25 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
26 This bug was introduced by my 2013-02-25 change that simplified
27 data_start configuration. Without this change, on GNU/Linux
28 an Emacs configured with --enable-profiling fails immediately
29 due to a profiler signal.

31 with these flags. On platforms where special flags are needed
32 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.

109 This makes it easier to visualize quantities on a number line.
110 This patch doesn't apply to all such range checks,
111 only to the range checks affected by the 2013-03-24 change.
112 This patch reverts most of the 2013-03-24 change.

241 Use contents slot, not buffer, where appropriate.
242 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
243 to avoid deleted windows. Use contents slot instead of buffer.
244 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:
245 * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c:

585 source bytes directly.
586 (produce_chars): Call insert_from_gap with the new arg 0.
587 (encode_coding): Likewise.

621 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
622 too so that these builds can use Cygwin's file conversion
623 functions. (We've been building and linking cygw32.o all along
624 and just not using it.)
626 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
628 File synchronization fixes (Bug#13944).
629 * Makefile.in (LIB_FDATASYNC): New macro.

643 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
645 * xdisp.c (init_iterator): Simplify because both character and byte
646 positions are either specified or -1. Add eassert. Adjust comment.
647 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
648 character and byte positions can be obtained from marker.

667 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
668 Include <sys/param.h> unconditionally, as that works elsewhere and
669 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
670 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
673 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>

751 (adjust_after_insert): Call adjust_after_replace with the new arg
754 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
756 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
757 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
758 from Elisp via unread-command-events.
760 * keyboard.c (access_keymap_keyremap): Accept nil return value from
761 functions to mean "no change".
763 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
765 region-cache.c, scroll.c, search.c: Use bool for booleans.
766 * lisp.h (compile_pattern):
767 * scroll.c (do_scrolling, do_direct_scrolling):
768 * search.c (struct regexp_cache, compile_pattern_1)
769 (compile_pattern, string_match_1, search_command)
770 (trivial_regexp_p, search_buffer, Freplace_match, match_limit)
771 (search_regs_saved, Fregexp_quote):
772 Use bool for boolean.
773 * region-cache.c (region_cache_forward, region_cache_backward):
774 Fix comments to match code: these functions return int, not boolean.
776 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
778 * search.c (find_newline): Accept start and end byte positions
779 as arguments and allow -1 if not known.

785 Adjust call to find_newline.
786 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

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

818 when you need just to move to the previous buffer position.
819 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
821 2013-03-07 Eli Zaretskii <eliz@gnu.org>
823 * .gdbinit (prowlims): Display the enabled_p flag of the row.
825 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>
827 Avoid character to byte conversions in motion subroutines.
828 * indent.h (compute_motion, vmotion): Add byte position argument.

894 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
896 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
897 * sysdep.c (list_system_processes)
898 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
899 Make it a stub in this case; otherwise the build might fail,
900 and this code hasn't been tested on such hosts anyway.
901 Problem reported by Nelson H. F. Beebe in
902 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
903 and analyzed by Jérémie Courrèges-Anglas in
904 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
906 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
908 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
909 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
910 (get_visually_first_element, move_it_vertically_backward): Ajust users.
911 * bidi.c (bidi_find_paragraph_start): Likewise.
912 * indent.c (vmotion): Likewise.
914 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
916 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
917 * filelock.c: Include <c-ctype.h>.
918 (MAX_LFINFO): New top-level constant.
919 (lock_info_type): Remove members pid, boot_time. Add members at,
920 dot, colon. Change user member to be the entire buffer, not a
921 pointer. This allows us to handle the case where a foreign
922 pid or boot time exceeds the local range. All uses changed.
923 (LINKS_MIGHT_NOT_WORK): New constant.
924 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
925 (defined_WINDOWSNT): Remove.
926 (MAKE_LOCK_NAME, file_in_lock_file_name):
927 Always use .#FILE (not .#-FILE) for the file lock,
928 even if it is a regular file.
929 (rename_lock_file): New function.
930 (create_lock_file): Use it.
931 (create_lock_file, read_lock_data):
932 Prefer a symbolic link for the lock file, falling back on a
933 regular file if symlinks don't work. Do not try to create
934 symlinks on MS-Windows, due to security hassles. Stick with
935 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
936 link, rename, unlink, mkstemp) when creating locks, as a GNUish
937 host may be using a Windowsish file system, and cannot use
938 MS-Windows-only system calls. Fall back on mktemp if mkstemp
939 doesn't work. Don't fail merely because of a symlink-contents
940 length limit in the current file system; fall back on regular
941 files. Increase the symlink contents length limit to 8 KiB, this
942 should be big enough for any real use and doesn't crunch the
944 (create_lock_file, lock_file_1, read_lock_data):
945 Simplify allocation of lock file buffers now that they fit in 8 KiB.
946 (lock_file_1): Return error number, not bool. All callers changed.
947 (ELOOP): New macro, if not already defined.
948 (read_lock_data): Return size of lock file contents, not Lisp object.
949 All callers changed. Handle a race condition if some other process
950 replaces a regular-file lock with a symlink lock or vice versa,
951 while we're trying to read the lock.
952 (current_lock_owner): Parse contents more carefully, to help avoid
953 confusing a regular-file lock with some other application's use
954 of the file. Check for lock file contents being too long, or
955 not parsing correctly.
956 (current_lock_owner, lock_file):
957 Allow foreign pid and boot times that exceed the local range.
958 (current_lock_owner, lock_if_free, lock_file):
959 Simplify allocation of lock file contents.
960 * w32.c (sys_rename_replace): New function, containing most of
961 the contents of the old sys_rename.
962 (sys_rename): Use it.
963 (fchmod): New dummy function.
964 * w32.h (sys_rename_replace, fchmod): New decls.
966 2013-03-05 Eli Zaretskii <eliz@gnu.org>
968 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
969 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
970 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
971 <dmantipov@yandex.ru>.
973 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
975 * composite.c (get_composition_id, fill_gstring_header):
976 Use make_uninit_vector where appropriate.
977 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
978 * xselect.c (clean_local_selection_data): Likewise.
980 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
982 Fix misuse of ImageMagick that caused core dump (Bug#13846).
983 * image.c (imagemagick_load_image): Calculate height and width
984 after flattening the image, not before.
986 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
988 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
989 * ftfont.c (ftfont_shape_by_flt): Likewise.
990 * w32uniscribe.c (uniscribe_shape): Likewise.
992 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
994 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
995 The old approach, which fell back on DIR/.#FILE.0 through
996 DIR/.#FILE.9, had race conditions that could not be easily fixed.
997 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
998 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
999 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1000 because the locking mechanism was never reliable in that case).
1001 This patch fixes this and other bugs discovered by a code
1002 inspection that was prompted by
1003 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1004 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1005 to avoid interoperability problems between the MS-Windows and
1006 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1007 instances of Emacs now ignore each others' locks.
1008 * filelock.c (defined_WINDOWSNT): New constant.
1009 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1010 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1011 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1012 regular files on MS-Windows hosts.
1013 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1014 Use SAFE_ALLOCA to avoid problems with long file names.
1015 (MAX_LFINFO): Now a local constant, not a global macro.
1016 (IS_LOCK_FILE): Remove.
1017 (lock_file_1): Don't inspect errno if symlink call succeeds;
1018 that's not portable.
1019 (lock_file): Document that this function can return if lock
1021 (lock_file): Don't access freed storage.
1023 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
1025 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
1027 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1029 * textprop.c: Use bool for booleans.
1030 (validate_interval_range, Fadd_text_properties)
1031 (Fremove_text_properties): Prefer bool to int when either works.
1033 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1035 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1036 If the interval tree changes as a side effect of calling
1037 modify_region, re-do processing starting from the call to
1038 validate_interval_range. (Bug#13743)
1040 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1042 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1045 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1047 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1048 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1049 access to the lock file until it is written and closed.
1052 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1054 * callint.c (Qcall_interactively):
1055 * macros.c (Qexecute_kbd_macro):
1058 2013-02-26 Bastien Guerry <bzg@gnu.org>
1060 * window.c (Frecenter): Tiny docstring enhancement.
1062 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1064 Minor textprop integer cleanup.
1065 * intervals.h, textprop.c (add_text_properties_from_list):
1066 Return void, not int, since nobody uses the return value.
1067 * textprop.c (validate_plist, add_properties, remove_properties)
1068 (Fadd_text_properties):
1069 Don't assume list length fits in int.
1070 (interval_has_all_properties, interval_has_some_properties)
1071 (interval_has_some_properties_list, add_properties, remove_properties)
1072 (Fadd_text_properties, Fremove_text_properties)
1073 (Fremove_list_of_text_properties, text_property_stickiness):
1074 Use bool for booleans.
1075 (Fadd_text_properties, Fremove_text_properties):
1076 (Fremove_list_of_text_properties):
1077 Reindent do-while as per GNU style.
1079 2013-02-25 Eli Zaretskii <eliz@gnu.org>
1081 Implement CLASH_DETECTION for MS-Windows.
1083 * filelock.c [WINDOWSNT]: Include w32.h.
1084 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1085 function of that name. Up-case the macro arguments.
1086 (IS_LOCK_FILE): New macro.
1087 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1088 (create_lock_file): New function, with body extracted from
1090 [WINDOWSNT]: Implement lock files by writing a regular file with
1091 the lock information as its contents.
1092 (read_lock_data): New function, on Posix platforms just calls
1094 [WINDOWSNT]: Read the lock info from the file.
1095 (current_lock_owner): Call read_lock_data instead of calling
1096 emacs_readlinkat directly.
1097 (lock_file) [WINDOWSNT]: Run the file name through
1100 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1101 just check if the process by that PID exists.
1103 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1104 also present, as doing so will fail to error out if the file
1107 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1109 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1110 (Fremove_list_of_text_properties): Skip all of the intervals in
1111 the region between START and END that already have resp. don't
1112 have the requested properties, not just the first one.
1113 Add assertions that the loop afterwards always modifies the
1114 properties. (Bug#13743)
1116 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1118 * callint.c (Fcall_interactively): Use the right lexical environment
1119 for `interactive' specs (bug#13811).
1120 * eval.c (Feval): Accept a lexical environment.
1122 2013-02-25 Paul Eggert <eggert@cs.ucla.edu>
1124 Simplify data_start configuration (Bug#13783).
1125 This is a followon simplification to the fix for Bug#13650.
1126 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
1127 (START_FILES): Remove. All uses removed.
1128 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
1129 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
1130 (buildobj.h): Use it.
1131 ($(ALLOBJS)): Depend on globals.h.
1132 (temacs$(EXEEXT)): Use $(ALLOBJS).
1133 * autodeps.mk (ALLOBJS): Move to Makefile.in.
1134 * deps.mk (vm-limit.o):
1135 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
1136 Do not depend on mem-limits.h.
1137 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
1138 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
1139 [__GNUC__ && !ORDINARY_LINK]: Remove.

1143 (make_hdr): Use DATA_START instead of start_of_data.
1144 * vm-limit.c: Move most of mem-limits.h's contents here.
1145 (data_start): New decl. It's OK if this is approximate,
1146 so simplify-away some unnecessary exactness.
1147 (POINTER): Remove; all uses removed.
1148 (data_space_start): Now char *, to avoid casts.
1149 (exceeds_lisp_ptr): New function, replacing the old
1150 EXCEEDS_LISP_PTR macro. All uses changed.
1151 (check_memory_limits): Simplify and remove casts.
1152 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.
1153 (memory_warnings): Use data_start instead of start_of_data.
1155 2013-02-24 Andreas Schwab <schwab@linux-m68k.org>
1157 * xdisp.c (set_message): Only check for debug-on-message if STRING
1158 is a string. (Bug#13797)
1160 2013-02-24 Paul Eggert <eggert@cs.ucla.edu>
1162 Fix regression introduced by July 10 filelock.c patch.
1163 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
1164 2012-07-10 patch to this file. Reported by Eli Zaretskii in
1165 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
1166 and diagnosed by Andreas Schwab in
1167 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
1169 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
1171 Assume C89 or better.
1172 * ralloc.c (SIZE, POINTER, NIL):
1173 * vm-limit.c (POINTER):
1174 Remove, replacing all uses with C89 equivalents. These old
1175 symbols were present only for porting to pre-C89 platforms.
1177 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1179 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
1180 This avoids warning messages reported as part of Bug#13546.
1182 2013-02-21 Ken Brown <kbrown@cornell.edu>
1184 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
1186 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
1188 * sheap.c (report_sheap_usage): Prefer message1_nolog.
1190 * keyboard.c (Qcommand_execute): New var.

1195 2013-02-19 Daniel Colascione <dancol@dancol.org>
1197 * sheap.c (report_sheap_usage): Use message, not message1, so
1198 that we don't try to create a buffer while we're in the middle
1199 of dumping Emacs. Explain why.
1201 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
1203 * search.c (find_newline): Return byte position in bytepos.
1205 (find_next_newline_no_quit, find_before_next_newline):
1206 Add bytepos argument.
1207 * lisp.h (find_newline, find_next_newline_no_quit)

1213 (get_visually_first_element, move_it_vertically_backward):
1214 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
1216 2013-02-19 Eli Zaretskii <eliz@gnu.org>
1218 * w32proc.c (new_child): Avoid leaking handles if the subprocess
1219 resources were not orderly released.
1221 2013-02-17 Eli Zaretskii <eliz@gnu.org>
1223 * xdisp.c (x_draw_vertical_border): For a window that is neither
1224 the leftmost nor the rightmost, redraw both the left and the right
1225 vertical borders. (Bug#13723)

1247 * w32.c (sys_chown): Remove unused function.
1249 * w32term.c <input_signal_count>: Declare 'volatile'
1250 unconditionally. (Bug#9066)
1252 * w32.c (set_errno): Reset h_errno and don't set it to any other
1253 value. Set errno instead.
1254 (check_errno): Reset h_errno.
1255 (sys_socket, socket_to_fd, sys_bind, sys_connect)
1256 (sys_gethostname, sys_getservbyname, sys_getpeername)
1257 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
1258 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set

1266 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1268 * keyboard.c (read_char): Fix calculation of auto-save time out
1269 when auto-save-timeout is less than 4. (Bug#13720)
1271 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
1272 time. Improve diagnostics in DebPrint. (Bug#13546)

1278 make sure errno is set to an appropriate value. (Bug#13546)
1279 (socket_to_fd): Add assertion against indexing fd_info[] with a
1280 value that is out of bounds.
1281 (sys_accept): If fd is negative, do not set up the child_process
1282 structure for reading.
1284 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
1286 * composite.c (fill_gstring_header): Remove useless prototype.

1298 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1300 Fix AIX port (Bug#13650).
1301 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1302 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1303 was #undeffed earlier, so it cannot be used as a macro here.
1304 Use the constant and not the macro.
1306 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1308 * w32proc.c (new_child): If no vacant slots are found in
1309 child_procs[], make another pass looking for slots whose process
1310 has exited or died. (Bug#13546)
1312 * w32.c (sys_pipe): When failing due to file descriptors above
1313 MAXDESC, set errno to EMFILE.
1314 (_sys_read_ahead): Update cp->status when failing to read serial
1315 communications input, so that the status doesn't stay at
1316 STATUS_READ_IN_PROGRESS. (Bug#13546)
1318 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1320 * gtkutil.c (tb_size_cb): New function.
1321 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
1323 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1325 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
1328 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
1330 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1332 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
1334 * font.c (font_range): Add pos_byte argument. Adjust comment
1335 and break long line.
1336 * font.h (font_range): Adjust prototype.
1337 * composite.c (autocmp_chars): Pass byte position to font_range.
1338 Break long line. Remove useless prototype and format comment.
1340 2013-02-13 Glenn Morris <rgm@gnu.org>
1342 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1344 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1346 Improve AIX port some more (Bug#13650).
1347 With this, it should be as good as it was in 23.3, though it's
1348 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1349 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1350 * unexaix.c (start_of_text): Remove.
1351 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1352 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1353 (orig_load_scnptr, orig_data_scnptr):
1354 Now off_t, not long, since they are file offsets.
1355 (make_hdr): Use _data, not start_of_data ().
1356 This is the key part of the fix.
1357 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1358 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1360 * pre-crt0.c (data_start): Initialize to 1.
1361 This ports to compilers that optimize the external declaration
1362 'int x = 0;' as if it were 'int x;' to shrink the executable.
1364 Improve AIX port (Bug#13650).
1365 This doesn't fix the bug, but it makes progress: Emacs builds now.
1366 * unexaix.c: Include inttypes.h, stdarg.h.
1367 (report_error, report_error_1): Mark as _Noreturn.
1368 (report_error): Don't report the wrong errno.
1369 (report_error_1): Now varargs. All callers changed.
1370 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1371 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1372 (write_ptr): Use %p to print address rather than %lx and a cast
1373 to unsigned long. Grow buffer a bit, to be safer.
1375 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1377 * bidi.c (bidi_resolve_neutral): After finding the next
1378 non-neutral character, accept NEUTRAL_ON type as well, because
1379 directional control characters, such as LRE and RLE, have their
1380 type converted to that by bidi_resolve_weak. This avoids aborts
1381 when LRE/RLE follows a run of neutrals.
1382 (bidi_move_to_visually_next): Assert that return value of
1383 bidi_peek_at_next_level is non-negative. Negative values will
1386 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1388 Minor getenv-related fixes.
1389 * callproc.c (Fcall_process_region) [!DOS_NT]:
1390 Avoid unnecessary duplicate call to getenv.
1391 * callproc.c (init_callproc):
1392 * dispnew.c (init_display):
1393 * sysdep.c (sys_subshell):
1394 Omit unnecessary cast of getenv or egetenv.
1396 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1398 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1399 Update dependencies.

1403 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1405 (display_line): Set w->region_showing to the value of
1406 it->region_beg_charpos, not to -1. This fixes redisplay
1407 optimization when cursor is moved up after M->. (Bug#13623)
1409 (try_scrolling): Scroll text up more if point is too close to ZV
1410 and inside the scroll margin. This makes sure point is moved
1411 outside the scroll margin in these cases.
1413 * window.h (struct window): region_showing can no longer be
1416 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>

1421 * search.c (find_newline, scan_newline):
1422 * xdisp.c (pos_visible_p, display_count_lines):
1423 Use memchr and memrchr rather than scanning byte-by-byte.
1424 * search.c (find_newline): Rename from scan_buffer.
1425 Omit first arg TARGET, as it's always '\n'. All callers changed.
1427 Clean up read_key_sequence a tiny bit more.

1429 (read_key_sequence): Remove unused locals.
1431 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>

1438 (active_maps): New function.
1439 (test_undefined): Also return true for nil bindings.
1440 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1441 a single (composed) keymap. Remember `first_event' to choose the right
1442 set of active keymaps. Recompute the set of keymaps after receiving
1443 the first event. Remove GOBBLE_FIRST_EVENT.
1444 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1445 * keyboard.h (read_char): Update declaration.
1446 * lread.c (read_filtered_event): Adjust call to read_char.

1452 in the window. (Bug#13675)
1454 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1456 * marker.c (set_marker_internal): If desired position is passed
1457 as a marker, avoid call to buf_charpos_to_bytepos.
1458 * window.c (Fset_window_point): Omit redundant type checking.
1459 (Fset_window_start): Likewise. Format comment.
1460 (window_scroll_pixel_based): Use set_marker_restricted_both
1461 with character and byte positions obtained from an iterator.
1462 (Fset_window_configuration): Use set_marker_restricted_both.
1463 * xdisp.c (message_dolog): Likewise.
1465 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1467 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1468 When text lines are longer than window's screen lines, don't move back
1469 too far. This speeds up some redisplay operations. (Bug#13675)
1471 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1473 * syntax.c (scan_sexps_forward): Fix byte position calculation

1485 (sxhash_float): Return EMACS_UINT, for consistency with the other
1487 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1488 non-static inline function and therefore can't use static vars.
1489 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1490 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1491 with the other hash functions.
1493 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1495 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1496 XXXXXX part of the temporary file pattern is not downcased even
1497 when w32-downcase-file-names is non-nil. (Bug#13661)
1499 * xdisp.c (decode_mode_spec): Remove handling of %t.
1501 * msdos.c (careadlinkatcwd): Remove.
1503 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1505 * lread.c (skip_dyn_bytes): New function (bug#12598).
1506 (read1): Use it. Use getc instead of READCHAR to read bytes.

1541 argument is known to be a vector.
1542 * fns.c (Flocale_info): Likewise for ASET.
1543 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1544 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1546 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1548 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1551 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
1552 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
1553 updateCollectionBehaviour.
1555 * nsterm.m (NEW_STYLE_FS): Remove.
1556 (ns_last_use_native_fullscreen): New variable.
1557 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
1558 (x_set_window_size): Do not take title bar and tool bar into account
1559 if isFullscreen returns YES.
1560 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1561 (check_native_fs): New function.
1562 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.

1565 and tool bar if isFullscreen returns NO.
1566 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
1567 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
1568 with HAVE_NATIVE_FS.

1578 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1579 (syms_of_nsterm): Add ns-use-native-fullscreen.
1581 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1583 * fileio.c (Qchoose_write_coding_system): Now static.
1585 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1587 * xdisp.c (window_buffer_changed): region_showing can be negative,
1588 which still means region is being displayed.
1589 (redisplay_internal): Resurrect code that forced redisplay of the
1590 whole window when showing region and the mark has changed.
1591 Record the new mark position to allow redisplay optimizations.
1592 (display_line): If it->region_beg_charpos is non-zero, set the
1593 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1595 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1596 not bitfield of 1 bit.
1598 2013-02-03 Daniel Colascione <dancol@dancol.org>
1600 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1601 daemon mode works on cygw32 when Emacs is installed and not just
1604 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1606 Avoid file time stamp bug on MS-Windows (Bug#13149).
1607 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1608 as FAT32 doesn't update time stamps when truncating them.
1609 Also, check that a file time stamp is not a multiple of 100 ns;
1610 this should catch all instances of the problem on MS-Windows,
1611 as its native file system resolution is 100 ns or worse, and
1612 checking for a non-multiple of 100 ns should impose only a small
1613 overhead on systems with ns resolution.
1615 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1617 Avoid encoding file names on MS-Windows when they need to be run
1618 through dostounix_filename.
1619 * w32.c (normalize_filename): Accept an additional argument
1620 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1621 downcase it even if w32-downcase-file-names is non-nil.
1622 (dostounix_filename): Accept an additional argument MULTIBYTE and
1623 pass it to normalize_filename.
1624 (emacs_root_dir): Adjust.
1626 * msdos.h (dostounix_filename): Adjust prototype.
1628 * w32.h (dostounix_filename): Adjust prototype.
1630 * msdos.c (dostounix_filename): Accept an additional argument and
1632 (init_environment): Adjust callers of dostounix_filename.
1634 * fileio.c (Ffile_name_directory, file_name_as_directory)
1635 (directory_file_name, Fexpand_file_name)
1636 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1638 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1640 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1641 variables, as egetenv is case-insensitive for DOS_NT.
1643 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1644 with an encoded file name.
1646 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1647 Adjust calls to dostounix_filename.
1649 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1651 * unexw32.c (unexec): Adjust call to dostounix_filename.
1653 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1655 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1658 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1661 * callproc.c (Fcall_process): Make sure program name in PATH and
1662 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1663 is passed to exec/spawnve, which fails unless the file-name
1666 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1667 even if w32-quote-process-args is nil.
1669 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1671 Fix timestamp bug when write-region appends nothing (Bug#13149).
1672 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1673 the file's time stamp doesn't change if Emacs happens to write nothing
1674 to the file, and on a buggy file system this could cause Emacs to
1675 incorrectly infer that the file system doesn't have the bug.
1676 Avoid this problem by inhibiting the inference in this case.
1678 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1680 * window.h (struct window): Convert base_line_number, base_line_pos
1681 and column_number_displayed members from Lisp_Object to ptrdiff_t.

1685 (make_window): Initialize column_number_displayed.
1686 * print.c (print_object): Follow the printed representation of
1687 frames and print window pointer to distinguish between windows.

1691 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1692 (try_scrolling, try_cursor_movement, redisplay_window)
1693 (try_window_reusing_current_matrix, try_window_id, display_line)
1694 (display_mode_lines, decode_mode_spec): Adjust users.
1695 * .gdbinit (pwinx): Do not print sequence_number.
1697 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1699 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1700 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1701 * dired.c: Include <fcntl.h>.
1702 (open_directory): New function, which uses open and fdopendir
1703 rather than opendir. DOS_NT platforms still use opendir, though.

1705 (file_attributes): New function, with most of the old Ffile_attributes.
1706 (directory_files_internal, Ffile_attributes): Use it.
1707 (file_attributes, file_name_completion_stat): First arg is now fd,
1708 not dir name. All uses changed. Use fstatat rather than lstat +
1710 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1711 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1712 (emacs_readlinkat): New function, with much of the old
1713 Ffile_symlink_p, but with an fd argument for speed.
1714 It uses readlinkat rather than careadlinkatcwd, so that it
1715 need not assume the working directory.
1716 (Ffile_symlink_p): Use it.
1717 * filelock.c (current_lock_owner): Use emacs_readlinkat
1718 rather than emacs_readlink.
1719 * lisp.h (emacs_readlinkat): New decl.
1720 (READLINK_BUFSIZE, emacs_readlink): Remove.
1721 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1722 (emacs_norealloc_allocator, emacs_readlink): Remove.
1723 This stuff is moved to fileio.c.
1724 * w32.c (fstatat, readlinkat): New functions.
1725 (careadlinkat): Don't check that fd == AT_FDCWD.
1726 (careadlinkatcwd): Remove; no longer needed.

1738 (sys_close): Zero out the flags for the file descriptor before
1739 closing it. (Bug#13546)
1741 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1742 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1743 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1746 * w32.c (w32_get_long_filename, init_environment, readlink):
1747 Support file names encoded in DBCS codepages.
1748 (readlink): Use the current file-name-coding-system, not the ANSI
1749 codepage, to decode and handle targets of symlinks.
1751 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1753 * w32.c (opendir): Now accepts a 'const char *'.
1755 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>

1760 (Vredisplay_preemption_period): Likewise.
1761 (update_frame, update_single_window, update_window, update_frame_1):
1762 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1763 used, following the 2012-06-22 change.
1765 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1767 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1769 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1771 * font.c (num_fonts): Remove the leftover from old
1772 debugging code. Adjust comment style here and there.
1773 * insdel.c (insert_1): Remove.
1774 * lisp.h (insert_1): Remove prototype.
1775 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1777 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1779 * w32.c (max_filename_mbslen): New function.
1780 (normalize_filename, readdir): Use it to detect locales where ANSI
1781 encoding of file names uses a double-byte character set (DBCS).
1782 If a DBCS encoding is used, advance by characters using
1783 CharNextExA, instead of incrementing a 'char *' pointer.
1784 Use _mbslwr instead of _strlwr. (Bug#13515)
1786 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1787 request of memory reservation to 1.7GB. (Bug#13065)

1797 Avoid redundant calls to strlen.
1799 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1801 Drop async_visible and async_iconified fields of struct frame.
1802 This is possible because async input is gone; for details, see
1803 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1804 * frame.h (struct frame): Remove async_visible and async_iconified
1805 members, convert garbaged to unsigned bitfield. Adjust comments.

1807 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1808 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:

1810 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1812 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1813 properly. Likewise for obscured.

1823 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1825 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1827 * xdisp.c (message2, message2_nolog): Remove functions.
1828 (message3, message3_nolog): Extract nbytes and multibyteness directly
1829 from the string. Change all callers.
1830 (message3_nolog): Don't set message_enable_multibyte since set_message
1831 will reset it anyway.
1832 (message1, message1_nolog): Use message3.
1833 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1834 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1835 (set_message): Drop all but the second arg, which has to be a string.
1836 (set_message_1): Simplify now that we know that a1 is NULL and the
1837 second arg is a string.
1838 * frame.h (struct frame): Remove `message_buf' field.
1839 Use glyphs_initialized_p instead.
1840 (FRAME_MESSAGE_BUF): Remove macro.

1846 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1847 to correctly handle multibyte strings.
1848 * frame.c (delete_frame): Don't free message_buf any more.
1849 * editfns.c (message_text, message_length): Remove vars.
1850 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1851 * fileio.c (auto_save_error): Use message3 instead of message2.
1852 * dispnew.c (adjust_frame_message_buffer): Remove function.
1854 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1856 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1857 real estate used for the tool bar and the menu bar.
1859 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1861 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1862 hidden buffer is prepared to modification (Bug#13164).
1864 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1866 * window.h (struct window): Change window_end_valid member from
1867 Lisp_Object to a bitfield. Adjust comments.
1868 (wset_window_end_valid): Remove.
1869 * window.c (adjust_window_count): Clear window_end_valid.
1870 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1871 (Fwindow_line_height, set_window_buffer, Frecenter)
1872 (Fsplit_window_internal, Fdelete_other_windows_internal)
1873 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1874 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1875 * xdisp.c (check_window_end, reconsider_clip_changes)
1876 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1877 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1878 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1880 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1882 * xdisp.c (mark_window_display_accurate): Simplify the loop
1883 assuming that the only one of vchild, hchild or buffer window
1884 slots is non-nil. Call mark_window_display_accurate_1 for
1885 the leaf windows only.
1886 (mark_window_display_accurate_1): Always assume leaf window.
1889 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1891 * emacs.c (Qkill_emacs_hook): Now static.
1893 * fileio.c (Finsert_file_contents): Simplify.
1894 Remove unnecessary assignments and tests.
1896 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1898 * w32.c (acl_set_file): Don't test for errors unless
1899 set_file_security returns FALSE. Avoids spurious errors when
1902 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1904 * fileio.c (Finsert_file_contents): Revert code introduced at
1905 2013-01-18 in favor of the simpler and generally better fix.
1906 Save stack space by removing 'buffer' and reusing 'read_buf'
1909 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1911 * lisp.h (eabs): Define unconditionally (Bug#13419).
1912 The old "#if !defined (eabs)" was an unnecessary revenant of back
1913 when this macro was called "abs". Document 'eabs' better.
1915 2013-01-19 Glenn Morris <rgm@gnu.org>
1917 * fns.c (Frandom): Doc fix.
1919 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1921 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1922 segfault when there are lots of overlays.
1924 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1925 when there are lots of overlays.
1926 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1927 for the details and a way to reproduce.
1929 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1931 * fileio.c: Use O_APPEND to append.
1932 This corresponds better to the natural interpretation of "append",
1933 and avoids the need to open the output file twice, or to invoke
1934 lseek when APPEND is neither nil nor a number.
1935 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1936 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1937 file possibly twice, and lseeking to its end; this avoids the
1938 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1939 at the same time: the combination is never needed and apparently
1940 it doesn't work with DOS_NT.
1942 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1943 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1945 Allow floating-point file offsets.
1946 Problem reported by Vitalie Spinu in
1947 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1948 * fileio.c (emacs_lseek): Remove.
1949 (file_offset): New function.
1950 (Finsert_file_contents, Fwrite_region): Use it.
1952 2013-01-19 Chong Yidong <cyd@gnu.org>
1954 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1955 aborting on Fsignal (Bug#13289).
1957 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1959 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1960 set_file_security as failure due to insufficient privileges.
1961 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1962 (fstat): Return owner and group like 'stat' and 'lstat' do.
1964 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1966 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1967 The bug was observed on Ubuntu operating inside a virtual machine,
1968 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1969 The workaround introduces a race condition on non-buggy hosts,
1970 but it's an unlikely race and anyway there's a nearly identical
1971 nearby race that can't be fixed.
1972 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1974 (Fwrite_region): Test for file system time stamp bug.
1975 (init_fileio): New function.
1976 * lisp.h (init_fileio): Declare it.
1977 * emacs.c (main): Call it.
1979 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1980 and make it more consistent with other stat-failure diagnostics.
1982 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1984 Fix crash when inserting data from non-regular files.
1985 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1986 for the error description produced by valgrind.
1987 * fileio.c (read_non_regular): Rename to read_contents.
1988 Free Lisp_Save_Value object used to pass parameters.
1989 (read_non_regular_quit): Rename to read_contents_quit.
1990 (Finsert_file_contents): Redesign internal file reading loop to adjust
1991 gap and end positions after each read and so help make_gap to work
1992 properly. Do not signal an I/O error too early and so do not leave
1993 not yet decoded characters in a buffer, which was the reason of
1994 redisplay crash. Use list2 to build return value. Adjust comments.
1996 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1998 Close a race when statting and reading files (Bug#13149).
1999 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2000 This avoids a race if the file is renamed between stat and open.
2001 This race is not the problem originally noted in Bug#13149;
2002 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2004 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

2011 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2012 * alloc.c (format_save_value): Rename to make_save_value.
2013 (make_save_pointer): New function.
2014 (record_xmalloc): Use make_save_pointer.
2015 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2016 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2017 Change users of make_save_value to make_save_pointer.
2018 Likewise for format_save_value and make_save_value.

2031 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2033 * keymap.c (map_keymap_internal): Use format_save_value.
2034 (map_keymap_char_table_item): Adjust accordingly.
2035 * fileio.c (non_regular_fd, non_regular_inserted)
2036 (non_regular_nbytes): Remove.
2037 (Finsert_file_contents): Convert trytry to ptrdiff_t.
2038 Use format_save_value to pass parameters to read_non_regular.
2039 (read_non_regular): Use XSAVE_ macros to extract parameters.
2041 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
2043 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
2045 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2047 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2048 extraction from any Lisp_Save_Value slot. Add type checking.
2049 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
2050 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
2051 * xselect.c: All users changed.
2053 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

2061 object with the specified internal structure.
2062 (make_save_value): Reimplement using format_save_value.
2063 * editfns.c (save_excursion_save): Use format_save_value.
2064 (save_excursion_restore): Use XSAVE_OBJECT.
2066 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
2068 Avoid needless casts with XSAVE_POINTER.
2069 * alloc.c (mark_object) [GC_MARK_STACK]:
2070 * dired.c (directory_files_internal_unwind):
2071 * fileio.c (do_auto_save_unwind):
2072 * gtkutil.c (pop_down_dialog):
2073 * keymap.c (map_keymap_char_table_item):
2074 * lread.c (load_unwind):
2075 * nsmenu.m (pop_down_menu):
2076 * print.c (print_object) [GC_MARK_STACK]:
2077 * xfns.c (clean_up_file_dialog):
2078 * xmenu.c (cleanup_widget_value_tree):
2079 Omit casts between XSAVE_POINTER and a pointer type.
2081 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2083 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
2084 * eval.c (eval_sub): Protect `form' from being GCed before its
2085 car and cdr becomes protected with the backtrace entry.
2087 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2089 Make Lisp_Save_Value more versatile storage for up to four objects.

2099 (free_save_value): Likewise.
2100 (mark_object): Likewise.
2101 * editfns.c (save_excursion_save): Pack everything within
2102 Lisp_Save_Value and so avoid xmalloc.
2103 (save_excursion_restore): Adjust to match new layout. Use free_misc
2104 because we do not allocate extra memory any more. Add eassert.
2105 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2106 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

2116 Bug#11484 with LCD smoothing on.
2118 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
2120 Fix SIGDANGER handlers, for AIX (Bug#13408).
2121 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
2122 Move handlers here from emacs.c; they were out of place.
2124 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
2126 * xterm.c (syms_of_xterm): Adjust documentation for
2127 scroll-bar-adjust-thumb-portion.

2132 determine whether scroll bar thumb size should be adjusted or
2133 not. Use variable for MOTIF.
2135 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for

2147 (nsfont_open): Move block_input earlier. Add unblock_input before early
2149 (nsfont_draw): Add block/unblock_input calls.
2151 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
2153 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
2154 for old_charpos and old_bytepos.

2158 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
2159 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
2160 Clear tzvalbuf_in_environ if this workaround is in effect.
2161 Problem and fix reported by Kazuhiro Ito.
2163 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>

2172 string cross-reference(s).
2174 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
2176 Avoid unnecessary byte position calculation for the gap movement.
2177 Since all users of move_gap do CHAR_TO_BYTE for other purposes
2178 anyway, all of them should use move_gap_both instead.
2179 * lisp.h (move_gap): Remove prototype.
2180 * insdel.c (move_gap): Remove.
2181 (move_gap_both): Add eassert.

2188 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
2190 * term.c (init_tty): Use them instead of rolling our own code.
2191 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
2192 switches from 'signal' to 'pthread_sigmask', which is safer in
2193 multithreaded applications.
2194 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
2195 which has already arranged for that.
2196 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
2197 This is the main part of the bug fix.

2206 Omit buffer_slot_type_mismatch and use generic predicates to enforce
2207 the type of per-buffer values where appropriate.
2208 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
2209 predicate, which is how it's really used now. Adjust comment.
2210 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
2211 * buffer.c (buffer_slot_type_mismatch): Remove.
2212 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

2217 right-fringe-width, scroll-bar-width and buffer-display-count.
2218 Use Qstringp for default-directory, buffer-file-name,
2219 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
2220 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
2222 * data.c (store_symval_forwarding): Adjust to call the predicate.
2224 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
2226 * w32.c (get_name_and_id, acl_set_file):
2227 * w32term.c (w32fullscreen_hook): Remove unused local variables.

2237 * insdel.c (make_gap_larger): Use GAP_BYTES_DFL. Adjust comment.
2238 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
2239 (make_gap_1): New function to adjust the gap of any buffer.
2240 * coding.c (coding_alloc_by_making_gap): Use it.
2241 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
2242 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
2244 2013-01-08 Juri Linkov <juri@jurta.org>
2246 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
2247 of (supports :underline (:style wave)). (Bug#13000)

2263 (echo_char): Use it.
2264 (read_key_sequence): When echoing mock input, ensure that the
2265 trailing dash is properly added.
2267 2013-01-05 Eli Zaretskii <eliz@gnu.org>
2269 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
2270 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
2271 digits for buffer positions, before misalignment starts.
2272 Display "0" for integer "object" field.
2273 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2274 Display the newline glyph more unambiguously.
2276 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2278 * nsterm.m (ns_draw_underwave):
2279 * w32term.c (w32_draw_underwave):
2280 * xterm.c (x_draw_underwave): Make underwave look more triangular

2284 * w32term.c (x_draw_glyph_string):
2285 * xterm.c (x_draw_glyph_string): Don't use previous underline
2286 thickness and position if previous underline type is underwave.

2306 * term.c (tty_ins_del_lines):
2307 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2308 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2310 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2312 * w32.c (unsetenv): Set up the string passed to _putenv
2314 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
2315 for the bug this caused.
2317 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
2319 * coding.c (Qmac): Now static.
2321 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2323 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
2324 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
2325 handlebox_widget. Set toolbar_in_hbox to false/true, set
2326 toolbar_is_packed to true.
2327 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
2328 (update_frame_tool_bar): Check toolbar_is_packed for packing.
2329 Show all on TOOLBAR_TOP_WIDGET.
2330 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
2331 by TOOLBAR_TOP_WIDGET.
2332 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
2333 Check toolbar_is_packed.
2334 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
2335 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2336 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
2338 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2339 (xg_update_menubar): Update title only if
2340 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2341 (xg_update_submenu): Skip tearoff only if
2342 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2343 (xg_initialize): Initialize xg_detached_menus only if
2344 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2346 * xterm.h (struct x_output): Surround handlebox_widget with
2347 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2348 toolbar_in_hbox is bool.
2350 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2352 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2353 (LIBS_GNUSTEP): Define.
2354 (LIBES): Add $(LIBS_GNUSTEP).
2355 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
2357 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2359 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2360 continuation glyph on a TTY with an indication of an empty line.
2363 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2365 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2366 file's SELinux context or ACLs successfully set, nil otherwise.
2368 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
2370 * w32proc.c (reader_thread): Avoid passing NULL handles to
2371 SetEvent and WaitForSingleObject.
2373 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2375 Port EXTERNALLY_VISIBLE to Clang 3.2.
2376 * conf_post.h (__has_attribute): New macro.
2377 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2379 2012-12-27 Glenn Morris <rgm@gnu.org>
2381 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2382 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2384 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2386 * fileio.c (file_name_as_directory, directory_file_name):
2387 Accept an additional argument MULTIBYTE to indicate whether the input C
2388 came from a multibyte or a unibyte Lisp string; all callers
2389 adjusted. Don't assume the input string is always multibyte.
2391 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2392 don't ENCODE_FILE them, and return a unibyte string if the input
2394 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2395 don't assume the input strings will always be multibyte. If the
2396 input strings are multibyte, decode strings obtained from C
2399 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2401 * lisp.h (toplevel): Add two notices to the comment about
2402 defining a new Lisp data type.
2403 * print.c (print_object): If Lisp_Save_Value object's pointer
2404 is the address of a memory area containing Lisp_Objects, try
2406 * alloc.c (valid_lisp_object_p): Adjust comment.
2408 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2410 * keyboard.c (record_asynch_buffer_change): Initialize an event
2411 only if it's really needed.
2412 * frame.h (enum output_method): Remove output_mac member since
2413 it's a leftover from the deleted code.
2414 * frame.c (Fframep): Adjust user here ...
2415 * terminal.c (Fterminal_live_p): ... and here.
2416 * coding.c (Qmac): Now here because it's only used to denote
2417 end-of-line encoding type.
2418 (syms_of_coding): DEFSYM it.
2419 * frame.h (Qmac): Remove duplicated declaration.
2421 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2423 * window.c (select_window_1): Now static, since it's used only here.
2425 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2427 * window.c (window_body_cols): Subtract display margins from the
2428 window body width on TTYs as well. See
2429 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2430 for the original report.
2432 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2434 * xdisp.c (redisplay_window): Remove inner local variable
2435 because the outer shadowed one has the same meaning.
2436 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2438 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2439 (xg_create_tool_bar): Adjust users.
2441 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2443 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2444 * buffer.c (Fget_buffer_create): Use it to set compact field of
2445 struct buffer_text to avoid accessing an uninitialized value
2446 when compact_buffer is called for the first time.
2447 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2448 (Fset_buffer_modified_p): Use buffer_window_count to check
2449 whether the buffer is displayed in some window.
2450 * xdisp.c (message_dolog): Likewise.
2452 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2454 * w32.c (acl_set_file): If setting the file security descriptor
2455 fails, and the new DACL is identical to the existing one, silently
2456 return success. This fixes problems for users backing up their
2457 own files without having the necessary privileges for setting
2458 security descriptors.
2460 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2462 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2463 after WaitForSingleObject returns normally. This expedites reader
2464 thread shutdown when delete_child triggers it.
2465 (reap_subprocess): More accurate commentary for why we call
2466 delete_child only when cp->fd is negative.
2468 * w32.c (sys_close): Do not call delete_child on a subprocess
2469 whose handle is not yet closed. Instead, set its file descriptor
2470 to a negative value, so that reap_subprocess will call
2471 delete_child on that subprocess when its SIGCHLD arrives.
2472 This avoids closing handles used for communications between sys_select
2473 and reader_thread, which doesn't give sys_select a chance to
2474 notice that the process exited and invoke the SIGCHLD handler for
2477 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2479 * nsfns.m (Fns_do_applescript): Run event loop until script has
2480 been executed (Bug#12969).
2481 (ns_run_ascript): Chech as_script for nil, set to nil after
2484 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2486 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2488 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2490 * w32term.c (w32fullscreen_hook): New function.
2491 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2493 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2495 * fileio.c (Finsert_file_contents): Doc fix.
2497 * w32proc.c (new_child, delete_child, find_child_pid): For a
2498 subprocess, consider its slot being in use as long as its process
2499 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2500 slot when a new process is started immediately after killing
2501 another one, without waiting enough time for the first process to
2502 be reaped and resources allocated for it be orderly freed.
2504 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2506 2012-12-21 Chong Yidong <cyd@gnu.org>
2508 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2510 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2512 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2514 * w32.c (get_name_and_id): Always pass NULL as the first argument
2515 of lookup_account_sid. Avoids crashes with UNC file names that
2516 refer to DFS domains, not to specific machine names. (Bug#12621)
2517 Remove now unused argument FNAME; all callers changed.
2518 (get_file_owner_and_group): Remove now unused argument FNAME; all
2521 2012-12-21 Chong Yidong <cyd@gnu.org>
2523 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2524 error for invalid chars, don't check for a nil return value.
2526 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2528 Avoid calls to CHAR_TO_BYTE if byte position is known.
2529 * editfns.c (make_buffer_string_both): Use move_gap_both.
2530 (Fbuffer_string): Use make_buffer_string_both.
2531 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2533 (buf_bytepos_to_charpos): Likewise.
2534 (charpos_to_bytepos): Remove.
2535 * fileio.c (Finsert_file_contents): Use move_gap_both.
2536 * search.c (Freplace_match): Likewise.
2537 * process.c (process_send_region): Likewise. Use convenient
2538 names for byte positions.
2539 * lisp.h (charpos_to_bytepos): Remove prototype.
2540 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2541 * insdel.c (move_gap): Likewise.
2543 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2545 * xdisp.c (redisplay_internal): Remove now-unused local.
2547 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2549 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2550 (redisplay_internal): Don't bother selecting the frame to get the
2551 proper value of frame-local variables (bug#13225).
2553 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2555 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2556 Rename 4th argument since it may be buffer or string. Adjust comment.
2557 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2559 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2561 * coding.c (Fdetect_coding_region): Do not check start and end with
2562 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2563 (code_convert_region): Likewise.
2565 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2567 * w32.c (acl_get_file, acl_set_file): Run the file name through
2568 map_w32_filename, and resolve any symlinks in the file name, like
2570 (acl_set_file): Call revert_to_self, if any privileges were
2573 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2575 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2576 ($(BLD)/w32.$(O)): Update dependencies.
2578 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2580 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2581 propagate redisplay's scrolling (if any) to the right window.
2582 (redisplay_internal): Use ensure_selected_frame.
2583 (display_mode_lines): Complete last fix.
2584 * window.c (select_window_1): New func, extracted from select_window.
2585 (select_window): Use it.
2586 * window.h (select_window_1): Declare.
2588 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2590 Emulate Posix ACL APIs on MS-Windows.
2591 * w32.c: Include sddl.h and sys/acl.h.
2592 (SDDL_REVISION_1): Define if not already defined.
2593 (g_b_init_get_security_descriptor_dacl)
2594 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
2595 (g_b_init_is_valid_security_descriptor)
2596 (g_b_init_set_file_security): New static flags.

