18 directories. If filename is nil, get directory name (Bug#13932).
19 Use getFilename and getDirectory.
20 (getFilename, getDirectory): New methods for EmacsSavePanel and
22 (ok:): In EmacsOpenPanel, if we can't choose directories, just return.

32 arg text_at_gap_tail. Cancel the code for handling it.
34 * coding.h (struct coding_system): New member eol_seen.
36 * coding.c (detect_ascii): New function.
37 (detect_coding): Set coding->head_ascii and coding->eol_seen only
38 when the source bytes are actually scanned. On detecting for
39 coding_category_utf_8_auto, call detect_ascii instead of scanning
40 source bytes directly.
41 (produce_chars): Call insert_from_gap with the new arg 0.
42 (encode_coding): Likewise.

68 2013-03-14 Eli Zaretskii <eliz@gnu.org>
70 * w32term.c (w32_read_socket) <WM_WINDOWPOSCHANGED>: Remove old
71 and incorrect code. Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE
73 (w32fullscreen_hook): If the frame is visible, reset
74 f->want_fullscreen flag after changing the frame size. If the
75 frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
78 2013-03-13 Daniel Colascione <dancol@dancol.org>
80 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
81 too so that these builds can use Cygwin's file conversion
82 functions. (We've been building and linking cygw32.o all along
83 and just not using it.)
85 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
87 File synchronization fixes (Bug#13944).
88 * Makefile.in (LIB_FDATASYNC): New macro.
90 * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
91 * fileio.c (Fwrite_region, write_region_inhibit_fsync):
92 Don't worry about HAVE_FSYNC, since a substitute fsync is
93 available if the system lacks one.
94 (Fwrite_regin): Retry fsync if interrupted.
96 2013-03-13 Eli Zaretskii <eliz@gnu.org>
98 * w32term.c (w32_read_socket): If the Emacs frame is being
99 activated, call w32fullscreen_hook, to make sure the new frame
100 dimensions are in effect. (Bug#13937)
102 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
104 * xdisp.c (init_iterator): Simplify because both character and byte
105 positions are either specified or -1. Add eassert. Adjust comment.
106 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
107 character and byte positions can be obtained from marker.
109 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>

124 a function pointer type; the C Standard requires this.
126 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
127 Include <sys/param.h> unconditionally, as that works elsewhere and
128 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
129 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
132 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>

161 common file dialog code.
163 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
164 can just use du like other systems.
166 * coding.c (from_unicode_buffer): Declare.
167 * coding.c (from_unicode_buffer): Implement.
169 2013-03-10 Stefan Monnier <monnier@iro.umontreal.ca>

208 * insdel.c (adjust_after_replace): Make it public. New arg
210 (adjust_after_insert): Call adjust_after_replace with the new arg
213 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
215 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
216 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
217 from Elisp via unread-command-events.
219 * keyboard.c (access_keymap_keyremap): Accept nil return value from
220 functions to mean "no change".
222 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
224 region-cache.c, scroll.c, search.c: Use bool for booleans.

227 * search.c (struct regexp_cache, compile_pattern_1)
228 (compile_pattern, string_match_1, search_command)
229 (trivial_regexp_p, search_buffer, Freplace_match, match_limit)
230 (search_regs_saved, Fregexp_quote):
231 Use bool for boolean.
232 * region-cache.c (region_cache_forward, region_cache_backward):
233 Fix comments to match code: these functions return int, not boolean.
235 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
237 * search.c (find_newline): Accept start and end byte positions
238 as arguments and allow -1 if not known.

240 * lisp.h (find_newline, find_newline_no_quit): Adjust prototype.
241 * bidi.c (bidi_find_paragraph_start): Pass byte position to

244 Adjust call to find_newline.
245 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

249 (get_visually_first_element, move_it_vertically_backward): Likewise.
250 Obtain byte position from the display iterator, where appropriate.
252 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>

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

277 when you need just to move to the previous buffer position.
278 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
280 2013-03-07 Eli Zaretskii <eliz@gnu.org>

301 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>
303 * lisp.h (list2i, list3i): New functions.

353 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
355 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
356 * sysdep.c (list_system_processes)
357 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
358 Make it a stub in this case; otherwise the build might fail,
359 and this code hasn't been tested on such hosts anyway.
360 Problem reported by Nelson H. F. Beebe in
361 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
362 and analyzed by Jérémie Courrèges-Anglas in
363 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
365 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
367 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
368 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
369 (get_visually_first_element, move_it_vertically_backward): Ajust users.
370 * bidi.c (bidi_find_paragraph_start): Likewise.
371 * indent.c (vmotion): Likewise.
373 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
375 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
376 * filelock.c: Include <c-ctype.h>.
377 (MAX_LFINFO): New top-level constant.
378 (lock_info_type): Remove members pid, boot_time. Add members at,
379 dot, colon. Change user member to be the entire buffer, not a
380 pointer. This allows us to handle the case where a foreign
381 pid or boot time exceeds the local range. All uses changed.
382 (LINKS_MIGHT_NOT_WORK): New constant.
383 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
384 (defined_WINDOWSNT): Remove.
385 (MAKE_LOCK_NAME, file_in_lock_file_name):
386 Always use .#FILE (not .#-FILE) for the file lock,
387 even if it is a regular file.
388 (rename_lock_file): New function.
389 (create_lock_file): Use it.
390 (create_lock_file, read_lock_data):
391 Prefer a symbolic link for the lock file, falling back on a
392 regular file if symlinks don't work. Do not try to create
393 symlinks on MS-Windows, due to security hassles. Stick with
394 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
395 link, rename, unlink, mkstemp) when creating locks, as a GNUish
396 host may be using a Windowsish file system, and cannot use
397 MS-Windows-only system calls. Fall back on mktemp if mkstemp
398 doesn't work. Don't fail merely because of a symlink-contents
399 length limit in the current file system; fall back on regular
400 files. Increase the symlink contents length limit to 8 KiB, this
401 should be big enough for any real use and doesn't crunch the
403 (create_lock_file, lock_file_1, read_lock_data):
404 Simplify allocation of lock file buffers now that they fit in 8 KiB.
405 (lock_file_1): Return error number, not bool. All callers changed.
406 (ELOOP): New macro, if not already defined.
407 (read_lock_data): Return size of lock file contents, not Lisp object.
408 All callers changed. Handle a race condition if some other process
409 replaces a regular-file lock with a symlink lock or vice versa,
410 while we're trying to read the lock.
411 (current_lock_owner): Parse contents more carefully, to help avoid
412 confusing a regular-file lock with some other application's use
413 of the file. Check for lock file contents being too long, or
414 not parsing correctly.
415 (current_lock_owner, lock_file):
416 Allow foreign pid and boot times that exceed the local range.
417 (current_lock_owner, lock_if_free, lock_file):
418 Simplify allocation of lock file contents.
419 * w32.c (sys_rename_replace): New function, containing most of
420 the contents of the old sys_rename.
421 (sys_rename): Use it.
422 (fchmod): New dummy function.
423 * w32.h (sys_rename_replace, fchmod): New decls.
425 2013-03-05 Eli Zaretskii <eliz@gnu.org>
427 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
428 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
429 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
430 <dmantipov@yandex.ru>.
432 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
434 * composite.c (get_composition_id, fill_gstring_header):
435 Use make_uninit_vector where appropriate.
436 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
437 * xselect.c (clean_local_selection_data): Likewise.
439 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
441 Fix misuse of ImageMagick that caused core dump (Bug#13846).
442 * image.c (imagemagick_load_image): Calculate height and width
443 after flattening the image, not before.
445 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
447 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
448 * ftfont.c (ftfont_shape_by_flt): Likewise.
449 * w32uniscribe.c (uniscribe_shape): Likewise.
451 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
453 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
454 The old approach, which fell back on DIR/.#FILE.0 through
455 DIR/.#FILE.9, had race conditions that could not be easily fixed.
456 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
457 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
458 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
459 because the locking mechanism was never reliable in that case).
460 This patch fixes this and other bugs discovered by a code
461 inspection that was prompted by
462 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
463 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
464 to avoid interoperability problems between the MS-Windows and
465 non-MS-Windows implementations. MS-Windows and non-MS-Windows
466 instances of Emacs now ignore each others' locks.
467 * filelock.c (defined_WINDOWSNT): New constant.
468 (MAKE_LOCK_NAME, fill_in_lock_file_name):
469 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
470 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
471 regular files on MS-Windows hosts.
472 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
473 Use SAFE_ALLOCA to avoid problems with long file names.
474 (MAX_LFINFO): Now a local constant, not a global macro.
475 (IS_LOCK_FILE): Remove.
476 (lock_file_1): Don't inspect errno if symlink call succeeds;
478 (lock_file): Document that this function can return if lock
480 (lock_file): Don't access freed storage.

489 (validate_interval_range, Fadd_text_properties)
490 (Fremove_text_properties): Prefer bool to int when either works.
492 2013-03-02 Eli Zaretskii <eliz@gnu.org>
494 * textprop.c (Fadd_text_properties, Fremove_text_properties):
495 If the interval tree changes as a side effect of calling
496 modify_region, re-do processing starting from the call to
497 validate_interval_range. (Bug#13743)
499 2013-02-28 Eli Zaretskii <eliz@gnu.org>
501 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
504 2013-02-27 Eli Zaretskii <eliz@gnu.org>
506 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
507 _SH_DENYRW flag, instead of emacs_open, to deny any other process
508 access to the lock file until it is written and closed.
511 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
513 * callint.c (Qcall_interactively):

523 Minor textprop integer cleanup.
524 * intervals.h, textprop.c (add_text_properties_from_list):

535 (Fremove_list_of_text_properties):
536 Reindent do-while as per GNU style.
538 2013-02-25 Eli Zaretskii <eliz@gnu.org>
540 Implement CLASH_DETECTION for MS-Windows.
542 * filelock.c [WINDOWSNT]: Include w32.h.
543 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
544 function of that name. Up-case the macro arguments.
545 (IS_LOCK_FILE): New macro.
546 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
547 (create_lock_file): New function, with body extracted from
549 [WINDOWSNT]: Implement lock files by writing a regular file with
550 the lock information as its contents.
551 (read_lock_data): New function, on Posix platforms just calls
553 [WINDOWSNT]: Read the lock info from the file.
554 (current_lock_owner): Call read_lock_data instead of calling
555 emacs_readlinkat directly.
556 (lock_file) [WINDOWSNT]: Run the file name through
559 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
560 just check if the process by that PID exists.
562 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
563 also present, as doing so will fail to error out if the file
566 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
568 * textprop.c (Fadd_text_properties, Fremove_text_properties)
569 (Fremove_list_of_text_properties): Skip all of the intervals in
570 the region between START and END that already have resp. don't
571 have the requested properties, not just the first one.
572 Add assertions that the loop afterwards always modifies the
573 properties. (Bug#13743)
575 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
577 * callint.c (Fcall_interactively): Use the right lexical environment

585 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
586 (START_FILES): Remove. All uses removed.
587 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
588 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
589 (buildobj.h): Use it.

602 (make_hdr): Use DATA_START instead of start_of_data.
603 * vm-limit.c: Move most of mem-limits.h's contents here.
604 (data_start): New decl. It's OK if this is approximate,
605 so simplify-away some unnecessary exactness.
606 (POINTER): Remove; all uses removed.
607 (data_space_start): Now char *, to avoid casts.
608 (exceeds_lisp_ptr): New function, replacing the old
609 EXCEEDS_LISP_PTR macro. All uses changed.
610 (check_memory_limits): Simplify and remove casts.
611 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

616 * xdisp.c (set_message): Only check for debug-on-message if STRING
617 is a string. (Bug#13797)
619 2013-02-24 Paul Eggert <eggert@cs.ucla.edu>
621 Fix regression introduced by July 10 filelock.c patch.
622 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
623 2012-07-10 patch to this file. Reported by Eli Zaretskii in
624 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
625 and diagnosed by Andreas Schwab in
626 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
628 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
630 Assume C89 or better.
631 * ralloc.c (SIZE, POINTER, NIL):
632 * vm-limit.c (POINTER):
633 Remove, replacing all uses with C89 equivalents. These old
634 symbols were present only for porting to pre-C89 platforms.
636 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
638 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
639 This avoids warning messages reported as part of Bug#13546.
641 2013-02-21 Ken Brown <kbrown@cornell.edu>
643 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
645 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
647 * sheap.c (report_sheap_usage): Prefer message1_nolog.
649 * keyboard.c (Qcommand_execute): New var.
650 (command_loop_1, read_char): Use it.
651 (Fcommand_execute): Remove, replace by an Elisp implementation.
652 (syms_of_keyboard): Adjust accordingly.
654 2013-02-19 Daniel Colascione <dancol@dancol.org>
656 * sheap.c (report_sheap_usage): Use message, not message1, so
657 that we don't try to create a buffer while we're in the middle
658 of dumping Emacs. Explain why.
660 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
662 * search.c (find_newline): Return byte position in bytepos.
664 (find_next_newline_no_quit, find_before_next_newline):
665 Add bytepos argument.
666 * lisp.h (find_newline, find_next_newline_no_quit)
667 (find_before_next_newline): Adjust prototypes.

672 (get_visually_first_element, move_it_vertically_backward):
673 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
675 2013-02-19 Eli Zaretskii <eliz@gnu.org>
677 * w32proc.c (new_child): Avoid leaking handles if the subprocess
678 resources were not orderly released.
680 2013-02-17 Eli Zaretskii <eliz@gnu.org>
682 * xdisp.c (x_draw_vertical_border): For a window that is neither
683 the leftmost nor the rightmost, redraw both the left and the right
684 vertical borders. (Bug#13723)
686 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>
688 * xml.c (init_libxml2_functions):

699 2013-02-17 Jan Djärv <jan.h.d@swipnet.se>
701 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...
702 * frame.c (syms_of_frame): ... to here.
704 2013-02-16 Eli Zaretskii <eliz@gnu.org>
706 * w32.c (sys_chown): Remove unused function.
708 * w32term.c <input_signal_count>: Declare 'volatile'
709 unconditionally. (Bug#9066)
711 * w32.c (set_errno): Reset h_errno and don't set it to any other
712 value. Set errno instead.
713 (check_errno): Reset h_errno.
714 (sys_socket, socket_to_fd, sys_bind, sys_connect)
715 (sys_gethostname, sys_getservbyname, sys_getpeername)
716 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
717 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set

721 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
723 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
725 2013-02-15 Eli Zaretskii <eliz@gnu.org>
727 * keyboard.c (read_char): Fix calculation of auto-save time out
728 when auto-save-timeout is less than 4. (Bug#13720)
730 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

735 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
736 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
737 make sure errno is set to an appropriate value. (Bug#13546)
738 (socket_to_fd): Add assertion against indexing fd_info[] with a
739 value that is out of bounds.
740 (sys_accept): If fd is negative, do not set up the child_process
741 structure for reading.
743 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
745 * composite.c (fill_gstring_header): Remove useless prototype.

752 (get_overlay_arrow_glyph_row, display_mode_element):
753 (decode_mode_spec_coding, message3):
754 * xfaces.c (face_at_string_position): Use bool for booleans.
757 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
759 Fix AIX port (Bug#13650).
760 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
761 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
762 was #undeffed earlier, so it cannot be used as a macro here.
763 Use the constant and not the macro.
765 2013-02-15 Eli Zaretskii <eliz@gnu.org>
767 * w32proc.c (new_child): If no vacant slots are found in
768 child_procs[], make another pass looking for slots whose process
769 has exited or died. (Bug#13546)
771 * w32.c (sys_pipe): When failing due to file descriptors above
772 MAXDESC, set errno to EMFILE.
773 (_sys_read_ahead): Update cp->status when failing to read serial
774 communications input, so that the status doesn't stay at
775 STATUS_READ_IN_PROGRESS. (Bug#13546)
777 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
779 * gtkutil.c (tb_size_cb): New function.
780 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
782 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
784 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
787 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
789 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
791 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
793 * font.c (font_range): Add pos_byte argument. Adjust comment
795 * font.h (font_range): Adjust prototype.
796 * composite.c (autocmp_chars): Pass byte position to font_range.
797 Break long line. Remove useless prototype and format comment.
799 2013-02-13 Glenn Morris <rgm@gnu.org>
801 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
803 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
805 Improve AIX port some more (Bug#13650).
806 With this, it should be as good as it was in 23.3, though it's
807 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
808 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
809 * unexaix.c (start_of_text): Remove.
810 (_data, _text): Declare as char[], not int, as AIX manual suggests.
811 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
812 (orig_load_scnptr, orig_data_scnptr):
813 Now off_t, not long, since they are file offsets.
814 (make_hdr): Use _data, not start_of_data ().
815 This is the key part of the fix.
816 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
817 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
819 * pre-crt0.c (data_start): Initialize to 1.
820 This ports to compilers that optimize the external declaration
821 'int x = 0;' as if it were 'int x;' to shrink the executable.
823 Improve AIX port (Bug#13650).
824 This doesn't fix the bug, but it makes progress: Emacs builds now.
825 * unexaix.c: Include inttypes.h, stdarg.h.
826 (report_error, report_error_1): Mark as _Noreturn.
827 (report_error): Don't report the wrong errno.
828 (report_error_1): Now varargs. All callers changed.
829 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
830 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
831 (write_ptr): Use %p to print address rather than %lx and a cast
832 to unsigned long. Grow buffer a bit, to be safer.
834 2013-02-13 Eli Zaretskii <eliz@gnu.org>
836 * bidi.c (bidi_resolve_neutral): After finding the next
837 non-neutral character, accept NEUTRAL_ON type as well, because
838 directional control characters, such as LRE and RLE, have their
839 type converted to that by bidi_resolve_weak. This avoids aborts
840 when LRE/RLE follows a run of neutrals.
841 (bidi_move_to_visually_next): Assert that return value of
842 bidi_peek_at_next_level is non-negative. Negative values will
845 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
847 Minor getenv-related fixes.
848 * callproc.c (Fcall_process_region) [!DOS_NT]:
849 Avoid unnecessary duplicate call to getenv.
850 * callproc.c (init_callproc):
851 * dispnew.c (init_display):
852 * sysdep.c (sys_subshell):
853 Omit unnecessary cast of getenv or egetenv.
855 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
857 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
860 2013-02-12 Eli Zaretskii <eliz@gnu.org>
862 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
864 (display_line): Set w->region_showing to the value of
865 it->region_beg_charpos, not to -1. This fixes redisplay
866 optimization when cursor is moved up after M->. (Bug#13623)
868 (try_scrolling): Scroll text up more if point is too close to ZV
869 and inside the scroll margin. This makes sure point is moved
870 outside the scroll margin in these cases.
872 * window.h (struct window): region_showing can no longer be
875 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
877 Tune by using memchr and memrchr.
878 * doc.c (Fsnarf_documentation):
879 * fileio.c (Fsubstitute_in_file_name):
880 * search.c (find_newline, scan_newline):
881 * xdisp.c (pos_visible_p, display_count_lines):
882 Use memchr and memrchr rather than scanning byte-by-byte.
883 * search.c (find_newline): Rename from scan_buffer.
884 Omit first arg TARGET, as it's always '\n'. All callers changed.
886 Clean up read_key_sequence a tiny bit more.
887 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
888 (read_key_sequence): Remove unused locals.
890 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
892 Clean up read_key_sequence a bit; reread active keymaps after first event.
893 * keyboard.c (read_char, read_char_x_menu_prompt)
894 (read_char_minibuf_menu_prompt):
895 Replace nmaps+maps with a single `map' arg.
896 (follow_key): Operate on a single map.
897 (active_maps): New function.
898 (test_undefined): Also return true for nil bindings.
899 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
900 a single (composed) keymap. Remember `first_event' to choose the right
901 set of active keymaps. Recompute the set of keymaps after receiving
902 the first event. Remove GOBBLE_FIRST_EVENT.
903 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
904 * keyboard.h (read_char): Update declaration.
905 * lread.c (read_filtered_event): Adjust call to read_char.
907 2013-02-11 Eli Zaretskii <eliz@gnu.org>
909 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
910 Don't use the limitation on backwards movement when lines are truncated
911 in the window. (Bug#13675)
913 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
915 * marker.c (set_marker_internal): If desired position is passed
916 as a marker, avoid call to buf_charpos_to_bytepos.
917 * window.c (Fset_window_point): Omit redundant type checking.
918 (Fset_window_start): Likewise. Format comment.
919 (window_scroll_pixel_based): Use set_marker_restricted_both
920 with character and byte positions obtained from an iterator.
921 (Fset_window_configuration): Use set_marker_restricted_both.
922 * xdisp.c (message_dolog): Likewise.
924 2013-02-10 Eli Zaretskii <eliz@gnu.org>
926 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
927 When text lines are longer than window's screen lines, don't move back
928 too far. This speeds up some redisplay operations. (Bug#13675)
930 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
932 * syntax.c (scan_sexps_forward): Fix byte position calculation
933 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
935 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
937 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
940 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
942 Minor hashing refactoring.
943 * fns.c (SXHASH_REDUCE): Move to lisp.h.
944 (sxhash_float): Return EMACS_UINT, for consistency with the other
946 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
947 non-static inline function and therefore can't use static vars.
948 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
949 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
950 with the other hash functions.
952 2013-02-09 Eli Zaretskii <eliz@gnu.org>
954 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
955 XXXXXX part of the temporary file pattern is not downcased even
956 when w32-downcase-file-names is non-nil. (Bug#13661)
958 * xdisp.c (decode_mode_spec): Remove handling of %t.
960 * msdos.c (careadlinkatcwd): Remove.
962 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
964 * lread.c (skip_dyn_bytes): New function (bug#12598).
965 (read1): Use it. Use getc instead of READCHAR to read bytes.
966 (load_each_byte): Remove. Update users.
968 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
970 * search.c (scan_buffer): Calculate end byte position just once.

972 (search_command): Use eassert.
973 * syntax.c (struct lisp_parse_state): New member location_byte.
974 (scan_sexps_forward): Record from_byte and avoid redundant
975 character to byte position calculation ...
976 (Fparse_partial_sexp): ... here. Break too long line.
978 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
980 * lisp.h (make_uninit_vector): New function.
981 * alloc.c (Fvector, Fmake_byte_code):

999 * coding.c (Fdefine_coding_system_internal): Use AREF where
1000 argument is known to be a vector.
1001 * fns.c (Flocale_info): Likewise for ASET.
1002 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1003 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1005 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1007 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1010 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
1011 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
1012 updateCollectionBehaviour.
1014 * nsterm.m (NEW_STYLE_FS): Remove.
1015 (ns_last_use_native_fullscreen): New variable.
1016 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
1017 (x_set_window_size): Do not take title bar and tool bar into account
1018 if isFullscreen returns YES.
1019 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1020 (check_native_fs): New function.
1021 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
1022 (ns_term_init): Remove NEW_STYLE_FS.
1023 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
1024 and tool bar if isFullscreen returns NO.
1025 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
1026 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
1027 with HAVE_NATIVE_FS.
1028 (window:willUseFullScreenPresentationOptions:): New method.

1033 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
1034 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
1035 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
1036 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
1037 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1038 (syms_of_nsterm): Add ns-use-native-fullscreen.
1040 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1042 * fileio.c (Qchoose_write_coding_system): Now static.
1044 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1046 * xdisp.c (window_buffer_changed): region_showing can be negative,
1047 which still means region is being displayed.
1048 (redisplay_internal): Resurrect code that forced redisplay of the
1049 whole window when showing region and the mark has changed.
1050 Record the new mark position to allow redisplay optimizations.
1051 (display_line): If it->region_beg_charpos is non-zero, set the
1052 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1054 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1055 not bitfield of 1 bit.
1057 2013-02-03 Daniel Colascione <dancol@dancol.org>
1059 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1060 daemon mode works on cygw32 when Emacs is installed and not just
1063 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1065 Avoid file time stamp bug on MS-Windows (Bug#13149).
1066 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1067 as FAT32 doesn't update time stamps when truncating them.
1068 Also, check that a file time stamp is not a multiple of 100 ns;
1069 this should catch all instances of the problem on MS-Windows,
1070 as its native file system resolution is 100 ns or worse, and
1071 checking for a non-multiple of 100 ns should impose only a small
1072 overhead on systems with ns resolution.
1074 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1076 Avoid encoding file names on MS-Windows when they need to be run
1077 through dostounix_filename.
1078 * w32.c (normalize_filename): Accept an additional argument
1079 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1080 downcase it even if w32-downcase-file-names is non-nil.
1081 (dostounix_filename): Accept an additional argument MULTIBYTE and
1082 pass it to normalize_filename.
1083 (emacs_root_dir): Adjust.
1085 * msdos.h (dostounix_filename): Adjust prototype.
1087 * w32.h (dostounix_filename): Adjust prototype.
1089 * msdos.c (dostounix_filename): Accept an additional argument and
1091 (init_environment): Adjust callers of dostounix_filename.
1093 * fileio.c (Ffile_name_directory, file_name_as_directory)
1094 (directory_file_name, Fexpand_file_name)
1095 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1097 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1099 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1100 variables, as egetenv is case-insensitive for DOS_NT.
1102 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1103 with an encoded file name.
1105 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1106 Adjust calls to dostounix_filename.
1108 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1110 * unexw32.c (unexec): Adjust call to dostounix_filename.
1112 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1114 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1117 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1120 * callproc.c (Fcall_process): Make sure program name in PATH and
1121 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1122 is passed to exec/spawnve, which fails unless the file-name
1125 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1126 even if w32-quote-process-args is nil.
1128 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1130 Fix timestamp bug when write-region appends nothing (Bug#13149).
1131 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1132 the file's time stamp doesn't change if Emacs happens to write nothing
1133 to the file, and on a buggy file system this could cause Emacs to
1134 incorrectly infer that the file system doesn't have the bug.
1135 Avoid this problem by inhibiting the inference in this case.
1137 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1139 * window.h (struct window): Convert base_line_number, base_line_pos
1140 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1141 Convert region_showing member from Lisp_Object to bitfield.
1142 Remove sequence_number member. Adjust comments.
1143 * window.c (sequence_number): Remove.
1144 (make_window): Initialize column_number_displayed.
1145 * print.c (print_object): Follow the printed representation of
1146 frames and print window pointer to distinguish between windows.

1148 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1149 (wset_column_number_displayed, wset_region_showing): Remove.
1150 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1151 (try_scrolling, try_cursor_movement, redisplay_window)
1152 (try_window_reusing_current_matrix, try_window_id, display_line)
1153 (display_mode_lines, decode_mode_spec): Adjust users.
1154 * .gdbinit (pwinx): Do not print sequence_number.
1156 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1158 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1159 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1160 * dired.c: Include <fcntl.h>.
1161 (open_directory): New function, which uses open and fdopendir
1162 rather than opendir. DOS_NT platforms still use opendir, though.
1163 (directory_files_internal, file_name_completion): Use it.
1164 (file_attributes): New function, with most of the old Ffile_attributes.
1165 (directory_files_internal, Ffile_attributes): Use it.
1166 (file_attributes, file_name_completion_stat): First arg is now fd,
1167 not dir name. All uses changed. Use fstatat rather than lstat +
1169 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1170 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1171 (emacs_readlinkat): New function, with much of the old
1172 Ffile_symlink_p, but with an fd argument for speed.
1173 It uses readlinkat rather than careadlinkatcwd, so that it
1174 need not assume the working directory.
1175 (Ffile_symlink_p): Use it.
1176 * filelock.c (current_lock_owner): Use emacs_readlinkat
1177 rather than emacs_readlink.
1178 * lisp.h (emacs_readlinkat): New decl.
1179 (READLINK_BUFSIZE, emacs_readlink): Remove.
1180 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1181 (emacs_norealloc_allocator, emacs_readlink): Remove.
1182 This stuff is moved to fileio.c.
1183 * w32.c (fstatat, readlinkat): New functions.
1184 (careadlinkat): Don't check that fd == AT_FDCWD.
1185 (careadlinkatcwd): Remove; no longer needed.
1187 2013-01-31 Glenn Morris <rgm@gnu.org>
1189 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
1190 (Fwrite_region): Update for new choose_write_coding_system args.
1191 Move the last piece of choose_write_coding_system here. (Bug#13522)
1192 (syms_of_fileio): Add choose-write-coding-system.
1194 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1196 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1197 (sys_close): Zero out the flags for the file descriptor before
1198 closing it. (Bug#13546)
1200 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1201 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1202 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1205 * w32.c (w32_get_long_filename, init_environment, readlink):
1206 Support file names encoded in DBCS codepages.
1207 (readlink): Use the current file-name-coding-system, not the ANSI
1208 codepage, to decode and handle targets of symlinks.
1210 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1212 * w32.c (opendir): Now accepts a 'const char *'.
1214 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1216 Remove obsolete redisplay code. See the discussion at
1217 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1218 * dispnew.c (preemption_period, preemption_next_check): Remove.
1219 (Vredisplay_preemption_period): Likewise.
1220 (update_frame, update_single_window, update_window, update_frame_1):
1221 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1222 used, following the 2012-06-22 change.
1224 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1226 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1228 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1230 * font.c (num_fonts): Remove the leftover from old
1231 debugging code. Adjust comment style here and there.
1232 * insdel.c (insert_1): Remove.
1233 * lisp.h (insert_1): Remove prototype.
1234 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1236 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1238 * w32.c (max_filename_mbslen): New function.
1239 (normalize_filename, readdir): Use it to detect locales where ANSI
1240 encoding of file names uses a double-byte character set (DBCS).
1241 If a DBCS encoding is used, advance by characters using
1242 CharNextExA, instead of incrementing a 'char *' pointer.
1243 Use _mbslwr instead of _strlwr. (Bug#13515)
1245 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1246 request of memory reservation to 1.7GB. (Bug#13065)
1248 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1250 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1251 at check_extra_latin label. (Bug#13505)
1253 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1255 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1256 Avoid redundant calls to strlen.
1258 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1260 Drop async_visible and async_iconified fields of struct frame.
1261 This is possible because async input is gone; for details, see
1262 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1263 * frame.h (struct frame): Remove async_visible and async_iconified
1264 members, convert garbaged to unsigned bitfield. Adjust comments.
1265 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1266 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1267 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1268 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1269 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1271 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1272 properly. Likewise for obscured.
1274 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1277 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1279 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1281 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1282 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1284 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1286 * xdisp.c (message2, message2_nolog): Remove functions.
1287 (message3, message3_nolog): Extract nbytes and multibyteness directly
1288 from the string. Change all callers.
1289 (message3_nolog): Don't set message_enable_multibyte since set_message
1290 will reset it anyway.
1291 (message1, message1_nolog): Use message3.
1292 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1293 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1294 (set_message): Drop all but the second arg, which has to be a string.
1295 (set_message_1): Simplify now that we know that a1 is NULL and the
1296 second arg is a string.
1297 * frame.h (struct frame): Remove `message_buf' field.
1298 Use glyphs_initialized_p instead.
1299 (FRAME_MESSAGE_BUF): Remove macro.
1300 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1301 * lisp.h (message2, message2_nolog): Remove declarations.
1302 (message3, message3_nolog): Update declarations.
1303 * keyboard.c (read_char_minibuf_menu_text)
1304 (read_char_minibuf_menu_width): Remove vars.
1305 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1306 to correctly handle multibyte strings.
1307 * frame.c (delete_frame): Don't free message_buf any more.
1308 * editfns.c (message_text, message_length): Remove vars.
1309 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1310 * fileio.c (auto_save_error): Use message3 instead of message2.
1311 * dispnew.c (adjust_frame_message_buffer): Remove function.
1313 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1315 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1316 real estate used for the tool bar and the menu bar.
1318 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1320 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1321 hidden buffer is prepared to modification (Bug#13164).
1323 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1325 * window.h (struct window): Change window_end_valid member from
1326 Lisp_Object to a bitfield. Adjust comments.
1327 (wset_window_end_valid): Remove.
1328 * window.c (adjust_window_count): Clear window_end_valid.
1329 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1330 (Fwindow_line_height, set_window_buffer, Frecenter)
1331 (Fsplit_window_internal, Fdelete_other_windows_internal)
1332 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1333 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1334 * xdisp.c (check_window_end, reconsider_clip_changes)
1335 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1336 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1337 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1339 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1341 * xdisp.c (mark_window_display_accurate): Simplify the loop
1342 assuming that the only one of vchild, hchild or buffer window
1343 slots is non-nil. Call mark_window_display_accurate_1 for
1344 the leaf windows only.
1345 (mark_window_display_accurate_1): Always assume leaf window.
1348 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1350 * emacs.c (Qkill_emacs_hook): Now static.
1352 * fileio.c (Finsert_file_contents): Simplify.
1353 Remove unnecessary assignments and tests.
1355 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1357 * w32.c (acl_set_file): Don't test for errors unless
1358 set_file_security returns FALSE. Avoids spurious errors when
1361 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1363 * fileio.c (Finsert_file_contents): Revert code introduced at
1364 2013-01-18 in favor of the simpler and generally better fix.
1365 Save stack space by removing 'buffer' and reusing 'read_buf'
1368 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1370 * lisp.h (eabs): Define unconditionally (Bug#13419).
1371 The old "#if !defined (eabs)" was an unnecessary revenant of back
1372 when this macro was called "abs". Document 'eabs' better.
1374 2013-01-19 Glenn Morris <rgm@gnu.org>
1376 * fns.c (Frandom): Doc fix.
1378 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1380 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1381 segfault when there are lots of overlays.
1383 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1384 when there are lots of overlays.
1385 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1386 for the details and a way to reproduce.
1388 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1390 * fileio.c: Use O_APPEND to append.
1391 This corresponds better to the natural interpretation of "append",
1392 and avoids the need to open the output file twice, or to invoke
1393 lseek when APPEND is neither nil nor a number.
1394 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1395 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1396 file possibly twice, and lseeking to its end; this avoids the
1397 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1398 at the same time: the combination is never needed and apparently
1399 it doesn't work with DOS_NT.
1401 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1402 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1404 Allow floating-point file offsets.
1405 Problem reported by Vitalie Spinu in
1406 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1407 * fileio.c (emacs_lseek): Remove.
1408 (file_offset): New function.
1409 (Finsert_file_contents, Fwrite_region): Use it.
1411 2013-01-19 Chong Yidong <cyd@gnu.org>
1413 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1414 aborting on Fsignal (Bug#13289).
1416 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1418 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1419 set_file_security as failure due to insufficient privileges.

1423 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1425 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1426 The bug was observed on Ubuntu operating inside a virtual machine,
1427 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1428 The workaround introduces a race condition on non-buggy hosts,
1429 but it's an unlikely race and anyway there's a nearly identical
1430 nearby race that can't be fixed.
1431 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1433 (Fwrite_region): Test for file system time stamp bug.
1434 (init_fileio): New function.

1447 Free Lisp_Save_Value object used to pass parameters.
1448 (read_non_regular_quit): Rename to read_contents_quit.
1449 (Finsert_file_contents): Redesign internal file reading loop to adjust
1450 gap and end positions after each read and so help make_gap to work
1451 properly. Do not signal an I/O error too early and so do not leave
1452 not yet decoded characters in a buffer, which was the reason of
1453 redisplay crash. Use list2 to build return value. Adjust comments.
1455 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1457 Close a race when statting and reading files (Bug#13149).
1458 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1459 This avoids a race if the file is renamed between stat and open.
1460 This race is not the problem originally noted in Bug#13149;
1461 see <http://bugs.gnu.org/13149#73> and later messages in the thread.

1874 * terminal.c (Fterminal_live_p): ... and here.
1875 * coding.c (Qmac): Now here because it's only used to denote
1876 end-of-line encoding type.
1877 (syms_of_coding): DEFSYM it.
1878 * frame.h (Qmac): Remove duplicated declaration.
1880 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1882 * window.c (select_window_1): Now static, since it's used only here.
1884 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1886 * window.c (window_body_cols): Subtract display margins from the
1887 window body width on TTYs as well. See
1888 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1889 for the original report.
1891 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1893 * xdisp.c (redisplay_window): Remove inner local variable
1894 because the outer shadowed one has the same meaning.
1895 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1897 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1898 (xg_create_tool_bar): Adjust users.
1900 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1902 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1903 * buffer.c (Fget_buffer_create): Use it to set compact field of
1904 struct buffer_text to avoid accessing an uninitialized value
1905 when compact_buffer is called for the first time.
1906 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1907 (Fset_buffer_modified_p): Use buffer_window_count to check
1908 whether the buffer is displayed in some window.
1909 * xdisp.c (message_dolog): Likewise.
1911 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1913 * w32.c (acl_set_file): If setting the file security descriptor
1914 fails, and the new DACL is identical to the existing one, silently
1915 return success. This fixes problems for users backing up their
1916 own files without having the necessary privileges for setting
1917 security descriptors.
1919 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1921 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1922 after WaitForSingleObject returns normally. This expedites reader
1923 thread shutdown when delete_child triggers it.
1924 (reap_subprocess): More accurate commentary for why we call
1925 delete_child only when cp->fd is negative.
1927 * w32.c (sys_close): Do not call delete_child on a subprocess
1928 whose handle is not yet closed. Instead, set its file descriptor
1929 to a negative value, so that reap_subprocess will call
1930 delete_child on that subprocess when its SIGCHLD arrives.
1931 This avoids closing handles used for communications between sys_select
1932 and reader_thread, which doesn't give sys_select a chance to
1933 notice that the process exited and invoke the SIGCHLD handler for
1936 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1938 * nsfns.m (Fns_do_applescript): Run event loop until script has
1939 been executed (Bug#12969).
1940 (ns_run_ascript): Chech as_script for nil, set to nil after
1943 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1945 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1947 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1949 * w32term.c (w32fullscreen_hook): New function.
1950 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1952 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1954 * fileio.c (Finsert_file_contents): Doc fix.
1956 * w32proc.c (new_child, delete_child, find_child_pid): For a
1957 subprocess, consider its slot being in use as long as its process
1958 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1959 slot when a new process is started immediately after killing
1960 another one, without waiting enough time for the first process to
1961 be reaped and resources allocated for it be orderly freed.
1963 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1965 2012-12-21 Chong Yidong <cyd@gnu.org>
1967 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1969 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1971 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1973 * w32.c (get_name_and_id): Always pass NULL as the first argument
1974 of lookup_account_sid. Avoids crashes with UNC file names that
1975 refer to DFS domains, not to specific machine names. (Bug#12621)
1976 Remove now unused argument FNAME; all callers changed.
1977 (get_file_owner_and_group): Remove now unused argument FNAME; all
1980 2012-12-21 Chong Yidong <cyd@gnu.org>
1982 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1983 error for invalid chars, don't check for a nil return value.
1985 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1987 Avoid calls to CHAR_TO_BYTE if byte position is known.
1988 * editfns.c (make_buffer_string_both): Use move_gap_both.
1989 (Fbuffer_string): Use make_buffer_string_both.
1990 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1992 (buf_bytepos_to_charpos): Likewise.
1993 (charpos_to_bytepos): Remove.
1994 * fileio.c (Finsert_file_contents): Use move_gap_both.
1995 * search.c (Freplace_match): Likewise.
1996 * process.c (process_send_region): Likewise. Use convenient
1997 names for byte positions.
1998 * lisp.h (charpos_to_bytepos): Remove prototype.
1999 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2000 * insdel.c (move_gap): Likewise.
2002 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2004 * xdisp.c (redisplay_internal): Remove now-unused local.
2006 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2008 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2009 (redisplay_internal): Don't bother selecting the frame to get the
2010 proper value of frame-local variables (bug#13225).
2012 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2014 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2015 Rename 4th argument since it may be buffer or string. Adjust comment.
2016 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2018 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2020 * coding.c (Fdetect_coding_region): Do not check start and end with
2021 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2022 (code_convert_region): Likewise.
2024 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2026 * w32.c (acl_get_file, acl_set_file): Run the file name through
2027 map_w32_filename, and resolve any symlinks in the file name, like
2029 (acl_set_file): Call revert_to_self, if any privileges were
2032 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2034 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2035 ($(BLD)/w32.$(O)): Update dependencies.
2037 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2039 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2040 propagate redisplay's scrolling (if any) to the right window.
2041 (redisplay_internal): Use ensure_selected_frame.
2042 (display_mode_lines): Complete last fix.
2043 * window.c (select_window_1): New func, extracted from select_window.
2044 (select_window): Use it.
2045 * window.h (select_window_1): Declare.
2047 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2049 Emulate Posix ACL APIs on MS-Windows.
2050 * w32.c: Include sddl.h and sys/acl.h.
2051 (SDDL_REVISION_1): Define if not already defined.
2052 (g_b_init_get_security_descriptor_dacl)
2053 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
2054 (g_b_init_is_valid_security_descriptor)
2055 (g_b_init_set_file_security): New static flags.

2067 (acl_free, acl_get_file, acl_set_file): New functions.
2069 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
2071 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2073 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2074 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2075 for some of that bug's symptoms can now cause Emacs to abort.
2076 Remove the workaround.
2077 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2078 The bug that caused SIGCHLD to get lost has been fixed, and the
2079 workaround for it can now cause Emacs to abort.
2081 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2083 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2084 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2085 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
2087 2012-12-16 Romain Francoise <romain@orebokech.com>
2089 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2090 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2091 and copy ACL entries of file in addition to SELinux context if set.
2092 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2094 * Makefile.in (LIBACL_LIBS): New macro.
2097 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
2099 * fileio.c (internal_delete_file): Use bool for boolean.
2101 2012-12-15 Eli Zaretskii <eliz@gnu.org>
2103 Fix bug #13079 on MS-Windows with temp files not being deleted.
2104 * w32.h (_child_process): New members input_file and
2106 (register_child): First argument is now pid_t.
2107 (record_infile, record_pending_deletion): New prototypes.
2109 * w32proc.c (new_child): Initialize input_file and
2110 pending_deletion members of the child.
2111 (delete_child): Delete the child's temporary input file, if any,
2112 that is pending deletion.
2113 (register_child): First argument is now pid_t.
2114 (record_infile, record_pending_deletion): New functions.
2115 (reap_subprocess): Fix a typo in DebPrint string.
2116 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2118 * fileio.c (internal_delete_file): Return an int again: non-zero
2119 if delete-file succeeds, zero otherwise.
2121 * lisp.h (internal_delete_file): Adjust prototype.
2123 * callproc.c (Fcall_process): Don't overwrite infile with result
2125 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2126 asynchronous subprocess, record the name of the input file name,
2128 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2129 delete the file, record it as pending deletion when the subprocess
2132 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2134 * editfns.c [HAVE_PWD_H]: Include grp.h.
2136 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
2138 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
2140 Fix permissions bugs with setgid directories etc. (Bug#13125)
2141 * dired.c (Ffile_attributes): Return t as the 9th attribute,
2142 to mark it as a placeholder. The old value was often wrong.
2143 The only user of this attribute has been changed to use
2144 file-ownership-preserved-p instead, with its new group arg.
2145 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
2147 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
2149 * xdisp.c (select_frame_for_redisplay, display_mode_lines):

2152 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2154 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2155 try to get accurate owner and group information from NT file
2156 security APIs. This is to make most callers of 'stat' and
2157 'lstat', which don't need that information, much faster.
2159 * dired.c (Ffile_attributes) [WINDOWSNT]:
2160 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2161 owner and group information from 'lstat'.
2163 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2165 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2166 as that confuses set-auto-coding, so insist on the head-read
2167 returning the full 1024 bytes. Let lseek compute the tail offset;
2168 less work for us. Do not ignore I/O errors when reading the tail.
2170 * xdisp.c: Minor style fixes.
2171 (init_iterator): Hoist assignment out of if-expression.
2172 (markpos_of_region): Callers now test for sign, not for -1.
2174 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
2176 Minor redisplay optimization when the region length is zero.
2177 * xdisp.c (markpos_of_region): New function.
2178 (init_iterator): Do not highlight the region of zero length.
2179 (redisplay_window): Check whether the region is of non-zero length.
2180 (try_cursor_movement): Allow if the region length is zero.
2181 (try_window_reusing_current_matrix, try_window_id): Likewise.
2183 2012-12-13 Eli Zaretskii <eliz@gnu.org>
2185 * search.c (search_buffer): Check the inverse translations of each
2186 character in pattern when the buffer being searched is unibyte.
2189 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2191 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2192 files, fixing a regression from 24.2.
2193 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2195 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2197 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2198 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2199 Remove unnecessary S_ISLNK test, as (contra the comments) this
2200 function can't copy symlinks. Improve quality of error message
2201 when attempting to copy files that are neither regular files nor
2204 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
2206 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.
2207 * gtkutil.c (xg_set_toolkit_scroll_bar_thumb):
2208 * window.c (Frecenter):
2209 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
2210 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
2212 2012-12-12 Daniel Colascione <dancol@dancol.org>
2214 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2215 the dumped Emacs is not a sparse file, greatly improving Cygwin
2216 "make bootstrap" performance.
2218 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
2220 * inotify.c (inotify_callback): Generate an Emacs event for every
2221 incoming inotify event.
2223 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2225 * xdisp.c (handle_face_prop): Fix logic of computing
2226 it->start_of_box_run_p.
2227 (append_space_for_newline): If the glyph row is R2L, reset the
2228 iterator's end_of_box_run_p flag before prepending the space glyph.
2229 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2230 iterator's start_of_box_run_p flag before prepending the stretch.
2231 (append_glyph, produce_image_glyph, append_composite_glyph)
2232 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2233 left_box_line_p and right_box_line_p flags of the glyph for R2L
2234 glyph rows. (Bug#13011)
2236 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2238 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
2239 if changed buffer is not shown in a window.
2240 * insdel.c (prepare_to_modify_buffer): Likewise.
2241 * window.c (replace_buffer_in_windows_safely): Do nothing
2242 if buffer is not shown in a window.

