338 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
340 * xdisp.c (init_iterator): Simplify because both character and byte
341 positions are either specified or -1. Add eassert. Adjust comment.

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

592 * sysdep.c (list_system_processes)
593 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
594 Make it a stub in this case; otherwise the build might fail,
595 and this code hasn't been tested on such hosts anyway.

611 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
612 * filelock.c: Include <c-ctype.h>.
613 (MAX_LFINFO): New top-level constant.
614 (lock_info_type): Remove members pid, boot_time. Add members at,
615 dot, colon. Change user member to be the entire buffer, not a
616 pointer. This allows us to handle the case where a foreign
617 pid or boot time exceeds the local range. All uses changed.
618 (LINKS_MIGHT_NOT_WORK): New constant.
619 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
620 (defined_WINDOWSNT): Remove.
621 (MAKE_LOCK_NAME, file_in_lock_file_name):
622 Always use .#FILE (not .#-FILE) for the file lock,
623 even if it is a regular file.
624 (rename_lock_file): New function.
625 (create_lock_file): Use it.
626 (create_lock_file, read_lock_data):
627 Prefer a symbolic link for the lock file, falling back on a
628 regular file if symlinks don't work. Do not try to create
629 symlinks on MS-Windows, due to security hassles. Stick with
630 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
631 link, rename, unlink, mkstemp) when creating locks, as a GNUish
632 host may be using a Windowsish file system, and cannot use
633 MS-Windows-only system calls. Fall back on mktemp if mkstemp
634 doesn't work. Don't fail merely because of a symlink-contents
635 length limit in the current file system; fall back on regular
636 files. Increase the symlink contents length limit to 8 KiB, this
637 should be big enough for any real use and doesn't crunch the
639 (create_lock_file, lock_file_1, read_lock_data):
640 Simplify allocation of lock file buffers now that they fit in 8 KiB.
641 (lock_file_1): Return error number, not bool. All callers changed.
642 (ELOOP): New macro, if not already defined.
643 (read_lock_data): Return size of lock file contents, not Lisp object.
644 All callers changed. Handle a race condition if some other process
645 replaces a regular-file lock with a symlink lock or vice versa,
646 while we're trying to read the lock.
647 (current_lock_owner): Parse contents more carefully, to help avoid
648 confusing a regular-file lock with some other application's use
649 of the file. Check for lock file contents being too long, or
650 not parsing correctly.
651 (current_lock_owner, lock_file):
652 Allow foreign pid and boot times that exceed the local range.
653 (current_lock_owner, lock_if_free, lock_file):
654 Simplify allocation of lock file contents.
655 * w32.c (sys_rename_replace): New function, containing most of
656 the contents of the old sys_rename.
657 (sys_rename): Use it.
658 (fchmod): New dummy function.
659 * w32.h (sys_rename_replace, fchmod): New decls.
661 2013-03-05 Eli Zaretskii <eliz@gnu.org>
663 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
664 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
665 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
666 <dmantipov@yandex.ru>.
668 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
670 * composite.c (get_composition_id, fill_gstring_header):
671 Use make_uninit_vector where appropriate.
672 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
673 * xselect.c (clean_local_selection_data): Likewise.
675 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
677 Fix misuse of ImageMagick that caused core dump (Bug#13846).
678 * image.c (imagemagick_load_image): Calculate height and width
679 after flattening the image, not before.
681 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
683 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
684 * ftfont.c (ftfont_shape_by_flt): Likewise.
685 * w32uniscribe.c (uniscribe_shape): Likewise.
687 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
689 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
690 The old approach, which fell back on DIR/.#FILE.0 through
691 DIR/.#FILE.9, had race conditions that could not be easily fixed.
692 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
693 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
694 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
695 because the locking mechanism was never reliable in that case).
696 This patch fixes this and other bugs discovered by a code
697 inspection that was prompted by
698 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
699 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
700 to avoid interoperability problems between the MS-Windows and
701 non-MS-Windows implementations. MS-Windows and non-MS-Windows
702 instances of Emacs now ignore each others' locks.
703 * filelock.c (defined_WINDOWSNT): New constant.
704 (MAKE_LOCK_NAME, fill_in_lock_file_name):
705 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
706 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
707 regular files on MS-Windows hosts.
708 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
709 Use SAFE_ALLOCA to avoid problems with long file names.
710 (MAX_LFINFO): Now a local constant, not a global macro.
711 (IS_LOCK_FILE): Remove.
712 (lock_file_1): Don't inspect errno if symlink call succeeds;
714 (lock_file): Document that this function can return if lock
716 (lock_file): Don't access freed storage.
718 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

722 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
724 * textprop.c: Use bool for booleans.
725 (validate_interval_range, Fadd_text_properties)
726 (Fremove_text_properties): Prefer bool to int when either works.
728 2013-03-02 Eli Zaretskii <eliz@gnu.org>
730 * textprop.c (Fadd_text_properties, Fremove_text_properties):
731 If the interval tree changes as a side effect of calling
732 modify_region, re-do processing starting from the call to
733 validate_interval_range. (Bug#13743)
735 2013-02-28 Eli Zaretskii <eliz@gnu.org>
737 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
740 2013-02-27 Eli Zaretskii <eliz@gnu.org>
742 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
743 _SH_DENYRW flag, instead of emacs_open, to deny any other process
744 access to the lock file until it is written and closed.
747 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
749 * callint.c (Qcall_interactively):

759 Minor textprop integer cleanup.
760 * intervals.h, textprop.c (add_text_properties_from_list):
761 Return void, not int, since nobody uses the return value.
762 * textprop.c (validate_plist, add_properties, remove_properties)
763 (Fadd_text_properties):
764 Don't assume list length fits in int.
765 (interval_has_all_properties, interval_has_some_properties)
766 (interval_has_some_properties_list, add_properties, remove_properties)
767 (Fadd_text_properties, Fremove_text_properties)
768 (Fremove_list_of_text_properties, text_property_stickiness):
769 Use bool for booleans.
770 (Fadd_text_properties, Fremove_text_properties):
771 (Fremove_list_of_text_properties):
772 Reindent do-while as per GNU style.

776 Implement CLASH_DETECTION for MS-Windows.
778 * filelock.c [WINDOWSNT]: Include w32.h.
779 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
780 function of that name. Up-case the macro arguments.
781 (IS_LOCK_FILE): New macro.
782 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
783 (create_lock_file): New function, with body extracted from
785 [WINDOWSNT]: Implement lock files by writing a regular file with
786 the lock information as its contents.
787 (read_lock_data): New function, on Posix platforms just calls
789 [WINDOWSNT]: Read the lock info from the file.
790 (current_lock_owner): Call read_lock_data instead of calling
791 emacs_readlinkat directly.
792 (lock_file) [WINDOWSNT]: Run the file name through
795 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
796 just check if the process by that PID exists.
798 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
799 also present, as doing so will fail to error out if the file
802 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
804 * textprop.c (Fadd_text_properties, Fremove_text_properties)
805 (Fremove_list_of_text_properties): Skip all of the intervals in
806 the region between START and END that already have resp. don't
807 have the requested properties, not just the first one.

957 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
959 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
961 2013-02-15 Eli Zaretskii <eliz@gnu.org>
963 * keyboard.c (read_char): Fix calculation of auto-save time out
964 when auto-save-timeout is less than 4. (Bug#13720)
966 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
967 time. Improve diagnostics in DebPrint. (Bug#13546)
969 * w32.c (sys_socket, sys_bind, sys_connect, sys_gethostname)
970 (sys_gethostbyname, sys_getservbyname, sys_getpeername)
971 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
972 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
973 make sure errno is set to an appropriate value. (Bug#13546)
974 (socket_to_fd): Add assertion against indexing fd_info[] with a
975 value that is out of bounds.
976 (sys_accept): If fd is negative, do not set up the child_process
977 structure for reading.
979 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
981 * composite.c (fill_gstring_header): Remove useless prototype.
983 * lisp.h (message_dolog, compile_pattern): Adjust prototype.
984 * print.c (PRINTDECLARE, print_object):
985 * search.c (compile_pattern, fast_looking_at, search_buffer):
986 (simple_search, boyer_moore, Freplace_match):
987 * xdisp.c (c_string_pos, number_of_chars, message_dolog):
988 (get_overlay_arrow_glyph_row, display_mode_element):
989 (decode_mode_spec_coding, message3):
990 * xfaces.c (face_at_string_position): Use bool for booleans.
993 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
995 Fix AIX port (Bug#13650).
996 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
997 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
998 was #undeffed earlier, so it cannot be used as a macro here.
999 Use the constant and not the macro.
1001 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1003 * w32proc.c (new_child): If no vacant slots are found in
1004 child_procs[], make another pass looking for slots whose process
1005 has exited or died. (Bug#13546)
1007 * w32.c (sys_pipe): When failing due to file descriptors above
1008 MAXDESC, set errno to EMFILE.
1009 (_sys_read_ahead): Update cp->status when failing to read serial
1010 communications input, so that the status doesn't stay at
1011 STATUS_READ_IN_PROGRESS. (Bug#13546)
1013 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1015 * gtkutil.c (tb_size_cb): New function.
1016 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
1018 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1020 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
1023 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
1025 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1027 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
1029 * font.c (font_range): Add pos_byte argument. Adjust comment
1030 and break long line.
1031 * font.h (font_range): Adjust prototype.
1032 * composite.c (autocmp_chars): Pass byte position to font_range.
1033 Break long line. Remove useless prototype and format comment.
1035 2013-02-13 Glenn Morris <rgm@gnu.org>
1037 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1039 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1041 Improve AIX port some more (Bug#13650).
1042 With this, it should be as good as it was in 23.3, though it's
1043 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1044 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1045 * unexaix.c (start_of_text): Remove.
1046 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1047 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1048 (orig_load_scnptr, orig_data_scnptr):
1049 Now off_t, not long, since they are file offsets.
1050 (make_hdr): Use _data, not start_of_data ().
1051 This is the key part of the fix.
1052 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1053 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1055 * pre-crt0.c (data_start): Initialize to 1.
1056 This ports to compilers that optimize the external declaration
1057 'int x = 0;' as if it were 'int x;' to shrink the executable.
1059 Improve AIX port (Bug#13650).
1060 This doesn't fix the bug, but it makes progress: Emacs builds now.
1061 * unexaix.c: Include inttypes.h, stdarg.h.
1062 (report_error, report_error_1): Mark as _Noreturn.
1063 (report_error): Don't report the wrong errno.
1064 (report_error_1): Now varargs. All callers changed.
1065 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1066 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1067 (write_ptr): Use %p to print address rather than %lx and a cast
1068 to unsigned long. Grow buffer a bit, to be safer.
1070 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1072 * bidi.c (bidi_resolve_neutral): After finding the next
1073 non-neutral character, accept NEUTRAL_ON type as well, because
1074 directional control characters, such as LRE and RLE, have their
1075 type converted to that by bidi_resolve_weak. This avoids aborts
1076 when LRE/RLE follows a run of neutrals.
1077 (bidi_move_to_visually_next): Assert that return value of
1078 bidi_peek_at_next_level is non-negative. Negative values will
1081 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1083 Minor getenv-related fixes.
1084 * callproc.c (Fcall_process_region) [!DOS_NT]:
1085 Avoid unnecessary duplicate call to getenv.
1086 * callproc.c (init_callproc):
1087 * dispnew.c (init_display):
1088 * sysdep.c (sys_subshell):
1089 Omit unnecessary cast of getenv or egetenv.
1091 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1093 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1094 Update dependencies.
1096 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1098 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1100 (display_line): Set w->region_showing to the value of
1101 it->region_beg_charpos, not to -1. This fixes redisplay
1102 optimization when cursor is moved up after M->. (Bug#13623)
1104 (try_scrolling): Scroll text up more if point is too close to ZV
1105 and inside the scroll margin. This makes sure point is moved
1106 outside the scroll margin in these cases.
1108 * window.h (struct window): region_showing can no longer be
1111 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1113 Tune by using memchr and memrchr.
1114 * doc.c (Fsnarf_documentation):
1115 * fileio.c (Fsubstitute_in_file_name):
1116 * search.c (find_newline, scan_newline):
1117 * xdisp.c (pos_visible_p, display_count_lines):
1118 Use memchr and memrchr rather than scanning byte-by-byte.
1119 * search.c (find_newline): Rename from scan_buffer.
1120 Omit first arg TARGET, as it's always '\n'. All callers changed.
1122 Clean up read_key_sequence a tiny bit more.
1123 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1124 (read_key_sequence): Remove unused locals.
1126 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1128 Clean up read_key_sequence a bit; reread active keymaps after first event.
1129 * keyboard.c (read_char, read_char_x_menu_prompt)
1130 (read_char_minibuf_menu_prompt):
1131 Replace nmaps+maps with a single `map' arg.
1132 (follow_key): Operate on a single map.
1133 (active_maps): New function.
1134 (test_undefined): Also return true for nil bindings.
1135 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1136 a single (composed) keymap. Remember `first_event' to choose the right
1137 set of active keymaps. Recompute the set of keymaps after receiving
1138 the first event. Remove GOBBLE_FIRST_EVENT.
1139 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1140 * keyboard.h (read_char): Update declaration.
1141 * lread.c (read_filtered_event): Adjust call to read_char.
1143 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1145 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1146 Don't use the limitation on backwards movement when lines are truncated
1147 in the window. (Bug#13675)
1149 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1151 * marker.c (set_marker_internal): If desired position is passed
1152 as a marker, avoid call to buf_charpos_to_bytepos.
1153 * window.c (Fset_window_point): Omit redundant type checking.
1154 (Fset_window_start): Likewise. Format comment.
1155 (window_scroll_pixel_based): Use set_marker_restricted_both
1156 with character and byte positions obtained from an iterator.
1157 (Fset_window_configuration): Use set_marker_restricted_both.
1158 * xdisp.c (message_dolog): Likewise.
1160 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1162 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1163 When text lines are longer than window's screen lines, don't move back
1164 too far. This speeds up some redisplay operations. (Bug#13675)
1166 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1168 * syntax.c (scan_sexps_forward): Fix byte position calculation
1169 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1171 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
1173 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
1174 that was not needed.
1176 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1178 Minor hashing refactoring.
1179 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1180 (sxhash_float): Return EMACS_UINT, for consistency with the other
1182 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1183 non-static inline function and therefore can't use static vars.
1184 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1185 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1186 with the other hash functions.
1188 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1190 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1191 XXXXXX part of the temporary file pattern is not downcased even
1192 when w32-downcase-file-names is non-nil. (Bug#13661)
1194 * xdisp.c (decode_mode_spec): Remove handling of %t.
1196 * msdos.c (careadlinkatcwd): Remove.
1198 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1200 * lread.c (skip_dyn_bytes): New function (bug#12598).
1201 (read1): Use it. Use getc instead of READCHAR to read bytes.
1202 (load_each_byte): Remove. Update users.
1204 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1206 * search.c (scan_buffer): Calculate end byte position just once.
1207 (scan_newline): Do not recalculate start_byte.
1208 (search_command): Use eassert.
1209 * syntax.c (struct lisp_parse_state): New member location_byte.
1210 (scan_sexps_forward): Record from_byte and avoid redundant
1211 character to byte position calculation ...
1212 (Fparse_partial_sexp): ... here. Break too long line.
1214 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1216 * lisp.h (make_uninit_vector): New function.
1217 * alloc.c (Fvector, Fmake_byte_code):
1218 * ccl.c (Fregister_ccl_program):
1219 * charset.c (Fdefine_charset_internal, define_charset_internal):

1222 * font.c (Fquery_font, Ffont_info, syms_of_font):
1223 * fontset.c (FONT_DEF_NEW, Fset_fontset_font):
1224 * ftfont.c (ftfont_shape_by_flt):

1226 * nsselect.m (clean_local_selection_data):
1227 * syntax.c (init_syntax_once):
1228 * w32unsubscribe.c (uniscribe_shape):
1229 * window.c (Fcurrent_window_configuration):
1230 * xfaces.c (Fx_family_fonts):
1231 * xselect.c (selection_data_to_lisp_data): Use it.
1233 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
1235 * coding.c (Fdefine_coding_system_internal): Use AREF where
1236 argument is known to be a vector.
1237 * fns.c (Flocale_info): Likewise for ASET.
1238 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1239 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1241 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1243 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1246 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
1247 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
1248 updateCollectionBehaviour.
1250 * nsterm.m (NEW_STYLE_FS): Remove.
1251 (ns_last_use_native_fullscreen): New variable.
1252 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
1253 (x_set_window_size): Do not take title bar and tool bar into account
1254 if isFullscreen returns YES.
1255 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1256 (check_native_fs): New function.
1257 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
1258 (ns_term_init): Remove NEW_STYLE_FS.
1259 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
1260 and tool bar if isFullscreen returns NO.
1261 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
1262 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
1263 with HAVE_NATIVE_FS.
1264 (window:willUseFullScreenPresentationOptions:): New method.
1265 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
1266 Hide toolbar if not enabled (Bug#13444).
1267 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
1268 Restore tool bar if enabled, hide it otherwise (Bug#13444).
1269 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
1270 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
1271 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
1272 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
1273 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1274 (syms_of_nsterm): Add ns-use-native-fullscreen.
1276 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1278 * fileio.c (Qchoose_write_coding_system): Now static.
1280 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1282 * xdisp.c (window_buffer_changed): region_showing can be negative,
1283 which still means region is being displayed.
1284 (redisplay_internal): Resurrect code that forced redisplay of the
1285 whole window when showing region and the mark has changed.
1286 Record the new mark position to allow redisplay optimizations.
1287 (display_line): If it->region_beg_charpos is non-zero, set the
1288 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1290 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1291 not bitfield of 1 bit.
1293 2013-02-03 Daniel Colascione <dancol@dancol.org>
1295 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1296 daemon mode works on cygw32 when Emacs is installed and not just
1299 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1301 Avoid file time stamp bug on MS-Windows (Bug#13149).
1302 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1303 as FAT32 doesn't update time stamps when truncating them.
1304 Also, check that a file time stamp is not a multiple of 100 ns;
1305 this should catch all instances of the problem on MS-Windows,
1306 as its native file system resolution is 100 ns or worse, and
1307 checking for a non-multiple of 100 ns should impose only a small
1308 overhead on systems with ns resolution.
1310 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1312 Avoid encoding file names on MS-Windows when they need to be run
1313 through dostounix_filename.
1314 * w32.c (normalize_filename): Accept an additional argument
1315 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1316 downcase it even if w32-downcase-file-names is non-nil.
1317 (dostounix_filename): Accept an additional argument MULTIBYTE and
1318 pass it to normalize_filename.
1319 (emacs_root_dir): Adjust.
1321 * msdos.h (dostounix_filename): Adjust prototype.
1323 * w32.h (dostounix_filename): Adjust prototype.
1325 * msdos.c (dostounix_filename): Accept an additional argument and
1327 (init_environment): Adjust callers of dostounix_filename.
1329 * fileio.c (Ffile_name_directory, file_name_as_directory)
1330 (directory_file_name, Fexpand_file_name)
1331 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1333 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1335 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1336 variables, as egetenv is case-insensitive for DOS_NT.
1338 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1339 with an encoded file name.
1341 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1342 Adjust calls to dostounix_filename.
1344 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1346 * unexw32.c (unexec): Adjust call to dostounix_filename.
1348 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1350 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1353 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1356 * callproc.c (Fcall_process): Make sure program name in PATH and
1357 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1358 is passed to exec/spawnve, which fails unless the file-name
1361 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1362 even if w32-quote-process-args is nil.
1364 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1366 Fix timestamp bug when write-region appends nothing (Bug#13149).
1367 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1368 the file's time stamp doesn't change if Emacs happens to write nothing
1369 to the file, and on a buggy file system this could cause Emacs to
1370 incorrectly infer that the file system doesn't have the bug.
1371 Avoid this problem by inhibiting the inference in this case.
1373 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1375 * window.h (struct window): Convert base_line_number, base_line_pos
1376 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1377 Convert region_showing member from Lisp_Object to bitfield.
1378 Remove sequence_number member. Adjust comments.
1379 * window.c (sequence_number): Remove.
1380 (make_window): Initialize column_number_displayed.
1381 * print.c (print_object): Follow the printed representation of
1382 frames and print window pointer to distinguish between windows.
1383 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1384 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1385 (wset_column_number_displayed, wset_region_showing): Remove.
1386 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1387 (try_scrolling, try_cursor_movement, redisplay_window)
1388 (try_window_reusing_current_matrix, try_window_id, display_line)
1389 (display_mode_lines, decode_mode_spec): Adjust users.
1390 * .gdbinit (pwinx): Do not print sequence_number.
1392 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1394 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1395 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1396 * dired.c: Include <fcntl.h>.
1397 (open_directory): New function, which uses open and fdopendir
1398 rather than opendir. DOS_NT platforms still use opendir, though.
1399 (directory_files_internal, file_name_completion): Use it.
1400 (file_attributes): New function, with most of the old Ffile_attributes.
1401 (directory_files_internal, Ffile_attributes): Use it.
1402 (file_attributes, file_name_completion_stat): First arg is now fd,
1403 not dir name. All uses changed. Use fstatat rather than lstat +
1405 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1406 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1407 (emacs_readlinkat): New function, with much of the old
1408 Ffile_symlink_p, but with an fd argument for speed.
1409 It uses readlinkat rather than careadlinkatcwd, so that it
1410 need not assume the working directory.
1411 (Ffile_symlink_p): Use it.
1412 * filelock.c (current_lock_owner): Use emacs_readlinkat
1413 rather than emacs_readlink.

1433 (sys_close): Zero out the flags for the file descriptor before
1434 closing it. (Bug#13546)
1436 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1437 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1438 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1441 * w32.c (w32_get_long_filename, init_environment, readlink):
1442 Support file names encoded in DBCS codepages.
1443 (readlink): Use the current file-name-coding-system, not the ANSI
1444 codepage, to decode and handle targets of symlinks.
1446 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1448 * w32.c (opendir): Now accepts a 'const char *'.

1452 Remove obsolete redisplay code. See the discussion at
1453 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1454 * dispnew.c (preemption_period, preemption_next_check): Remove.
1455 (Vredisplay_preemption_period): Likewise.
1456 (update_frame, update_single_window, update_window, update_frame_1):
1457 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1458 used, following the 2012-06-22 change.
1460 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1462 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1464 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1466 * font.c (num_fonts): Remove the leftover from old
1467 debugging code. Adjust comment style here and there.

1472 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1474 * w32.c (max_filename_mbslen): New function.
1475 (normalize_filename, readdir): Use it to detect locales where ANSI
1476 encoding of file names uses a double-byte character set (DBCS).
1477 If a DBCS encoding is used, advance by characters using
1478 CharNextExA, instead of incrementing a 'char *' pointer.
1479 Use _mbslwr instead of _strlwr. (Bug#13515)
1481 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1482 request of memory reservation to 1.7GB. (Bug#13065)
1484 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1486 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1487 at check_extra_latin label. (Bug#13505)
1489 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1491 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1492 Avoid redundant calls to strlen.
1494 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1496 Drop async_visible and async_iconified fields of struct frame.
1497 This is possible because async input is gone; for details, see
1498 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1499 * frame.h (struct frame): Remove async_visible and async_iconified
1500 members, convert garbaged to unsigned bitfield. Adjust comments.
1501 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1502 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1503 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1504 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1505 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1507 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1508 properly. Likewise for obscured.
1510 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1513 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1515 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1517 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1518 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1520 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1522 * xdisp.c (message2, message2_nolog): Remove functions.
1523 (message3, message3_nolog): Extract nbytes and multibyteness directly
1524 from the string. Change all callers.
1525 (message3_nolog): Don't set message_enable_multibyte since set_message
1526 will reset it anyway.
1527 (message1, message1_nolog): Use message3.
1528 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1529 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1530 (set_message): Drop all but the second arg, which has to be a string.
1531 (set_message_1): Simplify now that we know that a1 is NULL and the
1532 second arg is a string.
1533 * frame.h (struct frame): Remove `message_buf' field.
1534 Use glyphs_initialized_p instead.
1535 (FRAME_MESSAGE_BUF): Remove macro.
1536 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1537 * lisp.h (message2, message2_nolog): Remove declarations.
1538 (message3, message3_nolog): Update declarations.
1539 * keyboard.c (read_char_minibuf_menu_text)
1540 (read_char_minibuf_menu_width): Remove vars.
1541 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1542 to correctly handle multibyte strings.

1544 * editfns.c (message_text, message_length): Remove vars.
1545 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1546 * fileio.c (auto_save_error): Use message3 instead of message2.
1547 * dispnew.c (adjust_frame_message_buffer): Remove function.
1549 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1551 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1552 real estate used for the tool bar and the menu bar.
1554 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1556 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1557 hidden buffer is prepared to modification (Bug#13164).
1559 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1561 * window.h (struct window): Change window_end_valid member from
1562 Lisp_Object to a bitfield. Adjust comments.
1563 (wset_window_end_valid): Remove.
1564 * window.c (adjust_window_count): Clear window_end_valid.

1568 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1569 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1570 * xdisp.c (check_window_end, reconsider_clip_changes)
1571 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1572 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1573 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1575 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1577 * xdisp.c (mark_window_display_accurate): Simplify the loop
1578 assuming that the only one of vchild, hchild or buffer window
1579 slots is non-nil. Call mark_window_display_accurate_1 for
1580 the leaf windows only.
1581 (mark_window_display_accurate_1): Always assume leaf window.
1584 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1586 * emacs.c (Qkill_emacs_hook): Now static.
1588 * fileio.c (Finsert_file_contents): Simplify.
1589 Remove unnecessary assignments and tests.
1591 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1593 * w32.c (acl_set_file): Don't test for errors unless
1594 set_file_security returns FALSE. Avoids spurious errors when
1597 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1599 * fileio.c (Finsert_file_contents): Revert code introduced at
1600 2013-01-18 in favor of the simpler and generally better fix.
1601 Save stack space by removing 'buffer' and reusing 'read_buf'
1604 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1606 * lisp.h (eabs): Define unconditionally (Bug#13419).
1607 The old "#if !defined (eabs)" was an unnecessary revenant of back
1608 when this macro was called "abs". Document 'eabs' better.
1610 2013-01-19 Glenn Morris <rgm@gnu.org>
1612 * fns.c (Frandom): Doc fix.
1614 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1616 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1617 segfault when there are lots of overlays.
1619 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1620 when there are lots of overlays.
1621 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1622 for the details and a way to reproduce.
1624 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1626 * fileio.c: Use O_APPEND to append.
1627 This corresponds better to the natural interpretation of "append",
1628 and avoids the need to open the output file twice, or to invoke
1629 lseek when APPEND is neither nil nor a number.
1630 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1631 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1632 file possibly twice, and lseeking to its end; this avoids the
1633 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1634 at the same time: the combination is never needed and apparently
1635 it doesn't work with DOS_NT.
1637 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1638 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1640 Allow floating-point file offsets.
1641 Problem reported by Vitalie Spinu in
1642 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1643 * fileio.c (emacs_lseek): Remove.
1644 (file_offset): New function.
1645 (Finsert_file_contents, Fwrite_region): Use it.
1647 2013-01-19 Chong Yidong <cyd@gnu.org>
1649 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1650 aborting on Fsignal (Bug#13289).
1652 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1654 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1655 set_file_security as failure due to insufficient privileges.
1656 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1657 (fstat): Return owner and group like 'stat' and 'lstat' do.
1659 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1661 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1662 The bug was observed on Ubuntu operating inside a virtual machine,
1663 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1664 The workaround introduces a race condition on non-buggy hosts,
1665 but it's an unlikely race and anyway there's a nearly identical
1666 nearby race that can't be fixed.
1667 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1669 (Fwrite_region): Test for file system time stamp bug.
1670 (init_fileio): New function.
1671 * lisp.h (init_fileio): Declare it.
1672 * emacs.c (main): Call it.
1674 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1675 and make it more consistent with other stat-failure diagnostics.
1677 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1679 Fix crash when inserting data from non-regular files.
1680 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1681 for the error description produced by valgrind.
1682 * fileio.c (read_non_regular): Rename to read_contents.
1683 Free Lisp_Save_Value object used to pass parameters.
1684 (read_non_regular_quit): Rename to read_contents_quit.
1685 (Finsert_file_contents): Redesign internal file reading loop to adjust
1686 gap and end positions after each read and so help make_gap to work
1687 properly. Do not signal an I/O error too early and so do not leave
1688 not yet decoded characters in a buffer, which was the reason of
1689 redisplay crash. Use list2 to build return value. Adjust comments.
1691 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1693 Close a race when statting and reading files (Bug#13149).
1694 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1695 This avoids a race if the file is renamed between stat and open.
1696 This race is not the problem originally noted in Bug#13149;
1697 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1699 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

1706 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1707 * alloc.c (format_save_value): Rename to make_save_value.
1708 (make_save_pointer): New function.
1709 (record_xmalloc): Use make_save_pointer.
1710 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1711 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1712 Change users of make_save_value to make_save_pointer.

1729 (map_keymap_char_table_item): Adjust accordingly.
1730 * fileio.c (non_regular_fd, non_regular_inserted)
1731 (non_regular_nbytes): Remove.
1732 (Finsert_file_contents): Convert trytry to ptrdiff_t.
1733 Use format_save_value to pass parameters to read_non_regular.
1734 (read_non_regular): Use XSAVE_ macros to extract parameters.
1736 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
1738 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
1740 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
1742 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
1743 extraction from any Lisp_Save_Value slot. Add type checking.
1744 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
1745 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
1746 * xselect.c: All users changed.
1748 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

1761 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
1763 Avoid needless casts with XSAVE_POINTER.
1764 * alloc.c (mark_object) [GC_MARK_STACK]:
1765 * dired.c (directory_files_internal_unwind):
1766 * fileio.c (do_auto_save_unwind):
1767 * gtkutil.c (pop_down_dialog):
1768 * keymap.c (map_keymap_char_table_item):
1769 * lread.c (load_unwind):
1770 * nsmenu.m (pop_down_menu):
1771 * print.c (print_object) [GC_MARK_STACK]:
1772 * xfns.c (clean_up_file_dialog):
1773 * xmenu.c (cleanup_widget_value_tree):
1774 Omit casts between XSAVE_POINTER and a pointer type.
1776 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>

1779 * eval.c (eval_sub): Protect `form' from being GCed before its
1780 car and cdr becomes protected with the backtrace entry.

1790 (free_misc): Likewise.
1791 * alloc.c (allocate_misc): Now global.
1792 (free_misc): Likewise. Adjust comment.
1793 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
1794 (free_save_value): Likewise.
1795 (mark_object): Likewise.
1796 * editfns.c (save_excursion_save): Pack everything within
1797 Lisp_Save_Value and so avoid xmalloc.
1798 (save_excursion_restore): Adjust to match new layout. Use free_misc
1799 because we do not allocate extra memory any more. Add eassert.
1800 * print.c (print_object): New code to print Lisp_Save_Value. Do not
1801 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

1856 Problem and fix reported by Kazuhiro Ito.
1858 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>
1860 * insdel.c (Fcombine_after_change_execute, syms_of_insdel):

1871 Avoid unnecessary byte position calculation for the gap movement.
1872 Since all users of move_gap do CHAR_TO_BYTE for other purposes
1873 anyway, all of them should use move_gap_both instead.
1874 * lisp.h (move_gap): Remove prototype.
1875 * insdel.c (move_gap): Remove.
1876 (move_gap_both): Add eassert.

1882 emacsclient -t should not suspend Emacs server (Bug#13387)
1883 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
1885 * term.c (init_tty): Use them instead of rolling our own code.
1886 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
1887 switches from 'signal' to 'pthread_sigmask', which is safer in
1888 multithreaded applications.
1889 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
1890 which has already arranged for that.
1891 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
1892 This is the main part of the bug fix.

1904 predicate, which is how it's really used now. Adjust comment.
1905 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
1906 * buffer.c (buffer_slot_type_mismatch): Remove.
1907 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
1908 predicate. Adjust comment.

1911 left-margin-width, right-margin-width, left-fringe-width,
1912 right-fringe-width, scroll-bar-width and buffer-display-count.
1913 Use Qstringp for default-directory, buffer-file-name,
1914 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
1915 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
1917 * data.c (store_symval_forwarding): Adjust to call the predicate.

1933 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
1934 (make_gap_1): New function to adjust the gap of any buffer.
1935 * coding.c (coding_alloc_by_making_gap): Use it.
1936 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
1937 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
1939 2013-01-08 Juri Linkov <juri@jurta.org>

1953 2013-01-06 Chong Yidong <cyd@gnu.org>
1955 * keyboard.c (echo_add_char): New function, factored out from

1960 trailing dash is properly added.
1962 2013-01-05 Eli Zaretskii <eliz@gnu.org>
1964 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
1965 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
1966 digits for buffer positions, before misalignment starts.
1967 Display "0" for integer "object" field.
1968 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
1969 Display the newline glyph more unambiguously.
1971 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1973 * nsterm.m (ns_draw_underwave):
1974 * w32term.c (w32_draw_underwave):
1975 * xterm.c (x_draw_underwave): Make underwave look more triangular
1976 and also degrade gracefully for small fonts. (Bug#13000)
1978 * nsterm.m (ns_draw_text_decoration):
1979 * w32term.c (x_draw_glyph_string):
1980 * xterm.c (x_draw_glyph_string): Don't use previous underline
1981 thickness and position if previous underline type is underwave.
1983 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
1985 * fileio.c (Ffile_acl): Undocument return format.
1987 2013-01-02 Glenn Morris <rgm@gnu.org>
1989 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

1999 * lread.c (read_list):
2000 * minibuf.c (Ftry_completion):
2001 * term.c (tty_ins_del_lines):
2002 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2003 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2005 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2007 * w32.c (unsetenv): Set up the string passed to _putenv
2009 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
2010 for the bug this caused.
2012 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
2014 * coding.c (Qmac): Now static.
2016 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2018 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
2019 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

2023 (update_frame_tool_bar): Check toolbar_is_packed for packing.
2024 Show all on TOOLBAR_TOP_WIDGET.

2026 by TOOLBAR_TOP_WIDGET.
2027 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
2028 Check toolbar_is_packed.
2029 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on

2034 (xg_update_menubar): Update title only if
2035 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2036 (xg_update_submenu): Skip tearoff only if
2037 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2038 (xg_initialize): Initialize xg_detached_menus only if
2039 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2041 * xterm.h (struct x_output): Surround handlebox_widget with
2042 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2043 toolbar_in_hbox is bool.
2045 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2047 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2048 (LIBS_GNUSTEP): Define.
2049 (LIBES): Add $(LIBS_GNUSTEP).
2050 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
2052 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2054 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2055 continuation glyph on a TTY with an indication of an empty line.
2058 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2060 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2061 file's SELinux context or ACLs successfully set, nil otherwise.
2063 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
2065 * w32proc.c (reader_thread): Avoid passing NULL handles to
2066 SetEvent and WaitForSingleObject.
2068 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2070 Port EXTERNALLY_VISIBLE to Clang 3.2.
2071 * conf_post.h (__has_attribute): New macro.
2072 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2074 2012-12-27 Glenn Morris <rgm@gnu.org>
2076 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2077 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2079 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2081 * fileio.c (file_name_as_directory, directory_file_name):
2082 Accept an additional argument MULTIBYTE to indicate whether the input C
2083 came from a multibyte or a unibyte Lisp string; all callers
2084 adjusted. Don't assume the input string is always multibyte.
2086 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2087 don't ENCODE_FILE them, and return a unibyte string if the input
2089 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2090 don't assume the input strings will always be multibyte. If the
2091 input strings are multibyte, decode strings obtained from C
2094 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2096 * lisp.h (toplevel): Add two notices to the comment about
2097 defining a new Lisp data type.

2101 * alloc.c (valid_lisp_object_p): Adjust comment.
2103 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2105 * keyboard.c (record_asynch_buffer_change): Initialize an event
2106 only if it's really needed.
2107 * frame.h (enum output_method): Remove output_mac member since
2108 it's a leftover from the deleted code.
2109 * frame.c (Fframep): Adjust user here ...
2110 * terminal.c (Fterminal_live_p): ... and here.
2111 * coding.c (Qmac): Now here because it's only used to denote
2112 end-of-line encoding type.
2113 (syms_of_coding): DEFSYM it.
2114 * frame.h (Qmac): Remove duplicated declaration.
2116 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2118 * window.c (select_window_1): Now static, since it's used only here.
2120 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2122 * window.c (window_body_cols): Subtract display margins from the
2123 window body width on TTYs as well. See
2124 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2125 for the original report.
2127 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2129 * xdisp.c (redisplay_window): Remove inner local variable
2130 because the outer shadowed one has the same meaning.
2131 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2133 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2134 (xg_create_tool_bar): Adjust users.
2136 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2138 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2139 * buffer.c (Fget_buffer_create): Use it to set compact field of
2140 struct buffer_text to avoid accessing an uninitialized value
2141 when compact_buffer is called for the first time.
2142 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2143 (Fset_buffer_modified_p): Use buffer_window_count to check
2144 whether the buffer is displayed in some window.
2145 * xdisp.c (message_dolog): Likewise.
2147 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2149 * w32.c (acl_set_file): If setting the file security descriptor
2150 fails, and the new DACL is identical to the existing one, silently
2151 return success. This fixes problems for users backing up their
2152 own files without having the necessary privileges for setting
2153 security descriptors.
2155 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2157 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2158 after WaitForSingleObject returns normally. This expedites reader
2159 thread shutdown when delete_child triggers it.
2160 (reap_subprocess): More accurate commentary for why we call
2161 delete_child only when cp->fd is negative.
2163 * w32.c (sys_close): Do not call delete_child on a subprocess
2164 whose handle is not yet closed. Instead, set its file descriptor
2165 to a negative value, so that reap_subprocess will call
2166 delete_child on that subprocess when its SIGCHLD arrives.
2167 This avoids closing handles used for communications between sys_select
2168 and reader_thread, which doesn't give sys_select a chance to
2169 notice that the process exited and invoke the SIGCHLD handler for
2172 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2174 * nsfns.m (Fns_do_applescript): Run event loop until script has
2175 been executed (Bug#12969).
2176 (ns_run_ascript): Chech as_script for nil, set to nil after

2181 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2183 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2185 * w32term.c (w32fullscreen_hook): New function.
2186 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2188 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2190 * fileio.c (Finsert_file_contents): Doc fix.
2192 * w32proc.c (new_child, delete_child, find_child_pid): For a
2193 subprocess, consider its slot being in use as long as its process
2194 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2195 slot when a new process is started immediately after killing
2196 another one, without waiting enough time for the first process to
2197 be reaped and resources allocated for it be orderly freed.
2199 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2201 2012-12-21 Chong Yidong <cyd@gnu.org>
2203 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2205 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2207 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2209 * w32.c (get_name_and_id): Always pass NULL as the first argument
2210 of lookup_account_sid. Avoids crashes with UNC file names that
2211 refer to DFS domains, not to specific machine names. (Bug#12621)
2212 Remove now unused argument FNAME; all callers changed.
2213 (get_file_owner_and_group): Remove now unused argument FNAME; all
2216 2012-12-21 Chong Yidong <cyd@gnu.org>
2218 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2219 error for invalid chars, don't check for a nil return value.
2221 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2223 Avoid calls to CHAR_TO_BYTE if byte position is known.
2224 * editfns.c (make_buffer_string_both): Use move_gap_both.
2225 (Fbuffer_string): Use make_buffer_string_both.
2226 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2228 (buf_bytepos_to_charpos): Likewise.
2229 (charpos_to_bytepos): Remove.
2230 * fileio.c (Finsert_file_contents): Use move_gap_both.
2231 * search.c (Freplace_match): Likewise.
2232 * process.c (process_send_region): Likewise. Use convenient
2233 names for byte positions.
2234 * lisp.h (charpos_to_bytepos): Remove prototype.
2235 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2236 * insdel.c (move_gap): Likewise.
2238 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2240 * xdisp.c (redisplay_internal): Remove now-unused local.
2242 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2244 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2245 (redisplay_internal): Don't bother selecting the frame to get the
2246 proper value of frame-local variables (bug#13225).
2248 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2250 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2251 Rename 4th argument since it may be buffer or string. Adjust comment.
2252 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2254 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2256 * coding.c (Fdetect_coding_region): Do not check start and end with
2257 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2258 (code_convert_region): Likewise.
2260 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2262 * w32.c (acl_get_file, acl_set_file): Run the file name through
2263 map_w32_filename, and resolve any symlinks in the file name, like
2265 (acl_set_file): Call revert_to_self, if any privileges were
2268 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2270 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2271 ($(BLD)/w32.$(O)): Update dependencies.
2273 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2275 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2276 propagate redisplay's scrolling (if any) to the right window.
2277 (redisplay_internal): Use ensure_selected_frame.
2278 (display_mode_lines): Complete last fix.
2279 * window.c (select_window_1): New func, extracted from select_window.
2280 (select_window): Use it.
2281 * window.h (select_window_1): Declare.
2283 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2285 Emulate Posix ACL APIs on MS-Windows.
2286 * w32.c: Include sddl.h and sys/acl.h.
2287 (SDDL_REVISION_1): Define if not already defined.

2307 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2309 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2310 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2311 for some of that bug's symptoms can now cause Emacs to abort.
2312 Remove the workaround.
2313 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2314 The bug that caused SIGCHLD to get lost has been fixed, and the
2315 workaround for it can now cause Emacs to abort.
2317 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2319 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2320 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in

2325 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2326 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2327 and copy ACL entries of file in addition to SELinux context if set.
2328 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2330 * Makefile.in (LIBACL_LIBS): New macro.
2333 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
2335 * fileio.c (internal_delete_file): Use bool for boolean.
2337 2012-12-15 Eli Zaretskii <eliz@gnu.org>
2339 Fix bug #13079 on MS-Windows with temp files not being deleted.
2340 * w32.h (_child_process): New members input_file and
2342 (register_child): First argument is now pid_t.
2343 (record_infile, record_pending_deletion): New prototypes.
2345 * w32proc.c (new_child): Initialize input_file and
2346 pending_deletion members of the child.
2347 (delete_child): Delete the child's temporary input file, if any,
2348 that is pending deletion.
2349 (register_child): First argument is now pid_t.
2350 (record_infile, record_pending_deletion): New functions.
2351 (reap_subprocess): Fix a typo in DebPrint string.
2352 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2354 * fileio.c (internal_delete_file): Return an int again: non-zero
2355 if delete-file succeeds, zero otherwise.
2357 * lisp.h (internal_delete_file): Adjust prototype.
2359 * callproc.c (Fcall_process): Don't overwrite infile with result
2361 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2362 asynchronous subprocess, record the name of the input file name,
2364 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2365 delete the file, record it as pending deletion when the subprocess
2368 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2370 * editfns.c [HAVE_PWD_H]: Include grp.h.
2372 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.

2376 Fix permissions bugs with setgid directories etc. (Bug#13125)
2377 * dired.c (Ffile_attributes): Return t as the 9th attribute,
2378 to mark it as a placeholder. The old value was often wrong.
2379 The only user of this attribute has been changed to use
2380 file-ownership-preserved-p instead, with its new group arg.
2381 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
2383 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

2388 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2390 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2391 try to get accurate owner and group information from NT file
2392 security APIs. This is to make most callers of 'stat' and
2393 'lstat', which don't need that information, much faster.
2395 * dired.c (Ffile_attributes) [WINDOWSNT]:
2396 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2397 owner and group information from 'lstat'.
2399 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2401 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2402 as that confuses set-auto-coding, so insist on the head-read
2403 returning the full 1024 bytes. Let lseek compute the tail offset;
2404 less work for us. Do not ignore I/O errors when reading the tail.
2406 * xdisp.c: Minor style fixes.
2407 (init_iterator): Hoist assignment out of if-expression.
2408 (markpos_of_region): Callers now test for sign, not for -1.