2607 (convert_sddl_to_sd, acl_valid, acl_to_text, acl_from_text)
2608 (acl_free, acl_get_file, acl_set_file): New functions.
2610 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
2612 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2614 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2615 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2616 for some of that bug's symptoms can now cause Emacs to abort.
2617 Remove the workaround.
2618 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2619 The bug that caused SIGCHLD to get lost has been fixed, and the
2620 workaround for it can now cause Emacs to abort.
2622 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2624 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2625 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2626 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
2628 2012-12-16 Romain Francoise <romain@orebokech.com>
2630 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2631 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2632 and copy ACL entries of file in addition to SELinux context if set.
2633 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2635 * Makefile.in (LIBACL_LIBS): New macro.
2638 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
2640 * fileio.c (internal_delete_file): Use bool for boolean.
2642 2012-12-15 Eli Zaretskii <eliz@gnu.org>
2644 Fix bug #13079 on MS-Windows with temp files not being deleted.

2647 (register_child): First argument is now pid_t.
2648 (record_infile, record_pending_deletion): New prototypes.
2650 * w32proc.c (new_child): Initialize input_file and
2651 pending_deletion members of the child.
2652 (delete_child): Delete the child's temporary input file, if any,
2653 that is pending deletion.
2654 (register_child): First argument is now pid_t.
2655 (record_infile, record_pending_deletion): New functions.
2656 (reap_subprocess): Fix a typo in DebPrint string.
2657 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2659 * fileio.c (internal_delete_file): Return an int again: non-zero
2660 if delete-file succeeds, zero otherwise.
2662 * lisp.h (internal_delete_file): Adjust prototype.
2664 * callproc.c (Fcall_process): Don't overwrite infile with result
2666 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2667 asynchronous subprocess, record the name of the input file name,
2669 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2670 delete the file, record it as pending deletion when the subprocess
2673 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2675 * editfns.c [HAVE_PWD_H]: Include grp.h.
2677 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
2679 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
2681 Fix permissions bugs with setgid directories etc. (Bug#13125)
2682 * dired.c (Ffile_attributes): Return t as the 9th attribute,
2683 to mark it as a placeholder. The old value was often wrong.
2684 The only user of this attribute has been changed to use
2685 file-ownership-preserved-p instead, with its new group arg.
2686 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
2688 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
2690 * xdisp.c (select_frame_for_redisplay, display_mode_lines):
2691 Keep selected_window and selected_frame in sync.
2693 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2695 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2696 try to get accurate owner and group information from NT file
2697 security APIs. This is to make most callers of 'stat' and
2698 'lstat', which don't need that information, much faster.
2700 * dired.c (Ffile_attributes) [WINDOWSNT]:
2701 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2702 owner and group information from 'lstat'.
2704 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2706 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2707 as that confuses set-auto-coding, so insist on the head-read
2708 returning the full 1024 bytes. Let lseek compute the tail offset;
2709 less work for us. Do not ignore I/O errors when reading the tail.
2711 * xdisp.c: Minor style fixes.
2712 (init_iterator): Hoist assignment out of if-expression.
2713 (markpos_of_region): Callers now test for sign, not for -1.
2715 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
2717 Minor redisplay optimization when the region length is zero.
2718 * xdisp.c (markpos_of_region): New function.
2719 (init_iterator): Do not highlight the region of zero length.
2720 (redisplay_window): Check whether the region is of non-zero length.
2721 (try_cursor_movement): Allow if the region length is zero.
2722 (try_window_reusing_current_matrix, try_window_id): Likewise.
2724 2012-12-13 Eli Zaretskii <eliz@gnu.org>
2726 * search.c (search_buffer): Check the inverse translations of each
2727 character in pattern when the buffer being searched is unibyte.
2730 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2732 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2733 files, fixing a regression from 24.2.
2734 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2736 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2738 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2739 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2740 Remove unnecessary S_ISLNK test, as (contra the comments) this
2741 function can't copy symlinks. Improve quality of error message
2742 when attempting to copy files that are neither regular files nor
2745 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
2747 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.
2748 * gtkutil.c (xg_set_toolkit_scroll_bar_thumb):
2749 * window.c (Frecenter):
2750 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
2751 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
2753 2012-12-12 Daniel Colascione <dancol@dancol.org>
2755 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2756 the dumped Emacs is not a sparse file, greatly improving Cygwin
2757 "make bootstrap" performance.
2759 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
2761 * inotify.c (inotify_callback): Generate an Emacs event for every
2762 incoming inotify event.
2764 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2766 * xdisp.c (handle_face_prop): Fix logic of computing
2767 it->start_of_box_run_p.
2768 (append_space_for_newline): If the glyph row is R2L, reset the
2769 iterator's end_of_box_run_p flag before prepending the space glyph.
2770 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2771 iterator's start_of_box_run_p flag before prepending the stretch.
2772 (append_glyph, produce_image_glyph, append_composite_glyph)
2773 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2774 left_box_line_p and right_box_line_p flags of the glyph for R2L
2775 glyph rows. (Bug#13011)

2971 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2973 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).

2975 * dbusbind.c (Fdbus_init_bus):
2977 * xterm.c (x_term_init):

2988 no longer needed here.
2989 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
2990 Move to inside set_time_zone_rule; they don't need file scope any more.
2991 (set_time_zone_rule): Maintain the TZ=value string separately.
2992 (syms_of_editfns): Don't initialize initial_tz;
2993 init_editfns now does it.
2994 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
2995 * lisp.h (xputenv): New decl.
2997 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

3008 informative (Bug#12992).
3010 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3012 Simplify get_lim_data.
3013 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3014 Remove USG and vlimit methods; no longer used these days.
3015 Add #error catchall just in case.
3017 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3018 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3019 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
3020 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.

3038 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
3040 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
3041 This will cause a production Emacs to dump core instead of
3044 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3046 * frame.c (make_frame): Do not set window's buffer to t.
3047 * window.c (Fsplit_window_internal): Likewise. Previously it was
3048 used to indicate that the window is being set up. Now we use
3049 set_window_buffer for all new windows, so the condition in ...
3050 (Fset_window_buffer): ... is always true and can be removed.
3052 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3054 Convenient macro to check whether the buffer is hidden.
3055 * buffer.h (BUFFER_HIDDEN_P): New macro.
3056 * frame.c (make_frame): Use it. Adjust comment.
3057 * buffer.c (candidate_buffer): New function.

3062 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
3063 if the child process is still running. Instead, exit the wait
3064 loop and return zero. (Bug#13086)
3066 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3068 * frame.h (x_char_width, x_char_height): Remove prototypes.

3079 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
3081 Fix a recently-introduced delete-process race condition.
3082 * callproc.c, process.h (record_kill_process):
3083 New function, containing part of the old call_process_kill.
3084 (call_process_kill): Use it.
3085 This does not change call_process_kill's behavior.
3086 * process.c (Fdelete_process): Use record_kill_process to fix a
3087 race condition that could cause Emacs to lose track of a child.
3089 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3091 Avoid code duplication between prev_frame and next_frame.
3092 * frame.c (candidate_frame): New function. Add comment.
3093 (prev_frame, next_frame): Use it. Adjust comment.
3095 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3097 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3098 fails, signal an error instead of continuing with an empty
3100 Encode expanded temp file pattern before passing it to mkstemp or
3103 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3104 Encode the file name before passing it to dostounix_filename, in
3105 case it will downcase it (under w32-downcase-file-names).
3108 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3110 Minor call-process cleanups.
3111 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3112 at the same time as other platforms, to simplify analysis.
3113 No need for fd0_volatile since we have synch_process_fd.
3114 Avoid needless emacs_close; arg is always negative.
3116 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3118 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3121 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3123 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3124 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer

3129 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
3130 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3131 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3132 members to a bitfields.
3134 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3136 Don't let call-process be a zombie factory (Bug#12980).
3137 Fixing this bug required some cleanup of the signal-handling code.
3138 As a side effect, this change also fixes a longstanding rare race
3139 condition whereby Emacs could mistakenly kill unrelated processes,
3140 and it fixes a bug where a second C-g does not kill a recalcitrant
3141 synchronous process in GNU/Linux and similar platforms.
3142 The patch should also fix the last vestiges of Bug#9488,
3143 a bug which has mostly been fixed on the trunk by other changes.
3144 * callproc.c, process.h (synch_process_alive, synch_process_death)
3145 (synch_process_termsig, sync_process_retcode):
3146 Remove. All uses removed, to simplify analysis and so that
3147 less consing is done inside critical sections.
3148 * callproc.c (call_process_exited): Remove. All uses replaced
3149 with !synch_process_pid.
3150 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3151 These take the role of what used to be in unwind-protect arg.
3153 (block_child_signal, unblock_child_signal):
3154 New functions, to avoid races that could kill innocent-victim processes.
3155 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3156 (call_process_kill): Record killed processes as deleted, so that
3157 zombies do not clutter up the system. Do this inside a critical
3158 section, to avoid a race that would allow the clutter.
3159 (call_process_cleanup): Fix code so that the second C-g works again
3160 on common platforms such as GNU/Linux.
3161 (Fcall_process): Create the child process in a critical section,
3162 to fix a race condition. If creating an asynchronous process,
3163 record it as deleted so that zombies do not clutter up the system.
3164 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3165 light of these changes. Omit unnecessary call to emacs_close
3166 before failure, as the unwind-protect code does that.
3167 * callproc.c (call_process_cleanup):
3168 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3169 * process.c (record_deleted_pid): New function, containing
3170 code refactored out of Fdelete_process.
3171 (Fdelete_process): Use it.
3172 (process_status_retrieved): Remove. All callers changed to use
3173 child_status_change.
3174 (record_child_status_change): Remove, folding its contents into ...
3175 (handle_child_signal): ... this signal handler. Now, this
3176 function is purely a handler for SIGCHLD, and is not called after
3177 a synchronous waitpid returns; the synchronous code is moved to
3178 wait_for_termination. There is no need to worry about reaping
3179 more than one child now.
3180 * sysdep.c (get_child_status, child_status_changed): New functions.
3181 (wait_for_termination): Now takes int * status and bool
3182 interruptible arguments, too. Do not record child status change;
3183 that's now the caller's responsibility. All callers changed.
3184 Reimplement in terms of get_child_status.
3185 (wait_for_termination_1, interruptible_wait_for_termination):
3186 Remove. All callers changed to use wait_for_termination.
3187 * syswait.h: Include <stdbool.h>, for bool.
3188 (record_child_status_change, interruptible_wait_for_termination):
3190 (record_deleted_pid, child_status_changed): New decls.
3191 (wait_for_termination): Adjust to API changes noted above.
3193 * bytecode.c, lisp.h (Qbytecode): Remove.
3194 No longer needed after 2012-11-20 interactive-p changes.
3196 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3198 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3199 the scroll margin, move point outside the margin. (Bug#13055)
3201 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3203 * gtkutil.c (my_log_handler): New function.
3204 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3206 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3208 * lisp.h (modify_region): Rename to...
3209 (modify_region_1): ...new prototype.
3210 * textprop.c (modify_region): Now static. Adjust users.
3211 * insdel.c (modify_region): Rename to...
3212 (modify_region_1): ...new function to work with current buffer.
3213 Adjust comment and users. Use true and false for booleans.
3215 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3217 * alloc.c (free_save_value): New function.
3218 (safe_alloca_unwind): Use it.
3219 * lisp.h (free_save_value): New prototype.
3220 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3222 (save_excursion_restore): Adjust to match saved data structure.
3223 Use free_save_value to offload some work from GC. Drop obsolete
3226 2012-12-03 Chong Yidong <cyd@gnu.org>
3228 * fileio.c (Vauto_save_list_file_name): Doc fix.
3230 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3232 * w32fns.c: Remove prototype of atof.
3233 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3235 (file_dialog_callback): Make it UINT_PTR.
3237 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3240 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3241 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3244 2012-12-03 Glenn Morris <rgm@gnu.org>
3246 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3248 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3250 Fix xpalloc confusion after memory is exhausted.
3251 * alloc.c (xpalloc): Comment fix.
3252 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3253 and signals an error, do not clear charset_table_size, as
3254 charset_table is still valid.
3255 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3257 Use execve to avoid need to munge environ (Bug#13054).
3258 * callproc.c (Fcall_process):
3259 * process.c (create_process):
3260 Don't save and restore environ; no longer needed.
3261 * callproc.c (child_setup):
3262 Use execve, not execvp, to preserve environ.
3264 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3266 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3268 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3270 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3271 display for sliced images (Bug#10500).
3273 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3275 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3277 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3278 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3280 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3282 * xdisp.c (window_outdated): Remove eassert since it hits
3283 some suspicious corner cases (see Bug#13007 and Bug#13012).
3284 (mode_line_update_needed): New function.
3285 (redisplay_internal, redisplay_window): Use it.
3286 (ensure_selected_frame): New function.
3287 (redisplay_internal, unwind_redisplay): Use it.
3288 (redisplay_internal): Move comment about buffer_shared...
3289 (buffer_shared_and_changed): ...near to its real use.
3291 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3293 * callproc.c (Fcall_process): Don't misreport vfork failure.
3295 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3297 * callproc.c (Fcall_process): Fix vfork portability problems.
3298 Do not assume that fd[0], count, filefd, and save_environ survive
3299 vfork. Fix bug whereby wrong errno value could be reported for
3300 pipe failure. Some minor cleanups, too, as follows. Move buf and
3301 bufsize to the context where they're needed. Change new_argv to
3302 be of type char **, as this is more convenient and avoids casts.
3303 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3304 Now local constants, not macros.
3306 2012-11-18 Kenichi Handa <handa@gnu.org>
3308 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3309 for the variable "f".
3311 2012-11-13 Kenichi Handa <handa@gnu.org>
3313 * font.c (font_unparse_xlfd): Exclude special characters from the
3314 generating XLFD name.
3316 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
3318 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
3319 * dired.c (stat_uname, stat_gname):
3320 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
3322 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

3328 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
3329 * lread.c (readbyte_from_file): Assume EINTR is defined.
3330 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3331 Assume EIO and EAGAIN are defined.
3332 * unexcoff.c (write_segment): Assume EFAULT is defined.
3334 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3336 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
3339 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
3340 highlighting on the frame was cleared. Prevents assertion
3341 violations when repeatedly clicking on the "Top" link of the
3342 "bread-crumbs" in Info buffers.
3344 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
3346 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.

3350 * keyboard.c (HAVE_MOUSE):
3351 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
3352 were always defined.
3354 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3356 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3357 between bpos_covered and bpos_max. This fixes cursor display when
3358 several display strings follow each other.
3360 * .gdbinit (pgx): If the glyph's object is a string, display the
3361 pointer to string data, rather than the value of the string object
3362 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3364 * indent.c (Fvertical_motion): If the starting position is covered
3365 by a display string, return to one position before that, to avoid
3366 overshooting it inside move_it_to. (Bug#12930)
3368 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3370 * frame.h (struct frame): Remove display_preempted member
3371 since all users are dead long ago.
3372 * nsterm.h (struct x_output): Use the only dummy member.
3373 * w32menu.c (pending_menu_activation): Remove since not
3375 (set_frame_menubar): Adjust user.
3376 * w32term.h (struct x_output): Drop outdated #if 0 code.
3377 (struct w32_output): Use bitfields for explicit_parent,
3378 asked_for_visible and menubar_active members.
3379 Drop unused pending_menu_activation member.
3380 * xterm.h (struct x_output): Drop outdated #if 0 code.
3381 Use bitfields for explicit_parent, asked_for_visible,
3382 has_been_visible and net_wm_state_hidden_seen members.
3384 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3386 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3387 of a literal "/". (Bug#12955)
3388 (gl-stamp): Invoke fc.exe directly, not through cmd.
3390 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
3392 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
3393 * dired.c: Assume HAVE_DIRENT_H.
3394 (NAMLEN): Remove, replacing with ...
3395 (dirent_namelen): New function. All uses changed. Use the GNU macro
3396 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3397 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3398 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3399 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3401 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3402 * ndir.h: Rename to ../nt/inc/dirent.h.
3403 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3404 Do not include <dirent.h>; no longer needed.
3405 * w32.c: Include <dirent.h> rather than "ndir.h".
3407 2012-11-23 Chong Yidong <cyd@gnu.org>
3409 * xftfont.c (xftfont_open): Remove duplicate assignment.
3411 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3413 * alloc.c (Fgarbage_collect): Unblock input after clearing
3414 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3415 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3416 * msdos.c (IT_frame_up_to_date): Use it here...
3417 * w32term.c (w32_frame_up_to_date): ...here...
3418 * xterm.c (XTframe_up_to_date): ...and here...
3419 * nsterm.m (ns_frame_up_to_date): ...but not here.
3420 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3422 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3423 Do not check whether GC is in progress.
3425 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3427 * xdisp.c (window_buffer_changed): New function.
3428 (update_menu_bar, update_tool_bar): Use it to
3429 simplify large 'if' statements.
3430 (redisplay_internal): Generalize commonly used
3431 'tail' and 'frame' local variables.
3433 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3435 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3436 with Windows system header.
3438 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3440 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3441 * alloc.c: Assume unistd.h exists.
3442 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
3443 * sysdep.c (get_current_dir_name): Assume getcwd exists.
3444 (getwd) [USG]: Remove; no longer needed.
3445 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3446 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3447 * w32.h (getcwd): Remove decl.
3449 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
3451 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
3452 Make it set selected_window as well.
3453 (update_tool_bar): Use it.
3455 2012-11-21 Ken Brown <kbrown@cornell.edu>
3457 * emacs.c (main): Set the G_SLICE environment variable for all
3458 Cygwin builds, not just GTK builds. See
3459 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3461 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3463 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3464 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3465 Define for the MSVC compiler.
3467 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3469 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3470 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3471 dostounix_filename. Prevents crashes down the road, because
3472 dostounix_filename assumes it gets a unibyte string.
3473 Reported by Michel de Ruiter <michel@sentient.nl>, see
3474 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
3476 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

3482 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
3483 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
3484 Test NILP rather than Qunbound.
3485 (Ffmakunbound): Set to Qnil.
3486 (Fsymbol_function): Never signal an error.
3487 (Finteractive_form): Ignore Qunbound.
3489 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3491 * eval.c (interactive_p): Remove no-longer-used decl.
3493 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3495 * xdisp.c (buffer_shared): Adjust comment.
3496 (buffer_shared_and_changed): New function.
3497 (prepare_menu_bars, redisplay_internal): Use it to
3498 decide whether all windows or frames should be updated.
3499 (window_outdated): New function.
3500 (text_outside_line_unchanged_p, redisplay_window): Use it.
3501 (redisplay_internal): Likewise. Fix indentation.
3503 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3505 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3506 (syms_of_eval): Remove corresponding defsubr.
3507 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3509 2012-11-19 Daniel Colascione <dancol@dancol.org>
3511 * w32fns.c (Fx_file_dialog):
3512 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3513 cygwin_convert_file_name*.
3515 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3516 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3518 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3520 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3522 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3524 * w32select.c: Include w32common.h before w32term.h, so that
3525 windows.h gets included before w32term.h uses some of its
3526 features, see below.
3528 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3530 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3532 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3534 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3536 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3537 (ns_select): Return at once if events are held (Bug#12834).
3539 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3541 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3542 Needed following 2012-10-20 change. (Bug#12902)
3544 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3546 * w32proc.c (waitpid): Remove unused label get_result.
3548 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3550 * makefile.w32-in (SYSWAIT_H): New macro.
3551 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3552 ($(BLD)/sysdep.$(O)): Update dependencies.
3554 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3556 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3557 * callproc.c (relocate_fd): Assume F_DUPFD.
3558 * emacs.c, term.c (O_RDWR): Remove.
3559 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3560 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3561 * nsterm.m: Assume <fcntl.h> exists.
3562 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3563 (create_pty, Fmake_network_process, server_accept_connection)
3564 (wait_reading_process_output, init_process_emacs):
3566 (wait_reading_process_output): Put in a special case for WINDOWSNT
3567 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3568 It's not clear this is needed, but it's a more-conservative change.
3569 (create_process): Assume FD_CLOEXEC.
3570 (create_process, create_pty): Assume O_NOCTTY.
3571 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3572 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3573 Omit if not DOS_NT, since F_GETFL is not defined there.
3574 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3575 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3577 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3578 lack it, since gnulib guarantees this.
3579 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3581 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3583 * w32.c (faccessat): Pretend that directories have the execute bit
3584 set. Emacs expects that, e.g., in files.el:cd-absolute.
3586 * w32proc.c (create_child): Don't clip the PID of the child
3587 process to fit into an Emacs integer, as this is no longer a
3589 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3590 reaping only the process specified by PID argument, if that is
3591 positive. Use PID instead of dead_child to know which process to
3592 reap. Wait for the child to die only if WNOHANG is not in
3594 (sys_select): Don't set dead_child.
3596 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3597 as it is no longer needed.
3599 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3601 (record_child_status_change): Remove the setting of
3602 record_at_most_one_child for the !WNOHANG case.
3604 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3606 Fix problems in ns port found by static checking.
3607 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3608 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3609 not to process group.
3610 (ns_select): Use emacs_write, not write, as that's more robust
3611 in the presence of signals.
3612 (fd_handler:): Check for read errors.
3614 2012-11-16 Glenn Morris <rgm@gnu.org>
3616 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3618 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3620 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3622 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3624 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3625 use the same value of thread handle.
3626 (start_timer_thread): If the timer thread exited (due to error),
3627 clean up by closing the two handles it used. Duplicate the caller
3628 thread's handle here, so it gets duplicated only once, when
3629 launching the timer thread. Set priority of the timer thread, not
3631 (getitimer): Don't duplicate the caller thread's handle here.
3634 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3636 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3639 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3641 Remove no-longer-used pty_max_bytes variable.
3642 * process.c (pty_max_bytes): Remove; unused.
3643 (send_process): Do not set it.
3645 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3647 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3648 Update dependencies.
3650 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3652 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3653 This follows up on the 2012-09-29 patch that removed indirection
3654 for the 'function' field. Reported by Sergey Vinokurov in
3655 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3657 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3659 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3660 different name, as the MS runtime does not have such a function,
3661 and probably never will.) All callers changed. Ignore DIRFD
3662 value if PATH is an absolute file name, to match Posix spec
3663 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3666 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3668 * xdisp.c (echo_area_display, redisplay_internal):
3669 Omit redundant check whether frame_garbaged is set.
3671 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3673 Use faccessat, not access, when checking file permissions (Bug#12632).
3674 This fixes a bug that has been present in Emacs since its creation.
3675 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3676 which must set some sort of record. (Torek's bug report was against
3677 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3678 same common flaw.) See Torek's Usenet posting
3679 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3680 Posted: Fri Apr 8 14:18:56 1983.
3681 * Makefile.in (LIB_EACCESS): New macro.
3683 * callproc.c (init_callproc):
3684 * charset.c (init_charset):
3685 * fileio.c (check_existing, check_executable, check_writable)
3687 * lread.c (openp, load_path_check):
3688 * process.c (allocate_pty):
3690 Use effective UID when checking permissions, not real UID.
3691 * callproc.c (init_callproc):
3692 * charset.c (init_charset):
3693 * lread.c (load_path_check, init_lread):
3694 Test whether directories are accessible, not merely whether they exist.
3695 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3696 * fileio.c (check_existing, check_executable, check_writable)
3698 Use symbolic names instead of integers for the flags, as they're
3700 (check_writable): New arg AMODE. All uses changed.
3701 Set errno on failure.
3702 (Ffile_readable_p): Use faccessat, not stat + open + close.
3703 (Ffile_writable_p): No need to call check_existing + check_writable.
3704 Just call check_writable and then look at errno. This saves a syscall.
3705 dir should never be nil; replace an unnecessary runtime check
3706 with an eassert. When checking the parent directory of a nonexistent
3707 file, check that the directory is searchable as well as writable, as
3708 we can't create files in unsearchable directories.
3709 (file_directory_p): New function, which uses 'stat' on most platforms
3710 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3711 (Ffile_directory_p, Fset_file_times): Use it.
3712 (file_accessible_directory_p): New function, which uses a single
3713 syscall for efficiency.
3714 (Ffile_accessible_directory_p): Use it.
3715 * xrdb.c (file_p): Use file_directory_p.
3716 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3717 * lread.c (openp): When opening a file, use fstat rather than
3718 stat, as that avoids a permissions race. When not opening a file,
3719 use file_directory_p rather than stat.
3720 (dir_warning): First arg is now a usage string, not a format.
3721 Use errno. All uses changed.
3722 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3723 that merely introduced a race.
3724 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3725 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3726 and similarly for the other O_* flags.
3727 * w32.c (sys_faccessat): Rename from sys_access and switch to
3728 faccessat's API. All uses changed.
3729 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3730 (magic_db): Rename from magic_file_p.
3731 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3732 char *, so that we don't have to test for file existence
3733 separately from opening the file for reading. This removes a race
3734 fixes a permission-checking problem, and simplifies the code.
3736 (file_p): Remove; no longer needed.
3738 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3740 Omit glyphs initialization at startup.

3748 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3750 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3751 passed to pint2str and pint2hrstr to be at most the size of the
3752 frame's decode_mode_spec_buffer. This avoids crashes with very
3753 large values of FIELD_WIDTH argument to decode_mode_spec.
3756 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3758 Fix a race with verify-visited-file-modtime (Bug#12863).
3759 Since at least 1991 Emacs has ignored an mtime difference of no
3760 more than one second, but my guess is that this was to work around
3761 file system bugs that were fixed long ago. Since the race is
3762 causing problems now, let's remove that code.
3763 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3764 whose time stamp is off by no more than a second. Insist that the
3765 file time stamps match exactly.
3767 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3769 * frame.h (struct frame): Convert external_tool_bar member to
3770 1-bit unsigned bitfield.

3772 all users are long dead. Adjust comment on mouse_position_hook.
3774 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3776 Simplify by using FOR_EACH_FRAME here and there.
3777 * frame.c (next_frame, prev_frame, other_visible_frames)

3784 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3785 * xmenu.c (menubar_id_to_frame): Likewise.
3786 * xselect.c (frame_for_x_selection): Likewise.
3787 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3788 (x_window_to_menu_bar): Likewise.
3789 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3791 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3793 * data.c (Qdefalias_fset_function): Now static.
3795 Another tweak to vectorlike_header change.

3797 Remove, and replace all uses with ...
3798 (next_in_free_list, set_next_in_free_list):
3799 New functions, which respect C's aliasing rules better.
3801 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3803 * window.c (list4i): Rename from 'quad'. All uses changed.
3804 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3806 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3808 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3809 warning about mixing declarations and code in ISO C90.
3811 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3813 * window.c (Fsplit_window_internal): Set combination limit of
3814 new parent window to t iff Vwindow_combination_limit is t;
3815 fixing a regression introduced with the change from 2012-09-22.
3816 (Fset_window_combination_limit): Fix doc-string.
3818 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3820 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3821 amount when the scroll margins are too large. When scrolling
3822 backwards in the buffer, give up if cannot reach point or the
3823 scroll margin within a reasonable number of screen lines.
3824 Fixes point position in window under scroll-up/down-aggressively when
3825 point is positioned many lines beyond the window top/bottom.
3828 * ralloc.c (relinquish): If real_morecore fails to return memory
3829 to the system, don't crash; instead, leave the last heap
3830 unchanged and return. (Bug#12774)
3832 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3834 * lisp.h (AUTOLOADP): New macro.

3839 (Finteractive_form): Simplify.
3840 (Fquo): Don't insist on having at least 2 arguments.
3841 (Qdefalias_fset_function): New var.
3843 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3845 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

3851 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3853 Fix recently introduced crash on MS-Windows (Bug#12839).
3854 * w32term.h (struct scroll_bar): Use convenient header.
3855 (SCROLL_BAR_VEC_SIZE): Remove.
3856 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3858 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3860 Tweak last vectorlike_header change.
3861 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3862 vectorlike object on the free list. This is introduced to avoid
3863 some (but not all) pointer casting and aliasing problems, see
3864 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3865 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

3869 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3871 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3872 been removed, so remove them here also.
3874 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3876 * doc.c (Fdocumentation): Handle new property
3877 dynamic-docstring-function to replace the old ad-advice-info.
3879 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3881 * fns.c (Qeql, hashtest_eq): Now static.
3883 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3885 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3886 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3887 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

3897 special hash function containing a comparison that always yields 1.
3899 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3901 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3902 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3903 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3906 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3908 * image.c (xpm_make_color_table_h): Fix compiler error because
3909 make_hash_table changed.

3913 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3915 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3917 Use ad-hoc comparison function for the profiler's hash-tables.
3918 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3919 (make_log): Use them.
3920 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3921 call Fequal any more.

3931 (hash_lookup, hash_remove_from_table): Move assertion checking of
3932 hashfn result here. Check hash-equality before calling cmpfn.

3972 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3973 (large_vectors): Change type to struct large_vector.
3974 (allocate_vector_from_block): Simplify.

3997 * keyboard.c (event_to_kboard): Do not dereference
3998 frame_or_window field of SELECTION_REQUEST_EVENT

4002 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4004 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4005 such as Scroll Lock, if the respective keys are treated as
4006 function keys, not as modifiers. This avoids destroying non-ASCII
4007 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4009 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4011 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4013 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4015 Restore some duplicate definitions (Bug#12814).
4016 This undoes part of the 2012-11-03 changes. Some people build
4017 with plain -g rather than with -g3, and they need the duplicate
4018 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4019 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4020 Define as macros, as well as as enums or as constants.

4024 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4025 to keypad keys (Bug#12816).
4027 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4029 Minor adjustments of recently-changed frame functions.
4030 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4031 known to be a frame (we're in the FRAMEP branch).
4032 * lisp.h (Qframep): Remove decl. frame.h declares this.
4033 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4034 since they're meant for Lisp fixnum values.
4036 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4038 * window.c (Fwindow_combination_limit): Revert to the only
4039 required argument and adjust docstring as suggested in
4040 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4041 by Martin Rudalics <rudalics@gmx.at>.

4087 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4088 (Fwindow_combination_limit): Allow zero number of arguments.
4090 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4092 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4094 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4095 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4096 file descriptor 2 for standard error. (Bug#12805)
4098 2012-11-05 Chong Yidong <cyd@gnu.org>
4100 * process.c (wait_reading_process_output): Revert previous change.
4102 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4104 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4105 This removes code that has been obsolete since around 1990.
4106 * callproc.c (Fcall_process):
4108 * process.c (create_process):
4109 * term.c (dissociate_if_controlling_tty):
4110 Assume setsid exists.
4111 * callproc.c (child_setup): Assume setpgid exists and behaves as
4112 per POSIX.1-1988 or later.
4113 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4114 * emacs.c (shut_down_emacs):

4127 Do not assume that __fpending's result fits in int.
4129 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4131 Remove EMACS_OUTQSIZE+sleep hack.
4132 * dispnew.c (update_frame_1): Remove hack for terminals slower
4133 than 2400 bps, which throttled Emacs by having it sleep.
4134 This code hasn't worked since at least 2007, when the multi-tty stuff
4135 was added, and anyway those old terminals are long dead.
4136 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4137 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4139 Fix data-loss with --version (Bug#9574).
4140 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4141 as we can't assume that emacs_strerror is initialized, and strerror
4142 is good enough here.
4143 (main): Invoke atexit earlier, to catch earlier instances of
4144 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4146 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4148 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4149 (keyDown): Remap keypad keys to X11 virtual key codes.
4151 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4153 Fix data-loss with --batch (Bug#9574).
4154 * emacs.c: Include <close-stream.h>.
4155 (close_output_streams): New function.
4156 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4157 and handles errors appropriately.
4158 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4161 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4162 The symptom is a diagnostic "GLib-WARNING **: In call to
4163 g_spawn_sync(), exit status of a child process was requested but
4164 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4165 waitpid(), so exit status can't be returned." The diagnostic
4166 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4167 The real bug is a race condition between Emacs and glib: Emacs
4168 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4169 so that glib can't find it. Work around the bug by invoking
4170 waitpid only on subprocesses that Emacs itself creates.
4171 * process.c (create_process, record_child_status_change):
4172 Don't use special value -1 in pid field, as the caller now must
4173 know the pid rather than having the callee infer it.
4174 The inference was sometimes incorrect anyway, due to another race.
4175 (create_process): Set new 'alive' member if child is created.
4176 (process_status_retrieved): New function.
4177 (record_child_status_change): Use it.
4178 Accept negative 1st argument, which means to wait for the
4179 processes that Emacs already knows about. Move special-case code
4180 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4181 processes that have already been waited for, by testing and
4182 clearing new 'alive' member.
4183 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4184 now does this internally.
4185 (handle_child_signal): Let record_child_status_change do all
4186 the work, since we do not want to reap all exited child processes,
4187 only the child processes that Emacs itself created.
4188 * process.h (Lisp_Process): New boolean member 'alive'.
4190 Omit duplicate definitions no longer needed with gcc -g3.
4191 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4192 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4193 Define only as macros. There's no longer any need to also define
4194 these symbols as enums or as constants, since we now assume
4195 gcc -g3 when debugging.
4197 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4199 * lisp.mk: Adjust comments to the fact that term/internal is now
4200 loaded from loadup.el.
4202 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4203 (msdos_fatal_signal): New function.
4204 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4207 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4208 for GCC versions before 4.
4209 (emacs_raise): Define to call msdos_fatal_signal.
4211 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4212 iterator when starting in the middle of a display or overlay
4215 2012-11-03 Chong Yidong <cyd@gnu.org>
4217 * process.c (wait_reading_process_output): Clean up the last
4220 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4222 * process.c (wait_reading_process_output): Avoid a race condition
4223 with SIGIO delivery (Bug#11536).
4225 2012-11-03 Chong Yidong <cyd@gnu.org>
4227 * buffer.c (cursor_type): Untabify docstring.
4229 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4231 * frame.h (struct frame): Drop can_have_scroll_bars member
4232 which is meaningless for a long time. Adjust comments.
4233 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4234 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4236 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4238 * window.c (decode_next_window_args): Update window arg after
4239 calling decode_live_window and so fix crash reported at
4240 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4241 by Juanma Barranquero <lekktu@gmail.com>.
4242 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4243 * font.c (Ffont_at): Likewise.
4245 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4247 * widget.c (resize_cb): New function.
4248 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4249 (EmacsFrameResize): Check if all is up to date before changing frame
4252 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4254 Implement backtrace output for fatal errors on MS-Windows.
4255 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4256 (BACKTRACE_LIMIT_MAX): New macro.
4257 (w32_backtrace): New function.
4258 (emacs_abort): Use w32_backtrace when the user chooses not to
4259 attach a debugger. Update the text of the abort dialog.
4261 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4263 Window-related stuff cleanup here and there.
4264 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4265 Use decode_any_window.
4266 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4267 * xdisp.c (Fformat_mode_line): Likewise.
4268 * font.c (Ffont_at): Use decode_live_window.
4269 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4270 * window.c (decode_next_window_args): Likewise.
4271 (decode_any_window): Remove static.
4272 * window.h (decode_any_window): Add prototype.
4273 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4274 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4277 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4279 Remove pad from struct input_event.
4280 * termhooks.h (struct input_event): Remove padding field.
4282 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4283 member is never cons for a long time. Adjust comment.
4284 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4285 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4286 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4287 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4289 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4291 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4293 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4295 Fix crash when using Emacs as commit editor for git (Bug#12697).
4296 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4297 and it is configured in conf_post.h.
4298 (Fcall_process): Don't invoke both setsid and setpgid; the former
4299 is enough, if it exists.
4300 * callproc.c (Fcall_process, child_setup):
4301 * process.c (create_process): Use setpgid.
4302 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4304 * dispnew.c (init_display): Initialize the foreground group
4305 if we are running a tty display.
4306 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4307 * lisp.h (init_foreground_group): New decl.
4308 * sysdep.c (inherited_pgroup): New static var.
4309 (init_foreground_group, tcsetpgrp_without_stopping)
4310 (narrow_foreground_group, widen_foreground_group): New functions.
4311 (init_sys_modes): Narrow foreground group.
4312 (reset_sys_modes): Widen foreground group.
4314 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4316 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4318 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4320 * minibuf.c (read_minibuf): Restore current buffer since
4321 choose_minibuf_frame calling Fset_frame_selected_window may
4322 change it (Bug#12766).
4324 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4326 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4328 2012-10-30 Kenichi Handa <handa@gnu.org>
4330 * font.c (Ffont_at): If WINDOW is specified and it is not
4331 displaying the current buffer, signal an error.
4333 2012-10-29 Daniel Colascione <dancol@dancol.org>
4335 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4336 In preparation for fixing bug#12739, move these functions from
4339 * coding.h, coding.c: ... to here, and compile them only when
4340 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4341 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4343 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4345 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4346 (timer_loop, getitimer, setitimer): Use it instead of
4347 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4349 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4352 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4354 * nsterm.m (NO_APPDEFINED_DATA): New define.
4355 (last_appdefined_event_data): New variable
4356 (last_appdefined_event): Remove.
4357 (ns_select): Initialize t from last_appdefined_event_data instead
4358 of [last_appdefined_event data1].
4359 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4360 remove last_appdefined_event (Bug#12698).
4362 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4364 * frame.c (x_set_font): Catch internal error.
4366 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4368 Avoid overflow in w32 implementation of interval timers.
4369 When possible, for ITIMER_PROF count only times the main thread
4371 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4372 'volatile ULONGLONG' types. All the other data which was
4373 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4374 (GetThreadTimes_Proc): New typedef.
4375 (w32_get_timer_time): New function, returns a suitable time value
4377 (timer_loop): Enter critical section when accessing ULONGLONG
4378 values of the itimer_data struct, as these accesses are no longer
4379 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4380 Remove unused variable.
4381 (init_timers): Initialize s_pfn_Get_Thread_Times.
4382 (start_timer_thread): Don't assign itimer->caller_thread here.
4383 (getitimer): Assign itimer->caller_thread here.
4384 (setitimer): Always call getitimer to get the value of ticks_now.
4385 (sys_spawnve): Avoid compiler warning about format mismatch.
4387 2012-10-26 Eli Zaretskii <eliz@gnu.org>
4389 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4390 mouse movement events if the menu bar is active. This avoids
4391 producing a busy "hour-glass" cursor by Windows if the mouse
4392 pointer is positioned over a tooltip shown for some menu item.
4394 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4396 Don't assume process IDs fit in int.
4397 * emacs.c (shut_down_emacs) [!DOS_NT]:
4398 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4399 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4400 Use pid_t, not int, to store process IDs, as 'int'
4401 is not wide enough on a few platforms (e.g., AIX and IRIX).
4403 2012-10-23 Kenichi Handa <handa@gnu.org>
4405 The following change is to make face-font-rescale-alist work
4406 correctly for non-ASCII fonts.
4408 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4409 (font_open_for_lface): Handle Vface_font_rescale_alist.
4411 2012-10-23 Chong Yidong <cyd@gnu.org>
4413 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4415 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
4417 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
4419 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
4421 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
4424 2012-10-21 Glenn Morris <rgm@gnu.org>
4426 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4428 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4430 Port to OpenBSD 5.1.
4431 * frame.c (Fmouse_position, Fmouse_pixel_position):
4432 * xdisp.c (produce_stretch_glyph):
4433 Declare local vars only when they're needed.
4434 This is clearer and avoids a warning on OpenBSD about unused vars.
4435 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
4436 This is safer, and avoids OpenBSD warnings about unused vars.
4437 * keyboard.c (record_menu_key): Remove unnecessary decl.
4438 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4439 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4440 as our definition clashes with OpenBSD's.
4441 * xfaces.c (load_face_colors, check_lface_attrs)
4442 (get_lface_attributes_no_remap, get_lface_attributes)
4443 (lface_fully_specified_p, x_supports_face_attributes_p)
4444 (tty_supports_face_attributes_p, face_fontset, realize_face)
4445 (realize_x_face, realize_tty_face):
4446 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4447 merely Lisp_Object *. This is more informative and avoids
4448 a warning on OpenBSD about accessing beyond an object's size.
4450 2012-10-20 Chong Yidong <cyd@gnu.org>
4452 * lread.c (Fload): Doc fix (Bug#12592).
4454 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
4456 * font.c (Ffont_at): Fix previous change.
4458 2012-10-19 Eli Zaretskii <eliz@gnu.org>
4460 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
4461 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
4464 * alloc.c (NSTATICS): Decrease to 0x800.
4466 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

4471 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
4473 * nsterm.m (ns_select): Check writefds before call to
4474 FD_ISSET (Bug#12668).
4476 2012-10-18 Daniel Colascione <dancol@dancol.org>
4478 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4479 (staticpro): If we run out of staticpro slots, die with an
4480 informative error instead of just calling emacs_abort.
4482 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4484 Fix two flaws reported by Dmitry Antipov.
4485 * window.c (Ftemp_output_buffer_show): Remove.
4486 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
4487 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.

4495 ($(BLD)/fileio.$(O)):
4496 ($(BLD)/dispnew.$(O)): Update dependencies.
4498 * w32term.h (w32_initialize_display_info, initialize_w32_display):
4501 * w32proc.c: Include ctype.h.

4505 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
4506 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
4507 (sys_link): Add prototypes.
4509 * w32.c: Include w32select.h.
4510 (sys_access, e_malloc, sys_select): Add prototypes.
4511 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
4513 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
4515 * unexw32.c: Include lisp.h and w32.h.
4517 * term.c [WINDOWSNT]: Include w32term.h.
4519 * process.c [WINDOWSNT]: Add prototype of sys_select.
4521 * fileio.c [WINDOWSNT]: Include w32.h.
4523 * dispnew.c [WINDOWSNT]: Include w32.h.
4525 * cygw32.c (Fcygwin_convert_path_to_windows)
4526 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
4527 Lisp_Object values. (Bug#12661)
4529 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
4530 to Lisp_Object. (Bug#12661)
4532 2012-10-17 Kenichi Handa <handa@gnu.org>

4542 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
4544 Do not verify indirection counters of killed buffers (Bug#12579).
4545 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
4546 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.

4550 * alloc.c (Fmake_byte_code): Fix typo in comment.
4551 * print.c (print_interval): Define as static to match prototype.

