154 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
155 too so that these builds can use Cygwin's file conversion
156 functions. (We've been building and linking cygw32.o all along
157 and just not using it.)
159 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
161 File synchronization fixes (Bug#13944).

200 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
201 Include <sys/param.h> unconditionally, as that works elsewhere and
202 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
203 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin

289 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
290 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come

293 * keyboard.c (access_keymap_keyremap): Accept nil return value from
294 functions to mean "no change".

302 (compile_pattern, string_match_1, search_command)
303 (trivial_regexp_p, search_buffer, Freplace_match, match_limit)
304 (search_regs_saved, Fregexp_quote):
305 Use bool for boolean.
306 * region-cache.c (region_cache_forward, region_cache_backward):

309 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
311 * search.c (find_newline): Accept start and end byte positions

427 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
429 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
430 * sysdep.c (list_system_processes)
431 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
432 Make it a stub in this case; otherwise the build might fail,
433 and this code hasn't been tested on such hosts anyway.
434 Problem reported by Nelson H. F. Beebe in
435 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
436 and analyzed by Jérémie Courrèges-Anglas in
437 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
439 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
441 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
442 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
443 (get_visually_first_element, move_it_vertically_backward): Ajust users.
444 * bidi.c (bidi_find_paragraph_start): Likewise.
445 * indent.c (vmotion): Likewise.
447 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
449 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
450 * filelock.c: Include <c-ctype.h>.
451 (MAX_LFINFO): New top-level constant.
452 (lock_info_type): Remove members pid, boot_time. Add members at,
453 dot, colon. Change user member to be the entire buffer, not a
454 pointer. This allows us to handle the case where a foreign
455 pid or boot time exceeds the local range. All uses changed.
456 (LINKS_MIGHT_NOT_WORK): New constant.
457 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
458 (defined_WINDOWSNT): Remove.
459 (MAKE_LOCK_NAME, file_in_lock_file_name):
460 Always use .#FILE (not .#-FILE) for the file lock,
461 even if it is a regular file.
462 (rename_lock_file): New function.
463 (create_lock_file): Use it.
464 (create_lock_file, read_lock_data):
465 Prefer a symbolic link for the lock file, falling back on a
466 regular file if symlinks don't work. Do not try to create
467 symlinks on MS-Windows, due to security hassles. Stick with
468 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
469 link, rename, unlink, mkstemp) when creating locks, as a GNUish
470 host may be using a Windowsish file system, and cannot use
471 MS-Windows-only system calls. Fall back on mktemp if mkstemp
472 doesn't work. Don't fail merely because of a symlink-contents
473 length limit in the current file system; fall back on regular
474 files. Increase the symlink contents length limit to 8 KiB, this
475 should be big enough for any real use and doesn't crunch the
477 (create_lock_file, lock_file_1, read_lock_data):
478 Simplify allocation of lock file buffers now that they fit in 8 KiB.
479 (lock_file_1): Return error number, not bool. All callers changed.
480 (ELOOP): New macro, if not already defined.
481 (read_lock_data): Return size of lock file contents, not Lisp object.
482 All callers changed. Handle a race condition if some other process
483 replaces a regular-file lock with a symlink lock or vice versa,
484 while we're trying to read the lock.
485 (current_lock_owner): Parse contents more carefully, to help avoid
486 confusing a regular-file lock with some other application's use
487 of the file. Check for lock file contents being too long, or
488 not parsing correctly.
489 (current_lock_owner, lock_file):
490 Allow foreign pid and boot times that exceed the local range.
491 (current_lock_owner, lock_if_free, lock_file):
492 Simplify allocation of lock file contents.
493 * w32.c (sys_rename_replace): New function, containing most of
494 the contents of the old sys_rename.
495 (sys_rename): Use it.
496 (fchmod): New dummy function.
497 * w32.h (sys_rename_replace, fchmod): New decls.
499 2013-03-05 Eli Zaretskii <eliz@gnu.org>
501 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
502 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
503 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
504 <dmantipov@yandex.ru>.
506 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
508 * composite.c (get_composition_id, fill_gstring_header):
509 Use make_uninit_vector where appropriate.
510 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
511 * xselect.c (clean_local_selection_data): Likewise.
513 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
515 Fix misuse of ImageMagick that caused core dump (Bug#13846).
516 * image.c (imagemagick_load_image): Calculate height and width
517 after flattening the image, not before.
519 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
521 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
522 * ftfont.c (ftfont_shape_by_flt): Likewise.
523 * w32uniscribe.c (uniscribe_shape): Likewise.
525 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
527 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
528 The old approach, which fell back on DIR/.#FILE.0 through
529 DIR/.#FILE.9, had race conditions that could not be easily fixed.
530 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
531 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
532 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
533 because the locking mechanism was never reliable in that case).
534 This patch fixes this and other bugs discovered by a code
535 inspection that was prompted by
536 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
537 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
538 to avoid interoperability problems between the MS-Windows and
539 non-MS-Windows implementations. MS-Windows and non-MS-Windows
540 instances of Emacs now ignore each others' locks.
541 * filelock.c (defined_WINDOWSNT): New constant.
542 (MAKE_LOCK_NAME, fill_in_lock_file_name):
543 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
544 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
545 regular files on MS-Windows hosts.
546 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
547 Use SAFE_ALLOCA to avoid problems with long file names.
548 (MAX_LFINFO): Now a local constant, not a global macro.
549 (IS_LOCK_FILE): Remove.
550 (lock_file_1): Don't inspect errno if symlink call succeeds;
552 (lock_file): Document that this function can return if lock
554 (lock_file): Don't access freed storage.
556 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

560 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
562 * textprop.c: Use bool for booleans.
563 (validate_interval_range, Fadd_text_properties)
564 (Fremove_text_properties): Prefer bool to int when either works.
566 2013-03-02 Eli Zaretskii <eliz@gnu.org>
568 * textprop.c (Fadd_text_properties, Fremove_text_properties):
569 If the interval tree changes as a side effect of calling
570 modify_region, re-do processing starting from the call to
571 validate_interval_range. (Bug#13743)
573 2013-02-28 Eli Zaretskii <eliz@gnu.org>
575 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
578 2013-02-27 Eli Zaretskii <eliz@gnu.org>
580 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
581 _SH_DENYRW flag, instead of emacs_open, to deny any other process
582 access to the lock file until it is written and closed.
585 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
587 * callint.c (Qcall_interactively):
588 * macros.c (Qexecute_kbd_macro):

593 * window.c (Frecenter): Tiny docstring enhancement.
595 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
597 Minor textprop integer cleanup.
598 * intervals.h, textprop.c (add_text_properties_from_list):
599 Return void, not int, since nobody uses the return value.
600 * textprop.c (validate_plist, add_properties, remove_properties)
601 (Fadd_text_properties):
602 Don't assume list length fits in int.
603 (interval_has_all_properties, interval_has_some_properties)
604 (interval_has_some_properties_list, add_properties, remove_properties)
605 (Fadd_text_properties, Fremove_text_properties)
606 (Fremove_list_of_text_properties, text_property_stickiness):
607 Use bool for booleans.
608 (Fadd_text_properties, Fremove_text_properties):
609 (Fremove_list_of_text_properties):
610 Reindent do-while as per GNU style.
612 2013-02-25 Eli Zaretskii <eliz@gnu.org>
614 Implement CLASH_DETECTION for MS-Windows.
616 * filelock.c [WINDOWSNT]: Include w32.h.
617 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
618 function of that name. Up-case the macro arguments.
619 (IS_LOCK_FILE): New macro.
620 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
621 (create_lock_file): New function, with body extracted from
623 [WINDOWSNT]: Implement lock files by writing a regular file with
624 the lock information as its contents.
625 (read_lock_data): New function, on Posix platforms just calls
627 [WINDOWSNT]: Read the lock info from the file.
628 (current_lock_owner): Call read_lock_data instead of calling
629 emacs_readlinkat directly.
630 (lock_file) [WINDOWSNT]: Run the file name through
633 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
634 just check if the process by that PID exists.
636 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
637 also present, as doing so will fail to error out if the file
640 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
642 * textprop.c (Fadd_text_properties, Fremove_text_properties)
643 (Fremove_list_of_text_properties): Skip all of the intervals in
644 the region between START and END that already have resp. don't
645 have the requested properties, not just the first one.
646 Add assertions that the loop afterwards always modifies the
647 properties. (Bug#13743)
649 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
651 * callint.c (Fcall_interactively): Use the right lexical environment

659 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
660 (START_FILES): Remove. All uses removed.
661 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
662 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
663 (buildobj.h): Use it.
664 ($(ALLOBJS)): Depend on globals.h.
665 (temacs$(EXEEXT)): Use $(ALLOBJS).
666 * autodeps.mk (ALLOBJS): Move to Makefile.in.
667 * deps.mk (vm-limit.o):

671 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
672 [__GNUC__ && !ORDINARY_LINK]: Remove.

676 (make_hdr): Use DATA_START instead of start_of_data.
677 * vm-limit.c: Move most of mem-limits.h's contents here.
678 (data_start): New decl. It's OK if this is approximate,
679 so simplify-away some unnecessary exactness.
680 (POINTER): Remove; all uses removed.
681 (data_space_start): Now char *, to avoid casts.
682 (exceeds_lisp_ptr): New function, replacing the old
683 EXCEEDS_LISP_PTR macro. All uses changed.
684 (check_memory_limits): Simplify and remove casts.
685 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

690 * xdisp.c (set_message): Only check for debug-on-message if STRING
691 is a string. (Bug#13797)
693 2013-02-24 Paul Eggert <eggert@cs.ucla.edu>

696 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
697 2012-07-10 patch to this file. Reported by Eli Zaretskii in
698 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
699 and diagnosed by Andreas Schwab in
700 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.

704 Assume C89 or better.
705 * ralloc.c (SIZE, POINTER, NIL):
706 * vm-limit.c (POINTER):
707 Remove, replacing all uses with C89 equivalents. These old
708 symbols were present only for porting to pre-C89 platforms.
710 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
712 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
713 This avoids warning messages reported as part of Bug#13546.

726 (syms_of_keyboard): Adjust accordingly.
728 2013-02-19 Daniel Colascione <dancol@dancol.org>
730 * sheap.c (report_sheap_usage): Use message, not message1, so
731 that we don't try to create a buffer while we're in the middle
732 of dumping Emacs. Explain why.
734 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
736 * search.c (find_newline): Return byte position in bytepos.

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

780 * w32.c (sys_chown): Remove unused function.
782 * w32term.c <input_signal_count>: Declare 'volatile'
783 unconditionally. (Bug#9066)
785 * w32.c (set_errno): Reset h_errno and don't set it to any other
786 value. Set errno instead.
787 (check_errno): Reset h_errno.

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

831 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
833 Fix AIX port (Bug#13650).
834 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
835 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
836 was #undeffed earlier, so it cannot be used as a macro here.
837 Use the constant and not the macro.
839 2013-02-15 Eli Zaretskii <eliz@gnu.org>
841 * w32proc.c (new_child): If no vacant slots are found in
842 child_procs[], make another pass looking for slots whose process
843 has exited or died. (Bug#13546)
845 * w32.c (sys_pipe): When failing due to file descriptors above
846 MAXDESC, set errno to EMFILE.
847 (_sys_read_ahead): Update cp->status when failing to read serial
848 communications input, so that the status doesn't stay at
849 STATUS_READ_IN_PROGRESS. (Bug#13546)
851 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
853 * gtkutil.c (tb_size_cb): New function.
854 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).

858 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
861 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>

873 2013-02-13 Glenn Morris <rgm@gnu.org>
875 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
877 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
879 Improve AIX port some more (Bug#13650).
880 With this, it should be as good as it was in 23.3, though it's
881 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
882 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
883 * unexaix.c (start_of_text): Remove.
884 (_data, _text): Declare as char[], not int, as AIX manual suggests.
885 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
886 (orig_load_scnptr, orig_data_scnptr):
887 Now off_t, not long, since they are file offsets.
888 (make_hdr): Use _data, not start_of_data ().
889 This is the key part of the fix.
890 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
891 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
893 * pre-crt0.c (data_start): Initialize to 1.
894 This ports to compilers that optimize the external declaration
895 'int x = 0;' as if it were 'int x;' to shrink the executable.
897 Improve AIX port (Bug#13650).
898 This doesn't fix the bug, but it makes progress: Emacs builds now.
899 * unexaix.c: Include inttypes.h, stdarg.h.
900 (report_error, report_error_1): Mark as _Noreturn.
901 (report_error): Don't report the wrong errno.
902 (report_error_1): Now varargs. All callers changed.
903 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
904 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
905 (write_ptr): Use %p to print address rather than %lx and a cast
906 to unsigned long. Grow buffer a bit, to be safer.
908 2013-02-13 Eli Zaretskii <eliz@gnu.org>
910 * bidi.c (bidi_resolve_neutral): After finding the next
911 non-neutral character, accept NEUTRAL_ON type as well, because
912 directional control characters, such as LRE and RLE, have their
913 type converted to that by bidi_resolve_weak. This avoids aborts
914 when LRE/RLE follows a run of neutrals.
915 (bidi_move_to_visually_next): Assert that return value of
916 bidi_peek_at_next_level is non-negative. Negative values will
919 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
921 Minor getenv-related fixes.
922 * callproc.c (Fcall_process_region) [!DOS_NT]:
923 Avoid unnecessary duplicate call to getenv.
924 * callproc.c (init_callproc):
925 * dispnew.c (init_display):
926 * sysdep.c (sys_subshell):
927 Omit unnecessary cast of getenv or egetenv.
929 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
931 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
934 2013-02-12 Eli Zaretskii <eliz@gnu.org>
936 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
938 (display_line): Set w->region_showing to the value of
939 it->region_beg_charpos, not to -1. This fixes redisplay
940 optimization when cursor is moved up after M->. (Bug#13623)
942 (try_scrolling): Scroll text up more if point is too close to ZV
943 and inside the scroll margin. This makes sure point is moved
944 outside the scroll margin in these cases.
946 * window.h (struct window): region_showing can no longer be
949 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
951 Tune by using memchr and memrchr.
952 * doc.c (Fsnarf_documentation):
953 * fileio.c (Fsubstitute_in_file_name):
954 * search.c (find_newline, scan_newline):
955 * xdisp.c (pos_visible_p, display_count_lines):
956 Use memchr and memrchr rather than scanning byte-by-byte.
957 * search.c (find_newline): Rename from scan_buffer.
958 Omit first arg TARGET, as it's always '\n'. All callers changed.
960 Clean up read_key_sequence a tiny bit more.
961 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
962 (read_key_sequence): Remove unused locals.
964 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
966 Clean up read_key_sequence a bit; reread active keymaps after first event.
967 * keyboard.c (read_char, read_char_x_menu_prompt)

969 Replace nmaps+maps with a single `map' arg.
970 (follow_key): Operate on a single map.
971 (active_maps): New function.
972 (test_undefined): Also return true for nil bindings.
973 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
974 a single (composed) keymap. Remember `first_event' to choose the right
975 set of active keymaps. Recompute the set of keymaps after receiving
976 the first event. Remove GOBBLE_FIRST_EVENT.
977 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
978 * keyboard.h (read_char): Update declaration.
979 * lread.c (read_filtered_event): Adjust call to read_char.

985 in the window. (Bug#13675)
987 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
989 * marker.c (set_marker_internal): If desired position is passed

998 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1000 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1001 When text lines are longer than window's screen lines, don't move back
1002 too far. This speeds up some redisplay operations. (Bug#13675)

1018 (sxhash_float): Return EMACS_UINT, for consistency with the other
1020 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1021 non-static inline function and therefore can't use static vars.
1022 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1023 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1024 with the other hash functions.
1026 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1028 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1029 XXXXXX part of the temporary file pattern is not downcased even
1030 when w32-downcase-file-names is non-nil. (Bug#13661)
1032 * xdisp.c (decode_mode_spec): Remove handling of %t.
1034 * msdos.c (careadlinkatcwd): Remove.
1036 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1038 * lread.c (skip_dyn_bytes): New function (bug#12598).

1079 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1081 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1084 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.

1092 if isFullscreen returns YES.
1093 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1094 (check_native_fs): New function.

1111 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1112 (syms_of_nsterm): Add ns-use-native-fullscreen.
1114 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1116 * fileio.c (Qchoose_write_coding_system): Now static.
1118 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1120 * xdisp.c (window_buffer_changed): region_showing can be negative,
1121 which still means region is being displayed.
1122 (redisplay_internal): Resurrect code that forced redisplay of the
1123 whole window when showing region and the mark has changed.
1124 Record the new mark position to allow redisplay optimizations.
1125 (display_line): If it->region_beg_charpos is non-zero, set the
1126 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1128 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1129 not bitfield of 1 bit.
1131 2013-02-03 Daniel Colascione <dancol@dancol.org>
1133 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1134 daemon mode works on cygw32 when Emacs is installed and not just
1137 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1139 Avoid file time stamp bug on MS-Windows (Bug#13149).
1140 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1141 as FAT32 doesn't update time stamps when truncating them.
1142 Also, check that a file time stamp is not a multiple of 100 ns;
1143 this should catch all instances of the problem on MS-Windows,
1144 as its native file system resolution is 100 ns or worse, and
1145 checking for a non-multiple of 100 ns should impose only a small
1146 overhead on systems with ns resolution.
1148 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1150 Avoid encoding file names on MS-Windows when they need to be run
1151 through dostounix_filename.
1152 * w32.c (normalize_filename): Accept an additional argument
1153 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1154 downcase it even if w32-downcase-file-names is non-nil.
1155 (dostounix_filename): Accept an additional argument MULTIBYTE and
1156 pass it to normalize_filename.
1157 (emacs_root_dir): Adjust.
1159 * msdos.h (dostounix_filename): Adjust prototype.
1161 * w32.h (dostounix_filename): Adjust prototype.
1163 * msdos.c (dostounix_filename): Accept an additional argument and
1165 (init_environment): Adjust callers of dostounix_filename.
1167 * fileio.c (Ffile_name_directory, file_name_as_directory)
1168 (directory_file_name, Fexpand_file_name)
1169 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1171 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1173 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1174 variables, as egetenv is case-insensitive for DOS_NT.
1176 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1177 with an encoded file name.
1179 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1180 Adjust calls to dostounix_filename.
1182 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1184 * unexw32.c (unexec): Adjust call to dostounix_filename.
1186 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1188 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1191 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1194 * callproc.c (Fcall_process): Make sure program name in PATH and
1195 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1196 is passed to exec/spawnve, which fails unless the file-name
1199 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1200 even if w32-quote-process-args is nil.
1202 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1204 Fix timestamp bug when write-region appends nothing (Bug#13149).
1205 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1206 the file's time stamp doesn't change if Emacs happens to write nothing
1207 to the file, and on a buggy file system this could cause Emacs to
1208 incorrectly infer that the file system doesn't have the bug.
1209 Avoid this problem by inhibiting the inference in this case.
1211 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1213 * window.h (struct window): Convert base_line_number, base_line_pos
1214 and column_number_displayed members from Lisp_Object to ptrdiff_t.

1224 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1225 (try_scrolling, try_cursor_movement, redisplay_window)
1226 (try_window_reusing_current_matrix, try_window_id, display_line)
1227 (display_mode_lines, decode_mode_spec): Adjust users.
1228 * .gdbinit (pwinx): Do not print sequence_number.
1230 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1232 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1233 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1234 * dired.c: Include <fcntl.h>.
1235 (open_directory): New function, which uses open and fdopendir
1236 rather than opendir. DOS_NT platforms still use opendir, though.

1239 (directory_files_internal, Ffile_attributes): Use it.
1240 (file_attributes, file_name_completion_stat): First arg is now fd,
1241 not dir name. All uses changed. Use fstatat rather than lstat +

1244 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1245 (emacs_readlinkat): New function, with much of the old
1246 Ffile_symlink_p, but with an fd argument for speed.
1247 It uses readlinkat rather than careadlinkatcwd, so that it
1248 need not assume the working directory.
1249 (Ffile_symlink_p): Use it.
1250 * filelock.c (current_lock_owner): Use emacs_readlinkat
1251 rather than emacs_readlink.
1252 * lisp.h (emacs_readlinkat): New decl.
1253 (READLINK_BUFSIZE, emacs_readlink): Remove.
1254 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1255 (emacs_norealloc_allocator, emacs_readlink): Remove.
1256 This stuff is moved to fileio.c.
1257 * w32.c (fstatat, readlinkat): New functions.
1258 (careadlinkat): Don't check that fd == AT_FDCWD.

1275 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1276 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1279 * w32.c (w32_get_long_filename, init_environment, readlink):
1280 Support file names encoded in DBCS codepages.
1281 (readlink): Use the current file-name-coding-system, not the ANSI
1282 codepage, to decode and handle targets of symlinks.
1284 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1286 * w32.c (opendir): Now accepts a 'const char *'.
1288 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>

1300 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1302 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>

1305 debugging code. Adjust comment style here and there.
1306 * insdel.c (insert_1): Remove.
1307 * lisp.h (insert_1): Remove prototype.
1308 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1310 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1312 * w32.c (max_filename_mbslen): New function.
1313 (normalize_filename, readdir): Use it to detect locales where ANSI
1314 encoding of file names uses a double-byte character set (DBCS).
1315 If a DBCS encoding is used, advance by characters using
1316 CharNextExA, instead of incrementing a 'char *' pointer.
1317 Use _mbslwr instead of _strlwr. (Bug#13515)
1319 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial

1356 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1358 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1360 * xdisp.c (message2, message2_nolog): Remove functions.
1361 (message3, message3_nolog): Extract nbytes and multibyteness directly
1362 from the string. Change all callers.
1363 (message3_nolog): Don't set message_enable_multibyte since set_message
1364 will reset it anyway.
1365 (message1, message1_nolog): Use message3.
1366 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1367 (with_echo_area_buffer): Remove last two arguments. Update all callers.

1413 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1415 * xdisp.c (mark_window_display_accurate): Simplify the loop
1416 assuming that the only one of vchild, hchild or buffer window
1417 slots is non-nil. Call mark_window_display_accurate_1 for
1418 the leaf windows only.
1419 (mark_window_display_accurate_1): Always assume leaf window.
1422 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1424 * emacs.c (Qkill_emacs_hook): Now static.
1426 * fileio.c (Finsert_file_contents): Simplify.
1427 Remove unnecessary assignments and tests.
1429 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1431 * w32.c (acl_set_file): Don't test for errors unless
1432 set_file_security returns FALSE. Avoids spurious errors when
1435 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1437 * fileio.c (Finsert_file_contents): Revert code introduced at
1438 2013-01-18 in favor of the simpler and generally better fix.
1439 Save stack space by removing 'buffer' and reusing 'read_buf'
1442 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1444 * lisp.h (eabs): Define unconditionally (Bug#13419).
1445 The old "#if !defined (eabs)" was an unnecessary revenant of back
1446 when this macro was called "abs". Document 'eabs' better.
1448 2013-01-19 Glenn Morris <rgm@gnu.org>
1450 * fns.c (Frandom): Doc fix.
1452 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1454 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1455 segfault when there are lots of overlays.
1457 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1458 when there are lots of overlays.
1459 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1460 for the details and a way to reproduce.
1462 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1464 * fileio.c: Use O_APPEND to append.
1465 This corresponds better to the natural interpretation of "append",
1466 and avoids the need to open the output file twice, or to invoke
1467 lseek when APPEND is neither nil nor a number.
1468 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1469 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1470 file possibly twice, and lseeking to its end; this avoids the
1471 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1472 at the same time: the combination is never needed and apparently
1473 it doesn't work with DOS_NT.
1475 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1476 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1478 Allow floating-point file offsets.
1479 Problem reported by Vitalie Spinu in
1480 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1481 * fileio.c (emacs_lseek): Remove.
1482 (file_offset): New function.
1483 (Finsert_file_contents, Fwrite_region): Use it.
1485 2013-01-19 Chong Yidong <cyd@gnu.org>
1487 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1488 aborting on Fsignal (Bug#13289).
1490 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1492 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1493 set_file_security as failure due to insufficient privileges.
1494 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1495 (fstat): Return owner and group like 'stat' and 'lstat' do.
1497 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1499 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1500 The bug was observed on Ubuntu operating inside a virtual machine,
1501 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1502 The workaround introduces a race condition on non-buggy hosts,
1503 but it's an unlikely race and anyway there's a nearly identical
1504 nearby race that can't be fixed.
1505 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1507 (Fwrite_region): Test for file system time stamp bug.
1508 (init_fileio): New function.
1509 * lisp.h (init_fileio): Declare it.
1510 * emacs.c (main): Call it.
1512 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1513 and make it more consistent with other stat-failure diagnostics.
1515 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1517 Fix crash when inserting data from non-regular files.
1518 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1519 for the error description produced by valgrind.
1520 * fileio.c (read_non_regular): Rename to read_contents.
1521 Free Lisp_Save_Value object used to pass parameters.
1522 (read_non_regular_quit): Rename to read_contents_quit.
1523 (Finsert_file_contents): Redesign internal file reading loop to adjust
1524 gap and end positions after each read and so help make_gap to work
1525 properly. Do not signal an I/O error too early and so do not leave
1526 not yet decoded characters in a buffer, which was the reason of
1527 redisplay crash. Use list2 to build return value. Adjust comments.
1529 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1531 Close a race when statting and reading files (Bug#13149).
1532 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1533 This avoids a race if the file is renamed between stat and open.
1534 This race is not the problem originally noted in Bug#13149;
1535 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1537 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

1544 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1545 * alloc.c (format_save_value): Rename to make_save_value.
1546 (make_save_pointer): New function.
1547 (record_xmalloc): Use make_save_pointer.
1548 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1549 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1550 Change users of make_save_value to make_save_pointer.
1551 Likewise for format_save_value and make_save_value.

1560 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
1562 * alloc.c (free_save_value): Now static.
1564 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1566 * keymap.c (map_keymap_internal): Use format_save_value.
1567 (map_keymap_char_table_item): Adjust accordingly.
1568 * fileio.c (non_regular_fd, non_regular_inserted)
1569 (non_regular_nbytes): Remove.
1570 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1571 Use format_save_value to pass parameters to read_non_regular.
1572 (read_non_regular): Use XSAVE_ macros to extract parameters.
1574 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1576 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1578 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1580 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1581 extraction from any Lisp_Save_Value slot. Add type checking.
1582 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1583 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1584 * xselect.c: All users changed.
1586 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

1594 object with the specified internal structure.
1595 (make_save_value): Reimplement using format_save_value.
1596 * editfns.c (save_excursion_save): Use format_save_value.
1597 (save_excursion_restore): Use XSAVE_OBJECT.
1599 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1601 Avoid needless casts with XSAVE_POINTER.
1602 * alloc.c (mark_object) [GC_MARK_STACK]:
1603 * dired.c (directory_files_internal_unwind):
1604 * fileio.c (do_auto_save_unwind):
1605 * gtkutil.c (pop_down_dialog):
1606 * keymap.c (map_keymap_char_table_item):
1607 * lread.c (load_unwind):
1608 * nsmenu.m (pop_down_menu):
1609 * print.c (print_object) [GC_MARK_STACK]:
1610 * xfns.c (clean_up_file_dialog):
1611 * xmenu.c (cleanup_widget_value_tree):
1612 Omit casts between XSAVE_POINTER and a pointer type.
1614 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>

1617 * eval.c (eval_sub): Protect `form' from being GCed before its
1618 car and cdr becomes protected with the backtrace entry.
1620 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1622 Make Lisp_Save_Value more versatile storage for up to four objects.

1632 (free_save_value): Likewise.
1633 (mark_object): Likewise.
1634 * editfns.c (save_excursion_save): Pack everything within
1635 Lisp_Save_Value and so avoid xmalloc.
1636 (save_excursion_restore): Adjust to match new layout. Use free_misc
1637 because we do not allocate extra memory any more. Add eassert.
1638 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1639 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
1640 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
1641 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

1647 (nsfont_draw): Remove disabling of LCD smoothing.
1648 (ns_glyph_metrics): Add LCD_SMOOTHING_MARGIN to bearings to fix
1649 Bug#11484 with LCD smoothing on.
1651 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
1653 Fix SIGDANGER handlers, for AIX (Bug#13408).
1654 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
1655 Move handlers here from emacs.c; they were out of place.
1657 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
1659 * xterm.c (syms_of_xterm): Adjust documentation for

1691 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
1692 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
1693 Clear tzvalbuf_in_environ if this workaround is in effect.
1694 Problem and fix reported by Kazuhiro Ito.
1696 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>

1707 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1709 Avoid unnecessary byte position calculation for the gap movement.
1710 Since all users of move_gap do CHAR_TO_BYTE for other purposes
1711 anyway, all of them should use move_gap_both instead.
1712 * lisp.h (move_gap): Remove prototype.
1713 * insdel.c (move_gap): Remove.
1714 (move_gap_both): Add eassert.

1721 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1723 * term.c (init_tty): Use them instead of rolling our own code.
1724 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1725 switches from 'signal' to 'pthread_sigmask', which is safer in
1726 multithreaded applications.
1727 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1728 which has already arranged for that.
1729 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.

1739 Omit buffer_slot_type_mismatch and use generic predicates to enforce
1740 the type of per-buffer values where appropriate.
1741 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
1742 predicate, which is how it's really used now. Adjust comment.
1743 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1744 * buffer.c (buffer_slot_type_mismatch): Remove.
1745 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

1750 right-fringe-width, scroll-bar-width and buffer-display-count.
1751 Use Qstringp for default-directory, buffer-file-name,
1752 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1753 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1755 * data.c (store_symval_forwarding): Adjust to call the predicate.
1757 2013-01-09 Juanma Barranquero <lekktu@gmail.com>

1772 (make_gap_1): New function to adjust the gap of any buffer.
1773 * coding.c (coding_alloc_by_making_gap): Use it.
1774 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
1775 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.

1798 trailing dash is properly added.
1800 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1802 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1803 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1804 digits for buffer positions, before misalignment starts.
1805 Display "0" for integer "object" field.
1806 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1807 Display the newline glyph more unambiguously.

1869 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
1871 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1872 (xg_update_menubar): Update title only if
1873 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1874 (xg_update_submenu): Skip tearoff only if
1875 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1876 (xg_initialize): Initialize xg_detached_menus only if
1877 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
1879 * xterm.h (struct x_output): Surround handlebox_widget with
1880 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
1881 toolbar_in_hbox is bool.
1883 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
1885 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
1886 (LIBS_GNUSTEP): Define.
1887 (LIBES): Add $(LIBS_GNUSTEP).
1888 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
1890 2012-12-30 Eli Zaretskii <eliz@gnu.org>
1892 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
1893 continuation glyph on a TTY with an indication of an empty line.
1896 2012-12-29 Eli Zaretskii <eliz@gnu.org>
1898 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
1899 file's SELinux context or ACLs successfully set, nil otherwise.
1901 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
1903 * w32proc.c (reader_thread): Avoid passing NULL handles to
1904 SetEvent and WaitForSingleObject.
1906 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
1908 Port EXTERNALLY_VISIBLE to Clang 3.2.
1909 * conf_post.h (__has_attribute): New macro.
1910 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
1912 2012-12-27 Glenn Morris <rgm@gnu.org>
1914 * cygw32.c (Fcygwin_convert_file_name_to_windows)
1915 (Fcygwin_convert_file_name_from_windows): Doc fixes.
1917 2012-12-27 Eli Zaretskii <eliz@gnu.org>
1919 * fileio.c (file_name_as_directory, directory_file_name):
1920 Accept an additional argument MULTIBYTE to indicate whether the input C
1921 came from a multibyte or a unibyte Lisp string; all callers
1922 adjusted. Don't assume the input string is always multibyte.
1924 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
1925 don't ENCODE_FILE them, and return a unibyte string if the input
1927 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
1928 don't assume the input strings will always be multibyte. If the
1929 input strings are multibyte, decode strings obtained from C
1932 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1934 * lisp.h (toplevel): Add two notices to the comment about
1935 defining a new Lisp data type.
1936 * print.c (print_object): If Lisp_Save_Value object's pointer
1937 is the address of a memory area containing Lisp_Objects, try
1939 * alloc.c (valid_lisp_object_p): Adjust comment.
1941 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1943 * keyboard.c (record_asynch_buffer_change): Initialize an event
1944 only if it's really needed.
1945 * frame.h (enum output_method): Remove output_mac member since
1946 it's a leftover from the deleted code.
1947 * frame.c (Fframep): Adjust user here ...
1948 * terminal.c (Fterminal_live_p): ... and here.
1949 * coding.c (Qmac): Now here because it's only used to denote
1950 end-of-line encoding type.
1951 (syms_of_coding): DEFSYM it.
1952 * frame.h (Qmac): Remove duplicated declaration.
1954 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1956 * window.c (select_window_1): Now static, since it's used only here.
1958 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1960 * window.c (window_body_cols): Subtract display margins from the
1961 window body width on TTYs as well. See
1962 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1963 for the original report.
1965 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1967 * xdisp.c (redisplay_window): Remove inner local variable
1968 because the outer shadowed one has the same meaning.
1969 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1971 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1972 (xg_create_tool_bar): Adjust users.
1974 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1976 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1977 * buffer.c (Fget_buffer_create): Use it to set compact field of
1978 struct buffer_text to avoid accessing an uninitialized value
1979 when compact_buffer is called for the first time.
1980 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1981 (Fset_buffer_modified_p): Use buffer_window_count to check
1982 whether the buffer is displayed in some window.
1983 * xdisp.c (message_dolog): Likewise.
1985 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1987 * w32.c (acl_set_file): If setting the file security descriptor
1988 fails, and the new DACL is identical to the existing one, silently
1989 return success. This fixes problems for users backing up their
1990 own files without having the necessary privileges for setting
1991 security descriptors.
1993 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1995 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1996 after WaitForSingleObject returns normally. This expedites reader
1997 thread shutdown when delete_child triggers it.
1998 (reap_subprocess): More accurate commentary for why we call
1999 delete_child only when cp->fd is negative.
2001 * w32.c (sys_close): Do not call delete_child on a subprocess
2002 whose handle is not yet closed. Instead, set its file descriptor
2003 to a negative value, so that reap_subprocess will call
2004 delete_child on that subprocess when its SIGCHLD arrives.
2005 This avoids closing handles used for communications between sys_select
2006 and reader_thread, which doesn't give sys_select a chance to
2007 notice that the process exited and invoke the SIGCHLD handler for
2010 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2012 * nsfns.m (Fns_do_applescript): Run event loop until script has
2013 been executed (Bug#12969).
2014 (ns_run_ascript): Chech as_script for nil, set to nil after
2017 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2019 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2021 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2023 * w32term.c (w32fullscreen_hook): New function.
2024 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2026 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2028 * fileio.c (Finsert_file_contents): Doc fix.
2030 * w32proc.c (new_child, delete_child, find_child_pid): For a
2031 subprocess, consider its slot being in use as long as its process
2032 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2033 slot when a new process is started immediately after killing
2034 another one, without waiting enough time for the first process to
2035 be reaped and resources allocated for it be orderly freed.
2037 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2039 2012-12-21 Chong Yidong <cyd@gnu.org>
2041 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2043 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2045 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2047 * w32.c (get_name_and_id): Always pass NULL as the first argument
2048 of lookup_account_sid. Avoids crashes with UNC file names that
2049 refer to DFS domains, not to specific machine names. (Bug#12621)
2050 Remove now unused argument FNAME; all callers changed.
2051 (get_file_owner_and_group): Remove now unused argument FNAME; all
2054 2012-12-21 Chong Yidong <cyd@gnu.org>
2056 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2057 error for invalid chars, don't check for a nil return value.
2059 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2061 Avoid calls to CHAR_TO_BYTE if byte position is known.
2062 * editfns.c (make_buffer_string_both): Use move_gap_both.
2063 (Fbuffer_string): Use make_buffer_string_both.
2064 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2066 (buf_bytepos_to_charpos): Likewise.
2067 (charpos_to_bytepos): Remove.
2068 * fileio.c (Finsert_file_contents): Use move_gap_both.
2069 * search.c (Freplace_match): Likewise.
2070 * process.c (process_send_region): Likewise. Use convenient
2071 names for byte positions.
2072 * lisp.h (charpos_to_bytepos): Remove prototype.
2073 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2074 * insdel.c (move_gap): Likewise.
2076 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2078 * xdisp.c (redisplay_internal): Remove now-unused local.
2080 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2082 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2083 (redisplay_internal): Don't bother selecting the frame to get the
2084 proper value of frame-local variables (bug#13225).
2086 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2088 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2089 Rename 4th argument since it may be buffer or string. Adjust comment.
2090 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2092 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2094 * coding.c (Fdetect_coding_region): Do not check start and end with
2095 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2096 (code_convert_region): Likewise.
2098 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2100 * w32.c (acl_get_file, acl_set_file): Run the file name through
2101 map_w32_filename, and resolve any symlinks in the file name, like
2103 (acl_set_file): Call revert_to_self, if any privileges were
2106 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2108 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2109 ($(BLD)/w32.$(O)): Update dependencies.
2111 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2113 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2114 propagate redisplay's scrolling (if any) to the right window.
2115 (redisplay_internal): Use ensure_selected_frame.
2116 (display_mode_lines): Complete last fix.
2117 * window.c (select_window_1): New func, extracted from select_window.
2118 (select_window): Use it.
2119 * window.h (select_window_1): Declare.
2121 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2123 Emulate Posix ACL APIs on MS-Windows.
2124 * w32.c: Include sddl.h and sys/acl.h.
2125 (SDDL_REVISION_1): Define if not already defined.
2126 (g_b_init_get_security_descriptor_dacl)
2127 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
2128 (g_b_init_is_valid_security_descriptor)

2141 (acl_free, acl_get_file, acl_set_file): New functions.
2143 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
2145 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2147 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2148 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2149 for some of that bug's symptoms can now cause Emacs to abort.
2150 Remove the workaround.
2151 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2152 The bug that caused SIGCHLD to get lost has been fixed, and the
2153 workaround for it can now cause Emacs to abort.
2155 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2157 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2158 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2159 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
2161 2012-12-16 Romain Francoise <romain@orebokech.com>
2163 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2164 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2165 and copy ACL entries of file in addition to SELinux context if set.
2166 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2168 * Makefile.in (LIBACL_LIBS): New macro.
2171 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
2173 * fileio.c (internal_delete_file): Use bool for boolean.
2175 2012-12-15 Eli Zaretskii <eliz@gnu.org>
2177 Fix bug #13079 on MS-Windows with temp files not being deleted.

2180 (register_child): First argument is now pid_t.
2181 (record_infile, record_pending_deletion): New prototypes.
2183 * w32proc.c (new_child): Initialize input_file and
2184 pending_deletion members of the child.
2185 (delete_child): Delete the child's temporary input file, if any,
2186 that is pending deletion.
2187 (register_child): First argument is now pid_t.
2188 (record_infile, record_pending_deletion): New functions.
2189 (reap_subprocess): Fix a typo in DebPrint string.
2190 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2192 * fileio.c (internal_delete_file): Return an int again: non-zero
2193 if delete-file succeeds, zero otherwise.
2195 * lisp.h (internal_delete_file): Adjust prototype.
2197 * callproc.c (Fcall_process): Don't overwrite infile with result
2199 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2200 asynchronous subprocess, record the name of the input file name,
2202 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2203 delete the file, record it as pending deletion when the subprocess
2206 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2208 * editfns.c [HAVE_PWD_H]: Include grp.h.
2210 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
2212 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
2214 Fix permissions bugs with setgid directories etc. (Bug#13125)
2215 * dired.c (Ffile_attributes): Return t as the 9th attribute,
2216 to mark it as a placeholder. The old value was often wrong.
2217 The only user of this attribute has been changed to use
2218 file-ownership-preserved-p instead, with its new group arg.
2219 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
2221 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

2226 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2228 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2229 try to get accurate owner and group information from NT file
2230 security APIs. This is to make most callers of 'stat' and
2231 'lstat', which don't need that information, much faster.
2233 * dired.c (Ffile_attributes) [WINDOWSNT]:
2234 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2235 owner and group information from 'lstat'.
2237 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2239 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2240 as that confuses set-auto-coding, so insist on the head-read
2241 returning the full 1024 bytes. Let lseek compute the tail offset;
2242 less work for us. Do not ignore I/O errors when reading the tail.
2244 * xdisp.c: Minor style fixes.
2245 (init_iterator): Hoist assignment out of if-expression.
2246 (markpos_of_region): Callers now test for sign, not for -1.
2248 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
2250 Minor redisplay optimization when the region length is zero.
2251 * xdisp.c (markpos_of_region): New function.
2252 (init_iterator): Do not highlight the region of zero length.
2253 (redisplay_window): Check whether the region is of non-zero length.
2254 (try_cursor_movement): Allow if the region length is zero.
2255 (try_window_reusing_current_matrix, try_window_id): Likewise.
2257 2012-12-13 Eli Zaretskii <eliz@gnu.org>
2259 * search.c (search_buffer): Check the inverse translations of each
2260 character in pattern when the buffer being searched is unibyte.
2263 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2265 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2266 files, fixing a regression from 24.2.
2267 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2269 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2271 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2272 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2273 Remove unnecessary S_ISLNK test, as (contra the comments) this
2274 function can't copy symlinks. Improve quality of error message
2275 when attempting to copy files that are neither regular files nor
2278 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
2280 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.

2282 * window.c (Frecenter):
2283 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
2284 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
2286 2012-12-12 Daniel Colascione <dancol@dancol.org>
2288 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2289 the dumped Emacs is not a sparse file, greatly improving Cygwin
2290 "make bootstrap" performance.
2292 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
2294 * inotify.c (inotify_callback): Generate an Emacs event for every
2295 incoming inotify event.
2297 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2299 * xdisp.c (handle_face_prop): Fix logic of computing
2300 it->start_of_box_run_p.
2301 (append_space_for_newline): If the glyph row is R2L, reset the
2302 iterator's end_of_box_run_p flag before prepending the space glyph.
2303 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2304 iterator's start_of_box_run_p flag before prepending the stretch.
2305 (append_glyph, produce_image_glyph, append_composite_glyph)
2306 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2307 left_box_line_p and right_box_line_p flags of the glyph for R2L
2308 glyph rows. (Bug#13011)
2310 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2312 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
2313 if changed buffer is not shown in a window.
2314 * insdel.c (prepare_to_modify_buffer): Likewise.
2315 * window.c (replace_buffer_in_windows_safely): Do nothing
2316 if buffer is not shown in a window.
2317 (Fforce_window_update): Likewise if string or buffer argument
2320 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2322 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
2323 encoded_file_name, which is what it is.
2325 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2327 Consistently use marker_position and marker_byte_position.
2328 * fringe.c (Ffringe_bitmaps_at_pos):
2329 * indent.c (Fvertical_motion):
2330 * insdel.c (prepare_to_modify_buffer):

2335 * xdisp.c (message_dolog, with_echo_area_buffer_unwind_data)
2336 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
2337 Replace direct access to marker fields with calls
2338 to marker_position and/or marker_byte_position.

2473 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
2474 DWORD_PTR, for compatibility with 64-bit builds.

2502 * w32.c (unsetenv): Return 0 if the input string is too long.
2504 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2506 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).

2508 * dbusbind.c (Fdbus_init_bus):
2510 * xterm.c (x_term_init):

2518 instead, use xputenv+unsetenv to set and restore TZ.
2519 (environbuf): Remove static var. All uses removed.
2520 (Fset_time_zone_rule): Do not save TZ and environ;
2521 no longer needed here.
2522 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
2523 Move to inside set_time_zone_rule; they don't need file scope any more.
2524 (set_time_zone_rule): Maintain the TZ=value string separately.
2525 (syms_of_editfns): Don't initialize initial_tz;
2526 init_editfns now does it.
2527 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
2528 * lisp.h (xputenv): New decl.
2530 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
2532 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
2534 2012-12-08 Eli Zaretskii <eliz@gnu.org>
2536 * w32.c (unsetenv, sys_putenv): New functions.

