134 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
135 too so that these builds can use Cygwin's file conversion
136 functions. (We've been building and linking cygw32.o all along
137 and just not using it.)
139 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
141 File synchronization fixes (Bug#13944).
142 * Makefile.in (LIB_FDATASYNC): New macro.

152 * w32term.c (w32_read_socket): If the Emacs frame is being
153 activated, call w32fullscreen_hook, to make sure the new frame
154 dimensions are in effect. (Bug#13937)
156 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
158 * xdisp.c (init_iterator): Simplify because both character and byte
159 positions are either specified or -1. Add eassert. Adjust comment.
160 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
161 character and byte positions can be obtained from marker.

178 a function pointer type; the C Standard requires this.
180 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
181 Include <sys/param.h> unconditionally, as that works elsewhere and
182 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
183 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
186 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>

215 common file dialog code.
217 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
218 can just use du like other systems.
220 * coding.c (from_unicode_buffer): Declare.
221 * coding.c (from_unicode_buffer): Implement.
223 2013-03-10 Stefan Monnier <monnier@iro.umontreal.ca>

264 (adjust_after_insert): Call adjust_after_replace with the new arg
267 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
269 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
270 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
271 from Elisp via unread-command-events.
273 * keyboard.c (access_keymap_keyremap): Accept nil return value from
274 functions to mean "no change".
276 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
278 region-cache.c, scroll.c, search.c: Use bool for booleans.

281 * search.c (struct regexp_cache, compile_pattern_1)
282 (compile_pattern, string_match_1, search_command)
283 (trivial_regexp_p, search_buffer, Freplace_match, match_limit)
284 (search_regs_saved, Fregexp_quote):
285 Use bool for boolean.
286 * region-cache.c (region_cache_forward, region_cache_backward):
287 Fix comments to match code: these functions return int, not boolean.
289 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
291 * search.c (find_newline): Accept start and end byte positions
292 as arguments and allow -1 if not known.

298 Adjust call to find_newline.
299 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

302 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
303 (get_visually_first_element, move_it_vertically_backward): Likewise.
304 Obtain byte position from the display iterator, where appropriate.
306 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>

327 to match other functions accepting character and byte positions.
329 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.

331 when you need just to move to the previous buffer position.
332 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
334 2013-03-07 Eli Zaretskii <eliz@gnu.org>

407 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
409 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
410 * sysdep.c (list_system_processes)
411 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
412 Make it a stub in this case; otherwise the build might fail,
413 and this code hasn't been tested on such hosts anyway.
414 Problem reported by Nelson H. F. Beebe in
415 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
416 and analyzed by Jérémie Courrèges-Anglas in
417 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
419 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
421 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
422 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
423 (get_visually_first_element, move_it_vertically_backward): Ajust users.
424 * bidi.c (bidi_find_paragraph_start): Likewise.
425 * indent.c (vmotion): Likewise.
427 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
429 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
430 * filelock.c: Include <c-ctype.h>.
431 (MAX_LFINFO): New top-level constant.
432 (lock_info_type): Remove members pid, boot_time. Add members at,
433 dot, colon. Change user member to be the entire buffer, not a
434 pointer. This allows us to handle the case where a foreign
435 pid or boot time exceeds the local range. All uses changed.
436 (LINKS_MIGHT_NOT_WORK): New constant.
437 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
438 (defined_WINDOWSNT): Remove.
439 (MAKE_LOCK_NAME, file_in_lock_file_name):
440 Always use .#FILE (not .#-FILE) for the file lock,
441 even if it is a regular file.
442 (rename_lock_file): New function.
443 (create_lock_file): Use it.
444 (create_lock_file, read_lock_data):
445 Prefer a symbolic link for the lock file, falling back on a
446 regular file if symlinks don't work. Do not try to create
447 symlinks on MS-Windows, due to security hassles. Stick with
448 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
449 link, rename, unlink, mkstemp) when creating locks, as a GNUish
450 host may be using a Windowsish file system, and cannot use
451 MS-Windows-only system calls. Fall back on mktemp if mkstemp
452 doesn't work. Don't fail merely because of a symlink-contents
453 length limit in the current file system; fall back on regular
454 files. Increase the symlink contents length limit to 8 KiB, this
455 should be big enough for any real use and doesn't crunch the
457 (create_lock_file, lock_file_1, read_lock_data):
458 Simplify allocation of lock file buffers now that they fit in 8 KiB.
459 (lock_file_1): Return error number, not bool. All callers changed.
460 (ELOOP): New macro, if not already defined.
461 (read_lock_data): Return size of lock file contents, not Lisp object.
462 All callers changed. Handle a race condition if some other process
463 replaces a regular-file lock with a symlink lock or vice versa,
464 while we're trying to read the lock.
465 (current_lock_owner): Parse contents more carefully, to help avoid
466 confusing a regular-file lock with some other application's use
467 of the file. Check for lock file contents being too long, or
468 not parsing correctly.
469 (current_lock_owner, lock_file):
470 Allow foreign pid and boot times that exceed the local range.
471 (current_lock_owner, lock_if_free, lock_file):
472 Simplify allocation of lock file contents.
473 * w32.c (sys_rename_replace): New function, containing most of
474 the contents of the old sys_rename.
475 (sys_rename): Use it.
476 (fchmod): New dummy function.
477 * w32.h (sys_rename_replace, fchmod): New decls.
479 2013-03-05 Eli Zaretskii <eliz@gnu.org>
481 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
482 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
483 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
484 <dmantipov@yandex.ru>.
486 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
488 * composite.c (get_composition_id, fill_gstring_header):
489 Use make_uninit_vector where appropriate.
490 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
491 * xselect.c (clean_local_selection_data): Likewise.
493 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
495 Fix misuse of ImageMagick that caused core dump (Bug#13846).
496 * image.c (imagemagick_load_image): Calculate height and width
497 after flattening the image, not before.
499 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
501 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
502 * ftfont.c (ftfont_shape_by_flt): Likewise.
503 * w32uniscribe.c (uniscribe_shape): Likewise.
505 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
507 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
508 The old approach, which fell back on DIR/.#FILE.0 through
509 DIR/.#FILE.9, had race conditions that could not be easily fixed.
510 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
511 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
512 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
513 because the locking mechanism was never reliable in that case).
514 This patch fixes this and other bugs discovered by a code
515 inspection that was prompted by
516 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
517 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
518 to avoid interoperability problems between the MS-Windows and
519 non-MS-Windows implementations. MS-Windows and non-MS-Windows
520 instances of Emacs now ignore each others' locks.
521 * filelock.c (defined_WINDOWSNT): New constant.
522 (MAKE_LOCK_NAME, fill_in_lock_file_name):
523 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
524 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
525 regular files on MS-Windows hosts.
526 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
527 Use SAFE_ALLOCA to avoid problems with long file names.
528 (MAX_LFINFO): Now a local constant, not a global macro.
529 (IS_LOCK_FILE): Remove.
530 (lock_file_1): Don't inspect errno if symlink call succeeds;
532 (lock_file): Document that this function can return if lock
534 (lock_file): Don't access freed storage.
536 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

540 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
542 * textprop.c: Use bool for booleans.
543 (validate_interval_range, Fadd_text_properties)
544 (Fremove_text_properties): Prefer bool to int when either works.
546 2013-03-02 Eli Zaretskii <eliz@gnu.org>
548 * textprop.c (Fadd_text_properties, Fremove_text_properties):
549 If the interval tree changes as a side effect of calling
550 modify_region, re-do processing starting from the call to
551 validate_interval_range. (Bug#13743)
553 2013-02-28 Eli Zaretskii <eliz@gnu.org>
555 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
558 2013-02-27 Eli Zaretskii <eliz@gnu.org>
560 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
561 _SH_DENYRW flag, instead of emacs_open, to deny any other process
562 access to the lock file until it is written and closed.
565 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
567 * callint.c (Qcall_interactively):
568 * macros.c (Qexecute_kbd_macro):

573 * window.c (Frecenter): Tiny docstring enhancement.
575 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
577 Minor textprop integer cleanup.
578 * intervals.h, textprop.c (add_text_properties_from_list):
579 Return void, not int, since nobody uses the return value.
580 * textprop.c (validate_plist, add_properties, remove_properties)
581 (Fadd_text_properties):
582 Don't assume list length fits in int.
583 (interval_has_all_properties, interval_has_some_properties)
584 (interval_has_some_properties_list, add_properties, remove_properties)
585 (Fadd_text_properties, Fremove_text_properties)
586 (Fremove_list_of_text_properties, text_property_stickiness):
587 Use bool for booleans.
588 (Fadd_text_properties, Fremove_text_properties):
589 (Fremove_list_of_text_properties):
590 Reindent do-while as per GNU style.
592 2013-02-25 Eli Zaretskii <eliz@gnu.org>
594 Implement CLASH_DETECTION for MS-Windows.
596 * filelock.c [WINDOWSNT]: Include w32.h.
597 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
598 function of that name. Up-case the macro arguments.
599 (IS_LOCK_FILE): New macro.
600 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
601 (create_lock_file): New function, with body extracted from
603 [WINDOWSNT]: Implement lock files by writing a regular file with
604 the lock information as its contents.
605 (read_lock_data): New function, on Posix platforms just calls
607 [WINDOWSNT]: Read the lock info from the file.
608 (current_lock_owner): Call read_lock_data instead of calling
609 emacs_readlinkat directly.
610 (lock_file) [WINDOWSNT]: Run the file name through
613 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
614 just check if the process by that PID exists.
616 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
617 also present, as doing so will fail to error out if the file
620 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
622 * textprop.c (Fadd_text_properties, Fremove_text_properties)
623 (Fremove_list_of_text_properties): Skip all of the intervals in
624 the region between START and END that already have resp. don't
625 have the requested properties, not just the first one.
626 Add assertions that the loop afterwards always modifies the
627 properties. (Bug#13743)
629 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
631 * callint.c (Fcall_interactively): Use the right lexical environment

639 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
640 (START_FILES): Remove. All uses removed.
641 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
642 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
643 (buildobj.h): Use it.
644 ($(ALLOBJS)): Depend on globals.h.
645 (temacs$(EXEEXT)): Use $(ALLOBJS).
646 * autodeps.mk (ALLOBJS): Move to Makefile.in.
647 * deps.mk (vm-limit.o):

651 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
652 [__GNUC__ && !ORDINARY_LINK]: Remove.

656 (make_hdr): Use DATA_START instead of start_of_data.
657 * vm-limit.c: Move most of mem-limits.h's contents here.
658 (data_start): New decl. It's OK if this is approximate,
659 so simplify-away some unnecessary exactness.
660 (POINTER): Remove; all uses removed.
661 (data_space_start): Now char *, to avoid casts.
662 (exceeds_lisp_ptr): New function, replacing the old
663 EXCEEDS_LISP_PTR macro. All uses changed.
664 (check_memory_limits): Simplify and remove casts.
665 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

670 * xdisp.c (set_message): Only check for debug-on-message if STRING
671 is a string. (Bug#13797)
673 2013-02-24 Paul Eggert <eggert@cs.ucla.edu>

676 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
677 2012-07-10 patch to this file. Reported by Eli Zaretskii in
678 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
679 and diagnosed by Andreas Schwab in
680 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.

684 Assume C89 or better.
685 * ralloc.c (SIZE, POINTER, NIL):
686 * vm-limit.c (POINTER):
687 Remove, replacing all uses with C89 equivalents. These old
688 symbols were present only for porting to pre-C89 platforms.
690 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
692 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
693 This avoids warning messages reported as part of Bug#13546.
695 2013-02-21 Ken Brown <kbrown@cornell.edu>

706 (syms_of_keyboard): Adjust accordingly.
708 2013-02-19 Daniel Colascione <dancol@dancol.org>
710 * sheap.c (report_sheap_usage): Use message, not message1, so
711 that we don't try to create a buffer while we're in the middle
712 of dumping Emacs. Explain why.
714 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
716 * search.c (find_newline): Return byte position in bytepos.

726 (get_visually_first_element, move_it_vertically_backward):
727 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
729 2013-02-19 Eli Zaretskii <eliz@gnu.org>
731 * w32proc.c (new_child): Avoid leaking handles if the subprocess
732 resources were not orderly released.

737 the leftmost nor the rightmost, redraw both the left and the right
738 vertical borders. (Bug#13723)

760 * w32.c (sys_chown): Remove unused function.
762 * w32term.c <input_signal_count>: Declare 'volatile'
763 unconditionally. (Bug#9066)
765 * w32.c (set_errno): Reset h_errno and don't set it to any other
766 value. Set errno instead.
767 (check_errno): Reset h_errno.

782 when auto-save-timeout is less than 4. (Bug#13720)
784 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

811 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
813 Fix AIX port (Bug#13650).
814 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
815 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
816 was #undeffed earlier, so it cannot be used as a macro here.
817 Use the constant and not the macro.
819 2013-02-15 Eli Zaretskii <eliz@gnu.org>
821 * w32proc.c (new_child): If no vacant slots are found in
822 child_procs[], make another pass looking for slots whose process
823 has exited or died. (Bug#13546)
825 * w32.c (sys_pipe): When failing due to file descriptors above
826 MAXDESC, set errno to EMFILE.
827 (_sys_read_ahead): Update cp->status when failing to read serial
828 communications input, so that the status doesn't stay at
829 STATUS_READ_IN_PROGRESS. (Bug#13546)
831 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
833 * gtkutil.c (tb_size_cb): New function.
834 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).

838 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
841 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
843 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
845 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
847 * font.c (font_range): Add pos_byte argument. Adjust comment
849 * font.h (font_range): Adjust prototype.
850 * composite.c (autocmp_chars): Pass byte position to font_range.
851 Break long line. Remove useless prototype and format comment.
853 2013-02-13 Glenn Morris <rgm@gnu.org>
855 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
857 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
859 Improve AIX port some more (Bug#13650).
860 With this, it should be as good as it was in 23.3, though it's
861 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
862 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
863 * unexaix.c (start_of_text): Remove.
864 (_data, _text): Declare as char[], not int, as AIX manual suggests.
865 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
866 (orig_load_scnptr, orig_data_scnptr):
867 Now off_t, not long, since they are file offsets.
868 (make_hdr): Use _data, not start_of_data ().
869 This is the key part of the fix.
870 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
871 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
873 * pre-crt0.c (data_start): Initialize to 1.
874 This ports to compilers that optimize the external declaration
875 'int x = 0;' as if it were 'int x;' to shrink the executable.
877 Improve AIX port (Bug#13650).
878 This doesn't fix the bug, but it makes progress: Emacs builds now.
879 * unexaix.c: Include inttypes.h, stdarg.h.
880 (report_error, report_error_1): Mark as _Noreturn.
881 (report_error): Don't report the wrong errno.
882 (report_error_1): Now varargs. All callers changed.
883 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
884 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
885 (write_ptr): Use %p to print address rather than %lx and a cast
886 to unsigned long. Grow buffer a bit, to be safer.
888 2013-02-13 Eli Zaretskii <eliz@gnu.org>
890 * bidi.c (bidi_resolve_neutral): After finding the next
891 non-neutral character, accept NEUTRAL_ON type as well, because
892 directional control characters, such as LRE and RLE, have their
893 type converted to that by bidi_resolve_weak. This avoids aborts
894 when LRE/RLE follows a run of neutrals.
895 (bidi_move_to_visually_next): Assert that return value of
896 bidi_peek_at_next_level is non-negative. Negative values will
899 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
901 Minor getenv-related fixes.
902 * callproc.c (Fcall_process_region) [!DOS_NT]:
903 Avoid unnecessary duplicate call to getenv.
904 * callproc.c (init_callproc):
905 * dispnew.c (init_display):
906 * sysdep.c (sys_subshell):
907 Omit unnecessary cast of getenv or egetenv.
909 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
911 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
914 2013-02-12 Eli Zaretskii <eliz@gnu.org>
916 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
918 (display_line): Set w->region_showing to the value of
919 it->region_beg_charpos, not to -1. This fixes redisplay
920 optimization when cursor is moved up after M->. (Bug#13623)
922 (try_scrolling): Scroll text up more if point is too close to ZV
923 and inside the scroll margin. This makes sure point is moved
924 outside the scroll margin in these cases.
926 * window.h (struct window): region_showing can no longer be
929 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
931 Tune by using memchr and memrchr.
932 * doc.c (Fsnarf_documentation):
933 * fileio.c (Fsubstitute_in_file_name):
934 * search.c (find_newline, scan_newline):
935 * xdisp.c (pos_visible_p, display_count_lines):
936 Use memchr and memrchr rather than scanning byte-by-byte.
937 * search.c (find_newline): Rename from scan_buffer.
938 Omit first arg TARGET, as it's always '\n'. All callers changed.
940 Clean up read_key_sequence a tiny bit more.
941 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
942 (read_key_sequence): Remove unused locals.
944 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
946 Clean up read_key_sequence a bit; reread active keymaps after first event.
947 * keyboard.c (read_char, read_char_x_menu_prompt)
948 (read_char_minibuf_menu_prompt):
949 Replace nmaps+maps with a single `map' arg.
950 (follow_key): Operate on a single map.
951 (active_maps): New function.
952 (test_undefined): Also return true for nil bindings.
953 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
954 a single (composed) keymap. Remember `first_event' to choose the right
955 set of active keymaps. Recompute the set of keymaps after receiving
956 the first event. Remove GOBBLE_FIRST_EVENT.
957 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
958 * keyboard.h (read_char): Update declaration.
959 * lread.c (read_filtered_event): Adjust call to read_char.

967 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
969 * marker.c (set_marker_internal): If desired position is passed
970 as a marker, avoid call to buf_charpos_to_bytepos.

976 * xdisp.c (message_dolog): Likewise.
978 2013-02-10 Eli Zaretskii <eliz@gnu.org>
980 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
981 When text lines are longer than window's screen lines, don't move back
982 too far. This speeds up some redisplay operations. (Bug#13675)

998 (sxhash_float): Return EMACS_UINT, for consistency with the other
1000 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1001 non-static inline function and therefore can't use static vars.
1002 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1003 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1004 with the other hash functions.
1006 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1008 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1009 XXXXXX part of the temporary file pattern is not downcased even
1010 when w32-downcase-file-names is non-nil. (Bug#13661)
1012 * xdisp.c (decode_mode_spec): Remove handling of %t.
1014 * msdos.c (careadlinkatcwd): Remove.
1016 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1018 * lread.c (skip_dyn_bytes): New function (bug#12598).

1072 if isFullscreen returns YES.
1073 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1074 (check_native_fs): New function.

1092 (syms_of_nsterm): Add ns-use-native-fullscreen.
1094 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1096 * fileio.c (Qchoose_write_coding_system): Now static.
1098 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1100 * xdisp.c (window_buffer_changed): region_showing can be negative,
1101 which still means region is being displayed.
1102 (redisplay_internal): Resurrect code that forced redisplay of the
1103 whole window when showing region and the mark has changed.
1104 Record the new mark position to allow redisplay optimizations.
1105 (display_line): If it->region_beg_charpos is non-zero, set the
1106 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1108 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1109 not bitfield of 1 bit.
1111 2013-02-03 Daniel Colascione <dancol@dancol.org>
1113 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1114 daemon mode works on cygw32 when Emacs is installed and not just
1117 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1119 Avoid file time stamp bug on MS-Windows (Bug#13149).
1120 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1121 as FAT32 doesn't update time stamps when truncating them.
1122 Also, check that a file time stamp is not a multiple of 100 ns;
1123 this should catch all instances of the problem on MS-Windows,
1124 as its native file system resolution is 100 ns or worse, and
1125 checking for a non-multiple of 100 ns should impose only a small
1126 overhead on systems with ns resolution.
1128 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1130 Avoid encoding file names on MS-Windows when they need to be run
1131 through dostounix_filename.
1132 * w32.c (normalize_filename): Accept an additional argument
1133 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1134 downcase it even if w32-downcase-file-names is non-nil.
1135 (dostounix_filename): Accept an additional argument MULTIBYTE and
1136 pass it to normalize_filename.
1137 (emacs_root_dir): Adjust.

1141 * w32.h (dostounix_filename): Adjust prototype.
1143 * msdos.c (dostounix_filename): Accept an additional argument and
1145 (init_environment): Adjust callers of dostounix_filename.
1147 * fileio.c (Ffile_name_directory, file_name_as_directory)
1148 (directory_file_name, Fexpand_file_name)
1149 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1151 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1153 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1154 variables, as egetenv is case-insensitive for DOS_NT.
1156 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1157 with an encoded file name.
1159 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1160 Adjust calls to dostounix_filename.
1162 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1164 * unexw32.c (unexec): Adjust call to dostounix_filename.
1166 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1168 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1171 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1174 * callproc.c (Fcall_process): Make sure program name in PATH and
1175 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1176 is passed to exec/spawnve, which fails unless the file-name
1179 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1180 even if w32-quote-process-args is nil.
1182 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1184 Fix timestamp bug when write-region appends nothing (Bug#13149).
1185 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1186 the file's time stamp doesn't change if Emacs happens to write nothing
1187 to the file, and on a buggy file system this could cause Emacs to
1188 incorrectly infer that the file system doesn't have the bug.
1189 Avoid this problem by inhibiting the inference in this case.
1191 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1193 * window.h (struct window): Convert base_line_number, base_line_pos
1194 and column_number_displayed members from Lisp_Object to ptrdiff_t.

1204 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1205 (try_scrolling, try_cursor_movement, redisplay_window)
1206 (try_window_reusing_current_matrix, try_window_id, display_line)
1207 (display_mode_lines, decode_mode_spec): Adjust users.
1208 * .gdbinit (pwinx): Do not print sequence_number.
1210 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1212 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1213 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1214 * dired.c: Include <fcntl.h>.
1215 (open_directory): New function, which uses open and fdopendir
1216 rather than opendir. DOS_NT platforms still use opendir, though.

1219 (directory_files_internal, Ffile_attributes): Use it.
1220 (file_attributes, file_name_completion_stat): First arg is now fd,
1221 not dir name. All uses changed. Use fstatat rather than lstat +
1223 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1224 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1225 (emacs_readlinkat): New function, with much of the old
1226 Ffile_symlink_p, but with an fd argument for speed.
1227 It uses readlinkat rather than careadlinkatcwd, so that it
1228 need not assume the working directory.
1229 (Ffile_symlink_p): Use it.
1230 * filelock.c (current_lock_owner): Use emacs_readlinkat
1231 rather than emacs_readlink.
1232 * lisp.h (emacs_readlinkat): New decl.
1233 (READLINK_BUFSIZE, emacs_readlink): Remove.
1234 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1235 (emacs_norealloc_allocator, emacs_readlink): Remove.
1236 This stuff is moved to fileio.c.
1237 * w32.c (fstatat, readlinkat): New functions.
1238 (careadlinkat): Don't check that fd == AT_FDCWD.

1251 (sys_close): Zero out the flags for the file descriptor before
1252 closing it. (Bug#13546)
1254 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1255 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1256 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1259 * w32.c (w32_get_long_filename, init_environment, readlink):
1260 Support file names encoded in DBCS codepages.
1261 (readlink): Use the current file-name-coding-system, not the ANSI
1262 codepage, to decode and handle targets of symlinks.
1264 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1266 * w32.c (opendir): Now accepts a 'const char *'.
1268 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>

1280 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1282 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>

1285 debugging code. Adjust comment style here and there.
1286 * insdel.c (insert_1): Remove.
1287 * lisp.h (insert_1): Remove prototype.
1288 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1290 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1292 * w32.c (max_filename_mbslen): New function.
1293 (normalize_filename, readdir): Use it to detect locales where ANSI
1294 encoding of file names uses a double-byte character set (DBCS).
1295 If a DBCS encoding is used, advance by characters using
1296 CharNextExA, instead of incrementing a 'char *' pointer.
1297 Use _mbslwr instead of _strlwr. (Bug#13515)
1299 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial

1338 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1340 * xdisp.c (message2, message2_nolog): Remove functions.
1341 (message3, message3_nolog): Extract nbytes and multibyteness directly
1342 from the string. Change all callers.
1343 (message3_nolog): Don't set message_enable_multibyte since set_message
1344 will reset it anyway.
1345 (message1, message1_nolog): Use message3.
1346 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1347 (with_echo_area_buffer): Remove last two arguments. Update all callers.

1409 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1411 * w32.c (acl_set_file): Don't test for errors unless
1412 set_file_security returns FALSE. Avoids spurious errors when
1415 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1417 * fileio.c (Finsert_file_contents): Revert code introduced at
1418 2013-01-18 in favor of the simpler and generally better fix.
1419 Save stack space by removing 'buffer' and reusing 'read_buf'
1422 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1424 * lisp.h (eabs): Define unconditionally (Bug#13419).
1425 The old "#if !defined (eabs)" was an unnecessary revenant of back
1426 when this macro was called "abs". Document 'eabs' better.
1428 2013-01-19 Glenn Morris <rgm@gnu.org>
1430 * fns.c (Frandom): Doc fix.
1432 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1434 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1435 segfault when there are lots of overlays.
1437 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1438 when there are lots of overlays.
1439 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1440 for the details and a way to reproduce.
1442 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1444 * fileio.c: Use O_APPEND to append.
1445 This corresponds better to the natural interpretation of "append",
1446 and avoids the need to open the output file twice, or to invoke
1447 lseek when APPEND is neither nil nor a number.
1448 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1449 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1450 file possibly twice, and lseeking to its end; this avoids the
1451 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1452 at the same time: the combination is never needed and apparently
1453 it doesn't work with DOS_NT.
1455 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1456 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1458 Allow floating-point file offsets.
1459 Problem reported by Vitalie Spinu in
1460 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1461 * fileio.c (emacs_lseek): Remove.
1462 (file_offset): New function.
1463 (Finsert_file_contents, Fwrite_region): Use it.
1465 2013-01-19 Chong Yidong <cyd@gnu.org>
1467 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1468 aborting on Fsignal (Bug#13289).
1470 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1472 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1473 set_file_security as failure due to insufficient privileges.
1474 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1475 (fstat): Return owner and group like 'stat' and 'lstat' do.
1477 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1479 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1480 The bug was observed on Ubuntu operating inside a virtual machine,
1481 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1482 The workaround introduces a race condition on non-buggy hosts,
1483 but it's an unlikely race and anyway there's a nearly identical
1484 nearby race that can't be fixed.
1485 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1487 (Fwrite_region): Test for file system time stamp bug.
1488 (init_fileio): New function.
1489 * lisp.h (init_fileio): Declare it.
1490 * emacs.c (main): Call it.
1492 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1493 and make it more consistent with other stat-failure diagnostics.
1495 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1497 Fix crash when inserting data from non-regular files.
1498 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1499 for the error description produced by valgrind.
1500 * fileio.c (read_non_regular): Rename to read_contents.
1501 Free Lisp_Save_Value object used to pass parameters.
1502 (read_non_regular_quit): Rename to read_contents_quit.
1503 (Finsert_file_contents): Redesign internal file reading loop to adjust
1504 gap and end positions after each read and so help make_gap to work
1505 properly. Do not signal an I/O error too early and so do not leave
1506 not yet decoded characters in a buffer, which was the reason of
1507 redisplay crash. Use list2 to build return value. Adjust comments.
1509 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1511 Close a race when statting and reading files (Bug#13149).
1512 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1513 This avoids a race if the file is renamed between stat and open.
1514 This race is not the problem originally noted in Bug#13149;
1515 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1517 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

1525 * alloc.c (format_save_value): Rename to make_save_value.
1526 (make_save_pointer): New function.
1527 (record_xmalloc): Use make_save_pointer.
1528 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1529 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1530 Change users of make_save_value to make_save_pointer.
1531 Likewise for format_save_value and make_save_value.

1547 (map_keymap_char_table_item): Adjust accordingly.
1548 * fileio.c (non_regular_fd, non_regular_inserted)
1549 (non_regular_nbytes): Remove.
1550 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1551 Use format_save_value to pass parameters to read_non_regular.
1552 (read_non_regular): Use XSAVE_ macros to extract parameters.
1554 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1556 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1558 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1560 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1561 extraction from any Lisp_Save_Value slot. Add type checking.
1562 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1563 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1564 * xselect.c: All users changed.
1566 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

1577 (save_excursion_restore): Use XSAVE_OBJECT.
1579 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1581 Avoid needless casts with XSAVE_POINTER.
1582 * alloc.c (mark_object) [GC_MARK_STACK]:

1584 * fileio.c (do_auto_save_unwind):
1585 * gtkutil.c (pop_down_dialog):
1586 * keymap.c (map_keymap_char_table_item):
1587 * lread.c (load_unwind):
1588 * nsmenu.m (pop_down_menu):

1598 car and cdr becomes protected with the backtrace entry.
1600 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1602 Make Lisp_Save_Value more versatile storage for up to four objects.

1612 (free_save_value): Likewise.
1613 (mark_object): Likewise.
1614 * editfns.c (save_excursion_save): Pack everything within
1615 Lisp_Save_Value and so avoid xmalloc.
1616 (save_excursion_restore): Adjust to match new layout. Use free_misc
1617 because we do not allocate extra memory any more. Add eassert.
1618 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1619 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

1629 Bug#11484 with LCD smoothing on.
1631 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
1633 Fix SIGDANGER handlers, for AIX (Bug#13408).
1634 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
1635 Move handlers here from emacs.c; they were out of place.

1687 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1689 Avoid unnecessary byte position calculation for the gap movement.
1690 Since all users of move_gap do CHAR_TO_BYTE for other purposes
1691 anyway, all of them should use move_gap_both instead.

1703 * term.c (init_tty): Use them instead of rolling our own code.
1704 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1705 switches from 'signal' to 'pthread_sigmask', which is safer in
1706 multithreaded applications.
1707 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1708 which has already arranged for that.
1709 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.

1722 predicate, which is how it's really used now. Adjust comment.
1723 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1724 * buffer.c (buffer_slot_type_mismatch): Remove.
1725 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

1730 right-fringe-width, scroll-bar-width and buffer-display-count.
1731 Use Qstringp for default-directory, buffer-file-name,
1732 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1733 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1735 * data.c (store_symval_forwarding): Adjust to call the predicate.

1778 trailing dash is properly added.
1780 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1782 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1783 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1784 digits for buffer positions, before misalignment starts.
1785 Display "0" for integer "object" field.
1786 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1787 Display the newline glyph more unambiguously.

1863 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1865 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1866 (LIBS_GNUSTEP): Define.
1867 (LIBES): Add $(LIBS_GNUSTEP).
1868 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1870 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1872 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1873 continuation glyph on a TTY with an indication of an empty line.
1876 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1878 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1879 file's SELinux context or ACLs successfully set, nil otherwise.
1881 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1883 * w32proc.c (reader_thread): Avoid passing NULL handles to
1884 SetEvent and WaitForSingleObject.
1886 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1888 Port EXTERNALLY_VISIBLE to Clang 3.2.
1889 * conf_post.h (__has_attribute): New macro.
1890 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1892 2012-12-27 Glenn Morris <rgm@gnu.org>
1894 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1895 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1897 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1899 * fileio.c (file_name_as_directory, directory_file_name):
1900 Accept an additional argument MULTIBYTE to indicate whether the input C
1901 came from a multibyte or a unibyte Lisp string; all callers
1902 adjusted. Don't assume the input string is always multibyte.
1904 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1905 don't ENCODE_FILE them, and return a unibyte string if the input
1907 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1908 don't assume the input strings will always be multibyte. If the
1909 input strings are multibyte, decode strings obtained from C
1912 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1914 * lisp.h (toplevel): Add two notices to the comment about
1915 defining a new Lisp data type.
1916 * print.c (print_object): If Lisp_Save_Value object's pointer
1917 is the address of a memory area containing Lisp_Objects, try
1919 * alloc.c (valid_lisp_object_p): Adjust comment.
1921 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1923 * keyboard.c (record_asynch_buffer_change): Initialize an event
1924 only if it's really needed.
1925 * frame.h (enum output_method): Remove output_mac member since
1926 it's a leftover from the deleted code.
1927 * frame.c (Fframep): Adjust user here ...
1928 * terminal.c (Fterminal_live_p): ... and here.
1929 * coding.c (Qmac): Now here because it's only used to denote
1930 end-of-line encoding type.
1931 (syms_of_coding): DEFSYM it.
1932 * frame.h (Qmac): Remove duplicated declaration.
1934 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1936 * window.c (select_window_1): Now static, since it's used only here.
1938 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1940 * window.c (window_body_cols): Subtract display margins from the
1941 window body width on TTYs as well. See
1942 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1943 for the original report.
1945 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1947 * xdisp.c (redisplay_window): Remove inner local variable
1948 because the outer shadowed one has the same meaning.
1949 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1951 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1952 (xg_create_tool_bar): Adjust users.
1954 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1956 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1957 * buffer.c (Fget_buffer_create): Use it to set compact field of
1958 struct buffer_text to avoid accessing an uninitialized value
1959 when compact_buffer is called for the first time.
1960 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1961 (Fset_buffer_modified_p): Use buffer_window_count to check
1962 whether the buffer is displayed in some window.
1963 * xdisp.c (message_dolog): Likewise.
1965 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1967 * w32.c (acl_set_file): If setting the file security descriptor
1968 fails, and the new DACL is identical to the existing one, silently
1969 return success. This fixes problems for users backing up their
1970 own files without having the necessary privileges for setting
1971 security descriptors.
1973 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1975 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1976 after WaitForSingleObject returns normally. This expedites reader
1977 thread shutdown when delete_child triggers it.
1978 (reap_subprocess): More accurate commentary for why we call
1979 delete_child only when cp->fd is negative.
1981 * w32.c (sys_close): Do not call delete_child on a subprocess
1982 whose handle is not yet closed. Instead, set its file descriptor
1983 to a negative value, so that reap_subprocess will call
1984 delete_child on that subprocess when its SIGCHLD arrives.
1985 This avoids closing handles used for communications between sys_select
1986 and reader_thread, which doesn't give sys_select a chance to
1987 notice that the process exited and invoke the SIGCHLD handler for
1990 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1992 * nsfns.m (Fns_do_applescript): Run event loop until script has
1993 been executed (Bug#12969).
1994 (ns_run_ascript): Chech as_script for nil, set to nil after
1997 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1999 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2001 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2003 * w32term.c (w32fullscreen_hook): New function.
2004 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2006 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2008 * fileio.c (Finsert_file_contents): Doc fix.
2010 * w32proc.c (new_child, delete_child, find_child_pid): For a
2011 subprocess, consider its slot being in use as long as its process
2012 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2013 slot when a new process is started immediately after killing
2014 another one, without waiting enough time for the first process to
2015 be reaped and resources allocated for it be orderly freed.
2017 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2019 2012-12-21 Chong Yidong <cyd@gnu.org>
2021 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2023 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2025 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2027 * w32.c (get_name_and_id): Always pass NULL as the first argument
2028 of lookup_account_sid. Avoids crashes with UNC file names that
2029 refer to DFS domains, not to specific machine names. (Bug#12621)
2030 Remove now unused argument FNAME; all callers changed.
2031 (get_file_owner_and_group): Remove now unused argument FNAME; all
2034 2012-12-21 Chong Yidong <cyd@gnu.org>
2036 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2037 error for invalid chars, don't check for a nil return value.
2039 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2041 Avoid calls to CHAR_TO_BYTE if byte position is known.
2042 * editfns.c (make_buffer_string_both): Use move_gap_both.
2043 (Fbuffer_string): Use make_buffer_string_both.
2044 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2046 (buf_bytepos_to_charpos): Likewise.
2047 (charpos_to_bytepos): Remove.
2048 * fileio.c (Finsert_file_contents): Use move_gap_both.
2049 * search.c (Freplace_match): Likewise.
2050 * process.c (process_send_region): Likewise. Use convenient
2051 names for byte positions.
2052 * lisp.h (charpos_to_bytepos): Remove prototype.
2053 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2054 * insdel.c (move_gap): Likewise.
2056 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2058 * xdisp.c (redisplay_internal): Remove now-unused local.
2060 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2062 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2063 (redisplay_internal): Don't bother selecting the frame to get the
2064 proper value of frame-local variables (bug#13225).
2066 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2068 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2069 Rename 4th argument since it may be buffer or string. Adjust comment.
2070 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2072 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2074 * coding.c (Fdetect_coding_region): Do not check start and end with
2075 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2076 (code_convert_region): Likewise.
2078 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2080 * w32.c (acl_get_file, acl_set_file): Run the file name through
2081 map_w32_filename, and resolve any symlinks in the file name, like
2083 (acl_set_file): Call revert_to_self, if any privileges were
2086 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2088 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2089 ($(BLD)/w32.$(O)): Update dependencies.
2091 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2093 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2094 propagate redisplay's scrolling (if any) to the right window.
2095 (redisplay_internal): Use ensure_selected_frame.
2096 (display_mode_lines): Complete last fix.
2097 * window.c (select_window_1): New func, extracted from select_window.
2098 (select_window): Use it.
2099 * window.h (select_window_1): Declare.
2101 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2103 Emulate Posix ACL APIs on MS-Windows.
2104 * w32.c: Include sddl.h and sys/acl.h.
2105 (SDDL_REVISION_1): Define if not already defined.
2106 (g_b_init_get_security_descriptor_dacl)
2107 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
2108 (g_b_init_is_valid_security_descriptor)

2121 (acl_free, acl_get_file, acl_set_file): New functions.
2123 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
2125 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2127 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2128 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2129 for some of that bug's symptoms can now cause Emacs to abort.
2130 Remove the workaround.
2131 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2132 The bug that caused SIGCHLD to get lost has been fixed, and the
2133 workaround for it can now cause Emacs to abort.
2135 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2137 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2138 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2139 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
2141 2012-12-16 Romain Francoise <romain@orebokech.com>
2143 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2144 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2145 and copy ACL entries of file in addition to SELinux context if set.
2146 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2148 * Makefile.in (LIBACL_LIBS): New macro.

2161 (record_infile, record_pending_deletion): New prototypes.
2163 * w32proc.c (new_child): Initialize input_file and
2164 pending_deletion members of the child.
2165 (delete_child): Delete the child's temporary input file, if any,
2166 that is pending deletion.
2167 (register_child): First argument is now pid_t.
2168 (record_infile, record_pending_deletion): New functions.
2169 (reap_subprocess): Fix a typo in DebPrint string.
2170 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2172 * fileio.c (internal_delete_file): Return an int again: non-zero
2173 if delete-file succeeds, zero otherwise.
2175 * lisp.h (internal_delete_file): Adjust prototype.
2177 * callproc.c (Fcall_process): Don't overwrite infile with result
2179 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2180 asynchronous subprocess, record the name of the input file name,
2182 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2183 delete the file, record it as pending deletion when the subprocess
2186 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2188 * editfns.c [HAVE_PWD_H]: Include grp.h.
2190 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.

2194 Fix permissions bugs with setgid directories etc. (Bug#13125)
2195 * dired.c (Ffile_attributes): Return t as the 9th attribute,
2196 to mark it as a placeholder. The old value was often wrong.
2197 The only user of this attribute has been changed to use
2198 file-ownership-preserved-p instead, with its new group arg.
2199 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
2201 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

2206 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2208 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2209 try to get accurate owner and group information from NT file
2210 security APIs. This is to make most callers of 'stat' and
2211 'lstat', which don't need that information, much faster.
2213 * dired.c (Ffile_attributes) [WINDOWSNT]:
2214 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2215 owner and group information from 'lstat'.
2217 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2219 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2220 as that confuses set-auto-coding, so insist on the head-read
2221 returning the full 1024 bytes. Let lseek compute the tail offset;
2222 less work for us. Do not ignore I/O errors when reading the tail.
2224 * xdisp.c: Minor style fixes.
2225 (init_iterator): Hoist assignment out of if-expression.
2226 (markpos_of_region): Callers now test for sign, not for -1.
2228 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
2230 Minor redisplay optimization when the region length is zero.
2231 * xdisp.c (markpos_of_region): New function.
2232 (init_iterator): Do not highlight the region of zero length.
2233 (redisplay_window): Check whether the region is of non-zero length.
2234 (try_cursor_movement): Allow if the region length is zero.
2235 (try_window_reusing_current_matrix, try_window_id): Likewise.
2237 2012-12-13 Eli Zaretskii <eliz@gnu.org>
2239 * search.c (search_buffer): Check the inverse translations of each
2240 character in pattern when the buffer being searched is unibyte.
2243 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2245 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2246 files, fixing a regression from 24.2.
2247 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2249 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2251 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2252 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2253 Remove unnecessary S_ISLNK test, as (contra the comments) this
2254 function can't copy symlinks. Improve quality of error message
2255 when attempting to copy files that are neither regular files nor

2262 * window.c (Frecenter):
2263 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
2264 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
2266 2012-12-12 Daniel Colascione <dancol@dancol.org>
2268 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2269 the dumped Emacs is not a sparse file, greatly improving Cygwin
2270 "make bootstrap" performance.
2272 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
2274 * inotify.c (inotify_callback): Generate an Emacs event for every
2275 incoming inotify event.
2277 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2279 * xdisp.c (handle_face_prop): Fix logic of computing
2280 it->start_of_box_run_p.
2281 (append_space_for_newline): If the glyph row is R2L, reset the
2282 iterator's end_of_box_run_p flag before prepending the space glyph.
2283 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2284 iterator's start_of_box_run_p flag before prepending the stretch.
2285 (append_glyph, produce_image_glyph, append_composite_glyph)
2286 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2287 left_box_line_p and right_box_line_p flags of the glyph for R2L
2288 glyph rows. (Bug#13011)
2290 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2292 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
2293 if changed buffer is not shown in a window.
2294 * insdel.c (prepare_to_modify_buffer): Likewise.
2295 * window.c (replace_buffer_in_windows_safely): Do nothing
2296 if buffer is not shown in a window.
2297 (Fforce_window_update): Likewise if string or buffer argument
2300 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2302 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
2303 encoded_file_name, which is what it is.
2305 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2307 Consistently use marker_position and marker_byte_position.
2308 * fringe.c (Ffringe_bitmaps_at_pos):
2309 * indent.c (Fvertical_motion):
2310 * insdel.c (prepare_to_modify_buffer):

2315 * xdisp.c (message_dolog, with_echo_area_buffer_unwind_data)
2316 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
2317 Replace direct access to marker fields with calls
2318 to marker_position and/or marker_byte_position.
2320 2012-12-11 Juanma Barranquero <lekktu@gmail.com>
2322 * makefile.w32-in (SIG2STR_H): New macro.
2323 (SYSWAIT_H, $(BLD)/emacs.$(O), $(BLD)/process.$(O))
2324 ($(BLD)/w32notify.$(O)): Update dependencies.
2326 2012-12-10 Daniel Colascione <dancol@dancol.org>

2329 Windows file notification functionality unless WINDOWSNT.
2331 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
2334 * w32fns.c (cache_system_info): Initialize the global hinst
2335 variable here so various initialization calls DTRT.
2337 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
2338 (hinst): Remove unneeded extern declaration.
2339 (_start): Remove initialization of above variables; remove

2451 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
2453 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
2454 DWORD_PTR, for compatibility with 64-bit builds.

2482 * w32.c (unsetenv): Return 0 if the input string is too long.
2484 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2486 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).

2488 * dbusbind.c (Fdbus_init_bus):
2490 * xterm.c (x_term_init):

2501 no longer needed here.
2502 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
2503 Move to inside set_time_zone_rule; they don't need file scope any more.
2504 (set_time_zone_rule): Maintain the TZ=value string separately.
2505 (syms_of_editfns): Don't initialize initial_tz;
2506 init_editfns now does it.
2507 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
2508 * lisp.h (xputenv): New decl.
2510 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
2512 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
2514 2012-12-08 Eli Zaretskii <eliz@gnu.org>
2516 * w32.c (unsetenv, sys_putenv): New functions.

