112 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
113 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
114 from Elisp via unread-command-events.

128 Use bool for boolean.
129 * region-cache.c (region_cache_forward, region_cache_backward):

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

252 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
253 * sysdep.c (list_system_processes)
254 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
255 Make it a stub in this case; otherwise the build might fail,
256 and this code hasn't been tested on such hosts anyway.
257 Problem reported by Nelson H. F. Beebe in
258 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
259 and analyzed by Jérémie Courrèges-Anglas in
260 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
262 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
264 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.

270 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
272 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
273 * filelock.c: Include <c-ctype.h>.
274 (MAX_LFINFO): New top-level constant.
275 (lock_info_type): Remove members pid, boot_time. Add members at,
276 dot, colon. Change user member to be the entire buffer, not a
277 pointer. This allows us to handle the case where a foreign
278 pid or boot time exceeds the local range. All uses changed.
279 (LINKS_MIGHT_NOT_WORK): New constant.
280 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
281 (defined_WINDOWSNT): Remove.
282 (MAKE_LOCK_NAME, file_in_lock_file_name):
283 Always use .#FILE (not .#-FILE) for the file lock,
284 even if it is a regular file.
285 (rename_lock_file): New function.
286 (create_lock_file): Use it.
287 (create_lock_file, read_lock_data):
288 Prefer a symbolic link for the lock file, falling back on a
289 regular file if symlinks don't work. Do not try to create
290 symlinks on MS-Windows, due to security hassles. Stick with
291 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
292 link, rename, unlink, mkstemp) when creating locks, as a GNUish
293 host may be using a Windowsish file system, and cannot use
294 MS-Windows-only system calls. Fall back on mktemp if mkstemp
295 doesn't work. Don't fail merely because of a symlink-contents
296 length limit in the current file system; fall back on regular
297 files. Increase the symlink contents length limit to 8 KiB, this
298 should be big enough for any real use and doesn't crunch the
300 (create_lock_file, lock_file_1, read_lock_data):
301 Simplify allocation of lock file buffers now that they fit in 8 KiB.
302 (lock_file_1): Return error number, not bool. All callers changed.
303 (ELOOP): New macro, if not already defined.
304 (read_lock_data): Return size of lock file contents, not Lisp object.
305 All callers changed. Handle a race condition if some other process
306 replaces a regular-file lock with a symlink lock or vice versa,
307 while we're trying to read the lock.
308 (current_lock_owner): Parse contents more carefully, to help avoid
309 confusing a regular-file lock with some other application's use
310 of the file. Check for lock file contents being too long, or
311 not parsing correctly.
312 (current_lock_owner, lock_file):
313 Allow foreign pid and boot times that exceed the local range.
314 (current_lock_owner, lock_if_free, lock_file):
315 Simplify allocation of lock file contents.
316 * w32.c (sys_rename_replace): New function, containing most of
317 the contents of the old sys_rename.
318 (sys_rename): Use it.
319 (fchmod): New dummy function.
320 * w32.h (sys_rename_replace, fchmod): New decls.
322 2013-03-05 Eli Zaretskii <eliz@gnu.org>
324 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
325 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
326 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
327 <dmantipov@yandex.ru>.
329 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
331 * composite.c (get_composition_id, fill_gstring_header):
332 Use make_uninit_vector where appropriate.
333 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
334 * xselect.c (clean_local_selection_data): Likewise.
336 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
338 Fix misuse of ImageMagick that caused core dump (Bug#13846).
339 * image.c (imagemagick_load_image): Calculate height and width
340 after flattening the image, not before.
342 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
344 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
345 * ftfont.c (ftfont_shape_by_flt): Likewise.
346 * w32uniscribe.c (uniscribe_shape): Likewise.
348 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
350 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
351 The old approach, which fell back on DIR/.#FILE.0 through
352 DIR/.#FILE.9, had race conditions that could not be easily fixed.
353 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
354 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
355 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
356 because the locking mechanism was never reliable in that case).
357 This patch fixes this and other bugs discovered by a code
358 inspection that was prompted by
359 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
360 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
361 to avoid interoperability problems between the MS-Windows and
362 non-MS-Windows implementations. MS-Windows and non-MS-Windows
363 instances of Emacs now ignore each others' locks.
364 * filelock.c (defined_WINDOWSNT): New constant.
365 (MAKE_LOCK_NAME, fill_in_lock_file_name):
366 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
367 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
368 regular files on MS-Windows hosts.
369 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
370 Use SAFE_ALLOCA to avoid problems with long file names.
371 (MAX_LFINFO): Now a local constant, not a global macro.
372 (IS_LOCK_FILE): Remove.
373 (lock_file_1): Don't inspect errno if symlink call succeeds;
375 (lock_file): Document that this function can return if lock
377 (lock_file): Don't access freed storage.
379 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

383 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
385 * textprop.c: Use bool for booleans.
386 (validate_interval_range, Fadd_text_properties)
387 (Fremove_text_properties): Prefer bool to int when either works.
389 2013-03-02 Eli Zaretskii <eliz@gnu.org>
391 * textprop.c (Fadd_text_properties, Fremove_text_properties):
392 If the interval tree changes as a side effect of calling
393 modify_region, re-do processing starting from the call to
394 validate_interval_range. (Bug#13743)
396 2013-02-28 Eli Zaretskii <eliz@gnu.org>
398 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
401 2013-02-27 Eli Zaretskii <eliz@gnu.org>
403 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
404 _SH_DENYRW flag, instead of emacs_open, to deny any other process
405 access to the lock file until it is written and closed.
408 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
410 * callint.c (Qcall_interactively):

418 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
420 Minor textprop integer cleanup.
421 * intervals.h, textprop.c (add_text_properties_from_list):
422 Return void, not int, since nobody uses the return value.
423 * textprop.c (validate_plist, add_properties, remove_properties)
424 (Fadd_text_properties):
425 Don't assume list length fits in int.
426 (interval_has_all_properties, interval_has_some_properties)
427 (interval_has_some_properties_list, add_properties, remove_properties)
428 (Fadd_text_properties, Fremove_text_properties)
429 (Fremove_list_of_text_properties, text_property_stickiness):
430 Use bool for booleans.
431 (Fadd_text_properties, Fremove_text_properties):
432 (Fremove_list_of_text_properties):
433 Reindent do-while as per GNU style.

437 Implement CLASH_DETECTION for MS-Windows.
439 * filelock.c [WINDOWSNT]: Include w32.h.
440 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
441 function of that name. Up-case the macro arguments.
442 (IS_LOCK_FILE): New macro.
443 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
444 (create_lock_file): New function, with body extracted from
446 [WINDOWSNT]: Implement lock files by writing a regular file with
447 the lock information as its contents.
448 (read_lock_data): New function, on Posix platforms just calls
450 [WINDOWSNT]: Read the lock info from the file.
451 (current_lock_owner): Call read_lock_data instead of calling
452 emacs_readlinkat directly.
453 (lock_file) [WINDOWSNT]: Run the file name through
456 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
457 just check if the process by that PID exists.
459 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
460 also present, as doing so will fail to error out if the file
463 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
465 * textprop.c (Fadd_text_properties, Fremove_text_properties)
466 (Fremove_list_of_text_properties): Skip all of the intervals in
467 the region between START and END that already have resp. don't
468 have the requested properties, not just the first one.
469 Add assertions that the loop afterwards always modifies the
470 properties. (Bug#13743)
472 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>

483 (START_FILES): Remove. All uses removed.
484 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
485 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.

499 (make_hdr): Use DATA_START instead of start_of_data.
500 * vm-limit.c: Move most of mem-limits.h's contents here.
501 (data_start): New decl. It's OK if this is approximate,
502 so simplify-away some unnecessary exactness.
503 (POINTER): Remove; all uses removed.
504 (data_space_start): Now char *, to avoid casts.
505 (exceeds_lisp_ptr): New function, replacing the old
506 EXCEEDS_LISP_PTR macro. All uses changed.
507 (check_memory_limits): Simplify and remove casts.
508 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

527 Assume C89 or better.
528 * ralloc.c (SIZE, POINTER, NIL):
529 * vm-limit.c (POINTER):
530 Remove, replacing all uses with C89 equivalents. These old
531 symbols were present only for porting to pre-C89 platforms.
533 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
535 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
536 This avoids warning messages reported as part of Bug#13546.
538 2013-02-21 Ken Brown <kbrown@cornell.edu>
540 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.

549 (syms_of_keyboard): Adjust accordingly.
551 2013-02-19 Daniel Colascione <dancol@dancol.org>
553 * sheap.c (report_sheap_usage): Use message, not message1, so
554 that we don't try to create a buffer while we're in the middle
555 of dumping Emacs. Explain why.
557 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
559 * search.c (find_newline): Return byte position in bytepos.

606 unconditionally. (Bug#9066)
608 * w32.c (set_errno): Reset h_errno and don't set it to any other

654 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
656 Fix AIX port (Bug#13650).
657 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
658 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
659 was #undeffed earlier, so it cannot be used as a macro here.
660 Use the constant and not the macro.
662 2013-02-15 Eli Zaretskii <eliz@gnu.org>
664 * w32proc.c (new_child): If no vacant slots are found in
665 child_procs[], make another pass looking for slots whose process

669 MAXDESC, set errno to EMFILE.
670 (_sys_read_ahead): Update cp->status when failing to read serial

672 STATUS_READ_IN_PROGRESS. (Bug#13546)
674 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
676 * gtkutil.c (tb_size_cb): New function.

681 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
684 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
686 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
688 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

696 2013-02-13 Glenn Morris <rgm@gnu.org>
698 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
700 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
702 Improve AIX port some more (Bug#13650).
703 With this, it should be as good as it was in 23.3, though it's
704 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
705 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
706 * unexaix.c (start_of_text): Remove.
707 (_data, _text): Declare as char[], not int, as AIX manual suggests.
708 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
709 (orig_load_scnptr, orig_data_scnptr):
710 Now off_t, not long, since they are file offsets.
711 (make_hdr): Use _data, not start_of_data ().
712 This is the key part of the fix.
713 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
714 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
716 * pre-crt0.c (data_start): Initialize to 1.
717 This ports to compilers that optimize the external declaration
718 'int x = 0;' as if it were 'int x;' to shrink the executable.
720 Improve AIX port (Bug#13650).
721 This doesn't fix the bug, but it makes progress: Emacs builds now.
722 * unexaix.c: Include inttypes.h, stdarg.h.
723 (report_error, report_error_1): Mark as _Noreturn.
724 (report_error): Don't report the wrong errno.
725 (report_error_1): Now varargs. All callers changed.
726 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
727 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
728 (write_ptr): Use %p to print address rather than %lx and a cast
729 to unsigned long. Grow buffer a bit, to be safer.
731 2013-02-13 Eli Zaretskii <eliz@gnu.org>
733 * bidi.c (bidi_resolve_neutral): After finding the next
734 non-neutral character, accept NEUTRAL_ON type as well, because
735 directional control characters, such as LRE and RLE, have their
736 type converted to that by bidi_resolve_weak. This avoids aborts
737 when LRE/RLE follows a run of neutrals.
738 (bidi_move_to_visually_next): Assert that return value of
739 bidi_peek_at_next_level is non-negative. Negative values will
742 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
744 Minor getenv-related fixes.
745 * callproc.c (Fcall_process_region) [!DOS_NT]:
746 Avoid unnecessary duplicate call to getenv.
747 * callproc.c (init_callproc):
748 * dispnew.c (init_display):

750 Omit unnecessary cast of getenv or egetenv.
752 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
754 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
757 2013-02-12 Eli Zaretskii <eliz@gnu.org>
759 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
761 (display_line): Set w->region_showing to the value of
762 it->region_beg_charpos, not to -1. This fixes redisplay
763 optimization when cursor is moved up after M->. (Bug#13623)
765 (try_scrolling): Scroll text up more if point is too close to ZV
766 and inside the scroll margin. This makes sure point is moved
767 outside the scroll margin in these cases.
769 * window.h (struct window): region_showing can no longer be
772 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
774 Tune by using memchr and memrchr.
775 * doc.c (Fsnarf_documentation):
776 * fileio.c (Fsubstitute_in_file_name):
777 * search.c (find_newline, scan_newline):
778 * xdisp.c (pos_visible_p, display_count_lines):
779 Use memchr and memrchr rather than scanning byte-by-byte.
780 * search.c (find_newline): Rename from scan_buffer.
781 Omit first arg TARGET, as it's always '\n'. All callers changed.
783 Clean up read_key_sequence a tiny bit more.
784 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
785 (read_key_sequence): Remove unused locals.
787 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
789 Clean up read_key_sequence a bit; reread active keymaps after first event.
790 * keyboard.c (read_char, read_char_x_menu_prompt)
791 (read_char_minibuf_menu_prompt):
792 Replace nmaps+maps with a single `map' arg.
793 (follow_key): Operate on a single map.
794 (active_maps): New function.
795 (test_undefined): Also return true for nil bindings.
796 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
797 a single (composed) keymap. Remember `first_event' to choose the right
798 set of active keymaps. Recompute the set of keymaps after receiving
799 the first event. Remove GOBBLE_FIRST_EVENT.
800 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
801 * keyboard.h (read_char): Update declaration.
802 * lread.c (read_filtered_event): Adjust call to read_char.
804 2013-02-11 Eli Zaretskii <eliz@gnu.org>
806 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
807 Don't use the limitation on backwards movement when lines are truncated
808 in the window. (Bug#13675)
810 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
812 * marker.c (set_marker_internal): If desired position is passed
813 as a marker, avoid call to buf_charpos_to_bytepos.
814 * window.c (Fset_window_point): Omit redundant type checking.
815 (Fset_window_start): Likewise. Format comment.
816 (window_scroll_pixel_based): Use set_marker_restricted_both
817 with character and byte positions obtained from an iterator.
818 (Fset_window_configuration): Use set_marker_restricted_both.
819 * xdisp.c (message_dolog): Likewise.
821 2013-02-10 Eli Zaretskii <eliz@gnu.org>
823 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
824 When text lines are longer than window's screen lines, don't move back
825 too far. This speeds up some redisplay operations. (Bug#13675)
827 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
829 * syntax.c (scan_sexps_forward): Fix byte position calculation
830 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
832 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
834 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
837 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
839 Minor hashing refactoring.
840 * fns.c (SXHASH_REDUCE): Move to lisp.h.
841 (sxhash_float): Return EMACS_UINT, for consistency with the other
843 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
844 non-static inline function and therefore can't use static vars.
845 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
846 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
847 with the other hash functions.
849 2013-02-09 Eli Zaretskii <eliz@gnu.org>
851 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
852 XXXXXX part of the temporary file pattern is not downcased even
853 when w32-downcase-file-names is non-nil. (Bug#13661)
855 * xdisp.c (decode_mode_spec): Remove handling of %t.
857 * msdos.c (careadlinkatcwd): Remove.

941 2013-02-04 Eli Zaretskii <eliz@gnu.org>
943 * xdisp.c (window_buffer_changed): region_showing can be negative,
944 which still means region is being displayed.
945 (redisplay_internal): Resurrect code that forced redisplay of the
946 whole window when showing region and the mark has changed.
947 Record the new mark position to allow redisplay optimizations.
948 (display_line): If it->region_beg_charpos is non-zero, set the
949 window's region_showing member to -1. (Bug#13623) (Bug#13626)

952 not bitfield of 1 bit.
954 2013-02-03 Daniel Colascione <dancol@dancol.org>
956 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
957 daemon mode works on cygw32 when Emacs is installed and not just
960 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
962 Avoid file time stamp bug on MS-Windows (Bug#13149).
963 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
964 as FAT32 doesn't update time stamps when truncating them.
965 Also, check that a file time stamp is not a multiple of 100 ns;
966 this should catch all instances of the problem on MS-Windows,
967 as its native file system resolution is 100 ns or worse, and
968 checking for a non-multiple of 100 ns should impose only a small
969 overhead on systems with ns resolution.
971 2013-02-02 Eli Zaretskii <eliz@gnu.org>
973 Avoid encoding file names on MS-Windows when they need to be run
974 through dostounix_filename.
975 * w32.c (normalize_filename): Accept an additional argument
976 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
977 downcase it even if w32-downcase-file-names is non-nil.
978 (dostounix_filename): Accept an additional argument MULTIBYTE and
979 pass it to normalize_filename.
980 (emacs_root_dir): Adjust.
982 * msdos.h (dostounix_filename): Adjust prototype.
984 * w32.h (dostounix_filename): Adjust prototype.
986 * msdos.c (dostounix_filename): Accept an additional argument and
988 (init_environment): Adjust callers of dostounix_filename.
990 * fileio.c (Ffile_name_directory, file_name_as_directory)
991 (directory_file_name, Fexpand_file_name)
992 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
994 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
996 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
997 variables, as egetenv is case-insensitive for DOS_NT.
999 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1000 with an encoded file name.
1002 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1003 Adjust calls to dostounix_filename.
1005 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1007 * unexw32.c (unexec): Adjust call to dostounix_filename.
1009 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1011 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1014 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1017 * callproc.c (Fcall_process): Make sure program name in PATH and
1018 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1019 is passed to exec/spawnve, which fails unless the file-name
1022 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1023 even if w32-quote-process-args is nil.
1025 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1027 Fix timestamp bug when write-region appends nothing (Bug#13149).
1028 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1029 the file's time stamp doesn't change if Emacs happens to write nothing
1030 to the file, and on a buggy file system this could cause Emacs to
1031 incorrectly infer that the file system doesn't have the bug.
1032 Avoid this problem by inhibiting the inference in this case.
1034 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1036 * window.h (struct window): Convert base_line_number, base_line_pos
1037 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1038 Convert region_showing member from Lisp_Object to bitfield.
1039 Remove sequence_number member. Adjust comments.
1040 * window.c (sequence_number): Remove.
1041 (make_window): Initialize column_number_displayed.
1042 * print.c (print_object): Follow the printed representation of
1043 frames and print window pointer to distinguish between windows.
1044 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1045 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1046 (wset_column_number_displayed, wset_region_showing): Remove.
1047 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1048 (try_scrolling, try_cursor_movement, redisplay_window)
1049 (try_window_reusing_current_matrix, try_window_id, display_line)
1050 (display_mode_lines, decode_mode_spec): Adjust users.
1051 * .gdbinit (pwinx): Do not print sequence_number.
1053 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1055 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1056 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1057 * dired.c: Include <fcntl.h>.
1058 (open_directory): New function, which uses open and fdopendir
1059 rather than opendir. DOS_NT platforms still use opendir, though.
1060 (directory_files_internal, file_name_completion): Use it.
1061 (file_attributes): New function, with most of the old Ffile_attributes.
1062 (directory_files_internal, Ffile_attributes): Use it.
1063 (file_attributes, file_name_completion_stat): First arg is now fd,
1064 not dir name. All uses changed. Use fstatat rather than lstat +
1066 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1067 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1068 (emacs_readlinkat): New function, with much of the old
1069 Ffile_symlink_p, but with an fd argument for speed.
1070 It uses readlinkat rather than careadlinkatcwd, so that it
1071 need not assume the working directory.
1072 (Ffile_symlink_p): Use it.
1073 * filelock.c (current_lock_owner): Use emacs_readlinkat
1074 rather than emacs_readlink.
1075 * lisp.h (emacs_readlinkat): New decl.
1076 (READLINK_BUFSIZE, emacs_readlink): Remove.
1077 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1078 (emacs_norealloc_allocator, emacs_readlink): Remove.
1079 This stuff is moved to fileio.c.
1080 * w32.c (fstatat, readlinkat): New functions.
1081 (careadlinkat): Don't check that fd == AT_FDCWD.
1082 (careadlinkatcwd): Remove; no longer needed.
1084 2013-01-31 Glenn Morris <rgm@gnu.org>
1086 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
1087 (Fwrite_region): Update for new choose_write_coding_system args.
1088 Move the last piece of choose_write_coding_system here. (Bug#13522)
1089 (syms_of_fileio): Add choose-write-coding-system.
1091 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1093 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1094 (sys_close): Zero out the flags for the file descriptor before
1095 closing it. (Bug#13546)
1097 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1098 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1099 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1102 * w32.c (w32_get_long_filename, init_environment, readlink):
1103 Support file names encoded in DBCS codepages.
1104 (readlink): Use the current file-name-coding-system, not the ANSI
1105 codepage, to decode and handle targets of symlinks.
1107 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1109 * w32.c (opendir): Now accepts a 'const char *'.
1111 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1113 Remove obsolete redisplay code. See the discussion at
1114 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1115 * dispnew.c (preemption_period, preemption_next_check): Remove.
1116 (Vredisplay_preemption_period): Likewise.
1117 (update_frame, update_single_window, update_window, update_frame_1):
1118 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1119 used, following the 2012-06-22 change.
1121 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1123 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1125 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1127 * font.c (num_fonts): Remove the leftover from old
1128 debugging code. Adjust comment style here and there.
1129 * insdel.c (insert_1): Remove.
1130 * lisp.h (insert_1): Remove prototype.
1131 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1133 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1135 * w32.c (max_filename_mbslen): New function.
1136 (normalize_filename, readdir): Use it to detect locales where ANSI
1137 encoding of file names uses a double-byte character set (DBCS).
1138 If a DBCS encoding is used, advance by characters using
1139 CharNextExA, instead of incrementing a 'char *' pointer.
1140 Use _mbslwr instead of _strlwr. (Bug#13515)
1142 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1143 request of memory reservation to 1.7GB. (Bug#13065)
1145 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1147 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1148 at check_extra_latin label. (Bug#13505)
1150 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1152 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1153 Avoid redundant calls to strlen.
1155 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1157 Drop async_visible and async_iconified fields of struct frame.
1158 This is possible because async input is gone; for details, see
1159 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1160 * frame.h (struct frame): Remove async_visible and async_iconified
1161 members, convert garbaged to unsigned bitfield. Adjust comments.
1162 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1163 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1164 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1165 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1166 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1168 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1169 properly. Likewise for obscured.
1171 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1174 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1176 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1178 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1179 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1181 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1183 * xdisp.c (message2, message2_nolog): Remove functions.
1184 (message3, message3_nolog): Extract nbytes and multibyteness directly
1185 from the string. Change all callers.
1186 (message3_nolog): Don't set message_enable_multibyte since set_message
1187 will reset it anyway.
1188 (message1, message1_nolog): Use message3.
1189 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1190 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1191 (set_message): Drop all but the second arg, which has to be a string.
1192 (set_message_1): Simplify now that we know that a1 is NULL and the
1193 second arg is a string.
1194 * frame.h (struct frame): Remove `message_buf' field.
1195 Use glyphs_initialized_p instead.
1196 (FRAME_MESSAGE_BUF): Remove macro.
1197 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1198 * lisp.h (message2, message2_nolog): Remove declarations.
1199 (message3, message3_nolog): Update declarations.
1200 * keyboard.c (read_char_minibuf_menu_text)
1201 (read_char_minibuf_menu_width): Remove vars.
1202 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1203 to correctly handle multibyte strings.
1204 * frame.c (delete_frame): Don't free message_buf any more.
1205 * editfns.c (message_text, message_length): Remove vars.
1206 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1207 * fileio.c (auto_save_error): Use message3 instead of message2.
1208 * dispnew.c (adjust_frame_message_buffer): Remove function.
1210 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1212 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1213 real estate used for the tool bar and the menu bar.
1215 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1217 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1218 hidden buffer is prepared to modification (Bug#13164).
1220 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1222 * window.h (struct window): Change window_end_valid member from
1223 Lisp_Object to a bitfield. Adjust comments.
1224 (wset_window_end_valid): Remove.
1225 * window.c (adjust_window_count): Clear window_end_valid.
1226 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1227 (Fwindow_line_height, set_window_buffer, Frecenter)
1228 (Fsplit_window_internal, Fdelete_other_windows_internal)
1229 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1230 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1231 * xdisp.c (check_window_end, reconsider_clip_changes)
1232 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1233 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1234 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1236 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1238 * xdisp.c (mark_window_display_accurate): Simplify the loop
1239 assuming that the only one of vchild, hchild or buffer window
1240 slots is non-nil. Call mark_window_display_accurate_1 for
1241 the leaf windows only.
1242 (mark_window_display_accurate_1): Always assume leaf window.
1245 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1247 * emacs.c (Qkill_emacs_hook): Now static.
1249 * fileio.c (Finsert_file_contents): Simplify.
1250 Remove unnecessary assignments and tests.
1252 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1254 * w32.c (acl_set_file): Don't test for errors unless
1255 set_file_security returns FALSE. Avoids spurious errors when
1258 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1260 * fileio.c (Finsert_file_contents): Revert code introduced at
1261 2013-01-18 in favor of the simpler and generally better fix.
1262 Save stack space by removing 'buffer' and reusing 'read_buf'
1265 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1267 * lisp.h (eabs): Define unconditionally (Bug#13419).
1268 The old "#if !defined (eabs)" was an unnecessary revenant of back
1269 when this macro was called "abs". Document 'eabs' better.
1271 2013-01-19 Glenn Morris <rgm@gnu.org>
1273 * fns.c (Frandom): Doc fix.
1275 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1277 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1278 segfault when there are lots of overlays.
1280 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1281 when there are lots of overlays.
1282 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1283 for the details and a way to reproduce.
1285 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1287 * fileio.c: Use O_APPEND to append.
1288 This corresponds better to the natural interpretation of "append",
1289 and avoids the need to open the output file twice, or to invoke
1290 lseek when APPEND is neither nil nor a number.
1291 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1292 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1293 file possibly twice, and lseeking to its end; this avoids the
1294 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1295 at the same time: the combination is never needed and apparently
1296 it doesn't work with DOS_NT.
1298 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1299 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1301 Allow floating-point file offsets.
1302 Problem reported by Vitalie Spinu in
1303 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1304 * fileio.c (emacs_lseek): Remove.
1305 (file_offset): New function.
1306 (Finsert_file_contents, Fwrite_region): Use it.
1308 2013-01-19 Chong Yidong <cyd@gnu.org>
1310 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1311 aborting on Fsignal (Bug#13289).
1313 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1315 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1316 set_file_security as failure due to insufficient privileges.
1317 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1318 (fstat): Return owner and group like 'stat' and 'lstat' do.
1320 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1322 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1323 The bug was observed on Ubuntu operating inside a virtual machine,
1324 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1325 The workaround introduces a race condition on non-buggy hosts,
1326 but it's an unlikely race and anyway there's a nearly identical
1327 nearby race that can't be fixed.
1328 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1330 (Fwrite_region): Test for file system time stamp bug.
1331 (init_fileio): New function.
1332 * lisp.h (init_fileio): Declare it.
1333 * emacs.c (main): Call it.
1335 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1336 and make it more consistent with other stat-failure diagnostics.
1338 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1340 Fix crash when inserting data from non-regular files.
1341 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1342 for the error description produced by valgrind.
1343 * fileio.c (read_non_regular): Rename to read_contents.
1344 Free Lisp_Save_Value object used to pass parameters.
1345 (read_non_regular_quit): Rename to read_contents_quit.
1346 (Finsert_file_contents): Redesign internal file reading loop to adjust
1347 gap and end positions after each read and so help make_gap to work
1348 properly. Do not signal an I/O error too early and so do not leave
1349 not yet decoded characters in a buffer, which was the reason of
1350 redisplay crash. Use list2 to build return value. Adjust comments.
1352 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1354 Close a race when statting and reading files (Bug#13149).
1355 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1356 This avoids a race if the file is renamed between stat and open.
1357 This race is not the problem originally noted in Bug#13149;
1358 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1360 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
1362 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
1363 objects, related functions and macros.
1364 (make_save_value): Adjust prototype.
1365 (make_save_pointer): New prototype.
1366 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
1367 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1368 * alloc.c (format_save_value): Rename to make_save_value.
1369 (make_save_pointer): New function.
1370 (record_xmalloc): Use make_save_pointer.
1371 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1372 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1373 Change users of make_save_value to make_save_pointer.
1374 Likewise for format_save_value and make_save_value.
1376 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
1378 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
1379 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.
1380 * buffer.c (toplevel, syms_of_buffer): Drop old commented-out
1383 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
1385 * alloc.c (free_save_value): Now static.
1387 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1389 * keymap.c (map_keymap_internal): Use format_save_value.
1390 (map_keymap_char_table_item): Adjust accordingly.
1391 * fileio.c (non_regular_fd, non_regular_inserted)
1392 (non_regular_nbytes): Remove.
1393 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1394 Use format_save_value to pass parameters to read_non_regular.
1395 (read_non_regular): Use XSAVE_ macros to extract parameters.
1397 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1399 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1401 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1403 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1404 extraction from any Lisp_Save_Value slot. Add type checking.

1459 (save_excursion_restore): Adjust to match new layout. Use free_misc
1460 because we do not allocate extra memory any more. Add eassert.
1461 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1462 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

1476 Fix SIGDANGER handlers, for AIX (Bug#13408).
1477 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:

1530 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1532 Avoid unnecessary byte position calculation for the gap movement.

1544 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1546 * term.c (init_tty): Use them instead of rolling our own code.
1547 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1548 switches from 'signal' to 'pthread_sigmask', which is safer in
1549 multithreaded applications.
1550 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1551 which has already arranged for that.
1552 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1553 This is the main part of the bug fix.

1565 predicate, which is how it's really used now. Adjust comment.
1566 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1567 * buffer.c (buffer_slot_type_mismatch): Remove.
1568 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1569 predicate. Adjust comment.

1572 left-margin-width, right-margin-width, left-fringe-width,
1573 right-fringe-width, scroll-bar-width and buffer-display-count.
1574 Use Qstringp for default-directory, buffer-file-name,
1575 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1576 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1578 * data.c (store_symval_forwarding): Adjust to call the predicate.

1595 (make_gap_1): New function to adjust the gap of any buffer.
1596 * coding.c (coding_alloc_by_making_gap): Use it.
1597 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,

1626 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1627 digits for buffer positions, before misalignment starts.
1628 Display "0" for integer "object" field.
1629 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1630 Display the newline glyph more unambiguously.
1632 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1634 * nsterm.m (ns_draw_underwave):
1635 * w32term.c (w32_draw_underwave):
1636 * xterm.c (x_draw_underwave): Make underwave look more triangular
1637 and also degrade gracefully for small fonts. (Bug#13000)
1639 * nsterm.m (ns_draw_text_decoration):
1640 * w32term.c (x_draw_glyph_string):
1641 * xterm.c (x_draw_glyph_string): Don't use previous underline
1642 thickness and position if previous underline type is underwave.
1644 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1646 * fileio.c (Ffile_acl): Undocument return format.
1648 2013-01-02 Glenn Morris <rgm@gnu.org>
1650 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

1660 * lread.c (read_list):
1661 * minibuf.c (Ftry_completion):
1662 * term.c (tty_ins_del_lines):
1663 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
1664 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
1666 2012-12-31 Eli Zaretskii <eliz@gnu.org>
1668 * w32.c (unsetenv): Set up the string passed to _putenv
1670 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
1671 for the bug this caused.
1673 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
1675 * coding.c (Qmac): Now static.
1677 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
1679 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
1680 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

1687 by TOOLBAR_TOP_WIDGET.
1688 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
1689 Check toolbar_is_packed.
1690 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
1691 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1692 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1694 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1695 (xg_update_menubar): Update title only if
1696 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1697 (xg_update_submenu): Skip tearoff only if
1698 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1699 (xg_initialize): Initialize xg_detached_menus only if
1700 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1702 * xterm.h (struct x_output): Surround handlebox_widget with
1703 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1704 toolbar_in_hbox is bool.
1706 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1708 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1709 (LIBS_GNUSTEP): Define.
1710 (LIBES): Add $(LIBS_GNUSTEP).
1711 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1713 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1715 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1716 continuation glyph on a TTY with an indication of an empty line.
1719 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1721 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1722 file's SELinux context or ACLs successfully set, nil otherwise.
1724 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1726 * w32proc.c (reader_thread): Avoid passing NULL handles to
1727 SetEvent and WaitForSingleObject.
1729 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1731 Port EXTERNALLY_VISIBLE to Clang 3.2.
1732 * conf_post.h (__has_attribute): New macro.
1733 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1735 2012-12-27 Glenn Morris <rgm@gnu.org>
1737 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1738 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1740 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1742 * fileio.c (file_name_as_directory, directory_file_name):
1743 Accept an additional argument MULTIBYTE to indicate whether the input C
1744 came from a multibyte or a unibyte Lisp string; all callers
1745 adjusted. Don't assume the input string is always multibyte.
1747 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1748 don't ENCODE_FILE them, and return a unibyte string if the input
1750 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1751 don't assume the input strings will always be multibyte. If the
1752 input strings are multibyte, decode strings obtained from C
1755 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1757 * lisp.h (toplevel): Add two notices to the comment about
1758 defining a new Lisp data type.

1762 * alloc.c (valid_lisp_object_p): Adjust comment.
1764 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1766 * keyboard.c (record_asynch_buffer_change): Initialize an event
1767 only if it's really needed.
1768 * frame.h (enum output_method): Remove output_mac member since
1769 it's a leftover from the deleted code.
1770 * frame.c (Fframep): Adjust user here ...
1771 * terminal.c (Fterminal_live_p): ... and here.
1772 * coding.c (Qmac): Now here because it's only used to denote
1773 end-of-line encoding type.
1774 (syms_of_coding): DEFSYM it.
1775 * frame.h (Qmac): Remove duplicated declaration.
1777 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1779 * window.c (select_window_1): Now static, since it's used only here.
1781 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1783 * window.c (window_body_cols): Subtract display margins from the
1784 window body width on TTYs as well. See
1785 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1786 for the original report.
1788 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1790 * xdisp.c (redisplay_window): Remove inner local variable
1791 because the outer shadowed one has the same meaning.
1792 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1794 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1795 (xg_create_tool_bar): Adjust users.
1797 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1799 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1800 * buffer.c (Fget_buffer_create): Use it to set compact field of
1801 struct buffer_text to avoid accessing an uninitialized value
1802 when compact_buffer is called for the first time.
1803 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1804 (Fset_buffer_modified_p): Use buffer_window_count to check
1805 whether the buffer is displayed in some window.
1806 * xdisp.c (message_dolog): Likewise.
1808 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1810 * w32.c (acl_set_file): If setting the file security descriptor
1811 fails, and the new DACL is identical to the existing one, silently
1812 return success. This fixes problems for users backing up their
1813 own files without having the necessary privileges for setting
1814 security descriptors.
1816 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1818 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1819 after WaitForSingleObject returns normally. This expedites reader
1820 thread shutdown when delete_child triggers it.
1821 (reap_subprocess): More accurate commentary for why we call
1822 delete_child only when cp->fd is negative.
1824 * w32.c (sys_close): Do not call delete_child on a subprocess
1825 whose handle is not yet closed. Instead, set its file descriptor
1826 to a negative value, so that reap_subprocess will call
1827 delete_child on that subprocess when its SIGCHLD arrives.
1828 This avoids closing handles used for communications between sys_select
1829 and reader_thread, which doesn't give sys_select a chance to
1830 notice that the process exited and invoke the SIGCHLD handler for
1833 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1835 * nsfns.m (Fns_do_applescript): Run event loop until script has
1836 been executed (Bug#12969).
1837 (ns_run_ascript): Chech as_script for nil, set to nil after
1840 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1842 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1844 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1846 * w32term.c (w32fullscreen_hook): New function.
1847 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1849 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1851 * fileio.c (Finsert_file_contents): Doc fix.
1853 * w32proc.c (new_child, delete_child, find_child_pid): For a
1854 subprocess, consider its slot being in use as long as its process
1855 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1856 slot when a new process is started immediately after killing
1857 another one, without waiting enough time for the first process to
1858 be reaped and resources allocated for it be orderly freed.
1860 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1862 2012-12-21 Chong Yidong <cyd@gnu.org>
1864 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1866 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1868 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1870 * w32.c (get_name_and_id): Always pass NULL as the first argument
1871 of lookup_account_sid. Avoids crashes with UNC file names that
1872 refer to DFS domains, not to specific machine names. (Bug#12621)

1968 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1970 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1971 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1972 for some of that bug's symptoms can now cause Emacs to abort.
1973 Remove the workaround.
1974 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1975 The bug that caused SIGCHLD to get lost has been fixed, and the

2026 delete the file, record it as pending deletion when the subprocess

2056 * dired.c (Ffile_attributes) [WINDOWSNT]:
2057 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2058 owner and group information from 'lstat'.

2062 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2063 as that confuses set-auto-coding, so insist on the head-read

2092 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2094 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.

2096 Remove unnecessary S_ISLNK test, as (contra the comments) this
2097 function can't copy symlinks. Improve quality of error message
2098 when attempting to copy files that are neither regular files nor

2117 * inotify.c (inotify_callback): Generate an Emacs event for every
2118 incoming inotify event.

2122 * xdisp.c (handle_face_prop): Fix logic of computing
2123 it->start_of_box_run_p.

2127 iterator's start_of_box_run_p flag before prepending the stretch.

2351 * lisp.h (xputenv): New decl.
2353 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
2355 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
2357 2012-12-08 Eli Zaretskii <eliz@gnu.org>
2359 * w32.c (unsetenv, sys_putenv): New functions.
2361 2012-12-08 Chong Yidong <cyd@gnu.org>
2363 * editfns.c (Finsert_char): Make the error message more
2364 informative (Bug#12992).
2366 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2368 Simplify get_lim_data.
2369 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2370 Remove USG and vlimit methods; no longer used these days.
2371 Add #error catchall just in case.
2373 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2374 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2375 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
2376 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
2377 (deleted_pid_list, Fdelete_process, create_process)
2378 (record_child_status_change, handle_child_signal, deliver_child_signal)
2379 (init_process_emacs, syms_of_process):
2380 Assume SIGCHLD is defined.
2381 (parse_signal): Remove. All uses removed.
2382 (abbr_to_signal): New static function.
2383 (Fsignal_process): Use it to convert signal names to ints.
2384 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
2385 kill (getpgrp (), ...).
2386 (emacs_sigaction_init): Assume SIGCHLD is defined.
2387 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
2388 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
2389 * syssignal.h (EMACS_KILLPG): Remove.
2390 All uses replaced by 'kill' with a negative pid.
2391 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
2392 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
2394 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
2396 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
2397 This will cause a production Emacs to dump core instead of
2400 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2402 * frame.c (make_frame): Do not set window's buffer to t.
2403 * window.c (Fsplit_window_internal): Likewise. Previously it was
2404 used to indicate that the window is being set up. Now we use
2405 set_window_buffer for all new windows, so the condition in ...
2406 (Fset_window_buffer): ... is always true and can be removed.
2408 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2410 Convenient macro to check whether the buffer is hidden.
2411 * buffer.h (BUFFER_HIDDEN_P): New macro.
2412 * frame.c (make_frame): Use it. Adjust comment.
2413 * buffer.c (candidate_buffer): New function.
2414 (Fother_buffer, other_buffer_safely): Use it.
2416 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2418 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2419 if the child process is still running. Instead, exit the wait
2420 loop and return zero. (Bug#13086)
2422 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2424 * frame.h (x_char_width, x_char_height): Remove prototypes.
2425 * w32term.h (x_char_width, x_char_height): Likewise.
2426 * xfns.c (x_char_width, x_char_height): Remove.
2427 * w32fns.c (x_char_width, x_char_height): Likewise.
2428 * nsfns.c (x_char_width, x_char_height): Likewise.
2429 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
2431 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
2432 * keyboard.c (command_loop_1): Remove prototype.