2541 informative (Bug#12992).
2543 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2545 Simplify get_lim_data.
2546 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2547 Remove USG and vlimit methods; no longer used these days.
2548 Add #error catchall just in case.
2550 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2551 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2552 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
2553 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
2554 (deleted_pid_list, Fdelete_process, create_process)
2555 (record_child_status_change, handle_child_signal, deliver_child_signal)
2556 (init_process_emacs, syms_of_process):
2557 Assume SIGCHLD is defined.

2559 (abbr_to_signal): New static function.
2560 (Fsignal_process): Use it to convert signal names to ints.
2561 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
2562 kill (getpgrp (), ...).

2567 All uses replaced by 'kill' with a negative pid.
2568 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
2569 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
2571 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
2573 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
2574 This will cause a production Emacs to dump core instead of
2577 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2579 * frame.c (make_frame): Do not set window's buffer to t.
2580 * window.c (Fsplit_window_internal): Likewise. Previously it was
2581 used to indicate that the window is being set up. Now we use
2582 set_window_buffer for all new windows, so the condition in ...
2583 (Fset_window_buffer): ... is always true and can be removed.
2585 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2587 Convenient macro to check whether the buffer is hidden.
2588 * buffer.h (BUFFER_HIDDEN_P): New macro.
2589 * frame.c (make_frame): Use it. Adjust comment.
2590 * buffer.c (candidate_buffer): New function.
2591 (Fother_buffer, other_buffer_safely): Use it.
2593 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2595 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2596 if the child process is still running. Instead, exit the wait
2597 loop and return zero. (Bug#13086)
2599 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2601 * frame.h (x_char_width, x_char_height): Remove prototypes.
2602 * w32term.h (x_char_width, x_char_height): Likewise.

2615 * callproc.c, process.h (record_kill_process):
2616 New function, containing part of the old call_process_kill.
2617 (call_process_kill): Use it.
2618 This does not change call_process_kill's behavior.
2619 * process.c (Fdelete_process): Use record_kill_process to fix a
2620 race condition that could cause Emacs to lose track of a child.
2622 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2624 Avoid code duplication between prev_frame and next_frame.
2625 * frame.c (candidate_frame): New function. Add comment.
2626 (prev_frame, next_frame): Use it. Adjust comment.
2628 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2630 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2631 fails, signal an error instead of continuing with an empty
2633 Encode expanded temp file pattern before passing it to mkstemp or
2636 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2637 Encode the file name before passing it to dostounix_filename, in
2638 case it will downcase it (under w32-downcase-file-names).
2641 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2643 Minor call-process cleanups.
2644 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2645 at the same time as other platforms, to simplify analysis.
2646 No need for fd0_volatile since we have synch_process_fd.
2647 Avoid needless emacs_close; arg is always negative.
2649 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2651 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2654 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2656 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2657 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2658 and mouse_face_hidden members to a bitfields.

2660 (FRAME_SPACE_WIDTH): Remove.
2661 * nsterm.m, w32term.c, xterm.c: Adjust users.
2662 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2663 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2664 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2665 members to a bitfields.
2667 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2669 Don't let call-process be a zombie factory (Bug#12980).
2670 Fixing this bug required some cleanup of the signal-handling code.
2671 As a side effect, this change also fixes a longstanding rare race
2672 condition whereby Emacs could mistakenly kill unrelated processes,
2673 and it fixes a bug where a second C-g does not kill a recalcitrant
2674 synchronous process in GNU/Linux and similar platforms.
2675 The patch should also fix the last vestiges of Bug#9488,
2676 a bug which has mostly been fixed on the trunk by other changes.
2677 * callproc.c, process.h (synch_process_alive, synch_process_death)
2678 (synch_process_termsig, sync_process_retcode):
2679 Remove. All uses removed, to simplify analysis and so that
2680 less consing is done inside critical sections.
2681 * callproc.c (call_process_exited): Remove. All uses replaced
2682 with !synch_process_pid.
2683 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2684 These take the role of what used to be in unwind-protect arg.
2686 (block_child_signal, unblock_child_signal):
2687 New functions, to avoid races that could kill innocent-victim processes.
2688 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2689 (call_process_kill): Record killed processes as deleted, so that
2690 zombies do not clutter up the system. Do this inside a critical
2691 section, to avoid a race that would allow the clutter.
2692 (call_process_cleanup): Fix code so that the second C-g works again
2693 on common platforms such as GNU/Linux.
2694 (Fcall_process): Create the child process in a critical section,
2695 to fix a race condition. If creating an asynchronous process,
2696 record it as deleted so that zombies do not clutter up the system.
2697 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2698 light of these changes. Omit unnecessary call to emacs_close
2699 before failure, as the unwind-protect code does that.
2700 * callproc.c (call_process_cleanup):
2701 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2702 * process.c (record_deleted_pid): New function, containing
2703 code refactored out of Fdelete_process.
2704 (Fdelete_process): Use it.
2705 (process_status_retrieved): Remove. All callers changed to use
2706 child_status_change.
2707 (record_child_status_change): Remove, folding its contents into ...
2708 (handle_child_signal): ... this signal handler. Now, this
2709 function is purely a handler for SIGCHLD, and is not called after
2710 a synchronous waitpid returns; the synchronous code is moved to
2711 wait_for_termination. There is no need to worry about reaping
2712 more than one child now.
2713 * sysdep.c (get_child_status, child_status_changed): New functions.
2714 (wait_for_termination): Now takes int * status and bool
2715 interruptible arguments, too. Do not record child status change;
2716 that's now the caller's responsibility. All callers changed.
2717 Reimplement in terms of get_child_status.
2718 (wait_for_termination_1, interruptible_wait_for_termination):
2719 Remove. All callers changed to use wait_for_termination.
2720 * syswait.h: Include <stdbool.h>, for bool.
2721 (record_child_status_change, interruptible_wait_for_termination):
2723 (record_deleted_pid, child_status_changed): New decls.
2724 (wait_for_termination): Adjust to API changes noted above.
2726 * bytecode.c, lisp.h (Qbytecode): Remove.
2727 No longer needed after 2012-11-20 interactive-p changes.
2729 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2731 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2732 the scroll margin, move point outside the margin. (Bug#13055)
2734 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2736 * gtkutil.c (my_log_handler): New function.
2737 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2739 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2741 * lisp.h (modify_region): Rename to...
2742 (modify_region_1): ...new prototype.
2743 * textprop.c (modify_region): Now static. Adjust users.
2744 * insdel.c (modify_region): Rename to...
2745 (modify_region_1): ...new function to work with current buffer.
2746 Adjust comment and users. Use true and false for booleans.
2748 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2750 * alloc.c (free_save_value): New function.
2751 (safe_alloca_unwind): Use it.
2752 * lisp.h (free_save_value): New prototype.
2753 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2755 (save_excursion_restore): Adjust to match saved data structure.
2756 Use free_save_value to offload some work from GC. Drop obsolete
2759 2012-12-03 Chong Yidong <cyd@gnu.org>
2761 * fileio.c (Vauto_save_list_file_name): Doc fix.
2763 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2765 * w32fns.c: Remove prototype of atof.
2766 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2768 (file_dialog_callback): Make it UINT_PTR.
2770 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2773 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2774 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2777 2012-12-03 Glenn Morris <rgm@gnu.org>
2779 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2781 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2783 Fix xpalloc confusion after memory is exhausted.
2784 * alloc.c (xpalloc): Comment fix.
2785 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2786 and signals an error, do not clear charset_table_size, as
2787 charset_table is still valid.
2788 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2790 Use execve to avoid need to munge environ (Bug#13054).
2791 * callproc.c (Fcall_process):
2792 * process.c (create_process):
2793 Don't save and restore environ; no longer needed.
2794 * callproc.c (child_setup):
2795 Use execve, not execvp, to preserve environ.
2797 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2799 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2801 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2803 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2804 display for sliced images (Bug#10500).
2806 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.

2810 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2811 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2813 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2815 * xdisp.c (window_outdated): Remove eassert since it hits
2816 some suspicious corner cases (see Bug#13007 and Bug#13012).
2817 (mode_line_update_needed): New function.
2818 (redisplay_internal, redisplay_window): Use it.
2819 (ensure_selected_frame): New function.
2820 (redisplay_internal, unwind_redisplay): Use it.
2821 (redisplay_internal): Move comment about buffer_shared...
2822 (buffer_shared_and_changed): ...near to its real use.
2824 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2826 * callproc.c (Fcall_process): Don't misreport vfork failure.
2828 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2830 * callproc.c (Fcall_process): Fix vfork portability problems.
2831 Do not assume that fd[0], count, filefd, and save_environ survive
2832 vfork. Fix bug whereby wrong errno value could be reported for
2833 pipe failure. Some minor cleanups, too, as follows. Move buf and
2834 bufsize to the context where they're needed. Change new_argv to
2835 be of type char **, as this is more convenient and avoids casts.
2836 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2837 Now local constants, not macros.
2839 2012-11-18 Kenichi Handa <handa@gnu.org>
2841 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
2842 for the variable "f".
2844 2012-11-13 Kenichi Handa <handa@gnu.org>
2846 * font.c (font_unparse_xlfd): Exclude special characters from the
2847 generating XLFD name.
2849 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
2851 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
2852 * dired.c (stat_uname, stat_gname):
2853 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
2855 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

2859 * fileio.c (Fcopy_file): Assume EISDIR is defined.
2860 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
2861 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
2862 * lread.c (readbyte_from_file): Assume EINTR is defined.
2863 * process.c (wait_reading_process_output, send_process) [subprocesses]:
2864 Assume EIO and EAGAIN are defined.
2865 * unexcoff.c (write_segment): Assume EFAULT is defined.
2867 2012-11-27 Eli Zaretskii <eliz@gnu.org>
2869 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
2872 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
2873 highlighting on the frame was cleared. Prevents assertion
2874 violations when repeatedly clicking on the "Top" link of the
2875 "bread-crumbs" in Info buffers.
2877 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
2879 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
2881 2012-11-24 Ken Brown <kbrown@cornell.edu>
2883 * keyboard.c (HAVE_MOUSE):
2884 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2885 were always defined.
2887 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2889 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2890 between bpos_covered and bpos_max. This fixes cursor display when
2891 several display strings follow each other.
2893 * .gdbinit (pgx): If the glyph's object is a string, display the
2894 pointer to string data, rather than the value of the string object
2895 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2897 * indent.c (Fvertical_motion): If the starting position is covered
2898 by a display string, return to one position before that, to avoid
2899 overshooting it inside move_it_to. (Bug#12930)
2901 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2903 * frame.h (struct frame): Remove display_preempted member
2904 since all users are dead long ago.
2905 * nsterm.h (struct x_output): Use the only dummy member.
2906 * w32menu.c (pending_menu_activation): Remove since not
2908 (set_frame_menubar): Adjust user.
2909 * w32term.h (struct x_output): Drop outdated #if 0 code.
2910 (struct w32_output): Use bitfields for explicit_parent,
2911 asked_for_visible and menubar_active members.
2912 Drop unused pending_menu_activation member.
2913 * xterm.h (struct x_output): Drop outdated #if 0 code.
2914 Use bitfields for explicit_parent, asked_for_visible,
2915 has_been_visible and net_wm_state_hidden_seen members.
2917 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2919 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2920 of a literal "/". (Bug#12955)
2921 (gl-stamp): Invoke fc.exe directly, not through cmd.
2923 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
2925 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2926 * dired.c: Assume HAVE_DIRENT_H.
2927 (NAMLEN): Remove, replacing with ...
2928 (dirent_namelen): New function. All uses changed. Use the GNU macro
2929 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2930 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2931 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2932 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2934 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2935 * ndir.h: Rename to ../nt/inc/dirent.h.
2936 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2937 Do not include <dirent.h>; no longer needed.
2938 * w32.c: Include <dirent.h> rather than "ndir.h".
2940 2012-11-23 Chong Yidong <cyd@gnu.org>
2942 * xftfont.c (xftfont_open): Remove duplicate assignment.
2944 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2946 * alloc.c (Fgarbage_collect): Unblock input after clearing
2947 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2948 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2949 * msdos.c (IT_frame_up_to_date): Use it here...
2950 * w32term.c (w32_frame_up_to_date): ...here...
2951 * xterm.c (XTframe_up_to_date): ...and here...
2952 * nsterm.m (ns_frame_up_to_date): ...but not here.
2953 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2955 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2956 Do not check whether GC is in progress.
2958 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2960 * xdisp.c (window_buffer_changed): New function.
2961 (update_menu_bar, update_tool_bar): Use it to
2962 simplify large 'if' statements.
2963 (redisplay_internal): Generalize commonly used
2964 'tail' and 'frame' local variables.
2966 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2968 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2969 with Windows system header.
2971 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2973 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2974 * alloc.c: Assume unistd.h exists.
2975 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
2976 * sysdep.c (get_current_dir_name): Assume getcwd exists.
2977 (getwd) [USG]: Remove; no longer needed.
2978 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2979 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2980 * w32.h (getcwd): Remove decl.
2982 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2984 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2985 Make it set selected_window as well.
2986 (update_tool_bar): Use it.
2988 2012-11-21 Ken Brown <kbrown@cornell.edu>
2990 * emacs.c (main): Set the G_SLICE environment variable for all
2991 Cygwin builds, not just GTK builds. See
2992 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2994 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2996 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2997 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2998 Define for the MSVC compiler.
3000 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3002 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3003 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3004 dostounix_filename. Prevents crashes down the road, because
3005 dostounix_filename assumes it gets a unibyte string.
3006 Reported by Michel de Ruiter <michel@sentient.nl>, see
3007 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
3009 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

3013 * lread.c (init_obarray): Set `function' fields to Qnil.
3014 * eval.c (Fcommandp): Ignore Qunbound.
3015 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
3016 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
3017 Test NILP rather than Qunbound.
3018 (Ffmakunbound): Set to Qnil.
3019 (Fsymbol_function): Never signal an error.
3020 (Finteractive_form): Ignore Qunbound.
3022 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3024 * eval.c (interactive_p): Remove no-longer-used decl.
3026 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3028 * xdisp.c (buffer_shared): Adjust comment.
3029 (buffer_shared_and_changed): New function.
3030 (prepare_menu_bars, redisplay_internal): Use it to
3031 decide whether all windows or frames should be updated.
3032 (window_outdated): New function.
3033 (text_outside_line_unchanged_p, redisplay_window): Use it.
3034 (redisplay_internal): Likewise. Fix indentation.
3036 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3038 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3039 (syms_of_eval): Remove corresponding defsubr.
3040 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3042 2012-11-19 Daniel Colascione <dancol@dancol.org>
3044 * w32fns.c (Fx_file_dialog):
3045 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3046 cygwin_convert_file_name*.
3048 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3049 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3051 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3053 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3055 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3057 * w32select.c: Include w32common.h before w32term.h, so that
3058 windows.h gets included before w32term.h uses some of its
3059 features, see below.
3061 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3063 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3065 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3067 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3069 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3070 (ns_select): Return at once if events are held (Bug#12834).
3072 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3074 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3075 Needed following 2012-10-20 change. (Bug#12902)
3077 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3079 * w32proc.c (waitpid): Remove unused label get_result.
3081 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3083 * makefile.w32-in (SYSWAIT_H): New macro.
3084 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3085 ($(BLD)/sysdep.$(O)): Update dependencies.
3087 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3089 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3090 * callproc.c (relocate_fd): Assume F_DUPFD.
3091 * emacs.c, term.c (O_RDWR): Remove.
3092 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3093 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3094 * nsterm.m: Assume <fcntl.h> exists.
3095 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3096 (create_pty, Fmake_network_process, server_accept_connection)
3097 (wait_reading_process_output, init_process_emacs):
3099 (wait_reading_process_output): Put in a special case for WINDOWSNT
3100 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3101 It's not clear this is needed, but it's a more-conservative change.
3102 (create_process): Assume FD_CLOEXEC.
3103 (create_process, create_pty): Assume O_NOCTTY.
3104 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3105 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3106 Omit if not DOS_NT, since F_GETFL is not defined there.
3107 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3108 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3110 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3111 lack it, since gnulib guarantees this.
3112 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3114 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3116 * w32.c (faccessat): Pretend that directories have the execute bit
3117 set. Emacs expects that, e.g., in files.el:cd-absolute.
3119 * w32proc.c (create_child): Don't clip the PID of the child
3120 process to fit into an Emacs integer, as this is no longer a
3122 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3123 reaping only the process specified by PID argument, if that is
3124 positive. Use PID instead of dead_child to know which process to
3125 reap. Wait for the child to die only if WNOHANG is not in
3127 (sys_select): Don't set dead_child.
3129 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3130 as it is no longer needed.
3132 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3134 (record_child_status_change): Remove the setting of
3135 record_at_most_one_child for the !WNOHANG case.
3137 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3139 Fix problems in ns port found by static checking.
3140 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3141 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3142 not to process group.
3143 (ns_select): Use emacs_write, not write, as that's more robust
3144 in the presence of signals.
3145 (fd_handler:): Check for read errors.
3147 2012-11-16 Glenn Morris <rgm@gnu.org>
3149 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3151 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3153 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3155 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3157 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3158 use the same value of thread handle.
3159 (start_timer_thread): If the timer thread exited (due to error),
3160 clean up by closing the two handles it used. Duplicate the caller
3161 thread's handle here, so it gets duplicated only once, when
3162 launching the timer thread. Set priority of the timer thread, not
3164 (getitimer): Don't duplicate the caller thread's handle here.
3167 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3169 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3172 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3174 Remove no-longer-used pty_max_bytes variable.
3175 * process.c (pty_max_bytes): Remove; unused.
3176 (send_process): Do not set it.
3178 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3180 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3181 Update dependencies.
3183 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3185 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3186 This follows up on the 2012-09-29 patch that removed indirection
3187 for the 'function' field. Reported by Sergey Vinokurov in
3188 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3190 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3192 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3193 different name, as the MS runtime does not have such a function,
3194 and probably never will.) All callers changed. Ignore DIRFD
3195 value if PATH is an absolute file name, to match Posix spec
3196 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3199 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3201 * xdisp.c (echo_area_display, redisplay_internal):
3202 Omit redundant check whether frame_garbaged is set.
3204 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3206 Use faccessat, not access, when checking file permissions (Bug#12632).
3207 This fixes a bug that has been present in Emacs since its creation.
3208 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3209 which must set some sort of record. (Torek's bug report was against
3210 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3211 same common flaw.) See Torek's Usenet posting
3212 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3213 Posted: Fri Apr 8 14:18:56 1983.
3214 * Makefile.in (LIB_EACCESS): New macro.
3216 * callproc.c (init_callproc):
3217 * charset.c (init_charset):
3218 * fileio.c (check_existing, check_executable, check_writable)
3220 * lread.c (openp, load_path_check):
3221 * process.c (allocate_pty):
3223 Use effective UID when checking permissions, not real UID.
3224 * callproc.c (init_callproc):
3225 * charset.c (init_charset):
3226 * lread.c (load_path_check, init_lread):
3227 Test whether directories are accessible, not merely whether they exist.
3228 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3229 * fileio.c (check_existing, check_executable, check_writable)
3231 Use symbolic names instead of integers for the flags, as they're
3233 (check_writable): New arg AMODE. All uses changed.
3234 Set errno on failure.
3235 (Ffile_readable_p): Use faccessat, not stat + open + close.
3236 (Ffile_writable_p): No need to call check_existing + check_writable.
3237 Just call check_writable and then look at errno. This saves a syscall.
3238 dir should never be nil; replace an unnecessary runtime check
3239 with an eassert. When checking the parent directory of a nonexistent
3240 file, check that the directory is searchable as well as writable, as
3241 we can't create files in unsearchable directories.
3242 (file_directory_p): New function, which uses 'stat' on most platforms
3243 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3244 (Ffile_directory_p, Fset_file_times): Use it.
3245 (file_accessible_directory_p): New function, which uses a single
3246 syscall for efficiency.
3247 (Ffile_accessible_directory_p): Use it.
3248 * xrdb.c (file_p): Use file_directory_p.
3249 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3250 * lread.c (openp): When opening a file, use fstat rather than
3251 stat, as that avoids a permissions race. When not opening a file,
3252 use file_directory_p rather than stat.
3253 (dir_warning): First arg is now a usage string, not a format.
3254 Use errno. All uses changed.
3255 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3256 that merely introduced a race.
3257 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3258 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3259 and similarly for the other O_* flags.
3260 * w32.c (sys_faccessat): Rename from sys_access and switch to
3261 faccessat's API. All uses changed.
3262 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3263 (magic_db): Rename from magic_file_p.
3264 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3265 char *, so that we don't have to test for file existence
3266 separately from opening the file for reading. This removes a race
3267 fixes a permission-checking problem, and simplifies the code.
3269 (file_p): Remove; no longer needed.
3271 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3273 Omit glyphs initialization at startup.

3285 frame's decode_mode_spec_buffer. This avoids crashes with very
3286 large values of FIELD_WIDTH argument to decode_mode_spec.
3289 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3291 Fix a race with verify-visited-file-modtime (Bug#12863).
3292 Since at least 1991 Emacs has ignored an mtime difference of no
3293 more than one second, but my guess is that this was to work around
3294 file system bugs that were fixed long ago. Since the race is
3295 causing problems now, let's remove that code.
3296 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3297 whose time stamp is off by no more than a second. Insist that the
3298 file time stamps match exactly.

3321 (x_window_to_menu_bar): Likewise.
3322 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3324 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3326 * data.c (Qdefalias_fset_function): Now static.
3328 Another tweak to vectorlike_header change.

3330 Remove, and replace all uses with ...
3331 (next_in_free_list, set_next_in_free_list):
3332 New functions, which respect C's aliasing rules better.
3334 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3336 * window.c (list4i): Rename from 'quad'. All uses changed.
3337 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3339 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3341 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3342 warning about mixing declarations and code in ISO C90.
3344 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3346 * window.c (Fsplit_window_internal): Set combination limit of
3347 new parent window to t iff Vwindow_combination_limit is t;
3348 fixing a regression introduced with the change from 2012-09-22.
3349 (Fset_window_combination_limit): Fix doc-string.
3351 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3353 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3354 amount when the scroll margins are too large. When scrolling
3355 backwards in the buffer, give up if cannot reach point or the
3356 scroll margin within a reasonable number of screen lines.
3357 Fixes point position in window under scroll-up/down-aggressively when
3358 point is positioned many lines beyond the window top/bottom.
3361 * ralloc.c (relinquish): If real_morecore fails to return memory
3362 to the system, don't crash; instead, leave the last heap
3363 unchanged and return. (Bug#12774)

3372 (Finteractive_form): Simplify.
3373 (Fquo): Don't insist on having at least 2 arguments.
3374 (Qdefalias_fset_function): New var.
3376 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>

3388 (SCROLL_BAR_VEC_SIZE): Remove.
3389 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3391 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3393 Tweak last vectorlike_header change.
3394 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3395 vectorlike object on the free list. This is introduced to avoid
3396 some (but not all) pointer casting and aliasing problems, see
3397 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3398 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

3409 * doc.c (Fdocumentation): Handle new property
3410 dynamic-docstring-function to replace the old ad-advice-info.
3412 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3414 * fns.c (Qeql, hashtest_eq): Now static.
3416 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>

3439 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3441 * image.c (xpm_make_color_table_h): Fix compiler error because
3442 make_hash_table changed.

3446 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3448 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3450 Use ad-hoc comparison function for the profiler's hash-tables.
3451 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3452 (make_log): Use them.
3453 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3454 call Fequal any more.

3464 (hash_lookup, hash_remove_from_table): Move assertion checking of
3465 hashfn result here. Check hash-equality before calling cmpfn.

3516 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3517 * buffer.h (struct buffer): Add next member.

3530 * keyboard.c (event_to_kboard): Do not dereference
3531 frame_or_window field of SELECTION_REQUEST_EVENT
3532 and SELECTION_CLEAR_EVENT events (Bug#12814).
3533 * xterm.h (struct selection_input_event): Adjust comment.
3535 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3537 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3538 such as Scroll Lock, if the respective keys are treated as
3539 function keys, not as modifiers. This avoids destroying non-ASCII
3540 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3542 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3544 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3546 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3548 Restore some duplicate definitions (Bug#12814).
3549 This undoes part of the 2012-11-03 changes. Some people build
3550 with plain -g rather than with -g3, and they need the duplicate
3551 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3552 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3553 Define as macros, as well as as enums or as constants.
3555 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3557 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3558 to keypad keys (Bug#12816).
3560 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3562 Minor adjustments of recently-changed frame functions.
3563 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3564 known to be a frame (we're in the FRAMEP branch).
3565 * lisp.h (Qframep): Remove decl. frame.h declares this.
3566 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3567 since they're meant for Lisp fixnum values.
3569 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3571 * window.c (Fwindow_combination_limit): Revert to the only
3572 required argument and adjust docstring as suggested in
3573 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3574 by Martin Rudalics <rudalics@gmx.at>.
3576 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>

3617 (Fwindow_line_height): Use it.
3618 (Fwindow_fringes): Use list3.
3619 (Fwindow_scroll_bars): Use list4.
3620 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3621 (Fwindow_combination_limit): Allow zero number of arguments.
3623 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3625 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3627 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3628 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3629 file descriptor 2 for standard error. (Bug#12805)
3631 2012-11-05 Chong Yidong <cyd@gnu.org>
3633 * process.c (wait_reading_process_output): Revert previous change.
3635 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3637 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3638 This removes code that has been obsolete since around 1990.
3639 * callproc.c (Fcall_process):
3641 * process.c (create_process):
3642 * term.c (dissociate_if_controlling_tty):
3643 Assume setsid exists.
3644 * callproc.c (child_setup): Assume setpgid exists and behaves as
3645 per POSIX.1-1988 or later.
3646 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3647 * emacs.c (shut_down_emacs):
3648 * sysdep.c (sys_suspend, init_foreground_group):
3649 Assume getpgrp behaves as per POSIX.1-1998 or later.
3650 * msdos.c (setpgrp): Remove.
3651 (tcgetpgrp, setpgid, setsid): New functions.
3652 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.

3660 Do not assume that __fpending's result fits in int.
3662 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3664 Remove EMACS_OUTQSIZE+sleep hack.
3665 * dispnew.c (update_frame_1): Remove hack for terminals slower
3666 than 2400 bps, which throttled Emacs by having it sleep.
3667 This code hasn't worked since at least 2007, when the multi-tty stuff
3668 was added, and anyway those old terminals are long dead.
3669 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3670 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3672 Fix data-loss with --version (Bug#9574).
3673 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3674 as we can't assume that emacs_strerror is initialized, and strerror
3675 is good enough here.
3676 (main): Invoke atexit earlier, to catch earlier instances of
3677 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3679 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3681 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).

3684 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3686 Fix data-loss with --batch (Bug#9574).
3687 * emacs.c: Include <close-stream.h>.
3688 (close_output_streams): New function.
3689 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3690 and handles errors appropriately.
3691 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3694 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3695 The symptom is a diagnostic "GLib-WARNING **: In call to
3696 g_spawn_sync(), exit status of a child process was requested but
3697 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3698 waitpid(), so exit status can't be returned." The diagnostic
3699 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3700 The real bug is a race condition between Emacs and glib: Emacs
3701 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3702 so that glib can't find it. Work around the bug by invoking
3703 waitpid only on subprocesses that Emacs itself creates.
3704 * process.c (create_process, record_child_status_change):
3705 Don't use special value -1 in pid field, as the caller now must
3706 know the pid rather than having the callee infer it.
3707 The inference was sometimes incorrect anyway, due to another race.
3708 (create_process): Set new 'alive' member if child is created.
3709 (process_status_retrieved): New function.
3710 (record_child_status_change): Use it.
3711 Accept negative 1st argument, which means to wait for the
3712 processes that Emacs already knows about. Move special-case code
3713 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3714 processes that have already been waited for, by testing and
3715 clearing new 'alive' member.
3716 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3717 now does this internally.
3718 (handle_child_signal): Let record_child_status_change do all
3719 the work, since we do not want to reap all exited child processes,
3720 only the child processes that Emacs itself created.
3721 * process.h (Lisp_Process): New boolean member 'alive'.
3723 Omit duplicate definitions no longer needed with gcc -g3.
3724 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3725 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3726 Define only as macros. There's no longer any need to also define
3727 these symbols as enums or as constants, since we now assume
3728 gcc -g3 when debugging.
3730 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3732 * lisp.mk: Adjust comments to the fact that term/internal is now
3733 loaded from loadup.el.
3735 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3736 (msdos_fatal_signal): New function.
3737 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3740 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3741 for GCC versions before 4.
3742 (emacs_raise): Define to call msdos_fatal_signal.
3744 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3745 iterator when starting in the middle of a display or overlay
3748 2012-11-03 Chong Yidong <cyd@gnu.org>
3750 * process.c (wait_reading_process_output): Clean up the last
3753 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3755 * process.c (wait_reading_process_output): Avoid a race condition
3756 with SIGIO delivery (Bug#11536).
3758 2012-11-03 Chong Yidong <cyd@gnu.org>
3760 * buffer.c (cursor_type): Untabify docstring.
3762 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3764 * frame.h (struct frame): Drop can_have_scroll_bars member
3765 which is meaningless for a long time. Adjust comments.
3766 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3767 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.

3771 * window.c (decode_next_window_args): Update window arg after
3772 calling decode_live_window and so fix crash reported at
3773 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3774 by Juanma Barranquero <lekktu@gmail.com>.
3775 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3776 * font.c (Ffont_at): Likewise.
3778 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>

3789 (BACKTRACE_LIMIT_MAX): New macro.
3790 (w32_backtrace): New function.
3791 (emacs_abort): Use w32_backtrace when the user chooses not to
3792 attach a debugger. Update the text of the abort dialog.
3794 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3796 Window-related stuff cleanup here and there.
3797 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3798 Use decode_any_window.
3799 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3800 * xdisp.c (Fformat_mode_line): Likewise.
3801 * font.c (Ffont_at): Use decode_live_window.

3804 (decode_any_window): Remove static.
3805 * window.h (decode_any_window): Add prototype.
3806 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3807 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3810 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3812 Remove pad from struct input_event.
3813 * termhooks.h (struct input_event): Remove padding field.
3815 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3816 member is never cons for a long time. Adjust comment.
3817 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3818 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3819 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3820 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3822 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3824 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3826 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3828 Fix crash when using Emacs as commit editor for git (Bug#12697).
3829 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3830 and it is configured in conf_post.h.
3831 (Fcall_process): Don't invoke both setsid and setpgid; the former
3832 is enough, if it exists.
3833 * callproc.c (Fcall_process, child_setup):
3834 * process.c (create_process): Use setpgid.
3835 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3837 * dispnew.c (init_display): Initialize the foreground group
3838 if we are running a tty display.
3839 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
3840 * lisp.h (init_foreground_group): New decl.
3841 * sysdep.c (inherited_pgroup): New static var.
3842 (init_foreground_group, tcsetpgrp_without_stopping)
3843 (narrow_foreground_group, widen_foreground_group): New functions.
3844 (init_sys_modes): Narrow foreground group.
3845 (reset_sys_modes): Widen foreground group.
3847 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3849 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3851 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3853 * minibuf.c (read_minibuf): Restore current buffer since
3854 choose_minibuf_frame calling Fset_frame_selected_window may
3855 change it (Bug#12766).
3857 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
3859 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
3861 2012-10-30 Kenichi Handa <handa@gnu.org>
3863 * font.c (Ffont_at): If WINDOW is specified and it is not
3864 displaying the current buffer, signal an error.
3866 2012-10-29 Daniel Colascione <dancol@dancol.org>
3868 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3869 In preparation for fixing bug#12739, move these functions from
3872 * coding.h, coding.c: ... to here, and compile them only when
3873 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3874 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3876 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3878 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
3879 (timer_loop, getitimer, setitimer): Use it instead of
3880 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
3882 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
3885 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
3887 * nsterm.m (NO_APPDEFINED_DATA): New define.

3889 (last_appdefined_event): Remove.
3890 (ns_select): Initialize t from last_appdefined_event_data instead
3891 of [last_appdefined_event data1].
3892 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
3893 remove last_appdefined_event (Bug#12698).
3895 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3897 * frame.c (x_set_font): Catch internal error.
3899 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3901 Avoid overflow in w32 implementation of interval timers.
3902 When possible, for ITIMER_PROF count only times the main thread
3904 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3905 'volatile ULONGLONG' types. All the other data which was
3906 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3907 (GetThreadTimes_Proc): New typedef.
3908 (w32_get_timer_time): New function, returns a suitable time value
3910 (timer_loop): Enter critical section when accessing ULONGLONG
3911 values of the itimer_data struct, as these accesses are no longer
3912 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3913 Remove unused variable.
3914 (init_timers): Initialize s_pfn_Get_Thread_Times.
3915 (start_timer_thread): Don't assign itimer->caller_thread here.
3916 (getitimer): Assign itimer->caller_thread here.
3917 (setitimer): Always call getitimer to get the value of ticks_now.
3918 (sys_spawnve): Avoid compiler warning about format mismatch.

3922 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3923 mouse movement events if the menu bar is active. This avoids
3924 producing a busy "hour-glass" cursor by Windows if the mouse
3925 pointer is positioned over a tooltip shown for some menu item.
3927 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3929 Don't assume process IDs fit in int.
3930 * emacs.c (shut_down_emacs) [!DOS_NT]:
3931 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3932 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3933 Use pid_t, not int, to store process IDs, as 'int'
3934 is not wide enough on a few platforms (e.g., AIX and IRIX).
3936 2012-10-23 Kenichi Handa <handa@gnu.org>
3938 The following change is to make face-font-rescale-alist work
3939 correctly for non-ASCII fonts.
3941 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
3942 (font_open_for_lface): Handle Vface_font_rescale_alist.
3944 2012-10-23 Chong Yidong <cyd@gnu.org>
3946 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
3948 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

3954 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
3957 2012-10-21 Glenn Morris <rgm@gnu.org>
3959 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3961 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
3963 Port to OpenBSD 5.1.
3964 * frame.c (Fmouse_position, Fmouse_pixel_position):
3965 * xdisp.c (produce_stretch_glyph):
3966 Declare local vars only when they're needed.
3967 This is clearer and avoids a warning on OpenBSD about unused vars.
3968 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
3969 This is safer, and avoids OpenBSD warnings about unused vars.
3970 * keyboard.c (record_menu_key): Remove unnecessary decl.
3971 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3972 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3973 as our definition clashes with OpenBSD's.
3974 * xfaces.c (load_face_colors, check_lface_attrs)
3975 (get_lface_attributes_no_remap, get_lface_attributes)
3976 (lface_fully_specified_p, x_supports_face_attributes_p)
3977 (tty_supports_face_attributes_p, face_fontset, realize_face)
3978 (realize_x_face, realize_tty_face):
3979 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3980 merely Lisp_Object *. This is more informative and avoids
3981 a warning on OpenBSD about accessing beyond an object's size.
3983 2012-10-20 Chong Yidong <cyd@gnu.org>
3985 * lread.c (Fload): Doc fix (Bug#12592).
3987 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
3989 * font.c (Ffont_at): Fix previous change.
3991 2012-10-19 Eli Zaretskii <eliz@gnu.org>
3993 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
3994 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
3997 * alloc.c (NSTATICS): Decrease to 0x800.
3999 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

4007 FD_ISSET (Bug#12668).
4009 2012-10-18 Daniel Colascione <dancol@dancol.org>
4011 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4012 (staticpro): If we run out of staticpro slots, die with an
4013 informative error instead of just calling emacs_abort.
4015 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4017 Fix two flaws reported by Dmitry Antipov.
4018 * window.c (Ftemp_output_buffer_show): Remove.

4040 (sys_link): Add prototypes.
4042 * w32.c: Include w32select.h.
4043 (sys_access, e_malloc, sys_select): Add prototypes.

4060 Lisp_Object values. (Bug#12661)
4062 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
4063 to Lisp_Object. (Bug#12661)

4135 2012-10-13 Paul Eggert <eggert@cs.ucla.edu>
4137 Fix some stat-related races.
4138 * fileio.c (Fwrite_region): Avoid race condition if a file is
4139 removed or renamed by some other process immediately after Emacs
4140 writes it but before Emacs stats it. Do not assume that stat (or
4142 * image.c (slurp_file): Resolve the file name with fopen + fstat
4143 rather than stat + fopen.

4171 * fileio.c (check_existing): New function.
4172 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
4173 instead of calling 'stat', when what's needed is to check whether
4174 a file exists. This avoids expensive system calls on MS-Windows.
4177 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
4179 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
4180 determine whether a file exists and is not a directory.

4184 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
4186 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

4216 Use bool for booleans.
4217 * lread.c (safe_to_load_version): Rename from safe_to_load_p,

4270 * process.c (wait_reading_process_output):
4271 Use unsigned for counter where wraparound-on-overflow is desired,
4272 since unsigned is guaranteed to have that behavior and signed is not.
4273 (read_char): Use ptrdiff_t for string length.
4274 (get_input_pending): Remove first argument, since it was always
4275 the same pointer-to-int (now pointer-to-boolean) &input_pending,
4276 and behave as if it had that value. Return new value of
4277 input_pending. All callers changed.
4278 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4279 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
4281 * keymap.c (push_key_description): Omit last arg, which was always 1.
4282 All callers changed.
4284 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
4286 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

4302 Don't include termopts.h.
4304 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
4306 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
4308 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4310 * commands.h (immediate_quit): Remove duplicate decl.
4312 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
4314 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

4317 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
4319 2012-10-09 Eli Zaretskii <eliz@gnu.org>
4321 * w32fns.c (w32_last_error): Change the return value to DWORD, to
4322 match what GetLastError returns. Explain why the function is
4325 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4326 'is_tooltip_frame', to avoid confusion with its global namesake.
4328 2012-10-08 Daniel Colascione <dancol@dancol.org>
4330 * xdisp.c (start_hourglass): Call w32_note_current_window when
4331 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4332 build that caused Emacs to display the hourglass cursor forever.
4334 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4335 which is broken under remote desktop, calculate the number of
4336 colors available for a display based on the display's number of
4337 planes and number of bits per pixel per plane. (bug#10397).
4339 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4341 * nsfont.m (Vfonts_in_cache): New variable.
4342 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4343 are used. Add cached fonts to Vfonts_in_cache.
4344 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4346 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4348 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4350 (FONT_H): Define after FRAME_H.
4351 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4352 Update dependencies.
4354 * w32term.c: Remove leftover declaration of keyboard_codepage.
4356 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4358 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4359 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4360 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4361 (GLOBAL_SOURCES): Add cygw32.c.
4362 ($(BLD)/unexw32.$(O)):
4364 ($(BLD)/w32console.$(O)):
4365 ($(BLD)/w32fns.$(O)):
4366 ($(BLD)/w32heap.$(O)):
4367 ($(BLD)/w32menu.$(O)):
4368 ($(BLD)/w32proc.$(O)): Add w32common.h.
4370 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4372 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4374 2012-10-08 Daniel Colascione <dancol@dancol.org>
4376 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4377 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4378 accidental message numbering hole. Change other messages to
4381 * w32select.h (HAVE_W32SELECT): Remove.
4383 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4384 w32common.h instead of w32heap.h.
4386 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4387 (get_allocation_unit, get_processor_type, get_w32_major_version)
4388 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4389 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4390 (OS_NT, os_subtype, cache_system_info): Move declarations to
4393 * w32heap.c: Include w32common.h.
4394 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4395 (w32_minor_version, w32_build_number, w32_subtype):
4396 Remove duplicate definitions.
4398 * w32fns.c: Include w32common.h; include w32heap.h only in
4401 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4402 Use `report_file_error' instead of `error' in order to better
4403 inform users of what went wrong. Increase NTGUI_UNICODE file
4404 dialog box file name length to 32k, the maximum allowed by the NT
4407 * w32common.h: New file.
4408 (ROUND_UP, ROUND_DOWN, get_page_size)
4409 (get_allocation_unit, get_processor_type, get_w32_major_version)
4410 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4411 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4412 (OS_NT, os_subtype, cache_system_info): Move here.
4414 * unexw32.c, unexcw.c: Include w32common.h.
4416 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4417 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4418 to call syms_of_w32select.
4420 * cygw32.h: Remove obsolete EXFUN declarations.
4422 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4424 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4425 of w32inevt.o from SOME_MACHINE_OBJECTS.
4427 2012-10-08 Daniel Colascione <dancol@dancol.org>
4429 * image.c: Permanent fix for JPEG compilation issue --- limit
4430 jpeglib `boolean' redefinition to Cygwin builds.
4432 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4434 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4436 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4439 2012-10-08 Daniel Colascione <dancol@dancol.org>
4441 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4442 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4443 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4444 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4445 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4446 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4447 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4448 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4449 now a supported configuration.
4451 * Makefile.in: consolidate image variables into LIBIMAGE; add
4452 W32_OBJ and W32_LIBS. Compile new files.
4455 (_DebPrint) declare tracing facility for W32 debugging. We need
4456 to unify tracing later.
4458 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4459 unconditional use of W32 Unicode functions. Cygwin runs only on
4460 100% Unicode operating systems.
4462 * cygw32.c: New file. Define Cygwin-specific facilities.
4463 (Fcygwin_convert_path_to_windows)
4464 (Fcygwin_convert_path_from_windows): New user functions for
4465 accessing Cygwin path-munging routines.
4467 * cygw32.h: New file.
4468 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4469 UTF-16LE strings temporarily inside non-Lisp-visible string
4472 (w32_strerror): Just what it says on the tin.
4474 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4475 also run for Cygwin; both systems have the same problem with using
4476 GUI facilities in a forked child. Also call syms_of_cygw32,
4477 syms_of_w32select in correct places.
4479 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4480 needs fork-then-exec for daemon launching.
4482 * font.h: Include frame.h.
4484 * image.c: Use the image library cache machinery only when we're
4485 compiling for native WINDOWSNT; Cygwin can use shared libraries
4486 like any other Unixlike system.
4488 * keyboard.c: Clarify a comment regarding the input loop.
4490 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4491 functions directly instead of trying to detect at runtime that our
4492 host operating system supports them. We make this change for two
4493 reasons: Cygwin lacks support for the multibyte character
4494 conversion functions used by the legacy menu code, and Cygwin
4495 never needs to rely on non-Unicode APIs.
4497 * unexw32.c (hinst): Declare extern.
4499 * w32.c: Change header order;
4500 (w32_strerror): Move to w32fns.c because we need it for
4501 non-WINDOWSNT builds.
4503 * w32.h: Add #error macro to make sure we don't include w32.h for
4504 Cygwin builds. Remove w32select declarations.
4506 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4507 w32fns.c. w32console.c is WINDOWSNT-only.
4509 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4510 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4512 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4513 (w32_major_version, w32_minor_version, w32_build_number)
4514 (os_subtype, sound_type): Define here
4515 (w32_defined_color): Make color parameter const for consistency
4516 with other _defined_color functions.
4517 (w32_createwindow): Unconditionally call w32_init_class instead of
4518 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4519 through the code is complex and unnecessary because class
4520 registration is practically free.
4521 (w32_name_of_message): New EMACSDEBUG-only function.
4522 (Fset_message_beep): Move here
4523 (Fx_open_connection): Require that the display name for Windows be
4524 "w32" for consistency, emacsclient disambiguation, and maybe, one
4525 day, multi-window-system support.
4526 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4527 Cygwin files for W32 GUI facilities, since these clearly don't
4528 expect Cygwin names.
4529 (_DebPrint): Define.
4530 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4531 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4532 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4533 (w32_last_error): Remove.
4535 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4537 * w32heap.c (syspage_mask): Declare here.
4538 (cache_system_info): Remove.
4540 * w32inevt.c (faked_key): Define globally, not statically.
4541 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4542 (w32_console_toggle_lock_key): Move to w32fns.c.
4544 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4546 * w32proc.c (_DebPrint): Move to w32fns.c.
4547 * w32select.c: Include string.h, stdio.h for Cygwin.
4548 * w32select.h: New File.
4550 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4552 (w32_message_fd): New variable. Under Cygwin, holds the file
4553 descriptor the system used to tell us about pending thread
4556 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4557 that prevented compilation under non-WINDOWSNT systems.
4559 (w32_initialize): Open /dev/windows and assign it to
4560 w32_message_fd. Provide w32 feature.
4562 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4563 (WM_EMACS_INPUT_READY): add.
4564 (prepend_msg, w32_message_fd): Declare globally.
4567 (keyboard_handle): Use only when WINDOWSNT.
4568 (notify_msg_ready): New function. Posts a message to the main
4569 thread's message queue under CYGWIN, which wakes up the main
4570 thread from select(2) by making the /dev/windows file descriptor
4571 ready. Under WINDOWSNT, it sets an event the same way the old
4574 (post, prepend_msg): Actually call notify_msg_ready instead of
4575 setting the input event directly.
4577 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4579 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4580 but it still has blocs in it, don't return it to the system,
4581 instead of aborting. (Bug#12402)
4583 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4585 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4587 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4588 MAC_OS_X_VERSION_10_6.
4589 (syms_of_nsterm): Remove comment about Panther and above for

4593 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4595 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4596 MAC_OS_X_VERSION_10_4.
4598 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4599 MAC_OS_X_VERSION_10_2.
4601 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4603 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4604 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4606 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4607 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4608 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4609 Remove ns_in_resize check.
4610 (ns_clear_frame_area): Remove resize handle code.
4612 * nsfns.m (ns_in_resize): Remove.
4613 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4614 Remove ns_in_resize check.
4616 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4618 Improve sys_siglist detection.
4619 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4620 defined as a macro, as is done in Solaris.
4621 (sys_siglist_entries): New macro.
4622 (save_strsignal): Use it.
4623 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4624 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4626 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4628 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4629 fullscreen/Fullscreen.
4631 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4632 tobar_height is new.
4634 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4635 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4636 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4637 (windowDidResize:): Check for correct window if old style fullscreen.
4638 Capitalize word in comment. Remove incorrect comment.
4639 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4640 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4641 error in drawing background.
4642 (toggleFullScreen:): Remove comment. Rearrange calls.