2521 informative (Bug#12992).
2523 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2525 Simplify get_lim_data.
2526 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2527 Remove USG and vlimit methods; no longer used these days.
2528 Add #error catchall just in case.
2530 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2531 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2532 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
2533 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
2534 (deleted_pid_list, Fdelete_process, create_process)
2535 (record_child_status_change, handle_child_signal, deliver_child_signal)

2539 (abbr_to_signal): New static function.
2540 (Fsignal_process): Use it to convert signal names to ints.

2549 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
2551 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
2553 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
2554 This will cause a production Emacs to dump core instead of
2557 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2559 * frame.c (make_frame): Do not set window's buffer to t.
2560 * window.c (Fsplit_window_internal): Likewise. Previously it was
2561 used to indicate that the window is being set up. Now we use
2562 set_window_buffer for all new windows, so the condition in ...
2563 (Fset_window_buffer): ... is always true and can be removed.
2565 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2567 Convenient macro to check whether the buffer is hidden.
2568 * buffer.h (BUFFER_HIDDEN_P): New macro.
2569 * frame.c (make_frame): Use it. Adjust comment.
2570 * buffer.c (candidate_buffer): New function.
2571 (Fother_buffer, other_buffer_safely): Use it.
2573 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2575 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2576 if the child process is still running. Instead, exit the wait
2577 loop and return zero. (Bug#13086)
2579 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2581 * frame.h (x_char_width, x_char_height): Remove prototypes.

2595 * callproc.c, process.h (record_kill_process):
2596 New function, containing part of the old call_process_kill.
2597 (call_process_kill): Use it.
2598 This does not change call_process_kill's behavior.
2599 * process.c (Fdelete_process): Use record_kill_process to fix a
2600 race condition that could cause Emacs to lose track of a child.
2602 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2604 Avoid code duplication between prev_frame and next_frame.
2605 * frame.c (candidate_frame): New function. Add comment.
2606 (prev_frame, next_frame): Use it. Adjust comment.
2608 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2610 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2611 fails, signal an error instead of continuing with an empty
2613 Encode expanded temp file pattern before passing it to mkstemp or
2616 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2617 Encode the file name before passing it to dostounix_filename, in
2618 case it will downcase it (under w32-downcase-file-names).
2621 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2623 Minor call-process cleanups.
2624 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2625 at the same time as other platforms, to simplify analysis.
2626 No need for fd0_volatile since we have synch_process_fd.
2627 Avoid needless emacs_close; arg is always negative.
2629 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2631 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2634 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2636 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2637 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2638 and mouse_face_hidden members to a bitfields.

2642 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2643 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2644 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2645 members to a bitfields.
2647 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2649 Don't let call-process be a zombie factory (Bug#12980).
2650 Fixing this bug required some cleanup of the signal-handling code.
2651 As a side effect, this change also fixes a longstanding rare race
2652 condition whereby Emacs could mistakenly kill unrelated processes,
2653 and it fixes a bug where a second C-g does not kill a recalcitrant
2654 synchronous process in GNU/Linux and similar platforms.
2655 The patch should also fix the last vestiges of Bug#9488,
2656 a bug which has mostly been fixed on the trunk by other changes.
2657 * callproc.c, process.h (synch_process_alive, synch_process_death)
2658 (synch_process_termsig, sync_process_retcode):
2659 Remove. All uses removed, to simplify analysis and so that
2660 less consing is done inside critical sections.
2661 * callproc.c (call_process_exited): Remove. All uses replaced
2662 with !synch_process_pid.
2663 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2664 These take the role of what used to be in unwind-protect arg.
2666 (block_child_signal, unblock_child_signal):
2667 New functions, to avoid races that could kill innocent-victim processes.
2668 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2669 (call_process_kill): Record killed processes as deleted, so that
2670 zombies do not clutter up the system. Do this inside a critical
2671 section, to avoid a race that would allow the clutter.
2672 (call_process_cleanup): Fix code so that the second C-g works again
2673 on common platforms such as GNU/Linux.
2674 (Fcall_process): Create the child process in a critical section,
2675 to fix a race condition. If creating an asynchronous process,
2676 record it as deleted so that zombies do not clutter up the system.
2677 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2678 light of these changes. Omit unnecessary call to emacs_close
2679 before failure, as the unwind-protect code does that.
2680 * callproc.c (call_process_cleanup):
2681 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2682 * process.c (record_deleted_pid): New function, containing
2683 code refactored out of Fdelete_process.
2684 (Fdelete_process): Use it.
2685 (process_status_retrieved): Remove. All callers changed to use
2686 child_status_change.
2687 (record_child_status_change): Remove, folding its contents into ...
2688 (handle_child_signal): ... this signal handler. Now, this
2689 function is purely a handler for SIGCHLD, and is not called after
2690 a synchronous waitpid returns; the synchronous code is moved to
2691 wait_for_termination. There is no need to worry about reaping
2692 more than one child now.
2693 * sysdep.c (get_child_status, child_status_changed): New functions.
2694 (wait_for_termination): Now takes int * status and bool
2695 interruptible arguments, too. Do not record child status change;
2696 that's now the caller's responsibility. All callers changed.
2697 Reimplement in terms of get_child_status.
2698 (wait_for_termination_1, interruptible_wait_for_termination):
2699 Remove. All callers changed to use wait_for_termination.
2700 * syswait.h: Include <stdbool.h>, for bool.
2701 (record_child_status_change, interruptible_wait_for_termination):
2703 (record_deleted_pid, child_status_changed): New decls.
2704 (wait_for_termination): Adjust to API changes noted above.
2706 * bytecode.c, lisp.h (Qbytecode): Remove.
2707 No longer needed after 2012-11-20 interactive-p changes.
2709 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2711 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2712 the scroll margin, move point outside the margin. (Bug#13055)
2714 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2716 * gtkutil.c (my_log_handler): New function.
2717 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2719 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2721 * lisp.h (modify_region): Rename to...
2722 (modify_region_1): ...new prototype.
2723 * textprop.c (modify_region): Now static. Adjust users.
2724 * insdel.c (modify_region): Rename to...
2725 (modify_region_1): ...new function to work with current buffer.
2726 Adjust comment and users. Use true and false for booleans.
2728 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2730 * alloc.c (free_save_value): New function.
2731 (safe_alloca_unwind): Use it.
2732 * lisp.h (free_save_value): New prototype.
2733 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2735 (save_excursion_restore): Adjust to match saved data structure.
2736 Use free_save_value to offload some work from GC. Drop obsolete
2739 2012-12-03 Chong Yidong <cyd@gnu.org>
2741 * fileio.c (Vauto_save_list_file_name): Doc fix.
2743 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2745 * w32fns.c: Remove prototype of atof.
2746 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2748 (file_dialog_callback): Make it UINT_PTR.
2750 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2753 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2754 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2757 2012-12-03 Glenn Morris <rgm@gnu.org>
2759 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2761 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2763 Fix xpalloc confusion after memory is exhausted.
2764 * alloc.c (xpalloc): Comment fix.
2765 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2766 and signals an error, do not clear charset_table_size, as
2767 charset_table is still valid.
2768 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2770 Use execve to avoid need to munge environ (Bug#13054).
2771 * callproc.c (Fcall_process):
2772 * process.c (create_process):
2773 Don't save and restore environ; no longer needed.
2774 * callproc.c (child_setup):
2775 Use execve, not execvp, to preserve environ.
2777 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2779 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).

2791 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2793 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2795 * xdisp.c (window_outdated): Remove eassert since it hits
2796 some suspicious corner cases (see Bug#13007 and Bug#13012).

2810 * callproc.c (Fcall_process): Fix vfork portability problems.
2811 Do not assume that fd[0], count, filefd, and save_environ survive
2812 vfork. Fix bug whereby wrong errno value could be reported for
2813 pipe failure. Some minor cleanups, too, as follows. Move buf and
2814 bufsize to the context where they're needed. Change new_argv to
2815 be of type char **, as this is more convenient and avoids casts.
2816 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2817 Now local constants, not macros.
2819 2012-11-18 Kenichi Handa <handa@gnu.org>
2821 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2822 for the variable "f".
2824 2012-11-13 Kenichi Handa <handa@gnu.org>
2826 * font.c (font_unparse_xlfd): Exclude special characters from the
2827 generating XLFD name.
2829 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
2831 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
2832 * dired.c (stat_uname, stat_gname):
2833 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
2835 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

2839 * fileio.c (Fcopy_file): Assume EISDIR is defined.
2840 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
2841 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
2842 * lread.c (readbyte_from_file): Assume EINTR is defined.
2843 * process.c (wait_reading_process_output, send_process) [subprocesses]:
2844 Assume EIO and EAGAIN are defined.
2845 * unexcoff.c (write_segment): Assume EFAULT is defined.
2847 2012-11-27 Eli Zaretskii <eliz@gnu.org>
2849 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
2852 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2853 highlighting on the frame was cleared. Prevents assertion
2854 violations when repeatedly clicking on the "Top" link of the
2855 "bread-crumbs" in Info buffers.
2857 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
2859 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
2861 2012-11-24 Ken Brown <kbrown@cornell.edu>
2863 * keyboard.c (HAVE_MOUSE):
2864 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2865 were always defined.
2867 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2869 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2870 between bpos_covered and bpos_max. This fixes cursor display when
2871 several display strings follow each other.
2873 * .gdbinit (pgx): If the glyph's object is a string, display the
2874 pointer to string data, rather than the value of the string object
2875 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2877 * indent.c (Fvertical_motion): If the starting position is covered
2878 by a display string, return to one position before that, to avoid
2879 overshooting it inside move_it_to. (Bug#12930)
2881 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2883 * frame.h (struct frame): Remove display_preempted member
2884 since all users are dead long ago.
2885 * nsterm.h (struct x_output): Use the only dummy member.
2886 * w32menu.c (pending_menu_activation): Remove since not
2888 (set_frame_menubar): Adjust user.
2889 * w32term.h (struct x_output): Drop outdated #if 0 code.
2890 (struct w32_output): Use bitfields for explicit_parent,
2891 asked_for_visible and menubar_active members.
2892 Drop unused pending_menu_activation member.
2893 * xterm.h (struct x_output): Drop outdated #if 0 code.
2894 Use bitfields for explicit_parent, asked_for_visible,
2895 has_been_visible and net_wm_state_hidden_seen members.
2897 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2899 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2900 of a literal "/". (Bug#12955)
2901 (gl-stamp): Invoke fc.exe directly, not through cmd.
2903 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
2905 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2906 * dired.c: Assume HAVE_DIRENT_H.
2907 (NAMLEN): Remove, replacing with ...
2908 (dirent_namelen): New function. All uses changed. Use the GNU macro
2909 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2910 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2911 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2912 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2914 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2915 * ndir.h: Rename to ../nt/inc/dirent.h.
2916 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2917 Do not include <dirent.h>; no longer needed.
2918 * w32.c: Include <dirent.h> rather than "ndir.h".
2920 2012-11-23 Chong Yidong <cyd@gnu.org>
2922 * xftfont.c (xftfont_open): Remove duplicate assignment.
2924 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2926 * alloc.c (Fgarbage_collect): Unblock input after clearing
2927 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2928 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2929 * msdos.c (IT_frame_up_to_date): Use it here...
2930 * w32term.c (w32_frame_up_to_date): ...here...
2931 * xterm.c (XTframe_up_to_date): ...and here...
2932 * nsterm.m (ns_frame_up_to_date): ...but not here.
2933 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2935 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2936 Do not check whether GC is in progress.
2938 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2940 * xdisp.c (window_buffer_changed): New function.
2941 (update_menu_bar, update_tool_bar): Use it to
2942 simplify large 'if' statements.
2943 (redisplay_internal): Generalize commonly used
2944 'tail' and 'frame' local variables.
2946 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2948 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2949 with Windows system header.
2951 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2953 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2954 * alloc.c: Assume unistd.h exists.
2955 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
2956 * sysdep.c (get_current_dir_name): Assume getcwd exists.
2957 (getwd) [USG]: Remove; no longer needed.
2958 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2959 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2960 * w32.h (getcwd): Remove decl.
2962 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2964 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2965 Make it set selected_window as well.
2966 (update_tool_bar): Use it.
2968 2012-11-21 Ken Brown <kbrown@cornell.edu>
2970 * emacs.c (main): Set the G_SLICE environment variable for all
2971 Cygwin builds, not just GTK builds. See
2972 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2974 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2976 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2977 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2978 Define for the MSVC compiler.
2980 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2982 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2983 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2984 dostounix_filename. Prevents crashes down the road, because
2985 dostounix_filename assumes it gets a unibyte string.
2986 Reported by Michel de Ruiter <michel@sentient.nl>, see
2987 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
2989 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

2993 * lread.c (init_obarray): Set `function' fields to Qnil.
2994 * eval.c (Fcommandp): Ignore Qunbound.
2995 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2996 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2997 Test NILP rather than Qunbound.
2998 (Ffmakunbound): Set to Qnil.
2999 (Fsymbol_function): Never signal an error.
3000 (Finteractive_form): Ignore Qunbound.
3002 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3004 * eval.c (interactive_p): Remove no-longer-used decl.
3006 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3008 * xdisp.c (buffer_shared): Adjust comment.
3009 (buffer_shared_and_changed): New function.
3010 (prepare_menu_bars, redisplay_internal): Use it to
3011 decide whether all windows or frames should be updated.
3012 (window_outdated): New function.
3013 (text_outside_line_unchanged_p, redisplay_window): Use it.
3014 (redisplay_internal): Likewise. Fix indentation.
3016 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3018 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3019 (syms_of_eval): Remove corresponding defsubr.
3020 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3022 2012-11-19 Daniel Colascione <dancol@dancol.org>
3024 * w32fns.c (Fx_file_dialog):
3025 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3026 cygwin_convert_file_name*.
3028 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3029 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3031 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3033 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3035 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3037 * w32select.c: Include w32common.h before w32term.h, so that
3038 windows.h gets included before w32term.h uses some of its
3039 features, see below.
3041 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3043 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3045 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3047 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3049 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3050 (ns_select): Return at once if events are held (Bug#12834).
3052 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3054 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3055 Needed following 2012-10-20 change. (Bug#12902)
3057 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3059 * w32proc.c (waitpid): Remove unused label get_result.
3061 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3063 * makefile.w32-in (SYSWAIT_H): New macro.
3064 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3065 ($(BLD)/sysdep.$(O)): Update dependencies.
3067 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3069 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3070 * callproc.c (relocate_fd): Assume F_DUPFD.
3071 * emacs.c, term.c (O_RDWR): Remove.
3072 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3073 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3074 * nsterm.m: Assume <fcntl.h> exists.
3075 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3076 (create_pty, Fmake_network_process, server_accept_connection)
3077 (wait_reading_process_output, init_process_emacs):
3079 (wait_reading_process_output): Put in a special case for WINDOWSNT
3080 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3081 It's not clear this is needed, but it's a more-conservative change.
3082 (create_process): Assume FD_CLOEXEC.
3083 (create_process, create_pty): Assume O_NOCTTY.
3084 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3085 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3086 Omit if not DOS_NT, since F_GETFL is not defined there.
3087 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3088 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3090 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3091 lack it, since gnulib guarantees this.
3092 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3094 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3096 * w32.c (faccessat): Pretend that directories have the execute bit
3097 set. Emacs expects that, e.g., in files.el:cd-absolute.
3099 * w32proc.c (create_child): Don't clip the PID of the child
3100 process to fit into an Emacs integer, as this is no longer a
3102 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3103 reaping only the process specified by PID argument, if that is
3104 positive. Use PID instead of dead_child to know which process to
3105 reap. Wait for the child to die only if WNOHANG is not in
3107 (sys_select): Don't set dead_child.
3109 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3110 as it is no longer needed.
3112 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3114 (record_child_status_change): Remove the setting of
3115 record_at_most_one_child for the !WNOHANG case.
3117 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3119 Fix problems in ns port found by static checking.
3120 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3121 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3122 not to process group.
3123 (ns_select): Use emacs_write, not write, as that's more robust
3124 in the presence of signals.
3125 (fd_handler:): Check for read errors.
3127 2012-11-16 Glenn Morris <rgm@gnu.org>
3129 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3131 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3133 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3135 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3137 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3138 use the same value of thread handle.
3139 (start_timer_thread): If the timer thread exited (due to error),
3140 clean up by closing the two handles it used. Duplicate the caller
3141 thread's handle here, so it gets duplicated only once, when
3142 launching the timer thread. Set priority of the timer thread, not
3144 (getitimer): Don't duplicate the caller thread's handle here.
3147 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3149 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3152 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3154 Remove no-longer-used pty_max_bytes variable.
3155 * process.c (pty_max_bytes): Remove; unused.
3156 (send_process): Do not set it.
3158 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3160 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3161 Update dependencies.
3163 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3165 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3166 This follows up on the 2012-09-29 patch that removed indirection
3167 for the 'function' field. Reported by Sergey Vinokurov in
3168 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3170 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3172 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3173 different name, as the MS runtime does not have such a function,
3174 and probably never will.) All callers changed. Ignore DIRFD
3175 value if PATH is an absolute file name, to match Posix spec
3176 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3179 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3181 * xdisp.c (echo_area_display, redisplay_internal):
3182 Omit redundant check whether frame_garbaged is set.
3184 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3186 Use faccessat, not access, when checking file permissions (Bug#12632).
3187 This fixes a bug that has been present in Emacs since its creation.
3188 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3189 which must set some sort of record. (Torek's bug report was against
3190 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3191 same common flaw.) See Torek's Usenet posting
3192 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3193 Posted: Fri Apr 8 14:18:56 1983.
3194 * Makefile.in (LIB_EACCESS): New macro.
3196 * callproc.c (init_callproc):
3197 * charset.c (init_charset):
3198 * fileio.c (check_existing, check_executable, check_writable)
3200 * lread.c (openp, load_path_check):
3201 * process.c (allocate_pty):
3203 Use effective UID when checking permissions, not real UID.
3204 * callproc.c (init_callproc):
3205 * charset.c (init_charset):
3206 * lread.c (load_path_check, init_lread):
3207 Test whether directories are accessible, not merely whether they exist.
3208 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3209 * fileio.c (check_existing, check_executable, check_writable)
3211 Use symbolic names instead of integers for the flags, as they're
3213 (check_writable): New arg AMODE. All uses changed.
3214 Set errno on failure.
3215 (Ffile_readable_p): Use faccessat, not stat + open + close.
3216 (Ffile_writable_p): No need to call check_existing + check_writable.
3217 Just call check_writable and then look at errno. This saves a syscall.
3218 dir should never be nil; replace an unnecessary runtime check
3219 with an eassert. When checking the parent directory of a nonexistent
3220 file, check that the directory is searchable as well as writable, as
3221 we can't create files in unsearchable directories.
3222 (file_directory_p): New function, which uses 'stat' on most platforms
3223 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3224 (Ffile_directory_p, Fset_file_times): Use it.
3225 (file_accessible_directory_p): New function, which uses a single
3226 syscall for efficiency.
3227 (Ffile_accessible_directory_p): Use it.
3228 * xrdb.c (file_p): Use file_directory_p.
3229 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3230 * lread.c (openp): When opening a file, use fstat rather than
3231 stat, as that avoids a permissions race. When not opening a file,
3232 use file_directory_p rather than stat.
3233 (dir_warning): First arg is now a usage string, not a format.
3234 Use errno. All uses changed.
3235 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3236 that merely introduced a race.
3237 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3238 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3239 and similarly for the other O_* flags.
3240 * w32.c (sys_faccessat): Rename from sys_access and switch to
3241 faccessat's API. All uses changed.
3242 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3243 (magic_db): Rename from magic_file_p.
3244 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3245 char *, so that we don't have to test for file existence
3246 separately from opening the file for reading. This removes a race
3247 fixes a permission-checking problem, and simplifies the code.
3249 (file_p): Remove; no longer needed.
3251 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3253 Omit glyphs initialization at startup.
3254 * dispnew.c (glyphs_initialized_initially_p): Remove.
3255 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3256 (Fredraw_frame): Move actual code from here...
3257 (redraw_frame): ...to here. Add eassert. Adjust comment.
3258 (Fredraw_display): Use redraw_frame.
3259 * xdisp.c (clear_garbaged_frames): Likewise.
3261 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3263 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3264 passed to pint2str and pint2hrstr to be at most the size of the
3265 frame's decode_mode_spec_buffer. This avoids crashes with very
3266 large values of FIELD_WIDTH argument to decode_mode_spec.
3269 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3271 Fix a race with verify-visited-file-modtime (Bug#12863).
3272 Since at least 1991 Emacs has ignored an mtime difference of no
3273 more than one second, but my guess is that this was to work around
3274 file system bugs that were fixed long ago. Since the race is
3275 causing problems now, let's remove that code.
3276 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3277 whose time stamp is off by no more than a second. Insist that the
3278 file time stamps match exactly.
3280 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3282 * frame.h (struct frame): Convert external_tool_bar member to
3283 1-bit unsigned bitfield.

3285 all users are long dead. Adjust comment on mouse_position_hook.
3287 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>

3298 * xmenu.c (menubar_id_to_frame): Likewise.
3299 * xselect.c (frame_for_x_selection): Likewise.
3300 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3301 (x_window_to_menu_bar): Likewise.
3302 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3304 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3306 * data.c (Qdefalias_fset_function): Now static.
3308 Another tweak to vectorlike_header change.
3309 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3310 Remove, and replace all uses with ...
3311 (next_in_free_list, set_next_in_free_list):
3312 New functions, which respect C's aliasing rules better.
3314 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3316 * window.c (list4i): Rename from 'quad'. All uses changed.
3317 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3319 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3321 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3322 warning about mixing declarations and code in ISO C90.
3324 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3326 * window.c (Fsplit_window_internal): Set combination limit of
3327 new parent window to t iff Vwindow_combination_limit is t;
3328 fixing a regression introduced with the change from 2012-09-22.
3329 (Fset_window_combination_limit): Fix doc-string.
3331 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3333 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3334 amount when the scroll margins are too large. When scrolling
3335 backwards in the buffer, give up if cannot reach point or the
3336 scroll margin within a reasonable number of screen lines.
3337 Fixes point position in window under scroll-up/down-aggressively when
3338 point is positioned many lines beyond the window top/bottom.
3341 * ralloc.c (relinquish): If real_morecore fails to return memory
3342 to the system, don't crash; instead, leave the last heap
3343 unchanged and return. (Bug#12774)
3345 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3347 * lisp.h (AUTOLOADP): New macro.

3352 (Finteractive_form): Simplify.
3353 (Fquo): Don't insist on having at least 2 arguments.
3354 (Qdefalias_fset_function): New var.
3356 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3358 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
3360 * nsfont.m (Qcondensed, Qexpanded): New variables.
3361 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
3362 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3364 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3366 Fix recently introduced crash on MS-Windows (Bug#12839).
3367 * w32term.h (struct scroll_bar): Use convenient header.
3368 (SCROLL_BAR_VEC_SIZE): Remove.
3369 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3371 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3373 Tweak last vectorlike_header change.
3374 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3375 vectorlike object on the free list. This is introduced to avoid
3376 some (but not all) pointer casting and aliasing problems, see
3377 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3378 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

3382 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3384 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3385 been removed, so remove them here also.
3387 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3389 * doc.c (Fdocumentation): Handle new property
3390 dynamic-docstring-function to replace the old ad-advice-info.
3392 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3394 * fns.c (Qeql, hashtest_eq): Now static.
3396 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3398 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3399 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3400 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

3403 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
3405 Use same hash function for hashfn_profiler as for hash_string etc.
3406 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3407 * lisp.h (sxhash_combine): New inline function, with the contents
3408 of the old SXHASH_COMBINE.
3409 * profiler.c (hashfn_profiler): Use it, instead of having a
3410 special hash function containing a comparison that always yields 1.
3412 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3414 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3415 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3416 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3419 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3421 * image.c (xpm_make_color_table_h): Fix compiler error because
3422 make_hash_table changed.
3424 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3426 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3428 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3430 Use ad-hoc comparison function for the profiler's hash-tables.
3431 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3432 (make_log): Use them.
3433 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3434 call Fequal any more.
3435 (Ffunction_equal): New function.
3436 (cmpfn_profiler, hashfn_profiler): New functions.

3443 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3444 (hash_lookup, hash_remove_from_table): Move assertion checking of
3445 hashfn result here. Check hash-equality before calling cmpfn.

3447 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
3448 (syms_of_fns): Initialize them.

3457 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3458 value of w32-scroll-lock-modifier is neither nil nor one of the
3459 known key modifiers. (Bug#12806)
3461 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3463 Shrink struct vectorlike_header to the only size field.
3464 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3466 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3467 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3468 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3469 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3470 information from the vector header. Adjust comment.

3482 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3483 (Fmake_bool_vector): Likewise.
3484 (struct large_vector): New type to represent allocation unit for
3485 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3486 (large_vectors): Change type to struct large_vector.
3487 (allocate_vector_from_block): Simplify.
3488 (PSEUDOVECTOR_NBYTES): Replace with...
3489 (vector_nbytes): ...new function. Adjust users.
3490 (sweep_vectors): Adjust processing of large vectors.
3491 (allocate_vectorlike): Likewise.
3492 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3493 Add easserts. Adjust XSETPVECTYPESIZE usage.
3494 (allocate_buffer): Use BUFFER_PVEC_INIT.
3495 (live_vector_p): Adjust to match large vector.
3496 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3497 * buffer.h (struct buffer): Add next member.
3498 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3500 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

3506 (xvecsize): New command.
3508 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3510 * keyboard.c (event_to_kboard): Do not dereference
3511 frame_or_window field of SELECTION_REQUEST_EVENT
3512 and SELECTION_CLEAR_EVENT events (Bug#12814).
3513 * xterm.h (struct selection_input_event): Adjust comment.
3515 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3517 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3518 such as Scroll Lock, if the respective keys are treated as
3519 function keys, not as modifiers. This avoids destroying non-ASCII
3520 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3522 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3524 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3526 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3528 Restore some duplicate definitions (Bug#12814).
3529 This undoes part of the 2012-11-03 changes. Some people build
3530 with plain -g rather than with -g3, and they need the duplicate
3531 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3532 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3533 Define as macros, as well as as enums or as constants.
3535 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3537 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3538 to keypad keys (Bug#12816).
3540 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3542 Minor adjustments of recently-changed frame functions.
3543 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3544 known to be a frame (we're in the FRAMEP branch).
3545 * lisp.h (Qframep): Remove decl. frame.h declares this.
3546 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3547 since they're meant for Lisp fixnum values.
3549 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3551 * window.c (Fwindow_combination_limit): Revert to the only
3552 required argument and adjust docstring as suggested in
3553 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3554 by Martin Rudalics <rudalics@gmx.at>.
3556 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>

3570 (frame_buffer_list, frame_buffer_predicate): Remove.
3571 * lisp.h (frame_buffer_predicate): Remove prototype.
3572 * buffer.c (Fother_buffer): Use decode_any_frame.
3573 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3574 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3575 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3576 (Fclose_font, Ffont_info): Use decode_live_frame.
3577 * fontset.c (check_fontset_name): Likewise.
3578 * terminal.c (Fframe_terminal): Likewise.
3579 * w32fns.c (check_x_frame): Likewise.
3580 * window.c (Fminibuffer_window, Fwindow_at)
3581 (Fcurrent_window_configuration): Likewise.
3582 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3583 Likewise. Allow zero number of arguments. Adjust docstring.
3584 * dispnew.c (Fredraw_frame): Likewise.
3585 * xfaces.c (frame_or_selected_frame): Remove.
3586 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3587 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3588 (Fframe_face_alist): Use decode_live_frame.
3589 * xfns.c (check_x_frame): Likewise.
3591 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3593 * window.c (quad): New function.
3594 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3595 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3596 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3597 (Fwindow_line_height): Use it.
3598 (Fwindow_fringes): Use list3.
3599 (Fwindow_scroll_bars): Use list4.
3600 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3601 (Fwindow_combination_limit): Allow zero number of arguments.
3603 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3605 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3607 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3608 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3609 file descriptor 2 for standard error. (Bug#12805)
3611 2012-11-05 Chong Yidong <cyd@gnu.org>
3613 * process.c (wait_reading_process_output): Revert previous change.
3615 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3617 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3618 This removes code that has been obsolete since around 1990.
3619 * callproc.c (Fcall_process):
3621 * process.c (create_process):
3622 * term.c (dissociate_if_controlling_tty):
3623 Assume setsid exists.
3624 * callproc.c (child_setup): Assume setpgid exists and behaves as
3625 per POSIX.1-1988 or later.
3626 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3627 * emacs.c (shut_down_emacs):
3628 * sysdep.c (sys_suspend, init_foreground_group):
3629 Assume getpgrp behaves as per POSIX.1-1998 or later.
3630 * msdos.c (setpgrp): Remove.
3631 (tcgetpgrp, setpgid, setsid): New functions.
3632 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3633 * term.c (no_controlling_tty): Remove; unused.
3634 * w32proc.c (setpgrp): Remove.
3635 (setsid, tcgetpgrp): New functions.
3637 Simplify by assuming __fpending.
3638 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3639 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3640 Do not assume that __fpending's result fits in int.
3642 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3644 Remove EMACS_OUTQSIZE+sleep hack.
3645 * dispnew.c (update_frame_1): Remove hack for terminals slower
3646 than 2400 bps, which throttled Emacs by having it sleep.
3647 This code hasn't worked since at least 2007, when the multi-tty stuff
3648 was added, and anyway those old terminals are long dead.
3649 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3650 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3652 Fix data-loss with --version (Bug#9574).
3653 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3654 as we can't assume that emacs_strerror is initialized, and strerror
3655 is good enough here.
3656 (main): Invoke atexit earlier, to catch earlier instances of
3657 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3659 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3661 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3662 (keyDown): Remap keypad keys to X11 virtual key codes.
3664 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3666 Fix data-loss with --batch (Bug#9574).
3667 * emacs.c: Include <close-stream.h>.
3668 (close_output_streams): New function.
3669 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3670 and handles errors appropriately.
3671 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3674 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3675 The symptom is a diagnostic "GLib-WARNING **: In call to
3676 g_spawn_sync(), exit status of a child process was requested but
3677 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3678 waitpid(), so exit status can't be returned." The diagnostic
3679 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3680 The real bug is a race condition between Emacs and glib: Emacs
3681 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3682 so that glib can't find it. Work around the bug by invoking
3683 waitpid only on subprocesses that Emacs itself creates.
3684 * process.c (create_process, record_child_status_change):
3685 Don't use special value -1 in pid field, as the caller now must
3686 know the pid rather than having the callee infer it.
3687 The inference was sometimes incorrect anyway, due to another race.
3688 (create_process): Set new 'alive' member if child is created.
3689 (process_status_retrieved): New function.
3690 (record_child_status_change): Use it.
3691 Accept negative 1st argument, which means to wait for the
3692 processes that Emacs already knows about. Move special-case code
3693 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3694 processes that have already been waited for, by testing and
3695 clearing new 'alive' member.
3696 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3697 now does this internally.
3698 (handle_child_signal): Let record_child_status_change do all
3699 the work, since we do not want to reap all exited child processes,
3700 only the child processes that Emacs itself created.
3701 * process.h (Lisp_Process): New boolean member 'alive'.
3703 Omit duplicate definitions no longer needed with gcc -g3.
3704 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3705 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3706 Define only as macros. There's no longer any need to also define
3707 these symbols as enums or as constants, since we now assume
3708 gcc -g3 when debugging.
3710 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3712 * lisp.mk: Adjust comments to the fact that term/internal is now
3713 loaded from loadup.el.
3715 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3716 (msdos_fatal_signal): New function.

3721 for GCC versions before 4.
3722 (emacs_raise): Define to call msdos_fatal_signal.
3724 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3725 iterator when starting in the middle of a display or overlay
3728 2012-11-03 Chong Yidong <cyd@gnu.org>

3735 * process.c (wait_reading_process_output): Avoid a race condition
3736 with SIGIO delivery (Bug#11536).
3738 2012-11-03 Chong Yidong <cyd@gnu.org>
3740 * buffer.c (cursor_type): Untabify docstring.
3742 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3744 * frame.h (struct frame): Drop can_have_scroll_bars member
3745 which is meaningless for a long time. Adjust comments.
3746 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3747 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3749 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3751 * window.c (decode_next_window_args): Update window arg after

3753 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3754 by Juanma Barranquero <lekktu@gmail.com>.
3755 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3756 * font.c (Ffont_at): Likewise.
3758 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>

3769 (BACKTRACE_LIMIT_MAX): New macro.
3770 (w32_backtrace): New function.
3771 (emacs_abort): Use w32_backtrace when the user chooses not to
3772 attach a debugger. Update the text of the abort dialog.
3774 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3776 Window-related stuff cleanup here and there.
3777 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3778 Use decode_any_window.
3779 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3780 * xdisp.c (Fformat_mode_line): Likewise.
3781 * font.c (Ffont_at): Use decode_live_window.

3785 * window.h (decode_any_window): Add prototype.
3786 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3787 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3790 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3792 Remove pad from struct input_event.
3793 * termhooks.h (struct input_event): Remove padding field.
3795 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3796 member is never cons for a long time. Adjust comment.
3797 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3798 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3799 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3800 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3802 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3804 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3806 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3808 Fix crash when using Emacs as commit editor for git (Bug#12697).
3809 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3810 and it is configured in conf_post.h.
3811 (Fcall_process): Don't invoke both setsid and setpgid; the former
3812 is enough, if it exists.
3813 * callproc.c (Fcall_process, child_setup):
3814 * process.c (create_process): Use setpgid.
3815 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3817 * dispnew.c (init_display): Initialize the foreground group
3818 if we are running a tty display.
3819 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3820 * lisp.h (init_foreground_group): New decl.
3821 * sysdep.c (inherited_pgroup): New static var.
3822 (init_foreground_group, tcsetpgrp_without_stopping)
3823 (narrow_foreground_group, widen_foreground_group): New functions.
3824 (init_sys_modes): Narrow foreground group.
3825 (reset_sys_modes): Widen foreground group.
3827 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3829 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3831 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3833 * minibuf.c (read_minibuf): Restore current buffer since
3834 choose_minibuf_frame calling Fset_frame_selected_window may
3835 change it (Bug#12766).
3837 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3839 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3841 2012-10-30 Kenichi Handa <handa@gnu.org>
3843 * font.c (Ffont_at): If WINDOW is specified and it is not
3844 displaying the current buffer, signal an error.
3846 2012-10-29 Daniel Colascione <dancol@dancol.org>
3848 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3849 In preparation for fixing bug#12739, move these functions from
3852 * coding.h, coding.c: ... to here, and compile them only when
3853 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3854 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3856 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3858 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3859 (timer_loop, getitimer, setitimer): Use it instead of
3860 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3862 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3865 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3867 * nsterm.m (NO_APPDEFINED_DATA): New define.

3870 (ns_select): Initialize t from last_appdefined_event_data instead
3871 of [last_appdefined_event data1].
3872 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3873 remove last_appdefined_event (Bug#12698).
3875 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3877 * frame.c (x_set_font): Catch internal error.
3879 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3881 Avoid overflow in w32 implementation of interval timers.
3882 When possible, for ITIMER_PROF count only times the main thread
3884 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3885 'volatile ULONGLONG' types. All the other data which was
3886 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3887 (GetThreadTimes_Proc): New typedef.
3888 (w32_get_timer_time): New function, returns a suitable time value
3890 (timer_loop): Enter critical section when accessing ULONGLONG
3891 values of the itimer_data struct, as these accesses are no longer
3892 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3893 Remove unused variable.
3894 (init_timers): Initialize s_pfn_Get_Thread_Times.
3895 (start_timer_thread): Don't assign itimer->caller_thread here.
3896 (getitimer): Assign itimer->caller_thread here.

3902 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3903 mouse movement events if the menu bar is active. This avoids
3904 producing a busy "hour-glass" cursor by Windows if the mouse
3905 pointer is positioned over a tooltip shown for some menu item.
3907 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3909 Don't assume process IDs fit in int.
3910 * emacs.c (shut_down_emacs) [!DOS_NT]:
3911 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3912 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3913 Use pid_t, not int, to store process IDs, as 'int'
3914 is not wide enough on a few platforms (e.g., AIX and IRIX).
3916 2012-10-23 Kenichi Handa <handa@gnu.org>
3918 The following change is to make face-font-rescale-alist work
3919 correctly for non-ASCII fonts.

3937 2012-10-21 Glenn Morris <rgm@gnu.org>
3939 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3941 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3943 Port to OpenBSD 5.1.
3944 * frame.c (Fmouse_position, Fmouse_pixel_position):
3945 * xdisp.c (produce_stretch_glyph):
3946 Declare local vars only when they're needed.
3947 This is clearer and avoids a warning on OpenBSD about unused vars.
3948 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3949 This is safer, and avoids OpenBSD warnings about unused vars.
3950 * keyboard.c (record_menu_key): Remove unnecessary decl.
3951 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3952 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3953 as our definition clashes with OpenBSD's.
3954 * xfaces.c (load_face_colors, check_lface_attrs)
3955 (get_lface_attributes_no_remap, get_lface_attributes)
3956 (lface_fully_specified_p, x_supports_face_attributes_p)
3957 (tty_supports_face_attributes_p, face_fontset, realize_face)
3958 (realize_x_face, realize_tty_face):
3959 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3960 merely Lisp_Object *. This is more informative and avoids
3961 a warning on OpenBSD about accessing beyond an object's size.
3963 2012-10-20 Chong Yidong <cyd@gnu.org>
3965 * lread.c (Fload): Doc fix (Bug#12592).
3967 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
3969 * font.c (Ffont_at): Fix previous change.
3971 2012-10-19 Eli Zaretskii <eliz@gnu.org>
3973 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
3974 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

3991 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3992 (staticpro): If we run out of staticpro slots, die with an
3993 informative error instead of just calling emacs_abort.
3995 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3997 Fix two flaws reported by Dmitry Antipov.
3998 * window.c (Ftemp_output_buffer_show): Remove.

4119 removed or renamed by some other process immediately after Emacs
4120 writes it but before Emacs stats it. Do not assume that stat (or

4152 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
4153 instead of calling 'stat', when what's needed is to check whether
4154 a file exists. This avoids expensive system calls on MS-Windows.
4157 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.

4196 Use bool for booleans.
4197 * lread.c (safe_to_load_version): Rename from safe_to_load_p,

4251 Use unsigned for counter where wraparound-on-overflow is desired,
4252 since unsigned is guaranteed to have that behavior and signed is not.
4253 (read_char): Use ptrdiff_t for string length.
4254 (get_input_pending): Remove first argument, since it was always
4255 the same pointer-to-int (now pointer-to-boolean) &input_pending,
4256 and behave as if it had that value. Return new value of
4257 input_pending. All callers changed.
4258 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4259 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
4261 * keymap.c (push_key_description): Omit last arg, which was always 1.
4262 All callers changed.
4264 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.

4282 Don't include termopts.h.
4284 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
4286 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
4288 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4290 * commands.h (immediate_quit): Remove duplicate decl.
4292 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
4294 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

4297 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
4299 2012-10-09 Eli Zaretskii <eliz@gnu.org>
4301 * w32fns.c (w32_last_error): Change the return value to DWORD, to
4302 match what GetLastError returns. Explain why the function is
4305 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4306 'is_tooltip_frame', to avoid confusion with its global namesake.
4308 2012-10-08 Daniel Colascione <dancol@dancol.org>
4310 * xdisp.c (start_hourglass): Call w32_note_current_window when
4311 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4312 build that caused Emacs to display the hourglass cursor forever.
4314 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4315 which is broken under remote desktop, calculate the number of
4316 colors available for a display based on the display's number of
4317 planes and number of bits per pixel per plane. (bug#10397).
4319 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4321 * nsfont.m (Vfonts_in_cache): New variable.
4322 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4323 are used. Add cached fonts to Vfonts_in_cache.
4324 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4326 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4328 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4330 (FONT_H): Define after FRAME_H.
4331 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4332 Update dependencies.
4334 * w32term.c: Remove leftover declaration of keyboard_codepage.
4336 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4338 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4339 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4340 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4341 (GLOBAL_SOURCES): Add cygw32.c.

4345 ($(BLD)/w32fns.$(O)):
4346 ($(BLD)/w32heap.$(O)):
4347 ($(BLD)/w32menu.$(O)):
4348 ($(BLD)/w32proc.$(O)): Add w32common.h.
4350 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4352 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4354 2012-10-08 Daniel Colascione <dancol@dancol.org>
4356 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4357 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4358 accidental message numbering hole. Change other messages to
4361 * w32select.h (HAVE_W32SELECT): Remove.
4363 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4364 w32common.h instead of w32heap.h.
4366 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4367 (get_allocation_unit, get_processor_type, get_w32_major_version)
4368 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4369 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4370 (OS_NT, os_subtype, cache_system_info): Move declarations to
4373 * w32heap.c: Include w32common.h.
4374 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4375 (w32_minor_version, w32_build_number, w32_subtype):
4376 Remove duplicate definitions.
4378 * w32fns.c: Include w32common.h; include w32heap.h only in
4381 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4382 Use `report_file_error' instead of `error' in order to better
4383 inform users of what went wrong. Increase NTGUI_UNICODE file
4384 dialog box file name length to 32k, the maximum allowed by the NT
4387 * w32common.h: New file.
4388 (ROUND_UP, ROUND_DOWN, get_page_size)
4389 (get_allocation_unit, get_processor_type, get_w32_major_version)
4390 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4391 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4392 (OS_NT, os_subtype, cache_system_info): Move here.
4394 * unexw32.c, unexcw.c: Include w32common.h.
4396 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4397 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4398 to call syms_of_w32select.
4400 * cygw32.h: Remove obsolete EXFUN declarations.
4402 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4404 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4405 of w32inevt.o from SOME_MACHINE_OBJECTS.
4407 2012-10-08 Daniel Colascione <dancol@dancol.org>
4409 * image.c: Permanent fix for JPEG compilation issue --- limit
4410 jpeglib `boolean' redefinition to Cygwin builds.
4412 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4414 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4416 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4419 2012-10-08 Daniel Colascione <dancol@dancol.org>
4421 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4422 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4423 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4424 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4425 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4426 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4427 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4428 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4429 now a supported configuration.
4431 * Makefile.in: consolidate image variables into LIBIMAGE; add
4432 W32_OBJ and W32_LIBS. Compile new files.
4435 (_DebPrint) declare tracing facility for W32 debugging. We need
4436 to unify tracing later.
4438 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4439 unconditional use of W32 Unicode functions. Cygwin runs only on
4440 100% Unicode operating systems.
4442 * cygw32.c: New file. Define Cygwin-specific facilities.
4443 (Fcygwin_convert_path_to_windows)
4444 (Fcygwin_convert_path_from_windows): New user functions for
4445 accessing Cygwin path-munging routines.
4447 * cygw32.h: New file.
4448 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4449 UTF-16LE strings temporarily inside non-Lisp-visible string
4452 (w32_strerror): Just what it says on the tin.
4454 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4455 also run for Cygwin; both systems have the same problem with using
4456 GUI facilities in a forked child. Also call syms_of_cygw32,
4457 syms_of_w32select in correct places.
4459 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4460 needs fork-then-exec for daemon launching.
4462 * font.h: Include frame.h.
4464 * image.c: Use the image library cache machinery only when we're
4465 compiling for native WINDOWSNT; Cygwin can use shared libraries
4466 like any other Unixlike system.
4468 * keyboard.c: Clarify a comment regarding the input loop.
4470 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4471 functions directly instead of trying to detect at runtime that our
4472 host operating system supports them. We make this change for two
4473 reasons: Cygwin lacks support for the multibyte character
4474 conversion functions used by the legacy menu code, and Cygwin
4475 never needs to rely on non-Unicode APIs.
4477 * unexw32.c (hinst): Declare extern.
4479 * w32.c: Change header order;
4480 (w32_strerror): Move to w32fns.c because we need it for
4481 non-WINDOWSNT builds.
4483 * w32.h: Add #error macro to make sure we don't include w32.h for
4484 Cygwin builds. Remove w32select declarations.
4486 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4487 w32fns.c. w32console.c is WINDOWSNT-only.
4489 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4490 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4492 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4493 (w32_major_version, w32_minor_version, w32_build_number)
4494 (os_subtype, sound_type): Define here
4495 (w32_defined_color): Make color parameter const for consistency
4496 with other _defined_color functions.
4497 (w32_createwindow): Unconditionally call w32_init_class instead of
4498 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4499 through the code is complex and unnecessary because class
4500 registration is practically free.
4501 (w32_name_of_message): New EMACSDEBUG-only function.
4502 (Fset_message_beep): Move here
4503 (Fx_open_connection): Require that the display name for Windows be
4504 "w32" for consistency, emacsclient disambiguation, and maybe, one
4505 day, multi-window-system support.
4506 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4507 Cygwin files for W32 GUI facilities, since these clearly don't
4508 expect Cygwin names.
4509 (_DebPrint): Define.
4510 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4511 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4512 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4513 (w32_last_error): Remove.
4515 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4517 * w32heap.c (syspage_mask): Declare here.
4518 (cache_system_info): Remove.
4520 * w32inevt.c (faked_key): Define globally, not statically.
4521 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4522 (w32_console_toggle_lock_key): Move to w32fns.c.
4524 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4526 * w32proc.c (_DebPrint): Move to w32fns.c.
4527 * w32select.c: Include string.h, stdio.h for Cygwin.
4528 * w32select.h: New File.
4530 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4532 (w32_message_fd): New variable. Under Cygwin, holds the file
4533 descriptor the system used to tell us about pending thread
4536 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4537 that prevented compilation under non-WINDOWSNT systems.
4539 (w32_initialize): Open /dev/windows and assign it to
4540 w32_message_fd. Provide w32 feature.
4542 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4543 (WM_EMACS_INPUT_READY): add.
4544 (prepend_msg, w32_message_fd): Declare globally.
4547 (keyboard_handle): Use only when WINDOWSNT.
4548 (notify_msg_ready): New function. Posts a message to the main
4549 thread's message queue under CYGWIN, which wakes up the main
4550 thread from select(2) by making the /dev/windows file descriptor
4551 ready. Under WINDOWSNT, it sets an event the same way the old
4554 (post, prepend_msg): Actually call notify_msg_ready instead of
4555 setting the input event directly.
4557 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4559 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4560 but it still has blocs in it, don't return it to the system,
4561 instead of aborting. (Bug#12402)
4563 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4565 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4567 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4568 MAC_OS_X_VERSION_10_6.