4566 2012-10-15 Martin Rudalics <rudalics@gmx.at>
4568 * window.c (Fwindow_end): Rewrite check whether cached position
4569 can be used (Bug#12600).
4570 (resize_frame_windows, grow_mini_window, shrink_mini_window):

4573 2012-10-15 Daniel Colascione <dancol@dancol.org>
4575 * dbusbind.c: Fix cygw32 build break when compiling with dbus
4576 enabled by undefining the symbol "interface", which the platform
4577 headers define to something incompatible.
4579 2012-10-14 Daniel Colascione <dancol@dancol.org>
4581 * image.c (init_tiff_functions, init_imagemagick_functions)

4598 2012-10-13 Andreas Schwab <schwab@linux-m68k.org>
4600 * fileio.c: Formatting fixes.
4602 2012-10-13 Paul Eggert <eggert@cs.ucla.edu>
4604 Fix some stat-related races.
4605 * fileio.c (Fwrite_region): Avoid race condition if a file is
4606 removed or renamed by some other process immediately after Emacs
4607 writes it but before Emacs stats it. Do not assume that stat (or
4609 * image.c (slurp_file): Resolve the file name with fopen + fstat
4610 rather than stat + fopen.
4611 (pbm_read_file) [0]: Remove unused code with stat race.
4612 * process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]:

4627 (setPosition:portion:whole:): Send SIGIO to ourselves if apploopnr
4628 is zero (Bug#12384).
4630 2012-10-12 Juanma Barranquero <lekktu@gmail.com>

4636 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
4638 * fileio.c (check_existing): New function.
4639 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
4640 instead of calling 'stat', when what's needed is to check whether
4641 a file exists. This avoids expensive system calls on MS-Windows.
4644 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
4646 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
4647 determine whether a file exists and is not a directory.
4649 * lisp.h (check_existing): Add prototype.
4651 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
4653 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

4683 Use bool for booleans.
4684 * lread.c (safe_to_load_version): Rename from safe_to_load_p,
4685 as it's not a predicate. All uses changed. Omit unnecessary

4690 * editfns.c (save_excursion_save): Use nil if mark points to nowhere.
4691 (save_excursion_restore): Do not restore mark if it was not saved.
4693 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
4695 * marker.c (cached_modiff): EMACS_INT, not int.
4697 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
4698 instead of having a wrong decl.

4736 (detect_input_pending_run_timers):
4737 * process.c (wait_reading_process_output):
4738 Use unsigned for counter where wraparound-on-overflow is desired,
4739 since unsigned is guaranteed to have that behavior and signed is not.
4740 (read_char): Use ptrdiff_t for string length.
4741 (get_input_pending): Remove first argument, since it was always
4742 the same pointer-to-int (now pointer-to-boolean) &input_pending,
4743 and behave as if it had that value. Return new value of
4744 input_pending. All callers changed.
4745 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4746 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
4748 * keymap.c (push_key_description): Omit last arg, which was always 1.
4749 All callers changed.
4751 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
4753 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

4769 Don't include termopts.h.
4771 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
4773 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
4775 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4777 * commands.h (immediate_quit): Remove duplicate decl.
4779 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
4781 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
4783 (nsfont_open): Remove setting of Vfonts_in_cache.
4784 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
4786 2012-10-09 Eli Zaretskii <eliz@gnu.org>
4788 * w32fns.c (w32_last_error): Change the return value to DWORD, to
4789 match what GetLastError returns. Explain why the function is
4792 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4793 'is_tooltip_frame', to avoid confusion with its global namesake.
4795 2012-10-08 Daniel Colascione <dancol@dancol.org>
4797 * xdisp.c (start_hourglass): Call w32_note_current_window when
4798 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4799 build that caused Emacs to display the hourglass cursor forever.
4801 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4802 which is broken under remote desktop, calculate the number of
4803 colors available for a display based on the display's number of
4804 planes and number of bits per pixel per plane. (bug#10397).
4806 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4808 * nsfont.m (Vfonts_in_cache): New variable.
4809 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4810 are used. Add cached fonts to Vfonts_in_cache.
4811 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4813 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4815 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4817 (FONT_H): Define after FRAME_H.
4818 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4819 Update dependencies.
4821 * w32term.c: Remove leftover declaration of keyboard_codepage.
4823 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4825 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4826 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4827 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4828 (GLOBAL_SOURCES): Add cygw32.c.
4829 ($(BLD)/unexw32.$(O)):
4831 ($(BLD)/w32console.$(O)):
4832 ($(BLD)/w32fns.$(O)):
4833 ($(BLD)/w32heap.$(O)):
4834 ($(BLD)/w32menu.$(O)):
4835 ($(BLD)/w32proc.$(O)): Add w32common.h.
4837 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4839 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4841 2012-10-08 Daniel Colascione <dancol@dancol.org>
4843 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4844 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4845 accidental message numbering hole. Change other messages to
4848 * w32select.h (HAVE_W32SELECT): Remove.
4850 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4851 w32common.h instead of w32heap.h.
4853 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4854 (get_allocation_unit, get_processor_type, get_w32_major_version)
4855 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4856 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4857 (OS_NT, os_subtype, cache_system_info): Move declarations to
4860 * w32heap.c: Include w32common.h.
4861 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4862 (w32_minor_version, w32_build_number, w32_subtype):
4863 Remove duplicate definitions.
4865 * w32fns.c: Include w32common.h; include w32heap.h only in
4868 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4869 Use `report_file_error' instead of `error' in order to better
4870 inform users of what went wrong. Increase NTGUI_UNICODE file
4871 dialog box file name length to 32k, the maximum allowed by the NT
4874 * w32common.h: New file.
4875 (ROUND_UP, ROUND_DOWN, get_page_size)
4876 (get_allocation_unit, get_processor_type, get_w32_major_version)
4877 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4878 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4879 (OS_NT, os_subtype, cache_system_info): Move here.
4881 * unexw32.c, unexcw.c: Include w32common.h.
4883 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4884 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4885 to call syms_of_w32select.
4887 * cygw32.h: Remove obsolete EXFUN declarations.
4889 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4891 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4892 of w32inevt.o from SOME_MACHINE_OBJECTS.
4894 2012-10-08 Daniel Colascione <dancol@dancol.org>
4896 * image.c: Permanent fix for JPEG compilation issue --- limit
4897 jpeglib `boolean' redefinition to Cygwin builds.
4899 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4901 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4903 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4906 2012-10-08 Daniel Colascione <dancol@dancol.org>
4908 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4909 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4910 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4911 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4912 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4913 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4914 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4915 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4916 now a supported configuration.
4918 * Makefile.in: consolidate image variables into LIBIMAGE; add
4919 W32_OBJ and W32_LIBS. Compile new files.
4922 (_DebPrint) declare tracing facility for W32 debugging. We need
4923 to unify tracing later.
4925 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4926 unconditional use of W32 Unicode functions. Cygwin runs only on
4927 100% Unicode operating systems.
4929 * cygw32.c: New file. Define Cygwin-specific facilities.
4930 (Fcygwin_convert_path_to_windows)
4931 (Fcygwin_convert_path_from_windows): New user functions for
4932 accessing Cygwin path-munging routines.
4934 * cygw32.h: New file.
4935 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4936 UTF-16LE strings temporarily inside non-Lisp-visible string
4939 (w32_strerror): Just what it says on the tin.
4941 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4942 also run for Cygwin; both systems have the same problem with using
4943 GUI facilities in a forked child. Also call syms_of_cygw32,
4944 syms_of_w32select in correct places.
4946 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4947 needs fork-then-exec for daemon launching.
4949 * font.h: Include frame.h.
4951 * image.c: Use the image library cache machinery only when we're
4952 compiling for native WINDOWSNT; Cygwin can use shared libraries
4953 like any other Unixlike system.
4955 * keyboard.c: Clarify a comment regarding the input loop.
4957 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4958 functions directly instead of trying to detect at runtime that our
4959 host operating system supports them. We make this change for two
4960 reasons: Cygwin lacks support for the multibyte character
4961 conversion functions used by the legacy menu code, and Cygwin
4962 never needs to rely on non-Unicode APIs.
4964 * unexw32.c (hinst): Declare extern.
4966 * w32.c: Change header order;
4967 (w32_strerror): Move to w32fns.c because we need it for
4968 non-WINDOWSNT builds.
4970 * w32.h: Add #error macro to make sure we don't include w32.h for
4971 Cygwin builds. Remove w32select declarations.
4973 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4974 w32fns.c. w32console.c is WINDOWSNT-only.
4976 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4977 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4979 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4980 (w32_major_version, w32_minor_version, w32_build_number)
4981 (os_subtype, sound_type): Define here
4982 (w32_defined_color): Make color parameter const for consistency
4983 with other _defined_color functions.
4984 (w32_createwindow): Unconditionally call w32_init_class instead of
4985 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4986 through the code is complex and unnecessary because class
4987 registration is practically free.
4988 (w32_name_of_message): New EMACSDEBUG-only function.
4989 (Fset_message_beep): Move here
4990 (Fx_open_connection): Require that the display name for Windows be
4991 "w32" for consistency, emacsclient disambiguation, and maybe, one
4992 day, multi-window-system support.
4993 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4994 Cygwin files for W32 GUI facilities, since these clearly don't
4995 expect Cygwin names.
4996 (_DebPrint): Define.
4997 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4998 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4999 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5000 (w32_last_error): Remove.
5002 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5004 * w32heap.c (syspage_mask): Declare here.
5005 (cache_system_info): Remove.
5007 * w32inevt.c (faked_key): Define globally, not statically.
5008 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5009 (w32_console_toggle_lock_key): Move to w32fns.c.
5011 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5013 * w32proc.c (_DebPrint): Move to w32fns.c.
5014 * w32select.c: Include string.h, stdio.h for Cygwin.
5015 * w32select.h: New File.
5017 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5019 (w32_message_fd): New variable. Under Cygwin, holds the file
5020 descriptor the system used to tell us about pending thread
5023 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5024 that prevented compilation under non-WINDOWSNT systems.
5026 (w32_initialize): Open /dev/windows and assign it to
5027 w32_message_fd. Provide w32 feature.
5029 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5030 (WM_EMACS_INPUT_READY): add.
5031 (prepend_msg, w32_message_fd): Declare globally.
5034 (keyboard_handle): Use only when WINDOWSNT.
5035 (notify_msg_ready): New function. Posts a message to the main
5036 thread's message queue under CYGWIN, which wakes up the main
5037 thread from select(2) by making the /dev/windows file descriptor
5038 ready. Under WINDOWSNT, it sets an event the same way the old
5041 (post, prepend_msg): Actually call notify_msg_ready instead of
5042 setting the input event directly.
5044 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5046 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5047 but it still has blocs in it, don't return it to the system,
5048 instead of aborting. (Bug#12402)
5050 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5052 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5054 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5055 MAC_OS_X_VERSION_10_6.

5060 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5062 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5063 MAC_OS_X_VERSION_10_4.
5065 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5066 MAC_OS_X_VERSION_10_2.
5068 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5070 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5071 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5073 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5074 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5075 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5076 Remove ns_in_resize check.
5077 (ns_clear_frame_area): Remove resize handle code.
5079 * nsfns.m (ns_in_resize): Remove.
5080 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5081 Remove ns_in_resize check.
5083 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5085 Improve sys_siglist detection.
5086 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5087 defined as a macro, as is done in Solaris.
5088 (sys_siglist_entries): New macro.
5089 (save_strsignal): Use it.
5090 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5091 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5093 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5095 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5096 fullscreen/Fullscreen.
5098 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5099 tobar_height is new.
5101 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5102 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5103 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5104 (windowDidResize:): Check for correct window if old style fullscreen.
5105 Capitalize word in comment. Remove incorrect comment.
5106 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5107 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5108 error in drawing background.
5109 (toggleFullScreen:): Remove comment. Rearrange calls.
5110 Set toolbar values to zero, save old height in tobar_height.

5112 (canBecomeMainWindow): New function.
5114 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5116 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5118 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5120 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5122 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5123 that time stamps of directories could also be changed.
5124 Don't request the too broad GENERIC_WRITE, only the more restrictive
5125 FILE_WRITE_ATTRIBUTES access rights.
5127 * fileio.c (Fset_file_times): Special-case ignoring errors for
5128 directories only on MSDOS, not on MS-Windows.
5130 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5132 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5134 2012-10-04 Eli Zaretskii <eliz@gnu.org>

5137 see whether CreateFile failed.
5139 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5141 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5142 to avoid similar races.
5143 * keyboard.c (pending_signals): Now bool, not int.
5145 Port timers to OpenBSD, plus check for timer failures.
5146 OpenBSD problem reported by Han Boetes.
5147 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5149 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5150 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5151 like OpenBSD, which has timer_settime but does not declare it.
5152 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5153 whether to use itimerspec-related primitives. All uses of
5154 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5156 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5158 * profiler.c (handle_profiler_signal): Fix a malloc race
5159 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5161 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5163 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5165 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5167 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5168 consistent with the change in return value of 'safe_strsignal'.
5170 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5172 Prefer plain 'static' to 'static inline' (Bug#12541).
5173 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5174 (bidi_set_sor_type, bidi_push_embedding_level)
5175 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

5180 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5181 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5182 Now 'static', not 'static inline'.
5184 Count overruns when profiling; change units to ns.
5185 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5186 Give extra weight to samples after overruns, to attempt to count
5187 the time more accurately.
5188 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5189 the underlying primitives nominally do ns.
5190 (Fprofiler_cpu_start): Document the change. Mention that
5191 the sampling intervals are only approximate.
5193 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5195 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5197 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5198 case for the special 0 coding-system.
5200 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5201 (Fmake_overlay): Remove redundant tests.
5202 (fix_start_end_in_overlays): Remove redundant recentering.
5204 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5206 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5207 Update dependencies.
5209 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5211 Fix a malloc race condition involving strsignal.
5212 A signal can arrive in the middle of a malloc, and Emacs's signal
5213 handler can invoke strsignal, which can invoke malloc, which is
5214 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5215 Fix it by altering the signal handler so that it does not invoke
5217 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5218 * process.c (status_message): Use const pointer, in case strsignal
5219 is #defined to safe_strsignal.
5220 * sysdep.c (sys_siglist, init_signals): Always define and
5221 initialize a substitute sys_siglist if the system does not define
5222 one, even if HAVE_STRSIGNAL.
5223 (safe_strsignal): Rename from strsignal. Always define,
5224 using sys_siglist. Return a const pointer.
5225 * syssignal.h (safe_strsignal): New decl.
5226 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5228 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5230 * w32proc.c (timer_loop): Fix code that waits for timer
5231 expiration, to avoid high CPU usage.
5233 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5235 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5236 (sweep_weak_table): Remove redundant prototypes.
5238 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5240 * emacs.c: Move the inclusion of TERM_HEADER after including
5241 windows.h on WINDOWSNT. This avoids compilation problems with
5244 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5246 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5247 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5248 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5249 as the previous version used 'void *'.
5251 * ralloc.c (ROUNDUP): Fix last change.
5252 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5255 * w32proc.c <disable_itimers>: New static flag.
5256 (init_timers): Initialize it to zero, after creating the critical
5257 sections used by the timer threads.
5258 (term_timers): Set to 1 before deleting the critical sections.
5259 (getitimer, setitimer): If disable_itimers is non-zero, return an
5260 error indication without doing anything. Reported by Fabrice
5261 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5262 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5264 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5267 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5268 term_ntproc after all the other bookkeeping, to get timers working
5269 as long as possible.
5271 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5273 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5274 Suggested by Juri Linkov in
5275 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5277 Prefer plain 'static' to 'static inline' (Bug#12541).
5278 With static functions, modern compilers inline pretty well by
5279 themselves; advice from programmers often hurts as much as it helps.
5280 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5281 this change shrinks the text size of the Emacs executable by 1.1%
5282 without affecting CPU significantly in my benchmark.
5283 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

5363 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
5365 Revert the FOLLOW-SYMLINKS change for file-attributes.
5366 Doing it right would require several changes to Tramp, and there's
5367 not enough time to get that tested before the freeze today.
5368 * dired.c (directory_files_internal, Ffile_attributes):
5371 * frame.c (x_report_frame_params): Port better to wider ints.
5372 Do not assume that EMACS_UINT is the same width as uprintmax_t,
5373 or that pointers can be printed in 15 decimal digits.
5374 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

5410 * vm-limit.c (lim_data): Now size_t.
5411 (check_memory_limits): Adjust prototypes of real_morecore and
5412 __morecore to receive argument of type ptrdiff_t. Use size_t for

5492 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
5494 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
5496 * w32.h (init_timers, term_timers): Add prototypes.
5498 2012-09-30 Kenichi Handa <handa@gnu.org>
5500 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
5501 to the buffer relocation which may be caused by ccl_driver.

5526 (windowWillResize:toSize:): Check if frame is still maximized.
5527 (initFrameFromEmacs:): Initialize fs_state, fs_before_fs,
5528 next_maximized, maximized_width, maximized_height and nonfs_window.
5529 Call setCollectionBehavior if NEW_STYLE_FS. Initialize bwidth and
5531 (windowWillUseStandardFrame:defaultFrame:): Update frame parameter
5532 fullscreen. Set maximized_width/height. Act on next_maximized.
5534 * nsterm.h (MAC_OS_X_VERSION_10_7, MAC_OS_X_VERSION_10_8): New.
5535 (EmacsView): Add variables for fullscreen.
5536 (handleFS, setFSValue, toggleFullScreen): New in EmacsView.
5537 (EmacsFSWindow): New interface for fullscreen.
5539 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
5541 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
5543 2012-09-30 Chong Yidong <cyd@gnu.org>
5545 * fns.c (Frandom): Doc fix.
5547 2012-09-30 Martin Rudalics <rudalics@gmx.at>
5549 * window.c (Vwindow_combination_limit): New default value.
5550 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
5552 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5554 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
5555 Suggested by Eli Zaretskii in
5556 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
5558 2012-09-30 Eli Zaretskii <eliz@gnu.org>
5560 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
5561 HAVE_TIMER_SETTIME is defined.
5563 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5565 Profiler improvements: more-accurate timers, overflow checks.
5566 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
5567 signal.h, setjmp.h. Include systime.h instead.
5568 (saturated_add): New function.
5569 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
5570 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
5571 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
5573 (enum profiler_cpu_running): New enum.
5574 (profiler_cpu_running): Now of that enum type, not bool.
5575 All uses changed to store the new value.
5576 (handle_profiler_signal): Rename from sigprof_handler_1,
5577 for consistency with other handlers. Do not check whether
5578 cpu_log is a hash-table if garbage collecting, since it
5579 doesn't matter in that case.
5580 (deliver_profiler_signal): Rename from sigprof_handler,
5581 for consistency with other handlers.
5582 (setup_cpu_timer): New function, with much of what used to be in
5583 Fprofiler_cpu_start. Check for out-of-range argument.
5584 Prefer timer_settime if available, and prefer
5585 thread cputime clocks, then process cputime clocks, then
5586 monotonic clocks, to the old realtime clock. Use make_timeval
5587 to round more-correctly when falling back to setitimer.
5588 (Fprofiler_cpu_start): Use it.
5589 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5590 Don't assume that passing NULL as the 2nd argument of setitimer
5591 is the same as passing a pointer to all-zero storage.
5592 Ignore SIGPROF afterwards.
5593 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5594 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5595 non-fatal signal handlers. Ignore SIGPROF on startup.
5596 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5597 in profiler.c, since sysdep.c now uses it.
5599 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
5600 Suggested by Eli Zaretskii in
5601 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

5614 (Fbacktrace_frame): Adjust accordingly.
5616 2012-09-28 Glenn Morris <rgm@gnu.org>
5618 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
5619 (Frun_hook_with_args_until_failure): Doc fixes.
5621 2012-09-28 Eli Zaretskii <eliz@gnu.org>
5623 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
5624 Qautomatic_redisplay and change the symbol name. All users changed.
5626 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>
5628 * profiler.c (sigprof_handler): Fix race condition.

5651 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
5653 * character.h (MAYBE_UNIFY_CHAR): Remove.
5654 * charset.c, charset.h (maybe_unify_char): Now static.
5655 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5656 Since this stuff is now private to charset.c, there's no need for
5657 a public macro and no need to inline by hand.
5659 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
5660 Stefan Monnier <monnier@iro.umontreal.ca>

5688 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
5690 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
5692 Prefer POSIX timers if available.
5693 They avoid a race if the timer is too close to the current time.
5694 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
5695 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
5696 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
5698 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5700 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
5701 CHAR_STRING_ADVANCE.
5702 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
5703 STRING_CHAR_ADVANCE.
5705 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
5707 Move Vlibrary_cache to emacs.c and reset before dumping.

5712 * image.c (reset_image_types): New function.
5714 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

5719 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
5721 * w32.h (Vlibrary_cache): Do not declare.
5723 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5725 * w32proc.c (sys_signal): Handle all signals defined by the
5726 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5727 handlers for signals supported by Windows. Don't override
5728 term_ntproc as the handler for SIGABRT.
5729 (sigaction): Rewrite to call sys_signal instead of duplicating its
5731 (sys_kill): Improve commentary.
5733 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5734 consistency with a signature of a signal handler. All callers
5736 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5737 install term_ntproc as a signal handler for SIGABRT, as that
5738 should be done by the dumped Emacs.
5740 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5742 * w32select.c (term_w32select): Protect against repeated
5743 invocation by setting clipboard_owner to NULL after calling
5746 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5747 and term_ntproc to their modified signatures.
5749 * character.c (char_string, string_char): Remove calls to
5750 MAYBE_UNIFY_CHAR. See the discussion starting at
5751 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
5754 2012-09-25 Chong Yidong <cyd@gnu.org>
5756 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
5758 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5760 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5761 when encountering an unknown bytecode.
5763 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5765 image.c, indent.c: Use bool for booleans.
5766 * dispextern.h (struct image_type): Members valid_p, load, init
5767 now return bool, not int. All uses changed.
5768 * image.c: Omit unnecessary static decls.
5769 (x_create_bitmap_mask, x_build_heuristic_mask):
5770 Return void, not int, since callers don't care about the return value.

5799 Use bool for booleans.
5801 2012-09-24 Chong Yidong <cyd@gnu.org>

5805 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5807 Move pid_t related decls out of lisp.h.
5808 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5809 (interruptible_wait_for_termination):
5810 Move these decls from lisp.h to syswait.h, since they use pid_t.
5811 Needed on FreeBSD; see Herbert J. Skuhra in
5812 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5813 * callproc.c: Include syswait.h.

5859 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5861 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5862 fatal_error_backtrace.
5864 * w32proc.c (sys_kill): Undo last change: don't do anything when
5865 invoked to deliver SIGABRT to our own process. This is now
5866 handled by emacs_raise.
5868 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5870 * w32term.c (w32_read_socket): Remove leftover reference to
5871 interrupt_input_pending.
5873 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5875 Do not use SA_NODEFER.
5876 Problem reported by Dani Moncayo in
5877 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5879 * sysdep.c (emacs_abort): Do not reset signal handler.
5880 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5881 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5882 wanted even on POSIXish hosts, and it doesn't work on Windows.
5884 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5886 * xterm.c (x_term_init): Call fixup_locale before and after calling
5887 gtk_init (Bug#12392).
5889 2012-09-23 Chong Yidong <cyd@gnu.org>
5891 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5892 Vdynamic_library_alist.
5894 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5895 (Fgnutls_available_p): Caller changed.
5897 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5898 (Flibxml_parse_xml_region): Likewise.
5900 * dispextern.h (struct image_type): Remove arg from init function.
5902 * image.c (Finit_image_library, lookup_image_type)
5903 (define_image_type): Remove now-unneeded second arg.
5904 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5905 (init_tiff_functions, init_gif_functions, init_svg_functions):
5906 Arglist and w32_delayed_load calling convention changed.
5907 (gs_type): Remove init_gs_functions; there is no such function.
5908 (valid_image_p, make_image): Fix caller to lookup_image_type.
5910 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5912 Simplify and avoid signal-handling races (Bug#12471).
5914 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5915 Avoid recursive loop if there's a fatal error in the function itself.
5916 * atimer.c (pending_atimers):
5917 * blockinput.h: Don't include "atimer.h"; no longer needed.
5918 (interrupt_input_pending): Remove. All uses removed.
5919 pending_signals now counts both atimers and ordinary interrupts.
5920 This is less racy than having three separate pending-signal flags.
5921 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5923 Rename from their upper-case counterparts BLOCK_INPUT,
5924 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5925 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5926 This makes it easier to access volatile variables more accurately.
5927 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5928 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5929 that's more reliable if the code is buggy and sets
5930 interrupt_input_blocked to a negative value. All uses changed.
5931 * atimer.c (deliver_alarm_signal):
5932 Remove. No need to deliver this to the parent; any thread can
5933 handle this signal now. All uses replaced by underlying handler.
5934 * atimer.c (turn_on_atimers):
5935 * dispnew.c (handle_window_change_signal):
5936 * emacs.c (handle_danger_signal):
5937 * keyboard.c (kbd_buffer_get_event):
5938 Don't reestablish signal handler; not needed with sigaction.
5939 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5941 Rework to avoid unnecessary accesses to volatile variables.
5942 (UNBLOCK_INPUT_TO): Now a function.
5943 (totally_unblock_input, unblock_input): New decls.
5944 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5945 (init_data): Remove. Necessary stuff now done in init_signal.
5946 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5947 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5948 (fatal_error_code): Remove; no longer needed.
5949 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5950 it doesn't always backtrace. All uses changed. No need to reset
5951 signal to default, since sigaction and/or die does that for us now.
5952 Use emacs_raise (FOO), not kill (getpid (), FOO).
5953 (main): Check more-accurately whether we're dumping.
5954 Move fatal-error setup to sysdep.c
5955 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5956 * gtkutil.c (xg_get_file_name, xg_get_font):
5957 Remove no-longer-needed signal-mask manipulation.
5958 * keyboard.c, process.c (POLL_FOR_INPUT):
5959 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5960 * keyboard.c (read_avail_input): Remove.
5961 All uses replaced by gobble_input.
5962 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5963 (kbd_buffer_store_event_hold, gobble_input):
5964 (record_asynch_buffer_change) [USABLE_SIGIO]:
5965 (store_user_signal_events):
5966 No need to mess with signal mask.
5967 (gobble_input): If blocking input and there are terminals, simply
5968 set pending_signals to 1 and return. All hooks changed to not
5969 worry about whether input is blocked.
5970 (process_pending_signals): Clear pending_signals before processing
5971 them, in case a signal comes in while we're processing.
5972 By convention callers now test pending_signals before calling us.
5973 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5974 New functions, to support changes to blockinput.h.
5975 (handle_input_available_signal): Now extern.
5976 (reinvoke_input_signal): Remove. All uses replaced by
5978 (quit_count): Now volatile, since a signal handler uses it.
5979 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5980 All callers changed. Block SIGINT only if not already blocked.
5981 Clear sigmask reliably, even if Fsignal returns, which it can.
5982 Omit unnecessary accesses to volatile var.
5983 (quit_throw_to_read_char): No need to restore sigmask.
5984 * keyboard.c (gobble_input, handle_user_signal):
5985 * process.c (wait_reading_process_output):
5986 Call signal-handling code rather than killing ourselves.
5987 * lisp.h: Include <float.h>, for...
5988 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5989 (pending_signals): Now volatile.
5990 (syms_of_data): Now const if IEEE floating point.
5991 (handle_input_available_signal) [USABLE_SIGIO]:
5992 (terminate_due_to_signal, record_child_status_change): New decls.
5993 * process.c (create_process): Avoid disaster if memory is exhausted
5994 while we're processing a vfork, by tightening the critical section
5996 (send_process_frame, process_sent_to, handle_pipe_signal)
5997 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5999 (send_process): No need for setjmp/longjmp any more, since the
6000 SIGPIPE stuff is now gone. Instead, report an error if errno
6002 (record_child_status_change): Now extern. PID and W are now args.
6003 Return void, not bool. All callers changed.
6004 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6005 Remove. All uses removed. This bug should be fixed now in a
6007 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6008 and record the child status change directly. This avoids the
6009 need to futz with the signal mask.
6010 (process_fatal_action): Move here from emacs.c.
6011 (emacs_sigaction_flags): New function, containing
6012 much of what used to be in emacs_sigaction_init.
6013 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6014 caught by emacs, to make races less likely.
6015 (deliver_process_signal): Rename from handle_on_main_thread.
6017 (BACKTRACE_LIMIT_MAX): Now at top level.
6018 (thread_backtrace_buffer, threadback_backtrace_pointers):
6020 (deliver_thread_signal, deliver_fatal_thread_signal):
6021 New functions, for more-accurate delivery of thread-specific signals.
6022 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6023 (deliver_arith_signal): Handle in this thread, not
6024 in the main thread, since it's triggered by this thread.
6025 (maybe_fatal_sig): New function.
6026 (init_signals): New arg DUMPING so that we can be more accurate
6027 about whether we're dumping. Caller changed.
6028 Treat thread-specific signals differently from process-general signals.
6029 Block all signals while handling fatal error; that's safer.
6030 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6032 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6033 Ignore SIGPIPE unless batch.
6034 (emacs_backtrace): Output backtrace for the appropriate thread,
6035 which is not necessarily the main thread.
6036 * syssignal.h: Include <stdbool.h>.
6037 (emacs_raise): New macro.
6038 * xterm.c (x_connection_signal): Remove; no longer needed
6039 now that we use sigaction.
6040 (x_connection_closed): No need to mess with sigmask now.
6041 (x_initialize): No need to reset SIGPIPE handler here, since
6042 init_signals does this for us now.
6044 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6046 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6047 background rect may be larger (Bug#12245).
6049 2012-09-23 Chong Yidong <cyd@gnu.org>
6051 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6053 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6055 * .gdbinit: Just stop at fatal_error_backtrace.
6056 See Stefan Monnier's request in
6057 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6058 Remove no-longer-used query of system type.
6060 2012-09-22 Chong Yidong <cyd@gnu.org>
6062 * search.c (Freplace_match): Doc fix (Bug#12325).
6064 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6066 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6067 (Fline_end_position): Doc fix.
6069 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6071 2012-09-22 Chong Yidong <cyd@gnu.org>
6073 * dispextern.h (struct image_type): Add new slot, storing a type
6074 initialization function.
6076 * image.c (define_image_type): Call the image initializer function
6077 if it is defined. Arguments and return value changed.
6078 (valid_image_p, make_image): Callers changed.
6079 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6080 (gif_type, imagemagick_type, svg_type, gs_type):
6081 Add initialization functions.
6082 (Finit_image_library): Call lookup_image_type.
6083 (CHECK_LIB_AVAILABLE): Macro deleted.
6084 (lookup_image_type): Call define_image_type here, rather than via
6085 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6086 (syms_of_image): Move define_image_type calls for xbm_type and
6087 pbm_type to lookup_image_type.
6089 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6091 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6092 'idle_timers' from here ...
6093 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6094 lists, to avoid infloops when the timer does something stupid,
6095 like reinvoke itself with the same or smaller time-out.
6098 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6100 * window.c (Fsplit_window_internal): Handle only Qt value of
6101 Vwindow_combination_limit separately.
6102 (Qtemp_buffer_resize): New symbol.
6103 (Vwindow_combination_limit): New default value.
6106 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6108 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6109 the new overlay string. (Bug#10159)
6111 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6113 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6114 or that fprintf is async-signal-safe. POSIX doesn't require
6117 2012-09-22 Chong Yidong <cyd@gnu.org>
6119 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6122 2012-09-22 Kenichi Handa <handa@gnu.org>
6124 * composite.c (composition_reseat_it): Handle the case that a
6125 grapheme cluster is not covered by a single font (Bug#12352).
6127 2012-09-21 Chong Yidong <cyd@gnu.org>
6129 * image.c (define_image_type): Avoid adding duplicate types to
6130 image_types (Bug#12463). Suggested by Jörg Walter.
6132 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6134 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6135 (print_load_command_name): Add case LC_DATA_IN_CODE.
6136 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6138 2012-09-21 Glenn Morris <rgm@gnu.org>
6140 * eval.c (Frun_hook_with_args_until_success)
6141 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6143 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6145 * fileio.c (Ffile_selinux_context): Only call freecon when
6146 lgetfilecon succeeded.
6147 (Fset_file_selinux_context): Likewise. (Bug#12444)
6149 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6151 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6152 reordering, locate the cursor by calling set_cursor_from_row; if
6153 that fails, clear the desired glyph matrix before returning a
6154 failure indication to the caller. Fixes leaving garbled display
6155 when fast scrolling with a down-key. (Bug#12403)
6156 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6157 scrolling through multibyte text.
6159 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6161 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6162 calling mark_vectorlike since that's the one that marks the window.
6163 (mark_discard_killed_buffers): Mark the final cdr.
6164 * window.h (struct window): Move prev/next_buffers to the
6165 non-standard fields.
6166 * window.c (make_window): Initialize prev/next_buffers manually.
6168 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6170 Omit unused arg EXPECTED from socket hooks.
6171 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6172 * nsterm.m (ns_term_init):
6173 * termhooks.h (struct terminal.read_socket_hook):
6174 * w32inevt.c (w32_console_read_socket):
6175 * w32term.c (w32_read_socket):
6176 * xterm.c (XTread_socket):
6177 Omit unused arg EXPECTED. All callers changed.
6178 (store_user_signal_events): Return void, not int, since callers no
6179 longer care about the return value. All uses changed.
6181 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6183 * w32gui.h (XParseGeometry): Do not declare.
6185 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6187 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6188 Ignore 'expected'. See Eli Zaretskii in
6189 <http://bugs.gnu.org/12471#8> (last line).
6191 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6192 (XParseGeometry): Now static. Substitute extremal values for
6193 values that are out of range.
6195 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6197 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6199 * nsfns.m (XParseGeometry): Remove.
6200 (Fx_create_frame): Call x_set_offset to correctly interpret
6201 top_pos in geometry.
6203 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6204 (Fx_parse_geometry): If there is a space in string, call
6205 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6207 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6209 * search.c (scan_buffer): Use character positions in calls to
6210 region_cache_forward and region_cache_backward, not byte
6211 positions. (Bug#12196)
6213 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6214 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6216 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6217 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6218 emacs_blocked_malloc, now deleted.
6220 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6222 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6223 The workaround was for improving performance on Solaris 2.4, but
6224 is getting in the way now. Emacs will still work if someone is
6225 still running Solaris 2.4 in a museum somewhere; Sun dropped
6226 support for Solaris 2.4 in 2003.
6227 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6228 * process.c (create_process) [HAVE_WORKING_VFORK]:
6229 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6230 since Emacs no longer uses vfork on that platform.
6232 2012-09-17 Glenn Morris <rgm@gnu.org>
6234 * emacs.c: Use COPYRIGHT.
6236 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6238 Remove configure's --without-sync-input option (Bug#12450).
6239 When auditing signal-handling in preparation for cleaning it up,
6240 I found that SYNC_INPUT has race conditions and would be a real
6241 pain to fix. Since it's an undocumented and deprecated
6242 configure-time option, now seems like a good time to remove it.
6243 Also see <http://bugs.gnu.org/11080#16>.
6244 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6245 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6246 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6247 (malloc_hysteresis):
6248 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6249 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6250 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6251 (dont_register_blocks, bytes_used_when_reconsidered)
6252 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6253 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6254 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6255 Remove. All uses removed.
6256 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6257 implementation, one that depends on whether the new macro
6258 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6260 * atimer.c (run_timers, handle_alarm_signal):
6261 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6262 (handle_async_input, process_pending_signals)
6263 (handle_input_available_signal, init_keyboard):
6264 * nsterm.m (ns_read_socket):
6265 * process.c (wait_reading_process_output):
6266 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6267 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6269 * xterm.c (XTread_socket):
6271 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6272 * eval.c (handling_signal): Remove. All uses removed.
6273 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6274 All uses replaced with the SYNC_INPUT version.
6275 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6277 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6280 * font.c (Ffont_shape_gstring): Remove unused local.
6282 2012-09-16 Glenn Morris <rgm@gnu.org>
6284 * Makefile.in (clean): No longer run nextstep's clean.
6286 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6288 (ns-app): Move here from ns.mk, and simplify.
6289 (clean): Simplify nextstep entry.
6290 * ns.mk: Remove file.
6292 2012-09-17 Kenichi Handa <handa@gnu.org>
6294 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6295 not covert the last few charactes.
6297 2012-09-16 Kenichi Handa <handa@gnu.org>
6299 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6300 here, but just check the validity of glyphs in the glyph-string.
6302 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6304 * window.c (Fwindow_parameter, Fset_window_parameter):
6305 Accept any window as argument (Bug#12452).
6307 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6309 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6310 to ns_term_init to avoid memory leak.
6312 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6313 explicit retain/release.
6314 (ns_term_init): Only allow one display. Initialize outerpool and
6317 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6319 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6320 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6321 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6322 the Microsoft problem in a different way, by altering ../nt/config.nt.
6324 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6339 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6340 by lisp.h. This completes removal of setjmp.h inclusion
6341 erroneously announced in the previous commit. (Bug#12446)
6343 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6346 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6347 not defined as a macro. The latter happens on MS-Windows.
6350 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6352 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6353 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6354 Some instances of '#include <setjmp.h>' removed, if the
6355 only reason for the instance was because "lisp.h" was included.
6356 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6357 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6358 and _longjmp with the new symbols. Emacs already uses _setjmp if
6359 available, so this change affects only POSIXish hosts that have
6360 sigsetjmp but not _setjmp, such as some versions of Solaris and
6361 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6362 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6363 (png_load_body) [HAVE_PNG]:
6364 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6365 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6366 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6367 since PNG requires jmp_buf. This is the only exception to the
6368 general rule that we now use sys_setjmp and sys_longjmp.
6369 This exception is OK since this code does not change the signal
6370 mask or longjmp out of a signal handler.
6372 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6374 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6375 Include "syssignal.h", for 'main_thread'.
6377 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6379 Avoid out-of-range marker position (Bug#12426).
6380 * insdel.c (replace_range, replace_range_2):
6381 Adjust markers before overlays, as suggested by comments.
6382 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6383 Remove redundant check before calling offset_intervals.
6385 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6387 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6388 current buffer (Bug#12387).
6390 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6392 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6394 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6396 Use a more backwards-compatible timer format (Bug#12430).
6397 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6398 vector element, not from the 4th, since PSECS is now at the end.
6399 (Fcurrent_idle_time): Doc fix.
6401 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6403 Function to mark objects and remove killed buffers at once.
6404 * alloc.c (discard_killed_buffers): Rename to ...
6405 (mark_discard_killed buffers) ... new name. Add marking
6406 of remaining objects. Fix comment. Adjust users.
6407 (mark_object): Do not touch frame buffer lists here.
6408 * frame.c (delete_frame): Reset frame buffer lists here.
6410 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6412 Better workaround for GNOME bug when --enable-gcc-warnings.
6413 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6414 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6415 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6417 Simplify SIGIO usage (Bug#12408).
6418 The code that dealt with SIGIO was crufty and confusing, e.g., it
6419 played tricks like "#undef SIGIO" but these tricks were not used
6420 consistently. Simplify mostly by not #undeffing standard symbols,
6421 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6422 or not as we please) rather than "defined SIGIO" (standard symbol
6423 that we probably shouldn't #undef).
6424 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6425 Modules that need it can include it.
6426 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6427 * dispextern.h (ignore_sigio): New decl.
6428 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6429 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6430 * emacs.c (shut_down_emacs):
6431 * keyboard.c (kbd_buffer_store_event_hold):
6432 Use ignore_sigio rather than invoking 'signal' directly.
6433 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6435 (FIONREAD, SIGIO): Do not #undef.
6436 (tty_read_avail_input): Use #error rather than a syntax error.
6437 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6438 for I_PIPE, used by SETUP_SLAVE_PTY.
6439 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6440 * sysdep.c (croak): Remove; no longer needed. This bit of
6441 temporary code, with Fred N. Fish's comment that it's temporary,
6442 has been in Emacs since at least 1992!
6443 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6444 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6445 * syssignal.h (croak): Remove decl.
6446 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6447 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6448 now that we're termios-only.
6449 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6450 * term.c (dissociate_if_controlling_tty): Use #error rather than
6453 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6454 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6455 to work around GNOME bug 683906.
6456 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6457 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6458 This works around GCC bug 54561.
6460 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6462 More fixes for 'volatile' and setjmp/longjmp.
6463 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6464 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6465 (png_load_body) [HAVE_PNG]:
6466 (jpeg_load_body) [HAVE_JPEG]:
6467 New function, with most of the old parent function's body.
6468 (png_load) [HAVE_PNG]:
6469 (jpeg_load) [HAVE_JPEG]:
6470 Invoke the new function, to avoid longjmp munging our locals.
6471 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6472 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6473 longjmp is passed 2, as the C standard doesn't guarantee this.
6474 Instead, store the failure code into mgr->failure_code.
6476 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6478 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6479 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6480 (syms_of_keyboard): Remove support for unread-command-char.
6482 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6484 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6485 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6486 violation. (Bug#12426)
6488 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6490 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6492 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6494 * eval.c: Add `inhibit-debugger'.
6495 (Qinhibit_debugger): New symbol.
6496 (call_debugger): Bind it instead of Qdebug_on_error.
6497 (maybe_call_debugger): Test Vinhibit_debugger.
6498 (syms_of_eval): Define inhibit-debugger.
6499 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6500 (syms_of_xdisp): Remove inhibit-debug-on-message.
6502 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6504 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6505 If a nonvolatile local variable is written before a _longjmp to
6506 the frame containing the variable, and is read after the _longjmp,
6507 the value read is indeterminate. Some local variables of type
6508 'struct handler' and 'struct catchtag' are used in this way, so
6509 mark each of their slots as volatile if the slot can be set before
6510 _longjmp and read afterwards.
6511 * lisp.h (struct handler): var and chosen_clause are now volatile.
6512 (struct catchtag): val, next, and pdlcount are now volatile.
6514 * bidi.c (bidi_push_it, bidi_pop_it):
6515 * fns.c (copy_hash_table):
6516 * image.c (define_image_type):
6517 * keyboard.c (kbd_buffer_store_event_hold):
6518 * process.c (Fprocess_send_eof):
6519 * xfaces.c (x_create_gc) [HAVE_NS]:
6520 * xgselect.c (xg_select):
6521 Prefer assignment to memcpy when either will do.
6523 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6524 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6525 time an item is removed. No need to mark this function 'inline';
6526 the compiler knows better than we do.
6528 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6530 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6531 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6532 to change_frame_size (Bug#12388).
6533 (windowDidResize:): Pass YES to updateFrameSize.
6535 * nsterm.h: Add delay parameter to updateFrameSize.
6537 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6539 Discard killed buffers from deleted window and frame objects.
6540 This reduces an amount of references to killed buffers and
6541 helps GC to reclaim them faster.
6542 * alloc.c (discard_killed_buffers): New function.
6543 (mark_object): Use it for deleted windows and frames.
6544 (mark_object): If symbol's value is set up for a killed buffer
6545 or deleted frame, restore its global binding.
6546 * data.c (swap_in_global_binding): Add GC notice.
6547 (swap_in_symval_forwarding): Use convenient set_blv_where.
6548 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6549 * window.h: ... to here.
6551 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6553 Convenient macro to check whether the buffer is live.
6554 * buffer.h (BUFFER_LIVE_P): New macro.
6555 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6556 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6558 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6560 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6561 composition cases (Bug#12364).
6563 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6564 overhang of succeeding glyphs overlapping box cursor.
6566 * w32term.c (x_draw_glyph_string): Likewise.
6568 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6570 Simplify, document, and port floating-point (Bug#12381).
6571 The porting part of this patch fixes bugs on non-IEEE platforms
6572 with frexp, ldexp, logb.
6573 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6575 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6576 support, by removing commented-out code and briefly listing the
6577 C89 functions excluded. The commented-out stuff was confusing
6578 maintenance, e.g., we thought we needed cbrt but it was commented out.
6579 (logb): Remove decl; no longer needed.
6580 (isfinite): New macro, if not already supplied.
6581 (isnan): Don't replace any existing macro.
6582 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6583 are present on all C89 platforms.
6584 (Ffrexp): Do not special-case zero, as frexp does the right thing
6586 (Flogb): Do not use logb, as it doesn't have the desired meaning
6587 on hosts that use non-base-2 floating point. Instead, stick with
6588 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6589 frexp, to avoid getting an unspecified result.
6591 * xdisp.c (Qinhibit_debug_on_message): Now static.
6593 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6595 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6596 NSBezierPath (Bug#12131).
6598 2012-09-10 Chong Yidong <cyd@gnu.org>
6600 * fns.c (Fdelq, Fdelete): Doc fix.
6602 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6604 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6605 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6607 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6609 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6610 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6613 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6615 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6616 left fringe if the window has a left margin. This avoids leaving
6617 traces of the cursor because its leftmost pixel is not drawn over.
6619 * dispnew.c (update_window_line): When the left margin area of a
6620 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6621 that screen line. (Bug#12277)
6623 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6625 Assume C89 or later for math functions (Bug#12381).
6626 This simplifies the code, and makes it a bit smaller and faster,
6627 and (most important) makes it easier to clean up signal handling
6628 since we can stop worring about floating-point exceptions in
6629 library code. That was a problem before C89, but the problem
6630 went away many years ago on all practical Emacs targets.
6631 * data.c, image.c, lread.c, print.c:
6632 Don't include <math.h>; no longer needed.
6633 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6634 might be autoconfigured, as that never happens.
6636 * doprnt.c (DBL_MAX_10_EXP):
6637 * print.c (DBL_DIG):
6638 Remove. C89 or later always defines these.
6639 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6640 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6641 (arith_error, domain_error, domain_error2):
6642 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6643 no longer needed -- we simply return what C returns. All uses removed.
6644 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6646 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6647 Remove. All uses expanded, as these macros are no longer used
6648 more than once and are now more trouble than they're worth.
6649 (Ftan): Use tan, not sin / cos.
6650 (Flogb): Assume C89 frexp.
6651 (fmod_float): Assume C89 fmod.
6652 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6653 (init_floatfns): Remove. All uses removed.
6655 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6657 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6658 compositeToPoint for OSX < 10.6 (Bug#12390).
6660 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6662 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6663 This produces more-accurate results.
6665 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6667 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6668 changes (Bug#12088).
6670 2012-09-08 Chong Yidong <cyd@gnu.org>
6672 * syntax.c (Fstring_to_syntax): Doc fix.
6674 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6676 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6677 in the internal border.
6678 (x_set_window_size): Remove static variables and their usage.
6679 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6680 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6681 Remove fringe/internal border adjustment (Bug#11052).
6682 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6683 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6684 (ns_fix_rect_ibw): Remove.
6685 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6686 (ns_dumpglyphs_box_or_relief): Ditto.
6687 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6689 (ns_dumpglyphs_image): Ditto.
6690 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6692 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6693 their usage. Add fringe_extended_p and its use as in other terms.
6694 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6695 scroll bar was removed.
6696 (updateFrameSize): New function.
6697 (windowDidResize): Move code to updateFrameSize and call it.
6699 * nsterm.h (EmacsView): Add updateFrameSize.
6701 2012-09-07 Chong Yidong <cyd@gnu.org>
6703 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6705 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6707 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6709 More signal-handler cleanup (Bug#12327).
6710 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6711 Problem introduced when merging patches. Noted by Eli Zaretskii in
6712 <http://bugs.gnu.org/12327#67>.
6713 * floatfns.c: Comment fix.
6714 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6715 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6716 and anyway the declaration is harmless even if SIGDANGER is not defined.
6717 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6718 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6719 source files not surprisingly expected syssignal.h to define, or
6720 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6721 Include <sys/ioctl.h>, for FIONREAD.
6722 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6723 This eliminates a problem whereby other files mysteriously had
6724 to include "syssignal.h" before including "systty.h" if they
6725 wanted to use "#ifdef SIGIO".
6727 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6729 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6731 * w32.c (sigemptyset): Empty the set.
6732 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6734 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6736 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6738 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6739 (mark_object): Likewise for frame objects.
6741 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6743 * syssignal.h (handle_on_main_thread): Always declare,
6744 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6745 This ports to platforms without HAVE_PTHREAD.
6747 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6749 Signal-handler cleanup (Bug#12327).
6750 Emacs's signal handlers were written in the old 4.2BSD style with
6751 sigblock and sigmask and so forth, and this led to some
6752 inefficiencies and confusion. Rewrite these to use
6753 pthread_sigmask etc. without copying signal sets around. Also,
6754 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6755 'signal', and instead use functions that do not attempt to take
6756 over the system name space. This patch causes Emacs's text
6757 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6758 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6759 Do not include <signal.h> or "syssignal.h", as these
6760 modules do not use signals.
6761 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6762 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6763 Do not include <signal.h>, as "syssignal.h" does that for us now.
6764 * atimer.c (sigmask_atimers): New function.
6765 (block_atimers, unblock_atimers): New functions,
6766 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6768 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6769 no longer needed here.
6770 * emacs.c (main): Inspect existing signal handler with sigaction,
6771 so that there's no need to block and unblock SIGHUP.
6772 * sysdep.c (struct save_signal): New member 'action', replacing
6773 old member 'handler'.
6774 (save_signal_handlers, restore_signal_handlers):
6775 Use sigaction instead of 'signal' to save and restore.
6776 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6777 New function. All users of 'signal' modified to use set_sighandler
6778 if they're writeonly, and to use sys_signal if they're read+write.
6779 (emacs_sigaction_init, forwarded_signal): New functions.
6780 (sys_signal): Remove. All uses replaced by calls to sigaction
6781 and emacs_sigaction_init, or by direct calls to 'signal'.
6782 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6783 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6784 all uses replaced by pthread_sigmask etc. calls.
6785 * syssignal.h: Include <signal.h>.
6786 (emacs_sigaction_init, forwarded_signal): New decls.
6787 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6788 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6789 (sigmask, sys_sigmask): Remove; no longer needed.
6790 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6791 (sigblock, sigunblock, sigfree):
6792 (sigsetmask) [!defined sigsetmask]:
6793 Remove. All uses replaced by pthread_sigmask.
6794 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6795 no longer need to be replaced, and its typical old uses
6796 are now done via emacs_sigaction_init and sigaction.
6797 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6798 (sys_sigdel): Remove; unused.
6799 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6801 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6803 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6804 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6806 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6808 Explicitly mark buffer_defaults and buffer_local_symbols.
6809 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6810 mark_local_symbols here.
6811 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6812 since special buffers aren't marked here any more.
6813 (allocate_buffer): Chain new buffer with all_buffers here...
6814 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6816 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6817 (syms_of_buffer): Remove staticpro of the above.
6818 (init_buffer_once): Set names for buffer_defaults and
6819 buffer_local_symbols.
6821 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6823 Use bool for booleans in font-related modules.
6824 * font.c (font_intern_prop, font_style_to_value)
6825 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6826 (generate_otf_features, font_check_otf_features, font_check_otf)
6827 (font_match_p, font_list_entities, font_at):
6828 * fontset.c (fontset_id_valid_p, reorder_font_vector
6829 (fontset_find_font, Fset_fontset_font)
6830 (face_suitable_for_char_p) [0]:
6831 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6832 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6833 (m17n_flt_initialized, ftfont_shape_by_flt):
6834 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6835 * nsfont.m (nsfont_draw):
6836 * w32font.c (w32font_draw):
6837 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6838 Use bool for booleans.
6839 * font.h: Adjust to above API changes.
6840 (struct font, struct font_driver, struct font_driver_list):
6841 Use bool for booleans.
6842 (struct font): Remove useless member encoding_type.
6844 * fontset.c, xftfont.c: Omit unnecessary static decls.
6846 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6848 * alloc.c (mark_object): Revert window marking code
6849 since it's unsafe for the Fset_window_configuration.
6851 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6853 Fix race conditions with signal handlers and errno (Bug#12327).
6854 Be more systematic about preserving errno whenever a signal
6855 handler returns, even if it's not in the main thread. Do this by
6856 renaming signal handlers to distinguish between signal delivery
6857 and signal handling. All uses changed.
6858 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6859 * data.c (deliver_arith_signal): Rename from arith_error.
6860 * dispnew.c (deliver_window_change_signal): Rename from
6861 window_change_signal.
6862 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6863 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6864 * keyboard.c (deliver_input_available_signal): Rename from
6865 input_available_signal.
6866 (deliver_user_signal): Rename from handle_user_signal.
6867 (deliver_interrupt_signal): Rename from interrupt_signal.
6868 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6869 (deliver_child_signal): Rename from sigchld_handler.
6870 * atimer.c (handle_alarm_signal):
6871 * data.c (handle_arith_signal):
6872 * dispnew.c (handle_window_change_signal):
6873 * emacs.c (handle_fatal_signal, handle_danger_signal):
6874 * keyboard.c (handle_input_available_signal):
6875 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6876 * process.c (handle_pipe_signal, handle_child_signal):
6877 New functions, with the actual signal-handling code taken from the
6878 original respective signal handlers, sans the sporadic attempts to
6879 preserve errno, since that's now done by handle_on_main_thread.
6880 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6881 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6882 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6884 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6885 Move initialization of main_thread to sysdep.c's init_signals.
6886 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6887 our usage, and simplifies the mainline code.
6888 (record_child_status_change): New static function, as a helper
6889 for handle_child_signal, and with most of the old child handler's
6891 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6892 (handle_child_signal): Use the above.
6893 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6894 Moved here from emacs.c.
6895 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6896 code moved here from emacs.c's main function.
6897 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6898 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6899 This lets callers save and restore errno properly.
6901 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6903 Remove redundant or unused things here and there.
6904 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6905 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6906 * editfns.c (Fcompare_buffer_substrings): Likewise.
6907 * frame.h (struct terminal, struct font_driver_list):
6908 Remove redundant declarations.
6909 * window.h (Qleft, Qright): Likewise.
6911 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6913 Do not mark objects from deleted buffers, windows and frames.
6914 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6915 (mark_object): Likewise for windows and frames.
6917 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6919 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6920 buffer_defaults and buffer_local_symbols as valid objects.
6921 Return special value to denote them.
6923 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6925 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6926 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6927 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6928 (file_name_absolute_p, Fsubstitute_in_file_name):
6929 (check_executable, check_writable, Ffile_accessible_directory_p)
6930 (Fset_file_selinux_context, Fdefault_file_modes)
6931 (Finsert_file_contents, choose_write_coding_system)
6932 (Fwrite_region, build_annotations, a_write, e_write)
6934 * filelock.c (boot_time_initialized, get_boot_time)
6935 (get_boot_time_1, lock_file_1, within_one_second):
6936 * floatfns.c (in_float):
6937 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6938 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6939 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6940 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6941 * window.c (compare_window_configurations):
6942 Use bool for booleans.
6943 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6944 (Fdefault_file_modes): Now mode_t, not int, for modes.
6945 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6946 (internal_delete_file): Now returns void, not a (boolean) int,
6947 since nobody was looking at the return value.
6948 * lisp.h, window.h: Adjust to above API changes.
6950 * xdisp.c (set_message): Simplify and reindent last change.
6952 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6954 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6956 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6958 * eval.c (call_debugger): Make the function non-static so that we
6959 can call it from set_message.
6961 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6962 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6964 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6966 Give more-useful info on a fatal error (Bug#12328).
6967 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6968 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6969 of doing the work ourselves.
6970 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6971 do most of the work.
6972 (fatal_error_backtrace): New function, taken from the guts
6973 of the old fatal_error_signal, but with a new option to output
6975 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6976 info about the signal than just its number.
6977 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6978 * sysdep.c: Include <execinfo.h>
6979 (emacs_backtrace): New function, taken partly from the previous
6980 code of the 'die' function.
6981 (emacs_abort): Call fatal_error_backtrace rather than abort.
6983 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6985 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6986 eager (load-time) macro-expansion.
6987 * lisp.mk (lisp): Add macroexp.
6989 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6991 Simplify redefinition of 'abort' (Bug#12316).
6992 Do not try to redefine the 'abort' function. Instead, redo
6993 the code so that it calls 'emacs_abort' rather than 'abort'.
6994 This removes the need for the NO_ABORT configure-time macro
6995 and makes it easier to change the abort code to do a backtrace.
6996 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6997 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6998 Remove; sysdep.c's emacs_abort now takes its place.
6999 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7000 'abort' changed to use 'emacs_abort'.
7001 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7002 (abort) [!defined abort]: Rename to ...
7003 (emacs_abort): ... new name.
7004 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7005 the place of the old 'abort' in emacs.c.
7006 * w32.c, w32fns.c (abort): Do not #undef.
7007 * w32.c (emacs_abort): Rename from w32_abort.
7009 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7011 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7012 offsets[j].dv, since the y axis of the screen coordinates points
7013 down, while the y axis of the font definition coordinates points
7014 up. This fixes display of Arabic diacritics such as KASRA and
7015 KASRATAN. (Bug#11860)
7017 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7019 Be more systematic about _setjmp vs setjmp.
7020 * alloc.c (test_setjmp, mark_stack):
7021 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7022 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7023 (png_load, my_error_exit, jpeg_load):
7024 * process.c (send_process_trap, send_process):
7025 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7026 The underscored versions are up to 30x faster on some hosts.
7027 Formerly, the code used setjmp+longjmp sometimes and
7028 _setjmp+_longjmp at other times, with no particular reason to
7029 prefer setjmp+longjmp.
7031 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7033 Fix minor problem found by static checking.
7034 * buffer.c (Fdelete_all_overlays): Return nil.
7036 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7038 * buffer.c (Fdelete_all_overlays): New function.
7040 2012-09-03 Chong Yidong <cyd@gnu.org>
7042 * gtkutil.c: Add extern decl for Qxft.
7044 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
7046 * emacs.c, eval.c: Use bool for boolean.
7047 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
7048 (malloc_using_checking) [DOUG_LEA_MALLOC]:
7049 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
7050 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
7051 (main, decode_env_path, Fdaemon_initialized):