2246 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2248 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
2249 encoded_file_name, which is what it is.
2251 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2253 Consistently use marker_position and marker_byte_position.
2254 * fringe.c (Ffringe_bitmaps_at_pos):

2261 * xdisp.c (message_dolog, with_echo_area_buffer_unwind_data)
2262 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
2263 Replace direct access to marker fields with calls
2264 to marker_position and/or marker_byte_position.
2266 2012-12-11 Juanma Barranquero <lekktu@gmail.com>
2268 * makefile.w32-in (SIG2STR_H): New macro.
2269 (SYSWAIT_H, $(BLD)/emacs.$(O), $(BLD)/process.$(O))
2270 ($(BLD)/w32notify.$(O)): Update dependencies.

2275 Windows file notification functionality unless WINDOWSNT.
2277 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
2280 * w32fns.c (cache_system_info): Initialize the global hinst
2281 variable here so various initialization calls DTRT.
2283 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
2284 (hinst): Remove unneeded extern declaration.
2285 (_start): Remove initialization of above variables; remove
2286 initialization of hinst, as cache_system_info now does that.
2288 * emacs.c (main): Call cache_system_info early in startup; we
2289 previously weren't calling it in Cygwin builds.
2291 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
2292 Teach the autoconf build system how to compile a Windows resource file
2293 and link it to Emacs.

2395 * nsterm.m (fd_handler:): FD_ZERO fds (Bug#13103).
2397 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
2399 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
2400 DWORD_PTR, for compatibility with 64-bit builds.
2402 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
2403 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)

2426 2012-12-08 Eli Zaretskii <eliz@gnu.org>
2428 * w32.c (unsetenv): Return 0 if the input string is too long.
2430 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2432 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
2433 * alloc.c (xputenv): New function.
2434 * dbusbind.c (Fdbus_init_bus):
2436 * xterm.c (x_term_init):
2437 Use xputenv instead of setenv or putenv, to detect memory exhaustion.

2442 Save old TZ value on stack, if it's small.
2443 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
2444 instead, use xputenv+unsetenv to set and restore TZ.
2445 (environbuf): Remove static var. All uses removed.
2446 (Fset_time_zone_rule): Do not save TZ and environ;
2447 no longer needed here.
2448 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
2449 Move to inside set_time_zone_rule; they don't need file scope any more.
2450 (set_time_zone_rule): Maintain the TZ=value string separately.
2451 (syms_of_editfns): Don't initialize initial_tz;
2452 init_editfns now does it.
2453 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
2454 * lisp.h (xputenv): New decl.
2456 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
2458 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
2460 2012-12-08 Eli Zaretskii <eliz@gnu.org>
2462 * w32.c (unsetenv, sys_putenv): New functions.
2464 2012-12-08 Chong Yidong <cyd@gnu.org>

2467 informative (Bug#12992).
2469 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2471 Simplify get_lim_data.
2472 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2473 Remove USG and vlimit methods; no longer used these days.
2474 Add #error catchall just in case.
2476 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2477 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2478 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
2479 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
2480 (deleted_pid_list, Fdelete_process, create_process)
2481 (record_child_status_change, handle_child_signal, deliver_child_signal)

2483 Assume SIGCHLD is defined.
2484 (parse_signal): Remove. All uses removed.
2485 (abbr_to_signal): New static function.
2486 (Fsignal_process): Use it to convert signal names to ints.
2487 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
2488 kill (getpgrp (), ...).

2497 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
2499 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
2500 This will cause a production Emacs to dump core instead of
2503 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2505 * frame.c (make_frame): Do not set window's buffer to t.
2506 * window.c (Fsplit_window_internal): Likewise. Previously it was
2507 used to indicate that the window is being set up. Now we use
2508 set_window_buffer for all new windows, so the condition in ...
2509 (Fset_window_buffer): ... is always true and can be removed.
2511 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2513 Convenient macro to check whether the buffer is hidden.
2514 * buffer.h (BUFFER_HIDDEN_P): New macro.
2515 * frame.c (make_frame): Use it. Adjust comment.
2516 * buffer.c (candidate_buffer): New function.
2517 (Fother_buffer, other_buffer_safely): Use it.
2519 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2521 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2522 if the child process is still running. Instead, exit the wait
2523 loop and return zero. (Bug#13086)
2525 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2527 * frame.h (x_char_width, x_char_height): Remove prototypes.

2541 * callproc.c, process.h (record_kill_process):
2542 New function, containing part of the old call_process_kill.
2543 (call_process_kill): Use it.
2544 This does not change call_process_kill's behavior.
2545 * process.c (Fdelete_process): Use record_kill_process to fix a
2546 race condition that could cause Emacs to lose track of a child.
2548 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2550 Avoid code duplication between prev_frame and next_frame.
2551 * frame.c (candidate_frame): New function. Add comment.
2552 (prev_frame, next_frame): Use it. Adjust comment.
2554 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2556 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2557 fails, signal an error instead of continuing with an empty
2559 Encode expanded temp file pattern before passing it to mkstemp or
2562 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2563 Encode the file name before passing it to dostounix_filename, in
2564 case it will downcase it (under w32-downcase-file-names).
2567 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2569 Minor call-process cleanups.
2570 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2571 at the same time as other platforms, to simplify analysis.
2572 No need for fd0_volatile since we have synch_process_fd.
2573 Avoid needless emacs_close; arg is always negative.
2575 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2577 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2580 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2582 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2583 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2584 and mouse_face_hidden members to a bitfields.
2585 * frame.h (struct frame): Remove set-but-not-used space_width member.
2586 (FRAME_SPACE_WIDTH): Remove.
2587 * nsterm.m, w32term.c, xterm.c: Adjust users.
2588 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2589 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2590 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2591 members to a bitfields.
2593 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2595 Don't let call-process be a zombie factory (Bug#12980).
2596 Fixing this bug required some cleanup of the signal-handling code.
2597 As a side effect, this change also fixes a longstanding rare race
2598 condition whereby Emacs could mistakenly kill unrelated processes,
2599 and it fixes a bug where a second C-g does not kill a recalcitrant
2600 synchronous process in GNU/Linux and similar platforms.
2601 The patch should also fix the last vestiges of Bug#9488,
2602 a bug which has mostly been fixed on the trunk by other changes.
2603 * callproc.c, process.h (synch_process_alive, synch_process_death)
2604 (synch_process_termsig, sync_process_retcode):
2605 Remove. All uses removed, to simplify analysis and so that
2606 less consing is done inside critical sections.
2607 * callproc.c (call_process_exited): Remove. All uses replaced
2608 with !synch_process_pid.
2609 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2610 These take the role of what used to be in unwind-protect arg.
2612 (block_child_signal, unblock_child_signal):
2613 New functions, to avoid races that could kill innocent-victim processes.
2614 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2615 (call_process_kill): Record killed processes as deleted, so that
2616 zombies do not clutter up the system. Do this inside a critical
2617 section, to avoid a race that would allow the clutter.
2618 (call_process_cleanup): Fix code so that the second C-g works again
2619 on common platforms such as GNU/Linux.
2620 (Fcall_process): Create the child process in a critical section,
2621 to fix a race condition. If creating an asynchronous process,
2622 record it as deleted so that zombies do not clutter up the system.
2623 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2624 light of these changes. Omit unnecessary call to emacs_close
2625 before failure, as the unwind-protect code does that.
2626 * callproc.c (call_process_cleanup):
2627 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2628 * process.c (record_deleted_pid): New function, containing
2629 code refactored out of Fdelete_process.
2630 (Fdelete_process): Use it.
2631 (process_status_retrieved): Remove. All callers changed to use
2632 child_status_change.
2633 (record_child_status_change): Remove, folding its contents into ...
2634 (handle_child_signal): ... this signal handler. Now, this
2635 function is purely a handler for SIGCHLD, and is not called after
2636 a synchronous waitpid returns; the synchronous code is moved to
2637 wait_for_termination. There is no need to worry about reaping
2638 more than one child now.
2639 * sysdep.c (get_child_status, child_status_changed): New functions.
2640 (wait_for_termination): Now takes int * status and bool
2641 interruptible arguments, too. Do not record child status change;
2642 that's now the caller's responsibility. All callers changed.
2643 Reimplement in terms of get_child_status.
2644 (wait_for_termination_1, interruptible_wait_for_termination):
2645 Remove. All callers changed to use wait_for_termination.
2646 * syswait.h: Include <stdbool.h>, for bool.
2647 (record_child_status_change, interruptible_wait_for_termination):
2649 (record_deleted_pid, child_status_changed): New decls.
2650 (wait_for_termination): Adjust to API changes noted above.
2652 * bytecode.c, lisp.h (Qbytecode): Remove.
2653 No longer needed after 2012-11-20 interactive-p changes.
2655 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2657 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2658 the scroll margin, move point outside the margin. (Bug#13055)
2660 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2662 * gtkutil.c (my_log_handler): New function.
2663 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2665 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2667 * lisp.h (modify_region): Rename to...
2668 (modify_region_1): ...new prototype.
2669 * textprop.c (modify_region): Now static. Adjust users.
2670 * insdel.c (modify_region): Rename to...
2671 (modify_region_1): ...new function to work with current buffer.
2672 Adjust comment and users. Use true and false for booleans.
2674 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2676 * alloc.c (free_save_value): New function.
2677 (safe_alloca_unwind): Use it.
2678 * lisp.h (free_save_value): New prototype.
2679 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2681 (save_excursion_restore): Adjust to match saved data structure.
2682 Use free_save_value to offload some work from GC. Drop obsolete
2685 2012-12-03 Chong Yidong <cyd@gnu.org>
2687 * fileio.c (Vauto_save_list_file_name): Doc fix.
2689 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2691 * w32fns.c: Remove prototype of atof.
2692 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2694 (file_dialog_callback): Make it UINT_PTR.
2696 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2699 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2700 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2703 2012-12-03 Glenn Morris <rgm@gnu.org>
2705 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2707 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2709 Fix xpalloc confusion after memory is exhausted.
2710 * alloc.c (xpalloc): Comment fix.
2711 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2712 and signals an error, do not clear charset_table_size, as
2713 charset_table is still valid.
2714 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2716 Use execve to avoid need to munge environ (Bug#13054).
2717 * callproc.c (Fcall_process):
2718 * process.c (create_process):
2719 Don't save and restore environ; no longer needed.
2720 * callproc.c (child_setup):
2721 Use execve, not execvp, to preserve environ.
2723 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2725 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2727 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2729 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2730 display for sliced images (Bug#10500).
2732 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2734 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2736 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2737 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2739 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2741 * xdisp.c (window_outdated): Remove eassert since it hits
2742 some suspicious corner cases (see Bug#13007 and Bug#13012).
2743 (mode_line_update_needed): New function.
2744 (redisplay_internal, redisplay_window): Use it.
2745 (ensure_selected_frame): New function.
2746 (redisplay_internal, unwind_redisplay): Use it.
2747 (redisplay_internal): Move comment about buffer_shared...
2748 (buffer_shared_and_changed): ...near to its real use.
2750 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2752 * callproc.c (Fcall_process): Don't misreport vfork failure.
2754 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2756 * callproc.c (Fcall_process): Fix vfork portability problems.
2757 Do not assume that fd[0], count, filefd, and save_environ survive
2758 vfork. Fix bug whereby wrong errno value could be reported for
2759 pipe failure. Some minor cleanups, too, as follows. Move buf and
2760 bufsize to the context where they're needed. Change new_argv to
2761 be of type char **, as this is more convenient and avoids casts.
2762 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2763 Now local constants, not macros.
2765 2012-11-18 Kenichi Handa <handa@gnu.org>
2767 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2768 for the variable "f".
2770 2012-11-13 Kenichi Handa <handa@gnu.org>
2772 * font.c (font_unparse_xlfd): Exclude special characters from the
2773 generating XLFD name.

2798 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2799 highlighting on the frame was cleared. Prevents assertion
2800 violations when repeatedly clicking on the "Top" link of the
2801 "bread-crumbs" in Info buffers.

2810 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2811 were always defined.
2813 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2815 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2816 between bpos_covered and bpos_max. This fixes cursor display when
2817 several display strings follow each other.
2819 * .gdbinit (pgx): If the glyph's object is a string, display the
2820 pointer to string data, rather than the value of the string object
2821 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2823 * indent.c (Fvertical_motion): If the starting position is covered
2824 by a display string, return to one position before that, to avoid
2825 overshooting it inside move_it_to. (Bug#12930)
2827 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2829 * frame.h (struct frame): Remove display_preempted member
2830 since all users are dead long ago.
2831 * nsterm.h (struct x_output): Use the only dummy member.
2832 * w32menu.c (pending_menu_activation): Remove since not
2834 (set_frame_menubar): Adjust user.
2835 * w32term.h (struct x_output): Drop outdated #if 0 code.
2836 (struct w32_output): Use bitfields for explicit_parent,
2837 asked_for_visible and menubar_active members.
2838 Drop unused pending_menu_activation member.
2839 * xterm.h (struct x_output): Drop outdated #if 0 code.
2840 Use bitfields for explicit_parent, asked_for_visible,
2841 has_been_visible and net_wm_state_hidden_seen members.
2843 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2845 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2846 of a literal "/". (Bug#12955)
2847 (gl-stamp): Invoke fc.exe directly, not through cmd.
2849 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
2851 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2852 * dired.c: Assume HAVE_DIRENT_H.
2853 (NAMLEN): Remove, replacing with ...
2854 (dirent_namelen): New function. All uses changed. Use the GNU macro
2855 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2856 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2857 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2858 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2860 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2861 * ndir.h: Rename to ../nt/inc/dirent.h.
2862 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2863 Do not include <dirent.h>; no longer needed.
2864 * w32.c: Include <dirent.h> rather than "ndir.h".
2866 2012-11-23 Chong Yidong <cyd@gnu.org>
2868 * xftfont.c (xftfont_open): Remove duplicate assignment.
2870 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2872 * alloc.c (Fgarbage_collect): Unblock input after clearing
2873 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2874 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2875 * msdos.c (IT_frame_up_to_date): Use it here...
2876 * w32term.c (w32_frame_up_to_date): ...here...
2877 * xterm.c (XTframe_up_to_date): ...and here...
2878 * nsterm.m (ns_frame_up_to_date): ...but not here.
2879 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2881 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2882 Do not check whether GC is in progress.
2884 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2886 * xdisp.c (window_buffer_changed): New function.
2887 (update_menu_bar, update_tool_bar): Use it to
2888 simplify large 'if' statements.
2889 (redisplay_internal): Generalize commonly used
2890 'tail' and 'frame' local variables.
2892 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2894 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2895 with Windows system header.
2897 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2899 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2900 * alloc.c: Assume unistd.h exists.
2901 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
2902 * sysdep.c (get_current_dir_name): Assume getcwd exists.
2903 (getwd) [USG]: Remove; no longer needed.
2904 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2905 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2906 * w32.h (getcwd): Remove decl.
2908 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2910 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2911 Make it set selected_window as well.
2912 (update_tool_bar): Use it.
2914 2012-11-21 Ken Brown <kbrown@cornell.edu>
2916 * emacs.c (main): Set the G_SLICE environment variable for all
2917 Cygwin builds, not just GTK builds. See
2918 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2920 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2922 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2923 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2924 Define for the MSVC compiler.
2926 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2928 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2929 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2930 dostounix_filename. Prevents crashes down the road, because
2931 dostounix_filename assumes it gets a unibyte string.
2932 Reported by Michel de Ruiter <michel@sentient.nl>, see
2933 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
2935 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2937 Conflate Qnil and Qunbound for `symbol-function'.
2938 * alloc.c (Fmake_symbol): Initialize `function' to Qnil.
2939 * lread.c (init_obarray): Set `function' fields to Qnil.
2940 * eval.c (Fcommandp): Ignore Qunbound.
2941 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2942 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2943 Test NILP rather than Qunbound.
2944 (Ffmakunbound): Set to Qnil.
2945 (Fsymbol_function): Never signal an error.
2946 (Finteractive_form): Ignore Qunbound.
2948 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2950 * eval.c (interactive_p): Remove no-longer-used decl.
2952 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2954 * xdisp.c (buffer_shared): Adjust comment.
2955 (buffer_shared_and_changed): New function.
2956 (prepare_menu_bars, redisplay_internal): Use it to
2957 decide whether all windows or frames should be updated.
2958 (window_outdated): New function.
2959 (text_outside_line_unchanged_p, redisplay_window): Use it.
2960 (redisplay_internal): Likewise. Fix indentation.
2962 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2964 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2965 (syms_of_eval): Remove corresponding defsubr.
2966 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2968 2012-11-19 Daniel Colascione <dancol@dancol.org>
2970 * w32fns.c (Fx_file_dialog):
2971 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2972 cygwin_convert_file_name*.
2974 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2975 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2977 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2979 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2981 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2983 * w32select.c: Include w32common.h before w32term.h, so that
2984 windows.h gets included before w32term.h uses some of its
2985 features, see below.
2987 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2989 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2991 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2993 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2995 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2996 (ns_select): Return at once if events are held (Bug#12834).
2998 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3000 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3001 Needed following 2012-10-20 change. (Bug#12902)
3003 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3005 * w32proc.c (waitpid): Remove unused label get_result.
3007 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3009 * makefile.w32-in (SYSWAIT_H): New macro.
3010 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3011 ($(BLD)/sysdep.$(O)): Update dependencies.
3013 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3015 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3016 * callproc.c (relocate_fd): Assume F_DUPFD.
3017 * emacs.c, term.c (O_RDWR): Remove.
3018 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3019 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3020 * nsterm.m: Assume <fcntl.h> exists.
3021 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3022 (create_pty, Fmake_network_process, server_accept_connection)
3023 (wait_reading_process_output, init_process_emacs):
3025 (wait_reading_process_output): Put in a special case for WINDOWSNT
3026 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3027 It's not clear this is needed, but it's a more-conservative change.
3028 (create_process): Assume FD_CLOEXEC.
3029 (create_process, create_pty): Assume O_NOCTTY.
3030 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3031 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3032 Omit if not DOS_NT, since F_GETFL is not defined there.
3033 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3034 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3036 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3037 lack it, since gnulib guarantees this.
3038 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3040 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3042 * w32.c (faccessat): Pretend that directories have the execute bit
3043 set. Emacs expects that, e.g., in files.el:cd-absolute.
3045 * w32proc.c (create_child): Don't clip the PID of the child
3046 process to fit into an Emacs integer, as this is no longer a
3048 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3049 reaping only the process specified by PID argument, if that is
3050 positive. Use PID instead of dead_child to know which process to
3051 reap. Wait for the child to die only if WNOHANG is not in
3053 (sys_select): Don't set dead_child.
3055 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3056 as it is no longer needed.
3058 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3060 (record_child_status_change): Remove the setting of
3061 record_at_most_one_child for the !WNOHANG case.
3063 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3065 Fix problems in ns port found by static checking.
3066 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3067 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3068 not to process group.
3069 (ns_select): Use emacs_write, not write, as that's more robust
3070 in the presence of signals.
3071 (fd_handler:): Check for read errors.
3073 2012-11-16 Glenn Morris <rgm@gnu.org>
3075 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3077 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3079 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3081 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3083 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3084 use the same value of thread handle.
3085 (start_timer_thread): If the timer thread exited (due to error),
3086 clean up by closing the two handles it used. Duplicate the caller
3087 thread's handle here, so it gets duplicated only once, when
3088 launching the timer thread. Set priority of the timer thread, not
3090 (getitimer): Don't duplicate the caller thread's handle here.
3093 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3095 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3098 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3100 Remove no-longer-used pty_max_bytes variable.
3101 * process.c (pty_max_bytes): Remove; unused.
3102 (send_process): Do not set it.
3104 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3106 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3107 Update dependencies.
3109 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3111 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3112 This follows up on the 2012-09-29 patch that removed indirection
3113 for the 'function' field. Reported by Sergey Vinokurov in
3114 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3116 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3118 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3119 different name, as the MS runtime does not have such a function,
3120 and probably never will.) All callers changed. Ignore DIRFD
3121 value if PATH is an absolute file name, to match Posix spec
3122 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3125 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3127 * xdisp.c (echo_area_display, redisplay_internal):
3128 Omit redundant check whether frame_garbaged is set.
3130 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3132 Use faccessat, not access, when checking file permissions (Bug#12632).
3133 This fixes a bug that has been present in Emacs since its creation.
3134 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3135 which must set some sort of record. (Torek's bug report was against
3136 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3137 same common flaw.) See Torek's Usenet posting
3138 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3139 Posted: Fri Apr 8 14:18:56 1983.
3140 * Makefile.in (LIB_EACCESS): New macro.
3142 * callproc.c (init_callproc):
3143 * charset.c (init_charset):
3144 * fileio.c (check_existing, check_executable, check_writable)
3146 * lread.c (openp, load_path_check):
3147 * process.c (allocate_pty):
3149 Use effective UID when checking permissions, not real UID.
3150 * callproc.c (init_callproc):
3151 * charset.c (init_charset):
3152 * lread.c (load_path_check, init_lread):
3153 Test whether directories are accessible, not merely whether they exist.
3154 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3155 * fileio.c (check_existing, check_executable, check_writable)
3157 Use symbolic names instead of integers for the flags, as they're
3159 (check_writable): New arg AMODE. All uses changed.
3160 Set errno on failure.
3161 (Ffile_readable_p): Use faccessat, not stat + open + close.
3162 (Ffile_writable_p): No need to call check_existing + check_writable.
3163 Just call check_writable and then look at errno. This saves a syscall.
3164 dir should never be nil; replace an unnecessary runtime check
3165 with an eassert. When checking the parent directory of a nonexistent
3166 file, check that the directory is searchable as well as writable, as
3167 we can't create files in unsearchable directories.
3168 (file_directory_p): New function, which uses 'stat' on most platforms
3169 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3170 (Ffile_directory_p, Fset_file_times): Use it.
3171 (file_accessible_directory_p): New function, which uses a single
3172 syscall for efficiency.
3173 (Ffile_accessible_directory_p): Use it.
3174 * xrdb.c (file_p): Use file_directory_p.
3175 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3176 * lread.c (openp): When opening a file, use fstat rather than
3177 stat, as that avoids a permissions race. When not opening a file,
3178 use file_directory_p rather than stat.
3179 (dir_warning): First arg is now a usage string, not a format.
3180 Use errno. All uses changed.
3181 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3182 that merely introduced a race.
3183 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3184 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3185 and similarly for the other O_* flags.
3186 * w32.c (sys_faccessat): Rename from sys_access and switch to
3187 faccessat's API. All uses changed.
3188 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3189 (magic_db): Rename from magic_file_p.
3190 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3191 char *, so that we don't have to test for file existence
3192 separately from opening the file for reading. This removes a race
3193 fixes a permission-checking problem, and simplifies the code.
3195 (file_p): Remove; no longer needed.
3197 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3199 Omit glyphs initialization at startup.
3200 * dispnew.c (glyphs_initialized_initially_p): Remove.
3201 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3202 (Fredraw_frame): Move actual code from here...
3203 (redraw_frame): ...to here. Add eassert. Adjust comment.
3204 (Fredraw_display): Use redraw_frame.
3205 * xdisp.c (clear_garbaged_frames): Likewise.
3207 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3209 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3210 passed to pint2str and pint2hrstr to be at most the size of the
3211 frame's decode_mode_spec_buffer. This avoids crashes with very
3212 large values of FIELD_WIDTH argument to decode_mode_spec.
3215 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3217 Fix a race with verify-visited-file-modtime (Bug#12863).
3218 Since at least 1991 Emacs has ignored an mtime difference of no
3219 more than one second, but my guess is that this was to work around
3220 file system bugs that were fixed long ago. Since the race is
3221 causing problems now, let's remove that code.
3222 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3223 whose time stamp is off by no more than a second. Insist that the
3224 file time stamps match exactly.
3226 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3228 * frame.h (struct frame): Convert external_tool_bar member to
3229 1-bit unsigned bitfield.
3230 * termhooks.h (struct terminal): Remove mouse_moved member since
3231 all users are long dead. Adjust comment on mouse_position_hook.
3233 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3235 Simplify by using FOR_EACH_FRAME here and there.
3236 * frame.c (next_frame, prev_frame, other_visible_frames)
3237 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3238 * w32term.c (x_window_to_scroll_bar): Likewise.
3239 * window.c (window_list): Likewise.
3240 * xdisp.c (x_consider_frame_title): Likewise.
3241 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3242 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3243 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3244 * xmenu.c (menubar_id_to_frame): Likewise.
3245 * xselect.c (frame_for_x_selection): Likewise.
3246 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3247 (x_window_to_menu_bar): Likewise.
3248 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3250 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3252 * data.c (Qdefalias_fset_function): Now static.
3254 Another tweak to vectorlike_header change.
3255 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3256 Remove, and replace all uses with ...
3257 (next_in_free_list, set_next_in_free_list):
3258 New functions, which respect C's aliasing rules better.
3260 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3262 * window.c (list4i): Rename from 'quad'. All uses changed.
3263 Needed because <sys/types.h> defines 'quad' on Solaris 10.

3277 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3279 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3280 amount when the scroll margins are too large. When scrolling
3281 backwards in the buffer, give up if cannot reach point or the
3282 scroll margin within a reasonable number of screen lines.
3283 Fixes point position in window under scroll-up/down-aggressively when
3284 point is positioned many lines beyond the window top/bottom.
3287 * ralloc.c (relinquish): If real_morecore fails to return memory
3288 to the system, don't crash; instead, leave the last heap
3289 unchanged and return. (Bug#12774)

3310 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3312 Fix recently introduced crash on MS-Windows (Bug#12839).
3313 * w32term.h (struct scroll_bar): Use convenient header.
3314 (SCROLL_BAR_VEC_SIZE): Remove.
3315 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3317 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3319 Tweak last vectorlike_header change.
3320 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3321 vectorlike object on the free list. This is introduced to avoid
3322 some (but not all) pointer casting and aliasing problems, see
3323 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3324 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

3328 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3330 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3331 been removed, so remove them here also.
3333 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3335 * doc.c (Fdocumentation): Handle new property
3336 dynamic-docstring-function to replace the old ad-advice-info.
3338 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3340 * fns.c (Qeql, hashtest_eq): Now static.
3342 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3344 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3345 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3346 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

3351 Use same hash function for hashfn_profiler as for hash_string etc.
3352 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3353 * lisp.h (sxhash_combine): New inline function, with the contents
3354 of the old SXHASH_COMBINE.
3355 * profiler.c (hashfn_profiler): Use it, instead of having a
3356 special hash function containing a comparison that always yields 1.
3358 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3360 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3361 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3362 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3365 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3367 * image.c (xpm_make_color_table_h): Fix compiler error because
3368 make_hash_table changed.
3370 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3372 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3374 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3376 Use ad-hoc comparison function for the profiler's hash-tables.
3377 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3378 (make_log): Use them.
3379 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3380 call Fequal any more.

3389 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3390 (hash_lookup, hash_remove_from_table): Move assertion checking of
3391 hashfn result here. Check hash-equality before calling cmpfn.

3403 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3404 value of w32-scroll-lock-modifier is neither nil nor one of the
3405 known key modifiers. (Bug#12806)
3407 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3409 Shrink struct vectorlike_header to the only size field.
3410 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3412 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3413 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3414 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3415 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3416 information from the vector header. Adjust comment.

3431 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3432 (large_vectors): Change type to struct large_vector.
3433 (allocate_vector_from_block): Simplify.
3434 (PSEUDOVECTOR_NBYTES): Replace with...
3435 (vector_nbytes): ...new function. Adjust users.
3436 (sweep_vectors): Adjust processing of large vectors.
3437 (allocate_vectorlike): Likewise.
3438 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3439 Add easserts. Adjust XSETPVECTYPESIZE usage.
3440 (allocate_buffer): Use BUFFER_PVEC_INIT.
3441 (live_vector_p): Adjust to match large vector.
3442 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3443 * buffer.h (struct buffer): Add next member.
3444 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3446 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
3447 * fns.c (internal_equal): Adjust to match enum pvec_type change.

3452 (xvecsize): New command.
3454 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3456 * keyboard.c (event_to_kboard): Do not dereference
3457 frame_or_window field of SELECTION_REQUEST_EVENT
3458 and SELECTION_CLEAR_EVENT events (Bug#12814).
3459 * xterm.h (struct selection_input_event): Adjust comment.
3461 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3463 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3464 such as Scroll Lock, if the respective keys are treated as
3465 function keys, not as modifiers. This avoids destroying non-ASCII
3466 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3468 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3470 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3472 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3474 Restore some duplicate definitions (Bug#12814).
3475 This undoes part of the 2012-11-03 changes. Some people build
3476 with plain -g rather than with -g3, and they need the duplicate
3477 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3478 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3479 Define as macros, as well as as enums or as constants.
3481 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3483 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3484 to keypad keys (Bug#12816).
3486 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3488 Minor adjustments of recently-changed frame functions.
3489 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3490 known to be a frame (we're in the FRAMEP branch).
3491 * lisp.h (Qframep): Remove decl. frame.h declares this.
3492 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3493 since they're meant for Lisp fixnum values.
3495 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3497 * window.c (Fwindow_combination_limit): Revert to the only
3498 required argument and adjust docstring as suggested in
3499 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3500 by Martin Rudalics <rudalics@gmx.at>.
3502 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3504 Widely used frame validity and checking functions.
3505 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3506 * frame.c (decode_live_frame, decode_any_frame): New functions.
3507 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3508 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3509 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3510 (Fframe_pointer_visible_p): Use decode_any_frame.
3511 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
3512 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
3513 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3514 (Fframe_focus): Likewise. Allow zero number of arguments.
3516 (frame_buffer_list, frame_buffer_predicate): Remove.
3517 * lisp.h (frame_buffer_predicate): Remove prototype.
3518 * buffer.c (Fother_buffer): Use decode_any_frame.
3519 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3520 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3521 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3522 (Fclose_font, Ffont_info): Use decode_live_frame.
3523 * fontset.c (check_fontset_name): Likewise.
3524 * terminal.c (Fframe_terminal): Likewise.
3525 * w32fns.c (check_x_frame): Likewise.
3526 * window.c (Fminibuffer_window, Fwindow_at)
3527 (Fcurrent_window_configuration): Likewise.
3528 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3529 Likewise. Allow zero number of arguments. Adjust docstring.
3530 * dispnew.c (Fredraw_frame): Likewise.
3531 * xfaces.c (frame_or_selected_frame): Remove.
3532 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3533 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3534 (Fframe_face_alist): Use decode_live_frame.
3535 * xfns.c (check_x_frame): Likewise.
3537 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3539 * window.c (quad): New function.
3540 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3541 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3542 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3543 (Fwindow_line_height): Use it.
3544 (Fwindow_fringes): Use list3.
3545 (Fwindow_scroll_bars): Use list4.
3546 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3547 (Fwindow_combination_limit): Allow zero number of arguments.
3549 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3551 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3553 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3554 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3555 file descriptor 2 for standard error. (Bug#12805)
3557 2012-11-05 Chong Yidong <cyd@gnu.org>
3559 * process.c (wait_reading_process_output): Revert previous change.
3561 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3563 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3564 This removes code that has been obsolete since around 1990.
3565 * callproc.c (Fcall_process):
3567 * process.c (create_process):
3568 * term.c (dissociate_if_controlling_tty):
3569 Assume setsid exists.
3570 * callproc.c (child_setup): Assume setpgid exists and behaves as
3571 per POSIX.1-1988 or later.
3572 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3573 * emacs.c (shut_down_emacs):
3574 * sysdep.c (sys_suspend, init_foreground_group):
3575 Assume getpgrp behaves as per POSIX.1-1998 or later.
3576 * msdos.c (setpgrp): Remove.
3577 (tcgetpgrp, setpgid, setsid): New functions.
3578 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3579 * term.c (no_controlling_tty): Remove; unused.
3580 * w32proc.c (setpgrp): Remove.
3581 (setsid, tcgetpgrp): New functions.
3583 Simplify by assuming __fpending.
3584 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3585 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3586 Do not assume that __fpending's result fits in int.
3588 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3590 Remove EMACS_OUTQSIZE+sleep hack.
3591 * dispnew.c (update_frame_1): Remove hack for terminals slower
3592 than 2400 bps, which throttled Emacs by having it sleep.
3593 This code hasn't worked since at least 2007, when the multi-tty stuff
3594 was added, and anyway those old terminals are long dead.
3595 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3596 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3598 Fix data-loss with --version (Bug#9574).
3599 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3600 as we can't assume that emacs_strerror is initialized, and strerror
3601 is good enough here.
3602 (main): Invoke atexit earlier, to catch earlier instances of
3603 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3605 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3607 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3608 (keyDown): Remap keypad keys to X11 virtual key codes.
3610 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3612 Fix data-loss with --batch (Bug#9574).
3613 * emacs.c: Include <close-stream.h>.
3614 (close_output_streams): New function.
3615 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3616 and handles errors appropriately.
3617 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3620 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3621 The symptom is a diagnostic "GLib-WARNING **: In call to
3622 g_spawn_sync(), exit status of a child process was requested but
3623 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3624 waitpid(), so exit status can't be returned." The diagnostic
3625 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3626 The real bug is a race condition between Emacs and glib: Emacs
3627 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3628 so that glib can't find it. Work around the bug by invoking
3629 waitpid only on subprocesses that Emacs itself creates.
3630 * process.c (create_process, record_child_status_change):
3631 Don't use special value -1 in pid field, as the caller now must
3632 know the pid rather than having the callee infer it.
3633 The inference was sometimes incorrect anyway, due to another race.
3634 (create_process): Set new 'alive' member if child is created.
3635 (process_status_retrieved): New function.
3636 (record_child_status_change): Use it.
3637 Accept negative 1st argument, which means to wait for the
3638 processes that Emacs already knows about. Move special-case code
3639 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3640 processes that have already been waited for, by testing and
3641 clearing new 'alive' member.
3642 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3643 now does this internally.
3644 (handle_child_signal): Let record_child_status_change do all
3645 the work, since we do not want to reap all exited child processes,
3646 only the child processes that Emacs itself created.
3647 * process.h (Lisp_Process): New boolean member 'alive'.
3649 Omit duplicate definitions no longer needed with gcc -g3.
3650 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3651 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3652 Define only as macros. There's no longer any need to also define
3653 these symbols as enums or as constants, since we now assume
3654 gcc -g3 when debugging.
3656 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3658 * lisp.mk: Adjust comments to the fact that term/internal is now
3659 loaded from loadup.el.
3661 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3662 (msdos_fatal_signal): New function.
3663 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3666 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3667 for GCC versions before 4.
3668 (emacs_raise): Define to call msdos_fatal_signal.
3670 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3671 iterator when starting in the middle of a display or overlay
3674 2012-11-03 Chong Yidong <cyd@gnu.org>
3676 * process.c (wait_reading_process_output): Clean up the last
3679 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3681 * process.c (wait_reading_process_output): Avoid a race condition
3682 with SIGIO delivery (Bug#11536).
3684 2012-11-03 Chong Yidong <cyd@gnu.org>
3686 * buffer.c (cursor_type): Untabify docstring.
3688 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3690 * frame.h (struct frame): Drop can_have_scroll_bars member
3691 which is meaningless for a long time. Adjust comments.
3692 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3693 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3695 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>

3720 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3722 Window-related stuff cleanup here and there.
3723 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):

3736 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3738 Remove pad from struct input_event.
3739 * termhooks.h (struct input_event): Remove padding field.
3741 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3742 member is never cons for a long time. Adjust comment.
3743 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3744 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3745 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3746 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3748 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3750 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3752 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3754 Fix crash when using Emacs as commit editor for git (Bug#12697).
3755 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3756 and it is configured in conf_post.h.
3757 (Fcall_process): Don't invoke both setsid and setpgid; the former
3758 is enough, if it exists.
3759 * callproc.c (Fcall_process, child_setup):
3760 * process.c (create_process): Use setpgid.
3761 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3763 * dispnew.c (init_display): Initialize the foreground group
3764 if we are running a tty display.

3775 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3777 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3779 * minibuf.c (read_minibuf): Restore current buffer since
3780 choose_minibuf_frame calling Fset_frame_selected_window may
3781 change it (Bug#12766).

3790 displaying the current buffer, signal an error.
3792 2012-10-29 Daniel Colascione <dancol@dancol.org>
3794 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3795 In preparation for fixing bug#12739, move these functions from
3798 * coding.h, coding.c: ... to here, and compile them only when
3799 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3800 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3802 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3804 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.

3808 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3811 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>

3819 remove last_appdefined_event (Bug#12698).
3821 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3823 * frame.c (x_set_font): Catch internal error.
3825 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3827 Avoid overflow in w32 implementation of interval timers.
3828 When possible, for ITIMER_PROF count only times the main thread
3830 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3831 'volatile ULONGLONG' types. All the other data which was
3832 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3833 (GetThreadTimes_Proc): New typedef.
3834 (w32_get_timer_time): New function, returns a suitable time value
3836 (timer_loop): Enter critical section when accessing ULONGLONG
3837 values of the itimer_data struct, as these accesses are no longer
3838 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3839 Remove unused variable.
3840 (init_timers): Initialize s_pfn_Get_Thread_Times.
3841 (start_timer_thread): Don't assign itimer->caller_thread here.

3848 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3849 mouse movement events if the menu bar is active. This avoids
3850 producing a busy "hour-glass" cursor by Windows if the mouse
3851 pointer is positioned over a tooltip shown for some menu item.
3853 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3855 Don't assume process IDs fit in int.
3856 * emacs.c (shut_down_emacs) [!DOS_NT]:
3857 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3858 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3859 Use pid_t, not int, to store process IDs, as 'int'
3860 is not wide enough on a few platforms (e.g., AIX and IRIX).
3862 2012-10-23 Kenichi Handa <handa@gnu.org>
3864 The following change is to make face-font-rescale-alist work
3865 correctly for non-ASCII fonts.

3885 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3887 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3889 Port to OpenBSD 5.1.
3890 * frame.c (Fmouse_position, Fmouse_pixel_position):
3891 * xdisp.c (produce_stretch_glyph):
3892 Declare local vars only when they're needed.
3893 This is clearer and avoids a warning on OpenBSD about unused vars.

3895 This is safer, and avoids OpenBSD warnings about unused vars.
3896 * keyboard.c (record_menu_key): Remove unnecessary decl.
3897 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3898 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3899 as our definition clashes with OpenBSD's.
3900 * xfaces.c (load_face_colors, check_lface_attrs)
3901 (get_lface_attributes_no_remap, get_lface_attributes)
3902 (lface_fully_specified_p, x_supports_face_attributes_p)
3903 (tty_supports_face_attributes_p, face_fontset, realize_face)
3904 (realize_x_face, realize_tty_face):
3905 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3906 merely Lisp_Object *. This is more informative and avoids
3907 a warning on OpenBSD about accessing beyond an object's size.
3909 2012-10-20 Chong Yidong <cyd@gnu.org>
3911 * lread.c (Fload): Doc fix (Bug#12592).

3937 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3938 (staticpro): If we run out of staticpro slots, die with an
3939 informative error instead of just calling emacs_abort.

4195 (detect_input_pending_run_timers):
4196 * process.c (wait_reading_process_output):
4197 Use unsigned for counter where wraparound-on-overflow is desired,
4198 since unsigned is guaranteed to have that behavior and signed is not.
4199 (read_char): Use ptrdiff_t for string length.
4200 (get_input_pending): Remove first argument, since it was always
4201 the same pointer-to-int (now pointer-to-boolean) &input_pending,
4202 and behave as if it had that value. Return new value of
4203 input_pending. All callers changed.
4204 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4205 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
4207 * keymap.c (push_key_description): Omit last arg, which was always 1.
4208 All callers changed.

4227 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
4228 Don't include termopts.h.
4230 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
4232 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
4234 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4236 * commands.h (immediate_quit): Remove duplicate decl.
4238 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
4240 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
4242 (nsfont_open): Remove setting of Vfonts_in_cache.
4243 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
4245 2012-10-09 Eli Zaretskii <eliz@gnu.org>
4247 * w32fns.c (w32_last_error): Change the return value to DWORD, to
4248 match what GetLastError returns. Explain why the function is
4251 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4252 'is_tooltip_frame', to avoid confusion with its global namesake.
4254 2012-10-08 Daniel Colascione <dancol@dancol.org>
4256 * xdisp.c (start_hourglass): Call w32_note_current_window when
4257 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4258 build that caused Emacs to display the hourglass cursor forever.
4260 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4261 which is broken under remote desktop, calculate the number of
4262 colors available for a display based on the display's number of
4263 planes and number of bits per pixel per plane. (bug#10397).
4265 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4267 * nsfont.m (Vfonts_in_cache): New variable.
4268 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4269 are used. Add cached fonts to Vfonts_in_cache.
4270 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4272 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4274 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4276 (FONT_H): Define after FRAME_H.
4277 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4278 Update dependencies.
4280 * w32term.c: Remove leftover declaration of keyboard_codepage.
4282 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4284 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4285 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4286 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.

4298 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4300 2012-10-08 Daniel Colascione <dancol@dancol.org>
4302 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4303 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4304 accidental message numbering hole. Change other messages to
4307 * w32select.h (HAVE_W32SELECT): Remove.
4309 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4310 w32common.h instead of w32heap.h.

