180 'fullscreen' parameter. Always record previous width and height
181 of the frame, except when switching out of maximized modes, so
182 that they could be restored correctly, instead of resetting to the
183 default frame dimensions. Send SC_RESTORE command to the frame,
184 unless we are going to send SC_MAXIMIZE, to restore the frame

333 * coding.c (detect_ascii): New function.
334 (detect_coding): Set coding->head_ascii and coding->eol_seen only

337 source bytes directly.
338 (produce_chars): Call insert_from_gap with the new arg 0.
339 (encode_coding): Likewise.
340 (decode_coding_gap): Control ASCII optimization by the variable

373 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
374 too so that these builds can use Cygwin's file conversion
375 functions. (We've been building and linking cygw32.o all along
376 and just not using it.)
378 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>

392 activated, call w32fullscreen_hook, to make sure the new frame
393 dimensions are in effect. (Bug#13937)
395 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
397 * xdisp.c (init_iterator): Simplify because both character and byte
398 positions are either specified or -1. Add eassert. Adjust comment.

420 Include <sys/param.h> unconditionally, as that works elsewhere and
421 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
422 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin

429 2013-03-11 Stefan Monnier <monnier@iro.umontreal.ca>

506 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
508 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
509 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
510 from Elisp via unread-command-events.

513 functions to mean "no change".
515 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
517 region-cache.c, scroll.c, search.c: Use bool for booleans.
518 * lisp.h (compile_pattern):
519 * scroll.c (do_scrolling, do_direct_scrolling):
520 * search.c (struct regexp_cache, compile_pattern_1)
521 (compile_pattern, string_match_1, search_command)

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

537 Adjust call to find_newline.
538 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

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

648 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
649 * sysdep.c (list_system_processes)
650 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
651 Make it a stub in this case; otherwise the build might fail,
652 and this code hasn't been tested on such hosts anyway.
653 Problem reported by Nelson H. F. Beebe in
654 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
655 and analyzed by Jérémie Courrèges-Anglas in
656 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
658 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
660 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.

666 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
668 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
669 * filelock.c: Include <c-ctype.h>.
670 (MAX_LFINFO): New top-level constant.
671 (lock_info_type): Remove members pid, boot_time. Add members at,
672 dot, colon. Change user member to be the entire buffer, not a
673 pointer. This allows us to handle the case where a foreign
674 pid or boot time exceeds the local range. All uses changed.
675 (LINKS_MIGHT_NOT_WORK): New constant.
676 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
677 (defined_WINDOWSNT): Remove.
678 (MAKE_LOCK_NAME, file_in_lock_file_name):
679 Always use .#FILE (not .#-FILE) for the file lock,
680 even if it is a regular file.
681 (rename_lock_file): New function.
682 (create_lock_file): Use it.
683 (create_lock_file, read_lock_data):
684 Prefer a symbolic link for the lock file, falling back on a
685 regular file if symlinks don't work. Do not try to create
686 symlinks on MS-Windows, due to security hassles. Stick with
687 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
688 link, rename, unlink, mkstemp) when creating locks, as a GNUish
689 host may be using a Windowsish file system, and cannot use
690 MS-Windows-only system calls. Fall back on mktemp if mkstemp
691 doesn't work. Don't fail merely because of a symlink-contents
692 length limit in the current file system; fall back on regular
693 files. Increase the symlink contents length limit to 8 KiB, this
694 should be big enough for any real use and doesn't crunch the
696 (create_lock_file, lock_file_1, read_lock_data):
697 Simplify allocation of lock file buffers now that they fit in 8 KiB.
698 (lock_file_1): Return error number, not bool. All callers changed.
699 (ELOOP): New macro, if not already defined.
700 (read_lock_data): Return size of lock file contents, not Lisp object.
701 All callers changed. Handle a race condition if some other process
702 replaces a regular-file lock with a symlink lock or vice versa,
703 while we're trying to read the lock.
704 (current_lock_owner): Parse contents more carefully, to help avoid
705 confusing a regular-file lock with some other application's use
706 of the file. Check for lock file contents being too long, or
707 not parsing correctly.
708 (current_lock_owner, lock_file):
709 Allow foreign pid and boot times that exceed the local range.
710 (current_lock_owner, lock_if_free, lock_file):
711 Simplify allocation of lock file contents.
712 * w32.c (sys_rename_replace): New function, containing most of
713 the contents of the old sys_rename.
714 (sys_rename): Use it.
715 (fchmod): New dummy function.
716 * w32.h (sys_rename_replace, fchmod): New decls.
718 2013-03-05 Eli Zaretskii <eliz@gnu.org>
720 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
721 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
722 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
723 <dmantipov@yandex.ru>.
725 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
727 * composite.c (get_composition_id, fill_gstring_header):
728 Use make_uninit_vector where appropriate.
729 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
730 * xselect.c (clean_local_selection_data): Likewise.
732 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
734 Fix misuse of ImageMagick that caused core dump (Bug#13846).
735 * image.c (imagemagick_load_image): Calculate height and width
736 after flattening the image, not before.
738 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
740 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
741 * ftfont.c (ftfont_shape_by_flt): Likewise.
742 * w32uniscribe.c (uniscribe_shape): Likewise.
744 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
746 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
747 The old approach, which fell back on DIR/.#FILE.0 through
748 DIR/.#FILE.9, had race conditions that could not be easily fixed.
749 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
750 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
751 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
752 because the locking mechanism was never reliable in that case).
753 This patch fixes this and other bugs discovered by a code
754 inspection that was prompted by
755 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
756 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
757 to avoid interoperability problems between the MS-Windows and
758 non-MS-Windows implementations. MS-Windows and non-MS-Windows
759 instances of Emacs now ignore each others' locks.
760 * filelock.c (defined_WINDOWSNT): New constant.
761 (MAKE_LOCK_NAME, fill_in_lock_file_name):
762 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
763 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
764 regular files on MS-Windows hosts.
765 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
766 Use SAFE_ALLOCA to avoid problems with long file names.
767 (MAX_LFINFO): Now a local constant, not a global macro.
768 (IS_LOCK_FILE): Remove.
769 (lock_file_1): Don't inspect errno if symlink call succeeds;
771 (lock_file): Document that this function can return if lock
773 (lock_file): Don't access freed storage.
775 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

779 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
781 * textprop.c: Use bool for booleans.
782 (validate_interval_range, Fadd_text_properties)
783 (Fremove_text_properties): Prefer bool to int when either works.
785 2013-03-02 Eli Zaretskii <eliz@gnu.org>
787 * textprop.c (Fadd_text_properties, Fremove_text_properties):
788 If the interval tree changes as a side effect of calling
789 modify_region, re-do processing starting from the call to
790 validate_interval_range. (Bug#13743)
792 2013-02-28 Eli Zaretskii <eliz@gnu.org>
794 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
797 2013-02-27 Eli Zaretskii <eliz@gnu.org>
799 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
800 _SH_DENYRW flag, instead of emacs_open, to deny any other process
801 access to the lock file until it is written and closed.
804 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
806 * callint.c (Qcall_interactively):
807 * macros.c (Qexecute_kbd_macro):

812 * window.c (Frecenter): Tiny docstring enhancement.
814 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
816 Minor textprop integer cleanup.
817 * intervals.h, textprop.c (add_text_properties_from_list):
818 Return void, not int, since nobody uses the return value.
819 * textprop.c (validate_plist, add_properties, remove_properties)
820 (Fadd_text_properties):
821 Don't assume list length fits in int.
822 (interval_has_all_properties, interval_has_some_properties)
823 (interval_has_some_properties_list, add_properties, remove_properties)
824 (Fadd_text_properties, Fremove_text_properties)
825 (Fremove_list_of_text_properties, text_property_stickiness):
826 Use bool for booleans.
827 (Fadd_text_properties, Fremove_text_properties):
828 (Fremove_list_of_text_properties):
829 Reindent do-while as per GNU style.

833 Implement CLASH_DETECTION for MS-Windows.
835 * filelock.c [WINDOWSNT]: Include w32.h.
836 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
837 function of that name. Up-case the macro arguments.
838 (IS_LOCK_FILE): New macro.
839 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
840 (create_lock_file): New function, with body extracted from
842 [WINDOWSNT]: Implement lock files by writing a regular file with
843 the lock information as its contents.
844 (read_lock_data): New function, on Posix platforms just calls
846 [WINDOWSNT]: Read the lock info from the file.
847 (current_lock_owner): Call read_lock_data instead of calling
848 emacs_readlinkat directly.
849 (lock_file) [WINDOWSNT]: Run the file name through
852 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
853 just check if the process by that PID exists.
855 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
856 also present, as doing so will fail to error out if the file
859 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
861 * textprop.c (Fadd_text_properties, Fremove_text_properties)
862 (Fremove_list_of_text_properties): Skip all of the intervals in
863 the region between START and END that already have resp. don't
864 have the requested properties, not just the first one.
865 Add assertions that the loop afterwards always modifies the
866 properties. (Bug#13743)

931 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
932 This avoids warning messages reported as part of Bug#13546.

968 2013-02-19 Eli Zaretskii <eliz@gnu.org>
970 * w32proc.c (new_child): Avoid leaking handles if the subprocess
971 resources were not orderly released.
973 2013-02-17 Eli Zaretskii <eliz@gnu.org>
975 * xdisp.c (x_draw_vertical_border): For a window that is neither

999 * w32.c (sys_chown): Remove unused function.
1001 * w32term.c <input_signal_count>: Declare 'volatile'
1002 unconditionally. (Bug#9066)
1004 * w32.c (set_errno): Reset h_errno and don't set it to any other
1005 value. Set errno instead.

1014 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1016 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
1018 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1020 * keyboard.c (read_char): Fix calculation of auto-save time out
1021 when auto-save-timeout is less than 4. (Bug#13720)
1023 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

1031 (socket_to_fd): Add assertion against indexing fd_info[] with a
1032 value that is out of bounds.
1033 (sys_accept): If fd is negative, do not set up the child_process
1034 structure for reading.
1036 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
1038 * composite.c (fill_gstring_header): Remove useless prototype.

1050 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1052 Fix AIX port (Bug#13650).
1053 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1054 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1055 was #undeffed earlier, so it cannot be used as a macro here.
1056 Use the constant and not the macro.
1058 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1060 * w32proc.c (new_child): If no vacant slots are found in
1061 child_procs[], make another pass looking for slots whose process

1094 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1096 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1098 Improve AIX port some more (Bug#13650).
1099 With this, it should be as good as it was in 23.3, though it's
1100 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1101 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1102 * unexaix.c (start_of_text): Remove.
1103 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1104 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1105 (orig_load_scnptr, orig_data_scnptr):
1106 Now off_t, not long, since they are file offsets.
1107 (make_hdr): Use _data, not start_of_data ().
1108 This is the key part of the fix.
1109 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1110 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1112 * pre-crt0.c (data_start): Initialize to 1.
1113 This ports to compilers that optimize the external declaration
1114 'int x = 0;' as if it were 'int x;' to shrink the executable.
1116 Improve AIX port (Bug#13650).
1117 This doesn't fix the bug, but it makes progress: Emacs builds now.
1118 * unexaix.c: Include inttypes.h, stdarg.h.
1119 (report_error, report_error_1): Mark as _Noreturn.
1120 (report_error): Don't report the wrong errno.
1121 (report_error_1): Now varargs. All callers changed.
1122 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1123 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1124 (write_ptr): Use %p to print address rather than %lx and a cast
1125 to unsigned long. Grow buffer a bit, to be safer.
1127 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1129 * bidi.c (bidi_resolve_neutral): After finding the next
1130 non-neutral character, accept NEUTRAL_ON type as well, because
1131 directional control characters, such as LRE and RLE, have their
1132 type converted to that by bidi_resolve_weak. This avoids aborts
1133 when LRE/RLE follows a run of neutrals.
1134 (bidi_move_to_visually_next): Assert that return value of
1135 bidi_peek_at_next_level is non-negative. Negative values will
1138 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1140 Minor getenv-related fixes.
1141 * callproc.c (Fcall_process_region) [!DOS_NT]:

1143 * callproc.c (init_callproc):
1144 * dispnew.c (init_display):
1145 * sysdep.c (sys_subshell):
1146 Omit unnecessary cast of getenv or egetenv.

1150 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1151 Update dependencies.
1153 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1155 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1157 (display_line): Set w->region_showing to the value of
1158 it->region_beg_charpos, not to -1. This fixes redisplay
1159 optimization when cursor is moved up after M->. (Bug#13623)
1161 (try_scrolling): Scroll text up more if point is too close to ZV
1162 and inside the scroll margin. This makes sure point is moved
1163 outside the scroll margin in these cases.
1165 * window.h (struct window): region_showing can no longer be
1168 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1170 Tune by using memchr and memrchr.
1171 * doc.c (Fsnarf_documentation):
1172 * fileio.c (Fsubstitute_in_file_name):
1173 * search.c (find_newline, scan_newline):
1174 * xdisp.c (pos_visible_p, display_count_lines):
1175 Use memchr and memrchr rather than scanning byte-by-byte.
1176 * search.c (find_newline): Rename from scan_buffer.
1177 Omit first arg TARGET, as it's always '\n'. All callers changed.
1179 Clean up read_key_sequence a tiny bit more.
1180 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1181 (read_key_sequence): Remove unused locals.
1183 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1185 Clean up read_key_sequence a bit; reread active keymaps after first event.
1186 * keyboard.c (read_char, read_char_x_menu_prompt)
1187 (read_char_minibuf_menu_prompt):
1188 Replace nmaps+maps with a single `map' arg.
1189 (follow_key): Operate on a single map.
1190 (active_maps): New function.
1191 (test_undefined): Also return true for nil bindings.
1192 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1193 a single (composed) keymap. Remember `first_event' to choose the right
1194 set of active keymaps. Recompute the set of keymaps after receiving
1195 the first event. Remove GOBBLE_FIRST_EVENT.
1196 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1197 * keyboard.h (read_char): Update declaration.
1198 * lread.c (read_filtered_event): Adjust call to read_char.
1200 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1202 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1203 Don't use the limitation on backwards movement when lines are truncated
1204 in the window. (Bug#13675)
1206 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1208 * marker.c (set_marker_internal): If desired position is passed
1209 as a marker, avoid call to buf_charpos_to_bytepos.
1210 * window.c (Fset_window_point): Omit redundant type checking.
1211 (Fset_window_start): Likewise. Format comment.
1212 (window_scroll_pixel_based): Use set_marker_restricted_both
1213 with character and byte positions obtained from an iterator.
1214 (Fset_window_configuration): Use set_marker_restricted_both.
1215 * xdisp.c (message_dolog): Likewise.
1217 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1219 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1220 When text lines are longer than window's screen lines, don't move back
1221 too far. This speeds up some redisplay operations. (Bug#13675)
1223 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1225 * syntax.c (scan_sexps_forward): Fix byte position calculation
1226 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1228 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
1230 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
1231 that was not needed.
1233 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1235 Minor hashing refactoring.
1236 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1237 (sxhash_float): Return EMACS_UINT, for consistency with the other
1239 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1240 non-static inline function and therefore can't use static vars.
1241 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1242 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1243 with the other hash functions.
1245 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1247 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1248 XXXXXX part of the temporary file pattern is not downcased even
1249 when w32-downcase-file-names is non-nil. (Bug#13661)
1251 * xdisp.c (decode_mode_spec): Remove handling of %t.
1253 * msdos.c (careadlinkatcwd): Remove.
1255 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1257 * lread.c (skip_dyn_bytes): New function (bug#12598).
1258 (read1): Use it. Use getc instead of READCHAR to read bytes.
1259 (load_each_byte): Remove. Update users.
1261 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1263 * search.c (scan_buffer): Calculate end byte position just once.

1267 (scan_sexps_forward): Record from_byte and avoid redundant
1268 character to byte position calculation ...
1269 (Fparse_partial_sexp): ... here. Break too long line.
1271 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1273 * lisp.h (make_uninit_vector): New function.
1274 * alloc.c (Fvector, Fmake_byte_code):

1286 * window.c (Fcurrent_window_configuration):
1287 * xfaces.c (Fx_family_fonts):
1288 * xselect.c (selection_data_to_lisp_data): Use it.
1290 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
1292 * coding.c (Fdefine_coding_system_internal): Use AREF where
1293 argument is known to be a vector.
1294 * fns.c (Flocale_info): Likewise for ASET.
1295 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1296 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1298 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1300 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1303 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
1304 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
1305 updateCollectionBehaviour.

1308 (ns_last_use_native_fullscreen): New variable.
1309 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.

1311 if isFullscreen returns YES.
1312 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1313 (check_native_fs): New function.
1314 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
1315 (ns_term_init): Remove NEW_STYLE_FS.
1316 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
1317 and tool bar if isFullscreen returns NO.
1318 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
1319 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
1320 with HAVE_NATIVE_FS.
1321 (window:willUseFullScreenPresentationOptions:): New method.
1322 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
1323 Hide toolbar if not enabled (Bug#13444).
1324 (windowDidExitFullScreen:): Call updateCollectionBehaviour.

1326 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
1327 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
1328 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
1329 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
1330 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1331 (syms_of_nsterm): Add ns-use-native-fullscreen.
1333 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1335 * fileio.c (Qchoose_write_coding_system): Now static.
1337 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1339 * xdisp.c (window_buffer_changed): region_showing can be negative,
1340 which still means region is being displayed.
1341 (redisplay_internal): Resurrect code that forced redisplay of the
1342 whole window when showing region and the mark has changed.
1343 Record the new mark position to allow redisplay optimizations.
1344 (display_line): If it->region_beg_charpos is non-zero, set the
1345 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1347 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1348 not bitfield of 1 bit.
1350 2013-02-03 Daniel Colascione <dancol@dancol.org>
1352 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1353 daemon mode works on cygw32 when Emacs is installed and not just
1356 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1358 Avoid file time stamp bug on MS-Windows (Bug#13149).
1359 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1360 as FAT32 doesn't update time stamps when truncating them.
1361 Also, check that a file time stamp is not a multiple of 100 ns;
1362 this should catch all instances of the problem on MS-Windows,
1363 as its native file system resolution is 100 ns or worse, and
1364 checking for a non-multiple of 100 ns should impose only a small
1365 overhead on systems with ns resolution.
1367 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1369 Avoid encoding file names on MS-Windows when they need to be run
1370 through dostounix_filename.
1371 * w32.c (normalize_filename): Accept an additional argument
1372 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1373 downcase it even if w32-downcase-file-names is non-nil.
1374 (dostounix_filename): Accept an additional argument MULTIBYTE and
1375 pass it to normalize_filename.
1376 (emacs_root_dir): Adjust.
1378 * msdos.h (dostounix_filename): Adjust prototype.
1380 * w32.h (dostounix_filename): Adjust prototype.
1382 * msdos.c (dostounix_filename): Accept an additional argument and
1384 (init_environment): Adjust callers of dostounix_filename.
1386 * fileio.c (Ffile_name_directory, file_name_as_directory)
1387 (directory_file_name, Fexpand_file_name)
1388 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1390 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1392 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1393 variables, as egetenv is case-insensitive for DOS_NT.
1395 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1396 with an encoded file name.
1398 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1399 Adjust calls to dostounix_filename.
1401 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1403 * unexw32.c (unexec): Adjust call to dostounix_filename.
1405 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1407 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1410 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1413 * callproc.c (Fcall_process): Make sure program name in PATH and
1414 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1415 is passed to exec/spawnve, which fails unless the file-name
1418 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1419 even if w32-quote-process-args is nil.
1421 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1423 Fix timestamp bug when write-region appends nothing (Bug#13149).
1424 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1425 the file's time stamp doesn't change if Emacs happens to write nothing
1426 to the file, and on a buggy file system this could cause Emacs to
1427 incorrectly infer that the file system doesn't have the bug.
1428 Avoid this problem by inhibiting the inference in this case.
1430 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1432 * window.h (struct window): Convert base_line_number, base_line_pos
1433 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1434 Convert region_showing member from Lisp_Object to bitfield.
1435 Remove sequence_number member. Adjust comments.
1436 * window.c (sequence_number): Remove.
1437 (make_window): Initialize column_number_displayed.
1438 * print.c (print_object): Follow the printed representation of
1439 frames and print window pointer to distinguish between windows.
1440 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1441 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1442 (wset_column_number_displayed, wset_region_showing): Remove.
1443 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1444 (try_scrolling, try_cursor_movement, redisplay_window)
1445 (try_window_reusing_current_matrix, try_window_id, display_line)
1446 (display_mode_lines, decode_mode_spec): Adjust users.
1447 * .gdbinit (pwinx): Do not print sequence_number.
1449 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1451 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1452 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1453 * dired.c: Include <fcntl.h>.
1454 (open_directory): New function, which uses open and fdopendir
1455 rather than opendir. DOS_NT platforms still use opendir, though.
1456 (directory_files_internal, file_name_completion): Use it.
1457 (file_attributes): New function, with most of the old Ffile_attributes.
1458 (directory_files_internal, Ffile_attributes): Use it.
1459 (file_attributes, file_name_completion_stat): First arg is now fd,
1460 not dir name. All uses changed. Use fstatat rather than lstat +
1462 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1463 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1464 (emacs_readlinkat): New function, with much of the old
1465 Ffile_symlink_p, but with an fd argument for speed.
1466 It uses readlinkat rather than careadlinkatcwd, so that it
1467 need not assume the working directory.
1468 (Ffile_symlink_p): Use it.
1469 * filelock.c (current_lock_owner): Use emacs_readlinkat
1470 rather than emacs_readlink.
1471 * lisp.h (emacs_readlinkat): New decl.
1472 (READLINK_BUFSIZE, emacs_readlink): Remove.
1473 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1474 (emacs_norealloc_allocator, emacs_readlink): Remove.
1475 This stuff is moved to fileio.c.
1476 * w32.c (fstatat, readlinkat): New functions.
1477 (careadlinkat): Don't check that fd == AT_FDCWD.
1478 (careadlinkatcwd): Remove; no longer needed.

1484 Move the last piece of choose_write_coding_system here. (Bug#13522)
1485 (syms_of_fileio): Add choose-write-coding-system.
1487 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1489 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1490 (sys_close): Zero out the flags for the file descriptor before
1491 closing it. (Bug#13546)
1493 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1494 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1495 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1498 * w32.c (w32_get_long_filename, init_environment, readlink):
1499 Support file names encoded in DBCS codepages.
1500 (readlink): Use the current file-name-coding-system, not the ANSI
1501 codepage, to decode and handle targets of symlinks.
1503 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1505 * w32.c (opendir): Now accepts a 'const char *'.
1507 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1509 Remove obsolete redisplay code. See the discussion at
1510 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1511 * dispnew.c (preemption_period, preemption_next_check): Remove.
1512 (Vredisplay_preemption_period): Likewise.
1513 (update_frame, update_single_window, update_window, update_frame_1):
1514 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1515 used, following the 2012-06-22 change.
1517 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1519 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1521 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1523 * font.c (num_fonts): Remove the leftover from old
1524 debugging code. Adjust comment style here and there.
1525 * insdel.c (insert_1): Remove.
1526 * lisp.h (insert_1): Remove prototype.
1527 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1529 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1531 * w32.c (max_filename_mbslen): New function.
1532 (normalize_filename, readdir): Use it to detect locales where ANSI
1533 encoding of file names uses a double-byte character set (DBCS).
1534 If a DBCS encoding is used, advance by characters using
1535 CharNextExA, instead of incrementing a 'char *' pointer.
1536 Use _mbslwr instead of _strlwr. (Bug#13515)
1538 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1539 request of memory reservation to 1.7GB. (Bug#13065)
1541 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1543 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1544 at check_extra_latin label. (Bug#13505)
1546 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1548 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1549 Avoid redundant calls to strlen.
1551 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1553 Drop async_visible and async_iconified fields of struct frame.
1554 This is possible because async input is gone; for details, see
1555 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1556 * frame.h (struct frame): Remove async_visible and async_iconified
1557 members, convert garbaged to unsigned bitfield. Adjust comments.
1558 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1559 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1560 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1561 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1562 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1564 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1565 properly. Likewise for obscured.
1567 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1570 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1572 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1574 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1575 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1577 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1579 * xdisp.c (message2, message2_nolog): Remove functions.
1580 (message3, message3_nolog): Extract nbytes and multibyteness directly
1581 from the string. Change all callers.
1582 (message3_nolog): Don't set message_enable_multibyte since set_message
1583 will reset it anyway.
1584 (message1, message1_nolog): Use message3.
1585 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1586 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1587 (set_message): Drop all but the second arg, which has to be a string.
1588 (set_message_1): Simplify now that we know that a1 is NULL and the
1589 second arg is a string.
1590 * frame.h (struct frame): Remove `message_buf' field.
1591 Use glyphs_initialized_p instead.
1592 (FRAME_MESSAGE_BUF): Remove macro.
1593 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1594 * lisp.h (message2, message2_nolog): Remove declarations.
1595 (message3, message3_nolog): Update declarations.
1596 * keyboard.c (read_char_minibuf_menu_text)
1597 (read_char_minibuf_menu_width): Remove vars.
1598 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1599 to correctly handle multibyte strings.
1600 * frame.c (delete_frame): Don't free message_buf any more.
1601 * editfns.c (message_text, message_length): Remove vars.
1602 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1603 * fileio.c (auto_save_error): Use message3 instead of message2.
1604 * dispnew.c (adjust_frame_message_buffer): Remove function.
1606 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1608 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1609 real estate used for the tool bar and the menu bar.
1611 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1613 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1614 hidden buffer is prepared to modification (Bug#13164).
1616 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1618 * window.h (struct window): Change window_end_valid member from
1619 Lisp_Object to a bitfield. Adjust comments.
1620 (wset_window_end_valid): Remove.
1621 * window.c (adjust_window_count): Clear window_end_valid.
1622 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1623 (Fwindow_line_height, set_window_buffer, Frecenter)
1624 (Fsplit_window_internal, Fdelete_other_windows_internal)
1625 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1626 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1627 * xdisp.c (check_window_end, reconsider_clip_changes)
1628 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1629 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1630 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1632 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1634 * xdisp.c (mark_window_display_accurate): Simplify the loop
1635 assuming that the only one of vchild, hchild or buffer window
1636 slots is non-nil. Call mark_window_display_accurate_1 for
1637 the leaf windows only.
1638 (mark_window_display_accurate_1): Always assume leaf window.
1641 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1643 * emacs.c (Qkill_emacs_hook): Now static.
1645 * fileio.c (Finsert_file_contents): Simplify.
1646 Remove unnecessary assignments and tests.
1648 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1650 * w32.c (acl_set_file): Don't test for errors unless
1651 set_file_security returns FALSE. Avoids spurious errors when
1654 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1656 * fileio.c (Finsert_file_contents): Revert code introduced at
1657 2013-01-18 in favor of the simpler and generally better fix.
1658 Save stack space by removing 'buffer' and reusing 'read_buf'
1661 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1663 * lisp.h (eabs): Define unconditionally (Bug#13419).
1664 The old "#if !defined (eabs)" was an unnecessary revenant of back
1665 when this macro was called "abs". Document 'eabs' better.
1667 2013-01-19 Glenn Morris <rgm@gnu.org>
1669 * fns.c (Frandom): Doc fix.
1671 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1673 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1674 segfault when there are lots of overlays.
1676 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1677 when there are lots of overlays.
1678 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1679 for the details and a way to reproduce.
1681 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1683 * fileio.c: Use O_APPEND to append.
1684 This corresponds better to the natural interpretation of "append",
1685 and avoids the need to open the output file twice, or to invoke
1686 lseek when APPEND is neither nil nor a number.
1687 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1688 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1689 file possibly twice, and lseeking to its end; this avoids the
1690 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1691 at the same time: the combination is never needed and apparently
1692 it doesn't work with DOS_NT.
1694 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1695 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1697 Allow floating-point file offsets.
1698 Problem reported by Vitalie Spinu in
1699 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1700 * fileio.c (emacs_lseek): Remove.
1701 (file_offset): New function.
1702 (Finsert_file_contents, Fwrite_region): Use it.
1704 2013-01-19 Chong Yidong <cyd@gnu.org>
1706 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1707 aborting on Fsignal (Bug#13289).
1709 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1711 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1712 set_file_security as failure due to insufficient privileges.
1713 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1714 (fstat): Return owner and group like 'stat' and 'lstat' do.
1716 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1718 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1719 The bug was observed on Ubuntu operating inside a virtual machine,
1720 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1721 The workaround introduces a race condition on non-buggy hosts,
1722 but it's an unlikely race and anyway there's a nearly identical
1723 nearby race that can't be fixed.
1724 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1726 (Fwrite_region): Test for file system time stamp bug.
1727 (init_fileio): New function.
1728 * lisp.h (init_fileio): Declare it.
1729 * emacs.c (main): Call it.
1731 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1732 and make it more consistent with other stat-failure diagnostics.
1734 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1736 Fix crash when inserting data from non-regular files.
1737 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1738 for the error description produced by valgrind.
1739 * fileio.c (read_non_regular): Rename to read_contents.
1740 Free Lisp_Save_Value object used to pass parameters.
1741 (read_non_regular_quit): Rename to read_contents_quit.
1742 (Finsert_file_contents): Redesign internal file reading loop to adjust
1743 gap and end positions after each read and so help make_gap to work
1744 properly. Do not signal an I/O error too early and so do not leave
1745 not yet decoded characters in a buffer, which was the reason of
1746 redisplay crash. Use list2 to build return value. Adjust comments.
1748 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1750 Close a race when statting and reading files (Bug#13149).
1751 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1752 This avoids a race if the file is renamed between stat and open.
1753 This race is not the problem originally noted in Bug#13149;
1754 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1756 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

1763 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1764 * alloc.c (format_save_value): Rename to make_save_value.
1765 (make_save_pointer): New function.
1766 (record_xmalloc): Use make_save_pointer.
1767 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1768 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1769 Change users of make_save_value to make_save_pointer.
1770 Likewise for format_save_value and make_save_value.
1772 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

1786 (map_keymap_char_table_item): Adjust accordingly.
1787 * fileio.c (non_regular_fd, non_regular_inserted)
1788 (non_regular_nbytes): Remove.
1789 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1790 Use format_save_value to pass parameters to read_non_regular.
1791 (read_non_regular): Use XSAVE_ macros to extract parameters.
1793 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1795 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1797 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1799 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1800 extraction from any Lisp_Save_Value slot. Add type checking.
1801 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1802 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1803 * xselect.c: All users changed.
1805 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

1816 (save_excursion_restore): Use XSAVE_OBJECT.
1818 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1820 Avoid needless casts with XSAVE_POINTER.
1821 * alloc.c (mark_object) [GC_MARK_STACK]:
1822 * dired.c (directory_files_internal_unwind):
1823 * fileio.c (do_auto_save_unwind):
1824 * gtkutil.c (pop_down_dialog):
1825 * keymap.c (map_keymap_char_table_item):
1826 * lread.c (load_unwind):
1827 * nsmenu.m (pop_down_menu):
1828 * print.c (print_object) [GC_MARK_STACK]:
1829 * xfns.c (clean_up_file_dialog):
1830 * xmenu.c (cleanup_widget_value_tree):
1831 Omit casts between XSAVE_POINTER and a pointer type.
1833 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1835 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
1836 * eval.c (eval_sub): Protect `form' from being GCed before its
1837 car and cdr becomes protected with the backtrace entry.
1839 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
1841 Make Lisp_Save_Value more versatile storage for up to four objects.
1842 * lisp.h (toplevel): Enumeration to describe types of saved objects.
1843 (struct Lisp_Save_Value): New layout. Adjust comments.
1844 (XSAVE_POINTER): New macro.
1845 (XSAVE_INTEGER): Likewise.
1846 (allocate_misc): Add prototype.
1847 (free_misc): Likewise.
1848 * alloc.c (allocate_misc): Now global.
1849 (free_misc): Likewise. Adjust comment.
1850 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
1851 (free_save_value): Likewise.
1852 (mark_object): Likewise.
1853 * editfns.c (save_excursion_save): Pack everything within
1854 Lisp_Save_Value and so avoid xmalloc.
1855 (save_excursion_restore): Adjust to match new layout. Use free_misc
1856 because we do not allocate extra memory any more. Add eassert.
1857 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1858 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

1872 Fix SIGDANGER handlers, for AIX (Bug#13408).
1873 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:

1898 (nsfont_list_family): Add block/unblock_input calls.
1899 (nsfont_open): Move block_input earlier. Add unblock_input before early
1901 (nsfont_draw): Add block/unblock_input calls.

1926 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
1928 Avoid unnecessary byte position calculation for the gap movement.
1929 Since all users of move_gap do CHAR_TO_BYTE for other purposes

1940 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1942 * term.c (init_tty): Use them instead of rolling our own code.
1943 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1944 switches from 'signal' to 'pthread_sigmask', which is safer in
1945 multithreaded applications.
1946 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1947 which has already arranged for that.
1948 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1949 This is the main part of the bug fix.

1961 predicate, which is how it's really used now. Adjust comment.
1962 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1963 * buffer.c (buffer_slot_type_mismatch): Remove.
1964 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1965 predicate. Adjust comment.

1968 left-margin-width, right-margin-width, left-fringe-width,
1969 right-fringe-width, scroll-bar-width and buffer-display-count.
1970 Use Qstringp for default-directory, buffer-file-name,
1971 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1972 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1974 * data.c (store_symval_forwarding): Adjust to call the predicate.
1976 2013-01-09 Juanma Barranquero <lekktu@gmail.com>

1990 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1991 (make_gap_1): New function to adjust the gap of any buffer.
1992 * coding.c (coding_alloc_by_making_gap): Use it.
1993 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
1994 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.

2017 trailing dash is properly added.
2019 2013-01-05 Eli Zaretskii <eliz@gnu.org>
2021 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
2022 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
2023 digits for buffer positions, before misalignment starts.
2024 Display "0" for integer "object" field.
2025 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2026 Display the newline glyph more unambiguously.
2028 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2030 * nsterm.m (ns_draw_underwave):
2031 * w32term.c (w32_draw_underwave):
2032 * xterm.c (x_draw_underwave): Make underwave look more triangular
2033 and also degrade gracefully for small fonts. (Bug#13000)
2035 * nsterm.m (ns_draw_text_decoration):
2036 * w32term.c (x_draw_glyph_string):
2037 * xterm.c (x_draw_glyph_string): Don't use previous underline
2038 thickness and position if previous underline type is underwave.
2040 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
2042 * fileio.c (Ffile_acl): Undocument return format.
2044 2013-01-02 Glenn Morris <rgm@gnu.org>
2046 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

2056 * lread.c (read_list):
2057 * minibuf.c (Ftry_completion):
2058 * term.c (tty_ins_del_lines):
2059 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2060 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2062 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2064 * w32.c (unsetenv): Set up the string passed to _putenv
2066 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
2067 for the bug this caused.
2069 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
2071 * coding.c (Qmac): Now static.
2073 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2075 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
2076 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

2080 (update_frame_tool_bar): Check toolbar_is_packed for packing.
2081 Show all on TOOLBAR_TOP_WIDGET.
2082 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
2083 by TOOLBAR_TOP_WIDGET.
2084 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
2085 Check toolbar_is_packed.
2086 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
2087 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2088 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
2090 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2091 (xg_update_menubar): Update title only if
2092 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2093 (xg_update_submenu): Skip tearoff only if
2094 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2095 (xg_initialize): Initialize xg_detached_menus only if
2096 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2098 * xterm.h (struct x_output): Surround handlebox_widget with
2099 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2100 toolbar_in_hbox is bool.
2102 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2104 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2105 (LIBS_GNUSTEP): Define.
2106 (LIBES): Add $(LIBS_GNUSTEP).

2109 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2111 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2112 continuation glyph on a TTY with an indication of an empty line.
2115 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2117 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2118 file's SELinux context or ACLs successfully set, nil otherwise.
2120 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.

2123 SetEvent and WaitForSingleObject.
2125 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2127 Port EXTERNALLY_VISIBLE to Clang 3.2.
2128 * conf_post.h (__has_attribute): New macro.
2129 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2131 2012-12-27 Glenn Morris <rgm@gnu.org>
2133 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2134 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2136 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2138 * fileio.c (file_name_as_directory, directory_file_name):
2139 Accept an additional argument MULTIBYTE to indicate whether the input C
2140 came from a multibyte or a unibyte Lisp string; all callers
2141 adjusted. Don't assume the input string is always multibyte.
2143 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2144 don't ENCODE_FILE them, and return a unibyte string if the input
2146 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2147 don't assume the input strings will always be multibyte. If the
2148 input strings are multibyte, decode strings obtained from C
2151 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2153 * lisp.h (toplevel): Add two notices to the comment about
2154 defining a new Lisp data type.

2158 * alloc.c (valid_lisp_object_p): Adjust comment.
2160 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2162 * keyboard.c (record_asynch_buffer_change): Initialize an event
2163 only if it's really needed.
2164 * frame.h (enum output_method): Remove output_mac member since
2165 it's a leftover from the deleted code.
2166 * frame.c (Fframep): Adjust user here ...
2167 * terminal.c (Fterminal_live_p): ... and here.
2168 * coding.c (Qmac): Now here because it's only used to denote
2169 end-of-line encoding type.
2170 (syms_of_coding): DEFSYM it.
2171 * frame.h (Qmac): Remove duplicated declaration.
2173 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2175 * window.c (select_window_1): Now static, since it's used only here.
2177 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2179 * window.c (window_body_cols): Subtract display margins from the
2180 window body width on TTYs as well. See
2181 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2182 for the original report.
2184 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2186 * xdisp.c (redisplay_window): Remove inner local variable
2187 because the outer shadowed one has the same meaning.
2188 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2190 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2191 (xg_create_tool_bar): Adjust users.
2193 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2195 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2196 * buffer.c (Fget_buffer_create): Use it to set compact field of
2197 struct buffer_text to avoid accessing an uninitialized value
2198 when compact_buffer is called for the first time.
2199 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2200 (Fset_buffer_modified_p): Use buffer_window_count to check
2201 whether the buffer is displayed in some window.
2202 * xdisp.c (message_dolog): Likewise.
2204 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2206 * w32.c (acl_set_file): If setting the file security descriptor
2207 fails, and the new DACL is identical to the existing one, silently
2208 return success. This fixes problems for users backing up their
2209 own files without having the necessary privileges for setting
2210 security descriptors.
2212 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2214 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2215 after WaitForSingleObject returns normally. This expedites reader
2216 thread shutdown when delete_child triggers it.
2217 (reap_subprocess): More accurate commentary for why we call
2218 delete_child only when cp->fd is negative.
2220 * w32.c (sys_close): Do not call delete_child on a subprocess
2221 whose handle is not yet closed. Instead, set its file descriptor
2222 to a negative value, so that reap_subprocess will call
2223 delete_child on that subprocess when its SIGCHLD arrives.
2224 This avoids closing handles used for communications between sys_select
2225 and reader_thread, which doesn't give sys_select a chance to
2226 notice that the process exited and invoke the SIGCHLD handler for
2229 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2231 * nsfns.m (Fns_do_applescript): Run event loop until script has
2232 been executed (Bug#12969).

2238 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2240 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2242 * w32term.c (w32fullscreen_hook): New function.
2243 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2245 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2247 * fileio.c (Finsert_file_contents): Doc fix.
2249 * w32proc.c (new_child, delete_child, find_child_pid): For a
2250 subprocess, consider its slot being in use as long as its process
2251 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2252 slot when a new process is started immediately after killing
2253 another one, without waiting enough time for the first process to
2254 be reaped and resources allocated for it be orderly freed.
2256 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2258 2012-12-21 Chong Yidong <cyd@gnu.org>
2260 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2262 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2264 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2266 * w32.c (get_name_and_id): Always pass NULL as the first argument
2267 of lookup_account_sid. Avoids crashes with UNC file names that
2268 refer to DFS domains, not to specific machine names. (Bug#12621)
2269 Remove now unused argument FNAME; all callers changed.
2270 (get_file_owner_and_group): Remove now unused argument FNAME; all
2273 2012-12-21 Chong Yidong <cyd@gnu.org>
2275 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2276 error for invalid chars, don't check for a nil return value.
2278 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2280 Avoid calls to CHAR_TO_BYTE if byte position is known.
2281 * editfns.c (make_buffer_string_both): Use move_gap_both.
2282 (Fbuffer_string): Use make_buffer_string_both.
2283 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2285 (buf_bytepos_to_charpos): Likewise.
2286 (charpos_to_bytepos): Remove.
2287 * fileio.c (Finsert_file_contents): Use move_gap_both.
2288 * search.c (Freplace_match): Likewise.
2289 * process.c (process_send_region): Likewise. Use convenient
2290 names for byte positions.
2291 * lisp.h (charpos_to_bytepos): Remove prototype.
2292 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2293 * insdel.c (move_gap): Likewise.
2295 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2297 * xdisp.c (redisplay_internal): Remove now-unused local.
2299 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2301 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2302 (redisplay_internal): Don't bother selecting the frame to get the
2303 proper value of frame-local variables (bug#13225).
2305 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2307 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2308 Rename 4th argument since it may be buffer or string. Adjust comment.
2309 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2311 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2313 * coding.c (Fdetect_coding_region): Do not check start and end with
2314 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2315 (code_convert_region): Likewise.
2317 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2319 * w32.c (acl_get_file, acl_set_file): Run the file name through
2320 map_w32_filename, and resolve any symlinks in the file name, like
2322 (acl_set_file): Call revert_to_self, if any privileges were
2325 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2327 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2328 ($(BLD)/w32.$(O)): Update dependencies.
2330 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2332 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2333 propagate redisplay's scrolling (if any) to the right window.

2366 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2367 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2368 for some of that bug's symptoms can now cause Emacs to abort.
2369 Remove the workaround.
2370 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2371 The bug that caused SIGCHLD to get lost has been fixed, and the
2372 workaround for it can now cause Emacs to abort.
2374 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2376 * sysdep.c (emacs_abort): Bump backtrace size to 40.

2384 and copy ACL entries of file in addition to SELinux context if set.
2385 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2387 * Makefile.in (LIBACL_LIBS): New macro.

2402 * w32proc.c (new_child): Initialize input_file and
2403 pending_deletion members of the child.

2405 that is pending deletion.
2406 (register_child): First argument is now pid_t.
2407 (record_infile, record_pending_deletion): New functions.

2409 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2411 * fileio.c (internal_delete_file): Return an int again: non-zero

2416 * callproc.c (Fcall_process): Don't overwrite infile with result
2418 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2419 asynchronous subprocess, record the name of the input file name,
2421 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2422 delete the file, record it as pending deletion when the subprocess
2425 2012-12-14 Eli Zaretskii <eliz@gnu.org>

2445 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2447 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2448 try to get accurate owner and group information from NT file
2449 security APIs. This is to make most callers of 'stat' and
2450 'lstat', which don't need that information, much faster.
2452 * dired.c (Ffile_attributes) [WINDOWSNT]:
2453 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2454 owner and group information from 'lstat'.
2456 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2458 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2459 as that confuses set-auto-coding, so insist on the head-read
2460 returning the full 1024 bytes. Let lseek compute the tail offset;

2485 files, fixing a regression from 24.2.
2486 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2488 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2490 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2491 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2492 Remove unnecessary S_ISLNK test, as (contra the comments) this
2493 function can't copy symlinks. Improve quality of error message
2494 when attempting to copy files that are neither regular files nor

2513 * inotify.c (inotify_callback): Generate an Emacs event for every
2514 incoming inotify event.
2516 2012-12-11 Eli Zaretskii <eliz@gnu.org>

2808 * frame.c (make_frame): Use it. Adjust comment.
2809 * buffer.c (candidate_buffer): New function.
2810 (Fother_buffer, other_buffer_safely): Use it.
2812 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2814 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2815 if the child process is still running. Instead, exit the wait
2816 loop and return zero. (Bug#13086)
2818 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2820 * frame.h (x_char_width, x_char_height): Remove prototypes.