2435 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
2437 Fix a recently-introduced delete-process race condition.
2438 * callproc.c, process.h (record_kill_process):
2439 New function, containing part of the old call_process_kill.
2440 (call_process_kill): Use it.
2441 This does not change call_process_kill's behavior.
2442 * process.c (Fdelete_process): Use record_kill_process to fix a
2443 race condition that could cause Emacs to lose track of a child.
2445 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2447 Avoid code duplication between prev_frame and next_frame.
2448 * frame.c (candidate_frame): New function. Add comment.
2449 (prev_frame, next_frame): Use it. Adjust comment.
2451 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2453 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2454 fails, signal an error instead of continuing with an empty
2456 Encode expanded temp file pattern before passing it to mkstemp or
2459 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2460 Encode the file name before passing it to dostounix_filename, in
2461 case it will downcase it (under w32-downcase-file-names).
2464 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2466 Minor call-process cleanups.
2467 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2468 at the same time as other platforms, to simplify analysis.
2469 No need for fd0_volatile since we have synch_process_fd.
2470 Avoid needless emacs_close; arg is always negative.
2472 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2474 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2477 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2479 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2480 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2481 and mouse_face_hidden members to a bitfields.
2482 * frame.h (struct frame): Remove set-but-not-used space_width member.
2483 (FRAME_SPACE_WIDTH): Remove.
2484 * nsterm.m, w32term.c, xterm.c: Adjust users.
2485 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2486 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2487 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2488 members to a bitfields.
2490 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2492 Don't let call-process be a zombie factory (Bug#12980).
2493 Fixing this bug required some cleanup of the signal-handling code.
2494 As a side effect, this change also fixes a longstanding rare race
2495 condition whereby Emacs could mistakenly kill unrelated processes,
2496 and it fixes a bug where a second C-g does not kill a recalcitrant
2497 synchronous process in GNU/Linux and similar platforms.
2498 The patch should also fix the last vestiges of Bug#9488,
2499 a bug which has mostly been fixed on the trunk by other changes.
2500 * callproc.c, process.h (synch_process_alive, synch_process_death)
2501 (synch_process_termsig, sync_process_retcode):
2502 Remove. All uses removed, to simplify analysis and so that
2503 less consing is done inside critical sections.
2504 * callproc.c (call_process_exited): Remove. All uses replaced
2505 with !synch_process_pid.
2506 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2507 These take the role of what used to be in unwind-protect arg.
2509 (block_child_signal, unblock_child_signal):
2510 New functions, to avoid races that could kill innocent-victim processes.
2511 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2512 (call_process_kill): Record killed processes as deleted, so that
2513 zombies do not clutter up the system. Do this inside a critical
2514 section, to avoid a race that would allow the clutter.
2515 (call_process_cleanup): Fix code so that the second C-g works again
2516 on common platforms such as GNU/Linux.
2517 (Fcall_process): Create the child process in a critical section,
2518 to fix a race condition. If creating an asynchronous process,
2519 record it as deleted so that zombies do not clutter up the system.
2520 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2521 light of these changes. Omit unnecessary call to emacs_close
2522 before failure, as the unwind-protect code does that.
2523 * callproc.c (call_process_cleanup):
2524 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2525 * process.c (record_deleted_pid): New function, containing
2526 code refactored out of Fdelete_process.
2527 (Fdelete_process): Use it.
2528 (process_status_retrieved): Remove. All callers changed to use
2529 child_status_change.
2530 (record_child_status_change): Remove, folding its contents into ...
2531 (handle_child_signal): ... this signal handler. Now, this
2532 function is purely a handler for SIGCHLD, and is not called after
2533 a synchronous waitpid returns; the synchronous code is moved to
2534 wait_for_termination. There is no need to worry about reaping
2535 more than one child now.
2536 * sysdep.c (get_child_status, child_status_changed): New functions.
2537 (wait_for_termination): Now takes int * status and bool
2538 interruptible arguments, too. Do not record child status change;
2539 that's now the caller's responsibility. All callers changed.
2540 Reimplement in terms of get_child_status.
2541 (wait_for_termination_1, interruptible_wait_for_termination):
2542 Remove. All callers changed to use wait_for_termination.
2543 * syswait.h: Include <stdbool.h>, for bool.
2544 (record_child_status_change, interruptible_wait_for_termination):
2546 (record_deleted_pid, child_status_changed): New decls.
2547 (wait_for_termination): Adjust to API changes noted above.
2549 * bytecode.c, lisp.h (Qbytecode): Remove.
2550 No longer needed after 2012-11-20 interactive-p changes.
2552 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2554 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2555 the scroll margin, move point outside the margin. (Bug#13055)
2557 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2559 * gtkutil.c (my_log_handler): New function.
2560 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2562 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2564 * lisp.h (modify_region): Rename to...
2565 (modify_region_1): ...new prototype.
2566 * textprop.c (modify_region): Now static. Adjust users.
2567 * insdel.c (modify_region): Rename to...
2568 (modify_region_1): ...new function to work with current buffer.
2569 Adjust comment and users. Use true and false for booleans.
2571 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2573 * alloc.c (free_save_value): New function.
2574 (safe_alloca_unwind): Use it.
2575 * lisp.h (free_save_value): New prototype.
2576 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2578 (save_excursion_restore): Adjust to match saved data structure.
2579 Use free_save_value to offload some work from GC. Drop obsolete
2582 2012-12-03 Chong Yidong <cyd@gnu.org>
2584 * fileio.c (Vauto_save_list_file_name): Doc fix.
2586 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2588 * w32fns.c: Remove prototype of atof.
2589 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2591 (file_dialog_callback): Make it UINT_PTR.
2593 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2596 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2597 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2600 2012-12-03 Glenn Morris <rgm@gnu.org>
2602 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2604 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2606 Fix xpalloc confusion after memory is exhausted.
2607 * alloc.c (xpalloc): Comment fix.
2608 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2609 and signals an error, do not clear charset_table_size, as
2610 charset_table is still valid.
2611 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2613 Use execve to avoid need to munge environ (Bug#13054).
2614 * callproc.c (Fcall_process):
2615 * process.c (create_process):
2616 Don't save and restore environ; no longer needed.
2617 * callproc.c (child_setup):
2618 Use execve, not execvp, to preserve environ.
2620 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2622 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2624 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2626 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2627 display for sliced images (Bug#10500).
2629 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2631 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2633 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2634 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2636 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2638 * xdisp.c (window_outdated): Remove eassert since it hits
2639 some suspicious corner cases (see Bug#13007 and Bug#13012).
2640 (mode_line_update_needed): New function.
2641 (redisplay_internal, redisplay_window): Use it.
2642 (ensure_selected_frame): New function.
2643 (redisplay_internal, unwind_redisplay): Use it.
2644 (redisplay_internal): Move comment about buffer_shared...
2645 (buffer_shared_and_changed): ...near to its real use.
2647 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2649 * callproc.c (Fcall_process): Don't misreport vfork failure.
2651 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2653 * callproc.c (Fcall_process): Fix vfork portability problems.
2654 Do not assume that fd[0], count, filefd, and save_environ survive
2655 vfork. Fix bug whereby wrong errno value could be reported for
2656 pipe failure. Some minor cleanups, too, as follows. Move buf and
2657 bufsize to the context where they're needed. Change new_argv to
2658 be of type char **, as this is more convenient and avoids casts.
2659 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2660 Now local constants, not macros.
2662 2012-11-18 Kenichi Handa <handa@gnu.org>
2664 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2665 for the variable "f".
2667 2012-11-13 Kenichi Handa <handa@gnu.org>
2669 * font.c (font_unparse_xlfd): Exclude special characters from the
2670 generating XLFD name.
2672 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
2674 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

2685 * lread.c (readbyte_from_file): Assume EINTR is defined.
2686 * process.c (wait_reading_process_output, send_process) [subprocesses]:
2687 Assume EIO and EAGAIN are defined.
2688 * unexcoff.c (write_segment): Assume EFAULT is defined.
2690 2012-11-27 Eli Zaretskii <eliz@gnu.org>
2692 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
2695 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2696 highlighting on the frame was cleared. Prevents assertion
2697 violations when repeatedly clicking on the "Top" link of the
2698 "bread-crumbs" in Info buffers.
2700 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
2702 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
2704 2012-11-24 Ken Brown <kbrown@cornell.edu>
2706 * keyboard.c (HAVE_MOUSE):
2707 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2708 were always defined.
2710 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2712 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2713 between bpos_covered and bpos_max. This fixes cursor display when
2714 several display strings follow each other.
2716 * .gdbinit (pgx): If the glyph's object is a string, display the
2717 pointer to string data, rather than the value of the string object
2718 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2720 * indent.c (Fvertical_motion): If the starting position is covered
2721 by a display string, return to one position before that, to avoid
2722 overshooting it inside move_it_to. (Bug#12930)
2724 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2726 * frame.h (struct frame): Remove display_preempted member

2729 * w32menu.c (pending_menu_activation): Remove since not
2731 (set_frame_menubar): Adjust user.
2732 * w32term.h (struct x_output): Drop outdated #if 0 code.
2733 (struct w32_output): Use bitfields for explicit_parent,
2734 asked_for_visible and menubar_active members.
2735 Drop unused pending_menu_activation member.
2736 * xterm.h (struct x_output): Drop outdated #if 0 code.
2737 Use bitfields for explicit_parent, asked_for_visible,
2738 has_been_visible and net_wm_state_hidden_seen members.

2742 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2743 of a literal "/". (Bug#12955)
2744 (gl-stamp): Invoke fc.exe directly, not through cmd.
2746 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

2749 * dired.c: Assume HAVE_DIRENT_H.
2750 (NAMLEN): Remove, replacing with ...
2751 (dirent_namelen): New function. All uses changed. Use the GNU macro
2752 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2753 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2754 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2755 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2757 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2758 * ndir.h: Rename to ../nt/inc/dirent.h.
2759 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2760 Do not include <dirent.h>; no longer needed.
2761 * w32.c: Include <dirent.h> rather than "ndir.h".
2763 2012-11-23 Chong Yidong <cyd@gnu.org>
2765 * xftfont.c (xftfont_open): Remove duplicate assignment.
2767 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2769 * alloc.c (Fgarbage_collect): Unblock input after clearing
2770 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2771 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2772 * msdos.c (IT_frame_up_to_date): Use it here...
2773 * w32term.c (w32_frame_up_to_date): ...here...
2774 * xterm.c (XTframe_up_to_date): ...and here...
2775 * nsterm.m (ns_frame_up_to_date): ...but not here.
2776 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2778 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2779 Do not check whether GC is in progress.
2781 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2783 * xdisp.c (window_buffer_changed): New function.
2784 (update_menu_bar, update_tool_bar): Use it to
2785 simplify large 'if' statements.
2786 (redisplay_internal): Generalize commonly used
2787 'tail' and 'frame' local variables.
2789 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2791 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2792 with Windows system header.
2794 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2796 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2797 * alloc.c: Assume unistd.h exists.

2801 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2802 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2803 * w32.h (getcwd): Remove decl.
2805 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>

2808 Make it set selected_window as well.
2809 (update_tool_bar): Use it.
2811 2012-11-21 Ken Brown <kbrown@cornell.edu>
2813 * emacs.c (main): Set the G_SLICE environment variable for all
2814 Cygwin builds, not just GTK builds. See
2815 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2817 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2819 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2820 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2821 Define for the MSVC compiler.
2823 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2825 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2826 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2827 dostounix_filename. Prevents crashes down the road, because
2828 dostounix_filename assumes it gets a unibyte string.
2829 Reported by Michel de Ruiter <michel@sentient.nl>, see
2830 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
2832 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2834 Conflate Qnil and Qunbound for `symbol-function'.
2835 * alloc.c (Fmake_symbol): Initialize `function' to Qnil.
2836 * lread.c (init_obarray): Set `function' fields to Qnil.
2837 * eval.c (Fcommandp): Ignore Qunbound.
2838 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2839 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2840 Test NILP rather than Qunbound.
2841 (Ffmakunbound): Set to Qnil.
2842 (Fsymbol_function): Never signal an error.
2843 (Finteractive_form): Ignore Qunbound.
2845 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2847 * eval.c (interactive_p): Remove no-longer-used decl.
2849 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2851 * xdisp.c (buffer_shared): Adjust comment.
2852 (buffer_shared_and_changed): New function.
2853 (prepare_menu_bars, redisplay_internal): Use it to
2854 decide whether all windows or frames should be updated.
2855 (window_outdated): New function.
2856 (text_outside_line_unchanged_p, redisplay_window): Use it.
2857 (redisplay_internal): Likewise. Fix indentation.
2859 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2861 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2862 (syms_of_eval): Remove corresponding defsubr.
2863 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2865 2012-11-19 Daniel Colascione <dancol@dancol.org>
2867 * w32fns.c (Fx_file_dialog):
2868 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2869 cygwin_convert_file_name*.
2871 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2872 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2874 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2876 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2878 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2880 * w32select.c: Include w32common.h before w32term.h, so that
2881 windows.h gets included before w32term.h uses some of its
2882 features, see below.
2884 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2886 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2888 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2890 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2892 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2893 (ns_select): Return at once if events are held (Bug#12834).
2895 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2897 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2898 Needed following 2012-10-20 change. (Bug#12902)
2900 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2902 * w32proc.c (waitpid): Remove unused label get_result.
2904 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2906 * makefile.w32-in (SYSWAIT_H): New macro.
2907 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2908 ($(BLD)/sysdep.$(O)): Update dependencies.
2910 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2912 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2913 * callproc.c (relocate_fd): Assume F_DUPFD.
2914 * emacs.c, term.c (O_RDWR): Remove.
2915 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2916 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2917 * nsterm.m: Assume <fcntl.h> exists.
2918 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2919 (create_pty, Fmake_network_process, server_accept_connection)
2920 (wait_reading_process_output, init_process_emacs):
2922 (wait_reading_process_output): Put in a special case for WINDOWSNT
2923 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2924 It's not clear this is needed, but it's a more-conservative change.
2925 (create_process): Assume FD_CLOEXEC.
2926 (create_process, create_pty): Assume O_NOCTTY.
2927 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2928 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2929 Omit if not DOS_NT, since F_GETFL is not defined there.
2930 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2931 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2933 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2934 lack it, since gnulib guarantees this.
2935 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2937 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2939 * w32.c (faccessat): Pretend that directories have the execute bit
2940 set. Emacs expects that, e.g., in files.el:cd-absolute.
2942 * w32proc.c (create_child): Don't clip the PID of the child
2943 process to fit into an Emacs integer, as this is no longer a
2945 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2946 reaping only the process specified by PID argument, if that is
2947 positive. Use PID instead of dead_child to know which process to
2948 reap. Wait for the child to die only if WNOHANG is not in
2950 (sys_select): Don't set dead_child.
2952 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2953 as it is no longer needed.
2955 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2957 (record_child_status_change): Remove the setting of
2958 record_at_most_one_child for the !WNOHANG case.
2960 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2962 Fix problems in ns port found by static checking.
2963 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2964 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2965 not to process group.
2966 (ns_select): Use emacs_write, not write, as that's more robust
2967 in the presence of signals.
2968 (fd_handler:): Check for read errors.
2970 2012-11-16 Glenn Morris <rgm@gnu.org>
2972 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2974 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2976 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2978 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2980 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2981 use the same value of thread handle.
2982 (start_timer_thread): If the timer thread exited (due to error),
2983 clean up by closing the two handles it used. Duplicate the caller
2984 thread's handle here, so it gets duplicated only once, when
2985 launching the timer thread. Set priority of the timer thread, not
2987 (getitimer): Don't duplicate the caller thread's handle here.
2990 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2992 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2995 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2997 Remove no-longer-used pty_max_bytes variable.
2998 * process.c (pty_max_bytes): Remove; unused.
2999 (send_process): Do not set it.
3001 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3003 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3004 Update dependencies.
3006 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3008 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3009 This follows up on the 2012-09-29 patch that removed indirection
3010 for the 'function' field. Reported by Sergey Vinokurov in
3011 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3013 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3015 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3016 different name, as the MS runtime does not have such a function,
3017 and probably never will.) All callers changed. Ignore DIRFD
3018 value if PATH is an absolute file name, to match Posix spec
3019 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3022 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3024 * xdisp.c (echo_area_display, redisplay_internal):
3025 Omit redundant check whether frame_garbaged is set.
3027 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3029 Use faccessat, not access, when checking file permissions (Bug#12632).
3030 This fixes a bug that has been present in Emacs since its creation.
3031 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3032 which must set some sort of record. (Torek's bug report was against
3033 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3034 same common flaw.) See Torek's Usenet posting
3035 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3036 Posted: Fri Apr 8 14:18:56 1983.
3037 * Makefile.in (LIB_EACCESS): New macro.
3039 * callproc.c (init_callproc):
3040 * charset.c (init_charset):
3041 * fileio.c (check_existing, check_executable, check_writable)
3043 * lread.c (openp, load_path_check):
3044 * process.c (allocate_pty):
3046 Use effective UID when checking permissions, not real UID.
3047 * callproc.c (init_callproc):
3048 * charset.c (init_charset):
3049 * lread.c (load_path_check, init_lread):
3050 Test whether directories are accessible, not merely whether they exist.
3051 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3052 * fileio.c (check_existing, check_executable, check_writable)
3054 Use symbolic names instead of integers for the flags, as they're
3056 (check_writable): New arg AMODE. All uses changed.
3057 Set errno on failure.
3058 (Ffile_readable_p): Use faccessat, not stat + open + close.
3059 (Ffile_writable_p): No need to call check_existing + check_writable.
3060 Just call check_writable and then look at errno. This saves a syscall.
3061 dir should never be nil; replace an unnecessary runtime check
3062 with an eassert. When checking the parent directory of a nonexistent
3063 file, check that the directory is searchable as well as writable, as
3064 we can't create files in unsearchable directories.
3065 (file_directory_p): New function, which uses 'stat' on most platforms
3066 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3067 (Ffile_directory_p, Fset_file_times): Use it.
3068 (file_accessible_directory_p): New function, which uses a single
3069 syscall for efficiency.
3070 (Ffile_accessible_directory_p): Use it.
3071 * xrdb.c (file_p): Use file_directory_p.
3072 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3073 * lread.c (openp): When opening a file, use fstat rather than
3074 stat, as that avoids a permissions race. When not opening a file,
3075 use file_directory_p rather than stat.
3076 (dir_warning): First arg is now a usage string, not a format.
3077 Use errno. All uses changed.
3078 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3079 that merely introduced a race.
3080 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3081 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3082 and similarly for the other O_* flags.
3083 * w32.c (sys_faccessat): Rename from sys_access and switch to
3084 faccessat's API. All uses changed.
3085 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3086 (magic_db): Rename from magic_file_p.
3087 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3088 char *, so that we don't have to test for file existence
3089 separately from opening the file for reading. This removes a race
3090 fixes a permission-checking problem, and simplifies the code.
3092 (file_p): Remove; no longer needed.
3094 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3096 Omit glyphs initialization at startup.
3097 * dispnew.c (glyphs_initialized_initially_p): Remove.
3098 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3099 (Fredraw_frame): Move actual code from here...
3100 (redraw_frame): ...to here. Add eassert. Adjust comment.
3101 (Fredraw_display): Use redraw_frame.
3102 * xdisp.c (clear_garbaged_frames): Likewise.
3104 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3106 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3107 passed to pint2str and pint2hrstr to be at most the size of the
3108 frame's decode_mode_spec_buffer. This avoids crashes with very
3109 large values of FIELD_WIDTH argument to decode_mode_spec.
3112 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3114 Fix a race with verify-visited-file-modtime (Bug#12863).
3115 Since at least 1991 Emacs has ignored an mtime difference of no
3116 more than one second, but my guess is that this was to work around
3117 file system bugs that were fixed long ago. Since the race is
3118 causing problems now, let's remove that code.
3119 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3120 whose time stamp is off by no more than a second. Insist that the
3121 file time stamps match exactly.
3123 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3125 * frame.h (struct frame): Convert external_tool_bar member to
3126 1-bit unsigned bitfield.
3127 * termhooks.h (struct terminal): Remove mouse_moved member since
3128 all users are long dead. Adjust comment on mouse_position_hook.
3130 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3132 Simplify by using FOR_EACH_FRAME here and there.
3133 * frame.c (next_frame, prev_frame, other_visible_frames)
3134 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3135 * w32term.c (x_window_to_scroll_bar): Likewise.
3136 * window.c (window_list): Likewise.
3137 * xdisp.c (x_consider_frame_title): Likewise.
3138 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3139 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3140 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3141 * xmenu.c (menubar_id_to_frame): Likewise.
3142 * xselect.c (frame_for_x_selection): Likewise.
3143 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3144 (x_window_to_menu_bar): Likewise.
3145 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3147 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3149 * data.c (Qdefalias_fset_function): Now static.
3151 Another tweak to vectorlike_header change.
3152 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3153 Remove, and replace all uses with ...
3154 (next_in_free_list, set_next_in_free_list):
3155 New functions, which respect C's aliasing rules better.
3157 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3159 * window.c (list4i): Rename from 'quad'. All uses changed.
3160 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3162 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3164 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3165 warning about mixing declarations and code in ISO C90.
3167 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3169 * window.c (Fsplit_window_internal): Set combination limit of
3170 new parent window to t iff Vwindow_combination_limit is t;
3171 fixing a regression introduced with the change from 2012-09-22.
3172 (Fset_window_combination_limit): Fix doc-string.
3174 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3176 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3177 amount when the scroll margins are too large. When scrolling
3178 backwards in the buffer, give up if cannot reach point or the
3179 scroll margin within a reasonable number of screen lines.
3180 Fixes point position in window under scroll-up/down-aggressively when
3181 point is positioned many lines beyond the window top/bottom.
3184 * ralloc.c (relinquish): If real_morecore fails to return memory
3185 to the system, don't crash; instead, leave the last heap
3186 unchanged and return. (Bug#12774)
3188 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3190 * lisp.h (AUTOLOADP): New macro.
3191 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3192 * data.c (Ffset): Remove special ad-advice-info handling.
3193 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3195 (Finteractive_form): Simplify.
3196 (Fquo): Don't insist on having at least 2 arguments.
3197 (Qdefalias_fset_function): New var.
3199 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3201 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
3203 * nsfont.m (Qcondensed, Qexpanded): New variables.
3204 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
3205 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3207 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3209 Fix recently introduced crash on MS-Windows (Bug#12839).
3210 * w32term.h (struct scroll_bar): Use convenient header.
3211 (SCROLL_BAR_VEC_SIZE): Remove.
3212 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3214 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3216 Tweak last vectorlike_header change.
3217 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3218 vectorlike object on the free list. This is introduced to avoid
3219 some (but not all) pointer casting and aliasing problems, see
3220 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3221 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3223 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3225 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3227 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3228 been removed, so remove them here also.
3230 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3232 * doc.c (Fdocumentation): Handle new property
3233 dynamic-docstring-function to replace the old ad-advice-info.
3235 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3237 * fns.c (Qeql, hashtest_eq): Now static.
3239 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3241 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3242 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3243 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
3244 * buffer.c (compare_overlays): Use XLI rather than XHASH.
3246 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
3248 Use same hash function for hashfn_profiler as for hash_string etc.
3249 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3250 * lisp.h (sxhash_combine): New inline function, with the contents
3251 of the old SXHASH_COMBINE.
3252 * profiler.c (hashfn_profiler): Use it, instead of having a
3253 special hash function containing a comparison that always yields 1.
3255 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3257 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)

3259 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3262 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3264 * image.c (xpm_make_color_table_h): Fix compiler error because

3269 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3271 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3273 Use ad-hoc comparison function for the profiler's hash-tables.
3274 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3275 (make_log): Use them.
3276 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3277 call Fequal any more.

3286 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3287 (hash_lookup, hash_remove_from_table): Move assertion checking of
3288 hashfn result here. Check hash-equality before calling cmpfn.

3298 2012-11-08 Eli Zaretskii <eliz@gnu.org>
3300 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3301 value of w32-scroll-lock-modifier is neither nil nor one of the
3302 known key modifiers. (Bug#12806)
3304 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3306 Shrink struct vectorlike_header to the only size field.
3307 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3309 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3310 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3311 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3312 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3313 information from the vector header. Adjust comment.

3334 (allocate_vectorlike): Likewise.
3335 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3336 Add easserts. Adjust XSETPVECTYPESIZE usage.
3337 (allocate_buffer): Use BUFFER_PVEC_INIT.
3338 (live_vector_p): Adjust to match large vector.
3339 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3340 * buffer.h (struct buffer): Add next member.
3341 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3343 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

3351 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3353 * keyboard.c (event_to_kboard): Do not dereference
3354 frame_or_window field of SELECTION_REQUEST_EVENT
3355 and SELECTION_CLEAR_EVENT events (Bug#12814).
3356 * xterm.h (struct selection_input_event): Adjust comment.
3358 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3360 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3361 such as Scroll Lock, if the respective keys are treated as
3362 function keys, not as modifiers. This avoids destroying non-ASCII
3363 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3365 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3367 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3369 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3371 Restore some duplicate definitions (Bug#12814).
3372 This undoes part of the 2012-11-03 changes. Some people build
3373 with plain -g rather than with -g3, and they need the duplicate
3374 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3375 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3376 Define as macros, as well as as enums or as constants.
3378 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3380 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3381 to keypad keys (Bug#12816).
3383 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3385 Minor adjustments of recently-changed frame functions.
3386 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3387 known to be a frame (we're in the FRAMEP branch).
3388 * lisp.h (Qframep): Remove decl. frame.h declares this.
3389 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3390 since they're meant for Lisp fixnum values.
3392 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3394 * window.c (Fwindow_combination_limit): Revert to the only
3395 required argument and adjust docstring as suggested in
3396 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3397 by Martin Rudalics <rudalics@gmx.at>.
3399 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3401 Widely used frame validity and checking functions.
3402 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3403 * frame.c (decode_live_frame, decode_any_frame): New functions.
3404 (delete_frame, Fredirect_frame_focus, Fframe_parameters)

3413 (frame_buffer_list, frame_buffer_predicate): Remove.
3414 * lisp.h (frame_buffer_predicate): Remove prototype.
3415 * buffer.c (Fother_buffer): Use decode_any_frame.
3416 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3417 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3418 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3419 (Fclose_font, Ffont_info): Use decode_live_frame.
3420 * fontset.c (check_fontset_name): Likewise.
3421 * terminal.c (Fframe_terminal): Likewise.
3422 * w32fns.c (check_x_frame): Likewise.
3423 * window.c (Fminibuffer_window, Fwindow_at)
3424 (Fcurrent_window_configuration): Likewise.
3425 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3426 Likewise. Allow zero number of arguments. Adjust docstring.
3427 * dispnew.c (Fredraw_frame): Likewise.
3428 * xfaces.c (frame_or_selected_frame): Remove.
3429 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3430 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3431 (Fframe_face_alist): Use decode_live_frame.
3432 * xfns.c (check_x_frame): Likewise.
3434 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3436 * window.c (quad): New function.
3437 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3438 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3439 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3440 (Fwindow_line_height): Use it.
3441 (Fwindow_fringes): Use list3.
3442 (Fwindow_scroll_bars): Use list4.
3443 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3444 (Fwindow_combination_limit): Allow zero number of arguments.
3446 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3448 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3450 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3451 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3452 file descriptor 2 for standard error. (Bug#12805)
3454 2012-11-05 Chong Yidong <cyd@gnu.org>
3456 * process.c (wait_reading_process_output): Revert previous change.
3458 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3460 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3461 This removes code that has been obsolete since around 1990.
3462 * callproc.c (Fcall_process):
3464 * process.c (create_process):
3465 * term.c (dissociate_if_controlling_tty):
3466 Assume setsid exists.
3467 * callproc.c (child_setup): Assume setpgid exists and behaves as
3468 per POSIX.1-1988 or later.
3469 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3470 * emacs.c (shut_down_emacs):
3471 * sysdep.c (sys_suspend, init_foreground_group):
3472 Assume getpgrp behaves as per POSIX.1-1998 or later.
3473 * msdos.c (setpgrp): Remove.
3474 (tcgetpgrp, setpgid, setsid): New functions.
3475 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3476 * term.c (no_controlling_tty): Remove; unused.
3477 * w32proc.c (setpgrp): Remove.
3478 (setsid, tcgetpgrp): New functions.
3480 Simplify by assuming __fpending.
3481 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3482 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3483 Do not assume that __fpending's result fits in int.
3485 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3487 Remove EMACS_OUTQSIZE+sleep hack.
3488 * dispnew.c (update_frame_1): Remove hack for terminals slower
3489 than 2400 bps, which throttled Emacs by having it sleep.
3490 This code hasn't worked since at least 2007, when the multi-tty stuff
3491 was added, and anyway those old terminals are long dead.
3492 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3493 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3495 Fix data-loss with --version (Bug#9574).
3496 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3497 as we can't assume that emacs_strerror is initialized, and strerror
3498 is good enough here.
3499 (main): Invoke atexit earlier, to catch earlier instances of
3500 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3502 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3504 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3505 (keyDown): Remap keypad keys to X11 virtual key codes.
3507 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3509 Fix data-loss with --batch (Bug#9574).
3510 * emacs.c: Include <close-stream.h>.
3511 (close_output_streams): New function.
3512 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3513 and handles errors appropriately.
3514 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3517 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3518 The symptom is a diagnostic "GLib-WARNING **: In call to
3519 g_spawn_sync(), exit status of a child process was requested but
3520 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3521 waitpid(), so exit status can't be returned." The diagnostic
3522 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3523 The real bug is a race condition between Emacs and glib: Emacs
3524 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3525 so that glib can't find it. Work around the bug by invoking
3526 waitpid only on subprocesses that Emacs itself creates.
3527 * process.c (create_process, record_child_status_change):
3528 Don't use special value -1 in pid field, as the caller now must
3529 know the pid rather than having the callee infer it.
3530 The inference was sometimes incorrect anyway, due to another race.
3531 (create_process): Set new 'alive' member if child is created.
3532 (process_status_retrieved): New function.
3533 (record_child_status_change): Use it.
3534 Accept negative 1st argument, which means to wait for the
3535 processes that Emacs already knows about. Move special-case code
3536 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3537 processes that have already been waited for, by testing and
3538 clearing new 'alive' member.
3539 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3540 now does this internally.
3541 (handle_child_signal): Let record_child_status_change do all
3542 the work, since we do not want to reap all exited child processes,
3543 only the child processes that Emacs itself created.
3544 * process.h (Lisp_Process): New boolean member 'alive'.
3546 Omit duplicate definitions no longer needed with gcc -g3.
3547 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3548 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3549 Define only as macros. There's no longer any need to also define
3550 these symbols as enums or as constants, since we now assume
3551 gcc -g3 when debugging.
3553 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3555 * lisp.mk: Adjust comments to the fact that term/internal is now
3556 loaded from loadup.el.
3558 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3559 (msdos_fatal_signal): New function.
3560 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3563 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3564 for GCC versions before 4.
3565 (emacs_raise): Define to call msdos_fatal_signal.
3567 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3568 iterator when starting in the middle of a display or overlay
3571 2012-11-03 Chong Yidong <cyd@gnu.org>
3573 * process.c (wait_reading_process_output): Clean up the last
3576 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3578 * process.c (wait_reading_process_output): Avoid a race condition
3579 with SIGIO delivery (Bug#11536).
3581 2012-11-03 Chong Yidong <cyd@gnu.org>
3583 * buffer.c (cursor_type): Untabify docstring.
3585 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3587 * frame.h (struct frame): Drop can_have_scroll_bars member
3588 which is meaningless for a long time. Adjust comments.
3589 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3590 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3592 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3594 * window.c (decode_next_window_args): Update window arg after
3595 calling decode_live_window and so fix crash reported at
3596 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3597 by Juanma Barranquero <lekktu@gmail.com>.
3598 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3599 * font.c (Ffont_at): Likewise.
3601 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3603 * widget.c (resize_cb): New function.
3604 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3605 (EmacsFrameResize): Check if all is up to date before changing frame
3608 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3610 Implement backtrace output for fatal errors on MS-Windows.
3611 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3612 (BACKTRACE_LIMIT_MAX): New macro.
3613 (w32_backtrace): New function.
3614 (emacs_abort): Use w32_backtrace when the user chooses not to
3615 attach a debugger. Update the text of the abort dialog.
3617 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3619 Window-related stuff cleanup here and there.
3620 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3621 Use decode_any_window.
3622 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3623 * xdisp.c (Fformat_mode_line): Likewise.
3624 * font.c (Ffont_at): Use decode_live_window.
3625 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.

3629 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3630 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3633 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3635 Remove pad from struct input_event.
3636 * termhooks.h (struct input_event): Remove padding field.
3638 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3639 member is never cons for a long time. Adjust comment.
3640 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3641 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3642 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3643 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3645 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3647 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3649 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3651 Fix crash when using Emacs as commit editor for git (Bug#12697).
3652 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3653 and it is configured in conf_post.h.
3654 (Fcall_process): Don't invoke both setsid and setpgid; the former
3655 is enough, if it exists.
3656 * callproc.c (Fcall_process, child_setup):
3657 * process.c (create_process): Use setpgid.
3658 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3660 * dispnew.c (init_display): Initialize the foreground group
3661 if we are running a tty display.
3662 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3663 * lisp.h (init_foreground_group): New decl.
3664 * sysdep.c (inherited_pgroup): New static var.
3665 (init_foreground_group, tcsetpgrp_without_stopping)
3666 (narrow_foreground_group, widen_foreground_group): New functions.
3667 (init_sys_modes): Narrow foreground group.
3668 (reset_sys_modes): Widen foreground group.

3674 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3676 * minibuf.c (read_minibuf): Restore current buffer since
3677 choose_minibuf_frame calling Fset_frame_selected_window may
3678 change it (Bug#12766).
3680 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3682 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).

3687 displaying the current buffer, signal an error.
3689 2012-10-29 Daniel Colascione <dancol@dancol.org>
3691 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3692 In preparation for fixing bug#12739, move these functions from
3695 * coding.h, coding.c: ... to here, and compile them only when
3696 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3697 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3699 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3701 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3702 (timer_loop, getitimer, setitimer): Use it instead of
3703 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3705 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3708 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3710 * nsterm.m (NO_APPDEFINED_DATA): New define.
3711 (last_appdefined_event_data): New variable
3712 (last_appdefined_event): Remove.
3713 (ns_select): Initialize t from last_appdefined_event_data instead
3714 of [last_appdefined_event data1].
3715 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3716 remove last_appdefined_event (Bug#12698).
3718 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3720 * frame.c (x_set_font): Catch internal error.
3722 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3724 Avoid overflow in w32 implementation of interval timers.
3725 When possible, for ITIMER_PROF count only times the main thread
3727 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3728 'volatile ULONGLONG' types. All the other data which was
3729 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3730 (GetThreadTimes_Proc): New typedef.
3731 (w32_get_timer_time): New function, returns a suitable time value
3733 (timer_loop): Enter critical section when accessing ULONGLONG
3734 values of the itimer_data struct, as these accesses are no longer
3735 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3736 Remove unused variable.
3737 (init_timers): Initialize s_pfn_Get_Thread_Times.
3738 (start_timer_thread): Don't assign itimer->caller_thread here.
3739 (getitimer): Assign itimer->caller_thread here.
3740 (setitimer): Always call getitimer to get the value of ticks_now.

3745 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3746 mouse movement events if the menu bar is active. This avoids
3747 producing a busy "hour-glass" cursor by Windows if the mouse
3748 pointer is positioned over a tooltip shown for some menu item.
3750 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3752 Don't assume process IDs fit in int.
3753 * emacs.c (shut_down_emacs) [!DOS_NT]:
3754 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3755 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3756 Use pid_t, not int, to store process IDs, as 'int'
3757 is not wide enough on a few platforms (e.g., AIX and IRIX).
3759 2012-10-23 Kenichi Handa <handa@gnu.org>
3761 The following change is to make face-font-rescale-alist work
3762 correctly for non-ASCII fonts.

3765 (font_open_for_lface): Handle Vface_font_rescale_alist.
3767 2012-10-23 Chong Yidong <cyd@gnu.org>
3769 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.

3782 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3784 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>

3787 * frame.c (Fmouse_position, Fmouse_pixel_position):
3788 * xdisp.c (produce_stretch_glyph):
3789 Declare local vars only when they're needed.
3790 This is clearer and avoids a warning on OpenBSD about unused vars.

3792 This is safer, and avoids OpenBSD warnings about unused vars.
3793 * keyboard.c (record_menu_key): Remove unnecessary decl.
3794 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3795 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3796 as our definition clashes with OpenBSD's.
3797 * xfaces.c (load_face_colors, check_lface_attrs)
3798 (get_lface_attributes_no_remap, get_lface_attributes)
3799 (lface_fully_specified_p, x_supports_face_attributes_p)
3800 (tty_supports_face_attributes_p, face_fontset, realize_face)
3801 (realize_x_face, realize_tty_face):
3802 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3803 merely Lisp_Object *. This is more informative and avoids
3804 a warning on OpenBSD about accessing beyond an object's size.
3806 2012-10-20 Chong Yidong <cyd@gnu.org>
3808 * lread.c (Fload): Doc fix (Bug#12592).

3834 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3835 (staticpro): If we run out of staticpro slots, die with an
3836 informative error instead of just calling emacs_abort.
3838 2012-10-18 Martin Rudalics <rudalics@gmx.at>
3840 Fix two flaws reported by Dmitry Antipov.

4098 the same pointer-to-int (now pointer-to-boolean) &input_pending,

4100 input_pending. All callers changed.
4101 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4102 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

4149 'is_tooltip_frame', to avoid confusion with its global namesake.
4151 2012-10-08 Daniel Colascione <dancol@dancol.org>
4153 * xdisp.c (start_hourglass): Call w32_note_current_window when
4154 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4155 build that caused Emacs to display the hourglass cursor forever.
4157 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4158 which is broken under remote desktop, calculate the number of
4159 colors available for a display based on the display's number of

4174 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4175 Update dependencies.
4177 * w32term.c: Remove leftover declaration of keyboard_codepage.
4179 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4181 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4182 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4183 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4184 (GLOBAL_SOURCES): Add cygw32.c.
4185 ($(BLD)/unexw32.$(O)):
4187 ($(BLD)/w32console.$(O)):
4188 ($(BLD)/w32fns.$(O)):
4189 ($(BLD)/w32heap.$(O)):
4190 ($(BLD)/w32menu.$(O)):
4191 ($(BLD)/w32proc.$(O)): Add w32common.h.
4193 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4195 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4197 2012-10-08 Daniel Colascione <dancol@dancol.org>
4199 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4200 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4201 accidental message numbering hole. Change other messages to
4204 * w32select.h (HAVE_W32SELECT): Remove.
4206 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4207 w32common.h instead of w32heap.h.
4209 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4210 (get_allocation_unit, get_processor_type, get_w32_major_version)
4211 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4212 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4213 (OS_NT, os_subtype, cache_system_info): Move declarations to
4216 * w32heap.c: Include w32common.h.
4217 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4218 (w32_minor_version, w32_build_number, w32_subtype):
4219 Remove duplicate definitions.
4221 * w32fns.c: Include w32common.h; include w32heap.h only in
4224 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4225 Use `report_file_error' instead of `error' in order to better
4226 inform users of what went wrong. Increase NTGUI_UNICODE file
4227 dialog box file name length to 32k, the maximum allowed by the NT
4230 * w32common.h: New file.
4231 (ROUND_UP, ROUND_DOWN, get_page_size)
4232 (get_allocation_unit, get_processor_type, get_w32_major_version)
4233 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4234 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4235 (OS_NT, os_subtype, cache_system_info): Move here.
4237 * unexw32.c, unexcw.c: Include w32common.h.
4239 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4240 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4241 to call syms_of_w32select.
4243 * cygw32.h: Remove obsolete EXFUN declarations.
4245 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4247 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4248 of w32inevt.o from SOME_MACHINE_OBJECTS.
4250 2012-10-08 Daniel Colascione <dancol@dancol.org>
4252 * image.c: Permanent fix for JPEG compilation issue --- limit
4253 jpeglib `boolean' redefinition to Cygwin builds.
4255 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4257 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4259 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4262 2012-10-08 Daniel Colascione <dancol@dancol.org>
4264 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4265 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4266 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4267 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4268 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4269 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4270 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4271 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4272 now a supported configuration.
4274 * Makefile.in: consolidate image variables into LIBIMAGE; add
4275 W32_OBJ and W32_LIBS. Compile new files.
4278 (_DebPrint) declare tracing facility for W32 debugging. We need
4279 to unify tracing later.
4281 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4282 unconditional use of W32 Unicode functions. Cygwin runs only on
4283 100% Unicode operating systems.
4285 * cygw32.c: New file. Define Cygwin-specific facilities.
4286 (Fcygwin_convert_path_to_windows)
4287 (Fcygwin_convert_path_from_windows): New user functions for
4288 accessing Cygwin path-munging routines.
4290 * cygw32.h: New file.
4291 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4292 UTF-16LE strings temporarily inside non-Lisp-visible string
4295 (w32_strerror): Just what it says on the tin.
4297 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4298 also run for Cygwin; both systems have the same problem with using
4299 GUI facilities in a forked child. Also call syms_of_cygw32,
4300 syms_of_w32select in correct places.
4302 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4303 needs fork-then-exec for daemon launching.
4305 * font.h: Include frame.h.
4307 * image.c: Use the image library cache machinery only when we're
4308 compiling for native WINDOWSNT; Cygwin can use shared libraries
4309 like any other Unixlike system.
4311 * keyboard.c: Clarify a comment regarding the input loop.
4313 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4314 functions directly instead of trying to detect at runtime that our
4315 host operating system supports them. We make this change for two
4316 reasons: Cygwin lacks support for the multibyte character
4317 conversion functions used by the legacy menu code, and Cygwin
4318 never needs to rely on non-Unicode APIs.
4320 * unexw32.c (hinst): Declare extern.
4322 * w32.c: Change header order;
4323 (w32_strerror): Move to w32fns.c because we need it for
4324 non-WINDOWSNT builds.
4326 * w32.h: Add #error macro to make sure we don't include w32.h for
4327 Cygwin builds. Remove w32select declarations.
4329 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4330 w32fns.c. w32console.c is WINDOWSNT-only.
4332 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4333 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4335 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4336 (w32_major_version, w32_minor_version, w32_build_number)
4337 (os_subtype, sound_type): Define here
4338 (w32_defined_color): Make color parameter const for consistency
4339 with other _defined_color functions.
4340 (w32_createwindow): Unconditionally call w32_init_class instead of
4341 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4342 through the code is complex and unnecessary because class
4343 registration is practically free.
4344 (w32_name_of_message): New EMACSDEBUG-only function.
4345 (Fset_message_beep): Move here
4346 (Fx_open_connection): Require that the display name for Windows be
4347 "w32" for consistency, emacsclient disambiguation, and maybe, one
4348 day, multi-window-system support.
4349 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4350 Cygwin files for W32 GUI facilities, since these clearly don't
4351 expect Cygwin names.
4352 (_DebPrint): Define.
4353 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4354 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4355 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4356 (w32_last_error): Remove.
4358 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4360 * w32heap.c (syspage_mask): Declare here.
4361 (cache_system_info): Remove.
4363 * w32inevt.c (faked_key): Define globally, not statically.
4364 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4365 (w32_console_toggle_lock_key): Move to w32fns.c.
4367 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4369 * w32proc.c (_DebPrint): Move to w32fns.c.
4370 * w32select.c: Include string.h, stdio.h for Cygwin.
4371 * w32select.h: New File.
4373 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4375 (w32_message_fd): New variable. Under Cygwin, holds the file
4376 descriptor the system used to tell us about pending thread
4379 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4380 that prevented compilation under non-WINDOWSNT systems.
4382 (w32_initialize): Open /dev/windows and assign it to
4383 w32_message_fd. Provide w32 feature.
4385 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4386 (WM_EMACS_INPUT_READY): add.
4387 (prepend_msg, w32_message_fd): Declare globally.
4390 (keyboard_handle): Use only when WINDOWSNT.
4391 (notify_msg_ready): New function. Posts a message to the main
4392 thread's message queue under CYGWIN, which wakes up the main
4393 thread from select(2) by making the /dev/windows file descriptor
4394 ready. Under WINDOWSNT, it sets an event the same way the old
4397 (post, prepend_msg): Actually call notify_msg_ready instead of
4398 setting the input event directly.
4400 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4402 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4403 but it still has blocs in it, don't return it to the system,
4404 instead of aborting. (Bug#12402)
4406 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4408 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4410 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4411 MAC_OS_X_VERSION_10_6.
4412 (syms_of_nsterm): Remove comment about Panther and above for
4414 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4415 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4416 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4418 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4419 MAC_OS_X_VERSION_10_4.
4421 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4422 MAC_OS_X_VERSION_10_2.
4424 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4426 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4427 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4429 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4430 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4431 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4432 Remove ns_in_resize check.
4433 (ns_clear_frame_area): Remove resize handle code.
4435 * nsfns.m (ns_in_resize): Remove.
4436 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4437 Remove ns_in_resize check.
4439 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4441 Improve sys_siglist detection.
4442 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4443 defined as a macro, as is done in Solaris.
4444 (sys_siglist_entries): New macro.
4445 (save_strsignal): Use it.
4446 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4447 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4449 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4451 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4452 fullscreen/Fullscreen.
4454 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4455 tobar_height is new.
4457 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4458 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4459 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4460 (windowDidResize:): Check for correct window if old style fullscreen.
4461 Capitalize word in comment. Remove incorrect comment.
4462 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4463 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4464 error in drawing background.
4465 (toggleFullScreen:): Remove comment. Rearrange calls.
4466 Set toolbar values to zero, save old height in tobar_height.
4467 Restore tool bar height when leaving fullscreen.
4468 (canBecomeMainWindow): New function.
4470 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4472 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4474 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4476 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4478 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4479 that time stamps of directories could also be changed.
4480 Don't request the too broad GENERIC_WRITE, only the more restrictive
4481 FILE_WRITE_ATTRIBUTES access rights.
4483 * fileio.c (Fset_file_times): Special-case ignoring errors for
4484 directories only on MSDOS, not on MS-Windows.
4486 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4488 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4490 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4492 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4493 see whether CreateFile failed.
4495 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4497 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4498 to avoid similar races.
4499 * keyboard.c (pending_signals): Now bool, not int.
4501 Port timers to OpenBSD, plus check for timer failures.
4502 OpenBSD problem reported by Han Boetes.
4503 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4505 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4506 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4507 like OpenBSD, which has timer_settime but does not declare it.
4508 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4509 whether to use itimerspec-related primitives. All uses of
4510 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4512 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4514 * profiler.c (handle_profiler_signal): Fix a malloc race
4515 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4517 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4519 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4521 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4523 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4524 consistent with the change in return value of 'safe_strsignal'.
4526 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4528 Prefer plain 'static' to 'static inline' (Bug#12541).
4529 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4530 (bidi_set_sor_type, bidi_push_embedding_level)
4531 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4532 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4533 (bidi_cache_search, bidi_cache_ensure_space)
4534 (bidi_cache_iterator_state, bidi_cache_find)
4535 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4536 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4537 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4538 Now 'static', not 'static inline'.
4540 Count overruns when profiling; change units to ns.
4541 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4542 Give extra weight to samples after overruns, to attempt to count
4543 the time more accurately.
4544 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4545 the underlying primitives nominally do ns.
4546 (Fprofiler_cpu_start): Document the change. Mention that
4547 the sampling intervals are only approximate.
4549 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4551 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4553 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4554 case for the special 0 coding-system.
4556 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4557 (Fmake_overlay): Remove redundant tests.
4558 (fix_start_end_in_overlays): Remove redundant recentering.
4560 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4562 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4563 Update dependencies.
4565 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4567 Fix a malloc race condition involving strsignal.
4568 A signal can arrive in the middle of a malloc, and Emacs's signal
4569 handler can invoke strsignal, which can invoke malloc, which is
4570 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4571 Fix it by altering the signal handler so that it does not invoke
4573 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4574 * process.c (status_message): Use const pointer, in case strsignal
4575 is #defined to safe_strsignal.
4576 * sysdep.c (sys_siglist, init_signals): Always define and
4577 initialize a substitute sys_siglist if the system does not define
4578 one, even if HAVE_STRSIGNAL.
4579 (safe_strsignal): Rename from strsignal. Always define,
4580 using sys_siglist. Return a const pointer.
4581 * syssignal.h (safe_strsignal): New decl.
4582 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4584 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4586 * w32proc.c (timer_loop): Fix code that waits for timer
4587 expiration, to avoid high CPU usage.
4589 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4591 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4592 (sweep_weak_table): Remove redundant prototypes.
4594 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4596 * emacs.c: Move the inclusion of TERM_HEADER after including
4597 windows.h on WINDOWSNT. This avoids compilation problems with
4600 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4602 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4603 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4604 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4605 as the previous version used 'void *'.
4607 * ralloc.c (ROUNDUP): Fix last change.
4608 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4611 * w32proc.c <disable_itimers>: New static flag.
4612 (init_timers): Initialize it to zero, after creating the critical
4613 sections used by the timer threads.
4614 (term_timers): Set to 1 before deleting the critical sections.
4615 (getitimer, setitimer): If disable_itimers is non-zero, return an
4616 error indication without doing anything. Reported by Fabrice
4617 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4618 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4620 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4623 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4624 term_ntproc after all the other bookkeeping, to get timers working
4625 as long as possible.
4627 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4629 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4630 Suggested by Juri Linkov in
4631 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4633 Prefer plain 'static' to 'static inline' (Bug#12541).
4634 With static functions, modern compilers inline pretty well by
4635 themselves; advice from programmers often hurts as much as it helps.
4636 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4637 this change shrinks the text size of the Emacs executable by 1.1%
4638 without affecting CPU significantly in my benchmark.
4639 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
4640 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

5012 Since this stuff is now private to charset.c, there's no need for
5013 a public macro and no need to inline by hand.