4321 (w32_minor_version, w32_build_number, w32_subtype):
4322 Remove duplicate definitions.
4324 * w32fns.c: Include w32common.h; include w32heap.h only in
4327 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4328 Use `report_file_error' instead of `error' in order to better
4329 inform users of what went wrong. Increase NTGUI_UNICODE file
4330 dialog box file name length to 32k, the maximum allowed by the NT
4333 * w32common.h: New file.
4334 (ROUND_UP, ROUND_DOWN, get_page_size)
4335 (get_allocation_unit, get_processor_type, get_w32_major_version)
4336 (get_w32_minor_version, sysinfo_cache, osinfo_cache)

4338 (OS_NT, os_subtype, cache_system_info): Move here.
4340 * unexw32.c, unexcw.c: Include w32common.h.
4342 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4343 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4344 to call syms_of_w32select.
4346 * cygw32.h: Remove obsolete EXFUN declarations.
4348 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4350 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4351 of w32inevt.o from SOME_MACHINE_OBJECTS.
4353 2012-10-08 Daniel Colascione <dancol@dancol.org>
4355 * image.c: Permanent fix for JPEG compilation issue --- limit
4356 jpeglib `boolean' redefinition to Cygwin builds.
4358 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4360 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4362 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4365 2012-10-08 Daniel Colascione <dancol@dancol.org>
4367 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4368 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,

4371 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4372 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4373 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4374 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4375 now a supported configuration.
4377 * Makefile.in: consolidate image variables into LIBIMAGE; add
4378 W32_OBJ and W32_LIBS. Compile new files.
4381 (_DebPrint) declare tracing facility for W32 debugging. We need
4382 to unify tracing later.
4384 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4385 unconditional use of W32 Unicode functions. Cygwin runs only on
4386 100% Unicode operating systems.
4388 * cygw32.c: New file. Define Cygwin-specific facilities.
4389 (Fcygwin_convert_path_to_windows)
4390 (Fcygwin_convert_path_from_windows): New user functions for
4391 accessing Cygwin path-munging routines.
4393 * cygw32.h: New file.
4394 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4395 UTF-16LE strings temporarily inside non-Lisp-visible string
4398 (w32_strerror): Just what it says on the tin.
4400 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4401 also run for Cygwin; both systems have the same problem with using
4402 GUI facilities in a forked child. Also call syms_of_cygw32,
4403 syms_of_w32select in correct places.
4405 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4406 needs fork-then-exec for daemon launching.
4408 * font.h: Include frame.h.
4410 * image.c: Use the image library cache machinery only when we're
4411 compiling for native WINDOWSNT; Cygwin can use shared libraries
4412 like any other Unixlike system.
4414 * keyboard.c: Clarify a comment regarding the input loop.
4416 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4417 functions directly instead of trying to detect at runtime that our
4418 host operating system supports them. We make this change for two
4419 reasons: Cygwin lacks support for the multibyte character
4420 conversion functions used by the legacy menu code, and Cygwin
4421 never needs to rely on non-Unicode APIs.
4423 * unexw32.c (hinst): Declare extern.
4425 * w32.c: Change header order;
4426 (w32_strerror): Move to w32fns.c because we need it for
4427 non-WINDOWSNT builds.
4429 * w32.h: Add #error macro to make sure we don't include w32.h for
4430 Cygwin builds. Remove w32select declarations.
4432 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4433 w32fns.c. w32console.c is WINDOWSNT-only.
4435 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4436 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4438 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4439 (w32_major_version, w32_minor_version, w32_build_number)
4440 (os_subtype, sound_type): Define here
4441 (w32_defined_color): Make color parameter const for consistency
4442 with other _defined_color functions.
4443 (w32_createwindow): Unconditionally call w32_init_class instead of
4444 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4445 through the code is complex and unnecessary because class
4446 registration is practically free.
4447 (w32_name_of_message): New EMACSDEBUG-only function.
4448 (Fset_message_beep): Move here
4449 (Fx_open_connection): Require that the display name for Windows be
4450 "w32" for consistency, emacsclient disambiguation, and maybe, one
4451 day, multi-window-system support.
4452 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4453 Cygwin files for W32 GUI facilities, since these clearly don't
4454 expect Cygwin names.
4455 (_DebPrint): Define.
4456 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4457 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4458 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4459 (w32_last_error): Remove.
4461 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4463 * w32heap.c (syspage_mask): Declare here.
4464 (cache_system_info): Remove.
4466 * w32inevt.c (faked_key): Define globally, not statically.
4467 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4468 (w32_console_toggle_lock_key): Move to w32fns.c.
4470 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4472 * w32proc.c (_DebPrint): Move to w32fns.c.
4473 * w32select.c: Include string.h, stdio.h for Cygwin.
4474 * w32select.h: New File.
4476 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4478 (w32_message_fd): New variable. Under Cygwin, holds the file
4479 descriptor the system used to tell us about pending thread
4482 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4483 that prevented compilation under non-WINDOWSNT systems.
4485 (w32_initialize): Open /dev/windows and assign it to
4486 w32_message_fd. Provide w32 feature.
4488 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4489 (WM_EMACS_INPUT_READY): add.
4490 (prepend_msg, w32_message_fd): Declare globally.
4493 (keyboard_handle): Use only when WINDOWSNT.
4494 (notify_msg_ready): New function. Posts a message to the main
4495 thread's message queue under CYGWIN, which wakes up the main
4496 thread from select(2) by making the /dev/windows file descriptor
4497 ready. Under WINDOWSNT, it sets an event the same way the old
4500 (post, prepend_msg): Actually call notify_msg_ready instead of
4501 setting the input event directly.
4503 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4505 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4506 but it still has blocs in it, don't return it to the system,
4507 instead of aborting. (Bug#12402)
4509 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4511 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4513 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4514 MAC_OS_X_VERSION_10_6.

4519 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4521 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4522 MAC_OS_X_VERSION_10_4.
4524 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4525 MAC_OS_X_VERSION_10_2.
4527 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4529 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4530 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4532 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4533 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4534 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4535 Remove ns_in_resize check.
4536 (ns_clear_frame_area): Remove resize handle code.
4538 * nsfns.m (ns_in_resize): Remove.
4539 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4540 Remove ns_in_resize check.
4542 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4544 Improve sys_siglist detection.
4545 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4546 defined as a macro, as is done in Solaris.
4547 (sys_siglist_entries): New macro.
4548 (save_strsignal): Use it.
4549 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4550 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4552 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4554 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4555 fullscreen/Fullscreen.
4557 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4558 tobar_height is new.
4560 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4561 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4562 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4563 (windowDidResize:): Check for correct window if old style fullscreen.
4564 Capitalize word in comment. Remove incorrect comment.
4565 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4566 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4567 error in drawing background.
4568 (toggleFullScreen:): Remove comment. Rearrange calls.
4569 Set toolbar values to zero, save old height in tobar_height.
4570 Restore tool bar height when leaving fullscreen.
4571 (canBecomeMainWindow): New function.
4573 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4575 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4577 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4579 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4581 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4582 that time stamps of directories could also be changed.
4583 Don't request the too broad GENERIC_WRITE, only the more restrictive
4584 FILE_WRITE_ATTRIBUTES access rights.
4586 * fileio.c (Fset_file_times): Special-case ignoring errors for
4587 directories only on MSDOS, not on MS-Windows.
4589 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4591 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4593 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4595 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4596 see whether CreateFile failed.
4598 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4600 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4601 to avoid similar races.
4602 * keyboard.c (pending_signals): Now bool, not int.
4604 Port timers to OpenBSD, plus check for timer failures.
4605 OpenBSD problem reported by Han Boetes.
4606 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4608 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4609 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4610 like OpenBSD, which has timer_settime but does not declare it.
4611 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4612 whether to use itimerspec-related primitives. All uses of
4613 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4615 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4617 * profiler.c (handle_profiler_signal): Fix a malloc race
4618 that caused Emacs to hang on Fedora 17 when profiling Lisp.

4624 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4626 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4627 consistent with the change in return value of 'safe_strsignal'.
4629 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4631 Prefer plain 'static' to 'static inline' (Bug#12541).
4632 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4633 (bidi_set_sor_type, bidi_push_embedding_level)
4634 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4635 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4636 (bidi_cache_search, bidi_cache_ensure_space)
4637 (bidi_cache_iterator_state, bidi_cache_find)
4638 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4639 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4640 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4641 Now 'static', not 'static inline'.
4643 Count overruns when profiling; change units to ns.
4644 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4645 Give extra weight to samples after overruns, to attempt to count
4646 the time more accurately.
4647 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4648 the underlying primitives nominally do ns.
4649 (Fprofiler_cpu_start): Document the change. Mention that
4650 the sampling intervals are only approximate.
4652 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4654 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.

4657 case for the special 0 coding-system.
4659 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4660 (Fmake_overlay): Remove redundant tests.
4661 (fix_start_end_in_overlays): Remove redundant recentering.

4666 Update dependencies.
4668 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4670 Fix a malloc race condition involving strsignal.
4671 A signal can arrive in the middle of a malloc, and Emacs's signal
4672 handler can invoke strsignal, which can invoke malloc, which is
4673 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4674 Fix it by altering the signal handler so that it does not invoke
4676 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4677 * process.c (status_message): Use const pointer, in case strsignal
4678 is #defined to safe_strsignal.
4679 * sysdep.c (sys_siglist, init_signals): Always define and
4680 initialize a substitute sys_siglist if the system does not define
4681 one, even if HAVE_STRSIGNAL.
4682 (safe_strsignal): Rename from strsignal. Always define,
4683 using sys_siglist. Return a const pointer.
4684 * syssignal.h (safe_strsignal): New decl.
4685 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4687 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4689 * w32proc.c (timer_loop): Fix code that waits for timer
4690 expiration, to avoid high CPU usage.
4692 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4694 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4695 (sweep_weak_table): Remove redundant prototypes.
4697 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4699 * emacs.c: Move the inclusion of TERM_HEADER after including
4700 windows.h on WINDOWSNT. This avoids compilation problems with
4703 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4705 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4706 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4707 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4708 as the previous version used 'void *'.
4710 * ralloc.c (ROUNDUP): Fix last change.
4711 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4714 * w32proc.c <disable_itimers>: New static flag.
4715 (init_timers): Initialize it to zero, after creating the critical
4716 sections used by the timer threads.
4717 (term_timers): Set to 1 before deleting the critical sections.
4718 (getitimer, setitimer): If disable_itimers is non-zero, return an
4719 error indication without doing anything. Reported by Fabrice
4720 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4721 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4723 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4726 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4727 term_ntproc after all the other bookkeeping, to get timers working
4728 as long as possible.
4730 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4732 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4733 Suggested by Juri Linkov in
4734 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4736 Prefer plain 'static' to 'static inline' (Bug#12541).
4737 With static functions, modern compilers inline pretty well by
4738 themselves; advice from programmers often hurts as much as it helps.
4739 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4740 this change shrinks the text size of the Emacs executable by 1.1%
4741 without affecting CPU significantly in my benchmark.

4822 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4824 Revert the FOLLOW-SYMLINKS change for file-attributes.
4825 Doing it right would require several changes to Tramp, and there's
4826 not enough time to get that tested before the freeze today.
4827 * dired.c (directory_files_internal, Ffile_attributes):
4830 * frame.c (x_report_frame_params): Port better to wider ints.
4831 Do not assume that EMACS_UINT is the same width as uprintmax_t,

4864 * w32.c (init_environment, get_emacs_configuration): Support AMD64
4866 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
4867 compatibility with x64.
4869 * vm-limit.c (lim_data): Now size_t.
4870 (check_memory_limits): Adjust prototypes of real_morecore and
4871 __morecore to receive argument of type ptrdiff_t. Use size_t for
4872 five_percent and data_size.
4874 * unexw32.c: Use DWORD_PTR instead of DWORD for file-scope
4875 variables, for compatibility with x64.

4927 (struct itimer_data): New definition.
4928 (ticks_now, real_itimer, prof_itimer, clocks_min, crit_real)

4957 2012-09-30 Kenichi Handa <handa@gnu.org>
4959 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
4960 to the buffer relocation which may be caused by ccl_driver.

5020 HAVE_TIMER_SETTIME is defined.
5022 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5024 Profiler improvements: more-accurate timers, overflow checks.
5025 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
5026 signal.h, setjmp.h. Include systime.h instead.
5027 (saturated_add): New function.
5028 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.

5034 All uses changed to store the new value.
5035 (handle_profiler_signal): Rename from sigprof_handler_1,
5036 for consistency with other handlers. Do not check whether
5037 cpu_log is a hash-table if garbage collecting, since it
5038 doesn't matter in that case.
5039 (deliver_profiler_signal): Rename from sigprof_handler,
5040 for consistency with other handlers.
5041 (setup_cpu_timer): New function, with much of what used to be in
5042 Fprofiler_cpu_start. Check for out-of-range argument.
5043 Prefer timer_settime if available, and prefer
5044 thread cputime clocks, then process cputime clocks, then
5045 monotonic clocks, to the old realtime clock. Use make_timeval
5046 to round more-correctly when falling back to setitimer.
5047 (Fprofiler_cpu_start): Use it.
5048 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5049 Don't assume that passing NULL as the 2nd argument of setitimer
5050 is the same as passing a pointer to all-zero storage.
5051 Ignore SIGPROF afterwards.
5052 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5053 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5054 non-fatal signal handlers. Ignore SIGPROF on startup.
5055 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5056 in profiler.c, since sysdep.c now uses it.
5058 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

5080 2012-09-28 Eli Zaretskii <eliz@gnu.org>
5082 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
5083 Qautomatic_redisplay and change the symbol name. All users changed.

5095 Check more robustly for timer_settime.
5096 * Makefile.in (LIB_TIMER_TIME): New macro.
5098 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
5099 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
5102 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>

5110 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
5112 * character.h (MAYBE_UNIFY_CHAR): Remove.
5113 * charset.c, charset.h (maybe_unify_char): Now static.
5114 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5115 Since this stuff is now private to charset.c, there's no need for
5116 a public macro and no need to inline by hand.

5119 Stefan Monnier <monnier@iro.umontreal.ca>
5120 Juanma Barranquero <lekktu@gmail.com>

5145 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
5147 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
5149 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
5151 Prefer POSIX timers if available.
5152 They avoid a race if the timer is too close to the current time.
5153 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
5154 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
5155 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
5157 2012-09-25 Eli Zaretskii <eliz@gnu.org>

5166 Move Vlibrary_cache to emacs.c and reset before dumping.
5168 * lisp.h (reset_image_types): Declare.
5169 [WINDOWSNT] (Vlibrary_cache): Declare.
5171 * image.c (reset_image_types): New function.
5173 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

5180 * w32.h (Vlibrary_cache): Do not declare.
5182 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5184 * w32proc.c (sys_signal): Handle all signals defined by the
5185 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5186 handlers for signals supported by Windows. Don't override
5187 term_ntproc as the handler for SIGABRT.
5188 (sigaction): Rewrite to call sys_signal instead of duplicating its
5190 (sys_kill): Improve commentary.
5192 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5193 consistency with a signature of a signal handler. All callers
5195 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5196 install term_ntproc as a signal handler for SIGABRT, as that
5197 should be done by the dumped Emacs.
5199 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5201 * w32select.c (term_w32select): Protect against repeated
5202 invocation by setting clipboard_owner to NULL after calling

5213 2012-09-25 Chong Yidong <cyd@gnu.org>
5215 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
5217 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5219 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5220 when encountering an unknown bytecode.
5222 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5224 image.c, indent.c: Use bool for booleans.
5225 * dispextern.h (struct image_type): Members valid_p, load, init
5226 now return bool, not int. All uses changed.
5227 * image.c: Omit unnecessary static decls.
5228 (x_create_bitmap_mask, x_build_heuristic_mask):
5229 Return void, not int, since callers don't care about the return value.

5260 2012-09-24 Chong Yidong <cyd@gnu.org>
5262 * chartab.c (Fset_char_table_default): Obsolete function removed.
5264 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5266 Move pid_t related decls out of lisp.h.
5267 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5268 (interruptible_wait_for_termination):
5269 Move these decls from lisp.h to syswait.h, since they use pid_t.
5270 Needed on FreeBSD; see Herbert J. Skuhra in
5271 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5272 * callproc.c: Include syswait.h.

5290 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
5291 * xfns.c (Fx_show_tip) [USE_GTK]:
5292 Use bool for boolean.
5293 * gtkutil.c (xg_update_frame_menubar):
5294 * xmenu.c (update_frame_menubar):
5295 Return void, not int, since caller ignores return value.
5296 * gtkutil.c (xg_change_toolbar_position):
5299 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5301 * makefile.w32-in (BLOCKINPUT_H): Remove.

5318 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5320 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5321 fatal_error_backtrace.
5323 * w32proc.c (sys_kill): Undo last change: don't do anything when
5324 invoked to deliver SIGABRT to our own process. This is now
5325 handled by emacs_raise.
5327 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5329 * w32term.c (w32_read_socket): Remove leftover reference to
5330 interrupt_input_pending.
5332 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5334 Do not use SA_NODEFER.
5335 Problem reported by Dani Moncayo in
5336 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5338 * sysdep.c (emacs_abort): Do not reset signal handler.
5339 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5340 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5341 wanted even on POSIXish hosts, and it doesn't work on Windows.
5343 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5345 * xterm.c (x_term_init): Call fixup_locale before and after calling
5346 gtk_init (Bug#12392).
5348 2012-09-23 Chong Yidong <cyd@gnu.org>
5350 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5351 Vdynamic_library_alist.
5353 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5354 (Fgnutls_available_p): Caller changed.
5356 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5357 (Flibxml_parse_xml_region): Likewise.
5359 * dispextern.h (struct image_type): Remove arg from init function.
5361 * image.c (Finit_image_library, lookup_image_type)
5362 (define_image_type): Remove now-unneeded second arg.
5363 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5364 (init_tiff_functions, init_gif_functions, init_svg_functions):
5365 Arglist and w32_delayed_load calling convention changed.
5366 (gs_type): Remove init_gs_functions; there is no such function.
5367 (valid_image_p, make_image): Fix caller to lookup_image_type.
5369 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5371 Simplify and avoid signal-handling races (Bug#12471).
5373 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5374 Avoid recursive loop if there's a fatal error in the function itself.
5375 * atimer.c (pending_atimers):
5376 * blockinput.h: Don't include "atimer.h"; no longer needed.
5377 (interrupt_input_pending): Remove. All uses removed.
5378 pending_signals now counts both atimers and ordinary interrupts.
5379 This is less racy than having three separate pending-signal flags.
5380 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5382 Rename from their upper-case counterparts BLOCK_INPUT,
5383 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5384 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5385 This makes it easier to access volatile variables more accurately.
5386 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5387 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5388 that's more reliable if the code is buggy and sets
5389 interrupt_input_blocked to a negative value. All uses changed.
5390 * atimer.c (deliver_alarm_signal):
5391 Remove. No need to deliver this to the parent; any thread can
5392 handle this signal now. All uses replaced by underlying handler.
5393 * atimer.c (turn_on_atimers):
5394 * dispnew.c (handle_window_change_signal):
5395 * emacs.c (handle_danger_signal):
5396 * keyboard.c (kbd_buffer_get_event):
5397 Don't reestablish signal handler; not needed with sigaction.
5398 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5400 Rework to avoid unnecessary accesses to volatile variables.
5401 (UNBLOCK_INPUT_TO): Now a function.
5402 (totally_unblock_input, unblock_input): New decls.
5403 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5404 (init_data): Remove. Necessary stuff now done in init_signal.
5405 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5406 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5407 (fatal_error_code): Remove; no longer needed.
5408 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5409 it doesn't always backtrace. All uses changed. No need to reset
5410 signal to default, since sigaction and/or die does that for us now.
5411 Use emacs_raise (FOO), not kill (getpid (), FOO).
5412 (main): Check more-accurately whether we're dumping.
5413 Move fatal-error setup to sysdep.c
5414 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5415 * gtkutil.c (xg_get_file_name, xg_get_font):
5416 Remove no-longer-needed signal-mask manipulation.
5417 * keyboard.c, process.c (POLL_FOR_INPUT):
5418 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5419 * keyboard.c (read_avail_input): Remove.
5420 All uses replaced by gobble_input.
5421 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5422 (kbd_buffer_store_event_hold, gobble_input):
5423 (record_asynch_buffer_change) [USABLE_SIGIO]:
5424 (store_user_signal_events):
5425 No need to mess with signal mask.
5426 (gobble_input): If blocking input and there are terminals, simply
5427 set pending_signals to 1 and return. All hooks changed to not
5428 worry about whether input is blocked.
5429 (process_pending_signals): Clear pending_signals before processing
5430 them, in case a signal comes in while we're processing.
5431 By convention callers now test pending_signals before calling us.
5432 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5433 New functions, to support changes to blockinput.h.
5434 (handle_input_available_signal): Now extern.
5435 (reinvoke_input_signal): Remove. All uses replaced by
5437 (quit_count): Now volatile, since a signal handler uses it.
5438 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5439 All callers changed. Block SIGINT only if not already blocked.
5440 Clear sigmask reliably, even if Fsignal returns, which it can.
5441 Omit unnecessary accesses to volatile var.
5442 (quit_throw_to_read_char): No need to restore sigmask.
5443 * keyboard.c (gobble_input, handle_user_signal):
5444 * process.c (wait_reading_process_output):
5445 Call signal-handling code rather than killing ourselves.
5446 * lisp.h: Include <float.h>, for...
5447 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5448 (pending_signals): Now volatile.
5449 (syms_of_data): Now const if IEEE floating point.
5450 (handle_input_available_signal) [USABLE_SIGIO]:
5451 (terminate_due_to_signal, record_child_status_change): New decls.
5452 * process.c (create_process): Avoid disaster if memory is exhausted
5453 while we're processing a vfork, by tightening the critical section
5455 (send_process_frame, process_sent_to, handle_pipe_signal)
5456 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5458 (send_process): No need for setjmp/longjmp any more, since the
5459 SIGPIPE stuff is now gone. Instead, report an error if errno
5461 (record_child_status_change): Now extern. PID and W are now args.
5462 Return void, not bool. All callers changed.
5463 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5464 Remove. All uses removed. This bug should be fixed now in a
5466 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5467 and record the child status change directly. This avoids the
5468 need to futz with the signal mask.
5469 (process_fatal_action): Move here from emacs.c.
5470 (emacs_sigaction_flags): New function, containing
5471 much of what used to be in emacs_sigaction_init.
5472 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5473 caught by emacs, to make races less likely.
5474 (deliver_process_signal): Rename from handle_on_main_thread.
5476 (BACKTRACE_LIMIT_MAX): Now at top level.
5477 (thread_backtrace_buffer, threadback_backtrace_pointers):
5479 (deliver_thread_signal, deliver_fatal_thread_signal):
5480 New functions, for more-accurate delivery of thread-specific signals.
5481 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5482 (deliver_arith_signal): Handle in this thread, not
5483 in the main thread, since it's triggered by this thread.
5484 (maybe_fatal_sig): New function.
5485 (init_signals): New arg DUMPING so that we can be more accurate
5486 about whether we're dumping. Caller changed.
5487 Treat thread-specific signals differently from process-general signals.
5488 Block all signals while handling fatal error; that's safer.
5489 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5491 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5492 Ignore SIGPIPE unless batch.
5493 (emacs_backtrace): Output backtrace for the appropriate thread,
5494 which is not necessarily the main thread.
5495 * syssignal.h: Include <stdbool.h>.
5496 (emacs_raise): New macro.
5497 * xterm.c (x_connection_signal): Remove; no longer needed
5498 now that we use sigaction.
5499 (x_connection_closed): No need to mess with sigmask now.
5500 (x_initialize): No need to reset SIGPIPE handler here, since
5501 init_signals does this for us now.
5503 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5505 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5506 background rect may be larger (Bug#12245).
5508 2012-09-23 Chong Yidong <cyd@gnu.org>
5510 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5512 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5514 * .gdbinit: Just stop at fatal_error_backtrace.
5515 See Stefan Monnier's request in
5516 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5517 Remove no-longer-used query of system type.
5519 2012-09-22 Chong Yidong <cyd@gnu.org>
5521 * search.c (Freplace_match): Doc fix (Bug#12325).
5523 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5525 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5526 (Fline_end_position): Doc fix.
5528 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5530 2012-09-22 Chong Yidong <cyd@gnu.org>
5532 * dispextern.h (struct image_type): Add new slot, storing a type
5533 initialization function.
5535 * image.c (define_image_type): Call the image initializer function
5536 if it is defined. Arguments and return value changed.
5537 (valid_image_p, make_image): Callers changed.
5538 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5539 (gif_type, imagemagick_type, svg_type, gs_type):
5540 Add initialization functions.
5541 (Finit_image_library): Call lookup_image_type.
5542 (CHECK_LIB_AVAILABLE): Macro deleted.
5543 (lookup_image_type): Call define_image_type here, rather than via
5544 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5545 (syms_of_image): Move define_image_type calls for xbm_type and
5546 pbm_type to lookup_image_type.
5548 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5550 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5551 'idle_timers' from here ...
5552 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5553 lists, to avoid infloops when the timer does something stupid,
5554 like reinvoke itself with the same or smaller time-out.
5557 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5559 * window.c (Fsplit_window_internal): Handle only Qt value of
5560 Vwindow_combination_limit separately.
5561 (Qtemp_buffer_resize): New symbol.
5562 (Vwindow_combination_limit): New default value.
5565 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5567 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5568 the new overlay string. (Bug#10159)
5570 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5572 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5573 or that fprintf is async-signal-safe. POSIX doesn't require
5576 2012-09-22 Chong Yidong <cyd@gnu.org>
5578 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5581 2012-09-22 Kenichi Handa <handa@gnu.org>
5583 * composite.c (composition_reseat_it): Handle the case that a
5584 grapheme cluster is not covered by a single font (Bug#12352).
5586 2012-09-21 Chong Yidong <cyd@gnu.org>
5588 * image.c (define_image_type): Avoid adding duplicate types to
5589 image_types (Bug#12463). Suggested by Jörg Walter.
5591 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5593 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5594 (print_load_command_name): Add case LC_DATA_IN_CODE.
5595 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5597 2012-09-21 Glenn Morris <rgm@gnu.org>
5599 * eval.c (Frun_hook_with_args_until_success)
5600 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5602 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5604 * fileio.c (Ffile_selinux_context): Only call freecon when
5605 lgetfilecon succeeded.
5606 (Fset_file_selinux_context): Likewise. (Bug#12444)
5608 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5610 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5611 reordering, locate the cursor by calling set_cursor_from_row; if
5612 that fails, clear the desired glyph matrix before returning a
5613 failure indication to the caller. Fixes leaving garbled display
5614 when fast scrolling with a down-key. (Bug#12403)
5615 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5616 scrolling through multibyte text.
5618 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5620 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5621 calling mark_vectorlike since that's the one that marks the window.
5622 (mark_discard_killed_buffers): Mark the final cdr.
5623 * window.h (struct window): Move prev/next_buffers to the
5624 non-standard fields.
5625 * window.c (make_window): Initialize prev/next_buffers manually.
5627 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5629 Omit unused arg EXPECTED from socket hooks.
5630 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5631 * nsterm.m (ns_term_init):
5632 * termhooks.h (struct terminal.read_socket_hook):
5633 * w32inevt.c (w32_console_read_socket):
5634 * w32term.c (w32_read_socket):
5635 * xterm.c (XTread_socket):
5636 Omit unused arg EXPECTED. All callers changed.
5637 (store_user_signal_events): Return void, not int, since callers no
5638 longer care about the return value. All uses changed.
5640 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5642 * w32gui.h (XParseGeometry): Do not declare.
5644 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5646 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5647 Ignore 'expected'. See Eli Zaretskii in
5648 <http://bugs.gnu.org/12471#8> (last line).
5650 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5651 (XParseGeometry): Now static. Substitute extremal values for
5652 values that are out of range.
5654 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5656 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5658 * nsfns.m (XParseGeometry): Remove.
5659 (Fx_create_frame): Call x_set_offset to correctly interpret
5660 top_pos in geometry.
5662 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5663 (Fx_parse_geometry): If there is a space in string, call
5664 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5666 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5668 * search.c (scan_buffer): Use character positions in calls to
5669 region_cache_forward and region_cache_backward, not byte
5670 positions. (Bug#12196)
5672 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5673 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5675 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5676 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5677 emacs_blocked_malloc, now deleted.
5679 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5681 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5682 The workaround was for improving performance on Solaris 2.4, but
5683 is getting in the way now. Emacs will still work if someone is
5684 still running Solaris 2.4 in a museum somewhere; Sun dropped
5685 support for Solaris 2.4 in 2003.
5686 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5687 * process.c (create_process) [HAVE_WORKING_VFORK]:
5688 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5689 since Emacs no longer uses vfork on that platform.
5691 2012-09-17 Glenn Morris <rgm@gnu.org>
5693 * emacs.c: Use COPYRIGHT.
5695 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5697 Remove configure's --without-sync-input option (Bug#12450).
5698 When auditing signal-handling in preparation for cleaning it up,
5699 I found that SYNC_INPUT has race conditions and would be a real
5700 pain to fix. Since it's an undocumented and deprecated
5701 configure-time option, now seems like a good time to remove it.
5702 Also see <http://bugs.gnu.org/11080#16>.
5703 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5704 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5705 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5706 (malloc_hysteresis):
5707 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5708 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5709 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5710 (dont_register_blocks, bytes_used_when_reconsidered)
5711 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5712 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5713 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5714 Remove. All uses removed.
5715 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5716 implementation, one that depends on whether the new macro
5717 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5719 * atimer.c (run_timers, handle_alarm_signal):
5720 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5721 (handle_async_input, process_pending_signals)
5722 (handle_input_available_signal, init_keyboard):
5723 * nsterm.m (ns_read_socket):
5724 * process.c (wait_reading_process_output):
5725 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5726 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5728 * xterm.c (XTread_socket):
5730 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5731 * eval.c (handling_signal): Remove. All uses removed.
5732 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5733 All uses replaced with the SYNC_INPUT version.
5734 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5736 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5739 * font.c (Ffont_shape_gstring): Remove unused local.
5741 2012-09-16 Glenn Morris <rgm@gnu.org>
5743 * Makefile.in (clean): No longer run nextstep's clean.
5745 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5747 (ns-app): Move here from ns.mk, and simplify.
5748 (clean): Simplify nextstep entry.
5749 * ns.mk: Remove file.
5751 2012-09-17 Kenichi Handa <handa@gnu.org>
5753 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5754 not covert the last few charactes.
5756 2012-09-16 Kenichi Handa <handa@gnu.org>
5758 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5759 here, but just check the validity of glyphs in the glyph-string.
5761 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5763 * window.c (Fwindow_parameter, Fset_window_parameter):
5764 Accept any window as argument (Bug#12452).
5766 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5768 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5769 to ns_term_init to avoid memory leak.
5771 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5772 explicit retain/release.
5773 (ns_term_init): Only allow one display. Initialize outerpool and
5776 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5778 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5779 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5780 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5781 the Microsoft problem in a different way, by altering ../nt/config.nt.
5783 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5798 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5799 by lisp.h. This completes removal of setjmp.h inclusion
5800 erroneously announced in the previous commit. (Bug#12446)
5802 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5805 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5806 not defined as a macro. The latter happens on MS-Windows.
5809 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5811 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5812 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5813 Some instances of '#include <setjmp.h>' removed, if the
5814 only reason for the instance was because "lisp.h" was included.
5815 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5816 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5817 and _longjmp with the new symbols. Emacs already uses _setjmp if
5818 available, so this change affects only POSIXish hosts that have
5819 sigsetjmp but not _setjmp, such as some versions of Solaris and
5820 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5821 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5822 (png_load_body) [HAVE_PNG]:
5823 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5824 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5825 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5826 since PNG requires jmp_buf. This is the only exception to the
5827 general rule that we now use sys_setjmp and sys_longjmp.
5828 This exception is OK since this code does not change the signal
5829 mask or longjmp out of a signal handler.
5831 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5833 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5834 Include "syssignal.h", for 'main_thread'.
5836 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5838 Avoid out-of-range marker position (Bug#12426).
5839 * insdel.c (replace_range, replace_range_2):
5840 Adjust markers before overlays, as suggested by comments.
5841 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5842 Remove redundant check before calling offset_intervals.
5844 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5846 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5847 current buffer (Bug#12387).
5849 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5851 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5853 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5855 Use a more backwards-compatible timer format (Bug#12430).
5856 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5857 vector element, not from the 4th, since PSECS is now at the end.
5858 (Fcurrent_idle_time): Doc fix.
5860 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5862 Function to mark objects and remove killed buffers at once.
5863 * alloc.c (discard_killed_buffers): Rename to ...
5864 (mark_discard_killed buffers) ... new name. Add marking
5865 of remaining objects. Fix comment. Adjust users.
5866 (mark_object): Do not touch frame buffer lists here.
5867 * frame.c (delete_frame): Reset frame buffer lists here.
5869 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5871 Better workaround for GNOME bug when --enable-gcc-warnings.
5872 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5873 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5874 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5876 Simplify SIGIO usage (Bug#12408).
5877 The code that dealt with SIGIO was crufty and confusing, e.g., it
5878 played tricks like "#undef SIGIO" but these tricks were not used
5879 consistently. Simplify mostly by not #undeffing standard symbols,
5880 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5881 or not as we please) rather than "defined SIGIO" (standard symbol
5882 that we probably shouldn't #undef).
5883 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5884 Modules that need it can include it.
5885 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5886 * dispextern.h (ignore_sigio): New decl.
5887 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5888 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5889 * emacs.c (shut_down_emacs):
5890 * keyboard.c (kbd_buffer_store_event_hold):
5891 Use ignore_sigio rather than invoking 'signal' directly.
5892 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5894 (FIONREAD, SIGIO): Do not #undef.
5895 (tty_read_avail_input): Use #error rather than a syntax error.
5896 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5897 for I_PIPE, used by SETUP_SLAVE_PTY.
5898 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5899 * sysdep.c (croak): Remove; no longer needed. This bit of
5900 temporary code, with Fred N. Fish's comment that it's temporary,
5901 has been in Emacs since at least 1992!
5902 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5903 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5904 * syssignal.h (croak): Remove decl.
5905 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5906 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5907 now that we're termios-only.
5908 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5909 * term.c (dissociate_if_controlling_tty): Use #error rather than
5912 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5913 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5914 to work around GNOME bug 683906.
5915 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5916 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5917 This works around GCC bug 54561.
5919 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5921 More fixes for 'volatile' and setjmp/longjmp.
5922 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5923 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5924 (png_load_body) [HAVE_PNG]:
5925 (jpeg_load_body) [HAVE_JPEG]:
5926 New function, with most of the old parent function's body.
5927 (png_load) [HAVE_PNG]:
5928 (jpeg_load) [HAVE_JPEG]:
5929 Invoke the new function, to avoid longjmp munging our locals.
5930 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5931 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5932 longjmp is passed 2, as the C standard doesn't guarantee this.
5933 Instead, store the failure code into mgr->failure_code.
5935 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5937 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5938 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5939 (syms_of_keyboard): Remove support for unread-command-char.
5941 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5943 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5944 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5945 violation. (Bug#12426)
5947 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5949 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5951 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5953 * eval.c: Add `inhibit-debugger'.
5954 (Qinhibit_debugger): New symbol.
5955 (call_debugger): Bind it instead of Qdebug_on_error.
5956 (maybe_call_debugger): Test Vinhibit_debugger.
5957 (syms_of_eval): Define inhibit-debugger.
5958 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5959 (syms_of_xdisp): Remove inhibit-debug-on-message.
5961 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5963 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5964 If a nonvolatile local variable is written before a _longjmp to
5965 the frame containing the variable, and is read after the _longjmp,
5966 the value read is indeterminate. Some local variables of type
5967 'struct handler' and 'struct catchtag' are used in this way, so
5968 mark each of their slots as volatile if the slot can be set before
5969 _longjmp and read afterwards.
5970 * lisp.h (struct handler): var and chosen_clause are now volatile.
5971 (struct catchtag): val, next, and pdlcount are now volatile.
5973 * bidi.c (bidi_push_it, bidi_pop_it):
5974 * fns.c (copy_hash_table):
5975 * image.c (define_image_type):
5976 * keyboard.c (kbd_buffer_store_event_hold):
5977 * process.c (Fprocess_send_eof):
5978 * xfaces.c (x_create_gc) [HAVE_NS]:
5979 * xgselect.c (xg_select):
5980 Prefer assignment to memcpy when either will do.
5982 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5983 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5984 time an item is removed. No need to mark this function 'inline';
5985 the compiler knows better than we do.
5987 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5989 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5990 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5991 to change_frame_size (Bug#12388).
5992 (windowDidResize:): Pass YES to updateFrameSize.
5994 * nsterm.h: Add delay parameter to updateFrameSize.
5996 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5998 Discard killed buffers from deleted window and frame objects.
5999 This reduces an amount of references to killed buffers and
6000 helps GC to reclaim them faster.
6001 * alloc.c (discard_killed_buffers): New function.
6002 (mark_object): Use it for deleted windows and frames.
6003 (mark_object): If symbol's value is set up for a killed buffer
6004 or deleted frame, restore its global binding.
6005 * data.c (swap_in_global_binding): Add GC notice.
6006 (swap_in_symval_forwarding): Use convenient set_blv_where.
6007 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6008 * window.h: ... to here.
6010 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6012 Convenient macro to check whether the buffer is live.
6013 * buffer.h (BUFFER_LIVE_P): New macro.
6014 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6015 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6017 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6019 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6020 composition cases (Bug#12364).
6022 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6023 overhang of succeeding glyphs overlapping box cursor.
6025 * w32term.c (x_draw_glyph_string): Likewise.
6027 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6029 Simplify, document, and port floating-point (Bug#12381).
6030 The porting part of this patch fixes bugs on non-IEEE platforms
6031 with frexp, ldexp, logb.
6032 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6034 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6035 support, by removing commented-out code and briefly listing the
6036 C89 functions excluded. The commented-out stuff was confusing
6037 maintenance, e.g., we thought we needed cbrt but it was commented out.
6038 (logb): Remove decl; no longer needed.
6039 (isfinite): New macro, if not already supplied.
6040 (isnan): Don't replace any existing macro.
6041 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6042 are present on all C89 platforms.
6043 (Ffrexp): Do not special-case zero, as frexp does the right thing
6045 (Flogb): Do not use logb, as it doesn't have the desired meaning
6046 on hosts that use non-base-2 floating point. Instead, stick with
6047 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6048 frexp, to avoid getting an unspecified result.
6050 * xdisp.c (Qinhibit_debug_on_message): Now static.
6052 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6054 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6055 NSBezierPath (Bug#12131).
6057 2012-09-10 Chong Yidong <cyd@gnu.org>
6059 * fns.c (Fdelq, Fdelete): Doc fix.
6061 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6063 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6064 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6066 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6068 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6069 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6072 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6074 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6075 left fringe if the window has a left margin. This avoids leaving
6076 traces of the cursor because its leftmost pixel is not drawn over.
6078 * dispnew.c (update_window_line): When the left margin area of a
6079 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6080 that screen line. (Bug#12277)
6082 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6084 Assume C89 or later for math functions (Bug#12381).
6085 This simplifies the code, and makes it a bit smaller and faster,
6086 and (most important) makes it easier to clean up signal handling
6087 since we can stop worring about floating-point exceptions in
6088 library code. That was a problem before C89, but the problem
6089 went away many years ago on all practical Emacs targets.
6090 * data.c, image.c, lread.c, print.c:
6091 Don't include <math.h>; no longer needed.
6092 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6093 might be autoconfigured, as that never happens.
6095 * doprnt.c (DBL_MAX_10_EXP):
6096 * print.c (DBL_DIG):
6097 Remove. C89 or later always defines these.
6098 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6099 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6100 (arith_error, domain_error, domain_error2):
6101 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6102 no longer needed -- we simply return what C returns. All uses removed.
6103 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6105 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6106 Remove. All uses expanded, as these macros are no longer used
6107 more than once and are now more trouble than they're worth.
6108 (Ftan): Use tan, not sin / cos.
6109 (Flogb): Assume C89 frexp.
6110 (fmod_float): Assume C89 fmod.
6111 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6112 (init_floatfns): Remove. All uses removed.
6114 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6116 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6117 compositeToPoint for OSX < 10.6 (Bug#12390).
6119 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6121 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6122 This produces more-accurate results.
6124 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6126 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6127 changes (Bug#12088).
6129 2012-09-08 Chong Yidong <cyd@gnu.org>
6131 * syntax.c (Fstring_to_syntax): Doc fix.
6133 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6135 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6136 in the internal border.
6137 (x_set_window_size): Remove static variables and their usage.
6138 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6139 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6140 Remove fringe/internal border adjustment (Bug#11052).
6141 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6142 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6143 (ns_fix_rect_ibw): Remove.
6144 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6145 (ns_dumpglyphs_box_or_relief): Ditto.
6146 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6148 (ns_dumpglyphs_image): Ditto.
6149 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6151 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6152 their usage. Add fringe_extended_p and its use as in other terms.
6153 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6154 scroll bar was removed.
6155 (updateFrameSize): New function.
6156 (windowDidResize): Move code to updateFrameSize and call it.
6158 * nsterm.h (EmacsView): Add updateFrameSize.
6160 2012-09-07 Chong Yidong <cyd@gnu.org>
6162 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6164 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6166 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6168 More signal-handler cleanup (Bug#12327).
6169 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6170 Problem introduced when merging patches. Noted by Eli Zaretskii in
6171 <http://bugs.gnu.org/12327#67>.
6172 * floatfns.c: Comment fix.
6173 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6174 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6175 and anyway the declaration is harmless even if SIGDANGER is not defined.
6176 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6177 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6178 source files not surprisingly expected syssignal.h to define, or
6179 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6180 Include <sys/ioctl.h>, for FIONREAD.
6181 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6182 This eliminates a problem whereby other files mysteriously had
6183 to include "syssignal.h" before including "systty.h" if they
6184 wanted to use "#ifdef SIGIO".
6186 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6188 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6190 * w32.c (sigemptyset): Empty the set.
6191 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6193 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6195 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6197 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6198 (mark_object): Likewise for frame objects.
6200 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6202 * syssignal.h (handle_on_main_thread): Always declare,
6203 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6204 This ports to platforms without HAVE_PTHREAD.
6206 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6208 Signal-handler cleanup (Bug#12327).
6209 Emacs's signal handlers were written in the old 4.2BSD style with
6210 sigblock and sigmask and so forth, and this led to some
6211 inefficiencies and confusion. Rewrite these to use
6212 pthread_sigmask etc. without copying signal sets around. Also,
6213 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6214 'signal', and instead use functions that do not attempt to take
6215 over the system name space. This patch causes Emacs's text
6216 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6217 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6218 Do not include <signal.h> or "syssignal.h", as these
6219 modules do not use signals.
6220 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6221 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6222 Do not include <signal.h>, as "syssignal.h" does that for us now.
6223 * atimer.c (sigmask_atimers): New function.
6224 (block_atimers, unblock_atimers): New functions,
6225 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6227 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6228 no longer needed here.
6229 * emacs.c (main): Inspect existing signal handler with sigaction,
6230 so that there's no need to block and unblock SIGHUP.
6231 * sysdep.c (struct save_signal): New member 'action', replacing
6232 old member 'handler'.
6233 (save_signal_handlers, restore_signal_handlers):
6234 Use sigaction instead of 'signal' to save and restore.
6235 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6236 New function. All users of 'signal' modified to use set_sighandler
6237 if they're writeonly, and to use sys_signal if they're read+write.
6238 (emacs_sigaction_init, forwarded_signal): New functions.
6239 (sys_signal): Remove. All uses replaced by calls to sigaction
6240 and emacs_sigaction_init, or by direct calls to 'signal'.
6241 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6242 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6243 all uses replaced by pthread_sigmask etc. calls.
6244 * syssignal.h: Include <signal.h>.
6245 (emacs_sigaction_init, forwarded_signal): New decls.
6246 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6247 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6248 (sigmask, sys_sigmask): Remove; no longer needed.
6249 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6250 (sigblock, sigunblock, sigfree):
6251 (sigsetmask) [!defined sigsetmask]:
6252 Remove. All uses replaced by pthread_sigmask.
6253 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6254 no longer need to be replaced, and its typical old uses
6255 are now done via emacs_sigaction_init and sigaction.
6256 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6257 (sys_sigdel): Remove; unused.
6258 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6260 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6262 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6263 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6265 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6267 Explicitly mark buffer_defaults and buffer_local_symbols.
6268 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6269 mark_local_symbols here.
6270 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6271 since special buffers aren't marked here any more.
6272 (allocate_buffer): Chain new buffer with all_buffers here...
6273 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6275 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6276 (syms_of_buffer): Remove staticpro of the above.
6277 (init_buffer_once): Set names for buffer_defaults and
6278 buffer_local_symbols.
6280 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6282 Use bool for booleans in font-related modules.
6283 * font.c (font_intern_prop, font_style_to_value)
6284 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6285 (generate_otf_features, font_check_otf_features, font_check_otf)
6286 (font_match_p, font_list_entities, font_at):
6287 * fontset.c (fontset_id_valid_p, reorder_font_vector
6288 (fontset_find_font, Fset_fontset_font)
6289 (face_suitable_for_char_p) [0]:
6290 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6291 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6292 (m17n_flt_initialized, ftfont_shape_by_flt):
6293 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6294 * nsfont.m (nsfont_draw):
6295 * w32font.c (w32font_draw):
6296 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6297 Use bool for booleans.
6298 * font.h: Adjust to above API changes.
6299 (struct font, struct font_driver, struct font_driver_list):
6300 Use bool for booleans.
6301 (struct font): Remove useless member encoding_type.
6303 * fontset.c, xftfont.c: Omit unnecessary static decls.
6305 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6307 * alloc.c (mark_object): Revert window marking code
6308 since it's unsafe for the Fset_window_configuration.
6310 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6312 Fix race conditions with signal handlers and errno (Bug#12327).
6313 Be more systematic about preserving errno whenever a signal
6314 handler returns, even if it's not in the main thread. Do this by
6315 renaming signal handlers to distinguish between signal delivery
6316 and signal handling. All uses changed.
6317 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6318 * data.c (deliver_arith_signal): Rename from arith_error.
6319 * dispnew.c (deliver_window_change_signal): Rename from
6320 window_change_signal.
6321 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6322 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6323 * keyboard.c (deliver_input_available_signal): Rename from
6324 input_available_signal.
6325 (deliver_user_signal): Rename from handle_user_signal.
6326 (deliver_interrupt_signal): Rename from interrupt_signal.
6327 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6328 (deliver_child_signal): Rename from sigchld_handler.
6329 * atimer.c (handle_alarm_signal):
6330 * data.c (handle_arith_signal):
6331 * dispnew.c (handle_window_change_signal):
6332 * emacs.c (handle_fatal_signal, handle_danger_signal):
6333 * keyboard.c (handle_input_available_signal):
6334 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6335 * process.c (handle_pipe_signal, handle_child_signal):
6336 New functions, with the actual signal-handling code taken from the
6337 original respective signal handlers, sans the sporadic attempts to
6338 preserve errno, since that's now done by handle_on_main_thread.
6339 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6340 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6341 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6343 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6344 Move initialization of main_thread to sysdep.c's init_signals.
6345 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6346 our usage, and simplifies the mainline code.
6347 (record_child_status_change): New static function, as a helper
6348 for handle_child_signal, and with most of the old child handler's
6350 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6351 (handle_child_signal): Use the above.
6352 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6353 Moved here from emacs.c.
6354 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6355 code moved here from emacs.c's main function.
6356 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6357 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6358 This lets callers save and restore errno properly.
6360 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6362 Remove redundant or unused things here and there.
6363 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6364 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6365 * editfns.c (Fcompare_buffer_substrings): Likewise.
6366 * frame.h (struct terminal, struct font_driver_list):
6367 Remove redundant declarations.
6368 * window.h (Qleft, Qright): Likewise.
6370 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6372 Do not mark objects from deleted buffers, windows and frames.
6373 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6374 (mark_object): Likewise for windows and frames.
6376 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6378 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6379 buffer_defaults and buffer_local_symbols as valid objects.
6380 Return special value to denote them.
6382 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6384 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6385 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6386 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6387 (file_name_absolute_p, Fsubstitute_in_file_name):