7053 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
7054 (maybe_call_debugger, Fbacktrace):
7055 * process.c (read_process_output, exec_sentinel):
7056 Use bool for booleans.
7057 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
7058 All callers changed.
7059 * eval.c (interactive_p): Omit always-true boolean argument
7060 EXCLUDE_SUBRS_P. All callers changed.
7061 * dispextern.h, lisp.h: Reflect above API changes.
7062 * firstfile.c (dummy): Use the address of 'main', whose signature
7063 won't change, instead of the address of 'initialize', whose
7064 signature just changed from int to bool.
7065 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7066 * msdos.c (fatal_error_in_progress): ... from here.
7067 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7069 (redisplay_internal, unwind_redisplay): Simply clear
7070 REDISPLAYING_P when unwinding, instead of saving its previous,
7071 always-false value and then restoring it.
7073 Clean up some extern decls.
7074 Mostly, this hoists extern decls out of .c files and into .h files.
7075 That way, we're more likely to catch errors if the interfaces change.
7076 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7077 declare xg_mark_data.
7078 * dispextern.h (x_frame_parm_handlers):
7080 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
7081 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
7082 (Qultra_bold, Qoblique, Qitalic):
7083 Move extern decl here from .c file.
7084 * alloc.c (xg_mark_data) [USE_GTK]:
7086 * eval.c (Qlexical_binding):
7087 * fns.c (time) [!HAVE_UNISTD_H]:

7093 * process.c (QCfamily, QCfilter):
7094 * widget.c (free_frame_faces):
7095 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
7096 * xfont.c (x_clear_errors):
7097 * xterm.c (x_frame_parm_handlers):
7098 Remove now-redundant extern decls.
7099 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7100 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7102 * xfaces.c: Remove unnecessary static decls.
7103 * xterm.c (updating_frame): Remove decl of nonexistent object.
7105 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7106 when building globals.h, as the objects that are not built on
7107 this host are not needed to compile C files on this host.
7109 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
7111 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

7119 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
7120 (Fsubstitute_command_keys):

7122 (save_excursion_save, save_excursion_restore)
7123 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
7124 (format_time_string, general_insert_function)
7125 (make_buffer_string, make_buffer_string_both)
7126 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
7127 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)
7128 (copy_text, insert_1, insert_1_both, insert_from_string)
7129 (insert_from_string_before_markers, insert_from_string_1)

7136 (adjust_for_invis_intang, set_point_both)
7137 (get_property_and_range, compare_string_intervals)
7138 (set_intervals_multibyte_1, set_intervals_multibyte):
7139 * keyboard.c (decode_timer):
7140 Use bool for boolean.

7146 * keymap.c (push_key_description): Print M-TAB as C-M-i
7149 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
7151 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
7152 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

7157 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
7159 2012-09-01 Eli Zaretskii <eliz@gnu.org>
7161 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7162 more than one grapheme cluster passed to the shaper: compute the
7163 offset adjustment values separately for each cluster. (Bug#11860)
7165 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7166 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7167 about implicit conversions from integer to pointer.
7169 2012-09-01 Daniel Colascione <dancol@dancol.org>
7171 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7172 system used too early.
7174 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
7176 Better seed support for (random).
7177 * emacs.c (main): Call init_random.
7178 * fns.c (Frandom): Set the seed from a string argument, if given.
7179 Remove long-obsolete Gentzel cruft.

7191 all of which have been moved to common code.
7193 * xfaces.c: Include TERM_HEADER instead of listing all possible
7194 window-system headers.
7196 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

7200 directly accessing frame internals.
7202 * w32font.h: Include font.h. Define syms_of_w32font and
7205 * process.c: Include TERM_HEADER instead of listing all possible
7206 window-system headers.
7208 * nsterm.h: Remove declarations now in frame.h.
7209 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
7211 * menu.c: Include TERM_HEADER instead of listing all possible
7212 window-system headers.
7214 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
7217 * keyboard.c: Include TERM_HEADER instead of listing all possible
7218 window-system headers.
7220 * image.c: Include TERM_HEADER instead of listing all possible
7221 window-system headers. Declare Vlibrary_cache when compiling for
7224 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
7225 window system declarations.
7227 * frame.h: Move common functions here: set_frame_menubar,
7228 x_set_window_size, x_sync, x_get_focus_frame,
7229 x_set_mouse_position, x_set_mouse_pixel_position,
7230 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

7250 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
7251 the current window system; include in list of objects to link into
7254 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7256 Remove mark_ttys function and fix tty_display_info initialization.
7257 * lisp.h (mark_ttys): Remove prototype.
7258 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
7259 to mark_ttys because all possible values of 'top_frame' slot are
7260 the frames which are reachable from Vframe_list.
7261 * term.c (mark_ttys): Remove.
7262 (init_tty): Safely initialize 'top_frame' slot with Qnil.
7264 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7266 Change struct frame bitfields from unsigned char to unsigned.
7267 * frame.h (struct frame): Change type of 'display_preempted',
7268 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
7269 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
7270 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
7271 bitfields from unsigned char to unsigned.
7273 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7275 Remove unused member of struct x_output and struct w32_output.
7276 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
7277 * w32term.h (struct w32_output): Likewise.
7279 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
7281 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
7282 does not become zero (Bug#12234).
7284 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
7286 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
7287 for GCC 4.7.1 x86-64.
7289 2012-08-30 Glenn Morris <rgm@gnu.org>
7291 * lread.c (init_lread): For out-of-tree builds, only add the
7292 source directory's site-lisp dir to the load-path if it exists,
7293 consistent with in-tree builds. (Bug#12302)
7295 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
7297 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
7298 button_values to NULL. Call setStykeMask so dialogs get a close button.
7299 (windowShouldClose:): Set window_closed.
7300 (dealloc): New member, free button_values.
7301 (process_dialog:): Make member function. Remove window argument,
7302 replace window with self. Count buttons and allocate and store values
7304 (addButton:value:row:): value is int with the name tag. Call setTag
7305 with tag. Remove return self, declare return value as void.
7306 (addString:row:): Remove return self, declare return value as void.
7307 (addSplit): Remove return self, declare return value as void.
7308 (clicked:): Remove return self, declare return value as void.
7309 Set dialog_return to button_values[seltag]. Code formatting change.
7310 (initFromContents:isQuestion:): Adjust call to process_dialog.
7311 Code formatting change.
7312 (timeout_handler:): Set timer_fired to YES.
7313 (runDialogAt:): Set timer_fired to NO.
7314 Handle click on close button as quit.
7316 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7317 Add window_closed and button_values. Add void as return value for
7318 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7319 Add process_dialog as new member.
7321 2012-08-28 Eli Zaretskii <eliz@gnu.org>
7323 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
7324 is not one of the heaps we manage. (Bug#12242)
7326 2012-08-28 Glenn Morris <rgm@gnu.org>
7328 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
7330 2012-08-28 Martin Rudalics <rudalics@gmx.at>
7332 * window.c (Fset_window_configuration): Remove handling of
7333 auto-buffer-name window parameter. Install revision of reverted
7336 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
7338 Do not allow to set major mode for a dead buffer.
7339 * buffer.c (Fset_buffer_major_mode): Signal an error
7340 if the buffer is dead.
7341 (Fother_buffer, other_buffer_safely): Remove redundant
7344 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
7346 Always use set_buffer_if_live to restore original buffer at unwind.
7347 * buffer.h (record_unwind_current_buffer): New function.
7348 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
7349 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
7350 * undo.c, window.c: Adjust users.
7351 * buffer.c (set_buffer_if_live): Fix comment.
7353 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
7355 Fix usage of set_buffer_internal.
7356 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
7357 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
7358 * coding.c (decode_coding): Omit redundant test.
7359 * fileio.c (decide_coding_unwind): Likewise.
7360 * fns.c (secure_hash): Likewise.
7361 * insdel.c (modify_region): Likewise.
7362 * keyboard.c (command_loop_1): Likewise.
7363 * print.c (PRINTFINISH): Likewise.
7364 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
7366 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

7386 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
7387 and remove last int (actually boolean) argument, which was always 0.
7388 All callers changed.
7389 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
7390 * dispextern.h (struct composition_it): Use bool for boolean.
7391 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
7392 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
7393 * dired.c (file_name_completion):
7394 Use bool for boolean. (This was missed in an earlier change.)
7396 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7398 * window.c (Fset_window_configuration): Revert first part of
7401 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
7403 * nsterm.h (NSPanel): New class variable dialog_return.
7405 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
7406 Initialize dialog_return.
7407 (windowShouldClose:): Use stop instead of stopModalWithCode.
7408 (clicked:): Ditto, and also set dialog_return (Bug#12258).
7409 (timeout_handler:): Use stop instead of abortModal. Send a dummy
7411 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

7456 Use bool for booleans.
7457 * coding.h, lisp.h: Reflect above API changes.
7458 * coding.c: Remove unnecessary static function decls.
7459 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
7460 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
7461 not a boolean 'int', since callers never look at the return value.
7462 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
7463 * coding.h (decoding_buffer_size, encoding_buffer_size)
7464 (emacs_mule_string_char): Remove unused extern decls.
7465 (struct iso_2022_spec, struct coding_system):

7467 (struct emacs_mule_spec): Remove unused field 'full_support'.
7468 All initializations removed.
7469 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
7471 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7473 Fix spare memory change (Bug#12286).
7474 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7475 (valid_lisp_object_p): Likewise.
7477 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7479 * window.c (Fset_window_configuration): Record any window's old
7480 buffer if it's replaced (see Bug#8789). If the new current
7481 buffer doesn't appear in the selected window, go to its old
7484 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7486 Special MEM_TYPE_SPARE to denote reserved memory.
7487 * alloc.c (enum mem_type): New memory type.
7488 (refill_memory_reserve): Use new type for spare memory.
7489 This prevents live_cons_p and live_string_p from incorrect
7490 detection of uninitialized objects from spare memory as live.
7492 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7495 * Makefile.in (.PHONY): versioclean -> versionclean.
7497 Remove unused external symbols.
7498 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7499 * window.c (Qwindow_valid_p, decode_valid_window):
7500 Now static, not extern.
7501 * data.c (Qinterval): Remove; unused.
7502 (syms_of_data): Do not define 'interval'.
7503 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7504 * window.h (decode_valid_window):
7507 * character.c, charset.c, chartab.c: Use bool for booleans.

7517 (char_table_set_range, optimize_sub_char_table)
7518 (map_sub_char_table):
7519 Use bool for boolean.
7520 * character.c (str_to_unibyte): Omit last boolean argument; it was
7521 always 0. All callers changed.
7522 * character.h, charset.h: Adjust to match previous changes.
7523 * character.h (char_printable_p): Remove decl of nonexistent function.
7524 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7525 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7526 are all boolean, so make them single-bit bitfields.
7528 * lisp.h (ASET): Remove attempt to detect side effects.
7529 It was meant to be temporary and it often doesn't work,
7530 because when IDX has side effects the behavior of IDX==IDX
7531 is undefined. See Stefan Monnier in
7532 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7534 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7536 * lisp.h (functionp): New function (extracted from Ffunctionp).
7537 (FUNCTIONP): Use it.
7538 * eval.c (Ffunctionp): Use it.
7540 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7542 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7543 as that's faster and simpler than static storage. Don't bother
7544 with the g_main_context_query overhead if g_main_context_pending
7545 says no events are pending.
7546 (gfds, gfds_size): Remove these static vars.
7547 (xgselect_initialize): Remove; no longer needed.
7548 All uses and decls removed.
7550 * emacs.c (fatal_error_signal_hook): Remove.
7551 All uses removed. This leftover from old code was always 0.
7553 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7554 * casefiddle.c (casify_object, casify_region):
7555 * casetab.c (set_case_table):
7556 * category.c, category.h (word_boundary_p):
7557 * category.h (CHAR_HAS_CATEGORY):
7558 Use bool for booleans, instead of int.
7560 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7562 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7564 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7566 On assertion failure, print backtrace if available.
7567 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7568 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7569 * Makefile.in (LIB_EXECINFO): New macro.
7572 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7573 * bytecode.c (exec_byte_code):
7574 * callint.c (check_mark, Fcall_interactively):
7575 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7576 (getenv_internal, sync_process_alive, call_process_exited):
7577 * lisp.h (USE_SAFE_ALLOCA):
7578 Use bool for booleans, instead of int.
7579 * lisp.h, process.h: Adjust prototypes to match above changes.
7580 * callint.c (Fcall_interactively): Don't assume the mark's
7581 offset fits in 'int'.
7583 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7585 * buffer.c, buffer.h: Use bool for boolean.
7586 * buffer.c (reset_buffer_local_variables)

7592 (mmap_enlarge, mmap_set_vars):
7593 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7594 Use bool for booleans, instead of int.
7595 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7596 since the 1-or-0 return value is always ignored anyway.
7597 (mmap_initialized_p):
7598 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7599 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7601 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7603 * bidi.c: Use bool for boolean.
7604 This is a bit more readable, and makes the text segment of bidi.o
7605 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7606 Presumably it's faster too.
7607 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

7612 (bidi_explicit_dir_char, bidi_level_of_next_char)
7613 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7614 Use bool for booleans, instead of int.
7615 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7616 (bidi_unshelve_cache): Adjust decls to match code.
7618 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7620 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7623 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7625 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7626 * atimer.h: Include <stdbool.h>.
7628 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7630 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7631 compile time tests instead of run time tests on systems that do
7633 (FRAME_MAC_P): Remove leftover from deleted code.
7634 * frame.c (syms_of_frame): Remove leftover from deleted code.
7636 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7638 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7640 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7642 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7643 Otherwise, the compiler complains about (A?B:C) where B is void
7644 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7645 (fontset_add): Return void, for FONTSET_ADD.
7647 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7649 * alloc.c: Use bool for booleans.
7650 (gc_in_progress, abort_on_gc)
7651 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7652 (dont_register_blocks) [GC_MALLOC_CHECK]:
7653 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.

7655 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7656 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7657 (mark_stack, valid_pointer_p, make_pure_string)
7658 (Fgarbage_collect, survives_gc_p, gc_sweep):
7659 Use bool for booleans, instead of int.
7660 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7661 Remove unused local.
7662 * alloc.c (PURE_POINTER_P):
7663 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7664 * editfns.c (Fformat):
7665 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7667 * fns.c (sweep_weak_table):
7668 * lisp.h (suppress_checking, push_message, survives_gc_p)
7669 (make_pure_string, gc_in_progress, abort_on_gc):
7670 * lread.c (readchar, read1):
7671 * print.c (Fprin1_to_string):
7672 * xdisp.c (push_message):
7673 Use bool for booleans affected directly or indirectly by
7676 Make recently-introduced setters macros.
7677 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7678 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7679 (set_fontset_default, set_fontset_fallback): Rename from their
7680 upper-case counterparts, and make them functions rather than macros.
7681 This is more consistent with the other recently-introduced setters.
7682 These don't need to be inline, since they're local.
7684 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7686 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7687 the loop (Bug#12247).
7689 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7691 * lisp.h (vcopy): Use memcpy rather than our own loop.
7692 This fixes a performance regression introduced by the recent
7693 addition of vcopy. This means 'vcopy' will need to be modified
7694 for a copying collector, but that's OK. Also, tighten the
7695 checking in the assertion.
7697 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7699 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7700 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7701 non-base glyph for the width of the base character, according to
7702 what x_draw_composite_glyph_string_foreground expects.
7703 Generate WADJUST value according to composition_gstring_width's
7704 expectations, to produce correct width of the composed character.
7705 Reverse the sign of the DU offset produced by ScriptPlace.
7707 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7709 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7711 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7713 Avoid direct writes to contents member of struct Lisp_Vector.
7714 * lisp.h (vcopy): New function to copy data into vector.
7715 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7716 * fns.c (Ffillarray): Use ASET.
7717 * keyboard.c (timer_check_2): Use AREF and ASET.
7718 (append_tool_bar_item, Frecent_keys): Use vcopy.
7719 * lread.c (read_vector): Use ASET.
7720 * msdos.c (Frecent_doskeys): Use vcopy.
7721 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7722 (Finternal_merge_in_global_face): Use ASET and vcopy.
7723 * xfont.c (xfont_list_pattern): Likewise.
7725 2012-08-21 Martin Rudalics <rudalics@gmx.at>

7791 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7793 Rely on <config.h> + <unistd.h> to declare 'environ',
7794 as gnulib does this if the system doesn't.
7795 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

8664 2012-08-04 Eli Zaretskii <eliz@gnu.org>
8666 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
8667 * w32.c (init_environment): Change the default values of many
8668 environment variables in dflt_envvars[] to NULL, to avoid pushing
8669 them into environment when they were not already defined.
8670 Remove the code that deletes site-lisp subdirectories from the default
8671 value of EMACSLOADPATH, as it is no longer needed.
8672 (check_windows_init_file): Now external, not static.
8673 Use Vload_path as is, without adding anything, as this function is now
8674 called when Vload_path is already set up.
8676 * w32.h (check_windows_init_file): Add prototype.
8678 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
8679 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
8680 compatibility with Posix platforms.
8681 (main): Move the call to check_windows_init_file to here from
8683 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
8684 any, in the DEFALT argument into the root of the Emacs build or
8685 installation tree, as appropriate.
8687 * callproc.c (init_callproc_1): Call decode_env_path instead of
8688 doing its equivalent by hand.
8689 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
8690 the code that sets Vexec_path run on MS-Windows.
8692 * lread.c (init_lread): Add comments to #ifdef's.
8694 * msdos.c (dos_set_window_size, IT_update_begin)

8701 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
8702 Now constants, not macros.
8704 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
8706 Remove unnecessary casts involving pointers.
8707 These casts are no longer needed now that we assume C89 or later,
8708 since they involve casting to or from void *.
8709 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
8710 (make_pure_float, make_pure_vector):
8711 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

8720 (x_get_window_property, x_get_window_property_as_lisp_data):
8721 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8722 Remove unnecessary pointer casts.
8723 * alloc.c (record_xmalloc): New function.
8724 * lisp.h (record_xmalloc): New decl.
8725 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8726 more like a function. This is because the pointer cast is not
8727 needed. All uses changed.
8728 * print.c (print_string, print_error_message): Avoid length recalc.
8730 Improve fix for macroexp crash with debugging (Bug#12118).
8731 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8732 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8733 not supposed to be invoked from the garbage collector.
8734 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
8735 (gc_aset): New function, which is like ASET but can be
8736 used in the garbage collector.
8737 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

8749 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
8750 (map_w32_filename): Improve commentary. Simplify switch.
8751 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
8752 headers (most versions of MinGW w32api don't).
8753 (get_security_info, create_symbolic_link)
8754 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
8756 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
8757 in the argument file name.

8760 (sys_rename): Diagnose renaming of a symlink when the user doesn't
8761 have the required privileges.
8762 (get_file_security_desc_by_name): Rename from
8763 get_file_security_desc.

8765 with addition of handling of symlinks and support for 'lstat'.
8766 If possible, get file's attributes and security information by
8767 handle, not by name. Produce S_IFLNK bit for symlinks, when
8768 called from 'lstat'.
8769 (stat, lstat): New functions, call 'stat_worker'.
8770 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8771 symlinks when the underlying filesystem supports them.
8773 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8775 Fix macroexp crash on Windows with debugging (Bug#12118).
8776 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8777 checking subscripts; problem introduced with the recent
8778 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8779 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8780 since it's used in non-static inline functions now.
8782 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8783 Don't assume buffer size fits in 'int'. Remove unused local.

8801 * character.c (CHARACTER_INLINE):
8802 * charset.c (CHARSET_INLINE):
8803 * composite.c (COMPOSITE_INLINE):
8804 * dispnew.c (DISPEXTERN_INLINE):
8805 * sysdep.c (SYSTIME_INLINE):
8806 Define to EXTERN_INLINE, so that the corresponding functions
8807 are compiled into code.
8808 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8809 (INLINE_HEADER_END): New macros.
8810 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8832 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8834 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8835 This how ASET and AREF are supposed to work, and makes
8836 it easier to think about future improvements. See
8837 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8838 * charset.h (set_charset_attr): New function.

9091 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
9092 does that unconditionally. Remove file, which is now empty.
9094 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
9097 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

9215 * w32inevt.c: Include w32inevt.h.
9216 (w32_read_console_input): New inline function, calls either
9217 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
9218 w32_console_unicode_input.
9219 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
9220 (w32_kbd_patch_key, key_event): Use the codepage returned by
9221 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

9250 * alloc.c (listn): Fix the order the arguments are consed onto the
9253 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
9254 enumeration constants, as PURE and HEAP are too general, and clash
9255 with other headers and sources, such as gmalloc.c and the
9256 MS-Windows system headers. All users changed.
9258 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9260 Revert last save_excursion_save and save_excursion_restore changes.
9261 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

9271 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
9273 Improve GDB symbol export (Bug#12036).
9274 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
9275 arms of an 'if', not using conditional expressions; otherwise GDB
9276 complains about the types in the unevaluated arm when the argument
9277 is an integer literal.
9278 (xgetint): Simplify expression.
9279 * alloc.c (gdb_make_enums_visible): New constant. This ports to
9280 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
9281 Zaretskii in <http://bugs.gnu.org/12036#13>.
9282 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
9283 needed now that we have gdb_make_enums_visible.
9284 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
9285 (enum enum_USE_LSB_TAG):
9286 New enum types, packaging up enums that need to be exported to GDB.

9305 * xfns.c (syms_of_xfns): Likewise.
9307 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

9310 * lisp.h (struct Lisp_Excursion): New data type.
9311 (PVEC_EXCURSION): New pseudovector type.
9312 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
9313 to deal with it. Adjust comments.

9327 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
9328 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9329 emacs.c, as this is a more-suitable home. Had this been done earlier
9330 the fix for 12036 would have avoided some of the problems noted in
9331 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9332 would have been more obvious.
9333 * emacs.c: Do not include <verify.h>; no longer needed.
9334 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9335 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9336 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9337 Remove; now done in lisp.h.

9342 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9343 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9344 not be usable in #if. This simplifies things.
9346 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9348 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9350 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

9353 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9354 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9355 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9356 Adjust to changes in lisp.h and emacs.c, by using
9357 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9358 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9359 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9360 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9361 instead of gdb_valbits.
9362 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9363 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9364 instead of gdb_array_mark_flag.
9365 (xboolvector): Get size from $->size, not $->header.size.
9366 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9367 (xreload, hook-run, hookpost-run): Remove.
9368 * emacs.c: Include <verify.h>.
9369 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9370 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9372 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9373 (gdb_USE_LSB_TAG): New enum constants.
9374 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9375 Also define these as enum constants, so they're visible to GDB.
9376 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9377 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9378 as constants, so they're visible to GDB.
9379 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
9380 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9381 Now enum constants, not macros, so they're visible to GDB.
9382 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9383 more convenient now. All uses changed.
9384 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9385 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9387 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
9389 Explicitly free restriction data that are not needed anymore.
9390 * editfns.c (save_restriction_restore): Free restriction data.
9392 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
9394 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9395 add argument, tune behavior, and adjust all callers.
9397 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9399 Use typedef for EMACS_INT, EMACS_UINT.
9400 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9401 than macros. This simplifies debugging in the usual case, since
9402 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9403 and it allows expressions involving EMACS_INT casts.
9404 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9406 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

9414 that FOCUS-FRAME can be omitted.
9416 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9418 Adjust buffer text indirection counters at the end of Fkill_buffer.
9419 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9420 buffer is definitely dead. This should really fix an issue reported
9421 by Christoph Scholtes again. (Bug#12007).
9422 (init_buffer_once): Initialize indirection counters of
9423 buffer_defaults and buffer_local_symbols (for sanity and safety).
9425 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9427 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9428 and continuation glyphs on tooltip frames, leave them at zero.
9429 Avoids continued lines in tooltips. (Bug#11832)
9431 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
9433 Simplify copy_overlay.
9434 * buffer.c (copy_overlay): Simplify. Use build_marker.

9440 or invalid. (Bug#12025)
9442 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
9443 it signals an error when a tooltip frame is being created.
9445 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9447 Cleanup miscellaneous objects allocation and initialization.
9448 * alloc.c (allocate_misc): Change to static. Add argument to
9449 specify the subtype. Adjust comment and users.
9450 (build_overlay): New function.
9451 * buffer.c (copy_overlays, Fmake_overlay): Use it.
9452 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
9453 (allocate_misc): Remove prototype.
9454 (build_overlay): Add prototype.
9456 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9458 Swap buffer text indirection counters in Fbuffer_swap_text.
9459 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9460 This avoids crash reported by Christoph Scholtes at
9461 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9463 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9465 * nsmenu.m (Popdown_data): New struct.
9466 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
9468 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
9469 (initWithContentRect): Make imgView and contentView non-static
9470 and autorelease them. Also autorelease img and matrix (Bug#12005).
9471 (dealloc): Remove (Bug#12005).
9473 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9475 Adjust consing_since_gc when objects are explicitly freed.
9476 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
9477 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
9478 (free_cons, free_misc): Subtract object size from consing_since_gc.
9480 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>

10219 * s/aix4-2.h (unix): Remove; no longer needed.
10221 EMACS_TIME simplification (Bug#11875).
10222 This replaces macros (which typically do not work in GDB)

10224 The functional style also makes code easier to read and maintain.
10225 * systime.h: Include <sys/time.h> on all hosts, not just if
10226 WINDOWSNT, since 'struct timeval' is needed in general.
10227 (EMACS_TIME): Now a typedef, not a macro.

10261 (menu_separator_name_p):
10262 * nsmenu.m (ns_update_menubar):
10263 Prefer memcmp to strncmp when either will do.
10264 * nsterm.m: Include <ftoastr.h>.
10266 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10267 Prefer snprintf to strncpy.
10268 * nsterm.m (ns_term_init):
10269 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10270 * nsterm.m (ns_term_init):
10271 Avoid the need for strncpy, by using build_string or
10272 make_unibyte_string directly. Use dtoastr, not snprintf.
10273 * process.c (Fmake_network_process): Diagnose service names that
10274 are too long, rather than silently truncating them or creating
10275 non-null-terminated names.
10276 (Fnetwork_interface_info): Likewise, for interface names.
10277 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10278 Prefer sprintf to strncat.
10279 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
10280 Prefer vsnprintf to vsprintf + strncpy.

10291 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10292 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
10293 where argument type is known to be a Lisp_Cons.

10307 (build_pure_c_string): New function, defined as static inline. This
10308 provides a better opportunity to optimize away calls to strlen when
10309 the function is called with compile-time constant argument.
10310 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10311 argument, adjust users accordingly. Use build_pure_c_string where

10314 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10315 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

10342 * s/gnu.h (DATA_START): Move definitions to configure.
10344 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10345 We include usg5-4-common.h, which defines them both.
10347 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10348 O_RDONLY already includes it).
10350 Stop ns builds setting the EMACSLOADPATH environment variable.
10351 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10352 Now it does not set EMACSLOADPATH, just returns the load-path string.
10353 * nsterm.h: Update accordingly.
10354 * lread.c [HAVE_NS]: Include nsterm.h.
10355 (init_lread) [HAVE_NS]: Use ns_load_path.

10358 2012-07-09 Glenn Morris <rgm@gnu.org>
10360 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10361 since the included bsd-common.h does so.
10363 Stop ns builds setting the EMACSPATH environment variable.
10364 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10365 (ns_init_paths): Do not set EMACSPATH.

10367 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10370 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10372 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10374 * process.c (wait_reading_process_output): 'waitchannels' was unset
10375 when read_kbd || !NILP (wait_for_cell); fix this.
10377 Add GCC-style 'const' attribute to functions that can use it.
10378 * character.h (char_resolve_modifier_mask):
10379 * keyboard.h (make_ctrl_char):
10380 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10381 (init_character_once, next_almost_prime, init_fns, init_image)
10382 (flush_pending_output, init_sound):
10383 * mem-limits.h (start_of_data):
10384 * menu.h (finish_menu_items):

10389 Add decls with ATTRIBUTE_CONST.
10391 Minor improvements to make_formatted_string.
10392 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10393 where int is good enough, as vsprintf returns an int.
10394 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10396 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10398 Use make_formatted_string to avoid double length calculation.
10399 * lisp.h (make_formatted_string): New prototype.
10400 * alloc.c (make_formatted_string): New function.
10401 * buffer.c (Fgenerate_new_buffer_name): Use it.
10402 * dbusbind.c (syms_of_dbusbind): Likewise.

10407 * image.c (gs_load): Likewise.
10408 * minibuf.c (get_minibuffer): Likewise.

10421 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10423 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10425 Move marker debugging code under MARKER_DEBUG.
10426 * marker.c (MARKER_DEBUG): Move marker debugging code under
10427 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10428 for bootstrap with --enable-checking (~3x slowdown reported
10429 by Juanma Barranquero <lekktu@gmail.com>).
10430 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10432 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10434 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10435 See <http://bugs.gnu.org/11825#29>.
10437 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10439 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10440 has no font, use the frame's font. (Bug#11813)
10441 (display_line): Add commentary about displaying truncation glyphs
10443 (produce_special_glyphs): Move here from term.c.
10445 * term.c (produce_special_glyphs): Move to xdisp.c.
10447 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10450 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10452 * xdisp.c (display_line): Avoid warning about implicit declaration
10455 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10457 * lisp.h: Remove empty conditional.
10459 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10461 * lread.c (load_path_check): Now static.
10463 Fix some minor --with-ns problems found by static checking.
10464 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10465 (x_set_font) [!HAVE_X_WINDOWS]:
10466 * image.c (xpm_load_image) [HAVE_NS]:
10467 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10468 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10469 Remove unused local.
10470 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10471 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10472 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10473 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10474 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10475 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10476 Fix pointer signedness problem.
10477 * xfaces.c (FRAME_X_FONT_TABLE):
10478 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10480 2012-07-07 Glenn Morris <rgm@gnu.org>
10482 * lread.c (load_path_check): New function, split from init_lread.
10483 (init_lread): Reorganize. Motivation:
10484 If EMACSLOADPATH is set, check/warn about that rather than the
10485 defaults, which we are not going to use. Hence we can remove
10486 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10487 Don't warn if site-lisp directories are missing.
10488 If not installed, start from a blank load-path, since
10489 PATH_LOADSEARCH refers to the eventual installation directories.
10491 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10493 Support truncation and continuation glyphs on GUI frames, when
10494 fringes are disabled. (Bug#11832)
10495 * xdisp.c (init_iterator): Get dimensions of truncation and
10496 continuation glyphs even if on GUI frames.
10497 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10498 or both, are absent.
10499 (start_display, move_it_in_display_line_to): Handle the case of a
10500 GUI frame without a fringe to display continuation or truncation
10502 (insert_left_trunc_glyphs): Support GUI frames: make sure
10503 truncation glyphs overwrite enough glyphs from the current line to
10504 have sufficient space in pixels.
10505 (display_line): Support truncation and continuation glyphs on GUI
10506 frames. If some spare pixels are left on the line after inserting
10507 the truncation glyphs, fill that space with a stretch glyph of a
10508 suitably computed width.
10510 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10511 produce_glyphs, to support GUI sessions.
10513 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10515 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10517 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10519 Do not require float-time's arg to fit in time_t (Bug#11825).
10520 This works better on hosts where time_t is unsigned, and where
10521 float-time is applied to the (negative) difference between two times.
10522 * editfns.c (decode_time_components): Last arg is now double *,
10523 not int *, and means to store all the result as a double, without
10524 worrying about whether the seconds part fits in time_t.
10525 All callers changed.
10526 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10527 All callers changed.
10528 (Ffloat_time): Do not fail merely because the specified time falls
10529 outside of time_t range.
10531 2012-07-07 Glenn Morris <rgm@gnu.org>
10533 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10534 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10535 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10537 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10539 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10540 Update dependencies.
10542 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10544 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

10548 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10549 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10550 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10551 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10553 * xfont.c (compare_font_names): Redo to omit the need for casts.
10555 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10557 * xfns.c (Fx_change_window_property): Doc fix.
10558 * w32fns.c (Fx_change_window_property): Doc fix.
10560 * w32fns.c (Fx_window_property): Accept the same arguments as the
10561 X Windows version. Doc fix.
10562 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10564 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10565 Eli Zaretskii <eliz@gnu.org>
10567 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10568 Windows-specific code from nt/config.nt moved here.
10569 Obsolete settings removed.
10571 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10573 * process.c: Avoid unnecessary calls to gettime.
10574 (wait_reading_process_output): Don't get the time of day
10575 when gobbling data immediately and not waiting, as there's no need
10576 for it in that case. This removes a FIXME.
10578 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10580 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10581 is defined (Bug#11768).
10583 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10585 Fix marker debugging code.
10586 * marker.c (byte_char_debug_check): Do not perform the check
10587 if buffer is not multibyte.
10588 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10589 Call byte_char_debug_check with correct arguments.
10591 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10593 Compile marker debugging code only if ENABLE_CHECKING is defined.
10594 * marker.c (byte_char_debug_check, count_markers):
10595 Use only if ENABLE_CHECKING is defined.
10596 (byte_debug_flag): Remove.
10597 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10598 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10600 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10602 Avoid code repetition in marker-related functions.
10603 * marker.c (attach_marker): New function.
10604 (Fset_marker, set_marker_restricted, set_marker_both)

10607 Consistently rename charno to charpos.
10608 (marker_position): Add eassert.
10609 (marker_byte_position): Convert to eassert.

