36 This bug was introduced by my 2013-02-25 change that simplified
37 data_start configuration. Without this change, on GNU/Linux
38 an Emacs configured with --enable-profiling fails immediately
39 due to a profiler signal.

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

121 only to the range checks affected by the 2013-03-24 change.
122 This patch reverts most of the 2013-03-24 change.

251 Use contents slot, not buffer, where appropriate.
252 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
253 to avoid deleted windows. Use contents slot instead of buffer.
254 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:
255 * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c:

471 2013-03-21 Paul Eggert <eggert@cs.ucla.edu>
473 Use functions and constants to manipulate Lisp_Save_Value objects.
474 This replaces code that used macros and strings and token-pasting.
475 The change makes the C source a bit easier to follow,
476 and shrinks the Emacs executable a bit.
477 * alloc.c: Verify some properties of Lisp_Save_Value's representation.
478 (make_save_value): Change 1st arg from string to enum. All callers
481 (mark_object): Use if, not #if, for GC_MARK_STACK.

483 (XSAVE_OBJECT): Now functions, not macros.
484 (STRING_BYTES_BOUND): Now just a macro, not a constant too;
485 the constant was never used.

487 (SAVE_TYPE_INT_INT_INT, SAVE_TYPE_OBJ_OBJ, SAVE_TYPE_OBJ_OBJ_OBJ)
488 (SAVE_TYPE_OBJ_OBJ_OBJ_OBJ, SAVE_TYPE_PTR_INT, SAVE_TYPE_PTR_OBJ)
489 (SAVE_TYPE_PTR_PTR, SAVE_TYPE_PTR_PTR_OBJ, SAVE_TYPE_MEMORY):
491 (struct Lisp_Save_Value): Replace members area, type0, type1, type2,
492 type3 with a single member save_type. All uses changed.
493 (save_type, set_save_pointer, set_save_integer): New functions.
494 * print.c (PRINTX): Remove.

504 (WINDOW_TOTAL_COLS, WINDOW_TOTAL_LINES, WINDOW_LEFT_EDGE_COL)
505 (WINDOW_TOP_EDGE_LINE): Drop Lisp_Object to integer conversion.
506 * dispnew.c, frame.c, w32fns.c, window.c, xdisp.c, xfns.c:
507 Adjust users where appropriate.
509 2013-03-20 Dmitry Antipov <dmantipov@yandex.ru>

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

595 source bytes directly.
596 (produce_chars): Call insert_from_gap with the new arg 0.
597 (encode_coding): Likewise.

622 and incorrect code. Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE
624 (w32fullscreen_hook): If the frame is visible, reset
625 f->want_fullscreen flag after changing the frame size. If the
626 frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
629 2013-03-13 Daniel Colascione <dancol@dancol.org>
631 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
632 too so that these builds can use Cygwin's file conversion
633 functions. (We've been building and linking cygw32.o all along
634 and just not using it.)
636 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
638 File synchronization fixes (Bug#13944).
639 * Makefile.in (LIB_FDATASYNC): New macro.
641 * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
642 * fileio.c (Fwrite_region, write_region_inhibit_fsync):
643 Don't worry about HAVE_FSYNC, since a substitute fsync is
644 available if the system lacks one.

650 activated, call w32fullscreen_hook, to make sure the new frame
651 dimensions are in effect. (Bug#13937)
653 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
655 * xdisp.c (init_iterator): Simplify because both character and byte
656 positions are either specified or -1. Add eassert. Adjust comment.
657 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
658 character and byte positions can be obtained from marker.

678 Include <sys/param.h> unconditionally, as that works elsewhere and
679 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
680 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
683 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>

761 (adjust_after_insert): Call adjust_after_replace with the new arg
764 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
766 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
767 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
768 from Elisp via unread-command-events.
770 * keyboard.c (access_keymap_keyremap): Accept nil return value from
771 functions to mean "no change".
773 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
775 region-cache.c, scroll.c, search.c: Use bool for booleans.
776 * lisp.h (compile_pattern):
777 * scroll.c (do_scrolling, do_direct_scrolling):
778 * search.c (struct regexp_cache, compile_pattern_1)
779 (compile_pattern, string_match_1, search_command)
780 (trivial_regexp_p, search_buffer, Freplace_match, match_limit)
781 (search_regs_saved, Fregexp_quote):
782 Use bool for boolean.
783 * region-cache.c (region_cache_forward, region_cache_backward):

786 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
788 * search.c (find_newline): Accept start and end byte positions
789 as arguments and allow -1 if not known.

795 Adjust call to find_newline.
796 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

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

906 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
907 * sysdep.c (list_system_processes)
908 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
909 Make it a stub in this case; otherwise the build might fail,
910 and this code hasn't been tested on such hosts anyway.
911 Problem reported by Nelson H. F. Beebe in
912 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
913 and analyzed by Jérémie Courrèges-Anglas in
914 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
916 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
918 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
919 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
920 (get_visually_first_element, move_it_vertically_backward): Ajust users.
921 * bidi.c (bidi_find_paragraph_start): Likewise.
922 * indent.c (vmotion): Likewise.
924 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
926 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
927 * filelock.c: Include <c-ctype.h>.
928 (MAX_LFINFO): New top-level constant.
929 (lock_info_type): Remove members pid, boot_time. Add members at,
930 dot, colon. Change user member to be the entire buffer, not a
931 pointer. This allows us to handle the case where a foreign
932 pid or boot time exceeds the local range. All uses changed.
933 (LINKS_MIGHT_NOT_WORK): New constant.
934 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
935 (defined_WINDOWSNT): Remove.
936 (MAKE_LOCK_NAME, file_in_lock_file_name):
937 Always use .#FILE (not .#-FILE) for the file lock,
938 even if it is a regular file.
939 (rename_lock_file): New function.
940 (create_lock_file): Use it.
941 (create_lock_file, read_lock_data):
942 Prefer a symbolic link for the lock file, falling back on a
943 regular file if symlinks don't work. Do not try to create
944 symlinks on MS-Windows, due to security hassles. Stick with
945 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
946 link, rename, unlink, mkstemp) when creating locks, as a GNUish
947 host may be using a Windowsish file system, and cannot use
948 MS-Windows-only system calls. Fall back on mktemp if mkstemp
949 doesn't work. Don't fail merely because of a symlink-contents
950 length limit in the current file system; fall back on regular
951 files. Increase the symlink contents length limit to 8 KiB, this
952 should be big enough for any real use and doesn't crunch the
954 (create_lock_file, lock_file_1, read_lock_data):
955 Simplify allocation of lock file buffers now that they fit in 8 KiB.
956 (lock_file_1): Return error number, not bool. All callers changed.
957 (ELOOP): New macro, if not already defined.
958 (read_lock_data): Return size of lock file contents, not Lisp object.
959 All callers changed. Handle a race condition if some other process
960 replaces a regular-file lock with a symlink lock or vice versa,
961 while we're trying to read the lock.
962 (current_lock_owner): Parse contents more carefully, to help avoid
963 confusing a regular-file lock with some other application's use
964 of the file. Check for lock file contents being too long, or
965 not parsing correctly.
966 (current_lock_owner, lock_file):
967 Allow foreign pid and boot times that exceed the local range.
968 (current_lock_owner, lock_if_free, lock_file):
969 Simplify allocation of lock file contents.
970 * w32.c (sys_rename_replace): New function, containing most of
971 the contents of the old sys_rename.
972 (sys_rename): Use it.
973 (fchmod): New dummy function.
974 * w32.h (sys_rename_replace, fchmod): New decls.
976 2013-03-05 Eli Zaretskii <eliz@gnu.org>
978 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
979 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
980 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
981 <dmantipov@yandex.ru>.
983 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
985 * composite.c (get_composition_id, fill_gstring_header):
986 Use make_uninit_vector where appropriate.
987 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
988 * xselect.c (clean_local_selection_data): Likewise.
990 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
992 Fix misuse of ImageMagick that caused core dump (Bug#13846).
993 * image.c (imagemagick_load_image): Calculate height and width
994 after flattening the image, not before.
996 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
998 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
999 * ftfont.c (ftfont_shape_by_flt): Likewise.
1000 * w32uniscribe.c (uniscribe_shape): Likewise.
1002 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1004 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1005 The old approach, which fell back on DIR/.#FILE.0 through
1006 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1007 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1008 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1009 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1010 because the locking mechanism was never reliable in that case).
1011 This patch fixes this and other bugs discovered by a code
1012 inspection that was prompted by
1013 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1014 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1015 to avoid interoperability problems between the MS-Windows and
1016 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1017 instances of Emacs now ignore each others' locks.
1018 * filelock.c (defined_WINDOWSNT): New constant.
1019 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1020 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1021 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1022 regular files on MS-Windows hosts.
1023 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1024 Use SAFE_ALLOCA to avoid problems with long file names.
1025 (MAX_LFINFO): Now a local constant, not a global macro.
1026 (IS_LOCK_FILE): Remove.
1027 (lock_file_1): Don't inspect errno if symlink call succeeds;
1028 that's not portable.
1029 (lock_file): Document that this function can return if lock
1031 (lock_file): Don't access freed storage.
1033 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
1035 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
1037 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1039 * textprop.c: Use bool for booleans.
1040 (validate_interval_range, Fadd_text_properties)
1041 (Fremove_text_properties): Prefer bool to int when either works.
1043 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1045 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1046 If the interval tree changes as a side effect of calling
1047 modify_region, re-do processing starting from the call to
1048 validate_interval_range. (Bug#13743)
1050 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1052 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1055 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1057 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1058 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1059 access to the lock file until it is written and closed.
1062 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1064 * callint.c (Qcall_interactively):
1065 * macros.c (Qexecute_kbd_macro):
1068 2013-02-26 Bastien Guerry <bzg@gnu.org>
1070 * window.c (Frecenter): Tiny docstring enhancement.
1072 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1074 Minor textprop integer cleanup.
1075 * intervals.h, textprop.c (add_text_properties_from_list):
1076 Return void, not int, since nobody uses the return value.
1077 * textprop.c (validate_plist, add_properties, remove_properties)
1078 (Fadd_text_properties):
1079 Don't assume list length fits in int.
1080 (interval_has_all_properties, interval_has_some_properties)
1081 (interval_has_some_properties_list, add_properties, remove_properties)
1082 (Fadd_text_properties, Fremove_text_properties)
1083 (Fremove_list_of_text_properties, text_property_stickiness):
1084 Use bool for booleans.
1085 (Fadd_text_properties, Fremove_text_properties):
1086 (Fremove_list_of_text_properties):
1087 Reindent do-while as per GNU style.
1089 2013-02-25 Eli Zaretskii <eliz@gnu.org>
1091 Implement CLASH_DETECTION for MS-Windows.
1093 * filelock.c [WINDOWSNT]: Include w32.h.
1094 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1095 function of that name. Up-case the macro arguments.
1096 (IS_LOCK_FILE): New macro.
1097 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1098 (create_lock_file): New function, with body extracted from
1100 [WINDOWSNT]: Implement lock files by writing a regular file with
1101 the lock information as its contents.
1102 (read_lock_data): New function, on Posix platforms just calls
1104 [WINDOWSNT]: Read the lock info from the file.
1105 (current_lock_owner): Call read_lock_data instead of calling
1106 emacs_readlinkat directly.
1107 (lock_file) [WINDOWSNT]: Run the file name through
1110 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1111 just check if the process by that PID exists.
1113 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1114 also present, as doing so will fail to error out if the file
1117 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1119 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1120 (Fremove_list_of_text_properties): Skip all of the intervals in
1121 the region between START and END that already have resp. don't
1122 have the requested properties, not just the first one.
1123 Add assertions that the loop afterwards always modifies the
1124 properties. (Bug#13743)
1126 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1128 * callint.c (Fcall_interactively): Use the right lexical environment

1135 This is a followon simplification to the fix for Bug#13650.
1136 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
1137 (START_FILES): Remove. All uses removed.
1138 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
1139 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
1140 (buildobj.h): Use it.
1141 ($(ALLOBJS)): Depend on globals.h.
1142 (temacs$(EXEEXT)): Use $(ALLOBJS).
1143 * autodeps.mk (ALLOBJS): Move to Makefile.in.
1144 * deps.mk (vm-limit.o):
1145 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
1146 Do not depend on mem-limits.h.
1147 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
1148 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
1149 [__GNUC__ && !ORDINARY_LINK]: Remove.

1153 (make_hdr): Use DATA_START instead of start_of_data.
1154 * vm-limit.c: Move most of mem-limits.h's contents here.
1155 (data_start): New decl. It's OK if this is approximate,
1156 so simplify-away some unnecessary exactness.
1157 (POINTER): Remove; all uses removed.
1158 (data_space_start): Now char *, to avoid casts.
1159 (exceeds_lisp_ptr): New function, replacing the old
1160 EXCEEDS_LISP_PTR macro. All uses changed.
1161 (check_memory_limits): Simplify and remove casts.
1162 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

1167 * xdisp.c (set_message): Only check for debug-on-message if STRING
1168 is a string. (Bug#13797)
1170 2013-02-24 Paul Eggert <eggert@cs.ucla.edu>
1172 Fix regression introduced by July 10 filelock.c patch.
1173 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
1174 2012-07-10 patch to this file. Reported by Eli Zaretskii in
1175 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
1176 and diagnosed by Andreas Schwab in
1177 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.

1181 Assume C89 or better.
1182 * ralloc.c (SIZE, POINTER, NIL):
1183 * vm-limit.c (POINTER):
1184 Remove, replacing all uses with C89 equivalents. These old
1185 symbols were present only for porting to pre-C89 platforms.
1187 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1189 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.

1205 2013-02-19 Daniel Colascione <dancol@dancol.org>
1207 * sheap.c (report_sheap_usage): Use message, not message1, so
1208 that we don't try to create a buffer while we're in the middle
1209 of dumping Emacs. Explain why.
1211 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
1213 * search.c (find_newline): Return byte position in bytepos.

1224 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
1226 2013-02-19 Eli Zaretskii <eliz@gnu.org>
1228 * w32proc.c (new_child): Avoid leaking handles if the subprocess
1229 resources were not orderly released.
1231 2013-02-17 Eli Zaretskii <eliz@gnu.org>
1233 * xdisp.c (x_draw_vertical_border): For a window that is neither
1234 the leftmost nor the rightmost, redraw both the left and the right
1235 vertical borders. (Bug#13723)

1257 * w32.c (sys_chown): Remove unused function.
1259 * w32term.c <input_signal_count>: Declare 'volatile'
1260 unconditionally. (Bug#9066)
1262 * w32.c (set_errno): Reset h_errno and don't set it to any other
1263 value. Set errno instead.
1264 (check_errno): Reset h_errno.
1265 (sys_socket, socket_to_fd, sys_bind, sys_connect)
1266 (sys_gethostname, sys_getservbyname, sys_getpeername)
1267 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
1268 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set

1278 * keyboard.c (read_char): Fix calculation of auto-save time out
1279 when auto-save-timeout is less than 4. (Bug#13720)
1281 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
1282 time. Improve diagnostics in DebPrint. (Bug#13546)

1288 make sure errno is set to an appropriate value. (Bug#13546)
1289 (socket_to_fd): Add assertion against indexing fd_info[] with a
1290 value that is out of bounds.
1291 (sys_accept): If fd is negative, do not set up the child_process
1292 structure for reading.
1294 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
1296 * composite.c (fill_gstring_header): Remove useless prototype.

1308 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1310 Fix AIX port (Bug#13650).
1311 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1312 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1313 was #undeffed earlier, so it cannot be used as a macro here.
1314 Use the constant and not the macro.
1316 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1318 * w32proc.c (new_child): If no vacant slots are found in
1319 child_procs[], make another pass looking for slots whose process
1320 has exited or died. (Bug#13546)
1322 * w32.c (sys_pipe): When failing due to file descriptors above
1323 MAXDESC, set errno to EMFILE.
1324 (_sys_read_ahead): Update cp->status when failing to read serial
1325 communications input, so that the status doesn't stay at
1326 STATUS_READ_IN_PROGRESS. (Bug#13546)
1328 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1330 * gtkutil.c (tb_size_cb): New function.
1331 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
1333 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1335 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
1338 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
1340 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1342 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

1345 and break long line.
1346 * font.h (font_range): Adjust prototype.
1347 * composite.c (autocmp_chars): Pass byte position to font_range.
1348 Break long line. Remove useless prototype and format comment.
1350 2013-02-13 Glenn Morris <rgm@gnu.org>
1352 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1354 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1356 Improve AIX port some more (Bug#13650).
1357 With this, it should be as good as it was in 23.3, though it's
1358 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1359 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1360 * unexaix.c (start_of_text): Remove.
1361 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1362 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1363 (orig_load_scnptr, orig_data_scnptr):
1364 Now off_t, not long, since they are file offsets.
1365 (make_hdr): Use _data, not start_of_data ().
1366 This is the key part of the fix.
1367 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1368 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1370 * pre-crt0.c (data_start): Initialize to 1.
1371 This ports to compilers that optimize the external declaration
1372 'int x = 0;' as if it were 'int x;' to shrink the executable.
1374 Improve AIX port (Bug#13650).
1375 This doesn't fix the bug, but it makes progress: Emacs builds now.
1376 * unexaix.c: Include inttypes.h, stdarg.h.
1377 (report_error, report_error_1): Mark as _Noreturn.
1378 (report_error): Don't report the wrong errno.
1379 (report_error_1): Now varargs. All callers changed.
1380 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1381 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1382 (write_ptr): Use %p to print address rather than %lx and a cast
1383 to unsigned long. Grow buffer a bit, to be safer.
1385 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1387 * bidi.c (bidi_resolve_neutral): After finding the next
1388 non-neutral character, accept NEUTRAL_ON type as well, because
1389 directional control characters, such as LRE and RLE, have their
1390 type converted to that by bidi_resolve_weak. This avoids aborts
1391 when LRE/RLE follows a run of neutrals.
1392 (bidi_move_to_visually_next): Assert that return value of
1393 bidi_peek_at_next_level is non-negative. Negative values will
1396 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1398 Minor getenv-related fixes.
1399 * callproc.c (Fcall_process_region) [!DOS_NT]:

1413 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1415 (display_line): Set w->region_showing to the value of
1416 it->region_beg_charpos, not to -1. This fixes redisplay
1417 optimization when cursor is moved up after M->. (Bug#13623)
1419 (try_scrolling): Scroll text up more if point is too close to ZV
1420 and inside the scroll margin. This makes sure point is moved
1421 outside the scroll margin in these cases.
1423 * window.h (struct window): region_showing can no longer be
1426 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>

1433 Use memchr and memrchr rather than scanning byte-by-byte.
1434 * search.c (find_newline): Rename from scan_buffer.
1435 Omit first arg TARGET, as it's always '\n'. All callers changed.
1437 Clean up read_key_sequence a tiny bit more.

1439 (read_key_sequence): Remove unused locals.
1441 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1443 Clean up read_key_sequence a bit; reread active keymaps after first event.

1448 (active_maps): New function.
1449 (test_undefined): Also return true for nil bindings.
1450 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1451 a single (composed) keymap. Remember `first_event' to choose the right
1452 set of active keymaps. Recompute the set of keymaps after receiving
1453 the first event. Remove GOBBLE_FIRST_EVENT.
1454 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1455 * keyboard.h (read_char): Update declaration.
1456 * lread.c (read_filtered_event): Adjust call to read_char.
1458 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1460 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1461 Don't use the limitation on backwards movement when lines are truncated
1462 in the window. (Bug#13675)
1464 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1466 * marker.c (set_marker_internal): If desired position is passed
1467 as a marker, avoid call to buf_charpos_to_bytepos.
1468 * window.c (Fset_window_point): Omit redundant type checking.
1469 (Fset_window_start): Likewise. Format comment.
1470 (window_scroll_pixel_based): Use set_marker_restricted_both
1471 with character and byte positions obtained from an iterator.
1472 (Fset_window_configuration): Use set_marker_restricted_both.
1473 * xdisp.c (message_dolog): Likewise.
1475 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1477 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1478 When text lines are longer than window's screen lines, don't move back
1479 too far. This speeds up some redisplay operations. (Bug#13675)
1481 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1483 * syntax.c (scan_sexps_forward): Fix byte position calculation

1494 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1495 (sxhash_float): Return EMACS_UINT, for consistency with the other
1497 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1498 non-static inline function and therefore can't use static vars.
1499 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1500 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1501 with the other hash functions.
1503 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1505 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1506 XXXXXX part of the temporary file pattern is not downcased even
1507 when w32-downcase-file-names is non-nil. (Bug#13661)
1509 * xdisp.c (decode_mode_spec): Remove handling of %t.
1511 * msdos.c (careadlinkatcwd): Remove.
1513 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1515 * lread.c (skip_dyn_bytes): New function (bug#12598).

1551 argument is known to be a vector.
1552 * fns.c (Flocale_info): Likewise for ASET.
1553 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1554 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1556 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1558 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1561 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
1562 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and

1566 (ns_last_use_native_fullscreen): New variable.
1567 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
1568 (x_set_window_size): Do not take title bar and tool bar into account
1569 if isFullscreen returns YES.
1570 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1571 (check_native_fs): New function.
1572 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
1573 (ns_term_init): Remove NEW_STYLE_FS.

1575 and tool bar if isFullscreen returns NO.
1576 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
1577 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
1578 with HAVE_NATIVE_FS.

1588 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1589 (syms_of_nsterm): Add ns-use-native-fullscreen.
1591 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1593 * fileio.c (Qchoose_write_coding_system): Now static.
1595 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1597 * xdisp.c (window_buffer_changed): region_showing can be negative,
1598 which still means region is being displayed.
1599 (redisplay_internal): Resurrect code that forced redisplay of the
1600 whole window when showing region and the mark has changed.
1601 Record the new mark position to allow redisplay optimizations.
1602 (display_line): If it->region_beg_charpos is non-zero, set the
1603 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1605 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1606 not bitfield of 1 bit.
1608 2013-02-03 Daniel Colascione <dancol@dancol.org>
1610 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1611 daemon mode works on cygw32 when Emacs is installed and not just
1614 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1616 Avoid file time stamp bug on MS-Windows (Bug#13149).
1617 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1618 as FAT32 doesn't update time stamps when truncating them.
1619 Also, check that a file time stamp is not a multiple of 100 ns;
1620 this should catch all instances of the problem on MS-Windows,
1621 as its native file system resolution is 100 ns or worse, and
1622 checking for a non-multiple of 100 ns should impose only a small
1623 overhead on systems with ns resolution.
1625 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1627 Avoid encoding file names on MS-Windows when they need to be run
1628 through dostounix_filename.
1629 * w32.c (normalize_filename): Accept an additional argument
1630 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1631 downcase it even if w32-downcase-file-names is non-nil.
1632 (dostounix_filename): Accept an additional argument MULTIBYTE and
1633 pass it to normalize_filename.
1634 (emacs_root_dir): Adjust.
1636 * msdos.h (dostounix_filename): Adjust prototype.
1638 * w32.h (dostounix_filename): Adjust prototype.
1640 * msdos.c (dostounix_filename): Accept an additional argument and
1642 (init_environment): Adjust callers of dostounix_filename.
1644 * fileio.c (Ffile_name_directory, file_name_as_directory)
1645 (directory_file_name, Fexpand_file_name)
1646 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1648 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1650 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1651 variables, as egetenv is case-insensitive for DOS_NT.
1653 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1654 with an encoded file name.
1656 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1657 Adjust calls to dostounix_filename.
1659 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1661 * unexw32.c (unexec): Adjust call to dostounix_filename.
1663 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1665 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1668 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1671 * callproc.c (Fcall_process): Make sure program name in PATH and
1672 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1673 is passed to exec/spawnve, which fails unless the file-name
1676 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1677 even if w32-quote-process-args is nil.
1679 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1681 Fix timestamp bug when write-region appends nothing (Bug#13149).
1682 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1683 the file's time stamp doesn't change if Emacs happens to write nothing
1684 to the file, and on a buggy file system this could cause Emacs to
1685 incorrectly infer that the file system doesn't have the bug.
1686 Avoid this problem by inhibiting the inference in this case.
1688 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1690 * window.h (struct window): Convert base_line_number, base_line_pos
1691 and column_number_displayed members from Lisp_Object to ptrdiff_t.

1695 (make_window): Initialize column_number_displayed.
1696 * print.c (print_object): Follow the printed representation of
1697 frames and print window pointer to distinguish between windows.

1701 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1702 (try_scrolling, try_cursor_movement, redisplay_window)
1703 (try_window_reusing_current_matrix, try_window_id, display_line)
1704 (display_mode_lines, decode_mode_spec): Adjust users.
1705 * .gdbinit (pwinx): Do not print sequence_number.
1707 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1709 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1710 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1711 * dired.c: Include <fcntl.h>.
1712 (open_directory): New function, which uses open and fdopendir
1713 rather than opendir. DOS_NT platforms still use opendir, though.

1715 (file_attributes): New function, with most of the old Ffile_attributes.
1716 (directory_files_internal, Ffile_attributes): Use it.
1717 (file_attributes, file_name_completion_stat): First arg is now fd,
1718 not dir name. All uses changed. Use fstatat rather than lstat +
1720 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1721 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1722 (emacs_readlinkat): New function, with much of the old
1723 Ffile_symlink_p, but with an fd argument for speed.
1724 It uses readlinkat rather than careadlinkatcwd, so that it
1725 need not assume the working directory.
1726 (Ffile_symlink_p): Use it.
1727 * filelock.c (current_lock_owner): Use emacs_readlinkat
1728 rather than emacs_readlink.
1729 * lisp.h (emacs_readlinkat): New decl.
1730 (READLINK_BUFSIZE, emacs_readlink): Remove.
1731 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1732 (emacs_norealloc_allocator, emacs_readlink): Remove.
1733 This stuff is moved to fileio.c.
1734 * w32.c (fstatat, readlinkat): New functions.
1735 (careadlinkat): Don't check that fd == AT_FDCWD.
1736 (careadlinkatcwd): Remove; no longer needed.

1748 (sys_close): Zero out the flags for the file descriptor before
1749 closing it. (Bug#13546)
1751 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1752 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1753 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1756 * w32.c (w32_get_long_filename, init_environment, readlink):
1757 Support file names encoded in DBCS codepages.
1758 (readlink): Use the current file-name-coding-system, not the ANSI
1759 codepage, to decode and handle targets of symlinks.
1761 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1763 * w32.c (opendir): Now accepts a 'const char *'.
1765 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>

1769 * dispnew.c (preemption_period, preemption_next_check): Remove.
1770 (Vredisplay_preemption_period): Likewise.
1771 (update_frame, update_single_window, update_window, update_frame_1):
1772 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1773 used, following the 2012-06-22 change.
1775 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1777 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1779 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1781 * font.c (num_fonts): Remove the leftover from old
1782 debugging code. Adjust comment style here and there.
1783 * insdel.c (insert_1): Remove.
1784 * lisp.h (insert_1): Remove prototype.
1785 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1787 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1789 * w32.c (max_filename_mbslen): New function.
1790 (normalize_filename, readdir): Use it to detect locales where ANSI
1791 encoding of file names uses a double-byte character set (DBCS).
1792 If a DBCS encoding is used, advance by characters using
1793 CharNextExA, instead of incrementing a 'char *' pointer.
1794 Use _mbslwr instead of _strlwr. (Bug#13515)
1796 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1797 request of memory reservation to 1.7GB. (Bug#13065)

1807 Avoid redundant calls to strlen.
1809 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1811 Drop async_visible and async_iconified fields of struct frame.
1812 This is possible because async input is gone; for details, see
1813 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1814 * frame.h (struct frame): Remove async_visible and async_iconified
1815 members, convert garbaged to unsigned bitfield. Adjust comments.
1816 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1817 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1818 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:

1820 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1822 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1823 properly. Likewise for obscured.