6390 (Finsert_file_contents, choose_write_coding_system)
6391 (Fwrite_region, build_annotations, a_write, e_write)
6393 * filelock.c (boot_time_initialized, get_boot_time)
6394 (get_boot_time_1, lock_file_1, within_one_second):
6395 * floatfns.c (in_float):
6396 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6397 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6398 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6399 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6400 * window.c (compare_window_configurations):
6401 Use bool for booleans.
6402 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6403 (Fdefault_file_modes): Now mode_t, not int, for modes.
6404 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6405 (internal_delete_file): Now returns void, not a (boolean) int,
6406 since nobody was looking at the return value.
6407 * lisp.h, window.h: Adjust to above API changes.
6409 * xdisp.c (set_message): Simplify and reindent last change.
6411 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6413 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6415 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6417 * eval.c (call_debugger): Make the function non-static so that we
6418 can call it from set_message.
6420 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6421 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6423 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6425 Give more-useful info on a fatal error (Bug#12328).
6426 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6427 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6428 of doing the work ourselves.
6429 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6430 do most of the work.
6431 (fatal_error_backtrace): New function, taken from the guts
6432 of the old fatal_error_signal, but with a new option to output
6434 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6435 info about the signal than just its number.
6436 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6437 * sysdep.c: Include <execinfo.h>
6438 (emacs_backtrace): New function, taken partly from the previous
6439 code of the 'die' function.
6440 (emacs_abort): Call fatal_error_backtrace rather than abort.
6442 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6444 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6445 eager (load-time) macro-expansion.
6446 * lisp.mk (lisp): Add macroexp.
6448 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6450 Simplify redefinition of 'abort' (Bug#12316).
6451 Do not try to redefine the 'abort' function. Instead, redo
6452 the code so that it calls 'emacs_abort' rather than 'abort'.
6453 This removes the need for the NO_ABORT configure-time macro
6454 and makes it easier to change the abort code to do a backtrace.
6455 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6456 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6457 Remove; sysdep.c's emacs_abort now takes its place.
6458 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6459 'abort' changed to use 'emacs_abort'.
6460 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6461 (abort) [!defined abort]: Rename to ...
6462 (emacs_abort): ... new name.
6463 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6464 the place of the old 'abort' in emacs.c.
6465 * w32.c, w32fns.c (abort): Do not #undef.
6466 * w32.c (emacs_abort): Rename from w32_abort.
6468 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6470 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6471 offsets[j].dv, since the y axis of the screen coordinates points
6472 down, while the y axis of the font definition coordinates points
6473 up. This fixes display of Arabic diacritics such as KASRA and
6474 KASRATAN. (Bug#11860)
6476 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6478 Be more systematic about _setjmp vs setjmp.
6479 * alloc.c (test_setjmp, mark_stack):
6480 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6481 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6482 (png_load, my_error_exit, jpeg_load):
6483 * process.c (send_process_trap, send_process):
6484 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6485 The underscored versions are up to 30x faster on some hosts.
6486 Formerly, the code used setjmp+longjmp sometimes and
6487 _setjmp+_longjmp at other times, with no particular reason to
6488 prefer setjmp+longjmp.
6490 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6492 Fix minor problem found by static checking.
6493 * buffer.c (Fdelete_all_overlays): Return nil.
6495 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6497 * buffer.c (Fdelete_all_overlays): New function.
6499 2012-09-03 Chong Yidong <cyd@gnu.org>
6501 * gtkutil.c: Add extern decl for Qxft.
6503 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

6518 * eval.c (interactive_p): Omit always-true boolean argument
6519 EXCLUDE_SUBRS_P. All callers changed.
6520 * dispextern.h, lisp.h: Reflect above API changes.
6521 * firstfile.c (dummy): Use the address of 'main', whose signature
6522 won't change, instead of the address of 'initialize', whose
6523 signature just changed from int to bool.
6524 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6525 * msdos.c (fatal_error_in_progress): ... from here.
6526 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6528 (redisplay_internal, unwind_redisplay): Simply clear
6529 REDISPLAYING_P when unwinding, instead of saving its previous,
6530 always-false value and then restoring it.
6532 Clean up some extern decls.
6533 Mostly, this hoists extern decls out of .c files and into .h files.
6534 That way, we're more likely to catch errors if the interfaces change.
6535 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6536 declare xg_mark_data.
6537 * dispextern.h (x_frame_parm_handlers):
6539 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

6553 * widget.c (free_frame_faces):
6554 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
6555 * xfont.c (x_clear_errors):
6556 * xterm.c (x_frame_parm_handlers):
6557 Remove now-redundant extern decls.
6558 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6559 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6561 * xfaces.c: Remove unnecessary static decls.
6562 * xterm.c (updating_frame): Remove decl of nonexistent object.
6564 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6565 when building globals.h, as the objects that are not built on
6566 this host are not needed to compile C files on this host.
6568 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6570 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

6584 (make_buffer_string, make_buffer_string_both)
6585 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

6597 (set_intervals_multibyte_1, set_intervals_multibyte):
6598 * keyboard.c (decode_timer):
6599 Use bool for boolean.
6600 * intervals.h, lisp.h, systime.h: Reflect above API changes.
6601 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.

6608 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
6610 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
6611 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

6618 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6620 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6621 more than one grapheme cluster passed to the shaper: compute the
6622 offset adjustment values separately for each cluster. (Bug#11860)
6624 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6625 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6626 about implicit conversions from integer to pointer.
6628 2012-09-01 Daniel Colascione <dancol@dancol.org>
6630 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6631 system used too early.
6633 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
6635 Better seed support for (random).

6676 * keyboard.c: Include TERM_HEADER instead of listing all possible
6677 window-system headers.
6679 * image.c: Include TERM_HEADER instead of listing all possible

6683 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
6684 window system declarations.
6686 * frame.h: Move common functions here: set_frame_menubar,
6687 x_set_window_size, x_sync, x_get_focus_frame,
6688 x_set_mouse_position, x_set_mouse_pixel_position,
6689 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6713 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6715 Remove mark_ttys function and fix tty_display_info initialization.
6716 * lisp.h (mark_ttys): Remove prototype.
6717 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
6718 to mark_ttys because all possible values of 'top_frame' slot are
6719 the frames which are reachable from Vframe_list.
6720 * term.c (mark_ttys): Remove.
6721 (init_tty): Safely initialize 'top_frame' slot with Qnil.
6723 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

6729 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
6730 bitfields from unsigned char to unsigned.

6745 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6746 for GCC 4.7.1 x86-64.
6748 2012-08-30 Glenn Morris <rgm@gnu.org>
6750 * lread.c (init_lread): For out-of-tree builds, only add the
6751 source directory's site-lisp dir to the load-path if it exists,
6752 consistent with in-tree builds. (Bug#12302)
6754 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
6756 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

6766 (addSplit): Remove return self, declare return value as void.
6767 (clicked:): Remove return self, declare return value as void.
6768 Set dialog_return to button_values[seltag]. Code formatting change.

6770 Code formatting change.
6771 (timeout_handler:): Set timer_fired to YES.
6772 (runDialogAt:): Set timer_fired to NO.
6773 Handle click on close button as quit.
6775 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6776 Add window_closed and button_values. Add void as return value for
6777 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6778 Add process_dialog as new member.
6780 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6782 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

6850 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
6851 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
6852 * dired.c (file_name_completion):
6853 Use bool for boolean. (This was missed in an earlier change.)
6855 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6857 * window.c (Fset_window_configuration): Revert first part of
6860 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
6862 * nsterm.h (NSPanel): New class variable dialog_return.
6864 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
6865 Initialize dialog_return.
6866 (windowShouldClose:): Use stop instead of stopModalWithCode.
6867 (clicked:): Ditto, and also set dialog_return (Bug#12258).
6868 (timeout_handler:): Use stop instead of abortModal. Send a dummy
6870 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
6873 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
6875 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.
6876 * composite.c (find_composition, composition_gstring_p)
6877 (composition_reseat_it, find_automatic_composition):
6878 * data.c (let_shadows_buffer_binding_p)
6879 (let_shadows_global_binding_p, set_internal, make_blv)
6880 (Fmake_variable_buffer_local, Fmake_local_variable)
6881 (Fmake_variable_frame_local, arithcompare, cons_to_unsigned)
6882 (cons_to_signed, arith_driver):
6883 * dbusbind.c (xd_in_read_queued_messages):
6884 * dired.c (directory_files_internal, file_name_completion):
6885 Use bool for booleans.
6886 * dired.c (file_name_completion):
6887 * process.h (fd_callback):
6888 Omit int (actually boolean) argument. It wasn't being used.
6890 * composite.h, lisp.h: Reflect above API changes.
6892 * cmds.c, coding.c: Use bool for booleans.
6893 * cmds.c (move_point, Fself_insert_command):
6894 * coding.h (struct composition status, struct coding_system):

6911 (Funencodable_char_position, code_convert_region)
6912 (code_convert_string, code_convert_string_norecord)
6913 (Fset_coding_system_priority):
6914 * fileio.c (Finsert_file_contents):
6915 Use bool for booleans.
6916 * coding.h, lisp.h: Reflect above API changes.
6917 * coding.c: Remove unnecessary static function decls.
6918 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6919 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6920 not a boolean 'int', since callers never look at the return value.
6921 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
6922 * coding.h (decoding_buffer_size, encoding_buffer_size)
6923 (emacs_mule_string_char): Remove unused extern decls.
6924 (struct iso_2022_spec, struct coding_system):
6925 Use 'unsigned int : 1' for boolean fields, since there's more than one.
6926 (struct emacs_mule_spec): Remove unused field 'full_support'.
6927 All initializations removed.
6928 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
6930 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6932 Fix spare memory change (Bug#12286).
6933 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
6934 (valid_lisp_object_p): Likewise.
6936 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6938 * window.c (Fset_window_configuration): Record any window's old
6939 buffer if it's replaced (see Bug#8789). If the new current
6940 buffer doesn't appear in the selected window, go to its old
6943 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6945 Special MEM_TYPE_SPARE to denote reserved memory.
6946 * alloc.c (enum mem_type): New memory type.
6947 (refill_memory_reserve): Use new type for spare memory.
6948 This prevents live_cons_p and live_string_p from incorrect
6949 detection of uninitialized objects from spare memory as live.
6951 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6954 * Makefile.in (.PHONY): versioclean -> versionclean.
6956 Remove unused external symbols.
6957 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6958 * window.c (Qwindow_valid_p, decode_valid_window):
6959 Now static, not extern.
6960 * data.c (Qinterval): Remove; unused.
6961 (syms_of_data): Do not define 'interval'.
6962 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6963 * window.h (decode_valid_window):
6966 * character.c, charset.c, chartab.c: Use bool for booleans.
6967 * character.c (lisp_string_width, string_count_byte8)
6968 (string_escape_byte8):
6969 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6970 (load_charset_map_from_file, map_charset_chars)
6971 (Fdefine_charset_internal, define_charset_internal)
6972 (Fdeclare_equiv_charset, find_charsets_in_text)
6973 (Ffind_charset_region, char_charset, Fiso_charset):
6974 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
6975 (sub_char_table_set, sub_char_table_set_range)
6976 (char_table_set_range, optimize_sub_char_table)
6977 (map_sub_char_table):
6978 Use bool for boolean.
6979 * character.c (str_to_unibyte): Omit last boolean argument; it was
6980 always 0. All callers changed.
6981 * character.h, charset.h: Adjust to match previous changes.
6982 * character.h (char_printable_p): Remove decl of nonexistent function.
6983 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6984 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6985 are all boolean, so make them single-bit bitfields.
6987 * lisp.h (ASET): Remove attempt to detect side effects.
6988 It was meant to be temporary and it often doesn't work,
6989 because when IDX has side effects the behavior of IDX==IDX
6990 is undefined. See Stefan Monnier in
6991 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6993 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6995 * lisp.h (functionp): New function (extracted from Ffunctionp).
6996 (FUNCTIONP): Use it.
6997 * eval.c (Ffunctionp): Use it.
6999 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7001 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7002 as that's faster and simpler than static storage. Don't bother
7003 with the g_main_context_query overhead if g_main_context_pending
7004 says no events are pending.
7005 (gfds, gfds_size): Remove these static vars.
7006 (xgselect_initialize): Remove; no longer needed.
7007 All uses and decls removed.
7009 * emacs.c (fatal_error_signal_hook): Remove.
7010 All uses removed. This leftover from old code was always 0.
7012 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7013 * casefiddle.c (casify_object, casify_region):
7014 * casetab.c (set_case_table):
7015 * category.c, category.h (word_boundary_p):
7016 * category.h (CHAR_HAS_CATEGORY):
7017 Use bool for booleans, instead of int.
7019 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7021 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7023 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7025 On assertion failure, print backtrace if available.
7026 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7027 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7028 * Makefile.in (LIB_EXECINFO): New macro.
7031 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7032 * bytecode.c (exec_byte_code):
7033 * callint.c (check_mark, Fcall_interactively):
7034 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7035 (getenv_internal, sync_process_alive, call_process_exited):
7036 * lisp.h (USE_SAFE_ALLOCA):
7037 Use bool for booleans, instead of int.
7038 * lisp.h, process.h: Adjust prototypes to match above changes.
7039 * callint.c (Fcall_interactively): Don't assume the mark's
7040 offset fits in 'int'.
7042 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7044 * buffer.c, buffer.h: Use bool for boolean.
7045 * buffer.c (reset_buffer_local_variables)
7046 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7047 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
7048 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
7049 (overlay_touches_p, overlay_strings, Foverlay_put)
7050 (report_overlay_modification, call_overlay_mod_hooks):
7051 (mmap_enlarge, mmap_set_vars):
7052 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7053 Use bool for booleans, instead of int.
7054 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7055 since the 1-or-0 return value is always ignored anyway.
7056 (mmap_initialized_p):
7057 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7058 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7060 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7062 * bidi.c: Use bool for boolean.
7063 This is a bit more readable, and makes the text segment of bidi.o
7064 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7065 Presumably it's faster too.
7066 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7068 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7069 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7070 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7071 (bidi_explicit_dir_char, bidi_level_of_next_char)
7072 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7073 Use bool for booleans, instead of int.
7074 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7075 (bidi_unshelve_cache): Adjust decls to match code.
7077 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7079 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7082 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7084 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7085 * atimer.h: Include <stdbool.h>.
7087 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7089 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7090 compile time tests instead of run time tests on systems that do
7092 (FRAME_MAC_P): Remove leftover from deleted code.
7093 * frame.c (syms_of_frame): Remove leftover from deleted code.
7095 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7097 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7099 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7101 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7102 Otherwise, the compiler complains about (A?B:C) where B is void
7103 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7104 (fontset_add): Return void, for FONTSET_ADD.
7106 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7108 * alloc.c: Use bool for booleans.
7109 (gc_in_progress, abort_on_gc)
7110 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7111 (dont_register_blocks) [GC_MALLOC_CHECK]:
7112 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7113 (check_string_bytes, make_specified_string, memory_full)
7114 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7115 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7116 (mark_stack, valid_pointer_p, make_pure_string)
7117 (Fgarbage_collect, survives_gc_p, gc_sweep):
7118 Use bool for booleans, instead of int.
7119 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7120 Remove unused local.
7121 * alloc.c (PURE_POINTER_P):
7122 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7123 * editfns.c (Fformat):
7124 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7126 * fns.c (sweep_weak_table):
7127 * lisp.h (suppress_checking, push_message, survives_gc_p)
7128 (make_pure_string, gc_in_progress, abort_on_gc):
7129 * lread.c (readchar, read1):
7130 * print.c (Fprin1_to_string):
7131 * xdisp.c (push_message):
7132 Use bool for booleans affected directly or indirectly by
7135 Make recently-introduced setters macros.
7136 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7137 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7138 (set_fontset_default, set_fontset_fallback): Rename from their
7139 upper-case counterparts, and make them functions rather than macros.
7140 This is more consistent with the other recently-introduced setters.
7141 These don't need to be inline, since they're local.
7143 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7145 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7146 the loop (Bug#12247).
7148 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7150 * lisp.h (vcopy): Use memcpy rather than our own loop.
7151 This fixes a performance regression introduced by the recent
7152 addition of vcopy. This means 'vcopy' will need to be modified
7153 for a copying collector, but that's OK. Also, tighten the
7154 checking in the assertion.
7156 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7158 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7159 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7160 non-base glyph for the width of the base character, according to
7161 what x_draw_composite_glyph_string_foreground expects.
7162 Generate WADJUST value according to composition_gstring_width's
7163 expectations, to produce correct width of the composed character.
7164 Reverse the sign of the DU offset produced by ScriptPlace.
7166 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7168 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7170 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7172 Avoid direct writes to contents member of struct Lisp_Vector.
7173 * lisp.h (vcopy): New function to copy data into vector.
7174 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7175 * fns.c (Ffillarray): Use ASET.
7176 * keyboard.c (timer_check_2): Use AREF and ASET.
7177 (append_tool_bar_item, Frecent_keys): Use vcopy.
7178 * lread.c (read_vector): Use ASET.
7179 * msdos.c (Frecent_doskeys): Use vcopy.
7180 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7181 (Finternal_merge_in_global_face): Use ASET and vcopy.
7182 * xfont.c (xfont_list_pattern): Likewise.
7184 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7186 * window.c (Fwindow_point): For the selected window always return
7187 the position of its buffer's point.
7188 (Fset_window_point): For the selected window always go in its
7189 buffer to the specified position.
7191 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7193 Setter macros for fontsets.
7194 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7195 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7196 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7199 2012-08-20 Glenn Morris <rgm@gnu.org>
7201 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7202 Don't assume that `ln -f' works.
7204 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7206 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7207 and later about non-assignments with no effect. See discussion at
7208 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7211 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7213 Inline setter functions for Lisp_Objects slots of struct specbinding.
7214 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7217 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7219 * window.c (select_window): Always make selected window's buffer
7222 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7224 Use AREF and ASET for docstrings of category tables.
7225 * category.h (CATEGORY_DOCSTRING): Use AREF.
7226 (SET_CATEGORY_DOCSTRING): Use ASET.
7227 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7229 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7231 Inline setter functions for hash table members.
7232 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7233 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7234 (set_hash_key_and_value, set_hash_index, set_hash_next)
7235 (set_hash_hash): New functions.
7236 * charset.c, fns.c: Adjust users.
7238 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7240 Inline getter and setter functions for per-buffer values.
7241 * buffer.h (per_buffer_default, set_per_buffer_default)
7242 (per_buffer_value, set_per_buffer_value): New functions.
7243 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7244 * buffer.c, data.c: Adjust users.
7246 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7248 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7250 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7252 Rely on <config.h> + <unistd.h> to declare 'environ',
7253 as gnulib does this if the system doesn't.
7254 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7255 Remove declaration. MS-Windows declares it on stdlib.h which is
7256 included by conf_post.h.
7257 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7258 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7259 * vm-limit.c: Include <unistd.h>, for 'environ'.
7261 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7262 (start_of_data): Remove decl; mem-limits.h provides it.
7264 * xdisp.c (handle_invisible_prop): Make it a bit faster
7265 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7267 2012-08-19 Chong Yidong <cyd@gnu.org>
7269 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7272 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7274 * .gdbinit: Use call instead of set when calling a function in the
7277 * data.c (set_internal): Don't use set_blv_found.
7278 (Fkill_local_variable): Likewise.
7280 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7282 * nsfont.m (ns_ascii_average_width): Ensure the string
7283 ascii_printable is initialized with a null-terminated character
7284 array. Otherwise, it can contain undesired extra characters.
7286 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7288 port new setting code to Sun C 5.8 2005/10/13
7289 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7290 Return void, not Lisp_Object. Otherwise, the compiler
7291 complains about (A?B:C) where B is void and C is Lisp_Object
7292 when compiling CHAR_TABLE_SET, due to the recent change to

8161 Now constants, not macros.
8163 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
8165 Remove unnecessary casts involving pointers.
8166 These casts are no longer needed now that we assume C89 or later,
8167 since they involve casting to or from void *.
8168 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
8169 (make_pure_float, make_pure_vector):
8170 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

8178 * xselect.c (x_stop_queuing_selection_requests)
8179 (x_get_window_property, x_get_window_property_as_lisp_data):
8180 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8181 Remove unnecessary pointer casts.
8182 * alloc.c (record_xmalloc): New function.
8183 * lisp.h (record_xmalloc): New decl.
8184 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8185 more like a function. This is because the pointer cast is not
8186 needed. All uses changed.
8187 * print.c (print_string, print_error_message): Avoid length recalc.
8189 Improve fix for macroexp crash with debugging (Bug#12118).
8190 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8191 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8192 not supposed to be invoked from the garbage collector.
8193 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
8194 (gc_aset): New function, which is like ASET but can be
8195 used in the garbage collector.
8196 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
8197 (set_hash_index): Use it instead of ASET.

8209 (map_w32_filename): Improve commentary. Simplify switch.
8210 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
8211 headers (most versions of MinGW w32api don't).
8212 (get_security_info, create_symbolic_link)
8213 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
8215 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
8216 in the argument file name.

8219 (sys_rename): Diagnose renaming of a symlink when the user doesn't
8220 have the required privileges.
8221 (get_file_security_desc_by_name): Rename from
8222 get_file_security_desc.
8223 (stat_worker): New function, with most of the guts of 'stat', and
8224 with addition of handling of symlinks and support for 'lstat'.
8225 If possible, get file's attributes and security information by
8226 handle, not by name. Produce S_IFLNK bit for symlinks, when
8227 called from 'lstat'.
8228 (stat, lstat): New functions, call 'stat_worker'.
8229 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8230 symlinks when the underlying filesystem supports them.
8232 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8234 Fix macroexp crash on Windows with debugging (Bug#12118).
8235 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8236 checking subscripts; problem introduced with the recent
8237 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8238 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8239 since it's used in non-static inline functions now.
8241 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8242 Don't assume buffer size fits in 'int'. Remove unused local.

8254 * buffer.h, category.h, character.h, charset.h, composite.h:
8255 * dispextern.h, lisp.h, systime.h:
8256 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
8257 * alloc.c (LISP_INLINE):
8258 * buffer.c (BUFFER_INLINE):
8259 * category.c (CATEGORY_INLINE):
8260 * character.c (CHARACTER_INLINE):
8261 * charset.c (CHARSET_INLINE):
8262 * composite.c (COMPOSITE_INLINE):
8263 * dispnew.c (DISPEXTERN_INLINE):
8264 * sysdep.c (SYSTIME_INLINE):
8265 Define to EXTERN_INLINE, so that the corresponding functions
8266 are compiled into code.
8267 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8268 (INLINE_HEADER_END): New macros.
8269 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8289 hard-coding the path separator.
8291 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8293 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8294 This how ASET and AREF are supposed to work, and makes
8295 it easier to think about future improvements. See
8296 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8297 * charset.h (set_charset_attr): New function.
8298 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
8299 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

8712 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
8713 enumeration constants, as PURE and HEAP are too general, and clash
8714 with other headers and sources, such as gmalloc.c and the
8715 MS-Windows system headers. All users changed.
8717 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8719 Revert last save_excursion_save and save_excursion_restore changes.
8720 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

8733 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8734 arms of an 'if', not using conditional expressions; otherwise GDB
8735 complains about the types in the unevaluated arm when the argument
8736 is an integer literal.
8737 (xgetint): Simplify expression.
8738 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8739 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8740 Zaretskii in <http://bugs.gnu.org/12036#13>.
8741 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8742 needed now that we have gdb_make_enums_visible.
8743 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8744 (enum enum_USE_LSB_TAG):
8745 New enum types, packaging up enums that need to be exported to GDB.

8787 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8788 emacs.c, as this is a more-suitable home. Had this been done earlier
8789 the fix for 12036 would have avoided some of the problems noted in
8790 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8791 would have been more obvious.
8792 * emacs.c: Do not include <verify.h>; no longer needed.
8793 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8794 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8795 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

8800 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8801 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8802 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8803 not be usable in #if. This simplifies things.
8805 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8807 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

8812 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8813 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8814 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8815 Adjust to changes in lisp.h and emacs.c, by using
8816 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8817 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8818 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8819 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8820 instead of gdb_valbits.
8821 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8822 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8823 instead of gdb_array_mark_flag.
8824 (xboolvector): Get size from $->size, not $->header.size.
8825 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8826 (xreload, hook-run, hookpost-run): Remove.
8827 * emacs.c: Include <verify.h>.
8828 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8829 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8831 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8832 (gdb_USE_LSB_TAG): New enum constants.
8833 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8834 Also define these as enum constants, so they're visible to GDB.
8835 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8836 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8837 as constants, so they're visible to GDB.

8840 Now enum constants, not macros, so they're visible to GDB.
8841 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8842 more convenient now. All uses changed.
8843 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8844 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8846 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8853 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8854 add argument, tune behavior, and adjust all callers.
8856 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8858 Use typedef for EMACS_INT, EMACS_UINT.
8859 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8860 than macros. This simplifies debugging in the usual case, since
8861 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8862 and it allows expressions involving EMACS_INT casts.
8863 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8865 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8875 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8877 Adjust buffer text indirection counters at the end of Fkill_buffer.
8878 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8879 buffer is definitely dead. This should really fix an issue reported
8880 by Christoph Scholtes again. (Bug#12007).
8881 (init_buffer_once): Initialize indirection counters of
8882 buffer_defaults and buffer_local_symbols (for sanity and safety).
8884 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8886 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8887 and continuation glyphs on tooltip frames, leave them at zero.

8890 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
8892 Simplify copy_overlay.
8893 * buffer.c (copy_overlay): Simplify. Use build_marker.

8902 it signals an error when a tooltip frame is being created.
8904 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8906 Cleanup miscellaneous objects allocation and initialization.

8913 (build_overlay): Add prototype.
8915 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8917 Swap buffer text indirection counters in Fbuffer_swap_text.
8918 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8919 This avoids crash reported by Christoph Scholtes at
8920 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8922 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8924 * nsmenu.m (Popdown_data): New struct.
8925 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8927 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
8928 (initWithContentRect): Make imgView and contentView non-static
8929 and autorelease them. Also autorelease img and matrix (Bug#12005).
8930 (dealloc): Remove (Bug#12005).
8932 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
8934 Adjust consing_since_gc when objects are explicitly freed.

8947 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8949 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8950 as it's limited by the amount of memory, not by INT_MAX.
8952 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8954 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8955 in special-event-map. See the discussion at
8956 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
8959 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
8960 info.dwItemData. Fixes crashes on 64-bit Windows.

9011 * lisp.h (build_unibyte_string): New function.
9012 * dosfns.c, fileio.c, fns.c, ftfont.c, process.c:
9013 * sysdep.c, w32fns.c, xfns.c: Use it.
9014 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
9015 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
9016 Adjust users accordingly.
9017 * font.h (font_open_by_name): Adjust prototype.
9019 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

9035 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
9036 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
9037 'for_each_per_buffer_object_at'.
9038 All uses changed. It's better to use upper-case for macros that

9678 * s/aix4-2.h (unix): Remove; no longer needed.
9680 EMACS_TIME simplification (Bug#11875).
9681 This replaces macros (which typically do not work in GDB)

9683 The functional style also makes code easier to read and maintain.
9684 * systime.h: Include <sys/time.h> on all hosts, not just if
9685 WINDOWSNT, since 'struct timeval' is needed in general.

9701 (add_emacs_time, sub_emacs_time): New functions.
9702 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

9723 * nsterm.m: Include <ftoastr.h>.
9725 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9726 Prefer snprintf to strncpy.
9727 * nsterm.m (ns_term_init):
9728 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9729 * nsterm.m (ns_term_init):
9730 Avoid the need for strncpy, by using build_string or
9731 make_unibyte_string directly. Use dtoastr, not snprintf.
9732 * process.c (Fmake_network_process): Diagnose service names that
9733 are too long, rather than silently truncating them or creating
9734 non-null-terminated names.

9751 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9752 where argument type is known to be a Lisp_Cons.

9807 O_RDONLY already includes it).
9809 Stop ns builds setting the EMACSLOADPATH environment variable.

9813 * lread.c [HAVE_NS]: Include nsterm.h.
9814 (init_lread) [HAVE_NS]: Use ns_load_path.

9824 (ns_init_paths): Do not set EMACSPATH.

9884 Move marker debugging code under MARKER_DEBUG.
9885 * marker.c (MARKER_DEBUG): Move marker debugging code under
9886 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9887 for bootstrap with --enable-checking (~3x slowdown reported

9941 * lread.c (load_path_check): New function, split from init_lread.
9942 (init_lread): Reorganize. Motivation:
9943 If EMACSLOADPATH is set, check/warn about that rather than the
9944 defaults, which we are not going to use. Hence we can remove
9945 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9946 Don't warn if site-lisp directories are missing.
9947 If not installed, start from a blank load-path, since
9948 PATH_LOADSEARCH refers to the eventual installation directories.
9950 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9952 Support truncation and continuation glyphs on GUI frames, when
9953 fringes are disabled. (Bug#11832)
9954 * xdisp.c (init_iterator): Get dimensions of truncation and
9955 continuation glyphs even if on GUI frames.
9956 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9957 or both, are absent.
9958 (start_display, move_it_in_display_line_to): Handle the case of a
9959 GUI frame without a fringe to display continuation or truncation
9961 (insert_left_trunc_glyphs): Support GUI frames: make sure
9962 truncation glyphs overwrite enough glyphs from the current line to
9963 have sufficient space in pixels.
9964 (display_line): Support truncation and continuation glyphs on GUI
9965 frames. If some spare pixels are left on the line after inserting
9966 the truncation glyphs, fill that space with a stretch glyph of a
9967 suitably computed width.
9969 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9970 produce_glyphs, to support GUI sessions.
9972 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9974 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9976 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9978 Do not require float-time's arg to fit in time_t (Bug#11825).
9979 This works better on hosts where time_t is unsigned, and where
9980 float-time is applied to the (negative) difference between two times.
9981 * editfns.c (decode_time_components): Last arg is now double *,
9982 not int *, and means to store all the result as a double, without
9983 worrying about whether the seconds part fits in time_t.
9984 All callers changed.
9985 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9986 All callers changed.
9987 (Ffloat_time): Do not fail merely because the specified time falls
9988 outside of time_t range.
9990 2012-07-07 Glenn Morris <rgm@gnu.org>
9992 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
9993 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
9994 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
9996 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9998 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9999 Update dependencies.
10001 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10003 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10005 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

10007 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10008 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10009 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10010 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10012 * xfont.c (compare_font_names): Redo to omit the need for casts.
10014 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10016 * xfns.c (Fx_change_window_property): Doc fix.
10017 * w32fns.c (Fx_change_window_property): Doc fix.
10019 * w32fns.c (Fx_window_property): Accept the same arguments as the
10020 X Windows version. Doc fix.
10021 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10023 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10024 Eli Zaretskii <eliz@gnu.org>
10026 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10027 Windows-specific code from nt/config.nt moved here.
10028 Obsolete settings removed.
10030 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10032 * process.c: Avoid unnecessary calls to gettime.
10033 (wait_reading_process_output): Don't get the time of day
10034 when gobbling data immediately and not waiting, as there's no need
10035 for it in that case. This removes a FIXME.
10037 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10039 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10040 is defined (Bug#11768).
10042 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10044 Fix marker debugging code.
10045 * marker.c (byte_char_debug_check): Do not perform the check
10046 if buffer is not multibyte.
10047 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10048 Call byte_char_debug_check with correct arguments.
10050 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10052 Compile marker debugging code only if ENABLE_CHECKING is defined.
10053 * marker.c (byte_char_debug_check, count_markers):
10054 Use only if ENABLE_CHECKING is defined.
10055 (byte_debug_flag): Remove.
10056 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10057 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10059 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10061 Avoid code repetition in marker-related functions.
10062 * marker.c (attach_marker): New function.
10063 (Fset_marker, set_marker_restricted, set_marker_both)
10064 (set_marker_restricted_both): Use it.
10065 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
10066 Consistently rename charno to charpos.
10067 (marker_position): Add eassert.
10068 (marker_byte_position): Convert to eassert.
10070 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10072 Simplify list operations in unchain_overlay and unchain_marker.
10073 * buffer.c (unchain_overlay): Simplify. Add comment.
10074 * marker.c (unchain_marker): Simplify. Fix comments.
10076 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10078 Introduce fast path for the widely used marker operation.
10079 * alloc.c (build_marker): New function.

10081 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
10082 * composite.c (autocmp_chars): Likewise.
10083 * editfns.c (buildmark): Remove.
10084 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10085 (save_restriction_save): Use build_marker.
10086 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10087 * window.c (save_window_save): Likewise.
10089 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10091 Do not use Fdelete_overlay in delete_all_overlays
10092 to avoid redundant calls to unchain_overlay.
10093 * buffer.c (drop_overlay): New function.
10094 (delete_all_overlays, Fdelete_overlay): Use it.
10095 * minibuf.c (get_minibuffer): Fix comment.
10097 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10099 Port to OpenBSD 5.1 amd64.
10100 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10101 This is needed for OpenBSD, and should be harmless on all BSD systems.
10102 Also, include <sys/sysctl.h>, as it should be available on all
10103 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10104 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10105 use p_pid member, not kp_proc.pid.
10107 2012-07-06 Glenn Morris <rgm@gnu.org>
10109 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10111 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10113 More xmalloc and related cleanup.
10114 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
10115 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
10116 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

10122 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10124 Omit needless casts involving void * pointers and allocation.
10125 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10126 as the former is more robust if P's type is changed.
10127 Prefer xzalloc to xmalloc + memset 0.
10128 Simplify malloc-or-realloc to realloc.
10129 Don't worry about xmalloc returning a null pointer.
10130 Prefer xstrdup to xmalloc + strcpy.
10131 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10133 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10134 alloca of a constant.
10136 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10138 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10139 hscroll is larger than the line width. Fixes long and futile
10140 looping inside extend_face_to_end_of_line (on a TTY) producing
10141 glyphs that are not needed and thrown away.
10143 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10145 * marker.c (set_marker_restricted_both): Simplify by using
10148 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10150 * editfns.c (region_limit): Simplify by using clip_to_bounds.
10152 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
10154 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
10155 not defined (Bug#11768).
10156 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
10157 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
10158 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
10159 followed by gtk_box_set_homogeneous (Bug#11768).
10160 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10161 (update_theme_scrollbar_width, xg_create_scroll_bar):
10162 Use gtk_scrollbar_new (Bug#11768).
10163 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
10164 (is_box_type): New function (Bug#11768).
10165 (xg_tool_item_stale_p): Call is_box_type.
10166 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10167 with default display (Bug#11768).
10169 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10171 * xdisp.c (window_hscroll_limited): New function.
10172 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10173 coordinates when window's hscroll is set to insanely large
10174 values. (Bug#11857)
10176 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
10178 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
10179 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

10237 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10239 * fileio.c (time_error_value): Check the right error number.
10240 Problem reported by Troels Nielsen in
10241 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10243 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10245 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10246 This should be fixed in a better way; see Eli Zaretskii in
10247 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10248 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10250 * fileio.c (time_error_value): Rename from special_mtime.
10251 The old name's problems were noted by Eli Zaretskii in
10252 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10254 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10255 This variable's comment says Emacs needs at least one GDB-visible
10256 symbol of type enum pvec_type, to work around GDB problems.
10257 The symbol's value doesn't matter.
10259 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10260 that causes compilation to fail on pre-C99 compilers.
10262 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10264 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10265 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10267 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10269 * buffer.c (init_buffer_once): Fix initialization of
10270 headers for buffer_defaults and buffer_local_symbols.
10271 Reported by Juanma Barranquero <lekktu@gmail.com>.
10273 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10275 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10276 * lisp.h (enum pvec_type): Use fewer bits.
10277 (PSEUDOVECTOR_SIZE_BITS): New constant.
10278 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10279 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10280 change in pvec_type.
10281 (PSEUDOVECTOR_TYPEP): New macro.
10282 (TYPED_PSEUDOVECTORP): Use it.
10283 * fns.c (internal_equal): Adapt code to extract pvectype.
10284 * emacs.c (gdb_pvec_type): Update type.
10285 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10286 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10287 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10288 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10289 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10290 abusing vector->header.next.nbytes.
10291 (live_vector_p): Use PVEC_TYPE.
10292 (mark_object): Adapt code to extract pvectype. Use switch.
10294 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10296 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10297 Tighten new eassert a bit.
10299 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10301 Fix compilation with --enable-gcc-warnings and -O1
10302 optimization level.
10303 * doprnt.c (doprnt): Change type of tem to int, initialize
10304 to avoid compiler warning. Add eassert.
10305 * search.c (simple_search): Initialize match_byte to avoid
10306 compiler warning. Add eassert.
10308 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10310 Avoid weird behavior with large horizontal scrolls.
10311 Without this change, for example, large hscroll values would
10312 mess up Emacs's display on Fedora 15 x86, presumably due to
10313 overflows in int calculations in the display code.
10314 Also, if buffers had long lines, Emacs would freeze.
10315 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10316 (set_window_hscroll): New function, containing the old guts of
10317 Fset_window_hscroll. Return the clipped value.
10318 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10319 This avoids the need to check against PTRDIFF_MAX.
10321 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10323 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10325 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10327 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10329 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10330 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10331 since GCC 4.4.6 issues a bogus warning for them.
10333 Fix bugs in file timestamp newness comparisons.
10334 * fileio.c (Ffile_newer_than_file_p):
10335 * lread.c (Fload): Use full timestamp resolution of files,
10336 not just the 1-second resolution, so that files that are only
10337 slightly newer still count as newer.
10338 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10339 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10341 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10343 * fileio.c: Improve handling of file time marker. (Bug#11852)
10344 (special_mtime): New function.
10345 (Finsert_file_contents, Fverify_visited_file_modtime):
10346 Use it to set special mtime values consistently.
10348 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10350 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10351 marker for non-existing file. (Bug#11852)
10353 2012-07-03 Glenn Morris <rgm@gnu.org>
10355 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10356 and did not make it into globals.h).
10358 2012-07-03 Tom Tromey <tromey@redhat.com>
10360 * window.c (Fset_window_margins, Fset_window_fringes)

10396 2012-07-03 Glenn Morris <rgm@gnu.org>
10398 * lisp.h (Frandom): Make it visible to C.
10399 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10400 buffer for invisible buffers. (Bug#1229)
10402 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10404 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10405 values which aren't power of 2.
10406 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10407 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10410 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10412 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10414 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10416 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10418 * alloc.c (allocate_vector_block): Remove redundant
10419 calls to mallopt if DOUG_LEA_MALLOC is defined.
10420 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10421 avoid calls to mallopt if zero_vector is returned.
10423 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10425 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10426 is enabled, avoid dereferencing NULL current_sblock if
10429 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10431 Cleanup basic buffer management.
10432 * buffer.h (struct buffer): Change layout to use generic vector
10433 marking code. Fix some comments. Change type of 'clip_changed'
10434 to bitfield. Remove unused #ifndef old.
10435 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10436 (GET_OVERLAYS_AT): Fix indentation.
10437 (for_each_per_buffer_object_at): New macro.
10438 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10439 (Fbuffer_local_variables): Use it.
10440 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
10441 * alloc.c (allocate_buffer): Adjust to match new layout of
10442 struct buffer. Fix comment.
10443 (mark_overlay): New function.
10444 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10445 Lisp area of struct buffer.
10446 (mark_object): Use it. Adjust marking of misc objects
10447 and related comments.
10449 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10451 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10452 wrapper that is not needed because the wrapped code is a no-op (zero
10453 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10454 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10456 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10458 * alloc.c (mark_buffer): Simplify. Remove prototype.
10459 (mark_object): Add comment. Reorganize marking of vector-like
10460 objects. Use CHECK_LIVE for all vector-like objects except buffers
10461 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10462 Avoid redundant calls to mark_vectorlike for bool vectors.
10464 2012-06-30 Glenn Morris <rgm@gnu.org>
10466 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10468 * epaths.in (PATH_SITELOADSEARCH): New.
10469 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10470 This is rather than relying on --enable-locallisppath elements
10471 having "site-lisp" in their names. (Bug#10208#25, 11658)
10473 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10475 * w32proc.c (sys_select): Accept and ignore one more argument.
10477 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10479 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10480 (pselect) [!MS_DOS]: Redirect to sys_select.
10482 * sysdep.c: Don't include dos.h and dosfns.h.
10484 * process.c (sys_select):
10485 * msdos.c (sys_select): Accept one more argument and ignore it.
10487 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10488 adapt data types and code to that.
10491 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10492 which clashes with the gnulib function of the same name.
10494 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10496 * font.c (font_style_to_value, font_style_symbolic)
10497 (font_prop_validate_style): Add type checks for values in
10500 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10502 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10505 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10507 * xdisp.c (try_window_id): Undo last change.
10509 * w32.c (getwd): Adjust commentary about startup_dir.
10510 (init_environment): Always call sys_access, even in non-MSVC
10511 builds. Don't chdir to the directory of the Emacs executable.
10512 This undoes code from 1997 which was justified by the need to
10513 "avoid conflicts when removing and renaming directories". But its
10514 downside was that every relative file name was being interpreted
10515 relative to the directory of the Emacs executable, which can never
10516 be TRT. In particular, it broke sys_access when called with
10517 relative file names.
10518 (sys_access): Map GetLastError to errno.
10520 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

10526 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10529 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10531 * gnutls.c (emacs_gnutls_handshake):
10532 Add QUIT to make the loop interruptible.
10534 2012-06-29 Glenn Morris <rgm@gnu.org>
10536 * charset.c (init_charset): Make lack of etc/charsets fatal.
10538 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10540 * editfns.c (region_limit): Fix type mismatch.
10542 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10544 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10545 undefined. Convert from xassert to eassert.
10546 * nsmenu.m: Convert from xassert to eassert.
10547 * nsterm.m: Likewise.
10549 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

10553 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10555 Avoid integer overflow on scroll-left and scroll-right.
10556 * window.c (HSCROLL_MAX): New macro.
10557 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10558 overflow when requested scroll falls outside ptrdiff_t range.
10560 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10562 * window.h (struct window): Change type of 'hscroll',
10563 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10564 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10565 Adjust users accordingly.
10566 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10567 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10568 from EMACS_INT to ptrdiff_t.
10569 (make_window): Omit redundant initialization.