2831 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
2833 Fix a recently-introduced delete-process race condition.
2834 * callproc.c, process.h (record_kill_process):
2835 New function, containing part of the old call_process_kill.
2836 (call_process_kill): Use it.
2837 This does not change call_process_kill's behavior.
2838 * process.c (Fdelete_process): Use record_kill_process to fix a
2839 race condition that could cause Emacs to lose track of a child.
2841 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2843 Avoid code duplication between prev_frame and next_frame.
2844 * frame.c (candidate_frame): New function. Add comment.
2845 (prev_frame, next_frame): Use it. Adjust comment.
2847 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2849 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2850 fails, signal an error instead of continuing with an empty
2852 Encode expanded temp file pattern before passing it to mkstemp or
2855 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2856 Encode the file name before passing it to dostounix_filename, in
2857 case it will downcase it (under w32-downcase-file-names).
2860 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2862 Minor call-process cleanups.
2863 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2864 at the same time as other platforms, to simplify analysis.
2865 No need for fd0_volatile since we have synch_process_fd.
2866 Avoid needless emacs_close; arg is always negative.
2868 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2870 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2873 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2875 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2876 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2877 and mouse_face_hidden members to a bitfields.
2878 * frame.h (struct frame): Remove set-but-not-used space_width member.
2879 (FRAME_SPACE_WIDTH): Remove.
2880 * nsterm.m, w32term.c, xterm.c: Adjust users.
2881 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2882 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2883 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2884 members to a bitfields.
2886 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2888 Don't let call-process be a zombie factory (Bug#12980).
2889 Fixing this bug required some cleanup of the signal-handling code.
2890 As a side effect, this change also fixes a longstanding rare race
2891 condition whereby Emacs could mistakenly kill unrelated processes,
2892 and it fixes a bug where a second C-g does not kill a recalcitrant
2893 synchronous process in GNU/Linux and similar platforms.
2894 The patch should also fix the last vestiges of Bug#9488,
2895 a bug which has mostly been fixed on the trunk by other changes.
2896 * callproc.c, process.h (synch_process_alive, synch_process_death)
2897 (synch_process_termsig, sync_process_retcode):
2898 Remove. All uses removed, to simplify analysis and so that
2899 less consing is done inside critical sections.
2900 * callproc.c (call_process_exited): Remove. All uses replaced
2901 with !synch_process_pid.
2902 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2903 These take the role of what used to be in unwind-protect arg.
2905 (block_child_signal, unblock_child_signal):
2906 New functions, to avoid races that could kill innocent-victim processes.
2907 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2908 (call_process_kill): Record killed processes as deleted, so that
2909 zombies do not clutter up the system. Do this inside a critical
2910 section, to avoid a race that would allow the clutter.
2911 (call_process_cleanup): Fix code so that the second C-g works again
2912 on common platforms such as GNU/Linux.
2913 (Fcall_process): Create the child process in a critical section,
2914 to fix a race condition. If creating an asynchronous process,
2915 record it as deleted so that zombies do not clutter up the system.
2916 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2917 light of these changes. Omit unnecessary call to emacs_close
2918 before failure, as the unwind-protect code does that.
2919 * callproc.c (call_process_cleanup):
2920 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2921 * process.c (record_deleted_pid): New function, containing
2922 code refactored out of Fdelete_process.
2923 (Fdelete_process): Use it.
2924 (process_status_retrieved): Remove. All callers changed to use
2925 child_status_change.
2926 (record_child_status_change): Remove, folding its contents into ...
2927 (handle_child_signal): ... this signal handler. Now, this
2928 function is purely a handler for SIGCHLD, and is not called after
2929 a synchronous waitpid returns; the synchronous code is moved to
2930 wait_for_termination. There is no need to worry about reaping
2931 more than one child now.
2932 * sysdep.c (get_child_status, child_status_changed): New functions.
2933 (wait_for_termination): Now takes int * status and bool
2934 interruptible arguments, too. Do not record child status change;
2935 that's now the caller's responsibility. All callers changed.
2936 Reimplement in terms of get_child_status.
2937 (wait_for_termination_1, interruptible_wait_for_termination):
2938 Remove. All callers changed to use wait_for_termination.
2939 * syswait.h: Include <stdbool.h>, for bool.
2940 (record_child_status_change, interruptible_wait_for_termination):
2942 (record_deleted_pid, child_status_changed): New decls.
2943 (wait_for_termination): Adjust to API changes noted above.
2945 * bytecode.c, lisp.h (Qbytecode): Remove.
2946 No longer needed after 2012-11-20 interactive-p changes.
2948 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2950 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2951 the scroll margin, move point outside the margin. (Bug#13055)
2953 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2955 * gtkutil.c (my_log_handler): New function.
2956 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2958 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2960 * lisp.h (modify_region): Rename to...
2961 (modify_region_1): ...new prototype.
2962 * textprop.c (modify_region): Now static. Adjust users.
2963 * insdel.c (modify_region): Rename to...
2964 (modify_region_1): ...new function to work with current buffer.
2965 Adjust comment and users. Use true and false for booleans.
2967 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2969 * alloc.c (free_save_value): New function.
2970 (safe_alloca_unwind): Use it.
2971 * lisp.h (free_save_value): New prototype.
2972 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2974 (save_excursion_restore): Adjust to match saved data structure.
2975 Use free_save_value to offload some work from GC. Drop obsolete
2978 2012-12-03 Chong Yidong <cyd@gnu.org>
2980 * fileio.c (Vauto_save_list_file_name): Doc fix.
2982 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2984 * w32fns.c: Remove prototype of atof.
2985 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2987 (file_dialog_callback): Make it UINT_PTR.
2989 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2992 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2993 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2996 2012-12-03 Glenn Morris <rgm@gnu.org>
2998 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3000 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3002 Fix xpalloc confusion after memory is exhausted.
3003 * alloc.c (xpalloc): Comment fix.
3004 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3005 and signals an error, do not clear charset_table_size, as
3006 charset_table is still valid.
3007 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3009 Use execve to avoid need to munge environ (Bug#13054).
3010 * callproc.c (Fcall_process):
3011 * process.c (create_process):
3012 Don't save and restore environ; no longer needed.
3013 * callproc.c (child_setup):
3014 Use execve, not execvp, to preserve environ.
3016 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3018 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3020 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3022 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3023 display for sliced images (Bug#10500).
3025 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3027 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3029 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3030 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3032 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3034 * xdisp.c (window_outdated): Remove eassert since it hits
3035 some suspicious corner cases (see Bug#13007 and Bug#13012).
3036 (mode_line_update_needed): New function.
3037 (redisplay_internal, redisplay_window): Use it.
3038 (ensure_selected_frame): New function.
3039 (redisplay_internal, unwind_redisplay): Use it.

3041 (buffer_shared_and_changed): ...near to its real use.
3043 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3045 * callproc.c (Fcall_process): Don't misreport vfork failure.
3047 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3049 * callproc.c (Fcall_process): Fix vfork portability problems.
3050 Do not assume that fd[0], count, filefd, and save_environ survive
3051 vfork. Fix bug whereby wrong errno value could be reported for
3052 pipe failure. Some minor cleanups, too, as follows. Move buf and
3053 bufsize to the context where they're needed. Change new_argv to
3054 be of type char **, as this is more convenient and avoids casts.
3055 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3056 Now local constants, not macros.
3058 2012-11-18 Kenichi Handa <handa@gnu.org>
3060 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3061 for the variable "f".
3063 2012-11-13 Kenichi Handa <handa@gnu.org>
3065 * font.c (font_unparse_xlfd): Exclude special characters from the
3066 generating XLFD name.
3068 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

3104 were always defined.
3106 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3108 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3109 between bpos_covered and bpos_max. This fixes cursor display when
3110 several display strings follow each other.
3112 * .gdbinit (pgx): If the glyph's object is a string, display the
3113 pointer to string data, rather than the value of the string object
3114 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3116 * indent.c (Fvertical_motion): If the starting position is covered
3117 by a display string, return to one position before that, to avoid
3118 overshooting it inside move_it_to. (Bug#12930)
3120 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

3139 of a literal "/". (Bug#12955)
3140 (gl-stamp): Invoke fc.exe directly, not through cmd.

3145 * dired.c: Assume HAVE_DIRENT_H.
3146 (NAMLEN): Remove, replacing with ...
3147 (dirent_namelen): New function. All uses changed. Use the GNU macro
3148 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3149 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3150 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3151 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3153 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3154 * ndir.h: Rename to ../nt/inc/dirent.h.
3155 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3156 Do not include <dirent.h>; no longer needed.
3157 * w32.c: Include <dirent.h> rather than "ndir.h".
3159 2012-11-23 Chong Yidong <cyd@gnu.org>
3161 * xftfont.c (xftfont_open): Remove duplicate assignment.
3163 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3165 * alloc.c (Fgarbage_collect): Unblock input after clearing
3166 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3167 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3168 * msdos.c (IT_frame_up_to_date): Use it here...
3169 * w32term.c (w32_frame_up_to_date): ...here...
3170 * xterm.c (XTframe_up_to_date): ...and here...
3171 * nsterm.m (ns_frame_up_to_date): ...but not here.
3172 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3174 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3175 Do not check whether GC is in progress.

3179 * xdisp.c (window_buffer_changed): New function.
3180 (update_menu_bar, update_tool_bar): Use it to
3181 simplify large 'if' statements.

3183 'tail' and 'frame' local variables.
3185 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3187 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3188 with Windows system header.
3190 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3192 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).

3209 * emacs.c (main): Set the G_SLICE environment variable for all
3210 Cygwin builds, not just GTK builds. See
3211 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3213 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3215 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3216 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3217 Define for the MSVC compiler.
3219 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3221 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3222 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3223 dostounix_filename. Prevents crashes down the road, because
3224 dostounix_filename assumes it gets a unibyte string.
3225 Reported by Michel de Ruiter <michel@sentient.nl>, see

3264 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3265 cygwin_convert_file_name*.
3267 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3268 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3270 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3272 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3274 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3276 * w32select.c: Include w32common.h before w32term.h, so that
3277 windows.h gets included before w32term.h uses some of its
3278 features, see below.
3280 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3282 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3284 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3286 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3288 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3289 (ns_select): Return at once if events are held (Bug#12834).
3291 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3293 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3294 Needed following 2012-10-20 change. (Bug#12902)
3296 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3298 * w32proc.c (waitpid): Remove unused label get_result.
3300 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3302 * makefile.w32-in (SYSWAIT_H): New macro.
3303 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3304 ($(BLD)/sysdep.$(O)): Update dependencies.
3306 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3308 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3309 * callproc.c (relocate_fd): Assume F_DUPFD.
3310 * emacs.c, term.c (O_RDWR): Remove.
3311 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3312 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3313 * nsterm.m: Assume <fcntl.h> exists.
3314 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3315 (create_pty, Fmake_network_process, server_accept_connection)
3316 (wait_reading_process_output, init_process_emacs):
3318 (wait_reading_process_output): Put in a special case for WINDOWSNT
3319 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3320 It's not clear this is needed, but it's a more-conservative change.
3321 (create_process): Assume FD_CLOEXEC.
3322 (create_process, create_pty): Assume O_NOCTTY.
3323 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3324 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3325 Omit if not DOS_NT, since F_GETFL is not defined there.
3326 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3327 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3329 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3330 lack it, since gnulib guarantees this.
3331 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3333 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3335 * w32.c (faccessat): Pretend that directories have the execute bit
3336 set. Emacs expects that, e.g., in files.el:cd-absolute.
3338 * w32proc.c (create_child): Don't clip the PID of the child
3339 process to fit into an Emacs integer, as this is no longer a
3341 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3342 reaping only the process specified by PID argument, if that is
3343 positive. Use PID instead of dead_child to know which process to
3344 reap. Wait for the child to die only if WNOHANG is not in
3346 (sys_select): Don't set dead_child.
3348 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3349 as it is no longer needed.
3351 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3353 (record_child_status_change): Remove the setting of
3354 record_at_most_one_child for the !WNOHANG case.
3356 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3358 Fix problems in ns port found by static checking.
3359 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3360 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3361 not to process group.
3362 (ns_select): Use emacs_write, not write, as that's more robust
3363 in the presence of signals.
3364 (fd_handler:): Check for read errors.
3366 2012-11-16 Glenn Morris <rgm@gnu.org>
3368 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3370 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3372 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3374 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3376 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3377 use the same value of thread handle.
3378 (start_timer_thread): If the timer thread exited (due to error),
3379 clean up by closing the two handles it used. Duplicate the caller
3380 thread's handle here, so it gets duplicated only once, when
3381 launching the timer thread. Set priority of the timer thread, not
3383 (getitimer): Don't duplicate the caller thread's handle here.
3386 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3388 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3391 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3393 Remove no-longer-used pty_max_bytes variable.
3394 * process.c (pty_max_bytes): Remove; unused.
3395 (send_process): Do not set it.
3397 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3399 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3400 Update dependencies.
3402 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3404 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3405 This follows up on the 2012-09-29 patch that removed indirection
3406 for the 'function' field. Reported by Sergey Vinokurov in
3407 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3409 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3411 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3412 different name, as the MS runtime does not have such a function,
3413 and probably never will.) All callers changed. Ignore DIRFD
3414 value if PATH is an absolute file name, to match Posix spec
3415 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3418 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3420 * xdisp.c (echo_area_display, redisplay_internal):
3421 Omit redundant check whether frame_garbaged is set.
3423 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3425 Use faccessat, not access, when checking file permissions (Bug#12632).
3426 This fixes a bug that has been present in Emacs since its creation.
3427 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3428 which must set some sort of record. (Torek's bug report was against
3429 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3430 same common flaw.) See Torek's Usenet posting
3431 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3432 Posted: Fri Apr 8 14:18:56 1983.
3433 * Makefile.in (LIB_EACCESS): New macro.
3435 * callproc.c (init_callproc):
3436 * charset.c (init_charset):
3437 * fileio.c (check_existing, check_executable, check_writable)
3439 * lread.c (openp, load_path_check):
3440 * process.c (allocate_pty):
3442 Use effective UID when checking permissions, not real UID.
3443 * callproc.c (init_callproc):
3444 * charset.c (init_charset):
3445 * lread.c (load_path_check, init_lread):
3446 Test whether directories are accessible, not merely whether they exist.
3447 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3448 * fileio.c (check_existing, check_executable, check_writable)
3450 Use symbolic names instead of integers for the flags, as they're
3452 (check_writable): New arg AMODE. All uses changed.
3453 Set errno on failure.
3454 (Ffile_readable_p): Use faccessat, not stat + open + close.
3455 (Ffile_writable_p): No need to call check_existing + check_writable.
3456 Just call check_writable and then look at errno. This saves a syscall.
3457 dir should never be nil; replace an unnecessary runtime check
3458 with an eassert. When checking the parent directory of a nonexistent
3459 file, check that the directory is searchable as well as writable, as
3460 we can't create files in unsearchable directories.
3461 (file_directory_p): New function, which uses 'stat' on most platforms
3462 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3463 (Ffile_directory_p, Fset_file_times): Use it.
3464 (file_accessible_directory_p): New function, which uses a single
3465 syscall for efficiency.
3466 (Ffile_accessible_directory_p): Use it.
3467 * xrdb.c (file_p): Use file_directory_p.
3468 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3469 * lread.c (openp): When opening a file, use fstat rather than
3470 stat, as that avoids a permissions race. When not opening a file,
3471 use file_directory_p rather than stat.
3472 (dir_warning): First arg is now a usage string, not a format.
3473 Use errno. All uses changed.
3474 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3475 that merely introduced a race.
3476 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3477 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3478 and similarly for the other O_* flags.
3479 * w32.c (sys_faccessat): Rename from sys_access and switch to
3480 faccessat's API. All uses changed.
3481 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3482 (magic_db): Rename from magic_file_p.
3483 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3484 char *, so that we don't have to test for file existence
3485 separately from opening the file for reading. This removes a race
3486 fixes a permission-checking problem, and simplifies the code.
3488 (file_p): Remove; no longer needed.
3490 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3492 Omit glyphs initialization at startup.
3493 * dispnew.c (glyphs_initialized_initially_p): Remove.
3494 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3495 (Fredraw_frame): Move actual code from here...
3496 (redraw_frame): ...to here. Add eassert. Adjust comment.
3497 (Fredraw_display): Use redraw_frame.
3498 * xdisp.c (clear_garbaged_frames): Likewise.
3500 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3502 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3503 passed to pint2str and pint2hrstr to be at most the size of the
3504 frame's decode_mode_spec_buffer. This avoids crashes with very
3505 large values of FIELD_WIDTH argument to decode_mode_spec.
3508 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3510 Fix a race with verify-visited-file-modtime (Bug#12863).
3511 Since at least 1991 Emacs has ignored an mtime difference of no
3512 more than one second, but my guess is that this was to work around
3513 file system bugs that were fixed long ago. Since the race is
3514 causing problems now, let's remove that code.
3515 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3516 whose time stamp is off by no more than a second. Insist that the
3517 file time stamps match exactly.
3519 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3521 * frame.h (struct frame): Convert external_tool_bar member to
3522 1-bit unsigned bitfield.
3523 * termhooks.h (struct terminal): Remove mouse_moved member since
3524 all users are long dead. Adjust comment on mouse_position_hook.
3526 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3528 Simplify by using FOR_EACH_FRAME here and there.
3529 * frame.c (next_frame, prev_frame, other_visible_frames)
3530 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3531 * w32term.c (x_window_to_scroll_bar): Likewise.
3532 * window.c (window_list): Likewise.
3533 * xdisp.c (x_consider_frame_title): Likewise.
3534 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3535 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3536 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3537 * xmenu.c (menubar_id_to_frame): Likewise.
3538 * xselect.c (frame_for_x_selection): Likewise.
3539 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3540 (x_window_to_menu_bar): Likewise.
3541 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3543 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3545 * data.c (Qdefalias_fset_function): Now static.
3547 Another tweak to vectorlike_header change.
3548 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3549 Remove, and replace all uses with ...
3550 (next_in_free_list, set_next_in_free_list):
3551 New functions, which respect C's aliasing rules better.
3553 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3555 * window.c (list4i): Rename from 'quad'. All uses changed.
3556 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3558 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3560 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3561 warning about mixing declarations and code in ISO C90.
3563 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3565 * window.c (Fsplit_window_internal): Set combination limit of
3566 new parent window to t iff Vwindow_combination_limit is t;
3567 fixing a regression introduced with the change from 2012-09-22.
3568 (Fset_window_combination_limit): Fix doc-string.
3570 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3572 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3573 amount when the scroll margins are too large. When scrolling
3574 backwards in the buffer, give up if cannot reach point or the
3575 scroll margin within a reasonable number of screen lines.
3576 Fixes point position in window under scroll-up/down-aggressively when
3577 point is positioned many lines beyond the window top/bottom.
3580 * ralloc.c (relinquish): If real_morecore fails to return memory
3581 to the system, don't crash; instead, leave the last heap
3582 unchanged and return. (Bug#12774)
3584 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3586 * lisp.h (AUTOLOADP): New macro.
3587 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3588 * data.c (Ffset): Remove special ad-advice-info handling.
3589 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3591 (Finteractive_form): Simplify.
3592 (Fquo): Don't insist on having at least 2 arguments.
3593 (Qdefalias_fset_function): New var.
3595 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3597 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

3601 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3603 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3605 Fix recently introduced crash on MS-Windows (Bug#12839).
3606 * w32term.h (struct scroll_bar): Use convenient header.
3607 (SCROLL_BAR_VEC_SIZE): Remove.
3608 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3610 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3612 Tweak last vectorlike_header change.
3613 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3614 vectorlike object on the free list. This is introduced to avoid
3615 some (but not all) pointer casting and aliasing problems, see
3616 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3617 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3619 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3621 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3623 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3624 been removed, so remove them here also.
3626 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3628 * doc.c (Fdocumentation): Handle new property
3629 dynamic-docstring-function to replace the old ad-advice-info.
3631 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3633 * fns.c (Qeql, hashtest_eq): Now static.
3635 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3637 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3638 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3639 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
3640 * buffer.c (compare_overlays): Use XLI rather than XHASH.
3642 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
3644 Use same hash function for hashfn_profiler as for hash_string etc.
3645 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3646 * lisp.h (sxhash_combine): New inline function, with the contents
3647 of the old SXHASH_COMBINE.
3648 * profiler.c (hashfn_profiler): Use it, instead of having a
3649 special hash function containing a comparison that always yields 1.
3651 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3653 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3654 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3655 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3658 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3660 * image.c (xpm_make_color_table_h): Fix compiler error because
3661 make_hash_table changed.
3663 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3665 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3667 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3669 Use ad-hoc comparison function for the profiler's hash-tables.
3670 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3671 (make_log): Use them.
3672 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3673 call Fequal any more.

3682 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3683 (hash_lookup, hash_remove_from_table): Move assertion checking of
3684 hashfn result here. Check hash-equality before calling cmpfn.
3685 (Fmake_hash_table): Adjust call to make_hash_table.
3686 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
3687 (syms_of_fns): Initialize them.

3691 * print.c (print_object): Adjust to new hash-table struct.
3692 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
3694 2012-11-08 Eli Zaretskii <eliz@gnu.org>
3696 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3697 value of w32-scroll-lock-modifier is neither nil nor one of the
3698 known key modifiers. (Bug#12806)
3700 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3702 Shrink struct vectorlike_header to the only size field.
3703 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3705 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3706 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3707 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3708 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3709 information from the vector header. Adjust comment.
3710 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
3711 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
3713 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
3714 (struct vectorlike_header): Remove next member. Adjust comment.
3715 (struct Lisp_Subr): Add convenient header. Adjust comment.
3716 (allocate_pseudovector): Adjust prototype.
3717 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
3718 (sweep_string, lisp_malloc): Remove useless prototypes.
3719 (enum mem_type): Adjust comment.
3720 (NEXT_IN_FREE_LIST): New macro.
3721 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3722 (Fmake_bool_vector): Likewise.
3723 (struct large_vector): New type to represent allocation unit for
3724 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3725 (large_vectors): Change type to struct large_vector.
3726 (allocate_vector_from_block): Simplify.
3727 (PSEUDOVECTOR_NBYTES): Replace with...
3728 (vector_nbytes): ...new function. Adjust users.
3729 (sweep_vectors): Adjust processing of large vectors.
3730 (allocate_vectorlike): Likewise.
3731 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3732 Add easserts. Adjust XSETPVECTYPESIZE usage.
3733 (allocate_buffer): Use BUFFER_PVEC_INIT.
3734 (live_vector_p): Adjust to match large vector.
3735 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3736 * buffer.h (struct buffer): Add next member.
3737 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3739 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
3740 * fns.c (internal_equal): Adjust to match enum pvec_type change.
3741 (copy_hash_table): Adjust to match vector header change.
3742 * lread.c (defsubr): Use XSETPVECTYPE.
3743 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
3744 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
3745 (xvecsize): New command.
3747 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3749 * keyboard.c (event_to_kboard): Do not dereference
3750 frame_or_window field of SELECTION_REQUEST_EVENT
3751 and SELECTION_CLEAR_EVENT events (Bug#12814).
3752 * xterm.h (struct selection_input_event): Adjust comment.
3754 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3756 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3757 such as Scroll Lock, if the respective keys are treated as
3758 function keys, not as modifiers. This avoids destroying non-ASCII
3759 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3761 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3763 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3765 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3767 Restore some duplicate definitions (Bug#12814).
3768 This undoes part of the 2012-11-03 changes. Some people build
3769 with plain -g rather than with -g3, and they need the duplicate
3770 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3771 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3772 Define as macros, as well as as enums or as constants.
3774 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3776 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3777 to keypad keys (Bug#12816).
3779 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3781 Minor adjustments of recently-changed frame functions.
3782 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3783 known to be a frame (we're in the FRAMEP branch).
3784 * lisp.h (Qframep): Remove decl. frame.h declares this.
3785 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3786 since they're meant for Lisp fixnum values.
3788 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3790 * window.c (Fwindow_combination_limit): Revert to the only
3791 required argument and adjust docstring as suggested in
3792 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3793 by Martin Rudalics <rudalics@gmx.at>.
3795 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3797 Widely used frame validity and checking functions.
3798 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3799 * frame.c (decode_live_frame, decode_any_frame): New functions.
3800 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3801 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3802 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3803 (Fframe_pointer_visible_p): Use decode_any_frame.
3804 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
3805 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
3806 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3807 (Fframe_focus): Likewise. Allow zero number of arguments.
3809 (frame_buffer_list, frame_buffer_predicate): Remove.
3810 * lisp.h (frame_buffer_predicate): Remove prototype.
3811 * buffer.c (Fother_buffer): Use decode_any_frame.
3812 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3813 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3814 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3815 (Fclose_font, Ffont_info): Use decode_live_frame.
3816 * fontset.c (check_fontset_name): Likewise.
3817 * terminal.c (Fframe_terminal): Likewise.
3818 * w32fns.c (check_x_frame): Likewise.
3819 * window.c (Fminibuffer_window, Fwindow_at)
3820 (Fcurrent_window_configuration): Likewise.
3821 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3822 Likewise. Allow zero number of arguments. Adjust docstring.
3823 * dispnew.c (Fredraw_frame): Likewise.
3824 * xfaces.c (frame_or_selected_frame): Remove.
3825 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3826 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3827 (Fframe_face_alist): Use decode_live_frame.
3828 * xfns.c (check_x_frame): Likewise.
3830 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3832 * window.c (quad): New function.
3833 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3834 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3835 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3836 (Fwindow_line_height): Use it.
3837 (Fwindow_fringes): Use list3.
3838 (Fwindow_scroll_bars): Use list4.
3839 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3840 (Fwindow_combination_limit): Allow zero number of arguments.
3842 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3844 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3846 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3847 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3848 file descriptor 2 for standard error. (Bug#12805)
3850 2012-11-05 Chong Yidong <cyd@gnu.org>
3852 * process.c (wait_reading_process_output): Revert previous change.
3854 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3856 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3857 This removes code that has been obsolete since around 1990.
3858 * callproc.c (Fcall_process):
3860 * process.c (create_process):
3861 * term.c (dissociate_if_controlling_tty):
3862 Assume setsid exists.
3863 * callproc.c (child_setup): Assume setpgid exists and behaves as
3864 per POSIX.1-1988 or later.
3865 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3866 * emacs.c (shut_down_emacs):
3867 * sysdep.c (sys_suspend, init_foreground_group):
3868 Assume getpgrp behaves as per POSIX.1-1998 or later.
3869 * msdos.c (setpgrp): Remove.
3870 (tcgetpgrp, setpgid, setsid): New functions.
3871 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3872 * term.c (no_controlling_tty): Remove; unused.
3873 * w32proc.c (setpgrp): Remove.
3874 (setsid, tcgetpgrp): New functions.
3876 Simplify by assuming __fpending.
3877 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3878 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3879 Do not assume that __fpending's result fits in int.
3881 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3883 Remove EMACS_OUTQSIZE+sleep hack.
3884 * dispnew.c (update_frame_1): Remove hack for terminals slower
3885 than 2400 bps, which throttled Emacs by having it sleep.
3886 This code hasn't worked since at least 2007, when the multi-tty stuff
3887 was added, and anyway those old terminals are long dead.
3888 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3889 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3891 Fix data-loss with --version (Bug#9574).
3892 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3893 as we can't assume that emacs_strerror is initialized, and strerror
3894 is good enough here.
3895 (main): Invoke atexit earlier, to catch earlier instances of
3896 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3898 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3900 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3901 (keyDown): Remap keypad keys to X11 virtual key codes.
3903 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3905 Fix data-loss with --batch (Bug#9574).
3906 * emacs.c: Include <close-stream.h>.
3907 (close_output_streams): New function.
3908 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3909 and handles errors appropriately.
3910 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3913 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3914 The symptom is a diagnostic "GLib-WARNING **: In call to
3915 g_spawn_sync(), exit status of a child process was requested but
3916 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3917 waitpid(), so exit status can't be returned." The diagnostic
3918 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3919 The real bug is a race condition between Emacs and glib: Emacs
3920 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3921 so that glib can't find it. Work around the bug by invoking
3922 waitpid only on subprocesses that Emacs itself creates.
3923 * process.c (create_process, record_child_status_change):
3924 Don't use special value -1 in pid field, as the caller now must
3925 know the pid rather than having the callee infer it.
3926 The inference was sometimes incorrect anyway, due to another race.
3927 (create_process): Set new 'alive' member if child is created.
3928 (process_status_retrieved): New function.
3929 (record_child_status_change): Use it.
3930 Accept negative 1st argument, which means to wait for the
3931 processes that Emacs already knows about. Move special-case code
3932 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3933 processes that have already been waited for, by testing and
3934 clearing new 'alive' member.
3935 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3936 now does this internally.
3937 (handle_child_signal): Let record_child_status_change do all
3938 the work, since we do not want to reap all exited child processes,
3939 only the child processes that Emacs itself created.
3940 * process.h (Lisp_Process): New boolean member 'alive'.
3942 Omit duplicate definitions no longer needed with gcc -g3.
3943 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3944 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3945 Define only as macros. There's no longer any need to also define
3946 these symbols as enums or as constants, since we now assume
3947 gcc -g3 when debugging.
3949 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3951 * lisp.mk: Adjust comments to the fact that term/internal is now
3952 loaded from loadup.el.
3954 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3955 (msdos_fatal_signal): New function.
3956 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3959 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3960 for GCC versions before 4.
3961 (emacs_raise): Define to call msdos_fatal_signal.
3963 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3964 iterator when starting in the middle of a display or overlay
3967 2012-11-03 Chong Yidong <cyd@gnu.org>
3969 * process.c (wait_reading_process_output): Clean up the last
3972 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3974 * process.c (wait_reading_process_output): Avoid a race condition
3975 with SIGIO delivery (Bug#11536).
3977 2012-11-03 Chong Yidong <cyd@gnu.org>
3979 * buffer.c (cursor_type): Untabify docstring.
3981 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3983 * frame.h (struct frame): Drop can_have_scroll_bars member
3984 which is meaningless for a long time. Adjust comments.
3985 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3986 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3988 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3990 * window.c (decode_next_window_args): Update window arg after
3991 calling decode_live_window and so fix crash reported at
3992 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3993 by Juanma Barranquero <lekktu@gmail.com>.
3994 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3995 * font.c (Ffont_at): Likewise.
3997 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3999 * widget.c (resize_cb): New function.
4000 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4001 (EmacsFrameResize): Check if all is up to date before changing frame
4004 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4006 Implement backtrace output for fatal errors on MS-Windows.
4007 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4008 (BACKTRACE_LIMIT_MAX): New macro.
4009 (w32_backtrace): New function.
4010 (emacs_abort): Use w32_backtrace when the user chooses not to
4011 attach a debugger. Update the text of the abort dialog.
4013 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4015 Window-related stuff cleanup here and there.
4016 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4017 Use decode_any_window.
4018 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4019 * xdisp.c (Fformat_mode_line): Likewise.
4020 * font.c (Ffont_at): Use decode_live_window.
4021 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4022 * window.c (decode_next_window_args): Likewise.
4023 (decode_any_window): Remove static.
4024 * window.h (decode_any_window): Add prototype.
4025 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4026 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4029 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4031 Remove pad from struct input_event.
4032 * termhooks.h (struct input_event): Remove padding field.
4034 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4035 member is never cons for a long time. Adjust comment.
4036 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4037 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4038 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4039 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4041 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4043 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4045 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4047 Fix crash when using Emacs as commit editor for git (Bug#12697).
4048 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4049 and it is configured in conf_post.h.
4050 (Fcall_process): Don't invoke both setsid and setpgid; the former
4051 is enough, if it exists.
4052 * callproc.c (Fcall_process, child_setup):
4053 * process.c (create_process): Use setpgid.
4054 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4056 * dispnew.c (init_display): Initialize the foreground group
4057 if we are running a tty display.
4058 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4059 * lisp.h (init_foreground_group): New decl.
4060 * sysdep.c (inherited_pgroup): New static var.
4061 (init_foreground_group, tcsetpgrp_without_stopping)
4062 (narrow_foreground_group, widen_foreground_group): New functions.
4063 (init_sys_modes): Narrow foreground group.
4064 (reset_sys_modes): Widen foreground group.
4066 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4068 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4070 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4072 * minibuf.c (read_minibuf): Restore current buffer since
4073 choose_minibuf_frame calling Fset_frame_selected_window may
4074 change it (Bug#12766).
4076 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4078 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4080 2012-10-30 Kenichi Handa <handa@gnu.org>
4082 * font.c (Ffont_at): If WINDOW is specified and it is not
4083 displaying the current buffer, signal an error.
4085 2012-10-29 Daniel Colascione <dancol@dancol.org>
4087 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4088 In preparation for fixing bug#12739, move these functions from
4091 * coding.h, coding.c: ... to here, and compile them only when
4092 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4093 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4095 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4097 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4098 (timer_loop, getitimer, setitimer): Use it instead of
4099 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4101 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4104 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4106 * nsterm.m (NO_APPDEFINED_DATA): New define.
4107 (last_appdefined_event_data): New variable
4108 (last_appdefined_event): Remove.
4109 (ns_select): Initialize t from last_appdefined_event_data instead
4110 of [last_appdefined_event data1].
4111 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4112 remove last_appdefined_event (Bug#12698).
4114 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4116 * frame.c (x_set_font): Catch internal error.
4118 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4120 Avoid overflow in w32 implementation of interval timers.
4121 When possible, for ITIMER_PROF count only times the main thread
4123 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4124 'volatile ULONGLONG' types. All the other data which was
4125 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4126 (GetThreadTimes_Proc): New typedef.
4127 (w32_get_timer_time): New function, returns a suitable time value
4129 (timer_loop): Enter critical section when accessing ULONGLONG
4130 values of the itimer_data struct, as these accesses are no longer
4131 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4132 Remove unused variable.
4133 (init_timers): Initialize s_pfn_Get_Thread_Times.
4134 (start_timer_thread): Don't assign itimer->caller_thread here.
4135 (getitimer): Assign itimer->caller_thread here.
4136 (setitimer): Always call getitimer to get the value of ticks_now.
4137 (sys_spawnve): Avoid compiler warning about format mismatch.
4139 2012-10-26 Eli Zaretskii <eliz@gnu.org>
4141 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4142 mouse movement events if the menu bar is active. This avoids
4143 producing a busy "hour-glass" cursor by Windows if the mouse
4144 pointer is positioned over a tooltip shown for some menu item.
4146 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4148 Don't assume process IDs fit in int.
4149 * emacs.c (shut_down_emacs) [!DOS_NT]:
4150 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4151 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:

4633 * unexw32.c, unexcw.c: Include w32common.h.
4635 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4636 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4637 to call syms_of_w32select.
4639 * cygw32.h: Remove obsolete EXFUN declarations.
4641 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4643 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4644 of w32inevt.o from SOME_MACHINE_OBJECTS.
4646 2012-10-08 Daniel Colascione <dancol@dancol.org>
4648 * image.c: Permanent fix for JPEG compilation issue --- limit
4649 jpeglib `boolean' redefinition to Cygwin builds.
4651 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4653 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4655 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4658 2012-10-08 Daniel Colascione <dancol@dancol.org>
4660 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4661 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4662 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4663 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4664 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4665 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4666 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4667 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4668 now a supported configuration.
4670 * Makefile.in: consolidate image variables into LIBIMAGE; add
4671 W32_OBJ and W32_LIBS. Compile new files.
4674 (_DebPrint) declare tracing facility for W32 debugging. We need
4675 to unify tracing later.
4677 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4678 unconditional use of W32 Unicode functions. Cygwin runs only on
4679 100% Unicode operating systems.
4681 * cygw32.c: New file. Define Cygwin-specific facilities.
4682 (Fcygwin_convert_path_to_windows)
4683 (Fcygwin_convert_path_from_windows): New user functions for
4684 accessing Cygwin path-munging routines.
4686 * cygw32.h: New file.
4687 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4688 UTF-16LE strings temporarily inside non-Lisp-visible string
4691 (w32_strerror): Just what it says on the tin.
4693 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4694 also run for Cygwin; both systems have the same problem with using
4695 GUI facilities in a forked child. Also call syms_of_cygw32,
4696 syms_of_w32select in correct places.
4698 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4699 needs fork-then-exec for daemon launching.
4701 * font.h: Include frame.h.
4703 * image.c: Use the image library cache machinery only when we're
4704 compiling for native WINDOWSNT; Cygwin can use shared libraries
4705 like any other Unixlike system.
4707 * keyboard.c: Clarify a comment regarding the input loop.
4709 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4710 functions directly instead of trying to detect at runtime that our
4711 host operating system supports them. We make this change for two
4712 reasons: Cygwin lacks support for the multibyte character
4713 conversion functions used by the legacy menu code, and Cygwin
4714 never needs to rely on non-Unicode APIs.
4716 * unexw32.c (hinst): Declare extern.
4718 * w32.c: Change header order;
4719 (w32_strerror): Move to w32fns.c because we need it for
4720 non-WINDOWSNT builds.
4722 * w32.h: Add #error macro to make sure we don't include w32.h for
4723 Cygwin builds. Remove w32select declarations.
4725 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4726 w32fns.c. w32console.c is WINDOWSNT-only.
4728 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4729 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4731 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4732 (w32_major_version, w32_minor_version, w32_build_number)
4733 (os_subtype, sound_type): Define here
4734 (w32_defined_color): Make color parameter const for consistency
4735 with other _defined_color functions.
4736 (w32_createwindow): Unconditionally call w32_init_class instead of
4737 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4738 through the code is complex and unnecessary because class
4739 registration is practically free.
4740 (w32_name_of_message): New EMACSDEBUG-only function.
4741 (Fset_message_beep): Move here
4742 (Fx_open_connection): Require that the display name for Windows be
4743 "w32" for consistency, emacsclient disambiguation, and maybe, one
4744 day, multi-window-system support.
4745 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4746 Cygwin files for W32 GUI facilities, since these clearly don't
4747 expect Cygwin names.
4748 (_DebPrint): Define.
4749 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4750 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4751 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4752 (w32_last_error): Remove.
4754 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4756 * w32heap.c (syspage_mask): Declare here.
4757 (cache_system_info): Remove.
4759 * w32inevt.c (faked_key): Define globally, not statically.
4760 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4761 (w32_console_toggle_lock_key): Move to w32fns.c.
4763 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4765 * w32proc.c (_DebPrint): Move to w32fns.c.
4766 * w32select.c: Include string.h, stdio.h for Cygwin.
4767 * w32select.h: New File.
4769 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4771 (w32_message_fd): New variable. Under Cygwin, holds the file
4772 descriptor the system used to tell us about pending thread
4775 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4776 that prevented compilation under non-WINDOWSNT systems.
4778 (w32_initialize): Open /dev/windows and assign it to
4779 w32_message_fd. Provide w32 feature.
4781 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4782 (WM_EMACS_INPUT_READY): add.
4783 (prepend_msg, w32_message_fd): Declare globally.
4786 (keyboard_handle): Use only when WINDOWSNT.
4787 (notify_msg_ready): New function. Posts a message to the main
4788 thread's message queue under CYGWIN, which wakes up the main
4789 thread from select(2) by making the /dev/windows file descriptor
4790 ready. Under WINDOWSNT, it sets an event the same way the old
4793 (post, prepend_msg): Actually call notify_msg_ready instead of
4794 setting the input event directly.
4796 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4798 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4799 but it still has blocs in it, don't return it to the system,
4800 instead of aborting. (Bug#12402)
4802 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4804 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4806 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4807 MAC_OS_X_VERSION_10_6.
4808 (syms_of_nsterm): Remove comment about Panther and above for
4810 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4811 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4812 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4814 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4815 MAC_OS_X_VERSION_10_4.
4817 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4818 MAC_OS_X_VERSION_10_2.
4820 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4822 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4823 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4825 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4826 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4827 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4828 Remove ns_in_resize check.
4829 (ns_clear_frame_area): Remove resize handle code.
4831 * nsfns.m (ns_in_resize): Remove.
4832 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4833 Remove ns_in_resize check.
4835 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4837 Improve sys_siglist detection.
4838 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4839 defined as a macro, as is done in Solaris.
4840 (sys_siglist_entries): New macro.
4841 (save_strsignal): Use it.
4842 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4843 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4845 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4847 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4848 fullscreen/Fullscreen.
4850 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4851 tobar_height is new.
4853 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4854 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4855 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4856 (windowDidResize:): Check for correct window if old style fullscreen.
4857 Capitalize word in comment. Remove incorrect comment.
4858 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4859 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4860 error in drawing background.
4861 (toggleFullScreen:): Remove comment. Rearrange calls.
4862 Set toolbar values to zero, save old height in tobar_height.
4863 Restore tool bar height when leaving fullscreen.
4864 (canBecomeMainWindow): New function.
4866 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4868 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4870 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4872 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4874 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4875 that time stamps of directories could also be changed.
4876 Don't request the too broad GENERIC_WRITE, only the more restrictive
4877 FILE_WRITE_ATTRIBUTES access rights.
4879 * fileio.c (Fset_file_times): Special-case ignoring errors for
4880 directories only on MSDOS, not on MS-Windows.
4882 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4884 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4886 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4888 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4889 see whether CreateFile failed.
4891 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4893 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4894 to avoid similar races.
4895 * keyboard.c (pending_signals): Now bool, not int.
4897 Port timers to OpenBSD, plus check for timer failures.
4898 OpenBSD problem reported by Han Boetes.
4899 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4901 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4902 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4903 like OpenBSD, which has timer_settime but does not declare it.
4904 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4905 whether to use itimerspec-related primitives. All uses of
4906 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4908 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4910 * profiler.c (handle_profiler_signal): Fix a malloc race
4911 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4913 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4915 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4917 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4919 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4920 consistent with the change in return value of 'safe_strsignal'.
4922 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4924 Prefer plain 'static' to 'static inline' (Bug#12541).
4925 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4926 (bidi_set_sor_type, bidi_push_embedding_level)
4927 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4928 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
4929 (bidi_cache_search, bidi_cache_ensure_space)
4930 (bidi_cache_iterator_state, bidi_cache_find)
4931 (bidi_peek_at_next_level, bidi_set_paragraph_end)
4932 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4933 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4934 Now 'static', not 'static inline'.
4936 Count overruns when profiling; change units to ns.
4937 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4938 Give extra weight to samples after overruns, to attempt to count
4939 the time more accurately.
4940 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4941 the underlying primitives nominally do ns.
4942 (Fprofiler_cpu_start): Document the change. Mention that
4943 the sampling intervals are only approximate.
4945 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4947 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4949 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4950 case for the special 0 coding-system.
4952 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4953 (Fmake_overlay): Remove redundant tests.
4954 (fix_start_end_in_overlays): Remove redundant recentering.
4956 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4958 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4959 Update dependencies.
4961 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4963 Fix a malloc race condition involving strsignal.
4964 A signal can arrive in the middle of a malloc, and Emacs's signal
4965 handler can invoke strsignal, which can invoke malloc, which is
4966 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4967 Fix it by altering the signal handler so that it does not invoke
4969 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4970 * process.c (status_message): Use const pointer, in case strsignal
4971 is #defined to safe_strsignal.
4972 * sysdep.c (sys_siglist, init_signals): Always define and
4973 initialize a substitute sys_siglist if the system does not define
4974 one, even if HAVE_STRSIGNAL.
4975 (safe_strsignal): Rename from strsignal. Always define,
4976 using sys_siglist. Return a const pointer.
4977 * syssignal.h (safe_strsignal): New decl.
4978 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4980 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4982 * w32proc.c (timer_loop): Fix code that waits for timer
4983 expiration, to avoid high CPU usage.
4985 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4987 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4988 (sweep_weak_table): Remove redundant prototypes.
4990 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4992 * emacs.c: Move the inclusion of TERM_HEADER after including
4993 windows.h on WINDOWSNT. This avoids compilation problems with
4996 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4998 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4999 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5000 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5001 as the previous version used 'void *'.
5003 * ralloc.c (ROUNDUP): Fix last change.
5004 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5007 * w32proc.c <disable_itimers>: New static flag.
5008 (init_timers): Initialize it to zero, after creating the critical
5009 sections used by the timer threads.
5010 (term_timers): Set to 1 before deleting the critical sections.
5011 (getitimer, setitimer): If disable_itimers is non-zero, return an
5012 error indication without doing anything. Reported by Fabrice
5013 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5014 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5016 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5019 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5020 term_ntproc after all the other bookkeeping, to get timers working
5021 as long as possible.
5023 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5025 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5026 Suggested by Juri Linkov in
5027 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5029 Prefer plain 'static' to 'static inline' (Bug#12541).
5030 With static functions, modern compilers inline pretty well by
5031 themselves; advice from programmers often hurts as much as it helps.
5032 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5033 this change shrinks the text size of the Emacs executable by 1.1%
5034 without affecting CPU significantly in my benchmark.