1833 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1835 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1837 * xdisp.c (message2, message2_nolog): Remove functions.
1838 (message3, message3_nolog): Extract nbytes and multibyteness directly
1839 from the string. Change all callers.
1840 (message3_nolog): Don't set message_enable_multibyte since set_message
1841 will reset it anyway.
1842 (message1, message1_nolog): Use message3.
1843 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1844 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1845 (set_message): Drop all but the second arg, which has to be a string.
1846 (set_message_1): Simplify now that we know that a1 is NULL and the
1847 second arg is a string.
1848 * frame.h (struct frame): Remove `message_buf' field.
1849 Use glyphs_initialized_p instead.
1850 (FRAME_MESSAGE_BUF): Remove macro.

1852 * lisp.h (message2, message2_nolog): Remove declarations.
1853 (message3, message3_nolog): Update declarations.
1854 * keyboard.c (read_char_minibuf_menu_text)
1855 (read_char_minibuf_menu_width): Remove vars.
1856 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1857 to correctly handle multibyte strings.
1858 * frame.c (delete_frame): Don't free message_buf any more.
1859 * editfns.c (message_text, message_length): Remove vars.
1860 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1861 * fileio.c (auto_save_error): Use message3 instead of message2.
1862 * dispnew.c (adjust_frame_message_buffer): Remove function.
1864 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1866 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1867 real estate used for the tool bar and the menu bar.
1869 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1871 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1872 hidden buffer is prepared to modification (Bug#13164).
1874 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1876 * window.h (struct window): Change window_end_valid member from
1877 Lisp_Object to a bitfield. Adjust comments.
1878 (wset_window_end_valid): Remove.
1879 * window.c (adjust_window_count): Clear window_end_valid.
1880 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1881 (Fwindow_line_height, set_window_buffer, Frecenter)
1882 (Fsplit_window_internal, Fdelete_other_windows_internal)
1883 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1884 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1885 * xdisp.c (check_window_end, reconsider_clip_changes)
1886 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1887 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1888 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1890 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1892 * xdisp.c (mark_window_display_accurate): Simplify the loop
1893 assuming that the only one of vchild, hchild or buffer window
1894 slots is non-nil. Call mark_window_display_accurate_1 for
1895 the leaf windows only.
1896 (mark_window_display_accurate_1): Always assume leaf window.
1899 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1901 * emacs.c (Qkill_emacs_hook): Now static.
1903 * fileio.c (Finsert_file_contents): Simplify.
1904 Remove unnecessary assignments and tests.
1906 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1908 * w32.c (acl_set_file): Don't test for errors unless
1909 set_file_security returns FALSE. Avoids spurious errors when
1912 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1914 * fileio.c (Finsert_file_contents): Revert code introduced at
1915 2013-01-18 in favor of the simpler and generally better fix.
1916 Save stack space by removing 'buffer' and reusing 'read_buf'
1919 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1921 * lisp.h (eabs): Define unconditionally (Bug#13419).
1922 The old "#if !defined (eabs)" was an unnecessary revenant of back
1923 when this macro was called "abs". Document 'eabs' better.
1925 2013-01-19 Glenn Morris <rgm@gnu.org>
1927 * fns.c (Frandom): Doc fix.
1929 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1931 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1932 segfault when there are lots of overlays.
1934 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1935 when there are lots of overlays.
1936 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1937 for the details and a way to reproduce.
1939 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1941 * fileio.c: Use O_APPEND to append.
1942 This corresponds better to the natural interpretation of "append",
1943 and avoids the need to open the output file twice, or to invoke
1944 lseek when APPEND is neither nil nor a number.
1945 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1946 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1947 file possibly twice, and lseeking to its end; this avoids the
1948 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1949 at the same time: the combination is never needed and apparently
1950 it doesn't work with DOS_NT.
1952 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1953 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1955 Allow floating-point file offsets.
1956 Problem reported by Vitalie Spinu in
1957 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1958 * fileio.c (emacs_lseek): Remove.
1959 (file_offset): New function.
1960 (Finsert_file_contents, Fwrite_region): Use it.
1962 2013-01-19 Chong Yidong <cyd@gnu.org>
1964 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1965 aborting on Fsignal (Bug#13289).
1967 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1969 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1970 set_file_security as failure due to insufficient privileges.
1971 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1972 (fstat): Return owner and group like 'stat' and 'lstat' do.
1974 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1976 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1977 The bug was observed on Ubuntu operating inside a virtual machine,
1978 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1979 The workaround introduces a race condition on non-buggy hosts,
1980 but it's an unlikely race and anyway there's a nearly identical
1981 nearby race that can't be fixed.
1982 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1984 (Fwrite_region): Test for file system time stamp bug.
1985 (init_fileio): New function.
1986 * lisp.h (init_fileio): Declare it.
1987 * emacs.c (main): Call it.
1989 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1990 and make it more consistent with other stat-failure diagnostics.
1992 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1994 Fix crash when inserting data from non-regular files.
1995 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1996 for the error description produced by valgrind.
1997 * fileio.c (read_non_regular): Rename to read_contents.
1998 Free Lisp_Save_Value object used to pass parameters.
1999 (read_non_regular_quit): Rename to read_contents_quit.
2000 (Finsert_file_contents): Redesign internal file reading loop to adjust
2001 gap and end positions after each read and so help make_gap to work
2002 properly. Do not signal an I/O error too early and so do not leave
2003 not yet decoded characters in a buffer, which was the reason of
2004 redisplay crash. Use list2 to build return value. Adjust comments.
2006 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2008 Close a race when statting and reading files (Bug#13149).
2009 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2010 This avoids a race if the file is renamed between stat and open.
2011 This race is not the problem originally noted in Bug#13149;
2012 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2014 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

2021 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2022 * alloc.c (format_save_value): Rename to make_save_value.
2023 (make_save_pointer): New function.
2024 (record_xmalloc): Use make_save_pointer.
2025 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2026 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2027 Change users of make_save_value to make_save_pointer.

2041 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2043 * keymap.c (map_keymap_internal): Use format_save_value.
2044 (map_keymap_char_table_item): Adjust accordingly.
2045 * fileio.c (non_regular_fd, non_regular_inserted)
2046 (non_regular_nbytes): Remove.
2047 (Finsert_file_contents): Convert trytry to ptrdiff_t.
2048 Use format_save_value to pass parameters to read_non_regular.
2049 (read_non_regular): Use XSAVE_ macros to extract parameters.
2051 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
2053 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
2055 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2057 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2058 extraction from any Lisp_Save_Value slot. Add type checking.
2059 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
2060 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
2061 * xselect.c: All users changed.
2063 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

2071 object with the specified internal structure.
2072 (make_save_value): Reimplement using format_save_value.
2073 * editfns.c (save_excursion_save): Use format_save_value.
2074 (save_excursion_restore): Use XSAVE_OBJECT.
2076 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
2078 Avoid needless casts with XSAVE_POINTER.
2079 * alloc.c (mark_object) [GC_MARK_STACK]:
2080 * dired.c (directory_files_internal_unwind):
2081 * fileio.c (do_auto_save_unwind):
2082 * gtkutil.c (pop_down_dialog):
2083 * keymap.c (map_keymap_char_table_item):
2084 * lread.c (load_unwind):
2085 * nsmenu.m (pop_down_menu):
2086 * print.c (print_object) [GC_MARK_STACK]:
2087 * xfns.c (clean_up_file_dialog):
2088 * xmenu.c (cleanup_widget_value_tree):
2089 Omit casts between XSAVE_POINTER and a pointer type.
2091 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2093 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
2094 * eval.c (eval_sub): Protect `form' from being GCed before its
2095 car and cdr becomes protected with the backtrace entry.
2097 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2099 Make Lisp_Save_Value more versatile storage for up to four objects.
2100 * lisp.h (toplevel): Enumeration to describe types of saved objects.
2101 (struct Lisp_Save_Value): New layout. Adjust comments.

2109 (free_save_value): Likewise.
2110 (mark_object): Likewise.
2111 * editfns.c (save_excursion_save): Pack everything within
2112 Lisp_Save_Value and so avoid xmalloc.
2113 (save_excursion_restore): Adjust to match new layout. Use free_misc
2114 because we do not allocate extra memory any more. Add eassert.
2115 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2116 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

2126 Bug#11484 with LCD smoothing on.
2128 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
2130 Fix SIGDANGER handlers, for AIX (Bug#13408).
2131 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
2132 Move handlers here from emacs.c; they were out of place.
2134 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
2136 * xterm.c (syms_of_xterm): Adjust documentation for
2137 scroll-bar-adjust-thumb-portion.

2142 determine whether scroll bar thumb size should be adjusted or
2143 not. Use variable for MOTIF.
2145 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for

2157 (nsfont_open): Move block_input earlier. Add unblock_input before early
2159 (nsfont_draw): Add block/unblock_input calls.
2161 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
2163 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
2164 for old_charpos and old_bytepos.
2166 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>
2168 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
2169 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
2170 Clear tzvalbuf_in_environ if this workaround is in effect.
2171 Problem and fix reported by Kazuhiro Ito.
2173 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>

2182 string cross-reference(s).
2184 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
2186 Avoid unnecessary byte position calculation for the gap movement.
2187 Since all users of move_gap do CHAR_TO_BYTE for other purposes
2188 anyway, all of them should use move_gap_both instead.
2189 * lisp.h (move_gap): Remove prototype.
2190 * insdel.c (move_gap): Remove.
2191 (move_gap_both): Add eassert.

2200 * term.c (init_tty): Use them instead of rolling our own code.
2201 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
2202 switches from 'signal' to 'pthread_sigmask', which is safer in
2203 multithreaded applications.
2204 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
2205 which has already arranged for that.
2206 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
2207 This is the main part of the bug fix.

2216 Omit buffer_slot_type_mismatch and use generic predicates to enforce
2217 the type of per-buffer values where appropriate.
2218 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
2219 predicate, which is how it's really used now. Adjust comment.
2220 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
2221 * buffer.c (buffer_slot_type_mismatch): Remove.
2222 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

2226 left-margin-width, right-margin-width, left-fringe-width,
2227 right-fringe-width, scroll-bar-width and buffer-display-count.
2228 Use Qstringp for default-directory, buffer-file-name,
2229 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
2230 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
2232 * data.c (store_symval_forwarding): Adjust to call the predicate.
2234 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
2236 * w32.c (get_name_and_id, acl_set_file):
2237 * w32term.c (w32fullscreen_hook): Remove unused local variables.

2247 * insdel.c (make_gap_larger): Use GAP_BYTES_DFL. Adjust comment.
2248 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
2249 (make_gap_1): New function to adjust the gap of any buffer.
2250 * coding.c (coding_alloc_by_making_gap): Use it.
2251 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
2252 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
2254 2013-01-08 Juri Linkov <juri@jurta.org>
2256 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
2257 of (supports :underline (:style wave)). (Bug#13000)

2273 (echo_char): Use it.
2274 (read_key_sequence): When echoing mock input, ensure that the
2275 trailing dash is properly added.
2277 2013-01-05 Eli Zaretskii <eliz@gnu.org>
2279 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
2280 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
2281 digits for buffer positions, before misalignment starts.
2282 Display "0" for integer "object" field.
2283 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2284 Display the newline glyph more unambiguously.
2286 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2288 * nsterm.m (ns_draw_underwave):
2289 * w32term.c (w32_draw_underwave):
2290 * xterm.c (x_draw_underwave): Make underwave look more triangular

2294 * w32term.c (x_draw_glyph_string):
2295 * xterm.c (x_draw_glyph_string): Don't use previous underline
2296 thickness and position if previous underline type is underwave.

2316 * term.c (tty_ins_del_lines):
2317 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2318 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2320 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2322 * w32.c (unsetenv): Set up the string passed to _putenv
2324 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
2325 for the bug this caused.
2327 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
2329 * coding.c (Qmac): Now static.
2331 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2333 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
2334 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
2335 handlebox_widget. Set toolbar_in_hbox to false/true, set
2336 toolbar_is_packed to true.
2337 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
2338 (update_frame_tool_bar): Check toolbar_is_packed for packing.
2339 Show all on TOOLBAR_TOP_WIDGET.
2340 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
2341 by TOOLBAR_TOP_WIDGET.
2342 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
2343 Check toolbar_is_packed.
2344 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
2345 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2346 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
2348 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2349 (xg_update_menubar): Update title only if
2350 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2351 (xg_update_submenu): Skip tearoff only if
2352 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2353 (xg_initialize): Initialize xg_detached_menus only if
2354 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2356 * xterm.h (struct x_output): Surround handlebox_widget with
2357 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2358 toolbar_in_hbox is bool.
2360 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2362 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2363 (LIBS_GNUSTEP): Define.
2364 (LIBES): Add $(LIBS_GNUSTEP).
2365 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
2367 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2369 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2370 continuation glyph on a TTY with an indication of an empty line.
2373 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2375 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2376 file's SELinux context or ACLs successfully set, nil otherwise.
2378 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
2380 * w32proc.c (reader_thread): Avoid passing NULL handles to
2381 SetEvent and WaitForSingleObject.
2383 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2385 Port EXTERNALLY_VISIBLE to Clang 3.2.
2386 * conf_post.h (__has_attribute): New macro.
2387 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2389 2012-12-27 Glenn Morris <rgm@gnu.org>
2391 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2392 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2394 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2396 * fileio.c (file_name_as_directory, directory_file_name):
2397 Accept an additional argument MULTIBYTE to indicate whether the input C
2398 came from a multibyte or a unibyte Lisp string; all callers
2399 adjusted. Don't assume the input string is always multibyte.
2401 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2402 don't ENCODE_FILE them, and return a unibyte string if the input
2404 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2405 don't assume the input strings will always be multibyte. If the
2406 input strings are multibyte, decode strings obtained from C
2409 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2411 * lisp.h (toplevel): Add two notices to the comment about
2412 defining a new Lisp data type.
2413 * print.c (print_object): If Lisp_Save_Value object's pointer
2414 is the address of a memory area containing Lisp_Objects, try
2416 * alloc.c (valid_lisp_object_p): Adjust comment.
2418 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2420 * keyboard.c (record_asynch_buffer_change): Initialize an event
2421 only if it's really needed.
2422 * frame.h (enum output_method): Remove output_mac member since
2423 it's a leftover from the deleted code.
2424 * frame.c (Fframep): Adjust user here ...
2425 * terminal.c (Fterminal_live_p): ... and here.
2426 * coding.c (Qmac): Now here because it's only used to denote
2427 end-of-line encoding type.
2428 (syms_of_coding): DEFSYM it.
2429 * frame.h (Qmac): Remove duplicated declaration.
2431 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2433 * window.c (select_window_1): Now static, since it's used only here.
2435 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2437 * window.c (window_body_cols): Subtract display margins from the
2438 window body width on TTYs as well. See
2439 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2440 for the original report.
2442 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2444 * xdisp.c (redisplay_window): Remove inner local variable
2445 because the outer shadowed one has the same meaning.
2446 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2448 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2449 (xg_create_tool_bar): Adjust users.
2451 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2453 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2454 * buffer.c (Fget_buffer_create): Use it to set compact field of
2455 struct buffer_text to avoid accessing an uninitialized value
2456 when compact_buffer is called for the first time.
2457 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2458 (Fset_buffer_modified_p): Use buffer_window_count to check
2459 whether the buffer is displayed in some window.
2460 * xdisp.c (message_dolog): Likewise.
2462 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2464 * w32.c (acl_set_file): If setting the file security descriptor
2465 fails, and the new DACL is identical to the existing one, silently
2466 return success. This fixes problems for users backing up their
2467 own files without having the necessary privileges for setting
2468 security descriptors.
2470 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2472 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2473 after WaitForSingleObject returns normally. This expedites reader
2474 thread shutdown when delete_child triggers it.
2475 (reap_subprocess): More accurate commentary for why we call
2476 delete_child only when cp->fd is negative.
2478 * w32.c (sys_close): Do not call delete_child on a subprocess
2479 whose handle is not yet closed. Instead, set its file descriptor
2480 to a negative value, so that reap_subprocess will call
2481 delete_child on that subprocess when its SIGCHLD arrives.
2482 This avoids closing handles used for communications between sys_select
2483 and reader_thread, which doesn't give sys_select a chance to
2484 notice that the process exited and invoke the SIGCHLD handler for
2487 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2489 * nsfns.m (Fns_do_applescript): Run event loop until script has
2490 been executed (Bug#12969).
2491 (ns_run_ascript): Chech as_script for nil, set to nil after
2494 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2496 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2498 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2500 * w32term.c (w32fullscreen_hook): New function.
2501 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2503 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2505 * fileio.c (Finsert_file_contents): Doc fix.
2507 * w32proc.c (new_child, delete_child, find_child_pid): For a
2508 subprocess, consider its slot being in use as long as its process
2509 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2510 slot when a new process is started immediately after killing
2511 another one, without waiting enough time for the first process to
2512 be reaped and resources allocated for it be orderly freed.
2514 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2516 2012-12-21 Chong Yidong <cyd@gnu.org>
2518 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2520 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2522 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2524 * w32.c (get_name_and_id): Always pass NULL as the first argument
2525 of lookup_account_sid. Avoids crashes with UNC file names that
2526 refer to DFS domains, not to specific machine names. (Bug#12621)
2527 Remove now unused argument FNAME; all callers changed.
2528 (get_file_owner_and_group): Remove now unused argument FNAME; all
2531 2012-12-21 Chong Yidong <cyd@gnu.org>
2533 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2534 error for invalid chars, don't check for a nil return value.
2536 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2538 Avoid calls to CHAR_TO_BYTE if byte position is known.
2539 * editfns.c (make_buffer_string_both): Use move_gap_both.
2540 (Fbuffer_string): Use make_buffer_string_both.
2541 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2543 (buf_bytepos_to_charpos): Likewise.
2544 (charpos_to_bytepos): Remove.
2545 * fileio.c (Finsert_file_contents): Use move_gap_both.
2546 * search.c (Freplace_match): Likewise.
2547 * process.c (process_send_region): Likewise. Use convenient
2548 names for byte positions.
2549 * lisp.h (charpos_to_bytepos): Remove prototype.
2550 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2551 * insdel.c (move_gap): Likewise.
2553 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2555 * xdisp.c (redisplay_internal): Remove now-unused local.
2557 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2559 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2560 (redisplay_internal): Don't bother selecting the frame to get the
2561 proper value of frame-local variables (bug#13225).
2563 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2565 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2566 Rename 4th argument since it may be buffer or string. Adjust comment.
2567 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2569 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2571 * coding.c (Fdetect_coding_region): Do not check start and end with
2572 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2573 (code_convert_region): Likewise.
2575 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2577 * w32.c (acl_get_file, acl_set_file): Run the file name through
2578 map_w32_filename, and resolve any symlinks in the file name, like
2580 (acl_set_file): Call revert_to_self, if any privileges were
2583 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2585 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2586 ($(BLD)/w32.$(O)): Update dependencies.
2588 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2590 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2591 propagate redisplay's scrolling (if any) to the right window.
2592 (redisplay_internal): Use ensure_selected_frame.
2593 (display_mode_lines): Complete last fix.
2594 * window.c (select_window_1): New func, extracted from select_window.
2595 (select_window): Use it.
2596 * window.h (select_window_1): Declare.
2598 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2600 Emulate Posix ACL APIs on MS-Windows.
2601 * w32.c: Include sddl.h and sys/acl.h.
2602 (SDDL_REVISION_1): Define if not already defined.
2603 (g_b_init_get_security_descriptor_dacl)
2604 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
2605 (g_b_init_is_valid_security_descriptor)
2606 (g_b_init_set_file_security): New static flags.
2607 (globals_of_w32): Initialize them to zero.
2608 (SetFileSecurity_Name): New string constant.

2612 (IsValidSecurityDescriptor_Proc): New typedefs.
2613 (get_file_security, get_security_descriptor_owner)
2614 (get_security_descriptor_group): Set errno to ENOTSUP.

2617 (convert_sddl_to_sd, acl_valid, acl_to_text, acl_from_text)
2618 (acl_free, acl_get_file, acl_set_file): New functions.
2620 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
2622 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2624 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2625 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2626 for some of that bug's symptoms can now cause Emacs to abort.
2627 Remove the workaround.
2628 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2629 The bug that caused SIGCHLD to get lost has been fixed, and the
2630 workaround for it can now cause Emacs to abort.
2632 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2634 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2635 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2636 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
2638 2012-12-16 Romain Francoise <romain@orebokech.com>
2640 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2641 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2642 and copy ACL entries of file in addition to SELinux context if set.
2643 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2645 * Makefile.in (LIBACL_LIBS): New macro.
2648 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
2650 * fileio.c (internal_delete_file): Use bool for boolean.
2652 2012-12-15 Eli Zaretskii <eliz@gnu.org>
2654 Fix bug #13079 on MS-Windows with temp files not being deleted.

2657 (register_child): First argument is now pid_t.
2658 (record_infile, record_pending_deletion): New prototypes.
2660 * w32proc.c (new_child): Initialize input_file and
2661 pending_deletion members of the child.
2662 (delete_child): Delete the child's temporary input file, if any,
2663 that is pending deletion.
2664 (register_child): First argument is now pid_t.
2665 (record_infile, record_pending_deletion): New functions.
2666 (reap_subprocess): Fix a typo in DebPrint string.
2667 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2669 * fileio.c (internal_delete_file): Return an int again: non-zero
2670 if delete-file succeeds, zero otherwise.
2672 * lisp.h (internal_delete_file): Adjust prototype.
2674 * callproc.c (Fcall_process): Don't overwrite infile with result
2676 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2677 asynchronous subprocess, record the name of the input file name,
2679 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2680 delete the file, record it as pending deletion when the subprocess
2683 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2685 * editfns.c [HAVE_PWD_H]: Include grp.h.
2687 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
2689 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
2691 Fix permissions bugs with setgid directories etc. (Bug#13125)
2692 * dired.c (Ffile_attributes): Return t as the 9th attribute,
2693 to mark it as a placeholder. The old value was often wrong.
2694 The only user of this attribute has been changed to use
2695 file-ownership-preserved-p instead, with its new group arg.
2696 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
2698 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
2700 * xdisp.c (select_frame_for_redisplay, display_mode_lines):
2701 Keep selected_window and selected_frame in sync.
2703 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2705 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2706 try to get accurate owner and group information from NT file
2707 security APIs. This is to make most callers of 'stat' and
2708 'lstat', which don't need that information, much faster.
2710 * dired.c (Ffile_attributes) [WINDOWSNT]:
2711 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2712 owner and group information from 'lstat'.
2714 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2716 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2717 as that confuses set-auto-coding, so insist on the head-read
2718 returning the full 1024 bytes. Let lseek compute the tail offset;
2719 less work for us. Do not ignore I/O errors when reading the tail.
2721 * xdisp.c: Minor style fixes.
2722 (init_iterator): Hoist assignment out of if-expression.
2723 (markpos_of_region): Callers now test for sign, not for -1.
2725 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
2727 Minor redisplay optimization when the region length is zero.
2728 * xdisp.c (markpos_of_region): New function.
2729 (init_iterator): Do not highlight the region of zero length.
2730 (redisplay_window): Check whether the region is of non-zero length.
2731 (try_cursor_movement): Allow if the region length is zero.
2732 (try_window_reusing_current_matrix, try_window_id): Likewise.
2734 2012-12-13 Eli Zaretskii <eliz@gnu.org>
2736 * search.c (search_buffer): Check the inverse translations of each
2737 character in pattern when the buffer being searched is unibyte.
2740 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2742 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2743 files, fixing a regression from 24.2.
2744 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2746 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2748 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2749 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2750 Remove unnecessary S_ISLNK test, as (contra the comments) this
2751 function can't copy symlinks. Improve quality of error message
2752 when attempting to copy files that are neither regular files nor
2755 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
2757 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.
2758 * gtkutil.c (xg_set_toolkit_scroll_bar_thumb):
2759 * window.c (Frecenter):
2760 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
2761 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
2763 2012-12-12 Daniel Colascione <dancol@dancol.org>
2765 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2766 the dumped Emacs is not a sparse file, greatly improving Cygwin
2767 "make bootstrap" performance.
2769 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
2771 * inotify.c (inotify_callback): Generate an Emacs event for every
2772 incoming inotify event.
2774 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2776 * xdisp.c (handle_face_prop): Fix logic of computing
2777 it->start_of_box_run_p.

2985 * dbusbind.c (Fdbus_init_bus):
2987 * xterm.c (x_term_init):

2998 no longer needed here.

3001 (set_time_zone_rule): Maintain the TZ=value string separately.
3002 (syms_of_editfns): Don't initialize initial_tz;
3003 init_editfns now does it.
3004 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
3005 * lisp.h (xputenv): New decl.
3007 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

3022 Simplify get_lim_data.
3023 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3024 Remove USG and vlimit methods; no longer used these days.
3025 Add #error catchall just in case.
3027 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3028 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3029 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.

3051 This will cause a production Emacs to dump core instead of
3054 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3056 * frame.c (make_frame): Do not set window's buffer to t.
3057 * window.c (Fsplit_window_internal): Likewise. Previously it was
3058 used to indicate that the window is being set up. Now we use
3059 set_window_buffer for all new windows, so the condition in ...
3060 (Fset_window_buffer): ... is always true and can be removed.
3062 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3064 Convenient macro to check whether the buffer is hidden.
3065 * buffer.h (BUFFER_HIDDEN_P): New macro.

3072 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
3073 if the child process is still running. Instead, exit the wait
3074 loop and return zero. (Bug#13086)

3078 * frame.h (x_char_width, x_char_height): Remove prototypes.