10588 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10589 adjust comments accordingly.

10638 * alloc.c (allocate_string_data): Remove dead code.
10639 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to

10710 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10712 Use sprintf return value instead of invoking strlen on result.
10713 In the old days this wasn't portable, since some sprintf
10714 implementations returned char *. But they died out years ago and
10715 Emacs already assumes sprintf returns int.
10716 Similarly for float_to_string.
10717 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10723 * xdisp.c (message_dolog):
10724 * xfns.c (syms_of_xfns):
10725 Use sprintf or float_to_string result to avoid need to call strlen.
10726 * data.c (Fnumber_to_string):
10727 Use make_unibyte_string, since the string must be ASCII.
10728 * lisp.h, print.c (float_to_string): Now returns int length.
10729 * term.c (produce_glyphless_glyph):
10730 Use sprintf result rather than recomputing it.
10732 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10733 * Makefile.in (ALL_CFLAGS):

10759 sprintf already null-terminates its output.
10761 * xfns.c (x_window): Remove redundant cast.
10763 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10765 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10766 `const char *' to `char *' to avoid compiler warning.
10768 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10770 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10771 instead of truncating it to 63 (admittedly a generous limit).
10773 * process.c: Fix spelling and caps in comments.
10775 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10777 * emacs.c (setpgrp): Remove definition, unused.

10824 Remove unnecessary forward decls.
10826 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10828 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10829 * lisp.h (WAIT_READING_MAX): New macro.
10830 * dispnew.c (Fsleep_for, sit_for):
10831 * keyboard.c (kbd_buffer_get_event):
10832 * process.c (Faccept_process_output):
10833 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10834 This improves on the previous patch, which introduced a bug
10835 when time_t is unsigned and as wide as intmax_t.
10836 See <http://bugs.gnu.org/9000#51>.

10856 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
10858 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

10864 last argument of make_unibyte_string.
10866 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
10867 language ID in the event parameters.
10869 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10870 event.code, not the obscure "character set ID".
10872 2012-06-23 Chong Yidong <cyd@gnu.org>
10874 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

10897 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
10898 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
10899 Don't assume EMACS_TIME and struct timeval are the same type.
10901 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10903 Support higher-resolution time stamps (Bug#9000).
10904 The time stamps are only nanosecond-resolution at the C level,
10905 since that's the best that any real-world system supports now.
10906 But they are picosecond-resolution at the Lisp level, as that's
10907 easy, and leaves room for future OS improvements.
10909 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10912 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10913 Don't get current time unless it's needed.
10915 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10916 now provides it if it's absent.
10917 (start_atimer): Port to higher-res time stamps.
10918 Check for time stamp overflow. Don't get current time more
10919 often than is needed.
10921 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10922 Include systime.h, not time.h.
10923 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10925 * dired.c: Include stat-time.h.
10926 (Ffile-attributes): File times now have higher resolution.
10928 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10929 (struct image): Timestamp now has higher resolution.
10931 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10932 has at least microseconds now. All uses removed.
10933 (update_frame, update_single_window, update_window, update_frame_1)
10934 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10935 (duration_to_sec_usec): Remove; no longer needed.
10937 * editfns.c (time_overflow): Now extern.
10938 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10939 (float-time, Fformat_time_string, Fcurrent_time_string)
10940 (Fcurrent_time_zone): Accept and generate higher-resolution

10943 (decode_time_components, lisp_seconds_argument): New functions.
10944 (make_time): Now static.
10945 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10946 Report an error if the time is invalid, rather than having the caller
10949 * fileio.c: Include <stat-time.h>
10950 (Fcopy_file): Copy higher-resolution time stamps.
10951 Prefer to set the time stamp via a file descriptor if that works.
10952 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10953 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10954 (Fvisited_file_modtime, Fset_visited_file_modtime):
10955 Support higher-resolution time stamps.
10957 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10959 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10961 * image.c (prepare_image_for_display, clear_image_cache)
10962 (lookup_image): Port to higer-resolution time stamps.
10964 * keyboard.c (start_polling, bind_polling_period):
10965 Check for time stamp overflow.
10966 (read_char, kbd_buffer_get_event, timer_start_idle)
10967 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10968 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10969 Port to higher-resolution time stamps. Do not assume time_t is signed.
10970 (decode_timer): New function. Timers are now vectors of length 9,
10971 not 8, to accommodate the picosecond component.
10972 (timer_check_2): Use it.
10974 * nsterm.m (select_timeout, timeval_subtract): Remove.
10975 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10976 as they're a bit more accurate and handle overflow better.
10977 (ns_select): Change prototype to be compatible with pselect.
10978 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10979 * nsterm.h (ns_select): Adjust prototype.
10981 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10982 us-resolution time stamps.
10983 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10985 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10987 * lisp.h (time_overflow): New decl.
10988 (wait_reading_process_output): First arg is now intmax_t, not int,
10989 to accommodate larger waits.
10991 * process.h (struct Lisp_Process.read_output_delay):
10992 Now counts nanoseconds, not microseconds.
10993 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10995 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10996 (wait_reading_process_output):
10997 Port to ns-resolution time stamps.
10998 (Faccept_process_output, wait_reading_process_output):
10999 Check for time stamp overflow. Do not assume time_t is signed.
11000 (select_wrapper): Remove; we now use pselect.
11001 (Fprocess_attributes): Now generates ns-resolution time stamps.
11003 * sysdep.c: Include utimens.h. Don't include utime.h
11004 or worry about struct utimbuf; gnulib does that for us now.
11005 (gettimeofday): Remove; gnulib provides a substitute.
11006 (make_timeval): New function.
11007 (set_file_times): Now sets ns-resolution time stamps.
11008 New arg FD; all uses changed.
11009 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11010 (system_process_attributes):
11011 Now returns ns-resolution time stamp. All uses changed.
11012 Check for time stamp overflow.
11014 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11015 provides a substitute now.
11017 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11018 since it guarantees struct timespec.
11019 (EMACS_TIME): Now struct timespec, so that we can support
11020 ns-resolution time stamps.
11021 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11022 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11023 (EMACS_USECS): Remove.
11024 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11025 so multiply the arg by 1000 before storing it.
11026 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11028 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11029 Port to ns-resolution time stamps.
11030 (EMACS_TIME_NEG_P): Remove; replaced by....
11031 (EMACS_TIME_SIGN): New macro.
11032 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
11033 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
11034 (set_file_times, make_time, lisp_time_argument): Adjust signature.
11035 (make_timeval, make_lisp_time, decode_time_components): New decls.
11036 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11037 that it mishandled time_t overflow. You can't compare by subtracting!
11038 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11039 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11041 * term.c: Include <sys/time.h>.
11042 (timeval_to_Time): New function, for proper overflow wraparound.
11043 (term_mouse_position, term_mouse_click): Use it.
11045 * undo.c (record_first_change): Support higher-resolution time stamps
11046 in the undo buffer.
11047 (Fprimitive_undo): Use them when restoring time stamps.
11049 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11050 (w32_get_internal_run_time):
11051 Port to higher-resolution Emacs time stamps.
11052 (ltime): Now accepts single 64-bit integer, as that's more convenient
11055 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11057 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11058 for compatibility with pselect. Support ns-resolution time stamps.
11060 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11062 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11063 Check for time stamp overflow, and support ns-resolution time stamps.
11065 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11066 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11067 (timeval_subtract): Remove; no longer needed.
11068 (XTflash, XTring_bell, x_wait_for_event):
11069 Port to ns-resolution time stamps. Don't assume time_t is signed.
11071 2012-06-22 Chong Yidong <cyd@gnu.org>

11075 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11077 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11078 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11079 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11080 staticidx goes up to 1597 out of 1600 = 0x640.)
11082 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11084 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
11085 Otherwise, the umask might be mistakenly 0 while handling input signals.
11087 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
11089 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

11095 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
11096 access to `contents' member of Lisp_Vector objects with AREF and ASET
11099 2012-06-19 Chong Yidong <cyd@gnu.org>
11101 * frame.c (delete_frame): When selecting a frame on a different
11102 text terminal, do not alter the terminal's top-frame.
11104 * xdisp.c (format_mode_line_unwind_data): Record the target
11105 frame's selected window and its terminal's top-frame.
11106 (unwind_format_mode_line): Restore them.
11107 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11109 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11110 since tty frames can be explicitly named.
11111 (prepare_menu_bars): Likewise.
11113 * term.c (Ftty_top_frame): New function.
11115 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

11118 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11119 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11120 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11121 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

11128 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11130 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11131 gets killed during executing of this function (Bug#11665).
11132 Try to always return Qt when the buffer has been actually killed.
11133 (Vkill_buffer_query_functions): In doc-string say that functions
11134 run by this hook should not change the current buffer.
11136 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11138 Fix recently-introduced process.c problems found by static checking.
11139 * process.c (write_queue_push, write_queue_pop, send_process):
11140 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
11141 (write_queue_pop): Fix pointer signedness problem.
11142 (send_process): Remove unused local.
11144 2012-06-17 Chong Yidong <cyd@gnu.org>

11156 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
11158 * lisp.h (eassert): Assume C89 or later.
11159 This removes the need for CHECK.
11160 (CHECK): Remove. Its comments about always evaluating its
11161 argument were confusing, as 'eassert' typically does not evaluate
11164 * coding.c (produce_chars): Use ptrdiff_t, not int.
11166 * xterm.c (x_draw_underwave): Check for integer overflow.
11167 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

11171 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
11172 referenced (Bug#11583).

11310 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
11312 (XLI, XIL): Define.
11313 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
11315 * emacs.c (gdb_use_struct): Rename from gdb_use_union.

11319 * frame.c (delete_frame): Remove outdated comment.
11320 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
11321 USE_LISP_UNION_TYPE.
11322 (Fw32_unregister_hot_key): Likewise.

11324 * w32menu.c (add_menu_item): Likewise.

11338 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
11340 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
11341 * alloc.c (make_number) [!defined make_number]:
11342 Remove, as lisp.h always defines this now.
11343 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
11344 (roundup_size): Verify that it is a power of 2.
11345 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):

11348 -DUSE_LSB_TAG=0, to override the automatically-selected default.
11349 USE_LSB_TAG now is always defined to be either 0 or 1.
11351 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
11352 code works fine either way, and efficiency is not a concern here,
11353 as the union type is for debugging, not for production.
11354 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
11355 Use an inline function on all platforms when using the union type,
11356 since this is simpler and 'static inline' can be used portably
11358 (LISP_INITIALLY_ZERO): New macro.
11359 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
11360 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

11388 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
11389 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
11391 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>

11428 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
11429 dbus_type_is_basic if available.
11430 (xd_extract_signed, xd_extract_unsigned): Rename from
11431 extract_signed and extract_unsigned, respectively. Adapt callers.

11442 * xdisp.c (vmessage): Treat frame message as multibyte.
11443 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
11444 would generate the diagnostic "Making \302\247 buffer-local while
11447 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11449 * dispnew.c (showing_window_margins_p): Undo last change, which

11460 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
11462 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
11463 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
11465 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11467 * alloc.c (allocate_vectorlike): Fix last change.
11469 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
11471 Block-based vector allocation of small vectors.
11472 * lisp.h (struct vectorlike_header): New field `nbytes',
11473 adjust comment accordingly.
11474 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
11475 to denote vector blocks. Adjust users (live_vector_p,
11476 mark_maybe_pointer, valid_lisp_object_p) accordingly.
11477 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
11478 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),

11498 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11500 * doprnt.c (doprnt): Truncate multibyte char correctly.
11501 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11502 would mishandle a string argument "Xc" if X was a multibyte
11503 character of length 2: it would truncate after X's first byte
11504 rather than including all of X.
11506 2012-06-06 Chong Yidong <cyd@gnu.org>
11508 * buffer.c (word_wrap): Doc fix.
11510 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

11539 Fbuffer_local_value; can return Qunbound.
11540 (Fbuffer_local_value): Use it.
11541 (Vmode_line_format): Docstring tweaks.

11555 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11557 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11558 Convert pctcpu and pctmem to Lisp float properly.
11559 Let the compiler fold better, as 100.0/0x8000 is exact.
11561 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11563 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11566 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

11570 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11572 For a 'struct window', replace some Lisp_Object fields to
11573 bitfields where appropriate, remove unused fields.
11574 * window.h (struct window): Remove unused 'last_mark_x' and
11575 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11576 change its type from Lisp_Object to bitfield.
11577 Change type of 'force_start', 'optional_new_start',
11578 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11579 fields from Lisp_Object to bitfield. Adjust users accordingly.
11581 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11583 Pacify gcc -Wdouble-precision when using Xaw.
11584 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11585 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11586 Use 'float' consistently, rather than 'float' in most places
11587 and 'double' in a couple of places.
11589 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11591 * xdisp.c (handle_stop): Detect whether we have overlay strings
11592 loaded by testing it->current.overlay_string_index to be
11593 non-negative, instead of checking whether n_overlay_strings is
11594 positive. (Bug#11587)
11596 2012-05-31 Chong Yidong <cyd@gnu.org>
11598 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11604 * search.c (search_buffer): Remove calls to
11605 r_alloc_inhibit_buffer_relocation, as it is now called by
11606 maybe_unify_char, which was the cause of relocation of buffer text
11609 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11611 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11612 for the duration of call to load_charset, to avoid problems with
11613 callers of maybe_unify_char that access buffer text through C
11616 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11617 decrement the inhibition flag, instead of just setting or
11620 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11622 Remove obsolete '#define static' cruft.
11623 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11624 This #undef was "temporary" in 2000; it is no longer needed
11625 now that '#define static' has gone away.
11626 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11627 (gray_bitmap_bits): Remove; no longer needed.
11628 All uses replaced with definiens.

11640 (safe_bcopy): Remove decl; no longer has that name.
11641 (main): Coalesce #if into single bit of code, for simplicity.
11642 Cast pointers to uintptr_t, since standard libraries want integers

11671 Do not create empty overlays with the evaporate property (Bug#9642).
11672 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11673 Bug#9642, but explicitly check that the buffer the overlay would
11674 be moved to is live and rearrange lines to make sure that errors
11675 will not put the overlay in an inconsistent state.
11676 (Fdelete_overlay): Cosmetics.
11678 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11680 * w32term.c (my_bring_window_to_top): New function.
11681 (x_raise_frame): Use handle returned by DeferWindowPos, which

11692 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11694 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11695 This avoids undefined behavior that might cause the eassert
11696 to not catch an out-of-range value.
11698 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11700 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

11715 Only r_alloc_inhibit_buffer_relocation needed to be added;
11716 the others were already declared.
11718 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11719 before checking whether it's out of range. Put the check inside
11721 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

11739 * search.c (search_buffer): Use it to inhibit relocation of buffer
11740 text while re_search_2 is doing its job, because re_search_2 is
11741 passed C pointers to buffer text. (Bug#11519)
11743 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11744 Update value to 24.
11746 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11747 state after an additional call to move_it_in_display_line_to, keep
11748 the values of it->max_ascent and it->max_descent found for the
11750 (pos_visible_p): Revert the comparison against bottom_y to what it
11751 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.

11756 Fix coding-related core dumps with gcc -ftrapv.
11757 The code was computing A - B, where A and B are pointers, and B is
11758 random garbage. This can lead to core dumps on platforms that
11759 have special pointer registers, and it also leads to core dumps on
11760 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11761 A - B only when B is initialized properly.
11762 * coding.c (coding_set_source, coding_set_destination): Return void.
11763 (coding_change_source, coding_change_destinations): New functions,
11764 with the old behaviors of coding_set_source and coding_set_destination.
11765 All callers that need an offset changed to use these new functions.

11782 * w32inevt.c: Include termchar.h and window.h.
11783 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11784 moves, call note_mouse_highlight. If help_echo changed, call
11785 gen_help_event to produce help-echo message in the echo area.
11786 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11789 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11791 * lread.c (read1): Simplify slightly to avoid an overflow warning
11792 with GCC 4.7.0 on x86-64.
11794 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11796 * bidi.c (bidi_mirror_char): Revert last change: an int is
11797 definitely wide enough here.
11799 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

11813 Use int, not EMACS_INT, where int is wide enough.
11814 (inhibit_garbage_collection, Fgarbage_collect):
11815 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11816 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11817 int might not be wide enough.

11833 (Foverlay_recenter, last_overlay_modification_hooks_used)
11834 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11835 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11836 (validate_region): Omit unnecessary test for b <= e,
11837 since that's guaranteed by the previous test.
11838 (adjust_overlays_for_delete): Avoid pos + length overflow.
11839 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11840 (report_overlay_modification):
11841 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11842 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11843 Omit pointer cast, which isn't needed anyway, and doesn't work
11844 after the EMACS_INT -> ptrdiff_t change.
11845 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11846 * buffer.h: Adjust decls to match defn changes elsewhere.
11847 (struct buffer_text, struct buffer):

11850 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11851 not int, to avoid needless 32-bit limit on 64-bit hosts.
11852 (exec_byte_code): Use tighter memory-full test, one that checks
11853 for alloca overflow. Don't compute the address of the object just
11854 before an array, as that's not portable. Use EMACS_INT, not
11855 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11856 * callint.c (Fcall_interactively):
11857 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11858 * callproc.c (call_process_kill, Fcall_process):
11859 Don't assume pid_t fits into an Emacs fixnum.

11868 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11869 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11870 (casify_object): Avoid integer overflow when overallocating buffer.
11871 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11872 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11873 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11874 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11875 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11876 integers are now checked earlier. All uses replaced with XINT.
11878 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11879 For CCL_MapSingle, check that content and value are in int range.
11880 (ccl_driver, Fregister_code_conversion_map):
11881 Check that Vcode_version_map_vector is a vector.
11882 (resolve_symbol_ccl_program): Check that vector header is in range.
11883 Always copy the vector, so that we can check its contents reliably
11884 now rather than having to recheck each instruction as it's being
11885 executed. Check that vector words fit in 'int'.
11886 (ccl_get_compiled_code, Fregister_ccl_program)
11887 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11888 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11889 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11890 contents are in range.
11891 (Fccl_execute_on_string): Check that status is in range.
11892 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11893 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11894 Accept and return EMACS_INT, not int, because callers can pass values
11895 out of 'int' range.

11901 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11902 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11903 avoid mishandling large integers.

11910 Don't assume fixnum fits in int.
11911 (load_charset_map_from_vector, Fmap_charset_chars):
11912 Remove now-unnecessary CHECK_NATNUMs.
11913 (Fdefine_charset_internal): Check ranges here, more carefully.
11914 Don't rely on undefined behavior with signed left shift overflow.
11915 Don't assume unsigned int fits into fixnum, or that fixnum fits
11916 into unsigned int. Don't require max_code to be a valid fixnum;
11917 that's not true for gb10830 4-byte on a 32-bit host. Allow
11918 invalid_code to be a cons, for the same reason. Require code_offset
11919 to be a character. Avoid int overflow if max_char is close
11921 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11922 this is intended anyway and avoids some undefined behavior.
11923 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11924 INDEX_TO_CODE_POINT, as that's what it expects.
11925 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11926 * charset.h (DECODE_CHAR): Return int, not unsigned;
11927 this is what was intended anyway, and it avoids undefined behavior.
11928 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11929 integer-overflow issues.
11930 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11931 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11932 where the argument is EMACS_INT, and this behavior is not intended.
11933 * chartab.c (Fmake_char_table, Fset_char_table_range)
11934 (uniprop_get_decoder, uniprop_get_encoder):
11935 Don't assume fixnum fits in int.
11936 * cmds.c (move_point): New function, that does the gist of
11937 Fforward_char and Fbackward_char, but does so while checking
11938 for integer overflow more accurately.
11939 (Fforward_char, Fbackward_char): Use it.
11940 (Fforward_line, Fend_of_line, internal_self_insert)
11941 (internal_self_insert):
11942 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11943 Fix a FIXME, by checking for integer overflow when calculating

11979 Don't access memory outside of the args array.
11980 (Fdefine_coding_system_internal): Check for charset-id overflow.

12001 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
12002 Do not attempt to compute the address of the object just before a

12723 2012-05-14 Glenn Morris <rgm@gnu.org>

12733 (report_error, report_error_1, make_hdr, copy_sym)
12734 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12735 Make arguments const char *, not char *, to avoid violations of C
12736 standard and to fix some AIX warnings reported by Gilles Pion.
12738 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12740 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12741 already have overlays loaded.
12742 (handle_single_display_spec): Before returning without displaying
12743 fringe bitmap, synchronize the bidi iterator with the main display
12744 iterator, by calling iterate_out_of_display_property.
12745 (iterate_out_of_display_property): Detect buffer iteration by
12746 testing that it->string is a Lisp string.
12747 (get_next_display_element): When the current object is exhausted,
12748 and there's something on it->stack, call set_iterator_to_next to
12749 proceed with what's on the stack, instead of returning zero.
12750 (set_iterator_to_next): If called at the end of a Lisp string,
12751 proceed to consider_string_end without incrementing string
12752 position. Don't increment display vector index past the end of
12753 the display vector. (Bug#11417)
12754 (pos_visible_p): Don't report a position visible when move_it_to
12755 stopped at the last line of window, which happens to be scanned
12756 backwards by the bidi iteration. (Bug#11464)
12758 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12760 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12761 and right-margin display specs even if the spec is invalid or we
12762 are on a TTY, and thus unable to display on the fringes.
12763 That's because the text with the property will not be displayed anyway,
12764 so we need to signal to the caller that this is a "replacing"
12765 display spec. This fixes display when the spec is invalid or we
12768 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12770 * unexaix.c (make_hdr): Fix typo in prototype.

12801 Update dependencies.
12803 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12805 * xgselect.c (xg_select): Put maxfds+1 into a var.
12806 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12808 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12810 2012-05-10 Dave Abrahams <dave@boostpro.com>

12817 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12818 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12819 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12820 Initialize xd_registered_buses.
12822 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12824 Untag more efficiently if USE_LSB_TAG.
12825 This is based on a proposal by YAMAMOTO Mitsuharu in
12826 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12827 For an admittedly artificial (nth 8000 longlist) benchmark on
12828 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12829 Emacs's overall text size by 1%.
12830 * lisp.h (XUNTAG): New macro.
12831 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12832 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12833 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12834 * eval.c (Fautoload):
12835 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12836 * frame.h (XFRAME): Use XUNTAG.
12838 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12839 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12840 Remove unportable assumptions about print widths of types like
12842 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12843 intptr_t when converting between pointer and integer, to avoid GCC
12844 warnings about wrong width.
12846 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12848 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12849 stack for each reader_thread, instead of defaulting to 8MB
12850 determined by the linker. This avoids failures in creating
12851 subprocesses on Windows 7, see the discussion in this thread:
12852 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12854 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12856 Fix up display of the *Minibuf-0* buffer in the mini window.
12857 * keyboard.c (read_char): Don't clear the echo area if there's no
12859 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12860 contents of *Minibuf-0*) if there's no message displayed in its stead.
12862 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12864 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12867 2012-05-06 Chong Yidong <cyd@gnu.org>
12869 * lisp.mk (lisp): Update.
12871 2012-05-05 Jim Meyering <meyering@redhat.com>
12873 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12875 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12877 * data.c (PUT_ERROR): New macro.
12878 (syms_of_data): Use it. Add new error type `user-error'.
12879 * undo.c (user_error): New function.
12880 (Fprimitive_undo): Use it.
12881 * print.c (print_error_message): Adjust print style for `user-error'.
12882 * keyboard.c (user_error): New function.
12883 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12885 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12887 Do not limit current-time-string to years 1000..9999.
12888 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12889 (Fcurrent_time_string): Support any year that is supported by the
12890 underlying localtime representation. Don't use asctime, as it
12891 has undefined behavior for years outside the range -999..9999.
12893 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12895 Fix race conditions involving setenv, gmtime, localtime, asctime.
12896 Without this fix, interrupts could mess up code that uses these
12897 nonreentrant functions, since setting TZ invalidates existing
12898 tm_zone or tzname values, and since most of these functions return
12899 pointers to static storage.
12900 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12901 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12902 Grow the critical sections to include not just invoking
12903 localtime/gmtime, but also accessing these functions' results
12904 including their tm_zone values if any, and any related TZ setting.
12905 (format_time_string): Last arg is now struct tm *, not struct tm **,
12906 so that the struct tm is saved in the critical section.
12907 All callers changed. Simplify allocation of initial buffer, partly
12908 motivated by the fact that memory allocation needs to be outside
12909 the critical section.
12911 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12913 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12914 with RESET_INTERVAL.
12916 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12917 Remove duplicated buffer name initialization.
12919 2012-05-02 Jim Meyering <jim@meyering.net>
12921 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12923 * xfns.c (x_window): Use xstrdup (Bug#11375).
12925 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12927 * xdisp.c (pos_visible_p): If already at a newline from the
12928 display string before the 'while' loop, don't walk back the glyphs
12929 from it3.glyph_row. Solves assertion violation when the display
12930 string begins with a newline (egg.el). (Bug#11367)
12932 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12934 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12937 2012-05-01 Glenn Morris <rgm@gnu.org>
12939 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12940 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12941 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12942 All were removed before 23.1.
12944 * dispnew.c: Remove HAVE_LIBNCURSES test;
12945 it is always true on relevant platforms.
12947 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12948 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12950 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12952 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12954 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12955 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12958 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12960 Do not avoid creating empty evaporating overlays (Bug#9642).
12961 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12962 That is, do not delete an evaporating overlay if it becomes
12963 empty after its bounds are adjusted to fit within its buffer.
12964 This fix caused other problems, and I'm reverting it until we get
12965 to the bottom of them.
12967 2012-04-27 Chong Yidong <cyd@gnu.org>
12969 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12971 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12973 * xdisp.c (pos_visible_p): If the window start position is beyond
12974 ZV, start the display from buffer beginning. Prevents assertion
12975 violation in init_iterator when the minibuffer window is scrolled
12976 via the scroll bar.
12978 * window.c (window_scroll_pixel_based): Likewise.
12980 2012-04-27 Chong Yidong <cyd@gnu.org>
12982 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12984 2012-04-27 Glenn Morris <rgm@gnu.org>
12986 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12987 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12989 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12991 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12992 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12994 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12996 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12997 display element, check also the underlying string or buffer
12998 character. (Bug#11341)
13000 * w32menu.c: Include w32heap.h.
13001 (add_menu_item): If the call to AppendMenuW (via
13002 unicode_append_menu) fails, disable Unicode menus only if we are
13003 running on Windows 9X/Me.
13005 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13007 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13008 (xgetint): Add missing shift for LSB tags.
13010 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13012 * keyboard.c (read_char): Don't wipe echo area for select window
13013 events: These might get delayed via `mouse-autoselect-window'
13016 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13018 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13019 manipulation of :loaded-from data.
13021 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13023 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13024 now a cons (bug#11311).
13026 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13028 Do not create empty overlays with the evaporate property (Bug#9642).
13029 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13030 if it becomes empty after its bounds are adjusted to fit within
13031 its buffer. Without this fix, in a nonempty buffer (let ((o
13032 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13033 yields an empty overlay that has the evaporate property, which is
13034 not supposed to happen.
13036 Fix minor GTK3 problems found by static checking.
13037 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13038 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13039 (struct _EmacsFixedClass, emacs_fixed_get_type):

13042 (emacs_fixed_class_init): Omit unused local.
13043 (emacs_fixed_child_type): Remove; unused.

13045 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13046 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13047 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
13048 (EMACS_FIXED_GET_CLASS): Remove; unused.
13049 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
13051 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
13052 Problem reported by Juanma Barranquero for Windows -Wunused-function.
13054 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13056 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13057 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13058 (__malloc_size_t, __malloc_ptrdiff_t):
13059 Remove. All uses removed, replaced by the definiens if needed,
13060 since we can assume C89 or better now.
13061 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
13062 (protect_malloc_state, align, get_contiguous_space)
13063 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

13068 (special_realloc, _realloc_internal_nolock, _realloc_internal)
13069 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13070 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13071 Define using prototypes, not old style.
13072 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
13073 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

13078 Omit no-longer-needed casts.
13079 (valloc): Use getpagesize, not __getpagesize.
13080 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
13081 (struct hdr): The 'magic' member is now size_t, not unsigned long.
13083 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
13085 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

13119 (Fdbus_send_signal, Fdbus_register_service)
13120 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

13133 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
13134 Do not assume ptrdiff_t is the same width as 'int'.
13136 * alloc.c: Handle unusual debugging option combinations.
13137 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
13138 since the two debugging options are incompatible.
13139 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
13141 (mem_init, mem_insert, mem_insert_fixup):
13142 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

13152 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13153 Use Emacs indenting style more consistently. Avoid some casts.
13154 Use 'double' consistently rather than mixing 'float' and 'double'.
13156 2012-04-21 Eduard Wiebe <usenet@pusto.de>
13158 * sysdep.c (list_system_processes, system_process_attributes):

13193 row, return zero immediately.
13194 (try_cursor_movement): If inside continuation line, don't back up
13195 farther than the first row after the header line, if any.
13196 Don't consider the header-line row as "partially visible", even if
13197 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

13235 New extern decls, to avoid calling undeclared functions.
13236 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13237 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13238 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13239 (NEED_MEM_INSERT): New macro.
13240 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13241 Remove one incorrect comment and fix another.

13244 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
13245 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
13246 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
13247 (r_alloc_sbrk): Now static.
13249 Improve ralloc.c interface checking.

13251 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
13252 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
13253 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
13254 [REL_ALLOC]: ... to here, to check interface.
13255 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
13256 Remove decls. This fixes an "It stinks!".
13258 * alloc.c (which_symbols): Fix alignment issue / type clash.
13260 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13262 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
13263 (struct Lisp_Misc_Any): Likewise.
13264 (struct Lisp_Free): Likewise.
13265 * alloc.c (union aligned_Lisp_Symbol): Define.
13266 (SYMBOL_BLOCK_SIZE, struct symbol_block): Use union
13267 aligned_Lisp_Symbol instead of struct Lisp_Symbol.
13268 (union aligned_Lisp_Misc): Define.
13269 (MARKER_BLOCK_SIZE, struct marker_block): Use union
13270 aligned_Lisp_Misc instead of union Lisp_Misc.
13271 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
13273 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
13275 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
13276 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
13277 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13278 * s/netbsd.h, s/sol2-6.h:
13279 Remove definition of GC_MARK_STACK, since the default now works.
13280 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13281 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
13282 no longer the default.
13283 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13285 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13287 * lread.c (lisp_file_lexically_bound_p):
13288 Fix hang at ";-*-\n" (bug#11238).
13290 2012-04-14 Eli Zaretskii <eliz@gnu.org>
13292 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
13293 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

13302 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
13304 2012-04-13 Reuben Thomas <rrt@sc3d.org>
13306 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
13308 2012-04-11 Daniel Colascione <dancol@dancol.org>
13310 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13311 against is gone. It's better to use vfork now so that when Cygwin
13312 gains a new, working vfork, we use it automatically (bug#10398).
13314 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
13316 * window.c (save_window_save): Obey window-point-insertion-type.

13330 (handle_interrupt): Use it.
13332 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
13334 * w32.c (w32_delayed_load): Record the full path of the library
13335 being loaded (bug#10424).
13337 2012-04-09 Glenn Morris <rgm@gnu.org>
13339 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13340 not just in the obarray, before snarfing them. (Bug#11036)
13342 * Makefile.in ($(leimdir)/leim-list.el):
13343 Pass EMACS rather than BUILT_EMACS.
13345 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
13347 * process.c (make_process):
13348 * process.h: Add integer `gnutls_handshakes_tried' member to
13351 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
13352 Add convenience `GNUTLS_LOG2i' macro.
13354 * gnutls.c (gnutls_log_function2i): Convenience log function.
13355 (emacs_gnutls_read): Use new log functions,
13356 `gnutls_handshakes_tried' process member, and
13357 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13358 attempts per process (connection).
13360 2012-04-09 Chong Yidong <cyd@gnu.org>
13362 * eval.c (Fuser_variable_p, user_variable_p_eh)
13363 (lisp_indirect_variable): Functions deleted.
13364 (Fdefvar): Caller changed.
13366 * callint.c (Finteractive, Fcall_interactively):
13367 * minibuf.c (Fread_variable): Callers changed.
13369 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13371 * xdisp.c (set_cursor_from_row): If the display string appears in
13372 the buffer at position that is closer to point than the position
13373 after the display string, display the cursor on the first glyph of
13374 the display string. Fixes cursor display when a 'display' text
13375 property immediately follows invisible text. (Bug#11094)
13377 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13379 composite.c: use 'double' consistently
13380 * composite.c (get_composition_id): Use 'double' consistently
13381 instead of converting 'float' to 'double' and vice versa; this is
13382 easier to understand and avoids a GCC warning.
13384 2012-04-09 Glenn Morris <rgm@gnu.org>
13386 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13387 preparation for dumping it with emacs. (Bug#4789)
13388 (leimdir): New variable.
13389 ($(leimdir)/leim-list.el): New rule.
13390 (emacs$(EXEEXT)): Depend on leim-list.el.

13393 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
13394 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
13396 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>

13403 * xml.c (init_libxml2_functions) [WINDOWSNT]:
13404 Remove unused local variable.
13406 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
13408 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
13409 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13410 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13411 objects, as mark_maybe_pointer will catch them otherwise.
13412 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13413 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

13420 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13422 Support building on MS-Windows with libxml2.
13424 * makefile.w32-in (OBJ2): Add xml.$(O).
13425 (GLOBAL_SOURCES): Add xml.c.
13426 ($(BLD)/xml.$(O)): New dependency list.
13428 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
13429 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13430 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13431 [!WINDOWSNT]: New macros.
13432 (init_libxml2_functions, libxml2_loaded_p): New functions.
13433 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13434 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13435 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13436 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13438 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13439 Call init_libxml2_functions before calling libxml2 functions.
13440 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13442 * emacs.c: Don't include libxml/parser.h.
13443 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13444 xmlCleanupParser directly.
13446 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13448 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13450 * indent.c (Fvertical_motion): If there is a display string at
13451 point, use it.vpos to compute how many lines to backtrack after
13452 move_it_to point. (Bug#11133)
13454 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13456 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13457 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13458 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13459 macros related to unification of CJK characters. For the details,
13460 see the discussion following the message here:
13461 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13463 2012-04-04 Chong Yidong <cyd@gnu.org>
13465 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13467 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13469 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13470 instead of alloca. (Bug#11138)
13472 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13474 * w32menu.c (is_simple_dialog): Properly check lisp types.
13477 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13479 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13480 position we get to after a call to move_it_to fails the
13481 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13482 only if we wind up in a string from display property. (Bug#11063)
13484 * window.c (Fdelete_other_windows_internal): Invalidate the row
13485 and column information about mouse highlight, so that redisplay
13486 restores it after reallocating the glyph matrices. (Bug#7464)
13488 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13489 string comes from a `display' text property, use the buffer
13490 position of that property as if we actually saw that position in
13492 (move_it_by_lines): Remove the assertion that
13493 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13494 violated when there's a before-string at the beginning of a line.
13497 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13499 * xdisp.c (append_space_for_newline): If the default face was
13500 remapped, use the remapped face for the appended newline.
13501 (extend_face_to_end_of_line): Use the remapped default face for
13502 extending the face to the end of the line.
13503 (display_line): Call extend_face_to_end_of_line when the default
13504 face was remapped. (Bug#11068)
13506 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13508 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13510 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13512 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13514 2012-03-27 Glenn Morris <rgm@gnu.org>
13516 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13519 2012-03-26 Kenichi Handa <handa@m17n.org>
13521 * dispextern.h (struct glyph): Fix previous change. Change the
13522 bit length of glyphless.ch to 25 (Bug#11082).
13524 2012-03-26 Chong Yidong <cyd@gnu.org>
13526 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13527 (command_loop_1): Use it; inhibit selection update for
13528 handle-select-window too (Bug#8996).
13530 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13532 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13534 2012-03-25 Kenichi Handa <handa@m17n.org>
13536 * dispextern.h (struct glyph): Change the bit length of
13537 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13539 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13541 * s/ms-w32.h (tzname): Include time.h before redirecting to
13542 _tzname. Fixes the MSVC build. (Bug#9960)
13544 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13546 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13549 * xterm.c (XTread_socket): Only modify handling_signal if
13550 !SYNC_INPUT. (Bug#11080)
13552 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13554 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13555 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13556 when fetching a multibyte character consumes more bytes than
13557 CHAR_BYTES returns, due to unification of CJK characters in
13558 string_char. (Bug#11073)
13560 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13562 * process.c (wait_reading_process_output): Handle pty disconnect
13563 by refraining from sending oneself a SIGCHLD (bug#10933).
13565 2012-03-22 Chong Yidong <cyd@gnu.org>
13567 * dispextern.h (struct it): New member string_from_prefix_prop_p.
13569 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
13570 Mark string as coming from a prefix property.
13571 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13572 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.

13576 * xfaces.c (Vface_remapping_alist): Doc fix.
13578 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13580 * w32proc.c (Fw32_set_console_codepage)
13581 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13584 2012-03-20 Chong Yidong <cyd@gnu.org>
13586 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13587 to reflect default non-nil value of redisplay-dont-pause.

13592 it fit in a valid range (Bug#11003).
13594 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13596 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13597 that is not from display property, accept the row as a "cursor
13598 row" if one of the string's character has a non-nil `cursor'
13599 property. Fixes cursor positioning when there are newlines in
13600 overlay strings, e.g. in icomplete.el. (Bug#11035)
13602 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13604 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13606 2012-03-12 Chong Yidong <cyd@gnu.org>
13608 * eval.c (inhibit_lisp_code): Rename from
13609 inhibit_window_configuration_change_hook; move from window.c.
13611 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13612 * window.c (run_window_configuration_change_hook)
13613 (syms_of_window): Callers changed.
13615 2012-03-11 Chong Yidong <cyd@gnu.org>
13617 * keymap.c (Fkey_description): Doc fix (Bug#9700).
13619 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
13621 2012-03-10 Chong Yidong <cyd@gnu.org>
13623 * frame.c (other_visible_frames): Don't assume the selected frame
13624 is visible (Bug#10955).
13626 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13628 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13630 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13632 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13633 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13636 2012-03-03 Glenn Morris <rgm@gnu.org>
13638 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13640 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13642 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13643 position past the first glyph_row that ends at ZV. (Bug#10902)
13644 (redisplay_window, next_element_from_string): Fix typos in
13646 (redisplay_window): Pass to move_it_vertically the margin in
13647 pixels, not in screen lines.
13649 2012-03-02 Glenn Morris <rgm@gnu.org>
13651 * buffer.c (buffer-list-update-hook): Doc fix.
13653 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13655 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13656 push_it before setting up the iterator for the first overlay
13657 string, even if we have an empty string loaded.
13658 (next_overlay_string): If there's an empty string on the iterator
13659 stack, pop the stack. (Bug#10903)
13661 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13663 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13664 Suggested by Stefan Monnier in
13665 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13666 * alloc.c (widen_to_Lisp_Object): New static function.
13667 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13668 and widening them to Lisp_Objects. This would work even if
13669 USE_LSB_TAG is defined and wide integers are used, which might
13670 happen in a future version of Emacs.
13672 2012-02-25 Chong Yidong <cyd@gnu.org>
13674 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13677 * xselect.c (Fx_selection_exists_p): Doc fix.
13678 (x_clipboard_manager_save_all): Print an informative message
13679 before saving to clipboard manager.
13681 2012-02-24 Chong Yidong <cyd@gnu.org>
13683 * keyboard.c (process_special_events): Handle all X selection
13684 requests in kbd_buffer, not just the next one (Bug#8869).
13686 2012-02-23 Chong Yidong <cyd@gnu.org>
13688 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13689 call when setting menu-bar-lines and tool-bar-lines parameters.
13690 (unwind_create_frame_1): New helper function.
13692 * window.c (inhibit_window_configuration_change_hook): New var.
13693 (run_window_configuration_change_hook): Obey it.

13711 when computing $valmask.
13713 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13714 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13715 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13716 It's useless in that case, and it can cause problems on hosts

14340 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
14341 verifies glyph row's hash code--we have just reallocated the

14507 is set, removing the need for VIRT_ADDRESS_VARIES.
14508 (PURE_P): Use a more-efficient implementation that needs just one

14525 behave as if the cursor position were at the window margin.
14527 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14528 and the cursor position is out of bounds, behave as if the cursor
14529 position were at the window margin. (Bug#10075)
14531 2011-11-18 Chong Yidong <cyd@gnu.org>
14533 * window.c (Fwindow_combination_limit): Make first argument

14555 compute_line_metrics.
14556 (compute_line_metrics): Call row_hash, instead of computing the
14559 * dispnew.c (verify_row_hash): Call row_hash for computing the
14560 hash code of a row, instead of duplicating code from xdisp.c.
14562 * dispextern.h (row_hash): Add prototype.
14564 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14566 * frame.c (delete_frame): Don't delete the terminal when the last

14615 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14616 with user-defined heap size. Bump the default size of the temacs

14721 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
14722 This is also needed for porting to any host where GC_MARK_STACK is
14723 not GC_MAKE_GCPROS_NOOPS.
14724 (which_symbols): Use it.
14726 2011-11-07 Kenichi Handa <handa@m17n.org>

14739 * xmenu.c (cleanup_widget_value_tree): New function.
14740 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

14747 (window_box_width, window_box_left, window_box_left_offset)
14748 (window_box_right, window_box_right_offset): Declare extern.
14749 Otherwise, these inline functions do not conform to C99 and
14750 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14751 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14752 * intervals.c (adjust_intervals_for_insertion)
14753 (adjust_intervals_for_deletion): Now extern, because otherwise the

14755 (static_offset_intervals): Remove.
14756 (offset_intervals): Rewrite using the old contents of
14757 static_offset_intervals. The old version didn't conform to C99
14758 because an extern inline function contained a reference to an
14759 identifier with static linkage.