5085 (sigaction): Rewrite to call sys_signal instead of duplicating its
5087 (sys_kill): Improve commentary.
5089 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5090 consistency with a signature of a signal handler. All callers
5092 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5093 install term_ntproc as a signal handler for SIGABRT, as that
5094 should be done by the dumped Emacs.
5096 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5098 * w32select.c (term_w32select): Protect against repeated
5099 invocation by setting clipboard_owner to NULL after calling
5102 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5103 and term_ntproc to their modified signatures.
5105 * character.c (char_string, string_char): Remove calls to
5106 MAYBE_UNIFY_CHAR. See the discussion starting at
5107 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
5110 2012-09-25 Chong Yidong <cyd@gnu.org>
5112 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
5114 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5116 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5117 when encountering an unknown bytecode.
5119 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5121 image.c, indent.c: Use bool for booleans.
5122 * dispextern.h (struct image_type): Members valid_p, load, init
5123 now return bool, not int. All uses changed.
5124 * image.c: Omit unnecessary static decls.
5125 (x_create_bitmap_mask, x_build_heuristic_mask):
5126 Return void, not int, since callers don't care about the return value.
5127 (x_create_bitmap_mask, define_image_type, valid_image_p)

5155 Use bool for booleans.
5157 2012-09-24 Chong Yidong <cyd@gnu.org>
5159 * chartab.c (Fset_char_table_default): Obsolete function removed.
5161 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5163 Move pid_t related decls out of lisp.h.
5164 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5165 (interruptible_wait_for_termination):
5166 Move these decls from lisp.h to syswait.h, since they use pid_t.
5167 Needed on FreeBSD; see Herbert J. Skuhra in
5168 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5169 * callproc.c: Include syswait.h.

5185 * gtkutil.c, w32term.c, xterm.c (x_wm_set_size_hint):
5186 * nsmenu.m (ns_update_menubar):
5187 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
5188 * xfns.c (Fx_show_tip) [USE_GTK]:
5189 Use bool for boolean.
5190 * gtkutil.c (xg_update_frame_menubar):
5191 * xmenu.c (update_frame_menubar):
5192 Return void, not int, since caller ignores return value.

5196 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5198 * makefile.w32-in (BLOCKINPUT_H): Remove.

5215 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5217 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5218 fatal_error_backtrace.
5220 * w32proc.c (sys_kill): Undo last change: don't do anything when
5221 invoked to deliver SIGABRT to our own process. This is now
5222 handled by emacs_raise.
5224 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5226 * w32term.c (w32_read_socket): Remove leftover reference to
5227 interrupt_input_pending.
5229 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5231 Do not use SA_NODEFER.
5232 Problem reported by Dani Moncayo in
5233 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5235 * sysdep.c (emacs_abort): Do not reset signal handler.
5236 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5237 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5238 wanted even on POSIXish hosts, and it doesn't work on Windows.
5240 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5242 * xterm.c (x_term_init): Call fixup_locale before and after calling
5243 gtk_init (Bug#12392).
5245 2012-09-23 Chong Yidong <cyd@gnu.org>
5247 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5248 Vdynamic_library_alist.
5250 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5251 (Fgnutls_available_p): Caller changed.
5253 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5254 (Flibxml_parse_xml_region): Likewise.
5256 * dispextern.h (struct image_type): Remove arg from init function.
5258 * image.c (Finit_image_library, lookup_image_type)
5259 (define_image_type): Remove now-unneeded second arg.
5260 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5261 (init_tiff_functions, init_gif_functions, init_svg_functions):
5262 Arglist and w32_delayed_load calling convention changed.
5263 (gs_type): Remove init_gs_functions; there is no such function.
5264 (valid_image_p, make_image): Fix caller to lookup_image_type.
5266 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5268 Simplify and avoid signal-handling races (Bug#12471).
5270 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5271 Avoid recursive loop if there's a fatal error in the function itself.
5272 * atimer.c (pending_atimers):
5273 * blockinput.h: Don't include "atimer.h"; no longer needed.
5274 (interrupt_input_pending): Remove. All uses removed.
5275 pending_signals now counts both atimers and ordinary interrupts.
5276 This is less racy than having three separate pending-signal flags.
5277 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5279 Rename from their upper-case counterparts BLOCK_INPUT,
5280 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5281 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5282 This makes it easier to access volatile variables more accurately.
5283 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5284 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5285 that's more reliable if the code is buggy and sets
5286 interrupt_input_blocked to a negative value. All uses changed.
5287 * atimer.c (deliver_alarm_signal):
5288 Remove. No need to deliver this to the parent; any thread can
5289 handle this signal now. All uses replaced by underlying handler.
5290 * atimer.c (turn_on_atimers):
5291 * dispnew.c (handle_window_change_signal):
5292 * emacs.c (handle_danger_signal):
5293 * keyboard.c (kbd_buffer_get_event):
5294 Don't reestablish signal handler; not needed with sigaction.
5295 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5297 Rework to avoid unnecessary accesses to volatile variables.
5298 (UNBLOCK_INPUT_TO): Now a function.
5299 (totally_unblock_input, unblock_input): New decls.
5300 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5301 (init_data): Remove. Necessary stuff now done in init_signal.
5302 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5303 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5304 (fatal_error_code): Remove; no longer needed.
5305 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5306 it doesn't always backtrace. All uses changed. No need to reset
5307 signal to default, since sigaction and/or die does that for us now.
5308 Use emacs_raise (FOO), not kill (getpid (), FOO).
5309 (main): Check more-accurately whether we're dumping.
5310 Move fatal-error setup to sysdep.c
5311 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5312 * gtkutil.c (xg_get_file_name, xg_get_font):
5313 Remove no-longer-needed signal-mask manipulation.
5314 * keyboard.c, process.c (POLL_FOR_INPUT):
5315 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5316 * keyboard.c (read_avail_input): Remove.
5317 All uses replaced by gobble_input.
5318 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5319 (kbd_buffer_store_event_hold, gobble_input):
5320 (record_asynch_buffer_change) [USABLE_SIGIO]:
5321 (store_user_signal_events):
5322 No need to mess with signal mask.
5323 (gobble_input): If blocking input and there are terminals, simply
5324 set pending_signals to 1 and return. All hooks changed to not
5325 worry about whether input is blocked.
5326 (process_pending_signals): Clear pending_signals before processing
5327 them, in case a signal comes in while we're processing.
5328 By convention callers now test pending_signals before calling us.
5329 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5330 New functions, to support changes to blockinput.h.
5331 (handle_input_available_signal): Now extern.
5332 (reinvoke_input_signal): Remove. All uses replaced by
5334 (quit_count): Now volatile, since a signal handler uses it.
5335 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5336 All callers changed. Block SIGINT only if not already blocked.
5337 Clear sigmask reliably, even if Fsignal returns, which it can.
5338 Omit unnecessary accesses to volatile var.
5339 (quit_throw_to_read_char): No need to restore sigmask.
5340 * keyboard.c (gobble_input, handle_user_signal):
5341 * process.c (wait_reading_process_output):
5342 Call signal-handling code rather than killing ourselves.
5343 * lisp.h: Include <float.h>, for...
5344 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5345 (pending_signals): Now volatile.
5346 (syms_of_data): Now const if IEEE floating point.
5347 (handle_input_available_signal) [USABLE_SIGIO]:
5348 (terminate_due_to_signal, record_child_status_change): New decls.
5349 * process.c (create_process): Avoid disaster if memory is exhausted
5350 while we're processing a vfork, by tightening the critical section
5352 (send_process_frame, process_sent_to, handle_pipe_signal)
5353 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5355 (send_process): No need for setjmp/longjmp any more, since the
5356 SIGPIPE stuff is now gone. Instead, report an error if errno
5358 (record_child_status_change): Now extern. PID and W are now args.
5359 Return void, not bool. All callers changed.
5360 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5361 Remove. All uses removed. This bug should be fixed now in a
5363 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5364 and record the child status change directly. This avoids the
5365 need to futz with the signal mask.
5366 (process_fatal_action): Move here from emacs.c.
5367 (emacs_sigaction_flags): New function, containing
5368 much of what used to be in emacs_sigaction_init.
5369 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5370 caught by emacs, to make races less likely.
5371 (deliver_process_signal): Rename from handle_on_main_thread.
5373 (BACKTRACE_LIMIT_MAX): Now at top level.
5374 (thread_backtrace_buffer, threadback_backtrace_pointers):
5376 (deliver_thread_signal, deliver_fatal_thread_signal):
5377 New functions, for more-accurate delivery of thread-specific signals.
5378 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5379 (deliver_arith_signal): Handle in this thread, not
5380 in the main thread, since it's triggered by this thread.
5381 (maybe_fatal_sig): New function.
5382 (init_signals): New arg DUMPING so that we can be more accurate
5383 about whether we're dumping. Caller changed.
5384 Treat thread-specific signals differently from process-general signals.
5385 Block all signals while handling fatal error; that's safer.
5386 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5388 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5389 Ignore SIGPIPE unless batch.
5390 (emacs_backtrace): Output backtrace for the appropriate thread,
5391 which is not necessarily the main thread.
5392 * syssignal.h: Include <stdbool.h>.
5393 (emacs_raise): New macro.
5394 * xterm.c (x_connection_signal): Remove; no longer needed
5395 now that we use sigaction.
5396 (x_connection_closed): No need to mess with sigmask now.
5397 (x_initialize): No need to reset SIGPIPE handler here, since
5398 init_signals does this for us now.
5400 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5402 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5403 background rect may be larger (Bug#12245).
5405 2012-09-23 Chong Yidong <cyd@gnu.org>
5407 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5409 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5411 * .gdbinit: Just stop at fatal_error_backtrace.
5412 See Stefan Monnier's request in
5413 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5414 Remove no-longer-used query of system type.
5416 2012-09-22 Chong Yidong <cyd@gnu.org>
5418 * search.c (Freplace_match): Doc fix (Bug#12325).
5420 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5422 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5423 (Fline_end_position): Doc fix.
5425 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5427 2012-09-22 Chong Yidong <cyd@gnu.org>
5429 * dispextern.h (struct image_type): Add new slot, storing a type
5430 initialization function.
5432 * image.c (define_image_type): Call the image initializer function
5433 if it is defined. Arguments and return value changed.
5434 (valid_image_p, make_image): Callers changed.
5435 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5436 (gif_type, imagemagick_type, svg_type, gs_type):
5437 Add initialization functions.
5438 (Finit_image_library): Call lookup_image_type.
5439 (CHECK_LIB_AVAILABLE): Macro deleted.
5440 (lookup_image_type): Call define_image_type here, rather than via
5441 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5442 (syms_of_image): Move define_image_type calls for xbm_type and
5443 pbm_type to lookup_image_type.
5445 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5447 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5448 'idle_timers' from here ...
5449 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5450 lists, to avoid infloops when the timer does something stupid,
5451 like reinvoke itself with the same or smaller time-out.
5454 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5456 * window.c (Fsplit_window_internal): Handle only Qt value of
5457 Vwindow_combination_limit separately.
5458 (Qtemp_buffer_resize): New symbol.
5459 (Vwindow_combination_limit): New default value.
5462 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5464 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5465 the new overlay string. (Bug#10159)
5467 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5469 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5470 or that fprintf is async-signal-safe. POSIX doesn't require
5473 2012-09-22 Chong Yidong <cyd@gnu.org>
5475 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5478 2012-09-22 Kenichi Handa <handa@gnu.org>
5480 * composite.c (composition_reseat_it): Handle the case that a
5481 grapheme cluster is not covered by a single font (Bug#12352).
5483 2012-09-21 Chong Yidong <cyd@gnu.org>
5485 * image.c (define_image_type): Avoid adding duplicate types to
5486 image_types (Bug#12463). Suggested by Jörg Walter.
5488 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5490 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5491 (print_load_command_name): Add case LC_DATA_IN_CODE.
5492 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5494 2012-09-21 Glenn Morris <rgm@gnu.org>
5496 * eval.c (Frun_hook_with_args_until_success)
5497 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5499 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5501 * fileio.c (Ffile_selinux_context): Only call freecon when
5502 lgetfilecon succeeded.
5503 (Fset_file_selinux_context): Likewise. (Bug#12444)
5505 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5507 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5508 reordering, locate the cursor by calling set_cursor_from_row; if
5509 that fails, clear the desired glyph matrix before returning a
5510 failure indication to the caller. Fixes leaving garbled display
5511 when fast scrolling with a down-key. (Bug#12403)
5512 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5513 scrolling through multibyte text.
5515 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5517 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5518 calling mark_vectorlike since that's the one that marks the window.
5519 (mark_discard_killed_buffers): Mark the final cdr.
5520 * window.h (struct window): Move prev/next_buffers to the
5521 non-standard fields.
5522 * window.c (make_window): Initialize prev/next_buffers manually.
5524 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5526 Omit unused arg EXPECTED from socket hooks.
5527 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5528 * nsterm.m (ns_term_init):
5529 * termhooks.h (struct terminal.read_socket_hook):
5530 * w32inevt.c (w32_console_read_socket):
5531 * w32term.c (w32_read_socket):
5532 * xterm.c (XTread_socket):
5533 Omit unused arg EXPECTED. All callers changed.
5534 (store_user_signal_events): Return void, not int, since callers no
5535 longer care about the return value. All uses changed.
5537 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5539 * w32gui.h (XParseGeometry): Do not declare.
5541 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5543 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5544 Ignore 'expected'. See Eli Zaretskii in
5545 <http://bugs.gnu.org/12471#8> (last line).
5547 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5548 (XParseGeometry): Now static. Substitute extremal values for
5549 values that are out of range.
5551 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5553 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5555 * nsfns.m (XParseGeometry): Remove.
5556 (Fx_create_frame): Call x_set_offset to correctly interpret
5557 top_pos in geometry.
5559 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5560 (Fx_parse_geometry): If there is a space in string, call
5561 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5563 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5565 * search.c (scan_buffer): Use character positions in calls to
5566 region_cache_forward and region_cache_backward, not byte
5567 positions. (Bug#12196)
5569 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5570 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5572 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5573 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5574 emacs_blocked_malloc, now deleted.
5576 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5578 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5579 The workaround was for improving performance on Solaris 2.4, but
5580 is getting in the way now. Emacs will still work if someone is
5581 still running Solaris 2.4 in a museum somewhere; Sun dropped
5582 support for Solaris 2.4 in 2003.
5583 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5584 * process.c (create_process) [HAVE_WORKING_VFORK]:
5585 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5586 since Emacs no longer uses vfork on that platform.
5588 2012-09-17 Glenn Morris <rgm@gnu.org>
5590 * emacs.c: Use COPYRIGHT.
5592 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5594 Remove configure's --without-sync-input option (Bug#12450).
5595 When auditing signal-handling in preparation for cleaning it up,
5596 I found that SYNC_INPUT has race conditions and would be a real
5597 pain to fix. Since it's an undocumented and deprecated
5598 configure-time option, now seems like a good time to remove it.
5599 Also see <http://bugs.gnu.org/11080#16>.
5600 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5601 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5602 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5603 (malloc_hysteresis):
5604 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5605 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5606 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5607 (dont_register_blocks, bytes_used_when_reconsidered)
5608 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5609 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5610 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5611 Remove. All uses removed.
5612 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5613 implementation, one that depends on whether the new macro
5614 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5616 * atimer.c (run_timers, handle_alarm_signal):
5617 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5618 (handle_async_input, process_pending_signals)
5619 (handle_input_available_signal, init_keyboard):
5620 * nsterm.m (ns_read_socket):
5621 * process.c (wait_reading_process_output):
5622 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5623 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5625 * xterm.c (XTread_socket):
5627 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5628 * eval.c (handling_signal): Remove. All uses removed.
5629 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5630 All uses replaced with the SYNC_INPUT version.
5631 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5633 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5636 * font.c (Ffont_shape_gstring): Remove unused local.
5638 2012-09-16 Glenn Morris <rgm@gnu.org>
5640 * Makefile.in (clean): No longer run nextstep's clean.
5642 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5644 (ns-app): Move here from ns.mk, and simplify.
5645 (clean): Simplify nextstep entry.
5646 * ns.mk: Remove file.
5648 2012-09-17 Kenichi Handa <handa@gnu.org>
5650 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5651 not covert the last few charactes.
5653 2012-09-16 Kenichi Handa <handa@gnu.org>
5655 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5656 here, but just check the validity of glyphs in the glyph-string.
5658 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5660 * window.c (Fwindow_parameter, Fset_window_parameter):
5661 Accept any window as argument (Bug#12452).
5663 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5665 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5666 to ns_term_init to avoid memory leak.
5668 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5669 explicit retain/release.
5670 (ns_term_init): Only allow one display. Initialize outerpool and
5673 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5675 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5676 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5677 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5678 the Microsoft problem in a different way, by altering ../nt/config.nt.
5680 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5695 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5696 by lisp.h. This completes removal of setjmp.h inclusion
5697 erroneously announced in the previous commit. (Bug#12446)
5699 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5702 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5703 not defined as a macro. The latter happens on MS-Windows.
5706 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5708 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5709 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5710 Some instances of '#include <setjmp.h>' removed, if the
5711 only reason for the instance was because "lisp.h" was included.
5712 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5713 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5714 and _longjmp with the new symbols. Emacs already uses _setjmp if
5715 available, so this change affects only POSIXish hosts that have
5716 sigsetjmp but not _setjmp, such as some versions of Solaris and
5717 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5718 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5719 (png_load_body) [HAVE_PNG]:
5720 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5721 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5722 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5723 since PNG requires jmp_buf. This is the only exception to the
5724 general rule that we now use sys_setjmp and sys_longjmp.
5725 This exception is OK since this code does not change the signal
5726 mask or longjmp out of a signal handler.
5728 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5730 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5731 Include "syssignal.h", for 'main_thread'.
5733 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5735 Avoid out-of-range marker position (Bug#12426).
5736 * insdel.c (replace_range, replace_range_2):
5737 Adjust markers before overlays, as suggested by comments.
5738 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5739 Remove redundant check before calling offset_intervals.
5741 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5743 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5744 current buffer (Bug#12387).
5746 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5748 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5750 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5752 Use a more backwards-compatible timer format (Bug#12430).
5753 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5754 vector element, not from the 4th, since PSECS is now at the end.
5755 (Fcurrent_idle_time): Doc fix.
5757 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5759 Function to mark objects and remove killed buffers at once.
5760 * alloc.c (discard_killed_buffers): Rename to ...
5761 (mark_discard_killed buffers) ... new name. Add marking
5762 of remaining objects. Fix comment. Adjust users.
5763 (mark_object): Do not touch frame buffer lists here.
5764 * frame.c (delete_frame): Reset frame buffer lists here.
5766 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5768 Better workaround for GNOME bug when --enable-gcc-warnings.
5769 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5770 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5771 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5773 Simplify SIGIO usage (Bug#12408).
5774 The code that dealt with SIGIO was crufty and confusing, e.g., it
5775 played tricks like "#undef SIGIO" but these tricks were not used
5776 consistently. Simplify mostly by not #undeffing standard symbols,
5777 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5778 or not as we please) rather than "defined SIGIO" (standard symbol
5779 that we probably shouldn't #undef).
5780 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5781 Modules that need it can include it.
5782 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5783 * dispextern.h (ignore_sigio): New decl.
5784 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5785 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5786 * emacs.c (shut_down_emacs):
5787 * keyboard.c (kbd_buffer_store_event_hold):
5788 Use ignore_sigio rather than invoking 'signal' directly.
5789 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5791 (FIONREAD, SIGIO): Do not #undef.
5792 (tty_read_avail_input): Use #error rather than a syntax error.
5793 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5794 for I_PIPE, used by SETUP_SLAVE_PTY.
5795 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5796 * sysdep.c (croak): Remove; no longer needed. This bit of
5797 temporary code, with Fred N. Fish's comment that it's temporary,
5798 has been in Emacs since at least 1992!
5799 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5800 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5801 * syssignal.h (croak): Remove decl.
5802 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5803 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5804 now that we're termios-only.
5805 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5806 * term.c (dissociate_if_controlling_tty): Use #error rather than
5809 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5810 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5811 to work around GNOME bug 683906.
5812 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5813 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5814 This works around GCC bug 54561.
5816 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5818 More fixes for 'volatile' and setjmp/longjmp.
5819 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5820 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5821 (png_load_body) [HAVE_PNG]:
5822 (jpeg_load_body) [HAVE_JPEG]:
5823 New function, with most of the old parent function's body.
5824 (png_load) [HAVE_PNG]:
5825 (jpeg_load) [HAVE_JPEG]:
5826 Invoke the new function, to avoid longjmp munging our locals.
5827 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5828 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5829 longjmp is passed 2, as the C standard doesn't guarantee this.
5830 Instead, store the failure code into mgr->failure_code.
5832 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5834 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5835 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5836 (syms_of_keyboard): Remove support for unread-command-char.
5838 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5840 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5841 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5842 violation. (Bug#12426)
5844 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5846 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5848 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5850 * eval.c: Add `inhibit-debugger'.
5851 (Qinhibit_debugger): New symbol.
5852 (call_debugger): Bind it instead of Qdebug_on_error.
5853 (maybe_call_debugger): Test Vinhibit_debugger.
5854 (syms_of_eval): Define inhibit-debugger.
5855 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5856 (syms_of_xdisp): Remove inhibit-debug-on-message.
5858 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5860 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5861 If a nonvolatile local variable is written before a _longjmp to
5862 the frame containing the variable, and is read after the _longjmp,
5863 the value read is indeterminate. Some local variables of type
5864 'struct handler' and 'struct catchtag' are used in this way, so
5865 mark each of their slots as volatile if the slot can be set before
5866 _longjmp and read afterwards.
5867 * lisp.h (struct handler): var and chosen_clause are now volatile.
5868 (struct catchtag): val, next, and pdlcount are now volatile.
5870 * bidi.c (bidi_push_it, bidi_pop_it):
5871 * fns.c (copy_hash_table):
5872 * image.c (define_image_type):
5873 * keyboard.c (kbd_buffer_store_event_hold):
5874 * process.c (Fprocess_send_eof):
5875 * xfaces.c (x_create_gc) [HAVE_NS]:
5876 * xgselect.c (xg_select):
5877 Prefer assignment to memcpy when either will do.
5879 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5880 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5881 time an item is removed. No need to mark this function 'inline';
5882 the compiler knows better than we do.
5884 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5886 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5887 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5888 to change_frame_size (Bug#12388).
5889 (windowDidResize:): Pass YES to updateFrameSize.
5891 * nsterm.h: Add delay parameter to updateFrameSize.
5893 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5895 Discard killed buffers from deleted window and frame objects.
5896 This reduces an amount of references to killed buffers and
5897 helps GC to reclaim them faster.
5898 * alloc.c (discard_killed_buffers): New function.
5899 (mark_object): Use it for deleted windows and frames.
5900 (mark_object): If symbol's value is set up for a killed buffer
5901 or deleted frame, restore its global binding.
5902 * data.c (swap_in_global_binding): Add GC notice.
5903 (swap_in_symval_forwarding): Use convenient set_blv_where.
5904 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5905 * window.h: ... to here.
5907 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5909 Convenient macro to check whether the buffer is live.
5910 * buffer.h (BUFFER_LIVE_P): New macro.
5911 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5912 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5914 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5916 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5917 composition cases (Bug#12364).
5919 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5920 overhang of succeeding glyphs overlapping box cursor.
5922 * w32term.c (x_draw_glyph_string): Likewise.
5924 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5926 Simplify, document, and port floating-point (Bug#12381).
5927 The porting part of this patch fixes bugs on non-IEEE platforms
5928 with frexp, ldexp, logb.
5929 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5931 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5932 support, by removing commented-out code and briefly listing the
5933 C89 functions excluded. The commented-out stuff was confusing
5934 maintenance, e.g., we thought we needed cbrt but it was commented out.
5935 (logb): Remove decl; no longer needed.
5936 (isfinite): New macro, if not already supplied.
5937 (isnan): Don't replace any existing macro.
5938 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5939 are present on all C89 platforms.
5940 (Ffrexp): Do not special-case zero, as frexp does the right thing
5942 (Flogb): Do not use logb, as it doesn't have the desired meaning
5943 on hosts that use non-base-2 floating point. Instead, stick with
5944 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5945 frexp, to avoid getting an unspecified result.
5947 * xdisp.c (Qinhibit_debug_on_message): Now static.
5949 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5951 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5952 NSBezierPath (Bug#12131).
5954 2012-09-10 Chong Yidong <cyd@gnu.org>
5956 * fns.c (Fdelq, Fdelete): Doc fix.
5958 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5960 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5961 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5963 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5965 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5966 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5969 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5971 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5972 left fringe if the window has a left margin. This avoids leaving
5973 traces of the cursor because its leftmost pixel is not drawn over.
5975 * dispnew.c (update_window_line): When the left margin area of a
5976 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5977 that screen line. (Bug#12277)
5979 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5981 Assume C89 or later for math functions (Bug#12381).
5982 This simplifies the code, and makes it a bit smaller and faster,
5983 and (most important) makes it easier to clean up signal handling
5984 since we can stop worring about floating-point exceptions in
5985 library code. That was a problem before C89, but the problem
5986 went away many years ago on all practical Emacs targets.
5987 * data.c, image.c, lread.c, print.c:
5988 Don't include <math.h>; no longer needed.
5989 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5990 might be autoconfigured, as that never happens.
5992 * doprnt.c (DBL_MAX_10_EXP):
5993 * print.c (DBL_DIG):
5994 Remove. C89 or later always defines these.
5995 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5996 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5997 (arith_error, domain_error, domain_error2):
5998 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5999 no longer needed -- we simply return what C returns. All uses removed.
6000 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6002 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6003 Remove. All uses expanded, as these macros are no longer used
6004 more than once and are now more trouble than they're worth.
6005 (Ftan): Use tan, not sin / cos.
6006 (Flogb): Assume C89 frexp.
6007 (fmod_float): Assume C89 fmod.
6008 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6009 (init_floatfns): Remove. All uses removed.
6011 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6013 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6014 compositeToPoint for OSX < 10.6 (Bug#12390).
6016 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6018 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6019 This produces more-accurate results.
6021 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6023 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6024 changes (Bug#12088).
6026 2012-09-08 Chong Yidong <cyd@gnu.org>
6028 * syntax.c (Fstring_to_syntax): Doc fix.
6030 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6032 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6033 in the internal border.
6034 (x_set_window_size): Remove static variables and their usage.
6035 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6036 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6037 Remove fringe/internal border adjustment (Bug#11052).
6038 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6039 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6040 (ns_fix_rect_ibw): Remove.
6041 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6042 (ns_dumpglyphs_box_or_relief): Ditto.
6043 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6045 (ns_dumpglyphs_image): Ditto.
6046 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6048 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6049 their usage. Add fringe_extended_p and its use as in other terms.
6050 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6051 scroll bar was removed.
6052 (updateFrameSize): New function.
6053 (windowDidResize): Move code to updateFrameSize and call it.
6055 * nsterm.h (EmacsView): Add updateFrameSize.
6057 2012-09-07 Chong Yidong <cyd@gnu.org>
6059 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6061 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6063 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6065 More signal-handler cleanup (Bug#12327).
6066 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6067 Problem introduced when merging patches. Noted by Eli Zaretskii in
6068 <http://bugs.gnu.org/12327#67>.
6069 * floatfns.c: Comment fix.
6070 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6071 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6072 and anyway the declaration is harmless even if SIGDANGER is not defined.
6073 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6074 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6075 source files not surprisingly expected syssignal.h to define, or
6076 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6077 Include <sys/ioctl.h>, for FIONREAD.
6078 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6079 This eliminates a problem whereby other files mysteriously had
6080 to include "syssignal.h" before including "systty.h" if they
6081 wanted to use "#ifdef SIGIO".
6083 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6085 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6087 * w32.c (sigemptyset): Empty the set.
6088 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6090 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6092 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6094 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6095 (mark_object): Likewise for frame objects.
6097 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6099 * syssignal.h (handle_on_main_thread): Always declare,
6100 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6101 This ports to platforms without HAVE_PTHREAD.
6103 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6105 Signal-handler cleanup (Bug#12327).
6106 Emacs's signal handlers were written in the old 4.2BSD style with
6107 sigblock and sigmask and so forth, and this led to some
6108 inefficiencies and confusion. Rewrite these to use
6109 pthread_sigmask etc. without copying signal sets around. Also,
6110 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6111 'signal', and instead use functions that do not attempt to take
6112 over the system name space. This patch causes Emacs's text
6113 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6114 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6115 Do not include <signal.h> or "syssignal.h", as these
6116 modules do not use signals.
6117 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6118 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6119 Do not include <signal.h>, as "syssignal.h" does that for us now.
6120 * atimer.c (sigmask_atimers): New function.
6121 (block_atimers, unblock_atimers): New functions,
6122 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6124 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6125 no longer needed here.
6126 * emacs.c (main): Inspect existing signal handler with sigaction,
6127 so that there's no need to block and unblock SIGHUP.
6128 * sysdep.c (struct save_signal): New member 'action', replacing
6129 old member 'handler'.
6130 (save_signal_handlers, restore_signal_handlers):
6131 Use sigaction instead of 'signal' to save and restore.
6132 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6133 New function. All users of 'signal' modified to use set_sighandler
6134 if they're writeonly, and to use sys_signal if they're read+write.
6135 (emacs_sigaction_init, forwarded_signal): New functions.
6136 (sys_signal): Remove. All uses replaced by calls to sigaction
6137 and emacs_sigaction_init, or by direct calls to 'signal'.
6138 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6139 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6140 all uses replaced by pthread_sigmask etc. calls.
6141 * syssignal.h: Include <signal.h>.
6142 (emacs_sigaction_init, forwarded_signal): New decls.
6143 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6144 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6145 (sigmask, sys_sigmask): Remove; no longer needed.
6146 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6147 (sigblock, sigunblock, sigfree):
6148 (sigsetmask) [!defined sigsetmask]:
6149 Remove. All uses replaced by pthread_sigmask.
6150 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6151 no longer need to be replaced, and its typical old uses
6152 are now done via emacs_sigaction_init and sigaction.
6153 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6154 (sys_sigdel): Remove; unused.
6155 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6157 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6159 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6160 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6162 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6164 Explicitly mark buffer_defaults and buffer_local_symbols.
6165 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6166 mark_local_symbols here.
6167 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6168 since special buffers aren't marked here any more.
6169 (allocate_buffer): Chain new buffer with all_buffers here...
6170 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6172 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6173 (syms_of_buffer): Remove staticpro of the above.
6174 (init_buffer_once): Set names for buffer_defaults and
6175 buffer_local_symbols.
6177 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6179 Use bool for booleans in font-related modules.
6180 * font.c (font_intern_prop, font_style_to_value)
6181 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6182 (generate_otf_features, font_check_otf_features, font_check_otf)
6183 (font_match_p, font_list_entities, font_at):
6184 * fontset.c (fontset_id_valid_p, reorder_font_vector
6185 (fontset_find_font, Fset_fontset_font)
6186 (face_suitable_for_char_p) [0]:
6187 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6188 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6189 (m17n_flt_initialized, ftfont_shape_by_flt):
6190 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6191 * nsfont.m (nsfont_draw):
6192 * w32font.c (w32font_draw):
6193 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6194 Use bool for booleans.
6195 * font.h: Adjust to above API changes.
6196 (struct font, struct font_driver, struct font_driver_list):
6197 Use bool for booleans.
6198 (struct font): Remove useless member encoding_type.
6200 * fontset.c, xftfont.c: Omit unnecessary static decls.
6202 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6204 * alloc.c (mark_object): Revert window marking code
6205 since it's unsafe for the Fset_window_configuration.
6207 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6209 Fix race conditions with signal handlers and errno (Bug#12327).
6210 Be more systematic about preserving errno whenever a signal
6211 handler returns, even if it's not in the main thread. Do this by
6212 renaming signal handlers to distinguish between signal delivery
6213 and signal handling. All uses changed.
6214 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6215 * data.c (deliver_arith_signal): Rename from arith_error.
6216 * dispnew.c (deliver_window_change_signal): Rename from
6217 window_change_signal.
6218 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6219 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6220 * keyboard.c (deliver_input_available_signal): Rename from
6221 input_available_signal.
6222 (deliver_user_signal): Rename from handle_user_signal.
6223 (deliver_interrupt_signal): Rename from interrupt_signal.
6224 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6225 (deliver_child_signal): Rename from sigchld_handler.
6226 * atimer.c (handle_alarm_signal):
6227 * data.c (handle_arith_signal):
6228 * dispnew.c (handle_window_change_signal):
6229 * emacs.c (handle_fatal_signal, handle_danger_signal):
6230 * keyboard.c (handle_input_available_signal):
6231 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6232 * process.c (handle_pipe_signal, handle_child_signal):
6233 New functions, with the actual signal-handling code taken from the
6234 original respective signal handlers, sans the sporadic attempts to
6235 preserve errno, since that's now done by handle_on_main_thread.
6236 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6237 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6238 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6240 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6241 Move initialization of main_thread to sysdep.c's init_signals.
6242 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6243 our usage, and simplifies the mainline code.
6244 (record_child_status_change): New static function, as a helper
6245 for handle_child_signal, and with most of the old child handler's
6247 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6248 (handle_child_signal): Use the above.
6249 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6250 Moved here from emacs.c.
6251 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6252 code moved here from emacs.c's main function.
6253 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6254 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6255 This lets callers save and restore errno properly.
6257 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6259 Remove redundant or unused things here and there.
6260 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6261 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6262 * editfns.c (Fcompare_buffer_substrings): Likewise.
6263 * frame.h (struct terminal, struct font_driver_list):
6264 Remove redundant declarations.
6265 * window.h (Qleft, Qright): Likewise.
6267 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6269 Do not mark objects from deleted buffers, windows and frames.
6270 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6271 (mark_object): Likewise for windows and frames.
6273 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6275 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6276 buffer_defaults and buffer_local_symbols as valid objects.
6277 Return special value to denote them.
6279 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6281 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6282 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6283 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6284 (file_name_absolute_p, Fsubstitute_in_file_name):
6285 (check_executable, check_writable, Ffile_accessible_directory_p)
6286 (Fset_file_selinux_context, Fdefault_file_modes)
6287 (Finsert_file_contents, choose_write_coding_system)
6288 (Fwrite_region, build_annotations, a_write, e_write)
6290 * filelock.c (boot_time_initialized, get_boot_time)
6291 (get_boot_time_1, lock_file_1, within_one_second):
6292 * floatfns.c (in_float):
6293 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6294 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6295 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6296 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6297 * window.c (compare_window_configurations):
6298 Use bool for booleans.
6299 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6300 (Fdefault_file_modes): Now mode_t, not int, for modes.
6301 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6302 (internal_delete_file): Now returns void, not a (boolean) int,
6303 since nobody was looking at the return value.
6304 * lisp.h, window.h: Adjust to above API changes.
6306 * xdisp.c (set_message): Simplify and reindent last change.
6308 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6310 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6312 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6314 * eval.c (call_debugger): Make the function non-static so that we
6315 can call it from set_message.
6317 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6318 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6320 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6322 Give more-useful info on a fatal error (Bug#12328).
6323 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6324 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6325 of doing the work ourselves.
6326 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6327 do most of the work.
6328 (fatal_error_backtrace): New function, taken from the guts
6329 of the old fatal_error_signal, but with a new option to output
6331 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6332 info about the signal than just its number.
6333 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6334 * sysdep.c: Include <execinfo.h>
6335 (emacs_backtrace): New function, taken partly from the previous
6336 code of the 'die' function.
6337 (emacs_abort): Call fatal_error_backtrace rather than abort.
6339 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6341 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6342 eager (load-time) macro-expansion.
6343 * lisp.mk (lisp): Add macroexp.
6345 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6347 Simplify redefinition of 'abort' (Bug#12316).
6348 Do not try to redefine the 'abort' function. Instead, redo
6349 the code so that it calls 'emacs_abort' rather than 'abort'.
6350 This removes the need for the NO_ABORT configure-time macro
6351 and makes it easier to change the abort code to do a backtrace.
6352 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6353 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6354 Remove; sysdep.c's emacs_abort now takes its place.
6355 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6356 'abort' changed to use 'emacs_abort'.
6357 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6358 (abort) [!defined abort]: Rename to ...
6359 (emacs_abort): ... new name.
6360 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6361 the place of the old 'abort' in emacs.c.
6362 * w32.c, w32fns.c (abort): Do not #undef.
6363 * w32.c (emacs_abort): Rename from w32_abort.
6365 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6367 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6368 offsets[j].dv, since the y axis of the screen coordinates points
6369 down, while the y axis of the font definition coordinates points
6370 up. This fixes display of Arabic diacritics such as KASRA and
6371 KASRATAN. (Bug#11860)
6373 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6375 Be more systematic about _setjmp vs setjmp.
6376 * alloc.c (test_setjmp, mark_stack):
6377 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6378 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6379 (png_load, my_error_exit, jpeg_load):
6380 * process.c (send_process_trap, send_process):
6381 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6382 The underscored versions are up to 30x faster on some hosts.
6383 Formerly, the code used setjmp+longjmp sometimes and
6384 _setjmp+_longjmp at other times, with no particular reason to
6385 prefer setjmp+longjmp.
6387 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6389 Fix minor problem found by static checking.
6390 * buffer.c (Fdelete_all_overlays): Return nil.

6519 offset adjustment values separately for each cluster. (Bug#11860)
6521 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6522 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6523 about implicit conversions from integer to pointer.