4573 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4575 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4576 MAC_OS_X_VERSION_10_4.
4578 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4579 MAC_OS_X_VERSION_10_2.
4581 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4583 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4584 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4586 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4587 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4588 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4589 Remove ns_in_resize check.
4590 (ns_clear_frame_area): Remove resize handle code.
4592 * nsfns.m (ns_in_resize): Remove.
4593 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4594 Remove ns_in_resize check.
4596 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4598 Improve sys_siglist detection.
4599 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4600 defined as a macro, as is done in Solaris.
4601 (sys_siglist_entries): New macro.
4602 (save_strsignal): Use it.
4603 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4604 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4606 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4608 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4609 fullscreen/Fullscreen.
4611 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4612 tobar_height is new.
4614 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4615 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4616 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4617 (windowDidResize:): Check for correct window if old style fullscreen.
4618 Capitalize word in comment. Remove incorrect comment.
4619 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4620 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4621 error in drawing background.
4622 (toggleFullScreen:): Remove comment. Rearrange calls.
4623 Set toolbar values to zero, save old height in tobar_height.
4624 Restore tool bar height when leaving fullscreen.
4625 (canBecomeMainWindow): New function.
4627 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>

4631 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4633 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4635 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4636 that time stamps of directories could also be changed.
4637 Don't request the too broad GENERIC_WRITE, only the more restrictive
4638 FILE_WRITE_ATTRIBUTES access rights.
4640 * fileio.c (Fset_file_times): Special-case ignoring errors for
4641 directories only on MSDOS, not on MS-Windows.
4643 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4645 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4647 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4649 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4650 see whether CreateFile failed.
4652 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4654 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4655 to avoid similar races.
4656 * keyboard.c (pending_signals): Now bool, not int.
4658 Port timers to OpenBSD, plus check for timer failures.
4659 OpenBSD problem reported by Han Boetes.
4660 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4662 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4663 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4664 like OpenBSD, which has timer_settime but does not declare it.
4665 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4666 whether to use itimerspec-related primitives. All uses of
4667 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4669 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4671 * profiler.c (handle_profiler_signal): Fix a malloc race
4672 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4674 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4676 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4678 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4680 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4681 consistent with the change in return value of 'safe_strsignal'.
4683 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4685 Prefer plain 'static' to 'static inline' (Bug#12541).

4687 (bidi_set_sor_type, bidi_push_embedding_level)
4688 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

4693 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4694 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4695 Now 'static', not 'static inline'.
4697 Count overruns when profiling; change units to ns.
4698 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4699 Give extra weight to samples after overruns, to attempt to count
4700 the time more accurately.
4701 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4702 the underlying primitives nominally do ns.
4703 (Fprofiler_cpu_start): Document the change. Mention that
4704 the sampling intervals are only approximate.
4706 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4708 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4710 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4711 case for the special 0 coding-system.
4713 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4714 (Fmake_overlay): Remove redundant tests.
4715 (fix_start_end_in_overlays): Remove redundant recentering.
4717 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4719 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4720 Update dependencies.
4722 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4724 Fix a malloc race condition involving strsignal.
4725 A signal can arrive in the middle of a malloc, and Emacs's signal
4726 handler can invoke strsignal, which can invoke malloc, which is
4727 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4728 Fix it by altering the signal handler so that it does not invoke
4730 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4731 * process.c (status_message): Use const pointer, in case strsignal
4732 is #defined to safe_strsignal.
4733 * sysdep.c (sys_siglist, init_signals): Always define and
4734 initialize a substitute sys_siglist if the system does not define
4735 one, even if HAVE_STRSIGNAL.
4736 (safe_strsignal): Rename from strsignal. Always define,
4737 using sys_siglist. Return a const pointer.
4738 * syssignal.h (safe_strsignal): New decl.
4739 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4741 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4743 * w32proc.c (timer_loop): Fix code that waits for timer
4744 expiration, to avoid high CPU usage.
4746 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4748 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4749 (sweep_weak_table): Remove redundant prototypes.
4751 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4753 * emacs.c: Move the inclusion of TERM_HEADER after including
4754 windows.h on WINDOWSNT. This avoids compilation problems with
4757 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4759 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4760 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4761 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4762 as the previous version used 'void *'.
4764 * ralloc.c (ROUNDUP): Fix last change.
4765 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4768 * w32proc.c <disable_itimers>: New static flag.
4769 (init_timers): Initialize it to zero, after creating the critical
4770 sections used by the timer threads.
4771 (term_timers): Set to 1 before deleting the critical sections.
4772 (getitimer, setitimer): If disable_itimers is non-zero, return an
4773 error indication without doing anything. Reported by Fabrice
4774 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4775 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4777 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4780 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4781 term_ntproc after all the other bookkeeping, to get timers working
4782 as long as possible.
4784 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4786 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4787 Suggested by Juri Linkov in
4788 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4790 Prefer plain 'static' to 'static inline' (Bug#12541).
4791 With static functions, modern compilers inline pretty well by
4792 themselves; advice from programmers often hurts as much as it helps.
4793 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4794 this change shrinks the text size of the Emacs executable by 1.1%
4795 without affecting CPU significantly in my benchmark.
4796 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

4876 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4878 Revert the FOLLOW-SYMLINKS change for file-attributes.
4879 Doing it right would require several changes to Tramp, and there's
4880 not enough time to get that tested before the freeze today.
4881 * dired.c (directory_files_internal, Ffile_attributes):
4884 * frame.c (x_report_frame_params): Port better to wider ints.
4885 Do not assume that EMACS_UINT is the same width as uprintmax_t,

5084 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
5086 (enum profiler_cpu_running): New enum.
5087 (profiler_cpu_running): Now of that enum type, not bool.
5088 All uses changed to store the new value.
5089 (handle_profiler_signal): Rename from sigprof_handler_1,
5090 for consistency with other handlers. Do not check whether
5091 cpu_log is a hash-table if garbage collecting, since it
5092 doesn't matter in that case.
5093 (deliver_profiler_signal): Rename from sigprof_handler,
5094 for consistency with other handlers.
5095 (setup_cpu_timer): New function, with much of what used to be in
5096 Fprofiler_cpu_start. Check for out-of-range argument.
5097 Prefer timer_settime if available, and prefer
5098 thread cputime clocks, then process cputime clocks, then
5099 monotonic clocks, to the old realtime clock. Use make_timeval
5100 to round more-correctly when falling back to setitimer.
5101 (Fprofiler_cpu_start): Use it.
5102 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5103 Don't assume that passing NULL as the 2nd argument of setitimer
5104 is the same as passing a pointer to all-zero storage.
5105 Ignore SIGPROF afterwards.
5106 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5107 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5108 non-fatal signal handlers. Ignore SIGPROF on startup.
5109 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5110 in profiler.c, since sysdep.c now uses it.
5112 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
5113 Suggested by Eli Zaretskii in
5114 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

5127 (Fbacktrace_frame): Adjust accordingly.
5129 2012-09-28 Glenn Morris <rgm@gnu.org>
5131 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
5132 (Frun_hook_with_args_until_failure): Doc fixes.
5134 2012-09-28 Eli Zaretskii <eliz@gnu.org>
5136 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from

5164 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
5166 * character.h (MAYBE_UNIFY_CHAR): Remove.
5167 * charset.c, charset.h (maybe_unify_char): Now static.
5168 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5169 Since this stuff is now private to charset.c, there's no need for
5170 a public macro and no need to inline by hand.

5201 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
5203 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
5205 Prefer POSIX timers if available.
5206 They avoid a race if the timer is too close to the current time.
5207 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
5208 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
5209 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
5211 2012-09-25 Eli Zaretskii <eliz@gnu.org>

5214 CHAR_STRING_ADVANCE.
5215 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
5216 STRING_CHAR_ADVANCE.

5225 * image.c (reset_image_types): New function.
5227 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

5234 * w32.h (Vlibrary_cache): Do not declare.
5236 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5238 * w32proc.c (sys_signal): Handle all signals defined by the
5239 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5240 handlers for signals supported by Windows. Don't override
5241 term_ntproc as the handler for SIGABRT.
5242 (sigaction): Rewrite to call sys_signal instead of duplicating its
5244 (sys_kill): Improve commentary.
5246 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5247 consistency with a signature of a signal handler. All callers
5249 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5250 install term_ntproc as a signal handler for SIGABRT, as that
5251 should be done by the dumped Emacs.
5253 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5255 * w32select.c (term_w32select): Protect against repeated
5256 invocation by setting clipboard_owner to NULL after calling
5259 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5260 and term_ntproc to their modified signatures.
5262 * character.c (char_string, string_char): Remove calls to
5263 MAYBE_UNIFY_CHAR. See the discussion starting at
5264 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
5267 2012-09-25 Chong Yidong <cyd@gnu.org>
5269 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
5271 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5273 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5274 when encountering an unknown bytecode.
5276 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5278 image.c, indent.c: Use bool for booleans.
5279 * dispextern.h (struct image_type): Members valid_p, load, init
5280 now return bool, not int. All uses changed.
5281 * image.c: Omit unnecessary static decls.
5282 (x_create_bitmap_mask, x_build_heuristic_mask):
5283 Return void, not int, since callers don't care about the return value.

5314 2012-09-24 Chong Yidong <cyd@gnu.org>
5316 * chartab.c (Fset_char_table_default): Obsolete function removed.
5318 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5320 Move pid_t related decls out of lisp.h.
5321 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5322 (interruptible_wait_for_termination):
5323 Move these decls from lisp.h to syswait.h, since they use pid_t.
5324 Needed on FreeBSD; see Herbert J. Skuhra in
5325 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5326 * callproc.c: Include syswait.h.

5346 Use bool for boolean.
5347 * gtkutil.c (xg_update_frame_menubar):

5372 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5374 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5375 fatal_error_backtrace.
5377 * w32proc.c (sys_kill): Undo last change: don't do anything when
5378 invoked to deliver SIGABRT to our own process. This is now
5379 handled by emacs_raise.
5381 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5383 * w32term.c (w32_read_socket): Remove leftover reference to
5384 interrupt_input_pending.
5386 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5388 Do not use SA_NODEFER.
5389 Problem reported by Dani Moncayo in
5390 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5392 * sysdep.c (emacs_abort): Do not reset signal handler.
5393 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5394 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5395 wanted even on POSIXish hosts, and it doesn't work on Windows.
5397 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5399 * xterm.c (x_term_init): Call fixup_locale before and after calling
5400 gtk_init (Bug#12392).
5402 2012-09-23 Chong Yidong <cyd@gnu.org>
5404 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5405 Vdynamic_library_alist.
5407 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5408 (Fgnutls_available_p): Caller changed.
5410 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5411 (Flibxml_parse_xml_region): Likewise.
5413 * dispextern.h (struct image_type): Remove arg from init function.
5415 * image.c (Finit_image_library, lookup_image_type)
5416 (define_image_type): Remove now-unneeded second arg.
5417 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5418 (init_tiff_functions, init_gif_functions, init_svg_functions):
5419 Arglist and w32_delayed_load calling convention changed.
5420 (gs_type): Remove init_gs_functions; there is no such function.
5421 (valid_image_p, make_image): Fix caller to lookup_image_type.
5423 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5425 Simplify and avoid signal-handling races (Bug#12471).
5427 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5428 Avoid recursive loop if there's a fatal error in the function itself.
5429 * atimer.c (pending_atimers):
5430 * blockinput.h: Don't include "atimer.h"; no longer needed.
5431 (interrupt_input_pending): Remove. All uses removed.
5432 pending_signals now counts both atimers and ordinary interrupts.
5433 This is less racy than having three separate pending-signal flags.
5434 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5436 Rename from their upper-case counterparts BLOCK_INPUT,
5437 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5438 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5439 This makes it easier to access volatile variables more accurately.
5440 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5441 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5442 that's more reliable if the code is buggy and sets
5443 interrupt_input_blocked to a negative value. All uses changed.
5444 * atimer.c (deliver_alarm_signal):
5445 Remove. No need to deliver this to the parent; any thread can
5446 handle this signal now. All uses replaced by underlying handler.
5447 * atimer.c (turn_on_atimers):
5448 * dispnew.c (handle_window_change_signal):
5449 * emacs.c (handle_danger_signal):
5450 * keyboard.c (kbd_buffer_get_event):
5451 Don't reestablish signal handler; not needed with sigaction.
5452 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5454 Rework to avoid unnecessary accesses to volatile variables.
5455 (UNBLOCK_INPUT_TO): Now a function.
5456 (totally_unblock_input, unblock_input): New decls.
5457 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5458 (init_data): Remove. Necessary stuff now done in init_signal.
5459 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5460 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5461 (fatal_error_code): Remove; no longer needed.
5462 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5463 it doesn't always backtrace. All uses changed. No need to reset
5464 signal to default, since sigaction and/or die does that for us now.
5465 Use emacs_raise (FOO), not kill (getpid (), FOO).
5466 (main): Check more-accurately whether we're dumping.
5467 Move fatal-error setup to sysdep.c
5468 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5469 * gtkutil.c (xg_get_file_name, xg_get_font):
5470 Remove no-longer-needed signal-mask manipulation.
5471 * keyboard.c, process.c (POLL_FOR_INPUT):
5472 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5473 * keyboard.c (read_avail_input): Remove.
5474 All uses replaced by gobble_input.
5475 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5476 (kbd_buffer_store_event_hold, gobble_input):
5477 (record_asynch_buffer_change) [USABLE_SIGIO]:
5478 (store_user_signal_events):
5479 No need to mess with signal mask.
5480 (gobble_input): If blocking input and there are terminals, simply
5481 set pending_signals to 1 and return. All hooks changed to not
5482 worry about whether input is blocked.
5483 (process_pending_signals): Clear pending_signals before processing
5484 them, in case a signal comes in while we're processing.
5485 By convention callers now test pending_signals before calling us.
5486 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5487 New functions, to support changes to blockinput.h.
5488 (handle_input_available_signal): Now extern.
5489 (reinvoke_input_signal): Remove. All uses replaced by
5491 (quit_count): Now volatile, since a signal handler uses it.
5492 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5493 All callers changed. Block SIGINT only if not already blocked.
5494 Clear sigmask reliably, even if Fsignal returns, which it can.
5495 Omit unnecessary accesses to volatile var.
5496 (quit_throw_to_read_char): No need to restore sigmask.
5497 * keyboard.c (gobble_input, handle_user_signal):
5498 * process.c (wait_reading_process_output):
5499 Call signal-handling code rather than killing ourselves.
5500 * lisp.h: Include <float.h>, for...
5501 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5502 (pending_signals): Now volatile.
5503 (syms_of_data): Now const if IEEE floating point.
5504 (handle_input_available_signal) [USABLE_SIGIO]:
5505 (terminate_due_to_signal, record_child_status_change): New decls.
5506 * process.c (create_process): Avoid disaster if memory is exhausted
5507 while we're processing a vfork, by tightening the critical section
5509 (send_process_frame, process_sent_to, handle_pipe_signal)
5510 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5512 (send_process): No need for setjmp/longjmp any more, since the
5513 SIGPIPE stuff is now gone. Instead, report an error if errno
5515 (record_child_status_change): Now extern. PID and W are now args.
5516 Return void, not bool. All callers changed.
5517 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5518 Remove. All uses removed. This bug should be fixed now in a
5520 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5521 and record the child status change directly. This avoids the
5522 need to futz with the signal mask.
5523 (process_fatal_action): Move here from emacs.c.
5524 (emacs_sigaction_flags): New function, containing
5525 much of what used to be in emacs_sigaction_init.
5526 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5527 caught by emacs, to make races less likely.
5528 (deliver_process_signal): Rename from handle_on_main_thread.
5530 (BACKTRACE_LIMIT_MAX): Now at top level.
5531 (thread_backtrace_buffer, threadback_backtrace_pointers):
5533 (deliver_thread_signal, deliver_fatal_thread_signal):
5534 New functions, for more-accurate delivery of thread-specific signals.
5535 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5536 (deliver_arith_signal): Handle in this thread, not
5537 in the main thread, since it's triggered by this thread.
5538 (maybe_fatal_sig): New function.
5539 (init_signals): New arg DUMPING so that we can be more accurate
5540 about whether we're dumping. Caller changed.
5541 Treat thread-specific signals differently from process-general signals.
5542 Block all signals while handling fatal error; that's safer.
5543 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5545 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5546 Ignore SIGPIPE unless batch.
5547 (emacs_backtrace): Output backtrace for the appropriate thread,
5548 which is not necessarily the main thread.
5549 * syssignal.h: Include <stdbool.h>.
5550 (emacs_raise): New macro.
5551 * xterm.c (x_connection_signal): Remove; no longer needed
5552 now that we use sigaction.
5553 (x_connection_closed): No need to mess with sigmask now.
5554 (x_initialize): No need to reset SIGPIPE handler here, since
5555 init_signals does this for us now.
5557 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5559 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5560 background rect may be larger (Bug#12245).
5562 2012-09-23 Chong Yidong <cyd@gnu.org>
5564 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5566 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5568 * .gdbinit: Just stop at fatal_error_backtrace.
5569 See Stefan Monnier's request in
5570 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5571 Remove no-longer-used query of system type.
5573 2012-09-22 Chong Yidong <cyd@gnu.org>
5575 * search.c (Freplace_match): Doc fix (Bug#12325).
5577 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5579 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5580 (Fline_end_position): Doc fix.
5582 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5584 2012-09-22 Chong Yidong <cyd@gnu.org>
5586 * dispextern.h (struct image_type): Add new slot, storing a type
5587 initialization function.
5589 * image.c (define_image_type): Call the image initializer function
5590 if it is defined. Arguments and return value changed.
5591 (valid_image_p, make_image): Callers changed.
5592 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5593 (gif_type, imagemagick_type, svg_type, gs_type):
5594 Add initialization functions.
5595 (Finit_image_library): Call lookup_image_type.
5596 (CHECK_LIB_AVAILABLE): Macro deleted.
5597 (lookup_image_type): Call define_image_type here, rather than via
5598 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5599 (syms_of_image): Move define_image_type calls for xbm_type and
5600 pbm_type to lookup_image_type.
5602 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5604 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5605 'idle_timers' from here ...
5606 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5607 lists, to avoid infloops when the timer does something stupid,
5608 like reinvoke itself with the same or smaller time-out.
5611 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5613 * window.c (Fsplit_window_internal): Handle only Qt value of
5614 Vwindow_combination_limit separately.
5615 (Qtemp_buffer_resize): New symbol.
5616 (Vwindow_combination_limit): New default value.
5619 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5621 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5622 the new overlay string. (Bug#10159)
5624 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5626 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5627 or that fprintf is async-signal-safe. POSIX doesn't require
5630 2012-09-22 Chong Yidong <cyd@gnu.org>
5632 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5635 2012-09-22 Kenichi Handa <handa@gnu.org>
5637 * composite.c (composition_reseat_it): Handle the case that a
5638 grapheme cluster is not covered by a single font (Bug#12352).
5640 2012-09-21 Chong Yidong <cyd@gnu.org>
5642 * image.c (define_image_type): Avoid adding duplicate types to
5643 image_types (Bug#12463). Suggested by Jörg Walter.
5645 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5647 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5648 (print_load_command_name): Add case LC_DATA_IN_CODE.
5649 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5651 2012-09-21 Glenn Morris <rgm@gnu.org>
5653 * eval.c (Frun_hook_with_args_until_success)
5654 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5656 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5658 * fileio.c (Ffile_selinux_context): Only call freecon when
5659 lgetfilecon succeeded.
5660 (Fset_file_selinux_context): Likewise. (Bug#12444)
5662 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5664 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5665 reordering, locate the cursor by calling set_cursor_from_row; if
5666 that fails, clear the desired glyph matrix before returning a
5667 failure indication to the caller. Fixes leaving garbled display
5668 when fast scrolling with a down-key. (Bug#12403)
5669 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5670 scrolling through multibyte text.
5672 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5674 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5675 calling mark_vectorlike since that's the one that marks the window.
5676 (mark_discard_killed_buffers): Mark the final cdr.
5677 * window.h (struct window): Move prev/next_buffers to the
5678 non-standard fields.
5679 * window.c (make_window): Initialize prev/next_buffers manually.
5681 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5683 Omit unused arg EXPECTED from socket hooks.
5684 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5685 * nsterm.m (ns_term_init):
5686 * termhooks.h (struct terminal.read_socket_hook):
5687 * w32inevt.c (w32_console_read_socket):
5688 * w32term.c (w32_read_socket):
5689 * xterm.c (XTread_socket):
5690 Omit unused arg EXPECTED. All callers changed.
5691 (store_user_signal_events): Return void, not int, since callers no
5692 longer care about the return value. All uses changed.
5694 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5696 * w32gui.h (XParseGeometry): Do not declare.
5698 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5700 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5701 Ignore 'expected'. See Eli Zaretskii in
5702 <http://bugs.gnu.org/12471#8> (last line).
5704 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5705 (XParseGeometry): Now static. Substitute extremal values for
5706 values that are out of range.
5708 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5710 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5712 * nsfns.m (XParseGeometry): Remove.
5713 (Fx_create_frame): Call x_set_offset to correctly interpret
5714 top_pos in geometry.
5716 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5717 (Fx_parse_geometry): If there is a space in string, call
5718 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5720 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5722 * search.c (scan_buffer): Use character positions in calls to
5723 region_cache_forward and region_cache_backward, not byte
5724 positions. (Bug#12196)
5726 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5727 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5729 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5730 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5731 emacs_blocked_malloc, now deleted.
5733 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5735 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5736 The workaround was for improving performance on Solaris 2.4, but
5737 is getting in the way now. Emacs will still work if someone is
5738 still running Solaris 2.4 in a museum somewhere; Sun dropped
5739 support for Solaris 2.4 in 2003.
5740 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5741 * process.c (create_process) [HAVE_WORKING_VFORK]:
5742 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5743 since Emacs no longer uses vfork on that platform.
5745 2012-09-17 Glenn Morris <rgm@gnu.org>
5747 * emacs.c: Use COPYRIGHT.
5749 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5751 Remove configure's --without-sync-input option (Bug#12450).
5752 When auditing signal-handling in preparation for cleaning it up,
5753 I found that SYNC_INPUT has race conditions and would be a real
5754 pain to fix. Since it's an undocumented and deprecated
5755 configure-time option, now seems like a good time to remove it.
5756 Also see <http://bugs.gnu.org/11080#16>.
5757 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5758 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5759 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5760 (malloc_hysteresis):
5761 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5762 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5763 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5764 (dont_register_blocks, bytes_used_when_reconsidered)
5765 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5766 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5767 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5768 Remove. All uses removed.
5769 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5770 implementation, one that depends on whether the new macro
5771 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5773 * atimer.c (run_timers, handle_alarm_signal):
5774 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5775 (handle_async_input, process_pending_signals)
5776 (handle_input_available_signal, init_keyboard):
5777 * nsterm.m (ns_read_socket):
5778 * process.c (wait_reading_process_output):
5779 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5780 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5782 * xterm.c (XTread_socket):
5784 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5785 * eval.c (handling_signal): Remove. All uses removed.
5786 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5787 All uses replaced with the SYNC_INPUT version.
5788 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5790 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5793 * font.c (Ffont_shape_gstring): Remove unused local.
5795 2012-09-16 Glenn Morris <rgm@gnu.org>
5797 * Makefile.in (clean): No longer run nextstep's clean.
5799 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5801 (ns-app): Move here from ns.mk, and simplify.
5802 (clean): Simplify nextstep entry.
5803 * ns.mk: Remove file.
5805 2012-09-17 Kenichi Handa <handa@gnu.org>
5807 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5808 not covert the last few charactes.
5810 2012-09-16 Kenichi Handa <handa@gnu.org>
5812 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5813 here, but just check the validity of glyphs in the glyph-string.
5815 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5817 * window.c (Fwindow_parameter, Fset_window_parameter):
5818 Accept any window as argument (Bug#12452).
5820 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5822 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5823 to ns_term_init to avoid memory leak.
5825 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5826 explicit retain/release.
5827 (ns_term_init): Only allow one display. Initialize outerpool and
5830 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5832 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5833 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5834 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5835 the Microsoft problem in a different way, by altering ../nt/config.nt.
5837 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5852 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5853 by lisp.h. This completes removal of setjmp.h inclusion
5854 erroneously announced in the previous commit. (Bug#12446)
5856 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5859 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5860 not defined as a macro. The latter happens on MS-Windows.
5863 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5865 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5866 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5867 Some instances of '#include <setjmp.h>' removed, if the
5868 only reason for the instance was because "lisp.h" was included.
5869 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5870 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5871 and _longjmp with the new symbols. Emacs already uses _setjmp if
5872 available, so this change affects only POSIXish hosts that have
5873 sigsetjmp but not _setjmp, such as some versions of Solaris and
5874 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5875 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5876 (png_load_body) [HAVE_PNG]:
5877 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5878 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5879 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5880 since PNG requires jmp_buf. This is the only exception to the
5881 general rule that we now use sys_setjmp and sys_longjmp.
5882 This exception is OK since this code does not change the signal
5883 mask or longjmp out of a signal handler.
5885 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5887 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5888 Include "syssignal.h", for 'main_thread'.
5890 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5892 Avoid out-of-range marker position (Bug#12426).
5893 * insdel.c (replace_range, replace_range_2):
5894 Adjust markers before overlays, as suggested by comments.
5895 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5896 Remove redundant check before calling offset_intervals.
5898 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5900 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5901 current buffer (Bug#12387).
5903 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5905 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5907 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5909 Use a more backwards-compatible timer format (Bug#12430).
5910 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5911 vector element, not from the 4th, since PSECS is now at the end.
5912 (Fcurrent_idle_time): Doc fix.
5914 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5916 Function to mark objects and remove killed buffers at once.
5917 * alloc.c (discard_killed_buffers): Rename to ...
5918 (mark_discard_killed buffers) ... new name. Add marking
5919 of remaining objects. Fix comment. Adjust users.
5920 (mark_object): Do not touch frame buffer lists here.
5921 * frame.c (delete_frame): Reset frame buffer lists here.
5923 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5925 Better workaround for GNOME bug when --enable-gcc-warnings.
5926 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5927 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5928 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5930 Simplify SIGIO usage (Bug#12408).
5931 The code that dealt with SIGIO was crufty and confusing, e.g., it
5932 played tricks like "#undef SIGIO" but these tricks were not used
5933 consistently. Simplify mostly by not #undeffing standard symbols,
5934 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5935 or not as we please) rather than "defined SIGIO" (standard symbol
5936 that we probably shouldn't #undef).
5937 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5938 Modules that need it can include it.
5939 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5940 * dispextern.h (ignore_sigio): New decl.
5941 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5942 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5943 * emacs.c (shut_down_emacs):
5944 * keyboard.c (kbd_buffer_store_event_hold):
5945 Use ignore_sigio rather than invoking 'signal' directly.
5946 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5948 (FIONREAD, SIGIO): Do not #undef.
5949 (tty_read_avail_input): Use #error rather than a syntax error.
5950 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5951 for I_PIPE, used by SETUP_SLAVE_PTY.
5952 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5953 * sysdep.c (croak): Remove; no longer needed. This bit of
5954 temporary code, with Fred N. Fish's comment that it's temporary,
5955 has been in Emacs since at least 1992!
5956 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5957 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5958 * syssignal.h (croak): Remove decl.
5959 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5960 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5961 now that we're termios-only.
5962 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5963 * term.c (dissociate_if_controlling_tty): Use #error rather than
5966 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5967 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5968 to work around GNOME bug 683906.
5969 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5970 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5971 This works around GCC bug 54561.
5973 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5975 More fixes for 'volatile' and setjmp/longjmp.
5976 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5977 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5978 (png_load_body) [HAVE_PNG]:
5979 (jpeg_load_body) [HAVE_JPEG]:
5980 New function, with most of the old parent function's body.
5981 (png_load) [HAVE_PNG]:
5982 (jpeg_load) [HAVE_JPEG]:
5983 Invoke the new function, to avoid longjmp munging our locals.
5984 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5985 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5986 longjmp is passed 2, as the C standard doesn't guarantee this.
5987 Instead, store the failure code into mgr->failure_code.
5989 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5991 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5992 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5993 (syms_of_keyboard): Remove support for unread-command-char.
5995 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5997 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5998 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5999 violation. (Bug#12426)
6001 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6003 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6005 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6007 * eval.c: Add `inhibit-debugger'.
6008 (Qinhibit_debugger): New symbol.
6009 (call_debugger): Bind it instead of Qdebug_on_error.
6010 (maybe_call_debugger): Test Vinhibit_debugger.
6011 (syms_of_eval): Define inhibit-debugger.
6012 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6013 (syms_of_xdisp): Remove inhibit-debug-on-message.
6015 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6017 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6018 If a nonvolatile local variable is written before a _longjmp to
6019 the frame containing the variable, and is read after the _longjmp,
6020 the value read is indeterminate. Some local variables of type
6021 'struct handler' and 'struct catchtag' are used in this way, so
6022 mark each of their slots as volatile if the slot can be set before
6023 _longjmp and read afterwards.
6024 * lisp.h (struct handler): var and chosen_clause are now volatile.
6025 (struct catchtag): val, next, and pdlcount are now volatile.
6027 * bidi.c (bidi_push_it, bidi_pop_it):
6028 * fns.c (copy_hash_table):
6029 * image.c (define_image_type):
6030 * keyboard.c (kbd_buffer_store_event_hold):
6031 * process.c (Fprocess_send_eof):
6032 * xfaces.c (x_create_gc) [HAVE_NS]:
6033 * xgselect.c (xg_select):
6034 Prefer assignment to memcpy when either will do.
6036 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6037 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6038 time an item is removed. No need to mark this function 'inline';
6039 the compiler knows better than we do.
6041 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6043 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6044 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6045 to change_frame_size (Bug#12388).
6046 (windowDidResize:): Pass YES to updateFrameSize.
6048 * nsterm.h: Add delay parameter to updateFrameSize.
6050 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6052 Discard killed buffers from deleted window and frame objects.
6053 This reduces an amount of references to killed buffers and
6054 helps GC to reclaim them faster.
6055 * alloc.c (discard_killed_buffers): New function.
6056 (mark_object): Use it for deleted windows and frames.
6057 (mark_object): If symbol's value is set up for a killed buffer
6058 or deleted frame, restore its global binding.
6059 * data.c (swap_in_global_binding): Add GC notice.
6060 (swap_in_symval_forwarding): Use convenient set_blv_where.
6061 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6062 * window.h: ... to here.
6064 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6066 Convenient macro to check whether the buffer is live.
6067 * buffer.h (BUFFER_LIVE_P): New macro.
6068 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6069 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6071 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6073 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6074 composition cases (Bug#12364).
6076 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6077 overhang of succeeding glyphs overlapping box cursor.
6079 * w32term.c (x_draw_glyph_string): Likewise.
6081 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6083 Simplify, document, and port floating-point (Bug#12381).
6084 The porting part of this patch fixes bugs on non-IEEE platforms
6085 with frexp, ldexp, logb.
6086 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6088 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6089 support, by removing commented-out code and briefly listing the
6090 C89 functions excluded. The commented-out stuff was confusing
6091 maintenance, e.g., we thought we needed cbrt but it was commented out.
6092 (logb): Remove decl; no longer needed.
6093 (isfinite): New macro, if not already supplied.
6094 (isnan): Don't replace any existing macro.
6095 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6096 are present on all C89 platforms.
6097 (Ffrexp): Do not special-case zero, as frexp does the right thing
6099 (Flogb): Do not use logb, as it doesn't have the desired meaning
6100 on hosts that use non-base-2 floating point. Instead, stick with
6101 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6102 frexp, to avoid getting an unspecified result.
6104 * xdisp.c (Qinhibit_debug_on_message): Now static.
6106 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6108 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6109 NSBezierPath (Bug#12131).
6111 2012-09-10 Chong Yidong <cyd@gnu.org>
6113 * fns.c (Fdelq, Fdelete): Doc fix.
6115 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6117 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6118 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6120 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6122 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6123 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6126 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6128 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6129 left fringe if the window has a left margin. This avoids leaving
6130 traces of the cursor because its leftmost pixel is not drawn over.
6132 * dispnew.c (update_window_line): When the left margin area of a
6133 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6134 that screen line. (Bug#12277)
6136 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6138 Assume C89 or later for math functions (Bug#12381).
6139 This simplifies the code, and makes it a bit smaller and faster,
6140 and (most important) makes it easier to clean up signal handling
6141 since we can stop worring about floating-point exceptions in
6142 library code. That was a problem before C89, but the problem
6143 went away many years ago on all practical Emacs targets.
6144 * data.c, image.c, lread.c, print.c:
6145 Don't include <math.h>; no longer needed.
6146 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6147 might be autoconfigured, as that never happens.
6149 * doprnt.c (DBL_MAX_10_EXP):
6150 * print.c (DBL_DIG):
6151 Remove. C89 or later always defines these.
6152 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6153 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6154 (arith_error, domain_error, domain_error2):
6155 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6156 no longer needed -- we simply return what C returns. All uses removed.
6157 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6159 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6160 Remove. All uses expanded, as these macros are no longer used
6161 more than once and are now more trouble than they're worth.
6162 (Ftan): Use tan, not sin / cos.
6163 (Flogb): Assume C89 frexp.
6164 (fmod_float): Assume C89 fmod.
6165 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6166 (init_floatfns): Remove. All uses removed.
6168 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6170 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6171 compositeToPoint for OSX < 10.6 (Bug#12390).
6173 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6175 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6176 This produces more-accurate results.
6178 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6180 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6181 changes (Bug#12088).
6183 2012-09-08 Chong Yidong <cyd@gnu.org>
6185 * syntax.c (Fstring_to_syntax): Doc fix.
6187 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6189 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6190 in the internal border.
6191 (x_set_window_size): Remove static variables and their usage.
6192 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6193 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6194 Remove fringe/internal border adjustment (Bug#11052).
6195 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6196 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6197 (ns_fix_rect_ibw): Remove.
6198 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6199 (ns_dumpglyphs_box_or_relief): Ditto.
6200 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6202 (ns_dumpglyphs_image): Ditto.
6203 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6205 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6206 their usage. Add fringe_extended_p and its use as in other terms.
6207 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6208 scroll bar was removed.
6209 (updateFrameSize): New function.
6210 (windowDidResize): Move code to updateFrameSize and call it.
6212 * nsterm.h (EmacsView): Add updateFrameSize.
6214 2012-09-07 Chong Yidong <cyd@gnu.org>
6216 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6218 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6220 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6222 More signal-handler cleanup (Bug#12327).
6223 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6224 Problem introduced when merging patches. Noted by Eli Zaretskii in
6225 <http://bugs.gnu.org/12327#67>.
6226 * floatfns.c: Comment fix.
6227 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6228 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6229 and anyway the declaration is harmless even if SIGDANGER is not defined.
6230 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6231 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6232 source files not surprisingly expected syssignal.h to define, or
6233 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6234 Include <sys/ioctl.h>, for FIONREAD.
6235 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6236 This eliminates a problem whereby other files mysteriously had
6237 to include "syssignal.h" before including "systty.h" if they
6238 wanted to use "#ifdef SIGIO".
6240 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6242 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6244 * w32.c (sigemptyset): Empty the set.
6245 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6247 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6249 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6251 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6252 (mark_object): Likewise for frame objects.
6254 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6256 * syssignal.h (handle_on_main_thread): Always declare,
6257 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6258 This ports to platforms without HAVE_PTHREAD.
6260 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6262 Signal-handler cleanup (Bug#12327).
6263 Emacs's signal handlers were written in the old 4.2BSD style with
6264 sigblock and sigmask and so forth, and this led to some
6265 inefficiencies and confusion. Rewrite these to use
6266 pthread_sigmask etc. without copying signal sets around. Also,
6267 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6268 'signal', and instead use functions that do not attempt to take
6269 over the system name space. This patch causes Emacs's text
6270 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6271 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6272 Do not include <signal.h> or "syssignal.h", as these
6273 modules do not use signals.
6274 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6275 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6276 Do not include <signal.h>, as "syssignal.h" does that for us now.
6277 * atimer.c (sigmask_atimers): New function.
6278 (block_atimers, unblock_atimers): New functions,
6279 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6281 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6282 no longer needed here.
6283 * emacs.c (main): Inspect existing signal handler with sigaction,
6284 so that there's no need to block and unblock SIGHUP.
6285 * sysdep.c (struct save_signal): New member 'action', replacing
6286 old member 'handler'.
6287 (save_signal_handlers, restore_signal_handlers):
6288 Use sigaction instead of 'signal' to save and restore.
6289 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6290 New function. All users of 'signal' modified to use set_sighandler
6291 if they're writeonly, and to use sys_signal if they're read+write.
6292 (emacs_sigaction_init, forwarded_signal): New functions.
6293 (sys_signal): Remove. All uses replaced by calls to sigaction
6294 and emacs_sigaction_init, or by direct calls to 'signal'.
6295 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6296 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6297 all uses replaced by pthread_sigmask etc. calls.
6298 * syssignal.h: Include <signal.h>.
6299 (emacs_sigaction_init, forwarded_signal): New decls.
6300 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6301 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6302 (sigmask, sys_sigmask): Remove; no longer needed.
6303 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6304 (sigblock, sigunblock, sigfree):
6305 (sigsetmask) [!defined sigsetmask]:
6306 Remove. All uses replaced by pthread_sigmask.
6307 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6308 no longer need to be replaced, and its typical old uses
6309 are now done via emacs_sigaction_init and sigaction.
6310 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6311 (sys_sigdel): Remove; unused.
6312 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6314 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6316 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6317 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6319 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6321 Explicitly mark buffer_defaults and buffer_local_symbols.
6322 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6323 mark_local_symbols here.
6324 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6325 since special buffers aren't marked here any more.
6326 (allocate_buffer): Chain new buffer with all_buffers here...
6327 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6329 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6330 (syms_of_buffer): Remove staticpro of the above.
6331 (init_buffer_once): Set names for buffer_defaults and
6332 buffer_local_symbols.
6334 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6336 Use bool for booleans in font-related modules.
6337 * font.c (font_intern_prop, font_style_to_value)
6338 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6339 (generate_otf_features, font_check_otf_features, font_check_otf)
6340 (font_match_p, font_list_entities, font_at):
6341 * fontset.c (fontset_id_valid_p, reorder_font_vector
6342 (fontset_find_font, Fset_fontset_font)
6343 (face_suitable_for_char_p) [0]:
6344 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6345 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6346 (m17n_flt_initialized, ftfont_shape_by_flt):
6347 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6348 * nsfont.m (nsfont_draw):
6349 * w32font.c (w32font_draw):
6350 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6351 Use bool for booleans.
6352 * font.h: Adjust to above API changes.
6353 (struct font, struct font_driver, struct font_driver_list):
6354 Use bool for booleans.
6355 (struct font): Remove useless member encoding_type.
6357 * fontset.c, xftfont.c: Omit unnecessary static decls.
6359 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6361 * alloc.c (mark_object): Revert window marking code
6362 since it's unsafe for the Fset_window_configuration.
6364 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6366 Fix race conditions with signal handlers and errno (Bug#12327).
6367 Be more systematic about preserving errno whenever a signal
6368 handler returns, even if it's not in the main thread. Do this by
6369 renaming signal handlers to distinguish between signal delivery
6370 and signal handling. All uses changed.
6371 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6372 * data.c (deliver_arith_signal): Rename from arith_error.
6373 * dispnew.c (deliver_window_change_signal): Rename from
6374 window_change_signal.
6375 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6376 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6377 * keyboard.c (deliver_input_available_signal): Rename from
6378 input_available_signal.
6379 (deliver_user_signal): Rename from handle_user_signal.
6380 (deliver_interrupt_signal): Rename from interrupt_signal.
6381 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6382 (deliver_child_signal): Rename from sigchld_handler.
6383 * atimer.c (handle_alarm_signal):
6384 * data.c (handle_arith_signal):
6385 * dispnew.c (handle_window_change_signal):
6386 * emacs.c (handle_fatal_signal, handle_danger_signal):
6387 * keyboard.c (handle_input_available_signal):
6388 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6389 * process.c (handle_pipe_signal, handle_child_signal):
6390 New functions, with the actual signal-handling code taken from the
6391 original respective signal handlers, sans the sporadic attempts to
6392 preserve errno, since that's now done by handle_on_main_thread.
6393 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6394 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6395 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6397 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6398 Move initialization of main_thread to sysdep.c's init_signals.
6399 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6400 our usage, and simplifies the mainline code.
6401 (record_child_status_change): New static function, as a helper
6402 for handle_child_signal, and with most of the old child handler's
6404 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6405 (handle_child_signal): Use the above.
6406 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6407 Moved here from emacs.c.
6408 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6409 code moved here from emacs.c's main function.
6410 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6411 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6412 This lets callers save and restore errno properly.
6414 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6416 Remove redundant or unused things here and there.
6417 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6418 * conf_post.h (RE_TRANSLATE): Use char_table_translate.