3089 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
3091 Fix a recently-introduced delete-process race condition.
3092 * callproc.c, process.h (record_kill_process):
3093 New function, containing part of the old call_process_kill.
3094 (call_process_kill): Use it.
3095 This does not change call_process_kill's behavior.
3096 * process.c (Fdelete_process): Use record_kill_process to fix a
3097 race condition that could cause Emacs to lose track of a child.
3099 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3101 Avoid code duplication between prev_frame and next_frame.
3102 * frame.c (candidate_frame): New function. Add comment.
3103 (prev_frame, next_frame): Use it. Adjust comment.
3105 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3107 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3108 fails, signal an error instead of continuing with an empty
3110 Encode expanded temp file pattern before passing it to mkstemp or
3113 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3114 Encode the file name before passing it to dostounix_filename, in
3115 case it will downcase it (under w32-downcase-file-names).
3118 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3120 Minor call-process cleanups.
3121 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3122 at the same time as other platforms, to simplify analysis.
3123 No need for fd0_volatile since we have synch_process_fd.
3124 Avoid needless emacs_close; arg is always negative.
3126 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3128 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous

3133 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3134 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer

3140 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3141 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3142 members to a bitfields.
3144 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3146 Don't let call-process be a zombie factory (Bug#12980).
3147 Fixing this bug required some cleanup of the signal-handling code.
3148 As a side effect, this change also fixes a longstanding rare race
3149 condition whereby Emacs could mistakenly kill unrelated processes,
3150 and it fixes a bug where a second C-g does not kill a recalcitrant
3151 synchronous process in GNU/Linux and similar platforms.
3152 The patch should also fix the last vestiges of Bug#9488,
3153 a bug which has mostly been fixed on the trunk by other changes.
3154 * callproc.c, process.h (synch_process_alive, synch_process_death)
3155 (synch_process_termsig, sync_process_retcode):
3156 Remove. All uses removed, to simplify analysis and so that
3157 less consing is done inside critical sections.
3158 * callproc.c (call_process_exited): Remove. All uses replaced
3159 with !synch_process_pid.
3160 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3161 These take the role of what used to be in unwind-protect arg.
3163 (block_child_signal, unblock_child_signal):
3164 New functions, to avoid races that could kill innocent-victim processes.
3165 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3166 (call_process_kill): Record killed processes as deleted, so that
3167 zombies do not clutter up the system. Do this inside a critical
3168 section, to avoid a race that would allow the clutter.
3169 (call_process_cleanup): Fix code so that the second C-g works again
3170 on common platforms such as GNU/Linux.
3171 (Fcall_process): Create the child process in a critical section,
3172 to fix a race condition. If creating an asynchronous process,
3173 record it as deleted so that zombies do not clutter up the system.
3174 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3175 light of these changes. Omit unnecessary call to emacs_close
3176 before failure, as the unwind-protect code does that.
3177 * callproc.c (call_process_cleanup):
3178 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3179 * process.c (record_deleted_pid): New function, containing
3180 code refactored out of Fdelete_process.
3181 (Fdelete_process): Use it.
3182 (process_status_retrieved): Remove. All callers changed to use
3183 child_status_change.
3184 (record_child_status_change): Remove, folding its contents into ...
3185 (handle_child_signal): ... this signal handler. Now, this
3186 function is purely a handler for SIGCHLD, and is not called after
3187 a synchronous waitpid returns; the synchronous code is moved to
3188 wait_for_termination. There is no need to worry about reaping
3189 more than one child now.
3190 * sysdep.c (get_child_status, child_status_changed): New functions.
3191 (wait_for_termination): Now takes int * status and bool
3192 interruptible arguments, too. Do not record child status change;
3193 that's now the caller's responsibility. All callers changed.
3194 Reimplement in terms of get_child_status.
3195 (wait_for_termination_1, interruptible_wait_for_termination):
3196 Remove. All callers changed to use wait_for_termination.
3197 * syswait.h: Include <stdbool.h>, for bool.
3198 (record_child_status_change, interruptible_wait_for_termination):
3200 (record_deleted_pid, child_status_changed): New decls.
3201 (wait_for_termination): Adjust to API changes noted above.
3203 * bytecode.c, lisp.h (Qbytecode): Remove.
3204 No longer needed after 2012-11-20 interactive-p changes.
3206 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3208 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3209 the scroll margin, move point outside the margin. (Bug#13055)
3211 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3213 * gtkutil.c (my_log_handler): New function.
3214 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3216 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3218 * lisp.h (modify_region): Rename to...
3219 (modify_region_1): ...new prototype.
3220 * textprop.c (modify_region): Now static. Adjust users.
3221 * insdel.c (modify_region): Rename to...
3222 (modify_region_1): ...new function to work with current buffer.
3223 Adjust comment and users. Use true and false for booleans.
3225 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3227 * alloc.c (free_save_value): New function.
3228 (safe_alloca_unwind): Use it.
3229 * lisp.h (free_save_value): New prototype.
3230 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3232 (save_excursion_restore): Adjust to match saved data structure.
3233 Use free_save_value to offload some work from GC. Drop obsolete
3236 2012-12-03 Chong Yidong <cyd@gnu.org>
3238 * fileio.c (Vauto_save_list_file_name): Doc fix.
3240 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3242 * w32fns.c: Remove prototype of atof.
3243 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3245 (file_dialog_callback): Make it UINT_PTR.
3247 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3250 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3251 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already

3260 Fix xpalloc confusion after memory is exhausted.
3261 * alloc.c (xpalloc): Comment fix.
3262 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3263 and signals an error, do not clear charset_table_size, as
3264 charset_table is still valid.
3265 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3267 Use execve to avoid need to munge environ (Bug#13054).
3268 * callproc.c (Fcall_process):
3269 * process.c (create_process):
3270 Don't save and restore environ; no longer needed.
3271 * callproc.c (child_setup):
3272 Use execve, not execvp, to preserve environ.
3274 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3276 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3278 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3280 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3281 display for sliced images (Bug#10500).
3283 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3285 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3287 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3288 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3290 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3292 * xdisp.c (window_outdated): Remove eassert since it hits
3293 some suspicious corner cases (see Bug#13007 and Bug#13012).
3294 (mode_line_update_needed): New function.
3295 (redisplay_internal, redisplay_window): Use it.
3296 (ensure_selected_frame): New function.
3297 (redisplay_internal, unwind_redisplay): Use it.
3298 (redisplay_internal): Move comment about buffer_shared...
3299 (buffer_shared_and_changed): ...near to its real use.
3301 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3303 * callproc.c (Fcall_process): Don't misreport vfork failure.
3305 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3307 * callproc.c (Fcall_process): Fix vfork portability problems.
3308 Do not assume that fd[0], count, filefd, and save_environ survive
3309 vfork. Fix bug whereby wrong errno value could be reported for
3310 pipe failure. Some minor cleanups, too, as follows. Move buf and
3311 bufsize to the context where they're needed. Change new_argv to
3312 be of type char **, as this is more convenient and avoids casts.
3313 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3314 Now local constants, not macros.
3316 2012-11-18 Kenichi Handa <handa@gnu.org>
3318 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3319 for the variable "f".
3321 2012-11-13 Kenichi Handa <handa@gnu.org>
3323 * font.c (font_unparse_xlfd): Exclude special characters from the
3324 generating XLFD name.
3326 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

3329 * dired.c (stat_uname, stat_gname):
3330 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
3332 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

3341 Assume EIO and EAGAIN are defined.
3342 * unexcoff.c (write_segment): Assume EFAULT is defined.
3344 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3346 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.

3351 violations when repeatedly clicking on the "Top" link of the
3352 "bread-crumbs" in Info buffers.

3362 were always defined.
3364 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3366 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3367 between bpos_covered and bpos_max. This fixes cursor display when
3368 several display strings follow each other.
3370 * .gdbinit (pgx): If the glyph's object is a string, display the
3371 pointer to string data, rather than the value of the string object
3372 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3374 * indent.c (Fvertical_motion): If the starting position is covered
3375 by a display string, return to one position before that, to avoid
3376 overshooting it inside move_it_to. (Bug#12930)
3378 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3380 * frame.h (struct frame): Remove display_preempted member
3381 since all users are dead long ago.

3383 * w32menu.c (pending_menu_activation): Remove since not
3385 (set_frame_menubar): Adjust user.
3386 * w32term.h (struct x_output): Drop outdated #if 0 code.
3387 (struct w32_output): Use bitfields for explicit_parent,
3388 asked_for_visible and menubar_active members.
3389 Drop unused pending_menu_activation member.
3390 * xterm.h (struct x_output): Drop outdated #if 0 code.
3391 Use bitfields for explicit_parent, asked_for_visible,
3392 has_been_visible and net_wm_state_hidden_seen members.
3394 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3396 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3397 of a literal "/". (Bug#12955)
3398 (gl-stamp): Invoke fc.exe directly, not through cmd.
3400 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
3402 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
3403 * dired.c: Assume HAVE_DIRENT_H.
3404 (NAMLEN): Remove, replacing with ...
3405 (dirent_namelen): New function. All uses changed. Use the GNU macro
3406 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3407 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3408 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3409 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3411 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3412 * ndir.h: Rename to ../nt/inc/dirent.h.
3413 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3414 Do not include <dirent.h>; no longer needed.
3415 * w32.c: Include <dirent.h> rather than "ndir.h".
3417 2012-11-23 Chong Yidong <cyd@gnu.org>
3419 * xftfont.c (xftfont_open): Remove duplicate assignment.
3421 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3423 * alloc.c (Fgarbage_collect): Unblock input after clearing
3424 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3425 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3426 * msdos.c (IT_frame_up_to_date): Use it here...
3427 * w32term.c (w32_frame_up_to_date): ...here...
3428 * xterm.c (XTframe_up_to_date): ...and here...
3429 * nsterm.m (ns_frame_up_to_date): ...but not here.
3430 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3432 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3433 Do not check whether GC is in progress.
3435 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3437 * xdisp.c (window_buffer_changed): New function.
3438 (update_menu_bar, update_tool_bar): Use it to
3439 simplify large 'if' statements.
3440 (redisplay_internal): Generalize commonly used
3441 'tail' and 'frame' local variables.
3443 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3445 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3446 with Windows system header.
3448 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3450 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3451 * alloc.c: Assume unistd.h exists.
3452 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
3453 * sysdep.c (get_current_dir_name): Assume getcwd exists.
3454 (getwd) [USG]: Remove; no longer needed.
3455 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3456 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3457 * w32.h (getcwd): Remove decl.
3459 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
3461 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
3462 Make it set selected_window as well.
3463 (update_tool_bar): Use it.
3465 2012-11-21 Ken Brown <kbrown@cornell.edu>
3467 * emacs.c (main): Set the G_SLICE environment variable for all
3468 Cygwin builds, not just GTK builds. See
3469 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3471 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3473 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3474 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3475 Define for the MSVC compiler.
3477 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3479 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3480 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3481 dostounix_filename. Prevents crashes down the road, because
3482 dostounix_filename assumes it gets a unibyte string.
3483 Reported by Michel de Ruiter <michel@sentient.nl>, see
3484 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html

3494 Test NILP rather than Qunbound.
3495 (Ffmakunbound): Set to Qnil.
3496 (Fsymbol_function): Never signal an error.
3497 (Finteractive_form): Ignore Qunbound.
3499 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3501 * eval.c (interactive_p): Remove no-longer-used decl.
3503 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3505 * xdisp.c (buffer_shared): Adjust comment.
3506 (buffer_shared_and_changed): New function.
3507 (prepare_menu_bars, redisplay_internal): Use it to
3508 decide whether all windows or frames should be updated.
3509 (window_outdated): New function.
3510 (text_outside_line_unchanged_p, redisplay_window): Use it.
3511 (redisplay_internal): Likewise. Fix indentation.
3513 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3515 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3516 (syms_of_eval): Remove corresponding defsubr.
3517 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3519 2012-11-19 Daniel Colascione <dancol@dancol.org>
3521 * w32fns.c (Fx_file_dialog):
3522 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3523 cygwin_convert_file_name*.
3525 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3526 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3528 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3530 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3532 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3534 * w32select.c: Include w32common.h before w32term.h, so that
3535 windows.h gets included before w32term.h uses some of its
3536 features, see below.
3538 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3540 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3542 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3544 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3546 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3547 (ns_select): Return at once if events are held (Bug#12834).
3549 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3551 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3552 Needed following 2012-10-20 change. (Bug#12902)
3554 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3556 * w32proc.c (waitpid): Remove unused label get_result.
3558 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3560 * makefile.w32-in (SYSWAIT_H): New macro.
3561 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3562 ($(BLD)/sysdep.$(O)): Update dependencies.
3564 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3566 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3567 * callproc.c (relocate_fd): Assume F_DUPFD.
3568 * emacs.c, term.c (O_RDWR): Remove.
3569 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3570 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3571 * nsterm.m: Assume <fcntl.h> exists.
3572 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3573 (create_pty, Fmake_network_process, server_accept_connection)
3574 (wait_reading_process_output, init_process_emacs):
3576 (wait_reading_process_output): Put in a special case for WINDOWSNT
3577 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3578 It's not clear this is needed, but it's a more-conservative change.
3579 (create_process): Assume FD_CLOEXEC.
3580 (create_process, create_pty): Assume O_NOCTTY.
3581 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3582 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3583 Omit if not DOS_NT, since F_GETFL is not defined there.
3584 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3585 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3587 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3588 lack it, since gnulib guarantees this.
3589 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3591 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3593 * w32.c (faccessat): Pretend that directories have the execute bit
3594 set. Emacs expects that, e.g., in files.el:cd-absolute.
3596 * w32proc.c (create_child): Don't clip the PID of the child
3597 process to fit into an Emacs integer, as this is no longer a
3599 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3600 reaping only the process specified by PID argument, if that is
3601 positive. Use PID instead of dead_child to know which process to
3602 reap. Wait for the child to die only if WNOHANG is not in
3604 (sys_select): Don't set dead_child.
3606 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3607 as it is no longer needed.
3609 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3611 (record_child_status_change): Remove the setting of
3612 record_at_most_one_child for the !WNOHANG case.
3614 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3616 Fix problems in ns port found by static checking.
3617 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3618 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3619 not to process group.
3620 (ns_select): Use emacs_write, not write, as that's more robust
3621 in the presence of signals.
3622 (fd_handler:): Check for read errors.
3624 2012-11-16 Glenn Morris <rgm@gnu.org>
3626 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3628 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3630 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3632 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3634 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3635 use the same value of thread handle.
3636 (start_timer_thread): If the timer thread exited (due to error),
3637 clean up by closing the two handles it used. Duplicate the caller
3638 thread's handle here, so it gets duplicated only once, when
3639 launching the timer thread. Set priority of the timer thread, not
3641 (getitimer): Don't duplicate the caller thread's handle here.
3644 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3646 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3649 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3651 Remove no-longer-used pty_max_bytes variable.
3652 * process.c (pty_max_bytes): Remove; unused.
3653 (send_process): Do not set it.
3655 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3657 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3658 Update dependencies.
3660 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3662 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3663 This follows up on the 2012-09-29 patch that removed indirection
3664 for the 'function' field. Reported by Sergey Vinokurov in
3665 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3667 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3669 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3670 different name, as the MS runtime does not have such a function,
3671 and probably never will.) All callers changed. Ignore DIRFD
3672 value if PATH is an absolute file name, to match Posix spec
3673 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3676 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3678 * xdisp.c (echo_area_display, redisplay_internal):
3679 Omit redundant check whether frame_garbaged is set.
3681 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3683 Use faccessat, not access, when checking file permissions (Bug#12632).
3684 This fixes a bug that has been present in Emacs since its creation.
3685 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3686 which must set some sort of record. (Torek's bug report was against
3687 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3688 same common flaw.) See Torek's Usenet posting
3689 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3690 Posted: Fri Apr 8 14:18:56 1983.

3706 * fileio.c (check_existing, check_executable, check_writable)
3708 Use symbolic names instead of integers for the flags, as they're
3710 (check_writable): New arg AMODE. All uses changed.
3711 Set errno on failure.
3712 (Ffile_readable_p): Use faccessat, not stat + open + close.
3713 (Ffile_writable_p): No need to call check_existing + check_writable.
3714 Just call check_writable and then look at errno. This saves a syscall.
3715 dir should never be nil; replace an unnecessary runtime check
3716 with an eassert. When checking the parent directory of a nonexistent
3717 file, check that the directory is searchable as well as writable, as
3718 we can't create files in unsearchable directories.
3719 (file_directory_p): New function, which uses 'stat' on most platforms
3720 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3721 (Ffile_directory_p, Fset_file_times): Use it.
3722 (file_accessible_directory_p): New function, which uses a single
3723 syscall for efficiency.
3724 (Ffile_accessible_directory_p): Use it.
3725 * xrdb.c (file_p): Use file_directory_p.
3726 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3727 * lread.c (openp): When opening a file, use fstat rather than
3728 stat, as that avoids a permissions race. When not opening a file,
3729 use file_directory_p rather than stat.
3730 (dir_warning): First arg is now a usage string, not a format.
3731 Use errno. All uses changed.
3732 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3733 that merely introduced a race.
3734 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3735 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3736 and similarly for the other O_* flags.
3737 * w32.c (sys_faccessat): Rename from sys_access and switch to
3738 faccessat's API. All uses changed.
3739 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3740 (magic_db): Rename from magic_file_p.
3741 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3742 char *, so that we don't have to test for file existence
3743 separately from opening the file for reading. This removes a race
3744 fixes a permission-checking problem, and simplifies the code.
3746 (file_p): Remove; no longer needed.
3748 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3750 Omit glyphs initialization at startup.

3756 * xdisp.c (clear_garbaged_frames): Likewise.
3758 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3760 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3761 passed to pint2str and pint2hrstr to be at most the size of the
3762 frame's decode_mode_spec_buffer. This avoids crashes with very
3763 large values of FIELD_WIDTH argument to decode_mode_spec.
3766 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3768 Fix a race with verify-visited-file-modtime (Bug#12863).
3769 Since at least 1991 Emacs has ignored an mtime difference of no
3770 more than one second, but my guess is that this was to work around
3771 file system bugs that were fixed long ago. Since the race is
3772 causing problems now, let's remove that code.
3773 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3774 whose time stamp is off by no more than a second. Insist that the
3775 file time stamps match exactly.
3777 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3779 * frame.h (struct frame): Convert external_tool_bar member to
3780 1-bit unsigned bitfield.

3782 all users are long dead. Adjust comment on mouse_position_hook.
3784 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3786 Simplify by using FOR_EACH_FRAME here and there.
3787 * frame.c (next_frame, prev_frame, other_visible_frames)
3788 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3789 * w32term.c (x_window_to_scroll_bar): Likewise.
3790 * window.c (window_list): Likewise.
3791 * xdisp.c (x_consider_frame_title): Likewise.
3792 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3793 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3794 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3795 * xmenu.c (menubar_id_to_frame): Likewise.
3796 * xselect.c (frame_for_x_selection): Likewise.
3797 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3798 (x_window_to_menu_bar): Likewise.
3799 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3801 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3803 * data.c (Qdefalias_fset_function): Now static.
3805 Another tweak to vectorlike_header change.
3806 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3807 Remove, and replace all uses with ...
3808 (next_in_free_list, set_next_in_free_list):
3809 New functions, which respect C's aliasing rules better.
3811 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3813 * window.c (list4i): Rename from 'quad'. All uses changed.
3814 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3816 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3818 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3819 warning about mixing declarations and code in ISO C90.
3821 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3823 * window.c (Fsplit_window_internal): Set combination limit of
3824 new parent window to t iff Vwindow_combination_limit is t;
3825 fixing a regression introduced with the change from 2012-09-22.
3826 (Fset_window_combination_limit): Fix doc-string.
3828 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3830 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3831 amount when the scroll margins are too large. When scrolling
3832 backwards in the buffer, give up if cannot reach point or the
3833 scroll margin within a reasonable number of screen lines.
3834 Fixes point position in window under scroll-up/down-aggressively when
3835 point is positioned many lines beyond the window top/bottom.
3838 * ralloc.c (relinquish): If real_morecore fails to return memory
3839 to the system, don't crash; instead, leave the last heap
3840 unchanged and return. (Bug#12774)
3842 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3844 * lisp.h (AUTOLOADP): New macro.

3849 (Finteractive_form): Simplify.
3850 (Fquo): Don't insist on having at least 2 arguments.
3851 (Qdefalias_fset_function): New var.
3853 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3855 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
3857 * nsfont.m (Qcondensed, Qexpanded): New variables.

3859 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3861 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3863 Fix recently introduced crash on MS-Windows (Bug#12839).
3864 * w32term.h (struct scroll_bar): Use convenient header.
3865 (SCROLL_BAR_VEC_SIZE): Remove.
3866 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3868 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3870 Tweak last vectorlike_header change.
3871 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3872 vectorlike object on the free list. This is introduced to avoid
3873 some (but not all) pointer casting and aliasing problems, see
3874 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3875 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3877 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3879 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3881 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3882 been removed, so remove them here also.
3884 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3886 * doc.c (Fdocumentation): Handle new property
3887 dynamic-docstring-function to replace the old ad-advice-info.
3889 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3891 * fns.c (Qeql, hashtest_eq): Now static.
3893 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3895 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3896 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3897 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

3907 special hash function containing a comparison that always yields 1.
3909 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3911 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3912 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3913 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3916 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3918 * image.c (xpm_make_color_table_h): Fix compiler error because
3919 make_hash_table changed.

3923 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3925 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3927 Use ad-hoc comparison function for the profiler's hash-tables.
3928 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3929 (make_log): Use them.
3930 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3931 call Fequal any more.

3941 (hash_lookup, hash_remove_from_table): Move assertion checking of
3942 hashfn result here. Check hash-equality before calling cmpfn.

3979 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3980 (Fmake_bool_vector): Likewise.
3981 (struct large_vector): New type to represent allocation unit for
3982 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3983 (large_vectors): Change type to struct large_vector.
3984 (allocate_vector_from_block): Simplify.
3985 (PSEUDOVECTOR_NBYTES): Replace with...

4007 * keyboard.c (event_to_kboard): Do not dereference
4008 frame_or_window field of SELECTION_REQUEST_EVENT
4009 and SELECTION_CLEAR_EVENT events (Bug#12814).

4012 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4014 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4015 such as Scroll Lock, if the respective keys are treated as
4016 function keys, not as modifiers. This avoids destroying non-ASCII
4017 keyboard input when Scroll Lock is toggled ON. (Bug#12806)

4021 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4023 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4025 Restore some duplicate definitions (Bug#12814).
4026 This undoes part of the 2012-11-03 changes. Some people build
4027 with plain -g rather than with -g3, and they need the duplicate
4028 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4029 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):

4034 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4035 to keypad keys (Bug#12816).
4037 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4039 Minor adjustments of recently-changed frame functions.
4040 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4041 known to be a frame (we're in the FRAMEP branch).
4042 * lisp.h (Qframep): Remove decl. frame.h declares this.
4043 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4044 since they're meant for Lisp fixnum values.
4046 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4048 * window.c (Fwindow_combination_limit): Revert to the only
4049 required argument and adjust docstring as suggested in
4050 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4051 by Martin Rudalics <rudalics@gmx.at>.

4104 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4105 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4106 file descriptor 2 for standard error. (Bug#12805)
4108 2012-11-05 Chong Yidong <cyd@gnu.org>
4110 * process.c (wait_reading_process_output): Revert previous change.
4112 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4114 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4115 This removes code that has been obsolete since around 1990.
4116 * callproc.c (Fcall_process):
4118 * process.c (create_process):
4119 * term.c (dissociate_if_controlling_tty):

4132 (setsid, tcgetpgrp): New functions.
4134 Simplify by assuming __fpending.
4135 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4136 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4137 Do not assume that __fpending's result fits in int.
4139 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4141 Remove EMACS_OUTQSIZE+sleep hack.
4142 * dispnew.c (update_frame_1): Remove hack for terminals slower
4143 than 2400 bps, which throttled Emacs by having it sleep.
4144 This code hasn't worked since at least 2007, when the multi-tty stuff
4145 was added, and anyway those old terminals are long dead.
4146 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4147 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4149 Fix data-loss with --version (Bug#9574).
4150 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4151 as we can't assume that emacs_strerror is initialized, and strerror
4152 is good enough here.
4153 (main): Invoke atexit earlier, to catch earlier instances of
4154 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4156 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4158 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4159 (keyDown): Remap keypad keys to X11 virtual key codes.
4161 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4163 Fix data-loss with --batch (Bug#9574).
4164 * emacs.c: Include <close-stream.h>.
4165 (close_output_streams): New function.
4166 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4167 and handles errors appropriately.
4168 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4171 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4172 The symptom is a diagnostic "GLib-WARNING **: In call to
4173 g_spawn_sync(), exit status of a child process was requested but
4174 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4175 waitpid(), so exit status can't be returned." The diagnostic
4176 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4177 The real bug is a race condition between Emacs and glib: Emacs
4178 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4179 so that glib can't find it. Work around the bug by invoking
4180 waitpid only on subprocesses that Emacs itself creates.
4181 * process.c (create_process, record_child_status_change):
4182 Don't use special value -1 in pid field, as the caller now must
4183 know the pid rather than having the callee infer it.
4184 The inference was sometimes incorrect anyway, due to another race.
4185 (create_process): Set new 'alive' member if child is created.
4186 (process_status_retrieved): New function.
4187 (record_child_status_change): Use it.
4188 Accept negative 1st argument, which means to wait for the
4189 processes that Emacs already knows about. Move special-case code
4190 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4191 processes that have already been waited for, by testing and
4192 clearing new 'alive' member.
4193 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4194 now does this internally.
4195 (handle_child_signal): Let record_child_status_change do all
4196 the work, since we do not want to reap all exited child processes,
4197 only the child processes that Emacs itself created.
4198 * process.h (Lisp_Process): New boolean member 'alive'.
4200 Omit duplicate definitions no longer needed with gcc -g3.
4201 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4202 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4203 Define only as macros. There's no longer any need to also define
4204 these symbols as enums or as constants, since we now assume
4205 gcc -g3 when debugging.
4207 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4209 * lisp.mk: Adjust comments to the fact that term/internal is now
4210 loaded from loadup.el.
4212 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4213 (msdos_fatal_signal): New function.
4214 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4217 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4218 for GCC versions before 4.
4219 (emacs_raise): Define to call msdos_fatal_signal.
4221 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4222 iterator when starting in the middle of a display or overlay
4225 2012-11-03 Chong Yidong <cyd@gnu.org>
4227 * process.c (wait_reading_process_output): Clean up the last
4230 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4232 * process.c (wait_reading_process_output): Avoid a race condition
4233 with SIGIO delivery (Bug#11536).
4235 2012-11-03 Chong Yidong <cyd@gnu.org>
4237 * buffer.c (cursor_type): Untabify docstring.
4239 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4241 * frame.h (struct frame): Drop can_have_scroll_bars member
4242 which is meaningless for a long time. Adjust comments.
4243 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4244 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4246 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4248 * window.c (decode_next_window_args): Update window arg after
4249 calling decode_live_window and so fix crash reported at
4250 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4251 by Juanma Barranquero <lekktu@gmail.com>.
4252 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4253 * font.c (Ffont_at): Likewise.
4255 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4257 * widget.c (resize_cb): New function.
4258 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4259 (EmacsFrameResize): Check if all is up to date before changing frame
4262 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4264 Implement backtrace output for fatal errors on MS-Windows.
4265 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4266 (BACKTRACE_LIMIT_MAX): New macro.
4267 (w32_backtrace): New function.
4268 (emacs_abort): Use w32_backtrace when the user chooses not to
4269 attach a debugger. Update the text of the abort dialog.
4271 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4273 Window-related stuff cleanup here and there.
4274 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4275 Use decode_any_window.
4276 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4277 * xdisp.c (Fformat_mode_line): Likewise.
4278 * font.c (Ffont_at): Use decode_live_window.
4279 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4280 * window.c (decode_next_window_args): Likewise.
4281 (decode_any_window): Remove static.
4282 * window.h (decode_any_window): Add prototype.
4283 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4284 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4287 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4289 Remove pad from struct input_event.
4290 * termhooks.h (struct input_event): Remove padding field.
4292 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4293 member is never cons for a long time. Adjust comment.
4294 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4295 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4296 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4297 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4299 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4301 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4303 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4305 Fix crash when using Emacs as commit editor for git (Bug#12697).
4306 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4307 and it is configured in conf_post.h.
4308 (Fcall_process): Don't invoke both setsid and setpgid; the former
4309 is enough, if it exists.
4310 * callproc.c (Fcall_process, child_setup):
4311 * process.c (create_process): Use setpgid.
4312 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4314 * dispnew.c (init_display): Initialize the foreground group
4315 if we are running a tty display.
4316 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4317 * lisp.h (init_foreground_group): New decl.
4318 * sysdep.c (inherited_pgroup): New static var.
4319 (init_foreground_group, tcsetpgrp_without_stopping)
4320 (narrow_foreground_group, widen_foreground_group): New functions.
4321 (init_sys_modes): Narrow foreground group.
4322 (reset_sys_modes): Widen foreground group.
4324 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4326 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4328 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4330 * minibuf.c (read_minibuf): Restore current buffer since
4331 choose_minibuf_frame calling Fset_frame_selected_window may
4332 change it (Bug#12766).
4334 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4336 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4338 2012-10-30 Kenichi Handa <handa@gnu.org>
4340 * font.c (Ffont_at): If WINDOW is specified and it is not
4341 displaying the current buffer, signal an error.
4343 2012-10-29 Daniel Colascione <dancol@dancol.org>
4345 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4346 In preparation for fixing bug#12739, move these functions from
4349 * coding.h, coding.c: ... to here, and compile them only when
4350 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4351 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4353 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4355 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4356 (timer_loop, getitimer, setitimer): Use it instead of
4357 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4359 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4362 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4364 * nsterm.m (NO_APPDEFINED_DATA): New define.
4365 (last_appdefined_event_data): New variable
4366 (last_appdefined_event): Remove.
4367 (ns_select): Initialize t from last_appdefined_event_data instead
4368 of [last_appdefined_event data1].
4369 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4370 remove last_appdefined_event (Bug#12698).
4372 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4374 * frame.c (x_set_font): Catch internal error.
4376 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4378 Avoid overflow in w32 implementation of interval timers.
4379 When possible, for ITIMER_PROF count only times the main thread
4381 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4382 'volatile ULONGLONG' types. All the other data which was
4383 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4384 (GetThreadTimes_Proc): New typedef.
4385 (w32_get_timer_time): New function, returns a suitable time value
4387 (timer_loop): Enter critical section when accessing ULONGLONG
4388 values of the itimer_data struct, as these accesses are no longer
4389 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4390 Remove unused variable.
4391 (init_timers): Initialize s_pfn_Get_Thread_Times.
4392 (start_timer_thread): Don't assign itimer->caller_thread here.
4393 (getitimer): Assign itimer->caller_thread here.
4394 (setitimer): Always call getitimer to get the value of ticks_now.
4395 (sys_spawnve): Avoid compiler warning about format mismatch.
4397 2012-10-26 Eli Zaretskii <eliz@gnu.org>
4399 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4400 mouse movement events if the menu bar is active. This avoids
4401 producing a busy "hour-glass" cursor by Windows if the mouse
4402 pointer is positioned over a tooltip shown for some menu item.
4404 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4406 Don't assume process IDs fit in int.
4407 * emacs.c (shut_down_emacs) [!DOS_NT]:
4408 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4409 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4410 Use pid_t, not int, to store process IDs, as 'int'
4411 is not wide enough on a few platforms (e.g., AIX and IRIX).
4413 2012-10-23 Kenichi Handa <handa@gnu.org>
4415 The following change is to make face-font-rescale-alist work
4416 correctly for non-ASCII fonts.
4418 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4419 (font_open_for_lface): Handle Vface_font_rescale_alist.
4421 2012-10-23 Chong Yidong <cyd@gnu.org>
4423 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4425 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
4427 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
4429 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
4431 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
4434 2012-10-21 Glenn Morris <rgm@gnu.org>
4436 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4438 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4440 Port to OpenBSD 5.1.
4441 * frame.c (Fmouse_position, Fmouse_pixel_position):
4442 * xdisp.c (produce_stretch_glyph):
4443 Declare local vars only when they're needed.
4444 This is clearer and avoids a warning on OpenBSD about unused vars.
4445 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
4446 This is safer, and avoids OpenBSD warnings about unused vars.
4447 * keyboard.c (record_menu_key): Remove unnecessary decl.
4448 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4449 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4450 as our definition clashes with OpenBSD's.
4451 * xfaces.c (load_face_colors, check_lface_attrs)
4452 (get_lface_attributes_no_remap, get_lface_attributes)
4453 (lface_fully_specified_p, x_supports_face_attributes_p)
4454 (tty_supports_face_attributes_p, face_fontset, realize_face)
4455 (realize_x_face, realize_tty_face):
4456 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4457 merely Lisp_Object *. This is more informative and avoids
4458 a warning on OpenBSD about accessing beyond an object's size.
4460 2012-10-20 Chong Yidong <cyd@gnu.org>
4462 * lread.c (Fload): Doc fix (Bug#12592).
4464 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
4466 * font.c (Ffont_at): Fix previous change.
4468 2012-10-19 Eli Zaretskii <eliz@gnu.org>
4470 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
4471 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
4474 * alloc.c (NSTATICS): Decrease to 0x800.
4476 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