10625 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10626 (save_restriction_save): Use build_marker.
10627 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10628 * window.c (save_window_save): Likewise.
10630 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10632 Do not use Fdelete_overlay in delete_all_overlays
10633 to avoid redundant calls to unchain_overlay.
10634 * buffer.c (drop_overlay): New function.
10635 (delete_all_overlays, Fdelete_overlay): Use it.
10636 * minibuf.c (get_minibuffer): Fix comment.
10638 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10640 Port to OpenBSD 5.1 amd64.
10641 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10642 This is needed for OpenBSD, and should be harmless on all BSD systems.
10643 Also, include <sys/sysctl.h>, as it should be available on all
10644 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10645 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10646 use p_pid member, not kp_proc.pid.
10648 2012-07-06 Glenn Morris <rgm@gnu.org>
10650 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10652 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10654 More xmalloc and related cleanup.
10655 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
10656 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
10657 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

10663 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10665 Omit needless casts involving void * pointers and allocation.
10666 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10667 as the former is more robust if P's type is changed.
10668 Prefer xzalloc to xmalloc + memset 0.
10669 Simplify malloc-or-realloc to realloc.
10670 Don't worry about xmalloc returning a null pointer.
10671 Prefer xstrdup to xmalloc + strcpy.
10672 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10674 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10675 alloca of a constant.
10677 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10679 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10680 hscroll is larger than the line width. Fixes long and futile
10681 looping inside extend_face_to_end_of_line (on a TTY) producing
10682 glyphs that are not needed and thrown away.
10684 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10686 * marker.c (set_marker_restricted_both): Simplify by using
10689 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

10700 followed by gtk_box_set_homogeneous (Bug#11768).
10701 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10702 (update_theme_scrollbar_width, xg_create_scroll_bar):
10703 Use gtk_scrollbar_new (Bug#11768).
10704 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
10705 (is_box_type): New function (Bug#11768).
10706 (xg_tool_item_stale_p): Call is_box_type.
10707 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10708 with default display (Bug#11768).
10710 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10712 * xdisp.c (window_hscroll_limited): New function.
10713 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10714 coordinates when window's hscroll is set to insanely large
10715 values. (Bug#11857)
10717 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
10719 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

10778 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10780 * fileio.c (time_error_value): Check the right error number.
10781 Problem reported by Troels Nielsen in
10782 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10784 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10786 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10787 This should be fixed in a better way; see Eli Zaretskii in
10788 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10789 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10791 * fileio.c (time_error_value): Rename from special_mtime.
10792 The old name's problems were noted by Eli Zaretskii in
10793 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10795 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10796 This variable's comment says Emacs needs at least one GDB-visible
10797 symbol of type enum pvec_type, to work around GDB problems.
10798 The symbol's value doesn't matter.
10800 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10801 that causes compilation to fail on pre-C99 compilers.
10803 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10805 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

10808 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10810 * buffer.c (init_buffer_once): Fix initialization of
10811 headers for buffer_defaults and buffer_local_symbols.
10812 Reported by Juanma Barranquero <lekktu@gmail.com>.

10818 (PSEUDOVECTOR_SIZE_BITS): New constant.
10819 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10820 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10821 change in pvec_type.
10822 (PSEUDOVECTOR_TYPEP): New macro.
10823 (TYPED_PSEUDOVECTORP): Use it.
10824 * fns.c (internal_equal): Adapt code to extract pvectype.
10825 * emacs.c (gdb_pvec_type): Update type.
10826 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10827 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10828 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10829 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10830 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10831 abusing vector->header.next.nbytes.
10832 (live_vector_p): Use PVEC_TYPE.
10833 (mark_object): Adapt code to extract pvectype. Use switch.
10835 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10837 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10838 Tighten new eassert a bit.
10840 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10842 Fix compilation with --enable-gcc-warnings and -O1
10843 optimization level.
10844 * doprnt.c (doprnt): Change type of tem to int, initialize
10845 to avoid compiler warning. Add eassert.
10846 * search.c (simple_search): Initialize match_byte to avoid
10847 compiler warning. Add eassert.
10849 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10851 Avoid weird behavior with large horizontal scrolls.
10852 Without this change, for example, large hscroll values would
10853 mess up Emacs's display on Fedora 15 x86, presumably due to
10854 overflows in int calculations in the display code.
10855 Also, if buffers had long lines, Emacs would freeze.
10856 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10857 (set_window_hscroll): New function, containing the old guts of
10858 Fset_window_hscroll. Return the clipped value.
10859 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10860 This avoids the need to check against PTRDIFF_MAX.
10862 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10864 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10866 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10868 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10870 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10871 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10872 since GCC 4.4.6 issues a bogus warning for them.
10874 Fix bugs in file timestamp newness comparisons.
10875 * fileio.c (Ffile_newer_than_file_p):
10876 * lread.c (Fload): Use full timestamp resolution of files,
10877 not just the 1-second resolution, so that files that are only
10878 slightly newer still count as newer.
10879 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10880 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10882 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10884 * fileio.c: Improve handling of file time marker. (Bug#11852)
10885 (special_mtime): New function.
10886 (Finsert_file_contents, Fverify_visited_file_modtime):
10887 Use it to set special mtime values consistently.
10889 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10891 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10892 marker for non-existing file. (Bug#11852)
10894 2012-07-03 Glenn Morris <rgm@gnu.org>
10896 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10897 and did not make it into globals.h).
10899 2012-07-03 Tom Tromey <tromey@redhat.com>
10901 * window.c (Fset_window_margins, Fset_window_fringes)
10902 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10903 * textprop.c (Fprevious_property_change): No longer static.

10928 * font.h: Remove EXFUNs.
10929 * dosfns.c (system_process_attributes): Remove EXFUN.
10930 * keymap.h: Remove EXFUNs.
10931 * lisp.h: Remove EXFUNs.
10932 * w32term.h: Remove EXFUNs.
10933 * window.h: Remove EXFUNs.
10934 * xsettings.h: Remove EXFUN.
10935 * xterm.h: Remove EXFUN.
10937 2012-07-03 Glenn Morris <rgm@gnu.org>
10939 * lisp.h (Frandom): Make it visible to C.
10940 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10941 buffer for invisible buffers. (Bug#1229)
10943 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10945 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10946 values which aren't power of 2.
10947 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10948 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10951 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10953 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10955 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10957 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10959 * alloc.c (allocate_vector_block): Remove redundant
10960 calls to mallopt if DOUG_LEA_MALLOC is defined.
10961 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10962 avoid calls to mallopt if zero_vector is returned.
10964 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10966 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10967 is enabled, avoid dereferencing NULL current_sblock if
10970 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10972 Cleanup basic buffer management.
10973 * buffer.h (struct buffer): Change layout to use generic vector
10974 marking code. Fix some comments. Change type of 'clip_changed'
10975 to bitfield. Remove unused #ifndef old.
10976 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10977 (GET_OVERLAYS_AT): Fix indentation.
10978 (for_each_per_buffer_object_at): New macro.
10979 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10980 (Fbuffer_local_variables): Use it.
10981 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.

10983 struct buffer. Fix comment.
10984 (mark_overlay): New function.
10985 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10986 Lisp area of struct buffer.
10987 (mark_object): Use it. Adjust marking of misc objects
10988 and related comments.
10990 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10992 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10993 wrapper that is not needed because the wrapped code is a no-op (zero
10994 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10995 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10997 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10999 * alloc.c (mark_buffer): Simplify. Remove prototype.
11000 (mark_object): Add comment. Reorganize marking of vector-like
11001 objects. Use CHECK_LIVE for all vector-like objects except buffers
11002 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11003 Avoid redundant calls to mark_vectorlike for bool vectors.
11005 2012-06-30 Glenn Morris <rgm@gnu.org>
11007 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11009 * epaths.in (PATH_SITELOADSEARCH): New.
11010 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11011 This is rather than relying on --enable-locallisppath elements
11012 having "site-lisp" in their names. (Bug#10208#25, 11658)
11014 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11016 * w32proc.c (sys_select): Accept and ignore one more argument.
11018 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11020 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11021 (pselect) [!MS_DOS]: Redirect to sys_select.
11023 * sysdep.c: Don't include dos.h and dosfns.h.
11025 * process.c (sys_select):
11026 * msdos.c (sys_select): Accept one more argument and ignore it.
11028 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11029 adapt data types and code to that.
11032 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11033 which clashes with the gnulib function of the same name.
11035 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11037 * font.c (font_style_to_value, font_style_symbolic)
11038 (font_prop_validate_style): Add type checks for values in
11041 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11043 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11046 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11048 * xdisp.c (try_window_id): Undo last change.
11050 * w32.c (getwd): Adjust commentary about startup_dir.
11051 (init_environment): Always call sys_access, even in non-MSVC
11052 builds. Don't chdir to the directory of the Emacs executable.
11053 This undoes code from 1997 which was justified by the need to
11054 "avoid conflicts when removing and renaming directories". But its
11055 downside was that every relative file name was being interpreted
11056 relative to the directory of the Emacs executable, which can never
11057 be TRT. In particular, it broke sys_access when called with
11058 relative file names.
11059 (sys_access): Map GetLastError to errno.
11061 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11063 * window.h (struct window): Change type of 'fringes_outside_margins'
11064 to bitfield. Fix comment. Adjust users accordingly.
11065 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
11067 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11070 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11072 * gnutls.c (emacs_gnutls_handshake):
11073 Add QUIT to make the loop interruptible.
11075 2012-06-29 Glenn Morris <rgm@gnu.org>
11077 * charset.c (init_charset): Make lack of etc/charsets fatal.
11079 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

11085 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11086 undefined. Convert from xassert to eassert.
11087 * nsmenu.m: Convert from xassert to eassert.
11088 * nsterm.m: Likewise.
11090 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
11092 * editfns.c (region_limit): Clip to narrowing (bug#11770).
11094 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11096 Avoid integer overflow on scroll-left and scroll-right.
11097 * window.c (HSCROLL_MAX): New macro.
11098 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11099 overflow when requested scroll falls outside ptrdiff_t range.
11101 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11103 * window.h (struct window): Change type of 'hscroll',
11104 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11105 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11106 Adjust users accordingly.
11107 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11108 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11109 from EMACS_INT to ptrdiff_t.
11110 (make_window): Omit redundant initialization.
11112 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

11129 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11130 adjust comments accordingly.

11212 when building with Clang.

11251 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11253 Use sprintf return value instead of invoking strlen on result.
11254 In the old days this wasn't portable, since some sprintf
11255 implementations returned char *. But they died out years ago and
11256 Emacs already assumes sprintf returns int.
11257 Similarly for float_to_string.
11258 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
11259 * ccl.c (ccl_driver):
11260 * character.c (string_escape_byte8):

11263 * print.c (print_object):
11264 * xdisp.c (message_dolog):
11265 * xfns.c (syms_of_xfns):
11266 Use sprintf or float_to_string result to avoid need to call strlen.
11267 * data.c (Fnumber_to_string):
11268 Use make_unibyte_string, since the string must be ASCII.
11269 * lisp.h, print.c (float_to_string): Now returns int length.
11270 * term.c (produce_glyphless_glyph):
11271 Use sprintf result rather than recomputing it.
11273 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
11274 * Makefile.in (ALL_CFLAGS):

11311 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11312 instead of truncating it to 63 (admittedly a generous limit).
11314 * process.c: Fix spelling and caps in comments.

11367 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11369 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
11370 * lisp.h (WAIT_READING_MAX): New macro.
11371 * dispnew.c (Fsleep_for, sit_for):
11372 * keyboard.c (kbd_buffer_get_event):
11373 * process.c (Faccept_process_output):
11374 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11375 This improves on the previous patch, which introduced a bug
11376 when time_t is unsigned and as wide as intmax_t.
11377 See <http://bugs.gnu.org/9000#51>.
11379 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11408 language ID in the event parameters.
11410 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11411 event.code, not the obscure "character set ID".
11413 2012-06-23 Chong Yidong <cyd@gnu.org>
11415 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

11442 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
11444 Support higher-resolution time stamps (Bug#9000).
11445 The time stamps are only nanosecond-resolution at the C level,
11446 since that's the best that any real-world system supports now.
11447 But they are picosecond-resolution at the Lisp level, as that's
11448 easy, and leaves room for future OS improvements.
11450 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11453 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11454 Don't get current time unless it's needed.
11456 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11457 now provides it if it's absent.
11458 (start_atimer): Port to higher-res time stamps.
11459 Check for time stamp overflow. Don't get current time more
11460 often than is needed.
11462 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11463 Include systime.h, not time.h.
11464 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11466 * dired.c: Include stat-time.h.
11467 (Ffile-attributes): File times now have higher resolution.
11469 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11470 (struct image): Timestamp now has higher resolution.
11472 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11473 has at least microseconds now. All uses removed.
11474 (update_frame, update_single_window, update_window, update_frame_1)
11475 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11476 (duration_to_sec_usec): Remove; no longer needed.
11478 * editfns.c (time_overflow): Now extern.
11479 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
11480 (float-time, Fformat_time_string, Fcurrent_time_string)

11484 (decode_time_components, lisp_seconds_argument): New functions.
11485 (make_time): Now static.
11486 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11487 Report an error if the time is invalid, rather than having the caller
11490 * fileio.c: Include <stat-time.h>
11491 (Fcopy_file): Copy higher-resolution time stamps.
11492 Prefer to set the time stamp via a file descriptor if that works.
11493 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11494 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11495 (Fvisited_file_modtime, Fset_visited_file_modtime):
11496 Support higher-resolution time stamps.
11498 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11500 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11502 * image.c (prepare_image_for_display, clear_image_cache)
11503 (lookup_image): Port to higer-resolution time stamps.
11505 * keyboard.c (start_polling, bind_polling_period):
11506 Check for time stamp overflow.
11507 (read_char, kbd_buffer_get_event, timer_start_idle)
11508 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11509 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11510 Port to higher-resolution time stamps. Do not assume time_t is signed.
11511 (decode_timer): New function. Timers are now vectors of length 9,
11512 not 8, to accommodate the picosecond component.
11513 (timer_check_2): Use it.
11515 * nsterm.m (select_timeout, timeval_subtract): Remove.
11516 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11517 as they're a bit more accurate and handle overflow better.
11518 (ns_select): Change prototype to be compatible with pselect.
11519 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11520 * nsterm.h (ns_select): Adjust prototype.
11522 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11523 us-resolution time stamps.
11524 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11526 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11528 * lisp.h (time_overflow): New decl.
11529 (wait_reading_process_output): First arg is now intmax_t, not int,
11530 to accommodate larger waits.
11532 * process.h (struct Lisp_Process.read_output_delay):
11533 Now counts nanoseconds, not microseconds.
11534 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11536 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11537 (wait_reading_process_output):
11538 Port to ns-resolution time stamps.
11539 (Faccept_process_output, wait_reading_process_output):
11540 Check for time stamp overflow. Do not assume time_t is signed.
11541 (select_wrapper): Remove; we now use pselect.
11542 (Fprocess_attributes): Now generates ns-resolution time stamps.
11544 * sysdep.c: Include utimens.h. Don't include utime.h
11545 or worry about struct utimbuf; gnulib does that for us now.
11546 (gettimeofday): Remove; gnulib provides a substitute.
11547 (make_timeval): New function.
11548 (set_file_times): Now sets ns-resolution time stamps.
11549 New arg FD; all uses changed.
11550 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11551 (system_process_attributes):
11552 Now returns ns-resolution time stamp. All uses changed.
11553 Check for time stamp overflow.
11555 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11556 provides a substitute now.
11558 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11559 since it guarantees struct timespec.
11560 (EMACS_TIME): Now struct timespec, so that we can support
11561 ns-resolution time stamps.
11562 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11563 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11564 (EMACS_USECS): Remove.
11565 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11566 so multiply the arg by 1000 before storing it.
11567 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11569 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11570 Port to ns-resolution time stamps.
11571 (EMACS_TIME_NEG_P): Remove; replaced by....
11572 (EMACS_TIME_SIGN): New macro.

11574 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
11575 (set_file_times, make_time, lisp_time_argument): Adjust signature.
11576 (make_timeval, make_lisp_time, decode_time_components): New decls.
11577 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11578 that it mishandled time_t overflow. You can't compare by subtracting!
11579 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11580 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11582 * term.c: Include <sys/time.h>.
11583 (timeval_to_Time): New function, for proper overflow wraparound.
11584 (term_mouse_position, term_mouse_click): Use it.
11586 * undo.c (record_first_change): Support higher-resolution time stamps
11587 in the undo buffer.
11588 (Fprimitive_undo): Use them when restoring time stamps.
11590 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11591 (w32_get_internal_run_time):
11592 Port to higher-resolution Emacs time stamps.
11593 (ltime): Now accepts single 64-bit integer, as that's more convenient
11596 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11598 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11599 for compatibility with pselect. Support ns-resolution time stamps.
11601 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11603 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11604 Check for time stamp overflow, and support ns-resolution time stamps.
11606 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11607 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11608 (timeval_subtract): Remove; no longer needed.
11609 (XTflash, XTring_bell, x_wait_for_event):
11610 Port to ns-resolution time stamps. Don't assume time_t is signed.
11612 2012-06-22 Chong Yidong <cyd@gnu.org>

11616 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11618 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11619 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11620 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11621 staticidx goes up to 1597 out of 1600 = 0x640.)
11623 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11625 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
11626 Otherwise, the umask might be mistakenly 0 while handling input signals.
11628 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
11630 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

11637 access to `contents' member of Lisp_Vector objects with AREF and ASET
11640 2012-06-19 Chong Yidong <cyd@gnu.org>
11642 * frame.c (delete_frame): When selecting a frame on a different
11643 text terminal, do not alter the terminal's top-frame.
11645 * xdisp.c (format_mode_line_unwind_data): Record the target
11646 frame's selected window and its terminal's top-frame.
11647 (unwind_format_mode_line): Restore them.
11648 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11650 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11651 since tty frames can be explicitly named.
11652 (prepare_menu_bars): Likewise.
11654 * term.c (Ftty_top_frame): New function.
11656 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

11659 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11660 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11661 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11662 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
11663 (METER_1, METER_2): Simplify.
11665 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
11667 * data.c (Fdefalias): Return `symbol' (bug#11686).
11669 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11671 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11672 gets killed during executing of this function (Bug#11665).
11673 Try to always return Qt when the buffer has been actually killed.
11674 (Vkill_buffer_query_functions): In doc-string say that functions
11675 run by this hook should not change the current buffer.
11677 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11679 Fix recently-introduced process.c problems found by static checking.
11680 * process.c (write_queue_push, write_queue_pop, send_process):
11681 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
11682 (write_queue_pop): Fix pointer signedness problem.
11683 (send_process): Remove unused local.
11685 2012-06-17 Chong Yidong <cyd@gnu.org>
11687 * xdisp.c (redisplay_internal): No need to redisplay terminal
11688 frames that are not on top.

11697 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
11699 * lisp.h (eassert): Assume C89 or later.
11700 This removes the need for CHECK.
11701 (CHECK): Remove. Its comments about always evaluating its
11702 argument were confusing, as 'eassert' typically does not evaluate
11705 * coding.c (produce_chars): Use ptrdiff_t, not int.
11707 * xterm.c (x_draw_underwave): Check for integer overflow.
11708 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
11710 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
11712 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
11713 referenced (Bug#11583).

12042 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12043 would mishandle a string argument "Xc" if X was a multibyte

12098 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12099 Convert pctcpu and pctmem to Lisp float properly.

12104 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

12126 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12127 Use 'float' consistently, rather than 'float' in most places
12128 and 'double' in a couple of places.
12130 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12132 * xdisp.c (handle_stop): Detect whether we have overlay strings
12133 loaded by testing it->current.overlay_string_index to be
12134 non-negative, instead of checking whether n_overlay_strings is
12135 positive. (Bug#11587)

12152 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12153 for the duration of call to load_charset, to avoid problems with

12158 decrement the inhibition flag, instead of just setting or

12163 Remove obsolete '#define static' cruft.
12164 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

12174 Clean up __executable_start, monstartup when --enable-profiling.
12175 The following changes affect the code only when profiling.
12176 * dispnew.c (__executable_start): Rename from safe_bcopy.
12177 Define only on platforms that need it.
12178 * emacs.c: Include <sys/gmon.h> when profiling.
12179 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
12180 (__executable_start): Remove decl, since lisp.h does it now.
12181 (safe_bcopy): Remove decl; no longer has that name.
12182 (main): Coalesce #if into single bit of code, for simplicity.
12183 Cast pointers to uintptr_t, since standard libraries want integers
12185 * lisp.h (__executable_start): New decl.
12187 2012-05-31 Glenn Morris <rgm@gnu.org>
12189 * image.c (Fimagemagick_types): Doc fix.
12191 2012-05-30 Jim Meyering <meyering@redhat.com>
12193 * callproc.c (Fcall_process_region): Include directory component

12196 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
12198 * alloc.c, lisp.h (make_pure_vector): Now static.
12200 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
12202 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
12203 Move to byte-run.el.
12204 (Fautoload): Do the hash-doc more carefully.
12205 * data.c (Fdefalias): Purify definition, except for keymaps.
12206 (Qdefun): Move from eval.c.
12207 * lisp.h (Qdefun): Remove.
12208 * lread.c (read1): Tiny simplification.
12210 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
12212 Do not create empty overlays with the evaporate property (Bug#9642).
12213 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12214 Bug#9642, but explicitly check that the buffer the overlay would
12215 be moved to is live and rearrange lines to make sure that errors
12216 will not put the overlay in an inconsistent state.
12217 (Fdelete_overlay): Cosmetics.
12219 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12221 * w32term.c (my_bring_window_to_top): New function.
12222 (x_raise_frame): Use handle returned by DeferWindowPos, which
12223 could be different from the original one.
12224 Call my_bring_window_to_top instead of my_set_foreground_window.
12227 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
12228 by calling BringWindowToTop.

12233 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12235 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12236 This avoids undefined behavior that might cause the eassert
12237 to not catch an out-of-range value.
12239 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12241 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
12242 Update dependencies.
12244 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12246 * bidi.c (bidi_mirror_char): Fix last change.
12248 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

12251 when referring to sectname field in printf format.
12253 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
12255 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12256 Only r_alloc_inhibit_buffer_relocation needed to be added;
12257 the others were already declared.
12259 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12260 before checking whether it's out of range. Put the check inside
12262 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12264 2012-05-27 Ken Brown <kbrown@cornell.edu>
12266 * callproc.c (Fcall_process): Restore a line that was accidentally
12267 commented out in the 2011-02-13 change (bug#11547).
12269 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12271 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12272 defined on ralloc.c.
12274 * buffer.c [REL_ALLOC]: Remove prototypes of
12275 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12276 they are now on lisp.h.
12278 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12280 * search.c (search_buffer): Use it to inhibit relocation of buffer
12281 text while re_search_2 is doing its job, because re_search_2 is
12282 passed C pointers to buffer text. (Bug#11519)
12284 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12285 Update value to 24.
12287 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12288 state after an additional call to move_it_in_display_line_to, keep
12289 the values of it->max_ascent and it->max_descent found for the
12291 (pos_visible_p): Revert the comparison against bottom_y to what it
12292 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12295 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12297 Fix coding-related core dumps with gcc -ftrapv.
12298 The code was computing A - B, where A and B are pointers, and B is
12299 random garbage. This can lead to core dumps on platforms that
12300 have special pointer registers, and it also leads to core dumps on
12301 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12302 A - B only when B is initialized properly.
12303 * coding.c (coding_set_source, coding_set_destination): Return void.
12304 (coding_change_source, coding_change_destinations): New functions,
12305 with the old behaviors of coding_set_source and coding_set_destination.
12306 All callers that need an offset changed to use these new functions.
12308 2012-05-26 Glenn Morris <rgm@gnu.org>
12310 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
12312 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12314 Extend mouse support on W32 text-mode console.
12315 * xdisp.c (draw_row_with_mouse_face):
12316 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12318 * w32console.c: Include window.h.
12319 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12321 (initialize_w32_display): Initialize mouse-highlight data.
12323 * w32inevt.c: Include termchar.h and window.h.
12324 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12325 moves, call note_mouse_highlight. If help_echo changed, call
12326 gen_help_event to produce help-echo message in the echo area.
12327 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12330 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12332 * lread.c (read1): Simplify slightly to avoid an overflow warning
12333 with GCC 4.7.0 on x86-64.
12335 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12337 * bidi.c (bidi_mirror_char): Revert last change: an int is
12338 definitely wide enough here.
12340 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12342 Fix integer width and related bugs (Bug#9874).
12343 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
12344 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
12345 (string_bytes, check_sblock, allocate_string_data):
12346 (compact_small_strings, Fmake_bool_vector, make_string)
12347 (make_unibyte_string, make_multibyte_string)
12348 (make_string_from_bytes, make_specified_string)
12349 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
12350 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
12352 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12353 (allocate_pseudovector):
12354 Use int, not EMACS_INT, where int is wide enough.
12355 (inhibit_garbage_collection, Fgarbage_collect):
12356 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12357 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12358 int might not be wide enough.
12359 (bidi_cache_search, bidi_cache_find, bidi_init_it)
12360 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
12361 (bidi_at_paragraph_end, bidi_find_paragraph_start)
12362 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
12363 (bidi_level_of_next_char, bidi_move_to_visually_next):
12364 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12365 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
12366 (Fkill_buffer, Fset_buffer_major_mode)
12367 (advance_to_char_boundary, Fbuffer_swap_text)
12368 (Fset_buffer_multibyte, overlays_at, overlays_in)
12369 (overlay_touches_p, struct sortvec, record_overlay_string)
12370 (overlay_strings, recenter_overlay_lists)
12371 (adjust_overlays_for_insert, adjust_overlays_for_delete)
12372 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
12373 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
12374 (Foverlay_recenter, last_overlay_modification_hooks_used)
12375 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
12376 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12377 (validate_region): Omit unnecessary test for b <= e,
12378 since that's guaranteed by the previous test.
12379 (adjust_overlays_for_delete): Avoid pos + length overflow.
12380 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12381 (report_overlay_modification):
12382 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12383 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12384 Omit pointer cast, which isn't needed anyway, and doesn't work
12385 after the EMACS_INT -> ptrdiff_t change.
12386 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12387 * buffer.h: Adjust decls to match defn changes elsewhere.
12388 (struct buffer_text, struct buffer):
12389 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12390 Use EMACS_INT, not int, where int might not be wide enough.
12391 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12392 not int, to avoid needless 32-bit limit on 64-bit hosts.
12393 (exec_byte_code): Use tighter memory-full test, one that checks
12394 for alloca overflow. Don't compute the address of the object just
12395 before an array, as that's not portable. Use EMACS_INT, not
12396 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12397 * callint.c (Fcall_interactively):
12398 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12399 * callproc.c (call_process_kill, Fcall_process):
12400 Don't assume pid_t fits into an Emacs fixnum.
12401 (call_process_cleanup, Fcall_process, child_setup):
12402 Don't assume pid_t fits into int.
12403 (call_process_cleanup, Fcall_process, delete_temp_file)

12405 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12406 (Fcall_process): Simplify handling of volatile integers.

12408 * casefiddle.c (casify_object, casify_region, operate_on_word)
12409 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
12410 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12411 (casify_object): Avoid integer overflow when overallocating buffer.
12412 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12413 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12414 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12415 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12416 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
12417 integers are now checked earlier. All uses replaced with XINT.
12419 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12420 For CCL_MapSingle, check that content and value are in int range.
12421 (ccl_driver, Fregister_code_conversion_map):
12422 Check that Vcode_version_map_vector is a vector.
12423 (resolve_symbol_ccl_program): Check that vector header is in range.
12424 Always copy the vector, so that we can check its contents reliably
12425 now rather than having to recheck each instruction as it's being
12426 executed. Check that vector words fit in 'int'.
12427 (ccl_get_compiled_code, Fregister_ccl_program)
12428 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12429 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12430 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12431 contents are in range.
12432 (Fccl_execute_on_string): Check that status is in range.
12433 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12434 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12435 Accept and return EMACS_INT, not int, because callers can pass values
12436 out of 'int' range.
12437 (c_string_width, strwidth, lisp_string_width, chars_in_text)
12438 (multibyte_chars_in_text, parse_str_as_multibyte)

12441 (string_escape_byte8, Fget_byte):
12442 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12443 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12444 avoid mishandling large integers.
12445 * character.h: Adjust decls to match defn changes elsewhere.
12446 * charset.c (load_charset_map_from_file, find_charsets_in_text)
12447 (Ffind_charset_region):
12448 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

12451 Don't assume fixnum fits in int.
12452 (load_charset_map_from_vector, Fmap_charset_chars):
12453 Remove now-unnecessary CHECK_NATNUMs.
12454 (Fdefine_charset_internal): Check ranges here, more carefully.
12455 Don't rely on undefined behavior with signed left shift overflow.
12456 Don't assume unsigned int fits into fixnum, or that fixnum fits
12457 into unsigned int. Don't require max_code to be a valid fixnum;
12458 that's not true for gb10830 4-byte on a 32-bit host. Allow
12459 invalid_code to be a cons, for the same reason. Require code_offset
12460 to be a character. Avoid int overflow if max_char is close
12462 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12463 this is intended anyway and avoids some undefined behavior.
12464 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12465 INDEX_TO_CODE_POINT, as that's what it expects.
12466 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12467 * charset.h (DECODE_CHAR): Return int, not unsigned;
12468 this is what was intended anyway, and it avoids undefined behavior.
12469 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12470 integer-overflow issues.
12471 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12472 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12473 where the argument is EMACS_INT, and this behavior is not intended.
12474 * chartab.c (Fmake_char_table, Fset_char_table_range)
12475 (uniprop_get_decoder, uniprop_get_encoder):
12476 Don't assume fixnum fits in int.
12477 * cmds.c (move_point): New function, that does the gist of
12478 Fforward_char and Fbackward_char, but does so while checking
12479 for integer overflow more accurately.
12480 (Fforward_char, Fbackward_char): Use it.
12481 (Fforward_line, Fend_of_line, internal_self_insert)
12482 (internal_self_insert):
12483 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12484 Fix a FIXME, by checking for integer overflow when calculating
12485 target_clm and actual_clm.

12517 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12518 (consume_chars): Rewrite to not calculate an address outside buffer.
12519 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
12520 Don't access memory outside of the args array.
12521 (Fdefine_coding_system_internal): Check for charset-id overflow.
12522 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
12523 result of ENCODE_CHAR.
12524 * coding.h: Adjust decls to match defn changes elsewhere.
12525 (struct coding_system):
12526 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12540 (struct composition):
12541 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12542 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
12543 Do not attempt to compute the address of the object just before a
12544 buffer; this is not portable.
12546 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12547 (Faset): Use int, not EMACS_INT, where int is wide enough.
12548 (Fstring_to_number): Don't assume fixnums fit in int.

13243 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
13245 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
13246 reference to image_cache->refcount.
13247 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
13249 2012-05-17 Juri Linkov <juri@jurta.org>
13251 * search.c (Fword_search_regexp, Fword_search_backward)
13252 (Fword_search_forward, Fword_search_backward_lax)
13253 (Fword_search_forward_lax): Move functions to isearch.el
13254 (bug#10145, bug#11381).
13256 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13258 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13260 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13262 * lread.c (init_obarray): Declare Qt and Qnil as special.
13264 2012-05-14 Glenn Morris <rgm@gnu.org>
13266 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13267 Put "libexec" before "bin", for the sake of init_callproc_1.
13269 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13271 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13273 * unexaix.c: Port to more-recent AIX compilers.
13274 (report_error, report_error_1, make_hdr, copy_sym)
13275 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13276 Make arguments const char *, not char *, to avoid violations of C
13277 standard and to fix some AIX warnings reported by Gilles Pion.
13279 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13281 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13282 already have overlays loaded.
13283 (handle_single_display_spec): Before returning without displaying
13284 fringe bitmap, synchronize the bidi iterator with the main display
13285 iterator, by calling iterate_out_of_display_property.
13286 (iterate_out_of_display_property): Detect buffer iteration by
13287 testing that it->string is a Lisp string.
13288 (get_next_display_element): When the current object is exhausted,
13289 and there's something on it->stack, call set_iterator_to_next to
13290 proceed with what's on the stack, instead of returning zero.
13291 (set_iterator_to_next): If called at the end of a Lisp string,
13292 proceed to consider_string_end without incrementing string
13293 position. Don't increment display vector index past the end of
13294 the display vector. (Bug#11417)
13295 (pos_visible_p): Don't report a position visible when move_it_to
13296 stopped at the last line of window, which happens to be scanned
13297 backwards by the bidi iteration. (Bug#11464)
13299 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13301 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13302 and right-margin display specs even if the spec is invalid or we
13303 are on a TTY, and thus unable to display on the fringes.
13304 That's because the text with the property will not be displayed anyway,
13305 so we need to signal to the caller that this is a "replacing"
13306 display spec. This fixes display when the spec is invalid or we
13309 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13311 * unexaix.c (make_hdr): Fix typo in prototype.
13312 This bug broke the build on AIX. Problem reported by Gilles Pion.
13314 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13316 * keyboard.c (kbd_buffer_get_event): Read special events also in
13317 batch mode. (Bug#11415)
13319 2012-05-12 Glenn Morris <rgm@gnu.org>
13321 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13323 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13325 * lisp.mk (lisp): Add newcomment.elc.
13327 2012-05-12 Glenn Morris <rgm@gnu.org>
13329 * Makefile.in (MKDIR_P): New, set by configure.
13330 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13332 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13334 Remove unused function hourglass_started.
13335 * dispextern.h (hourglass_started):
13336 * w32fns.c (hourglass_started):
13337 * xdisp.c (hourglass_started): Remove.
13339 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13341 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13342 Update dependencies.
13344 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13346 * xgselect.c (xg_select): Put maxfds+1 into a var.
13347 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13349 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13351 2012-05-10 Dave Abrahams <dave@boostpro.com>
13353 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13354 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13356 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13358 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13359 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13360 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13361 Initialize xd_registered_buses.
13363 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13365 Untag more efficiently if USE_LSB_TAG.
13366 This is based on a proposal by YAMAMOTO Mitsuharu in
13367 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13368 For an admittedly artificial (nth 8000 longlist) benchmark on
13369 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13370 Emacs's overall text size by 1%.
13371 * lisp.h (XUNTAG): New macro.
13372 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13373 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13374 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13375 * eval.c (Fautoload):
13376 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13377 * frame.h (XFRAME): Use XUNTAG.
13379 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13380 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13381 Remove unportable assumptions about print widths of types like
13383 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13384 intptr_t when converting between pointer and integer, to avoid GCC
13385 warnings about wrong width.
13387 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13389 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13390 stack for each reader_thread, instead of defaulting to 8MB
13391 determined by the linker. This avoids failures in creating
13392 subprocesses on Windows 7, see the discussion in this thread:
13393 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13395 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13397 Fix up display of the *Minibuf-0* buffer in the mini window.
13398 * keyboard.c (read_char): Don't clear the echo area if there's no
13400 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13401 contents of *Minibuf-0*) if there's no message displayed in its stead.
13403 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13405 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13408 2012-05-06 Chong Yidong <cyd@gnu.org>
13410 * lisp.mk (lisp): Update.
13412 2012-05-05 Jim Meyering <meyering@redhat.com>
13414 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13416 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13418 * data.c (PUT_ERROR): New macro.
13419 (syms_of_data): Use it. Add new error type `user-error'.
13420 * undo.c (user_error): New function.
13421 (Fprimitive_undo): Use it.
13422 * print.c (print_error_message): Adjust print style for `user-error'.
13423 * keyboard.c (user_error): New function.
13424 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13426 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13428 Do not limit current-time-string to years 1000..9999.
13429 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13430 (Fcurrent_time_string): Support any year that is supported by the
13431 underlying localtime representation. Don't use asctime, as it
13432 has undefined behavior for years outside the range -999..9999.
13434 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13436 Fix race conditions involving setenv, gmtime, localtime, asctime.
13437 Without this fix, interrupts could mess up code that uses these
13438 nonreentrant functions, since setting TZ invalidates existing
13439 tm_zone or tzname values, and since most of these functions return
13440 pointers to static storage.
13441 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13442 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13443 Grow the critical sections to include not just invoking
13444 localtime/gmtime, but also accessing these functions' results
13445 including their tm_zone values if any, and any related TZ setting.
13446 (format_time_string): Last arg is now struct tm *, not struct tm **,
13447 so that the struct tm is saved in the critical section.
13448 All callers changed. Simplify allocation of initial buffer, partly
13449 motivated by the fact that memory allocation needs to be outside
13450 the critical section.
13452 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13454 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13455 with RESET_INTERVAL.
13457 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13458 Remove duplicated buffer name initialization.
13460 2012-05-02 Jim Meyering <jim@meyering.net>
13462 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13464 * xfns.c (x_window): Use xstrdup (Bug#11375).
13466 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13468 * xdisp.c (pos_visible_p): If already at a newline from the
13469 display string before the 'while' loop, don't walk back the glyphs
13470 from it3.glyph_row. Solves assertion violation when the display
13471 string begins with a newline (egg.el). (Bug#11367)
13473 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13475 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13478 2012-05-01 Glenn Morris <rgm@gnu.org>
13480 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13481 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13482 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13483 All were removed before 23.1.
13485 * dispnew.c: Remove HAVE_LIBNCURSES test;
13486 it is always true on relevant platforms.
13488 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13489 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13491 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13493 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13495 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13496 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13499 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13501 Do not avoid creating empty evaporating overlays (Bug#9642).
13502 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13503 That is, do not delete an evaporating overlay if it becomes
13504 empty after its bounds are adjusted to fit within its buffer.
13505 This fix caused other problems, and I'm reverting it until we get
13506 to the bottom of them.
13508 2012-04-27 Chong Yidong <cyd@gnu.org>
13510 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13512 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13514 * xdisp.c (pos_visible_p): If the window start position is beyond
13515 ZV, start the display from buffer beginning. Prevents assertion
13516 violation in init_iterator when the minibuffer window is scrolled
13517 via the scroll bar.
13519 * window.c (window_scroll_pixel_based): Likewise.
13521 2012-04-27 Chong Yidong <cyd@gnu.org>
13523 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13525 2012-04-27 Glenn Morris <rgm@gnu.org>
13527 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13528 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13530 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13532 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13533 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13535 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13537 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13538 display element, check also the underlying string or buffer
13539 character. (Bug#11341)
13541 * w32menu.c: Include w32heap.h.
13542 (add_menu_item): If the call to AppendMenuW (via
13543 unicode_append_menu) fails, disable Unicode menus only if we are
13544 running on Windows 9X/Me.
13546 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13548 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13549 (xgetint): Add missing shift for LSB tags.
13551 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13553 * keyboard.c (read_char): Don't wipe echo area for select window
13554 events: These might get delayed via `mouse-autoselect-window'
13557 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13559 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13560 manipulation of :loaded-from data.
13562 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13564 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13565 now a cons (bug#11311).
13567 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13569 Do not create empty overlays with the evaporate property (Bug#9642).
13570 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13571 if it becomes empty after its bounds are adjusted to fit within
13572 its buffer. Without this fix, in a nonempty buffer (let ((o
13573 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13574 yields an empty overlay that has the evaporate property, which is
13575 not supposed to happen.
13577 Fix minor GTK3 problems found by static checking.
13578 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13579 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13580 (struct _EmacsFixedClass, emacs_fixed_get_type):
13581 Move decls here from emacsgtkfixed.h, since they needn't be public.
13582 (emacs_fixed_get_type): Now static.
13583 (emacs_fixed_class_init): Omit unused local.
13584 (emacs_fixed_child_type): Remove; unused.
13585 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13586 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13587 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13588 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
13589 (EMACS_FIXED_GET_CLASS): Remove; unused.
13590 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
13592 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
13593 Problem reported by Juanma Barranquero for Windows -Wunused-function.
13595 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13597 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13598 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13599 (__malloc_size_t, __malloc_ptrdiff_t):
13600 Remove. All uses removed, replaced by the definiens if needed,
13601 since we can assume C89 or better now.
13602 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

13610 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13611 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13612 Define using prototypes, not old style.
13613 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
13614 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
13615 (align): Don't assume that signed integer overflow wraps around.
13616 Omit unused local var.
13617 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
13618 (_free_internal_nolock, memalign, mallochook, reallochook):
13619 Omit no-longer-needed casts.
13620 (valloc): Use getpagesize, not __getpagesize.
13621 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
13622 (struct hdr): The 'magic' member is now size_t, not unsigned long.
13624 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
13626 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
13628 Move functions from C to Lisp. Make non-blocking method calls
13629 the default. Implement further D-Bus standard interfaces.
13631 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

13647 (xd_signature, xd_append_arg): Allow float for integer types.
13648 (xd_get_connection_references): New function.
13649 (xd_get_connection_address): Rename from xd_initialize.
13650 Return cached address.
13651 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
13652 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp

13655 Return number of refcounts.
13656 (Fdbus_get_unique_name): Make stronger parameter check.

13690 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13692 * sysdep.c [__FreeBSD__]: Minor cleanups.
13693 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13694 Use Emacs indenting style more consistently. Avoid some casts.
13695 Use 'double' consistently rather than mixing 'float' and 'double'.

13713 * print.c (print_preprocess): Only check print_depth if print-circle
13715 (print_object): Check for cycles even when print-circle is nil and
13716 print-gensym is t, but only check print_depth if print-circle is nil.

13720 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13721 set the status to "failed" and ensure that sentinel is run.
13723 2012-04-20 Glenn Morris <rgm@gnu.org>
13725 * process.c (Fset_process_inherit_coding_system_flag)
13726 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

13736 farther than the first row after the header line, if any.
13737 Don't consider the header-line row as "partially visible", even if
13738 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
13740 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

13754 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
13755 -Wunused-result, -Wunused-variable. This should go away once
13756 the Emacs and Gnulib regex code is merged.
13757 (xmalloc, xrealloc): Now static.
13759 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

13776 New extern decls, to avoid calling undeclared functions.
13777 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13778 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13779 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13780 (NEED_MEM_INSERT): New macro.
13781 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13782 Remove one incorrect comment and fix another.