6581 window system declarations.
6583 * frame.h: Move common functions here: set_frame_menubar,
6584 x_set_window_size, x_sync, x_get_focus_frame,

6837 buffer doesn't appear in the selected window, go to its old
6840 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6842 Special MEM_TYPE_SPARE to denote reserved memory.
6843 * alloc.c (enum mem_type): New memory type.
6844 (refill_memory_reserve): Use new type for spare memory.
6845 This prevents live_cons_p and live_string_p from incorrect
6846 detection of uninitialized objects from spare memory as live.
6848 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6851 * Makefile.in (.PHONY): versioclean -> versionclean.
6853 Remove unused external symbols.
6854 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6855 * window.c (Qwindow_valid_p, decode_valid_window):
6856 Now static, not extern.
6857 * data.c (Qinterval): Remove; unused.
6858 (syms_of_data): Do not define 'interval'.
6859 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6860 * window.h (decode_valid_window):
6863 * character.c, charset.c, chartab.c: Use bool for booleans.
6864 * character.c (lisp_string_width, string_count_byte8)
6865 (string_escape_byte8):
6866 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6867 (load_charset_map_from_file, map_charset_chars)
6868 (Fdefine_charset_internal, define_charset_internal)
6869 (Fdeclare_equiv_charset, find_charsets_in_text)
6870 (Ffind_charset_region, char_charset, Fiso_charset):
6871 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
6872 (sub_char_table_set, sub_char_table_set_range)
6873 (char_table_set_range, optimize_sub_char_table)
6874 (map_sub_char_table):
6875 Use bool for boolean.
6876 * character.c (str_to_unibyte): Omit last boolean argument; it was
6877 always 0. All callers changed.
6878 * character.h, charset.h: Adjust to match previous changes.
6879 * character.h (char_printable_p): Remove decl of nonexistent function.
6880 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6881 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6882 are all boolean, so make them single-bit bitfields.
6884 * lisp.h (ASET): Remove attempt to detect side effects.
6885 It was meant to be temporary and it often doesn't work,
6886 because when IDX has side effects the behavior of IDX==IDX
6887 is undefined. See Stefan Monnier in
6888 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6890 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6892 * lisp.h (functionp): New function (extracted from Ffunctionp).
6893 (FUNCTIONP): Use it.
6894 * eval.c (Ffunctionp): Use it.
6896 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6898 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6899 as that's faster and simpler than static storage. Don't bother
6900 with the g_main_context_query overhead if g_main_context_pending
6901 says no events are pending.
6902 (gfds, gfds_size): Remove these static vars.
6903 (xgselect_initialize): Remove; no longer needed.
6904 All uses and decls removed.
6906 * emacs.c (fatal_error_signal_hook): Remove.
6907 All uses removed. This leftover from old code was always 0.
6909 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6910 * casefiddle.c (casify_object, casify_region):
6911 * casetab.c (set_case_table):
6912 * category.c, category.h (word_boundary_p):
6913 * category.h (CHAR_HAS_CATEGORY):
6914 Use bool for booleans, instead of int.
6916 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6918 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6920 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6922 On assertion failure, print backtrace if available.
6923 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6924 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6925 * Makefile.in (LIB_EXECINFO): New macro.
6928 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6929 * bytecode.c (exec_byte_code):
6930 * callint.c (check_mark, Fcall_interactively):
6931 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6932 (getenv_internal, sync_process_alive, call_process_exited):
6933 * lisp.h (USE_SAFE_ALLOCA):
6934 Use bool for booleans, instead of int.
6935 * lisp.h, process.h: Adjust prototypes to match above changes.
6936 * callint.c (Fcall_interactively): Don't assume the mark's
6937 offset fits in 'int'.
6939 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6941 * buffer.c, buffer.h: Use bool for boolean.
6942 * buffer.c (reset_buffer_local_variables)
6943 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6944 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6945 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6946 (overlay_touches_p, overlay_strings, Foverlay_put)
6947 (report_overlay_modification, call_overlay_mod_hooks):
6948 (mmap_enlarge, mmap_set_vars):
6949 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6950 Use bool for booleans, instead of int.
6951 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6952 since the 1-or-0 return value is always ignored anyway.
6953 (mmap_initialized_p):
6954 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6955 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6957 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6959 * bidi.c: Use bool for boolean.
6960 This is a bit more readable, and makes the text segment of bidi.o
6961 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6962 Presumably it's faster too.
6963 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6965 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6966 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6967 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6968 (bidi_explicit_dir_char, bidi_level_of_next_char)
6969 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6970 Use bool for booleans, instead of int.
6971 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6972 (bidi_unshelve_cache): Adjust decls to match code.
6974 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6976 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6979 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6981 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6982 * atimer.h: Include <stdbool.h>.
6984 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6986 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6987 compile time tests instead of run time tests on systems that do
6989 (FRAME_MAC_P): Remove leftover from deleted code.
6990 * frame.c (syms_of_frame): Remove leftover from deleted code.
6992 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6994 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6996 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6998 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6999 Otherwise, the compiler complains about (A?B:C) where B is void
7000 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7001 (fontset_add): Return void, for FONTSET_ADD.
7003 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7005 * alloc.c: Use bool for booleans.
7006 (gc_in_progress, abort_on_gc)
7007 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7008 (dont_register_blocks) [GC_MALLOC_CHECK]:
7009 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7010 (check_string_bytes, make_specified_string, memory_full)
7011 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7012 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7013 (mark_stack, valid_pointer_p, make_pure_string)
7014 (Fgarbage_collect, survives_gc_p, gc_sweep):
7015 Use bool for booleans, instead of int.
7016 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7017 Remove unused local.
7018 * alloc.c (PURE_POINTER_P):
7019 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7020 * editfns.c (Fformat):
7021 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7023 * fns.c (sweep_weak_table):
7024 * lisp.h (suppress_checking, push_message, survives_gc_p)
7025 (make_pure_string, gc_in_progress, abort_on_gc):
7026 * lread.c (readchar, read1):
7027 * print.c (Fprin1_to_string):
7028 * xdisp.c (push_message):
7029 Use bool for booleans affected directly or indirectly by
7032 Make recently-introduced setters macros.
7033 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7034 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7035 (set_fontset_default, set_fontset_fallback): Rename from their
7036 upper-case counterparts, and make them functions rather than macros.
7037 This is more consistent with the other recently-introduced setters.
7038 These don't need to be inline, since they're local.
7040 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7042 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7043 the loop (Bug#12247).
7045 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7047 * lisp.h (vcopy): Use memcpy rather than our own loop.
7048 This fixes a performance regression introduced by the recent
7049 addition of vcopy. This means 'vcopy' will need to be modified
7050 for a copying collector, but that's OK. Also, tighten the
7051 checking in the assertion.
7053 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7055 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7056 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7057 non-base glyph for the width of the base character, according to
7058 what x_draw_composite_glyph_string_foreground expects.
7059 Generate WADJUST value according to composition_gstring_width's
7060 expectations, to produce correct width of the composed character.
7061 Reverse the sign of the DU offset produced by ScriptPlace.
7063 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7065 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7067 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7069 Avoid direct writes to contents member of struct Lisp_Vector.
7070 * lisp.h (vcopy): New function to copy data into vector.
7071 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7072 * fns.c (Ffillarray): Use ASET.
7073 * keyboard.c (timer_check_2): Use AREF and ASET.
7074 (append_tool_bar_item, Frecent_keys): Use vcopy.
7075 * lread.c (read_vector): Use ASET.
7076 * msdos.c (Frecent_doskeys): Use vcopy.
7077 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7078 (Finternal_merge_in_global_face): Use ASET and vcopy.
7079 * xfont.c (xfont_list_pattern): Likewise.
7081 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7083 * window.c (Fwindow_point): For the selected window always return
7084 the position of its buffer's point.
7085 (Fset_window_point): For the selected window always go in its
7086 buffer to the specified position.
7088 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7090 Setter macros for fontsets.
7091 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7092 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7093 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7096 2012-08-20 Glenn Morris <rgm@gnu.org>
7098 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7099 Don't assume that `ln -f' works.
7101 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7103 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7104 and later about non-assignments with no effect. See discussion at
7105 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7108 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7110 Inline setter functions for Lisp_Objects slots of struct specbinding.
7111 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7114 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7116 * window.c (select_window): Always make selected window's buffer
7119 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7121 Use AREF and ASET for docstrings of category tables.
7122 * category.h (CATEGORY_DOCSTRING): Use AREF.
7123 (SET_CATEGORY_DOCSTRING): Use ASET.
7124 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7126 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7128 Inline setter functions for hash table members.
7129 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7130 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7131 (set_hash_key_and_value, set_hash_index, set_hash_next)
7132 (set_hash_hash): New functions.
7133 * charset.c, fns.c: Adjust users.
7135 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7137 Inline getter and setter functions for per-buffer values.
7138 * buffer.h (per_buffer_default, set_per_buffer_default)
7139 (per_buffer_value, set_per_buffer_value): New functions.
7140 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7141 * buffer.c, data.c: Adjust users.
7143 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7145 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7147 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7149 Rely on <config.h> + <unistd.h> to declare 'environ',
7150 as gnulib does this if the system doesn't.
7151 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7152 Remove declaration. MS-Windows declares it on stdlib.h which is
7153 included by conf_post.h.
7154 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7155 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7156 * vm-limit.c: Include <unistd.h>, for 'environ'.
7158 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7159 (start_of_data): Remove decl; mem-limits.h provides it.
7161 * xdisp.c (handle_invisible_prop): Make it a bit faster
7162 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7164 2012-08-19 Chong Yidong <cyd@gnu.org>
7166 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7169 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7171 * .gdbinit: Use call instead of set when calling a function in the
7174 * data.c (set_internal): Don't use set_blv_found.
7175 (Fkill_local_variable): Likewise.
7177 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7179 * nsfont.m (ns_ascii_average_width): Ensure the string
7180 ascii_printable is initialized with a null-terminated character
7181 array. Otherwise, it can contain undesired extra characters.
7183 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7185 port new setting code to Sun C 5.8 2005/10/13
7186 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7187 Return void, not Lisp_Object. Otherwise, the compiler
7188 complains about (A?B:C) where B is void and C is Lisp_Object
7189 when compiling CHAR_TABLE_SET, due to the recent change to
7190 the API of sub_char_table_set_contents.
7192 2012-08-18 Chong Yidong <cyd@gnu.org>
7194 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7195 for the string case (Bug#3874).
7197 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7199 * buffer.h (BSET): Remove (Bug#12215).
7200 Replace all uses with calls to new setter functions.

7229 * syntax.c (bset_syntax_table):
7230 New setter functions.
7232 * process.h (PSET): Remove (Bug#12215).
7233 Replace all uses with calls to new setter functions.

7237 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
7238 * process.c (PROCESS_INLINE):

7244 (pset_plist, pset_sentinel, pset_status, pset_tty_name)
7245 (pset_type, pset_write_queue): New setter functions.
7247 * window.h (WSET): Remove (Bug#12215).
7248 Replace all uses with calls to new setter functions.
7249 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
7250 (WINDOW_INLINE): New macro.

7254 (wset_window_end_pos, wset_window_end_valid)
7255 (wset_window_end_vpos): New setter functions.

8027 value of EMACSLOADPATH, as it is no longer needed.
8028 (check_windows_init_file): Now external, not static.

8034 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

8079 * alloc.c (record_xmalloc): New function.
8080 * lisp.h (record_xmalloc): New decl.
8081 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8082 more like a function. This is because the pointer cast is not
8083 needed. All uses changed.
8084 * print.c (print_string, print_error_message): Avoid length recalc.
8086 Improve fix for macroexp crash with debugging (Bug#12118).
8087 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to

8121 with addition of handling of symlinks and support for 'lstat'.
8122 If possible, get file's attributes and security information by
8123 handle, not by name. Produce S_IFLNK bit for symlinks, when
8124 called from 'lstat'.
8125 (stat, lstat): New functions, call 'stat_worker'.
8126 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8127 symlinks when the underlying filesystem supports them.
8129 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8131 Fix macroexp crash on Windows with debugging (Bug#12118).
8132 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8133 checking subscripts; problem introduced with the recent
8134 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8135 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8136 since it's used in non-static inline functions now.
8138 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8139 Don't assume buffer size fits in 'int'. Remove unused local.

8606 * alloc.c (listn): Fix the order the arguments are consed onto the
8609 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
8610 enumeration constants, as PURE and HEAP are too general, and clash
8611 with other headers and sources, such as gmalloc.c and the
8612 MS-Windows system headers. All users changed.
8614 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8616 Revert last save_excursion_save and save_excursion_restore changes.
8617 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

8627 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
8629 Improve GDB symbol export (Bug#12036).
8630 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8631 arms of an 'if', not using conditional expressions; otherwise GDB
8632 complains about the types in the unevaluated arm when the argument
8633 is an integer literal.
8634 (xgetint): Simplify expression.
8635 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8636 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8637 Zaretskii in <http://bugs.gnu.org/12036#13>.
8638 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8639 needed now that we have gdb_make_enums_visible.
8640 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8641 (enum enum_USE_LSB_TAG):
8642 New enum types, packaging up enums that need to be exported to GDB.
8644 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8646 Utility function to make a list from specified amount of objects.

8648 (listn): New prototype.
8649 * alloc.c (listn): New function.

8660 * xdisp.c (syms_of_xdisp): Likewise.
8661 * xfns.c (syms_of_xfns): Likewise.
8663 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8665 Fast save_excursion_save and save_excursion_restore.
8666 * lisp.h (struct Lisp_Excursion): New data type.
8667 (PVEC_EXCURSION): New pseudovector type.
8668 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8669 to deal with it. Adjust comments.
8670 (init_marker, attach_marker): New prototype.
8671 (unchain_marker): Adjust prototype.
8672 * marker.c (attach_marker): Change to global.

8680 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8682 Fix export of symbols to GDB (Bug#12036).
8683 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
8684 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8685 emacs.c, as this is a more-suitable home. Had this been done earlier
8686 the fix for 12036 would have avoided some of the problems noted in
8687 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8688 would have been more obvious.
8689 * emacs.c: Do not include <verify.h>; no longer needed.
8690 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8691 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8692 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8693 Remove; now done in lisp.h.
8694 * lisp.h (PUBLISH_TO_GDB): New macro.
8695 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
8696 (DATA_SEG_BITS): Use it.
8697 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8698 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8699 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8700 not be usable in #if. This simplifies things.
8702 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8704 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8706 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
8708 Simplify export of symbols to GDB (Bug#12036).
8709 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8710 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8711 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8712 Adjust to changes in lisp.h and emacs.c, by using
8713 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8714 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8715 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8716 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8717 instead of gdb_valbits.
8718 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8719 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8720 instead of gdb_array_mark_flag.
8721 (xboolvector): Get size from $->size, not $->header.size.
8722 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8723 (xreload, hook-run, hookpost-run): Remove.
8724 * emacs.c: Include <verify.h>.
8725 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8726 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8728 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8729 (gdb_USE_LSB_TAG): New enum constants.
8730 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8731 Also define these as enum constants, so they're visible to GDB.
8732 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8733 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8734 as constants, so they're visible to GDB.
8735 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8736 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8737 Now enum constants, not macros, so they're visible to GDB.
8738 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8739 more convenient now. All uses changed.
8740 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8741 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8743 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8748 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
8750 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8751 add argument, tune behavior, and adjust all callers.
8753 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8755 Use typedef for EMACS_INT, EMACS_UINT.
8756 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8757 than macros. This simplifies debugging in the usual case, since
8758 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8759 and it allows expressions involving EMACS_INT casts.
8760 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8762 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8772 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8774 Adjust buffer text indirection counters at the end of Fkill_buffer.
8775 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8776 buffer is definitely dead. This should really fix an issue reported
8777 by Christoph Scholtes again. (Bug#12007).
8778 (init_buffer_once): Initialize indirection counters of
8779 buffer_defaults and buffer_local_symbols (for sanity and safety).
8781 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8783 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8784 and continuation glyphs on tooltip frames, leave them at zero.
8785 Avoids continued lines in tooltips. (Bug#11832)
8787 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
8789 Simplify copy_overlay.
8790 * buffer.c (copy_overlay): Simplify. Use build_marker.

8812 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8814 Swap buffer text indirection counters in Fbuffer_swap_text.
8815 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8816 This avoids crash reported by Christoph Scholtes at
8817 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8819 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8821 * nsmenu.m (Popdown_data): New struct.
8822 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8824 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

8826 and autorelease them. Also autorelease img and matrix (Bug#12005).
8827 (dealloc): Remove (Bug#12005).

8844 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8846 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8847 as it's limited by the amount of memory, not by INT_MAX.
8849 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8851 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8852 in special-event-map. See the discussion at

8911 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8912 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8913 Adjust users accordingly.

8932 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
8933 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
8934 'for_each_per_buffer_object_at'.
8935 All uses changed. It's better to use upper-case for macros that
8936 cannot be implemented as functions, to give the reader a clue
8937 that they're special.
8939 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
8941 * alloc.c (Fgarbage_collect): Tweak docstring.

8982 * intervals.c (merge_interval_right, merge_interval_left):
8983 Do not zero out this interval if it is absorbed by its children,
8984 as this interval's total length doesn't change in that case. See
8985 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
8987 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
8989 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
8990 when invoking (make-bool-vector N t) and N is a positive
8991 multiple of 8 -- the last 8 bits were mistakenly cleared.
8993 Remove some struct layout assumptions in bool vectors.
8994 * alloc.c (bool_header_size): New constant.
8995 (header_size, word_size): Move earlier, as they're now used earlier.

8998 padding before the data member of a bool vector.
8999 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
9000 than doing the check by hand with an abort ().
9002 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9004 * eval.c (Fdefvar): Don't check constants since we only set the var if
9005 it's not yet defined anyway (bug#11904).
9007 * lisp.h (last_undo_boundary): Declare new var.
9008 * keyboard.c (command_loop_1): Set it.
9009 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
9010 were auto-added by the command loop (bug#11774).
9012 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
9014 * w32font.c (Qsymbol): Remove local definition.

9503 2012-07-11 Glenn Morris <rgm@gnu.org>
9505 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
9506 since nothing has defined it on these platforms.
9508 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
9509 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

9513 Move CLASH_DETECTION to configure.
9515 * s/gnu.h: Remove file, which is now empty.
9517 * s/gnu.h, s/gnu-linux.h:
9518 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
9520 2012-07-11 John Wiegley <johnw@newartisans.com>
9522 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
9523 function attribute, so we only use it if it exists in the
9526 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
9528 Avoid call to strlen in fast_c_string_match_ignore_case.
9529 * search.c (fast_c_string_match_ignore_case): Change to use
9530 length argument. Adjust users accordingly.
9531 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
9533 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

9574 Remove "#define unix" that is no longer needed (Bug#11905).
9575 * s/aix4-2.h (unix): Remove; no longer needed.
9577 EMACS_TIME simplification (Bug#11875).
9578 This replaces macros (which typically do not work in GDB)
9579 with functions, typedefs and enums, making the code easier to debug.
9580 The functional style also makes code easier to read and maintain.
9581 * systime.h: Include <sys/time.h> on all hosts, not just if
9582 WINDOWSNT, since 'struct timeval' is needed in general.
9583 (EMACS_TIME): Now a typedef, not a macro.
9584 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9586 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

9589 (EMACS_TIME_LE): Now functions, not macros.
9590 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9591 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9592 which are not functions. All uses rewritten to use:
9593 (make_emacs_time): New function.
9594 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9595 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9596 not functions. All uses rewritten to use the following, respectively:
9597 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9598 (add_emacs_time, sub_emacs_time): New functions.
9599 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9600 * fileio.c (Fcopy_file):
9601 * xterm.c (XTflash): Get the current time closer to when it's used.
9602 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

9609 * frame.c (Fmake_terminal_frame):
9610 * gtkutil.c (get_utf8_string):
9612 * nsmenu.m (ns_update_menubar):
9613 * regex.c (regerror):
9614 Prefer memcpy to strncpy and strncat when either will do.
9615 * fileio.c (Fsubstitute_in_file_name):
9616 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
9617 (menu_separator_name_p):
9618 * nsmenu.m (ns_update_menubar):
9619 Prefer memcmp to strncmp when either will do.
9620 * nsterm.m: Include <ftoastr.h>.
9622 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9623 Prefer snprintf to strncpy.
9624 * nsterm.m (ns_term_init):
9625 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9626 * nsterm.m (ns_term_init):
9627 Avoid the need for strncpy, by using build_string or
9628 make_unibyte_string directly. Use dtoastr, not snprintf.
9629 * process.c (Fmake_network_process): Diagnose service names that
9630 are too long, rather than silently truncating them or creating
9631 non-null-terminated names.
9632 (Fnetwork_interface_info): Likewise, for interface names.
9633 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9634 Prefer sprintf to strncat.
9635 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
9636 Prefer vsnprintf to vsprintf + strncpy.
9638 2012-07-10 Glenn Morris <rgm@gnu.org>
9640 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
9641 Clarify fallback case.
9643 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9645 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
9646 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9647 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9648 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9649 where argument type is known to be a Lisp_Cons.
9651 2012-07-10 Tom Tromey <tromey@redhat.com>
9653 * bytecode.c (BYTE_CODE_THREADED): New macro.
9654 (BYTE_CODES): New macro. Replaces all old byte-code defines.

9661 Optimize pure C strings initialization.
9662 * lisp.h (make_pure_string): Fix prototype.
9663 (build_pure_c_string): New function, defined as static inline. This
9664 provides a better opportunity to optimize away calls to strlen when
9665 the function is called with compile-time constant argument.
9666 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
9667 argument, adjust users accordingly. Use build_pure_c_string where
9669 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
9670 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
9671 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
9673 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9675 Avoid calls to strlen in miscellaneous functions.
9676 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
9677 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
9678 * lread.c (openp): Likewise.
9680 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
9682 Avoid calls to strlen in path processing functions.
9683 * fileio.c (file_name_as_directory): Add comment. Change to add
9684 srclen argument and return the length of result. Adjust users
9686 (directory_file_name): Fix comment. Change to add srclen argument,
9687 swap 1st and 2nd arguments to obey the common convention.
9688 Adjust users accordingly.
9689 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
9691 2012-07-10 Glenn Morris <rgm@gnu.org>
9693 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

9696 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
9697 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
9698 * s/gnu.h (DATA_START): Move definitions to configure.
9700 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
9701 We include usg5-4-common.h, which defines them both.
9703 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
9704 O_RDONLY already includes it).
9706 Stop ns builds setting the EMACSLOADPATH environment variable.
9707 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9708 Now it does not set EMACSLOADPATH, just returns the load-path string.
9709 * nsterm.h: Update accordingly.
9710 * lread.c [HAVE_NS]: Include nsterm.h.
9711 (init_lread) [HAVE_NS]: Use ns_load_path.
9712 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
9714 2012-07-09 Glenn Morris <rgm@gnu.org>
9716 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
9717 since the included bsd-common.h does so.
9719 Stop ns builds setting the EMACSPATH environment variable.
9720 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
9721 (ns_init_paths): Do not set EMACSPATH.
9722 * nsterm.h (ns_exec_path): Add it.
9723 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
9726 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
9728 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
9730 * process.c (wait_reading_process_output): 'waitchannels' was unset
9731 when read_kbd || !NILP (wait_for_cell); fix this.
9733 Add GCC-style 'const' attribute to functions that can use it.
9734 * character.h (char_resolve_modifier_mask):
9735 * keyboard.h (make_ctrl_char):
9736 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
9737 (init_character_once, next_almost_prime, init_fns, init_image)
9738 (flush_pending_output, init_sound):
9739 * mem-limits.h (start_of_data):

9743 Declare the dummy function with ATTRIBUTE_CONST.
9744 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
9745 Add decls with ATTRIBUTE_CONST.
9747 Minor improvements to make_formatted_string.
9748 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
9749 where int is good enough, as vsprintf returns an int.
9750 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
9752 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9754 Use make_formatted_string to avoid double length calculation.
9755 * lisp.h (make_formatted_string): New prototype.

9761 * frame.c (make_terminal_frame, set_term_frame_name)
9762 (x_report_frame_params): Likewise.
9763 * image.c (gs_load): Likewise.
9764 * minibuf.c (get_minibuffer): Likewise.

9779 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9781 Move marker debugging code under MARKER_DEBUG.
9782 * marker.c (MARKER_DEBUG): Move marker debugging code under
9783 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9784 for bootstrap with --enable-checking (~3x slowdown reported
9785 by Juanma Barranquero <lekktu@gmail.com>).
9786 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9788 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9790 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9791 See <http://bugs.gnu.org/11825#29>.
9793 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9795 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9796 has no font, use the frame's font. (Bug#11813)
9797 (display_line): Add commentary about displaying truncation glyphs
9799 (produce_special_glyphs): Move here from term.c.
9801 * term.c (produce_special_glyphs): Move to xdisp.c.
9803 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9806 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9808 * xdisp.c (display_line): Avoid warning about implicit declaration
9811 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9813 * lisp.h: Remove empty conditional.
9815 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9817 * lread.c (load_path_check): Now static.
9819 Fix some minor --with-ns problems found by static checking.
9820 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9821 (x_set_font) [!HAVE_X_WINDOWS]:
9822 * image.c (xpm_load_image) [HAVE_NS]:
9823 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
9824 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
9825 Remove unused local.
9826 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
9827 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
9828 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
9829 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
9830 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
9831 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
9832 Fix pointer signedness problem.
9833 * xfaces.c (FRAME_X_FONT_TABLE):
9834 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
9836 2012-07-07 Glenn Morris <rgm@gnu.org>
9838 * lread.c (load_path_check): New function, split from init_lread.
9839 (init_lread): Reorganize. Motivation:
9840 If EMACSLOADPATH is set, check/warn about that rather than the
9841 defaults, which we are not going to use. Hence we can remove
9842 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9843 Don't warn if site-lisp directories are missing.
9844 If not installed, start from a blank load-path, since
9845 PATH_LOADSEARCH refers to the eventual installation directories.
9847 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9849 Support truncation and continuation glyphs on GUI frames, when
9850 fringes are disabled. (Bug#11832)
9851 * xdisp.c (init_iterator): Get dimensions of truncation and
9852 continuation glyphs even if on GUI frames.
9853 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9854 or both, are absent.
9855 (start_display, move_it_in_display_line_to): Handle the case of a
9856 GUI frame without a fringe to display continuation or truncation
9858 (insert_left_trunc_glyphs): Support GUI frames: make sure
9859 truncation glyphs overwrite enough glyphs from the current line to
9860 have sufficient space in pixels.
9861 (display_line): Support truncation and continuation glyphs on GUI
9862 frames. If some spare pixels are left on the line after inserting
9863 the truncation glyphs, fill that space with a stretch glyph of a
9864 suitably computed width.
9866 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9867 produce_glyphs, to support GUI sessions.
9869 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9871 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9873 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9875 Do not require float-time's arg to fit in time_t (Bug#11825).
9876 This works better on hosts where time_t is unsigned, and where
9877 float-time is applied to the (negative) difference between two times.
9878 * editfns.c (decode_time_components): Last arg is now double *,
9879 not int *, and means to store all the result as a double, without
9880 worrying about whether the seconds part fits in time_t.
9881 All callers changed.
9882 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9883 All callers changed.
9884 (Ffloat_time): Do not fail merely because the specified time falls
9885 outside of time_t range.
9887 2012-07-07 Glenn Morris <rgm@gnu.org>
9889 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9893 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
9895 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
9896 Update dependencies.
9898 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9900 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9902 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9903 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9904 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9905 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9906 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9907 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9909 * xfont.c (compare_font_names): Redo to omit the need for casts.
9911 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9913 * xfns.c (Fx_change_window_property): Doc fix.
9914 * w32fns.c (Fx_change_window_property): Doc fix.
9916 * w32fns.c (Fx_window_property): Accept the same arguments as the
9917 X Windows version. Doc fix.
9918 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9920 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9921 Eli Zaretskii <eliz@gnu.org>
9923 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9924 Windows-specific code from nt/config.nt moved here.
9925 Obsolete settings removed.
9927 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9929 * process.c: Avoid unnecessary calls to gettime.
9930 (wait_reading_process_output): Don't get the time of day
9931 when gobbling data immediately and not waiting, as there's no need
9932 for it in that case. This removes a FIXME.
9934 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9936 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9937 is defined (Bug#11768).
9939 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9941 Fix marker debugging code.
9942 * marker.c (byte_char_debug_check): Do not perform the check
9943 if buffer is not multibyte.
9944 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9945 Call byte_char_debug_check with correct arguments.
9947 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9949 Compile marker debugging code only if ENABLE_CHECKING is defined.
9950 * marker.c (byte_char_debug_check, count_markers):
9951 Use only if ENABLE_CHECKING is defined.
9952 (byte_debug_flag): Remove.
9953 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9954 Always call byte_char_debug_check if ENABLE_CHECKING is defined.

9958 Avoid code repetition in marker-related functions.
9959 * marker.c (attach_marker): New function.

9983 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9984 * window.c (save_window_save): Likewise.
9986 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9988 Do not use Fdelete_overlay in delete_all_overlays
9989 to avoid redundant calls to unchain_overlay.
9990 * buffer.c (drop_overlay): New function.
9991 (delete_all_overlays, Fdelete_overlay): Use it.
9992 * minibuf.c (get_minibuffer): Fix comment.
9994 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9996 Port to OpenBSD 5.1 amd64.
9997 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9998 This is needed for OpenBSD, and should be harmless on all BSD systems.
9999 Also, include <sys/sysctl.h>, as it should be available on all
10000 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10001 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10002 use p_pid member, not kp_proc.pid.
10004 2012-07-06 Glenn Morris <rgm@gnu.org>
10006 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10008 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10010 More xmalloc and related cleanup.

10019 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10021 Omit needless casts involving void * pointers and allocation.
10022 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10023 as the former is more robust if P's type is changed.
10024 Prefer xzalloc to xmalloc + memset 0.
10025 Simplify malloc-or-realloc to realloc.
10026 Don't worry about xmalloc returning a null pointer.
10027 Prefer xstrdup to xmalloc + strcpy.
10028 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10030 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10031 alloca of a constant.
10033 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10035 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10036 hscroll is larger than the line width. Fixes long and futile
10037 looping inside extend_face_to_end_of_line (on a TTY) producing
10038 glyphs that are not needed and thrown away.
10040 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10042 * marker.c (set_marker_restricted_both): Simplify by using
10045 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10047 * editfns.c (region_limit): Simplify by using clip_to_bounds.

10056 followed by gtk_box_set_homogeneous (Bug#11768).
10057 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10058 (update_theme_scrollbar_width, xg_create_scroll_bar):

10061 (is_box_type): New function (Bug#11768).
10062 (xg_tool_item_stale_p): Call is_box_type.
10063 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10064 with default display (Bug#11768).
10066 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10068 * xdisp.c (window_hscroll_limited): New function.
10069 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10070 coordinates when window's hscroll is set to insanely large
10071 values. (Bug#11857)
10073 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10134 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10136 * fileio.c (time_error_value): Check the right error number.
10137 Problem reported by Troels Nielsen in
10138 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10140 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10142 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10143 This should be fixed in a better way; see Eli Zaretskii in
10144 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10145 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10147 * fileio.c (time_error_value): Rename from special_mtime.
10148 The old name's problems were noted by Eli Zaretskii in
10149 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10151 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10152 This variable's comment says Emacs needs at least one GDB-visible
10153 symbol of type enum pvec_type, to work around GDB problems.
10154 The symbol's value doesn't matter.
10156 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10157 that causes compilation to fail on pre-C99 compilers.
10159 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10161 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10162 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10164 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10166 * buffer.c (init_buffer_once): Fix initialization of
10167 headers for buffer_defaults and buffer_local_symbols.

10174 (PSEUDOVECTOR_SIZE_BITS): New constant.
10175 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10176 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10177 change in pvec_type.
10178 (PSEUDOVECTOR_TYPEP): New macro.
10179 (TYPED_PSEUDOVECTORP): Use it.
10180 * fns.c (internal_equal): Adapt code to extract pvectype.
10181 * emacs.c (gdb_pvec_type): Update type.
10182 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10183 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10184 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10185 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10186 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10187 abusing vector->header.next.nbytes.
10188 (live_vector_p): Use PVEC_TYPE.
10189 (mark_object): Adapt code to extract pvectype. Use switch.
10191 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10193 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10194 Tighten new eassert a bit.
10196 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10198 Fix compilation with --enable-gcc-warnings and -O1
10199 optimization level.
10200 * doprnt.c (doprnt): Change type of tem to int, initialize
10201 to avoid compiler warning. Add eassert.
10202 * search.c (simple_search): Initialize match_byte to avoid
10203 compiler warning. Add eassert.
10205 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10207 Avoid weird behavior with large horizontal scrolls.
10208 Without this change, for example, large hscroll values would
10209 mess up Emacs's display on Fedora 15 x86, presumably due to
10210 overflows in int calculations in the display code.
10211 Also, if buffers had long lines, Emacs would freeze.
10212 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10213 (set_window_hscroll): New function, containing the old guts of
10214 Fset_window_hscroll. Return the clipped value.
10215 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10216 This avoids the need to check against PTRDIFF_MAX.
10218 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10220 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10222 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10224 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10226 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10227 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10228 since GCC 4.4.6 issues a bogus warning for them.
10230 Fix bugs in file timestamp newness comparisons.
10231 * fileio.c (Ffile_newer_than_file_p):
10232 * lread.c (Fload): Use full timestamp resolution of files,
10233 not just the 1-second resolution, so that files that are only
10234 slightly newer still count as newer.
10235 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10236 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10238 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10240 * fileio.c: Improve handling of file time marker. (Bug#11852)
10241 (special_mtime): New function.
10242 (Finsert_file_contents, Fverify_visited_file_modtime):
10243 Use it to set special mtime values consistently.
10245 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10247 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10248 marker for non-existing file. (Bug#11852)
10250 2012-07-03 Glenn Morris <rgm@gnu.org>
10252 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10253 and did not make it into globals.h).
10255 2012-07-03 Tom Tromey <tromey@redhat.com>
10257 * window.c (Fset_window_margins, Fset_window_fringes)

10301 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10302 values which aren't power of 2.
10303 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10304 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10307 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10309 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10311 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10313 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10315 * alloc.c (allocate_vector_block): Remove redundant
10316 calls to mallopt if DOUG_LEA_MALLOC is defined.
10317 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10318 avoid calls to mallopt if zero_vector is returned.
10320 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10322 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10323 is enabled, avoid dereferencing NULL current_sblock if
10326 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10328 Cleanup basic buffer management.
10329 * buffer.h (struct buffer): Change layout to use generic vector
10330 marking code. Fix some comments. Change type of 'clip_changed'
10331 to bitfield. Remove unused #ifndef old.
10332 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10333 (GET_OVERLAYS_AT): Fix indentation.

10339 struct buffer. Fix comment.
10340 (mark_overlay): New function.
10341 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10342 Lisp area of struct buffer.
10343 (mark_object): Use it. Adjust marking of misc objects
10344 and related comments.
10346 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10348 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10349 wrapper that is not needed because the wrapped code is a no-op (zero
10350 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10351 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10353 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10355 * alloc.c (mark_buffer): Simplify. Remove prototype.
10356 (mark_object): Add comment. Reorganize marking of vector-like
10357 objects. Use CHECK_LIVE for all vector-like objects except buffers
10358 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10359 Avoid redundant calls to mark_vectorlike for bool vectors.
10361 2012-06-30 Glenn Morris <rgm@gnu.org>
10363 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10365 * epaths.in (PATH_SITELOADSEARCH): New.
10366 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10367 This is rather than relying on --enable-locallisppath elements
10368 having "site-lisp" in their names. (Bug#10208#25, 11658)
10370 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10372 * w32proc.c (sys_select): Accept and ignore one more argument.

10381 * process.c (sys_select):
10382 * msdos.c (sys_select): Accept one more argument and ignore it.
10384 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10385 adapt data types and code to that.
10388 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10389 which clashes with the gnulib function of the same name.
10391 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10393 * font.c (font_style_to_value, font_style_symbolic)
10394 (font_prop_validate_style): Add type checks for values in
10397 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10399 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10402 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10404 * xdisp.c (try_window_id): Undo last change.
10406 * w32.c (getwd): Adjust commentary about startup_dir.
10407 (init_environment): Always call sys_access, even in non-MSVC
10408 builds. Don't chdir to the directory of the Emacs executable.
10409 This undoes code from 1997 which was justified by the need to
10410 "avoid conflicts when removing and renaming directories". But its
10411 downside was that every relative file name was being interpreted
10412 relative to the directory of the Emacs executable, which can never
10413 be TRT. In particular, it broke sys_access when called with
10414 relative file names.
10415 (sys_access): Map GetLastError to errno.
10417 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

10423 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'

10454 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10455 overflow when requested scroll falls outside ptrdiff_t range.

10459 * window.h (struct window): Change type of 'hscroll',
10460 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10461 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10462 Adjust users accordingly.
10463 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10464 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10465 from EMACS_INT to ptrdiff_t.

10541 * alloc.c (allocate_string): Omit intervals initialization.
10542 * alloc.c (make_uninit_multibyte_string): Initialize intervals

10567 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
10568 when building with Clang.

10599 * alloc.c: Remove build_string.
10600 * lisp.h: Define build_string as static inline. This provides

10602 function is called with compile-time constant argument.
10603 * image.c (imagemagick_error): Convert to build_string.

10607 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10609 Use sprintf return value instead of invoking strlen on result.
10610 In the old days this wasn't portable, since some sprintf
10611 implementations returned char *. But they died out years ago and
10612 Emacs already assumes sprintf returns int.
10613 Similarly for float_to_string.
10614 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10621 * xfns.c (syms_of_xfns):
10622 Use sprintf or float_to_string result to avoid need to call strlen.
10623 * data.c (Fnumber_to_string):
10624 Use make_unibyte_string, since the string must be ASCII.
10625 * lisp.h, print.c (float_to_string): Now returns int length.
10626 * term.c (produce_glyphless_glyph):
10627 Use sprintf result rather than recomputing it.
10629 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10630 * Makefile.in (ALL_CFLAGS):
10631 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

10636 * dispextern.h (xstrcasecmp): Define to library function
10637 strcasecmp if available.

10656 sprintf already null-terminates its output.
10658 * xfns.c (x_window): Remove redundant cast.
10660 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10662 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10663 `const char *' to `char *' to avoid compiler warning.
10665 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10667 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10668 instead of truncating it to 63 (admittedly a generous limit).
10670 * process.c: Fix spelling and caps in comments.
10672 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10674 * emacs.c (setpgrp): Remove definition, unused.

10725 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

10728 * keyboard.c (kbd_buffer_get_event):
10729 * process.c (Faccept_process_output):
10730 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10731 This improves on the previous patch, which introduced a bug
10732 when time_t is unsigned and as wide as intmax_t.
10733 See <http://bugs.gnu.org/9000#51>.
10735 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10764 language ID in the event parameters.
10766 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10767 event.code, not the obscure "character set ID".
10769 2012-06-23 Chong Yidong <cyd@gnu.org>

10800 Support higher-resolution time stamps (Bug#9000).
10801 The time stamps are only nanosecond-resolution at the C level,
10802 since that's the best that any real-world system supports now.
10803 But they are picosecond-resolution at the Lisp level, as that's
10804 easy, and leaves room for future OS improvements.
10806 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10809 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10810 Don't get current time unless it's needed.
10812 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10813 now provides it if it's absent.
10814 (start_atimer): Port to higher-res time stamps.
10815 Check for time stamp overflow. Don't get current time more
10816 often than is needed.
10818 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10819 Include systime.h, not time.h.
10820 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.

10823 (Ffile-attributes): File times now have higher resolution.
10825 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10826 (struct image): Timestamp now has higher resolution.
10828 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10829 has at least microseconds now. All uses removed.
10830 (update_frame, update_single_window, update_window, update_frame_1)
10831 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10832 (duration_to_sec_usec): Remove; no longer needed.

10840 (decode_time_components, lisp_seconds_argument): New functions.
10841 (make_time): Now static.
10842 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10843 Report an error if the time is invalid, rather than having the caller
10846 * fileio.c: Include <stat-time.h>
10847 (Fcopy_file): Copy higher-resolution time stamps.
10848 Prefer to set the time stamp via a file descriptor if that works.
10849 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10850 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10851 (Fvisited_file_modtime, Fset_visited_file_modtime):
10852 Support higher-resolution time stamps.
10854 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10856 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10858 * image.c (prepare_image_for_display, clear_image_cache)
10859 (lookup_image): Port to higer-resolution time stamps.
10861 * keyboard.c (start_polling, bind_polling_period):
10862 Check for time stamp overflow.
10863 (read_char, kbd_buffer_get_event, timer_start_idle)
10864 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10865 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10866 Port to higher-resolution time stamps. Do not assume time_t is signed.
10867 (decode_timer): New function. Timers are now vectors of length 9,
10868 not 8, to accommodate the picosecond component.
10869 (timer_check_2): Use it.
10871 * nsterm.m (select_timeout, timeval_subtract): Remove.
10872 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10873 as they're a bit more accurate and handle overflow better.
10874 (ns_select): Change prototype to be compatible with pselect.
10875 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10876 * nsterm.h (ns_select): Adjust prototype.
10878 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10879 us-resolution time stamps.
10880 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10882 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10884 * lisp.h (time_overflow): New decl.

10886 to accommodate larger waits.
10888 * process.h (struct Lisp_Process.read_output_delay):
10889 Now counts nanoseconds, not microseconds.
10890 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10892 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10893 (wait_reading_process_output):
10894 Port to ns-resolution time stamps.
10895 (Faccept_process_output, wait_reading_process_output):
10896 Check for time stamp overflow. Do not assume time_t is signed.
10897 (select_wrapper): Remove; we now use pselect.
10898 (Fprocess_attributes): Now generates ns-resolution time stamps.
10900 * sysdep.c: Include utimens.h. Don't include utime.h
10901 or worry about struct utimbuf; gnulib does that for us now.
10902 (gettimeofday): Remove; gnulib provides a substitute.
10903 (make_timeval): New function.
10904 (set_file_times): Now sets ns-resolution time stamps.
10905 New arg FD; all uses changed.
10906 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10907 (system_process_attributes):
10908 Now returns ns-resolution time stamp. All uses changed.
10909 Check for time stamp overflow.
10911 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10912 provides a substitute now.
10914 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10915 since it guarantees struct timespec.
10916 (EMACS_TIME): Now struct timespec, so that we can support
10917 ns-resolution time stamps.
10918 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10919 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10920 (EMACS_USECS): Remove.
10921 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10922 so multiply the arg by 1000 before storing it.
10923 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10925 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

10932 (make_timeval, make_lisp_time, decode_time_components): New decls.
10933 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10934 that it mishandled time_t overflow. You can't compare by subtracting!
10935 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10936 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10938 * term.c: Include <sys/time.h>.
10939 (timeval_to_Time): New function, for proper overflow wraparound.
10940 (term_mouse_position, term_mouse_click): Use it.
10942 * undo.c (record_first_change): Support higher-resolution time stamps
10943 in the undo buffer.
10944 (Fprimitive_undo): Use them when restoring time stamps.
10946 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10947 (w32_get_internal_run_time):
10948 Port to higher-resolution Emacs time stamps.
10949 (ltime): Now accepts single 64-bit integer, as that's more convenient
10952 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10954 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10955 for compatibility with pselect. Support ns-resolution time stamps.
10957 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10959 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10960 Check for time stamp overflow, and support ns-resolution time stamps.
10962 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10963 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10964 (timeval_subtract): Remove; no longer needed.
10965 (XTflash, XTring_bell, x_wait_for_event):
10966 Port to ns-resolution time stamps. Don't assume time_t is signed.
10968 2012-06-22 Chong Yidong <cyd@gnu.org>

10972 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10974 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10975 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10976 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10977 staticidx goes up to 1597 out of 1600 = 0x640.)
10979 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10981 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10982 Otherwise, the umask might be mistakenly 0 while handling input signals.
10984 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10986 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10992 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10993 access to `contents' member of Lisp_Vector objects with AREF and ASET
10996 2012-06-19 Chong Yidong <cyd@gnu.org>
10998 * frame.c (delete_frame): When selecting a frame on a different
10999 text terminal, do not alter the terminal's top-frame.
11001 * xdisp.c (format_mode_line_unwind_data): Record the target
11002 frame's selected window and its terminal's top-frame.
11003 (unwind_format_mode_line): Restore them.
11004 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11006 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11007 since tty frames can be explicitly named.
11008 (prepare_menu_bars): Likewise.
11010 * term.c (Ftty_top_frame): New function.
11012 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11014 Port byte-code-meter to modern targets.
11015 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11016 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11017 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11018 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
11019 (METER_1, METER_2): Simplify.
11021 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

11025 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11027 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11028 gets killed during executing of this function (Bug#11665).
11029 Try to always return Qt when the buffer has been actually killed.
11030 (Vkill_buffer_query_functions): In doc-string say that functions
11031 run by this hook should not change the current buffer.
11033 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11035 Fix recently-introduced process.c problems found by static checking.

11053 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
11055 * lisp.h (eassert): Assume C89 or later.
11056 This removes the need for CHECK.
11057 (CHECK): Remove. Its comments about always evaluating its
11058 argument were confusing, as 'eassert' typically does not evaluate
11061 * coding.c (produce_chars): Use ptrdiff_t, not int.
11063 * xterm.c (x_draw_underwave): Check for integer overflow.
11064 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

11250 as the union type is for debugging, not for production.
11251 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
11252 Use an inline function on all platforms when using the union type,
11253 since this is simpler and 'static inline' can be used portably

11370 adjust comment accordingly.
11371 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
11372 to denote vector blocks. Adjust users (live_vector_p,

11395 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11397 * doprnt.c (doprnt): Truncate multibyte char correctly.
11398 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11399 would mishandle a string argument "Xc" if X was a multibyte
11400 character of length 2: it would truncate after X's first byte
11401 rather than including all of X.
11403 2012-06-06 Chong Yidong <cyd@gnu.org>
11405 * buffer.c (word_wrap): Doc fix.