4481 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
4483 * nsterm.m (ns_select): Check writefds before call to
4484 FD_ISSET (Bug#12668).
4486 2012-10-18 Daniel Colascione <dancol@dancol.org>
4488 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4489 (staticpro): If we run out of staticpro slots, die with an
4490 informative error instead of just calling emacs_abort.
4492 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4494 Fix two flaws reported by Dmitry Antipov.
4495 * window.c (Ftemp_output_buffer_show): Remove.
4496 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
4497 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
4499 2012-10-17 Eli Zaretskii <eliz@gnu.org>

4505 ($(BLD)/fileio.$(O)):
4506 ($(BLD)/dispnew.$(O)): Update dependencies.
4508 * w32term.h (w32_initialize_display_info, initialize_w32_display):
4511 * w32proc.c: Include ctype.h.
4513 * w32.h (init_environment, check_windows_init_file)
4514 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
4515 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
4516 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
4517 (sys_link): Add prototypes.
4519 * w32.c: Include w32select.h.
4520 (sys_access, e_malloc, sys_select): Add prototypes.
4521 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
4523 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
4525 * unexw32.c: Include lisp.h and w32.h.
4527 * term.c [WINDOWSNT]: Include w32term.h.
4529 * process.c [WINDOWSNT]: Add prototype of sys_select.
4531 * fileio.c [WINDOWSNT]: Include w32.h.
4533 * dispnew.c [WINDOWSNT]: Include w32.h.
4535 * cygw32.c (Fcygwin_convert_path_to_windows)
4536 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
4537 Lisp_Object values. (Bug#12661)
4539 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
4540 to Lisp_Object. (Bug#12661)
4542 2012-10-17 Kenichi Handa <handa@gnu.org>

4550 reset its buffer pointer to NULL (Bug#12652).
4552 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
4554 Do not verify indirection counters of killed buffers (Bug#12579).
4555 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
4556 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.
4558 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
4560 * alloc.c (Fmake_byte_code): Fix typo in comment.
4561 * print.c (print_interval): Define as static to match prototype.
4562 * indent.c (disptab_matches_widthtab, recompute_width_table):
4565 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>

4576 2012-10-15 Martin Rudalics <rudalics@gmx.at>
4578 * window.c (Fwindow_end): Rewrite check whether cached position
4579 can be used (Bug#12600).
4580 (resize_frame_windows, grow_mini_window, shrink_mini_window):
4581 Set windows_or_buffers_changed.
4583 2012-10-15 Daniel Colascione <dancol@dancol.org>
4585 * dbusbind.c: Fix cygw32 build break when compiling with dbus
4586 enabled by undefining the symbol "interface", which the platform
4587 headers define to something incompatible.
4589 2012-10-14 Daniel Colascione <dancol@dancol.org>
4591 * image.c (init_tiff_functions, init_imagemagick_functions)
4592 (init_svg_functions): Fix cygw32 build break by using these
4593 functions only when WINDOWSNT _and_ HAVE_NTGUI.

4601 * gtkutil.c (xg_set_widget_bg): Divide by 65535 (Bug#12612).
4603 2012-10-13 HANATAKA, Shinya <bogytech@gmail.com> (tiny change)

4608 2012-10-13 Andreas Schwab <schwab@linux-m68k.org>
4610 * fileio.c: Formatting fixes.
4612 2012-10-13 Paul Eggert <eggert@cs.ucla.edu>
4614 Fix some stat-related races.
4615 * fileio.c (Fwrite_region): Avoid race condition if a file is
4616 removed or renamed by some other process immediately after Emacs
4617 writes it but before Emacs stats it. Do not assume that stat (or
4619 * image.c (slurp_file): Resolve the file name with fopen + fstat
4620 rather than stat + fopen.
4621 (pbm_read_file) [0]: Remove unused code with stat race.
4622 * process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]:
4623 Remove ineffective code with stat race.

4646 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
4648 * fileio.c (check_existing): New function.
4649 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
4650 instead of calling 'stat', when what's needed is to check whether
4651 a file exists. This avoids expensive system calls on MS-Windows.
4654 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
4656 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
4657 determine whether a file exists and is not a directory.
4659 * lisp.h (check_existing): Add prototype.
4661 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
4663 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

4703 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
4705 * marker.c (cached_modiff): EMACS_INT, not int.
4707 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
4708 instead of having a wrong decl.

4745 * keyboard.c (timers_run, swallow_events)
4746 (detect_input_pending_run_timers):
4747 * process.c (wait_reading_process_output):
4748 Use unsigned for counter where wraparound-on-overflow is desired,
4749 since unsigned is guaranteed to have that behavior and signed is not.
4750 (read_char): Use ptrdiff_t for string length.
4751 (get_input_pending): Remove first argument, since it was always
4752 the same pointer-to-int (now pointer-to-boolean) &input_pending,
4753 and behave as if it had that value. Return new value of
4754 input_pending. All callers changed.
4755 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4756 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
4758 * keymap.c (push_key_description): Omit last arg, which was always 1.
4759 All callers changed.
4761 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
4763 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

4778 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
4779 Don't include termopts.h.
4781 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
4783 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
4785 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4787 * commands.h (immediate_quit): Remove duplicate decl.
4789 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
4791 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
4793 (nsfont_open): Remove setting of Vfonts_in_cache.
4794 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
4796 2012-10-09 Eli Zaretskii <eliz@gnu.org>
4798 * w32fns.c (w32_last_error): Change the return value to DWORD, to
4799 match what GetLastError returns. Explain why the function is
4802 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4803 'is_tooltip_frame', to avoid confusion with its global namesake.
4805 2012-10-08 Daniel Colascione <dancol@dancol.org>
4807 * xdisp.c (start_hourglass): Call w32_note_current_window when
4808 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4809 build that caused Emacs to display the hourglass cursor forever.
4811 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4812 which is broken under remote desktop, calculate the number of
4813 colors available for a display based on the display's number of
4814 planes and number of bits per pixel per plane. (bug#10397).
4816 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4818 * nsfont.m (Vfonts_in_cache): New variable.
4819 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4820 are used. Add cached fonts to Vfonts_in_cache.
4821 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4823 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4825 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4827 (FONT_H): Define after FRAME_H.
4828 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4829 Update dependencies.
4831 * w32term.c: Remove leftover declaration of keyboard_codepage.
4833 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4835 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4836 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4837 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4838 (GLOBAL_SOURCES): Add cygw32.c.
4839 ($(BLD)/unexw32.$(O)):
4841 ($(BLD)/w32console.$(O)):
4842 ($(BLD)/w32fns.$(O)):
4843 ($(BLD)/w32heap.$(O)):
4844 ($(BLD)/w32menu.$(O)):
4845 ($(BLD)/w32proc.$(O)): Add w32common.h.
4847 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4849 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4851 2012-10-08 Daniel Colascione <dancol@dancol.org>
4853 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4854 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4855 accidental message numbering hole. Change other messages to
4858 * w32select.h (HAVE_W32SELECT): Remove.
4860 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4861 w32common.h instead of w32heap.h.
4863 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4864 (get_allocation_unit, get_processor_type, get_w32_major_version)
4865 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4866 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4867 (OS_NT, os_subtype, cache_system_info): Move declarations to
4870 * w32heap.c: Include w32common.h.
4871 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4872 (w32_minor_version, w32_build_number, w32_subtype):
4873 Remove duplicate definitions.
4875 * w32fns.c: Include w32common.h; include w32heap.h only in
4878 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4879 Use `report_file_error' instead of `error' in order to better
4880 inform users of what went wrong. Increase NTGUI_UNICODE file
4881 dialog box file name length to 32k, the maximum allowed by the NT
4884 * w32common.h: New file.
4885 (ROUND_UP, ROUND_DOWN, get_page_size)
4886 (get_allocation_unit, get_processor_type, get_w32_major_version)
4887 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4888 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4889 (OS_NT, os_subtype, cache_system_info): Move here.
4891 * unexw32.c, unexcw.c: Include w32common.h.
4893 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4894 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4895 to call syms_of_w32select.
4897 * cygw32.h: Remove obsolete EXFUN declarations.
4899 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4901 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4902 of w32inevt.o from SOME_MACHINE_OBJECTS.
4904 2012-10-08 Daniel Colascione <dancol@dancol.org>
4906 * image.c: Permanent fix for JPEG compilation issue --- limit
4907 jpeglib `boolean' redefinition to Cygwin builds.
4909 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4911 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4913 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4916 2012-10-08 Daniel Colascione <dancol@dancol.org>
4918 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4919 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4920 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4921 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4922 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4923 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4924 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4925 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4926 now a supported configuration.
4928 * Makefile.in: consolidate image variables into LIBIMAGE; add
4929 W32_OBJ and W32_LIBS. Compile new files.
4932 (_DebPrint) declare tracing facility for W32 debugging. We need
4933 to unify tracing later.
4935 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4936 unconditional use of W32 Unicode functions. Cygwin runs only on
4937 100% Unicode operating systems.
4939 * cygw32.c: New file. Define Cygwin-specific facilities.
4940 (Fcygwin_convert_path_to_windows)
4941 (Fcygwin_convert_path_from_windows): New user functions for
4942 accessing Cygwin path-munging routines.
4944 * cygw32.h: New file.
4945 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4946 UTF-16LE strings temporarily inside non-Lisp-visible string
4949 (w32_strerror): Just what it says on the tin.
4951 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4952 also run for Cygwin; both systems have the same problem with using
4953 GUI facilities in a forked child. Also call syms_of_cygw32,
4954 syms_of_w32select in correct places.
4956 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4957 needs fork-then-exec for daemon launching.
4959 * font.h: Include frame.h.
4961 * image.c: Use the image library cache machinery only when we're
4962 compiling for native WINDOWSNT; Cygwin can use shared libraries
4963 like any other Unixlike system.
4965 * keyboard.c: Clarify a comment regarding the input loop.
4967 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4968 functions directly instead of trying to detect at runtime that our
4969 host operating system supports them. We make this change for two
4970 reasons: Cygwin lacks support for the multibyte character
4971 conversion functions used by the legacy menu code, and Cygwin
4972 never needs to rely on non-Unicode APIs.
4974 * unexw32.c (hinst): Declare extern.
4976 * w32.c: Change header order;
4977 (w32_strerror): Move to w32fns.c because we need it for
4978 non-WINDOWSNT builds.
4980 * w32.h: Add #error macro to make sure we don't include w32.h for
4981 Cygwin builds. Remove w32select declarations.
4983 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4984 w32fns.c. w32console.c is WINDOWSNT-only.
4986 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4987 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4989 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4990 (w32_major_version, w32_minor_version, w32_build_number)
4991 (os_subtype, sound_type): Define here
4992 (w32_defined_color): Make color parameter const for consistency
4993 with other _defined_color functions.
4994 (w32_createwindow): Unconditionally call w32_init_class instead of
4995 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4996 through the code is complex and unnecessary because class
4997 registration is practically free.
4998 (w32_name_of_message): New EMACSDEBUG-only function.
4999 (Fset_message_beep): Move here
5000 (Fx_open_connection): Require that the display name for Windows be
5001 "w32" for consistency, emacsclient disambiguation, and maybe, one
5002 day, multi-window-system support.
5003 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5004 Cygwin files for W32 GUI facilities, since these clearly don't
5005 expect Cygwin names.
5006 (_DebPrint): Define.
5007 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5008 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5009 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5010 (w32_last_error): Remove.
5012 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5014 * w32heap.c (syspage_mask): Declare here.
5015 (cache_system_info): Remove.
5017 * w32inevt.c (faked_key): Define globally, not statically.
5018 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5019 (w32_console_toggle_lock_key): Move to w32fns.c.
5021 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5023 * w32proc.c (_DebPrint): Move to w32fns.c.
5024 * w32select.c: Include string.h, stdio.h for Cygwin.
5025 * w32select.h: New File.
5027 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5029 (w32_message_fd): New variable. Under Cygwin, holds the file
5030 descriptor the system used to tell us about pending thread
5033 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5034 that prevented compilation under non-WINDOWSNT systems.
5036 (w32_initialize): Open /dev/windows and assign it to
5037 w32_message_fd. Provide w32 feature.
5039 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5040 (WM_EMACS_INPUT_READY): add.
5041 (prepend_msg, w32_message_fd): Declare globally.
5044 (keyboard_handle): Use only when WINDOWSNT.
5045 (notify_msg_ready): New function. Posts a message to the main
5046 thread's message queue under CYGWIN, which wakes up the main
5047 thread from select(2) by making the /dev/windows file descriptor
5048 ready. Under WINDOWSNT, it sets an event the same way the old
5051 (post, prepend_msg): Actually call notify_msg_ready instead of
5052 setting the input event directly.
5054 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5056 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5057 but it still has blocs in it, don't return it to the system,
5058 instead of aborting. (Bug#12402)
5060 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5062 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5064 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5065 MAC_OS_X_VERSION_10_6.
5066 (syms_of_nsterm): Remove comment about Panther and above for
5068 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5069 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5070 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5072 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5073 MAC_OS_X_VERSION_10_4.
5075 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5076 MAC_OS_X_VERSION_10_2.
5078 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.

5093 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5095 Improve sys_siglist detection.
5096 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5097 defined as a macro, as is done in Solaris.
5098 (sys_siglist_entries): New macro.
5099 (save_strsignal): Use it.
5100 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5101 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5103 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5105 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5106 fullscreen/Fullscreen.
5108 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5109 tobar_height is new.
5111 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5112 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5113 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

5126 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5128 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5130 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5132 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5133 that time stamps of directories could also be changed.
5134 Don't request the too broad GENERIC_WRITE, only the more restrictive
5135 FILE_WRITE_ATTRIBUTES access rights.
5137 * fileio.c (Fset_file_times): Special-case ignoring errors for
5138 directories only on MSDOS, not on MS-Windows.
5140 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5142 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5144 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5146 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5147 see whether CreateFile failed.
5149 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5151 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5152 to avoid similar races.
5153 * keyboard.c (pending_signals): Now bool, not int.
5155 Port timers to OpenBSD, plus check for timer failures.
5156 OpenBSD problem reported by Han Boetes.
5157 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5159 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5160 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5161 like OpenBSD, which has timer_settime but does not declare it.
5162 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5163 whether to use itimerspec-related primitives. All uses of
5164 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5166 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5168 * profiler.c (handle_profiler_signal): Fix a malloc race
5169 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5171 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5173 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5175 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5177 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5178 consistent with the change in return value of 'safe_strsignal'.
5180 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5182 Prefer plain 'static' to 'static inline' (Bug#12541).
5183 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5184 (bidi_set_sor_type, bidi_push_embedding_level)
5185 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

5190 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5191 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5192 Now 'static', not 'static inline'.
5194 Count overruns when profiling; change units to ns.
5195 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5196 Give extra weight to samples after overruns, to attempt to count
5197 the time more accurately.
5198 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5199 the underlying primitives nominally do ns.
5200 (Fprofiler_cpu_start): Document the change. Mention that
5201 the sampling intervals are only approximate.
5203 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5205 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5207 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5208 case for the special 0 coding-system.
5210 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5211 (Fmake_overlay): Remove redundant tests.
5212 (fix_start_end_in_overlays): Remove redundant recentering.
5214 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5216 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5217 Update dependencies.
5219 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5221 Fix a malloc race condition involving strsignal.
5222 A signal can arrive in the middle of a malloc, and Emacs's signal
5223 handler can invoke strsignal, which can invoke malloc, which is
5224 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5225 Fix it by altering the signal handler so that it does not invoke
5227 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5228 * process.c (status_message): Use const pointer, in case strsignal
5229 is #defined to safe_strsignal.
5230 * sysdep.c (sys_siglist, init_signals): Always define and
5231 initialize a substitute sys_siglist if the system does not define
5232 one, even if HAVE_STRSIGNAL.
5233 (safe_strsignal): Rename from strsignal. Always define,
5234 using sys_siglist. Return a const pointer.
5235 * syssignal.h (safe_strsignal): New decl.
5236 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5238 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5240 * w32proc.c (timer_loop): Fix code that waits for timer
5241 expiration, to avoid high CPU usage.
5243 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5245 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5246 (sweep_weak_table): Remove redundant prototypes.
5248 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5250 * emacs.c: Move the inclusion of TERM_HEADER after including
5251 windows.h on WINDOWSNT. This avoids compilation problems with
5254 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5256 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5257 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5258 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5259 as the previous version used 'void *'.
5261 * ralloc.c (ROUNDUP): Fix last change.
5262 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5265 * w32proc.c <disable_itimers>: New static flag.
5266 (init_timers): Initialize it to zero, after creating the critical
5267 sections used by the timer threads.
5268 (term_timers): Set to 1 before deleting the critical sections.
5269 (getitimer, setitimer): If disable_itimers is non-zero, return an
5270 error indication without doing anything. Reported by Fabrice
5271 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5272 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5274 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5277 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5278 term_ntproc after all the other bookkeeping, to get timers working
5279 as long as possible.
5281 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5283 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5284 Suggested by Juri Linkov in
5285 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5287 Prefer plain 'static' to 'static inline' (Bug#12541).
5288 With static functions, modern compilers inline pretty well by
5289 themselves; advice from programmers often hurts as much as it helps.
5290 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5291 this change shrinks the text size of the Emacs executable by 1.1%
5292 without affecting CPU significantly in my benchmark.
5293 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

5373 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
5375 Revert the FOLLOW-SYMLINKS change for file-attributes.
5376 Doing it right would require several changes to Tramp, and there's
5377 not enough time to get that tested before the freeze today.
5378 * dired.c (directory_files_internal, Ffile_attributes):
5381 * frame.c (x_report_frame_params): Port better to wider ints.
5382 Do not assume that EMACS_UINT is the same width as uprintmax_t,
5383 or that pointers can be printed in 15 decimal digits.
5384 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

5420 * vm-limit.c (lim_data): Now size_t.
5421 (check_memory_limits): Adjust prototypes of real_morecore and
5422 __morecore to receive argument of type ptrdiff_t. Use size_t for

5502 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
5504 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
5506 * w32.h (init_timers, term_timers): Add prototypes.
5508 2012-09-30 Kenichi Handa <handa@gnu.org>
5510 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
5511 to the buffer relocation which may be caused by ccl_driver.

5545 (EmacsView): Add variables for fullscreen.
5546 (handleFS, setFSValue, toggleFullScreen): New in EmacsView.
5547 (EmacsFSWindow): New interface for fullscreen.
5549 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
5551 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
5553 2012-09-30 Chong Yidong <cyd@gnu.org>
5555 * fns.c (Frandom): Doc fix.
5557 2012-09-30 Martin Rudalics <rudalics@gmx.at>

5560 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
5562 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5564 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
5565 Suggested by Eli Zaretskii in
5566 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
5568 2012-09-30 Eli Zaretskii <eliz@gnu.org>
5570 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
5571 HAVE_TIMER_SETTIME is defined.
5573 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5575 Profiler improvements: more-accurate timers, overflow checks.
5576 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
5577 signal.h, setjmp.h. Include systime.h instead.
5578 (saturated_add): New function.
5579 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
5580 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
5581 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
5583 (enum profiler_cpu_running): New enum.
5584 (profiler_cpu_running): Now of that enum type, not bool.
5585 All uses changed to store the new value.
5586 (handle_profiler_signal): Rename from sigprof_handler_1,
5587 for consistency with other handlers. Do not check whether
5588 cpu_log is a hash-table if garbage collecting, since it
5589 doesn't matter in that case.
5590 (deliver_profiler_signal): Rename from sigprof_handler,
5591 for consistency with other handlers.
5592 (setup_cpu_timer): New function, with much of what used to be in
5593 Fprofiler_cpu_start. Check for out-of-range argument.
5594 Prefer timer_settime if available, and prefer
5595 thread cputime clocks, then process cputime clocks, then
5596 monotonic clocks, to the old realtime clock. Use make_timeval
5597 to round more-correctly when falling back to setitimer.
5598 (Fprofiler_cpu_start): Use it.
5599 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5600 Don't assume that passing NULL as the 2nd argument of setitimer
5601 is the same as passing a pointer to all-zero storage.
5602 Ignore SIGPROF afterwards.
5603 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5604 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5605 non-fatal signal handlers. Ignore SIGPROF on startup.
5606 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5607 in profiler.c, since sysdep.c now uses it.
5609 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
5610 Suggested by Eli Zaretskii in
5611 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

5633 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
5634 Qautomatic_redisplay and change the symbol name. All users changed.

5663 * character.h (MAYBE_UNIFY_CHAR): Remove.
5664 * charset.c, charset.h (maybe_unify_char): Now static.
5665 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5666 Since this stuff is now private to charset.c, there's no need for
5667 a public macro and no need to inline by hand.

5700 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
5702 Prefer POSIX timers if available.
5703 They avoid a race if the timer is too close to the current time.
5704 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
5705 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

5731 * w32.h (Vlibrary_cache): Do not declare.
5733 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5735 * w32proc.c (sys_signal): Handle all signals defined by the
5736 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5737 handlers for signals supported by Windows. Don't override
5738 term_ntproc as the handler for SIGABRT.
5739 (sigaction): Rewrite to call sys_signal instead of duplicating its
5741 (sys_kill): Improve commentary.
5743 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5744 consistency with a signature of a signal handler. All callers
5746 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5747 install term_ntproc as a signal handler for SIGABRT, as that
5748 should be done by the dumped Emacs.
5750 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5752 * w32select.c (term_w32select): Protect against repeated
5753 invocation by setting clipboard_owner to NULL after calling
5756 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5757 and term_ntproc to their modified signatures.
5759 * character.c (char_string, string_char): Remove calls to

5768 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5770 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5771 when encountering an unknown bytecode.
5773 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5775 image.c, indent.c: Use bool for booleans.
5776 * dispextern.h (struct image_type): Members valid_p, load, init

5778 * image.c: Omit unnecessary static decls.
5779 (x_create_bitmap_mask, x_build_heuristic_mask):

5817 Move pid_t related decls out of lisp.h.
5818 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5819 (interruptible_wait_for_termination):
5820 Move these decls from lisp.h to syswait.h, since they use pid_t.
5821 Needed on FreeBSD; see Herbert J. Skuhra in
5822 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5823 * callproc.c: Include syswait.h.