2425 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2427 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2428 files, fixing a regression from 24.2.
2429 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2431 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2433 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2434 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2435 Remove unnecessary S_ISLNK test, as (contra the comments) this
2436 function can't copy symlinks. Improve quality of error message
2437 when attempting to copy files that are neither regular files nor

2444 * window.c (Frecenter):
2445 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
2446 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
2448 2012-12-12 Daniel Colascione <dancol@dancol.org>
2450 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2451 the dumped Emacs is not a sparse file, greatly improving Cygwin
2452 "make bootstrap" performance.
2454 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
2456 * inotify.c (inotify_callback): Generate an Emacs event for every
2457 incoming inotify event.
2459 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2461 * xdisp.c (handle_face_prop): Fix logic of computing
2462 it->start_of_box_run_p.
2463 (append_space_for_newline): If the glyph row is R2L, reset the
2464 iterator's end_of_box_run_p flag before prepending the space glyph.
2465 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2466 iterator's start_of_box_run_p flag before prepending the stretch.

2468 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2469 left_box_line_p and right_box_line_p flags of the glyph for R2L
2470 glyph rows. (Bug#13011)

2484 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
2485 encoded_file_name, which is what it is.
2487 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

2516 * w32fns.c (cache_system_info): Initialize the global hinst
2517 variable here so various initialization calls DTRT.
2519 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
2520 (hinst): Remove unneeded extern declaration.
2521 (_start): Remove initialization of above variables; remove
2522 initialization of hinst, as cache_system_info now does that.

2741 * frame.c (make_frame): Do not set window's buffer to t.
2742 * window.c (Fsplit_window_internal): Likewise. Previously it was
2743 used to indicate that the window is being set up. Now we use

2745 (Fset_window_buffer): ... is always true and can be removed.
2747 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2749 Convenient macro to check whether the buffer is hidden.

2761 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2763 * frame.h (x_char_width, x_char_height): Remove prototypes.

2777 * callproc.c, process.h (record_kill_process):
2778 New function, containing part of the old call_process_kill.
2779 (call_process_kill): Use it.
2780 This does not change call_process_kill's behavior.
2781 * process.c (Fdelete_process): Use record_kill_process to fix a
2782 race condition that could cause Emacs to lose track of a child.
2784 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2786 Avoid code duplication between prev_frame and next_frame.
2787 * frame.c (candidate_frame): New function. Add comment.

2790 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2792 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2793 fails, signal an error instead of continuing with an empty
2795 Encode expanded temp file pattern before passing it to mkstemp or
2798 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2799 Encode the file name before passing it to dostounix_filename, in
2800 case it will downcase it (under w32-downcase-file-names).
2803 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2805 Minor call-process cleanups.
2806 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2807 at the same time as other platforms, to simplify analysis.
2808 No need for fd0_volatile since we have synch_process_fd.
2809 Avoid needless emacs_close; arg is always negative.
2811 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2813 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2816 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2818 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2819 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2820 and mouse_face_hidden members to a bitfields.
2821 * frame.h (struct frame): Remove set-but-not-used space_width member.
2822 (FRAME_SPACE_WIDTH): Remove.
2823 * nsterm.m, w32term.c, xterm.c: Adjust users.
2824 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2825 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2826 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2827 members to a bitfields.
2829 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2831 Don't let call-process be a zombie factory (Bug#12980).
2832 Fixing this bug required some cleanup of the signal-handling code.
2833 As a side effect, this change also fixes a longstanding rare race
2834 condition whereby Emacs could mistakenly kill unrelated processes,
2835 and it fixes a bug where a second C-g does not kill a recalcitrant
2836 synchronous process in GNU/Linux and similar platforms.
2837 The patch should also fix the last vestiges of Bug#9488,
2838 a bug which has mostly been fixed on the trunk by other changes.
2839 * callproc.c, process.h (synch_process_alive, synch_process_death)
2840 (synch_process_termsig, sync_process_retcode):
2841 Remove. All uses removed, to simplify analysis and so that
2842 less consing is done inside critical sections.
2843 * callproc.c (call_process_exited): Remove. All uses replaced
2844 with !synch_process_pid.
2845 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2846 These take the role of what used to be in unwind-protect arg.
2848 (block_child_signal, unblock_child_signal):
2849 New functions, to avoid races that could kill innocent-victim processes.
2850 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2851 (call_process_kill): Record killed processes as deleted, so that
2852 zombies do not clutter up the system. Do this inside a critical
2853 section, to avoid a race that would allow the clutter.
2854 (call_process_cleanup): Fix code so that the second C-g works again
2855 on common platforms such as GNU/Linux.
2856 (Fcall_process): Create the child process in a critical section,
2857 to fix a race condition. If creating an asynchronous process,
2858 record it as deleted so that zombies do not clutter up the system.
2859 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2860 light of these changes. Omit unnecessary call to emacs_close
2861 before failure, as the unwind-protect code does that.
2862 * callproc.c (call_process_cleanup):
2863 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2864 * process.c (record_deleted_pid): New function, containing
2865 code refactored out of Fdelete_process.
2866 (Fdelete_process): Use it.
2867 (process_status_retrieved): Remove. All callers changed to use
2868 child_status_change.
2869 (record_child_status_change): Remove, folding its contents into ...
2870 (handle_child_signal): ... this signal handler. Now, this
2871 function is purely a handler for SIGCHLD, and is not called after
2872 a synchronous waitpid returns; the synchronous code is moved to
2873 wait_for_termination. There is no need to worry about reaping
2874 more than one child now.
2875 * sysdep.c (get_child_status, child_status_changed): New functions.
2876 (wait_for_termination): Now takes int * status and bool
2877 interruptible arguments, too. Do not record child status change;
2878 that's now the caller's responsibility. All callers changed.
2879 Reimplement in terms of get_child_status.
2880 (wait_for_termination_1, interruptible_wait_for_termination):
2881 Remove. All callers changed to use wait_for_termination.
2882 * syswait.h: Include <stdbool.h>, for bool.
2883 (record_child_status_change, interruptible_wait_for_termination):
2885 (record_deleted_pid, child_status_changed): New decls.
2886 (wait_for_termination): Adjust to API changes noted above.
2888 * bytecode.c, lisp.h (Qbytecode): Remove.
2889 No longer needed after 2012-11-20 interactive-p changes.
2891 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2893 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2894 the scroll margin, move point outside the margin. (Bug#13055)
2896 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2898 * gtkutil.c (my_log_handler): New function.
2899 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2901 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2903 * lisp.h (modify_region): Rename to...
2904 (modify_region_1): ...new prototype.
2905 * textprop.c (modify_region): Now static. Adjust users.
2906 * insdel.c (modify_region): Rename to...
2907 (modify_region_1): ...new function to work with current buffer.
2908 Adjust comment and users. Use true and false for booleans.
2910 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2912 * alloc.c (free_save_value): New function.
2913 (safe_alloca_unwind): Use it.
2914 * lisp.h (free_save_value): New prototype.
2915 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2917 (save_excursion_restore): Adjust to match saved data structure.
2918 Use free_save_value to offload some work from GC. Drop obsolete
2921 2012-12-03 Chong Yidong <cyd@gnu.org>
2923 * fileio.c (Vauto_save_list_file_name): Doc fix.
2925 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2927 * w32fns.c: Remove prototype of atof.
2928 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2930 (file_dialog_callback): Make it UINT_PTR.
2932 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2935 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2936 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2939 2012-12-03 Glenn Morris <rgm@gnu.org>
2941 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2943 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2945 Fix xpalloc confusion after memory is exhausted.
2946 * alloc.c (xpalloc): Comment fix.
2947 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2948 and signals an error, do not clear charset_table_size, as
2949 charset_table is still valid.
2950 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2952 Use execve to avoid need to munge environ (Bug#13054).
2953 * callproc.c (Fcall_process):
2954 * process.c (create_process):
2955 Don't save and restore environ; no longer needed.
2956 * callproc.c (child_setup):
2957 Use execve, not execvp, to preserve environ.
2959 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2961 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2963 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2965 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2966 display for sliced images (Bug#10500).
2968 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
2970 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2972 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2973 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2975 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2977 * xdisp.c (window_outdated): Remove eassert since it hits
2978 some suspicious corner cases (see Bug#13007 and Bug#13012).
2979 (mode_line_update_needed): New function.
2980 (redisplay_internal, redisplay_window): Use it.
2981 (ensure_selected_frame): New function.
2982 (redisplay_internal, unwind_redisplay): Use it.
2983 (redisplay_internal): Move comment about buffer_shared...
2984 (buffer_shared_and_changed): ...near to its real use.
2986 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2988 * callproc.c (Fcall_process): Don't misreport vfork failure.
2990 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2992 * callproc.c (Fcall_process): Fix vfork portability problems.
2993 Do not assume that fd[0], count, filefd, and save_environ survive
2994 vfork. Fix bug whereby wrong errno value could be reported for
2995 pipe failure. Some minor cleanups, too, as follows. Move buf and
2996 bufsize to the context where they're needed. Change new_argv to
2997 be of type char **, as this is more convenient and avoids casts.
2998 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2999 Now local constants, not macros.
3001 2012-11-18 Kenichi Handa <handa@gnu.org>
3003 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3004 for the variable "f".
3006 2012-11-13 Kenichi Handa <handa@gnu.org>
3008 * font.c (font_unparse_xlfd): Exclude special characters from the
3009 generating XLFD name.
3011 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

3035 highlighting on the frame was cleared. Prevents assertion
3036 violations when repeatedly clicking on the "Top" link of the
3037 "bread-crumbs" in Info buffers.

3051 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3052 between bpos_covered and bpos_max. This fixes cursor display when
3053 several display strings follow each other.
3055 * .gdbinit (pgx): If the glyph's object is a string, display the
3056 pointer to string data, rather than the value of the string object
3057 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3059 * indent.c (Fvertical_motion): If the starting position is covered
3060 by a display string, return to one position before that, to avoid
3061 overshooting it inside move_it_to. (Bug#12930)

3082 of a literal "/". (Bug#12955)
3083 (gl-stamp): Invoke fc.exe directly, not through cmd.

3088 * dired.c: Assume HAVE_DIRENT_H.
3089 (NAMLEN): Remove, replacing with ...
3090 (dirent_namelen): New function. All uses changed. Use the GNU macro
3091 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3092 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3093 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3094 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3096 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3097 * ndir.h: Rename to ../nt/inc/dirent.h.
3098 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3099 Do not include <dirent.h>; no longer needed.
3100 * w32.c: Include <dirent.h> rather than "ndir.h".
3102 2012-11-23 Chong Yidong <cyd@gnu.org>
3104 * xftfont.c (xftfont_open): Remove duplicate assignment.
3106 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3108 * alloc.c (Fgarbage_collect): Unblock input after clearing
3109 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3110 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3111 * msdos.c (IT_frame_up_to_date): Use it here...
3112 * w32term.c (w32_frame_up_to_date): ...here...
3113 * xterm.c (XTframe_up_to_date): ...and here...
3114 * nsterm.m (ns_frame_up_to_date): ...but not here.

3128 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3130 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts

3154 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3156 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3158 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3159 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3160 Define for the MSVC compiler.
3162 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3164 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3165 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to

3167 dostounix_filename assumes it gets a unibyte string.
3168 Reported by Michel de Ruiter <michel@sentient.nl>, see

3217 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3219 * w32select.c: Include w32common.h before w32term.h, so that
3220 windows.h gets included before w32term.h uses some of its
3221 features, see below.
3223 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3225 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

3239 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3241 * w32proc.c (waitpid): Remove unused label get_result.

3253 * emacs.c, term.c (O_RDWR): Remove.
3254 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3255 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3256 * nsterm.m: Assume <fcntl.h> exists.
3257 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3258 (create_pty, Fmake_network_process, server_accept_connection)
3259 (wait_reading_process_output, init_process_emacs):
3261 (wait_reading_process_output): Put in a special case for WINDOWSNT
3262 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3263 It's not clear this is needed, but it's a more-conservative change.
3264 (create_process): Assume FD_CLOEXEC.
3265 (create_process, create_pty): Assume O_NOCTTY.
3266 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3267 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3268 Omit if not DOS_NT, since F_GETFL is not defined there.
3269 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3270 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3272 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3273 lack it, since gnulib guarantees this.
3274 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3276 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3278 * w32.c (faccessat): Pretend that directories have the execute bit
3279 set. Emacs expects that, e.g., in files.el:cd-absolute.
3281 * w32proc.c (create_child): Don't clip the PID of the child
3282 process to fit into an Emacs integer, as this is no longer a
3284 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3285 reaping only the process specified by PID argument, if that is
3286 positive. Use PID instead of dead_child to know which process to
3287 reap. Wait for the child to die only if WNOHANG is not in
3289 (sys_select): Don't set dead_child.
3291 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3292 as it is no longer needed.
3294 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3296 (record_child_status_change): Remove the setting of
3297 record_at_most_one_child for the !WNOHANG case.
3299 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3301 Fix problems in ns port found by static checking.
3302 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3303 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3304 not to process group.
3305 (ns_select): Use emacs_write, not write, as that's more robust
3306 in the presence of signals.
3307 (fd_handler:): Check for read errors.
3309 2012-11-16 Glenn Morris <rgm@gnu.org>
3311 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3313 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3315 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3317 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3319 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3320 use the same value of thread handle.
3321 (start_timer_thread): If the timer thread exited (due to error),
3322 clean up by closing the two handles it used. Duplicate the caller
3323 thread's handle here, so it gets duplicated only once, when
3324 launching the timer thread. Set priority of the timer thread, not
3326 (getitimer): Don't duplicate the caller thread's handle here.
3329 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3331 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3334 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3336 Remove no-longer-used pty_max_bytes variable.
3337 * process.c (pty_max_bytes): Remove; unused.
3338 (send_process): Do not set it.
3340 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3342 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3343 Update dependencies.
3345 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3347 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3348 This follows up on the 2012-09-29 patch that removed indirection
3349 for the 'function' field. Reported by Sergey Vinokurov in
3350 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3352 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3354 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3355 different name, as the MS runtime does not have such a function,
3356 and probably never will.) All callers changed. Ignore DIRFD
3357 value if PATH is an absolute file name, to match Posix spec
3358 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3361 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3363 * xdisp.c (echo_area_display, redisplay_internal):
3364 Omit redundant check whether frame_garbaged is set.
3366 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3368 Use faccessat, not access, when checking file permissions (Bug#12632).
3369 This fixes a bug that has been present in Emacs since its creation.
3370 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3371 which must set some sort of record. (Torek's bug report was against
3372 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3373 same common flaw.) See Torek's Usenet posting
3374 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3375 Posted: Fri Apr 8 14:18:56 1983.
3376 * Makefile.in (LIB_EACCESS): New macro.
3378 * callproc.c (init_callproc):
3379 * charset.c (init_charset):
3380 * fileio.c (check_existing, check_executable, check_writable)
3382 * lread.c (openp, load_path_check):
3383 * process.c (allocate_pty):
3385 Use effective UID when checking permissions, not real UID.
3386 * callproc.c (init_callproc):
3387 * charset.c (init_charset):
3388 * lread.c (load_path_check, init_lread):
3389 Test whether directories are accessible, not merely whether they exist.
3390 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3391 * fileio.c (check_existing, check_executable, check_writable)
3393 Use symbolic names instead of integers for the flags, as they're
3395 (check_writable): New arg AMODE. All uses changed.
3396 Set errno on failure.
3397 (Ffile_readable_p): Use faccessat, not stat + open + close.
3398 (Ffile_writable_p): No need to call check_existing + check_writable.
3399 Just call check_writable and then look at errno. This saves a syscall.
3400 dir should never be nil; replace an unnecessary runtime check
3401 with an eassert. When checking the parent directory of a nonexistent
3402 file, check that the directory is searchable as well as writable, as
3403 we can't create files in unsearchable directories.
3404 (file_directory_p): New function, which uses 'stat' on most platforms
3405 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3406 (Ffile_directory_p, Fset_file_times): Use it.
3407 (file_accessible_directory_p): New function, which uses a single
3408 syscall for efficiency.
3409 (Ffile_accessible_directory_p): Use it.
3410 * xrdb.c (file_p): Use file_directory_p.
3411 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3412 * lread.c (openp): When opening a file, use fstat rather than
3413 stat, as that avoids a permissions race. When not opening a file,
3414 use file_directory_p rather than stat.
3415 (dir_warning): First arg is now a usage string, not a format.
3416 Use errno. All uses changed.
3417 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3418 that merely introduced a race.
3419 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3420 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3421 and similarly for the other O_* flags.
3422 * w32.c (sys_faccessat): Rename from sys_access and switch to
3423 faccessat's API. All uses changed.
3424 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3425 (magic_db): Rename from magic_file_p.
3426 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3427 char *, so that we don't have to test for file existence
3428 separately from opening the file for reading. This removes a race
3429 fixes a permission-checking problem, and simplifies the code.
3431 (file_p): Remove; no longer needed.
3433 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3435 Omit glyphs initialization at startup.
3436 * dispnew.c (glyphs_initialized_initially_p): Remove.
3437 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3438 (Fredraw_frame): Move actual code from here...
3439 (redraw_frame): ...to here. Add eassert. Adjust comment.
3440 (Fredraw_display): Use redraw_frame.
3441 * xdisp.c (clear_garbaged_frames): Likewise.
3443 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3445 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3446 passed to pint2str and pint2hrstr to be at most the size of the
3447 frame's decode_mode_spec_buffer. This avoids crashes with very
3448 large values of FIELD_WIDTH argument to decode_mode_spec.
3451 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3453 Fix a race with verify-visited-file-modtime (Bug#12863).
3454 Since at least 1991 Emacs has ignored an mtime difference of no
3455 more than one second, but my guess is that this was to work around
3456 file system bugs that were fixed long ago. Since the race is
3457 causing problems now, let's remove that code.
3458 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3459 whose time stamp is off by no more than a second. Insist that the
3460 file time stamps match exactly.
3462 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3464 * frame.h (struct frame): Convert external_tool_bar member to
3465 1-bit unsigned bitfield.
3466 * termhooks.h (struct terminal): Remove mouse_moved member since
3467 all users are long dead. Adjust comment on mouse_position_hook.
3469 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3471 Simplify by using FOR_EACH_FRAME here and there.
3472 * frame.c (next_frame, prev_frame, other_visible_frames)
3473 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3474 * w32term.c (x_window_to_scroll_bar): Likewise.
3475 * window.c (window_list): Likewise.
3476 * xdisp.c (x_consider_frame_title): Likewise.
3477 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3478 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3479 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3480 * xmenu.c (menubar_id_to_frame): Likewise.
3481 * xselect.c (frame_for_x_selection): Likewise.
3482 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3483 (x_window_to_menu_bar): Likewise.
3484 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3486 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3488 * data.c (Qdefalias_fset_function): Now static.
3490 Another tweak to vectorlike_header change.
3491 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3492 Remove, and replace all uses with ...
3493 (next_in_free_list, set_next_in_free_list):
3494 New functions, which respect C's aliasing rules better.
3496 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3498 * window.c (list4i): Rename from 'quad'. All uses changed.
3499 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3501 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3503 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3504 warning about mixing declarations and code in ISO C90.
3506 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3508 * window.c (Fsplit_window_internal): Set combination limit of
3509 new parent window to t iff Vwindow_combination_limit is t;
3510 fixing a regression introduced with the change from 2012-09-22.
3511 (Fset_window_combination_limit): Fix doc-string.
3513 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3515 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3516 amount when the scroll margins are too large. When scrolling
3517 backwards in the buffer, give up if cannot reach point or the
3518 scroll margin within a reasonable number of screen lines.
3519 Fixes point position in window under scroll-up/down-aggressively when
3520 point is positioned many lines beyond the window top/bottom.
3523 * ralloc.c (relinquish): If real_morecore fails to return memory
3524 to the system, don't crash; instead, leave the last heap
3525 unchanged and return. (Bug#12774)
3527 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3529 * lisp.h (AUTOLOADP): New macro.
3530 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3531 * data.c (Ffset): Remove special ad-advice-info handling.
3532 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3534 (Finteractive_form): Simplify.
3535 (Fquo): Don't insist on having at least 2 arguments.
3536 (Qdefalias_fset_function): New var.
3538 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3540 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
3542 * nsfont.m (Qcondensed, Qexpanded): New variables.
3543 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
3544 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3546 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3548 Fix recently introduced crash on MS-Windows (Bug#12839).
3549 * w32term.h (struct scroll_bar): Use convenient header.
3550 (SCROLL_BAR_VEC_SIZE): Remove.
3551 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3553 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3555 Tweak last vectorlike_header change.
3556 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3557 vectorlike object on the free list. This is introduced to avoid
3558 some (but not all) pointer casting and aliasing problems, see
3559 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3560 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3562 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3564 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3566 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3567 been removed, so remove them here also.
3569 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3571 * doc.c (Fdocumentation): Handle new property
3572 dynamic-docstring-function to replace the old ad-advice-info.
3574 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3576 * fns.c (Qeql, hashtest_eq): Now static.
3578 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3580 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3581 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3582 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
3583 * buffer.c (compare_overlays): Use XLI rather than XHASH.
3585 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
3587 Use same hash function for hashfn_profiler as for hash_string etc.
3588 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3589 * lisp.h (sxhash_combine): New inline function, with the contents
3590 of the old SXHASH_COMBINE.
3591 * profiler.c (hashfn_profiler): Use it, instead of having a
3592 special hash function containing a comparison that always yields 1.
3594 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3596 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3597 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3598 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3601 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3603 * image.c (xpm_make_color_table_h): Fix compiler error because
3604 make_hash_table changed.
3606 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3608 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3610 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3612 Use ad-hoc comparison function for the profiler's hash-tables.
3613 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3614 (make_log): Use them.
3615 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3616 call Fequal any more.

3625 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3626 (hash_lookup, hash_remove_from_table): Move assertion checking of
3627 hashfn result here. Check hash-equality before calling cmpfn.
3628 (Fmake_hash_table): Adjust call to make_hash_table.
3629 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
3630 (syms_of_fns): Initialize them.

3637 2012-11-08 Eli Zaretskii <eliz@gnu.org>
3639 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3640 value of w32-scroll-lock-modifier is neither nil nor one of the
3641 known key modifiers. (Bug#12806)
3643 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3645 Shrink struct vectorlike_header to the only size field.
3646 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3648 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3649 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3650 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3651 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3652 information from the vector header. Adjust comment.
3653 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
3654 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
3656 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
3657 (struct vectorlike_header): Remove next member. Adjust comment.

3662 (enum mem_type): Adjust comment.
3663 (NEXT_IN_FREE_LIST): New macro.
3664 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3665 (Fmake_bool_vector): Likewise.
3666 (struct large_vector): New type to represent allocation unit for
3667 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3668 (large_vectors): Change type to struct large_vector.
3669 (allocate_vector_from_block): Simplify.
3670 (PSEUDOVECTOR_NBYTES): Replace with...
3671 (vector_nbytes): ...new function. Adjust users.
3672 (sweep_vectors): Adjust processing of large vectors.
3673 (allocate_vectorlike): Likewise.
3674 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3675 Add easserts. Adjust XSETPVECTYPESIZE usage.
3676 (allocate_buffer): Use BUFFER_PVEC_INIT.
3677 (live_vector_p): Adjust to match large vector.
3678 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3679 * buffer.h (struct buffer): Add next member.
3680 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
3682 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
3683 * fns.c (internal_equal): Adjust to match enum pvec_type change.
3684 (copy_hash_table): Adjust to match vector header change.
3685 * lread.c (defsubr): Use XSETPVECTYPE.
3686 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
3687 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
3688 (xvecsize): New command.
3690 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3692 * keyboard.c (event_to_kboard): Do not dereference
3693 frame_or_window field of SELECTION_REQUEST_EVENT
3694 and SELECTION_CLEAR_EVENT events (Bug#12814).
3695 * xterm.h (struct selection_input_event): Adjust comment.
3697 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3699 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3700 such as Scroll Lock, if the respective keys are treated as
3701 function keys, not as modifiers. This avoids destroying non-ASCII
3702 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3704 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3706 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3708 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3710 Restore some duplicate definitions (Bug#12814).
3711 This undoes part of the 2012-11-03 changes. Some people build
3712 with plain -g rather than with -g3, and they need the duplicate
3713 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3714 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3715 Define as macros, as well as as enums or as constants.
3717 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3719 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3720 to keypad keys (Bug#12816).
3722 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3724 Minor adjustments of recently-changed frame functions.
3725 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3726 known to be a frame (we're in the FRAMEP branch).
3727 * lisp.h (Qframep): Remove decl. frame.h declares this.
3728 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3729 since they're meant for Lisp fixnum values.
3731 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3733 * window.c (Fwindow_combination_limit): Revert to the only
3734 required argument and adjust docstring as suggested in
3735 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3736 by Martin Rudalics <rudalics@gmx.at>.
3738 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3740 Widely used frame validity and checking functions.
3741 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3742 * frame.c (decode_live_frame, decode_any_frame): New functions.
3743 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3744 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3745 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3746 (Fframe_pointer_visible_p): Use decode_any_frame.

3748 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
3749 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3750 (Fframe_focus): Likewise. Allow zero number of arguments.
3752 (frame_buffer_list, frame_buffer_predicate): Remove.
3753 * lisp.h (frame_buffer_predicate): Remove prototype.
3754 * buffer.c (Fother_buffer): Use decode_any_frame.
3755 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3756 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3757 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3758 (Fclose_font, Ffont_info): Use decode_live_frame.
3759 * fontset.c (check_fontset_name): Likewise.
3760 * terminal.c (Fframe_terminal): Likewise.
3761 * w32fns.c (check_x_frame): Likewise.
3762 * window.c (Fminibuffer_window, Fwindow_at)
3763 (Fcurrent_window_configuration): Likewise.
3764 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3765 Likewise. Allow zero number of arguments. Adjust docstring.
3766 * dispnew.c (Fredraw_frame): Likewise.
3767 * xfaces.c (frame_or_selected_frame): Remove.
3768 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3769 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3770 (Fframe_face_alist): Use decode_live_frame.
3771 * xfns.c (check_x_frame): Likewise.
3773 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3775 * window.c (quad): New function.
3776 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3777 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3778 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3779 (Fwindow_line_height): Use it.
3780 (Fwindow_fringes): Use list3.
3781 (Fwindow_scroll_bars): Use list4.
3782 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3783 (Fwindow_combination_limit): Allow zero number of arguments.
3785 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3787 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3789 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3790 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3791 file descriptor 2 for standard error. (Bug#12805)
3793 2012-11-05 Chong Yidong <cyd@gnu.org>
3795 * process.c (wait_reading_process_output): Revert previous change.
3797 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3799 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3800 This removes code that has been obsolete since around 1990.
3801 * callproc.c (Fcall_process):
3803 * process.c (create_process):
3804 * term.c (dissociate_if_controlling_tty):
3805 Assume setsid exists.
3806 * callproc.c (child_setup): Assume setpgid exists and behaves as
3807 per POSIX.1-1988 or later.
3808 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3809 * emacs.c (shut_down_emacs):
3810 * sysdep.c (sys_suspend, init_foreground_group):
3811 Assume getpgrp behaves as per POSIX.1-1998 or later.
3812 * msdos.c (setpgrp): Remove.
3813 (tcgetpgrp, setpgid, setsid): New functions.
3814 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3815 * term.c (no_controlling_tty): Remove; unused.
3816 * w32proc.c (setpgrp): Remove.
3817 (setsid, tcgetpgrp): New functions.
3819 Simplify by assuming __fpending.
3820 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3821 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3822 Do not assume that __fpending's result fits in int.
3824 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3826 Remove EMACS_OUTQSIZE+sleep hack.
3827 * dispnew.c (update_frame_1): Remove hack for terminals slower
3828 than 2400 bps, which throttled Emacs by having it sleep.
3829 This code hasn't worked since at least 2007, when the multi-tty stuff
3830 was added, and anyway those old terminals are long dead.
3831 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3832 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3834 Fix data-loss with --version (Bug#9574).
3835 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3836 as we can't assume that emacs_strerror is initialized, and strerror
3837 is good enough here.
3838 (main): Invoke atexit earlier, to catch earlier instances of
3839 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3841 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3843 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3844 (keyDown): Remap keypad keys to X11 virtual key codes.
3846 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3848 Fix data-loss with --batch (Bug#9574).
3849 * emacs.c: Include <close-stream.h>.
3850 (close_output_streams): New function.
3851 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3852 and handles errors appropriately.
3853 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3856 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3857 The symptom is a diagnostic "GLib-WARNING **: In call to
3858 g_spawn_sync(), exit status of a child process was requested but
3859 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3860 waitpid(), so exit status can't be returned." The diagnostic
3861 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3862 The real bug is a race condition between Emacs and glib: Emacs
3863 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3864 so that glib can't find it. Work around the bug by invoking
3865 waitpid only on subprocesses that Emacs itself creates.
3866 * process.c (create_process, record_child_status_change):
3867 Don't use special value -1 in pid field, as the caller now must
3868 know the pid rather than having the callee infer it.
3869 The inference was sometimes incorrect anyway, due to another race.
3870 (create_process): Set new 'alive' member if child is created.
3871 (process_status_retrieved): New function.
3872 (record_child_status_change): Use it.
3873 Accept negative 1st argument, which means to wait for the
3874 processes that Emacs already knows about. Move special-case code
3875 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3876 processes that have already been waited for, by testing and
3877 clearing new 'alive' member.
3878 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3879 now does this internally.
3880 (handle_child_signal): Let record_child_status_change do all
3881 the work, since we do not want to reap all exited child processes,
3882 only the child processes that Emacs itself created.
3883 * process.h (Lisp_Process): New boolean member 'alive'.
3885 Omit duplicate definitions no longer needed with gcc -g3.
3886 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3887 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3888 Define only as macros. There's no longer any need to also define
3889 these symbols as enums or as constants, since we now assume
3890 gcc -g3 when debugging.
3892 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3894 * lisp.mk: Adjust comments to the fact that term/internal is now
3895 loaded from loadup.el.
3897 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3898 (msdos_fatal_signal): New function.
3899 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3902 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3903 for GCC versions before 4.
3904 (emacs_raise): Define to call msdos_fatal_signal.
3906 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3907 iterator when starting in the middle of a display or overlay
3910 2012-11-03 Chong Yidong <cyd@gnu.org>
3912 * process.c (wait_reading_process_output): Clean up the last
3915 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3917 * process.c (wait_reading_process_output): Avoid a race condition
3918 with SIGIO delivery (Bug#11536).
3920 2012-11-03 Chong Yidong <cyd@gnu.org>
3922 * buffer.c (cursor_type): Untabify docstring.
3924 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3926 * frame.h (struct frame): Drop can_have_scroll_bars member
3927 which is meaningless for a long time. Adjust comments.
3928 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
3929 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
3931 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3933 * window.c (decode_next_window_args): Update window arg after
3934 calling decode_live_window and so fix crash reported at
3935 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
3936 by Juanma Barranquero <lekktu@gmail.com>.
3937 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
3938 * font.c (Ffont_at): Likewise.
3940 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
3942 * widget.c (resize_cb): New function.
3943 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
3944 (EmacsFrameResize): Check if all is up to date before changing frame
3947 2012-11-02 Eli Zaretskii <eliz@gnu.org>
3949 Implement backtrace output for fatal errors on MS-Windows.
3950 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
3951 (BACKTRACE_LIMIT_MAX): New macro.
3952 (w32_backtrace): New function.
3953 (emacs_abort): Use w32_backtrace when the user chooses not to
3954 attach a debugger. Update the text of the abort dialog.
3956 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3958 Window-related stuff cleanup here and there.
3959 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
3960 Use decode_any_window.
3961 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
3962 * xdisp.c (Fformat_mode_line): Likewise.
3963 * font.c (Ffont_at): Use decode_live_window.
3964 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
3965 * window.c (decode_next_window_args): Likewise.
3966 (decode_any_window): Remove static.
3967 * window.h (decode_any_window): Add prototype.
3968 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
3969 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
3972 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3974 Remove pad from struct input_event.
3975 * termhooks.h (struct input_event): Remove padding field.
3977 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3978 member is never cons for a long time. Adjust comment.
3979 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3980 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3981 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3982 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3984 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3986 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3988 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3990 Fix crash when using Emacs as commit editor for git (Bug#12697).
3991 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3992 and it is configured in conf_post.h.
3993 (Fcall_process): Don't invoke both setsid and setpgid; the former
3994 is enough, if it exists.
3995 * callproc.c (Fcall_process, child_setup):
3996 * process.c (create_process): Use setpgid.
3997 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3999 * dispnew.c (init_display): Initialize the foreground group
4000 if we are running a tty display.
4001 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4002 * lisp.h (init_foreground_group): New decl.
4003 * sysdep.c (inherited_pgroup): New static var.
4004 (init_foreground_group, tcsetpgrp_without_stopping)
4005 (narrow_foreground_group, widen_foreground_group): New functions.
4006 (init_sys_modes): Narrow foreground group.
4007 (reset_sys_modes): Widen foreground group.
4009 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4011 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4013 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4015 * minibuf.c (read_minibuf): Restore current buffer since
4016 choose_minibuf_frame calling Fset_frame_selected_window may
4017 change it (Bug#12766).
4019 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4021 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4023 2012-10-30 Kenichi Handa <handa@gnu.org>
4025 * font.c (Ffont_at): If WINDOW is specified and it is not
4026 displaying the current buffer, signal an error.
4028 2012-10-29 Daniel Colascione <dancol@dancol.org>
4030 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4031 In preparation for fixing bug#12739, move these functions from
4034 * coding.h, coding.c: ... to here, and compile them only when
4035 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4036 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4038 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4040 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4041 (timer_loop, getitimer, setitimer): Use it instead of
4042 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4044 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4047 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4049 * nsterm.m (NO_APPDEFINED_DATA): New define.
4050 (last_appdefined_event_data): New variable
4051 (last_appdefined_event): Remove.
4052 (ns_select): Initialize t from last_appdefined_event_data instead
4053 of [last_appdefined_event data1].
4054 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4055 remove last_appdefined_event (Bug#12698).
4057 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4059 * frame.c (x_set_font): Catch internal error.
4061 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4063 Avoid overflow in w32 implementation of interval timers.
4064 When possible, for ITIMER_PROF count only times the main thread
4066 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4067 'volatile ULONGLONG' types. All the other data which was
4068 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4069 (GetThreadTimes_Proc): New typedef.
4070 (w32_get_timer_time): New function, returns a suitable time value
4072 (timer_loop): Enter critical section when accessing ULONGLONG
4073 values of the itimer_data struct, as these accesses are no longer
4074 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4075 Remove unused variable.
4076 (init_timers): Initialize s_pfn_Get_Thread_Times.
4077 (start_timer_thread): Don't assign itimer->caller_thread here.
4078 (getitimer): Assign itimer->caller_thread here.
4079 (setitimer): Always call getitimer to get the value of ticks_now.
4080 (sys_spawnve): Avoid compiler warning about format mismatch.
4082 2012-10-26 Eli Zaretskii <eliz@gnu.org>
4084 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4085 mouse movement events if the menu bar is active. This avoids
4086 producing a busy "hour-glass" cursor by Windows if the mouse
4087 pointer is positioned over a tooltip shown for some menu item.
4089 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4091 Don't assume process IDs fit in int.
4092 * emacs.c (shut_down_emacs) [!DOS_NT]:
4093 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4094 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4095 Use pid_t, not int, to store process IDs, as 'int'
4096 is not wide enough on a few platforms (e.g., AIX and IRIX).
4098 2012-10-23 Kenichi Handa <handa@gnu.org>
4100 The following change is to make face-font-rescale-alist work
4101 correctly for non-ASCII fonts.
4103 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4104 (font_open_for_lface): Handle Vface_font_rescale_alist.
4106 2012-10-23 Chong Yidong <cyd@gnu.org>
4108 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4110 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
4112 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
4114 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
4116 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
4119 2012-10-21 Glenn Morris <rgm@gnu.org>
4121 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4123 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4125 Port to OpenBSD 5.1.
4126 * frame.c (Fmouse_position, Fmouse_pixel_position):
4127 * xdisp.c (produce_stretch_glyph):
4128 Declare local vars only when they're needed.
4129 This is clearer and avoids a warning on OpenBSD about unused vars.
4130 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
4131 This is safer, and avoids OpenBSD warnings about unused vars.
4132 * keyboard.c (record_menu_key): Remove unnecessary decl.
4133 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4134 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4135 as our definition clashes with OpenBSD's.
4136 * xfaces.c (load_face_colors, check_lface_attrs)
4137 (get_lface_attributes_no_remap, get_lface_attributes)
4138 (lface_fully_specified_p, x_supports_face_attributes_p)
4139 (tty_supports_face_attributes_p, face_fontset, realize_face)
4140 (realize_x_face, realize_tty_face):
4141 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4142 merely Lisp_Object *. This is more informative and avoids
4143 a warning on OpenBSD about accessing beyond an object's size.

4626 (Fcygwin_convert_path_from_windows): New user functions for
4627 accessing Cygwin path-munging routines.
4629 * cygw32.h: New file.
4630 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4631 UTF-16LE strings temporarily inside non-Lisp-visible string
4634 (w32_strerror): Just what it says on the tin.
4636 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4637 also run for Cygwin; both systems have the same problem with using
4638 GUI facilities in a forked child. Also call syms_of_cygw32,
4639 syms_of_w32select in correct places.
4641 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4642 needs fork-then-exec for daemon launching.
4644 * font.h: Include frame.h.
4646 * image.c: Use the image library cache machinery only when we're
4647 compiling for native WINDOWSNT; Cygwin can use shared libraries
4648 like any other Unixlike system.
4650 * keyboard.c: Clarify a comment regarding the input loop.
4652 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4653 functions directly instead of trying to detect at runtime that our
4654 host operating system supports them. We make this change for two
4655 reasons: Cygwin lacks support for the multibyte character
4656 conversion functions used by the legacy menu code, and Cygwin
4657 never needs to rely on non-Unicode APIs.
4659 * unexw32.c (hinst): Declare extern.
4661 * w32.c: Change header order;
4662 (w32_strerror): Move to w32fns.c because we need it for
4663 non-WINDOWSNT builds.
4665 * w32.h: Add #error macro to make sure we don't include w32.h for
4666 Cygwin builds. Remove w32select declarations.
4668 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4669 w32fns.c. w32console.c is WINDOWSNT-only.
4671 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4672 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4674 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4675 (w32_major_version, w32_minor_version, w32_build_number)
4676 (os_subtype, sound_type): Define here
4677 (w32_defined_color): Make color parameter const for consistency
4678 with other _defined_color functions.
4679 (w32_createwindow): Unconditionally call w32_init_class instead of
4680 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4681 through the code is complex and unnecessary because class
4682 registration is practically free.
4683 (w32_name_of_message): New EMACSDEBUG-only function.
4684 (Fset_message_beep): Move here
4685 (Fx_open_connection): Require that the display name for Windows be
4686 "w32" for consistency, emacsclient disambiguation, and maybe, one
4687 day, multi-window-system support.
4688 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4689 Cygwin files for W32 GUI facilities, since these clearly don't
4690 expect Cygwin names.
4691 (_DebPrint): Define.
4692 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4693 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4694 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4695 (w32_last_error): Remove.
4697 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4699 * w32heap.c (syspage_mask): Declare here.
4700 (cache_system_info): Remove.
4702 * w32inevt.c (faked_key): Define globally, not statically.
4703 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4704 (w32_console_toggle_lock_key): Move to w32fns.c.
4706 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4708 * w32proc.c (_DebPrint): Move to w32fns.c.
4709 * w32select.c: Include string.h, stdio.h for Cygwin.
4710 * w32select.h: New File.
4712 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4714 (w32_message_fd): New variable. Under Cygwin, holds the file
4715 descriptor the system used to tell us about pending thread
4718 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4719 that prevented compilation under non-WINDOWSNT systems.
4721 (w32_initialize): Open /dev/windows and assign it to
4722 w32_message_fd. Provide w32 feature.
4724 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4725 (WM_EMACS_INPUT_READY): add.
4726 (prepend_msg, w32_message_fd): Declare globally.
4729 (keyboard_handle): Use only when WINDOWSNT.
4730 (notify_msg_ready): New function. Posts a message to the main
4731 thread's message queue under CYGWIN, which wakes up the main
4732 thread from select(2) by making the /dev/windows file descriptor
4733 ready. Under WINDOWSNT, it sets an event the same way the old
4736 (post, prepend_msg): Actually call notify_msg_ready instead of
4737 setting the input event directly.
4739 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4741 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4742 but it still has blocs in it, don't return it to the system,
4743 instead of aborting. (Bug#12402)
4745 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4747 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4749 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4750 MAC_OS_X_VERSION_10_6.
4751 (syms_of_nsterm): Remove comment about Panther and above for
4753 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4754 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4755 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4757 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4758 MAC_OS_X_VERSION_10_4.
4760 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4761 MAC_OS_X_VERSION_10_2.
4763 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4765 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4766 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4768 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4769 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4770 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4771 Remove ns_in_resize check.
4772 (ns_clear_frame_area): Remove resize handle code.
4774 * nsfns.m (ns_in_resize): Remove.
4775 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4776 Remove ns_in_resize check.
4778 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4780 Improve sys_siglist detection.
4781 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4782 defined as a macro, as is done in Solaris.
4783 (sys_siglist_entries): New macro.
4784 (save_strsignal): Use it.
4785 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4786 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4788 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4790 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4791 fullscreen/Fullscreen.
4793 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4794 tobar_height is new.
4796 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4797 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4798 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4799 (windowDidResize:): Check for correct window if old style fullscreen.
4800 Capitalize word in comment. Remove incorrect comment.
4801 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4802 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4803 error in drawing background.
4804 (toggleFullScreen:): Remove comment. Rearrange calls.
4805 Set toolbar values to zero, save old height in tobar_height.
4806 Restore tool bar height when leaving fullscreen.
4807 (canBecomeMainWindow): New function.
4809 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4811 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4813 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4815 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4817 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4818 that time stamps of directories could also be changed.
4819 Don't request the too broad GENERIC_WRITE, only the more restrictive
4820 FILE_WRITE_ATTRIBUTES access rights.
4822 * fileio.c (Fset_file_times): Special-case ignoring errors for
4823 directories only on MSDOS, not on MS-Windows.
4825 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4827 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4829 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4831 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4832 see whether CreateFile failed.
4834 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4836 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4837 to avoid similar races.
4838 * keyboard.c (pending_signals): Now bool, not int.
4840 Port timers to OpenBSD, plus check for timer failures.
4841 OpenBSD problem reported by Han Boetes.
4842 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4844 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4845 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4846 like OpenBSD, which has timer_settime but does not declare it.
4847 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4848 whether to use itimerspec-related primitives. All uses of
4849 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4851 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4853 * profiler.c (handle_profiler_signal): Fix a malloc race
4854 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4856 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4858 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4860 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4862 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4863 consistent with the change in return value of 'safe_strsignal'.
4865 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4867 Prefer plain 'static' to 'static inline' (Bug#12541).
4868 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4869 (bidi_set_sor_type, bidi_push_embedding_level)
4870 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
4871 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

4875 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4876 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
4877 Now 'static', not 'static inline'.
4879 Count overruns when profiling; change units to ns.
4880 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4881 Give extra weight to samples after overruns, to attempt to count
4882 the time more accurately.
4883 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4884 the underlying primitives nominally do ns.
4885 (Fprofiler_cpu_start): Document the change. Mention that
4886 the sampling intervals are only approximate.
4888 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4890 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
4892 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
4893 case for the special 0 coding-system.
4895 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
4896 (Fmake_overlay): Remove redundant tests.
4897 (fix_start_end_in_overlays): Remove redundant recentering.
4899 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
4901 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
4902 Update dependencies.
4904 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4906 Fix a malloc race condition involving strsignal.
4907 A signal can arrive in the middle of a malloc, and Emacs's signal
4908 handler can invoke strsignal, which can invoke malloc, which is
4909 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4910 Fix it by altering the signal handler so that it does not invoke
4912 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4913 * process.c (status_message): Use const pointer, in case strsignal
4914 is #defined to safe_strsignal.
4915 * sysdep.c (sys_siglist, init_signals): Always define and
4916 initialize a substitute sys_siglist if the system does not define
4917 one, even if HAVE_STRSIGNAL.
4918 (safe_strsignal): Rename from strsignal. Always define,
4919 using sys_siglist. Return a const pointer.
4920 * syssignal.h (safe_strsignal): New decl.
4921 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4923 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4925 * w32proc.c (timer_loop): Fix code that waits for timer
4926 expiration, to avoid high CPU usage.
4928 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4930 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4931 (sweep_weak_table): Remove redundant prototypes.
4933 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4935 * emacs.c: Move the inclusion of TERM_HEADER after including
4936 windows.h on WINDOWSNT. This avoids compilation problems with
4939 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4941 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4942 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4943 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4944 as the previous version used 'void *'.
4946 * ralloc.c (ROUNDUP): Fix last change.
4947 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4950 * w32proc.c <disable_itimers>: New static flag.
4951 (init_timers): Initialize it to zero, after creating the critical
4952 sections used by the timer threads.
4953 (term_timers): Set to 1 before deleting the critical sections.
4954 (getitimer, setitimer): If disable_itimers is non-zero, return an
4955 error indication without doing anything. Reported by Fabrice
4956 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4957 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4959 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4962 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4963 term_ntproc after all the other bookkeeping, to get timers working
4964 as long as possible.
4966 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4968 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4969 Suggested by Juri Linkov in
4970 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4972 Prefer plain 'static' to 'static inline' (Bug#12541).
4973 With static functions, modern compilers inline pretty well by
4974 themselves; advice from programmers often hurts as much as it helps.
4975 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4976 this change shrinks the text size of the Emacs executable by 1.1%
4977 without affecting CPU significantly in my benchmark.
4978 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

5053 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
5054 Now 'static', not 'static inline'.
5057 (bidi_copy_it): Do the whole copy with a single memcpy.
5058 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
5060 Revert the FOLLOW-SYMLINKS change for file-attributes.
5061 Doing it right would require several changes to Tramp, and there's
5062 not enough time to get that tested before the freeze today.
5063 * dired.c (directory_files_internal, Ffile_attributes):

5271 (handle_profiler_signal): Rename from sigprof_handler_1,
5272 for consistency with other handlers. Do not check whether
5273 cpu_log is a hash-table if garbage collecting, since it

5276 for consistency with other handlers.
5277 (setup_cpu_timer): New function, with much of what used to be in

5279 Prefer timer_settime if available, and prefer
5280 thread cputime clocks, then process cputime clocks, then
5281 monotonic clocks, to the old realtime clock. Use make_timeval
5282 to round more-correctly when falling back to setitimer.
5283 (Fprofiler_cpu_start): Use it.
5284 (Fprofiler_cpu_stop): Prefer timer_settime if available.

