Allow foreign pid and boot times that exceed the local range.
1863 (current_lock_owner, lock_if_free, lock_file):
1864 Simplify allocation of lock file contents.
1865 * w32.c (sys_rename_replace): New function, containing most of
1866 the contents of the old sys_rename.
1867 (sys_rename): Use it.
1868 (fchmod): New dummy function.
1869 * w32.h (sys_rename_replace, fchmod): New decls.
1871 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1873 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1874 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1875 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1876 <dmantipov@yandex.ru>.
1878 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1880 * composite.c (get_composition_id, fill_gstring_header):
1881 Use make_uninit_vector where appropriate.
1882 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1883 * xselect.c (clean_local_selection_data): Likewise.
1885 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>

1888 * image.c (imagemagick_load_image): Calculate height and width
1889 after flattening the image, not before.
1891 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1893 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1894 * ftfont.c (ftfont_shape_by_flt): Likewise.
1895 * w32uniscribe.c (uniscribe_shape): Likewise.
1897 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1899 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1900 The old approach, which fell back on DIR/.#FILE.0 through
1901 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1902 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1903 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1904 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1905 because the locking mechanism was never reliable in that case).
1906 This patch fixes this and other bugs discovered by a code
1907 inspection that was prompted by
1908 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1909 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1910 to avoid interoperability problems between the MS-Windows and
1911 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1912 instances of Emacs now ignore each others' locks.
1913 * filelock.c (defined_WINDOWSNT): New constant.
1914 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1915 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1916 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1917 regular files on MS-Windows hosts.
1918 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1919 Use SAFE_ALLOCA to avoid problems with long file names.
1920 (MAX_LFINFO): Now a local constant, not a global macro.
1921 (IS_LOCK_FILE): Remove.
1922 (lock_file_1): Don't inspect errno if symlink call succeeds;
1923 that's not portable.
1924 (lock_file): Document that this function can return if lock
1926 (lock_file): Don't access freed storage.
1928 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

1932 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1934 * textprop.c: Use bool for booleans.
1935 (validate_interval_range, Fadd_text_properties)
1936 (Fremove_text_properties): Prefer bool to int when either works.
1938 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1940 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1941 If the interval tree changes as a side effect of calling
1942 modify_region, re-do processing starting from the call to
1943 validate_interval_range. (Bug#13743)
1945 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1947 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1950 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1952 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1953 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1954 access to the lock file until it is written and closed.

1967 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1969 Minor textprop integer cleanup.
1970 * intervals.h, textprop.c (add_text_properties_from_list):
1971 Return void, not int, since nobody uses the return value.
1972 * textprop.c (validate_plist, add_properties, remove_properties)
1973 (Fadd_text_properties):
1974 Don't assume list length fits in int.

1981 (Fremove_list_of_text_properties):
1982 Reindent do-while as per GNU style.

1986 Implement CLASH_DETECTION for MS-Windows.
1988 * filelock.c [WINDOWSNT]: Include w32.h.
1989 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1990 function of that name. Up-case the macro arguments.
1991 (IS_LOCK_FILE): New macro.
1992 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1993 (create_lock_file): New function, with body extracted from
1995 [WINDOWSNT]: Implement lock files by writing a regular file with
1996 the lock information as its contents.
1997 (read_lock_data): New function, on Posix platforms just calls
1999 [WINDOWSNT]: Read the lock info from the file.
2000 (current_lock_owner): Call read_lock_data instead of calling
2001 emacs_readlinkat directly.
2002 (lock_file) [WINDOWSNT]: Run the file name through
2005 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
2006 just check if the process by that PID exists.
2008 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
2009 also present, as doing so will fail to error out if the file
2012 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
2014 * textprop.c (Fadd_text_properties, Fremove_text_properties)
2015 (Fremove_list_of_text_properties): Skip all of the intervals in
2016 the region between START and END that already have resp. don't
2017 have the requested properties, not just the first one.
2018 Add assertions that the loop afterwards always modifies the
2019 properties. (Bug#13743)

2031 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
2032 (START_FILES): Remove. All uses removed.
2033 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
2034 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
2035 (buildobj.h): Use it.
2036 ($(ALLOBJS)): Depend on globals.h.

2049 * vm-limit.c: Move most of mem-limits.h's contents here.
2050 (data_start): New decl. It's OK if this is approximate,
2051 so simplify-away some unnecessary exactness.
2052 (POINTER): Remove; all uses removed.
2053 (data_space_start): Now char *, to avoid casts.
2054 (exceeds_lisp_ptr): New function, replacing the old
2055 EXCEEDS_LISP_PTR macro. All uses changed.
2056 (check_memory_limits): Simplify and remove casts.
2057 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

2070 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
2071 and diagnosed by Andreas Schwab in
2072 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
2074 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
2076 Assume C89 or better.
2077 * ralloc.c (SIZE, POINTER, NIL):
2078 * vm-limit.c (POINTER):
2079 Remove, replacing all uses with C89 equivalents. These old
2080 symbols were present only for porting to pre-C89 platforms.
2082 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
2084 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.

2100 2013-02-19 Daniel Colascione <dancol@dancol.org>
2102 * sheap.c (report_sheap_usage): Use message, not message1, so
2103 that we don't try to create a buffer while we're in the middle
2104 of dumping Emacs. Explain why.
2106 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
2108 * search.c (find_newline): Return byte position in bytepos.

2121 2013-02-19 Eli Zaretskii <eliz@gnu.org>
2123 * w32proc.c (new_child): Avoid leaking handles if the subprocess
2124 resources were not orderly released.
2126 2013-02-17 Eli Zaretskii <eliz@gnu.org>
2128 * xdisp.c (x_draw_vertical_border): For a window that is neither

2155 unconditionally. (Bug#9066)
2157 * w32.c (set_errno): Reset h_errno and don't set it to any other
2158 value. Set errno instead.
2159 (check_errno): Reset h_errno.

2171 2013-02-15 Eli Zaretskii <eliz@gnu.org>
2173 * keyboard.c (read_char): Fix calculation of auto-save time out
2174 when auto-save-timeout is less than 4. (Bug#13720)
2176 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

2183 make sure errno is set to an appropriate value. (Bug#13546)
2184 (socket_to_fd): Add assertion against indexing fd_info[] with a
2185 value that is out of bounds.
2186 (sys_accept): If fd is negative, do not set up the child_process
2187 structure for reading.
2189 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
2191 * composite.c (fill_gstring_header): Remove useless prototype.

2203 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
2205 Fix AIX port (Bug#13650).
2206 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
2207 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
2208 was #undeffed earlier, so it cannot be used as a macro here.
2209 Use the constant and not the macro.
2211 2013-02-15 Eli Zaretskii <eliz@gnu.org>
2213 * w32proc.c (new_child): If no vacant slots are found in
2214 child_procs[], make another pass looking for slots whose process
2215 has exited or died. (Bug#13546)
2217 * w32.c (sys_pipe): When failing due to file descriptors above
2218 MAXDESC, set errno to EMFILE.
2219 (_sys_read_ahead): Update cp->status when failing to read serial
2220 communications input, so that the status doesn't stay at
2221 STATUS_READ_IN_PROGRESS. (Bug#13546)
2223 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
2225 * gtkutil.c (tb_size_cb): New function.
2226 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
2228 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
2230 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
2233 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
2235 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
2237 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

2243 Break long line. Remove useless prototype and format comment.
2245 2013-02-13 Glenn Morris <rgm@gnu.org>
2247 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
2249 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2251 Improve AIX port some more (Bug#13650).
2252 With this, it should be as good as it was in 23.3, though it's
2253 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
2254 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
2255 * unexaix.c (start_of_text): Remove.
2256 (_data, _text): Declare as char[], not int, as AIX manual suggests.
2257 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
2258 (orig_load_scnptr, orig_data_scnptr):
2259 Now off_t, not long, since they are file offsets.
2260 (make_hdr): Use _data, not start_of_data ().
2261 This is the key part of the fix.
2262 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
2263 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
2265 * pre-crt0.c (data_start): Initialize to 1.
2266 This ports to compilers that optimize the external declaration
2267 'int x = 0;' as if it were 'int x;' to shrink the executable.
2269 Improve AIX port (Bug#13650).
2270 This doesn't fix the bug, but it makes progress: Emacs builds now.
2271 * unexaix.c: Include inttypes.h, stdarg.h.
2272 (report_error, report_error_1): Mark as _Noreturn.
2273 (report_error): Don't report the wrong errno.
2274 (report_error_1): Now varargs. All callers changed.
2275 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
2276 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
2277 (write_ptr): Use %p to print address rather than %lx and a cast
2278 to unsigned long. Grow buffer a bit, to be safer.
2280 2013-02-13 Eli Zaretskii <eliz@gnu.org>
2282 * bidi.c (bidi_resolve_neutral): After finding the next
2283 non-neutral character, accept NEUTRAL_ON type as well, because
2284 directional control characters, such as LRE and RLE, have their
2285 type converted to that by bidi_resolve_weak. This avoids aborts
2286 when LRE/RLE follows a run of neutrals.
2287 (bidi_move_to_visually_next): Assert that return value of
2288 bidi_peek_at_next_level is non-negative. Negative values will
2291 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2293 Minor getenv-related fixes.
2294 * callproc.c (Fcall_process_region) [!DOS_NT]:
2295 Avoid unnecessary duplicate call to getenv.
2296 * callproc.c (init_callproc):
2297 * dispnew.c (init_display):
2298 * sysdep.c (sys_subshell):
2299 Omit unnecessary cast of getenv or egetenv.
2301 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
2303 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
2304 Update dependencies.
2306 2013-02-12 Eli Zaretskii <eliz@gnu.org>
2308 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
2310 (display_line): Set w->region_showing to the value of
2311 it->region_beg_charpos, not to -1. This fixes redisplay
2312 optimization when cursor is moved up after M->. (Bug#13623)
2314 (try_scrolling): Scroll text up more if point is too close to ZV
2315 and inside the scroll margin. This makes sure point is moved
2316 outside the scroll margin in these cases.
2318 * window.h (struct window): region_showing can no longer be
2321 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
2323 Tune by using memchr and memrchr.
2324 * doc.c (Fsnarf_documentation):
2325 * fileio.c (Fsubstitute_in_file_name):
2326 * search.c (find_newline, scan_newline):
2327 * xdisp.c (pos_visible_p, display_count_lines):
2328 Use memchr and memrchr rather than scanning byte-by-byte.
2329 * search.c (find_newline): Rename from scan_buffer.
2330 Omit first arg TARGET, as it's always '\n'. All callers changed.
2332 Clean up read_key_sequence a tiny bit more.
2333 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
2334 (read_key_sequence): Remove unused locals.
2336 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
2338 Clean up read_key_sequence a bit; reread active keymaps after first event.
2339 * keyboard.c (read_char, read_char_x_menu_prompt)

2343 (active_maps): New function.
2344 (test_undefined): Also return true for nil bindings.
2345 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
2346 a single (composed) keymap. Remember `first_event' to choose the right
2347 set of active keymaps. Recompute the set of keymaps after receiving
2348 the first event. Remove GOBBLE_FIRST_EVENT.
2349 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
2350 * keyboard.h (read_char): Update declaration.
2351 * lread.c (read_filtered_event): Adjust call to read_char.

2370 2013-02-10 Eli Zaretskii <eliz@gnu.org>
2372 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2373 When text lines are longer than window's screen lines, don't move back
2374 too far. This speeds up some redisplay operations. (Bug#13675)
2376 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
2378 * syntax.c (scan_sexps_forward): Fix byte position calculation

2390 (sxhash_float): Return EMACS_UINT, for consistency with the other
2392 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
2393 non-static inline function and therefore can't use static vars.
2394 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
2395 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
2396 with the other hash functions.
2398 2013-02-09 Eli Zaretskii <eliz@gnu.org>
2400 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
2401 XXXXXX part of the temporary file pattern is not downcased even
2402 when w32-downcase-file-names is non-nil. (Bug#13661)
2404 * xdisp.c (decode_mode_spec): Remove handling of %t.
2406 * msdos.c (careadlinkatcwd): Remove.
2408 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
2410 * lread.c (skip_dyn_bytes): New function (bug#12598).

2483 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
2484 (syms_of_nsterm): Add ns-use-native-fullscreen.
2486 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
2488 * fileio.c (Qchoose_write_coding_system): Now static.
2490 2013-02-04 Eli Zaretskii <eliz@gnu.org>
2492 * xdisp.c (window_buffer_changed): region_showing can be negative,
2493 which still means region is being displayed.
2494 (redisplay_internal): Resurrect code that forced redisplay of the
2495 whole window when showing region and the mark has changed.
2496 Record the new mark position to allow redisplay optimizations.
2497 (display_line): If it->region_beg_charpos is non-zero, set the
2498 window's region_showing member to -1. (Bug#13623) (Bug#13626)

2501 not bitfield of 1 bit.
2503 2013-02-03 Daniel Colascione <dancol@dancol.org>
2505 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
2506 daemon mode works on cygw32 when Emacs is installed and not just
2509 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
2511 Avoid file time stamp bug on MS-Windows (Bug#13149).
2512 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
2513 as FAT32 doesn't update time stamps when truncating them.
2514 Also, check that a file time stamp is not a multiple of 100 ns;
2515 this should catch all instances of the problem on MS-Windows,
2516 as its native file system resolution is 100 ns or worse, and
2517 checking for a non-multiple of 100 ns should impose only a small
2518 overhead on systems with ns resolution.
2520 2013-02-02 Eli Zaretskii <eliz@gnu.org>
2522 Avoid encoding file names on MS-Windows when they need to be run
2523 through dostounix_filename.
2524 * w32.c (normalize_filename): Accept an additional argument
2525 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
2526 downcase it even if w32-downcase-file-names is non-nil.
2527 (dostounix_filename): Accept an additional argument MULTIBYTE and
2528 pass it to normalize_filename.
2529 (emacs_root_dir): Adjust.

2533 * w32.h (dostounix_filename): Adjust prototype.
2535 * msdos.c (dostounix_filename): Accept an additional argument and
2537 (init_environment): Adjust callers of dostounix_filename.
2539 * fileio.c (Ffile_name_directory, file_name_as_directory)
2540 (directory_file_name, Fexpand_file_name)
2541 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
2543 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
2545 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
2546 variables, as egetenv is case-insensitive for DOS_NT.
2548 * dired.c (file_name_completion): Don't call Fdirectory_file_name
2549 with an encoded file name.
2551 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
2552 Adjust calls to dostounix_filename.
2554 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
2556 * unexw32.c (unexec): Adjust call to dostounix_filename.
2558 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
2560 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
2563 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
2566 * callproc.c (Fcall_process): Make sure program name in PATH and
2567 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
2568 is passed to exec/spawnve, which fails unless the file-name
2571 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
2572 even if w32-quote-process-args is nil.
2574 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2576 Fix timestamp bug when write-region appends nothing (Bug#13149).
2577 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
2578 the file's time stamp doesn't change if Emacs happens to write nothing
2579 to the file, and on a buggy file system this could cause Emacs to
2580 incorrectly infer that the file system doesn't have the bug.
2581 Avoid this problem by inhibiting the inference in this case.
2583 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
2585 * window.h (struct window): Convert base_line_number, base_line_pos
2586 and column_number_displayed members from Lisp_Object to ptrdiff_t.

2596 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
2597 (try_scrolling, try_cursor_movement, redisplay_window)
2598 (try_window_reusing_current_matrix, try_window_id, display_line)
2599 (display_mode_lines, decode_mode_spec): Adjust users.
2600 * .gdbinit (pwinx): Do not print sequence_number.
2602 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2604 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
2605 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
2606 * dired.c: Include <fcntl.h>.
2607 (open_directory): New function, which uses open and fdopendir
2608 rather than opendir. DOS_NT platforms still use opendir, though.

2611 (directory_files_internal, Ffile_attributes): Use it.
2612 (file_attributes, file_name_completion_stat): First arg is now fd,
2613 not dir name. All uses changed. Use fstatat rather than lstat +
2615 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
2616 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
2617 (emacs_readlinkat): New function, with much of the old
2618 Ffile_symlink_p, but with an fd argument for speed.
2619 It uses readlinkat rather than careadlinkatcwd, so that it
2620 need not assume the working directory.
2621 (Ffile_symlink_p): Use it.
2622 * filelock.c (current_lock_owner): Use emacs_readlinkat
2623 rather than emacs_readlink.
2624 * lisp.h (emacs_readlinkat): New decl.
2625 (READLINK_BUFSIZE, emacs_readlink): Remove.
2626 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2627 (emacs_norealloc_allocator, emacs_readlink): Remove.
2628 This stuff is moved to fileio.c.
2629 * w32.c (fstatat, readlinkat): New functions.
2630 (careadlinkat): Don't check that fd == AT_FDCWD.

2647 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2648 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2651 * w32.c (w32_get_long_filename, init_environment, readlink):
2652 Support file names encoded in DBCS codepages.
2653 (readlink): Use the current file-name-coding-system, not the ANSI
2654 codepage, to decode and handle targets of symlinks.
2656 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2658 * w32.c (opendir): Now accepts a 'const char *'.

2672 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2674 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>

2677 debugging code. Adjust comment style here and there.
2678 * insdel.c (insert_1): Remove.
2679 * lisp.h (insert_1): Remove prototype.
2680 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2682 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2684 * w32.c (max_filename_mbslen): New function.
2685 (normalize_filename, readdir): Use it to detect locales where ANSI
2686 encoding of file names uses a double-byte character set (DBCS).
2687 If a DBCS encoding is used, advance by characters using
2688 CharNextExA, instead of incrementing a 'char *' pointer.
2689 Use _mbslwr instead of _strlwr. (Bug#13515)
2691 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial

2708 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2709 * frame.h (struct frame): Remove async_visible and async_iconified
2710 members, convert garbaged to unsigned bitfield. Adjust comments.

2730 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2732 * xdisp.c (message2, message2_nolog): Remove functions.
2733 (message3, message3_nolog): Extract nbytes and multibyteness directly
2734 from the string. Change all callers.
2735 (message3_nolog): Don't set message_enable_multibyte since set_message
2736 will reset it anyway.
2737 (message1, message1_nolog): Use message3.
2738 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2739 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2740 (set_message): Drop all but the second arg, which has to be a string.

2754 * editfns.c (message_text, message_length): Remove vars.
2755 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2756 * fileio.c (auto_save_error): Use message3 instead of message2.

2781 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2782 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2783 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2785 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2787 * xdisp.c (mark_window_display_accurate): Simplify the loop
2788 assuming that the only one of vchild, hchild or buffer window
2789 slots is non-nil. Call mark_window_display_accurate_1 for
2790 the leaf windows only.
2791 (mark_window_display_accurate_1): Always assume leaf window.
2794 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2796 * emacs.c (Qkill_emacs_hook): Now static.
2798 * fileio.c (Finsert_file_contents): Simplify.
2799 Remove unnecessary assignments and tests.
2801 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2803 * w32.c (acl_set_file): Don't test for errors unless
2804 set_file_security returns FALSE. Avoids spurious errors when
2807 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2809 * fileio.c (Finsert_file_contents): Revert code introduced at
2810 2013-01-18 in favor of the simpler and generally better fix.
2811 Save stack space by removing 'buffer' and reusing 'read_buf'
2814 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2816 * lisp.h (eabs): Define unconditionally (Bug#13419).
2817 The old "#if !defined (eabs)" was an unnecessary revenant of back
2818 when this macro was called "abs". Document 'eabs' better.
2820 2013-01-19 Glenn Morris <rgm@gnu.org>
2822 * fns.c (Frandom): Doc fix.
2824 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2826 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2827 segfault when there are lots of overlays.
2829 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2830 when there are lots of overlays.
2831 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2832 for the details and a way to reproduce.
2834 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2836 * fileio.c: Use O_APPEND to append.
2837 This corresponds better to the natural interpretation of "append",
2838 and avoids the need to open the output file twice, or to invoke
2839 lseek when APPEND is neither nil nor a number.
2840 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2841 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2842 file possibly twice, and lseeking to its end; this avoids the
2843 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2844 at the same time: the combination is never needed and apparently
2845 it doesn't work with DOS_NT.
2847 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2848 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2850 Allow floating-point file offsets.
2851 Problem reported by Vitalie Spinu in
2852 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2853 * fileio.c (emacs_lseek): Remove.
2854 (file_offset): New function.
2855 (Finsert_file_contents, Fwrite_region): Use it.
2857 2013-01-19 Chong Yidong <cyd@gnu.org>
2859 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2860 aborting on Fsignal (Bug#13289).
2862 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2864 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2865 set_file_security as failure due to insufficient privileges.
2866 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2867 (fstat): Return owner and group like 'stat' and 'lstat' do.
2869 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2871 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2872 The bug was observed on Ubuntu operating inside a virtual machine,
2873 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2874 The workaround introduces a race condition on non-buggy hosts,
2875 but it's an unlikely race and anyway there's a nearly identical
2876 nearby race that can't be fixed.
2877 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2879 (Fwrite_region): Test for file system time stamp bug.
2880 (init_fileio): New function.
2881 * lisp.h (init_fileio): Declare it.
2882 * emacs.c (main): Call it.
2884 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2885 and make it more consistent with other stat-failure diagnostics.
2887 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2889 Fix crash when inserting data from non-regular files.
2890 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2891 for the error description produced by valgrind.
2892 * fileio.c (read_non_regular): Rename to read_contents.
2893 Free Lisp_Save_Value object used to pass parameters.
2894 (read_non_regular_quit): Rename to read_contents_quit.
2895 (Finsert_file_contents): Redesign internal file reading loop to adjust
2896 gap and end positions after each read and so help make_gap to work
2897 properly. Do not signal an I/O error too early and so do not leave
2898 not yet decoded characters in a buffer, which was the reason of
2899 redisplay crash. Use list2 to build return value. Adjust comments.
2901 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2903 Close a race when statting and reading files (Bug#13149).
2904 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2905 This avoids a race if the file is renamed between stat and open.
2906 This race is not the problem originally noted in Bug#13149;
2907 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2909 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

2916 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2917 * alloc.c (format_save_value): Rename to make_save_value.
2918 (make_save_pointer): New function.
2919 (record_xmalloc): Use make_save_pointer.
2920 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2921 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2922 Change users of make_save_value to make_save_pointer.
2923 Likewise for format_save_value and make_save_value.

2934 * alloc.c (free_save_value): Now static.
2936 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2938 * keymap.c (map_keymap_internal): Use format_save_value.
2939 (map_keymap_char_table_item): Adjust accordingly.
2940 * fileio.c (non_regular_fd, non_regular_inserted)
2941 (non_regular_nbytes): Remove.
2942 (Finsert_file_contents): Convert trytry to ptrdiff_t.
2943 Use format_save_value to pass parameters to read_non_regular.
2944 (read_non_regular): Use XSAVE_ macros to extract parameters.
2946 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
2948 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
2950 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2952 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2953 extraction from any Lisp_Save_Value slot. Add type checking.
2954 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
2955 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
2956 * xselect.c: All users changed.
2958 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

2963 (format_save_value): New prototype.
2964 * alloc.c (allocate_misc): Revert back to static.
2965 (format_save_value): New function to build Lisp_Save_Value
2966 object with the specified internal structure.
2967 (make_save_value): Reimplement using format_save_value.
2968 * editfns.c (save_excursion_save): Use format_save_value.
2969 (save_excursion_restore): Use XSAVE_OBJECT.
2971 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
2973 Avoid needless casts with XSAVE_POINTER.
2974 * alloc.c (mark_object) [GC_MARK_STACK]:
2975 * dired.c (directory_files_internal_unwind):
2976 * fileio.c (do_auto_save_unwind):
2977 * gtkutil.c (pop_down_dialog):
2978 * keymap.c (map_keymap_char_table_item):
2979 * lread.c (load_unwind):
2980 * nsmenu.m (pop_down_menu):
2981 * print.c (print_object) [GC_MARK_STACK]:
2982 * xfns.c (clean_up_file_dialog):
2983 * xmenu.c (cleanup_widget_value_tree):
2984 Omit casts between XSAVE_POINTER and a pointer type.
2986 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2988 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
2989 * eval.c (eval_sub): Protect `form' from being GCed before its
2990 car and cdr becomes protected with the backtrace entry.
2992 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2994 Make Lisp_Save_Value more versatile storage for up to four objects.

3004 (free_save_value): Likewise.
3005 (mark_object): Likewise.
3006 * editfns.c (save_excursion_save): Pack everything within
3007 Lisp_Save_Value and so avoid xmalloc.
3008 (save_excursion_restore): Adjust to match new layout. Use free_misc
3009 because we do not allocate extra memory any more. Add eassert.
3010 * print.c (print_object): New code to print Lisp_Save_Value. Do not
3011 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
3012 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
3013 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

3019 (nsfont_draw): Remove disabling of LCD smoothing.
3020 (ns_glyph_metrics): Add LCD_SMOOTHING_MARGIN to bearings to fix
3021 Bug#11484 with LCD smoothing on.
3023 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
3025 Fix SIGDANGER handlers, for AIX (Bug#13408).
3026 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
3027 Move handlers here from emacs.c; they were out of place.
3029 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
3031 * xterm.c (syms_of_xterm): Adjust documentation for
3032 scroll-bar-adjust-thumb-portion.

3052 (nsfont_open): Move block_input earlier. Add unblock_input before early
3054 (nsfont_draw): Add block/unblock_input calls.
3056 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
3058 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
3059 for old_charpos and old_bytepos.

3063 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
3064 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
3065 Clear tzvalbuf_in_environ if this workaround is in effect.
3066 Problem and fix reported by Kazuhiro Ito.

3077 string cross-reference(s).
3079 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
3081 Avoid unnecessary byte position calculation for the gap movement.
3082 Since all users of move_gap do CHAR_TO_BYTE for other purposes
3083 anyway, all of them should use move_gap_both instead.
3084 * lisp.h (move_gap): Remove prototype.
3085 * insdel.c (move_gap): Remove.
3086 (move_gap_both): Add eassert.

3095 * term.c (init_tty): Use them instead of rolling our own code.
3096 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
3097 switches from 'signal' to 'pthread_sigmask', which is safer in
3098 multithreaded applications.
3099 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
3100 which has already arranged for that.
3101 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
3102 This is the main part of the bug fix.

3111 Omit buffer_slot_type_mismatch and use generic predicates to enforce
3112 the type of per-buffer values where appropriate.
3113 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
3114 predicate, which is how it's really used now. Adjust comment.
3115 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
3116 * buffer.c (buffer_slot_type_mismatch): Remove.
3117 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

3122 right-fringe-width, scroll-bar-width and buffer-display-count.
3123 Use Qstringp for default-directory, buffer-file-name,
3124 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
3125 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
3127 * data.c (store_symval_forwarding): Adjust to call the predicate.
3129 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
3131 * w32.c (get_name_and_id, acl_set_file):
3132 * w32term.c (w32fullscreen_hook): Remove unused local variables.

3144 (make_gap_1): New function to adjust the gap of any buffer.
3145 * coding.c (coding_alloc_by_making_gap): Use it.
3146 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
3147 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.

3170 trailing dash is properly added.
3172 2013-01-05 Eli Zaretskii <eliz@gnu.org>
3174 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
3175 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
3176 digits for buffer positions, before misalignment starts.
3177 Display "0" for integer "object" field.
3178 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
3179 Display the newline glyph more unambiguously.

3189 * w32term.c (x_draw_glyph_string):
3190 * xterm.c (x_draw_glyph_string): Don't use previous underline
3191 thickness and position if previous underline type is underwave.

3238 Check toolbar_is_packed.
3239 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
3240 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3241 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
3243 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3244 (xg_update_menubar): Update title only if
3245 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3246 (xg_update_submenu): Skip tearoff only if
3247 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3248 (xg_initialize): Initialize xg_detached_menus only if
3249 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
3251 * xterm.h (struct x_output): Surround handlebox_widget with
3252 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
3253 toolbar_in_hbox is bool.
3255 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
3257 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
3258 (LIBS_GNUSTEP): Define.
3259 (LIBES): Add $(LIBS_GNUSTEP).
3260 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
3262 2012-12-30 Eli Zaretskii <eliz@gnu.org>
3264 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
3265 continuation glyph on a TTY with an indication of an empty line.
3268 2012-12-29 Eli Zaretskii <eliz@gnu.org>
3270 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
3271 file's SELinux context or ACLs successfully set, nil otherwise.
3273 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
3275 * w32proc.c (reader_thread): Avoid passing NULL handles to
3276 SetEvent and WaitForSingleObject.
3278 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
3280 Port EXTERNALLY_VISIBLE to Clang 3.2.
3281 * conf_post.h (__has_attribute): New macro.
3282 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
3284 2012-12-27 Glenn Morris <rgm@gnu.org>
3286 * cygw32.c (Fcygwin_convert_file_name_to_windows)
3287 (Fcygwin_convert_file_name_from_windows): Doc fixes.
3289 2012-12-27 Eli Zaretskii <eliz@gnu.org>
3291 * fileio.c (file_name_as_directory, directory_file_name):
3292 Accept an additional argument MULTIBYTE to indicate whether the input C
3293 came from a multibyte or a unibyte Lisp string; all callers
3294 adjusted. Don't assume the input string is always multibyte.
3296 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
3297 don't ENCODE_FILE them, and return a unibyte string if the input
3299 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
3300 don't assume the input strings will always be multibyte. If the
3301 input strings are multibyte, decode strings obtained from C
3304 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
3306 * lisp.h (toplevel): Add two notices to the comment about
3307 defining a new Lisp data type.
3308 * print.c (print_object): If Lisp_Save_Value object's pointer
3309 is the address of a memory area containing Lisp_Objects, try
3311 * alloc.c (valid_lisp_object_p): Adjust comment.
3313 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
3315 * keyboard.c (record_asynch_buffer_change): Initialize an event
3316 only if it's really needed.
3317 * frame.h (enum output_method): Remove output_mac member since
3318 it's a leftover from the deleted code.
3319 * frame.c (Fframep): Adjust user here ...
3320 * terminal.c (Fterminal_live_p): ... and here.
3321 * coding.c (Qmac): Now here because it's only used to denote
3322 end-of-line encoding type.
3323 (syms_of_coding): DEFSYM it.
3324 * frame.h (Qmac): Remove duplicated declaration.
3326 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
3328 * window.c (select_window_1): Now static, since it's used only here.
3330 2012-12-25 Eli Zaretskii <eliz@gnu.org>
3332 * window.c (window_body_cols): Subtract display margins from the
3333 window body width on TTYs as well. See
3334 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
3335 for the original report.
3337 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
3339 * xdisp.c (redisplay_window): Remove inner local variable
3340 because the outer shadowed one has the same meaning.
3341 * xterm.h (struct x_output): Remove toolbar_detached member since it's
3343 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
3344 (xg_create_tool_bar): Adjust users.
3346 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
3348 * buffer.h (BUF_COMPACT): New macro to follow the common style.
3349 * buffer.c (Fget_buffer_create): Use it to set compact field of
3350 struct buffer_text to avoid accessing an uninitialized value
3351 when compact_buffer is called for the first time.
3352 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
3353 (Fset_buffer_modified_p): Use buffer_window_count to check
3354 whether the buffer is displayed in some window.
3355 * xdisp.c (message_dolog): Likewise.
3357 2012-12-23 Eli Zaretskii <eliz@gnu.org>
3359 * w32.c (acl_set_file): If setting the file security descriptor
3360 fails, and the new DACL is identical to the existing one, silently
3361 return success. This fixes problems for users backing up their
3362 own files without having the necessary privileges for setting
3363 security descriptors.
3365 * w32proc.c (reader_thread): Do not index fd_info[] with negative
3367 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
3368 after WaitForSingleObject returns normally. This expedites reader
3369 thread shutdown when delete_child triggers it.
3370 (reap_subprocess): More accurate commentary for why we call
3371 delete_child only when cp->fd is negative.
3373 * w32.c (sys_close): Do not call delete_child on a subprocess
3374 whose handle is not yet closed. Instead, set its file descriptor
3375 to a negative value, so that reap_subprocess will call
3376 delete_child on that subprocess when its SIGCHLD arrives.
3377 This avoids closing handles used for communications between sys_select
3378 and reader_thread, which doesn't give sys_select a chance to
3379 notice that the process exited and invoke the SIGCHLD handler for
3382 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
3384 * nsfns.m (Fns_do_applescript): Run event loop until script has
3385 been executed (Bug#12969).
3386 (ns_run_ascript): Chech as_script for nil, set to nil after
3389 2012-12-22 Martin Rudalics <rudalics@gmx.at>
3391 * window.c (Fselect_window): Reword doc-string (Bug#13248).
3393 2012-12-22 Eli Zaretskii <eliz@gnu.org>
3395 * w32term.c (w32fullscreen_hook): New function.
3396 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
3398 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3400 * fileio.c (Finsert_file_contents): Doc fix.
3402 * w32proc.c (new_child, delete_child, find_child_pid): For a
3403 subprocess, consider its slot being in use as long as its process
3404 handle (procinfo.hProcess) is not NULL. This avoids reusing the
3405 slot when a new process is started immediately after killing
3406 another one, without waiting enough time for the first process to
3407 be reaped and resources allocated for it be orderly freed.
3409 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
3411 2012-12-21 Chong Yidong <cyd@gnu.org>
3413 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
3415 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
3417 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3419 * w32.c (get_name_and_id): Always pass NULL as the first argument
3420 of lookup_account_sid. Avoids crashes with UNC file names that
3421 refer to DFS domains, not to specific machine names. (Bug#12621)
3422 Remove now unused argument FNAME; all callers changed.
3423 (get_file_owner_and_group): Remove now unused argument FNAME; all
3426 2012-12-21 Chong Yidong <cyd@gnu.org>
3428 * editfns.c (Finsert_char): Since read-char-by-name now signals an
3429 error for invalid chars, don't check for a nil return value.
3431 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3433 Avoid calls to CHAR_TO_BYTE if byte position is known.
3434 * editfns.c (make_buffer_string_both): Use move_gap_both.
3435 (Fbuffer_string): Use make_buffer_string_both.
3436 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
3438 (buf_bytepos_to_charpos): Likewise.
3439 (charpos_to_bytepos): Remove.
3440 * fileio.c (Finsert_file_contents): Use move_gap_both.
3441 * search.c (Freplace_match): Likewise.
3442 * process.c (process_send_region): Likewise. Use convenient
3443 names for byte positions.
3444 * lisp.h (charpos_to_bytepos): Remove prototype.
3445 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
3446 * insdel.c (move_gap): Likewise.
3448 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
3450 * xdisp.c (redisplay_internal): Remove now-unused local.
3452 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
3454 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
3455 (redisplay_internal): Don't bother selecting the frame to get the
3456 proper value of frame-local variables (bug#13225).
3458 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3460 * textprop.c (set_text_properties_1): Do not allow NULL interval.
3461 Rename 4th argument since it may be buffer or string. Adjust comment.
3462 * intervals.c (graft_intervals_info_buffer): Find an interval here.
3464 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
3466 * coding.c (Fdetect_coding_region): Do not check start and end with
3467 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
3468 (code_convert_region): Likewise.
3470 2012-12-18 Eli Zaretskii <eliz@gnu.org>
3472 * w32.c (acl_get_file, acl_set_file): Run the file name through
3473 map_w32_filename, and resolve any symlinks in the file name, like
3475 (acl_set_file): Call revert_to_self, if any privileges were
3478 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
3480 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
3481 ($(BLD)/w32.$(O)): Update dependencies.
3483 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
3485 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
3486 propagate redisplay's scrolling (if any) to the right window.
3487 (redisplay_internal): Use ensure_selected_frame.
3488 (display_mode_lines): Complete last fix.
3489 * window.c (select_window_1): New func, extracted from select_window.
3490 (select_window): Use it.
3491 * window.h (select_window_1): Declare.
3493 2012-12-17 Eli Zaretskii <eliz@gnu.org>
3495 Emulate Posix ACL APIs on MS-Windows.
3496 * w32.c: Include sddl.h and sys/acl.h.
3497 (SDDL_REVISION_1): Define if not already defined.
3498 (g_b_init_get_security_descriptor_dacl)
3499 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
3500 (g_b_init_is_valid_security_descriptor)

3513 (acl_free, acl_get_file, acl_set_file): New functions.
3515 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
3517 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
3519 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
3520 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
3521 for some of that bug's symptoms can now cause Emacs to abort.
3522 Remove the workaround.
3523 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
3524 The bug that caused SIGCHLD to get lost has been fixed, and the
3525 workaround for it can now cause Emacs to abort.
3527 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
3529 * sysdep.c (emacs_abort): Bump backtrace size to 40.
3530 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
3531 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
3533 2012-12-16 Romain Francoise <romain@orebokech.com>
3535 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
3536 (Fcopy_file): Change last arg to `preserve_extended_attributes'
3537 and copy ACL entries of file in addition to SELinux context if set.
3538 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
3540 * Makefile.in (LIBACL_LIBS): New macro.
3543 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
3545 * fileio.c (internal_delete_file): Use bool for boolean.

3553 (record_infile, record_pending_deletion): New prototypes.
3555 * w32proc.c (new_child): Initialize input_file and
3556 pending_deletion members of the child.
3557 (delete_child): Delete the child's temporary input file, if any,
3558 that is pending deletion.
3559 (register_child): First argument is now pid_t.
3560 (record_infile, record_pending_deletion): New functions.
3561 (reap_subprocess): Fix a typo in DebPrint string.
3562 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
3564 * fileio.c (internal_delete_file): Return an int again: non-zero
3565 if delete-file succeeds, zero otherwise.
3567 * lisp.h (internal_delete_file): Adjust prototype.
3569 * callproc.c (Fcall_process): Don't overwrite infile with result
3571 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
3572 asynchronous subprocess, record the name of the input file name,
3574 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
3575 delete the file, record it as pending deletion when the subprocess
3578 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3580 * editfns.c [HAVE_PWD_H]: Include grp.h.
3582 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
3584 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
3586 Fix permissions bugs with setgid directories etc. (Bug#13125)
3587 * dired.c (Ffile_attributes): Return t as the 9th attribute,
3588 to mark it as a placeholder. The old value was often wrong.
3589 The only user of this attribute has been changed to use
3590 file-ownership-preserved-p instead, with its new group arg.
3591 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
3593 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

3598 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3600 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
3601 try to get accurate owner and group information from NT file
3602 security APIs. This is to make most callers of 'stat' and
3603 'lstat', which don't need that information, much faster.
3605 * dired.c (Ffile_attributes) [WINDOWSNT]:
3606 Set w32_stat_get_owner_group to a non-zero value, to request accurate
3607 owner and group information from 'lstat'.
3609 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3611 * fileio.c (Finsert_file_contents): Don't put tail into head area,
3612 as that confuses set-auto-coding, so insist on the head-read
3613 returning the full 1024 bytes. Let lseek compute the tail offset;
3614 less work for us. Do not ignore I/O errors when reading the tail.
3616 * xdisp.c: Minor style fixes.
3617 (init_iterator): Hoist assignment out of if-expression.
3618 (markpos_of_region): Callers now test for sign, not for -1.
3620 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
3622 Minor redisplay optimization when the region length is zero.
3623 * xdisp.c (markpos_of_region): New function.
3624 (init_iterator): Do not highlight the region of zero length.
3625 (redisplay_window): Check whether the region is of non-zero length.
3626 (try_cursor_movement): Allow if the region length is zero.
3627 (try_window_reusing_current_matrix, try_window_id): Likewise.
3629 2012-12-13 Eli Zaretskii <eliz@gnu.org>
3631 * search.c (search_buffer): Check the inverse translations of each
3632 character in pattern when the buffer being searched is unibyte.
3635 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3637 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
3638 files, fixing a regression from 24.2.
3639 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
3641 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3643 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
3644 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3645 Remove unnecessary S_ISLNK test, as (contra the comments) this
3646 function can't copy symlinks. Improve quality of error message
3647 when attempting to copy files that are neither regular files nor

3654 * window.c (Frecenter):
3655 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
3656 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
3658 2012-12-12 Daniel Colascione <dancol@dancol.org>
3660 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
3661 the dumped Emacs is not a sparse file, greatly improving Cygwin
3662 "make bootstrap" performance.
3664 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
3666 * inotify.c (inotify_callback): Generate an Emacs event for every
3667 incoming inotify event.
3669 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3671 * xdisp.c (handle_face_prop): Fix logic of computing
3672 it->start_of_box_run_p.
3673 (append_space_for_newline): If the glyph row is R2L, reset the
3674 iterator's end_of_box_run_p flag before prepending the space glyph.
3675 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
3676 iterator's start_of_box_run_p flag before prepending the stretch.
3677 (append_glyph, produce_image_glyph, append_composite_glyph)
3678 (append_stretch_glyph, append_glyphless_glyph): Reverse the
3679 left_box_line_p and right_box_line_p flags of the glyph for R2L
3680 glyph rows. (Bug#13011)
3682 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
3684 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
3685 if changed buffer is not shown in a window.
3686 * insdel.c (prepare_to_modify_buffer): Likewise.
3687 * window.c (replace_buffer_in_windows_safely): Do nothing
3688 if buffer is not shown in a window.

3692 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3694 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
3695 encoded_file_name, which is what it is.
3697 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
3699 Consistently use marker_position and marker_byte_position.

3880 * dbusbind.c (Fdbus_init_bus):
3882 * xterm.c (x_term_init):

3893 no longer needed here.
3894 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
3895 Move to inside set_time_zone_rule; they don't need file scope any more.
3896 (set_time_zone_rule): Maintain the TZ=value string separately.
3897 (syms_of_editfns): Don't initialize initial_tz;
3898 init_editfns now does it.
3899 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
3900 * lisp.h (xputenv): New decl.
3902 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
3904 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
3906 2012-12-08 Eli Zaretskii <eliz@gnu.org>
3908 * w32.c (unsetenv, sys_putenv): New functions.

3913 informative (Bug#12992).
3915 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3917 Simplify get_lim_data.
3918 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3919 Remove USG and vlimit methods; no longer used these days.
3920 Add #error catchall just in case.
3922 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3923 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3924 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
3925 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
3926 (deleted_pid_list, Fdelete_process, create_process)
3927 (record_child_status_change, handle_child_signal, deliver_child_signal)

3931 (abbr_to_signal): New static function.
3932 (Fsignal_process): Use it to convert signal names to ints.

3943 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
3945 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
3946 This will cause a production Emacs to dump core instead of
3949 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3951 * frame.c (make_frame): Do not set window's buffer to t.
3952 * window.c (Fsplit_window_internal): Likewise. Previously it was
3953 used to indicate that the window is being set up. Now we use
3954 set_window_buffer for all new windows, so the condition in ...
3955 (Fset_window_buffer): ... is always true and can be removed.
3957 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3959 Convenient macro to check whether the buffer is hidden.
3960 * buffer.h (BUFFER_HIDDEN_P): New macro.
3961 * frame.c (make_frame): Use it. Adjust comment.
3962 * buffer.c (candidate_buffer): New function.
3963 (Fother_buffer, other_buffer_safely): Use it.
3965 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3967 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
3968 if the child process is still running. Instead, exit the wait
3969 loop and return zero. (Bug#13086)
3971 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3973 * frame.h (x_char_width, x_char_height): Remove prototypes.

3987 * callproc.c, process.h (record_kill_process):
3988 New function, containing part of the old call_process_kill.
3989 (call_process_kill): Use it.
3990 This does not change call_process_kill's behavior.
3991 * process.c (Fdelete_process): Use record_kill_process to fix a
3992 race condition that could cause Emacs to lose track of a child.
3994 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3996 Avoid code duplication between prev_frame and next_frame.
3997 * frame.c (candidate_frame): New function. Add comment.
3998 (prev_frame, next_frame): Use it. Adjust comment.
4000 2012-12-06 Eli Zaretskii <eliz@gnu.org>
4002 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
4003 fails, signal an error instead of continuing with an empty
4005 Encode expanded temp file pattern before passing it to mkstemp or
4008 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
4009 Encode the file name before passing it to dostounix_filename, in
4010 case it will downcase it (under w32-downcase-file-names).
4013 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
4015 Minor call-process cleanups.
4016 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
4017 at the same time as other platforms, to simplify analysis.
4018 No need for fd0_volatile since we have synch_process_fd.
4019 Avoid needless emacs_close; arg is always negative.
4021 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
4023 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
4026 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
4028 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
4029 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer

4034 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
4035 member. Adjust users. Convert term_initted, delete_in_insert_mode,
4036 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
4037 members to a bitfields.
4039 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
4041 Don't let call-process be a zombie factory (Bug#12980).
4042 Fixing this bug required some cleanup of the signal-handling code.
4043 As a side effect, this change also fixes a longstanding rare race
4044 condition whereby Emacs could mistakenly kill unrelated processes,
4045 and it fixes a bug where a second C-g does not kill a recalcitrant
4046 synchronous process in GNU/Linux and similar platforms.
4047 The patch should also fix the last vestiges of Bug#9488,
4048 a bug which has mostly been fixed on the trunk by other changes.
4049 * callproc.c, process.h (synch_process_alive, synch_process_death)
4050 (synch_process_termsig, sync_process_retcode):
4051 Remove. All uses removed, to simplify analysis and so that
4052 less consing is done inside critical sections.
4053 * callproc.c (call_process_exited): Remove. All uses replaced
4054 with !synch_process_pid.
4055 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
4056 These take the role of what used to be in unwind-protect arg.
4058 (block_child_signal, unblock_child_signal):
4059 New functions, to avoid races that could kill innocent-victim processes.
4060 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
4061 (call_process_kill): Record killed processes as deleted, so that
4062 zombies do not clutter up the system. Do this inside a critical
4063 section, to avoid a race that would allow the clutter.
4064 (call_process_cleanup): Fix code so that the second C-g works again
4065 on common platforms such as GNU/Linux.
4066 (Fcall_process): Create the child process in a critical section,
4067 to fix a race condition. If creating an asynchronous process,
4068 record it as deleted so that zombies do not clutter up the system.
4069 Do unwind-protect for WINDOWSNT too, as that's simpler in the
4070 light of these changes. Omit unnecessary call to emacs_close
4071 before failure, as the unwind-protect code does that.
4072 * callproc.c (call_process_cleanup):
4073 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
4074 * process.c (record_deleted_pid): New function, containing
4075 code refactored out of Fdelete_process.
4076 (Fdelete_process): Use it.
4077 (process_status_retrieved): Remove. All callers changed to use
4078 child_status_change.
4079 (record_child_status_change): Remove, folding its contents into ...
4080 (handle_child_signal): ... this signal handler. Now, this
4081 function is purely a handler for SIGCHLD, and is not called after
4082 a synchronous waitpid returns; the synchronous code is moved to
4083 wait_for_termination. There is no need to worry about reaping
4084 more than one child now.
4085 * sysdep.c (get_child_status, child_status_changed): New functions.
4086 (wait_for_termination): Now takes int * status and bool
4087 interruptible arguments, too. Do not record child status change;
4088 that's now the caller's responsibility. All callers changed.
4089 Reimplement in terms of get_child_status.
4090 (wait_for_termination_1, interruptible_wait_for_termination):
4091 Remove. All callers changed to use wait_for_termination.
4092 * syswait.h: Include <stdbool.h>, for bool.
4093 (record_child_status_change, interruptible_wait_for_termination):
4095 (record_deleted_pid, child_status_changed): New decls.
4096 (wait_for_termination): Adjust to API changes noted above.
4098 * bytecode.c, lisp.h (Qbytecode): Remove.
4099 No longer needed after 2012-11-20 interactive-p changes.
4101 2012-12-03 Eli Zaretskii <eliz@gnu.org>
4103 * xdisp.c (redisplay_window): If the cursor is visible, but inside
4104 the scroll margin, move point outside the margin. (Bug#13055)
4106 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
4108 * gtkutil.c (my_log_handler): New function.
4109 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
4111 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
4113 * lisp.h (modify_region): Rename to...
4114 (modify_region_1): ...new prototype.
4115 * textprop.c (modify_region): Now static. Adjust users.
4116 * insdel.c (modify_region): Rename to...
4117 (modify_region_1): ...new function to work with current buffer.
4118 Adjust comment and users. Use true and false for booleans.
4120 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
4122 * alloc.c (free_save_value): New function.
4123 (safe_alloca_unwind): Use it.
4124 * lisp.h (free_save_value): New prototype.
4125 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
4127 (save_excursion_restore): Adjust to match saved data structure.
4128 Use free_save_value to offload some work from GC. Drop obsolete
4131 2012-12-03 Chong Yidong <cyd@gnu.org>
4133 * fileio.c (Vauto_save_list_file_name): Doc fix.
4135 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
4137 * w32fns.c: Remove prototype of atof.