5869 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5871 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5872 fatal_error_backtrace.
5874 * w32proc.c (sys_kill): Undo last change: don't do anything when
5875 invoked to deliver SIGABRT to our own process. This is now
5876 handled by emacs_raise.
5878 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5880 * w32term.c (w32_read_socket): Remove leftover reference to
5881 interrupt_input_pending.
5883 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5885 Do not use SA_NODEFER.
5886 Problem reported by Dani Moncayo in
5887 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5889 * sysdep.c (emacs_abort): Do not reset signal handler.
5890 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5891 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5892 wanted even on POSIXish hosts, and it doesn't work on Windows.
5894 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5896 * xterm.c (x_term_init): Call fixup_locale before and after calling
5897 gtk_init (Bug#12392).
5899 2012-09-23 Chong Yidong <cyd@gnu.org>
5901 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5902 Vdynamic_library_alist.
5904 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5905 (Fgnutls_available_p): Caller changed.
5907 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5908 (Flibxml_parse_xml_region): Likewise.
5910 * dispextern.h (struct image_type): Remove arg from init function.
5912 * image.c (Finit_image_library, lookup_image_type)
5913 (define_image_type): Remove now-unneeded second arg.
5914 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5915 (init_tiff_functions, init_gif_functions, init_svg_functions):
5916 Arglist and w32_delayed_load calling convention changed.
5917 (gs_type): Remove init_gs_functions; there is no such function.
5918 (valid_image_p, make_image): Fix caller to lookup_image_type.
5920 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5922 Simplify and avoid signal-handling races (Bug#12471).
5924 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5925 Avoid recursive loop if there's a fatal error in the function itself.
5926 * atimer.c (pending_atimers):
5927 * blockinput.h: Don't include "atimer.h"; no longer needed.
5928 (interrupt_input_pending): Remove. All uses removed.
5929 pending_signals now counts both atimers and ordinary interrupts.
5930 This is less racy than having three separate pending-signal flags.
5931 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5933 Rename from their upper-case counterparts BLOCK_INPUT,
5934 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5935 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5936 This makes it easier to access volatile variables more accurately.
5937 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5938 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5939 that's more reliable if the code is buggy and sets
5940 interrupt_input_blocked to a negative value. All uses changed.
5941 * atimer.c (deliver_alarm_signal):
5942 Remove. No need to deliver this to the parent; any thread can
5943 handle this signal now. All uses replaced by underlying handler.
5944 * atimer.c (turn_on_atimers):
5945 * dispnew.c (handle_window_change_signal):
5946 * emacs.c (handle_danger_signal):
5947 * keyboard.c (kbd_buffer_get_event):
5948 Don't reestablish signal handler; not needed with sigaction.
5949 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5951 Rework to avoid unnecessary accesses to volatile variables.
5952 (UNBLOCK_INPUT_TO): Now a function.
5953 (totally_unblock_input, unblock_input): New decls.
5954 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5955 (init_data): Remove. Necessary stuff now done in init_signal.
5956 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5957 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5958 (fatal_error_code): Remove; no longer needed.
5959 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5960 it doesn't always backtrace. All uses changed. No need to reset
5961 signal to default, since sigaction and/or die does that for us now.
5962 Use emacs_raise (FOO), not kill (getpid (), FOO).
5963 (main): Check more-accurately whether we're dumping.
5964 Move fatal-error setup to sysdep.c
5965 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5966 * gtkutil.c (xg_get_file_name, xg_get_font):
5967 Remove no-longer-needed signal-mask manipulation.
5968 * keyboard.c, process.c (POLL_FOR_INPUT):
5969 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5970 * keyboard.c (read_avail_input): Remove.
5971 All uses replaced by gobble_input.
5972 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5973 (kbd_buffer_store_event_hold, gobble_input):
5974 (record_asynch_buffer_change) [USABLE_SIGIO]:
5975 (store_user_signal_events):
5976 No need to mess with signal mask.
5977 (gobble_input): If blocking input and there are terminals, simply
5978 set pending_signals to 1 and return. All hooks changed to not
5979 worry about whether input is blocked.
5980 (process_pending_signals): Clear pending_signals before processing
5981 them, in case a signal comes in while we're processing.
5982 By convention callers now test pending_signals before calling us.
5983 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5984 New functions, to support changes to blockinput.h.
5985 (handle_input_available_signal): Now extern.
5986 (reinvoke_input_signal): Remove. All uses replaced by
5988 (quit_count): Now volatile, since a signal handler uses it.
5989 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5990 All callers changed. Block SIGINT only if not already blocked.
5991 Clear sigmask reliably, even if Fsignal returns, which it can.
5992 Omit unnecessary accesses to volatile var.
5993 (quit_throw_to_read_char): No need to restore sigmask.
5994 * keyboard.c (gobble_input, handle_user_signal):
5995 * process.c (wait_reading_process_output):
5996 Call signal-handling code rather than killing ourselves.
5997 * lisp.h: Include <float.h>, for...
5998 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5999 (pending_signals): Now volatile.
6000 (syms_of_data): Now const if IEEE floating point.
6001 (handle_input_available_signal) [USABLE_SIGIO]:
6002 (terminate_due_to_signal, record_child_status_change): New decls.
6003 * process.c (create_process): Avoid disaster if memory is exhausted
6004 while we're processing a vfork, by tightening the critical section
6006 (send_process_frame, process_sent_to, handle_pipe_signal)
6007 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6009 (send_process): No need for setjmp/longjmp any more, since the
6010 SIGPIPE stuff is now gone. Instead, report an error if errno
6012 (record_child_status_change): Now extern. PID and W are now args.
6013 Return void, not bool. All callers changed.
6014 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6015 Remove. All uses removed. This bug should be fixed now in a
6017 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6018 and record the child status change directly. This avoids the
6019 need to futz with the signal mask.
6020 (process_fatal_action): Move here from emacs.c.
6021 (emacs_sigaction_flags): New function, containing
6022 much of what used to be in emacs_sigaction_init.
6023 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6024 caught by emacs, to make races less likely.
6025 (deliver_process_signal): Rename from handle_on_main_thread.
6027 (BACKTRACE_LIMIT_MAX): Now at top level.
6028 (thread_backtrace_buffer, threadback_backtrace_pointers):
6030 (deliver_thread_signal, deliver_fatal_thread_signal):
6031 New functions, for more-accurate delivery of thread-specific signals.
6032 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6033 (deliver_arith_signal): Handle in this thread, not
6034 in the main thread, since it's triggered by this thread.
6035 (maybe_fatal_sig): New function.
6036 (init_signals): New arg DUMPING so that we can be more accurate
6037 about whether we're dumping. Caller changed.
6038 Treat thread-specific signals differently from process-general signals.
6039 Block all signals while handling fatal error; that's safer.
6040 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6042 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6043 Ignore SIGPIPE unless batch.
6044 (emacs_backtrace): Output backtrace for the appropriate thread,
6045 which is not necessarily the main thread.
6046 * syssignal.h: Include <stdbool.h>.
6047 (emacs_raise): New macro.
6048 * xterm.c (x_connection_signal): Remove; no longer needed
6049 now that we use sigaction.
6050 (x_connection_closed): No need to mess with sigmask now.
6051 (x_initialize): No need to reset SIGPIPE handler here, since
6052 init_signals does this for us now.
6054 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6056 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6057 background rect may be larger (Bug#12245).
6059 2012-09-23 Chong Yidong <cyd@gnu.org>
6061 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6063 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6065 * .gdbinit: Just stop at fatal_error_backtrace.
6066 See Stefan Monnier's request in
6067 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6068 Remove no-longer-used query of system type.
6070 2012-09-22 Chong Yidong <cyd@gnu.org>
6072 * search.c (Freplace_match): Doc fix (Bug#12325).
6074 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6076 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6077 (Fline_end_position): Doc fix.
6079 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6081 2012-09-22 Chong Yidong <cyd@gnu.org>
6083 * dispextern.h (struct image_type): Add new slot, storing a type
6084 initialization function.
6086 * image.c (define_image_type): Call the image initializer function
6087 if it is defined. Arguments and return value changed.
6088 (valid_image_p, make_image): Callers changed.
6089 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6090 (gif_type, imagemagick_type, svg_type, gs_type):
6091 Add initialization functions.
6092 (Finit_image_library): Call lookup_image_type.
6093 (CHECK_LIB_AVAILABLE): Macro deleted.
6094 (lookup_image_type): Call define_image_type here, rather than via
6095 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6096 (syms_of_image): Move define_image_type calls for xbm_type and
6097 pbm_type to lookup_image_type.
6099 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6101 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6102 'idle_timers' from here ...
6103 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6104 lists, to avoid infloops when the timer does something stupid,
6105 like reinvoke itself with the same or smaller time-out.
6108 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6110 * window.c (Fsplit_window_internal): Handle only Qt value of
6111 Vwindow_combination_limit separately.
6112 (Qtemp_buffer_resize): New symbol.
6113 (Vwindow_combination_limit): New default value.
6116 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6118 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6119 the new overlay string. (Bug#10159)
6121 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6123 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6124 or that fprintf is async-signal-safe. POSIX doesn't require
6127 2012-09-22 Chong Yidong <cyd@gnu.org>
6129 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6132 2012-09-22 Kenichi Handa <handa@gnu.org>
6134 * composite.c (composition_reseat_it): Handle the case that a
6135 grapheme cluster is not covered by a single font (Bug#12352).
6137 2012-09-21 Chong Yidong <cyd@gnu.org>
6139 * image.c (define_image_type): Avoid adding duplicate types to
6140 image_types (Bug#12463). Suggested by Jörg Walter.
6142 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6144 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6145 (print_load_command_name): Add case LC_DATA_IN_CODE.
6146 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6148 2012-09-21 Glenn Morris <rgm@gnu.org>
6150 * eval.c (Frun_hook_with_args_until_success)
6151 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6153 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6155 * fileio.c (Ffile_selinux_context): Only call freecon when
6156 lgetfilecon succeeded.
6157 (Fset_file_selinux_context): Likewise. (Bug#12444)
6159 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6161 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6162 reordering, locate the cursor by calling set_cursor_from_row; if
6163 that fails, clear the desired glyph matrix before returning a
6164 failure indication to the caller. Fixes leaving garbled display
6165 when fast scrolling with a down-key. (Bug#12403)
6166 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6167 scrolling through multibyte text.
6169 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6171 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6172 calling mark_vectorlike since that's the one that marks the window.
6173 (mark_discard_killed_buffers): Mark the final cdr.
6174 * window.h (struct window): Move prev/next_buffers to the
6175 non-standard fields.
6176 * window.c (make_window): Initialize prev/next_buffers manually.
6178 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6180 Omit unused arg EXPECTED from socket hooks.
6181 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6182 * nsterm.m (ns_term_init):
6183 * termhooks.h (struct terminal.read_socket_hook):
6184 * w32inevt.c (w32_console_read_socket):
6185 * w32term.c (w32_read_socket):
6186 * xterm.c (XTread_socket):
6187 Omit unused arg EXPECTED. All callers changed.
6188 (store_user_signal_events): Return void, not int, since callers no
6189 longer care about the return value. All uses changed.
6191 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6193 * w32gui.h (XParseGeometry): Do not declare.
6195 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6197 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6198 Ignore 'expected'. See Eli Zaretskii in
6199 <http://bugs.gnu.org/12471#8> (last line).
6201 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6202 (XParseGeometry): Now static. Substitute extremal values for
6203 values that are out of range.
6205 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6207 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6209 * nsfns.m (XParseGeometry): Remove.
6210 (Fx_create_frame): Call x_set_offset to correctly interpret
6211 top_pos in geometry.
6213 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6214 (Fx_parse_geometry): If there is a space in string, call
6215 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6217 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6219 * search.c (scan_buffer): Use character positions in calls to
6220 region_cache_forward and region_cache_backward, not byte
6221 positions. (Bug#12196)
6223 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6224 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6226 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6227 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6228 emacs_blocked_malloc, now deleted.
6230 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6232 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6233 The workaround was for improving performance on Solaris 2.4, but
6234 is getting in the way now. Emacs will still work if someone is
6235 still running Solaris 2.4 in a museum somewhere; Sun dropped
6236 support for Solaris 2.4 in 2003.
6237 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6238 * process.c (create_process) [HAVE_WORKING_VFORK]:
6239 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6240 since Emacs no longer uses vfork on that platform.
6242 2012-09-17 Glenn Morris <rgm@gnu.org>
6244 * emacs.c: Use COPYRIGHT.
6246 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6248 Remove configure's --without-sync-input option (Bug#12450).
6249 When auditing signal-handling in preparation for cleaning it up,
6250 I found that SYNC_INPUT has race conditions and would be a real
6251 pain to fix. Since it's an undocumented and deprecated
6252 configure-time option, now seems like a good time to remove it.
6253 Also see <http://bugs.gnu.org/11080#16>.
6254 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6255 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6256 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6257 (malloc_hysteresis):
6258 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6259 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6260 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6261 (dont_register_blocks, bytes_used_when_reconsidered)
6262 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6263 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6264 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6265 Remove. All uses removed.
6266 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6267 implementation, one that depends on whether the new macro
6268 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6270 * atimer.c (run_timers, handle_alarm_signal):
6271 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6272 (handle_async_input, process_pending_signals)
6273 (handle_input_available_signal, init_keyboard):
6274 * nsterm.m (ns_read_socket):
6275 * process.c (wait_reading_process_output):
6276 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6277 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6279 * xterm.c (XTread_socket):
6281 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6282 * eval.c (handling_signal): Remove. All uses removed.
6283 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6284 All uses replaced with the SYNC_INPUT version.
6285 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6287 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6290 * font.c (Ffont_shape_gstring): Remove unused local.
6292 2012-09-16 Glenn Morris <rgm@gnu.org>
6294 * Makefile.in (clean): No longer run nextstep's clean.
6296 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6298 (ns-app): Move here from ns.mk, and simplify.
6299 (clean): Simplify nextstep entry.
6300 * ns.mk: Remove file.
6302 2012-09-17 Kenichi Handa <handa@gnu.org>
6304 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6305 not covert the last few charactes.
6307 2012-09-16 Kenichi Handa <handa@gnu.org>
6309 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6310 here, but just check the validity of glyphs in the glyph-string.
6312 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6314 * window.c (Fwindow_parameter, Fset_window_parameter):
6315 Accept any window as argument (Bug#12452).
6317 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6319 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6320 to ns_term_init to avoid memory leak.
6322 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6323 explicit retain/release.
6324 (ns_term_init): Only allow one display. Initialize outerpool and
6327 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6329 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6330 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6331 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6332 the Microsoft problem in a different way, by altering ../nt/config.nt.
6334 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6349 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6350 by lisp.h. This completes removal of setjmp.h inclusion
6351 erroneously announced in the previous commit. (Bug#12446)
6353 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6356 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6357 not defined as a macro. The latter happens on MS-Windows.
6360 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6362 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6363 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6364 Some instances of '#include <setjmp.h>' removed, if the
6365 only reason for the instance was because "lisp.h" was included.
6366 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6367 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6368 and _longjmp with the new symbols. Emacs already uses _setjmp if
6369 available, so this change affects only POSIXish hosts that have
6370 sigsetjmp but not _setjmp, such as some versions of Solaris and
6371 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6372 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6373 (png_load_body) [HAVE_PNG]:
6374 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6375 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6376 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6377 since PNG requires jmp_buf. This is the only exception to the
6378 general rule that we now use sys_setjmp and sys_longjmp.
6379 This exception is OK since this code does not change the signal
6380 mask or longjmp out of a signal handler.
6382 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6384 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6385 Include "syssignal.h", for 'main_thread'.
6387 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6389 Avoid out-of-range marker position (Bug#12426).
6390 * insdel.c (replace_range, replace_range_2):
6391 Adjust markers before overlays, as suggested by comments.
6392 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6393 Remove redundant check before calling offset_intervals.
6395 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6397 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6398 current buffer (Bug#12387).
6400 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6402 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6404 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6406 Use a more backwards-compatible timer format (Bug#12430).
6407 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6408 vector element, not from the 4th, since PSECS is now at the end.
6409 (Fcurrent_idle_time): Doc fix.
6411 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6413 Function to mark objects and remove killed buffers at once.
6414 * alloc.c (discard_killed_buffers): Rename to ...
6415 (mark_discard_killed buffers) ... new name. Add marking
6416 of remaining objects. Fix comment. Adjust users.
6417 (mark_object): Do not touch frame buffer lists here.
6418 * frame.c (delete_frame): Reset frame buffer lists here.
6420 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6422 Better workaround for GNOME bug when --enable-gcc-warnings.
6423 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6424 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6425 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6427 Simplify SIGIO usage (Bug#12408).
6428 The code that dealt with SIGIO was crufty and confusing, e.g., it
6429 played tricks like "#undef SIGIO" but these tricks were not used
6430 consistently. Simplify mostly by not #undeffing standard symbols,
6431 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6432 or not as we please) rather than "defined SIGIO" (standard symbol
6433 that we probably shouldn't #undef).
6434 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6435 Modules that need it can include it.
6436 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6437 * dispextern.h (ignore_sigio): New decl.
6438 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6439 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6440 * emacs.c (shut_down_emacs):
6441 * keyboard.c (kbd_buffer_store_event_hold):
6442 Use ignore_sigio rather than invoking 'signal' directly.
6443 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6445 (FIONREAD, SIGIO): Do not #undef.
6446 (tty_read_avail_input): Use #error rather than a syntax error.
6447 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6448 for I_PIPE, used by SETUP_SLAVE_PTY.
6449 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6450 * sysdep.c (croak): Remove; no longer needed. This bit of
6451 temporary code, with Fred N. Fish's comment that it's temporary,
6452 has been in Emacs since at least 1992!
6453 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6454 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6455 * syssignal.h (croak): Remove decl.
6456 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6457 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6458 now that we're termios-only.
6459 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6460 * term.c (dissociate_if_controlling_tty): Use #error rather than
6463 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6464 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6465 to work around GNOME bug 683906.
6466 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6467 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6468 This works around GCC bug 54561.
6470 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6472 More fixes for 'volatile' and setjmp/longjmp.
6473 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6474 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6475 (png_load_body) [HAVE_PNG]:
6476 (jpeg_load_body) [HAVE_JPEG]:
6477 New function, with most of the old parent function's body.
6478 (png_load) [HAVE_PNG]:
6479 (jpeg_load) [HAVE_JPEG]:
6480 Invoke the new function, to avoid longjmp munging our locals.
6481 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6482 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6483 longjmp is passed 2, as the C standard doesn't guarantee this.
6484 Instead, store the failure code into mgr->failure_code.
6486 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6488 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6489 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6490 (syms_of_keyboard): Remove support for unread-command-char.
6492 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6494 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6495 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6496 violation. (Bug#12426)
6498 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6500 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6502 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6504 * eval.c: Add `inhibit-debugger'.
6505 (Qinhibit_debugger): New symbol.
6506 (call_debugger): Bind it instead of Qdebug_on_error.
6507 (maybe_call_debugger): Test Vinhibit_debugger.
6508 (syms_of_eval): Define inhibit-debugger.
6509 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6510 (syms_of_xdisp): Remove inhibit-debug-on-message.
6512 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6514 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6515 If a nonvolatile local variable is written before a _longjmp to
6516 the frame containing the variable, and is read after the _longjmp,
6517 the value read is indeterminate. Some local variables of type
6518 'struct handler' and 'struct catchtag' are used in this way, so
6519 mark each of their slots as volatile if the slot can be set before
6520 _longjmp and read afterwards.
6521 * lisp.h (struct handler): var and chosen_clause are now volatile.
6522 (struct catchtag): val, next, and pdlcount are now volatile.
6524 * bidi.c (bidi_push_it, bidi_pop_it):
6525 * fns.c (copy_hash_table):
6526 * image.c (define_image_type):
6527 * keyboard.c (kbd_buffer_store_event_hold):
6528 * process.c (Fprocess_send_eof):
6529 * xfaces.c (x_create_gc) [HAVE_NS]:
6530 * xgselect.c (xg_select):
6531 Prefer assignment to memcpy when either will do.
6533 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6534 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6535 time an item is removed. No need to mark this function 'inline';
6536 the compiler knows better than we do.
6538 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6540 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6541 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6542 to change_frame_size (Bug#12388).
6543 (windowDidResize:): Pass YES to updateFrameSize.
6545 * nsterm.h: Add delay parameter to updateFrameSize.
6547 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6549 Discard killed buffers from deleted window and frame objects.
6550 This reduces an amount of references to killed buffers and
6551 helps GC to reclaim them faster.
6552 * alloc.c (discard_killed_buffers): New function.
6553 (mark_object): Use it for deleted windows and frames.
6554 (mark_object): If symbol's value is set up for a killed buffer
6555 or deleted frame, restore its global binding.
6556 * data.c (swap_in_global_binding): Add GC notice.
6557 (swap_in_symval_forwarding): Use convenient set_blv_where.
6558 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6559 * window.h: ... to here.
6561 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6563 Convenient macro to check whether the buffer is live.
6564 * buffer.h (BUFFER_LIVE_P): New macro.
6565 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6566 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6568 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6570 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6571 composition cases (Bug#12364).
6573 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6574 overhang of succeeding glyphs overlapping box cursor.
6576 * w32term.c (x_draw_glyph_string): Likewise.
6578 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6580 Simplify, document, and port floating-point (Bug#12381).
6581 The porting part of this patch fixes bugs on non-IEEE platforms
6582 with frexp, ldexp, logb.
6583 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6585 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6586 support, by removing commented-out code and briefly listing the
6587 C89 functions excluded. The commented-out stuff was confusing
6588 maintenance, e.g., we thought we needed cbrt but it was commented out.
6589 (logb): Remove decl; no longer needed.
6590 (isfinite): New macro, if not already supplied.
6591 (isnan): Don't replace any existing macro.
6592 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6593 are present on all C89 platforms.
6594 (Ffrexp): Do not special-case zero, as frexp does the right thing
6596 (Flogb): Do not use logb, as it doesn't have the desired meaning
6597 on hosts that use non-base-2 floating point. Instead, stick with
6598 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6599 frexp, to avoid getting an unspecified result.
6601 * xdisp.c (Qinhibit_debug_on_message): Now static.
6603 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6605 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6606 NSBezierPath (Bug#12131).
6608 2012-09-10 Chong Yidong <cyd@gnu.org>
6610 * fns.c (Fdelq, Fdelete): Doc fix.
6612 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6614 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6615 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6617 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6619 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6620 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6623 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6625 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6626 left fringe if the window has a left margin. This avoids leaving
6627 traces of the cursor because its leftmost pixel is not drawn over.
6629 * dispnew.c (update_window_line): When the left margin area of a
6630 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6631 that screen line. (Bug#12277)
6633 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6635 Assume C89 or later for math functions (Bug#12381).
6636 This simplifies the code, and makes it a bit smaller and faster,
6637 and (most important) makes it easier to clean up signal handling
6638 since we can stop worring about floating-point exceptions in
6639 library code. That was a problem before C89, but the problem
6640 went away many years ago on all practical Emacs targets.
6641 * data.c, image.c, lread.c, print.c:
6642 Don't include <math.h>; no longer needed.
6643 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6644 might be autoconfigured, as that never happens.
6646 * doprnt.c (DBL_MAX_10_EXP):
6647 * print.c (DBL_DIG):
6648 Remove. C89 or later always defines these.
6649 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6650 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6651 (arith_error, domain_error, domain_error2):
6652 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6653 no longer needed -- we simply return what C returns. All uses removed.
6654 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6656 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6657 Remove. All uses expanded, as these macros are no longer used
6658 more than once and are now more trouble than they're worth.
6659 (Ftan): Use tan, not sin / cos.
6660 (Flogb): Assume C89 frexp.
6661 (fmod_float): Assume C89 fmod.
6662 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6663 (init_floatfns): Remove. All uses removed.
6665 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6667 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6668 compositeToPoint for OSX < 10.6 (Bug#12390).
6670 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6672 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6673 This produces more-accurate results.
6675 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6677 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6678 changes (Bug#12088).
6680 2012-09-08 Chong Yidong <cyd@gnu.org>
6682 * syntax.c (Fstring_to_syntax): Doc fix.
6684 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6686 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6687 in the internal border.
6688 (x_set_window_size): Remove static variables and their usage.
6689 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6690 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6691 Remove fringe/internal border adjustment (Bug#11052).
6692 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6693 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6694 (ns_fix_rect_ibw): Remove.
6695 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6696 (ns_dumpglyphs_box_or_relief): Ditto.
6697 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6699 (ns_dumpglyphs_image): Ditto.
6700 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6702 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6703 their usage. Add fringe_extended_p and its use as in other terms.
6704 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6705 scroll bar was removed.
6706 (updateFrameSize): New function.
6707 (windowDidResize): Move code to updateFrameSize and call it.
6709 * nsterm.h (EmacsView): Add updateFrameSize.
6711 2012-09-07 Chong Yidong <cyd@gnu.org>
6713 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6715 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6717 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6719 More signal-handler cleanup (Bug#12327).
6720 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6721 Problem introduced when merging patches. Noted by Eli Zaretskii in
6722 <http://bugs.gnu.org/12327#67>.
6723 * floatfns.c: Comment fix.
6724 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6725 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6726 and anyway the declaration is harmless even if SIGDANGER is not defined.
6727 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6728 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6729 source files not surprisingly expected syssignal.h to define, or
6730 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6731 Include <sys/ioctl.h>, for FIONREAD.
6732 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6733 This eliminates a problem whereby other files mysteriously had
6734 to include "syssignal.h" before including "systty.h" if they
6735 wanted to use "#ifdef SIGIO".
6737 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6739 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6741 * w32.c (sigemptyset): Empty the set.
6742 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6744 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6746 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6748 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6749 (mark_object): Likewise for frame objects.
6751 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6753 * syssignal.h (handle_on_main_thread): Always declare,
6754 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6755 This ports to platforms without HAVE_PTHREAD.
6757 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6759 Signal-handler cleanup (Bug#12327).
6760 Emacs's signal handlers were written in the old 4.2BSD style with
6761 sigblock and sigmask and so forth, and this led to some
6762 inefficiencies and confusion. Rewrite these to use
6763 pthread_sigmask etc. without copying signal sets around. Also,
6764 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6765 'signal', and instead use functions that do not attempt to take
6766 over the system name space. This patch causes Emacs's text
6767 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6768 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6769 Do not include <signal.h> or "syssignal.h", as these
6770 modules do not use signals.
6771 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6772 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6773 Do not include <signal.h>, as "syssignal.h" does that for us now.
6774 * atimer.c (sigmask_atimers): New function.
6775 (block_atimers, unblock_atimers): New functions,
6776 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6778 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6779 no longer needed here.
6780 * emacs.c (main): Inspect existing signal handler with sigaction,
6781 so that there's no need to block and unblock SIGHUP.
6782 * sysdep.c (struct save_signal): New member 'action', replacing
6783 old member 'handler'.
6784 (save_signal_handlers, restore_signal_handlers):
6785 Use sigaction instead of 'signal' to save and restore.
6786 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6787 New function. All users of 'signal' modified to use set_sighandler
6788 if they're writeonly, and to use sys_signal if they're read+write.
6789 (emacs_sigaction_init, forwarded_signal): New functions.
6790 (sys_signal): Remove. All uses replaced by calls to sigaction
6791 and emacs_sigaction_init, or by direct calls to 'signal'.
6792 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6793 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6794 all uses replaced by pthread_sigmask etc. calls.
6795 * syssignal.h: Include <signal.h>.
6796 (emacs_sigaction_init, forwarded_signal): New decls.
6797 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6798 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6799 (sigmask, sys_sigmask): Remove; no longer needed.
6800 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6801 (sigblock, sigunblock, sigfree):
6802 (sigsetmask) [!defined sigsetmask]:
6803 Remove. All uses replaced by pthread_sigmask.
6804 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6805 no longer need to be replaced, and its typical old uses
6806 are now done via emacs_sigaction_init and sigaction.
6807 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6808 (sys_sigdel): Remove; unused.
6809 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6811 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6813 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6814 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6816 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6818 Explicitly mark buffer_defaults and buffer_local_symbols.
6819 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6820 mark_local_symbols here.
6821 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6822 since special buffers aren't marked here any more.
6823 (allocate_buffer): Chain new buffer with all_buffers here...
6824 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6826 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6827 (syms_of_buffer): Remove staticpro of the above.
6828 (init_buffer_once): Set names for buffer_defaults and
6829 buffer_local_symbols.
6831 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6833 Use bool for booleans in font-related modules.
6834 * font.c (font_intern_prop, font_style_to_value)
6835 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6836 (generate_otf_features, font_check_otf_features, font_check_otf)
6837 (font_match_p, font_list_entities, font_at):
6838 * fontset.c (fontset_id_valid_p, reorder_font_vector
6839 (fontset_find_font, Fset_fontset_font)
6840 (face_suitable_for_char_p) [0]:
6841 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6842 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6843 (m17n_flt_initialized, ftfont_shape_by_flt):
6844 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6845 * nsfont.m (nsfont_draw):
6846 * w32font.c (w32font_draw):
6847 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6848 Use bool for booleans.
6849 * font.h: Adjust to above API changes.
6850 (struct font, struct font_driver, struct font_driver_list):
6851 Use bool for booleans.
6852 (struct font): Remove useless member encoding_type.
6854 * fontset.c, xftfont.c: Omit unnecessary static decls.
6856 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6858 * alloc.c (mark_object): Revert window marking code
6859 since it's unsafe for the Fset_window_configuration.
6861 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6863 Fix race conditions with signal handlers and errno (Bug#12327).
6864 Be more systematic about preserving errno whenever a signal
6865 handler returns, even if it's not in the main thread. Do this by
6866 renaming signal handlers to distinguish between signal delivery
6867 and signal handling. All uses changed.
6868 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6869 * data.c (deliver_arith_signal): Rename from arith_error.
6870 * dispnew.c (deliver_window_change_signal): Rename from
6871 window_change_signal.
6872 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6873 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6874 * keyboard.c (deliver_input_available_signal): Rename from
6875 input_available_signal.
6876 (deliver_user_signal): Rename from handle_user_signal.
6877 (deliver_interrupt_signal): Rename from interrupt_signal.
6878 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6879 (deliver_child_signal): Rename from sigchld_handler.
6880 * atimer.c (handle_alarm_signal):
6881 * data.c (handle_arith_signal):
6882 * dispnew.c (handle_window_change_signal):
6883 * emacs.c (handle_fatal_signal, handle_danger_signal):
6884 * keyboard.c (handle_input_available_signal):
6885 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6886 * process.c (handle_pipe_signal, handle_child_signal):
6887 New functions, with the actual signal-handling code taken from the
6888 original respective signal handlers, sans the sporadic attempts to
6889 preserve errno, since that's now done by handle_on_main_thread.
6890 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6891 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6892 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6894 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6895 Move initialization of main_thread to sysdep.c's init_signals.
6896 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6897 our usage, and simplifies the mainline code.
6898 (record_child_status_change): New static function, as a helper
6899 for handle_child_signal, and with most of the old child handler's
6901 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6902 (handle_child_signal): Use the above.
6903 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6904 Moved here from emacs.c.
6905 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6906 code moved here from emacs.c's main function.
6907 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6908 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6909 This lets callers save and restore errno properly.
6911 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6913 Remove redundant or unused things here and there.
6914 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6915 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6916 * editfns.c (Fcompare_buffer_substrings): Likewise.
6917 * frame.h (struct terminal, struct font_driver_list):
6918 Remove redundant declarations.
6919 * window.h (Qleft, Qright): Likewise.
6921 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6923 Do not mark objects from deleted buffers, windows and frames.
6924 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6925 (mark_object): Likewise for windows and frames.
6927 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6929 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6930 buffer_defaults and buffer_local_symbols as valid objects.
6931 Return special value to denote them.
6933 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6935 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6936 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6937 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6938 (file_name_absolute_p, Fsubstitute_in_file_name):
6939 (check_executable, check_writable, Ffile_accessible_directory_p)
6940 (Fset_file_selinux_context, Fdefault_file_modes)
6941 (Finsert_file_contents, choose_write_coding_system)
6942 (Fwrite_region, build_annotations, a_write, e_write)
6944 * filelock.c (boot_time_initialized, get_boot_time)
6945 (get_boot_time_1, lock_file_1, within_one_second):
6946 * floatfns.c (in_float):
6947 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6948 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6949 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6950 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6951 * window.c (compare_window_configurations):
6952 Use bool for booleans.
6953 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6954 (Fdefault_file_modes): Now mode_t, not int, for modes.
6955 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6956 (internal_delete_file): Now returns void, not a (boolean) int,
6957 since nobody was looking at the return value.
6958 * lisp.h, window.h: Adjust to above API changes.
6960 * xdisp.c (set_message): Simplify and reindent last change.
6962 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6964 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6966 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6968 * eval.c (call_debugger): Make the function non-static so that we
6969 can call it from set_message.
6971 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6972 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6974 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6976 Give more-useful info on a fatal error (Bug#12328).
6977 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6978 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6979 of doing the work ourselves.
6980 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6981 do most of the work.
6982 (fatal_error_backtrace): New function, taken from the guts
6983 of the old fatal_error_signal, but with a new option to output
6985 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6986 info about the signal than just its number.
6987 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6988 * sysdep.c: Include <execinfo.h>
6989 (emacs_backtrace): New function, taken partly from the previous
6990 code of the 'die' function.
6991 (emacs_abort): Call fatal_error_backtrace rather than abort.
6993 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6995 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6996 eager (load-time) macro-expansion.
6997 * lisp.mk (lisp): Add macroexp.
6999 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7001 Simplify redefinition of 'abort' (Bug#12316).
7002 Do not try to redefine the 'abort' function. Instead, redo
7003 the code so that it calls 'emacs_abort' rather than 'abort'.
7004 This removes the need for the NO_ABORT configure-time macro
7005 and makes it easier to change the abort code to do a backtrace.
7006 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7007 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7008 Remove; sysdep.c's emacs_abort now takes its place.
7009 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7010 'abort' changed to use 'emacs_abort'.
7011 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7012 (abort) [!defined abort]: Rename to ...
7013 (emacs_abort): ... new name.
7014 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7015 the place of the old 'abort' in emacs.c.
7016 * w32.c, w32fns.c (abort): Do not #undef.
7017 * w32.c (emacs_abort): Rename from w32_abort.
7019 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7021 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7022 offsets[j].dv, since the y axis of the screen coordinates points
7023 down, while the y axis of the font definition coordinates points
7024 up. This fixes display of Arabic diacritics such as KASRA and
7025 KASRATAN. (Bug#11860)
7027 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7029 Be more systematic about _setjmp vs setjmp.
7030 * alloc.c (test_setjmp, mark_stack):
7031 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7032 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7033 (png_load, my_error_exit, jpeg_load):
7034 * process.c (send_process_trap, send_process):
7035 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7036 The underscored versions are up to 30x faster on some hosts.
7037 Formerly, the code used setjmp+longjmp sometimes and
7038 _setjmp+_longjmp at other times, with no particular reason to
7039 prefer setjmp+longjmp.
7041 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7043 Fix minor problem found by static checking.
7044 * buffer.c (Fdelete_all_overlays): Return nil.
7046 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7048 * buffer.c (Fdelete_all_overlays): New function.
7050 2012-09-03 Chong Yidong <cyd@gnu.org>
7052 * gtkutil.c: Add extern decl for Qxft.
7054 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
7056 * emacs.c, eval.c: Use bool for boolean.
7057 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
7058 (malloc_using_checking) [DOUG_LEA_MALLOC]:
7059 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
7060 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
7061 (main, decode_env_path, Fdaemon_initialized):
7062 * eval.c (call_debugger, Finteractive_p, interactive_p):
7063 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
7064 (maybe_call_debugger, Fbacktrace):
7065 * process.c (read_process_output, exec_sentinel):
7066 Use bool for booleans.
7067 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
7068 All callers changed.
7069 * eval.c (interactive_p): Omit always-true boolean argument
7070 EXCLUDE_SUBRS_P. All callers changed.
7071 * dispextern.h, lisp.h: Reflect above API changes.
7072 * firstfile.c (dummy): Use the address of 'main', whose signature
7073 won't change, instead of the address of 'initialize', whose
7074 signature just changed from int to bool.
7075 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7076 * msdos.c (fatal_error_in_progress): ... from here.
7077 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7079 (redisplay_internal, unwind_redisplay): Simply clear
7080 REDISPLAYING_P when unwinding, instead of saving its previous,
7081 always-false value and then restoring it.
7083 Clean up some extern decls.
7084 Mostly, this hoists extern decls out of .c files and into .h files.
7085 That way, we're more likely to catch errors if the interfaces change.
7086 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7087 declare xg_mark_data.
7088 * dispextern.h (x_frame_parm_handlers):
7090 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
7091 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
7092 (Qultra_bold, Qoblique, Qitalic):
7093 Move extern decl here from .c file.
7094 * alloc.c (xg_mark_data) [USE_GTK]:
7096 * eval.c (Qlexical_binding):
7097 * fns.c (time) [!HAVE_UNISTD_H]:
7098 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
7099 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):