13797 Remove decls. This fixes an "It stinks!".
13799 * alloc.c (which_symbols): Fix alignment issue / type clash.
13801 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13803 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
13804 (struct Lisp_Misc_Any): Likewise.
13805 (struct Lisp_Free): Likewise.

13817 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
13818 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13819 * s/netbsd.h, s/sol2-6.h:
13820 Remove definition of GC_MARK_STACK, since the default now works.
13821 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

13823 no longer the default.
13824 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13826 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

13847 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
13849 2012-04-11 Daniel Colascione <dancol@dancol.org>
13851 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13852 against is gone. It's better to use vfork now so that when Cygwin
13853 gains a new, working vfork, we use it automatically (bug#10398).
13855 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
13857 * window.c (save_window_save): Obey window-point-insertion-type.

13875 * w32.c (w32_delayed_load): Record the full path of the library
13876 being loaded (bug#10424).
13878 2012-04-09 Glenn Morris <rgm@gnu.org>
13880 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13881 not just in the obarray, before snarfing them. (Bug#11036)

13898 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13899 attempts per process (connection).
13901 2012-04-09 Chong Yidong <cyd@gnu.org>
13903 * eval.c (Fuser_variable_p, user_variable_p_eh)

13908 * minibuf.c (Fread_variable): Callers changed.
13910 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13912 * xdisp.c (set_cursor_from_row): If the display string appears in
13913 the buffer at position that is closer to point than the position
13914 after the display string, display the cursor on the first glyph of
13915 the display string. Fixes cursor display when a 'display' text
13916 property immediately follows invisible text. (Bug#11094)
13918 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13920 composite.c: use 'double' consistently
13921 * composite.c (get_composition_id): Use 'double' consistently
13922 instead of converting 'float' to 'double' and vice versa; this is
13923 easier to understand and avoids a GCC warning.
13925 2012-04-09 Glenn Morris <rgm@gnu.org>
13927 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13928 preparation for dumping it with emacs. (Bug#4789)

13950 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13951 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13952 objects, as mark_maybe_pointer will catch them otherwise.

13971 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13972 [!WINDOWSNT]: New macros.
13973 (init_libxml2_functions, libxml2_loaded_p): New functions.
13974 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13975 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13976 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13977 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13979 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13980 Call init_libxml2_functions before calling libxml2 functions.
13981 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13983 * emacs.c: Don't include libxml/parser.h.

13989 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13991 * indent.c (Fvertical_motion): If there is a display string at
13992 point, use it.vpos to compute how many lines to backtrack after
13993 move_it_to point. (Bug#11133)
13995 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13997 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13998 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13999 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14000 macros related to unification of CJK characters. For the details,
14001 see the discussion following the message here:
14002 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14004 2012-04-04 Chong Yidong <cyd@gnu.org>

14018 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14020 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14021 position we get to after a call to move_it_to fails the
14022 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14023 only if we wind up in a string from display property. (Bug#11063)
14025 * window.c (Fdelete_other_windows_internal): Invalidate the row
14026 and column information about mouse highlight, so that redisplay
14027 restores it after reallocating the glyph matrices. (Bug#7464)
14029 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14030 string comes from a `display' text property, use the buffer
14031 position of that property as if we actually saw that position in
14033 (move_it_by_lines): Remove the assertion that
14034 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14035 violated when there's a before-string at the beginning of a line.
14038 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14040 * xdisp.c (append_space_for_newline): If the default face was

14043 extending the face to the end of the line.
14044 (display_line): Call extend_face_to_end_of_line when the default
14045 face was remapped. (Bug#11068)

14067 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14068 (command_loop_1): Use it; inhibit selection update for

14073 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14075 2012-03-25 Kenichi Handa <handa@m17n.org>
14077 * dispextern.h (struct glyph): Change the bit length of
14078 glyphless.ch to 22 to make the member glyphless fit in 32 bits.

14093 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14095 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14096 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14097 when fetching a multibyte character consumes more bytes than
14098 CHAR_BYTES returns, due to unification of CJK characters in
14099 string_char. (Bug#11073)
14101 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14103 * process.c (wait_reading_process_output): Handle pty disconnect
14104 by refraining from sending oneself a SIGCHLD (bug#10933).
14106 2012-03-22 Chong Yidong <cyd@gnu.org>
14108 * dispextern.h (struct it): New member string_from_prefix_prop_p.

14135 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14137 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14138 that is not from display property, accept the row as a "cursor
14139 row" if one of the string's character has a non-nil `cursor'
14140 property. Fixes cursor positioning when there are newlines in
14141 overlay strings, e.g. in icomplete.el. (Bug#11035)
14143 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

14174 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14177 2012-03-03 Glenn Morris <rgm@gnu.org>
14179 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14181 2012-03-02 Eli Zaretskii <eliz@gnu.org>

14184 position past the first glyph_row that ends at ZV. (Bug#10902)
14185 (redisplay_window, next_element_from_string): Fix typos in
14187 (redisplay_window): Pass to move_it_vertically the margin in
14188 pixels, not in screen lines.
14190 2012-03-02 Glenn Morris <rgm@gnu.org>
14192 * buffer.c (buffer-list-update-hook): Doc fix.
14194 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14196 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14197 push_it before setting up the iterator for the first overlay
14198 string, even if we have an empty string loaded.
14199 (next_overlay_string): If there's an empty string on the iterator
14200 stack, pop the stack. (Bug#10903)
14202 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14204 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14205 Suggested by Stefan Monnier in
14206 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14207 * alloc.c (widen_to_Lisp_Object): New static function.
14208 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14209 and widening them to Lisp_Objects. This would work even if
14210 USE_LSB_TAG is defined and wide integers are used, which might
14211 happen in a future version of Emacs.
14213 2012-02-25 Chong Yidong <cyd@gnu.org>
14215 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

14220 before saving to clipboard manager.
14222 2012-02-24 Chong Yidong <cyd@gnu.org>
14224 * keyboard.c (process_special_events): Handle all X selection
14225 requests in kbd_buffer, not just the next one (Bug#8869).
14227 2012-02-23 Chong Yidong <cyd@gnu.org>
14229 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14230 call when setting menu-bar-lines and tool-bar-lines parameters.
14231 (unwind_create_frame_1): New helper function.
14233 * window.c (inhibit_window_configuration_change_hook): New var.
14234 (run_window_configuration_change_hook): Obey it.

14244 * fileio.c (Vfile_name_handler_alist): Doc fix.
14246 * buffer.c (Fget_file_buffer): Protect against invalid file
14247 handler return value.

14252 when computing $valmask.
14254 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14255 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14256 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14257 It's useless in that case, and it can cause problems on hosts
14258 that allocate halves of EMACS_INT values separately.
14259 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14260 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14261 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14262 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14263 it avoids undefined behavior on hosts where shifting right by more
14264 than the word width has undefined behavior.
14266 2012-02-19 Chong Yidong <cyd@gnu.org>
14268 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14269 (Funhandled_file_name_directory, Ffile_name_as_directory)
14270 (Fdirectory_file_name, Fexpand_file_name)
14271 (Fsubstitute_in_file_name): Protect against invalid file handler
14272 return values (Bug#10845).
14274 2012-02-18 Eli Zaretskii <eliz@gnu.org>

14286 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14288 2012-02-15 Chong Yidong <cyd@gnu.org>
14290 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14291 marked as special. Also, starting docstrings with * is obsolete.

14306 2012-02-12 Chong Yidong <cyd@gnu.org>
14308 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14309 as that creates a dangerous corner case.
14311 * window.c (Fdelete_window_internal): Invalidate the mouse
14312 highlight (Bug#9904).
14314 2012-02-12 Glenn Morris <rgm@gnu.org>

14319 * nsselect.m (Fx_own_selection_internal)
14320 (Fx_disown_selection_internal, Fx_selection_exists_p)
14321 (Fx_selection_owner_p, Fx_get_selection_internal):
14322 Sync docs and argument specs with the xselect.c versions.
14324 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

14344 2012-02-07 Chong Yidong <cyd@gnu.org>
14346 * buffer.c (Fbuffer_local_variables)
14347 (buffer_lisp_local_variables): Handle unbound vars correctly;
14348 don't let Qunbound leak into Lisp.
14350 2012-02-07 Glenn Morris <rgm@gnu.org>
14352 * image.c (Fimagemagick_types): Doc fix.
14354 * image.c (imagemagick-render-type): Change it from a lisp object
14355 to an integer. Move the doc here from the lisp manual.

14372 2012-02-04 Eli Zaretskii <eliz@gnu.org>
14374 * w32.c (get_emacs_configuration_options):
14375 Include --enable-checking, if specified, in the return value.
14377 2012-02-04 Martin Rudalics <rudalics@gmx.at>
14379 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
14380 after rounding frame sizes. (Bug#9723)

14385 before BEGV. (Bug#10696)
14387 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
14389 Handle overflow when computing char display width (Bug#9496).
14390 * character.c (char_width): Return EMACS_INT, not int.
14391 (char_width, c_string_width): Check for overflow when
14392 computing the width; this is possible now that individual
14393 characters can have unbounded width. Problem introduced
14394 by merge from Emacs 23 on 2012-01-19.

14418 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
14420 (x_produce_glyphs): If the component of a composition is a null

14425 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
14426 first 2 arguments are identical. This makes inserting large
14427 output from a subprocess an order of magnitude faster on
14428 MS-Windows, where all sbrk'ed memory is always contiguous.
14430 2012-01-31 Glenn Morris <rgm@gnu.org>

14527 * xdisp.c (rows_from_pos_range): Accept additional argument
14528 DISP_STRING, and accept any glyph in a row whose object is that
14529 string as eligible for mouse highlight. Fixes mouse highlight of
14530 display strings from overlays. (Bug#10464)
14532 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
14534 emacs: fix an auto-save permissions race condition (Bug#10400)

14536 (Fmake_directory_internal): Use it.
14537 (do_auto_save_make_dir): Set it, instead of invoking chmod after

15047 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15048 is set, removing the need for VIRT_ADDRESS_VARIES.
15049 (PURE_P): Use a more-efficient implementation that needs just one

15052 to 4 (xorl, subq, cmpq, setbe).
15053 * alloc.c (pure): Always extern now, since that's the

15064 (erase_phys_cursor, update_window_cursor, show_mouse_face)
15065 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
15066 behave as if the cursor position were at the window margin.
15068 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15069 and the cursor position is out of bounds, behave as if the cursor
15070 position were at the window margin. (Bug#10075)
15072 2011-11-18 Chong Yidong <cyd@gnu.org>
15074 * window.c (Fwindow_combination_limit): Make first argument

15543 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15545 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
15546 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
15547 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
15548 (Fmove_to_window_line): Doc fix.
15550 2011-10-27 Chong Yidong <cyd@gnu.org>
15552 * process.c (make_process): Set gnutls_state to NULL.
15554 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15555 non-NULL, regardless of GNUTLS_INITSTAGE.
15556 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
15557 an error. Set process slots as soon as we allocate them.
15559 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
15561 2011-10-27 Chong Yidong <cyd@gnu.org>
15563 * gnutls.c (emacs_gnutls_deinit): New function.
15564 Deallocate credentials structures as well as calling gnutls_deinit.
15565 (Fgnutls_deinit, Fgnutls_boot): Use it.
15567 * process.c (make_process): Initialize GnuTLS credentials to NULL.
15568 (deactivate_process): Call emacs_gnutls_deinit.
15570 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15572 * image.c (x_create_x_image_and_pixmap):
15573 * w32.c (sys_rename, w32_delayed_load):
15574 * w32font.c (fill_in_logfont):
15575 * w32reg.c (x_get_string_resource): Silence compiler warnings.
15577 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
15579 * w32fns.c (w32_default_color_map): New function,
15580 extracted from Fw32_default_color_map.
15581 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
15583 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
15585 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
15587 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
15589 * keyboard.c (test_undefined): New function (bug#9751).
15590 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
15592 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
15594 * sysdep.c (init_sys_modes): Fix the check for the controlling
15595 terminal (Bug#6649).
15597 2011-10-20 Eli Zaretskii <eliz@gnu.org>
15599 * dispextern.h (struct bidi_it): New member next_en_type.
15601 * bidi.c (bidi_line_init): Initialize the next_en_type member.
15602 (bidi_resolve_explicit_1): When next_en_pos is valid for the
15603 current character, check also for next_en_type being WEAK_EN.
15604 (bidi_resolve_weak): Don't enter the expensive loop if the current
15605 position is before next_en_pos. Record the bidi type of the first
15606 non-ET, non-BN character we find, in addition to its position.
15607 (bidi_level_of_next_char): Invalidate next_en_type when
15608 next_en_pos is over-stepped.
15610 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15612 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15613 * editfns.c: Rewrite current-time-zone so that it invokes
15614 the equivalent of (format-time-string "%Z") to get the time zone name.
15615 This fixes a bug when the time zone name contains characters that
15616 need converting from the system time locale to Emacs internal format.
15617 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15618 that patch fixed format-time-string to do the conversion, but
15619 I forgot to fix current-time-zone.
15620 (format_time_string): New function, containing most of
15621 what Fformat_time_string used to contain.
15622 (Fformat_time_string): Rewrite in terms of format_time_string.
15623 This doesn't change this function's behavior.
15624 (current-time-zone): Rewrite to use format_time_string.
15625 This fixes the bug reported by Michael Schierl in
15626 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15627 Jason Rumney's 2007-06-07 change worked around this bug, but
15629 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15631 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15633 * xdisp.c (start_display): If the character at POS is displayed
15634 via a display vector, reset IT->current.dpvec_index to zero.
15635 (try_window_reusing_current_matrix): If a line ends in a display
15636 vector or the next line starts in a display vector, continue
15637 redrawing the window even though the character position of
15638 start_row was reached.
15641 2011-10-18 Chong Yidong <cyd@gnu.org>
15643 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15644 with nobreak-char-display too.
15646 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15648 Fix part 3 of bug#9771.
15649 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15650 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15651 non-neutral characters if the current character is a paragraph
15652 separator (a.k.a. Newline). This avoids running the same
15653 expensive loop twice, once when we consume the preceding newline
15654 and the other time when the line actually needs to be displayed.
15655 Avoid the loop when we see neutrals on the base embedding level
15656 following a character whose directionality is the same as the
15657 paragraph's. This avoids running the expensive loop when a line
15658 ends in a long sequence of neutrals, like control characters.
15659 Add assertion against STRONG_AL type. Slightly rearrange code
15660 that determines the type of a neutral given the first non-neutral
15662 (bidi_level_of_next_char): Set next_en_pos to zero when
15663 invalidating its info.
15665 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15667 * xdisp.c (push_display_prop): Determine whether to record string
15668 or buffer position by IT->string, not by IT->method. Allow
15669 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15670 (move_it_vertically_backward): Don't look for character position
15671 immediately after the newline when in a continuation line.
15674 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15676 * window.c (coordinates_in_window): Rewrite and delabelize
15677 vertical border check. (Bug#5357) (Bug#9618)
15679 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15681 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15682 errors in XSetWindowBorder (bug#9310).
15684 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15686 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15687 avoid crash when xmalloc overrun checking is enabled.
15689 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15691 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15692 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15693 cursor motion with <left> and <right> arrow keys.
15695 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15696 some callers set that themselves.
15698 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15700 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15701 display string and the previous row comes from the same string and
15702 is empty. (Bug#9739) (Bug#9738)
15704 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15706 * doc.c (get_doc_string): Encode file name (bug#9735).
15708 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15710 * bidi.c (bidi_level_of_next_char):
15711 * xdisp.c (get_visually_first_element): Remove old incorrect
15712 comments regarding the Unicode Line Separator character.
15714 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15716 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15718 * alloc.c (Fgc_status): Do not access beyond zombies array
15719 boundary if nzombies > MAX_ZOMBIES.
15720 * alloc.c (dump_zombies): Add missing format specifier.
15722 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15724 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15725 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15727 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15728 Some packages use them to denote characters with modifiers.
15730 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15732 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15733 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15734 matching a pp-number. Rename parameter var to var1.
15736 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15738 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15740 2011-10-08 Glenn Morris <rgm@gnu.org>
15742 * callint.c (Fcall_interactively): Give a more explicit error for the
15743 'c' case with a non-character input. (Bug#8479)
15745 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15747 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15749 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15750 lines that are hscrolled on the left.
15752 * dispnew.c (buffer_posn_from_coords): Account for a possible
15753 presence of header-line. (Bug#4426)
15755 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15757 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15758 Don't advertise functionality which we discourage or doesn't work.
15760 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15762 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15763 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15764 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15765 this makes Emacs dump core during garbage collection on rare
15766 occasions. sizeof is obviously inferior to offsetof here, so
15767 stick with offsetof.
15768 (GC_POINTER_ALIGNMENT): New macro.
15769 (mark_memory): Omit 3rd (offset) arg; caller changed.
15770 Don't assume EMACS_INT alignment is the same as pointer alignment.
15772 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15774 * keyboard.c (read_key_sequence_remapped): New var.
15775 (read_key_sequence): Compute remapping in the right buffer.
15776 (command_loop_1): Use read_key_sequence's remapping directly.
15778 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15780 * dired.c (file_name_completion): Don't expand file name.
15781 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15782 before checking file name handler.
15784 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15785 they've been requested explicitly (bug#9591).
15787 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15789 * keymap.c (Fsingle_key_description): Use make_specified_string
15790 instead of build_string to build string from push_key_description.
15793 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15795 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15796 This fixes a Y2038 bug on 64-bit hosts.
15797 * buffer.c (reset_buffer):
15798 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15799 (Fclear_buffer_auto_save_failure):
15800 Use 0, not -1, to represent an unset failure time, since time_t
15801 might not be signed.
15803 Remove dependency on glibc malloc internals.
15804 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15805 Move back here from lisp.h, but with their new implementations.
15806 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15807 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15808 * charset.c (charset_table_init): New static var.
15809 (syms_of_charset): Use it instead of xmalloc. This removes a
15810 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15811 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15812 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15813 Move back to alloc.c.
15814 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15815 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15817 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15819 * nsterm.m (windowDidResize): Call x_set_window_size only when
15820 ns_in_resize is true. Otherwise set pixelwidth/height and
15821 call change_frame_size (Bug#9628).
15823 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15825 Port --enable-checking=all to Fedora 14 x86-64.
15826 * charset.c (syms_of_charset): Also account for glibc malloc's
15827 internal overhead when calculating the initial malloc maximum.
15829 Port --enable-checking=all to Fedora 14 x86.
15830 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15832 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15833 (overrun_check_realloc, overrun_check_free):
15834 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15835 That way, xmalloc returns a properly-aligned pointer even if
15836 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15837 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15838 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15839 into account when calculating the initial malloc maximum.
15840 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15841 Move here from alloc.c, so that charset.c can use it too.
15842 Properly align; the old code wasn't right for common 32-bit hosts
15843 when configured with --enable-checking=all.
15844 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15845 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15847 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15849 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15852 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15854 * xdisp.c (compute_display_string_end): If there's no display
15855 string at CHARPOS, return -1.
15857 * bidi.c (bidi_fetch_char): When compute_display_string_end
15858 returns a negative value, treat the character as a normal
15859 character not covered by a display string. (Bug#9624)
15861 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15863 * lread.c (Fread_from_string): Fix typo in docstring.
15865 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15867 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15868 newline, reseat the iterator instead of bidi-iterating there one
15869 character at a time. (Bug#9610)
15870 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15871 TO_CHARPOS if the bidi iterator is at base embedding level.
15873 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15875 * lread.c (readevalloop): Use correct code for NBSP.
15876 (read1): Likewise. (Bug#9608)
15878 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15880 * dbusbind.c (Fdbus_register_signal): When service is not
15881 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15883 2011-09-25 Glenn Morris <rgm@gnu.org>
15885 * buffer.c (truncate-lines): Doc fix.
15887 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15889 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15890 (Fset_window_next_buffers): Doc fix.
15892 2011-09-24 Glenn Morris <rgm@gnu.org>
15894 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15896 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15898 Fix minor problems found by static checking.
15899 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15900 * indent.c (Fvertical_motion): Fix == vs = typo.
15902 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15904 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15905 Default value is now t. Doc fix.
15907 * indent.c (Fvertical_motion): Compute and apply the overshoot
15908 logic when moving up, not only when moving down. Fix the
15909 confusing name and values of the it_overshoot_expected variable;
15910 logic changes accordingly. (Bug#9254) (Bug#9549)
15912 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15913 CHARPOS is covered by a display string which includes newlines.
15914 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15915 is covered by a display string with embedded newlines.
15917 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15919 * dbusbind.c (Fdbus_register_signal): Add match rule to
15920 Vdbus_registered_objects_table. (Bug#9581)
15921 (Fdbus_register_method, Vdbus_registered_objects_table):
15924 2011-09-24 Jim Meyering <meyering@redhat.com>
15926 do not ignore write error for any output size
15927 The previous change was incomplete.
15928 While it makes emacs --batch detect the vast majority of stdout
15929 write failures, errors were still ignored whenever the output size is
15930 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15931 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15932 && echo FAIL: ignored write error
15933 FAIL: ignored write error
15934 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15935 && echo FAIL: ignored write error
15936 FAIL: ignored write error
15937 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15939 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15941 * emacs.c (Fkill_emacs): In noninteractive mode exit
15942 non-successfully if a write error occurred on stdout. (Bug#9574)
15944 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15946 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15949 * dispextern.h (struct it): Update the comment documenting what
15952 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15954 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15955 a display string, extend search for cursor position to end of row.
15956 (find_row_edges): If the row ends in a newline from a display
15957 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15958 Handle the case of a display string with multiple newlines.
15959 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15960 non-empty line. Fixes confusing cursor motion with arrow keys at
15961 the beginning of a line that starts with whitespace.
15963 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15965 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15968 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15970 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15971 boolean (Bug#9154).
15973 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15975 * xdisp.c (display_line): Record maximum and minimum buffer
15976 positions even if no glyphs were produced (e.g., by a zero-width
15977 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15978 buffer positions that will be removed from the glyph row because
15980 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15981 column is beyond frame width: don't subtract 1 "pixel" when
15982 computing width of the stretch.
15983 (reseat_at_next_visible_line_start): Undo the change made on
15984 2011-09-17 that saved paragraph information and restored it after
15985 the call to `reseat'. (Bug#9545)
15987 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15989 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15990 and turn window cursor on if cleared (Bug#9415).
15992 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15994 * search.c (boyer_moore): Take unibyte characters from pattern
15995 literally. (Bug#9458)
15997 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15999 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16001 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16003 Fix minor problem found by static checking.
16004 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16005 initialized, to pacify gcc -Wuninitialized.
16007 * fileio.c: Report proper errno when syscall falls.
16008 (Finsert_file_contents): Save and restore errno,
16009 so that report_file_error outputs the correct diagnostic.
16010 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16012 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16014 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16016 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16018 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16019 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16021 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16023 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16024 about the current paragraph and restore it after the call to reseat.
16026 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16027 (bidi_find_paragraph_start): Search back for paragraph beginning
16028 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16029 (bidi_move_to_visually_next): Only trigger paragraph-related
16030 computations when the last character is a newline or at EOB, not
16031 just any NEUTRAL_B. (Bug#9470)
16033 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16034 truncated lines if point is covered by a display string. (Bug#9524)
16036 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16038 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16039 (cons_to_x_long): New function.
16040 (lisp_data_to_selection_data): Use it. Correct the test for
16041 short-versus-long data; it was negated. Break out of vector
16042 loop, for efficiency, when a long datum is discovered.
16044 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16046 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16048 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16050 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16051 GCC PR/17406) by declaring this function with external scope.
16053 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16055 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16056 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16058 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16060 * editfns.c (Fformat): Correctly handle text properties on "%%".
16062 2011-09-15 Eli Zaretskii <eliz@gnu.org>
16064 * xterm.c (x_draw_composite_glyph_string_foreground):
16065 * w32term.c (x_draw_composite_glyph_string_foreground):
16066 * term.c (encode_terminal_code):
16067 * composite.c (composition_update_it, get_composition_id):
16068 * xdisp.c (get_next_display_element)
16069 (fill_composite_glyph_string): Add comments about special meaning
16070 of TAB characters in a composition.
16072 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16074 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16075 This occurs when processing a multibyte format.
16076 Problem reported by Wolfgang Jenker.
16078 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16080 * xdisp.c (try_cursor_movement): Only check for exact match if
16081 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16083 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16085 Remove unused external symbols.
16086 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16087 * xdisp.c (calc_pixel_width_or_height): Now static.
16088 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16089 * indent.c (check_display_width):
16090 * w32term.c: Fix comment to match code.
16091 * xterm.c, xterm.h (x_catching_errors): Remove.
16093 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16095 * xselect.c: Use signed conversions more consistently (Bug#9498).
16096 (selection_data_to_lisp_data): Assume incoming selection data are
16097 signed integers, not unsigned. This is to be consistent with
16098 outgoing selection data, which was modified to use signed integers
16099 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16100 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16101 expects long, not unsigned long.
16103 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16105 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16106 computation of loop end. Reported by Johan Bockgård
16109 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16111 * frame.c (Fother_visible_frames_p): Function deleted.
16113 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16115 * indent.c (compute_motion): Process display vector front to back
16116 rather than the other way around. (Bug#2496)
16118 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16120 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16122 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16124 * minibuf.c (Fread_from_minibuffer): Doc fix.
16126 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16128 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16129 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16131 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16133 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16134 value for non-existent files.
16136 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16138 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16139 set its "size" to -1. This will set the modtime_size field of
16140 the corresponding buffer to -1, which is what
16141 verify-visited-file-modtime expects for files that do not exist.
16144 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16146 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16148 * lisp.h: ... from here. push_key_description is no longer
16149 defined in keyboard.c, so its declaration should not be in
16150 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16151 logically belongs with push_key_description.
16153 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16155 * buffer.h: Include <sys/types.h> instead of <time.h>.
16156 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16157 Problem reported by Herbert J. Skuhra.
16159 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16161 * xml.c (parse_region): Make the parsing work for
16162 non-comment-starting XML files again (bug#9144).
16164 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16166 * image.c (gif_load): Fix calculation of bottom and right corner.
16169 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16171 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16172 redisplay in small windows.
16174 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16176 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16178 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16180 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16181 Operate on live windows only.
16183 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16185 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16187 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16189 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16190 only under bidi iteration.
16192 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16194 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16196 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16198 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16199 Without this fix, the command to link temacs failed due to an
16200 undefined symbol __builtin_isnan. This is because
16201 /usr/include/iso/math_c99.h #defines isnan(x) to
16202 __builtin_isnan(x), but the bundled gcc, which identifies itself
16203 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16205 * floatfns.c (isnan): #undef, and then #define to a clone of
16207 (Fisnan): Always define, since it's always available now.
16208 (syms_of_floatfns): Always define isnan at the Lisp level.
16210 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16212 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16214 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16216 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16217 The previous code assumed that file offsets (off_t values) fit in
16218 EMACS_INT variables, which is not true on typical 32-bit hosts.
16219 The code messed up by falsely reporting buffer overflow in cases
16220 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16221 when "big" contains more than 2**29 bytes, even though this
16222 inserts just one byte and does not overflow the buffer.
16223 (Finsert_file_contents): Store file offsets as off_t
16224 values, not as EMACS_INT values. Check for overflow when
16225 converting between EMACS_INT and off_t. When checking for
16226 buffer overflow or for overlap, take the offsets into account.
16227 Don't use EMACS_INT for small values where int suffices.
16228 When checking for overlap, fix a typo: ZV was used where
16229 ZV_BYTE was intended.
16230 (Fwrite_region): Don't assume off_t fits into 'long'.
16231 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16233 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16235 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16237 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16239 sprintf-related integer and memory overflow issues (Bug#9412).
16241 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16242 (esprintf, exprintf, evxprintf): New functions.
16243 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16244 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16245 (modify_event_symbol): Do not assume that the length of
16246 name_alist_or_stem is safe to alloca and fits in int.
16247 (Fexecute_extended_command): Likewise for function name and binding.
16248 (Frecursion_depth): Wrap around reliably on integer overflow.
16249 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16250 since some callers pass EMACS_INT values.
16251 (Fsingle_key_description): Don't crash if symbol name contains more
16252 than MAX_ALLOCA bytes.
16253 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16254 (get_minibuffer): Arg is now EMACS_INT, not int.
16255 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16256 (esprintf, exprintf, evxprintf): New decls.
16257 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16259 * dbusbind.c (signature_cat): New function.
16260 (xd_signature, Fdbus_register_signal):
16261 Do not overrun buffer; instead, report string overflow.
16263 * dispnew.c (add_window_display_history): Don't overrun buffer.
16264 Truncate instead; this is OK since it's just a log.
16266 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16267 even if the time zone offset is outlandishly large.
16268 Don't mishandle offset == INT_MIN.
16270 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16271 when creating daemon; the previous buffer-overflow check was incorrect.
16273 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16274 which has the guts of the old verror function.
16276 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16277 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16279 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16280 (font_unparse_xlfd): Don't blindly alloca long strings.
16281 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16282 fits in int, when using sprintf. Use single snprintf to count
16283 length of string rather than counting it via multiple sprintfs;
16284 that's simpler and more reliable.
16285 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16286 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16287 sprintf, in case result does not fit in int.
16289 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16290 (fontset_from_font): Print it.
16292 * frame.c (tty_frame_count): Now printmax_t, not int.
16293 (make_terminal_frame, set_term_frame_name): Print it.
16294 (x_report_frame_params): In X, window IDs are unsigned long,
16295 not signed long, so print them as unsigned.
16296 (validate_x_resource_name): Check for implausibly long names,
16297 and don't assume name length fits in 'int'.
16298 (x_get_resource_string): Don't blindly alloca invocation name;
16299 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16302 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16303 (xg_check_special_colors, xg_set_geometry):
16304 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16306 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16307 Use esprintf, not sprintf, in case result does not fit in int.
16309 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16310 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16311 it as a large positive number.
16312 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16313 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16315 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16316 in case result does not fit in int.
16318 * print.c (float_to_string): Detect width overflow more reliably.
16319 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16320 buffer overrun. Don't assume list length fits in 'int'. Treat
16321 print length of 0 as 0, not as infinity; to be consistent with other
16322 uses of print length in this function. Don't overflow print length
16323 index. Don't assume hash table size fits in 'long', or that
16324 vectorlike size fits in 'unsigned long'.
16326 * process.c (make_process): Use printmax_t, not int, to format
16327 process-name gensyms.
16329 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16331 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16332 to avoid potential buffer overrun.
16334 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16335 if X resource line is longer than 512 bytes.
16337 * xfns.c (x_window): Make sprintf buffer a bit bigger
16338 to avoid potential buffer overrun.
16340 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16342 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16344 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16346 Integer overflow fixes for scrolling, etc.
16347 Without these, Emacs silently mishandles large integers sometimes.
16348 For example, "C-u 4294967297 M-x recenter" was treated as if
16349 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16351 * xdisp.c (try_window_id): Check Emacs fixnum range before
16352 converting to 'int'.
16354 * window.c (window_scroll_line_based, Frecenter):
16355 Check that an Emacs fixnum is in range before assigning it to 'int'.
16356 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16357 values converted from Emacs fixnums.
16358 (Frecenter): Don't wrap around a line count if it is out of 'int'
16359 range; instead, treat it as an extreme value.
16360 (Fset_window_configuration, compare_window_configurations):
16361 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16363 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16364 that can exceed INT_MAX. Check that EMACS_INT value is in range
16365 before assigning it to the (possibly-narrower) index.
16366 (match_limit): Don't assume that a fixnum can fit in 'int'.
16368 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16371 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16372 (Fvertical_motion): Don't wrap around LINES values that don't fit
16373 in 'int'. Instead, treat them as extreme values. This is good
16374 enough for windows, which can't have more than INT_MAX lines anyway.
16376 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16378 * Require libxml/parser.h to avoid compilation warning.
16380 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16382 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16383 since this reportedly can destroy thread storage.
16385 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16387 * syntax.c (find_defun_start): Update all cache variables if
16388 exiting early (Bug#9401).
16390 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16392 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16394 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16395 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16396 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16398 * term.c (tty_append_glyph): New function.
16399 (produce_stretch_glyph): Static function and its prototype deleted.
16401 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16404 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16406 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16407 when checking :margin (Bug#9390).
16408 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16409 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16410 so that the name doesn't mislead. All uses changed.
16412 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16414 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16417 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16419 * xdisp.c (move_it_to): Don't bail out early when reaching
16420 position beyond to_charpos, if we are scanning backwards.
16421 (move_it_vertically_backward): When DY == 0, make sure we get to
16422 the first character in the line after the newline.
16424 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16426 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16427 (ccl_driver): Do not generate an out-of-range pointer.
16428 (Fccl_execute_on_string): Remove unnecessary check for
16429 integer overflow, noted by Stefan Monnier in
16430 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16431 Remove a FIXME that didn't need fixing.
16432 Simplify the newly-introduced buffer reallocation code.
16434 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16436 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16438 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16440 Integer and memory overflow issues (Bug#9196).
16442 * doc.c (get_doc_string): Rework so that
16443 get_doc_string_buffer_size is the actual buffer size, rather than
16444 being 1 less than the actual buffer size; this makes xpalloc more
16447 * image.c (x_allocate_bitmap_record, cache_image):
16448 * xselect.c (Fx_register_dnd_atom):
16449 Simplify previous changes by using xpalloc.
16451 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,

16456 (charset_compare): Don't overflow if priorities differ greatly.
16457 (Fsort_charsets): Don't assume list length fits in int.
16458 Check for size-calculation overflow when allocating sort data.
16459 (syms_of_charset): Allocate an initial charset table that is
16460 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16462 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16464 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16465 The actual value is always <= INT_MAX, and leaving it unsigned made

16468 * dispextern.h (struct glyph_matrix.rows_allocated)
16469 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16470 with xpalloc. The values are still always <= INT_MAX.

16480 (revalidate_region_cache, know_region_cache, region_cache_forward)
16481 (region_cache_backward, pp_cache):
16482 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16483 so that ptrdiff_t * can be passed to xpalloc.
16484 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16485 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

16500 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16502 Don't update size of array until after memory allocation succeeds,
16503 because xmalloc/xrealloc may not return.
16504 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16505 now that we have proper integer overflow checking.
16506 (record_overlay_string, overlay_strings): Catch overflows when
16507 calculating size of overlay_str_buf.
16509 * callproc.c (Fcall_process): Check for size overflow when
16510 calculating size of args2.
16511 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16512 Normally we prefer signed values, but sticking with ptrdiff_t would
16513 require adding more-complicated checks.
16515 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16516 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16517 Redo buffer-overflow calculations to avoid integer overflow.
16518 Add a FIXME comment where memory seems to be over-allocated.
16520 * character.c (Fstring): Check for size-calculation overflow.
16522 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid

16555 Don't assume message length fits in int.
16556 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16558 * emacs.c (main): Do not reallocate argv, since there is a null at
16559 the end that can be overwritten, and this way there's no need to
16560 worry about size-calculation overflow.
16561 (sort_args): Check for size-calculation overflow.
16563 * eval.c (init_eval_once, grow_specpdl): Don't update size until

16569 Check for integer overflow.
16570 (x_set_alpha): Do not assume XINT fits in int.
16572 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16573 This is for the members text_lines, text_cols, total_lines, total_cols,
16574 where the system imposes an 'int' limit.
16576 * fringe.c (Fdefine_fringe_bitmap):
16577 Don't update size until alloc works.

16582 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16583 Check for size-calculation overflow.
16584 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16585 do, as we prefer signed integers.

16591 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16592 * gtkutil.h: Change prototypes to match the above.
16594 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

16641 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16642 for command line length. Do not attempt to address one before the
16643 beginning of an array, as that's not portable.

16678 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16679 sizes, since they can exceed INT_MAX in size. Check for size

16684 Don't update size until alloc done.
16686 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16687 as sprintf is limited to int lengths.
16689 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16690 (X_LONG_MIN): New macros.
16691 Use them to make the following changes clearer.
16692 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16693 This change doesn't affect the value now, but it may help remind
16694 future maintainers not to raise the value too much later.
16695 (SELECTION_QUANTUM): Remove, replacing with ...
16696 (selection_quantum): ... new function, which avoids overflow.
16698 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16699 assumption that selection length fits in 'int'.

16716 Don't store size until memory allocation succeeds.
16717 (x_get_window_property): Plug memory leak on memory exhaustion.
16718 Don't double-block input; malloc is safe here. Don't assume 2**34
16719 - 4 fits in unsigned long. Add an xassert to check
16720 XGetWindowProperty overflow. Be more careful about overflow
16721 calculations, and distinguish size from memory overflow better.
16722 (receive_incremental_selection): When tracing, don't assume
16723 unsigned int is less than INT_MAX.
16724 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16725 harmful) conversions of unsigned short to int.
16726 (lisp_data_to_selection_data): Don't assume that integers
16727 in the range -65535 through -1 fit in an X unsigned short.
16728 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16729 result parameters unless successful. Rely on cons_to_unsigned
16730 to report problems with elements; the old code wasn't right anyway.
16731 (x_check_property_data): Check for int overflow; we cannot use
16732 a wider type due to X limits.

16765 * lisp.h (hash_lookup, hash_put):
16766 * minibuf.c (Ftest_completion):
16767 Use ptrdiff_t for hash table indexes, not int (which is too
16768 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16769 32-bit --with-wide-int hosts).
16771 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16772 Add a FIXME comment about memory leaks.

16780 with outlandish widths.
16781 * character.h (sanitize_tab_width): Rename from sanitize_width,
16782 now that we have two such functions. All uses changed.

16803 exceed limits imposed by XClientMessageEvent, as well as the usual
16804 ptrdiff_t and size_t limits.
16806 * keyboard.c: Overflow, signedness and related fixes.
16807 (make_lispy_movement): Use same integer type in forward decl
16808 that is used in the definition.
16809 (read_key_sequence, keyremap_step):
16810 Change bufsize argument back to int, undoing my 2011-03-30 change.
16811 We prefer signed types, and int is wide enough here.
16812 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16813 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16814 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16815 length, not size_t. Use ptrdiff_t for index, not int.
16816 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16817 possibility of integer overflow.
16819 Overflow, signedness and related fixes for images.

16841 (lookup_image): Remove unnecessary tests.
16842 (xbm_image_p): Locals are now of int, not EMACS_INT,
16843 since parse_image_check makes sure they fit into int.
16844 (png_load, gif_load, svg_load_image):
16845 Prefer int to unsigned where either will do.
16846 (tiff_handler): New function, combining the cores of the
16847 old tiff_error_handler and tiff_warning_handler.
16848 This function is rewritten to use vsnprintf and thereby avoid
16849 stack buffer overflows. It uses only the features of vsnprintf
16850 that are common to both POSIX and native Microsoft.
16851 (tiff_error_handler, tiff_warning_handler): Use it.
16852 (tiff_load, gif_load, imagemagick_load_image):
16853 Don't assume :index value fits in 'int'.
16854 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16855 (imagemagick_load_image): Check that crop parameters fit into
16856 the integer types that MagickCropImage accepts. Don't assume
16857 Vimagemagick_render_type has a nonnegative value. Don't assume
16858 size_t fits in 'long'.
16859 (gs_load): Use printmax_t to print the widest integers possible.

16873 (handle_single_display_spec): If the display spec is of the form
16874 `(space ...)', and specifies display in the text area, return 2
16876 (try_cursor_movement): Check for the need to scroll more
16877 accurately, and prefer exact match for point under bidi.
16878 Don't advance `row' beyond the last row of the window.

16896 buffers, return left-to-right.
16897 (set_cursor_from_row): Consider candidate row a win if its glyph
16898 represents a newline and point is on that newline. Fixes cursor
16899 positioning on the newline at EOL of R2L text within L2R
16900 paragraph, and vice versa.
16901 (try_cursor_movement): Check continued rows, in addition to
16902 continuation rows. Fixes unwarranted scroll when point enters a
16903 continued line of R2L text within an L2R paragraph, or vice versa.

16931 * xdisp.c (redisplay_window): When computing centering_position,
16932 account for the height of the header line. (Bug#8874)
16934 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16935 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16936 candidate is selected by the mouse, and that candidate has a
16937 composed character under the mouse.
16939 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16940 coordinates reported by pos-visible-in-window-p for a composed
16941 character in column zero.
16943 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

16950 consider it a hit if to_charpos is anywhere in the range of the
16951 composed buffer positions.
16953 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16955 * image.c (gif_load): Don't assume that each subimage has the same
16956 dimensions as the base image. Handle disposal method that is
16957 "undefined" by the gif spec (Bug#9335).

16966 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
16967 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16968 from an Org mode buffer to a Speedbar frame.
16970 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16971 a composition, take its buffer position from IT->cmp_it.charpos.
16972 Fixes cursor positioning at the beginning of a line that begins
16973 with a composed character.
16975 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16977 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16978 character bidirectional type, use STRONG_L instead. Fixes crashes
16979 in a buffer produced by `describe-categories'.
16981 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16982 members before the level stack, so they would be saved and
16983 restored when copying iterator state. Fixes incorrect reordering
16984 around TABs covered by display properties.
16986 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
16988 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

17074 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17075 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17076 the event loop (Bug#7276).
17078 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

17102 (Fnetwork_interface_list): Allocate in increments of bytes instead
17103 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17104 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17106 (struct ifflag_def): notrailers is smart on OSX.
17107 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17108 Get hardware address with getifaddrs if available.

17112 * xdisp.c (iterate_out_of_display_property): xassert that
17113 IT->position is set to within IT->object's boundaries. Break from
17114 the loop as soon as EOB is reached; avoids infloops in redisplay

17116 Set IT->current to match the bidi iterator unconditionally.
17117 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17118 entry. Force push_it to save on the stack the current
17119 buffer/string position, to be restored by pop_it. Fix flags in
17120 the iterator structure wrt the object coming from a display
17121 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17122 properties. (Bug#9284)
17124 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17126 * fontset.c (fontset_get_font_group): Add proper type checks.

17165 longlines-mode. (Bug#9254)
17166 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17167 word-wrap under bidirectional display. (Bug#9224)
17169 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17170 is non-zero, even if the data buffer is NULL. Fixes a crash in
17171 vertical-motion with longlines-mode. (Bug#9254)
17173 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17175 * bidi.c <bidi_cache_total_alloc>: Now static.

17181 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17182 amount allocated this far in `bidi_cache_total_alloc'.
17183 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17184 non-zero, only free the data buffer without restoring the cache
17185 contents. All callers changed.
17187 * dispextern.h (bidi_unshelve_cache): Update prototype.
17189 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

17250 DISP_PROP_P, and pass it to compute_display_string_pos.
17251 Only handle text covered by a display string if DISP_PROP_P is returned
17252 non-zero. All callers of bidi_fetch_char changed.