4140 (file_dialog_callback): Make it UINT_PTR.
4142 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
4145 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4146 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
4149 2012-12-03 Glenn Morris <rgm@gnu.org>
4151 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
4153 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
4155 Fix xpalloc confusion after memory is exhausted.
4156 * alloc.c (xpalloc): Comment fix.
4157 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
4158 and signals an error, do not clear charset_table_size, as
4159 charset_table is still valid.
4160 * doprnt.c (evxprintf): Clear *BUF after freeing it.
4162 Use execve to avoid need to munge environ (Bug#13054).
4163 * callproc.c (Fcall_process):
4164 * process.c (create_process):
4165 Don't save and restore environ; no longer needed.
4166 * callproc.c (child_setup):
4167 Use execve, not execvp, to preserve environ.
4169 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
4171 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).

4183 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
4185 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
4187 * xdisp.c (window_outdated): Remove eassert since it hits
4188 some suspicious corner cases (see Bug#13007 and Bug#13012).
4189 (mode_line_update_needed): New function.
4190 (redisplay_internal, redisplay_window): Use it.
4191 (ensure_selected_frame): New function.
4192 (redisplay_internal, unwind_redisplay): Use it.
4193 (redisplay_internal): Move comment about buffer_shared...
4194 (buffer_shared_and_changed): ...near to its real use.
4196 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
4198 * callproc.c (Fcall_process): Don't misreport vfork failure.
4200 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
4202 * callproc.c (Fcall_process): Fix vfork portability problems.
4203 Do not assume that fd[0], count, filefd, and save_environ survive
4204 vfork. Fix bug whereby wrong errno value could be reported for
4205 pipe failure. Some minor cleanups, too, as follows. Move buf and
4206 bufsize to the context where they're needed. Change new_argv to
4207 be of type char **, as this is more convenient and avoids casts.
4208 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
4209 Now local constants, not macros.
4211 2012-11-18 Kenichi Handa <handa@gnu.org>
4213 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
4214 for the variable "f".
4216 2012-11-13 Kenichi Handa <handa@gnu.org>
4218 * font.c (font_unparse_xlfd): Exclude special characters from the
4219 generating XLFD name.
4221 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
4223 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
4224 * dired.c (stat_uname, stat_gname):
4225 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
4227 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

4231 * fileio.c (Fcopy_file): Assume EISDIR is defined.
4232 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
4233 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
4234 * lread.c (readbyte_from_file): Assume EINTR is defined.
4235 * process.c (wait_reading_process_output, send_process) [subprocesses]:
4236 Assume EIO and EAGAIN are defined.
4237 * unexcoff.c (write_segment): Assume EFAULT is defined.
4239 2012-11-27 Eli Zaretskii <eliz@gnu.org>
4241 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
4244 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
4245 highlighting on the frame was cleared. Prevents assertion
4246 violations when repeatedly clicking on the "Top" link of the
4247 "bread-crumbs" in Info buffers.
4249 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
4251 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
4253 2012-11-24 Ken Brown <kbrown@cornell.edu>
4255 * keyboard.c (HAVE_MOUSE):
4256 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
4257 were always defined.
4259 2012-11-24 Eli Zaretskii <eliz@gnu.org>
4261 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
4262 between bpos_covered and bpos_max. This fixes cursor display when
4263 several display strings follow each other.
4265 * .gdbinit (pgx): If the glyph's object is a string, display the
4266 pointer to string data, rather than the value of the string object
4267 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
4269 * indent.c (Fvertical_motion): If the starting position is covered
4270 by a display string, return to one position before that, to avoid
4271 overshooting it inside move_it_to. (Bug#12930)
4273 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
4275 * frame.h (struct frame): Remove display_preempted member
4276 since all users are dead long ago.
4277 * nsterm.h (struct x_output): Use the only dummy member.
4278 * w32menu.c (pending_menu_activation): Remove since not
4280 (set_frame_menubar): Adjust user.
4281 * w32term.h (struct x_output): Drop outdated #if 0 code.
4282 (struct w32_output): Use bitfields for explicit_parent,
4283 asked_for_visible and menubar_active members.
4284 Drop unused pending_menu_activation member.
4285 * xterm.h (struct x_output): Drop outdated #if 0 code.
4286 Use bitfields for explicit_parent, asked_for_visible,
4287 has_been_visible and net_wm_state_hidden_seen members.
4289 2012-11-23 Eli Zaretskii <eliz@gnu.org>
4291 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
4292 of a literal "/". (Bug#12955)
4293 (gl-stamp): Invoke fc.exe directly, not through cmd.
4295 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
4297 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
4298 * dired.c: Assume HAVE_DIRENT_H.
4299 (NAMLEN): Remove, replacing with ...
4300 (dirent_namelen): New function. All uses changed. Use the GNU macro
4301 _D_EXACT_NAMELEN if available, as it's faster than strlen.
4302 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
4303 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
4304 * makefile.w32-in (DIR_H): Remove. All uses replaced with
4306 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
4307 * ndir.h: Rename to ../nt/inc/dirent.h.
4308 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
4309 Do not include <dirent.h>; no longer needed.
4310 * w32.c: Include <dirent.h> rather than "ndir.h".
4312 2012-11-23 Chong Yidong <cyd@gnu.org>
4314 * xftfont.c (xftfont_open): Remove duplicate assignment.
4316 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4318 * alloc.c (Fgarbage_collect): Unblock input after clearing
4319 gc_in_progress to avoid note_mouse_highlight glitch with GC.
4320 * frame.h (FRAME_MOUSE_UPDATE): New macro.
4321 * msdos.c (IT_frame_up_to_date): Use it here...
4322 * w32term.c (w32_frame_up_to_date): ...here...
4323 * xterm.c (XTframe_up_to_date): ...and here...
4324 * nsterm.m (ns_frame_up_to_date): ...but not here.
4325 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
4327 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
4328 Do not check whether GC is in progress.
4330 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4332 * xdisp.c (window_buffer_changed): New function.
4333 (update_menu_bar, update_tool_bar): Use it to
4334 simplify large 'if' statements.
4335 (redisplay_internal): Generalize commonly used
4336 'tail' and 'frame' local variables.
4338 2012-11-22 Eli Zaretskii <eliz@gnu.org>
4340 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
4341 with Windows system header.
4343 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
4345 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
4346 * alloc.c: Assume unistd.h exists.
4347 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
4348 * sysdep.c (get_current_dir_name): Assume getcwd exists.
4349 (getwd) [USG]: Remove; no longer needed.
4350 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
4351 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
4352 * w32.h (getcwd): Remove decl.
4354 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
4356 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
4357 Make it set selected_window as well.
4358 (update_tool_bar): Use it.
4360 2012-11-21 Ken Brown <kbrown@cornell.edu>
4362 * emacs.c (main): Set the G_SLICE environment variable for all
4363 Cygwin builds, not just GTK builds. See
4364 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
4366 2012-11-21 Eli Zaretskii <eliz@gnu.org>
4368 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4369 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
4370 Define for the MSVC compiler.
4372 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
4374 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
4375 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
4376 dostounix_filename. Prevents crashes down the road, because
4377 dostounix_filename assumes it gets a unibyte string.
4378 Reported by Michel de Ruiter <michel@sentient.nl>, see
4379 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
4381 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

4385 * lread.c (init_obarray): Set `function' fields to Qnil.
4386 * eval.c (Fcommandp): Ignore Qunbound.
4387 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
4388 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
4389 Test NILP rather than Qunbound.
4390 (Ffmakunbound): Set to Qnil.
4391 (Fsymbol_function): Never signal an error.
4392 (Finteractive_form): Ignore Qunbound.
4394 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
4396 * eval.c (interactive_p): Remove no-longer-used decl.
4398 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
4400 * xdisp.c (buffer_shared): Adjust comment.
4401 (buffer_shared_and_changed): New function.
4402 (prepare_menu_bars, redisplay_internal): Use it to
4403 decide whether all windows or frames should be updated.
4404 (window_outdated): New function.
4405 (text_outside_line_unchanged_p, redisplay_window): Use it.
4406 (redisplay_internal): Likewise. Fix indentation.
4408 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
4410 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
4411 (syms_of_eval): Remove corresponding defsubr.
4412 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
4414 2012-11-19 Daniel Colascione <dancol@dancol.org>
4416 * w32fns.c (Fx_file_dialog):
4417 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
4418 cygwin_convert_file_name*.
4420 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
4421 Rename cygwin_convert_path* to cygwin_convert_file_name*.
4423 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
4425 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
4427 2012-11-18 Eli Zaretskii <eliz@gnu.org>
4429 * w32select.c: Include w32common.h before w32term.h, so that
4430 windows.h gets included before w32term.h uses some of its
4431 features, see below.
4433 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
4435 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
4437 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
4439 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
4441 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
4442 (ns_select): Return at once if events are held (Bug#12834).
4444 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
4446 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
4447 Needed following 2012-10-20 change. (Bug#12902)
4449 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
4451 * w32proc.c (waitpid): Remove unused label get_result.
4453 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
4455 * makefile.w32-in (SYSWAIT_H): New macro.
4456 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
4457 ($(BLD)/sysdep.$(O)): Update dependencies.
4459 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4461 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
4462 * callproc.c (relocate_fd): Assume F_DUPFD.
4463 * emacs.c, term.c (O_RDWR): Remove.
4464 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
4465 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
4466 * nsterm.m: Assume <fcntl.h> exists.
4467 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
4468 (create_pty, Fmake_network_process, server_accept_connection)
4469 (wait_reading_process_output, init_process_emacs):
4471 (wait_reading_process_output): Put in a special case for WINDOWSNT
4472 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
4473 It's not clear this is needed, but it's a more-conservative change.
4474 (create_process): Assume FD_CLOEXEC.
4475 (create_process, create_pty): Assume O_NOCTTY.
4476 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
4477 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
4478 Omit if not DOS_NT, since F_GETFL is not defined there.
4479 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
4480 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
4482 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
4483 lack it, since gnulib guarantees this.
4484 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
4486 2012-11-17 Eli Zaretskii <eliz@gnu.org>
4488 * w32.c (faccessat): Pretend that directories have the execute bit
4489 set. Emacs expects that, e.g., in files.el:cd-absolute.
4491 * w32proc.c (create_child): Don't clip the PID of the child
4492 process to fit into an Emacs integer, as this is no longer a
4494 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
4495 reaping only the process specified by PID argument, if that is
4496 positive. Use PID instead of dead_child to know which process to
4497 reap. Wait for the child to die only if WNOHANG is not in
4499 (sys_select): Don't set dead_child.
4501 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
4502 as it is no longer needed.
4504 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
4506 (record_child_status_change): Remove the setting of
4507 record_at_most_one_child for the !WNOHANG case.
4509 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4511 Fix problems in ns port found by static checking.
4512 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
4513 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
4514 not to process group.
4515 (ns_select): Use emacs_write, not write, as that's more robust
4516 in the presence of signals.
4517 (fd_handler:): Check for read errors.
4519 2012-11-16 Glenn Morris <rgm@gnu.org>
4521 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
4523 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
4525 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
4527 2012-11-16 Eli Zaretskii <eliz@gnu.org>
4529 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
4530 use the same value of thread handle.
4531 (start_timer_thread): If the timer thread exited (due to error),
4532 clean up by closing the two handles it used. Duplicate the caller
4533 thread's handle here, so it gets duplicated only once, when
4534 launching the timer thread. Set priority of the timer thread, not
4536 (getitimer): Don't duplicate the caller thread's handle here.
4539 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
4541 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
4544 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
4546 Remove no-longer-used pty_max_bytes variable.
4547 * process.c (pty_max_bytes): Remove; unused.
4548 (send_process): Do not set it.
4550 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
4552 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
4553 Update dependencies.
4555 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
4557 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
4558 This follows up on the 2012-09-29 patch that removed indirection
4559 for the 'function' field. Reported by Sergey Vinokurov in
4560 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
4562 2012-11-14 Eli Zaretskii <eliz@gnu.org>
4564 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
4565 different name, as the MS runtime does not have such a function,
4566 and probably never will.) All callers changed. Ignore DIRFD
4567 value if PATH is an absolute file name, to match Posix spec
4568 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
4571 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
4573 * xdisp.c (echo_area_display, redisplay_internal):
4574 Omit redundant check whether frame_garbaged is set.
4576 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
4578 Use faccessat, not access, when checking file permissions (Bug#12632).
4579 This fixes a bug that has been present in Emacs since its creation.
4580 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
4581 which must set some sort of record. (Torek's bug report was against
4582 a predecessor of GNU Emacs, but GNU Emacs happened to have the
4583 same common flaw.) See Torek's Usenet posting
4584 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
4585 Posted: Fri Apr 8 14:18:56 1983.
4586 * Makefile.in (LIB_EACCESS): New macro.
4588 * callproc.c (init_callproc):
4589 * charset.c (init_charset):
4590 * fileio.c (check_existing, check_executable, check_writable)
4592 * lread.c (openp, load_path_check):
4593 * process.c (allocate_pty):
4595 Use effective UID when checking permissions, not real UID.
4596 * callproc.c (init_callproc):
4597 * charset.c (init_charset):
4598 * lread.c (load_path_check, init_lread):
4599 Test whether directories are accessible, not merely whether they exist.
4600 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
4601 * fileio.c (check_existing, check_executable, check_writable)
4603 Use symbolic names instead of integers for the flags, as they're
4605 (check_writable): New arg AMODE. All uses changed.
4606 Set errno on failure.
4607 (Ffile_readable_p): Use faccessat, not stat + open + close.
4608 (Ffile_writable_p): No need to call check_existing + check_writable.
4609 Just call check_writable and then look at errno. This saves a syscall.
4610 dir should never be nil; replace an unnecessary runtime check
4611 with an eassert. When checking the parent directory of a nonexistent
4612 file, check that the directory is searchable as well as writable, as
4613 we can't create files in unsearchable directories.
4614 (file_directory_p): New function, which uses 'stat' on most platforms
4615 but faccessat with D_OK (for efficiency) if WINDOWSNT.
4616 (Ffile_directory_p, Fset_file_times): Use it.
4617 (file_accessible_directory_p): New function, which uses a single
4618 syscall for efficiency.
4619 (Ffile_accessible_directory_p): Use it.
4620 * xrdb.c (file_p): Use file_directory_p.
4621 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
4622 * lread.c (openp): When opening a file, use fstat rather than
4623 stat, as that avoids a permissions race. When not opening a file,
4624 use file_directory_p rather than stat.
4625 (dir_warning): First arg is now a usage string, not a format.
4626 Use errno. All uses changed.
4627 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4628 that merely introduced a race.
4629 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4630 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4631 and similarly for the other O_* flags.
4632 * w32.c (sys_faccessat): Rename from sys_access and switch to
4633 faccessat's API. All uses changed.
4634 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4635 (magic_db): Rename from magic_file_p.
4636 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4637 char *, so that we don't have to test for file existence
4638 separately from opening the file for reading. This removes a race
4639 fixes a permission-checking problem, and simplifies the code.
4641 (file_p): Remove; no longer needed.
4643 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4645 Omit glyphs initialization at startup.

4657 frame's decode_mode_spec_buffer. This avoids crashes with very
4658 large values of FIELD_WIDTH argument to decode_mode_spec.
4661 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4663 Fix a race with verify-visited-file-modtime (Bug#12863).
4664 Since at least 1991 Emacs has ignored an mtime difference of no
4665 more than one second, but my guess is that this was to work around
4666 file system bugs that were fixed long ago. Since the race is
4667 causing problems now, let's remove that code.
4668 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4669 whose time stamp is off by no more than a second. Insist that the
4670 file time stamps match exactly.

4692 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4693 (x_window_to_menu_bar): Likewise.
4694 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4696 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4698 * data.c (Qdefalias_fset_function): Now static.
4700 Another tweak to vectorlike_header change.

4703 (next_in_free_list, set_next_in_free_list):
4704 New functions, which respect C's aliasing rules better.
4706 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4708 * window.c (list4i): Rename from 'quad'. All uses changed.
4709 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4711 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4713 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4714 warning about mixing declarations and code in ISO C90.
4716 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4718 * window.c (Fsplit_window_internal): Set combination limit of
4719 new parent window to t iff Vwindow_combination_limit is t;
4720 fixing a regression introduced with the change from 2012-09-22.
4721 (Fset_window_combination_limit): Fix doc-string.
4723 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4725 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4726 amount when the scroll margins are too large. When scrolling
4727 backwards in the buffer, give up if cannot reach point or the
4728 scroll margin within a reasonable number of screen lines.
4729 Fixes point position in window under scroll-up/down-aggressively when
4730 point is positioned many lines beyond the window top/bottom.
4733 * ralloc.c (relinquish): If real_morecore fails to return memory
4734 to the system, don't crash; instead, leave the last heap
4735 unchanged and return. (Bug#12774)

4760 (SCROLL_BAR_VEC_SIZE): Remove.
4761 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4763 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4765 Tweak last vectorlike_header change.
4766 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4767 vectorlike object on the free list. This is introduced to avoid
4768 some (but not all) pointer casting and aliasing problems, see
4769 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4770 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

4774 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4776 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4777 been removed, so remove them here also.

4781 * doc.c (Fdocumentation): Handle new property
4782 dynamic-docstring-function to replace the old ad-advice-info.
4784 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4786 * fns.c (Qeql, hashtest_eq): Now static.
4788 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>

4807 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4808 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4811 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4813 * image.c (xpm_make_color_table_h): Fix compiler error because
4814 make_hash_table changed.

4818 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4820 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4822 Use ad-hoc comparison function for the profiler's hash-tables.
4823 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4824 (make_log): Use them.
4825 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4826 call Fequal any more.

4836 (hash_lookup, hash_remove_from_table): Move assertion checking of
4837 hashfn result here. Check hash-equality before calling cmpfn.

4855 Shrink struct vectorlike_header to the only size field.
4856 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4858 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

4886 (allocate_buffer): Use BUFFER_PVEC_INIT.
4887 (live_vector_p): Adjust to match large vector.
4888 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4889 * buffer.h (struct buffer): Add next member.

4900 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4902 * keyboard.c (event_to_kboard): Do not dereference
4903 frame_or_window field of SELECTION_REQUEST_EVENT
4904 and SELECTION_CLEAR_EVENT events (Bug#12814).
4905 * xterm.h (struct selection_input_event): Adjust comment.
4907 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4909 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4910 such as Scroll Lock, if the respective keys are treated as
4911 function keys, not as modifiers. This avoids destroying non-ASCII
4912 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4914 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4916 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4918 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4920 Restore some duplicate definitions (Bug#12814).
4921 This undoes part of the 2012-11-03 changes. Some people build
4922 with plain -g rather than with -g3, and they need the duplicate
4923 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4924 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4925 Define as macros, as well as as enums or as constants.
4927 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4929 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4930 to keypad keys (Bug#12816).
4932 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4934 Minor adjustments of recently-changed frame functions.
4935 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4936 known to be a frame (we're in the FRAMEP branch).
4937 * lisp.h (Qframep): Remove decl. frame.h declares this.
4938 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4939 since they're meant for Lisp fixnum values.
4941 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4943 * window.c (Fwindow_combination_limit): Revert to the only
4944 required argument and adjust docstring as suggested in
4945 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4946 by Martin Rudalics <rudalics@gmx.at>.
4948 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>

4988 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4989 (Fwindow_line_height): Use it.
4990 (Fwindow_fringes): Use list3.
4991 (Fwindow_scroll_bars): Use list4.
4992 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4993 (Fwindow_combination_limit): Allow zero number of arguments.
4995 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4997 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4999 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
5000 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
5001 file descriptor 2 for standard error. (Bug#12805)
5003 2012-11-05 Chong Yidong <cyd@gnu.org>
5005 * process.c (wait_reading_process_output): Revert previous change.
5007 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
5009 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
5010 This removes code that has been obsolete since around 1990.
5011 * callproc.c (Fcall_process):
5013 * process.c (create_process):
5014 * term.c (dissociate_if_controlling_tty):
5015 Assume setsid exists.
5016 * callproc.c (child_setup): Assume setpgid exists and behaves as
5017 per POSIX.1-1988 or later.
5018 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
5019 * emacs.c (shut_down_emacs):
5020 * sysdep.c (sys_suspend, init_foreground_group):
5021 Assume getpgrp behaves as per POSIX.1-1998 or later.
5022 * msdos.c (setpgrp): Remove.
5023 (tcgetpgrp, setpgid, setsid): New functions.
5024 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.

5026 * w32proc.c (setpgrp): Remove.
5027 (setsid, tcgetpgrp): New functions.

5030 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
5031 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
5032 Do not assume that __fpending's result fits in int.
5034 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
5036 Remove EMACS_OUTQSIZE+sleep hack.
5037 * dispnew.c (update_frame_1): Remove hack for terminals slower
5038 than 2400 bps, which throttled Emacs by having it sleep.
5039 This code hasn't worked since at least 2007, when the multi-tty stuff
5040 was added, and anyway those old terminals are long dead.
5041 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
5042 without the dispnew.c change, as dispnew.c doesn't include systty.h.
5044 Fix data-loss with --version (Bug#9574).
5045 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
5046 as we can't assume that emacs_strerror is initialized, and strerror
5047 is good enough here.
5048 (main): Invoke atexit earlier, to catch earlier instances of
5049 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
5051 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
5053 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).

5056 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
5058 Fix data-loss with --batch (Bug#9574).
5059 * emacs.c: Include <close-stream.h>.
5060 (close_output_streams): New function.
5061 (main): Pass it to atexit, so that Emacs closes stdout and stderr
5062 and handles errors appropriately.
5063 (Fkill_emacs): Don't worry about flushing, as close_output_stream
5066 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
5067 The symptom is a diagnostic "GLib-WARNING **: In call to
5068 g_spawn_sync(), exit status of a child process was requested but
5069 SIGCHLD action was set to SIG_IGN and ECHILD was received by
5070 waitpid(), so exit status can't be returned." The diagnostic
5071 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
5072 The real bug is a race condition between Emacs and glib: Emacs
5073 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
5074 so that glib can't find it. Work around the bug by invoking
5075 waitpid only on subprocesses that Emacs itself creates.
5076 * process.c (create_process, record_child_status_change):
5077 Don't use special value -1 in pid field, as the caller now must
5078 know the pid rather than having the callee infer it.
5079 The inference was sometimes incorrect anyway, due to another race.
5080 (create_process): Set new 'alive' member if child is created.
5081 (process_status_retrieved): New function.
5082 (record_child_status_change): Use it.
5083 Accept negative 1st argument, which means to wait for the
5084 processes that Emacs already knows about. Move special-case code
5085 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
5086 processes that have already been waited for, by testing and
5087 clearing new 'alive' member.
5088 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
5089 now does this internally.
5090 (handle_child_signal): Let record_child_status_change do all
5091 the work, since we do not want to reap all exited child processes,
5092 only the child processes that Emacs itself created.
5093 * process.h (Lisp_Process): New boolean member 'alive'.
5095 Omit duplicate definitions no longer needed with gcc -g3.
5096 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
5097 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
5098 Define only as macros. There's no longer any need to also define
5099 these symbols as enums or as constants, since we now assume
5100 gcc -g3 when debugging.
5102 2012-11-03 Eli Zaretskii <eliz@gnu.org>
5104 * lisp.mk: Adjust comments to the fact that term/internal is now
5105 loaded from loadup.el.
5107 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
5108 (msdos_fatal_signal): New function.
5109 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
5112 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
5113 for GCC versions before 4.
5114 (emacs_raise): Define to call msdos_fatal_signal.
5116 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
5117 iterator when starting in the middle of a display or overlay
5120 2012-11-03 Chong Yidong <cyd@gnu.org>
5122 * process.c (wait_reading_process_output): Clean up the last
5125 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
5127 * process.c (wait_reading_process_output): Avoid a race condition
5128 with SIGIO delivery (Bug#11536).
5130 2012-11-03 Chong Yidong <cyd@gnu.org>
5132 * buffer.c (cursor_type): Untabify docstring.
5134 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5136 * frame.h (struct frame): Drop can_have_scroll_bars member
5137 which is meaningless for a long time. Adjust comments.
5138 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
5139 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
5141 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5143 * window.c (decode_next_window_args): Update window arg after
5144 calling decode_live_window and so fix crash reported at
5145 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
5146 by Juanma Barranquero <lekktu@gmail.com>.
5147 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
5148 * font.c (Ffont_at): Likewise.
5150 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
5152 * widget.c (resize_cb): New function.
5153 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
5154 (EmacsFrameResize): Check if all is up to date before changing frame
5157 2012-11-02 Eli Zaretskii <eliz@gnu.org>
5159 Implement backtrace output for fatal errors on MS-Windows.

5161 (BACKTRACE_LIMIT_MAX): New macro.
5162 (w32_backtrace): New function.
5163 (emacs_abort): Use w32_backtrace when the user chooses not to
5164 attach a debugger. Update the text of the abort dialog.
5166 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5168 Window-related stuff cleanup here and there.
5169 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
5170 Use decode_any_window.
5171 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
5172 * xdisp.c (Fformat_mode_line): Likewise.
5173 * font.c (Ffont_at): Use decode_live_window.
5174 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
5175 * window.c (decode_next_window_args): Likewise.
5176 (decode_any_window): Remove static.
5177 * window.h (decode_any_window): Add prototype.
5178 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
5179 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
5182 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5184 Remove pad from struct input_event.
5185 * termhooks.h (struct input_event): Remove padding field.
5187 * keyboard.c (event_to_kboard): Simplify because frame_or_window
5188 member is never cons for a long time. Adjust comment.
5189 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
5190 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
5191 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
5192 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
5194 2012-11-01 Eli Zaretskii <eliz@gnu.org>
5196 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
5198 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
5200 Fix crash when using Emacs as commit editor for git (Bug#12697).
5201 * callproc.c (setpgrp): Remove macro, as we now use setpgid
5202 and it is configured in conf_post.h.
5203 (Fcall_process): Don't invoke both setsid and setpgid; the former
5204 is enough, if it exists.
5205 * callproc.c (Fcall_process, child_setup):
5206 * process.c (create_process): Use setpgid.
5207 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
5209 * dispnew.c (init_display): Initialize the foreground group
5210 if we are running a tty display.
5211 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
5212 * lisp.h (init_foreground_group): New decl.
5213 * sysdep.c (inherited_pgroup): New static var.
5214 (init_foreground_group, tcsetpgrp_without_stopping)
5215 (narrow_foreground_group, widen_foreground_group): New functions.
5216 (init_sys_modes): Narrow foreground group.
5217 (reset_sys_modes): Widen foreground group.
5219 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
5221 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
5223 2012-10-31 Martin Rudalics <rudalics@gmx.at>
5225 * minibuf.c (read_minibuf): Restore current buffer since
5226 choose_minibuf_frame calling Fset_frame_selected_window may
5227 change it (Bug#12766).
5229 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
5231 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
5233 2012-10-30 Kenichi Handa <handa@gnu.org>
5235 * font.c (Ffont_at): If WINDOW is specified and it is not
5236 displaying the current buffer, signal an error.
5238 2012-10-29 Daniel Colascione <dancol@dancol.org>
5240 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
5241 In preparation for fixing bug#12739, move these functions from
5244 * coding.h, coding.c: ... to here, and compile them only when
5245 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
5246 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
5248 2012-10-28 Eli Zaretskii <eliz@gnu.org>
5250 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
5251 (timer_loop, getitimer, setitimer): Use it instead of
5252 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
5254 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
5257 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
5259 * nsterm.m (NO_APPDEFINED_DATA): New define.
5260 (last_appdefined_event_data): New variable
5261 (last_appdefined_event): Remove.
5262 (ns_select): Initialize t from last_appdefined_event_data instead
5263 of [last_appdefined_event data1].
5264 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
5265 remove last_appdefined_event (Bug#12698).
5267 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
5269 * frame.c (x_set_font): Catch internal error.
5271 2012-10-27 Eli Zaretskii <eliz@gnu.org>
5273 Avoid overflow in w32 implementation of interval timers.
5274 When possible, for ITIMER_PROF count only times the main thread
5276 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
5277 'volatile ULONGLONG' types. All the other data which was
5278 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
5279 (GetThreadTimes_Proc): New typedef.
5280 (w32_get_timer_time): New function, returns a suitable time value
5282 (timer_loop): Enter critical section when accessing ULONGLONG
5283 values of the itimer_data struct, as these accesses are no longer
5284 atomic. Call 'w32_get_timer_time' instead of 'clock'.
5285 Remove unused variable.
5286 (init_timers): Initialize s_pfn_Get_Thread_Times.
5287 (start_timer_thread): Don't assign itimer->caller_thread here.
5288 (getitimer): Assign itimer->caller_thread here.
5289 (setitimer): Always call getitimer to get the value of ticks_now.
5290 (sys_spawnve): Avoid compiler warning about format mismatch.
5292 2012-10-26 Eli Zaretskii <eliz@gnu.org>
5294 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
5295 mouse movement events if the menu bar is active. This avoids
5296 producing a busy "hour-glass" cursor by Windows if the mouse
5297 pointer is positioned over a tooltip shown for some menu item.
5299 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
5301 Don't assume process IDs fit in int.
5302 * emacs.c (shut_down_emacs) [!DOS_NT]:
5303 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
5304 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
5305 Use pid_t, not int, to store process IDs, as 'int'
5306 is not wide enough on a few platforms (e.g., AIX and IRIX).
5308 2012-10-23 Kenichi Handa <handa@gnu.org>
5310 The following change is to make face-font-rescale-alist work
5311 correctly for non-ASCII fonts.
5313 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
5314 (font_open_for_lface): Handle Vface_font_rescale_alist.
5316 2012-10-23 Chong Yidong <cyd@gnu.org>
5318 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
5320 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

5329 2012-10-21 Glenn Morris <rgm@gnu.org>
5331 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
5333 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
5335 Port to OpenBSD 5.1.
5336 * frame.c (Fmouse_position, Fmouse_pixel_position):
5337 * xdisp.c (produce_stretch_glyph):
5338 Declare local vars only when they're needed.
5339 This is clearer and avoids a warning on OpenBSD about unused vars.
5340 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
5341 This is safer, and avoids OpenBSD warnings about unused vars.
5342 * keyboard.c (record_menu_key): Remove unnecessary decl.
5343 (poll_timer): Define only if POLL_FOR_INPUT is defined.
5344 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
5345 as our definition clashes with OpenBSD's.
5346 * xfaces.c (load_face_colors, check_lface_attrs)
5347 (get_lface_attributes_no_remap, get_lface_attributes)
5348 (lface_fully_specified_p, x_supports_face_attributes_p)
5349 (tty_supports_face_attributes_p, face_fontset, realize_face)
5350 (realize_x_face, realize_tty_face):
5351 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
5352 merely Lisp_Object *. This is more informative and avoids
5353 a warning on OpenBSD about accessing beyond an object's size.
5355 2012-10-20 Chong Yidong <cyd@gnu.org>
5357 * lread.c (Fload): Doc fix (Bug#12592).
5359 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
5361 * font.c (Ffont_at): Fix previous change.
5363 2012-10-19 Eli Zaretskii <eliz@gnu.org>
5365 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
5366 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
5369 * alloc.c (NSTATICS): Decrease to 0x800.
5371 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

5376 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
5378 * nsterm.m (ns_select): Check writefds before call to
5379 FD_ISSET (Bug#12668).
5381 2012-10-18 Daniel Colascione <dancol@dancol.org>
5383 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
5384 (staticpro): If we run out of staticpro slots, die with an
5385 informative error instead of just calling emacs_abort.
5387 2012-10-18 Martin Rudalics <rudalics@gmx.at>
5389 Fix two flaws reported by Dmitry Antipov.
5390 * window.c (Ftemp_output_buffer_show): Remove.

5411 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
5412 (sys_link): Add prototypes.
5414 * w32.c: Include w32select.h.
5415 (sys_access, e_malloc, sys_select): Add prototypes.

5430 * cygw32.c (Fcygwin_convert_path_to_windows)
5431 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
5432 Lisp_Object values. (Bug#12661)
5434 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
5435 to Lisp_Object. (Bug#12661)

5480 * dbusbind.c: Fix cygw32 build break when compiling with dbus
5481 enabled by undefining the symbol "interface", which the platform
5482 headers define to something incompatible.
5484 2012-10-14 Daniel Colascione <dancol@dancol.org>
5486 * image.c (init_tiff_functions, init_imagemagick_functions)
5487 (init_svg_functions): Fix cygw32 build break by using these
5488 functions only when WINDOWSNT _and_ HAVE_NTGUI.

5507 2012-10-13 Paul Eggert <eggert@cs.ucla.edu>
5509 Fix some stat-related races.
5510 * fileio.c (Fwrite_region): Avoid race condition if a file is
5511 removed or renamed by some other process immediately after Emacs
5512 writes it but before Emacs stats it. Do not assume that stat (or
5514 * image.c (slurp_file): Resolve the file name with fopen + fstat
5515 rather than stat + fopen.

5543 * fileio.c (check_existing): New function.
5544 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
5545 instead of calling 'stat', when what's needed is to check whether
5546 a file exists. This avoids expensive system calls on MS-Windows.
5549 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
5551 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
5552 determine whether a file exists and is not a directory.
5554 * lisp.h (check_existing): Add prototype.
5556 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
5558 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

5588 Use bool for booleans.
5589 * lread.c (safe_to_load_version): Rename from safe_to_load_p,
5590 as it's not a predicate. All uses changed. Omit unnecessary

5643 Use unsigned for counter where wraparound-on-overflow is desired,
5644 since unsigned is guaranteed to have that behavior and signed is not.
5645 (read_char): Use ptrdiff_t for string length.
5646 (get_input_pending): Remove first argument, since it was always
5647 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5648 and behave as if it had that value. Return new value of
5649 input_pending. All callers changed.
5650 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5651 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
5653 * keymap.c (push_key_description): Omit last arg, which was always 1.
5654 All callers changed.
5656 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
5658 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

5674 Don't include termopts.h.
5676 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
5678 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
5680 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5682 * commands.h (immediate_quit): Remove duplicate decl.
5684 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
5686 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
5688 (nsfont_open): Remove setting of Vfonts_in_cache.
5689 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
5691 2012-10-09 Eli Zaretskii <eliz@gnu.org>
5693 * w32fns.c (w32_last_error): Change the return value to DWORD, to
5694 match what GetLastError returns. Explain why the function is
5697 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5698 'is_tooltip_frame', to avoid confusion with its global namesake.
5700 2012-10-08 Daniel Colascione <dancol@dancol.org>
5702 * xdisp.c (start_hourglass): Call w32_note_current_window when
5703 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5704 build that caused Emacs to display the hourglass cursor forever.
5706 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5707 which is broken under remote desktop, calculate the number of
5708 colors available for a display based on the display's number of
5709 planes and number of bits per pixel per plane. (bug#10397).
5711 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5713 * nsfont.m (Vfonts_in_cache): New variable.
5714 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5715 are used. Add cached fonts to Vfonts_in_cache.
5716 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5718 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5720 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5722 (FONT_H): Define after FRAME_H.
5723 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5724 Update dependencies.
5726 * w32term.c: Remove leftover declaration of keyboard_codepage.
5728 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5730 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5731 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5732 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5733 (GLOBAL_SOURCES): Add cygw32.c.

5736 ($(BLD)/w32console.$(O)):
5737 ($(BLD)/w32fns.$(O)):
5738 ($(BLD)/w32heap.$(O)):
5739 ($(BLD)/w32menu.$(O)):
5740 ($(BLD)/w32proc.$(O)): Add w32common.h.
5742 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5744 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5746 2012-10-08 Daniel Colascione <dancol@dancol.org>
5748 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5749 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5750 accidental message numbering hole. Change other messages to
5753 * w32select.h (HAVE_W32SELECT): Remove.
5755 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5756 w32common.h instead of w32heap.h.
5758 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
5759 (get_allocation_unit, get_processor_type, get_w32_major_version)
5760 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5761 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5762 (OS_NT, os_subtype, cache_system_info): Move declarations to
5765 * w32heap.c: Include w32common.h.
5766 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5767 (w32_minor_version, w32_build_number, w32_subtype):
5768 Remove duplicate definitions.
5770 * w32fns.c: Include w32common.h; include w32heap.h only in
5773 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5774 Use `report_file_error' instead of `error' in order to better
5775 inform users of what went wrong. Increase NTGUI_UNICODE file
5776 dialog box file name length to 32k, the maximum allowed by the NT
5779 * w32common.h: New file.
5780 (ROUND_UP, ROUND_DOWN, get_page_size)
5781 (get_allocation_unit, get_processor_type, get_w32_major_version)
5782 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5783 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5784 (OS_NT, os_subtype, cache_system_info): Move here.
5786 * unexw32.c, unexcw.c: Include w32common.h.
5788 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5789 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5790 to call syms_of_w32select.
5792 * cygw32.h: Remove obsolete EXFUN declarations.
5794 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5796 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5797 of w32inevt.o from SOME_MACHINE_OBJECTS.
5799 2012-10-08 Daniel Colascione <dancol@dancol.org>
5801 * image.c: Permanent fix for JPEG compilation issue --- limit
5802 jpeglib `boolean' redefinition to Cygwin builds.
5804 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5806 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5808 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5811 2012-10-08 Daniel Colascione <dancol@dancol.org>
5813 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5814 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5815 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5816 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5817 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5818 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5819 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5820 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5821 now a supported configuration.
5823 * Makefile.in: consolidate image variables into LIBIMAGE; add
5824 W32_OBJ and W32_LIBS. Compile new files.
5827 (_DebPrint) declare tracing facility for W32 debugging. We need
5828 to unify tracing later.
5830 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5831 unconditional use of W32 Unicode functions. Cygwin runs only on
5832 100% Unicode operating systems.
5834 * cygw32.c: New file. Define Cygwin-specific facilities.
5835 (Fcygwin_convert_path_to_windows)
5836 (Fcygwin_convert_path_from_windows): New user functions for
5837 accessing Cygwin path-munging routines.
5839 * cygw32.h: New file.
5840 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5841 UTF-16LE strings temporarily inside non-Lisp-visible string
5844 (w32_strerror): Just what it says on the tin.
5846 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5847 also run for Cygwin; both systems have the same problem with using
5848 GUI facilities in a forked child. Also call syms_of_cygw32,
5849 syms_of_w32select in correct places.
5851 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5852 needs fork-then-exec for daemon launching.
5854 * font.h: Include frame.h.
5856 * image.c: Use the image library cache machinery only when we're
5857 compiling for native WINDOWSNT; Cygwin can use shared libraries
5858 like any other Unixlike system.
5860 * keyboard.c: Clarify a comment regarding the input loop.
5862 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5863 functions directly instead of trying to detect at runtime that our
5864 host operating system supports them. We make this change for two
5865 reasons: Cygwin lacks support for the multibyte character
5866 conversion functions used by the legacy menu code, and Cygwin
5867 never needs to rely on non-Unicode APIs.
5869 * unexw32.c (hinst): Declare extern.
5871 * w32.c: Change header order;
5872 (w32_strerror): Move to w32fns.c because we need it for
5873 non-WINDOWSNT builds.
5875 * w32.h: Add #error macro to make sure we don't include w32.h for
5876 Cygwin builds. Remove w32select declarations.
5878 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5879 w32fns.c. w32console.c is WINDOWSNT-only.
5881 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5882 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5884 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5885 (w32_major_version, w32_minor_version, w32_build_number)
5886 (os_subtype, sound_type): Define here
5887 (w32_defined_color): Make color parameter const for consistency
5888 with other _defined_color functions.
5889 (w32_createwindow): Unconditionally call w32_init_class instead of
5890 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5891 through the code is complex and unnecessary because class
5892 registration is practically free.
5893 (w32_name_of_message): New EMACSDEBUG-only function.
5894 (Fset_message_beep): Move here
5895 (Fx_open_connection): Require that the display name for Windows be
5896 "w32" for consistency, emacsclient disambiguation, and maybe, one
5897 day, multi-window-system support.
5898 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5899 Cygwin files for W32 GUI facilities, since these clearly don't
5900 expect Cygwin names.
5901 (_DebPrint): Define.
5902 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5903 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5904 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5905 (w32_last_error): Remove.
5907 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5909 * w32heap.c (syspage_mask): Declare here.
5910 (cache_system_info): Remove.
5912 * w32inevt.c (faked_key): Define globally, not statically.
5913 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5914 (w32_console_toggle_lock_key): Move to w32fns.c.
5916 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5918 * w32proc.c (_DebPrint): Move to w32fns.c.
5919 * w32select.c: Include string.h, stdio.h for Cygwin.
5920 * w32select.h: New File.
5922 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5924 (w32_message_fd): New variable. Under Cygwin, holds the file
5925 descriptor the system used to tell us about pending thread
5928 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5929 that prevented compilation under non-WINDOWSNT systems.
5931 (w32_initialize): Open /dev/windows and assign it to
5932 w32_message_fd. Provide w32 feature.
5934 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5935 (WM_EMACS_INPUT_READY): add.
5936 (prepend_msg, w32_message_fd): Declare globally.
5939 (keyboard_handle): Use only when WINDOWSNT.
5940 (notify_msg_ready): New function. Posts a message to the main
5941 thread's message queue under CYGWIN, which wakes up the main
5942 thread from select(2) by making the /dev/windows file descriptor
5943 ready. Under WINDOWSNT, it sets an event the same way the old
5946 (post, prepend_msg): Actually call notify_msg_ready instead of
5947 setting the input event directly.
5949 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5951 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5952 but it still has blocs in it, don't return it to the system,
5953 instead of aborting. (Bug#12402)
5955 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5957 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5959 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5960 MAC_OS_X_VERSION_10_6.
5961 (syms_of_nsterm): Remove comment about Panther and above for

5965 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5967 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5968 MAC_OS_X_VERSION_10_4.
5970 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5971 MAC_OS_X_VERSION_10_2.
5973 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5975 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5976 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5978 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5979 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5980 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5981 Remove ns_in_resize check.
5982 (ns_clear_frame_area): Remove resize handle code.
5984 * nsfns.m (ns_in_resize): Remove.
5985 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5986 Remove ns_in_resize check.
5988 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5990 Improve sys_siglist detection.
5991 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5992 defined as a macro, as is done in Solaris.
5993 (sys_siglist_entries): New macro.
5994 (save_strsignal): Use it.
5995 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5996 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5998 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
6000 * nsfns.m (Fx_create_frame): Call x_default_parameter with
6001 fullscreen/Fullscreen.
6003 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
6004 tobar_height is new.
6006 * nsterm.m (x_make_frame_visible): Check for fullscreen.
6007 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
6008 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
6009 (windowDidResize:): Check for correct window if old style fullscreen.
6010 Capitalize word in comment. Remove incorrect comment.
6011 (initFrameFromEmacs:): tbar_height renamed tibar_height.
6012 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
6013 error in drawing background.
6014 (toggleFullScreen:): Remove comment. Rearrange calls.
6015 Set toolbar values to zero, save old height in tobar_height.