5528 Use bool for boolean.
5529 * gtkutil.c (xg_update_frame_menubar):
5530 * xmenu.c (update_frame_menubar):
5531 Return void, not int, since caller ignores return value.

5535 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5537 * makefile.w32-in (BLOCKINPUT_H): Remove.

5554 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5556 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5557 fatal_error_backtrace.
5559 * w32proc.c (sys_kill): Undo last change: don't do anything when
5560 invoked to deliver SIGABRT to our own process. This is now
5561 handled by emacs_raise.
5563 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5565 * w32term.c (w32_read_socket): Remove leftover reference to
5566 interrupt_input_pending.
5568 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5570 Do not use SA_NODEFER.
5571 Problem reported by Dani Moncayo in
5572 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5574 * sysdep.c (emacs_abort): Do not reset signal handler.
5575 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5576 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5577 wanted even on POSIXish hosts, and it doesn't work on Windows.
5579 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5581 * xterm.c (x_term_init): Call fixup_locale before and after calling
5582 gtk_init (Bug#12392).
5584 2012-09-23 Chong Yidong <cyd@gnu.org>
5586 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5587 Vdynamic_library_alist.
5589 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5590 (Fgnutls_available_p): Caller changed.
5592 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5593 (Flibxml_parse_xml_region): Likewise.
5595 * dispextern.h (struct image_type): Remove arg from init function.
5597 * image.c (Finit_image_library, lookup_image_type)
5598 (define_image_type): Remove now-unneeded second arg.
5599 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5600 (init_tiff_functions, init_gif_functions, init_svg_functions):
5601 Arglist and w32_delayed_load calling convention changed.
5602 (gs_type): Remove init_gs_functions; there is no such function.
5603 (valid_image_p, make_image): Fix caller to lookup_image_type.
5605 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5607 Simplify and avoid signal-handling races (Bug#12471).
5609 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5610 Avoid recursive loop if there's a fatal error in the function itself.
5611 * atimer.c (pending_atimers):
5612 * blockinput.h: Don't include "atimer.h"; no longer needed.
5613 (interrupt_input_pending): Remove. All uses removed.
5614 pending_signals now counts both atimers and ordinary interrupts.
5615 This is less racy than having three separate pending-signal flags.
5616 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5618 Rename from their upper-case counterparts BLOCK_INPUT,
5619 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5620 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5621 This makes it easier to access volatile variables more accurately.
5622 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5623 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5624 that's more reliable if the code is buggy and sets
5625 interrupt_input_blocked to a negative value. All uses changed.
5626 * atimer.c (deliver_alarm_signal):
5627 Remove. No need to deliver this to the parent; any thread can
5628 handle this signal now. All uses replaced by underlying handler.
5629 * atimer.c (turn_on_atimers):
5630 * dispnew.c (handle_window_change_signal):
5631 * emacs.c (handle_danger_signal):
5632 * keyboard.c (kbd_buffer_get_event):
5633 Don't reestablish signal handler; not needed with sigaction.
5634 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5636 Rework to avoid unnecessary accesses to volatile variables.
5637 (UNBLOCK_INPUT_TO): Now a function.
5638 (totally_unblock_input, unblock_input): New decls.
5639 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5640 (init_data): Remove. Necessary stuff now done in init_signal.
5641 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5642 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5643 (fatal_error_code): Remove; no longer needed.
5644 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5645 it doesn't always backtrace. All uses changed. No need to reset
5646 signal to default, since sigaction and/or die does that for us now.
5647 Use emacs_raise (FOO), not kill (getpid (), FOO).
5648 (main): Check more-accurately whether we're dumping.
5649 Move fatal-error setup to sysdep.c
5650 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5651 * gtkutil.c (xg_get_file_name, xg_get_font):
5652 Remove no-longer-needed signal-mask manipulation.
5653 * keyboard.c, process.c (POLL_FOR_INPUT):
5654 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5655 * keyboard.c (read_avail_input): Remove.
5656 All uses replaced by gobble_input.
5657 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5658 (kbd_buffer_store_event_hold, gobble_input):
5659 (record_asynch_buffer_change) [USABLE_SIGIO]:
5660 (store_user_signal_events):
5661 No need to mess with signal mask.
5662 (gobble_input): If blocking input and there are terminals, simply
5663 set pending_signals to 1 and return. All hooks changed to not
5664 worry about whether input is blocked.
5665 (process_pending_signals): Clear pending_signals before processing
5666 them, in case a signal comes in while we're processing.
5667 By convention callers now test pending_signals before calling us.
5668 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5669 New functions, to support changes to blockinput.h.
5670 (handle_input_available_signal): Now extern.
5671 (reinvoke_input_signal): Remove. All uses replaced by
5673 (quit_count): Now volatile, since a signal handler uses it.
5674 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5675 All callers changed. Block SIGINT only if not already blocked.
5676 Clear sigmask reliably, even if Fsignal returns, which it can.
5677 Omit unnecessary accesses to volatile var.
5678 (quit_throw_to_read_char): No need to restore sigmask.
5679 * keyboard.c (gobble_input, handle_user_signal):
5680 * process.c (wait_reading_process_output):
5681 Call signal-handling code rather than killing ourselves.
5682 * lisp.h: Include <float.h>, for...
5683 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5684 (pending_signals): Now volatile.
5685 (syms_of_data): Now const if IEEE floating point.
5686 (handle_input_available_signal) [USABLE_SIGIO]:
5687 (terminate_due_to_signal, record_child_status_change): New decls.
5688 * process.c (create_process): Avoid disaster if memory is exhausted
5689 while we're processing a vfork, by tightening the critical section
5691 (send_process_frame, process_sent_to, handle_pipe_signal)
5692 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5694 (send_process): No need for setjmp/longjmp any more, since the
5695 SIGPIPE stuff is now gone. Instead, report an error if errno
5697 (record_child_status_change): Now extern. PID and W are now args.
5698 Return void, not bool. All callers changed.
5699 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5700 Remove. All uses removed. This bug should be fixed now in a
5702 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5703 and record the child status change directly. This avoids the
5704 need to futz with the signal mask.
5705 (process_fatal_action): Move here from emacs.c.
5706 (emacs_sigaction_flags): New function, containing
5707 much of what used to be in emacs_sigaction_init.
5708 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5709 caught by emacs, to make races less likely.
5710 (deliver_process_signal): Rename from handle_on_main_thread.
5712 (BACKTRACE_LIMIT_MAX): Now at top level.
5713 (thread_backtrace_buffer, threadback_backtrace_pointers):
5715 (deliver_thread_signal, deliver_fatal_thread_signal):
5716 New functions, for more-accurate delivery of thread-specific signals.
5717 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5718 (deliver_arith_signal): Handle in this thread, not
5719 in the main thread, since it's triggered by this thread.
5720 (maybe_fatal_sig): New function.
5721 (init_signals): New arg DUMPING so that we can be more accurate
5722 about whether we're dumping. Caller changed.
5723 Treat thread-specific signals differently from process-general signals.
5724 Block all signals while handling fatal error; that's safer.
5725 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5727 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5728 Ignore SIGPIPE unless batch.
5729 (emacs_backtrace): Output backtrace for the appropriate thread,
5730 which is not necessarily the main thread.
5731 * syssignal.h: Include <stdbool.h>.
5732 (emacs_raise): New macro.
5733 * xterm.c (x_connection_signal): Remove; no longer needed
5734 now that we use sigaction.
5735 (x_connection_closed): No need to mess with sigmask now.
5736 (x_initialize): No need to reset SIGPIPE handler here, since
5737 init_signals does this for us now.
5739 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5741 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5742 background rect may be larger (Bug#12245).
5744 2012-09-23 Chong Yidong <cyd@gnu.org>
5746 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5748 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5750 * .gdbinit: Just stop at fatal_error_backtrace.
5751 See Stefan Monnier's request in
5752 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5753 Remove no-longer-used query of system type.
5755 2012-09-22 Chong Yidong <cyd@gnu.org>
5757 * search.c (Freplace_match): Doc fix (Bug#12325).
5759 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5761 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5762 (Fline_end_position): Doc fix.
5764 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5766 2012-09-22 Chong Yidong <cyd@gnu.org>
5768 * dispextern.h (struct image_type): Add new slot, storing a type
5769 initialization function.
5771 * image.c (define_image_type): Call the image initializer function
5772 if it is defined. Arguments and return value changed.
5773 (valid_image_p, make_image): Callers changed.
5774 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5775 (gif_type, imagemagick_type, svg_type, gs_type):
5776 Add initialization functions.
5777 (Finit_image_library): Call lookup_image_type.
5778 (CHECK_LIB_AVAILABLE): Macro deleted.
5779 (lookup_image_type): Call define_image_type here, rather than via
5780 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5781 (syms_of_image): Move define_image_type calls for xbm_type and
5782 pbm_type to lookup_image_type.
5784 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5786 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5787 'idle_timers' from here ...
5788 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5789 lists, to avoid infloops when the timer does something stupid,
5790 like reinvoke itself with the same or smaller time-out.
5793 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5795 * window.c (Fsplit_window_internal): Handle only Qt value of
5796 Vwindow_combination_limit separately.
5797 (Qtemp_buffer_resize): New symbol.
5798 (Vwindow_combination_limit): New default value.
5801 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5803 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5804 the new overlay string. (Bug#10159)
5806 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5808 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5809 or that fprintf is async-signal-safe. POSIX doesn't require
5812 2012-09-22 Chong Yidong <cyd@gnu.org>
5814 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5817 2012-09-22 Kenichi Handa <handa@gnu.org>
5819 * composite.c (composition_reseat_it): Handle the case that a
5820 grapheme cluster is not covered by a single font (Bug#12352).
5822 2012-09-21 Chong Yidong <cyd@gnu.org>
5824 * image.c (define_image_type): Avoid adding duplicate types to
5825 image_types (Bug#12463). Suggested by Jörg Walter.
5827 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5829 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5830 (print_load_command_name): Add case LC_DATA_IN_CODE.
5831 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5833 2012-09-21 Glenn Morris <rgm@gnu.org>
5835 * eval.c (Frun_hook_with_args_until_success)
5836 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5838 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5840 * fileio.c (Ffile_selinux_context): Only call freecon when
5841 lgetfilecon succeeded.
5842 (Fset_file_selinux_context): Likewise. (Bug#12444)
5844 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5846 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5847 reordering, locate the cursor by calling set_cursor_from_row; if
5848 that fails, clear the desired glyph matrix before returning a
5849 failure indication to the caller. Fixes leaving garbled display
5850 when fast scrolling with a down-key. (Bug#12403)
5851 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5852 scrolling through multibyte text.
5854 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5856 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5857 calling mark_vectorlike since that's the one that marks the window.
5858 (mark_discard_killed_buffers): Mark the final cdr.
5859 * window.h (struct window): Move prev/next_buffers to the
5860 non-standard fields.
5861 * window.c (make_window): Initialize prev/next_buffers manually.
5863 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5865 Omit unused arg EXPECTED from socket hooks.
5866 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5867 * nsterm.m (ns_term_init):
5868 * termhooks.h (struct terminal.read_socket_hook):
5869 * w32inevt.c (w32_console_read_socket):
5870 * w32term.c (w32_read_socket):
5871 * xterm.c (XTread_socket):
5872 Omit unused arg EXPECTED. All callers changed.
5873 (store_user_signal_events): Return void, not int, since callers no
5874 longer care about the return value. All uses changed.
5876 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5878 * w32gui.h (XParseGeometry): Do not declare.
5880 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5882 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5883 Ignore 'expected'. See Eli Zaretskii in
5884 <http://bugs.gnu.org/12471#8> (last line).
5886 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5887 (XParseGeometry): Now static. Substitute extremal values for
5888 values that are out of range.
5890 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5892 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5894 * nsfns.m (XParseGeometry): Remove.
5895 (Fx_create_frame): Call x_set_offset to correctly interpret
5896 top_pos in geometry.
5898 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5899 (Fx_parse_geometry): If there is a space in string, call
5900 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5902 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5904 * search.c (scan_buffer): Use character positions in calls to
5905 region_cache_forward and region_cache_backward, not byte
5906 positions. (Bug#12196)
5908 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5909 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5911 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5912 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5913 emacs_blocked_malloc, now deleted.
5915 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5917 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5918 The workaround was for improving performance on Solaris 2.4, but
5919 is getting in the way now. Emacs will still work if someone is
5920 still running Solaris 2.4 in a museum somewhere; Sun dropped
5921 support for Solaris 2.4 in 2003.
5922 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5923 * process.c (create_process) [HAVE_WORKING_VFORK]:
5924 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5925 since Emacs no longer uses vfork on that platform.
5927 2012-09-17 Glenn Morris <rgm@gnu.org>
5929 * emacs.c: Use COPYRIGHT.
5931 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5933 Remove configure's --without-sync-input option (Bug#12450).
5934 When auditing signal-handling in preparation for cleaning it up,
5935 I found that SYNC_INPUT has race conditions and would be a real
5936 pain to fix. Since it's an undocumented and deprecated
5937 configure-time option, now seems like a good time to remove it.
5938 Also see <http://bugs.gnu.org/11080#16>.
5939 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5940 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5941 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5942 (malloc_hysteresis):
5943 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5944 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5945 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5946 (dont_register_blocks, bytes_used_when_reconsidered)
5947 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5948 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5949 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5950 Remove. All uses removed.
5951 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5952 implementation, one that depends on whether the new macro
5953 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5955 * atimer.c (run_timers, handle_alarm_signal):

5964 * xterm.c (XTread_socket):
5966 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5967 * eval.c (handling_signal): Remove. All uses removed.
5968 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5969 All uses replaced with the SYNC_INPUT version.
5970 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5972 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5975 * font.c (Ffont_shape_gstring): Remove unused local.
5977 2012-09-16 Glenn Morris <rgm@gnu.org>
5979 * Makefile.in (clean): No longer run nextstep's clean.
5981 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5983 (ns-app): Move here from ns.mk, and simplify.
5984 (clean): Simplify nextstep entry.
5985 * ns.mk: Remove file.
5987 2012-09-17 Kenichi Handa <handa@gnu.org>
5989 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5990 not covert the last few charactes.
5992 2012-09-16 Kenichi Handa <handa@gnu.org>
5994 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5995 here, but just check the validity of glyphs in the glyph-string.
5997 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5999 * window.c (Fwindow_parameter, Fset_window_parameter):
6000 Accept any window as argument (Bug#12452).
6002 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6004 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6005 to ns_term_init to avoid memory leak.
6007 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6008 explicit retain/release.
6009 (ns_term_init): Only allow one display. Initialize outerpool and
6012 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6014 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6015 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6016 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6017 the Microsoft problem in a different way, by altering ../nt/config.nt.
6019 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6034 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6035 by lisp.h. This completes removal of setjmp.h inclusion
6036 erroneously announced in the previous commit. (Bug#12446)
6038 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6041 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6042 not defined as a macro. The latter happens on MS-Windows.
6045 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6047 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6048 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6049 Some instances of '#include <setjmp.h>' removed, if the
6050 only reason for the instance was because "lisp.h" was included.
6051 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6052 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6053 and _longjmp with the new symbols. Emacs already uses _setjmp if
6054 available, so this change affects only POSIXish hosts that have
6055 sigsetjmp but not _setjmp, such as some versions of Solaris and
6056 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6057 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6058 (png_load_body) [HAVE_PNG]:
6059 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6060 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6061 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6062 since PNG requires jmp_buf. This is the only exception to the
6063 general rule that we now use sys_setjmp and sys_longjmp.
6064 This exception is OK since this code does not change the signal
6065 mask or longjmp out of a signal handler.
6067 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6069 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6070 Include "syssignal.h", for 'main_thread'.
6072 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6074 Avoid out-of-range marker position (Bug#12426).
6075 * insdel.c (replace_range, replace_range_2):
6076 Adjust markers before overlays, as suggested by comments.
6077 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6078 Remove redundant check before calling offset_intervals.
6080 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6082 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6083 current buffer (Bug#12387).
6085 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6087 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6089 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6091 Use a more backwards-compatible timer format (Bug#12430).
6092 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6093 vector element, not from the 4th, since PSECS is now at the end.
6094 (Fcurrent_idle_time): Doc fix.
6096 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6098 Function to mark objects and remove killed buffers at once.
6099 * alloc.c (discard_killed_buffers): Rename to ...
6100 (mark_discard_killed buffers) ... new name. Add marking
6101 of remaining objects. Fix comment. Adjust users.
6102 (mark_object): Do not touch frame buffer lists here.
6103 * frame.c (delete_frame): Reset frame buffer lists here.
6105 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6107 Better workaround for GNOME bug when --enable-gcc-warnings.
6108 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6109 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6110 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6112 Simplify SIGIO usage (Bug#12408).
6113 The code that dealt with SIGIO was crufty and confusing, e.g., it
6114 played tricks like "#undef SIGIO" but these tricks were not used
6115 consistently. Simplify mostly by not #undeffing standard symbols,
6116 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6117 or not as we please) rather than "defined SIGIO" (standard symbol
6118 that we probably shouldn't #undef).
6119 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6120 Modules that need it can include it.
6121 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6122 * dispextern.h (ignore_sigio): New decl.
6123 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6124 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6125 * emacs.c (shut_down_emacs):
6126 * keyboard.c (kbd_buffer_store_event_hold):
6127 Use ignore_sigio rather than invoking 'signal' directly.
6128 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6130 (FIONREAD, SIGIO): Do not #undef.
6131 (tty_read_avail_input): Use #error rather than a syntax error.
6132 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6133 for I_PIPE, used by SETUP_SLAVE_PTY.
6134 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6135 * sysdep.c (croak): Remove; no longer needed. This bit of
6136 temporary code, with Fred N. Fish's comment that it's temporary,
6137 has been in Emacs since at least 1992!
6138 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6139 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6140 * syssignal.h (croak): Remove decl.
6141 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6142 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6143 now that we're termios-only.
6144 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6145 * term.c (dissociate_if_controlling_tty): Use #error rather than
6148 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6149 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6150 to work around GNOME bug 683906.
6151 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6152 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6153 This works around GCC bug 54561.
6155 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6157 More fixes for 'volatile' and setjmp/longjmp.
6158 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6159 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6160 (png_load_body) [HAVE_PNG]:
6161 (jpeg_load_body) [HAVE_JPEG]:
6162 New function, with most of the old parent function's body.
6163 (png_load) [HAVE_PNG]:
6164 (jpeg_load) [HAVE_JPEG]:
6165 Invoke the new function, to avoid longjmp munging our locals.
6166 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6167 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6168 longjmp is passed 2, as the C standard doesn't guarantee this.
6169 Instead, store the failure code into mgr->failure_code.
6171 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6173 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6174 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6175 (syms_of_keyboard): Remove support for unread-command-char.
6177 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6179 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6180 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6181 violation. (Bug#12426)
6183 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6185 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6187 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6189 * eval.c: Add `inhibit-debugger'.
6190 (Qinhibit_debugger): New symbol.
6191 (call_debugger): Bind it instead of Qdebug_on_error.
6192 (maybe_call_debugger): Test Vinhibit_debugger.
6193 (syms_of_eval): Define inhibit-debugger.
6194 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6195 (syms_of_xdisp): Remove inhibit-debug-on-message.
6197 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6199 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6200 If a nonvolatile local variable is written before a _longjmp to
6201 the frame containing the variable, and is read after the _longjmp,
6202 the value read is indeterminate. Some local variables of type
6203 'struct handler' and 'struct catchtag' are used in this way, so
6204 mark each of their slots as volatile if the slot can be set before
6205 _longjmp and read afterwards.
6206 * lisp.h (struct handler): var and chosen_clause are now volatile.
6207 (struct catchtag): val, next, and pdlcount are now volatile.
6209 * bidi.c (bidi_push_it, bidi_pop_it):
6210 * fns.c (copy_hash_table):
6211 * image.c (define_image_type):
6212 * keyboard.c (kbd_buffer_store_event_hold):
6213 * process.c (Fprocess_send_eof):
6214 * xfaces.c (x_create_gc) [HAVE_NS]:
6215 * xgselect.c (xg_select):
6216 Prefer assignment to memcpy when either will do.
6218 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6219 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6220 time an item is removed. No need to mark this function 'inline';
6221 the compiler knows better than we do.
6223 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6225 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6226 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6227 to change_frame_size (Bug#12388).
6228 (windowDidResize:): Pass YES to updateFrameSize.
6230 * nsterm.h: Add delay parameter to updateFrameSize.
6232 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6234 Discard killed buffers from deleted window and frame objects.
6235 This reduces an amount of references to killed buffers and
6236 helps GC to reclaim them faster.
6237 * alloc.c (discard_killed_buffers): New function.
6238 (mark_object): Use it for deleted windows and frames.
6239 (mark_object): If symbol's value is set up for a killed buffer
6240 or deleted frame, restore its global binding.
6241 * data.c (swap_in_global_binding): Add GC notice.
6242 (swap_in_symval_forwarding): Use convenient set_blv_where.
6243 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6244 * window.h: ... to here.
6246 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6248 Convenient macro to check whether the buffer is live.
6249 * buffer.h (BUFFER_LIVE_P): New macro.
6250 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6251 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6253 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6255 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6256 composition cases (Bug#12364).
6258 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6259 overhang of succeeding glyphs overlapping box cursor.
6261 * w32term.c (x_draw_glyph_string): Likewise.
6263 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6265 Simplify, document, and port floating-point (Bug#12381).
6266 The porting part of this patch fixes bugs on non-IEEE platforms
6267 with frexp, ldexp, logb.
6268 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6270 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6271 support, by removing commented-out code and briefly listing the
6272 C89 functions excluded. The commented-out stuff was confusing
6273 maintenance, e.g., we thought we needed cbrt but it was commented out.
6274 (logb): Remove decl; no longer needed.
6275 (isfinite): New macro, if not already supplied.
6276 (isnan): Don't replace any existing macro.
6277 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6278 are present on all C89 platforms.
6279 (Ffrexp): Do not special-case zero, as frexp does the right thing
6281 (Flogb): Do not use logb, as it doesn't have the desired meaning
6282 on hosts that use non-base-2 floating point. Instead, stick with
6283 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6284 frexp, to avoid getting an unspecified result.
6286 * xdisp.c (Qinhibit_debug_on_message): Now static.
6288 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6290 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6291 NSBezierPath (Bug#12131).
6293 2012-09-10 Chong Yidong <cyd@gnu.org>
6295 * fns.c (Fdelq, Fdelete): Doc fix.
6297 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6299 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6300 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6302 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6304 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6305 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6308 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6310 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6311 left fringe if the window has a left margin. This avoids leaving
6312 traces of the cursor because its leftmost pixel is not drawn over.
6314 * dispnew.c (update_window_line): When the left margin area of a
6315 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6316 that screen line. (Bug#12277)
6318 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6320 Assume C89 or later for math functions (Bug#12381).
6321 This simplifies the code, and makes it a bit smaller and faster,
6322 and (most important) makes it easier to clean up signal handling
6323 since we can stop worring about floating-point exceptions in
6324 library code. That was a problem before C89, but the problem
6325 went away many years ago on all practical Emacs targets.
6326 * data.c, image.c, lread.c, print.c:
6327 Don't include <math.h>; no longer needed.
6328 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6329 might be autoconfigured, as that never happens.
6331 * doprnt.c (DBL_MAX_10_EXP):
6332 * print.c (DBL_DIG):
6333 Remove. C89 or later always defines these.
6334 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6335 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6336 (arith_error, domain_error, domain_error2):
6337 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6338 no longer needed -- we simply return what C returns. All uses removed.
6339 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6341 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6342 Remove. All uses expanded, as these macros are no longer used
6343 more than once and are now more trouble than they're worth.
6344 (Ftan): Use tan, not sin / cos.
6345 (Flogb): Assume C89 frexp.
6346 (fmod_float): Assume C89 fmod.
6347 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6348 (init_floatfns): Remove. All uses removed.
6350 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6352 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6353 compositeToPoint for OSX < 10.6 (Bug#12390).
6355 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6357 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6358 This produces more-accurate results.
6360 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6362 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6363 changes (Bug#12088).
6365 2012-09-08 Chong Yidong <cyd@gnu.org>
6367 * syntax.c (Fstring_to_syntax): Doc fix.
6369 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6371 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6372 in the internal border.
6373 (x_set_window_size): Remove static variables and their usage.
6374 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6375 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6376 Remove fringe/internal border adjustment (Bug#11052).
6377 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6378 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6379 (ns_fix_rect_ibw): Remove.
6380 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6381 (ns_dumpglyphs_box_or_relief): Ditto.
6382 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6384 (ns_dumpglyphs_image): Ditto.
6385 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6387 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6388 their usage. Add fringe_extended_p and its use as in other terms.
6389 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6390 scroll bar was removed.
6391 (updateFrameSize): New function.
6392 (windowDidResize): Move code to updateFrameSize and call it.
6394 * nsterm.h (EmacsView): Add updateFrameSize.
6396 2012-09-07 Chong Yidong <cyd@gnu.org>
6398 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6400 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6402 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6404 More signal-handler cleanup (Bug#12327).
6405 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6406 Problem introduced when merging patches. Noted by Eli Zaretskii in
6407 <http://bugs.gnu.org/12327#67>.
6408 * floatfns.c: Comment fix.
6409 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6410 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6411 and anyway the declaration is harmless even if SIGDANGER is not defined.
6412 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6413 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6414 source files not surprisingly expected syssignal.h to define, or
6415 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6416 Include <sys/ioctl.h>, for FIONREAD.
6417 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6418 This eliminates a problem whereby other files mysteriously had
6419 to include "syssignal.h" before including "systty.h" if they
6420 wanted to use "#ifdef SIGIO".
6422 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6424 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6426 * w32.c (sigemptyset): Empty the set.
6427 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6429 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6431 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6433 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6434 (mark_object): Likewise for frame objects.
6436 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6438 * syssignal.h (handle_on_main_thread): Always declare,
6439 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6440 This ports to platforms without HAVE_PTHREAD.
6442 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6444 Signal-handler cleanup (Bug#12327).
6445 Emacs's signal handlers were written in the old 4.2BSD style with
6446 sigblock and sigmask and so forth, and this led to some
6447 inefficiencies and confusion. Rewrite these to use
6448 pthread_sigmask etc. without copying signal sets around. Also,
6449 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6450 'signal', and instead use functions that do not attempt to take
6451 over the system name space. This patch causes Emacs's text
6452 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6453 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6454 Do not include <signal.h> or "syssignal.h", as these
6455 modules do not use signals.
6456 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6457 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6458 Do not include <signal.h>, as "syssignal.h" does that for us now.
6459 * atimer.c (sigmask_atimers): New function.
6460 (block_atimers, unblock_atimers): New functions,
6461 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6463 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6464 no longer needed here.
6465 * emacs.c (main): Inspect existing signal handler with sigaction,
6466 so that there's no need to block and unblock SIGHUP.
6467 * sysdep.c (struct save_signal): New member 'action', replacing
6468 old member 'handler'.
6469 (save_signal_handlers, restore_signal_handlers):
6470 Use sigaction instead of 'signal' to save and restore.
6471 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6472 New function. All users of 'signal' modified to use set_sighandler
6473 if they're writeonly, and to use sys_signal if they're read+write.
6474 (emacs_sigaction_init, forwarded_signal): New functions.
6475 (sys_signal): Remove. All uses replaced by calls to sigaction
6476 and emacs_sigaction_init, or by direct calls to 'signal'.
6477 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6478 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6479 all uses replaced by pthread_sigmask etc. calls.
6480 * syssignal.h: Include <signal.h>.
6481 (emacs_sigaction_init, forwarded_signal): New decls.
6482 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6483 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6484 (sigmask, sys_sigmask): Remove; no longer needed.
6485 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6486 (sigblock, sigunblock, sigfree):
6487 (sigsetmask) [!defined sigsetmask]:
6488 Remove. All uses replaced by pthread_sigmask.
6489 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6490 no longer need to be replaced, and its typical old uses
6491 are now done via emacs_sigaction_init and sigaction.
6492 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6493 (sys_sigdel): Remove; unused.
6494 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6496 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6498 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6499 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6501 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6503 Explicitly mark buffer_defaults and buffer_local_symbols.
6504 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6505 mark_local_symbols here.
6506 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6507 since special buffers aren't marked here any more.
6508 (allocate_buffer): Chain new buffer with all_buffers here...
6509 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6511 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6512 (syms_of_buffer): Remove staticpro of the above.
6513 (init_buffer_once): Set names for buffer_defaults and
6514 buffer_local_symbols.
6516 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6518 Use bool for booleans in font-related modules.
6519 * font.c (font_intern_prop, font_style_to_value)
6520 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6521 (generate_otf_features, font_check_otf_features, font_check_otf)
6522 (font_match_p, font_list_entities, font_at):
6523 * fontset.c (fontset_id_valid_p, reorder_font_vector
6524 (fontset_find_font, Fset_fontset_font)
6525 (face_suitable_for_char_p) [0]:
6526 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6527 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6528 (m17n_flt_initialized, ftfont_shape_by_flt):
6529 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6530 * nsfont.m (nsfont_draw):
6531 * w32font.c (w32font_draw):
6532 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6533 Use bool for booleans.
6534 * font.h: Adjust to above API changes.
6535 (struct font, struct font_driver, struct font_driver_list):
6536 Use bool for booleans.
6537 (struct font): Remove useless member encoding_type.
6539 * fontset.c, xftfont.c: Omit unnecessary static decls.
6541 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6543 * alloc.c (mark_object): Revert window marking code
6544 since it's unsafe for the Fset_window_configuration.
6546 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6548 Fix race conditions with signal handlers and errno (Bug#12327).
6549 Be more systematic about preserving errno whenever a signal
6550 handler returns, even if it's not in the main thread. Do this by
6551 renaming signal handlers to distinguish between signal delivery
6552 and signal handling. All uses changed.
6553 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6554 * data.c (deliver_arith_signal): Rename from arith_error.
6555 * dispnew.c (deliver_window_change_signal): Rename from
6556 window_change_signal.
6557 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6558 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6559 * keyboard.c (deliver_input_available_signal): Rename from
6560 input_available_signal.
6561 (deliver_user_signal): Rename from handle_user_signal.
6562 (deliver_interrupt_signal): Rename from interrupt_signal.
6563 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6564 (deliver_child_signal): Rename from sigchld_handler.
6565 * atimer.c (handle_alarm_signal):
6566 * data.c (handle_arith_signal):
6567 * dispnew.c (handle_window_change_signal):
6568 * emacs.c (handle_fatal_signal, handle_danger_signal):
6569 * keyboard.c (handle_input_available_signal):
6570 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6571 * process.c (handle_pipe_signal, handle_child_signal):
6572 New functions, with the actual signal-handling code taken from the
6573 original respective signal handlers, sans the sporadic attempts to
6574 preserve errno, since that's now done by handle_on_main_thread.
6575 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6576 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6577 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6579 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6580 Move initialization of main_thread to sysdep.c's init_signals.
6581 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6582 our usage, and simplifies the mainline code.
6583 (record_child_status_change): New static function, as a helper
6584 for handle_child_signal, and with most of the old child handler's
6586 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6587 (handle_child_signal): Use the above.
6588 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6589 Moved here from emacs.c.
6590 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6591 code moved here from emacs.c's main function.
6592 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6593 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6594 This lets callers save and restore errno properly.
6596 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6598 Remove redundant or unused things here and there.
6599 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6600 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6601 * editfns.c (Fcompare_buffer_substrings): Likewise.
6602 * frame.h (struct terminal, struct font_driver_list):
6603 Remove redundant declarations.
6604 * window.h (Qleft, Qright): Likewise.
6606 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6608 Do not mark objects from deleted buffers, windows and frames.
6609 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6610 (mark_object): Likewise for windows and frames.
6612 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6614 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6615 buffer_defaults and buffer_local_symbols as valid objects.
6616 Return special value to denote them.
6618 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6620 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6621 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6622 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6623 (file_name_absolute_p, Fsubstitute_in_file_name):
6624 (check_executable, check_writable, Ffile_accessible_directory_p)
6625 (Fset_file_selinux_context, Fdefault_file_modes)
6626 (Finsert_file_contents, choose_write_coding_system)
6627 (Fwrite_region, build_annotations, a_write, e_write)
6629 * filelock.c (boot_time_initialized, get_boot_time)
6630 (get_boot_time_1, lock_file_1, within_one_second):
6631 * floatfns.c (in_float):
6632 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6633 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6634 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6635 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6636 * window.c (compare_window_configurations):
6637 Use bool for booleans.
6638 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6639 (Fdefault_file_modes): Now mode_t, not int, for modes.
6640 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6641 (internal_delete_file): Now returns void, not a (boolean) int,
6642 since nobody was looking at the return value.
6643 * lisp.h, window.h: Adjust to above API changes.
6645 * xdisp.c (set_message): Simplify and reindent last change.
6647 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6649 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6651 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6653 * eval.c (call_debugger): Make the function non-static so that we
6654 can call it from set_message.
6656 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6657 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6659 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6661 Give more-useful info on a fatal error (Bug#12328).
6662 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6663 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6664 of doing the work ourselves.
6665 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6666 do most of the work.
6667 (fatal_error_backtrace): New function, taken from the guts
6668 of the old fatal_error_signal, but with a new option to output
6670 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6671 info about the signal than just its number.
6672 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6673 * sysdep.c: Include <execinfo.h>
6674 (emacs_backtrace): New function, taken partly from the previous
6675 code of the 'die' function.
6676 (emacs_abort): Call fatal_error_backtrace rather than abort.
6678 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6680 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6681 eager (load-time) macro-expansion.
6682 * lisp.mk (lisp): Add macroexp.
6684 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6686 Simplify redefinition of 'abort' (Bug#12316).
6687 Do not try to redefine the 'abort' function. Instead, redo
6688 the code so that it calls 'emacs_abort' rather than 'abort'.
6689 This removes the need for the NO_ABORT configure-time macro
6690 and makes it easier to change the abort code to do a backtrace.
6691 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6692 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6693 Remove; sysdep.c's emacs_abort now takes its place.
6694 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6695 'abort' changed to use 'emacs_abort'.
6696 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6697 (abort) [!defined abort]: Rename to ...
6698 (emacs_abort): ... new name.
6699 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6700 the place of the old 'abort' in emacs.c.
6701 * w32.c, w32fns.c (abort): Do not #undef.
6702 * w32.c (emacs_abort): Rename from w32_abort.
6704 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6706 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6707 offsets[j].dv, since the y axis of the screen coordinates points
6708 down, while the y axis of the font definition coordinates points
6709 up. This fixes display of Arabic diacritics such as KASRA and
6710 KASRATAN. (Bug#11860)
6712 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6714 Be more systematic about _setjmp vs setjmp.
6715 * alloc.c (test_setjmp, mark_stack):
6716 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6717 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6718 (png_load, my_error_exit, jpeg_load):
6719 * process.c (send_process_trap, send_process):
6720 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6721 The underscored versions are up to 30x faster on some hosts.
6722 Formerly, the code used setjmp+longjmp sometimes and
6723 _setjmp+_longjmp at other times, with no particular reason to
6724 prefer setjmp+longjmp.
6726 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6728 Fix minor problem found by static checking.
6729 * buffer.c (Fdelete_all_overlays): Return nil.
6731 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6733 * buffer.c (Fdelete_all_overlays): New function.
6735 2012-09-03 Chong Yidong <cyd@gnu.org>
6737 * gtkutil.c: Add extern decl for Qxft.
6739 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6741 * emacs.c, eval.c: Use bool for boolean.
6742 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
6743 (malloc_using_checking) [DOUG_LEA_MALLOC]:
6744 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:

6748 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
6749 (maybe_call_debugger, Fbacktrace):
6750 * process.c (read_process_output, exec_sentinel):
6751 Use bool for booleans.
6752 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
6753 All callers changed.
6754 * eval.c (interactive_p): Omit always-true boolean argument
6755 EXCLUDE_SUBRS_P. All callers changed.
6756 * dispextern.h, lisp.h: Reflect above API changes.
6757 * firstfile.c (dummy): Use the address of 'main', whose signature
6758 won't change, instead of the address of 'initialize', whose
6759 signature just changed from int to bool.
6760 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6761 * msdos.c (fatal_error_in_progress): ... from here.
6762 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6764 (redisplay_internal, unwind_redisplay): Simply clear
6765 REDISPLAYING_P when unwinding, instead of saving its previous,
6766 always-false value and then restoring it.
6768 Clean up some extern decls.
6769 Mostly, this hoists extern decls out of .c files and into .h files.
6770 That way, we're more likely to catch errors if the interfaces change.
6771 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6772 declare xg_mark_data.
6773 * dispextern.h (x_frame_parm_handlers):
6775 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
6776 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
6777 (Qultra_bold, Qoblique, Qitalic):
6778 Move extern decl here from .c file.
6779 * alloc.c (xg_mark_data) [USE_GTK]:
6781 * eval.c (Qlexical_binding):
6782 * fns.c (time) [!HAVE_UNISTD_H]:

6791 * xfont.c (x_clear_errors):
6792 * xterm.c (x_frame_parm_handlers):
6793 Remove now-redundant extern decls.
6794 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6795 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6797 * xfaces.c: Remove unnecessary static decls.
6798 * xterm.c (updating_frame): Remove decl of nonexistent object.
6800 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6801 when building globals.h, as the objects that are not built on
6802 this host are not needed to compile C files on this host.
6804 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6806 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
6808 * frame.h: Add missing prototype for x_wm_set_size_hint.
6810 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

6814 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
6815 (Fsubstitute_command_keys):

6856 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6857 more than one grapheme cluster passed to the shaper: compute the
6858 offset adjustment values separately for each cluster. (Bug#11860)
6860 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6861 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6862 about implicit conversions from integer to pointer.
6864 2012-09-01 Daniel Colascione <dancol@dancol.org>
6866 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

6920 window system declarations.
6922 * frame.h: Move common functions here: set_frame_menubar,
6923 x_set_window_size, x_sync, x_get_focus_frame,
6924 x_set_mouse_position, x_set_mouse_pixel_position,
6925 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6955 the frames which are reachable from Vframe_list.
6956 * term.c (mark_ttys): Remove.
6957 (init_tty): Safely initialize 'top_frame' slot with Qnil.

6981 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6982 for GCC 4.7.1 x86-64.
6984 2012-08-30 Glenn Morris <rgm@gnu.org>
6986 * lread.c (init_lread): For out-of-tree builds, only add the
6987 source directory's site-lisp dir to the load-path if it exists,
6988 consistent with in-tree builds. (Bug#12302)
6990 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

7009 Handle click on close button as quit.
7011 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7012 Add window_closed and button_values. Add void as return value for
7013 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7014 Add process_dialog as new member.

7224 It was meant to be temporary and it often doesn't work,
7225 because when IDX has side effects the behavior of IDX==IDX
7226 is undefined. See Stefan Monnier in
7227 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.

7238 as that's faster and simpler than static storage. Don't bother
7239 with the g_main_context_query overhead if g_main_context_pending
7240 says no events are pending.
7241 (gfds, gfds_size): Remove these static vars.

7243 All uses and decls removed.

7275 * callint.c (Fcall_interactively): Don't assume the mark's
7276 offset fits in 'int'.