7103 * process.c (QCfamily, QCfilter):
7104 * widget.c (free_frame_faces):
7105 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
7106 * xfont.c (x_clear_errors):
7107 * xterm.c (x_frame_parm_handlers):
7108 Remove now-redundant extern decls.
7109 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7110 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7112 * xfaces.c: Remove unnecessary static decls.
7113 * xterm.c (updating_frame): Remove decl of nonexistent object.
7115 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7116 when building globals.h, as the objects that are not built on
7117 this host are not needed to compile C files on this host.
7119 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
7121 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
7123 * frame.h: Add missing prototype for x_wm_set_size_hint.
7125 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

7129 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
7130 (Fsubstitute_command_keys):

7133 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)
7134 (format_time_string, general_insert_function)
7135 (make_buffer_string, make_buffer_string_both)
7136 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

7146 (adjust_for_invis_intang, set_point_both)

7148 (set_intervals_multibyte_1, set_intervals_multibyte):
7149 * keyboard.c (decode_timer):
7150 Use bool for boolean.
7151 * intervals.h, lisp.h, systime.h: Reflect above API changes.

7154 2012-09-02 Chong Yidong <cyd@gnu.org>
7156 * keymap.c (push_key_description): Print M-TAB as C-M-i
7159 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
7161 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
7162 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

7167 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
7169 2012-09-01 Eli Zaretskii <eliz@gnu.org>
7171 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7172 more than one grapheme cluster passed to the shaper: compute the
7173 offset adjustment values separately for each cluster. (Bug#11860)
7175 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7176 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7177 about implicit conversions from integer to pointer.
7179 2012-09-01 Daniel Colascione <dancol@dancol.org>
7181 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7182 system used too early.
7184 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
7186 Better seed support for (random).
7187 * emacs.c (main): Call init_random.
7188 * fns.c (Frandom): Set the seed from a string argument, if given.
7189 Remove long-obsolete Gentzel cruft.

7196 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
7197 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,

7199 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
7200 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
7201 all of which have been moved to common code.
7203 * xfaces.c: Include TERM_HEADER instead of listing all possible
7204 window-system headers.
7206 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

7210 directly accessing frame internals.
7212 * w32font.h: Include font.h. Define syms_of_w32font and
7215 * process.c: Include TERM_HEADER instead of listing all possible
7216 window-system headers.
7218 * nsterm.h: Remove declarations now in frame.h.
7219 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
7221 * menu.c: Include TERM_HEADER instead of listing all possible
7222 window-system headers.
7224 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
7227 * keyboard.c: Include TERM_HEADER instead of listing all possible
7228 window-system headers.
7230 * image.c: Include TERM_HEADER instead of listing all possible
7231 window-system headers. Declare Vlibrary_cache when compiling for
7234 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
7235 window system declarations.
7237 * frame.h: Move common functions here: set_frame_menubar,
7238 x_set_window_size, x_sync, x_get_focus_frame,
7239 x_set_mouse_position, x_set_mouse_pixel_position,
7240 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

7260 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
7261 the current window system; include in list of objects to link into
7264 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7266 Remove mark_ttys function and fix tty_display_info initialization.
7267 * lisp.h (mark_ttys): Remove prototype.
7268 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
7269 to mark_ttys because all possible values of 'top_frame' slot are
7270 the frames which are reachable from Vframe_list.
7271 * term.c (mark_ttys): Remove.
7272 (init_tty): Safely initialize 'top_frame' slot with Qnil.
7274 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7276 Change struct frame bitfields from unsigned char to unsigned.
7277 * frame.h (struct frame): Change type of 'display_preempted',
7278 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
7279 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
7280 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
7281 bitfields from unsigned char to unsigned.
7283 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7285 Remove unused member of struct x_output and struct w32_output.
7286 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
7287 * w32term.h (struct w32_output): Likewise.
7289 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
7291 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
7292 does not become zero (Bug#12234).
7294 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
7296 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
7297 for GCC 4.7.1 x86-64.
7299 2012-08-30 Glenn Morris <rgm@gnu.org>
7301 * lread.c (init_lread): For out-of-tree builds, only add the
7302 source directory's site-lisp dir to the load-path if it exists,
7303 consistent with in-tree builds. (Bug#12302)
7305 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
7307 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
7308 button_values to NULL. Call setStykeMask so dialogs get a close button.
7309 (windowShouldClose:): Set window_closed.
7310 (dealloc): New member, free button_values.
7311 (process_dialog:): Make member function. Remove window argument,
7312 replace window with self. Count buttons and allocate and store values
7314 (addButton:value:row:): value is int with the name tag. Call setTag
7315 with tag. Remove return self, declare return value as void.
7316 (addString:row:): Remove return self, declare return value as void.
7317 (addSplit): Remove return self, declare return value as void.
7318 (clicked:): Remove return self, declare return value as void.
7319 Set dialog_return to button_values[seltag]. Code formatting change.
7320 (initFromContents:isQuestion:): Adjust call to process_dialog.
7321 Code formatting change.
7322 (timeout_handler:): Set timer_fired to YES.
7323 (runDialogAt:): Set timer_fired to NO.
7324 Handle click on close button as quit.
7326 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7327 Add window_closed and button_values. Add void as return value for
7328 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7329 Add process_dialog as new member.
7331 2012-08-28 Eli Zaretskii <eliz@gnu.org>
7333 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
7334 is not one of the heaps we manage. (Bug#12242)
7336 2012-08-28 Glenn Morris <rgm@gnu.org>
7338 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
7340 2012-08-28 Martin Rudalics <rudalics@gmx.at>
7342 * window.c (Fset_window_configuration): Remove handling of
7343 auto-buffer-name window parameter. Install revision of reverted

7349 * buffer.c (Fset_buffer_major_mode): Signal an error
7350 if the buffer is dead.
7351 (Fother_buffer, other_buffer_safely): Remove redundant
7354 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
7356 Always use set_buffer_if_live to restore original buffer at unwind.
7357 * buffer.h (record_unwind_current_buffer): New function.
7358 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:

7361 * buffer.c (set_buffer_if_live): Fix comment.
7363 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
7365 Fix usage of set_buffer_internal.
7366 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
7367 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
7368 * coding.c (decode_coding): Omit redundant test.
7369 * fileio.c (decide_coding_unwind): Likewise.
7370 * fns.c (secure_hash): Likewise.

7396 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
7397 and remove last int (actually boolean) argument, which was always 0.
7398 All callers changed.
7399 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
7400 * dispextern.h (struct composition_it): Use bool for boolean.
7401 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
7402 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
7403 * dired.c (file_name_completion):
7404 Use bool for boolean. (This was missed in an earlier change.)
7406 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7408 * window.c (Fset_window_configuration): Revert first part of
7411 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
7413 * nsterm.h (NSPanel): New class variable dialog_return.
7415 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
7416 Initialize dialog_return.
7417 (windowShouldClose:): Use stop instead of stopModalWithCode.
7418 (clicked:): Ditto, and also set dialog_return (Bug#12258).
7419 (timeout_handler:): Use stop instead of abortModal. Send a dummy
7421 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

7466 Use bool for booleans.
7467 * coding.h, lisp.h: Reflect above API changes.
7468 * coding.c: Remove unnecessary static function decls.
7469 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
7470 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
7471 not a boolean 'int', since callers never look at the return value.
7472 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
7473 * coding.h (decoding_buffer_size, encoding_buffer_size)
7474 (emacs_mule_string_char): Remove unused extern decls.
7475 (struct iso_2022_spec, struct coding_system):

7478 All initializations removed.

7481 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7483 Fix spare memory change (Bug#12286).
7484 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7485 (valid_lisp_object_p): Likewise.
7487 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7489 * window.c (Fset_window_configuration): Record any window's old
7490 buffer if it's replaced (see Bug#8789). If the new current
7491 buffer doesn't appear in the selected window, go to its old
7494 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7496 Special MEM_TYPE_SPARE to denote reserved memory.
7497 * alloc.c (enum mem_type): New memory type.
7498 (refill_memory_reserve): Use new type for spare memory.
7499 This prevents live_cons_p and live_string_p from incorrect
7500 detection of uninitialized objects from spare memory as live.
7502 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7505 * Makefile.in (.PHONY): versioclean -> versionclean.
7507 Remove unused external symbols.
7508 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7509 * window.c (Qwindow_valid_p, decode_valid_window):
7510 Now static, not extern.
7511 * data.c (Qinterval): Remove; unused.
7512 (syms_of_data): Do not define 'interval'.
7513 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7514 * window.h (decode_valid_window):
7517 * character.c, charset.c, chartab.c: Use bool for booleans.

7528 (map_sub_char_table):
7529 Use bool for boolean.
7530 * character.c (str_to_unibyte): Omit last boolean argument; it was
7531 always 0. All callers changed.
7532 * character.h, charset.h: Adjust to match previous changes.
7533 * character.h (char_printable_p): Remove decl of nonexistent function.
7534 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7535 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7536 are all boolean, so make them single-bit bitfields.
7538 * lisp.h (ASET): Remove attempt to detect side effects.
7539 It was meant to be temporary and it often doesn't work,
7540 because when IDX has side effects the behavior of IDX==IDX
7541 is undefined. See Stefan Monnier in
7542 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7544 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7546 * lisp.h (functionp): New function (extracted from Ffunctionp).
7547 (FUNCTIONP): Use it.
7548 * eval.c (Ffunctionp): Use it.
7550 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7552 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7553 as that's faster and simpler than static storage. Don't bother
7554 with the g_main_context_query overhead if g_main_context_pending
7555 says no events are pending.
7556 (gfds, gfds_size): Remove these static vars.
7557 (xgselect_initialize): Remove; no longer needed.
7558 All uses and decls removed.
7560 * emacs.c (fatal_error_signal_hook): Remove.
7561 All uses removed. This leftover from old code was always 0.
7563 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7564 * casefiddle.c (casify_object, casify_region):
7565 * casetab.c (set_case_table):
7566 * category.c, category.h (word_boundary_p):
7567 * category.h (CHAR_HAS_CATEGORY):
7568 Use bool for booleans, instead of int.
7570 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7572 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7574 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7576 On assertion failure, print backtrace if available.
7577 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7578 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7579 * Makefile.in (LIB_EXECINFO): New macro.
7582 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7583 * bytecode.c (exec_byte_code):
7584 * callint.c (check_mark, Fcall_interactively):
7585 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7586 (getenv_internal, sync_process_alive, call_process_exited):
7587 * lisp.h (USE_SAFE_ALLOCA):
7588 Use bool for booleans, instead of int.
7589 * lisp.h, process.h: Adjust prototypes to match above changes.
7590 * callint.c (Fcall_interactively): Don't assume the mark's
7591 offset fits in 'int'.
7593 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7595 * buffer.c, buffer.h: Use bool for boolean.

7602 (mmap_enlarge, mmap_set_vars):
7603 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7604 Use bool for booleans, instead of int.
7605 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7606 since the 1-or-0 return value is always ignored anyway.
7607 (mmap_initialized_p):
7608 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7609 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7611 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7613 * bidi.c: Use bool for boolean.
7614 This is a bit more readable, and makes the text segment of bidi.o
7615 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7616 Presumably it's faster too.
7617 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

7622 (bidi_explicit_dir_char, bidi_level_of_next_char)
7623 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7624 Use bool for booleans, instead of int.
7625 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7626 (bidi_unshelve_cache): Adjust decls to match code.
7628 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7630 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7633 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7635 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7636 * atimer.h: Include <stdbool.h>.
7638 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7640 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7641 compile time tests instead of run time tests on systems that do
7643 (FRAME_MAC_P): Remove leftover from deleted code.
7644 * frame.c (syms_of_frame): Remove leftover from deleted code.
7646 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7648 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7650 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7652 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7653 Otherwise, the compiler complains about (A?B:C) where B is void
7654 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7655 (fontset_add): Return void, for FONTSET_ADD.
7657 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7659 * alloc.c: Use bool for booleans.
7660 (gc_in_progress, abort_on_gc)
7661 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7662 (dont_register_blocks) [GC_MALLOC_CHECK]:

7666 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7667 (mark_stack, valid_pointer_p, make_pure_string)
7668 (Fgarbage_collect, survives_gc_p, gc_sweep):
7669 Use bool for booleans, instead of int.
7670 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7671 Remove unused local.
7672 * alloc.c (PURE_POINTER_P):
7673 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7674 * editfns.c (Fformat):
7675 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7677 * fns.c (sweep_weak_table):
7678 * lisp.h (suppress_checking, push_message, survives_gc_p)
7679 (make_pure_string, gc_in_progress, abort_on_gc):
7680 * lread.c (readchar, read1):
7681 * print.c (Fprin1_to_string):
7682 * xdisp.c (push_message):
7683 Use bool for booleans affected directly or indirectly by
7686 Make recently-introduced setters macros.
7687 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7688 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7689 (set_fontset_default, set_fontset_fallback): Rename from their
7690 upper-case counterparts, and make them functions rather than macros.
7691 This is more consistent with the other recently-introduced setters.
7692 These don't need to be inline, since they're local.
7694 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7696 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7697 the loop (Bug#12247).
7699 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7701 * lisp.h (vcopy): Use memcpy rather than our own loop.
7702 This fixes a performance regression introduced by the recent
7703 addition of vcopy. This means 'vcopy' will need to be modified
7704 for a copying collector, but that's OK. Also, tighten the
7705 checking in the assertion.
7707 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7709 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7710 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7711 non-base glyph for the width of the base character, according to
7712 what x_draw_composite_glyph_string_foreground expects.
7713 Generate WADJUST value according to composition_gstring_width's
7714 expectations, to produce correct width of the composed character.
7715 Reverse the sign of the DU offset produced by ScriptPlace.
7717 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7719 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7721 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7723 Avoid direct writes to contents member of struct Lisp_Vector.

7801 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7803 Rely on <config.h> + <unistd.h> to declare 'environ',
7804 as gnulib does this if the system doesn't.
7805 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

8674 2012-08-04 Eli Zaretskii <eliz@gnu.org>
8676 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
8677 * w32.c (init_environment): Change the default values of many
8678 environment variables in dflt_envvars[] to NULL, to avoid pushing
8679 them into environment when they were not already defined.
8680 Remove the code that deletes site-lisp subdirectories from the default
8681 value of EMACSLOADPATH, as it is no longer needed.
8682 (check_windows_init_file): Now external, not static.
8683 Use Vload_path as is, without adding anything, as this function is now
8684 called when Vload_path is already set up.
8686 * w32.h (check_windows_init_file): Add prototype.
8688 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
8689 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
8690 compatibility with Posix platforms.
8691 (main): Move the call to check_windows_init_file to here from
8693 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
8694 any, in the DEFALT argument into the root of the Emacs build or
8695 installation tree, as appropriate.
8697 * callproc.c (init_callproc_1): Call decode_env_path instead of
8698 doing its equivalent by hand.
8699 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
8700 the code that sets Vexec_path run on MS-Windows.
8702 * lread.c (init_lread): Add comments to #ifdef's.
8704 * msdos.c (dos_set_window_size, IT_update_begin)

8712 Now constants, not macros.
8714 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
8716 Remove unnecessary casts involving pointers.
8717 These casts are no longer needed now that we assume C89 or later,
8718 since they involve casting to or from void *.

8720 (make_pure_float, make_pure_vector):
8721 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

8731 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8732 Remove unnecessary pointer casts.
8733 * alloc.c (record_xmalloc): New function.
8734 * lisp.h (record_xmalloc): New decl.
8735 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8736 more like a function. This is because the pointer cast is not
8737 needed. All uses changed.
8738 * print.c (print_string, print_error_message): Avoid length recalc.
8740 Improve fix for macroexp crash with debugging (Bug#12118).
8741 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8742 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8743 not supposed to be invoked from the garbage collector.
8744 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
8745 (gc_aset): New function, which is like ASET but can be
8746 used in the garbage collector.
8747 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

8760 (map_w32_filename): Improve commentary. Simplify switch.
8761 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
8762 headers (most versions of MinGW w32api don't).
8763 (get_security_info, create_symbolic_link)
8764 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
8766 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
8767 in the argument file name.

8770 (sys_rename): Diagnose renaming of a symlink when the user doesn't
8771 have the required privileges.
8772 (get_file_security_desc_by_name): Rename from
8773 get_file_security_desc.
8774 (stat_worker): New function, with most of the guts of 'stat', and
8775 with addition of handling of symlinks and support for 'lstat'.
8776 If possible, get file's attributes and security information by
8777 handle, not by name. Produce S_IFLNK bit for symlinks, when
8778 called from 'lstat'.
8779 (stat, lstat): New functions, call 'stat_worker'.
8780 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8781 symlinks when the underlying filesystem supports them.
8783 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8785 Fix macroexp crash on Windows with debugging (Bug#12118).
8786 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8787 checking subscripts; problem introduced with the recent
8788 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8789 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8790 since it's used in non-static inline functions now.
8792 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8793 Don't assume buffer size fits in 'int'. Remove unused local.

8810 * category.c (CATEGORY_INLINE):
8811 * character.c (CHARACTER_INLINE):
8812 * charset.c (CHARSET_INLINE):
8813 * composite.c (COMPOSITE_INLINE):
8814 * dispnew.c (DISPEXTERN_INLINE):
8815 * sysdep.c (SYSTIME_INLINE):
8816 Define to EXTERN_INLINE, so that the corresponding functions
8817 are compiled into code.
8818 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8819 (INLINE_HEADER_END): New macros.
8820 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8840 hard-coding the path separator.
8842 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8844 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8845 This how ASET and AREF are supposed to work, and makes
8846 it easier to think about future improvements. See
8847 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8848 * charset.h (set_charset_attr): New function.

9101 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
9102 does that unconditionally. Remove file, which is now empty.
9104 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
9107 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

9225 * w32inevt.c: Include w32inevt.h.
9226 (w32_read_console_input): New inline function, calls either
9227 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
9228 w32_console_unicode_input.
9229 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
9230 (w32_kbd_patch_key, key_event): Use the codepage returned by
9231 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

9260 * alloc.c (listn): Fix the order the arguments are consed onto the
9263 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
9264 enumeration constants, as PURE and HEAP are too general, and clash
9265 with other headers and sources, such as gmalloc.c and the
9266 MS-Windows system headers. All users changed.
9268 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9270 Revert last save_excursion_save and save_excursion_restore changes.
9271 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

9281 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
9283 Improve GDB symbol export (Bug#12036).
9284 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
9285 arms of an 'if', not using conditional expressions; otherwise GDB
9286 complains about the types in the unevaluated arm when the argument
9287 is an integer literal.
9288 (xgetint): Simplify expression.
9289 * alloc.c (gdb_make_enums_visible): New constant. This ports to
9290 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
9291 Zaretskii in <http://bugs.gnu.org/12036#13>.
9292 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
9293 needed now that we have gdb_make_enums_visible.
9294 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
9295 (enum enum_USE_LSB_TAG):
9296 New enum types, packaging up enums that need to be exported to GDB.