6019 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
6021 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
6023 2012-10-05 Eli Zaretskii <eliz@gnu.org>
6025 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
6027 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
6028 that time stamps of directories could also be changed.
6029 Don't request the too broad GENERIC_WRITE, only the more restrictive
6030 FILE_WRITE_ATTRIBUTES access rights.
6032 * fileio.c (Fset_file_times): Special-case ignoring errors for
6033 directories only on MSDOS, not on MS-Windows.
6035 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
6037 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
6039 2012-10-04 Eli Zaretskii <eliz@gnu.org>
6041 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
6042 see whether CreateFile failed.
6044 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
6046 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
6047 to avoid similar races.
6048 * keyboard.c (pending_signals): Now bool, not int.
6050 Port timers to OpenBSD, plus check for timer failures.
6051 OpenBSD problem reported by Han Boetes.
6052 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
6054 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
6055 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
6056 like OpenBSD, which has timer_settime but does not declare it.
6057 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
6058 whether to use itimerspec-related primitives. All uses of
6059 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
6061 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
6063 * profiler.c (handle_profiler_signal): Fix a malloc race
6064 that caused Emacs to hang on Fedora 17 when profiling Lisp.
6066 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
6068 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
6070 2012-10-02 Eli Zaretskii <eliz@gnu.org>
6072 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
6073 consistent with the change in return value of 'safe_strsignal'.
6075 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
6077 Prefer plain 'static' to 'static inline' (Bug#12541).

6085 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6086 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
6087 Now 'static', not 'static inline'.
6089 Count overruns when profiling; change units to ns.
6090 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
6091 Give extra weight to samples after overruns, to attempt to count
6092 the time more accurately.
6093 (setup_cpu_timer): Change sampling interval units from ms to ns, since
6094 the underlying primitives nominally do ns.
6095 (Fprofiler_cpu_start): Document the change. Mention that
6096 the sampling intervals are only approximate.
6098 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6100 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
6102 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
6103 case for the special 0 coding-system.
6105 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
6106 (Fmake_overlay): Remove redundant tests.
6107 (fix_start_end_in_overlays): Remove redundant recentering.
6109 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
6111 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
6112 Update dependencies.
6114 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6116 Fix a malloc race condition involving strsignal.
6117 A signal can arrive in the middle of a malloc, and Emacs's signal
6118 handler can invoke strsignal, which can invoke malloc, which is
6119 not portable. This race condition bug makes Emacs hang on GNU/Linux.
6120 Fix it by altering the signal handler so that it does not invoke
6122 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
6123 * process.c (status_message): Use const pointer, in case strsignal
6124 is #defined to safe_strsignal.
6125 * sysdep.c (sys_siglist, init_signals): Always define and
6126 initialize a substitute sys_siglist if the system does not define
6127 one, even if HAVE_STRSIGNAL.
6128 (safe_strsignal): Rename from strsignal. Always define,
6129 using sys_siglist. Return a const pointer.
6130 * syssignal.h (safe_strsignal): New decl.
6131 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
6133 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6135 * w32proc.c (timer_loop): Fix code that waits for timer
6136 expiration, to avoid high CPU usage.
6138 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
6140 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
6141 (sweep_weak_table): Remove redundant prototypes.
6143 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
6145 * emacs.c: Move the inclusion of TERM_HEADER after including
6146 windows.h on WINDOWSNT. This avoids compilation problems with
6149 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6151 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
6152 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
6153 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
6154 as the previous version used 'void *'.
6156 * ralloc.c (ROUNDUP): Fix last change.
6157 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
6160 * w32proc.c <disable_itimers>: New static flag.
6161 (init_timers): Initialize it to zero, after creating the critical
6162 sections used by the timer threads.
6163 (term_timers): Set to 1 before deleting the critical sections.
6164 (getitimer, setitimer): If disable_itimers is non-zero, return an
6165 error indication without doing anything. Reported by Fabrice
6166 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
6167 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
6169 [!HAVE_SETITIMER]: Behave as the previous version that didn't
6172 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
6173 term_ntproc after all the other bookkeeping, to get timers working
6174 as long as possible.
6176 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6178 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
6179 Suggested by Juri Linkov in
6180 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
6182 Prefer plain 'static' to 'static inline' (Bug#12541).
6183 With static functions, modern compilers inline pretty well by
6184 themselves; advice from programmers often hurts as much as it helps.
6185 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
6186 this change shrinks the text size of the Emacs executable by 1.1%
6187 without affecting CPU significantly in my benchmark.
6188 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

6270 Revert the FOLLOW-SYMLINKS change for file-attributes.
6271 Doing it right would require several changes to Tramp, and there's
6272 not enough time to get that tested before the freeze today.
6273 * dired.c (directory_files_internal, Ffile_attributes):
6276 * frame.c (x_report_frame_params): Port better to wider ints.
6277 Do not assume that EMACS_UINT is the same width as uprintmax_t,
6278 or that pointers can be printed in 15 decimal digits.
6279 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

6403 2012-09-30 Kenichi Handa <handa@gnu.org>
6405 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
6406 to the buffer relocation which may be caused by ccl_driver.

6457 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
6459 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
6460 Suggested by Eli Zaretskii in
6461 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
6463 2012-09-30 Eli Zaretskii <eliz@gnu.org>
6465 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
6466 HAVE_TIMER_SETTIME is defined.
6468 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
6470 Profiler improvements: more-accurate timers, overflow checks.
6471 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
6472 signal.h, setjmp.h. Include systime.h instead.
6473 (saturated_add): New function.
6474 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
6475 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
6476 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
6478 (enum profiler_cpu_running): New enum.
6479 (profiler_cpu_running): Now of that enum type, not bool.
6480 All uses changed to store the new value.
6481 (handle_profiler_signal): Rename from sigprof_handler_1,
6482 for consistency with other handlers. Do not check whether
6483 cpu_log is a hash-table if garbage collecting, since it
6484 doesn't matter in that case.
6485 (deliver_profiler_signal): Rename from sigprof_handler,
6486 for consistency with other handlers.
6487 (setup_cpu_timer): New function, with much of what used to be in
6488 Fprofiler_cpu_start. Check for out-of-range argument.
6489 Prefer timer_settime if available, and prefer
6490 thread cputime clocks, then process cputime clocks, then
6491 monotonic clocks, to the old realtime clock. Use make_timeval
6492 to round more-correctly when falling back to setitimer.
6493 (Fprofiler_cpu_start): Use it.
6494 (Fprofiler_cpu_stop): Prefer timer_settime if available.
6495 Don't assume that passing NULL as the 2nd argument of setitimer
6496 is the same as passing a pointer to all-zero storage.
6497 Ignore SIGPROF afterwards.
6498 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
6499 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
6500 non-fatal signal handlers. Ignore SIGPROF on startup.
6501 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
6502 in profiler.c, since sysdep.c now uses it.
6504 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
6505 Suggested by Eli Zaretskii in
6506 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

6519 (Fbacktrace_frame): Adjust accordingly.
6521 2012-09-28 Glenn Morris <rgm@gnu.org>
6523 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
6524 (Frun_hook_with_args_until_failure): Doc fixes.

6528 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
6529 Qautomatic_redisplay and change the symbol name. All users changed.

6556 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
6558 * character.h (MAYBE_UNIFY_CHAR): Remove.
6559 * charset.c, charset.h (maybe_unify_char): Now static.
6560 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
6561 Since this stuff is now private to charset.c, there's no need for
6562 a public macro and no need to inline by hand.
6564 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
6565 Stefan Monnier <monnier@iro.umontreal.ca>
6566 Juanma Barranquero <lekktu@gmail.com>

6595 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
6597 Prefer POSIX timers if available.
6598 They avoid a race if the timer is too close to the current time.
6599 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
6600 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
6601 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
6603 2012-09-25 Eli Zaretskii <eliz@gnu.org>
6605 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
6606 CHAR_STRING_ADVANCE.
6607 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
6608 STRING_CHAR_ADVANCE.

6624 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
6626 * w32.h (Vlibrary_cache): Do not declare.
6628 2012-09-25 Eli Zaretskii <eliz@gnu.org>
6630 * w32proc.c (sys_signal): Handle all signals defined by the
6631 MS-Windows runtime, not just SIGCHLD. Actually install the signal
6632 handlers for signals supported by Windows. Don't override
6633 term_ntproc as the handler for SIGABRT.
6634 (sigaction): Rewrite to call sys_signal instead of duplicating its
6636 (sys_kill): Improve commentary.
6638 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6639 consistency with a signature of a signal handler. All callers
6641 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6642 install term_ntproc as a signal handler for SIGABRT, as that
6643 should be done by the dumped Emacs.
6645 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6647 * w32select.c (term_w32select): Protect against repeated
6648 invocation by setting clipboard_owner to NULL after calling
6651 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
6652 and term_ntproc to their modified signatures.
6654 * character.c (char_string, string_char): Remove calls to
6655 MAYBE_UNIFY_CHAR. See the discussion starting at
6656 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
6659 2012-09-25 Chong Yidong <cyd@gnu.org>
6661 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
6663 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
6665 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
6666 when encountering an unknown bytecode.
6668 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
6670 image.c, indent.c: Use bool for booleans.
6671 * dispextern.h (struct image_type): Members valid_p, load, init
6672 now return bool, not int. All uses changed.
6673 * image.c: Omit unnecessary static decls.
6674 (x_create_bitmap_mask, x_build_heuristic_mask):

6710 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6712 Move pid_t related decls out of lisp.h.
6713 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6714 (interruptible_wait_for_termination):
6715 Move these decls from lisp.h to syswait.h, since they use pid_t.
6716 Needed on FreeBSD; see Herbert J. Skuhra in
6717 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6718 * callproc.c: Include syswait.h.

6764 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6766 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6767 fatal_error_backtrace.
6769 * w32proc.c (sys_kill): Undo last change: don't do anything when
6770 invoked to deliver SIGABRT to our own process. This is now
6771 handled by emacs_raise.
6773 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6775 * w32term.c (w32_read_socket): Remove leftover reference to
6776 interrupt_input_pending.
6778 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6780 Do not use SA_NODEFER.
6781 Problem reported by Dani Moncayo in
6782 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6784 * sysdep.c (emacs_abort): Do not reset signal handler.
6785 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6786 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6787 wanted even on POSIXish hosts, and it doesn't work on Windows.
6789 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6791 * xterm.c (x_term_init): Call fixup_locale before and after calling
6792 gtk_init (Bug#12392).
6794 2012-09-23 Chong Yidong <cyd@gnu.org>
6796 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6797 Vdynamic_library_alist.
6799 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6800 (Fgnutls_available_p): Caller changed.
6802 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6803 (Flibxml_parse_xml_region): Likewise.
6805 * dispextern.h (struct image_type): Remove arg from init function.
6807 * image.c (Finit_image_library, lookup_image_type)
6808 (define_image_type): Remove now-unneeded second arg.
6809 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6810 (init_tiff_functions, init_gif_functions, init_svg_functions):
6811 Arglist and w32_delayed_load calling convention changed.
6812 (gs_type): Remove init_gs_functions; there is no such function.
6813 (valid_image_p, make_image): Fix caller to lookup_image_type.
6815 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6817 Simplify and avoid signal-handling races (Bug#12471).
6819 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6820 Avoid recursive loop if there's a fatal error in the function itself.
6821 * atimer.c (pending_atimers):
6822 * blockinput.h: Don't include "atimer.h"; no longer needed.
6823 (interrupt_input_pending): Remove. All uses removed.
6824 pending_signals now counts both atimers and ordinary interrupts.
6825 This is less racy than having three separate pending-signal flags.
6826 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6828 Rename from their upper-case counterparts BLOCK_INPUT,
6829 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6830 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6831 This makes it easier to access volatile variables more accurately.
6832 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6833 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6834 that's more reliable if the code is buggy and sets
6835 interrupt_input_blocked to a negative value. All uses changed.
6836 * atimer.c (deliver_alarm_signal):
6837 Remove. No need to deliver this to the parent; any thread can
6838 handle this signal now. All uses replaced by underlying handler.
6839 * atimer.c (turn_on_atimers):
6840 * dispnew.c (handle_window_change_signal):
6841 * emacs.c (handle_danger_signal):
6842 * keyboard.c (kbd_buffer_get_event):
6843 Don't reestablish signal handler; not needed with sigaction.
6844 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6846 Rework to avoid unnecessary accesses to volatile variables.
6847 (UNBLOCK_INPUT_TO): Now a function.
6848 (totally_unblock_input, unblock_input): New decls.
6849 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6850 (init_data): Remove. Necessary stuff now done in init_signal.
6851 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6852 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6853 (fatal_error_code): Remove; no longer needed.
6854 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6855 it doesn't always backtrace. All uses changed. No need to reset
6856 signal to default, since sigaction and/or die does that for us now.
6857 Use emacs_raise (FOO), not kill (getpid (), FOO).
6858 (main): Check more-accurately whether we're dumping.
6859 Move fatal-error setup to sysdep.c
6860 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6861 * gtkutil.c (xg_get_file_name, xg_get_font):
6862 Remove no-longer-needed signal-mask manipulation.
6863 * keyboard.c, process.c (POLL_FOR_INPUT):
6864 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6865 * keyboard.c (read_avail_input): Remove.
6866 All uses replaced by gobble_input.
6867 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6868 (kbd_buffer_store_event_hold, gobble_input):
6869 (record_asynch_buffer_change) [USABLE_SIGIO]:
6870 (store_user_signal_events):
6871 No need to mess with signal mask.
6872 (gobble_input): If blocking input and there are terminals, simply
6873 set pending_signals to 1 and return. All hooks changed to not
6874 worry about whether input is blocked.
6875 (process_pending_signals): Clear pending_signals before processing
6876 them, in case a signal comes in while we're processing.
6877 By convention callers now test pending_signals before calling us.
6878 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6879 New functions, to support changes to blockinput.h.
6880 (handle_input_available_signal): Now extern.
6881 (reinvoke_input_signal): Remove. All uses replaced by
6883 (quit_count): Now volatile, since a signal handler uses it.
6884 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6885 All callers changed. Block SIGINT only if not already blocked.
6886 Clear sigmask reliably, even if Fsignal returns, which it can.
6887 Omit unnecessary accesses to volatile var.
6888 (quit_throw_to_read_char): No need to restore sigmask.
6889 * keyboard.c (gobble_input, handle_user_signal):
6890 * process.c (wait_reading_process_output):
6891 Call signal-handling code rather than killing ourselves.
6892 * lisp.h: Include <float.h>, for...
6893 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6894 (pending_signals): Now volatile.
6895 (syms_of_data): Now const if IEEE floating point.
6896 (handle_input_available_signal) [USABLE_SIGIO]:
6897 (terminate_due_to_signal, record_child_status_change): New decls.
6898 * process.c (create_process): Avoid disaster if memory is exhausted
6899 while we're processing a vfork, by tightening the critical section
6901 (send_process_frame, process_sent_to, handle_pipe_signal)
6902 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6904 (send_process): No need for setjmp/longjmp any more, since the
6905 SIGPIPE stuff is now gone. Instead, report an error if errno
6907 (record_child_status_change): Now extern. PID and W are now args.
6908 Return void, not bool. All callers changed.
6909 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6910 Remove. All uses removed. This bug should be fixed now in a
6912 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6913 and record the child status change directly. This avoids the
6914 need to futz with the signal mask.
6915 (process_fatal_action): Move here from emacs.c.
6916 (emacs_sigaction_flags): New function, containing
6917 much of what used to be in emacs_sigaction_init.
6918 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6919 caught by emacs, to make races less likely.
6920 (deliver_process_signal): Rename from handle_on_main_thread.
6922 (BACKTRACE_LIMIT_MAX): Now at top level.
6923 (thread_backtrace_buffer, threadback_backtrace_pointers):
6925 (deliver_thread_signal, deliver_fatal_thread_signal):
6926 New functions, for more-accurate delivery of thread-specific signals.
6927 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6928 (deliver_arith_signal): Handle in this thread, not
6929 in the main thread, since it's triggered by this thread.
6930 (maybe_fatal_sig): New function.
6931 (init_signals): New arg DUMPING so that we can be more accurate
6932 about whether we're dumping. Caller changed.
6933 Treat thread-specific signals differently from process-general signals.
6934 Block all signals while handling fatal error; that's safer.
6935 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6937 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6938 Ignore SIGPIPE unless batch.
6939 (emacs_backtrace): Output backtrace for the appropriate thread,
6940 which is not necessarily the main thread.
6941 * syssignal.h: Include <stdbool.h>.
6942 (emacs_raise): New macro.
6943 * xterm.c (x_connection_signal): Remove; no longer needed
6944 now that we use sigaction.
6945 (x_connection_closed): No need to mess with sigmask now.
6946 (x_initialize): No need to reset SIGPIPE handler here, since
6947 init_signals does this for us now.
6949 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6951 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6952 background rect may be larger (Bug#12245).
6954 2012-09-23 Chong Yidong <cyd@gnu.org>
6956 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6958 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6960 * .gdbinit: Just stop at fatal_error_backtrace.
6961 See Stefan Monnier's request in
6962 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6963 Remove no-longer-used query of system type.
6965 2012-09-22 Chong Yidong <cyd@gnu.org>
6967 * search.c (Freplace_match): Doc fix (Bug#12325).
6969 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6971 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6972 (Fline_end_position): Doc fix.
6974 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6976 2012-09-22 Chong Yidong <cyd@gnu.org>
6978 * dispextern.h (struct image_type): Add new slot, storing a type
6979 initialization function.
6981 * image.c (define_image_type): Call the image initializer function
6982 if it is defined. Arguments and return value changed.
6983 (valid_image_p, make_image): Callers changed.
6984 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6985 (gif_type, imagemagick_type, svg_type, gs_type):
6986 Add initialization functions.
6987 (Finit_image_library): Call lookup_image_type.
6988 (CHECK_LIB_AVAILABLE): Macro deleted.
6989 (lookup_image_type): Call define_image_type here, rather than via
6990 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6991 (syms_of_image): Move define_image_type calls for xbm_type and
6992 pbm_type to lookup_image_type.
6994 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6996 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6997 'idle_timers' from here ...
6998 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6999 lists, to avoid infloops when the timer does something stupid,
7000 like reinvoke itself with the same or smaller time-out.
7003 2012-09-22 Martin Rudalics <rudalics@gmx.at>
7005 * window.c (Fsplit_window_internal): Handle only Qt value of
7006 Vwindow_combination_limit separately.
7007 (Qtemp_buffer_resize): New symbol.
7008 (Vwindow_combination_limit): New default value.
7011 2012-09-22 Eli Zaretskii <eliz@gnu.org>
7013 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
7014 the new overlay string. (Bug#10159)
7016 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
7018 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
7019 or that fprintf is async-signal-safe. POSIX doesn't require
7022 2012-09-22 Chong Yidong <cyd@gnu.org>
7024 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
7027 2012-09-22 Kenichi Handa <handa@gnu.org>
7029 * composite.c (composition_reseat_it): Handle the case that a
7030 grapheme cluster is not covered by a single font (Bug#12352).
7032 2012-09-21 Chong Yidong <cyd@gnu.org>
7034 * image.c (define_image_type): Avoid adding duplicate types to
7035 image_types (Bug#12463). Suggested by Jörg Walter.
7037 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7039 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
7040 (print_load_command_name): Add case LC_DATA_IN_CODE.
7041 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
7043 2012-09-21 Glenn Morris <rgm@gnu.org>
7045 * eval.c (Frun_hook_with_args_until_success)
7046 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
7048 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
7050 * fileio.c (Ffile_selinux_context): Only call freecon when
7051 lgetfilecon succeeded.
7052 (Fset_file_selinux_context): Likewise. (Bug#12444)
7054 2012-09-21 Eli Zaretskii <eliz@gnu.org>
7056 * xdisp.c (try_window_reusing_current_matrix): Under bidi
7057 reordering, locate the cursor by calling set_cursor_from_row; if
7058 that fails, clear the desired glyph matrix before returning a
7059 failure indication to the caller. Fixes leaving garbled display
7060 when fast scrolling with a down-key. (Bug#12403)
7061 (compute_stop_pos_backwards): Fix a typo that caused crashes while
7062 scrolling through multibyte text.
7064 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
7066 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
7067 calling mark_vectorlike since that's the one that marks the window.
7068 (mark_discard_killed_buffers): Mark the final cdr.
7069 * window.h (struct window): Move prev/next_buffers to the
7070 non-standard fields.
7071 * window.c (make_window): Initialize prev/next_buffers manually.
7073 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
7075 Omit unused arg EXPECTED from socket hooks.
7076 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
7077 * nsterm.m (ns_term_init):
7078 * termhooks.h (struct terminal.read_socket_hook):
7079 * w32inevt.c (w32_console_read_socket):
7080 * w32term.c (w32_read_socket):
7081 * xterm.c (XTread_socket):
7082 Omit unused arg EXPECTED. All callers changed.
7083 (store_user_signal_events): Return void, not int, since callers no
7084 longer care about the return value. All uses changed.
7086 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
7088 * w32gui.h (XParseGeometry): Do not declare.
7090 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
7092 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
7093 Ignore 'expected'. See Eli Zaretskii in
7094 <http://bugs.gnu.org/12471#8> (last line).
7096 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
7097 (XParseGeometry): Now static. Substitute extremal values for
7098 values that are out of range.
7100 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
7102 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
7104 * nsfns.m (XParseGeometry): Remove.
7105 (Fx_create_frame): Call x_set_offset to correctly interpret
7106 top_pos in geometry.
7108 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
7109 (Fx_parse_geometry): If there is a space in string, call
7110 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
7112 2012-09-17 Eli Zaretskii <eliz@gnu.org>
7114 * search.c (scan_buffer): Use character positions in calls to
7115 region_cache_forward and region_cache_backward, not byte
7116 positions. (Bug#12196)
7118 * w32term.c (w32_read_socket): Set pending_signals to 1, like
7119 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
7121 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
7122 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
7123 emacs_blocked_malloc, now deleted.
7125 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
7127 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
7128 The workaround was for improving performance on Solaris 2.4, but
7129 is getting in the way now. Emacs will still work if someone is
7130 still running Solaris 2.4 in a museum somewhere; Sun dropped
7131 support for Solaris 2.4 in 2003.
7132 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
7133 * process.c (create_process) [HAVE_WORKING_VFORK]:
7134 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
7135 since Emacs no longer uses vfork on that platform.
7137 2012-09-17 Glenn Morris <rgm@gnu.org>
7139 * emacs.c: Use COPYRIGHT.
7141 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
7143 Remove configure's --without-sync-input option (Bug#12450).
7144 When auditing signal-handling in preparation for cleaning it up,
7145 I found that SYNC_INPUT has race conditions and would be a real
7146 pain to fix. Since it's an undocumented and deprecated
7147 configure-time option, now seems like a good time to remove it.
7148 Also see <http://bugs.gnu.org/11080#16>.
7149 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
7150 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
7151 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7152 (malloc_hysteresis):
7153 (check_depth) [XMALLOC_OVERRUN_CHECK]:
7154 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
7155 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
7156 (dont_register_blocks, bytes_used_when_reconsidered)
7157 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
7158 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
7159 [!SYSTEM_MALLOC && !SYNC_INPUT]:
7160 Remove. All uses removed.
7161 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
7162 implementation, one that depends on whether the new macro
7163 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
7165 * atimer.c (run_timers, handle_alarm_signal):
7166 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
7167 (handle_async_input, process_pending_signals)
7168 (handle_input_available_signal, init_keyboard):
7169 * nsterm.m (ns_read_socket):
7170 * process.c (wait_reading_process_output):
7171 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
7172 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
7174 * xterm.c (XTread_socket):
7176 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
7177 * eval.c (handling_signal): Remove. All uses removed.
7178 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
7179 All uses replaced with the SYNC_INPUT version.
7180 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
7182 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7185 * font.c (Ffont_shape_gstring): Remove unused local.
7187 2012-09-16 Glenn Morris <rgm@gnu.org>
7189 * Makefile.in (clean): No longer run nextstep's clean.
7191 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
7193 (ns-app): Move here from ns.mk, and simplify.
7194 (clean): Simplify nextstep entry.
7195 * ns.mk: Remove file.
7197 2012-09-17 Kenichi Handa <handa@gnu.org>
7199 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
7200 not covert the last few charactes.
7202 2012-09-16 Kenichi Handa <handa@gnu.org>
7204 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
7205 here, but just check the validity of glyphs in the glyph-string.
7207 2012-09-16 Martin Rudalics <rudalics@gmx.at>
7209 * window.c (Fwindow_parameter, Fset_window_parameter):
7210 Accept any window as argument (Bug#12452).
7212 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
7214 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
7215 to ns_term_init to avoid memory leak.
7217 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
7218 explicit retain/release.
7219 (ns_term_init): Only allow one display. Initialize outerpool and
7222 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7224 Port _setjmp fix to POSIXish hosts as well as Microsoft.
7225 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
7226 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
7227 the Microsoft problem in a different way, by altering ../nt/config.nt.
7229 2012-09-15 Eli Zaretskii <eliz@gnu.org>
7244 * w16select.c: Remove inclusion of setjmp.h, as it is now included
7245 by lisp.h. This completes removal of setjmp.h inclusion
7246 erroneously announced in the previous commit. (Bug#12446)
7248 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
7251 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
7252 not defined as a macro. The latter happens on MS-Windows.
7255 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7257 Port better to POSIX hosts lacking _setjmp (Bug#12446).
7258 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
7259 Some instances of '#include <setjmp.h>' removed, if the
7260 only reason for the instance was because "lisp.h" was included.
7261 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
7262 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
7263 and _longjmp with the new symbols. Emacs already uses _setjmp if
7264 available, so this change affects only POSIXish hosts that have
7265 sigsetjmp but not _setjmp, such as some versions of Solaris and
7266 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
7267 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
7268 (png_load_body) [HAVE_PNG]:
7269 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
7270 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
7271 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
7272 since PNG requires jmp_buf. This is the only exception to the
7273 general rule that we now use sys_setjmp and sys_longjmp.
7274 This exception is OK since this code does not change the signal
7275 mask or longjmp out of a signal handler.
7277 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
7279 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7280 Include "syssignal.h", for 'main_thread'.
7282 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
7284 Avoid out-of-range marker position (Bug#12426).
7285 * insdel.c (replace_range, replace_range_2):
7286 Adjust markers before overlays, as suggested by comments.
7287 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
7288 Remove redundant check before calling offset_intervals.
7290 2012-09-14 Martin Rudalics <rudalics@gmx.at>
7292 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
7293 current buffer (Bug#12387).
7295 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
7297 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
7299 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7301 Use a more backwards-compatible timer format (Bug#12430).
7302 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
7303 vector element, not from the 4th, since PSECS is now at the end.
7304 (Fcurrent_idle_time): Doc fix.
7306 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
7308 Function to mark objects and remove killed buffers at once.
7309 * alloc.c (discard_killed_buffers): Rename to ...
7310 (mark_discard_killed buffers) ... new name. Add marking
7311 of remaining objects. Fix comment. Adjust users.
7312 (mark_object): Do not touch frame buffer lists here.
7313 * frame.c (delete_frame): Reset frame buffer lists here.
7315 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7317 Better workaround for GNOME bug when --enable-gcc-warnings.
7318 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
7319 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
7320 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
7322 Simplify SIGIO usage (Bug#12408).
7323 The code that dealt with SIGIO was crufty and confusing, e.g., it
7324 played tricks like "#undef SIGIO" but these tricks were not used
7325 consistently. Simplify mostly by not #undeffing standard symbols,
7326 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
7327 or not as we please) rather than "defined SIGIO" (standard symbol
7328 that we probably shouldn't #undef).
7329 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
7330 Modules that need it can include it.
7331 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
7332 * dispextern.h (ignore_sigio): New decl.
7333 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
7334 unconditionally, since it's now a no-op if !USABLE_SIGIO.
7335 * emacs.c (shut_down_emacs):
7336 * keyboard.c (kbd_buffer_store_event_hold):
7337 Use ignore_sigio rather than invoking 'signal' directly.
7338 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
7340 (FIONREAD, SIGIO): Do not #undef.
7341 (tty_read_avail_input): Use #error rather than a syntax error.
7342 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
7343 for I_PIPE, used by SETUP_SLAVE_PTY.
7344 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
7345 * sysdep.c (croak): Remove; no longer needed. This bit of
7346 temporary code, with Fred N. Fish's comment that it's temporary,
7347 has been in Emacs since at least 1992!
7348 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
7349 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
7350 * syssignal.h (croak): Remove decl.
7351 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
7352 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
7353 now that we're termios-only.
7354 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
7355 * term.c (dissociate_if_controlling_tty): Use #error rather than
7358 Work around GCC and GNOME bugs when --enable-gcc-warnings.
7359 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
7360 to work around GNOME bug 683906.
7361 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
7362 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
7363 This works around GCC bug 54561.
7365 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7367 More fixes for 'volatile' and setjmp/longjmp.
7368 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
7369 * image.c (struct png_load_context) [HAVE_PNG]: New type.
7370 (png_load_body) [HAVE_PNG]:
7371 (jpeg_load_body) [HAVE_JPEG]:
7372 New function, with most of the old parent function's body.
7373 (png_load) [HAVE_PNG]:
7374 (jpeg_load) [HAVE_JPEG]:
7375 Invoke the new function, to avoid longjmp munging our locals.
7376 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
7377 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
7378 longjmp is passed 2, as the C standard doesn't guarantee this.
7379 Instead, store the failure code into mgr->failure_code.
7381 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7383 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
7384 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
7385 (syms_of_keyboard): Remove support for unread-command-char.
7387 2012-09-12 Eli Zaretskii <eliz@gnu.org>
7389 * w32proc.c (sys_kill): If PID is our process ID and the signal is
7390 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
7391 violation. (Bug#12426)
7393 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7395 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
7397 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7399 * eval.c: Add `inhibit-debugger'.
7400 (Qinhibit_debugger): New symbol.
7401 (call_debugger): Bind it instead of Qdebug_on_error.
7402 (maybe_call_debugger): Test Vinhibit_debugger.
7403 (syms_of_eval): Define inhibit-debugger.
7404 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
7405 (syms_of_xdisp): Remove inhibit-debug-on-message.
7407 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7409 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
7410 If a nonvolatile local variable is written before a _longjmp to
7411 the frame containing the variable, and is read after the _longjmp,
7412 the value read is indeterminate. Some local variables of type
7413 'struct handler' and 'struct catchtag' are used in this way, so
7414 mark each of their slots as volatile if the slot can be set before
7415 _longjmp and read afterwards.
7416 * lisp.h (struct handler): var and chosen_clause are now volatile.
7417 (struct catchtag): val, next, and pdlcount are now volatile.
7419 * bidi.c (bidi_push_it, bidi_pop_it):
7420 * fns.c (copy_hash_table):
7421 * image.c (define_image_type):
7422 * keyboard.c (kbd_buffer_store_event_hold):
7423 * process.c (Fprocess_send_eof):
7424 * xfaces.c (x_create_gc) [HAVE_NS]:
7425 * xgselect.c (xg_select):
7426 Prefer assignment to memcpy when either will do.
7428 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
7429 Use pointer-to-a-pointer to simplify and avoid a NILP check each
7430 time an item is removed. No need to mark this function 'inline';
7431 the compiler knows better than we do.
7433 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
7435 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
7436 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
7437 to change_frame_size (Bug#12388).
7438 (windowDidResize:): Pass YES to updateFrameSize.
7440 * nsterm.h: Add delay parameter to updateFrameSize.
7442 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7444 Discard killed buffers from deleted window and frame objects.
7445 This reduces an amount of references to killed buffers and
7446 helps GC to reclaim them faster.
7447 * alloc.c (discard_killed_buffers): New function.
7448 (mark_object): Use it for deleted windows and frames.
7449 (mark_object): If symbol's value is set up for a killed buffer
7450 or deleted frame, restore its global binding.
7451 * data.c (swap_in_global_binding): Add GC notice.
7452 (swap_in_symval_forwarding): Use convenient set_blv_where.
7453 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
7454 * window.h: ... to here.
7456 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7458 Convenient macro to check whether the buffer is live.
7459 * buffer.h (BUFFER_LIVE_P): New macro.
7460 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
7461 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
7463 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7465 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
7466 composition cases (Bug#12364).
7468 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
7469 overhang of succeeding glyphs overlapping box cursor.
7471 * w32term.c (x_draw_glyph_string): Likewise.
7473 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7475 Simplify, document, and port floating-point (Bug#12381).
7476 The porting part of this patch fixes bugs on non-IEEE platforms
7477 with frexp, ldexp, logb.
7478 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
7480 * floatfns.c: Simplify discussion of functions that Emacs doesn't
7481 support, by removing commented-out code and briefly listing the
7482 C89 functions excluded. The commented-out stuff was confusing
7483 maintenance, e.g., we thought we needed cbrt but it was commented out.
7484 (logb): Remove decl; no longer needed.
7485 (isfinite): New macro, if not already supplied.
7486 (isnan): Don't replace any existing macro.
7487 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
7488 are present on all C89 platforms.
7489 (Ffrexp): Do not special-case zero, as frexp does the right thing
7491 (Flogb): Do not use logb, as it doesn't have the desired meaning
7492 on hosts that use non-base-2 floating point. Instead, stick with
7493 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
7494 frexp, to avoid getting an unspecified result.
7496 * xdisp.c (Qinhibit_debug_on_message): Now static.
7498 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
7500 * nsterm.m (ns_update_begin): Set clip path to whole view by using
7501 NSBezierPath (Bug#12131).
7503 2012-09-10 Chong Yidong <cyd@gnu.org>
7505 * fns.c (Fdelq, Fdelete): Doc fix.
7507 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
7509 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
7510 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
7512 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
7514 * lisp.h (make_lisp_ptr): New macro to replace XSET.
7515 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
7518 2012-09-09 Eli Zaretskii <eliz@gnu.org>
7520 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
7521 left fringe if the window has a left margin. This avoids leaving
7522 traces of the cursor because its leftmost pixel is not drawn over.
7524 * dispnew.c (update_window_line): When the left margin area of a
7525 screen line is updated, set the redraw_fringe_bitmaps_p flag of
7526 that screen line. (Bug#12277)
7528 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
7530 Assume C89 or later for math functions (Bug#12381).
7531 This simplifies the code, and makes it a bit smaller and faster,
7532 and (most important) makes it easier to clean up signal handling
7533 since we can stop worring about floating-point exceptions in
7534 library code. That was a problem before C89, but the problem
7535 went away many years ago on all practical Emacs targets.
7536 * data.c, image.c, lread.c, print.c:
7537 Don't include <math.h>; no longer needed.
7538 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
7539 might be autoconfigured, as that never happens.
7541 * doprnt.c (DBL_MAX_10_EXP):
7542 * print.c (DBL_DIG):
7543 Remove. C89 or later always defines these.
7544 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
7545 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
7546 (arith_error, domain_error, domain_error2):
7547 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
7548 no longer needed -- we simply return what C returns. All uses removed.
7549 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
7551 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
7552 Remove. All uses expanded, as these macros are no longer used
7553 more than once and are now more trouble than they're worth.
7554 (Ftan): Use tan, not sin / cos.
7555 (Flogb): Assume C89 frexp.
7556 (fmod_float): Assume C89 fmod.
7557 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
7558 (init_floatfns): Remove. All uses removed.
7560 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7562 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
7563 compositeToPoint for OSX < 10.6 (Bug#12390).
7565 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
7567 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
7568 This produces more-accurate results.
7570 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7572 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
7573 changes (Bug#12088).
7575 2012-09-08 Chong Yidong <cyd@gnu.org>
7577 * syntax.c (Fstring_to_syntax): Doc fix.
7579 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7581 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
7582 in the internal border.
7583 (x_set_window_size): Remove static variables and their usage.
7584 (ns_redraw_scroll_bars): Fix NSTRACE arg.
7585 (ns_after_update_window_line, ns_draw_fringe_bitmap):
7586 Remove fringe/internal border adjustment (Bug#11052).
7587 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
7588 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
7589 (ns_fix_rect_ibw): Remove.
7590 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
7591 (ns_dumpglyphs_box_or_relief): Ditto.
7592 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
7594 (ns_dumpglyphs_image): Ditto.
7595 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
7597 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
7598 their usage. Add fringe_extended_p and its use as in other terms.
7599 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
7600 scroll bar was removed.
7601 (updateFrameSize): New function.
7602 (windowDidResize): Move code to updateFrameSize and call it.
7604 * nsterm.h (EmacsView): Add updateFrameSize.
7606 2012-09-07 Chong Yidong <cyd@gnu.org>
7608 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
7610 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
7612 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7614 More signal-handler cleanup (Bug#12327).
7615 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
7616 Problem introduced when merging patches. Noted by Eli Zaretskii in
7617 <http://bugs.gnu.org/12327#67>.
7618 * floatfns.c: Comment fix.
7619 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
7620 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
7621 and anyway the declaration is harmless even if SIGDANGER is not defined.
7622 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
7623 defined BROKEN_FIONREAD). systty.h formerly did this, but other
7624 source files not surprisingly expected syssignal.h to define, or
7625 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7626 Include <sys/ioctl.h>, for FIONREAD.
7627 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7628 This eliminates a problem whereby other files mysteriously had
7629 to include "syssignal.h" before including "systty.h" if they
7630 wanted to use "#ifdef SIGIO".
7632 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7634 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7636 * w32.c (sigemptyset): Empty the set.
7637 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7639 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7641 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7643 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7644 (mark_object): Likewise for frame objects.
7646 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7648 * syssignal.h (handle_on_main_thread): Always declare,
7649 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7650 This ports to platforms without HAVE_PTHREAD.
7652 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7654 Signal-handler cleanup (Bug#12327).
7655 Emacs's signal handlers were written in the old 4.2BSD style with
7656 sigblock and sigmask and so forth, and this led to some
7657 inefficiencies and confusion. Rewrite these to use
7658 pthread_sigmask etc. without copying signal sets around. Also,
7659 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7660 'signal', and instead use functions that do not attempt to take
7661 over the system name space. This patch causes Emacs's text
7662 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7663 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7664 Do not include <signal.h> or "syssignal.h", as these
7665 modules do not use signals.
7666 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7667 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7668 Do not include <signal.h>, as "syssignal.h" does that for us now.
7669 * atimer.c (sigmask_atimers): New function.
7670 (block_atimers, unblock_atimers): New functions,
7671 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7673 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7674 no longer needed here.
7675 * emacs.c (main): Inspect existing signal handler with sigaction,
7676 so that there's no need to block and unblock SIGHUP.
7677 * sysdep.c (struct save_signal): New member 'action', replacing
7678 old member 'handler'.
7679 (save_signal_handlers, restore_signal_handlers):
7680 Use sigaction instead of 'signal' to save and restore.
7681 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7682 New function. All users of 'signal' modified to use set_sighandler
7683 if they're writeonly, and to use sys_signal if they're read+write.
7684 (emacs_sigaction_init, forwarded_signal): New functions.
7685 (sys_signal): Remove. All uses replaced by calls to sigaction
7686 and emacs_sigaction_init, or by direct calls to 'signal'.
7687 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7688 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7689 all uses replaced by pthread_sigmask etc. calls.
7690 * syssignal.h: Include <signal.h>.
7691 (emacs_sigaction_init, forwarded_signal): New decls.
7692 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7693 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7694 (sigmask, sys_sigmask): Remove; no longer needed.
7695 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7696 (sigblock, sigunblock, sigfree):
7697 (sigsetmask) [!defined sigsetmask]:
7698 Remove. All uses replaced by pthread_sigmask.
7699 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7700 no longer need to be replaced, and its typical old uses
7701 are now done via emacs_sigaction_init and sigaction.
7702 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7703 (sys_sigdel): Remove; unused.
7704 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7706 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7708 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7709 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7711 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7713 Explicitly mark buffer_defaults and buffer_local_symbols.
7714 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7715 mark_local_symbols here.
7716 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7717 since special buffers aren't marked here any more.
7718 (allocate_buffer): Chain new buffer with all_buffers here...
7719 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7721 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7722 (syms_of_buffer): Remove staticpro of the above.
7723 (init_buffer_once): Set names for buffer_defaults and
7724 buffer_local_symbols.
7726 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7728 Use bool for booleans in font-related modules.
7729 * font.c (font_intern_prop, font_style_to_value)
7730 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7731 (generate_otf_features, font_check_otf_features, font_check_otf)
7732 (font_match_p, font_list_entities, font_at):
7733 * fontset.c (fontset_id_valid_p, reorder_font_vector
7734 (fontset_find_font, Fset_fontset_font)
7735 (face_suitable_for_char_p) [0]:
7736 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7737 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7738 (m17n_flt_initialized, ftfont_shape_by_flt):
7739 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7740 * nsfont.m (nsfont_draw):
7741 * w32font.c (w32font_draw):
7742 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7743 Use bool for booleans.
7744 * font.h: Adjust to above API changes.
7745 (struct font, struct font_driver, struct font_driver_list):
7746 Use bool for booleans.
7747 (struct font): Remove useless member encoding_type.
7749 * fontset.c, xftfont.c: Omit unnecessary static decls.
7751 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7753 * alloc.c (mark_object): Revert window marking code
7754 since it's unsafe for the Fset_window_configuration.
7756 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7758 Fix race conditions with signal handlers and errno (Bug#12327).
7759 Be more systematic about preserving errno whenever a signal
7760 handler returns, even if it's not in the main thread. Do this by
7761 renaming signal handlers to distinguish between signal delivery
7762 and signal handling. All uses changed.
7763 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7764 * data.c (deliver_arith_signal): Rename from arith_error.
7765 * dispnew.c (deliver_window_change_signal): Rename from
7766 window_change_signal.
7767 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7768 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7769 * keyboard.c (deliver_input_available_signal): Rename from
7770 input_available_signal.
7771 (deliver_user_signal): Rename from handle_user_signal.
7772 (deliver_interrupt_signal): Rename from interrupt_signal.
7773 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7774 (deliver_child_signal): Rename from sigchld_handler.
7775 * atimer.c (handle_alarm_signal):
7776 * data.c (handle_arith_signal):
7777 * dispnew.c (handle_window_change_signal):
7778 * emacs.c (handle_fatal_signal, handle_danger_signal):
7779 * keyboard.c (handle_input_available_signal):
7780 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7781 * process.c (handle_pipe_signal, handle_child_signal):
7782 New functions, with the actual signal-handling code taken from the
7783 original respective signal handlers, sans the sporadic attempts to
7784 preserve errno, since that's now done by handle_on_main_thread.
7785 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7786 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7787 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7789 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7790 Move initialization of main_thread to sysdep.c's init_signals.
7791 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7792 our usage, and simplifies the mainline code.
7793 (record_child_status_change): New static function, as a helper
7794 for handle_child_signal, and with most of the old child handler's
7796 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7797 (handle_child_signal): Use the above.
7798 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7799 Moved here from emacs.c.
7800 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7801 code moved here from emacs.c's main function.
7802 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7803 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7804 This lets callers save and restore errno properly.
7806 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7808 Remove redundant or unused things here and there.
7809 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7810 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7811 * editfns.c (Fcompare_buffer_substrings): Likewise.
7812 * frame.h (struct terminal, struct font_driver_list):
7813 Remove redundant declarations.
7814 * window.h (Qleft, Qright): Likewise.
7816 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7818 Do not mark objects from deleted buffers, windows and frames.
7819 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7820 (mark_object): Likewise for windows and frames.
7822 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7824 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7825 buffer_defaults and buffer_local_symbols as valid objects.
7826 Return special value to denote them.
7828 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7830 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7831 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7832 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7833 (file_name_absolute_p, Fsubstitute_in_file_name):
7834 (check_executable, check_writable, Ffile_accessible_directory_p)
7835 (Fset_file_selinux_context, Fdefault_file_modes)
7836 (Finsert_file_contents, choose_write_coding_system)
7837 (Fwrite_region, build_annotations, a_write, e_write)
7839 * filelock.c (boot_time_initialized, get_boot_time)
7840 (get_boot_time_1, lock_file_1, within_one_second):
7841 * floatfns.c (in_float):
7842 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7843 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7844 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7845 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7846 * window.c (compare_window_configurations):
7847 Use bool for booleans.
7848 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7849 (Fdefault_file_modes): Now mode_t, not int, for modes.
7850 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7851 (internal_delete_file): Now returns void, not a (boolean) int,
7852 since nobody was looking at the return value.
7853 * lisp.h, window.h: Adjust to above API changes.
7855 * xdisp.c (set_message): Simplify and reindent last change.
7857 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7859 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7861 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7863 * eval.c (call_debugger): Make the function non-static so that we
7864 can call it from set_message.
7866 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7867 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7869 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7871 Give more-useful info on a fatal error (Bug#12328).
7872 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7873 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7874 of doing the work ourselves.
7875 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7876 do most of the work.
7877 (fatal_error_backtrace): New function, taken from the guts
7878 of the old fatal_error_signal, but with a new option to output
7880 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7881 info about the signal than just its number.
7882 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7883 * sysdep.c: Include <execinfo.h>
7884 (emacs_backtrace): New function, taken partly from the previous
7885 code of the 'die' function.
7886 (emacs_abort): Call fatal_error_backtrace rather than abort.
7888 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7890 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7891 eager (load-time) macro-expansion.
7892 * lisp.mk (lisp): Add macroexp.
7894 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7896 Simplify redefinition of 'abort' (Bug#12316).
7897 Do not try to redefine the 'abort' function. Instead, redo
7898 the code so that it calls 'emacs_abort' rather than 'abort'.
7899 This removes the need for the NO_ABORT configure-time macro
7900 and makes it easier to change the abort code to do a backtrace.
7901 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7902 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7903 Remove; sysdep.c's emacs_abort now takes its place.
7904 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7905 'abort' changed to use 'emacs_abort'.
7906 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7907 (abort) [!defined abort]: Rename to ...
7908 (emacs_abort): ... new name.
7909 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7910 the place of the old 'abort' in emacs.c.
7911 * w32.c, w32fns.c (abort): Do not #undef.
7912 * w32.c (emacs_abort): Rename from w32_abort.
7914 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7916 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7917 offsets[j].dv, since the y axis of the screen coordinates points
7918 down, while the y axis of the font definition coordinates points
7919 up. This fixes display of Arabic diacritics such as KASRA and
7920 KASRATAN. (Bug#11860)
7922 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7924 Be more systematic about _setjmp vs setjmp.
7925 * alloc.c (test_setjmp, mark_stack):
7926 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7927 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7928 (png_load, my_error_exit, jpeg_load):
7929 * process.c (send_process_trap, send_process):
7930 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7931 The underscored versions are up to 30x faster on some hosts.
7932 Formerly, the code used setjmp+longjmp sometimes and
7933 _setjmp+_longjmp at other times, with no particular reason to
7934 prefer setjmp+longjmp.
7936 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7938 Fix minor problem found by static checking.
7939 * buffer.c (Fdelete_all_overlays): Return nil.
7941 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7943 * buffer.c (Fdelete_all_overlays): New function.
7945 2012-09-03 Chong Yidong <cyd@gnu.org>
7947 * gtkutil.c: Add extern decl for Qxft.
7949 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
7951 * emacs.c, eval.c: Use bool for boolean.
7952 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

7960 * process.c (read_process_output, exec_sentinel):
7961 Use bool for booleans.
7962 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
7963 All callers changed.
7964 * eval.c (interactive_p): Omit always-true boolean argument
7965 EXCLUDE_SUBRS_P. All callers changed.
7966 * dispextern.h, lisp.h: Reflect above API changes.
7967 * firstfile.c (dummy): Use the address of 'main', whose signature
7968 won't change, instead of the address of 'initialize', whose
7969 signature just changed from int to bool.
7970 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7971 * msdos.c (fatal_error_in_progress): ... from here.
7972 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7974 (redisplay_internal, unwind_redisplay): Simply clear
7975 REDISPLAYING_P when unwinding, instead of saving its previous,
7976 always-false value and then restoring it.
7978 Clean up some extern decls.
7979 Mostly, this hoists extern decls out of .c files and into .h files.
7980 That way, we're more likely to catch errors if the interfaces change.
7981 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7982 declare xg_mark_data.
7983 * dispextern.h (x_frame_parm_handlers):
7985 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
7986 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
7987 (Qultra_bold, Qoblique, Qitalic):
7988 Move extern decl here from .c file.
7989 * alloc.c (xg_mark_data) [USE_GTK]:

7998 * process.c (QCfamily, QCfilter):
7999 * widget.c (free_frame_faces):
8000 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
8001 * xfont.c (x_clear_errors):
8002 * xterm.c (x_frame_parm_handlers):
8003 Remove now-redundant extern decls.
8004 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
8005 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
8007 * xfaces.c: Remove unnecessary static decls.
8008 * xterm.c (updating_frame): Remove decl of nonexistent object.
8010 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
8011 when building globals.h, as the objects that are not built on
8012 this host are not needed to compile C files on this host.
8014 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
8016 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

8029 (format_time_string, general_insert_function)
8030 (make_buffer_string, make_buffer_string_both)
8031 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
8032 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

8043 (set_intervals_multibyte_1, set_intervals_multibyte):
8044 * keyboard.c (decode_timer):
8045 Use bool for boolean.
8046 * intervals.h, lisp.h, systime.h: Reflect above API changes.