5333 for consistency with other handlers.
5334 (setup_cpu_timer): New function, with much of what used to be in

5336 Prefer timer_settime if available, and prefer
5337 thread cputime clocks, then process cputime clocks, then
5338 monotonic clocks, to the old realtime clock. Use make_timeval
5339 to round more-correctly when falling back to setitimer.
5340 (Fprofiler_cpu_start): Use it.
5341 (Fprofiler_cpu_stop): Prefer timer_settime if available.

5408 Since this stuff is now private to charset.c, there's no need for
5409 a public macro and no need to inline by hand.

5442 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>

5483 (sys_kill): Improve commentary.
5485 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5486 consistency with a signature of a signal handler. All callers
5488 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5489 install term_ntproc as a signal handler for SIGABRT, as that
5490 should be done by the dumped Emacs.

5551 Use bool for booleans.
5553 2012-09-24 Chong Yidong <cyd@gnu.org>
5555 * chartab.c (Fset_char_table_default): Obsolete function removed.
5557 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5559 Move pid_t related decls out of lisp.h.
5560 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5561 (interruptible_wait_for_termination):
5562 Move these decls from lisp.h to syswait.h, since they use pid_t.
5563 Needed on FreeBSD; see Herbert J. Skuhra in
5564 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5565 * callproc.c: Include syswait.h.

5611 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5613 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5614 fatal_error_backtrace.
5616 * w32proc.c (sys_kill): Undo last change: don't do anything when
5617 invoked to deliver SIGABRT to our own process. This is now
5618 handled by emacs_raise.
5620 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5622 * w32term.c (w32_read_socket): Remove leftover reference to
5623 interrupt_input_pending.
5625 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5627 Do not use SA_NODEFER.
5628 Problem reported by Dani Moncayo in
5629 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5631 * sysdep.c (emacs_abort): Do not reset signal handler.
5632 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5633 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5634 wanted even on POSIXish hosts, and it doesn't work on Windows.
5636 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5638 * xterm.c (x_term_init): Call fixup_locale before and after calling
5639 gtk_init (Bug#12392).
5641 2012-09-23 Chong Yidong <cyd@gnu.org>
5643 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5644 Vdynamic_library_alist.
5646 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5647 (Fgnutls_available_p): Caller changed.
5649 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5650 (Flibxml_parse_xml_region): Likewise.
5652 * dispextern.h (struct image_type): Remove arg from init function.
5654 * image.c (Finit_image_library, lookup_image_type)
5655 (define_image_type): Remove now-unneeded second arg.
5656 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5657 (init_tiff_functions, init_gif_functions, init_svg_functions):
5658 Arglist and w32_delayed_load calling convention changed.
5659 (gs_type): Remove init_gs_functions; there is no such function.
5660 (valid_image_p, make_image): Fix caller to lookup_image_type.
5662 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5664 Simplify and avoid signal-handling races (Bug#12471).
5666 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5667 Avoid recursive loop if there's a fatal error in the function itself.
5668 * atimer.c (pending_atimers):
5669 * blockinput.h: Don't include "atimer.h"; no longer needed.
5670 (interrupt_input_pending): Remove. All uses removed.
5671 pending_signals now counts both atimers and ordinary interrupts.
5672 This is less racy than having three separate pending-signal flags.
5673 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5675 Rename from their upper-case counterparts BLOCK_INPUT,
5676 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5677 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5678 This makes it easier to access volatile variables more accurately.
5679 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5680 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5681 that's more reliable if the code is buggy and sets
5682 interrupt_input_blocked to a negative value. All uses changed.
5683 * atimer.c (deliver_alarm_signal):
5684 Remove. No need to deliver this to the parent; any thread can
5685 handle this signal now. All uses replaced by underlying handler.
5686 * atimer.c (turn_on_atimers):
5687 * dispnew.c (handle_window_change_signal):
5688 * emacs.c (handle_danger_signal):
5689 * keyboard.c (kbd_buffer_get_event):
5690 Don't reestablish signal handler; not needed with sigaction.
5691 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5693 Rework to avoid unnecessary accesses to volatile variables.
5694 (UNBLOCK_INPUT_TO): Now a function.
5695 (totally_unblock_input, unblock_input): New decls.
5696 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5697 (init_data): Remove. Necessary stuff now done in init_signal.
5698 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5699 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5700 (fatal_error_code): Remove; no longer needed.
5701 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5702 it doesn't always backtrace. All uses changed. No need to reset
5703 signal to default, since sigaction and/or die does that for us now.
5704 Use emacs_raise (FOO), not kill (getpid (), FOO).
5705 (main): Check more-accurately whether we're dumping.
5706 Move fatal-error setup to sysdep.c
5707 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5708 * gtkutil.c (xg_get_file_name, xg_get_font):
5709 Remove no-longer-needed signal-mask manipulation.
5710 * keyboard.c, process.c (POLL_FOR_INPUT):
5711 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5712 * keyboard.c (read_avail_input): Remove.
5713 All uses replaced by gobble_input.
5714 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5715 (kbd_buffer_store_event_hold, gobble_input):
5716 (record_asynch_buffer_change) [USABLE_SIGIO]:
5717 (store_user_signal_events):
5718 No need to mess with signal mask.
5719 (gobble_input): If blocking input and there are terminals, simply
5720 set pending_signals to 1 and return. All hooks changed to not
5721 worry about whether input is blocked.
5722 (process_pending_signals): Clear pending_signals before processing
5723 them, in case a signal comes in while we're processing.
5724 By convention callers now test pending_signals before calling us.
5725 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5726 New functions, to support changes to blockinput.h.
5727 (handle_input_available_signal): Now extern.
5728 (reinvoke_input_signal): Remove. All uses replaced by
5730 (quit_count): Now volatile, since a signal handler uses it.
5731 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5732 All callers changed. Block SIGINT only if not already blocked.
5733 Clear sigmask reliably, even if Fsignal returns, which it can.
5734 Omit unnecessary accesses to volatile var.
5735 (quit_throw_to_read_char): No need to restore sigmask.
5736 * keyboard.c (gobble_input, handle_user_signal):
5737 * process.c (wait_reading_process_output):
5738 Call signal-handling code rather than killing ourselves.
5739 * lisp.h: Include <float.h>, for...
5740 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5741 (pending_signals): Now volatile.
5742 (syms_of_data): Now const if IEEE floating point.
5743 (handle_input_available_signal) [USABLE_SIGIO]:
5744 (terminate_due_to_signal, record_child_status_change): New decls.
5745 * process.c (create_process): Avoid disaster if memory is exhausted
5746 while we're processing a vfork, by tightening the critical section
5748 (send_process_frame, process_sent_to, handle_pipe_signal)
5749 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5751 (send_process): No need for setjmp/longjmp any more, since the
5752 SIGPIPE stuff is now gone. Instead, report an error if errno
5754 (record_child_status_change): Now extern. PID and W are now args.
5755 Return void, not bool. All callers changed.
5756 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5757 Remove. All uses removed. This bug should be fixed now in a
5759 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5760 and record the child status change directly. This avoids the
5761 need to futz with the signal mask.
5762 (process_fatal_action): Move here from emacs.c.
5763 (emacs_sigaction_flags): New function, containing
5764 much of what used to be in emacs_sigaction_init.
5765 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5766 caught by emacs, to make races less likely.
5767 (deliver_process_signal): Rename from handle_on_main_thread.
5769 (BACKTRACE_LIMIT_MAX): Now at top level.
5770 (thread_backtrace_buffer, threadback_backtrace_pointers):
5772 (deliver_thread_signal, deliver_fatal_thread_signal):
5773 New functions, for more-accurate delivery of thread-specific signals.
5774 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5775 (deliver_arith_signal): Handle in this thread, not
5776 in the main thread, since it's triggered by this thread.
5777 (maybe_fatal_sig): New function.
5778 (init_signals): New arg DUMPING so that we can be more accurate
5779 about whether we're dumping. Caller changed.
5780 Treat thread-specific signals differently from process-general signals.
5781 Block all signals while handling fatal error; that's safer.
5782 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5784 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5785 Ignore SIGPIPE unless batch.
5786 (emacs_backtrace): Output backtrace for the appropriate thread,
5787 which is not necessarily the main thread.
5788 * syssignal.h: Include <stdbool.h>.
5789 (emacs_raise): New macro.
5790 * xterm.c (x_connection_signal): Remove; no longer needed
5791 now that we use sigaction.
5792 (x_connection_closed): No need to mess with sigmask now.
5793 (x_initialize): No need to reset SIGPIPE handler here, since
5794 init_signals does this for us now.
5796 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5798 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5799 background rect may be larger (Bug#12245).
5801 2012-09-23 Chong Yidong <cyd@gnu.org>
5803 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5805 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5807 * .gdbinit: Just stop at fatal_error_backtrace.
5808 See Stefan Monnier's request in
5809 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5810 Remove no-longer-used query of system type.
5812 2012-09-22 Chong Yidong <cyd@gnu.org>
5814 * search.c (Freplace_match): Doc fix (Bug#12325).
5816 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5818 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5819 (Fline_end_position): Doc fix.
5821 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5823 2012-09-22 Chong Yidong <cyd@gnu.org>
5825 * dispextern.h (struct image_type): Add new slot, storing a type
5826 initialization function.
5828 * image.c (define_image_type): Call the image initializer function
5829 if it is defined. Arguments and return value changed.
5830 (valid_image_p, make_image): Callers changed.
5831 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5832 (gif_type, imagemagick_type, svg_type, gs_type):
5833 Add initialization functions.
5834 (Finit_image_library): Call lookup_image_type.
5835 (CHECK_LIB_AVAILABLE): Macro deleted.
5836 (lookup_image_type): Call define_image_type here, rather than via
5837 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5838 (syms_of_image): Move define_image_type calls for xbm_type and
5839 pbm_type to lookup_image_type.
5841 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5843 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5844 'idle_timers' from here ...
5845 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5846 lists, to avoid infloops when the timer does something stupid,
5847 like reinvoke itself with the same or smaller time-out.
5850 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5852 * window.c (Fsplit_window_internal): Handle only Qt value of
5853 Vwindow_combination_limit separately.
5854 (Qtemp_buffer_resize): New symbol.
5855 (Vwindow_combination_limit): New default value.
5858 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5860 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5861 the new overlay string. (Bug#10159)
5863 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5865 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5866 or that fprintf is async-signal-safe. POSIX doesn't require
5869 2012-09-22 Chong Yidong <cyd@gnu.org>
5871 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5874 2012-09-22 Kenichi Handa <handa@gnu.org>
5876 * composite.c (composition_reseat_it): Handle the case that a
5877 grapheme cluster is not covered by a single font (Bug#12352).
5879 2012-09-21 Chong Yidong <cyd@gnu.org>
5881 * image.c (define_image_type): Avoid adding duplicate types to
5882 image_types (Bug#12463). Suggested by Jörg Walter.
5884 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5886 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5887 (print_load_command_name): Add case LC_DATA_IN_CODE.
5888 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.

5892 * eval.c (Frun_hook_with_args_until_success)
5893 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5895 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5897 * fileio.c (Ffile_selinux_context): Only call freecon when
5898 lgetfilecon succeeded.
5899 (Fset_file_selinux_context): Likewise. (Bug#12444)
5901 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5903 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5904 reordering, locate the cursor by calling set_cursor_from_row; if
5905 that fails, clear the desired glyph matrix before returning a
5906 failure indication to the caller. Fixes leaving garbled display
5907 when fast scrolling with a down-key. (Bug#12403)
5908 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5909 scrolling through multibyte text.
5911 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5913 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5914 calling mark_vectorlike since that's the one that marks the window.
5915 (mark_discard_killed_buffers): Mark the final cdr.
5916 * window.h (struct window): Move prev/next_buffers to the
5917 non-standard fields.
5918 * window.c (make_window): Initialize prev/next_buffers manually.
5920 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5922 Omit unused arg EXPECTED from socket hooks.
5923 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5924 * nsterm.m (ns_term_init):
5925 * termhooks.h (struct terminal.read_socket_hook):

5927 * w32term.c (w32_read_socket):
5928 * xterm.c (XTread_socket):
5929 Omit unused arg EXPECTED. All callers changed.
5930 (store_user_signal_events): Return void, not int, since callers no
5931 longer care about the return value. All uses changed.
5933 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5935 * w32gui.h (XParseGeometry): Do not declare.
5937 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5939 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5940 Ignore 'expected'. See Eli Zaretskii in
5941 <http://bugs.gnu.org/12471#8> (last line).
5943 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5944 (XParseGeometry): Now static. Substitute extremal values for
5945 values that are out of range.
5947 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5949 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5951 * nsfns.m (XParseGeometry): Remove.
5952 (Fx_create_frame): Call x_set_offset to correctly interpret
5953 top_pos in geometry.
5955 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5956 (Fx_parse_geometry): If there is a space in string, call
5957 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5959 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5961 * search.c (scan_buffer): Use character positions in calls to
5962 region_cache_forward and region_cache_backward, not byte
5963 positions. (Bug#12196)
5965 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5966 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5968 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5969 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5970 emacs_blocked_malloc, now deleted.
5972 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5974 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5975 The workaround was for improving performance on Solaris 2.4, but
5976 is getting in the way now. Emacs will still work if someone is
5977 still running Solaris 2.4 in a museum somewhere; Sun dropped
5978 support for Solaris 2.4 in 2003.
5979 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5980 * process.c (create_process) [HAVE_WORKING_VFORK]:
5981 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5982 since Emacs no longer uses vfork on that platform.
5984 2012-09-17 Glenn Morris <rgm@gnu.org>
5986 * emacs.c: Use COPYRIGHT.
5988 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5990 Remove configure's --without-sync-input option (Bug#12450).
5991 When auditing signal-handling in preparation for cleaning it up,
5992 I found that SYNC_INPUT has race conditions and would be a real
5993 pain to fix. Since it's an undocumented and deprecated
5994 configure-time option, now seems like a good time to remove it.
5995 Also see <http://bugs.gnu.org/11080#16>.
5996 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5997 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5998 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5999 (malloc_hysteresis):
6000 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6001 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6002 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6003 (dont_register_blocks, bytes_used_when_reconsidered)
6004 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6005 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6006 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6007 Remove. All uses removed.
6008 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6009 implementation, one that depends on whether the new macro
6010 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6012 * atimer.c (run_timers, handle_alarm_signal):
6013 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6014 (handle_async_input, process_pending_signals)
6015 (handle_input_available_signal, init_keyboard):
6016 * nsterm.m (ns_read_socket):
6017 * process.c (wait_reading_process_output):
6018 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6019 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6021 * xterm.c (XTread_socket):
6023 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6024 * eval.c (handling_signal): Remove. All uses removed.
6025 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6026 All uses replaced with the SYNC_INPUT version.
6027 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6029 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6032 * font.c (Ffont_shape_gstring): Remove unused local.
6034 2012-09-16 Glenn Morris <rgm@gnu.org>
6036 * Makefile.in (clean): No longer run nextstep's clean.
6038 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6040 (ns-app): Move here from ns.mk, and simplify.
6041 (clean): Simplify nextstep entry.
6042 * ns.mk: Remove file.
6044 2012-09-17 Kenichi Handa <handa@gnu.org>
6046 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6047 not covert the last few charactes.
6049 2012-09-16 Kenichi Handa <handa@gnu.org>
6051 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6052 here, but just check the validity of glyphs in the glyph-string.
6054 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6056 * window.c (Fwindow_parameter, Fset_window_parameter):
6057 Accept any window as argument (Bug#12452).
6059 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6061 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6062 to ns_term_init to avoid memory leak.
6064 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6065 explicit retain/release.
6066 (ns_term_init): Only allow one display. Initialize outerpool and
6069 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6071 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6072 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6073 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6074 the Microsoft problem in a different way, by altering ../nt/config.nt.
6076 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6091 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6092 by lisp.h. This completes removal of setjmp.h inclusion
6093 erroneously announced in the previous commit. (Bug#12446)
6095 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6098 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6099 not defined as a macro. The latter happens on MS-Windows.
6102 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6104 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6105 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6106 Some instances of '#include <setjmp.h>' removed, if the
6107 only reason for the instance was because "lisp.h" was included.
6108 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6109 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6110 and _longjmp with the new symbols. Emacs already uses _setjmp if
6111 available, so this change affects only POSIXish hosts that have
6112 sigsetjmp but not _setjmp, such as some versions of Solaris and
6113 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6114 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6115 (png_load_body) [HAVE_PNG]:
6116 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6117 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6118 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6119 since PNG requires jmp_buf. This is the only exception to the
6120 general rule that we now use sys_setjmp and sys_longjmp.
6121 This exception is OK since this code does not change the signal
6122 mask or longjmp out of a signal handler.
6124 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6126 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6127 Include "syssignal.h", for 'main_thread'.
6129 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6131 Avoid out-of-range marker position (Bug#12426).
6132 * insdel.c (replace_range, replace_range_2):
6133 Adjust markers before overlays, as suggested by comments.
6134 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6135 Remove redundant check before calling offset_intervals.
6137 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6139 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6140 current buffer (Bug#12387).
6142 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6144 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6146 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6148 Use a more backwards-compatible timer format (Bug#12430).
6149 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6150 vector element, not from the 4th, since PSECS is now at the end.
6151 (Fcurrent_idle_time): Doc fix.
6153 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6155 Function to mark objects and remove killed buffers at once.
6156 * alloc.c (discard_killed_buffers): Rename to ...
6157 (mark_discard_killed buffers) ... new name. Add marking
6158 of remaining objects. Fix comment. Adjust users.
6159 (mark_object): Do not touch frame buffer lists here.
6160 * frame.c (delete_frame): Reset frame buffer lists here.
6162 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6164 Better workaround for GNOME bug when --enable-gcc-warnings.
6165 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6166 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6167 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6169 Simplify SIGIO usage (Bug#12408).
6170 The code that dealt with SIGIO was crufty and confusing, e.g., it
6171 played tricks like "#undef SIGIO" but these tricks were not used
6172 consistently. Simplify mostly by not #undeffing standard symbols,
6173 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6174 or not as we please) rather than "defined SIGIO" (standard symbol
6175 that we probably shouldn't #undef).
6176 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6177 Modules that need it can include it.
6178 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6179 * dispextern.h (ignore_sigio): New decl.
6180 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6181 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6182 * emacs.c (shut_down_emacs):
6183 * keyboard.c (kbd_buffer_store_event_hold):
6184 Use ignore_sigio rather than invoking 'signal' directly.
6185 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6187 (FIONREAD, SIGIO): Do not #undef.
6188 (tty_read_avail_input): Use #error rather than a syntax error.
6189 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6190 for I_PIPE, used by SETUP_SLAVE_PTY.
6191 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6192 * sysdep.c (croak): Remove; no longer needed. This bit of
6193 temporary code, with Fred N. Fish's comment that it's temporary,
6194 has been in Emacs since at least 1992!
6195 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6196 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6197 * syssignal.h (croak): Remove decl.
6198 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6199 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6200 now that we're termios-only.
6201 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6202 * term.c (dissociate_if_controlling_tty): Use #error rather than
6205 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6206 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6207 to work around GNOME bug 683906.
6208 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6209 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6210 This works around GCC bug 54561.
6212 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6214 More fixes for 'volatile' and setjmp/longjmp.
6215 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6216 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6217 (png_load_body) [HAVE_PNG]:
6218 (jpeg_load_body) [HAVE_JPEG]:
6219 New function, with most of the old parent function's body.
6220 (png_load) [HAVE_PNG]:
6221 (jpeg_load) [HAVE_JPEG]:
6222 Invoke the new function, to avoid longjmp munging our locals.
6223 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6224 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6225 longjmp is passed 2, as the C standard doesn't guarantee this.
6226 Instead, store the failure code into mgr->failure_code.
6228 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6230 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6231 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6232 (syms_of_keyboard): Remove support for unread-command-char.
6234 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6236 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6237 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6238 violation. (Bug#12426)
6240 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6242 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6244 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6246 * eval.c: Add `inhibit-debugger'.
6247 (Qinhibit_debugger): New symbol.
6248 (call_debugger): Bind it instead of Qdebug_on_error.
6249 (maybe_call_debugger): Test Vinhibit_debugger.
6250 (syms_of_eval): Define inhibit-debugger.
6251 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6252 (syms_of_xdisp): Remove inhibit-debug-on-message.
6254 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6256 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6257 If a nonvolatile local variable is written before a _longjmp to
6258 the frame containing the variable, and is read after the _longjmp,
6259 the value read is indeterminate. Some local variables of type
6260 'struct handler' and 'struct catchtag' are used in this way, so
6261 mark each of their slots as volatile if the slot can be set before
6262 _longjmp and read afterwards.
6263 * lisp.h (struct handler): var and chosen_clause are now volatile.
6264 (struct catchtag): val, next, and pdlcount are now volatile.
6266 * bidi.c (bidi_push_it, bidi_pop_it):
6267 * fns.c (copy_hash_table):
6268 * image.c (define_image_type):
6269 * keyboard.c (kbd_buffer_store_event_hold):
6270 * process.c (Fprocess_send_eof):
6271 * xfaces.c (x_create_gc) [HAVE_NS]:
6272 * xgselect.c (xg_select):
6273 Prefer assignment to memcpy when either will do.
6275 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6276 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6277 time an item is removed. No need to mark this function 'inline';
6278 the compiler knows better than we do.
6280 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6282 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6283 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6284 to change_frame_size (Bug#12388).
6285 (windowDidResize:): Pass YES to updateFrameSize.
6287 * nsterm.h: Add delay parameter to updateFrameSize.
6289 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6291 Discard killed buffers from deleted window and frame objects.
6292 This reduces an amount of references to killed buffers and
6293 helps GC to reclaim them faster.
6294 * alloc.c (discard_killed_buffers): New function.
6295 (mark_object): Use it for deleted windows and frames.
6296 (mark_object): If symbol's value is set up for a killed buffer
6297 or deleted frame, restore its global binding.
6298 * data.c (swap_in_global_binding): Add GC notice.
6299 (swap_in_symval_forwarding): Use convenient set_blv_where.
6300 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6301 * window.h: ... to here.
6303 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6305 Convenient macro to check whether the buffer is live.
6306 * buffer.h (BUFFER_LIVE_P): New macro.
6307 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6308 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6310 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6312 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6313 composition cases (Bug#12364).
6315 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6316 overhang of succeeding glyphs overlapping box cursor.
6318 * w32term.c (x_draw_glyph_string): Likewise.
6320 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6322 Simplify, document, and port floating-point (Bug#12381).
6323 The porting part of this patch fixes bugs on non-IEEE platforms
6324 with frexp, ldexp, logb.
6325 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6327 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6328 support, by removing commented-out code and briefly listing the
6329 C89 functions excluded. The commented-out stuff was confusing
6330 maintenance, e.g., we thought we needed cbrt but it was commented out.
6331 (logb): Remove decl; no longer needed.
6332 (isfinite): New macro, if not already supplied.
6333 (isnan): Don't replace any existing macro.
6334 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6335 are present on all C89 platforms.
6336 (Ffrexp): Do not special-case zero, as frexp does the right thing
6338 (Flogb): Do not use logb, as it doesn't have the desired meaning
6339 on hosts that use non-base-2 floating point. Instead, stick with
6340 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6341 frexp, to avoid getting an unspecified result.
6343 * xdisp.c (Qinhibit_debug_on_message): Now static.
6345 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6347 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6348 NSBezierPath (Bug#12131).
6350 2012-09-10 Chong Yidong <cyd@gnu.org>
6352 * fns.c (Fdelq, Fdelete): Doc fix.
6354 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6356 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6357 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6359 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6361 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6362 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6365 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6367 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6368 left fringe if the window has a left margin. This avoids leaving
6369 traces of the cursor because its leftmost pixel is not drawn over.
6371 * dispnew.c (update_window_line): When the left margin area of a
6372 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6373 that screen line. (Bug#12277)
6375 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6377 Assume C89 or later for math functions (Bug#12381).
6378 This simplifies the code, and makes it a bit smaller and faster,
6379 and (most important) makes it easier to clean up signal handling
6380 since we can stop worring about floating-point exceptions in
6381 library code. That was a problem before C89, but the problem
6382 went away many years ago on all practical Emacs targets.
6383 * data.c, image.c, lread.c, print.c:
6384 Don't include <math.h>; no longer needed.
6385 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6386 might be autoconfigured, as that never happens.
6388 * doprnt.c (DBL_MAX_10_EXP):
6389 * print.c (DBL_DIG):
6390 Remove. C89 or later always defines these.
6391 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6392 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6393 (arith_error, domain_error, domain_error2):
6394 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6395 no longer needed -- we simply return what C returns. All uses removed.
6396 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6398 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6399 Remove. All uses expanded, as these macros are no longer used
6400 more than once and are now more trouble than they're worth.
6401 (Ftan): Use tan, not sin / cos.
6402 (Flogb): Assume C89 frexp.
6403 (fmod_float): Assume C89 fmod.
6404 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6405 (init_floatfns): Remove. All uses removed.
6407 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6409 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6410 compositeToPoint for OSX < 10.6 (Bug#12390).
6412 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6414 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6415 This produces more-accurate results.
6417 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6419 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6420 changes (Bug#12088).
6422 2012-09-08 Chong Yidong <cyd@gnu.org>
6424 * syntax.c (Fstring_to_syntax): Doc fix.
6426 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6428 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6429 in the internal border.
6430 (x_set_window_size): Remove static variables and their usage.
6431 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6432 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6433 Remove fringe/internal border adjustment (Bug#11052).
6434 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6435 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6436 (ns_fix_rect_ibw): Remove.
6437 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6438 (ns_dumpglyphs_box_or_relief): Ditto.
6439 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6441 (ns_dumpglyphs_image): Ditto.
6442 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6444 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6445 their usage. Add fringe_extended_p and its use as in other terms.
6446 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6447 scroll bar was removed.
6448 (updateFrameSize): New function.
6449 (windowDidResize): Move code to updateFrameSize and call it.
6451 * nsterm.h (EmacsView): Add updateFrameSize.
6453 2012-09-07 Chong Yidong <cyd@gnu.org>
6455 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6457 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6459 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6461 More signal-handler cleanup (Bug#12327).
6462 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6463 Problem introduced when merging patches. Noted by Eli Zaretskii in
6464 <http://bugs.gnu.org/12327#67>.
6465 * floatfns.c: Comment fix.
6466 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6467 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6468 and anyway the declaration is harmless even if SIGDANGER is not defined.
6469 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6470 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6471 source files not surprisingly expected syssignal.h to define, or
6472 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6473 Include <sys/ioctl.h>, for FIONREAD.
6474 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6475 This eliminates a problem whereby other files mysteriously had
6476 to include "syssignal.h" before including "systty.h" if they
6477 wanted to use "#ifdef SIGIO".
6479 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6481 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6483 * w32.c (sigemptyset): Empty the set.
6484 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6486 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6488 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6490 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6491 (mark_object): Likewise for frame objects.
6493 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6495 * syssignal.h (handle_on_main_thread): Always declare,
6496 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6497 This ports to platforms without HAVE_PTHREAD.
6499 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6501 Signal-handler cleanup (Bug#12327).
6502 Emacs's signal handlers were written in the old 4.2BSD style with
6503 sigblock and sigmask and so forth, and this led to some
6504 inefficiencies and confusion. Rewrite these to use
6505 pthread_sigmask etc. without copying signal sets around. Also,
6506 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6507 'signal', and instead use functions that do not attempt to take
6508 over the system name space. This patch causes Emacs's text
6509 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6510 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6511 Do not include <signal.h> or "syssignal.h", as these
6512 modules do not use signals.
6513 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6514 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6515 Do not include <signal.h>, as "syssignal.h" does that for us now.
6516 * atimer.c (sigmask_atimers): New function.
6517 (block_atimers, unblock_atimers): New functions,
6518 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6520 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6521 no longer needed here.
6522 * emacs.c (main): Inspect existing signal handler with sigaction,
6523 so that there's no need to block and unblock SIGHUP.
6524 * sysdep.c (struct save_signal): New member 'action', replacing
6525 old member 'handler'.
6526 (save_signal_handlers, restore_signal_handlers):
6527 Use sigaction instead of 'signal' to save and restore.
6528 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6529 New function. All users of 'signal' modified to use set_sighandler
6530 if they're writeonly, and to use sys_signal if they're read+write.
6531 (emacs_sigaction_init, forwarded_signal): New functions.
6532 (sys_signal): Remove. All uses replaced by calls to sigaction
6533 and emacs_sigaction_init, or by direct calls to 'signal'.
6534 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6535 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6536 all uses replaced by pthread_sigmask etc. calls.
6537 * syssignal.h: Include <signal.h>.
6538 (emacs_sigaction_init, forwarded_signal): New decls.
6539 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6540 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6541 (sigmask, sys_sigmask): Remove; no longer needed.
6542 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6543 (sigblock, sigunblock, sigfree):
6544 (sigsetmask) [!defined sigsetmask]:
6545 Remove. All uses replaced by pthread_sigmask.
6546 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6547 no longer need to be replaced, and its typical old uses
6548 are now done via emacs_sigaction_init and sigaction.
6549 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6550 (sys_sigdel): Remove; unused.
6551 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6553 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6555 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6556 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6558 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6560 Explicitly mark buffer_defaults and buffer_local_symbols.
6561 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6562 mark_local_symbols here.
6563 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6564 since special buffers aren't marked here any more.
6565 (allocate_buffer): Chain new buffer with all_buffers here...
6566 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6568 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6569 (syms_of_buffer): Remove staticpro of the above.
6570 (init_buffer_once): Set names for buffer_defaults and
6571 buffer_local_symbols.
6573 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6575 Use bool for booleans in font-related modules.
6576 * font.c (font_intern_prop, font_style_to_value)
6577 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6578 (generate_otf_features, font_check_otf_features, font_check_otf)
6579 (font_match_p, font_list_entities, font_at):
6580 * fontset.c (fontset_id_valid_p, reorder_font_vector
6581 (fontset_find_font, Fset_fontset_font)
6582 (face_suitable_for_char_p) [0]:
6583 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6584 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6585 (m17n_flt_initialized, ftfont_shape_by_flt):
6586 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6587 * nsfont.m (nsfont_draw):
6588 * w32font.c (w32font_draw):
6589 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6590 Use bool for booleans.
6591 * font.h: Adjust to above API changes.
6592 (struct font, struct font_driver, struct font_driver_list):
6593 Use bool for booleans.
6594 (struct font): Remove useless member encoding_type.
6596 * fontset.c, xftfont.c: Omit unnecessary static decls.
6598 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6600 * alloc.c (mark_object): Revert window marking code
6601 since it's unsafe for the Fset_window_configuration.
6603 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6605 Fix race conditions with signal handlers and errno (Bug#12327).
6606 Be more systematic about preserving errno whenever a signal
6607 handler returns, even if it's not in the main thread. Do this by
6608 renaming signal handlers to distinguish between signal delivery
6609 and signal handling. All uses changed.
6610 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6611 * data.c (deliver_arith_signal): Rename from arith_error.
6612 * dispnew.c (deliver_window_change_signal): Rename from
6613 window_change_signal.
6614 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6615 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6616 * keyboard.c (deliver_input_available_signal): Rename from
6617 input_available_signal.
6618 (deliver_user_signal): Rename from handle_user_signal.
6619 (deliver_interrupt_signal): Rename from interrupt_signal.
6620 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6621 (deliver_child_signal): Rename from sigchld_handler.
6622 * atimer.c (handle_alarm_signal):
6623 * data.c (handle_arith_signal):
6624 * dispnew.c (handle_window_change_signal):
6625 * emacs.c (handle_fatal_signal, handle_danger_signal):
6626 * keyboard.c (handle_input_available_signal):
6627 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6628 * process.c (handle_pipe_signal, handle_child_signal):
6629 New functions, with the actual signal-handling code taken from the
6630 original respective signal handlers, sans the sporadic attempts to
6631 preserve errno, since that's now done by handle_on_main_thread.
6632 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6633 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6634 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6636 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6637 Move initialization of main_thread to sysdep.c's init_signals.
6638 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6639 our usage, and simplifies the mainline code.
6640 (record_child_status_change): New static function, as a helper
6641 for handle_child_signal, and with most of the old child handler's
6643 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6644 (handle_child_signal): Use the above.
6645 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6646 Moved here from emacs.c.
6647 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6648 code moved here from emacs.c's main function.
6649 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6650 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6651 This lets callers save and restore errno properly.
6653 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6655 Remove redundant or unused things here and there.
6656 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6657 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6658 * editfns.c (Fcompare_buffer_substrings): Likewise.
6659 * frame.h (struct terminal, struct font_driver_list):
6660 Remove redundant declarations.
6661 * window.h (Qleft, Qright): Likewise.
6663 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6665 Do not mark objects from deleted buffers, windows and frames.
6666 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6667 (mark_object): Likewise for windows and frames.
6669 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6671 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6672 buffer_defaults and buffer_local_symbols as valid objects.
6673 Return special value to denote them.
6675 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6677 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6678 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6679 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6680 (file_name_absolute_p, Fsubstitute_in_file_name):
6681 (check_executable, check_writable, Ffile_accessible_directory_p)
6682 (Fset_file_selinux_context, Fdefault_file_modes)
6683 (Finsert_file_contents, choose_write_coding_system)
6684 (Fwrite_region, build_annotations, a_write, e_write)
6686 * filelock.c (boot_time_initialized, get_boot_time)
6687 (get_boot_time_1, lock_file_1, within_one_second):
6688 * floatfns.c (in_float):
6689 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6690 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6691 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6692 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6693 * window.c (compare_window_configurations):
6694 Use bool for booleans.
6695 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6696 (Fdefault_file_modes): Now mode_t, not int, for modes.
6697 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6698 (internal_delete_file): Now returns void, not a (boolean) int,
6699 since nobody was looking at the return value.
6700 * lisp.h, window.h: Adjust to above API changes.
6702 * xdisp.c (set_message): Simplify and reindent last change.
6704 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6706 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6708 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6710 * eval.c (call_debugger): Make the function non-static so that we
6711 can call it from set_message.
6713 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6714 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6716 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6718 Give more-useful info on a fatal error (Bug#12328).
6719 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6720 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6721 of doing the work ourselves.
6722 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6723 do most of the work.
6724 (fatal_error_backtrace): New function, taken from the guts
6725 of the old fatal_error_signal, but with a new option to output
6727 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6728 info about the signal than just its number.
6729 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6730 * sysdep.c: Include <execinfo.h>
6731 (emacs_backtrace): New function, taken partly from the previous
6732 code of the 'die' function.
6733 (emacs_abort): Call fatal_error_backtrace rather than abort.
6735 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6737 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6738 eager (load-time) macro-expansion.
6739 * lisp.mk (lisp): Add macroexp.
6741 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6743 Simplify redefinition of 'abort' (Bug#12316).
6744 Do not try to redefine the 'abort' function. Instead, redo
6745 the code so that it calls 'emacs_abort' rather than 'abort'.
6746 This removes the need for the NO_ABORT configure-time macro
6747 and makes it easier to change the abort code to do a backtrace.
6748 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6749 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6750 Remove; sysdep.c's emacs_abort now takes its place.
6751 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6752 'abort' changed to use 'emacs_abort'.
6753 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6754 (abort) [!defined abort]: Rename to ...
6755 (emacs_abort): ... new name.
6756 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6757 the place of the old 'abort' in emacs.c.
6758 * w32.c, w32fns.c (abort): Do not #undef.
6759 * w32.c (emacs_abort): Rename from w32_abort.
6761 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6763 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6764 offsets[j].dv, since the y axis of the screen coordinates points
6765 down, while the y axis of the font definition coordinates points
6766 up. This fixes display of Arabic diacritics such as KASRA and
6767 KASRATAN. (Bug#11860)
6769 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6771 Be more systematic about _setjmp vs setjmp.
6772 * alloc.c (test_setjmp, mark_stack):
6773 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6774 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6775 (png_load, my_error_exit, jpeg_load):
6776 * process.c (send_process_trap, send_process):
6777 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6778 The underscored versions are up to 30x faster on some hosts.
6779 Formerly, the code used setjmp+longjmp sometimes and
6780 _setjmp+_longjmp at other times, with no particular reason to
6781 prefer setjmp+longjmp.
6783 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6785 Fix minor problem found by static checking.
6786 * buffer.c (Fdelete_all_overlays): Return nil.
6788 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6790 * buffer.c (Fdelete_all_overlays): New function.
6792 2012-09-03 Chong Yidong <cyd@gnu.org>
6794 * gtkutil.c: Add extern decl for Qxft.
6796 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6798 * emacs.c, eval.c: Use bool for boolean.
6799 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
6800 (malloc_using_checking) [DOUG_LEA_MALLOC]:
6801 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
6802 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
6803 (main, decode_env_path, Fdaemon_initialized):
6804 * eval.c (call_debugger, Finteractive_p, interactive_p):
6805 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
6806 (maybe_call_debugger, Fbacktrace):
6807 * process.c (read_process_output, exec_sentinel):
6808 Use bool for booleans.
6809 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
6810 All callers changed.
6811 * eval.c (interactive_p): Omit always-true boolean argument
6812 EXCLUDE_SUBRS_P. All callers changed.
6813 * dispextern.h, lisp.h: Reflect above API changes.
6814 * firstfile.c (dummy): Use the address of 'main', whose signature
6815 won't change, instead of the address of 'initialize', whose
6816 signature just changed from int to bool.
6817 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6818 * msdos.c (fatal_error_in_progress): ... from here.
6819 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6821 (redisplay_internal, unwind_redisplay): Simply clear
6822 REDISPLAYING_P when unwinding, instead of saving its previous,
6823 always-false value and then restoring it.
6825 Clean up some extern decls.
6826 Mostly, this hoists extern decls out of .c files and into .h files.
6827 That way, we're more likely to catch errors if the interfaces change.
6828 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6829 declare xg_mark_data.
6830 * dispextern.h (x_frame_parm_handlers):
6832 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
6833 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
6834 (Qultra_bold, Qoblique, Qitalic):
6835 Move extern decl here from .c file.
6836 * alloc.c (xg_mark_data) [USE_GTK]:
6838 * eval.c (Qlexical_binding):
6839 * fns.c (time) [!HAVE_UNISTD_H]:
6840 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
6841 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):

7039 for GCC 4.7.1 x86-64.
7041 2012-08-30 Glenn Morris <rgm@gnu.org>
7043 * lread.c (init_lread): For out-of-tree builds, only add the
7044 source directory's site-lisp dir to the load-path if it exists,
7045 consistent with in-tree builds. (Bug#12302)
7047 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

7281 It was meant to be temporary and it often doesn't work,
7282 because when IDX has side effects the behavior of IDX==IDX
7283 is undefined. See Stefan Monnier in

7292 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7294 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7295 as that's faster and simpler than static storage. Don't bother
7296 with the g_main_context_query overhead if g_main_context_pending
7297 says no events are pending.
7298 (gfds, gfds_size): Remove these static vars.
7299 (xgselect_initialize): Remove; no longer needed.
7300 All uses and decls removed.
7302 * emacs.c (fatal_error_signal_hook): Remove.
7303 All uses removed. This leftover from old code was always 0.
7305 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7306 * casefiddle.c (casify_object, casify_region):
7307 * casetab.c (set_case_table):
7308 * category.c, category.h (word_boundary_p):
7309 * category.h (CHAR_HAS_CATEGORY):
7310 Use bool for booleans, instead of int.
7312 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7314 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7316 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7318 On assertion failure, print backtrace if available.
7319 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7320 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7321 * Makefile.in (LIB_EXECINFO): New macro.
7324 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7325 * bytecode.c (exec_byte_code):
7326 * callint.c (check_mark, Fcall_interactively):
7327 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7328 (getenv_internal, sync_process_alive, call_process_exited):
7329 * lisp.h (USE_SAFE_ALLOCA):
7330 Use bool for booleans, instead of int.
7331 * lisp.h, process.h: Adjust prototypes to match above changes.
7332 * callint.c (Fcall_interactively): Don't assume the mark's
7333 offset fits in 'int'.
7335 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7337 * buffer.c, buffer.h: Use bool for boolean.
7338 * buffer.c (reset_buffer_local_variables)
7339 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7340 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
7341 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
7342 (overlay_touches_p, overlay_strings, Foverlay_put)
7343 (report_overlay_modification, call_overlay_mod_hooks):
7344 (mmap_enlarge, mmap_set_vars):
7345 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7346 Use bool for booleans, instead of int.
7347 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7348 since the 1-or-0 return value is always ignored anyway.
7349 (mmap_initialized_p):
7350 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7351 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7353 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7355 * bidi.c: Use bool for boolean.
7356 This is a bit more readable, and makes the text segment of bidi.o
7357 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7358 Presumably it's faster too.
7359 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7361 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7362 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7363 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7364 (bidi_explicit_dir_char, bidi_level_of_next_char)
7365 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7366 Use bool for booleans, instead of int.
7367 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7368 (bidi_unshelve_cache): Adjust decls to match code.
7370 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7372 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7375 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7377 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7378 * atimer.h: Include <stdbool.h>.
7380 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7382 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7383 compile time tests instead of run time tests on systems that do
7385 (FRAME_MAC_P): Remove leftover from deleted code.
7386 * frame.c (syms_of_frame): Remove leftover from deleted code.
7388 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7390 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7392 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7394 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7395 Otherwise, the compiler complains about (A?B:C) where B is void
7396 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7397 (fontset_add): Return void, for FONTSET_ADD.
7399 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7401 * alloc.c: Use bool for booleans.
7402 (gc_in_progress, abort_on_gc)
7403 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7404 (dont_register_blocks) [GC_MALLOC_CHECK]:
7405 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7406 (check_string_bytes, make_specified_string, memory_full)
7407 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7408 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7409 (mark_stack, valid_pointer_p, make_pure_string)
7410 (Fgarbage_collect, survives_gc_p, gc_sweep):
7411 Use bool for booleans, instead of int.
7412 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7413 Remove unused local.
7414 * alloc.c (PURE_POINTER_P):
7415 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7416 * editfns.c (Fformat):
7417 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7419 * fns.c (sweep_weak_table):
7420 * lisp.h (suppress_checking, push_message, survives_gc_p)
7421 (make_pure_string, gc_in_progress, abort_on_gc):
7422 * lread.c (readchar, read1):
7423 * print.c (Fprin1_to_string):
7424 * xdisp.c (push_message):
7425 Use bool for booleans affected directly or indirectly by
7428 Make recently-introduced setters macros.
7429 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7430 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7431 (set_fontset_default, set_fontset_fallback): Rename from their
7432 upper-case counterparts, and make them functions rather than macros.
7433 This is more consistent with the other recently-introduced setters.
7434 These don't need to be inline, since they're local.
7436 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7438 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7439 the loop (Bug#12247).
7441 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7443 * lisp.h (vcopy): Use memcpy rather than our own loop.
7444 This fixes a performance regression introduced by the recent
7445 addition of vcopy. This means 'vcopy' will need to be modified
7446 for a copying collector, but that's OK. Also, tighten the
7447 checking in the assertion.
7449 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7451 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7452 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7453 non-base glyph for the width of the base character, according to
7454 what x_draw_composite_glyph_string_foreground expects.
7455 Generate WADJUST value according to composition_gstring_width's
7456 expectations, to produce correct width of the composed character.
7457 Reverse the sign of the DU offset produced by ScriptPlace.
7459 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7461 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7463 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7465 Avoid direct writes to contents member of struct Lisp_Vector.
7466 * lisp.h (vcopy): New function to copy data into vector.
7467 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7468 * fns.c (Ffillarray): Use ASET.
7469 * keyboard.c (timer_check_2): Use AREF and ASET.
7470 (append_tool_bar_item, Frecent_keys): Use vcopy.
7471 * lread.c (read_vector): Use ASET.
7472 * msdos.c (Frecent_doskeys): Use vcopy.
7473 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7474 (Finternal_merge_in_global_face): Use ASET and vcopy.