6420 * frame.h (struct terminal, struct font_driver_list):
6421 Remove redundant declarations.
6422 * window.h (Qleft, Qright): Likewise.
6424 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6426 Do not mark objects from deleted buffers, windows and frames.
6427 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6428 (mark_object): Likewise for windows and frames.
6430 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6432 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6433 buffer_defaults and buffer_local_symbols as valid objects.
6434 Return special value to denote them.
6436 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6438 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6439 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6440 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6441 (file_name_absolute_p, Fsubstitute_in_file_name):
6442 (check_executable, check_writable, Ffile_accessible_directory_p)
6443 (Fset_file_selinux_context, Fdefault_file_modes)
6444 (Finsert_file_contents, choose_write_coding_system)
6445 (Fwrite_region, build_annotations, a_write, e_write)
6447 * filelock.c (boot_time_initialized, get_boot_time)
6448 (get_boot_time_1, lock_file_1, within_one_second):
6449 * floatfns.c (in_float):
6450 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6451 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6452 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6453 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6454 * window.c (compare_window_configurations):
6455 Use bool for booleans.
6456 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6457 (Fdefault_file_modes): Now mode_t, not int, for modes.
6458 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6459 (internal_delete_file): Now returns void, not a (boolean) int,
6460 since nobody was looking at the return value.
6461 * lisp.h, window.h: Adjust to above API changes.
6463 * xdisp.c (set_message): Simplify and reindent last change.
6465 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6467 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6469 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6471 * eval.c (call_debugger): Make the function non-static so that we
6472 can call it from set_message.
6474 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6475 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6477 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6479 Give more-useful info on a fatal error (Bug#12328).
6480 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6481 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6482 of doing the work ourselves.
6483 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6484 do most of the work.
6485 (fatal_error_backtrace): New function, taken from the guts
6486 of the old fatal_error_signal, but with a new option to output
6488 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6489 info about the signal than just its number.
6490 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6491 * sysdep.c: Include <execinfo.h>
6492 (emacs_backtrace): New function, taken partly from the previous
6493 code of the 'die' function.
6494 (emacs_abort): Call fatal_error_backtrace rather than abort.
6496 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6498 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6499 eager (load-time) macro-expansion.
6500 * lisp.mk (lisp): Add macroexp.
6502 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6504 Simplify redefinition of 'abort' (Bug#12316).
6505 Do not try to redefine the 'abort' function. Instead, redo
6506 the code so that it calls 'emacs_abort' rather than 'abort'.
6507 This removes the need for the NO_ABORT configure-time macro
6508 and makes it easier to change the abort code to do a backtrace.
6509 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6510 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6511 Remove; sysdep.c's emacs_abort now takes its place.
6512 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6513 'abort' changed to use 'emacs_abort'.
6514 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6515 (abort) [!defined abort]: Rename to ...
6516 (emacs_abort): ... new name.
6517 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6518 the place of the old 'abort' in emacs.c.
6519 * w32.c, w32fns.c (abort): Do not #undef.
6520 * w32.c (emacs_abort): Rename from w32_abort.
6522 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6524 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6525 offsets[j].dv, since the y axis of the screen coordinates points
6526 down, while the y axis of the font definition coordinates points
6527 up. This fixes display of Arabic diacritics such as KASRA and
6528 KASRATAN. (Bug#11860)
6530 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6532 Be more systematic about _setjmp vs setjmp.
6533 * alloc.c (test_setjmp, mark_stack):
6534 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6535 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6536 (png_load, my_error_exit, jpeg_load):
6537 * process.c (send_process_trap, send_process):
6538 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6539 The underscored versions are up to 30x faster on some hosts.
6540 Formerly, the code used setjmp+longjmp sometimes and
6541 _setjmp+_longjmp at other times, with no particular reason to
6542 prefer setjmp+longjmp.
6544 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6546 Fix minor problem found by static checking.
6547 * buffer.c (Fdelete_all_overlays): Return nil.
6549 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6551 * buffer.c (Fdelete_all_overlays): New function.
6553 2012-09-03 Chong Yidong <cyd@gnu.org>
6555 * gtkutil.c: Add extern decl for Qxft.
6557 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

6571 All callers changed.
6572 * eval.c (interactive_p): Omit always-true boolean argument
6573 EXCLUDE_SUBRS_P. All callers changed.
6574 * dispextern.h, lisp.h: Reflect above API changes.
6575 * firstfile.c (dummy): Use the address of 'main', whose signature
6576 won't change, instead of the address of 'initialize', whose
6577 signature just changed from int to bool.
6578 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6579 * msdos.c (fatal_error_in_progress): ... from here.
6580 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6582 (redisplay_internal, unwind_redisplay): Simply clear
6583 REDISPLAYING_P when unwinding, instead of saving its previous,
6584 always-false value and then restoring it.
6586 Clean up some extern decls.
6587 Mostly, this hoists extern decls out of .c files and into .h files.
6588 That way, we're more likely to catch errors if the interfaces change.
6589 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6590 declare xg_mark_data.
6591 * dispextern.h (x_frame_parm_handlers):
6593 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
6594 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)

6609 * xfont.c (x_clear_errors):
6610 * xterm.c (x_frame_parm_handlers):
6611 Remove now-redundant extern decls.
6612 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6613 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6615 * xfaces.c: Remove unnecessary static decls.
6616 * xterm.c (updating_frame): Remove decl of nonexistent object.
6618 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6619 when building globals.h, as the objects that are not built on
6620 this host are not needed to compile C files on this host.
6622 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6624 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

6637 (format_time_string, general_insert_function)
6638 (make_buffer_string, make_buffer_string_both)
6639 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
6640 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

6650 (get_property_and_range, compare_string_intervals)
6651 (set_intervals_multibyte_1, set_intervals_multibyte):
6652 * keyboard.c (decode_timer):
6653 Use bool for boolean.
6654 * intervals.h, lisp.h, systime.h: Reflect above API changes.
6655 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
6657 2012-09-02 Chong Yidong <cyd@gnu.org>
6659 * keymap.c (push_key_description): Print M-TAB as C-M-i
6662 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
6664 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
6665 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

6670 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
6672 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6674 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6675 more than one grapheme cluster passed to the shaper: compute the
6676 offset adjustment values separately for each cluster. (Bug#11860)
6678 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6679 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6680 about implicit conversions from integer to pointer.
6682 2012-09-01 Daniel Colascione <dancol@dancol.org>
6684 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6685 system used too early.
6687 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
6689 Better seed support for (random).
6690 * emacs.c (main): Call init_random.

6718 * process.c: Include TERM_HEADER instead of listing all possible
6719 window-system headers.
6721 * nsterm.h: Remove declarations now in frame.h.
6722 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
6724 * menu.c: Include TERM_HEADER instead of listing all possible
6725 window-system headers.
6727 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
6730 * keyboard.c: Include TERM_HEADER instead of listing all possible
6731 window-system headers.
6733 * image.c: Include TERM_HEADER instead of listing all possible
6734 window-system headers. Declare Vlibrary_cache when compiling for
6737 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
6738 window system declarations.
6740 * frame.h: Move common functions here: set_frame_menubar,
6741 x_set_window_size, x_sync, x_get_focus_frame,
6742 x_set_mouse_position, x_set_mouse_pixel_position,
6743 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6764 the current window system; include in list of objects to link into
6767 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6769 Remove mark_ttys function and fix tty_display_info initialization.
6770 * lisp.h (mark_ttys): Remove prototype.
6771 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
6772 to mark_ttys because all possible values of 'top_frame' slot are
6773 the frames which are reachable from Vframe_list.
6774 * term.c (mark_ttys): Remove.
6775 (init_tty): Safely initialize 'top_frame' slot with Qnil.
6777 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6779 Change struct frame bitfields from unsigned char to unsigned.
6780 * frame.h (struct frame): Change type of 'display_preempted',

6782 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
6783 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
6784 bitfields from unsigned char to unsigned.
6786 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6788 Remove unused member of struct x_output and struct w32_output.

6792 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
6794 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
6795 does not become zero (Bug#12234).
6797 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
6799 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6800 for GCC 4.7.1 x86-64.
6802 2012-08-30 Glenn Morris <rgm@gnu.org>
6804 * lread.c (init_lread): For out-of-tree builds, only add the
6805 source directory's site-lisp dir to the load-path if it exists,
6806 consistent with in-tree builds. (Bug#12302)
6808 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
6810 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
6811 button_values to NULL. Call setStykeMask so dialogs get a close button.
6812 (windowShouldClose:): Set window_closed.
6813 (dealloc): New member, free button_values.
6814 (process_dialog:): Make member function. Remove window argument,
6815 replace window with self. Count buttons and allocate and store values
6817 (addButton:value:row:): value is int with the name tag. Call setTag
6818 with tag. Remove return self, declare return value as void.
6819 (addString:row:): Remove return self, declare return value as void.
6820 (addSplit): Remove return self, declare return value as void.
6821 (clicked:): Remove return self, declare return value as void.
6822 Set dialog_return to button_values[seltag]. Code formatting change.
6823 (initFromContents:isQuestion:): Adjust call to process_dialog.
6824 Code formatting change.
6825 (timeout_handler:): Set timer_fired to YES.
6826 (runDialogAt:): Set timer_fired to NO.
6827 Handle click on close button as quit.
6829 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6830 Add window_closed and button_values. Add void as return value for
6831 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6832 Add process_dialog as new member.
6834 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6836 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
6837 is not one of the heaps we manage. (Bug#12242)
6839 2012-08-28 Glenn Morris <rgm@gnu.org>
6841 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
6843 2012-08-28 Martin Rudalics <rudalics@gmx.at>

6897 (change_frame_size_1, sit_for):
6898 Use bool for boolean.
6899 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
6900 and remove last int (actually boolean) argument, which was always 0.
6901 All callers changed.
6902 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
6903 * dispextern.h (struct composition_it): Use bool for boolean.
6904 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
6905 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
6906 * dired.c (file_name_completion):
6907 Use bool for boolean. (This was missed in an earlier change.)
6909 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6911 * window.c (Fset_window_configuration): Revert first part of
6914 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
6916 * nsterm.h (NSPanel): New class variable dialog_return.
6918 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
6919 Initialize dialog_return.
6920 (windowShouldClose:): Use stop instead of stopModalWithCode.
6921 (clicked:): Ditto, and also set dialog_return (Bug#12258).
6922 (timeout_handler:): Use stop instead of abortModal. Send a dummy
6924 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

6969 Use bool for booleans.
6970 * coding.h, lisp.h: Reflect above API changes.
6971 * coding.c: Remove unnecessary static function decls.
6972 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6973 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6974 not a boolean 'int', since callers never look at the return value.
6975 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
6976 * coding.h (decoding_buffer_size, encoding_buffer_size)
6977 (emacs_mule_string_char): Remove unused extern decls.
6978 (struct iso_2022_spec, struct coding_system):

6980 (struct emacs_mule_spec): Remove unused field 'full_support'.
6981 All initializations removed.
6982 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
6984 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6986 Fix spare memory change (Bug#12286).
6987 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
6988 (valid_lisp_object_p): Likewise.
6990 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6992 * window.c (Fset_window_configuration): Record any window's old
6993 buffer if it's replaced (see Bug#8789). If the new current
6994 buffer doesn't appear in the selected window, go to its old
6997 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6999 Special MEM_TYPE_SPARE to denote reserved memory.
7000 * alloc.c (enum mem_type): New memory type.
7001 (refill_memory_reserve): Use new type for spare memory.
7002 This prevents live_cons_p and live_string_p from incorrect
7003 detection of uninitialized objects from spare memory as live.
7005 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7008 * Makefile.in (.PHONY): versioclean -> versionclean.
7010 Remove unused external symbols.
7011 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7012 * window.c (Qwindow_valid_p, decode_valid_window):
7013 Now static, not extern.
7014 * data.c (Qinterval): Remove; unused.
7015 (syms_of_data): Do not define 'interval'.
7016 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7017 * window.h (decode_valid_window):
7020 * character.c, charset.c, chartab.c: Use bool for booleans.

7030 (char_table_set_range, optimize_sub_char_table)
7031 (map_sub_char_table):
7032 Use bool for boolean.
7033 * character.c (str_to_unibyte): Omit last boolean argument; it was
7034 always 0. All callers changed.
7035 * character.h, charset.h: Adjust to match previous changes.
7036 * character.h (char_printable_p): Remove decl of nonexistent function.
7037 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7038 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7039 are all boolean, so make them single-bit bitfields.
7041 * lisp.h (ASET): Remove attempt to detect side effects.
7042 It was meant to be temporary and it often doesn't work,
7043 because when IDX has side effects the behavior of IDX==IDX
7044 is undefined. See Stefan Monnier in
7045 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7047 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7049 * lisp.h (functionp): New function (extracted from Ffunctionp).
7050 (FUNCTIONP): Use it.
7051 * eval.c (Ffunctionp): Use it.
7053 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7055 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7056 as that's faster and simpler than static storage. Don't bother
7057 with the g_main_context_query overhead if g_main_context_pending
7058 says no events are pending.
7059 (gfds, gfds_size): Remove these static vars.
7060 (xgselect_initialize): Remove; no longer needed.
7061 All uses and decls removed.
7063 * emacs.c (fatal_error_signal_hook): Remove.
7064 All uses removed. This leftover from old code was always 0.
7066 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7067 * casefiddle.c (casify_object, casify_region):
7068 * casetab.c (set_case_table):
7069 * category.c, category.h (word_boundary_p):
7070 * category.h (CHAR_HAS_CATEGORY):
7071 Use bool for booleans, instead of int.
7073 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7075 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7077 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7079 On assertion failure, print backtrace if available.
7080 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7081 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7082 * Makefile.in (LIB_EXECINFO): New macro.
7085 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7086 * bytecode.c (exec_byte_code):
7087 * callint.c (check_mark, Fcall_interactively):
7088 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7089 (getenv_internal, sync_process_alive, call_process_exited):
7090 * lisp.h (USE_SAFE_ALLOCA):
7091 Use bool for booleans, instead of int.
7092 * lisp.h, process.h: Adjust prototypes to match above changes.
7093 * callint.c (Fcall_interactively): Don't assume the mark's
7094 offset fits in 'int'.
7096 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7098 * buffer.c, buffer.h: Use bool for boolean.
7099 * buffer.c (reset_buffer_local_variables)
7100 (buffer_lisp_local_variables, Fset_buffer_modified_p)

7104 (report_overlay_modification, call_overlay_mod_hooks):
7105 (mmap_enlarge, mmap_set_vars):
7106 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7107 Use bool for booleans, instead of int.
7108 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7109 since the 1-or-0 return value is always ignored anyway.
7110 (mmap_initialized_p):
7111 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7112 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7114 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7116 * bidi.c: Use bool for boolean.
7117 This is a bit more readable, and makes the text segment of bidi.o
7118 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7119 Presumably it's faster too.
7120 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7122 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7123 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7124 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7125 (bidi_explicit_dir_char, bidi_level_of_next_char)
7126 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7127 Use bool for booleans, instead of int.
7128 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7129 (bidi_unshelve_cache): Adjust decls to match code.
7131 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7133 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7136 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7138 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7139 * atimer.h: Include <stdbool.h>.
7141 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7143 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7144 compile time tests instead of run time tests on systems that do
7146 (FRAME_MAC_P): Remove leftover from deleted code.
7147 * frame.c (syms_of_frame): Remove leftover from deleted code.
7149 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7151 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7153 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7155 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7156 Otherwise, the compiler complains about (A?B:C) where B is void
7157 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7158 (fontset_add): Return void, for FONTSET_ADD.
7160 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7162 * alloc.c: Use bool for booleans.
7163 (gc_in_progress, abort_on_gc)
7164 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7165 (dont_register_blocks) [GC_MALLOC_CHECK]:
7166 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7167 (check_string_bytes, make_specified_string, memory_full)
7168 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7169 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7170 (mark_stack, valid_pointer_p, make_pure_string)
7171 (Fgarbage_collect, survives_gc_p, gc_sweep):
7172 Use bool for booleans, instead of int.
7173 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7174 Remove unused local.
7175 * alloc.c (PURE_POINTER_P):
7176 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7177 * editfns.c (Fformat):
7178 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7180 * fns.c (sweep_weak_table):
7181 * lisp.h (suppress_checking, push_message, survives_gc_p)
7182 (make_pure_string, gc_in_progress, abort_on_gc):
7183 * lread.c (readchar, read1):
7184 * print.c (Fprin1_to_string):
7185 * xdisp.c (push_message):
7186 Use bool for booleans affected directly or indirectly by
7189 Make recently-introduced setters macros.
7190 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7191 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7192 (set_fontset_default, set_fontset_fallback): Rename from their
7193 upper-case counterparts, and make them functions rather than macros.
7194 This is more consistent with the other recently-introduced setters.
7195 These don't need to be inline, since they're local.
7197 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7199 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7200 the loop (Bug#12247).
7202 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7204 * lisp.h (vcopy): Use memcpy rather than our own loop.
7205 This fixes a performance regression introduced by the recent
7206 addition of vcopy. This means 'vcopy' will need to be modified
7207 for a copying collector, but that's OK. Also, tighten the
7208 checking in the assertion.
7210 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7212 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7213 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7214 non-base glyph for the width of the base character, according to
7215 what x_draw_composite_glyph_string_foreground expects.
7216 Generate WADJUST value according to composition_gstring_width's
7217 expectations, to produce correct width of the composed character.
7218 Reverse the sign of the DU offset produced by ScriptPlace.
7220 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7222 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7224 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7226 Avoid direct writes to contents member of struct Lisp_Vector.
7227 * lisp.h (vcopy): New function to copy data into vector.
7228 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7229 * fns.c (Ffillarray): Use ASET.
7230 * keyboard.c (timer_check_2): Use AREF and ASET.
7231 (append_tool_bar_item, Frecent_keys): Use vcopy.
7232 * lread.c (read_vector): Use ASET.
7233 * msdos.c (Frecent_doskeys): Use vcopy.
7234 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7235 (Finternal_merge_in_global_face): Use ASET and vcopy.
7236 * xfont.c (xfont_list_pattern): Likewise.
7238 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7240 * window.c (Fwindow_point): For the selected window always return
7241 the position of its buffer's point.
7242 (Fset_window_point): For the selected window always go in its
7243 buffer to the specified position.
7245 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7247 Setter macros for fontsets.
7248 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7249 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7250 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7253 2012-08-20 Glenn Morris <rgm@gnu.org>
7255 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7256 Don't assume that `ln -f' works.
7258 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7260 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7261 and later about non-assignments with no effect. See discussion at
7262 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7265 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7267 Inline setter functions for Lisp_Objects slots of struct specbinding.
7268 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7271 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7273 * window.c (select_window): Always make selected window's buffer
7276 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7278 Use AREF and ASET for docstrings of category tables.
7279 * category.h (CATEGORY_DOCSTRING): Use AREF.
7280 (SET_CATEGORY_DOCSTRING): Use ASET.
7281 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7283 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7285 Inline setter functions for hash table members.
7286 * lisp.h (set_hash_key, set_hash_value, set_hash_next)

7304 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7306 Rely on <config.h> + <unistd.h> to declare 'environ',
7307 as gnulib does this if the system doesn't.
7308 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

8177 2012-08-04 Eli Zaretskii <eliz@gnu.org>
8179 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
8180 * w32.c (init_environment): Change the default values of many
8181 environment variables in dflt_envvars[] to NULL, to avoid pushing
8182 them into environment when they were not already defined.
8183 Remove the code that deletes site-lisp subdirectories from the default
8184 value of EMACSLOADPATH, as it is no longer needed.
8185 (check_windows_init_file): Now external, not static.
8186 Use Vload_path as is, without adding anything, as this function is now
8187 called when Vload_path is already set up.
8189 * w32.h (check_windows_init_file): Add prototype.
8191 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
8192 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
8193 compatibility with Posix platforms.
8194 (main): Move the call to check_windows_init_file to here from
8196 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
8197 any, in the DEFALT argument into the root of the Emacs build or
8198 installation tree, as appropriate.
8200 * callproc.c (init_callproc_1): Call decode_env_path instead of
8201 doing its equivalent by hand.
8202 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
8203 the code that sets Vexec_path run on MS-Windows.
8205 * lread.c (init_lread): Add comments to #ifdef's.
8207 * msdos.c (dos_set_window_size, IT_update_begin)
8208 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
8209 instead of direct references.
8211 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
8213 Export DEFAULT_REHASH_* to GDB.
8214 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
8215 Now constants, not macros.
8217 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
8219 Remove unnecessary casts involving pointers.
8220 These casts are no longer needed now that we assume C89 or later,
8221 since they involve casting to or from void *.
8222 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
8223 (make_pure_float, make_pure_vector):
8224 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

8233 (x_get_window_property, x_get_window_property_as_lisp_data):
8234 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8235 Remove unnecessary pointer casts.
8236 * alloc.c (record_xmalloc): New function.
8237 * lisp.h (record_xmalloc): New decl.
8238 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8239 more like a function. This is because the pointer cast is not
8240 needed. All uses changed.
8241 * print.c (print_string, print_error_message): Avoid length recalc.
8243 Improve fix for macroexp crash with debugging (Bug#12118).
8244 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8245 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8246 not supposed to be invoked from the garbage collector.
8247 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
8248 (gc_aset): New function, which is like ASET but can be
8249 used in the garbage collector.
8250 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
8251 (set_hash_index): Use it instead of ASET.

8260 <g_b_init_create_symbolic_link>: New static flags.
8261 (globals_of_w32): Initialize them to zero.
8262 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
8263 (map_w32_filename): Improve commentary. Simplify switch.
8264 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
8265 headers (most versions of MinGW w32api don't).
8266 (get_security_info, create_symbolic_link)
8267 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
8269 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
8270 in the argument file name.
8271 (sys_access): Call unc_volume_file_attributes only if

8273 (sys_rename): Diagnose renaming of a symlink when the user doesn't
8274 have the required privileges.
8275 (get_file_security_desc_by_name): Rename from
8276 get_file_security_desc.
8277 (stat_worker): New function, with most of the guts of 'stat', and
8278 with addition of handling of symlinks and support for 'lstat'.
8279 If possible, get file's attributes and security information by
8280 handle, not by name. Produce S_IFLNK bit for symlinks, when
8281 called from 'lstat'.
8282 (stat, lstat): New functions, call 'stat_worker'.
8283 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8284 symlinks when the underlying filesystem supports them.
8286 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8288 Fix macroexp crash on Windows with debugging (Bug#12118).
8289 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8290 checking subscripts; problem introduced with the recent
8291 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8292 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8293 since it's used in non-static inline functions now.
8295 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8296 Don't assume buffer size fits in 'int'. Remove unused local.
8298 Use C99-style 'extern inline' if available.

8300 * category.h (CATEGORY_INLINE):
8301 * character.h (CHARACTER_INLINE):

8310 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
8311 * alloc.c (LISP_INLINE):
8312 * buffer.c (BUFFER_INLINE):
8313 * category.c (CATEGORY_INLINE):
8314 * character.c (CHARACTER_INLINE):
8315 * charset.c (CHARSET_INLINE):
8316 * composite.c (COMPOSITE_INLINE):
8317 * dispnew.c (DISPEXTERN_INLINE):
8318 * sysdep.c (SYSTIME_INLINE):
8319 Define to EXTERN_INLINE, so that the corresponding functions
8320 are compiled into code.
8321 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8322 (INLINE_HEADER_END): New macros.
8323 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8343 hard-coding the path separator.
8345 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8347 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8348 This how ASET and AREF are supposed to work, and makes
8349 it easier to think about future improvements. See
8350 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8351 * charset.h (set_charset_attr): New function.
8352 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
8353 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

8732 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
8733 (w32_kbd_patch_key, key_event): Use the codepage returned by
8734 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

8766 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
8767 enumeration constants, as PURE and HEAP are too general, and clash
8768 with other headers and sources, such as gmalloc.c and the
8769 MS-Windows system headers. All users changed.
8771 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8773 Revert last save_excursion_save and save_excursion_restore changes.
8774 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

8787 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8788 arms of an 'if', not using conditional expressions; otherwise GDB
8789 complains about the types in the unevaluated arm when the argument
8790 is an integer literal.
8791 (xgetint): Simplify expression.
8792 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8793 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8794 Zaretskii in <http://bugs.gnu.org/12036#13>.
8795 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8796 needed now that we have gdb_make_enums_visible.
8797 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8798 (enum enum_USE_LSB_TAG):
8799 New enum types, packaging up enums that need to be exported to GDB.

8824 (PVEC_EXCURSION): New pseudovector type.
8825 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8826 to deal with it. Adjust comments.

8841 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8842 emacs.c, as this is a more-suitable home. Had this been done earlier
8843 the fix for 12036 would have avoided some of the problems noted in
8844 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8845 would have been more obvious.
8846 * emacs.c: Do not include <verify.h>; no longer needed.
8847 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8848 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8849 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

8855 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8856 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8857 not be usable in #if. This simplifies things.
8859 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8861 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

8866 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8867 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8868 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8869 Adjust to changes in lisp.h and emacs.c, by using
8870 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8871 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8872 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8873 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8874 instead of gdb_valbits.
8875 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8876 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8877 instead of gdb_array_mark_flag.
8878 (xboolvector): Get size from $->size, not $->header.size.
8879 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8880 (xreload, hook-run, hookpost-run): Remove.
8881 * emacs.c: Include <verify.h>.
8882 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8883 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8885 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8886 (gdb_USE_LSB_TAG): New enum constants.
8887 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8888 Also define these as enum constants, so they're visible to GDB.
8889 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8890 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8891 as constants, so they're visible to GDB.

8894 Now enum constants, not macros, so they're visible to GDB.
8895 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8896 more convenient now. All uses changed.
8897 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8898 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8900 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8905 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
8907 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8908 add argument, tune behavior, and adjust all callers.
8910 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8912 Use typedef for EMACS_INT, EMACS_UINT.
8913 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8914 than macros. This simplifies debugging in the usual case, since
8915 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8916 and it allows expressions involving EMACS_INT casts.
8917 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8919 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8929 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8931 Adjust buffer text indirection counters at the end of Fkill_buffer.
8932 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8933 buffer is definitely dead. This should really fix an issue reported
8934 by Christoph Scholtes again. (Bug#12007).
8935 (init_buffer_once): Initialize indirection counters of
8936 buffer_defaults and buffer_local_symbols (for sanity and safety).
8938 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8940 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8941 and continuation glyphs on tooltip frames, leave them at zero.

8969 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8971 Swap buffer text indirection counters in Fbuffer_swap_text.
8972 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8973 This avoids crash reported by Christoph Scholtes at
8974 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8976 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8978 * nsmenu.m (Popdown_data): New struct.
8979 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8981 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
8982 (initWithContentRect): Make imgView and contentView non-static
8983 and autorelease them. Also autorelease img and matrix (Bug#12005).
8984 (dealloc): Remove (Bug#12005).
8986 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
8988 Adjust consing_since_gc when objects are explicitly freed.

8997 (live_buffer, set_marker_internal): New function.
8998 (Fset_marker, set_marker_restricted): Use set_marker_internal.

9001 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9003 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9004 as it's limited by the amount of memory, not by INT_MAX.
9006 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9008 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9009 in special-event-map. See the discussion at

9732 * s/aix4-2.h (unix): Remove; no longer needed.
9734 EMACS_TIME simplification (Bug#11875).
9735 This replaces macros (which typically do not work in GDB)
9736 with functions, typedefs and enums, making the code easier to debug.
9737 The functional style also makes code easier to read and maintain.
9738 * systime.h: Include <sys/time.h> on all hosts, not just if
9739 WINDOWSNT, since 'struct timeval' is needed in general.

9752 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9753 not functions. All uses rewritten to use the following, respectively:
9754 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9755 (add_emacs_time, sub_emacs_time): New functions.
9756 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

9779 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9780 Prefer snprintf to strncpy.
9781 * nsterm.m (ns_term_init):
9782 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9783 * nsterm.m (ns_term_init):
9784 Avoid the need for strncpy, by using build_string or
9785 make_unibyte_string directly. Use dtoastr, not snprintf.
9786 * process.c (Fmake_network_process): Diagnose service names that
9787 are too long, rather than silently truncating them or creating
9788 non-null-terminated names.
9789 (Fnetwork_interface_info): Likewise, for interface names.
9790 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9791 Prefer sprintf to strncat.

9798 Clarify fallback case.
9800 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

9805 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9806 where argument type is known to be a Lisp_Cons.

9861 O_RDONLY already includes it).
9863 Stop ns builds setting the EMACSLOADPATH environment variable.
9864 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9865 Now it does not set EMACSLOADPATH, just returns the load-path string.

9867 * lread.c [HAVE_NS]: Include nsterm.h.
9868 (init_lread) [HAVE_NS]: Use ns_load_path.

9878 (ns_init_paths): Do not set EMACSPATH.

9936 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9938 Move marker debugging code under MARKER_DEBUG.
9939 * marker.c (MARKER_DEBUG): Move marker debugging code under
9940 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9941 for bootstrap with --enable-checking (~3x slowdown reported
9942 by Juanma Barranquero <lekktu@gmail.com>).
9943 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9945 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9947 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9948 See <http://bugs.gnu.org/11825#29>.
9950 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9952 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9953 has no font, use the frame's font. (Bug#11813)
9954 (display_line): Add commentary about displaying truncation glyphs
9956 (produce_special_glyphs): Move here from term.c.
9958 * term.c (produce_special_glyphs): Move to xdisp.c.
9960 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9963 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9965 * xdisp.c (display_line): Avoid warning about implicit declaration
9968 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9970 * lisp.h: Remove empty conditional.
9972 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9974 * lread.c (load_path_check): Now static.
9976 Fix some minor --with-ns problems found by static checking.
9977 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9978 (x_set_font) [!HAVE_X_WINDOWS]:
9979 * image.c (xpm_load_image) [HAVE_NS]:
9980 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9981 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9982 Remove unused local.
9983 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9984 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9985 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9986 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9987 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9988 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9989 Fix pointer signedness problem.
9990 * xfaces.c (FRAME_X_FONT_TABLE):
9991 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9993 2012-07-07 Glenn Morris <rgm@gnu.org>
9995 * lread.c (load_path_check): New function, split from init_lread.
9996 (init_lread): Reorganize. Motivation:
9997 If EMACSLOADPATH is set, check/warn about that rather than the
9998 defaults, which we are not going to use. Hence we can remove
9999 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10000 Don't warn if site-lisp directories are missing.
10001 If not installed, start from a blank load-path, since
10002 PATH_LOADSEARCH refers to the eventual installation directories.
10004 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10006 Support truncation and continuation glyphs on GUI frames, when
10007 fringes are disabled. (Bug#11832)
10008 * xdisp.c (init_iterator): Get dimensions of truncation and
10009 continuation glyphs even if on GUI frames.
10010 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10011 or both, are absent.
10012 (start_display, move_it_in_display_line_to): Handle the case of a
10013 GUI frame without a fringe to display continuation or truncation
10015 (insert_left_trunc_glyphs): Support GUI frames: make sure
10016 truncation glyphs overwrite enough glyphs from the current line to
10017 have sufficient space in pixels.
10018 (display_line): Support truncation and continuation glyphs on GUI
10019 frames. If some spare pixels are left on the line after inserting
10020 the truncation glyphs, fill that space with a stretch glyph of a
10021 suitably computed width.
10023 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10024 produce_glyphs, to support GUI sessions.
10026 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10028 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10030 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10032 Do not require float-time's arg to fit in time_t (Bug#11825).
10033 This works better on hosts where time_t is unsigned, and where
10034 float-time is applied to the (negative) difference between two times.
10035 * editfns.c (decode_time_components): Last arg is now double *,
10036 not int *, and means to store all the result as a double, without
10037 worrying about whether the seconds part fits in time_t.
10038 All callers changed.
10039 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10040 All callers changed.
10041 (Ffloat_time): Do not fail merely because the specified time falls
10042 outside of time_t range.
10044 2012-07-07 Glenn Morris <rgm@gnu.org>
10046 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10047 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10048 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10050 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10052 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10053 Update dependencies.
10055 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10057 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

10061 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10062 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10063 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10064 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10066 * xfont.c (compare_font_names): Redo to omit the need for casts.
10068 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10070 * xfns.c (Fx_change_window_property): Doc fix.
10071 * w32fns.c (Fx_change_window_property): Doc fix.
10073 * w32fns.c (Fx_window_property): Accept the same arguments as the
10074 X Windows version. Doc fix.
10075 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10077 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10078 Eli Zaretskii <eliz@gnu.org>
10080 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10081 Windows-specific code from nt/config.nt moved here.
10082 Obsolete settings removed.
10084 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10086 * process.c: Avoid unnecessary calls to gettime.
10087 (wait_reading_process_output): Don't get the time of day
10088 when gobbling data immediately and not waiting, as there's no need
10089 for it in that case. This removes a FIXME.
10091 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10093 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10094 is defined (Bug#11768).
10096 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10098 Fix marker debugging code.
10099 * marker.c (byte_char_debug_check): Do not perform the check
10100 if buffer is not multibyte.
10101 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10102 Call byte_char_debug_check with correct arguments.
10104 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10106 Compile marker debugging code only if ENABLE_CHECKING is defined.
10107 * marker.c (byte_char_debug_check, count_markers):
10108 Use only if ENABLE_CHECKING is defined.
10109 (byte_debug_flag): Remove.
10110 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10111 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10113 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10115 Avoid code repetition in marker-related functions.
10116 * marker.c (attach_marker): New function.
10117 (Fset_marker, set_marker_restricted, set_marker_both)
10118 (set_marker_restricted_both): Use it.
10119 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
10120 Consistently rename charno to charpos.
10121 (marker_position): Add eassert.
10122 (marker_byte_position): Convert to eassert.
10124 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10126 Simplify list operations in unchain_overlay and unchain_marker.

10128 * marker.c (unchain_marker): Simplify. Fix comments.
10130 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

10136 * composite.c (autocmp_chars): Likewise.
10137 * editfns.c (buildmark): Remove.
10138 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10139 (save_restriction_save): Use build_marker.
10140 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10141 * window.c (save_window_save): Likewise.
10143 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10145 Do not use Fdelete_overlay in delete_all_overlays
10146 to avoid redundant calls to unchain_overlay.
10147 * buffer.c (drop_overlay): New function.
10148 (delete_all_overlays, Fdelete_overlay): Use it.
10149 * minibuf.c (get_minibuffer): Fix comment.
10151 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10153 Port to OpenBSD 5.1 amd64.
10154 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10155 This is needed for OpenBSD, and should be harmless on all BSD systems.
10156 Also, include <sys/sysctl.h>, as it should be available on all
10157 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10158 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10159 use p_pid member, not kp_proc.pid.
10161 2012-07-06 Glenn Morris <rgm@gnu.org>
10163 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10165 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10167 More xmalloc and related cleanup.
10168 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
10169 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
10170 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

10176 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10178 Omit needless casts involving void * pointers and allocation.
10179 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10180 as the former is more robust if P's type is changed.
10181 Prefer xzalloc to xmalloc + memset 0.
10182 Simplify malloc-or-realloc to realloc.
10183 Don't worry about xmalloc returning a null pointer.
10184 Prefer xstrdup to xmalloc + strcpy.
10185 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10187 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10188 alloca of a constant.
10190 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10192 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10193 hscroll is larger than the line width. Fixes long and futile
10194 looping inside extend_face_to_end_of_line (on a TTY) producing
10195 glyphs that are not needed and thrown away.
10197 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10199 * marker.c (set_marker_restricted_both): Simplify by using
10202 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10204 * editfns.c (region_limit): Simplify by using clip_to_bounds.

10212 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
10213 followed by gtk_box_set_homogeneous (Bug#11768).
10214 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10215 (update_theme_scrollbar_width, xg_create_scroll_bar):
10216 Use gtk_scrollbar_new (Bug#11768).
10217 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
10218 (is_box_type): New function (Bug#11768).
10219 (xg_tool_item_stale_p): Call is_box_type.
10220 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10221 with default display (Bug#11768).
10223 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10225 * xdisp.c (window_hscroll_limited): New function.
10226 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10227 coordinates when window's hscroll is set to insanely large
10228 values. (Bug#11857)
10230 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
10232 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

10291 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10293 * fileio.c (time_error_value): Check the right error number.
10294 Problem reported by Troels Nielsen in
10295 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10297 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10299 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10300 This should be fixed in a better way; see Eli Zaretskii in
10301 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10302 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10304 * fileio.c (time_error_value): Rename from special_mtime.
10305 The old name's problems were noted by Eli Zaretskii in
10306 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10308 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10309 This variable's comment says Emacs needs at least one GDB-visible
10310 symbol of type enum pvec_type, to work around GDB problems.
10311 The symbol's value doesn't matter.
10313 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10314 that causes compilation to fail on pre-C99 compilers.
10316 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10318 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10319 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10321 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10323 * buffer.c (init_buffer_once): Fix initialization of
10324 headers for buffer_defaults and buffer_local_symbols.
10325 Reported by Juanma Barranquero <lekktu@gmail.com>.
10327 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10329 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10330 * lisp.h (enum pvec_type): Use fewer bits.
10331 (PSEUDOVECTOR_SIZE_BITS): New constant.
10332 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10333 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10334 change in pvec_type.
10335 (PSEUDOVECTOR_TYPEP): New macro.
10336 (TYPED_PSEUDOVECTORP): Use it.
10337 * fns.c (internal_equal): Adapt code to extract pvectype.

10339 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10340 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10341 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10342 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10343 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10344 abusing vector->header.next.nbytes.
10345 (live_vector_p): Use PVEC_TYPE.
10346 (mark_object): Adapt code to extract pvectype. Use switch.
10348 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10350 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10351 Tighten new eassert a bit.
10353 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10355 Fix compilation with --enable-gcc-warnings and -O1
10356 optimization level.
10357 * doprnt.c (doprnt): Change type of tem to int, initialize
10358 to avoid compiler warning. Add eassert.
10359 * search.c (simple_search): Initialize match_byte to avoid
10360 compiler warning. Add eassert.
10362 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10364 Avoid weird behavior with large horizontal scrolls.
10365 Without this change, for example, large hscroll values would
10366 mess up Emacs's display on Fedora 15 x86, presumably due to
10367 overflows in int calculations in the display code.
10368 Also, if buffers had long lines, Emacs would freeze.
10369 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10370 (set_window_hscroll): New function, containing the old guts of
10371 Fset_window_hscroll. Return the clipped value.
10372 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10373 This avoids the need to check against PTRDIFF_MAX.
10375 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10377 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10379 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10381 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10383 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10384 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10385 since GCC 4.4.6 issues a bogus warning for them.
10387 Fix bugs in file timestamp newness comparisons.
10388 * fileio.c (Ffile_newer_than_file_p):
10389 * lread.c (Fload): Use full timestamp resolution of files,
10390 not just the 1-second resolution, so that files that are only
10391 slightly newer still count as newer.
10392 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10393 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10395 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10397 * fileio.c: Improve handling of file time marker. (Bug#11852)
10398 (special_mtime): New function.
10399 (Finsert_file_contents, Fverify_visited_file_modtime):
10400 Use it to set special mtime values consistently.
10402 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10404 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10405 marker for non-existing file. (Bug#11852)
10407 2012-07-03 Glenn Morris <rgm@gnu.org>
10409 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10410 and did not make it into globals.h).
10412 2012-07-03 Tom Tromey <tromey@redhat.com>
10414 * window.c (Fset_window_margins, Fset_window_fringes)
10415 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10416 * textprop.c (Fprevious_property_change): No longer static.
10417 * syntax.c (Fsyntax_table_p): No longer static.
10418 * process.c (Fget_process, Fprocess_datagram_address): No longer
10420 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
10421 * keyboard.c (Fcommand_execute): No longer static.

10439 * intervals.h: Remove EXFUNs.
10440 * fontset.h: Remove EXFUN.
10441 * font.h: Remove EXFUNs.
10442 * dosfns.c (system_process_attributes): Remove EXFUN.
10443 * keymap.h: Remove EXFUNs.
10444 * lisp.h: Remove EXFUNs.
10445 * w32term.h: Remove EXFUNs.
10446 * window.h: Remove EXFUNs.
10447 * xsettings.h: Remove EXFUN.
10448 * xterm.h: Remove EXFUN.
10450 2012-07-03 Glenn Morris <rgm@gnu.org>
10452 * lisp.h (Frandom): Make it visible to C.
10453 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10454 buffer for invisible buffers. (Bug#1229)
10456 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10458 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10459 values which aren't power of 2.
10460 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10461 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10464 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10466 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10468 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10470 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10472 * alloc.c (allocate_vector_block): Remove redundant
10473 calls to mallopt if DOUG_LEA_MALLOC is defined.
10474 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10475 avoid calls to mallopt if zero_vector is returned.
10477 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10479 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10480 is enabled, avoid dereferencing NULL current_sblock if
10483 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10485 Cleanup basic buffer management.
10486 * buffer.h (struct buffer): Change layout to use generic vector
10487 marking code. Fix some comments. Change type of 'clip_changed'
10488 to bitfield. Remove unused #ifndef old.
10489 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10490 (GET_OVERLAYS_AT): Fix indentation.
10491 (for_each_per_buffer_object_at): New macro.
10492 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10493 (Fbuffer_local_variables): Use it.
10494 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
10495 * alloc.c (allocate_buffer): Adjust to match new layout of
10496 struct buffer. Fix comment.
10497 (mark_overlay): New function.
10498 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10499 Lisp area of struct buffer.
10500 (mark_object): Use it. Adjust marking of misc objects
10501 and related comments.
10503 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10505 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10506 wrapper that is not needed because the wrapped code is a no-op (zero
10507 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10508 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10510 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10512 * alloc.c (mark_buffer): Simplify. Remove prototype.
10513 (mark_object): Add comment. Reorganize marking of vector-like
10514 objects. Use CHECK_LIVE for all vector-like objects except buffers
10515 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10516 Avoid redundant calls to mark_vectorlike for bool vectors.
10518 2012-06-30 Glenn Morris <rgm@gnu.org>
10520 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10522 * epaths.in (PATH_SITELOADSEARCH): New.
10523 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10524 This is rather than relying on --enable-locallisppath elements
10525 having "site-lisp" in their names. (Bug#10208#25, 11658)
10527 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10529 * w32proc.c (sys_select): Accept and ignore one more argument.
10531 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10533 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10534 (pselect) [!MS_DOS]: Redirect to sys_select.
10536 * sysdep.c: Don't include dos.h and dosfns.h.
10538 * process.c (sys_select):
10539 * msdos.c (sys_select): Accept one more argument and ignore it.
10541 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10542 adapt data types and code to that.
10545 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10546 which clashes with the gnulib function of the same name.
10548 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10550 * font.c (font_style_to_value, font_style_symbolic)
10551 (font_prop_validate_style): Add type checks for values in
10554 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10556 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10559 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10561 * xdisp.c (try_window_id): Undo last change.
10563 * w32.c (getwd): Adjust commentary about startup_dir.
10564 (init_environment): Always call sys_access, even in non-MSVC
10565 builds. Don't chdir to the directory of the Emacs executable.
10566 This undoes code from 1997 which was justified by the need to
10567 "avoid conflicts when removing and renaming directories". But its
10568 downside was that every relative file name was being interpreted
10569 relative to the directory of the Emacs executable, which can never
10570 be TRT. In particular, it broke sys_access when called with
10571 relative file names.
10572 (sys_access): Map GetLastError to errno.
10574 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10576 * window.h (struct window): Change type of 'fringes_outside_margins'
10577 to bitfield. Fix comment. Adjust users accordingly.
10578 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10580 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10583 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10585 * gnutls.c (emacs_gnutls_handshake):
10586 Add QUIT to make the loop interruptible.
10588 2012-06-29 Glenn Morris <rgm@gnu.org>
10590 * charset.c (init_charset): Make lack of etc/charsets fatal.
10592 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10594 * editfns.c (region_limit): Fix type mismatch.
10596 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10598 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10599 undefined. Convert from xassert to eassert.
10600 * nsmenu.m: Convert from xassert to eassert.
10601 * nsterm.m: Likewise.
10603 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

10607 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10609 Avoid integer overflow on scroll-left and scroll-right.
10610 * window.c (HSCROLL_MAX): New macro.
10611 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10612 overflow when requested scroll falls outside ptrdiff_t range.
10614 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10616 * window.h (struct window): Change type of 'hscroll',
10617 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10618 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10619 Adjust users accordingly.
10620 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10621 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10622 from EMACS_INT to ptrdiff_t.
10623 (make_window): Omit redundant initialization.