8049 2012-09-02 Chong Yidong <cyd@gnu.org>
8051 * keymap.c (push_key_description): Print M-TAB as C-M-i
8054 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
8056 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
8057 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

8062 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
8064 2012-09-01 Eli Zaretskii <eliz@gnu.org>
8066 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
8067 more than one grapheme cluster passed to the shaper: compute the
8068 offset adjustment values separately for each cluster. (Bug#11860)
8070 * image.c: Restore mistakenly removed inclusion of w32.h. Without
8071 it, GCC doesn't see prototypes of w32_delayed_load, and complains
8072 about implicit conversions from integer to pointer.
8074 2012-09-01 Daniel Colascione <dancol@dancol.org>
8076 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
8077 system used too early.
8079 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
8081 Better seed support for (random).

8110 * process.c: Include TERM_HEADER instead of listing all possible
8111 window-system headers.
8113 * nsterm.h: Remove declarations now in frame.h.
8114 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
8116 * menu.c: Include TERM_HEADER instead of listing all possible
8117 window-system headers.
8119 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
8122 * keyboard.c: Include TERM_HEADER instead of listing all possible
8123 window-system headers.
8125 * image.c: Include TERM_HEADER instead of listing all possible
8126 window-system headers. Declare Vlibrary_cache when compiling for
8129 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
8130 window system declarations.
8132 * frame.h: Move common functions here: set_frame_menubar,
8133 x_set_window_size, x_sync, x_get_focus_frame,
8134 x_set_mouse_position, x_set_mouse_pixel_position,
8135 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
8136 x_char_width, x_char_height, x_pixel_width, x_pixel_height,

8156 the current window system; include in list of objects to link into
8159 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8161 Remove mark_ttys function and fix tty_display_info initialization.
8162 * lisp.h (mark_ttys): Remove prototype.
8163 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
8164 to mark_ttys because all possible values of 'top_frame' slot are
8165 the frames which are reachable from Vframe_list.
8166 * term.c (mark_ttys): Remove.
8167 (init_tty): Safely initialize 'top_frame' slot with Qnil.
8169 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8171 Change struct frame bitfields from unsigned char to unsigned.
8172 * frame.h (struct frame): Change type of 'display_preempted',
8173 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
8174 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
8175 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
8176 bitfields from unsigned char to unsigned.
8178 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8180 Remove unused member of struct x_output and struct w32_output.

8184 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
8186 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
8187 does not become zero (Bug#12234).
8189 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
8191 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
8192 for GCC 4.7.1 x86-64.
8194 2012-08-30 Glenn Morris <rgm@gnu.org>
8196 * lread.c (init_lread): For out-of-tree builds, only add the
8197 source directory's site-lisp dir to the load-path if it exists,
8198 consistent with in-tree builds. (Bug#12302)
8200 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
8202 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
8203 button_values to NULL. Call setStykeMask so dialogs get a close button.
8204 (windowShouldClose:): Set window_closed.
8205 (dealloc): New member, free button_values.
8206 (process_dialog:): Make member function. Remove window argument,
8207 replace window with self. Count buttons and allocate and store values
8209 (addButton:value:row:): value is int with the name tag. Call setTag
8210 with tag. Remove return self, declare return value as void.
8211 (addString:row:): Remove return self, declare return value as void.
8212 (addSplit): Remove return self, declare return value as void.
8213 (clicked:): Remove return self, declare return value as void.
8214 Set dialog_return to button_values[seltag]. Code formatting change.
8215 (initFromContents:isQuestion:): Adjust call to process_dialog.
8216 Code formatting change.
8217 (timeout_handler:): Set timer_fired to YES.
8218 (runDialogAt:): Set timer_fired to NO.
8219 Handle click on close button as quit.
8221 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
8222 Add window_closed and button_values. Add void as return value for
8223 add(Button|String|Split). addButton takes int instead of Lisp_Object.
8224 Add process_dialog as new member.
8226 2012-08-28 Eli Zaretskii <eliz@gnu.org>
8228 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
8229 is not one of the heaps we manage. (Bug#12242)
8231 2012-08-28 Glenn Morris <rgm@gnu.org>
8233 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
8235 2012-08-28 Martin Rudalics <rudalics@gmx.at>
8237 * window.c (Fset_window_configuration): Remove handling of

8244 * buffer.c (Fset_buffer_major_mode): Signal an error
8245 if the buffer is dead.
8246 (Fother_buffer, other_buffer_safely): Remove redundant
8249 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
8251 Always use set_buffer_if_live to restore original buffer at unwind.
8252 * buffer.h (record_unwind_current_buffer): New function.
8253 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
8254 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
8255 * undo.c, window.c: Adjust users.
8256 * buffer.c (set_buffer_if_live): Fix comment.
8258 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
8260 Fix usage of set_buffer_internal.
8261 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
8262 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
8263 * coding.c (decode_coding): Omit redundant test.
8264 * fileio.c (decide_coding_unwind): Likewise.
8265 * fns.c (secure_hash): Likewise.
8266 * insdel.c (modify_region): Likewise.
8267 * keyboard.c (command_loop_1): Likewise.
8268 * print.c (PRINTFINISH): Likewise.
8269 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
8271 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

8291 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
8292 and remove last int (actually boolean) argument, which was always 0.
8293 All callers changed.
8294 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
8295 * dispextern.h (struct composition_it): Use bool for boolean.
8296 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
8297 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
8298 * dired.c (file_name_completion):
8299 Use bool for boolean. (This was missed in an earlier change.)
8301 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8303 * window.c (Fset_window_configuration): Revert first part of
8306 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
8308 * nsterm.h (NSPanel): New class variable dialog_return.
8310 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
8311 Initialize dialog_return.
8312 (windowShouldClose:): Use stop instead of stopModalWithCode.
8313 (clicked:): Ditto, and also set dialog_return (Bug#12258).
8314 (timeout_handler:): Use stop instead of abortModal. Send a dummy
8316 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

8360 * fileio.c (Finsert_file_contents):
8361 Use bool for booleans.
8362 * coding.h, lisp.h: Reflect above API changes.
8363 * coding.c: Remove unnecessary static function decls.
8364 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
8365 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
8366 not a boolean 'int', since callers never look at the return value.
8367 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
8368 * coding.h (decoding_buffer_size, encoding_buffer_size)
8369 (emacs_mule_string_char): Remove unused extern decls.
8370 (struct iso_2022_spec, struct coding_system):
8371 Use 'unsigned int : 1' for boolean fields, since there's more than one.
8372 (struct emacs_mule_spec): Remove unused field 'full_support'.
8373 All initializations removed.
8374 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
8376 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8378 Fix spare memory change (Bug#12286).
8379 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
8380 (valid_lisp_object_p): Likewise.
8382 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8384 * window.c (Fset_window_configuration): Record any window's old
8385 buffer if it's replaced (see Bug#8789). If the new current
8386 buffer doesn't appear in the selected window, go to its old
8389 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8391 Special MEM_TYPE_SPARE to denote reserved memory.
8392 * alloc.c (enum mem_type): New memory type.
8393 (refill_memory_reserve): Use new type for spare memory.
8394 This prevents live_cons_p and live_string_p from incorrect
8395 detection of uninitialized objects from spare memory as live.
8397 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
8400 * Makefile.in (.PHONY): versioclean -> versionclean.
8402 Remove unused external symbols.
8403 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
8404 * window.c (Qwindow_valid_p, decode_valid_window):
8405 Now static, not extern.
8406 * data.c (Qinterval): Remove; unused.
8407 (syms_of_data): Do not define 'interval'.
8408 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
8409 * window.h (decode_valid_window):
8412 * character.c, charset.c, chartab.c: Use bool for booleans.

8422 (char_table_set_range, optimize_sub_char_table)
8423 (map_sub_char_table):
8424 Use bool for boolean.
8425 * character.c (str_to_unibyte): Omit last boolean argument; it was
8426 always 0. All callers changed.
8427 * character.h, charset.h: Adjust to match previous changes.
8428 * character.h (char_printable_p): Remove decl of nonexistent function.
8429 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
8430 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
8431 are all boolean, so make them single-bit bitfields.
8433 * lisp.h (ASET): Remove attempt to detect side effects.
8434 It was meant to be temporary and it often doesn't work,
8435 because when IDX has side effects the behavior of IDX==IDX
8436 is undefined. See Stefan Monnier in
8437 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
8439 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
8441 * lisp.h (functionp): New function (extracted from Ffunctionp).
8442 (FUNCTIONP): Use it.
8443 * eval.c (Ffunctionp): Use it.
8445 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8447 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
8448 as that's faster and simpler than static storage. Don't bother
8449 with the g_main_context_query overhead if g_main_context_pending
8450 says no events are pending.
8451 (gfds, gfds_size): Remove these static vars.
8452 (xgselect_initialize): Remove; no longer needed.
8453 All uses and decls removed.
8455 * emacs.c (fatal_error_signal_hook): Remove.
8456 All uses removed. This leftover from old code was always 0.
8458 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
8459 * casefiddle.c (casify_object, casify_region):
8460 * casetab.c (set_case_table):
8461 * category.c, category.h (word_boundary_p):
8462 * category.h (CHAR_HAS_CATEGORY):
8463 Use bool for booleans, instead of int.
8465 2012-08-25 Eli Zaretskii <eliz@gnu.org>
8467 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
8469 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8471 On assertion failure, print backtrace if available.
8472 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
8473 (die) [ENABLE_CHECKING]: Print a backtrace if available.
8474 * Makefile.in (LIB_EXECINFO): New macro.
8477 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
8478 * bytecode.c (exec_byte_code):
8479 * callint.c (check_mark, Fcall_interactively):
8480 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
8481 (getenv_internal, sync_process_alive, call_process_exited):
8482 * lisp.h (USE_SAFE_ALLOCA):
8483 Use bool for booleans, instead of int.
8484 * lisp.h, process.h: Adjust prototypes to match above changes.
8485 * callint.c (Fcall_interactively): Don't assume the mark's
8486 offset fits in 'int'.
8488 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
8490 * buffer.c, buffer.h: Use bool for boolean.
8491 * buffer.c (reset_buffer_local_variables)

8497 (mmap_enlarge, mmap_set_vars):
8498 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
8499 Use bool for booleans, instead of int.
8500 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
8501 since the 1-or-0 return value is always ignored anyway.
8502 (mmap_initialized_p):
8503 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
8504 * buffer.h, lisp.h: Adjust prototypes to match above changes.
8506 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8508 * bidi.c: Use bool for boolean.
8509 This is a bit more readable, and makes the text segment of bidi.o
8510 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
8511 Presumably it's faster too.
8512 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
8514 (bidi_cache_find_level_change, bidi_cache_iterator_state)
8515 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)

8517 (bidi_explicit_dir_char, bidi_level_of_next_char)
8518 (bidi_find_other_level_edge, bidi_move_to_visually_next):
8519 Use bool for booleans, instead of int.
8520 * dispextern.h (bidi_init_it, bidi_paragraph_init)
8521 (bidi_unshelve_cache): Adjust decls to match code.
8523 2012-08-23 Martin Rudalics <rudalics@gmx.at>
8525 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
8528 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8530 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
8531 * atimer.h: Include <stdbool.h>.
8533 2012-08-22 Dan Nicolaescu <dann@gnu.org>
8535 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
8536 compile time tests instead of run time tests on systems that do
8538 (FRAME_MAC_P): Remove leftover from deleted code.
8539 * frame.c (syms_of_frame): Remove leftover from deleted code.
8541 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
8543 * nsterm.m (insertText:): Don't clear modifiers if code is space.
8545 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
8547 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
8548 Otherwise, the compiler complains about (A?B:C) where B is void
8549 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
8550 (fontset_add): Return void, for FONTSET_ADD.
8552 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8554 * alloc.c: Use bool for booleans.
8555 (gc_in_progress, abort_on_gc)
8556 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8557 (dont_register_blocks) [GC_MALLOC_CHECK]:
8558 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
8559 (check_string_bytes, make_specified_string, memory_full)
8560 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
8561 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
8562 (mark_stack, valid_pointer_p, make_pure_string)
8563 (Fgarbage_collect, survives_gc_p, gc_sweep):
8564 Use bool for booleans, instead of int.
8565 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8566 Remove unused local.
8567 * alloc.c (PURE_POINTER_P):
8568 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
8569 * editfns.c (Fformat):
8570 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
8572 * fns.c (sweep_weak_table):
8573 * lisp.h (suppress_checking, push_message, survives_gc_p)
8574 (make_pure_string, gc_in_progress, abort_on_gc):
8575 * lread.c (readchar, read1):
8576 * print.c (Fprin1_to_string):
8577 * xdisp.c (push_message):
8578 Use bool for booleans affected directly or indirectly by
8581 Make recently-introduced setters macros.
8582 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
8583 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
8584 (set_fontset_default, set_fontset_fallback): Rename from their
8585 upper-case counterparts, and make them functions rather than macros.
8586 This is more consistent with the other recently-introduced setters.
8587 These don't need to be inline, since they're local.
8589 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
8591 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
8592 the loop (Bug#12247).
8594 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8596 * lisp.h (vcopy): Use memcpy rather than our own loop.
8597 This fixes a performance regression introduced by the recent
8598 addition of vcopy. This means 'vcopy' will need to be modified
8599 for a copying collector, but that's OK. Also, tighten the
8600 checking in the assertion.
8602 2012-08-21 Eli Zaretskii <eliz@gnu.org>
8604 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
8605 components for RTL text (Bug#11860). Adjust X-OFFSET of each
8606 non-base glyph for the width of the base character, according to
8607 what x_draw_composite_glyph_string_foreground expects.
8608 Generate WADJUST value according to composition_gstring_width's
8609 expectations, to produce correct width of the composed character.
8610 Reverse the sign of the DU offset produced by ScriptPlace.
8612 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8614 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
8616 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8618 Avoid direct writes to contents member of struct Lisp_Vector.
8619 * lisp.h (vcopy): New function to copy data into vector.
8620 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
8621 * fns.c (Ffillarray): Use ASET.
8622 * keyboard.c (timer_check_2): Use AREF and ASET.
8623 (append_tool_bar_item, Frecent_keys): Use vcopy.
8624 * lread.c (read_vector): Use ASET.
8625 * msdos.c (Frecent_doskeys): Use vcopy.
8626 * xface.c (Finternal_copy_lisp_face): Use vcopy.
8627 (Finternal_merge_in_global_face): Use ASET and vcopy.
8628 * xfont.c (xfont_list_pattern): Likewise.
8630 2012-08-21 Martin Rudalics <rudalics@gmx.at>
8632 * window.c (Fwindow_point): For the selected window always return
8633 the position of its buffer's point.
8634 (Fset_window_point): For the selected window always go in its
8635 buffer to the specified position.
8637 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8639 Setter macros for fontsets.
8640 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
8641 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
8642 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8645 2012-08-20 Glenn Morris <rgm@gnu.org>
8647 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8648 Don't assume that `ln -f' works.
8650 2012-08-20 Eli Zaretskii <eliz@gnu.org>
8652 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8653 and later about non-assignments with no effect. See discussion at

8677 Inline setter functions for hash table members.
8678 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8679 (set_hash_hash, set_hash_index): Rename with _slot suffix.

8694 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8696 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8698 Rely on <config.h> + <unistd.h> to declare 'environ',
8699 as gnulib does this if the system doesn't.
8700 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8701 Remove declaration. MS-Windows declares it on stdlib.h which is

8704 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.

8735 * chartab.c, lisp.h (char_table_set, char_table_set_range):
8736 Return void, not Lisp_Object. Otherwise, the compiler
8737 complains about (A?B:C) where B is void and C is Lisp_Object
8738 when compiling CHAR_TABLE_SET, due to the recent change to
8739 the API of sub_char_table_set_contents.

9569 2012-08-04 Eli Zaretskii <eliz@gnu.org>
9571 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
9572 * w32.c (init_environment): Change the default values of many
9573 environment variables in dflt_envvars[] to NULL, to avoid pushing
9574 them into environment when they were not already defined.
9575 Remove the code that deletes site-lisp subdirectories from the default
9576 value of EMACSLOADPATH, as it is no longer needed.
9577 (check_windows_init_file): Now external, not static.
9578 Use Vload_path as is, without adding anything, as this function is now
9579 called when Vload_path is already set up.
9581 * w32.h (check_windows_init_file): Add prototype.
9583 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
9584 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
9585 compatibility with Posix platforms.
9586 (main): Move the call to check_windows_init_file to here from
9588 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
9589 any, in the DEFALT argument into the root of the Emacs build or
9590 installation tree, as appropriate.
9592 * callproc.c (init_callproc_1): Call decode_env_path instead of
9593 doing its equivalent by hand.
9594 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
9595 the code that sets Vexec_path run on MS-Windows.
9597 * lread.c (init_lread): Add comments to #ifdef's.
9599 * msdos.c (dos_set_window_size, IT_update_begin)
9600 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
9601 instead of direct references.

9607 Now constants, not macros.
9609 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
9611 Remove unnecessary casts involving pointers.
9612 These casts are no longer needed now that we assume C89 or later,
9613 since they involve casting to or from void *.
9614 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
9615 (make_pure_float, make_pure_vector):
9616 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

9625 (x_get_window_property, x_get_window_property_as_lisp_data):
9626 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
9627 Remove unnecessary pointer casts.
9628 * alloc.c (record_xmalloc): New function.
9629 * lisp.h (record_xmalloc): New decl.
9630 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
9631 more like a function. This is because the pointer cast is not
9632 needed. All uses changed.
9633 * print.c (print_string, print_error_message): Avoid length recalc.
9635 Improve fix for macroexp crash with debugging (Bug#12118).
9636 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
9637 ARRAY_MARK_FLAG when checking subscripts, because ASET is
9638 not supposed to be invoked from the garbage collector.
9639 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
9640 (gc_aset): New function, which is like ASET but can be
9641 used in the garbage collector.
9642 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

9652 <g_b_init_create_symbolic_link>: New static flags.
9653 (globals_of_w32): Initialize them to zero.
9654 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
9655 (map_w32_filename): Improve commentary. Simplify switch.
9656 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
9657 headers (most versions of MinGW w32api don't).
9658 (get_security_info, create_symbolic_link)
9659 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
9661 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
9662 in the argument file name.

9665 (sys_rename): Diagnose renaming of a symlink when the user doesn't
9666 have the required privileges.
9667 (get_file_security_desc_by_name): Rename from
9668 get_file_security_desc.
9669 (stat_worker): New function, with most of the guts of 'stat', and
9670 with addition of handling of symlinks and support for 'lstat'.
9671 If possible, get file's attributes and security information by
9672 handle, not by name. Produce S_IFLNK bit for symlinks, when
9673 called from 'lstat'.
9674 (stat, lstat): New functions, call 'stat_worker'.
9675 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9676 symlinks when the underlying filesystem supports them.
9678 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
9680 Fix macroexp crash on Windows with debugging (Bug#12118).
9681 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9682 checking subscripts; problem introduced with the recent
9683 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9684 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9685 since it's used in non-static inline functions now.
9687 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9688 Don't assume buffer size fits in 'int'. Remove unused local.

9705 * category.c (CATEGORY_INLINE):
9706 * character.c (CHARACTER_INLINE):
9707 * charset.c (CHARSET_INLINE):
9708 * composite.c (COMPOSITE_INLINE):
9709 * dispnew.c (DISPEXTERN_INLINE):
9710 * sysdep.c (SYSTIME_INLINE):
9711 Define to EXTERN_INLINE, so that the corresponding functions
9712 are compiled into code.
9713 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
9714 (INLINE_HEADER_END): New macros.
9715 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9735 hard-coding the path separator.
9737 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9739 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9740 This how ASET and AREF are supposed to work, and makes
9741 it easier to think about future improvements. See
9742 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
9743 * charset.h (set_charset_attr): New function.

10013 (MANY, UNEVALLED, FLOAT_TO_STRING_BUFSIZE, MAX_ALLOCA):
10014 Now constants, for GDB. They need not be macros.

10017 (CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):
10018 Move to after the definition of struct Lisp_Char_Table,
10019 since the former now needs that type defined.

10045 These macros are confusing and no longer need to be defined, as
10046 the enum values now suffice. All uses replaced with definiens.

10121 (w32_read_console_input): New inline function, calls either
10122 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
10123 w32_console_unicode_input.
10124 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
10125 (w32_kbd_patch_key, key_event): Use the codepage returned by

10158 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
10159 enumeration constants, as PURE and HEAP are too general, and clash
10160 with other headers and sources, such as gmalloc.c and the
10161 MS-Windows system headers. All users changed.
10163 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10165 Revert last save_excursion_save and save_excursion_restore changes.
10166 * alloc.c, editfns.c, marker.c, lisp.h: Revert.
10167 Lots of crashes reported by Chong Yidong <cyd@gnu.org>.
10169 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10171 Fix recently-introduced typos in Windows port.
10172 Reported by Martin Rudalics <rudalics@gmx.at>.

10174 * w32fns.c (syms_of_w32fns): Add missing parenthesis.
10176 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
10178 Improve GDB symbol export (Bug#12036).
10179 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
10180 arms of an 'if', not using conditional expressions; otherwise GDB
10181 complains about the types in the unevaluated arm when the argument
10182 is an integer literal.
10183 (xgetint): Simplify expression.
10184 * alloc.c (gdb_make_enums_visible): New constant. This ports to
10185 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
10186 Zaretskii in <http://bugs.gnu.org/12036#13>.
10187 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
10188 needed now that we have gdb_make_enums_visible.
10189 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
10190 (enum enum_USE_LSB_TAG):
10191 New enum types, packaging up enums that need to be exported to GDB.
10193 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10195 Utility function to make a list from specified amount of objects.
10196 * lisp.h (enum constype): New datatype.
10197 (listn): New prototype.
10198 * alloc.c (listn): New function.
10199 (Fmemory_use_count, syms_of_alloc): Use it.

10214 Fast save_excursion_save and save_excursion_restore.
10215 * lisp.h (struct Lisp_Excursion): New data type.
10216 (PVEC_EXCURSION): New pseudovector type.
10217 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
10218 to deal with it. Adjust comments.
10219 (init_marker, attach_marker): New prototype.
10220 (unchain_marker): Adjust prototype.
10221 * marker.c (attach_marker): Change to global.
10222 (init_marker): New function.

10232 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
10233 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
10234 emacs.c, as this is a more-suitable home. Had this been done earlier
10235 the fix for 12036 would have avoided some of the problems noted in
10236 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
10237 would have been more obvious.
10238 * emacs.c: Do not include <verify.h>; no longer needed.
10239 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
10240 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
10241 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10242 Remove; now done in lisp.h.
10243 * lisp.h (PUBLISH_TO_GDB): New macro.
10244 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
10245 (DATA_SEG_BITS): Use it.
10246 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
10247 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
10248 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
10249 not be usable in #if. This simplifies things.
10251 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
10253 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
10255 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
10257 Simplify export of symbols to GDB (Bug#12036).
10258 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
10259 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
10260 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
10261 Adjust to changes in lisp.h and emacs.c, by using
10262 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
10263 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
10264 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
10265 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
10266 instead of gdb_valbits.
10267 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
10268 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
10269 instead of gdb_array_mark_flag.
10270 (xboolvector): Get size from $->size, not $->header.size.
10271 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
10272 (xreload, hook-run, hookpost-run): Remove.
10273 * emacs.c: Include <verify.h>.
10274 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
10275 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
10277 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
10278 (gdb_USE_LSB_TAG): New enum constants.
10279 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10280 Also define these as enum constants, so they're visible to GDB.
10281 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
10282 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
10283 as constants, so they're visible to GDB.
10284 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
10285 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
10286 Now enum constants, not macros, so they're visible to GDB.
10287 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
10288 more convenient now. All uses changed.
10289 (VALMASK) [USE_LSB_TAG]: Also define in this case.
10290 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
10292 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
10294 Explicitly free restriction data that are not needed anymore.
10295 * editfns.c (save_restriction_restore): Free restriction data.
10297 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
10299 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
10300 add argument, tune behavior, and adjust all callers.
10302 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
10304 Use typedef for EMACS_INT, EMACS_UINT.
10305 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
10306 than macros. This simplifies debugging in the usual case, since
10307 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
10308 and it allows expressions involving EMACS_INT casts.
10309 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
10311 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
10313 * nsterm.m (ns_read_socket): Return early if there is a modal
10314 window (Bug#12043).
10316 2012-07-25 Martin Rudalics <rudalics@gmx.at>
10318 * frame.c (Fredirect_frame_focus): In doc-string don't mention
10319 that FOCUS-FRAME can be omitted.
10321 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
10323 Adjust buffer text indirection counters at the end of Fkill_buffer.
10324 * buffer.c (Fkill_buffer): Adjust indirection counters when the
10325 buffer is definitely dead. This should really fix an issue reported
10326 by Christoph Scholtes again. (Bug#12007).
10327 (init_buffer_once): Initialize indirection counters of
10328 buffer_defaults and buffer_local_symbols (for sanity and safety).
10330 2012-07-24 Eli Zaretskii <eliz@gnu.org>
10332 * xdisp.c (init_iterator): Don't compute dimensions of truncation
10333 and continuation glyphs on tooltip frames, leave them at zero.
10334 Avoids continued lines in tooltips. (Bug#11832)
10336 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
10338 Simplify copy_overlay.

10344 * print.c (print_object): Don't crash when a frame's name is nil
10345 or invalid. (Bug#12025)
10347 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
10348 it signals an error when a tooltip frame is being created.
10350 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
10352 Cleanup miscellaneous objects allocation and initialization.
10353 * alloc.c (allocate_misc): Change to static. Add argument to
10354 specify the subtype. Adjust comment and users.
10355 (build_overlay): New function.
10356 * buffer.c (copy_overlays, Fmake_overlay): Use it.
10357 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
10358 (allocate_misc): Remove prototype.
10359 (build_overlay): Add prototype.
10361 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
10363 Swap buffer text indirection counters in Fbuffer_swap_text.
10364 * buffer.c (Fbuffer_swap_text): Swap indirections too.
10365 This avoids crash reported by Christoph Scholtes at
10366 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
10368 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
10370 * nsmenu.m (Popdown_data): New struct.
10371 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
10373 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
10374 (initWithContentRect): Make imgView and contentView non-static
10375 and autorelease them. Also autorelease img and matrix (Bug#12005).
10376 (dealloc): Remove (Bug#12005).
10378 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
10380 Adjust consing_since_gc when objects are explicitly freed.
10381 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
10382 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
10383 (free_cons, free_misc): Subtract object size from consing_since_gc.
10385 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
10387 Simplify and cleanup markers positioning code.

11168 Prefer memcmp to strncmp when either will do.
11169 * nsterm.m: Include <ftoastr.h>.
11171 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
11172 Prefer snprintf to strncpy.
11173 * nsterm.m (ns_term_init):
11174 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
11175 * nsterm.m (ns_term_init):
11176 Avoid the need for strncpy, by using build_string or
11177 make_unibyte_string directly. Use dtoastr, not snprintf.
11178 * process.c (Fmake_network_process): Diagnose service names that
11179 are too long, rather than silently truncating them or creating

11250 We include usg5-4-common.h, which defines them both.
11252 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
11253 O_RDONLY already includes it).
11255 Stop ns builds setting the EMACSLOADPATH environment variable.
11256 * nsterm.m (ns_load_path): Rename from ns_init_paths.
11257 Now it does not set EMACSLOADPATH, just returns the load-path string.
11258 * nsterm.h: Update accordingly.
11259 * lread.c [HAVE_NS]: Include nsterm.h.
11260 (init_lread) [HAVE_NS]: Use ns_load_path.
11261 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
11263 2012-07-09 Glenn Morris <rgm@gnu.org>
11265 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
11266 since the included bsd-common.h does so.
11268 Stop ns builds setting the EMACSPATH environment variable.
11269 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
11270 (ns_init_paths): Do not set EMACSPATH.
11271 * nsterm.h (ns_exec_path): Add it.
11272 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
11275 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
11277 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
11279 * process.c (wait_reading_process_output): 'waitchannels' was unset
11280 when read_kbd || !NILP (wait_for_cell); fix this.
11282 Add GCC-style 'const' attribute to functions that can use it.
11283 * character.h (char_resolve_modifier_mask):
11284 * keyboard.h (make_ctrl_char):
11285 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
11286 (init_character_once, next_almost_prime, init_fns, init_image)
11287 (flush_pending_output, init_sound):
11288 * mem-limits.h (start_of_data):
11289 * menu.h (finish_menu_items):
11290 Add ATTRIBUTE_CONST.
11291 * emacs.c (DEFINE_DUMMY_FUNCTION):
11292 Declare the dummy function with ATTRIBUTE_CONST.
11293 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
11294 Add decls with ATTRIBUTE_CONST.
11296 Minor improvements to make_formatted_string.
11297 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
11298 where int is good enough, as vsprintf returns an int.
11299 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
11301 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
11303 Use make_formatted_string to avoid double length calculation.
11304 * lisp.h (make_formatted_string): New prototype.
11305 * alloc.c (make_formatted_string): New function.
11306 * buffer.c (Fgenerate_new_buffer_name): Use it.
11307 * dbusbind.c (syms_of_dbusbind): Likewise.

11319 2012-07-09 Glenn Morris <rgm@gnu.org>
11321 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
11322 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
11323 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

11325 * callproc.c [HAVE_NS]: Include nsterm.h.
11326 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
11328 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
11330 Move marker debugging code under MARKER_DEBUG.
11331 * marker.c (MARKER_DEBUG): Move marker debugging code under
11332 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
11333 for bootstrap with --enable-checking (~3x slowdown reported
11334 by Juanma Barranquero <lekktu@gmail.com>).
11335 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
11337 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
11339 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
11340 See <http://bugs.gnu.org/11825#29>.
11342 2012-07-08 Eli Zaretskii <eliz@gnu.org>
11344 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
11345 has no font, use the frame's font. (Bug#11813)
11346 (display_line): Add commentary about displaying truncation glyphs
11348 (produce_special_glyphs): Move here from term.c.
11350 * term.c (produce_special_glyphs): Move to xdisp.c.
11352 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
11355 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
11357 * xdisp.c (display_line): Avoid warning about implicit declaration
11360 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
11362 * lisp.h: Remove empty conditional.
11364 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11366 * lread.c (load_path_check): Now static.
11368 Fix some minor --with-ns problems found by static checking.
11369 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
11370 (x_set_font) [!HAVE_X_WINDOWS]:
11371 * image.c (xpm_load_image) [HAVE_NS]:
11372 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
11373 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
11374 Remove unused local.
11375 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
11376 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
11377 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
11378 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
11379 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
11380 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
11381 Fix pointer signedness problem.
11382 * xfaces.c (FRAME_X_FONT_TABLE):
11383 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
11385 2012-07-07 Glenn Morris <rgm@gnu.org>
11387 * lread.c (load_path_check): New function, split from init_lread.
11388 (init_lread): Reorganize. Motivation:
11389 If EMACSLOADPATH is set, check/warn about that rather than the
11390 defaults, which we are not going to use. Hence we can remove
11391 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
11392 Don't warn if site-lisp directories are missing.
11393 If not installed, start from a blank load-path, since
11394 PATH_LOADSEARCH refers to the eventual installation directories.
11396 2012-07-07 Eli Zaretskii <eliz@gnu.org>
11398 Support truncation and continuation glyphs on GUI frames, when
11399 fringes are disabled. (Bug#11832)
11400 * xdisp.c (init_iterator): Get dimensions of truncation and
11401 continuation glyphs even if on GUI frames.
11402 Adjust it->last_visible_x on GUI frames when the left or right fringes,
11403 or both, are absent.
11404 (start_display, move_it_in_display_line_to): Handle the case of a
11405 GUI frame without a fringe to display continuation or truncation
11407 (insert_left_trunc_glyphs): Support GUI frames: make sure
11408 truncation glyphs overwrite enough glyphs from the current line to
11409 have sufficient space in pixels.
11410 (display_line): Support truncation and continuation glyphs on GUI
11411 frames. If some spare pixels are left on the line after inserting
11412 the truncation glyphs, fill that space with a stretch glyph of a
11413 suitably computed width.
11415 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
11416 produce_glyphs, to support GUI sessions.
11418 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11420 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
11422 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
11424 Do not require float-time's arg to fit in time_t (Bug#11825).
11425 This works better on hosts where time_t is unsigned, and where
11426 float-time is applied to the (negative) difference between two times.
11427 * editfns.c (decode_time_components): Last arg is now double *,
11428 not int *, and means to store all the result as a double, without
11429 worrying about whether the seconds part fits in time_t.
11430 All callers changed.
11431 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
11432 All callers changed.
11433 (Ffloat_time): Do not fail merely because the specified time falls
11434 outside of time_t range.
11436 2012-07-07 Glenn Morris <rgm@gnu.org>
11438 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
11439 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
11440 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
11442 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
11444 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
11445 Update dependencies.
11447 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
11449 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

11452 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
11453 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
11454 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
11455 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
11456 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
11458 * xfont.c (compare_font_names): Redo to omit the need for casts.
11460 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
11462 * xfns.c (Fx_change_window_property): Doc fix.
11463 * w32fns.c (Fx_change_window_property): Doc fix.
11465 * w32fns.c (Fx_window_property): Accept the same arguments as the
11466 X Windows version. Doc fix.
11467 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
11469 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
11470 Eli Zaretskii <eliz@gnu.org>
11472 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
11473 Windows-specific code from nt/config.nt moved here.
11474 Obsolete settings removed.
11476 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11478 * process.c: Avoid unnecessary calls to gettime.
11479 (wait_reading_process_output): Don't get the time of day
11480 when gobbling data immediately and not waiting, as there's no need
11481 for it in that case. This removes a FIXME.
11483 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
11485 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
11486 is defined (Bug#11768).
11488 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11490 Fix marker debugging code.
11491 * marker.c (byte_char_debug_check): Do not perform the check
11492 if buffer is not multibyte.
11493 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11494 Call byte_char_debug_check with correct arguments.
11496 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11498 Compile marker debugging code only if ENABLE_CHECKING is defined.
11499 * marker.c (byte_char_debug_check, count_markers):
11500 Use only if ENABLE_CHECKING is defined.
11501 (byte_debug_flag): Remove.
11502 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11503 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
11505 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11507 Avoid code repetition in marker-related functions.
11508 * marker.c (attach_marker): New function.
11509 (Fset_marker, set_marker_restricted, set_marker_both)

11512 Consistently rename charno to charpos.
11513 (marker_position): Add eassert.
11514 (marker_byte_position): Convert to eassert.
11516 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

11530 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
11531 (save_restriction_save): Use build_marker.
11532 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
11533 * window.c (save_window_save): Likewise.
11535 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11537 Do not use Fdelete_overlay in delete_all_overlays
11538 to avoid redundant calls to unchain_overlay.

11540 (delete_all_overlays, Fdelete_overlay): Use it.
11541 * minibuf.c (get_minibuffer): Fix comment.
11543 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11545 Port to OpenBSD 5.1 amd64.
11546 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
11547 This is needed for OpenBSD, and should be harmless on all BSD systems.
11548 Also, include <sys/sysctl.h>, as it should be available on all
11549 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
11550 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
11551 use p_pid member, not kp_proc.pid.
11553 2012-07-06 Glenn Morris <rgm@gnu.org>
11555 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
11557 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11559 More xmalloc and related cleanup.
11560 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

11568 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
11570 Omit needless casts involving void * pointers and allocation.
11571 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
11572 as the former is more robust if P's type is changed.
11573 Prefer xzalloc to xmalloc + memset 0.
11574 Simplify malloc-or-realloc to realloc.
11575 Don't worry about xmalloc returning a null pointer.
11576 Prefer xstrdup to xmalloc + strcpy.
11577 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
11579 * keyboard.c (apply_modifiers_uncached): Prefer local array to

11584 * xdisp.c (display_line): Fix horizontal pixel coordinates when
11585 hscroll is larger than the line width. Fixes long and futile
11586 looping inside extend_face_to_end_of_line (on a TTY) producing
11587 glyphs that are not needed and thrown away.
11589 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
11591 * marker.c (set_marker_restricted_both): Simplify by using
11594 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

11605 followed by gtk_box_set_homogeneous (Bug#11768).
11606 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
11607 (update_theme_scrollbar_width, xg_create_scroll_bar):
11608 Use gtk_scrollbar_new (Bug#11768).

11610 (is_box_type): New function (Bug#11768).
11611 (xg_tool_item_stale_p): Call is_box_type.
11612 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
11613 with default display (Bug#11768).
11615 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11617 * xdisp.c (window_hscroll_limited): New function.
11618 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
11619 coordinates when window's hscroll is set to insanely large
11620 values. (Bug#11857)
11622 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

11687 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11689 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11691 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11692 This should be fixed in a better way; see Eli Zaretskii in
11693 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11694 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11696 * fileio.c (time_error_value): Rename from special_mtime.
11697 The old name's problems were noted by Eli Zaretskii in
11698 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11700 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11701 This variable's comment says Emacs needs at least one GDB-visible
11702 symbol of type enum pvec_type, to work around GDB problems.
11703 The symbol's value doesn't matter.
11705 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11706 that causes compilation to fail on pre-C99 compilers.
11708 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11710 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
11711 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
11713 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11715 * buffer.c (init_buffer_once): Fix initialization of
11716 headers for buffer_defaults and buffer_local_symbols.
11717 Reported by Juanma Barranquero <lekktu@gmail.com>.
11719 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11721 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
11722 * lisp.h (enum pvec_type): Use fewer bits.
11723 (PSEUDOVECTOR_SIZE_BITS): New constant.
11724 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
11725 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
11726 change in pvec_type.
11727 (PSEUDOVECTOR_TYPEP): New macro.
11728 (TYPED_PSEUDOVECTORP): Use it.
11729 * fns.c (internal_equal): Adapt code to extract pvectype.
11730 * emacs.c (gdb_pvec_type): Update type.
11731 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
11732 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
11733 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
11734 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11735 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11736 abusing vector->header.next.nbytes.
11737 (live_vector_p): Use PVEC_TYPE.
11738 (mark_object): Adapt code to extract pvectype. Use switch.
11740 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11742 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11743 Tighten new eassert a bit.
11745 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11747 Fix compilation with --enable-gcc-warnings and -O1
11748 optimization level.
11749 * doprnt.c (doprnt): Change type of tem to int, initialize
11750 to avoid compiler warning. Add eassert.
11751 * search.c (simple_search): Initialize match_byte to avoid
11752 compiler warning. Add eassert.
11754 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11756 Avoid weird behavior with large horizontal scrolls.
11757 Without this change, for example, large hscroll values would
11758 mess up Emacs's display on Fedora 15 x86, presumably due to
11759 overflows in int calculations in the display code.
11760 Also, if buffers had long lines, Emacs would freeze.
11761 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11762 (set_window_hscroll): New function, containing the old guts of
11763 Fset_window_hscroll. Return the clipped value.
11764 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11765 This avoids the need to check against PTRDIFF_MAX.
11767 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11769 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11771 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11773 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11775 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11776 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11777 since GCC 4.4.6 issues a bogus warning for them.
11779 Fix bugs in file timestamp newness comparisons.
11780 * fileio.c (Ffile_newer_than_file_p):
11781 * lread.c (Fload): Use full timestamp resolution of files,
11782 not just the 1-second resolution, so that files that are only
11783 slightly newer still count as newer.
11784 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11785 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11787 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11789 * fileio.c: Improve handling of file time marker. (Bug#11852)
11790 (special_mtime): New function.
11791 (Finsert_file_contents, Fverify_visited_file_modtime):
11792 Use it to set special mtime values consistently.
11794 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11796 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11797 marker for non-existing file. (Bug#11852)
11799 2012-07-03 Glenn Morris <rgm@gnu.org>
11801 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11802 and did not make it into globals.h).
11804 2012-07-03 Tom Tromey <tromey@redhat.com>
11806 * window.c (Fset_window_margins, Fset_window_fringes)
11807 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
11808 * textprop.c (Fprevious_property_change): No longer static.
11809 * syntax.c (Fsyntax_table_p): No longer static.
11810 * process.c (Fget_process, Fprocess_datagram_address): No longer
11812 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
11813 * keyboard.c (Fcommand_execute): No longer static.

11831 * intervals.h: Remove EXFUNs.
11832 * fontset.h: Remove EXFUN.
11833 * font.h: Remove EXFUNs.
11834 * dosfns.c (system_process_attributes): Remove EXFUN.
11835 * keymap.h: Remove EXFUNs.
11836 * lisp.h: Remove EXFUNs.
11837 * w32term.h: Remove EXFUNs.
11838 * window.h: Remove EXFUNs.
11839 * xsettings.h: Remove EXFUN.
11840 * xterm.h: Remove EXFUN.
11842 2012-07-03 Glenn Morris <rgm@gnu.org>
11844 * lisp.h (Frandom): Make it visible to C.
11845 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11846 buffer for invisible buffers. (Bug#1229)
11848 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11850 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11851 values which aren't power of 2.
11852 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11853 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11856 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11858 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11860 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11862 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11864 * alloc.c (allocate_vector_block): Remove redundant
11865 calls to mallopt if DOUG_LEA_MALLOC is defined.
11866 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11867 avoid calls to mallopt if zero_vector is returned.
11869 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11871 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11872 is enabled, avoid dereferencing NULL current_sblock if
11875 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11877 Cleanup basic buffer management.
11878 * buffer.h (struct buffer): Change layout to use generic vector
11879 marking code. Fix some comments. Change type of 'clip_changed'
11880 to bitfield. Remove unused #ifndef old.
11881 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11882 (GET_OVERLAYS_AT): Fix indentation.
11883 (for_each_per_buffer_object_at): New macro.
11884 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
11885 (Fbuffer_local_variables): Use it.
11886 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.