9314 * xdisp.c (syms_of_xdisp): Likewise.
9315 * xfns.c (syms_of_xfns): Likewise.
9317 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9319 Fast save_excursion_save and save_excursion_restore.
9320 * lisp.h (struct Lisp_Excursion): New data type.
9321 (PVEC_EXCURSION): New pseudovector type.
9322 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
9323 to deal with it. Adjust comments.
9324 (init_marker, attach_marker): New prototype.
9325 (unchain_marker): Adjust prototype.

9334 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9336 Fix export of symbols to GDB (Bug#12036).
9337 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
9338 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9339 emacs.c, as this is a more-suitable home. Had this been done earlier
9340 the fix for 12036 would have avoided some of the problems noted in
9341 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9342 would have been more obvious.
9343 * emacs.c: Do not include <verify.h>; no longer needed.
9344 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9345 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9346 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9347 Remove; now done in lisp.h.

9351 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
9352 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9353 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9354 not be usable in #if. This simplifies things.
9356 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9358 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9360 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

9363 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9364 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9365 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9366 Adjust to changes in lisp.h and emacs.c, by using
9367 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9368 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9369 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9370 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9371 instead of gdb_valbits.
9372 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9373 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9374 instead of gdb_array_mark_flag.
9375 (xboolvector): Get size from $->size, not $->header.size.
9376 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9377 (xreload, hook-run, hookpost-run): Remove.
9378 * emacs.c: Include <verify.h>.
9379 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9380 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9382 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9383 (gdb_USE_LSB_TAG): New enum constants.
9384 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9385 Also define these as enum constants, so they're visible to GDB.
9386 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9387 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9388 as constants, so they're visible to GDB.
9389 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
9390 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9391 Now enum constants, not macros, so they're visible to GDB.
9392 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9393 more convenient now. All uses changed.
9394 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9395 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9397 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
9399 Explicitly free restriction data that are not needed anymore.
9400 * editfns.c (save_restriction_restore): Free restriction data.
9402 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
9404 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9405 add argument, tune behavior, and adjust all callers.
9407 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9409 Use typedef for EMACS_INT, EMACS_UINT.
9410 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9411 than macros. This simplifies debugging in the usual case, since
9412 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9413 and it allows expressions involving EMACS_INT casts.
9414 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9416 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
9418 * nsterm.m (ns_read_socket): Return early if there is a modal
9421 2012-07-25 Martin Rudalics <rudalics@gmx.at>

9424 that FOCUS-FRAME can be omitted.
9426 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9428 Adjust buffer text indirection counters at the end of Fkill_buffer.
9429 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9430 buffer is definitely dead. This should really fix an issue reported
9431 by Christoph Scholtes again. (Bug#12007).
9432 (init_buffer_once): Initialize indirection counters of
9433 buffer_defaults and buffer_local_symbols (for sanity and safety).
9435 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9437 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9438 and continuation glyphs on tooltip frames, leave them at zero.
9439 Avoids continued lines in tooltips. (Bug#11832)
9441 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
9443 Simplify copy_overlay.
9444 * buffer.c (copy_overlay): Simplify. Use build_marker.

9450 or invalid. (Bug#12025)
9452 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
9453 it signals an error when a tooltip frame is being created.
9455 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9457 Cleanup miscellaneous objects allocation and initialization.
9458 * alloc.c (allocate_misc): Change to static. Add argument to
9459 specify the subtype. Adjust comment and users.
9460 (build_overlay): New function.
9461 * buffer.c (copy_overlays, Fmake_overlay): Use it.
9462 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
9463 (allocate_misc): Remove prototype.
9464 (build_overlay): Add prototype.
9466 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9468 Swap buffer text indirection counters in Fbuffer_swap_text.
9469 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9470 This avoids crash reported by Christoph Scholtes at
9471 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9473 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9475 * nsmenu.m (Popdown_data): New struct.

10229 * s/aix4-2.h (unix): Remove; no longer needed.
10231 EMACS_TIME simplification (Bug#11875).
10232 This replaces macros (which typically do not work in GDB)

10234 The functional style also makes code easier to read and maintain.
10235 * systime.h: Include <sys/time.h> on all hosts, not just if
10236 WINDOWSNT, since 'struct timeval' is needed in general.
10237 (EMACS_TIME): Now a typedef, not a macro.

10271 (menu_separator_name_p):
10272 * nsmenu.m (ns_update_menubar):
10273 Prefer memcmp to strncmp when either will do.
10274 * nsterm.m: Include <ftoastr.h>.
10276 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10277 Prefer snprintf to strncpy.
10278 * nsterm.m (ns_term_init):
10279 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10280 * nsterm.m (ns_term_init):
10281 Avoid the need for strncpy, by using build_string or
10282 make_unibyte_string directly. Use dtoastr, not snprintf.
10283 * process.c (Fmake_network_process): Diagnose service names that
10284 are too long, rather than silently truncating them or creating
10285 non-null-terminated names.
10286 (Fnetwork_interface_info): Likewise, for interface names.
10287 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10288 Prefer sprintf to strncat.

10301 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10302 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

10317 (build_pure_c_string): New function, defined as static inline. This
10318 provides a better opportunity to optimize away calls to strlen when
10319 the function is called with compile-time constant argument.
10320 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10321 argument, adjust users accordingly. Use build_pure_c_string where

10324 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10325 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

10352 * s/gnu.h (DATA_START): Move definitions to configure.
10354 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10355 We include usg5-4-common.h, which defines them both.
10357 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10358 O_RDONLY already includes it).
10360 Stop ns builds setting the EMACSLOADPATH environment variable.
10361 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10362 Now it does not set EMACSLOADPATH, just returns the load-path string.
10363 * nsterm.h: Update accordingly.
10364 * lread.c [HAVE_NS]: Include nsterm.h.
10365 (init_lread) [HAVE_NS]: Use ns_load_path.
10366 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10368 2012-07-09 Glenn Morris <rgm@gnu.org>
10370 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10371 since the included bsd-common.h does so.
10373 Stop ns builds setting the EMACSPATH environment variable.
10374 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10375 (ns_init_paths): Do not set EMACSPATH.
10376 * nsterm.h (ns_exec_path): Add it.
10377 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10380 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10382 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10384 * process.c (wait_reading_process_output): 'waitchannels' was unset
10385 when read_kbd || !NILP (wait_for_cell); fix this.
10387 Add GCC-style 'const' attribute to functions that can use it.
10388 * character.h (char_resolve_modifier_mask):
10389 * keyboard.h (make_ctrl_char):
10390 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10391 (init_character_once, next_almost_prime, init_fns, init_image)
10392 (flush_pending_output, init_sound):
10393 * mem-limits.h (start_of_data):

10399 Add decls with ATTRIBUTE_CONST.
10401 Minor improvements to make_formatted_string.
10402 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10403 where int is good enough, as vsprintf returns an int.
10404 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10406 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10408 Use make_formatted_string to avoid double length calculation.
10409 * lisp.h (make_formatted_string): New prototype.
10410 * alloc.c (make_formatted_string): New function.
10411 * buffer.c (Fgenerate_new_buffer_name): Use it.

10431 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10433 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10435 Move marker debugging code under MARKER_DEBUG.
10436 * marker.c (MARKER_DEBUG): Move marker debugging code under
10437 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10438 for bootstrap with --enable-checking (~3x slowdown reported
10439 by Juanma Barranquero <lekktu@gmail.com>).
10440 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10442 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10444 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10445 See <http://bugs.gnu.org/11825#29>.
10447 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10449 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10450 has no font, use the frame's font. (Bug#11813)
10451 (display_line): Add commentary about displaying truncation glyphs
10453 (produce_special_glyphs): Move here from term.c.
10455 * term.c (produce_special_glyphs): Move to xdisp.c.
10457 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10460 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10462 * xdisp.c (display_line): Avoid warning about implicit declaration
10465 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10467 * lisp.h: Remove empty conditional.
10469 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10471 * lread.c (load_path_check): Now static.
10473 Fix some minor --with-ns problems found by static checking.
10474 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10475 (x_set_font) [!HAVE_X_WINDOWS]:
10476 * image.c (xpm_load_image) [HAVE_NS]:
10477 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10478 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10479 Remove unused local.
10480 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10481 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10482 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10483 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10484 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10485 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10486 Fix pointer signedness problem.
10487 * xfaces.c (FRAME_X_FONT_TABLE):
10488 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10490 2012-07-07 Glenn Morris <rgm@gnu.org>
10492 * lread.c (load_path_check): New function, split from init_lread.
10493 (init_lread): Reorganize. Motivation:
10494 If EMACSLOADPATH is set, check/warn about that rather than the
10495 defaults, which we are not going to use. Hence we can remove
10496 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10497 Don't warn if site-lisp directories are missing.
10498 If not installed, start from a blank load-path, since
10499 PATH_LOADSEARCH refers to the eventual installation directories.
10501 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10503 Support truncation and continuation glyphs on GUI frames, when
10504 fringes are disabled. (Bug#11832)
10505 * xdisp.c (init_iterator): Get dimensions of truncation and
10506 continuation glyphs even if on GUI frames.
10507 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10508 or both, are absent.
10509 (start_display, move_it_in_display_line_to): Handle the case of a
10510 GUI frame without a fringe to display continuation or truncation
10512 (insert_left_trunc_glyphs): Support GUI frames: make sure
10513 truncation glyphs overwrite enough glyphs from the current line to
10514 have sufficient space in pixels.
10515 (display_line): Support truncation and continuation glyphs on GUI
10516 frames. If some spare pixels are left on the line after inserting
10517 the truncation glyphs, fill that space with a stretch glyph of a
10518 suitably computed width.
10520 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10521 produce_glyphs, to support GUI sessions.
10523 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10525 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10527 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10529 Do not require float-time's arg to fit in time_t (Bug#11825).
10530 This works better on hosts where time_t is unsigned, and where
10531 float-time is applied to the (negative) difference between two times.
10532 * editfns.c (decode_time_components): Last arg is now double *,
10533 not int *, and means to store all the result as a double, without
10534 worrying about whether the seconds part fits in time_t.
10535 All callers changed.
10536 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10537 All callers changed.
10538 (Ffloat_time): Do not fail merely because the specified time falls
10539 outside of time_t range.
10541 2012-07-07 Glenn Morris <rgm@gnu.org>
10543 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10544 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10545 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10547 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10549 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10550 Update dependencies.

10558 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10559 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10560 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10561 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10563 * xfont.c (compare_font_names): Redo to omit the need for casts.
10565 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10567 * xfns.c (Fx_change_window_property): Doc fix.
10568 * w32fns.c (Fx_change_window_property): Doc fix.
10570 * w32fns.c (Fx_window_property): Accept the same arguments as the
10571 X Windows version. Doc fix.
10572 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10574 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10575 Eli Zaretskii <eliz@gnu.org>
10577 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10578 Windows-specific code from nt/config.nt moved here.
10579 Obsolete settings removed.
10581 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10583 * process.c: Avoid unnecessary calls to gettime.
10584 (wait_reading_process_output): Don't get the time of day
10585 when gobbling data immediately and not waiting, as there's no need
10586 for it in that case. This removes a FIXME.
10588 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10590 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10591 is defined (Bug#11768).
10593 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10595 Fix marker debugging code.

10597 if buffer is not multibyte.
10598 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10599 Call byte_char_debug_check with correct arguments.
10601 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10603 Compile marker debugging code only if ENABLE_CHECKING is defined.
10604 * marker.c (byte_char_debug_check, count_markers):
10605 Use only if ENABLE_CHECKING is defined.
10606 (byte_debug_flag): Remove.
10607 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10608 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10610 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10612 Avoid code repetition in marker-related functions.

10617 Consistently rename charno to charpos.
10618 (marker_position): Add eassert.

10635 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10636 (save_restriction_save): Use build_marker.
10637 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10638 * window.c (save_window_save): Likewise.
10640 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10642 Do not use Fdelete_overlay in delete_all_overlays

10645 (delete_all_overlays, Fdelete_overlay): Use it.
10646 * minibuf.c (get_minibuffer): Fix comment.
10648 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10650 Port to OpenBSD 5.1 amd64.
10651 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10652 This is needed for OpenBSD, and should be harmless on all BSD systems.
10653 Also, include <sys/sysctl.h>, as it should be available on all
10654 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10655 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10656 use p_pid member, not kp_proc.pid.
10658 2012-07-06 Glenn Morris <rgm@gnu.org>
10660 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.

10673 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10675 Omit needless casts involving void * pointers and allocation.
10676 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10677 as the former is more robust if P's type is changed.
10678 Prefer xzalloc to xmalloc + memset 0.
10679 Simplify malloc-or-realloc to realloc.
10680 Don't worry about xmalloc returning a null pointer.
10681 Prefer xstrdup to xmalloc + strcpy.
10682 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10684 * keyboard.c (apply_modifiers_uncached): Prefer local array to

10690 hscroll is larger than the line width. Fixes long and futile
10691 looping inside extend_face_to_end_of_line (on a TTY) producing
10692 glyphs that are not needed and thrown away.
10694 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

10710 followed by gtk_box_set_homogeneous (Bug#11768).
10711 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10712 (update_theme_scrollbar_width, xg_create_scroll_bar):
10713 Use gtk_scrollbar_new (Bug#11768).

10715 (is_box_type): New function (Bug#11768).
10716 (xg_tool_item_stale_p): Call is_box_type.
10717 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10718 with default display (Bug#11768).
10720 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10722 * xdisp.c (window_hscroll_limited): New function.
10723 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10724 coordinates when window's hscroll is set to insanely large
10725 values. (Bug#11857)
10727 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10799 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10801 * fileio.c (time_error_value): Rename from special_mtime.
10802 The old name's problems were noted by Eli Zaretskii in
10803 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10805 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10806 This variable's comment says Emacs needs at least one GDB-visible
10807 symbol of type enum pvec_type, to work around GDB problems.
10808 The symbol's value doesn't matter.
10810 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10811 that causes compilation to fail on pre-C99 compilers.
10813 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10815 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10816 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10818 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10820 * buffer.c (init_buffer_once): Fix initialization of
10821 headers for buffer_defaults and buffer_local_symbols.
10822 Reported by Juanma Barranquero <lekktu@gmail.com>.
10824 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10826 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10827 * lisp.h (enum pvec_type): Use fewer bits.
10828 (PSEUDOVECTOR_SIZE_BITS): New constant.
10829 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10830 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10831 change in pvec_type.
10832 (PSEUDOVECTOR_TYPEP): New macro.
10833 (TYPED_PSEUDOVECTORP): Use it.
10834 * fns.c (internal_equal): Adapt code to extract pvectype.
10835 * emacs.c (gdb_pvec_type): Update type.
10836 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10837 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10838 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10839 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10840 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10841 abusing vector->header.next.nbytes.
10842 (live_vector_p): Use PVEC_TYPE.
10843 (mark_object): Adapt code to extract pvectype. Use switch.
10845 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10847 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10848 Tighten new eassert a bit.
10850 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10852 Fix compilation with --enable-gcc-warnings and -O1
10853 optimization level.
10854 * doprnt.c (doprnt): Change type of tem to int, initialize
10855 to avoid compiler warning. Add eassert.
10856 * search.c (simple_search): Initialize match_byte to avoid
10857 compiler warning. Add eassert.
10859 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10861 Avoid weird behavior with large horizontal scrolls.
10862 Without this change, for example, large hscroll values would
10863 mess up Emacs's display on Fedora 15 x86, presumably due to
10864 overflows in int calculations in the display code.
10865 Also, if buffers had long lines, Emacs would freeze.
10866 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10867 (set_window_hscroll): New function, containing the old guts of
10868 Fset_window_hscroll. Return the clipped value.
10869 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10870 This avoids the need to check against PTRDIFF_MAX.
10872 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10874 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10876 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10878 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10880 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10881 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10882 since GCC 4.4.6 issues a bogus warning for them.
10884 Fix bugs in file timestamp newness comparisons.
10885 * fileio.c (Ffile_newer_than_file_p):
10886 * lread.c (Fload): Use full timestamp resolution of files,
10887 not just the 1-second resolution, so that files that are only
10888 slightly newer still count as newer.
10889 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10890 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10892 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10894 * fileio.c: Improve handling of file time marker. (Bug#11852)
10895 (special_mtime): New function.
10896 (Finsert_file_contents, Fverify_visited_file_modtime):
10897 Use it to set special mtime values consistently.
10899 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10901 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10902 marker for non-existing file. (Bug#11852)
10904 2012-07-03 Glenn Morris <rgm@gnu.org>
10906 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10907 and did not make it into globals.h).
10909 2012-07-03 Tom Tromey <tromey@redhat.com>
10911 * window.c (Fset_window_margins, Fset_window_fringes)
10912 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10913 * textprop.c (Fprevious_property_change): No longer static.
10914 * syntax.c (Fsyntax_table_p): No longer static.
10915 * process.c (Fget_process, Fprocess_datagram_address): No longer
10917 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
10918 * keyboard.c (Fcommand_execute): No longer static.
10920 * insdel.c (Fcombine_after_change_execute): No longer static.

10935 * dispextern.h: Remove EXFUNs.
10936 * intervals.h: Remove EXFUNs.
10937 * fontset.h: Remove EXFUN.
10938 * font.h: Remove EXFUNs.
10939 * dosfns.c (system_process_attributes): Remove EXFUN.
10940 * keymap.h: Remove EXFUNs.
10941 * lisp.h: Remove EXFUNs.
10942 * w32term.h: Remove EXFUNs.
10943 * window.h: Remove EXFUNs.
10944 * xsettings.h: Remove EXFUN.
10945 * xterm.h: Remove EXFUN.
10947 2012-07-03 Glenn Morris <rgm@gnu.org>
10949 * lisp.h (Frandom): Make it visible to C.
10950 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10951 buffer for invisible buffers. (Bug#1229)
10953 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10955 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10956 values which aren't power of 2.
10957 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10958 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10961 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10963 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10965 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10967 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10969 * alloc.c (allocate_vector_block): Remove redundant
10970 calls to mallopt if DOUG_LEA_MALLOC is defined.
10971 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10972 avoid calls to mallopt if zero_vector is returned.
10974 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10976 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10977 is enabled, avoid dereferencing NULL current_sblock if
10980 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10982 Cleanup basic buffer management.
10983 * buffer.h (struct buffer): Change layout to use generic vector
10984 marking code. Fix some comments. Change type of 'clip_changed'
10985 to bitfield. Remove unused #ifndef old.
10986 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10987 (GET_OVERLAYS_AT): Fix indentation.
10988 (for_each_per_buffer_object_at): New macro.
10989 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10990 (Fbuffer_local_variables): Use it.
10991 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
10992 * alloc.c (allocate_buffer): Adjust to match new layout of
10993 struct buffer. Fix comment.
10994 (mark_overlay): New function.
10995 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10996 Lisp area of struct buffer.
10997 (mark_object): Use it. Adjust marking of misc objects
10998 and related comments.
11000 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11002 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11003 wrapper that is not needed because the wrapped code is a no-op (zero
11004 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11005 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11007 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11009 * alloc.c (mark_buffer): Simplify. Remove prototype.
11010 (mark_object): Add comment. Reorganize marking of vector-like
11011 objects. Use CHECK_LIVE for all vector-like objects except buffers
11012 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11013 Avoid redundant calls to mark_vectorlike for bool vectors.
11015 2012-06-30 Glenn Morris <rgm@gnu.org>
11017 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11019 * epaths.in (PATH_SITELOADSEARCH): New.
11020 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11021 This is rather than relying on --enable-locallisppath elements
11022 having "site-lisp" in their names. (Bug#10208#25, 11658)
11024 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11026 * w32proc.c (sys_select): Accept and ignore one more argument.
11028 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11030 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11031 (pselect) [!MS_DOS]: Redirect to sys_select.
11033 * sysdep.c: Don't include dos.h and dosfns.h.
11035 * process.c (sys_select):
11036 * msdos.c (sys_select): Accept one more argument and ignore it.
11038 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11039 adapt data types and code to that.
11042 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11043 which clashes with the gnulib function of the same name.
11045 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11047 * font.c (font_style_to_value, font_style_symbolic)
11048 (font_prop_validate_style): Add type checks for values in
11051 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11053 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11056 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11058 * xdisp.c (try_window_id): Undo last change.
11060 * w32.c (getwd): Adjust commentary about startup_dir.
11061 (init_environment): Always call sys_access, even in non-MSVC
11062 builds. Don't chdir to the directory of the Emacs executable.
11063 This undoes code from 1997 which was justified by the need to
11064 "avoid conflicts when removing and renaming directories". But its
11065 downside was that every relative file name was being interpreted
11066 relative to the directory of the Emacs executable, which can never
11067 be TRT. In particular, it broke sys_access when called with
11068 relative file names.
11069 (sys_access): Map GetLastError to errno.
11071 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11073 * window.h (struct window): Change type of 'fringes_outside_margins'
11074 to bitfield. Fix comment. Adjust users accordingly.
11075 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
11077 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11080 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11082 * gnutls.c (emacs_gnutls_handshake):
11083 Add QUIT to make the loop interruptible.
11085 2012-06-29 Glenn Morris <rgm@gnu.org>
11087 * charset.c (init_charset): Make lack of etc/charsets fatal.
11089 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11091 * editfns.c (region_limit): Fix type mismatch.
11093 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11095 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11096 undefined. Convert from xassert to eassert.
11097 * nsmenu.m: Convert from xassert to eassert.
11098 * nsterm.m: Likewise.
11100 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
11102 * editfns.c (region_limit): Clip to narrowing (bug#11770).
11104 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11106 Avoid integer overflow on scroll-left and scroll-right.
11107 * window.c (HSCROLL_MAX): New macro.
11108 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11109 overflow when requested scroll falls outside ptrdiff_t range.
11111 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11113 * window.h (struct window): Change type of 'hscroll',
11114 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11115 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11116 Adjust users accordingly.
11117 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11118 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11119 from EMACS_INT to ptrdiff_t.
11120 (make_window): Omit redundant initialization.
11122 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
11124 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
11126 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

11137 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
11138 enabled with --enable-checking=[all,glyphs] configure option.
11139 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11140 adjust comments accordingly.

11142 undefined, adjust comments accordingly.

11189 * alloc.c (allocate_string_data): Remove dead code.
11190 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
11191 avoid GCC warning about unused macro.
11193 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
11195 * alloc.c (allocate_string): Omit intervals initialization.
11196 * alloc.c (make_uninit_multibyte_string): Initialize intervals

11221 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
11222 when building with Clang.

11228 2012-06-26 Eli Zaretskii <eliz@gnu.org>
11230 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
11231 _stricmp and _strnicmp.

11253 * alloc.c: Remove build_string.

11256 function is called with compile-time constant argument.
11257 * image.c (imagemagick_error): Convert to build_string.

11261 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11263 Use sprintf return value instead of invoking strlen on result.
11264 In the old days this wasn't portable, since some sprintf
11265 implementations returned char *. But they died out years ago and
11266 Emacs already assumes sprintf returns int.
11267 Similarly for float_to_string.
11268 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

11275 * xfns.c (syms_of_xfns):
11276 Use sprintf or float_to_string result to avoid need to call strlen.
11277 * data.c (Fnumber_to_string):
11278 Use make_unibyte_string, since the string must be ASCII.
11279 * lisp.h, print.c (float_to_string): Now returns int length.
11280 * term.c (produce_glyphless_glyph):
11281 Use sprintf result rather than recomputing it.

11321 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11322 instead of truncating it to 63 (admittedly a generous limit).

11381 * dispnew.c (Fsleep_for, sit_for):
11382 * keyboard.c (kbd_buffer_get_event):
11383 * process.c (Faccept_process_output):
11384 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11385 This improves on the previous patch, which introduced a bug
11386 when time_t is unsigned and as wide as intmax_t.
11387 See <http://bugs.gnu.org/9000#51>.

11418 language ID in the event parameters.
11420 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11421 event.code, not the obscure "character set ID".
11423 2012-06-23 Chong Yidong <cyd@gnu.org>

11452 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
11454 Support higher-resolution time stamps (Bug#9000).
11455 The time stamps are only nanosecond-resolution at the C level,
11456 since that's the best that any real-world system supports now.
11457 But they are picosecond-resolution at the Lisp level, as that's
11458 easy, and leaves room for future OS improvements.
11460 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11463 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11464 Don't get current time unless it's needed.
11466 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11467 now provides it if it's absent.
11468 (start_atimer): Port to higher-res time stamps.
11469 Check for time stamp overflow. Don't get current time more
11470 often than is needed.
11472 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11473 Include systime.h, not time.h.
11474 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11476 * dired.c: Include stat-time.h.
11477 (Ffile-attributes): File times now have higher resolution.
11479 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11480 (struct image): Timestamp now has higher resolution.
11482 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11483 has at least microseconds now. All uses removed.
11484 (update_frame, update_single_window, update_window, update_frame_1)
11485 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11486 (duration_to_sec_usec): Remove; no longer needed.
11488 * editfns.c (time_overflow): Now extern.
11489 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
11490 (float-time, Fformat_time_string, Fcurrent_time_string)

11494 (decode_time_components, lisp_seconds_argument): New functions.
11495 (make_time): Now static.
11496 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11497 Report an error if the time is invalid, rather than having the caller
11500 * fileio.c: Include <stat-time.h>
11501 (Fcopy_file): Copy higher-resolution time stamps.
11502 Prefer to set the time stamp via a file descriptor if that works.
11503 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11504 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11505 (Fvisited_file_modtime, Fset_visited_file_modtime):
11506 Support higher-resolution time stamps.
11508 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11510 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11512 * image.c (prepare_image_for_display, clear_image_cache)
11513 (lookup_image): Port to higer-resolution time stamps.
11515 * keyboard.c (start_polling, bind_polling_period):
11516 Check for time stamp overflow.
11517 (read_char, kbd_buffer_get_event, timer_start_idle)
11518 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11519 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11520 Port to higher-resolution time stamps. Do not assume time_t is signed.
11521 (decode_timer): New function. Timers are now vectors of length 9,
11522 not 8, to accommodate the picosecond component.
11523 (timer_check_2): Use it.
11525 * nsterm.m (select_timeout, timeval_subtract): Remove.
11526 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11527 as they're a bit more accurate and handle overflow better.
11528 (ns_select): Change prototype to be compatible with pselect.
11529 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11530 * nsterm.h (ns_select): Adjust prototype.
11532 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11533 us-resolution time stamps.
11534 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11536 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11538 * lisp.h (time_overflow): New decl.
11539 (wait_reading_process_output): First arg is now intmax_t, not int,
11540 to accommodate larger waits.
11542 * process.h (struct Lisp_Process.read_output_delay):
11543 Now counts nanoseconds, not microseconds.
11544 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11546 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11547 (wait_reading_process_output):
11548 Port to ns-resolution time stamps.
11549 (Faccept_process_output, wait_reading_process_output):
11550 Check for time stamp overflow. Do not assume time_t is signed.
11551 (select_wrapper): Remove; we now use pselect.
11552 (Fprocess_attributes): Now generates ns-resolution time stamps.
11554 * sysdep.c: Include utimens.h. Don't include utime.h
11555 or worry about struct utimbuf; gnulib does that for us now.
11556 (gettimeofday): Remove; gnulib provides a substitute.
11557 (make_timeval): New function.
11558 (set_file_times): Now sets ns-resolution time stamps.
11559 New arg FD; all uses changed.
11560 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11561 (system_process_attributes):
11562 Now returns ns-resolution time stamp. All uses changed.
11563 Check for time stamp overflow.
11565 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11566 provides a substitute now.
11568 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11569 since it guarantees struct timespec.
11570 (EMACS_TIME): Now struct timespec, so that we can support
11571 ns-resolution time stamps.
11572 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11573 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11574 (EMACS_USECS): Remove.
11575 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11576 so multiply the arg by 1000 before storing it.
11577 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11579 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11580 Port to ns-resolution time stamps.
11581 (EMACS_TIME_NEG_P): Remove; replaced by....
11582 (EMACS_TIME_SIGN): New macro.
11583 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
11584 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
11585 (set_file_times, make_time, lisp_time_argument): Adjust signature.
11586 (make_timeval, make_lisp_time, decode_time_components): New decls.
11587 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11588 that it mishandled time_t overflow. You can't compare by subtracting!
11589 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11590 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11592 * term.c: Include <sys/time.h>.
11593 (timeval_to_Time): New function, for proper overflow wraparound.
11594 (term_mouse_position, term_mouse_click): Use it.
11596 * undo.c (record_first_change): Support higher-resolution time stamps
11597 in the undo buffer.
11598 (Fprimitive_undo): Use them when restoring time stamps.
11600 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11601 (w32_get_internal_run_time):
11602 Port to higher-resolution Emacs time stamps.
11603 (ltime): Now accepts single 64-bit integer, as that's more convenient
11606 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11608 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11609 for compatibility with pselect. Support ns-resolution time stamps.
11611 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11613 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11614 Check for time stamp overflow, and support ns-resolution time stamps.
11616 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11617 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11618 (timeval_subtract): Remove; no longer needed.
11619 (XTflash, XTring_bell, x_wait_for_event):
11620 Port to ns-resolution time stamps. Don't assume time_t is signed.
11622 2012-06-22 Chong Yidong <cyd@gnu.org>

11626 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11628 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11629 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11630 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11631 staticidx goes up to 1597 out of 1600 = 0x640.)
11633 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11635 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
11636 Otherwise, the umask might be mistakenly 0 while handling input signals.
11638 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
11640 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

11646 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
11647 access to `contents' member of Lisp_Vector objects with AREF and ASET
11650 2012-06-19 Chong Yidong <cyd@gnu.org>
11652 * frame.c (delete_frame): When selecting a frame on a different
11653 text terminal, do not alter the terminal's top-frame.
11655 * xdisp.c (format_mode_line_unwind_data): Record the target
11656 frame's selected window and its terminal's top-frame.
11657 (unwind_format_mode_line): Restore them.
11658 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11660 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11661 since tty frames can be explicitly named.
11662 (prepare_menu_bars): Likewise.
11664 * term.c (Ftty_top_frame): New function.
11666 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11668 Port byte-code-meter to modern targets.
11669 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11670 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11671 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11672 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
11673 (METER_1, METER_2): Simplify.
11675 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
11677 * data.c (Fdefalias): Return `symbol' (bug#11686).
11679 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11681 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11682 gets killed during executing of this function (Bug#11665).
11683 Try to always return Qt when the buffer has been actually killed.
11684 (Vkill_buffer_query_functions): In doc-string say that functions
11685 run by this hook should not change the current buffer.
11687 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11689 Fix recently-introduced process.c problems found by static checking.
11690 * process.c (write_queue_push, write_queue_pop, send_process):
11691 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
11692 (write_queue_pop): Fix pointer signedness problem.
11693 (send_process): Remove unused local.
11695 2012-06-17 Chong Yidong <cyd@gnu.org>
11697 * xdisp.c (redisplay_internal): No need to redisplay terminal
11698 frames that are not on top.
11700 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
11702 * process.c (make_process): Initialize write_queue.