10641 enabled with --enable-checking=[all,glyphs] configure option.
10642 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10643 adjust comments accordingly.

10645 undefined, adjust comments accordingly.

10692 * alloc.c (allocate_string_data): Remove dead code.
10693 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to

10696 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
10698 * alloc.c (allocate_string): Omit intervals initialization.

10725 when building with Clang.

10756 * alloc.c: Remove build_string.

10764 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10766 Use sprintf return value instead of invoking strlen on result.
10767 In the old days this wasn't portable, since some sprintf
10768 implementations returned char *. But they died out years ago and
10769 Emacs already assumes sprintf returns int.
10770 Similarly for float_to_string.
10771 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
10772 * ccl.c (ccl_driver):
10773 * character.c (string_escape_byte8):

10776 * print.c (print_object):
10777 * xdisp.c (message_dolog):
10778 * xfns.c (syms_of_xfns):
10779 Use sprintf or float_to_string result to avoid need to call strlen.
10780 * data.c (Fnumber_to_string):
10781 Use make_unibyte_string, since the string must be ASCII.
10782 * lisp.h, print.c (float_to_string): Now returns int length.
10783 * term.c (produce_glyphless_glyph):
10784 Use sprintf result rather than recomputing it.
10786 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10787 * Makefile.in (ALL_CFLAGS):
10788 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

10794 strcasecmp if available.

10813 sprintf already null-terminates its output.
10815 * xfns.c (x_window): Remove redundant cast.
10817 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10819 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10820 `const char *' to `char *' to avoid compiler warning.
10822 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10824 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10825 instead of truncating it to 63 (admittedly a generous limit).
10827 * process.c: Fix spelling and caps in comments.
10829 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10831 * emacs.c (setpgrp): Remove definition, unused.

10841 (SYSTIME_H): Add nt/inc/sys/time.h.
10843 * systime.h [WINDOWSNT]: Include sys/time.h.
10845 * s/ms-w32.h (struct timespec): Definition moved from
10846 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
10848 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

10882 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10883 * lisp.h (WAIT_READING_MAX): New macro.
10884 * dispnew.c (Fsleep_for, sit_for):
10885 * keyboard.c (kbd_buffer_get_event):
10886 * process.c (Faccept_process_output):
10887 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10888 This improves on the previous patch, which introduced a bug
10889 when time_t is unsigned and as wide as intmax_t.
10890 See <http://bugs.gnu.org/9000#51>.
10892 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10921 language ID in the event parameters.
10923 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10924 event.code, not the obscure "character set ID".

10955 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10957 Support higher-resolution time stamps (Bug#9000).
10958 The time stamps are only nanosecond-resolution at the C level,
10959 since that's the best that any real-world system supports now.
10960 But they are picosecond-resolution at the Lisp level, as that's
10961 easy, and leaves room for future OS improvements.
10963 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10966 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10967 Don't get current time unless it's needed.
10969 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10970 now provides it if it's absent.
10971 (start_atimer): Port to higher-res time stamps.
10972 Check for time stamp overflow. Don't get current time more
10973 often than is needed.
10975 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10976 Include systime.h, not time.h.
10977 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10979 * dired.c: Include stat-time.h.
10980 (Ffile-attributes): File times now have higher resolution.
10982 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10983 (struct image): Timestamp now has higher resolution.
10985 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10986 has at least microseconds now. All uses removed.
10987 (update_frame, update_single_window, update_window, update_frame_1)
10988 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10989 (duration_to_sec_usec): Remove; no longer needed.
10991 * editfns.c (time_overflow): Now extern.
10992 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10993 (float-time, Fformat_time_string, Fcurrent_time_string)

10997 (decode_time_components, lisp_seconds_argument): New functions.
10998 (make_time): Now static.
10999 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11000 Report an error if the time is invalid, rather than having the caller
11003 * fileio.c: Include <stat-time.h>
11004 (Fcopy_file): Copy higher-resolution time stamps.
11005 Prefer to set the time stamp via a file descriptor if that works.
11006 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11007 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11008 (Fvisited_file_modtime, Fset_visited_file_modtime):
11009 Support higher-resolution time stamps.
11011 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11013 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11015 * image.c (prepare_image_for_display, clear_image_cache)
11016 (lookup_image): Port to higer-resolution time stamps.
11018 * keyboard.c (start_polling, bind_polling_period):
11019 Check for time stamp overflow.
11020 (read_char, kbd_buffer_get_event, timer_start_idle)
11021 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11022 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11023 Port to higher-resolution time stamps. Do not assume time_t is signed.
11024 (decode_timer): New function. Timers are now vectors of length 9,
11025 not 8, to accommodate the picosecond component.
11026 (timer_check_2): Use it.
11028 * nsterm.m (select_timeout, timeval_subtract): Remove.
11029 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11030 as they're a bit more accurate and handle overflow better.
11031 (ns_select): Change prototype to be compatible with pselect.
11032 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11033 * nsterm.h (ns_select): Adjust prototype.
11035 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11036 us-resolution time stamps.
11037 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11039 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11041 * lisp.h (time_overflow): New decl.
11042 (wait_reading_process_output): First arg is now intmax_t, not int,
11043 to accommodate larger waits.
11045 * process.h (struct Lisp_Process.read_output_delay):
11046 Now counts nanoseconds, not microseconds.
11047 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11049 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11050 (wait_reading_process_output):
11051 Port to ns-resolution time stamps.
11052 (Faccept_process_output, wait_reading_process_output):
11053 Check for time stamp overflow. Do not assume time_t is signed.
11054 (select_wrapper): Remove; we now use pselect.
11055 (Fprocess_attributes): Now generates ns-resolution time stamps.
11057 * sysdep.c: Include utimens.h. Don't include utime.h
11058 or worry about struct utimbuf; gnulib does that for us now.
11059 (gettimeofday): Remove; gnulib provides a substitute.
11060 (make_timeval): New function.
11061 (set_file_times): Now sets ns-resolution time stamps.
11062 New arg FD; all uses changed.
11063 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11064 (system_process_attributes):
11065 Now returns ns-resolution time stamp. All uses changed.
11066 Check for time stamp overflow.
11068 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11069 provides a substitute now.
11071 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11072 since it guarantees struct timespec.
11073 (EMACS_TIME): Now struct timespec, so that we can support
11074 ns-resolution time stamps.
11075 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11076 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11077 (EMACS_USECS): Remove.
11078 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11079 so multiply the arg by 1000 before storing it.
11080 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11082 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11083 Port to ns-resolution time stamps.
11084 (EMACS_TIME_NEG_P): Remove; replaced by....

11087 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
11088 (set_file_times, make_time, lisp_time_argument): Adjust signature.
11089 (make_timeval, make_lisp_time, decode_time_components): New decls.
11090 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11091 that it mishandled time_t overflow. You can't compare by subtracting!
11092 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11093 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11095 * term.c: Include <sys/time.h>.
11096 (timeval_to_Time): New function, for proper overflow wraparound.
11097 (term_mouse_position, term_mouse_click): Use it.
11099 * undo.c (record_first_change): Support higher-resolution time stamps
11100 in the undo buffer.
11101 (Fprimitive_undo): Use them when restoring time stamps.
11103 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11104 (w32_get_internal_run_time):
11105 Port to higher-resolution Emacs time stamps.
11106 (ltime): Now accepts single 64-bit integer, as that's more convenient
11109 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11111 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11112 for compatibility with pselect. Support ns-resolution time stamps.
11114 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11116 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11117 Check for time stamp overflow, and support ns-resolution time stamps.
11119 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11120 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11121 (timeval_subtract): Remove; no longer needed.
11122 (XTflash, XTring_bell, x_wait_for_event):
11123 Port to ns-resolution time stamps. Don't assume time_t is signed.
11125 2012-06-22 Chong Yidong <cyd@gnu.org>

11129 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11131 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11132 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11133 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11134 staticidx goes up to 1597 out of 1600 = 0x640.)
11136 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11138 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
11139 Otherwise, the umask might be mistakenly 0 while handling input signals.
11141 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

11149 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
11150 access to `contents' member of Lisp_Vector objects with AREF and ASET
11153 2012-06-19 Chong Yidong <cyd@gnu.org>
11155 * frame.c (delete_frame): When selecting a frame on a different
11156 text terminal, do not alter the terminal's top-frame.
11158 * xdisp.c (format_mode_line_unwind_data): Record the target
11159 frame's selected window and its terminal's top-frame.
11160 (unwind_format_mode_line): Restore them.
11161 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11163 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11164 since tty frames can be explicitly named.
11165 (prepare_menu_bars): Likewise.
11167 * term.c (Ftty_top_frame): New function.
11169 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

11172 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11173 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11174 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11175 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
11176 (METER_1, METER_2): Simplify.
11178 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

11182 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11184 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11185 gets killed during executing of this function (Bug#11665).
11186 Try to always return Qt when the buffer has been actually killed.
11187 (Vkill_buffer_query_functions): In doc-string say that functions
11188 run by this hook should not change the current buffer.
11190 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11192 Fix recently-introduced process.c problems found by static checking.
11193 * process.c (write_queue_push, write_queue_pop, send_process):
11194 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
11195 (write_queue_pop): Fix pointer signedness problem.
11196 (send_process): Remove unused local.
11198 2012-06-17 Chong Yidong <cyd@gnu.org>

11210 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
11212 * lisp.h (eassert): Assume C89 or later.
11213 This removes the need for CHECK.
11214 (CHECK): Remove. Its comments about always evaluating its
11215 argument were confusing, as 'eassert' typically does not evaluate
11218 * coding.c (produce_chars): Use ptrdiff_t, not int.
11220 * xterm.c (x_draw_underwave): Check for integer overflow.
11221 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

11225 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
11226 referenced (Bug#11583).

11314 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
11315 If all the glyphs of the glyph row came from strings, and we have no
11316 cursor positioning clues, put the cursor on the first glyph of the

11319 indexing into it->string_overlays array. (Bug#11653)
11320 (set_cursor_from_row): Use the leftmost glyph as GLYPH_BEFORE, not
11321 the rightmost. (Bug#11720)

11343 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
11344 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):

11394 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
11395 * alloc.c (make_number) [!defined make_number]:
11396 Remove, as lisp.h always defines this now.
11397 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
11398 (roundup_size): Verify that it is a power of 2.

11403 USE_LSB_TAG now is always defined to be either 0 or 1.
11405 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
11406 code works fine either way, and efficiency is not a concern here,
11407 as the union type is for debugging, not for production.
11408 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
11409 Use an inline function on all platforms when using the union type,
11410 since this is simpler and 'static inline' can be used portably
11412 (LISP_INITIALLY_ZERO): New macro.
11413 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
11414 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

11516 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
11517 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
11519 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11521 * alloc.c (allocate_vectorlike): Fix last change.
11523 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
11525 Block-based vector allocation of small vectors.
11526 * lisp.h (struct vectorlike_header): New field `nbytes',
11527 adjust comment accordingly.
11528 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
11529 to denote vector blocks. Adjust users (live_vector_p,
11530 mark_maybe_pointer, valid_lisp_object_p) accordingly.

11552 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11554 * doprnt.c (doprnt): Truncate multibyte char correctly.
11555 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11556 would mishandle a string argument "Xc" if X was a multibyte
11557 character of length 2: it would truncate after X's first byte
11558 rather than including all of X.
11560 2012-06-06 Chong Yidong <cyd@gnu.org>
11562 * buffer.c (word_wrap): Doc fix.

11609 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11611 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11612 Convert pctcpu and pctmem to Lisp float properly.
11613 Let the compiler fold better, as 100.0/0x8000 is exact.
11615 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11617 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

11624 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11626 For a 'struct window', replace some Lisp_Object fields to
11627 bitfields where appropriate, remove unused fields.
11628 * window.h (struct window): Remove unused 'last_mark_x' and
11629 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11630 change its type from Lisp_Object to bitfield.
11631 Change type of 'force_start', 'optional_new_start',
11632 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

11639 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11640 Use 'float' consistently, rather than 'float' in most places
11641 and 'double' in a couple of places.
11643 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11645 * xdisp.c (handle_stop): Detect whether we have overlay strings
11646 loaded by testing it->current.overlay_string_index to be
11647 non-negative, instead of checking whether n_overlay_strings is
11648 positive. (Bug#11587)
11650 2012-05-31 Chong Yidong <cyd@gnu.org>
11652 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11658 * search.c (search_buffer): Remove calls to
11659 r_alloc_inhibit_buffer_relocation, as it is now called by
11660 maybe_unify_char, which was the cause of relocation of buffer text
11663 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11665 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11666 for the duration of call to load_charset, to avoid problems with
11667 callers of maybe_unify_char that access buffer text through C
11670 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11671 decrement the inhibition flag, instead of just setting or
11674 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11676 Remove obsolete '#define static' cruft.
11677 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11678 This #undef was "temporary" in 2000; it is no longer needed
11679 now that '#define static' has gone away.
11680 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11681 (gray_bitmap_bits): Remove; no longer needed.

11694 (safe_bcopy): Remove decl; no longer has that name.
11695 (main): Coalesce #if into single bit of code, for simplicity.
11696 Cast pointers to uintptr_t, since standard libraries want integers

11725 Do not create empty overlays with the evaporate property (Bug#9642).
11726 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11727 Bug#9642, but explicitly check that the buffer the overlay would
11728 be moved to is live and rearrange lines to make sure that errors
11729 will not put the overlay in an inconsistent state.
11730 (Fdelete_overlay): Cosmetics.
11732 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11734 * w32term.c (my_bring_window_to_top): New function.
11735 (x_raise_frame): Use handle returned by DeferWindowPos, which

11749 This avoids undefined behavior that might cause the eassert
11750 to not catch an out-of-range value.
11752 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11754 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

11764 when referring to sectname field in printf format.
11766 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11768 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11769 Only r_alloc_inhibit_buffer_relocation needed to be added;
11770 the others were already declared.
11772 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11773 before checking whether it's out of range. Put the check inside
11775 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11777 2012-05-27 Ken Brown <kbrown@cornell.edu>
11779 * callproc.c (Fcall_process): Restore a line that was accidentally
11780 commented out in the 2011-02-13 change (bug#11547).
11782 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11784 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11785 defined on ralloc.c.
11787 * buffer.c [REL_ALLOC]: Remove prototypes of
11788 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11789 they are now on lisp.h.
11791 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11793 * search.c (search_buffer): Use it to inhibit relocation of buffer
11794 text while re_search_2 is doing its job, because re_search_2 is
11795 passed C pointers to buffer text. (Bug#11519)
11797 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11798 Update value to 24.
11800 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11801 state after an additional call to move_it_in_display_line_to, keep
11802 the values of it->max_ascent and it->max_descent found for the
11804 (pos_visible_p): Revert the comparison against bottom_y to what it
11805 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11808 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11810 Fix coding-related core dumps with gcc -ftrapv.
11811 The code was computing A - B, where A and B are pointers, and B is
11812 random garbage. This can lead to core dumps on platforms that
11813 have special pointer registers, and it also leads to core dumps on
11814 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11815 A - B only when B is initialized properly.
11816 * coding.c (coding_set_source, coding_set_destination): Return void.
11817 (coding_change_source, coding_change_destinations): New functions,
11818 with the old behaviors of coding_set_source and coding_set_destination.
11819 All callers that need an offset changed to use these new functions.
11821 2012-05-26 Glenn Morris <rgm@gnu.org>
11823 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11825 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11827 Extend mouse support on W32 text-mode console.
11828 * xdisp.c (draw_row_with_mouse_face):
11829 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11831 * w32console.c: Include window.h.
11832 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11834 (initialize_w32_display): Initialize mouse-highlight data.
11836 * w32inevt.c: Include termchar.h and window.h.
11837 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11838 moves, call note_mouse_highlight. If help_echo changed, call
11839 gen_help_event to produce help-echo message in the echo area.
11840 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11843 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11845 * lread.c (read1): Simplify slightly to avoid an overflow warning
11846 with GCC 4.7.0 on x86-64.
11848 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11850 * bidi.c (bidi_mirror_char): Revert last change: an int is
11851 definitely wide enough here.
11853 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11855 Fix integer width and related bugs (Bug#9874).

11867 Use int, not EMACS_INT, where int is wide enough.
11868 (inhibit_garbage_collection, Fgarbage_collect):
11869 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11870 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11871 int might not be wide enough.
11872 (bidi_cache_search, bidi_cache_find, bidi_init_it)

11887 (Foverlay_recenter, last_overlay_modification_hooks_used)
11888 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11889 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11890 (validate_region): Omit unnecessary test for b <= e,
11891 since that's guaranteed by the previous test.
11892 (adjust_overlays_for_delete): Avoid pos + length overflow.
11893 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11894 (report_overlay_modification):
11895 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11896 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11897 Omit pointer cast, which isn't needed anyway, and doesn't work
11898 after the EMACS_INT -> ptrdiff_t change.
11899 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11900 * buffer.h: Adjust decls to match defn changes elsewhere.
11901 (struct buffer_text, struct buffer):
11902 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11903 Use EMACS_INT, not int, where int might not be wide enough.
11904 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11905 not int, to avoid needless 32-bit limit on 64-bit hosts.
11906 (exec_byte_code): Use tighter memory-full test, one that checks
11907 for alloca overflow. Don't compute the address of the object just
11908 before an array, as that's not portable. Use EMACS_INT, not
11909 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11910 * callint.c (Fcall_interactively):
11911 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11912 * callproc.c (call_process_kill, Fcall_process):
11913 Don't assume pid_t fits into an Emacs fixnum.
11914 (call_process_cleanup, Fcall_process, child_setup):

11922 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11923 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11924 (casify_object): Avoid integer overflow when overallocating buffer.
11925 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11926 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11927 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11928 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11929 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11930 integers are now checked earlier. All uses replaced with XINT.
11932 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11933 For CCL_MapSingle, check that content and value are in int range.
11934 (ccl_driver, Fregister_code_conversion_map):
11935 Check that Vcode_version_map_vector is a vector.
11936 (resolve_symbol_ccl_program): Check that vector header is in range.
11937 Always copy the vector, so that we can check its contents reliably
11938 now rather than having to recheck each instruction as it's being
11939 executed. Check that vector words fit in 'int'.
11940 (ccl_get_compiled_code, Fregister_ccl_program)
11941 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11942 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11943 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11944 contents are in range.
11945 (Fccl_execute_on_string): Check that status is in range.
11946 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11947 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11948 Accept and return EMACS_INT, not int, because callers can pass values
11949 out of 'int' range.

11955 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11956 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11957 avoid mishandling large integers.
11958 * character.h: Adjust decls to match defn changes elsewhere.
11959 * charset.c (load_charset_map_from_file, find_charsets_in_text)

11966 Remove now-unnecessary CHECK_NATNUMs.
11967 (Fdefine_charset_internal): Check ranges here, more carefully.
11968 Don't rely on undefined behavior with signed left shift overflow.
11969 Don't assume unsigned int fits into fixnum, or that fixnum fits
11970 into unsigned int. Don't require max_code to be a valid fixnum;
11971 that's not true for gb10830 4-byte on a 32-bit host. Allow
11972 invalid_code to be a cons, for the same reason. Require code_offset
11973 to be a character. Avoid int overflow if max_char is close
11975 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11976 this is intended anyway and avoids some undefined behavior.
11977 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11978 INDEX_TO_CODE_POINT, as that's what it expects.
11979 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11980 * charset.h (DECODE_CHAR): Return int, not unsigned;
11981 this is what was intended anyway, and it avoids undefined behavior.
11982 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11983 integer-overflow issues.
11984 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11985 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11986 where the argument is EMACS_INT, and this behavior is not intended.
11987 * chartab.c (Fmake_char_table, Fset_char_table_range)
11988 (uniprop_get_decoder, uniprop_get_encoder):
11989 Don't assume fixnum fits in int.
11990 * cmds.c (move_point): New function, that does the gist of
11991 Fforward_char and Fbackward_char, but does so while checking
11992 for integer overflow more accurately.
11993 (Fforward_char, Fbackward_char): Use it.
11994 (Fforward_line, Fend_of_line, internal_self_insert)
11995 (internal_self_insert):
11996 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12056 Do not attempt to compute the address of the object just before a

12816 are on a TTY, and thus unable to display on the fringes.
12817 That's because the text with the property will not be displayed anyway,
12818 so we need to signal to the caller that this is a "replacing"
12819 display spec. This fixes display when the spec is invalid or we
12822 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12824 * unexaix.c (make_hdr): Fix typo in prototype.
12825 This bug broke the build on AIX. Problem reported by Gilles Pion.
12827 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12829 * keyboard.c (kbd_buffer_get_event): Read special events also in
12830 batch mode. (Bug#11415)
12832 2012-05-12 Glenn Morris <rgm@gnu.org>
12834 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12836 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12838 * lisp.mk (lisp): Add newcomment.elc.
12840 2012-05-12 Glenn Morris <rgm@gnu.org>
12842 * Makefile.in (MKDIR_P): New, set by configure.
12843 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12845 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12847 Remove unused function hourglass_started.
12848 * dispextern.h (hourglass_started):
12849 * w32fns.c (hourglass_started):
12850 * xdisp.c (hourglass_started): Remove.
12852 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12854 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12855 Update dependencies.
12857 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12859 * xgselect.c (xg_select): Put maxfds+1 into a var.
12860 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12862 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12864 2012-05-10 Dave Abrahams <dave@boostpro.com>
12866 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12867 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12869 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12871 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12872 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12873 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12874 Initialize xd_registered_buses.
12876 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12878 Untag more efficiently if USE_LSB_TAG.
12879 This is based on a proposal by YAMAMOTO Mitsuharu in
12880 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12881 For an admittedly artificial (nth 8000 longlist) benchmark on
12882 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12883 Emacs's overall text size by 1%.
12884 * lisp.h (XUNTAG): New macro.
12885 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12886 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12887 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12888 * eval.c (Fautoload):
12889 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12890 * frame.h (XFRAME): Use XUNTAG.
12892 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12893 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12894 Remove unportable assumptions about print widths of types like
12896 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12897 intptr_t when converting between pointer and integer, to avoid GCC
12898 warnings about wrong width.
12900 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12902 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12903 stack for each reader_thread, instead of defaulting to 8MB
12904 determined by the linker. This avoids failures in creating
12905 subprocesses on Windows 7, see the discussion in this thread:
12906 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12908 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12910 Fix up display of the *Minibuf-0* buffer in the mini window.
12911 * keyboard.c (read_char): Don't clear the echo area if there's no
12913 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12914 contents of *Minibuf-0*) if there's no message displayed in its stead.
12916 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12918 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12921 2012-05-06 Chong Yidong <cyd@gnu.org>
12923 * lisp.mk (lisp): Update.
12925 2012-05-05 Jim Meyering <meyering@redhat.com>
12927 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12929 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12931 * data.c (PUT_ERROR): New macro.
12932 (syms_of_data): Use it. Add new error type `user-error'.
12933 * undo.c (user_error): New function.
12934 (Fprimitive_undo): Use it.
12935 * print.c (print_error_message): Adjust print style for `user-error'.
12936 * keyboard.c (user_error): New function.
12937 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12939 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12941 Do not limit current-time-string to years 1000..9999.
12942 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12943 (Fcurrent_time_string): Support any year that is supported by the
12944 underlying localtime representation. Don't use asctime, as it
12945 has undefined behavior for years outside the range -999..9999.
12947 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12949 Fix race conditions involving setenv, gmtime, localtime, asctime.
12950 Without this fix, interrupts could mess up code that uses these
12951 nonreentrant functions, since setting TZ invalidates existing
12952 tm_zone or tzname values, and since most of these functions return
12953 pointers to static storage.
12954 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12955 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12956 Grow the critical sections to include not just invoking
12957 localtime/gmtime, but also accessing these functions' results
12958 including their tm_zone values if any, and any related TZ setting.
12959 (format_time_string): Last arg is now struct tm *, not struct tm **,
12960 so that the struct tm is saved in the critical section.
12961 All callers changed. Simplify allocation of initial buffer, partly
12962 motivated by the fact that memory allocation needs to be outside
12963 the critical section.
12965 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12967 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12968 with RESET_INTERVAL.
12970 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12971 Remove duplicated buffer name initialization.
12973 2012-05-02 Jim Meyering <jim@meyering.net>
12975 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12977 * xfns.c (x_window): Use xstrdup (Bug#11375).
12979 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12981 * xdisp.c (pos_visible_p): If already at a newline from the
12982 display string before the 'while' loop, don't walk back the glyphs
12983 from it3.glyph_row. Solves assertion violation when the display
12984 string begins with a newline (egg.el). (Bug#11367)
12986 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12988 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12991 2012-05-01 Glenn Morris <rgm@gnu.org>
12993 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12994 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12995 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12996 All were removed before 23.1.
12998 * dispnew.c: Remove HAVE_LIBNCURSES test;
12999 it is always true on relevant platforms.
13001 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13002 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13004 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13006 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13008 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13009 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13012 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13014 Do not avoid creating empty evaporating overlays (Bug#9642).
13015 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13016 That is, do not delete an evaporating overlay if it becomes
13017 empty after its bounds are adjusted to fit within its buffer.
13018 This fix caused other problems, and I'm reverting it until we get
13019 to the bottom of them.
13021 2012-04-27 Chong Yidong <cyd@gnu.org>
13023 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13025 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13027 * xdisp.c (pos_visible_p): If the window start position is beyond
13028 ZV, start the display from buffer beginning. Prevents assertion
13029 violation in init_iterator when the minibuffer window is scrolled
13030 via the scroll bar.
13032 * window.c (window_scroll_pixel_based): Likewise.
13034 2012-04-27 Chong Yidong <cyd@gnu.org>
13036 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13038 2012-04-27 Glenn Morris <rgm@gnu.org>
13040 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13041 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13043 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13045 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13046 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13048 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13050 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13051 display element, check also the underlying string or buffer
13052 character. (Bug#11341)
13054 * w32menu.c: Include w32heap.h.
13055 (add_menu_item): If the call to AppendMenuW (via
13056 unicode_append_menu) fails, disable Unicode menus only if we are
13057 running on Windows 9X/Me.
13059 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13061 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13062 (xgetint): Add missing shift for LSB tags.
13064 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13066 * keyboard.c (read_char): Don't wipe echo area for select window
13067 events: These might get delayed via `mouse-autoselect-window'
13070 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13072 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13073 manipulation of :loaded-from data.
13075 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13077 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13078 now a cons (bug#11311).
13080 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13082 Do not create empty overlays with the evaporate property (Bug#9642).
13083 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13084 if it becomes empty after its bounds are adjusted to fit within
13085 its buffer. Without this fix, in a nonempty buffer (let ((o
13086 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13087 yields an empty overlay that has the evaporate property, which is
13088 not supposed to happen.
13090 Fix minor GTK3 problems found by static checking.
13091 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

13096 (emacs_fixed_class_init): Omit unused local.
13097 (emacs_fixed_child_type): Remove; unused.

13099 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13100 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13101 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
13102 (EMACS_FIXED_GET_CLASS): Remove; unused.
13103 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.

13108 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13110 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13111 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13112 (__malloc_size_t, __malloc_ptrdiff_t):
13113 Remove. All uses removed, replaced by the definiens if needed,
13114 since we can assume C89 or better now.
13115 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

13123 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13124 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13125 Define using prototypes, not old style.
13126 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):

13132 Omit no-longer-needed casts.
13133 (valloc): Use getpagesize, not __getpagesize.
13134 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
13135 (struct hdr): The 'magic' member is now size_t, not unsigned long.

13187 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
13188 Do not assume ptrdiff_t is the same width as 'int'.
13190 * alloc.c: Handle unusual debugging option combinations.
13191 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
13192 since the two debugging options are incompatible.
13193 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
13195 (mem_init, mem_insert, mem_insert_fixup):
13196 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

13205 * sysdep.c [__FreeBSD__]: Minor cleanups.
13206 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13207 Use Emacs indenting style more consistently. Avoid some casts.
13208 Use 'double' consistently rather than mixing 'float' and 'double'.
13210 2012-04-21 Eduard Wiebe <usenet@pusto.de>
13212 * sysdep.c (list_system_processes, system_process_attributes):

13247 row, return zero immediately.
13248 (try_cursor_movement): If inside continuation line, don't back up
13249 farther than the first row after the header line, if any.
13250 Don't consider the header-line row as "partially visible", even if
13251 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

13262 * Makefile.in (C_WARNINGS_SWITCH): Remove.
13263 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
13264 (ALL_CFLAGS): Use new macros rather than old.
13265 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
13266 * regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore
13267 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
13268 -Wunused-result, -Wunused-variable. This should go away once
13269 the Emacs and Gnulib regex code is merged.
13270 (xmalloc, xrealloc): Now static.
13272 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

13289 New extern decls, to avoid calling undeclared functions.
13290 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13291 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13292 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13293 (NEED_MEM_INSERT): New macro.
13294 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13295 Remove one incorrect comment and fix another.
13297 Fix minor ralloc.c problems found by static checking.
13298 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

13303 Improve ralloc.c interface checking.
13304 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
13305 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
13306 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
13307 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)

13309 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
13310 Remove decls. This fixes an "It stinks!".
13312 * alloc.c (which_symbols): Fix alignment issue / type clash.
13314 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13316 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
13317 (struct Lisp_Misc_Any): Likewise.
13318 (struct Lisp_Free): Likewise.
13319 * alloc.c (union aligned_Lisp_Symbol): Define.

13327 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
13329 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
13330 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
13331 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13332 * s/netbsd.h, s/sol2-6.h:
13333 Remove definition of GC_MARK_STACK, since the default now works.
13334 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13335 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
13336 no longer the default.
13337 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13339 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13341 * lread.c (lisp_file_lexically_bound_p):
13342 Fix hang at ";-*-\n" (bug#11238).
13344 2012-04-14 Eli Zaretskii <eliz@gnu.org>
13346 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
13347 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

13356 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
13358 2012-04-13 Reuben Thomas <rrt@sc3d.org>
13360 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
13362 2012-04-11 Daniel Colascione <dancol@dancol.org>
13364 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13365 against is gone. It's better to use vfork now so that when Cygwin
13366 gains a new, working vfork, we use it automatically (bug#10398).
13368 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
13370 * window.c (save_window_save): Obey window-point-insertion-type.

13386 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
13388 * w32.c (w32_delayed_load): Record the full path of the library
13389 being loaded (bug#10424).
13391 2012-04-09 Glenn Morris <rgm@gnu.org>
13393 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13394 not just in the obarray, before snarfing them. (Bug#11036)
13396 * Makefile.in ($(leimdir)/leim-list.el):
13397 Pass EMACS rather than BUILT_EMACS.
13399 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
13401 * process.c (make_process):
13402 * process.h: Add integer `gnutls_handshakes_tried' member to
13405 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.

13408 * gnutls.c (gnutls_log_function2i): Convenience log function.
13409 (emacs_gnutls_read): Use new log functions,
13410 `gnutls_handshakes_tried' process member, and
13411 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13412 attempts per process (connection).
13414 2012-04-09 Chong Yidong <cyd@gnu.org>
13416 * eval.c (Fuser_variable_p, user_variable_p_eh)
13417 (lisp_indirect_variable): Functions deleted.
13418 (Fdefvar): Caller changed.
13420 * callint.c (Finteractive, Fcall_interactively):
13421 * minibuf.c (Fread_variable): Callers changed.
13423 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13425 * xdisp.c (set_cursor_from_row): If the display string appears in
13426 the buffer at position that is closer to point than the position
13427 after the display string, display the cursor on the first glyph of
13428 the display string. Fixes cursor display when a 'display' text
13429 property immediately follows invisible text. (Bug#11094)
13431 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13433 composite.c: use 'double' consistently
13434 * composite.c (get_composition_id): Use 'double' consistently
13435 instead of converting 'float' to 'double' and vice versa; this is
13436 easier to understand and avoids a GCC warning.
13438 2012-04-09 Glenn Morris <rgm@gnu.org>
13440 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13441 preparation for dumping it with emacs. (Bug#4789)
13442 (leimdir): New variable.
13443 ($(leimdir)/leim-list.el): New rule.
13444 (emacs$(EXEEXT)): Depend on leim-list.el.

13462 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
13463 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13464 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13465 objects, as mark_maybe_pointer will catch them otherwise.
13466 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13467 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

13476 Support building on MS-Windows with libxml2.
13478 * makefile.w32-in (OBJ2): Add xml.$(O).
13479 (GLOBAL_SOURCES): Add xml.c.
13480 ($(BLD)/xml.$(O)): New dependency list.
13482 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
13483 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13484 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13485 [!WINDOWSNT]: New macros.
13486 (init_libxml2_functions, libxml2_loaded_p): New functions.
13487 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13488 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13489 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13490 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13492 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13493 Call init_libxml2_functions before calling libxml2 functions.
13494 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13496 * emacs.c: Don't include libxml/parser.h.
13497 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13498 xmlCleanupParser directly.
13500 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13502 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13504 * indent.c (Fvertical_motion): If there is a display string at
13505 point, use it.vpos to compute how many lines to backtrack after
13506 move_it_to point. (Bug#11133)
13508 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13510 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13511 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13512 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13513 macros related to unification of CJK characters. For the details,
13514 see the discussion following the message here:
13515 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13517 2012-04-04 Chong Yidong <cyd@gnu.org>
13519 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13521 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13523 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

13531 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13533 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13534 position we get to after a call to move_it_to fails the
13535 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13536 only if we wind up in a string from display property. (Bug#11063)
13538 * window.c (Fdelete_other_windows_internal): Invalidate the row
13539 and column information about mouse highlight, so that redisplay
13540 restores it after reallocating the glyph matrices. (Bug#7464)
13542 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13543 string comes from a `display' text property, use the buffer
13544 position of that property as if we actually saw that position in
13546 (move_it_by_lines): Remove the assertion that
13547 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13548 violated when there's a before-string at the beginning of a line.
13551 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13553 * xdisp.c (append_space_for_newline): If the default face was
13554 remapped, use the remapped face for the appended newline.
13555 (extend_face_to_end_of_line): Use the remapped default face for
13556 extending the face to the end of the line.
13557 (display_line): Call extend_face_to_end_of_line when the default
13558 face was remapped. (Bug#11068)
13560 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13562 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13564 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

13580 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13581 (command_loop_1): Use it; inhibit selection update for
13582 handle-select-window too (Bug#8996).

13586 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13588 2012-03-25 Kenichi Handa <handa@m17n.org>
13590 * dispextern.h (struct glyph): Change the bit length of
13591 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13593 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13595 * s/ms-w32.h (tzname): Include time.h before redirecting to

13600 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13603 * xterm.c (XTread_socket): Only modify handling_signal if
13604 !SYNC_INPUT. (Bug#11080)
13606 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13608 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13609 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13610 when fetching a multibyte character consumes more bytes than
13611 CHAR_BYTES returns, due to unification of CJK characters in
13612 string_char. (Bug#11073)
13614 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13616 * process.c (wait_reading_process_output): Handle pty disconnect
13617 by refraining from sending oneself a SIGCHLD (bug#10933).
13619 2012-03-22 Chong Yidong <cyd@gnu.org>
13621 * dispextern.h (struct it): New member string_from_prefix_prop_p.
13623 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
13624 Mark string as coming from a prefix property.
13625 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13626 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13628 2012-03-21 Chong Yidong <cyd@gnu.org>
13630 * xfaces.c (Vface_remapping_alist): Doc fix.
13632 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13634 * w32proc.c (Fw32_set_console_codepage)
13635 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

13646 it fit in a valid range (Bug#11003).
13648 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13650 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13651 that is not from display property, accept the row as a "cursor
13652 row" if one of the string's character has a non-nil `cursor'
13653 property. Fixes cursor positioning when there are newlines in
13654 overlay strings, e.g. in icomplete.el. (Bug#11035)
13656 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13658 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13660 2012-03-12 Chong Yidong <cyd@gnu.org>
13662 * eval.c (inhibit_lisp_code): Rename from
13663 inhibit_window_configuration_change_hook; move from window.c.
13665 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13666 * window.c (run_window_configuration_change_hook)
13667 (syms_of_window): Callers changed.
13669 2012-03-11 Chong Yidong <cyd@gnu.org>
13671 * keymap.c (Fkey_description): Doc fix (Bug#9700).
13673 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
13675 2012-03-10 Chong Yidong <cyd@gnu.org>
13677 * frame.c (other_visible_frames): Don't assume the selected frame
13678 is visible (Bug#10955).
13680 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13682 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13684 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13686 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13687 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13690 2012-03-03 Glenn Morris <rgm@gnu.org>
13692 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13694 2012-03-02 Eli Zaretskii <eliz@gnu.org>

13697 position past the first glyph_row that ends at ZV. (Bug#10902)
13698 (redisplay_window, next_element_from_string): Fix typos in
13700 (redisplay_window): Pass to move_it_vertically the margin in
13701 pixels, not in screen lines.
13703 2012-03-02 Glenn Morris <rgm@gnu.org>
13705 * buffer.c (buffer-list-update-hook): Doc fix.
13707 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13709 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13710 push_it before setting up the iterator for the first overlay
13711 string, even if we have an empty string loaded.
13712 (next_overlay_string): If there's an empty string on the iterator
13713 stack, pop the stack. (Bug#10903)
13715 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13717 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13718 Suggested by Stefan Monnier in
13719 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13720 * alloc.c (widen_to_Lisp_Object): New static function.
13721 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13722 and widening them to Lisp_Objects. This would work even if
13723 USE_LSB_TAG is defined and wide integers are used, which might
13724 happen in a future version of Emacs.
13726 2012-02-25 Chong Yidong <cyd@gnu.org>
13728 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13731 * xselect.c (Fx_selection_exists_p): Doc fix.
13732 (x_clipboard_manager_save_all): Print an informative message
13733 before saving to clipboard manager.
13735 2012-02-24 Chong Yidong <cyd@gnu.org>
13737 * keyboard.c (process_special_events): Handle all X selection
13738 requests in kbd_buffer, not just the next one (Bug#8869).
13740 2012-02-23 Chong Yidong <cyd@gnu.org>
13742 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13743 call when setting menu-bar-lines and tool-bar-lines parameters.
13744 (unwind_create_frame_1): New helper function.
13746 * window.c (inhibit_window_configuration_change_hook): New var.
13747 (run_window_configuration_change_hook): Obey it.
13748 (syms_of_window): Initialize it.
13750 2012-02-22 Chong Yidong <cyd@gnu.org>
13752 * xterm.c (x_draw_image_relief): Add missing type check for

13764 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13765 when computing $valmask.
13767 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13768 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13769 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13770 It's useless in that case, and it can cause problems on hosts
13771 that allocate halves of EMACS_INT values separately.
13772 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13773 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13774 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13775 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13776 it avoids undefined behavior on hosts where shifting right by more
13777 than the word width has undefined behavior.
13779 2012-02-19 Chong Yidong <cyd@gnu.org>
13781 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13782 (Funhandled_file_name_directory, Ffile_name_as_directory)
13783 (Fdirectory_file_name, Fexpand_file_name)
13784 (Fsubstitute_in_file_name): Protect against invalid file handler
13785 return values (Bug#10845).
13787 2012-02-18 Eli Zaretskii <eliz@gnu.org>

13819 2012-02-12 Chong Yidong <cyd@gnu.org>
13821 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13822 as that creates a dangerous corner case.
13824 * window.c (Fdelete_window_internal): Invalidate the mouse
13825 highlight (Bug#9904).
13827 2012-02-12 Glenn Morris <rgm@gnu.org>

13857 2012-02-07 Chong Yidong <cyd@gnu.org>
13859 * buffer.c (Fbuffer_local_variables)
13860 (buffer_lisp_local_variables): Handle unbound vars correctly;
13861 don't let Qunbound leak into Lisp.
13863 2012-02-07 Glenn Morris <rgm@gnu.org>
13865 * image.c (Fimagemagick_types): Doc fix.
13867 * image.c (imagemagick-render-type): Change it from a lisp object
13868 to an integer. Move the doc here from the lisp manual.

13885 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13887 * w32.c (get_emacs_configuration_options):
13888 Include --enable-checking, if specified, in the return value.

13900 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13902 Handle overflow when computing char display width (Bug#9496).
13903 * character.c (char_width): Return EMACS_INT, not int.
13904 (char_width, c_string_width): Check for overflow when
13905 computing the width; this is possible now that individual
13906 characters can have unbounded width. Problem introduced

13931 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to

13938 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13939 first 2 arguments are identical. This makes inserting large
13940 output from a subprocess an order of magnitude faster on
13941 MS-Windows, where all sbrk'ed memory is always contiguous.

14394 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
14395 verifies glyph row's hash code--we have just reallocated the
14396 glyphs, so their contents can be complete garbage. (Bug#10164)

14560 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14561 is set, removing the need for VIRT_ADDRESS_VARIES.
14562 (PURE_P): Use a more-efficient implementation that needs just one

14569 consistency with the new puresize.h.
14570 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

14577 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14578 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14579 behave as if the cursor position were at the window margin.
14581 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14582 and the cursor position is out of bounds, behave as if the cursor
14583 position were at the window margin. (Bug#10075)
14585 2011-11-18 Chong Yidong <cyd@gnu.org>
14587 * window.c (Fwindow_combination_limit): Make first argument

14608 * xdisp.c (row_hash): New function, body extracted from
14609 compute_line_metrics.
14610 (compute_line_metrics): Call row_hash, instead of computing the
14613 * dispnew.c (verify_row_hash): Call row_hash for computing the
14614 hash code of a row, instead of duplicating code from xdisp.c.
14616 * dispextern.h (row_hash): Add prototype.
14618 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14620 * frame.c (delete_frame): Don't delete the terminal when the last

14645 (recombine_windows, make_parent_window, make_window)
14646 (Fsplit_window_internal, saved_window)
14647 (Fset_window_configuration, save_window_save): Rename all
14648 occurrences of window_nest to window_combination_limit.