11888 struct buffer. Fix comment.
11889 (mark_overlay): New function.
11890 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11891 Lisp area of struct buffer.
11892 (mark_object): Use it. Adjust marking of misc objects
11893 and related comments.
11895 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11897 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11898 wrapper that is not needed because the wrapped code is a no-op (zero
11899 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11900 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11902 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11904 * alloc.c (mark_buffer): Simplify. Remove prototype.
11905 (mark_object): Add comment. Reorganize marking of vector-like
11906 objects. Use CHECK_LIVE for all vector-like objects except buffers
11907 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11908 Avoid redundant calls to mark_vectorlike for bool vectors.
11910 2012-06-30 Glenn Morris <rgm@gnu.org>
11912 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11914 * epaths.in (PATH_SITELOADSEARCH): New.
11915 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11916 This is rather than relying on --enable-locallisppath elements
11917 having "site-lisp" in their names. (Bug#10208#25, 11658)
11919 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11921 * w32proc.c (sys_select): Accept and ignore one more argument.
11923 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11925 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11926 (pselect) [!MS_DOS]: Redirect to sys_select.
11928 * sysdep.c: Don't include dos.h and dosfns.h.
11930 * process.c (sys_select):
11931 * msdos.c (sys_select): Accept one more argument and ignore it.
11933 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11934 adapt data types and code to that.
11937 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11938 which clashes with the gnulib function of the same name.
11940 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11942 * font.c (font_style_to_value, font_style_symbolic)
11943 (font_prop_validate_style): Add type checks for values in
11946 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11948 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11951 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11953 * xdisp.c (try_window_id): Undo last change.
11955 * w32.c (getwd): Adjust commentary about startup_dir.
11956 (init_environment): Always call sys_access, even in non-MSVC
11957 builds. Don't chdir to the directory of the Emacs executable.
11958 This undoes code from 1997 which was justified by the need to
11959 "avoid conflicts when removing and renaming directories". But its
11960 downside was that every relative file name was being interpreted
11961 relative to the directory of the Emacs executable, which can never
11962 be TRT. In particular, it broke sys_access when called with
11963 relative file names.
11964 (sys_access): Map GetLastError to errno.
11966 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11968 * window.h (struct window): Change type of 'fringes_outside_margins'
11969 to bitfield. Fix comment. Adjust users accordingly.
11970 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
11972 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11975 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11977 * gnutls.c (emacs_gnutls_handshake):
11978 Add QUIT to make the loop interruptible.
11980 2012-06-29 Glenn Morris <rgm@gnu.org>
11982 * charset.c (init_charset): Make lack of etc/charsets fatal.
11984 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11986 * editfns.c (region_limit): Fix type mismatch.
11988 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11990 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11991 undefined. Convert from xassert to eassert.
11992 * nsmenu.m: Convert from xassert to eassert.
11993 * nsterm.m: Likewise.
11995 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
11997 * editfns.c (region_limit): Clip to narrowing (bug#11770).
11999 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
12001 Avoid integer overflow on scroll-left and scroll-right.
12002 * window.c (HSCROLL_MAX): New macro.
12003 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
12004 overflow when requested scroll falls outside ptrdiff_t range.
12006 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
12008 * window.h (struct window): Change type of 'hscroll',
12009 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
12010 'last_modified' and 'last_overlay_modified' to EMACS_INT.
12011 Adjust users accordingly.
12012 * xdisp.c (try_cursor_movement): Replace type check with eassert.
12013 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
12014 from EMACS_INT to ptrdiff_t.
12015 (make_window): Omit redundant initialization.
12017 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
12019 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
12021 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

12033 enabled with --enable-checking=[all,glyphs] configure option.
12034 Fix GLYPH_DEBUG usage assuming that it may be undefined,
12035 adjust comments accordingly.

12037 undefined, adjust comments accordingly.

12084 * alloc.c (allocate_string_data): Remove dead code.

12156 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
12158 Use sprintf return value instead of invoking strlen on result.
12159 In the old days this wasn't portable, since some sprintf
12160 implementations returned char *. But they died out years ago and
12161 Emacs already assumes sprintf returns int.
12162 Similarly for float_to_string.
12163 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

12171 Use sprintf or float_to_string result to avoid need to call strlen.
12172 * data.c (Fnumber_to_string):

12209 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
12211 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

12216 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
12217 instead of truncating it to 63 (admittedly a generous limit).

12277 * keyboard.c (kbd_buffer_get_event):
12278 * process.c (Faccept_process_output):
12279 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
12280 This improves on the previous patch, which introduced a bug
12281 when time_t is unsigned and as wide as intmax_t.
12282 See <http://bugs.gnu.org/9000#51>.

12302 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
12304 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

12313 language ID in the event parameters.
12315 * w32term.c (w32_read_socket): Put the new keyboard codepage into
12316 event.code, not the obscure "character set ID".
12318 2012-06-23 Chong Yidong <cyd@gnu.org>

12347 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
12349 Support higher-resolution time stamps (Bug#9000).
12350 The time stamps are only nanosecond-resolution at the C level,
12351 since that's the best that any real-world system supports now.
12352 But they are picosecond-resolution at the Lisp level, as that's
12353 easy, and leaves room for future OS improvements.
12355 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
12358 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
12359 Don't get current time unless it's needed.
12361 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
12362 now provides it if it's absent.
12363 (start_atimer): Port to higher-res time stamps.
12364 Check for time stamp overflow. Don't get current time more
12365 often than is needed.
12367 * buffer.h (struct buffer): Buffer modtime now has high resolution.
12368 Include systime.h, not time.h.
12369 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
12371 * dired.c: Include stat-time.h.
12372 (Ffile-attributes): File times now have higher resolution.
12374 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
12375 (struct image): Timestamp now has higher resolution.
12377 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
12378 has at least microseconds now. All uses removed.
12379 (update_frame, update_single_window, update_window, update_frame_1)
12380 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
12381 (duration_to_sec_usec): Remove; no longer needed.
12383 * editfns.c (time_overflow): Now extern.
12384 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
12385 (float-time, Fformat_time_string, Fcurrent_time_string)
12386 (Fcurrent_time_zone): Accept and generate higher-resolution
12388 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
12389 (decode_time_components, lisp_seconds_argument): New functions.
12390 (make_time): Now static.
12391 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
12392 Report an error if the time is invalid, rather than having the caller
12395 * fileio.c: Include <stat-time.h>
12396 (Fcopy_file): Copy higher-resolution time stamps.
12397 Prefer to set the time stamp via a file descriptor if that works.
12398 (Fset_file_times, Finsert_file_contents, Fwrite_region)
12399 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
12400 (Fvisited_file_modtime, Fset_visited_file_modtime):
12401 Support higher-resolution time stamps.
12403 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
12405 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
12407 * image.c (prepare_image_for_display, clear_image_cache)
12408 (lookup_image): Port to higer-resolution time stamps.
12410 * keyboard.c (start_polling, bind_polling_period):
12411 Check for time stamp overflow.
12412 (read_char, kbd_buffer_get_event, timer_start_idle)
12413 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
12414 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
12415 Port to higher-resolution time stamps. Do not assume time_t is signed.
12416 (decode_timer): New function. Timers are now vectors of length 9,
12417 not 8, to accommodate the picosecond component.
12418 (timer_check_2): Use it.
12420 * nsterm.m (select_timeout, timeval_subtract): Remove.
12421 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
12422 as they're a bit more accurate and handle overflow better.
12423 (ns_select): Change prototype to be compatible with pselect.
12424 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
12425 * nsterm.h (ns_select): Adjust prototype.
12427 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
12428 us-resolution time stamps.
12429 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
12431 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
12433 * lisp.h (time_overflow): New decl.
12434 (wait_reading_process_output): First arg is now intmax_t, not int,
12435 to accommodate larger waits.
12437 * process.h (struct Lisp_Process.read_output_delay):
12438 Now counts nanoseconds, not microseconds.
12439 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
12441 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
12442 (wait_reading_process_output):
12443 Port to ns-resolution time stamps.
12444 (Faccept_process_output, wait_reading_process_output):
12445 Check for time stamp overflow. Do not assume time_t is signed.
12446 (select_wrapper): Remove; we now use pselect.
12447 (Fprocess_attributes): Now generates ns-resolution time stamps.
12449 * sysdep.c: Include utimens.h. Don't include utime.h
12450 or worry about struct utimbuf; gnulib does that for us now.
12451 (gettimeofday): Remove; gnulib provides a substitute.
12452 (make_timeval): New function.
12453 (set_file_times): Now sets ns-resolution time stamps.
12454 New arg FD; all uses changed.
12455 (time_from_jiffies, ltime_from_jiffies, get_up_time)
12456 (system_process_attributes):
12457 Now returns ns-resolution time stamp. All uses changed.
12458 Check for time stamp overflow.
12460 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
12461 provides a substitute now.
12463 * systime.h: Include timespec.h rather than sys/time.h and time.h,
12464 since it guarantees struct timespec.
12465 (EMACS_TIME): Now struct timespec, so that we can support
12466 ns-resolution time stamps.
12467 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
12468 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
12469 (EMACS_USECS): Remove.
12470 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
12471 so multiply the arg by 1000 before storing it.
12472 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
12474 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
12475 Port to ns-resolution time stamps.
12476 (EMACS_TIME_NEG_P): Remove; replaced by....
12477 (EMACS_TIME_SIGN): New macro.
12478 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
12479 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
12480 (set_file_times, make_time, lisp_time_argument): Adjust signature.
12481 (make_timeval, make_lisp_time, decode_time_components): New decls.
12482 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
12483 that it mishandled time_t overflow. You can't compare by subtracting!
12484 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
12485 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
12487 * term.c: Include <sys/time.h>.
12488 (timeval_to_Time): New function, for proper overflow wraparound.
12489 (term_mouse_position, term_mouse_click): Use it.
12491 * undo.c (record_first_change): Support higher-resolution time stamps
12492 in the undo buffer.
12493 (Fprimitive_undo): Use them when restoring time stamps.
12495 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
12496 (w32_get_internal_run_time):
12497 Port to higher-resolution Emacs time stamps.
12498 (ltime): Now accepts single 64-bit integer, as that's more convenient
12501 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
12503 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
12504 for compatibility with pselect. Support ns-resolution time stamps.
12506 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
12508 * xselect.c (wait_for_property_change, x_get_foreign_selection):
12509 Check for time stamp overflow, and support ns-resolution time stamps.
12511 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
12512 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
12513 (timeval_subtract): Remove; no longer needed.
12514 (XTflash, XTring_bell, x_wait_for_event):
12515 Port to ns-resolution time stamps. Don't assume time_t is signed.
12517 2012-06-22 Chong Yidong <cyd@gnu.org>

12521 2012-06-22 Eli Zaretskii <eliz@gnu.org>
12523 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
12524 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
12525 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
12526 staticidx goes up to 1597 out of 1600 = 0x640.)
12528 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
12530 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
12531 Otherwise, the umask might be mistakenly 0 while handling input signals.
12533 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

12542 access to `contents' member of Lisp_Vector objects with AREF and ASET
12545 2012-06-19 Chong Yidong <cyd@gnu.org>
12547 * frame.c (delete_frame): When selecting a frame on a different
12548 text terminal, do not alter the terminal's top-frame.
12550 * xdisp.c (format_mode_line_unwind_data): Record the target
12551 frame's selected window and its terminal's top-frame.
12552 (unwind_format_mode_line): Restore them.
12553 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
12555 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
12556 since tty frames can be explicitly named.
12557 (prepare_menu_bars): Likewise.
12559 * term.c (Ftty_top_frame): New function.
12561 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
12563 Port byte-code-meter to modern targets.
12564 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
12565 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
12566 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
12567 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
12568 (METER_1, METER_2): Simplify.
12570 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
12572 * data.c (Fdefalias): Return `symbol' (bug#11686).
12574 2012-06-18 Martin Rudalics <rudalics@gmx.at>
12576 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
12577 gets killed during executing of this function (Bug#11665).
12578 Try to always return Qt when the buffer has been actually killed.
12579 (Vkill_buffer_query_functions): In doc-string say that functions
12580 run by this hook should not change the current buffer.
12582 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
12584 Fix recently-introduced process.c problems found by static checking.
12585 * process.c (write_queue_push, write_queue_pop, send_process):
12586 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
12587 (write_queue_pop): Fix pointer signedness problem.
12588 (send_process): Remove unused local.
12590 2012-06-17 Chong Yidong <cyd@gnu.org>

12801 Use an inline function on all platforms when using the union type,

12947 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12948 would mishandle a string argument "Xc" if X was a multibyte

13003 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
13004 Convert pctcpu and pctmem to Lisp float properly.

13031 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
13032 Use 'float' consistently, rather than 'float' in most places
13033 and 'double' in a couple of places.
13035 2012-05-31 Eli Zaretskii <eliz@gnu.org>
13037 * xdisp.c (handle_stop): Detect whether we have overlay strings
13038 loaded by testing it->current.overlay_string_index to be

13052 maybe_unify_char, which was the cause of relocation of buffer text
13055 2012-05-31 Eli Zaretskii <eliz@gnu.org>
13057 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
13058 for the duration of call to load_charset, to avoid problems with
13059 callers of maybe_unify_char that access buffer text through C
13062 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
13063 decrement the inhibition flag, instead of just setting or
13066 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
13068 Remove obsolete '#define static' cruft.
13069 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
13070 This #undef was "temporary" in 2000; it is no longer needed
13071 now that '#define static' has gone away.
13072 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
13073 (gray_bitmap_bits): Remove; no longer needed.
13074 All uses replaced with definiens.
13075 * xterm.c: Include "bitmaps/gray.xbm".
13077 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
13079 Clean up __executable_start, monstartup when --enable-profiling.
13080 The following changes affect the code only when profiling.
13081 * dispnew.c (__executable_start): Rename from safe_bcopy.
13082 Define only on platforms that need it.
13083 * emacs.c: Include <sys/gmon.h> when profiling.
13084 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
13085 (__executable_start): Remove decl, since lisp.h does it now.
13086 (safe_bcopy): Remove decl; no longer has that name.
13087 (main): Coalesce #if into single bit of code, for simplicity.
13088 Cast pointers to uintptr_t, since standard libraries want integers
13090 * lisp.h (__executable_start): New decl.
13092 2012-05-31 Glenn Morris <rgm@gnu.org>
13094 * image.c (Fimagemagick_types): Doc fix.
13096 2012-05-30 Jim Meyering <meyering@redhat.com>
13098 * callproc.c (Fcall_process_region): Include directory component
13099 in mkstemp error message (Bug#11586).
13101 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
13103 * alloc.c, lisp.h (make_pure_vector): Now static.
13105 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
13107 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
13108 Move to byte-run.el.
13109 (Fautoload): Do the hash-doc more carefully.
13110 * data.c (Fdefalias): Purify definition, except for keymaps.
13111 (Qdefun): Move from eval.c.
13112 * lisp.h (Qdefun): Remove.
13113 * lread.c (read1): Tiny simplification.
13115 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
13117 Do not create empty overlays with the evaporate property (Bug#9642).
13118 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
13119 Bug#9642, but explicitly check that the buffer the overlay would
13120 be moved to is live and rearrange lines to make sure that errors
13121 will not put the overlay in an inconsistent state.
13122 (Fdelete_overlay): Cosmetics.
13124 2012-05-28 Eli Zaretskii <eliz@gnu.org>
13126 * w32term.c (my_bring_window_to_top): New function.
13127 (x_raise_frame): Use handle returned by DeferWindowPos, which
13128 could be different from the original one.
13129 Call my_bring_window_to_top instead of my_set_foreground_window.
13132 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
13133 by calling BringWindowToTop.

13138 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
13140 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
13141 This avoids undefined behavior that might cause the eassert
13142 to not catch an out-of-range value.
13144 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
13146 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
13147 Update dependencies.
13149 2012-05-27 Eli Zaretskii <eliz@gnu.org>
13151 * bidi.c (bidi_mirror_char): Fix last change.
13153 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
13155 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
13156 when referring to sectname field in printf format.
13158 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
13160 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
13161 Only r_alloc_inhibit_buffer_relocation needed to be added;
13162 the others were already declared.
13164 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
13165 before checking whether it's out of range. Put the check inside
13167 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
13169 2012-05-27 Ken Brown <kbrown@cornell.edu>
13171 * callproc.c (Fcall_process): Restore a line that was accidentally
13172 commented out in the 2011-02-13 change (bug#11547).
13174 2012-05-27 Eli Zaretskii <eliz@gnu.org>
13176 * lisp.h [REL_ALLOC]: Add prototypes for external functions
13177 defined on ralloc.c.
13179 * buffer.c [REL_ALLOC]: Remove prototypes of
13180 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
13181 they are now on lisp.h.
13183 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
13185 * search.c (search_buffer): Use it to inhibit relocation of buffer
13186 text while re_search_2 is doing its job, because re_search_2 is
13187 passed C pointers to buffer text. (Bug#11519)
13189 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
13190 Update value to 24.
13192 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
13193 state after an additional call to move_it_in_display_line_to, keep
13194 the values of it->max_ascent and it->max_descent found for the
13196 (pos_visible_p): Revert the comparison against bottom_y to what it
13197 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
13200 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13202 Fix coding-related core dumps with gcc -ftrapv.
13203 The code was computing A - B, where A and B are pointers, and B is
13204 random garbage. This can lead to core dumps on platforms that
13205 have special pointer registers, and it also leads to core dumps on
13206 x86-64 when compiled with gcc -ftrapv. The fix is to compute
13207 A - B only when B is initialized properly.
13208 * coding.c (coding_set_source, coding_set_destination): Return void.
13209 (coding_change_source, coding_change_destinations): New functions,
13210 with the old behaviors of coding_set_source and coding_set_destination.
13211 All callers that need an offset changed to use these new functions.
13213 2012-05-26 Glenn Morris <rgm@gnu.org>
13215 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
13217 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13219 Extend mouse support on W32 text-mode console.
13220 * xdisp.c (draw_row_with_mouse_face):
13221 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
13223 * w32console.c: Include window.h.
13224 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
13226 (initialize_w32_display): Initialize mouse-highlight data.
13228 * w32inevt.c: Include termchar.h and window.h.
13229 (do_mouse_event): Support mouse-autoselect-window. When the mouse
13230 moves, call note_mouse_highlight. If help_echo changed, call
13231 gen_help_event to produce help-echo message in the echo area.
13232 Call clear_mouse_face if mouse_face_hidden is set in the mouse
13235 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13237 * lread.c (read1): Simplify slightly to avoid an overflow warning
13238 with GCC 4.7.0 on x86-64.
13240 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13242 * bidi.c (bidi_mirror_char): Revert last change: an int is
13243 definitely wide enough here.
13245 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
13247 Fix integer width and related bugs (Bug#9874).
13248 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
13249 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
13250 (string_bytes, check_sblock, allocate_string_data):
13251 (compact_small_strings, Fmake_bool_vector, make_string)
13252 (make_unibyte_string, make_multibyte_string)
13253 (make_string_from_bytes, make_specified_string)
13254 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
13255 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
13257 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13258 (allocate_pseudovector):
13259 Use int, not EMACS_INT, where int is wide enough.
13260 (inhibit_garbage_collection, Fgarbage_collect):
13261 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13262 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
13263 int might not be wide enough.
13264 (bidi_cache_search, bidi_cache_find, bidi_init_it)
13265 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
13266 (bidi_at_paragraph_end, bidi_find_paragraph_start)
13267 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
13268 (bidi_level_of_next_char, bidi_move_to_visually_next):
13269 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13270 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
13271 (Fkill_buffer, Fset_buffer_major_mode)
13272 (advance_to_char_boundary, Fbuffer_swap_text)
13273 (Fset_buffer_multibyte, overlays_at, overlays_in)
13274 (overlay_touches_p, struct sortvec, record_overlay_string)
13275 (overlay_strings, recenter_overlay_lists)
13276 (adjust_overlays_for_insert, adjust_overlays_for_delete)
13277 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
13278 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
13279 (Foverlay_recenter, last_overlay_modification_hooks_used)
13280 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
13281 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13282 (validate_region): Omit unnecessary test for b <= e,
13283 since that's guaranteed by the previous test.
13284 (adjust_overlays_for_delete): Avoid pos + length overflow.
13285 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
13286 (report_overlay_modification):
13287 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13288 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
13289 Omit pointer cast, which isn't needed anyway, and doesn't work
13290 after the EMACS_INT -> ptrdiff_t change.
13291 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
13292 * buffer.h: Adjust decls to match defn changes elsewhere.
13293 (struct buffer_text, struct buffer):
13294 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13295 Use EMACS_INT, not int, where int might not be wide enough.
13296 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
13297 not int, to avoid needless 32-bit limit on 64-bit hosts.
13298 (exec_byte_code): Use tighter memory-full test, one that checks
13299 for alloca overflow. Don't compute the address of the object just
13300 before an array, as that's not portable. Use EMACS_INT, not
13301 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
13302 * callint.c (Fcall_interactively):
13303 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13304 * callproc.c (call_process_kill, Fcall_process):
13305 Don't assume pid_t fits into an Emacs fixnum.
13306 (call_process_cleanup, Fcall_process, child_setup):
13307 Don't assume pid_t fits into int.
13308 (call_process_cleanup, Fcall_process, delete_temp_file)
13309 (Fcall_process_region):
13310 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13311 (Fcall_process): Simplify handling of volatile integers.
13312 Use int, not EMACS_INT, where int will do.
13313 * casefiddle.c (casify_object, casify_region, operate_on_word)
13314 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
13315 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13316 (casify_object): Avoid integer overflow when overallocating buffer.
13317 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
13318 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
13319 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
13320 * category.h (CATEGORYP): Don't assume arg is nonnegative.
13321 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
13322 integers are now checked earlier. All uses replaced with XINT.
13324 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13325 For CCL_MapSingle, check that content and value are in int range.
13326 (ccl_driver, Fregister_code_conversion_map):
13327 Check that Vcode_version_map_vector is a vector.
13328 (resolve_symbol_ccl_program): Check that vector header is in range.
13329 Always copy the vector, so that we can check its contents reliably
13330 now rather than having to recheck each instruction as it's being
13331 executed. Check that vector words fit in 'int'.
13332 (ccl_get_compiled_code, Fregister_ccl_program)
13333 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
13334 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
13335 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
13336 contents are in range.
13337 (Fccl_execute_on_string): Check that status is in range.
13338 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
13339 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
13340 Accept and return EMACS_INT, not int, because callers can pass values
13341 out of 'int' range.
13342 (c_string_width, strwidth, lisp_string_width, chars_in_text)
13343 (multibyte_chars_in_text, parse_str_as_multibyte)

13345 (str_as_unibyte, str_to_unibyte, string_count_byte8)
13346 (string_escape_byte8, Fget_byte):
13347 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13348 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
13349 avoid mishandling large integers.
13350 * character.h: Adjust decls to match defn changes elsewhere.
13351 * charset.c (load_charset_map_from_file, find_charsets_in_text)
13352 (Ffind_charset_region):
13353 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13354 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
13355 (load_charset_map_from_vector, Fdefine_charset_internal):
13356 Don't assume fixnum fits in int.
13357 (load_charset_map_from_vector, Fmap_charset_chars):
13358 Remove now-unnecessary CHECK_NATNUMs.
13359 (Fdefine_charset_internal): Check ranges here, more carefully.
13360 Don't rely on undefined behavior with signed left shift overflow.
13361 Don't assume unsigned int fits into fixnum, or that fixnum fits
13362 into unsigned int. Don't require max_code to be a valid fixnum;
13363 that's not true for gb10830 4-byte on a 32-bit host. Allow
13364 invalid_code to be a cons, for the same reason. Require code_offset
13365 to be a character. Avoid int overflow if max_char is close
13367 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
13368 this is intended anyway and avoids some undefined behavior.
13369 (load_charset_map): Pass unsigned, not int, as 2nd arg of
13370 INDEX_TO_CODE_POINT, as that's what it expects.
13371 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
13372 * charset.h (DECODE_CHAR): Return int, not unsigned;
13373 this is what was intended anyway, and it avoids undefined behavior.
13374 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
13375 integer-overflow issues.
13376 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
13377 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
13378 where the argument is EMACS_INT, and this behavior is not intended.
13379 * chartab.c (Fmake_char_table, Fset_char_table_range)
13380 (uniprop_get_decoder, uniprop_get_encoder):
13381 Don't assume fixnum fits in int.
13382 * cmds.c (move_point): New function, that does the gist of
13383 Fforward_char and Fbackward_char, but does so while checking
13384 for integer overflow more accurately.
13385 (Fforward_char, Fbackward_char): Use it.
13386 (Fforward_line, Fend_of_line, internal_self_insert)
13387 (internal_self_insert):
13388 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13389 Fix a FIXME, by checking for integer overflow when calculating
13390 target_clm and actual_clm.

13422 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13423 (consume_chars): Rewrite to not calculate an address outside buffer.
13424 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
13425 Don't access memory outside of the args array.
13426 (Fdefine_coding_system_internal): Check for charset-id overflow.
13427 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
13428 result of ENCODE_CHAR.
13429 * coding.h: Adjust decls to match defn changes elsewhere.
13430 (struct coding_system):
13431 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

14126 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
14128 2012-05-19 Ken Brown <kbrown@cornell.edu>
14130 * xfns.c (x_in_use): Remove `static' qualifier.
14131 * xterm.h (x_in_use): Declare.
14132 * xgselect.c: Include xterm.h.
14133 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
14134 and `display_arg' (bug#9754).
14136 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
14138 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
14140 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
14141 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
14143 2012-05-18 Eli Zaretskii <eliz@gnu.org>
14145 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
14147 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
14148 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
14150 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
14151 reference to image_cache->refcount.
14152 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
14154 2012-05-17 Juri Linkov <juri@jurta.org>
14156 * search.c (Fword_search_regexp, Fword_search_backward)
14157 (Fword_search_forward, Fword_search_backward_lax)
14158 (Fword_search_forward_lax): Move functions to isearch.el
14159 (bug#10145, bug#11381).
14161 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
14163 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
14165 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
14167 * lread.c (init_obarray): Declare Qt and Qnil as special.
14169 2012-05-14 Glenn Morris <rgm@gnu.org>
14171 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
14172 Put "libexec" before "bin", for the sake of init_callproc_1.
14174 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14176 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
14178 * unexaix.c: Port to more-recent AIX compilers.
14179 (report_error, report_error_1, make_hdr, copy_sym)
14180 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
14181 Make arguments const char *, not char *, to avoid violations of C
14182 standard and to fix some AIX warnings reported by Gilles Pion.
14184 2012-05-14 Eli Zaretskii <eliz@gnu.org>
14186 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
14187 already have overlays loaded.
14188 (handle_single_display_spec): Before returning without displaying
14189 fringe bitmap, synchronize the bidi iterator with the main display
14190 iterator, by calling iterate_out_of_display_property.
14191 (iterate_out_of_display_property): Detect buffer iteration by
14192 testing that it->string is a Lisp string.
14193 (get_next_display_element): When the current object is exhausted,
14194 and there's something on it->stack, call set_iterator_to_next to
14195 proceed with what's on the stack, instead of returning zero.
14196 (set_iterator_to_next): If called at the end of a Lisp string,
14197 proceed to consider_string_end without incrementing string
14198 position. Don't increment display vector index past the end of
14199 the display vector. (Bug#11417)
14200 (pos_visible_p): Don't report a position visible when move_it_to
14201 stopped at the last line of window, which happens to be scanned
14202 backwards by the bidi iteration. (Bug#11464)
14204 2012-05-14 Eli Zaretskii <eliz@gnu.org>
14206 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
14207 and right-margin display specs even if the spec is invalid or we
14208 are on a TTY, and thus unable to display on the fringes.
14209 That's because the text with the property will not be displayed anyway,
14210 so we need to signal to the caller that this is a "replacing"
14211 display spec. This fixes display when the spec is invalid or we
14214 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14216 * unexaix.c (make_hdr): Fix typo in prototype.
14217 This bug broke the build on AIX. Problem reported by Gilles Pion.
14219 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
14221 * keyboard.c (kbd_buffer_get_event): Read special events also in
14222 batch mode. (Bug#11415)
14224 2012-05-12 Glenn Morris <rgm@gnu.org>
14226 * ns.mk: Update for ns_appbindir no longer having trailing "/".
14228 2012-05-12 Eli Zaretskii <eliz@gnu.org>
14230 * lisp.mk (lisp): Add newcomment.elc.
14232 2012-05-12 Glenn Morris <rgm@gnu.org>
14234 * Makefile.in (MKDIR_P): New, set by configure.
14235 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
14237 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
14239 Remove unused function hourglass_started.
14240 * dispextern.h (hourglass_started):
14241 * w32fns.c (hourglass_started):
14242 * xdisp.c (hourglass_started): Remove.
14244 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
14246 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
14247 Update dependencies.
14249 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
14251 * xgselect.c (xg_select): Put maxfds+1 into a var.
14252 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
14254 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
14256 2012-05-10 Dave Abrahams <dave@boostpro.com>
14258 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
14259 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
14261 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
14263 * dbusbind.c (xd_registered_buses): New internal Lisp object.
14264 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
14265 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
14266 Initialize xd_registered_buses.
14268 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
14270 Untag more efficiently if USE_LSB_TAG.
14271 This is based on a proposal by YAMAMOTO Mitsuharu in
14272 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
14273 For an admittedly artificial (nth 8000 longlist) benchmark on
14274 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
14275 Emacs's overall text size by 1%.
14276 * lisp.h (XUNTAG): New macro.
14277 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
14278 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
14279 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
14280 * eval.c (Fautoload):
14281 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
14282 * frame.h (XFRAME): Use XUNTAG.
14284 Port recent dbusbind.c changes to 32-bit --with-wide-int.
14285 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
14286 Remove unportable assumptions about print widths of types like
14288 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
14289 intptr_t when converting between pointer and integer, to avoid GCC
14290 warnings about wrong width.
14292 2012-05-09 Eli Zaretskii <eliz@gnu.org>
14294 * w32proc.c (new_child): Force Windows to reserve only 64KB of
14295 stack for each reader_thread, instead of defaulting to 8MB
14296 determined by the linker. This avoids failures in creating
14297 subprocesses on Windows 7, see the discussion in this thread:
14298 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
14300 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
14302 Fix up display of the *Minibuf-0* buffer in the mini window.
14303 * keyboard.c (read_char): Don't clear the echo area if there's no
14305 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
14306 contents of *Minibuf-0*) if there's no message displayed in its stead.
14308 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
14310 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
14313 2012-05-06 Chong Yidong <cyd@gnu.org>
14315 * lisp.mk (lisp): Update.
14317 2012-05-05 Jim Meyering <meyering@redhat.com>
14319 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
14321 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
14323 * data.c (PUT_ERROR): New macro.
14324 (syms_of_data): Use it. Add new error type `user-error'.
14325 * undo.c (user_error): New function.
14326 (Fprimitive_undo): Use it.
14327 * print.c (print_error_message): Adjust print style for `user-error'.
14328 * keyboard.c (user_error): New function.
14329 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
14331 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
14333 Do not limit current-time-string to years 1000..9999.
14334 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
14335 (Fcurrent_time_string): Support any year that is supported by the
14336 underlying localtime representation. Don't use asctime, as it
14337 has undefined behavior for years outside the range -999..9999.
14339 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
14341 Fix race conditions involving setenv, gmtime, localtime, asctime.
14342 Without this fix, interrupts could mess up code that uses these
14343 nonreentrant functions, since setting TZ invalidates existing
14344 tm_zone or tzname values, and since most of these functions return
14345 pointers to static storage.
14346 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
14347 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
14348 Grow the critical sections to include not just invoking
14349 localtime/gmtime, but also accessing these functions' results
14350 including their tm_zone values if any, and any related TZ setting.
14351 (format_time_string): Last arg is now struct tm *, not struct tm **,
14352 so that the struct tm is saved in the critical section.
14353 All callers changed. Simplify allocation of initial buffer, partly
14354 motivated by the fact that memory allocation needs to be outside
14355 the critical section.
14357 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
14359 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
14360 with RESET_INTERVAL.
14362 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
14363 Remove duplicated buffer name initialization.
14365 2012-05-02 Jim Meyering <jim@meyering.net>
14367 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
14369 * xfns.c (x_window): Use xstrdup (Bug#11375).
14371 2012-05-02 Eli Zaretskii <eliz@gnu.org>
14373 * xdisp.c (pos_visible_p): If already at a newline from the
14374 display string before the 'while' loop, don't walk back the glyphs
14375 from it3.glyph_row. Solves assertion violation when the display
14376 string begins with a newline (egg.el). (Bug#11367)
14378 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
14380 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
14383 2012-05-01 Glenn Morris <rgm@gnu.org>
14385 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
14386 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
14387 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
14388 All were removed before 23.1.
14390 * dispnew.c: Remove HAVE_LIBNCURSES test;
14391 it is always true on relevant platforms.
14393 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
14394 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
14396 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
14398 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
14400 * .gdbinit (xpr): Remove checks for no longer existing misc types.
14401 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
14404 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
14406 Do not avoid creating empty evaporating overlays (Bug#9642).
14407 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
14408 That is, do not delete an evaporating overlay if it becomes
14409 empty after its bounds are adjusted to fit within its buffer.
14410 This fix caused other problems, and I'm reverting it until we get
14411 to the bottom of them.
14413 2012-04-27 Chong Yidong <cyd@gnu.org>
14415 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
14417 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14419 * xdisp.c (pos_visible_p): If the window start position is beyond
14420 ZV, start the display from buffer beginning. Prevents assertion
14421 violation in init_iterator when the minibuffer window is scrolled
14422 via the scroll bar.
14424 * window.c (window_scroll_pixel_based): Likewise.
14426 2012-04-27 Chong Yidong <cyd@gnu.org>
14428 * keymap.c (where_is_internal): Doc fix (Bug#10872).
14430 2012-04-27 Glenn Morris <rgm@gnu.org>
14432 * fileio.c (Fcopy_file, Fset_file_selinux_context):
14433 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
14435 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14437 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
14438 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
14440 2012-04-26 Eli Zaretskii <eliz@gnu.org>
14442 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
14443 display element, check also the underlying string or buffer
14444 character. (Bug#11341)
14446 * w32menu.c: Include w32heap.h.
14447 (add_menu_item): If the call to AppendMenuW (via
14448 unicode_append_menu) fails, disable Unicode menus only if we are
14449 running on Windows 9X/Me.
14451 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
14453 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
14454 (xgetint): Add missing shift for LSB tags.
14456 2012-04-24 Martin Rudalics <rudalics@gmx.at>
14458 * keyboard.c (read_char): Don't wipe echo area for select window
14459 events: These might get delayed via `mouse-autoselect-window'
14462 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
14464 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
14465 manipulation of :loaded-from data.
14467 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
14469 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
14470 now a cons (bug#11311).
14472 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
14474 Do not create empty overlays with the evaporate property (Bug#9642).
14475 * buffer.c (Fmove_overlay): Delete an evaporating overlay
14476 if it becomes empty after its bounds are adjusted to fit within
14477 its buffer. Without this fix, in a nonempty buffer (let ((o
14478 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
14479 yields an empty overlay that has the evaporate property, which is
14480 not supposed to happen.
14482 Fix minor GTK3 problems found by static checking.
14483 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14484 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14485 (struct _EmacsFixedClass, emacs_fixed_get_type):
14486 Move decls here from emacsgtkfixed.h, since they needn't be public.
14487 (emacs_fixed_get_type): Now static.
14488 (emacs_fixed_class_init): Omit unused local.
14489 (emacs_fixed_child_type): Remove; unused.
14490 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14491 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14492 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
14493 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
14494 (EMACS_FIXED_GET_CLASS): Remove; unused.
14495 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
14497 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
14498 Problem reported by Juanma Barranquero for Windows -Wunused-function.
14500 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14502 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
14503 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
14504 (__malloc_size_t, __malloc_ptrdiff_t):
14505 Remove. All uses removed, replaced by the definiens if needed,
14506 since we can assume C89 or better now.
14507 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

14515 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
14516 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
14517 Define using prototypes, not old style.
14518 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
14519 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
14520 (align): Don't assume that signed integer overflow wraps around.
14521 Omit unused local var.
14522 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
14523 (_free_internal_nolock, memalign, mallochook, reallochook):
14524 Omit no-longer-needed casts.
14525 (valloc): Use getpagesize, not __getpagesize.
14526 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
14527 (struct hdr): The 'magic' member is now size_t, not unsigned long.
14529 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
14531 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
14533 Move functions from C to Lisp. Make non-blocking method calls
14534 the default. Implement further D-Bus standard interfaces.
14536 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
14537 (QCdbus_request_name_allow_replacement)

14549 (XD_DBUS_VALIDATE_BUS_NAME, XD_DBUS_VALIDATE_PATH)
14550 (XD_DBUS_VALIDATE_INTERFACE, XD_DBUS_VALIDATE_MEMBER): New macros.
14551 (XD_CHECK_DBUS_SERIAL): Rename from CHECK_DBUS_SERIAL_GET_SERIAL.
14552 (xd_signature, xd_append_arg): Allow float for integer types.
14553 (xd_get_connection_references): New function.
14554 (xd_get_connection_address): Rename from xd_initialize.
14555 Return cached address.
14556 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
14557 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp
14559 (Fdbus_init_bus): New optional arg PRIVATE. Cache address.
14560 Return number of refcounts.

14593 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
14595 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14597 * sysdep.c [__FreeBSD__]: Minor cleanups.
14598 (list_system_processes, system_process_attributes) [__FreeBSD__]:
14599 Use Emacs indenting style more consistently. Avoid some casts.

14604 * sysdep.c (list_system_processes, system_process_attributes):
14605 Add implementation for FreeBSD (Bug#5243).

14611 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
14613 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
14614 It is never used otherwise.
14616 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
14618 * print.c (print_preprocess): Only check print_depth if print-circle
14620 (print_object): Check for cycles even when print-circle is nil and
14621 print-gensym is t, but only check print_depth if print-circle is nil.
14623 2012-04-20 Chong Yidong <cyd@gnu.org>
14625 * process.c (wait_reading_process_output): If EIO occurs on a pty,
14626 set the status to "failed" and ensure that sentinel is run.
14628 2012-04-20 Glenn Morris <rgm@gnu.org>
14630 * process.c (Fset_process_inherit_coding_system_flag)
14631 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

14641 farther than the first row after the header line, if any.
14642 Don't consider the header-line row as "partially visible", even if
14643 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
14645 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

14659 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
14660 -Wunused-result, -Wunused-variable. This should go away once
14661 the Emacs and Gnulib regex code is merged.
14662 (xmalloc, xrealloc): Now static.
14664 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

14681 New extern decls, to avoid calling undeclared functions.
14682 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
14683 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
14684 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14685 (NEED_MEM_INSERT): New macro.
14686 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14687 Remove one incorrect comment and fix another.

14701 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
14702 Remove decls. This fixes an "It stinks!".
14704 * alloc.c (which_symbols): Fix alignment issue / type clash.
14706 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
14708 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
14709 (struct Lisp_Misc_Any): Likewise.

14723 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14724 * s/netbsd.h, s/sol2-6.h:
14725 Remove definition of GC_MARK_STACK, since the default now works.
14726 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
14727 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
14728 no longer the default.
14729 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14731 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
14733 * lread.c (lisp_file_lexically_bound_p):
14734 Fix hang at ";-*-\n" (bug#11238).
14736 2012-04-14 Eli Zaretskii <eliz@gnu.org>
14738 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
14739 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

14752 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
14754 2012-04-11 Daniel Colascione <dancol@dancol.org>
14756 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14757 against is gone. It's better to use vfork now so that when Cygwin
14758 gains a new, working vfork, we use it automatically (bug#10398).
14760 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
14762 * window.c (save_window_save): Obey window-point-insertion-type.

14780 * w32.c (w32_delayed_load): Record the full path of the library
14781 being loaded (bug#10424).
14783 2012-04-09 Glenn Morris <rgm@gnu.org>
14785 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14786 not just in the obarray, before snarfing them. (Bug#11036)

14803 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14804 attempts per process (connection).
14806 2012-04-09 Chong Yidong <cyd@gnu.org>
14808 * eval.c (Fuser_variable_p, user_variable_p_eh)

14810 (Fdefvar): Caller changed.
14812 * callint.c (Finteractive, Fcall_interactively):
14813 * minibuf.c (Fread_variable): Callers changed.
14815 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14817 * xdisp.c (set_cursor_from_row): If the display string appears in
14818 the buffer at position that is closer to point than the position
14819 after the display string, display the cursor on the first glyph of
14820 the display string. Fixes cursor display when a 'display' text
14821 property immediately follows invisible text. (Bug#11094)
14823 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14825 composite.c: use 'double' consistently
14826 * composite.c (get_composition_id): Use 'double' consistently
14827 instead of converting 'float' to 'double' and vice versa; this is
14828 easier to understand and avoids a GCC warning.
14830 2012-04-09 Glenn Morris <rgm@gnu.org>
14832 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14833 preparation for dumping it with emacs. (Bug#4789)

14855 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14856 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14857 objects, as mark_maybe_pointer will catch them otherwise.

14875 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14876 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14877 [!WINDOWSNT]: New macros.
14878 (init_libxml2_functions, libxml2_loaded_p): New functions.
14879 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14880 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14881 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14882 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14884 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14885 Call init_libxml2_functions before calling libxml2 functions.
14886 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14888 * emacs.c: Don't include libxml/parser.h.
14889 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14890 xmlCleanupParser directly.
14892 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14894 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14896 * indent.c (Fvertical_motion): If there is a display string at
14897 point, use it.vpos to compute how many lines to backtrack after
14898 move_it_to point. (Bug#11133)
14900 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14902 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14903 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14904 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14905 macros related to unification of CJK characters. For the details,
14906 see the discussion following the message here:
14907 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14909 2012-04-04 Chong Yidong <cyd@gnu.org>
14911 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14913 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14915 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

14923 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14925 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14926 position we get to after a call to move_it_to fails the
14927 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14928 only if we wind up in a string from display property. (Bug#11063)
14930 * window.c (Fdelete_other_windows_internal): Invalidate the row
14931 and column information about mouse highlight, so that redisplay
14932 restores it after reallocating the glyph matrices. (Bug#7464)
14934 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14935 string comes from a `display' text property, use the buffer
14936 position of that property as if we actually saw that position in
14938 (move_it_by_lines): Remove the assertion that
14939 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14940 violated when there's a before-string at the beginning of a line.
14943 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14945 * xdisp.c (append_space_for_newline): If the default face was

14947 (extend_face_to_end_of_line): Use the remapped default face for
14948 extending the face to the end of the line.
14949 (display_line): Call extend_face_to_end_of_line when the default
14950 face was remapped. (Bug#11068)
14952 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14954 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
14956 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

14972 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14973 (command_loop_1): Use it; inhibit selection update for

14978 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14980 2012-03-25 Kenichi Handa <handa@m17n.org>
14982 * dispextern.h (struct glyph): Change the bit length of
14983 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14985 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14987 * s/ms-w32.h (tzname): Include time.h before redirecting to

14996 !SYNC_INPUT. (Bug#11080)
14998 2012-03-23 Eli Zaretskii <eliz@gnu.org>
15000 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
15001 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
15002 when fetching a multibyte character consumes more bytes than
15003 CHAR_BYTES returns, due to unification of CJK characters in
15004 string_char. (Bug#11073)
15006 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
15008 * process.c (wait_reading_process_output): Handle pty disconnect
15009 by refraining from sending oneself a SIGCHLD (bug#10933).
15011 2012-03-22 Chong Yidong <cyd@gnu.org>
15013 * dispextern.h (struct it): New member string_from_prefix_prop_p.

15038 it fit in a valid range (Bug#11003).
15040 2012-03-18 Eli Zaretskii <eliz@gnu.org>
15042 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
15043 that is not from display property, accept the row as a "cursor
15044 row" if one of the string's character has a non-nil `cursor'
15045 property. Fixes cursor positioning when there are newlines in
15046 overlay strings, e.g. in icomplete.el. (Bug#11035)
15048 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
15050 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

15079 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
15082 2012-03-03 Glenn Morris <rgm@gnu.org>
15084 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
15086 2012-03-02 Eli Zaretskii <eliz@gnu.org>

15099 2012-02-29 Eli Zaretskii <eliz@gnu.org>
15101 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
15102 push_it before setting up the iterator for the first overlay
15103 string, even if we have an empty string loaded.
15104 (next_overlay_string): If there's an empty string on the iterator
15105 stack, pop the stack. (Bug#10903)
15107 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
15109 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
15110 Suggested by Stefan Monnier in
15111 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
15112 * alloc.c (widen_to_Lisp_Object): New static function.
15113 (mark_memory): Also mark Lisp_Objects by fetching pointer words
15114 and widening them to Lisp_Objects. This would work even if
15115 USE_LSB_TAG is defined and wide integers are used, which might
15116 happen in a future version of Emacs.
15118 2012-02-25 Chong Yidong <cyd@gnu.org>
15120 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

15125 before saving to clipboard manager.
15127 2012-02-24 Chong Yidong <cyd@gnu.org>
15129 * keyboard.c (process_special_events): Handle all X selection
15130 requests in kbd_buffer, not just the next one (Bug#8869).
15132 2012-02-23 Chong Yidong <cyd@gnu.org>
15134 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
15135 call when setting menu-bar-lines and tool-bar-lines parameters.
15136 (unwind_create_frame_1): New helper function.
15138 * window.c (inhibit_window_configuration_change_hook): New var.

15157 when computing $valmask.
15159 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
15160 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
15161 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
15162 It's useless in that case, and it can cause problems on hosts
15163 that allocate halves of EMACS_INT values separately.
15164 Reported by Dan Horák. Diagnosed by Andreas Schwab in
15165 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
15166 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
15167 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
15168 it avoids undefined behavior on hosts where shifting right by more
15169 than the word width has undefined behavior.
15171 2012-02-19 Chong Yidong <cyd@gnu.org>
15173 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
15174 (Funhandled_file_name_directory, Ffile_name_as_directory)
15175 (Fdirectory_file_name, Fexpand_file_name)
15176 (Fsubstitute_in_file_name): Protect against invalid file handler
15177 return values (Bug#10845).

15191 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
15193 2012-02-15 Chong Yidong <cyd@gnu.org>
15195 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
15196 marked as special. Also, starting docstrings with * is obsolete.

15211 2012-02-12 Chong Yidong <cyd@gnu.org>
15213 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
15214 as that creates a dangerous corner case.
15216 * window.c (Fdelete_window_internal): Invalidate the mouse
15217 highlight (Bug#9904).
15219 2012-02-12 Glenn Morris <rgm@gnu.org>

15224 * nsselect.m (Fx_own_selection_internal)
15225 (Fx_disown_selection_internal, Fx_selection_exists_p)
15226 (Fx_selection_owner_p, Fx_get_selection_internal):
15227 Sync docs and argument specs with the xselect.c versions.
15229 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

15249 2012-02-07 Chong Yidong <cyd@gnu.org>
15251 * buffer.c (Fbuffer_local_variables)
15252 (buffer_lisp_local_variables): Handle unbound vars correctly;
15253 don't let Qunbound leak into Lisp.
15255 2012-02-07 Glenn Morris <rgm@gnu.org>
15257 * image.c (Fimagemagick_types): Doc fix.
15259 * image.c (imagemagick-render-type): Change it from a lisp object
15260 to an integer. Move the doc here from the lisp manual.