7286 (report_overlay_modification, call_overlay_mod_hooks):
7287 (mmap_enlarge, mmap_set_vars):
7288 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7289 Use bool for booleans, instead of int.
7290 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7291 since the 1-or-0 return value is always ignored anyway.
7292 (mmap_initialized_p):
7293 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7294 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7296 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7298 * bidi.c: Use bool for boolean.
7299 This is a bit more readable, and makes the text segment of bidi.o
7300 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7301 Presumably it's faster too.
7302 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

7308 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7309 Use bool for booleans, instead of int.
7310 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7311 (bidi_unshelve_cache): Adjust decls to match code.
7313 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7315 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7318 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7320 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7321 * atimer.h: Include <stdbool.h>.
7323 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7325 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7326 compile time tests instead of run time tests on systems that do
7328 (FRAME_MAC_P): Remove leftover from deleted code.
7329 * frame.c (syms_of_frame): Remove leftover from deleted code.
7331 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7333 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7335 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7337 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7338 Otherwise, the compiler complains about (A?B:C) where B is void
7339 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7340 (fontset_add): Return void, for FONTSET_ADD.
7342 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7344 * alloc.c: Use bool for booleans.
7345 (gc_in_progress, abort_on_gc)
7346 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7347 (dont_register_blocks) [GC_MALLOC_CHECK]:

7352 (mark_stack, valid_pointer_p, make_pure_string)
7353 (Fgarbage_collect, survives_gc_p, gc_sweep):
7354 Use bool for booleans, instead of int.
7355 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7356 Remove unused local.
7357 * alloc.c (PURE_POINTER_P):
7358 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7359 * editfns.c (Fformat):
7360 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7362 * fns.c (sweep_weak_table):
7363 * lisp.h (suppress_checking, push_message, survives_gc_p)
7364 (make_pure_string, gc_in_progress, abort_on_gc):
7365 * lread.c (readchar, read1):
7366 * print.c (Fprin1_to_string):
7367 * xdisp.c (push_message):
7368 Use bool for booleans affected directly or indirectly by
7371 Make recently-introduced setters macros.
7372 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7373 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7374 (set_fontset_default, set_fontset_fallback): Rename from their
7375 upper-case counterparts, and make them functions rather than macros.
7376 This is more consistent with the other recently-introduced setters.
7377 These don't need to be inline, since they're local.
7379 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7381 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7382 the loop (Bug#12247).
7384 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7386 * lisp.h (vcopy): Use memcpy rather than our own loop.
7387 This fixes a performance regression introduced by the recent
7388 addition of vcopy. This means 'vcopy' will need to be modified
7389 for a copying collector, but that's OK. Also, tighten the
7390 checking in the assertion.
7392 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7394 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7395 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7396 non-base glyph for the width of the base character, according to
7397 what x_draw_composite_glyph_string_foreground expects.
7398 Generate WADJUST value according to composition_gstring_width's
7399 expectations, to produce correct width of the composed character.
7400 Reverse the sign of the DU offset produced by ScriptPlace.
7402 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7404 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7406 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7408 Avoid direct writes to contents member of struct Lisp_Vector.
7409 * lisp.h (vcopy): New function to copy data into vector.
7410 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7411 * fns.c (Ffillarray): Use ASET.
7412 * keyboard.c (timer_check_2): Use AREF and ASET.
7413 (append_tool_bar_item, Frecent_keys): Use vcopy.
7414 * lread.c (read_vector): Use ASET.
7415 * msdos.c (Frecent_doskeys): Use vcopy.
7416 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7417 (Finternal_merge_in_global_face): Use ASET and vcopy.
7418 * xfont.c (xfont_list_pattern): Likewise.
7420 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7422 * window.c (Fwindow_point): For the selected window always return
7423 the position of its buffer's point.
7424 (Fset_window_point): For the selected window always go in its
7425 buffer to the specified position.
7427 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7429 Setter macros for fontsets.
7430 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7431 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7432 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7435 2012-08-20 Glenn Morris <rgm@gnu.org>
7437 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7438 Don't assume that `ln -f' works.
7440 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7442 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7443 and later about non-assignments with no effect. See discussion at
7444 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7447 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7449 Inline setter functions for Lisp_Objects slots of struct specbinding.
7450 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7453 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7455 * window.c (select_window): Always make selected window's buffer
7458 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7460 Use AREF and ASET for docstrings of category tables.
7461 * category.h (CATEGORY_DOCSTRING): Use AREF.
7462 (SET_CATEGORY_DOCSTRING): Use ASET.
7463 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7465 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7467 Inline setter functions for hash table members.
7468 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7469 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7470 (set_hash_key_and_value, set_hash_index, set_hash_next)
7471 (set_hash_hash): New functions.
7472 * charset.c, fns.c: Adjust users.
7474 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7476 Inline getter and setter functions for per-buffer values.
7477 * buffer.h (per_buffer_default, set_per_buffer_default)
7478 (per_buffer_value, set_per_buffer_value): New functions.
7479 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7480 * buffer.c, data.c: Adjust users.
7482 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7484 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7486 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7488 Rely on <config.h> + <unistd.h> to declare 'environ',
7489 as gnulib does this if the system doesn't.
7490 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7491 Remove declaration. MS-Windows declares it on stdlib.h which is
7492 included by conf_post.h.
7493 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7494 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7495 * vm-limit.c: Include <unistd.h>, for 'environ'.
7497 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7498 (start_of_data): Remove decl; mem-limits.h provides it.
7500 * xdisp.c (handle_invisible_prop): Make it a bit faster
7501 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7503 2012-08-19 Chong Yidong <cyd@gnu.org>
7505 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7508 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7510 * .gdbinit: Use call instead of set when calling a function in the
7513 * data.c (set_internal): Don't use set_blv_found.
7514 (Fkill_local_variable): Likewise.
7516 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7518 * nsfont.m (ns_ascii_average_width): Ensure the string
7519 ascii_printable is initialized with a null-terminated character
7520 array. Otherwise, it can contain undesired extra characters.
7522 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7524 port new setting code to Sun C 5.8 2005/10/13
7525 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7526 Return void, not Lisp_Object. Otherwise, the compiler
7527 complains about (A?B:C) where B is void and C is Lisp_Object
7528 when compiling CHAR_TABLE_SET, due to the recent change to
7529 the API of sub_char_table_set_contents.
7531 2012-08-18 Chong Yidong <cyd@gnu.org>
7533 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7534 for the string case (Bug#3874).

7617 are compiled into code.
7618 (tset_param_alist): New setter function.
7620 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>

7655 A few more naming-convention fixes for getters and setters.
7656 * buffer.c (set_buffer_overlays_before): Move here from buffer.h,

7658 (set_buffer_overlays_after): Move here from buffer.h, and rename
7659 from buffer_overlays_set_after.

7687 "CSET (XCHAR_TABLE (char_table), parent, parent);" with
7688 "set_char_table_parent (char_table, parent);".
7689 The old version was confusing because it used the same name
7690 'parent' for two different things.
7692 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
7694 Functions to get and set Lisp_Object fields of buffer-local variables.

7698 * data.c, eval.c, frame.c: Adjust users.
7700 2012-08-17 Chong Yidong <cyd@gnu.org>
7702 * xfaces.c (merge_face_vectors): If the target font specfies a
7703 font spec, make the font's attributes take precedence over
7704 directly-specified attributes.
7705 (merge_face_ref): Recognize :font.

8362 * w32.c (init_environment): Change the default values of many
8363 environment variables in dflt_envvars[] to NULL, to avoid pushing
8364 them into environment when they were not already defined.
8365 Remove the code that deletes site-lisp subdirectories from the default
8366 value of EMACSLOADPATH, as it is no longer needed.
8367 (check_windows_init_file): Now external, not static.
8368 Use Vload_path as is, without adding anything, as this function is now
8369 called when Vload_path is already set up.
8371 * w32.h (check_windows_init_file): Add prototype.
8373 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

8401 Remove unnecessary casts involving pointers.
8402 These casts are no longer needed now that we assume C89 or later,

8405 (make_pure_float, make_pure_vector):
8406 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

8416 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8417 Remove unnecessary pointer casts.
8418 * alloc.c (record_xmalloc): New function.
8419 * lisp.h (record_xmalloc): New decl.
8420 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8421 more like a function. This is because the pointer cast is not
8422 needed. All uses changed.
8423 * print.c (print_string, print_error_message): Avoid length recalc.
8425 Improve fix for macroexp crash with debugging (Bug#12118).
8426 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8427 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8428 not supposed to be invoked from the garbage collector.
8429 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
8430 (gc_aset): New function, which is like ASET but can be
8431 used in the garbage collector.

8447 headers (most versions of MinGW w32api don't).
8448 (get_security_info, create_symbolic_link)
8449 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
8451 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
8452 in the argument file name.

8455 (sys_rename): Diagnose renaming of a symlink when the user doesn't
8456 have the required privileges.
8457 (get_file_security_desc_by_name): Rename from
8458 get_file_security_desc.
8459 (stat_worker): New function, with most of the guts of 'stat', and
8460 with addition of handling of symlinks and support for 'lstat'.
8461 If possible, get file's attributes and security information by
8462 handle, not by name. Produce S_IFLNK bit for symlinks, when
8463 called from 'lstat'.
8464 (stat, lstat): New functions, call 'stat_worker'.
8465 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8466 symlinks when the underlying filesystem supports them.
8468 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8470 Fix macroexp crash on Windows with debugging (Bug#12118).
8471 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8472 checking subscripts; problem introduced with the recent
8473 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8474 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8475 since it's used in non-static inline functions now.
8477 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8478 Don't assume buffer size fits in 'int'. Remove unused local.

8495 * category.c (CATEGORY_INLINE):
8496 * character.c (CHARACTER_INLINE):
8497 * charset.c (CHARSET_INLINE):
8498 * composite.c (COMPOSITE_INLINE):
8499 * dispnew.c (DISPEXTERN_INLINE):
8500 * sysdep.c (SYSTIME_INLINE):
8501 Define to EXTERN_INLINE, so that the corresponding functions
8502 are compiled into code.
8503 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8504 (INLINE_HEADER_END): New macros.
8505 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8525 hard-coding the path separator.
8527 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8529 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8530 This how ASET and AREF are supposed to work, and makes
8531 it easier to think about future improvements. See
8532 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8533 * charset.h (set_charset_attr): New function.

9025 the fix for 12036 would have avoided some of the problems noted in

9048 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9049 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9050 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9051 Adjust to changes in lisp.h and emacs.c, by using
9052 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9053 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9054 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9055 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9056 instead of gdb_valbits.
9057 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9058 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9059 instead of gdb_array_mark_flag.
9060 (xboolvector): Get size from $->size, not $->header.size.
9061 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9062 (xreload, hook-run, hookpost-run): Remove.
9063 * emacs.c: Include <verify.h>.
9064 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)

9072 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

9077 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9078 more convenient now. All uses changed.
9079 (VALMASK) [USE_LSB_TAG]: Also define in this case.

9095 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9096 than macros. This simplifies debugging in the usual case, since
9097 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9098 and it allows expressions involving EMACS_INT casts.
9099 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9101 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

9153 Swap buffer text indirection counters in Fbuffer_swap_text.
9154 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9155 This avoids crash reported by Christoph Scholtes at
9156 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9158 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9160 * nsmenu.m (Popdown_data): New struct.

9185 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9186 as it's limited by the amount of memory, not by INT_MAX.

9964 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9965 * nsterm.m (ns_term_init):
9966 Avoid the need for strncpy, by using build_string or
9967 make_unibyte_string directly. Use dtoastr, not snprintf.
9968 * process.c (Fmake_network_process): Diagnose service names that
9969 are too long, rather than silently truncating them or creating
9970 non-null-terminated names.
9971 (Fnetwork_interface_info): Likewise, for interface names.
9972 * sysdep.c (system_process_attributes) [GNU_LINUX]:
9973 Prefer sprintf to strncat.

9980 Clarify fallback case.
9982 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

9985 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
9986 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
9987 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9988 where argument type is known to be a Lisp_Cons.
9990 2012-07-10 Tom Tromey <tromey@redhat.com>
9992 * bytecode.c (BYTE_CODE_THREADED): New macro.

10000 Optimize pure C strings initialization.
10001 * lisp.h (make_pure_string): Fix prototype.
10002 (build_pure_c_string): New function, defined as static inline. This
10003 provides a better opportunity to optimize away calls to strlen when
10004 the function is called with compile-time constant argument.
10005 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10006 argument, adjust users accordingly. Use build_pure_c_string where
10008 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
10009 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10010 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
10012 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10014 Avoid calls to strlen in miscellaneous functions.
10015 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
10016 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
10017 * lread.c (openp): Likewise.
10019 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10021 Avoid calls to strlen in path processing functions.
10022 * fileio.c (file_name_as_directory): Add comment. Change to add
10023 srclen argument and return the length of result. Adjust users
10025 (directory_file_name): Fix comment. Change to add srclen argument,
10026 swap 1st and 2nd arguments to obey the common convention.
10027 Adjust users accordingly.
10028 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
10030 2012-07-10 Glenn Morris <rgm@gnu.org>

10033 Move PENDING_OUTPUT_COUNT definition to configure.
10035 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
10036 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
10037 * s/gnu.h (DATA_START): Move definitions to configure.
10039 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10040 We include usg5-4-common.h, which defines them both.
10042 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10043 O_RDONLY already includes it).
10045 Stop ns builds setting the EMACSLOADPATH environment variable.
10046 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10047 Now it does not set EMACSLOADPATH, just returns the load-path string.
10048 * nsterm.h: Update accordingly.
10049 * lread.c [HAVE_NS]: Include nsterm.h.
10050 (init_lread) [HAVE_NS]: Use ns_load_path.
10051 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10053 2012-07-09 Glenn Morris <rgm@gnu.org>
10055 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10056 since the included bsd-common.h does so.
10058 Stop ns builds setting the EMACSPATH environment variable.
10059 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10060 (ns_init_paths): Do not set EMACSPATH.
10061 * nsterm.h (ns_exec_path): Add it.
10062 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10065 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10067 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10069 * process.c (wait_reading_process_output): 'waitchannels' was unset
10070 when read_kbd || !NILP (wait_for_cell); fix this.
10072 Add GCC-style 'const' attribute to functions that can use it.
10073 * character.h (char_resolve_modifier_mask):
10074 * keyboard.h (make_ctrl_char):
10075 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10076 (init_character_once, next_almost_prime, init_fns, init_image)
10077 (flush_pending_output, init_sound):

10086 Minor improvements to make_formatted_string.
10087 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10088 where int is good enough, as vsprintf returns an int.
10089 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10091 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10093 Use make_formatted_string to avoid double length calculation.
10094 * lisp.h (make_formatted_string): New prototype.

10116 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10118 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10120 Move marker debugging code under MARKER_DEBUG.
10121 * marker.c (MARKER_DEBUG): Move marker debugging code under
10122 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10123 for bootstrap with --enable-checking (~3x slowdown reported
10124 by Juanma Barranquero <lekktu@gmail.com>).
10125 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10127 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10129 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10130 See <http://bugs.gnu.org/11825#29>.
10132 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10134 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10135 has no font, use the frame's font. (Bug#11813)
10136 (display_line): Add commentary about displaying truncation glyphs
10138 (produce_special_glyphs): Move here from term.c.
10140 * term.c (produce_special_glyphs): Move to xdisp.c.
10142 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10145 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10147 * xdisp.c (display_line): Avoid warning about implicit declaration
10150 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10152 * lisp.h: Remove empty conditional.
10154 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10156 * lread.c (load_path_check): Now static.
10158 Fix some minor --with-ns problems found by static checking.
10159 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10160 (x_set_font) [!HAVE_X_WINDOWS]:
10161 * image.c (xpm_load_image) [HAVE_NS]:
10162 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10163 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10164 Remove unused local.
10165 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10166 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10167 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10168 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10169 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10170 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10171 Fix pointer signedness problem.
10172 * xfaces.c (FRAME_X_FONT_TABLE):
10173 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10175 2012-07-07 Glenn Morris <rgm@gnu.org>
10177 * lread.c (load_path_check): New function, split from init_lread.
10178 (init_lread): Reorganize. Motivation:
10179 If EMACSLOADPATH is set, check/warn about that rather than the
10180 defaults, which we are not going to use. Hence we can remove
10181 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10182 Don't warn if site-lisp directories are missing.
10183 If not installed, start from a blank load-path, since
10184 PATH_LOADSEARCH refers to the eventual installation directories.
10186 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10188 Support truncation and continuation glyphs on GUI frames, when
10189 fringes are disabled. (Bug#11832)
10190 * xdisp.c (init_iterator): Get dimensions of truncation and
10191 continuation glyphs even if on GUI frames.
10192 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10193 or both, are absent.
10194 (start_display, move_it_in_display_line_to): Handle the case of a
10195 GUI frame without a fringe to display continuation or truncation
10197 (insert_left_trunc_glyphs): Support GUI frames: make sure
10198 truncation glyphs overwrite enough glyphs from the current line to
10199 have sufficient space in pixels.
10200 (display_line): Support truncation and continuation glyphs on GUI
10201 frames. If some spare pixels are left on the line after inserting
10202 the truncation glyphs, fill that space with a stretch glyph of a
10203 suitably computed width.
10205 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10206 produce_glyphs, to support GUI sessions.
10208 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10210 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10212 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10214 Do not require float-time's arg to fit in time_t (Bug#11825).
10215 This works better on hosts where time_t is unsigned, and where
10216 float-time is applied to the (negative) difference between two times.
10217 * editfns.c (decode_time_components): Last arg is now double *,
10218 not int *, and means to store all the result as a double, without
10219 worrying about whether the seconds part fits in time_t.
10220 All callers changed.
10221 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10222 All callers changed.
10223 (Ffloat_time): Do not fail merely because the specified time falls
10224 outside of time_t range.
10226 2012-07-07 Glenn Morris <rgm@gnu.org>
10228 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10229 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10230 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10232 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10234 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10235 Update dependencies.
10237 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10239 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10241 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
10242 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
10243 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10244 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10245 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10246 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10248 * xfont.c (compare_font_names): Redo to omit the need for casts.
10250 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10252 * xfns.c (Fx_change_window_property): Doc fix.
10253 * w32fns.c (Fx_change_window_property): Doc fix.
10255 * w32fns.c (Fx_window_property): Accept the same arguments as the
10256 X Windows version. Doc fix.
10257 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10259 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10260 Eli Zaretskii <eliz@gnu.org>
10262 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10263 Windows-specific code from nt/config.nt moved here.
10264 Obsolete settings removed.
10266 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10268 * process.c: Avoid unnecessary calls to gettime.
10269 (wait_reading_process_output): Don't get the time of day
10270 when gobbling data immediately and not waiting, as there's no need
10271 for it in that case. This removes a FIXME.
10273 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10275 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10276 is defined (Bug#11768).
10278 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10280 Fix marker debugging code.
10281 * marker.c (byte_char_debug_check): Do not perform the check
10282 if buffer is not multibyte.
10283 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10284 Call byte_char_debug_check with correct arguments.
10286 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10288 Compile marker debugging code only if ENABLE_CHECKING is defined.
10289 * marker.c (byte_char_debug_check, count_markers):
10290 Use only if ENABLE_CHECKING is defined.
10291 (byte_debug_flag): Remove.
10292 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10293 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10295 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10297 Avoid code repetition in marker-related functions.
10298 * marker.c (attach_marker): New function.
10299 (Fset_marker, set_marker_restricted, set_marker_both)
10300 (set_marker_restricted_both): Use it.
10301 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
10302 Consistently rename charno to charpos.
10303 (marker_position): Add eassert.
10304 (marker_byte_position): Convert to eassert.
10306 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10308 Simplify list operations in unchain_overlay and unchain_marker.
10309 * buffer.c (unchain_overlay): Simplify. Add comment.
10310 * marker.c (unchain_marker): Simplify. Fix comments.
10312 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10314 Introduce fast path for the widely used marker operation.

10316 * lisp.h (build_marker): New prototype.
10317 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
10318 * composite.c (autocmp_chars): Likewise.
10319 * editfns.c (buildmark): Remove.
10320 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10321 (save_restriction_save): Use build_marker.
10322 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10323 * window.c (save_window_save): Likewise.
10325 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10327 Do not use Fdelete_overlay in delete_all_overlays
10328 to avoid redundant calls to unchain_overlay.
10329 * buffer.c (drop_overlay): New function.
10330 (delete_all_overlays, Fdelete_overlay): Use it.
10331 * minibuf.c (get_minibuffer): Fix comment.
10333 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10335 Port to OpenBSD 5.1 amd64.
10336 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10337 This is needed for OpenBSD, and should be harmless on all BSD systems.
10338 Also, include <sys/sysctl.h>, as it should be available on all
10339 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10340 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10341 use p_pid member, not kp_proc.pid.
10343 2012-07-06 Glenn Morris <rgm@gnu.org>
10345 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10347 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10349 More xmalloc and related cleanup.
10350 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
10351 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
10352 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
10353 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
10354 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
10355 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
10356 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
10357 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
10358 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10360 Omit needless casts involving void * pointers and allocation.
10361 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10362 as the former is more robust if P's type is changed.
10363 Prefer xzalloc to xmalloc + memset 0.
10364 Simplify malloc-or-realloc to realloc.
10365 Don't worry about xmalloc returning a null pointer.
10366 Prefer xstrdup to xmalloc + strcpy.
10367 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10369 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10370 alloca of a constant.
10372 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10374 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10375 hscroll is larger than the line width. Fixes long and futile
10376 looping inside extend_face_to_end_of_line (on a TTY) producing
10377 glyphs that are not needed and thrown away.
10379 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10381 * marker.c (set_marker_restricted_both): Simplify by using
10384 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10386 * editfns.c (region_limit): Simplify by using clip_to_bounds.

10390 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
10391 not defined (Bug#11768).
10392 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
10393 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)

10401 (xg_tool_item_stale_p): Call is_box_type.
10402 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10403 with default display (Bug#11768).
10405 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10407 * xdisp.c (window_hscroll_limited): New function.
10408 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10409 coordinates when window's hscroll is set to insanely large
10410 values. (Bug#11857)
10412 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10475 * fileio.c (time_error_value): Check the right error number.
10476 Problem reported by Troels Nielsen in
10477 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10479 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10481 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10482 This should be fixed in a better way; see Eli Zaretskii in
10483 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10484 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10486 * fileio.c (time_error_value): Rename from special_mtime.
10487 The old name's problems were noted by Eli Zaretskii in
10488 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10490 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10491 This variable's comment says Emacs needs at least one GDB-visible
10492 symbol of type enum pvec_type, to work around GDB problems.
10493 The symbol's value doesn't matter.
10495 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10496 that causes compilation to fail on pre-C99 compilers.
10498 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10500 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

10506 headers for buffer_defaults and buffer_local_symbols.
10507 Reported by Juanma Barranquero <lekktu@gmail.com>.
10509 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>

10513 (PSEUDOVECTOR_SIZE_BITS): New constant.
10514 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10515 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10516 change in pvec_type.
10517 (PSEUDOVECTOR_TYPEP): New macro.
10518 (TYPED_PSEUDOVECTORP): Use it.
10519 * fns.c (internal_equal): Adapt code to extract pvectype.
10520 * emacs.c (gdb_pvec_type): Update type.
10521 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10522 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10523 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10524 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10525 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10526 abusing vector->header.next.nbytes.
10527 (live_vector_p): Use PVEC_TYPE.
10528 (mark_object): Adapt code to extract pvectype. Use switch.
10530 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10532 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10533 Tighten new eassert a bit.
10535 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10537 Fix compilation with --enable-gcc-warnings and -O1
10538 optimization level.
10539 * doprnt.c (doprnt): Change type of tem to int, initialize
10540 to avoid compiler warning. Add eassert.
10541 * search.c (simple_search): Initialize match_byte to avoid
10542 compiler warning. Add eassert.
10544 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10546 Avoid weird behavior with large horizontal scrolls.
10547 Without this change, for example, large hscroll values would
10548 mess up Emacs's display on Fedora 15 x86, presumably due to
10549 overflows in int calculations in the display code.
10550 Also, if buffers had long lines, Emacs would freeze.
10551 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10552 (set_window_hscroll): New function, containing the old guts of
10553 Fset_window_hscroll. Return the clipped value.
10554 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10555 This avoids the need to check against PTRDIFF_MAX.
10557 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10559 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10561 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10563 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10565 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10566 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10567 since GCC 4.4.6 issues a bogus warning for them.
10569 Fix bugs in file timestamp newness comparisons.
10570 * fileio.c (Ffile_newer_than_file_p):
10571 * lread.c (Fload): Use full timestamp resolution of files,
10572 not just the 1-second resolution, so that files that are only
10573 slightly newer still count as newer.
10574 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10575 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10577 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10579 * fileio.c: Improve handling of file time marker. (Bug#11852)
10580 (special_mtime): New function.
10581 (Finsert_file_contents, Fverify_visited_file_modtime):
10582 Use it to set special mtime values consistently.
10584 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10586 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10587 marker for non-existing file. (Bug#11852)
10589 2012-07-03 Glenn Morris <rgm@gnu.org>
10591 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10592 and did not make it into globals.h).
10594 2012-07-03 Tom Tromey <tromey@redhat.com>
10596 * window.c (Fset_window_margins, Fset_window_fringes)
10597 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10598 * textprop.c (Fprevious_property_change): No longer static.

10627 * w32term.h: Remove EXFUNs.

10630 * xterm.h: Remove EXFUN.
10632 2012-07-03 Glenn Morris <rgm@gnu.org>
10634 * lisp.h (Frandom): Make it visible to C.
10635 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10636 buffer for invisible buffers. (Bug#1229)
10638 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10640 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10641 values which aren't power of 2.
10642 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10643 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10646 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10648 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10650 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10652 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10654 * alloc.c (allocate_vector_block): Remove redundant
10655 calls to mallopt if DOUG_LEA_MALLOC is defined.
10656 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10657 avoid calls to mallopt if zero_vector is returned.
10659 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10661 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10662 is enabled, avoid dereferencing NULL current_sblock if
10665 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10667 Cleanup basic buffer management.
10668 * buffer.h (struct buffer): Change layout to use generic vector
10669 marking code. Fix some comments. Change type of 'clip_changed'
10670 to bitfield. Remove unused #ifndef old.
10671 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10672 (GET_OVERLAYS_AT): Fix indentation.
10673 (for_each_per_buffer_object_at): New macro.
10674 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

10678 struct buffer. Fix comment.
10679 (mark_overlay): New function.
10680 (mark_buffer): Use it. Use mark_vectorlike to mark normal

10682 (mark_object): Use it. Adjust marking of misc objects
10683 and related comments.
10685 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10687 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10688 wrapper that is not needed because the wrapped code is a no-op (zero
10689 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10690 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10692 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10694 * alloc.c (mark_buffer): Simplify. Remove prototype.
10695 (mark_object): Add comment. Reorganize marking of vector-like
10696 objects. Use CHECK_LIVE for all vector-like objects except buffers
10697 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10698 Avoid redundant calls to mark_vectorlike for bool vectors.
10700 2012-06-30 Glenn Morris <rgm@gnu.org>
10702 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10704 * epaths.in (PATH_SITELOADSEARCH): New.
10705 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10706 This is rather than relying on --enable-locallisppath elements
10707 having "site-lisp" in their names. (Bug#10208#25, 11658)
10709 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10711 * w32proc.c (sys_select): Accept and ignore one more argument.
10713 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10715 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10716 (pselect) [!MS_DOS]: Redirect to sys_select.
10718 * sysdep.c: Don't include dos.h and dosfns.h.
10720 * process.c (sys_select):
10721 * msdos.c (sys_select): Accept one more argument and ignore it.
10723 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10724 adapt data types and code to that.
10727 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10728 which clashes with the gnulib function of the same name.
10730 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10732 * font.c (font_style_to_value, font_style_symbolic)
10733 (font_prop_validate_style): Add type checks for values in
10736 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10738 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10741 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10743 * xdisp.c (try_window_id): Undo last change.
10745 * w32.c (getwd): Adjust commentary about startup_dir.
10746 (init_environment): Always call sys_access, even in non-MSVC
10747 builds. Don't chdir to the directory of the Emacs executable.
10748 This undoes code from 1997 which was justified by the need to
10749 "avoid conflicts when removing and renaming directories". But its
10750 downside was that every relative file name was being interpreted
10751 relative to the directory of the Emacs executable, which can never
10752 be TRT. In particular, it broke sys_access when called with
10753 relative file names.
10754 (sys_access): Map GetLastError to errno.
10756 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

10762 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10765 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10767 * gnutls.c (emacs_gnutls_handshake):
10768 Add QUIT to make the loop interruptible.
10770 2012-06-29 Glenn Morris <rgm@gnu.org>
10772 * charset.c (init_charset): Make lack of etc/charsets fatal.
10774 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10776 * editfns.c (region_limit): Fix type mismatch.
10778 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10780 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10781 undefined. Convert from xassert to eassert.
10782 * nsmenu.m: Convert from xassert to eassert.
10783 * nsterm.m: Likewise.
10785 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
10787 * editfns.c (region_limit): Clip to narrowing (bug#11770).
10789 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10791 Avoid integer overflow on scroll-left and scroll-right.
10792 * window.c (HSCROLL_MAX): New macro.
10793 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10794 overflow when requested scroll falls outside ptrdiff_t range.
10796 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10798 * window.h (struct window): Change type of 'hscroll',
10799 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10800 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10801 Adjust users accordingly.
10802 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10803 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10804 from EMACS_INT to ptrdiff_t.
10805 (make_window): Omit redundant initialization.
10807 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
10809 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
10811 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10813 * window.h (struct window): Change type of 'use_time' and
10814 'sequence_number' from Lisp_Object to int.
10815 * frame.c (make_frame): Adjust users accordingly.
10816 * print.c (print_object): Likewise.
10817 * window.c (select_window, Fwindow_use_time, make_parent_window)
10818 (make_window): Likewise.
10820 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10822 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
10823 enabled with --enable-checking=[all,glyphs] configure option.
10824 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10825 adjust comments accordingly.

10948 Use sprintf return value instead of invoking strlen on result.
10949 In the old days this wasn't portable, since some sprintf
10950 implementations returned char *. But they died out years ago and
10951 Emacs already assumes sprintf returns int.
10952 Similarly for float_to_string.
10953 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10961 Use sprintf or float_to_string result to avoid need to call strlen.
10962 * data.c (Fnumber_to_string):
10963 Use make_unibyte_string, since the string must be ASCII.
10964 * lisp.h, print.c (float_to_string): Now returns int length.
10965 * term.c (produce_glyphless_glyph):
10966 Use sprintf result rather than recomputing it.
10968 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

11001 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

11067 * keyboard.c (kbd_buffer_get_event):
11068 * process.c (Faccept_process_output):
11069 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11070 This improves on the previous patch, which introduced a bug
11071 when time_t is unsigned and as wide as intmax_t.
11072 See <http://bugs.gnu.org/9000#51>.
11074 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11103 language ID in the event parameters.
11105 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11106 event.code, not the obscure "character set ID".
11108 2012-06-23 Chong Yidong <cyd@gnu.org>

11137 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
11139 Support higher-resolution time stamps (Bug#9000).
11140 The time stamps are only nanosecond-resolution at the C level,
11141 since that's the best that any real-world system supports now.
11142 But they are picosecond-resolution at the Lisp level, as that's
11143 easy, and leaves room for future OS improvements.
11145 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11148 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11149 Don't get current time unless it's needed.
11151 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11152 now provides it if it's absent.
11153 (start_atimer): Port to higher-res time stamps.
11154 Check for time stamp overflow. Don't get current time more
11155 often than is needed.
11157 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11158 Include systime.h, not time.h.
11159 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11161 * dired.c: Include stat-time.h.
11162 (Ffile-attributes): File times now have higher resolution.
11164 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11165 (struct image): Timestamp now has higher resolution.
11167 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11168 has at least microseconds now. All uses removed.
11169 (update_frame, update_single_window, update_window, update_frame_1)
11170 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11171 (duration_to_sec_usec): Remove; no longer needed.
11173 * editfns.c (time_overflow): Now extern.
11174 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
11175 (float-time, Fformat_time_string, Fcurrent_time_string)

11178 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
11179 (decode_time_components, lisp_seconds_argument): New functions.
11180 (make_time): Now static.
11181 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11182 Report an error if the time is invalid, rather than having the caller
11185 * fileio.c: Include <stat-time.h>
11186 (Fcopy_file): Copy higher-resolution time stamps.
11187 Prefer to set the time stamp via a file descriptor if that works.
11188 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11189 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11190 (Fvisited_file_modtime, Fset_visited_file_modtime):
11191 Support higher-resolution time stamps.
11193 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11195 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11197 * image.c (prepare_image_for_display, clear_image_cache)
11198 (lookup_image): Port to higer-resolution time stamps.
11200 * keyboard.c (start_polling, bind_polling_period):
11201 Check for time stamp overflow.
11202 (read_char, kbd_buffer_get_event, timer_start_idle)
11203 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11204 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11205 Port to higher-resolution time stamps. Do not assume time_t is signed.
11206 (decode_timer): New function. Timers are now vectors of length 9,
11207 not 8, to accommodate the picosecond component.
11208 (timer_check_2): Use it.
11210 * nsterm.m (select_timeout, timeval_subtract): Remove.
11211 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11212 as they're a bit more accurate and handle overflow better.
11213 (ns_select): Change prototype to be compatible with pselect.
11214 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11215 * nsterm.h (ns_select): Adjust prototype.
11217 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11218 us-resolution time stamps.
11219 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11221 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11223 * lisp.h (time_overflow): New decl.
11224 (wait_reading_process_output): First arg is now intmax_t, not int,
11225 to accommodate larger waits.
11227 * process.h (struct Lisp_Process.read_output_delay):
11228 Now counts nanoseconds, not microseconds.
11229 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11231 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11232 (wait_reading_process_output):
11233 Port to ns-resolution time stamps.
11234 (Faccept_process_output, wait_reading_process_output):
11235 Check for time stamp overflow. Do not assume time_t is signed.
11236 (select_wrapper): Remove; we now use pselect.
11237 (Fprocess_attributes): Now generates ns-resolution time stamps.
11239 * sysdep.c: Include utimens.h. Don't include utime.h
11240 or worry about struct utimbuf; gnulib does that for us now.
11241 (gettimeofday): Remove; gnulib provides a substitute.
11242 (make_timeval): New function.
11243 (set_file_times): Now sets ns-resolution time stamps.
11244 New arg FD; all uses changed.
11245 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11246 (system_process_attributes):
11247 Now returns ns-resolution time stamp. All uses changed.
11248 Check for time stamp overflow.
11250 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11251 provides a substitute now.
11253 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11254 since it guarantees struct timespec.
11255 (EMACS_TIME): Now struct timespec, so that we can support
11256 ns-resolution time stamps.
11257 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11258 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11259 (EMACS_USECS): Remove.
11260 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11261 so multiply the arg by 1000 before storing it.
11262 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11264 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11265 Port to ns-resolution time stamps.
11266 (EMACS_TIME_NEG_P): Remove; replaced by....
11267 (EMACS_TIME_SIGN): New macro.
11268 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
11269 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
11270 (set_file_times, make_time, lisp_time_argument): Adjust signature.
11271 (make_timeval, make_lisp_time, decode_time_components): New decls.
11272 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11273 that it mishandled time_t overflow. You can't compare by subtracting!
11274 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11275 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11277 * term.c: Include <sys/time.h>.
11278 (timeval_to_Time): New function, for proper overflow wraparound.
11279 (term_mouse_position, term_mouse_click): Use it.
11281 * undo.c (record_first_change): Support higher-resolution time stamps
11282 in the undo buffer.

11730 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
11732 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
11734 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11736 * doprnt.c (doprnt): Truncate multibyte char correctly.
11737 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11738 would mishandle a string argument "Xc" if X was a multibyte
11739 character of length 2: it would truncate after X's first byte
11740 rather than including all of X.
11742 2012-06-06 Chong Yidong <cyd@gnu.org>
11744 * buffer.c (word_wrap): Doc fix.
11746 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

11754 2012-06-03 Ulrich Müller <ulm@gentoo.org>
11756 * Makefile.in (PAXCTL): Define.
11757 (temacs$(EXEEXT)): Disable memory randomization for the temacs
11758 binary via PaX flags if the paxctl utility is available.
11759 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
11760 Restore PaX flags to their default. (Bug#11398)
11762 2012-06-03 Chong Yidong <cyd@gnu.org>
11764 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
11765 buffer (Bug#11226).

11769 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
11770 (note_mode_line_or_margin_highlight): If there is no help echo,
11771 use mode-line-default-help-echo. Handle the case where the mouse
11772 position is past the end of the mode line string.
11774 * buffer.c (buffer_local_value_1): New function, split from
11775 Fbuffer_local_value; can return Qunbound.
11776 (Fbuffer_local_value): Use it.
11777 (Vmode_line_format): Docstring tweaks.
11779 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
11781 * sysdep.c (system_process_attributes): Improve comment.
11783 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
11785 * keyboard.c: Export real-this-command to Elisp.
11786 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
11787 and DEFVAR it. Update all users.
11789 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
11791 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11793 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11794 Convert pctcpu and pctmem to Lisp float properly.
11795 Let the compiler fold better, as 100.0/0x8000 is exact.
11797 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11799 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11802 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
11804 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
11806 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11808 For a 'struct window', replace some Lisp_Object fields to
11809 bitfields where appropriate, remove unused fields.
11810 * window.h (struct window): Remove unused 'last_mark_x' and
11811 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11812 change its type from Lisp_Object to bitfield.
11813 Change type of 'force_start', 'optional_new_start',
11814 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11815 fields from Lisp_Object to bitfield. Adjust users accordingly.
11817 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11819 Pacify gcc -Wdouble-precision when using Xaw.
11820 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11821 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11822 Use 'float' consistently, rather than 'float' in most places
11823 and 'double' in a couple of places.
11825 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11827 * xdisp.c (handle_stop): Detect whether we have overlay strings
11828 loaded by testing it->current.overlay_string_index to be
11829 non-negative, instead of checking whether n_overlay_strings is
11830 positive. (Bug#11587)
11832 2012-05-31 Chong Yidong <cyd@gnu.org>
11834 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
11836 * doc.c (Fsubstitute_command_keys): Doc fix.
11838 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11840 * search.c (search_buffer): Remove calls to
11841 r_alloc_inhibit_buffer_relocation, as it is now called by
11842 maybe_unify_char, which was the cause of relocation of buffer text
11845 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11847 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11848 for the duration of call to load_charset, to avoid problems with
11849 callers of maybe_unify_char that access buffer text through C
11852 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11853 decrement the inhibition flag, instead of just setting or
11856 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11858 Remove obsolete '#define static' cruft.
11859 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11860 This #undef was "temporary" in 2000; it is no longer needed
11861 now that '#define static' has gone away.
11862 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11863 (gray_bitmap_bits): Remove; no longer needed.
11864 All uses replaced with definiens.
11865 * xterm.c: Include "bitmaps/gray.xbm".
11867 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11869 Clean up __executable_start, monstartup when --enable-profiling.
11870 The following changes affect the code only when profiling.
11871 * dispnew.c (__executable_start): Rename from safe_bcopy.
11872 Define only on platforms that need it.
11873 * emacs.c: Include <sys/gmon.h> when profiling.
11874 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11875 (__executable_start): Remove decl, since lisp.h does it now.
11876 (safe_bcopy): Remove decl; no longer has that name.
11877 (main): Coalesce #if into single bit of code, for simplicity.
11878 Cast pointers to uintptr_t, since standard libraries want integers
11880 * lisp.h (__executable_start): New decl.
11882 2012-05-31 Glenn Morris <rgm@gnu.org>
11884 * image.c (Fimagemagick_types): Doc fix.
11886 2012-05-30 Jim Meyering <meyering@redhat.com>
11888 * callproc.c (Fcall_process_region): Include directory component
11889 in mkstemp error message (Bug#11586).
11891 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
11893 * alloc.c, lisp.h (make_pure_vector): Now static.
11895 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

11901 (Qdefun): Move from eval.c.
11902 * lisp.h (Qdefun): Remove.
11903 * lread.c (read1): Tiny simplification.
11905 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11907 Do not create empty overlays with the evaporate property (Bug#9642).
11908 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11909 Bug#9642, but explicitly check that the buffer the overlay would
11910 be moved to is live and rearrange lines to make sure that errors
11911 will not put the overlay in an inconsistent state.
11912 (Fdelete_overlay): Cosmetics.
11914 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11916 * w32term.c (my_bring_window_to_top): New function.
11917 (x_raise_frame): Use handle returned by DeferWindowPos, which
11918 could be different from the original one.
11919 Call my_bring_window_to_top instead of my_set_foreground_window.
11922 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP

11928 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11930 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11931 This avoids undefined behavior that might cause the eassert
11932 to not catch an out-of-range value.
11934 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11936 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
11937 Update dependencies.
11939 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11941 * bidi.c (bidi_mirror_char): Fix last change.
11943 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

11946 when referring to sectname field in printf format.
11948 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11950 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11951 Only r_alloc_inhibit_buffer_relocation needed to be added;
11952 the others were already declared.
11954 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11955 before checking whether it's out of range. Put the check inside
11957 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11959 2012-05-27 Ken Brown <kbrown@cornell.edu>
11961 * callproc.c (Fcall_process): Restore a line that was accidentally
11962 commented out in the 2011-02-13 change (bug#11547).
11964 2012-05-27 Eli Zaretskii <eliz@gnu.org>
11966 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11967 defined on ralloc.c.
11969 * buffer.c [REL_ALLOC]: Remove prototypes of
11970 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11971 they are now on lisp.h.
11973 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11975 * search.c (search_buffer): Use it to inhibit relocation of buffer
11976 text while re_search_2 is doing its job, because re_search_2 is
11977 passed C pointers to buffer text. (Bug#11519)
11979 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11980 Update value to 24.
11982 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11983 state after an additional call to move_it_in_display_line_to, keep
11984 the values of it->max_ascent and it->max_descent found for the
11986 (pos_visible_p): Revert the comparison against bottom_y to what it
11987 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11990 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11992 Fix coding-related core dumps with gcc -ftrapv.
11993 The code was computing A - B, where A and B are pointers, and B is
11994 random garbage. This can lead to core dumps on platforms that
11995 have special pointer registers, and it also leads to core dumps on
11996 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11997 A - B only when B is initialized properly.
11998 * coding.c (coding_set_source, coding_set_destination): Return void.
11999 (coding_change_source, coding_change_destinations): New functions,
12000 with the old behaviors of coding_set_source and coding_set_destination.
12001 All callers that need an offset changed to use these new functions.
12003 2012-05-26 Glenn Morris <rgm@gnu.org>
12005 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
12007 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12009 Extend mouse support on W32 text-mode console.
12010 * xdisp.c (draw_row_with_mouse_face):
12011 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12013 * w32console.c: Include window.h.
12014 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12016 (initialize_w32_display): Initialize mouse-highlight data.
12018 * w32inevt.c: Include termchar.h and window.h.
12019 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12020 moves, call note_mouse_highlight. If help_echo changed, call
12021 gen_help_event to produce help-echo message in the echo area.
12022 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12025 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12027 * lread.c (read1): Simplify slightly to avoid an overflow warning
12028 with GCC 4.7.0 on x86-64.
12030 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12032 * bidi.c (bidi_mirror_char): Revert last change: an int is
12033 definitely wide enough here.
12035 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12037 Fix integer width and related bugs (Bug#9874).