14783 argument, since it makes no sense to pass a live window and for
14784 consistency with window-child.

14825 official. Move initialization of image_cache_refcount and
14826 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

14994 (w32font_open_internal, compute_metrics):
14995 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w

15071 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15072 * editfns.c: Rewrite current-time-zone so that it invokes
15073 the equivalent of (format-time-string "%Z") to get the time zone name.
15074 This fixes a bug when the time zone name contains characters that
15075 need converting from the system time locale to Emacs internal format.
15076 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15077 that patch fixed format-time-string to do the conversion, but
15078 I forgot to fix current-time-zone.
15079 (format_time_string): New function, containing most of
15080 what Fformat_time_string used to contain.
15081 (Fformat_time_string): Rewrite in terms of format_time_string.
15082 This doesn't change this function's behavior.
15083 (current-time-zone): Rewrite to use format_time_string.
15084 This fixes the bug reported by Michael Schierl in
15085 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15086 Jason Rumney's 2007-06-07 change worked around this bug, but
15088 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15090 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15092 * xdisp.c (start_display): If the character at POS is displayed
15093 via a display vector, reset IT->current.dpvec_index to zero.
15094 (try_window_reusing_current_matrix): If a line ends in a display
15095 vector or the next line starts in a display vector, continue
15096 redrawing the window even though the character position of
15097 start_row was reached.
15100 2011-10-18 Chong Yidong <cyd@gnu.org>
15102 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15103 with nobreak-char-display too.
15105 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15107 Fix part 3 of bug#9771.
15108 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15109 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15110 non-neutral characters if the current character is a paragraph
15111 separator (a.k.a. Newline). This avoids running the same
15112 expensive loop twice, once when we consume the preceding newline
15113 and the other time when the line actually needs to be displayed.
15114 Avoid the loop when we see neutrals on the base embedding level
15115 following a character whose directionality is the same as the
15116 paragraph's. This avoids running the expensive loop when a line
15117 ends in a long sequence of neutrals, like control characters.
15118 Add assertion against STRONG_AL type. Slightly rearrange code
15119 that determines the type of a neutral given the first non-neutral
15121 (bidi_level_of_next_char): Set next_en_pos to zero when
15122 invalidating its info.
15124 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15126 * xdisp.c (push_display_prop): Determine whether to record string
15127 or buffer position by IT->string, not by IT->method. Allow
15128 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15129 (move_it_vertically_backward): Don't look for character position
15130 immediately after the newline when in a continuation line.
15133 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15135 * window.c (coordinates_in_window): Rewrite and delabelize
15136 vertical border check. (Bug#5357) (Bug#9618)
15138 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15140 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15141 errors in XSetWindowBorder (bug#9310).
15143 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15145 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15146 avoid crash when xmalloc overrun checking is enabled.
15148 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15150 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15151 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15152 cursor motion with <left> and <right> arrow keys.
15154 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15155 some callers set that themselves.
15157 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15159 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15160 display string and the previous row comes from the same string and
15161 is empty. (Bug#9739) (Bug#9738)
15163 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15165 * doc.c (get_doc_string): Encode file name (bug#9735).
15167 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15169 * bidi.c (bidi_level_of_next_char):
15170 * xdisp.c (get_visually_first_element): Remove old incorrect
15171 comments regarding the Unicode Line Separator character.
15173 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15175 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15177 * alloc.c (Fgc_status): Do not access beyond zombies array
15178 boundary if nzombies > MAX_ZOMBIES.
15179 * alloc.c (dump_zombies): Add missing format specifier.
15181 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15183 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15184 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15186 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15187 Some packages use them to denote characters with modifiers.
15189 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15191 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15192 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15193 matching a pp-number. Rename parameter var to var1.
15195 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15197 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15199 2011-10-08 Glenn Morris <rgm@gnu.org>
15201 * callint.c (Fcall_interactively): Give a more explicit error for the
15202 'c' case with a non-character input. (Bug#8479)
15204 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15206 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15208 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15209 lines that are hscrolled on the left.
15211 * dispnew.c (buffer_posn_from_coords): Account for a possible
15212 presence of header-line. (Bug#4426)
15214 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15216 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15217 Don't advertise functionality which we discourage or doesn't work.
15219 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15221 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15222 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15223 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15224 this makes Emacs dump core during garbage collection on rare
15225 occasions. sizeof is obviously inferior to offsetof here, so
15226 stick with offsetof.
15227 (GC_POINTER_ALIGNMENT): New macro.
15228 (mark_memory): Omit 3rd (offset) arg; caller changed.
15229 Don't assume EMACS_INT alignment is the same as pointer alignment.
15231 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15233 * keyboard.c (read_key_sequence_remapped): New var.
15234 (read_key_sequence): Compute remapping in the right buffer.
15235 (command_loop_1): Use read_key_sequence's remapping directly.
15237 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15239 * dired.c (file_name_completion): Don't expand file name.
15240 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15241 before checking file name handler.
15243 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15244 they've been requested explicitly (bug#9591).
15246 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15248 * keymap.c (Fsingle_key_description): Use make_specified_string
15249 instead of build_string to build string from push_key_description.
15252 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15254 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15255 This fixes a Y2038 bug on 64-bit hosts.
15256 * buffer.c (reset_buffer):
15257 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15258 (Fclear_buffer_auto_save_failure):
15259 Use 0, not -1, to represent an unset failure time, since time_t
15260 might not be signed.
15262 Remove dependency on glibc malloc internals.
15263 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15264 Move back here from lisp.h, but with their new implementations.
15265 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15266 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15267 * charset.c (charset_table_init): New static var.
15268 (syms_of_charset): Use it instead of xmalloc. This removes a
15269 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15270 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15271 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15272 Move back to alloc.c.
15273 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15274 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15276 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15278 * nsterm.m (windowDidResize): Call x_set_window_size only when
15279 ns_in_resize is true. Otherwise set pixelwidth/height and
15280 call change_frame_size (Bug#9628).
15282 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15284 Port --enable-checking=all to Fedora 14 x86-64.
15285 * charset.c (syms_of_charset): Also account for glibc malloc's
15286 internal overhead when calculating the initial malloc maximum.
15288 Port --enable-checking=all to Fedora 14 x86.
15289 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15291 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15292 (overrun_check_realloc, overrun_check_free):
15293 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15294 That way, xmalloc returns a properly-aligned pointer even if
15295 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15296 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15297 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15298 into account when calculating the initial malloc maximum.
15299 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15300 Move here from alloc.c, so that charset.c can use it too.
15301 Properly align; the old code wasn't right for common 32-bit hosts
15302 when configured with --enable-checking=all.
15303 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15304 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15306 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15308 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15311 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15313 * xdisp.c (compute_display_string_end): If there's no display
15314 string at CHARPOS, return -1.
15316 * bidi.c (bidi_fetch_char): When compute_display_string_end
15317 returns a negative value, treat the character as a normal
15318 character not covered by a display string. (Bug#9624)
15320 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15322 * lread.c (Fread_from_string): Fix typo in docstring.
15324 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15326 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15327 newline, reseat the iterator instead of bidi-iterating there one
15328 character at a time. (Bug#9610)
15329 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15330 TO_CHARPOS if the bidi iterator is at base embedding level.
15332 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15334 * lread.c (readevalloop): Use correct code for NBSP.
15335 (read1): Likewise. (Bug#9608)
15337 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15339 * dbusbind.c (Fdbus_register_signal): When service is not
15340 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15342 2011-09-25 Glenn Morris <rgm@gnu.org>
15344 * buffer.c (truncate-lines): Doc fix.
15346 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15348 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15349 (Fset_window_next_buffers): Doc fix.
15351 2011-09-24 Glenn Morris <rgm@gnu.org>
15353 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15355 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15357 Fix minor problems found by static checking.
15358 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15359 * indent.c (Fvertical_motion): Fix == vs = typo.
15361 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15363 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15364 Default value is now t. Doc fix.
15366 * indent.c (Fvertical_motion): Compute and apply the overshoot
15367 logic when moving up, not only when moving down. Fix the
15368 confusing name and values of the it_overshoot_expected variable;
15369 logic changes accordingly. (Bug#9254) (Bug#9549)
15371 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15372 CHARPOS is covered by a display string which includes newlines.
15373 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15374 is covered by a display string with embedded newlines.
15376 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15378 * dbusbind.c (Fdbus_register_signal): Add match rule to
15379 Vdbus_registered_objects_table. (Bug#9581)
15380 (Fdbus_register_method, Vdbus_registered_objects_table):
15383 2011-09-24 Jim Meyering <meyering@redhat.com>
15385 do not ignore write error for any output size
15386 The previous change was incomplete.
15387 While it makes emacs --batch detect the vast majority of stdout
15388 write failures, errors were still ignored whenever the output size is
15389 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15390 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15391 && echo FAIL: ignored write error
15392 FAIL: ignored write error
15393 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15394 && echo FAIL: ignored write error
15395 FAIL: ignored write error
15396 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15398 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15400 * emacs.c (Fkill_emacs): In noninteractive mode exit
15401 non-successfully if a write error occurred on stdout. (Bug#9574)
15403 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15405 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15408 * dispextern.h (struct it): Update the comment documenting what
15411 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15413 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15414 a display string, extend search for cursor position to end of row.
15415 (find_row_edges): If the row ends in a newline from a display
15416 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15417 Handle the case of a display string with multiple newlines.
15418 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15419 non-empty line. Fixes confusing cursor motion with arrow keys at
15420 the beginning of a line that starts with whitespace.
15422 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15424 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15427 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15429 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15430 boolean (Bug#9154).
15432 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15434 * xdisp.c (display_line): Record maximum and minimum buffer
15435 positions even if no glyphs were produced (e.g., by a zero-width
15436 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15437 buffer positions that will be removed from the glyph row because
15439 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15440 column is beyond frame width: don't subtract 1 "pixel" when
15441 computing width of the stretch.
15442 (reseat_at_next_visible_line_start): Undo the change made on
15443 2011-09-17 that saved paragraph information and restored it after
15444 the call to `reseat'. (Bug#9545)
15446 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15448 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15449 and turn window cursor on if cleared (Bug#9415).
15451 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15453 * search.c (boyer_moore): Take unibyte characters from pattern
15454 literally. (Bug#9458)
15456 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15458 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15460 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15462 Fix minor problem found by static checking.
15463 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15464 initialized, to pacify gcc -Wuninitialized.
15466 * fileio.c: Report proper errno when syscall falls.
15467 (Finsert_file_contents): Save and restore errno,
15468 so that report_file_error outputs the correct diagnostic.
15469 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15471 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15473 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15475 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15477 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15478 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15480 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15482 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15483 about the current paragraph and restore it after the call to reseat.
15485 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15486 (bidi_find_paragraph_start): Search back for paragraph beginning
15487 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15488 (bidi_move_to_visually_next): Only trigger paragraph-related
15489 computations when the last character is a newline or at EOB, not
15490 just any NEUTRAL_B. (Bug#9470)
15492 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15493 truncated lines if point is covered by a display string. (Bug#9524)
15495 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15497 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15498 (cons_to_x_long): New function.
15499 (lisp_data_to_selection_data): Use it. Correct the test for
15500 short-versus-long data; it was negated. Break out of vector
15501 loop, for efficiency, when a long datum is discovered.
15503 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15505 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15507 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15509 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15510 GCC PR/17406) by declaring this function with external scope.
15512 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15514 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

15519 * editfns.c (Fformat): Correctly handle text properties on "%%".
15521 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15523 * xterm.c (x_draw_composite_glyph_string_foreground):
15524 * w32term.c (x_draw_composite_glyph_string_foreground):
15525 * term.c (encode_terminal_code):
15526 * composite.c (composition_update_it, get_composition_id):
15527 * xdisp.c (get_next_display_element)
15528 (fill_composite_glyph_string): Add comments about special meaning
15529 of TAB characters in a composition.
15531 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15533 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15534 This occurs when processing a multibyte format.
15535 Problem reported by Wolfgang Jenker.
15537 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15539 * xdisp.c (try_cursor_movement): Only check for exact match if
15540 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15542 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15544 Remove unused external symbols.
15545 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15546 * xdisp.c (calc_pixel_width_or_height): Now static.
15547 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.

15550 * xterm.c, xterm.h (x_catching_errors): Remove.
15552 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15554 * xselect.c: Use signed conversions more consistently (Bug#9498).
15555 (selection_data_to_lisp_data): Assume incoming selection data are
15556 signed integers, not unsigned. This is to be consistent with
15557 outgoing selection data, which was modified to use signed integers
15558 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15559 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15560 expects long, not unsigned long.

15564 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15565 computation of loop end. Reported by Johan Bockgård
15568 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15570 * frame.c (Fother_visible_frames_p): Function deleted.
15572 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15574 * indent.c (compute_motion): Process display vector front to back
15575 rather than the other way around. (Bug#2496)
15577 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15579 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15581 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15583 * minibuf.c (Fread_from_minibuffer): Doc fix.
15585 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15587 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15588 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15590 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15592 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15593 value for non-existent files.
15595 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15597 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15598 set its "size" to -1. This will set the modtime_size field of
15599 the corresponding buffer to -1, which is what
15600 verify-visited-file-modtime expects for files that do not exist.
15603 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15605 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15607 * lisp.h: ... from here. push_key_description is no longer
15608 defined in keyboard.c, so its declaration should not be in
15609 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15610 logically belongs with push_key_description.
15612 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15614 * buffer.h: Include <sys/types.h> instead of <time.h>.
15615 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15616 Problem reported by Herbert J. Skuhra.
15618 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15620 * xml.c (parse_region): Make the parsing work for
15621 non-comment-starting XML files again (bug#9144).
15623 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15625 * image.c (gif_load): Fix calculation of bottom and right corner.
15628 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15630 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15631 redisplay in small windows.
15633 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15635 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15637 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15639 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15640 Operate on live windows only.
15642 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15644 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15646 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15648 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15649 only under bidi iteration.
15651 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15653 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15655 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15657 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15658 Without this fix, the command to link temacs failed due to an
15659 undefined symbol __builtin_isnan. This is because
15660 /usr/include/iso/math_c99.h #defines isnan(x) to
15661 __builtin_isnan(x), but the bundled gcc, which identifies itself
15662 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15664 * floatfns.c (isnan): #undef, and then #define to a clone of
15666 (Fisnan): Always define, since it's always available now.
15667 (syms_of_floatfns): Always define isnan at the Lisp level.
15669 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15671 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15673 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15675 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15676 The previous code assumed that file offsets (off_t values) fit in
15677 EMACS_INT variables, which is not true on typical 32-bit hosts.
15678 The code messed up by falsely reporting buffer overflow in cases
15679 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15680 when "big" contains more than 2**29 bytes, even though this
15681 inserts just one byte and does not overflow the buffer.
15682 (Finsert_file_contents): Store file offsets as off_t
15683 values, not as EMACS_INT values. Check for overflow when
15684 converting between EMACS_INT and off_t. When checking for
15685 buffer overflow or for overlap, take the offsets into account.
15686 Don't use EMACS_INT for small values where int suffices.
15687 When checking for overlap, fix a typo: ZV was used where
15688 ZV_BYTE was intended.
15689 (Fwrite_region): Don't assume off_t fits into 'long'.
15690 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15692 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15694 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15696 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15698 sprintf-related integer and memory overflow issues (Bug#9412).
15700 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15701 (esprintf, exprintf, evxprintf): New functions.
15702 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15703 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15704 (modify_event_symbol): Do not assume that the length of
15705 name_alist_or_stem is safe to alloca and fits in int.
15706 (Fexecute_extended_command): Likewise for function name and binding.
15707 (Frecursion_depth): Wrap around reliably on integer overflow.
15708 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15709 since some callers pass EMACS_INT values.
15710 (Fsingle_key_description): Don't crash if symbol name contains more
15711 than MAX_ALLOCA bytes.
15712 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15713 (get_minibuffer): Arg is now EMACS_INT, not int.
15714 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15715 (esprintf, exprintf, evxprintf): New decls.
15716 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15718 * dbusbind.c (signature_cat): New function.
15719 (xd_signature, Fdbus_register_signal):
15720 Do not overrun buffer; instead, report string overflow.
15722 * dispnew.c (add_window_display_history): Don't overrun buffer.
15723 Truncate instead; this is OK since it's just a log.
15725 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15726 even if the time zone offset is outlandishly large.
15727 Don't mishandle offset == INT_MIN.
15729 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15730 when creating daemon; the previous buffer-overflow check was incorrect.
15732 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15733 which has the guts of the old verror function.
15735 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15736 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15738 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15739 (font_unparse_xlfd): Don't blindly alloca long strings.
15740 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15741 fits in int, when using sprintf. Use single snprintf to count
15742 length of string rather than counting it via multiple sprintfs;
15743 that's simpler and more reliable.
15744 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15745 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15746 sprintf, in case result does not fit in int.
15748 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15749 (fontset_from_font): Print it.
15751 * frame.c (tty_frame_count): Now printmax_t, not int.
15752 (make_terminal_frame, set_term_frame_name): Print it.
15753 (x_report_frame_params): In X, window IDs are unsigned long,
15754 not signed long, so print them as unsigned.
15755 (validate_x_resource_name): Check for implausibly long names,
15756 and don't assume name length fits in 'int'.
15757 (x_get_resource_string): Don't blindly alloca invocation name;
15758 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15761 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15762 (xg_check_special_colors, xg_set_geometry):
15763 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15765 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15766 Use esprintf, not sprintf, in case result does not fit in int.
15768 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15769 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15770 it as a large positive number.
15771 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15772 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15774 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15775 in case result does not fit in int.
15777 * print.c (float_to_string): Detect width overflow more reliably.
15778 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15779 buffer overrun. Don't assume list length fits in 'int'. Treat
15780 print length of 0 as 0, not as infinity; to be consistent with other
15781 uses of print length in this function. Don't overflow print length
15782 index. Don't assume hash table size fits in 'long', or that
15783 vectorlike size fits in 'unsigned long'.
15785 * process.c (make_process): Use printmax_t, not int, to format
15786 process-name gensyms.
15788 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15790 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15791 to avoid potential buffer overrun.
15793 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15794 if X resource line is longer than 512 bytes.
15796 * xfns.c (x_window): Make sprintf buffer a bit bigger
15797 to avoid potential buffer overrun.
15799 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15801 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15803 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15805 Integer overflow fixes for scrolling, etc.
15806 Without these, Emacs silently mishandles large integers sometimes.
15807 For example, "C-u 4294967297 M-x recenter" was treated as if
15808 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15810 * xdisp.c (try_window_id): Check Emacs fixnum range before
15811 converting to 'int'.
15813 * window.c (window_scroll_line_based, Frecenter):
15814 Check that an Emacs fixnum is in range before assigning it to 'int'.
15815 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15816 values converted from Emacs fixnums.
15817 (Frecenter): Don't wrap around a line count if it is out of 'int'
15818 range; instead, treat it as an extreme value.
15819 (Fset_window_configuration, compare_window_configurations):
15820 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15822 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15823 that can exceed INT_MAX. Check that EMACS_INT value is in range
15824 before assigning it to the (possibly-narrower) index.
15825 (match_limit): Don't assume that a fixnum can fit in 'int'.
15827 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15830 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15831 (Fvertical_motion): Don't wrap around LINES values that don't fit
15832 in 'int'. Instead, treat them as extreme values. This is good
15833 enough for windows, which can't have more than INT_MAX lines anyway.
15835 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15837 * Require libxml/parser.h to avoid compilation warning.
15839 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15841 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15842 since this reportedly can destroy thread storage.
15844 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15846 * syntax.c (find_defun_start): Update all cache variables if
15847 exiting early (Bug#9401).
15849 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15851 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15853 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15854 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15855 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15857 * term.c (tty_append_glyph): New function.
15858 (produce_stretch_glyph): Static function and its prototype deleted.
15860 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15863 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15865 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15866 when checking :margin (Bug#9390).
15867 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15868 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15869 so that the name doesn't mislead. All uses changed.
15871 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15873 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15876 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15878 * xdisp.c (move_it_to): Don't bail out early when reaching
15879 position beyond to_charpos, if we are scanning backwards.
15880 (move_it_vertically_backward): When DY == 0, make sure we get to
15881 the first character in the line after the newline.
15883 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15885 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15886 (ccl_driver): Do not generate an out-of-range pointer.
15887 (Fccl_execute_on_string): Remove unnecessary check for
15888 integer overflow, noted by Stefan Monnier in
15889 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15890 Remove a FIXME that didn't need fixing.
15891 Simplify the newly-introduced buffer reallocation code.
15893 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15895 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15897 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15899 Integer and memory overflow issues (Bug#9196).
15901 * doc.c (get_doc_string): Rework so that
15902 get_doc_string_buffer_size is the actual buffer size, rather than
15903 being 1 less than the actual buffer size; this makes xpalloc more
15906 * image.c (x_allocate_bitmap_record, cache_image):
15907 * xselect.c (Fx_register_dnd_atom):
15908 Simplify previous changes by using xpalloc.
15910 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15911 since either will do and ptrdiff_t is convenient with xpalloc.
15913 * charset.c (charset_table_size)
15914 (struct charset_sort_data.priority): Now ptrdiff_t.
15915 (charset_compare): Don't overflow if priorities differ greatly.
15916 (Fsort_charsets): Don't assume list length fits in int.
15917 Check for size-calculation overflow when allocating sort data.
15918 (syms_of_charset): Allocate an initial charset table that is
15919 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15921 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15923 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15924 The actual value is always <= INT_MAX, and leaving it unsigned made
15925 overflow checking harder.
15927 * dispextern.h (struct glyph_matrix.rows_allocated)
15928 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15929 with xpalloc. The values are still always <= INT_MAX.
15931 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15933 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15934 (SAFE_NALLOCA): New macro.
15936 * region-cache.c (struct boundary.pos, find_cache_boundary)
15937 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15938 (set_cache_region, invalidate_region_cache)
15939 (revalidate_region_cache, know_region_cache, region_cache_forward)
15940 (region_cache_backward, pp_cache):
15941 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15942 so that ptrdiff_t * can be passed to xpalloc.
15943 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15944 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15945 (pp_cache): Don't assume cache_len fits in int.
15946 * region-cache.h: Adjust extern decls to match.
15948 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15949 EMACS_INT, since either will do, for xpalloc.
15951 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15952 (xnmalloc, xnrealloc, xpalloc): New functions.
15954 * bidi.c (bidi_shelve_header_size): New constant.
15955 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15956 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15958 * bidi.c (bidi_cache_shrink):
15959 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15961 Don't update size of array until after memory allocation succeeds,
15962 because xmalloc/xrealloc may not return.
15963 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15964 now that we have proper integer overflow checking.
15965 (record_overlay_string, overlay_strings): Catch overflows when
15966 calculating size of overlay_str_buf.
15968 * callproc.c (Fcall_process): Check for size overflow when
15969 calculating size of args2.
15970 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15971 Normally we prefer signed values, but sticking with ptrdiff_t would
15972 require adding more-complicated checks.
15974 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15975 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15976 Redo buffer-overflow calculations to avoid integer overflow.
15977 Add a FIXME comment where memory seems to be over-allocated.
15979 * character.c (Fstring): Check for size-calculation overflow.
15981 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15982 unnecessary integer overflow. Check for size overflow.
15983 (encode_coding_object): Don't update size until xmalloc succeeds.
15985 * composite.c (get_composition_id): Check for overflow in glyph
15986 length calculations.
15988 Integer and memory overflow fixes for display code.
15989 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15990 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15991 (scrolling_window): Check for overflow in size calculations.
15992 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15993 Don't assume glyph table len fits in int.
15994 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
15995 (row_table_size): Now ptrdiff_t, not int.
15996 (scrolling_window): Avoid overflow in size calculations.
15997 Don't update size until allocation succeeds.
15998 * fns.c (concat): Check for overflow in size calculations.
15999 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16000 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
16001 (NEXT_ALMOST_PRIME_LIMIT): New constant.
16003 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16004 (get_doc_string): Check for size calculation overflow.
16005 Don't update size until allocation succeeds.
16006 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16007 EMACS_INT, where ptrdiff_t will do.
16008 (Fsubstitute_command_keys): Check for string overflow.
16010 * editfns.c (set_time_zone_rule): Don't assume environment length
16012 (message_length): Now ptrdiff_t, not int.
16013 (Fmessage_box): Don't update size until allocation succeeds.
16014 Don't assume message length fits in int.
16015 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16017 * emacs.c (main): Do not reallocate argv, since there is a null at
16018 the end that can be overwritten, and this way there's no need to
16019 worry about size-calculation overflow.
16020 (sort_args): Check for size-calculation overflow.

16028 Check for integer overflow.
16029 (x_set_alpha): Do not assume XINT fits in int.
16031 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16032 This is for the members text_lines, text_cols, total_lines, total_cols,
16033 where the system imposes an 'int' limit.
16035 * fringe.c (Fdefine_fringe_bitmap):

16042 Check for size-calculation overflow.
16043 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16044 do, as we prefer signed integers.

16100 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16101 for command line length. Do not attempt to address one before the
16102 beginning of an array, as that's not portable.

16132 Check for size calculation overflow.
16133 (cache_face): Treat size calculation overflows as if they were
16134 memory exhaustion (the usual treatment), rather than aborting.
16136 * xfns.c (x_encode_text, x_set_name_internal)
16137 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16138 sizes, since they can exceed INT_MAX in size. Check for size
16139 calculation overflow.

16142 (xg_select): Check for size calculation overflow.
16143 Don't update size until alloc done.
16145 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16146 as sprintf is limited to int lengths.
16148 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16149 (X_LONG_MIN): New macros.
16150 Use them to make the following changes clearer.
16151 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16152 This change doesn't affect the value now, but it may help remind
16153 future maintainers not to raise the value too much later.
16154 (SELECTION_QUANTUM): Remove, replacing with ...
16155 (selection_quantum): ... new function, which avoids overflow.
16157 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16158 assumption that selection length fits in 'int'.

16175 Don't store size until memory allocation succeeds.
16176 (x_get_window_property): Plug memory leak on memory exhaustion.
16177 Don't double-block input; malloc is safe here. Don't assume 2**34
16178 - 4 fits in unsigned long. Add an xassert to check
16179 XGetWindowProperty overflow. Be more careful about overflow
16180 calculations, and distinguish size from memory overflow better.
16181 (receive_incremental_selection): When tracing, don't assume
16182 unsigned int is less than INT_MAX.
16183 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

16186 in the range -65535 through -1 fit in an X unsigned short.
16187 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16188 result parameters unless successful. Rely on cons_to_unsigned
16189 to report problems with elements; the old code wasn't right anyway.
16190 (x_check_property_data): Check for int overflow; we cannot use
16191 a wider type due to X limits.
16192 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

16224 * lisp.h (hash_lookup, hash_put):
16225 * minibuf.c (Ftest_completion):
16226 Use ptrdiff_t for hash table indexes, not int (which is too
16227 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16228 32-bit --with-wide-int hosts).
16230 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16231 Add a FIXME comment about memory leaks.
16232 (syms_of_charset): Don't assume xmalloc returns.

16239 with outlandish widths.
16240 * character.h (sanitize_tab_width): Rename from sanitize_width,
16241 now that we have two such functions. All uses changed.

16259 * xterm.c: Don't go over XClientMessageEvent limit.
16260 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16261 (x_send_scroll_bar_event): Likewise. Check that the size does not
16262 exceed limits imposed by XClientMessageEvent, as well as the usual
16263 ptrdiff_t and size_t limits.
16265 * keyboard.c: Overflow, signedness and related fixes.
16266 (make_lispy_movement): Use same integer type in forward decl
16267 that is used in the definition.
16268 (read_key_sequence, keyremap_step):
16269 Change bufsize argument back to int, undoing my 2011-03-30 change.
16270 We prefer signed types, and int is wide enough here.
16271 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16272 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16273 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16274 length, not size_t. Use ptrdiff_t for index, not int.
16275 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16276 possibility of integer overflow.
16278 Overflow, signedness and related fixes for images.

16304 Prefer int to unsigned where either will do.
16305 (tiff_handler): New function, combining the cores of the
16306 old tiff_error_handler and tiff_warning_handler.
16307 This function is rewritten to use vsnprintf and thereby avoid
16308 stack buffer overflows. It uses only the features of vsnprintf
16309 that are common to both POSIX and native Microsoft.
16310 (tiff_error_handler, tiff_warning_handler): Use it.
16311 (tiff_load, gif_load, imagemagick_load_image):
16312 Don't assume :index value fits in 'int'.
16313 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16314 (imagemagick_load_image): Check that crop parameters fit into
16315 the integer types that MagickCropImage accepts. Don't assume
16316 Vimagemagick_render_type has a nonnegative value. Don't assume
16317 size_t fits in 'long'.
16318 (gs_load): Use printmax_t to print the widest integers possible.

16331 handle_single_display_spec, not just 1 or zero.
16332 (handle_single_display_spec): If the display spec is of the form
16333 `(space ...)', and specifies display in the text area, return 2
16335 (try_cursor_movement): Check for the need to scroll more
16336 accurately, and prefer exact match for point under bidi.
16337 Don't advance `row' beyond the last row of the window.

16355 buffers, return left-to-right.
16356 (set_cursor_from_row): Consider candidate row a win if its glyph
16357 represents a newline and point is on that newline. Fixes cursor
16358 positioning on the newline at EOL of R2L text within L2R
16359 paragraph, and vice versa.
16360 (try_cursor_movement): Check continued rows, in addition to
16361 continuation rows. Fixes unwarranted scroll when point enters a
16362 continued line of R2L text within an L2R paragraph, or vice versa.
16363 (cursor_row_p): Consider the case of point being equal to
16364 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16365 from the end of a short line to the beginning of a continued line
16366 of R2L text within L2R paragraph.
16367 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

16390 * xdisp.c (redisplay_window): When computing centering_position,
16391 account for the height of the header line. (Bug#8874)
16393 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16394 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16395 candidate is selected by the mouse, and that candidate has a
16396 composed character under the mouse.
16398 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16399 coordinates reported by pos-visible-in-window-p for a composed
16400 character in column zero.
16402 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

16406 2011-08-22 Eli Zaretskii <eliz@gnu.org>
16408 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16409 consider it a hit if to_charpos is anywhere in the range of the
16410 composed buffer positions.
16412 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16414 * image.c (gif_load): Don't assume that each subimage has the same
16415 dimensions as the base image. Handle disposal method that is
16416 "undefined" by the gif spec (Bug#9335).
16418 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16420 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16425 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16426 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16427 from an Org mode buffer to a Speedbar frame.
16429 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16430 a composition, take its buffer position from IT->cmp_it.charpos.
16431 Fixes cursor positioning at the beginning of a line that begins
16432 with a composed character.
16434 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16436 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16437 character bidirectional type, use STRONG_L instead. Fixes crashes
16438 in a buffer produced by `describe-categories'.
16440 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16441 members before the level stack, so they would be saved and
16442 restored when copying iterator state. Fixes incorrect reordering
16443 around TABs covered by display properties.
16445 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16447 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16457 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16458 has no `load' handler, try opening the file locally. (Bug#9311)
16460 2011-08-16 Ken Brown <kbrown@cornell.edu>
16462 * gmalloc.c: Expand comment.
16464 2011-08-16 Eli Zaretskii <eliz@gnu.org>
16466 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
16467 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
16469 2011-08-16 Ken Brown <kbrown@cornell.edu>
16471 Fix memory allocation problems in Cygwin build (Bug#9273).
16473 * unexcw.c ( __malloc_initialized): Declare external variable.
16474 (fixup_executable): Force the dumped emacs to reinitialize malloc.
16476 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
16478 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
16480 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
16481 in the static heap.
16482 [CYGWIN] (special_realloc): New function.
16483 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
16484 requests to realloc storage in the static heap.
16486 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
16488 * bidi.c (bidi_initialize): Remove unused local.
16490 2011-08-15 Eli Zaretskii <eliz@gnu.org>
16493 * biditype.h: Remove file.

16495 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
16497 * dispextern.h: Fix a typo in the comment to bidi_type_t.
16499 * chartab.c: Improve commentary for the uniprop_table API.
16501 * bidi.c (bidi_paragraph_init): Support zero value of
16502 bidi_ignore_explicit_marks_for_paragraph_level.
16503 (bidi_initialize): Use uniprop_table instead of including
16504 biditype.h and bidimirror.h.
16506 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
16507 coordinates of the iterator when restoring from ppos_it.
16510 2011-08-14 Kenichi Handa <handa@m17n.org>
16512 * process.c (create_process): Call setup_process_coding_systems
16513 after the pid of the process is set to -1 (Bug#8162).
16515 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16517 * xdisp.c (move_it_in_display_line_to): Don't invoke
16518 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16519 ppos_it. Fixes vertical cursor motion when line beginning is
16520 covered by an image. (Bug#9296)
16522 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16524 * nsterm.h (ns_run_ascript): Declare.
16525 (NSAPP_DATA2_RUNASSCRIPT): Define.
16527 * nsfns.m (as_script, as_result, as_status): New static variables.
16528 (ns_run_ascript): New function.
16529 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16530 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16531 the event loop. Get status from as_status (Bug#7276).
16533 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16534 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16535 the event loop (Bug#7276).
16537 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16539 * gnutls.c (QCgnutls_bootprop_priority)
16540 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
16541 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
16542 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
16543 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
16544 (QCgnutls_bootprop_verify_hostname_error)
16545 (QCgnutls_bootprop_callbacks_verify): Rename from
16546 Qgnutls_bootprop_..., all uses changed.
16548 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
16551 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
16553 * xfaces.c (Qframe_set_background_mode): Now static.
16554 * dispextern.h (Qframe_set_background_mode): Remove decl.

16558 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
16560 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16561 (Fnetwork_interface_list): Allocate in increments of bytes instead
16562 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16563 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16565 (struct ifflag_def): notrailers is smart on OSX.
16566 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16567 Get hardware address with getifaddrs if available.
16569 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16571 * xdisp.c (iterate_out_of_display_property): xassert that
16572 IT->position is set to within IT->object's boundaries. Break from
16573 the loop as soon as EOB is reached; avoids infloops in redisplay
16574 when IT->position is set up wrongly due to some bug.
16575 Set IT->current to match the bidi iterator unconditionally.
16576 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16577 entry. Force push_it to save on the stack the current
16578 buffer/string position, to be restored by pop_it. Fix flags in
16579 the iterator structure wrt the object coming from a display
16580 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16581 properties. (Bug#9284)
16583 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16585 * fontset.c (fontset_get_font_group): Add proper type checks.
16588 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16590 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
16591 and LC_VERSION_MIN_MACOSX.
16592 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16593 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16595 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16597 * xdisp.c (forward_to_next_line_start): Allow to use the
16598 no-display-properties-and-no-overlays under bidi display.
16599 Set disp_pos in the bidi iterator to avoid searches for display
16600 properties and overlays.
16602 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16604 * editfns.c (Fset_time_zone_rule): Document relationship with the
16607 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16608 the font entity extracted from the cache (Bug#8109).
16610 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16612 * composite.c (autocmp_chars): Don't reset point. That is done by
16613 restore_point_unwind (Bug#5984).
16615 2011-08-07 Juri Linkov <juri@jurta.org>
16617 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16618 to show the arg `TIME' instead of `TIMEVAL'.
16620 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16622 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16623 display property strides EOL and includes a newline, as in
16624 longlines-mode. (Bug#9254)
16625 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16626 word-wrap under bidirectional display. (Bug#9224)
16628 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16629 is non-zero, even if the data buffer is NULL. Fixes a crash in
16630 vertical-motion with longlines-mode. (Bug#9254)
16632 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16634 * bidi.c <bidi_cache_total_alloc>: Now static.
16635 (bidi_initialize): Initialize bidi_cache_total_alloc.
16637 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16640 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16641 amount allocated this far in `bidi_cache_total_alloc'.
16642 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16643 non-zero, only free the data buffer without restoring the cache
16644 contents. All callers changed.
16646 * dispextern.h (bidi_unshelve_cache): Update prototype.
16648 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16649 (move_it_in_display_line, move_it_to)
16650 (move_it_vertically_backward, move_it_by_lines): Replace the call
16651 to xfree to an equivalent call to bidi_unshelve_cache.
16652 (move_it_in_display_line_to): Fix logic of returning
16653 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16655 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16657 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16658 came from a string character with a `cursor' property. (Bug#9229)
16660 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16662 * Makefile.in (LIB_PTHREAD): New variable.
16663 (LIBES): Add LIB_PTHREAD (Bug#9216).
16665 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16666 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16668 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16670 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16672 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16674 * xterm.c (x_find_topmost_parent): New function.
16675 (x_set_frame_alpha): Find topmost parent window with
16676 x_find_topmost_parent and set the property there also (bug#9181).
16677 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16679 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16681 * callproc.c (Fcall_process): Avoid vfork clobbering
16682 the local vars buffer, coding_systems, current_dir.
16684 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16686 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16688 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16690 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16691 so that it is not optimized away.
16693 * xdisp.c (compute_display_string_pos): Remove unused local.
16695 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16697 Fix slow cursor motion and scrolling in large buffers with
16698 selective display, like Org Mode buffers. (Bug#9218)
16700 * dispextern.h (struct bidi_it): New member disp_prop_p.
16702 * xdisp.c: Remove one-slot cache of display string positions.
16703 (compute_display_string_pos): Accept an additional argument
16704 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16705 for a display string or property. If found, set DISP_PROP_P
16708 * bidi.c (bidi_fetch_char): Accept an additional argument
16709 DISP_PROP_P, and pass it to compute_display_string_pos.
16710 Only handle text covered by a display string if DISP_PROP_P is returned
16711 non-zero. All callers of bidi_fetch_char changed.
16713 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16715 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16717 2010-12-03 Don March <don@ohspite.net>
16719 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16720 last character M-[char] is translated to ESC [char] (bug#7541).
16722 2011-08-02 Kenichi Handa <handa@m17n.org>
16724 * lisp.h (uniprop_table): Extern it.
16726 * chartab.c (uniprop_table): Make it non-static.
16728 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16730 * xdisp.c (forward_to_next_line_start): Accept additional argument
16731 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16733 (reseat_at_next_visible_line_start): Use the bidi iterator state
16734 returned by forward_to_next_line_start to restore the state of
16735 it->bidi_it after backing up to previous newline. (Bug#9212)
16737 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16739 * regex.c (re_comp): Protoize.
16740 (re_exec): Fix return type.
16741 (regexec): Fix type of `ret'. (Bug#9203)
16743 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16745 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16746 This is needed if max-image-size is a floating-point number.
16748 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16750 * print.c (print_object): Print empty symbol as ##.
16752 * lread.c (read1): Read ## as empty symbol.
16754 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16756 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16757 setting frame foreground color (Bug#9175).
16758 (x_set_background_color): Likewise.
16760 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16761 contents (Bug#9176).
16762 (EmacsTooltip -init): Remove bezels and add shadows to
16765 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16766 or scroll bar (Bug#8470).
16768 * nsfont.m (nsfont_open): Remove assignment to voffset and
16769 unnecessary vars hshink, expand, hd, full_height, min_height.
16770 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16772 * nsterm.h (nsfont_info): Remove voffset field.
16774 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16776 Implement strike-through and overline on NextStep (Bug#8863).
16778 * nsfont.m (nsfont_open): Use underline position provided by font,
16779 instead of hard-coded value of 2.
16780 (nsfont_draw): Call ns_draw_text_decoration instead.
16782 * nsterm.h: Add declaration for ns_draw_text_decoration.
16784 * nsterm.m (ns_draw_text_decoration): New function for drawing
16785 underline, overline, and strike-through.
16786 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16787 ns_draw_text_decoration. Change treatment of cursor drawing to
16788 accommodate underlining, etc.
16790 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16792 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16795 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16797 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16798 Without this fix, if a signal arrives just after memory fills up,
16799 'malloc' might be invoked reentrantly.
16801 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16802 In other words, assume that every image size is allowed, on non-X
16803 hosts. This assumption is probably wrong, but it lets Emacs compile.
16805 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16807 * regex.c (re_iswctype): Convert return values to boolean.
16809 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16811 * xdisp.c (compute_display_string_pos): Don't use cached display
16812 string position if the buffer had its restriction changed.
16815 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16817 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16819 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16821 Integer signedness and overflow and related fixes. (Bug#9079)
16823 * bidi.c: Integer size and overflow fixes.
16824 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16825 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16826 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16827 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16828 (bidi_find_other_level_edge):
16829 Use ptrdiff_t instead of EMACS_INT where either will do.
16830 This works better on 32-bit hosts configured --with-wide-int.
16831 (bidi_cache_ensure_space): Check for size-calculation overflow.
16832 Use % rather than repeated addition, for better worst-case speed.
16833 Don't set bidi_cache_size until after xrealloc returns, because it
16835 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16836 (bidi_cache_ensure_space): Also check that the bidi cache size
16837 does not exceed that of the largest Lisp string or buffer. See Eli
16838 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16840 * alloc.c (__malloc_size_t): Remove.
16841 All uses replaced by size_t. See Andreas Schwab's note
16842 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16844 * image.c: Improve checking for integer overflow.
16845 (check_image_size): Assume that f is nonnull, since
16846 it is always nonnull in practice. This is one less thing to
16847 worry about when checking for integer overflow later.
16848 (x_check_image_size): New function, which checks for integer
16849 overflow issues inside X.
16850 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16851 This removes the need for a memory_full check.
16852 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16853 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16854 (xbm_read_bitmap_data): Change locals back to 'int', since
16855 their values must fit in 'int'.
16856 (xpm_load_image, png_load, tiff_load):
16857 Invoke x_create_x_image_and_pixmap earlier,
16858 to avoid much needless work if the image is too large.
16859 (tiff_load): Treat overly large images as if
16860 x_create_x_image_and_pixmap failed, not as malloc failures.
16861 (gs_load): Use x_check_image_size.
16863 * gtkutil.c: Omit integer casts.
16864 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16865 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16867 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16869 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16870 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16871 would wrongly return t on a 64-bit host.
16873 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16874 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16875 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16876 and therefore cause GCC to emit a bogus diagnostic in some cases.
16878 * image.c: Integer signedness and overflow and related fixes.
16879 This is not an exhaustive set of fixes, but it's time to
16880 record what I've got.
16881 (lookup_pixel_color, check_image_size): Remove redundant decls.
16882 (check_image_size): Don't assume that arbitrary EMACS_INT values
16883 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16884 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16885 (tiff_load, imagemagick_load_image):
16886 Check for overflow in size calculations.
16887 (x_create_x_image_and_pixmap): Remove unnecessary test for
16888 xmalloc returning NULL; that can't happen.
16889 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16890 (xpm_color_bucket): Use better integer hashing function.
16891 (xpm_cache_color): Don't possibly over-allocate memory.
16892 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16893 (gif_memory_source):
16894 Use ptrdiff_t, not int or size_t, to record sizes.
16895 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16896 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16897 either works, as we prefer signed integers.
16898 (tiff_read_from_memory, tiff_write_from_memory):
16899 Return tsize_t, not size_t, since that's what the TIFF API wants.
16900 (tiff_read_from_memory): Don't fail simply because the read would
16901 go past EOF; instead, return a short read.
16902 (tiff_load): Omit no-longer-needed casts.
16903 (Fimagemagick_types): Don't assume size fits into 'int'.
16905 Improve hashing quality when configured --with-wide-int.
16906 * fns.c (hash_string): New function, taken from sxhash_string.
16907 Do not discard information about ASCII character case; this
16908 discarding is no longer needed.
16909 (sxhash-string): Use it. Change sig to match it. Caller changed.
16910 * lisp.h: Declare it.
16911 * lread.c (hash_string): Remove, since we now use fns.c's version.
16912 The fns.c version returns a wider integer if --with-wide-int is
16913 specified, so this should help the quality of the hashing a bit.
16915 * emacs.c: Integer overflow minor fix.
16916 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16917 Define only if GNU_LINUX.
16918 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16920 * dispnew.c: Integer signedness and overflow fixes.
16921 Remove unnecessary forward decls, that were a maintenance hassle.
16922 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16924 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16925 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16926 (prepare_desired_row, line_draw_cost):
16927 Use int, not unsigned, where either works.
16928 (save_current_matrix, restore_current_matrix):
16929 Use ptrdiff_t, not size_t, where either works.
16930 (init_display): Check for overflow more accurately, and without
16931 relying on undefined behavior.
16933 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16934 Remove, replacing with the new symbols in lisp.h. All uses changed.
16935 * fileio.c (make_temp_name):
16936 * filelock.c (lock_file_1, lock_file):
16937 * xdisp.c (message_dolog):
16938 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16939 Use pMd etc. instead.
16940 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16941 replacing the pWIDE etc. symbols removed from editfns.c.
16943 * keyboard.h (num_input_events): Now uintmax_t.
16944 This is (very slightly) less likely to mess up due to wraparound.
16947 * buffer.c: Integer signedness fixes.
16948 (alloc_buffer_text, enlarge_buffer_text):
16949 Use ptrdiff_t rather than size_t when either will do, as we prefer
16952 * alloc.c: Integer signedness and overflow fixes.
16953 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16954 (__malloc_size_t): Default to size_t, not to int.
16955 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16956 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16957 Prefer ptrdiff_t to size_t when either would do, as we prefer
16959 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16960 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16961 Now const. Initialize with values that are in range even if char
16963 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16964 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16965 These functions do the right thing with sizes > 2**32.
16966 (check_depth): Now ptrdiff_t, not int.
16967 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16968 Adjust to new way of storing sizes. Check for size overflow bugs
16970 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16971 slightly wrong anyway, as it missed one instance of
16972 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16973 (refill_memory_reserve): Omit needless cast to size_t.
16974 (mark_object_loop_halt): Mark as externally visible.
16976 * xselect.c: Integer signedness and overflow fixes.
16977 (Fx_register_dnd_atom, x_handle_dnd_message):
16978 Use ptrdiff_t, not size_t, since we prefer signed.
16979 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16980 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16981 x_dnd_atoms_size and x_dnd_atoms_length.
16983 * doprnt.c: Prefer signed to unsigned when either works.
16985 * doprnt.c (doprnt):
16987 * xdisp.c (vmessage):
16988 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16989 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16990 prefer signed arithmetic to avoid comparison confusion.
16991 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16992 but is a bit tricky.
16994 Assume freestanding C89 headers, string.h, stdlib.h.
16995 * data.c, doprnt.c, floatfns.c, print.c:
16996 Include float.h unconditionally.
16997 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16998 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16999 * regex.c: Likewise for stddef.h, string.h.
17000 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17001 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17002 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17003 (STDC_HEADERS): Remove obsolete defines.
17004 * sysdep.c: Include limits.h unconditionally.
17006 Assume support for memcmp, memcpy, memmove, memset.
17007 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17008 * regex.c (memcmp, memcpy):
17009 Remove; we assume C89 now.
17011 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17012 (__malloc_safe_bcopy): Remove; no longer needed.
17014 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17015 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17016 well either way, and we prefer signed to unsigned.
17018 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17020 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17021 closes the connection while we're reading (bug#9182).
17023 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17025 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17026 are specified (Bug#9168).
17028 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17030 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17031 Found by GCC static checking and --with-wide-int on a 32-bit host.
17033 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17035 * xdisp.c (compute_display_string_pos): Fix logic of caching
17036 previous display string position. Initialize cached_prev_pos to
17037 -1. Fixes slow-down at the beginning of a buffer.
17039 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17041 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17042 for attrs[LFACE_FONTSET_INDEX].
17044 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17046 * xml.c (parse_region): Remove unused local
17047 that was recently introduced.
17049 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17051 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17052 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17054 * xdisp.c (move_it_in_display_line_to): Record the best matching
17055 position for TO_CHARPOS while scanning the line, and restore it on
17056 exit if none of the characters scanned was an exact match.
17057 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17058 when exact match is impossible due to invisible text, and the
17059 lines are truncated.
17061 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17063 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17066 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17068 Fix a significant slow-down of cursor motion with C-n, C-p,
17069 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17070 auto-repeat under bidi redisplay in fontified buffers.
17071 * xdisp.c (compute_stop_pos_backwards): New function.
17072 (next_element_from_buffer): Call compute_stop_pos_backwards to
17073 find a suitable prev_stop when we find ourselves before
17075 (reseat): Don't look for prev_stop, as that could mean a very long
17077 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17078 <cached_disp_overlay_modiff>: Cache for last found display string
17080 (compute_display_string_pos): Return the cached position if asked
17081 about the same buffer in the same area of character positions, and
17082 the buffer wasn't changed since the time the display string
17083 position was cached.
17085 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17087 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17088 is an integer, which is important for empty lines. (Bug#9149)
17090 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17092 * frame.c (Fmodify_frame_parameters): In tty case, update the
17093 default face if necessary (Bug#4238).
17095 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17097 * editfns.c (Fstring_to_char): No need to explain what a character
17098 is in the docstring (Bug#6576).
17100 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17102 * xml.c (parse_region): Make sure we always return a tree.
17104 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17106 * xml.c (parse_region): If a document contains only comments,
17109 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17111 * xml.c (make_dom): Return comments, too.
17113 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17116 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17117 and the surrounding thread.
17118 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17119 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17120 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17122 * s/openbsd.h (BROKEN_SIGIO): Define.
17123 * unexelf.c (unexec) [__OpenBSD__]:
17124 Don't update the .mdebug section of the Alpha COFF symbol table.
17126 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17128 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17131 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17133 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17134 This fixes some race conditions on the permissions of any newly
17137 * alloc.c (valid_pointer_p): Use pipe, not open.
17138 This fixes some permissions issues when debugging.
17140 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17141 If fchown fails to set both uid and gid, try to set just gid,
17142 as that is sometimes allowed. Adjust the file's mode to eliminate
17143 setuid or setgid bits that are inappropriate if fchown fails.
17145 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17147 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17148 to compare Lisp_Objects.
17149 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17150 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17151 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17153 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17155 * lread.c (read_integer): Unread even EOF character.
17156 (read1): Likewise. Properly record start position of symbol.
17158 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17159 symbol character follows.
17161 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17163 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17164 This works around a problem with the previous change to Fcopy_file.
17165 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17166 and without this change, GCC might complain about discarding
17167 fchown's return value.
17169 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17171 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17173 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17175 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17177 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17179 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17180 it's used from the C level.
17182 * process.c: Use the same condition for POLL_FOR_INPUT in both
17183 keyboard.c and process.c (bug#1858).
17185 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17187 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17188 (Fgnutls_boot): Use it.
17190 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17192 * doc.c (Fsubstitute_command_keys): Revert last change.
17194 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17196 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17197 quotes the next character, and doesn't affect other longer
17198 sequences (bug#8935).
17200 * lread.c (syms_of_lread): Clarify that is isn't only
17201 `eval-buffer' and `eval-defun' that's affected by
17202 `lexical-binding' (bug#8460).
17204 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17206 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17207 bidi redisplay when a line includes both an image and is truncated.
17209 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17211 Fix minor problems found by static checking.
17212 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17213 (elsz): Now a signed constant, not a size_t var. We prefer signed
17214 types to unsigned, to avoid integer comparison confusion. Without
17215 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17216 "cannot optimize loop, the loop counter may overflow", a symptom
17218 * indent.c (Fvertical_motion): Mark locals as initialized.
17219 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17221 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17223 * search.c (Fre_search_backward): Mention `case-fold-search' in
17224 all the re_search_* functions (bug#8138).
17226 * keyboard.c (Fopen_dribble_file): Document when the file is
17229 2011-07-14 Eli Zaretskii <eliz@gnu.org>
17231 * bidi.c (bidi_dump_cached_states): Fix format of displaying
17234 Support bidi reordering of display and overlay strings.