15277 2012-02-04 Eli Zaretskii <eliz@gnu.org>
15279 * w32.c (get_emacs_configuration_options):
15280 Include --enable-checking, if specified, in the return value.

15290 before BEGV. (Bug#10696)
15292 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
15294 Handle overflow when computing char display width (Bug#9496).
15295 * character.c (char_width): Return EMACS_INT, not int.
15296 (char_width, c_string_width): Check for overflow when
15297 computing the width; this is possible now that individual
15298 characters can have unbounded width. Problem introduced
15299 by merge from Emacs 23 on 2012-01-19.

15323 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
15325 (x_produce_glyphs): If the component of a composition is a null
15326 string, set it->pixel_width to 1 to avoid zero-width glyph.

15330 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
15331 first 2 arguments are identical. This makes inserting large
15332 output from a subprocess an order of magnitude faster on
15333 MS-Windows, where all sbrk'ed memory is always contiguous.
15335 2012-01-31 Glenn Morris <rgm@gnu.org>

15428 Update template values to be closer to their typical values these days.
15430 2012-01-09 Eli Zaretskii <eliz@gnu.org>
15432 * xdisp.c (rows_from_pos_range): Accept additional argument
15433 DISP_STRING, and accept any glyph in a row whose object is that
15434 string as eligible for mouse highlight. Fixes mouse highlight of
15435 display strings from overlays. (Bug#10464)
15437 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
15439 emacs: fix an auto-save permissions race condition (Bug#10400)
15440 * fileio.c (auto_saving_dir_umask): New static var.
15441 (Fmake_directory_internal): Use it.
15442 (do_auto_save_make_dir): Set it, instead of invoking chmod after

15446 (Fdo_auto_save): Catch all errors, not just file errors, so
15447 that the var is always cleared.

15504 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
15505 property that ends at ZV, so that the bidi iteration could be

15786 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
15787 verifies glyph row's hash code--we have just reallocated the

15949 Otherwise, valgrind does not work on some platforms.
15950 Problem reported by Andreas Schwab in
15951 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
15952 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15953 is set, removing the need for VIRT_ADDRESS_VARIES.
15954 (PURE_P): Use a more-efficient implementation that needs just one

15956 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
15957 to 4 (xorl, subq, cmpq, setbe).
15958 * alloc.c (pure): Always extern now, since that's the
15959 VIRT_ADDR_VARIES behavior.
15960 (PURE_POINTER_P): Use a single comparison, not two, for
15961 consistency with the new puresize.h.
15962 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

16429 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
16430 <oslsachem@gmail.com> for helping to debug this.
16432 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
16433 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
16434 (g_b_init_get_glyph_outline_w): New static variables.
16435 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
16436 (GetGlyphOutlineW_Proc): New typedefs.
16437 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
16438 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
16440 (w32font_open_internal, compute_metrics):
16441 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
16442 instead of calling the "wide" APIs directly.
16444 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
16446 * w32.h (syms_of_w32font): Add prototype.
16448 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
16450 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
16451 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
16452 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
16453 (Fmove_to_window_line): Doc fix.
16455 2011-10-27 Chong Yidong <cyd@gnu.org>
16457 * process.c (make_process): Set gnutls_state to NULL.
16459 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
16460 non-NULL, regardless of GNUTLS_INITSTAGE.
16461 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
16462 an error. Set process slots as soon as we allocate them.
16464 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
16466 2011-10-27 Chong Yidong <cyd@gnu.org>
16468 * gnutls.c (emacs_gnutls_deinit): New function.
16469 Deallocate credentials structures as well as calling gnutls_deinit.
16470 (Fgnutls_deinit, Fgnutls_boot): Use it.
16472 * process.c (make_process): Initialize GnuTLS credentials to NULL.
16473 (deactivate_process): Call emacs_gnutls_deinit.
16475 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
16477 * image.c (x_create_x_image_and_pixmap):
16478 * w32.c (sys_rename, w32_delayed_load):
16479 * w32font.c (fill_in_logfont):
16480 * w32reg.c (x_get_string_resource): Silence compiler warnings.
16482 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
16484 * w32fns.c (w32_default_color_map): New function,
16485 extracted from Fw32_default_color_map.
16486 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
16488 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
16490 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
16492 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
16494 * keyboard.c (test_undefined): New function (bug#9751).
16495 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
16497 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
16499 * sysdep.c (init_sys_modes): Fix the check for the controlling
16500 terminal (Bug#6649).
16502 2011-10-20 Eli Zaretskii <eliz@gnu.org>
16504 * dispextern.h (struct bidi_it): New member next_en_type.
16506 * bidi.c (bidi_line_init): Initialize the next_en_type member.
16507 (bidi_resolve_explicit_1): When next_en_pos is valid for the
16508 current character, check also for next_en_type being WEAK_EN.
16509 (bidi_resolve_weak): Don't enter the expensive loop if the current
16510 position is before next_en_pos. Record the bidi type of the first
16511 non-ET, non-BN character we find, in addition to its position.
16512 (bidi_level_of_next_char): Invalidate next_en_type when
16513 next_en_pos is over-stepped.
16515 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
16517 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
16518 * editfns.c: Rewrite current-time-zone so that it invokes
16519 the equivalent of (format-time-string "%Z") to get the time zone name.
16520 This fixes a bug when the time zone name contains characters that
16521 need converting from the system time locale to Emacs internal format.
16522 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
16523 that patch fixed format-time-string to do the conversion, but
16524 I forgot to fix current-time-zone.
16525 (format_time_string): New function, containing most of
16526 what Fformat_time_string used to contain.
16527 (Fformat_time_string): Rewrite in terms of format_time_string.
16528 This doesn't change this function's behavior.
16529 (current-time-zone): Rewrite to use format_time_string.
16530 This fixes the bug reported by Michael Schierl in
16531 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
16532 Jason Rumney's 2007-06-07 change worked around this bug, but
16534 * systime.h (tzname, timezone): Remove no-longer-used declarations.
16536 2011-10-19 Eli Zaretskii <eliz@gnu.org>
16538 * xdisp.c (start_display): If the character at POS is displayed
16539 via a display vector, reset IT->current.dpvec_index to zero.
16540 (try_window_reusing_current_matrix): If a line ends in a display
16541 vector or the next line starts in a display vector, continue
16542 redrawing the window even though the character position of
16543 start_row was reached.
16546 2011-10-18 Chong Yidong <cyd@gnu.org>
16548 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
16549 with nobreak-char-display too.
16551 2011-10-18 Eli Zaretskii <eliz@gnu.org>
16553 Fix part 3 of bug#9771.
16554 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
16555 (bidi_resolve_neutral): Don't enter the expensive loop looking for
16556 non-neutral characters if the current character is a paragraph
16557 separator (a.k.a. Newline). This avoids running the same
16558 expensive loop twice, once when we consume the preceding newline
16559 and the other time when the line actually needs to be displayed.
16560 Avoid the loop when we see neutrals on the base embedding level
16561 following a character whose directionality is the same as the
16562 paragraph's. This avoids running the expensive loop when a line
16563 ends in a long sequence of neutrals, like control characters.
16564 Add assertion against STRONG_AL type. Slightly rearrange code
16565 that determines the type of a neutral given the first non-neutral
16567 (bidi_level_of_next_char): Set next_en_pos to zero when
16568 invalidating its info.
16570 2011-10-17 Eli Zaretskii <eliz@gnu.org>
16572 * xdisp.c (push_display_prop): Determine whether to record string
16573 or buffer position by IT->string, not by IT->method. Allow
16574 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
16575 (move_it_vertically_backward): Don't look for character position
16576 immediately after the newline when in a continuation line.
16579 2011-10-15 Martin Rudalics <rudalics@gmx.at>
16581 * window.c (coordinates_in_window): Rewrite and delabelize
16582 vertical border check. (Bug#5357) (Bug#9618)
16584 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
16586 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
16587 errors in XSetWindowBorder (bug#9310).
16589 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
16591 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
16592 avoid crash when xmalloc overrun checking is enabled.
16594 2011-10-13 Eli Zaretskii <eliz@gnu.org>
16596 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
16597 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
16598 cursor motion with <left> and <right> arrow keys.
16600 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
16601 some callers set that themselves.
16603 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16605 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
16606 display string and the previous row comes from the same string and
16607 is empty. (Bug#9739) (Bug#9738)
16609 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
16611 * doc.c (get_doc_string): Encode file name (bug#9735).
16613 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16615 * bidi.c (bidi_level_of_next_char):
16616 * xdisp.c (get_visually_first_element): Remove old incorrect
16617 comments regarding the Unicode Line Separator character.
16619 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
16621 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
16623 * alloc.c (Fgc_status): Do not access beyond zombies array
16624 boundary if nzombies > MAX_ZOMBIES.
16625 * alloc.c (dump_zombies): Add missing format specifier.
16627 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16629 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16630 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16632 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16633 Some packages use them to denote characters with modifiers.
16635 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16637 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16638 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16639 matching a pp-number. Rename parameter var to var1.
16641 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16643 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16645 2011-10-08 Glenn Morris <rgm@gnu.org>
16647 * callint.c (Fcall_interactively): Give a more explicit error for the
16648 'c' case with a non-character input. (Bug#8479)
16650 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16652 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16654 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16655 lines that are hscrolled on the left.
16657 * dispnew.c (buffer_posn_from_coords): Account for a possible
16658 presence of header-line. (Bug#4426)
16660 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16662 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16663 Don't advertise functionality which we discourage or doesn't work.
16665 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16667 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16668 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16669 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16670 this makes Emacs dump core during garbage collection on rare
16671 occasions. sizeof is obviously inferior to offsetof here, so
16672 stick with offsetof.
16673 (GC_POINTER_ALIGNMENT): New macro.
16674 (mark_memory): Omit 3rd (offset) arg; caller changed.
16675 Don't assume EMACS_INT alignment is the same as pointer alignment.
16677 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16679 * keyboard.c (read_key_sequence_remapped): New var.
16680 (read_key_sequence): Compute remapping in the right buffer.
16681 (command_loop_1): Use read_key_sequence's remapping directly.
16683 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16685 * dired.c (file_name_completion): Don't expand file name.
16686 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16687 before checking file name handler.
16689 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16690 they've been requested explicitly (bug#9591).
16692 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16694 * keymap.c (Fsingle_key_description): Use make_specified_string
16695 instead of build_string to build string from push_key_description.
16698 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16700 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16701 This fixes a Y2038 bug on 64-bit hosts.
16702 * buffer.c (reset_buffer):
16703 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16704 (Fclear_buffer_auto_save_failure):
16705 Use 0, not -1, to represent an unset failure time, since time_t
16706 might not be signed.
16708 Remove dependency on glibc malloc internals.
16709 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16710 Move back here from lisp.h, but with their new implementations.
16711 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16712 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16713 * charset.c (charset_table_init): New static var.
16714 (syms_of_charset): Use it instead of xmalloc. This removes a
16715 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16716 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16717 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16718 Move back to alloc.c.
16719 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16720 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16722 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16724 * nsterm.m (windowDidResize): Call x_set_window_size only when
16725 ns_in_resize is true. Otherwise set pixelwidth/height and
16726 call change_frame_size (Bug#9628).
16728 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16730 Port --enable-checking=all to Fedora 14 x86-64.
16731 * charset.c (syms_of_charset): Also account for glibc malloc's
16732 internal overhead when calculating the initial malloc maximum.
16734 Port --enable-checking=all to Fedora 14 x86.
16735 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16737 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16738 (overrun_check_realloc, overrun_check_free):
16739 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16740 That way, xmalloc returns a properly-aligned pointer even if
16741 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16742 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16743 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16744 into account when calculating the initial malloc maximum.
16745 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16746 Move here from alloc.c, so that charset.c can use it too.
16747 Properly align; the old code wasn't right for common 32-bit hosts
16748 when configured with --enable-checking=all.
16749 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16750 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16752 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16754 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16757 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16759 * xdisp.c (compute_display_string_end): If there's no display
16760 string at CHARPOS, return -1.
16762 * bidi.c (bidi_fetch_char): When compute_display_string_end
16763 returns a negative value, treat the character as a normal
16764 character not covered by a display string. (Bug#9624)
16766 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16768 * lread.c (Fread_from_string): Fix typo in docstring.
16770 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16772 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16773 newline, reseat the iterator instead of bidi-iterating there one
16774 character at a time. (Bug#9610)
16775 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16776 TO_CHARPOS if the bidi iterator is at base embedding level.
16778 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16780 * lread.c (readevalloop): Use correct code for NBSP.
16781 (read1): Likewise. (Bug#9608)
16783 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16785 * dbusbind.c (Fdbus_register_signal): When service is not
16786 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16788 2011-09-25 Glenn Morris <rgm@gnu.org>
16790 * buffer.c (truncate-lines): Doc fix.
16792 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16794 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16795 (Fset_window_next_buffers): Doc fix.
16797 2011-09-24 Glenn Morris <rgm@gnu.org>
16799 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16801 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16803 Fix minor problems found by static checking.
16804 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16805 * indent.c (Fvertical_motion): Fix == vs = typo.
16807 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16809 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16810 Default value is now t. Doc fix.
16812 * indent.c (Fvertical_motion): Compute and apply the overshoot
16813 logic when moving up, not only when moving down. Fix the
16814 confusing name and values of the it_overshoot_expected variable;
16815 logic changes accordingly. (Bug#9254) (Bug#9549)
16817 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16818 CHARPOS is covered by a display string which includes newlines.
16819 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16820 is covered by a display string with embedded newlines.
16822 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16824 * dbusbind.c (Fdbus_register_signal): Add match rule to
16825 Vdbus_registered_objects_table. (Bug#9581)
16826 (Fdbus_register_method, Vdbus_registered_objects_table):
16829 2011-09-24 Jim Meyering <meyering@redhat.com>
16831 do not ignore write error for any output size
16832 The previous change was incomplete.
16833 While it makes emacs --batch detect the vast majority of stdout
16834 write failures, errors were still ignored whenever the output size is
16835 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16836 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16837 && echo FAIL: ignored write error
16838 FAIL: ignored write error
16839 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16840 && echo FAIL: ignored write error
16841 FAIL: ignored write error
16842 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16844 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16846 * emacs.c (Fkill_emacs): In noninteractive mode exit
16847 non-successfully if a write error occurred on stdout. (Bug#9574)
16849 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16851 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16854 * dispextern.h (struct it): Update the comment documenting what
16857 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16859 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16860 a display string, extend search for cursor position to end of row.
16861 (find_row_edges): If the row ends in a newline from a display
16862 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16863 Handle the case of a display string with multiple newlines.
16864 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16865 non-empty line. Fixes confusing cursor motion with arrow keys at
16866 the beginning of a line that starts with whitespace.
16868 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>

16873 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16875 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16876 boolean (Bug#9154).
16878 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16880 * xdisp.c (display_line): Record maximum and minimum buffer
16881 positions even if no glyphs were produced (e.g., by a zero-width
16882 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16883 buffer positions that will be removed from the glyph row because
16885 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16886 column is beyond frame width: don't subtract 1 "pixel" when
16887 computing width of the stretch.
16888 (reseat_at_next_visible_line_start): Undo the change made on
16889 2011-09-17 that saved paragraph information and restored it after
16890 the call to `reseat'. (Bug#9545)
16892 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16894 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16895 and turn window cursor on if cleared (Bug#9415).
16897 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16899 * search.c (boyer_moore): Take unibyte characters from pattern
16900 literally. (Bug#9458)

16906 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16908 Fix minor problem found by static checking.
16909 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16910 initialized, to pacify gcc -Wuninitialized.
16912 * fileio.c: Report proper errno when syscall falls.
16913 (Finsert_file_contents): Save and restore errno,
16914 so that report_file_error outputs the correct diagnostic.
16915 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16917 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16919 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16921 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16923 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16924 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16926 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16928 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16929 about the current paragraph and restore it after the call to reseat.
16931 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16932 (bidi_find_paragraph_start): Search back for paragraph beginning
16933 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16934 (bidi_move_to_visually_next): Only trigger paragraph-related
16935 computations when the last character is a newline or at EOB, not
16936 just any NEUTRAL_B. (Bug#9470)
16938 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16939 truncated lines if point is covered by a display string. (Bug#9524)
16941 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16943 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16944 (cons_to_x_long): New function.
16945 (lisp_data_to_selection_data): Use it. Correct the test for
16946 short-versus-long data; it was negated. Break out of vector
16947 loop, for efficiency, when a long datum is discovered.
16949 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16951 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16953 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16955 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16956 GCC PR/17406) by declaring this function with external scope.
16958 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16960 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16961 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16963 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16965 * editfns.c (Fformat): Correctly handle text properties on "%%".

16971 * term.c (encode_terminal_code):
16972 * composite.c (composition_update_it, get_composition_id):
16973 * xdisp.c (get_next_display_element)
16974 (fill_composite_glyph_string): Add comments about special meaning
16975 of TAB characters in a composition.
16977 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16979 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16980 This occurs when processing a multibyte format.
16981 Problem reported by Wolfgang Jenker.
16983 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16985 * xdisp.c (try_cursor_movement): Only check for exact match if
16986 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16988 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16990 Remove unused external symbols.
16991 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16992 * xdisp.c (calc_pixel_width_or_height): Now static.
16993 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16994 * indent.c (check_display_width):
16995 * w32term.c: Fix comment to match code.
16996 * xterm.c, xterm.h (x_catching_errors): Remove.
16998 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
17000 * xselect.c: Use signed conversions more consistently (Bug#9498).
17001 (selection_data_to_lisp_data): Assume incoming selection data are
17002 signed integers, not unsigned. This is to be consistent with
17003 outgoing selection data, which was modified to use signed integers
17004 in as part of the fix to Bug#9196 in response to Jan D.'s comment
17005 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
17006 expects long, not unsigned long.
17008 2011-09-14 Eli Zaretskii <eliz@gnu.org>
17010 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
17011 computation of loop end. Reported by Johan Bockgård
17014 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
17016 * frame.c (Fother_visible_frames_p): Function deleted.
17018 2011-09-12 Eli Zaretskii <eliz@gnu.org>
17020 * indent.c (compute_motion): Process display vector front to back
17021 rather than the other way around. (Bug#2496)
17023 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
17025 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
17027 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
17029 * minibuf.c (Fread_from_minibuffer): Doc fix.
17031 2011-09-11 Eli Zaretskii <eliz@gnu.org>
17033 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
17034 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
17036 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
17038 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
17039 value for non-existent files.
17041 2011-09-11 Eli Zaretskii <eliz@gnu.org>
17043 * fileio.c (Finsert_file_contents): If the file cannot be opened,
17044 set its "size" to -1. This will set the modtime_size field of
17045 the corresponding buffer to -1, which is what
17046 verify-visited-file-modtime expects for files that do not exist.
17049 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
17051 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
17053 * lisp.h: ... from here. push_key_description is no longer
17054 defined in keyboard.c, so its declaration should not be in
17055 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
17056 logically belongs with push_key_description.
17058 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
17060 * buffer.h: Include <sys/types.h> instead of <time.h>.
17061 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
17062 Problem reported by Herbert J. Skuhra.
17064 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
17066 * xml.c (parse_region): Make the parsing work for
17067 non-comment-starting XML files again (bug#9144).
17069 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
17071 * image.c (gif_load): Fix calculation of bottom and right corner.
17074 2011-09-10 Eli Zaretskii <eliz@gnu.org>
17076 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
17077 redisplay in small windows.
17079 2011-09-09 Eli Zaretskii <eliz@gnu.org>
17081 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
17083 2011-09-08 Martin Rudalics <rudalics@gmx.at>
17085 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
17086 Operate on live windows only.
17088 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
17090 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
17092 2011-09-07 Eli Zaretskii <eliz@gnu.org>
17094 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
17095 only under bidi iteration.
17097 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
17099 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
17101 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17103 isnan: Fix porting problem to Solaris 10 with bundled gcc.
17104 Without this fix, the command to link temacs failed due to an
17105 undefined symbol __builtin_isnan. This is because
17106 /usr/include/iso/math_c99.h #defines isnan(x) to
17107 __builtin_isnan(x), but the bundled gcc, which identifies itself
17108 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
17110 * floatfns.c (isnan): #undef, and then #define to a clone of
17112 (Fisnan): Always define, since it's always available now.
17113 (syms_of_floatfns): Always define isnan at the Lisp level.
17115 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17117 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
17119 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17121 * fileio.c: Fix bugs with large file offsets (Bug#9428).
17122 The previous code assumed that file offsets (off_t values) fit in
17123 EMACS_INT variables, which is not true on typical 32-bit hosts.
17124 The code messed up by falsely reporting buffer overflow in cases
17125 such as (insert-file-contents "big" nil 1 2) into an empty buffer
17126 when "big" contains more than 2**29 bytes, even though this
17127 inserts just one byte and does not overflow the buffer.
17128 (Finsert_file_contents): Store file offsets as off_t
17129 values, not as EMACS_INT values. Check for overflow when
17130 converting between EMACS_INT and off_t. When checking for
17131 buffer overflow or for overlap, take the offsets into account.
17132 Don't use EMACS_INT for small values where int suffices.
17133 When checking for overlap, fix a typo: ZV was used where
17134 ZV_BYTE was intended.
17135 (Fwrite_region): Don't assume off_t fits into 'long'.
17136 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
17138 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
17140 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
17142 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17144 sprintf-related integer and memory overflow issues (Bug#9412).
17146 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
17147 (esprintf, exprintf, evxprintf): New functions.
17148 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
17149 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
17150 (modify_event_symbol): Do not assume that the length of
17151 name_alist_or_stem is safe to alloca and fits in int.
17152 (Fexecute_extended_command): Likewise for function name and binding.
17153 (Frecursion_depth): Wrap around reliably on integer overflow.
17154 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
17155 since some callers pass EMACS_INT values.
17156 (Fsingle_key_description): Don't crash if symbol name contains more
17157 than MAX_ALLOCA bytes.
17158 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
17159 (get_minibuffer): Arg is now EMACS_INT, not int.
17160 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
17161 (esprintf, exprintf, evxprintf): New decls.
17162 * window.h (command_loop_level, minibuf_level): Reflect API changes.
17164 * dbusbind.c (signature_cat): New function.
17165 (xd_signature, Fdbus_register_signal):
17166 Do not overrun buffer; instead, report string overflow.
17168 * dispnew.c (add_window_display_history): Don't overrun buffer.
17169 Truncate instead; this is OK since it's just a log.
17171 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
17172 even if the time zone offset is outlandishly large.
17173 Don't mishandle offset == INT_MIN.
17175 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
17176 when creating daemon; the previous buffer-overflow check was incorrect.
17178 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
17179 which has the guts of the old verror function.
17181 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
17182 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
17184 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
17185 (font_unparse_xlfd): Don't blindly alloca long strings.
17186 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
17187 fits in int, when using sprintf. Use single snprintf to count
17188 length of string rather than counting it via multiple sprintfs;
17189 that's simpler and more reliable.
17190 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
17191 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
17192 sprintf, in case result does not fit in int.
17194 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
17195 (fontset_from_font): Print it.
17197 * frame.c (tty_frame_count): Now printmax_t, not int.
17198 (make_terminal_frame, set_term_frame_name): Print it.
17199 (x_report_frame_params): In X, window IDs are unsigned long,
17200 not signed long, so print them as unsigned.
17201 (validate_x_resource_name): Check for implausibly long names,
17202 and don't assume name length fits in 'int'.
17203 (x_get_resource_string): Don't blindly alloca invocation name;
17204 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
17207 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
17208 (xg_check_special_colors, xg_set_geometry):
17209 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
17211 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
17212 Use esprintf, not sprintf, in case result does not fit in int.
17214 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17215 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
17216 it as a large positive number.
17217 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
17218 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17220 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
17221 in case result does not fit in int.
17223 * print.c (float_to_string): Detect width overflow more reliably.
17224 (print_object): Make sprintf buffer a bit bigger, to avoid potential
17225 buffer overrun. Don't assume list length fits in 'int'. Treat
17226 print length of 0 as 0, not as infinity; to be consistent with other
17227 uses of print length in this function. Don't overflow print length
17228 index. Don't assume hash table size fits in 'long', or that
17229 vectorlike size fits in 'unsigned long'.
17231 * process.c (make_process): Use printmax_t, not int, to format
17232 process-name gensyms.
17234 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
17236 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
17237 to avoid potential buffer overrun.
17239 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
17240 if X resource line is longer than 512 bytes.
17242 * xfns.c (x_window): Make sprintf buffer a bit bigger
17243 to avoid potential buffer overrun.
17245 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
17247 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
17249 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17251 Integer overflow fixes for scrolling, etc.
17252 Without these, Emacs silently mishandles large integers sometimes.
17253 For example, "C-u 4294967297 M-x recenter" was treated as if
17254 it were "C-u 1 M-x recenter" on a typical 64-bit host.
17256 * xdisp.c (try_window_id): Check Emacs fixnum range before
17257 converting to 'int'.
17259 * window.c (window_scroll_line_based, Frecenter):
17260 Check that an Emacs fixnum is in range before assigning it to 'int'.
17261 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
17262 values converted from Emacs fixnums.
17263 (Frecenter): Don't wrap around a line count if it is out of 'int'
17264 range; instead, treat it as an extreme value.
17265 (Fset_window_configuration, compare_window_configurations):
17266 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
17268 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
17269 that can exceed INT_MAX. Check that EMACS_INT value is in range
17270 before assigning it to the (possibly-narrower) index.
17271 (match_limit): Don't assume that a fixnum can fit in 'int'.
17273 * print.c (print_object): Use ptrdiff_t, not int, for index that can
17276 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
17277 (Fvertical_motion): Don't wrap around LINES values that don't fit
17278 in 'int'. Instead, treat them as extreme values. This is good
17279 enough for windows, which can't have more than INT_MAX lines anyway.
17281 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17283 * Require libxml/parser.h to avoid compilation warning.
17285 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
17287 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
17288 since this reportedly can destroy thread storage.
17290 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
17292 * syntax.c (find_defun_start): Update all cache variables if
17293 exiting early (Bug#9401).
17295 2011-08-30 Eli Zaretskii <eliz@gnu.org>
17297 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
17299 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
17300 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
17301 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
17303 * term.c (tty_append_glyph): New function.
17304 (produce_stretch_glyph): Static function and its prototype deleted.
17306 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
17309 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
17311 * image.c (parse_image_spec): Check for nonnegative, not for positive,
17312 when checking :margin (Bug#9390).
17313 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
17314 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
17315 so that the name doesn't mislead. All uses changed.
17317 2011-08-28 Johan Bockgård <bojohan@gnu.org>
17319 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
17322 2011-08-27 Eli Zaretskii <eliz@gnu.org>
17324 * xdisp.c (move_it_to): Don't bail out early when reaching
17325 position beyond to_charpos, if we are scanning backwards.
17326 (move_it_vertically_backward): When DY == 0, make sure we get to
17327 the first character in the line after the newline.
17329 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
17331 * ccl.c: Improve and simplify overflow checking (Bug#9196).
17332 (ccl_driver): Do not generate an out-of-range pointer.
17333 (Fccl_execute_on_string): Remove unnecessary check for
17334 integer overflow, noted by Stefan Monnier in
17335 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
17336 Remove a FIXME that didn't need fixing.
17337 Simplify the newly-introduced buffer reallocation code.
17339 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
17341 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
17343 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
17345 Integer and memory overflow issues (Bug#9196).
17347 * doc.c (get_doc_string): Rework so that
17348 get_doc_string_buffer_size is the actual buffer size, rather than
17349 being 1 less than the actual buffer size; this makes xpalloc more
17352 * image.c (x_allocate_bitmap_record, cache_image):
17353 * xselect.c (Fx_register_dnd_atom):
17354 Simplify previous changes by using xpalloc.
17356 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
17357 since either will do and ptrdiff_t is convenient with xpalloc.
17359 * charset.c (charset_table_size)
17360 (struct charset_sort_data.priority): Now ptrdiff_t.
17361 (charset_compare): Don't overflow if priorities differ greatly.
17362 (Fsort_charsets): Don't assume list length fits in int.
17363 Check for size-calculation overflow when allocating sort data.
17364 (syms_of_charset): Allocate an initial charset table that is
17365 just under 64 KiB, to avoid problems with glibc malloc and mmap.
17367 * cmds.c (internal_self_insert): Check for size-calculation overflow.
17369 * composite.h (struct composition.glyph_len): Now int, not unsigned.
17370 The actual value is always <= INT_MAX, and leaving it unsigned made
17371 overflow checking harder.
17373 * dispextern.h (struct glyph_matrix.rows_allocated)
17374 (struct face_cache.size): Now ptrdiff_t, for convenience in use
17375 with xpalloc. The values are still always <= INT_MAX.
17377 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
17379 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
17380 (SAFE_NALLOCA): New macro.
17382 * region-cache.c (struct boundary.pos, find_cache_boundary)
17383 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
17384 (set_cache_region, invalidate_region_cache)
17385 (revalidate_region_cache, know_region_cache, region_cache_forward)
17386 (region_cache_backward, pp_cache):
17387 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
17388 so that ptrdiff_t * can be passed to xpalloc.
17389 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
17390 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
17391 (pp_cache): Don't assume cache_len fits in int.
17392 * region-cache.h: Adjust extern decls to match.
17394 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
17395 EMACS_INT, since either will do, for xpalloc.
17397 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
17398 (xnmalloc, xnrealloc, xpalloc): New functions.
17400 * bidi.c (bidi_shelve_header_size): New constant.
17401 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
17402 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
17404 * bidi.c (bidi_cache_shrink):
17405 * buffer.c (overlays_at, overlays_in, record_overlay_string)
17407 Don't update size of array until after memory allocation succeeds,
17408 because xmalloc/xrealloc may not return.
17409 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
17410 now that we have proper integer overflow checking.
17411 (record_overlay_string, overlay_strings): Catch overflows when
17412 calculating size of overlay_str_buf.
17414 * callproc.c (Fcall_process): Check for size overflow when
17415 calculating size of args2.
17416 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
17417 Normally we prefer signed values, but sticking with ptrdiff_t would
17418 require adding more-complicated checks.
17420 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
17421 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
17422 Redo buffer-overflow calculations to avoid integer overflow.
17423 Add a FIXME comment where memory seems to be over-allocated.
17425 * character.c (Fstring): Check for size-calculation overflow.
17427 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
17428 unnecessary integer overflow. Check for size overflow.
17429 (encode_coding_object): Don't update size until xmalloc succeeds.
17431 * composite.c (get_composition_id): Check for overflow in glyph
17432 length calculations.
17434 Integer and memory overflow fixes for display code.
17435 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
17436 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
17437 (scrolling_window): Check for overflow in size calculations.

17442 (scrolling_window): Avoid overflow in size calculations.
17443 Don't update size until allocation succeeds.
17444 * fns.c (concat): Check for overflow in size calculations.
17445 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
17446 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

17449 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
17450 (get_doc_string): Check for size calculation overflow.
17451 Don't update size until allocation succeeds.
17452 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
17453 EMACS_INT, where ptrdiff_t will do.
17454 (Fsubstitute_command_keys): Check for string overflow.
17456 * editfns.c (set_time_zone_rule): Don't assume environment length
17458 (message_length): Now ptrdiff_t, not int.
17459 (Fmessage_box): Don't update size until allocation succeeds.
17460 Don't assume message length fits in int.
17461 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
17463 * emacs.c (main): Do not reallocate argv, since there is a null at
17464 the end that can be overwritten, and this way there's no need to
17465 worry about size-calculation overflow.
17466 (sort_args): Check for size-calculation overflow.
17468 * eval.c (init_eval_once, grow_specpdl): Don't update size until
17470 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
17472 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
17473 (x_set_scroll_bar_width, x_figure_window_size):
17474 Check for integer overflow.
17475 (x_set_alpha): Do not assume XINT fits in int.
17477 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
17478 This is for the members text_lines, text_cols, total_lines, total_cols,
17479 where the system imposes an 'int' limit.
17481 * fringe.c (Fdefine_fringe_bitmap):
17482 Don't update size until alloc works.
17484 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
17485 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
17487 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
17488 Check for size-calculation overflow.
17489 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
17490 do, as we prefer signed integers.
17491 (id_to_widget.max_size, id_to_widget.used)
17492 (xg_store_widget_in_map, xg_remove_widget_from_map)
17493 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
17494 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
17495 Use and return ptrdiff_t, not int.
17496 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
17497 * gtkutil.h: Change prototypes to match the above.
17499 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
17500 are duplicate now that they've been promoted to lisp.h.
17501 (x_allocate_bitmap_record, x_alloc_image_color)
17502 (make_image_cache, cache_image, xpm_load):
17503 Don't update size until alloc is done.

17514 Use ptrdiff_t, not int, to count maps.
17515 (read_char_minibuf_menu_prompt): Check for overflow in size
17516 calculations. Don't update size until allocation succeeds.
17517 Redo calculations to avoid overflow.
17518 * keyboard.h: Change prototypes to match the above.
17520 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
17522 (current_minor_maps): Check for size calculation overflow.
17523 * keymap.h: Change prototypes to match the above.

17531 Now ptrdiff_t, not int.
17532 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

17544 (Fset_match_data): Don't assume list lengths fit in 'int'.
17546 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
17547 for command line length. Do not attempt to address one before the
17548 beginning of an array, as that's not portable.
17550 * term.c (max_frame_lines): Remove; unused.
17551 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
17553 (encode_terminal_code, calculate_costs): Check for size
17554 calculation overflow.

17558 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
17560 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
17561 subtracting pointers.
17562 (gobble_line): Check for overflow more carefully. Don't update size
17565 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
17566 Don't update size until alloc done.
17567 Redo size calculations to avoid overflow.

17576 Use ptrdiff_t, not int, for sizes.
17577 (Finternal_make_lisp_face, cache_face):
17578 Check for size calculation overflow.
17579 (cache_face): Treat size calculation overflows as if they were
17580 memory exhaustion (the usual treatment), rather than aborting.
17582 * xfns.c (x_encode_text, x_set_name_internal)
17583 (Fx_change_window_property): Use ptrdiff_t, not int, to count
17584 sizes, since they can exceed INT_MAX in size. Check for size

17588 (xg_select): Check for size calculation overflow.
17589 Don't update size until alloc done.
17591 * xrdb.c (get_environ_db): Don't assume path length fits in int,
17592 as sprintf is limited to int lengths.
17594 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
17595 (X_LONG_MIN): New macros.
17596 Use them to make the following changes clearer.
17597 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
17598 This change doesn't affect the value now, but it may help remind
17599 future maintainers not to raise the value too much later.
17600 (SELECTION_QUANTUM): Remove, replacing with ...
17601 (selection_quantum): ... new function, which avoids overflow.
17603 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
17604 assumption that selection length fits in 'int'.
17605 (x_reply_selection_request, x_handle_selection_request)
17606 (x_get_window_property, receive_incremental_selection)
17607 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
17608 (lisp_data_to_selection_data, clean_local_selection_data):
17609 Use ptrdiff_t, not int, to record length of selection.

17612 Redo calculations to avoid overflow.
17613 (x_reply_selection_request): When sending hint, ceiling it at

17616 (x_get_window_property, receive_incremental_selection)
17617 (lisp_data_to_selection_data, x_property_data_to_lisp):
17618 Check for size-calculation overflow.
17619 (x_get_window_property, receive_incremental_selection)
17620 (lisp_data_to_selection_data, Fx_register_dnd_atom):
17621 Don't store size until memory allocation succeeds.
17622 (x_get_window_property): Plug memory leak on memory exhaustion.
17623 Don't double-block input; malloc is safe here. Don't assume 2**34
17624 - 4 fits in unsigned long. Add an xassert to check
17625 XGetWindowProperty overflow. Be more careful about overflow
17626 calculations, and distinguish size from memory overflow better.
17627 (receive_incremental_selection): When tracing, don't assume
17628 unsigned int is less than INT_MAX.
17629 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
17630 harmful) conversions of unsigned short to int.
17631 (lisp_data_to_selection_data): Don't assume that integers
17632 in the range -65535 through -1 fit in an X unsigned short.
17633 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17634 result parameters unless successful. Rely on cons_to_unsigned
17635 to report problems with elements; the old code wasn't right anyway.
17636 (x_check_property_data): Check for int overflow; we cannot use
17637 a wider type due to X limits.
17638 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
17640 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

17645 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
17646 Don't assume alloca size is less than MAX_ALLOCA.
17647 (x_term_init): Don't assume length fits in int (sprintf is limited
17650 Use ptrdiff_t for composition IDs.

17669 * image.c (xpm_get_color_table_h):
17670 * lisp.h (hash_lookup, hash_put):
17671 * minibuf.c (Ftest_completion):
17672 Use ptrdiff_t for hash table indexes, not int (which is too
17673 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17674 32-bit --with-wide-int hosts).
17676 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17677 Add a FIXME comment about memory leaks.
17678 (syms_of_charset): Don't assume xmalloc returns.
17680 Don't assume that stated character widths fit in int.

17682 * character.h (CHAR_WIDTH):
17683 * indent.c (MULTIBYTE_BYTES_WIDTH):
17684 Use sanitize_char_width to avoid undefined and/or bad behavior
17685 with outlandish widths.
17686 * character.h (sanitize_tab_width): Rename from sanitize_width,
17687 now that we have two such functions. All uses changed.
17688 (sanitize_char_width): New inline function.
17690 Don't assume that tab-width fits in int.
17691 * character.h (sanitize_width): New inline function.
17692 (SANE_TAB_WIDTH): New macro.
17693 (ASCII_CHAR_WIDTH): Use it.

17698 * fileio.c: Integer overflow issues with file modes.
17699 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
17701 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

17706 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17707 (x_send_scroll_bar_event): Likewise. Check that the size does not
17708 exceed limits imposed by XClientMessageEvent, as well as the usual
17709 ptrdiff_t and size_t limits.
17711 * keyboard.c: Overflow, signedness and related fixes.
17712 (make_lispy_movement): Use same integer type in forward decl
17713 that is used in the definition.
17714 (read_key_sequence, keyremap_step):
17715 Change bufsize argument back to int, undoing my 2011-03-30 change.
17716 We prefer signed types, and int is wide enough here.
17717 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17718 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17719 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17720 length, not size_t. Use ptrdiff_t for index, not int.
17721 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17722 possibility of integer overflow.
17724 Overflow, signedness and related fixes for images.
17726 * dispextern.h (struct it.stack[0].u.image.image_id)
17727 (struct_it.image_id, struct image.id, struct image_cache.size)

17734 * xdisp.c (calc_pixel_width_or_height):
17735 * xfns.c (image_cache_refcount):
17736 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
17737 on typical 64-bit hosts.

17745 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
17746 (lookup_image): Remove unnecessary tests.
17747 (xbm_image_p): Locals are now of int, not EMACS_INT,
17748 since parse_image_check makes sure they fit into int.
17749 (png_load, gif_load, svg_load_image):
17750 Prefer int to unsigned where either will do.
17751 (tiff_handler): New function, combining the cores of the
17752 old tiff_error_handler and tiff_warning_handler.
17753 This function is rewritten to use vsnprintf and thereby avoid
17754 stack buffer overflows. It uses only the features of vsnprintf
17755 that are common to both POSIX and native Microsoft.
17756 (tiff_error_handler, tiff_warning_handler): Use it.
17757 (tiff_load, gif_load, imagemagick_load_image):
17758 Don't assume :index value fits in 'int'.
17759 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17760 (imagemagick_load_image): Check that crop parameters fit into
17761 the integer types that MagickCropImage accepts. Don't assume
17762 Vimagemagick_render_type has a nonnegative value. Don't assume
17763 size_t fits in 'long'.
17764 (gs_load): Use printmax_t to print the widest integers possible.
17765 Check for integer overflow when computing image height and width.

17777 handle_single_display_spec, not just 1 or zero.
17778 (handle_single_display_spec): If the display spec is of the form
17779 `(space ...)', and specifies display in the text area, return 2
17781 (try_cursor_movement): Check for the need to scroll more
17782 accurately, and prefer exact match for point under bidi.
17783 Don't advance `row' beyond the last row of the window.
17785 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
17786 into disp_prop; all users changed.

17801 buffers, return left-to-right.
17802 (set_cursor_from_row): Consider candidate row a win if its glyph
17803 represents a newline and point is on that newline. Fixes cursor
17804 positioning on the newline at EOL of R2L text within L2R
17805 paragraph, and vice versa.
17806 (try_cursor_movement): Check continued rows, in addition to
17807 continuation rows. Fixes unwarranted scroll when point enters a
17808 continued line of R2L text within an L2R paragraph, or vice versa.
17809 (cursor_row_p): Consider the case of point being equal to
17810 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

17836 * xdisp.c (redisplay_window): When computing centering_position,
17837 account for the height of the header line. (Bug#8874)
17839 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17840 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17841 candidate is selected by the mouse, and that candidate has a
17842 composed character under the mouse.
17844 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17845 coordinates reported by pos-visible-in-window-p for a composed
17846 character in column zero.

17855 consider it a hit if to_charpos is anywhere in the range of the
17856 composed buffer positions.
17858 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17860 * image.c (gif_load): Don't assume that each subimage has the same
17861 dimensions as the base image. Handle disposal method that is
17862 "undefined" by the gif spec (Bug#9335).

17872 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17873 from an Org mode buffer to a Speedbar frame.
17875 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17876 a composition, take its buffer position from IT->cmp_it.charpos.
17877 Fixes cursor positioning at the beginning of a line that begins
17878 with a composed character.
17880 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17882 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17883 character bidirectional type, use STRONG_L instead. Fixes crashes
17884 in a buffer produced by `describe-categories'.
17886 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17887 members before the level stack, so they would be saved and
17888 restored when copying iterator state. Fixes incorrect reordering
17889 around TABs covered by display properties.