12044 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
12045 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
12047 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12048 (allocate_pseudovector):
12049 Use int, not EMACS_INT, where int is wide enough.
12050 (inhibit_garbage_collection, Fgarbage_collect):
12051 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12052 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12053 int might not be wide enough.
12054 (bidi_cache_search, bidi_cache_find, bidi_init_it)
12055 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
12056 (bidi_at_paragraph_end, bidi_find_paragraph_start)
12057 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
12058 (bidi_level_of_next_char, bidi_move_to_visually_next):
12059 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12060 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
12061 (Fkill_buffer, Fset_buffer_major_mode)
12062 (advance_to_char_boundary, Fbuffer_swap_text)
12063 (Fset_buffer_multibyte, overlays_at, overlays_in)
12064 (overlay_touches_p, struct sortvec, record_overlay_string)
12065 (overlay_strings, recenter_overlay_lists)
12066 (adjust_overlays_for_insert, adjust_overlays_for_delete)
12067 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
12068 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
12069 (Foverlay_recenter, last_overlay_modification_hooks_used)
12070 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
12071 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12072 (validate_region): Omit unnecessary test for b <= e,
12073 since that's guaranteed by the previous test.
12074 (adjust_overlays_for_delete): Avoid pos + length overflow.
12075 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12076 (report_overlay_modification):
12077 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12078 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12079 Omit pointer cast, which isn't needed anyway, and doesn't work
12080 after the EMACS_INT -> ptrdiff_t change.
12081 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12082 * buffer.h: Adjust decls to match defn changes elsewhere.
12083 (struct buffer_text, struct buffer):
12084 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12085 Use EMACS_INT, not int, where int might not be wide enough.
12086 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12087 not int, to avoid needless 32-bit limit on 64-bit hosts.
12088 (exec_byte_code): Use tighter memory-full test, one that checks
12089 for alloca overflow. Don't compute the address of the object just
12090 before an array, as that's not portable. Use EMACS_INT, not
12091 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12092 * callint.c (Fcall_interactively):
12093 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12094 * callproc.c (call_process_kill, Fcall_process):
12095 Don't assume pid_t fits into an Emacs fixnum.

12103 * casefiddle.c (casify_object, casify_region, operate_on_word)
12104 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
12105 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12106 (casify_object): Avoid integer overflow when overallocating buffer.
12107 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12108 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12109 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12110 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12111 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
12112 integers are now checked earlier. All uses replaced with XINT.
12114 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12115 For CCL_MapSingle, check that content and value are in int range.
12116 (ccl_driver, Fregister_code_conversion_map):
12117 Check that Vcode_version_map_vector is a vector.
12118 (resolve_symbol_ccl_program): Check that vector header is in range.
12119 Always copy the vector, so that we can check its contents reliably
12120 now rather than having to recheck each instruction as it's being
12121 executed. Check that vector words fit in 'int'.
12122 (ccl_get_compiled_code, Fregister_ccl_program)
12123 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12124 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12125 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12126 contents are in range.
12127 (Fccl_execute_on_string): Check that status is in range.
12128 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12129 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12130 Accept and return EMACS_INT, not int, because callers can pass values
12131 out of 'int' range.
12132 (c_string_width, strwidth, lisp_string_width, chars_in_text)
12133 (multibyte_chars_in_text, parse_str_as_multibyte)

12135 (str_as_unibyte, str_to_unibyte, string_count_byte8)
12136 (string_escape_byte8, Fget_byte):
12137 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12138 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12139 avoid mishandling large integers.
12140 * character.h: Adjust decls to match defn changes elsewhere.
12141 * charset.c (load_charset_map_from_file, find_charsets_in_text)
12142 (Ffind_charset_region):
12143 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

12145 (load_charset_map_from_vector, Fdefine_charset_internal):
12146 Don't assume fixnum fits in int.
12147 (load_charset_map_from_vector, Fmap_charset_chars):
12148 Remove now-unnecessary CHECK_NATNUMs.
12149 (Fdefine_charset_internal): Check ranges here, more carefully.
12150 Don't rely on undefined behavior with signed left shift overflow.
12151 Don't assume unsigned int fits into fixnum, or that fixnum fits
12152 into unsigned int. Don't require max_code to be a valid fixnum;
12153 that's not true for gb10830 4-byte on a 32-bit host. Allow

12155 to be a character. Avoid int overflow if max_char is close

12821 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12822 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
12823 short is wide enough.
12824 (x_send_client_event): Don't assume fixnum fits in int.
12825 * xterm.c (x_x_to_emacs_modifiers):
12826 Don't assume EMACS_INT overflows nicely into int.
12827 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
12828 may come from Lisp.
12829 (handle_one_xevent): NATNUMP can eval its arg twice.
12830 (x_connection_closed):
12831 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12832 * xterm.h: Adjust decls to match defn changes elsewhere.
12833 (struct scroll_bar): Use struct vectorlike_header
12834 rather than rolling our own approximation.
12835 (SCROLL_BAR_VEC_SIZE): Remove; not used.
12837 2012-05-25 Glenn Morris <rgm@gnu.org>
12839 * lisp.mk (lisp): Update for more files being compiled now.
12841 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
12843 * lread.c: Remove `read_pure' which makes no difference.
12844 (read_pure): Remove var.
12845 (unreadpure): Remove function.
12846 (readevalloop): Don't call read_list with -1 flag.
12847 (read1, read_vector): Don't test read_pure any more.
12848 (read_list): Simplify.
12850 * fileio.c, character.h: Minor style tweaks.
12852 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
12854 * window.h (clip_changed): Remove useless declaration.
12856 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
12858 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
12859 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
12861 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
12864 This directory predates autoconf and is no longer needed nowadays.
12865 Move its few remaining bits of functionality to where they're needed.
12866 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
12867 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
12868 * m/template.h: Remove.
12869 * Makefile.in (M_FILE): Remove. All uses removed.
12870 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
12871 * lisp.h (USE_LSB_TAG):
12872 * mem-limits.h (EXCEEDS_LISP_PTR):
12873 Use VAL_MAX, not VALBITS, in #if.
12874 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
12875 (EMACS_UINT): Define unconditionally now.
12876 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
12877 (BITS_PER_EMACS_INT): New constants, replacing
12878 what used to be in config.h, but not useful in #if.
12879 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
12880 define them any more.
12881 (VAL_MAX): New macro.
12883 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
12884 BITS_PER_EMACS_INT, in #if.
12885 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
12886 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
12887 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
12888 * s/ms-w32.h (DATA_START):
12889 Move here from removed file m/intel386.h.
12890 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
12891 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
12893 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
12895 Assume C89 or later.
12896 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
12897 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
12899 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
12900 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
12901 * textprop.c, tparam.c (NULL): Remove.
12902 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
12903 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
12904 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
12905 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
12906 * xterm.c (input_signal_count): Assume volatile works.
12908 2012-05-21 Ken Brown <kbrown@cornell.edu>
12910 * xgselect.c (xg_select): Fix first argument in call to 'select'
12913 2012-05-20 Ken Brown <kbrown@cornell.edu>
12915 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
12916 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
12918 2012-05-19 Ken Brown <kbrown@cornell.edu>
12920 * xfns.c (x_in_use): Remove `static' qualifier.
12921 * xterm.h (x_in_use): Declare.
12922 * xgselect.c: Include xterm.h.
12923 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
12924 and `display_arg' (bug#9754).
12926 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
12928 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
12930 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
12931 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
12933 2012-05-18 Eli Zaretskii <eliz@gnu.org>
12935 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
12937 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
12938 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
12940 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
12941 reference to image_cache->refcount.
12942 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
12944 2012-05-17 Juri Linkov <juri@jurta.org>
12946 * search.c (Fword_search_regexp, Fword_search_backward)
12947 (Fword_search_forward, Fword_search_backward_lax)
12948 (Fword_search_forward_lax): Move functions to isearch.el
12949 (bug#10145, bug#11381).
12951 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12953 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12955 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12957 * lread.c (init_obarray): Declare Qt and Qnil as special.
12959 2012-05-14 Glenn Morris <rgm@gnu.org>
12961 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12962 Put "libexec" before "bin", for the sake of init_callproc_1.
12964 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12966 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12968 * unexaix.c: Port to more-recent AIX compilers.
12969 (report_error, report_error_1, make_hdr, copy_sym)
12970 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12971 Make arguments const char *, not char *, to avoid violations of C
12972 standard and to fix some AIX warnings reported by Gilles Pion.
12974 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12976 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12977 already have overlays loaded.
12978 (handle_single_display_spec): Before returning without displaying
12979 fringe bitmap, synchronize the bidi iterator with the main display
12980 iterator, by calling iterate_out_of_display_property.
12981 (iterate_out_of_display_property): Detect buffer iteration by
12982 testing that it->string is a Lisp string.
12983 (get_next_display_element): When the current object is exhausted,
12984 and there's something on it->stack, call set_iterator_to_next to
12985 proceed with what's on the stack, instead of returning zero.
12986 (set_iterator_to_next): If called at the end of a Lisp string,
12987 proceed to consider_string_end without incrementing string
12988 position. Don't increment display vector index past the end of
12989 the display vector. (Bug#11417)
12990 (pos_visible_p): Don't report a position visible when move_it_to
12991 stopped at the last line of window, which happens to be scanned
12992 backwards by the bidi iteration. (Bug#11464)
12994 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12996 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12997 and right-margin display specs even if the spec is invalid or we
12998 are on a TTY, and thus unable to display on the fringes.
12999 That's because the text with the property will not be displayed anyway,
13000 so we need to signal to the caller that this is a "replacing"
13001 display spec. This fixes display when the spec is invalid or we
13004 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13006 * unexaix.c (make_hdr): Fix typo in prototype.
13007 This bug broke the build on AIX. Problem reported by Gilles Pion.
13009 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13011 * keyboard.c (kbd_buffer_get_event): Read special events also in
13012 batch mode. (Bug#11415)
13014 2012-05-12 Glenn Morris <rgm@gnu.org>
13016 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13018 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13020 * lisp.mk (lisp): Add newcomment.elc.
13022 2012-05-12 Glenn Morris <rgm@gnu.org>
13024 * Makefile.in (MKDIR_P): New, set by configure.
13025 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13027 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13029 Remove unused function hourglass_started.
13030 * dispextern.h (hourglass_started):
13031 * w32fns.c (hourglass_started):
13032 * xdisp.c (hourglass_started): Remove.
13034 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13036 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13037 Update dependencies.
13039 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13041 * xgselect.c (xg_select): Put maxfds+1 into a var.
13042 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13044 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13046 2012-05-10 Dave Abrahams <dave@boostpro.com>
13048 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13049 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13051 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13053 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13054 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13055 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13056 Initialize xd_registered_buses.
13058 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13060 Untag more efficiently if USE_LSB_TAG.
13061 This is based on a proposal by YAMAMOTO Mitsuharu in
13062 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13063 For an admittedly artificial (nth 8000 longlist) benchmark on
13064 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13065 Emacs's overall text size by 1%.
13066 * lisp.h (XUNTAG): New macro.
13067 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13068 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13069 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13070 * eval.c (Fautoload):
13071 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13072 * frame.h (XFRAME): Use XUNTAG.
13074 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13075 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13076 Remove unportable assumptions about print widths of types like
13078 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13079 intptr_t when converting between pointer and integer, to avoid GCC
13080 warnings about wrong width.
13082 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13084 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13085 stack for each reader_thread, instead of defaulting to 8MB
13086 determined by the linker. This avoids failures in creating
13087 subprocesses on Windows 7, see the discussion in this thread:
13088 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13090 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13092 Fix up display of the *Minibuf-0* buffer in the mini window.
13093 * keyboard.c (read_char): Don't clear the echo area if there's no
13095 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13096 contents of *Minibuf-0*) if there's no message displayed in its stead.
13098 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13100 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13103 2012-05-06 Chong Yidong <cyd@gnu.org>
13105 * lisp.mk (lisp): Update.
13107 2012-05-05 Jim Meyering <meyering@redhat.com>
13109 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13111 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13113 * data.c (PUT_ERROR): New macro.
13114 (syms_of_data): Use it. Add new error type `user-error'.
13115 * undo.c (user_error): New function.
13116 (Fprimitive_undo): Use it.
13117 * print.c (print_error_message): Adjust print style for `user-error'.
13118 * keyboard.c (user_error): New function.
13119 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13121 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13123 Do not limit current-time-string to years 1000..9999.
13124 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13125 (Fcurrent_time_string): Support any year that is supported by the
13126 underlying localtime representation. Don't use asctime, as it
13127 has undefined behavior for years outside the range -999..9999.
13129 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13131 Fix race conditions involving setenv, gmtime, localtime, asctime.
13132 Without this fix, interrupts could mess up code that uses these
13133 nonreentrant functions, since setting TZ invalidates existing
13134 tm_zone or tzname values, and since most of these functions return
13135 pointers to static storage.
13136 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13137 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13138 Grow the critical sections to include not just invoking
13139 localtime/gmtime, but also accessing these functions' results
13140 including their tm_zone values if any, and any related TZ setting.
13141 (format_time_string): Last arg is now struct tm *, not struct tm **,
13142 so that the struct tm is saved in the critical section.
13143 All callers changed. Simplify allocation of initial buffer, partly
13144 motivated by the fact that memory allocation needs to be outside
13145 the critical section.
13147 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13149 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13150 with RESET_INTERVAL.
13152 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13153 Remove duplicated buffer name initialization.
13155 2012-05-02 Jim Meyering <jim@meyering.net>
13157 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13159 * xfns.c (x_window): Use xstrdup (Bug#11375).
13161 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13163 * xdisp.c (pos_visible_p): If already at a newline from the
13164 display string before the 'while' loop, don't walk back the glyphs
13165 from it3.glyph_row. Solves assertion violation when the display
13166 string begins with a newline (egg.el). (Bug#11367)
13168 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13170 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13173 2012-05-01 Glenn Morris <rgm@gnu.org>
13175 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13176 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13177 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13178 All were removed before 23.1.
13180 * dispnew.c: Remove HAVE_LIBNCURSES test;
13181 it is always true on relevant platforms.
13183 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13184 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13186 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13188 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13190 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13191 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13194 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13196 Do not avoid creating empty evaporating overlays (Bug#9642).
13197 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13198 That is, do not delete an evaporating overlay if it becomes
13199 empty after its bounds are adjusted to fit within its buffer.
13200 This fix caused other problems, and I'm reverting it until we get
13201 to the bottom of them.
13203 2012-04-27 Chong Yidong <cyd@gnu.org>
13205 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13207 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13209 * xdisp.c (pos_visible_p): If the window start position is beyond
13210 ZV, start the display from buffer beginning. Prevents assertion
13211 violation in init_iterator when the minibuffer window is scrolled
13212 via the scroll bar.
13214 * window.c (window_scroll_pixel_based): Likewise.
13216 2012-04-27 Chong Yidong <cyd@gnu.org>
13218 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13220 2012-04-27 Glenn Morris <rgm@gnu.org>
13222 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13223 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13225 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13227 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13228 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13230 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13232 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13233 display element, check also the underlying string or buffer
13234 character. (Bug#11341)
13236 * w32menu.c: Include w32heap.h.
13237 (add_menu_item): If the call to AppendMenuW (via
13238 unicode_append_menu) fails, disable Unicode menus only if we are
13239 running on Windows 9X/Me.
13241 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13243 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13244 (xgetint): Add missing shift for LSB tags.
13246 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13248 * keyboard.c (read_char): Don't wipe echo area for select window
13249 events: These might get delayed via `mouse-autoselect-window'
13252 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13254 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13255 manipulation of :loaded-from data.
13257 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13259 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13260 now a cons (bug#11311).

13264 Do not create empty overlays with the evaporate property (Bug#9642).
13265 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13266 if it becomes empty after its bounds are adjusted to fit within
13267 its buffer. Without this fix, in a nonempty buffer (let ((o
13268 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13269 yields an empty overlay that has the evaporate property, which is
13270 not supposed to happen.
13272 Fix minor GTK3 problems found by static checking.
13273 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

13293 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13294 (__malloc_size_t, __malloc_ptrdiff_t):
13295 Remove. All uses removed, replaced by the definiens if needed,
13296 since we can assume C89 or better now.

13385 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13387 * sysdep.c [__FreeBSD__]: Minor cleanups.
13388 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13389 Use Emacs indenting style more consistently. Avoid some casts.

13415 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13416 set the status to "failed" and ensure that sentinel is run.
13418 2012-04-20 Glenn Morris <rgm@gnu.org>
13420 * process.c (Fset_process_inherit_coding_system_flag)

13473 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13474 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13475 (NEED_MEM_INSERT): New macro.
13476 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13477 Remove one incorrect comment and fix another.

13513 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13514 * s/netbsd.h, s/sol2-6.h:
13515 Remove definition of GC_MARK_STACK, since the default now works.
13516 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

13544 2012-04-11 Daniel Colascione <dancol@dancol.org>
13546 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13547 against is gone. It's better to use vfork now so that when Cygwin
13548 gains a new, working vfork, we use it automatically (bug#10398).
13550 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

13603 * minibuf.c (Fread_variable): Callers changed.
13605 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13607 * xdisp.c (set_cursor_from_row): If the display string appears in
13608 the buffer at position that is closer to point than the position
13609 after the display string, display the cursor on the first glyph of
13610 the display string. Fixes cursor display when a 'display' text
13611 property immediately follows invisible text. (Bug#11094)
13613 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13615 composite.c: use 'double' consistently
13616 * composite.c (get_composition_id): Use 'double' consistently
13617 instead of converting 'float' to 'double' and vice versa; this is
13618 easier to understand and avoids a GCC warning.
13620 2012-04-09 Glenn Morris <rgm@gnu.org>
13622 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13623 preparation for dumping it with emacs. (Bug#4789)

13667 [!WINDOWSNT]: New macros.
13668 (init_libxml2_functions, libxml2_loaded_p): New functions.
13669 (parse_region): Call fn_xmlCheckVersion instead of using the macro

13672 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13674 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13675 Call init_libxml2_functions before calling libxml2 functions.
13676 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13678 * emacs.c: Don't include libxml/parser.h.

13686 * indent.c (Fvertical_motion): If there is a display string at
13687 point, use it.vpos to compute how many lines to backtrack after
13688 move_it_to point. (Bug#11133)
13690 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13692 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13693 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13694 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13695 macros related to unification of CJK characters. For the details,
13696 see the discussion following the message here:
13697 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13699 2012-04-04 Chong Yidong <cyd@gnu.org>
13701 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13703 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13705 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13706 instead of alloca. (Bug#11138)
13708 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13710 * w32menu.c (is_simple_dialog): Properly check lisp types.
13713 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13715 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13716 position we get to after a call to move_it_to fails the
13717 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13718 only if we wind up in a string from display property. (Bug#11063)
13720 * window.c (Fdelete_other_windows_internal): Invalidate the row
13721 and column information about mouse highlight, so that redisplay
13722 restores it after reallocating the glyph matrices. (Bug#7464)
13724 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13725 string comes from a `display' text property, use the buffer
13726 position of that property as if we actually saw that position in
13728 (move_it_by_lines): Remove the assertion that
13729 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13730 violated when there's a before-string at the beginning of a line.
13733 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13735 * xdisp.c (append_space_for_newline): If the default face was
13736 remapped, use the remapped face for the appended newline.
13737 (extend_face_to_end_of_line): Use the remapped default face for
13738 extending the face to the end of the line.
13739 (display_line): Call extend_face_to_end_of_line when the default
13740 face was remapped. (Bug#11068)
13742 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13744 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13746 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13748 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13750 2012-03-27 Glenn Morris <rgm@gnu.org>
13752 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13755 2012-03-26 Kenichi Handa <handa@m17n.org>
13757 * dispextern.h (struct glyph): Fix previous change. Change the
13758 bit length of glyphless.ch to 25 (Bug#11082).
13760 2012-03-26 Chong Yidong <cyd@gnu.org>
13762 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13763 (command_loop_1): Use it; inhibit selection update for
13764 handle-select-window too (Bug#8996).
13766 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13768 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13770 2012-03-25 Kenichi Handa <handa@m17n.org>
13772 * dispextern.h (struct glyph): Change the bit length of
13773 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13775 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13777 * s/ms-w32.h (tzname): Include time.h before redirecting to
13778 _tzname. Fixes the MSVC build. (Bug#9960)
13780 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13782 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13785 * xterm.c (XTread_socket): Only modify handling_signal if
13786 !SYNC_INPUT. (Bug#11080)
13788 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13790 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13791 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13792 when fetching a multibyte character consumes more bytes than
13793 CHAR_BYTES returns, due to unification of CJK characters in
13794 string_char. (Bug#11073)
13796 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13798 * process.c (wait_reading_process_output): Handle pty disconnect
13799 by refraining from sending oneself a SIGCHLD (bug#10933).
13801 2012-03-22 Chong Yidong <cyd@gnu.org>
13803 * dispextern.h (struct it): New member string_from_prefix_prop_p.
13805 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
13806 Mark string as coming from a prefix property.
13807 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13808 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13810 2012-03-21 Chong Yidong <cyd@gnu.org>
13812 * xfaces.c (Vface_remapping_alist): Doc fix.
13814 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13816 * w32proc.c (Fw32_set_console_codepage)
13817 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13820 2012-03-20 Chong Yidong <cyd@gnu.org>
13822 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13823 to reflect default non-nil value of redisplay-dont-pause.
13825 2012-03-19 Kenichi Handa <handa@m17n.org>
13827 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13828 it fit in a valid range (Bug#11003).
13830 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13832 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13833 that is not from display property, accept the row as a "cursor
13834 row" if one of the string's character has a non-nil `cursor'
13835 property. Fixes cursor positioning when there are newlines in
13836 overlay strings, e.g. in icomplete.el. (Bug#11035)
13838 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13840 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13842 2012-03-12 Chong Yidong <cyd@gnu.org>
13844 * eval.c (inhibit_lisp_code): Rename from
13845 inhibit_window_configuration_change_hook; move from window.c.
13847 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13848 * window.c (run_window_configuration_change_hook)
13849 (syms_of_window): Callers changed.
13851 2012-03-11 Chong Yidong <cyd@gnu.org>
13853 * keymap.c (Fkey_description): Doc fix (Bug#9700).
13855 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
13857 2012-03-10 Chong Yidong <cyd@gnu.org>
13859 * frame.c (other_visible_frames): Don't assume the selected frame
13860 is visible (Bug#10955).
13862 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13864 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13866 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13868 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13869 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13872 2012-03-03 Glenn Morris <rgm@gnu.org>
13874 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13876 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13878 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13879 position past the first glyph_row that ends at ZV. (Bug#10902)
13880 (redisplay_window, next_element_from_string): Fix typos in
13882 (redisplay_window): Pass to move_it_vertically the margin in
13883 pixels, not in screen lines.
13885 2012-03-02 Glenn Morris <rgm@gnu.org>
13887 * buffer.c (buffer-list-update-hook): Doc fix.
13889 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13891 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13892 push_it before setting up the iterator for the first overlay
13893 string, even if we have an empty string loaded.
13894 (next_overlay_string): If there's an empty string on the iterator
13895 stack, pop the stack. (Bug#10903)
13897 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13899 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13900 Suggested by Stefan Monnier in
13901 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13902 * alloc.c (widen_to_Lisp_Object): New static function.
13903 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13904 and widening them to Lisp_Objects. This would work even if
13905 USE_LSB_TAG is defined and wide integers are used, which might
13906 happen in a future version of Emacs.
13908 2012-02-25 Chong Yidong <cyd@gnu.org>
13910 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13913 * xselect.c (Fx_selection_exists_p): Doc fix.
13914 (x_clipboard_manager_save_all): Print an informative message
13915 before saving to clipboard manager.
13917 2012-02-24 Chong Yidong <cyd@gnu.org>
13919 * keyboard.c (process_special_events): Handle all X selection
13920 requests in kbd_buffer, not just the next one (Bug#8869).
13922 2012-02-23 Chong Yidong <cyd@gnu.org>
13924 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13925 call when setting menu-bar-lines and tool-bar-lines parameters.
13926 (unwind_create_frame_1): New helper function.
13928 * window.c (inhibit_window_configuration_change_hook): New var.
13929 (run_window_configuration_change_hook): Obey it.
13930 (syms_of_window): Initialize it.
13932 2012-02-22 Chong Yidong <cyd@gnu.org>
13934 * xterm.c (x_draw_image_relief): Add missing type check for
13935 Vtool_bar_button_margin (Bug#10743).
13937 2012-02-21 Chong Yidong <cyd@gnu.org>
13939 * fileio.c (Vfile_name_handler_alist): Doc fix.
13941 * buffer.c (Fget_file_buffer): Protect against invalid file
13942 handler return value.
13944 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13946 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13947 when computing $valmask.
13949 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13950 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13951 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13952 It's useless in that case, and it can cause problems on hosts
13953 that allocate halves of EMACS_INT values separately.
13954 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13955 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13956 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13957 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13958 it avoids undefined behavior on hosts where shifting right by more
13959 than the word width has undefined behavior.
13961 2012-02-19 Chong Yidong <cyd@gnu.org>
13963 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13964 (Funhandled_file_name_directory, Ffile_name_as_directory)
13965 (Fdirectory_file_name, Fexpand_file_name)
13966 (Fsubstitute_in_file_name): Protect against invalid file handler
13967 return values (Bug#10845).
13969 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13971 * .gdbinit (pitx): Fix incorrect references to fields of the
13974 2012-02-17 Chong Yidong <cyd@gnu.org>

13978 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
13980 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
13981 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
13983 2012-02-15 Chong Yidong <cyd@gnu.org>
13985 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
13986 marked as special. Also, starting docstrings with * is obsolete.
13988 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
13990 * gnutls.c (emacs_gnutls_write): Fix last change.
13992 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
13994 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
13997 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
13999 * keymap.c (Fsingle_key_description): Handle char ranges.
14001 2012-02-12 Chong Yidong <cyd@gnu.org>
14003 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14004 as that creates a dangerous corner case.
14006 * window.c (Fdelete_window_internal): Invalidate the mouse
14007 highlight (Bug#9904).
14009 2012-02-12 Glenn Morris <rgm@gnu.org>
14011 * xselect.c (Fx_own_selection_internal)
14012 (Fx_get_selection_internal, Fx_disown_selection_internal)
14013 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
14014 * nsselect.m (Fx_own_selection_internal)
14015 (Fx_disown_selection_internal, Fx_selection_exists_p)
14016 (Fx_selection_owner_p, Fx_get_selection_internal):
14017 Sync docs and argument specs with the xselect.c versions.
14019 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
14021 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
14023 2012-02-11 Eli Zaretskii <eliz@gnu.org>
14025 * w32select.c (Fx_selection_exists_p): Sync doc string and
14026 argument list with xselect.c. (Bug#10783)
14028 * w16select.c (Fx_selection_exists_p): Sync doc string and
14029 argument list with xselect.c. (Bug#10783)
14031 2012-02-10 Glenn Morris <rgm@gnu.org>
14033 * fns.c (Fsecure_hash): Doc fix.
14035 2012-02-09 Kenichi Handa <handa@m17n.org>
14037 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
14039 2012-02-07 Chong Yidong <cyd@gnu.org>
14041 * buffer.c (Fbuffer_local_variables)
14042 (buffer_lisp_local_variables): Handle unbound vars correctly;
14043 don't let Qunbound leak into Lisp.
14045 2012-02-07 Glenn Morris <rgm@gnu.org>
14047 * image.c (Fimagemagick_types): Doc fix.
14049 * image.c (imagemagick-render-type): Change it from a lisp object
14050 to an integer. Move the doc here from the lisp manual.
14051 Treat all values not equal to 0 the same.
14053 2012-02-06 Chong Yidong <cyd@gnu.org>
14055 * doc.c (store_function_docstring): Avoid applying docstring of
14056 alias to base function (Bug#2603).
14058 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
14060 * .gdbinit (pp1, pv1): Remove redundant defines.
14063 2012-02-04 Chong Yidong <cyd@gnu.org>
14065 * nsterm.m: Declare a global (Bug#10694).
14067 2012-02-04 Eli Zaretskii <eliz@gnu.org>
14069 * w32.c (get_emacs_configuration_options):
14070 Include --enable-checking, if specified, in the return value.
14072 2012-02-04 Martin Rudalics <rudalics@gmx.at>
14074 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
14075 after rounding frame sizes. (Bug#9723)
14077 2012-02-04 Eli Zaretskii <eliz@gnu.org>
14079 * keyboard.c (adjust_point_for_property): Don't position point
14080 before BEGV. (Bug#10696)
14082 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
14084 Handle overflow when computing char display width (Bug#9496).
14085 * character.c (char_width): Return EMACS_INT, not int.
14086 (char_width, c_string_width): Check for overflow when
14087 computing the width; this is possible now that individual
14088 characters can have unbounded width. Problem introduced
14089 by merge from Emacs 23 on 2012-01-19.
14091 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
14093 * dbusbind.c (Fdbus_register_method): Mention the return value
14094 :ignore in the docstring.
14096 2012-02-02 Glenn Morris <rgm@gnu.org>
14098 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
14100 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
14101 Unconditionally set to t. (Bug#10673)

14106 2012-02-02 Kenichi Handa <handa@m17n.org>
14108 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
14109 0, do not call append_composite_glyph.
14111 2012-02-02 Kenichi Handa <handa@m17n.org>
14113 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
14115 (x_produce_glyphs): If the component of a composition is a null
14116 string, set it->pixel_width to 1 to avoid zero-width glyph.
14118 2012-02-01 Eli Zaretskii <eliz@gnu.org>
14120 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
14121 first 2 arguments are identical. This makes inserting large
14122 output from a subprocess an order of magnitude faster on
14123 MS-Windows, where all sbrk'ed memory is always contiguous.
14125 2012-01-31 Glenn Morris <rgm@gnu.org>
14127 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

14163 2012-01-21 Chong Yidong <cyd@gnu.org>
14165 * floatfns.c (Fcopysign): Make the second argument non-optional,
14166 since nil is not allowed anyway.
14168 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
14170 * process.c (read_process_output): Use p instead of XPROCESS (proc).
14171 (send_process): Likewise.
14173 2012-01-19 Martin Rudalics <rudalics@gmx.at>
14175 * window.c (save_window_save, Fcurrent_window_configuration)

14653 * xdisp.c (redisplay_window): If cursor row is not fully visible
14654 after recentering, and scroll-conservatively is set to a large
14655 number, scroll window by a few more lines to make the cursor fully
14656 visible and out of scroll-margin. (Bug#10105)
14657 (start_display): Don't move to the next line if the display should
14658 start at a newline that is part of a display vector or an overlay
14659 string. (Bug#10119)

14738 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
14739 Otherwise, valgrind does not work on some platforms.
14740 Problem reported by Andreas Schwab in
14741 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
14742 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14743 is set, removing the need for VIRT_ADDRESS_VARIES.
14744 (PURE_P): Use a more-efficient implementation that needs just one
14745 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
14746 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
14747 to 4 (xorl, subq, cmpq, setbe).
14748 * alloc.c (pure): Always extern now, since that's the
14749 VIRT_ADDR_VARIES behavior.
14750 (PURE_POINTER_P): Use a single comparison, not two, for
14751 consistency with the new puresize.h.
14752 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14753 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14759 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14760 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14761 behave as if the cursor position were at the window margin.
14763 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14764 and the cursor position is out of bounds, behave as if the cursor
14765 position were at the window margin. (Bug#10075)
14767 2011-11-18 Chong Yidong <cyd@gnu.org>
14769 * window.c (Fwindow_combination_limit): Make first argument

14790 * xdisp.c (row_hash): New function, body extracted from
14791 compute_line_metrics.
14792 (compute_line_metrics): Call row_hash, instead of computing the
14795 * dispnew.c (verify_row_hash): Call row_hash for computing the
14796 hash code of a row, instead of duplicating code from xdisp.c.
14798 * dispextern.h (row_hash): Add prototype.
14800 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

14836 2011-11-14 Eli Zaretskii <eliz@gnu.org>
14838 * xdisp.c (display_line): Move the call to
14839 highlight_trailing_whitespace before the call to
14840 compute_line_metrics, since the latter needs to see the final
14841 faces of all the glyphs to compute ROW's hash value.
14842 Fixes assertion violations in row_equal_p. (Bug#10035)
14844 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
14846 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
14847 just return (bug#10044).
14849 2011-11-12 Eli Zaretskii <eliz@gnu.org>
14851 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14852 with user-defined heap size. Bump the default size of the temacs
14853 heap to 27MB, to avoid memory warning when running temacs.

14856 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14857 current_matrix and desired_matrix. (Bug#9990)
14858 (verify_row_hash) [XASSERTS]: New function.

14905 Avoid some portability problems by eschewing 'extern inline' functions.
14906 The trivial performance wins aren't worth the portability hassles; see
14907 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14909 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14912 by removing the "extern"s.
14913 * intervals.c (adjust_intervals_for_insertion)
14914 (adjust_intervals_for_deletion): Undo previous change,
14915 making these static again.
14916 (offset_intervals, temp_set_point_both, temp_set_point)
14917 (copy_intervals_to_string): No longer inline.
14918 * xdisp.c (window_text_bottom_y, window_box_width)

14975 * xmenu.c (cleanup_widget_value_tree): New function.
14976 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

14983 (window_box_width, window_box_left, window_box_left_offset)
14984 (window_box_right, window_box_right_offset): Declare extern.
14985 Otherwise, these inline functions do not conform to C99 and
14986 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14987 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14988 * intervals.c (adjust_intervals_for_insertion)
14989 (adjust_intervals_for_deletion): Now extern, because otherwise the

14991 (static_offset_intervals): Remove.
14992 (offset_intervals): Rewrite using the old contents of
14993 static_offset_intervals. The old version didn't conform to C99
14994 because an extern inline function contained a reference to an
14995 identifier with static linkage.

15048 (unwind_create_frame): New function (Bug#9943).
15049 (Fx_create_frame): Restructure code to be more similar to the one in
15050 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

15056 (x_destroy_window): Move code to x_free_frame_resources.
15058 * xfns.c (unwind_create_frame): Fix comment.

15061 official. Move initialization of image_cache_refcount and
15062 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

15107 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
15108 label is not null (Bug#9951).
15109 (xg_tool_item_stale_p): Handle the fact that wimage and/or wlbl
15112 2011-11-04 Eli Zaretskii <eliz@gnu.org>
15114 * window.c (Fwindow_body_size): Mention in the doc string that the
15115 return value is in frame's canonical units. (Bug#9949)
15117 2011-11-03 Eli Zaretskii <eliz@gnu.org>
15119 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
15121 * w32fns.c (unwind_create_frame): If needed, free the glyph
15122 matrices of the partially constructed frame. (Bug#9943)
15123 * xfns.c (unwind_create_frame): Likewise.
15125 2011-11-01 Eli Zaretskii <eliz@gnu.org>
15127 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
15128 Don't stop backward scan on the continuation glyph, even though
15129 its CHARPOS is positive.
15130 (mouse_face_from_buffer_pos, note_mouse_highlight):
15131 Rename cover_string to disp_string.
15133 2011-11-01 Martin Rudalics <rudalics@gmx.at>
15135 * window.c (temp_output_buffer_show): Don't use
15136 Vtemp_buffer_show_specifiers.
15137 (Vtemp_buffer_show_specifiers): Remove unused variable.
15139 2011-10-30 Eli Zaretskii <eliz@gnu.org>
15141 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
15142 past the beginning of the current glyph matrix.
15144 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
15146 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
15147 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
15148 HAVE_GTK3 (Bug#9869).
15150 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
15151 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
15153 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
15155 * xterm.c: Declare x_handle_net_wm_state to return int.
15156 (handle_one_xevent): Check if we are iconified but don't have
15157 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
15158 (get_current_wm_state): Return non-zero if not hidden,
15159 check for _NET_WM_STATE_HIDDEN (Bug#9893).

15161 (x_handle_net_wm_state): Return what get_current_wm_state returns.
15162 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
15164 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
15166 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
15167 so that this new function doesn't get optimized away by a
15168 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
15170 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
15172 * frame.h (MOUSE_HL_INFO): Remove excess parens.
15174 2011-10-29 Eli Zaretskii <eliz@gnu.org>
15176 Fix the `xbytecode' command.
15177 * .gdbinit (xprintbytestr): New command.
15178 (xwhichsymbols): Rename from `which'; all callers changed.
15179 (xbytecode): Print the byte-code string as well.
15181 2011-10-29 Kim Storm <storm@cua.dk>
15183 * alloc.c (which_symbols): New function.
15185 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
15187 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
15190 2011-10-29 Glenn Morris <rgm@gnu.org>
15192 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
15193 Not clear what it was for, and it causes various bugs. (Bug#9839)
15195 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15197 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
15198 possible random value that matches one of those tested as
15199 condition to clear the mouse face.
15201 2011-10-28 Chong Yidong <cyd@gnu.org>
15203 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
15205 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
15207 * window.c (make_window): Initialize phys_cursor_on_p.
15209 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
15211 * lisp.h (struct Lisp_Symbol): Update comments.
15213 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
15215 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
15217 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15219 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
15220 <oslsachem@gmail.com> for helping to debug this.
15222 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
15223 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
15224 (g_b_init_get_glyph_outline_w): New static variables.
15225 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
15226 (GetGlyphOutlineW_Proc): New typedefs.
15227 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
15228 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
15230 (w32font_open_internal, compute_metrics):
15231 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15232 instead of calling the "wide" APIs directly.
15234 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
15236 * w32.h (syms_of_w32font): Add prototype.
15238 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15240 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
15241 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
15242 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
15243 (Fmove_to_window_line): Doc fix.
15245 2011-10-27 Chong Yidong <cyd@gnu.org>
15247 * process.c (make_process): Set gnutls_state to NULL.
15249 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15250 non-NULL, regardless of GNUTLS_INITSTAGE.
15251 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
15252 an error. Set process slots as soon as we allocate them.
15254 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
15256 2011-10-27 Chong Yidong <cyd@gnu.org>
15258 * gnutls.c (emacs_gnutls_deinit): New function.
15259 Deallocate credentials structures as well as calling gnutls_deinit.
15260 (Fgnutls_deinit, Fgnutls_boot): Use it.
15262 * process.c (make_process): Initialize GnuTLS credentials to NULL.
15263 (deactivate_process): Call emacs_gnutls_deinit.
15265 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15267 * image.c (x_create_x_image_and_pixmap):
15268 * w32.c (sys_rename, w32_delayed_load):
15269 * w32font.c (fill_in_logfont):
15270 * w32reg.c (x_get_string_resource): Silence compiler warnings.
15272 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
15274 * w32fns.c (w32_default_color_map): New function,
15275 extracted from Fw32_default_color_map.
15276 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
15278 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
15280 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
15282 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
15284 * keyboard.c (test_undefined): New function (bug#9751).
15285 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
15287 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
15289 * sysdep.c (init_sys_modes): Fix the check for the controlling
15290 terminal (Bug#6649).
15292 2011-10-20 Eli Zaretskii <eliz@gnu.org>
15294 * dispextern.h (struct bidi_it): New member next_en_type.
15296 * bidi.c (bidi_line_init): Initialize the next_en_type member.
15297 (bidi_resolve_explicit_1): When next_en_pos is valid for the
15298 current character, check also for next_en_type being WEAK_EN.
15299 (bidi_resolve_weak): Don't enter the expensive loop if the current
15300 position is before next_en_pos. Record the bidi type of the first
15301 non-ET, non-BN character we find, in addition to its position.
15302 (bidi_level_of_next_char): Invalidate next_en_type when
15303 next_en_pos is over-stepped.
15305 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15307 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15308 * editfns.c: Rewrite current-time-zone so that it invokes
15309 the equivalent of (format-time-string "%Z") to get the time zone name.
15310 This fixes a bug when the time zone name contains characters that
15311 need converting from the system time locale to Emacs internal format.
15312 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15313 that patch fixed format-time-string to do the conversion, but
15314 I forgot to fix current-time-zone.
15315 (format_time_string): New function, containing most of
15316 what Fformat_time_string used to contain.
15317 (Fformat_time_string): Rewrite in terms of format_time_string.
15318 This doesn't change this function's behavior.
15319 (current-time-zone): Rewrite to use format_time_string.
15320 This fixes the bug reported by Michael Schierl in
15321 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15322 Jason Rumney's 2007-06-07 change worked around this bug, but
15324 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15326 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15328 * xdisp.c (start_display): If the character at POS is displayed
15329 via a display vector, reset IT->current.dpvec_index to zero.
15330 (try_window_reusing_current_matrix): If a line ends in a display
15331 vector or the next line starts in a display vector, continue
15332 redrawing the window even though the character position of
15333 start_row was reached.
15336 2011-10-18 Chong Yidong <cyd@gnu.org>
15338 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15339 with nobreak-char-display too.
15341 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15343 Fix part 3 of bug#9771.
15344 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15345 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15346 non-neutral characters if the current character is a paragraph
15347 separator (a.k.a. Newline). This avoids running the same
15348 expensive loop twice, once when we consume the preceding newline
15349 and the other time when the line actually needs to be displayed.
15350 Avoid the loop when we see neutrals on the base embedding level
15351 following a character whose directionality is the same as the
15352 paragraph's. This avoids running the expensive loop when a line
15353 ends in a long sequence of neutrals, like control characters.
15354 Add assertion against STRONG_AL type. Slightly rearrange code
15355 that determines the type of a neutral given the first non-neutral
15357 (bidi_level_of_next_char): Set next_en_pos to zero when
15358 invalidating its info.
15360 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15362 * xdisp.c (push_display_prop): Determine whether to record string
15363 or buffer position by IT->string, not by IT->method. Allow
15364 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15365 (move_it_vertically_backward): Don't look for character position
15366 immediately after the newline when in a continuation line.
15369 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15371 * window.c (coordinates_in_window): Rewrite and delabelize
15372 vertical border check. (Bug#5357) (Bug#9618)
15374 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15376 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15377 errors in XSetWindowBorder (bug#9310).
15379 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15381 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15382 avoid crash when xmalloc overrun checking is enabled.
15384 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15386 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15387 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15388 cursor motion with <left> and <right> arrow keys.
15390 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15391 some callers set that themselves.
15393 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15395 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15396 display string and the previous row comes from the same string and
15397 is empty. (Bug#9739) (Bug#9738)
15399 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15401 * doc.c (get_doc_string): Encode file name (bug#9735).
15403 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15405 * bidi.c (bidi_level_of_next_char):
15406 * xdisp.c (get_visually_first_element): Remove old incorrect
15407 comments regarding the Unicode Line Separator character.
15409 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15411 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15413 * alloc.c (Fgc_status): Do not access beyond zombies array
15414 boundary if nzombies > MAX_ZOMBIES.
15415 * alloc.c (dump_zombies): Add missing format specifier.
15417 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15419 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15420 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15422 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15423 Some packages use them to denote characters with modifiers.
15425 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15427 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15428 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15429 matching a pp-number. Rename parameter var to var1.
15431 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15433 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15435 2011-10-08 Glenn Morris <rgm@gnu.org>
15437 * callint.c (Fcall_interactively): Give a more explicit error for the
15438 'c' case with a non-character input. (Bug#8479)
15440 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15442 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15444 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15445 lines that are hscrolled on the left.
15447 * dispnew.c (buffer_posn_from_coords): Account for a possible
15448 presence of header-line. (Bug#4426)
15450 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15452 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15453 Don't advertise functionality which we discourage or doesn't work.
15455 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15457 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15458 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15459 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15460 this makes Emacs dump core during garbage collection on rare
15461 occasions. sizeof is obviously inferior to offsetof here, so
15462 stick with offsetof.
15463 (GC_POINTER_ALIGNMENT): New macro.
15464 (mark_memory): Omit 3rd (offset) arg; caller changed.
15465 Don't assume EMACS_INT alignment is the same as pointer alignment.
15467 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15469 * keyboard.c (read_key_sequence_remapped): New var.
15470 (read_key_sequence): Compute remapping in the right buffer.
15471 (command_loop_1): Use read_key_sequence's remapping directly.
15473 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15475 * dired.c (file_name_completion): Don't expand file name.
15476 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15477 before checking file name handler.
15479 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15480 they've been requested explicitly (bug#9591).
15482 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15484 * keymap.c (Fsingle_key_description): Use make_specified_string
15485 instead of build_string to build string from push_key_description.
15488 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15490 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15491 This fixes a Y2038 bug on 64-bit hosts.
15492 * buffer.c (reset_buffer):
15493 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15494 (Fclear_buffer_auto_save_failure):
15495 Use 0, not -1, to represent an unset failure time, since time_t
15496 might not be signed.
15498 Remove dependency on glibc malloc internals.
15499 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15500 Move back here from lisp.h, but with their new implementations.
15501 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15502 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15503 * charset.c (charset_table_init): New static var.
15504 (syms_of_charset): Use it instead of xmalloc. This removes a
15505 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15506 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15507 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15508 Move back to alloc.c.
15509 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15510 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15512 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15514 * nsterm.m (windowDidResize): Call x_set_window_size only when
15515 ns_in_resize is true. Otherwise set pixelwidth/height and
15516 call change_frame_size (Bug#9628).
15518 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15520 Port --enable-checking=all to Fedora 14 x86-64.
15521 * charset.c (syms_of_charset): Also account for glibc malloc's
15522 internal overhead when calculating the initial malloc maximum.
15524 Port --enable-checking=all to Fedora 14 x86.
15525 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15527 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15528 (overrun_check_realloc, overrun_check_free):
15529 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15530 That way, xmalloc returns a properly-aligned pointer even if
15531 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15532 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15533 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15534 into account when calculating the initial malloc maximum.
15535 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15536 Move here from alloc.c, so that charset.c can use it too.
15537 Properly align; the old code wasn't right for common 32-bit hosts
15538 when configured with --enable-checking=all.
15539 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15540 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15542 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15544 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15547 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15549 * xdisp.c (compute_display_string_end): If there's no display
15550 string at CHARPOS, return -1.
15552 * bidi.c (bidi_fetch_char): When compute_display_string_end
15553 returns a negative value, treat the character as a normal
15554 character not covered by a display string. (Bug#9624)
15556 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15558 * lread.c (Fread_from_string): Fix typo in docstring.
15560 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15562 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15563 newline, reseat the iterator instead of bidi-iterating there one
15564 character at a time. (Bug#9610)
15565 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15566 TO_CHARPOS if the bidi iterator is at base embedding level.
15568 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15570 * lread.c (readevalloop): Use correct code for NBSP.
15571 (read1): Likewise. (Bug#9608)
15573 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15575 * dbusbind.c (Fdbus_register_signal): When service is not

15578 2011-09-25 Glenn Morris <rgm@gnu.org>
15580 * buffer.c (truncate-lines): Doc fix.
15582 2011-09-24 Chong Yidong <cyd@stupidchicken.com>

15600 Default value is now t. Doc fix.
15602 * indent.c (Fvertical_motion): Compute and apply the overshoot
15603 logic when moving up, not only when moving down. Fix the
15604 confusing name and values of the it_overshoot_expected variable;
15605 logic changes accordingly. (Bug#9254) (Bug#9549)
15607 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15608 CHARPOS is covered by a display string which includes newlines.
15609 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15610 is covered by a display string with embedded newlines.
15612 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15614 * dbusbind.c (Fdbus_register_signal): Add match rule to
15615 Vdbus_registered_objects_table. (Bug#9581)
15616 (Fdbus_register_method, Vdbus_registered_objects_table):
15619 2011-09-24 Jim Meyering <meyering@redhat.com>
15621 do not ignore write error for any output size
15622 The previous change was incomplete.
15623 While it makes emacs --batch detect the vast majority of stdout
15624 write failures, errors were still ignored whenever the output size is
15625 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15626 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15627 && echo FAIL: ignored write error
15628 FAIL: ignored write error
15629 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15630 && echo FAIL: ignored write error
15631 FAIL: ignored write error
15632 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15634 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15636 * emacs.c (Fkill_emacs): In noninteractive mode exit
15637 non-successfully if a write error occurred on stdout. (Bug#9574)
15639 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15641 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15644 * dispextern.h (struct it): Update the comment documenting what
15647 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15649 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15650 a display string, extend search for cursor position to end of row.
15651 (find_row_edges): If the row ends in a newline from a display
15652 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15653 Handle the case of a display string with multiple newlines.
15654 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15655 non-empty line. Fixes confusing cursor motion with arrow keys at
15656 the beginning of a line that starts with whitespace.
15658 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15660 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15663 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15665 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15666 boolean (Bug#9154).
15668 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15670 * xdisp.c (display_line): Record maximum and minimum buffer
15671 positions even if no glyphs were produced (e.g., by a zero-width
15672 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15673 buffer positions that will be removed from the glyph row because
15675 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15676 column is beyond frame width: don't subtract 1 "pixel" when
15677 computing width of the stretch.
15678 (reseat_at_next_visible_line_start): Undo the change made on
15679 2011-09-17 that saved paragraph information and restored it after
15680 the call to `reseat'. (Bug#9545)
15682 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15684 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15685 and turn window cursor on if cleared (Bug#9415).
15687 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15689 * search.c (boyer_moore): Take unibyte characters from pattern
15690 literally. (Bug#9458)

15707 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15709 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15711 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15713 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15714 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15716 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15718 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15719 about the current paragraph and restore it after the call to reseat.
15721 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15722 (bidi_find_paragraph_start): Search back for paragraph beginning
15723 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15724 (bidi_move_to_visually_next): Only trigger paragraph-related
15725 computations when the last character is a newline or at EOB, not
15726 just any NEUTRAL_B. (Bug#9470)
15728 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15729 truncated lines if point is covered by a display string. (Bug#9524)
15731 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15733 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15734 (cons_to_x_long): New function.
15735 (lisp_data_to_selection_data): Use it. Correct the test for
15736 short-versus-long data; it was negated. Break out of vector
15737 loop, for efficiency, when a long datum is discovered.
15739 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15741 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15743 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15745 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15746 GCC PR/17406) by declaring this function with external scope.
15748 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15750 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15751 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15753 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15755 * editfns.c (Fformat): Correctly handle text properties on "%%".