4651 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4653 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4655 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4656 that time stamps of directories could also be changed.
4657 Don't request the too broad GENERIC_WRITE, only the more restrictive
4658 FILE_WRITE_ATTRIBUTES access rights.
4660 * fileio.c (Fset_file_times): Special-case ignoring errors for
4661 directories only on MSDOS, not on MS-Windows.
4663 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)

4674 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4675 to avoid similar races.
4676 * keyboard.c (pending_signals): Now bool, not int.
4678 Port timers to OpenBSD, plus check for timer failures.
4679 OpenBSD problem reported by Han Boetes.
4680 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4682 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4683 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4684 like OpenBSD, which has timer_settime but does not declare it.
4685 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4686 whether to use itimerspec-related primitives. All uses of
4687 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4689 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4691 * profiler.c (handle_profiler_signal): Fix a malloc race
4692 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4694 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4696 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4698 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4700 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4701 consistent with the change in return value of 'safe_strsignal'.
4703 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>

4713 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4714 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4715 Now 'static', not 'static inline'.
4717 Count overruns when profiling; change units to ns.
4718 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4719 Give extra weight to samples after overruns, to attempt to count
4720 the time more accurately.
4721 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4722 the underlying primitives nominally do ns.
4723 (Fprofiler_cpu_start): Document the change. Mention that
4724 the sampling intervals are only approximate.
4726 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4728 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4730 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4731 case for the special 0 coding-system.
4733 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4734 (Fmake_overlay): Remove redundant tests.
4735 (fix_start_end_in_overlays): Remove redundant recentering.
4737 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4739 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4740 Update dependencies.
4742 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4744 Fix a malloc race condition involving strsignal.
4745 A signal can arrive in the middle of a malloc, and Emacs's signal
4746 handler can invoke strsignal, which can invoke malloc, which is
4747 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4748 Fix it by altering the signal handler so that it does not invoke
4750 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4751 * process.c (status_message): Use const pointer, in case strsignal
4752 is #defined to safe_strsignal.
4753 * sysdep.c (sys_siglist, init_signals): Always define and
4754 initialize a substitute sys_siglist if the system does not define
4755 one, even if HAVE_STRSIGNAL.
4756 (safe_strsignal): Rename from strsignal. Always define,
4757 using sys_siglist. Return a const pointer.
4758 * syssignal.h (safe_strsignal): New decl.
4759 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4761 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4763 * w32proc.c (timer_loop): Fix code that waits for timer
4764 expiration, to avoid high CPU usage.
4766 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4768 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4769 (sweep_weak_table): Remove redundant prototypes.
4771 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4773 * emacs.c: Move the inclusion of TERM_HEADER after including
4774 windows.h on WINDOWSNT. This avoids compilation problems with
4777 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4779 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4780 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4781 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4782 as the previous version used 'void *'.
4784 * ralloc.c (ROUNDUP): Fix last change.
4785 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4788 * w32proc.c <disable_itimers>: New static flag.
4789 (init_timers): Initialize it to zero, after creating the critical
4790 sections used by the timer threads.
4791 (term_timers): Set to 1 before deleting the critical sections.
4792 (getitimer, setitimer): If disable_itimers is non-zero, return an
4793 error indication without doing anything. Reported by Fabrice
4794 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4795 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4797 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4800 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4801 term_ntproc after all the other bookkeeping, to get timers working
4802 as long as possible.
4804 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4806 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4807 Suggested by Juri Linkov in
4808 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4810 Prefer plain 'static' to 'static inline' (Bug#12541).
4811 With static functions, modern compilers inline pretty well by
4812 themselves; advice from programmers often hurts as much as it helps.
4813 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4814 this change shrinks the text size of the Emacs executable by 1.1%
4815 without affecting CPU significantly in my benchmark.

5089 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
5091 2012-09-30 Eli Zaretskii <eliz@gnu.org>
5093 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
5094 HAVE_TIMER_SETTIME is defined.
5096 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5098 Profiler improvements: more-accurate timers, overflow checks.
5099 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
5100 signal.h, setjmp.h. Include systime.h instead.
5101 (saturated_add): New function.
5102 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
5103 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
5104 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
5106 (enum profiler_cpu_running): New enum.
5107 (profiler_cpu_running): Now of that enum type, not bool.
5108 All uses changed to store the new value.
5109 (handle_profiler_signal): Rename from sigprof_handler_1,
5110 for consistency with other handlers. Do not check whether
5111 cpu_log is a hash-table if garbage collecting, since it
5112 doesn't matter in that case.
5113 (deliver_profiler_signal): Rename from sigprof_handler,
5114 for consistency with other handlers.
5115 (setup_cpu_timer): New function, with much of what used to be in
5116 Fprofiler_cpu_start. Check for out-of-range argument.
5117 Prefer timer_settime if available, and prefer
5118 thread cputime clocks, then process cputime clocks, then
5119 monotonic clocks, to the old realtime clock. Use make_timeval
5120 to round more-correctly when falling back to setitimer.
5121 (Fprofiler_cpu_start): Use it.
5122 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5123 Don't assume that passing NULL as the 2nd argument of setitimer
5124 is the same as passing a pointer to all-zero storage.
5125 Ignore SIGPROF afterwards.
5126 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5127 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5128 non-fatal signal handlers. Ignore SIGPROF on startup.
5129 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5130 in profiler.c, since sysdep.c now uses it.
5132 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

5147 (Fbacktrace_frame): Adjust accordingly.
5149 2012-09-28 Glenn Morris <rgm@gnu.org>
5151 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)

5184 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
5186 * character.h (MAYBE_UNIFY_CHAR): Remove.
5187 * charset.c, charset.h (maybe_unify_char): Now static.
5188 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5189 Since this stuff is now private to charset.c, there's no need for
5190 a public macro and no need to inline by hand.

5223 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
5225 Prefer POSIX timers if available.
5226 They avoid a race if the timer is too close to the current time.
5227 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
5228 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
5229 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
5231 2012-09-25 Eli Zaretskii <eliz@gnu.org>

5234 CHAR_STRING_ADVANCE.
5235 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
5236 STRING_CHAR_ADVANCE.

5252 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
5254 * w32.h (Vlibrary_cache): Do not declare.
5256 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5258 * w32proc.c (sys_signal): Handle all signals defined by the
5259 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5260 handlers for signals supported by Windows. Don't override
5261 term_ntproc as the handler for SIGABRT.
5262 (sigaction): Rewrite to call sys_signal instead of duplicating its
5264 (sys_kill): Improve commentary.
5266 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5267 consistency with a signature of a signal handler. All callers
5269 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5270 install term_ntproc as a signal handler for SIGABRT, as that
5271 should be done by the dumped Emacs.
5273 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5275 * w32select.c (term_w32select): Protect against repeated
5276 invocation by setting clipboard_owner to NULL after calling
5279 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5280 and term_ntproc to their modified signatures.
5282 * character.c (char_string, string_char): Remove calls to
5283 MAYBE_UNIFY_CHAR. See the discussion starting at

5291 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5293 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5294 when encountering an unknown bytecode.
5296 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5298 image.c, indent.c: Use bool for booleans.

5301 * image.c: Omit unnecessary static decls.
5302 (x_create_bitmap_mask, x_build_heuristic_mask):

5340 Move pid_t related decls out of lisp.h.
5341 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5342 (interruptible_wait_for_termination):
5343 Move these decls from lisp.h to syswait.h, since they use pid_t.
5344 Needed on FreeBSD; see Herbert J. Skuhra in
5345 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.

5394 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5395 fatal_error_backtrace.
5397 * w32proc.c (sys_kill): Undo last change: don't do anything when
5398 invoked to deliver SIGABRT to our own process. This is now
5399 handled by emacs_raise.
5401 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5403 * w32term.c (w32_read_socket): Remove leftover reference to
5404 interrupt_input_pending.
5406 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5408 Do not use SA_NODEFER.
5409 Problem reported by Dani Moncayo in
5410 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5412 * sysdep.c (emacs_abort): Do not reset signal handler.
5413 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5414 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5415 wanted even on POSIXish hosts, and it doesn't work on Windows.
5417 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5419 * xterm.c (x_term_init): Call fixup_locale before and after calling
5420 gtk_init (Bug#12392).
5422 2012-09-23 Chong Yidong <cyd@gnu.org>
5424 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5425 Vdynamic_library_alist.
5427 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5428 (Fgnutls_available_p): Caller changed.
5430 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5431 (Flibxml_parse_xml_region): Likewise.
5433 * dispextern.h (struct image_type): Remove arg from init function.
5435 * image.c (Finit_image_library, lookup_image_type)
5436 (define_image_type): Remove now-unneeded second arg.
5437 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5438 (init_tiff_functions, init_gif_functions, init_svg_functions):
5439 Arglist and w32_delayed_load calling convention changed.
5440 (gs_type): Remove init_gs_functions; there is no such function.
5441 (valid_image_p, make_image): Fix caller to lookup_image_type.
5443 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5445 Simplify and avoid signal-handling races (Bug#12471).
5447 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5448 Avoid recursive loop if there's a fatal error in the function itself.
5449 * atimer.c (pending_atimers):
5450 * blockinput.h: Don't include "atimer.h"; no longer needed.
5451 (interrupt_input_pending): Remove. All uses removed.
5452 pending_signals now counts both atimers and ordinary interrupts.
5453 This is less racy than having three separate pending-signal flags.
5454 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5456 Rename from their upper-case counterparts BLOCK_INPUT,
5457 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5458 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5459 This makes it easier to access volatile variables more accurately.
5460 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5461 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5462 that's more reliable if the code is buggy and sets
5463 interrupt_input_blocked to a negative value. All uses changed.
5464 * atimer.c (deliver_alarm_signal):
5465 Remove. No need to deliver this to the parent; any thread can
5466 handle this signal now. All uses replaced by underlying handler.
5467 * atimer.c (turn_on_atimers):
5468 * dispnew.c (handle_window_change_signal):
5469 * emacs.c (handle_danger_signal):
5470 * keyboard.c (kbd_buffer_get_event):
5471 Don't reestablish signal handler; not needed with sigaction.
5472 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5474 Rework to avoid unnecessary accesses to volatile variables.
5475 (UNBLOCK_INPUT_TO): Now a function.
5476 (totally_unblock_input, unblock_input): New decls.
5477 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5478 (init_data): Remove. Necessary stuff now done in init_signal.
5479 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5480 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5481 (fatal_error_code): Remove; no longer needed.
5482 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5483 it doesn't always backtrace. All uses changed. No need to reset
5484 signal to default, since sigaction and/or die does that for us now.
5485 Use emacs_raise (FOO), not kill (getpid (), FOO).
5486 (main): Check more-accurately whether we're dumping.
5487 Move fatal-error setup to sysdep.c
5488 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5489 * gtkutil.c (xg_get_file_name, xg_get_font):
5490 Remove no-longer-needed signal-mask manipulation.
5491 * keyboard.c, process.c (POLL_FOR_INPUT):
5492 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5493 * keyboard.c (read_avail_input): Remove.
5494 All uses replaced by gobble_input.
5495 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5496 (kbd_buffer_store_event_hold, gobble_input):
5497 (record_asynch_buffer_change) [USABLE_SIGIO]:
5498 (store_user_signal_events):
5499 No need to mess with signal mask.
5500 (gobble_input): If blocking input and there are terminals, simply
5501 set pending_signals to 1 and return. All hooks changed to not
5502 worry about whether input is blocked.
5503 (process_pending_signals): Clear pending_signals before processing
5504 them, in case a signal comes in while we're processing.
5505 By convention callers now test pending_signals before calling us.
5506 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5507 New functions, to support changes to blockinput.h.
5508 (handle_input_available_signal): Now extern.
5509 (reinvoke_input_signal): Remove. All uses replaced by
5511 (quit_count): Now volatile, since a signal handler uses it.
5512 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5513 All callers changed. Block SIGINT only if not already blocked.
5514 Clear sigmask reliably, even if Fsignal returns, which it can.
5515 Omit unnecessary accesses to volatile var.
5516 (quit_throw_to_read_char): No need to restore sigmask.
5517 * keyboard.c (gobble_input, handle_user_signal):
5518 * process.c (wait_reading_process_output):
5519 Call signal-handling code rather than killing ourselves.
5520 * lisp.h: Include <float.h>, for...
5521 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5522 (pending_signals): Now volatile.
5523 (syms_of_data): Now const if IEEE floating point.
5524 (handle_input_available_signal) [USABLE_SIGIO]:
5525 (terminate_due_to_signal, record_child_status_change): New decls.
5526 * process.c (create_process): Avoid disaster if memory is exhausted
5527 while we're processing a vfork, by tightening the critical section
5529 (send_process_frame, process_sent_to, handle_pipe_signal)
5530 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5532 (send_process): No need for setjmp/longjmp any more, since the
5533 SIGPIPE stuff is now gone. Instead, report an error if errno
5535 (record_child_status_change): Now extern. PID and W are now args.
5536 Return void, not bool. All callers changed.
5537 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5538 Remove. All uses removed. This bug should be fixed now in a
5540 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5541 and record the child status change directly. This avoids the
5542 need to futz with the signal mask.
5543 (process_fatal_action): Move here from emacs.c.
5544 (emacs_sigaction_flags): New function, containing
5545 much of what used to be in emacs_sigaction_init.
5546 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5547 caught by emacs, to make races less likely.
5548 (deliver_process_signal): Rename from handle_on_main_thread.
5550 (BACKTRACE_LIMIT_MAX): Now at top level.
5551 (thread_backtrace_buffer, threadback_backtrace_pointers):
5553 (deliver_thread_signal, deliver_fatal_thread_signal):
5554 New functions, for more-accurate delivery of thread-specific signals.
5555 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5556 (deliver_arith_signal): Handle in this thread, not
5557 in the main thread, since it's triggered by this thread.
5558 (maybe_fatal_sig): New function.
5559 (init_signals): New arg DUMPING so that we can be more accurate
5560 about whether we're dumping. Caller changed.
5561 Treat thread-specific signals differently from process-general signals.
5562 Block all signals while handling fatal error; that's safer.
5563 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5565 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5566 Ignore SIGPIPE unless batch.
5567 (emacs_backtrace): Output backtrace for the appropriate thread,
5568 which is not necessarily the main thread.
5569 * syssignal.h: Include <stdbool.h>.
5570 (emacs_raise): New macro.
5571 * xterm.c (x_connection_signal): Remove; no longer needed
5572 now that we use sigaction.
5573 (x_connection_closed): No need to mess with sigmask now.
5574 (x_initialize): No need to reset SIGPIPE handler here, since
5575 init_signals does this for us now.
5577 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5579 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5580 background rect may be larger (Bug#12245).
5582 2012-09-23 Chong Yidong <cyd@gnu.org>
5584 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5586 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5588 * .gdbinit: Just stop at fatal_error_backtrace.
5589 See Stefan Monnier's request in
5590 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5591 Remove no-longer-used query of system type.
5593 2012-09-22 Chong Yidong <cyd@gnu.org>
5595 * search.c (Freplace_match): Doc fix (Bug#12325).
5597 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5599 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5600 (Fline_end_position): Doc fix.
5602 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5604 2012-09-22 Chong Yidong <cyd@gnu.org>
5606 * dispextern.h (struct image_type): Add new slot, storing a type
5607 initialization function.
5609 * image.c (define_image_type): Call the image initializer function
5610 if it is defined. Arguments and return value changed.
5611 (valid_image_p, make_image): Callers changed.
5612 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5613 (gif_type, imagemagick_type, svg_type, gs_type):
5614 Add initialization functions.
5615 (Finit_image_library): Call lookup_image_type.
5616 (CHECK_LIB_AVAILABLE): Macro deleted.
5617 (lookup_image_type): Call define_image_type here, rather than via
5618 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5619 (syms_of_image): Move define_image_type calls for xbm_type and
5620 pbm_type to lookup_image_type.
5622 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5624 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5625 'idle_timers' from here ...
5626 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5627 lists, to avoid infloops when the timer does something stupid,
5628 like reinvoke itself with the same or smaller time-out.
5631 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5633 * window.c (Fsplit_window_internal): Handle only Qt value of
5634 Vwindow_combination_limit separately.
5635 (Qtemp_buffer_resize): New symbol.
5636 (Vwindow_combination_limit): New default value.
5639 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5641 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5642 the new overlay string. (Bug#10159)
5644 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5646 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5647 or that fprintf is async-signal-safe. POSIX doesn't require
5650 2012-09-22 Chong Yidong <cyd@gnu.org>
5652 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5655 2012-09-22 Kenichi Handa <handa@gnu.org>
5657 * composite.c (composition_reseat_it): Handle the case that a
5658 grapheme cluster is not covered by a single font (Bug#12352).
5660 2012-09-21 Chong Yidong <cyd@gnu.org>
5662 * image.c (define_image_type): Avoid adding duplicate types to
5663 image_types (Bug#12463). Suggested by Jörg Walter.
5665 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5667 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5668 (print_load_command_name): Add case LC_DATA_IN_CODE.
5669 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5671 2012-09-21 Glenn Morris <rgm@gnu.org>
5673 * eval.c (Frun_hook_with_args_until_success)
5674 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5676 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5678 * fileio.c (Ffile_selinux_context): Only call freecon when
5679 lgetfilecon succeeded.
5680 (Fset_file_selinux_context): Likewise. (Bug#12444)
5682 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5684 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5685 reordering, locate the cursor by calling set_cursor_from_row; if
5686 that fails, clear the desired glyph matrix before returning a
5687 failure indication to the caller. Fixes leaving garbled display
5688 when fast scrolling with a down-key. (Bug#12403)
5689 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5690 scrolling through multibyte text.
5692 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5694 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5695 calling mark_vectorlike since that's the one that marks the window.
5696 (mark_discard_killed_buffers): Mark the final cdr.
5697 * window.h (struct window): Move prev/next_buffers to the
5698 non-standard fields.
5699 * window.c (make_window): Initialize prev/next_buffers manually.
5701 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5703 Omit unused arg EXPECTED from socket hooks.
5704 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5705 * nsterm.m (ns_term_init):
5706 * termhooks.h (struct terminal.read_socket_hook):
5707 * w32inevt.c (w32_console_read_socket):
5708 * w32term.c (w32_read_socket):
5709 * xterm.c (XTread_socket):
5710 Omit unused arg EXPECTED. All callers changed.
5711 (store_user_signal_events): Return void, not int, since callers no
5712 longer care about the return value. All uses changed.
5714 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5716 * w32gui.h (XParseGeometry): Do not declare.
5718 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5720 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5721 Ignore 'expected'. See Eli Zaretskii in
5722 <http://bugs.gnu.org/12471#8> (last line).
5724 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5725 (XParseGeometry): Now static. Substitute extremal values for
5726 values that are out of range.
5728 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5730 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5732 * nsfns.m (XParseGeometry): Remove.
5733 (Fx_create_frame): Call x_set_offset to correctly interpret
5734 top_pos in geometry.
5736 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5737 (Fx_parse_geometry): If there is a space in string, call
5738 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5740 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5742 * search.c (scan_buffer): Use character positions in calls to
5743 region_cache_forward and region_cache_backward, not byte
5744 positions. (Bug#12196)
5746 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5747 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5749 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5750 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5751 emacs_blocked_malloc, now deleted.
5753 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5755 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5756 The workaround was for improving performance on Solaris 2.4, but
5757 is getting in the way now. Emacs will still work if someone is
5758 still running Solaris 2.4 in a museum somewhere; Sun dropped
5759 support for Solaris 2.4 in 2003.
5760 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5761 * process.c (create_process) [HAVE_WORKING_VFORK]:
5762 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5763 since Emacs no longer uses vfork on that platform.
5765 2012-09-17 Glenn Morris <rgm@gnu.org>
5767 * emacs.c: Use COPYRIGHT.
5769 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5771 Remove configure's --without-sync-input option (Bug#12450).
5772 When auditing signal-handling in preparation for cleaning it up,
5773 I found that SYNC_INPUT has race conditions and would be a real
5774 pain to fix. Since it's an undocumented and deprecated
5775 configure-time option, now seems like a good time to remove it.
5776 Also see <http://bugs.gnu.org/11080#16>.
5777 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5778 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5779 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5780 (malloc_hysteresis):
5781 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5782 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5783 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5784 (dont_register_blocks, bytes_used_when_reconsidered)
5785 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5786 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5787 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5788 Remove. All uses removed.
5789 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5790 implementation, one that depends on whether the new macro
5791 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5793 * atimer.c (run_timers, handle_alarm_signal):
5794 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5795 (handle_async_input, process_pending_signals)
5796 (handle_input_available_signal, init_keyboard):
5797 * nsterm.m (ns_read_socket):
5798 * process.c (wait_reading_process_output):
5799 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5800 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5802 * xterm.c (XTread_socket):
5804 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5805 * eval.c (handling_signal): Remove. All uses removed.
5806 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5807 All uses replaced with the SYNC_INPUT version.
5808 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5810 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5813 * font.c (Ffont_shape_gstring): Remove unused local.
5815 2012-09-16 Glenn Morris <rgm@gnu.org>
5817 * Makefile.in (clean): No longer run nextstep's clean.
5819 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5821 (ns-app): Move here from ns.mk, and simplify.
5822 (clean): Simplify nextstep entry.
5823 * ns.mk: Remove file.
5825 2012-09-17 Kenichi Handa <handa@gnu.org>
5827 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5828 not covert the last few charactes.
5830 2012-09-16 Kenichi Handa <handa@gnu.org>
5832 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5833 here, but just check the validity of glyphs in the glyph-string.
5835 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5837 * window.c (Fwindow_parameter, Fset_window_parameter):
5838 Accept any window as argument (Bug#12452).
5840 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5842 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5843 to ns_term_init to avoid memory leak.
5845 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5846 explicit retain/release.
5847 (ns_term_init): Only allow one display. Initialize outerpool and
5850 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5852 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5853 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5854 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5855 the Microsoft problem in a different way, by altering ../nt/config.nt.
5857 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5872 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5873 by lisp.h. This completes removal of setjmp.h inclusion
5874 erroneously announced in the previous commit. (Bug#12446)
5876 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5879 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5880 not defined as a macro. The latter happens on MS-Windows.
5883 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5885 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5886 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5887 Some instances of '#include <setjmp.h>' removed, if the
5888 only reason for the instance was because "lisp.h" was included.
5889 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5890 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5891 and _longjmp with the new symbols. Emacs already uses _setjmp if
5892 available, so this change affects only POSIXish hosts that have
5893 sigsetjmp but not _setjmp, such as some versions of Solaris and
5894 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5895 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5896 (png_load_body) [HAVE_PNG]:
5897 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5898 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5899 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5900 since PNG requires jmp_buf. This is the only exception to the
5901 general rule that we now use sys_setjmp and sys_longjmp.
5902 This exception is OK since this code does not change the signal
5903 mask or longjmp out of a signal handler.
5905 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5907 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5908 Include "syssignal.h", for 'main_thread'.
5910 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5912 Avoid out-of-range marker position (Bug#12426).
5913 * insdel.c (replace_range, replace_range_2):
5914 Adjust markers before overlays, as suggested by comments.
5915 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5916 Remove redundant check before calling offset_intervals.
5918 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5920 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5921 current buffer (Bug#12387).
5923 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5925 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5927 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5929 Use a more backwards-compatible timer format (Bug#12430).
5930 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5931 vector element, not from the 4th, since PSECS is now at the end.
5932 (Fcurrent_idle_time): Doc fix.
5934 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5936 Function to mark objects and remove killed buffers at once.
5937 * alloc.c (discard_killed_buffers): Rename to ...
5938 (mark_discard_killed buffers) ... new name. Add marking
5939 of remaining objects. Fix comment. Adjust users.
5940 (mark_object): Do not touch frame buffer lists here.
5941 * frame.c (delete_frame): Reset frame buffer lists here.
5943 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5945 Better workaround for GNOME bug when --enable-gcc-warnings.
5946 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5947 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5948 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5950 Simplify SIGIO usage (Bug#12408).
5951 The code that dealt with SIGIO was crufty and confusing, e.g., it
5952 played tricks like "#undef SIGIO" but these tricks were not used
5953 consistently. Simplify mostly by not #undeffing standard symbols,
5954 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5955 or not as we please) rather than "defined SIGIO" (standard symbol
5956 that we probably shouldn't #undef).
5957 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5958 Modules that need it can include it.
5959 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5960 * dispextern.h (ignore_sigio): New decl.
5961 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5962 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5963 * emacs.c (shut_down_emacs):
5964 * keyboard.c (kbd_buffer_store_event_hold):
5965 Use ignore_sigio rather than invoking 'signal' directly.
5966 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5968 (FIONREAD, SIGIO): Do not #undef.
5969 (tty_read_avail_input): Use #error rather than a syntax error.
5970 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5971 for I_PIPE, used by SETUP_SLAVE_PTY.
5972 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5973 * sysdep.c (croak): Remove; no longer needed. This bit of
5974 temporary code, with Fred N. Fish's comment that it's temporary,
5975 has been in Emacs since at least 1992!
5976 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5977 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5978 * syssignal.h (croak): Remove decl.
5979 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5980 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5981 now that we're termios-only.
5982 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5983 * term.c (dissociate_if_controlling_tty): Use #error rather than
5986 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5987 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5988 to work around GNOME bug 683906.
5989 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5990 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5991 This works around GCC bug 54561.
5993 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5995 More fixes for 'volatile' and setjmp/longjmp.
5996 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5997 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5998 (png_load_body) [HAVE_PNG]:
5999 (jpeg_load_body) [HAVE_JPEG]:
6000 New function, with most of the old parent function's body.
6001 (png_load) [HAVE_PNG]:
6002 (jpeg_load) [HAVE_JPEG]:
6003 Invoke the new function, to avoid longjmp munging our locals.
6004 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6005 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6006 longjmp is passed 2, as the C standard doesn't guarantee this.
6007 Instead, store the failure code into mgr->failure_code.
6009 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6011 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6012 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6013 (syms_of_keyboard): Remove support for unread-command-char.
6015 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6017 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6018 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6019 violation. (Bug#12426)
6021 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6023 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6025 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6027 * eval.c: Add `inhibit-debugger'.
6028 (Qinhibit_debugger): New symbol.
6029 (call_debugger): Bind it instead of Qdebug_on_error.
6030 (maybe_call_debugger): Test Vinhibit_debugger.
6031 (syms_of_eval): Define inhibit-debugger.
6032 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6033 (syms_of_xdisp): Remove inhibit-debug-on-message.
6035 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6037 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6038 If a nonvolatile local variable is written before a _longjmp to
6039 the frame containing the variable, and is read after the _longjmp,
6040 the value read is indeterminate. Some local variables of type
6041 'struct handler' and 'struct catchtag' are used in this way, so
6042 mark each of their slots as volatile if the slot can be set before
6043 _longjmp and read afterwards.
6044 * lisp.h (struct handler): var and chosen_clause are now volatile.
6045 (struct catchtag): val, next, and pdlcount are now volatile.
6047 * bidi.c (bidi_push_it, bidi_pop_it):
6048 * fns.c (copy_hash_table):
6049 * image.c (define_image_type):
6050 * keyboard.c (kbd_buffer_store_event_hold):
6051 * process.c (Fprocess_send_eof):
6052 * xfaces.c (x_create_gc) [HAVE_NS]:
6053 * xgselect.c (xg_select):
6054 Prefer assignment to memcpy when either will do.
6056 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6057 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6058 time an item is removed. No need to mark this function 'inline';
6059 the compiler knows better than we do.
6061 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6063 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6064 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6065 to change_frame_size (Bug#12388).
6066 (windowDidResize:): Pass YES to updateFrameSize.
6068 * nsterm.h: Add delay parameter to updateFrameSize.
6070 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6072 Discard killed buffers from deleted window and frame objects.
6073 This reduces an amount of references to killed buffers and
6074 helps GC to reclaim them faster.
6075 * alloc.c (discard_killed_buffers): New function.
6076 (mark_object): Use it for deleted windows and frames.
6077 (mark_object): If symbol's value is set up for a killed buffer
6078 or deleted frame, restore its global binding.
6079 * data.c (swap_in_global_binding): Add GC notice.
6080 (swap_in_symval_forwarding): Use convenient set_blv_where.
6081 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6082 * window.h: ... to here.
6084 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6086 Convenient macro to check whether the buffer is live.
6087 * buffer.h (BUFFER_LIVE_P): New macro.
6088 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6089 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6091 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6093 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6094 composition cases (Bug#12364).
6096 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6097 overhang of succeeding glyphs overlapping box cursor.
6099 * w32term.c (x_draw_glyph_string): Likewise.
6101 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6103 Simplify, document, and port floating-point (Bug#12381).
6104 The porting part of this patch fixes bugs on non-IEEE platforms
6105 with frexp, ldexp, logb.
6106 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6108 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6109 support, by removing commented-out code and briefly listing the
6110 C89 functions excluded. The commented-out stuff was confusing
6111 maintenance, e.g., we thought we needed cbrt but it was commented out.
6112 (logb): Remove decl; no longer needed.
6113 (isfinite): New macro, if not already supplied.
6114 (isnan): Don't replace any existing macro.
6115 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6116 are present on all C89 platforms.
6117 (Ffrexp): Do not special-case zero, as frexp does the right thing
6119 (Flogb): Do not use logb, as it doesn't have the desired meaning
6120 on hosts that use non-base-2 floating point. Instead, stick with
6121 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6122 frexp, to avoid getting an unspecified result.
6124 * xdisp.c (Qinhibit_debug_on_message): Now static.
6126 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6128 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6129 NSBezierPath (Bug#12131).
6131 2012-09-10 Chong Yidong <cyd@gnu.org>
6133 * fns.c (Fdelq, Fdelete): Doc fix.
6135 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6137 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6138 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6140 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6142 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6143 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6146 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6148 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6149 left fringe if the window has a left margin. This avoids leaving
6150 traces of the cursor because its leftmost pixel is not drawn over.
6152 * dispnew.c (update_window_line): When the left margin area of a
6153 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6154 that screen line. (Bug#12277)
6156 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6158 Assume C89 or later for math functions (Bug#12381).
6159 This simplifies the code, and makes it a bit smaller and faster,
6160 and (most important) makes it easier to clean up signal handling
6161 since we can stop worring about floating-point exceptions in
6162 library code. That was a problem before C89, but the problem
6163 went away many years ago on all practical Emacs targets.
6164 * data.c, image.c, lread.c, print.c:
6165 Don't include <math.h>; no longer needed.
6166 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6167 might be autoconfigured, as that never happens.
6169 * doprnt.c (DBL_MAX_10_EXP):
6170 * print.c (DBL_DIG):
6171 Remove. C89 or later always defines these.
6172 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6173 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6174 (arith_error, domain_error, domain_error2):
6175 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6176 no longer needed -- we simply return what C returns. All uses removed.
6177 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6179 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6180 Remove. All uses expanded, as these macros are no longer used
6181 more than once and are now more trouble than they're worth.
6182 (Ftan): Use tan, not sin / cos.
6183 (Flogb): Assume C89 frexp.
6184 (fmod_float): Assume C89 fmod.
6185 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6186 (init_floatfns): Remove. All uses removed.
6188 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6190 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6191 compositeToPoint for OSX < 10.6 (Bug#12390).
6193 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6195 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6196 This produces more-accurate results.
6198 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6200 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6201 changes (Bug#12088).
6203 2012-09-08 Chong Yidong <cyd@gnu.org>
6205 * syntax.c (Fstring_to_syntax): Doc fix.
6207 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6209 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6210 in the internal border.
6211 (x_set_window_size): Remove static variables and their usage.
6212 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6213 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6214 Remove fringe/internal border adjustment (Bug#11052).
6215 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6216 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6217 (ns_fix_rect_ibw): Remove.
6218 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6219 (ns_dumpglyphs_box_or_relief): Ditto.
6220 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6222 (ns_dumpglyphs_image): Ditto.
6223 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6225 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6226 their usage. Add fringe_extended_p and its use as in other terms.
6227 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6228 scroll bar was removed.
6229 (updateFrameSize): New function.
6230 (windowDidResize): Move code to updateFrameSize and call it.
6232 * nsterm.h (EmacsView): Add updateFrameSize.
6234 2012-09-07 Chong Yidong <cyd@gnu.org>
6236 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6238 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6240 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6242 More signal-handler cleanup (Bug#12327).
6243 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6244 Problem introduced when merging patches. Noted by Eli Zaretskii in
6245 <http://bugs.gnu.org/12327#67>.
6246 * floatfns.c: Comment fix.
6247 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6248 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6249 and anyway the declaration is harmless even if SIGDANGER is not defined.
6250 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6251 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6252 source files not surprisingly expected syssignal.h to define, or
6253 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6254 Include <sys/ioctl.h>, for FIONREAD.
6255 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6256 This eliminates a problem whereby other files mysteriously had
6257 to include "syssignal.h" before including "systty.h" if they
6258 wanted to use "#ifdef SIGIO".
6260 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6262 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6264 * w32.c (sigemptyset): Empty the set.
6265 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6267 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6269 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6271 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6272 (mark_object): Likewise for frame objects.
6274 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6276 * syssignal.h (handle_on_main_thread): Always declare,
6277 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6278 This ports to platforms without HAVE_PTHREAD.
6280 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6282 Signal-handler cleanup (Bug#12327).
6283 Emacs's signal handlers were written in the old 4.2BSD style with
6284 sigblock and sigmask and so forth, and this led to some
6285 inefficiencies and confusion. Rewrite these to use
6286 pthread_sigmask etc. without copying signal sets around. Also,
6287 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6288 'signal', and instead use functions that do not attempt to take
6289 over the system name space. This patch causes Emacs's text
6290 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6291 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6292 Do not include <signal.h> or "syssignal.h", as these
6293 modules do not use signals.
6294 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6295 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6296 Do not include <signal.h>, as "syssignal.h" does that for us now.
6297 * atimer.c (sigmask_atimers): New function.
6298 (block_atimers, unblock_atimers): New functions,
6299 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6301 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6302 no longer needed here.
6303 * emacs.c (main): Inspect existing signal handler with sigaction,
6304 so that there's no need to block and unblock SIGHUP.
6305 * sysdep.c (struct save_signal): New member 'action', replacing
6306 old member 'handler'.
6307 (save_signal_handlers, restore_signal_handlers):
6308 Use sigaction instead of 'signal' to save and restore.
6309 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6310 New function. All users of 'signal' modified to use set_sighandler
6311 if they're writeonly, and to use sys_signal if they're read+write.
6312 (emacs_sigaction_init, forwarded_signal): New functions.
6313 (sys_signal): Remove. All uses replaced by calls to sigaction
6314 and emacs_sigaction_init, or by direct calls to 'signal'.
6315 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6316 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6317 all uses replaced by pthread_sigmask etc. calls.
6318 * syssignal.h: Include <signal.h>.
6319 (emacs_sigaction_init, forwarded_signal): New decls.
6320 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6321 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6322 (sigmask, sys_sigmask): Remove; no longer needed.
6323 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6324 (sigblock, sigunblock, sigfree):
6325 (sigsetmask) [!defined sigsetmask]:
6326 Remove. All uses replaced by pthread_sigmask.
6327 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6328 no longer need to be replaced, and its typical old uses
6329 are now done via emacs_sigaction_init and sigaction.
6330 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6331 (sys_sigdel): Remove; unused.
6332 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6334 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6336 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6337 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6339 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6341 Explicitly mark buffer_defaults and buffer_local_symbols.
6342 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6343 mark_local_symbols here.
6344 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6345 since special buffers aren't marked here any more.
6346 (allocate_buffer): Chain new buffer with all_buffers here...
6347 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6349 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6350 (syms_of_buffer): Remove staticpro of the above.
6351 (init_buffer_once): Set names for buffer_defaults and
6352 buffer_local_symbols.
6354 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6356 Use bool for booleans in font-related modules.
6357 * font.c (font_intern_prop, font_style_to_value)
6358 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6359 (generate_otf_features, font_check_otf_features, font_check_otf)
6360 (font_match_p, font_list_entities, font_at):
6361 * fontset.c (fontset_id_valid_p, reorder_font_vector
6362 (fontset_find_font, Fset_fontset_font)
6363 (face_suitable_for_char_p) [0]:
6364 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6365 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6366 (m17n_flt_initialized, ftfont_shape_by_flt):
6367 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6368 * nsfont.m (nsfont_draw):
6369 * w32font.c (w32font_draw):
6370 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6371 Use bool for booleans.
6372 * font.h: Adjust to above API changes.
6373 (struct font, struct font_driver, struct font_driver_list):
6374 Use bool for booleans.
6375 (struct font): Remove useless member encoding_type.
6377 * fontset.c, xftfont.c: Omit unnecessary static decls.
6379 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6381 * alloc.c (mark_object): Revert window marking code
6382 since it's unsafe for the Fset_window_configuration.
6384 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6386 Fix race conditions with signal handlers and errno (Bug#12327).
6387 Be more systematic about preserving errno whenever a signal
6388 handler returns, even if it's not in the main thread. Do this by
6389 renaming signal handlers to distinguish between signal delivery
6390 and signal handling. All uses changed.
6391 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6392 * data.c (deliver_arith_signal): Rename from arith_error.
6393 * dispnew.c (deliver_window_change_signal): Rename from
6394 window_change_signal.
6395 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6396 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6397 * keyboard.c (deliver_input_available_signal): Rename from
6398 input_available_signal.
6399 (deliver_user_signal): Rename from handle_user_signal.
6400 (deliver_interrupt_signal): Rename from interrupt_signal.
6401 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6402 (deliver_child_signal): Rename from sigchld_handler.
6403 * atimer.c (handle_alarm_signal):
6404 * data.c (handle_arith_signal):
6405 * dispnew.c (handle_window_change_signal):
6406 * emacs.c (handle_fatal_signal, handle_danger_signal):
6407 * keyboard.c (handle_input_available_signal):
6408 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6409 * process.c (handle_pipe_signal, handle_child_signal):
6410 New functions, with the actual signal-handling code taken from the
6411 original respective signal handlers, sans the sporadic attempts to
6412 preserve errno, since that's now done by handle_on_main_thread.
6413 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6414 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6415 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6417 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6418 Move initialization of main_thread to sysdep.c's init_signals.
6419 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6420 our usage, and simplifies the mainline code.
6421 (record_child_status_change): New static function, as a helper
6422 for handle_child_signal, and with most of the old child handler's
6424 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6425 (handle_child_signal): Use the above.
6426 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6427 Moved here from emacs.c.
6428 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6429 code moved here from emacs.c's main function.
6430 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6431 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6432 This lets callers save and restore errno properly.
6434 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6436 Remove redundant or unused things here and there.
6437 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6438 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6439 * editfns.c (Fcompare_buffer_substrings): Likewise.
6440 * frame.h (struct terminal, struct font_driver_list):
6441 Remove redundant declarations.
6442 * window.h (Qleft, Qright): Likewise.
6444 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6446 Do not mark objects from deleted buffers, windows and frames.
6447 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6448 (mark_object): Likewise for windows and frames.
6450 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6452 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6453 buffer_defaults and buffer_local_symbols as valid objects.
6454 Return special value to denote them.
6456 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6458 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6459 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6460 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6461 (file_name_absolute_p, Fsubstitute_in_file_name):
6462 (check_executable, check_writable, Ffile_accessible_directory_p)
6463 (Fset_file_selinux_context, Fdefault_file_modes)
6464 (Finsert_file_contents, choose_write_coding_system)
6465 (Fwrite_region, build_annotations, a_write, e_write)
6467 * filelock.c (boot_time_initialized, get_boot_time)
6468 (get_boot_time_1, lock_file_1, within_one_second):
6469 * floatfns.c (in_float):
6470 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6471 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6472 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6473 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6474 * window.c (compare_window_configurations):
6475 Use bool for booleans.
6476 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6477 (Fdefault_file_modes): Now mode_t, not int, for modes.
6478 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6479 (internal_delete_file): Now returns void, not a (boolean) int,
6480 since nobody was looking at the return value.
6481 * lisp.h, window.h: Adjust to above API changes.
6483 * xdisp.c (set_message): Simplify and reindent last change.
6485 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6487 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6489 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6491 * eval.c (call_debugger): Make the function non-static so that we
6492 can call it from set_message.
6494 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6495 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6497 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6499 Give more-useful info on a fatal error (Bug#12328).
6500 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6501 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6502 of doing the work ourselves.
6503 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6504 do most of the work.
6505 (fatal_error_backtrace): New function, taken from the guts
6506 of the old fatal_error_signal, but with a new option to output
6508 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6509 info about the signal than just its number.
6510 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6511 * sysdep.c: Include <execinfo.h>
6512 (emacs_backtrace): New function, taken partly from the previous
6513 code of the 'die' function.
6514 (emacs_abort): Call fatal_error_backtrace rather than abort.
6516 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6518 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6519 eager (load-time) macro-expansion.
6520 * lisp.mk (lisp): Add macroexp.
6522 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6524 Simplify redefinition of 'abort' (Bug#12316).
6525 Do not try to redefine the 'abort' function. Instead, redo
6526 the code so that it calls 'emacs_abort' rather than 'abort'.
6527 This removes the need for the NO_ABORT configure-time macro
6528 and makes it easier to change the abort code to do a backtrace.
6529 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6530 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6531 Remove; sysdep.c's emacs_abort now takes its place.
6532 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6533 'abort' changed to use 'emacs_abort'.
6534 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6535 (abort) [!defined abort]: Rename to ...
6536 (emacs_abort): ... new name.
6537 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6538 the place of the old 'abort' in emacs.c.
6539 * w32.c, w32fns.c (abort): Do not #undef.
6540 * w32.c (emacs_abort): Rename from w32_abort.
6542 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6544 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6545 offsets[j].dv, since the y axis of the screen coordinates points
6546 down, while the y axis of the font definition coordinates points
6547 up. This fixes display of Arabic diacritics such as KASRA and
6548 KASRATAN. (Bug#11860)
6550 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6552 Be more systematic about _setjmp vs setjmp.
6553 * alloc.c (test_setjmp, mark_stack):
6554 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6555 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6556 (png_load, my_error_exit, jpeg_load):
6557 * process.c (send_process_trap, send_process):
6558 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6559 The underscored versions are up to 30x faster on some hosts.
6560 Formerly, the code used setjmp+longjmp sometimes and
6561 _setjmp+_longjmp at other times, with no particular reason to
6562 prefer setjmp+longjmp.
6564 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6566 Fix minor problem found by static checking.
6567 * buffer.c (Fdelete_all_overlays): Return nil.
6569 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6571 * buffer.c (Fdelete_all_overlays): New function.
6573 2012-09-03 Chong Yidong <cyd@gnu.org>
6575 * gtkutil.c: Add extern decl for Qxft.
6577 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6579 * emacs.c, eval.c: Use bool for boolean.
6580 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

6588 * process.c (read_process_output, exec_sentinel):
6589 Use bool for booleans.
6590 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
6591 All callers changed.
6592 * eval.c (interactive_p): Omit always-true boolean argument
6593 EXCLUDE_SUBRS_P. All callers changed.
6594 * dispextern.h, lisp.h: Reflect above API changes.
6595 * firstfile.c (dummy): Use the address of 'main', whose signature
6596 won't change, instead of the address of 'initialize', whose
6597 signature just changed from int to bool.
6598 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6599 * msdos.c (fatal_error_in_progress): ... from here.
6600 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6602 (redisplay_internal, unwind_redisplay): Simply clear
6603 REDISPLAYING_P when unwinding, instead of saving its previous,
6604 always-false value and then restoring it.
6606 Clean up some extern decls.
6607 Mostly, this hoists extern decls out of .c files and into .h files.
6608 That way, we're more likely to catch errors if the interfaces change.
6609 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6610 declare xg_mark_data.
6611 * dispextern.h (x_frame_parm_handlers):
6613 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
6614 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
6615 (Qultra_bold, Qoblique, Qitalic):
6616 Move extern decl here from .c file.
6617 * alloc.c (xg_mark_data) [USE_GTK]:
6619 * eval.c (Qlexical_binding):
6620 * fns.c (time) [!HAVE_UNISTD_H]:

6626 * process.c (QCfamily, QCfilter):
6627 * widget.c (free_frame_faces):
6628 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
6629 * xfont.c (x_clear_errors):
6630 * xterm.c (x_frame_parm_handlers):
6631 Remove now-redundant extern decls.
6632 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6633 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6635 * xfaces.c: Remove unnecessary static decls.
6636 * xterm.c (updating_frame): Remove decl of nonexistent object.
6638 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6639 when building globals.h, as the objects that are not built on
6640 this host are not needed to compile C files on this host.
6642 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6644 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

6652 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
6653 (Fsubstitute_command_keys):

6655 (save_excursion_save, save_excursion_restore)
6656 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
6657 (format_time_string, general_insert_function)
6658 (make_buffer_string, make_buffer_string_both)
6659 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
6660 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)
6661 (copy_text, insert_1, insert_1_both, insert_from_string)
6662 (insert_from_string_before_markers, insert_from_string_1)

6669 (adjust_for_invis_intang, set_point_both)
6670 (get_property_and_range, compare_string_intervals)
6671 (set_intervals_multibyte_1, set_intervals_multibyte):
6672 * keyboard.c (decode_timer):
6673 Use bool for boolean.
6674 * intervals.h, lisp.h, systime.h: Reflect above API changes.
6675 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
6677 2012-09-02 Chong Yidong <cyd@gnu.org>
6679 * keymap.c (push_key_description): Print M-TAB as C-M-i
6682 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
6684 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
6685 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

6690 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
6692 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6694 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6695 more than one grapheme cluster passed to the shaper: compute the
6696 offset adjustment values separately for each cluster. (Bug#11860)
6698 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6699 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6700 about implicit conversions from integer to pointer.
6702 2012-09-01 Daniel Colascione <dancol@dancol.org>
6704 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6705 system used too early.
6707 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
6709 Better seed support for (random).
6710 * emacs.c (main): Call init_random.