11452 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11454 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11455 Convert pctcpu and pctmem to Lisp float properly.
11456 Let the compiler fold better, as 100.0/0x8000 is exact.
11458 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11460 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11463 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

11467 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11469 For a 'struct window', replace some Lisp_Object fields to
11470 bitfields where appropriate, remove unused fields.
11471 * window.h (struct window): Remove unused 'last_mark_x' and
11472 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11473 change its type from Lisp_Object to bitfield.
11474 Change type of 'force_start', 'optional_new_start',
11475 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11476 fields from Lisp_Object to bitfield. Adjust users accordingly.
11478 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11480 Pacify gcc -Wdouble-precision when using Xaw.
11481 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11482 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11483 Use 'float' consistently, rather than 'float' in most places
11484 and 'double' in a couple of places.
11486 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11488 * xdisp.c (handle_stop): Detect whether we have overlay strings
11489 loaded by testing it->current.overlay_string_index to be
11490 non-negative, instead of checking whether n_overlay_strings is
11491 positive. (Bug#11587)
11493 2012-05-31 Chong Yidong <cyd@gnu.org>
11495 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11499 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11501 * search.c (search_buffer): Remove calls to
11502 r_alloc_inhibit_buffer_relocation, as it is now called by
11503 maybe_unify_char, which was the cause of relocation of buffer text
11506 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11508 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11509 for the duration of call to load_charset, to avoid problems with
11510 callers of maybe_unify_char that access buffer text through C
11513 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11514 decrement the inhibition flag, instead of just setting or
11517 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11519 Remove obsolete '#define static' cruft.
11520 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11521 This #undef was "temporary" in 2000; it is no longer needed
11522 now that '#define static' has gone away.
11523 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11524 (gray_bitmap_bits): Remove; no longer needed.
11525 All uses replaced with definiens.
11526 * xterm.c: Include "bitmaps/gray.xbm".
11528 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>

11531 The following changes affect the code only when profiling.
11532 * dispnew.c (__executable_start): Rename from safe_bcopy.
11533 Define only on platforms that need it.
11534 * emacs.c: Include <sys/gmon.h> when profiling.
11535 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11536 (__executable_start): Remove decl, since lisp.h does it now.
11537 (safe_bcopy): Remove decl; no longer has that name.
11538 (main): Coalesce #if into single bit of code, for simplicity.
11539 Cast pointers to uintptr_t, since standard libraries want integers
11541 * lisp.h (__executable_start): New decl.
11543 2012-05-31 Glenn Morris <rgm@gnu.org>
11545 * image.c (Fimagemagick_types): Doc fix.

11568 Do not create empty overlays with the evaporate property (Bug#9642).
11569 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11570 Bug#9642, but explicitly check that the buffer the overlay would
11571 be moved to is live and rearrange lines to make sure that errors
11572 will not put the overlay in an inconsistent state.
11573 (Fdelete_overlay): Cosmetics.
11575 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11577 * w32term.c (my_bring_window_to_top): New function.
11578 (x_raise_frame): Use handle returned by DeferWindowPos, which
11579 could be different from the original one.

11589 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11591 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11592 This avoids undefined behavior that might cause the eassert
11593 to not catch an out-of-range value.
11595 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11597 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

11611 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11612 Only r_alloc_inhibit_buffer_relocation needed to be added;
11613 the others were already declared.
11615 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11616 before checking whether it's out of range. Put the check inside
11618 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11620 2012-05-27 Ken Brown <kbrown@cornell.edu>

11632 they are now on lisp.h.
11634 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11636 * search.c (search_buffer): Use it to inhibit relocation of buffer
11637 text while re_search_2 is doing its job, because re_search_2 is
11638 passed C pointers to buffer text. (Bug#11519)
11640 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11641 Update value to 24.
11643 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11644 state after an additional call to move_it_in_display_line_to, keep
11645 the values of it->max_ascent and it->max_descent found for the
11647 (pos_visible_p): Revert the comparison against bottom_y to what it
11648 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11651 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11653 Fix coding-related core dumps with gcc -ftrapv.
11654 The code was computing A - B, where A and B are pointers, and B is
11655 random garbage. This can lead to core dumps on platforms that
11656 have special pointer registers, and it also leads to core dumps on
11657 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11658 A - B only when B is initialized properly.
11659 * coding.c (coding_set_source, coding_set_destination): Return void.
11660 (coding_change_source, coding_change_destinations): New functions,
11661 with the old behaviors of coding_set_source and coding_set_destination.

11672 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11674 * w32console.c: Include window.h.
11675 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11677 (initialize_w32_display): Initialize mouse-highlight data.
11679 * w32inevt.c: Include termchar.h and window.h.
11680 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11681 moves, call note_mouse_highlight. If help_echo changed, call
11682 gen_help_event to produce help-echo message in the echo area.
11683 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11686 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11688 * lread.c (read1): Simplify slightly to avoid an overflow warning
11689 with GCC 4.7.0 on x86-64.
11691 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11693 * bidi.c (bidi_mirror_char): Revert last change: an int is
11694 definitely wide enough here.

11706 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
11708 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11710 Use int, not EMACS_INT, where int is wide enough.
11711 (inhibit_garbage_collection, Fgarbage_collect):

11725 (overlay_touches_p, struct sortvec, record_overlay_string)
11726 (overlay_strings, recenter_overlay_lists)
11727 (adjust_overlays_for_insert, adjust_overlays_for_delete)

11732 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11733 (validate_region): Omit unnecessary test for b <= e,
11734 since that's guaranteed by the previous test.

11736 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11737 (report_overlay_modification):
11738 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11739 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11740 Omit pointer cast, which isn't needed anyway, and doesn't work
11741 after the EMACS_INT -> ptrdiff_t change.
11742 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11743 * buffer.h: Adjust decls to match defn changes elsewhere.
11744 (struct buffer_text, struct buffer):

11747 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11748 not int, to avoid needless 32-bit limit on 64-bit hosts.
11749 (exec_byte_code): Use tighter memory-full test, one that checks
11750 for alloca overflow. Don't compute the address of the object just
11751 before an array, as that's not portable. Use EMACS_INT, not
11752 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11753 * callint.c (Fcall_interactively):
11754 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11755 * callproc.c (call_process_kill, Fcall_process):

11767 (casify_object): Avoid integer overflow when overallocating buffer.
11768 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

11771 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11772 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

11776 For CCL_MapSingle, check that content and value are in int range.
11777 (ccl_driver, Fregister_code_conversion_map):
11778 Check that Vcode_version_map_vector is a vector.
11779 (resolve_symbol_ccl_program): Check that vector header is in range.
11780 Always copy the vector, so that we can check its contents reliably
11781 now rather than having to recheck each instruction as it's being
11782 executed. Check that vector words fit in 'int'.
11783 (ccl_get_compiled_code, Fregister_ccl_program)
11784 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11785 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

11787 contents are in range.
11788 (Fccl_execute_on_string): Check that status is in range.
11789 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11790 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11791 Accept and return EMACS_INT, not int, because callers can pass values

11798 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11810 (Fdefine_charset_internal): Check ranges here, more carefully.
11811 Don't rely on undefined behavior with signed left shift overflow.
11812 Don't assume unsigned int fits into fixnum, or that fixnum fits
11813 into unsigned int. Don't require max_code to be a valid fixnum;
11814 that's not true for gb10830 4-byte on a 32-bit host. Allow
11815 invalid_code to be a cons, for the same reason. Require code_offset
11816 to be a character. Avoid int overflow if max_char is close
11818 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11819 this is intended anyway and avoids some undefined behavior.
11820 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11821 INDEX_TO_CODE_POINT, as that's what it expects.
11822 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11823 * charset.h (DECODE_CHAR): Return int, not unsigned;
11824 this is what was intended anyway, and it avoids undefined behavior.

11826 integer-overflow issues.
11827 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11828 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11829 where the argument is EMACS_INT, and this behavior is not intended.
11830 * chartab.c (Fmake_char_table, Fset_char_table_range)
11831 (uniprop_get_decoder, uniprop_get_encoder):
11832 Don't assume fixnum fits in int.
11833 * cmds.c (move_point): New function, that does the gist of
11834 Fforward_char and Fbackward_char, but does so while checking
11835 for integer overflow more accurately.
11836 (Fforward_char, Fbackward_char): Use it.
11837 (Fforward_line, Fend_of_line, internal_self_insert)
11838 (internal_self_insert):
11839 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12445 (get_next_display_element, next_element_from_display_vector):
12446 Use int, not EMACS_INT, when int is wide enough.

12486 * xterm.c (x_x_to_emacs_modifiers):
12487 Don't assume EMACS_INT overflows nicely into int.
12488 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12489 may come from Lisp.
12490 (handle_one_xevent): NATNUMP can eval its arg twice.
12491 (x_connection_closed):

12498 2012-05-25 Glenn Morris <rgm@gnu.org>
12500 * lisp.mk (lisp): Update for more files being compiled now.
12502 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12504 * lread.c: Remove `read_pure' which makes no difference.
12505 (read_pure): Remove var.
12506 (unreadpure): Remove function.
12507 (readevalloop): Don't call read_list with -1 flag.
12508 (read1, read_vector): Don't test read_pure any more.
12509 (read_list): Simplify.
12511 * fileio.c, character.h: Minor style tweaks.

12517 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
12519 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
12520 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12522 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12525 This directory predates autoconf and is no longer needed nowadays.
12526 Move its few remaining bits of functionality to where they're needed.
12527 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12528 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12529 * m/template.h: Remove.
12530 * Makefile.in (M_FILE): Remove. All uses removed.
12531 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12532 * lisp.h (USE_LSB_TAG):
12533 * mem-limits.h (EXCEEDS_LISP_PTR):
12534 Use VAL_MAX, not VALBITS, in #if.
12535 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12536 (EMACS_UINT): Define unconditionally now.
12537 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12538 (BITS_PER_EMACS_INT): New constants, replacing
12539 what used to be in config.h, but not useful in #if.
12540 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12541 define them any more.
12542 (VAL_MAX): New macro.
12544 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12545 BITS_PER_EMACS_INT, in #if.
12546 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12547 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12548 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12549 * s/ms-w32.h (DATA_START):
12550 Move here from removed file m/intel386.h.
12551 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12552 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12554 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12556 Assume C89 or later.
12557 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12558 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12560 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

12566 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12567 * xterm.c (input_signal_count): Assume volatile works.
12569 2012-05-21 Ken Brown <kbrown@cornell.edu>
12571 * xgselect.c (xg_select): Fix first argument in call to 'select'
12574 2012-05-20 Ken Brown <kbrown@cornell.edu>
12576 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12577 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12579 2012-05-19 Ken Brown <kbrown@cornell.edu>
12581 * xfns.c (x_in_use): Remove `static' qualifier.
12582 * xterm.h (x_in_use): Declare.
12583 * xgselect.c: Include xterm.h.
12584 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12585 and `display_arg' (bug#9754).
12587 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12589 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12591 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12592 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12594 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12596 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12598 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12599 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12601 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12602 reference to image_cache->refcount.
12603 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12605 2012-05-17 Juri Linkov <juri@jurta.org>
12607 * search.c (Fword_search_regexp, Fword_search_backward)
12608 (Fword_search_forward, Fword_search_backward_lax)
12609 (Fword_search_forward_lax): Move functions to isearch.el
12610 (bug#10145, bug#11381).
12612 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12614 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12616 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12618 * lread.c (init_obarray): Declare Qt and Qnil as special.
12620 2012-05-14 Glenn Morris <rgm@gnu.org>
12622 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12623 Put "libexec" before "bin", for the sake of init_callproc_1.
12625 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12627 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12629 * unexaix.c: Port to more-recent AIX compilers.
12630 (report_error, report_error_1, make_hdr, copy_sym)
12631 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12632 Make arguments const char *, not char *, to avoid violations of C
12633 standard and to fix some AIX warnings reported by Gilles Pion.
12635 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12637 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12638 already have overlays loaded.
12639 (handle_single_display_spec): Before returning without displaying
12640 fringe bitmap, synchronize the bidi iterator with the main display
12641 iterator, by calling iterate_out_of_display_property.
12642 (iterate_out_of_display_property): Detect buffer iteration by
12643 testing that it->string is a Lisp string.
12644 (get_next_display_element): When the current object is exhausted,
12645 and there's something on it->stack, call set_iterator_to_next to
12646 proceed with what's on the stack, instead of returning zero.
12647 (set_iterator_to_next): If called at the end of a Lisp string,
12648 proceed to consider_string_end without incrementing string
12649 position. Don't increment display vector index past the end of
12650 the display vector. (Bug#11417)
12651 (pos_visible_p): Don't report a position visible when move_it_to
12652 stopped at the last line of window, which happens to be scanned
12653 backwards by the bidi iteration. (Bug#11464)
12655 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12657 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12658 and right-margin display specs even if the spec is invalid or we
12659 are on a TTY, and thus unable to display on the fringes.
12660 That's because the text with the property will not be displayed anyway,
12661 so we need to signal to the caller that this is a "replacing"
12662 display spec. This fixes display when the spec is invalid or we
12665 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12667 * unexaix.c (make_hdr): Fix typo in prototype.
12668 This bug broke the build on AIX. Problem reported by Gilles Pion.
12670 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12672 * keyboard.c (kbd_buffer_get_event): Read special events also in
12673 batch mode. (Bug#11415)
12675 2012-05-12 Glenn Morris <rgm@gnu.org>
12677 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12679 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12681 * lisp.mk (lisp): Add newcomment.elc.
12683 2012-05-12 Glenn Morris <rgm@gnu.org>
12685 * Makefile.in (MKDIR_P): New, set by configure.
12686 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12688 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12690 Remove unused function hourglass_started.
12691 * dispextern.h (hourglass_started):
12692 * w32fns.c (hourglass_started):
12693 * xdisp.c (hourglass_started): Remove.
12695 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12697 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12698 Update dependencies.
12700 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12702 * xgselect.c (xg_select): Put maxfds+1 into a var.
12703 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12705 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12707 2012-05-10 Dave Abrahams <dave@boostpro.com>
12709 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12710 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12712 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12714 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12715 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12716 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12717 Initialize xd_registered_buses.
12719 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12721 Untag more efficiently if USE_LSB_TAG.
12722 This is based on a proposal by YAMAMOTO Mitsuharu in
12723 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12724 For an admittedly artificial (nth 8000 longlist) benchmark on
12725 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12726 Emacs's overall text size by 1%.
12727 * lisp.h (XUNTAG): New macro.
12728 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12729 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12730 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12731 * eval.c (Fautoload):
12732 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12733 * frame.h (XFRAME): Use XUNTAG.
12735 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12736 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12737 Remove unportable assumptions about print widths of types like
12739 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12740 intptr_t when converting between pointer and integer, to avoid GCC
12741 warnings about wrong width.
12743 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12745 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12746 stack for each reader_thread, instead of defaulting to 8MB
12747 determined by the linker. This avoids failures in creating
12748 subprocesses on Windows 7, see the discussion in this thread:
12749 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12751 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12753 Fix up display of the *Minibuf-0* buffer in the mini window.
12754 * keyboard.c (read_char): Don't clear the echo area if there's no
12756 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12757 contents of *Minibuf-0*) if there's no message displayed in its stead.
12759 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12761 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12764 2012-05-06 Chong Yidong <cyd@gnu.org>
12766 * lisp.mk (lisp): Update.
12768 2012-05-05 Jim Meyering <meyering@redhat.com>
12770 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12772 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12774 * data.c (PUT_ERROR): New macro.
12775 (syms_of_data): Use it. Add new error type `user-error'.
12776 * undo.c (user_error): New function.
12777 (Fprimitive_undo): Use it.
12778 * print.c (print_error_message): Adjust print style for `user-error'.
12779 * keyboard.c (user_error): New function.
12780 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12782 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12784 Do not limit current-time-string to years 1000..9999.
12785 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12786 (Fcurrent_time_string): Support any year that is supported by the
12787 underlying localtime representation. Don't use asctime, as it
12788 has undefined behavior for years outside the range -999..9999.
12790 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12792 Fix race conditions involving setenv, gmtime, localtime, asctime.
12793 Without this fix, interrupts could mess up code that uses these
12794 nonreentrant functions, since setting TZ invalidates existing
12795 tm_zone or tzname values, and since most of these functions return
12796 pointers to static storage.
12797 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12798 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12799 Grow the critical sections to include not just invoking
12800 localtime/gmtime, but also accessing these functions' results
12801 including their tm_zone values if any, and any related TZ setting.
12802 (format_time_string): Last arg is now struct tm *, not struct tm **,
12803 so that the struct tm is saved in the critical section.
12804 All callers changed. Simplify allocation of initial buffer, partly
12805 motivated by the fact that memory allocation needs to be outside
12806 the critical section.
12808 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12810 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12811 with RESET_INTERVAL.
12813 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12814 Remove duplicated buffer name initialization.
12816 2012-05-02 Jim Meyering <jim@meyering.net>
12818 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12820 * xfns.c (x_window): Use xstrdup (Bug#11375).
12822 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12824 * xdisp.c (pos_visible_p): If already at a newline from the
12825 display string before the 'while' loop, don't walk back the glyphs
12826 from it3.glyph_row. Solves assertion violation when the display
12827 string begins with a newline (egg.el). (Bug#11367)
12829 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>

12837 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12838 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12839 All were removed before 23.1.
12841 * dispnew.c: Remove HAVE_LIBNCURSES test;
12842 it is always true on relevant platforms.
12844 * Makefile.in (LD_SWITCH_X_SITE_RPATH):

12857 Do not avoid creating empty evaporating overlays (Bug#9642).
12858 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12859 That is, do not delete an evaporating overlay if it becomes
12860 empty after its bounds are adjusted to fit within its buffer.
12861 This fix caused other problems, and I'm reverting it until we get
12862 to the bottom of them.
12864 2012-04-27 Chong Yidong <cyd@gnu.org>
12866 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12868 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12870 * xdisp.c (pos_visible_p): If the window start position is beyond
12871 ZV, start the display from buffer beginning. Prevents assertion
12872 violation in init_iterator when the minibuffer window is scrolled
12873 via the scroll bar.
12875 * window.c (window_scroll_pixel_based): Likewise.
12877 2012-04-27 Chong Yidong <cyd@gnu.org>

12884 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12886 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12888 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12889 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12891 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12893 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12894 display element, check also the underlying string or buffer
12895 character. (Bug#11341)
12897 * w32menu.c: Include w32heap.h.
12898 (add_menu_item): If the call to AppendMenuW (via
12899 unicode_append_menu) fails, disable Unicode menus only if we are
12900 running on Windows 9X/Me.
12902 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12904 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12905 (xgetint): Add missing shift for LSB tags.
12907 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12909 * keyboard.c (read_char): Don't wipe echo area for select window
12910 events: These might get delayed via `mouse-autoselect-window'

12915 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12916 manipulation of :loaded-from data.
12918 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12920 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12921 now a cons (bug#11311).
12923 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12925 Do not create empty overlays with the evaporate property (Bug#9642).
12926 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12927 if it becomes empty after its bounds are adjusted to fit within
12928 its buffer. Without this fix, in a nonempty buffer (let ((o
12929 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12930 yields an empty overlay that has the evaporate property, which is
12931 not supposed to happen.

13049 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13050 Use Emacs indenting style more consistently. Avoid some casts.

13065 It is never used otherwise.
13067 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13069 * print.c (print_preprocess): Only check print_depth if print-circle

13264 * minibuf.c (Fread_variable): Callers changed.
13266 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13268 * xdisp.c (set_cursor_from_row): If the display string appears in
13269 the buffer at position that is closer to point than the position
13270 after the display string, display the cursor on the first glyph of
13271 the display string. Fixes cursor display when a 'display' text
13272 property immediately follows invisible text. (Bug#11094)
13274 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13276 composite.c: use 'double' consistently
13277 * composite.c (get_composition_id): Use 'double' consistently
13278 instead of converting 'float' to 'double' and vice versa; this is
13279 easier to understand and avoids a GCC warning.
13281 2012-04-09 Glenn Morris <rgm@gnu.org>
13283 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13284 preparation for dumping it with emacs. (Bug#4789)
13285 (leimdir): New variable.
13286 ($(leimdir)/leim-list.el): New rule.
13287 (emacs$(EXEEXT)): Depend on leim-list.el.

13305 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
13306 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13307 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13308 objects, as mark_maybe_pointer will catch them otherwise.
13309 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13310 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

13317 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13319 Support building on MS-Windows with libxml2.
13321 * makefile.w32-in (OBJ2): Add xml.$(O).
13322 (GLOBAL_SOURCES): Add xml.c.
13323 ($(BLD)/xml.$(O)): New dependency list.
13325 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.

13328 [!WINDOWSNT]: New macros.
13329 (init_libxml2_functions, libxml2_loaded_p): New functions.
13330 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13331 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13332 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13333 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13335 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13336 Call init_libxml2_functions before calling libxml2 functions.
13337 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13339 * emacs.c: Don't include libxml/parser.h.
13340 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13341 xmlCleanupParser directly.
13343 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13345 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13347 * indent.c (Fvertical_motion): If there is a display string at
13348 point, use it.vpos to compute how many lines to backtrack after
13349 move_it_to point. (Bug#11133)
13351 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13353 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13354 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13355 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13356 macros related to unification of CJK characters. For the details,
13357 see the discussion following the message here:
13358 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13360 2012-04-04 Chong Yidong <cyd@gnu.org>
13362 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13364 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13366 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13367 instead of alloca. (Bug#11138)
13369 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13371 * w32menu.c (is_simple_dialog): Properly check lisp types.
13374 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13376 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13377 position we get to after a call to move_it_to fails the
13378 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13379 only if we wind up in a string from display property. (Bug#11063)
13381 * window.c (Fdelete_other_windows_internal): Invalidate the row
13382 and column information about mouse highlight, so that redisplay
13383 restores it after reallocating the glyph matrices. (Bug#7464)
13385 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13386 string comes from a `display' text property, use the buffer
13387 position of that property as if we actually saw that position in
13389 (move_it_by_lines): Remove the assertion that
13390 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13391 violated when there's a before-string at the beginning of a line.
13394 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13396 * xdisp.c (append_space_for_newline): If the default face was
13397 remapped, use the remapped face for the appended newline.
13398 (extend_face_to_end_of_line): Use the remapped default face for
13399 extending the face to the end of the line.
13400 (display_line): Call extend_face_to_end_of_line when the default
13401 face was remapped. (Bug#11068)
13403 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13405 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13407 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13409 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13411 2012-03-27 Glenn Morris <rgm@gnu.org>
13413 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13416 2012-03-26 Kenichi Handa <handa@m17n.org>
13418 * dispextern.h (struct glyph): Fix previous change. Change the
13419 bit length of glyphless.ch to 25 (Bug#11082).
13421 2012-03-26 Chong Yidong <cyd@gnu.org>
13423 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13424 (command_loop_1): Use it; inhibit selection update for
13425 handle-select-window too (Bug#8996).
13427 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13429 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13431 2012-03-25 Kenichi Handa <handa@m17n.org>
13433 * dispextern.h (struct glyph): Change the bit length of
13434 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13436 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13438 * s/ms-w32.h (tzname): Include time.h before redirecting to
13439 _tzname. Fixes the MSVC build. (Bug#9960)
13441 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13443 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13446 * xterm.c (XTread_socket): Only modify handling_signal if
13447 !SYNC_INPUT. (Bug#11080)
13449 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13451 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13452 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13453 when fetching a multibyte character consumes more bytes than
13454 CHAR_BYTES returns, due to unification of CJK characters in
13455 string_char. (Bug#11073)
13457 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13459 * process.c (wait_reading_process_output): Handle pty disconnect
13460 by refraining from sending oneself a SIGCHLD (bug#10933).

13467 Mark string as coming from a prefix property.
13468 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13469 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13471 2012-03-21 Chong Yidong <cyd@gnu.org>
13473 * xfaces.c (Vface_remapping_alist): Doc fix.
13475 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13477 * w32proc.c (Fw32_set_console_codepage)
13478 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13481 2012-03-20 Chong Yidong <cyd@gnu.org>
13483 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13484 to reflect default non-nil value of redisplay-dont-pause.
13486 2012-03-19 Kenichi Handa <handa@m17n.org>
13488 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13489 it fit in a valid range (Bug#11003).
13491 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13493 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13494 that is not from display property, accept the row as a "cursor
13495 row" if one of the string's character has a non-nil `cursor'
13496 property. Fixes cursor positioning when there are newlines in
13497 overlay strings, e.g. in icomplete.el. (Bug#11035)
13499 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13501 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13503 2012-03-12 Chong Yidong <cyd@gnu.org>
13505 * eval.c (inhibit_lisp_code): Rename from
13506 inhibit_window_configuration_change_hook; move from window.c.
13508 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13509 * window.c (run_window_configuration_change_hook)
13510 (syms_of_window): Callers changed.
13512 2012-03-11 Chong Yidong <cyd@gnu.org>

13529 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13530 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13533 2012-03-03 Glenn Morris <rgm@gnu.org>
13535 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13537 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13539 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13540 position past the first glyph_row that ends at ZV. (Bug#10902)
13541 (redisplay_window, next_element_from_string): Fix typos in
13543 (redisplay_window): Pass to move_it_vertically the margin in
13544 pixels, not in screen lines.
13546 2012-03-02 Glenn Morris <rgm@gnu.org>
13548 * buffer.c (buffer-list-update-hook): Doc fix.
13550 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13552 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13553 push_it before setting up the iterator for the first overlay
13554 string, even if we have an empty string loaded.
13555 (next_overlay_string): If there's an empty string on the iterator
13556 stack, pop the stack. (Bug#10903)
13558 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13560 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13561 Suggested by Stefan Monnier in
13562 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13563 * alloc.c (widen_to_Lisp_Object): New static function.
13564 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13565 and widening them to Lisp_Objects. This would work even if
13566 USE_LSB_TAG is defined and wide integers are used, which might
13567 happen in a future version of Emacs.
13569 2012-02-25 Chong Yidong <cyd@gnu.org>
13571 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13574 * xselect.c (Fx_selection_exists_p): Doc fix.

13576 before saving to clipboard manager.
13578 2012-02-24 Chong Yidong <cyd@gnu.org>
13580 * keyboard.c (process_special_events): Handle all X selection
13581 requests in kbd_buffer, not just the next one (Bug#8869).
13583 2012-02-23 Chong Yidong <cyd@gnu.org>
13585 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13586 call when setting menu-bar-lines and tool-bar-lines parameters.
13587 (unwind_create_frame_1): New helper function.
13589 * window.c (inhibit_window_configuration_change_hook): New var.

13608 when computing $valmask.
13610 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13611 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13612 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13613 It's useless in that case, and it can cause problems on hosts
13614 that allocate halves of EMACS_INT values separately.
13615 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13616 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13617 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13618 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13619 it avoids undefined behavior on hosts where shifting right by more
13620 than the word width has undefined behavior.
13622 2012-02-19 Chong Yidong <cyd@gnu.org>
13624 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13625 (Funhandled_file_name_directory, Ffile_name_as_directory)
13626 (Fdirectory_file_name, Fexpand_file_name)
13627 (Fsubstitute_in_file_name): Protect against invalid file handler
13628 return values (Bug#10845).

13642 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13644 2012-02-15 Chong Yidong <cyd@gnu.org>
13646 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13647 marked as special. Also, starting docstrings with * is obsolete.

13662 2012-02-12 Chong Yidong <cyd@gnu.org>
13664 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13665 as that creates a dangerous corner case.
13667 * window.c (Fdelete_window_internal): Invalidate the mouse
13668 highlight (Bug#9904).
13670 2012-02-12 Glenn Morris <rgm@gnu.org>
13672 * xselect.c (Fx_own_selection_internal)
13673 (Fx_get_selection_internal, Fx_disown_selection_internal)
13674 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
13675 * nsselect.m (Fx_own_selection_internal)
13676 (Fx_disown_selection_internal, Fx_selection_exists_p)
13677 (Fx_selection_owner_p, Fx_get_selection_internal):
13678 Sync docs and argument specs with the xselect.c versions.
13680 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
13682 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
13684 2012-02-11 Eli Zaretskii <eliz@gnu.org>
13686 * w32select.c (Fx_selection_exists_p): Sync doc string and
13687 argument list with xselect.c. (Bug#10783)
13689 * w16select.c (Fx_selection_exists_p): Sync doc string and
13690 argument list with xselect.c. (Bug#10783)

13700 2012-02-07 Chong Yidong <cyd@gnu.org>
13702 * buffer.c (Fbuffer_local_variables)
13703 (buffer_lisp_local_variables): Handle unbound vars correctly;
13704 don't let Qunbound leak into Lisp.
13706 2012-02-07 Glenn Morris <rgm@gnu.org>
13708 * image.c (Fimagemagick_types): Doc fix.
13710 * image.c (imagemagick-render-type): Change it from a lisp object
13711 to an integer. Move the doc here from the lisp manual.
13712 Treat all values not equal to 0 the same.
13714 2012-02-06 Chong Yidong <cyd@gnu.org>
13716 * doc.c (store_function_docstring): Avoid applying docstring of
13717 alias to base function (Bug#2603).

13731 Include --enable-checking, if specified, in the return value.
13733 2012-02-04 Martin Rudalics <rudalics@gmx.at>
13735 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
13736 after rounding frame sizes. (Bug#9723)

14220 Use `Fword_search_regexp' instead of `wordify'. Doc fix.
14221 (syms_of_search): Define `Sword_search_regexp'. (Bug#10145)
14223 2011-12-01 Stefan Monnier <monnier@iro.umontreal.ca>
14225 * fileio.c (Finsert_file_contents): Move after-change-function call
14226 to before the "handled:" label, since all "goto handled" appear in
14227 cases where the *-change-functions have already been properly called
14230 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
14232 * keyboard.c (interrupt_signal): Don't call kill-emacs when
14233 waiting for input. (Bug#10169)
14235 2011-11-30 Eli Zaretskii <eliz@gnu.org>
14237 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
14238 verifies glyph row's hash code--we have just reallocated the
14239 glyphs, so their contents can be complete garbage. (Bug#10164)
14241 2011-11-30 Juanma Barranquero <lekktu@gmail.com>
14243 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Add missing check.

14247 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Ensure ROW's
14248 attributes are tested _before_ calling verify_row_hash, to protect
14249 against GCC re-ordering of the tests. (Bug#10164)
14251 2011-11-29 Jan Djärv <jan.h.d@swipnet.se>

14272 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
14273 of scroll runs so as to avoid assigning disabled bogus rows and
14274 unnecessary graphics copy operations.
14276 2011-11-27 Eli Zaretskii <eliz@gnu.org>
14278 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.

14281 (malloc, free, realloc, calloc): Redirect to e_* only when
14284 * lisp.h (GCTYPEBITS): Move before first use.
14285 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
14286 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
14287 this macro definition.
14289 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
14292 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>
14294 * gtkutil.c (xg_create_frame_widgets):

14305 Rename locals to avoid shadowing.
14306 * fileio.c (Finsert_file_contents):
14307 Rename inner 'gcpro1' to 'inner_gcpro1' to avoid shadowing.
14308 * process.c (wait_reading_process_output):
14309 Rename inner 'proc' to 'p' to avoid shadowing.
14310 Indent for consistency with usual Emacs style.
14312 2011-11-25 Eli Zaretskii <eliz@gnu.org>
14314 * xdisp.c (redisplay_window): If cursor row is not fully visible
14315 after recentering, and scroll-conservatively is set to a large
14316 number, scroll window by a few more lines to make the cursor fully
14317 visible and out of scroll-margin. (Bug#10105)
14318 (start_display): Don't move to the next line if the display should
14319 start at a newline that is part of a display vector or an overlay
14320 string. (Bug#10119)
14322 2011-11-24 Juri Linkov <juri@jurta.org>
14324 * image.c (imagemagick_load_image): Move `MagickSetResolution' down

14343 using it (Bug#5984).
14345 2011-11-22 Eli Zaretskii <eliz@gnu.org>
14347 * dispnew.c (adjust_glyph_matrix): Don't verify hash code of mode-
14348 and header-lines, as they don't have one computed for them.
14351 * .gdbinit (prow): Make displayed values more self-explaining.
14352 Add row's hash code.
14354 2011-11-21 Lars Magne Ingebrigtsen <larsi@gnus.org>

14397 2011-11-20 Paul Eggert <eggert@cs.ucla.edu>
14399 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
14400 Otherwise, valgrind does not work on some platforms.
14401 Problem reported by Andreas Schwab in
14402 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
14403 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14404 is set, removing the need for VIRT_ADDRESS_VARIES.
14405 (PURE_P): Use a more-efficient implementation that needs just one
14406 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14407 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14408 to 4 (xorl, subq, cmpq, setbe).
14409 * alloc.c (pure): Always extern now, since that's the
14410 VIRT_ADDR_VARIES behavior.
14411 (PURE_POINTER_P): Use a single comparison, not two, for
14412 consistency with the new puresize.h.
14413 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14414 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
14415 Remove VIRT_ADDR_VARIES no longer needed.
14417 2011-11-19 Eli Zaretskii <eliz@gnu.org>
14419 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
14420 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14421 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14422 behave as if the cursor position were at the window margin.
14424 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14425 and the cursor position is out of bounds, behave as if the cursor
14426 position were at the window margin. (Bug#10075)
14428 2011-11-18 Chong Yidong <cyd@gnu.org>
14430 * window.c (Fwindow_combination_limit): Make first argument
14431 non-optional, since it is meaningless for live windows like the

14441 (graft_intervals_into_buffer): Simplify.
14443 2011-11-18 Eli Zaretskii <eliz@gnu.org>
14445 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
14446 hash values of the two rows.
14447 (copy_row_except_pointers): Preserve the used[] arrays and the
14448 hash values of the two rows. (Bug#10035)
14449 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
14451 * xdisp.c (row_hash): New function, body extracted from
14452 compute_line_metrics.
14453 (compute_line_metrics): Call row_hash, instead of computing the
14456 * dispnew.c (verify_row_hash): Call row_hash for computing the
14457 hash code of a row, instead of duplicating code from xdisp.c.
14459 * dispextern.h (row_hash): Add prototype.
14461 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14463 * frame.c (delete_frame): Don't delete the terminal when the last
14464 X frame is closed if emacs is built with GTK toolkit.

14484 * window.h (window): Rename slot "nest" to "combination_limit".
14485 * window.c (Fwindow_nest): Rename to Fwindow_combination_limit.
14486 (Fset_window_nest): Rename to Fset_window_combination_limit.
14487 (Vwindow_nest): Rename to Vwindow_combination_limit.
14488 (recombine_windows, make_parent_window, make_window)
14489 (Fsplit_window_internal, saved_window)
14490 (Fset_window_configuration, save_window_save): Rename all
14491 occurrences of window_nest to window_combination_limit.
14493 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
14495 * image.c (imagemagick_load_image): Fix typo.
14497 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14499 * xdisp.c (display_line): Move the call to
14500 highlight_trailing_whitespace before the call to
14501 compute_line_metrics, since the latter needs to see the final
14502 faces of all the glyphs to compute ROW's hash value.
14503 Fixes assertion violations in row_equal_p. (Bug#10035)
14505 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14507 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
14508 just return (bug#10044).
14510 2011-11-12 Eli Zaretskii <eliz@gnu.org>
14512 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14513 with user-defined heap size. Bump the default size of the temacs
14514 heap to 27MB, to avoid memory warning when running temacs.
14515 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
14517 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14518 current_matrix and desired_matrix. (Bug#9990)
14519 (verify_row_hash) [XASSERTS]: New function.
14520 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
14521 that the hash value of glyph rows is correct.

14537 * nsfns.m (unwind_create_frame):
14538 * w32fns.c (unwind_create_frame): Use Fmemq to check if frame is in
14539 Vframe_list (Bug#9999).

14550 2011-11-11 Johan Bockgård <bojohan@gnu.org>
14552 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
14553 avoid a crash (bug#9496).
14555 2011-11-09 Chong Yidong <cyd@gnu.org>
14557 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

14564 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
14566 Avoid some portability problems by eschewing 'extern inline' functions.
14567 The trivial performance wins aren't worth the portability hassles; see
14568 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14570 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14571 (window_box_width, window_box_left, window_box_left_offset)
14572 (window_box_right, window_box_right_offset): Undo previous change,
14573 by removing the "extern"s.
14574 * intervals.c (adjust_intervals_for_insertion)
14575 (adjust_intervals_for_deletion): Undo previous change,
14576 making these static again.
14577 (offset_intervals, temp_set_point_both, temp_set_point)
14578 (copy_intervals_to_string): No longer inline.
14579 * xdisp.c (window_text_bottom_y, window_box_width)

14607 * window.c (Fwindow_nest, Fset_window_nest)
14608 (Fset_window_new_total, Fset_window_new_normal)
14609 (Fwindow_resize_apply): Don't use term subwindow in doc-strings.
14610 (delete_all_subwindows): Rename to delete_all_child_windows.
14611 (Fdelete_other_windows_internal, Fset_window_configuration):
14612 Call delete_all_child_windows instead of delete_all_subwindows.
14613 * frame.c (delete_frame): Call delete_all_child_windows instead
14614 of delete_all_subwindows.
14616 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
14618 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
14619 This is also needed for porting to any host where GC_MARK_STACK is
14620 not GC_MAKE_GCPROS_NOOPS.
14621 (which_symbols): Use it.
14623 2011-11-07 Kenichi Handa <handa@m17n.org>
14625 * coding.c (coding_set_destination): Check coding->src_pos only
14626 when coding->src_object is a buffer (bug#9910).

14632 process_coding to 0 (bug#9912).
14634 2011-11-06 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14636 * xmenu.c (cleanup_widget_value_tree): New function.
14637 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14638 calling free_menubar_widget_value_tree directly (Bug#9830).
14640 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
14642 Fix some portability problems with 'inline'.
14643 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14644 (window_box_width, window_box_left, window_box_left_offset)
14645 (window_box_right, window_box_right_offset): Declare extern.
14646 Otherwise, these inline functions do not conform to C99 and
14647 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14648 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14649 * intervals.c (adjust_intervals_for_insertion)
14650 (adjust_intervals_for_deletion): Now extern, because otherwise the
14651 extern inline functions 'offset_intervals' couldn't refer to it.
14652 (static_offset_intervals): Remove.
14653 (offset_intervals): Rewrite using the old contents of
14654 static_offset_intervals. The old version didn't conform to C99
14655 because an extern inline function contained a reference to an
14656 identifier with static linkage.
14658 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
14660 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

14678 (Fwindow_vscroll): Doc fix.
14679 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
14680 argument, since it makes no sense to pass a live window and for
14681 consistency with window-child.

14891 (w32font_open_internal, compute_metrics):
14892 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14893 instead of calling the "wide" APIs directly.
14895 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
14897 * w32.h (syms_of_w32font): Add prototype.