17343 In other words, assume that every image size is allowed, on non-X

17346 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17348 * regex.c (re_iswctype): Convert return values to boolean.
17350 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17352 * xdisp.c (compute_display_string_pos): Don't use cached display
17353 string position if the buffer had its restriction changed.
17356 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17358 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17360 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17362 Integer signedness and overflow and related fixes. (Bug#9079)
17364 * bidi.c: Integer size and overflow fixes.
17365 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17366 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17367 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17368 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17369 (bidi_find_other_level_edge):
17370 Use ptrdiff_t instead of EMACS_INT where either will do.
17371 This works better on 32-bit hosts configured --with-wide-int.
17372 (bidi_cache_ensure_space): Check for size-calculation overflow.
17373 Use % rather than repeated addition, for better worst-case speed.
17374 Don't set bidi_cache_size until after xrealloc returns, because it
17376 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17377 (bidi_cache_ensure_space): Also check that the bidi cache size
17378 does not exceed that of the largest Lisp string or buffer. See Eli
17379 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17381 * alloc.c (__malloc_size_t): Remove.
17382 All uses replaced by size_t. See Andreas Schwab's note
17383 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17385 * image.c: Improve checking for integer overflow.
17386 (check_image_size): Assume that f is nonnull, since
17387 it is always nonnull in practice. This is one less thing to
17388 worry about when checking for integer overflow later.
17389 (x_check_image_size): New function, which checks for integer
17390 overflow issues inside X.
17391 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17392 This removes the need for a memory_full check.
17393 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17394 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17395 (xbm_read_bitmap_data): Change locals back to 'int', since
17396 their values must fit in 'int'.
17397 (xpm_load_image, png_load, tiff_load):
17398 Invoke x_create_x_image_and_pixmap earlier,
17399 to avoid much needless work if the image is too large.
17400 (tiff_load): Treat overly large images as if
17401 x_create_x_image_and_pixmap failed, not as malloc failures.
17402 (gs_load): Use x_check_image_size.
17404 * gtkutil.c: Omit integer casts.
17405 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17406 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17408 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17410 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17411 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17412 would wrongly return t on a 64-bit host.
17414 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17415 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17416 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17417 and therefore cause GCC to emit a bogus diagnostic in some cases.
17419 * image.c: Integer signedness and overflow and related fixes.
17420 This is not an exhaustive set of fixes, but it's time to
17421 record what I've got.
17422 (lookup_pixel_color, check_image_size): Remove redundant decls.
17423 (check_image_size): Don't assume that arbitrary EMACS_INT values
17424 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17425 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17426 (tiff_load, imagemagick_load_image):
17427 Check for overflow in size calculations.
17428 (x_create_x_image_and_pixmap): Remove unnecessary test for
17429 xmalloc returning NULL; that can't happen.
17430 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17431 (xpm_color_bucket): Use better integer hashing function.
17432 (xpm_cache_color): Don't possibly over-allocate memory.
17433 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17434 (gif_memory_source):
17435 Use ptrdiff_t, not int or size_t, to record sizes.
17436 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17437 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17438 either works, as we prefer signed integers.
17439 (tiff_read_from_memory, tiff_write_from_memory):
17440 Return tsize_t, not size_t, since that's what the TIFF API wants.
17441 (tiff_read_from_memory): Don't fail simply because the read would
17442 go past EOF; instead, return a short read.
17443 (tiff_load): Omit no-longer-needed casts.
17444 (Fimagemagick_types): Don't assume size fits into 'int'.
17446 Improve hashing quality when configured --with-wide-int.
17447 * fns.c (hash_string): New function, taken from sxhash_string.
17448 Do not discard information about ASCII character case; this
17449 discarding is no longer needed.
17450 (sxhash-string): Use it. Change sig to match it. Caller changed.
17451 * lisp.h: Declare it.
17452 * lread.c (hash_string): Remove, since we now use fns.c's version.
17453 The fns.c version returns a wider integer if --with-wide-int is
17454 specified, so this should help the quality of the hashing a bit.
17456 * emacs.c: Integer overflow minor fix.
17457 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17458 Define only if GNU_LINUX.
17459 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17461 * dispnew.c: Integer signedness and overflow fixes.
17462 Remove unnecessary forward decls, that were a maintenance hassle.
17463 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17465 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17466 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17467 (prepare_desired_row, line_draw_cost):
17468 Use int, not unsigned, where either works.
17469 (save_current_matrix, restore_current_matrix):
17470 Use ptrdiff_t, not size_t, where either works.
17471 (init_display): Check for overflow more accurately, and without
17472 relying on undefined behavior.
17474 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17475 Remove, replacing with the new symbols in lisp.h. All uses changed.
17476 * fileio.c (make_temp_name):
17477 * filelock.c (lock_file_1, lock_file):
17478 * xdisp.c (message_dolog):
17479 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17480 Use pMd etc. instead.
17481 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17482 replacing the pWIDE etc. symbols removed from editfns.c.
17484 * keyboard.h (num_input_events): Now uintmax_t.
17485 This is (very slightly) less likely to mess up due to wraparound.
17488 * buffer.c: Integer signedness fixes.
17489 (alloc_buffer_text, enlarge_buffer_text):
17490 Use ptrdiff_t rather than size_t when either will do, as we prefer
17493 * alloc.c: Integer signedness and overflow fixes.
17494 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17495 (__malloc_size_t): Default to size_t, not to int.
17496 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17497 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17498 Prefer ptrdiff_t to size_t when either would do, as we prefer
17500 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17501 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17502 Now const. Initialize with values that are in range even if char
17504 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17505 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17506 These functions do the right thing with sizes > 2**32.
17507 (check_depth): Now ptrdiff_t, not int.
17508 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17509 Adjust to new way of storing sizes. Check for size overflow bugs
17511 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17512 slightly wrong anyway, as it missed one instance of
17513 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17514 (refill_memory_reserve): Omit needless cast to size_t.
17515 (mark_object_loop_halt): Mark as externally visible.
17517 * xselect.c: Integer signedness and overflow fixes.
17518 (Fx_register_dnd_atom, x_handle_dnd_message):
17519 Use ptrdiff_t, not size_t, since we prefer signed.
17520 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17521 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17522 x_dnd_atoms_size and x_dnd_atoms_length.
17524 * doprnt.c: Prefer signed to unsigned when either works.
17526 * doprnt.c (doprnt):
17528 * xdisp.c (vmessage):
17529 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17530 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17531 prefer signed arithmetic to avoid comparison confusion.
17532 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17533 but is a bit tricky.
17535 Assume freestanding C89 headers, string.h, stdlib.h.
17536 * data.c, doprnt.c, floatfns.c, print.c:
17537 Include float.h unconditionally.
17538 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17539 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17540 * regex.c: Likewise for stddef.h, string.h.
17541 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17542 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17543 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17544 (STDC_HEADERS): Remove obsolete defines.
17545 * sysdep.c: Include limits.h unconditionally.
17547 Assume support for memcmp, memcpy, memmove, memset.
17548 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17549 * regex.c (memcmp, memcpy):
17550 Remove; we assume C89 now.
17552 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17553 (__malloc_safe_bcopy): Remove; no longer needed.
17555 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17556 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17557 well either way, and we prefer signed to unsigned.
17559 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17561 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17562 closes the connection while we're reading (bug#9182).
17564 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17566 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17567 are specified (Bug#9168).
17569 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17571 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17572 Found by GCC static checking and --with-wide-int on a 32-bit host.
17574 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17576 * xdisp.c (compute_display_string_pos): Fix logic of caching
17577 previous display string position. Initialize cached_prev_pos to
17578 -1. Fixes slow-down at the beginning of a buffer.
17580 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17582 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17583 for attrs[LFACE_FONTSET_INDEX].
17585 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17587 * xml.c (parse_region): Remove unused local
17588 that was recently introduced.
17590 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17592 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17593 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17595 * xdisp.c (move_it_in_display_line_to): Record the best matching
17596 position for TO_CHARPOS while scanning the line, and restore it on
17597 exit if none of the characters scanned was an exact match.
17598 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17599 when exact match is impossible due to invisible text, and the
17600 lines are truncated.
17602 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17604 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17607 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17609 Fix a significant slow-down of cursor motion with C-n, C-p,
17610 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17611 auto-repeat under bidi redisplay in fontified buffers.
17612 * xdisp.c (compute_stop_pos_backwards): New function.
17613 (next_element_from_buffer): Call compute_stop_pos_backwards to
17614 find a suitable prev_stop when we find ourselves before
17616 (reseat): Don't look for prev_stop, as that could mean a very long
17618 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17619 <cached_disp_overlay_modiff>: Cache for last found display string
17621 (compute_display_string_pos): Return the cached position if asked
17622 about the same buffer in the same area of character positions, and
17623 the buffer wasn't changed since the time the display string
17624 position was cached.
17626 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17628 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17629 is an integer, which is important for empty lines. (Bug#9149)
17631 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17633 * frame.c (Fmodify_frame_parameters): In tty case, update the
17634 default face if necessary (Bug#4238).
17636 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17638 * editfns.c (Fstring_to_char): No need to explain what a character
17639 is in the docstring (Bug#6576).
17641 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17643 * xml.c (parse_region): Make sure we always return a tree.
17645 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17647 * xml.c (parse_region): If a document contains only comments,
17650 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17652 * xml.c (make_dom): Return comments, too.
17654 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17657 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17658 and the surrounding thread.
17659 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17660 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17661 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17663 * s/openbsd.h (BROKEN_SIGIO): Define.
17664 * unexelf.c (unexec) [__OpenBSD__]:
17665 Don't update the .mdebug section of the Alpha COFF symbol table.
17667 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17669 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17672 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17674 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17675 This fixes some race conditions on the permissions of any newly
17678 * alloc.c (valid_pointer_p): Use pipe, not open.
17679 This fixes some permissions issues when debugging.
17681 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17682 If fchown fails to set both uid and gid, try to set just gid,
17683 as that is sometimes allowed. Adjust the file's mode to eliminate
17684 setuid or setgid bits that are inappropriate if fchown fails.
17686 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17688 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17689 to compare Lisp_Objects.
17690 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17691 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17692 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17694 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17696 * lread.c (read_integer): Unread even EOF character.
17697 (read1): Likewise. Properly record start position of symbol.
17699 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17700 symbol character follows.
17702 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17704 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17705 This works around a problem with the previous change to Fcopy_file.
17706 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17707 and without this change, GCC might complain about discarding
17708 fchown's return value.
17710 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17712 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17714 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17716 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17718 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17720 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17721 it's used from the C level.
17723 * process.c: Use the same condition for POLL_FOR_INPUT in both
17724 keyboard.c and process.c (bug#1858).
17726 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17728 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17729 (Fgnutls_boot): Use it.
17731 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17733 * doc.c (Fsubstitute_command_keys): Revert last change.
17735 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17737 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17738 quotes the next character, and doesn't affect other longer
17739 sequences (bug#8935).
17741 * lread.c (syms_of_lread): Clarify that is isn't only
17742 `eval-buffer' and `eval-defun' that's affected by
17743 `lexical-binding' (bug#8460).
17745 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17747 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17748 bidi redisplay when a line includes both an image and is truncated.
17750 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17752 Fix minor problems found by static checking.
17753 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17754 (elsz): Now a signed constant, not a size_t var. We prefer signed
17755 types to unsigned, to avoid integer comparison confusion. Without
17756 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17757 "cannot optimize loop, the loop counter may overflow", a symptom
17759 * indent.c (Fvertical_motion): Mark locals as initialized.
17760 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17762 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17764 * search.c (Fre_search_backward): Mention `case-fold-search' in
17765 all the re_search_* functions (bug#8138).
17767 * keyboard.c (Fopen_dribble_file): Document when the file is
17770 2011-07-14 Eli Zaretskii <eliz@gnu.org>
17772 * bidi.c (bidi_dump_cached_states): Fix format of displaying
17775 Support bidi reordering of display and overlay strings.
17776 * xdisp.c (compute_display_string_pos)
17777 (compute_display_string_end): Accept additional argument STRING.
17778 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
17779 (reseat_to_string): Initialize bidi_it->string.s and
17780 bidi_it->string.schars.
17781 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
17782 NULL (avoids a crash in bidi_paragraph_init).
17783 Initialize itb.string.lstring.
17784 (init_iterator): Call bidi_init_it only of a valid
17785 buffer position was specified. Initialize paragraph_embedding to
17787 (reseat_to_string): Initialize the bidi iterator.
17788 (display_string): If we need to ignore text properties of

18284 (clone_per_buffer_values): Don't assume that

18286 This isn't true in general, and it's particularly not true
18287 if Emacs is configured with --with-wide-int.
18288 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
18289 New macros, used in the buffer.c change.

18325 Random fixes. E.g., (random) never returned negative values.
18326 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18327 subseconds part to the entropy, as that's a bit more random.
18328 Prefer signed to unsigned, since the signedness doesn't matter and
18329 in general we prefer signed. When given a limit, use a
18330 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18331 latter isn't right if USE_2_TAGS_FOR_INTS.
18332 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18333 not 0..VALMASK. Don't discard "excess" bits that random () returns.
18335 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
18337 * textprop.c (text_property_stickiness):
18338 Obey Vtext_property_default_nonsticky.

18345 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18346 This is more efficient than Ffile_directory_p and avoids a minor race.
18348 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18350 * buffer.c (Foverlay_put): Say what the return value is
18353 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18354 is a directory before asking whether to use the file name
18356 (barf_or_query_if_file_exists): Make the "File is a directory"
18357 error be more correct.
18359 * fns.c (Frequire): Remove the mention of the .gz files, since
18360 that's installation-specific, but keep the mention of
18361 `get-load-suffixes'.

18365 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

18373 Qgnutls_bootprop_verify_error (which is no longer used).
18375 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18376 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18377 Also (re)move comments that are misplaced or no longer relevant.
18379 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
18381 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

18440 (syms_of_keymap): Defsubr make-composed-keymap.
18441 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

18478 * eval.c (struct backtrace): Simplify and port the data structure.
18479 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18480 signed bit field, as this assumption is not portable and it makes
18481 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18482 "char debug_on_exit : 1" as this is not portable either; instead,
18483 use the portable "unsigned int debug_on_exit : 1". Remove unused
18484 member evalargs. Remove obsolete comments about cc bombing out.
18486 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18665 Check for size-calculation overflow.
18666 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
18668 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
18670 * lread.c: Integer overflow fixes.
18671 (read_integer): Radix is now EMACS_INT, not int,
18672 to improve quality of diagnostics for out-of-range radices.
18673 Calculate buffer size correctly for out-of-range radices.
18674 (read1): Check for integer overflow in radices, and in
18675 read-circle numbers.
18676 (read_escape): Avoid int overflow.
18677 (Fload, openp, read_buffer_size, read1)
18678 (substitute_object_recurse, read_vector, read_list, map_obarray):
18679 Use ptrdiff_t, not int, for sizes.

18694 2011-06-22 Leo Liu <sdl.web@gmail.com>
18696 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
18697 Move to minibuffer.el.
18699 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18701 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18702 The following patches are for when GLYPH_DEBUG && !XASSERT.
18703 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18704 * dispnew.c (flush_stdout):
18705 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18706 Mark as externally visible.
18707 * dispnew.c (check_window_matrix_pointers): Now static.
18708 * dispnew.c (window_to_frame_vpos):
18709 * xfns.c (unwind_create_frame):
18710 * xterm.c (x_check_font): Remove unused local.
18711 * scroll.c (CHECK_BOUNDS):
18712 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18713 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18714 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18715 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18716 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18718 (debug_method_add): Use va_list and vsprintf rather than relying
18719 on undefined behavior with wrong number of arguments.
18720 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18721 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18722 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18723 since we're not interested in debugging glyphs with old libraries.
18724 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18725 GCC 4.6.0's static checking.
18727 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18729 Integer overflow and signedness fixes (Bug#8873).

18738 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
18739 (x_create_bitmap_from_xpm_data):
18740 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
18741 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
18743 * xfaces.c (load_pixmap):
18744 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
18745 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18746 (.bitmaps_last, struct x_output.icon_bitmap):
18747 Use ptrdiff_t, not int, for bitmap indexes.
18748 (x_allocate_bitmap_record): Check for size overflow.
18749 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18751 Use ptrdiff_t, not int, for overlay counts.
18752 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18753 * editfns.c (overlays_around, get_pos_property):
18754 * textprop.c (get_char_property_and_overlay):
18755 * xdisp.c (next_overlay_change, note_mouse_highlight):
18756 * xfaces.c (face_at_buffer_position):
18757 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18758 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18759 (Fnext_overlay_change, Fprevious_overlay_change)
18760 (mouse_face_overlay_overlaps, Foverlays_in):
18761 Use ptrdiff_t, not int, for sizes.
18762 (overlays_at, overlays_in): Check for size-calculation overflow.
18764 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18766 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18767 (x_session_initialize): Do not assume string length fits in int.
18769 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18770 This is unlikely, but can occur if DPI is outlandish.
18772 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18773 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18775 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18776 * xrdb.c (magic_file_p, search_magic_path):
18777 Omit last arg SUFFIX; it was always 0. All callers changed.
18778 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18780 * xfont.c (xfont_match): Avoid need for strlen.
18782 * xfns.c: Don't assume strlen fits in int.
18783 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18785 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18786 not unsigned long, as we prefer signed integers. All callers changed.
18787 Detect integer overflow in repeat count.
18788 (message_dolog): Don't assume print length fits in 39 bytes.
18789 (display_mode_element): Don't assume strlen fits in int.
18791 * termcap.c: Don't assume sizes fit in int and never overflow.
18792 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18793 (gobble_line): Check for size-calculation overflow.
18795 * minibuf.c (Fread_buffer):
18796 * lread.c (intern, intern_c_string):
18797 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18798 Don't assume string length fits in int.
18800 * keyboard.c (parse_tool_bar_item):
18801 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18803 * font.c: Don't assume string length fits in int.
18804 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18805 Use ptrdiff_t, not int.
18806 (font_intern_prop): Don't assume string length fits in int.
18807 Don't assume integer property fits in fixnum.
18808 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18810 * filelock.c: Fix some buffer overrun and integer overflow issues.
18811 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18812 Reformulate so as not to need the command string.
18813 Invoke gzip -cd rather than gunzip, as it's more portable.
18814 (lock_info_type, lock_file_1, lock_file):
18815 Don't assume pid_t and time_t fit in unsigned long.
18816 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18817 (current_lock_owner): Prefer signed type for sizes.
18818 Use memcpy, not strncpy, where memcpy is what is really wanted.
18819 Don't assume (via atoi) that time_t and pid_t fit in int.
18820 Check for time_t and/or pid_t out of range, e.g., via a network share.
18821 Don't alloca where an auto var works fine.
18823 * fileio.c: Fix some integer overflow issues.
18824 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18825 Don't assume string length fits in int.
18826 (directory_file_name): Don't assume string length fits in long.
18827 (make_temp_name): Don't assume pid fits in int, or that its print
18828 length is less than 20.
18830 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18832 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18834 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18836 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18837 We prefer signed integers, even for size calculations.
18839 * emacs.c: Don't assume string length fits in 'int'.
18840 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18841 (main): Don't invoke strlen when not needed.
18843 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18844 (XD_DEBUG_MESSAGE): Don't waste a byte.
18846 * callproc.c (getenv_internal_1, getenv_internal)
18847 (Fgetenv_internal):
18848 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18850 * lread.c (invalid_syntax): Omit length argument.
18851 All uses changed. This doesn't fix a bug, but it simplifies the
18852 code away from its former Hollerith-constant appearance, and it's
18853 one less 'int' to worry about when looking at integer-overflow issues.
18854 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18856 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18857 This didn't break anything, but it didn't help either.
18858 It's confusing to put a bogus integer in a place where the actual
18859 value does not matter.
18860 (LIST_END_P): Remove unused macro and its bogus comment.
18861 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18863 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18864 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18866 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18867 We prefer signed types, and the value cannot exceed the EMACS_INT
18868 range anyway (because otherwise the length would not be representable).
18869 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18870 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18871 This avoids a GCC warning when WIDE_EMACS_INT.
18873 * indent.c (sane_tab_width): New function.
18874 (current_column, scan_for_column, Findent_to, position_indentation)
18875 (compute_motion): Use it. This is just for clarity.
18876 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18878 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18880 * lisp.h (lint_assume): New macro.
18881 * composite.c (composition_gstring_put_cache):
18882 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18884 * editfns.c, insdel.c:
18885 Omit unnecessary forward decls, to simplify future changes.
18887 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18889 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18891 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18892 Use much-faster test for byte-length change.
18893 Don't assume string byte-length fits in 'int'.
18894 Check that character arg fits in 'int'.
18895 (mapcar1): Declare byte as byte, for clarity.
18897 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18899 * fns.c (concat): Catch string overflow earlier.
18900 Do not rely on integer wraparound.
18902 * dispextern.h (struct it.overlay_strings_charpos)
18903 (struct it.selective): Now EMACS_INT, not int.
18904 * xdisp.c (forward_to_next_line_start)
18905 (back_to_previous_visible_line_start)
18906 (reseat_at_next_visible_line_start, next_element_from_buffer):
18907 Don't arbitrarily truncate the value of 'selective' to int.
18909 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18911 * composite.c: Don't truncate sizes to 'int'.
18912 (composition_gstring_p, composition_reseat_it)
18913 (composition_adjust_point): Use EMACS_INT, not int.
18914 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18915 not EMACS_UINT, for indexes.
18917 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18919 * buffer.c: Include <verify.h>.
18920 (struct sortvec.priority, struct sortstr.priority):
18921 Now EMACS_INT, not int.
18922 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18923 (struct sortstr.size, record_overlay_string)
18924 (struct sortstrlist.size, struct sortlist.used):
18925 Don't truncate size to int.
18926 (record_overlay_string): Check for size-calculation overflow.
18927 (init_buffer_once): Check at compile-time, not run-time.
18929 2011-06-22 Jim Meyering <meyering@redhat.com>
18931 Don't leak an XBM-image-sized buffer
18932 * image.c (xbm_load): Free the image buffer after using it.
18934 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18937 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18938 that Sun C diagnosed.
18939 * fns.c (secure_hash): Fix pointer signedness issue.
18940 * intervals.c (static_offset_intervals): New function.
18941 (offset_intervals): Use it.
18943 2011-06-21 Leo Liu <sdl.web@gmail.com>
18946 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18949 * fns.c (secure_hash): Rename from crypto_hash_function and change
18950 the first arg to accept symbols.
18951 (Fsecure_hash): New primitive.
18952 (syms_of_fns): New symbols.
18954 2011-06-20 Deniz Dogan <deniz@dogan.se>
18956 * process.c (Fset_process_buffer): Clarify return value in
18959 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18961 * dispnew.c (add_window_display_history): Use BVAR.
18963 * xdisp.c (debug_method_add): Use BVAR.
18964 (check_window_end, dump_glyph_matrix, dump_glyph)
18965 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18967 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18970 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18971 check till after the cache is created in init_frame_faces.
18973 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18975 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18977 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18979 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18980 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18981 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18983 Improve buffer-overflow checking (Bug#8873).
18984 * fileio.c (Finsert_file_contents):
18985 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18986 Remove the old (too-loose) buffer overflow checks.
18987 They weren't needed, since make_gap checks for buffer overflow.
18988 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18989 The old code merely checked for Emacs fixnum overflow, and relied
18990 on undefined (wraparound) behavior. The new code avoids undefined
18991 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18993 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18994 Tune. Don't use wider integers than needed. Don't use alloca.
18995 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18997 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18999 * insdel.c, lisp.h (buffer_overflow): New function.
19000 (insert_from_buffer_1, replace_range, replace_range_2):
19001 * insdel.c (make_gap_larger):
19002 * editfns.c (Finsert_char):
19003 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19005 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19007 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19009 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19011 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19012 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19014 * fileio.c: Don't assume EMACS_INT fits in off_t.
19015 (emacs_lseek): New static function.
19016 (Finsert_file_contents, Fwrite_region): Use it.
19017 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19019 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19021 * fns.c: Don't overflow int when computing a list length.
19022 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19023 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19024 truncation on 64-bit hosts. Check for QUIT every
19025 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19026 faster and is responsive enough.
19027 (Flength): Report an error instead of overflowing an integer.
19028 (Fsafe_length): Return a float if the value is not representable
19029 as a fixnum. This shouldn't happen except in contrived situations.
19030 (Fnthcdr, Fsort): Don't assume list length fits in int.
19031 (Fcopy_sequence): Don't assume vector length fits in int.
19033 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19034 (header_size, word_size): New constants.
19035 (allocate_vectorlike): Don't check size overflow here.
19036 (allocate_vector): Check it here instead, since this is the only
19037 caller of allocate_vectorlike that could cause overflow.
19038 Check that the new vector's length is representable as a fixnum.
19040 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19041 The previous code was bogus. For example, next_almost_prime (32)
19042 returned 39, which is undesirable as it is a multiple of 3; and
19043 next_almost_prime (24) returned 25, which is a multiple of 5 so
19044 why was the code bothering to check for multiples of 7?
19046 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19048 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19050 Variadic C functions now count arguments with ptrdiff_t.
19051 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19052 Back then I didn't know that the Emacs coding style prefers signed int.
19053 Also, in the meantime I found a few more instances where arguments
19054 were being counted with int, which may truncate counts on 64-bit
19055 machines, or EMACS_INT, which may be unnecessarily wide.
19056 * lisp.h (struct Lisp_Subr.function.aMANY)
19057 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19058 Arg counts are now ptrdiff_t, not size_t.
19059 All variadic functions and their callers changed accordingly.
19060 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19061 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19062 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19063 * callint.c (Fcall_interactively): Check arg count for overflow,
19064 to avoid potential buffer overrun. Use signed char, not 'int',
19065 for 'varies' array, so that we needn't bother to check its size
19066 calculation for overflow.
19067 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19068 * eval.c (apply_lambda):
19069 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19070 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19071 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19073 * callint.c (Fcall_interactively): Don't use index var as event count.
19075 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19076 * mem-limits.h (SIZE): Remove; no longer used.
19078 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19080 Remove unnecessary casts.
19081 * xterm.c (x_term_init):
19082 * xfns.c (x_set_border_pixel):
19083 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19084 These aren't needed now that we assume ANSI C.
19086 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19087 It's more likely to cause problems (due to unsigned overflow)
19090 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19092 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19094 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19096 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19098 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19100 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19102 GLYPH_CODE_FACE returns EMACS_INT, not int.
19103 * dispextern.h (merge_faces):
19104 * xfaces.c (merge_faces):
19105 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19106 Don't assume EMACS_INT fits in int.
19108 * character.h (CHAR_VALID_P): Remove unused parameter.
19109 * fontset.c, lisp.h, xdisp.c: All uses changed.
19111 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19113 * fns.c (concat): Minor tuning based on overflow analysis.
19114 This doesn't fix any bugs. Use int to hold character, instead
19115 of constantly refetching from Emacs object. Use XFASTINT, not
19116 XINT, for value known to be a character. Don't bother comparing
19117 a single byte to 0400, as it's always less.
19119 * floatfns.c (Fexpt):
19120 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19122 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19125 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19127 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19128 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19129 incorrectly succeed when S was a string, because 4294967386 was
19130 truncated before it was used.
19132 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19133 Otherwise, an out-of-range integer could cause undefined behavior
19136 * composite.c: Use int, not EMACS_INT, for characters.
19137 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19138 EMACS_INT, for values that are known to be in character range.
19139 This doesn't fix any bugs but is the usual style inside Emacs and
19140 may generate better code on 32-bit machines.
19142 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19143 This is for reasons similar to the recent CHAR_STRING fix.
19144 * charset.c (Fencode_char): Check that character arg is actually
19145 a character. Pass an int to ENCODE_CHAR.
19146 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19147 wider than 'int', as a compile-time check to prevent future regressions
19150 * character.c (char_string): Remove unnecessary casts.
19152 Make sure a 64-bit char is never passed to CHAR_STRING.
19153 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19154 by silently ignoring the top 32 bits, allowing some values
19155 that were far too large to be valid characters.
19156 * character.h: Include <verify.h>.
19157 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19158 arguments are no wider than unsigned, as a compile-time check
19159 to prevent future regressions in this area.
19161 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19162 (Fsubst_char_in_region):
19164 * xdisp.c (decode_mode_spec_coding):
19165 Adjust to CHAR_STRING's new requirement.
19166 * editfns.c (Finsert_char, Fsubst_char_in_region):
19167 * fns.c (concat): Check that character args are actually
19168 characters. Without this test, these functions did the wrong
19169 thing with wildly out-of-range values on 64-bit hosts.
19171 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19172 These casts should not be needed on 32-bit hosts, either.
19173 * keyboard.c (read_char):
19174 * lread.c (Fload): Remove casts to unsigned.
19176 * lisp.h (UNSIGNED_CMP): New macro.
19177 This fixes comparison bugs on 64-bit hosts.
19178 (ASCII_CHAR_P): Use it.
19179 * casefiddle.c (casify_object):
19180 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19181 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19182 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19183 * dispextern.h (FACE_FROM_ID):
19184 * keyboard.c (read_char): Use UNSIGNED_CMP.
19186 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19187 not to EMACS_INT, to avoid GCC warning.
19189 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19191 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19192 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19193 isn't needed on 32-bit machines.
19195 * buffer.c (Fgenerate_new_buffer_name):
19196 Use EMACS_INT for count, not int.
19197 (advance_to_char_boundary): Return EMACS_INT, not int.
19199 * data.c (Qcompiled_function): Now static.
19201 * window.c (window_body_lines): Now static.
19203 * image.c (gif_load): Rename local to avoid shadowing.
19205 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19206 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19207 * alloc.c (make_save_value): Integer argument is now of type
19208 ptrdiff_t, not int.
19209 (mark_object): Use ptrdiff_t, not int.
19210 * lisp.h (pD): New macro.
19211 * print.c (print_object): Use it.
19213 * alloc.c: Use EMACS_INT, not int, to count objects.
19214 (total_conses, total_markers, total_symbols, total_vector_size)
19215 (total_free_conses, total_free_markers, total_free_symbols)
19216 (total_free_floats, total_floats, total_free_intervals)
19217 (total_intervals, total_strings, total_free_strings):
19218 Now EMACS_INT, not int. All uses changed.
19219 (Fgarbage_collect): Compute overall total using a double, so that
19220 integer overflow is less likely to be a problem. Check for overflow
19221 when converting back to an integer.
19222 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19223 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19224 These were 'int' variables that could overflow on 64-bit hosts;
19225 they were never used, so remove them instead of repairing them.
19226 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19227 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19228 Previously, this ceilinged at INT_MAX, but that doesn't work on
19230 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19232 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19233 (allocate_vectorlike): Check for ptrdiff_t overflow.
19234 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19235 when a (possibly-narrower) signed value would do just as well.
19236 We prefer using signed arithmetic, to avoid comparison confusion.
19238 * alloc.c: Catch some string size overflows that we were missing.
19239 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19240 for convenience in STRING_BYTES_MAX.
19241 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19242 The definition here is exact; the one in lisp.h was approximate.
19243 (allocate_string_data): Check for string overflow. This catches
19244 some instances we weren't catching before. Also, it catches
19245 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19246 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19247 and ptrdiff_t and EMACS_INT are both 64 bits.
19249 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19250 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19251 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19253 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19255 * alloc.c (Fmake_string): Check for out-of-range init.
19257 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19259 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
19261 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
19263 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
19264 xg_get_default_scrollbar_width.
19266 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
19267 (int_gtk_range_get_value): Move to the scroll bar part of the file.
19268 (style_changed_cb): Call update_theme_scrollbar_width and call
19269 x_set_scroll_bar_default_width and xg_frame_set_char_size for
19270 all frames (Bug#8505).
19271 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
19272 Call gtk_window_set_resizable if HAVE_GTK3.

19274 and height if HAVE_GTK3 (Bug#8505).
19275 (scroll_bar_width_for_theme): New variable.
19276 (update_theme_scrollbar_width): New function.
19277 (xg_get_default_scrollbar_width): Move code to
19278 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
19279 (xg_initialize): Call update_theme_scrollbar_width.
19281 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
19283 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
19285 2011-06-12 Martin Rudalics <rudalics@gmx.at>
19287 * frame.c (make_frame): Call other_buffer_safely instead of
19290 * window.c (temp_output_buffer_show): Call display_buffer with
19291 second argument Vtemp_buffer_show_specifiers and reset latter
19292 immediately after the call.
19293 (Vtemp_buffer_show_specifiers): New variable.
19294 (auto_window_vscroll_p, next_screen_context_lines)
19295 (Vscroll_preserve_screen_position): Remove leading asterisks from

19478 Remove static from declaration of Qdelete_window, it's
19479 temporarily needed by Fbury_buffer.
19480 (replace_window): Don't assign orig_top_line and

19846 (display_prop_intangible_p): Reimplement to call
19847 handle_display_spec instead of single_display_spec_intangible_p.

19859 value of a `display' property is a "replacing spec".
19860 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19861 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

19891 * gnutls.c: Use Emacs's memory allocators.
19892 Without this change, the gnutls library would invoke malloc etc.
19893 directly, which causes problems on non-SYNC_INPUT hosts, and which
19894 runs afoul of improving memory_full behavior. (Bug#8761)
19895 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19896 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19897 xfree instead of the default malloc, realloc, free.
19898 (Fgnutls_boot): No need to check for memory allocation failure,
19899 since xmalloc does that for us.

19928 need to be updated by these changes.
19929 * fns.c (make_hash_table, maybe_resize_hash_table):
19930 Check for integer overflow with large hash tables.
19931 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19932 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19933 (SXHASH_REDUCE): New macro.
19934 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19935 Use it instead of discarding useful hash info with large hash values.
19936 (sxhash_float): New function.
19937 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19938 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19939 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19940 Rewrite to use FIXNUM_BITS, as this simplifies things.
19941 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19942 Adjust signatures to match updated version of code.
19943 (consing_since_gc): Now EMACS_INT, since a single hash table can
19944 use more than INT_MAX bytes.

19967 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19969 Don't force ./temacs to start in terminal mode.
19971 * frame.c (make_initial_frame): Initialize faces in all cases, not
19972 only when CANNOT_DUMP is defined.
19973 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19975 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19977 * dispnew.c (add_window_display_history): Use const for the string
19978 pointer. Remove declaration, not needed.
19980 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19982 Use 'inline', not 'INLINE'.
19983 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19984 * alloc.c, fontset.c (INLINE): Remove.
19985 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19986 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19987 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19988 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19989 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19991 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19993 Make it possible to run ./temacs.
19995 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19996 syms_of_callproc does the same thing. Remove test for
19997 "initialized", do it in the caller.
19998 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20000 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20002 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20003 (read_minibuf): Use get_minibuffer.
20004 (syms_of_minibuf): Use DEFSYM.
20005 (Qmetadata): New var.
20006 * data.c (Qbuffer): Don't make it static.
20007 (syms_of_data): Use DEFSYM.
20009 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20011 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20012 (CCL_CODE_MIN): New macro.
20014 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20016 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20018 * eval.c (Qdebug): Now static.
20019 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20020 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20021 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20023 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20025 * image.c: Various fixes to ImageMagick code comments.
20026 (Fimagemagick_types): Doc fix.
20028 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20030 Minor fixes prompted by GCC 4.6.0 warnings.
20032 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20034 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20035 (x_clipboard_manager_save_all): Move extern decl to ...
20036 * xterm.h: ... here, so that it can be checked for consistency.
20038 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20040 * xselect.c (x_clipboard_manager_save_frame)
20041 (x_clipboard_manager_save_all): New functions.
20042 (Fx_clipboard_manager_save): Lisp function deleted.
20044 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20045 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20047 * xterm.h: Update prototype.
20049 2011-05-28 William Xu <william.xwl@gmail.com>
20051 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20052 exiting (Bug#8239).
20054 2011-05-28 Jim Meyering <meyering@redhat.com>
20056 Avoid a sign-extension bug in crypto_hash_function.
20057 * fns.c (to_uchar): Define.
20058 (crypto_hash_function): Use it to convert some newly-signed
20059 variables to unsigned, to avoid sign-extension bugs. For example,
20060 without this change, (md5 "truc") would evaluate to
20061 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20062 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20063 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20065 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20067 Integer overflow fixes.
20069 * dbusbind.c: Serial number integer overflow fixes.
20070 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20071 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20072 to hold a serial number that is too large for a fixnum.
20073 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20074 Check for serial numbers out of range. Decode any serial number
20075 that was so large that it became a float. (Bug#8722)
20077 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20078 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20079 Use XFASTINT rather than XUINT when numbers are nonnegative.
20080 (xd_append_arg, Fdbus_method_return_internal):
20081 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20082 arguments, check that Lisp number is nonnegative, rather than
20083 silently wrapping negative numbers around. (Bug#8722)
20084 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20087 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20089 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20091 ccl: Add integer overflow checks.
20092 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20093 (IN_INT_RANGE): New macros.
20094 (ccl_driver): Use them to check for integer overflow when
20095 decoding a CCL program. Many of the new checks are whether XINT (x)
20096 fits in int; it doesn't always, on 64-bit hosts. The new version
20097 doesn't catch all possible integer overflows, but it's an
20098 improvement. (Bug#8719)
20100 * alloc.c (make_event_array): Use XINT, not XUINT.
20101 There's no need for unsigned here.
20103 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20104 This follows up to the 2011-05-06 change that substituted uintptr_t
20105 for EMACS_INT. This case wasn't caught back then.
20107 Rework Fformat to avoid integer overflow issues.
20108 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20109 now (part of C89). Include <verify.h>.
20110 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20111 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20112 (Fformat): Avoid the prepass trying to compute sizes; it was only
20113 approximate and thus did not catch overflow reliably. Instead, walk
20114 through the format just once, formatting and computing sizes as we go,
20115 checking for integer overflow at every step, and allocating a larger
20116 buffer as needed. Keep track separately whether the format is
20117 multibyte. Keep only the most-recently calculated precision, rather
20118 than them all. Record whether each argument has been converted to
20119 string. Use EMACS_INT, not int, for byte and char and arg counts.
20120 Support field widths and precisions larger than INT_MAX. Avoid
20121 sprintf's undefined behavior with conversion specifications such as %#d
20122 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20123 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20124 formatting out-of-range floating point numbers with int
20125 formats. (Bug#8668)
20127 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20129 * data.c: Avoid integer truncation in expressions involving floats.
20130 * data.c: Include <intprops.h>.
20131 (arith_driver): When there's an integer overflow in an expression
20132 involving floating point, convert the integers to floating point
20133 so that the resulting value does not suffer from catastrophic
20134 integer truncation. For example, on a 64-bit host (* 4
20135 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20136 Do not rely on undefined behavior after integer overflow.
20138 merge count_size_as_multibyte, parse_str_to_multibyte
20139 * character.c, character.h (count_size_as_multibyte):
20140 Rename from parse_str_to_multibyte; all uses changed.
20141 Check for integer overflow.
20142 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20143 since it's now a duplicate of the other. This is more of
20144 a character than a buffer op, so better that it's in character.c.
20145 * fns.c, print.c: Adjust to above changes.
20147 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20149 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20151 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20153 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20154 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20155 (x_clipboard_manager_save): Now static.
20156 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20158 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20159 (crypto_hash_function): Now static.
20160 Fix pointer signedness problems. Avoid unnecessary initializations.
20162 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20164 * termhooks.h (Vselection_alist): Make it terminal-local.
20166 * terminal.c (create_terminal): Initialize it.
20168 * xselect.c: Support for clipboard managers.
20169 (Vselection_alist): Move to termhooks.h as terminal-local var.
20170 (LOCAL_SELECTION): New macro.
20171 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20172 (symbol_to_x_atom): Remove gratuitous arg.
20173 (x_handle_selection_request, lisp_data_to_selection_data)
20174 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20175 (x_own_selection, x_get_local_selection, x_convert_selection):
20176 New arg, specifying work frame. Use terminal-local Vselection_alist.
20177 (some_frame_on_display): Delete unused function.
20178 (Fx_own_selection_internal, Fx_get_selection_internal)
20179 (Fx_disown_selection_internal, Fx_selection_owner_p)
20180 (Fx_selection_exists_p): New optional frame arg.
20181 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20182 (x_handle_selection_clear): Don't treat other terminals with the
20183 same keyboard specially. Use the terminal-local Vselection_alist.
20184 (x_clear_frame_selections): Use Frun_hook_with_args.
20186 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20188 * xterm.h: Add support for those atoms.
20190 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20192 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20193 (converted_selections, conversion_fail_tag): New global variables.
20194 (x_selection_request_lisp_error): Free the above.
20195 (x_get_local_selection): Remove unnecessary code.
20196 (x_reply_selection_request): Args changed; handle arbitrary array
20197 of converted selections stored in converted_selections.
20198 Separate the XChangeProperty and SelectionNotify steps.
20199 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20200 (x_convert_selection): New function.
20201 (x_handle_selection_event): Simplify.
20202 (x_get_foreign_selection): Don't ignore incoming requests while
20203 waiting for an answer; this will fail when we implement
20204 SAVE_TARGETS, and seems unnecessary anyway.
20205 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20206 (Vx_sent_selection_functions): Doc fix.
20208 2011-05-26 Leo Liu <sdl.web@gmail.com>
20210 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20212 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20214 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20216 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20217 for fringe update if it has periodic bitmap.
20218 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20219 and fringe_bitmap_periodic_p.
20221 * fringe.c (get_fringe_bitmap_data): New function.
20222 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20223 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20224 row. Mark glyph row for fringe update if periodicity changed.
20226 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20227 for fringe update unless it has periodic bitmap.
20229 2011-05-25 Kenichi Handa <handa@m17n.org>
20231 * xdisp.c (get_next_display_element): Set correct it->face_id for
20232 a static composition.
20234 2011-05-24 Leo Liu <sdl.web@gmail.com>
20237 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20239 * fns.c (crypto_hash_function, Fsha1): New function.
20240 (Fmd5): Use crypto_hash_function.
20241 (syms_of_fns): Add Ssha1.
20243 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20245 * gnutls.c: Remove unused macros.
20246 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20247 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20248 Remove macros that are defined and never used.
20249 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20251 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20253 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20254 (Fx_get_selection_internal): Minor cleanup.
20255 (Fx_own_selection_internal): Rename arguments for consistency with
20258 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20260 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20262 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20264 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20266 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20268 * dispnew.c (scrolling_window): Don't exclude the case that the
20269 last enabled row in the desired matrix touches the bottom boundary.
20271 2011-05-21 Glenn Morris <rgm@gnu.org>
20273 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20274 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20275 and add some more files.
20277 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20279 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20280 report_file_error introduced by the change from 2011-05-07.
20282 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20284 * systime.h (Time): Define only if emacs is defined.
20285 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20286 where the include path doesn't have X11/X.h by default. See
20287 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20289 2011-05-20 Kenichi Handa <handa@m17n.org>
20291 * composite.c (find_automatic_composition): Fix previous change.
20293 2011-05-20 Glenn Morris <rgm@gnu.org>
20295 * lisp.mk: New file, split from Makefile.in.
20296 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20297 (shortlisp): Remove.
20298 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20300 2011-05-19 Glenn Morris <rgm@gnu.org>
20302 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20303 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20304 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20305 (lisp): Set the order to that of loadup.el.
20306 (shortlisp): Make it a copy of $lisp.
20307 (SOME_MACHINE_LISP): Remove.
20308 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20309 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20311 2011-05-18 Kenichi Handa <handa@m17n.org>
20313 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20314 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20315 (find_automatic_composition): Mostly rewrite for efficiency.
20317 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20319 * makefile.w32-in: Update dependencies.
20321 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20323 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20324 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20326 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20328 Fix some integer overflow issues, such as string length overflow.
20330 * insdel.c (count_size_as_multibyte): Check for string overflow.
20332 * character.c (lisp_string_width): Check for string overflow.
20333 Use EMACS_INT, not int, for string indexes and lengths; in
20334 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20335 the resulting string length overflows an EMACS_INT; instead,
20336 report a string overflow if no precision given. When checking for
20337 precision exhaustion, use a check that cannot possibly have
20338 integer overflow. (Bug#8675)
20339 * character.h (lisp_string_width): Adjust to new signature.
20341 * alloc.c (string_overflow): New function.
20342 (Fmake_string): Use it. This doesn't change behavior, but saves
20343 a few bytes and will simplify future changes.
20344 * character.c (string_escape_byte8): Likewise.
20345 * lisp.h (string_overflow): New decl.
20347 Fixups, following up to the user-interface timestamp change.
20348 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20349 for UI timestamps, instead of unsigned long.
20350 * msdos.c (mouse_get_pos): Likewise.
20351 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20352 * w32gui.h (Time): Define by including "systime.h" rather than by
20353 declaring it ourselves. (Bug#8664)
20355 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20356 * image.c (clear_image_cache): Likewise.
20358 * term.c (term_mouse_position): Don't assume time_t wraparound.
20360 Be more systematic about user-interface timestamps.
20361 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20362 and sometimes 'EMACS_UINT', to represent these timestamps.
20363 This change causes it to use 'Time' uniformly, as that's what X uses.
20364 This makes the code easier to follow, and makes it easier to catch
20365 integer overflow bugs such as Bug#8664.
20366 * frame.c (Fmouse_position, Fmouse_pixel_position):
20367 Use Time, not unsigned long, for user-interface timestamps.
20368 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20369 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20370 * keyboard.h (last_event_timestamp): Likewise.
20371 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20372 * menu.h (xmenu_show): Likewise.
20373 * term.c (term_mouse_position): Likewise.
20374 * termhooks.h (struct input_event.timestamp): Likewise.
20375 (struct terminal.mouse_position_hook): Likewise.
20376 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20377 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20378 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20379 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20380 what it was before.
20381 * menu.h, termhooks.h: Include "systime.h", for Time.
20383 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20384 Don't assume that the difference between two unsigned long values
20385 can fit into an integer. At this point, we know button_down_time
20386 <= event->timestamp, so the difference must be nonnegative, so
20387 there's no need to cast the result if double-click-time is
20388 nonnegative, as it should be; check that it's nonnegative, just in
20389 case. This bug is triggered when events are more than 2**31 ms
20390 apart (about 25 days). (Bug#8664)
20392 * xselect.c (last_event_timestamp): Remove duplicate decl.
20393 (x_own_selection): Remove needless cast to unsigned long.
20395 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20396 that always fit in int. Use a sentinel instead of a counter, to
20397 avoid a temp and to allay GCC's concerns about possible int overflow.
20398 * frame.h (struct frame): Use int for menu_bar_items_used
20399 instead of EMACS_INT, since it always fits in int.
20401 * menu.c (grow_menu_items): Check for int overflow.
20403 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20405 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20406 Before, the code was not consistent. These values cannot exceed
20407 2**31 - 1 so there's no need to make them unsigned.
20408 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20409 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20410 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20412 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20414 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20415 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20416 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20417 presumably because the widths might not match.
20419 * window.c (size_window): Avoid needless test at loop start.
20421 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20423 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20425 2011-05-12 Drew Adams <drew.adams@oracle.com>
20427 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20429 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20431 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20432 `width' to `bar_area_x' and `bar_area_width', respectively.
20433 (x_scroll_run): Take account of fringe background extension.
20435 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20436 Rename local vars `left' and `width' to `bar_area_x' and
20437 `bar_area_width', respectively.
20438 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20439 background extension.
20441 2011-05-10 Jim Meyering <meyering@redhat.com>
20443 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20445 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20447 * image.c (Finit_image_library): Return t for built-in image types,
20448 like pbm and xbm. (Bug#8640)
20450 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20452 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20454 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20456 * w32console.c (Fset_screen_color): Doc fix.
20457 (Fget_screen_color): New function.
20458 (syms_of_ntterm): Defsubr it.
20460 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20461 unlink the temporary file if Fcall_process didn't create it in the
20463 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20464 child process will be redirected to a file specified with `:file'.
20465 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20466 cue to call_process_cleanup not to close that handle.
20468 2011-05-07 Ben Key <bkey76@gmail.com>
20470 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20471 one of two shell specific rules, either bootstrap-temacs-CMD or
20472 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20473 to the previous implementation of the bootstrap-temacs rule.
20474 The bootstrap-temacs-CMD rule is similar to the previous
20475 implementation of the bootstrap-temacs rule except that it
20476 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20479 These changes, along with some changes to nt/configure.bat,
20480 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20481 earlier fix to add support for --cflags and --ldflags options
20482 that include quotes so that it works whether make uses cmd or
20485 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20487 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20488 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20490 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20491 a string. Handle both cases.
20492 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20493 (Fdbus_register_method): Use Qinvalid_function.
20495 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20497 * makefile.w32-in: Update dependencies.
20498 (LISP_H): Add inttypes.h and stdin.h.
20499 (PROCESS_H): Add unistd.h.
20501 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20503 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20504 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20506 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20508 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20510 * term.c (vfatal): Remove stray call to va_end.
20511 It's not needed and the C Standard doesn't allow it here anyway.
20513 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20514 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20516 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20519 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20521 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20523 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20525 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20527 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20529 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20530 * charset.c (Fdefine_charset_internal): Don't initialize
20531 charset.code_space[15]. The value was garbage, on hosts with
20532 32-bit int (Bug#8600).
20534 * lread.c (read_integer): Be more consistent with string-to-number.
20535 Use string_to_number to do the actual conversion; this avoids
20536 rounding errors and fixes some other screwups. Without this fix,
20537 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20538 (digit_to_number): Move earlier, for benefit of read_integer.
20539 Return -1 if the digit is out of range for the base, -2 if it is
20540 not a digit in any supported base. (Bug#8602)
20542 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20544 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20545 to match comment at start of function. This also removes a
20546 GCC warning about overflow in a 32+64-bit port.
20548 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20550 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20551 Reported by Stefan Monnier in
20552 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20553 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20554 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20556 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20557 (EMACS_UINTPTR): Likewise, with uintptr_t.
20559 * lisp.h: Prefer 64-bit EMACS_INT if available.
20560 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20561 on 32-bit hosts that have 64-bit int, so that they can access
20563 However, temporarily disable this change unless the temporary
20564 symbol WIDE_EMACS_INT is defined.
20566 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20568 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20569 This removes an assumption that EMACS_INT and long are the same
20570 width as pointers. The assumption is true for Emacs porting targets
20571 now, but we want to make other targets possible.
20572 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20573 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20574 In the rest of the code, change types of integers that hold casted
20575 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20576 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20577 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20578 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20579 No need to cast type when ORing.
20580 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20581 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20582 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20583 assume EMACS_INT is the same width as char *.
20584 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20585 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20586 Remove no-longer-needed casts.
20587 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20588 (xg_tool_bar_help_callback, xg_make_tool_item):
20589 Use EMACS_INTPTR to hold an integer
20590 that will be cast to void *; this can avoid a GCC warning
20591 if EMACS_INT is not the same width as void *.
20592 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20593 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20594 (current_message_1, set_message_1):
20595 Use a local to convert to proper width without a cast.
20596 * xmenu.c (dialog_selection_callback): Likewise.
20598 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20599 Also, don't assume VALBITS / RAND_BITS is less than 5,
20600 and don't rely on undefined behavior when shifting a 1 left into
20602 * lisp.h (get_random): Change signature to match.
20604 * lread.c (hash_string): Use size_t, not int, for hash computation.
20605 Normally we prefer signed values; but hashing is special, because
20606 it's better to use unsigned division on hash table sizes so that
20607 the remainder is nonnegative. Also, size_t is the natural width
20608 for hashing into memory. The previous code used 'int', which doesn't
20609 retain enough info to hash well into very large tables.
20610 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20612 * dbusbind.c: Don't possibly lose pointer info when converting.
20613 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20614 Use XPNTR rather than XHASH, so that the high-order bits of
20615 the pointer aren't lost when converting through void *.
20617 * eval.c (Fautoload): Don't double-shift a pointer.
20619 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20621 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20623 * gnutls.c (DEF_GNUTLS_FN):
20624 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20626 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20628 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20631 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20633 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20634 New version that can reserve upto 2GB of heap space.
20636 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20638 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20640 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20642 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20643 `gnutls_certificate_set_x509_key_file'.
20645 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20647 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20648 Update dependencies.
20650 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20652 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20653 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20654 Remove unused parameter `fildes'.
20655 * process.c (read_process_output, send_process): Don't pass it.
20657 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20659 Fix previous change: the library cache is defined in w32.c.
20660 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20661 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20663 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20665 Implement dynamic loading of GnuTLS on Windows.
20667 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20668 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20669 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20672 * gnutls.c (Qgnutls_dll): Define.
20673 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
20674 (gnutls_*): Declare function pointers.
20675 (init_gnutls_functions): New function to initialize function pointers.
20676 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
20677 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
20678 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20679 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
20680 (emacs_gnutls_write, emacs_gnutls_read)
20681 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20682 (Fgnutls_available_p): New function.
20683 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
20684 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
20685 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
20687 * image.c: Include w32.h.
20688 (Vimage_type_cache): Delete.
20689 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
20690 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
20691 (w32_delayed_load): Move to w32.c.
20693 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20695 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20696 (w32_delayed_load): Move from image.c. When loading a library, record
20697 its filename in the :loaded-from property of the library id.
20698 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20699 Initialize and staticpro them.
20700 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20702 * process.c: Include lisp.h before w32.h, not after.
20703 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20704 instead of gnutls_record_check_pending.
20706 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20708 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20710 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20711 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20714 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20716 * xterm.c (x_set_frame_alpha): Do not set property on anything
20717 else than FRAME_X_OUTER_WINDOW (Bug#8608).