14656 * xdisp.c (display_line): Move the call to
14657 highlight_trailing_whitespace before the call to

15116 current character, check also for next_en_type being WEAK_EN.
15117 (bidi_resolve_weak): Don't enter the expensive loop if the current
15118 position is before next_en_pos. Record the bidi type of the first
15119 non-ET, non-BN character we find, in addition to its position.
15120 (bidi_level_of_next_char): Invalidate next_en_type when
15121 next_en_pos is over-stepped.
15123 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15125 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15126 * editfns.c: Rewrite current-time-zone so that it invokes
15127 the equivalent of (format-time-string "%Z") to get the time zone name.
15128 This fixes a bug when the time zone name contains characters that
15129 need converting from the system time locale to Emacs internal format.
15130 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15131 that patch fixed format-time-string to do the conversion, but
15132 I forgot to fix current-time-zone.
15133 (format_time_string): New function, containing most of
15134 what Fformat_time_string used to contain.
15135 (Fformat_time_string): Rewrite in terms of format_time_string.
15136 This doesn't change this function's behavior.
15137 (current-time-zone): Rewrite to use format_time_string.
15138 This fixes the bug reported by Michael Schierl in
15139 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15140 Jason Rumney's 2007-06-07 change worked around this bug, but
15142 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15144 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15146 * xdisp.c (start_display): If the character at POS is displayed
15147 via a display vector, reset IT->current.dpvec_index to zero.
15148 (try_window_reusing_current_matrix): If a line ends in a display
15149 vector or the next line starts in a display vector, continue
15150 redrawing the window even though the character position of
15151 start_row was reached.
15154 2011-10-18 Chong Yidong <cyd@gnu.org>
15156 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15157 with nobreak-char-display too.
15159 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15161 Fix part 3 of bug#9771.
15162 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15163 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15164 non-neutral characters if the current character is a paragraph
15165 separator (a.k.a. Newline). This avoids running the same
15166 expensive loop twice, once when we consume the preceding newline
15167 and the other time when the line actually needs to be displayed.
15168 Avoid the loop when we see neutrals on the base embedding level
15169 following a character whose directionality is the same as the
15170 paragraph's. This avoids running the expensive loop when a line
15171 ends in a long sequence of neutrals, like control characters.
15172 Add assertion against STRONG_AL type. Slightly rearrange code
15173 that determines the type of a neutral given the first non-neutral
15175 (bidi_level_of_next_char): Set next_en_pos to zero when
15176 invalidating its info.
15178 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15180 * xdisp.c (push_display_prop): Determine whether to record string
15181 or buffer position by IT->string, not by IT->method. Allow
15182 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15183 (move_it_vertically_backward): Don't look for character position
15184 immediately after the newline when in a continuation line.
15187 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15189 * window.c (coordinates_in_window): Rewrite and delabelize
15190 vertical border check. (Bug#5357) (Bug#9618)
15192 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15194 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15195 errors in XSetWindowBorder (bug#9310).
15197 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15199 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15200 avoid crash when xmalloc overrun checking is enabled.
15202 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15204 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15205 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15206 cursor motion with <left> and <right> arrow keys.
15208 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15209 some callers set that themselves.
15211 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15213 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15214 display string and the previous row comes from the same string and
15215 is empty. (Bug#9739) (Bug#9738)
15217 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15219 * doc.c (get_doc_string): Encode file name (bug#9735).
15221 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15223 * bidi.c (bidi_level_of_next_char):
15224 * xdisp.c (get_visually_first_element): Remove old incorrect
15225 comments regarding the Unicode Line Separator character.
15227 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15229 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15231 * alloc.c (Fgc_status): Do not access beyond zombies array
15232 boundary if nzombies > MAX_ZOMBIES.
15233 * alloc.c (dump_zombies): Add missing format specifier.
15235 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15237 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15238 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15240 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15241 Some packages use them to denote characters with modifiers.
15243 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15245 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15246 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15247 matching a pp-number. Rename parameter var to var1.
15249 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15251 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15253 2011-10-08 Glenn Morris <rgm@gnu.org>
15255 * callint.c (Fcall_interactively): Give a more explicit error for the
15256 'c' case with a non-character input. (Bug#8479)
15258 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15260 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15262 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15263 lines that are hscrolled on the left.
15265 * dispnew.c (buffer_posn_from_coords): Account for a possible
15266 presence of header-line. (Bug#4426)
15268 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15270 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15271 Don't advertise functionality which we discourage or doesn't work.
15273 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15275 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15276 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15277 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15278 this makes Emacs dump core during garbage collection on rare
15279 occasions. sizeof is obviously inferior to offsetof here, so
15280 stick with offsetof.
15281 (GC_POINTER_ALIGNMENT): New macro.
15282 (mark_memory): Omit 3rd (offset) arg; caller changed.
15283 Don't assume EMACS_INT alignment is the same as pointer alignment.
15285 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15287 * keyboard.c (read_key_sequence_remapped): New var.
15288 (read_key_sequence): Compute remapping in the right buffer.
15289 (command_loop_1): Use read_key_sequence's remapping directly.
15291 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15293 * dired.c (file_name_completion): Don't expand file name.
15294 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15295 before checking file name handler.
15297 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15298 they've been requested explicitly (bug#9591).
15300 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15302 * keymap.c (Fsingle_key_description): Use make_specified_string
15303 instead of build_string to build string from push_key_description.
15306 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15308 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15309 This fixes a Y2038 bug on 64-bit hosts.
15310 * buffer.c (reset_buffer):
15311 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15312 (Fclear_buffer_auto_save_failure):
15313 Use 0, not -1, to represent an unset failure time, since time_t
15314 might not be signed.
15316 Remove dependency on glibc malloc internals.
15317 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15318 Move back here from lisp.h, but with their new implementations.
15319 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15320 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15321 * charset.c (charset_table_init): New static var.
15322 (syms_of_charset): Use it instead of xmalloc. This removes a
15323 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15324 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15325 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15326 Move back to alloc.c.
15327 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15328 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15330 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15332 * nsterm.m (windowDidResize): Call x_set_window_size only when
15333 ns_in_resize is true. Otherwise set pixelwidth/height and
15334 call change_frame_size (Bug#9628).
15336 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15338 Port --enable-checking=all to Fedora 14 x86-64.
15339 * charset.c (syms_of_charset): Also account for glibc malloc's
15340 internal overhead when calculating the initial malloc maximum.
15342 Port --enable-checking=all to Fedora 14 x86.
15343 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15345 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15346 (overrun_check_realloc, overrun_check_free):
15347 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15348 That way, xmalloc returns a properly-aligned pointer even if
15349 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15350 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15351 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15352 into account when calculating the initial malloc maximum.
15353 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15354 Move here from alloc.c, so that charset.c can use it too.
15355 Properly align; the old code wasn't right for common 32-bit hosts
15356 when configured with --enable-checking=all.
15357 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15358 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15360 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15362 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15365 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15367 * xdisp.c (compute_display_string_end): If there's no display
15368 string at CHARPOS, return -1.
15370 * bidi.c (bidi_fetch_char): When compute_display_string_end
15371 returns a negative value, treat the character as a normal
15372 character not covered by a display string. (Bug#9624)
15374 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15376 * lread.c (Fread_from_string): Fix typo in docstring.
15378 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15380 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15381 newline, reseat the iterator instead of bidi-iterating there one
15382 character at a time. (Bug#9610)
15383 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15384 TO_CHARPOS if the bidi iterator is at base embedding level.
15386 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15388 * lread.c (readevalloop): Use correct code for NBSP.
15389 (read1): Likewise. (Bug#9608)
15391 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15393 * dbusbind.c (Fdbus_register_signal): When service is not
15394 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15396 2011-09-25 Glenn Morris <rgm@gnu.org>
15398 * buffer.c (truncate-lines): Doc fix.
15400 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15402 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15403 (Fset_window_next_buffers): Doc fix.
15405 2011-09-24 Glenn Morris <rgm@gnu.org>
15407 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15409 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15411 Fix minor problems found by static checking.
15412 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15413 * indent.c (Fvertical_motion): Fix == vs = typo.
15415 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15417 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15418 Default value is now t. Doc fix.
15420 * indent.c (Fvertical_motion): Compute and apply the overshoot
15421 logic when moving up, not only when moving down. Fix the
15422 confusing name and values of the it_overshoot_expected variable;
15423 logic changes accordingly. (Bug#9254) (Bug#9549)
15425 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15426 CHARPOS is covered by a display string which includes newlines.
15427 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15428 is covered by a display string with embedded newlines.
15430 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15432 * dbusbind.c (Fdbus_register_signal): Add match rule to
15433 Vdbus_registered_objects_table. (Bug#9581)
15434 (Fdbus_register_method, Vdbus_registered_objects_table):
15437 2011-09-24 Jim Meyering <meyering@redhat.com>
15439 do not ignore write error for any output size
15440 The previous change was incomplete.
15441 While it makes emacs --batch detect the vast majority of stdout
15442 write failures, errors were still ignored whenever the output size is
15443 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15444 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15445 && echo FAIL: ignored write error
15446 FAIL: ignored write error
15447 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15448 && echo FAIL: ignored write error
15449 FAIL: ignored write error
15450 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15452 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15454 * emacs.c (Fkill_emacs): In noninteractive mode exit
15455 non-successfully if a write error occurred on stdout. (Bug#9574)
15457 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15459 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15462 * dispextern.h (struct it): Update the comment documenting what
15465 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15467 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15468 a display string, extend search for cursor position to end of row.
15469 (find_row_edges): If the row ends in a newline from a display
15470 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15471 Handle the case of a display string with multiple newlines.
15472 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15473 non-empty line. Fixes confusing cursor motion with arrow keys at
15474 the beginning of a line that starts with whitespace.
15476 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15478 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15481 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15483 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15484 boolean (Bug#9154).
15486 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15488 * xdisp.c (display_line): Record maximum and minimum buffer
15489 positions even if no glyphs were produced (e.g., by a zero-width
15490 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15491 buffer positions that will be removed from the glyph row because
15493 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15494 column is beyond frame width: don't subtract 1 "pixel" when
15495 computing width of the stretch.
15496 (reseat_at_next_visible_line_start): Undo the change made on
15497 2011-09-17 that saved paragraph information and restored it after
15498 the call to `reseat'. (Bug#9545)
15500 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15502 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15503 and turn window cursor on if cleared (Bug#9415).
15505 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15507 * search.c (boyer_moore): Take unibyte characters from pattern
15508 literally. (Bug#9458)
15510 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15512 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15514 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15516 Fix minor problem found by static checking.
15517 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15518 initialized, to pacify gcc -Wuninitialized.
15520 * fileio.c: Report proper errno when syscall falls.
15521 (Finsert_file_contents): Save and restore errno,
15522 so that report_file_error outputs the correct diagnostic.
15523 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15525 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15527 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15529 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15531 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15532 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15534 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15536 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15537 about the current paragraph and restore it after the call to reseat.
15539 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15540 (bidi_find_paragraph_start): Search back for paragraph beginning
15541 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15542 (bidi_move_to_visually_next): Only trigger paragraph-related
15543 computations when the last character is a newline or at EOB, not
15544 just any NEUTRAL_B. (Bug#9470)
15546 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15547 truncated lines if point is covered by a display string. (Bug#9524)
15549 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15551 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15552 (cons_to_x_long): New function.
15553 (lisp_data_to_selection_data): Use it. Correct the test for
15554 short-versus-long data; it was negated. Break out of vector
15555 loop, for efficiency, when a long datum is discovered.
15557 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15559 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15561 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15563 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15564 GCC PR/17406) by declaring this function with external scope.
15566 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15568 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15569 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15571 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15573 * editfns.c (Fformat): Correctly handle text properties on "%%".
15575 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15577 * xterm.c (x_draw_composite_glyph_string_foreground):
15578 * w32term.c (x_draw_composite_glyph_string_foreground):
15579 * term.c (encode_terminal_code):
15580 * composite.c (composition_update_it, get_composition_id):
15581 * xdisp.c (get_next_display_element)
15582 (fill_composite_glyph_string): Add comments about special meaning
15583 of TAB characters in a composition.
15585 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15587 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15588 This occurs when processing a multibyte format.
15589 Problem reported by Wolfgang Jenker.
15591 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15593 * xdisp.c (try_cursor_movement): Only check for exact match if
15594 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15596 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15598 Remove unused external symbols.
15599 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15600 * xdisp.c (calc_pixel_width_or_height): Now static.
15601 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15602 * indent.c (check_display_width):
15603 * w32term.c: Fix comment to match code.
15604 * xterm.c, xterm.h (x_catching_errors): Remove.
15606 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15608 * xselect.c: Use signed conversions more consistently (Bug#9498).
15609 (selection_data_to_lisp_data): Assume incoming selection data are
15610 signed integers, not unsigned. This is to be consistent with
15611 outgoing selection data, which was modified to use signed integers
15612 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15613 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15614 expects long, not unsigned long.
15616 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15618 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15619 computation of loop end. Reported by Johan Bockgård
15622 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15624 * frame.c (Fother_visible_frames_p): Function deleted.
15626 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15628 * indent.c (compute_motion): Process display vector front to back
15629 rather than the other way around. (Bug#2496)
15631 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15633 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15635 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15637 * minibuf.c (Fread_from_minibuffer): Doc fix.
15639 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15641 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15642 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15644 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15646 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15647 value for non-existent files.
15649 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15651 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15652 set its "size" to -1. This will set the modtime_size field of
15653 the corresponding buffer to -1, which is what
15654 verify-visited-file-modtime expects for files that do not exist.
15657 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15659 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15661 * lisp.h: ... from here. push_key_description is no longer
15662 defined in keyboard.c, so its declaration should not be in
15663 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15664 logically belongs with push_key_description.
15666 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15668 * buffer.h: Include <sys/types.h> instead of <time.h>.
15669 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15670 Problem reported by Herbert J. Skuhra.
15672 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15674 * xml.c (parse_region): Make the parsing work for
15675 non-comment-starting XML files again (bug#9144).
15677 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15679 * image.c (gif_load): Fix calculation of bottom and right corner.
15682 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15684 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15685 redisplay in small windows.
15687 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15689 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15691 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15693 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15694 Operate on live windows only.
15696 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15698 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15700 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15702 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15703 only under bidi iteration.
15705 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15707 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15709 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15711 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15712 Without this fix, the command to link temacs failed due to an
15713 undefined symbol __builtin_isnan. This is because
15714 /usr/include/iso/math_c99.h #defines isnan(x) to
15715 __builtin_isnan(x), but the bundled gcc, which identifies itself
15716 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15718 * floatfns.c (isnan): #undef, and then #define to a clone of
15720 (Fisnan): Always define, since it's always available now.
15721 (syms_of_floatfns): Always define isnan at the Lisp level.
15723 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15725 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15727 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15729 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15730 The previous code assumed that file offsets (off_t values) fit in
15731 EMACS_INT variables, which is not true on typical 32-bit hosts.
15732 The code messed up by falsely reporting buffer overflow in cases
15733 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15734 when "big" contains more than 2**29 bytes, even though this
15735 inserts just one byte and does not overflow the buffer.
15736 (Finsert_file_contents): Store file offsets as off_t
15737 values, not as EMACS_INT values. Check for overflow when
15738 converting between EMACS_INT and off_t. When checking for
15739 buffer overflow or for overlap, take the offsets into account.
15740 Don't use EMACS_INT for small values where int suffices.
15741 When checking for overlap, fix a typo: ZV was used where
15742 ZV_BYTE was intended.
15743 (Fwrite_region): Don't assume off_t fits into 'long'.
15744 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15746 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15748 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15750 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15752 sprintf-related integer and memory overflow issues (Bug#9412).
15754 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15755 (esprintf, exprintf, evxprintf): New functions.
15756 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15757 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15758 (modify_event_symbol): Do not assume that the length of
15759 name_alist_or_stem is safe to alloca and fits in int.
15760 (Fexecute_extended_command): Likewise for function name and binding.
15761 (Frecursion_depth): Wrap around reliably on integer overflow.
15762 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15763 since some callers pass EMACS_INT values.
15764 (Fsingle_key_description): Don't crash if symbol name contains more
15765 than MAX_ALLOCA bytes.
15766 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15767 (get_minibuffer): Arg is now EMACS_INT, not int.
15768 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15769 (esprintf, exprintf, evxprintf): New decls.
15770 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15772 * dbusbind.c (signature_cat): New function.
15773 (xd_signature, Fdbus_register_signal):
15774 Do not overrun buffer; instead, report string overflow.
15776 * dispnew.c (add_window_display_history): Don't overrun buffer.
15777 Truncate instead; this is OK since it's just a log.
15779 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15780 even if the time zone offset is outlandishly large.
15781 Don't mishandle offset == INT_MIN.
15783 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15784 when creating daemon; the previous buffer-overflow check was incorrect.
15786 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15787 which has the guts of the old verror function.
15789 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15790 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15792 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15793 (font_unparse_xlfd): Don't blindly alloca long strings.
15794 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15795 fits in int, when using sprintf. Use single snprintf to count
15796 length of string rather than counting it via multiple sprintfs;
15797 that's simpler and more reliable.
15798 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15799 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15800 sprintf, in case result does not fit in int.
15802 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15803 (fontset_from_font): Print it.
15805 * frame.c (tty_frame_count): Now printmax_t, not int.
15806 (make_terminal_frame, set_term_frame_name): Print it.
15807 (x_report_frame_params): In X, window IDs are unsigned long,
15808 not signed long, so print them as unsigned.
15809 (validate_x_resource_name): Check for implausibly long names,
15810 and don't assume name length fits in 'int'.
15811 (x_get_resource_string): Don't blindly alloca invocation name;
15812 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15815 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15816 (xg_check_special_colors, xg_set_geometry):
15817 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15819 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15820 Use esprintf, not sprintf, in case result does not fit in int.
15822 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15823 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15824 it as a large positive number.
15825 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15826 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15828 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15829 in case result does not fit in int.
15831 * print.c (float_to_string): Detect width overflow more reliably.
15832 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15833 buffer overrun. Don't assume list length fits in 'int'. Treat
15834 print length of 0 as 0, not as infinity; to be consistent with other
15835 uses of print length in this function. Don't overflow print length
15836 index. Don't assume hash table size fits in 'long', or that
15837 vectorlike size fits in 'unsigned long'.
15839 * process.c (make_process): Use printmax_t, not int, to format
15840 process-name gensyms.
15842 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15844 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15845 to avoid potential buffer overrun.
15847 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15848 if X resource line is longer than 512 bytes.
15850 * xfns.c (x_window): Make sprintf buffer a bit bigger
15851 to avoid potential buffer overrun.
15853 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15855 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15857 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15859 Integer overflow fixes for scrolling, etc.
15860 Without these, Emacs silently mishandles large integers sometimes.
15861 For example, "C-u 4294967297 M-x recenter" was treated as if
15862 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15864 * xdisp.c (try_window_id): Check Emacs fixnum range before
15865 converting to 'int'.
15867 * window.c (window_scroll_line_based, Frecenter):
15868 Check that an Emacs fixnum is in range before assigning it to 'int'.
15869 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15870 values converted from Emacs fixnums.
15871 (Frecenter): Don't wrap around a line count if it is out of 'int'
15872 range; instead, treat it as an extreme value.
15873 (Fset_window_configuration, compare_window_configurations):
15874 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15876 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15877 that can exceed INT_MAX. Check that EMACS_INT value is in range
15878 before assigning it to the (possibly-narrower) index.
15879 (match_limit): Don't assume that a fixnum can fit in 'int'.
15881 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15884 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15885 (Fvertical_motion): Don't wrap around LINES values that don't fit
15886 in 'int'. Instead, treat them as extreme values. This is good
15887 enough for windows, which can't have more than INT_MAX lines anyway.
15889 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15891 * Require libxml/parser.h to avoid compilation warning.
15893 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15895 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15896 since this reportedly can destroy thread storage.
15898 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15900 * syntax.c (find_defun_start): Update all cache variables if
15901 exiting early (Bug#9401).
15903 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15905 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15907 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15908 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15909 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15911 * term.c (tty_append_glyph): New function.
15912 (produce_stretch_glyph): Static function and its prototype deleted.
15914 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15917 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15919 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15920 when checking :margin (Bug#9390).
15921 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15922 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15923 so that the name doesn't mislead. All uses changed.
15925 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15927 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15930 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15932 * xdisp.c (move_it_to): Don't bail out early when reaching
15933 position beyond to_charpos, if we are scanning backwards.
15934 (move_it_vertically_backward): When DY == 0, make sure we get to
15935 the first character in the line after the newline.
15937 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15939 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15940 (ccl_driver): Do not generate an out-of-range pointer.
15941 (Fccl_execute_on_string): Remove unnecessary check for
15942 integer overflow, noted by Stefan Monnier in
15943 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15944 Remove a FIXME that didn't need fixing.
15945 Simplify the newly-introduced buffer reallocation code.
15947 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15949 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15951 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15953 Integer and memory overflow issues (Bug#9196).
15955 * doc.c (get_doc_string): Rework so that
15956 get_doc_string_buffer_size is the actual buffer size, rather than
15957 being 1 less than the actual buffer size; this makes xpalloc more
15960 * image.c (x_allocate_bitmap_record, cache_image):
15961 * xselect.c (Fx_register_dnd_atom):
15962 Simplify previous changes by using xpalloc.
15964 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15965 since either will do and ptrdiff_t is convenient with xpalloc.
15967 * charset.c (charset_table_size)
15968 (struct charset_sort_data.priority): Now ptrdiff_t.
15969 (charset_compare): Don't overflow if priorities differ greatly.
15970 (Fsort_charsets): Don't assume list length fits in int.
15971 Check for size-calculation overflow when allocating sort data.
15972 (syms_of_charset): Allocate an initial charset table that is
15973 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15975 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15977 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15978 The actual value is always <= INT_MAX, and leaving it unsigned made
15979 overflow checking harder.
15981 * dispextern.h (struct glyph_matrix.rows_allocated)
15982 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15983 with xpalloc. The values are still always <= INT_MAX.
15985 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15987 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15988 (SAFE_NALLOCA): New macro.
15990 * region-cache.c (struct boundary.pos, find_cache_boundary)
15991 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15992 (set_cache_region, invalidate_region_cache)
15993 (revalidate_region_cache, know_region_cache, region_cache_forward)
15994 (region_cache_backward, pp_cache):
15995 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15996 so that ptrdiff_t * can be passed to xpalloc.
15997 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15998 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15999 (pp_cache): Don't assume cache_len fits in int.
16000 * region-cache.h: Adjust extern decls to match.
16002 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16003 EMACS_INT, since either will do, for xpalloc.
16005 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16006 (xnmalloc, xnrealloc, xpalloc): New functions.
16008 * bidi.c (bidi_shelve_header_size): New constant.
16009 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16010 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16012 * bidi.c (bidi_cache_shrink):
16013 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16015 Don't update size of array until after memory allocation succeeds,
16016 because xmalloc/xrealloc may not return.
16017 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16018 now that we have proper integer overflow checking.
16019 (record_overlay_string, overlay_strings): Catch overflows when

16022 * callproc.c (Fcall_process): Check for size overflow when
16023 calculating size of args2.
16024 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.

16026 require adding more-complicated checks.
16028 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16029 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

16069 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16071 * emacs.c (main): Do not reallocate argv, since there is a null at
16072 the end that can be overwritten, and this way there's no need to
16073 worry about size-calculation overflow.
16074 (sort_args): Check for size-calculation overflow.
16076 * eval.c (init_eval_once, grow_specpdl): Don't update size until

16082 Check for integer overflow.
16083 (x_set_alpha): Do not assume XINT fits in int.
16085 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16086 This is for the members text_lines, text_cols, total_lines, total_cols,
16087 where the system imposes an 'int' limit.

16096 Check for size-calculation overflow.
16097 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16098 do, as we prefer signed integers.

16202 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16203 (X_LONG_MIN): New macros.
16204 Use them to make the following changes clearer.
16205 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16206 This change doesn't affect the value now, but it may help remind
16207 future maintainers not to raise the value too much later.
16208 (SELECTION_QUANTUM): Remove, replacing with ...
16209 (selection_quantum): ... new function, which avoids overflow.
16211 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16212 assumption that selection length fits in 'int'.

16229 Don't store size until memory allocation succeeds.
16230 (x_get_window_property): Plug memory leak on memory exhaustion.
16231 Don't double-block input; malloc is safe here. Don't assume 2**34
16232 - 4 fits in unsigned long. Add an xassert to check
16233 XGetWindowProperty overflow. Be more careful about overflow
16234 calculations, and distinguish size from memory overflow better.
16235 (receive_incremental_selection): When tracing, don't assume
16236 unsigned int is less than INT_MAX.
16237 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

16240 in the range -65535 through -1 fit in an X unsigned short.
16241 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16242 result parameters unless successful. Rely on cons_to_unsigned
16243 to report problems with elements; the old code wasn't right anyway.
16244 (x_check_property_data): Check for int overflow; we cannot use
16245 a wider type due to X limits.

16278 * lisp.h (hash_lookup, hash_put):
16279 * minibuf.c (Ftest_completion):
16280 Use ptrdiff_t for hash table indexes, not int (which is too
16281 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16282 32-bit --with-wide-int hosts).
16284 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16285 Add a FIXME comment about memory leaks.

16293 with outlandish widths.
16294 * character.h (sanitize_tab_width): Rename from sanitize_width,
16295 now that we have two such functions. All uses changed.

16314 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16315 (x_send_scroll_bar_event): Likewise. Check that the size does not
16316 exceed limits imposed by XClientMessageEvent, as well as the usual
16317 ptrdiff_t and size_t limits.
16319 * keyboard.c: Overflow, signedness and related fixes.
16320 (make_lispy_movement): Use same integer type in forward decl
16321 that is used in the definition.
16322 (read_key_sequence, keyremap_step):
16323 Change bufsize argument back to int, undoing my 2011-03-30 change.
16324 We prefer signed types, and int is wide enough here.
16325 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16326 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16327 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16328 length, not size_t. Use ptrdiff_t for index, not int.
16329 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16330 possibility of integer overflow.

16358 Prefer int to unsigned where either will do.
16359 (tiff_handler): New function, combining the cores of the
16360 old tiff_error_handler and tiff_warning_handler.
16361 This function is rewritten to use vsnprintf and thereby avoid
16362 stack buffer overflows. It uses only the features of vsnprintf
16363 that are common to both POSIX and native Microsoft.
16364 (tiff_error_handler, tiff_warning_handler): Use it.
16365 (tiff_load, gif_load, imagemagick_load_image):
16366 Don't assume :index value fits in 'int'.
16367 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

16369 the integer types that MagickCropImage accepts. Don't assume
16370 Vimagemagick_render_type has a nonnegative value. Don't assume
16371 size_t fits in 'long'.
16372 (gs_load): Use printmax_t to print the widest integers possible.

16386 (handle_single_display_spec): If the display spec is of the form
16387 `(space ...)', and specifies display in the text area, return 2
16389 (try_cursor_movement): Check for the need to scroll more
16390 accurately, and prefer exact match for point under bidi.
16391 Don't advance `row' beyond the last row of the window.

16409 buffers, return left-to-right.
16410 (set_cursor_from_row): Consider candidate row a win if its glyph
16411 represents a newline and point is on that newline. Fixes cursor
16412 positioning on the newline at EOL of R2L text within L2R
16413 paragraph, and vice versa.
16414 (try_cursor_movement): Check continued rows, in addition to
16415 continuation rows. Fixes unwarranted scroll when point enters a
16416 continued line of R2L text within an L2R paragraph, or vice versa.
16417 (cursor_row_p): Consider the case of point being equal to
16418 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16419 from the end of a short line to the beginning of a continued line
16420 of R2L text within L2R paragraph.
16421 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

16444 * xdisp.c (redisplay_window): When computing centering_position,
16445 account for the height of the header line. (Bug#8874)
16447 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16448 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16449 candidate is selected by the mouse, and that candidate has a
16450 composed character under the mouse.
16452 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16453 coordinates reported by pos-visible-in-window-p for a composed
16454 character in column zero.
16456 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

16464 composed buffer positions.
16466 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16468 * image.c (gif_load): Don't assume that each subimage has the same
16469 dimensions as the base image. Handle disposal method that is
16470 "undefined" by the gif spec (Bug#9335).
16472 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16474 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16480 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16481 from an Org mode buffer to a Speedbar frame.
16483 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16484 a composition, take its buffer position from IT->cmp_it.charpos.
16485 Fixes cursor positioning at the beginning of a line that begins
16486 with a composed character.
16488 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16490 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16491 character bidirectional type, use STRONG_L instead. Fixes crashes
16492 in a buffer produced by `describe-categories'.
16494 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16495 members before the level stack, so they would be saved and
16496 restored when copying iterator state. Fixes incorrect reordering
16497 around TABs covered by display properties.
16499 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16501 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16506 (internal_condition_case_2, internal_condition_case_n):
16507 Remove unnecessary aborts (Bug#9081).
16509 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16511 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16512 has no `load' handler, try opening the file locally. (Bug#9311)
16514 2011-08-16 Ken Brown <kbrown@cornell.edu>
16516 * gmalloc.c: Expand comment.
16518 2011-08-16 Eli Zaretskii <eliz@gnu.org>

16534 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
16535 in the static heap.
16536 [CYGWIN] (special_realloc): New function.
16537 (_realloc_internal_nolock) [CYGWIN]: Use the new function on

16553 * chartab.c: Improve commentary for the uniprop_table API.
16555 * bidi.c (bidi_paragraph_init): Support zero value of
16556 bidi_ignore_explicit_marks_for_paragraph_level.

16569 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16571 * xdisp.c (move_it_in_display_line_to): Don't invoke
16572 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16573 ppos_it. Fixes vertical cursor motion when line beginning is
16574 covered by an image. (Bug#9296)
16576 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16578 * nsterm.h (ns_run_ascript): Declare.
16579 (NSAPP_DATA2_RUNASSCRIPT): Define.
16581 * nsfns.m (as_script, as_result, as_status): New static variables.
16582 (ns_run_ascript): New function.
16583 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16584 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16585 the event loop. Get status from as_status (Bug#7276).
16587 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16588 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16589 the event loop (Bug#7276).
16591 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16593 * gnutls.c (QCgnutls_bootprop_priority)

16595 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
16596 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
16597 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
16598 (QCgnutls_bootprop_verify_hostname_error)

16614 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16615 (Fnetwork_interface_list): Allocate in increments of bytes instead
16616 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16617 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16619 (struct ifflag_def): notrailers is smart on OSX.
16620 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16621 Get hardware address with getifaddrs if available.
16623 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16625 * xdisp.c (iterate_out_of_display_property): xassert that
16626 IT->position is set to within IT->object's boundaries. Break from
16627 the loop as soon as EOB is reached; avoids infloops in redisplay
16628 when IT->position is set up wrongly due to some bug.
16629 Set IT->current to match the bidi iterator unconditionally.
16630 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16631 entry. Force push_it to save on the stack the current
16632 buffer/string position, to be restored by pop_it. Fix flags in
16633 the iterator structure wrt the object coming from a display
16634 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16635 properties. (Bug#9284)
16637 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16639 * fontset.c (fontset_get_font_group): Add proper type checks.

16652 no-display-properties-and-no-overlays under bidi display.
16653 Set disp_pos in the bidi iterator to avoid searches for display
16654 properties and overlays.
16656 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16658 * editfns.c (Fset_time_zone_rule): Document relationship with the

16667 restore_point_unwind (Bug#5984).
16669 2011-08-07 Juri Linkov <juri@jurta.org>
16671 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16672 to show the arg `TIME' instead of `TIMEVAL'.
16674 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16676 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16677 display property strides EOL and includes a newline, as in
16678 longlines-mode. (Bug#9254)
16679 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16680 word-wrap under bidirectional display. (Bug#9224)
16682 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16683 is non-zero, even if the data buffer is NULL. Fixes a crash in
16684 vertical-motion with longlines-mode. (Bug#9254)
16686 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16688 * bidi.c <bidi_cache_total_alloc>: Now static.
16689 (bidi_initialize): Initialize bidi_cache_total_alloc.
16691 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16694 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16695 amount allocated this far in `bidi_cache_total_alloc'.
16696 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16697 non-zero, only free the data buffer without restoring the cache
16698 contents. All callers changed.
16700 * dispextern.h (bidi_unshelve_cache): Update prototype.
16702 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16703 (move_it_in_display_line, move_it_to)
16704 (move_it_vertically_backward, move_it_by_lines): Replace the call
16705 to xfree to an equivalent call to bidi_unshelve_cache.
16706 (move_it_in_display_line_to): Fix logic of returning
16707 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16709 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16711 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16712 came from a string character with a `cursor' property. (Bug#9229)
16714 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16716 * Makefile.in (LIB_PTHREAD): New variable.
16717 (LIBES): Add LIB_PTHREAD (Bug#9216).
16719 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16720 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16722 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16724 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16726 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16728 * xterm.c (x_find_topmost_parent): New function.
16729 (x_set_frame_alpha): Find topmost parent window with
16730 x_find_topmost_parent and set the property there also (bug#9181).
16731 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16733 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16735 * callproc.c (Fcall_process): Avoid vfork clobbering
16736 the local vars buffer, coding_systems, current_dir.

16744 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16745 so that it is not optimized away.
16747 * xdisp.c (compute_display_string_pos): Remove unused local.
16749 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16751 Fix slow cursor motion and scrolling in large buffers with
16752 selective display, like Org Mode buffers. (Bug#9218)
16754 * dispextern.h (struct bidi_it): New member disp_prop_p.
16756 * xdisp.c: Remove one-slot cache of display string positions.
16757 (compute_display_string_pos): Accept an additional argument
16758 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16759 for a display string or property. If found, set DISP_PROP_P
16762 * bidi.c (bidi_fetch_char): Accept an additional argument
16763 DISP_PROP_P, and pass it to compute_display_string_pos.
16764 Only handle text covered by a display string if DISP_PROP_P is returned
16765 non-zero. All callers of bidi_fetch_char changed.
16767 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16769 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16771 2010-12-03 Don March <don@ohspite.net>
16773 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16774 last character M-[char] is translated to ESC [char] (bug#7541).
16776 2011-08-02 Kenichi Handa <handa@m17n.org>
16778 * lisp.h (uniprop_table): Extern it.
16780 * chartab.c (uniprop_table): Make it non-static.
16782 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16784 * xdisp.c (forward_to_next_line_start): Accept additional argument
16785 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16787 (reseat_at_next_visible_line_start): Use the bidi iterator state
16788 returned by forward_to_next_line_start to restore the state of
16789 it->bidi_it after backing up to previous newline. (Bug#9212)
16791 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16793 * regex.c (re_comp): Protoize.
16794 (re_exec): Fix return type.
16795 (regexec): Fix type of `ret'. (Bug#9203)
16797 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16799 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16800 This is needed if max-image-size is a floating-point number.
16802 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16804 * print.c (print_object): Print empty symbol as ##.

16810 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16811 setting frame foreground color (Bug#9175).
16812 (x_set_background_color): Likewise.

16815 contents (Bug#9176).
16816 (EmacsTooltip -init): Remove bezels and add shadows to
16819 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16820 or scroll bar (Bug#8470).
16822 * nsfont.m (nsfont_open): Remove assignment to voffset and
16823 unnecessary vars hshink, expand, hd, full_height, min_height.
16824 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16826 * nsterm.h (nsfont_info): Remove voffset field.
16828 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16830 Implement strike-through and overline on NextStep (Bug#8863).
16832 * nsfont.m (nsfont_open): Use underline position provided by font,
16833 instead of hard-coded value of 2.
16834 (nsfont_draw): Call ns_draw_text_decoration instead.

16844 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16846 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16849 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16851 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16852 Without this fix, if a signal arrives just after memory fills up,
16853 'malloc' might be invoked reentrantly.
16855 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16856 In other words, assume that every image size is allowed, on non-X
16857 hosts. This assumption is probably wrong, but it lets Emacs compile.
16859 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16861 * regex.c (re_iswctype): Convert return values to boolean.
16863 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16865 * xdisp.c (compute_display_string_pos): Don't use cached display
16866 string position if the buffer had its restriction changed.
16869 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16871 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16873 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16875 Integer signedness and overflow and related fixes. (Bug#9079)
16877 * bidi.c: Integer size and overflow fixes.
16878 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16879 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16880 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16881 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16882 (bidi_find_other_level_edge):
16883 Use ptrdiff_t instead of EMACS_INT where either will do.
16884 This works better on 32-bit hosts configured --with-wide-int.
16885 (bidi_cache_ensure_space): Check for size-calculation overflow.
16886 Use % rather than repeated addition, for better worst-case speed.
16887 Don't set bidi_cache_size until after xrealloc returns, because it
16889 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16890 (bidi_cache_ensure_space): Also check that the bidi cache size
16891 does not exceed that of the largest Lisp string or buffer. See Eli
16892 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16894 * alloc.c (__malloc_size_t): Remove.
16895 All uses replaced by size_t. See Andreas Schwab's note
16896 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16898 * image.c: Improve checking for integer overflow.
16899 (check_image_size): Assume that f is nonnull, since
16900 it is always nonnull in practice. This is one less thing to
16901 worry about when checking for integer overflow later.
16902 (x_check_image_size): New function, which checks for integer
16903 overflow issues inside X.
16904 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16905 This removes the need for a memory_full check.
16906 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16907 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16908 (xbm_read_bitmap_data): Change locals back to 'int', since
16909 their values must fit in 'int'.
16910 (xpm_load_image, png_load, tiff_load):
16911 Invoke x_create_x_image_and_pixmap earlier,
16912 to avoid much needless work if the image is too large.
16913 (tiff_load): Treat overly large images as if
16914 x_create_x_image_and_pixmap failed, not as malloc failures.
16915 (gs_load): Use x_check_image_size.
16917 * gtkutil.c: Omit integer casts.
16918 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16919 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16921 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16923 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16924 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16925 would wrongly return t on a 64-bit host.
16927 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16928 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16929 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16930 and therefore cause GCC to emit a bogus diagnostic in some cases.
16932 * image.c: Integer signedness and overflow and related fixes.
16933 This is not an exhaustive set of fixes, but it's time to
16934 record what I've got.
16935 (lookup_pixel_color, check_image_size): Remove redundant decls.
16936 (check_image_size): Don't assume that arbitrary EMACS_INT values
16937 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16938 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16939 (tiff_load, imagemagick_load_image):
16940 Check for overflow in size calculations.
16941 (x_create_x_image_and_pixmap): Remove unnecessary test for
16942 xmalloc returning NULL; that can't happen.
16943 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16944 (xpm_color_bucket): Use better integer hashing function.
16945 (xpm_cache_color): Don't possibly over-allocate memory.
16946 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16947 (gif_memory_source):
16948 Use ptrdiff_t, not int or size_t, to record sizes.
16949 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16950 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16951 either works, as we prefer signed integers.
16952 (tiff_read_from_memory, tiff_write_from_memory):
16953 Return tsize_t, not size_t, since that's what the TIFF API wants.
16954 (tiff_read_from_memory): Don't fail simply because the read would
16955 go past EOF; instead, return a short read.
16956 (tiff_load): Omit no-longer-needed casts.
16957 (Fimagemagick_types): Don't assume size fits into 'int'.
16959 Improve hashing quality when configured --with-wide-int.
16960 * fns.c (hash_string): New function, taken from sxhash_string.
16961 Do not discard information about ASCII character case; this
16962 discarding is no longer needed.
16963 (sxhash-string): Use it. Change sig to match it. Caller changed.
16964 * lisp.h: Declare it.
16965 * lread.c (hash_string): Remove, since we now use fns.c's version.
16966 The fns.c version returns a wider integer if --with-wide-int is
16967 specified, so this should help the quality of the hashing a bit.
16969 * emacs.c: Integer overflow minor fix.
16970 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16971 Define only if GNU_LINUX.
16972 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16974 * dispnew.c: Integer signedness and overflow fixes.
16975 Remove unnecessary forward decls, that were a maintenance hassle.
16976 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16978 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16979 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16980 (prepare_desired_row, line_draw_cost):
16981 Use int, not unsigned, where either works.
16982 (save_current_matrix, restore_current_matrix):
16983 Use ptrdiff_t, not size_t, where either works.
16984 (init_display): Check for overflow more accurately, and without
16985 relying on undefined behavior.
16987 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16988 Remove, replacing with the new symbols in lisp.h. All uses changed.
16989 * fileio.c (make_temp_name):
16990 * filelock.c (lock_file_1, lock_file):
16991 * xdisp.c (message_dolog):
16992 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16993 Use pMd etc. instead.
16994 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16995 replacing the pWIDE etc. symbols removed from editfns.c.
16997 * keyboard.h (num_input_events): Now uintmax_t.
16998 This is (very slightly) less likely to mess up due to wraparound.
17001 * buffer.c: Integer signedness fixes.
17002 (alloc_buffer_text, enlarge_buffer_text):
17003 Use ptrdiff_t rather than size_t when either will do, as we prefer
17006 * alloc.c: Integer signedness and overflow fixes.
17007 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17008 (__malloc_size_t): Default to size_t, not to int.
17009 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17010 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17011 Prefer ptrdiff_t to size_t when either would do, as we prefer
17013 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17014 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17015 Now const. Initialize with values that are in range even if char
17017 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17018 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17019 These functions do the right thing with sizes > 2**32.
17020 (check_depth): Now ptrdiff_t, not int.
17021 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17022 Adjust to new way of storing sizes. Check for size overflow bugs
17024 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17025 slightly wrong anyway, as it missed one instance of
17026 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17027 (refill_memory_reserve): Omit needless cast to size_t.
17028 (mark_object_loop_halt): Mark as externally visible.
17030 * xselect.c: Integer signedness and overflow fixes.
17031 (Fx_register_dnd_atom, x_handle_dnd_message):
17032 Use ptrdiff_t, not size_t, since we prefer signed.
17033 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17034 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17035 x_dnd_atoms_size and x_dnd_atoms_length.
17037 * doprnt.c: Prefer signed to unsigned when either works.
17039 * doprnt.c (doprnt):
17041 * xdisp.c (vmessage):
17042 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17043 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17044 prefer signed arithmetic to avoid comparison confusion.
17045 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17046 but is a bit tricky.
17048 Assume freestanding C89 headers, string.h, stdlib.h.
17049 * data.c, doprnt.c, floatfns.c, print.c:
17050 Include float.h unconditionally.
17051 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17052 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17053 * regex.c: Likewise for stddef.h, string.h.
17054 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17055 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17056 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17057 (STDC_HEADERS): Remove obsolete defines.
17058 * sysdep.c: Include limits.h unconditionally.
17060 Assume support for memcmp, memcpy, memmove, memset.
17061 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17062 * regex.c (memcmp, memcpy):
17063 Remove; we assume C89 now.
17065 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17066 (__malloc_safe_bcopy): Remove; no longer needed.
17068 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17069 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17070 well either way, and we prefer signed to unsigned.
17072 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17074 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17075 closes the connection while we're reading (bug#9182).
17077 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17079 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17080 are specified (Bug#9168).
17082 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17084 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17085 Found by GCC static checking and --with-wide-int on a 32-bit host.
17087 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17089 * xdisp.c (compute_display_string_pos): Fix logic of caching
17090 previous display string position. Initialize cached_prev_pos to
17091 -1. Fixes slow-down at the beginning of a buffer.
17093 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17095 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17096 for attrs[LFACE_FONTSET_INDEX].
17098 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17100 * xml.c (parse_region): Remove unused local
17101 that was recently introduced.
17103 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17105 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17106 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17108 * xdisp.c (move_it_in_display_line_to): Record the best matching
17109 position for TO_CHARPOS while scanning the line, and restore it on
17110 exit if none of the characters scanned was an exact match.
17111 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17112 when exact match is impossible due to invisible text, and the
17113 lines are truncated.
17115 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17117 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17120 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17122 Fix a significant slow-down of cursor motion with C-n, C-p,
17123 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17124 auto-repeat under bidi redisplay in fontified buffers.
17125 * xdisp.c (compute_stop_pos_backwards): New function.
17126 (next_element_from_buffer): Call compute_stop_pos_backwards to
17127 find a suitable prev_stop when we find ourselves before
17129 (reseat): Don't look for prev_stop, as that could mean a very long
17131 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17132 <cached_disp_overlay_modiff>: Cache for last found display string
17134 (compute_display_string_pos): Return the cached position if asked
17135 about the same buffer in the same area of character positions, and
17136 the buffer wasn't changed since the time the display string
17137 position was cached.
17139 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17141 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17142 is an integer, which is important for empty lines. (Bug#9149)
17144 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17146 * frame.c (Fmodify_frame_parameters): In tty case, update the
17147 default face if necessary (Bug#4238).
17149 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17151 * editfns.c (Fstring_to_char): No need to explain what a character
17152 is in the docstring (Bug#6576).
17154 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17156 * xml.c (parse_region): Make sure we always return a tree.
17158 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17160 * xml.c (parse_region): If a document contains only comments,
17163 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17165 * xml.c (make_dom): Return comments, too.
17167 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17170 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17171 and the surrounding thread.
17172 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17173 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17174 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17176 * s/openbsd.h (BROKEN_SIGIO): Define.
17177 * unexelf.c (unexec) [__OpenBSD__]:
17178 Don't update the .mdebug section of the Alpha COFF symbol table.
17180 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17182 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17185 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17187 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17188 This fixes some race conditions on the permissions of any newly
17191 * alloc.c (valid_pointer_p): Use pipe, not open.
17192 This fixes some permissions issues when debugging.
17194 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17195 If fchown fails to set both uid and gid, try to set just gid,
17196 as that is sometimes allowed. Adjust the file's mode to eliminate
17197 setuid or setgid bits that are inappropriate if fchown fails.
17199 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17201 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17202 to compare Lisp_Objects.
17203 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17204 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17205 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17207 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17209 * lread.c (read_integer): Unread even EOF character.
17210 (read1): Likewise. Properly record start position of symbol.
17212 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17213 symbol character follows.
17215 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17217 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17218 This works around a problem with the previous change to Fcopy_file.
17219 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17220 and without this change, GCC might complain about discarding
17221 fchown's return value.
17223 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17225 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17227 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17229 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17231 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17233 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17234 it's used from the C level.
17236 * process.c: Use the same condition for POLL_FOR_INPUT in both
17237 keyboard.c and process.c (bug#1858).
17239 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17241 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17242 (Fgnutls_boot): Use it.
17244 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17246 * doc.c (Fsubstitute_command_keys): Revert last change.
17248 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17250 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17251 quotes the next character, and doesn't affect other longer
17252 sequences (bug#8935).
17254 * lread.c (syms_of_lread): Clarify that is isn't only
17255 `eval-buffer' and `eval-defun' that's affected by
17256 `lexical-binding' (bug#8460).
17258 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17260 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17261 bidi redisplay when a line includes both an image and is truncated.
17263 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17265 Fix minor problems found by static checking.
17266 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17267 (elsz): Now a signed constant, not a size_t var. We prefer signed
17268 types to unsigned, to avoid integer comparison confusion. Without
17269 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17270 "cannot optimize loop, the loop counter may overflow", a symptom
17272 * indent.c (Fvertical_motion): Mark locals as initialized.
17273 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17275 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17277 * search.c (Fre_search_backward): Mention `case-fold-search' in
17278 all the re_search_* functions (bug#8138).
17280 * keyboard.c (Fopen_dribble_file): Document when the file is
17283 2011-07-14 Eli Zaretskii <eliz@gnu.org>
17285 * bidi.c (bidi_dump_cached_states): Fix format of displaying
17288 Support bidi reordering of display and overlay strings.
17289 * xdisp.c (compute_display_string_pos)
17290 (compute_display_string_end): Accept additional argument STRING.
17291 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
17292 (reseat_to_string): Initialize bidi_it->string.s and
17293 bidi_it->string.schars.
17294 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
17295 NULL (avoids a crash in bidi_paragraph_init).
17296 Initialize itb.string.lstring.
17297 (init_iterator): Call bidi_init_it only of a valid
17298 buffer position was specified. Initialize paragraph_embedding to
17300 (reseat_to_string): Initialize the bidi iterator.
17301 (display_string): If we need to ignore text properties of
17302 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17303 original value of -1 will not work with bidi.)
17304 (compute_display_string_pos): First arg is now struct
17305 `text_pos *'; all callers changed. Support display properties on
17307 (compute_display_string_end): Support display properties on Lisp
17309 (init_iterator, reseat_1, reseat_to_string): Initialize the
17310 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17311 when iterating on a string not from display properties).
17312 (compute_display_string_pos, compute_display_string_end):
17313 Fix calculation of the object to scan. Fixes an error when using
17315 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17316 base_level_stop; instead, set base_level_stop to BEGV.
17317 Fixes crashes in vertical-motion.
17318 (next_element_from_buffer): Improve commentary for when
17319 the iterator is before prev_stop.
17320 (init_iterator): Initialize bidi_p from the default value of
17321 bidi-display-reordering, not from buffer-local value. Use the
17322 buffer-local value only if initializing for buffer iteration.
17323 (handle_invisible_prop): Support invisible properties on strings
17324 that are being bidi-reordered.
17325 (set_iterator_to_next): Support bidi reordering of C strings and
17327 (next_element_from_string): Support bidi reordering of Lisp
17329 (handle_stop_backwards): Support Lisp strings as well.
17330 (display_string): Support display of R2L glyph rows.
17331 Use IT_STRING_CHARPOS when displaying from a Lisp string.
17332 (init_iterator): Don't initialize it->bidi_p for strings
17334 (reseat_to_string): Initialize it->bidi_p for strings here.
17335 (next_element_from_string, next_element_from_c_string)
17336 (next_element_from_buffer): Add xassert's for correspondence
17337 between IT's object being iterated and it->bidi_it.string
17339 (face_before_or_after_it_pos): Support bidi iteration.
17340 (next_element_from_c_string): Handle the case of the first string
17341 character that is not the first one in the visual order.
17342 (get_visually_first_element): New function, refactored from common
17343 parts of next_element_from_buffer, next_element_from_string, and
17344 next_element_from_c_string.
17345 (tool_bar_lines_needed, redisplay_tool_bar)
17346 (display_menu_bar): Force left-to-right direction. Add a FIXME
17347 comment for making that be controlled by a user option.
17348 (push_it, pop_it): Save and restore the state of the
17349 bidi iterator. Save and restore the bidi_p flag.
17350 (pop_it): Iterate out of display property for string iteration as
17352 (iterate_out_of_display_property): Support iteration over strings.
17353 (handle_single_display_spec): Set up it->bidi_it for iteration
17354 over a display string, and call bidi_init_it.
17355 (handle_single_display_spec, next_overlay_string)
17356 (get_overlay_strings_1, push_display_prop): Set up the bidi
17357 iterator for displaying display or overlay strings.
17358 (forward_to_next_line_start): Don't use the shortcut if