7480 the position of its buffer's point.
7481 (Fset_window_point): For the selected window always go in its
7482 buffer to the specified position.
7484 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7486 Setter macros for fontsets.
7487 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7488 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7489 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7492 2012-08-20 Glenn Morris <rgm@gnu.org>
7494 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7495 Don't assume that `ln -f' works.
7497 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7499 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7500 and later about non-assignments with no effect. See discussion at
7501 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7504 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7506 Inline setter functions for Lisp_Objects slots of struct specbinding.
7507 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7510 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7512 * window.c (select_window): Always make selected window's buffer
7515 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7517 Use AREF and ASET for docstrings of category tables.
7518 * category.h (CATEGORY_DOCSTRING): Use AREF.
7519 (SET_CATEGORY_DOCSTRING): Use ASET.
7520 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7522 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7524 Inline setter functions for hash table members.
7525 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7526 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7527 (set_hash_key_and_value, set_hash_index, set_hash_next)
7528 (set_hash_hash): New functions.
7529 * charset.c, fns.c: Adjust users.
7531 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7533 Inline getter and setter functions for per-buffer values.
7534 * buffer.h (per_buffer_default, set_per_buffer_default)
7535 (per_buffer_value, set_per_buffer_value): New functions.
7536 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7537 * buffer.c, data.c: Adjust users.
7539 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7541 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7543 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7545 Rely on <config.h> + <unistd.h> to declare 'environ',
7546 as gnulib does this if the system doesn't.
7547 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7548 Remove declaration. MS-Windows declares it on stdlib.h which is
7549 included by conf_post.h.
7550 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7551 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7552 * vm-limit.c: Include <unistd.h>, for 'environ'.
7554 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7555 (start_of_data): Remove decl; mem-limits.h provides it.
7557 * xdisp.c (handle_invisible_prop): Make it a bit faster
7558 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7560 2012-08-19 Chong Yidong <cyd@gnu.org>
7562 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7565 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7567 * .gdbinit: Use call instead of set when calling a function in the
7570 * data.c (set_internal): Don't use set_blv_found.
7571 (Fkill_local_variable): Likewise.
7573 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7575 * nsfont.m (ns_ascii_average_width): Ensure the string
7576 ascii_printable is initialized with a null-terminated character
7577 array. Otherwise, it can contain undesired extra characters.
7579 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7581 port new setting code to Sun C 5.8 2005/10/13
7582 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7583 Return void, not Lisp_Object. Otherwise, the compiler
7584 complains about (A?B:C) where B is void and C is Lisp_Object
7585 when compiling CHAR_TABLE_SET, due to the recent change to
7586 the API of sub_char_table_set_contents.
7588 2012-08-18 Chong Yidong <cyd@gnu.org>
7590 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7591 for the string case (Bug#3874).
7593 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7595 * buffer.h (BSET): Remove (Bug#12215).

7674 are compiled into code.
7675 (tset_param_alist): New setter function.
7677 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
7679 * keyboard.h (KSET): Remove (Bug#12215).

8418 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
8419 * w32.c (init_environment): Change the default values of many
8420 environment variables in dflt_envvars[] to NULL, to avoid pushing
8421 them into environment when they were not already defined.
8422 Remove the code that deletes site-lisp subdirectories from the default
8423 value of EMACSLOADPATH, as it is no longer needed.
8424 (check_windows_init_file): Now external, not static.
8425 Use Vload_path as is, without adding anything, as this function is now
8426 called when Vload_path is already set up.
8428 * w32.h (check_windows_init_file): Add prototype.
8430 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

8474 Remove unnecessary pointer casts.
8475 * alloc.c (record_xmalloc): New function.
8476 * lisp.h (record_xmalloc): New decl.
8477 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8478 more like a function. This is because the pointer cast is not
8479 needed. All uses changed.
8480 * print.c (print_string, print_error_message): Avoid length recalc.
8482 Improve fix for macroexp crash with debugging (Bug#12118).
8483 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8484 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8485 not supposed to be invoked from the garbage collector.

8487 (gc_aset): New function, which is like ASET but can be
8488 used in the garbage collector.

8517 with addition of handling of symlinks and support for 'lstat'.
8518 If possible, get file's attributes and security information by
8519 handle, not by name. Produce S_IFLNK bit for symlinks, when
8520 called from 'lstat'.
8521 (stat, lstat): New functions, call 'stat_worker'.
8522 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8523 symlinks when the underlying filesystem supports them.
8525 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8527 Fix macroexp crash on Windows with debugging (Bug#12118).
8528 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8529 checking subscripts; problem introduced with the recent
8530 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8531 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8532 since it's used in non-static inline functions now.
8534 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8535 Don't assume buffer size fits in 'int'. Remove unused local.

8555 * composite.c (COMPOSITE_INLINE):
8556 * dispnew.c (DISPEXTERN_INLINE):
8557 * sysdep.c (SYSTIME_INLINE):
8558 Define to EXTERN_INLINE, so that the corresponding functions
8559 are compiled into code.
8560 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8561 (INLINE_HEADER_END): New macros.
8562 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8582 hard-coding the path separator.
8584 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8586 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8587 This how ASET and AREF are supposed to work, and makes
8588 it easier to think about future improvements. See
8589 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8590 * charset.h (set_charset_attr): New function.

9059 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9061 Fast save_excursion_save and save_excursion_restore.
9062 * lisp.h (struct Lisp_Excursion): New data type.
9063 (PVEC_EXCURSION): New pseudovector type.
9064 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
9065 to deal with it. Adjust comments.

9080 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9081 emacs.c, as this is a more-suitable home. Had this been done earlier
9082 the fix for 12036 would have avoided some of the problems noted in
9083 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9084 would have been more obvious.
9085 * emacs.c: Do not include <verify.h>; no longer needed.
9086 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9087 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9088 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9089 Remove; now done in lisp.h.
9090 * lisp.h (PUBLISH_TO_GDB): New macro.

9094 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9095 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9096 not be usable in #if. This simplifies things.
9098 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9100 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

9105 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9106 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9107 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9108 Adjust to changes in lisp.h and emacs.c, by using
9109 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9110 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9111 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9112 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9113 instead of gdb_valbits.
9114 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9115 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9116 instead of gdb_array_mark_flag.
9117 (xboolvector): Get size from $->size, not $->header.size.
9118 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9119 (xreload, hook-run, hookpost-run): Remove.
9120 * emacs.c: Include <verify.h>.
9121 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9122 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9124 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9125 (gdb_USE_LSB_TAG): New enum constants.
9126 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9127 Also define these as enum constants, so they're visible to GDB.
9128 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9129 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9130 as constants, so they're visible to GDB.

9132 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9133 Now enum constants, not macros, so they're visible to GDB.
9134 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9135 more convenient now. All uses changed.
9136 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9137 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9139 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

9146 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9147 add argument, tune behavior, and adjust all callers.
9149 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9151 Use typedef for EMACS_INT, EMACS_UINT.
9152 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9153 than macros. This simplifies debugging in the usual case, since
9154 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9155 and it allows expressions involving EMACS_INT casts.
9156 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9158 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

9170 Adjust buffer text indirection counters at the end of Fkill_buffer.
9171 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9172 buffer is definitely dead. This should really fix an issue reported
9173 by Christoph Scholtes again. (Bug#12007).
9174 (init_buffer_once): Initialize indirection counters of
9175 buffer_defaults and buffer_local_symbols (for sanity and safety).
9177 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9179 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9180 and continuation glyphs on tooltip frames, leave them at zero.

9208 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9210 Swap buffer text indirection counters in Fbuffer_swap_text.
9211 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9212 This avoids crash reported by Christoph Scholtes at
9213 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9215 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9217 * nsmenu.m (Popdown_data): New struct.

9240 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9242 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9243 as it's limited by the amount of memory, not by INT_MAX.
9245 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9247 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9248 in special-event-map. See the discussion at

9398 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9400 * eval.c (Fdefvar): Don't check constants since we only set the var if
9401 it's not yet defined anyway (bug#11904).
9403 * lisp.h (last_undo_boundary): Declare new var.
9404 * keyboard.c (command_loop_1): Set it.
9405 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
9406 were auto-added by the command loop (bug#11774).

9963 Move DONT_REOPEN_PTY to configure.
9965 * sound.c (DEFAULT_SOUND_DEVICE) [!WINDOWSNT]:
9966 * s/netbsd.h (DEFAULT_SOUND_DEVICE): Let configure set it.
9968 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
9970 Remove "#define unix" that is no longer needed (Bug#11905).
9971 * s/aix4-2.h (unix): Remove; no longer needed.
9973 EMACS_TIME simplification (Bug#11875).
9974 This replaces macros (which typically do not work in GDB)
9975 with functions, typedefs and enums, making the code easier to debug.
9976 The functional style also makes code easier to read and maintain.
9977 * systime.h: Include <sys/time.h> on all hosts, not just if
9978 WINDOWSNT, since 'struct timeval' is needed in general.
9979 (EMACS_TIME): Now a typedef, not a macro.
9980 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
9982 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
9983 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)

9986 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
9987 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
9988 which are not functions. All uses rewritten to use:
9989 (make_emacs_time): New function.
9990 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
9991 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
9992 not functions. All uses rewritten to use the following, respectively:
9993 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
9994 (add_emacs_time, sub_emacs_time): New functions.
9995 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
9996 * fileio.c (Fcopy_file):
9997 * xterm.c (XTflash): Get the current time closer to when it's used.
9998 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

10004 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
10005 * frame.c (Fmake_terminal_frame):
10006 * gtkutil.c (get_utf8_string):
10008 * nsmenu.m (ns_update_menubar):
10009 * regex.c (regerror):
10010 Prefer memcpy to strncpy and strncat when either will do.
10011 * fileio.c (Fsubstitute_in_file_name):
10012 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
10013 (menu_separator_name_p):
10014 * nsmenu.m (ns_update_menubar):
10015 Prefer memcmp to strncmp when either will do.
10016 * nsterm.m: Include <ftoastr.h>.
10018 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10019 Prefer snprintf to strncpy.
10020 * nsterm.m (ns_term_init):
10021 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10022 * nsterm.m (ns_term_init):
10023 Avoid the need for strncpy, by using build_string or
10024 make_unibyte_string directly. Use dtoastr, not snprintf.
10025 * process.c (Fmake_network_process): Diagnose service names that
10026 are too long, rather than silently truncating them or creating
10027 non-null-terminated names.
10028 (Fnetwork_interface_info): Likewise, for interface names.
10029 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10030 Prefer sprintf to strncat.
10031 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
10032 Prefer vsnprintf to vsprintf + strncpy.
10034 2012-07-10 Glenn Morris <rgm@gnu.org>
10036 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
10037 Clarify fallback case.
10039 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10041 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
10042 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
10043 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10044 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
10045 where argument type is known to be a Lisp_Cons.
10047 2012-07-10 Tom Tromey <tromey@redhat.com>
10049 * bytecode.c (BYTE_CODE_THREADED): New macro.
10050 (BYTE_CODES): New macro. Replaces all old byte-code defines.
10051 (enum byte_code_op): New type.
10052 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
10053 (exec_byte_code): Use them. Use token threading when applicable.
10055 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10057 Optimize pure C strings initialization.
10058 * lisp.h (make_pure_string): Fix prototype.
10059 (build_pure_c_string): New function, defined as static inline. This
10060 provides a better opportunity to optimize away calls to strlen when
10061 the function is called with compile-time constant argument.
10062 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10063 argument, adjust users accordingly. Use build_pure_c_string where
10065 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
10066 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10067 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
10069 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10071 Avoid calls to strlen in miscellaneous functions.
10072 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
10073 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
10074 * lread.c (openp): Likewise.
10076 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10078 Avoid calls to strlen in path processing functions.
10079 * fileio.c (file_name_as_directory): Add comment. Change to add
10080 srclen argument and return the length of result. Adjust users
10082 (directory_file_name): Fix comment. Change to add srclen argument,
10083 swap 1st and 2nd arguments to obey the common convention.
10084 Adjust users accordingly.
10085 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
10087 2012-07-10 Glenn Morris <rgm@gnu.org>
10089 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
10090 Move PENDING_OUTPUT_COUNT definition to configure.
10092 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
10093 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
10094 * s/gnu.h (DATA_START): Move definitions to configure.
10096 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10097 We include usg5-4-common.h, which defines them both.
10099 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10100 O_RDONLY already includes it).
10102 Stop ns builds setting the EMACSLOADPATH environment variable.
10103 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10104 Now it does not set EMACSLOADPATH, just returns the load-path string.
10105 * nsterm.h: Update accordingly.
10106 * lread.c [HAVE_NS]: Include nsterm.h.
10107 (init_lread) [HAVE_NS]: Use ns_load_path.
10108 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10110 2012-07-09 Glenn Morris <rgm@gnu.org>
10112 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10113 since the included bsd-common.h does so.
10115 Stop ns builds setting the EMACSPATH environment variable.
10116 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10117 (ns_init_paths): Do not set EMACSPATH.
10118 * nsterm.h (ns_exec_path): Add it.
10119 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10122 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10124 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10126 * process.c (wait_reading_process_output): 'waitchannels' was unset
10127 when read_kbd || !NILP (wait_for_cell); fix this.
10129 Add GCC-style 'const' attribute to functions that can use it.
10130 * character.h (char_resolve_modifier_mask):
10131 * keyboard.h (make_ctrl_char):
10132 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10133 (init_character_once, next_almost_prime, init_fns, init_image)
10134 (flush_pending_output, init_sound):
10135 * mem-limits.h (start_of_data):
10136 * menu.h (finish_menu_items):

10141 Add decls with ATTRIBUTE_CONST.
10143 Minor improvements to make_formatted_string.
10144 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10145 where int is good enough, as vsprintf returns an int.
10146 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10148 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10150 Use make_formatted_string to avoid double length calculation.
10151 * lisp.h (make_formatted_string): New prototype.

10159 * image.c (gs_load): Likewise.
10160 * minibuf.c (get_minibuffer): Likewise.
10161 * msdos.c (dos_set_window_size): Likewise.
10162 * process.c (make_process): Likewise.
10163 * xdisp.c (ensure_echo_area_buffers): Likewise.
10164 * xsettings.c (apply_xft_settings): Likewise.
10166 2012-07-09 Glenn Morris <rgm@gnu.org>
10168 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
10169 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
10170 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

10173 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10175 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10177 Move marker debugging code under MARKER_DEBUG.
10178 * marker.c (MARKER_DEBUG): Move marker debugging code under
10179 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10180 for bootstrap with --enable-checking (~3x slowdown reported
10181 by Juanma Barranquero <lekktu@gmail.com>).
10182 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10184 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10186 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10187 See <http://bugs.gnu.org/11825#29>.
10189 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10191 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10192 has no font, use the frame's font. (Bug#11813)
10193 (display_line): Add commentary about displaying truncation glyphs
10195 (produce_special_glyphs): Move here from term.c.
10197 * term.c (produce_special_glyphs): Move to xdisp.c.
10199 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10202 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10204 * xdisp.c (display_line): Avoid warning about implicit declaration
10207 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10209 * lisp.h: Remove empty conditional.
10211 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10213 * lread.c (load_path_check): Now static.
10215 Fix some minor --with-ns problems found by static checking.
10216 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10217 (x_set_font) [!HAVE_X_WINDOWS]:
10218 * image.c (xpm_load_image) [HAVE_NS]:
10219 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10220 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10221 Remove unused local.
10222 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10223 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10224 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10225 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10226 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10227 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10228 Fix pointer signedness problem.
10229 * xfaces.c (FRAME_X_FONT_TABLE):
10230 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10232 2012-07-07 Glenn Morris <rgm@gnu.org>
10234 * lread.c (load_path_check): New function, split from init_lread.
10235 (init_lread): Reorganize. Motivation:
10236 If EMACSLOADPATH is set, check/warn about that rather than the
10237 defaults, which we are not going to use. Hence we can remove
10238 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10239 Don't warn if site-lisp directories are missing.
10240 If not installed, start from a blank load-path, since
10241 PATH_LOADSEARCH refers to the eventual installation directories.
10243 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10245 Support truncation and continuation glyphs on GUI frames, when
10246 fringes are disabled. (Bug#11832)
10247 * xdisp.c (init_iterator): Get dimensions of truncation and
10248 continuation glyphs even if on GUI frames.
10249 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10250 or both, are absent.
10251 (start_display, move_it_in_display_line_to): Handle the case of a
10252 GUI frame without a fringe to display continuation or truncation
10254 (insert_left_trunc_glyphs): Support GUI frames: make sure
10255 truncation glyphs overwrite enough glyphs from the current line to
10256 have sufficient space in pixels.
10257 (display_line): Support truncation and continuation glyphs on GUI
10258 frames. If some spare pixels are left on the line after inserting
10259 the truncation glyphs, fill that space with a stretch glyph of a
10260 suitably computed width.
10262 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10263 produce_glyphs, to support GUI sessions.
10265 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10267 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10269 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10271 Do not require float-time's arg to fit in time_t (Bug#11825).
10272 This works better on hosts where time_t is unsigned, and where
10273 float-time is applied to the (negative) difference between two times.
10274 * editfns.c (decode_time_components): Last arg is now double *,
10275 not int *, and means to store all the result as a double, without
10276 worrying about whether the seconds part fits in time_t.
10277 All callers changed.
10278 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10279 All callers changed.
10280 (Ffloat_time): Do not fail merely because the specified time falls
10281 outside of time_t range.
10283 2012-07-07 Glenn Morris <rgm@gnu.org>
10285 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10286 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10287 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10289 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10291 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10292 Update dependencies.
10294 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10296 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10298 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

10300 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10301 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10302 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10303 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10305 * xfont.c (compare_font_names): Redo to omit the need for casts.
10307 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10309 * xfns.c (Fx_change_window_property): Doc fix.
10310 * w32fns.c (Fx_change_window_property): Doc fix.
10312 * w32fns.c (Fx_window_property): Accept the same arguments as the
10313 X Windows version. Doc fix.
10314 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10316 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10317 Eli Zaretskii <eliz@gnu.org>
10319 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10320 Windows-specific code from nt/config.nt moved here.
10321 Obsolete settings removed.
10323 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10325 * process.c: Avoid unnecessary calls to gettime.
10326 (wait_reading_process_output): Don't get the time of day
10327 when gobbling data immediately and not waiting, as there's no need
10328 for it in that case. This removes a FIXME.
10330 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10332 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10333 is defined (Bug#11768).
10335 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10337 Fix marker debugging code.

10339 if buffer is not multibyte.
10340 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10341 Call byte_char_debug_check with correct arguments.
10343 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10345 Compile marker debugging code only if ENABLE_CHECKING is defined.
10346 * marker.c (byte_char_debug_check, count_markers):
10347 Use only if ENABLE_CHECKING is defined.
10348 (byte_debug_flag): Remove.
10349 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10350 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10352 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10354 Avoid code repetition in marker-related functions.

10377 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10378 (save_restriction_save): Use build_marker.
10379 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10380 * window.c (save_window_save): Likewise.
10382 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10384 Do not use Fdelete_overlay in delete_all_overlays
10385 to avoid redundant calls to unchain_overlay.
10386 * buffer.c (drop_overlay): New function.
10387 (delete_all_overlays, Fdelete_overlay): Use it.
10388 * minibuf.c (get_minibuffer): Fix comment.
10390 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10392 Port to OpenBSD 5.1 amd64.
10393 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10394 This is needed for OpenBSD, and should be harmless on all BSD systems.
10395 Also, include <sys/sysctl.h>, as it should be available on all
10396 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10397 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10398 use p_pid member, not kp_proc.pid.
10400 2012-07-06 Glenn Morris <rgm@gnu.org>
10402 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10404 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10406 More xmalloc and related cleanup.
10407 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

10415 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10417 Omit needless casts involving void * pointers and allocation.
10418 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10419 as the former is more robust if P's type is changed.
10420 Prefer xzalloc to xmalloc + memset 0.
10421 Simplify malloc-or-realloc to realloc.
10422 Don't worry about xmalloc returning a null pointer.
10423 Prefer xstrdup to xmalloc + strcpy.
10424 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10426 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10427 alloca of a constant.
10429 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10431 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10432 hscroll is larger than the line width. Fixes long and futile
10433 looping inside extend_face_to_end_of_line (on a TTY) producing
10434 glyphs that are not needed and thrown away.
10436 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10438 * marker.c (set_marker_restricted_both): Simplify by using
10441 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10443 * editfns.c (region_limit): Simplify by using clip_to_bounds.
10445 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
10447 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
10448 not defined (Bug#11768).
10449 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
10450 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
10451 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
10452 followed by gtk_box_set_homogeneous (Bug#11768).
10453 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10454 (update_theme_scrollbar_width, xg_create_scroll_bar):
10455 Use gtk_scrollbar_new (Bug#11768).
10456 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
10457 (is_box_type): New function (Bug#11768).
10458 (xg_tool_item_stale_p): Call is_box_type.
10459 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10460 with default display (Bug#11768).
10462 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10464 * xdisp.c (window_hscroll_limited): New function.
10465 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10466 coordinates when window's hscroll is set to insanely large
10467 values. (Bug#11857)
10469 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
10471 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

10530 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10532 * fileio.c (time_error_value): Check the right error number.
10533 Problem reported by Troels Nielsen in
10534 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10536 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10538 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10539 This should be fixed in a better way; see Eli Zaretskii in
10540 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10541 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10543 * fileio.c (time_error_value): Rename from special_mtime.
10544 The old name's problems were noted by Eli Zaretskii in
10545 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10547 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10548 This variable's comment says Emacs needs at least one GDB-visible
10549 symbol of type enum pvec_type, to work around GDB problems.
10550 The symbol's value doesn't matter.
10552 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10553 that causes compilation to fail on pre-C99 compilers.
10555 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10557 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10558 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10560 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10562 * buffer.c (init_buffer_once): Fix initialization of
10563 headers for buffer_defaults and buffer_local_symbols.
10564 Reported by Juanma Barranquero <lekktu@gmail.com>.
10566 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10568 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10569 * lisp.h (enum pvec_type): Use fewer bits.
10570 (PSEUDOVECTOR_SIZE_BITS): New constant.
10571 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10572 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10573 change in pvec_type.
10574 (PSEUDOVECTOR_TYPEP): New macro.
10575 (TYPED_PSEUDOVECTORP): Use it.
10576 * fns.c (internal_equal): Adapt code to extract pvectype.
10577 * emacs.c (gdb_pvec_type): Update type.
10578 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10579 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10580 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10581 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10582 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10583 abusing vector->header.next.nbytes.
10584 (live_vector_p): Use PVEC_TYPE.
10585 (mark_object): Adapt code to extract pvectype. Use switch.
10587 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10589 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10590 Tighten new eassert a bit.
10592 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10594 Fix compilation with --enable-gcc-warnings and -O1
10595 optimization level.
10596 * doprnt.c (doprnt): Change type of tem to int, initialize
10597 to avoid compiler warning. Add eassert.
10598 * search.c (simple_search): Initialize match_byte to avoid
10599 compiler warning. Add eassert.
10601 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10603 Avoid weird behavior with large horizontal scrolls.
10604 Without this change, for example, large hscroll values would
10605 mess up Emacs's display on Fedora 15 x86, presumably due to
10606 overflows in int calculations in the display code.
10607 Also, if buffers had long lines, Emacs would freeze.
10608 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10609 (set_window_hscroll): New function, containing the old guts of
10610 Fset_window_hscroll. Return the clipped value.
10611 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10612 This avoids the need to check against PTRDIFF_MAX.
10614 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10616 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10618 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10620 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10622 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10623 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10624 since GCC 4.4.6 issues a bogus warning for them.
10626 Fix bugs in file timestamp newness comparisons.
10627 * fileio.c (Ffile_newer_than_file_p):
10628 * lread.c (Fload): Use full timestamp resolution of files,
10629 not just the 1-second resolution, so that files that are only
10630 slightly newer still count as newer.
10631 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10632 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10634 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10636 * fileio.c: Improve handling of file time marker. (Bug#11852)
10637 (special_mtime): New function.
10638 (Finsert_file_contents, Fverify_visited_file_modtime):
10639 Use it to set special mtime values consistently.
10641 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10643 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10644 marker for non-existing file. (Bug#11852)
10646 2012-07-03 Glenn Morris <rgm@gnu.org>
10648 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10649 and did not make it into globals.h).
10651 2012-07-03 Tom Tromey <tromey@redhat.com>
10653 * window.c (Fset_window_margins, Fset_window_fringes)
10654 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10655 * textprop.c (Fprevious_property_change): No longer static.
10656 * syntax.c (Fsyntax_table_p): No longer static.
10657 * process.c (Fget_process, Fprocess_datagram_address): No longer

10677 * dispextern.h: Remove EXFUNs.
10678 * intervals.h: Remove EXFUNs.
10679 * fontset.h: Remove EXFUN.
10680 * font.h: Remove EXFUNs.
10681 * dosfns.c (system_process_attributes): Remove EXFUN.
10682 * keymap.h: Remove EXFUNs.
10683 * lisp.h: Remove EXFUNs.
10684 * w32term.h: Remove EXFUNs.
10685 * window.h: Remove EXFUNs.
10686 * xsettings.h: Remove EXFUN.
10687 * xterm.h: Remove EXFUN.
10689 2012-07-03 Glenn Morris <rgm@gnu.org>
10691 * lisp.h (Frandom): Make it visible to C.
10692 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10693 buffer for invisible buffers. (Bug#1229)
10695 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10697 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10698 values which aren't power of 2.
10699 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10700 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10703 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10705 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10707 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10709 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10711 * alloc.c (allocate_vector_block): Remove redundant
10712 calls to mallopt if DOUG_LEA_MALLOC is defined.
10713 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10714 avoid calls to mallopt if zero_vector is returned.
10716 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10718 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10719 is enabled, avoid dereferencing NULL current_sblock if
10722 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10724 Cleanup basic buffer management.
10725 * buffer.h (struct buffer): Change layout to use generic vector
10726 marking code. Fix some comments. Change type of 'clip_changed'
10727 to bitfield. Remove unused #ifndef old.
10728 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10729 (GET_OVERLAYS_AT): Fix indentation.
10730 (for_each_per_buffer_object_at): New macro.
10731 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10732 (Fbuffer_local_variables): Use it.
10733 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
10734 * alloc.c (allocate_buffer): Adjust to match new layout of
10735 struct buffer. Fix comment.
10736 (mark_overlay): New function.
10737 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10738 Lisp area of struct buffer.
10739 (mark_object): Use it. Adjust marking of misc objects
10740 and related comments.
10742 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10744 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10745 wrapper that is not needed because the wrapped code is a no-op (zero
10746 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10747 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10749 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10751 * alloc.c (mark_buffer): Simplify. Remove prototype.
10752 (mark_object): Add comment. Reorganize marking of vector-like
10753 objects. Use CHECK_LIVE for all vector-like objects except buffers
10754 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10755 Avoid redundant calls to mark_vectorlike for bool vectors.
10757 2012-06-30 Glenn Morris <rgm@gnu.org>
10759 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10761 * epaths.in (PATH_SITELOADSEARCH): New.
10762 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10763 This is rather than relying on --enable-locallisppath elements
10764 having "site-lisp" in their names. (Bug#10208#25, 11658)
10766 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10768 * w32proc.c (sys_select): Accept and ignore one more argument.
10770 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10772 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10773 (pselect) [!MS_DOS]: Redirect to sys_select.
10775 * sysdep.c: Don't include dos.h and dosfns.h.
10777 * process.c (sys_select):
10778 * msdos.c (sys_select): Accept one more argument and ignore it.
10780 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10781 adapt data types and code to that.
10784 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10785 which clashes with the gnulib function of the same name.
10787 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10789 * font.c (font_style_to_value, font_style_symbolic)
10790 (font_prop_validate_style): Add type checks for values in
10793 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10795 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10798 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10800 * xdisp.c (try_window_id): Undo last change.
10802 * w32.c (getwd): Adjust commentary about startup_dir.
10803 (init_environment): Always call sys_access, even in non-MSVC
10804 builds. Don't chdir to the directory of the Emacs executable.
10805 This undoes code from 1997 which was justified by the need to
10806 "avoid conflicts when removing and renaming directories". But its
10807 downside was that every relative file name was being interpreted
10808 relative to the directory of the Emacs executable, which can never
10809 be TRT. In particular, it broke sys_access when called with
10810 relative file names.
10811 (sys_access): Map GetLastError to errno.
10813 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10815 * window.h (struct window): Change type of 'fringes_outside_margins'
10816 to bitfield. Fix comment. Adjust users accordingly.
10817 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10819 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10822 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10824 * gnutls.c (emacs_gnutls_handshake):

11003 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11005 Use sprintf return value instead of invoking strlen on result.
11006 In the old days this wasn't portable, since some sprintf
11007 implementations returned char *. But they died out years ago and
11008 Emacs already assumes sprintf returns int.
11009 Similarly for float_to_string.
11010 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

11017 * xfns.c (syms_of_xfns):
11018 Use sprintf or float_to_string result to avoid need to call strlen.
11019 * data.c (Fnumber_to_string):
11020 Use make_unibyte_string, since the string must be ASCII.
11021 * lisp.h, print.c (float_to_string): Now returns int length.
11022 * term.c (produce_glyphless_glyph):
11023 Use sprintf result rather than recomputing it.
11025 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
11026 * Makefile.in (ALL_CFLAGS):

11033 strcasecmp if available.

11054 * xfns.c (x_window): Remove redundant cast.
11056 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11058 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11059 `const char *' to `char *' to avoid compiler warning.
11061 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11063 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11064 instead of truncating it to 63 (admittedly a generous limit).
11066 * process.c: Fix spelling and caps in comments.

11119 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11121 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

11124 * keyboard.c (kbd_buffer_get_event):
11125 * process.c (Faccept_process_output):
11126 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11127 This improves on the previous patch, which introduced a bug
11128 when time_t is unsigned and as wide as intmax_t.
11129 See <http://bugs.gnu.org/9000#51>.
11131 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11160 language ID in the event parameters.
11162 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11163 event.code, not the obscure "character set ID".

11196 Support higher-resolution time stamps (Bug#9000).
11197 The time stamps are only nanosecond-resolution at the C level,
11198 since that's the best that any real-world system supports now.
11199 But they are picosecond-resolution at the Lisp level, as that's
11200 easy, and leaves room for future OS improvements.
11202 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11205 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11206 Don't get current time unless it's needed.
11208 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11209 now provides it if it's absent.
11210 (start_atimer): Port to higher-res time stamps.
11211 Check for time stamp overflow. Don't get current time more
11212 often than is needed.

11218 * dired.c: Include stat-time.h.
11219 (Ffile-attributes): File times now have higher resolution.
11221 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11222 (struct image): Timestamp now has higher resolution.
11224 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11225 has at least microseconds now. All uses removed.
11226 (update_frame, update_single_window, update_window, update_frame_1)
11227 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11228 (duration_to_sec_usec): Remove; no longer needed.

11236 (decode_time_components, lisp_seconds_argument): New functions.
11237 (make_time): Now static.
11238 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11239 Report an error if the time is invalid, rather than having the caller
11242 * fileio.c: Include <stat-time.h>
11243 (Fcopy_file): Copy higher-resolution time stamps.
11244 Prefer to set the time stamp via a file descriptor if that works.
11245 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11246 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11247 (Fvisited_file_modtime, Fset_visited_file_modtime):
11248 Support higher-resolution time stamps.
11250 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11252 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11254 * image.c (prepare_image_for_display, clear_image_cache)
11255 (lookup_image): Port to higer-resolution time stamps.
11257 * keyboard.c (start_polling, bind_polling_period):
11258 Check for time stamp overflow.
11259 (read_char, kbd_buffer_get_event, timer_start_idle)
11260 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11261 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11262 Port to higher-resolution time stamps. Do not assume time_t is signed.
11263 (decode_timer): New function. Timers are now vectors of length 9,
11264 not 8, to accommodate the picosecond component.
11265 (timer_check_2): Use it.
11267 * nsterm.m (select_timeout, timeval_subtract): Remove.
11268 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11269 as they're a bit more accurate and handle overflow better.
11270 (ns_select): Change prototype to be compatible with pselect.
11271 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11272 * nsterm.h (ns_select): Adjust prototype.
11274 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11275 us-resolution time stamps.
11276 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11278 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11280 * lisp.h (time_overflow): New decl.
11281 (wait_reading_process_output): First arg is now intmax_t, not int,
11282 to accommodate larger waits.
11284 * process.h (struct Lisp_Process.read_output_delay):
11285 Now counts nanoseconds, not microseconds.
11286 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11288 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11289 (wait_reading_process_output):
11290 Port to ns-resolution time stamps.
11291 (Faccept_process_output, wait_reading_process_output):
11292 Check for time stamp overflow. Do not assume time_t is signed.
11293 (select_wrapper): Remove; we now use pselect.
11294 (Fprocess_attributes): Now generates ns-resolution time stamps.
11296 * sysdep.c: Include utimens.h. Don't include utime.h
11297 or worry about struct utimbuf; gnulib does that for us now.
11298 (gettimeofday): Remove; gnulib provides a substitute.
11299 (make_timeval): New function.
11300 (set_file_times): Now sets ns-resolution time stamps.
11301 New arg FD; all uses changed.
11302 (time_from_jiffies, ltime_from_jiffies, get_up_time)

11304 Now returns ns-resolution time stamp. All uses changed.
11305 Check for time stamp overflow.
11307 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11308 provides a substitute now.
11310 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11311 since it guarantees struct timespec.
11312 (EMACS_TIME): Now struct timespec, so that we can support
11313 ns-resolution time stamps.
11314 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11315 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11316 (EMACS_USECS): Remove.
11317 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11318 so multiply the arg by 1000 before storing it.
11319 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11321 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

11328 (make_timeval, make_lisp_time, decode_time_components): New decls.
11329 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11330 that it mishandled time_t overflow. You can't compare by subtracting!
11331 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11332 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11334 * term.c: Include <sys/time.h>.
11335 (timeval_to_Time): New function, for proper overflow wraparound.
11336 (term_mouse_position, term_mouse_click): Use it.

11339 in the undo buffer.
11340 (Fprimitive_undo): Use them when restoring time stamps.
11342 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11343 (w32_get_internal_run_time):
11344 Port to higher-resolution Emacs time stamps.
11345 (ltime): Now accepts single 64-bit integer, as that's more convenient
11348 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11350 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11351 for compatibility with pselect. Support ns-resolution time stamps.
11353 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11355 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11356 Check for time stamp overflow, and support ns-resolution time stamps.
11358 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11359 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11360 (timeval_subtract): Remove; no longer needed.
11361 (XTflash, XTring_bell, x_wait_for_event):
11362 Port to ns-resolution time stamps. Don't assume time_t is signed.

11371 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11372 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11373 staticidx goes up to 1597 out of 1600 = 0x640.)
11375 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11377 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
11378 Otherwise, the umask might be mistakenly 0 while handling input signals.
11380 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
11382 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

11398 frame's selected window and its terminal's top-frame.
11399 (unwind_format_mode_line): Restore them.
11400 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11402 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11403 since tty frames can be explicitly named.
11404 (prepare_menu_bars): Likewise.
11406 * term.c (Ftty_top_frame): New function.
11408 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11410 Port byte-code-meter to modern targets.
11411 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11412 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11413 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11414 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

11421 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11423 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11424 gets killed during executing of this function (Bug#11665).
11425 Try to always return Qt when the buffer has been actually killed.
11426 (Vkill_buffer_query_functions): In doc-string say that functions
11427 run by this hook should not change the current buffer.
11429 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11431 Fix recently-introduced process.c problems found by static checking.
11432 * process.c (write_queue_push, write_queue_pop, send_process):

11451 * lisp.h (eassert): Assume C89 or later.
11452 This removes the need for CHECK.
11453 (CHECK): Remove. Its comments about always evaluating its
11454 argument were confusing, as 'eassert' typically does not evaluate
11457 * coding.c (produce_chars): Use ptrdiff_t, not int.
11459 * xterm.c (x_draw_underwave): Check for integer overflow.
11460 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

11648 Use an inline function on all platforms when using the union type,

11736 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
11737 would generate the diagnostic "Making \302\247 buffer-local while
11740 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11742 * dispnew.c (showing_window_margins_p): Undo last change, which
11743 was done due to an inadvertent commit.
11744 (adjust_frame_glyphs_for_frame_redisplay): Do call
11745 showing_window_margins_p.
11747 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
11749 * eval.c (Fmake_var_non_special): New primitive.

11753 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
11755 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
11756 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
11758 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11760 * alloc.c (allocate_vectorlike): Fix last change.
11762 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
11764 Block-based vector allocation of small vectors.
11765 * lisp.h (struct vectorlike_header): New field `nbytes',
11766 adjust comment accordingly.
11767 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
11768 to denote vector blocks. Adjust users (live_vector_p,
11769 mark_maybe_pointer, valid_lisp_object_p) accordingly.
11770 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
11771 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),

11780 (sweep_vectors): New functions.
11781 (allocate_vectorlike): Return `zero_vector' as the only vector of
11782 0 items. Allocate new vector from block if vector size is less than
11783 or equal to VBLOCK_BYTES_MAX.
11784 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
11785 (init_alloc_once): Add call to init_vectors.
11787 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
11789 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
11791 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11793 * doprnt.c (doprnt): Truncate multibyte char correctly.
11794 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11795 would mishandle a string argument "Xc" if X was a multibyte
11796 character of length 2: it would truncate after X's first byte
11797 rather than including all of X.
11799 2012-06-06 Chong Yidong <cyd@gnu.org>
11801 * buffer.c (word_wrap): Doc fix.
11803 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

11815 binary via PaX flags if the paxctl utility is available.
11816 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
11817 Restore PaX flags to their default. (Bug#11398)
11819 2012-06-03 Chong Yidong <cyd@gnu.org>
11821 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
11822 buffer (Bug#11226).

11829 position is past the end of the mode line string.
11831 * buffer.c (buffer_local_value_1): New function, split from
11832 Fbuffer_local_value; can return Qunbound.
11833 (Fbuffer_local_value): Use it.
11834 (Vmode_line_format): Docstring tweaks.
11836 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

11842 * keyboard.c: Export real-this-command to Elisp.
11843 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
11844 and DEFVAR it. Update all users.
11846 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
11848 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11850 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11851 Convert pctcpu and pctmem to Lisp float properly.
11852 Let the compiler fold better, as 100.0/0x8000 is exact.
11854 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11856 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11859 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

11863 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11865 For a 'struct window', replace some Lisp_Object fields to
11866 bitfields where appropriate, remove unused fields.
11867 * window.h (struct window): Remove unused 'last_mark_x' and
11868 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11869 change its type from Lisp_Object to bitfield.
11870 Change type of 'force_start', 'optional_new_start',
11871 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11872 fields from Lisp_Object to bitfield. Adjust users accordingly.
11874 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11876 Pacify gcc -Wdouble-precision when using Xaw.
11877 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11878 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11879 Use 'float' consistently, rather than 'float' in most places
11880 and 'double' in a couple of places.
11882 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11884 * xdisp.c (handle_stop): Detect whether we have overlay strings
11885 loaded by testing it->current.overlay_string_index to be
11886 non-negative, instead of checking whether n_overlay_strings is
11887 positive. (Bug#11587)
11889 2012-05-31 Chong Yidong <cyd@gnu.org>
11891 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11895 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11897 * search.c (search_buffer): Remove calls to
11898 r_alloc_inhibit_buffer_relocation, as it is now called by
11899 maybe_unify_char, which was the cause of relocation of buffer text
11902 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11904 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11905 for the duration of call to load_charset, to avoid problems with
11906 callers of maybe_unify_char that access buffer text through C
11909 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11910 decrement the inhibition flag, instead of just setting or
11913 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11915 Remove obsolete '#define static' cruft.
11916 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11917 This #undef was "temporary" in 2000; it is no longer needed
11918 now that '#define static' has gone away.
11919 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11920 (gray_bitmap_bits): Remove; no longer needed.
11921 All uses replaced with definiens.
11922 * xterm.c: Include "bitmaps/gray.xbm".
11924 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>

11927 The following changes affect the code only when profiling.
11928 * dispnew.c (__executable_start): Rename from safe_bcopy.
11929 Define only on platforms that need it.
11930 * emacs.c: Include <sys/gmon.h> when profiling.
11931 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11932 (__executable_start): Remove decl, since lisp.h does it now.
11933 (safe_bcopy): Remove decl; no longer has that name.
11934 (main): Coalesce #if into single bit of code, for simplicity.
11935 Cast pointers to uintptr_t, since standard libraries want integers
11937 * lisp.h (__executable_start): New decl.
11939 2012-05-31 Glenn Morris <rgm@gnu.org>
11941 * image.c (Fimagemagick_types): Doc fix.

11962 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11964 Do not create empty overlays with the evaporate property (Bug#9642).
11965 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11966 Bug#9642, but explicitly check that the buffer the overlay would
11967 be moved to is live and rearrange lines to make sure that errors
11968 will not put the overlay in an inconsistent state.
11969 (Fdelete_overlay): Cosmetics.
11971 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11973 * w32term.c (my_bring_window_to_top): New function.
11974 (x_raise_frame): Use handle returned by DeferWindowPos, which
11975 could be different from the original one.
11976 Call my_bring_window_to_top instead of my_set_foreground_window.