6724 all of which have been moved to common code.
6726 * xfaces.c: Include TERM_HEADER instead of listing all possible
6727 window-system headers.
6729 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

6733 directly accessing frame internals.
6735 * w32font.h: Include font.h. Define syms_of_w32font and
6738 * process.c: Include TERM_HEADER instead of listing all possible
6739 window-system headers.
6741 * nsterm.h: Remove declarations now in frame.h.
6742 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
6744 * menu.c: Include TERM_HEADER instead of listing all possible
6745 window-system headers.
6747 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
6750 * keyboard.c: Include TERM_HEADER instead of listing all possible
6751 window-system headers.
6753 * image.c: Include TERM_HEADER instead of listing all possible
6754 window-system headers. Declare Vlibrary_cache when compiling for
6757 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
6758 window system declarations.
6760 * frame.h: Move common functions here: set_frame_menubar,
6761 x_set_window_size, x_sync, x_get_focus_frame,
6762 x_set_mouse_position, x_set_mouse_pixel_position,
6763 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
6764 x_char_width, x_char_height, x_pixel_width, x_pixel_height,
6765 x_set_frame_alpha, x_set_menu_bar_lines, x_set_tool_bar_lines,

6783 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
6784 the current window system; include in list of objects to link into
6787 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6789 Remove mark_ttys function and fix tty_display_info initialization.
6790 * lisp.h (mark_ttys): Remove prototype.
6791 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
6792 to mark_ttys because all possible values of 'top_frame' slot are
6793 the frames which are reachable from Vframe_list.
6794 * term.c (mark_ttys): Remove.
6795 (init_tty): Safely initialize 'top_frame' slot with Qnil.
6797 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6799 Change struct frame bitfields from unsigned char to unsigned.
6800 * frame.h (struct frame): Change type of 'display_preempted',
6801 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
6802 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
6803 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
6804 bitfields from unsigned char to unsigned.
6806 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6808 Remove unused member of struct x_output and struct w32_output.
6809 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.

6812 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
6814 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
6815 does not become zero (Bug#12234).
6817 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
6819 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6820 for GCC 4.7.1 x86-64.
6822 2012-08-30 Glenn Morris <rgm@gnu.org>
6824 * lread.c (init_lread): For out-of-tree builds, only add the
6825 source directory's site-lisp dir to the load-path if it exists,
6826 consistent with in-tree builds. (Bug#12302)
6828 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
6830 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
6831 button_values to NULL. Call setStykeMask so dialogs get a close button.
6832 (windowShouldClose:): Set window_closed.
6833 (dealloc): New member, free button_values.
6834 (process_dialog:): Make member function. Remove window argument,
6835 replace window with self. Count buttons and allocate and store values
6837 (addButton:value:row:): value is int with the name tag. Call setTag
6838 with tag. Remove return self, declare return value as void.
6839 (addString:row:): Remove return self, declare return value as void.
6840 (addSplit): Remove return self, declare return value as void.
6841 (clicked:): Remove return self, declare return value as void.
6842 Set dialog_return to button_values[seltag]. Code formatting change.
6843 (initFromContents:isQuestion:): Adjust call to process_dialog.
6844 Code formatting change.
6845 (timeout_handler:): Set timer_fired to YES.
6846 (runDialogAt:): Set timer_fired to NO.
6847 Handle click on close button as quit.
6849 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6850 Add window_closed and button_values. Add void as return value for
6851 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6852 Add process_dialog as new member.
6854 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6856 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
6857 is not one of the heaps we manage. (Bug#12242)
6859 2012-08-28 Glenn Morris <rgm@gnu.org>
6861 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

6872 * buffer.c (Fset_buffer_major_mode): Signal an error
6873 if the buffer is dead.
6874 (Fother_buffer, other_buffer_safely): Remove redundant
6877 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
6879 Always use set_buffer_if_live to restore original buffer at unwind.
6880 * buffer.h (record_unwind_current_buffer): New function.
6881 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
6882 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
6883 * undo.c, window.c: Adjust users.
6884 * buffer.c (set_buffer_if_live): Fix comment.
6886 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
6888 Fix usage of set_buffer_internal.
6889 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
6890 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
6891 * coding.c (decode_coding): Omit redundant test.

6895 * keyboard.c (command_loop_1): Likewise.
6896 * print.c (PRINTFINISH): Likewise.
6897 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
6899 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

6917 (change_frame_size_1, sit_for):
6918 Use bool for boolean.
6919 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
6920 and remove last int (actually boolean) argument, which was always 0.
6921 All callers changed.
6922 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
6923 * dispextern.h (struct composition_it): Use bool for boolean.
6924 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
6925 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
6926 * dired.c (file_name_completion):
6927 Use bool for boolean. (This was missed in an earlier change.)
6929 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6931 * window.c (Fset_window_configuration): Revert first part of
6934 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
6936 * nsterm.h (NSPanel): New class variable dialog_return.
6938 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
6939 Initialize dialog_return.
6940 (windowShouldClose:): Use stop instead of stopModalWithCode.
6941 (clicked:): Ditto, and also set dialog_return (Bug#12258).
6942 (timeout_handler:): Use stop instead of abortModal. Send a dummy
6944 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
6947 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

6959 Use bool for booleans.
6960 * dired.c (file_name_completion):
6961 * process.h (fd_callback):
6962 Omit int (actually boolean) argument. It wasn't being used.
6964 * composite.h, lisp.h: Reflect above API changes.

6988 * fileio.c (Finsert_file_contents):
6989 Use bool for booleans.
6990 * coding.h, lisp.h: Reflect above API changes.
6991 * coding.c: Remove unnecessary static function decls.
6992 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6993 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6994 not a boolean 'int', since callers never look at the return value.
6995 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
6996 * coding.h (decoding_buffer_size, encoding_buffer_size)
6997 (emacs_mule_string_char): Remove unused extern decls.
6998 (struct iso_2022_spec, struct coding_system):
6999 Use 'unsigned int : 1' for boolean fields, since there's more than one.
7000 (struct emacs_mule_spec): Remove unused field 'full_support'.
7001 All initializations removed.
7002 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
7004 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7006 Fix spare memory change (Bug#12286).
7007 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7008 (valid_lisp_object_p): Likewise.
7010 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7012 * window.c (Fset_window_configuration): Record any window's old
7013 buffer if it's replaced (see Bug#8789). If the new current
7014 buffer doesn't appear in the selected window, go to its old
7017 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7019 Special MEM_TYPE_SPARE to denote reserved memory.
7020 * alloc.c (enum mem_type): New memory type.
7021 (refill_memory_reserve): Use new type for spare memory.
7022 This prevents live_cons_p and live_string_p from incorrect
7023 detection of uninitialized objects from spare memory as live.
7025 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7028 * Makefile.in (.PHONY): versioclean -> versionclean.
7030 Remove unused external symbols.
7031 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7032 * window.c (Qwindow_valid_p, decode_valid_window):
7033 Now static, not extern.
7034 * data.c (Qinterval): Remove; unused.
7035 (syms_of_data): Do not define 'interval'.
7036 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7037 * window.h (decode_valid_window):
7040 * character.c, charset.c, chartab.c: Use bool for booleans.
7041 * character.c (lisp_string_width, string_count_byte8)
7042 (string_escape_byte8):

7050 (char_table_set_range, optimize_sub_char_table)
7051 (map_sub_char_table):
7052 Use bool for boolean.
7053 * character.c (str_to_unibyte): Omit last boolean argument; it was
7054 always 0. All callers changed.
7055 * character.h, charset.h: Adjust to match previous changes.
7056 * character.h (char_printable_p): Remove decl of nonexistent function.
7057 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7058 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7059 are all boolean, so make them single-bit bitfields.
7061 * lisp.h (ASET): Remove attempt to detect side effects.
7062 It was meant to be temporary and it often doesn't work,
7063 because when IDX has side effects the behavior of IDX==IDX
7064 is undefined. See Stefan Monnier in
7065 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7067 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7069 * lisp.h (functionp): New function (extracted from Ffunctionp).
7070 (FUNCTIONP): Use it.
7071 * eval.c (Ffunctionp): Use it.
7073 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7075 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7076 as that's faster and simpler than static storage. Don't bother
7077 with the g_main_context_query overhead if g_main_context_pending
7078 says no events are pending.
7079 (gfds, gfds_size): Remove these static vars.
7080 (xgselect_initialize): Remove; no longer needed.
7081 All uses and decls removed.
7083 * emacs.c (fatal_error_signal_hook): Remove.
7084 All uses removed. This leftover from old code was always 0.
7086 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7087 * casefiddle.c (casify_object, casify_region):
7088 * casetab.c (set_case_table):
7089 * category.c, category.h (word_boundary_p):
7090 * category.h (CHAR_HAS_CATEGORY):
7091 Use bool for booleans, instead of int.
7093 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7095 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7097 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7099 On assertion failure, print backtrace if available.
7100 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7101 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7102 * Makefile.in (LIB_EXECINFO): New macro.
7105 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7106 * bytecode.c (exec_byte_code):
7107 * callint.c (check_mark, Fcall_interactively):
7108 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7109 (getenv_internal, sync_process_alive, call_process_exited):
7110 * lisp.h (USE_SAFE_ALLOCA):
7111 Use bool for booleans, instead of int.
7112 * lisp.h, process.h: Adjust prototypes to match above changes.
7113 * callint.c (Fcall_interactively): Don't assume the mark's
7114 offset fits in 'int'.
7116 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7118 * buffer.c, buffer.h: Use bool for boolean.
7119 * buffer.c (reset_buffer_local_variables)
7120 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7121 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

7123 (overlay_touches_p, overlay_strings, Foverlay_put)
7124 (report_overlay_modification, call_overlay_mod_hooks):
7125 (mmap_enlarge, mmap_set_vars):
7126 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7127 Use bool for booleans, instead of int.
7128 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7129 since the 1-or-0 return value is always ignored anyway.
7130 (mmap_initialized_p):
7131 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7132 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7134 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7136 * bidi.c: Use bool for boolean.
7137 This is a bit more readable, and makes the text segment of bidi.o
7138 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7139 Presumably it's faster too.
7140 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7142 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7143 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7144 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7145 (bidi_explicit_dir_char, bidi_level_of_next_char)
7146 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7147 Use bool for booleans, instead of int.
7148 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7149 (bidi_unshelve_cache): Adjust decls to match code.
7151 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7153 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7156 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7158 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7159 * atimer.h: Include <stdbool.h>.
7161 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7163 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7164 compile time tests instead of run time tests on systems that do
7166 (FRAME_MAC_P): Remove leftover from deleted code.
7167 * frame.c (syms_of_frame): Remove leftover from deleted code.
7169 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7171 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7173 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7175 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7176 Otherwise, the compiler complains about (A?B:C) where B is void
7177 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7178 (fontset_add): Return void, for FONTSET_ADD.
7180 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7182 * alloc.c: Use bool for booleans.
7183 (gc_in_progress, abort_on_gc)
7184 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7185 (dont_register_blocks) [GC_MALLOC_CHECK]:
7186 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7187 (check_string_bytes, make_specified_string, memory_full)
7188 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7189 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7190 (mark_stack, valid_pointer_p, make_pure_string)
7191 (Fgarbage_collect, survives_gc_p, gc_sweep):
7192 Use bool for booleans, instead of int.
7193 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7194 Remove unused local.
7195 * alloc.c (PURE_POINTER_P):
7196 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7197 * editfns.c (Fformat):
7198 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7200 * fns.c (sweep_weak_table):
7201 * lisp.h (suppress_checking, push_message, survives_gc_p)
7202 (make_pure_string, gc_in_progress, abort_on_gc):
7203 * lread.c (readchar, read1):
7204 * print.c (Fprin1_to_string):
7205 * xdisp.c (push_message):
7206 Use bool for booleans affected directly or indirectly by
7209 Make recently-introduced setters macros.
7210 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7211 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7212 (set_fontset_default, set_fontset_fallback): Rename from their
7213 upper-case counterparts, and make them functions rather than macros.
7214 This is more consistent with the other recently-introduced setters.
7215 These don't need to be inline, since they're local.
7217 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7219 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7220 the loop (Bug#12247).
7222 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7224 * lisp.h (vcopy): Use memcpy rather than our own loop.
7225 This fixes a performance regression introduced by the recent
7226 addition of vcopy. This means 'vcopy' will need to be modified
7227 for a copying collector, but that's OK. Also, tighten the
7228 checking in the assertion.
7230 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7232 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7233 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7234 non-base glyph for the width of the base character, according to
7235 what x_draw_composite_glyph_string_foreground expects.
7236 Generate WADJUST value according to composition_gstring_width's
7237 expectations, to produce correct width of the composed character.
7238 Reverse the sign of the DU offset produced by ScriptPlace.
7240 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7242 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7244 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7246 Avoid direct writes to contents member of struct Lisp_Vector.
7247 * lisp.h (vcopy): New function to copy data into vector.
7248 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7249 * fns.c (Ffillarray): Use ASET.
7250 * keyboard.c (timer_check_2): Use AREF and ASET.
7251 (append_tool_bar_item, Frecent_keys): Use vcopy.
7252 * lread.c (read_vector): Use ASET.
7253 * msdos.c (Frecent_doskeys): Use vcopy.
7254 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7255 (Finternal_merge_in_global_face): Use ASET and vcopy.
7256 * xfont.c (xfont_list_pattern): Likewise.
7258 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7260 * window.c (Fwindow_point): For the selected window always return
7261 the position of its buffer's point.
7262 (Fset_window_point): For the selected window always go in its
7263 buffer to the specified position.
7265 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7267 Setter macros for fontsets.
7268 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7269 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7270 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7273 2012-08-20 Glenn Morris <rgm@gnu.org>
7275 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7276 Don't assume that `ln -f' works.
7278 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7280 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7281 and later about non-assignments with no effect. See discussion at
7282 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7285 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7287 Inline setter functions for Lisp_Objects slots of struct specbinding.

7324 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7326 Rely on <config.h> + <unistd.h> to declare 'environ',
7327 as gnulib does this if the system doesn't.
7328 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

8197 2012-08-04 Eli Zaretskii <eliz@gnu.org>
8199 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
8200 * w32.c (init_environment): Change the default values of many
8201 environment variables in dflt_envvars[] to NULL, to avoid pushing
8202 them into environment when they were not already defined.
8203 Remove the code that deletes site-lisp subdirectories from the default
8204 value of EMACSLOADPATH, as it is no longer needed.
8205 (check_windows_init_file): Now external, not static.
8206 Use Vload_path as is, without adding anything, as this function is now
8207 called when Vload_path is already set up.
8209 * w32.h (check_windows_init_file): Add prototype.
8211 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
8212 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
8213 compatibility with Posix platforms.
8214 (main): Move the call to check_windows_init_file to here from
8216 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
8217 any, in the DEFALT argument into the root of the Emacs build or
8218 installation tree, as appropriate.
8220 * callproc.c (init_callproc_1): Call decode_env_path instead of
8221 doing its equivalent by hand.
8222 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
8223 the code that sets Vexec_path run on MS-Windows.
8225 * lread.c (init_lread): Add comments to #ifdef's.
8227 * msdos.c (dos_set_window_size, IT_update_begin)
8228 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
8229 instead of direct references.

8233 Export DEFAULT_REHASH_* to GDB.
8234 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
8235 Now constants, not macros.
8237 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
8239 Remove unnecessary casts involving pointers.
8240 These casts are no longer needed now that we assume C89 or later,
8241 since they involve casting to or from void *.
8242 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
8243 (make_pure_float, make_pure_vector):
8244 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

8253 (x_get_window_property, x_get_window_property_as_lisp_data):
8254 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8255 Remove unnecessary pointer casts.
8256 * alloc.c (record_xmalloc): New function.
8257 * lisp.h (record_xmalloc): New decl.
8258 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8259 more like a function. This is because the pointer cast is not
8260 needed. All uses changed.
8261 * print.c (print_string, print_error_message): Avoid length recalc.
8263 Improve fix for macroexp crash with debugging (Bug#12118).
8264 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8265 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8266 not supposed to be invoked from the garbage collector.
8267 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
8268 (gc_aset): New function, which is like ASET but can be
8269 used in the garbage collector.
8270 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

8280 <g_b_init_create_symbolic_link>: New static flags.
8281 (globals_of_w32): Initialize them to zero.
8282 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
8283 (map_w32_filename): Improve commentary. Simplify switch.
8284 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
8285 headers (most versions of MinGW w32api don't).
8286 (get_security_info, create_symbolic_link)
8287 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
8289 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
8290 in the argument file name.
8291 (sys_access): Call unc_volume_file_attributes only if

8293 (sys_rename): Diagnose renaming of a symlink when the user doesn't
8294 have the required privileges.
8295 (get_file_security_desc_by_name): Rename from
8296 get_file_security_desc.
8297 (stat_worker): New function, with most of the guts of 'stat', and
8298 with addition of handling of symlinks and support for 'lstat'.
8299 If possible, get file's attributes and security information by
8300 handle, not by name. Produce S_IFLNK bit for symlinks, when
8301 called from 'lstat'.
8302 (stat, lstat): New functions, call 'stat_worker'.
8303 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8304 symlinks when the underlying filesystem supports them.
8306 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8308 Fix macroexp crash on Windows with debugging (Bug#12118).
8309 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8310 checking subscripts; problem introduced with the recent
8311 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8312 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8313 since it's used in non-static inline functions now.
8315 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8316 Don't assume buffer size fits in 'int'. Remove unused local.
8318 Use C99-style 'extern inline' if available.

8330 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
8331 * alloc.c (LISP_INLINE):

8333 * category.c (CATEGORY_INLINE):
8334 * character.c (CHARACTER_INLINE):
8335 * charset.c (CHARSET_INLINE):
8336 * composite.c (COMPOSITE_INLINE):
8337 * dispnew.c (DISPEXTERN_INLINE):
8338 * sysdep.c (SYSTIME_INLINE):
8339 Define to EXTERN_INLINE, so that the corresponding functions
8340 are compiled into code.
8341 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8342 (INLINE_HEADER_END): New macros.
8343 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8363 hard-coding the path separator.
8365 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8367 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8368 This how ASET and AREF are supposed to work, and makes
8369 it easier to think about future improvements. See
8370 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8371 * charset.h (set_charset_attr): New function.

8625 does that unconditionally. Remove file, which is now empty.
8627 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
8630 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

8748 * w32inevt.c: Include w32inevt.h.
8749 (w32_read_console_input): New inline function, calls either

8751 w32_console_unicode_input.
8752 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
8753 (w32_kbd_patch_key, key_event): Use the codepage returned by
8754 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

8786 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
8787 enumeration constants, as PURE and HEAP are too general, and clash
8788 with other headers and sources, such as gmalloc.c and the
8789 MS-Windows system headers. All users changed.
8791 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8793 Revert last save_excursion_save and save_excursion_restore changes.
8794 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

8807 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8808 arms of an 'if', not using conditional expressions; otherwise GDB
8809 complains about the types in the unevaluated arm when the argument
8810 is an integer literal.
8811 (xgetint): Simplify expression.
8812 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8813 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8814 Zaretskii in <http://bugs.gnu.org/12036#13>.
8815 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8816 needed now that we have gdb_make_enums_visible.
8817 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8818 (enum enum_USE_LSB_TAG):
8819 New enum types, packaging up enums that need to be exported to GDB.

8838 * xfns.c (syms_of_xfns): Likewise.
8840 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

8843 * lisp.h (struct Lisp_Excursion): New data type.
8844 (PVEC_EXCURSION): New pseudovector type.
8845 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
8846 to deal with it. Adjust comments.

8861 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8862 emacs.c, as this is a more-suitable home. Had this been done earlier
8863 the fix for 12036 would have avoided some of the problems noted in
8864 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8865 would have been more obvious.
8866 * emacs.c: Do not include <verify.h>; no longer needed.
8867 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8868 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8869 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

8874 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
8875 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8876 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8877 not be usable in #if. This simplifies things.
8879 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8881 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
8883 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

8886 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8887 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8888 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8889 Adjust to changes in lisp.h and emacs.c, by using
8890 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8891 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8892 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8893 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8894 instead of gdb_valbits.
8895 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8896 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8897 instead of gdb_array_mark_flag.
8898 (xboolvector): Get size from $->size, not $->header.size.
8899 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8900 (xreload, hook-run, hookpost-run): Remove.
8901 * emacs.c: Include <verify.h>.
8902 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8903 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8905 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8906 (gdb_USE_LSB_TAG): New enum constants.
8907 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8908 Also define these as enum constants, so they're visible to GDB.
8909 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8910 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8911 as constants, so they're visible to GDB.
8912 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
8913 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
8914 Now enum constants, not macros, so they're visible to GDB.
8915 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8916 more convenient now. All uses changed.
8917 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8918 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8920 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8925 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
8927 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8928 add argument, tune behavior, and adjust all callers.
8930 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8932 Use typedef for EMACS_INT, EMACS_UINT.
8933 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8934 than macros. This simplifies debugging in the usual case, since
8935 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8936 and it allows expressions involving EMACS_INT casts.
8937 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8939 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8949 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
8951 Adjust buffer text indirection counters at the end of Fkill_buffer.
8952 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8953 buffer is definitely dead. This should really fix an issue reported
8954 by Christoph Scholtes again. (Bug#12007).
8955 (init_buffer_once): Initialize indirection counters of
8956 buffer_defaults and buffer_local_symbols (for sanity and safety).
8958 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8960 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8961 and continuation glyphs on tooltip frames, leave them at zero.
8962 Avoids continued lines in tooltips. (Bug#11832)
8964 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
8966 Simplify copy_overlay.
8967 * buffer.c (copy_overlay): Simplify. Use build_marker.

8973 or invalid. (Bug#12025)
8975 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
8976 it signals an error when a tooltip frame is being created.
8978 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8980 Cleanup miscellaneous objects allocation and initialization.
8981 * alloc.c (allocate_misc): Change to static. Add argument to
8982 specify the subtype. Adjust comment and users.

8984 * buffer.c (copy_overlays, Fmake_overlay): Use it.
8985 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
8986 (allocate_misc): Remove prototype.
8987 (build_overlay): Add prototype.
8989 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8991 Swap buffer text indirection counters in Fbuffer_swap_text.
8992 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8993 This avoids crash reported by Christoph Scholtes at
8994 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8996 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8998 * nsmenu.m (Popdown_data): New struct.
8999 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
9001 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
9002 (initWithContentRect): Make imgView and contentView non-static
9003 and autorelease them. Also autorelease img and matrix (Bug#12005).
9004 (dealloc): Remove (Bug#12005).
9006 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9008 Adjust consing_since_gc when objects are explicitly freed.
9009 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
9010 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
9011 (free_cons, free_misc): Subtract object size from consing_since_gc.
9013 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>

9017 (live_buffer, set_marker_internal): New function.
9018 (Fset_marker, set_marker_restricted): Use set_marker_internal.
9019 (set_marker_both, set_marker_restricted_both): Use live_buffer.
9021 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9023 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9024 as it's limited by the amount of memory, not by INT_MAX.
9026 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9028 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9029 in special-event-map. See the discussion at

9033 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
9034 info.dwItemData. Fixes crashes on 64-bit Windows.

9752 * s/aix4-2.h (unix): Remove; no longer needed.
9754 EMACS_TIME simplification (Bug#11875).
9755 This replaces macros (which typically do not work in GDB)

9757 The functional style also makes code easier to read and maintain.
9758 * systime.h: Include <sys/time.h> on all hosts, not just if
9759 WINDOWSNT, since 'struct timeval' is needed in general.

9799 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9800 Prefer snprintf to strncpy.
9801 * nsterm.m (ns_term_init):
9802 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9803 * nsterm.m (ns_term_init):
9804 Avoid the need for strncpy, by using build_string or
9805 make_unibyte_string directly. Use dtoastr, not snprintf.
9806 * process.c (Fmake_network_process): Diagnose service names that
9807 are too long, rather than silently truncating them or creating
9808 non-null-terminated names.
9809 (Fnetwork_interface_info): Likewise, for interface names.
9810 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9811 Prefer sprintf to strncat.

9825 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9826 where argument type is known to be a Lisp_Cons.

9881 O_RDONLY already includes it).
9883 Stop ns builds setting the EMACSLOADPATH environment variable.
9884 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9885 Now it does not set EMACSLOADPATH, just returns the load-path string.
9886 * nsterm.h: Update accordingly.
9887 * lread.c [HAVE_NS]: Include nsterm.h.
9888 (init_lread) [HAVE_NS]: Use ns_load_path.

9898 (ns_init_paths): Do not set EMACSPATH.

9952 * nsterm.h (ns_etc_directory): Add it.
9953 * callproc.c [HAVE_NS]: Include nsterm.h.
9954 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
9956 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
9958 Move marker debugging code under MARKER_DEBUG.
9959 * marker.c (MARKER_DEBUG): Move marker debugging code under
9960 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9961 for bootstrap with --enable-checking (~3x slowdown reported
9962 by Juanma Barranquero <lekktu@gmail.com>).
9963 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
9965 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
9967 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
9968 See <http://bugs.gnu.org/11825#29>.
9970 2012-07-08 Eli Zaretskii <eliz@gnu.org>
9972 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
9973 has no font, use the frame's font. (Bug#11813)
9974 (display_line): Add commentary about displaying truncation glyphs
9976 (produce_special_glyphs): Move here from term.c.
9978 * term.c (produce_special_glyphs): Move to xdisp.c.
9980 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
9983 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
9985 * xdisp.c (display_line): Avoid warning about implicit declaration
9988 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
9990 * lisp.h: Remove empty conditional.
9992 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9994 * lread.c (load_path_check): Now static.
9996 Fix some minor --with-ns problems found by static checking.
9997 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
9998 (x_set_font) [!HAVE_X_WINDOWS]:
9999 * image.c (xpm_load_image) [HAVE_NS]:
10000 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10001 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10002 Remove unused local.
10003 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10004 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10005 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10006 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10007 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10008 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10009 Fix pointer signedness problem.
10010 * xfaces.c (FRAME_X_FONT_TABLE):
10011 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10013 2012-07-07 Glenn Morris <rgm@gnu.org>
10015 * lread.c (load_path_check): New function, split from init_lread.
10016 (init_lread): Reorganize. Motivation:
10017 If EMACSLOADPATH is set, check/warn about that rather than the
10018 defaults, which we are not going to use. Hence we can remove
10019 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10020 Don't warn if site-lisp directories are missing.
10021 If not installed, start from a blank load-path, since
10022 PATH_LOADSEARCH refers to the eventual installation directories.
10024 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10026 Support truncation and continuation glyphs on GUI frames, when
10027 fringes are disabled. (Bug#11832)
10028 * xdisp.c (init_iterator): Get dimensions of truncation and
10029 continuation glyphs even if on GUI frames.
10030 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10031 or both, are absent.
10032 (start_display, move_it_in_display_line_to): Handle the case of a
10033 GUI frame without a fringe to display continuation or truncation
10035 (insert_left_trunc_glyphs): Support GUI frames: make sure
10036 truncation glyphs overwrite enough glyphs from the current line to
10037 have sufficient space in pixels.
10038 (display_line): Support truncation and continuation glyphs on GUI
10039 frames. If some spare pixels are left on the line after inserting
10040 the truncation glyphs, fill that space with a stretch glyph of a
10041 suitably computed width.
10043 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10044 produce_glyphs, to support GUI sessions.
10046 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10048 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10050 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10052 Do not require float-time's arg to fit in time_t (Bug#11825).
10053 This works better on hosts where time_t is unsigned, and where
10054 float-time is applied to the (negative) difference between two times.
10055 * editfns.c (decode_time_components): Last arg is now double *,
10056 not int *, and means to store all the result as a double, without
10057 worrying about whether the seconds part fits in time_t.
10058 All callers changed.
10059 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10060 All callers changed.
10061 (Ffloat_time): Do not fail merely because the specified time falls
10062 outside of time_t range.
10064 2012-07-07 Glenn Morris <rgm@gnu.org>
10066 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

10068 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10070 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10072 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10073 Update dependencies.

10081 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10082 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10083 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10084 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10086 * xfont.c (compare_font_names): Redo to omit the need for casts.
10088 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10090 * xfns.c (Fx_change_window_property): Doc fix.
10091 * w32fns.c (Fx_change_window_property): Doc fix.
10093 * w32fns.c (Fx_window_property): Accept the same arguments as the
10094 X Windows version. Doc fix.
10095 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10097 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10098 Eli Zaretskii <eliz@gnu.org>
10100 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10101 Windows-specific code from nt/config.nt moved here.
10102 Obsolete settings removed.
10104 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10106 * process.c: Avoid unnecessary calls to gettime.
10107 (wait_reading_process_output): Don't get the time of day
10108 when gobbling data immediately and not waiting, as there's no need
10109 for it in that case. This removes a FIXME.
10111 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10113 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10114 is defined (Bug#11768).
10116 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10118 Fix marker debugging code.
10119 * marker.c (byte_char_debug_check): Do not perform the check
10120 if buffer is not multibyte.
10121 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10122 Call byte_char_debug_check with correct arguments.
10124 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10126 Compile marker debugging code only if ENABLE_CHECKING is defined.
10127 * marker.c (byte_char_debug_check, count_markers):
10128 Use only if ENABLE_CHECKING is defined.
10129 (byte_debug_flag): Remove.
10130 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10131 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10133 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10135 Avoid code repetition in marker-related functions.
10136 * marker.c (attach_marker): New function.

10140 Consistently rename charno to charpos.
10141 (marker_position): Add eassert.
10142 (marker_byte_position): Convert to eassert.
10144 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

10158 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10159 (save_restriction_save): Use build_marker.
10160 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10161 * window.c (save_window_save): Likewise.
10163 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10165 Do not use Fdelete_overlay in delete_all_overlays
10166 to avoid redundant calls to unchain_overlay.
10167 * buffer.c (drop_overlay): New function.
10168 (delete_all_overlays, Fdelete_overlay): Use it.
10169 * minibuf.c (get_minibuffer): Fix comment.
10171 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10173 Port to OpenBSD 5.1 amd64.
10174 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10175 This is needed for OpenBSD, and should be harmless on all BSD systems.
10176 Also, include <sys/sysctl.h>, as it should be available on all
10177 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10178 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10179 use p_pid member, not kp_proc.pid.
10181 2012-07-06 Glenn Morris <rgm@gnu.org>
10183 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10185 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10187 More xmalloc and related cleanup.

10196 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10198 Omit needless casts involving void * pointers and allocation.
10199 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10200 as the former is more robust if P's type is changed.
10201 Prefer xzalloc to xmalloc + memset 0.
10202 Simplify malloc-or-realloc to realloc.
10203 Don't worry about xmalloc returning a null pointer.
10204 Prefer xstrdup to xmalloc + strcpy.
10205 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10207 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10208 alloca of a constant.

10212 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10213 hscroll is larger than the line width. Fixes long and futile
10214 looping inside extend_face_to_end_of_line (on a TTY) producing
10215 glyphs that are not needed and thrown away.
10217 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10219 * marker.c (set_marker_restricted_both): Simplify by using
10222 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

10233 followed by gtk_box_set_homogeneous (Bug#11768).
10234 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10235 (update_theme_scrollbar_width, xg_create_scroll_bar):

10238 (is_box_type): New function (Bug#11768).
10239 (xg_tool_item_stale_p): Call is_box_type.
10240 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10241 with default display (Bug#11768).
10243 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10245 * xdisp.c (window_hscroll_limited): New function.
10246 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10247 coordinates when window's hscroll is set to insanely large
10248 values. (Bug#11857)
10250 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10314 Problem reported by Troels Nielsen in
10315 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10317 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10319 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10320 This should be fixed in a better way; see Eli Zaretskii in
10321 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10322 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10324 * fileio.c (time_error_value): Rename from special_mtime.
10325 The old name's problems were noted by Eli Zaretskii in
10326 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10328 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10329 This variable's comment says Emacs needs at least one GDB-visible
10330 symbol of type enum pvec_type, to work around GDB problems.
10331 The symbol's value doesn't matter.
10333 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10334 that causes compilation to fail on pre-C99 compilers.
10336 2012-07-04 Juanma Barranquero <lekktu@gmail.com>

10341 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10343 * buffer.c (init_buffer_once): Fix initialization of
10344 headers for buffer_defaults and buffer_local_symbols.
10345 Reported by Juanma Barranquero <lekktu@gmail.com>.

10363 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10364 abusing vector->header.next.nbytes.
10365 (live_vector_p): Use PVEC_TYPE.
10366 (mark_object): Adapt code to extract pvectype. Use switch.
10368 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10370 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10371 Tighten new eassert a bit.
10373 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10375 Fix compilation with --enable-gcc-warnings and -O1
10376 optimization level.
10377 * doprnt.c (doprnt): Change type of tem to int, initialize
10378 to avoid compiler warning. Add eassert.
10379 * search.c (simple_search): Initialize match_byte to avoid
10380 compiler warning. Add eassert.
10382 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10384 Avoid weird behavior with large horizontal scrolls.
10385 Without this change, for example, large hscroll values would
10386 mess up Emacs's display on Fedora 15 x86, presumably due to
10387 overflows in int calculations in the display code.
10388 Also, if buffers had long lines, Emacs would freeze.
10389 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10390 (set_window_hscroll): New function, containing the old guts of
10391 Fset_window_hscroll. Return the clipped value.
10392 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10393 This avoids the need to check against PTRDIFF_MAX.
10395 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10397 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10399 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10401 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10403 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10404 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10405 since GCC 4.4.6 issues a bogus warning for them.
10407 Fix bugs in file timestamp newness comparisons.
10408 * fileio.c (Ffile_newer_than_file_p):
10409 * lread.c (Fload): Use full timestamp resolution of files,
10410 not just the 1-second resolution, so that files that are only
10411 slightly newer still count as newer.
10412 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10413 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10415 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10417 * fileio.c: Improve handling of file time marker. (Bug#11852)
10418 (special_mtime): New function.
10419 (Finsert_file_contents, Fverify_visited_file_modtime):
10420 Use it to set special mtime values consistently.
10422 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10424 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10425 marker for non-existing file. (Bug#11852)
10427 2012-07-03 Glenn Morris <rgm@gnu.org>
10429 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10430 and did not make it into globals.h).
10432 2012-07-03 Tom Tromey <tromey@redhat.com>
10434 * window.c (Fset_window_margins, Fset_window_fringes)
10435 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10436 * textprop.c (Fprevious_property_change): No longer static.
10437 * syntax.c (Fsyntax_table_p): No longer static.
10438 * process.c (Fget_process, Fprocess_datagram_address): No longer
10440 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
10441 * keyboard.c (Fcommand_execute): No longer static.
10443 * insdel.c (Fcombine_after_change_execute): No longer static.

10460 * fontset.h: Remove EXFUN.
10461 * font.h: Remove EXFUNs.
10462 * dosfns.c (system_process_attributes): Remove EXFUN.
10463 * keymap.h: Remove EXFUNs.
10464 * lisp.h: Remove EXFUNs.
10465 * w32term.h: Remove EXFUNs.
10466 * window.h: Remove EXFUNs.
10467 * xsettings.h: Remove EXFUN.
10468 * xterm.h: Remove EXFUN.
10470 2012-07-03 Glenn Morris <rgm@gnu.org>
10472 * lisp.h (Frandom): Make it visible to C.
10473 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10474 buffer for invisible buffers. (Bug#1229)
10476 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10478 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10479 values which aren't power of 2.
10480 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10481 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10484 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10486 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10488 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10490 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10492 * alloc.c (allocate_vector_block): Remove redundant
10493 calls to mallopt if DOUG_LEA_MALLOC is defined.
10494 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10495 avoid calls to mallopt if zero_vector is returned.
10497 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10499 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10500 is enabled, avoid dereferencing NULL current_sblock if
10503 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10505 Cleanup basic buffer management.
10506 * buffer.h (struct buffer): Change layout to use generic vector
10507 marking code. Fix some comments. Change type of 'clip_changed'
10508 to bitfield. Remove unused #ifndef old.
10509 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10510 (GET_OVERLAYS_AT): Fix indentation.
10511 (for_each_per_buffer_object_at): New macro.
10512 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10513 (Fbuffer_local_variables): Use it.
10514 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
10515 * alloc.c (allocate_buffer): Adjust to match new layout of
10516 struct buffer. Fix comment.
10517 (mark_overlay): New function.
10518 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10519 Lisp area of struct buffer.
10520 (mark_object): Use it. Adjust marking of misc objects
10521 and related comments.
10523 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10525 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10526 wrapper that is not needed because the wrapped code is a no-op (zero
10527 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10528 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10530 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10532 * alloc.c (mark_buffer): Simplify. Remove prototype.
10533 (mark_object): Add comment. Reorganize marking of vector-like
10534 objects. Use CHECK_LIVE for all vector-like objects except buffers
10535 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10536 Avoid redundant calls to mark_vectorlike for bool vectors.
10538 2012-06-30 Glenn Morris <rgm@gnu.org>
10540 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10542 * epaths.in (PATH_SITELOADSEARCH): New.
10543 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10544 This is rather than relying on --enable-locallisppath elements
10545 having "site-lisp" in their names. (Bug#10208#25, 11658)
10547 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10549 * w32proc.c (sys_select): Accept and ignore one more argument.
10551 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10553 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10554 (pselect) [!MS_DOS]: Redirect to sys_select.
10556 * sysdep.c: Don't include dos.h and dosfns.h.
10558 * process.c (sys_select):
10559 * msdos.c (sys_select): Accept one more argument and ignore it.
10561 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10562 adapt data types and code to that.
10565 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10566 which clashes with the gnulib function of the same name.
10568 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10570 * font.c (font_style_to_value, font_style_symbolic)
10571 (font_prop_validate_style): Add type checks for values in
10574 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10576 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10579 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10581 * xdisp.c (try_window_id): Undo last change.
10583 * w32.c (getwd): Adjust commentary about startup_dir.
10584 (init_environment): Always call sys_access, even in non-MSVC
10585 builds. Don't chdir to the directory of the Emacs executable.
10586 This undoes code from 1997 which was justified by the need to
10587 "avoid conflicts when removing and renaming directories". But its
10588 downside was that every relative file name was being interpreted
10589 relative to the directory of the Emacs executable, which can never
10590 be TRT. In particular, it broke sys_access when called with
10591 relative file names.
10592 (sys_access): Map GetLastError to errno.
10594 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10596 * window.h (struct window): Change type of 'fringes_outside_margins'
10597 to bitfield. Fix comment. Adjust users accordingly.
10598 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10600 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10603 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10605 * gnutls.c (emacs_gnutls_handshake):
10606 Add QUIT to make the loop interruptible.
10608 2012-06-29 Glenn Morris <rgm@gnu.org>
10610 * charset.c (init_charset): Make lack of etc/charsets fatal.
10612 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10614 * editfns.c (region_limit): Fix type mismatch.
10616 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10618 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10619 undefined. Convert from xassert to eassert.
10620 * nsmenu.m: Convert from xassert to eassert.
10621 * nsterm.m: Likewise.
10623 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
10625 * editfns.c (region_limit): Clip to narrowing (bug#11770).
10627 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10629 Avoid integer overflow on scroll-left and scroll-right.
10630 * window.c (HSCROLL_MAX): New macro.
10631 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10632 overflow when requested scroll falls outside ptrdiff_t range.
10634 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10636 * window.h (struct window): Change type of 'hscroll',
10637 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10638 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10639 Adjust users accordingly.
10640 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10641 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10642 from EMACS_INT to ptrdiff_t.
10643 (make_window): Omit redundant initialization.

10661 enabled with --enable-checking=[all,glyphs] configure option.
10662 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10663 adjust comments accordingly.

10712 * alloc.c (allocate_string_data): Remove dead code.
10713 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to

10718 * alloc.c (allocate_string): Omit intervals initialization.

10744 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
10745 when building with Clang.

10776 * alloc.c: Remove build_string.