18025 the iterator structure wrt the object coming from a display
18026 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
18027 properties. (Bug#9284)

18230 * nsterm.m (ns_draw_text_decoration): New function for drawing
18231 underline, overline, and strike-through.
18232 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
18233 ns_draw_text_decoration. Change treatment of cursor drawing to
18234 accommodate underlining, etc.
18236 2011-07-28 Eli Zaretskii <eliz@gnu.org>
18238 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
18241 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18243 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
18244 Without this fix, if a signal arrives just after memory fills up,
18245 'malloc' might be invoked reentrantly.
18247 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
18248 In other words, assume that every image size is allowed, on non-X
18249 hosts. This assumption is probably wrong, but it lets Emacs compile.
18251 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18253 * regex.c (re_iswctype): Convert return values to boolean.
18255 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
18257 * xdisp.c (compute_display_string_pos): Don't use cached display
18258 string position if the buffer had its restriction changed.
18261 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18263 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18265 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18267 Integer signedness and overflow and related fixes. (Bug#9079)
18269 * bidi.c: Integer size and overflow fixes.
18270 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
18271 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
18272 (bidi_cache_find_level_change, bidi_cache_ensure_space)
18273 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
18274 (bidi_find_other_level_edge):
18275 Use ptrdiff_t instead of EMACS_INT where either will do.
18276 This works better on 32-bit hosts configured --with-wide-int.
18277 (bidi_cache_ensure_space): Check for size-calculation overflow.
18278 Use % rather than repeated addition, for better worst-case speed.
18279 Don't set bidi_cache_size until after xrealloc returns, because it
18281 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
18282 (bidi_cache_ensure_space): Also check that the bidi cache size
18283 does not exceed that of the largest Lisp string or buffer. See Eli
18284 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
18286 * alloc.c (__malloc_size_t): Remove.
18287 All uses replaced by size_t. See Andreas Schwab's note
18288 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
18290 * image.c: Improve checking for integer overflow.
18291 (check_image_size): Assume that f is nonnull, since
18292 it is always nonnull in practice. This is one less thing to
18293 worry about when checking for integer overflow later.
18294 (x_check_image_size): New function, which checks for integer
18295 overflow issues inside X.
18296 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
18297 This removes the need for a memory_full check.
18298 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
18299 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
18300 (xbm_read_bitmap_data): Change locals back to 'int', since
18301 their values must fit in 'int'.
18302 (xpm_load_image, png_load, tiff_load):
18303 Invoke x_create_x_image_and_pixmap earlier,
18304 to avoid much needless work if the image is too large.
18305 (tiff_load): Treat overly large images as if
18306 x_create_x_image_and_pixmap failed, not as malloc failures.
18307 (gs_load): Use x_check_image_size.
18309 * gtkutil.c: Omit integer casts.
18310 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
18311 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
18313 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
18315 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
18316 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
18317 would wrongly return t on a 64-bit host.
18319 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
18320 The plain *_OVERFLOW macros run afoul of GCC bug 49705
18321 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
18322 and therefore cause GCC to emit a bogus diagnostic in some cases.
18324 * image.c: Integer signedness and overflow and related fixes.
18325 This is not an exhaustive set of fixes, but it's time to
18326 record what I've got.
18327 (lookup_pixel_color, check_image_size): Remove redundant decls.
18328 (check_image_size): Don't assume that arbitrary EMACS_INT values
18329 fit in 'int', or that arbitrary 'double' values fit in 'int'.
18330 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
18331 (tiff_load, imagemagick_load_image):
18332 Check for overflow in size calculations.
18333 (x_create_x_image_and_pixmap): Remove unnecessary test for
18334 xmalloc returning NULL; that can't happen.
18335 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
18336 (xpm_color_bucket): Use better integer hashing function.
18337 (xpm_cache_color): Don't possibly over-allocate memory.
18338 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
18339 (gif_memory_source):
18340 Use ptrdiff_t, not int or size_t, to record sizes.
18341 (png_load): Don't assume values greater than 2**31 fit in 'int'.
18342 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
18343 either works, as we prefer signed integers.
18344 (tiff_read_from_memory, tiff_write_from_memory):
18345 Return tsize_t, not size_t, since that's what the TIFF API wants.
18346 (tiff_read_from_memory): Don't fail simply because the read would
18347 go past EOF; instead, return a short read.
18348 (tiff_load): Omit no-longer-needed casts.
18349 (Fimagemagick_types): Don't assume size fits into 'int'.
18351 Improve hashing quality when configured --with-wide-int.
18352 * fns.c (hash_string): New function, taken from sxhash_string.
18353 Do not discard information about ASCII character case; this
18354 discarding is no longer needed.
18355 (sxhash-string): Use it. Change sig to match it. Caller changed.
18356 * lisp.h: Declare it.
18357 * lread.c (hash_string): Remove, since we now use fns.c's version.
18358 The fns.c version returns a wider integer if --with-wide-int is
18359 specified, so this should help the quality of the hashing a bit.
18361 * emacs.c: Integer overflow minor fix.
18362 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
18363 Define only if GNU_LINUX.
18364 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
18366 * dispnew.c: Integer signedness and overflow fixes.
18367 Remove unnecessary forward decls, that were a maintenance hassle.
18368 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
18370 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
18371 (scrolling_window): Use ptrdiff_t, not int, for byte count.
18372 (prepare_desired_row, line_draw_cost):
18373 Use int, not unsigned, where either works.
18374 (save_current_matrix, restore_current_matrix):
18375 Use ptrdiff_t, not size_t, where either works.
18376 (init_display): Check for overflow more accurately, and without
18377 relying on undefined behavior.
18379 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
18380 Remove, replacing with the new symbols in lisp.h. All uses changed.
18381 * fileio.c (make_temp_name):
18382 * filelock.c (lock_file_1, lock_file):
18383 * xdisp.c (message_dolog):
18384 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
18385 Use pMd etc. instead.
18386 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
18387 replacing the pWIDE etc. symbols removed from editfns.c.
18389 * keyboard.h (num_input_events): Now uintmax_t.
18390 This is (very slightly) less likely to mess up due to wraparound.
18393 * buffer.c: Integer signedness fixes.
18394 (alloc_buffer_text, enlarge_buffer_text):
18395 Use ptrdiff_t rather than size_t when either will do, as we prefer
18398 * alloc.c: Integer signedness and overflow fixes.
18399 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
18400 (__malloc_size_t): Default to size_t, not to int.
18401 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
18402 (Fgarbage_collect, mark_object_loop_halt, mark_object):
18403 Prefer ptrdiff_t to size_t when either would do, as we prefer
18405 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
18406 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
18407 Now const. Initialize with values that are in range even if char
18409 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
18410 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
18411 These functions do the right thing with sizes > 2**32.
18412 (check_depth): Now ptrdiff_t, not int.
18413 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
18414 Adjust to new way of storing sizes. Check for size overflow bugs
18416 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
18417 slightly wrong anyway, as it missed one instance of
18418 XMALLOC_OVERRUN_CHECK_OVERHEAD.
18419 (refill_memory_reserve): Omit needless cast to size_t.
18420 (mark_object_loop_halt): Mark as externally visible.
18422 * xselect.c: Integer signedness and overflow fixes.
18423 (Fx_register_dnd_atom, x_handle_dnd_message):
18424 Use ptrdiff_t, not size_t, since we prefer signed.
18425 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
18426 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
18427 x_dnd_atoms_size and x_dnd_atoms_length.
18429 * doprnt.c: Prefer signed to unsigned when either works.
18431 * doprnt.c (doprnt):
18433 * xdisp.c (vmessage):
18434 Use ptrdiff_t, not size_t, when using or implementing doprnt,
18435 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
18436 prefer signed arithmetic to avoid comparison confusion.
18437 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
18438 but is a bit tricky.
18440 Assume freestanding C89 headers, string.h, stdlib.h.
18441 * data.c, doprnt.c, floatfns.c, print.c:
18442 Include float.h unconditionally.
18443 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
18444 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
18445 * regex.c: Likewise for stddef.h, string.h.
18446 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
18447 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
18448 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
18449 (STDC_HEADERS): Remove obsolete defines.
18450 * sysdep.c: Include limits.h unconditionally.
18452 Assume support for memcmp, memcpy, memmove, memset.
18453 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
18454 * regex.c (memcmp, memcpy):
18455 Remove; we assume C89 now.
18457 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
18458 (__malloc_safe_bcopy): Remove; no longer needed.
18460 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
18461 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
18462 well either way, and we prefer signed to unsigned.
18464 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
18466 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
18467 closes the connection while we're reading (bug#9182).
18469 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
18471 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
18472 are specified (Bug#9168).
18474 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
18476 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
18477 Found by GCC static checking and --with-wide-int on a 32-bit host.
18479 2011-07-25 Eli Zaretskii <eliz@gnu.org>
18481 * xdisp.c (compute_display_string_pos): Fix logic of caching
18482 previous display string position. Initialize cached_prev_pos to
18483 -1. Fixes slow-down at the beginning of a buffer.
18485 2011-07-24 Eli Zaretskii <eliz@gnu.org>
18487 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
18488 for attrs[LFACE_FONTSET_INDEX].
18490 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
18492 * xml.c (parse_region): Remove unused local
18493 that was recently introduced.
18495 2011-07-23 Eli Zaretskii <eliz@gnu.org>
18497 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
18498 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
18500 * xdisp.c (move_it_in_display_line_to): Record the best matching
18501 position for TO_CHARPOS while scanning the line, and restore it on
18502 exit if none of the characters scanned was an exact match.
18503 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
18504 when exact match is impossible due to invisible text, and the
18505 lines are truncated.
18507 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
18509 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
18512 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18514 Fix a significant slow-down of cursor motion with C-n, C-p,
18515 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
18516 auto-repeat under bidi redisplay in fontified buffers.
18517 * xdisp.c (compute_stop_pos_backwards): New function.
18518 (next_element_from_buffer): Call compute_stop_pos_backwards to
18519 find a suitable prev_stop when we find ourselves before
18521 (reseat): Don't look for prev_stop, as that could mean a very long
18523 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
18524 <cached_disp_overlay_modiff>: Cache for last found display string
18526 (compute_display_string_pos): Return the cached position if asked
18527 about the same buffer in the same area of character positions, and
18528 the buffer wasn't changed since the time the display string
18529 position was cached.
18531 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18533 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
18534 is an integer, which is important for empty lines. (Bug#9149)
18536 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
18538 * frame.c (Fmodify_frame_parameters): In tty case, update the
18539 default face if necessary (Bug#4238).
18541 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
18543 * editfns.c (Fstring_to_char): No need to explain what a character
18544 is in the docstring (Bug#6576).
18546 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18548 * xml.c (parse_region): Make sure we always return a tree.
18550 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
18552 * xml.c (parse_region): If a document contains only comments,
18555 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18557 * xml.c (make_dom): Return comments, too.
18559 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
18562 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
18563 and the surrounding thread.
18564 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
18565 rather than fgets, and retry after EINTR. Otherwise, 'emacs
18566 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
18568 * s/openbsd.h (BROKEN_SIGIO): Define.
18569 * unexelf.c (unexec) [__OpenBSD__]:
18570 Don't update the .mdebug section of the Alpha COFF symbol table.
18572 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
18574 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
18577 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
18579 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
18580 This fixes some race conditions on the permissions of any newly
18583 * alloc.c (valid_pointer_p): Use pipe, not open.
18584 This fixes some permissions issues when debugging.
18586 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
18587 If fchown fails to set both uid and gid, try to set just gid,
18588 as that is sometimes allowed. Adjust the file's mode to eliminate
18589 setuid or setgid bits that are inappropriate if fchown fails.
18591 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
18593 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
18594 to compare Lisp_Objects.
18595 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
18596 global_gnutls_log_level, don't mistake it for a Lisp_Object.
18597 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
18599 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
18601 * lread.c (read_integer): Unread even EOF character.
18602 (read1): Likewise. Properly record start position of symbol.
18604 * lread.c (read1): Read `#:' as empty uninterned symbol if no
18605 symbol character follows.
18607 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
18609 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
18610 This works around a problem with the previous change to Fcopy_file.
18611 Recent glibc declares fchown with __attribute__((warn_unused_result)),
18612 and without this change, GCC might complain about discarding
18613 fchown's return value.
18615 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
18617 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
18619 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
18621 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
18623 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
18625 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
18626 it's used from the C level.
18628 * process.c: Use the same condition for POLL_FOR_INPUT in both
18629 keyboard.c and process.c (bug#1858).
18631 2011-07-09 Lawrence Mitchell <wence@gmx.li>
18633 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
18634 (Fgnutls_boot): Use it.
18636 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
18638 * doc.c (Fsubstitute_command_keys): Revert last change.
18640 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18642 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18643 quotes the next character, and doesn't affect other longer
18644 sequences (bug#8935).
18646 * lread.c (syms_of_lread): Clarify that is isn't only
18647 `eval-buffer' and `eval-defun' that's affected by
18648 `lexical-binding' (bug#8460).
18650 2011-07-15 Eli Zaretskii <eliz@gnu.org>
18652 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18653 bidi redisplay when a line includes both an image and is truncated.
18655 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18657 Fix minor problems found by static checking.
18658 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18659 (elsz): Now a signed constant, not a size_t var. We prefer signed
18660 types to unsigned, to avoid integer comparison confusion. Without
18661 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18662 "cannot optimize loop, the loop counter may overflow", a symptom
18664 * indent.c (Fvertical_motion): Mark locals as initialized.
18665 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18667 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

19193 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

19230 Random fixes. E.g., (random) never returned negative values.
19231 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
19232 subseconds part to the entropy, as that's a bit more random.
19233 Prefer signed to unsigned, since the signedness doesn't matter and
19234 in general we prefer signed. When given a limit, use a
19235 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
19236 latter isn't right if USE_2_TAGS_FOR_INTS.
19237 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
19238 not 0..VALMASK. Don't discard "excess" bits that random () returns.

19250 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
19251 This is more efficient than Ffile_directory_p and avoids a minor race.

19255 * buffer.c (Foverlay_put): Say what the return value is
19258 * fileio.c (barf_or_query_if_file_exists): Check first if the file

19262 error be more correct.
19264 * fns.c (Frequire): Remove the mention of the .gz files, since

19278 Qgnutls_bootprop_verify_error (which is no longer used).
19280 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
19281 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
19282 Also (re)move comments that are misplaced or no longer relevant.
19284 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
19286 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

19311 * lread.c (syms_of_lread): Mention single symbols defined by

19345 (syms_of_keymap): Defsubr make-composed-keymap.
19346 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

19383 * eval.c (struct backtrace): Simplify and port the data structure.
19384 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
19385 signed bit field, as this assumption is not portable and it makes
19386 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
19387 "char debug_on_exit : 1" as this is not portable either; instead,
19388 use the portable "unsigned int debug_on_exit : 1". Remove unused
19389 member evalargs. Remove obsolete comments about cc bombing out.
19391 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

19545 * xmenu.c (syms_of_xmenu):
19546 * xsettings.c (syms_of_xsettings):
19547 * xterm.c (syms_of_xterm): Use DEFSYM.
19549 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
19551 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
19553 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
19555 Integer and buffer overflow fixes (Bug#8873).
19557 * print.c (printchar, strout): Check for string overflow.
19558 (PRINTPREPARE, printchar, strout):
19559 Don't set size unless allocation succeeds.
19561 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
19562 for sizes. Check for string overflow more accurately.
19563 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
19565 * macros.c: Integer and buffer overflow fixes.
19566 * keyboard.h (struct keyboard.kbd_macro_bufsize):
19567 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
19568 Use ptrdiff_t, not int, for sizes.
19569 Don't increment bufsize until after realloc succeeds.
19570 Check for size-calculation overflow.
19571 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
19573 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
19575 * lread.c: Integer overflow fixes.
19576 (read_integer): Radix is now EMACS_INT, not int,
19577 to improve quality of diagnostics for out-of-range radices.
19578 Calculate buffer size correctly for out-of-range radices.
19579 (read1): Check for integer overflow in radices, and in
19580 read-circle numbers.
19581 (read_escape): Avoid int overflow.
19582 (Fload, openp, read_buffer_size, read1)
19583 (substitute_object_recurse, read_vector, read_list, map_obarray):
19584 Use ptrdiff_t, not int, for sizes.
19585 (read1): Use EMACS_INT, not int, for sizes.
19586 Check for size overflow.
19588 * image.c (cache_image): Check for size arithmetic overflow.
19590 * lread.c: Integer overflow issues.
19591 (saved_doc_string_size, saved_doc_string_length)
19592 (prev_saved_doc_string_size, prev_saved_doc_string_length):
19593 Now ptrdiff_t, not int.
19594 (read1): Don't assume doc string length fits in int. Check for
19595 out-of-range doc string lengths.

19597 (read_escape): Check for hex character overflow.
19599 2011-06-22 Leo Liu <sdl.web@gmail.com>
19601 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
19602 Move to minibuffer.el.
19604 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19606 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
19607 The following patches are for when GLYPH_DEBUG && !XASSERT.
19608 * dispextern.h (trace_redisplay_p, dump_glyph_string):
19609 * dispnew.c (flush_stdout):
19610 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
19611 Mark as externally visible.
19612 * dispnew.c (check_window_matrix_pointers): Now static.
19613 * dispnew.c (window_to_frame_vpos):
19614 * xfns.c (unwind_create_frame):
19615 * xterm.c (x_check_font): Remove unused local.
19616 * scroll.c (CHECK_BOUNDS):
19617 * xfaces.c (cache_fache): Rename local to avoid shadowing.
19618 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
19619 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
19620 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
19621 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
19623 (debug_method_add): Use va_list and vsprintf rather than relying
19624 on undefined behavior with wrong number of arguments.
19625 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19626 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19627 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19628 since we're not interested in debugging glyphs with old libraries.
19629 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19630 GCC 4.6.0's static checking.
19632 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19634 Integer overflow and signedness fixes (Bug#8873).
19635 A few related buffer overrun fixes, too.

19641 (x_bitmap_mask, x_allocate_bitmap_record)
19642 (x_create_bitmap_from_data, x_create_bitmap_from_file)
19643 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
19644 (x_create_bitmap_from_xpm_data):
19645 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
19646 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
19648 * xfaces.c (load_pixmap):
19649 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
19650 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
19651 (.bitmaps_last, struct x_output.icon_bitmap):
19652 Use ptrdiff_t, not int, for bitmap indexes.
19653 (x_allocate_bitmap_record): Check for size overflow.
19654 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
19656 Use ptrdiff_t, not int, for overlay counts.
19657 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
19658 * editfns.c (overlays_around, get_pos_property):
19659 * textprop.c (get_char_property_and_overlay):
19660 * xdisp.c (next_overlay_change, note_mouse_highlight):
19661 * xfaces.c (face_at_buffer_position):
19662 * buffer.c (OVERLAY_COUNT_MAX): New macro.
19663 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
19664 (Fnext_overlay_change, Fprevious_overlay_change)
19665 (mouse_face_overlay_overlaps, Foverlays_in):
19666 Use ptrdiff_t, not int, for sizes.
19667 (overlays_at, overlays_in): Check for size-calculation overflow.
19669 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19671 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19672 (x_session_initialize): Do not assume string length fits in int.
19674 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19675 This is unlikely, but can occur if DPI is outlandish.
19677 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19678 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19680 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
19681 * xrdb.c (magic_file_p, search_magic_path):
19682 Omit last arg SUFFIX; it was always 0. All callers changed.
19683 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
19685 * xfont.c (xfont_match): Avoid need for strlen.
19687 * xfns.c: Don't assume strlen fits in int.
19688 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
19690 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19691 not unsigned long, as we prefer signed integers. All callers changed.
19692 Detect integer overflow in repeat count.
19693 (message_dolog): Don't assume print length fits in 39 bytes.
19694 (display_mode_element): Don't assume strlen fits in int.
19696 * termcap.c: Don't assume sizes fit in int and never overflow.
19697 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
19698 (gobble_line): Check for size-calculation overflow.
19700 * minibuf.c (Fread_buffer):
19701 * lread.c (intern, intern_c_string):
19702 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
19703 Don't assume string length fits in int.
19705 * keyboard.c (parse_tool_bar_item):
19706 * gtkutil.c (style_changed_cb): Avoid need for strlen.
19708 * font.c: Don't assume string length fits in int.
19709 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
19710 Use ptrdiff_t, not int.
19711 (font_intern_prop): Don't assume string length fits in int.
19712 Don't assume integer property fits in fixnum.
19713 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19715 * filelock.c: Fix some buffer overrun and integer overflow issues.
19716 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19717 Reformulate so as not to need the command string.
19718 Invoke gzip -cd rather than gunzip, as it's more portable.
19719 (lock_info_type, lock_file_1, lock_file):
19720 Don't assume pid_t and time_t fit in unsigned long.
19721 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19722 (current_lock_owner): Prefer signed type for sizes.
19723 Use memcpy, not strncpy, where memcpy is what is really wanted.
19724 Don't assume (via atoi) that time_t and pid_t fit in int.
19725 Check for time_t and/or pid_t out of range, e.g., via a network share.
19726 Don't alloca where an auto var works fine.
19728 * fileio.c: Fix some integer overflow issues.
19729 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19730 Don't assume string length fits in int.
19731 (directory_file_name): Don't assume string length fits in long.
19732 (make_temp_name): Don't assume pid fits in int, or that its print
19733 length is less than 20.
19735 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19737 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19739 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19741 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19742 We prefer signed integers, even for size calculations.
19744 * emacs.c: Don't assume string length fits in 'int'.
19745 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19746 (main): Don't invoke strlen when not needed.
19748 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
19749 (XD_DEBUG_MESSAGE): Don't waste a byte.
19751 * callproc.c (getenv_internal_1, getenv_internal)
19752 (Fgetenv_internal):
19753 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19755 * lread.c (invalid_syntax): Omit length argument.
19756 All uses changed. This doesn't fix a bug, but it simplifies the
19757 code away from its former Hollerith-constant appearance, and it's
19758 one less 'int' to worry about when looking at integer-overflow issues.
19759 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19761 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19762 This didn't break anything, but it didn't help either.
19763 It's confusing to put a bogus integer in a place where the actual
19764 value does not matter.
19765 (LIST_END_P): Remove unused macro and its bogus comment.
19766 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19768 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19769 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19771 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19772 We prefer signed types, and the value cannot exceed the EMACS_INT
19773 range anyway (because otherwise the length would not be representable).
19774 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19775 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19776 This avoids a GCC warning when WIDE_EMACS_INT.
19778 * indent.c (sane_tab_width): New function.
19779 (current_column, scan_for_column, Findent_to, position_indentation)
19780 (compute_motion): Use it. This is just for clarity.
19781 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19783 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19785 * lisp.h (lint_assume): New macro.
19786 * composite.c (composition_gstring_put_cache):
19787 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19789 * editfns.c, insdel.c:
19790 Omit unnecessary forward decls, to simplify future changes.
19792 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19794 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19796 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19797 Use much-faster test for byte-length change.
19798 Don't assume string byte-length fits in 'int'.
19799 Check that character arg fits in 'int'.
19800 (mapcar1): Declare byte as byte, for clarity.
19802 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19804 * fns.c (concat): Catch string overflow earlier.
19805 Do not rely on integer wraparound.
19807 * dispextern.h (struct it.overlay_strings_charpos)
19808 (struct it.selective): Now EMACS_INT, not int.
19809 * xdisp.c (forward_to_next_line_start)
19810 (back_to_previous_visible_line_start)
19811 (reseat_at_next_visible_line_start, next_element_from_buffer):
19812 Don't arbitrarily truncate the value of 'selective' to int.
19814 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19816 * composite.c: Don't truncate sizes to 'int'.
19817 (composition_gstring_p, composition_reseat_it)
19818 (composition_adjust_point): Use EMACS_INT, not int.
19819 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19820 not EMACS_UINT, for indexes.
19822 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19824 * buffer.c: Include <verify.h>.
19825 (struct sortvec.priority, struct sortstr.priority):
19826 Now EMACS_INT, not int.
19827 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19828 (struct sortstr.size, record_overlay_string)
19829 (struct sortstrlist.size, struct sortlist.used):
19830 Don't truncate size to int.
19831 (record_overlay_string): Check for size-calculation overflow.
19832 (init_buffer_once): Check at compile-time, not run-time.
19834 2011-06-22 Jim Meyering <meyering@redhat.com>
19836 Don't leak an XBM-image-sized buffer
19837 * image.c (xbm_load): Free the image buffer after using it.
19839 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19842 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19843 that Sun C diagnosed.
19844 * fns.c (secure_hash): Fix pointer signedness issue.
19845 * intervals.c (static_offset_intervals): New function.
19846 (offset_intervals): Use it.
19848 2011-06-21 Leo Liu <sdl.web@gmail.com>
19851 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19854 * fns.c (secure_hash): Rename from crypto_hash_function and change
19855 the first arg to accept symbols.
19856 (Fsecure_hash): New primitive.
19857 (syms_of_fns): New symbols.
19859 2011-06-20 Deniz Dogan <deniz@dogan.se>
19861 * process.c (Fset_process_buffer): Clarify return value in
19864 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19866 * dispnew.c (add_window_display_history): Use BVAR.
19868 * xdisp.c (debug_method_add): Use BVAR.
19869 (check_window_end, dump_glyph_matrix, dump_glyph)
19870 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19872 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19875 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19876 check till after the cache is created in init_frame_faces.
19878 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19880 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19882 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19884 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19885 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19886 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19888 Improve buffer-overflow checking (Bug#8873).
19889 * fileio.c (Finsert_file_contents):
19890 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19891 Remove the old (too-loose) buffer overflow checks.
19892 They weren't needed, since make_gap checks for buffer overflow.
19893 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19894 The old code merely checked for Emacs fixnum overflow, and relied
19895 on undefined (wraparound) behavior. The new code avoids undefined
19896 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19898 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19899 Tune. Don't use wider integers than needed. Don't use alloca.
19900 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19902 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19904 * insdel.c, lisp.h (buffer_overflow): New function.
19905 (insert_from_buffer_1, replace_range, replace_range_2):
19906 * insdel.c (make_gap_larger):
19907 * editfns.c (Finsert_char):
19908 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19910 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19912 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19914 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19916 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19917 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19919 * fileio.c: Don't assume EMACS_INT fits in off_t.
19920 (emacs_lseek): New static function.
19921 (Finsert_file_contents, Fwrite_region): Use it.
19922 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19924 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19926 * fns.c: Don't overflow int when computing a list length.
19927 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19928 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19929 truncation on 64-bit hosts. Check for QUIT every
19930 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19931 faster and is responsive enough.
19932 (Flength): Report an error instead of overflowing an integer.
19933 (Fsafe_length): Return a float if the value is not representable
19934 as a fixnum. This shouldn't happen except in contrived situations.
19935 (Fnthcdr, Fsort): Don't assume list length fits in int.
19936 (Fcopy_sequence): Don't assume vector length fits in int.
19938 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19939 (header_size, word_size): New constants.
19940 (allocate_vectorlike): Don't check size overflow here.
19941 (allocate_vector): Check it here instead, since this is the only
19942 caller of allocate_vectorlike that could cause overflow.
19943 Check that the new vector's length is representable as a fixnum.
19945 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19946 The previous code was bogus. For example, next_almost_prime (32)
19947 returned 39, which is undesirable as it is a multiple of 3; and
19948 next_almost_prime (24) returned 25, which is a multiple of 5 so
19949 why was the code bothering to check for multiples of 7?
19951 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19953 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19955 Variadic C functions now count arguments with ptrdiff_t.
19956 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19957 Back then I didn't know that the Emacs coding style prefers signed int.
19958 Also, in the meantime I found a few more instances where arguments
19959 were being counted with int, which may truncate counts on 64-bit
19960 machines, or EMACS_INT, which may be unnecessarily wide.
19961 * lisp.h (struct Lisp_Subr.function.aMANY)
19962 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19963 Arg counts are now ptrdiff_t, not size_t.
19964 All variadic functions and their callers changed accordingly.
19965 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19966 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19967 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19968 * callint.c (Fcall_interactively): Check arg count for overflow,
19969 to avoid potential buffer overrun. Use signed char, not 'int',
19970 for 'varies' array, so that we needn't bother to check its size
19971 calculation for overflow.
19972 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19973 * eval.c (apply_lambda):
19974 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19975 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19976 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19978 * callint.c (Fcall_interactively): Don't use index var as event count.
19980 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19981 * mem-limits.h (SIZE): Remove; no longer used.
19983 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19985 Remove unnecessary casts.
19986 * xterm.c (x_term_init):
19987 * xfns.c (x_set_border_pixel):
19988 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19989 These aren't needed now that we assume ANSI C.
19991 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19992 It's more likely to cause problems (due to unsigned overflow)
19995 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19997 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19999 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
20001 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
20003 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
20005 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
20007 GLYPH_CODE_FACE returns EMACS_INT, not int.
20008 * dispextern.h (merge_faces):
20009 * xfaces.c (merge_faces):
20010 * xdisp.c (get_next_display_element, next_element_from_display_vector):
20011 Don't assume EMACS_INT fits in int.
20013 * character.h (CHAR_VALID_P): Remove unused parameter.
20014 * fontset.c, lisp.h, xdisp.c: All uses changed.
20016 * editfns.c (Ftranslate_region_internal): Omit redundant test.
20018 * fns.c (concat): Minor tuning based on overflow analysis.
20019 This doesn't fix any bugs. Use int to hold character, instead
20020 of constantly refetching from Emacs object. Use XFASTINT, not
20021 XINT, for value known to be a character. Don't bother comparing
20022 a single byte to 0400, as it's always less.
20024 * floatfns.c (Fexpt):
20025 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
20027 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
20030 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
20032 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
20033 Without this fix, on a 64-bit host (aset S 0 4294967386) would
20034 incorrectly succeed when S was a string, because 4294967386 was
20035 truncated before it was used.
20037 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
20038 Otherwise, an out-of-range integer could cause undefined behavior
20041 * composite.c: Use int, not EMACS_INT, for characters.
20042 (fill_gstring_body, composition_compute_stop_pos): Use int, not
20043 EMACS_INT, for values that are known to be in character range.
20044 This doesn't fix any bugs but is the usual style inside Emacs and
20045 may generate better code on 32-bit machines.
20047 Make sure a 64-bit char is never passed to ENCODE_CHAR.
20048 This is for reasons similar to the recent CHAR_STRING fix.
20049 * charset.c (Fencode_char): Check that character arg is actually
20050 a character. Pass an int to ENCODE_CHAR.
20051 * charset.h (ENCODE_CHAR): Verify that the character argument is no
20052 wider than 'int', as a compile-time check to prevent future regressions
20055 * character.c (char_string): Remove unnecessary casts.
20057 Make sure a 64-bit char is never passed to CHAR_STRING.
20058 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
20059 by silently ignoring the top 32 bits, allowing some values
20060 that were far too large to be valid characters.
20061 * character.h: Include <verify.h>.
20062 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
20063 arguments are no wider than unsigned, as a compile-time check
20064 to prevent future regressions in this area.
20066 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
20067 (Fsubst_char_in_region):
20069 * xdisp.c (decode_mode_spec_coding):
20070 Adjust to CHAR_STRING's new requirement.
20071 * editfns.c (Finsert_char, Fsubst_char_in_region):
20072 * fns.c (concat): Check that character args are actually
20073 characters. Without this test, these functions did the wrong
20074 thing with wildly out-of-range values on 64-bit hosts.
20076 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
20077 These casts should not be needed on 32-bit hosts, either.
20078 * keyboard.c (read_char):
20079 * lread.c (Fload): Remove casts to unsigned.
20081 * lisp.h (UNSIGNED_CMP): New macro.
20082 This fixes comparison bugs on 64-bit hosts.
20083 (ASCII_CHAR_P): Use it.
20084 * casefiddle.c (casify_object):
20085 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
20086 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
20087 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
20088 * dispextern.h (FACE_FROM_ID):
20089 * keyboard.c (read_char): Use UNSIGNED_CMP.
20091 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
20092 not to EMACS_INT, to avoid GCC warning.
20094 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
20096 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
20097 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
20098 isn't needed on 32-bit machines.
20100 * buffer.c (Fgenerate_new_buffer_name):
20101 Use EMACS_INT for count, not int.
20102 (advance_to_char_boundary): Return EMACS_INT, not int.
20104 * data.c (Qcompiled_function): Now static.
20106 * window.c (window_body_lines): Now static.
20108 * image.c (gif_load): Rename local to avoid shadowing.
20110 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
20111 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
20112 * alloc.c (make_save_value): Integer argument is now of type
20113 ptrdiff_t, not int.
20114 (mark_object): Use ptrdiff_t, not int.
20115 * lisp.h (pD): New macro.
20116 * print.c (print_object): Use it.
20118 * alloc.c: Use EMACS_INT, not int, to count objects.
20119 (total_conses, total_markers, total_symbols, total_vector_size)
20120 (total_free_conses, total_free_markers, total_free_symbols)
20121 (total_free_floats, total_floats, total_free_intervals)
20122 (total_intervals, total_strings, total_free_strings):
20123 Now EMACS_INT, not int. All uses changed.
20124 (Fgarbage_collect): Compute overall total using a double, so that
20125 integer overflow is less likely to be a problem. Check for overflow
20126 when converting back to an integer.
20127 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
20128 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
20129 These were 'int' variables that could overflow on 64-bit hosts;
20130 they were never used, so remove them instead of repairing them.
20131 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
20132 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
20133 Previously, this ceilinged at INT_MAX, but that doesn't work on
20135 (allocate_pseudovector): Don't use EMACS_INT when int would do.
20137 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
20138 (allocate_vectorlike): Check for ptrdiff_t overflow.
20139 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
20140 when a (possibly-narrower) signed value would do just as well.
20141 We prefer using signed arithmetic, to avoid comparison confusion.
20143 * alloc.c: Catch some string size overflows that we were missing.
20144 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
20145 for convenience in STRING_BYTES_MAX.
20146 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
20147 The definition here is exact; the one in lisp.h was approximate.
20148 (allocate_string_data): Check for string overflow. This catches
20149 some instances we weren't catching before. Also, it catches
20150 size_t overflow on (unusual) hosts where SIZE_MAX <= min
20151 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
20152 and ptrdiff_t and EMACS_INT are both 64 bits.
20154 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
20155 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
20156 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
20158 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
20160 * alloc.c (Fmake_string): Check for out-of-range init.
20162 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
20164 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
20166 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
20168 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
20169 xg_get_default_scrollbar_width.
20171 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
20172 (int_gtk_range_get_value): Move to the scroll bar part of the file.
20173 (style_changed_cb): Call update_theme_scrollbar_width and call

20175 all frames (Bug#8505).
20176 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).

20179 and height if HAVE_GTK3 (Bug#8505).
20180 (scroll_bar_width_for_theme): New variable.
20181 (update_theme_scrollbar_width): New function.
20182 (xg_get_default_scrollbar_width): Move code to
20183 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
20184 (xg_initialize): Call update_theme_scrollbar_width.
20186 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
20188 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
20190 2011-06-12 Martin Rudalics <rudalics@gmx.at>
20192 * frame.c (make_frame): Call other_buffer_safely instead of
20195 * window.c (temp_output_buffer_show): Call display_buffer with
20196 second argument Vtemp_buffer_show_specifiers and reset latter
20197 immediately after the call.
20198 (Vtemp_buffer_show_specifiers): New variable.
20199 (auto_window_vscroll_p, next_screen_context_lines)
20200 (Vscroll_preserve_screen_position): Remove leading asterisks from

20246 (Fset_window_configuration): Rewrite to handle dead buffers and
20247 consequently deletable windows.
20248 (window_tree, Fwindow_tree): Remove. Supply functionality in

20383 Remove static from declaration of Qdelete_window, it's
20384 temporarily needed by Fbury_buffer.
20385 (replace_window): Don't assign orig_top_line and

20389 (window_loop): Remove DELETE_OTHER_WINDOWS case.
20390 Replace Fdelete_window calls with calls to Qdelete_window.
20391 (Fdelete_other_windows): Remove. Deleting other windows is

20797 Without this change, the gnutls library would invoke malloc etc.
20798 directly, which causes problems on non-SYNC_INPUT hosts, and which
20799 runs afoul of improving memory_full behavior. (Bug#8761)
20800 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20801 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,

20803 (Fgnutls_boot): No need to check for memory allocation failure,
20804 since xmalloc does that for us.

20833 need to be updated by these changes.
20834 * fns.c (make_hash_table, maybe_resize_hash_table):
20835 Check for integer overflow with large hash tables.
20836 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20837 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20838 (SXHASH_REDUCE): New macro.

20842 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20843 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20844 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20845 Rewrite to use FIXNUM_BITS, as this simplifies things.
20846 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20847 Adjust signatures to match updated version of code.
20848 (consing_since_gc): Now EMACS_INT, since a single hash table can
20849 use more than INT_MAX bytes.
20851 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
20853 Make it possible to build with GCC-4.6+ -O2 -flto.
20855 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
20857 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
20859 * minibuf.c (get_minibuffer, read_minibuf_unwind):
20860 Call minibuffer-inactive-mode.
20862 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
20864 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
20865 Update dependencies.
20867 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20869 * data.c (init_data): Remove code for UTS, this system is not
20872 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20874 Don't force ./temacs to start in terminal mode.
20876 * frame.c (make_initial_frame): Initialize faces in all cases, not
20877 only when CANNOT_DUMP is defined.
20878 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
20880 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20882 * dispnew.c (add_window_display_history): Use const for the string
20883 pointer. Remove declaration, not needed.
20885 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20887 Use 'inline', not 'INLINE'.
20888 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20889 * alloc.c, fontset.c (INLINE): Remove.
20890 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20891 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20892 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20893 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20894 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20896 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20898 Make it possible to run ./temacs.
20900 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20901 syms_of_callproc does the same thing. Remove test for
20902 "initialized", do it in the caller.
20903 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20905 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20907 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20908 (read_minibuf): Use get_minibuffer.
20909 (syms_of_minibuf): Use DEFSYM.
20910 (Qmetadata): New var.
20911 * data.c (Qbuffer): Don't make it static.
20912 (syms_of_data): Use DEFSYM.
20914 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20916 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20917 (CCL_CODE_MIN): New macro.
20919 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20921 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20923 * eval.c (Qdebug): Now static.
20924 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20925 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20926 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20928 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20930 * image.c: Various fixes to ImageMagick code comments.
20931 (Fimagemagick_types): Doc fix.
20933 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20935 Minor fixes prompted by GCC 4.6.0 warnings.
20937 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20939 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20940 (x_clipboard_manager_save_all): Move extern decl to ...
20941 * xterm.h: ... here, so that it can be checked for consistency.
20943 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20945 * xselect.c (x_clipboard_manager_save_frame)
20946 (x_clipboard_manager_save_all): New functions.
20947 (Fx_clipboard_manager_save): Lisp function deleted.
20949 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20950 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20952 * xterm.h: Update prototype.
20954 2011-05-28 William Xu <william.xwl@gmail.com>
20956 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20957 exiting (Bug#8239).
20959 2011-05-28 Jim Meyering <meyering@redhat.com>
20961 Avoid a sign-extension bug in crypto_hash_function.
20962 * fns.c (to_uchar): Define.
20963 (crypto_hash_function): Use it to convert some newly-signed
20964 variables to unsigned, to avoid sign-extension bugs. For example,
20965 without this change, (md5 "truc") would evaluate to
20966 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20967 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20968 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20970 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20972 Integer overflow fixes.
20974 * dbusbind.c: Serial number integer overflow fixes.
20975 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20976 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20977 to hold a serial number that is too large for a fixnum.
20978 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20979 Check for serial numbers out of range. Decode any serial number
20980 that was so large that it became a float. (Bug#8722)
20982 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20983 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20984 Use XFASTINT rather than XUINT when numbers are nonnegative.
20985 (xd_append_arg, Fdbus_method_return_internal):
20986 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20987 arguments, check that Lisp number is nonnegative, rather than
20988 silently wrapping negative numbers around. (Bug#8722)
20989 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20992 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20994 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20996 ccl: Add integer overflow checks.
20997 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20998 (IN_INT_RANGE): New macros.
20999 (ccl_driver): Use them to check for integer overflow when
21000 decoding a CCL program. Many of the new checks are whether XINT (x)
21001 fits in int; it doesn't always, on 64-bit hosts. The new version
21002 doesn't catch all possible integer overflows, but it's an
21003 improvement. (Bug#8719)
21005 * alloc.c (make_event_array): Use XINT, not XUINT.
21006 There's no need for unsigned here.
21008 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
21009 This follows up to the 2011-05-06 change that substituted uintptr_t
21010 for EMACS_INT. This case wasn't caught back then.
21012 Rework Fformat to avoid integer overflow issues.
21013 * editfns.c: Include <float.h> unconditionally, as it's everywhere
21014 now (part of C89). Include <verify.h>.
21015 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
21016 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
21017 (Fformat): Avoid the prepass trying to compute sizes; it was only
21018 approximate and thus did not catch overflow reliably. Instead, walk
21019 through the format just once, formatting and computing sizes as we go,
21020 checking for integer overflow at every step, and allocating a larger
21021 buffer as needed. Keep track separately whether the format is
21022 multibyte. Keep only the most-recently calculated precision, rather
21023 than them all. Record whether each argument has been converted to
21024 string. Use EMACS_INT, not int, for byte and char and arg counts.
21025 Support field widths and precisions larger than INT_MAX. Avoid
21026 sprintf's undefined behavior with conversion specifications such as %#d
21027 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
21028 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
21029 formatting out-of-range floating point numbers with int
21030 formats. (Bug#8668)
21032 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
21034 * data.c: Avoid integer truncation in expressions involving floats.
21035 * data.c: Include <intprops.h>.
21036 (arith_driver): When there's an integer overflow in an expression
21037 involving floating point, convert the integers to floating point
21038 so that the resulting value does not suffer from catastrophic
21039 integer truncation. For example, on a 64-bit host (* 4
21040 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
21041 Do not rely on undefined behavior after integer overflow.
21043 merge count_size_as_multibyte, parse_str_to_multibyte
21044 * character.c, character.h (count_size_as_multibyte):
21045 Rename from parse_str_to_multibyte; all uses changed.
21046 Check for integer overflow.
21047 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
21048 since it's now a duplicate of the other. This is more of
21049 a character than a buffer op, so better that it's in character.c.
21050 * fns.c, print.c: Adjust to above changes.
21052 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
21054 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
21056 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
21058 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
21059 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
21060 (x_clipboard_manager_save): Now static.
21061 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
21063 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
21064 (crypto_hash_function): Now static.
21065 Fix pointer signedness problems. Avoid unnecessary initializations.
21067 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
21069 * termhooks.h (Vselection_alist): Make it terminal-local.
21071 * terminal.c (create_terminal): Initialize it.
21073 * xselect.c: Support for clipboard managers.
21074 (Vselection_alist): Move to termhooks.h as terminal-local var.
21075 (LOCAL_SELECTION): New macro.
21076 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
21077 (symbol_to_x_atom): Remove gratuitous arg.
21078 (x_handle_selection_request, lisp_data_to_selection_data)
21079 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
21080 (x_own_selection, x_get_local_selection, x_convert_selection):
21081 New arg, specifying work frame. Use terminal-local Vselection_alist.
21082 (some_frame_on_display): Delete unused function.
21083 (Fx_own_selection_internal, Fx_get_selection_internal)
21084 (Fx_disown_selection_internal, Fx_selection_owner_p)
21085 (Fx_selection_exists_p): New optional frame arg.
21086 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
21087 (x_handle_selection_clear): Don't treat other terminals with the
21088 same keyboard specially. Use the terminal-local Vselection_alist.
21089 (x_clear_frame_selections): Use Frun_hook_with_args.
21091 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
21093 * xterm.h: Add support for those atoms.
21095 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
21097 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
21098 (converted_selections, conversion_fail_tag): New global variables.
21099 (x_selection_request_lisp_error): Free the above.
21100 (x_get_local_selection): Remove unnecessary code.
21101 (x_reply_selection_request): Args changed; handle arbitrary array
21102 of converted selections stored in converted_selections.
21103 Separate the XChangeProperty and SelectionNotify steps.
21104 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
21105 (x_convert_selection): New function.
21106 (x_handle_selection_event): Simplify.
21107 (x_get_foreign_selection): Don't ignore incoming requests while
21108 waiting for an answer; this will fail when we implement
21109 SAVE_TARGETS, and seems unnecessary anyway.
21110 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
21111 (Vx_sent_selection_functions): Doc fix.
21113 2011-05-26 Leo Liu <sdl.web@gmail.com>
21115 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
21117 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21119 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
21121 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
21122 for fringe update if it has periodic bitmap.
21123 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
21124 and fringe_bitmap_periodic_p.
21126 * fringe.c (get_fringe_bitmap_data): New function.
21127 (draw_fringe_bitmap_1, update_window_fringes): Use it.
21128 (update_window_fringes): Record periodicity of fringe bitmap in glyph
21129 row. Mark glyph row for fringe update if periodicity changed.
21131 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
21132 for fringe update unless it has periodic bitmap.
21134 2011-05-25 Kenichi Handa <handa@m17n.org>
21136 * xdisp.c (get_next_display_element): Set correct it->face_id for
21137 a static composition.
21139 2011-05-24 Leo Liu <sdl.web@gmail.com>
21142 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
21144 * fns.c (crypto_hash_function, Fsha1): New function.
21145 (Fmd5): Use crypto_hash_function.
21146 (syms_of_fns): Add Ssha1.
21148 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
21150 * gnutls.c: Remove unused macros.
21151 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
21152 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
21153 Remove macros that are defined and never used.
21154 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
21156 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
21158 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
21159 (Fx_get_selection_internal): Minor cleanup.
21160 (Fx_own_selection_internal): Rename arguments for consistency with
21163 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
21165 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
21167 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
21169 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
21171 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21173 * dispnew.c (scrolling_window): Don't exclude the case that the
21174 last enabled row in the desired matrix touches the bottom boundary.
21176 2011-05-21 Glenn Morris <rgm@gnu.org>
21178 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
21179 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
21180 and add some more files.
21182 2011-05-20 Eli Zaretskii <eliz@gnu.org>
21184 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
21185 report_file_error introduced by the change from 2011-05-07.
21187 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
21189 * systime.h (Time): Define only if emacs is defined.
21190 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
21191 where the include path doesn't have X11/X.h by default. See
21192 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
21194 2011-05-20 Kenichi Handa <handa@m17n.org>
21196 * composite.c (find_automatic_composition): Fix previous change.
21198 2011-05-20 Glenn Morris <rgm@gnu.org>
21200 * lisp.mk: New file, split from Makefile.in.
21201 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
21202 (shortlisp): Remove.
21203 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
21205 2011-05-19 Glenn Morris <rgm@gnu.org>
21207 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
21208 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
21209 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
21210 (lisp): Set the order to that of loadup.el.
21211 (shortlisp): Make it a copy of $lisp.
21212 (SOME_MACHINE_LISP): Remove.
21213 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
21214 Use just $shortlisp, not $SOME_MACHINE_LISP too.
21216 2011-05-18 Kenichi Handa <handa@m17n.org>
21218 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
21219 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
21220 (find_automatic_composition): Mostly rewrite for efficiency.
21222 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
21224 * makefile.w32-in: Update dependencies.
21226 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
21228 * menu.c: Include limits.h (fixes the MS-Windows build broken by
21229 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
21231 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
21233 Fix some integer overflow issues, such as string length overflow.
21235 * insdel.c (count_size_as_multibyte): Check for string overflow.
21237 * character.c (lisp_string_width): Check for string overflow.
21238 Use EMACS_INT, not int, for string indexes and lengths; in
21239 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
21240 the resulting string length overflows an EMACS_INT; instead,
21241 report a string overflow if no precision given. When checking for
21242 precision exhaustion, use a check that cannot possibly have
21243 integer overflow. (Bug#8675)
21244 * character.h (lisp_string_width): Adjust to new signature.
21246 * alloc.c (string_overflow): New function.
21247 (Fmake_string): Use it. This doesn't change behavior, but saves
21248 a few bytes and will simplify future changes.
21249 * character.c (string_escape_byte8): Likewise.
21250 * lisp.h (string_overflow): New decl.
21252 Fixups, following up to the user-interface timestamp change.
21253 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
21254 for UI timestamps, instead of unsigned long.
21255 * msdos.c (mouse_get_pos): Likewise.
21256 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
21257 * w32gui.h (Time): Define by including "systime.h" rather than by
21258 declaring it ourselves. (Bug#8664)
21260 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
21261 * image.c (clear_image_cache): Likewise.
21263 * term.c (term_mouse_position): Don't assume time_t wraparound.
21265 Be more systematic about user-interface timestamps.
21266 Before, the code sometimes used 'Time', sometimes 'unsigned long',
21267 and sometimes 'EMACS_UINT', to represent these timestamps.
21268 This change causes it to use 'Time' uniformly, as that's what X uses.
21269 This makes the code easier to follow, and makes it easier to catch
21270 integer overflow bugs such as Bug#8664.
21271 * frame.c (Fmouse_position, Fmouse_pixel_position):
21272 Use Time, not unsigned long, for user-interface timestamps.
21273 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
21274 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
21275 * keyboard.h (last_event_timestamp): Likewise.
21276 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
21277 * menu.h (xmenu_show): Likewise.
21278 * term.c (term_mouse_position): Likewise.
21279 * termhooks.h (struct input_event.timestamp): Likewise.
21280 (struct terminal.mouse_position_hook): Likewise.
21281 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
21282 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
21283 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
21284 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
21285 what it was before.
21286 * menu.h, termhooks.h: Include "systime.h", for Time.
21288 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
21289 Don't assume that the difference between two unsigned long values
21290 can fit into an integer. At this point, we know button_down_time
21291 <= event->timestamp, so the difference must be nonnegative, so
21292 there's no need to cast the result if double-click-time is
21293 nonnegative, as it should be; check that it's nonnegative, just in
21294 case. This bug is triggered when events are more than 2**31 ms
21295 apart (about 25 days). (Bug#8664)
21297 * xselect.c (last_event_timestamp): Remove duplicate decl.
21298 (x_own_selection): Remove needless cast to unsigned long.
21300 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
21301 that always fit in int. Use a sentinel instead of a counter, to
21302 avoid a temp and to allay GCC's concerns about possible int overflow.
21303 * frame.h (struct frame): Use int for menu_bar_items_used
21304 instead of EMACS_INT, since it always fits in int.
21306 * menu.c (grow_menu_items): Check for int overflow.
21308 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
21310 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
21311 Before, the code was not consistent. These values cannot exceed
21312 2**31 - 1 so there's no need to make them unsigned.
21313 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
21314 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
21315 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
21317 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
21319 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
21320 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
21321 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
21322 presumably because the widths might not match.
21324 * window.c (size_window): Avoid needless test at loop start.
21326 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
21328 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
21330 2011-05-12 Drew Adams <drew.adams@oracle.com>
21332 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
21334 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21336 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
21337 `width' to `bar_area_x' and `bar_area_width', respectively.
21338 (x_scroll_run): Take account of fringe background extension.
21340 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
21341 Rename local vars `left' and `width' to `bar_area_x' and
21342 `bar_area_width', respectively.
21343 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
21344 background extension.
21346 2011-05-10 Jim Meyering <meyering@redhat.com>
21348 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
21350 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
21352 * image.c (Finit_image_library): Return t for built-in image types,
21353 like pbm and xbm. (Bug#8640)
21355 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
21357 * w32menu.c (set_frame_menubar): Fix submenu allocation.
21359 2011-05-07 Eli Zaretskii <eliz@gnu.org>
21361 * w32console.c (Fset_screen_color): Doc fix.
21362 (Fget_screen_color): New function.
21363 (syms_of_ntterm): Defsubr it.
21365 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
21366 unlink the temporary file if Fcall_process didn't create it in the
21368 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
21369 child process will be redirected to a file specified with `:file'.
21370 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
21371 cue to call_process_cleanup not to close that handle.
21373 2011-05-07 Ben Key <bkey76@gmail.com>
21375 * makefile.w32-in: The bootstrap-temacs rule now makes use of
21376 one of two shell specific rules, either bootstrap-temacs-CMD or
21377 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
21378 to the previous implementation of the bootstrap-temacs rule.
21379 The bootstrap-temacs-CMD rule is similar to the previous
21380 implementation of the bootstrap-temacs rule except that it
21381 makes use of the ESC_CFLAGS variable instead of the CFLAGS
21384 These changes, along with some changes to nt/configure.bat,
21385 nt/gmake.defs, and nt/nmake.defs, are required to extend my
21386 earlier fix to add support for --cflags and --ldflags options
21387 that include quotes so that it works whether make uses cmd or
21390 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
21392 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
21393 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
21395 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
21396 a string. Handle both cases.
21397 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
21398 (Fdbus_register_method): Use Qinvalid_function.
21400 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21402 * makefile.w32-in: Update dependencies.
21403 (LISP_H): Add inttypes.h and stdin.h.
21404 (PROCESS_H): Add unistd.h.
21406 2011-05-06 Eli Zaretskii <eliz@gnu.org>
21408 * lread.c: Include limits.h (fixes the MS-Windows build broken by
21409 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
21411 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
21413 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
21415 * term.c (vfatal): Remove stray call to va_end.
21416 It's not needed and the C Standard doesn't allow it here anyway.
21418 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
21419 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
21421 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
21424 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
21426 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
21428 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
21430 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
21432 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
21434 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
21435 * charset.c (Fdefine_charset_internal): Don't initialize
21436 charset.code_space[15]. The value was garbage, on hosts with
21437 32-bit int (Bug#8600).
21439 * lread.c (read_integer): Be more consistent with string-to-number.
21440 Use string_to_number to do the actual conversion; this avoids
21441 rounding errors and fixes some other screwups. Without this fix,
21442 for example, #x1fffffffffffffff was misread as -2305843009213693952.
21443 (digit_to_number): Move earlier, for benefit of read_integer.
21444 Return -1 if the digit is out of range for the base, -2 if it is
21445 not a digit in any supported base. (Bug#8602)
21447 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
21449 * dispnew.c (scrolling_window): Return 1 if we scrolled,
21450 to match comment at start of function. This also removes a
21451 GCC warning about overflow in a 32+64-bit port.
21453 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
21455 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
21456 Reported by Stefan Monnier in
21457 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
21458 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21459 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
21461 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
21462 (EMACS_UINTPTR): Likewise, with uintptr_t.
21464 * lisp.h: Prefer 64-bit EMACS_INT if available.
21465 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
21466 on 32-bit hosts that have 64-bit int, so that they can access
21468 However, temporarily disable this change unless the temporary
21469 symbol WIDE_EMACS_INT is defined.
21471 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
21473 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
21474 This removes an assumption that EMACS_INT and long are the same
21475 width as pointers. The assumption is true for Emacs porting targets
21476 now, but we want to make other targets possible.
21477 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
21478 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
21479 In the rest of the code, change types of integers that hold casted
21480 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
21481 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
21482 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
21483 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
21484 No need to cast type when ORing.
21485 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
21486 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
21487 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
21488 assume EMACS_INT is the same width as char *.
21489 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
21490 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
21491 Remove no-longer-needed casts.
21492 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
21493 (xg_tool_bar_help_callback, xg_make_tool_item):
21494 Use EMACS_INTPTR to hold an integer
21495 that will be cast to void *; this can avoid a GCC warning
21496 if EMACS_INT is not the same width as void *.
21497 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
21498 * xdisp.c (display_echo_area_1, resize_mini_window_1):
21499 (current_message_1, set_message_1):
21500 Use a local to convert to proper width without a cast.
21501 * xmenu.c (dialog_selection_callback): Likewise.
21503 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
21504 Also, don't assume VALBITS / RAND_BITS is less than 5,
21505 and don't rely on undefined behavior when shifting a 1 left into
21507 * lisp.h (get_random): Change signature to match.
21509 * lread.c (hash_string): Use size_t, not int, for hash computation.
21510 Normally we prefer signed values; but hashing is special, because
21511 it's better to use unsigned division on hash table sizes so that
21512 the remainder is nonnegative. Also, size_t is the natural width
21513 for hashing into memory. The previous code used 'int', which doesn't
21514 retain enough info to hash well into very large tables.
21515 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
21517 * dbusbind.c: Don't possibly lose pointer info when converting.
21518 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21519 Use XPNTR rather than XHASH, so that the high-order bits of
21520 the pointer aren't lost when converting through void *.
21522 * eval.c (Fautoload): Don't double-shift a pointer.
21524 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
21526 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21528 * gnutls.c (DEF_GNUTLS_FN):
21529 * image.c (DEF_IMGLIB_FN): Make function pointers static.
21531 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
21533 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
21536 2011-05-05 Eli Zaretskii <eliz@gnu.org>
21538 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
21539 New version that can reserve upto 2GB of heap space.
21541 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
21543 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
21545 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
21547 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
21548 `gnutls_certificate_set_x509_key_file'.
21550 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
21552 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
21553 Update dependencies.
21555 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21557 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
21558 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
21559 Remove unused parameter `fildes'.
21560 * process.c (read_process_output, send_process): Don't pass it.
21562 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21564 Fix previous change: the library cache is defined in w32.c.
21565 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
21566 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
21568 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21570 Implement dynamic loading of GnuTLS on Windows.
21572 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
21573 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
21574 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21577 * gnutls.c (Qgnutls_dll): Define.
21578 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
21579 (gnutls_*): Declare function pointers.
21580 (init_gnutls_functions): New function to initialize function pointers.
21581 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
21582 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
21583 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21584 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
21585 (emacs_gnutls_write, emacs_gnutls_read)
21586 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
21587 (Fgnutls_available_p): New function.
21588 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
21589 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
21590 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
21592 * image.c: Include w32.h.
21593 (Vimage_type_cache): Delete.
21594 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
21595 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
21596 (w32_delayed_load): Move to w32.c.
21598 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
21600 * w32.c (QCloaded_from, Vlibrary_cache): Define.
21601 (w32_delayed_load): Move from image.c. When loading a library, record
21602 its filename in the :loaded-from property of the library id.
21603 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
21604 Initialize and staticpro them.
21605 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
21607 * process.c: Include lisp.h before w32.h, not after.
21608 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
21609 instead of gnutls_record_check_pending.
21611 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
21613 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
21615 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
21616 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
21619 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
21621 * xterm.c (x_set_frame_alpha): Do not set property on anything
21622 else than FRAME_X_OUTER_WINDOW (Bug#8608).
21624 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21626 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
21628 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21630 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
21631 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