11985 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11987 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11988 This avoids undefined behavior that might cause the eassert
11989 to not catch an out-of-range value.
11991 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11993 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11994 Update dependencies.
11996 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11998 * bidi.c (bidi_mirror_char): Fix last change.
12000 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

12005 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
12007 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12008 Only r_alloc_inhibit_buffer_relocation needed to be added;
12009 the others were already declared.
12011 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12012 before checking whether it's out of range. Put the check inside
12014 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12016 2012-05-27 Ken Brown <kbrown@cornell.edu>
12018 * callproc.c (Fcall_process): Restore a line that was accidentally
12019 commented out in the 2011-02-13 change (bug#11547).
12021 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12023 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12024 defined on ralloc.c.
12026 * buffer.c [REL_ALLOC]: Remove prototypes of
12027 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12028 they are now on lisp.h.
12030 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12032 * search.c (search_buffer): Use it to inhibit relocation of buffer
12033 text while re_search_2 is doing its job, because re_search_2 is
12034 passed C pointers to buffer text. (Bug#11519)
12036 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12037 Update value to 24.
12039 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12040 state after an additional call to move_it_in_display_line_to, keep
12041 the values of it->max_ascent and it->max_descent found for the
12043 (pos_visible_p): Revert the comparison against bottom_y to what it
12044 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12047 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12049 Fix coding-related core dumps with gcc -ftrapv.
12050 The code was computing A - B, where A and B are pointers, and B is
12051 random garbage. This can lead to core dumps on platforms that
12052 have special pointer registers, and it also leads to core dumps on
12053 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12054 A - B only when B is initialized properly.
12055 * coding.c (coding_set_source, coding_set_destination): Return void.
12056 (coding_change_source, coding_change_destinations): New functions,
12057 with the old behaviors of coding_set_source and coding_set_destination.
12058 All callers that need an offset changed to use these new functions.
12060 2012-05-26 Glenn Morris <rgm@gnu.org>
12062 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)

12067 * xdisp.c (draw_row_with_mouse_face):
12068 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12070 * w32console.c: Include window.h.
12071 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12073 (initialize_w32_display): Initialize mouse-highlight data.
12075 * w32inevt.c: Include termchar.h and window.h.
12076 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12077 moves, call note_mouse_highlight. If help_echo changed, call
12078 gen_help_event to produce help-echo message in the echo area.
12079 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12082 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12084 * lread.c (read1): Simplify slightly to avoid an overflow warning
12085 with GCC 4.7.0 on x86-64.
12087 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12089 * bidi.c (bidi_mirror_char): Revert last change: an int is
12090 definitely wide enough here.
12092 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12094 Fix integer width and related bugs (Bug#9874).

12101 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
12102 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
12104 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12105 (allocate_pseudovector):
12106 Use int, not EMACS_INT, where int is wide enough.
12107 (inhibit_garbage_collection, Fgarbage_collect):
12108 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12109 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12110 int might not be wide enough.
12111 (bidi_cache_search, bidi_cache_find, bidi_init_it)
12112 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
12113 (bidi_at_paragraph_end, bidi_find_paragraph_start)
12114 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
12115 (bidi_level_of_next_char, bidi_move_to_visually_next):
12116 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12117 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
12118 (Fkill_buffer, Fset_buffer_major_mode)
12119 (advance_to_char_boundary, Fbuffer_swap_text)
12120 (Fset_buffer_multibyte, overlays_at, overlays_in)
12121 (overlay_touches_p, struct sortvec, record_overlay_string)
12122 (overlay_strings, recenter_overlay_lists)
12123 (adjust_overlays_for_insert, adjust_overlays_for_delete)
12124 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)

12126 (Foverlay_recenter, last_overlay_modification_hooks_used)
12127 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
12128 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12129 (validate_region): Omit unnecessary test for b <= e,
12130 since that's guaranteed by the previous test.
12131 (adjust_overlays_for_delete): Avoid pos + length overflow.
12132 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12133 (report_overlay_modification):
12134 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12135 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12136 Omit pointer cast, which isn't needed anyway, and doesn't work
12137 after the EMACS_INT -> ptrdiff_t change.
12138 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12139 * buffer.h: Adjust decls to match defn changes elsewhere.
12140 (struct buffer_text, struct buffer):
12141 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12142 Use EMACS_INT, not int, where int might not be wide enough.
12143 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12144 not int, to avoid needless 32-bit limit on 64-bit hosts.
12145 (exec_byte_code): Use tighter memory-full test, one that checks
12146 for alloca overflow. Don't compute the address of the object just
12147 before an array, as that's not portable. Use EMACS_INT, not
12148 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12149 * callint.c (Fcall_interactively):
12150 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12151 * callproc.c (call_process_kill, Fcall_process):
12152 Don't assume pid_t fits into an Emacs fixnum.

12160 * casefiddle.c (casify_object, casify_region, operate_on_word)
12161 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
12162 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12163 (casify_object): Avoid integer overflow when overallocating buffer.
12164 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12165 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12166 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12167 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12168 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
12169 integers are now checked earlier. All uses replaced with XINT.
12171 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12172 For CCL_MapSingle, check that content and value are in int range.
12173 (ccl_driver, Fregister_code_conversion_map):
12174 Check that Vcode_version_map_vector is a vector.
12175 (resolve_symbol_ccl_program): Check that vector header is in range.
12176 Always copy the vector, so that we can check its contents reliably
12177 now rather than having to recheck each instruction as it's being
12178 executed. Check that vector words fit in 'int'.
12179 (ccl_get_compiled_code, Fregister_ccl_program)
12180 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12181 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12182 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12183 contents are in range.
12184 (Fccl_execute_on_string): Check that status is in range.

12186 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):

12194 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12195 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12196 avoid mishandling large integers.

12207 Don't rely on undefined behavior with signed left shift overflow.
12208 Don't assume unsigned int fits into fixnum, or that fixnum fits
12209 into unsigned int. Don't require max_code to be a valid fixnum;
12210 that's not true for gb10830 4-byte on a 32-bit host. Allow
12211 invalid_code to be a cons, for the same reason. Require code_offset
12212 to be a character. Avoid int overflow if max_char is close
12214 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12215 this is intended anyway and avoids some undefined behavior.
12216 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12217 INDEX_TO_CODE_POINT, as that's what it expects.
12218 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12219 * charset.h (DECODE_CHAR): Return int, not unsigned;
12220 this is what was intended anyway, and it avoids undefined behavior.

12222 integer-overflow issues.
12223 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12224 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12225 where the argument is EMACS_INT, and this behavior is not intended.
12226 * chartab.c (Fmake_char_table, Fset_char_table_range)
12227 (uniprop_get_decoder, uniprop_get_encoder):
12228 Don't assume fixnum fits in int.
12229 * cmds.c (move_point): New function, that does the gist of

12233 (Fforward_line, Fend_of_line, internal_self_insert)

12837 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):
12838 (handle_tool_bar_click):
12839 Use int, not unsigned, since we prefer signed and the signedness
12840 doesn't matter here.
12841 (get_next_display_element, next_element_from_display_vector):
12842 Use int, not EMACS_INT, when int is wide enough.
12843 (start_hourglass): Use duration_to_sec_usec to do proper
12844 overflow checking on durations.
12845 * xfaces.c (Fbitmap_spec_p):
12846 Check that fixnums are in proper range for system types.
12847 (compare_fonts_by_sort_order):
12848 Avoid mishandling comparisons due to subtraction overflow.
12849 (Fx_family_fonts, realize_basic_faces):
12850 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12852 Don't assume fixnum fits in int.
12853 Use SAFE_ALLOCA_LISP, not alloca.
12854 (merge_face_heights): Remove unnecessary cast to EMACS_INT.
12855 (Finternal_make_lisp_face): Don't allocate more than MAX_FACE_ID.
12856 (face_at_buffer_position, face_for_overlay_string)
12857 (face_at_string_position):
12858 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12859 (merge_faces): Use int, not EMACS_INT, where int is wide enough.
12860 * xfns.c (x_set_menu_bar_lines, x_set_tool_bar_lines, x_icon_verify)
12862 Check that fixnums are in proper range for system types.
12863 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)
12864 (Fx_hide_tip, Fx_file_dialog, Fx_select_font):
12865 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12866 (Fx_change_window_property): Don't assume fixnums fit in int.
12867 * xfont.c (xfont_chars_supported):
12868 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12869 * xmenu.c (Fx_popup_dialog, set_frame_menubar)
12870 (create_and_show_popup_menu, create_and_show_dialog, xmenu_show):
12871 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12872 * xml.c (parse_region):
12873 * xrdb.c (magic_file_p):
12874 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12875 * xselect.c (TRACE1): Don't assume pid_t promotes to int.
12876 (x_get_local_selection, x_reply_selection_request)
12877 (x_handle_selection_request, wait_for_property_change):
12878 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12879 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
12880 short is wide enough.
12881 (x_send_client_event): Don't assume fixnum fits in int.
12882 * xterm.c (x_x_to_emacs_modifiers):
12883 Don't assume EMACS_INT overflows nicely into int.
12884 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12885 may come from Lisp.
12886 (handle_one_xevent): NATNUMP can eval its arg twice.
12887 (x_connection_closed):
12888 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12889 * xterm.h: Adjust decls to match defn changes elsewhere.
12890 (struct scroll_bar): Use struct vectorlike_header
12891 rather than rolling our own approximation.
12892 (SCROLL_BAR_VEC_SIZE): Remove; not used.
12894 2012-05-25 Glenn Morris <rgm@gnu.org>
12896 * lisp.mk (lisp): Update for more files being compiled now.
12898 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12900 * lread.c: Remove `read_pure' which makes no difference.
12901 (read_pure): Remove var.
12902 (unreadpure): Remove function.
12903 (readevalloop): Don't call read_list with -1 flag.
12904 (read1, read_vector): Don't test read_pure any more.
12905 (read_list): Simplify.
12907 * fileio.c, character.h: Minor style tweaks.
12909 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
12911 * window.h (clip_changed): Remove useless declaration.
12913 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
12915 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
12916 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12918 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12921 This directory predates autoconf and is no longer needed nowadays.
12922 Move its few remaining bits of functionality to where they're needed.
12923 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12924 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12925 * m/template.h: Remove.
12926 * Makefile.in (M_FILE): Remove. All uses removed.
12927 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12928 * lisp.h (USE_LSB_TAG):
12929 * mem-limits.h (EXCEEDS_LISP_PTR):
12930 Use VAL_MAX, not VALBITS, in #if.
12931 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12932 (EMACS_UINT): Define unconditionally now.
12933 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12934 (BITS_PER_EMACS_INT): New constants, replacing
12935 what used to be in config.h, but not useful in #if.
12936 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12937 define them any more.
12938 (VAL_MAX): New macro.
12940 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12941 BITS_PER_EMACS_INT, in #if.
12942 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12943 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12944 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12945 * s/ms-w32.h (DATA_START):
12946 Move here from removed file m/intel386.h.
12947 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12948 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12950 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12952 Assume C89 or later.
12953 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12954 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12956 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
12957 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
12958 * textprop.c, tparam.c (NULL): Remove.
12959 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
12960 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
12961 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
12962 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12963 * xterm.c (input_signal_count): Assume volatile works.
12965 2012-05-21 Ken Brown <kbrown@cornell.edu>
12967 * xgselect.c (xg_select): Fix first argument in call to 'select'
12970 2012-05-20 Ken Brown <kbrown@cornell.edu>
12972 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12973 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12975 2012-05-19 Ken Brown <kbrown@cornell.edu>
12977 * xfns.c (x_in_use): Remove `static' qualifier.
12978 * xterm.h (x_in_use): Declare.
12979 * xgselect.c: Include xterm.h.
12980 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12981 and `display_arg' (bug#9754).
12983 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12985 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12987 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12988 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12990 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12992 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12994 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12995 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12997 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12998 reference to image_cache->refcount.
12999 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
13001 2012-05-17 Juri Linkov <juri@jurta.org>
13003 * search.c (Fword_search_regexp, Fword_search_backward)
13004 (Fword_search_forward, Fword_search_backward_lax)
13005 (Fword_search_forward_lax): Move functions to isearch.el
13006 (bug#10145, bug#11381).
13008 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13010 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13012 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13014 * lread.c (init_obarray): Declare Qt and Qnil as special.
13016 2012-05-14 Glenn Morris <rgm@gnu.org>
13018 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13019 Put "libexec" before "bin", for the sake of init_callproc_1.
13021 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13023 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13025 * unexaix.c: Port to more-recent AIX compilers.
13026 (report_error, report_error_1, make_hdr, copy_sym)
13027 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13028 Make arguments const char *, not char *, to avoid violations of C
13029 standard and to fix some AIX warnings reported by Gilles Pion.
13031 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13033 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13034 already have overlays loaded.
13035 (handle_single_display_spec): Before returning without displaying
13036 fringe bitmap, synchronize the bidi iterator with the main display
13037 iterator, by calling iterate_out_of_display_property.
13038 (iterate_out_of_display_property): Detect buffer iteration by
13039 testing that it->string is a Lisp string.
13040 (get_next_display_element): When the current object is exhausted,
13041 and there's something on it->stack, call set_iterator_to_next to
13042 proceed with what's on the stack, instead of returning zero.
13043 (set_iterator_to_next): If called at the end of a Lisp string,
13044 proceed to consider_string_end without incrementing string
13045 position. Don't increment display vector index past the end of
13046 the display vector. (Bug#11417)
13047 (pos_visible_p): Don't report a position visible when move_it_to
13048 stopped at the last line of window, which happens to be scanned
13049 backwards by the bidi iteration. (Bug#11464)
13051 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13053 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13054 and right-margin display specs even if the spec is invalid or we
13055 are on a TTY, and thus unable to display on the fringes.
13056 That's because the text with the property will not be displayed anyway,
13057 so we need to signal to the caller that this is a "replacing"
13058 display spec. This fixes display when the spec is invalid or we
13061 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13063 * unexaix.c (make_hdr): Fix typo in prototype.
13064 This bug broke the build on AIX. Problem reported by Gilles Pion.
13066 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13068 * keyboard.c (kbd_buffer_get_event): Read special events also in
13069 batch mode. (Bug#11415)
13071 2012-05-12 Glenn Morris <rgm@gnu.org>
13073 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13075 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13077 * lisp.mk (lisp): Add newcomment.elc.
13079 2012-05-12 Glenn Morris <rgm@gnu.org>
13081 * Makefile.in (MKDIR_P): New, set by configure.
13082 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13084 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13086 Remove unused function hourglass_started.
13087 * dispextern.h (hourglass_started):
13088 * w32fns.c (hourglass_started):
13089 * xdisp.c (hourglass_started): Remove.
13091 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13093 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13094 Update dependencies.
13096 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13098 * xgselect.c (xg_select): Put maxfds+1 into a var.
13099 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13101 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13103 2012-05-10 Dave Abrahams <dave@boostpro.com>
13105 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13106 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13108 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13110 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13111 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13112 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13113 Initialize xd_registered_buses.
13115 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13117 Untag more efficiently if USE_LSB_TAG.
13118 This is based on a proposal by YAMAMOTO Mitsuharu in
13119 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13120 For an admittedly artificial (nth 8000 longlist) benchmark on
13121 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13122 Emacs's overall text size by 1%.
13123 * lisp.h (XUNTAG): New macro.
13124 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13125 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13126 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13127 * eval.c (Fautoload):
13128 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13129 * frame.h (XFRAME): Use XUNTAG.
13131 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13132 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13133 Remove unportable assumptions about print widths of types like
13135 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13136 intptr_t when converting between pointer and integer, to avoid GCC
13137 warnings about wrong width.
13139 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13141 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13142 stack for each reader_thread, instead of defaulting to 8MB
13143 determined by the linker. This avoids failures in creating
13144 subprocesses on Windows 7, see the discussion in this thread:
13145 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13147 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13149 Fix up display of the *Minibuf-0* buffer in the mini window.
13150 * keyboard.c (read_char): Don't clear the echo area if there's no
13152 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13153 contents of *Minibuf-0*) if there's no message displayed in its stead.
13155 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13157 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13160 2012-05-06 Chong Yidong <cyd@gnu.org>
13162 * lisp.mk (lisp): Update.
13164 2012-05-05 Jim Meyering <meyering@redhat.com>
13166 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13168 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13170 * data.c (PUT_ERROR): New macro.
13171 (syms_of_data): Use it. Add new error type `user-error'.
13172 * undo.c (user_error): New function.
13173 (Fprimitive_undo): Use it.
13174 * print.c (print_error_message): Adjust print style for `user-error'.
13175 * keyboard.c (user_error): New function.
13176 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13178 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13180 Do not limit current-time-string to years 1000..9999.
13181 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13182 (Fcurrent_time_string): Support any year that is supported by the
13183 underlying localtime representation. Don't use asctime, as it
13184 has undefined behavior for years outside the range -999..9999.
13186 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13188 Fix race conditions involving setenv, gmtime, localtime, asctime.
13189 Without this fix, interrupts could mess up code that uses these
13190 nonreentrant functions, since setting TZ invalidates existing
13191 tm_zone or tzname values, and since most of these functions return
13192 pointers to static storage.
13193 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13194 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13195 Grow the critical sections to include not just invoking
13196 localtime/gmtime, but also accessing these functions' results
13197 including their tm_zone values if any, and any related TZ setting.
13198 (format_time_string): Last arg is now struct tm *, not struct tm **,
13199 so that the struct tm is saved in the critical section.
13200 All callers changed. Simplify allocation of initial buffer, partly
13201 motivated by the fact that memory allocation needs to be outside
13202 the critical section.
13204 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13206 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13207 with RESET_INTERVAL.
13209 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13210 Remove duplicated buffer name initialization.
13212 2012-05-02 Jim Meyering <jim@meyering.net>
13214 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13216 * xfns.c (x_window): Use xstrdup (Bug#11375).
13218 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13220 * xdisp.c (pos_visible_p): If already at a newline from the
13221 display string before the 'while' loop, don't walk back the glyphs
13222 from it3.glyph_row. Solves assertion violation when the display
13223 string begins with a newline (egg.el). (Bug#11367)
13225 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13227 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13230 2012-05-01 Glenn Morris <rgm@gnu.org>
13232 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13233 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13234 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13235 All were removed before 23.1.
13237 * dispnew.c: Remove HAVE_LIBNCURSES test;
13238 it is always true on relevant platforms.
13240 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13241 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13243 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13245 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13247 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13248 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13251 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13253 Do not avoid creating empty evaporating overlays (Bug#9642).
13254 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13255 That is, do not delete an evaporating overlay if it becomes
13256 empty after its bounds are adjusted to fit within its buffer.
13257 This fix caused other problems, and I'm reverting it until we get
13258 to the bottom of them.
13260 2012-04-27 Chong Yidong <cyd@gnu.org>

13264 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13266 * xdisp.c (pos_visible_p): If the window start position is beyond
13267 ZV, start the display from buffer beginning. Prevents assertion
13268 violation in init_iterator when the minibuffer window is scrolled
13269 via the scroll bar.
13271 * window.c (window_scroll_pixel_based): Likewise.
13273 2012-04-27 Chong Yidong <cyd@gnu.org>

13284 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13285 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13287 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13289 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded

13294 (add_menu_item): If the call to AppendMenuW (via
13295 unicode_append_menu) fails, disable Unicode menus only if we are
13296 running on Windows 9X/Me.
13298 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13300 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13301 (xgetint): Add missing shift for LSB tags.

13321 Do not create empty overlays with the evaporate property (Bug#9642).
13322 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13323 if it becomes empty after its bounds are adjusted to fit within
13324 its buffer. Without this fix, in a nonempty buffer (let ((o
13325 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13326 yields an empty overlay that has the evaporate property, which is
13327 not supposed to happen.
13329 Fix minor GTK3 problems found by static checking.
13330 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

13350 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13351 (__malloc_size_t, __malloc_ptrdiff_t):
13352 Remove. All uses removed, replaced by the definiens if needed,
13353 since we can assume C89 or better now.

13371 Omit no-longer-needed casts.
13372 (valloc): Use getpagesize, not __getpagesize.
13373 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.

13442 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13444 * sysdep.c [__FreeBSD__]: Minor cleanups.
13445 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13446 Use Emacs indenting style more consistently. Avoid some casts.
13447 Use 'double' consistently rather than mixing 'float' and 'double'.
13449 2012-04-21 Eduard Wiebe <usenet@pusto.de>
13451 * sysdep.c (list_system_processes, system_process_attributes):
13452 Add implementation for FreeBSD (Bug#5243).

13458 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
13460 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
13461 It is never used otherwise.
13463 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13465 * print.c (print_preprocess): Only check print_depth if print-circle
13467 (print_object): Check for cycles even when print-circle is nil and

13472 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13473 set the status to "failed" and ensure that sentinel is run.
13475 2012-04-20 Glenn Morris <rgm@gnu.org>
13477 * process.c (Fset_process_inherit_coding_system_flag)
13478 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

13506 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
13507 -Wunused-result, -Wunused-variable. This should go away once
13508 the Emacs and Gnulib regex code is merged.

13528 New extern decls, to avoid calling undeclared functions.
13529 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13530 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13531 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13532 (NEED_MEM_INSERT): New macro.
13533 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13534 Remove one incorrect comment and fix another.

13601 2012-04-11 Daniel Colascione <dancol@dancol.org>
13603 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13604 against is gone. It's better to use vfork now so that when Cygwin
13605 gains a new, working vfork, we use it automatically (bug#10398).
13607 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

13628 being loaded (bug#10424).
13630 2012-04-09 Glenn Morris <rgm@gnu.org>
13632 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13633 not just in the obarray, before snarfing them. (Bug#11036)

13648 (emacs_gnutls_read): Use new log functions,
13649 `gnutls_handshakes_tried' process member, and
13650 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13651 attempts per process (connection).
13653 2012-04-09 Chong Yidong <cyd@gnu.org>
13655 * eval.c (Fuser_variable_p, user_variable_p_eh)

13657 (Fdefvar): Caller changed.
13659 * callint.c (Finteractive, Fcall_interactively):
13660 * minibuf.c (Fread_variable): Callers changed.
13662 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13664 * xdisp.c (set_cursor_from_row): If the display string appears in
13665 the buffer at position that is closer to point than the position
13666 after the display string, display the cursor on the first glyph of
13667 the display string. Fixes cursor display when a 'display' text
13668 property immediately follows invisible text. (Bug#11094)
13670 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13672 composite.c: use 'double' consistently
13673 * composite.c (get_composition_id): Use 'double' consistently
13674 instead of converting 'float' to 'double' and vice versa; this is
13675 easier to understand and avoids a GCC warning.
13677 2012-04-09 Glenn Morris <rgm@gnu.org>
13679 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13680 preparation for dumping it with emacs. (Bug#4789)

13701 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
13702 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13703 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13704 objects, as mark_maybe_pointer will catch them otherwise.
13705 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13706 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

13724 [!WINDOWSNT]: New macros.
13725 (init_libxml2_functions, libxml2_loaded_p): New functions.
13726 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13727 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13728 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13729 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13731 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13732 Call init_libxml2_functions before calling libxml2 functions.
13733 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13735 * emacs.c: Don't include libxml/parser.h.
13736 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13737 xmlCleanupParser directly.
13739 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13741 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13743 * indent.c (Fvertical_motion): If there is a display string at
13744 point, use it.vpos to compute how many lines to backtrack after
13745 move_it_to point. (Bug#11133)
13747 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13749 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13750 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13751 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13752 macros related to unification of CJK characters. For the details,
13753 see the discussion following the message here:
13754 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13756 2012-04-04 Chong Yidong <cyd@gnu.org>
13758 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13760 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13762 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13763 instead of alloca. (Bug#11138)
13765 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>

13770 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13772 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13773 position we get to after a call to move_it_to fails the
13774 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13775 only if we wind up in a string from display property. (Bug#11063)
13777 * window.c (Fdelete_other_windows_internal): Invalidate the row
13778 and column information about mouse highlight, so that redisplay
13779 restores it after reallocating the glyph matrices. (Bug#7464)
13781 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13782 string comes from a `display' text property, use the buffer
13783 position of that property as if we actually saw that position in
13785 (move_it_by_lines): Remove the assertion that
13786 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13787 violated when there's a before-string at the beginning of a line.
13790 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13792 * xdisp.c (append_space_for_newline): If the default face was
13793 remapped, use the remapped face for the appended newline.
13794 (extend_face_to_end_of_line): Use the remapped default face for
13795 extending the face to the end of the line.
13796 (display_line): Call extend_face_to_end_of_line when the default
13797 face was remapped. (Bug#11068)
13799 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13801 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13803 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13805 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13807 2012-03-27 Glenn Morris <rgm@gnu.org>
13809 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13812 2012-03-26 Kenichi Handa <handa@m17n.org>
13814 * dispextern.h (struct glyph): Fix previous change. Change the
13815 bit length of glyphless.ch to 25 (Bug#11082).

13819 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13820 (command_loop_1): Use it; inhibit selection update for
13821 handle-select-window too (Bug#8996).
13823 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13825 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13827 2012-03-25 Kenichi Handa <handa@m17n.org>
13829 * dispextern.h (struct glyph): Change the bit length of
13830 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13832 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13834 * s/ms-w32.h (tzname): Include time.h before redirecting to
13835 _tzname. Fixes the MSVC build. (Bug#9960)
13837 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13839 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13842 * xterm.c (XTread_socket): Only modify handling_signal if
13843 !SYNC_INPUT. (Bug#11080)
13845 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13847 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13848 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13849 when fetching a multibyte character consumes more bytes than
13850 CHAR_BYTES returns, due to unification of CJK characters in
13851 string_char. (Bug#11073)
13853 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13855 * process.c (wait_reading_process_output): Handle pty disconnect
13856 by refraining from sending oneself a SIGCHLD (bug#10933).

13864 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13865 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13867 2012-03-21 Chong Yidong <cyd@gnu.org>

13879 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13880 to reflect default non-nil value of redisplay-dont-pause.
13882 2012-03-19 Kenichi Handa <handa@m17n.org>
13884 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13885 it fit in a valid range (Bug#11003).
13887 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13889 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13890 that is not from display property, accept the row as a "cursor
13891 row" if one of the string's character has a non-nil `cursor'
13892 property. Fixes cursor positioning when there are newlines in
13893 overlay strings, e.g. in icomplete.el. (Bug#11035)
13895 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13897 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13899 2012-03-12 Chong Yidong <cyd@gnu.org>
13901 * eval.c (inhibit_lisp_code): Rename from
13902 inhibit_window_configuration_change_hook; move from window.c.
13904 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13905 * window.c (run_window_configuration_change_hook)
13906 (syms_of_window): Callers changed.

13926 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13929 2012-03-03 Glenn Morris <rgm@gnu.org>
13931 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13933 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13935 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13936 position past the first glyph_row that ends at ZV. (Bug#10902)
13937 (redisplay_window, next_element_from_string): Fix typos in
13939 (redisplay_window): Pass to move_it_vertically the margin in
13940 pixels, not in screen lines.
13942 2012-03-02 Glenn Morris <rgm@gnu.org>
13944 * buffer.c (buffer-list-update-hook): Doc fix.
13946 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13948 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13949 push_it before setting up the iterator for the first overlay
13950 string, even if we have an empty string loaded.
13951 (next_overlay_string): If there's an empty string on the iterator
13952 stack, pop the stack. (Bug#10903)
13954 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13956 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13957 Suggested by Stefan Monnier in
13958 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13959 * alloc.c (widen_to_Lisp_Object): New static function.
13960 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13961 and widening them to Lisp_Objects. This would work even if
13962 USE_LSB_TAG is defined and wide integers are used, which might
13963 happen in a future version of Emacs.
13965 2012-02-25 Chong Yidong <cyd@gnu.org>
13967 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13970 * xselect.c (Fx_selection_exists_p): Doc fix.

13972 before saving to clipboard manager.
13974 2012-02-24 Chong Yidong <cyd@gnu.org>
13976 * keyboard.c (process_special_events): Handle all X selection
13977 requests in kbd_buffer, not just the next one (Bug#8869).
13979 2012-02-23 Chong Yidong <cyd@gnu.org>
13981 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13982 call when setting menu-bar-lines and tool-bar-lines parameters.
13983 (unwind_create_frame_1): New helper function.

14004 when computing $valmask.
14006 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14007 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14008 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14009 It's useless in that case, and it can cause problems on hosts
14010 that allocate halves of EMACS_INT values separately.
14011 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14012 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14013 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14014 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14015 it avoids undefined behavior on hosts where shifting right by more
14016 than the word width has undefined behavior.
14018 2012-02-19 Chong Yidong <cyd@gnu.org>
14020 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14021 (Funhandled_file_name_directory, Ffile_name_as_directory)
14022 (Fdirectory_file_name, Fexpand_file_name)

14038 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14040 2012-02-15 Chong Yidong <cyd@gnu.org>
14042 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14043 marked as special. Also, starting docstrings with * is obsolete.

14058 2012-02-12 Chong Yidong <cyd@gnu.org>
14060 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14061 as that creates a dangerous corner case.
14063 * window.c (Fdelete_window_internal): Invalidate the mouse
14064 highlight (Bug#9904).
14066 2012-02-12 Glenn Morris <rgm@gnu.org>

14069 (Fx_get_selection_internal, Fx_disown_selection_internal)
14070 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
14071 * nsselect.m (Fx_own_selection_internal)
14072 (Fx_disown_selection_internal, Fx_selection_exists_p)
14073 (Fx_selection_owner_p, Fx_get_selection_internal):
14074 Sync docs and argument specs with the xselect.c versions.
14076 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
14078 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

14096 2012-02-07 Chong Yidong <cyd@gnu.org>
14098 * buffer.c (Fbuffer_local_variables)
14099 (buffer_lisp_local_variables): Handle unbound vars correctly;
14100 don't let Qunbound leak into Lisp.
14102 2012-02-07 Glenn Morris <rgm@gnu.org>
14104 * image.c (Fimagemagick_types): Doc fix.
14106 * image.c (imagemagick-render-type): Change it from a lisp object
14107 to an integer. Move the doc here from the lisp manual.

14134 2012-02-04 Eli Zaretskii <eliz@gnu.org>
14136 * keyboard.c (adjust_point_for_property): Don't position point
14137 before BEGV. (Bug#10696)
14139 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
14141 Handle overflow when computing char display width (Bug#9496).
14142 * character.c (char_width): Return EMACS_INT, not int.
14143 (char_width, c_string_width): Check for overflow when
14144 computing the width; this is possible now that individual
14145 characters can have unbounded width. Problem introduced
14146 by merge from Emacs 23 on 2012-01-19.
14148 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

14681 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
14682 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
14683 this macro definition.
14685 * s/ms-w32.h (tzname): Redirect to _tzname for all values of

14710 * xdisp.c (redisplay_window): If cursor row is not fully visible
14711 after recentering, and scroll-conservatively is set to a large
14712 number, scroll window by a few more lines to make the cursor fully
14713 visible and out of scroll-margin. (Bug#10105)
14714 (start_display): Don't move to the next line if the display should
14715 start at a newline that is part of a display vector or an overlay
14716 string. (Bug#10119)

14796 Otherwise, valgrind does not work on some platforms.
14797 Problem reported by Andreas Schwab in
14798 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
14799 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14800 is set, removing the need for VIRT_ADDRESS_VARIES.
14801 (PURE_P): Use a more-efficient implementation that needs just one
14802 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14803 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14804 to 4 (xorl, subq, cmpq, setbe).
14805 * alloc.c (pure): Always extern now, since that's the
14806 VIRT_ADDR_VARIES behavior.
14807 (PURE_POINTER_P): Use a single comparison, not two, for
14808 consistency with the new puresize.h.
14809 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14810 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
14811 Remove VIRT_ADDR_VARIES no longer needed.

14816 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14817 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14818 behave as if the cursor position were at the window margin.
14820 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14821 and the cursor position is out of bounds, behave as if the cursor
14822 position were at the window margin. (Bug#10075)
14824 2011-11-18 Chong Yidong <cyd@gnu.org>
14826 * window.c (Fwindow_combination_limit): Make first argument
14827 non-optional, since it is meaningless for live windows like the

14845 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
14847 * xdisp.c (row_hash): New function, body extracted from
14848 compute_line_metrics.
14849 (compute_line_metrics): Call row_hash, instead of computing the
14852 * dispnew.c (verify_row_hash): Call row_hash for computing the
14853 hash code of a row, instead of duplicating code from xdisp.c.
14855 * dispextern.h (row_hash): Add prototype.
14857 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14859 * frame.c (delete_frame): Don't delete the terminal when the last

14884 (recombine_windows, make_parent_window, make_window)
14885 (Fsplit_window_internal, saved_window)
14886 (Fset_window_configuration, save_window_save): Rename all
14887 occurrences of window_nest to window_combination_limit.
14889 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
14891 * image.c (imagemagick_load_image): Fix typo.
14893 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14895 * xdisp.c (display_line): Move the call to
14896 highlight_trailing_whitespace before the call to
14897 compute_line_metrics, since the latter needs to see the final
14898 faces of all the glyphs to compute ROW's hash value.
14899 Fixes assertion violations in row_equal_p. (Bug#10035)
14901 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14903 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
14904 just return (bug#10044).
14906 2011-11-12 Eli Zaretskii <eliz@gnu.org>
14908 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14909 with user-defined heap size. Bump the default size of the temacs
14910 heap to 27MB, to avoid memory warning when running temacs.
14911 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
14913 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14914 current_matrix and desired_matrix. (Bug#9990)
14915 (verify_row_hash) [XASSERTS]: New function.
14916 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
14917 that the hash value of glyph rows is correct.

14949 avoid a crash (bug#9496).
14951 2011-11-09 Chong Yidong <cyd@gnu.org>
14953 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

14960 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
14962 Avoid some portability problems by eschewing 'extern inline' functions.
14963 The trivial performance wins aren't worth the portability hassles; see
14964 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14966 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
14967 (window_box_width, window_box_left, window_box_left_offset)
14968 (window_box_right, window_box_right_offset): Undo previous change,
14969 by removing the "extern"s.
14970 * intervals.c (adjust_intervals_for_insertion)
14971 (adjust_intervals_for_deletion): Undo previous change,
14972 making these static again.
14973 (offset_intervals, temp_set_point_both, temp_set_point)
14974 (copy_intervals_to_string): No longer inline.
14975 * xdisp.c (window_text_bottom_y, window_box_width)

15015 This is also needed for porting to any host where GC_MARK_STACK is
15016 not GC_MAKE_GCPROS_NOOPS.
15017 (which_symbols): Use it.
15019 2011-11-07 Kenichi Handa <handa@m17n.org>

15032 * xmenu.c (cleanup_widget_value_tree): New function.
15033 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
15034 calling free_menubar_widget_value_tree directly (Bug#9830).
15036 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
15038 Fix some portability problems with 'inline'.
15039 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
15040 (window_box_width, window_box_left, window_box_left_offset)
15041 (window_box_right, window_box_right_offset): Declare extern.
15042 Otherwise, these inline functions do not conform to C99 and
15043 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15044 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15045 * intervals.c (adjust_intervals_for_insertion)
15046 (adjust_intervals_for_deletion): Now extern, because otherwise the
15047 extern inline functions 'offset_intervals' couldn't refer to it.
15048 (static_offset_intervals): Remove.
15049 (offset_intervals): Rewrite using the old contents of
15050 static_offset_intervals. The old version didn't conform to C99
15051 because an extern inline function contained a reference to an
15052 identifier with static linkage.

15118 official. Move initialization of image_cache_refcount and
15119 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

15158 * xdisp.c (note_mouse_highlight): If either of
15159 previous/next-single-property-change returns nil, treat that as
15160 the beginning or the end of the buffer. (Bug#9955)
15162 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
15164 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
15165 label is not null (Bug#9951).

15187 (mouse_face_from_buffer_pos, note_mouse_highlight):
15188 Rename cover_string to disp_string.

15198 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
15199 past the beginning of the current glyph matrix.
15201 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
15203 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.

15224 so that this new function doesn't get optimized away by a

15247 2011-10-29 Glenn Morris <rgm@gnu.org>
15249 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
15250 Not clear what it was for, and it causes various bugs. (Bug#9839)
15252 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15254 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
15255 possible random value that matches one of those tested as
15256 condition to clear the mouse face.
15258 2011-10-28 Chong Yidong <cyd@gnu.org>

15274 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15276 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
15277 <oslsachem@gmail.com> for helping to debug this.
15279 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

15285 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
15287 (w32font_open_internal, compute_metrics):
15288 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15289 instead of calling the "wide" APIs directly.
15291 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
15293 * w32.h (syms_of_w32font): Add prototype.
15295 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15297 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
15298 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
15299 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
15300 (Fmove_to_window_line): Doc fix.
15302 2011-10-27 Chong Yidong <cyd@gnu.org>
15304 * process.c (make_process): Set gnutls_state to NULL.
15306 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15307 non-NULL, regardless of GNUTLS_INITSTAGE.
15308 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
15309 an error. Set process slots as soon as we allocate them.
15311 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
15313 2011-10-27 Chong Yidong <cyd@gnu.org>
15315 * gnutls.c (emacs_gnutls_deinit): New function.

15320 (deactivate_process): Call emacs_gnutls_deinit.
15322 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15324 * image.c (x_create_x_image_and_pixmap):
15325 * w32.c (sys_rename, w32_delayed_load):
15326 * w32font.c (fill_in_logfont):

15332 extracted from Fw32_default_color_map.
15333 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
15335 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
15337 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
15339 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
15341 * keyboard.c (test_undefined): New function (bug#9751).
15342 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
15344 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
15346 * sysdep.c (init_sys_modes): Fix the check for the controlling
15347 terminal (Bug#6649).
15349 2011-10-20 Eli Zaretskii <eliz@gnu.org>
15351 * dispextern.h (struct bidi_it): New member next_en_type.
15353 * bidi.c (bidi_line_init): Initialize the next_en_type member.
15354 (bidi_resolve_explicit_1): When next_en_pos is valid for the
15355 current character, check also for next_en_type being WEAK_EN.
15356 (bidi_resolve_weak): Don't enter the expensive loop if the current
15357 position is before next_en_pos. Record the bidi type of the first
15358 non-ET, non-BN character we find, in addition to its position.
15359 (bidi_level_of_next_char): Invalidate next_en_type when
15360 next_en_pos is over-stepped.
15362 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15364 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15365 * editfns.c: Rewrite current-time-zone so that it invokes
15366 the equivalent of (format-time-string "%Z") to get the time zone name.
15367 This fixes a bug when the time zone name contains characters that
15368 need converting from the system time locale to Emacs internal format.
15369 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15370 that patch fixed format-time-string to do the conversion, but
15371 I forgot to fix current-time-zone.
15372 (format_time_string): New function, containing most of
15373 what Fformat_time_string used to contain.
15374 (Fformat_time_string): Rewrite in terms of format_time_string.
15375 This doesn't change this function's behavior.
15376 (current-time-zone): Rewrite to use format_time_string.
15377 This fixes the bug reported by Michael Schierl in
15378 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15379 Jason Rumney's 2007-06-07 change worked around this bug, but
15381 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15383 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15385 * xdisp.c (start_display): If the character at POS is displayed
15386 via a display vector, reset IT->current.dpvec_index to zero.
15387 (try_window_reusing_current_matrix): If a line ends in a display
15388 vector or the next line starts in a display vector, continue
15389 redrawing the window even though the character position of
15390 start_row was reached.
15393 2011-10-18 Chong Yidong <cyd@gnu.org>
15395 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15396 with nobreak-char-display too.
15398 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15400 Fix part 3 of bug#9771.
15401 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15402 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15403 non-neutral characters if the current character is a paragraph
15404 separator (a.k.a. Newline). This avoids running the same
15405 expensive loop twice, once when we consume the preceding newline
15406 and the other time when the line actually needs to be displayed.
15407 Avoid the loop when we see neutrals on the base embedding level
15408 following a character whose directionality is the same as the
15409 paragraph's. This avoids running the expensive loop when a line
15410 ends in a long sequence of neutrals, like control characters.
15411 Add assertion against STRONG_AL type. Slightly rearrange code
15412 that determines the type of a neutral given the first non-neutral
15414 (bidi_level_of_next_char): Set next_en_pos to zero when
15415 invalidating its info.
15417 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15419 * xdisp.c (push_display_prop): Determine whether to record string
15420 or buffer position by IT->string, not by IT->method. Allow
15421 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15422 (move_it_vertically_backward): Don't look for character position
15423 immediately after the newline when in a continuation line.
15426 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15428 * window.c (coordinates_in_window): Rewrite and delabelize
15429 vertical border check. (Bug#5357) (Bug#9618)
15431 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15433 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15434 errors in XSetWindowBorder (bug#9310).
15436 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15438 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15439 avoid crash when xmalloc overrun checking is enabled.
15441 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15443 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15444 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15445 cursor motion with <left> and <right> arrow keys.
15447 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15448 some callers set that themselves.
15450 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15452 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15453 display string and the previous row comes from the same string and
15454 is empty. (Bug#9739) (Bug#9738)
15456 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15458 * doc.c (get_doc_string): Encode file name (bug#9735).
15460 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15462 * bidi.c (bidi_level_of_next_char):
15463 * xdisp.c (get_visually_first_element): Remove old incorrect
15464 comments regarding the Unicode Line Separator character.
15466 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15468 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15470 * alloc.c (Fgc_status): Do not access beyond zombies array
15471 boundary if nzombies > MAX_ZOMBIES.
15472 * alloc.c (dump_zombies): Add missing format specifier.
15474 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15476 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15477 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15479 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15480 Some packages use them to denote characters with modifiers.
15482 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15484 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15485 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15486 matching a pp-number. Rename parameter var to var1.
15488 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15490 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15492 2011-10-08 Glenn Morris <rgm@gnu.org>
15494 * callint.c (Fcall_interactively): Give a more explicit error for the
15495 'c' case with a non-character input. (Bug#8479)
15497 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15499 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15501 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15502 lines that are hscrolled on the left.
15504 * dispnew.c (buffer_posn_from_coords): Account for a possible
15505 presence of header-line. (Bug#4426)
15507 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15509 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15510 Don't advertise functionality which we discourage or doesn't work.
15512 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15514 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15515 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15516 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15517 this makes Emacs dump core during garbage collection on rare
15518 occasions. sizeof is obviously inferior to offsetof here, so
15519 stick with offsetof.
15520 (GC_POINTER_ALIGNMENT): New macro.
15521 (mark_memory): Omit 3rd (offset) arg; caller changed.
15522 Don't assume EMACS_INT alignment is the same as pointer alignment.
15524 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15526 * keyboard.c (read_key_sequence_remapped): New var.
15527 (read_key_sequence): Compute remapping in the right buffer.
15528 (command_loop_1): Use read_key_sequence's remapping directly.
15530 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15532 * dired.c (file_name_completion): Don't expand file name.
15533 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15534 before checking file name handler.
15536 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15537 they've been requested explicitly (bug#9591).
15539 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15541 * keymap.c (Fsingle_key_description): Use make_specified_string
15542 instead of build_string to build string from push_key_description.
15545 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15547 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15548 This fixes a Y2038 bug on 64-bit hosts.
15549 * buffer.c (reset_buffer):
15550 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15551 (Fclear_buffer_auto_save_failure):
15552 Use 0, not -1, to represent an unset failure time, since time_t
15553 might not be signed.
15555 Remove dependency on glibc malloc internals.
15556 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15557 Move back here from lisp.h, but with their new implementations.
15558 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15559 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15560 * charset.c (charset_table_init): New static var.
15561 (syms_of_charset): Use it instead of xmalloc. This removes a
15562 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15563 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15564 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15565 Move back to alloc.c.
15566 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15567 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15569 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15571 * nsterm.m (windowDidResize): Call x_set_window_size only when
15572 ns_in_resize is true. Otherwise set pixelwidth/height and
15573 call change_frame_size (Bug#9628).
15575 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15577 Port --enable-checking=all to Fedora 14 x86-64.
15578 * charset.c (syms_of_charset): Also account for glibc malloc's
15579 internal overhead when calculating the initial malloc maximum.
15581 Port --enable-checking=all to Fedora 14 x86.
15582 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15584 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15585 (overrun_check_realloc, overrun_check_free):
15586 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15587 That way, xmalloc returns a properly-aligned pointer even if
15588 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15589 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15590 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15591 into account when calculating the initial malloc maximum.
15592 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15593 Move here from alloc.c, so that charset.c can use it too.
15594 Properly align; the old code wasn't right for common 32-bit hosts
15595 when configured with --enable-checking=all.
15596 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15597 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15599 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15601 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15604 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15606 * xdisp.c (compute_display_string_end): If there's no display
15607 string at CHARPOS, return -1.
15609 * bidi.c (bidi_fetch_char): When compute_display_string_end
15610 returns a negative value, treat the character as a normal
15611 character not covered by a display string. (Bug#9624)
15613 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15615 * lread.c (Fread_from_string): Fix typo in docstring.
15617 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15619 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15620 newline, reseat the iterator instead of bidi-iterating there one
15621 character at a time. (Bug#9610)
15622 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15623 TO_CHARPOS if the bidi iterator is at base embedding level.
15625 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15627 * lread.c (readevalloop): Use correct code for NBSP.
15628 (read1): Likewise. (Bug#9608)
15630 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15632 * dbusbind.c (Fdbus_register_signal): When service is not
15633 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15635 2011-09-25 Glenn Morris <rgm@gnu.org>
15637 * buffer.c (truncate-lines): Doc fix.
15639 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15641 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15642 (Fset_window_next_buffers): Doc fix.
15644 2011-09-24 Glenn Morris <rgm@gnu.org>
15646 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15648 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15650 Fix minor problems found by static checking.
15651 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15652 * indent.c (Fvertical_motion): Fix == vs = typo.
15654 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15656 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15657 Default value is now t. Doc fix.
15659 * indent.c (Fvertical_motion): Compute and apply the overshoot
15660 logic when moving up, not only when moving down. Fix the
15661 confusing name and values of the it_overshoot_expected variable;
15662 logic changes accordingly. (Bug#9254) (Bug#9549)
15664 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15665 CHARPOS is covered by a display string which includes newlines.
15666 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15667 is covered by a display string with embedded newlines.
15669 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15671 * dbusbind.c (Fdbus_register_signal): Add match rule to
15672 Vdbus_registered_objects_table. (Bug#9581)
15673 (Fdbus_register_method, Vdbus_registered_objects_table):
15676 2011-09-24 Jim Meyering <meyering@redhat.com>
15678 do not ignore write error for any output size
15679 The previous change was incomplete.
15680 While it makes emacs --batch detect the vast majority of stdout
15681 write failures, errors were still ignored whenever the output size is
15682 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15683 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15684 && echo FAIL: ignored write error
15685 FAIL: ignored write error
15686 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15687 && echo FAIL: ignored write error
15688 FAIL: ignored write error
15689 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15691 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15693 * emacs.c (Fkill_emacs): In noninteractive mode exit
15694 non-successfully if a write error occurred on stdout. (Bug#9574)
15696 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15698 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15701 * dispextern.h (struct it): Update the comment documenting what
15704 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15706 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15707 a display string, extend search for cursor position to end of row.
15708 (find_row_edges): If the row ends in a newline from a display
15709 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15710 Handle the case of a display string with multiple newlines.
15711 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15712 non-empty line. Fixes confusing cursor motion with arrow keys at
15713 the beginning of a line that starts with whitespace.
15715 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15717 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15720 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15722 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15723 boolean (Bug#9154).
15725 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15727 * xdisp.c (display_line): Record maximum and minimum buffer
15728 positions even if no glyphs were produced (e.g., by a zero-width
15729 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15730 buffer positions that will be removed from the glyph row because
15732 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15733 column is beyond frame width: don't subtract 1 "pixel" when
15734 computing width of the stretch.
15735 (reseat_at_next_visible_line_start): Undo the change made on
15736 2011-09-17 that saved paragraph information and restored it after
15737 the call to `reseat'. (Bug#9545)
15739 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15741 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15742 and turn window cursor on if cleared (Bug#9415).
15744 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15746 * search.c (boyer_moore): Take unibyte characters from pattern
15747 literally. (Bug#9458)
15749 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15751 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15753 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15755 Fix minor problem found by static checking.
15756 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15757 initialized, to pacify gcc -Wuninitialized.
15759 * fileio.c: Report proper errno when syscall falls.
15760 (Finsert_file_contents): Save and restore errno,
15761 so that report_file_error outputs the correct diagnostic.
15762 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15764 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15766 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15768 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15770 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15771 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15773 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15775 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15776 about the current paragraph and restore it after the call to reseat.
15778 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15779 (bidi_find_paragraph_start): Search back for paragraph beginning
15780 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15781 (bidi_move_to_visually_next): Only trigger paragraph-related
15782 computations when the last character is a newline or at EOB, not
15783 just any NEUTRAL_B. (Bug#9470)
15785 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15786 truncated lines if point is covered by a display string. (Bug#9524)
15788 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15790 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15791 (cons_to_x_long): New function.
15792 (lisp_data_to_selection_data): Use it. Correct the test for
15793 short-versus-long data; it was negated. Break out of vector
15794 loop, for efficiency, when a long datum is discovered.
15796 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15798 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15800 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15802 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15803 GCC PR/17406) by declaring this function with external scope.
15805 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15807 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15808 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15810 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15812 * editfns.c (Fformat): Correctly handle text properties on "%%".
15814 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15816 * xterm.c (x_draw_composite_glyph_string_foreground):