14939 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
14941 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
14943 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
14945 * keyboard.c (test_undefined): New function (bug#9751).
14946 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
14948 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
14950 * sysdep.c (init_sys_modes): Fix the check for the controlling
14951 terminal (Bug#6649).
14953 2011-10-20 Eli Zaretskii <eliz@gnu.org>
14955 * dispextern.h (struct bidi_it): New member next_en_type.
14957 * bidi.c (bidi_line_init): Initialize the next_en_type member.
14958 (bidi_resolve_explicit_1): When next_en_pos is valid for the
14959 current character, check also for next_en_type being WEAK_EN.
14960 (bidi_resolve_weak): Don't enter the expensive loop if the current
14961 position is before next_en_pos. Record the bidi type of the first
14962 non-ET, non-BN character we find, in addition to its position.
14963 (bidi_level_of_next_char): Invalidate next_en_type when
14964 next_en_pos is over-stepped.
14966 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14968 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14969 * editfns.c: Rewrite current-time-zone so that it invokes
14970 the equivalent of (format-time-string "%Z") to get the time zone name.
14971 This fixes a bug when the time zone name contains characters that
14972 need converting from the system time locale to Emacs internal format.
14973 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14974 that patch fixed format-time-string to do the conversion, but
14975 I forgot to fix current-time-zone.
14976 (format_time_string): New function, containing most of
14977 what Fformat_time_string used to contain.
14978 (Fformat_time_string): Rewrite in terms of format_time_string.
14979 This doesn't change this function's behavior.
14980 (current-time-zone): Rewrite to use format_time_string.
14981 This fixes the bug reported by Michael Schierl in
14982 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14983 Jason Rumney's 2007-06-07 change worked around this bug, but
14985 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14987 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14989 * xdisp.c (start_display): If the character at POS is displayed
14990 via a display vector, reset IT->current.dpvec_index to zero.
14991 (try_window_reusing_current_matrix): If a line ends in a display
14992 vector or the next line starts in a display vector, continue
14993 redrawing the window even though the character position of
14994 start_row was reached.
14997 2011-10-18 Chong Yidong <cyd@gnu.org>
14999 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15000 with nobreak-char-display too.
15002 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15004 Fix part 3 of bug#9771.
15005 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15006 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15007 non-neutral characters if the current character is a paragraph
15008 separator (a.k.a. Newline). This avoids running the same
15009 expensive loop twice, once when we consume the preceding newline
15010 and the other time when the line actually needs to be displayed.
15011 Avoid the loop when we see neutrals on the base embedding level
15012 following a character whose directionality is the same as the
15013 paragraph's. This avoids running the expensive loop when a line
15014 ends in a long sequence of neutrals, like control characters.
15015 Add assertion against STRONG_AL type. Slightly rearrange code
15016 that determines the type of a neutral given the first non-neutral
15018 (bidi_level_of_next_char): Set next_en_pos to zero when
15019 invalidating its info.
15021 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15023 * xdisp.c (push_display_prop): Determine whether to record string
15024 or buffer position by IT->string, not by IT->method. Allow
15025 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15026 (move_it_vertically_backward): Don't look for character position
15027 immediately after the newline when in a continuation line.
15030 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15032 * window.c (coordinates_in_window): Rewrite and delabelize
15033 vertical border check. (Bug#5357) (Bug#9618)
15035 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15037 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15038 errors in XSetWindowBorder (bug#9310).
15040 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15042 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15043 avoid crash when xmalloc overrun checking is enabled.
15045 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15047 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15048 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15049 cursor motion with <left> and <right> arrow keys.
15051 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15052 some callers set that themselves.
15054 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15056 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15057 display string and the previous row comes from the same string and
15058 is empty. (Bug#9739) (Bug#9738)
15060 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15062 * doc.c (get_doc_string): Encode file name (bug#9735).
15064 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15066 * bidi.c (bidi_level_of_next_char):
15067 * xdisp.c (get_visually_first_element): Remove old incorrect
15068 comments regarding the Unicode Line Separator character.
15070 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15072 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15074 * alloc.c (Fgc_status): Do not access beyond zombies array
15075 boundary if nzombies > MAX_ZOMBIES.
15076 * alloc.c (dump_zombies): Add missing format specifier.
15078 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15080 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15081 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15083 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15084 Some packages use them to denote characters with modifiers.
15086 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15088 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15089 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15090 matching a pp-number. Rename parameter var to var1.
15092 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15094 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15096 2011-10-08 Glenn Morris <rgm@gnu.org>
15098 * callint.c (Fcall_interactively): Give a more explicit error for the
15099 'c' case with a non-character input. (Bug#8479)
15101 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15103 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15105 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15106 lines that are hscrolled on the left.
15108 * dispnew.c (buffer_posn_from_coords): Account for a possible
15109 presence of header-line. (Bug#4426)
15111 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15113 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15114 Don't advertise functionality which we discourage or doesn't work.
15116 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15118 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15119 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15120 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15121 this makes Emacs dump core during garbage collection on rare
15122 occasions. sizeof is obviously inferior to offsetof here, so
15123 stick with offsetof.
15124 (GC_POINTER_ALIGNMENT): New macro.
15125 (mark_memory): Omit 3rd (offset) arg; caller changed.
15126 Don't assume EMACS_INT alignment is the same as pointer alignment.
15128 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15130 * keyboard.c (read_key_sequence_remapped): New var.
15131 (read_key_sequence): Compute remapping in the right buffer.
15132 (command_loop_1): Use read_key_sequence's remapping directly.
15134 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15136 * dired.c (file_name_completion): Don't expand file name.
15137 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15138 before checking file name handler.
15140 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15141 they've been requested explicitly (bug#9591).
15143 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15145 * keymap.c (Fsingle_key_description): Use make_specified_string
15146 instead of build_string to build string from push_key_description.
15149 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15151 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15152 This fixes a Y2038 bug on 64-bit hosts.
15153 * buffer.c (reset_buffer):
15154 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15155 (Fclear_buffer_auto_save_failure):
15156 Use 0, not -1, to represent an unset failure time, since time_t
15157 might not be signed.
15159 Remove dependency on glibc malloc internals.
15160 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15161 Move back here from lisp.h, but with their new implementations.
15162 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15163 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15164 * charset.c (charset_table_init): New static var.
15165 (syms_of_charset): Use it instead of xmalloc. This removes a
15166 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15167 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15168 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15169 Move back to alloc.c.
15170 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15171 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15173 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15175 * nsterm.m (windowDidResize): Call x_set_window_size only when
15176 ns_in_resize is true. Otherwise set pixelwidth/height and
15177 call change_frame_size (Bug#9628).
15179 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15181 Port --enable-checking=all to Fedora 14 x86-64.
15182 * charset.c (syms_of_charset): Also account for glibc malloc's
15183 internal overhead when calculating the initial malloc maximum.
15185 Port --enable-checking=all to Fedora 14 x86.
15186 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15188 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15189 (overrun_check_realloc, overrun_check_free):
15190 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15191 That way, xmalloc returns a properly-aligned pointer even if
15192 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15193 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15194 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15195 into account when calculating the initial malloc maximum.
15196 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15197 Move here from alloc.c, so that charset.c can use it too.
15198 Properly align; the old code wasn't right for common 32-bit hosts
15199 when configured with --enable-checking=all.
15200 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15201 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15203 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15205 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15208 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15210 * xdisp.c (compute_display_string_end): If there's no display
15211 string at CHARPOS, return -1.
15213 * bidi.c (bidi_fetch_char): When compute_display_string_end
15214 returns a negative value, treat the character as a normal
15215 character not covered by a display string. (Bug#9624)
15217 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15219 * lread.c (Fread_from_string): Fix typo in docstring.
15221 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15223 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15224 newline, reseat the iterator instead of bidi-iterating there one
15225 character at a time. (Bug#9610)
15226 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15227 TO_CHARPOS if the bidi iterator is at base embedding level.
15229 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15231 * lread.c (readevalloop): Use correct code for NBSP.
15232 (read1): Likewise. (Bug#9608)
15234 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15236 * dbusbind.c (Fdbus_register_signal): When service is not
15237 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15239 2011-09-25 Glenn Morris <rgm@gnu.org>
15241 * buffer.c (truncate-lines): Doc fix.
15243 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15245 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15246 (Fset_window_next_buffers): Doc fix.
15248 2011-09-24 Glenn Morris <rgm@gnu.org>
15250 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15252 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15254 Fix minor problems found by static checking.
15255 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15256 * indent.c (Fvertical_motion): Fix == vs = typo.
15258 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15260 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15261 Default value is now t. Doc fix.
15263 * indent.c (Fvertical_motion): Compute and apply the overshoot
15264 logic when moving up, not only when moving down. Fix the
15265 confusing name and values of the it_overshoot_expected variable;
15266 logic changes accordingly. (Bug#9254) (Bug#9549)
15268 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15269 CHARPOS is covered by a display string which includes newlines.
15270 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15271 is covered by a display string with embedded newlines.
15273 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15275 * dbusbind.c (Fdbus_register_signal): Add match rule to
15276 Vdbus_registered_objects_table. (Bug#9581)
15277 (Fdbus_register_method, Vdbus_registered_objects_table):
15280 2011-09-24 Jim Meyering <meyering@redhat.com>
15282 do not ignore write error for any output size
15283 The previous change was incomplete.
15284 While it makes emacs --batch detect the vast majority of stdout
15285 write failures, errors were still ignored whenever the output size is
15286 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15287 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15288 && echo FAIL: ignored write error
15289 FAIL: ignored write error
15290 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15291 && echo FAIL: ignored write error
15292 FAIL: ignored write error
15293 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15295 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15297 * emacs.c (Fkill_emacs): In noninteractive mode exit
15298 non-successfully if a write error occurred on stdout. (Bug#9574)
15300 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15302 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15305 * dispextern.h (struct it): Update the comment documenting what
15308 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15310 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15311 a display string, extend search for cursor position to end of row.
15312 (find_row_edges): If the row ends in a newline from a display
15313 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15314 Handle the case of a display string with multiple newlines.
15315 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15316 non-empty line. Fixes confusing cursor motion with arrow keys at
15317 the beginning of a line that starts with whitespace.
15319 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15321 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15324 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15326 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15327 boolean (Bug#9154).
15329 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15331 * xdisp.c (display_line): Record maximum and minimum buffer
15332 positions even if no glyphs were produced (e.g., by a zero-width
15333 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15334 buffer positions that will be removed from the glyph row because
15336 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15337 column is beyond frame width: don't subtract 1 "pixel" when
15338 computing width of the stretch.
15339 (reseat_at_next_visible_line_start): Undo the change made on
15340 2011-09-17 that saved paragraph information and restored it after
15341 the call to `reseat'. (Bug#9545)
15343 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15345 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15346 and turn window cursor on if cleared (Bug#9415).
15348 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15350 * search.c (boyer_moore): Take unibyte characters from pattern
15351 literally. (Bug#9458)
15353 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15355 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15357 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15359 Fix minor problem found by static checking.
15360 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15361 initialized, to pacify gcc -Wuninitialized.
15363 * fileio.c: Report proper errno when syscall falls.
15364 (Finsert_file_contents): Save and restore errno,
15365 so that report_file_error outputs the correct diagnostic.
15366 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15368 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15370 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15372 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15374 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15375 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15377 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15379 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15380 about the current paragraph and restore it after the call to reseat.
15382 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15383 (bidi_find_paragraph_start): Search back for paragraph beginning
15384 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15385 (bidi_move_to_visually_next): Only trigger paragraph-related
15386 computations when the last character is a newline or at EOB, not
15387 just any NEUTRAL_B. (Bug#9470)
15389 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15390 truncated lines if point is covered by a display string. (Bug#9524)
15392 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15394 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15395 (cons_to_x_long): New function.
15396 (lisp_data_to_selection_data): Use it. Correct the test for
15397 short-versus-long data; it was negated. Break out of vector
15398 loop, for efficiency, when a long datum is discovered.
15400 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15402 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15404 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15406 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15407 GCC PR/17406) by declaring this function with external scope.
15409 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15411 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15412 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15414 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15416 * editfns.c (Fformat): Correctly handle text properties on "%%".

15424 * xdisp.c (get_next_display_element)
15425 (fill_composite_glyph_string): Add comments about special meaning
15426 of TAB characters in a composition.
15428 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15430 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15431 This occurs when processing a multibyte format.
15432 Problem reported by Wolfgang Jenker.
15434 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15436 * xdisp.c (try_cursor_movement): Only check for exact match if
15437 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15439 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15441 Remove unused external symbols.
15442 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15443 * xdisp.c (calc_pixel_width_or_height): Now static.
15444 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15445 * indent.c (check_display_width):
15446 * w32term.c: Fix comment to match code.
15447 * xterm.c, xterm.h (x_catching_errors): Remove.
15449 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15451 * xselect.c: Use signed conversions more consistently (Bug#9498).
15452 (selection_data_to_lisp_data): Assume incoming selection data are
15453 signed integers, not unsigned. This is to be consistent with
15454 outgoing selection data, which was modified to use signed integers
15455 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15456 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15457 expects long, not unsigned long.
15459 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15461 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15462 computation of loop end. Reported by Johan Bockgård
15465 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15467 * frame.c (Fother_visible_frames_p): Function deleted.
15469 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15471 * indent.c (compute_motion): Process display vector front to back
15472 rather than the other way around. (Bug#2496)
15474 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15476 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15478 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15480 * minibuf.c (Fread_from_minibuffer): Doc fix.
15482 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15484 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15485 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15487 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15489 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15490 value for non-existent files.
15492 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15494 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15495 set its "size" to -1. This will set the modtime_size field of
15496 the corresponding buffer to -1, which is what
15497 verify-visited-file-modtime expects for files that do not exist.
15500 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15502 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15504 * lisp.h: ... from here. push_key_description is no longer
15505 defined in keyboard.c, so its declaration should not be in
15506 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15507 logically belongs with push_key_description.
15509 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15511 * buffer.h: Include <sys/types.h> instead of <time.h>.
15512 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15513 Problem reported by Herbert J. Skuhra.
15515 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15517 * xml.c (parse_region): Make the parsing work for
15518 non-comment-starting XML files again (bug#9144).
15520 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15522 * image.c (gif_load): Fix calculation of bottom and right corner.
15525 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15527 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15528 redisplay in small windows.
15530 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15532 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15534 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15536 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15537 Operate on live windows only.
15539 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15541 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15543 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15545 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15546 only under bidi iteration.
15548 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15550 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15552 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15554 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15555 Without this fix, the command to link temacs failed due to an
15556 undefined symbol __builtin_isnan. This is because
15557 /usr/include/iso/math_c99.h #defines isnan(x) to
15558 __builtin_isnan(x), but the bundled gcc, which identifies itself
15559 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15561 * floatfns.c (isnan): #undef, and then #define to a clone of
15563 (Fisnan): Always define, since it's always available now.
15564 (syms_of_floatfns): Always define isnan at the Lisp level.
15566 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15568 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15570 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15572 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15573 The previous code assumed that file offsets (off_t values) fit in
15574 EMACS_INT variables, which is not true on typical 32-bit hosts.
15575 The code messed up by falsely reporting buffer overflow in cases
15576 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15577 when "big" contains more than 2**29 bytes, even though this
15578 inserts just one byte and does not overflow the buffer.
15579 (Finsert_file_contents): Store file offsets as off_t
15580 values, not as EMACS_INT values. Check for overflow when
15581 converting between EMACS_INT and off_t. When checking for
15582 buffer overflow or for overlap, take the offsets into account.
15583 Don't use EMACS_INT for small values where int suffices.
15584 When checking for overlap, fix a typo: ZV was used where
15585 ZV_BYTE was intended.
15586 (Fwrite_region): Don't assume off_t fits into 'long'.
15587 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15589 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15591 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15593 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15595 sprintf-related integer and memory overflow issues (Bug#9412).
15597 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15598 (esprintf, exprintf, evxprintf): New functions.
15599 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15600 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15601 (modify_event_symbol): Do not assume that the length of
15602 name_alist_or_stem is safe to alloca and fits in int.
15603 (Fexecute_extended_command): Likewise for function name and binding.
15604 (Frecursion_depth): Wrap around reliably on integer overflow.
15605 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15606 since some callers pass EMACS_INT values.
15607 (Fsingle_key_description): Don't crash if symbol name contains more
15608 than MAX_ALLOCA bytes.
15609 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15610 (get_minibuffer): Arg is now EMACS_INT, not int.
15611 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15612 (esprintf, exprintf, evxprintf): New decls.
15613 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15615 * dbusbind.c (signature_cat): New function.
15616 (xd_signature, Fdbus_register_signal):
15617 Do not overrun buffer; instead, report string overflow.
15619 * dispnew.c (add_window_display_history): Don't overrun buffer.
15620 Truncate instead; this is OK since it's just a log.
15622 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15623 even if the time zone offset is outlandishly large.
15624 Don't mishandle offset == INT_MIN.
15626 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15627 when creating daemon; the previous buffer-overflow check was incorrect.
15629 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15630 which has the guts of the old verror function.
15632 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15633 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15635 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15636 (font_unparse_xlfd): Don't blindly alloca long strings.
15637 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15638 fits in int, when using sprintf. Use single snprintf to count
15639 length of string rather than counting it via multiple sprintfs;
15640 that's simpler and more reliable.
15641 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15642 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15643 sprintf, in case result does not fit in int.
15645 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15646 (fontset_from_font): Print it.
15648 * frame.c (tty_frame_count): Now printmax_t, not int.
15649 (make_terminal_frame, set_term_frame_name): Print it.
15650 (x_report_frame_params): In X, window IDs are unsigned long,
15651 not signed long, so print them as unsigned.
15652 (validate_x_resource_name): Check for implausibly long names,
15653 and don't assume name length fits in 'int'.
15654 (x_get_resource_string): Don't blindly alloca invocation name;
15655 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15658 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15659 (xg_check_special_colors, xg_set_geometry):
15660 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15662 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15663 Use esprintf, not sprintf, in case result does not fit in int.
15665 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15666 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15667 it as a large positive number.
15668 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15669 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15671 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15672 in case result does not fit in int.
15674 * print.c (float_to_string): Detect width overflow more reliably.
15675 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15676 buffer overrun. Don't assume list length fits in 'int'. Treat
15677 print length of 0 as 0, not as infinity; to be consistent with other
15678 uses of print length in this function. Don't overflow print length
15679 index. Don't assume hash table size fits in 'long', or that
15680 vectorlike size fits in 'unsigned long'.
15682 * process.c (make_process): Use printmax_t, not int, to format
15683 process-name gensyms.
15685 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15687 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15688 to avoid potential buffer overrun.
15690 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15691 if X resource line is longer than 512 bytes.
15693 * xfns.c (x_window): Make sprintf buffer a bit bigger
15694 to avoid potential buffer overrun.
15696 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15698 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15700 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15702 Integer overflow fixes for scrolling, etc.
15703 Without these, Emacs silently mishandles large integers sometimes.
15704 For example, "C-u 4294967297 M-x recenter" was treated as if
15705 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15707 * xdisp.c (try_window_id): Check Emacs fixnum range before
15708 converting to 'int'.
15710 * window.c (window_scroll_line_based, Frecenter):
15711 Check that an Emacs fixnum is in range before assigning it to 'int'.
15712 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15713 values converted from Emacs fixnums.
15714 (Frecenter): Don't wrap around a line count if it is out of 'int'
15715 range; instead, treat it as an extreme value.
15716 (Fset_window_configuration, compare_window_configurations):
15717 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15719 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15720 that can exceed INT_MAX. Check that EMACS_INT value is in range
15721 before assigning it to the (possibly-narrower) index.
15722 (match_limit): Don't assume that a fixnum can fit in 'int'.
15724 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15727 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15728 (Fvertical_motion): Don't wrap around LINES values that don't fit
15729 in 'int'. Instead, treat them as extreme values. This is good
15730 enough for windows, which can't have more than INT_MAX lines anyway.
15732 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15734 * Require libxml/parser.h to avoid compilation warning.
15736 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15738 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15739 since this reportedly can destroy thread storage.
15741 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15743 * syntax.c (find_defun_start): Update all cache variables if
15744 exiting early (Bug#9401).
15746 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15748 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15750 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15751 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15752 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15754 * term.c (tty_append_glyph): New function.
15755 (produce_stretch_glyph): Static function and its prototype deleted.
15757 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15760 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15762 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15763 when checking :margin (Bug#9390).
15764 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15765 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15766 so that the name doesn't mislead. All uses changed.
15768 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15770 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15773 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15775 * xdisp.c (move_it_to): Don't bail out early when reaching
15776 position beyond to_charpos, if we are scanning backwards.
15777 (move_it_vertically_backward): When DY == 0, make sure we get to
15778 the first character in the line after the newline.
15780 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15782 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15783 (ccl_driver): Do not generate an out-of-range pointer.
15784 (Fccl_execute_on_string): Remove unnecessary check for
15785 integer overflow, noted by Stefan Monnier in
15786 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15787 Remove a FIXME that didn't need fixing.
15788 Simplify the newly-introduced buffer reallocation code.
15790 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15792 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15794 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15796 Integer and memory overflow issues (Bug#9196).
15798 * doc.c (get_doc_string): Rework so that
15799 get_doc_string_buffer_size is the actual buffer size, rather than
15800 being 1 less than the actual buffer size; this makes xpalloc more
15803 * image.c (x_allocate_bitmap_record, cache_image):
15804 * xselect.c (Fx_register_dnd_atom):
15805 Simplify previous changes by using xpalloc.
15807 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15808 since either will do and ptrdiff_t is convenient with xpalloc.
15810 * charset.c (charset_table_size)
15811 (struct charset_sort_data.priority): Now ptrdiff_t.
15812 (charset_compare): Don't overflow if priorities differ greatly.
15813 (Fsort_charsets): Don't assume list length fits in int.
15814 Check for size-calculation overflow when allocating sort data.
15815 (syms_of_charset): Allocate an initial charset table that is
15816 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15818 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15820 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15821 The actual value is always <= INT_MAX, and leaving it unsigned made
15822 overflow checking harder.
15824 * dispextern.h (struct glyph_matrix.rows_allocated)
15825 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15826 with xpalloc. The values are still always <= INT_MAX.
15828 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15830 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15831 (SAFE_NALLOCA): New macro.
15833 * region-cache.c (struct boundary.pos, find_cache_boundary)
15834 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15835 (set_cache_region, invalidate_region_cache)
15836 (revalidate_region_cache, know_region_cache, region_cache_forward)
15837 (region_cache_backward, pp_cache):
15838 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15839 so that ptrdiff_t * can be passed to xpalloc.
15840 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15841 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15842 (pp_cache): Don't assume cache_len fits in int.
15843 * region-cache.h: Adjust extern decls to match.
15845 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15846 EMACS_INT, since either will do, for xpalloc.
15848 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15849 (xnmalloc, xnrealloc, xpalloc): New functions.
15851 * bidi.c (bidi_shelve_header_size): New constant.
15852 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15853 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15855 * bidi.c (bidi_cache_shrink):
15856 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15858 Don't update size of array until after memory allocation succeeds,
15859 because xmalloc/xrealloc may not return.
15860 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15861 now that we have proper integer overflow checking.
15862 (record_overlay_string, overlay_strings): Catch overflows when
15863 calculating size of overlay_str_buf.
15865 * callproc.c (Fcall_process): Check for size overflow when
15866 calculating size of args2.
15867 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15868 Normally we prefer signed values, but sticking with ptrdiff_t would
15869 require adding more-complicated checks.
15871 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15872 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15873 Redo buffer-overflow calculations to avoid integer overflow.
15874 Add a FIXME comment where memory seems to be over-allocated.
15876 * character.c (Fstring): Check for size-calculation overflow.
15878 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15879 unnecessary integer overflow. Check for size overflow.
15880 (encode_coding_object): Don't update size until xmalloc succeeds.
15882 * composite.c (get_composition_id): Check for overflow in glyph
15883 length calculations.
15885 Integer and memory overflow fixes for display code.
15886 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15887 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15888 (scrolling_window): Check for overflow in size calculations.
15889 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15890 Don't assume glyph table len fits in int.

15892 (row_table_size): Now ptrdiff_t, not int.
15893 (scrolling_window): Avoid overflow in size calculations.
15894 Don't update size until allocation succeeds.
15895 * fns.c (concat): Check for overflow in size calculations.
15896 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15897 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15898 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15900 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15901 (get_doc_string): Check for size calculation overflow.
15902 Don't update size until allocation succeeds.
15903 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15904 EMACS_INT, where ptrdiff_t will do.
15905 (Fsubstitute_command_keys): Check for string overflow.
15907 * editfns.c (set_time_zone_rule): Don't assume environment length
15909 (message_length): Now ptrdiff_t, not int.
15910 (Fmessage_box): Don't update size until allocation succeeds.
15911 Don't assume message length fits in int.
15912 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15914 * emacs.c (main): Do not reallocate argv, since there is a null at
15915 the end that can be overwritten, and this way there's no need to
15916 worry about size-calculation overflow.
15917 (sort_args): Check for size-calculation overflow.
15919 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15921 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15923 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15924 (x_set_scroll_bar_width, x_figure_window_size):
15925 Check for integer overflow.
15926 (x_set_alpha): Do not assume XINT fits in int.
15928 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15929 This is for the members text_lines, text_cols, total_lines, total_cols,
15930 where the system imposes an 'int' limit.
15932 * fringe.c (Fdefine_fringe_bitmap):
15933 Don't update size until alloc works.
15935 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15936 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15938 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15939 Check for size-calculation overflow.
15940 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15941 do, as we prefer signed integers.
15942 (id_to_widget.max_size, id_to_widget.used)
15943 (xg_store_widget_in_map, xg_remove_widget_from_map)
15944 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
15945 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
15946 Use and return ptrdiff_t, not int.
15947 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
15948 * gtkutil.h: Change prototypes to match the above.
15950 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
15951 are duplicate now that they've been promoted to lisp.h.
15952 (x_allocate_bitmap_record, x_alloc_image_color)
15953 (make_image_cache, cache_image, xpm_load):
15954 Don't update size until alloc is done.
15955 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
15957 Check for size calculation overflow.
15958 (ct_colors_allocated_max): New constant.

15964 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
15965 Use ptrdiff_t, not int, to count maps.
15966 (read_char_minibuf_menu_prompt): Check for overflow in size
15967 calculations. Don't update size until allocation succeeds.
15968 Redo calculations to avoid overflow.
15969 * keyboard.h: Change prototypes to match the above.
15971 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
15973 (current_minor_maps): Check for size calculation overflow.
15974 * keymap.h: Change prototypes to match the above.
15976 * lread.c (read1, init_obarray): Don't update size until alloc done.
15978 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

15997 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15998 for command line length. Do not attempt to address one before the
15999 beginning of an array, as that's not portable.
16001 * term.c (max_frame_lines): Remove; unused.
16002 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
16004 (encode_terminal_code, calculate_costs): Check for size
16005 calculation overflow.
16006 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph

16023 Use ptrdiff_t, not int, for sizes.
16024 (store_mode_line_noprop_char): Don't update size until alloc done.

16027 Use ptrdiff_t, not int, for sizes.
16028 (Finternal_make_lisp_face, cache_face):
16029 Check for size calculation overflow.
16030 (cache_face): Treat size calculation overflows as if they were
16031 memory exhaustion (the usual treatment), rather than aborting.
16033 * xfns.c (x_encode_text, x_set_name_internal)
16034 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16035 sizes, since they can exceed INT_MAX in size. Check for size
16036 calculation overflow.
16038 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16039 (xg_select): Check for size calculation overflow.
16040 Don't update size until alloc done.
16042 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16043 as sprintf is limited to int lengths.
16045 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16046 (X_LONG_MIN): New macros.
16047 Use them to make the following changes clearer.
16048 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16049 This change doesn't affect the value now, but it may help remind
16050 future maintainers not to raise the value too much later.
16051 (SELECTION_QUANTUM): Remove, replacing with ...
16052 (selection_quantum): ... new function, which avoids overflow.
16054 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16055 assumption that selection length fits in 'int'.
16056 (x_reply_selection_request, x_handle_selection_request)
16057 (x_get_window_property, receive_incremental_selection)
16058 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
16059 (lisp_data_to_selection_data, clean_local_selection_data):
16060 Use ptrdiff_t, not int, to record length of selection.
16061 (x_reply_selection_request, x_get_window_property)
16062 (receive_incremental_selection, x_property_data_to_lisp):
16063 Redo calculations to avoid overflow.
16064 (x_reply_selection_request): When sending hint, ceiling it at
16065 X_LONG_MAX rather than relying on wraparound overflow to send
16067 (x_get_window_property, receive_incremental_selection)
16068 (lisp_data_to_selection_data, x_property_data_to_lisp):
16069 Check for size-calculation overflow.
16070 (x_get_window_property, receive_incremental_selection)

16072 Don't store size until memory allocation succeeds.
16073 (x_get_window_property): Plug memory leak on memory exhaustion.
16074 Don't double-block input; malloc is safe here. Don't assume 2**34
16075 - 4 fits in unsigned long. Add an xassert to check
16076 XGetWindowProperty overflow. Be more careful about overflow
16077 calculations, and distinguish size from memory overflow better.
16078 (receive_incremental_selection): When tracing, don't assume
16079 unsigned int is less than INT_MAX.
16080 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16081 harmful) conversions of unsigned short to int.
16082 (lisp_data_to_selection_data): Don't assume that integers
16083 in the range -65535 through -1 fit in an X unsigned short.
16084 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16085 result parameters unless successful. Rely on cons_to_unsigned
16086 to report problems with elements; the old code wasn't right anyway.
16087 (x_check_property_data): Check for int overflow; we cannot use
16088 a wider type due to X limits.
16089 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
16091 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
16093 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
16094 (x_term_init): Check for size calculation overflow.
16095 (x_color_cells): Don't store size until memory allocation succeeds.
16096 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
16097 Don't assume alloca size is less than MAX_ALLOCA.
16098 (x_term_init): Don't assume length fits in int (sprintf is limited
16101 Use ptrdiff_t for composition IDs.

16120 * image.c (xpm_get_color_table_h):
16121 * lisp.h (hash_lookup, hash_put):
16122 * minibuf.c (Ftest_completion):
16123 Use ptrdiff_t for hash table indexes, not int (which is too
16124 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16125 32-bit --with-wide-int hosts).
16127 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16128 Add a FIXME comment about memory leaks.
16129 (syms_of_charset): Don't assume xmalloc returns.

16133 * character.h (CHAR_WIDTH):
16134 * indent.c (MULTIBYTE_BYTES_WIDTH):
16135 Use sanitize_char_width to avoid undefined and/or bad behavior
16136 with outlandish widths.
16137 * character.h (sanitize_tab_width): Rename from sanitize_width,
16138 now that we have two such functions. All uses changed.
16139 (sanitize_char_width): New inline function.
16141 Don't assume that tab-width fits in int.
16142 * character.h (sanitize_width): New inline function.
16143 (SANE_TAB_WIDTH): New macro.
16144 (ASCII_CHAR_WIDTH): Use it.

16149 * fileio.c: Integer overflow issues with file modes.
16150 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
16152 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
16153 Remove unreachable code.
16154 (read_hex, load_charset_map_from_file): Check for integer overflow.
16156 * xterm.c: Don't go over XClientMessageEvent limit.
16157 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16158 (x_send_scroll_bar_event): Likewise. Check that the size does not
16159 exceed limits imposed by XClientMessageEvent, as well as the usual
16160 ptrdiff_t and size_t limits.
16162 * keyboard.c: Overflow, signedness and related fixes.
16163 (make_lispy_movement): Use same integer type in forward decl
16164 that is used in the definition.
16165 (read_key_sequence, keyremap_step):
16166 Change bufsize argument back to int, undoing my 2011-03-30 change.
16167 We prefer signed types, and int is wide enough here.
16168 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16169 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16170 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16171 length, not size_t. Use ptrdiff_t for index, not int.
16172 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16173 possibility of integer overflow.
16175 Overflow, signedness and related fixes for images.
16177 * dispextern.h (struct it.stack[0].u.image.image_id)
16178 (struct_it.image_id, struct image.id, struct image_cache.size)

16185 * xdisp.c (calc_pixel_width_or_height):
16186 * xfns.c (image_cache_refcount):
16187 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

16194 when the callers expect that.
16195 (image_ascent): Redo ascent calculation to avoid int overflow.
16196 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
16197 (lookup_image): Remove unnecessary tests.
16198 (xbm_image_p): Locals are now of int, not EMACS_INT,
16199 since parse_image_check makes sure they fit into int.
16200 (png_load, gif_load, svg_load_image):
16201 Prefer int to unsigned where either will do.
16202 (tiff_handler): New function, combining the cores of the
16203 old tiff_error_handler and tiff_warning_handler.
16204 This function is rewritten to use vsnprintf and thereby avoid
16205 stack buffer overflows. It uses only the features of vsnprintf
16206 that are common to both POSIX and native Microsoft.
16207 (tiff_error_handler, tiff_warning_handler): Use it.
16208 (tiff_load, gif_load, imagemagick_load_image):
16209 Don't assume :index value fits in 'int'.
16210 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16211 (imagemagick_load_image): Check that crop parameters fit into
16212 the integer types that MagickCropImage accepts. Don't assume
16213 Vimagemagick_render_type has a nonnegative value. Don't assume
16214 size_t fits in 'long'.
16215 (gs_load): Use printmax_t to print the widest integers possible.
16216 Check for integer overflow when computing image height and width.
16218 2011-08-26 Eli Zaretskii <eliz@gnu.org>
16220 * xdisp.c (redisplay_window): Don't force window start if point
16221 will be invisible in the resulting window. (Bug#9324)

16225 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
16226 the display spec is of the form `(space ...)'.
16227 (handle_display_spec): Return the value returned by
16228 handle_single_display_spec, not just 1 or zero.
16229 (handle_single_display_spec): If the display spec is of the form
16230 `(space ...)', and specifies display in the text area, return 2
16232 (try_cursor_movement): Check for the need to scroll more
16233 accurately, and prefer exact match for point under bidi.
16234 Don't advance `row' beyond the last row of the window.
16236 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16237 into disp_prop; all users changed.
16239 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
16240 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
16241 for the text covered by the display property.

16251 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16252 buffers, return left-to-right.
16253 (set_cursor_from_row): Consider candidate row a win if its glyph
16254 represents a newline and point is on that newline. Fixes cursor
16255 positioning on the newline at EOL of R2L text within L2R
16256 paragraph, and vice versa.
16257 (try_cursor_movement): Check continued rows, in addition to
16258 continuation rows. Fixes unwarranted scroll when point enters a
16259 continued line of R2L text within an L2R paragraph, or vice versa.
16260 (cursor_row_p): Consider the case of point being equal to
16261 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16262 from the end of a short line to the beginning of a continued line
16263 of R2L text within L2R paragraph.
16264 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
16265 composed characters.
16267 * bidi.c (bidi_check_type): Use xassert.

16280 2011-08-22 Kenichi Handa <handa@m17n.org>
16282 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
16283 extra slot even if the purpose is char-code-property-table.
16285 2011-08-23 Eli Zaretskii <eliz@gnu.org>
16287 * xdisp.c (redisplay_window): When computing centering_position,
16288 account for the height of the header line. (Bug#8874)
16290 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16291 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16292 candidate is selected by the mouse, and that candidate has a
16293 composed character under the mouse.
16295 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16296 coordinates reported by pos-visible-in-window-p for a composed
16297 character in column zero.
16299 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
16301 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
16303 2011-08-22 Eli Zaretskii <eliz@gnu.org>
16305 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16306 consider it a hit if to_charpos is anywhere in the range of the
16307 composed buffer positions.
16309 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16311 * image.c (gif_load): Don't assume that each subimage has the same
16312 dimensions as the base image. Handle disposal method that is
16313 "undefined" by the gif spec (Bug#9335).
16315 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16317 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16322 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16323 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16324 from an Org mode buffer to a Speedbar frame.
16326 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16327 a composition, take its buffer position from IT->cmp_it.charpos.
16328 Fixes cursor positioning at the beginning of a line that begins
16329 with a composed character.
16331 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16333 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16334 character bidirectional type, use STRONG_L instead. Fixes crashes
16335 in a buffer produced by `describe-categories'.
16337 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16338 members before the level stack, so they would be saved and
16339 restored when copying iterator state. Fixes incorrect reordering
16340 around TABs covered by display properties.
16342 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16344 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16368 Fix memory allocation problems in Cygwin build (Bug#9273).
16370 * unexcw.c ( __malloc_initialized): Declare external variable.
16371 (fixup_executable): Force the dumped emacs to reinitialize malloc.
16373 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
16375 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

16414 * xdisp.c (move_it_in_display_line_to): Don't invoke
16415 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16416 ppos_it. Fixes vertical cursor motion when line beginning is
16417 covered by an image. (Bug#9296)
16419 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16421 * nsterm.h (ns_run_ascript): Declare.

16425 (ns_run_ascript): New function.
16426 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16427 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16428 the event loop. Get status from as_status (Bug#7276).
16430 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16431 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16432 the event loop (Bug#7276).
16434 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16436 * gnutls.c (QCgnutls_bootprop_priority)

16457 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16458 (Fnetwork_interface_list): Allocate in increments of bytes instead
16459 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16460 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16462 (struct ifflag_def): notrailers is smart on OSX.
16463 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16464 Get hardware address with getifaddrs if available.
16466 2011-08-12 Eli Zaretskii <eliz@gnu.org>

16469 IT->position is set to within IT->object's boundaries. Break from
16470 the loop as soon as EOB is reached; avoids infloops in redisplay
16471 when IT->position is set up wrongly due to some bug.
16472 Set IT->current to match the bidi iterator unconditionally.
16473 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16474 entry. Force push_it to save on the stack the current
16475 buffer/string position, to be restored by pop_it. Fix flags in
16476 the iterator structure wrt the object coming from a display
16477 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16478 properties. (Bug#9284)
16480 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16482 * fontset.c (fontset_get_font_group): Add proper type checks.
16485 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16487 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
16488 and LC_VERSION_MIN_MACOSX.
16489 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16490 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16492 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16494 * xdisp.c (forward_to_next_line_start): Allow to use the
16495 no-display-properties-and-no-overlays under bidi display.
16496 Set disp_pos in the bidi iterator to avoid searches for display
16497 properties and overlays.
16499 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16501 * editfns.c (Fset_time_zone_rule): Document relationship with the
16504 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16505 the font entity extracted from the cache (Bug#8109).
16507 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16509 * composite.c (autocmp_chars): Don't reset point. That is done by
16510 restore_point_unwind (Bug#5984).
16512 2011-08-07 Juri Linkov <juri@jurta.org>
16514 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16515 to show the arg `TIME' instead of `TIMEVAL'.
16517 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16519 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16520 display property strides EOL and includes a newline, as in
16521 longlines-mode. (Bug#9254)
16522 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16523 word-wrap under bidirectional display. (Bug#9224)
16525 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16526 is non-zero, even if the data buffer is NULL. Fixes a crash in
16527 vertical-motion with longlines-mode. (Bug#9254)
16529 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16531 * bidi.c <bidi_cache_total_alloc>: Now static.
16532 (bidi_initialize): Initialize bidi_cache_total_alloc.
16534 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16537 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16538 amount allocated this far in `bidi_cache_total_alloc'.
16539 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16540 non-zero, only free the data buffer without restoring the cache
16541 contents. All callers changed.
16543 * dispextern.h (bidi_unshelve_cache): Update prototype.
16545 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16546 (move_it_in_display_line, move_it_to)
16547 (move_it_vertically_backward, move_it_by_lines): Replace the call
16548 to xfree to an equivalent call to bidi_unshelve_cache.
16549 (move_it_in_display_line_to): Fix logic of returning
16550 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16552 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16554 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16555 came from a string character with a `cursor' property. (Bug#9229)
16557 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16559 * Makefile.in (LIB_PTHREAD): New variable.
16560 (LIBES): Add LIB_PTHREAD (Bug#9216).
16562 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16563 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16565 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16567 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16569 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16571 * xterm.c (x_find_topmost_parent): New function.
16572 (x_set_frame_alpha): Find topmost parent window with
16573 x_find_topmost_parent and set the property there also (bug#9181).
16574 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16576 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16578 * callproc.c (Fcall_process): Avoid vfork clobbering
16579 the local vars buffer, coding_systems, current_dir.
16581 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16583 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16585 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16587 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16588 so that it is not optimized away.
16590 * xdisp.c (compute_display_string_pos): Remove unused local.
16592 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16594 Fix slow cursor motion and scrolling in large buffers with
16595 selective display, like Org Mode buffers. (Bug#9218)
16597 * dispextern.h (struct bidi_it): New member disp_prop_p.
16599 * xdisp.c: Remove one-slot cache of display string positions.
16600 (compute_display_string_pos): Accept an additional argument
16601 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16602 for a display string or property. If found, set DISP_PROP_P
16605 * bidi.c (bidi_fetch_char): Accept an additional argument
16606 DISP_PROP_P, and pass it to compute_display_string_pos.
16607 Only handle text covered by a display string if DISP_PROP_P is returned
16608 non-zero. All callers of bidi_fetch_char changed.
16610 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16612 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16614 2010-12-03 Don March <don@ohspite.net>
16616 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16617 last character M-[char] is translated to ESC [char] (bug#7541).
16619 2011-08-02 Kenichi Handa <handa@m17n.org>
16621 * lisp.h (uniprop_table): Extern it.
16623 * chartab.c (uniprop_table): Make it non-static.
16625 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16627 * xdisp.c (forward_to_next_line_start): Accept additional argument
16628 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16630 (reseat_at_next_visible_line_start): Use the bidi iterator state
16631 returned by forward_to_next_line_start to restore the state of
16632 it->bidi_it after backing up to previous newline. (Bug#9212)
16634 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16636 * regex.c (re_comp): Protoize.
16637 (re_exec): Fix return type.
16638 (regexec): Fix type of `ret'. (Bug#9203)
16640 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16642 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16643 This is needed if max-image-size is a floating-point number.
16645 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16647 * print.c (print_object): Print empty symbol as ##.
16649 * lread.c (read1): Read ## as empty symbol.
16651 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16653 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16654 setting frame foreground color (Bug#9175).
16655 (x_set_background_color): Likewise.
16657 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16658 contents (Bug#9176).
16659 (EmacsTooltip -init): Remove bezels and add shadows to
16662 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16663 or scroll bar (Bug#8470).
16665 * nsfont.m (nsfont_open): Remove assignment to voffset and
16666 unnecessary vars hshink, expand, hd, full_height, min_height.
16667 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16669 * nsterm.h (nsfont_info): Remove voffset field.
16671 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16673 Implement strike-through and overline on NextStep (Bug#8863).
16675 * nsfont.m (nsfont_open): Use underline position provided by font,
16676 instead of hard-coded value of 2.
16677 (nsfont_draw): Call ns_draw_text_decoration instead.
16679 * nsterm.h: Add declaration for ns_draw_text_decoration.
16681 * nsterm.m (ns_draw_text_decoration): New function for drawing
16682 underline, overline, and strike-through.
16683 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16684 ns_draw_text_decoration. Change treatment of cursor drawing to
16685 accommodate underlining, etc.
16687 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16689 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16692 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16694 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16695 Without this fix, if a signal arrives just after memory fills up,
16696 'malloc' might be invoked reentrantly.
16698 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16699 In other words, assume that every image size is allowed, on non-X
16700 hosts. This assumption is probably wrong, but it lets Emacs compile.
16702 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16704 * regex.c (re_iswctype): Convert return values to boolean.
16706 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16708 * xdisp.c (compute_display_string_pos): Don't use cached display
16709 string position if the buffer had its restriction changed.
16712 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16714 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16716 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16718 Integer signedness and overflow and related fixes. (Bug#9079)
16720 * bidi.c: Integer size and overflow fixes.
16721 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16722 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16723 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16724 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16725 (bidi_find_other_level_edge):
16726 Use ptrdiff_t instead of EMACS_INT where either will do.
16727 This works better on 32-bit hosts configured --with-wide-int.
16728 (bidi_cache_ensure_space): Check for size-calculation overflow.
16729 Use % rather than repeated addition, for better worst-case speed.
16730 Don't set bidi_cache_size until after xrealloc returns, because it
16732 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16733 (bidi_cache_ensure_space): Also check that the bidi cache size
16734 does not exceed that of the largest Lisp string or buffer. See Eli
16735 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16737 * alloc.c (__malloc_size_t): Remove.
16738 All uses replaced by size_t. See Andreas Schwab's note
16739 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16741 * image.c: Improve checking for integer overflow.
16742 (check_image_size): Assume that f is nonnull, since
16743 it is always nonnull in practice. This is one less thing to
16744 worry about when checking for integer overflow later.
16745 (x_check_image_size): New function, which checks for integer
16746 overflow issues inside X.
16747 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16748 This removes the need for a memory_full check.
16749 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16750 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16751 (xbm_read_bitmap_data): Change locals back to 'int', since
16752 their values must fit in 'int'.
16753 (xpm_load_image, png_load, tiff_load):
16754 Invoke x_create_x_image_and_pixmap earlier,
16755 to avoid much needless work if the image is too large.
16756 (tiff_load): Treat overly large images as if
16757 x_create_x_image_and_pixmap failed, not as malloc failures.
16758 (gs_load): Use x_check_image_size.
16760 * gtkutil.c: Omit integer casts.
16761 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16762 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16764 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16766 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16767 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16768 would wrongly return t on a 64-bit host.
16770 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16771 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16772 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16773 and therefore cause GCC to emit a bogus diagnostic in some cases.
16775 * image.c: Integer signedness and overflow and related fixes.
16776 This is not an exhaustive set of fixes, but it's time to
16777 record what I've got.
16778 (lookup_pixel_color, check_image_size): Remove redundant decls.
16779 (check_image_size): Don't assume that arbitrary EMACS_INT values
16780 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16781 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16782 (tiff_load, imagemagick_load_image):
16783 Check for overflow in size calculations.
16784 (x_create_x_image_and_pixmap): Remove unnecessary test for
16785 xmalloc returning NULL; that can't happen.
16786 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16787 (xpm_color_bucket): Use better integer hashing function.
16788 (xpm_cache_color): Don't possibly over-allocate memory.
16789 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16790 (gif_memory_source):
16791 Use ptrdiff_t, not int or size_t, to record sizes.
16792 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16793 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16794 either works, as we prefer signed integers.
16795 (tiff_read_from_memory, tiff_write_from_memory):
16796 Return tsize_t, not size_t, since that's what the TIFF API wants.
16797 (tiff_read_from_memory): Don't fail simply because the read would
16798 go past EOF; instead, return a short read.
16799 (tiff_load): Omit no-longer-needed casts.
16800 (Fimagemagick_types): Don't assume size fits into 'int'.
16802 Improve hashing quality when configured --with-wide-int.
16803 * fns.c (hash_string): New function, taken from sxhash_string.
16804 Do not discard information about ASCII character case; this
16805 discarding is no longer needed.
16806 (sxhash-string): Use it. Change sig to match it. Caller changed.
16807 * lisp.h: Declare it.
16808 * lread.c (hash_string): Remove, since we now use fns.c's version.
16809 The fns.c version returns a wider integer if --with-wide-int is
16810 specified, so this should help the quality of the hashing a bit.
16812 * emacs.c: Integer overflow minor fix.
16813 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16814 Define only if GNU_LINUX.
16815 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16817 * dispnew.c: Integer signedness and overflow fixes.
16818 Remove unnecessary forward decls, that were a maintenance hassle.
16819 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16821 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16822 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16823 (prepare_desired_row, line_draw_cost):
16824 Use int, not unsigned, where either works.
16825 (save_current_matrix, restore_current_matrix):
16826 Use ptrdiff_t, not size_t, where either works.
16827 (init_display): Check for overflow more accurately, and without
16828 relying on undefined behavior.
16830 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16831 Remove, replacing with the new symbols in lisp.h. All uses changed.
16832 * fileio.c (make_temp_name):
16833 * filelock.c (lock_file_1, lock_file):
16834 * xdisp.c (message_dolog):
16835 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16836 Use pMd etc. instead.
16837 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16838 replacing the pWIDE etc. symbols removed from editfns.c.
16840 * keyboard.h (num_input_events): Now uintmax_t.
16841 This is (very slightly) less likely to mess up due to wraparound.
16844 * buffer.c: Integer signedness fixes.
16845 (alloc_buffer_text, enlarge_buffer_text):
16846 Use ptrdiff_t rather than size_t when either will do, as we prefer
16849 * alloc.c: Integer signedness and overflow fixes.
16850 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16851 (__malloc_size_t): Default to size_t, not to int.
16852 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16853 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16854 Prefer ptrdiff_t to size_t when either would do, as we prefer
16856 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16857 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16858 Now const. Initialize with values that are in range even if char
16860 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16861 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16862 These functions do the right thing with sizes > 2**32.
16863 (check_depth): Now ptrdiff_t, not int.
16864 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16865 Adjust to new way of storing sizes. Check for size overflow bugs
16867 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16868 slightly wrong anyway, as it missed one instance of
16869 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16870 (refill_memory_reserve): Omit needless cast to size_t.
16871 (mark_object_loop_halt): Mark as externally visible.
16873 * xselect.c: Integer signedness and overflow fixes.
16874 (Fx_register_dnd_atom, x_handle_dnd_message):
16875 Use ptrdiff_t, not size_t, since we prefer signed.
16876 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16877 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16878 x_dnd_atoms_size and x_dnd_atoms_length.
16880 * doprnt.c: Prefer signed to unsigned when either works.
16882 * doprnt.c (doprnt):
16884 * xdisp.c (vmessage):
16885 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16886 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16887 prefer signed arithmetic to avoid comparison confusion.
16888 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16889 but is a bit tricky.
16891 Assume freestanding C89 headers, string.h, stdlib.h.
16892 * data.c, doprnt.c, floatfns.c, print.c:
16893 Include float.h unconditionally.
16894 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16895 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16896 * regex.c: Likewise for stddef.h, string.h.
16897 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16898 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16899 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16900 (STDC_HEADERS): Remove obsolete defines.
16901 * sysdep.c: Include limits.h unconditionally.
16903 Assume support for memcmp, memcpy, memmove, memset.
16904 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16905 * regex.c (memcmp, memcpy):
16906 Remove; we assume C89 now.
16908 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16909 (__malloc_safe_bcopy): Remove; no longer needed.
16911 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16912 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16913 well either way, and we prefer signed to unsigned.
16915 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16917 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16918 closes the connection while we're reading (bug#9182).
16920 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16922 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16923 are specified (Bug#9168).
16925 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16927 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16928 Found by GCC static checking and --with-wide-int on a 32-bit host.
16930 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16932 * xdisp.c (compute_display_string_pos): Fix logic of caching
16933 previous display string position. Initialize cached_prev_pos to
16934 -1. Fixes slow-down at the beginning of a buffer.
16936 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16938 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16939 for attrs[LFACE_FONTSET_INDEX].
16941 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16943 * xml.c (parse_region): Remove unused local
16944 that was recently introduced.
16946 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16948 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16949 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16951 * xdisp.c (move_it_in_display_line_to): Record the best matching
16952 position for TO_CHARPOS while scanning the line, and restore it on
16953 exit if none of the characters scanned was an exact match.
16954 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16955 when exact match is impossible due to invisible text, and the
16956 lines are truncated.
16958 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16960 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16963 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16965 Fix a significant slow-down of cursor motion with C-n, C-p,
16966 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16967 auto-repeat under bidi redisplay in fontified buffers.
16968 * xdisp.c (compute_stop_pos_backwards): New function.
16969 (next_element_from_buffer): Call compute_stop_pos_backwards to
16970 find a suitable prev_stop when we find ourselves before
16972 (reseat): Don't look for prev_stop, as that could mean a very long
16974 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16975 <cached_disp_overlay_modiff>: Cache for last found display string
16977 (compute_display_string_pos): Return the cached position if asked
16978 about the same buffer in the same area of character positions, and
16979 the buffer wasn't changed since the time the display string
16980 position was cached.
16982 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16984 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16985 is an integer, which is important for empty lines. (Bug#9149)
16987 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16989 * frame.c (Fmodify_frame_parameters): In tty case, update the
16990 default face if necessary (Bug#4238).
16992 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16994 * editfns.c (Fstring_to_char): No need to explain what a character
16995 is in the docstring (Bug#6576).
16997 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16999 * xml.c (parse_region): Make sure we always return a tree.
17001 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17003 * xml.c (parse_region): If a document contains only comments,
17006 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17008 * xml.c (make_dom): Return comments, too.
17010 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17013 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17014 and the surrounding thread.
17015 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17016 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17017 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17019 * s/openbsd.h (BROKEN_SIGIO): Define.
17020 * unexelf.c (unexec) [__OpenBSD__]:
17021 Don't update the .mdebug section of the Alpha COFF symbol table.
17023 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17025 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17028 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17030 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17031 This fixes some race conditions on the permissions of any newly
17034 * alloc.c (valid_pointer_p): Use pipe, not open.
17035 This fixes some permissions issues when debugging.
17037 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17038 If fchown fails to set both uid and gid, try to set just gid,
17039 as that is sometimes allowed. Adjust the file's mode to eliminate
17040 setuid or setgid bits that are inappropriate if fchown fails.
17042 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17044 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17045 to compare Lisp_Objects.