20737 * callproc.c: Indentation fixup.
20739 * sysdep.c (wait_for_termination_1): Make static.
20740 (wait_for_termination, interruptible_wait_for_termination):
20741 Move after wait_for_termination_1.
20743 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
20745 * sysdep.c (interruptible_wait_for_termination): New function
20746 which is like wait_for_termination, but allows keyboard
20749 * callproc.c (Fcall_process): Add (:file "file") as an option for
20751 (Fcall_process_region): Ditto.
20753 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20755 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20756 rather than `XVECTOR (FOO)->size'.
20758 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20759 inttypes.h, as a gnulib replacement is used if it not available in
20762 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20764 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20765 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20766 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20768 * coding.c (coding_alloc_by_realloc): Error out if destination
20769 will grow beyond MOST_POSITIVE_FIXNUM.
20770 (decode_coding_emacs_mule): Abort if there isn't enough place in

20781 %llo or %llx format is passed. (Bug#8545)
20783 * window.c (window_scroll_line_based): Use a marker instead of
20784 simple variables to record original value of point. (Bug#7952)
20786 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20787 produced by %s or %c overflows available buffer space. (Bug#8545)
20789 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20791 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20792 (SIZE_MAX): Move defn after all includes, as they might #define it.
20794 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20796 * w32.c (init_environment): Warn about defaulting HOME to C:\.

20816 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20818 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20820 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20822 * makefile.w32-in: Update dependencies.
20824 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20826 Improve `doprnt' and its usage. (Bug#8545)
20827 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20828 `format_end'. Remove support for %l as a conversion specifier.
20829 Don't use xrealloc. Improve diagnostics when the %l size modifier
20830 is used. Update the commentary.
20832 * eval.c (verror): Simplify calculation of size_t.
20834 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20837 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20839 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20842 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20844 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20845 This makes this file independent of the recent pseudovector change.
20847 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20849 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20851 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20852 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20853 Remove unused local.
20854 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20856 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20857 GCC 4.6.0 optimizes based on type-based alias analysis.
20858 For example, if b is of type struct buffer * and v of type struct
20859 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20860 != &v->size, and therefore "v->size = 1; b->size = 2; return
20861 v->size;" must therefore return 1. This assumption is incorrect
20862 for Emacs, since it type-puns struct Lisp_Vector * with many other
20863 types. To fix this problem, this patch adds a new type struct
20864 vectorlike_header that documents the constraints on layout of vectors
20865 and pseudovectors, and helps optimizing compilers not get fooled
20866 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20867 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20868 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20870 (XSETPVECTYPE): Rewrite in terms of new macro.
20871 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20872 This is a bit clearer, and further avoids the possibility of
20873 undesirable aliasing.
20874 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20875 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20876 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20877 since Lisp_Subr is a special case (no "next" field).
20878 (ASIZE): Now uses header.size rather than size.
20879 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20880 to avoid the hassle of writing XVECTOR (foo)->header.size.
20881 (struct vectorlike_header): New type.
20882 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20883 object, to help avoid aliasing.
20884 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20885 (SUBRP): Likewise, since Lisp_Subr is a special case.
20886 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20887 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20888 (struct Lisp_Hash_Table): Combine first two members into a single
20889 struct vectorlike_header member. All uses of "size" and "next" members
20890 changed to be "header.size" and "header.next".
20891 * buffer.h (struct buffer): Likewise.
20892 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20893 * frame.h (struct frame): Likewise.
20894 * process.h (struct Lisp_Process): Likewise.
20895 * termhooks.h (struct terminal): Likewise.
20896 * window.c (struct save_window_data, struct saved_window): Likewise.
20897 * window.h (struct window): Likewise.
20898 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20899 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20900 * buffer.c (init_buffer_once): Likewise.
20901 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20903 * process.c (Fformat_network_address): Use local var for size,
20906 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20908 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20909 * data.c (atof): Remove decl; no longer used or needed.
20910 (digit_to_number): Move to lread.c.
20911 (Fstring_to_number): Use new string_to_number function, to be
20912 consistent with how the Lisp reader treats infinities and NaNs.
20913 Do not assume that floating-point numbers represent EMACS_INT
20914 without losing information; this is not true on most 64-bit hosts.
20915 Avoid double-rounding errors, by insisting on integers when
20916 parsing non-base-10 numbers, as the documentation specifies.
20917 * lisp.h (string_to_number): New decl, replacing ...
20918 (isfloat_string): Remove.
20919 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20920 (read1): Do not accept +. and -. as integers; this
20921 appears to have been a coding error. Similarly, do not accept
20922 strings like +-1e0 as floating point numbers. Do not report
20923 overflow for integer overflows unless the base is not 10 which
20924 means we have no simple and reliable way to continue.
20925 Break out the floating-point parsing into a new
20926 function string_to_number, so that Fstring_to_number parses
20927 floating point numbers consistently with the Lisp reader.
20928 (digit_to_number): Move here from data.c. Make it static inline.
20929 (E_CHAR, EXP_INT): Remove, replacing with ...
20930 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20931 (string_to_number): New function, replacing isfloat_string.
20932 This function checks for valid syntax and produces the resulting
20933 Lisp float number too. Rework it so that string-to-number
20934 no longer mishandles examples like "1.0e+". Use strtoumax,
20935 so that overflow for non-base-10 numbers is reported only when
20936 there's no portable and simple way to convert to floating point.
20938 * textprop.c (set_text_properties_1): Rewrite for clarity,
20939 and to avoid GCC warning about integer overflow.
20941 * intervals.h (struct interval): Use EMACS_INT for members
20942 where EMACS_UINT might cause problems. See
20943 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20944 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20945 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20947 (offset_intervals): Tell GCC not to worry about length overflow
20948 when negating a negative length.
20950 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20951 (overrun_check_free): Likewise.
20953 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20954 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20957 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20958 (gnutls_make_error): Rename local to avoid shadowing.
20959 (gnutls_emacs_global_deinit): ifdef out; not used.
20960 (Fgnutls_boot): Use const for pointer to readonly storage.
20961 Comment out unused local. Fix pointer signedness problems.
20963 * lread.c (openp): Don't stuff size_t into an 'int'.
20964 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20965 about possible signed overflow.
20967 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20968 (GDK_KEY_g): Don't define if already defined.
20969 (xg_prepare_tooltip): Avoid pointer signedness problem.
20970 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20972 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20973 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20975 * xfns.c (Fx_window_property): Simplify a bit,
20976 to make a bit faster and to avoid GCC 4.6.0 warning.
20977 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20979 * fns.c (internal_equal): Don't assume size_t fits in int.
20981 * alloc.c (compact_small_strings): Tighten assertion a little.
20983 Replace pEd with more-general pI, and fix some printf arg casts.
20984 * lisp.h (pI): New macro, generalizing old pEd macro to other
20985 conversion specifiers. For example, use "...%"pI"d..." rather
20986 than "...%"pEd"...".
20987 (pEd): Remove. All uses replaced with similar uses of pI.
20988 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20989 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20990 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20991 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20992 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20993 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20994 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20996 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20997 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20998 * print.c (safe_debug_print, print_object): Likewise.
20999 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21001 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21002 avoiding the 0 flag, which is not portable.
21003 * process.c (Fmake_network_process): Use pI to avoid cast.
21004 * region-cache.c (pp_cache): Likewise.
21005 * xdisp.c (decode_mode_spec): Likewise.
21006 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21007 behavior on 64-bit hosts with printf arg.
21008 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21009 (x_stop_queuing_selection_requests): Likewise.
21010 (x_get_window_property): Don't truncate byte count to an 'int'
21013 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21014 here, since it parses constructs like leading '-' and spaces,
21015 which are not wanted; and it overflows with large numbers.
21016 Instead, simply match F[0-9]+, which is what is wanted anyway.
21018 * alloc.c: Remove unportable assumptions about struct layout.
21019 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21020 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21021 (allocate_vectorlike, make_pure_vector): Use the new macros,
21022 plus offsetof, to remove unportable assumptions about struct layout.
21023 These assumptions hold on all porting targets that I know of, but
21024 they are not guaranteed, they're easy to remove, and removing them
21025 makes further changes easier.
21027 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21028 This doesn't fix a bug but makes the code clearer.
21029 (string_overrun_cookie): Now const. Use initializers that
21030 don't formally overflow signed char, to avoid warnings.
21031 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21032 can cause Emacs to crash when string overrun checking is enabled.
21033 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21034 multiple of sizeof (EMACS_INT); it need not be, if
21035 alignof(EMACS_INT) < sizeof (EMACS_INT).
21036 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21038 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

21042 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
21044 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
21045 supposed to be handshaking. (Bug#8556)
21046 Reported by Paul Eggert <eggert@cs.ucla.edu>.
21048 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

21053 (handle_user_signal): Break into debugger when debug-on-event
21054 matches the current signal symbol.
21056 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
21058 * alloc.c (check_sblock, check_string_bytes)
21059 (check_string_free_list): Convert to standard C.
21061 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
21063 * w32.c (emacs_gnutls_push): Fix typo.
21065 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21067 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21068 "cast to pointer from integer of different size".
21070 Improve doprnt and its use in verror. (Bug#8545)
21071 * doprnt.c (doprnt): Document the set of format control sequences
21072 supported by the function. Use SAFE_ALLOCA instead of always
21075 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21076 is one byte too soon. Don't use xrealloc; instead xfree and
21079 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21081 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21084 * gnutls.c: Renamed global_initialized to
21085 gnutls_global_initialized. Added internals for the
21086 :verify-hostname-error, :verify-error, and :verify-flags
21087 parameters of `gnutls-boot' and documented those parameters in the
21088 docstring. Start callback support.
21089 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21090 unless a fatal error occurred. Call gnutls_alert_send_appropriate
21091 on error. Return error code.
21092 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
21093 (emacs_gnutls_read): Likewise.
21094 (Fgnutls_boot): Return handshake error code.
21095 (emacs_gnutls_handle_error): New function.
21096 (wsaerror_to_errno): Likewise.

21107 buffered some data internally if no FDs are set for TLS
21110 * makefile.w32-in (OBJ2): Add gnutls.$(O).

21158 <char-direction-table>: Deleted.
21160 2011-04-23 Eli Zaretskii <eliz@gnu.org>
21162 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
21163 * doprnt.c: Include limits.h.
21164 (SIZE_MAX): New macro.
21165 (doprnt): Return a size_t value. 2nd arg is now size_t.
21166 Many local variables are now size_t instead of int or unsigned.
21167 Improve overflow protection. Support `l' modifier for integer
21168 conversions. Support %l conversion. Don't assume an EMACS_INT
21169 argument for integer conversions and for %c.
21171 * lisp.h (doprnt): Restore prototype.
21173 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
21174 $(SRC)/character.h.
21176 * Makefile.in (base_obj): Add back doprnt.o.
21178 * deps.mk (doprnt.o): Add back prerequisites.
21179 (callint.o): Depend on character.h.
21181 * eval.c (internal_lisp_condition_case): Include the handler
21182 representation in the error message.
21183 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
21184 when breaking from the loop.
21186 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
21188 * callint.c (Fcall_interactively): When displaying error message
21189 about invalid control letter, pass the character's codepoint, not
21190 a pointer to its multibyte form. Improve display of the character
21191 in octal and display also its hex code.
21193 * character.c (char_string): Use %x to display the (unsigned)
21194 codepoint of an invalid character, to avoid displaying a bogus
21197 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21198 `error', not SYMBOL_NAME itself.
21200 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
21201 character arguments to `error'.
21203 * charset.c (check_iso_charset_parameter): Fix incorrect argument
21204 to `error' in error message about FINAL_CHAR argument. Make sure
21205 FINAL_CHAR is a character, and use %c when it is passed as
21206 argument to `error'.

21270 Define only if needed.
21272 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
21273 by pacifying GCC about it. Maybe it's time to retire it?
21274 * xfaces.c (USG, __TIMEVAL__): Likewise.
21276 * dispextern.h (struct redisplay_interface): Rename param
21277 to avoid shadowing.
21278 * termhooks.h (struct terminal): Likewise.
21279 * xterm.c (xembed_send_message): Likewise.
21281 * insdel.c (make_gap_smaller): Define only if

21741 * ccl.h (check_ccl_update, Vccl_program_table): Remove decls.
21742 * ccl.c (Vccl_program_table): Now static.
21743 (check_ccl_update): Remove; unused.
21745 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
21746 * category.h: ... from here.
21747 * category.c (check_category_table, set_category_set): Now static.
21749 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
21750 * lisp.h: Remove these decls.
21752 * buffer.c (buffer_count): Remove unused var.
21754 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
21755 so that it's not optimized away.
21756 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
21757 * dispextern.h (bidi_dump_cached_states): Remove, since it's
21758 exported only to the debugger.
21760 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
21761 * atimer.h (run_all_atimers): Remove; not exported.
21763 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
21764 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
21765 was inaccessible from Lisp.
21766 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
21767 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
21769 alloc.c: Import and export fewer symbols, and remove unused items.
21770 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
21772 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
21773 it's not optimized away by whole-program optimization.
21774 (message_enable_multibyte, free_misc): Remove.
21775 (catchlist, handlerlist, mark_backtrace):
21776 Declare only if BYTE_MARK_STACK.
21777 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
21778 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
21779 (message_enable_multibyte): Remove decl.
21780 (free_misc, interval_free_list, float_block, float_block_index):

21782 (cons_free_list, last_marked_index):
21784 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
21785 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
21786 (mark_backtrace): Define only if BYTE_MARK_STACK.
21787 * xdisp.c (message_enable_multibyte): Now static.
21789 Declare Lisp_Object Q* variables to be 'static' if not exported.
21790 This makes it easier for human readers (and static analyzers)
21791 to see whether these variables are used from other modules.
21792 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
21793 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
21794 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

21797 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
21798 * xmenu.c, xselect.c:
21799 Declare Q* vars static if they are not used in other modules.
21800 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
21801 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
21802 Remove decls of unexported vars.
21803 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21805 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21807 Make Emacs functions such as Fatom 'static' by default.
21808 This makes it easier for human readers (and static analyzers)
21809 to see whether these functions can be called from other modules.
21810 DEFUN now defines a static function. To make the function external
21811 so that it can be used in other C modules, use the new macro DEFUE.
21812 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21813 (Finit_image_library):
21814 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21815 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21816 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21817 Remove decls, since these functions are now static.
21818 (Funintern, Fget_internal_run_time): New decls, since these functions
21819 were already external.
21821 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21822 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

21828 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21829 Mark functions with DEFUE instead of DEFUN,
21830 if they are used in other modules.
21831 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21832 decls for now-static functions.
21833 * buffer.h (Fdelete_overlay): Remove decl.
21834 * callproc.c (Fgetenv_internal): Mark as internal.
21835 * composite.c (Fremove_list_of_text_properties): Remove decl.

21841 (Funintern): Remove extern decl; now in .h file where it belongs.
21842 * fileio.c (Fmake_symbolic_link): New forward static decl.
21843 * image.c (Finit_image_library): New forward static decl.
21844 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21845 * intervals.h (Fprevious_property_change):
21846 (Fremove_list_of_text_properties): Remove decls.
21847 * keyboard.c (Fthis_command_keys): Remove decl.
21848 (Fcommand_execute): New forward static decl.
21849 * keymap.c (Flookup_key): New forward static decl.
21850 (Fcopy_keymap): Now static.
21851 * keymap.h (Flookup_key): Remove decl.
21852 * process.c (Fget_process): New forward static decl.
21853 (Fprocess_datagram_address): Mark as internal.

21864 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
21866 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21869 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21871 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21872 when at ZV. (Bug#8487)
21874 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21876 * charset.c (Fclear_charset_maps): Use xfree instead of free.
21878 * keyboard.c (parse_tool_bar_item): Likewise.
21879 * sound.c (sound_cleanup, alsa_close): Likewise.
21880 * termcap.c (tgetent): Likewise.
21881 * xfns.c (x_default_font_parameter): Likewise.
21882 * xsettings.c (read_and_apply_settings): Likewise.
21884 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21885 (overrun_check_free): Protoize.
21887 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21889 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21890 since callers should never pass a negative size.
21891 Change the signature to match that of plain 'read' and 'write'; see
21892 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21893 * lisp.h: Update prototypes of emacs_write and emacs_read.
21895 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21897 * xdisp.c (redisplay_window): Don't try to determine the character
21898 position of the scroll margin if the window start point w->startp
21899 is outside the buffer's accessible region. (Bug#8468)
21901 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21903 Fix write-region and its subroutines for buffers > 2GB.
21904 * fileio.c (a_write, e_write): Modify declaration of arguments and
21905 local variables to support buffers larger than 2GB.
21906 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21908 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21909 argument, local variables, and return value.
21911 * lisp.h: Update prototypes of emacs_write and emacs_read.
21913 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21915 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21917 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21919 Fix more problems found by GCC 4.6.0's static checks.
21921 * xdisp.c (vmessage): Use a better test for character truncation.
21923 * charset.c (load_charset_map): <, not <=, for optimization,
21924 and to avoid potential problems with integer overflow.
21925 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21926 * casetab.c (set_identity, shuffle): Likewise.
21927 * editfns.c (Fformat): Likewise.
21928 * syntax.c (skip_chars): Likewise.
21930 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21931 This also lets GCC 4.6.0 generate slightly better loop code.
21933 * callint.c (Fcall_interactively): <, not <=, for optimization.
21934 (Fcall_interactively): Count the number of arguments produced,
21935 not the number of arguments given. This is simpler and lets GCC
21936 4.6.0 generate slightly better code.
21938 * ftfont.c: Distingish more carefully between FcChar8 and char.
21939 The previous code passed unsigned char * to a functions like
21940 strlen and xstrcasecmp that expect char *, which does not
21941 conform to the C standard.
21942 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21943 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21944 char * when the C standard requires it.
21946 * keyboard.c (read_char): Remove unused var.
21948 * eval.c: Port to Windows vsnprintf (Bug#8435).
21949 Include <limits.h>.
21950 (SIZE_MAX): Define if the headers do not.
21951 (verror): Do not give up if vsnprintf returns a negative count.
21952 Instead, grow the buffer. This ports to Windows vsnprintf, which
21953 does not conform to C99. Problem reported by Eli Zaretskii.
21954 Also, simplify the allocation scheme, by avoiding the need for
21955 calling realloc, and removing the ALLOCATED variable.
21957 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21959 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21960 But keep the doprint source code for now, as we might revamp it
21961 and use it again (Bug#8435).
21962 * lisp.h (doprnt): Remove.
21963 * Makefile.in (base_obj): Remove doprnt.o.
21964 * deps.mk (doprnt.o): Remove.
21966 error: Print 32- and 64-bit integers portably (Bug#8435).
21967 Without this change, on typical 64-bit hosts error ("...%d...", N)
21968 was used to print both 32- and 64-bit integers N, which relied on
21969 undefined behavior.
21970 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21971 * lisp.h (error, verror): Mark as printf-like functions.
21972 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21973 Report overflow in size calculations when allocating printf buffer.
21974 Do not truncate output string at its first null byte.
21975 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21976 Truncate the output at a character boundary, since vsnprintf does not
21978 * charset.c (check_iso_charset_parameter): Convert internal
21979 character to string before calling 'error', since %c now has the
21981 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21982 overflow when computing char to be passed to 'error'. Do not
21983 pass Lisp_Object to 'error'; pass the integer instead.
21984 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21985 formatted with plain %d.
21987 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21989 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21991 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21993 * xterm.c (x_catch_errors): Remove duplicate declaration.
21995 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21997 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21999 2011-04-10 Jim Meyering <meyering@redhat.com>
22001 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22002 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22003 return ssize_t not "int", and use size_t as the buffer length.
22004 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22005 * gnutls.h: Update declarations.
22006 * process.c (read_process_output): Use ssize_t, to match.
22007 (send_process): Likewise.
22009 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22011 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22013 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22015 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22016 Use unsigned char, to match FcChar8 type definition.
22018 * xterm.c (handle_one_xevent):
22019 * xmenu.c (create_and_show_popup_menu):
22020 * xselect.c (x_decline_selection_request)
22021 (x_reply_selection_request): Avoid type-punned deref of X events.
22023 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22025 Fix some uses of `int' instead of EMACS_INT.
22026 * search.c (string_match_1, fast_string_match)
22027 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22028 (scan_buffer, find_next_newline_no_quit)
22029 (find_before_next_newline, search_command, Freplace_match)
22030 (Fmatch_data): Make some `int' variables be EMACS_INT.
22032 * xdisp.c (display_count_lines): 3rd argument and return value now
22033 EMACS_INT. All callers changed.
22034 (pint2hrstr): Last argument is now EMACS_INT.
22036 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22037 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22038 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
22039 (decode_coding_utf_16, decode_coding_emacs_mule)
22040 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
22041 (decode_coding_ccl, decode_coding_charset)
22042 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
22043 (decode_coding_iso_2022, decode_coding_emacs_mule)
22044 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
22045 <char_offset, last_offset>: Declare EMACS_INT.

22049 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22050 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22052 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22053 (encode_invocation_designation): Last argument P_NCHARS is now
22055 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22056 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22058 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22061 * ccl.c (Fccl_execute_on_string): Declare some variables
22064 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22066 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22068 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22070 * process.c (Fformat_network_address): Doc fix.
22072 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22074 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22076 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22078 * keyboard.c (read_char): Call Lisp function help-form-show,
22079 instead of using internal_with_output_to_temp_buffer.
22080 (Qhelp_form_show): New var.
22081 (syms_of_keyboard): Use DEFSYM macro.
22083 * print.c (internal_with_output_to_temp_buffer): Function deleted.

22087 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
22089 * process.c (Flist_processes): Remove to Lisp.
22090 (list_processes_1): Delete.
22092 2011-04-06 Eli Zaretskii <eliz@gnu.org>
22094 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22096 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22098 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22100 Fix more problems found by GCC 4.6.0's static checks.
22102 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
22104 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22106 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22108 * xdisp.c (vmessage): Mark as a printf-like function.
22110 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
22112 * sound.c (sound_warning): Don't crash if arg contains a printf format.
22114 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
22115 printf-like functions.
22116 (tiff_load): Add casts to remove these marks before passing them
22117 to system-supplied API.
22119 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22121 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22122 This avoids several warnings with gcc -Wstrict-overflow.
22123 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22124 directly, rather than having caller test rule sign. This avoids
22125 some unnecessary tests.
22126 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22127 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22128 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22130 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22131 (xfont_open): Avoid unnecessary tests.
22133 * composite.c (composition_gstring_put_cache): Use unsigned integer.

22145 since the condition is always true at first.
22147 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22148 (interval_deletion_adjustment): Return unsigned value.
22151 * process.c (list_processes_1, create_pty, read_process_output):

22153 (create_pty): Remove unnecessary "volatile"s.
22154 (Fnetwork_interface_info): Avoid possibility of int overflow.
22155 (read_process_output): Do adaptive read buffering even if carryover.
22156 (read_process_output): Simplify nbytes computation if buffered.

22167 * print.c (print_error_message): Avoid int overflow.
22169 * font.c (font_list_entities): Redo for clarity,
22170 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

22185 (wordify): Omit three unnecessary tests.
22187 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

22192 * dired.c (file_name_completion): Remove var that is set but not used.
22194 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22196 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22197 (Finsert_file_contents): Remove unnecessary code checking fd.
22199 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22200 Check for integer overflow on size calculations.
22202 * buffer.c (Fprevious_overlay_change): Remove var that is set
22205 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22206 Remove vars that are set but not used.
22207 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22208 (timer_check_2): Mark vars as initialized.
22210 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22212 * image.c (lookup_image): Remove var that is set but not used.
22213 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22215 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22216 that are set but not used.
22218 * xfns.c (make_invisible_cursor): Don't return garbage
22219 if XCreateBitmapFromData fails (Bug#8410).
22221 * xselect.c (x_get_local_selection, x_handle_property_notify):
22222 Remove vars that are set but not used.
22224 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
22225 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
22227 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
22228 Remove var that is set but not used.
22229 (scroll_bar_windows_size): Now size_t, not int.
22230 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
22231 Check for overflow.
22233 * xfaces.c (realize_named_face): Remove vars that are set but not used.
22234 (map_tty_color) [!defined MSDOS]: Likewise.
22236 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22238 * coding.c: Remove vars that are set but not used.
22239 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22240 All callers changed.
22241 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22242 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22243 (decode_coding_charset): Remove vars that are set but not used.
22245 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22246 that is set but not used.
22248 * print.c (print_object): Remove var that is set but not used.
22250 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22251 The gnulib version avoids calling malloc in the usual case,
22252 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22253 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22254 * filelock.c (current_lock_owner): Likewise.
22255 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22256 * sysdep.c: Include allocator.h, careadlinkat.h.
22257 (emacs_no_realloc_allocator): New static constant.
22258 (emacs_readlink): New function.
22259 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22260 ../lib/careadlinkat.h.
22262 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22264 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22265 first non-nil return value).

22286 do not dereference NULL upon failed strdup
22287 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22288 (ns_get_family): Likewise.
22290 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22292 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
22294 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
22296 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
22299 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
22301 Add lexical binding.
22303 * window.c (Ftemp_output_buffer_show): New fun.
22304 (Fsave_window_excursion):
22305 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
22307 * lread.c (lisp_file_lexically_bound_p): New function.
22308 (Fload): Bind Qlexical_binding.
22309 (readevalloop): Remove `evalfun' arg.
22310 Bind Qinternal_interpreter_environment.
22311 (Feval_buffer): Bind Qlexical_binding.
22312 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
22314 (syms_of_lread): Declare `lexical-binding'.
22316 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22318 * keyboard.c (eval_dyn): New fun.
22319 (menu_item_eval_property): Use it.
22321 * image.c (parse_image_spec): Use Ffunctionp.
22323 * fns.c (concat, mapcar1): Accept byte-code-functions.
22325 * eval.c (Fsetq): Handle lexical vars.
22326 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22327 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22328 (FletX, Flet): Obey lexical binding.
22329 (Fcommandp): Handle closures.
22330 (Feval): New `lexical' arg.
22331 (eval_sub): New function extracted from Feval. Use it almost
22332 everywhere where Feval was used. Look up vars in lexical env.
22334 (Ffunctionp): Move from subr.el.
22335 (Ffuncall): Handle closures.
22336 (apply_lambda): Remove `eval_flags'.
22337 (funcall_lambda): Handle closures and new byte-code-functions.
22338 (Fspecial_variable_p): New function.
22339 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22340 but without exporting it to Lisp.
22342 * doc.c (Fdocumentation, store_function_docstring):
22343 * data.c (Finteractive_form): Handle closures.
22345 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22348 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22350 (exec_byte_code): New function extracted from Fbyte_code to handle new
22351 calling convention for byte-code-functions. Add new byte-codes.
22353 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22355 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22357 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22359 * xdisp.c (redisplay_internal): Fix prototype.
22361 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22363 * xdisp.c (SCROLL_LIMIT): New macro.
22364 (try_scrolling): Use it when setting scroll_limit.
22365 Limit scrolling to 100 screen lines.
22366 (redisplay_window): Even when falling back on "recentering",
22367 position point in the window according to scroll-conservatively,
22368 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22370 (try_scrolling): When point is above the window, allow searching
22371 as far as scroll_max, or one screenful, to compute vertical
22372 distance from PT to the scroll margin position. This prevents
22373 try_scrolling from unnecessarily failing when
22374 scroll-conservatively is set to a value slightly larger than the
22375 window height. Clean up the case of PT below the margin at bottom
22376 of window: scroll_max can no longer be INT_MAX. When aggressive
22377 scrolling is in use, don't let point enter the opposite scroll
22378 margin as result of the scroll.
22379 (syms_of_xdisp) <scroll-conservatively>: Document the
22380 threshold of 100 lines for never-recentering scrolling.
22382 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22384 * dispextern.h (move_it_by_lines):
22385 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

22387 (message_log_check_duplicate): Remove parameters `prev_bol' and
22388 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22389 (redisplay_internal): Remove parameter `preserve_echo_area',
22390 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22392 * indent.c (Fvertical_motion):
22393 * window.c (window_scroll_pixel_based, Frecenter):
22394 Don't pass `need_y_p' to `move_it_by_lines'.
22396 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22398 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22399 steal a few bits to be more compact.
22400 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22401 Remove unneeded casts.
22403 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22405 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22407 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22408 binding" message (bug#7967).
22410 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22412 Fix more problems found by GCC 4.6.0's static checks.
22414 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22415 Remove unused local var.
22417 * editfns.c (Fmessage_box): Remove unused local var.
22419 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22420 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22421 Omit unused local vars.
22422 * window.c (shrink_windows): Omit unused local var.
22423 * menu.c (digest_single_submenu): Omit unused local var.
22424 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22425 Omit unused local var.
22427 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22428 Don't assume string length fits in int.
22429 (keyremap_step, read_key_sequence): Use size_t for sizes.
22430 (read_key_sequence): Don't check last_real_key_start redundantly.
22432 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22433 instead of alloca (Bug#8344).
22435 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22436 (Fbacktrace_frame): Don't assume nframes fits in int.
22438 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22440 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22443 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22445 * cm.c (calccost): Turn while-do into do-while, for clarity.
22447 * keyboard.c (syms_of_keyboard): Use the same style as later
22448 in this function when indexing through an array. This also
22449 works around GCC bug 48267.
22451 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22453 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22455 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22456 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22458 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22459 This avoids undefined behavior on integer overflow, and is a bit
22460 more convenient anyway since it is compared to a size_t variable.
22462 Variadic C functions now count arguments with size_t, not int.
22463 This avoids an unnecessary limitation on 64-bit machines, which
22464 caused (substring ...) to crash on large vectors (Bug#8344).

22474 * fns.c (concat): Likewise.
22475 * frame.c (x_set_frame_parameters): Likewise.
22476 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22477 0 if not found, not -1. All callers changed.
22479 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22480 (stack_copy_size): Now size_t, not int.
22481 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22483 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22485 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
22486 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22487 All callers changed.
22489 * lisp.h (multibyte_char_to_unibyte):
22490 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22491 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

22502 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22503 don't set the hook to nil, but remove the offending function instead.
22504 (Qcommand_hook_internal): Remove, unused.
22505 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22506 Vcommand_hook_internal.
22508 * eval.c (enum run_hooks_condition): Remove.
22509 (funcall_nil, funcall_not): New functions.
22510 (run_hook_with_args): Call each function through a `funcall' argument.

22524 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
22525 All callers changed.
22527 * w32.c (_wsa_errlist): Use braces for struct initializers.
22529 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

22582 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
22584 * keyboard.c (timer_check): Remove parameter `do_it_now',

22687 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22689 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22690 unconditionally since it does the check itself.
22692 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22694 Fix more problems found by GCC 4.5.2's static checks.
22696 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22697 the first time through the loop, since we know p0 < p1 then.
22698 This also avoids a gcc -Wstrict-overflow warning.
22700 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22701 leading to a memory leak, possible in functions like
22702 load_charset_map_from_file that can allocate an unbounded number
22703 of objects (Bug#8318).
22705 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22706 that could (at least in theory) be that large.
22708 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22709 This is less likely to overflow, and avoids undefined behavior if
22710 overflow does occur. All callers changed. Use strtoul to scan
22711 for the unsigned long integer.
22712 (pint2hrstr): Simplify and tune code slightly.
22713 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

22723 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22726 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22728 * process.c (Fmake_network_process): Use socklen_t, not int,
22729 where POSIX says socklen_t is required in portable programs.
22730 This fixes a porting bug on hosts like 64-bit HP-UX, where
22731 socklen_t is wider than int (Bug#8277).
22732 (Fmake_network_process, server_accept_connection):
22733 (wait_reading_process_output, read_process_output):
22736 * process.c: Rename or move locals to avoid shadowing.

22746 Make tparam.h and terminfo.c consistent.
22747 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22748 Include tparam.h instead, since it declares them.
22749 * cm.h (PC): Remove extern decl; tparam.h now does this.
22750 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22751 * terminfo.c: Include tparam.h, to check interfaces.
22752 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22753 (tparam): Adjust signature to match interface in tparam.h;
22754 this removes some undefined behavior. Check that outstring and len
22755 are zero, which they always are with Emacs.
22756 * tparam.h (PC, BC, UP): New extern decls.
22758 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22759 (xftfont_open): Rename locals to avoid shadowing.

22773 * composite.c (composition_compute_stop_pos): Rename local to
22775 (composition_reseat_it): Remove unused locals.
22776 (find_automatic_composition, composition_adjust_point): Likewise.
22777 (composition_update_it): Mark var as initialized.
22778 (find_automatic_composition): Mark vars as initialized,
22779 with a FIXME (Bug#8290).

22783 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22784 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22785 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22786 to avoid shadowing.
22788 * textprop.c (property_change_between_p): Remove; unused.
22790 * intervals.c (interval_start_pos): Now static.
22792 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

22798 Fix pointer signedness.
22799 (alsa_choose_format): Remove unused local var.
22800 (wav_play): Initialize a variable to 0, to prevent undefined
22801 behavior (Bug#8278).
22803 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22805 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22807 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22808 clobbering (Bug#8298).
22809 * sysdep.c (sys_subshell): Likewise.
22810 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22812 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22813 This should get cleaned up, so that child_setup has the
22814 same signature on all platforms.
22816 * callproc.c (call_process_cleanup): Now static.
22817 (relocate_fd): Rename locals to avoid shadowing.
22819 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22821 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22822 not to be necessary, and produces flickering.
22824 2011-03-20 Glenn Morris <rgm@gnu.org>
22826 * config.in: Remove file.
22828 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

22842 * xfaces.c (Fx_load_color_file):
22843 Read color file from absolute filename (bug#8250).

22858 (sigchld_handler): Now static.
22860 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
22861 That way, the code declares only the vars that it needs.

22871 (CONSTANTLIM): Remove; unused.
22872 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
22873 Define only if needed.
22875 * unexelf.c (unexec): Name an expression,
22876 to avoid gcc -Wbad-function-cast warning.
22877 Use a different way to cause a compilation error if anyone uses
22878 n rather than nn, a way that does not involve shadowing.
22879 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22881 * deps.mk (unexalpha.o): Remove; unused.
22883 New file unexec.h, the (simple) interface for unexec (Bug#8267).

22957 * lisp.h (eassert): Check that the argument compiles, even if
22958 ENABLE_CHECKING is not defined.
22960 * data.c (Findirect_variable): Name an expression, to avoid
22961 gcc -Wbad-function-cast warning.

22973 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
22974 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
22976 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.

22978 (Fmemory_limit): Cast sbrk's returned value to char *.

23004 (RETALLOC_IF): Define only if needed.
23005 (WORDCHAR_P): Likewise. This one is never needed, but is used
23006 only in a comment talking about a compiler bug, so put inside
23007 the #if 0 of that comment.

23035 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23036 New macros, so that the caller can use some names other than
23037 gcpro1, gcpro2, etc.
23038 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23040 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23041 argument, for consistency with GCPRO2_VAR, etc: it is now the
23042 prefix of the variable, not the variable itself. All uses
23044 * dired.c (directory_files_internal, file_name_completion):
23045 Rename locals to avoid shadowing.
23047 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23048 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23049 dired.c's scmp function, had undefined behavior.
23050 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23051 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23052 * buffer.h: ... to here, because these macros use current_buffer,
23053 and the new implementation with inline functions needs to have
23054 current_buffer in scope now, rather than later when the macros
23056 (downcase, upcase1): New static inline functions.
23057 (DOWNCASE, UPCASE1): Reimplement using these functions.
23058 This avoids undefined behavior in expressions like
23059 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23060 from race conditions in accessing the global variables
23061 case_temp1 and case_temp2.
23062 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.

23099 * buffer.c (fix_overlays_before): Mark locals as initialized.
23100 (fix_start_end_in_overlays): Likewise. This function should be
23101 simplified by using pointers-to-pointers, but that's a different

23104 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
23105 (report_overlay_modification): Rename locals to avoid shadowing.

23110 to suppress a gcc -Wclobbered warning that does not seem to be right.
23111 (MAXPATHLEN): Define only if needed.
23113 * process.c (serial_open, serial_configure): Move decls from here ...
23114 * systty.h: ... to here, so that they can be checked.
23116 * fns.c (get_random, seed_random): Move extern decls from here ...
23117 * lisp.h: ... to here, so that they can be checked.
23119 * sysdep.c (reset_io): Now static.
23120 (wait_for_termination_signal): Remove; unused.
23122 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

23126 (DENSE_TABLE_SIZE): Remove; unused.
23127 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
23128 (describe_map_tree):
23129 Rename locals to avoid shadowing.
23131 * keyboard.c: Declare functions static if they are not used elsewhere.

23472 (decode_coding_emacs_mule): Mark variables that gcc
23473 -Wuninitialized does not deduce are never used uninitialized.
23474 (detect_coding_iso_2022): Initialize a local variable that might
23475 be used uninitialized. Leave a FIXME because it's not clear that
23476 this initialization is needed. (Bug#8211)
23477 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
23478 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):