15818 * term.c (encode_terminal_code):
15819 * composite.c (composition_update_it, get_composition_id):
15820 * xdisp.c (get_next_display_element)
15821 (fill_composite_glyph_string): Add comments about special meaning
15822 of TAB characters in a composition.
15824 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15826 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15827 This occurs when processing a multibyte format.
15828 Problem reported by Wolfgang Jenker.
15830 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15832 * xdisp.c (try_cursor_movement): Only check for exact match if
15833 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15835 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15837 Remove unused external symbols.
15838 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15839 * xdisp.c (calc_pixel_width_or_height): Now static.
15840 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15841 * indent.c (check_display_width):
15842 * w32term.c: Fix comment to match code.
15843 * xterm.c, xterm.h (x_catching_errors): Remove.
15845 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15847 * xselect.c: Use signed conversions more consistently (Bug#9498).
15848 (selection_data_to_lisp_data): Assume incoming selection data are
15849 signed integers, not unsigned. This is to be consistent with
15850 outgoing selection data, which was modified to use signed integers
15851 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15852 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15853 expects long, not unsigned long.
15855 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15857 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15858 computation of loop end. Reported by Johan Bockgård
15861 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15863 * frame.c (Fother_visible_frames_p): Function deleted.
15865 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15867 * indent.c (compute_motion): Process display vector front to back
15868 rather than the other way around. (Bug#2496)
15870 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15872 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15874 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15876 * minibuf.c (Fread_from_minibuffer): Doc fix.
15878 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15880 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15881 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15883 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15885 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15886 value for non-existent files.
15888 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15890 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15891 set its "size" to -1. This will set the modtime_size field of
15892 the corresponding buffer to -1, which is what
15893 verify-visited-file-modtime expects for files that do not exist.
15896 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15898 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15900 * lisp.h: ... from here. push_key_description is no longer
15901 defined in keyboard.c, so its declaration should not be in
15902 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15903 logically belongs with push_key_description.
15905 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15907 * buffer.h: Include <sys/types.h> instead of <time.h>.
15908 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15909 Problem reported by Herbert J. Skuhra.
15911 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15913 * xml.c (parse_region): Make the parsing work for
15914 non-comment-starting XML files again (bug#9144).
15916 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15918 * image.c (gif_load): Fix calculation of bottom and right corner.
15921 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15923 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15924 redisplay in small windows.
15926 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15928 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15930 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15932 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15933 Operate on live windows only.
15935 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15937 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15939 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15941 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15942 only under bidi iteration.
15944 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15946 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15948 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15950 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15951 Without this fix, the command to link temacs failed due to an
15952 undefined symbol __builtin_isnan. This is because
15953 /usr/include/iso/math_c99.h #defines isnan(x) to
15954 __builtin_isnan(x), but the bundled gcc, which identifies itself
15955 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15957 * floatfns.c (isnan): #undef, and then #define to a clone of
15959 (Fisnan): Always define, since it's always available now.
15960 (syms_of_floatfns): Always define isnan at the Lisp level.
15962 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15964 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15966 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15968 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15969 The previous code assumed that file offsets (off_t values) fit in
15970 EMACS_INT variables, which is not true on typical 32-bit hosts.
15971 The code messed up by falsely reporting buffer overflow in cases
15972 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15973 when "big" contains more than 2**29 bytes, even though this
15974 inserts just one byte and does not overflow the buffer.
15975 (Finsert_file_contents): Store file offsets as off_t
15976 values, not as EMACS_INT values. Check for overflow when
15977 converting between EMACS_INT and off_t. When checking for
15978 buffer overflow or for overlap, take the offsets into account.
15979 Don't use EMACS_INT for small values where int suffices.
15980 When checking for overlap, fix a typo: ZV was used where
15981 ZV_BYTE was intended.
15982 (Fwrite_region): Don't assume off_t fits into 'long'.
15983 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15985 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15987 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15989 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15991 sprintf-related integer and memory overflow issues (Bug#9412).
15993 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15994 (esprintf, exprintf, evxprintf): New functions.
15995 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15996 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15997 (modify_event_symbol): Do not assume that the length of
15998 name_alist_or_stem is safe to alloca and fits in int.
15999 (Fexecute_extended_command): Likewise for function name and binding.
16000 (Frecursion_depth): Wrap around reliably on integer overflow.
16001 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16002 since some callers pass EMACS_INT values.
16003 (Fsingle_key_description): Don't crash if symbol name contains more
16004 than MAX_ALLOCA bytes.
16005 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16006 (get_minibuffer): Arg is now EMACS_INT, not int.
16007 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16008 (esprintf, exprintf, evxprintf): New decls.
16009 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16011 * dbusbind.c (signature_cat): New function.
16012 (xd_signature, Fdbus_register_signal):
16013 Do not overrun buffer; instead, report string overflow.
16015 * dispnew.c (add_window_display_history): Don't overrun buffer.
16016 Truncate instead; this is OK since it's just a log.
16018 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16019 even if the time zone offset is outlandishly large.
16020 Don't mishandle offset == INT_MIN.
16022 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16023 when creating daemon; the previous buffer-overflow check was incorrect.
16025 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16026 which has the guts of the old verror function.
16028 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16029 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16031 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16032 (font_unparse_xlfd): Don't blindly alloca long strings.
16033 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16034 fits in int, when using sprintf. Use single snprintf to count
16035 length of string rather than counting it via multiple sprintfs;
16036 that's simpler and more reliable.
16037 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16038 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16039 sprintf, in case result does not fit in int.
16041 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16042 (fontset_from_font): Print it.
16044 * frame.c (tty_frame_count): Now printmax_t, not int.
16045 (make_terminal_frame, set_term_frame_name): Print it.
16046 (x_report_frame_params): In X, window IDs are unsigned long,
16047 not signed long, so print them as unsigned.
16048 (validate_x_resource_name): Check for implausibly long names,
16049 and don't assume name length fits in 'int'.
16050 (x_get_resource_string): Don't blindly alloca invocation name;
16051 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16054 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16055 (xg_check_special_colors, xg_set_geometry):
16056 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16058 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16059 Use esprintf, not sprintf, in case result does not fit in int.
16061 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16062 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16063 it as a large positive number.
16064 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16065 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16067 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16068 in case result does not fit in int.
16070 * print.c (float_to_string): Detect width overflow more reliably.
16071 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16072 buffer overrun. Don't assume list length fits in 'int'. Treat
16073 print length of 0 as 0, not as infinity; to be consistent with other
16074 uses of print length in this function. Don't overflow print length
16075 index. Don't assume hash table size fits in 'long', or that
16076 vectorlike size fits in 'unsigned long'.
16078 * process.c (make_process): Use printmax_t, not int, to format
16079 process-name gensyms.
16081 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16083 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16084 to avoid potential buffer overrun.
16086 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16087 if X resource line is longer than 512 bytes.
16089 * xfns.c (x_window): Make sprintf buffer a bit bigger
16090 to avoid potential buffer overrun.
16092 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16094 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16096 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16098 Integer overflow fixes for scrolling, etc.
16099 Without these, Emacs silently mishandles large integers sometimes.
16100 For example, "C-u 4294967297 M-x recenter" was treated as if
16101 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16103 * xdisp.c (try_window_id): Check Emacs fixnum range before
16104 converting to 'int'.
16106 * window.c (window_scroll_line_based, Frecenter):
16107 Check that an Emacs fixnum is in range before assigning it to 'int'.
16108 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16109 values converted from Emacs fixnums.
16110 (Frecenter): Don't wrap around a line count if it is out of 'int'
16111 range; instead, treat it as an extreme value.
16112 (Fset_window_configuration, compare_window_configurations):
16113 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16115 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16116 that can exceed INT_MAX. Check that EMACS_INT value is in range
16117 before assigning it to the (possibly-narrower) index.
16118 (match_limit): Don't assume that a fixnum can fit in 'int'.
16120 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16123 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16124 (Fvertical_motion): Don't wrap around LINES values that don't fit
16125 in 'int'. Instead, treat them as extreme values. This is good
16126 enough for windows, which can't have more than INT_MAX lines anyway.
16128 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16130 * Require libxml/parser.h to avoid compilation warning.
16132 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16134 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16135 since this reportedly can destroy thread storage.
16137 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16139 * syntax.c (find_defun_start): Update all cache variables if
16140 exiting early (Bug#9401).
16142 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16144 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16146 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16147 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16148 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16150 * term.c (tty_append_glyph): New function.
16151 (produce_stretch_glyph): Static function and its prototype deleted.
16153 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16156 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16158 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16159 when checking :margin (Bug#9390).
16160 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16161 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16162 so that the name doesn't mislead. All uses changed.
16164 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16166 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16169 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16171 * xdisp.c (move_it_to): Don't bail out early when reaching
16172 position beyond to_charpos, if we are scanning backwards.
16173 (move_it_vertically_backward): When DY == 0, make sure we get to
16174 the first character in the line after the newline.
16176 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16178 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16179 (ccl_driver): Do not generate an out-of-range pointer.
16180 (Fccl_execute_on_string): Remove unnecessary check for
16181 integer overflow, noted by Stefan Monnier in
16182 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16183 Remove a FIXME that didn't need fixing.
16184 Simplify the newly-introduced buffer reallocation code.
16186 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16188 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16190 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16192 Integer and memory overflow issues (Bug#9196).
16194 * doc.c (get_doc_string): Rework so that
16195 get_doc_string_buffer_size is the actual buffer size, rather than
16196 being 1 less than the actual buffer size; this makes xpalloc more
16199 * image.c (x_allocate_bitmap_record, cache_image):
16200 * xselect.c (Fx_register_dnd_atom):
16201 Simplify previous changes by using xpalloc.
16203 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16204 since either will do and ptrdiff_t is convenient with xpalloc.
16206 * charset.c (charset_table_size)
16207 (struct charset_sort_data.priority): Now ptrdiff_t.
16208 (charset_compare): Don't overflow if priorities differ greatly.
16209 (Fsort_charsets): Don't assume list length fits in int.
16210 Check for size-calculation overflow when allocating sort data.
16211 (syms_of_charset): Allocate an initial charset table that is
16212 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16214 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16216 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16217 The actual value is always <= INT_MAX, and leaving it unsigned made
16218 overflow checking harder.
16220 * dispextern.h (struct glyph_matrix.rows_allocated)
16221 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16222 with xpalloc. The values are still always <= INT_MAX.
16224 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16226 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16227 (SAFE_NALLOCA): New macro.
16229 * region-cache.c (struct boundary.pos, find_cache_boundary)
16230 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16231 (set_cache_region, invalidate_region_cache)
16232 (revalidate_region_cache, know_region_cache, region_cache_forward)
16233 (region_cache_backward, pp_cache):
16234 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16235 so that ptrdiff_t * can be passed to xpalloc.
16236 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16237 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16238 (pp_cache): Don't assume cache_len fits in int.
16239 * region-cache.h: Adjust extern decls to match.
16241 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16242 EMACS_INT, since either will do, for xpalloc.
16244 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16245 (xnmalloc, xnrealloc, xpalloc): New functions.
16247 * bidi.c (bidi_shelve_header_size): New constant.
16248 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16249 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16251 * bidi.c (bidi_cache_shrink):
16252 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16254 Don't update size of array until after memory allocation succeeds,
16255 because xmalloc/xrealloc may not return.
16256 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16257 now that we have proper integer overflow checking.
16258 (record_overlay_string, overlay_strings): Catch overflows when
16259 calculating size of overlay_str_buf.
16261 * callproc.c (Fcall_process): Check for size overflow when
16262 calculating size of args2.
16263 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16264 Normally we prefer signed values, but sticking with ptrdiff_t would
16265 require adding more-complicated checks.
16267 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16268 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16269 Redo buffer-overflow calculations to avoid integer overflow.
16270 Add a FIXME comment where memory seems to be over-allocated.
16272 * character.c (Fstring): Check for size-calculation overflow.
16274 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16275 unnecessary integer overflow. Check for size overflow.
16276 (encode_coding_object): Don't update size until xmalloc succeeds.
16278 * composite.c (get_composition_id): Check for overflow in glyph
16279 length calculations.
16281 Integer and memory overflow fixes for display code.
16282 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16283 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16284 (scrolling_window): Check for overflow in size calculations.
16285 (line_draw_cost, realloc_glyph_pool, add_row_entry):
16286 Don't assume glyph table len fits in int.

16292 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16293 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

16296 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16297 (get_doc_string): Check for size calculation overflow.
16298 Don't update size until allocation succeeds.
16299 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16300 EMACS_INT, where ptrdiff_t will do.
16301 (Fsubstitute_command_keys): Check for string overflow.
16303 * editfns.c (set_time_zone_rule): Don't assume environment length
16305 (message_length): Now ptrdiff_t, not int.
16306 (Fmessage_box): Don't update size until allocation succeeds.
16307 Don't assume message length fits in int.
16308 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16310 * emacs.c (main): Do not reallocate argv, since there is a null at
16311 the end that can be overwritten, and this way there's no need to
16312 worry about size-calculation overflow.
16313 (sort_args): Check for size-calculation overflow.
16315 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16317 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16319 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16320 (x_set_scroll_bar_width, x_figure_window_size):
16321 Check for integer overflow.
16322 (x_set_alpha): Do not assume XINT fits in int.
16324 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16325 This is for the members text_lines, text_cols, total_lines, total_cols,
16326 where the system imposes an 'int' limit.
16328 * fringe.c (Fdefine_fringe_bitmap):
16329 Don't update size until alloc works.
16331 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16332 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16334 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16335 Check for size-calculation overflow.
16336 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16337 do, as we prefer signed integers.
16338 (id_to_widget.max_size, id_to_widget.used)
16339 (xg_store_widget_in_map, xg_remove_widget_from_map)
16340 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16341 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16342 Use and return ptrdiff_t, not int.
16343 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16344 * gtkutil.h: Change prototypes to match the above.
16346 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16347 are duplicate now that they've been promoted to lisp.h.
16348 (x_allocate_bitmap_record, x_alloc_image_color)
16349 (make_image_cache, cache_image, xpm_load):
16350 Don't update size until alloc is done.
16351 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)

16354 (ct_colors_allocated_max): New constant.
16355 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
16358 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
16359 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
16360 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
16361 Use ptrdiff_t, not int, to count maps.
16362 (read_char_minibuf_menu_prompt): Check for overflow in size
16363 calculations. Don't update size until allocation succeeds.
16364 Redo calculations to avoid overflow.
16365 * keyboard.h: Change prototypes to match the above.
16367 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
16369 (current_minor_maps): Check for size calculation overflow.
16370 * keymap.h: Change prototypes to match the above.
16372 * lread.c (read1, init_obarray): Don't update size until alloc done.
16374 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

16393 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16394 for command line length. Do not attempt to address one before the
16395 beginning of an array, as that's not portable.
16397 * term.c (max_frame_lines): Remove; unused.
16398 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
16400 (encode_terminal_code, calculate_costs): Check for size
16401 calculation overflow.

16423 Use ptrdiff_t, not int, for sizes.
16424 (Finternal_make_lisp_face, cache_face):
16425 Check for size calculation overflow.
16426 (cache_face): Treat size calculation overflows as if they were
16427 memory exhaustion (the usual treatment), rather than aborting.
16429 * xfns.c (x_encode_text, x_set_name_internal)
16430 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16431 sizes, since they can exceed INT_MAX in size. Check for size
16432 calculation overflow.
16434 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16435 (xg_select): Check for size calculation overflow.
16436 Don't update size until alloc done.
16438 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16439 as sprintf is limited to int lengths.
16441 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16442 (X_LONG_MIN): New macros.
16443 Use them to make the following changes clearer.
16444 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16445 This change doesn't affect the value now, but it may help remind
16446 future maintainers not to raise the value too much later.
16447 (SELECTION_QUANTUM): Remove, replacing with ...
16448 (selection_quantum): ... new function, which avoids overflow.
16450 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16451 assumption that selection length fits in 'int'.

16458 (receive_incremental_selection, x_property_data_to_lisp):
16459 Redo calculations to avoid overflow.
16460 (x_reply_selection_request): When sending hint, ceiling it at
16461 X_LONG_MAX rather than relying on wraparound overflow to send
16463 (x_get_window_property, receive_incremental_selection)
16464 (lisp_data_to_selection_data, x_property_data_to_lisp):
16465 Check for size-calculation overflow.
16466 (x_get_window_property, receive_incremental_selection)

16468 Don't store size until memory allocation succeeds.
16469 (x_get_window_property): Plug memory leak on memory exhaustion.
16470 Don't double-block input; malloc is safe here. Don't assume 2**34
16471 - 4 fits in unsigned long. Add an xassert to check
16472 XGetWindowProperty overflow. Be more careful about overflow
16473 calculations, and distinguish size from memory overflow better.
16474 (receive_incremental_selection): When tracing, don't assume
16475 unsigned int is less than INT_MAX.
16476 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16477 harmful) conversions of unsigned short to int.
16478 (lisp_data_to_selection_data): Don't assume that integers
16479 in the range -65535 through -1 fit in an X unsigned short.
16480 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16481 result parameters unless successful. Rely on cons_to_unsigned
16482 to report problems with elements; the old code wasn't right anyway.
16483 (x_check_property_data): Check for int overflow; we cannot use
16484 a wider type due to X limits.
16485 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
16487 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
16489 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
16490 (x_term_init): Check for size calculation overflow.
16491 (x_color_cells): Don't store size until memory allocation succeeds.
16492 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
16493 Don't assume alloca size is less than MAX_ALLOCA.
16494 (x_term_init): Don't assume length fits in int (sprintf is limited
16497 Use ptrdiff_t for composition IDs.
16498 * character.c (lisp_string_width):
16499 * composite.c (composition_table_size, n_compositions)
16500 (get_composition_id, composition_gstring_from_id):

16516 * image.c (xpm_get_color_table_h):
16517 * lisp.h (hash_lookup, hash_put):
16518 * minibuf.c (Ftest_completion):
16519 Use ptrdiff_t for hash table indexes, not int (which is too
16520 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16521 32-bit --with-wide-int hosts).
16523 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16524 Add a FIXME comment about memory leaks.
16525 (syms_of_charset): Don't assume xmalloc returns.

16529 * character.h (CHAR_WIDTH):
16530 * indent.c (MULTIBYTE_BYTES_WIDTH):
16531 Use sanitize_char_width to avoid undefined and/or bad behavior
16532 with outlandish widths.
16533 * character.h (sanitize_tab_width): Rename from sanitize_width,
16534 now that we have two such functions. All uses changed.
16535 (sanitize_char_width): New inline function.
16537 Don't assume that tab-width fits in int.
16538 * character.h (sanitize_width): New inline function.
16539 (SANE_TAB_WIDTH): New macro.
16540 (ASCII_CHAR_WIDTH): Use it.
16541 * indent.c (sane_tab_width): Remove. All uses replaced by
16542 SANE_TAB_WIDTH (current_buffer).

16545 * fileio.c: Integer overflow issues with file modes.
16546 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
16548 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
16549 Remove unreachable code.
16550 (read_hex, load_charset_map_from_file): Check for integer overflow.
16552 * xterm.c: Don't go over XClientMessageEvent limit.
16553 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16554 (x_send_scroll_bar_event): Likewise. Check that the size does not
16555 exceed limits imposed by XClientMessageEvent, as well as the usual
16556 ptrdiff_t and size_t limits.
16558 * keyboard.c: Overflow, signedness and related fixes.
16559 (make_lispy_movement): Use same integer type in forward decl
16560 that is used in the definition.
16561 (read_key_sequence, keyremap_step):
16562 Change bufsize argument back to int, undoing my 2011-03-30 change.
16563 We prefer signed types, and int is wide enough here.
16564 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16565 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16566 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16567 length, not size_t. Use ptrdiff_t for index, not int.
16568 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16569 possibility of integer overflow.
16571 Overflow, signedness and related fixes for images.
16573 * dispextern.h (struct it.stack[0].u.image.image_id)

16581 * xdisp.c (calc_pixel_width_or_height):
16582 * xfns.c (image_cache_refcount):
16583 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
16584 on typical 64-bit hosts.

16592 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
16593 (lookup_image): Remove unnecessary tests.
16594 (xbm_image_p): Locals are now of int, not EMACS_INT,
16595 since parse_image_check makes sure they fit into int.
16596 (png_load, gif_load, svg_load_image):
16597 Prefer int to unsigned where either will do.
16598 (tiff_handler): New function, combining the cores of the
16599 old tiff_error_handler and tiff_warning_handler.
16600 This function is rewritten to use vsnprintf and thereby avoid
16601 stack buffer overflows. It uses only the features of vsnprintf
16602 that are common to both POSIX and native Microsoft.
16603 (tiff_error_handler, tiff_warning_handler): Use it.
16604 (tiff_load, gif_load, imagemagick_load_image):
16605 Don't assume :index value fits in 'int'.
16606 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16607 (imagemagick_load_image): Check that crop parameters fit into
16608 the integer types that MagickCropImage accepts. Don't assume
16609 Vimagemagick_render_type has a nonnegative value. Don't assume
16610 size_t fits in 'long'.
16611 (gs_load): Use printmax_t to print the widest integers possible.
16612 Check for integer overflow when computing image height and width.
16614 2011-08-26 Eli Zaretskii <eliz@gnu.org>
16616 * xdisp.c (redisplay_window): Don't force window start if point
16617 will be invisible in the resulting window. (Bug#9324)

16621 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
16622 the display spec is of the form `(space ...)'.
16623 (handle_display_spec): Return the value returned by
16624 handle_single_display_spec, not just 1 or zero.
16625 (handle_single_display_spec): If the display spec is of the form
16626 `(space ...)', and specifies display in the text area, return 2
16628 (try_cursor_movement): Check for the need to scroll more
16629 accurately, and prefer exact match for point under bidi.
16630 Don't advance `row' beyond the last row of the window.
16632 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16633 into disp_prop; all users changed.
16635 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
16636 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
16637 for the text covered by the display property.

16647 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16648 buffers, return left-to-right.
16649 (set_cursor_from_row): Consider candidate row a win if its glyph
16650 represents a newline and point is on that newline. Fixes cursor
16651 positioning on the newline at EOL of R2L text within L2R
16652 paragraph, and vice versa.
16653 (try_cursor_movement): Check continued rows, in addition to
16654 continuation rows. Fixes unwarranted scroll when point enters a
16655 continued line of R2L text within an L2R paragraph, or vice versa.
16656 (cursor_row_p): Consider the case of point being equal to
16657 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16658 from the end of a short line to the beginning of a continued line
16659 of R2L text within L2R paragraph.
16660 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
16661 composed characters.

16676 2011-08-22 Kenichi Handa <handa@m17n.org>
16678 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
16679 extra slot even if the purpose is char-code-property-table.
16681 2011-08-23 Eli Zaretskii <eliz@gnu.org>
16683 * xdisp.c (redisplay_window): When computing centering_position,
16684 account for the height of the header line. (Bug#8874)
16686 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16687 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16688 candidate is selected by the mouse, and that candidate has a
16689 composed character under the mouse.
16691 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16692 coordinates reported by pos-visible-in-window-p for a composed
16693 character in column zero.
16695 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
16697 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
16699 2011-08-22 Eli Zaretskii <eliz@gnu.org>
16701 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16702 consider it a hit if to_charpos is anywhere in the range of the
16703 composed buffer positions.
16705 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16707 * image.c (gif_load): Don't assume that each subimage has the same
16708 dimensions as the base image. Handle disposal method that is
16709 "undefined" by the gif spec (Bug#9335).
16711 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16713 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
16714 (Fcondition_case): Document `debug' symbol in error handler.
16716 2011-08-19 Eli Zaretskii <eliz@gnu.org>
16718 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16719 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16720 from an Org mode buffer to a Speedbar frame.
16722 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16723 a composition, take its buffer position from IT->cmp_it.charpos.
16724 Fixes cursor positioning at the beginning of a line that begins
16725 with a composed character.
16727 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16729 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16730 character bidirectional type, use STRONG_L instead. Fixes crashes
16731 in a buffer produced by `describe-categories'.
16733 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16734 members before the level stack, so they would be saved and
16735 restored when copying iterator state. Fixes incorrect reordering
16736 around TABs covered by display properties.
16738 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16740 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16744 * eval.c (internal_condition_case, internal_condition_case_1)
16745 (internal_condition_case_2, internal_condition_case_n):
16746 Remove unnecessary aborts (Bug#9081).
16748 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16750 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16751 has no `load' handler, try opening the file locally. (Bug#9311)
16753 2011-08-16 Ken Brown <kbrown@cornell.edu>
16755 * gmalloc.c: Expand comment.

16759 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
16760 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
16762 2011-08-16 Ken Brown <kbrown@cornell.edu>
16764 Fix memory allocation problems in Cygwin build (Bug#9273).
16766 * unexcw.c ( __malloc_initialized): Declare external variable.
16767 (fixup_executable): Force the dumped emacs to reinitialize malloc.
16769 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
16771 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

16799 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
16800 coordinates of the iterator when restoring from ppos_it.
16803 2011-08-14 Kenichi Handa <handa@m17n.org>
16805 * process.c (create_process): Call setup_process_coding_systems
16806 after the pid of the process is set to -1 (Bug#8162).
16808 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16810 * xdisp.c (move_it_in_display_line_to): Don't invoke
16811 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16812 ppos_it. Fixes vertical cursor motion when line beginning is
16813 covered by an image. (Bug#9296)
16815 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16817 * nsterm.h (ns_run_ascript): Declare.
16818 (NSAPP_DATA2_RUNASSCRIPT): Define.
16820 * nsfns.m (as_script, as_result, as_status): New static variables.
16821 (ns_run_ascript): New function.
16822 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16823 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16824 the event loop. Get status from as_status (Bug#7276).
16826 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16827 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16828 the event loop (Bug#7276).
16830 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16832 * gnutls.c (QCgnutls_bootprop_priority)

16853 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16854 (Fnetwork_interface_list): Allocate in increments of bytes instead
16855 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16856 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16858 (struct ifflag_def): notrailers is smart on OSX.
16859 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16860 Get hardware address with getifaddrs if available.
16862 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16864 * xdisp.c (iterate_out_of_display_property): xassert that
16865 IT->position is set to within IT->object's boundaries. Break from
16866 the loop as soon as EOB is reached; avoids infloops in redisplay
16867 when IT->position is set up wrongly due to some bug.
16868 Set IT->current to match the bidi iterator unconditionally.
16869 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16870 entry. Force push_it to save on the stack the current
16871 buffer/string position, to be restored by pop_it. Fix flags in
16872 the iterator structure wrt the object coming from a display
16873 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16874 properties. (Bug#9284)
16876 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16878 * fontset.c (fontset_get_font_group): Add proper type checks.

16888 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16890 * xdisp.c (forward_to_next_line_start): Allow to use the
16891 no-display-properties-and-no-overlays under bidi display.
16892 Set disp_pos in the bidi iterator to avoid searches for display
16893 properties and overlays.
16895 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16897 * editfns.c (Fset_time_zone_rule): Document relationship with the
16900 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16901 the font entity extracted from the cache (Bug#8109).
16903 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16905 * composite.c (autocmp_chars): Don't reset point. That is done by
16906 restore_point_unwind (Bug#5984).
16908 2011-08-07 Juri Linkov <juri@jurta.org>
16910 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16911 to show the arg `TIME' instead of `TIMEVAL'.
16913 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16915 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16916 display property strides EOL and includes a newline, as in
16917 longlines-mode. (Bug#9254)
16918 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16919 word-wrap under bidirectional display. (Bug#9224)
16921 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16922 is non-zero, even if the data buffer is NULL. Fixes a crash in
16923 vertical-motion with longlines-mode. (Bug#9254)
16925 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16927 * bidi.c <bidi_cache_total_alloc>: Now static.
16928 (bidi_initialize): Initialize bidi_cache_total_alloc.
16930 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16933 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16934 amount allocated this far in `bidi_cache_total_alloc'.
16935 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16936 non-zero, only free the data buffer without restoring the cache
16937 contents. All callers changed.
16939 * dispextern.h (bidi_unshelve_cache): Update prototype.
16941 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16942 (move_it_in_display_line, move_it_to)
16943 (move_it_vertically_backward, move_it_by_lines): Replace the call
16944 to xfree to an equivalent call to bidi_unshelve_cache.
16945 (move_it_in_display_line_to): Fix logic of returning
16946 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16948 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16950 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16951 came from a string character with a `cursor' property. (Bug#9229)
16953 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16955 * Makefile.in (LIB_PTHREAD): New variable.
16956 (LIBES): Add LIB_PTHREAD (Bug#9216).
16958 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16959 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16961 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16963 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16965 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16967 * xterm.c (x_find_topmost_parent): New function.
16968 (x_set_frame_alpha): Find topmost parent window with
16969 x_find_topmost_parent and set the property there also (bug#9181).
16970 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16972 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16974 * callproc.c (Fcall_process): Avoid vfork clobbering
16975 the local vars buffer, coding_systems, current_dir.
16977 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16979 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16981 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16983 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16984 so that it is not optimized away.
16986 * xdisp.c (compute_display_string_pos): Remove unused local.
16988 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16990 Fix slow cursor motion and scrolling in large buffers with
16991 selective display, like Org Mode buffers. (Bug#9218)
16993 * dispextern.h (struct bidi_it): New member disp_prop_p.
16995 * xdisp.c: Remove one-slot cache of display string positions.
16996 (compute_display_string_pos): Accept an additional argument
16997 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16998 for a display string or property. If found, set DISP_PROP_P
17001 * bidi.c (bidi_fetch_char): Accept an additional argument
17002 DISP_PROP_P, and pass it to compute_display_string_pos.
17003 Only handle text covered by a display string if DISP_PROP_P is returned
17004 non-zero. All callers of bidi_fetch_char changed.
17006 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17008 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17010 2010-12-03 Don March <don@ohspite.net>
17012 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17013 last character M-[char] is translated to ESC [char] (bug#7541).
17015 2011-08-02 Kenichi Handa <handa@m17n.org>
17017 * lisp.h (uniprop_table): Extern it.
17019 * chartab.c (uniprop_table): Make it non-static.
17021 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17023 * xdisp.c (forward_to_next_line_start): Accept additional argument
17024 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17026 (reseat_at_next_visible_line_start): Use the bidi iterator state
17027 returned by forward_to_next_line_start to restore the state of
17028 it->bidi_it after backing up to previous newline. (Bug#9212)
17030 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17032 * regex.c (re_comp): Protoize.
17033 (re_exec): Fix return type.
17034 (regexec): Fix type of `ret'. (Bug#9203)
17036 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17038 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17039 This is needed if max-image-size is a floating-point number.
17041 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17043 * print.c (print_object): Print empty symbol as ##.
17045 * lread.c (read1): Read ## as empty symbol.
17047 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17049 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17050 setting frame foreground color (Bug#9175).
17051 (x_set_background_color): Likewise.
17053 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17054 contents (Bug#9176).
17055 (EmacsTooltip -init): Remove bezels and add shadows to
17058 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17059 or scroll bar (Bug#8470).
17061 * nsfont.m (nsfont_open): Remove assignment to voffset and
17062 unnecessary vars hshink, expand, hd, full_height, min_height.
17063 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17065 * nsterm.h (nsfont_info): Remove voffset field.
17067 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17069 Implement strike-through and overline on NextStep (Bug#8863).
17071 * nsfont.m (nsfont_open): Use underline position provided by font,
17072 instead of hard-coded value of 2.
17073 (nsfont_draw): Call ns_draw_text_decoration instead.
17075 * nsterm.h: Add declaration for ns_draw_text_decoration.
17077 * nsterm.m (ns_draw_text_decoration): New function for drawing
17078 underline, overline, and strike-through.
17079 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17080 ns_draw_text_decoration. Change treatment of cursor drawing to
17081 accommodate underlining, etc.
17083 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17085 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17088 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17090 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17091 Without this fix, if a signal arrives just after memory fills up,
17092 'malloc' might be invoked reentrantly.
17094 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17095 In other words, assume that every image size is allowed, on non-X
17096 hosts. This assumption is probably wrong, but it lets Emacs compile.
17098 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17100 * regex.c (re_iswctype): Convert return values to boolean.
17102 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17104 * xdisp.c (compute_display_string_pos): Don't use cached display
17105 string position if the buffer had its restriction changed.
17108 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17110 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17112 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17114 Integer signedness and overflow and related fixes. (Bug#9079)
17116 * bidi.c: Integer size and overflow fixes.
17117 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17118 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17119 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17120 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17121 (bidi_find_other_level_edge):
17122 Use ptrdiff_t instead of EMACS_INT where either will do.
17123 This works better on 32-bit hosts configured --with-wide-int.
17124 (bidi_cache_ensure_space): Check for size-calculation overflow.
17125 Use % rather than repeated addition, for better worst-case speed.
17126 Don't set bidi_cache_size until after xrealloc returns, because it
17128 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17129 (bidi_cache_ensure_space): Also check that the bidi cache size
17130 does not exceed that of the largest Lisp string or buffer. See Eli
17131 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17133 * alloc.c (__malloc_size_t): Remove.
17134 All uses replaced by size_t. See Andreas Schwab's note
17135 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17137 * image.c: Improve checking for integer overflow.
17138 (check_image_size): Assume that f is nonnull, since
17139 it is always nonnull in practice. This is one less thing to
17140 worry about when checking for integer overflow later.
17141 (x_check_image_size): New function, which checks for integer
17142 overflow issues inside X.
17143 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17144 This removes the need for a memory_full check.
17145 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17146 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17147 (xbm_read_bitmap_data): Change locals back to 'int', since
17148 their values must fit in 'int'.
17149 (xpm_load_image, png_load, tiff_load):
17150 Invoke x_create_x_image_and_pixmap earlier,
17151 to avoid much needless work if the image is too large.
17152 (tiff_load): Treat overly large images as if
17153 x_create_x_image_and_pixmap failed, not as malloc failures.
17154 (gs_load): Use x_check_image_size.
17156 * gtkutil.c: Omit integer casts.
17157 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17158 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17160 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17162 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17163 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17164 would wrongly return t on a 64-bit host.
17166 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17167 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17168 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17169 and therefore cause GCC to emit a bogus diagnostic in some cases.
17171 * image.c: Integer signedness and overflow and related fixes.
17172 This is not an exhaustive set of fixes, but it's time to
17173 record what I've got.
17174 (lookup_pixel_color, check_image_size): Remove redundant decls.
17175 (check_image_size): Don't assume that arbitrary EMACS_INT values
17176 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17177 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17178 (tiff_load, imagemagick_load_image):
17179 Check for overflow in size calculations.
17180 (x_create_x_image_and_pixmap): Remove unnecessary test for
17181 xmalloc returning NULL; that can't happen.
17182 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17183 (xpm_color_bucket): Use better integer hashing function.
17184 (xpm_cache_color): Don't possibly over-allocate memory.
17185 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17186 (gif_memory_source):
17187 Use ptrdiff_t, not int or size_t, to record sizes.
17188 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17189 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17190 either works, as we prefer signed integers.
17191 (tiff_read_from_memory, tiff_write_from_memory):
17192 Return tsize_t, not size_t, since that's what the TIFF API wants.
17193 (tiff_read_from_memory): Don't fail simply because the read would
17194 go past EOF; instead, return a short read.
17195 (tiff_load): Omit no-longer-needed casts.
17196 (Fimagemagick_types): Don't assume size fits into 'int'.
17198 Improve hashing quality when configured --with-wide-int.
17199 * fns.c (hash_string): New function, taken from sxhash_string.
17200 Do not discard information about ASCII character case; this
17201 discarding is no longer needed.
17202 (sxhash-string): Use it. Change sig to match it. Caller changed.
17203 * lisp.h: Declare it.
17204 * lread.c (hash_string): Remove, since we now use fns.c's version.
17205 The fns.c version returns a wider integer if --with-wide-int is
17206 specified, so this should help the quality of the hashing a bit.
17208 * emacs.c: Integer overflow minor fix.
17209 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17210 Define only if GNU_LINUX.
17211 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17213 * dispnew.c: Integer signedness and overflow fixes.
17214 Remove unnecessary forward decls, that were a maintenance hassle.
17215 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17217 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17218 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17219 (prepare_desired_row, line_draw_cost):
17220 Use int, not unsigned, where either works.
17221 (save_current_matrix, restore_current_matrix):
17222 Use ptrdiff_t, not size_t, where either works.
17223 (init_display): Check for overflow more accurately, and without
17224 relying on undefined behavior.
17226 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17227 Remove, replacing with the new symbols in lisp.h. All uses changed.
17228 * fileio.c (make_temp_name):
17229 * filelock.c (lock_file_1, lock_file):
17230 * xdisp.c (message_dolog):
17231 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17232 Use pMd etc. instead.
17233 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17234 replacing the pWIDE etc. symbols removed from editfns.c.
17236 * keyboard.h (num_input_events): Now uintmax_t.
17237 This is (very slightly) less likely to mess up due to wraparound.
17240 * buffer.c: Integer signedness fixes.
17241 (alloc_buffer_text, enlarge_buffer_text):
17242 Use ptrdiff_t rather than size_t when either will do, as we prefer
17245 * alloc.c: Integer signedness and overflow fixes.
17246 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17247 (__malloc_size_t): Default to size_t, not to int.
17248 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17249 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17250 Prefer ptrdiff_t to size_t when either would do, as we prefer
17252 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17253 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17254 Now const. Initialize with values that are in range even if char
17256 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17257 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17258 These functions do the right thing with sizes > 2**32.
17259 (check_depth): Now ptrdiff_t, not int.
17260 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17261 Adjust to new way of storing sizes. Check for size overflow bugs
17263 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17264 slightly wrong anyway, as it missed one instance of
17265 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17266 (refill_memory_reserve): Omit needless cast to size_t.
17267 (mark_object_loop_halt): Mark as externally visible.
17269 * xselect.c: Integer signedness and overflow fixes.
17270 (Fx_register_dnd_atom, x_handle_dnd_message):
17271 Use ptrdiff_t, not size_t, since we prefer signed.
17272 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17273 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17274 x_dnd_atoms_size and x_dnd_atoms_length.
17276 * doprnt.c: Prefer signed to unsigned when either works.
17278 * doprnt.c (doprnt):
17280 * xdisp.c (vmessage):
17281 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17282 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17283 prefer signed arithmetic to avoid comparison confusion.
17284 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17285 but is a bit tricky.
17287 Assume freestanding C89 headers, string.h, stdlib.h.
17288 * data.c, doprnt.c, floatfns.c, print.c:
17289 Include float.h unconditionally.
17290 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17291 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17292 * regex.c: Likewise for stddef.h, string.h.
17293 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17294 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17295 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17296 (STDC_HEADERS): Remove obsolete defines.
17297 * sysdep.c: Include limits.h unconditionally.
17299 Assume support for memcmp, memcpy, memmove, memset.
17300 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17301 * regex.c (memcmp, memcpy):
17302 Remove; we assume C89 now.
17304 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17305 (__malloc_safe_bcopy): Remove; no longer needed.
17307 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17308 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17309 well either way, and we prefer signed to unsigned.
17311 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17313 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17314 closes the connection while we're reading (bug#9182).
17316 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17318 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17319 are specified (Bug#9168).
17321 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17323 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17324 Found by GCC static checking and --with-wide-int on a 32-bit host.
17326 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17328 * xdisp.c (compute_display_string_pos): Fix logic of caching
17329 previous display string position. Initialize cached_prev_pos to
17330 -1. Fixes slow-down at the beginning of a buffer.
17332 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17334 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17335 for attrs[LFACE_FONTSET_INDEX].
17337 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17339 * xml.c (parse_region): Remove unused local
17340 that was recently introduced.
17342 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17344 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17345 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17347 * xdisp.c (move_it_in_display_line_to): Record the best matching
17348 position for TO_CHARPOS while scanning the line, and restore it on
17349 exit if none of the characters scanned was an exact match.
17350 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17351 when exact match is impossible due to invisible text, and the
17352 lines are truncated.
17354 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17356 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17359 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17361 Fix a significant slow-down of cursor motion with C-n, C-p,
17362 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17363 auto-repeat under bidi redisplay in fontified buffers.
17364 * xdisp.c (compute_stop_pos_backwards): New function.
17365 (next_element_from_buffer): Call compute_stop_pos_backwards to
17366 find a suitable prev_stop when we find ourselves before
17368 (reseat): Don't look for prev_stop, as that could mean a very long
17370 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17371 <cached_disp_overlay_modiff>: Cache for last found display string
17373 (compute_display_string_pos): Return the cached position if asked
17374 about the same buffer in the same area of character positions, and
17375 the buffer wasn't changed since the time the display string
17376 position was cached.
17378 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17380 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17381 is an integer, which is important for empty lines. (Bug#9149)
17383 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17385 * frame.c (Fmodify_frame_parameters): In tty case, update the
17386 default face if necessary (Bug#4238).
17388 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17390 * editfns.c (Fstring_to_char): No need to explain what a character
17391 is in the docstring (Bug#6576).
17393 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17395 * xml.c (parse_region): Make sure we always return a tree.
17397 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17399 * xml.c (parse_region): If a document contains only comments,
17402 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17404 * xml.c (make_dom): Return comments, too.
17406 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17409 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17410 and the surrounding thread.
17411 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17412 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17413 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17415 * s/openbsd.h (BROKEN_SIGIO): Define.
17416 * unexelf.c (unexec) [__OpenBSD__]:
17417 Don't update the .mdebug section of the Alpha COFF symbol table.
17419 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17421 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17424 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17426 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17427 This fixes some race conditions on the permissions of any newly
17430 * alloc.c (valid_pointer_p): Use pipe, not open.
17431 This fixes some permissions issues when debugging.
17433 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17434 If fchown fails to set both uid and gid, try to set just gid,
17435 as that is sometimes allowed. Adjust the file's mode to eliminate
17436 setuid or setgid bits that are inappropriate if fchown fails.
17438 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17440 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

17446 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17448 * lread.c (read_integer): Unread even EOF character.
17449 (read1): Likewise. Properly record start position of symbol.
17451 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17452 symbol character follows.
17454 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17456 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17457 This works around a problem with the previous change to Fcopy_file.
17458 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17459 and without this change, GCC might complain about discarding
17460 fchown's return value.
17462 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17464 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17466 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17468 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17470 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17472 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17473 it's used from the C level.
17475 * process.c: Use the same condition for POLL_FOR_INPUT in both
17476 keyboard.c and process.c (bug#1858).
17478 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17480 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17481 (Fgnutls_boot): Use it.
17483 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17485 * doc.c (Fsubstitute_command_keys): Revert last change.
17487 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17489 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17490 quotes the next character, and doesn't affect other longer
17491 sequences (bug#8935).
17493 * lread.c (syms_of_lread): Clarify that is isn't only
17494 `eval-buffer' and `eval-defun' that's affected by
17495 `lexical-binding' (bug#8460).
17497 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17499 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17500 bidi redisplay when a line includes both an image and is truncated.
17502 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17504 Fix minor problems found by static checking.
17505 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17506 (elsz): Now a signed constant, not a size_t var. We prefer signed
17507 types to unsigned, to avoid integer comparison confusion. Without
17508 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17509 "cannot optimize loop, the loop counter may overflow", a symptom
17511 * indent.c (Fvertical_motion): Mark locals as initialized.
17512 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17514 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17516 * search.c (Fre_search_backward): Mention `case-fold-search' in
17517 all the re_search_* functions (bug#8138).