10784 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
10786 Use sprintf return value instead of invoking strlen on result.
10787 In the old days this wasn't portable, since some sprintf
10788 implementations returned char *. But they died out years ago and
10789 Emacs already assumes sprintf returns int.
10790 Similarly for float_to_string.
10791 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
10792 * ccl.c (ccl_driver):
10793 * character.c (string_escape_byte8):

10796 * print.c (print_object):
10797 * xdisp.c (message_dolog):
10798 * xfns.c (syms_of_xfns):
10799 Use sprintf or float_to_string result to avoid need to call strlen.
10800 * data.c (Fnumber_to_string):
10801 Use make_unibyte_string, since the string must be ASCII.
10802 * lisp.h, print.c (float_to_string): Now returns int length.
10803 * term.c (produce_glyphless_glyph):
10804 Use sprintf result rather than recomputing it.
10806 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
10807 * Makefile.in (ALL_CFLAGS):
10808 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

10813 * dispextern.h (xstrcasecmp): Define to library function
10814 strcasecmp if available.

10833 sprintf already null-terminates its output.
10835 * xfns.c (x_window): Remove redundant cast.
10837 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10839 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10840 `const char *' to `char *' to avoid compiler warning.
10842 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10844 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10845 instead of truncating it to 63 (admittedly a generous limit).
10847 * process.c: Fix spelling and caps in comments.
10849 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10851 * emacs.c (setpgrp): Remove definition, unused.

10860 * makefile.w32-in (TIMESPEC_H): Remove nt/inc/sys/time.h.
10861 (SYSTIME_H): Add nt/inc/sys/time.h.
10863 * systime.h [WINDOWSNT]: Include sys/time.h.
10865 * s/ms-w32.h (struct timespec): Definition moved from

10902 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
10903 * lisp.h (WAIT_READING_MAX): New macro.
10904 * dispnew.c (Fsleep_for, sit_for):
10905 * keyboard.c (kbd_buffer_get_event):
10906 * process.c (Faccept_process_output):
10907 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10908 This improves on the previous patch, which introduced a bug
10909 when time_t is unsigned and as wide as intmax_t.
10910 See <http://bugs.gnu.org/9000#51>.
10912 2012-06-23 Eli Zaretskii <eliz@gnu.org>

10941 language ID in the event parameters.
10943 * w32term.c (w32_read_socket): Put the new keyboard codepage into
10944 event.code, not the obscure "character set ID".
10946 2012-06-23 Chong Yidong <cyd@gnu.org>

10975 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10977 Support higher-resolution time stamps (Bug#9000).
10978 The time stamps are only nanosecond-resolution at the C level,
10979 since that's the best that any real-world system supports now.
10980 But they are picosecond-resolution at the Lisp level, as that's
10981 easy, and leaves room for future OS improvements.
10983 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10986 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10987 Don't get current time unless it's needed.
10989 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10990 now provides it if it's absent.
10991 (start_atimer): Port to higher-res time stamps.
10992 Check for time stamp overflow. Don't get current time more
10993 often than is needed.
10995 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10996 Include systime.h, not time.h.
10997 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10999 * dired.c: Include stat-time.h.
11000 (Ffile-attributes): File times now have higher resolution.
11002 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11003 (struct image): Timestamp now has higher resolution.
11005 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11006 has at least microseconds now. All uses removed.
11007 (update_frame, update_single_window, update_window, update_frame_1)
11008 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11009 (duration_to_sec_usec): Remove; no longer needed.
11011 * editfns.c (time_overflow): Now extern.
11012 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

11017 (decode_time_components, lisp_seconds_argument): New functions.
11018 (make_time): Now static.
11019 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11020 Report an error if the time is invalid, rather than having the caller
11023 * fileio.c: Include <stat-time.h>
11024 (Fcopy_file): Copy higher-resolution time stamps.
11025 Prefer to set the time stamp via a file descriptor if that works.
11026 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11027 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11028 (Fvisited_file_modtime, Fset_visited_file_modtime):
11029 Support higher-resolution time stamps.
11031 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11033 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11035 * image.c (prepare_image_for_display, clear_image_cache)
11036 (lookup_image): Port to higer-resolution time stamps.
11038 * keyboard.c (start_polling, bind_polling_period):
11039 Check for time stamp overflow.
11040 (read_char, kbd_buffer_get_event, timer_start_idle)
11041 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11042 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11043 Port to higher-resolution time stamps. Do not assume time_t is signed.
11044 (decode_timer): New function. Timers are now vectors of length 9,
11045 not 8, to accommodate the picosecond component.
11046 (timer_check_2): Use it.
11048 * nsterm.m (select_timeout, timeval_subtract): Remove.
11049 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11050 as they're a bit more accurate and handle overflow better.
11051 (ns_select): Change prototype to be compatible with pselect.
11052 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11053 * nsterm.h (ns_select): Adjust prototype.
11055 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11056 us-resolution time stamps.
11057 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11059 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11061 * lisp.h (time_overflow): New decl.
11062 (wait_reading_process_output): First arg is now intmax_t, not int,
11063 to accommodate larger waits.
11065 * process.h (struct Lisp_Process.read_output_delay):
11066 Now counts nanoseconds, not microseconds.
11067 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11069 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11070 (wait_reading_process_output):
11071 Port to ns-resolution time stamps.
11072 (Faccept_process_output, wait_reading_process_output):
11073 Check for time stamp overflow. Do not assume time_t is signed.
11074 (select_wrapper): Remove; we now use pselect.
11075 (Fprocess_attributes): Now generates ns-resolution time stamps.
11077 * sysdep.c: Include utimens.h. Don't include utime.h
11078 or worry about struct utimbuf; gnulib does that for us now.
11079 (gettimeofday): Remove; gnulib provides a substitute.
11080 (make_timeval): New function.
11081 (set_file_times): Now sets ns-resolution time stamps.
11082 New arg FD; all uses changed.
11083 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11084 (system_process_attributes):
11085 Now returns ns-resolution time stamp. All uses changed.
11086 Check for time stamp overflow.
11088 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11089 provides a substitute now.
11091 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11092 since it guarantees struct timespec.
11093 (EMACS_TIME): Now struct timespec, so that we can support
11094 ns-resolution time stamps.
11095 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11096 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11097 (EMACS_USECS): Remove.
11098 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11099 so multiply the arg by 1000 before storing it.
11100 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11102 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11103 Port to ns-resolution time stamps.
11104 (EMACS_TIME_NEG_P): Remove; replaced by....

11107 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
11108 (set_file_times, make_time, lisp_time_argument): Adjust signature.
11109 (make_timeval, make_lisp_time, decode_time_components): New decls.
11110 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11111 that it mishandled time_t overflow. You can't compare by subtracting!
11112 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11113 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11115 * term.c: Include <sys/time.h>.
11116 (timeval_to_Time): New function, for proper overflow wraparound.
11117 (term_mouse_position, term_mouse_click): Use it.
11119 * undo.c (record_first_change): Support higher-resolution time stamps
11120 in the undo buffer.
11121 (Fprimitive_undo): Use them when restoring time stamps.
11123 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11124 (w32_get_internal_run_time):
11125 Port to higher-resolution Emacs time stamps.
11126 (ltime): Now accepts single 64-bit integer, as that's more convenient
11129 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11131 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11132 for compatibility with pselect. Support ns-resolution time stamps.
11134 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11136 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11137 Check for time stamp overflow, and support ns-resolution time stamps.
11139 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11140 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11141 (timeval_subtract): Remove; no longer needed.
11142 (XTflash, XTring_bell, x_wait_for_event):
11143 Port to ns-resolution time stamps. Don't assume time_t is signed.
11145 2012-06-22 Chong Yidong <cyd@gnu.org>

11149 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11151 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11152 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11153 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11154 staticidx goes up to 1597 out of 1600 = 0x640.)
11156 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11158 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
11159 Otherwise, the umask might be mistakenly 0 while handling input signals.
11161 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

11170 access to `contents' member of Lisp_Vector objects with AREF and ASET
11173 2012-06-19 Chong Yidong <cyd@gnu.org>
11175 * frame.c (delete_frame): When selecting a frame on a different
11176 text terminal, do not alter the terminal's top-frame.

11179 frame's selected window and its terminal's top-frame.
11180 (unwind_format_mode_line): Restore them.
11181 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11183 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11184 since tty frames can be explicitly named.
11185 (prepare_menu_bars): Likewise.
11187 * term.c (Ftty_top_frame): New function.
11189 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

11192 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11193 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11194 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11195 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
11196 (METER_1, METER_2): Simplify.
11198 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

11202 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11204 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11205 gets killed during executing of this function (Bug#11665).
11206 Try to always return Qt when the buffer has been actually killed.
11207 (Vkill_buffer_query_functions): In doc-string say that functions
11208 run by this hook should not change the current buffer.
11210 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11212 Fix recently-introduced process.c problems found by static checking.
11213 * process.c (write_queue_push, write_queue_pop, send_process):
11214 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
11215 (write_queue_pop): Fix pointer signedness problem.
11216 (send_process): Remove unused local.
11218 2012-06-17 Chong Yidong <cyd@gnu.org>

11232 * lisp.h (eassert): Assume C89 or later.
11233 This removes the need for CHECK.
11234 (CHECK): Remove. Its comments about always evaluating its
11235 argument were confusing, as 'eassert' typically does not evaluate
11238 * coding.c (produce_chars): Use ptrdiff_t, not int.
11240 * xterm.c (x_draw_underwave): Check for integer overflow.
11241 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

11245 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
11246 referenced (Bug#11583).

11339 indexing into it->string_overlays array. (Bug#11653)
11340 (set_cursor_from_row): Use the leftmost glyph as GLYPH_BEFORE, not

11363 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
11364 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):

11415 * alloc.c (make_number) [!defined make_number]:
11416 Remove, as lisp.h always defines this now.

11427 as the union type is for debugging, not for production.
11428 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
11429 Use an inline function on all platforms when using the union type,
11430 since this is simpler and 'static inline' can be used portably

11433 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
11434 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

11537 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
11539 2012-06-08 Eli Zaretskii <eliz@gnu.org>

11574 * doprnt.c (doprnt): Truncate multibyte char correctly.
11575 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11576 would mishandle a string argument "Xc" if X was a multibyte
11577 character of length 2: it would truncate after X's first byte
11578 rather than including all of X.
11580 2012-06-06 Chong Yidong <cyd@gnu.org>
11582 * buffer.c (word_wrap): Doc fix.

11629 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11631 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11632 Convert pctcpu and pctmem to Lisp float properly.
11633 Let the compiler fold better, as 100.0/0x8000 is exact.

11637 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

11649 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11650 change its type from Lisp_Object to bitfield.
11651 Change type of 'force_start', 'optional_new_start',
11652 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

11659 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11660 Use 'float' consistently, rather than 'float' in most places
11661 and 'double' in a couple of places.
11663 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11665 * xdisp.c (handle_stop): Detect whether we have overlay strings
11666 loaded by testing it->current.overlay_string_index to be
11667 non-negative, instead of checking whether n_overlay_strings is
11668 positive. (Bug#11587)
11670 2012-05-31 Chong Yidong <cyd@gnu.org>
11672 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11678 * search.c (search_buffer): Remove calls to
11679 r_alloc_inhibit_buffer_relocation, as it is now called by

11685 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11686 for the duration of call to load_charset, to avoid problems with
11687 callers of maybe_unify_char that access buffer text through C
11690 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11691 decrement the inhibition flag, instead of just setting or
11694 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11696 Remove obsolete '#define static' cruft.
11697 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11698 This #undef was "temporary" in 2000; it is no longer needed

11714 (safe_bcopy): Remove decl; no longer has that name.
11715 (main): Coalesce #if into single bit of code, for simplicity.

11746 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11747 Bug#9642, but explicitly check that the buffer the overlay would
11748 be moved to is live and rearrange lines to make sure that errors
11749 will not put the overlay in an inconsistent state.
11750 (Fdelete_overlay): Cosmetics.
11752 2012-05-28 Eli Zaretskii <eliz@gnu.org>

11766 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11768 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11769 This avoids undefined behavior that might cause the eassert
11770 to not catch an out-of-range value.
11772 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11774 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11775 Update dependencies.
11777 2012-05-27 Eli Zaretskii <eliz@gnu.org>

11784 when referring to sectname field in printf format.
11786 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11788 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11789 Only r_alloc_inhibit_buffer_relocation needed to be added;
11790 the others were already declared.
11792 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11793 before checking whether it's out of range. Put the check inside
11795 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11797 2012-05-27 Ken Brown <kbrown@cornell.edu>
11799 * callproc.c (Fcall_process): Restore a line that was accidentally
11800 commented out in the 2011-02-13 change (bug#11547).
11802 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11804 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11805 defined on ralloc.c.
11807 * buffer.c [REL_ALLOC]: Remove prototypes of
11808 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11809 they are now on lisp.h.
11811 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11813 * search.c (search_buffer): Use it to inhibit relocation of buffer
11814 text while re_search_2 is doing its job, because re_search_2 is
11815 passed C pointers to buffer text. (Bug#11519)
11817 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11818 Update value to 24.
11820 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11821 state after an additional call to move_it_in_display_line_to, keep
11822 the values of it->max_ascent and it->max_descent found for the
11824 (pos_visible_p): Revert the comparison against bottom_y to what it
11825 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11828 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11830 Fix coding-related core dumps with gcc -ftrapv.
11831 The code was computing A - B, where A and B are pointers, and B is
11832 random garbage. This can lead to core dumps on platforms that
11833 have special pointer registers, and it also leads to core dumps on
11834 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11835 A - B only when B is initialized properly.
11836 * coding.c (coding_set_source, coding_set_destination): Return void.
11837 (coding_change_source, coding_change_destinations): New functions,
11838 with the old behaviors of coding_set_source and coding_set_destination.
11839 All callers that need an offset changed to use these new functions.
11841 2012-05-26 Glenn Morris <rgm@gnu.org>
11843 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
11845 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11847 Extend mouse support on W32 text-mode console.
11848 * xdisp.c (draw_row_with_mouse_face):
11849 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
11851 * w32console.c: Include window.h.
11852 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
11854 (initialize_w32_display): Initialize mouse-highlight data.
11856 * w32inevt.c: Include termchar.h and window.h.
11857 (do_mouse_event): Support mouse-autoselect-window. When the mouse
11858 moves, call note_mouse_highlight. If help_echo changed, call
11859 gen_help_event to produce help-echo message in the echo area.
11860 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11863 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11865 * lread.c (read1): Simplify slightly to avoid an overflow warning
11866 with GCC 4.7.0 on x86-64.
11868 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11870 * bidi.c (bidi_mirror_char): Revert last change: an int is
11871 definitely wide enough here.
11873 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
11875 Fix integer width and related bugs (Bug#9874).

11885 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11886 (allocate_pseudovector):
11887 Use int, not EMACS_INT, where int is wide enough.
11888 (inhibit_garbage_collection, Fgarbage_collect):
11889 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11890 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11891 int might not be wide enough.
11892 (bidi_cache_search, bidi_cache_find, bidi_init_it)

11907 (Foverlay_recenter, last_overlay_modification_hooks_used)
11908 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11909 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11910 (validate_region): Omit unnecessary test for b <= e,
11911 since that's guaranteed by the previous test.
11912 (adjust_overlays_for_delete): Avoid pos + length overflow.
11913 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11914 (report_overlay_modification):
11915 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11916 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11917 Omit pointer cast, which isn't needed anyway, and doesn't work
11918 after the EMACS_INT -> ptrdiff_t change.
11919 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11920 * buffer.h: Adjust decls to match defn changes elsewhere.
11921 (struct buffer_text, struct buffer):
11922 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11923 Use EMACS_INT, not int, where int might not be wide enough.
11924 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
11925 not int, to avoid needless 32-bit limit on 64-bit hosts.
11926 (exec_byte_code): Use tighter memory-full test, one that checks
11927 for alloca overflow. Don't compute the address of the object just
11928 before an array, as that's not portable. Use EMACS_INT, not
11929 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11930 * callint.c (Fcall_interactively):
11931 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11932 * callproc.c (call_process_kill, Fcall_process):
11933 Don't assume pid_t fits into an Emacs fixnum.
11934 (call_process_cleanup, Fcall_process, child_setup):

11942 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
11943 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11944 (casify_object): Avoid integer overflow when overallocating buffer.
11945 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11946 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
11947 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
11948 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11949 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11950 integers are now checked earlier. All uses replaced with XINT.
11952 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11953 For CCL_MapSingle, check that content and value are in int range.
11954 (ccl_driver, Fregister_code_conversion_map):
11955 Check that Vcode_version_map_vector is a vector.
11956 (resolve_symbol_ccl_program): Check that vector header is in range.
11957 Always copy the vector, so that we can check its contents reliably
11958 now rather than having to recheck each instruction as it's being
11959 executed. Check that vector words fit in 'int'.
11960 (ccl_get_compiled_code, Fregister_ccl_program)
11961 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11962 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11963 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11964 contents are in range.
11965 (Fccl_execute_on_string): Check that status is in range.
11966 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11967 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11968 Accept and return EMACS_INT, not int, because callers can pass values
11969 out of 'int' range.

11971 (multibyte_chars_in_text, parse_str_as_multibyte)

11975 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11976 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11977 avoid mishandling large integers.
11978 * character.h: Adjust decls to match defn changes elsewhere.
11979 * charset.c (load_charset_map_from_file, find_charsets_in_text)

11984 Don't assume fixnum fits in int.
11985 (load_charset_map_from_vector, Fmap_charset_chars):
11986 Remove now-unnecessary CHECK_NATNUMs.
11987 (Fdefine_charset_internal): Check ranges here, more carefully.
11988 Don't rely on undefined behavior with signed left shift overflow.
11989 Don't assume unsigned int fits into fixnum, or that fixnum fits
11990 into unsigned int. Don't require max_code to be a valid fixnum;
11991 that's not true for gb10830 4-byte on a 32-bit host. Allow
11992 invalid_code to be a cons, for the same reason. Require code_offset
11993 to be a character. Avoid int overflow if max_char is close
11995 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11996 this is intended anyway and avoids some undefined behavior.
11997 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11998 INDEX_TO_CODE_POINT, as that's what it expects.
11999 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12000 * charset.h (DECODE_CHAR): Return int, not unsigned;
12001 this is what was intended anyway, and it avoids undefined behavior.
12002 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12003 integer-overflow issues.
12004 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12005 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12006 where the argument is EMACS_INT, and this behavior is not intended.
12007 * chartab.c (Fmake_char_table, Fset_char_table_range)
12008 (uniprop_get_decoder, uniprop_get_encoder):
12009 Don't assume fixnum fits in int.
12010 * cmds.c (move_point): New function, that does the gist of
12011 Fforward_char and Fbackward_char, but does so while checking
12012 for integer overflow more accurately.
12013 (Fforward_char, Fbackward_char): Use it.
12014 (Fforward_line, Fend_of_line, internal_self_insert)
12015 (internal_self_insert):
12016 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12075 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
12076 Do not attempt to compute the address of the object just before a

12824 (set_iterator_to_next): If called at the end of a Lisp string,
12825 proceed to consider_string_end without incrementing string
12826 position. Don't increment display vector index past the end of
12827 the display vector. (Bug#11417)
12828 (pos_visible_p): Don't report a position visible when move_it_to
12829 stopped at the last line of window, which happens to be scanned
12830 backwards by the bidi iteration. (Bug#11464)
12832 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12834 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12835 and right-margin display specs even if the spec is invalid or we
12836 are on a TTY, and thus unable to display on the fringes.
12837 That's because the text with the property will not be displayed anyway,
12838 so we need to signal to the caller that this is a "replacing"
12839 display spec. This fixes display when the spec is invalid or we
12842 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12844 * unexaix.c (make_hdr): Fix typo in prototype.
12845 This bug broke the build on AIX. Problem reported by Gilles Pion.
12847 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12849 * keyboard.c (kbd_buffer_get_event): Read special events also in
12850 batch mode. (Bug#11415)
12852 2012-05-12 Glenn Morris <rgm@gnu.org>
12854 * ns.mk: Update for ns_appbindir no longer having trailing "/".
12856 2012-05-12 Eli Zaretskii <eliz@gnu.org>
12858 * lisp.mk (lisp): Add newcomment.elc.
12860 2012-05-12 Glenn Morris <rgm@gnu.org>
12862 * Makefile.in (MKDIR_P): New, set by configure.
12863 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12865 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
12867 Remove unused function hourglass_started.
12868 * dispextern.h (hourglass_started):
12869 * w32fns.c (hourglass_started):
12870 * xdisp.c (hourglass_started): Remove.
12872 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
12874 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
12875 Update dependencies.
12877 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12879 * xgselect.c (xg_select): Put maxfds+1 into a var.
12880 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12882 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12884 2012-05-10 Dave Abrahams <dave@boostpro.com>
12886 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12887 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12889 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12891 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12892 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12893 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12894 Initialize xd_registered_buses.
12896 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12898 Untag more efficiently if USE_LSB_TAG.
12899 This is based on a proposal by YAMAMOTO Mitsuharu in
12900 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12901 For an admittedly artificial (nth 8000 longlist) benchmark on
12902 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12903 Emacs's overall text size by 1%.
12904 * lisp.h (XUNTAG): New macro.
12905 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12906 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12907 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12908 * eval.c (Fautoload):
12909 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12910 * frame.h (XFRAME): Use XUNTAG.
12912 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12913 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12914 Remove unportable assumptions about print widths of types like
12916 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12917 intptr_t when converting between pointer and integer, to avoid GCC
12918 warnings about wrong width.
12920 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12922 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12923 stack for each reader_thread, instead of defaulting to 8MB
12924 determined by the linker. This avoids failures in creating
12925 subprocesses on Windows 7, see the discussion in this thread:
12926 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12928 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12930 Fix up display of the *Minibuf-0* buffer in the mini window.
12931 * keyboard.c (read_char): Don't clear the echo area if there's no
12933 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12934 contents of *Minibuf-0*) if there's no message displayed in its stead.
12936 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12938 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12941 2012-05-06 Chong Yidong <cyd@gnu.org>
12943 * lisp.mk (lisp): Update.
12945 2012-05-05 Jim Meyering <meyering@redhat.com>
12947 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12949 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12951 * data.c (PUT_ERROR): New macro.
12952 (syms_of_data): Use it. Add new error type `user-error'.
12953 * undo.c (user_error): New function.
12954 (Fprimitive_undo): Use it.
12955 * print.c (print_error_message): Adjust print style for `user-error'.
12956 * keyboard.c (user_error): New function.
12957 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12959 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12961 Do not limit current-time-string to years 1000..9999.
12962 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12963 (Fcurrent_time_string): Support any year that is supported by the
12964 underlying localtime representation. Don't use asctime, as it
12965 has undefined behavior for years outside the range -999..9999.
12967 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12969 Fix race conditions involving setenv, gmtime, localtime, asctime.
12970 Without this fix, interrupts could mess up code that uses these
12971 nonreentrant functions, since setting TZ invalidates existing
12972 tm_zone or tzname values, and since most of these functions return
12973 pointers to static storage.
12974 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12975 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12976 Grow the critical sections to include not just invoking
12977 localtime/gmtime, but also accessing these functions' results
12978 including their tm_zone values if any, and any related TZ setting.
12979 (format_time_string): Last arg is now struct tm *, not struct tm **,
12980 so that the struct tm is saved in the critical section.
12981 All callers changed. Simplify allocation of initial buffer, partly
12982 motivated by the fact that memory allocation needs to be outside
12983 the critical section.
12985 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12987 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12988 with RESET_INTERVAL.
12990 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12991 Remove duplicated buffer name initialization.
12993 2012-05-02 Jim Meyering <jim@meyering.net>
12995 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12997 * xfns.c (x_window): Use xstrdup (Bug#11375).
12999 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13001 * xdisp.c (pos_visible_p): If already at a newline from the
13002 display string before the 'while' loop, don't walk back the glyphs
13003 from it3.glyph_row. Solves assertion violation when the display
13004 string begins with a newline (egg.el). (Bug#11367)
13006 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13008 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13011 2012-05-01 Glenn Morris <rgm@gnu.org>
13013 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13014 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13015 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13016 All were removed before 23.1.
13018 * dispnew.c: Remove HAVE_LIBNCURSES test;
13019 it is always true on relevant platforms.
13021 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13022 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13024 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13026 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13028 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13029 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13032 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13034 Do not avoid creating empty evaporating overlays (Bug#9642).
13035 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13036 That is, do not delete an evaporating overlay if it becomes
13037 empty after its bounds are adjusted to fit within its buffer.
13038 This fix caused other problems, and I'm reverting it until we get
13039 to the bottom of them.
13041 2012-04-27 Chong Yidong <cyd@gnu.org>
13043 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13045 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13047 * xdisp.c (pos_visible_p): If the window start position is beyond
13048 ZV, start the display from buffer beginning. Prevents assertion
13049 violation in init_iterator when the minibuffer window is scrolled
13050 via the scroll bar.
13052 * window.c (window_scroll_pixel_based): Likewise.
13054 2012-04-27 Chong Yidong <cyd@gnu.org>
13056 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13058 2012-04-27 Glenn Morris <rgm@gnu.org>
13060 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13061 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13063 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13065 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13066 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13068 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13070 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13071 display element, check also the underlying string or buffer
13072 character. (Bug#11341)
13074 * w32menu.c: Include w32heap.h.
13075 (add_menu_item): If the call to AppendMenuW (via
13076 unicode_append_menu) fails, disable Unicode menus only if we are
13077 running on Windows 9X/Me.
13079 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13081 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13082 (xgetint): Add missing shift for LSB tags.
13084 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13086 * keyboard.c (read_char): Don't wipe echo area for select window
13087 events: These might get delayed via `mouse-autoselect-window'
13090 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13092 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13093 manipulation of :loaded-from data.
13095 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13097 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13098 now a cons (bug#11311).
13100 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13102 Do not create empty overlays with the evaporate property (Bug#9642).
13103 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13104 if it becomes empty after its bounds are adjusted to fit within
13105 its buffer. Without this fix, in a nonempty buffer (let ((o
13106 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13107 yields an empty overlay that has the evaporate property, which is
13108 not supposed to happen.
13110 Fix minor GTK3 problems found by static checking.
13111 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13112 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13113 (struct _EmacsFixedClass, emacs_fixed_get_type):
13114 Move decls here from emacsgtkfixed.h, since they needn't be public.
13115 (emacs_fixed_get_type): Now static.
13116 (emacs_fixed_class_init): Omit unused local.
13117 (emacs_fixed_child_type): Remove; unused.
13118 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13119 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13120 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13121 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
13122 (EMACS_FIXED_GET_CLASS): Remove; unused.
13123 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
13125 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
13126 Problem reported by Juanma Barranquero for Windows -Wunused-function.
13128 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13130 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13131 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13132 (__malloc_size_t, __malloc_ptrdiff_t):
13133 Remove. All uses removed, replaced by the definiens if needed,
13134 since we can assume C89 or better now.
13135 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
13136 (protect_malloc_state, align, get_contiguous_space)
13137 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

13141 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
13142 (special_realloc, _realloc_internal_nolock, _realloc_internal)
13143 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13144 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13145 Define using prototypes, not old style.
13146 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
13147 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
13148 (align): Don't assume that signed integer overflow wraps around.
13149 Omit unused local var.
13150 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

13152 Omit no-longer-needed casts.
13153 (valloc): Use getpagesize, not __getpagesize.
13154 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
13155 (struct hdr): The 'magic' member is now size_t, not unsigned long.
13157 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
13159 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
13161 Move functions from C to Lisp. Make non-blocking method calls
13162 the default. Implement further D-Bus standard interfaces.

13182 (xd_get_connection_address): Rename from xd_initialize.
13183 Return cached address.
13184 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.

13189 (Fdbus_get_unique_name): Make stronger parameter check.
13190 (Fdbus_message_internal): New defun.
13191 (Fdbus_call_method, Fdbus_call_method_asynchronously)
13192 (Fdbus_method_return_internal, Fdbus_method_error_internal)
13193 (Fdbus_send_signal, Fdbus_register_service)
13194 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

13206 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
13207 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
13208 Do not assume ptrdiff_t is the same width as 'int'.
13210 * alloc.c: Handle unusual debugging option combinations.
13211 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
13212 since the two debugging options are incompatible.
13213 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
13215 (mem_init, mem_insert, mem_insert_fixup):
13216 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
13217 (NEED_MEM_INSERT): Remove; no longer needed.
13219 2012-04-22 Leo Liu <sdl.web@gmail.com>

13223 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13225 * sysdep.c [__FreeBSD__]: Minor cleanups.
13226 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13227 Use Emacs indenting style more consistently. Avoid some casts.
13228 Use 'double' consistently rather than mixing 'float' and 'double'.
13230 2012-04-21 Eduard Wiebe <usenet@pusto.de>
13232 * sysdep.c (list_system_processes, system_process_attributes):

13242 It is never used otherwise.
13244 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13246 * print.c (print_preprocess): Only check print_depth if print-circle
13248 (print_object): Check for cycles even when print-circle is nil and

13267 row, return zero immediately.
13268 (try_cursor_movement): If inside continuation line, don't back up
13269 farther than the first row after the header line, if any.
13270 Don't consider the header-line row as "partially visible", even if
13271 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
13273 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13275 * lread.c (lisp_file_lexically_bound_p): Fix hang at ";-*-\n"

13282 * Makefile.in (C_WARNINGS_SWITCH): Remove.
13283 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
13284 (ALL_CFLAGS): Use new macros rather than old.
13285 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
13286 * regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore
13287 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
13288 -Wunused-result, -Wunused-variable. This should go away once
13289 the Emacs and Gnulib regex code is merged.
13290 (xmalloc, xrealloc): Now static.
13292 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

13309 New extern decls, to avoid calling undeclared functions.
13310 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13311 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13312 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13313 (NEED_MEM_INSERT): New macro.
13314 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13315 Remove one incorrect comment and fix another.
13317 Fix minor ralloc.c problems found by static checking.
13318 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

13323 Improve ralloc.c interface checking.
13324 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
13325 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
13326 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
13327 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)

13329 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
13330 Remove decls. This fixes an "It stinks!".
13332 * alloc.c (which_symbols): Fix alignment issue / type clash.
13334 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13336 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
13337 (struct Lisp_Misc_Any): Likewise.
13338 (struct Lisp_Free): Likewise.
13339 * alloc.c (union aligned_Lisp_Symbol): Define.

13347 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
13349 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
13350 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
13351 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13352 * s/netbsd.h, s/sol2-6.h:
13353 Remove definition of GC_MARK_STACK, since the default now works.
13354 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13355 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
13356 no longer the default.
13357 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13359 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13361 * lread.c (lisp_file_lexically_bound_p):
13362 Fix hang at ";-*-\n" (bug#11238).
13364 2012-04-14 Eli Zaretskii <eliz@gnu.org>
13366 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
13367 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

13376 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
13378 2012-04-13 Reuben Thomas <rrt@sc3d.org>
13380 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
13382 2012-04-11 Daniel Colascione <dancol@dancol.org>
13384 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13385 against is gone. It's better to use vfork now so that when Cygwin
13386 gains a new, working vfork, we use it automatically (bug#10398).
13388 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
13390 * window.c (save_window_save): Obey window-point-insertion-type.

13404 (handle_interrupt): Use it.
13406 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
13408 * w32.c (w32_delayed_load): Record the full path of the library
13409 being loaded (bug#10424).
13411 2012-04-09 Glenn Morris <rgm@gnu.org>
13413 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13414 not just in the obarray, before snarfing them. (Bug#11036)
13416 * Makefile.in ($(leimdir)/leim-list.el):
13417 Pass EMACS rather than BUILT_EMACS.
13419 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
13421 * process.c (make_process):
13422 * process.h: Add integer `gnutls_handshakes_tried' member to
13425 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.

13428 * gnutls.c (gnutls_log_function2i): Convenience log function.
13429 (emacs_gnutls_read): Use new log functions,
13430 `gnutls_handshakes_tried' process member, and
13431 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13432 attempts per process (connection).
13434 2012-04-09 Chong Yidong <cyd@gnu.org>
13436 * eval.c (Fuser_variable_p, user_variable_p_eh)
13437 (lisp_indirect_variable): Functions deleted.
13438 (Fdefvar): Caller changed.
13440 * callint.c (Finteractive, Fcall_interactively):
13441 * minibuf.c (Fread_variable): Callers changed.
13443 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13445 * xdisp.c (set_cursor_from_row): If the display string appears in
13446 the buffer at position that is closer to point than the position
13447 after the display string, display the cursor on the first glyph of
13448 the display string. Fixes cursor display when a 'display' text
13449 property immediately follows invisible text. (Bug#11094)
13451 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13453 composite.c: use 'double' consistently
13454 * composite.c (get_composition_id): Use 'double' consistently
13455 instead of converting 'float' to 'double' and vice versa; this is
13456 easier to understand and avoids a GCC warning.
13458 2012-04-09 Glenn Morris <rgm@gnu.org>
13460 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13461 preparation for dumping it with emacs. (Bug#4789)
13462 (leimdir): New variable.
13463 ($(leimdir)/leim-list.el): New rule.
13464 (emacs$(EXEEXT)): Depend on leim-list.el.

13482 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
13483 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13484 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13485 objects, as mark_maybe_pointer will catch them otherwise.
13486 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13487 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

13496 Support building on MS-Windows with libxml2.
13498 * makefile.w32-in (OBJ2): Add xml.$(O).
13499 (GLOBAL_SOURCES): Add xml.c.
13500 ($(BLD)/xml.$(O)): New dependency list.
13502 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
13503 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13504 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13505 [!WINDOWSNT]: New macros.
13506 (init_libxml2_functions, libxml2_loaded_p): New functions.
13507 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13508 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13509 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13510 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13512 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13513 Call init_libxml2_functions before calling libxml2 functions.
13514 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13516 * emacs.c: Don't include libxml/parser.h.
13517 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13518 xmlCleanupParser directly.
13520 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13522 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13524 * indent.c (Fvertical_motion): If there is a display string at
13525 point, use it.vpos to compute how many lines to backtrack after
13526 move_it_to point. (Bug#11133)
13528 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13530 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13531 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13532 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13533 macros related to unification of CJK characters. For the details,
13534 see the discussion following the message here:
13535 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13537 2012-04-04 Chong Yidong <cyd@gnu.org>
13539 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13541 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13543 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13544 instead of alloca. (Bug#11138)
13546 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13548 * w32menu.c (is_simple_dialog): Properly check lisp types.
13551 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13553 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13554 position we get to after a call to move_it_to fails the
13555 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13556 only if we wind up in a string from display property. (Bug#11063)
13558 * window.c (Fdelete_other_windows_internal): Invalidate the row
13559 and column information about mouse highlight, so that redisplay
13560 restores it after reallocating the glyph matrices. (Bug#7464)
13562 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13563 string comes from a `display' text property, use the buffer
13564 position of that property as if we actually saw that position in
13566 (move_it_by_lines): Remove the assertion that
13567 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13568 violated when there's a before-string at the beginning of a line.
13571 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13573 * xdisp.c (append_space_for_newline): If the default face was
13574 remapped, use the remapped face for the appended newline.
13575 (extend_face_to_end_of_line): Use the remapped default face for
13576 extending the face to the end of the line.
13577 (display_line): Call extend_face_to_end_of_line when the default
13578 face was remapped. (Bug#11068)
13580 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13582 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13584 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

13600 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13601 (command_loop_1): Use it; inhibit selection update for
13602 handle-select-window too (Bug#8996).

13606 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13608 2012-03-25 Kenichi Handa <handa@m17n.org>
13610 * dispextern.h (struct glyph): Change the bit length of
13611 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13613 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13615 * s/ms-w32.h (tzname): Include time.h before redirecting to

13620 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13623 * xterm.c (XTread_socket): Only modify handling_signal if
13624 !SYNC_INPUT. (Bug#11080)
13626 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13628 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13629 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13630 when fetching a multibyte character consumes more bytes than
13631 CHAR_BYTES returns, due to unification of CJK characters in
13632 string_char. (Bug#11073)
13634 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13636 * process.c (wait_reading_process_output): Handle pty disconnect
13637 by refraining from sending oneself a SIGCHLD (bug#10933).
13639 2012-03-22 Chong Yidong <cyd@gnu.org>
13641 * dispextern.h (struct it): New member string_from_prefix_prop_p.
13643 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
13644 Mark string as coming from a prefix property.
13645 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13646 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13648 2012-03-21 Chong Yidong <cyd@gnu.org>
13650 * xfaces.c (Vface_remapping_alist): Doc fix.
13652 2012-03-20 Eli Zaretskii <eliz@gnu.org>

13666 it fit in a valid range (Bug#11003).
13668 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13670 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13671 that is not from display property, accept the row as a "cursor
13672 row" if one of the string's character has a non-nil `cursor'
13673 property. Fixes cursor positioning when there are newlines in
13674 overlay strings, e.g. in icomplete.el. (Bug#11035)
13676 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13678 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13680 2012-03-12 Chong Yidong <cyd@gnu.org>
13682 * eval.c (inhibit_lisp_code): Rename from
13683 inhibit_window_configuration_change_hook; move from window.c.
13685 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13686 * window.c (run_window_configuration_change_hook)
13687 (syms_of_window): Callers changed.
13689 2012-03-11 Chong Yidong <cyd@gnu.org>
13691 * keymap.c (Fkey_description): Doc fix (Bug#9700).
13693 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
13695 2012-03-10 Chong Yidong <cyd@gnu.org>
13697 * frame.c (other_visible_frames): Don't assume the selected frame
13698 is visible (Bug#10955).
13700 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13702 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13704 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13706 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13707 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13710 2012-03-03 Glenn Morris <rgm@gnu.org>
13712 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13714 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13716 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13717 position past the first glyph_row that ends at ZV. (Bug#10902)
13718 (redisplay_window, next_element_from_string): Fix typos in
13720 (redisplay_window): Pass to move_it_vertically the margin in
13721 pixels, not in screen lines.
13723 2012-03-02 Glenn Morris <rgm@gnu.org>
13725 * buffer.c (buffer-list-update-hook): Doc fix.
13727 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13729 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13730 push_it before setting up the iterator for the first overlay
13731 string, even if we have an empty string loaded.
13732 (next_overlay_string): If there's an empty string on the iterator
13733 stack, pop the stack. (Bug#10903)
13735 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13737 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13738 Suggested by Stefan Monnier in
13739 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13740 * alloc.c (widen_to_Lisp_Object): New static function.
13741 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13742 and widening them to Lisp_Objects. This would work even if
13743 USE_LSB_TAG is defined and wide integers are used, which might
13744 happen in a future version of Emacs.
13746 2012-02-25 Chong Yidong <cyd@gnu.org>
13748 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

13753 before saving to clipboard manager.
13755 2012-02-24 Chong Yidong <cyd@gnu.org>
13757 * keyboard.c (process_special_events): Handle all X selection
13758 requests in kbd_buffer, not just the next one (Bug#8869).
13760 2012-02-23 Chong Yidong <cyd@gnu.org>
13762 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13763 call when setting menu-bar-lines and tool-bar-lines parameters.
13764 (unwind_create_frame_1): New helper function.
13766 * window.c (inhibit_window_configuration_change_hook): New var.
13767 (run_window_configuration_change_hook): Obey it.

13785 when computing $valmask.
13787 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13788 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13789 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13790 It's useless in that case, and it can cause problems on hosts
13791 that allocate halves of EMACS_INT values separately.
13792 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13793 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13794 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13795 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13796 it avoids undefined behavior on hosts where shifting right by more
13797 than the word width has undefined behavior.
13799 2012-02-19 Chong Yidong <cyd@gnu.org>
13801 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13802 (Funhandled_file_name_directory, Ffile_name_as_directory)
13803 (Fdirectory_file_name, Fexpand_file_name)
13804 (Fsubstitute_in_file_name): Protect against invalid file handler
13805 return values (Bug#10845).

13821 2012-02-15 Chong Yidong <cyd@gnu.org>
13823 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

13839 2012-02-12 Chong Yidong <cyd@gnu.org>
13841 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
13842 as that creates a dangerous corner case.
13844 * window.c (Fdelete_window_internal): Invalidate the mouse
13845 highlight (Bug#9904).
13847 2012-02-12 Glenn Morris <rgm@gnu.org>

13877 2012-02-07 Chong Yidong <cyd@gnu.org>
13879 * buffer.c (Fbuffer_local_variables)
13880 (buffer_lisp_local_variables): Handle unbound vars correctly;
13881 don't let Qunbound leak into Lisp.
13883 2012-02-07 Glenn Morris <rgm@gnu.org>
13885 * image.c (Fimagemagick_types): Doc fix.
13887 * image.c (imagemagick-render-type): Change it from a lisp object
13888 to an integer. Move the doc here from the lisp manual.

13905 2012-02-04 Eli Zaretskii <eliz@gnu.org>
13907 * w32.c (get_emacs_configuration_options):
13908 Include --enable-checking, if specified, in the return value.

13918 before BEGV. (Bug#10696)
13920 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
13922 Handle overflow when computing char display width (Bug#9496).
13923 * character.c (char_width): Return EMACS_INT, not int.
13924 (char_width, c_string_width): Check for overflow when
13925 computing the width; this is possible now that individual
13926 characters can have unbounded width. Problem introduced
13927 by merge from Emacs 23 on 2012-01-19.

13951 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
13953 (x_produce_glyphs): If the component of a composition is a null

13958 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
13959 first 2 arguments are identical. This makes inserting large
13960 output from a subprocess an order of magnitude faster on
13961 MS-Windows, where all sbrk'ed memory is always contiguous.