15765 of TAB characters in a composition.
15767 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15769 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15770 This occurs when processing a multibyte format.
15771 Problem reported by Wolfgang Jenker.
15773 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15775 * xdisp.c (try_cursor_movement): Only check for exact match if
15776 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15778 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15780 Remove unused external symbols.
15781 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15782 * xdisp.c (calc_pixel_width_or_height): Now static.
15783 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15784 * indent.c (check_display_width):
15785 * w32term.c: Fix comment to match code.
15786 * xterm.c, xterm.h (x_catching_errors): Remove.
15788 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15790 * xselect.c: Use signed conversions more consistently (Bug#9498).
15791 (selection_data_to_lisp_data): Assume incoming selection data are
15792 signed integers, not unsigned. This is to be consistent with
15793 outgoing selection data, which was modified to use signed integers
15794 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15795 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15796 expects long, not unsigned long.
15798 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15800 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15801 computation of loop end. Reported by Johan Bockgård
15804 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15806 * frame.c (Fother_visible_frames_p): Function deleted.
15808 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15810 * indent.c (compute_motion): Process display vector front to back
15811 rather than the other way around. (Bug#2496)
15813 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15815 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15817 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15819 * minibuf.c (Fread_from_minibuffer): Doc fix.
15821 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15823 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15824 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15826 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15828 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15829 value for non-existent files.
15831 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15833 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15834 set its "size" to -1. This will set the modtime_size field of
15835 the corresponding buffer to -1, which is what
15836 verify-visited-file-modtime expects for files that do not exist.
15839 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15841 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15843 * lisp.h: ... from here. push_key_description is no longer
15844 defined in keyboard.c, so its declaration should not be in
15845 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15846 logically belongs with push_key_description.
15848 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15850 * buffer.h: Include <sys/types.h> instead of <time.h>.
15851 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15852 Problem reported by Herbert J. Skuhra.
15854 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15856 * xml.c (parse_region): Make the parsing work for
15857 non-comment-starting XML files again (bug#9144).
15859 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15861 * image.c (gif_load): Fix calculation of bottom and right corner.
15864 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15866 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15867 redisplay in small windows.
15869 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15871 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15873 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15875 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15876 Operate on live windows only.
15878 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15880 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15882 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15884 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15885 only under bidi iteration.
15887 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15889 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15891 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15893 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15894 Without this fix, the command to link temacs failed due to an
15895 undefined symbol __builtin_isnan. This is because
15896 /usr/include/iso/math_c99.h #defines isnan(x) to
15897 __builtin_isnan(x), but the bundled gcc, which identifies itself
15898 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15900 * floatfns.c (isnan): #undef, and then #define to a clone of
15902 (Fisnan): Always define, since it's always available now.
15903 (syms_of_floatfns): Always define isnan at the Lisp level.
15905 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15907 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15909 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15911 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15912 The previous code assumed that file offsets (off_t values) fit in
15913 EMACS_INT variables, which is not true on typical 32-bit hosts.
15914 The code messed up by falsely reporting buffer overflow in cases
15915 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15916 when "big" contains more than 2**29 bytes, even though this
15917 inserts just one byte and does not overflow the buffer.
15918 (Finsert_file_contents): Store file offsets as off_t
15919 values, not as EMACS_INT values. Check for overflow when
15920 converting between EMACS_INT and off_t. When checking for
15921 buffer overflow or for overlap, take the offsets into account.
15922 Don't use EMACS_INT for small values where int suffices.
15923 When checking for overlap, fix a typo: ZV was used where
15924 ZV_BYTE was intended.
15925 (Fwrite_region): Don't assume off_t fits into 'long'.
15926 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15928 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15930 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15932 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15934 sprintf-related integer and memory overflow issues (Bug#9412).
15936 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15937 (esprintf, exprintf, evxprintf): New functions.
15938 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15939 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15940 (modify_event_symbol): Do not assume that the length of
15941 name_alist_or_stem is safe to alloca and fits in int.
15942 (Fexecute_extended_command): Likewise for function name and binding.
15943 (Frecursion_depth): Wrap around reliably on integer overflow.
15944 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15945 since some callers pass EMACS_INT values.
15946 (Fsingle_key_description): Don't crash if symbol name contains more
15947 than MAX_ALLOCA bytes.
15948 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15949 (get_minibuffer): Arg is now EMACS_INT, not int.
15950 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15951 (esprintf, exprintf, evxprintf): New decls.
15952 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15954 * dbusbind.c (signature_cat): New function.
15955 (xd_signature, Fdbus_register_signal):
15956 Do not overrun buffer; instead, report string overflow.
15958 * dispnew.c (add_window_display_history): Don't overrun buffer.
15959 Truncate instead; this is OK since it's just a log.
15961 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15962 even if the time zone offset is outlandishly large.
15963 Don't mishandle offset == INT_MIN.
15965 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15966 when creating daemon; the previous buffer-overflow check was incorrect.
15968 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15969 which has the guts of the old verror function.
15971 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15972 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15974 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15975 (font_unparse_xlfd): Don't blindly alloca long strings.
15976 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15977 fits in int, when using sprintf. Use single snprintf to count
15978 length of string rather than counting it via multiple sprintfs;
15979 that's simpler and more reliable.
15980 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15981 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15982 sprintf, in case result does not fit in int.
15984 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15985 (fontset_from_font): Print it.
15987 * frame.c (tty_frame_count): Now printmax_t, not int.
15988 (make_terminal_frame, set_term_frame_name): Print it.
15989 (x_report_frame_params): In X, window IDs are unsigned long,
15990 not signed long, so print them as unsigned.
15991 (validate_x_resource_name): Check for implausibly long names,
15992 and don't assume name length fits in 'int'.
15993 (x_get_resource_string): Don't blindly alloca invocation name;
15994 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15997 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15998 (xg_check_special_colors, xg_set_geometry):
15999 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16001 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16002 Use esprintf, not sprintf, in case result does not fit in int.
16004 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16005 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16006 it as a large positive number.
16007 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16008 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16010 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16011 in case result does not fit in int.
16013 * print.c (float_to_string): Detect width overflow more reliably.
16014 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16015 buffer overrun. Don't assume list length fits in 'int'. Treat
16016 print length of 0 as 0, not as infinity; to be consistent with other
16017 uses of print length in this function. Don't overflow print length
16018 index. Don't assume hash table size fits in 'long', or that
16019 vectorlike size fits in 'unsigned long'.
16021 * process.c (make_process): Use printmax_t, not int, to format
16022 process-name gensyms.
16024 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16026 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16027 to avoid potential buffer overrun.
16029 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16030 if X resource line is longer than 512 bytes.
16032 * xfns.c (x_window): Make sprintf buffer a bit bigger
16033 to avoid potential buffer overrun.
16035 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16037 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16039 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16041 Integer overflow fixes for scrolling, etc.
16042 Without these, Emacs silently mishandles large integers sometimes.
16043 For example, "C-u 4294967297 M-x recenter" was treated as if
16044 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16046 * xdisp.c (try_window_id): Check Emacs fixnum range before
16047 converting to 'int'.
16049 * window.c (window_scroll_line_based, Frecenter):
16050 Check that an Emacs fixnum is in range before assigning it to 'int'.
16051 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16052 values converted from Emacs fixnums.
16053 (Frecenter): Don't wrap around a line count if it is out of 'int'
16054 range; instead, treat it as an extreme value.
16055 (Fset_window_configuration, compare_window_configurations):
16056 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16058 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16059 that can exceed INT_MAX. Check that EMACS_INT value is in range
16060 before assigning it to the (possibly-narrower) index.
16061 (match_limit): Don't assume that a fixnum can fit in 'int'.
16063 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16066 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16067 (Fvertical_motion): Don't wrap around LINES values that don't fit
16068 in 'int'. Instead, treat them as extreme values. This is good
16069 enough for windows, which can't have more than INT_MAX lines anyway.
16071 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16073 * Require libxml/parser.h to avoid compilation warning.
16075 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16077 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16078 since this reportedly can destroy thread storage.
16080 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16082 * syntax.c (find_defun_start): Update all cache variables if
16083 exiting early (Bug#9401).
16085 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16087 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16089 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16090 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16091 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16093 * term.c (tty_append_glyph): New function.
16094 (produce_stretch_glyph): Static function and its prototype deleted.
16096 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16099 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16101 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16102 when checking :margin (Bug#9390).
16103 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16104 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16105 so that the name doesn't mislead. All uses changed.
16107 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16109 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16112 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16114 * xdisp.c (move_it_to): Don't bail out early when reaching
16115 position beyond to_charpos, if we are scanning backwards.
16116 (move_it_vertically_backward): When DY == 0, make sure we get to
16117 the first character in the line after the newline.
16119 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16121 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16122 (ccl_driver): Do not generate an out-of-range pointer.
16123 (Fccl_execute_on_string): Remove unnecessary check for
16124 integer overflow, noted by Stefan Monnier in
16125 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16126 Remove a FIXME that didn't need fixing.
16127 Simplify the newly-introduced buffer reallocation code.
16129 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16131 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16133 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16135 Integer and memory overflow issues (Bug#9196).
16137 * doc.c (get_doc_string): Rework so that
16138 get_doc_string_buffer_size is the actual buffer size, rather than
16139 being 1 less than the actual buffer size; this makes xpalloc more
16142 * image.c (x_allocate_bitmap_record, cache_image):
16143 * xselect.c (Fx_register_dnd_atom):
16144 Simplify previous changes by using xpalloc.
16146 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16147 since either will do and ptrdiff_t is convenient with xpalloc.
16149 * charset.c (charset_table_size)
16150 (struct charset_sort_data.priority): Now ptrdiff_t.
16151 (charset_compare): Don't overflow if priorities differ greatly.
16152 (Fsort_charsets): Don't assume list length fits in int.
16153 Check for size-calculation overflow when allocating sort data.
16154 (syms_of_charset): Allocate an initial charset table that is
16155 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16157 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16159 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16160 The actual value is always <= INT_MAX, and leaving it unsigned made
16161 overflow checking harder.
16163 * dispextern.h (struct glyph_matrix.rows_allocated)
16164 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16165 with xpalloc. The values are still always <= INT_MAX.
16167 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16169 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16170 (SAFE_NALLOCA): New macro.
16172 * region-cache.c (struct boundary.pos, find_cache_boundary)
16173 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16174 (set_cache_region, invalidate_region_cache)
16175 (revalidate_region_cache, know_region_cache, region_cache_forward)
16176 (region_cache_backward, pp_cache):
16177 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16178 so that ptrdiff_t * can be passed to xpalloc.
16179 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16180 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16181 (pp_cache): Don't assume cache_len fits in int.
16182 * region-cache.h: Adjust extern decls to match.
16184 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16185 EMACS_INT, since either will do, for xpalloc.
16187 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16188 (xnmalloc, xnrealloc, xpalloc): New functions.
16190 * bidi.c (bidi_shelve_header_size): New constant.
16191 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16192 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16194 * bidi.c (bidi_cache_shrink):
16195 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16197 Don't update size of array until after memory allocation succeeds,
16198 because xmalloc/xrealloc may not return.
16199 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16200 now that we have proper integer overflow checking.
16201 (record_overlay_string, overlay_strings): Catch overflows when
16202 calculating size of overlay_str_buf.
16204 * callproc.c (Fcall_process): Check for size overflow when
16205 calculating size of args2.
16206 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16207 Normally we prefer signed values, but sticking with ptrdiff_t would
16208 require adding more-complicated checks.
16210 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16211 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16212 Redo buffer-overflow calculations to avoid integer overflow.
16213 Add a FIXME comment where memory seems to be over-allocated.
16215 * character.c (Fstring): Check for size-calculation overflow.
16217 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16218 unnecessary integer overflow. Check for size overflow.
16219 (encode_coding_object): Don't update size until xmalloc succeeds.
16221 * composite.c (get_composition_id): Check for overflow in glyph
16222 length calculations.
16224 Integer and memory overflow fixes for display code.
16225 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16226 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16227 (scrolling_window): Check for overflow in size calculations.
16228 (line_draw_cost, realloc_glyph_pool, add_row_entry):
16229 Don't assume glyph table len fits in int.

16231 (row_table_size): Now ptrdiff_t, not int.
16232 (scrolling_window): Avoid overflow in size calculations.
16233 Don't update size until allocation succeeds.
16234 * fns.c (concat): Check for overflow in size calculations.
16235 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16236 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

16239 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16240 (get_doc_string): Check for size calculation overflow.
16241 Don't update size until allocation succeeds.
16242 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16243 EMACS_INT, where ptrdiff_t will do.
16244 (Fsubstitute_command_keys): Check for string overflow.
16246 * editfns.c (set_time_zone_rule): Don't assume environment length
16248 (message_length): Now ptrdiff_t, not int.
16249 (Fmessage_box): Don't update size until allocation succeeds.
16250 Don't assume message length fits in int.
16251 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16253 * emacs.c (main): Do not reallocate argv, since there is a null at
16254 the end that can be overwritten, and this way there's no need to
16255 worry about size-calculation overflow.
16256 (sort_args): Check for size-calculation overflow.
16258 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16260 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16262 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16263 (x_set_scroll_bar_width, x_figure_window_size):
16264 Check for integer overflow.
16265 (x_set_alpha): Do not assume XINT fits in int.
16267 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16268 This is for the members text_lines, text_cols, total_lines, total_cols,
16269 where the system imposes an 'int' limit.
16271 * fringe.c (Fdefine_fringe_bitmap):
16272 Don't update size until alloc works.
16274 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16275 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16277 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16278 Check for size-calculation overflow.
16279 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16280 do, as we prefer signed integers.
16281 (id_to_widget.max_size, id_to_widget.used)
16282 (xg_store_widget_in_map, xg_remove_widget_from_map)
16283 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16284 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16285 Use and return ptrdiff_t, not int.
16286 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16287 * gtkutil.h: Change prototypes to match the above.
16289 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16290 are duplicate now that they've been promoted to lisp.h.
16291 (x_allocate_bitmap_record, x_alloc_image_color)
16292 (make_image_cache, cache_image, xpm_load):
16293 Don't update size until alloc is done.
16294 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
16296 Check for size calculation overflow.
16297 (ct_colors_allocated_max): New constant.
16298 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
16301 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
16302 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
16303 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
16304 Use ptrdiff_t, not int, to count maps.
16305 (read_char_minibuf_menu_prompt): Check for overflow in size
16306 calculations. Don't update size until allocation succeeds.
16307 Redo calculations to avoid overflow.
16308 * keyboard.h: Change prototypes to match the above.
16310 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
16312 (current_minor_maps): Check for size calculation overflow.
16313 * keymap.h: Change prototypes to match the above.
16315 * lread.c (read1, init_obarray): Don't update size until alloc done.
16317 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
16318 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
16320 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
16321 Now ptrdiff_t, not int.
16322 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

16334 (Fset_match_data): Don't assume list lengths fit in 'int'.
16336 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16337 for command line length. Do not attempt to address one before the
16338 beginning of an array, as that's not portable.
16340 * term.c (max_frame_lines): Remove; unused.
16341 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
16343 (encode_terminal_code, calculate_costs): Check for size
16344 calculation overflow.

16347 done. Redo calculations to avoid overflow.
16348 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
16350 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
16351 subtracting pointers.
16352 (gobble_line): Check for overflow more carefully. Don't update size
16355 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

16366 Use ptrdiff_t, not int, for sizes.
16367 (Finternal_make_lisp_face, cache_face):
16368 Check for size calculation overflow.
16369 (cache_face): Treat size calculation overflows as if they were
16370 memory exhaustion (the usual treatment), rather than aborting.
16372 * xfns.c (x_encode_text, x_set_name_internal)
16373 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16374 sizes, since they can exceed INT_MAX in size. Check for size
16375 calculation overflow.
16377 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16378 (xg_select): Check for size calculation overflow.
16379 Don't update size until alloc done.
16381 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16382 as sprintf is limited to int lengths.
16384 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16385 (X_LONG_MIN): New macros.
16386 Use them to make the following changes clearer.
16387 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16388 This change doesn't affect the value now, but it may help remind
16389 future maintainers not to raise the value too much later.
16390 (SELECTION_QUANTUM): Remove, replacing with ...
16391 (selection_quantum): ... new function, which avoids overflow.
16393 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16394 assumption that selection length fits in 'int'.
16395 (x_reply_selection_request, x_handle_selection_request)
16396 (x_get_window_property, receive_incremental_selection)
16397 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
16398 (lisp_data_to_selection_data, clean_local_selection_data):
16399 Use ptrdiff_t, not int, to record length of selection.
16400 (x_reply_selection_request, x_get_window_property)
16401 (receive_incremental_selection, x_property_data_to_lisp):
16402 Redo calculations to avoid overflow.
16403 (x_reply_selection_request): When sending hint, ceiling it at
16404 X_LONG_MAX rather than relying on wraparound overflow to send
16406 (x_get_window_property, receive_incremental_selection)
16407 (lisp_data_to_selection_data, x_property_data_to_lisp):
16408 Check for size-calculation overflow.
16409 (x_get_window_property, receive_incremental_selection)
16410 (lisp_data_to_selection_data, Fx_register_dnd_atom):
16411 Don't store size until memory allocation succeeds.
16412 (x_get_window_property): Plug memory leak on memory exhaustion.
16413 Don't double-block input; malloc is safe here. Don't assume 2**34
16414 - 4 fits in unsigned long. Add an xassert to check
16415 XGetWindowProperty overflow. Be more careful about overflow
16416 calculations, and distinguish size from memory overflow better.
16417 (receive_incremental_selection): When tracing, don't assume
16418 unsigned int is less than INT_MAX.
16419 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16420 harmful) conversions of unsigned short to int.
16421 (lisp_data_to_selection_data): Don't assume that integers
16422 in the range -65535 through -1 fit in an X unsigned short.
16423 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16424 result parameters unless successful. Rely on cons_to_unsigned
16425 to report problems with elements; the old code wasn't right anyway.
16426 (x_check_property_data): Check for int overflow; we cannot use
16427 a wider type due to X limits.
16428 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
16430 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
16432 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
16433 (x_term_init): Check for size calculation overflow.
16434 (x_color_cells): Don't store size until memory allocation succeeds.
16435 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
16436 Don't assume alloca size is less than MAX_ALLOCA.

16459 * image.c (xpm_get_color_table_h):
16460 * lisp.h (hash_lookup, hash_put):
16461 * minibuf.c (Ftest_completion):
16462 Use ptrdiff_t for hash table indexes, not int (which is too
16463 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16464 32-bit --with-wide-int hosts).
16466 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16467 Add a FIXME comment about memory leaks.
16468 (syms_of_charset): Don't assume xmalloc returns.
16470 Don't assume that stated character widths fit in int.
16471 * character.c (Fchar_width, c_string_width, lisp_string_width):
16472 * character.h (CHAR_WIDTH):
16473 * indent.c (MULTIBYTE_BYTES_WIDTH):
16474 Use sanitize_char_width to avoid undefined and/or bad behavior
16475 with outlandish widths.
16476 * character.h (sanitize_tab_width): Rename from sanitize_width,
16477 now that we have two such functions. All uses changed.
16478 (sanitize_char_width): New inline function.
16480 Don't assume that tab-width fits in int.
16481 * character.h (sanitize_width): New inline function.
16482 (SANE_TAB_WIDTH): New macro.
16483 (ASCII_CHAR_WIDTH): Use it.

16489 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
16491 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
16492 Remove unreachable code.
16493 (read_hex, load_charset_map_from_file): Check for integer overflow.
16495 * xterm.c: Don't go over XClientMessageEvent limit.
16496 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16497 (x_send_scroll_bar_event): Likewise. Check that the size does not
16498 exceed limits imposed by XClientMessageEvent, as well as the usual
16499 ptrdiff_t and size_t limits.
16501 * keyboard.c: Overflow, signedness and related fixes.
16502 (make_lispy_movement): Use same integer type in forward decl
16503 that is used in the definition.
16504 (read_key_sequence, keyremap_step):
16505 Change bufsize argument back to int, undoing my 2011-03-30 change.
16506 We prefer signed types, and int is wide enough here.
16507 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16508 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16509 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16510 length, not size_t. Use ptrdiff_t for index, not int.
16511 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16512 possibility of integer overflow.
16514 Overflow, signedness and related fixes for images.

16533 when the callers expect that.
16534 (image_ascent): Redo ascent calculation to avoid int overflow.
16535 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
16536 (lookup_image): Remove unnecessary tests.
16537 (xbm_image_p): Locals are now of int, not EMACS_INT,
16538 since parse_image_check makes sure they fit into int.
16539 (png_load, gif_load, svg_load_image):
16540 Prefer int to unsigned where either will do.
16541 (tiff_handler): New function, combining the cores of the
16542 old tiff_error_handler and tiff_warning_handler.
16543 This function is rewritten to use vsnprintf and thereby avoid
16544 stack buffer overflows. It uses only the features of vsnprintf
16545 that are common to both POSIX and native Microsoft.
16546 (tiff_error_handler, tiff_warning_handler): Use it.
16547 (tiff_load, gif_load, imagemagick_load_image):
16548 Don't assume :index value fits in 'int'.
16549 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16550 (imagemagick_load_image): Check that crop parameters fit into
16551 the integer types that MagickCropImage accepts. Don't assume
16552 Vimagemagick_render_type has a nonnegative value. Don't assume
16553 size_t fits in 'long'.
16554 (gs_load): Use printmax_t to print the widest integers possible.
16555 Check for integer overflow when computing image height and width.

16564 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
16565 the display spec is of the form `(space ...)'.
16566 (handle_display_spec): Return the value returned by
16567 handle_single_display_spec, not just 1 or zero.
16568 (handle_single_display_spec): If the display spec is of the form
16569 `(space ...)', and specifies display in the text area, return 2
16571 (try_cursor_movement): Check for the need to scroll more
16572 accurately, and prefer exact match for point under bidi.
16573 Don't advance `row' beyond the last row of the window.
16575 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16576 into disp_prop; all users changed.
16578 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
16579 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
16580 for the text covered by the display property.

16590 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16591 buffers, return left-to-right.
16592 (set_cursor_from_row): Consider candidate row a win if its glyph
16593 represents a newline and point is on that newline. Fixes cursor
16594 positioning on the newline at EOL of R2L text within L2R
16595 paragraph, and vice versa.
16596 (try_cursor_movement): Check continued rows, in addition to
16597 continuation rows. Fixes unwarranted scroll when point enters a
16598 continued line of R2L text within an L2R paragraph, or vice versa.
16599 (cursor_row_p): Consider the case of point being equal to
16600 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16601 from the end of a short line to the beginning of a continued line
16602 of R2L text within L2R paragraph.
16603 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
16604 composed characters.

16617 * nsfont.m (ns_otf_to_script): Fix typo.
16619 2011-08-22 Kenichi Handa <handa@m17n.org>
16621 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
16622 extra slot even if the purpose is char-code-property-table.
16624 2011-08-23 Eli Zaretskii <eliz@gnu.org>
16626 * xdisp.c (redisplay_window): When computing centering_position,
16627 account for the height of the header line. (Bug#8874)
16629 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16630 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16631 candidate is selected by the mouse, and that candidate has a
16632 composed character under the mouse.
16634 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16635 coordinates reported by pos-visible-in-window-p for a composed
16636 character in column zero.
16638 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
16640 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
16642 2011-08-22 Eli Zaretskii <eliz@gnu.org>
16644 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16645 consider it a hit if to_charpos is anywhere in the range of the
16646 composed buffer positions.
16648 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16650 * image.c (gif_load): Don't assume that each subimage has the same
16651 dimensions as the base image. Handle disposal method that is
16652 "undefined" by the gif spec (Bug#9335).
16654 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16656 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16659 2011-08-19 Eli Zaretskii <eliz@gnu.org>
16661 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16662 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16663 from an Org mode buffer to a Speedbar frame.
16665 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16666 a composition, take its buffer position from IT->cmp_it.charpos.
16667 Fixes cursor positioning at the beginning of a line that begins
16668 with a composed character.
16670 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16672 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16673 character bidirectional type, use STRONG_L instead. Fixes crashes
16674 in a buffer produced by `describe-categories'.
16676 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16677 members before the level stack, so they would be saved and
16678 restored when copying iterator state. Fixes incorrect reordering
16679 around TABs covered by display properties.
16681 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16683 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16689 Remove unnecessary aborts (Bug#9081).
16691 2011-08-17 Eli Zaretskii <eliz@gnu.org>
16693 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
16694 has no `load' handler, try opening the file locally. (Bug#9311)
16696 2011-08-16 Ken Brown <kbrown@cornell.edu>
16698 * gmalloc.c: Expand comment.
16700 2011-08-16 Eli Zaretskii <eliz@gnu.org>
16702 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
16703 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.

16748 * process.c (create_process): Call setup_process_coding_systems
16749 after the pid of the process is set to -1 (Bug#8162).
16751 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16753 * xdisp.c (move_it_in_display_line_to): Don't invoke
16754 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16755 ppos_it. Fixes vertical cursor motion when line beginning is
16756 covered by an image. (Bug#9296)
16758 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16760 * nsterm.h (ns_run_ascript): Declare.

16764 (ns_run_ascript): New function.
16765 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16766 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16767 the event loop. Get status from as_status (Bug#7276).
16769 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16770 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16771 the event loop (Bug#7276).
16773 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

16796 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16797 (Fnetwork_interface_list): Allocate in increments of bytes instead
16798 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16799 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16801 (struct ifflag_def): notrailers is smart on OSX.
16802 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16803 Get hardware address with getifaddrs if available.
16805 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16807 * xdisp.c (iterate_out_of_display_property): xassert that
16808 IT->position is set to within IT->object's boundaries. Break from
16809 the loop as soon as EOB is reached; avoids infloops in redisplay
16810 when IT->position is set up wrongly due to some bug.
16811 Set IT->current to match the bidi iterator unconditionally.
16812 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16813 entry. Force push_it to save on the stack the current
16814 buffer/string position, to be restored by pop_it. Fix flags in
16815 the iterator structure wrt the object coming from a display
16816 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16817 properties. (Bug#9284)
16819 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16821 * fontset.c (fontset_get_font_group): Add proper type checks.

16834 no-display-properties-and-no-overlays under bidi display.
16835 Set disp_pos in the bidi iterator to avoid searches for display
16836 properties and overlays.
16838 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16840 * editfns.c (Fset_time_zone_rule): Document relationship with the
16843 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16844 the font entity extracted from the cache (Bug#8109).
16846 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16848 * composite.c (autocmp_chars): Don't reset point. That is done by
16849 restore_point_unwind (Bug#5984).
16851 2011-08-07 Juri Linkov <juri@jurta.org>
16853 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16854 to show the arg `TIME' instead of `TIMEVAL'.
16856 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16858 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16859 display property strides EOL and includes a newline, as in
16860 longlines-mode. (Bug#9254)
16861 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16862 word-wrap under bidirectional display. (Bug#9224)
16864 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16865 is non-zero, even if the data buffer is NULL. Fixes a crash in
16866 vertical-motion with longlines-mode. (Bug#9254)
16868 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16870 * bidi.c <bidi_cache_total_alloc>: Now static.
16871 (bidi_initialize): Initialize bidi_cache_total_alloc.
16873 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16876 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16877 amount allocated this far in `bidi_cache_total_alloc'.
16878 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16879 non-zero, only free the data buffer without restoring the cache
16880 contents. All callers changed.
16882 * dispextern.h (bidi_unshelve_cache): Update prototype.
16884 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16885 (move_it_in_display_line, move_it_to)
16886 (move_it_vertically_backward, move_it_by_lines): Replace the call
16887 to xfree to an equivalent call to bidi_unshelve_cache.
16888 (move_it_in_display_line_to): Fix logic of returning
16889 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16891 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16893 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16894 came from a string character with a `cursor' property. (Bug#9229)
16896 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16898 * Makefile.in (LIB_PTHREAD): New variable.
16899 (LIBES): Add LIB_PTHREAD (Bug#9216).
16901 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16902 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).

16906 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16908 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16910 * xterm.c (x_find_topmost_parent): New function.
16911 (x_set_frame_alpha): Find topmost parent window with
16912 x_find_topmost_parent and set the property there also (bug#9181).
16913 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16915 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16917 * callproc.c (Fcall_process): Avoid vfork clobbering
16918 the local vars buffer, coding_systems, current_dir.
16920 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16922 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16924 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16926 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16927 so that it is not optimized away.
16929 * xdisp.c (compute_display_string_pos): Remove unused local.
16931 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16933 Fix slow cursor motion and scrolling in large buffers with
16934 selective display, like Org Mode buffers. (Bug#9218)
16936 * dispextern.h (struct bidi_it): New member disp_prop_p.
16938 * xdisp.c: Remove one-slot cache of display string positions.
16939 (compute_display_string_pos): Accept an additional argument
16940 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16941 for a display string or property. If found, set DISP_PROP_P
16944 * bidi.c (bidi_fetch_char): Accept an additional argument
16945 DISP_PROP_P, and pass it to compute_display_string_pos.
16946 Only handle text covered by a display string if DISP_PROP_P is returned
16947 non-zero. All callers of bidi_fetch_char changed.
16949 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16951 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16953 2010-12-03 Don March <don@ohspite.net>
16955 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16956 last character M-[char] is translated to ESC [char] (bug#7541).
16958 2011-08-02 Kenichi Handa <handa@m17n.org>
16960 * lisp.h (uniprop_table): Extern it.
16962 * chartab.c (uniprop_table): Make it non-static.
16964 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16966 * xdisp.c (forward_to_next_line_start): Accept additional argument
16967 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16969 (reseat_at_next_visible_line_start): Use the bidi iterator state
16970 returned by forward_to_next_line_start to restore the state of
16971 it->bidi_it after backing up to previous newline. (Bug#9212)
16973 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16975 * regex.c (re_comp): Protoize.
16976 (re_exec): Fix return type.
16977 (regexec): Fix type of `ret'. (Bug#9203)
16979 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16981 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16982 This is needed if max-image-size is a floating-point number.
16984 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16986 * print.c (print_object): Print empty symbol as ##.
16988 * lread.c (read1): Read ## as empty symbol.
16990 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16992 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16993 setting frame foreground color (Bug#9175).
16994 (x_set_background_color): Likewise.
16996 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16997 contents (Bug#9176).
16998 (EmacsTooltip -init): Remove bezels and add shadows to
17001 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17002 or scroll bar (Bug#8470).
17004 * nsfont.m (nsfont_open): Remove assignment to voffset and
17005 unnecessary vars hshink, expand, hd, full_height, min_height.
17006 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17008 * nsterm.h (nsfont_info): Remove voffset field.
17010 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17012 Implement strike-through and overline on NextStep (Bug#8863).
17014 * nsfont.m (nsfont_open): Use underline position provided by font,
17015 instead of hard-coded value of 2.
17016 (nsfont_draw): Call ns_draw_text_decoration instead.
17018 * nsterm.h: Add declaration for ns_draw_text_decoration.
17020 * nsterm.m (ns_draw_text_decoration): New function for drawing
17021 underline, overline, and strike-through.
17022 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17023 ns_draw_text_decoration. Change treatment of cursor drawing to
17024 accommodate underlining, etc.
17026 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17028 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17031 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17033 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17034 Without this fix, if a signal arrives just after memory fills up,
17035 'malloc' might be invoked reentrantly.
17037 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17038 In other words, assume that every image size is allowed, on non-X
17039 hosts. This assumption is probably wrong, but it lets Emacs compile.
17041 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17043 * regex.c (re_iswctype): Convert return values to boolean.
17045 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17047 * xdisp.c (compute_display_string_pos): Don't use cached display
17048 string position if the buffer had its restriction changed.
17051 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17053 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17055 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17057 Integer signedness and overflow and related fixes. (Bug#9079)
17059 * bidi.c: Integer size and overflow fixes.
17060 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17061 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17062 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17063 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17064 (bidi_find_other_level_edge):
17065 Use ptrdiff_t instead of EMACS_INT where either will do.
17066 This works better on 32-bit hosts configured --with-wide-int.
17067 (bidi_cache_ensure_space): Check for size-calculation overflow.
17068 Use % rather than repeated addition, for better worst-case speed.
17069 Don't set bidi_cache_size until after xrealloc returns, because it
17071 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17072 (bidi_cache_ensure_space): Also check that the bidi cache size
17073 does not exceed that of the largest Lisp string or buffer. See Eli
17074 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17076 * alloc.c (__malloc_size_t): Remove.
17077 All uses replaced by size_t. See Andreas Schwab's note
17078 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17080 * image.c: Improve checking for integer overflow.
17081 (check_image_size): Assume that f is nonnull, since
17082 it is always nonnull in practice. This is one less thing to
17083 worry about when checking for integer overflow later.
17084 (x_check_image_size): New function, which checks for integer
17085 overflow issues inside X.
17086 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17087 This removes the need for a memory_full check.
17088 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17089 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17090 (xbm_read_bitmap_data): Change locals back to 'int', since
17091 their values must fit in 'int'.
17092 (xpm_load_image, png_load, tiff_load):
17093 Invoke x_create_x_image_and_pixmap earlier,
17094 to avoid much needless work if the image is too large.
17095 (tiff_load): Treat overly large images as if
17096 x_create_x_image_and_pixmap failed, not as malloc failures.
17097 (gs_load): Use x_check_image_size.
17099 * gtkutil.c: Omit integer casts.
17100 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17101 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17103 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17105 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17106 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17107 would wrongly return t on a 64-bit host.
17109 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17110 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17111 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17112 and therefore cause GCC to emit a bogus diagnostic in some cases.
17114 * image.c: Integer signedness and overflow and related fixes.
17115 This is not an exhaustive set of fixes, but it's time to
17116 record what I've got.
17117 (lookup_pixel_color, check_image_size): Remove redundant decls.
17118 (check_image_size): Don't assume that arbitrary EMACS_INT values
17119 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17120 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17121 (tiff_load, imagemagick_load_image):
17122 Check for overflow in size calculations.
17123 (x_create_x_image_and_pixmap): Remove unnecessary test for
17124 xmalloc returning NULL; that can't happen.
17125 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17126 (xpm_color_bucket): Use better integer hashing function.
17127 (xpm_cache_color): Don't possibly over-allocate memory.
17128 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17129 (gif_memory_source):
17130 Use ptrdiff_t, not int or size_t, to record sizes.
17131 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17132 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17133 either works, as we prefer signed integers.
17134 (tiff_read_from_memory, tiff_write_from_memory):
17135 Return tsize_t, not size_t, since that's what the TIFF API wants.
17136 (tiff_read_from_memory): Don't fail simply because the read would
17137 go past EOF; instead, return a short read.
17138 (tiff_load): Omit no-longer-needed casts.
17139 (Fimagemagick_types): Don't assume size fits into 'int'.
17141 Improve hashing quality when configured --with-wide-int.
17142 * fns.c (hash_string): New function, taken from sxhash_string.
17143 Do not discard information about ASCII character case; this
17144 discarding is no longer needed.
17145 (sxhash-string): Use it. Change sig to match it. Caller changed.
17146 * lisp.h: Declare it.
17147 * lread.c (hash_string): Remove, since we now use fns.c's version.
17148 The fns.c version returns a wider integer if --with-wide-int is
17149 specified, so this should help the quality of the hashing a bit.
17151 * emacs.c: Integer overflow minor fix.
17152 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17153 Define only if GNU_LINUX.
17154 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17156 * dispnew.c: Integer signedness and overflow fixes.
17157 Remove unnecessary forward decls, that were a maintenance hassle.
17158 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17160 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17161 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17162 (prepare_desired_row, line_draw_cost):
17163 Use int, not unsigned, where either works.
17164 (save_current_matrix, restore_current_matrix):
17165 Use ptrdiff_t, not size_t, where either works.
17166 (init_display): Check for overflow more accurately, and without
17167 relying on undefined behavior.
17169 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17170 Remove, replacing with the new symbols in lisp.h. All uses changed.
17171 * fileio.c (make_temp_name):
17172 * filelock.c (lock_file_1, lock_file):
17173 * xdisp.c (message_dolog):
17174 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17175 Use pMd etc. instead.
17176 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17177 replacing the pWIDE etc. symbols removed from editfns.c.
17179 * keyboard.h (num_input_events): Now uintmax_t.
17180 This is (very slightly) less likely to mess up due to wraparound.
17183 * buffer.c: Integer signedness fixes.
17184 (alloc_buffer_text, enlarge_buffer_text):
17185 Use ptrdiff_t rather than size_t when either will do, as we prefer
17188 * alloc.c: Integer signedness and overflow fixes.
17189 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17190 (__malloc_size_t): Default to size_t, not to int.
17191 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17192 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17193 Prefer ptrdiff_t to size_t when either would do, as we prefer
17195 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17196 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17197 Now const. Initialize with values that are in range even if char
17199 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17200 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17201 These functions do the right thing with sizes > 2**32.
17202 (check_depth): Now ptrdiff_t, not int.
17203 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17204 Adjust to new way of storing sizes. Check for size overflow bugs
17206 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17207 slightly wrong anyway, as it missed one instance of
17208 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17209 (refill_memory_reserve): Omit needless cast to size_t.
17210 (mark_object_loop_halt): Mark as externally visible.
17212 * xselect.c: Integer signedness and overflow fixes.
17213 (Fx_register_dnd_atom, x_handle_dnd_message):
17214 Use ptrdiff_t, not size_t, since we prefer signed.
17215 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17216 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17217 x_dnd_atoms_size and x_dnd_atoms_length.
17219 * doprnt.c: Prefer signed to unsigned when either works.
17221 * doprnt.c (doprnt):
17223 * xdisp.c (vmessage):
17224 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17225 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17226 prefer signed arithmetic to avoid comparison confusion.
17227 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17228 but is a bit tricky.
17230 Assume freestanding C89 headers, string.h, stdlib.h.
17231 * data.c, doprnt.c, floatfns.c, print.c:
17232 Include float.h unconditionally.
17233 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17234 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17235 * regex.c: Likewise for stddef.h, string.h.
17236 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17237 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17238 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17239 (STDC_HEADERS): Remove obsolete defines.
17240 * sysdep.c: Include limits.h unconditionally.
17242 Assume support for memcmp, memcpy, memmove, memset.
17243 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17244 * regex.c (memcmp, memcpy):
17245 Remove; we assume C89 now.
17247 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17248 (__malloc_safe_bcopy): Remove; no longer needed.
17250 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17251 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17252 well either way, and we prefer signed to unsigned.
17254 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17256 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17257 closes the connection while we're reading (bug#9182).
17259 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17261 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17262 are specified (Bug#9168).
17264 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17266 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17267 Found by GCC static checking and --with-wide-int on a 32-bit host.
17269 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17271 * xdisp.c (compute_display_string_pos): Fix logic of caching
17272 previous display string position. Initialize cached_prev_pos to
17273 -1. Fixes slow-down at the beginning of a buffer.
17275 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17277 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17278 for attrs[LFACE_FONTSET_INDEX].
17280 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17282 * xml.c (parse_region): Remove unused local
17283 that was recently introduced.
17285 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17287 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17288 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17290 * xdisp.c (move_it_in_display_line_to): Record the best matching
17291 position for TO_CHARPOS while scanning the line, and restore it on
17292 exit if none of the characters scanned was an exact match.
17293 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17294 when exact match is impossible due to invisible text, and the
17295 lines are truncated.
17297 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17299 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17302 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17304 Fix a significant slow-down of cursor motion with C-n, C-p,
17305 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17306 auto-repeat under bidi redisplay in fontified buffers.
17307 * xdisp.c (compute_stop_pos_backwards): New function.
17308 (next_element_from_buffer): Call compute_stop_pos_backwards to
17309 find a suitable prev_stop when we find ourselves before
17311 (reseat): Don't look for prev_stop, as that could mean a very long
17313 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17314 <cached_disp_overlay_modiff>: Cache for last found display string
17316 (compute_display_string_pos): Return the cached position if asked
17317 about the same buffer in the same area of character positions, and
17318 the buffer wasn't changed since the time the display string
17319 position was cached.
17321 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17323 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17324 is an integer, which is important for empty lines. (Bug#9149)
17326 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17328 * frame.c (Fmodify_frame_parameters): In tty case, update the
17329 default face if necessary (Bug#4238).
17331 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17333 * editfns.c (Fstring_to_char): No need to explain what a character
17334 is in the docstring (Bug#6576).
17336 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17338 * xml.c (parse_region): Make sure we always return a tree.
17340 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17342 * xml.c (parse_region): If a document contains only comments,
17345 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17347 * xml.c (make_dom): Return comments, too.