17537 buffer position was specified. Initialize paragraph_embedding to
17539 (reseat_to_string): Initialize the bidi iterator.
17540 (display_string): If we need to ignore text properties of
17541 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17542 original value of -1 will not work with bidi.)
17543 (compute_display_string_pos): First arg is now struct
17544 `text_pos *'; all callers changed. Support display properties on
17546 (compute_display_string_end): Support display properties on Lisp
17548 (init_iterator, reseat_1, reseat_to_string): Initialize the
17549 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17550 when iterating on a string not from display properties).
17551 (compute_display_string_pos, compute_display_string_end):
17552 Fix calculation of the object to scan. Fixes an error when using
17554 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17555 base_level_stop; instead, set base_level_stop to BEGV.
17556 Fixes crashes in vertical-motion.
17557 (next_element_from_buffer): Improve commentary for when
17558 the iterator is before prev_stop.
17559 (init_iterator): Initialize bidi_p from the default value of
17560 bidi-display-reordering, not from buffer-local value. Use the
17561 buffer-local value only if initializing for buffer iteration.
17562 (handle_invisible_prop): Support invisible properties on strings
17563 that are being bidi-reordered.
17564 (set_iterator_to_next): Support bidi reordering of C strings and

17570 Use IT_STRING_CHARPOS when displaying from a Lisp string.
17571 (init_iterator): Don't initialize it->bidi_p for strings
17573 (reseat_to_string): Initialize it->bidi_p for strings here.

17580 character that is not the first one in the visual order.
17581 (get_visually_first_element): New function, refactored from common
17582 parts of next_element_from_buffer, next_element_from_string, and
17583 next_element_from_c_string.
17584 (tool_bar_lines_needed, redisplay_tool_bar)
17585 (display_menu_bar): Force left-to-right direction. Add a FIXME
17586 comment for making that be controlled by a user option.
17587 (push_it, pop_it): Save and restore the state of the
17588 bidi iterator. Save and restore the bidi_p flag.

17595 (get_overlay_strings_1, push_display_prop): Set up the bidi
17596 iterator for displaying display or overlay strings.
17597 (forward_to_next_line_start): Don't use the shortcut if
17599 (back_to_previous_visible_line_start): If handle_display_prop
17600 pushed the iterator stack, restore the internal state of the bidi
17601 iterator by calling bidi_pop_it same number of times.
17602 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17603 and we are bidi-iterating, don't decrement the iterator position;
17604 instead, set the first_elt flag in the bidi iterator, to produce
17606 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17607 (push_display_prop): xassert that we are iterating a buffer.
17608 (push_it, pop_it): Save and restore paragraph_embedding member.
17609 (handle_single_display_spec, next_overlay_string)
17610 (get_overlay_strings_1, reseat_1, reseat_to_string)
17611 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17612 correctly. Don't assume unibyte strings are not bidi-reordered.
17613 (compute_display_string_pos)
17614 (compute_display_string_end): Fix handling the case of C string.

17619 (pop_it): Call iterate_out_of_display_property only if we are
17620 popping after iteration over a string that came from a display
17621 property. Fix a typo in popping stretch info. Add an assertion
17622 for verifying that the iterator position is in sync with the bidi
17624 (handle_single_display_spec, get_overlay_strings_1)
17625 (push_display_prop): Fix initialization of paragraph direction for
17626 string when that of the parent object is not yet determined.

17632 Reset the from_disp_prop_p flag.
17633 (SAVE_IT, RESTORE_IT): New macros.

17638 (try_scrolling, redisplay_window, display_line): Use them when
17639 saving a temporary copy of the iterator and restoring it back.
17640 (back_to_previous_visible_line_start, reseat_1)
17641 (init_iterator): Empty the bidi cache "stack".
17642 (move_it_in_display_line_to): If iterator ended up at
17643 EOL, but we never saw any buffer positions smaller than
17644 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
17645 motion in bidi-reordered lines.

17649 displayed in margins. (Bug#8133) (Bug#8867)
17650 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
17652 (pos_visible_p): Support positions in bidi-reordered lines.
17653 Save and restore bidi cache.
17655 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
17656 (bidi_paragraph_info): Delete unused struct.

17674 Support iteration over a string.
17675 (bidi_set_sor_type, bidi_resolve_explicit_1)
17676 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
17677 can now be zero (for strings); special values 0 and -1 were
17678 changed to -1 and -2, respectively.
17679 (bidi_char_at_pos): New function.
17680 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

17691 (bidi_initialize): Initialize the bidi cache start stack pointer.
17692 (bidi_cache_ensure_space): New function, refactored from part of

17708 * dispextern.h (struct bidi_string_data): New structure.
17709 (struct bidi_it): New member `string'. Make flag members be 1-bit
17710 fields, and put them last in the struct.
17711 (compute_display_string_pos, compute_display_string_end):
17713 (bidi_push_it, bidi_pop_it): Add prototypes.
17714 (struct iterator_stack_entry): New members bidi_p,
17715 paragraph_embedding, and from_disp_prop_p.
17716 (struct it): Member bidi_p is now a bit field 1 bit wide.
17717 (bidi_shelve_cache, bidi_unshelve_cache):
17718 Declare prototypes.
17720 * .gdbinit (xvectype, xvector, xcompiled, xchartable, xboolvector)

17763 Pass Qx_lost_selection_functions rather than
17764 Vx_lost_selection_functions to Frun_hook_with_args.
17766 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
17768 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
17769 The old code sometimes used this field without initializing it.
17771 * alloc.c (gc_sweep): Don't read past end of array.
17772 In theory, the old code could also have corrupted Emacs internals,
17773 though it'd be very unlikely.
17775 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
17777 * character.c (Fcharacterp): Don't advertise optional ignored

18078 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18079 subseconds part to the entropy, as that's a bit more random.
18080 Prefer signed to unsigned, since the signedness doesn't matter and
18081 in general we prefer signed. When given a limit, use a
18082 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18083 latter isn't right if USE_2_TAGS_FOR_INTS.
18084 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18085 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18098 This is more efficient than Ffile_directory_p and avoids a minor race.

18102 * buffer.c (Foverlay_put): Say what the return value is

18128 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

18230 * eval.c (struct backtrace): Simplify and port the data structure.
18231 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18232 signed bit field, as this assumption is not portable and it makes
18233 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18234 "char debug_on_exit : 1" as this is not portable either; instead,
18235 use the portable "unsigned int debug_on_exit : 1". Remove unused
18236 member evalargs. Remove obsolete comments about cc bombing out.
18238 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18279 (sort_overlays, overlay_strings): When an overlay's clone number
18280 matches the window's clone number process the overlay even if
18281 the overlay's window property doesn't match the current window.
18283 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.

18306 (emacs_fixed_new): Set priv->f to argument.
18307 (emacs_fixed_get_preferred_width)
18308 (emacs_fixed_get_preferred_height): Use min_width/height from
18309 frames size_hint to set minimum and natural (Bug#8919).
18310 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
18311 and use min_width/height from frames size_hint to set
18312 min_width/height (Bug#8919).
18314 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.

18332 Use gnulib's dup2 module instead of rolling our own.
18333 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
18335 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18337 * dispnew.c (scrolling_window): Before scrolling, turn off a

18400 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
18402 Integer and buffer overflow fixes (Bug#8873).
18404 * print.c (printchar, strout): Check for string overflow.
18405 (PRINTPREPARE, printchar, strout):
18406 Don't set size unless allocation succeeds.
18408 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18409 for sizes. Check for string overflow more accurately.
18410 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
18412 * macros.c: Integer and buffer overflow fixes.
18413 * keyboard.h (struct keyboard.kbd_macro_bufsize):
18414 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
18415 Use ptrdiff_t, not int, for sizes.

18417 Check for size-calculation overflow.
18418 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
18420 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
18422 * lread.c: Integer overflow fixes.
18423 (read_integer): Radix is now EMACS_INT, not int,
18424 to improve quality of diagnostics for out-of-range radices.
18425 Calculate buffer size correctly for out-of-range radices.
18426 (read1): Check for integer overflow in radices, and in
18427 read-circle numbers.
18428 (read_escape): Avoid int overflow.
18429 (Fload, openp, read_buffer_size, read1)
18430 (substitute_object_recurse, read_vector, read_list, map_obarray):
18431 Use ptrdiff_t, not int, for sizes.
18432 (read1): Use EMACS_INT, not int, for sizes.
18433 Check for size overflow.
18435 * image.c (cache_image): Check for size arithmetic overflow.

18446 2011-06-22 Leo Liu <sdl.web@gmail.com>
18448 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
18449 Move to minibuffer.el.
18451 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18453 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18454 The following patches are for when GLYPH_DEBUG && !XASSERT.
18455 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18456 * dispnew.c (flush_stdout):
18457 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18458 Mark as externally visible.
18459 * dispnew.c (check_window_matrix_pointers): Now static.
18460 * dispnew.c (window_to_frame_vpos):
18461 * xfns.c (unwind_create_frame):
18462 * xterm.c (x_check_font): Remove unused local.
18463 * scroll.c (CHECK_BOUNDS):
18464 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18465 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18466 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18467 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18468 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18470 (debug_method_add): Use va_list and vsprintf rather than relying
18471 on undefined behavior with wrong number of arguments.
18472 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18473 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18474 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18475 since we're not interested in debugging glyphs with old libraries.
18476 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18477 GCC 4.6.0's static checking.
18479 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18481 Integer overflow and signedness fixes (Bug#8873).
18482 A few related buffer overrun fixes, too.

18492 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
18493 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
18495 * xfaces.c (load_pixmap):
18496 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
18497 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18498 (.bitmaps_last, struct x_output.icon_bitmap):
18499 Use ptrdiff_t, not int, for bitmap indexes.
18500 (x_allocate_bitmap_record): Check for size overflow.
18501 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18503 Use ptrdiff_t, not int, for overlay counts.
18504 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18505 * editfns.c (overlays_around, get_pos_property):
18506 * textprop.c (get_char_property_and_overlay):
18507 * xdisp.c (next_overlay_change, note_mouse_highlight):
18508 * xfaces.c (face_at_buffer_position):
18509 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18510 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18511 (Fnext_overlay_change, Fprevious_overlay_change)
18512 (mouse_face_overlay_overlaps, Foverlays_in):
18513 Use ptrdiff_t, not int, for sizes.
18514 (overlays_at, overlays_in): Check for size-calculation overflow.
18516 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18518 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18519 (x_session_initialize): Do not assume string length fits in int.
18521 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18522 This is unlikely, but can occur if DPI is outlandish.
18524 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18525 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18527 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18528 * xrdb.c (magic_file_p, search_magic_path):
18529 Omit last arg SUFFIX; it was always 0. All callers changed.
18530 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18532 * xfont.c (xfont_match): Avoid need for strlen.
18534 * xfns.c: Don't assume strlen fits in int.
18535 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18537 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18538 not unsigned long, as we prefer signed integers. All callers changed.
18539 Detect integer overflow in repeat count.
18540 (message_dolog): Don't assume print length fits in 39 bytes.
18541 (display_mode_element): Don't assume strlen fits in int.
18543 * termcap.c: Don't assume sizes fit in int and never overflow.
18544 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18545 (gobble_line): Check for size-calculation overflow.
18547 * minibuf.c (Fread_buffer):
18548 * lread.c (intern, intern_c_string):
18549 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18550 Don't assume string length fits in int.
18552 * keyboard.c (parse_tool_bar_item):
18553 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18555 * font.c: Don't assume string length fits in int.

18559 Don't assume integer property fits in fixnum.
18560 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18562 * filelock.c: Fix some buffer overrun and integer overflow issues.
18563 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18564 Reformulate so as not to need the command string.
18565 Invoke gzip -cd rather than gunzip, as it's more portable.
18566 (lock_info_type, lock_file_1, lock_file):
18567 Don't assume pid_t and time_t fit in unsigned long.
18568 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18569 (current_lock_owner): Prefer signed type for sizes.
18570 Use memcpy, not strncpy, where memcpy is what is really wanted.
18571 Don't assume (via atoi) that time_t and pid_t fit in int.
18572 Check for time_t and/or pid_t out of range, e.g., via a network share.
18573 Don't alloca where an auto var works fine.
18575 * fileio.c: Fix some integer overflow issues.
18576 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18577 Don't assume string length fits in int.
18578 (directory_file_name): Don't assume string length fits in long.
18579 (make_temp_name): Don't assume pid fits in int, or that its print
18580 length is less than 20.
18582 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18584 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18586 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18588 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18589 We prefer signed integers, even for size calculations.
18591 * emacs.c: Don't assume string length fits in 'int'.
18592 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18593 (main): Don't invoke strlen when not needed.

18598 * callproc.c (getenv_internal_1, getenv_internal)
18599 (Fgetenv_internal):
18600 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18602 * lread.c (invalid_syntax): Omit length argument.
18603 All uses changed. This doesn't fix a bug, but it simplifies the
18604 code away from its former Hollerith-constant appearance, and it's
18605 one less 'int' to worry about when looking at integer-overflow issues.
18606 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18608 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18609 This didn't break anything, but it didn't help either.
18610 It's confusing to put a bogus integer in a place where the actual
18611 value does not matter.
18612 (LIST_END_P): Remove unused macro and its bogus comment.
18613 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18615 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18616 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18618 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18619 We prefer signed types, and the value cannot exceed the EMACS_INT
18620 range anyway (because otherwise the length would not be representable).
18621 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18622 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18623 This avoids a GCC warning when WIDE_EMACS_INT.
18625 * indent.c (sane_tab_width): New function.
18626 (current_column, scan_for_column, Findent_to, position_indentation)
18627 (compute_motion): Use it. This is just for clarity.
18628 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18630 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18632 * lisp.h (lint_assume): New macro.
18633 * composite.c (composition_gstring_put_cache):
18634 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18636 * editfns.c, insdel.c:
18637 Omit unnecessary forward decls, to simplify future changes.
18639 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18641 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18643 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18644 Use much-faster test for byte-length change.
18645 Don't assume string byte-length fits in 'int'.
18646 Check that character arg fits in 'int'.
18647 (mapcar1): Declare byte as byte, for clarity.
18649 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18651 * fns.c (concat): Catch string overflow earlier.
18652 Do not rely on integer wraparound.
18654 * dispextern.h (struct it.overlay_strings_charpos)
18655 (struct it.selective): Now EMACS_INT, not int.
18656 * xdisp.c (forward_to_next_line_start)
18657 (back_to_previous_visible_line_start)
18658 (reseat_at_next_visible_line_start, next_element_from_buffer):
18659 Don't arbitrarily truncate the value of 'selective' to int.
18661 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18663 * composite.c: Don't truncate sizes to 'int'.
18664 (composition_gstring_p, composition_reseat_it)
18665 (composition_adjust_point): Use EMACS_INT, not int.
18666 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18667 not EMACS_UINT, for indexes.
18669 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18671 * buffer.c: Include <verify.h>.
18672 (struct sortvec.priority, struct sortstr.priority):
18673 Now EMACS_INT, not int.
18674 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18675 (struct sortstr.size, record_overlay_string)
18676 (struct sortstrlist.size, struct sortlist.used):
18677 Don't truncate size to int.
18678 (record_overlay_string): Check for size-calculation overflow.
18679 (init_buffer_once): Check at compile-time, not run-time.
18681 2011-06-22 Jim Meyering <meyering@redhat.com>
18683 Don't leak an XBM-image-sized buffer
18684 * image.c (xbm_load): Free the image buffer after using it.
18686 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18689 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18690 that Sun C diagnosed.
18691 * fns.c (secure_hash): Fix pointer signedness issue.
18692 * intervals.c (static_offset_intervals): New function.
18693 (offset_intervals): Use it.
18695 2011-06-21 Leo Liu <sdl.web@gmail.com>
18698 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18701 * fns.c (secure_hash): Rename from crypto_hash_function and change
18702 the first arg to accept symbols.
18703 (Fsecure_hash): New primitive.
18704 (syms_of_fns): New symbols.
18706 2011-06-20 Deniz Dogan <deniz@dogan.se>
18708 * process.c (Fset_process_buffer): Clarify return value in
18711 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18713 * dispnew.c (add_window_display_history): Use BVAR.
18715 * xdisp.c (debug_method_add): Use BVAR.
18716 (check_window_end, dump_glyph_matrix, dump_glyph)
18717 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18719 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18722 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18723 check till after the cache is created in init_frame_faces.
18725 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18727 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18729 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18731 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18732 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18733 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18735 Improve buffer-overflow checking (Bug#8873).
18736 * fileio.c (Finsert_file_contents):
18737 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18738 Remove the old (too-loose) buffer overflow checks.
18739 They weren't needed, since make_gap checks for buffer overflow.
18740 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18741 The old code merely checked for Emacs fixnum overflow, and relied
18742 on undefined (wraparound) behavior. The new code avoids undefined
18743 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18745 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18746 Tune. Don't use wider integers than needed. Don't use alloca.
18747 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18749 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18751 * insdel.c, lisp.h (buffer_overflow): New function.
18752 (insert_from_buffer_1, replace_range, replace_range_2):
18753 * insdel.c (make_gap_larger):
18754 * editfns.c (Finsert_char):
18755 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18757 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18759 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18761 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18763 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18764 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18766 * fileio.c: Don't assume EMACS_INT fits in off_t.
18767 (emacs_lseek): New static function.
18768 (Finsert_file_contents, Fwrite_region): Use it.
18769 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18771 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18773 * fns.c: Don't overflow int when computing a list length.
18774 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18775 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18776 truncation on 64-bit hosts. Check for QUIT every
18777 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18778 faster and is responsive enough.
18779 (Flength): Report an error instead of overflowing an integer.
18780 (Fsafe_length): Return a float if the value is not representable
18781 as a fixnum. This shouldn't happen except in contrived situations.
18782 (Fnthcdr, Fsort): Don't assume list length fits in int.
18783 (Fcopy_sequence): Don't assume vector length fits in int.
18785 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18786 (header_size, word_size): New constants.
18787 (allocate_vectorlike): Don't check size overflow here.
18788 (allocate_vector): Check it here instead, since this is the only
18789 caller of allocate_vectorlike that could cause overflow.
18790 Check that the new vector's length is representable as a fixnum.
18792 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18793 The previous code was bogus. For example, next_almost_prime (32)
18794 returned 39, which is undesirable as it is a multiple of 3; and
18795 next_almost_prime (24) returned 25, which is a multiple of 5 so
18796 why was the code bothering to check for multiples of 7?
18798 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18800 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18802 Variadic C functions now count arguments with ptrdiff_t.
18803 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18804 Back then I didn't know that the Emacs coding style prefers signed int.
18805 Also, in the meantime I found a few more instances where arguments
18806 were being counted with int, which may truncate counts on 64-bit
18807 machines, or EMACS_INT, which may be unnecessarily wide.
18808 * lisp.h (struct Lisp_Subr.function.aMANY)
18809 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18810 Arg counts are now ptrdiff_t, not size_t.
18811 All variadic functions and their callers changed accordingly.
18812 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18813 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18814 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18815 * callint.c (Fcall_interactively): Check arg count for overflow,
18816 to avoid potential buffer overrun. Use signed char, not 'int',
18817 for 'varies' array, so that we needn't bother to check its size
18818 calculation for overflow.
18819 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18820 * eval.c (apply_lambda):
18821 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18822 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18823 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18825 * callint.c (Fcall_interactively): Don't use index var as event count.
18827 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18828 * mem-limits.h (SIZE): Remove; no longer used.
18830 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18832 Remove unnecessary casts.
18833 * xterm.c (x_term_init):
18834 * xfns.c (x_set_border_pixel):
18835 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18836 These aren't needed now that we assume ANSI C.
18838 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18839 It's more likely to cause problems (due to unsigned overflow)
18842 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18844 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18846 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18848 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18850 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18852 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18854 GLYPH_CODE_FACE returns EMACS_INT, not int.
18855 * dispextern.h (merge_faces):
18856 * xfaces.c (merge_faces):
18857 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18858 Don't assume EMACS_INT fits in int.
18860 * character.h (CHAR_VALID_P): Remove unused parameter.
18861 * fontset.c, lisp.h, xdisp.c: All uses changed.
18863 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18865 * fns.c (concat): Minor tuning based on overflow analysis.
18866 This doesn't fix any bugs. Use int to hold character, instead
18867 of constantly refetching from Emacs object. Use XFASTINT, not
18868 XINT, for value known to be a character. Don't bother comparing
18869 a single byte to 0400, as it's always less.
18871 * floatfns.c (Fexpt):
18872 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18874 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18877 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18879 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18880 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18881 incorrectly succeed when S was a string, because 4294967386 was
18882 truncated before it was used.
18884 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18885 Otherwise, an out-of-range integer could cause undefined behavior
18888 * composite.c: Use int, not EMACS_INT, for characters.
18889 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18890 EMACS_INT, for values that are known to be in character range.
18891 This doesn't fix any bugs but is the usual style inside Emacs and
18892 may generate better code on 32-bit machines.
18894 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18895 This is for reasons similar to the recent CHAR_STRING fix.
18896 * charset.c (Fencode_char): Check that character arg is actually
18897 a character. Pass an int to ENCODE_CHAR.
18898 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18899 wider than 'int', as a compile-time check to prevent future regressions
18902 * character.c (char_string): Remove unnecessary casts.
18904 Make sure a 64-bit char is never passed to CHAR_STRING.
18905 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18906 by silently ignoring the top 32 bits, allowing some values
18907 that were far too large to be valid characters.
18908 * character.h: Include <verify.h>.
18909 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18910 arguments are no wider than unsigned, as a compile-time check
18911 to prevent future regressions in this area.
18913 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18914 (Fsubst_char_in_region):
18916 * xdisp.c (decode_mode_spec_coding):
18917 Adjust to CHAR_STRING's new requirement.
18918 * editfns.c (Finsert_char, Fsubst_char_in_region):
18919 * fns.c (concat): Check that character args are actually
18920 characters. Without this test, these functions did the wrong
18921 thing with wildly out-of-range values on 64-bit hosts.
18923 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18924 These casts should not be needed on 32-bit hosts, either.
18925 * keyboard.c (read_char):
18926 * lread.c (Fload): Remove casts to unsigned.
18928 * lisp.h (UNSIGNED_CMP): New macro.
18929 This fixes comparison bugs on 64-bit hosts.
18930 (ASCII_CHAR_P): Use it.
18931 * casefiddle.c (casify_object):
18932 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18933 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18934 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18935 * dispextern.h (FACE_FROM_ID):
18936 * keyboard.c (read_char): Use UNSIGNED_CMP.
18938 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18939 not to EMACS_INT, to avoid GCC warning.
18941 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18943 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18944 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18945 isn't needed on 32-bit machines.
18947 * buffer.c (Fgenerate_new_buffer_name):
18948 Use EMACS_INT for count, not int.
18949 (advance_to_char_boundary): Return EMACS_INT, not int.
18951 * data.c (Qcompiled_function): Now static.
18953 * window.c (window_body_lines): Now static.
18955 * image.c (gif_load): Rename local to avoid shadowing.
18957 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18958 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18959 * alloc.c (make_save_value): Integer argument is now of type
18960 ptrdiff_t, not int.
18961 (mark_object): Use ptrdiff_t, not int.
18962 * lisp.h (pD): New macro.
18963 * print.c (print_object): Use it.
18965 * alloc.c: Use EMACS_INT, not int, to count objects.
18966 (total_conses, total_markers, total_symbols, total_vector_size)
18967 (total_free_conses, total_free_markers, total_free_symbols)
18968 (total_free_floats, total_floats, total_free_intervals)
18969 (total_intervals, total_strings, total_free_strings):
18970 Now EMACS_INT, not int. All uses changed.
18971 (Fgarbage_collect): Compute overall total using a double, so that
18972 integer overflow is less likely to be a problem. Check for overflow
18973 when converting back to an integer.
18974 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18975 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18976 These were 'int' variables that could overflow on 64-bit hosts;
18977 they were never used, so remove them instead of repairing them.
18978 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18979 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18980 Previously, this ceilinged at INT_MAX, but that doesn't work on
18982 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18984 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18985 (allocate_vectorlike): Check for ptrdiff_t overflow.
18986 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18987 when a (possibly-narrower) signed value would do just as well.
18988 We prefer using signed arithmetic, to avoid comparison confusion.
18990 * alloc.c: Catch some string size overflows that we were missing.
18991 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18992 for convenience in STRING_BYTES_MAX.
18993 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18994 The definition here is exact; the one in lisp.h was approximate.
18995 (allocate_string_data): Check for string overflow. This catches
18996 some instances we weren't catching before. Also, it catches
18997 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18998 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18999 and ptrdiff_t and EMACS_INT are both 64 bits.
19001 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19002 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19003 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19005 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19007 * alloc.c (Fmake_string): Check for out-of-range init.
19009 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19011 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
19013 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
19015 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
19016 xg_get_default_scrollbar_width.
19018 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
19019 (int_gtk_range_get_value): Move to the scroll bar part of the file.
19020 (style_changed_cb): Call update_theme_scrollbar_width and call
19021 x_set_scroll_bar_default_width and xg_frame_set_char_size for
19022 all frames (Bug#8505).
19023 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
19024 Call gtk_window_set_resizable if HAVE_GTK3.
19025 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
19026 and height if HAVE_GTK3 (Bug#8505).
19027 (scroll_bar_width_for_theme): New variable.
19028 (update_theme_scrollbar_width): New function.
19029 (xg_get_default_scrollbar_width): Move code to
19030 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
19031 (xg_initialize): Call update_theme_scrollbar_width.
19033 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
19035 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
19037 2011-06-12 Martin Rudalics <rudalics@gmx.at>
19039 * frame.c (make_frame): Call other_buffer_safely instead of
19042 * window.c (temp_output_buffer_show): Call display_buffer with
19043 second argument Vtemp_buffer_show_specifiers and reset latter
19044 immediately after the call.
19045 (Vtemp_buffer_show_specifiers): New variable.
19046 (auto_window_vscroll_p, next_screen_context_lines)
19047 (Vscroll_preserve_screen_position): Remove leading asterisks from
19050 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
19052 Fix minor problems found by GCC 4.6.0 static checking.
19053 * buffer.c (Qclone_number): Remove for now, as it's unused.
19054 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
19055 (record_buffer): Remove unused local.
19056 * frame.c (other_visible_frames, frame_buffer_list): Now static.
19057 (set_frame_buffer_list): Remove; unused.
19058 * frame.h (other_visible_frames): Remove decl.
19059 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
19060 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
19061 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
19063 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
19064 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
19065 Define only if HAVE_GPM.
19066 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
19067 (update_hints_inhibit): Remove; never set. All uses removed.
19068 * widgetprv.h (emacsFrameClassRec): Remove decl.
19069 * window.c (delete_deletable_window): Now returns void, since it
19070 wasn't returning anything.
19071 (compare_window_configurations): Remove unused locals.
19072 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
19073 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
19074 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
19075 the same widths as pointers. This follows up on the 2011-05-06 patch.
19076 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
19077 * xterm.h: Likewise.
19078 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
19080 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
19082 * makefile.w32-in: Update dependencies.
19083 (LISP_H): Add lib/intprops.h.
19085 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
19087 * image.c (gif_load): Add animation frame delay to the metadata.
19088 (syms_of_image): Use DEFSYM. New symbol `delay'.
19090 2011-06-11 Martin Rudalics <rudalics@gmx.at>
19092 * window.c (delete_deletable_window): Re-add.
19093 (Fset_window_configuration): Rewrite to handle dead buffers and
19094 consequently deletable windows.
19095 (window_tree, Fwindow_tree): Remove. Supply functionality in