17795 * alloc.c (mark_buffer):
17796 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
17797 (clone_per_buffer_values): Don't assume that
17798 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
17799 This isn't true in general, and it's particularly not true
17800 if Emacs is configured with --with-wide-int.
17801 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17802 New macros, used in the buffer.c change.
17804 2011-07-05 Jan Djärv <jan.h.d@swipnet.se>

17808 (dpyinfo_valid, store_font_name_changed, map_tool_bar_style)
17809 (store_tool_bar_style_changed): New functions.
17810 (store_monospaced_changed): Add comment. Call dpyinfo_valid.
17811 (struct xsettings): Move font inside HAVE_XFT.
17812 (GSETTINGS_TOOL_BAR_STYLE, GSETTINGS_FONT_NAME): New defines.
17813 (GSETTINGS_MONO_FONT): Rename from SYSTEM_MONO_FONT.
17814 Move inside HAVE_XFT.
17815 (something_changed_gsettingsCB): Rename from something_changedCB.
17816 Check for changes in GSETTINGS_TOOL_BAR_STYLE and GSETTINGS_FONT_NAME

17822 (parse_settings): Move check for font inside HAVE_XFT.
17823 (read_settings, apply_xft_settings): Add comment.
17824 (read_and_apply_settings): Add comment. Call map_tool_bar_style and
17825 store_tool_bar_style_changed. Move check for font inside HAVE_XFT and
17826 call store_font_name_changed.
17827 (xft_settings_event): Add comment.
17828 (init_gsettings): Add comment. Get values for GSETTINGS_TOOL_BAR_STYLE
17829 and GSETTINGS_FONT_NAME. Move check for fonts within HAVE_XFT.

17836 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
17838 Random fixes. E.g., (random) never returned negative values.
17839 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17840 subseconds part to the entropy, as that's a bit more random.
17841 Prefer signed to unsigned, since the signedness doesn't matter and
17842 in general we prefer signed. When given a limit, use a
17843 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17844 latter isn't right if USE_2_TAGS_FOR_INTS.
17845 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17846 not 0..VALMASK. Don't discard "excess" bits that random () returns.
17848 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
17850 * textprop.c (text_property_stickiness):
17851 Obey Vtext_property_default_nonsticky.
17852 (syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.
17853 * w32fns.c (syms_of_w32fns):

17856 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
17858 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17859 This is more efficient than Ffile_directory_p and avoids a minor race.
17861 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17863 * buffer.c (Foverlay_put): Say what the return value is
17866 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17867 is a directory before asking whether to use the file name
17869 (barf_or_query_if_file_exists): Make the "File is a directory"
17870 error be more correct.
17872 * fns.c (Frequire): Remove the mention of the .gz files, since
17873 that's installation-specific, but keep the mention of
17874 `get-load-suffixes'.
17876 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
17878 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17884 (syms_of_gnutls): Remove duplicate DEFSYM for
17885 Qgnutls_bootprop_verify_hostname_error, an error for
17886 Qgnutls_bootprop_verify_error (which is no longer used).
17888 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17889 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17890 Also (re)move comments that are misplaced or no longer relevant.
17892 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17894 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).
17896 2011-07-03 Chong Yidong <cyd@stupidchicken.com>
17898 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
17899 and background color parameters if they have been changed.

17919 * lread.c (syms_of_lread): Mention single symbols defined by
17920 `defvar' or `defconst' (bug#7154).
17922 * fns.c (Frequire): Mention .el.gz files (bug#7314).
17923 (Frequire): Mention get-load-suffixes.

17953 (syms_of_keymap): Defsubr make-composed-keymap.
17954 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

17991 * eval.c (struct backtrace): Simplify and port the data structure.
17992 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17993 signed bit field, as this assumption is not portable and it makes
17994 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17995 "char debug_on_exit : 1" as this is not portable either; instead,
17996 use the portable "unsigned int debug_on_exit : 1". Remove unused
17997 member evalargs. Remove obsolete comments about cc bombing out.
17999 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18232 on undefined behavior with wrong number of arguments.
18233 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18234 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18235 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18236 since we're not interested in debugging glyphs with old libraries.
18237 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18238 GCC 4.6.0's static checking.
18240 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18242 Integer overflow and signedness fixes (Bug#8873).
18243 A few related buffer overrun fixes, too.
18245 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
18247 * dispextern.h (struct face.stipple):
18248 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
18249 (x_bitmap_mask, x_allocate_bitmap_record)
18250 (x_create_bitmap_from_data, x_create_bitmap_from_file)
18251 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
18252 (x_create_bitmap_from_xpm_data):
18253 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
18254 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
18256 * xfaces.c (load_pixmap):
18257 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
18258 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18259 (.bitmaps_last, struct x_output.icon_bitmap):
18260 Use ptrdiff_t, not int, for bitmap indexes.
18261 (x_allocate_bitmap_record): Check for size overflow.
18262 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18264 Use ptrdiff_t, not int, for overlay counts.
18265 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18266 * editfns.c (overlays_around, get_pos_property):
18267 * textprop.c (get_char_property_and_overlay):
18268 * xdisp.c (next_overlay_change, note_mouse_highlight):
18269 * xfaces.c (face_at_buffer_position):
18270 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18271 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18272 (Fnext_overlay_change, Fprevious_overlay_change)
18273 (mouse_face_overlay_overlaps, Foverlays_in):
18274 Use ptrdiff_t, not int, for sizes.
18275 (overlays_at, overlays_in): Check for size-calculation overflow.
18277 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18279 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18280 (x_session_initialize): Do not assume string length fits in int.
18282 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18283 This is unlikely, but can occur if DPI is outlandish.
18285 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18286 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18288 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18289 * xrdb.c (magic_file_p, search_magic_path):
18290 Omit last arg SUFFIX; it was always 0. All callers changed.
18291 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18293 * xfont.c (xfont_match): Avoid need for strlen.
18295 * xfns.c: Don't assume strlen fits in int.
18296 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18298 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18299 not unsigned long, as we prefer signed integers. All callers changed.
18300 Detect integer overflow in repeat count.
18301 (message_dolog): Don't assume print length fits in 39 bytes.
18302 (display_mode_element): Don't assume strlen fits in int.
18304 * termcap.c: Don't assume sizes fit in int and never overflow.
18305 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18306 (gobble_line): Check for size-calculation overflow.
18308 * minibuf.c (Fread_buffer):
18309 * lread.c (intern, intern_c_string):
18310 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18311 Don't assume string length fits in int.
18313 * keyboard.c (parse_tool_bar_item):
18314 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18316 * font.c: Don't assume string length fits in int.
18317 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18318 Use ptrdiff_t, not int.
18319 (font_intern_prop): Don't assume string length fits in int.
18320 Don't assume integer property fits in fixnum.
18321 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18323 * filelock.c: Fix some buffer overrun and integer overflow issues.
18324 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18325 Reformulate so as not to need the command string.
18326 Invoke gzip -cd rather than gunzip, as it's more portable.
18327 (lock_info_type, lock_file_1, lock_file):
18328 Don't assume pid_t and time_t fit in unsigned long.
18329 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18330 (current_lock_owner): Prefer signed type for sizes.
18331 Use memcpy, not strncpy, where memcpy is what is really wanted.
18332 Don't assume (via atoi) that time_t and pid_t fit in int.
18333 Check for time_t and/or pid_t out of range, e.g., via a network share.
18334 Don't alloca where an auto var works fine.
18336 * fileio.c: Fix some integer overflow issues.
18337 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18338 Don't assume string length fits in int.
18339 (directory_file_name): Don't assume string length fits in long.
18340 (make_temp_name): Don't assume pid fits in int, or that its print
18341 length is less than 20.
18343 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18345 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18347 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18349 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18350 We prefer signed integers, even for size calculations.
18352 * emacs.c: Don't assume string length fits in 'int'.
18353 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18354 (main): Don't invoke strlen when not needed.
18356 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18357 (XD_DEBUG_MESSAGE): Don't waste a byte.
18359 * callproc.c (getenv_internal_1, getenv_internal)
18360 (Fgetenv_internal):
18361 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18363 * lread.c (invalid_syntax): Omit length argument.
18364 All uses changed. This doesn't fix a bug, but it simplifies the
18365 code away from its former Hollerith-constant appearance, and it's
18366 one less 'int' to worry about when looking at integer-overflow issues.
18367 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18369 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18370 This didn't break anything, but it didn't help either.
18371 It's confusing to put a bogus integer in a place where the actual
18372 value does not matter.
18373 (LIST_END_P): Remove unused macro and its bogus comment.
18374 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18376 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18377 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18379 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18380 We prefer signed types, and the value cannot exceed the EMACS_INT
18381 range anyway (because otherwise the length would not be representable).
18382 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18383 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18384 This avoids a GCC warning when WIDE_EMACS_INT.
18386 * indent.c (sane_tab_width): New function.
18387 (current_column, scan_for_column, Findent_to, position_indentation)
18388 (compute_motion): Use it. This is just for clarity.
18389 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18391 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18393 * lisp.h (lint_assume): New macro.
18394 * composite.c (composition_gstring_put_cache):
18395 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18397 * editfns.c, insdel.c:
18398 Omit unnecessary forward decls, to simplify future changes.
18400 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18402 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18404 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18405 Use much-faster test for byte-length change.
18406 Don't assume string byte-length fits in 'int'.
18407 Check that character arg fits in 'int'.
18408 (mapcar1): Declare byte as byte, for clarity.
18410 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18412 * fns.c (concat): Catch string overflow earlier.
18413 Do not rely on integer wraparound.
18415 * dispextern.h (struct it.overlay_strings_charpos)
18416 (struct it.selective): Now EMACS_INT, not int.
18417 * xdisp.c (forward_to_next_line_start)
18418 (back_to_previous_visible_line_start)
18419 (reseat_at_next_visible_line_start, next_element_from_buffer):
18420 Don't arbitrarily truncate the value of 'selective' to int.
18422 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18424 * composite.c: Don't truncate sizes to 'int'.
18425 (composition_gstring_p, composition_reseat_it)
18426 (composition_adjust_point): Use EMACS_INT, not int.
18427 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18428 not EMACS_UINT, for indexes.
18430 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18432 * buffer.c: Include <verify.h>.
18433 (struct sortvec.priority, struct sortstr.priority):
18434 Now EMACS_INT, not int.
18435 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18436 (struct sortstr.size, record_overlay_string)
18437 (struct sortstrlist.size, struct sortlist.used):
18438 Don't truncate size to int.
18439 (record_overlay_string): Check for size-calculation overflow.
18440 (init_buffer_once): Check at compile-time, not run-time.
18442 2011-06-22 Jim Meyering <meyering@redhat.com>
18444 Don't leak an XBM-image-sized buffer
18445 * image.c (xbm_load): Free the image buffer after using it.
18447 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18450 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18451 that Sun C diagnosed.
18452 * fns.c (secure_hash): Fix pointer signedness issue.
18453 * intervals.c (static_offset_intervals): New function.
18454 (offset_intervals): Use it.
18456 2011-06-21 Leo Liu <sdl.web@gmail.com>
18459 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18462 * fns.c (secure_hash): Rename from crypto_hash_function and change
18463 the first arg to accept symbols.
18464 (Fsecure_hash): New primitive.
18465 (syms_of_fns): New symbols.
18467 2011-06-20 Deniz Dogan <deniz@dogan.se>
18469 * process.c (Fset_process_buffer): Clarify return value in
18472 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18474 * dispnew.c (add_window_display_history): Use BVAR.
18476 * xdisp.c (debug_method_add): Use BVAR.
18477 (check_window_end, dump_glyph_matrix, dump_glyph)
18478 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18480 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18483 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18484 check till after the cache is created in init_frame_faces.
18486 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18488 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18490 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18492 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18493 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18494 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18496 Improve buffer-overflow checking (Bug#8873).
18497 * fileio.c (Finsert_file_contents):
18498 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18499 Remove the old (too-loose) buffer overflow checks.
18500 They weren't needed, since make_gap checks for buffer overflow.
18501 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18502 The old code merely checked for Emacs fixnum overflow, and relied
18503 on undefined (wraparound) behavior. The new code avoids undefined
18504 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18506 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18507 Tune. Don't use wider integers than needed. Don't use alloca.
18508 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18510 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18512 * insdel.c, lisp.h (buffer_overflow): New function.
18513 (insert_from_buffer_1, replace_range, replace_range_2):
18514 * insdel.c (make_gap_larger):
18515 * editfns.c (Finsert_char):
18516 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18518 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18520 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18522 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18524 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18525 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18527 * fileio.c: Don't assume EMACS_INT fits in off_t.
18528 (emacs_lseek): New static function.
18529 (Finsert_file_contents, Fwrite_region): Use it.
18530 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18532 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18534 * fns.c: Don't overflow int when computing a list length.
18535 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18536 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18537 truncation on 64-bit hosts. Check for QUIT every
18538 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18539 faster and is responsive enough.
18540 (Flength): Report an error instead of overflowing an integer.
18541 (Fsafe_length): Return a float if the value is not representable
18542 as a fixnum. This shouldn't happen except in contrived situations.
18543 (Fnthcdr, Fsort): Don't assume list length fits in int.
18544 (Fcopy_sequence): Don't assume vector length fits in int.
18546 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18547 (header_size, word_size): New constants.
18548 (allocate_vectorlike): Don't check size overflow here.
18549 (allocate_vector): Check it here instead, since this is the only
18550 caller of allocate_vectorlike that could cause overflow.
18551 Check that the new vector's length is representable as a fixnum.
18553 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18554 The previous code was bogus. For example, next_almost_prime (32)
18555 returned 39, which is undesirable as it is a multiple of 3; and
18556 next_almost_prime (24) returned 25, which is a multiple of 5 so
18557 why was the code bothering to check for multiples of 7?
18559 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18561 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18563 Variadic C functions now count arguments with ptrdiff_t.
18564 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18565 Back then I didn't know that the Emacs coding style prefers signed int.
18566 Also, in the meantime I found a few more instances where arguments
18567 were being counted with int, which may truncate counts on 64-bit
18568 machines, or EMACS_INT, which may be unnecessarily wide.
18569 * lisp.h (struct Lisp_Subr.function.aMANY)
18570 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18571 Arg counts are now ptrdiff_t, not size_t.
18572 All variadic functions and their callers changed accordingly.
18573 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18574 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18575 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18576 * callint.c (Fcall_interactively): Check arg count for overflow,
18577 to avoid potential buffer overrun. Use signed char, not 'int',
18578 for 'varies' array, so that we needn't bother to check its size
18579 calculation for overflow.
18580 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18581 * eval.c (apply_lambda):
18582 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18583 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18584 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18586 * callint.c (Fcall_interactively): Don't use index var as event count.
18588 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18589 * mem-limits.h (SIZE): Remove; no longer used.
18591 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18593 Remove unnecessary casts.
18594 * xterm.c (x_term_init):
18595 * xfns.c (x_set_border_pixel):
18596 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18597 These aren't needed now that we assume ANSI C.
18599 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18600 It's more likely to cause problems (due to unsigned overflow)
18603 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18605 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18607 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18609 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18611 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18613 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18615 GLYPH_CODE_FACE returns EMACS_INT, not int.
18616 * dispextern.h (merge_faces):
18617 * xfaces.c (merge_faces):
18618 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18619 Don't assume EMACS_INT fits in int.
18621 * character.h (CHAR_VALID_P): Remove unused parameter.
18622 * fontset.c, lisp.h, xdisp.c: All uses changed.
18624 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18626 * fns.c (concat): Minor tuning based on overflow analysis.
18627 This doesn't fix any bugs. Use int to hold character, instead
18628 of constantly refetching from Emacs object. Use XFASTINT, not
18629 XINT, for value known to be a character. Don't bother comparing
18630 a single byte to 0400, as it's always less.
18632 * floatfns.c (Fexpt):
18633 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18635 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18638 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18640 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18641 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18642 incorrectly succeed when S was a string, because 4294967386 was
18643 truncated before it was used.
18645 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18646 Otherwise, an out-of-range integer could cause undefined behavior
18649 * composite.c: Use int, not EMACS_INT, for characters.
18650 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18651 EMACS_INT, for values that are known to be in character range.
18652 This doesn't fix any bugs but is the usual style inside Emacs and
18653 may generate better code on 32-bit machines.
18655 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18656 This is for reasons similar to the recent CHAR_STRING fix.
18657 * charset.c (Fencode_char): Check that character arg is actually
18658 a character. Pass an int to ENCODE_CHAR.
18659 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18660 wider than 'int', as a compile-time check to prevent future regressions
18663 * character.c (char_string): Remove unnecessary casts.
18665 Make sure a 64-bit char is never passed to CHAR_STRING.
18666 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18667 by silently ignoring the top 32 bits, allowing some values
18668 that were far too large to be valid characters.
18669 * character.h: Include <verify.h>.
18670 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18671 arguments are no wider than unsigned, as a compile-time check
18672 to prevent future regressions in this area.
18674 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18675 (Fsubst_char_in_region):
18677 * xdisp.c (decode_mode_spec_coding):
18678 Adjust to CHAR_STRING's new requirement.
18679 * editfns.c (Finsert_char, Fsubst_char_in_region):
18680 * fns.c (concat): Check that character args are actually
18681 characters. Without this test, these functions did the wrong
18682 thing with wildly out-of-range values on 64-bit hosts.
18684 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18685 These casts should not be needed on 32-bit hosts, either.
18686 * keyboard.c (read_char):
18687 * lread.c (Fload): Remove casts to unsigned.
18689 * lisp.h (UNSIGNED_CMP): New macro.
18690 This fixes comparison bugs on 64-bit hosts.

18692 * casefiddle.c (casify_object):
18693 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18694 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18695 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18696 * dispextern.h (FACE_FROM_ID):
18697 * keyboard.c (read_char): Use UNSIGNED_CMP.
18699 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18700 not to EMACS_INT, to avoid GCC warning.
18702 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18704 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18705 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18706 isn't needed on 32-bit machines.
18708 * buffer.c (Fgenerate_new_buffer_name):
18709 Use EMACS_INT for count, not int.
18710 (advance_to_char_boundary): Return EMACS_INT, not int.

18729 (total_free_floats, total_floats, total_free_intervals)
18730 (total_intervals, total_strings, total_free_strings):
18731 Now EMACS_INT, not int. All uses changed.
18732 (Fgarbage_collect): Compute overall total using a double, so that
18733 integer overflow is less likely to be a problem. Check for overflow
18734 when converting back to an integer.
18735 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18736 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18737 These were 'int' variables that could overflow on 64-bit hosts;
18738 they were never used, so remove them instead of repairing them.
18739 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18740 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18741 Previously, this ceilinged at INT_MAX, but that doesn't work on
18743 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18745 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18746 (allocate_vectorlike): Check for ptrdiff_t overflow.
18747 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18748 when a (possibly-narrower) signed value would do just as well.
18749 We prefer using signed arithmetic, to avoid comparison confusion.
18751 * alloc.c: Catch some string size overflows that we were missing.
18752 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18753 for convenience in STRING_BYTES_MAX.
18754 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18755 The definition here is exact; the one in lisp.h was approximate.
18756 (allocate_string_data): Check for string overflow. This catches
18757 some instances we weren't catching before. Also, it catches
18758 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18759 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18760 and ptrdiff_t and EMACS_INT are both 64 bits.
18762 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18763 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18764 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18766 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18768 * alloc.c (Fmake_string): Check for out-of-range init.

19341 instead of using explicit *_CHAR codes.
19342 (bidi_resolve_explicit, bidi_resolve_weak):

19351 (bidi_level_of_next_char): Don't try to lookup the cache for the
19352 next/previous character if nothing is cached there yet, or if we
19353 were just reseat()'ed to a new position.
19355 * xdisp.c (set_cursor_from_row): Set start and stop points
19356 according to the row's direction when priming the loop that looks
19357 for the glyph on which to display cursor.
19358 (single_display_spec_intangible_p): Function deleted.
19359 (display_prop_intangible_p): Reimplement to call
19360 handle_display_spec instead of single_display_spec_intangible_p.
19361 Accept 3 additional arguments needed by handle_display_spec.
19362 This fixes incorrect cursor motion across display property with complex
19363 values: lists, `(when COND...)' forms, etc.

19371 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19372 value of a `display' property is a "replacing spec".
19373 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19374 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19375 the display property, but just return a value indicating whether
19376 the display property will replace the characters it covers.
19377 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19378 frame_window_p members of struct bidi_it.
19379 (compute_display_string_pos, compute_display_string_end):

19404 * gnutls.c: Use Emacs's memory allocators.
19405 Without this change, the gnutls library would invoke malloc etc.
19406 directly, which causes problems on non-SYNC_INPUT hosts, and which
19407 runs afoul of improving memory_full behavior. (Bug#8761)
19408 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19409 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19410 xfree instead of the default malloc, realloc, free.
19411 (Fgnutls_boot): No need to check for memory allocation failure,
19412 since xmalloc does that for us.
19414 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

19434 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19435 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19436 * alloc.c (allocate_vectorlike):
19437 Check for overflow in vector size calculations.
19438 * ccl.c (ccl_driver):
19439 Check for overflow when converting EMACS_INT to int.

19441 need to be updated by these changes.
19442 * fns.c (make_hash_table, maybe_resize_hash_table):
19443 Check for integer overflow with large hash tables.
19444 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19445 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19446 (SXHASH_REDUCE): New macro.
19447 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19448 Use it instead of discarding useful hash info with large hash values.
19449 (sxhash_float): New function.
19450 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19451 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19452 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19453 Rewrite to use FIXNUM_BITS, as this simplifies things.
19454 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19455 Adjust signatures to match updated version of code.
19456 (consing_since_gc): Now EMACS_INT, since a single hash table can
19457 use more than INT_MAX bytes.

19506 Make it possible to run ./temacs.
19508 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19509 syms_of_callproc does the same thing. Remove test for
19510 "initialized", do it in the caller.

19541 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19543 Minor fixes prompted by GCC 4.6.0 warnings.
19545 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19547 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19548 (x_clipboard_manager_save_all): Move extern decl to ...
19549 * xterm.h: ... here, so that it can be checked for consistency.
19551 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19553 * xselect.c (x_clipboard_manager_save_frame)
19554 (x_clipboard_manager_save_all): New functions.
19555 (Fx_clipboard_manager_save): Lisp function deleted.
19557 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19558 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19560 * xterm.h: Update prototype.
19562 2011-05-28 William Xu <william.xwl@gmail.com>
19564 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19565 exiting (Bug#8239).
19567 2011-05-28 Jim Meyering <meyering@redhat.com>
19569 Avoid a sign-extension bug in crypto_hash_function.
19570 * fns.c (to_uchar): Define.
19571 (crypto_hash_function): Use it to convert some newly-signed
19572 variables to unsigned, to avoid sign-extension bugs. For example,
19573 without this change, (md5 "truc") would evaluate to
19574 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19575 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19576 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19578 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19580 Integer overflow fixes.
19582 * dbusbind.c: Serial number integer overflow fixes.
19583 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19584 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19585 to hold a serial number that is too large for a fixnum.
19586 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19587 Check for serial numbers out of range. Decode any serial number
19588 that was so large that it became a float. (Bug#8722)
19590 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19591 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19592 Use XFASTINT rather than XUINT when numbers are nonnegative.
19593 (xd_append_arg, Fdbus_method_return_internal):
19594 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19595 arguments, check that Lisp number is nonnegative, rather than
19596 silently wrapping negative numbers around. (Bug#8722)
19597 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19600 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19602 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19604 ccl: Add integer overflow checks.
19605 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19606 (IN_INT_RANGE): New macros.
19607 (ccl_driver): Use them to check for integer overflow when
19608 decoding a CCL program. Many of the new checks are whether XINT (x)
19609 fits in int; it doesn't always, on 64-bit hosts. The new version
19610 doesn't catch all possible integer overflows, but it's an
19611 improvement. (Bug#8719)
19613 * alloc.c (make_event_array): Use XINT, not XUINT.
19614 There's no need for unsigned here.
19616 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19617 This follows up to the 2011-05-06 change that substituted uintptr_t
19618 for EMACS_INT. This case wasn't caught back then.
19620 Rework Fformat to avoid integer overflow issues.
19621 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19622 now (part of C89). Include <verify.h>.
19623 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19624 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19625 (Fformat): Avoid the prepass trying to compute sizes; it was only
19626 approximate and thus did not catch overflow reliably. Instead, walk
19627 through the format just once, formatting and computing sizes as we go,
19628 checking for integer overflow at every step, and allocating a larger
19629 buffer as needed. Keep track separately whether the format is
19630 multibyte. Keep only the most-recently calculated precision, rather
19631 than them all. Record whether each argument has been converted to
19632 string. Use EMACS_INT, not int, for byte and char and arg counts.
19633 Support field widths and precisions larger than INT_MAX. Avoid
19634 sprintf's undefined behavior with conversion specifications such as %#d
19635 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19636 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19637 formatting out-of-range floating point numbers with int
19638 formats. (Bug#8668)
19640 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19642 * data.c: Avoid integer truncation in expressions involving floats.
19643 * data.c: Include <intprops.h>.
19644 (arith_driver): When there's an integer overflow in an expression
19645 involving floating point, convert the integers to floating point
19646 so that the resulting value does not suffer from catastrophic
19647 integer truncation. For example, on a 64-bit host (* 4
19648 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19649 Do not rely on undefined behavior after integer overflow.
19651 merge count_size_as_multibyte, parse_str_to_multibyte
19652 * character.c, character.h (count_size_as_multibyte):
19653 Rename from parse_str_to_multibyte; all uses changed.
19654 Check for integer overflow.
19655 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19656 since it's now a duplicate of the other. This is more of
19657 a character than a buffer op, so better that it's in character.c.
19658 * fns.c, print.c: Adjust to above changes.
19660 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19662 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19664 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19666 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19667 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19668 (x_clipboard_manager_save): Now static.
19669 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19671 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19672 (crypto_hash_function): Now static.
19673 Fix pointer signedness problems. Avoid unnecessary initializations.
19675 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19677 * termhooks.h (Vselection_alist): Make it terminal-local.
19679 * terminal.c (create_terminal): Initialize it.
19681 * xselect.c: Support for clipboard managers.
19682 (Vselection_alist): Move to termhooks.h as terminal-local var.
19683 (LOCAL_SELECTION): New macro.
19684 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19685 (symbol_to_x_atom): Remove gratuitous arg.
19686 (x_handle_selection_request, lisp_data_to_selection_data)
19687 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19688 (x_own_selection, x_get_local_selection, x_convert_selection):
19689 New arg, specifying work frame. Use terminal-local Vselection_alist.
19690 (some_frame_on_display): Delete unused function.
19691 (Fx_own_selection_internal, Fx_get_selection_internal)
19692 (Fx_disown_selection_internal, Fx_selection_owner_p)
19693 (Fx_selection_exists_p): New optional frame arg.
19694 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19695 (x_handle_selection_clear): Don't treat other terminals with the
19696 same keyboard specially. Use the terminal-local Vselection_alist.
19697 (x_clear_frame_selections): Use Frun_hook_with_args.
19699 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19701 * xterm.h: Add support for those atoms.
19703 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19705 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19706 (converted_selections, conversion_fail_tag): New global variables.
19707 (x_selection_request_lisp_error): Free the above.
19708 (x_get_local_selection): Remove unnecessary code.
19709 (x_reply_selection_request): Args changed; handle arbitrary array
19710 of converted selections stored in converted_selections.
19711 Separate the XChangeProperty and SelectionNotify steps.
19712 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19713 (x_convert_selection): New function.
19714 (x_handle_selection_event): Simplify.
19715 (x_get_foreign_selection): Don't ignore incoming requests while
19716 waiting for an answer; this will fail when we implement
19717 SAVE_TARGETS, and seems unnecessary anyway.
19718 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19719 (Vx_sent_selection_functions): Doc fix.
19721 2011-05-26 Leo Liu <sdl.web@gmail.com>
19723 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19725 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19727 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19729 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19730 for fringe update if it has periodic bitmap.
19731 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19732 and fringe_bitmap_periodic_p.
19734 * fringe.c (get_fringe_bitmap_data): New function.
19735 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19736 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19737 row. Mark glyph row for fringe update if periodicity changed.
19739 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19740 for fringe update unless it has periodic bitmap.
19742 2011-05-25 Kenichi Handa <handa@m17n.org>
19744 * xdisp.c (get_next_display_element): Set correct it->face_id for
19745 a static composition.
19747 2011-05-24 Leo Liu <sdl.web@gmail.com>
19750 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19752 * fns.c (crypto_hash_function, Fsha1): New function.
19753 (Fmd5): Use crypto_hash_function.
19754 (syms_of_fns): Add Ssha1.
19756 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19758 * gnutls.c: Remove unused macros.
19759 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19760 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19761 Remove macros that are defined and never used.
19762 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19764 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19766 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19767 (Fx_get_selection_internal): Minor cleanup.
19768 (Fx_own_selection_internal): Rename arguments for consistency with
19771 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19773 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19775 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19777 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19779 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19781 * dispnew.c (scrolling_window): Don't exclude the case that the
19782 last enabled row in the desired matrix touches the bottom boundary.
19784 2011-05-21 Glenn Morris <rgm@gnu.org>
19786 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19787 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19788 and add some more files.
19790 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19792 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19793 report_file_error introduced by the change from 2011-05-07.
19795 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19797 * systime.h (Time): Define only if emacs is defined.
19798 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19799 where the include path doesn't have X11/X.h by default. See
19800 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19802 2011-05-20 Kenichi Handa <handa@m17n.org>
19804 * composite.c (find_automatic_composition): Fix previous change.
19806 2011-05-20 Glenn Morris <rgm@gnu.org>
19808 * lisp.mk: New file, split from Makefile.in.
19809 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19810 (shortlisp): Remove.
19811 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19813 2011-05-19 Glenn Morris <rgm@gnu.org>
19815 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19816 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19817 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19818 (lisp): Set the order to that of loadup.el.
19819 (shortlisp): Make it a copy of $lisp.
19820 (SOME_MACHINE_LISP): Remove.
19821 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19822 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19824 2011-05-18 Kenichi Handa <handa@m17n.org>
19826 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19827 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19828 (find_automatic_composition): Mostly rewrite for efficiency.
19830 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19832 * makefile.w32-in: Update dependencies.
19834 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19836 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19837 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19839 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19841 Fix some integer overflow issues, such as string length overflow.
19843 * insdel.c (count_size_as_multibyte): Check for string overflow.
19845 * character.c (lisp_string_width): Check for string overflow.
19846 Use EMACS_INT, not int, for string indexes and lengths; in
19847 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19848 the resulting string length overflows an EMACS_INT; instead,
19849 report a string overflow if no precision given. When checking for
19850 precision exhaustion, use a check that cannot possibly have
19851 integer overflow. (Bug#8675)
19852 * character.h (lisp_string_width): Adjust to new signature.
19854 * alloc.c (string_overflow): New function.
19855 (Fmake_string): Use it. This doesn't change behavior, but saves
19856 a few bytes and will simplify future changes.
19857 * character.c (string_escape_byte8): Likewise.
19858 * lisp.h (string_overflow): New decl.
19860 Fixups, following up to the user-interface timestamp change.
19861 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19862 for UI timestamps, instead of unsigned long.
19863 * msdos.c (mouse_get_pos): Likewise.
19864 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19865 * w32gui.h (Time): Define by including "systime.h" rather than by
19866 declaring it ourselves. (Bug#8664)
19868 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19869 * image.c (clear_image_cache): Likewise.
19871 * term.c (term_mouse_position): Don't assume time_t wraparound.
19873 Be more systematic about user-interface timestamps.
19874 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19875 and sometimes 'EMACS_UINT', to represent these timestamps.
19876 This change causes it to use 'Time' uniformly, as that's what X uses.
19877 This makes the code easier to follow, and makes it easier to catch
19878 integer overflow bugs such as Bug#8664.
19879 * frame.c (Fmouse_position, Fmouse_pixel_position):
19880 Use Time, not unsigned long, for user-interface timestamps.
19881 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19882 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19883 * keyboard.h (last_event_timestamp): Likewise.
19884 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19885 * menu.h (xmenu_show): Likewise.
19886 * term.c (term_mouse_position): Likewise.
19887 * termhooks.h (struct input_event.timestamp): Likewise.
19888 (struct terminal.mouse_position_hook): Likewise.
19889 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19890 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19891 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19892 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19893 what it was before.
19894 * menu.h, termhooks.h: Include "systime.h", for Time.
19896 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19897 Don't assume that the difference between two unsigned long values
19898 can fit into an integer. At this point, we know button_down_time
19899 <= event->timestamp, so the difference must be nonnegative, so
19900 there's no need to cast the result if double-click-time is
19901 nonnegative, as it should be; check that it's nonnegative, just in
19902 case. This bug is triggered when events are more than 2**31 ms
19903 apart (about 25 days). (Bug#8664)
19905 * xselect.c (last_event_timestamp): Remove duplicate decl.
19906 (x_own_selection): Remove needless cast to unsigned long.
19908 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19909 that always fit in int. Use a sentinel instead of a counter, to
19910 avoid a temp and to allay GCC's concerns about possible int overflow.
19911 * frame.h (struct frame): Use int for menu_bar_items_used
19912 instead of EMACS_INT, since it always fits in int.
19914 * menu.c (grow_menu_items): Check for int overflow.
19916 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19918 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19919 Before, the code was not consistent. These values cannot exceed
19920 2**31 - 1 so there's no need to make them unsigned.
19921 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19922 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19923 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19925 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19927 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19928 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19929 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19930 presumably because the widths might not match.
19932 * window.c (size_window): Avoid needless test at loop start.
19934 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19936 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19938 2011-05-12 Drew Adams <drew.adams@oracle.com>
19940 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19942 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19944 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19945 `width' to `bar_area_x' and `bar_area_width', respectively.
19946 (x_scroll_run): Take account of fringe background extension.
19948 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19949 Rename local vars `left' and `width' to `bar_area_x' and
19950 `bar_area_width', respectively.
19951 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19952 background extension.
19954 2011-05-10 Jim Meyering <meyering@redhat.com>
19956 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19958 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19960 * image.c (Finit_image_library): Return t for built-in image types,
19961 like pbm and xbm. (Bug#8640)
19963 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19965 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19967 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19969 * w32console.c (Fset_screen_color): Doc fix.
19970 (Fget_screen_color): New function.
19971 (syms_of_ntterm): Defsubr it.
19973 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19974 unlink the temporary file if Fcall_process didn't create it in the
19976 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19977 child process will be redirected to a file specified with `:file'.
19978 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19979 cue to call_process_cleanup not to close that handle.
19981 2011-05-07 Ben Key <bkey76@gmail.com>
19983 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19984 one of two shell specific rules, either bootstrap-temacs-CMD or
19985 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19986 to the previous implementation of the bootstrap-temacs rule.
19987 The bootstrap-temacs-CMD rule is similar to the previous
19988 implementation of the bootstrap-temacs rule except that it
19989 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19992 These changes, along with some changes to nt/configure.bat,
19993 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19994 earlier fix to add support for --cflags and --ldflags options
19995 that include quotes so that it works whether make uses cmd or
19998 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20000 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20001 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20003 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20004 a string. Handle both cases.
20005 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20006 (Fdbus_register_method): Use Qinvalid_function.
20008 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20010 * makefile.w32-in: Update dependencies.
20011 (LISP_H): Add inttypes.h and stdin.h.
20012 (PROCESS_H): Add unistd.h.
20014 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20016 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20017 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20019 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20021 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20023 * term.c (vfatal): Remove stray call to va_end.
20024 It's not needed and the C Standard doesn't allow it here anyway.
20026 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20027 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20029 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20032 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20034 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20036 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20038 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20040 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20042 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20043 * charset.c (Fdefine_charset_internal): Don't initialize
20044 charset.code_space[15]. The value was garbage, on hosts with
20045 32-bit int (Bug#8600).
20047 * lread.c (read_integer): Be more consistent with string-to-number.
20048 Use string_to_number to do the actual conversion; this avoids
20049 rounding errors and fixes some other screwups. Without this fix,
20050 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20051 (digit_to_number): Move earlier, for benefit of read_integer.
20052 Return -1 if the digit is out of range for the base, -2 if it is
20053 not a digit in any supported base. (Bug#8602)
20055 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20057 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20058 to match comment at start of function. This also removes a
20059 GCC warning about overflow in a 32+64-bit port.
20061 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20063 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20064 Reported by Stefan Monnier in
20065 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20066 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20067 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20069 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20070 (EMACS_UINTPTR): Likewise, with uintptr_t.
20072 * lisp.h: Prefer 64-bit EMACS_INT if available.
20073 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20074 on 32-bit hosts that have 64-bit int, so that they can access
20076 However, temporarily disable this change unless the temporary
20077 symbol WIDE_EMACS_INT is defined.
20079 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20081 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20082 This removes an assumption that EMACS_INT and long are the same
20083 width as pointers. The assumption is true for Emacs porting targets
20084 now, but we want to make other targets possible.
20085 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20086 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20087 In the rest of the code, change types of integers that hold casted
20088 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20089 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20090 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20091 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20092 No need to cast type when ORing.
20093 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20094 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20095 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20096 assume EMACS_INT is the same width as char *.
20097 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20098 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20099 Remove no-longer-needed casts.
20100 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20101 (xg_tool_bar_help_callback, xg_make_tool_item):
20102 Use EMACS_INTPTR to hold an integer
20103 that will be cast to void *; this can avoid a GCC warning
20104 if EMACS_INT is not the same width as void *.
20105 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20106 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20107 (current_message_1, set_message_1):
20108 Use a local to convert to proper width without a cast.
20109 * xmenu.c (dialog_selection_callback): Likewise.
20111 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20112 Also, don't assume VALBITS / RAND_BITS is less than 5,
20113 and don't rely on undefined behavior when shifting a 1 left into
20115 * lisp.h (get_random): Change signature to match.
20117 * lread.c (hash_string): Use size_t, not int, for hash computation.
20118 Normally we prefer signed values; but hashing is special, because
20119 it's better to use unsigned division on hash table sizes so that
20120 the remainder is nonnegative. Also, size_t is the natural width
20121 for hashing into memory. The previous code used 'int', which doesn't
20122 retain enough info to hash well into very large tables.
20123 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20125 * dbusbind.c: Don't possibly lose pointer info when converting.
20126 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20127 Use XPNTR rather than XHASH, so that the high-order bits of
20128 the pointer aren't lost when converting through void *.
20130 * eval.c (Fautoload): Don't double-shift a pointer.
20132 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20134 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20136 * gnutls.c (DEF_GNUTLS_FN):
20137 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20139 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20141 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20144 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20146 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20147 New version that can reserve upto 2GB of heap space.
20149 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20151 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20153 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20155 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20156 `gnutls_certificate_set_x509_key_file'.
20158 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20160 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20161 Update dependencies.
20163 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20165 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20166 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20167 Remove unused parameter `fildes'.
20168 * process.c (read_process_output, send_process): Don't pass it.
20170 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20172 Fix previous change: the library cache is defined in w32.c.
20173 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20174 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20176 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20178 Implement dynamic loading of GnuTLS on Windows.
20180 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20181 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20182 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20185 * gnutls.c (Qgnutls_dll): Define.
20186 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
20187 (gnutls_*): Declare function pointers.
20188 (init_gnutls_functions): New function to initialize function pointers.
20189 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
20190 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
20191 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20192 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
20193 (emacs_gnutls_write, emacs_gnutls_read)
20194 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20195 (Fgnutls_available_p): New function.
20196 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
20197 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
20198 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
20200 * image.c: Include w32.h.
20201 (Vimage_type_cache): Delete.
20202 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
20203 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
20204 (w32_delayed_load): Move to w32.c.
20206 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20208 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20209 (w32_delayed_load): Move from image.c. When loading a library, record
20210 its filename in the :loaded-from property of the library id.
20211 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20212 Initialize and staticpro them.
20213 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20215 * process.c: Include lisp.h before w32.h, not after.
20216 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20217 instead of gnutls_record_check_pending.
20219 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20221 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20223 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20224 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20227 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20229 * xterm.c (x_set_frame_alpha): Do not set property on anything
20230 else than FRAME_X_OUTER_WINDOW (Bug#8608).
20232 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20234 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
20236 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20238 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