17237 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
17238 (reseat_to_string): Initialize bidi_it->string.s and
17239 bidi_it->string.schars.
17240 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
17241 NULL (avoids a crash in bidi_paragraph_init).
17242 Initialize itb.string.lstring.
17243 (init_iterator): Call bidi_init_it only of a valid
17244 buffer position was specified. Initialize paragraph_embedding to
17246 (reseat_to_string): Initialize the bidi iterator.
17247 (display_string): If we need to ignore text properties of
17248 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17249 original value of -1 will not work with bidi.)
17250 (compute_display_string_pos): First arg is now struct
17251 `text_pos *'; all callers changed. Support display properties on
17253 (compute_display_string_end): Support display properties on Lisp
17255 (init_iterator, reseat_1, reseat_to_string): Initialize the
17256 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17257 when iterating on a string not from display properties).
17258 (compute_display_string_pos, compute_display_string_end):
17259 Fix calculation of the object to scan. Fixes an error when using
17261 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17262 base_level_stop; instead, set base_level_stop to BEGV.
17263 Fixes crashes in vertical-motion.
17264 (next_element_from_buffer): Improve commentary for when
17265 the iterator is before prev_stop.
17266 (init_iterator): Initialize bidi_p from the default value of
17267 bidi-display-reordering, not from buffer-local value. Use the
17268 buffer-local value only if initializing for buffer iteration.
17269 (handle_invisible_prop): Support invisible properties on strings
17270 that are being bidi-reordered.
17271 (set_iterator_to_next): Support bidi reordering of C strings and
17273 (next_element_from_string): Support bidi reordering of Lisp
17275 (handle_stop_backwards): Support Lisp strings as well.
17276 (display_string): Support display of R2L glyph rows.
17277 Use IT_STRING_CHARPOS when displaying from a Lisp string.
17278 (init_iterator): Don't initialize it->bidi_p for strings
17280 (reseat_to_string): Initialize it->bidi_p for strings here.
17281 (next_element_from_string, next_element_from_c_string)
17282 (next_element_from_buffer): Add xassert's for correspondence
17283 between IT's object being iterated and it->bidi_it.string
17285 (face_before_or_after_it_pos): Support bidi iteration.
17286 (next_element_from_c_string): Handle the case of the first string
17287 character that is not the first one in the visual order.
17288 (get_visually_first_element): New function, refactored from common
17289 parts of next_element_from_buffer, next_element_from_string, and
17290 next_element_from_c_string.
17291 (tool_bar_lines_needed, redisplay_tool_bar)
17292 (display_menu_bar): Force left-to-right direction. Add a FIXME
17293 comment for making that be controlled by a user option.
17294 (push_it, pop_it): Save and restore the state of the
17295 bidi iterator. Save and restore the bidi_p flag.
17296 (pop_it): Iterate out of display property for string iteration as
17298 (iterate_out_of_display_property): Support iteration over strings.
17299 (handle_single_display_spec): Set up it->bidi_it for iteration
17300 over a display string, and call bidi_init_it.
17301 (handle_single_display_spec, next_overlay_string)
17302 (get_overlay_strings_1, push_display_prop): Set up the bidi
17303 iterator for displaying display or overlay strings.
17304 (forward_to_next_line_start): Don't use the shortcut if
17306 (back_to_previous_visible_line_start): If handle_display_prop
17307 pushed the iterator stack, restore the internal state of the bidi
17308 iterator by calling bidi_pop_it same number of times.
17309 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17310 and we are bidi-iterating, don't decrement the iterator position;
17311 instead, set the first_elt flag in the bidi iterator, to produce
17313 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17314 (push_display_prop): xassert that we are iterating a buffer.
17315 (push_it, pop_it): Save and restore paragraph_embedding member.
17316 (handle_single_display_spec, next_overlay_string)
17317 (get_overlay_strings_1, reseat_1, reseat_to_string)
17318 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17319 correctly. Don't assume unibyte strings are not bidi-reordered.
17320 (compute_display_string_pos)
17321 (compute_display_string_end): Fix handling the case of C string.
17322 (push_it, pop_it): Save and restore from_disp_prop_p.
17323 (handle_single_display_spec, push_display_prop): Set the
17324 from_disp_prop_p flag.
17325 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
17326 (pop_it): Call iterate_out_of_display_property only if we are
17327 popping after iteration over a string that came from a display
17328 property. Fix a typo in popping stretch info. Add an assertion
17329 for verifying that the iterator position is in sync with the bidi
17331 (handle_single_display_spec, get_overlay_strings_1)
17332 (push_display_prop): Fix initialization of paragraph direction for
17333 string when that of the parent object is not yet determined.
17334 (reseat_1): Call bidi_init_it to resync the bidi
17335 iterator with IT's position. (Bug#7616)
17336 (find_row_edges): If ROW->start.pos gives position
17337 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
17338 (handle_stop, back_to_previous_visible_line_start, reseat_1):
17339 Reset the from_disp_prop_p flag.
17340 (SAVE_IT, RESTORE_IT): New macros.
17341 (pos_visible_p, face_before_or_after_it_pos)
17342 (back_to_previous_visible_line_start)
17343 (move_it_in_display_line_to, move_it_in_display_line)
17344 (move_it_to, move_it_vertically_backward, move_it_by_lines)
17345 (try_scrolling, redisplay_window, display_line): Use them when
17346 saving a temporary copy of the iterator and restoring it back.
17347 (back_to_previous_visible_line_start, reseat_1)
17348 (init_iterator): Empty the bidi cache "stack".

17787 Prefer signed to unsigned, since the signedness doesn't matter and
17788 in general we prefer signed. When given a limit, use a
17789 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17790 latter isn't right if USE_2_TAGS_FOR_INTS.
17791 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17792 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17796 * textprop.c (text_property_stickiness):
17797 Obey Vtext_property_default_nonsticky.
17798 (syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.

17805 This is more efficient than Ffile_directory_p and avoids a minor race.
17807 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17809 * buffer.c (Foverlay_put): Say what the return value is
17812 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17813 is a directory before asking whether to use the file name
17815 (barf_or_query_if_file_exists): Make the "File is a directory"
17816 error be more correct.
17818 * fns.c (Frequire): Remove the mention of the .gz files, since
17819 that's installation-specific, but keep the mention of
17820 `get-load-suffixes'.
17822 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
17824 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

17829 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
17830 (syms_of_gnutls): Remove duplicate DEFSYM for
17831 Qgnutls_bootprop_verify_hostname_error, an error for
17832 Qgnutls_bootprop_verify_error (which is no longer used).
17834 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17835 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17836 Also (re)move comments that are misplaced or no longer relevant.

17937 * eval.c (struct backtrace): Simplify and port the data structure.
17938 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17939 signed bit field, as this assumption is not portable and it makes
17940 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17941 "char debug_on_exit : 1" as this is not portable either; instead,
17942 use the portable "unsigned int debug_on_exit : 1". Remove unused
17943 member evalargs. Remove obsolete comments about cc bombing out.
17945 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
17947 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

18015 (emacs_fixed_get_preferred_height): Use min_width/height from
18016 frames size_hint to set minimum and natural (Bug#8919).
18017 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
18018 and use min_width/height from frames size_hint to set
18019 min_width/height (Bug#8919).

18112 (PRINTPREPARE, printchar, strout):
18113 Don't set size unless allocation succeeds.
18115 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18116 for sizes. Check for string overflow more accurately.

18131 to improve quality of diagnostics for out-of-range radices.
18132 Calculate buffer size correctly for out-of-range radices.
18133 (read1): Check for integer overflow in radices, and in
18134 read-circle numbers.
18135 (read_escape): Avoid int overflow.
18136 (Fload, openp, read_buffer_size, read1)
18137 (substitute_object_recurse, read_vector, read_list, map_obarray):

18160 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18161 The following patches are for when GLYPH_DEBUG && !XASSERT.
18162 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18163 * dispnew.c (flush_stdout):
18164 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18165 Mark as externally visible.
18166 * dispnew.c (check_window_matrix_pointers): Now static.
18167 * dispnew.c (window_to_frame_vpos):
18168 * xfns.c (unwind_create_frame):

18177 (debug_method_add): Use va_list and vsprintf rather than relying
18178 on undefined behavior with wrong number of arguments.
18179 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18180 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18181 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18182 since we're not interested in debugging glyphs with old libraries.
18183 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18184 GCC 4.6.0's static checking.
18186 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

18220 Use ptrdiff_t, not int, for sizes.
18221 (overlays_at, overlays_in): Check for size-calculation overflow.
18223 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18225 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18226 (x_session_initialize): Do not assume string length fits in int.
18228 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18229 This is unlikely, but can occur if DPI is outlandish.
18231 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18232 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18234 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18235 * xrdb.c (magic_file_p, search_magic_path):
18236 Omit last arg SUFFIX; it was always 0. All callers changed.
18237 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18239 * xfont.c (xfont_match): Avoid need for strlen.
18241 * xfns.c: Don't assume strlen fits in int.
18242 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18244 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18245 not unsigned long, as we prefer signed integers. All callers changed.
18246 Detect integer overflow in repeat count.
18247 (message_dolog): Don't assume print length fits in 39 bytes.
18248 (display_mode_element): Don't assume strlen fits in int.
18250 * termcap.c: Don't assume sizes fit in int and never overflow.
18251 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18252 (gobble_line): Check for size-calculation overflow.
18254 * minibuf.c (Fread_buffer):
18255 * lread.c (intern, intern_c_string):
18256 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18257 Don't assume string length fits in int.
18259 * keyboard.c (parse_tool_bar_item):
18260 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18262 * font.c: Don't assume string length fits in int.
18263 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18264 Use ptrdiff_t, not int.
18265 (font_intern_prop): Don't assume string length fits in int.
18266 Don't assume integer property fits in fixnum.
18267 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18269 * filelock.c: Fix some buffer overrun and integer overflow issues.
18270 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18271 Reformulate so as not to need the command string.
18272 Invoke gzip -cd rather than gunzip, as it's more portable.
18273 (lock_info_type, lock_file_1, lock_file):
18274 Don't assume pid_t and time_t fit in unsigned long.
18275 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18276 (current_lock_owner): Prefer signed type for sizes.
18277 Use memcpy, not strncpy, where memcpy is what is really wanted.
18278 Don't assume (via atoi) that time_t and pid_t fit in int.
18279 Check for time_t and/or pid_t out of range, e.g., via a network share.
18280 Don't alloca where an auto var works fine.
18282 * fileio.c: Fix some integer overflow issues.
18283 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18284 Don't assume string length fits in int.
18285 (directory_file_name): Don't assume string length fits in long.
18286 (make_temp_name): Don't assume pid fits in int, or that its print
18287 length is less than 20.
18289 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18291 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18293 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18295 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18296 We prefer signed integers, even for size calculations.
18298 * emacs.c: Don't assume string length fits in 'int'.
18299 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18300 (main): Don't invoke strlen when not needed.
18302 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18303 (XD_DEBUG_MESSAGE): Don't waste a byte.
18305 * callproc.c (getenv_internal_1, getenv_internal)
18306 (Fgetenv_internal):
18307 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18309 * lread.c (invalid_syntax): Omit length argument.
18310 All uses changed. This doesn't fix a bug, but it simplifies the
18311 code away from its former Hollerith-constant appearance, and it's
18312 one less 'int' to worry about when looking at integer-overflow issues.
18313 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18315 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18316 This didn't break anything, but it didn't help either.
18317 It's confusing to put a bogus integer in a place where the actual
18318 value does not matter.
18319 (LIST_END_P): Remove unused macro and its bogus comment.
18320 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18322 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18323 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18325 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18326 We prefer signed types, and the value cannot exceed the EMACS_INT
18327 range anyway (because otherwise the length would not be representable).
18328 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18329 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18330 This avoids a GCC warning when WIDE_EMACS_INT.
18332 * indent.c (sane_tab_width): New function.
18333 (current_column, scan_for_column, Findent_to, position_indentation)
18334 (compute_motion): Use it. This is just for clarity.
18335 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18337 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18339 * lisp.h (lint_assume): New macro.
18340 * composite.c (composition_gstring_put_cache):
18341 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18343 * editfns.c, insdel.c:
18344 Omit unnecessary forward decls, to simplify future changes.
18346 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18348 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18350 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18351 Use much-faster test for byte-length change.
18352 Don't assume string byte-length fits in 'int'.
18353 Check that character arg fits in 'int'.
18354 (mapcar1): Declare byte as byte, for clarity.
18356 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18358 * fns.c (concat): Catch string overflow earlier.
18359 Do not rely on integer wraparound.
18361 * dispextern.h (struct it.overlay_strings_charpos)
18362 (struct it.selective): Now EMACS_INT, not int.
18363 * xdisp.c (forward_to_next_line_start)
18364 (back_to_previous_visible_line_start)
18365 (reseat_at_next_visible_line_start, next_element_from_buffer):
18366 Don't arbitrarily truncate the value of 'selective' to int.
18368 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18370 * composite.c: Don't truncate sizes to 'int'.
18371 (composition_gstring_p, composition_reseat_it)
18372 (composition_adjust_point): Use EMACS_INT, not int.
18373 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18374 not EMACS_UINT, for indexes.
18376 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18378 * buffer.c: Include <verify.h>.
18379 (struct sortvec.priority, struct sortstr.priority):
18380 Now EMACS_INT, not int.
18381 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18382 (struct sortstr.size, record_overlay_string)
18383 (struct sortstrlist.size, struct sortlist.used):
18384 Don't truncate size to int.
18385 (record_overlay_string): Check for size-calculation overflow.
18386 (init_buffer_once): Check at compile-time, not run-time.
18388 2011-06-22 Jim Meyering <meyering@redhat.com>
18390 Don't leak an XBM-image-sized buffer
18391 * image.c (xbm_load): Free the image buffer after using it.
18393 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18396 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18397 that Sun C diagnosed.
18398 * fns.c (secure_hash): Fix pointer signedness issue.
18399 * intervals.c (static_offset_intervals): New function.
18400 (offset_intervals): Use it.
18402 2011-06-21 Leo Liu <sdl.web@gmail.com>
18405 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18408 * fns.c (secure_hash): Rename from crypto_hash_function and change
18409 the first arg to accept symbols.
18410 (Fsecure_hash): New primitive.
18411 (syms_of_fns): New symbols.
18413 2011-06-20 Deniz Dogan <deniz@dogan.se>
18415 * process.c (Fset_process_buffer): Clarify return value in
18418 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18420 * dispnew.c (add_window_display_history): Use BVAR.
18422 * xdisp.c (debug_method_add): Use BVAR.
18423 (check_window_end, dump_glyph_matrix, dump_glyph)
18424 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18426 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18429 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18430 check till after the cache is created in init_frame_faces.
18432 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18434 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18436 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18438 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18439 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18440 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18442 Improve buffer-overflow checking (Bug#8873).
18443 * fileio.c (Finsert_file_contents):
18444 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18445 Remove the old (too-loose) buffer overflow checks.
18446 They weren't needed, since make_gap checks for buffer overflow.
18447 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18448 The old code merely checked for Emacs fixnum overflow, and relied
18449 on undefined (wraparound) behavior. The new code avoids undefined
18450 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18452 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18453 Tune. Don't use wider integers than needed. Don't use alloca.
18454 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18456 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18458 * insdel.c, lisp.h (buffer_overflow): New function.
18459 (insert_from_buffer_1, replace_range, replace_range_2):
18460 * insdel.c (make_gap_larger):
18461 * editfns.c (Finsert_char):
18462 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18464 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18466 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18468 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18470 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18471 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18473 * fileio.c: Don't assume EMACS_INT fits in off_t.
18474 (emacs_lseek): New static function.
18475 (Finsert_file_contents, Fwrite_region): Use it.
18476 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18478 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18480 * fns.c: Don't overflow int when computing a list length.
18481 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18482 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18483 truncation on 64-bit hosts. Check for QUIT every
18484 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18485 faster and is responsive enough.
18486 (Flength): Report an error instead of overflowing an integer.
18487 (Fsafe_length): Return a float if the value is not representable
18488 as a fixnum. This shouldn't happen except in contrived situations.
18489 (Fnthcdr, Fsort): Don't assume list length fits in int.
18490 (Fcopy_sequence): Don't assume vector length fits in int.
18492 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18493 (header_size, word_size): New constants.
18494 (allocate_vectorlike): Don't check size overflow here.
18495 (allocate_vector): Check it here instead, since this is the only
18496 caller of allocate_vectorlike that could cause overflow.
18497 Check that the new vector's length is representable as a fixnum.
18499 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18500 The previous code was bogus. For example, next_almost_prime (32)
18501 returned 39, which is undesirable as it is a multiple of 3; and
18502 next_almost_prime (24) returned 25, which is a multiple of 5 so
18503 why was the code bothering to check for multiples of 7?
18505 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18507 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18509 Variadic C functions now count arguments with ptrdiff_t.
18510 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18511 Back then I didn't know that the Emacs coding style prefers signed int.
18512 Also, in the meantime I found a few more instances where arguments
18513 were being counted with int, which may truncate counts on 64-bit
18514 machines, or EMACS_INT, which may be unnecessarily wide.
18515 * lisp.h (struct Lisp_Subr.function.aMANY)
18516 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18517 Arg counts are now ptrdiff_t, not size_t.
18518 All variadic functions and their callers changed accordingly.
18519 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18520 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18521 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18522 * callint.c (Fcall_interactively): Check arg count for overflow,
18523 to avoid potential buffer overrun. Use signed char, not 'int',
18524 for 'varies' array, so that we needn't bother to check its size
18525 calculation for overflow.
18526 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18527 * eval.c (apply_lambda):
18528 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18529 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18530 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18532 * callint.c (Fcall_interactively): Don't use index var as event count.
18534 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18535 * mem-limits.h (SIZE): Remove; no longer used.
18537 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18539 Remove unnecessary casts.
18540 * xterm.c (x_term_init):
18541 * xfns.c (x_set_border_pixel):
18542 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18543 These aren't needed now that we assume ANSI C.
18545 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18546 It's more likely to cause problems (due to unsigned overflow)
18549 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18551 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18553 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18555 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18557 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18559 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18561 GLYPH_CODE_FACE returns EMACS_INT, not int.
18562 * dispextern.h (merge_faces):
18563 * xfaces.c (merge_faces):
18564 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18565 Don't assume EMACS_INT fits in int.
18567 * character.h (CHAR_VALID_P): Remove unused parameter.
18568 * fontset.c, lisp.h, xdisp.c: All uses changed.
18570 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18572 * fns.c (concat): Minor tuning based on overflow analysis.
18573 This doesn't fix any bugs. Use int to hold character, instead
18574 of constantly refetching from Emacs object. Use XFASTINT, not
18575 XINT, for value known to be a character. Don't bother comparing
18576 a single byte to 0400, as it's always less.
18578 * floatfns.c (Fexpt):
18579 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18581 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18584 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18586 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18587 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18588 incorrectly succeed when S was a string, because 4294967386 was
18589 truncated before it was used.
18591 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18592 Otherwise, an out-of-range integer could cause undefined behavior
18595 * composite.c: Use int, not EMACS_INT, for characters.
18596 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18597 EMACS_INT, for values that are known to be in character range.
18598 This doesn't fix any bugs but is the usual style inside Emacs and
18599 may generate better code on 32-bit machines.
18601 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18602 This is for reasons similar to the recent CHAR_STRING fix.
18603 * charset.c (Fencode_char): Check that character arg is actually
18604 a character. Pass an int to ENCODE_CHAR.
18605 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18606 wider than 'int', as a compile-time check to prevent future regressions
18609 * character.c (char_string): Remove unnecessary casts.
18611 Make sure a 64-bit char is never passed to CHAR_STRING.
18612 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18613 by silently ignoring the top 32 bits, allowing some values
18614 that were far too large to be valid characters.
18615 * character.h: Include <verify.h>.
18616 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18617 arguments are no wider than unsigned, as a compile-time check
18618 to prevent future regressions in this area.
18620 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18621 (Fsubst_char_in_region):
18623 * xdisp.c (decode_mode_spec_coding):
18624 Adjust to CHAR_STRING's new requirement.
18625 * editfns.c (Finsert_char, Fsubst_char_in_region):
18626 * fns.c (concat): Check that character args are actually
18627 characters. Without this test, these functions did the wrong
18628 thing with wildly out-of-range values on 64-bit hosts.
18630 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18631 These casts should not be needed on 32-bit hosts, either.
18632 * keyboard.c (read_char):
18633 * lread.c (Fload): Remove casts to unsigned.
18635 * lisp.h (UNSIGNED_CMP): New macro.
18636 This fixes comparison bugs on 64-bit hosts.
18637 (ASCII_CHAR_P): Use it.
18638 * casefiddle.c (casify_object):
18639 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18640 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18641 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18642 * dispextern.h (FACE_FROM_ID):
18643 * keyboard.c (read_char): Use UNSIGNED_CMP.
18645 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18646 not to EMACS_INT, to avoid GCC warning.
18648 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18650 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18651 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18652 isn't needed on 32-bit machines.
18654 * buffer.c (Fgenerate_new_buffer_name):
18655 Use EMACS_INT for count, not int.
18656 (advance_to_char_boundary): Return EMACS_INT, not int.
18658 * data.c (Qcompiled_function): Now static.
18660 * window.c (window_body_lines): Now static.
18662 * image.c (gif_load): Rename local to avoid shadowing.
18664 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18665 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18666 * alloc.c (make_save_value): Integer argument is now of type
18667 ptrdiff_t, not int.
18668 (mark_object): Use ptrdiff_t, not int.
18669 * lisp.h (pD): New macro.
18670 * print.c (print_object): Use it.
18672 * alloc.c: Use EMACS_INT, not int, to count objects.

18683 These were 'int' variables that could overflow on 64-bit hosts;
18684 they were never used, so remove them instead of repairing them.

18702 (allocate_string_data): Check for string overflow. This catches
18703 some instances we weren't catching before. Also, it catches
18704 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18705 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18706 and ptrdiff_t and EMACS_INT are both 64 bits.
18708 * character.c, coding.c, doprnt.c, editfns.c, eval.c:

19214 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
19215 Do not assume that spare memory exists; that assumption is valid
19216 only if SYSTEM_MALLOC.
19217 (LARGE_REQUEST): New macro, so that the issue of large requests

19287 instead of using explicit *_CHAR codes.
19288 (bidi_resolve_explicit, bidi_resolve_weak):

19297 (bidi_level_of_next_char): Don't try to lookup the cache for the
19298 next/previous character if nothing is cached there yet, or if we
19299 were just reseat()'ed to a new position.
19301 * xdisp.c (set_cursor_from_row): Set start and stop points
19302 according to the row's direction when priming the loop that looks

19305 (display_prop_intangible_p): Reimplement to call
19306 handle_display_spec instead of single_display_spec_intangible_p.
19307 Accept 3 additional arguments needed by handle_display_spec.
19308 This fixes incorrect cursor motion across display property with complex

19311 lists with the argument STRING its top-level element.
19312 (display_prop_string_p): Fix the condition for processing a

19316 (compute_display_string_pos): Accept additional argument
19317 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19318 value of a `display' property is a "replacing spec".
19319 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19320 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19321 the display property, but just return a value indicating whether
19322 the display property will replace the characters it covers.
19323 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19324 frame_window_p members of struct bidi_it.
19325 (compute_display_string_pos, compute_display_string_end):

19348 All callers changed. (Bug#8762)
19350 * gnutls.c: Use Emacs's memory allocators.
19351 Without this change, the gnutls library would invoke malloc etc.
19352 directly, which causes problems on non-SYNC_INPUT hosts, and which
19353 runs afoul of improving memory_full behavior. (Bug#8761)
19354 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19355 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19356 xfree instead of the default malloc, realloc, free.
19357 (Fgnutls_boot): No need to check for memory allocation failure,
19358 since xmalloc does that for us.
19360 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

19380 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19381 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19382 * alloc.c (allocate_vectorlike):
19383 Check for overflow in vector size calculations.
19384 * ccl.c (ccl_driver):
19385 Check for overflow when converting EMACS_INT to int.

19387 need to be updated by these changes.
19388 * fns.c (make_hash_table, maybe_resize_hash_table):
19389 Check for integer overflow with large hash tables.
19390 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19391 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19392 (SXHASH_REDUCE): New macro.
19393 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19394 Use it instead of discarding useful hash info with large hash values.
19395 (sxhash_float): New function.
19396 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19397 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19398 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19399 Rewrite to use FIXNUM_BITS, as this simplifies things.
19400 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19401 Adjust signatures to match updated version of code.
19402 (consing_since_gc): Now EMACS_INT, since a single hash table can
19403 use more than INT_MAX bytes.

19452 Make it possible to run ./temacs.
19454 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19455 syms_of_callproc does the same thing. Remove test for

19516 * fns.c (to_uchar): Define.
19517 (crypto_hash_function): Use it to convert some newly-signed
19518 variables to unsigned, to avoid sign-extension bugs. For example,
19519 without this change, (md5 "truc") would evaluate to
19520 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19521 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in

19537 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19538 Use XFASTINT rather than XUINT when numbers are nonnegative.
19539 (xd_append_arg, Fdbus_method_return_internal):
19540 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19541 arguments, check that Lisp number is nonnegative, rather than
19542 silently wrapping negative numbers around. (Bug#8722)
19543 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19546 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19548 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19550 ccl: Add integer overflow checks.
19551 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19552 (IN_INT_RANGE): New macros.
19553 (ccl_driver): Use them to check for integer overflow when
19554 decoding a CCL program. Many of the new checks are whether XINT (x)
19555 fits in int; it doesn't always, on 64-bit hosts. The new version
19556 doesn't catch all possible integer overflows, but it's an
19557 improvement. (Bug#8719)
19559 * alloc.c (make_event_array): Use XINT, not XUINT.
19560 There's no need for unsigned here.
19562 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19563 This follows up to the 2011-05-06 change that substituted uintptr_t
19564 for EMACS_INT. This case wasn't caught back then.
19566 Rework Fformat to avoid integer overflow issues.
19567 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19568 now (part of C89). Include <verify.h>.
19569 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19570 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19571 (Fformat): Avoid the prepass trying to compute sizes; it was only
19572 approximate and thus did not catch overflow reliably. Instead, walk
19573 through the format just once, formatting and computing sizes as we go,
19574 checking for integer overflow at every step, and allocating a larger
19575 buffer as needed. Keep track separately whether the format is
19576 multibyte. Keep only the most-recently calculated precision, rather
19577 than them all. Record whether each argument has been converted to
19578 string. Use EMACS_INT, not int, for byte and char and arg counts.
19579 Support field widths and precisions larger than INT_MAX. Avoid
19580 sprintf's undefined behavior with conversion specifications such as %#d
19581 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19582 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19583 formatting out-of-range floating point numbers with int
19584 formats. (Bug#8668)
19586 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19588 * data.c: Avoid integer truncation in expressions involving floats.
19589 * data.c: Include <intprops.h>.
19590 (arith_driver): When there's an integer overflow in an expression
19591 involving floating point, convert the integers to floating point
19592 so that the resulting value does not suffer from catastrophic
19593 integer truncation. For example, on a 64-bit host (* 4
19594 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19595 Do not rely on undefined behavior after integer overflow.
19597 merge count_size_as_multibyte, parse_str_to_multibyte
19598 * character.c, character.h (count_size_as_multibyte):
19599 Rename from parse_str_to_multibyte; all uses changed.
19600 Check for integer overflow.
19601 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19602 since it's now a duplicate of the other. This is more of
19603 a character than a buffer op, so better that it's in character.c.
19604 * fns.c, print.c: Adjust to above changes.
19606 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19608 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19610 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19612 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19613 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19614 (x_clipboard_manager_save): Now static.
19615 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19617 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19618 (crypto_hash_function): Now static.
19619 Fix pointer signedness problems. Avoid unnecessary initializations.
19621 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19623 * termhooks.h (Vselection_alist): Make it terminal-local.
19625 * terminal.c (create_terminal): Initialize it.
19627 * xselect.c: Support for clipboard managers.
19628 (Vselection_alist): Move to termhooks.h as terminal-local var.
19629 (LOCAL_SELECTION): New macro.
19630 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19631 (symbol_to_x_atom): Remove gratuitous arg.
19632 (x_handle_selection_request, lisp_data_to_selection_data)
19633 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19634 (x_own_selection, x_get_local_selection, x_convert_selection):
19635 New arg, specifying work frame. Use terminal-local Vselection_alist.
19636 (some_frame_on_display): Delete unused function.
19637 (Fx_own_selection_internal, Fx_get_selection_internal)
19638 (Fx_disown_selection_internal, Fx_selection_owner_p)
19639 (Fx_selection_exists_p): New optional frame arg.
19640 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19641 (x_handle_selection_clear): Don't treat other terminals with the
19642 same keyboard specially. Use the terminal-local Vselection_alist.
19643 (x_clear_frame_selections): Use Frun_hook_with_args.
19645 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19647 * xterm.h: Add support for those atoms.
19649 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19651 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19652 (converted_selections, conversion_fail_tag): New global variables.
19653 (x_selection_request_lisp_error): Free the above.
19654 (x_get_local_selection): Remove unnecessary code.
19655 (x_reply_selection_request): Args changed; handle arbitrary array
19656 of converted selections stored in converted_selections.
19657 Separate the XChangeProperty and SelectionNotify steps.
19658 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19659 (x_convert_selection): New function.
19660 (x_handle_selection_event): Simplify.
19661 (x_get_foreign_selection): Don't ignore incoming requests while
19662 waiting for an answer; this will fail when we implement
19663 SAVE_TARGETS, and seems unnecessary anyway.
19664 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19665 (Vx_sent_selection_functions): Doc fix.
19667 2011-05-26 Leo Liu <sdl.web@gmail.com>
19669 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19671 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19673 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19675 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19676 for fringe update if it has periodic bitmap.
19677 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19678 and fringe_bitmap_periodic_p.
19680 * fringe.c (get_fringe_bitmap_data): New function.
19681 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19682 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19683 row. Mark glyph row for fringe update if periodicity changed.
19685 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19686 for fringe update unless it has periodic bitmap.
19688 2011-05-25 Kenichi Handa <handa@m17n.org>
19690 * xdisp.c (get_next_display_element): Set correct it->face_id for
19691 a static composition.
19693 2011-05-24 Leo Liu <sdl.web@gmail.com>
19696 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19698 * fns.c (crypto_hash_function, Fsha1): New function.
19699 (Fmd5): Use crypto_hash_function.
19700 (syms_of_fns): Add Ssha1.
19702 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19704 * gnutls.c: Remove unused macros.
19705 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19706 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19707 Remove macros that are defined and never used.
19708 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19710 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19712 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19713 (Fx_get_selection_internal): Minor cleanup.
19714 (Fx_own_selection_internal): Rename arguments for consistency with
19717 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19719 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19721 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19723 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19725 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19727 * dispnew.c (scrolling_window): Don't exclude the case that the
19728 last enabled row in the desired matrix touches the bottom boundary.
19730 2011-05-21 Glenn Morris <rgm@gnu.org>
19732 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19733 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19734 and add some more files.
19736 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19738 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19739 report_file_error introduced by the change from 2011-05-07.
19741 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19743 * systime.h (Time): Define only if emacs is defined.
19744 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19745 where the include path doesn't have X11/X.h by default. See
19746 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19748 2011-05-20 Kenichi Handa <handa@m17n.org>
19750 * composite.c (find_automatic_composition): Fix previous change.
19752 2011-05-20 Glenn Morris <rgm@gnu.org>
19754 * lisp.mk: New file, split from Makefile.in.
19755 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19756 (shortlisp): Remove.
19757 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19759 2011-05-19 Glenn Morris <rgm@gnu.org>
19761 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19762 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19763 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19764 (lisp): Set the order to that of loadup.el.
19765 (shortlisp): Make it a copy of $lisp.
19766 (SOME_MACHINE_LISP): Remove.
19767 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19768 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19770 2011-05-18 Kenichi Handa <handa@m17n.org>
19772 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19773 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19774 (find_automatic_composition): Mostly rewrite for efficiency.
19776 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19778 * makefile.w32-in: Update dependencies.
19780 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19782 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19783 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19785 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19787 Fix some integer overflow issues, such as string length overflow.
19789 * insdel.c (count_size_as_multibyte): Check for string overflow.
19791 * character.c (lisp_string_width): Check for string overflow.
19792 Use EMACS_INT, not int, for string indexes and lengths; in
19793 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19794 the resulting string length overflows an EMACS_INT; instead,
19795 report a string overflow if no precision given. When checking for
19796 precision exhaustion, use a check that cannot possibly have
19797 integer overflow. (Bug#8675)
19798 * character.h (lisp_string_width): Adjust to new signature.
19800 * alloc.c (string_overflow): New function.
19801 (Fmake_string): Use it. This doesn't change behavior, but saves
19802 a few bytes and will simplify future changes.
19803 * character.c (string_escape_byte8): Likewise.
19804 * lisp.h (string_overflow): New decl.
19806 Fixups, following up to the user-interface timestamp change.
19807 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19808 for UI timestamps, instead of unsigned long.
19809 * msdos.c (mouse_get_pos): Likewise.
19810 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19811 * w32gui.h (Time): Define by including "systime.h" rather than by
19812 declaring it ourselves. (Bug#8664)
19814 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19815 * image.c (clear_image_cache): Likewise.
19817 * term.c (term_mouse_position): Don't assume time_t wraparound.
19819 Be more systematic about user-interface timestamps.
19820 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19821 and sometimes 'EMACS_UINT', to represent these timestamps.
19822 This change causes it to use 'Time' uniformly, as that's what X uses.
19823 This makes the code easier to follow, and makes it easier to catch
19824 integer overflow bugs such as Bug#8664.
19825 * frame.c (Fmouse_position, Fmouse_pixel_position):
19826 Use Time, not unsigned long, for user-interface timestamps.
19827 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19828 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19829 * keyboard.h (last_event_timestamp): Likewise.
19830 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19831 * menu.h (xmenu_show): Likewise.
19832 * term.c (term_mouse_position): Likewise.
19833 * termhooks.h (struct input_event.timestamp): Likewise.
19834 (struct terminal.mouse_position_hook): Likewise.
19835 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19836 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19837 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19838 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19839 what it was before.
19840 * menu.h, termhooks.h: Include "systime.h", for Time.
19842 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19843 Don't assume that the difference between two unsigned long values
19844 can fit into an integer. At this point, we know button_down_time
19845 <= event->timestamp, so the difference must be nonnegative, so
19846 there's no need to cast the result if double-click-time is
19847 nonnegative, as it should be; check that it's nonnegative, just in
19848 case. This bug is triggered when events are more than 2**31 ms
19849 apart (about 25 days). (Bug#8664)
19851 * xselect.c (last_event_timestamp): Remove duplicate decl.
19852 (x_own_selection): Remove needless cast to unsigned long.
19854 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19855 that always fit in int. Use a sentinel instead of a counter, to
19856 avoid a temp and to allay GCC's concerns about possible int overflow.
19857 * frame.h (struct frame): Use int for menu_bar_items_used
19858 instead of EMACS_INT, since it always fits in int.
19860 * menu.c (grow_menu_items): Check for int overflow.
19862 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19864 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19865 Before, the code was not consistent. These values cannot exceed
19866 2**31 - 1 so there's no need to make them unsigned.
19867 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19868 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19869 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19871 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19873 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19874 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19875 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19876 presumably because the widths might not match.
19878 * window.c (size_window): Avoid needless test at loop start.
19880 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19882 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19884 2011-05-12 Drew Adams <drew.adams@oracle.com>
19886 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19888 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19890 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19891 `width' to `bar_area_x' and `bar_area_width', respectively.
19892 (x_scroll_run): Take account of fringe background extension.
19894 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19895 Rename local vars `left' and `width' to `bar_area_x' and
19896 `bar_area_width', respectively.
19897 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19898 background extension.
19900 2011-05-10 Jim Meyering <meyering@redhat.com>
19902 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19904 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19906 * image.c (Finit_image_library): Return t for built-in image types,
19907 like pbm and xbm. (Bug#8640)
19909 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19911 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19913 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19915 * w32console.c (Fset_screen_color): Doc fix.
19916 (Fget_screen_color): New function.
19917 (syms_of_ntterm): Defsubr it.
19919 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19920 unlink the temporary file if Fcall_process didn't create it in the
19922 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19923 child process will be redirected to a file specified with `:file'.
19924 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19925 cue to call_process_cleanup not to close that handle.
19927 2011-05-07 Ben Key <bkey76@gmail.com>
19929 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19930 one of two shell specific rules, either bootstrap-temacs-CMD or
19931 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19932 to the previous implementation of the bootstrap-temacs rule.
19933 The bootstrap-temacs-CMD rule is similar to the previous
19934 implementation of the bootstrap-temacs rule except that it
19935 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19938 These changes, along with some changes to nt/configure.bat,
19939 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19940 earlier fix to add support for --cflags and --ldflags options
19941 that include quotes so that it works whether make uses cmd or
19944 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19946 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19947 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19949 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19950 a string. Handle both cases.
19951 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19952 (Fdbus_register_method): Use Qinvalid_function.
19954 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19956 * makefile.w32-in: Update dependencies.
19957 (LISP_H): Add inttypes.h and stdin.h.
19958 (PROCESS_H): Add unistd.h.
19960 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19962 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19963 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19965 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19967 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19969 * term.c (vfatal): Remove stray call to va_end.
19970 It's not needed and the C Standard doesn't allow it here anyway.
19972 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19973 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19975 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19978 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19980 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19982 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19984 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19986 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19988 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19989 * charset.c (Fdefine_charset_internal): Don't initialize
19990 charset.code_space[15]. The value was garbage, on hosts with
19991 32-bit int (Bug#8600).
19993 * lread.c (read_integer): Be more consistent with string-to-number.
19994 Use string_to_number to do the actual conversion; this avoids
19995 rounding errors and fixes some other screwups. Without this fix,
19996 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19997 (digit_to_number): Move earlier, for benefit of read_integer.
19998 Return -1 if the digit is out of range for the base, -2 if it is
19999 not a digit in any supported base. (Bug#8602)
20001 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20003 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20004 to match comment at start of function. This also removes a
20005 GCC warning about overflow in a 32+64-bit port.
20007 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20009 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20010 Reported by Stefan Monnier in
20011 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20012 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20013 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20015 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20016 (EMACS_UINTPTR): Likewise, with uintptr_t.
20018 * lisp.h: Prefer 64-bit EMACS_INT if available.
20019 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20020 on 32-bit hosts that have 64-bit int, so that they can access
20022 However, temporarily disable this change unless the temporary
20023 symbol WIDE_EMACS_INT is defined.
20025 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20027 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20028 This removes an assumption that EMACS_INT and long are the same
20029 width as pointers. The assumption is true for Emacs porting targets
20030 now, but we want to make other targets possible.
20031 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20032 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20033 In the rest of the code, change types of integers that hold casted
20034 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20035 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20036 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20037 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20038 No need to cast type when ORing.
20039 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20040 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20041 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20042 assume EMACS_INT is the same width as char *.
20043 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20044 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20045 Remove no-longer-needed casts.
20046 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20047 (xg_tool_bar_help_callback, xg_make_tool_item):
20048 Use EMACS_INTPTR to hold an integer
20049 that will be cast to void *; this can avoid a GCC warning
20050 if EMACS_INT is not the same width as void *.
20051 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20052 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20053 (current_message_1, set_message_1):
20054 Use a local to convert to proper width without a cast.
20055 * xmenu.c (dialog_selection_callback): Likewise.
20057 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20058 Also, don't assume VALBITS / RAND_BITS is less than 5,
20059 and don't rely on undefined behavior when shifting a 1 left into
20061 * lisp.h (get_random): Change signature to match.
20063 * lread.c (hash_string): Use size_t, not int, for hash computation.
20064 Normally we prefer signed values; but hashing is special, because
20065 it's better to use unsigned division on hash table sizes so that
20066 the remainder is nonnegative. Also, size_t is the natural width
20067 for hashing into memory. The previous code used 'int', which doesn't
20068 retain enough info to hash well into very large tables.
20069 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20071 * dbusbind.c: Don't possibly lose pointer info when converting.
20072 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20073 Use XPNTR rather than XHASH, so that the high-order bits of
20074 the pointer aren't lost when converting through void *.
20076 * eval.c (Fautoload): Don't double-shift a pointer.
20078 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20080 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20082 * gnutls.c (DEF_GNUTLS_FN):
20083 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20085 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20087 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20090 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20092 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20093 New version that can reserve upto 2GB of heap space.
20095 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20097 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20099 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20101 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20102 `gnutls_certificate_set_x509_key_file'.
20104 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20106 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20107 Update dependencies.
20109 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20111 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20112 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20113 Remove unused parameter `fildes'.
20114 * process.c (read_process_output, send_process): Don't pass it.
20116 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20118 Fix previous change: the library cache is defined in w32.c.
20119 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20120 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20122 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20124 Implement dynamic loading of GnuTLS on Windows.
20126 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20127 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20128 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20131 * gnutls.c (Qgnutls_dll): Define.
20132 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
20133 (gnutls_*): Declare function pointers.
20134 (init_gnutls_functions): New function to initialize function pointers.