19550 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
19552 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19554 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
19555 in the current matrix if keep_current_p is non-zero.
19557 2011-06-04 Eli Zaretskii <eliz@gnu.org>
19559 * bidi.c (bidi_level_of_next_char): Fix last change.
19561 2011-06-03 Eli Zaretskii <eliz@gnu.org>
19563 Support bidi reordering of text covered by display properties.
19565 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
19566 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
19567 (bidi_cache_search, bidi_cache_iterator_state)
19568 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
19569 (bidi_level_of_next_char, bidi_move_to_visually_next):
19570 Support character positions inside a run of characters covered by a
19572 (bidi_paragraph_init, bidi_resolve_explicit_1)
19573 (bidi_level_of_next_char): Call bidi_fetch_char and
19574 bidi_fetch_char_advance instead of FETCH_CHAR and
19575 FETCH_CHAR_ADVANCE.
19576 (bidi_init_it): Initialize new members.
19577 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
19579 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
19580 instead of using explicit *_CHAR codes.
19581 (bidi_resolve_explicit, bidi_resolve_weak):
19582 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
19583 bidirectional text is supported only in multibyte buffers.
19584 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
19585 it to initialize the frame_window_p member of struct bidi_it.
19586 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
19587 (bidi_resolve_explicit, bidi_resolve_weak)
19588 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
19589 bidi_it->nchars is non-positive.
19590 (bidi_level_of_next_char): Don't try to lookup the cache for the
19591 next/previous character if nothing is cached there yet, or if we
19592 were just reseat()'ed to a new position.
19594 * xdisp.c (set_cursor_from_row): Set start and stop points
19595 according to the row's direction when priming the loop that looks
19596 for the glyph on which to display cursor.
19597 (single_display_spec_intangible_p): Function deleted.
19598 (display_prop_intangible_p): Reimplement to call
19599 handle_display_spec instead of single_display_spec_intangible_p.
19600 Accept 3 additional arguments needed by handle_display_spec.
19601 This fixes incorrect cursor motion across display property with complex
19602 values: lists, `(when COND...)' forms, etc.
19603 (single_display_spec_string_p): Support property values that are
19604 lists with the argument STRING its top-level element.
19605 (display_prop_string_p): Fix the condition for processing a
19606 property that is a list to be consistent with handle_display_spec.
19607 (handle_display_spec): New function, refactored from the
19608 last portion of handle_display_prop.
19609 (compute_display_string_pos): Accept additional argument
19610 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19611 value of a `display' property is a "replacing spec".
19612 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19613 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19614 the display property, but just return a value indicating whether
19615 the display property will replace the characters it covers.
19616 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19617 frame_window_p members of struct bidi_it.
19618 (compute_display_string_pos, compute_display_string_end):
19620 (push_it): Accept second argument POSITION, where pop_it should
19621 jump to continue iteration.
19622 (reseat_1): Initialize bidi_it.disp_pos.
19624 * keyboard.c (adjust_point_for_property): Adjust the call to
19625 display_prop_intangible_p to its new signature.
19627 * dispextern.h (struct bidi_it): New member frame_window_p.
19628 (bidi_init_it): Update prototypes.
19629 (display_prop_intangible_p): Update prototype.
19630 (compute_display_string_pos, compute_display_string_end):
19631 Declare prototypes.
19632 (struct bidi_it): New members nchars and disp_pos. ch_len is now
19635 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
19637 Malloc failure behavior now depends on size of allocation.
19638 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19639 * lisp.h: Change signatures accordingly.
19640 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19641 All callers changed. (Bug#8762)
19643 * gnutls.c: Use Emacs's memory allocators.
19644 Without this change, the gnutls library would invoke malloc etc.
19645 directly, which causes problems on non-SYNC_INPUT hosts, and which
19646 runs afoul of improving memory_full behavior. (Bug#8761)
19647 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19648 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19649 xfree instead of the default malloc, realloc, free.
19650 (Fgnutls_boot): No need to check for memory allocation failure,
19651 since xmalloc does that for us.
19653 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19654 * category.c (hash_get_category_set):
19655 * ccl.c (ccl_driver):
19656 * charset.c (Fdefine_charset_internal):
19657 * charset.h (struct charset.hash_index):
19658 * composite.c (get_composition_id, gstring_lookup_cache)
19659 (composition_gstring_put_cache):
19660 * composite.h (struct composition.hash_index):
19661 * dispextern.h (struct image.hash):
19662 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
19663 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
19664 (hashfn_equal, hashfn_user_defined, make_hash_table)
19665 (maybe_resize_hash_table, hash_lookup, hash_put)
19666 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
19667 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
19668 (Fsxhash, Fgethash, Fputhash, Fmaphash):
19669 * image.c (make_image, search_image_cache, lookup_image)
19670 (xpm_put_color_table_h):
19671 * lisp.h (struct Lisp_Hash_Table):
19672 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19673 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19674 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19675 * alloc.c (allocate_vectorlike):
19676 Check for overflow in vector size calculations.
19677 * ccl.c (ccl_driver):
19678 Check for overflow when converting EMACS_INT to int.
19679 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19680 need to be updated by these changes.
19681 * fns.c (make_hash_table, maybe_resize_hash_table):
19682 Check for integer overflow with large hash tables.
19683 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19684 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19685 (SXHASH_REDUCE): New macro.
19686 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19687 Use it instead of discarding useful hash info with large hash values.
19688 (sxhash_float): New function.
19689 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19690 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19691 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19692 Rewrite to use FIXNUM_BITS, as this simplifies things.
19693 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19694 Adjust signatures to match updated version of code.
19695 (consing_since_gc): Now EMACS_INT, since a single hash table can
19696 use more than INT_MAX bytes.
19698 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19700 Make it possible to build with GCC-4.6+ -O2 -flto.
19702 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19704 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19706 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19707 Call minibuffer-inactive-mode.
19709 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19711 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19712 Update dependencies.
19714 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19716 * data.c (init_data): Remove code for UTS, this system is not
19719 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19721 Don't force ./temacs to start in terminal mode.
19723 * frame.c (make_initial_frame): Initialize faces in all cases, not
19724 only when CANNOT_DUMP is defined.
19725 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19727 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19729 * dispnew.c (add_window_display_history): Use const for the string
19730 pointer. Remove declaration, not needed.
19732 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19734 Use 'inline', not 'INLINE'.
19735 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19736 * alloc.c, fontset.c (INLINE): Remove.
19737 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19738 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19739 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19740 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19741 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19743 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19745 Make it possible to run ./temacs.
19747 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19748 syms_of_callproc does the same thing. Remove test for
19749 "initialized", do it in the caller.
19750 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19752 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19754 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19755 (read_minibuf): Use get_minibuffer.
19756 (syms_of_minibuf): Use DEFSYM.
19757 (Qmetadata): New var.
19758 * data.c (Qbuffer): Don't make it static.
19759 (syms_of_data): Use DEFSYM.
19761 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19763 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19764 (CCL_CODE_MIN): New macro.
19766 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19768 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19770 * eval.c (Qdebug): Now static.
19771 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19772 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19773 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19775 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19777 * image.c: Various fixes to ImageMagick code comments.
19778 (Fimagemagick_types): Doc fix.
19780 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19782 Minor fixes prompted by GCC 4.6.0 warnings.
19784 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19786 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19787 (x_clipboard_manager_save_all): Move extern decl to ...
19788 * xterm.h: ... here, so that it can be checked for consistency.
19790 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19792 * xselect.c (x_clipboard_manager_save_frame)
19793 (x_clipboard_manager_save_all): New functions.
19794 (Fx_clipboard_manager_save): Lisp function deleted.
19796 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19797 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19799 * xterm.h: Update prototype.
19801 2011-05-28 William Xu <william.xwl@gmail.com>
19803 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19804 exiting (Bug#8239).
19806 2011-05-28 Jim Meyering <meyering@redhat.com>
19808 Avoid a sign-extension bug in crypto_hash_function.
19809 * fns.c (to_uchar): Define.
19810 (crypto_hash_function): Use it to convert some newly-signed
19811 variables to unsigned, to avoid sign-extension bugs. For example,
19812 without this change, (md5 "truc") would evaluate to
19813 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19814 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19815 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19817 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19819 Integer overflow fixes.
19821 * dbusbind.c: Serial number integer overflow fixes.
19822 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19823 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19824 to hold a serial number that is too large for a fixnum.
19825 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19826 Check for serial numbers out of range. Decode any serial number
19827 that was so large that it became a float. (Bug#8722)
19829 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19830 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19831 Use XFASTINT rather than XUINT when numbers are nonnegative.
19832 (xd_append_arg, Fdbus_method_return_internal):
19833 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19834 arguments, check that Lisp number is nonnegative, rather than
19835 silently wrapping negative numbers around. (Bug#8722)
19836 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19839 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19841 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19843 ccl: Add integer overflow checks.
19844 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19845 (IN_INT_RANGE): New macros.
19846 (ccl_driver): Use them to check for integer overflow when
19847 decoding a CCL program. Many of the new checks are whether XINT (x)
19848 fits in int; it doesn't always, on 64-bit hosts. The new version
19849 doesn't catch all possible integer overflows, but it's an
19850 improvement. (Bug#8719)
19852 * alloc.c (make_event_array): Use XINT, not XUINT.
19853 There's no need for unsigned here.
19855 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19856 This follows up to the 2011-05-06 change that substituted uintptr_t
19857 for EMACS_INT. This case wasn't caught back then.
19859 Rework Fformat to avoid integer overflow issues.
19860 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19861 now (part of C89). Include <verify.h>.
19862 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19863 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19864 (Fformat): Avoid the prepass trying to compute sizes; it was only
19865 approximate and thus did not catch overflow reliably. Instead, walk
19866 through the format just once, formatting and computing sizes as we go,
19867 checking for integer overflow at every step, and allocating a larger
19868 buffer as needed. Keep track separately whether the format is
19869 multibyte. Keep only the most-recently calculated precision, rather
19870 than them all. Record whether each argument has been converted to
19871 string. Use EMACS_INT, not int, for byte and char and arg counts.
19872 Support field widths and precisions larger than INT_MAX. Avoid
19873 sprintf's undefined behavior with conversion specifications such as %#d
19874 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19875 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19876 formatting out-of-range floating point numbers with int
19877 formats. (Bug#8668)
19879 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19881 * data.c: Avoid integer truncation in expressions involving floats.
19882 * data.c: Include <intprops.h>.
19883 (arith_driver): When there's an integer overflow in an expression
19884 involving floating point, convert the integers to floating point
19885 so that the resulting value does not suffer from catastrophic
19886 integer truncation. For example, on a 64-bit host (* 4
19887 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19888 Do not rely on undefined behavior after integer overflow.
19890 merge count_size_as_multibyte, parse_str_to_multibyte
19891 * character.c, character.h (count_size_as_multibyte):
19892 Rename from parse_str_to_multibyte; all uses changed.
19893 Check for integer overflow.
19894 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19895 since it's now a duplicate of the other. This is more of
19896 a character than a buffer op, so better that it's in character.c.
19897 * fns.c, print.c: Adjust to above changes.
19899 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19901 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19903 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19905 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19906 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19907 (x_clipboard_manager_save): Now static.
19908 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19910 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19911 (crypto_hash_function): Now static.
19912 Fix pointer signedness problems. Avoid unnecessary initializations.
19914 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19916 * termhooks.h (Vselection_alist): Make it terminal-local.
19918 * terminal.c (create_terminal): Initialize it.
19920 * xselect.c: Support for clipboard managers.
19921 (Vselection_alist): Move to termhooks.h as terminal-local var.
19922 (LOCAL_SELECTION): New macro.
19923 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19924 (symbol_to_x_atom): Remove gratuitous arg.
19925 (x_handle_selection_request, lisp_data_to_selection_data)
19926 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19927 (x_own_selection, x_get_local_selection, x_convert_selection):
19928 New arg, specifying work frame. Use terminal-local Vselection_alist.
19929 (some_frame_on_display): Delete unused function.
19930 (Fx_own_selection_internal, Fx_get_selection_internal)
19931 (Fx_disown_selection_internal, Fx_selection_owner_p)
19932 (Fx_selection_exists_p): New optional frame arg.
19933 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19934 (x_handle_selection_clear): Don't treat other terminals with the
19935 same keyboard specially. Use the terminal-local Vselection_alist.
19936 (x_clear_frame_selections): Use Frun_hook_with_args.
19938 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19940 * xterm.h: Add support for those atoms.
19942 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19944 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19945 (converted_selections, conversion_fail_tag): New global variables.
19946 (x_selection_request_lisp_error): Free the above.
19947 (x_get_local_selection): Remove unnecessary code.
19948 (x_reply_selection_request): Args changed; handle arbitrary array
19949 of converted selections stored in converted_selections.
19950 Separate the XChangeProperty and SelectionNotify steps.
19951 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19952 (x_convert_selection): New function.
19953 (x_handle_selection_event): Simplify.
19954 (x_get_foreign_selection): Don't ignore incoming requests while
19955 waiting for an answer; this will fail when we implement
19956 SAVE_TARGETS, and seems unnecessary anyway.
19957 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19958 (Vx_sent_selection_functions): Doc fix.
19960 2011-05-26 Leo Liu <sdl.web@gmail.com>
19962 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19964 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19966 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19968 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19969 for fringe update if it has periodic bitmap.
19970 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19971 and fringe_bitmap_periodic_p.
19973 * fringe.c (get_fringe_bitmap_data): New function.
19974 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19975 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19976 row. Mark glyph row for fringe update if periodicity changed.
19978 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19979 for fringe update unless it has periodic bitmap.
19981 2011-05-25 Kenichi Handa <handa@m17n.org>
19983 * xdisp.c (get_next_display_element): Set correct it->face_id for
19984 a static composition.
19986 2011-05-24 Leo Liu <sdl.web@gmail.com>
19989 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19991 * fns.c (crypto_hash_function, Fsha1): New function.
19992 (Fmd5): Use crypto_hash_function.
19993 (syms_of_fns): Add Ssha1.
19995 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19997 * gnutls.c: Remove unused macros.
19998 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19999 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20000 Remove macros that are defined and never used.
20001 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20003 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20005 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20006 (Fx_get_selection_internal): Minor cleanup.
20007 (Fx_own_selection_internal): Rename arguments for consistency with
20010 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20012 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20014 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20016 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20018 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20020 * dispnew.c (scrolling_window): Don't exclude the case that the
20021 last enabled row in the desired matrix touches the bottom boundary.
20023 2011-05-21 Glenn Morris <rgm@gnu.org>
20025 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20026 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20027 and add some more files.
20029 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20031 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20032 report_file_error introduced by the change from 2011-05-07.
20034 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20036 * systime.h (Time): Define only if emacs is defined.
20037 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20038 where the include path doesn't have X11/X.h by default. See
20039 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20041 2011-05-20 Kenichi Handa <handa@m17n.org>
20043 * composite.c (find_automatic_composition): Fix previous change.
20045 2011-05-20 Glenn Morris <rgm@gnu.org>
20047 * lisp.mk: New file, split from Makefile.in.
20048 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20049 (shortlisp): Remove.
20050 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20052 2011-05-19 Glenn Morris <rgm@gnu.org>
20054 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20055 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20056 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20057 (lisp): Set the order to that of loadup.el.
20058 (shortlisp): Make it a copy of $lisp.
20059 (SOME_MACHINE_LISP): Remove.
20060 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20061 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20063 2011-05-18 Kenichi Handa <handa@m17n.org>
20065 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20066 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20067 (find_automatic_composition): Mostly rewrite for efficiency.
20069 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20071 * makefile.w32-in: Update dependencies.
20073 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20075 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20076 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20078 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20080 Fix some integer overflow issues, such as string length overflow.
20082 * insdel.c (count_size_as_multibyte): Check for string overflow.
20084 * character.c (lisp_string_width): Check for string overflow.
20085 Use EMACS_INT, not int, for string indexes and lengths; in
20086 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20087 the resulting string length overflows an EMACS_INT; instead,
20088 report a string overflow if no precision given. When checking for
20089 precision exhaustion, use a check that cannot possibly have
20090 integer overflow. (Bug#8675)
20091 * character.h (lisp_string_width): Adjust to new signature.
20093 * alloc.c (string_overflow): New function.
20094 (Fmake_string): Use it. This doesn't change behavior, but saves
20095 a few bytes and will simplify future changes.
20096 * character.c (string_escape_byte8): Likewise.
20097 * lisp.h (string_overflow): New decl.
20099 Fixups, following up to the user-interface timestamp change.
20100 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20101 for UI timestamps, instead of unsigned long.
20102 * msdos.c (mouse_get_pos): Likewise.
20103 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20104 * w32gui.h (Time): Define by including "systime.h" rather than by
20105 declaring it ourselves. (Bug#8664)
20107 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20108 * image.c (clear_image_cache): Likewise.
20110 * term.c (term_mouse_position): Don't assume time_t wraparound.
20112 Be more systematic about user-interface timestamps.
20113 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20114 and sometimes 'EMACS_UINT', to represent these timestamps.
20115 This change causes it to use 'Time' uniformly, as that's what X uses.
20116 This makes the code easier to follow, and makes it easier to catch
20117 integer overflow bugs such as Bug#8664.
20118 * frame.c (Fmouse_position, Fmouse_pixel_position):
20119 Use Time, not unsigned long, for user-interface timestamps.
20120 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20121 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20122 * keyboard.h (last_event_timestamp): Likewise.
20123 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20124 * menu.h (xmenu_show): Likewise.
20125 * term.c (term_mouse_position): Likewise.
20126 * termhooks.h (struct input_event.timestamp): Likewise.
20127 (struct terminal.mouse_position_hook): Likewise.
20128 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20129 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20130 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20131 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20132 what it was before.
20133 * menu.h, termhooks.h: Include "systime.h", for Time.
20135 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20136 Don't assume that the difference between two unsigned long values
20137 can fit into an integer. At this point, we know button_down_time
20138 <= event->timestamp, so the difference must be nonnegative, so
20139 there's no need to cast the result if double-click-time is
20140 nonnegative, as it should be; check that it's nonnegative, just in
20141 case. This bug is triggered when events are more than 2**31 ms
20142 apart (about 25 days). (Bug#8664)
20144 * xselect.c (last_event_timestamp): Remove duplicate decl.
20145 (x_own_selection): Remove needless cast to unsigned long.
20147 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20148 that always fit in int. Use a sentinel instead of a counter, to
20149 avoid a temp and to allay GCC's concerns about possible int overflow.
20150 * frame.h (struct frame): Use int for menu_bar_items_used
20151 instead of EMACS_INT, since it always fits in int.
20153 * menu.c (grow_menu_items): Check for int overflow.
20155 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20157 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20158 Before, the code was not consistent. These values cannot exceed
20159 2**31 - 1 so there's no need to make them unsigned.
20160 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20161 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20162 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20164 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20166 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20167 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20168 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20169 presumably because the widths might not match.
20171 * window.c (size_window): Avoid needless test at loop start.
20173 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20175 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20177 2011-05-12 Drew Adams <drew.adams@oracle.com>
20179 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20181 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20183 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20184 `width' to `bar_area_x' and `bar_area_width', respectively.
20185 (x_scroll_run): Take account of fringe background extension.
20187 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20188 Rename local vars `left' and `width' to `bar_area_x' and
20189 `bar_area_width', respectively.
20190 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20191 background extension.
20193 2011-05-10 Jim Meyering <meyering@redhat.com>
20195 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20197 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20199 * image.c (Finit_image_library): Return t for built-in image types,
20200 like pbm and xbm. (Bug#8640)
20202 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20204 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20206 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20208 * w32console.c (Fset_screen_color): Doc fix.
20209 (Fget_screen_color): New function.
20210 (syms_of_ntterm): Defsubr it.
20212 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20213 unlink the temporary file if Fcall_process didn't create it in the
20215 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20216 child process will be redirected to a file specified with `:file'.
20217 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20218 cue to call_process_cleanup not to close that handle.
20220 2011-05-07 Ben Key <bkey76@gmail.com>
20222 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20223 one of two shell specific rules, either bootstrap-temacs-CMD or
20224 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20225 to the previous implementation of the bootstrap-temacs rule.
20226 The bootstrap-temacs-CMD rule is similar to the previous
20227 implementation of the bootstrap-temacs rule except that it
20228 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20231 These changes, along with some changes to nt/configure.bat,
20232 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20233 earlier fix to add support for --cflags and --ldflags options
20234 that include quotes so that it works whether make uses cmd or
20237 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20239 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20240 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20242 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20243 a string. Handle both cases.
20244 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20245 (Fdbus_register_method): Use Qinvalid_function.
20247 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20249 * makefile.w32-in: Update dependencies.
20250 (LISP_H): Add inttypes.h and stdin.h.
20251 (PROCESS_H): Add unistd.h.
20253 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20255 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20256 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20258 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20260 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20262 * term.c (vfatal): Remove stray call to va_end.
20263 It's not needed and the C Standard doesn't allow it here anyway.
20265 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20266 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20268 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20271 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20273 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20275 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20277 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20279 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20281 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20282 * charset.c (Fdefine_charset_internal): Don't initialize
20283 charset.code_space[15]. The value was garbage, on hosts with
20284 32-bit int (Bug#8600).
20286 * lread.c (read_integer): Be more consistent with string-to-number.
20287 Use string_to_number to do the actual conversion; this avoids
20288 rounding errors and fixes some other screwups. Without this fix,
20289 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20290 (digit_to_number): Move earlier, for benefit of read_integer.
20291 Return -1 if the digit is out of range for the base, -2 if it is
20292 not a digit in any supported base. (Bug#8602)
20294 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20296 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20297 to match comment at start of function. This also removes a
20298 GCC warning about overflow in a 32+64-bit port.
20300 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20302 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20303 Reported by Stefan Monnier in
20304 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20305 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20306 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20308 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20309 (EMACS_UINTPTR): Likewise, with uintptr_t.
20311 * lisp.h: Prefer 64-bit EMACS_INT if available.
20312 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20313 on 32-bit hosts that have 64-bit int, so that they can access
20315 However, temporarily disable this change unless the temporary
20316 symbol WIDE_EMACS_INT is defined.
20318 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20320 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20321 This removes an assumption that EMACS_INT and long are the same
20322 width as pointers. The assumption is true for Emacs porting targets
20323 now, but we want to make other targets possible.
20324 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20325 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20326 In the rest of the code, change types of integers that hold casted
20327 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20328 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20329 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20330 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20331 No need to cast type when ORing.
20332 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20333 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20334 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20335 assume EMACS_INT is the same width as char *.
20336 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20337 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20338 Remove no-longer-needed casts.
20339 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20340 (xg_tool_bar_help_callback, xg_make_tool_item):
20341 Use EMACS_INTPTR to hold an integer
20342 that will be cast to void *; this can avoid a GCC warning
20343 if EMACS_INT is not the same width as void *.
20344 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20345 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20346 (current_message_1, set_message_1):
20347 Use a local to convert to proper width without a cast.
20348 * xmenu.c (dialog_selection_callback): Likewise.
20350 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20351 Also, don't assume VALBITS / RAND_BITS is less than 5,
20352 and don't rely on undefined behavior when shifting a 1 left into
20354 * lisp.h (get_random): Change signature to match.
20356 * lread.c (hash_string): Use size_t, not int, for hash computation.
20357 Normally we prefer signed values; but hashing is special, because
20358 it's better to use unsigned division on hash table sizes so that
20359 the remainder is nonnegative. Also, size_t is the natural width
20360 for hashing into memory. The previous code used 'int', which doesn't
20361 retain enough info to hash well into very large tables.
20362 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20364 * dbusbind.c: Don't possibly lose pointer info when converting.
20365 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20366 Use XPNTR rather than XHASH, so that the high-order bits of
20367 the pointer aren't lost when converting through void *.
20369 * eval.c (Fautoload): Don't double-shift a pointer.
20371 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20373 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20375 * gnutls.c (DEF_GNUTLS_FN):
20376 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20378 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20380 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20383 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20385 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20386 New version that can reserve upto 2GB of heap space.
20388 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20390 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20392 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20394 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20395 `gnutls_certificate_set_x509_key_file'.
20397 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20399 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20400 Update dependencies.

20454 * process.c: Include lisp.h before w32.h, not after.
20455 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20456 instead of gnutls_record_check_pending.

20508 rather than `XVECTOR (FOO)->size'.
20510 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20511 inttypes.h, as a gnulib replacement is used if it not available in

20533 %llo or %llx format is passed. (Bug#8545)
20535 * window.c (window_scroll_line_based): Use a marker instead of
20536 simple variables to record original value of point. (Bug#7952)

20539 produced by %s or %c overflows available buffer space. (Bug#8545)
20541 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20543 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

20546 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20548 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20550 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20552 * keyboard.c (Qdelayed_warnings_hook): Define.
20553 (command_loop_1): Run `delayed-warnings-hook'
20554 if Vdelayed_warnings_list is non-nil.
20555 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20556 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20558 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20560 * doprnt.c (doprnt): Don't return value smaller than the buffer
20561 size if the message was truncated. (Bug#8545).
20563 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20565 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20566 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20568 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20570 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20572 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20574 * makefile.w32-in: Update dependencies.
20576 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20578 Improve `doprnt' and its usage. (Bug#8545)
20579 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20580 `format_end'. Remove support for %l as a conversion specifier.
20581 Don't use xrealloc. Improve diagnostics when the %l size modifier
20582 is used. Update the commentary.
20584 * eval.c (verror): Simplify calculation of size_t.
20586 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20589 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20591 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20594 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20596 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20597 This makes this file independent of the recent pseudovector change.
20599 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20601 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20603 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20604 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20605 Remove unused local.
20606 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20608 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20609 GCC 4.6.0 optimizes based on type-based alias analysis.
20610 For example, if b is of type struct buffer * and v of type struct
20611 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20612 != &v->size, and therefore "v->size = 1; b->size = 2; return
20613 v->size;" must therefore return 1. This assumption is incorrect
20614 for Emacs, since it type-puns struct Lisp_Vector * with many other
20615 types. To fix this problem, this patch adds a new type struct
20616 vectorlike_header that documents the constraints on layout of vectors
20617 and pseudovectors, and helps optimizing compilers not get fooled
20618 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20619 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20620 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20622 (XSETPVECTYPE): Rewrite in terms of new macro.
20623 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20624 This is a bit clearer, and further avoids the possibility of
20625 undesirable aliasing.
20626 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20627 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20628 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20629 since Lisp_Subr is a special case (no "next" field).
20630 (ASIZE): Now uses header.size rather than size.
20631 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20632 to avoid the hassle of writing XVECTOR (foo)->header.size.
20633 (struct vectorlike_header): New type.
20634 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20635 object, to help avoid aliasing.
20636 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20637 (SUBRP): Likewise, since Lisp_Subr is a special case.
20638 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20639 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20640 (struct Lisp_Hash_Table): Combine first two members into a single
20641 struct vectorlike_header member. All uses of "size" and "next" members
20642 changed to be "header.size" and "header.next".
20643 * buffer.h (struct buffer): Likewise.
20644 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20645 * frame.h (struct frame): Likewise.
20646 * process.h (struct Lisp_Process): Likewise.
20647 * termhooks.h (struct terminal): Likewise.
20648 * window.c (struct save_window_data, struct saved_window): Likewise.
20649 * window.h (struct window): Likewise.
20650 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20651 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20652 * buffer.c (init_buffer_once): Likewise.
20653 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20655 * process.c (Fformat_network_address): Use local var for size,
20658 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20660 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20661 * data.c (atof): Remove decl; no longer used or needed.
20662 (digit_to_number): Move to lread.c.
20663 (Fstring_to_number): Use new string_to_number function, to be
20664 consistent with how the Lisp reader treats infinities and NaNs.
20665 Do not assume that floating-point numbers represent EMACS_INT
20666 without losing information; this is not true on most 64-bit hosts.
20667 Avoid double-rounding errors, by insisting on integers when
20668 parsing non-base-10 numbers, as the documentation specifies.
20669 * lisp.h (string_to_number): New decl, replacing ...
20670 (isfloat_string): Remove.
20671 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20672 (read1): Do not accept +. and -. as integers; this
20673 appears to have been a coding error. Similarly, do not accept
20674 strings like +-1e0 as floating point numbers. Do not report
20675 overflow for integer overflows unless the base is not 10 which
20676 means we have no simple and reliable way to continue.
20677 Break out the floating-point parsing into a new
20678 function string_to_number, so that Fstring_to_number parses
20679 floating point numbers consistently with the Lisp reader.
20680 (digit_to_number): Move here from data.c. Make it static inline.
20681 (E_CHAR, EXP_INT): Remove, replacing with ...
20682 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20683 (string_to_number): New function, replacing isfloat_string.
20684 This function checks for valid syntax and produces the resulting
20685 Lisp float number too. Rework it so that string-to-number
20686 no longer mishandles examples like "1.0e+". Use strtoumax,
20687 so that overflow for non-base-10 numbers is reported only when
20688 there's no portable and simple way to convert to floating point.
20690 * textprop.c (set_text_properties_1): Rewrite for clarity,
20691 and to avoid GCC warning about integer overflow.
20693 * intervals.h (struct interval): Use EMACS_INT for members
20694 where EMACS_UINT might cause problems. See
20695 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20696 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20697 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20699 (offset_intervals): Tell GCC not to worry about length overflow
20700 when negating a negative length.
20702 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20703 (overrun_check_free): Likewise.
20705 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20706 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20709 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20710 (gnutls_make_error): Rename local to avoid shadowing.
20711 (gnutls_emacs_global_deinit): ifdef out; not used.
20712 (Fgnutls_boot): Use const for pointer to readonly storage.
20713 Comment out unused local. Fix pointer signedness problems.
20715 * lread.c (openp): Don't stuff size_t into an 'int'.
20716 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20717 about possible signed overflow.
20719 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20720 (GDK_KEY_g): Don't define if already defined.
20721 (xg_prepare_tooltip): Avoid pointer signedness problem.
20722 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20724 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20725 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20727 * xfns.c (Fx_window_property): Simplify a bit,
20728 to make a bit faster and to avoid GCC 4.6.0 warning.
20729 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20731 * fns.c (internal_equal): Don't assume size_t fits in int.
20733 * alloc.c (compact_small_strings): Tighten assertion a little.
20735 Replace pEd with more-general pI, and fix some printf arg casts.
20736 * lisp.h (pI): New macro, generalizing old pEd macro to other
20737 conversion specifiers. For example, use "...%"pI"d..." rather
20738 than "...%"pEd"...".
20739 (pEd): Remove. All uses replaced with similar uses of pI.
20740 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20741 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20742 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20743 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20744 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20745 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20746 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20748 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20749 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20750 * print.c (safe_debug_print, print_object): Likewise.
20751 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20753 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20754 avoiding the 0 flag, which is not portable.
20755 * process.c (Fmake_network_process): Use pI to avoid cast.
20756 * region-cache.c (pp_cache): Likewise.
20757 * xdisp.c (decode_mode_spec): Likewise.
20758 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20759 behavior on 64-bit hosts with printf arg.
20760 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20761 (x_stop_queuing_selection_requests): Likewise.
20762 (x_get_window_property): Don't truncate byte count to an 'int'
20765 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20766 here, since it parses constructs like leading '-' and spaces,
20767 which are not wanted; and it overflows with large numbers.
20768 Instead, simply match F[0-9]+, which is what is wanted anyway.
20770 * alloc.c: Remove unportable assumptions about struct layout.
20771 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20772 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20773 (allocate_vectorlike, make_pure_vector): Use the new macros,
20774 plus offsetof, to remove unportable assumptions about struct layout.
20775 These assumptions hold on all porting targets that I know of, but
20776 they are not guaranteed, they're easy to remove, and removing them
20777 makes further changes easier.
20779 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20780 This doesn't fix a bug but makes the code clearer.
20781 (string_overrun_cookie): Now const. Use initializers that
20782 don't formally overflow signed char, to avoid warnings.
20783 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20784 can cause Emacs to crash when string overrun checking is enabled.
20785 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20786 multiple of sizeof (EMACS_INT); it need not be, if
20787 alignof(EMACS_INT) < sizeof (EMACS_INT).
20788 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20790 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
20792 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
20794 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
20796 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
20797 supposed to be handshaking. (Bug#8556)
20798 Reported by Paul Eggert <eggert@cs.ucla.edu>.
20800 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
20802 * lisp.h (Qdebug): List symbol.
20803 * eval.c (Qdebug): Restore global linkage.
20804 * keyboard.c (debug-on-event): New variable.
20805 (handle_user_signal): Break into debugger when debug-on-event
20806 matches the current signal symbol.
20808 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
20810 * alloc.c (check_sblock, check_string_bytes)
20811 (check_string_free_list): Convert to standard C.
20813 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
20815 * w32.c (emacs_gnutls_push): Fix typo.
20817 2011-04-25 Eli Zaretskii <eliz@gnu.org>

21333 However, leave prepare_to_modify_buffer alone. It's never

21371 * xfaces.c (face_at_string_position):
21372 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,

21541 Declare Lisp_Object Q* variables to be 'static' if not exported.
21542 This makes it easier for human readers (and static analyzers)
21543 to see whether these variables are used from other modules.
21544 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

21557 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21559 Make Emacs functions such as Fatom 'static' by default.
21560 This makes it easier for human readers (and static analyzers)
21561 to see whether these functions can be called from other modules.
21562 DEFUN now defines a static function. To make the function external
21563 so that it can be used in other C modules, use the new macro DEFUE.

21569 Remove decls, since these functions are now static.
21570 (Funintern, Fget_internal_run_time): New decls, since these functions
21571 were already external.
21573 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

21581 Mark functions with DEFUE instead of DEFUN,
21582 if they are used in other modules.
21583 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21584 decls for now-static functions.
21585 * buffer.h (Fdelete_overlay): Remove decl.

21621 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21623 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21624 when at ZV. (Bug#8487)
21626 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21628 * charset.c (Fclear_charset_maps): Use xfree instead of free.

21637 (overrun_check_free): Protoize.
21639 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21641 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21642 since callers should never pass a negative size.
21643 Change the signature to match that of plain 'read' and 'write'; see
21644 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21645 * lisp.h: Update prototypes of emacs_write and emacs_read.
21647 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21649 * xdisp.c (redisplay_window): Don't try to determine the character
21650 position of the scroll margin if the window start point w->startp
21651 is outside the buffer's accessible region. (Bug#8468)
21653 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21655 Fix write-region and its subroutines for buffers > 2GB.
21656 * fileio.c (a_write, e_write): Modify declaration of arguments and
21657 local variables to support buffers larger than 2GB.
21658 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21660 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21661 argument, local variables, and return value.
21663 * lisp.h: Update prototypes of emacs_write and emacs_read.
21665 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21667 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21669 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21671 Fix more problems found by GCC 4.6.0's static checks.
21673 * xdisp.c (vmessage): Use a better test for character truncation.
21675 * charset.c (load_charset_map): <, not <=, for optimization,
21676 and to avoid potential problems with integer overflow.
21677 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21678 * casetab.c (set_identity, shuffle): Likewise.
21679 * editfns.c (Fformat): Likewise.
21680 * syntax.c (skip_chars): Likewise.
21682 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21683 This also lets GCC 4.6.0 generate slightly better loop code.
21685 * callint.c (Fcall_interactively): <, not <=, for optimization.
21686 (Fcall_interactively): Count the number of arguments produced,
21687 not the number of arguments given. This is simpler and lets GCC
21688 4.6.0 generate slightly better code.
21690 * ftfont.c: Distingish more carefully between FcChar8 and char.
21691 The previous code passed unsigned char * to a functions like
21692 strlen and xstrcasecmp that expect char *, which does not
21693 conform to the C standard.
21694 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21695 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21696 char * when the C standard requires it.
21698 * keyboard.c (read_char): Remove unused var.
21700 * eval.c: Port to Windows vsnprintf (Bug#8435).
21701 Include <limits.h>.
21702 (SIZE_MAX): Define if the headers do not.
21703 (verror): Do not give up if vsnprintf returns a negative count.
21704 Instead, grow the buffer. This ports to Windows vsnprintf, which
21705 does not conform to C99. Problem reported by Eli Zaretskii.
21706 Also, simplify the allocation scheme, by avoiding the need for
21707 calling realloc, and removing the ALLOCATED variable.
21709 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21711 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21712 But keep the doprint source code for now, as we might revamp it
21713 and use it again (Bug#8435).
21714 * lisp.h (doprnt): Remove.
21715 * Makefile.in (base_obj): Remove doprnt.o.
21716 * deps.mk (doprnt.o): Remove.
21718 error: Print 32- and 64-bit integers portably (Bug#8435).
21719 Without this change, on typical 64-bit hosts error ("...%d...", N)
21720 was used to print both 32- and 64-bit integers N, which relied on
21721 undefined behavior.
21722 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.

21727 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21728 Truncate the output at a character boundary, since vsnprintf does not
21730 * charset.c (check_iso_charset_parameter): Convert internal
21731 character to string before calling 'error', since %c now has the
21733 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21734 overflow when computing char to be passed to 'error'. Do not
21735 pass Lisp_Object to 'error'; pass the integer instead.
21736 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21737 formatted with plain %d.
21739 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21741 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.

21753 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21754 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21755 return ssize_t not "int", and use size_t as the buffer length.
21756 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21757 * gnutls.h: Update declarations.
21758 * process.c (read_process_output): Use ssize_t, to match.

21763 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21765 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21767 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21768 Use unsigned char, to match FcChar8 type definition.
21770 * xterm.c (handle_one_xevent):
21771 * xmenu.c (create_and_show_popup_menu):
21772 * xselect.c (x_decline_selection_request)

21804 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21805 (encode_invocation_designation): Last argument P_NCHARS is now
21807 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.

21874 This avoids several warnings with gcc -Wstrict-overflow.
21875 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21876 directly, rather than having caller test rule sign. This avoids
21877 some unnecessary tests.
21878 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21879 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21880 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21882 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21883 (xfont_open): Avoid unnecessary tests.
21885 * composite.c (composition_gstring_put_cache): Use unsigned integer.

21891 breaking out part of COMPOSITION_DECODE_RULE.
21892 (COMPOSITION_DECODE_RULE): Use it.

21894 by using the new macro.
21896 * textprop.c (set_text_properties_1): Change while to do-while,
21897 since the condition is always true at first.
21899 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21900 (interval_deletion_adjustment): Return unsigned value.

21922 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21924 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21925 (font_score): Avoid potential overflow in diff calculation.
21927 * fns.c (substring_both): Remove var that is set but not used.
21928 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21930 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21932 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21933 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21934 can always succeed if overflow has undefined behavior.
21936 * search.c (boyer_moore, wordify): Remove vars set but not used.
21937 (wordify): Omit three unnecessary tests.
21939 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21940 All callers changed. This avoids the need for an unused var.
21942 * casefiddle.c (casify_region): Remove var that is set but not used.
21944 * dired.c (file_name_completion): Remove var that is set but not used.

21948 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21949 (Finsert_file_contents): Remove unnecessary code checking fd.
21951 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21952 Check for integer overflow on size calculations.
21954 * buffer.c (Fprevious_overlay_change): Remove var that is set
21957 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21958 Remove vars that are set but not used.
21959 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.

21962 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21964 * image.c (lookup_image): Remove var that is set but not used.
21965 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21967 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21968 that are set but not used.
21970 * xfns.c (make_invisible_cursor): Don't return garbage
21971 if XCreateBitmapFromData fails (Bug#8410).
21973 * xselect.c (x_get_local_selection, x_handle_property_notify):
21974 Remove vars that are set but not used.
21976 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21977 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21979 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21980 Remove var that is set but not used.
21981 (scroll_bar_windows_size): Now size_t, not int.
21982 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21983 Check for overflow.
21985 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21986 (map_tty_color) [!defined MSDOS]: Likewise.
21988 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21990 * coding.c: Remove vars that are set but not used.

21994 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21995 (decode_coding_charset): Remove vars that are set but not used.
21997 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21998 that is set but not used.
22000 * print.c (print_object): Remove var that is set but not used.
22002 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22003 The gnulib version avoids calling malloc in the usual case,
22004 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22005 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22006 * filelock.c (current_lock_owner): Likewise.
22007 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22008 * sysdep.c: Include allocator.h, careadlinkat.h.
22009 (emacs_no_realloc_allocator): New static constant.
22010 (emacs_readlink): New function.
22011 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22012 ../lib/careadlinkat.h.
22014 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22016 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22017 first non-nil return value).

22031 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22032 and thereabouts. All callers changed.
22033 (get_per_char_metric): Remove parameter `f', unused since
22034 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

22038 do not dereference NULL upon failed strdup
22039 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.

22068 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22070 * keyboard.c (eval_dyn): New fun.
22071 (menu_item_eval_property): Use it.

22075 * fns.c (concat, mapcar1): Accept byte-code-functions.
22077 * eval.c (Fsetq): Handle lexical vars.
22078 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22079 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22080 (FletX, Flet): Obey lexical binding.
22081 (Fcommandp): Handle closures.
22082 (Feval): New `lexical' arg.
22083 (eval_sub): New function extracted from Feval. Use it almost
22084 everywhere where Feval was used. Look up vars in lexical env.
22086 (Ffunctionp): Move from subr.el.
22087 (Ffuncall): Handle closures.
22088 (apply_lambda): Remove `eval_flags'.
22089 (funcall_lambda): Handle closures and new byte-code-functions.
22090 (Fspecial_variable_p): New function.
22091 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22092 but without exporting it to Lisp.
22094 * doc.c (Fdocumentation, store_function_docstring):
22095 * data.c (Finteractive_form): Handle closures.
22097 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22100 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22102 (exec_byte_code): New function extracted from Fbyte_code to handle new
22103 calling convention for byte-code-functions. Add new byte-codes.
22105 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22107 * alloc.c (Fmake_symbol): Init new `declared_special' field.

22117 Limit scrolling to 100 screen lines.
22118 (redisplay_window): Even when falling back on "recentering",
22119 position point in the window according to scroll-conservatively,
22120 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22122 (try_scrolling): When point is above the window, allow searching
22123 as far as scroll_max, or one screenful, to compute vertical
22124 distance from PT to the scroll margin position. This prevents
22125 try_scrolling from unnecessarily failing when
22126 scroll-conservatively is set to a value slightly larger than the
22127 window height. Clean up the case of PT below the margin at bottom
22128 of window: scroll_max can no longer be INT_MAX. When aggressive
22129 scrolling is in use, don't let point enter the opposite scroll
22130 margin as result of the scroll.
22131 (syms_of_xdisp) <scroll-conservatively>: Document the
22132 threshold of 100 lines for never-recentering scrolling.

22140 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22141 (redisplay_internal): Remove parameter `preserve_echo_area',
22142 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22144 * indent.c (Fvertical_motion):
22145 * window.c (window_scroll_pixel_based, Frecenter):
22146 Don't pass `need_y_p' to `move_it_by_lines'.
22148 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22150 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22151 steal a few bits to be more compact.

22153 Remove unneeded casts.
22155 * bytecode.c (Fbyte_code): CAR and CDR can GC.

22166 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22167 Remove unused local var.
22169 * editfns.c (Fmessage_box): Remove unused local var.
22171 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22172 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22173 Omit unused local vars.
22174 * window.c (shrink_windows): Omit unused local var.
22175 * menu.c (digest_single_submenu): Omit unused local var.
22176 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22177 Omit unused local var.
22179 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22180 Don't assume string length fits in int.
22181 (keyremap_step, read_key_sequence): Use size_t for sizes.
22182 (read_key_sequence): Don't check last_real_key_start redundantly.
22184 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22185 instead of alloca (Bug#8344).
22187 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22188 (Fbacktrace_frame): Don't assume nframes fits in int.
22190 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22192 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22195 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22197 * cm.c (calccost): Turn while-do into do-while, for clarity.
22199 * keyboard.c (syms_of_keyboard): Use the same style as later
22200 in this function when indexing through an array. This also
22201 works around GCC bug 48267.
22203 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22205 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

22208 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22210 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22211 This avoids undefined behavior on integer overflow, and is a bit
22212 more convenient anyway since it is compared to a size_t variable.
22214 Variadic C functions now count arguments with size_t, not int.
22215 This avoids an unnecessary limitation on 64-bit machines, which
22216 caused (substring ...) to crash on large vectors (Bug#8344).
22217 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22218 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
22219 All variadic functions and their callers changed accordingly.
22220 (struct gcpro.nvars): Now size_t, not int. All uses changed.

22222 * editfns.c (general_insert_function): Likewise.
22223 * eval.c (struct backtrace.nargs, interactive_p)
22224 (internal_condition_case_n, run_hook_with_args, apply_lambda)
22225 (funcall_lambda, mark_backtrace): Likewise.
22226 * fns.c (concat): Likewise.
22227 * frame.c (x_set_frame_parameters): Likewise.
22228 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22229 0 if not found, not -1. All callers changed.
22231 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22232 (stack_copy_size): Now size_t, not int.
22233 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

22239 All callers changed.
22241 * lisp.h (multibyte_char_to_unibyte):
22242 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22243 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

22253 * keyboard.c (safe_run_hook_funcall): New function.
22254 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22255 don't set the hook to nil, but remove the offending function instead.
22256 (Qcommand_hook_internal): Remove, unused.
22257 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22258 Vcommand_hook_internal.
22260 * eval.c (enum run_hooks_condition): Remove.
22261 (funcall_nil, funcall_not): New functions.
22262 (run_hook_with_args): Call each function through a `funcall' argument.

22272 * print.c (strout): Remove parameter `multibyte', unused since
22273 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
22275 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
22276 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
22277 All callers changed.
22279 * w32.c (_wsa_errlist): Use braces for struct initializers.

22285 used outside xdisp.c).
22286 (cursor_row_p): Remove parameter `w', unused since
22287 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

22289 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
22290 All callers changed.
22292 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22294 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

22323 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
22325 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
22327 * w32.c (read_unc_volume): Use parameter `henum', instead of
22328 global variable `wget_enum_handle'.
22330 * keymap.c (describe_vector): Remove parameters `indices' and
22331 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

22346 * gtkutil.c (xg_maybe_add_timer):
22347 * keyboard.c (readable_events):
22348 * process.c (wait_reading_process_output):
22349 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.

22426 2011-03-23 Julien Danjou <julien@danjou.info>
22428 * term.c (Fsuspend_tty, Fresume_tty):
22429 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22430 * window.c (temp_output_buffer_show):

22437 * callint.c (Fcall_interactively):
22438 * buffer.c (Fkill_all_local_variables):
22439 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22441 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22442 unconditionally since it does the check itself.
22444 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22446 Fix more problems found by GCC 4.5.2's static checks.
22448 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22449 the first time through the loop, since we know p0 < p1 then.
22450 This also avoids a gcc -Wstrict-overflow warning.
22452 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22453 leading to a memory leak, possible in functions like
22454 load_charset_map_from_file that can allocate an unbounded number
22455 of objects (Bug#8318).
22457 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22458 that could (at least in theory) be that large.
22460 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22461 This is less likely to overflow, and avoids undefined behavior if
22462 overflow does occur. All callers changed. Use strtoul to scan
22463 for the unsigned long integer.
22464 (pint2hrstr): Simplify and tune code slightly.
22465 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

22473 This also avoids a warning with gcc -Wstrict-overflow.
22475 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22478 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22480 * process.c (Fmake_network_process): Use socklen_t, not int,
22481 where POSIX says socklen_t is required in portable programs.
22482 This fixes a porting bug on hosts like 64-bit HP-UX, where
22483 socklen_t is wider than int (Bug#8277).
22484 (Fmake_network_process, server_accept_connection):
22485 (wait_reading_process_output, read_process_output):
22488 * process.c: Rename or move locals to avoid shadowing.

22495 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22496 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22498 Make tparam.h and terminfo.c consistent.
22499 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22500 Include tparam.h instead, since it declares them.
22501 * cm.h (PC): Remove extern decl; tparam.h now does this.
22502 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22503 * terminfo.c: Include tparam.h, to check interfaces.
22504 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22505 (tparam): Adjust signature to match interface in tparam.h;
22506 this removes some undefined behavior. Check that outstring and len
22507 are zero, which they always are with Emacs.
22508 * tparam.h (PC, BC, UP): New extern decls.
22510 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22511 (xftfont_open): Rename locals to avoid shadowing.
22513 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
22514 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
22515 (OTF_TAG_SYM): Omit macro if not needed.
22516 (ftfont_list): Remove unused local.
22517 (get_adstyle_property, ftfont_pattern_entity):
22518 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
22519 Rename locals to avoid shadowing.
22521 * xfont.c (xfont_list_family): Mark var as initialized.
22523 * xml.c (make_dom): Now static.
22525 * composite.c (composition_compute_stop_pos): Rename local to
22527 (composition_reseat_it): Remove unused locals.
22528 (find_automatic_composition, composition_adjust_point): Likewise.
22529 (composition_update_it): Mark var as initialized.
22530 (find_automatic_composition): Mark vars as initialized,
22531 with a FIXME (Bug#8290).
22533 character.h: Rename locals to avoid shadowing.
22534 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22535 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22536 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22537 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22538 to avoid shadowing.
22540 * textprop.c (property_change_between_p): Remove; unused.
22542 * intervals.c (interval_start_pos): Now static.
22544 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
22546 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
22547 Rename locals to avoid shadowing.
22549 * sound.c (wav_play, au_play, Fplay_sound_internal):
22550 Fix pointer signedness.
22551 (alsa_choose_format): Remove unused local var.
22552 (wav_play): Initialize a variable to 0, to prevent undefined
22553 behavior (Bug#8278).
22555 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22557 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22559 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22560 clobbering (Bug#8298).
22561 * sysdep.c (sys_subshell): Likewise.
22562 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22564 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22565 This should get cleaned up, so that child_setup has the
22566 same signature on all platforms.
22568 * callproc.c (call_process_cleanup): Now static.
22569 (relocate_fd): Rename locals to avoid shadowing.
22571 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22573 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22574 not to be necessary, and produces flickering.
22576 2011-03-20 Glenn Morris <rgm@gnu.org>
22578 * config.in: Remove file.
22580 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
22582 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
22583 are now in src/globals.h.
22584 (syms_of_minibuf): Remove spurious & from previous change.

22601 2011-03-17 Eli Zaretskii <eliz@gnu.org>
22603 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

22699 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22700 some of which prompt warnings from gcc -Wbad-function-cast.
22701 (Fformat_time_string, Fencode_time, Finsert_char):

22738 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22739 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22740 to use the following functions instead of these macros.
22741 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22742 EMACS_INT, since callers assume the returned value fits in int.
22743 (upcase1): Likewise, for UPCASE_TABLE.
22744 (uppercasep, lowercasep, upcase): New static inline functions.
22745 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22755 (regex_compile, re_match_2_internal): Mark locals as initialized.
22756 (RETALLOC_IF): Define only if needed.
22757 (WORDCHAR_P): Likewise. This one is never needed, but is used
22758 only in a comment talking about a compiler bug, so put inside
22759 the #if 0 of that comment.
22760 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22761 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

22787 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22788 New macros, so that the caller can use some names other than
22789 gcpro1, gcpro2, etc.
22790 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22792 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22793 argument, for consistency with GCPRO2_VAR, etc: it is now the
22794 prefix of the variable, not the variable itself. All uses
22796 * dired.c (directory_files_internal, file_name_completion):
22797 Rename locals to avoid shadowing.
22799 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22800 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22801 dired.c's scmp function, had undefined behavior.
22802 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22803 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22804 * buffer.h: ... to here, because these macros use current_buffer,
22805 and the new implementation with inline functions needs to have
22806 current_buffer in scope now, rather than later when the macros
22808 (downcase, upcase1): New static inline functions.
22809 (DOWNCASE, UPCASE1): Reimplement using these functions.
22810 This avoids undefined behavior in expressions like
22811 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22812 from race conditions in accessing the global variables
22813 case_temp1 and case_temp2.
22814 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22815 * lisp.h (case_temp1, case_temp2): Remove their decls.
22816 * character.h (ASCII_CHAR_P): Move from here ...
22817 * lisp.h: ... to here, so that the inline functions mentioned
22818 above can use them.
22820 * dired.c (directory_files_internal_unwind): Now static.
22822 * fileio.c (file_name_as_directory, directory_file_name):

22825 (file_name_as_directory): Use const pointers when appropriate.
22826 (Fexpand_file_name): Likewise. In particular, newdir might
22827 point at constant storage, so make it a const pointer.
22828 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22829 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22831 (Fset_file_times, Finsert_file_contents, auto_save_error):

22836 to avoid shadowing.
22838 * marker.c (bytepos_to_charpos): Remove; unused.
22840 * lisp.h (verify_bytepos, count_markers): New decls,
22841 so that gcc does not warn that these functions aren't declared.
22843 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22844 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22845 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22846 (copy_text): Remove unused local var.
22848 * filelock.c (within_one_second): Now static.
22849 (lock_file_1): Rename local to avoid shadowing.
22851 * buffer.c (fix_overlays_before): Mark locals as initialized.
22852 (fix_start_end_in_overlays): Likewise. This function should be
22853 simplified by using pointers-to-pointers, but that's a different
22855 (switch_to_buffer_1): Now static.
22856 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22857 (report_overlay_modification): Rename locals to avoid shadowing.
22859 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
22860 Fix pointer signedness issue.
22861 (sys_subshell): Mark local as volatile if checking for lint,
22862 to suppress a gcc -Wclobbered warning that does not seem to be right.
22863 (MAXPATHLEN): Define only if needed.
22865 * process.c (serial_open, serial_configure): Move decls from here ...
22866 * systty.h: ... to here, so that they can be checked.
22868 * fns.c (get_random, seed_random): Move extern decls from here ...
22869 * lisp.h: ... to here, so that they can be checked.
22871 * sysdep.c (reset_io): Now static.
22872 (wait_for_termination_signal): Remove; unused.
22874 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

22877 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
22878 (DENSE_TABLE_SIZE): Remove; unused.
22879 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22880 (describe_map_tree):
22881 Rename locals to avoid shadowing.
22883 * keyboard.c: Declare functions static if they are not used elsewhere.

22968 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
22969 These macros can no longer be used for assignment.

23030 For example, without this patch (encode-time 0 0 0 1 1
23031 1152921504606846976) returns the obviously-bogus value (-948597
23032 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
23033 reports time overflow. See
23034 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
23035 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