17050 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17052 * lread.c (read_integer): Unread even EOF character.
17053 (read1): Likewise. Properly record start position of symbol.
17055 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17056 symbol character follows.
17058 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17060 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17061 This works around a problem with the previous change to Fcopy_file.
17062 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17063 and without this change, GCC might complain about discarding
17064 fchown's return value.
17066 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17068 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17070 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17072 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17074 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17076 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17077 it's used from the C level.
17079 * process.c: Use the same condition for POLL_FOR_INPUT in both
17080 keyboard.c and process.c (bug#1858).
17082 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17084 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17085 (Fgnutls_boot): Use it.
17087 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17089 * doc.c (Fsubstitute_command_keys): Revert last change.
17091 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17093 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17094 quotes the next character, and doesn't affect other longer
17095 sequences (bug#8935).
17097 * lread.c (syms_of_lread): Clarify that is isn't only
17098 `eval-buffer' and `eval-defun' that's affected by
17099 `lexical-binding' (bug#8460).
17101 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17103 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17104 bidi redisplay when a line includes both an image and is truncated.
17106 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17108 Fix minor problems found by static checking.
17109 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17110 (elsz): Now a signed constant, not a size_t var. We prefer signed
17111 types to unsigned, to avoid integer comparison confusion. Without
17112 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17113 "cannot optimize loop, the loop counter may overflow", a symptom
17115 * indent.c (Fvertical_motion): Mark locals as initialized.
17116 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17118 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17120 * search.c (Fre_search_backward): Mention `case-fold-search' in
17121 all the re_search_* functions (bug#8138).

17141 buffer position was specified. Initialize paragraph_embedding to
17143 (reseat_to_string): Initialize the bidi iterator.
17144 (display_string): If we need to ignore text properties of
17145 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17146 original value of -1 will not work with bidi.)
17147 (compute_display_string_pos): First arg is now struct
17148 `text_pos *'; all callers changed. Support display properties on
17150 (compute_display_string_end): Support display properties on Lisp
17152 (init_iterator, reseat_1, reseat_to_string): Initialize the
17153 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17154 when iterating on a string not from display properties).
17155 (compute_display_string_pos, compute_display_string_end):
17156 Fix calculation of the object to scan. Fixes an error when using
17158 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17159 base_level_stop; instead, set base_level_stop to BEGV.
17160 Fixes crashes in vertical-motion.
17161 (next_element_from_buffer): Improve commentary for when
17162 the iterator is before prev_stop.
17163 (init_iterator): Initialize bidi_p from the default value of
17164 bidi-display-reordering, not from buffer-local value. Use the
17165 buffer-local value only if initializing for buffer iteration.
17166 (handle_invisible_prop): Support invisible properties on strings
17167 that are being bidi-reordered.
17168 (set_iterator_to_next): Support bidi reordering of C strings and

17174 Use IT_STRING_CHARPOS when displaying from a Lisp string.
17175 (init_iterator): Don't initialize it->bidi_p for strings
17177 (reseat_to_string): Initialize it->bidi_p for strings here.

17184 character that is not the first one in the visual order.
17185 (get_visually_first_element): New function, refactored from common
17186 parts of next_element_from_buffer, next_element_from_string, and
17187 next_element_from_c_string.
17188 (tool_bar_lines_needed, redisplay_tool_bar)
17189 (display_menu_bar): Force left-to-right direction. Add a FIXME
17190 comment for making that be controlled by a user option.
17191 (push_it, pop_it): Save and restore the state of the
17192 bidi iterator. Save and restore the bidi_p flag.
17193 (pop_it): Iterate out of display property for string iteration as

17196 (handle_single_display_spec): Set up it->bidi_it for iteration
17197 over a display string, and call bidi_init_it.

17199 (get_overlay_strings_1, push_display_prop): Set up the bidi
17200 iterator for displaying display or overlay strings.
17201 (forward_to_next_line_start): Don't use the shortcut if
17203 (back_to_previous_visible_line_start): If handle_display_prop
17204 pushed the iterator stack, restore the internal state of the bidi
17205 iterator by calling bidi_pop_it same number of times.
17206 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17207 and we are bidi-iterating, don't decrement the iterator position;
17208 instead, set the first_elt flag in the bidi iterator, to produce
17210 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17211 (push_display_prop): xassert that we are iterating a buffer.
17212 (push_it, pop_it): Save and restore paragraph_embedding member.
17213 (handle_single_display_spec, next_overlay_string)
17214 (get_overlay_strings_1, reseat_1, reseat_to_string)
17215 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17216 correctly. Don't assume unibyte strings are not bidi-reordered.
17217 (compute_display_string_pos)
17218 (compute_display_string_end): Fix handling the case of C string.
17219 (push_it, pop_it): Save and restore from_disp_prop_p.

17225 property. Fix a typo in popping stretch info. Add an assertion
17226 for verifying that the iterator position is in sync with the bidi
17228 (handle_single_display_spec, get_overlay_strings_1)

17253 displayed in margins. (Bug#8133) (Bug#8867)
17254 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
17256 (pos_visible_p): Support positions in bidi-reordered lines.
17257 Save and restore bidi cache.
17259 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.

17278 Support iteration over a string.
17279 (bidi_set_sor_type, bidi_resolve_explicit_1)
17280 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
17281 can now be zero (for strings); special values 0 and -1 were
17282 changed to -1 and -2, respectively.
17283 (bidi_char_at_pos): New function.
17284 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

17370 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
17372 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
17373 The old code sometimes used this field without initializing it.
17375 * alloc.c (gc_sweep): Don't read past end of array.
17376 In theory, the old code could also have corrupted Emacs internals,
17377 though it'd be very unlikely.

17640 (clone_per_buffer_values): Don't assume that

17642 This isn't true in general, and it's particularly not true
17643 if Emacs is configured with --with-wide-int.
17644 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17645 New macros, used in the buffer.c change.

17681 Random fixes. E.g., (random) never returned negative values.
17682 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17683 subseconds part to the entropy, as that's a bit more random.
17684 Prefer signed to unsigned, since the signedness doesn't matter and
17685 in general we prefer signed. When given a limit, use a
17686 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17687 latter isn't right if USE_2_TAGS_FOR_INTS.
17688 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17689 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17701 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17702 This is more efficient than Ffile_directory_p and avoids a minor race.
17704 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17706 * buffer.c (Foverlay_put): Say what the return value is
17709 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17710 is a directory before asking whether to use the file name

17713 error be more correct.
17715 * fns.c (Frequire): Remove the mention of the .gz files, since
17716 that's installation-specific, but keep the mention of

17729 Qgnutls_bootprop_verify_error (which is no longer used).
17731 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17732 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17733 Also (re)move comments that are misplaced or no longer relevant.

17762 * lread.c (syms_of_lread): Mention single symbols defined by

17795 minibuffer-local-filename-must-match-map to Elisp.
17796 (syms_of_keymap): Defsubr make-composed-keymap.
17797 * keyboard.c (menu_bar_items): Use map_keymap_canonical.
17798 (parse_menu_item): Trivial simplification.
17800 2011-07-01 Glenn Morris <rgm@gnu.org>
17802 * Makefile.in (SETTINGS_LIBS): Fix typo.
17804 2011-07-01 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)

17834 * eval.c (struct backtrace): Simplify and port the data structure.
17835 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17836 signed bit field, as this assumption is not portable and it makes
17837 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17838 "char debug_on_exit : 1" as this is not portable either; instead,
17839 use the portable "unsigned int debug_on_exit : 1". Remove unused
17840 member evalargs. Remove obsolete comments about cc bombing out.
17842 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
17844 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

17885 the overlay's window property doesn't match the current window.
17887 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.
17888 (Fwindow_hchild): Rename to Fwindow_left_child.
17889 (Fwindow_next): Rename to Fwindow_next_sibling.
17890 (Fwindow_prev): Rename to Fwindow_prev_sibling.
17891 (resize_window_check): Rename to window_resize_check.
17892 (resize_window_apply): Rename to window_resize_apply.

17910 (emacs_fixed_new): Set priv->f to argument.
17911 (emacs_fixed_get_preferred_width)
17912 (emacs_fixed_get_preferred_height): Use min_width/height from
17913 frames size_hint to set minimum and natural (Bug#8919).
17914 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17915 and use min_width/height from frames size_hint to set
17916 min_width/height (Bug#8919).
17918 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.

17936 Use gnulib's dup2 module instead of rolling our own.
17937 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

18004 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
18006 Integer and buffer overflow fixes (Bug#8873).
18008 * print.c (printchar, strout): Check for string overflow.
18009 (PRINTPREPARE, printchar, strout):
18010 Don't set size unless allocation succeeds.
18012 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18013 for sizes. Check for string overflow more accurately.
18014 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
18016 * macros.c: Integer and buffer overflow fixes.
18017 * keyboard.h (struct keyboard.kbd_macro_bufsize):
18018 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

18021 Check for size-calculation overflow.
18022 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
18024 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
18026 * lread.c: Integer overflow fixes.
18027 (read_integer): Radix is now EMACS_INT, not int,
18028 to improve quality of diagnostics for out-of-range radices.
18029 Calculate buffer size correctly for out-of-range radices.
18030 (read1): Check for integer overflow in radices, and in
18031 read-circle numbers.
18032 (read_escape): Avoid int overflow.
18033 (Fload, openp, read_buffer_size, read1)
18034 (substitute_object_recurse, read_vector, read_list, map_obarray):
18035 Use ptrdiff_t, not int, for sizes.

18050 2011-06-22 Leo Liu <sdl.web@gmail.com>
18052 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
18053 Move to minibuffer.el.
18055 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18057 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18058 The following patches are for when GLYPH_DEBUG && !XASSERT.
18059 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18060 * dispnew.c (flush_stdout):
18061 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18062 Mark as externally visible.
18063 * dispnew.c (check_window_matrix_pointers): Now static.
18064 * dispnew.c (window_to_frame_vpos):
18065 * xfns.c (unwind_create_frame):
18066 * xterm.c (x_check_font): Remove unused local.
18067 * scroll.c (CHECK_BOUNDS):
18068 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18069 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18070 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18071 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18072 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18074 (debug_method_add): Use va_list and vsprintf rather than relying
18075 on undefined behavior with wrong number of arguments.
18076 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18077 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18078 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18079 since we're not interested in debugging glyphs with old libraries.
18080 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18081 GCC 4.6.0's static checking.
18083 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18085 Integer overflow and signedness fixes (Bug#8873).
18086 A few related buffer overrun fixes, too.

18094 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
18095 (x_create_bitmap_from_xpm_data):
18096 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
18097 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
18099 * xfaces.c (load_pixmap):
18100 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
18101 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18102 (.bitmaps_last, struct x_output.icon_bitmap):
18103 Use ptrdiff_t, not int, for bitmap indexes.
18104 (x_allocate_bitmap_record): Check for size overflow.
18105 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18107 Use ptrdiff_t, not int, for overlay counts.
18108 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18109 * editfns.c (overlays_around, get_pos_property):
18110 * textprop.c (get_char_property_and_overlay):
18111 * xdisp.c (next_overlay_change, note_mouse_highlight):
18112 * xfaces.c (face_at_buffer_position):
18113 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18114 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18115 (Fnext_overlay_change, Fprevious_overlay_change)
18116 (mouse_face_overlay_overlaps, Foverlays_in):
18117 Use ptrdiff_t, not int, for sizes.
18118 (overlays_at, overlays_in): Check for size-calculation overflow.
18120 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18122 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18123 (x_session_initialize): Do not assume string length fits in int.
18125 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18126 This is unlikely, but can occur if DPI is outlandish.
18128 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18129 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18131 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18132 * xrdb.c (magic_file_p, search_magic_path):
18133 Omit last arg SUFFIX; it was always 0. All callers changed.
18134 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18136 * xfont.c (xfont_match): Avoid need for strlen.
18138 * xfns.c: Don't assume strlen fits in int.
18139 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18141 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18142 not unsigned long, as we prefer signed integers. All callers changed.
18143 Detect integer overflow in repeat count.
18144 (message_dolog): Don't assume print length fits in 39 bytes.
18145 (display_mode_element): Don't assume strlen fits in int.
18147 * termcap.c: Don't assume sizes fit in int and never overflow.
18148 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18149 (gobble_line): Check for size-calculation overflow.
18151 * minibuf.c (Fread_buffer):
18152 * lread.c (intern, intern_c_string):
18153 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18154 Don't assume string length fits in int.
18156 * keyboard.c (parse_tool_bar_item):
18157 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18159 * font.c: Don't assume string length fits in int.
18160 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18161 Use ptrdiff_t, not int.
18162 (font_intern_prop): Don't assume string length fits in int.
18163 Don't assume integer property fits in fixnum.
18164 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18166 * filelock.c: Fix some buffer overrun and integer overflow issues.
18167 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18168 Reformulate so as not to need the command string.
18169 Invoke gzip -cd rather than gunzip, as it's more portable.
18170 (lock_info_type, lock_file_1, lock_file):
18171 Don't assume pid_t and time_t fit in unsigned long.
18172 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18173 (current_lock_owner): Prefer signed type for sizes.
18174 Use memcpy, not strncpy, where memcpy is what is really wanted.
18175 Don't assume (via atoi) that time_t and pid_t fit in int.
18176 Check for time_t and/or pid_t out of range, e.g., via a network share.
18177 Don't alloca where an auto var works fine.
18179 * fileio.c: Fix some integer overflow issues.
18180 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18181 Don't assume string length fits in int.
18182 (directory_file_name): Don't assume string length fits in long.
18183 (make_temp_name): Don't assume pid fits in int, or that its print
18184 length is less than 20.
18186 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18188 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18190 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18192 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18193 We prefer signed integers, even for size calculations.
18195 * emacs.c: Don't assume string length fits in 'int'.
18196 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18197 (main): Don't invoke strlen when not needed.
18199 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18200 (XD_DEBUG_MESSAGE): Don't waste a byte.
18202 * callproc.c (getenv_internal_1, getenv_internal)
18203 (Fgetenv_internal):
18204 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18206 * lread.c (invalid_syntax): Omit length argument.
18207 All uses changed. This doesn't fix a bug, but it simplifies the
18208 code away from its former Hollerith-constant appearance, and it's
18209 one less 'int' to worry about when looking at integer-overflow issues.
18210 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18212 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18213 This didn't break anything, but it didn't help either.
18214 It's confusing to put a bogus integer in a place where the actual
18215 value does not matter.
18216 (LIST_END_P): Remove unused macro and its bogus comment.
18217 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18219 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18220 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18222 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18223 We prefer signed types, and the value cannot exceed the EMACS_INT
18224 range anyway (because otherwise the length would not be representable).
18225 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18226 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18227 This avoids a GCC warning when WIDE_EMACS_INT.
18229 * indent.c (sane_tab_width): New function.
18230 (current_column, scan_for_column, Findent_to, position_indentation)
18231 (compute_motion): Use it. This is just for clarity.
18232 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18234 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18236 * lisp.h (lint_assume): New macro.
18237 * composite.c (composition_gstring_put_cache):
18238 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18240 * editfns.c, insdel.c:
18241 Omit unnecessary forward decls, to simplify future changes.
18243 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18245 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18247 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18248 Use much-faster test for byte-length change.
18249 Don't assume string byte-length fits in 'int'.
18250 Check that character arg fits in 'int'.
18251 (mapcar1): Declare byte as byte, for clarity.
18253 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18255 * fns.c (concat): Catch string overflow earlier.
18256 Do not rely on integer wraparound.
18258 * dispextern.h (struct it.overlay_strings_charpos)
18259 (struct it.selective): Now EMACS_INT, not int.
18260 * xdisp.c (forward_to_next_line_start)
18261 (back_to_previous_visible_line_start)
18262 (reseat_at_next_visible_line_start, next_element_from_buffer):
18263 Don't arbitrarily truncate the value of 'selective' to int.
18265 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18267 * composite.c: Don't truncate sizes to 'int'.
18268 (composition_gstring_p, composition_reseat_it)
18269 (composition_adjust_point): Use EMACS_INT, not int.
18270 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18271 not EMACS_UINT, for indexes.
18273 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18275 * buffer.c: Include <verify.h>.
18276 (struct sortvec.priority, struct sortstr.priority):
18277 Now EMACS_INT, not int.
18278 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18279 (struct sortstr.size, record_overlay_string)
18280 (struct sortstrlist.size, struct sortlist.used):
18281 Don't truncate size to int.
18282 (record_overlay_string): Check for size-calculation overflow.
18283 (init_buffer_once): Check at compile-time, not run-time.
18285 2011-06-22 Jim Meyering <meyering@redhat.com>
18287 Don't leak an XBM-image-sized buffer
18288 * image.c (xbm_load): Free the image buffer after using it.
18290 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18293 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18294 that Sun C diagnosed.
18295 * fns.c (secure_hash): Fix pointer signedness issue.
18296 * intervals.c (static_offset_intervals): New function.
18297 (offset_intervals): Use it.
18299 2011-06-21 Leo Liu <sdl.web@gmail.com>
18302 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18305 * fns.c (secure_hash): Rename from crypto_hash_function and change
18306 the first arg to accept symbols.
18307 (Fsecure_hash): New primitive.
18308 (syms_of_fns): New symbols.
18310 2011-06-20 Deniz Dogan <deniz@dogan.se>
18312 * process.c (Fset_process_buffer): Clarify return value in
18315 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18317 * dispnew.c (add_window_display_history): Use BVAR.
18319 * xdisp.c (debug_method_add): Use BVAR.
18320 (check_window_end, dump_glyph_matrix, dump_glyph)
18321 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18323 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18326 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18327 check till after the cache is created in init_frame_faces.
18329 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18331 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18333 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18335 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18336 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18337 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18339 Improve buffer-overflow checking (Bug#8873).
18340 * fileio.c (Finsert_file_contents):
18341 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18342 Remove the old (too-loose) buffer overflow checks.
18343 They weren't needed, since make_gap checks for buffer overflow.
18344 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18345 The old code merely checked for Emacs fixnum overflow, and relied
18346 on undefined (wraparound) behavior. The new code avoids undefined
18347 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18349 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18350 Tune. Don't use wider integers than needed. Don't use alloca.
18351 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18353 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18355 * insdel.c, lisp.h (buffer_overflow): New function.
18356 (insert_from_buffer_1, replace_range, replace_range_2):
18357 * insdel.c (make_gap_larger):
18358 * editfns.c (Finsert_char):
18359 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18361 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18363 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18365 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18367 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18368 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18370 * fileio.c: Don't assume EMACS_INT fits in off_t.
18371 (emacs_lseek): New static function.
18372 (Finsert_file_contents, Fwrite_region): Use it.
18373 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18375 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18377 * fns.c: Don't overflow int when computing a list length.
18378 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18379 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18380 truncation on 64-bit hosts. Check for QUIT every
18381 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18382 faster and is responsive enough.
18383 (Flength): Report an error instead of overflowing an integer.
18384 (Fsafe_length): Return a float if the value is not representable
18385 as a fixnum. This shouldn't happen except in contrived situations.
18386 (Fnthcdr, Fsort): Don't assume list length fits in int.
18387 (Fcopy_sequence): Don't assume vector length fits in int.
18389 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18390 (header_size, word_size): New constants.
18391 (allocate_vectorlike): Don't check size overflow here.
18392 (allocate_vector): Check it here instead, since this is the only
18393 caller of allocate_vectorlike that could cause overflow.
18394 Check that the new vector's length is representable as a fixnum.
18396 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18397 The previous code was bogus. For example, next_almost_prime (32)
18398 returned 39, which is undesirable as it is a multiple of 3; and
18399 next_almost_prime (24) returned 25, which is a multiple of 5 so
18400 why was the code bothering to check for multiples of 7?
18402 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18404 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18406 Variadic C functions now count arguments with ptrdiff_t.
18407 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18408 Back then I didn't know that the Emacs coding style prefers signed int.
18409 Also, in the meantime I found a few more instances where arguments
18410 were being counted with int, which may truncate counts on 64-bit
18411 machines, or EMACS_INT, which may be unnecessarily wide.
18412 * lisp.h (struct Lisp_Subr.function.aMANY)
18413 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18414 Arg counts are now ptrdiff_t, not size_t.
18415 All variadic functions and their callers changed accordingly.
18416 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18417 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18418 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18419 * callint.c (Fcall_interactively): Check arg count for overflow,
18420 to avoid potential buffer overrun. Use signed char, not 'int',
18421 for 'varies' array, so that we needn't bother to check its size
18422 calculation for overflow.
18423 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18424 * eval.c (apply_lambda):
18425 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18426 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18427 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18429 * callint.c (Fcall_interactively): Don't use index var as event count.
18431 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18432 * mem-limits.h (SIZE): Remove; no longer used.
18434 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18436 Remove unnecessary casts.
18437 * xterm.c (x_term_init):
18438 * xfns.c (x_set_border_pixel):
18439 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18440 These aren't needed now that we assume ANSI C.
18442 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18443 It's more likely to cause problems (due to unsigned overflow)
18446 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18448 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18450 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18452 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18454 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18456 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18458 GLYPH_CODE_FACE returns EMACS_INT, not int.
18459 * dispextern.h (merge_faces):
18460 * xfaces.c (merge_faces):
18461 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18462 Don't assume EMACS_INT fits in int.
18464 * character.h (CHAR_VALID_P): Remove unused parameter.
18465 * fontset.c, lisp.h, xdisp.c: All uses changed.
18467 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18469 * fns.c (concat): Minor tuning based on overflow analysis.
18470 This doesn't fix any bugs. Use int to hold character, instead
18471 of constantly refetching from Emacs object. Use XFASTINT, not
18472 XINT, for value known to be a character. Don't bother comparing
18473 a single byte to 0400, as it's always less.
18475 * floatfns.c (Fexpt):
18476 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18478 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18481 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18483 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18484 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18485 incorrectly succeed when S was a string, because 4294967386 was
18486 truncated before it was used.
18488 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18489 Otherwise, an out-of-range integer could cause undefined behavior
18492 * composite.c: Use int, not EMACS_INT, for characters.
18493 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18494 EMACS_INT, for values that are known to be in character range.
18495 This doesn't fix any bugs but is the usual style inside Emacs and
18496 may generate better code on 32-bit machines.
18498 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18499 This is for reasons similar to the recent CHAR_STRING fix.
18500 * charset.c (Fencode_char): Check that character arg is actually
18501 a character. Pass an int to ENCODE_CHAR.
18502 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18503 wider than 'int', as a compile-time check to prevent future regressions
18506 * character.c (char_string): Remove unnecessary casts.
18508 Make sure a 64-bit char is never passed to CHAR_STRING.
18509 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18510 by silently ignoring the top 32 bits, allowing some values
18511 that were far too large to be valid characters.
18512 * character.h: Include <verify.h>.
18513 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18514 arguments are no wider than unsigned, as a compile-time check
18515 to prevent future regressions in this area.
18517 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18518 (Fsubst_char_in_region):
18520 * xdisp.c (decode_mode_spec_coding):
18521 Adjust to CHAR_STRING's new requirement.
18522 * editfns.c (Finsert_char, Fsubst_char_in_region):
18523 * fns.c (concat): Check that character args are actually
18524 characters. Without this test, these functions did the wrong
18525 thing with wildly out-of-range values on 64-bit hosts.
18527 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18528 These casts should not be needed on 32-bit hosts, either.
18529 * keyboard.c (read_char):
18530 * lread.c (Fload): Remove casts to unsigned.
18532 * lisp.h (UNSIGNED_CMP): New macro.
18533 This fixes comparison bugs on 64-bit hosts.
18534 (ASCII_CHAR_P): Use it.
18535 * casefiddle.c (casify_object):
18536 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18537 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18538 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18539 * dispextern.h (FACE_FROM_ID):
18540 * keyboard.c (read_char): Use UNSIGNED_CMP.
18542 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18543 not to EMACS_INT, to avoid GCC warning.
18545 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18547 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18548 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18549 isn't needed on 32-bit machines.
18551 * buffer.c (Fgenerate_new_buffer_name):
18552 Use EMACS_INT for count, not int.
18553 (advance_to_char_boundary): Return EMACS_INT, not int.
18555 * data.c (Qcompiled_function): Now static.
18557 * window.c (window_body_lines): Now static.
18559 * image.c (gif_load): Rename local to avoid shadowing.
18561 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18562 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18563 * alloc.c (make_save_value): Integer argument is now of type
18564 ptrdiff_t, not int.
18565 (mark_object): Use ptrdiff_t, not int.
18566 * lisp.h (pD): New macro.
18567 * print.c (print_object): Use it.
18569 * alloc.c: Use EMACS_INT, not int, to count objects.
18570 (total_conses, total_markers, total_symbols, total_vector_size)
18571 (total_free_conses, total_free_markers, total_free_symbols)
18572 (total_free_floats, total_floats, total_free_intervals)
18573 (total_intervals, total_strings, total_free_strings):
18574 Now EMACS_INT, not int. All uses changed.
18575 (Fgarbage_collect): Compute overall total using a double, so that
18576 integer overflow is less likely to be a problem. Check for overflow
18577 when converting back to an integer.
18578 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18579 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18580 These were 'int' variables that could overflow on 64-bit hosts;
18581 they were never used, so remove them instead of repairing them.
18582 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18583 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18584 Previously, this ceilinged at INT_MAX, but that doesn't work on
18586 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18588 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18589 (allocate_vectorlike): Check for ptrdiff_t overflow.
18590 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18591 when a (possibly-narrower) signed value would do just as well.
18592 We prefer using signed arithmetic, to avoid comparison confusion.
18594 * alloc.c: Catch some string size overflows that we were missing.
18595 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18596 for convenience in STRING_BYTES_MAX.
18597 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18598 The definition here is exact; the one in lisp.h was approximate.
18599 (allocate_string_data): Check for string overflow. This catches
18600 some instances we weren't catching before. Also, it catches
18601 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18602 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18603 and ptrdiff_t and EMACS_INT are both 64 bits.
18605 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18606 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18607 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18609 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18611 * alloc.c (Fmake_string): Check for out-of-range init.
18613 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18615 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18617 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18619 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18620 xg_get_default_scrollbar_width.
18622 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18623 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18624 (style_changed_cb): Call update_theme_scrollbar_width and call
18625 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18626 all frames (Bug#8505).
18627 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18628 Call gtk_window_set_resizable if HAVE_GTK3.
18629 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18630 and height if HAVE_GTK3 (Bug#8505).
18631 (scroll_bar_width_for_theme): New variable.
18632 (update_theme_scrollbar_width): New function.
18633 (xg_get_default_scrollbar_width): Move code to
18634 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18635 (xg_initialize): Call update_theme_scrollbar_width.
18637 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18639 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18641 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18643 * frame.c (make_frame): Call other_buffer_safely instead of
18646 * window.c (temp_output_buffer_show): Call display_buffer with
18647 second argument Vtemp_buffer_show_specifiers and reset latter
18648 immediately after the call.
18649 (Vtemp_buffer_show_specifiers): New variable.
18650 (auto_window_vscroll_p, next_screen_context_lines)
18651 (Vscroll_preserve_screen_position): Remove leading asterisks from
18654 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18656 Fix minor problems found by GCC 4.6.0 static checking.
18657 * buffer.c (Qclone_number): Remove for now, as it's unused.
18658 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18659 (record_buffer): Remove unused local.
18660 * frame.c (other_visible_frames, frame_buffer_list): Now static.
18661 (set_frame_buffer_list): Remove; unused.
18662 * frame.h (other_visible_frames): Remove decl.
18663 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
18664 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
18665 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
18667 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
18668 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):

19145 New error handlers.
19146 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
19147 Obey Vx_select_enable_clipboard_manager. Catch errors in
19148 x_clipboard_manager_save (Bug#8779).
19149 (Vx_select_enable_clipboard_manager): New variable.
19150 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
19152 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
19154 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
19156 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19158 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
19159 in the current matrix if keep_current_p is non-zero.

19163 * bidi.c (bidi_level_of_next_char): Fix last change.
19165 2011-06-03 Eli Zaretskii <eliz@gnu.org>
19167 Support bidi reordering of text covered by display properties.
19169 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
19170 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
19171 (bidi_cache_search, bidi_cache_iterator_state)
19172 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
19173 (bidi_level_of_next_char, bidi_move_to_visually_next):
19174 Support character positions inside a run of characters covered by a
19176 (bidi_paragraph_init, bidi_resolve_explicit_1)
19177 (bidi_level_of_next_char): Call bidi_fetch_char and
19178 bidi_fetch_char_advance instead of FETCH_CHAR and
19179 FETCH_CHAR_ADVANCE.

19181 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
19183 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
19184 instead of using explicit *_CHAR codes.
19185 (bidi_resolve_explicit, bidi_resolve_weak):
19186 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
19187 bidirectional text is supported only in multibyte buffers.
19188 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
19189 it to initialize the frame_window_p member of struct bidi_it.
19190 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
19191 (bidi_resolve_explicit, bidi_resolve_weak)

19193 bidi_it->nchars is non-positive.
19194 (bidi_level_of_next_char): Don't try to lookup the cache for the
19195 next/previous character if nothing is cached there yet, or if we
19196 were just reseat()'ed to a new position.
19198 * xdisp.c (set_cursor_from_row): Set start and stop points
19199 according to the row's direction when priming the loop that looks
19200 for the glyph on which to display cursor.
19201 (single_display_spec_intangible_p): Function deleted.
19202 (display_prop_intangible_p): Reimplement to call
19203 handle_display_spec instead of single_display_spec_intangible_p.
19204 Accept 3 additional arguments needed by handle_display_spec.
19205 This fixes incorrect cursor motion across display property with complex
19206 values: lists, `(when COND...)' forms, etc.
19207 (single_display_spec_string_p): Support property values that are
19208 lists with the argument STRING its top-level element.
19209 (display_prop_string_p): Fix the condition for processing a
19210 property that is a list to be consistent with handle_display_spec.
19211 (handle_display_spec): New function, refactored from the
19212 last portion of handle_display_prop.
19213 (compute_display_string_pos): Accept additional argument
19214 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19215 value of a `display' property is a "replacing spec".
19216 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19217 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19218 the display property, but just return a value indicating whether
19219 the display property will replace the characters it covers.
19220 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19221 frame_window_p members of struct bidi_it.
19222 (compute_display_string_pos, compute_display_string_end):
19224 (push_it): Accept second argument POSITION, where pop_it should
19225 jump to continue iteration.
19226 (reseat_1): Initialize bidi_it.disp_pos.
19228 * keyboard.c (adjust_point_for_property): Adjust the call to
19229 display_prop_intangible_p to its new signature.
19231 * dispextern.h (struct bidi_it): New member frame_window_p.
19232 (bidi_init_it): Update prototypes.
19233 (display_prop_intangible_p): Update prototype.
19234 (compute_display_string_pos, compute_display_string_end):
19235 Declare prototypes.
19236 (struct bidi_it): New members nchars and disp_pos. ch_len is now
19239 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
19241 Malloc failure behavior now depends on size of allocation.
19242 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19243 * lisp.h: Change signatures accordingly.
19244 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19245 All callers changed. (Bug#8762)
19247 * gnutls.c: Use Emacs's memory allocators.
19248 Without this change, the gnutls library would invoke malloc etc.
19249 directly, which causes problems on non-SYNC_INPUT hosts, and which
19250 runs afoul of improving memory_full behavior. (Bug#8761)
19251 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19252 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19253 xfree instead of the default malloc, realloc, free.
19254 (Fgnutls_boot): No need to check for memory allocation failure,
19255 since xmalloc does that for us.
19257 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19258 * category.c (hash_get_category_set):
19259 * ccl.c (ccl_driver):
19260 * charset.c (Fdefine_charset_internal):