20137 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20138 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
20139 (emacs_gnutls_write, emacs_gnutls_read)
20140 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20141 (Fgnutls_available_p): New function.
20142 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

20150 (w32_delayed_load): Move to w32.c.
20152 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20154 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20155 (w32_delayed_load): Move from image.c. When loading a library, record
20156 its filename in the :loaded-from property of the library id.
20157 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20158 Initialize and staticpro them.
20159 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20161 * process.c: Include lisp.h before w32.h, not after.
20162 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20163 instead of gnutls_record_check_pending.
20165 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20167 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20169 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20170 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20173 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20175 * xterm.c (x_set_frame_alpha): Do not set property on anything
20176 else than FRAME_X_OUTER_WINDOW (Bug#8608).
20178 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20180 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
20182 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20184 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

20198 * sysdep.c (wait_for_termination_1): Make static.
20199 (wait_for_termination, interruptible_wait_for_termination):
20200 Move after wait_for_termination_1.
20202 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
20204 * sysdep.c (interruptible_wait_for_termination): New function
20205 which is like wait_for_termination, but allows keyboard
20208 * callproc.c (Fcall_process): Add (:file "file") as an option for
20210 (Fcall_process_region): Ditto.
20212 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20214 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20215 rather than `XVECTOR (FOO)->size'.
20217 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20218 inttypes.h, as a gnulib replacement is used if it not available in
20221 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20223 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20224 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20225 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20227 * coding.c (coding_alloc_by_realloc): Error out if destination
20228 will grow beyond MOST_POSITIVE_FIXNUM.
20229 (decode_coding_emacs_mule): Abort if there isn't enough place in
20230 charbuf for the composition carryover bytes. Reserve an extra
20231 space for up to 2 characters produced in a loop.
20232 (decode_coding_iso_2022): Abort if there isn't enough place in
20233 charbuf for the composition carryover bytes.
20235 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20237 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
20238 aborting when %lld or %lll format is passed.
20239 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20240 %llo or %llx format is passed. (Bug#8545)
20242 * window.c (window_scroll_line_based): Use a marker instead of
20243 simple variables to record original value of point. (Bug#7952)
20245 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20246 produced by %s or %c overflows available buffer space. (Bug#8545)
20248 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20250 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

20257 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20259 * keyboard.c (Qdelayed_warnings_hook): Define.
20260 (command_loop_1): Run `delayed-warnings-hook'
20261 if Vdelayed_warnings_list is non-nil.
20262 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20263 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20265 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20267 * doprnt.c (doprnt): Don't return value smaller than the buffer
20268 size if the message was truncated. (Bug#8545).
20270 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20272 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20273 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20275 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20277 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20279 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20281 * makefile.w32-in: Update dependencies.
20283 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20285 Improve `doprnt' and its usage. (Bug#8545)
20286 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20287 `format_end'. Remove support for %l as a conversion specifier.
20288 Don't use xrealloc. Improve diagnostics when the %l size modifier
20289 is used. Update the commentary.
20291 * eval.c (verror): Simplify calculation of size_t.
20293 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20296 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20298 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20301 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20303 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20304 This makes this file independent of the recent pseudovector change.
20306 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20308 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20310 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20311 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20312 Remove unused local.
20313 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20315 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20316 GCC 4.6.0 optimizes based on type-based alias analysis.
20317 For example, if b is of type struct buffer * and v of type struct
20318 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20319 != &v->size, and therefore "v->size = 1; b->size = 2; return
20320 v->size;" must therefore return 1. This assumption is incorrect
20321 for Emacs, since it type-puns struct Lisp_Vector * with many other
20322 types. To fix this problem, this patch adds a new type struct
20323 vectorlike_header that documents the constraints on layout of vectors
20324 and pseudovectors, and helps optimizing compilers not get fooled
20325 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20326 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20327 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20329 (XSETPVECTYPE): Rewrite in terms of new macro.
20330 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20331 This is a bit clearer, and further avoids the possibility of
20332 undesirable aliasing.
20333 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20334 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20335 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20336 since Lisp_Subr is a special case (no "next" field).
20337 (ASIZE): Now uses header.size rather than size.
20338 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20339 to avoid the hassle of writing XVECTOR (foo)->header.size.
20340 (struct vectorlike_header): New type.
20341 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20342 object, to help avoid aliasing.
20343 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20344 (SUBRP): Likewise, since Lisp_Subr is a special case.
20345 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20346 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20347 (struct Lisp_Hash_Table): Combine first two members into a single
20348 struct vectorlike_header member. All uses of "size" and "next" members
20349 changed to be "header.size" and "header.next".
20350 * buffer.h (struct buffer): Likewise.
20351 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20352 * frame.h (struct frame): Likewise.
20353 * process.h (struct Lisp_Process): Likewise.
20354 * termhooks.h (struct terminal): Likewise.
20355 * window.c (struct save_window_data, struct saved_window): Likewise.
20356 * window.h (struct window): Likewise.
20357 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20358 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20359 * buffer.c (init_buffer_once): Likewise.
20360 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20362 * process.c (Fformat_network_address): Use local var for size,
20365 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20367 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20368 * data.c (atof): Remove decl; no longer used or needed.
20369 (digit_to_number): Move to lread.c.
20370 (Fstring_to_number): Use new string_to_number function, to be
20371 consistent with how the Lisp reader treats infinities and NaNs.
20372 Do not assume that floating-point numbers represent EMACS_INT
20373 without losing information; this is not true on most 64-bit hosts.
20374 Avoid double-rounding errors, by insisting on integers when
20375 parsing non-base-10 numbers, as the documentation specifies.
20376 * lisp.h (string_to_number): New decl, replacing ...
20377 (isfloat_string): Remove.
20378 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20379 (read1): Do not accept +. and -. as integers; this
20380 appears to have been a coding error. Similarly, do not accept
20381 strings like +-1e0 as floating point numbers. Do not report
20382 overflow for integer overflows unless the base is not 10 which
20383 means we have no simple and reliable way to continue.
20384 Break out the floating-point parsing into a new
20385 function string_to_number, so that Fstring_to_number parses
20386 floating point numbers consistently with the Lisp reader.
20387 (digit_to_number): Move here from data.c. Make it static inline.
20388 (E_CHAR, EXP_INT): Remove, replacing with ...
20389 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20390 (string_to_number): New function, replacing isfloat_string.
20391 This function checks for valid syntax and produces the resulting
20392 Lisp float number too. Rework it so that string-to-number
20393 no longer mishandles examples like "1.0e+". Use strtoumax,
20394 so that overflow for non-base-10 numbers is reported only when
20395 there's no portable and simple way to convert to floating point.
20397 * textprop.c (set_text_properties_1): Rewrite for clarity,
20398 and to avoid GCC warning about integer overflow.
20400 * intervals.h (struct interval): Use EMACS_INT for members
20401 where EMACS_UINT might cause problems. See
20402 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20403 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20404 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20406 (offset_intervals): Tell GCC not to worry about length overflow
20407 when negating a negative length.
20409 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20410 (overrun_check_free): Likewise.
20412 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20413 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20416 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20417 (gnutls_make_error): Rename local to avoid shadowing.

20420 Comment out unused local. Fix pointer signedness problems.
20422 * lread.c (openp): Don't stuff size_t into an 'int'.
20423 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20424 about possible signed overflow.
20426 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20427 (GDK_KEY_g): Don't define if already defined.
20428 (xg_prepare_tooltip): Avoid pointer signedness problem.
20429 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20431 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20432 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20434 * xfns.c (Fx_window_property): Simplify a bit,
20435 to make a bit faster and to avoid GCC 4.6.0 warning.
20436 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20438 * fns.c (internal_equal): Don't assume size_t fits in int.
20440 * alloc.c (compact_small_strings): Tighten assertion a little.
20442 Replace pEd with more-general pI, and fix some printf arg casts.
20443 * lisp.h (pI): New macro, generalizing old pEd macro to other
20444 conversion specifiers. For example, use "...%"pI"d..." rather
20445 than "...%"pEd"...".
20446 (pEd): Remove. All uses replaced with similar uses of pI.
20447 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20448 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20449 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20450 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.

20452 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20453 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20455 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20456 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20457 * print.c (safe_debug_print, print_object): Likewise.
20458 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20460 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20461 avoiding the 0 flag, which is not portable.
20462 * process.c (Fmake_network_process): Use pI to avoid cast.
20463 * region-cache.c (pp_cache): Likewise.
20464 * xdisp.c (decode_mode_spec): Likewise.
20465 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20466 behavior on 64-bit hosts with printf arg.
20467 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20468 (x_stop_queuing_selection_requests): Likewise.
20469 (x_get_window_property): Don't truncate byte count to an 'int'
20472 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20473 here, since it parses constructs like leading '-' and spaces,
20474 which are not wanted; and it overflows with large numbers.
20475 Instead, simply match F[0-9]+, which is what is wanted anyway.
20477 * alloc.c: Remove unportable assumptions about struct layout.
20478 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20479 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20480 (allocate_vectorlike, make_pure_vector): Use the new macros,
20481 plus offsetof, to remove unportable assumptions about struct layout.
20482 These assumptions hold on all porting targets that I know of, but
20483 they are not guaranteed, they're easy to remove, and removing them
20484 makes further changes easier.
20486 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20487 This doesn't fix a bug but makes the code clearer.
20488 (string_overrun_cookie): Now const. Use initializers that
20489 don't formally overflow signed char, to avoid warnings.
20490 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20491 can cause Emacs to crash when string overrun checking is enabled.
20492 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20493 multiple of sizeof (EMACS_INT); it need not be, if
20494 alignof(EMACS_INT) < sizeof (EMACS_INT).
20495 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20497 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

20526 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20527 "cast to pointer from integer of different size".
20529 Improve doprnt and its use in verror. (Bug#8545)
20530 * doprnt.c (doprnt): Document the set of format control sequences
20531 supported by the function. Use SAFE_ALLOCA instead of always
20534 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20535 is one byte too soon. Don't use xrealloc; instead xfree and
20538 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20540 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

20546 parameters of `gnutls-boot' and documented those parameters in the
20547 docstring. Start callback support.
20548 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20549 unless a fatal error occurred. Call gnutls_alert_send_appropriate

20627 conversions. Support %l conversion. Don't assume an EMACS_INT
20628 argument for integer conversions and for %c.

20653 codepoint of an invalid character, to avoid displaying a bogus
20656 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
20657 `error', not SYMBOL_NAME itself.

20662 * charset.c (check_iso_charset_parameter): Fix incorrect argument
20663 to `error' in error message about FINAL_CHAR argument. Make sure
20664 FINAL_CHAR is a character, and use %c when it is passed as
20665 argument to `error'.
20667 2011-04-23 Eli Zaretskii <eliz@gnu.org>
20669 * s/ms-w32.h (localtime): Redirect to sys_localtime.
20671 * w32.c: Include <time.h>.

20731 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
20732 by pacifying GCC about it. Maybe it's time to retire it?
20733 * xfaces.c (USG, __TIMEVAL__): Likewise.
20735 * dispextern.h (struct redisplay_interface): Rename param
20736 to avoid shadowing.
20737 * termhooks.h (struct terminal): Likewise.
20738 * xterm.c (xembed_send_message): Likewise.
20740 * insdel.c (make_gap_smaller): Define only if
20741 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
20743 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
20746 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
20747 so that we aren't warned about unused symbols.

20784 compatible char. Avoid the old compiler warnings about
20785 out-of-range initializers by using, for example, '\xab' rather
20788 * xgselect.c (xgselect_initialize): Check vs interface
20789 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

20839 (group_in_compile_stack, re_search, re_search_2, regex_compile)
20840 (re_compile_pattern, re_exec): Declare arguments and local
20841 variables `size_t' and `ssize_t' and return values `regoff_t', as

20849 specify buffer/string position and length are now ssize_t and
20850 size_t. Return type is regoff_t.
20852 2011-04-16 Ben Key <bkey76@gmail.com>
20854 * nsfont.m: Fixed bugs in ns_get_family and
20855 ns_descriptor_to_entity that were caused by using free to
20856 deallocate memory blocks that were allocated by xmalloc (via
20857 xstrdup). This caused Emacs to crash when compiled with
20858 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
20859 --enable-checking=xmallocoverrun). xfree is now used to
20860 deallocate these memory blocks.

21287 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21288 Mark functions with DEFUE instead of DEFUN,
21289 if they are used in other modules.
21290 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21291 decls for now-static functions.
21292 * buffer.h (Fdelete_overlay): Remove decl.
21293 * callproc.c (Fgetenv_internal): Mark as internal.

21301 * fileio.c (Fmake_symbolic_link): New forward static decl.
21302 * image.c (Finit_image_library): New forward static decl.
21303 * insdel.c (Fcombine_after_change_execute): Make forward decl static.

21328 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21330 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21331 when at ZV. (Bug#8487)
21333 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21335 * charset.c (Fclear_charset_maps): Use xfree instead of free.
21337 * keyboard.c (parse_tool_bar_item): Likewise.
21338 * sound.c (sound_cleanup, alsa_close): Likewise.
21339 * termcap.c (tgetent): Likewise.
21340 * xfns.c (x_default_font_parameter): Likewise.
21341 * xsettings.c (read_and_apply_settings): Likewise.
21343 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21344 (overrun_check_free): Protoize.
21346 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21348 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21349 since callers should never pass a negative size.
21350 Change the signature to match that of plain 'read' and 'write'; see
21351 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21352 * lisp.h: Update prototypes of emacs_write and emacs_read.
21354 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21356 * xdisp.c (redisplay_window): Don't try to determine the character
21357 position of the scroll margin if the window start point w->startp
21358 is outside the buffer's accessible region. (Bug#8468)
21360 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21362 Fix write-region and its subroutines for buffers > 2GB.
21363 * fileio.c (a_write, e_write): Modify declaration of arguments and
21364 local variables to support buffers larger than 2GB.
21365 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21367 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21368 argument, local variables, and return value.
21370 * lisp.h: Update prototypes of emacs_write and emacs_read.
21372 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21374 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21376 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21378 Fix more problems found by GCC 4.6.0's static checks.
21380 * xdisp.c (vmessage): Use a better test for character truncation.
21382 * charset.c (load_charset_map): <, not <=, for optimization,
21383 and to avoid potential problems with integer overflow.
21384 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21385 * casetab.c (set_identity, shuffle): Likewise.
21386 * editfns.c (Fformat): Likewise.
21387 * syntax.c (skip_chars): Likewise.
21389 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21390 This also lets GCC 4.6.0 generate slightly better loop code.
21392 * callint.c (Fcall_interactively): <, not <=, for optimization.
21393 (Fcall_interactively): Count the number of arguments produced,
21394 not the number of arguments given. This is simpler and lets GCC
21395 4.6.0 generate slightly better code.
21397 * ftfont.c: Distingish more carefully between FcChar8 and char.
21398 The previous code passed unsigned char * to a functions like
21399 strlen and xstrcasecmp that expect char *, which does not
21400 conform to the C standard.
21401 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21402 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21403 char * when the C standard requires it.
21405 * keyboard.c (read_char): Remove unused var.
21407 * eval.c: Port to Windows vsnprintf (Bug#8435).
21408 Include <limits.h>.
21409 (SIZE_MAX): Define if the headers do not.
21410 (verror): Do not give up if vsnprintf returns a negative count.
21411 Instead, grow the buffer. This ports to Windows vsnprintf, which
21412 does not conform to C99. Problem reported by Eli Zaretskii.
21413 Also, simplify the allocation scheme, by avoiding the need for
21414 calling realloc, and removing the ALLOCATED variable.
21416 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21418 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21419 But keep the doprint source code for now, as we might revamp it
21420 and use it again (Bug#8435).
21421 * lisp.h (doprnt): Remove.
21422 * Makefile.in (base_obj): Remove doprnt.o.
21423 * deps.mk (doprnt.o): Remove.
21425 error: Print 32- and 64-bit integers portably (Bug#8435).
21426 Without this change, on typical 64-bit hosts error ("...%d...", N)
21427 was used to print both 32- and 64-bit integers N, which relied on
21428 undefined behavior.
21429 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21430 * lisp.h (error, verror): Mark as printf-like functions.
21431 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21432 Report overflow in size calculations when allocating printf buffer.
21433 Do not truncate output string at its first null byte.
21434 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21435 Truncate the output at a character boundary, since vsnprintf does not
21437 * charset.c (check_iso_charset_parameter): Convert internal
21438 character to string before calling 'error', since %c now has the
21440 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21441 overflow when computing char to be passed to 'error'. Do not
21442 pass Lisp_Object to 'error'; pass the integer instead.
21443 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21444 formatted with plain %d.
21446 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21448 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21450 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21452 * xterm.c (x_catch_errors): Remove duplicate declaration.
21454 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21456 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21458 2011-04-10 Jim Meyering <meyering@redhat.com>
21460 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21461 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21462 return ssize_t not "int", and use size_t as the buffer length.
21463 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21464 * gnutls.h: Update declarations.
21465 * process.c (read_process_output): Use ssize_t, to match.
21466 (send_process): Likewise.
21468 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21470 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21472 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21474 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21475 Use unsigned char, to match FcChar8 type definition.
21477 * xterm.c (handle_one_xevent):
21478 * xmenu.c (create_and_show_popup_menu):
21479 * xselect.c (x_decline_selection_request)
21480 (x_reply_selection_request): Avoid type-punned deref of X events.
21482 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21484 Fix some uses of `int' instead of EMACS_INT.
21485 * search.c (string_match_1, fast_string_match)
21486 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21487 (scan_buffer, find_next_newline_no_quit)
21488 (find_before_next_newline, search_command, Freplace_match)
21489 (Fmatch_data): Make some `int' variables be EMACS_INT.
21491 * xdisp.c (display_count_lines): 3rd argument and return value now
21492 EMACS_INT. All callers changed.
21493 (pint2hrstr): Last argument is now EMACS_INT.
21495 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21496 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21497 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

21508 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21509 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21511 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21512 (encode_invocation_designation): Last argument P_NCHARS is now
21514 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21515 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21517 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21520 * ccl.c (Fccl_execute_on_string): Declare some variables
21523 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21525 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21527 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21529 * process.c (Fformat_network_address): Doc fix.
21531 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21533 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21535 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21537 * keyboard.c (read_char): Call Lisp function help-form-show,
21538 instead of using internal_with_output_to_temp_buffer.
21539 (Qhelp_form_show): New var.
21540 (syms_of_keyboard): Use DEFSYM macro.
21542 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21544 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21546 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21548 * process.c (Flist_processes): Remove to Lisp.
21549 (list_processes_1): Delete.
21551 2011-04-06 Eli Zaretskii <eliz@gnu.org>
21553 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21555 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21557 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21559 Fix more problems found by GCC 4.6.0's static checks.
21561 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
21563 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21565 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21567 * xdisp.c (vmessage): Mark as a printf-like function.
21569 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21571 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21573 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21574 printf-like functions.
21575 (tiff_load): Add casts to remove these marks before passing them
21576 to system-supplied API.
21578 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21580 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21581 This avoids several warnings with gcc -Wstrict-overflow.
21582 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21583 directly, rather than having caller test rule sign. This avoids
21584 some unnecessary tests.
21585 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21586 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21587 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21589 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21590 (xfont_open): Avoid unnecessary tests.
21592 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21594 * composite.h, composite.c (composition_gstring_put_cache):
21595 Use EMACS_INT, not int, for length.

21598 breaking out part of COMPOSITION_DECODE_RULE.
21599 (COMPOSITION_DECODE_RULE): Use it.

21601 by using the new macro.
21603 * textprop.c (set_text_properties_1): Change while to do-while,
21604 since the condition is always true at first.
21606 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21607 (interval_deletion_adjustment): Return unsigned value.
21610 * process.c (list_processes_1, create_pty, read_process_output):

21620 (update_syntax_table): Use unsigned instead of int.
21622 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21623 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21624 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21626 * print.c (print_error_message): Avoid int overflow.
21628 * font.c (font_list_entities): Redo for clarity,
21629 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21631 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21632 (font_score): Avoid potential overflow in diff calculation.
21634 * fns.c (substring_both): Remove var that is set but not used.
21635 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21637 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21639 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21640 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21641 can always succeed if overflow has undefined behavior.
21643 * search.c (boyer_moore, wordify): Remove vars set but not used.
21644 (wordify): Omit three unnecessary tests.
21646 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21647 All callers changed. This avoids the need for an unused var.
21649 * casefiddle.c (casify_region): Remove var that is set but not used.
21651 * dired.c (file_name_completion): Remove var that is set but not used.
21653 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21655 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21656 (Finsert_file_contents): Remove unnecessary code checking fd.
21658 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21659 Check for integer overflow on size calculations.
21661 * buffer.c (Fprevious_overlay_change): Remove var that is set
21664 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21665 Remove vars that are set but not used.
21666 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21667 (timer_check_2): Mark vars as initialized.
21669 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21671 * image.c (lookup_image): Remove var that is set but not used.
21672 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21674 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21675 that are set but not used.
21677 * xfns.c (make_invisible_cursor): Don't return garbage
21678 if XCreateBitmapFromData fails (Bug#8410).
21680 * xselect.c (x_get_local_selection, x_handle_property_notify):
21681 Remove vars that are set but not used.
21683 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21684 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21686 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21687 Remove var that is set but not used.
21688 (scroll_bar_windows_size): Now size_t, not int.
21689 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21690 Check for overflow.
21692 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21693 (map_tty_color) [!defined MSDOS]: Likewise.
21695 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21697 * coding.c: Remove vars that are set but not used.
21698 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21699 All callers changed.
21700 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21701 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21702 (decode_coding_charset): Remove vars that are set but not used.
21704 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21705 that is set but not used.
21707 * print.c (print_object): Remove var that is set but not used.
21709 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21710 The gnulib version avoids calling malloc in the usual case,
21711 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21712 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21713 * filelock.c (current_lock_owner): Likewise.
21714 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21715 * sysdep.c: Include allocator.h, careadlinkat.h.
21716 (emacs_no_realloc_allocator): New static constant.
21717 (emacs_readlink): New function.
21718 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21719 ../lib/careadlinkat.h.
21721 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21723 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

21733 * xdisp.c (display_count_lines): Remove parameter `start',
21734 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

21740 (get_per_char_metric): Remove parameter `f', unused since
21741 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21743 2011-04-02 Jim Meyering <meyering@redhat.com>
21745 do not dereference NULL upon failed strdup
21746 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21747 (ns_get_family): Likewise.
21749 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21751 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21753 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21755 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21758 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21760 Add lexical binding.
21762 * window.c (Ftemp_output_buffer_show): New fun.
21763 (Fsave_window_excursion):
21764 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21766 * lread.c (lisp_file_lexically_bound_p): New function.
21767 (Fload): Bind Qlexical_binding.
21768 (readevalloop): Remove `evalfun' arg.
21769 Bind Qinternal_interpreter_environment.
21770 (Feval_buffer): Bind Qlexical_binding.
21771 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21773 (syms_of_lread): Declare `lexical-binding'.
21775 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21777 * keyboard.c (eval_dyn): New fun.
21778 (menu_item_eval_property): Use it.
21780 * image.c (parse_image_spec): Use Ffunctionp.
21782 * fns.c (concat, mapcar1): Accept byte-code-functions.
21784 * eval.c (Fsetq): Handle lexical vars.
21785 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21786 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21787 (FletX, Flet): Obey lexical binding.
21788 (Fcommandp): Handle closures.
21789 (Feval): New `lexical' arg.
21790 (eval_sub): New function extracted from Feval. Use it almost
21791 everywhere where Feval was used. Look up vars in lexical env.
21793 (Ffunctionp): Move from subr.el.
21794 (Ffuncall): Handle closures.
21795 (apply_lambda): Remove `eval_flags'.
21796 (funcall_lambda): Handle closures and new byte-code-functions.
21797 (Fspecial_variable_p): New function.
21798 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21799 but without exporting it to Lisp.
21801 * doc.c (Fdocumentation, store_function_docstring):
21802 * data.c (Finteractive_form): Handle closures.
21804 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21807 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21809 (exec_byte_code): New function extracted from Fbyte_code to handle new
21810 calling convention for byte-code-functions. Add new byte-codes.
21812 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21814 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21816 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21818 * xdisp.c (redisplay_internal): Fix prototype.
21820 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21822 * xdisp.c (SCROLL_LIMIT): New macro.
21823 (try_scrolling): Use it when setting scroll_limit.
21824 Limit scrolling to 100 screen lines.
21825 (redisplay_window): Even when falling back on "recentering",
21826 position point in the window according to scroll-conservatively,
21827 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21829 (try_scrolling): When point is above the window, allow searching
21830 as far as scroll_max, or one screenful, to compute vertical
21831 distance from PT to the scroll margin position. This prevents
21832 try_scrolling from unnecessarily failing when
21833 scroll-conservatively is set to a value slightly larger than the
21834 window height. Clean up the case of PT below the margin at bottom
21835 of window: scroll_max can no longer be INT_MAX. When aggressive
21836 scrolling is in use, don't let point enter the opposite scroll
21837 margin as result of the scroll.
21838 (syms_of_xdisp) <scroll-conservatively>: Document the
21839 threshold of 100 lines for never-recentering scrolling.
21841 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21843 * dispextern.h (move_it_by_lines):
21844 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21845 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21846 (message_log_check_duplicate): Remove parameters `prev_bol' and
21847 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21848 (redisplay_internal): Remove parameter `preserve_echo_area',
21849 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21851 * indent.c (Fvertical_motion):
21852 * window.c (window_scroll_pixel_based, Frecenter):
21853 Don't pass `need_y_p' to `move_it_by_lines'.
21855 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21857 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21858 steal a few bits to be more compact.
21859 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21860 Remove unneeded casts.
21862 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21864 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21866 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21867 binding" message (bug#7967).
21869 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21871 Fix more problems found by GCC 4.6.0's static checks.
21873 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21874 Remove unused local var.
21876 * editfns.c (Fmessage_box): Remove unused local var.
21878 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21879 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21880 Omit unused local vars.
21881 * window.c (shrink_windows): Omit unused local var.
21882 * menu.c (digest_single_submenu): Omit unused local var.
21883 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21884 Omit unused local var.
21886 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21887 Don't assume string length fits in int.
21888 (keyremap_step, read_key_sequence): Use size_t for sizes.
21889 (read_key_sequence): Don't check last_real_key_start redundantly.
21891 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21892 instead of alloca (Bug#8344).
21894 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21895 (Fbacktrace_frame): Don't assume nframes fits in int.
21897 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

21902 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21904 * cm.c (calccost): Turn while-do into do-while, for clarity.
21906 * keyboard.c (syms_of_keyboard): Use the same style as later
21907 in this function when indexing through an array. This also
21908 works around GCC bug 48267.
21910 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21912 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21914 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21915 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21917 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21918 This avoids undefined behavior on integer overflow, and is a bit
21919 more convenient anyway since it is compared to a size_t variable.
21921 Variadic C functions now count arguments with size_t, not int.
21922 This avoids an unnecessary limitation on 64-bit machines, which
21923 caused (substring ...) to crash on large vectors (Bug#8344).

21933 * fns.c (concat): Likewise.
21934 * frame.c (x_set_frame_parameters): Likewise.
21935 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21936 0 if not found, not -1. All callers changed.
21938 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21939 (stack_copy_size): Now size_t, not int.
21940 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21942 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21944 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',

21961 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21962 don't set the hook to nil, but remove the offending function instead.
21963 (Qcommand_hook_internal): Remove, unused.
21964 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21965 Vcommand_hook_internal.
21967 * eval.c (enum run_hooks_condition): Remove.
21968 (funcall_nil, funcall_not): New functions.
21969 (run_hook_with_args): Call each function through a `funcall' argument.

21971 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21972 (Frun_hook_with_args_until_failure): Adjust accordingly.
21973 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

21996 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.

22146 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22148 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22149 unconditionally since it does the check itself.
22151 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22153 Fix more problems found by GCC 4.5.2's static checks.
22155 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22156 the first time through the loop, since we know p0 < p1 then.
22157 This also avoids a gcc -Wstrict-overflow warning.
22159 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22160 leading to a memory leak, possible in functions like
22161 load_charset_map_from_file that can allocate an unbounded number
22162 of objects (Bug#8318).
22164 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22165 that could (at least in theory) be that large.
22167 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22168 This is less likely to overflow, and avoids undefined behavior if
22169 overflow does occur. All callers changed. Use strtoul to scan
22170 for the unsigned long integer.
22171 (pint2hrstr): Simplify and tune code slightly.
22172 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22174 * scroll.c (do_scrolling): Work around GCC bug 48228.
22175 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

22180 This also avoids a warning with gcc -Wstrict-overflow.
22182 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22185 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22187 * process.c (Fmake_network_process): Use socklen_t, not int,
22188 where POSIX says socklen_t is required in portable programs.
22189 This fixes a porting bug on hosts like 64-bit HP-UX, where
22190 socklen_t is wider than int (Bug#8277).
22191 (Fmake_network_process, server_accept_connection):
22192 (wait_reading_process_output, read_process_output):
22195 * process.c: Rename or move locals to avoid shadowing.

22205 Make tparam.h and terminfo.c consistent.
22206 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22207 Include tparam.h instead, since it declares them.
22208 * cm.h (PC): Remove extern decl; tparam.h now does this.
22209 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22210 * terminfo.c: Include tparam.h, to check interfaces.
22211 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22212 (tparam): Adjust signature to match interface in tparam.h;
22213 this removes some undefined behavior. Check that outstring and len
22214 are zero, which they always are with Emacs.
22215 * tparam.h (PC, BC, UP): New extern decls.
22217 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22218 (xftfont_open): Rename locals to avoid shadowing.
22220 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

22236 (composition_update_it): Mark var as initialized.
22237 (find_automatic_composition): Mark vars as initialized,
22238 with a FIXME (Bug#8290).

22244 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22245 to avoid shadowing.
22247 * textprop.c (property_change_between_p): Remove; unused.
22249 * intervals.c (interval_start_pos): Now static.
22251 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

22256 * sound.c (wav_play, au_play, Fplay_sound_internal):
22257 Fix pointer signedness.
22258 (alsa_choose_format): Remove unused local var.
22259 (wav_play): Initialize a variable to 0, to prevent undefined
22260 behavior (Bug#8278).
22262 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22264 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22266 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22267 clobbering (Bug#8298).
22268 * sysdep.c (sys_subshell): Likewise.
22269 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22271 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22272 This should get cleaned up, so that child_setup has the
22273 same signature on all platforms.
22275 * callproc.c (call_process_cleanup): Now static.
22276 (relocate_fd): Rename locals to avoid shadowing.
22278 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22280 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22281 not to be necessary, and produces flickering.
22283 2011-03-20 Glenn Morris <rgm@gnu.org>
22285 * config.in: Remove file.
22287 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
22289 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
22290 are now in src/globals.h.
22291 (syms_of_minibuf): Remove spurious & from previous change.

22301 * xfaces.c (Fx_load_color_file):
22302 Read color file from absolute filename (bug#8250).
22304 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
22306 * makefile.w32-in: Update dependencies.
22308 2011-03-17 Eli Zaretskii <eliz@gnu.org>
22310 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

22317 (sigchld_handler): Now static.
22319 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
22320 That way, the code declares only the vars that it needs.

22330 (CONSTANTLIM): Remove; unused.
22331 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
22332 Define only if needed.
22334 * unexelf.c (unexec): Name an expression,
22335 to avoid gcc -Wbad-function-cast warning.
22336 Use a different way to cause a compilation error if anyone uses
22337 n rather than nn, a way that does not involve shadowing.
22338 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22340 * deps.mk (unexalpha.o): Remove; unused.
22342 New file unexec.h, the (simple) interface for unexec (Bug#8267).
22343 * unexec.h: New file.
22344 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
22345 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
22346 Depend on unexec.h.
22347 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
22348 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
22349 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
22350 Change as necessary to match prototype in unexec.h.
22352 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

22397 * callint.c (quotify_arg, quotify_args): Now static.
22398 (Fcall_interactively): Rename locals to avoid shadowing.

22405 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
22406 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22407 some of which prompt warnings from gcc -Wbad-function-cast.
22408 (Fformat_time_string, Fencode_time, Finsert_char):
22409 (Ftranslate_region_internal, Fformat):
22410 Rename or remove local vars to avoid shadowing.

22413 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
22416 * lisp.h (eassert): Check that the argument compiles, even if
22417 ENABLE_CHECKING is not defined.
22419 * data.c (Findirect_variable): Name an expression, to avoid
22420 gcc -Wbad-function-cast warning.
22421 (default_value, arithcompare, arith_driver, arith_error): Now static.

22429 Rename locals to avoid shadowing.
22430 (mark_stack): Move local variables into the #ifdef region where
22432 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
22433 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
22435 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
22436 (GC_STRING_CHARS): Remove; not used.
22437 (Fmemory_limit): Cast sbrk's returned value to char *.
22439 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
22440 avoids undefined behavior in theory.
22442 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22444 Use functions, not macros, for up- and down-casing (Bug#8254).
22445 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22446 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22447 to use the following functions instead of these macros.
22448 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22449 EMACS_INT, since callers assume the returned value fits in int.
22450 (upcase1): Likewise, for UPCASE_TABLE.
22451 (uppercasep, lowercasep, upcase): New static inline functions.
22452 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22461 which gcc can warn about.
22462 (regex_compile, re_match_2_internal): Mark locals as initialized.
22463 (RETALLOC_IF): Define only if needed.
22464 (WORDCHAR_P): Likewise. This one is never needed, but is used
22465 only in a comment talking about a compiler bug, so put inside
22466 the #if 0 of that comment.
22467 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22468 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
22471 * search.c (boyer_moore): Rename locals to avoid shadowing.
22472 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

22494 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22495 New macros, so that the caller can use some names other than
22496 gcpro1, gcpro2, etc.
22497 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22499 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22500 argument, for consistency with GCPRO2_VAR, etc: it is now the
22501 prefix of the variable, not the variable itself. All uses
22503 * dired.c (directory_files_internal, file_name_completion):
22504 Rename locals to avoid shadowing.
22506 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22507 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22508 dired.c's scmp function, had undefined behavior.
22509 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22510 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22511 * buffer.h: ... to here, because these macros use current_buffer,
22512 and the new implementation with inline functions needs to have
22513 current_buffer in scope now, rather than later when the macros
22515 (downcase, upcase1): New static inline functions.
22516 (DOWNCASE, UPCASE1): Reimplement using these functions.
22517 This avoids undefined behavior in expressions like
22518 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22519 from race conditions in accessing the global variables
22520 case_temp1 and case_temp2.
22521 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22522 * lisp.h (case_temp1, case_temp2): Remove their decls.
22523 * character.h (ASCII_CHAR_P): Move from here ...
22524 * lisp.h: ... to here, so that the inline functions mentioned
22525 above can use them.
22527 * dired.c (directory_files_internal_unwind): Now static.
22529 * fileio.c (file_name_as_directory, directory_file_name):

22532 (file_name_as_directory): Use const pointers when appropriate.
22533 (Fexpand_file_name): Likewise. In particular, newdir might
22534 point at constant storage, so make it a const pointer.
22535 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22536 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22538 (Fset_file_times, Finsert_file_contents, auto_save_error):
22539 Rename locals to avoid shadowing.
22541 * minibuf.c (choose_minibuf_frame_1): Now static.

22543 to avoid shadowing.
22545 * marker.c (bytepos_to_charpos): Remove; unused.
22547 * lisp.h (verify_bytepos, count_markers): New decls,
22548 so that gcc does not warn that these functions aren't declared.
22550 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22551 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22552 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22553 (copy_text): Remove unused local var.
22555 * filelock.c (within_one_second): Now static.
22556 (lock_file_1): Rename local to avoid shadowing.
22558 * buffer.c (fix_overlays_before): Mark locals as initialized.
22559 (fix_start_end_in_overlays): Likewise. This function should be
22560 simplified by using pointers-to-pointers, but that's a different
22562 (switch_to_buffer_1): Now static.
22563 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22564 (report_overlay_modification): Rename locals to avoid shadowing.
22566 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22567 Fix pointer signedness issue.
22568 (sys_subshell): Mark local as volatile if checking for lint,
22569 to suppress a gcc -Wclobbered warning that does not seem to be right.
22570 (MAXPATHLEN): Define only if needed.
22572 * process.c (serial_open, serial_configure): Move decls from here ...
22573 * systty.h: ... to here, so that they can be checked.
22575 * fns.c (get_random, seed_random): Move extern decls from here ...
22576 * lisp.h: ... to here, so that they can be checked.
22578 * sysdep.c (reset_io): Now static.
22579 (wait_for_termination_signal): Remove; unused.
22581 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
22582 (copy_keymap_item, append_key, push_text_char_description):
22584 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22585 (DENSE_TABLE_SIZE): Remove; unused.
22586 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22587 (describe_map_tree):
22588 Rename locals to avoid shadowing.
22590 * keyboard.c: Declare functions static if they are not used elsewhere.
22591 (echo_char, echo_dash, cmd_error, top_level_2):
22592 (poll_for_input, handle_async_input): Now static.

22596 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
22597 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
22598 (read_key_sequence, read_char): Mark locals as initialized.

22605 * lisp.h (force_auto_save_soon): New decl.
22607 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
22608 (DEFINE_DUMMY_FUNCTION): New macro.
22609 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
22611 (main): Add casts to avoid warnings
22612 if GCC considers string literals to be constants.