20245 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
20246 (Qgnutls_bootprop_callbacks_verify): Make static.
20248 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
20250 * callproc.c: Indentation fixup.
20252 * sysdep.c (wait_for_termination_1): Make static.
20253 (wait_for_termination, interruptible_wait_for_termination):
20254 Move after wait_for_termination_1.
20256 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
20258 * sysdep.c (interruptible_wait_for_termination): New function
20259 which is like wait_for_termination, but allows keyboard
20262 * callproc.c (Fcall_process): Add (:file "file") as an option for
20264 (Fcall_process_region): Ditto.
20266 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20268 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20269 rather than `XVECTOR (FOO)->size'.
20271 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20272 inttypes.h, as a gnulib replacement is used if it not available in
20275 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20277 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20278 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20279 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20281 * coding.c (coding_alloc_by_realloc): Error out if destination
20282 will grow beyond MOST_POSITIVE_FIXNUM.
20283 (decode_coding_emacs_mule): Abort if there isn't enough place in
20284 charbuf for the composition carryover bytes. Reserve an extra
20285 space for up to 2 characters produced in a loop.
20286 (decode_coding_iso_2022): Abort if there isn't enough place in
20287 charbuf for the composition carryover bytes.
20289 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20291 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
20292 aborting when %lld or %lll format is passed.
20293 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20294 %llo or %llx format is passed. (Bug#8545)
20296 * window.c (window_scroll_line_based): Use a marker instead of
20297 simple variables to record original value of point. (Bug#7952)
20299 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20300 produced by %s or %c overflows available buffer space. (Bug#8545)
20302 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20304 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20305 (SIZE_MAX): Move defn after all includes, as they might #define it.
20307 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20309 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20311 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20313 * keyboard.c (Qdelayed_warnings_hook): Define.
20314 (command_loop_1): Run `delayed-warnings-hook'
20315 if Vdelayed_warnings_list is non-nil.
20316 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20317 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20319 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20321 * doprnt.c (doprnt): Don't return value smaller than the buffer
20322 size if the message was truncated. (Bug#8545).
20324 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20326 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20327 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20329 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20331 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20333 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20335 * makefile.w32-in: Update dependencies.
20337 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20339 Improve `doprnt' and its usage. (Bug#8545)
20340 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20341 `format_end'. Remove support for %l as a conversion specifier.
20342 Don't use xrealloc. Improve diagnostics when the %l size modifier
20343 is used. Update the commentary.
20345 * eval.c (verror): Simplify calculation of size_t.
20347 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20350 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20352 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20355 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20357 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20358 This makes this file independent of the recent pseudovector change.
20360 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20362 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20364 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20365 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20366 Remove unused local.
20367 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20369 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20370 GCC 4.6.0 optimizes based on type-based alias analysis.
20371 For example, if b is of type struct buffer * and v of type struct
20372 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20373 != &v->size, and therefore "v->size = 1; b->size = 2; return
20374 v->size;" must therefore return 1. This assumption is incorrect
20375 for Emacs, since it type-puns struct Lisp_Vector * with many other
20376 types. To fix this problem, this patch adds a new type struct
20377 vectorlike_header that documents the constraints on layout of vectors
20378 and pseudovectors, and helps optimizing compilers not get fooled
20379 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20380 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20381 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20383 (XSETPVECTYPE): Rewrite in terms of new macro.
20384 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20385 This is a bit clearer, and further avoids the possibility of
20386 undesirable aliasing.
20387 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20388 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20389 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20390 since Lisp_Subr is a special case (no "next" field).
20391 (ASIZE): Now uses header.size rather than size.
20392 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20393 to avoid the hassle of writing XVECTOR (foo)->header.size.
20394 (struct vectorlike_header): New type.
20395 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20396 object, to help avoid aliasing.
20397 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20398 (SUBRP): Likewise, since Lisp_Subr is a special case.
20399 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20400 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20401 (struct Lisp_Hash_Table): Combine first two members into a single
20402 struct vectorlike_header member. All uses of "size" and "next" members
20403 changed to be "header.size" and "header.next".
20404 * buffer.h (struct buffer): Likewise.
20405 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20406 * frame.h (struct frame): Likewise.
20407 * process.h (struct Lisp_Process): Likewise.
20408 * termhooks.h (struct terminal): Likewise.
20409 * window.c (struct save_window_data, struct saved_window): Likewise.
20410 * window.h (struct window): Likewise.
20411 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20412 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20413 * buffer.c (init_buffer_once): Likewise.
20414 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20416 * process.c (Fformat_network_address): Use local var for size,
20419 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20421 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20422 * data.c (atof): Remove decl; no longer used or needed.
20423 (digit_to_number): Move to lread.c.
20424 (Fstring_to_number): Use new string_to_number function, to be
20425 consistent with how the Lisp reader treats infinities and NaNs.
20426 Do not assume that floating-point numbers represent EMACS_INT
20427 without losing information; this is not true on most 64-bit hosts.
20428 Avoid double-rounding errors, by insisting on integers when
20429 parsing non-base-10 numbers, as the documentation specifies.
20430 * lisp.h (string_to_number): New decl, replacing ...
20431 (isfloat_string): Remove.
20432 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20433 (read1): Do not accept +. and -. as integers; this
20434 appears to have been a coding error. Similarly, do not accept
20435 strings like +-1e0 as floating point numbers. Do not report
20436 overflow for integer overflows unless the base is not 10 which
20437 means we have no simple and reliable way to continue.
20438 Break out the floating-point parsing into a new
20439 function string_to_number, so that Fstring_to_number parses
20440 floating point numbers consistently with the Lisp reader.
20441 (digit_to_number): Move here from data.c. Make it static inline.
20442 (E_CHAR, EXP_INT): Remove, replacing with ...
20443 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20444 (string_to_number): New function, replacing isfloat_string.
20445 This function checks for valid syntax and produces the resulting
20446 Lisp float number too. Rework it so that string-to-number
20447 no longer mishandles examples like "1.0e+". Use strtoumax,
20448 so that overflow for non-base-10 numbers is reported only when
20449 there's no portable and simple way to convert to floating point.
20451 * textprop.c (set_text_properties_1): Rewrite for clarity,
20452 and to avoid GCC warning about integer overflow.
20454 * intervals.h (struct interval): Use EMACS_INT for members
20455 where EMACS_UINT might cause problems. See
20456 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20457 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20458 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20460 (offset_intervals): Tell GCC not to worry about length overflow
20461 when negating a negative length.
20463 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20464 (overrun_check_free): Likewise.
20466 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20467 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20470 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20471 (gnutls_make_error): Rename local to avoid shadowing.
20472 (gnutls_emacs_global_deinit): ifdef out; not used.
20473 (Fgnutls_boot): Use const for pointer to readonly storage.
20474 Comment out unused local. Fix pointer signedness problems.
20476 * lread.c (openp): Don't stuff size_t into an 'int'.
20477 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20478 about possible signed overflow.
20480 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20481 (GDK_KEY_g): Don't define if already defined.
20482 (xg_prepare_tooltip): Avoid pointer signedness problem.
20483 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20485 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20486 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20488 * xfns.c (Fx_window_property): Simplify a bit,
20489 to make a bit faster and to avoid GCC 4.6.0 warning.
20490 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20492 * fns.c (internal_equal): Don't assume size_t fits in int.
20494 * alloc.c (compact_small_strings): Tighten assertion a little.
20496 Replace pEd with more-general pI, and fix some printf arg casts.
20497 * lisp.h (pI): New macro, generalizing old pEd macro to other
20498 conversion specifiers. For example, use "...%"pI"d..." rather
20499 than "...%"pEd"...".
20500 (pEd): Remove. All uses replaced with similar uses of pI.
20501 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20502 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20503 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20504 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20505 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20506 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20507 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20509 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20510 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20511 * print.c (safe_debug_print, print_object): Likewise.
20512 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20514 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20515 avoiding the 0 flag, which is not portable.
20516 * process.c (Fmake_network_process): Use pI to avoid cast.
20517 * region-cache.c (pp_cache): Likewise.
20518 * xdisp.c (decode_mode_spec): Likewise.
20519 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20520 behavior on 64-bit hosts with printf arg.
20521 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20522 (x_stop_queuing_selection_requests): Likewise.
20523 (x_get_window_property): Don't truncate byte count to an 'int'
20526 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20527 here, since it parses constructs like leading '-' and spaces,
20528 which are not wanted; and it overflows with large numbers.
20529 Instead, simply match F[0-9]+, which is what is wanted anyway.
20531 * alloc.c: Remove unportable assumptions about struct layout.
20532 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20533 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20534 (allocate_vectorlike, make_pure_vector): Use the new macros,
20535 plus offsetof, to remove unportable assumptions about struct layout.
20536 These assumptions hold on all porting targets that I know of, but
20537 they are not guaranteed, they're easy to remove, and removing them
20538 makes further changes easier.
20540 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20541 This doesn't fix a bug but makes the code clearer.
20542 (string_overrun_cookie): Now const. Use initializers that
20543 don't formally overflow signed char, to avoid warnings.
20544 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20545 can cause Emacs to crash when string overrun checking is enabled.
20546 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20547 multiple of sizeof (EMACS_INT); it need not be, if
20548 alignof(EMACS_INT) < sizeof (EMACS_INT).
20549 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20551 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

20558 supposed to be handshaking. (Bug#8556)
20559 Reported by Paul Eggert <eggert@cs.ucla.edu>.
20561 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

20578 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20580 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20581 "cast to pointer from integer of different size".
20583 Improve doprnt and its use in verror. (Bug#8545)
20584 * doprnt.c (doprnt): Document the set of format control sequences
20585 supported by the function. Use SAFE_ALLOCA instead of always
20588 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20589 is one byte too soon. Don't use xrealloc; instead xfree and
20592 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20594 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20597 * gnutls.c: Renamed global_initialized to
20598 gnutls_global_initialized. Added internals for the
20599 :verify-hostname-error, :verify-error, and :verify-flags
20600 parameters of `gnutls-boot' and documented those parameters in the
20601 docstring. Start callback support.
20602 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20603 unless a fatal error occurred. Call gnutls_alert_send_appropriate
20604 on error. Return error code.

20664 changes in globals.h immediately force recompilation.
20665 (TAGS): Depend on $(CURDIR)/m/intel386.h and
20666 $(CURDIR)/s/ms-w32.h.

20676 * doprnt.c: Include limits.h.
20677 (SIZE_MAX): New macro.
20678 (doprnt): Return a size_t value. 2nd arg is now size_t.
20679 Many local variables are now size_t instead of int or unsigned.
20680 Improve overflow protection. Support `l' modifier for integer
20681 conversions. Support %l conversion. Don't assume an EMACS_INT
20682 argument for integer conversions and for %c.
20684 * lisp.h (doprnt): Restore prototype.
20686 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
20687 $(SRC)/character.h.
20689 * Makefile.in (base_obj): Add back doprnt.o.
20691 * deps.mk (doprnt.o): Add back prerequisites.
20692 (callint.o): Depend on character.h.
20694 * eval.c (internal_lisp_condition_case): Include the handler
20695 representation in the error message.

20701 * callint.c (Fcall_interactively): When displaying error message
20702 about invalid control letter, pass the character's codepoint, not
20703 a pointer to its multibyte form. Improve display of the character
20704 in octal and display also its hex code.
20706 * character.c (char_string): Use %x to display the (unsigned)
20707 codepoint of an invalid character, to avoid displaying a bogus
20710 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
20711 `error', not SYMBOL_NAME itself.
20713 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
20714 character arguments to `error'.
20716 * charset.c (check_iso_charset_parameter): Fix incorrect argument
20717 to `error' in error message about FINAL_CHAR argument. Make sure
20718 FINAL_CHAR is a character, and use %c when it is passed as

20783 Define only if needed.
20785 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
20786 by pacifying GCC about it. Maybe it's time to retire it?
20787 * xfaces.c (USG, __TIMEVAL__): Likewise.
20789 * dispextern.h (struct redisplay_interface): Rename param
20790 to avoid shadowing.
20791 * termhooks.h (struct terminal): Likewise.
20792 * xterm.c (xembed_send_message): Likewise.
20794 * insdel.c (make_gap_smaller): Define only if
20795 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
20797 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
20800 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
20801 so that we aren't warned about unused symbols.
20803 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
20805 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

20812 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
20813 (x_dispatch_event): Declare static if USE_GTK, and
20814 define if USE_GTK || USE_X_TOOLKIT.
20815 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
20816 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.

20818 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
20820 * xmenu.c (menu_help_callback): Pointer type fixes.
20821 Use const pointers when pointing at readonly data. Avoid pointer

20838 compatible char. Avoid the old compiler warnings about
20839 out-of-range initializers by using, for example, '\xab' rather
20842 * xgselect.c (xgselect_initialize): Check vs interface
20843 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

20912 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
20913 --enable-checking=xmallocoverrun). xfree is now used to
20914 deallocate these memory blocks.

21294 (n_float_blocks, float_free_list, cons_block, cons_block_index):
21295 (cons_free_list, last_marked_index):
21297 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
21298 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
21299 (mark_backtrace): Define only if BYTE_MARK_STACK.
21300 * xdisp.c (message_enable_multibyte): Now static.
21302 Declare Lisp_Object Q* variables to be 'static' if not exported.
21303 This makes it easier for human readers (and static analyzers)
21304 to see whether these variables are used from other modules.
21305 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
21306 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
21307 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
21308 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
21309 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
21310 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
21311 * xmenu.c, xselect.c:
21312 Declare Q* vars static if they are not used in other modules.
21313 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
21314 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
21315 Remove decls of unexported vars.
21316 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21318 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21320 Make Emacs functions such as Fatom 'static' by default.
21321 This makes it easier for human readers (and static analyzers)
21322 to see whether these functions can be called from other modules.
21323 DEFUN now defines a static function. To make the function external
21324 so that it can be used in other C modules, use the new macro DEFUE.
21325 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21326 (Finit_image_library):
21327 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21328 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21329 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21330 Remove decls, since these functions are now static.
21331 (Funintern, Fget_internal_run_time): New decls, since these functions
21332 were already external.
21334 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21335 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
21336 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:

21339 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
21340 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
21341 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21342 Mark functions with DEFUE instead of DEFUN,
21343 if they are used in other modules.
21344 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21345 decls for now-static functions.
21346 * buffer.h (Fdelete_overlay): Remove decl.
21347 * callproc.c (Fgetenv_internal): Mark as internal.
21348 * composite.c (Fremove_list_of_text_properties): Remove decl.

21352 * doc.c (Fdocumntation_property): New forward static decl.
21353 * eval.c (Ffetch_bytecode): New forward static decl.
21354 (Funintern): Remove extern decl; now in .h file where it belongs.
21355 * fileio.c (Fmake_symbolic_link): New forward static decl.
21356 * image.c (Finit_image_library): New forward static decl.
21357 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21358 * intervals.h (Fprevious_property_change):
21359 (Fremove_list_of_text_properties): Remove decls.
21360 * keyboard.c (Fthis_command_keys): Remove decl.
21361 (Fcommand_execute): New forward static decl.
21362 * keymap.c (Flookup_key): New forward static decl.
21363 (Fcopy_keymap): Now static.
21364 * keymap.h (Flookup_key): Remove decl.
21365 * process.c (Fget_process): New forward static decl.
21366 (Fprocess_datagram_address): Mark as internal.

21377 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
21379 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21382 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21384 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21385 when at ZV. (Bug#8487)
21387 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21389 * charset.c (Fclear_charset_maps): Use xfree instead of free.
21391 * keyboard.c (parse_tool_bar_item): Likewise.
21392 * sound.c (sound_cleanup, alsa_close): Likewise.
21393 * termcap.c (tgetent): Likewise.
21394 * xfns.c (x_default_font_parameter): Likewise.
21395 * xsettings.c (read_and_apply_settings): Likewise.
21397 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21398 (overrun_check_free): Protoize.
21400 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21402 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21403 since callers should never pass a negative size.
21404 Change the signature to match that of plain 'read' and 'write'; see
21405 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21406 * lisp.h: Update prototypes of emacs_write and emacs_read.
21408 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21410 * xdisp.c (redisplay_window): Don't try to determine the character
21411 position of the scroll margin if the window start point w->startp
21412 is outside the buffer's accessible region. (Bug#8468)
21414 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21416 Fix write-region and its subroutines for buffers > 2GB.
21417 * fileio.c (a_write, e_write): Modify declaration of arguments and
21418 local variables to support buffers larger than 2GB.
21419 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21421 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21422 argument, local variables, and return value.
21424 * lisp.h: Update prototypes of emacs_write and emacs_read.
21426 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21428 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21430 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21432 Fix more problems found by GCC 4.6.0's static checks.
21434 * xdisp.c (vmessage): Use a better test for character truncation.
21436 * charset.c (load_charset_map): <, not <=, for optimization,
21437 and to avoid potential problems with integer overflow.
21438 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21439 * casetab.c (set_identity, shuffle): Likewise.
21440 * editfns.c (Fformat): Likewise.
21441 * syntax.c (skip_chars): Likewise.
21443 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21444 This also lets GCC 4.6.0 generate slightly better loop code.
21446 * callint.c (Fcall_interactively): <, not <=, for optimization.
21447 (Fcall_interactively): Count the number of arguments produced,
21448 not the number of arguments given. This is simpler and lets GCC
21449 4.6.0 generate slightly better code.
21451 * ftfont.c: Distingish more carefully between FcChar8 and char.
21452 The previous code passed unsigned char * to a functions like
21453 strlen and xstrcasecmp that expect char *, which does not
21454 conform to the C standard.
21455 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21456 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21457 char * when the C standard requires it.
21459 * keyboard.c (read_char): Remove unused var.
21461 * eval.c: Port to Windows vsnprintf (Bug#8435).
21462 Include <limits.h>.
21463 (SIZE_MAX): Define if the headers do not.
21464 (verror): Do not give up if vsnprintf returns a negative count.
21465 Instead, grow the buffer. This ports to Windows vsnprintf, which
21466 does not conform to C99. Problem reported by Eli Zaretskii.
21467 Also, simplify the allocation scheme, by avoiding the need for
21468 calling realloc, and removing the ALLOCATED variable.
21470 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21472 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21473 But keep the doprint source code for now, as we might revamp it
21474 and use it again (Bug#8435).
21475 * lisp.h (doprnt): Remove.
21476 * Makefile.in (base_obj): Remove doprnt.o.
21477 * deps.mk (doprnt.o): Remove.
21479 error: Print 32- and 64-bit integers portably (Bug#8435).
21480 Without this change, on typical 64-bit hosts error ("...%d...", N)
21481 was used to print both 32- and 64-bit integers N, which relied on
21482 undefined behavior.
21483 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21484 * lisp.h (error, verror): Mark as printf-like functions.
21485 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21486 Report overflow in size calculations when allocating printf buffer.
21487 Do not truncate output string at its first null byte.
21488 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21489 Truncate the output at a character boundary, since vsnprintf does not
21491 * charset.c (check_iso_charset_parameter): Convert internal
21492 character to string before calling 'error', since %c now has the
21494 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21495 overflow when computing char to be passed to 'error'. Do not
21496 pass Lisp_Object to 'error'; pass the integer instead.
21497 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21498 formatted with plain %d.
21500 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21502 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21504 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21506 * xterm.c (x_catch_errors): Remove duplicate declaration.
21508 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21510 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21512 2011-04-10 Jim Meyering <meyering@redhat.com>
21514 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21515 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21516 return ssize_t not "int", and use size_t as the buffer length.
21517 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21518 * gnutls.h: Update declarations.
21519 * process.c (read_process_output): Use ssize_t, to match.
21520 (send_process): Likewise.
21522 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21524 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21526 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21528 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21529 Use unsigned char, to match FcChar8 type definition.
21531 * xterm.c (handle_one_xevent):
21532 * xmenu.c (create_and_show_popup_menu):
21533 * xselect.c (x_decline_selection_request)
21534 (x_reply_selection_request): Avoid type-punned deref of X events.
21536 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21538 Fix some uses of `int' instead of EMACS_INT.
21539 * search.c (string_match_1, fast_string_match)
21540 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21541 (scan_buffer, find_next_newline_no_quit)
21542 (find_before_next_newline, search_command, Freplace_match)
21543 (Fmatch_data): Make some `int' variables be EMACS_INT.
21545 * xdisp.c (display_count_lines): 3rd argument and return value now
21546 EMACS_INT. All callers changed.
21547 (pint2hrstr): Last argument is now EMACS_INT.
21549 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21550 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21551 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
21552 (decode_coding_utf_16, decode_coding_emacs_mule)
21553 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
21554 (decode_coding_ccl, decode_coding_charset)
21555 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
21556 (decode_coding_iso_2022, decode_coding_emacs_mule)
21557 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
21558 <char_offset, last_offset>: Declare EMACS_INT.
21559 (encode_coding_utf_8, encode_coding_utf_16)
21560 (encode_coding_emacs_mule, encode_invocation_designation)
21561 (encode_designation_at_bol, encode_coding_iso_2022)
21562 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21563 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21565 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21566 (encode_invocation_designation): Last argument P_NCHARS is now
21568 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21569 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21571 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21574 * ccl.c (Fccl_execute_on_string): Declare some variables
21577 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21579 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21581 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21583 * process.c (Fformat_network_address): Doc fix.
21585 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21587 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21589 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21591 * keyboard.c (read_char): Call Lisp function help-form-show,
21592 instead of using internal_with_output_to_temp_buffer.
21593 (Qhelp_form_show): New var.
21594 (syms_of_keyboard): Use DEFSYM macro.
21596 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21598 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21600 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21602 * process.c (Flist_processes): Remove to Lisp.
21603 (list_processes_1): Delete.
21605 2011-04-06 Eli Zaretskii <eliz@gnu.org>
21607 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21609 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21611 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21613 Fix more problems found by GCC 4.6.0's static checks.
21615 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
21617 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21619 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21621 * xdisp.c (vmessage): Mark as a printf-like function.
21623 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21625 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21627 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21628 printf-like functions.

21630 to system-supplied API.
21632 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21634 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21635 This avoids several warnings with gcc -Wstrict-overflow.
21636 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21637 directly, rather than having caller test rule sign. This avoids
21638 some unnecessary tests.
21639 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21640 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21641 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21643 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21644 (xfont_open): Avoid unnecessary tests.
21646 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21648 * composite.h, composite.c (composition_gstring_put_cache):
21649 Use EMACS_INT, not int, for length.
21651 * composite.h (COMPOSITION_DECODE_REFS): New macro,
21652 breaking out part of COMPOSITION_DECODE_RULE.
21653 (COMPOSITION_DECODE_RULE): Use it.
21654 * composite.c (get_composition_id): Remove unused local vars,
21655 by using the new macro.
21657 * textprop.c (set_text_properties_1): Change while to do-while,
21658 since the condition is always true at first.
21660 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21661 (interval_deletion_adjustment): Return unsigned value.
21664 * process.c (list_processes_1, create_pty, read_process_output):
21665 (exec_sentinel): Remove vars that were set but not used.
21666 (create_pty): Remove unnecessary "volatile"s.
21667 (Fnetwork_interface_info): Avoid possibility of int overflow.

21669 (read_process_output): Simplify nbytes computation if buffered.
21671 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
21673 * syntax.c (scan_words): Remove var that was set but not used.
21674 (update_syntax_table): Use unsigned instead of int.
21676 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21677 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21678 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21680 * print.c (print_error_message): Avoid int overflow.
21682 * font.c (font_list_entities): Redo for clarity,
21683 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21685 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21686 (font_score): Avoid potential overflow in diff calculation.
21688 * fns.c (substring_both): Remove var that is set but not used.
21689 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21691 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21693 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21694 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21695 can always succeed if overflow has undefined behavior.
21697 * search.c (boyer_moore, wordify): Remove vars set but not used.
21698 (wordify): Omit three unnecessary tests.
21700 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21701 All callers changed. This avoids the need for an unused var.
21703 * casefiddle.c (casify_region): Remove var that is set but not used.
21705 * dired.c (file_name_completion): Remove var that is set but not used.
21707 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21709 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21710 (Finsert_file_contents): Remove unnecessary code checking fd.
21712 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21713 Check for integer overflow on size calculations.
21715 * buffer.c (Fprevious_overlay_change): Remove var that is set
21718 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21719 Remove vars that are set but not used.
21720 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21721 (timer_check_2): Mark vars as initialized.
21723 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21725 * image.c (lookup_image): Remove var that is set but not used.
21726 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21728 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21729 that are set but not used.
21731 * xfns.c (make_invisible_cursor): Don't return garbage
21732 if XCreateBitmapFromData fails (Bug#8410).
21734 * xselect.c (x_get_local_selection, x_handle_property_notify):
21735 Remove vars that are set but not used.
21737 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

21741 Remove var that is set but not used.
21742 (scroll_bar_windows_size): Now size_t, not int.
21743 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21744 Check for overflow.
21746 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21747 (map_tty_color) [!defined MSDOS]: Likewise.
21749 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21751 * coding.c: Remove vars that are set but not used.
21752 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

21759 that is set but not used.
21761 * print.c (print_object): Remove var that is set but not used.
21763 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21764 The gnulib version avoids calling malloc in the usual case,
21765 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21766 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21767 * filelock.c (current_lock_owner): Likewise.
21768 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21769 * sysdep.c: Include allocator.h, careadlinkat.h.
21770 (emacs_no_realloc_allocator): New static constant.
21771 (emacs_readlink): New function.
21772 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21773 ../lib/careadlinkat.h.
21775 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21777 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

21799 do not dereference NULL upon failed strdup
21800 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21801 (ns_get_family): Likewise.
21803 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21805 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21807 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21809 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21812 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21814 Add lexical binding.
21816 * window.c (Ftemp_output_buffer_show): New fun.

21825 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21827 (syms_of_lread): Declare `lexical-binding'.
21829 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21831 * keyboard.c (eval_dyn): New fun.
21832 (menu_item_eval_property): Use it.
21834 * image.c (parse_image_spec): Use Ffunctionp.
21836 * fns.c (concat, mapcar1): Accept byte-code-functions.
21838 * eval.c (Fsetq): Handle lexical vars.
21839 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21840 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21841 (FletX, Flet): Obey lexical binding.
21842 (Fcommandp): Handle closures.
21843 (Feval): New `lexical' arg.
21844 (eval_sub): New function extracted from Feval. Use it almost
21845 everywhere where Feval was used. Look up vars in lexical env.
21847 (Ffunctionp): Move from subr.el.
21848 (Ffuncall): Handle closures.
21849 (apply_lambda): Remove `eval_flags'.
21850 (funcall_lambda): Handle closures and new byte-code-functions.
21851 (Fspecial_variable_p): New function.
21852 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21853 but without exporting it to Lisp.
21855 * doc.c (Fdocumentation, store_function_docstring):
21856 * data.c (Finteractive_form): Handle closures.
21858 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21861 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21863 (exec_byte_code): New function extracted from Fbyte_code to handle new
21864 calling convention for byte-code-functions. Add new byte-codes.
21866 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21868 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21870 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21872 * xdisp.c (redisplay_internal): Fix prototype.
21874 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21876 * xdisp.c (SCROLL_LIMIT): New macro.
21877 (try_scrolling): Use it when setting scroll_limit.
21878 Limit scrolling to 100 screen lines.
21879 (redisplay_window): Even when falling back on "recentering",
21880 position point in the window according to scroll-conservatively,
21881 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21883 (try_scrolling): When point is above the window, allow searching
21884 as far as scroll_max, or one screenful, to compute vertical
21885 distance from PT to the scroll margin position. This prevents
21886 try_scrolling from unnecessarily failing when
21887 scroll-conservatively is set to a value slightly larger than the
21888 window height. Clean up the case of PT below the margin at bottom
21889 of window: scroll_max can no longer be INT_MAX. When aggressive
21890 scrolling is in use, don't let point enter the opposite scroll
21891 margin as result of the scroll.
21892 (syms_of_xdisp) <scroll-conservatively>: Document the
21893 threshold of 100 lines for never-recentering scrolling.

21900 (message_log_check_duplicate): Remove parameters `prev_bol' and
21901 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21902 (redisplay_internal): Remove parameter `preserve_echo_area',
21903 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21905 * indent.c (Fvertical_motion):
21906 * window.c (window_scroll_pixel_based, Frecenter):
21907 Don't pass `need_y_p' to `move_it_by_lines'.
21909 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21911 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21912 steal a few bits to be more compact.
21913 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21914 Remove unneeded casts.
21916 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21918 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21920 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21921 binding" message (bug#7967).
21923 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21925 Fix more problems found by GCC 4.6.0's static checks.
21927 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21928 Remove unused local var.
21930 * editfns.c (Fmessage_box): Remove unused local var.
21932 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21933 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21934 Omit unused local vars.
21935 * window.c (shrink_windows): Omit unused local var.
21936 * menu.c (digest_single_submenu): Omit unused local var.
21937 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21938 Omit unused local var.
21940 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21941 Don't assume string length fits in int.
21942 (keyremap_step, read_key_sequence): Use size_t for sizes.

21946 instead of alloca (Bug#8344).
21948 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21949 (Fbacktrace_frame): Don't assume nframes fits in int.
21951 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

21958 * cm.c (calccost): Turn while-do into do-while, for clarity.
21960 * keyboard.c (syms_of_keyboard): Use the same style as later
21961 in this function when indexing through an array. This also
21962 works around GCC bug 48267.
21964 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21966 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21968 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21969 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21971 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21972 This avoids undefined behavior on integer overflow, and is a bit
21973 more convenient anyway since it is compared to a size_t variable.
21975 Variadic C functions now count arguments with size_t, not int.
21976 This avoids an unnecessary limitation on 64-bit machines, which
21977 caused (substring ...) to crash on large vectors (Bug#8344).

21987 * fns.c (concat): Likewise.
21988 * frame.c (x_set_frame_parameters): Likewise.
21989 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21990 0 if not found, not -1. All callers changed.
21992 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21993 (stack_copy_size): Now size_t, not int.
21994 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21996 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21998 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
21999 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

22015 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22016 don't set the hook to nil, but remove the offending function instead.
22017 (Qcommand_hook_internal): Remove, unused.
22018 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22019 Vcommand_hook_internal.

22022 (funcall_nil, funcall_not): New functions.
22023 (run_hook_with_args): Call each function through a `funcall' argument.

22167 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
22168 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
22169 (Fx_close_connection): Remove unused variable `i'.
22171 * w32font.c (w32font_draw): Return number of glyphs.
22172 (w32font_open_internal): Remove unused variable `i'.
22173 (w32font_driver): Add missing initializer.
22175 * w32menu.c (utf8to16): Remove unused variable `utf16'.

22187 2011-03-23 Julien Danjou <julien@danjou.info>
22189 * term.c (Fsuspend_tty, Fresume_tty):
22190 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22191 * window.c (temp_output_buffer_show):
22192 * insdel.c (signal_before_change):
22193 * frame.c (Fhandle_switch_frame):
22194 * fileio.c (Fdo_auto_save):

22197 * cmds.c (internal_self_insert):
22198 * callint.c (Fcall_interactively):
22199 * buffer.c (Fkill_all_local_variables):
22200 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22202 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22203 unconditionally since it does the check itself.
22205 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22207 Fix more problems found by GCC 4.5.2's static checks.
22209 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22210 the first time through the loop, since we know p0 < p1 then.
22211 This also avoids a gcc -Wstrict-overflow warning.
22213 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22214 leading to a memory leak, possible in functions like
22215 load_charset_map_from_file that can allocate an unbounded number
22216 of objects (Bug#8318).
22218 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22219 that could (at least in theory) be that large.
22221 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22222 This is less likely to overflow, and avoids undefined behavior if
22223 overflow does occur. All callers changed. Use strtoul to scan
22224 for the unsigned long integer.
22225 (pint2hrstr): Simplify and tune code slightly.
22226 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22228 * scroll.c (do_scrolling): Work around GCC bug 48228.
22229 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
22231 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
22232 This also avoids a warning with gcc -Wstrict-overflow.
22233 (validate_x_resource_name): Simplify count usage.
22234 This also avoids a warning with gcc -Wstrict-overflow.
22236 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22239 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22241 * process.c (Fmake_network_process): Use socklen_t, not int,
22242 where POSIX says socklen_t is required in portable programs.
22243 This fixes a porting bug on hosts like 64-bit HP-UX, where
22244 socklen_t is wider than int (Bug#8277).
22245 (Fmake_network_process, server_accept_connection):
22246 (wait_reading_process_output, read_process_output):
22249 * process.c: Rename or move locals to avoid shadowing.

22251 (read_process_output_error_handler, exec_sentinel_error_handler):
22252 Rename or move locals.

22256 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22257 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22259 Make tparam.h and terminfo.c consistent.
22260 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22261 Include tparam.h instead, since it declares them.
22262 * cm.h (PC): Remove extern decl; tparam.h now does this.
22263 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22264 * terminfo.c: Include tparam.h, to check interfaces.
22265 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22266 (tparam): Adjust signature to match interface in tparam.h;
22267 this removes some undefined behavior. Check that outstring and len
22268 are zero, which they always are with Emacs.
22269 * tparam.h (PC, BC, UP): New extern decls.
22271 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22272 (xftfont_open): Rename locals to avoid shadowing.
22274 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
22275 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
22276 (OTF_TAG_SYM): Omit macro if not needed.

22284 * xml.c (make_dom): Now static.
22286 * composite.c (composition_compute_stop_pos): Rename local to
22288 (composition_reseat_it): Remove unused locals.
22289 (find_automatic_composition, composition_adjust_point): Likewise.
22290 (composition_update_it): Mark var as initialized.
22291 (find_automatic_composition): Mark vars as initialized,
22292 with a FIXME (Bug#8290).
22294 character.h: Rename locals to avoid shadowing.
22295 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22296 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22297 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22298 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22299 to avoid shadowing.
22301 * textprop.c (property_change_between_p): Remove; unused.
22303 * intervals.c (interval_start_pos): Now static.
22305 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

22308 Rename locals to avoid shadowing.
22310 * sound.c (wav_play, au_play, Fplay_sound_internal):
22311 Fix pointer signedness.
22312 (alsa_choose_format): Remove unused local var.
22313 (wav_play): Initialize a variable to 0, to prevent undefined
22314 behavior (Bug#8278).
22316 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22318 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22320 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22321 clobbering (Bug#8298).
22322 * sysdep.c (sys_subshell): Likewise.
22323 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22325 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22326 This should get cleaned up, so that child_setup has the
22327 same signature on all platforms.
22329 * callproc.c (call_process_cleanup): Now static.
22330 (relocate_fd): Rename locals to avoid shadowing.
22332 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22334 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22335 not to be necessary, and produces flickering.
22337 2011-03-20 Glenn Morris <rgm@gnu.org>
22339 * config.in: Remove file.
22341 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
22343 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
22344 are now in src/globals.h.
22345 (syms_of_minibuf): Remove spurious & from previous change.
22347 2011-03-20 Leo Liu <sdl.web@gmail.com>
22349 * minibuf.c (completing-read-function): New variable.
22350 (completing-read-default): Rename from completing-read.
22351 (completing-read): Call completing-read-function.
22353 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
22355 * xfaces.c (Fx_load_color_file):
22356 Read color file from absolute filename (bug#8250).
22358 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
22360 * makefile.w32-in: Update dependencies.
22362 2011-03-17 Eli Zaretskii <eliz@gnu.org>
22364 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

22370 * process.c (make_serial_process_unwind, send_process_trap):
22371 (sigchld_handler): Now static.
22373 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
22374 That way, the code declares only the vars that it needs.
22375 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
22376 * s/cygwin.h (PTY_ITERATION): Likewise.
22377 * s/darwin.h (PTY_ITERATION): Likewise.

22381 * process.c (allocate_pty): Don't declare stb unless it's needed.
22383 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
22384 (CONSTANTLIM): Remove; unused.
22385 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
22386 Define only if needed.
22388 * unexelf.c (unexec): Name an expression,
22389 to avoid gcc -Wbad-function-cast warning.
22390 Use a different way to cause a compilation error if anyone uses
22391 n rather than nn, a way that does not involve shadowing.
22392 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22394 * deps.mk (unexalpha.o): Remove; unused.
22396 New file unexec.h, the (simple) interface for unexec (Bug#8267).
22397 * unexec.h: New file.
22398 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
22399 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
22400 Depend on unexec.h.
22401 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
22402 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
22403 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
22404 Change as necessary to match prototype in unexec.h.
22406 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
22408 (back_comment, skip_chars): Mark vars as initialized.

22416 * print.c (Fredirect_debugging_output): Fix pointer signedess.
22418 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
22419 warning when compiling print.c.

22422 instead of using an uninitialized var.
22423 (font_sort_entities): Mark var as initialized.
22425 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
22427 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

22439 * floatfns.c (domain_error2): Define only if needed.
22440 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
22442 * alloc.c (mark_backtrace): Move decl from here ...

22451 * callint.c (quotify_arg, quotify_args): Now static.
22452 (Fcall_interactively): Rename locals to avoid shadowing.
22453 Use const pointer when appropriate.
22455 * lisp.h (get_system_name, get_operating_system_release):
22456 Move decls here, to check interfaces.
22457 * process.c (get_operating_system_release): Move decl to lisp.h.
22458 * xrdb.c (get_system_name): Likewise.
22459 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
22460 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22461 some of which prompt warnings from gcc -Wbad-function-cast.
22462 (Fformat_time_string, Fencode_time, Finsert_char):
22463 (Ftranslate_region_internal, Fformat):
22464 Rename or remove local vars to avoid shadowing.
22465 (Ftranslate_region_internal): Mark var as initialized.
22467 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
22470 * lisp.h (eassert): Check that the argument compiles, even if
22471 ENABLE_CHECKING is not defined.
22473 * data.c (Findirect_variable): Name an expression, to avoid
22474 gcc -Wbad-function-cast warning.
22475 (default_value, arithcompare, arith_driver, arith_error): Now static.

22482 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
22483 Rename locals to avoid shadowing.
22484 (mark_stack): Move local variables into the #ifdef region where
22486 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
22487 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
22489 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
22490 (GC_STRING_CHARS): Remove; not used.
22491 (Fmemory_limit): Cast sbrk's returned value to char *.
22493 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
22494 avoids undefined behavior in theory.
22496 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22498 Use functions, not macros, for up- and down-casing (Bug#8254).
22499 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22500 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22501 to use the following functions instead of these macros.
22502 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22503 EMACS_INT, since callers assume the returned value fits in int.
22504 (upcase1): Likewise, for UPCASE_TABLE.
22505 (uppercasep, lowercasep, upcase): New static inline functions.
22506 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
22507 the race-condition problem in the old DOWNCASE.
22509 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
22510 Rename locals to avoid shadowing.
22511 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
22512 (regex_compile, re_search_2, re_match_2_internal):
22513 Remove unused local vars.
22514 (FREE_VAR): Rewrite so as not to use empty "else",
22515 which gcc can warn about.
22516 (regex_compile, re_match_2_internal): Mark locals as initialized.
22517 (RETALLOC_IF): Define only if needed.
22518 (WORDCHAR_P): Likewise. This one is never needed, but is used
22519 only in a comment talking about a compiler bug, so put inside
22520 the #if 0 of that comment.
22521 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22522 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
22525 * search.c (boyer_moore): Rename locals to avoid shadowing.
22526 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
22527 (PREV_CHAR_BOUNDARY): Likewise.
22529 * search.c (simple_search): Remove unused var.
22531 * dired.c (compile_pattern): Move decl from here ...

22537 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
22539 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
22540 Rename locals to avoid shadowing.
22541 (Fvertical_motion): Mark locals as initialized.
22543 * casefiddle.c (casify_object, casify_region): Now static.
22544 (casify_region): Mark local as initialized.
22546 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
22548 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22549 New macros, so that the caller can use some names other than
22550 gcpro1, gcpro2, etc.
22551 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22553 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22554 argument, for consistency with GCPRO2_VAR, etc: it is now the
22555 prefix of the variable, not the variable itself. All uses
22557 * dired.c (directory_files_internal, file_name_completion):
22558 Rename locals to avoid shadowing.
22560 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22561 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22562 dired.c's scmp function, had undefined behavior.
22563 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22564 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22565 * buffer.h: ... to here, because these macros use current_buffer,
22566 and the new implementation with inline functions needs to have
22567 current_buffer in scope now, rather than later when the macros
22569 (downcase, upcase1): New static inline functions.
22570 (DOWNCASE, UPCASE1): Reimplement using these functions.
22571 This avoids undefined behavior in expressions like
22572 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22573 from race conditions in accessing the global variables
22574 case_temp1 and case_temp2.
22575 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22576 * lisp.h (case_temp1, case_temp2): Remove their decls.
22577 * character.h (ASCII_CHAR_P): Move from here ...
22578 * lisp.h: ... to here, so that the inline functions mentioned
22579 above can use them.
22581 * dired.c (directory_files_internal_unwind): Now static.
22583 * fileio.c (file_name_as_directory, directory_file_name):
22584 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
22586 (file_name_as_directory): Use const pointers when appropriate.
22587 (Fexpand_file_name): Likewise. In particular, newdir might
22588 point at constant storage, so make it a const pointer.
22589 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22590 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22592 (Fset_file_times, Finsert_file_contents, auto_save_error):
22593 Rename locals to avoid shadowing.
22595 * minibuf.c (choose_minibuf_frame_1): Now static.
22596 (Ftry_completion, Fall_completions): Rename or remove locals
22597 to avoid shadowing.
22599 * marker.c (bytepos_to_charpos): Remove; unused.
22601 * lisp.h (verify_bytepos, count_markers): New decls,
22602 so that gcc does not warn that these functions aren't declared.
22604 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22605 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22606 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22607 (copy_text): Remove unused local var.
22609 * filelock.c (within_one_second): Now static.
22610 (lock_file_1): Rename local to avoid shadowing.
22612 * buffer.c (fix_overlays_before): Mark locals as initialized.
22613 (fix_start_end_in_overlays): Likewise. This function should be
22614 simplified by using pointers-to-pointers, but that's a different
22616 (switch_to_buffer_1): Now static.