19270 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
19271 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
19272 (Fsxhash, Fgethash, Fputhash, Fmaphash):
19273 * image.c (make_image, search_image_cache, lookup_image)
19274 (xpm_put_color_table_h):
19275 * lisp.h (struct Lisp_Hash_Table):
19276 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19277 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19278 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19279 * alloc.c (allocate_vectorlike):
19280 Check for overflow in vector size calculations.
19281 * ccl.c (ccl_driver):
19282 Check for overflow when converting EMACS_INT to int.
19283 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19284 need to be updated by these changes.
19285 * fns.c (make_hash_table, maybe_resize_hash_table):
19286 Check for integer overflow with large hash tables.
19287 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19288 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19289 (SXHASH_REDUCE): New macro.
19290 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19291 Use it instead of discarding useful hash info with large hash values.
19292 (sxhash_float): New function.
19293 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19294 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19295 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19296 Rewrite to use FIXNUM_BITS, as this simplifies things.
19297 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19298 Adjust signatures to match updated version of code.
19299 (consing_since_gc): Now EMACS_INT, since a single hash table can
19300 use more than INT_MAX bytes.
19302 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19304 Make it possible to build with GCC-4.6+ -O2 -flto.
19306 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19308 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19310 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19311 Call minibuffer-inactive-mode.
19313 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19315 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19316 Update dependencies.
19318 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19320 * data.c (init_data): Remove code for UTS, this system is not
19323 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19325 Don't force ./temacs to start in terminal mode.
19327 * frame.c (make_initial_frame): Initialize faces in all cases, not
19328 only when CANNOT_DUMP is defined.
19329 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19331 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19333 * dispnew.c (add_window_display_history): Use const for the string
19334 pointer. Remove declaration, not needed.
19336 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19338 Use 'inline', not 'INLINE'.
19339 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19340 * alloc.c, fontset.c (INLINE): Remove.
19341 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19342 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19343 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19344 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19345 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19347 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19349 Make it possible to run ./temacs.
19351 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19352 syms_of_callproc does the same thing. Remove test for
19353 "initialized", do it in the caller.
19354 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19356 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19358 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19359 (read_minibuf): Use get_minibuffer.
19360 (syms_of_minibuf): Use DEFSYM.
19361 (Qmetadata): New var.
19362 * data.c (Qbuffer): Don't make it static.
19363 (syms_of_data): Use DEFSYM.
19365 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19367 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19368 (CCL_CODE_MIN): New macro.
19370 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19372 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19374 * eval.c (Qdebug): Now static.
19375 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19376 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19377 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19379 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19381 * image.c: Various fixes to ImageMagick code comments.
19382 (Fimagemagick_types): Doc fix.
19384 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19386 Minor fixes prompted by GCC 4.6.0 warnings.
19388 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19390 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19391 (x_clipboard_manager_save_all): Move extern decl to ...
19392 * xterm.h: ... here, so that it can be checked for consistency.
19394 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19396 * xselect.c (x_clipboard_manager_save_frame)
19397 (x_clipboard_manager_save_all): New functions.
19398 (Fx_clipboard_manager_save): Lisp function deleted.
19400 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19401 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19403 * xterm.h: Update prototype.
19405 2011-05-28 William Xu <william.xwl@gmail.com>
19407 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19408 exiting (Bug#8239).
19410 2011-05-28 Jim Meyering <meyering@redhat.com>
19412 Avoid a sign-extension bug in crypto_hash_function.
19413 * fns.c (to_uchar): Define.
19414 (crypto_hash_function): Use it to convert some newly-signed
19415 variables to unsigned, to avoid sign-extension bugs. For example,
19416 without this change, (md5 "truc") would evaluate to
19417 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19418 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19419 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19421 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19423 Integer overflow fixes.
19425 * dbusbind.c: Serial number integer overflow fixes.
19426 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19427 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19428 to hold a serial number that is too large for a fixnum.
19429 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19430 Check for serial numbers out of range. Decode any serial number
19431 that was so large that it became a float. (Bug#8722)
19433 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19434 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19435 Use XFASTINT rather than XUINT when numbers are nonnegative.
19436 (xd_append_arg, Fdbus_method_return_internal):
19437 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19438 arguments, check that Lisp number is nonnegative, rather than
19439 silently wrapping negative numbers around. (Bug#8722)
19440 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19443 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19445 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19447 ccl: Add integer overflow checks.
19448 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19449 (IN_INT_RANGE): New macros.
19450 (ccl_driver): Use them to check for integer overflow when
19451 decoding a CCL program. Many of the new checks are whether XINT (x)
19452 fits in int; it doesn't always, on 64-bit hosts. The new version
19453 doesn't catch all possible integer overflows, but it's an
19454 improvement. (Bug#8719)
19456 * alloc.c (make_event_array): Use XINT, not XUINT.
19457 There's no need for unsigned here.
19459 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19460 This follows up to the 2011-05-06 change that substituted uintptr_t
19461 for EMACS_INT. This case wasn't caught back then.
19463 Rework Fformat to avoid integer overflow issues.
19464 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19465 now (part of C89). Include <verify.h>.
19466 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19467 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19468 (Fformat): Avoid the prepass trying to compute sizes; it was only
19469 approximate and thus did not catch overflow reliably. Instead, walk
19470 through the format just once, formatting and computing sizes as we go,
19471 checking for integer overflow at every step, and allocating a larger
19472 buffer as needed. Keep track separately whether the format is
19473 multibyte. Keep only the most-recently calculated precision, rather
19474 than them all. Record whether each argument has been converted to
19475 string. Use EMACS_INT, not int, for byte and char and arg counts.
19476 Support field widths and precisions larger than INT_MAX. Avoid
19477 sprintf's undefined behavior with conversion specifications such as %#d
19478 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19479 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19480 formatting out-of-range floating point numbers with int
19481 formats. (Bug#8668)
19483 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19485 * data.c: Avoid integer truncation in expressions involving floats.
19486 * data.c: Include <intprops.h>.
19487 (arith_driver): When there's an integer overflow in an expression
19488 involving floating point, convert the integers to floating point
19489 so that the resulting value does not suffer from catastrophic
19490 integer truncation. For example, on a 64-bit host (* 4
19491 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19492 Do not rely on undefined behavior after integer overflow.
19494 merge count_size_as_multibyte, parse_str_to_multibyte
19495 * character.c, character.h (count_size_as_multibyte):
19496 Rename from parse_str_to_multibyte; all uses changed.
19497 Check for integer overflow.
19498 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19499 since it's now a duplicate of the other. This is more of
19500 a character than a buffer op, so better that it's in character.c.
19501 * fns.c, print.c: Adjust to above changes.
19503 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19505 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19507 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19509 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19510 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19511 (x_clipboard_manager_save): Now static.
19512 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19514 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19515 (crypto_hash_function): Now static.
19516 Fix pointer signedness problems. Avoid unnecessary initializations.
19518 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19520 * termhooks.h (Vselection_alist): Make it terminal-local.
19522 * terminal.c (create_terminal): Initialize it.
19524 * xselect.c: Support for clipboard managers.
19525 (Vselection_alist): Move to termhooks.h as terminal-local var.
19526 (LOCAL_SELECTION): New macro.
19527 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19528 (symbol_to_x_atom): Remove gratuitous arg.
19529 (x_handle_selection_request, lisp_data_to_selection_data)
19530 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19531 (x_own_selection, x_get_local_selection, x_convert_selection):
19532 New arg, specifying work frame. Use terminal-local Vselection_alist.
19533 (some_frame_on_display): Delete unused function.
19534 (Fx_own_selection_internal, Fx_get_selection_internal)
19535 (Fx_disown_selection_internal, Fx_selection_owner_p)
19536 (Fx_selection_exists_p): New optional frame arg.
19537 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19538 (x_handle_selection_clear): Don't treat other terminals with the
19539 same keyboard specially. Use the terminal-local Vselection_alist.
19540 (x_clear_frame_selections): Use Frun_hook_with_args.
19542 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19544 * xterm.h: Add support for those atoms.
19546 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19548 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19549 (converted_selections, conversion_fail_tag): New global variables.
19550 (x_selection_request_lisp_error): Free the above.
19551 (x_get_local_selection): Remove unnecessary code.
19552 (x_reply_selection_request): Args changed; handle arbitrary array
19553 of converted selections stored in converted_selections.
19554 Separate the XChangeProperty and SelectionNotify steps.
19555 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19556 (x_convert_selection): New function.
19557 (x_handle_selection_event): Simplify.
19558 (x_get_foreign_selection): Don't ignore incoming requests while
19559 waiting for an answer; this will fail when we implement
19560 SAVE_TARGETS, and seems unnecessary anyway.
19561 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19562 (Vx_sent_selection_functions): Doc fix.
19564 2011-05-26 Leo Liu <sdl.web@gmail.com>
19566 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19568 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19570 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19572 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19573 for fringe update if it has periodic bitmap.
19574 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19575 and fringe_bitmap_periodic_p.
19577 * fringe.c (get_fringe_bitmap_data): New function.
19578 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19579 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19580 row. Mark glyph row for fringe update if periodicity changed.
19582 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19583 for fringe update unless it has periodic bitmap.
19585 2011-05-25 Kenichi Handa <handa@m17n.org>
19587 * xdisp.c (get_next_display_element): Set correct it->face_id for
19588 a static composition.
19590 2011-05-24 Leo Liu <sdl.web@gmail.com>
19593 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19595 * fns.c (crypto_hash_function, Fsha1): New function.
19596 (Fmd5): Use crypto_hash_function.
19597 (syms_of_fns): Add Ssha1.
19599 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19601 * gnutls.c: Remove unused macros.
19602 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19603 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19604 Remove macros that are defined and never used.
19605 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19607 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19609 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19610 (Fx_get_selection_internal): Minor cleanup.
19611 (Fx_own_selection_internal): Rename arguments for consistency with
19614 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19616 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19618 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19620 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19622 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19624 * dispnew.c (scrolling_window): Don't exclude the case that the
19625 last enabled row in the desired matrix touches the bottom boundary.
19627 2011-05-21 Glenn Morris <rgm@gnu.org>
19629 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19630 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19631 and add some more files.
19633 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19635 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19636 report_file_error introduced by the change from 2011-05-07.
19638 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19640 * systime.h (Time): Define only if emacs is defined.
19641 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19642 where the include path doesn't have X11/X.h by default. See
19643 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19645 2011-05-20 Kenichi Handa <handa@m17n.org>
19647 * composite.c (find_automatic_composition): Fix previous change.
19649 2011-05-20 Glenn Morris <rgm@gnu.org>
19651 * lisp.mk: New file, split from Makefile.in.
19652 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19653 (shortlisp): Remove.
19654 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19656 2011-05-19 Glenn Morris <rgm@gnu.org>
19658 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19659 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19660 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19661 (lisp): Set the order to that of loadup.el.
19662 (shortlisp): Make it a copy of $lisp.
19663 (SOME_MACHINE_LISP): Remove.
19664 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19665 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19667 2011-05-18 Kenichi Handa <handa@m17n.org>
19669 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19670 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19671 (find_automatic_composition): Mostly rewrite for efficiency.
19673 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19675 * makefile.w32-in: Update dependencies.
19677 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19679 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19680 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19682 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19684 Fix some integer overflow issues, such as string length overflow.
19686 * insdel.c (count_size_as_multibyte): Check for string overflow.
19688 * character.c (lisp_string_width): Check for string overflow.
19689 Use EMACS_INT, not int, for string indexes and lengths; in
19690 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19691 the resulting string length overflows an EMACS_INT; instead,
19692 report a string overflow if no precision given. When checking for
19693 precision exhaustion, use a check that cannot possibly have
19694 integer overflow. (Bug#8675)
19695 * character.h (lisp_string_width): Adjust to new signature.
19697 * alloc.c (string_overflow): New function.
19698 (Fmake_string): Use it. This doesn't change behavior, but saves
19699 a few bytes and will simplify future changes.
19700 * character.c (string_escape_byte8): Likewise.
19701 * lisp.h (string_overflow): New decl.
19703 Fixups, following up to the user-interface timestamp change.
19704 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19705 for UI timestamps, instead of unsigned long.
19706 * msdos.c (mouse_get_pos): Likewise.
19707 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19708 * w32gui.h (Time): Define by including "systime.h" rather than by
19709 declaring it ourselves. (Bug#8664)
19711 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19712 * image.c (clear_image_cache): Likewise.
19714 * term.c (term_mouse_position): Don't assume time_t wraparound.
19716 Be more systematic about user-interface timestamps.
19717 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19718 and sometimes 'EMACS_UINT', to represent these timestamps.
19719 This change causes it to use 'Time' uniformly, as that's what X uses.
19720 This makes the code easier to follow, and makes it easier to catch
19721 integer overflow bugs such as Bug#8664.
19722 * frame.c (Fmouse_position, Fmouse_pixel_position):
19723 Use Time, not unsigned long, for user-interface timestamps.
19724 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19725 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19726 * keyboard.h (last_event_timestamp): Likewise.
19727 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19728 * menu.h (xmenu_show): Likewise.
19729 * term.c (term_mouse_position): Likewise.
19730 * termhooks.h (struct input_event.timestamp): Likewise.
19731 (struct terminal.mouse_position_hook): Likewise.
19732 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19733 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19734 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19735 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19736 what it was before.
19737 * menu.h, termhooks.h: Include "systime.h", for Time.
19739 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19740 Don't assume that the difference between two unsigned long values
19741 can fit into an integer. At this point, we know button_down_time
19742 <= event->timestamp, so the difference must be nonnegative, so
19743 there's no need to cast the result if double-click-time is
19744 nonnegative, as it should be; check that it's nonnegative, just in
19745 case. This bug is triggered when events are more than 2**31 ms
19746 apart (about 25 days). (Bug#8664)
19748 * xselect.c (last_event_timestamp): Remove duplicate decl.
19749 (x_own_selection): Remove needless cast to unsigned long.
19751 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19752 that always fit in int. Use a sentinel instead of a counter, to
19753 avoid a temp and to allay GCC's concerns about possible int overflow.
19754 * frame.h (struct frame): Use int for menu_bar_items_used
19755 instead of EMACS_INT, since it always fits in int.
19757 * menu.c (grow_menu_items): Check for int overflow.
19759 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19761 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19762 Before, the code was not consistent. These values cannot exceed
19763 2**31 - 1 so there's no need to make them unsigned.
19764 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19765 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19766 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19768 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19770 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19771 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19772 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19773 presumably because the widths might not match.
19775 * window.c (size_window): Avoid needless test at loop start.
19777 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19779 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19781 2011-05-12 Drew Adams <drew.adams@oracle.com>
19783 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19785 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19787 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19788 `width' to `bar_area_x' and `bar_area_width', respectively.
19789 (x_scroll_run): Take account of fringe background extension.
19791 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19792 Rename local vars `left' and `width' to `bar_area_x' and
19793 `bar_area_width', respectively.
19794 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19795 background extension.
19797 2011-05-10 Jim Meyering <meyering@redhat.com>
19799 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19801 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19803 * image.c (Finit_image_library): Return t for built-in image types,
19804 like pbm and xbm. (Bug#8640)
19806 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19808 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19810 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19812 * w32console.c (Fset_screen_color): Doc fix.
19813 (Fget_screen_color): New function.
19814 (syms_of_ntterm): Defsubr it.
19816 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19817 unlink the temporary file if Fcall_process didn't create it in the
19819 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19820 child process will be redirected to a file specified with `:file'.
19821 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19822 cue to call_process_cleanup not to close that handle.
19824 2011-05-07 Ben Key <bkey76@gmail.com>
19826 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19827 one of two shell specific rules, either bootstrap-temacs-CMD or
19828 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19829 to the previous implementation of the bootstrap-temacs rule.
19830 The bootstrap-temacs-CMD rule is similar to the previous
19831 implementation of the bootstrap-temacs rule except that it
19832 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19835 These changes, along with some changes to nt/configure.bat,
19836 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19837 earlier fix to add support for --cflags and --ldflags options
19838 that include quotes so that it works whether make uses cmd or
19841 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19843 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19844 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19846 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19847 a string. Handle both cases.
19848 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19849 (Fdbus_register_method): Use Qinvalid_function.
19851 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19853 * makefile.w32-in: Update dependencies.
19854 (LISP_H): Add inttypes.h and stdin.h.
19855 (PROCESS_H): Add unistd.h.
19857 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19859 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19860 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19862 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19864 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19866 * term.c (vfatal): Remove stray call to va_end.
19867 It's not needed and the C Standard doesn't allow it here anyway.
19869 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19870 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19872 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19875 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19877 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19879 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19881 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19883 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19885 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19886 * charset.c (Fdefine_charset_internal): Don't initialize
19887 charset.code_space[15]. The value was garbage, on hosts with
19888 32-bit int (Bug#8600).
19890 * lread.c (read_integer): Be more consistent with string-to-number.
19891 Use string_to_number to do the actual conversion; this avoids
19892 rounding errors and fixes some other screwups. Without this fix,
19893 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19894 (digit_to_number): Move earlier, for benefit of read_integer.
19895 Return -1 if the digit is out of range for the base, -2 if it is
19896 not a digit in any supported base. (Bug#8602)
19898 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19900 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19901 to match comment at start of function. This also removes a
19902 GCC warning about overflow in a 32+64-bit port.
19904 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19906 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19907 Reported by Stefan Monnier in
19908 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19909 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19910 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19912 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19913 (EMACS_UINTPTR): Likewise, with uintptr_t.
19915 * lisp.h: Prefer 64-bit EMACS_INT if available.
19916 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19917 on 32-bit hosts that have 64-bit int, so that they can access
19919 However, temporarily disable this change unless the temporary
19920 symbol WIDE_EMACS_INT is defined.
19922 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19924 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19925 This removes an assumption that EMACS_INT and long are the same
19926 width as pointers. The assumption is true for Emacs porting targets
19927 now, but we want to make other targets possible.
19928 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19929 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19930 In the rest of the code, change types of integers that hold casted
19931 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19932 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19933 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19934 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19935 No need to cast type when ORing.
19936 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19937 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19938 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19939 assume EMACS_INT is the same width as char *.
19940 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19941 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19942 Remove no-longer-needed casts.
19943 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19944 (xg_tool_bar_help_callback, xg_make_tool_item):
19945 Use EMACS_INTPTR to hold an integer
19946 that will be cast to void *; this can avoid a GCC warning
19947 if EMACS_INT is not the same width as void *.
19948 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19949 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19950 (current_message_1, set_message_1):
19951 Use a local to convert to proper width without a cast.
19952 * xmenu.c (dialog_selection_callback): Likewise.
19954 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19955 Also, don't assume VALBITS / RAND_BITS is less than 5,
19956 and don't rely on undefined behavior when shifting a 1 left into
19958 * lisp.h (get_random): Change signature to match.
19960 * lread.c (hash_string): Use size_t, not int, for hash computation.
19961 Normally we prefer signed values; but hashing is special, because
19962 it's better to use unsigned division on hash table sizes so that
19963 the remainder is nonnegative. Also, size_t is the natural width
19964 for hashing into memory. The previous code used 'int', which doesn't
19965 retain enough info to hash well into very large tables.
19966 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19968 * dbusbind.c: Don't possibly lose pointer info when converting.
19969 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19970 Use XPNTR rather than XHASH, so that the high-order bits of
19971 the pointer aren't lost when converting through void *.

20058 * process.c: Include lisp.h before w32.h, not after.
20059 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20060 instead of gnutls_record_check_pending.
20062 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20064 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20066 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

20112 rather than `XVECTOR (FOO)->size'.
20114 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20115 inttypes.h, as a gnulib replacement is used if it not available in
20118 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20120 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

20137 %llo or %llx format is passed. (Bug#8545)
20139 * window.c (window_scroll_line_based): Use a marker instead of
20140 simple variables to record original value of point. (Bug#7952)
20142 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20143 produced by %s or %c overflows available buffer space. (Bug#8545)
20145 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20147 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20148 (SIZE_MAX): Move defn after all includes, as they might #define it.
20150 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20152 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20154 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20156 * keyboard.c (Qdelayed_warnings_hook): Define.
20157 (command_loop_1): Run `delayed-warnings-hook'
20158 if Vdelayed_warnings_list is non-nil.
20159 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20160 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20162 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20164 * doprnt.c (doprnt): Don't return value smaller than the buffer
20165 size if the message was truncated. (Bug#8545).
20167 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20169 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20170 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20172 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20174 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20176 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20178 * makefile.w32-in: Update dependencies.
20180 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20182 Improve `doprnt' and its usage. (Bug#8545)
20183 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20184 `format_end'. Remove support for %l as a conversion specifier.
20185 Don't use xrealloc. Improve diagnostics when the %l size modifier
20186 is used. Update the commentary.
20188 * eval.c (verror): Simplify calculation of size_t.
20190 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20193 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20195 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20198 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20200 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20201 This makes this file independent of the recent pseudovector change.
20203 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20205 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20207 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20208 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20209 Remove unused local.
20210 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20212 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20213 GCC 4.6.0 optimizes based on type-based alias analysis.
20214 For example, if b is of type struct buffer * and v of type struct
20215 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20216 != &v->size, and therefore "v->size = 1; b->size = 2; return
20217 v->size;" must therefore return 1. This assumption is incorrect
20218 for Emacs, since it type-puns struct Lisp_Vector * with many other
20219 types. To fix this problem, this patch adds a new type struct
20220 vectorlike_header that documents the constraints on layout of vectors
20221 and pseudovectors, and helps optimizing compilers not get fooled
20222 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20223 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20224 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20226 (XSETPVECTYPE): Rewrite in terms of new macro.
20227 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20228 This is a bit clearer, and further avoids the possibility of
20229 undesirable aliasing.
20230 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20231 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20232 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20233 since Lisp_Subr is a special case (no "next" field).
20234 (ASIZE): Now uses header.size rather than size.
20235 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20236 to avoid the hassle of writing XVECTOR (foo)->header.size.
20237 (struct vectorlike_header): New type.
20238 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20239 object, to help avoid aliasing.
20240 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20241 (SUBRP): Likewise, since Lisp_Subr is a special case.
20242 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20243 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20244 (struct Lisp_Hash_Table): Combine first two members into a single
20245 struct vectorlike_header member. All uses of "size" and "next" members
20246 changed to be "header.size" and "header.next".
20247 * buffer.h (struct buffer): Likewise.
20248 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20249 * frame.h (struct frame): Likewise.
20250 * process.h (struct Lisp_Process): Likewise.
20251 * termhooks.h (struct terminal): Likewise.
20252 * window.c (struct save_window_data, struct saved_window): Likewise.
20253 * window.h (struct window): Likewise.
20254 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20255 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20256 * buffer.c (init_buffer_once): Likewise.
20257 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20259 * process.c (Fformat_network_address): Use local var for size,
20262 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20264 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20265 * data.c (atof): Remove decl; no longer used or needed.
20266 (digit_to_number): Move to lread.c.
20267 (Fstring_to_number): Use new string_to_number function, to be
20268 consistent with how the Lisp reader treats infinities and NaNs.
20269 Do not assume that floating-point numbers represent EMACS_INT
20270 without losing information; this is not true on most 64-bit hosts.
20271 Avoid double-rounding errors, by insisting on integers when
20272 parsing non-base-10 numbers, as the documentation specifies.
20273 * lisp.h (string_to_number): New decl, replacing ...
20274 (isfloat_string): Remove.
20275 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20276 (read1): Do not accept +. and -. as integers; this
20277 appears to have been a coding error. Similarly, do not accept
20278 strings like +-1e0 as floating point numbers. Do not report
20279 overflow for integer overflows unless the base is not 10 which
20280 means we have no simple and reliable way to continue.
20281 Break out the floating-point parsing into a new
20282 function string_to_number, so that Fstring_to_number parses
20283 floating point numbers consistently with the Lisp reader.
20284 (digit_to_number): Move here from data.c. Make it static inline.
20285 (E_CHAR, EXP_INT): Remove, replacing with ...
20286 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20287 (string_to_number): New function, replacing isfloat_string.
20288 This function checks for valid syntax and produces the resulting
20289 Lisp float number too. Rework it so that string-to-number
20290 no longer mishandles examples like "1.0e+". Use strtoumax,
20291 so that overflow for non-base-10 numbers is reported only when
20292 there's no portable and simple way to convert to floating point.
20294 * textprop.c (set_text_properties_1): Rewrite for clarity,
20295 and to avoid GCC warning about integer overflow.
20297 * intervals.h (struct interval): Use EMACS_INT for members
20298 where EMACS_UINT might cause problems. See
20299 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20300 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20301 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20303 (offset_intervals): Tell GCC not to worry about length overflow
20304 when negating a negative length.
20306 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20307 (overrun_check_free): Likewise.
20309 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20310 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20313 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20314 (gnutls_make_error): Rename local to avoid shadowing.
20315 (gnutls_emacs_global_deinit): ifdef out; not used.
20316 (Fgnutls_boot): Use const for pointer to readonly storage.
20317 Comment out unused local. Fix pointer signedness problems.
20319 * lread.c (openp): Don't stuff size_t into an 'int'.
20320 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20321 about possible signed overflow.
20323 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20324 (GDK_KEY_g): Don't define if already defined.
20325 (xg_prepare_tooltip): Avoid pointer signedness problem.
20326 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20328 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20329 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20331 * xfns.c (Fx_window_property): Simplify a bit,
20332 to make a bit faster and to avoid GCC 4.6.0 warning.
20333 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20335 * fns.c (internal_equal): Don't assume size_t fits in int.
20337 * alloc.c (compact_small_strings): Tighten assertion a little.
20339 Replace pEd with more-general pI, and fix some printf arg casts.
20340 * lisp.h (pI): New macro, generalizing old pEd macro to other
20341 conversion specifiers. For example, use "...%"pI"d..." rather
20342 than "...%"pEd"...".
20343 (pEd): Remove. All uses replaced with similar uses of pI.
20344 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20345 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20346 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20347 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20348 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20349 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20350 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20352 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20353 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20354 * print.c (safe_debug_print, print_object): Likewise.
20355 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20357 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20358 avoiding the 0 flag, which is not portable.
20359 * process.c (Fmake_network_process): Use pI to avoid cast.
20360 * region-cache.c (pp_cache): Likewise.
20361 * xdisp.c (decode_mode_spec): Likewise.
20362 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20363 behavior on 64-bit hosts with printf arg.
20364 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20365 (x_stop_queuing_selection_requests): Likewise.
20366 (x_get_window_property): Don't truncate byte count to an 'int'
20369 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20370 here, since it parses constructs like leading '-' and spaces,
20371 which are not wanted; and it overflows with large numbers.
20372 Instead, simply match F[0-9]+, which is what is wanted anyway.
20374 * alloc.c: Remove unportable assumptions about struct layout.
20375 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20376 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20377 (allocate_vectorlike, make_pure_vector): Use the new macros,
20378 plus offsetof, to remove unportable assumptions about struct layout.
20379 These assumptions hold on all porting targets that I know of, but
20380 they are not guaranteed, they're easy to remove, and removing them
20381 makes further changes easier.
20383 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20384 This doesn't fix a bug but makes the code clearer.
20385 (string_overrun_cookie): Now const. Use initializers that
20386 don't formally overflow signed char, to avoid warnings.
20387 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20388 can cause Emacs to crash when string overrun checking is enabled.
20389 (allocate_buffer): Don't assume sizeof (struct buffer) is a

21284 * syntax.c (skip_chars): Likewise.
21286 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21287 This also lets GCC 4.6.0 generate slightly better loop code.
21289 * callint.c (Fcall_interactively): <, not <=, for optimization.
21290 (Fcall_interactively): Count the number of arguments produced,
21291 not the number of arguments given. This is simpler and lets GCC
21292 4.6.0 generate slightly better code.
21294 * ftfont.c: Distingish more carefully between FcChar8 and char.
21295 The previous code passed unsigned char * to a functions like
21296 strlen and xstrcasecmp that expect char *, which does not
21297 conform to the C standard.
21298 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21299 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21300 char * when the C standard requires it.
21302 * keyboard.c (read_char): Remove unused var.
21304 * eval.c: Port to Windows vsnprintf (Bug#8435).
21305 Include <limits.h>.
21306 (SIZE_MAX): Define if the headers do not.
21307 (verror): Do not give up if vsnprintf returns a negative count.
21308 Instead, grow the buffer. This ports to Windows vsnprintf, which
21309 does not conform to C99. Problem reported by Eli Zaretskii.
21310 Also, simplify the allocation scheme, by avoiding the need for
21311 calling realloc, and removing the ALLOCATED variable.
21313 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21315 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21316 But keep the doprint source code for now, as we might revamp it
21317 and use it again (Bug#8435).
21318 * lisp.h (doprnt): Remove.
21319 * Makefile.in (base_obj): Remove doprnt.o.
21320 * deps.mk (doprnt.o): Remove.
21322 error: Print 32- and 64-bit integers portably (Bug#8435).
21323 Without this change, on typical 64-bit hosts error ("...%d...", N)
21324 was used to print both 32- and 64-bit integers N, which relied on
21325 undefined behavior.
21326 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21327 * lisp.h (error, verror): Mark as printf-like functions.
21328 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21329 Report overflow in size calculations when allocating printf buffer.
21330 Do not truncate output string at its first null byte.
21331 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21332 Truncate the output at a character boundary, since vsnprintf does not
21334 * charset.c (check_iso_charset_parameter): Convert internal
21335 character to string before calling 'error', since %c now has the
21337 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21338 overflow when computing char to be passed to 'error'. Do not
21339 pass Lisp_Object to 'error'; pass the integer instead.
21340 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21341 formatted with plain %d.
21343 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21345 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21347 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21349 * xterm.c (x_catch_errors): Remove duplicate declaration.
21351 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21353 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21355 2011-04-10 Jim Meyering <meyering@redhat.com>
21357 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21358 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21359 return ssize_t not "int", and use size_t as the buffer length.
21360 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21361 * gnutls.h: Update declarations.
21362 * process.c (read_process_output): Use ssize_t, to match.
21363 (send_process): Likewise.
21365 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21367 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21369 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21371 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21372 Use unsigned char, to match FcChar8 type definition.
21374 * xterm.c (handle_one_xevent):
21375 * xmenu.c (create_and_show_popup_menu):
21376 * xselect.c (x_decline_selection_request)
21377 (x_reply_selection_request): Avoid type-punned deref of X events.
21379 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21381 Fix some uses of `int' instead of EMACS_INT.
21382 * search.c (string_match_1, fast_string_match)
21383 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21384 (scan_buffer, find_next_newline_no_quit)
21385 (find_before_next_newline, search_command, Freplace_match)
21386 (Fmatch_data): Make some `int' variables be EMACS_INT.
21388 * xdisp.c (display_count_lines): 3rd argument and return value now
21389 EMACS_INT. All callers changed.
21390 (pint2hrstr): Last argument is now EMACS_INT.
21392 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21393 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21394 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
21395 (decode_coding_utf_16, decode_coding_emacs_mule)
21396 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
21397 (decode_coding_ccl, decode_coding_charset)
21398 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
21399 (decode_coding_iso_2022, decode_coding_emacs_mule)
21400 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
21401 <char_offset, last_offset>: Declare EMACS_INT.
21402 (encode_coding_utf_8, encode_coding_utf_16)
21403 (encode_coding_emacs_mule, encode_invocation_designation)
21404 (encode_designation_at_bol, encode_coding_iso_2022)
21405 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21406 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21408 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21409 (encode_invocation_designation): Last argument P_NCHARS is now
21411 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21412 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21414 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21417 * ccl.c (Fccl_execute_on_string): Declare some variables
21420 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21422 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21424 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21426 * process.c (Fformat_network_address): Doc fix.
21428 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21430 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21432 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21434 * keyboard.c (read_char): Call Lisp function help-form-show,
21435 instead of using internal_with_output_to_temp_buffer.
21436 (Qhelp_form_show): New var.
21437 (syms_of_keyboard): Use DEFSYM macro.
21439 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21441 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21443 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21445 * process.c (Flist_processes): Remove to Lisp.
21446 (list_processes_1): Delete.
21448 2011-04-06 Eli Zaretskii <eliz@gnu.org>
21450 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21452 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21454 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21456 Fix more problems found by GCC 4.6.0's static checks.
21458 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
21460 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21462 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21464 * xdisp.c (vmessage): Mark as a printf-like function.
21466 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21468 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21470 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21471 printf-like functions.
21472 (tiff_load): Add casts to remove these marks before passing them
21473 to system-supplied API.
21475 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21477 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21478 This avoids several warnings with gcc -Wstrict-overflow.
21479 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21480 directly, rather than having caller test rule sign. This avoids
21481 some unnecessary tests.
21482 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21483 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21484 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21486 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21487 (xfont_open): Avoid unnecessary tests.
21489 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21491 * composite.h, composite.c (composition_gstring_put_cache):
21492 Use EMACS_INT, not int, for length.
21494 * composite.h (COMPOSITION_DECODE_REFS): New macro,
21495 breaking out part of COMPOSITION_DECODE_RULE.
21496 (COMPOSITION_DECODE_RULE): Use it.
21497 * composite.c (get_composition_id): Remove unused local vars,
21498 by using the new macro.
21500 * textprop.c (set_text_properties_1): Change while to do-while,
21501 since the condition is always true at first.
21503 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21504 (interval_deletion_adjustment): Return unsigned value.
21507 * process.c (list_processes_1, create_pty, read_process_output):
21508 (exec_sentinel): Remove vars that were set but not used.
21509 (create_pty): Remove unnecessary "volatile"s.

21512 (read_process_output): Simplify nbytes computation if buffered.
21514 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
21516 * syntax.c (scan_words): Remove var that was set but not used.
21517 (update_syntax_table): Use unsigned instead of int.
21519 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21520 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21521 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21523 * print.c (print_error_message): Avoid int overflow.
21525 * font.c (font_list_entities): Redo for clarity,
21526 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21528 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21529 (font_score): Avoid potential overflow in diff calculation.
21531 * fns.c (substring_both): Remove var that is set but not used.
21532 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21534 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21536 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21537 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21538 can always succeed if overflow has undefined behavior.
21540 * search.c (boyer_moore, wordify): Remove vars set but not used.
21541 (wordify): Omit three unnecessary tests.
21543 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21544 All callers changed. This avoids the need for an unused var.
21546 * casefiddle.c (casify_region): Remove var that is set but not used.
21548 * dired.c (file_name_completion): Remove var that is set but not used.
21550 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21552 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21553 (Finsert_file_contents): Remove unnecessary code checking fd.
21555 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21556 Check for integer overflow on size calculations.
21558 * buffer.c (Fprevious_overlay_change): Remove var that is set
21561 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21562 Remove vars that are set but not used.
21563 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21564 (timer_check_2): Mark vars as initialized.
21566 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21568 * image.c (lookup_image): Remove var that is set but not used.
21569 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21571 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21572 that are set but not used.
21574 * xfns.c (make_invisible_cursor): Don't return garbage
21575 if XCreateBitmapFromData fails (Bug#8410).
21577 * xselect.c (x_get_local_selection, x_handle_property_notify):
21578 Remove vars that are set but not used.
21580 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21581 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21583 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21584 Remove var that is set but not used.
21585 (scroll_bar_windows_size): Now size_t, not int.
21586 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21587 Check for overflow.
21589 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21590 (map_tty_color) [!defined MSDOS]: Likewise.
21592 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21594 * coding.c: Remove vars that are set but not used.
21595 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21596 All callers changed.
21597 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21598 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21599 (decode_coding_charset): Remove vars that are set but not used.
21601 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21602 that is set but not used.
21604 * print.c (print_object): Remove var that is set but not used.
21606 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21607 The gnulib version avoids calling malloc in the usual case,
21608 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21609 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21610 * filelock.c (current_lock_owner): Likewise.
21611 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21612 * sysdep.c: Include allocator.h, careadlinkat.h.
21613 (emacs_no_realloc_allocator): New static constant.
21614 (emacs_readlink): New function.
21615 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21616 ../lib/careadlinkat.h.
21618 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21620 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21621 first non-nil return value).
21623 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21625 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21626 if not defined (Bug#8403).
21628 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21630 * xdisp.c (display_count_lines): Remove parameter `start',
21631 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21632 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21633 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21634 (fill_stretch_glyph_string): Remove parameters `row' and `area',
21635 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21636 and thereabouts. All callers changed.
21637 (get_per_char_metric): Remove parameter `f', unused since
21638 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21640 2011-04-02 Jim Meyering <meyering@redhat.com>
21642 do not dereference NULL upon failed strdup
21643 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21644 (ns_get_family): Likewise.
21646 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21648 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21650 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21652 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21655 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21657 Add lexical binding.
21659 * window.c (Ftemp_output_buffer_show): New fun.
21660 (Fsave_window_excursion):
21661 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21663 * lread.c (lisp_file_lexically_bound_p): New function.
21664 (Fload): Bind Qlexical_binding.
21665 (readevalloop): Remove `evalfun' arg.
21666 Bind Qinternal_interpreter_environment.
21667 (Feval_buffer): Bind Qlexical_binding.
21668 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21670 (syms_of_lread): Declare `lexical-binding'.
21672 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21674 * keyboard.c (eval_dyn): New fun.
21675 (menu_item_eval_property): Use it.
21677 * image.c (parse_image_spec): Use Ffunctionp.
21679 * fns.c (concat, mapcar1): Accept byte-code-functions.
21681 * eval.c (Fsetq): Handle lexical vars.
21682 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21683 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21684 (FletX, Flet): Obey lexical binding.
21685 (Fcommandp): Handle closures.
21686 (Feval): New `lexical' arg.
21687 (eval_sub): New function extracted from Feval. Use it almost
21688 everywhere where Feval was used. Look up vars in lexical env.
21690 (Ffunctionp): Move from subr.el.
21691 (Ffuncall): Handle closures.
21692 (apply_lambda): Remove `eval_flags'.
21693 (funcall_lambda): Handle closures and new byte-code-functions.
21694 (Fspecial_variable_p): New function.
21695 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21696 but without exporting it to Lisp.
21698 * doc.c (Fdocumentation, store_function_docstring):
21699 * data.c (Finteractive_form): Handle closures.
21701 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21704 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21706 (exec_byte_code): New function extracted from Fbyte_code to handle new
21707 calling convention for byte-code-functions. Add new byte-codes.
21709 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21711 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21713 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21715 * xdisp.c (redisplay_internal): Fix prototype.
21717 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21719 * xdisp.c (SCROLL_LIMIT): New macro.
21720 (try_scrolling): Use it when setting scroll_limit.
21721 Limit scrolling to 100 screen lines.
21722 (redisplay_window): Even when falling back on "recentering",
21723 position point in the window according to scroll-conservatively,
21724 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21726 (try_scrolling): When point is above the window, allow searching
21727 as far as scroll_max, or one screenful, to compute vertical
21728 distance from PT to the scroll margin position. This prevents
21729 try_scrolling from unnecessarily failing when
21730 scroll-conservatively is set to a value slightly larger than the
21731 window height. Clean up the case of PT below the margin at bottom
21732 of window: scroll_max can no longer be INT_MAX. When aggressive
21733 scrolling is in use, don't let point enter the opposite scroll
21734 margin as result of the scroll.
21735 (syms_of_xdisp) <scroll-conservatively>: Document the
21736 threshold of 100 lines for never-recentering scrolling.
21738 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21740 * dispextern.h (move_it_by_lines):
21741 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21742 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21743 (message_log_check_duplicate): Remove parameters `prev_bol' and
21744 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21745 (redisplay_internal): Remove parameter `preserve_echo_area',
21746 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21748 * indent.c (Fvertical_motion):
21749 * window.c (window_scroll_pixel_based, Frecenter):
21750 Don't pass `need_y_p' to `move_it_by_lines'.
21752 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21754 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21755 steal a few bits to be more compact.
21756 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21757 Remove unneeded casts.
21759 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21761 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21763 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21764 binding" message (bug#7967).
21766 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21768 Fix more problems found by GCC 4.6.0's static checks.
21770 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21771 Remove unused local var.
21773 * editfns.c (Fmessage_box): Remove unused local var.
21775 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21776 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21777 Omit unused local vars.
21778 * window.c (shrink_windows): Omit unused local var.
21779 * menu.c (digest_single_submenu): Omit unused local var.
21780 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21781 Omit unused local var.
21783 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21784 Don't assume string length fits in int.
21785 (keyremap_step, read_key_sequence): Use size_t for sizes.
21786 (read_key_sequence): Don't check last_real_key_start redundantly.
21788 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21789 instead of alloca (Bug#8344).
21791 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21792 (Fbacktrace_frame): Don't assume nframes fits in int.
21794 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21796 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21799 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21801 * cm.c (calccost): Turn while-do into do-while, for clarity.
21803 * keyboard.c (syms_of_keyboard): Use the same style as later
21804 in this function when indexing through an array. This also
21805 works around GCC bug 48267.
21807 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21809 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

21812 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21814 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21815 This avoids undefined behavior on integer overflow, and is a bit
21816 more convenient anyway since it is compared to a size_t variable.
21818 Variadic C functions now count arguments with size_t, not int.
21819 This avoids an unnecessary limitation on 64-bit machines, which
21820 caused (substring ...) to crash on large vectors (Bug#8344).
21821 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21822 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
21823 All variadic functions and their callers changed accordingly.
21824 (struct gcpro.nvars): Now size_t, not int. All uses changed.

21828 (internal_condition_case_n, run_hook_with_args, apply_lambda)
21829 (funcall_lambda, mark_backtrace): Likewise.
21830 * fns.c (concat): Likewise.
21831 * frame.c (x_set_frame_parameters): Likewise.
21832 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21833 0 if not found, not -1. All callers changed.
21835 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21836 (stack_copy_size): Now size_t, not int.
21837 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

21842 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21843 All callers changed.
21845 * lisp.h (multibyte_char_to_unibyte):
21846 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21847 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
21848 * character.h (CHAR_TO_BYTE8):
21849 * cmds.c (internal_self_insert):
21850 * editfns.c (general_insert_function):
21851 * keymap.c (push_key_description):
21852 * search.c (Freplace_match):
21853 * xdisp.c (message_dolog, set_message_1): All callers changed.
21855 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
21857 * keyboard.c (safe_run_hook_funcall): New function.
21858 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21859 don't set the hook to nil, but remove the offending function instead.
21860 (Qcommand_hook_internal): Remove, unused.
21861 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21862 Vcommand_hook_internal.
21864 * eval.c (enum run_hooks_condition): Remove.
21865 (funcall_nil, funcall_not): New functions.
21866 (run_hook_with_args): Call each function through a `funcall' argument.
21867 Remove `cond' argument, now redundant.
21868 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21869 (Frun_hook_with_args_until_failure): Adjust accordingly.
21870 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
21872 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21874 * dispextern.h (string_buffer_position): Remove declaration.
21876 * print.c (strout): Remove parameter `multibyte', unused since
21877 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21879 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21880 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21881 All callers changed.
21883 * w32.c (_wsa_errlist): Use braces for struct initializers.
21885 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
21886 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
21887 All callers changed.
21888 (string_buffer_position): Likewise. Also, make static (it's never
21889 used outside xdisp.c).

21893 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21894 All callers changed.
21896 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21898 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21909 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
21911 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

21924 2011-03-26 Eli Zaretskii <eliz@gnu.org>
21926 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
21927 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
21929 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
21931 * w32.c (read_unc_volume): Use parameter `henum', instead of
21932 global variable `wget_enum_handle'.
21934 * keymap.c (describe_vector): Remove parameters `indices' and
21935 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

21950 * gtkutil.c (xg_maybe_add_timer):
21951 * keyboard.c (readable_events):
21952 * process.c (wait_reading_process_output):
21953 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
21955 * insdel.c (adjust_markers_gap_motion):
21956 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

22030 2011-03-23 Julien Danjou <julien@danjou.info>
22032 * term.c (Fsuspend_tty, Fresume_tty):
22033 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22034 * window.c (temp_output_buffer_show):
22035 * insdel.c (signal_before_change):
22036 * frame.c (Fhandle_switch_frame):

22039 * editfns.c (save_excursion_restore):
22040 * cmds.c (internal_self_insert):
22041 * callint.c (Fcall_interactively):
22042 * buffer.c (Fkill_all_local_variables):
22043 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22045 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22046 unconditionally since it does the check itself.
22048 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22050 Fix more problems found by GCC 4.5.2's static checks.
22052 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22053 the first time through the loop, since we know p0 < p1 then.
22054 This also avoids a gcc -Wstrict-overflow warning.
22056 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22057 leading to a memory leak, possible in functions like
22058 load_charset_map_from_file that can allocate an unbounded number
22059 of objects (Bug#8318).
22061 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22062 that could (at least in theory) be that large.
22064 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22065 This is less likely to overflow, and avoids undefined behavior if
22066 overflow does occur. All callers changed. Use strtoul to scan
22067 for the unsigned long integer.
22068 (pint2hrstr): Simplify and tune code slightly.
22069 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

22077 This also avoids a warning with gcc -Wstrict-overflow.
22079 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22082 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22084 * process.c (Fmake_network_process): Use socklen_t, not int,
22085 where POSIX says socklen_t is required in portable programs.
22086 This fixes a porting bug on hosts like 64-bit HP-UX, where
22087 socklen_t is wider than int (Bug#8277).
22088 (Fmake_network_process, server_accept_connection):
22089 (wait_reading_process_output, read_process_output):
22092 * process.c: Rename or move locals to avoid shadowing.
22093 (list_processes_1, Fmake_network_process):
22094 (read_process_output_error_handler, exec_sentinel_error_handler):
22095 Rename or move locals.
22096 (Fmake_network_process): Define label "retry_connect" only if needed.
22097 (Fnetwork_interface_info): Fix pointer signedness.
22098 (process_send_signal): Add cast to avoid pointer signedness problem.
22099 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22100 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22102 Make tparam.h and terminfo.c consistent.
22103 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22104 Include tparam.h instead, since it declares them.
22105 * cm.h (PC): Remove extern decl; tparam.h now does this.
22106 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22107 * terminfo.c: Include tparam.h, to check interfaces.
22108 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22109 (tparam): Adjust signature to match interface in tparam.h;
22110 this removes some undefined behavior. Check that outstring and len
22111 are zero, which they always are with Emacs.
22112 * tparam.h (PC, BC, UP): New extern decls.
22114 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22115 (xftfont_open): Rename locals to avoid shadowing.
22117 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
22118 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
22119 (OTF_TAG_SYM): Omit macro if not needed.
22120 (ftfont_list): Remove unused local.
22121 (get_adstyle_property, ftfont_pattern_entity):
22122 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
22123 Rename locals to avoid shadowing.
22125 * xfont.c (xfont_list_family): Mark var as initialized.
22127 * xml.c (make_dom): Now static.
22129 * composite.c (composition_compute_stop_pos): Rename local to
22131 (composition_reseat_it): Remove unused locals.
22132 (find_automatic_composition, composition_adjust_point): Likewise.
22133 (composition_update_it): Mark var as initialized.
22134 (find_automatic_composition): Mark vars as initialized,
22135 with a FIXME (Bug#8290).
22137 character.h: Rename locals to avoid shadowing.
22138 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22139 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22140 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22141 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22142 to avoid shadowing.
22144 * textprop.c (property_change_between_p): Remove; unused.
22146 * intervals.c (interval_start_pos): Now static.
22148 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
22150 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
22151 Rename locals to avoid shadowing.
22153 * sound.c (wav_play, au_play, Fplay_sound_internal):
22154 Fix pointer signedness.
22155 (alsa_choose_format): Remove unused local var.
22156 (wav_play): Initialize a variable to 0, to prevent undefined
22157 behavior (Bug#8278).
22159 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22161 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22163 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22164 clobbering (Bug#8298).
22165 * sysdep.c (sys_subshell): Likewise.
22166 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22168 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22169 This should get cleaned up, so that child_setup has the
22170 same signature on all platforms.
22172 * callproc.c (call_process_cleanup): Now static.
22173 (relocate_fd): Rename locals to avoid shadowing.
22175 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

22342 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22343 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22344 to use the following functions instead of these macros.
22345 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22346 EMACS_INT, since callers assume the returned value fits in int.
22347 (upcase1): Likewise, for UPCASE_TABLE.
22348 (uppercasep, lowercasep, upcase): New static inline functions.
22349 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22359 (regex_compile, re_match_2_internal): Mark locals as initialized.
22360 (RETALLOC_IF): Define only if needed.
22361 (WORDCHAR_P): Likewise. This one is never needed, but is used
22362 only in a comment talking about a compiler bug, so put inside
22363 the #if 0 of that comment.
22364 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22365 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

22391 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22392 New macros, so that the caller can use some names other than
22393 gcpro1, gcpro2, etc.
22394 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22396 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22397 argument, for consistency with GCPRO2_VAR, etc: it is now the
22398 prefix of the variable, not the variable itself. All uses
22400 * dired.c (directory_files_internal, file_name_completion):
22401 Rename locals to avoid shadowing.
22403 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22404 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22405 dired.c's scmp function, had undefined behavior.
22406 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22407 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22408 * buffer.h: ... to here, because these macros use current_buffer,
22409 and the new implementation with inline functions needs to have
22410 current_buffer in scope now, rather than later when the macros
22412 (downcase, upcase1): New static inline functions.
22413 (DOWNCASE, UPCASE1): Reimplement using these functions.
22414 This avoids undefined behavior in expressions like
22415 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22416 from race conditions in accessing the global variables
22417 case_temp1 and case_temp2.
22418 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22419 * lisp.h (case_temp1, case_temp2): Remove their decls.
22420 * character.h (ASCII_CHAR_P): Move from here ...
22421 * lisp.h: ... to here, so that the inline functions mentioned
22422 above can use them.
22424 * dired.c (directory_files_internal_unwind): Now static.
22426 * fileio.c (file_name_as_directory, directory_file_name):

22429 (file_name_as_directory): Use const pointers when appropriate.
22430 (Fexpand_file_name): Likewise. In particular, newdir might
22431 point at constant storage, so make it a const pointer.
22432 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22433 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22435 (Fset_file_times, Finsert_file_contents, auto_save_error):

22440 to avoid shadowing.
22442 * marker.c (bytepos_to_charpos): Remove; unused.
22444 * lisp.h (verify_bytepos, count_markers): New decls,
22445 so that gcc does not warn that these functions aren't declared.
22447 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22448 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22449 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22450 (copy_text): Remove unused local var.
22452 * filelock.c (within_one_second): Now static.
22453 (lock_file_1): Rename local to avoid shadowing.
22455 * buffer.c (fix_overlays_before): Mark locals as initialized.
22456 (fix_start_end_in_overlays): Likewise. This function should be
22457 simplified by using pointers-to-pointers, but that's a different
22459 (switch_to_buffer_1): Now static.
22460 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22461 (report_overlay_modification): Rename locals to avoid shadowing.
22463 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22464 Fix pointer signedness issue.
22465 (sys_subshell): Mark local as volatile if checking for lint,
22466 to suppress a gcc -Wclobbered warning that does not seem to be right.
22467 (MAXPATHLEN): Define only if needed.
22469 * process.c (serial_open, serial_configure): Move decls from here ...
22470 * systty.h: ... to here, so that they can be checked.
22472 * fns.c (get_random, seed_random): Move extern decls from here ...
22473 * lisp.h: ... to here, so that they can be checked.
22475 * sysdep.c (reset_io): Now static.
22476 (wait_for_termination_signal): Remove; unused.
22478 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

22481 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22482 (DENSE_TABLE_SIZE): Remove; unused.
22483 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22484 (describe_map_tree):
22485 Rename locals to avoid shadowing.
22487 * keyboard.c: Declare functions static if they are not used elsewhere.