17354 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17355 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17356 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17358 * s/openbsd.h (BROKEN_SIGIO): Define.
17359 * unexelf.c (unexec) [__OpenBSD__]:
17360 Don't update the .mdebug section of the Alpha COFF symbol table.
17362 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17364 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17367 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17369 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17370 This fixes some race conditions on the permissions of any newly
17373 * alloc.c (valid_pointer_p): Use pipe, not open.
17374 This fixes some permissions issues when debugging.
17376 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17377 If fchown fails to set both uid and gid, try to set just gid,
17378 as that is sometimes allowed. Adjust the file's mode to eliminate
17379 setuid or setgid bits that are inappropriate if fchown fails.
17381 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17383 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

17389 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17391 * lread.c (read_integer): Unread even EOF character.
17392 (read1): Likewise. Properly record start position of symbol.
17394 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17395 symbol character follows.
17397 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17399 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17400 This works around a problem with the previous change to Fcopy_file.
17401 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17402 and without this change, GCC might complain about discarding
17403 fchown's return value.
17405 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17407 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17409 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17411 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17413 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17415 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17416 it's used from the C level.
17418 * process.c: Use the same condition for POLL_FOR_INPUT in both
17419 keyboard.c and process.c (bug#1858).
17421 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17423 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17424 (Fgnutls_boot): Use it.
17426 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17428 * doc.c (Fsubstitute_command_keys): Revert last change.
17430 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17432 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17433 quotes the next character, and doesn't affect other longer
17434 sequences (bug#8935).
17436 * lread.c (syms_of_lread): Clarify that is isn't only
17437 `eval-buffer' and `eval-defun' that's affected by
17438 `lexical-binding' (bug#8460).
17440 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17442 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17443 bidi redisplay when a line includes both an image and is truncated.
17445 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17447 Fix minor problems found by static checking.
17448 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17449 (elsz): Now a signed constant, not a size_t var. We prefer signed
17450 types to unsigned, to avoid integer comparison confusion. Without
17451 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17452 "cannot optimize loop, the loop counter may overflow", a symptom
17454 * indent.c (Fvertical_motion): Mark locals as initialized.
17455 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17457 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17459 * search.c (Fre_search_backward): Mention `case-fold-search' in
17460 all the re_search_* functions (bug#8138).

17483 (display_string): If we need to ignore text properties of
17484 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17485 original value of -1 will not work with bidi.)
17486 (compute_display_string_pos): First arg is now struct
17487 `text_pos *'; all callers changed. Support display properties on
17489 (compute_display_string_end): Support display properties on Lisp
17491 (init_iterator, reseat_1, reseat_to_string): Initialize the
17492 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17493 when iterating on a string not from display properties).
17494 (compute_display_string_pos, compute_display_string_end):
17495 Fix calculation of the object to scan. Fixes an error when using
17497 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17498 base_level_stop; instead, set base_level_stop to BEGV.
17499 Fixes crashes in vertical-motion.
17500 (next_element_from_buffer): Improve commentary for when
17501 the iterator is before prev_stop.
17502 (init_iterator): Initialize bidi_p from the default value of
17503 bidi-display-reordering, not from buffer-local value. Use the
17504 buffer-local value only if initializing for buffer iteration.

17525 parts of next_element_from_buffer, next_element_from_string, and
17526 next_element_from_c_string.
17527 (tool_bar_lines_needed, redisplay_tool_bar)
17528 (display_menu_bar): Force left-to-right direction. Add a FIXME

17543 pushed the iterator stack, restore the internal state of the bidi
17544 iterator by calling bidi_pop_it same number of times.
17545 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17546 and we are bidi-iterating, don't decrement the iterator position;
17547 instead, set the first_elt flag in the bidi iterator, to produce
17549 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17550 (push_display_prop): xassert that we are iterating a buffer.

17554 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17555 correctly. Don't assume unibyte strings are not bidi-reordered.

17564 property. Fix a typo in popping stretch info. Add an assertion
17565 for verifying that the iterator position is in sync with the bidi
17567 (handle_single_display_spec, get_overlay_strings_1)

17656 (bidi_push_it, bidi_pop_it): Add prototypes.
17657 (struct iterator_stack_entry): New members bidi_p,
17658 paragraph_embedding, and from_disp_prop_p.

17712 The old code sometimes used this field without initializing it.
17714 * alloc.c (gc_sweep): Don't read past end of array.

17979 (clone_per_buffer_values): Don't assume that

17981 This isn't true in general, and it's particularly not true
17982 if Emacs is configured with --with-wide-int.
17983 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
17984 New macros, used in the buffer.c change.

18020 Random fixes. E.g., (random) never returned negative values.
18021 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18022 subseconds part to the entropy, as that's a bit more random.
18023 Prefer signed to unsigned, since the signedness doesn't matter and
18024 in general we prefer signed. When given a limit, use a
18025 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18026 latter isn't right if USE_2_TAGS_FOR_INTS.
18027 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18028 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18032 * textprop.c (text_property_stickiness):

18040 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18041 This is more efficient than Ffile_directory_p and avoids a minor race.
18043 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18045 * buffer.c (Foverlay_put): Say what the return value is
18048 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18049 is a directory before asking whether to use the file name

18052 error be more correct.
18054 * fns.c (Frequire): Remove the mention of the .gz files, since
18055 that's installation-specific, but keep the mention of
18056 `get-load-suffixes'.

18060 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

18068 Qgnutls_bootprop_verify_error (which is no longer used).
18070 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18071 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18072 Also (re)move comments that are misplaced or no longer relevant.

18101 * lread.c (syms_of_lread): Mention single symbols defined by

18135 (syms_of_keymap): Defsubr make-composed-keymap.
18136 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

18173 * eval.c (struct backtrace): Simplify and port the data structure.
18174 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18175 signed bit field, as this assumption is not portable and it makes
18176 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18177 "char debug_on_exit : 1" as this is not portable either; instead,
18178 use the portable "unsigned int debug_on_exit : 1". Remove unused
18179 member evalargs. Remove obsolete comments about cc bombing out.
18181 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18267 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
18269 * process.c (wait_reading_process_output): Bypass select if
18270 waiting for a cell while ignoring keyboard input, and input is
18271 pending. Suggested by Jan Djärv (Bug#8869).
18273 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
18275 Use gnulib's dup2 module instead of rolling our own.
18276 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

18347 * print.c (printchar, strout): Check for string overflow.
18348 (PRINTPREPARE, printchar, strout):
18349 Don't set size unless allocation succeeds.
18351 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18352 for sizes. Check for string overflow more accurately.
18353 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
18355 * macros.c: Integer and buffer overflow fixes.
18356 * keyboard.h (struct keyboard.kbd_macro_bufsize):
18357 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

18361 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
18363 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
18365 * lread.c: Integer overflow fixes.
18366 (read_integer): Radix is now EMACS_INT, not int,
18367 to improve quality of diagnostics for out-of-range radices.
18368 Calculate buffer size correctly for out-of-range radices.
18369 (read1): Check for integer overflow in radices, and in
18370 read-circle numbers.
18371 (read_escape): Avoid int overflow.
18372 (Fload, openp, read_buffer_size, read1)
18373 (substitute_object_recurse, read_vector, read_list, map_obarray):

18389 2011-06-22 Leo Liu <sdl.web@gmail.com>
18391 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
18392 Move to minibuffer.el.
18394 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18396 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18397 The following patches are for when GLYPH_DEBUG && !XASSERT.
18398 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18399 * dispnew.c (flush_stdout):
18400 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18401 Mark as externally visible.
18402 * dispnew.c (check_window_matrix_pointers): Now static.
18403 * dispnew.c (window_to_frame_vpos):
18404 * xfns.c (unwind_create_frame):

18406 * scroll.c (CHECK_BOUNDS):
18407 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18408 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18409 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18410 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18411 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18413 (debug_method_add): Use va_list and vsprintf rather than relying
18414 on undefined behavior with wrong number of arguments.
18415 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18416 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18417 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18418 since we're not interested in debugging glyphs with old libraries.
18419 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18420 GCC 4.6.0's static checking.
18422 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

18440 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18441 (.bitmaps_last, struct x_output.icon_bitmap):
18442 Use ptrdiff_t, not int, for bitmap indexes.
18443 (x_allocate_bitmap_record): Check for size overflow.
18444 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18446 Use ptrdiff_t, not int, for overlay counts.
18447 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18448 * editfns.c (overlays_around, get_pos_property):

18450 * xdisp.c (next_overlay_change, note_mouse_highlight):
18451 * xfaces.c (face_at_buffer_position):
18452 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18453 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18454 (Fnext_overlay_change, Fprevious_overlay_change)
18455 (mouse_face_overlay_overlaps, Foverlays_in):
18456 Use ptrdiff_t, not int, for sizes.
18457 (overlays_at, overlays_in): Check for size-calculation overflow.
18459 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18461 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18462 (x_session_initialize): Do not assume string length fits in int.
18464 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18465 This is unlikely, but can occur if DPI is outlandish.
18467 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18468 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

18471 * xrdb.c (magic_file_p, search_magic_path):
18472 Omit last arg SUFFIX; it was always 0. All callers changed.
18473 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18475 * xfont.c (xfont_match): Avoid need for strlen.
18477 * xfns.c: Don't assume strlen fits in int.

18480 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18481 not unsigned long, as we prefer signed integers. All callers changed.
18482 Detect integer overflow in repeat count.
18483 (message_dolog): Don't assume print length fits in 39 bytes.
18484 (display_mode_element): Don't assume strlen fits in int.
18486 * termcap.c: Don't assume sizes fit in int and never overflow.
18487 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18488 (gobble_line): Check for size-calculation overflow.
18490 * minibuf.c (Fread_buffer):
18491 * lread.c (intern, intern_c_string):

18505 * filelock.c: Fix some buffer overrun and integer overflow issues.
18506 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18507 Reformulate so as not to need the command string.
18508 Invoke gzip -cd rather than gunzip, as it's more portable.
18509 (lock_info_type, lock_file_1, lock_file):
18510 Don't assume pid_t and time_t fit in unsigned long.
18511 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18512 (current_lock_owner): Prefer signed type for sizes.
18513 Use memcpy, not strncpy, where memcpy is what is really wanted.
18514 Don't assume (via atoi) that time_t and pid_t fit in int.
18515 Check for time_t and/or pid_t out of range, e.g., via a network share.
18516 Don't alloca where an auto var works fine.
18518 * fileio.c: Fix some integer overflow issues.
18519 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18520 Don't assume string length fits in int.
18521 (directory_file_name): Don't assume string length fits in long.
18522 (make_temp_name): Don't assume pid fits in int, or that its print
18523 length is less than 20.

18543 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18545 * lread.c (invalid_syntax): Omit length argument.
18546 All uses changed. This doesn't fix a bug, but it simplifies the
18547 code away from its former Hollerith-constant appearance, and it's
18548 one less 'int' to worry about when looking at integer-overflow issues.
18549 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18551 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18552 This didn't break anything, but it didn't help either.
18553 It's confusing to put a bogus integer in a place where the actual
18554 value does not matter.
18555 (LIST_END_P): Remove unused macro and its bogus comment.
18556 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18558 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18559 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18561 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18562 We prefer signed types, and the value cannot exceed the EMACS_INT
18563 range anyway (because otherwise the length would not be representable).
18564 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18565 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18566 This avoids a GCC warning when WIDE_EMACS_INT.
18568 * indent.c (sane_tab_width): New function.
18569 (current_column, scan_for_column, Findent_to, position_indentation)
18570 (compute_motion): Use it. This is just for clarity.
18571 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.

18577 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18579 * editfns.c, insdel.c:
18580 Omit unnecessary forward decls, to simplify future changes.
18582 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18584 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18586 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18587 Use much-faster test for byte-length change.
18588 Don't assume string byte-length fits in 'int'.
18589 Check that character arg fits in 'int'.
18590 (mapcar1): Declare byte as byte, for clarity.
18592 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18594 * fns.c (concat): Catch string overflow earlier.
18595 Do not rely on integer wraparound.
18597 * dispextern.h (struct it.overlay_strings_charpos)
18598 (struct it.selective): Now EMACS_INT, not int.
18599 * xdisp.c (forward_to_next_line_start)
18600 (back_to_previous_visible_line_start)
18601 (reseat_at_next_visible_line_start, next_element_from_buffer):
18602 Don't arbitrarily truncate the value of 'selective' to int.
18604 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18606 * composite.c: Don't truncate sizes to 'int'.
18607 (composition_gstring_p, composition_reseat_it)
18608 (composition_adjust_point): Use EMACS_INT, not int.
18609 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18610 not EMACS_UINT, for indexes.
18612 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18614 * buffer.c: Include <verify.h>.
18615 (struct sortvec.priority, struct sortstr.priority):
18616 Now EMACS_INT, not int.
18617 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18618 (struct sortstr.size, record_overlay_string)
18619 (struct sortstrlist.size, struct sortlist.used):
18620 Don't truncate size to int.
18621 (record_overlay_string): Check for size-calculation overflow.
18622 (init_buffer_once): Check at compile-time, not run-time.
18624 2011-06-22 Jim Meyering <meyering@redhat.com>
18626 Don't leak an XBM-image-sized buffer
18627 * image.c (xbm_load): Free the image buffer after using it.
18629 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18632 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18633 that Sun C diagnosed.
18634 * fns.c (secure_hash): Fix pointer signedness issue.
18635 * intervals.c (static_offset_intervals): New function.
18636 (offset_intervals): Use it.
18638 2011-06-21 Leo Liu <sdl.web@gmail.com>
18641 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18644 * fns.c (secure_hash): Rename from crypto_hash_function and change
18645 the first arg to accept symbols.
18646 (Fsecure_hash): New primitive.
18647 (syms_of_fns): New symbols.
18649 2011-06-20 Deniz Dogan <deniz@dogan.se>
18651 * process.c (Fset_process_buffer): Clarify return value in

18666 check till after the cache is created in init_frame_faces.
18668 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18670 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18672 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18674 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18675 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18676 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18678 Improve buffer-overflow checking (Bug#8873).
18679 * fileio.c (Finsert_file_contents):
18680 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18681 Remove the old (too-loose) buffer overflow checks.
18682 They weren't needed, since make_gap checks for buffer overflow.
18683 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18684 The old code merely checked for Emacs fixnum overflow, and relied
18685 on undefined (wraparound) behavior. The new code avoids undefined
18686 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18688 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18689 Tune. Don't use wider integers than needed. Don't use alloca.
18690 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18692 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18694 * insdel.c, lisp.h (buffer_overflow): New function.
18695 (insert_from_buffer_1, replace_range, replace_range_2):
18696 * insdel.c (make_gap_larger):
18697 * editfns.c (Finsert_char):
18698 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18700 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18702 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18704 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18706 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18707 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18709 * fileio.c: Don't assume EMACS_INT fits in off_t.
18710 (emacs_lseek): New static function.
18711 (Finsert_file_contents, Fwrite_region): Use it.
18712 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18714 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18716 * fns.c: Don't overflow int when computing a list length.
18717 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18718 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18719 truncation on 64-bit hosts. Check for QUIT every
18720 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18721 faster and is responsive enough.
18722 (Flength): Report an error instead of overflowing an integer.
18723 (Fsafe_length): Return a float if the value is not representable
18724 as a fixnum. This shouldn't happen except in contrived situations.
18725 (Fnthcdr, Fsort): Don't assume list length fits in int.
18726 (Fcopy_sequence): Don't assume vector length fits in int.
18728 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18729 (header_size, word_size): New constants.
18730 (allocate_vectorlike): Don't check size overflow here.
18731 (allocate_vector): Check it here instead, since this is the only
18732 caller of allocate_vectorlike that could cause overflow.
18733 Check that the new vector's length is representable as a fixnum.
18735 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18736 The previous code was bogus. For example, next_almost_prime (32)
18737 returned 39, which is undesirable as it is a multiple of 3; and
18738 next_almost_prime (24) returned 25, which is a multiple of 5 so
18739 why was the code bothering to check for multiples of 7?
18741 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18743 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18745 Variadic C functions now count arguments with ptrdiff_t.
18746 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18747 Back then I didn't know that the Emacs coding style prefers signed int.
18748 Also, in the meantime I found a few more instances where arguments
18749 were being counted with int, which may truncate counts on 64-bit
18750 machines, or EMACS_INT, which may be unnecessarily wide.
18751 * lisp.h (struct Lisp_Subr.function.aMANY)
18752 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18753 Arg counts are now ptrdiff_t, not size_t.
18754 All variadic functions and their callers changed accordingly.
18755 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18756 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18757 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18758 * callint.c (Fcall_interactively): Check arg count for overflow,
18759 to avoid potential buffer overrun. Use signed char, not 'int',
18760 for 'varies' array, so that we needn't bother to check its size
18761 calculation for overflow.
18762 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18763 * eval.c (apply_lambda):
18764 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18765 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18766 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18768 * callint.c (Fcall_interactively): Don't use index var as event count.
18770 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18771 * mem-limits.h (SIZE): Remove; no longer used.
18773 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18775 Remove unnecessary casts.
18776 * xterm.c (x_term_init):
18777 * xfns.c (x_set_border_pixel):
18778 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18779 These aren't needed now that we assume ANSI C.
18781 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18782 It's more likely to cause problems (due to unsigned overflow)
18785 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18787 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18789 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18791 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18793 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18795 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18797 GLYPH_CODE_FACE returns EMACS_INT, not int.
18798 * dispextern.h (merge_faces):
18799 * xfaces.c (merge_faces):
18800 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18801 Don't assume EMACS_INT fits in int.
18803 * character.h (CHAR_VALID_P): Remove unused parameter.
18804 * fontset.c, lisp.h, xdisp.c: All uses changed.
18806 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18808 * fns.c (concat): Minor tuning based on overflow analysis.
18809 This doesn't fix any bugs. Use int to hold character, instead
18810 of constantly refetching from Emacs object. Use XFASTINT, not
18811 XINT, for value known to be a character. Don't bother comparing
18812 a single byte to 0400, as it's always less.
18814 * floatfns.c (Fexpt):
18815 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18817 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18820 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18822 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18823 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18824 incorrectly succeed when S was a string, because 4294967386 was
18825 truncated before it was used.
18827 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18828 Otherwise, an out-of-range integer could cause undefined behavior
18831 * composite.c: Use int, not EMACS_INT, for characters.
18832 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18833 EMACS_INT, for values that are known to be in character range.
18834 This doesn't fix any bugs but is the usual style inside Emacs and
18835 may generate better code on 32-bit machines.
18837 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18838 This is for reasons similar to the recent CHAR_STRING fix.
18839 * charset.c (Fencode_char): Check that character arg is actually
18840 a character. Pass an int to ENCODE_CHAR.
18841 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18842 wider than 'int', as a compile-time check to prevent future regressions
18845 * character.c (char_string): Remove unnecessary casts.
18847 Make sure a 64-bit char is never passed to CHAR_STRING.
18848 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18849 by silently ignoring the top 32 bits, allowing some values
18850 that were far too large to be valid characters.
18851 * character.h: Include <verify.h>.
18852 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18853 arguments are no wider than unsigned, as a compile-time check
18854 to prevent future regressions in this area.
18856 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18857 (Fsubst_char_in_region):
18859 * xdisp.c (decode_mode_spec_coding):
18860 Adjust to CHAR_STRING's new requirement.
18861 * editfns.c (Finsert_char, Fsubst_char_in_region):
18862 * fns.c (concat): Check that character args are actually
18863 characters. Without this test, these functions did the wrong
18864 thing with wildly out-of-range values on 64-bit hosts.
18866 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18867 These casts should not be needed on 32-bit hosts, either.
18868 * keyboard.c (read_char):
18869 * lread.c (Fload): Remove casts to unsigned.
18871 * lisp.h (UNSIGNED_CMP): New macro.
18872 This fixes comparison bugs on 64-bit hosts.
18873 (ASCII_CHAR_P): Use it.
18874 * casefiddle.c (casify_object):
18875 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18876 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18877 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18878 * dispextern.h (FACE_FROM_ID):
18879 * keyboard.c (read_char): Use UNSIGNED_CMP.
18881 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18882 not to EMACS_INT, to avoid GCC warning.
18884 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18886 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18887 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18888 isn't needed on 32-bit machines.
18890 * buffer.c (Fgenerate_new_buffer_name):
18891 Use EMACS_INT for count, not int.
18892 (advance_to_char_boundary): Return EMACS_INT, not int.
18894 * data.c (Qcompiled_function): Now static.
18896 * window.c (window_body_lines): Now static.
18898 * image.c (gif_load): Rename local to avoid shadowing.
18900 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18901 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18902 * alloc.c (make_save_value): Integer argument is now of type
18903 ptrdiff_t, not int.
18904 (mark_object): Use ptrdiff_t, not int.
18905 * lisp.h (pD): New macro.
18906 * print.c (print_object): Use it.
18908 * alloc.c: Use EMACS_INT, not int, to count objects.
18909 (total_conses, total_markers, total_symbols, total_vector_size)
18910 (total_free_conses, total_free_markers, total_free_symbols)
18911 (total_free_floats, total_floats, total_free_intervals)
18912 (total_intervals, total_strings, total_free_strings):
18913 Now EMACS_INT, not int. All uses changed.
18914 (Fgarbage_collect): Compute overall total using a double, so that
18915 integer overflow is less likely to be a problem. Check for overflow
18916 when converting back to an integer.
18917 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18918 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18919 These were 'int' variables that could overflow on 64-bit hosts;
18920 they were never used, so remove them instead of repairing them.
18921 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18922 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18923 Previously, this ceilinged at INT_MAX, but that doesn't work on
18925 (allocate_pseudovector): Don't use EMACS_INT when int would do.
18927 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
18928 (allocate_vectorlike): Check for ptrdiff_t overflow.
18929 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
18930 when a (possibly-narrower) signed value would do just as well.
18931 We prefer using signed arithmetic, to avoid comparison confusion.
18933 * alloc.c: Catch some string size overflows that we were missing.
18934 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
18935 for convenience in STRING_BYTES_MAX.
18936 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
18937 The definition here is exact; the one in lisp.h was approximate.
18938 (allocate_string_data): Check for string overflow. This catches
18939 some instances we weren't catching before. Also, it catches
18940 size_t overflow on (unusual) hosts where SIZE_MAX <= min
18941 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
18942 and ptrdiff_t and EMACS_INT are both 64 bits.
18944 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
18945 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
18946 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
18948 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
18950 * alloc.c (Fmake_string): Check for out-of-range init.
18952 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
18954 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
18956 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
18958 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
18959 xg_get_default_scrollbar_width.
18961 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
18962 (int_gtk_range_get_value): Move to the scroll bar part of the file.
18963 (style_changed_cb): Call update_theme_scrollbar_width and call
18964 x_set_scroll_bar_default_width and xg_frame_set_char_size for
18965 all frames (Bug#8505).
18966 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
18967 Call gtk_window_set_resizable if HAVE_GTK3.
18968 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
18969 and height if HAVE_GTK3 (Bug#8505).
18970 (scroll_bar_width_for_theme): New variable.
18971 (update_theme_scrollbar_width): New function.
18972 (xg_get_default_scrollbar_width): Move code to
18973 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
18974 (xg_initialize): Call update_theme_scrollbar_width.
18976 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
18978 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
18980 2011-06-12 Martin Rudalics <rudalics@gmx.at>
18982 * frame.c (make_frame): Call other_buffer_safely instead of
18985 * window.c (temp_output_buffer_show): Call display_buffer with
18986 second argument Vtemp_buffer_show_specifiers and reset latter
18987 immediately after the call.
18988 (Vtemp_buffer_show_specifiers): New variable.
18989 (auto_window_vscroll_p, next_screen_context_lines)
18990 (Vscroll_preserve_screen_position): Remove leading asterisks from
18993 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
18995 Fix minor problems found by GCC 4.6.0 static checking.
18996 * buffer.c (Qclone_number): Remove for now, as it's unused.
18997 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
18998 (record_buffer): Remove unused local.
18999 * frame.c (other_visible_frames, frame_buffer_list): Now static.
19000 (set_frame_buffer_list): Remove; unused.
19001 * frame.h (other_visible_frames): Remove decl.
19002 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
19003 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
19004 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
19006 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
19007 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
19008 Define only if HAVE_GPM.
19009 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
19010 (update_hints_inhibit): Remove; never set. All uses removed.
19011 * widgetprv.h (emacsFrameClassRec): Remove decl.
19012 * window.c (delete_deletable_window): Now returns void, since it
19013 wasn't returning anything.
19014 (compare_window_configurations): Remove unused locals.
19015 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
19016 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
19017 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
19018 the same widths as pointers. This follows up on the 2011-05-06 patch.
19019 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
19020 * xterm.h: Likewise.
19021 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
19023 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
19025 * makefile.w32-in: Update dependencies.
19026 (LISP_H): Add lib/intprops.h.
19028 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
19030 * image.c (gif_load): Add animation frame delay to the metadata.
19031 (syms_of_image): Use DEFSYM. New symbol `delay'.
19033 2011-06-11 Martin Rudalics <rudalics@gmx.at>
19035 * window.c (delete_deletable_window): Re-add.
19036 (Fset_window_configuration): Rewrite to handle dead buffers and
19037 consequently deletable windows.
19038 (window_tree, Fwindow_tree): Remove. Supply functionality in
19040 (compare_window_configurations): Simplify code.
19042 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
19044 * image.c (imagemagick_load_image): Fix type mismatch.
19045 (Fimagemagick_types): Likewise.
19047 * window.h (replace_buffer_in_windows): Declare.
19049 2011-06-11 Martin Rudalics <rudalics@gmx.at>
19051 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
19052 Qclone_number. Remove external declaration of Qdelete_window.
19053 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
19055 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
19056 Run Qbuffer_list_update_hook if allowed.
19057 (Fother_buffer): Rewrite doc-string. Major rewrite for new
19058 buffer list implementation.
19059 (other_buffer_safely): New function.
19060 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
19061 calls to replace_buffer_in_windows and
19062 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
19064 (record_buffer): Inhibit quitting and rewrite using quittable
19065 functions. Run Qbuffer_list_update_hook if allowed.
19066 (Frecord_buffer, Funrecord_buffer): New functions.
19067 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
19068 Move switch-to-buffer to window.el.
19069 (bury-buffer): Move to window.el.
19070 (Vbuffer_list_update_hook): New variable.
19072 * lisp.h (other_buffer_safely): Add prototype in buffer.c
19075 * window.h (resize_frame_windows): Move up in code.
19076 (Fwindow_frame): Remove EXFUN.
19077 (replace_buffer_in_all_windows): Remove prototype.
19078 (replace_buffer_in_windows_safely): Add prototype.
19080 * window.c: Declare Qdelete_window static again. Move down
19081 declaration of select_count.
19082 (Fnext_window, Fprevious_window): Rewrite doc-strings.
19083 (Fother_window): Move to window.el.
19084 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
19085 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
19086 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
19088 (replace_buffer_in_windows): Implement by calling
19089 Qreplace_buffer_in_windows.
19090 (replace_buffer_in_all_windows): Remove with some functionality
19091 moved into replace_buffer_in_windows_safely.
19092 (replace_buffer_in_windows_safely): New function.
19093 (select_window_norecord, select_frame_norecord): Move in front
19094 of run_window_configuration_change_hook. Remove now obsolete
19096 (Fset_window_buffer): Rewrite doc-string.
19097 Call Qrecord_window_buffer.
19098 (keys_of_window): Move binding for other-window to window.el.
19100 2011-06-11 Chong Yidong <cyd@stupidchicken.com>

19546 (single_display_spec_string_p): Support property values that are
19547 lists with the argument STRING its top-level element.
19548 (display_prop_string_p): Fix the condition for processing a
19549 property that is a list to be consistent with handle_display_spec.
19550 (handle_display_spec): New function, refactored from the
19551 last portion of handle_display_prop.
19552 (compute_display_string_pos): Accept additional argument
19553 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19554 value of a `display' property is a "replacing spec".
19555 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19556 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19557 the display property, but just return a value indicating whether
19558 the display property will replace the characters it covers.
19559 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19560 frame_window_p members of struct bidi_it.
19561 (compute_display_string_pos, compute_display_string_end):
19563 (push_it): Accept second argument POSITION, where pop_it should
19564 jump to continue iteration.
19565 (reseat_1): Initialize bidi_it.disp_pos.
19567 * keyboard.c (adjust_point_for_property): Adjust the call to
19568 display_prop_intangible_p to its new signature.

19573 (compute_display_string_pos, compute_display_string_end):
19574 Declare prototypes.
19575 (struct bidi_it): New members nchars and disp_pos. ch_len is now
19578 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
19580 Malloc failure behavior now depends on size of allocation.
19581 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19582 * lisp.h: Change signatures accordingly.
19583 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19584 All callers changed. (Bug#8762)
19586 * gnutls.c: Use Emacs's memory allocators.
19587 Without this change, the gnutls library would invoke malloc etc.
19588 directly, which causes problems on non-SYNC_INPUT hosts, and which
19589 runs afoul of improving memory_full behavior. (Bug#8761)
19590 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19591 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19592 xfree instead of the default malloc, realloc, free.
19593 (Fgnutls_boot): No need to check for memory allocation failure,
19594 since xmalloc does that for us.
19596 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19597 * category.c (hash_get_category_set):
19598 * ccl.c (ccl_driver):
19599 * charset.c (Fdefine_charset_internal):

19610 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
19611 (Fsxhash, Fgethash, Fputhash, Fmaphash):
19612 * image.c (make_image, search_image_cache, lookup_image)
19613 (xpm_put_color_table_h):
19614 * lisp.h (struct Lisp_Hash_Table):
19615 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19616 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19617 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19618 * alloc.c (allocate_vectorlike):
19619 Check for overflow in vector size calculations.
19620 * ccl.c (ccl_driver):
19621 Check for overflow when converting EMACS_INT to int.
19622 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19623 need to be updated by these changes.
19624 * fns.c (make_hash_table, maybe_resize_hash_table):
19625 Check for integer overflow with large hash tables.
19626 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19627 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19628 (SXHASH_REDUCE): New macro.
19629 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19630 Use it instead of discarding useful hash info with large hash values.
19631 (sxhash_float): New function.
19632 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19633 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19634 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19635 Rewrite to use FIXNUM_BITS, as this simplifies things.
19636 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19637 Adjust signatures to match updated version of code.
19638 (consing_since_gc): Now EMACS_INT, since a single hash table can
19639 use more than INT_MAX bytes.
19641 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19643 Make it possible to build with GCC-4.6+ -O2 -flto.
19645 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19647 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19649 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19650 Call minibuffer-inactive-mode.
19652 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19654 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19655 Update dependencies.
19657 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19659 * data.c (init_data): Remove code for UTS, this system is not
19662 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19664 Don't force ./temacs to start in terminal mode.
19666 * frame.c (make_initial_frame): Initialize faces in all cases, not
19667 only when CANNOT_DUMP is defined.
19668 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19670 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19672 * dispnew.c (add_window_display_history): Use const for the string
19673 pointer. Remove declaration, not needed.
19675 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19677 Use 'inline', not 'INLINE'.
19678 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19679 * alloc.c, fontset.c (INLINE): Remove.
19680 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19681 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19682 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19683 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19684 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19686 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19688 Make it possible to run ./temacs.
19690 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19691 syms_of_callproc does the same thing. Remove test for
19692 "initialized", do it in the caller.
19693 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19695 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19697 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19698 (read_minibuf): Use get_minibuffer.
19699 (syms_of_minibuf): Use DEFSYM.
19700 (Qmetadata): New var.
19701 * data.c (Qbuffer): Don't make it static.
19702 (syms_of_data): Use DEFSYM.
19704 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19706 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19707 (CCL_CODE_MIN): New macro.
19709 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19711 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19713 * eval.c (Qdebug): Now static.
19714 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19715 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19716 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19718 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19720 * image.c: Various fixes to ImageMagick code comments.
19721 (Fimagemagick_types): Doc fix.
19723 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19725 Minor fixes prompted by GCC 4.6.0 warnings.
19727 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19729 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19730 (x_clipboard_manager_save_all): Move extern decl to ...
19731 * xterm.h: ... here, so that it can be checked for consistency.
19733 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19735 * xselect.c (x_clipboard_manager_save_frame)
19736 (x_clipboard_manager_save_all): New functions.
19737 (Fx_clipboard_manager_save): Lisp function deleted.
19739 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19740 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19742 * xterm.h: Update prototype.
19744 2011-05-28 William Xu <william.xwl@gmail.com>
19746 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19747 exiting (Bug#8239).
19749 2011-05-28 Jim Meyering <meyering@redhat.com>
19751 Avoid a sign-extension bug in crypto_hash_function.
19752 * fns.c (to_uchar): Define.
19753 (crypto_hash_function): Use it to convert some newly-signed
19754 variables to unsigned, to avoid sign-extension bugs. For example,
19755 without this change, (md5 "truc") would evaluate to
19756 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19757 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19758 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19760 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19762 Integer overflow fixes.
19764 * dbusbind.c: Serial number integer overflow fixes.
19765 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19766 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19767 to hold a serial number that is too large for a fixnum.
19768 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19769 Check for serial numbers out of range. Decode any serial number
19770 that was so large that it became a float. (Bug#8722)
19772 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19773 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19774 Use XFASTINT rather than XUINT when numbers are nonnegative.
19775 (xd_append_arg, Fdbus_method_return_internal):
19776 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19777 arguments, check that Lisp number is nonnegative, rather than
19778 silently wrapping negative numbers around. (Bug#8722)
19779 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19782 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19784 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19786 ccl: Add integer overflow checks.
19787 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19788 (IN_INT_RANGE): New macros.
19789 (ccl_driver): Use them to check for integer overflow when
19790 decoding a CCL program. Many of the new checks are whether XINT (x)
19791 fits in int; it doesn't always, on 64-bit hosts. The new version
19792 doesn't catch all possible integer overflows, but it's an
19793 improvement. (Bug#8719)
19795 * alloc.c (make_event_array): Use XINT, not XUINT.
19796 There's no need for unsigned here.
19798 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19799 This follows up to the 2011-05-06 change that substituted uintptr_t
19800 for EMACS_INT. This case wasn't caught back then.
19802 Rework Fformat to avoid integer overflow issues.
19803 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19804 now (part of C89). Include <verify.h>.
19805 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19806 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19807 (Fformat): Avoid the prepass trying to compute sizes; it was only
19808 approximate and thus did not catch overflow reliably. Instead, walk
19809 through the format just once, formatting and computing sizes as we go,
19810 checking for integer overflow at every step, and allocating a larger
19811 buffer as needed. Keep track separately whether the format is
19812 multibyte. Keep only the most-recently calculated precision, rather
19813 than them all. Record whether each argument has been converted to
19814 string. Use EMACS_INT, not int, for byte and char and arg counts.
19815 Support field widths and precisions larger than INT_MAX. Avoid
19816 sprintf's undefined behavior with conversion specifications such as %#d
19817 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19818 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19819 formatting out-of-range floating point numbers with int
19820 formats. (Bug#8668)
19822 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19824 * data.c: Avoid integer truncation in expressions involving floats.
19825 * data.c: Include <intprops.h>.
19826 (arith_driver): When there's an integer overflow in an expression
19827 involving floating point, convert the integers to floating point
19828 so that the resulting value does not suffer from catastrophic
19829 integer truncation. For example, on a 64-bit host (* 4
19830 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19831 Do not rely on undefined behavior after integer overflow.
19833 merge count_size_as_multibyte, parse_str_to_multibyte
19834 * character.c, character.h (count_size_as_multibyte):
19835 Rename from parse_str_to_multibyte; all uses changed.
19836 Check for integer overflow.
19837 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19838 since it's now a duplicate of the other. This is more of
19839 a character than a buffer op, so better that it's in character.c.
19840 * fns.c, print.c: Adjust to above changes.
19842 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19844 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19846 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19848 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19849 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19850 (x_clipboard_manager_save): Now static.
19851 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19853 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19854 (crypto_hash_function): Now static.
19855 Fix pointer signedness problems. Avoid unnecessary initializations.
19857 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19859 * termhooks.h (Vselection_alist): Make it terminal-local.
19861 * terminal.c (create_terminal): Initialize it.
19863 * xselect.c: Support for clipboard managers.
19864 (Vselection_alist): Move to termhooks.h as terminal-local var.
19865 (LOCAL_SELECTION): New macro.
19866 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19867 (symbol_to_x_atom): Remove gratuitous arg.
19868 (x_handle_selection_request, lisp_data_to_selection_data)
19869 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19870 (x_own_selection, x_get_local_selection, x_convert_selection):
19871 New arg, specifying work frame. Use terminal-local Vselection_alist.
19872 (some_frame_on_display): Delete unused function.
19873 (Fx_own_selection_internal, Fx_get_selection_internal)
19874 (Fx_disown_selection_internal, Fx_selection_owner_p)
19875 (Fx_selection_exists_p): New optional frame arg.
19876 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19877 (x_handle_selection_clear): Don't treat other terminals with the
19878 same keyboard specially. Use the terminal-local Vselection_alist.
19879 (x_clear_frame_selections): Use Frun_hook_with_args.
19881 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19883 * xterm.h: Add support for those atoms.
19885 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19887 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19888 (converted_selections, conversion_fail_tag): New global variables.
19889 (x_selection_request_lisp_error): Free the above.
19890 (x_get_local_selection): Remove unnecessary code.
19891 (x_reply_selection_request): Args changed; handle arbitrary array
19892 of converted selections stored in converted_selections.
19893 Separate the XChangeProperty and SelectionNotify steps.
19894 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19895 (x_convert_selection): New function.
19896 (x_handle_selection_event): Simplify.
19897 (x_get_foreign_selection): Don't ignore incoming requests while
19898 waiting for an answer; this will fail when we implement
19899 SAVE_TARGETS, and seems unnecessary anyway.
19900 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19901 (Vx_sent_selection_functions): Doc fix.
19903 2011-05-26 Leo Liu <sdl.web@gmail.com>
19905 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19907 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19909 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19911 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19912 for fringe update if it has periodic bitmap.
19913 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19914 and fringe_bitmap_periodic_p.
19916 * fringe.c (get_fringe_bitmap_data): New function.
19917 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19918 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19919 row. Mark glyph row for fringe update if periodicity changed.
19921 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19922 for fringe update unless it has periodic bitmap.
19924 2011-05-25 Kenichi Handa <handa@m17n.org>

19941 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19942 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19943 Remove macros that are defined and never used.
19944 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19946 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19948 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19949 (Fx_get_selection_internal): Minor cleanup.