14414 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
14415 verifies glyph row's hash code--we have just reallocated the

14599 behave as if the cursor position were at the window margin.
14601 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14602 and the cursor position is out of bounds, behave as if the cursor
14603 position were at the window margin. (Bug#10075)
14605 2011-11-18 Chong Yidong <cyd@gnu.org>

14629 compute_line_metrics.
14630 (compute_line_metrics): Call row_hash, instead of computing the
14633 * dispnew.c (verify_row_hash): Call row_hash for computing the
14634 hash code of a row, instead of duplicating code from xdisp.c.
14636 * dispextern.h (row_hash): Add prototype.
14638 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

14744 The trivial performance wins aren't worth the portability hassles; see
14745 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14747 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14823 Otherwise, these inline functions do not conform to C99 and
14824 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14825 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14826 * intervals.c (adjust_intervals_for_insertion)

14829 (static_offset_intervals): Remove.
14830 (offset_intervals): Rewrite using the old contents of
14831 static_offset_intervals. The old version didn't conform to C99

15127 * sysdep.c (init_sys_modes): Fix the check for the controlling
15128 terminal (Bug#6649).
15130 2011-10-20 Eli Zaretskii <eliz@gnu.org>
15132 * dispextern.h (struct bidi_it): New member next_en_type.
15134 * bidi.c (bidi_line_init): Initialize the next_en_type member.
15135 (bidi_resolve_explicit_1): When next_en_pos is valid for the
15136 current character, check also for next_en_type being WEAK_EN.
15137 (bidi_resolve_weak): Don't enter the expensive loop if the current
15138 position is before next_en_pos. Record the bidi type of the first
15139 non-ET, non-BN character we find, in addition to its position.
15140 (bidi_level_of_next_char): Invalidate next_en_type when
15141 next_en_pos is over-stepped.
15143 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15145 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15146 * editfns.c: Rewrite current-time-zone so that it invokes
15147 the equivalent of (format-time-string "%Z") to get the time zone name.
15148 This fixes a bug when the time zone name contains characters that
15149 need converting from the system time locale to Emacs internal format.
15150 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15151 that patch fixed format-time-string to do the conversion, but
15152 I forgot to fix current-time-zone.
15153 (format_time_string): New function, containing most of
15154 what Fformat_time_string used to contain.
15155 (Fformat_time_string): Rewrite in terms of format_time_string.
15156 This doesn't change this function's behavior.
15157 (current-time-zone): Rewrite to use format_time_string.
15158 This fixes the bug reported by Michael Schierl in
15159 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15160 Jason Rumney's 2007-06-07 change worked around this bug, but
15162 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15164 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15166 * xdisp.c (start_display): If the character at POS is displayed
15167 via a display vector, reset IT->current.dpvec_index to zero.
15168 (try_window_reusing_current_matrix): If a line ends in a display
15169 vector or the next line starts in a display vector, continue
15170 redrawing the window even though the character position of
15171 start_row was reached.
15174 2011-10-18 Chong Yidong <cyd@gnu.org>
15176 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15177 with nobreak-char-display too.
15179 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15181 Fix part 3 of bug#9771.
15182 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15183 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15184 non-neutral characters if the current character is a paragraph
15185 separator (a.k.a. Newline). This avoids running the same
15186 expensive loop twice, once when we consume the preceding newline
15187 and the other time when the line actually needs to be displayed.
15188 Avoid the loop when we see neutrals on the base embedding level
15189 following a character whose directionality is the same as the
15190 paragraph's. This avoids running the expensive loop when a line
15191 ends in a long sequence of neutrals, like control characters.
15192 Add assertion against STRONG_AL type. Slightly rearrange code
15193 that determines the type of a neutral given the first non-neutral
15195 (bidi_level_of_next_char): Set next_en_pos to zero when
15196 invalidating its info.
15198 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15200 * xdisp.c (push_display_prop): Determine whether to record string
15201 or buffer position by IT->string, not by IT->method. Allow
15202 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15203 (move_it_vertically_backward): Don't look for character position
15204 immediately after the newline when in a continuation line.
15207 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15209 * window.c (coordinates_in_window): Rewrite and delabelize
15210 vertical border check. (Bug#5357) (Bug#9618)
15212 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15214 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15215 errors in XSetWindowBorder (bug#9310).
15217 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15219 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15220 avoid crash when xmalloc overrun checking is enabled.
15222 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15224 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15225 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15226 cursor motion with <left> and <right> arrow keys.
15228 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15229 some callers set that themselves.
15231 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15233 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15234 display string and the previous row comes from the same string and
15235 is empty. (Bug#9739) (Bug#9738)
15237 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15239 * doc.c (get_doc_string): Encode file name (bug#9735).
15241 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15243 * bidi.c (bidi_level_of_next_char):
15244 * xdisp.c (get_visually_first_element): Remove old incorrect
15245 comments regarding the Unicode Line Separator character.
15247 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15249 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15251 * alloc.c (Fgc_status): Do not access beyond zombies array
15252 boundary if nzombies > MAX_ZOMBIES.
15253 * alloc.c (dump_zombies): Add missing format specifier.
15255 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15257 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15258 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15260 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15261 Some packages use them to denote characters with modifiers.
15263 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15265 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15266 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15267 matching a pp-number. Rename parameter var to var1.
15269 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15271 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15273 2011-10-08 Glenn Morris <rgm@gnu.org>
15275 * callint.c (Fcall_interactively): Give a more explicit error for the
15276 'c' case with a non-character input. (Bug#8479)
15278 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15280 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15282 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15283 lines that are hscrolled on the left.
15285 * dispnew.c (buffer_posn_from_coords): Account for a possible
15286 presence of header-line. (Bug#4426)
15288 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15290 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15291 Don't advertise functionality which we discourage or doesn't work.
15293 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15295 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15296 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15297 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15298 this makes Emacs dump core during garbage collection on rare
15299 occasions. sizeof is obviously inferior to offsetof here, so
15300 stick with offsetof.
15301 (GC_POINTER_ALIGNMENT): New macro.
15302 (mark_memory): Omit 3rd (offset) arg; caller changed.
15303 Don't assume EMACS_INT alignment is the same as pointer alignment.
15305 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15307 * keyboard.c (read_key_sequence_remapped): New var.
15308 (read_key_sequence): Compute remapping in the right buffer.
15309 (command_loop_1): Use read_key_sequence's remapping directly.
15311 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15313 * dired.c (file_name_completion): Don't expand file name.
15314 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15315 before checking file name handler.
15317 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15318 they've been requested explicitly (bug#9591).
15320 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15322 * keymap.c (Fsingle_key_description): Use make_specified_string
15323 instead of build_string to build string from push_key_description.
15326 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15328 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15329 This fixes a Y2038 bug on 64-bit hosts.
15330 * buffer.c (reset_buffer):
15331 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15332 (Fclear_buffer_auto_save_failure):
15333 Use 0, not -1, to represent an unset failure time, since time_t
15334 might not be signed.
15336 Remove dependency on glibc malloc internals.
15337 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15338 Move back here from lisp.h, but with their new implementations.
15339 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15340 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15341 * charset.c (charset_table_init): New static var.
15342 (syms_of_charset): Use it instead of xmalloc. This removes a
15343 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15344 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15345 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15346 Move back to alloc.c.
15347 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15348 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15350 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15352 * nsterm.m (windowDidResize): Call x_set_window_size only when
15353 ns_in_resize is true. Otherwise set pixelwidth/height and
15354 call change_frame_size (Bug#9628).
15356 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15358 Port --enable-checking=all to Fedora 14 x86-64.
15359 * charset.c (syms_of_charset): Also account for glibc malloc's
15360 internal overhead when calculating the initial malloc maximum.
15362 Port --enable-checking=all to Fedora 14 x86.
15363 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15365 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15366 (overrun_check_realloc, overrun_check_free):
15367 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15368 That way, xmalloc returns a properly-aligned pointer even if
15369 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15370 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15371 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15372 into account when calculating the initial malloc maximum.
15373 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15374 Move here from alloc.c, so that charset.c can use it too.
15375 Properly align; the old code wasn't right for common 32-bit hosts
15376 when configured with --enable-checking=all.
15377 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15378 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15380 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15382 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15385 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15387 * xdisp.c (compute_display_string_end): If there's no display
15388 string at CHARPOS, return -1.
15390 * bidi.c (bidi_fetch_char): When compute_display_string_end
15391 returns a negative value, treat the character as a normal
15392 character not covered by a display string. (Bug#9624)
15394 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15396 * lread.c (Fread_from_string): Fix typo in docstring.
15398 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15400 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15401 newline, reseat the iterator instead of bidi-iterating there one
15402 character at a time. (Bug#9610)
15403 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15404 TO_CHARPOS if the bidi iterator is at base embedding level.
15406 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15408 * lread.c (readevalloop): Use correct code for NBSP.
15409 (read1): Likewise. (Bug#9608)
15411 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15413 * dbusbind.c (Fdbus_register_signal): When service is not
15414 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15416 2011-09-25 Glenn Morris <rgm@gnu.org>
15418 * buffer.c (truncate-lines): Doc fix.
15420 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15422 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15423 (Fset_window_next_buffers): Doc fix.
15425 2011-09-24 Glenn Morris <rgm@gnu.org>
15427 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15429 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15431 Fix minor problems found by static checking.
15432 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15433 * indent.c (Fvertical_motion): Fix == vs = typo.
15435 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15437 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15438 Default value is now t. Doc fix.
15440 * indent.c (Fvertical_motion): Compute and apply the overshoot
15441 logic when moving up, not only when moving down. Fix the
15442 confusing name and values of the it_overshoot_expected variable;
15443 logic changes accordingly. (Bug#9254) (Bug#9549)
15445 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15446 CHARPOS is covered by a display string which includes newlines.
15447 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15448 is covered by a display string with embedded newlines.
15450 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15452 * dbusbind.c (Fdbus_register_signal): Add match rule to
15453 Vdbus_registered_objects_table. (Bug#9581)
15454 (Fdbus_register_method, Vdbus_registered_objects_table):
15457 2011-09-24 Jim Meyering <meyering@redhat.com>
15459 do not ignore write error for any output size
15460 The previous change was incomplete.
15461 While it makes emacs --batch detect the vast majority of stdout
15462 write failures, errors were still ignored whenever the output size is
15463 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15464 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15465 && echo FAIL: ignored write error
15466 FAIL: ignored write error
15467 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15468 && echo FAIL: ignored write error
15469 FAIL: ignored write error
15470 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15472 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15474 * emacs.c (Fkill_emacs): In noninteractive mode exit
15475 non-successfully if a write error occurred on stdout. (Bug#9574)
15477 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15479 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15482 * dispextern.h (struct it): Update the comment documenting what
15485 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15487 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15488 a display string, extend search for cursor position to end of row.
15489 (find_row_edges): If the row ends in a newline from a display
15490 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15491 Handle the case of a display string with multiple newlines.
15492 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15493 non-empty line. Fixes confusing cursor motion with arrow keys at
15494 the beginning of a line that starts with whitespace.
15496 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15498 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15501 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15503 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15504 boolean (Bug#9154).
15506 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15508 * xdisp.c (display_line): Record maximum and minimum buffer
15509 positions even if no glyphs were produced (e.g., by a zero-width
15510 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15511 buffer positions that will be removed from the glyph row because
15513 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15514 column is beyond frame width: don't subtract 1 "pixel" when
15515 computing width of the stretch.
15516 (reseat_at_next_visible_line_start): Undo the change made on
15517 2011-09-17 that saved paragraph information and restored it after
15518 the call to `reseat'. (Bug#9545)
15520 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15522 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15523 and turn window cursor on if cleared (Bug#9415).
15525 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15527 * search.c (boyer_moore): Take unibyte characters from pattern
15528 literally. (Bug#9458)
15530 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15532 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15534 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15536 Fix minor problem found by static checking.
15537 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15538 initialized, to pacify gcc -Wuninitialized.
15540 * fileio.c: Report proper errno when syscall falls.
15541 (Finsert_file_contents): Save and restore errno,
15542 so that report_file_error outputs the correct diagnostic.
15543 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15545 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15547 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15549 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15551 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15552 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15554 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15556 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15557 about the current paragraph and restore it after the call to reseat.
15559 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15560 (bidi_find_paragraph_start): Search back for paragraph beginning
15561 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15562 (bidi_move_to_visually_next): Only trigger paragraph-related
15563 computations when the last character is a newline or at EOB, not
15564 just any NEUTRAL_B. (Bug#9470)
15566 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15567 truncated lines if point is covered by a display string. (Bug#9524)
15569 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15571 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15572 (cons_to_x_long): New function.
15573 (lisp_data_to_selection_data): Use it. Correct the test for
15574 short-versus-long data; it was negated. Break out of vector
15575 loop, for efficiency, when a long datum is discovered.
15577 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15579 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15581 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15583 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15584 GCC PR/17406) by declaring this function with external scope.
15586 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15588 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15589 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15591 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15593 * editfns.c (Fformat): Correctly handle text properties on "%%".
15595 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15597 * xterm.c (x_draw_composite_glyph_string_foreground):
15598 * w32term.c (x_draw_composite_glyph_string_foreground):
15599 * term.c (encode_terminal_code):
15600 * composite.c (composition_update_it, get_composition_id):
15601 * xdisp.c (get_next_display_element)
15602 (fill_composite_glyph_string): Add comments about special meaning
15603 of TAB characters in a composition.
15605 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15607 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15608 This occurs when processing a multibyte format.
15609 Problem reported by Wolfgang Jenker.
15611 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15613 * xdisp.c (try_cursor_movement): Only check for exact match if
15614 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15616 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15618 Remove unused external symbols.
15619 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15620 * xdisp.c (calc_pixel_width_or_height): Now static.
15621 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15622 * indent.c (check_display_width):
15623 * w32term.c: Fix comment to match code.
15624 * xterm.c, xterm.h (x_catching_errors): Remove.
15626 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15628 * xselect.c: Use signed conversions more consistently (Bug#9498).
15629 (selection_data_to_lisp_data): Assume incoming selection data are
15630 signed integers, not unsigned. This is to be consistent with
15631 outgoing selection data, which was modified to use signed integers
15632 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15633 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15634 expects long, not unsigned long.
15636 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15638 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15639 computation of loop end. Reported by Johan Bockgård
15642 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15644 * frame.c (Fother_visible_frames_p): Function deleted.
15646 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15648 * indent.c (compute_motion): Process display vector front to back
15649 rather than the other way around. (Bug#2496)
15651 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15653 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15655 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15657 * minibuf.c (Fread_from_minibuffer): Doc fix.
15659 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15661 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15662 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15664 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15666 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15667 value for non-existent files.
15669 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15671 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15672 set its "size" to -1. This will set the modtime_size field of
15673 the corresponding buffer to -1, which is what
15674 verify-visited-file-modtime expects for files that do not exist.
15677 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15679 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15681 * lisp.h: ... from here. push_key_description is no longer
15682 defined in keyboard.c, so its declaration should not be in
15683 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15684 logically belongs with push_key_description.
15686 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15688 * buffer.h: Include <sys/types.h> instead of <time.h>.
15689 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15690 Problem reported by Herbert J. Skuhra.
15692 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15694 * xml.c (parse_region): Make the parsing work for
15695 non-comment-starting XML files again (bug#9144).
15697 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15699 * image.c (gif_load): Fix calculation of bottom and right corner.
15702 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15704 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15705 redisplay in small windows.
15707 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15709 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15711 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15713 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15714 Operate on live windows only.
15716 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15718 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15720 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15722 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15723 only under bidi iteration.
15725 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15727 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15729 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15731 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15732 Without this fix, the command to link temacs failed due to an
15733 undefined symbol __builtin_isnan. This is because
15734 /usr/include/iso/math_c99.h #defines isnan(x) to
15735 __builtin_isnan(x), but the bundled gcc, which identifies itself
15736 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15738 * floatfns.c (isnan): #undef, and then #define to a clone of
15740 (Fisnan): Always define, since it's always available now.
15741 (syms_of_floatfns): Always define isnan at the Lisp level.
15743 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15745 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15747 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15749 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15750 The previous code assumed that file offsets (off_t values) fit in
15751 EMACS_INT variables, which is not true on typical 32-bit hosts.
15752 The code messed up by falsely reporting buffer overflow in cases
15753 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15754 when "big" contains more than 2**29 bytes, even though this
15755 inserts just one byte and does not overflow the buffer.
15756 (Finsert_file_contents): Store file offsets as off_t
15757 values, not as EMACS_INT values. Check for overflow when
15758 converting between EMACS_INT and off_t. When checking for
15759 buffer overflow or for overlap, take the offsets into account.
15760 Don't use EMACS_INT for small values where int suffices.
15761 When checking for overlap, fix a typo: ZV was used where
15762 ZV_BYTE was intended.
15763 (Fwrite_region): Don't assume off_t fits into 'long'.
15764 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15766 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15768 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15770 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15772 sprintf-related integer and memory overflow issues (Bug#9412).
15774 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15775 (esprintf, exprintf, evxprintf): New functions.
15776 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15777 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15778 (modify_event_symbol): Do not assume that the length of
15779 name_alist_or_stem is safe to alloca and fits in int.
15780 (Fexecute_extended_command): Likewise for function name and binding.
15781 (Frecursion_depth): Wrap around reliably on integer overflow.
15782 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15783 since some callers pass EMACS_INT values.
15784 (Fsingle_key_description): Don't crash if symbol name contains more
15785 than MAX_ALLOCA bytes.
15786 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15787 (get_minibuffer): Arg is now EMACS_INT, not int.
15788 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15789 (esprintf, exprintf, evxprintf): New decls.
15790 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15792 * dbusbind.c (signature_cat): New function.
15793 (xd_signature, Fdbus_register_signal):
15794 Do not overrun buffer; instead, report string overflow.
15796 * dispnew.c (add_window_display_history): Don't overrun buffer.
15797 Truncate instead; this is OK since it's just a log.
15799 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15800 even if the time zone offset is outlandishly large.
15801 Don't mishandle offset == INT_MIN.
15803 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15804 when creating daemon; the previous buffer-overflow check was incorrect.
15806 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15807 which has the guts of the old verror function.
15809 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15810 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15812 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15813 (font_unparse_xlfd): Don't blindly alloca long strings.
15814 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15815 fits in int, when using sprintf. Use single snprintf to count
15816 length of string rather than counting it via multiple sprintfs;
15817 that's simpler and more reliable.
15818 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15819 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15820 sprintf, in case result does not fit in int.
15822 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15823 (fontset_from_font): Print it.
15825 * frame.c (tty_frame_count): Now printmax_t, not int.
15826 (make_terminal_frame, set_term_frame_name): Print it.
15827 (x_report_frame_params): In X, window IDs are unsigned long,
15828 not signed long, so print them as unsigned.
15829 (validate_x_resource_name): Check for implausibly long names,
15830 and don't assume name length fits in 'int'.
15831 (x_get_resource_string): Don't blindly alloca invocation name;
15832 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15835 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15836 (xg_check_special_colors, xg_set_geometry):
15837 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15839 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15840 Use esprintf, not sprintf, in case result does not fit in int.
15842 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15843 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15844 it as a large positive number.
15845 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15846 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15848 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15849 in case result does not fit in int.
15851 * print.c (float_to_string): Detect width overflow more reliably.
15852 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15853 buffer overrun. Don't assume list length fits in 'int'. Treat
15854 print length of 0 as 0, not as infinity; to be consistent with other
15855 uses of print length in this function. Don't overflow print length
15856 index. Don't assume hash table size fits in 'long', or that
15857 vectorlike size fits in 'unsigned long'.
15859 * process.c (make_process): Use printmax_t, not int, to format
15860 process-name gensyms.
15862 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15864 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15865 to avoid potential buffer overrun.
15867 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15868 if X resource line is longer than 512 bytes.
15870 * xfns.c (x_window): Make sprintf buffer a bit bigger
15871 to avoid potential buffer overrun.
15873 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15875 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15877 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15879 Integer overflow fixes for scrolling, etc.
15880 Without these, Emacs silently mishandles large integers sometimes.
15881 For example, "C-u 4294967297 M-x recenter" was treated as if
15882 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15884 * xdisp.c (try_window_id): Check Emacs fixnum range before
15885 converting to 'int'.
15887 * window.c (window_scroll_line_based, Frecenter):
15888 Check that an Emacs fixnum is in range before assigning it to 'int'.
15889 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15890 values converted from Emacs fixnums.
15891 (Frecenter): Don't wrap around a line count if it is out of 'int'
15892 range; instead, treat it as an extreme value.
15893 (Fset_window_configuration, compare_window_configurations):
15894 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15896 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15897 that can exceed INT_MAX. Check that EMACS_INT value is in range
15898 before assigning it to the (possibly-narrower) index.
15899 (match_limit): Don't assume that a fixnum can fit in 'int'.
15901 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15904 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15905 (Fvertical_motion): Don't wrap around LINES values that don't fit
15906 in 'int'. Instead, treat them as extreme values. This is good
15907 enough for windows, which can't have more than INT_MAX lines anyway.
15909 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15911 * Require libxml/parser.h to avoid compilation warning.
15913 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15915 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15916 since this reportedly can destroy thread storage.
15918 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15920 * syntax.c (find_defun_start): Update all cache variables if
15921 exiting early (Bug#9401).
15923 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15925 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15927 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15928 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15929 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15931 * term.c (tty_append_glyph): New function.
15932 (produce_stretch_glyph): Static function and its prototype deleted.
15934 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15937 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15939 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15940 when checking :margin (Bug#9390).
15941 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15942 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15943 so that the name doesn't mislead. All uses changed.
15945 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15947 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15950 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15952 * xdisp.c (move_it_to): Don't bail out early when reaching
15953 position beyond to_charpos, if we are scanning backwards.
15954 (move_it_vertically_backward): When DY == 0, make sure we get to
15955 the first character in the line after the newline.
15957 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15959 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15960 (ccl_driver): Do not generate an out-of-range pointer.
15961 (Fccl_execute_on_string): Remove unnecessary check for
15962 integer overflow, noted by Stefan Monnier in
15963 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15964 Remove a FIXME that didn't need fixing.
15965 Simplify the newly-introduced buffer reallocation code.
15967 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15969 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15971 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15973 Integer and memory overflow issues (Bug#9196).
15975 * doc.c (get_doc_string): Rework so that
15976 get_doc_string_buffer_size is the actual buffer size, rather than
15977 being 1 less than the actual buffer size; this makes xpalloc more
15980 * image.c (x_allocate_bitmap_record, cache_image):
15981 * xselect.c (Fx_register_dnd_atom):
15982 Simplify previous changes by using xpalloc.
15984 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15985 since either will do and ptrdiff_t is convenient with xpalloc.
15987 * charset.c (charset_table_size)
15988 (struct charset_sort_data.priority): Now ptrdiff_t.
15989 (charset_compare): Don't overflow if priorities differ greatly.
15990 (Fsort_charsets): Don't assume list length fits in int.
15991 Check for size-calculation overflow when allocating sort data.
15992 (syms_of_charset): Allocate an initial charset table that is
15993 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15995 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15997 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15998 The actual value is always <= INT_MAX, and leaving it unsigned made
15999 overflow checking harder.
16001 * dispextern.h (struct glyph_matrix.rows_allocated)
16002 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16003 with xpalloc. The values are still always <= INT_MAX.
16005 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16007 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16008 (SAFE_NALLOCA): New macro.
16010 * region-cache.c (struct boundary.pos, find_cache_boundary)
16011 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16012 (set_cache_region, invalidate_region_cache)
16013 (revalidate_region_cache, know_region_cache, region_cache_forward)
16014 (region_cache_backward, pp_cache):
16015 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16016 so that ptrdiff_t * can be passed to xpalloc.
16017 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16018 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16019 (pp_cache): Don't assume cache_len fits in int.
16020 * region-cache.h: Adjust extern decls to match.
16022 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16023 EMACS_INT, since either will do, for xpalloc.
16025 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16026 (xnmalloc, xnrealloc, xpalloc): New functions.
16028 * bidi.c (bidi_shelve_header_size): New constant.
16029 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.

16032 * bidi.c (bidi_cache_shrink):
16033 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16035 Don't update size of array until after memory allocation succeeds,
16036 because xmalloc/xrealloc may not return.
16037 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16038 now that we have proper integer overflow checking.
16039 (record_overlay_string, overlay_strings): Catch overflows when
16040 calculating size of overlay_str_buf.
16042 * callproc.c (Fcall_process): Check for size overflow when
16043 calculating size of args2.
16044 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16045 Normally we prefer signed values, but sticking with ptrdiff_t would
16046 require adding more-complicated checks.
16048 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16049 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16050 Redo buffer-overflow calculations to avoid integer overflow.

16089 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16091 * emacs.c (main): Do not reallocate argv, since there is a null at
16092 the end that can be overwritten, and this way there's no need to
16093 worry about size-calculation overflow.
16094 (sort_args): Check for size-calculation overflow.
16096 * eval.c (init_eval_once, grow_specpdl): Don't update size until

16102 Check for integer overflow.
16103 (x_set_alpha): Do not assume XINT fits in int.
16105 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16106 This is for the members text_lines, text_cols, total_lines, total_cols,
16107 where the system imposes an 'int' limit.
16109 * fringe.c (Fdefine_fringe_bitmap):
16110 Don't update size until alloc works.

16115 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16116 Check for size-calculation overflow.
16117 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16118 do, as we prefer signed integers.
16119 (id_to_widget.max_size, id_to_widget.used)
16120 (xg_store_widget_in_map, xg_remove_widget_from_map)

16123 Use and return ptrdiff_t, not int.
16124 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16125 * gtkutil.h: Change prototypes to match the above.
16127 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

16174 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16175 for command line length. Do not attempt to address one before the
16176 beginning of an array, as that's not portable.

16204 Use ptrdiff_t, not int, for sizes.
16205 (Finternal_make_lisp_face, cache_face):
16206 Check for size calculation overflow.
16207 (cache_face): Treat size calculation overflows as if they were
16208 memory exhaustion (the usual treatment), rather than aborting.
16210 * xfns.c (x_encode_text, x_set_name_internal)
16211 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16212 sizes, since they can exceed INT_MAX in size. Check for size

16222 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16223 (X_LONG_MIN): New macros.
16224 Use them to make the following changes clearer.
16225 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16226 This change doesn't affect the value now, but it may help remind
16227 future maintainers not to raise the value too much later.
16228 (SELECTION_QUANTUM): Remove, replacing with ...
16229 (selection_quantum): ... new function, which avoids overflow.
16231 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16232 assumption that selection length fits in 'int'.
16233 (x_reply_selection_request, x_handle_selection_request)
16234 (x_get_window_property, receive_incremental_selection)

16249 Don't store size until memory allocation succeeds.
16250 (x_get_window_property): Plug memory leak on memory exhaustion.
16251 Don't double-block input; malloc is safe here. Don't assume 2**34
16252 - 4 fits in unsigned long. Add an xassert to check
16253 XGetWindowProperty overflow. Be more careful about overflow
16254 calculations, and distinguish size from memory overflow better.
16255 (receive_incremental_selection): When tracing, don't assume
16256 unsigned int is less than INT_MAX.
16257 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16258 harmful) conversions of unsigned short to int.

16260 in the range -65535 through -1 fit in an X unsigned short.
16261 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16262 result parameters unless successful. Rely on cons_to_unsigned
16263 to report problems with elements; the old code wasn't right anyway.
16264 (x_check_property_data): Check for int overflow; we cannot use
16265 a wider type due to X limits.
16266 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

16298 * lisp.h (hash_lookup, hash_put):
16299 * minibuf.c (Ftest_completion):
16300 Use ptrdiff_t for hash table indexes, not int (which is too
16301 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16302 32-bit --with-wide-int hosts).
16304 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16305 Add a FIXME comment about memory leaks.
16306 (syms_of_charset): Don't assume xmalloc returns.

16313 with outlandish widths.
16314 * character.h (sanitize_tab_width): Rename from sanitize_width,
16315 now that we have two such functions. All uses changed.

16334 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16335 (x_send_scroll_bar_event): Likewise. Check that the size does not
16336 exceed limits imposed by XClientMessageEvent, as well as the usual
16337 ptrdiff_t and size_t limits.
16339 * keyboard.c: Overflow, signedness and related fixes.
16340 (make_lispy_movement): Use same integer type in forward decl
16341 that is used in the definition.
16342 (read_key_sequence, keyremap_step):
16343 Change bufsize argument back to int, undoing my 2011-03-30 change.
16344 We prefer signed types, and int is wide enough here.
16345 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16346 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16347 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16348 length, not size_t. Use ptrdiff_t for index, not int.
16349 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16350 possibility of integer overflow.

16377 (png_load, gif_load, svg_load_image):
16378 Prefer int to unsigned where either will do.
16379 (tiff_handler): New function, combining the cores of the
16380 old tiff_error_handler and tiff_warning_handler.
16381 This function is rewritten to use vsnprintf and thereby avoid
16382 stack buffer overflows. It uses only the features of vsnprintf
16383 that are common to both POSIX and native Microsoft.
16384 (tiff_error_handler, tiff_warning_handler): Use it.
16385 (tiff_load, gif_load, imagemagick_load_image):
16386 Don't assume :index value fits in 'int'.
16387 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16388 (imagemagick_load_image): Check that crop parameters fit into
16389 the integer types that MagickCropImage accepts. Don't assume
16390 Vimagemagick_render_type has a nonnegative value. Don't assume
16391 size_t fits in 'long'.
16392 (gs_load): Use printmax_t to print the widest integers possible.
16393 Check for integer overflow when computing image height and width.
16395 2011-08-26 Eli Zaretskii <eliz@gnu.org>
16397 * xdisp.c (redisplay_window): Don't force window start if point

16405 handle_single_display_spec, not just 1 or zero.
16406 (handle_single_display_spec): If the display spec is of the form
16407 `(space ...)', and specifies display in the text area, return 2
16409 (try_cursor_movement): Check for the need to scroll more
16410 accurately, and prefer exact match for point under bidi.
16411 Don't advance `row' beyond the last row of the window.

16428 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16429 buffers, return left-to-right.
16430 (set_cursor_from_row): Consider candidate row a win if its glyph
16431 represents a newline and point is on that newline. Fixes cursor
16432 positioning on the newline at EOL of R2L text within L2R
16433 paragraph, and vice versa.
16434 (try_cursor_movement): Check continued rows, in addition to
16435 continuation rows. Fixes unwarranted scroll when point enters a
16436 continued line of R2L text within an L2R paragraph, or vice versa.
16437 (cursor_row_p): Consider the case of point being equal to
16438 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16439 from the end of a short line to the beginning of a continued line
16440 of R2L text within L2R paragraph.
16441 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

16459 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
16460 extra slot even if the purpose is char-code-property-table.
16462 2011-08-23 Eli Zaretskii <eliz@gnu.org>
16464 * xdisp.c (redisplay_window): When computing centering_position,
16465 account for the height of the header line. (Bug#8874)
16467 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16468 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16469 candidate is selected by the mouse, and that candidate has a
16470 composed character under the mouse.
16472 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16473 coordinates reported by pos-visible-in-window-p for a composed
16474 character in column zero.
16476 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

16483 consider it a hit if to_charpos is anywhere in the range of the
16484 composed buffer positions.
16486 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16488 * image.c (gif_load): Don't assume that each subimage has the same
16489 dimensions as the base image. Handle disposal method that is
16490 "undefined" by the gif spec (Bug#9335).
16492 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16494 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16500 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16501 from an Org mode buffer to a Speedbar frame.
16503 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16504 a composition, take its buffer position from IT->cmp_it.charpos.
16505 Fixes cursor positioning at the beginning of a line that begins
16506 with a composed character.
16508 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16510 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16511 character bidirectional type, use STRONG_L instead. Fixes crashes
16512 in a buffer produced by `describe-categories'.
16514 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16515 members before the level stack, so they would be saved and
16516 restored when copying iterator state. Fixes incorrect reordering
16517 around TABs covered by display properties.
16519 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16521 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16526 (internal_condition_case_2, internal_condition_case_n):
16527 Remove unnecessary aborts (Bug#9081).
16529 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16531 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16532 has no `load' handler, try opening the file locally. (Bug#9311)
16534 2011-08-16 Ken Brown <kbrown@cornell.edu>
16536 * gmalloc.c: Expand comment.
16538 2011-08-16 Eli Zaretskii <eliz@gnu.org>

16554 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
16555 in the static heap.
16556 [CYGWIN] (special_realloc): New function.
16557 (_realloc_internal_nolock) [CYGWIN]: Use the new function on

16573 * chartab.c: Improve commentary for the uniprop_table API.
16575 * bidi.c (bidi_paragraph_init): Support zero value of
16576 bidi_ignore_explicit_marks_for_paragraph_level.

16589 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16591 * xdisp.c (move_it_in_display_line_to): Don't invoke
16592 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16593 ppos_it. Fixes vertical cursor motion when line beginning is
16594 covered by an image. (Bug#9296)
16596 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16598 * nsterm.h (ns_run_ascript): Declare.
16599 (NSAPP_DATA2_RUNASSCRIPT): Define.
16601 * nsfns.m (as_script, as_result, as_status): New static variables.
16602 (ns_run_ascript): New function.
16603 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16604 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16605 the event loop. Get status from as_status (Bug#7276).
16607 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16608 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16609 the event loop (Bug#7276).
16611 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16613 * gnutls.c (QCgnutls_bootprop_priority)

16615 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
16616 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
16617 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
16618 (QCgnutls_bootprop_verify_hostname_error)

16635 (Fnetwork_interface_list): Allocate in increments of bytes instead
16636 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16637 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16639 (struct ifflag_def): notrailers is smart on OSX.
16640 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16641 Get hardware address with getifaddrs if available.
16643 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16645 * xdisp.c (iterate_out_of_display_property): xassert that
16646 IT->position is set to within IT->object's boundaries. Break from
16647 the loop as soon as EOB is reached; avoids infloops in redisplay
16648 when IT->position is set up wrongly due to some bug.
16649 Set IT->current to match the bidi iterator unconditionally.
16650 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16651 entry. Force push_it to save on the stack the current
16652 buffer/string position, to be restored by pop_it. Fix flags in
16653 the iterator structure wrt the object coming from a display
16654 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16655 properties. (Bug#9284)
16657 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16659 * fontset.c (fontset_get_font_group): Add proper type checks.

16672 no-display-properties-and-no-overlays under bidi display.
16673 Set disp_pos in the bidi iterator to avoid searches for display
16674 properties and overlays.
16676 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16678 * editfns.c (Fset_time_zone_rule): Document relationship with the

16687 restore_point_unwind (Bug#5984).
16689 2011-08-07 Juri Linkov <juri@jurta.org>
16691 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16692 to show the arg `TIME' instead of `TIMEVAL'.
16694 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16696 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16697 display property strides EOL and includes a newline, as in
16698 longlines-mode. (Bug#9254)
16699 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16700 word-wrap under bidirectional display. (Bug#9224)
16702 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16703 is non-zero, even if the data buffer is NULL. Fixes a crash in
16704 vertical-motion with longlines-mode. (Bug#9254)
16706 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16708 * bidi.c <bidi_cache_total_alloc>: Now static.
16709 (bidi_initialize): Initialize bidi_cache_total_alloc.
16711 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16714 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16715 amount allocated this far in `bidi_cache_total_alloc'.
16716 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16717 non-zero, only free the data buffer without restoring the cache
16718 contents. All callers changed.
16720 * dispextern.h (bidi_unshelve_cache): Update prototype.
16722 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16723 (move_it_in_display_line, move_it_to)
16724 (move_it_vertically_backward, move_it_by_lines): Replace the call
16725 to xfree to an equivalent call to bidi_unshelve_cache.
16726 (move_it_in_display_line_to): Fix logic of returning
16727 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16729 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16731 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16732 came from a string character with a `cursor' property. (Bug#9229)
16734 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16736 * Makefile.in (LIB_PTHREAD): New variable.
16737 (LIBES): Add LIB_PTHREAD (Bug#9216).
16739 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16740 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16742 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16744 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16746 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16748 * xterm.c (x_find_topmost_parent): New function.
16749 (x_set_frame_alpha): Find topmost parent window with
16750 x_find_topmost_parent and set the property there also (bug#9181).
16751 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16753 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16755 * callproc.c (Fcall_process): Avoid vfork clobbering
16756 the local vars buffer, coding_systems, current_dir.

16764 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16765 so that it is not optimized away.
16767 * xdisp.c (compute_display_string_pos): Remove unused local.
16769 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16771 Fix slow cursor motion and scrolling in large buffers with

16776 * xdisp.c: Remove one-slot cache of display string positions.
16777 (compute_display_string_pos): Accept an additional argument

16779 for a display string or property. If found, set DISP_PROP_P
16782 * bidi.c (bidi_fetch_char): Accept an additional argument
16783 DISP_PROP_P, and pass it to compute_display_string_pos.
16784 Only handle text covered by a display string if DISP_PROP_P is returned
16785 non-zero. All callers of bidi_fetch_char changed.
16787 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16789 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.

16793 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16794 last character M-[char] is translated to ESC [char] (bug#7541).
16796 2011-08-02 Kenichi Handa <handa@m17n.org>
16798 * lisp.h (uniprop_table): Extern it.
16800 * chartab.c (uniprop_table): Make it non-static.
16802 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16804 * xdisp.c (forward_to_next_line_start): Accept additional argument
16805 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16807 (reseat_at_next_visible_line_start): Use the bidi iterator state
16808 returned by forward_to_next_line_start to restore the state of
16809 it->bidi_it after backing up to previous newline. (Bug#9212)
16811 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16813 * regex.c (re_comp): Protoize.
16814 (re_exec): Fix return type.
16815 (regexec): Fix type of `ret'. (Bug#9203)
16817 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16819 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16820 This is needed if max-image-size is a floating-point number.
16822 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16824 * print.c (print_object): Print empty symbol as ##.

16835 contents (Bug#9176).
16836 (EmacsTooltip -init): Remove bezels and add shadows to
16839 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16840 or scroll bar (Bug#8470).
16842 * nsfont.m (nsfont_open): Remove assignment to voffset and

16846 * nsterm.h (nsfont_info): Remove voffset field.
16848 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16850 Implement strike-through and overline on NextStep (Bug#8863).
16852 * nsfont.m (nsfont_open): Use underline position provided by font,
16853 instead of hard-coded value of 2.
16854 (nsfont_draw): Call ns_draw_text_decoration instead.

16869 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16871 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16872 Without this fix, if a signal arrives just after memory fills up,
16873 'malloc' might be invoked reentrantly.
16875 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16876 In other words, assume that every image size is allowed, on non-X
16877 hosts. This assumption is probably wrong, but it lets Emacs compile.
16879 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16881 * regex.c (re_iswctype): Convert return values to boolean.
16883 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16885 * xdisp.c (compute_display_string_pos): Don't use cached display
16886 string position if the buffer had its restriction changed.
16889 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16891 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16893 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16895 Integer signedness and overflow and related fixes. (Bug#9079)
16897 * bidi.c: Integer size and overflow fixes.
16898 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16899 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16900 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16901 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16902 (bidi_find_other_level_edge):
16903 Use ptrdiff_t instead of EMACS_INT where either will do.
16904 This works better on 32-bit hosts configured --with-wide-int.
16905 (bidi_cache_ensure_space): Check for size-calculation overflow.
16906 Use % rather than repeated addition, for better worst-case speed.
16907 Don't set bidi_cache_size until after xrealloc returns, because it
16909 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16910 (bidi_cache_ensure_space): Also check that the bidi cache size
16911 does not exceed that of the largest Lisp string or buffer. See Eli
16912 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16914 * alloc.c (__malloc_size_t): Remove.
16915 All uses replaced by size_t. See Andreas Schwab's note
16916 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16918 * image.c: Improve checking for integer overflow.
16919 (check_image_size): Assume that f is nonnull, since
16920 it is always nonnull in practice. This is one less thing to
16921 worry about when checking for integer overflow later.
16922 (x_check_image_size): New function, which checks for integer
16923 overflow issues inside X.
16924 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16925 This removes the need for a memory_full check.
16926 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16927 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16928 (xbm_read_bitmap_data): Change locals back to 'int', since
16929 their values must fit in 'int'.
16930 (xpm_load_image, png_load, tiff_load):
16931 Invoke x_create_x_image_and_pixmap earlier,
16932 to avoid much needless work if the image is too large.
16933 (tiff_load): Treat overly large images as if
16934 x_create_x_image_and_pixmap failed, not as malloc failures.
16935 (gs_load): Use x_check_image_size.
16937 * gtkutil.c: Omit integer casts.
16938 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16939 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16941 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16943 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16944 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16945 would wrongly return t on a 64-bit host.
16947 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16948 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16949 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16950 and therefore cause GCC to emit a bogus diagnostic in some cases.
16952 * image.c: Integer signedness and overflow and related fixes.
16953 This is not an exhaustive set of fixes, but it's time to
16954 record what I've got.
16955 (lookup_pixel_color, check_image_size): Remove redundant decls.
16956 (check_image_size): Don't assume that arbitrary EMACS_INT values
16957 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16958 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16959 (tiff_load, imagemagick_load_image):
16960 Check for overflow in size calculations.
16961 (x_create_x_image_and_pixmap): Remove unnecessary test for
16962 xmalloc returning NULL; that can't happen.
16963 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16964 (xpm_color_bucket): Use better integer hashing function.
16965 (xpm_cache_color): Don't possibly over-allocate memory.
16966 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16967 (gif_memory_source):
16968 Use ptrdiff_t, not int or size_t, to record sizes.
16969 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16970 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16971 either works, as we prefer signed integers.
16972 (tiff_read_from_memory, tiff_write_from_memory):
16973 Return tsize_t, not size_t, since that's what the TIFF API wants.
16974 (tiff_read_from_memory): Don't fail simply because the read would
16975 go past EOF; instead, return a short read.
16976 (tiff_load): Omit no-longer-needed casts.
16977 (Fimagemagick_types): Don't assume size fits into 'int'.
16979 Improve hashing quality when configured --with-wide-int.
16980 * fns.c (hash_string): New function, taken from sxhash_string.
16981 Do not discard information about ASCII character case; this
16982 discarding is no longer needed.
16983 (sxhash-string): Use it. Change sig to match it. Caller changed.
16984 * lisp.h: Declare it.
16985 * lread.c (hash_string): Remove, since we now use fns.c's version.
16986 The fns.c version returns a wider integer if --with-wide-int is
16987 specified, so this should help the quality of the hashing a bit.
16989 * emacs.c: Integer overflow minor fix.
16990 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16991 Define only if GNU_LINUX.
16992 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16994 * dispnew.c: Integer signedness and overflow fixes.
16995 Remove unnecessary forward decls, that were a maintenance hassle.
16996 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16998 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16999 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17000 (prepare_desired_row, line_draw_cost):
17001 Use int, not unsigned, where either works.
17002 (save_current_matrix, restore_current_matrix):
17003 Use ptrdiff_t, not size_t, where either works.
17004 (init_display): Check for overflow more accurately, and without
17005 relying on undefined behavior.
17007 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17008 Remove, replacing with the new symbols in lisp.h. All uses changed.
17009 * fileio.c (make_temp_name):
17010 * filelock.c (lock_file_1, lock_file):
17011 * xdisp.c (message_dolog):
17012 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17013 Use pMd etc. instead.
17014 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17015 replacing the pWIDE etc. symbols removed from editfns.c.
17017 * keyboard.h (num_input_events): Now uintmax_t.
17018 This is (very slightly) less likely to mess up due to wraparound.
17021 * buffer.c: Integer signedness fixes.
17022 (alloc_buffer_text, enlarge_buffer_text):
17023 Use ptrdiff_t rather than size_t when either will do, as we prefer
17026 * alloc.c: Integer signedness and overflow fixes.
17027 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17028 (__malloc_size_t): Default to size_t, not to int.
17029 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17030 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17031 Prefer ptrdiff_t to size_t when either would do, as we prefer
17033 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17034 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17035 Now const. Initialize with values that are in range even if char
17037 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17038 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17039 These functions do the right thing with sizes > 2**32.
17040 (check_depth): Now ptrdiff_t, not int.
17041 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17042 Adjust to new way of storing sizes. Check for size overflow bugs
17044 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17045 slightly wrong anyway, as it missed one instance of
17046 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17047 (refill_memory_reserve): Omit needless cast to size_t.
17048 (mark_object_loop_halt): Mark as externally visible.
17050 * xselect.c: Integer signedness and overflow fixes.
17051 (Fx_register_dnd_atom, x_handle_dnd_message):
17052 Use ptrdiff_t, not size_t, since we prefer signed.
17053 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17054 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17055 x_dnd_atoms_size and x_dnd_atoms_length.
17057 * doprnt.c: Prefer signed to unsigned when either works.
17059 * doprnt.c (doprnt):
17061 * xdisp.c (vmessage):
17062 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17063 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17064 prefer signed arithmetic to avoid comparison confusion.
17065 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17066 but is a bit tricky.
17068 Assume freestanding C89 headers, string.h, stdlib.h.
17069 * data.c, doprnt.c, floatfns.c, print.c:
17070 Include float.h unconditionally.
17071 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17072 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17073 * regex.c: Likewise for stddef.h, string.h.
17074 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17075 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17076 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17077 (STDC_HEADERS): Remove obsolete defines.
17078 * sysdep.c: Include limits.h unconditionally.
17080 Assume support for memcmp, memcpy, memmove, memset.
17081 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17082 * regex.c (memcmp, memcpy):
17083 Remove; we assume C89 now.
17085 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17086 (__malloc_safe_bcopy): Remove; no longer needed.
17088 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17089 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17090 well either way, and we prefer signed to unsigned.
17092 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17094 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17095 closes the connection while we're reading (bug#9182).
17097 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17099 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17100 are specified (Bug#9168).
17102 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17104 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17105 Found by GCC static checking and --with-wide-int on a 32-bit host.
17107 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17109 * xdisp.c (compute_display_string_pos): Fix logic of caching
17110 previous display string position. Initialize cached_prev_pos to
17111 -1. Fixes slow-down at the beginning of a buffer.
17113 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17115 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17116 for attrs[LFACE_FONTSET_INDEX].
17118 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17120 * xml.c (parse_region): Remove unused local
17121 that was recently introduced.
17123 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17125 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17126 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17128 * xdisp.c (move_it_in_display_line_to): Record the best matching
17129 position for TO_CHARPOS while scanning the line, and restore it on
17130 exit if none of the characters scanned was an exact match.
17131 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17132 when exact match is impossible due to invisible text, and the
17133 lines are truncated.
17135 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17137 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17140 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17142 Fix a significant slow-down of cursor motion with C-n, C-p,
17143 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17144 auto-repeat under bidi redisplay in fontified buffers.
17145 * xdisp.c (compute_stop_pos_backwards): New function.
17146 (next_element_from_buffer): Call compute_stop_pos_backwards to
17147 find a suitable prev_stop when we find ourselves before
17149 (reseat): Don't look for prev_stop, as that could mean a very long
17151 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17152 <cached_disp_overlay_modiff>: Cache for last found display string
17154 (compute_display_string_pos): Return the cached position if asked
17155 about the same buffer in the same area of character positions, and
17156 the buffer wasn't changed since the time the display string
17157 position was cached.
17159 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17161 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17162 is an integer, which is important for empty lines. (Bug#9149)
17164 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17166 * frame.c (Fmodify_frame_parameters): In tty case, update the
17167 default face if necessary (Bug#4238).
17169 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17171 * editfns.c (Fstring_to_char): No need to explain what a character
17172 is in the docstring (Bug#6576).
17174 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17176 * xml.c (parse_region): Make sure we always return a tree.
17178 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17180 * xml.c (parse_region): If a document contains only comments,
17183 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17185 * xml.c (make_dom): Return comments, too.
17187 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17190 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17191 and the surrounding thread.
17192 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17193 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17194 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17196 * s/openbsd.h (BROKEN_SIGIO): Define.
17197 * unexelf.c (unexec) [__OpenBSD__]:
17198 Don't update the .mdebug section of the Alpha COFF symbol table.
17200 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17202 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17205 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17207 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17208 This fixes some race conditions on the permissions of any newly
17211 * alloc.c (valid_pointer_p): Use pipe, not open.
17212 This fixes some permissions issues when debugging.
17214 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17215 If fchown fails to set both uid and gid, try to set just gid,
17216 as that is sometimes allowed. Adjust the file's mode to eliminate
17217 setuid or setgid bits that are inappropriate if fchown fails.
17219 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17221 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17222 to compare Lisp_Objects.
17223 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17224 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17225 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17227 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17229 * lread.c (read_integer): Unread even EOF character.
17230 (read1): Likewise. Properly record start position of symbol.
17232 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17233 symbol character follows.
17235 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17237 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17238 This works around a problem with the previous change to Fcopy_file.
17239 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17240 and without this change, GCC might complain about discarding
17241 fchown's return value.
17243 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17245 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17247 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17249 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17251 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17253 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17254 it's used from the C level.
17256 * process.c: Use the same condition for POLL_FOR_INPUT in both
17257 keyboard.c and process.c (bug#1858).
17259 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17261 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17262 (Fgnutls_boot): Use it.
17264 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17266 * doc.c (Fsubstitute_command_keys): Revert last change.
17268 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17270 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17271 quotes the next character, and doesn't affect other longer
17272 sequences (bug#8935).
17274 * lread.c (syms_of_lread): Clarify that is isn't only
17275 `eval-buffer' and `eval-defun' that's affected by
17276 `lexical-binding' (bug#8460).
17278 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17280 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17281 bidi redisplay when a line includes both an image and is truncated.
17283 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17285 Fix minor problems found by static checking.
17286 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17287 (elsz): Now a signed constant, not a size_t var. We prefer signed
17288 types to unsigned, to avoid integer comparison confusion. Without
17289 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17290 "cannot optimize loop, the loop counter may overflow", a symptom
17292 * indent.c (Fvertical_motion): Mark locals as initialized.
17293 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17295 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17297 * search.c (Fre_search_backward): Mention `case-fold-search' in
17298 all the re_search_* functions (bug#8138).
17300 * keyboard.c (Fopen_dribble_file): Document when the file is
17303 2011-07-14 Eli Zaretskii <eliz@gnu.org>
17305 * bidi.c (bidi_dump_cached_states): Fix format of displaying
17308 Support bidi reordering of display and overlay strings.
17309 * xdisp.c (compute_display_string_pos)
17310 (compute_display_string_end): Accept additional argument STRING.
17311 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
17312 (reseat_to_string): Initialize bidi_it->string.s and
17313 bidi_it->string.schars.
17314 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
17315 NULL (avoids a crash in bidi_paragraph_init).
17316 Initialize itb.string.lstring.
17317 (init_iterator): Call bidi_init_it only of a valid
17318 buffer position was specified. Initialize paragraph_embedding to
17320 (reseat_to_string): Initialize the bidi iterator.
17321 (display_string): If we need to ignore text properties of
17322 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17323 original value of -1 will not work with bidi.)
17324 (compute_display_string_pos): First arg is now struct
17325 `text_pos *'; all callers changed. Support display properties on
17327 (compute_display_string_end): Support display properties on Lisp
17329 (init_iterator, reseat_1, reseat_to_string): Initialize the
17330 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17331 when iterating on a string not from display properties).
17332 (compute_display_string_pos, compute_display_string_end):
17333 Fix calculation of the object to scan. Fixes an error when using
17335 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17336 base_level_stop; instead, set base_level_stop to BEGV.
17337 Fixes crashes in vertical-motion.
17338 (next_element_from_buffer): Improve commentary for when
17339 the iterator is before prev_stop.
17340 (init_iterator): Initialize bidi_p from the default value of
17341 bidi-display-reordering, not from buffer-local value. Use the
17342 buffer-local value only if initializing for buffer iteration.
17343 (handle_invisible_prop): Support invisible properties on strings
17344 that are being bidi-reordered.
17345 (set_iterator_to_next): Support bidi reordering of C strings and
17347 (next_element_from_string): Support bidi reordering of Lisp
17349 (handle_stop_backwards): Support Lisp strings as well.
17350 (display_string): Support display of R2L glyph rows.
17351 Use IT_STRING_CHARPOS when displaying from a Lisp string.
17352 (init_iterator): Don't initialize it->bidi_p for strings
17354 (reseat_to_string): Initialize it->bidi_p for strings here.
17355 (next_element_from_string, next_element_from_c_string)
17356 (next_element_from_buffer): Add xassert's for correspondence
17357 between IT's object being iterated and it->bidi_it.string
17359 (face_before_or_after_it_pos): Support bidi iteration.
17360 (next_element_from_c_string): Handle the case of the first string
17361 character that is not the first one in the visual order.
17362 (get_visually_first_element): New function, refactored from common
17363 parts of next_element_from_buffer, next_element_from_string, and
17364 next_element_from_c_string.
17365 (tool_bar_lines_needed, redisplay_tool_bar)
17366 (display_menu_bar): Force left-to-right direction. Add a FIXME
17367 comment for making that be controlled by a user option.
17368 (push_it, pop_it): Save and restore the state of the