21637 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
21638 (Qgnutls_bootprop_callbacks_verify): Make static.
21640 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
21642 * callproc.c: Indentation fixup.
21644 * sysdep.c (wait_for_termination_1): Make static.
21645 (wait_for_termination, interruptible_wait_for_termination):
21646 Move after wait_for_termination_1.
21648 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
21650 * sysdep.c (interruptible_wait_for_termination): New function
21651 which is like wait_for_termination, but allows keyboard
21654 * callproc.c (Fcall_process): Add (:file "file") as an option for
21656 (Fcall_process_region): Ditto.
21658 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21660 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21661 rather than `XVECTOR (FOO)->size'.
21663 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21664 inttypes.h, as a gnulib replacement is used if it not available in
21667 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21669 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21670 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21671 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21673 * coding.c (coding_alloc_by_realloc): Error out if destination
21674 will grow beyond MOST_POSITIVE_FIXNUM.
21675 (decode_coding_emacs_mule): Abort if there isn't enough place in
21676 charbuf for the composition carryover bytes. Reserve an extra
21677 space for up to 2 characters produced in a loop.
21678 (decode_coding_iso_2022): Abort if there isn't enough place in
21679 charbuf for the composition carryover bytes.
21681 2011-04-21 Eli Zaretskii <eliz@gnu.org>

21684 aborting when %lld or %lll format is passed.
21685 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21686 %llo or %llx format is passed. (Bug#8545)
21688 * window.c (window_scroll_line_based): Use a marker instead of
21689 simple variables to record original value of point. (Bug#7952)
21691 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21692 produced by %s or %c overflows available buffer space. (Bug#8545)
21694 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21696 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21697 (SIZE_MAX): Move defn after all includes, as they might #define it.
21699 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21701 * w32.c (init_environment): Warn about defaulting HOME to C:\.
21703 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

21707 if Vdelayed_warnings_list is non-nil.
21708 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
21709 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
21711 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21713 * doprnt.c (doprnt): Don't return value smaller than the buffer
21714 size if the message was truncated. (Bug#8545).
21716 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21718 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
21719 (Fx_window_property): #if-0 the whole functions, not just the bodies.
21721 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21723 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21725 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21727 * makefile.w32-in: Update dependencies.
21729 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21731 Improve `doprnt' and its usage. (Bug#8545)
21732 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21733 `format_end'. Remove support for %l as a conversion specifier.
21734 Don't use xrealloc. Improve diagnostics when the %l size modifier
21735 is used. Update the commentary.
21737 * eval.c (verror): Simplify calculation of size_t.
21739 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21742 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21744 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21747 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21749 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21750 This makes this file independent of the recent pseudovector change.
21752 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21754 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21756 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21757 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21758 Remove unused local.
21759 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21761 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21762 GCC 4.6.0 optimizes based on type-based alias analysis.
21763 For example, if b is of type struct buffer * and v of type struct
21764 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21765 != &v->size, and therefore "v->size = 1; b->size = 2; return
21766 v->size;" must therefore return 1. This assumption is incorrect
21767 for Emacs, since it type-puns struct Lisp_Vector * with many other
21768 types. To fix this problem, this patch adds a new type struct
21769 vectorlike_header that documents the constraints on layout of vectors
21770 and pseudovectors, and helps optimizing compilers not get fooled
21771 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21772 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21773 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21775 (XSETPVECTYPE): Rewrite in terms of new macro.
21776 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21777 This is a bit clearer, and further avoids the possibility of
21778 undesirable aliasing.
21779 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21780 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21781 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21782 since Lisp_Subr is a special case (no "next" field).
21783 (ASIZE): Now uses header.size rather than size.
21784 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21785 to avoid the hassle of writing XVECTOR (foo)->header.size.
21786 (struct vectorlike_header): New type.
21787 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21788 object, to help avoid aliasing.
21789 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21790 (SUBRP): Likewise, since Lisp_Subr is a special case.
21791 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21792 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21793 (struct Lisp_Hash_Table): Combine first two members into a single
21794 struct vectorlike_header member. All uses of "size" and "next" members
21795 changed to be "header.size" and "header.next".
21796 * buffer.h (struct buffer): Likewise.
21797 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21798 * frame.h (struct frame): Likewise.
21799 * process.h (struct Lisp_Process): Likewise.
21800 * termhooks.h (struct terminal): Likewise.
21801 * window.c (struct save_window_data, struct saved_window): Likewise.
21802 * window.h (struct window): Likewise.
21803 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21804 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21805 * buffer.c (init_buffer_once): Likewise.
21806 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21808 * process.c (Fformat_network_address): Use local var for size,
21811 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21813 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21814 * data.c (atof): Remove decl; no longer used or needed.
21815 (digit_to_number): Move to lread.c.
21816 (Fstring_to_number): Use new string_to_number function, to be
21817 consistent with how the Lisp reader treats infinities and NaNs.
21818 Do not assume that floating-point numbers represent EMACS_INT
21819 without losing information; this is not true on most 64-bit hosts.
21820 Avoid double-rounding errors, by insisting on integers when
21821 parsing non-base-10 numbers, as the documentation specifies.
21822 * lisp.h (string_to_number): New decl, replacing ...
21823 (isfloat_string): Remove.
21824 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21825 (read1): Do not accept +. and -. as integers; this
21826 appears to have been a coding error. Similarly, do not accept
21827 strings like +-1e0 as floating point numbers. Do not report
21828 overflow for integer overflows unless the base is not 10 which
21829 means we have no simple and reliable way to continue.
21830 Break out the floating-point parsing into a new
21831 function string_to_number, so that Fstring_to_number parses
21832 floating point numbers consistently with the Lisp reader.
21833 (digit_to_number): Move here from data.c. Make it static inline.
21834 (E_CHAR, EXP_INT): Remove, replacing with ...
21835 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21836 (string_to_number): New function, replacing isfloat_string.
21837 This function checks for valid syntax and produces the resulting
21838 Lisp float number too. Rework it so that string-to-number
21839 no longer mishandles examples like "1.0e+". Use strtoumax,
21840 so that overflow for non-base-10 numbers is reported only when
21841 there's no portable and simple way to convert to floating point.
21843 * textprop.c (set_text_properties_1): Rewrite for clarity,
21844 and to avoid GCC warning about integer overflow.
21846 * intervals.h (struct interval): Use EMACS_INT for members
21847 where EMACS_UINT might cause problems. See
21848 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21849 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21850 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21852 (offset_intervals): Tell GCC not to worry about length overflow
21853 when negating a negative length.
21855 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21856 (overrun_check_free): Likewise.
21858 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21859 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21862 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21863 (gnutls_make_error): Rename local to avoid shadowing.
21864 (gnutls_emacs_global_deinit): ifdef out; not used.
21865 (Fgnutls_boot): Use const for pointer to readonly storage.
21866 Comment out unused local. Fix pointer signedness problems.
21868 * lread.c (openp): Don't stuff size_t into an 'int'.
21869 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21870 about possible signed overflow.
21872 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21873 (GDK_KEY_g): Don't define if already defined.
21874 (xg_prepare_tooltip): Avoid pointer signedness problem.
21875 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21877 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21878 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21880 * xfns.c (Fx_window_property): Simplify a bit,
21881 to make a bit faster and to avoid GCC 4.6.0 warning.
21882 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21884 * fns.c (internal_equal): Don't assume size_t fits in int.
21886 * alloc.c (compact_small_strings): Tighten assertion a little.
21888 Replace pEd with more-general pI, and fix some printf arg casts.
21889 * lisp.h (pI): New macro, generalizing old pEd macro to other
21890 conversion specifiers. For example, use "...%"pI"d..." rather
21891 than "...%"pEd"...".
21892 (pEd): Remove. All uses replaced with similar uses of pI.
21893 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21894 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21895 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21896 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21897 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21898 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21899 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21901 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21902 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21903 * print.c (safe_debug_print, print_object): Likewise.
21904 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21906 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21907 avoiding the 0 flag, which is not portable.
21908 * process.c (Fmake_network_process): Use pI to avoid cast.
21909 * region-cache.c (pp_cache): Likewise.
21910 * xdisp.c (decode_mode_spec): Likewise.
21911 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21912 behavior on 64-bit hosts with printf arg.
21913 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21914 (x_stop_queuing_selection_requests): Likewise.
21915 (x_get_window_property): Don't truncate byte count to an 'int'
21918 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21919 here, since it parses constructs like leading '-' and spaces,
21920 which are not wanted; and it overflows with large numbers.
21921 Instead, simply match F[0-9]+, which is what is wanted anyway.
21923 * alloc.c: Remove unportable assumptions about struct layout.
21924 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21925 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21926 (allocate_vectorlike, make_pure_vector): Use the new macros,
21927 plus offsetof, to remove unportable assumptions about struct layout.
21928 These assumptions hold on all porting targets that I know of, but
21929 they are not guaranteed, they're easy to remove, and removing them
21930 makes further changes easier.
21932 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21933 This doesn't fix a bug but makes the code clearer.
21934 (string_overrun_cookie): Now const. Use initializers that
21935 don't formally overflow signed char, to avoid warnings.
21936 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21937 can cause Emacs to crash when string overrun checking is enabled.
21938 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21939 multiple of sizeof (EMACS_INT); it need not be, if
21940 alignof(EMACS_INT) < sizeof (EMACS_INT).
21941 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21943 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

21947 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
21949 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
21950 supposed to be handshaking. (Bug#8556)
21951 Reported by Paul Eggert <eggert@cs.ucla.edu>.
21953 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
21955 * lisp.h (Qdebug): List symbol.
21956 * eval.c (Qdebug): Restore global linkage.

21958 (handle_user_signal): Break into debugger when debug-on-event
21959 matches the current signal symbol.
21961 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
21963 * alloc.c (check_sblock, check_string_bytes)
21964 (check_string_free_list): Convert to standard C.
21966 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
21968 * w32.c (emacs_gnutls_push): Fix typo.
21970 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21972 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21973 "cast to pointer from integer of different size".
21975 Improve doprnt and its use in verror. (Bug#8545)
21976 * doprnt.c (doprnt): Document the set of format control sequences
21977 supported by the function. Use SAFE_ALLOCA instead of always
21980 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21981 is one byte too soon. Don't use xrealloc; instead xfree and
21984 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21986 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21989 * gnutls.c: Renamed global_initialized to
21990 gnutls_global_initialized. Added internals for the
21991 :verify-hostname-error, :verify-error, and :verify-flags
21992 parameters of `gnutls-boot' and documented those parameters in the
21993 docstring. Start callback support.
21994 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21995 unless a fatal error occurred. Call gnutls_alert_send_appropriate
21996 on error. Return error code.
21997 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
21998 (emacs_gnutls_read): Likewise.
21999 (Fgnutls_boot): Return handshake error code.
22000 (emacs_gnutls_handle_error): New function.
22001 (wsaerror_to_errno): Likewise.

22012 buffered some data internally if no FDs are set for TLS
22015 * makefile.w32-in (OBJ2): Add gnutls.$(O).

22063 <char-direction-table>: Deleted.
22065 2011-04-23 Eli Zaretskii <eliz@gnu.org>
22067 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
22068 * doprnt.c: Include limits.h.
22069 (SIZE_MAX): New macro.
22070 (doprnt): Return a size_t value. 2nd arg is now size_t.
22071 Many local variables are now size_t instead of int or unsigned.
22072 Improve overflow protection. Support `l' modifier for integer
22073 conversions. Support %l conversion. Don't assume an EMACS_INT
22074 argument for integer conversions and for %c.
22076 * lisp.h (doprnt): Restore prototype.
22078 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
22079 $(SRC)/character.h.
22081 * Makefile.in (base_obj): Add back doprnt.o.
22083 * deps.mk (doprnt.o): Add back prerequisites.
22084 (callint.o): Depend on character.h.
22086 * eval.c (internal_lisp_condition_case): Include the handler
22087 representation in the error message.
22088 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
22089 when breaking from the loop.
22091 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
22093 * callint.c (Fcall_interactively): When displaying error message
22094 about invalid control letter, pass the character's codepoint, not
22095 a pointer to its multibyte form. Improve display of the character
22096 in octal and display also its hex code.
22098 * character.c (char_string): Use %x to display the (unsigned)
22099 codepoint of an invalid character, to avoid displaying a bogus
22102 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
22103 `error', not SYMBOL_NAME itself.
22105 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
22106 character arguments to `error'.
22108 * charset.c (check_iso_charset_parameter): Fix incorrect argument
22109 to `error' in error message about FINAL_CHAR argument. Make sure
22110 FINAL_CHAR is a character, and use %c when it is passed as
22111 argument to `error'.

22175 Define only if needed.
22177 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
22178 by pacifying GCC about it. Maybe it's time to retire it?
22179 * xfaces.c (USG, __TIMEVAL__): Likewise.
22181 * dispextern.h (struct redisplay_interface): Rename param
22182 to avoid shadowing.

22230 compatible char. Avoid the old compiler warnings about
22231 out-of-range initializers by using, for example, '\xab' rather
22234 * xgselect.c (xgselect_initialize): Check vs interface
22235 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

22300 * nsfont.m: Fixed bugs in ns_get_family and
22301 ns_descriptor_to_entity that were caused by using free to
22302 deallocate memory blocks that were allocated by xmalloc (via
22303 xstrdup). This caused Emacs to crash when compiled with
22304 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
22305 --enable-checking=xmallocoverrun). xfree is now used to
22306 deallocate these memory blocks.

22320 (emacs_read, emacs_write): Remove check for negative size, as the
22321 Emacs source code has been audited now.
22322 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
22323 (emacs_read, emacs_write): Use it.
22324 * process.c (send_process): Adjust to the new signatures of
22325 emacs_write and emacs_gnutls_write. Do not attempt to store
22326 a byte offset into an 'int'; it might overflow.
22327 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

22661 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
22662 * dispextern.h (bidi_dump_cached_states): Remove, since it's
22663 exported only to the debugger.
22665 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
22666 * atimer.h (run_all_atimers): Remove; not exported.
22668 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
22669 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
22670 was inaccessible from Lisp.
22671 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
22672 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
22674 alloc.c: Import and export fewer symbols, and remove unused items.
22675 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
22677 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
22678 it's not optimized away by whole-program optimization.

22691 (mark_backtrace): Define only if BYTE_MARK_STACK.
22692 * xdisp.c (message_enable_multibyte): Now static.
22694 Declare Lisp_Object Q* variables to be 'static' if not exported.
22695 This makes it easier for human readers (and static analyzers)
22696 to see whether these variables are used from other modules.
22697 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

22708 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
22710 * lisp.h (DEFINE_FUNC): Make sname 'static'.
22712 Make Emacs functions such as Fatom 'static' by default.
22713 This makes it easier for human readers (and static analyzers)
22714 to see whether these functions can be called from other modules.
22715 DEFUN now defines a static function. To make the function external
22716 so that it can be used in other C modules, use the new macro DEFUE.

22722 Remove decls, since these functions are now static.
22723 (Funintern, Fget_internal_run_time): New decls, since these functions
22724 were already external.

22737 decls for now-static functions.

22774 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22776 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22777 when at ZV. (Bug#8487)
22779 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>

22789 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22790 (overrun_check_free): Protoize.
22792 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22794 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22795 since callers should never pass a negative size.
22796 Change the signature to match that of plain 'read' and 'write'; see
22797 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22798 * lisp.h: Update prototypes of emacs_write and emacs_read.
22800 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22802 * xdisp.c (redisplay_window): Don't try to determine the character
22803 position of the scroll margin if the window start point w->startp
22804 is outside the buffer's accessible region. (Bug#8468)
22806 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22808 Fix write-region and its subroutines for buffers > 2GB.
22809 * fileio.c (a_write, e_write): Modify declaration of arguments and
22810 local variables to support buffers larger than 2GB.
22811 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22813 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22814 argument, local variables, and return value.
22816 * lisp.h: Update prototypes of emacs_write and emacs_read.
22818 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22820 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22822 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22824 Fix more problems found by GCC 4.6.0's static checks.
22826 * xdisp.c (vmessage): Use a better test for character truncation.
22828 * charset.c (load_charset_map): <, not <=, for optimization,
22829 and to avoid potential problems with integer overflow.
22830 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22831 * casetab.c (set_identity, shuffle): Likewise.
22832 * editfns.c (Fformat): Likewise.
22833 * syntax.c (skip_chars): Likewise.
22835 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22836 This also lets GCC 4.6.0 generate slightly better loop code.
22838 * callint.c (Fcall_interactively): <, not <=, for optimization.
22839 (Fcall_interactively): Count the number of arguments produced,
22840 not the number of arguments given. This is simpler and lets GCC
22841 4.6.0 generate slightly better code.
22843 * ftfont.c: Distingish more carefully between FcChar8 and char.
22844 The previous code passed unsigned char * to a functions like
22845 strlen and xstrcasecmp that expect char *, which does not
22846 conform to the C standard.
22847 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22848 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22849 char * when the C standard requires it.
22851 * keyboard.c (read_char): Remove unused var.
22853 * eval.c: Port to Windows vsnprintf (Bug#8435).
22854 Include <limits.h>.
22855 (SIZE_MAX): Define if the headers do not.
22856 (verror): Do not give up if vsnprintf returns a negative count.
22857 Instead, grow the buffer. This ports to Windows vsnprintf, which
22858 does not conform to C99. Problem reported by Eli Zaretskii.
22859 Also, simplify the allocation scheme, by avoiding the need for
22860 calling realloc, and removing the ALLOCATED variable.
22862 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22864 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22865 But keep the doprint source code for now, as we might revamp it
22866 and use it again (Bug#8435).
22867 * lisp.h (doprnt): Remove.
22868 * Makefile.in (base_obj): Remove doprnt.o.
22869 * deps.mk (doprnt.o): Remove.
22871 error: Print 32- and 64-bit integers portably (Bug#8435).
22872 Without this change, on typical 64-bit hosts error ("...%d...", N)
22873 was used to print both 32- and 64-bit integers N, which relied on
22874 undefined behavior.
22875 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22876 * lisp.h (error, verror): Mark as printf-like functions.
22877 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22878 Report overflow in size calculations when allocating printf buffer.
22879 Do not truncate output string at its first null byte.
22880 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22881 Truncate the output at a character boundary, since vsnprintf does not
22883 * charset.c (check_iso_charset_parameter): Convert internal
22884 character to string before calling 'error', since %c now has the
22886 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22887 overflow when computing char to be passed to 'error'. Do not
22888 pass Lisp_Object to 'error'; pass the integer instead.
22889 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22890 formatted with plain %d.
22892 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22894 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22896 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22898 * xterm.c (x_catch_errors): Remove duplicate declaration.
22900 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22902 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22904 2011-04-10 Jim Meyering <meyering@redhat.com>
22906 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22907 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22908 return ssize_t not "int", and use size_t as the buffer length.
22909 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22910 * gnutls.h: Update declarations.
22911 * process.c (read_process_output): Use ssize_t, to match.
22912 (send_process): Likewise.
22914 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22916 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22918 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22920 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22921 Use unsigned char, to match FcChar8 type definition.
22923 * xterm.c (handle_one_xevent):
22924 * xmenu.c (create_and_show_popup_menu):
22925 * xselect.c (x_decline_selection_request)
22926 (x_reply_selection_request): Avoid type-punned deref of X events.
22928 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22930 Fix some uses of `int' instead of EMACS_INT.
22931 * search.c (string_match_1, fast_string_match)
22932 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22933 (scan_buffer, find_next_newline_no_quit)
22934 (find_before_next_newline, search_command, Freplace_match)
22935 (Fmatch_data): Make some `int' variables be EMACS_INT.
22937 * xdisp.c (display_count_lines): 3rd argument and return value now
22938 EMACS_INT. All callers changed.
22939 (pint2hrstr): Last argument is now EMACS_INT.
22941 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22942 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22943 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

22957 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22958 (encode_invocation_designation): Last argument P_NCHARS is now
22960 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22961 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22963 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22966 * ccl.c (Fccl_execute_on_string): Declare some variables
22969 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22971 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22973 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22975 * process.c (Fformat_network_address): Doc fix.
22977 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22979 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22981 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22983 * keyboard.c (read_char): Call Lisp function help-form-show,
22984 instead of using internal_with_output_to_temp_buffer.
22985 (Qhelp_form_show): New var.
22986 (syms_of_keyboard): Use DEFSYM macro.
22988 * print.c (internal_with_output_to_temp_buffer): Function deleted.

22995 (list_processes_1): Delete.
22997 2011-04-06 Eli Zaretskii <eliz@gnu.org>
22999 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
23001 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
23003 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
23005 Fix more problems found by GCC 4.6.0's static checks.

23027 This avoids several warnings with gcc -Wstrict-overflow.
23028 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
23029 directly, rather than having caller test rule sign. This avoids
23030 some unnecessary tests.
23031 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
23032 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
23033 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
23035 * xfont.c (xfont_text_extents): Remove var that was set but not used.
23036 (xfont_open): Avoid unnecessary tests.
23038 * composite.c (composition_gstring_put_cache): Use unsigned integer.
23040 * composite.h, composite.c (composition_gstring_put_cache):
23041 Use EMACS_INT, not int, for length.
23043 * composite.h (COMPOSITION_DECODE_REFS): New macro,
23044 breaking out part of COMPOSITION_DECODE_RULE.
23045 (COMPOSITION_DECODE_RULE): Use it.
23046 * composite.c (get_composition_id): Remove unused local vars,
23047 by using the new macro.
23049 * textprop.c (set_text_properties_1): Change while to do-while,
23050 since the condition is always true at first.
23052 * intervals.c (graft_intervals_into_buffer): Mark var as used.
23053 (interval_deletion_adjustment): Return unsigned value.
23056 * process.c (list_processes_1, create_pty, read_process_output):
23057 (exec_sentinel): Remove vars that were set but not used.
23058 (create_pty): Remove unnecessary "volatile"s.
23059 (Fnetwork_interface_info): Avoid possibility of int overflow.
23060 (read_process_output): Do adaptive read buffering even if carryover.
23061 (read_process_output): Simplify nbytes computation if buffered.

23069 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
23070 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
23072 * print.c (print_error_message): Avoid int overflow.
23074 * font.c (font_list_entities): Redo for clarity,
23075 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
23077 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
23078 (font_score): Avoid potential overflow in diff calculation.
23080 * fns.c (substring_both): Remove var that is set but not used.
23081 (sxhash): Redo loop for clarity and to avoid wraparound warning.
23083 * eval.c (funcall_lambda): Rename local to avoid shadowing.
23085 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
23086 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
23087 can always succeed if overflow has undefined behavior.
23089 * search.c (boyer_moore, wordify): Remove vars set but not used.
23090 (wordify): Omit three unnecessary tests.
23092 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
23093 All callers changed. This avoids the need for an unused var.
23095 * casefiddle.c (casify_region): Remove var that is set but not used.
23097 * dired.c (file_name_completion): Remove var that is set but not used.
23099 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
23101 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
23102 (Finsert_file_contents): Remove unnecessary code checking fd.
23104 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
23105 Check for integer overflow on size calculations.
23107 * buffer.c (Fprevious_overlay_change): Remove var that is set
23110 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
23111 Remove vars that are set but not used.
23112 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
23113 (timer_check_2): Mark vars as initialized.
23115 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
23117 * image.c (lookup_image): Remove var that is set but not used.
23118 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
23120 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
23121 that are set but not used.
23123 * xfns.c (make_invisible_cursor): Don't return garbage
23124 if XCreateBitmapFromData fails (Bug#8410).
23126 * xselect.c (x_get_local_selection, x_handle_property_notify):
23127 Remove vars that are set but not used.
23129 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
23130 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
23132 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
23133 Remove var that is set but not used.
23134 (scroll_bar_windows_size): Now size_t, not int.
23135 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
23136 Check for overflow.
23138 * xfaces.c (realize_named_face): Remove vars that are set but not used.
23139 (map_tty_color) [!defined MSDOS]: Likewise.
23141 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
23143 * coding.c: Remove vars that are set but not used.
23144 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
23145 All callers changed.
23146 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
23147 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
23148 (decode_coding_charset): Remove vars that are set but not used.
23150 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
23151 that is set but not used.
23153 * print.c (print_object): Remove var that is set but not used.
23155 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
23156 The gnulib version avoids calling malloc in the usual case,
23157 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
23158 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
23159 * filelock.c (current_lock_owner): Likewise.
23160 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
23161 * sysdep.c: Include allocator.h, careadlinkat.h.
23162 (emacs_no_realloc_allocator): New static constant.
23163 (emacs_readlink): New function.
23164 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
23165 ../lib/careadlinkat.h.
23167 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
23169 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
23170 first non-nil return value).
23172 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
23174 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
23175 if not defined (Bug#8403).
23177 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
23179 * xdisp.c (display_count_lines): Remove parameter `start',
23180 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
23181 (get_char_face_and_encoding): Remove parameter `multibyte_p',
23182 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

23184 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
23185 and thereabouts. All callers changed.
23186 (get_per_char_metric): Remove parameter `f', unused since
23187 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
23189 2011-04-02 Jim Meyering <meyering@redhat.com>
23191 do not dereference NULL upon failed strdup
23192 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
23193 (ns_get_family): Likewise.
23195 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
23197 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
23199 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
23201 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
23204 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
23206 Add lexical binding.
23208 * window.c (Ftemp_output_buffer_show): New fun.
23209 (Fsave_window_excursion):
23210 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
23212 * lread.c (lisp_file_lexically_bound_p): New function.
23213 (Fload): Bind Qlexical_binding.
23214 (readevalloop): Remove `evalfun' arg.
23215 Bind Qinternal_interpreter_environment.
23216 (Feval_buffer): Bind Qlexical_binding.
23217 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
23219 (syms_of_lread): Declare `lexical-binding'.
23221 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
23223 * keyboard.c (eval_dyn): New fun.
23224 (menu_item_eval_property): Use it.
23226 * image.c (parse_image_spec): Use Ffunctionp.
23228 * fns.c (concat, mapcar1): Accept byte-code-functions.
23230 * eval.c (Fsetq): Handle lexical vars.
23231 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
23232 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
23233 (FletX, Flet): Obey lexical binding.
23234 (Fcommandp): Handle closures.
23235 (Feval): New `lexical' arg.
23236 (eval_sub): New function extracted from Feval. Use it almost
23237 everywhere where Feval was used. Look up vars in lexical env.
23239 (Ffunctionp): Move from subr.el.
23240 (Ffuncall): Handle closures.
23241 (apply_lambda): Remove `eval_flags'.
23242 (funcall_lambda): Handle closures and new byte-code-functions.
23243 (Fspecial_variable_p): New function.
23244 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
23245 but without exporting it to Lisp.
23247 * doc.c (Fdocumentation, store_function_docstring):
23248 * data.c (Finteractive_form): Handle closures.
23250 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
23253 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
23255 (exec_byte_code): New function extracted from Fbyte_code to handle new
23256 calling convention for byte-code-functions. Add new byte-codes.
23258 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
23260 * alloc.c (Fmake_symbol): Init new `declared_special' field.
23262 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
23264 * xdisp.c (redisplay_internal): Fix prototype.
23266 2011-03-31 Eli Zaretskii <eliz@gnu.org>
23268 * xdisp.c (SCROLL_LIMIT): New macro.
23269 (try_scrolling): Use it when setting scroll_limit.
23270 Limit scrolling to 100 screen lines.
23271 (redisplay_window): Even when falling back on "recentering",
23272 position point in the window according to scroll-conservatively,
23273 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
23275 (try_scrolling): When point is above the window, allow searching
23276 as far as scroll_max, or one screenful, to compute vertical
23277 distance from PT to the scroll margin position. This prevents
23278 try_scrolling from unnecessarily failing when
23279 scroll-conservatively is set to a value slightly larger than the
23280 window height. Clean up the case of PT below the margin at bottom
23281 of window: scroll_max can no longer be INT_MAX. When aggressive
23282 scrolling is in use, don't let point enter the opposite scroll
23283 margin as result of the scroll.
23284 (syms_of_xdisp) <scroll-conservatively>: Document the
23285 threshold of 100 lines for never-recentering scrolling.
23287 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
23289 * dispextern.h (move_it_by_lines):

23292 (message_log_check_duplicate): Remove parameters `prev_bol' and
23293 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
23294 (redisplay_internal): Remove parameter `preserve_echo_area',
23295 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
23297 * indent.c (Fvertical_motion):
23298 * window.c (window_scroll_pixel_based, Frecenter):
23299 Don't pass `need_y_p' to `move_it_by_lines'.
23301 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
23303 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
23304 steal a few bits to be more compact.
23305 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
23306 Remove unneeded casts.
23308 * bytecode.c (Fbyte_code): CAR and CDR can GC.
23310 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
23312 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
23313 binding" message (bug#7967).
23315 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
23317 Fix more problems found by GCC 4.6.0's static checks.
23319 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
23320 Remove unused local var.
23322 * editfns.c (Fmessage_box): Remove unused local var.
23324 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
23325 (note_mode_line_or_margin_highlight, note_mouse_highlight):
23326 Omit unused local vars.
23327 * window.c (shrink_windows): Omit unused local var.
23328 * menu.c (digest_single_submenu): Omit unused local var.
23329 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
23330 Omit unused local var.
23332 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
23333 Don't assume string length fits in int.
23334 (keyremap_step, read_key_sequence): Use size_t for sizes.
23335 (read_key_sequence): Don't check last_real_key_start redundantly.
23337 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
23338 instead of alloca (Bug#8344).
23340 * eval.c (Fbacktrace): Don't assume nargs fits in int.
23341 (Fbacktrace_frame): Don't assume nframes fits in int.
23343 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
23345 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
23348 * term.c (produce_glyphless_glyph): Remove unnecessary test.
23350 * cm.c (calccost): Turn while-do into do-while, for clarity.
23352 * keyboard.c (syms_of_keyboard): Use the same style as later
23353 in this function when indexing through an array. This also
23354 works around GCC bug 48267.
23356 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
23358 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
23360 * chartab.c (sub_char_table_ref_and_range): Redo for slight
23361 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
23363 * keyboard.c, keyboard.h (num_input_events): Now size_t.
23364 This avoids undefined behavior on integer overflow, and is a bit
23365 more convenient anyway since it is compared to a size_t variable.
23367 Variadic C functions now count arguments with size_t, not int.
23368 This avoids an unnecessary limitation on 64-bit machines, which
23369 caused (substring ...) to crash on large vectors (Bug#8344).
23370 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
23371 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

23379 * fns.c (concat): Likewise.
23380 * frame.c (x_set_frame_parameters): Likewise.
23381 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
23382 0 if not found, not -1. All callers changed.
23384 * alloc.c (garbage_collect): Don't assume stack size fits in int.
23385 (stack_copy_size): Now size_t, not int.
23386 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
23388 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
23390 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
23391 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
23392 All callers changed.
23394 * lisp.h (multibyte_char_to_unibyte):
23395 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
23396 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

23407 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
23408 don't set the hook to nil, but remove the offending function instead.
23409 (Qcommand_hook_internal): Remove, unused.
23410 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
23411 Vcommand_hook_internal.
23413 * eval.c (enum run_hooks_condition): Remove.
23414 (funcall_nil, funcall_not): New functions.
23415 (run_hook_with_args): Call each function through a `funcall' argument.
23416 Remove `cond' argument, now redundant.

23429 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
23430 All callers changed.
23432 * w32.c (_wsa_errlist): Use braces for struct initializers.
23434 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
23435 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
23436 All callers changed.

23592 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
23594 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
23595 unconditionally since it does the check itself.
23597 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
23599 Fix more problems found by GCC 4.5.2's static checks.
23601 * coding.c (encode_coding_raw_text): Avoid unnecessary test
23602 the first time through the loop, since we know p0 < p1 then.
23603 This also avoids a gcc -Wstrict-overflow warning.
23605 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
23606 leading to a memory leak, possible in functions like
23607 load_charset_map_from_file that can allocate an unbounded number
23608 of objects (Bug#8318).
23610 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
23611 that could (at least in theory) be that large.
23613 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
23614 This is less likely to overflow, and avoids undefined behavior if
23615 overflow does occur. All callers changed. Use strtoul to scan
23616 for the unsigned long integer.
23617 (pint2hrstr): Simplify and tune code slightly.
23618 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

23628 * fileio.c (Fcopy_file): Report error if fchown or fchmod
23631 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
23633 * process.c (Fmake_network_process): Use socklen_t, not int,
23634 where POSIX says socklen_t is required in portable programs.
23635 This fixes a porting bug on hosts like 64-bit HP-UX, where
23636 socklen_t is wider than int (Bug#8277).
23637 (Fmake_network_process, server_accept_connection):
23638 (wait_reading_process_output, read_process_output):
23641 * process.c: Rename or move locals to avoid shadowing.

23651 Make tparam.h and terminfo.c consistent.
23652 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23653 Include tparam.h instead, since it declares them.
23654 * cm.h (PC): Remove extern decl; tparam.h now does this.
23655 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23656 * terminfo.c: Include tparam.h, to check interfaces.
23657 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23658 (tparam): Adjust signature to match interface in tparam.h;
23659 this removes some undefined behavior. Check that outstring and len
23660 are zero, which they always are with Emacs.
23661 * tparam.h (PC, BC, UP): New extern decls.
23663 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
23664 (xftfont_open): Rename locals to avoid shadowing.
23666 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

23678 * composite.c (composition_compute_stop_pos): Rename local to
23680 (composition_reseat_it): Remove unused locals.
23681 (find_automatic_composition, composition_adjust_point): Likewise.
23682 (composition_update_it): Mark var as initialized.
23683 (find_automatic_composition): Mark vars as initialized,
23684 with a FIXME (Bug#8290).

23688 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
23689 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
23690 (BUF_DEC_POS): Be more systematic about renaming local temporaries
23691 to avoid shadowing.
23693 * textprop.c (property_change_between_p): Remove; unused.
23695 * intervals.c (interval_start_pos): Now static.
23697 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

23703 Fix pointer signedness.
23704 (alsa_choose_format): Remove unused local var.
23705 (wav_play): Initialize a variable to 0, to prevent undefined
23706 behavior (Bug#8278).
23708 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23710 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23712 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23713 clobbering (Bug#8298).
23714 * sysdep.c (sys_subshell): Likewise.
23715 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23717 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23718 This should get cleaned up, so that child_setup has the
23719 same signature on all platforms.
23721 * callproc.c (call_process_cleanup): Now static.
23722 (relocate_fd): Rename locals to avoid shadowing.
23724 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
23726 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
23727 not to be necessary, and produces flickering.
23729 2011-03-20 Glenn Morris <rgm@gnu.org>
23731 * config.in: Remove file.
23733 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
23735 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
23736 are now in src/globals.h.
23737 (syms_of_minibuf): Remove spurious & from previous change.

23763 (sigchld_handler): Now static.
23765 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
23766 That way, the code declares only the vars that it needs.

23777 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
23778 Define only if needed.
23780 * unexelf.c (unexec): Name an expression,
23781 to avoid gcc -Wbad-function-cast warning.
23782 Use a different way to cause a compilation error if anyone uses
23783 n rather than nn, a way that does not involve shadowing.
23784 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
23786 * deps.mk (unexalpha.o): Remove; unused.
23788 New file unexec.h, the (simple) interface for unexec (Bug#8267).

23855 (Ftranslate_region_internal, Fformat):
23856 Rename or remove local vars to avoid shadowing.

23859 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
23862 * lisp.h (eassert): Check that the argument compiles, even if
23863 ENABLE_CHECKING is not defined.
23865 * data.c (Findirect_variable): Name an expression, to avoid
23866 gcc -Wbad-function-cast warning.

23883 (Fmemory_limit): Cast sbrk's returned value to char *.

23909 (RETALLOC_IF): Define only if needed.
23910 (WORDCHAR_P): Likewise. This one is never needed, but is used
23911 only in a comment talking about a compiler bug, so put inside
23912 the #if 0 of that comment.

23941 New macros, so that the caller can use some names other than
23942 gcpro1, gcpro2, etc.
23943 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23945 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23946 argument, for consistency with GCPRO2_VAR, etc: it is now the

23950 Rename locals to avoid shadowing.
23952 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23953 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23954 dired.c's scmp function, had undefined behavior.

23956 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23957 * buffer.h: ... to here, because these macros use current_buffer,
23958 and the new implementation with inline functions needs to have
23959 current_buffer in scope now, rather than later when the macros
23961 (downcase, upcase1): New static inline functions.
23962 (DOWNCASE, UPCASE1): Reimplement using these functions.
23963 This avoids undefined behavior in expressions like

23978 (file_name_as_directory): Use const pointers when appropriate.
23979 (Fexpand_file_name): Likewise. In particular, newdir might
23980 point at constant storage, so make it a const pointer.

23994 so that gcc does not warn that these functions aren't declared.

23997 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
23998 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.

24004 * buffer.c (fix_overlays_before): Mark locals as initialized.
24005 (fix_start_end_in_overlays): Likewise. This function should be
24006 simplified by using pointers-to-pointers, but that's a different

24009 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
24010 (report_overlay_modification): Rename locals to avoid shadowing.

24015 to suppress a gcc -Wclobbered warning that does not seem to be right.
24016 (MAXPATHLEN): Define only if needed.
24018 * process.c (serial_open, serial_configure): Move decls from here ...
24019 * systty.h: ... to here, so that they can be checked.
24021 * fns.c (get_random, seed_random): Move extern decls from here ...

24033 (describe_map_tree):
24034 Rename locals to avoid shadowing.

24365 a block, when the outer 'i' will do.

24378 -Wuninitialized does not deduce are never used uninitialized.
24379 (detect_coding_iso_2022): Initialize a local variable that might
24380 be used uninitialized. Leave a FIXME because it's not clear that