19979 * systime.h (Time): Define only if emacs is defined.
19980 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19981 where the include path doesn't have X11/X.h by default. See
19982 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19984 2011-05-20 Kenichi Handa <handa@m17n.org>
19986 * composite.c (find_automatic_composition): Fix previous change.
19988 2011-05-20 Glenn Morris <rgm@gnu.org>
19990 * lisp.mk: New file, split from Makefile.in.
19991 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19992 (shortlisp): Remove.
19993 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19995 2011-05-19 Glenn Morris <rgm@gnu.org>
19997 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19998 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19999 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20000 (lisp): Set the order to that of loadup.el.
20001 (shortlisp): Make it a copy of $lisp.
20002 (SOME_MACHINE_LISP): Remove.
20003 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20004 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20006 2011-05-18 Kenichi Handa <handa@m17n.org>
20008 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20009 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20010 (find_automatic_composition): Mostly rewrite for efficiency.
20012 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20014 * makefile.w32-in: Update dependencies.
20016 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20018 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20019 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20021 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20023 Fix some integer overflow issues, such as string length overflow.
20025 * insdel.c (count_size_as_multibyte): Check for string overflow.
20027 * character.c (lisp_string_width): Check for string overflow.
20028 Use EMACS_INT, not int, for string indexes and lengths; in
20029 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20030 the resulting string length overflows an EMACS_INT; instead,
20031 report a string overflow if no precision given. When checking for
20032 precision exhaustion, use a check that cannot possibly have
20033 integer overflow. (Bug#8675)
20034 * character.h (lisp_string_width): Adjust to new signature.
20036 * alloc.c (string_overflow): New function.
20037 (Fmake_string): Use it. This doesn't change behavior, but saves
20038 a few bytes and will simplify future changes.
20039 * character.c (string_escape_byte8): Likewise.
20040 * lisp.h (string_overflow): New decl.
20042 Fixups, following up to the user-interface timestamp change.
20043 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20044 for UI timestamps, instead of unsigned long.
20045 * msdos.c (mouse_get_pos): Likewise.
20046 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20047 * w32gui.h (Time): Define by including "systime.h" rather than by
20048 declaring it ourselves. (Bug#8664)
20050 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20051 * image.c (clear_image_cache): Likewise.
20053 * term.c (term_mouse_position): Don't assume time_t wraparound.
20055 Be more systematic about user-interface timestamps.
20056 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20057 and sometimes 'EMACS_UINT', to represent these timestamps.
20058 This change causes it to use 'Time' uniformly, as that's what X uses.
20059 This makes the code easier to follow, and makes it easier to catch
20060 integer overflow bugs such as Bug#8664.
20061 * frame.c (Fmouse_position, Fmouse_pixel_position):
20062 Use Time, not unsigned long, for user-interface timestamps.
20063 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20064 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20065 * keyboard.h (last_event_timestamp): Likewise.
20066 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20067 * menu.h (xmenu_show): Likewise.
20068 * term.c (term_mouse_position): Likewise.
20069 * termhooks.h (struct input_event.timestamp): Likewise.
20070 (struct terminal.mouse_position_hook): Likewise.
20071 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20072 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20073 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20074 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20075 what it was before.
20076 * menu.h, termhooks.h: Include "systime.h", for Time.
20078 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20079 Don't assume that the difference between two unsigned long values
20080 can fit into an integer. At this point, we know button_down_time
20081 <= event->timestamp, so the difference must be nonnegative, so
20082 there's no need to cast the result if double-click-time is
20083 nonnegative, as it should be; check that it's nonnegative, just in
20084 case. This bug is triggered when events are more than 2**31 ms
20085 apart (about 25 days). (Bug#8664)
20087 * xselect.c (last_event_timestamp): Remove duplicate decl.
20088 (x_own_selection): Remove needless cast to unsigned long.
20090 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20091 that always fit in int. Use a sentinel instead of a counter, to
20092 avoid a temp and to allay GCC's concerns about possible int overflow.
20093 * frame.h (struct frame): Use int for menu_bar_items_used
20094 instead of EMACS_INT, since it always fits in int.
20096 * menu.c (grow_menu_items): Check for int overflow.
20098 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20100 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20101 Before, the code was not consistent. These values cannot exceed
20102 2**31 - 1 so there's no need to make them unsigned.
20103 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20104 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20105 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20107 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20109 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20110 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20111 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20112 presumably because the widths might not match.
20114 * window.c (size_window): Avoid needless test at loop start.
20116 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20118 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20120 2011-05-12 Drew Adams <drew.adams@oracle.com>
20122 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20124 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20126 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20127 `width' to `bar_area_x' and `bar_area_width', respectively.
20128 (x_scroll_run): Take account of fringe background extension.
20130 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20131 Rename local vars `left' and `width' to `bar_area_x' and
20132 `bar_area_width', respectively.
20133 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20134 background extension.
20136 2011-05-10 Jim Meyering <meyering@redhat.com>
20138 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20140 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20142 * image.c (Finit_image_library): Return t for built-in image types,
20143 like pbm and xbm. (Bug#8640)
20145 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20147 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20149 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20151 * w32console.c (Fset_screen_color): Doc fix.
20152 (Fget_screen_color): New function.
20153 (syms_of_ntterm): Defsubr it.
20155 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20156 unlink the temporary file if Fcall_process didn't create it in the
20158 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20159 child process will be redirected to a file specified with `:file'.
20160 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20161 cue to call_process_cleanup not to close that handle.
20163 2011-05-07 Ben Key <bkey76@gmail.com>
20165 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20166 one of two shell specific rules, either bootstrap-temacs-CMD or
20167 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20168 to the previous implementation of the bootstrap-temacs rule.
20169 The bootstrap-temacs-CMD rule is similar to the previous
20170 implementation of the bootstrap-temacs rule except that it
20171 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20174 These changes, along with some changes to nt/configure.bat,
20175 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20176 earlier fix to add support for --cflags and --ldflags options
20177 that include quotes so that it works whether make uses cmd or
20180 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20182 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20183 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20185 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20186 a string. Handle both cases.
20187 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20188 (Fdbus_register_method): Use Qinvalid_function.
20190 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20192 * makefile.w32-in: Update dependencies.
20193 (LISP_H): Add inttypes.h and stdin.h.
20194 (PROCESS_H): Add unistd.h.
20196 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20198 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20199 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20201 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20203 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20205 * term.c (vfatal): Remove stray call to va_end.
20206 It's not needed and the C Standard doesn't allow it here anyway.
20208 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20209 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20211 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20214 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20216 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20218 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20220 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20222 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20224 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20225 * charset.c (Fdefine_charset_internal): Don't initialize
20226 charset.code_space[15]. The value was garbage, on hosts with
20227 32-bit int (Bug#8600).
20229 * lread.c (read_integer): Be more consistent with string-to-number.
20230 Use string_to_number to do the actual conversion; this avoids
20231 rounding errors and fixes some other screwups. Without this fix,
20232 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20233 (digit_to_number): Move earlier, for benefit of read_integer.
20234 Return -1 if the digit is out of range for the base, -2 if it is
20235 not a digit in any supported base. (Bug#8602)
20237 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20239 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20240 to match comment at start of function. This also removes a
20241 GCC warning about overflow in a 32+64-bit port.
20243 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20245 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20246 Reported by Stefan Monnier in
20247 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20248 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20249 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20251 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20252 (EMACS_UINTPTR): Likewise, with uintptr_t.
20254 * lisp.h: Prefer 64-bit EMACS_INT if available.
20255 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20256 on 32-bit hosts that have 64-bit int, so that they can access
20258 However, temporarily disable this change unless the temporary
20259 symbol WIDE_EMACS_INT is defined.
20261 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20263 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20264 This removes an assumption that EMACS_INT and long are the same
20265 width as pointers. The assumption is true for Emacs porting targets
20266 now, but we want to make other targets possible.
20267 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20268 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20269 In the rest of the code, change types of integers that hold casted
20270 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20271 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20272 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20273 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20274 No need to cast type when ORing.
20275 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20276 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20277 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20278 assume EMACS_INT is the same width as char *.
20279 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20280 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20281 Remove no-longer-needed casts.
20282 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20283 (xg_tool_bar_help_callback, xg_make_tool_item):
20284 Use EMACS_INTPTR to hold an integer
20285 that will be cast to void *; this can avoid a GCC warning
20286 if EMACS_INT is not the same width as void *.
20287 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20288 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20289 (current_message_1, set_message_1):
20290 Use a local to convert to proper width without a cast.
20291 * xmenu.c (dialog_selection_callback): Likewise.
20293 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20294 Also, don't assume VALBITS / RAND_BITS is less than 5,
20295 and don't rely on undefined behavior when shifting a 1 left into
20297 * lisp.h (get_random): Change signature to match.
20299 * lread.c (hash_string): Use size_t, not int, for hash computation.
20300 Normally we prefer signed values; but hashing is special, because
20301 it's better to use unsigned division on hash table sizes so that
20302 the remainder is nonnegative. Also, size_t is the natural width
20303 for hashing into memory. The previous code used 'int', which doesn't
20304 retain enough info to hash well into very large tables.
20305 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20307 * dbusbind.c: Don't possibly lose pointer info when converting.
20308 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20309 Use XPNTR rather than XHASH, so that the high-order bits of
20310 the pointer aren't lost when converting through void *.
20312 * eval.c (Fautoload): Don't double-shift a pointer.
20314 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20316 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20318 * gnutls.c (DEF_GNUTLS_FN):
20319 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20321 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20323 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20326 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20328 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20329 New version that can reserve upto 2GB of heap space.
20331 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20333 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20335 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20337 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20338 `gnutls_certificate_set_x509_key_file'.
20340 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20342 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20343 Update dependencies.
20345 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20347 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20348 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20349 Remove unused parameter `fildes'.
20350 * process.c (read_process_output, send_process): Don't pass it.
20352 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20354 Fix previous change: the library cache is defined in w32.c.
20355 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20356 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20358 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20360 Implement dynamic loading of GnuTLS on Windows.
20362 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20363 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20364 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20367 * gnutls.c (Qgnutls_dll): Define.
20368 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
20369 (gnutls_*): Declare function pointers.
20370 (init_gnutls_functions): New function to initialize function pointers.
20371 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
20372 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
20373 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20374 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
20375 (emacs_gnutls_write, emacs_gnutls_read)
20376 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20377 (Fgnutls_available_p): New function.
20378 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
20379 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
20380 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
20382 * image.c: Include w32.h.
20383 (Vimage_type_cache): Delete.
20384 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
20385 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
20386 (w32_delayed_load): Move to w32.c.
20388 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20390 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20391 (w32_delayed_load): Move from image.c. When loading a library, record
20392 its filename in the :loaded-from property of the library id.
20393 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20394 Initialize and staticpro them.
20395 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20397 * process.c: Include lisp.h before w32.h, not after.
20398 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20399 instead of gnutls_record_check_pending.
20401 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20403 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20405 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20406 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20409 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20411 * xterm.c (x_set_frame_alpha): Do not set property on anything

20435 (wait_for_termination, interruptible_wait_for_termination):
20436 Move after wait_for_termination_1.

20451 rather than `XVECTOR (FOO)->size'.
20453 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20454 inttypes.h, as a gnulib replacement is used if it not available in
20457 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20459 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

20467 space for up to 2 characters produced in a loop.
20468 (decode_coding_iso_2022): Abort if there isn't enough place in
20469 charbuf for the composition carryover bytes.
20471 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20473 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
20474 aborting when %lld or %lll format is passed.
20475 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20476 %llo or %llx format is passed. (Bug#8545)
20478 * window.c (window_scroll_line_based): Use a marker instead of
20479 simple variables to record original value of point. (Bug#7952)
20481 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20482 produced by %s or %c overflows available buffer space. (Bug#8545)
20484 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20486 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20487 (SIZE_MAX): Move defn after all includes, as they might #define it.
20489 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20491 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20493 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20495 * keyboard.c (Qdelayed_warnings_hook): Define.
20496 (command_loop_1): Run `delayed-warnings-hook'
20497 if Vdelayed_warnings_list is non-nil.
20498 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20499 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20501 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20503 * doprnt.c (doprnt): Don't return value smaller than the buffer
20504 size if the message was truncated. (Bug#8545).
20506 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20508 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20509 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20511 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20513 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20515 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20517 * makefile.w32-in: Update dependencies.
20519 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20521 Improve `doprnt' and its usage. (Bug#8545)
20522 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20523 `format_end'. Remove support for %l as a conversion specifier.
20524 Don't use xrealloc. Improve diagnostics when the %l size modifier
20525 is used. Update the commentary.
20527 * eval.c (verror): Simplify calculation of size_t.
20529 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20532 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20534 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20537 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20539 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20540 This makes this file independent of the recent pseudovector change.
20542 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20544 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20546 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20547 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20548 Remove unused local.
20549 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20551 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20552 GCC 4.6.0 optimizes based on type-based alias analysis.
20553 For example, if b is of type struct buffer * and v of type struct
20554 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20555 != &v->size, and therefore "v->size = 1; b->size = 2; return
20556 v->size;" must therefore return 1. This assumption is incorrect
20557 for Emacs, since it type-puns struct Lisp_Vector * with many other
20558 types. To fix this problem, this patch adds a new type struct
20559 vectorlike_header that documents the constraints on layout of vectors
20560 and pseudovectors, and helps optimizing compilers not get fooled
20561 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20562 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20563 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20565 (XSETPVECTYPE): Rewrite in terms of new macro.
20566 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20567 This is a bit clearer, and further avoids the possibility of
20568 undesirable aliasing.
20569 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20570 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20571 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20572 since Lisp_Subr is a special case (no "next" field).
20573 (ASIZE): Now uses header.size rather than size.
20574 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20575 to avoid the hassle of writing XVECTOR (foo)->header.size.
20576 (struct vectorlike_header): New type.
20577 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20578 object, to help avoid aliasing.
20579 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20580 (SUBRP): Likewise, since Lisp_Subr is a special case.
20581 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20582 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20583 (struct Lisp_Hash_Table): Combine first two members into a single
20584 struct vectorlike_header member. All uses of "size" and "next" members
20585 changed to be "header.size" and "header.next".
20586 * buffer.h (struct buffer): Likewise.
20587 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20588 * frame.h (struct frame): Likewise.
20589 * process.h (struct Lisp_Process): Likewise.
20590 * termhooks.h (struct terminal): Likewise.
20591 * window.c (struct save_window_data, struct saved_window): Likewise.
20592 * window.h (struct window): Likewise.
20593 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20594 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20595 * buffer.c (init_buffer_once): Likewise.
20596 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20598 * process.c (Fformat_network_address): Use local var for size,
20601 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20603 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20604 * data.c (atof): Remove decl; no longer used or needed.
20605 (digit_to_number): Move to lread.c.
20606 (Fstring_to_number): Use new string_to_number function, to be
20607 consistent with how the Lisp reader treats infinities and NaNs.
20608 Do not assume that floating-point numbers represent EMACS_INT
20609 without losing information; this is not true on most 64-bit hosts.
20610 Avoid double-rounding errors, by insisting on integers when
20611 parsing non-base-10 numbers, as the documentation specifies.
20612 * lisp.h (string_to_number): New decl, replacing ...
20613 (isfloat_string): Remove.
20614 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20615 (read1): Do not accept +. and -. as integers; this
20616 appears to have been a coding error. Similarly, do not accept
20617 strings like +-1e0 as floating point numbers. Do not report
20618 overflow for integer overflows unless the base is not 10 which
20619 means we have no simple and reliable way to continue.
20620 Break out the floating-point parsing into a new
20621 function string_to_number, so that Fstring_to_number parses
20622 floating point numbers consistently with the Lisp reader.
20623 (digit_to_number): Move here from data.c. Make it static inline.
20624 (E_CHAR, EXP_INT): Remove, replacing with ...
20625 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20626 (string_to_number): New function, replacing isfloat_string.
20627 This function checks for valid syntax and produces the resulting
20628 Lisp float number too. Rework it so that string-to-number
20629 no longer mishandles examples like "1.0e+". Use strtoumax,
20630 so that overflow for non-base-10 numbers is reported only when
20631 there's no portable and simple way to convert to floating point.
20633 * textprop.c (set_text_properties_1): Rewrite for clarity,
20634 and to avoid GCC warning about integer overflow.
20636 * intervals.h (struct interval): Use EMACS_INT for members
20637 where EMACS_UINT might cause problems. See
20638 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20639 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20640 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20642 (offset_intervals): Tell GCC not to worry about length overflow
20643 when negating a negative length.
20645 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20646 (overrun_check_free): Likewise.
20648 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20649 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20652 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20653 (gnutls_make_error): Rename local to avoid shadowing.
20654 (gnutls_emacs_global_deinit): ifdef out; not used.
20655 (Fgnutls_boot): Use const for pointer to readonly storage.
20656 Comment out unused local. Fix pointer signedness problems.
20658 * lread.c (openp): Don't stuff size_t into an 'int'.
20659 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20660 about possible signed overflow.
20662 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20663 (GDK_KEY_g): Don't define if already defined.
20664 (xg_prepare_tooltip): Avoid pointer signedness problem.
20665 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20667 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20668 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20670 * xfns.c (Fx_window_property): Simplify a bit,
20671 to make a bit faster and to avoid GCC 4.6.0 warning.
20672 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20674 * fns.c (internal_equal): Don't assume size_t fits in int.
20676 * alloc.c (compact_small_strings): Tighten assertion a little.
20678 Replace pEd with more-general pI, and fix some printf arg casts.
20679 * lisp.h (pI): New macro, generalizing old pEd macro to other
20680 conversion specifiers. For example, use "...%"pI"d..." rather
20681 than "...%"pEd"...".
20682 (pEd): Remove. All uses replaced with similar uses of pI.
20683 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20684 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20685 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20686 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20687 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20688 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20689 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20691 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20692 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20693 * print.c (safe_debug_print, print_object): Likewise.
20694 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20696 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20697 avoiding the 0 flag, which is not portable.
20698 * process.c (Fmake_network_process): Use pI to avoid cast.
20699 * region-cache.c (pp_cache): Likewise.
20700 * xdisp.c (decode_mode_spec): Likewise.
20701 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
20702 behavior on 64-bit hosts with printf arg.
20703 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20704 (x_stop_queuing_selection_requests): Likewise.
20705 (x_get_window_property): Don't truncate byte count to an 'int'
20708 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20709 here, since it parses constructs like leading '-' and spaces,
20710 which are not wanted; and it overflows with large numbers.
20711 Instead, simply match F[0-9]+, which is what is wanted anyway.
20713 * alloc.c: Remove unportable assumptions about struct layout.
20714 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20715 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20716 (allocate_vectorlike, make_pure_vector): Use the new macros,
20717 plus offsetof, to remove unportable assumptions about struct layout.
20718 These assumptions hold on all porting targets that I know of, but
20719 they are not guaranteed, they're easy to remove, and removing them
20720 makes further changes easier.
20722 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20723 This doesn't fix a bug but makes the code clearer.
20724 (string_overrun_cookie): Now const. Use initializers that
20725 don't formally overflow signed char, to avoid warnings.
20726 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20727 can cause Emacs to crash when string overrun checking is enabled.
20728 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20729 multiple of sizeof (EMACS_INT); it need not be, if
20730 alignof(EMACS_INT) < sizeof (EMACS_INT).
20731 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20733 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

20737 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
20739 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
20740 supposed to be handshaking. (Bug#8556)
20741 Reported by Paul Eggert <eggert@cs.ucla.edu>.

20745 * lisp.h (Qdebug): List symbol.
20746 * eval.c (Qdebug): Restore global linkage.
20747 * keyboard.c (debug-on-event): New variable.
20748 (handle_user_signal): Break into debugger when debug-on-event
20749 matches the current signal symbol.
20751 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
20753 * alloc.c (check_sblock, check_string_bytes)
20754 (check_string_free_list): Convert to standard C.
20756 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
20758 * w32.c (emacs_gnutls_push): Fix typo.
20760 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20762 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20763 "cast to pointer from integer of different size".
20765 Improve doprnt and its use in verror. (Bug#8545)
20766 * doprnt.c (doprnt): Document the set of format control sequences
20767 supported by the function. Use SAFE_ALLOCA instead of always
20770 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20771 is one byte too soon. Don't use xrealloc; instead xfree and
20774 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20776 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
20779 * gnutls.c: Renamed global_initialized to
20780 gnutls_global_initialized. Added internals for the
20781 :verify-hostname-error, :verify-error, and :verify-flags
20782 parameters of `gnutls-boot' and documented those parameters in the
20783 docstring. Start callback support.
20784 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20785 unless a fatal error occurred. Call gnutls_alert_send_appropriate
20786 on error. Return error code.
20787 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
20788 (emacs_gnutls_read): Likewise.
20789 (Fgnutls_boot): Return handshake error code.
20790 (emacs_gnutls_handle_error): New function.
20791 (wsaerror_to_errno): Likewise.
20793 * w32.h (emacs_gnutls_pull): Add prototype.
20794 (emacs_gnutls_push): Likewise.
20796 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
20797 (emacs_gnutls_push): Likewise.
20799 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
20801 * process.c (wait_reading_process_output): Check if GnuTLS
20802 buffered some data internally if no FDs are set for TLS
20805 * makefile.w32-in (OBJ2): Add gnutls.$(O).
20806 (LIBS): Link to USER_LIBS.
20807 ($(BLD)/gnutls.$(0)): New target.

20811 * xdisp.c (handle_single_display_spec): Rename the
20812 display_replaced_before_p argument into display_replaced_p, to
20813 make it consistent with the commentary. Fix typos in the
20816 * textprop.c (syms_of_textprop): Remove dead code.
20817 (copy_text_properties): Delete obsolete commentary about an
20818 interface that was deleted long ago. Fix typos in the description

20822 to changes in oldXMenu/XMenu.h from 2011-04-16.
20823 <menu_help_message, prev_menu_help_message>: Constify.
20824 (IT_menu_make_room): menu->help_text is now `const char **';

20900 FINAL_CHAR is a character, and use %c when it is passed as
20901 argument to `error'.
20903 2011-04-23 Eli Zaretskii <eliz@gnu.org>
20905 * s/ms-w32.h (localtime): Redirect to sys_localtime.

21091 ns_descriptor_to_entity that were caused by using free to
21092 deallocate memory blocks that were allocated by xmalloc (via

21113 (emacs_read, emacs_write): Use it.
21114 * process.c (send_process): Adjust to the new signatures of
21115 emacs_write and emacs_gnutls_write. Do not attempt to store

21308 * font.c (font_close_object): Now static.
21309 * font.h (font_close_object): Remove.
21310 * fontset.c (FONTSET_OBJLIST): Remove.
21311 (free_realized_fontset) #if-0 the body, which does nothing.
21312 (face_suitable_for_char_p): #if-0, as it's never called.
21313 * fontset.h (face_suitable_for_char_p): Remove decl.
21314 * xfaces.c (face_at_string_position):
21315 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
21316 since 0 is always ASCII.
21318 * fns.c (weak_hash_tables): Now static.
21320 * fileio.c: Make symbols static if they're not exported.

21339 * editfns.c, lisp.h (get_operating_system_release): Remove.
21340 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
21341 worth the hassle of breaking this out.
21343 * xterm.c: Make symbols static if they're not exported.
21344 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
21345 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

21447 * buffer.c (buffer_count): Remove unused var.

21456 * atimer.h (run_all_atimers): Remove; not exported.
21458 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
21459 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
21460 was inaccessible from Lisp.
21461 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
21462 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
21464 alloc.c: Import and export fewer symbols, and remove unused items.
21465 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
21467 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
21468 it's not optimized away by whole-program optimization.

21470 (catchlist, handlerlist, mark_backtrace):
21471 Declare only if BYTE_MARK_STACK.

21480 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
21481 (mark_backtrace): Define only if BYTE_MARK_STACK.
21482 * xdisp.c (message_enable_multibyte): Now static.
21484 Declare Lisp_Object Q* variables to be 'static' if not exported.
21485 This makes it easier for human readers (and static analyzers)
21486 to see whether these variables are used from other modules.
21487 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
21488 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

21497 Remove decls of unexported vars.
21498 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21500 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21502 Make Emacs functions such as Fatom 'static' by default.
21503 This makes it easier for human readers (and static analyzers)
21504 to see whether these functions can be called from other modules.
21505 DEFUN now defines a static function. To make the function external
21506 so that it can be used in other C modules, use the new macro DEFUE.
21507 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21508 (Finit_image_library):
21509 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21510 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21511 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21512 Remove decls, since these functions are now static.
21513 (Funintern, Fget_internal_run_time): New decls, since these functions
21514 were already external.
21516 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21517 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

21523 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21524 Mark functions with DEFUE instead of DEFUN,
21525 if they are used in other modules.
21526 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21527 decls for now-static functions.
21528 * buffer.h (Fdelete_overlay): Remove decl.
21529 * callproc.c (Fgetenv_internal): Mark as internal.

21538 * image.c (Finit_image_library): New forward static decl.
21539 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21540 * intervals.h (Fprevious_property_change):
21541 (Fremove_list_of_text_properties): Remove decls.
21542 * keyboard.c (Fthis_command_keys): Remove decl.
21543 (Fcommand_execute): New forward static decl.

21559 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
21561 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21564 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21566 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21567 when at ZV. (Bug#8487)
21569 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21571 * charset.c (Fclear_charset_maps): Use xfree instead of free.

21574 * sound.c (sound_cleanup, alsa_close): Likewise.
21575 * termcap.c (tgetent): Likewise.

21577 * xsettings.c (read_and_apply_settings): Likewise.
21579 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21580 (overrun_check_free): Protoize.
21582 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21584 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21585 since callers should never pass a negative size.
21586 Change the signature to match that of plain 'read' and 'write'; see
21587 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21588 * lisp.h: Update prototypes of emacs_write and emacs_read.
21590 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21592 * xdisp.c (redisplay_window): Don't try to determine the character
21593 position of the scroll margin if the window start point w->startp
21594 is outside the buffer's accessible region. (Bug#8468)
21596 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21598 Fix write-region and its subroutines for buffers > 2GB.
21599 * fileio.c (a_write, e_write): Modify declaration of arguments and
21600 local variables to support buffers larger than 2GB.
21601 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21603 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21604 argument, local variables, and return value.
21606 * lisp.h: Update prototypes of emacs_write and emacs_read.
21608 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21610 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21612 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21614 Fix more problems found by GCC 4.6.0's static checks.
21616 * xdisp.c (vmessage): Use a better test for character truncation.
21618 * charset.c (load_charset_map): <, not <=, for optimization,
21619 and to avoid potential problems with integer overflow.
21620 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21621 * casetab.c (set_identity, shuffle): Likewise.
21622 * editfns.c (Fformat): Likewise.
21623 * syntax.c (skip_chars): Likewise.
21625 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21626 This also lets GCC 4.6.0 generate slightly better loop code.
21628 * callint.c (Fcall_interactively): <, not <=, for optimization.
21629 (Fcall_interactively): Count the number of arguments produced,
21630 not the number of arguments given. This is simpler and lets GCC
21631 4.6.0 generate slightly better code.
21633 * ftfont.c: Distingish more carefully between FcChar8 and char.
21634 The previous code passed unsigned char * to a functions like
21635 strlen and xstrcasecmp that expect char *, which does not
21636 conform to the C standard.
21637 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21638 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21639 char * when the C standard requires it.
21641 * keyboard.c (read_char): Remove unused var.
21643 * eval.c: Port to Windows vsnprintf (Bug#8435).
21644 Include <limits.h>.
21645 (SIZE_MAX): Define if the headers do not.
21646 (verror): Do not give up if vsnprintf returns a negative count.
21647 Instead, grow the buffer. This ports to Windows vsnprintf, which
21648 does not conform to C99. Problem reported by Eli Zaretskii.
21649 Also, simplify the allocation scheme, by avoiding the need for
21650 calling realloc, and removing the ALLOCATED variable.
21652 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21654 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21655 But keep the doprint source code for now, as we might revamp it
21656 and use it again (Bug#8435).
21657 * lisp.h (doprnt): Remove.
21658 * Makefile.in (base_obj): Remove doprnt.o.
21659 * deps.mk (doprnt.o): Remove.
21661 error: Print 32- and 64-bit integers portably (Bug#8435).
21662 Without this change, on typical 64-bit hosts error ("...%d...", N)
21663 was used to print both 32- and 64-bit integers N, which relied on
21664 undefined behavior.
21665 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21666 * lisp.h (error, verror): Mark as printf-like functions.
21667 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21668 Report overflow in size calculations when allocating printf buffer.
21669 Do not truncate output string at its first null byte.
21670 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21671 Truncate the output at a character boundary, since vsnprintf does not
21673 * charset.c (check_iso_charset_parameter): Convert internal
21674 character to string before calling 'error', since %c now has the
21676 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21677 overflow when computing char to be passed to 'error'. Do not
21678 pass Lisp_Object to 'error'; pass the integer instead.
21679 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21680 formatted with plain %d.
21682 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21684 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21686 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21688 * xterm.c (x_catch_errors): Remove duplicate declaration.
21690 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21692 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21694 2011-04-10 Jim Meyering <meyering@redhat.com>
21696 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21697 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21698 return ssize_t not "int", and use size_t as the buffer length.
21699 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21700 * gnutls.h: Update declarations.
21701 * process.c (read_process_output): Use ssize_t, to match.
21702 (send_process): Likewise.
21704 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21706 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21708 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21710 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):

21718 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21720 Fix some uses of `int' instead of EMACS_INT.
21721 * search.c (string_match_1, fast_string_match)
21722 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21723 (scan_buffer, find_next_newline_no_quit)

21774 instead of using internal_with_output_to_temp_buffer.
21775 (Qhelp_form_show): New var.
21776 (syms_of_keyboard): Use DEFSYM macro.
21778 * print.c (internal_with_output_to_temp_buffer): Function deleted.

21814 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21816 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21817 This avoids several warnings with gcc -Wstrict-overflow.
21818 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21819 directly, rather than having caller test rule sign. This avoids
21820 some unnecessary tests.
21821 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21822 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21823 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21825 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21826 (xfont_open): Avoid unnecessary tests.
21828 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21830 * composite.h, composite.c (composition_gstring_put_cache):
21831 Use EMACS_INT, not int, for length.
21833 * composite.h (COMPOSITION_DECODE_REFS): New macro,
21834 breaking out part of COMPOSITION_DECODE_RULE.
21835 (COMPOSITION_DECODE_RULE): Use it.
21836 * composite.c (get_composition_id): Remove unused local vars,
21837 by using the new macro.
21839 * textprop.c (set_text_properties_1): Change while to do-while,
21840 since the condition is always true at first.
21842 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21843 (interval_deletion_adjustment): Return unsigned value.
21846 * process.c (list_processes_1, create_pty, read_process_output):

21848 (create_pty): Remove unnecessary "volatile"s.
21849 (Fnetwork_interface_info): Avoid possibility of int overflow.

21862 * print.c (print_error_message): Avoid int overflow.
21864 * font.c (font_list_entities): Redo for clarity,
21865 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21867 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21868 (font_score): Avoid potential overflow in diff calculation.

21871 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21873 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21875 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21876 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21877 can always succeed if overflow has undefined behavior.
21879 * search.c (boyer_moore, wordify): Remove vars set but not used.
21880 (wordify): Omit three unnecessary tests.
21882 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

21891 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21892 (Finsert_file_contents): Remove unnecessary code checking fd.
21894 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21895 Check for integer overflow on size calculations.
21897 * buffer.c (Fprevious_overlay_change): Remove var that is set
21900 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21901 Remove vars that are set but not used.
21902 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21903 (timer_check_2): Mark vars as initialized.
21905 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21907 * image.c (lookup_image): Remove var that is set but not used.
21908 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21910 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21911 that are set but not used.
21913 * xfns.c (make_invisible_cursor): Don't return garbage
21914 if XCreateBitmapFromData fails (Bug#8410).
21916 * xselect.c (x_get_local_selection, x_handle_property_notify):
21917 Remove vars that are set but not used.
21919 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
21920 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
21922 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
21923 Remove var that is set but not used.
21924 (scroll_bar_windows_size): Now size_t, not int.
21925 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
21926 Check for overflow.
21928 * xfaces.c (realize_named_face): Remove vars that are set but not used.
21929 (map_tty_color) [!defined MSDOS]: Likewise.
21931 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21933 * coding.c: Remove vars that are set but not used.
21934 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21935 All callers changed.
21936 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21937 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21938 (decode_coding_charset): Remove vars that are set but not used.
21940 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21941 that is set but not used.
21943 * print.c (print_object): Remove var that is set but not used.
21945 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21946 The gnulib version avoids calling malloc in the usual case,
21947 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21948 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21949 * filelock.c (current_lock_owner): Likewise.
21950 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21951 * sysdep.c: Include allocator.h, careadlinkat.h.
21952 (emacs_no_realloc_allocator): New static constant.
21953 (emacs_readlink): New function.
21954 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21955 ../lib/careadlinkat.h.
21957 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21959 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21960 first non-nil return value).

21964 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21965 if not defined (Bug#8403).
21967 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21969 * xdisp.c (display_count_lines): Remove parameter `start',
21970 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21971 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21972 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21974 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21975 and thereabouts. All callers changed.
21976 (get_per_char_metric): Remove parameter `f', unused since
21977 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
21979 2011-04-02 Jim Meyering <meyering@redhat.com>
21981 do not dereference NULL upon failed strdup
21982 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21983 (ns_get_family): Likewise.
21985 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21987 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21989 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21991 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21994 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21996 Add lexical binding.
21998 * window.c (Ftemp_output_buffer_show): New fun.
21999 (Fsave_window_excursion):
22000 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
22002 * lread.c (lisp_file_lexically_bound_p): New function.
22003 (Fload): Bind Qlexical_binding.
22004 (readevalloop): Remove `evalfun' arg.
22005 Bind Qinternal_interpreter_environment.
22006 (Feval_buffer): Bind Qlexical_binding.
22007 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
22009 (syms_of_lread): Declare `lexical-binding'.
22011 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22013 * keyboard.c (eval_dyn): New fun.
22014 (menu_item_eval_property): Use it.
22016 * image.c (parse_image_spec): Use Ffunctionp.
22018 * fns.c (concat, mapcar1): Accept byte-code-functions.
22020 * eval.c (Fsetq): Handle lexical vars.
22021 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22022 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22023 (FletX, Flet): Obey lexical binding.
22024 (Fcommandp): Handle closures.
22025 (Feval): New `lexical' arg.
22026 (eval_sub): New function extracted from Feval. Use it almost
22027 everywhere where Feval was used. Look up vars in lexical env.
22029 (Ffunctionp): Move from subr.el.
22030 (Ffuncall): Handle closures.
22031 (apply_lambda): Remove `eval_flags'.
22032 (funcall_lambda): Handle closures and new byte-code-functions.
22033 (Fspecial_variable_p): New function.
22034 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22035 but without exporting it to Lisp.
22037 * doc.c (Fdocumentation, store_function_docstring):
22038 * data.c (Finteractive_form): Handle closures.
22040 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22043 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22045 (exec_byte_code): New function extracted from Fbyte_code to handle new
22046 calling convention for byte-code-functions. Add new byte-codes.
22048 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22050 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22052 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22054 * xdisp.c (redisplay_internal): Fix prototype.
22056 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22058 * xdisp.c (SCROLL_LIMIT): New macro.
22059 (try_scrolling): Use it when setting scroll_limit.
22060 Limit scrolling to 100 screen lines.
22061 (redisplay_window): Even when falling back on "recentering",
22062 position point in the window according to scroll-conservatively,
22063 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22065 (try_scrolling): When point is above the window, allow searching
22066 as far as scroll_max, or one screenful, to compute vertical
22067 distance from PT to the scroll margin position. This prevents
22068 try_scrolling from unnecessarily failing when
22069 scroll-conservatively is set to a value slightly larger than the
22070 window height. Clean up the case of PT below the margin at bottom
22071 of window: scroll_max can no longer be INT_MAX. When aggressive
22072 scrolling is in use, don't let point enter the opposite scroll
22073 margin as result of the scroll.
22074 (syms_of_xdisp) <scroll-conservatively>: Document the
22075 threshold of 100 lines for never-recentering scrolling.
22077 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22079 * dispextern.h (move_it_by_lines):
22080 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

22082 (message_log_check_duplicate): Remove parameters `prev_bol' and
22083 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22084 (redisplay_internal): Remove parameter `preserve_echo_area',
22085 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22087 * indent.c (Fvertical_motion):
22088 * window.c (window_scroll_pixel_based, Frecenter):
22089 Don't pass `need_y_p' to `move_it_by_lines'.
22091 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22093 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22094 steal a few bits to be more compact.
22095 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22096 Remove unneeded casts.
22098 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22100 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22102 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22103 binding" message (bug#7967).
22105 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22107 Fix more problems found by GCC 4.6.0's static checks.
22109 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22110 Remove unused local var.
22112 * editfns.c (Fmessage_box): Remove unused local var.
22114 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22115 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22116 Omit unused local vars.
22117 * window.c (shrink_windows): Omit unused local var.
22118 * menu.c (digest_single_submenu): Omit unused local var.
22119 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22120 Omit unused local var.
22122 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22123 Don't assume string length fits in int.
22124 (keyremap_step, read_key_sequence): Use size_t for sizes.
22125 (read_key_sequence): Don't check last_real_key_start redundantly.
22127 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22128 instead of alloca (Bug#8344).
22130 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22131 (Fbacktrace_frame): Don't assume nframes fits in int.
22133 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22135 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22138 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22140 * cm.c (calccost): Turn while-do into do-while, for clarity.
22142 * keyboard.c (syms_of_keyboard): Use the same style as later
22143 in this function when indexing through an array. This also
22144 works around GCC bug 48267.
22146 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22148 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22150 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22151 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22153 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22154 This avoids undefined behavior on integer overflow, and is a bit
22155 more convenient anyway since it is compared to a size_t variable.
22157 Variadic C functions now count arguments with size_t, not int.
22158 This avoids an unnecessary limitation on 64-bit machines, which
22159 caused (substring ...) to crash on large vectors (Bug#8344).
22160 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22161 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
22162 All variadic functions and their callers changed accordingly.

22381 * buffer.c (Fkill_all_local_variables):
22382 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22384 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22385 unconditionally since it does the check itself.
22387 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22389 Fix more problems found by GCC 4.5.2's static checks.
22391 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22392 the first time through the loop, since we know p0 < p1 then.
22393 This also avoids a gcc -Wstrict-overflow warning.
22395 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22396 leading to a memory leak, possible in functions like
22397 load_charset_map_from_file that can allocate an unbounded number
22398 of objects (Bug#8318).
22400 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22401 that could (at least in theory) be that large.
22403 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22404 This is less likely to overflow, and avoids undefined behavior if
22405 overflow does occur. All callers changed. Use strtoul to scan
22406 for the unsigned long integer.
22407 (pint2hrstr): Simplify and tune code slightly.

22423 * process.c (Fmake_network_process): Use socklen_t, not int,
22424 where POSIX says socklen_t is required in portable programs.
22425 This fixes a porting bug on hosts like 64-bit HP-UX, where
22426 socklen_t is wider than int (Bug#8277).
22427 (Fmake_network_process, server_accept_connection):
22428 (wait_reading_process_output, read_process_output):
22431 * process.c: Rename or move locals to avoid shadowing.

22441 Make tparam.h and terminfo.c consistent.
22442 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22443 Include tparam.h instead, since it declares them.
22444 * cm.h (PC): Remove extern decl; tparam.h now does this.
22445 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22446 * terminfo.c: Include tparam.h, to check interfaces.
22447 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22448 (tparam): Adjust signature to match interface in tparam.h;
22449 this removes some undefined behavior. Check that outstring and len
22450 are zero, which they always are with Emacs.
22451 * tparam.h (PC, BC, UP): New extern decls.
22453 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22454 (xftfont_open): Rename locals to avoid shadowing.

22472 (composition_update_it): Mark var as initialized.
22473 (find_automatic_composition): Mark vars as initialized,
22474 with a FIXME (Bug#8290).

22493 Fix pointer signedness.
22494 (alsa_choose_format): Remove unused local var.
22495 (wav_play): Initialize a variable to 0, to prevent undefined
22496 behavior (Bug#8278).
22498 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22500 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22502 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22503 clobbering (Bug#8298).
22504 * sysdep.c (sys_subshell): Likewise.
22505 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22507 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22508 This should get cleaned up, so that child_setup has the
22509 same signature on all platforms.
22511 * callproc.c (call_process_cleanup): Now static.
22512 (relocate_fd): Rename locals to avoid shadowing.
22514 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22516 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22517 not to be necessary, and produces flickering.
22519 2011-03-20 Glenn Morris <rgm@gnu.org>
22521 * config.in: Remove file.
22523 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

22568 Define only if needed.
22570 * unexelf.c (unexec): Name an expression,
22571 to avoid gcc -Wbad-function-cast warning.
22572 Use a different way to cause a compilation error if anyone uses
22573 n rather than nn, a way that does not involve shadowing.
22574 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22576 * deps.mk (unexalpha.o): Remove; unused.

22633 * callint.c (quotify_arg, quotify_args): Now static.
22634 (Fcall_interactively): Rename locals to avoid shadowing.

22641 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
22642 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
22643 some of which prompt warnings from gcc -Wbad-function-cast.
22644 (Fformat_time_string, Fencode_time, Finsert_char):
22645 (Ftranslate_region_internal, Fformat):

22672 (GC_STRING_CHARS): Remove; not used.
22673 (Fmemory_limit): Cast sbrk's returned value to char *.
22675 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
22676 avoids undefined behavior in theory.
22678 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
22680 Use functions, not macros, for up- and down-casing (Bug#8254).
22681 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22682 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
22683 to use the following functions instead of these macros.
22684 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22685 EMACS_INT, since callers assume the returned value fits in int.
22686 (upcase1): Likewise, for UPCASE_TABLE.
22687 (uppercasep, lowercasep, upcase): New static inline functions.
22688 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22698 (regex_compile, re_match_2_internal): Mark locals as initialized.
22699 (RETALLOC_IF): Define only if needed.
22700 (WORDCHAR_P): Likewise. This one is never needed, but is used
22701 only in a comment talking about a compiler bug, so put inside
22702 the #if 0 of that comment.
22703 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22704 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

22730 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22731 New macros, so that the caller can use some names other than
22732 gcpro1, gcpro2, etc.
22733 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22735 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22736 argument, for consistency with GCPRO2_VAR, etc: it is now the
22737 prefix of the variable, not the variable itself. All uses
22739 * dired.c (directory_files_internal, file_name_completion):
22740 Rename locals to avoid shadowing.
22742 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22743 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22744 dired.c's scmp function, had undefined behavior.
22745 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22746 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22747 * buffer.h: ... to here, because these macros use current_buffer,
22748 and the new implementation with inline functions needs to have
22749 current_buffer in scope now, rather than later when the macros
22751 (downcase, upcase1): New static inline functions.
22752 (DOWNCASE, UPCASE1): Reimplement using these functions.
22753 This avoids undefined behavior in expressions like
22754 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22755 from race conditions in accessing the global variables
22756 case_temp1 and case_temp2.
22757 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22758 * lisp.h (case_temp1, case_temp2): Remove their decls.
22759 * character.h (ASCII_CHAR_P): Move from here ...
22760 * lisp.h: ... to here, so that the inline functions mentioned
22761 above can use them.
22763 * dired.c (directory_files_internal_unwind): Now static.
22765 * fileio.c (file_name_as_directory, directory_file_name):

22768 (file_name_as_directory): Use const pointers when appropriate.
22769 (Fexpand_file_name): Likewise. In particular, newdir might
22770 point at constant storage, so make it a const pointer.
22771 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22772 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22774 (Fset_file_times, Finsert_file_contents, auto_save_error):

22779 to avoid shadowing.
22781 * marker.c (bytepos_to_charpos): Remove; unused.
22783 * lisp.h (verify_bytepos, count_markers): New decls,
22784 so that gcc does not warn that these functions aren't declared.
22786 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22787 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22788 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22789 (copy_text): Remove unused local var.

22792 (lock_file_1): Rename local to avoid shadowing.
22794 * buffer.c (fix_overlays_before): Mark locals as initialized.
22795 (fix_start_end_in_overlays): Likewise. This function should be
22796 simplified by using pointers-to-pointers, but that's a different
22798 (switch_to_buffer_1): Now static.
22799 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22800 (report_overlay_modification): Rename locals to avoid shadowing.

22805 to suppress a gcc -Wclobbered warning that does not seem to be right.
22806 (MAXPATHLEN): Define only if needed.
22808 * process.c (serial_open, serial_configure): Move decls from here ...
22809 * systty.h: ... to here, so that they can be checked.
22811 * fns.c (get_random, seed_random): Move extern decls from here ...
22812 * lisp.h: ... to here, so that they can be checked.
22814 * sysdep.c (reset_io): Now static.

22823 (describe_map_tree):
22824 Rename locals to avoid shadowing.
22826 * keyboard.c: Declare functions static if they are not used elsewhere.

22974 1152921504606846976) returns the obviously-bogus value (-948597
22975 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
22976 reports time overflow. See