17815 * alloc.c (mark_buffer):
17816 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
17817 (clone_per_buffer_values): Don't assume that
17818 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
17819 This isn't true in general, and it's particularly not true
17820 if Emacs is configured with --with-wide-int.
17821 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17822 New macros, used in the buffer.c change.

17858 Random fixes. E.g., (random) never returned negative values.
17859 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17860 subseconds part to the entropy, as that's a bit more random.
17861 Prefer signed to unsigned, since the signedness doesn't matter and
17862 in general we prefer signed. When given a limit, use a
17863 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17864 latter isn't right if USE_2_TAGS_FOR_INTS.
17865 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17866 not 0..VALMASK. Don't discard "excess" bits that random () returns.
17868 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
17870 * textprop.c (text_property_stickiness):
17871 Obey Vtext_property_default_nonsticky.

17878 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
17879 This is more efficient than Ffile_directory_p and avoids a minor race.
17881 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
17883 * buffer.c (Foverlay_put): Say what the return value is
17886 * fileio.c (barf_or_query_if_file_exists): Check first if the file
17887 is a directory before asking whether to use the file name
17889 (barf_or_query_if_file_exists): Make the "File is a directory"
17890 error be more correct.
17892 * fns.c (Frequire): Remove the mention of the .gz files, since
17893 that's installation-specific, but keep the mention of
17894 `get-load-suffixes'.

17906 Qgnutls_bootprop_verify_error (which is no longer used).
17908 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
17909 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
17910 Also (re)move comments that are misplaced or no longer relevant.
17912 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17914 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

17973 (syms_of_keymap): Defsubr make-composed-keymap.
17974 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

18011 * eval.c (struct backtrace): Simplify and port the data structure.
18012 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18013 signed bit field, as this assumption is not portable and it makes
18014 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18015 "char debug_on_exit : 1" as this is not portable either; instead,
18016 use the portable "unsigned int debug_on_exit : 1". Remove unused
18017 member evalargs. Remove obsolete comments about cc bombing out.
18019 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18247 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18248 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18249 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18251 (debug_method_add): Use va_list and vsprintf rather than relying
18252 on undefined behavior with wrong number of arguments.
18253 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18254 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18255 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18256 since we're not interested in debugging glyphs with old libraries.
18257 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18258 GCC 4.6.0's static checking.
18260 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18262 Integer overflow and signedness fixes (Bug#8873).
18263 A few related buffer overrun fixes, too.

18271 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
18272 (x_create_bitmap_from_xpm_data):
18273 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
18274 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
18276 * xfaces.c (load_pixmap):
18277 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
18278 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18279 (.bitmaps_last, struct x_output.icon_bitmap):
18280 Use ptrdiff_t, not int, for bitmap indexes.
18281 (x_allocate_bitmap_record): Check for size overflow.
18282 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18284 Use ptrdiff_t, not int, for overlay counts.
18285 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18286 * editfns.c (overlays_around, get_pos_property):
18287 * textprop.c (get_char_property_and_overlay):
18288 * xdisp.c (next_overlay_change, note_mouse_highlight):
18289 * xfaces.c (face_at_buffer_position):
18290 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18291 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18292 (Fnext_overlay_change, Fprevious_overlay_change)
18293 (mouse_face_overlay_overlaps, Foverlays_in):
18294 Use ptrdiff_t, not int, for sizes.
18295 (overlays_at, overlays_in): Check for size-calculation overflow.
18297 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18299 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18300 (x_session_initialize): Do not assume string length fits in int.
18302 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18303 This is unlikely, but can occur if DPI is outlandish.
18305 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18306 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18308 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18309 * xrdb.c (magic_file_p, search_magic_path):
18310 Omit last arg SUFFIX; it was always 0. All callers changed.
18311 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18313 * xfont.c (xfont_match): Avoid need for strlen.
18315 * xfns.c: Don't assume strlen fits in int.
18316 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18318 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18319 not unsigned long, as we prefer signed integers. All callers changed.
18320 Detect integer overflow in repeat count.
18321 (message_dolog): Don't assume print length fits in 39 bytes.
18322 (display_mode_element): Don't assume strlen fits in int.
18324 * termcap.c: Don't assume sizes fit in int and never overflow.
18325 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18326 (gobble_line): Check for size-calculation overflow.
18328 * minibuf.c (Fread_buffer):
18329 * lread.c (intern, intern_c_string):
18330 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18331 Don't assume string length fits in int.
18333 * keyboard.c (parse_tool_bar_item):
18334 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18336 * font.c: Don't assume string length fits in int.
18337 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18338 Use ptrdiff_t, not int.
18339 (font_intern_prop): Don't assume string length fits in int.
18340 Don't assume integer property fits in fixnum.
18341 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18343 * filelock.c: Fix some buffer overrun and integer overflow issues.
18344 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18345 Reformulate so as not to need the command string.
18346 Invoke gzip -cd rather than gunzip, as it's more portable.
18347 (lock_info_type, lock_file_1, lock_file):
18348 Don't assume pid_t and time_t fit in unsigned long.
18349 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18350 (current_lock_owner): Prefer signed type for sizes.
18351 Use memcpy, not strncpy, where memcpy is what is really wanted.
18352 Don't assume (via atoi) that time_t and pid_t fit in int.
18353 Check for time_t and/or pid_t out of range, e.g., via a network share.
18354 Don't alloca where an auto var works fine.
18356 * fileio.c: Fix some integer overflow issues.
18357 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18358 Don't assume string length fits in int.
18359 (directory_file_name): Don't assume string length fits in long.
18360 (make_temp_name): Don't assume pid fits in int, or that its print
18361 length is less than 20.
18363 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18365 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18367 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18369 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18370 We prefer signed integers, even for size calculations.
18372 * emacs.c: Don't assume string length fits in 'int'.
18373 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18374 (main): Don't invoke strlen when not needed.
18376 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18377 (XD_DEBUG_MESSAGE): Don't waste a byte.
18379 * callproc.c (getenv_internal_1, getenv_internal)
18380 (Fgetenv_internal):
18381 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18383 * lread.c (invalid_syntax): Omit length argument.
18384 All uses changed. This doesn't fix a bug, but it simplifies the
18385 code away from its former Hollerith-constant appearance, and it's
18386 one less 'int' to worry about when looking at integer-overflow issues.
18387 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18389 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18390 This didn't break anything, but it didn't help either.
18391 It's confusing to put a bogus integer in a place where the actual
18392 value does not matter.
18393 (LIST_END_P): Remove unused macro and its bogus comment.
18394 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18396 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18397 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18399 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18400 We prefer signed types, and the value cannot exceed the EMACS_INT
18401 range anyway (because otherwise the length would not be representable).
18402 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18403 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18404 This avoids a GCC warning when WIDE_EMACS_INT.
18406 * indent.c (sane_tab_width): New function.
18407 (current_column, scan_for_column, Findent_to, position_indentation)
18408 (compute_motion): Use it. This is just for clarity.
18409 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18411 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18413 * lisp.h (lint_assume): New macro.
18414 * composite.c (composition_gstring_put_cache):
18415 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18417 * editfns.c, insdel.c:
18418 Omit unnecessary forward decls, to simplify future changes.
18420 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18422 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18424 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18425 Use much-faster test for byte-length change.
18426 Don't assume string byte-length fits in 'int'.
18427 Check that character arg fits in 'int'.
18428 (mapcar1): Declare byte as byte, for clarity.
18430 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18432 * fns.c (concat): Catch string overflow earlier.
18433 Do not rely on integer wraparound.
18435 * dispextern.h (struct it.overlay_strings_charpos)
18436 (struct it.selective): Now EMACS_INT, not int.
18437 * xdisp.c (forward_to_next_line_start)
18438 (back_to_previous_visible_line_start)
18439 (reseat_at_next_visible_line_start, next_element_from_buffer):
18440 Don't arbitrarily truncate the value of 'selective' to int.
18442 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18444 * composite.c: Don't truncate sizes to 'int'.
18445 (composition_gstring_p, composition_reseat_it)
18446 (composition_adjust_point): Use EMACS_INT, not int.
18447 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18448 not EMACS_UINT, for indexes.
18450 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18452 * buffer.c: Include <verify.h>.
18453 (struct sortvec.priority, struct sortstr.priority):
18454 Now EMACS_INT, not int.
18455 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18456 (struct sortstr.size, record_overlay_string)
18457 (struct sortstrlist.size, struct sortlist.used):
18458 Don't truncate size to int.
18459 (record_overlay_string): Check for size-calculation overflow.
18460 (init_buffer_once): Check at compile-time, not run-time.
18462 2011-06-22 Jim Meyering <meyering@redhat.com>
18464 Don't leak an XBM-image-sized buffer
18465 * image.c (xbm_load): Free the image buffer after using it.
18467 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18470 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18471 that Sun C diagnosed.
18472 * fns.c (secure_hash): Fix pointer signedness issue.
18473 * intervals.c (static_offset_intervals): New function.
18474 (offset_intervals): Use it.
18476 2011-06-21 Leo Liu <sdl.web@gmail.com>
18479 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18482 * fns.c (secure_hash): Rename from crypto_hash_function and change
18483 the first arg to accept symbols.
18484 (Fsecure_hash): New primitive.
18485 (syms_of_fns): New symbols.
18487 2011-06-20 Deniz Dogan <deniz@dogan.se>
18489 * process.c (Fset_process_buffer): Clarify return value in
18492 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18494 * dispnew.c (add_window_display_history): Use BVAR.
18496 * xdisp.c (debug_method_add): Use BVAR.
18497 (check_window_end, dump_glyph_matrix, dump_glyph)
18498 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18500 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18503 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18504 check till after the cache is created in init_frame_faces.
18506 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18508 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18510 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18512 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18513 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18514 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18516 Improve buffer-overflow checking (Bug#8873).
18517 * fileio.c (Finsert_file_contents):
18518 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18519 Remove the old (too-loose) buffer overflow checks.
18520 They weren't needed, since make_gap checks for buffer overflow.
18521 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18522 The old code merely checked for Emacs fixnum overflow, and relied
18523 on undefined (wraparound) behavior. The new code avoids undefined
18524 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18526 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18527 Tune. Don't use wider integers than needed. Don't use alloca.
18528 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18530 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18532 * insdel.c, lisp.h (buffer_overflow): New function.
18533 (insert_from_buffer_1, replace_range, replace_range_2):
18534 * insdel.c (make_gap_larger):
18535 * editfns.c (Finsert_char):
18536 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18538 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18540 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18542 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18544 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18545 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18547 * fileio.c: Don't assume EMACS_INT fits in off_t.
18548 (emacs_lseek): New static function.
18549 (Finsert_file_contents, Fwrite_region): Use it.
18550 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18552 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18554 * fns.c: Don't overflow int when computing a list length.
18555 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18556 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18557 truncation on 64-bit hosts. Check for QUIT every
18558 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18559 faster and is responsive enough.
18560 (Flength): Report an error instead of overflowing an integer.
18561 (Fsafe_length): Return a float if the value is not representable
18562 as a fixnum. This shouldn't happen except in contrived situations.
18563 (Fnthcdr, Fsort): Don't assume list length fits in int.
18564 (Fcopy_sequence): Don't assume vector length fits in int.
18566 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18567 (header_size, word_size): New constants.
18568 (allocate_vectorlike): Don't check size overflow here.
18569 (allocate_vector): Check it here instead, since this is the only
18570 caller of allocate_vectorlike that could cause overflow.
18571 Check that the new vector's length is representable as a fixnum.
18573 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18574 The previous code was bogus. For example, next_almost_prime (32)
18575 returned 39, which is undesirable as it is a multiple of 3; and
18576 next_almost_prime (24) returned 25, which is a multiple of 5 so
18577 why was the code bothering to check for multiples of 7?
18579 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18581 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18583 Variadic C functions now count arguments with ptrdiff_t.
18584 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18585 Back then I didn't know that the Emacs coding style prefers signed int.
18586 Also, in the meantime I found a few more instances where arguments
18587 were being counted with int, which may truncate counts on 64-bit
18588 machines, or EMACS_INT, which may be unnecessarily wide.
18589 * lisp.h (struct Lisp_Subr.function.aMANY)
18590 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18591 Arg counts are now ptrdiff_t, not size_t.
18592 All variadic functions and their callers changed accordingly.
18593 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18594 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18595 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18596 * callint.c (Fcall_interactively): Check arg count for overflow,
18597 to avoid potential buffer overrun. Use signed char, not 'int',
18598 for 'varies' array, so that we needn't bother to check its size
18599 calculation for overflow.
18600 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18601 * eval.c (apply_lambda):
18602 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18603 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18604 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18606 * callint.c (Fcall_interactively): Don't use index var as event count.
18608 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18609 * mem-limits.h (SIZE): Remove; no longer used.
18611 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18613 Remove unnecessary casts.
18614 * xterm.c (x_term_init):
18615 * xfns.c (x_set_border_pixel):
18616 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18617 These aren't needed now that we assume ANSI C.
18619 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18620 It's more likely to cause problems (due to unsigned overflow)
18623 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18625 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18627 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18629 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18631 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18633 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18635 GLYPH_CODE_FACE returns EMACS_INT, not int.
18636 * dispextern.h (merge_faces):
18637 * xfaces.c (merge_faces):
18638 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18639 Don't assume EMACS_INT fits in int.
18641 * character.h (CHAR_VALID_P): Remove unused parameter.
18642 * fontset.c, lisp.h, xdisp.c: All uses changed.
18644 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18646 * fns.c (concat): Minor tuning based on overflow analysis.
18647 This doesn't fix any bugs. Use int to hold character, instead
18648 of constantly refetching from Emacs object. Use XFASTINT, not
18649 XINT, for value known to be a character. Don't bother comparing
18650 a single byte to 0400, as it's always less.
18652 * floatfns.c (Fexpt):
18653 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18655 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18658 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18660 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18661 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18662 incorrectly succeed when S was a string, because 4294967386 was
18663 truncated before it was used.
18665 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18666 Otherwise, an out-of-range integer could cause undefined behavior
18669 * composite.c: Use int, not EMACS_INT, for characters.
18670 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18671 EMACS_INT, for values that are known to be in character range.
18672 This doesn't fix any bugs but is the usual style inside Emacs and
18673 may generate better code on 32-bit machines.
18675 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18676 This is for reasons similar to the recent CHAR_STRING fix.
18677 * charset.c (Fencode_char): Check that character arg is actually
18678 a character. Pass an int to ENCODE_CHAR.
18679 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18680 wider than 'int', as a compile-time check to prevent future regressions
18683 * character.c (char_string): Remove unnecessary casts.
18685 Make sure a 64-bit char is never passed to CHAR_STRING.
18686 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18687 by silently ignoring the top 32 bits, allowing some values
18688 that were far too large to be valid characters.
18689 * character.h: Include <verify.h>.
18690 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18691 arguments are no wider than unsigned, as a compile-time check
18692 to prevent future regressions in this area.
18694 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18695 (Fsubst_char_in_region):
18697 * xdisp.c (decode_mode_spec_coding):
18698 Adjust to CHAR_STRING's new requirement.
18699 * editfns.c (Finsert_char, Fsubst_char_in_region):
18700 * fns.c (concat): Check that character args are actually
18701 characters. Without this test, these functions did the wrong
18702 thing with wildly out-of-range values on 64-bit hosts.
18704 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18705 These casts should not be needed on 32-bit hosts, either.
18706 * keyboard.c (read_char):
18707 * lread.c (Fload): Remove casts to unsigned.
18709 * lisp.h (UNSIGNED_CMP): New macro.
18710 This fixes comparison bugs on 64-bit hosts.
18711 (ASCII_CHAR_P): Use it.
18712 * casefiddle.c (casify_object):
18713 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18714 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18715 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18716 * dispextern.h (FACE_FROM_ID):
18717 * keyboard.c (read_char): Use UNSIGNED_CMP.
18719 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18720 not to EMACS_INT, to avoid GCC warning.
18722 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18724 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18725 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18726 isn't needed on 32-bit machines.
18728 * buffer.c (Fgenerate_new_buffer_name):
18729 Use EMACS_INT for count, not int.
18730 (advance_to_char_boundary): Return EMACS_INT, not int.
18732 * data.c (Qcompiled_function): Now static.
18734 * window.c (window_body_lines): Now static.
18736 * image.c (gif_load): Rename local to avoid shadowing.
18738 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18739 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18740 * alloc.c (make_save_value): Integer argument is now of type
18741 ptrdiff_t, not int.
18742 (mark_object): Use ptrdiff_t, not int.
18743 * lisp.h (pD): New macro.
18744 * print.c (print_object): Use it.
18746 * alloc.c: Use EMACS_INT, not int, to count objects.

18748 (total_free_conses, total_free_markers, total_free_symbols)
18749 (total_free_floats, total_floats, total_free_intervals)
18750 (total_intervals, total_strings, total_free_strings):
18751 Now EMACS_INT, not int. All uses changed.
18752 (Fgarbage_collect): Compute overall total using a double, so that
18753 integer overflow is less likely to be a problem. Check for overflow
18754 when converting back to an integer.
18755 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18756 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18757 These were 'int' variables that could overflow on 64-bit hosts;
18758 they were never used, so remove them instead of repairing them.
18759 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18760 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18761 Previously, this ceilinged at INT_MAX, but that doesn't work on
18763 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18765 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18766 (allocate_vectorlike): Check for ptrdiff_t overflow.
18767 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18768 when a (possibly-narrower) signed value would do just as well.
18769 We prefer using signed arithmetic, to avoid comparison confusion.
18771 * alloc.c: Catch some string size overflows that we were missing.
18772 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18773 for convenience in STRING_BYTES_MAX.
18774 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18775 The definition here is exact; the one in lisp.h was approximate.
18776 (allocate_string_data): Check for string overflow. This catches
18777 some instances we weren't catching before. Also, it catches
18778 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18779 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18780 and ptrdiff_t and EMACS_INT are both 64 bits.
18782 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18783 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18784 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18786 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18788 * alloc.c (Fmake_string): Check for out-of-range init.
18790 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18792 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.

18814 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18816 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

19361 instead of using explicit *_CHAR codes.
19362 (bidi_resolve_explicit, bidi_resolve_weak):

19371 (bidi_level_of_next_char): Don't try to lookup the cache for the
19372 next/previous character if nothing is cached there yet, or if we
19373 were just reseat()'ed to a new position.
19375 * xdisp.c (set_cursor_from_row): Set start and stop points
19376 according to the row's direction when priming the loop that looks
19377 for the glyph on which to display cursor.

19379 (display_prop_intangible_p): Reimplement to call
19380 handle_display_spec instead of single_display_spec_intangible_p.
19381 Accept 3 additional arguments needed by handle_display_spec.
19382 This fixes incorrect cursor motion across display property with complex
19383 values: lists, `(when COND...)' forms, etc.

19391 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19392 value of a `display' property is a "replacing spec".
19393 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19394 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19395 the display property, but just return a value indicating whether
19396 the display property will replace the characters it covers.
19397 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19398 frame_window_p members of struct bidi_it.
19399 (compute_display_string_pos, compute_display_string_end):

19422 All callers changed. (Bug#8762)
19424 * gnutls.c: Use Emacs's memory allocators.
19425 Without this change, the gnutls library would invoke malloc etc.
19426 directly, which causes problems on non-SYNC_INPUT hosts, and which
19427 runs afoul of improving memory_full behavior. (Bug#8761)
19428 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19429 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19430 xfree instead of the default malloc, realloc, free.
19431 (Fgnutls_boot): No need to check for memory allocation failure,
19432 since xmalloc does that for us.
19434 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

19454 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19455 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19456 * alloc.c (allocate_vectorlike):
19457 Check for overflow in vector size calculations.
19458 * ccl.c (ccl_driver):
19459 Check for overflow when converting EMACS_INT to int.

19461 need to be updated by these changes.
19462 * fns.c (make_hash_table, maybe_resize_hash_table):
19463 Check for integer overflow with large hash tables.
19464 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19465 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19466 (SXHASH_REDUCE): New macro.
19467 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19468 Use it instead of discarding useful hash info with large hash values.
19469 (sxhash_float): New function.
19470 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19471 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19472 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19473 Rewrite to use FIXNUM_BITS, as this simplifies things.
19474 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19475 Adjust signatures to match updated version of code.
19476 (consing_since_gc): Now EMACS_INT, since a single hash table can
19477 use more than INT_MAX bytes.

19526 Make it possible to run ./temacs.
19528 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19529 syms_of_callproc does the same thing. Remove test for
19530 "initialized", do it in the caller.
19531 * emacs.c (main): Avoid calling set_initial_environment when dumping.

19552 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19553 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19554 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19556 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19558 * image.c: Various fixes to ImageMagick code comments.
19559 (Fimagemagick_types): Doc fix.
19561 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19563 Minor fixes prompted by GCC 4.6.0 warnings.
19565 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19567 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19568 (x_clipboard_manager_save_all): Move extern decl to ...
19569 * xterm.h: ... here, so that it can be checked for consistency.
19571 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19573 * xselect.c (x_clipboard_manager_save_frame)
19574 (x_clipboard_manager_save_all): New functions.
19575 (Fx_clipboard_manager_save): Lisp function deleted.
19577 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19578 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19580 * xterm.h: Update prototype.
19582 2011-05-28 William Xu <william.xwl@gmail.com>
19584 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19585 exiting (Bug#8239).
19587 2011-05-28 Jim Meyering <meyering@redhat.com>
19589 Avoid a sign-extension bug in crypto_hash_function.
19590 * fns.c (to_uchar): Define.
19591 (crypto_hash_function): Use it to convert some newly-signed
19592 variables to unsigned, to avoid sign-extension bugs. For example,
19593 without this change, (md5 "truc") would evaluate to
19594 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19595 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19596 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19598 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19600 Integer overflow fixes.
19602 * dbusbind.c: Serial number integer overflow fixes.
19603 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19604 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19605 to hold a serial number that is too large for a fixnum.
19606 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19607 Check for serial numbers out of range. Decode any serial number
19608 that was so large that it became a float. (Bug#8722)
19610 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19611 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19612 Use XFASTINT rather than XUINT when numbers are nonnegative.
19613 (xd_append_arg, Fdbus_method_return_internal):
19614 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19615 arguments, check that Lisp number is nonnegative, rather than
19616 silently wrapping negative numbers around. (Bug#8722)
19617 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19620 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19622 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19624 ccl: Add integer overflow checks.
19625 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19626 (IN_INT_RANGE): New macros.
19627 (ccl_driver): Use them to check for integer overflow when
19628 decoding a CCL program. Many of the new checks are whether XINT (x)
19629 fits in int; it doesn't always, on 64-bit hosts. The new version
19630 doesn't catch all possible integer overflows, but it's an
19631 improvement. (Bug#8719)
19633 * alloc.c (make_event_array): Use XINT, not XUINT.
19634 There's no need for unsigned here.
19636 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19637 This follows up to the 2011-05-06 change that substituted uintptr_t
19638 for EMACS_INT. This case wasn't caught back then.
19640 Rework Fformat to avoid integer overflow issues.
19641 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19642 now (part of C89). Include <verify.h>.
19643 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19644 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19645 (Fformat): Avoid the prepass trying to compute sizes; it was only
19646 approximate and thus did not catch overflow reliably. Instead, walk
19647 through the format just once, formatting and computing sizes as we go,
19648 checking for integer overflow at every step, and allocating a larger
19649 buffer as needed. Keep track separately whether the format is
19650 multibyte. Keep only the most-recently calculated precision, rather
19651 than them all. Record whether each argument has been converted to
19652 string. Use EMACS_INT, not int, for byte and char and arg counts.
19653 Support field widths and precisions larger than INT_MAX. Avoid
19654 sprintf's undefined behavior with conversion specifications such as %#d
19655 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19656 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19657 formatting out-of-range floating point numbers with int
19658 formats. (Bug#8668)
19660 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19662 * data.c: Avoid integer truncation in expressions involving floats.
19663 * data.c: Include <intprops.h>.
19664 (arith_driver): When there's an integer overflow in an expression
19665 involving floating point, convert the integers to floating point
19666 so that the resulting value does not suffer from catastrophic
19667 integer truncation. For example, on a 64-bit host (* 4
19668 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19669 Do not rely on undefined behavior after integer overflow.
19671 merge count_size_as_multibyte, parse_str_to_multibyte
19672 * character.c, character.h (count_size_as_multibyte):
19673 Rename from parse_str_to_multibyte; all uses changed.
19674 Check for integer overflow.
19675 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19676 since it's now a duplicate of the other. This is more of
19677 a character than a buffer op, so better that it's in character.c.
19678 * fns.c, print.c: Adjust to above changes.
19680 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19682 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19684 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19686 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19687 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19688 (x_clipboard_manager_save): Now static.
19689 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19691 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19692 (crypto_hash_function): Now static.
19693 Fix pointer signedness problems. Avoid unnecessary initializations.
19695 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19697 * termhooks.h (Vselection_alist): Make it terminal-local.
19699 * terminal.c (create_terminal): Initialize it.
19701 * xselect.c: Support for clipboard managers.
19702 (Vselection_alist): Move to termhooks.h as terminal-local var.
19703 (LOCAL_SELECTION): New macro.
19704 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19705 (symbol_to_x_atom): Remove gratuitous arg.
19706 (x_handle_selection_request, lisp_data_to_selection_data)
19707 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19708 (x_own_selection, x_get_local_selection, x_convert_selection):
19709 New arg, specifying work frame. Use terminal-local Vselection_alist.
19710 (some_frame_on_display): Delete unused function.
19711 (Fx_own_selection_internal, Fx_get_selection_internal)
19712 (Fx_disown_selection_internal, Fx_selection_owner_p)
19713 (Fx_selection_exists_p): New optional frame arg.
19714 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19715 (x_handle_selection_clear): Don't treat other terminals with the
19716 same keyboard specially. Use the terminal-local Vselection_alist.
19717 (x_clear_frame_selections): Use Frun_hook_with_args.
19719 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19721 * xterm.h: Add support for those atoms.
19723 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19725 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19726 (converted_selections, conversion_fail_tag): New global variables.
19727 (x_selection_request_lisp_error): Free the above.
19728 (x_get_local_selection): Remove unnecessary code.
19729 (x_reply_selection_request): Args changed; handle arbitrary array
19730 of converted selections stored in converted_selections.
19731 Separate the XChangeProperty and SelectionNotify steps.
19732 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19733 (x_convert_selection): New function.
19734 (x_handle_selection_event): Simplify.
19735 (x_get_foreign_selection): Don't ignore incoming requests while
19736 waiting for an answer; this will fail when we implement
19737 SAVE_TARGETS, and seems unnecessary anyway.
19738 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19739 (Vx_sent_selection_functions): Doc fix.
19741 2011-05-26 Leo Liu <sdl.web@gmail.com>
19743 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19745 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19747 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19749 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19750 for fringe update if it has periodic bitmap.
19751 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19752 and fringe_bitmap_periodic_p.
19754 * fringe.c (get_fringe_bitmap_data): New function.
19755 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19756 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19757 row. Mark glyph row for fringe update if periodicity changed.
19759 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19760 for fringe update unless it has periodic bitmap.
19762 2011-05-25 Kenichi Handa <handa@m17n.org>
19764 * xdisp.c (get_next_display_element): Set correct it->face_id for
19765 a static composition.
19767 2011-05-24 Leo Liu <sdl.web@gmail.com>
19770 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19772 * fns.c (crypto_hash_function, Fsha1): New function.
19773 (Fmd5): Use crypto_hash_function.
19774 (syms_of_fns): Add Ssha1.
19776 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19778 * gnutls.c: Remove unused macros.
19779 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19780 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19781 Remove macros that are defined and never used.
19782 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19784 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19786 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19787 (Fx_get_selection_internal): Minor cleanup.
19788 (Fx_own_selection_internal): Rename arguments for consistency with
19791 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19793 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19795 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19797 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19799 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19801 * dispnew.c (scrolling_window): Don't exclude the case that the
19802 last enabled row in the desired matrix touches the bottom boundary.
19804 2011-05-21 Glenn Morris <rgm@gnu.org>
19806 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19807 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19808 and add some more files.
19810 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19812 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19813 report_file_error introduced by the change from 2011-05-07.
19815 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19817 * systime.h (Time): Define only if emacs is defined.
19818 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19819 where the include path doesn't have X11/X.h by default. See
19820 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19822 2011-05-20 Kenichi Handa <handa@m17n.org>
19824 * composite.c (find_automatic_composition): Fix previous change.
19826 2011-05-20 Glenn Morris <rgm@gnu.org>
19828 * lisp.mk: New file, split from Makefile.in.
19829 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19830 (shortlisp): Remove.
19831 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19833 2011-05-19 Glenn Morris <rgm@gnu.org>
19835 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19836 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19837 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19838 (lisp): Set the order to that of loadup.el.
19839 (shortlisp): Make it a copy of $lisp.
19840 (SOME_MACHINE_LISP): Remove.
19841 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19842 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19844 2011-05-18 Kenichi Handa <handa@m17n.org>
19846 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19847 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19848 (find_automatic_composition): Mostly rewrite for efficiency.
19850 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19852 * makefile.w32-in: Update dependencies.
19854 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19856 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19857 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19859 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19861 Fix some integer overflow issues, such as string length overflow.
19863 * insdel.c (count_size_as_multibyte): Check for string overflow.
19865 * character.c (lisp_string_width): Check for string overflow.
19866 Use EMACS_INT, not int, for string indexes and lengths; in
19867 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19868 the resulting string length overflows an EMACS_INT; instead,
19869 report a string overflow if no precision given. When checking for
19870 precision exhaustion, use a check that cannot possibly have
19871 integer overflow. (Bug#8675)
19872 * character.h (lisp_string_width): Adjust to new signature.
19874 * alloc.c (string_overflow): New function.
19875 (Fmake_string): Use it. This doesn't change behavior, but saves
19876 a few bytes and will simplify future changes.
19877 * character.c (string_escape_byte8): Likewise.
19878 * lisp.h (string_overflow): New decl.
19880 Fixups, following up to the user-interface timestamp change.
19881 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19882 for UI timestamps, instead of unsigned long.
19883 * msdos.c (mouse_get_pos): Likewise.
19884 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19885 * w32gui.h (Time): Define by including "systime.h" rather than by
19886 declaring it ourselves. (Bug#8664)
19888 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19889 * image.c (clear_image_cache): Likewise.
19891 * term.c (term_mouse_position): Don't assume time_t wraparound.
19893 Be more systematic about user-interface timestamps.
19894 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19895 and sometimes 'EMACS_UINT', to represent these timestamps.
19896 This change causes it to use 'Time' uniformly, as that's what X uses.
19897 This makes the code easier to follow, and makes it easier to catch
19898 integer overflow bugs such as Bug#8664.
19899 * frame.c (Fmouse_position, Fmouse_pixel_position):
19900 Use Time, not unsigned long, for user-interface timestamps.
19901 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19902 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19903 * keyboard.h (last_event_timestamp): Likewise.
19904 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19905 * menu.h (xmenu_show): Likewise.
19906 * term.c (term_mouse_position): Likewise.
19907 * termhooks.h (struct input_event.timestamp): Likewise.
19908 (struct terminal.mouse_position_hook): Likewise.
19909 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19910 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19911 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19912 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19913 what it was before.
19914 * menu.h, termhooks.h: Include "systime.h", for Time.
19916 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19917 Don't assume that the difference between two unsigned long values
19918 can fit into an integer. At this point, we know button_down_time
19919 <= event->timestamp, so the difference must be nonnegative, so
19920 there's no need to cast the result if double-click-time is
19921 nonnegative, as it should be; check that it's nonnegative, just in
19922 case. This bug is triggered when events are more than 2**31 ms
19923 apart (about 25 days). (Bug#8664)
19925 * xselect.c (last_event_timestamp): Remove duplicate decl.
19926 (x_own_selection): Remove needless cast to unsigned long.
19928 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19929 that always fit in int. Use a sentinel instead of a counter, to
19930 avoid a temp and to allay GCC's concerns about possible int overflow.
19931 * frame.h (struct frame): Use int for menu_bar_items_used
19932 instead of EMACS_INT, since it always fits in int.
19934 * menu.c (grow_menu_items): Check for int overflow.
19936 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19938 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19939 Before, the code was not consistent. These values cannot exceed
19940 2**31 - 1 so there's no need to make them unsigned.
19941 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19942 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19943 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19945 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19947 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19948 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19949 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19950 presumably because the widths might not match.
19952 * window.c (size_window): Avoid needless test at loop start.
19954 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19956 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19958 2011-05-12 Drew Adams <drew.adams@oracle.com>
19960 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19962 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19964 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19965 `width' to `bar_area_x' and `bar_area_width', respectively.
19966 (x_scroll_run): Take account of fringe background extension.
19968 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19969 Rename local vars `left' and `width' to `bar_area_x' and
19970 `bar_area_width', respectively.
19971 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19972 background extension.
19974 2011-05-10 Jim Meyering <meyering@redhat.com>
19976 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19978 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19980 * image.c (Finit_image_library): Return t for built-in image types,
19981 like pbm and xbm. (Bug#8640)
19983 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19985 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19987 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19989 * w32console.c (Fset_screen_color): Doc fix.
19990 (Fget_screen_color): New function.
19991 (syms_of_ntterm): Defsubr it.
19993 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19994 unlink the temporary file if Fcall_process didn't create it in the
19996 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19997 child process will be redirected to a file specified with `:file'.
19998 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19999 cue to call_process_cleanup not to close that handle.
20001 2011-05-07 Ben Key <bkey76@gmail.com>
20003 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20004 one of two shell specific rules, either bootstrap-temacs-CMD or
20005 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20006 to the previous implementation of the bootstrap-temacs rule.
20007 The bootstrap-temacs-CMD rule is similar to the previous
20008 implementation of the bootstrap-temacs rule except that it
20009 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20012 These changes, along with some changes to nt/configure.bat,
20013 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20014 earlier fix to add support for --cflags and --ldflags options
20015 that include quotes so that it works whether make uses cmd or
20018 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20020 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20021 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20023 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20024 a string. Handle both cases.
20025 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20026 (Fdbus_register_method): Use Qinvalid_function.
20028 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20030 * makefile.w32-in: Update dependencies.
20031 (LISP_H): Add inttypes.h and stdin.h.
20032 (PROCESS_H): Add unistd.h.
20034 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20036 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20037 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20039 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20041 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20043 * term.c (vfatal): Remove stray call to va_end.
20044 It's not needed and the C Standard doesn't allow it here anyway.
20046 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20047 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20049 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20052 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20054 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20056 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20058 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20060 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20062 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20063 * charset.c (Fdefine_charset_internal): Don't initialize
20064 charset.code_space[15]. The value was garbage, on hosts with
20065 32-bit int (Bug#8600).
20067 * lread.c (read_integer): Be more consistent with string-to-number.
20068 Use string_to_number to do the actual conversion; this avoids
20069 rounding errors and fixes some other screwups. Without this fix,
20070 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20071 (digit_to_number): Move earlier, for benefit of read_integer.
20072 Return -1 if the digit is out of range for the base, -2 if it is
20073 not a digit in any supported base. (Bug#8602)
20075 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20077 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20078 to match comment at start of function. This also removes a
20079 GCC warning about overflow in a 32+64-bit port.
20081 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20083 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20084 Reported by Stefan Monnier in
20085 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20086 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20087 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20089 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20090 (EMACS_UINTPTR): Likewise, with uintptr_t.
20092 * lisp.h: Prefer 64-bit EMACS_INT if available.
20093 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20094 on 32-bit hosts that have 64-bit int, so that they can access
20096 However, temporarily disable this change unless the temporary
20097 symbol WIDE_EMACS_INT is defined.
20099 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20101 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20102 This removes an assumption that EMACS_INT and long are the same
20103 width as pointers. The assumption is true for Emacs porting targets
20104 now, but we want to make other targets possible.
20105 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20106 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20107 In the rest of the code, change types of integers that hold casted
20108 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20109 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20110 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20111 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20112 No need to cast type when ORing.
20113 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20114 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20115 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20116 assume EMACS_INT is the same width as char *.
20117 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20118 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20119 Remove no-longer-needed casts.
20120 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20121 (xg_tool_bar_help_callback, xg_make_tool_item):
20122 Use EMACS_INTPTR to hold an integer
20123 that will be cast to void *; this can avoid a GCC warning
20124 if EMACS_INT is not the same width as void *.
20125 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20126 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20127 (current_message_1, set_message_1):
20128 Use a local to convert to proper width without a cast.
20129 * xmenu.c (dialog_selection_callback): Likewise.
20131 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20132 Also, don't assume VALBITS / RAND_BITS is less than 5,
20133 and don't rely on undefined behavior when shifting a 1 left into
20135 * lisp.h (get_random): Change signature to match.
20137 * lread.c (hash_string): Use size_t, not int, for hash computation.
20138 Normally we prefer signed values; but hashing is special, because
20139 it's better to use unsigned division on hash table sizes so that
20140 the remainder is nonnegative. Also, size_t is the natural width
20141 for hashing into memory. The previous code used 'int', which doesn't
20142 retain enough info to hash well into very large tables.
20143 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20145 * dbusbind.c: Don't possibly lose pointer info when converting.
20146 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20147 Use XPNTR rather than XHASH, so that the high-order bits of
20148 the pointer aren't lost when converting through void *.
20150 * eval.c (Fautoload): Don't double-shift a pointer.
20152 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20154 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20156 * gnutls.c (DEF_GNUTLS_FN):
20157 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20159 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20161 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20164 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20166 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20167 New version that can reserve upto 2GB of heap space.
20169 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20171 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20173 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20175 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20176 `gnutls_certificate_set_x509_key_file'.
20178 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20180 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20181 Update dependencies.
20183 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20185 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20186 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20187 Remove unused parameter `fildes'.
20188 * process.c (read_process_output, send_process): Don't pass it.
20190 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20192 Fix previous change: the library cache is defined in w32.c.
20193 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20194 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20196 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20198 Implement dynamic loading of GnuTLS on Windows.
20200 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20201 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20202 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20205 * gnutls.c (Qgnutls_dll): Define.
20206 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
20207 (gnutls_*): Declare function pointers.
20208 (init_gnutls_functions): New function to initialize function pointers.

20210 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
20211 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20212 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
20213 (emacs_gnutls_write, emacs_gnutls_read)
20214 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20215 (Fgnutls_available_p): New function.
20216 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
20217 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
20218 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
20220 * image.c: Include w32.h.
20221 (Vimage_type_cache): Delete.

20224 (w32_delayed_load): Move to w32.c.
20226 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20228 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20229 (w32_delayed_load): Move from image.c. When loading a library, record
20230 its filename in the :loaded-from property of the library id.
20231 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20232 Initialize and staticpro them.
20233 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20235 * process.c: Include lisp.h before w32.h, not after.
20236 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20237 instead of gnutls_record_check_pending.
20239 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20241 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20243 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20244 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20247 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20249 * xterm.c (x_set_frame_alpha): Do not set property on anything
20250 else than FRAME_X_OUTER_WINDOW (Bug#8608).
20252 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20254 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
20256 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20258 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

20272 * sysdep.c (wait_for_termination_1): Make static.
20273 (wait_for_termination, interruptible_wait_for_termination):
20274 Move after wait_for_termination_1.
20276 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
20278 * sysdep.c (interruptible_wait_for_termination): New function
20279 which is like wait_for_termination, but allows keyboard
20282 * callproc.c (Fcall_process): Add (:file "file") as an option for
20284 (Fcall_process_region): Ditto.
20286 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20288 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20289 rather than `XVECTOR (FOO)->size'.
20291 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20292 inttypes.h, as a gnulib replacement is used if it not available in
20295 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20297 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20298 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20299 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20301 * coding.c (coding_alloc_by_realloc): Error out if destination
20302 will grow beyond MOST_POSITIVE_FIXNUM.
20303 (decode_coding_emacs_mule): Abort if there isn't enough place in
20304 charbuf for the composition carryover bytes. Reserve an extra
20305 space for up to 2 characters produced in a loop.
20306 (decode_coding_iso_2022): Abort if there isn't enough place in
20307 charbuf for the composition carryover bytes.

20312 aborting when %lld or %lll format is passed.
20313 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20314 %llo or %llx format is passed. (Bug#8545)
20316 * window.c (window_scroll_line_based): Use a marker instead of
20317 simple variables to record original value of point. (Bug#7952)
20319 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20320 produced by %s or %c overflows available buffer space. (Bug#8545)
20322 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20324 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20325 (SIZE_MAX): Move defn after all includes, as they might #define it.
20327 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20329 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20331 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20333 * keyboard.c (Qdelayed_warnings_hook): Define.
20334 (command_loop_1): Run `delayed-warnings-hook'
20335 if Vdelayed_warnings_list is non-nil.
20336 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.

20339 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20341 * doprnt.c (doprnt): Don't return value smaller than the buffer
20342 size if the message was truncated. (Bug#8545).

20349 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20351 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20353 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20355 * makefile.w32-in: Update dependencies.
20357 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20359 Improve `doprnt' and its usage. (Bug#8545)
20360 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20361 `format_end'. Remove support for %l as a conversion specifier.
20362 Don't use xrealloc. Improve diagnostics when the %l size modifier
20363 is used. Update the commentary.
20365 * eval.c (verror): Simplify calculation of size_t.
20367 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20370 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20372 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20375 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20377 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20378 This makes this file independent of the recent pseudovector change.
20380 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20382 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20384 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20385 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20386 Remove unused local.
20387 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20389 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20390 GCC 4.6.0 optimizes based on type-based alias analysis.
20391 For example, if b is of type struct buffer * and v of type struct
20392 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20393 != &v->size, and therefore "v->size = 1; b->size = 2; return
20394 v->size;" must therefore return 1. This assumption is incorrect
20395 for Emacs, since it type-puns struct Lisp_Vector * with many other
20396 types. To fix this problem, this patch adds a new type struct
20397 vectorlike_header that documents the constraints on layout of vectors
20398 and pseudovectors, and helps optimizing compilers not get fooled
20399 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20400 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20401 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20403 (XSETPVECTYPE): Rewrite in terms of new macro.
20404 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20405 This is a bit clearer, and further avoids the possibility of
20406 undesirable aliasing.
20407 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20408 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20409 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20410 since Lisp_Subr is a special case (no "next" field).
20411 (ASIZE): Now uses header.size rather than size.
20412 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20413 to avoid the hassle of writing XVECTOR (foo)->header.size.
20414 (struct vectorlike_header): New type.
20415 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20416 object, to help avoid aliasing.
20417 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20418 (SUBRP): Likewise, since Lisp_Subr is a special case.
20419 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20420 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20421 (struct Lisp_Hash_Table): Combine first two members into a single
20422 struct vectorlike_header member. All uses of "size" and "next" members
20423 changed to be "header.size" and "header.next".
20424 * buffer.h (struct buffer): Likewise.
20425 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20426 * frame.h (struct frame): Likewise.
20427 * process.h (struct Lisp_Process): Likewise.
20428 * termhooks.h (struct terminal): Likewise.
20429 * window.c (struct save_window_data, struct saved_window): Likewise.
20430 * window.h (struct window): Likewise.
20431 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20432 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20433 * buffer.c (init_buffer_once): Likewise.
20434 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20436 * process.c (Fformat_network_address): Use local var for size,
20439 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20441 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20442 * data.c (atof): Remove decl; no longer used or needed.
20443 (digit_to_number): Move to lread.c.
20444 (Fstring_to_number): Use new string_to_number function, to be
20445 consistent with how the Lisp reader treats infinities and NaNs.
20446 Do not assume that floating-point numbers represent EMACS_INT
20447 without losing information; this is not true on most 64-bit hosts.
20448 Avoid double-rounding errors, by insisting on integers when
20449 parsing non-base-10 numbers, as the documentation specifies.
20450 * lisp.h (string_to_number): New decl, replacing ...
20451 (isfloat_string): Remove.
20452 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20453 (read1): Do not accept +. and -. as integers; this
20454 appears to have been a coding error. Similarly, do not accept
20455 strings like +-1e0 as floating point numbers. Do not report
20456 overflow for integer overflows unless the base is not 10 which
20457 means we have no simple and reliable way to continue.
20458 Break out the floating-point parsing into a new
20459 function string_to_number, so that Fstring_to_number parses
20460 floating point numbers consistently with the Lisp reader.
20461 (digit_to_number): Move here from data.c. Make it static inline.
20462 (E_CHAR, EXP_INT): Remove, replacing with ...
20463 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20464 (string_to_number): New function, replacing isfloat_string.
20465 This function checks for valid syntax and produces the resulting
20466 Lisp float number too. Rework it so that string-to-number
20467 no longer mishandles examples like "1.0e+". Use strtoumax,
20468 so that overflow for non-base-10 numbers is reported only when
20469 there's no portable and simple way to convert to floating point.
20471 * textprop.c (set_text_properties_1): Rewrite for clarity,
20472 and to avoid GCC warning about integer overflow.
20474 * intervals.h (struct interval): Use EMACS_INT for members
20475 where EMACS_UINT might cause problems. See
20476 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20477 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20478 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20480 (offset_intervals): Tell GCC not to worry about length overflow
20481 when negating a negative length.
20483 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20484 (overrun_check_free): Likewise.
20486 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20487 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20490 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20491 (gnutls_make_error): Rename local to avoid shadowing.
20492 (gnutls_emacs_global_deinit): ifdef out; not used.
20493 (Fgnutls_boot): Use const for pointer to readonly storage.
20494 Comment out unused local. Fix pointer signedness problems.
20496 * lread.c (openp): Don't stuff size_t into an 'int'.
20497 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20498 about possible signed overflow.
20500 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20501 (GDK_KEY_g): Don't define if already defined.
20502 (xg_prepare_tooltip): Avoid pointer signedness problem.
20503 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20505 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20506 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20508 * xfns.c (Fx_window_property): Simplify a bit,
20509 to make a bit faster and to avoid GCC 4.6.0 warning.
20510 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20512 * fns.c (internal_equal): Don't assume size_t fits in int.
20514 * alloc.c (compact_small_strings): Tighten assertion a little.
20516 Replace pEd with more-general pI, and fix some printf arg casts.
20517 * lisp.h (pI): New macro, generalizing old pEd macro to other
20518 conversion specifiers. For example, use "...%"pI"d..." rather
20519 than "...%"pEd"...".
20520 (pEd): Remove. All uses replaced with similar uses of pI.
20521 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20522 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20523 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20524 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20525 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20526 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20527 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20529 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20530 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20531 * print.c (safe_debug_print, print_object): Likewise.
20532 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20534 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20535 avoiding the 0 flag, which is not portable.
20536 * process.c (Fmake_network_process): Use pI to avoid cast.
20537 * region-cache.c (pp_cache): Likewise.
20538 * xdisp.c (decode_mode_spec): Likewise.
20539 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20540 behavior on 64-bit hosts with printf arg.
20541 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20542 (x_stop_queuing_selection_requests): Likewise.
20543 (x_get_window_property): Don't truncate byte count to an 'int'
20546 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20547 here, since it parses constructs like leading '-' and spaces,
20548 which are not wanted; and it overflows with large numbers.
20549 Instead, simply match F[0-9]+, which is what is wanted anyway.
20551 * alloc.c: Remove unportable assumptions about struct layout.
20552 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20553 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20554 (allocate_vectorlike, make_pure_vector): Use the new macros,
20555 plus offsetof, to remove unportable assumptions about struct layout.
20556 These assumptions hold on all porting targets that I know of, but
20557 they are not guaranteed, they're easy to remove, and removing them
20558 makes further changes easier.
20560 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20561 This doesn't fix a bug but makes the code clearer.
20562 (string_overrun_cookie): Now const. Use initializers that
20563 don't formally overflow signed char, to avoid warnings.
20564 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20565 can cause Emacs to crash when string overrun checking is enabled.
20566 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20567 multiple of sizeof (EMACS_INT); it need not be, if
20568 alignof(EMACS_INT) < sizeof (EMACS_INT).
20569 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20571 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

20578 supposed to be handshaking. (Bug#8556)
20579 Reported by Paul Eggert <eggert@cs.ucla.edu>.
20581 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

20592 (check_string_free_list): Convert to standard C.
20594 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
20596 * w32.c (emacs_gnutls_push): Fix typo.
20598 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20600 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20601 "cast to pointer from integer of different size".
20603 Improve doprnt and its use in verror. (Bug#8545)
20604 * doprnt.c (doprnt): Document the set of format control sequences
20605 supported by the function. Use SAFE_ALLOCA instead of always
20608 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20609 is one byte too soon. Don't use xrealloc; instead xfree and
20612 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20614 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20617 * gnutls.c: Renamed global_initialized to
20618 gnutls_global_initialized. Added internals for the
20619 :verify-hostname-error, :verify-error, and :verify-flags
20620 parameters of `gnutls-boot' and documented those parameters in the
20621 docstring. Start callback support.
20622 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20623 unless a fatal error occurred. Call gnutls_alert_send_appropriate
20624 on error. Return error code.

20684 changes in globals.h immediately force recompilation.
20685 (TAGS): Depend on $(CURDIR)/m/intel386.h and
20686 $(CURDIR)/s/ms-w32.h.

20691 <char-direction-table>: Deleted.
20693 2011-04-23 Eli Zaretskii <eliz@gnu.org>
20695 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
20696 * doprnt.c: Include limits.h.
20697 (SIZE_MAX): New macro.
20698 (doprnt): Return a size_t value. 2nd arg is now size_t.
20699 Many local variables are now size_t instead of int or unsigned.
20700 Improve overflow protection. Support `l' modifier for integer
20701 conversions. Support %l conversion. Don't assume an EMACS_INT
20702 argument for integer conversions and for %c.
20704 * lisp.h (doprnt): Restore prototype.
20706 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
20707 $(SRC)/character.h.
20709 * Makefile.in (base_obj): Add back doprnt.o.
20711 * deps.mk (doprnt.o): Add back prerequisites.
20712 (callint.o): Depend on character.h.
20714 * eval.c (internal_lisp_condition_case): Include the handler
20715 representation in the error message.
20716 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
20717 when breaking from the loop.

20721 * callint.c (Fcall_interactively): When displaying error message
20722 about invalid control letter, pass the character's codepoint, not
20723 a pointer to its multibyte form. Improve display of the character
20724 in octal and display also its hex code.
20726 * character.c (char_string): Use %x to display the (unsigned)
20727 codepoint of an invalid character, to avoid displaying a bogus
20730 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
20731 `error', not SYMBOL_NAME itself.
20733 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
20734 character arguments to `error'.
20736 * charset.c (check_iso_charset_parameter): Fix incorrect argument
20737 to `error' in error message about FINAL_CHAR argument. Make sure
20738 FINAL_CHAR is a character, and use %c when it is passed as
20739 argument to `error'.

20803 Define only if needed.
20805 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
20806 by pacifying GCC about it. Maybe it's time to retire it?
20807 * xfaces.c (USG, __TIMEVAL__): Likewise.
20809 * dispextern.h (struct redisplay_interface): Rename param
20810 to avoid shadowing.
20811 * termhooks.h (struct terminal): Likewise.
20812 * xterm.c (xembed_send_message): Likewise.
20814 * insdel.c (make_gap_smaller): Define only if
20815 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
20817 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
20820 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
20821 so that we aren't warned about unused symbols.
20823 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
20825 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
20827 * xfns.c (x_real_positions): Mark locals as initialized.
20829 * xmenu.c (xmenu_show): Don't use uninitialized vars.
20831 * xterm.c: Fix problems found by static analysis with other toolkits.
20832 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
20833 (x_dispatch_event): Declare static if USE_GTK, and
20834 define if USE_GTK || USE_X_TOOLKIT.
20835 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
20836 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
20837 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
20838 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
20840 * xmenu.c (menu_help_callback): Pointer type fixes.
20841 Use const pointers when pointing at readonly data. Avoid pointer
20842 signedness clashes.

20857 * bitmaps: Change bitmaps from unsigned char back to the X11
20858 compatible char. Avoid the old compiler warnings about
20859 out-of-range initializers by using, for example, '\xab' rather
20862 * xgselect.c (xgselect_initialize): Check vs interface
20863 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

20933 --enable-checking=xmallocoverrun). xfree is now used to
20934 deallocate these memory blocks.

21305 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
21306 it's not optimized away by whole-program optimization.
21307 (message_enable_multibyte, free_misc): Remove.
21308 (catchlist, handlerlist, mark_backtrace):
21309 Declare only if BYTE_MARK_STACK.
21310 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
21311 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
21312 (message_enable_multibyte): Remove decl.
21313 (free_misc, interval_free_list, float_block, float_block_index):
21314 (n_float_blocks, float_free_list, cons_block, cons_block_index):
21315 (cons_free_list, last_marked_index):
21317 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
21318 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
21319 (mark_backtrace): Define only if BYTE_MARK_STACK.
21320 * xdisp.c (message_enable_multibyte): Now static.
21322 Declare Lisp_Object Q* variables to be 'static' if not exported.
21323 This makes it easier for human readers (and static analyzers)
21324 to see whether these variables are used from other modules.
21325 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
21326 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
21327 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
21328 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
21329 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
21330 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
21331 * xmenu.c, xselect.c:
21332 Declare Q* vars static if they are not used in other modules.
21333 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
21334 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
21335 Remove decls of unexported vars.
21336 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21338 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21340 Make Emacs functions such as Fatom 'static' by default.
21341 This makes it easier for human readers (and static analyzers)
21342 to see whether these functions can be called from other modules.
21343 DEFUN now defines a static function. To make the function external
21344 so that it can be used in other C modules, use the new macro DEFUE.
21345 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21346 (Finit_image_library):
21347 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21348 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21349 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21350 Remove decls, since these functions are now static.
21351 (Funintern, Fget_internal_run_time): New decls, since these functions
21352 were already external.
21354 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21355 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
21356 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
21357 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
21358 * keyboard.c, keymap.c, lread.c:
21359 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
21360 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
21361 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21362 Mark functions with DEFUE instead of DEFUN,
21363 if they are used in other modules.
21364 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21365 decls for now-static functions.
21366 * buffer.h (Fdelete_overlay): Remove decl.
21367 * callproc.c (Fgetenv_internal): Mark as internal.
21368 * composite.c (Fremove_list_of_text_properties): Remove decl.

21372 * doc.c (Fdocumntation_property): New forward static decl.
21373 * eval.c (Ffetch_bytecode): New forward static decl.
21374 (Funintern): Remove extern decl; now in .h file where it belongs.
21375 * fileio.c (Fmake_symbolic_link): New forward static decl.
21376 * image.c (Finit_image_library): New forward static decl.
21377 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21378 * intervals.h (Fprevious_property_change):
21379 (Fremove_list_of_text_properties): Remove decls.
21380 * keyboard.c (Fthis_command_keys): Remove decl.
21381 (Fcommand_execute): New forward static decl.
21382 * keymap.c (Flookup_key): New forward static decl.
21383 (Fcopy_keymap): Now static.
21384 * keymap.h (Flookup_key): Remove decl.
21385 * process.c (Fget_process): New forward static decl.
21386 (Fprocess_datagram_address): Mark as internal.
21387 * syntax.c (Fsyntax_table_p): New forward static decl.
21388 (skip_chars): Remove duplicate decl.

21390 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
21392 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
21393 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
21395 * editfns.c (Fformat): Remove unreachable code.
21397 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
21399 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21402 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21404 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21405 when at ZV. (Bug#8487)
21407 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21409 * charset.c (Fclear_charset_maps): Use xfree instead of free.
21411 * keyboard.c (parse_tool_bar_item): Likewise.
21412 * sound.c (sound_cleanup, alsa_close): Likewise.
21413 * termcap.c (tgetent): Likewise.
21414 * xfns.c (x_default_font_parameter): Likewise.
21415 * xsettings.c (read_and_apply_settings): Likewise.
21417 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21418 (overrun_check_free): Protoize.
21420 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21422 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21423 since callers should never pass a negative size.
21424 Change the signature to match that of plain 'read' and 'write'; see
21425 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21426 * lisp.h: Update prototypes of emacs_write and emacs_read.
21428 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21430 * xdisp.c (redisplay_window): Don't try to determine the character
21431 position of the scroll margin if the window start point w->startp
21432 is outside the buffer's accessible region. (Bug#8468)
21434 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21436 Fix write-region and its subroutines for buffers > 2GB.
21437 * fileio.c (a_write, e_write): Modify declaration of arguments and
21438 local variables to support buffers larger than 2GB.
21439 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21441 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21442 argument, local variables, and return value.
21444 * lisp.h: Update prototypes of emacs_write and emacs_read.
21446 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21448 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21450 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21452 Fix more problems found by GCC 4.6.0's static checks.
21454 * xdisp.c (vmessage): Use a better test for character truncation.
21456 * charset.c (load_charset_map): <, not <=, for optimization,
21457 and to avoid potential problems with integer overflow.
21458 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21459 * casetab.c (set_identity, shuffle): Likewise.
21460 * editfns.c (Fformat): Likewise.
21461 * syntax.c (skip_chars): Likewise.
21463 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21464 This also lets GCC 4.6.0 generate slightly better loop code.
21466 * callint.c (Fcall_interactively): <, not <=, for optimization.
21467 (Fcall_interactively): Count the number of arguments produced,
21468 not the number of arguments given. This is simpler and lets GCC
21469 4.6.0 generate slightly better code.
21471 * ftfont.c: Distingish more carefully between FcChar8 and char.
21472 The previous code passed unsigned char * to a functions like
21473 strlen and xstrcasecmp that expect char *, which does not
21474 conform to the C standard.
21475 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21476 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21477 char * when the C standard requires it.
21479 * keyboard.c (read_char): Remove unused var.
21481 * eval.c: Port to Windows vsnprintf (Bug#8435).
21482 Include <limits.h>.
21483 (SIZE_MAX): Define if the headers do not.
21484 (verror): Do not give up if vsnprintf returns a negative count.
21485 Instead, grow the buffer. This ports to Windows vsnprintf, which
21486 does not conform to C99. Problem reported by Eli Zaretskii.
21487 Also, simplify the allocation scheme, by avoiding the need for
21488 calling realloc, and removing the ALLOCATED variable.
21490 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21492 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21493 But keep the doprint source code for now, as we might revamp it
21494 and use it again (Bug#8435).
21495 * lisp.h (doprnt): Remove.
21496 * Makefile.in (base_obj): Remove doprnt.o.
21497 * deps.mk (doprnt.o): Remove.
21499 error: Print 32- and 64-bit integers portably (Bug#8435).
21500 Without this change, on typical 64-bit hosts error ("...%d...", N)
21501 was used to print both 32- and 64-bit integers N, which relied on
21502 undefined behavior.
21503 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21504 * lisp.h (error, verror): Mark as printf-like functions.
21505 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21506 Report overflow in size calculations when allocating printf buffer.
21507 Do not truncate output string at its first null byte.
21508 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21509 Truncate the output at a character boundary, since vsnprintf does not
21511 * charset.c (check_iso_charset_parameter): Convert internal
21512 character to string before calling 'error', since %c now has the
21514 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21515 overflow when computing char to be passed to 'error'. Do not
21516 pass Lisp_Object to 'error'; pass the integer instead.
21517 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21518 formatted with plain %d.
21520 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21522 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21524 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21526 * xterm.c (x_catch_errors): Remove duplicate declaration.
21528 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21530 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21532 2011-04-10 Jim Meyering <meyering@redhat.com>
21534 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21535 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21536 return ssize_t not "int", and use size_t as the buffer length.
21537 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21538 * gnutls.h: Update declarations.
21539 * process.c (read_process_output): Use ssize_t, to match.
21540 (send_process): Likewise.
21542 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21544 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21546 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21548 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21549 Use unsigned char, to match FcChar8 type definition.
21551 * xterm.c (handle_one_xevent):
21552 * xmenu.c (create_and_show_popup_menu):
21553 * xselect.c (x_decline_selection_request)
21554 (x_reply_selection_request): Avoid type-punned deref of X events.
21556 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21558 Fix some uses of `int' instead of EMACS_INT.
21559 * search.c (string_match_1, fast_string_match)
21560 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21561 (scan_buffer, find_next_newline_no_quit)
21562 (find_before_next_newline, search_command, Freplace_match)
21563 (Fmatch_data): Make some `int' variables be EMACS_INT.
21565 * xdisp.c (display_count_lines): 3rd argument and return value now
21566 EMACS_INT. All callers changed.
21567 (pint2hrstr): Last argument is now EMACS_INT.
21569 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21570 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21571 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
21572 (decode_coding_utf_16, decode_coding_emacs_mule)
21573 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
21574 (decode_coding_ccl, decode_coding_charset)
21575 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
21576 (decode_coding_iso_2022, decode_coding_emacs_mule)
21577 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
21578 <char_offset, last_offset>: Declare EMACS_INT.
21579 (encode_coding_utf_8, encode_coding_utf_16)
21580 (encode_coding_emacs_mule, encode_invocation_designation)
21581 (encode_designation_at_bol, encode_coding_iso_2022)
21582 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21583 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21585 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21586 (encode_invocation_designation): Last argument P_NCHARS is now
21588 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21589 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21591 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21594 * ccl.c (Fccl_execute_on_string): Declare some variables
21597 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21599 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21601 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21603 * process.c (Fformat_network_address): Doc fix.
21605 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21607 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21609 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21611 * keyboard.c (read_char): Call Lisp function help-form-show,
21612 instead of using internal_with_output_to_temp_buffer.
21613 (Qhelp_form_show): New var.
21614 (syms_of_keyboard): Use DEFSYM macro.
21616 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21618 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21620 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21622 * process.c (Flist_processes): Remove to Lisp.
21623 (list_processes_1): Delete.
21625 2011-04-06 Eli Zaretskii <eliz@gnu.org>
21627 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21629 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21631 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21633 Fix more problems found by GCC 4.6.0's static checks.
21635 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
21637 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21639 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21641 * xdisp.c (vmessage): Mark as a printf-like function.
21643 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21645 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21647 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21648 printf-like functions.
21649 (tiff_load): Add casts to remove these marks before passing them
21650 to system-supplied API.
21652 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21654 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21655 This avoids several warnings with gcc -Wstrict-overflow.
21656 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21657 directly, rather than having caller test rule sign. This avoids
21658 some unnecessary tests.
21659 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21660 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21661 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21663 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21664 (xfont_open): Avoid unnecessary tests.
21666 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21668 * composite.h, composite.c (composition_gstring_put_cache):
21669 Use EMACS_INT, not int, for length.
21671 * composite.h (COMPOSITION_DECODE_REFS): New macro,
21672 breaking out part of COMPOSITION_DECODE_RULE.
21673 (COMPOSITION_DECODE_RULE): Use it.
21674 * composite.c (get_composition_id): Remove unused local vars,
21675 by using the new macro.
21677 * textprop.c (set_text_properties_1): Change while to do-while,
21678 since the condition is always true at first.
21680 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21681 (interval_deletion_adjustment): Return unsigned value.
21684 * process.c (list_processes_1, create_pty, read_process_output):
21685 (exec_sentinel): Remove vars that were set but not used.
21686 (create_pty): Remove unnecessary "volatile"s.
21687 (Fnetwork_interface_info): Avoid possibility of int overflow.

21689 (read_process_output): Simplify nbytes computation if buffered.
21691 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
21693 * syntax.c (scan_words): Remove var that was set but not used.
21694 (update_syntax_table): Use unsigned instead of int.
21696 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21697 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21698 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21700 * print.c (print_error_message): Avoid int overflow.
21702 * font.c (font_list_entities): Redo for clarity,
21703 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21705 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21706 (font_score): Avoid potential overflow in diff calculation.
21708 * fns.c (substring_both): Remove var that is set but not used.
21709 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21711 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21713 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21714 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21715 can always succeed if overflow has undefined behavior.
21717 * search.c (boyer_moore, wordify): Remove vars set but not used.
21718 (wordify): Omit three unnecessary tests.
21720 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21721 All callers changed. This avoids the need for an unused var.
21723 * casefiddle.c (casify_region): Remove var that is set but not used.
21725 * dired.c (file_name_completion): Remove var that is set but not used.
21727 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21729 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21730 (Finsert_file_contents): Remove unnecessary code checking fd.
21732 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21733 Check for integer overflow on size calculations.
21735 * buffer.c (Fprevious_overlay_change): Remove var that is set
21738 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21739 Remove vars that are set but not used.
21740 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21741 (timer_check_2): Mark vars as initialized.

21746 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21748 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21749 that are set but not used.
21751 * xfns.c (make_invisible_cursor): Don't return garbage
21752 if XCreateBitmapFromData fails (Bug#8410).
21754 * xselect.c (x_get_local_selection, x_handle_property_notify):
21755 Remove vars that are set but not used.
21757 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

21762 (scroll_bar_windows_size): Now size_t, not int.
21763 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21764 Check for overflow.
21766 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21767 (map_tty_color) [!defined MSDOS]: Likewise.
21769 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21771 * coding.c: Remove vars that are set but not used.
21772 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

21781 * print.c (print_object): Remove var that is set but not used.
21783 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21784 The gnulib version avoids calling malloc in the usual case,
21785 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21786 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21787 * filelock.c (current_lock_owner): Likewise.
21788 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21789 * sysdep.c: Include allocator.h, careadlinkat.h.
21790 (emacs_no_realloc_allocator): New static constant.
21791 (emacs_readlink): New function.
21792 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

21819 do not dereference NULL upon failed strdup
21820 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21821 (ns_get_family): Likewise.
21823 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21825 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21827 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21829 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21832 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21834 Add lexical binding.
21836 * window.c (Ftemp_output_buffer_show): New fun.

21845 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21847 (syms_of_lread): Declare `lexical-binding'.
21849 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21851 * keyboard.c (eval_dyn): New fun.
21852 (menu_item_eval_property): Use it.
21854 * image.c (parse_image_spec): Use Ffunctionp.
21856 * fns.c (concat, mapcar1): Accept byte-code-functions.
21858 * eval.c (Fsetq): Handle lexical vars.
21859 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21860 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21861 (FletX, Flet): Obey lexical binding.
21862 (Fcommandp): Handle closures.
21863 (Feval): New `lexical' arg.
21864 (eval_sub): New function extracted from Feval. Use it almost
21865 everywhere where Feval was used. Look up vars in lexical env.
21867 (Ffunctionp): Move from subr.el.
21868 (Ffuncall): Handle closures.
21869 (apply_lambda): Remove `eval_flags'.
21870 (funcall_lambda): Handle closures and new byte-code-functions.
21871 (Fspecial_variable_p): New function.
21872 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21873 but without exporting it to Lisp.
21875 * doc.c (Fdocumentation, store_function_docstring):
21876 * data.c (Finteractive_form): Handle closures.
21878 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21881 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21883 (exec_byte_code): New function extracted from Fbyte_code to handle new
21884 calling convention for byte-code-functions. Add new byte-codes.
21886 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

21892 * xdisp.c (redisplay_internal): Fix prototype.
21894 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21896 * xdisp.c (SCROLL_LIMIT): New macro.
21897 (try_scrolling): Use it when setting scroll_limit.
21898 Limit scrolling to 100 screen lines.
21899 (redisplay_window): Even when falling back on "recentering",
21900 position point in the window according to scroll-conservatively,
21901 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21903 (try_scrolling): When point is above the window, allow searching
21904 as far as scroll_max, or one screenful, to compute vertical
21905 distance from PT to the scroll margin position. This prevents
21906 try_scrolling from unnecessarily failing when
21907 scroll-conservatively is set to a value slightly larger than the
21908 window height. Clean up the case of PT below the margin at bottom
21909 of window: scroll_max can no longer be INT_MAX. When aggressive
21910 scrolling is in use, don't let point enter the opposite scroll
21911 margin as result of the scroll.
21912 (syms_of_xdisp) <scroll-conservatively>: Document the
21913 threshold of 100 lines for never-recentering scrolling.

21920 (message_log_check_duplicate): Remove parameters `prev_bol' and
21921 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21922 (redisplay_internal): Remove parameter `preserve_echo_area',
21923 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21925 * indent.c (Fvertical_motion):
21926 * window.c (window_scroll_pixel_based, Frecenter):
21927 Don't pass `need_y_p' to `move_it_by_lines'.
21929 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21931 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21932 steal a few bits to be more compact.
21933 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21934 Remove unneeded casts.
21936 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21938 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21940 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21941 binding" message (bug#7967).
21943 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21945 Fix more problems found by GCC 4.6.0's static checks.
21947 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21948 Remove unused local var.
21950 * editfns.c (Fmessage_box): Remove unused local var.
21952 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21953 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21954 Omit unused local vars.
21955 * window.c (shrink_windows): Omit unused local var.
21956 * menu.c (digest_single_submenu): Omit unused local var.
21957 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21958 Omit unused local var.
21960 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21961 Don't assume string length fits in int.
21962 (keyremap_step, read_key_sequence): Use size_t for sizes.

21966 instead of alloca (Bug#8344).
21968 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21969 (Fbacktrace_frame): Don't assume nframes fits in int.

21978 * cm.c (calccost): Turn while-do into do-while, for clarity.
21980 * keyboard.c (syms_of_keyboard): Use the same style as later
21981 in this function when indexing through an array. This also
21982 works around GCC bug 48267.
21984 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21986 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21988 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21989 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21991 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21992 This avoids undefined behavior on integer overflow, and is a bit
21993 more convenient anyway since it is compared to a size_t variable.
21995 Variadic C functions now count arguments with size_t, not int.
21996 This avoids an unnecessary limitation on 64-bit machines, which
21997 caused (substring ...) to crash on large vectors (Bug#8344).

22007 * fns.c (concat): Likewise.
22008 * frame.c (x_set_frame_parameters): Likewise.
22009 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22010 0 if not found, not -1. All callers changed.
22012 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22013 (stack_copy_size): Now size_t, not int.
22014 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

22038 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22039 Vcommand_hook_internal.

22172 (x_create_tip_frame): Remove unused variable `tem'.
22174 * w32inevt.c (w32_console_read_socket):
22175 Remove unused variable `no_events'.
22177 * w32term.c (x_draw_composite_glyph_string_foreground):
22178 Remove unused variable `width'.
22180 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
22182 * w32term.c (x_set_glyph_string_clipping):
22183 Don't pass uninitialized region to CombineRgn.
22185 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
22187 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
22188 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
22189 (Fx_close_connection): Remove unused variable `i'.

22207 2011-03-23 Julien Danjou <julien@danjou.info>
22209 * term.c (Fsuspend_tty, Fresume_tty):
22210 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22211 * window.c (temp_output_buffer_show):
22212 * insdel.c (signal_before_change):
22213 * frame.c (Fhandle_switch_frame):
22214 * fileio.c (Fdo_auto_save):

22217 * cmds.c (internal_self_insert):
22218 * callint.c (Fcall_interactively):
22219 * buffer.c (Fkill_all_local_variables):
22220 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22222 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22223 unconditionally since it does the check itself.
22225 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22227 Fix more problems found by GCC 4.5.2's static checks.
22229 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22230 the first time through the loop, since we know p0 < p1 then.
22231 This also avoids a gcc -Wstrict-overflow warning.
22233 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22234 leading to a memory leak, possible in functions like
22235 load_charset_map_from_file that can allocate an unbounded number
22236 of objects (Bug#8318).
22238 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22239 that could (at least in theory) be that large.
22241 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22242 This is less likely to overflow, and avoids undefined behavior if
22243 overflow does occur. All callers changed. Use strtoul to scan
22244 for the unsigned long integer.
22245 (pint2hrstr): Simplify and tune code slightly.
22246 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22248 * scroll.c (do_scrolling): Work around GCC bug 48228.
22249 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
22251 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
22252 This also avoids a warning with gcc -Wstrict-overflow.
22253 (validate_x_resource_name): Simplify count usage.
22254 This also avoids a warning with gcc -Wstrict-overflow.
22256 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22259 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22261 * process.c (Fmake_network_process): Use socklen_t, not int,
22262 where POSIX says socklen_t is required in portable programs.
22263 This fixes a porting bug on hosts like 64-bit HP-UX, where
22264 socklen_t is wider than int (Bug#8277).
22265 (Fmake_network_process, server_accept_connection):
22266 (wait_reading_process_output, read_process_output):
22269 * process.c: Rename or move locals to avoid shadowing.

22279 Make tparam.h and terminfo.c consistent.
22280 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22281 Include tparam.h instead, since it declares them.
22282 * cm.h (PC): Remove extern decl; tparam.h now does this.
22283 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22284 * terminfo.c: Include tparam.h, to check interfaces.
22285 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22286 (tparam): Adjust signature to match interface in tparam.h;
22287 this removes some undefined behavior. Check that outstring and len
22288 are zero, which they always are with Emacs.
22289 * tparam.h (PC, BC, UP): New extern decls.
22291 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22292 (xftfont_open): Rename locals to avoid shadowing.
22294 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
22295 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
22296 (OTF_TAG_SYM): Omit macro if not needed.
22297 (ftfont_list): Remove unused local.
22298 (get_adstyle_property, ftfont_pattern_entity):
22299 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
22300 Rename locals to avoid shadowing.

22304 * xml.c (make_dom): Now static.
22306 * composite.c (composition_compute_stop_pos): Rename local to
22308 (composition_reseat_it): Remove unused locals.
22309 (find_automatic_composition, composition_adjust_point): Likewise.
22310 (composition_update_it): Mark var as initialized.
22311 (find_automatic_composition): Mark vars as initialized,
22312 with a FIXME (Bug#8290).
22314 character.h: Rename locals to avoid shadowing.
22315 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22316 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22317 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22318 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22319 to avoid shadowing.
22321 * textprop.c (property_change_between_p): Remove; unused.
22323 * intervals.c (interval_start_pos): Now static.
22325 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

22328 Rename locals to avoid shadowing.
22330 * sound.c (wav_play, au_play, Fplay_sound_internal):
22331 Fix pointer signedness.
22332 (alsa_choose_format): Remove unused local var.
22333 (wav_play): Initialize a variable to 0, to prevent undefined
22334 behavior (Bug#8278).
22336 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22338 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22340 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22341 clobbering (Bug#8298).
22342 * sysdep.c (sys_subshell): Likewise.
22343 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22345 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22346 This should get cleaned up, so that child_setup has the
22347 same signature on all platforms.
22349 * callproc.c (call_process_cleanup): Now static.
22350 (relocate_fd): Rename locals to avoid shadowing.
22352 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22354 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22355 not to be necessary, and produces flickering.
22357 2011-03-20 Glenn Morris <rgm@gnu.org>
22359 * config.in: Remove file.
22361 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
22363 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
22364 are now in src/globals.h.
22365 (syms_of_minibuf): Remove spurious & from previous change.
22367 2011-03-20 Leo Liu <sdl.web@gmail.com>
22369 * minibuf.c (completing-read-function): New variable.
22370 (completing-read-default): Rename from completing-read.
22371 (completing-read): Call completing-read-function.
22373 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
22375 * xfaces.c (Fx_load_color_file):
22376 Read color file from absolute filename (bug#8250).
22378 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
22380 * makefile.w32-in: Update dependencies.
22382 2011-03-17 Eli Zaretskii <eliz@gnu.org>
22384 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

22391 (sigchld_handler): Now static.
22393 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
22394 That way, the code declares only the vars that it needs.
22395 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
22396 * s/cygwin.h (PTY_ITERATION): Likewise.
22397 * s/darwin.h (PTY_ITERATION): Likewise.

22403 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
22404 (CONSTANTLIM): Remove; unused.
22405 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
22406 Define only if needed.
22408 * unexelf.c (unexec): Name an expression,
22409 to avoid gcc -Wbad-function-cast warning.
22410 Use a different way to cause a compilation error if anyone uses
22411 n rather than nn, a way that does not involve shadowing.
22412 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22414 * deps.mk (unexalpha.o): Remove; unused.
22416 New file unexec.h, the (simple) interface for unexec (Bug#8267).
22417 * unexec.h: New file.
22418 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
22419 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
22420 Depend on unexec.h.
22421 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
22422 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
22423 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
22424 Change as necessary to match prototype in unexec.h.
22426 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
22428 (back_comment, skip_chars): Mark vars as initialized.

22442 instead of using an uninitialized var.
22443 (font_sort_entities): Mark var as initialized.
22445 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
22447 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

22471 * callint.c (quotify_arg, quotify_args): Now static.
22472 (Fcall_interactively): Rename locals to avoid shadowing.
22473 Use const pointer when appropriate.
22475 * lisp.h (get_system_name, get_operating_system_release):

22479 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
22480 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22481 some of which prompt warnings from gcc -Wbad-function-cast.
22482 (Fformat_time_string, Fencode_time, Finsert_char):
22483 (Ftranslate_region_internal, Fformat):
22484 Rename or remove local vars to avoid shadowing.
22485 (Ftranslate_region_internal): Mark var as initialized.
22487 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
22490 * lisp.h (eassert): Check that the argument compiles, even if
22491 ENABLE_CHECKING is not defined.
22493 * data.c (Findirect_variable): Name an expression, to avoid
22494 gcc -Wbad-function-cast warning.

22502 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
22503 Rename locals to avoid shadowing.
22504 (mark_stack): Move local variables into the #ifdef region where
22506 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
22507 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
22509 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
22510 (GC_STRING_CHARS): Remove; not used.
22511 (Fmemory_limit): Cast sbrk's returned value to char *.
22513 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
22514 avoids undefined behavior in theory.
22516 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.

22519 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22520 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22521 to use the following functions instead of these macros.
22522 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22523 EMACS_INT, since callers assume the returned value fits in int.
22524 (upcase1): Likewise, for UPCASE_TABLE.
22525 (uppercasep, lowercasep, upcase): New static inline functions.
22526 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
22527 the race-condition problem in the old DOWNCASE.

22530 Rename locals to avoid shadowing.
22531 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
22532 (regex_compile, re_search_2, re_match_2_internal):
22533 Remove unused local vars.
22534 (FREE_VAR): Rewrite so as not to use empty "else",
22535 which gcc can warn about.
22536 (regex_compile, re_match_2_internal): Mark locals as initialized.
22537 (RETALLOC_IF): Define only if needed.
22538 (WORDCHAR_P): Likewise. This one is never needed, but is used
22539 only in a comment talking about a compiler bug, so put inside
22540 the #if 0 of that comment.
22541 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22542 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
22545 * search.c (boyer_moore): Rename locals to avoid shadowing.
22546 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
22547 (PREV_CHAR_BOUNDARY): Likewise.
22549 * search.c (simple_search): Remove unused var.
22551 * dired.c (compile_pattern): Move decl from here ...

22559 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
22560 Rename locals to avoid shadowing.
22561 (Fvertical_motion): Mark locals as initialized.
22563 * casefiddle.c (casify_object, casify_region): Now static.
22564 (casify_region): Mark local as initialized.
22566 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
22568 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22569 New macros, so that the caller can use some names other than
22570 gcpro1, gcpro2, etc.
22571 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22573 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22574 argument, for consistency with GCPRO2_VAR, etc: it is now the
22575 prefix of the variable, not the variable itself. All uses
22577 * dired.c (directory_files_internal, file_name_completion):
22578 Rename locals to avoid shadowing.
22580 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22581 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22582 dired.c's scmp function, had undefined behavior.
22583 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22584 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22585 * buffer.h: ... to here, because these macros use current_buffer,
22586 and the new implementation with inline functions needs to have
22587 current_buffer in scope now, rather than later when the macros
22589 (downcase, upcase1): New static inline functions.
22590 (DOWNCASE, UPCASE1): Reimplement using these functions.
22591 This avoids undefined behavior in expressions like
22592 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22593 from race conditions in accessing the global variables
22594 case_temp1 and case_temp2.
22595 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22596 * lisp.h (case_temp1, case_temp2): Remove their decls.
22597 * character.h (ASCII_CHAR_P): Move from here ...
22598 * lisp.h: ... to here, so that the inline functions mentioned
22599 above can use them.
22601 * dired.c (directory_files_internal_unwind): Now static.
22603 * fileio.c (file_name_as_directory, directory_file_name):
22604 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
22606 (file_name_as_directory): Use const pointers when appropriate.
22607 (Fexpand_file_name): Likewise. In particular, newdir might
22608 point at constant storage, so make it a const pointer.
22609 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22610 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22612 (Fset_file_times, Finsert_file_contents, auto_save_error):
22613 Rename locals to avoid shadowing.
22615 * minibuf.c (choose_minibuf_frame_1): Now static.
22616 (Ftry_completion, Fall_completions): Rename or remove locals
22617 to avoid shadowing.
22619 * marker.c (bytepos_to_charpos): Remove; unused.
22621 * lisp.h (verify_bytepos, count_markers): New decls,
22622 so that gcc does not warn that these functions aren't declared.

23045 All callers of tparam changed to use tparam's actual API.
23046 * tparam.c (tparam1, tparam, tgoto):
23047 Use const pointers where appropriate.
23049 * cm.c (calccost, cmgoto): Use const pointers where appropriate.
23050 * cm.h (struct cm): Likewise.
23051 * dispextern.h (do_line_insertion_deletion_costs): Likewise.

23055 (turn_on_face, init_tty): Likewise.
23056 * termchar.h (struct tty_display_info): Likewise.
23058 * term.c (term_mouse_position): Rename local to avoid shadowing.
23060 * alloc.c (mark_ttys): Move decl from here ...
23061 * lisp.h (mark_ttys): ... to here, so that it's checked against defn.