11707 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
11709 * lisp.h (eassert): Assume C89 or later.
11710 This removes the need for CHECK.
11711 (CHECK): Remove. Its comments about always evaluating its
11712 argument were confusing, as 'eassert' typically does not evaluate

12108 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12109 Convert pctcpu and pctmem to Lisp float properly.

12137 Use 'float' consistently, rather than 'float' in most places
12138 and 'double' in a couple of places.
12140 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12142 * xdisp.c (handle_stop): Detect whether we have overlay strings
12143 loaded by testing it->current.overlay_string_index to be

12168 decrement the inhibition flag, instead of just setting or
12171 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12173 Remove obsolete '#define static' cruft.
12174 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12175 This #undef was "temporary" in 2000; it is no longer needed
12176 now that '#define static' has gone away.
12177 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12178 (gray_bitmap_bits): Remove; no longer needed.
12179 All uses replaced with definiens.
12180 * xterm.c: Include "bitmaps/gray.xbm".
12182 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
12184 Clean up __executable_start, monstartup when --enable-profiling.
12185 The following changes affect the code only when profiling.
12186 * dispnew.c (__executable_start): Rename from safe_bcopy.
12187 Define only on platforms that need it.
12188 * emacs.c: Include <sys/gmon.h> when profiling.
12189 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
12190 (__executable_start): Remove decl, since lisp.h does it now.
12191 (safe_bcopy): Remove decl; no longer has that name.
12192 (main): Coalesce #if into single bit of code, for simplicity.
12193 Cast pointers to uintptr_t, since standard libraries want integers
12195 * lisp.h (__executable_start): New decl.
12197 2012-05-31 Glenn Morris <rgm@gnu.org>
12199 * image.c (Fimagemagick_types): Doc fix.
12201 2012-05-30 Jim Meyering <meyering@redhat.com>
12203 * callproc.c (Fcall_process_region): Include directory component
12204 in mkstemp error message (Bug#11586).
12206 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
12208 * alloc.c, lisp.h (make_pure_vector): Now static.
12210 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
12212 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
12213 Move to byte-run.el.

12216 (Qdefun): Move from eval.c.
12217 * lisp.h (Qdefun): Remove.
12218 * lread.c (read1): Tiny simplification.
12220 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
12222 Do not create empty overlays with the evaporate property (Bug#9642).
12223 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12224 Bug#9642, but explicitly check that the buffer the overlay would
12225 be moved to is live and rearrange lines to make sure that errors
12226 will not put the overlay in an inconsistent state.
12227 (Fdelete_overlay): Cosmetics.
12229 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12231 * w32term.c (my_bring_window_to_top): New function.
12232 (x_raise_frame): Use handle returned by DeferWindowPos, which
12233 could be different from the original one.
12234 Call my_bring_window_to_top instead of my_set_foreground_window.

12243 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12245 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12246 This avoids undefined behavior that might cause the eassert
12247 to not catch an out-of-range value.
12249 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12251 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
12252 Update dependencies.
12254 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12256 * bidi.c (bidi_mirror_char): Fix last change.
12258 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

12261 when referring to sectname field in printf format.
12263 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
12265 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12266 Only r_alloc_inhibit_buffer_relocation needed to be added;
12267 the others were already declared.
12269 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12270 before checking whether it's out of range. Put the check inside
12272 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12274 2012-05-27 Ken Brown <kbrown@cornell.edu>
12276 * callproc.c (Fcall_process): Restore a line that was accidentally
12277 commented out in the 2011-02-13 change (bug#11547).
12279 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12281 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12282 defined on ralloc.c.
12284 * buffer.c [REL_ALLOC]: Remove prototypes of
12285 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12286 they are now on lisp.h.
12288 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12290 * search.c (search_buffer): Use it to inhibit relocation of buffer
12291 text while re_search_2 is doing its job, because re_search_2 is
12292 passed C pointers to buffer text. (Bug#11519)
12294 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12295 Update value to 24.
12297 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12298 state after an additional call to move_it_in_display_line_to, keep
12299 the values of it->max_ascent and it->max_descent found for the
12301 (pos_visible_p): Revert the comparison against bottom_y to what it
12302 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12305 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12307 Fix coding-related core dumps with gcc -ftrapv.
12308 The code was computing A - B, where A and B are pointers, and B is
12309 random garbage. This can lead to core dumps on platforms that
12310 have special pointer registers, and it also leads to core dumps on
12311 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12312 A - B only when B is initialized properly.
12313 * coding.c (coding_set_source, coding_set_destination): Return void.
12314 (coding_change_source, coding_change_destinations): New functions,
12315 with the old behaviors of coding_set_source and coding_set_destination.
12316 All callers that need an offset changed to use these new functions.
12318 2012-05-26 Glenn Morris <rgm@gnu.org>
12320 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
12322 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12324 Extend mouse support on W32 text-mode console.
12325 * xdisp.c (draw_row_with_mouse_face):
12326 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12328 * w32console.c: Include window.h.
12329 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12331 (initialize_w32_display): Initialize mouse-highlight data.
12333 * w32inevt.c: Include termchar.h and window.h.
12334 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12335 moves, call note_mouse_highlight. If help_echo changed, call
12336 gen_help_event to produce help-echo message in the echo area.
12337 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12340 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12342 * lread.c (read1): Simplify slightly to avoid an overflow warning
12343 with GCC 4.7.0 on x86-64.
12345 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12347 * bidi.c (bidi_mirror_char): Revert last change: an int is
12348 definitely wide enough here.
12350 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12352 Fix integer width and related bugs (Bug#9874).
12353 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
12354 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
12355 (string_bytes, check_sblock, allocate_string_data):
12356 (compact_small_strings, Fmake_bool_vector, make_string)
12357 (make_unibyte_string, make_multibyte_string)
12358 (make_string_from_bytes, make_specified_string)
12359 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
12360 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
12362 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12363 (allocate_pseudovector):
12364 Use int, not EMACS_INT, where int is wide enough.
12365 (inhibit_garbage_collection, Fgarbage_collect):
12366 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12367 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12368 int might not be wide enough.
12369 (bidi_cache_search, bidi_cache_find, bidi_init_it)
12370 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
12371 (bidi_at_paragraph_end, bidi_find_paragraph_start)
12372 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
12373 (bidi_level_of_next_char, bidi_move_to_visually_next):
12374 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12375 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
12376 (Fkill_buffer, Fset_buffer_major_mode)
12377 (advance_to_char_boundary, Fbuffer_swap_text)
12378 (Fset_buffer_multibyte, overlays_at, overlays_in)
12379 (overlay_touches_p, struct sortvec, record_overlay_string)
12380 (overlay_strings, recenter_overlay_lists)
12381 (adjust_overlays_for_insert, adjust_overlays_for_delete)
12382 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
12383 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
12384 (Foverlay_recenter, last_overlay_modification_hooks_used)
12385 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
12386 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12387 (validate_region): Omit unnecessary test for b <= e,
12388 since that's guaranteed by the previous test.
12389 (adjust_overlays_for_delete): Avoid pos + length overflow.
12390 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12391 (report_overlay_modification):
12392 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12393 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12394 Omit pointer cast, which isn't needed anyway, and doesn't work
12395 after the EMACS_INT -> ptrdiff_t change.
12396 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12397 * buffer.h: Adjust decls to match defn changes elsewhere.
12398 (struct buffer_text, struct buffer):
12399 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12400 Use EMACS_INT, not int, where int might not be wide enough.
12401 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12402 not int, to avoid needless 32-bit limit on 64-bit hosts.
12403 (exec_byte_code): Use tighter memory-full test, one that checks
12404 for alloca overflow. Don't compute the address of the object just
12405 before an array, as that's not portable. Use EMACS_INT, not
12406 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12407 * callint.c (Fcall_interactively):
12408 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12409 * callproc.c (call_process_kill, Fcall_process):
12410 Don't assume pid_t fits into an Emacs fixnum.
12411 (call_process_cleanup, Fcall_process, child_setup):

12415 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12416 (Fcall_process): Simplify handling of volatile integers.

12419 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
12420 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12421 (casify_object): Avoid integer overflow when overallocating buffer.
12422 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12423 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12424 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12425 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12426 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
12427 integers are now checked earlier. All uses replaced with XINT.
12429 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12430 For CCL_MapSingle, check that content and value are in int range.
12431 (ccl_driver, Fregister_code_conversion_map):
12432 Check that Vcode_version_map_vector is a vector.
12433 (resolve_symbol_ccl_program): Check that vector header is in range.
12434 Always copy the vector, so that we can check its contents reliably
12435 now rather than having to recheck each instruction as it's being
12436 executed. Check that vector words fit in 'int'.
12437 (ccl_get_compiled_code, Fregister_ccl_program)
12438 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12439 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12440 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12441 contents are in range.
12442 (Fccl_execute_on_string): Check that status is in range.
12443 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12444 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12445 Accept and return EMACS_INT, not int, because callers can pass values
12446 out of 'int' range.
12447 (c_string_width, strwidth, lisp_string_width, chars_in_text)
12448 (multibyte_chars_in_text, parse_str_as_multibyte)

12451 (string_escape_byte8, Fget_byte):
12452 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12453 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12454 avoid mishandling large integers.
12455 * character.h: Adjust decls to match defn changes elsewhere.
12456 * charset.c (load_charset_map_from_file, find_charsets_in_text)
12457 (Ffind_charset_region):
12458 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

12461 Don't assume fixnum fits in int.
12462 (load_charset_map_from_vector, Fmap_charset_chars):
12463 Remove now-unnecessary CHECK_NATNUMs.
12464 (Fdefine_charset_internal): Check ranges here, more carefully.
12465 Don't rely on undefined behavior with signed left shift overflow.
12466 Don't assume unsigned int fits into fixnum, or that fixnum fits
12467 into unsigned int. Don't require max_code to be a valid fixnum;
12468 that's not true for gb10830 4-byte on a 32-bit host. Allow
12469 invalid_code to be a cons, for the same reason. Require code_offset
12470 to be a character. Avoid int overflow if max_char is close
12472 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12473 this is intended anyway and avoids some undefined behavior.
12474 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12475 INDEX_TO_CODE_POINT, as that's what it expects.
12476 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12477 * charset.h (DECODE_CHAR): Return int, not unsigned;
12478 this is what was intended anyway, and it avoids undefined behavior.
12479 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12480 integer-overflow issues.
12481 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12482 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12483 where the argument is EMACS_INT, and this behavior is not intended.
12484 * chartab.c (Fmake_char_table, Fset_char_table_range)
12485 (uniprop_get_decoder, uniprop_get_encoder):
12486 Don't assume fixnum fits in int.
12487 * cmds.c (move_point): New function, that does the gist of
12488 Fforward_char and Fbackward_char, but does so while checking
12489 for integer overflow more accurately.
12490 (Fforward_char, Fbackward_char): Use it.
12491 (Fforward_line, Fend_of_line, internal_self_insert)
12492 (internal_self_insert):
12493 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12494 Fix a FIXME, by checking for integer overflow when calculating
12495 target_clm and actual_clm.

12527 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12528 (consume_chars): Rewrite to not calculate an address outside buffer.
12529 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
12530 Don't access memory outside of the args array.
12531 (Fdefine_coding_system_internal): Check for charset-id overflow.
12532 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
12533 result of ENCODE_CHAR.
12534 * coding.h: Adjust decls to match defn changes elsewhere.
12535 (struct coding_system):
12536 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12551 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12552 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
12553 Do not attempt to compute the address of the object just before a

13239 and `display_arg' (bug#9754).
13241 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
13243 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
13245 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
13246 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
13248 2012-05-18 Eli Zaretskii <eliz@gnu.org>
13250 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
13252 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
13253 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
13255 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
13256 reference to image_cache->refcount.
13257 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
13259 2012-05-17 Juri Linkov <juri@jurta.org>
13261 * search.c (Fword_search_regexp, Fword_search_backward)
13262 (Fword_search_forward, Fword_search_backward_lax)
13263 (Fword_search_forward_lax): Move functions to isearch.el
13264 (bug#10145, bug#11381).
13266 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13268 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13270 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13272 * lread.c (init_obarray): Declare Qt and Qnil as special.
13274 2012-05-14 Glenn Morris <rgm@gnu.org>
13276 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13277 Put "libexec" before "bin", for the sake of init_callproc_1.
13279 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13281 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13283 * unexaix.c: Port to more-recent AIX compilers.
13284 (report_error, report_error_1, make_hdr, copy_sym)
13285 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13286 Make arguments const char *, not char *, to avoid violations of C
13287 standard and to fix some AIX warnings reported by Gilles Pion.
13289 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13291 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13292 already have overlays loaded.
13293 (handle_single_display_spec): Before returning without displaying
13294 fringe bitmap, synchronize the bidi iterator with the main display
13295 iterator, by calling iterate_out_of_display_property.
13296 (iterate_out_of_display_property): Detect buffer iteration by
13297 testing that it->string is a Lisp string.
13298 (get_next_display_element): When the current object is exhausted,
13299 and there's something on it->stack, call set_iterator_to_next to
13300 proceed with what's on the stack, instead of returning zero.
13301 (set_iterator_to_next): If called at the end of a Lisp string,
13302 proceed to consider_string_end without incrementing string
13303 position. Don't increment display vector index past the end of
13304 the display vector. (Bug#11417)
13305 (pos_visible_p): Don't report a position visible when move_it_to
13306 stopped at the last line of window, which happens to be scanned
13307 backwards by the bidi iteration. (Bug#11464)
13309 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13311 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13312 and right-margin display specs even if the spec is invalid or we
13313 are on a TTY, and thus unable to display on the fringes.
13314 That's because the text with the property will not be displayed anyway,
13315 so we need to signal to the caller that this is a "replacing"
13316 display spec. This fixes display when the spec is invalid or we
13319 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13321 * unexaix.c (make_hdr): Fix typo in prototype.
13322 This bug broke the build on AIX. Problem reported by Gilles Pion.
13324 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13326 * keyboard.c (kbd_buffer_get_event): Read special events also in
13327 batch mode. (Bug#11415)
13329 2012-05-12 Glenn Morris <rgm@gnu.org>
13331 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13333 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13335 * lisp.mk (lisp): Add newcomment.elc.
13337 2012-05-12 Glenn Morris <rgm@gnu.org>
13339 * Makefile.in (MKDIR_P): New, set by configure.
13340 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13342 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13344 Remove unused function hourglass_started.
13345 * dispextern.h (hourglass_started):
13346 * w32fns.c (hourglass_started):
13347 * xdisp.c (hourglass_started): Remove.
13349 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13351 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13352 Update dependencies.
13354 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13356 * xgselect.c (xg_select): Put maxfds+1 into a var.
13357 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13359 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13361 2012-05-10 Dave Abrahams <dave@boostpro.com>
13363 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13364 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13366 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13368 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13369 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13370 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13371 Initialize xd_registered_buses.
13373 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13375 Untag more efficiently if USE_LSB_TAG.
13376 This is based on a proposal by YAMAMOTO Mitsuharu in
13377 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13378 For an admittedly artificial (nth 8000 longlist) benchmark on
13379 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13380 Emacs's overall text size by 1%.
13381 * lisp.h (XUNTAG): New macro.
13382 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13383 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13384 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13385 * eval.c (Fautoload):
13386 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13387 * frame.h (XFRAME): Use XUNTAG.
13389 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13390 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13391 Remove unportable assumptions about print widths of types like
13393 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13394 intptr_t when converting between pointer and integer, to avoid GCC
13395 warnings about wrong width.
13397 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13399 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13400 stack for each reader_thread, instead of defaulting to 8MB
13401 determined by the linker. This avoids failures in creating
13402 subprocesses on Windows 7, see the discussion in this thread:
13403 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13405 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13407 Fix up display of the *Minibuf-0* buffer in the mini window.
13408 * keyboard.c (read_char): Don't clear the echo area if there's no
13410 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13411 contents of *Minibuf-0*) if there's no message displayed in its stead.
13413 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13415 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13418 2012-05-06 Chong Yidong <cyd@gnu.org>
13420 * lisp.mk (lisp): Update.
13422 2012-05-05 Jim Meyering <meyering@redhat.com>
13424 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13426 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13428 * data.c (PUT_ERROR): New macro.
13429 (syms_of_data): Use it. Add new error type `user-error'.
13430 * undo.c (user_error): New function.
13431 (Fprimitive_undo): Use it.
13432 * print.c (print_error_message): Adjust print style for `user-error'.
13433 * keyboard.c (user_error): New function.
13434 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13436 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13438 Do not limit current-time-string to years 1000..9999.
13439 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13440 (Fcurrent_time_string): Support any year that is supported by the
13441 underlying localtime representation. Don't use asctime, as it
13442 has undefined behavior for years outside the range -999..9999.
13444 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13446 Fix race conditions involving setenv, gmtime, localtime, asctime.
13447 Without this fix, interrupts could mess up code that uses these
13448 nonreentrant functions, since setting TZ invalidates existing
13449 tm_zone or tzname values, and since most of these functions return
13450 pointers to static storage.
13451 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13452 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13453 Grow the critical sections to include not just invoking
13454 localtime/gmtime, but also accessing these functions' results
13455 including their tm_zone values if any, and any related TZ setting.
13456 (format_time_string): Last arg is now struct tm *, not struct tm **,
13457 so that the struct tm is saved in the critical section.
13458 All callers changed. Simplify allocation of initial buffer, partly
13459 motivated by the fact that memory allocation needs to be outside
13460 the critical section.
13462 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13464 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13465 with RESET_INTERVAL.
13467 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13468 Remove duplicated buffer name initialization.
13470 2012-05-02 Jim Meyering <jim@meyering.net>
13472 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13474 * xfns.c (x_window): Use xstrdup (Bug#11375).
13476 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13478 * xdisp.c (pos_visible_p): If already at a newline from the
13479 display string before the 'while' loop, don't walk back the glyphs
13480 from it3.glyph_row. Solves assertion violation when the display
13481 string begins with a newline (egg.el). (Bug#11367)
13483 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13485 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13488 2012-05-01 Glenn Morris <rgm@gnu.org>
13490 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13491 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13492 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13493 All were removed before 23.1.
13495 * dispnew.c: Remove HAVE_LIBNCURSES test;
13496 it is always true on relevant platforms.
13498 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13499 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13501 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13503 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13505 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13506 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13509 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13511 Do not avoid creating empty evaporating overlays (Bug#9642).
13512 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13513 That is, do not delete an evaporating overlay if it becomes
13514 empty after its bounds are adjusted to fit within its buffer.
13515 This fix caused other problems, and I'm reverting it until we get
13516 to the bottom of them.
13518 2012-04-27 Chong Yidong <cyd@gnu.org>
13520 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13522 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13524 * xdisp.c (pos_visible_p): If the window start position is beyond
13525 ZV, start the display from buffer beginning. Prevents assertion
13526 violation in init_iterator when the minibuffer window is scrolled
13527 via the scroll bar.
13529 * window.c (window_scroll_pixel_based): Likewise.
13531 2012-04-27 Chong Yidong <cyd@gnu.org>
13533 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13535 2012-04-27 Glenn Morris <rgm@gnu.org>
13537 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13538 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13540 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13542 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13543 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13545 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13547 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13548 display element, check also the underlying string or buffer
13549 character. (Bug#11341)
13551 * w32menu.c: Include w32heap.h.
13552 (add_menu_item): If the call to AppendMenuW (via
13553 unicode_append_menu) fails, disable Unicode menus only if we are
13554 running on Windows 9X/Me.
13556 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13558 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13559 (xgetint): Add missing shift for LSB tags.
13561 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13563 * keyboard.c (read_char): Don't wipe echo area for select window
13564 events: These might get delayed via `mouse-autoselect-window'
13567 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13569 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13570 manipulation of :loaded-from data.
13572 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13574 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13575 now a cons (bug#11311).
13577 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13579 Do not create empty overlays with the evaporate property (Bug#9642).
13580 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13581 if it becomes empty after its bounds are adjusted to fit within
13582 its buffer. Without this fix, in a nonempty buffer (let ((o
13583 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13584 yields an empty overlay that has the evaporate property, which is
13585 not supposed to happen.
13587 Fix minor GTK3 problems found by static checking.
13588 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13589 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13590 (struct _EmacsFixedClass, emacs_fixed_get_type):
13591 Move decls here from emacsgtkfixed.h, since they needn't be public.
13592 (emacs_fixed_get_type): Now static.
13593 (emacs_fixed_class_init): Omit unused local.
13594 (emacs_fixed_child_type): Remove; unused.
13595 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13596 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13597 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13598 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
13599 (EMACS_FIXED_GET_CLASS): Remove; unused.
13600 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
13602 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
13603 Problem reported by Juanma Barranquero for Windows -Wunused-function.
13605 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13607 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13608 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13609 (__malloc_size_t, __malloc_ptrdiff_t):
13610 Remove. All uses removed, replaced by the definiens if needed,
13611 since we can assume C89 or better now.
13612 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

13620 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13621 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13622 Define using prototypes, not old style.
13623 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
13624 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
13625 (align): Don't assume that signed integer overflow wraps around.
13626 Omit unused local var.
13627 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
13628 (_free_internal_nolock, memalign, mallochook, reallochook):
13629 Omit no-longer-needed casts.
13630 (valloc): Use getpagesize, not __getpagesize.
13631 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
13632 (struct hdr): The 'magic' member is now size_t, not unsigned long.
13634 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
13636 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
13638 Move functions from C to Lisp. Make non-blocking method calls
13639 the default. Implement further D-Bus standard interfaces.
13641 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

13657 (xd_signature, xd_append_arg): Allow float for integer types.
13658 (xd_get_connection_references): New function.
13659 (xd_get_connection_address): Rename from xd_initialize.
13660 Return cached address.
13661 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
13662 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp

13666 (Fdbus_get_unique_name): Make stronger parameter check.
13667 (Fdbus_message_internal): New defun.

13669 (Fdbus_method_return_internal, Fdbus_method_error_internal)
13670 (Fdbus_send_signal, Fdbus_register_service)

13698 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
13700 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13702 * sysdep.c [__FreeBSD__]: Minor cleanups.
13703 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13704 Use Emacs indenting style more consistently. Avoid some casts.

13709 * sysdep.c (list_system_processes, system_process_attributes):
13710 Add implementation for FreeBSD (Bug#5243).

13716 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
13718 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
13719 It is never used otherwise.
13721 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13723 * print.c (print_preprocess): Only check print_depth if print-circle
13725 (print_object): Check for cycles even when print-circle is nil and
13726 print-gensym is t, but only check print_depth if print-circle is nil.

13730 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13731 set the status to "failed" and ensure that sentinel is run.
13733 2012-04-20 Glenn Morris <rgm@gnu.org>
13735 * process.c (Fset_process_inherit_coding_system_flag)
13736 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

13746 farther than the first row after the header line, if any.
13747 Don't consider the header-line row as "partially visible", even if
13748 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
13750 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

13764 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
13765 -Wunused-result, -Wunused-variable. This should go away once
13766 the Emacs and Gnulib regex code is merged.
13767 (xmalloc, xrealloc): Now static.
13769 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

13786 New extern decls, to avoid calling undeclared functions.
13787 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13788 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13789 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13790 (NEED_MEM_INSERT): New macro.
13791 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13792 Remove one incorrect comment and fix another.

13807 Remove decls. This fixes an "It stinks!".
13809 * alloc.c (which_symbols): Fix alignment issue / type clash.
13811 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13813 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
13814 (struct Lisp_Misc_Any): Likewise.

13828 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13829 * s/netbsd.h, s/sol2-6.h:
13830 Remove definition of GC_MARK_STACK, since the default now works.
13831 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

13833 no longer the default.
13834 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13836 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13838 * lread.c (lisp_file_lexically_bound_p):

13857 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
13859 2012-04-11 Daniel Colascione <dancol@dancol.org>
13861 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13862 against is gone. It's better to use vfork now so that when Cygwin
13863 gains a new, working vfork, we use it automatically (bug#10398).
13865 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
13867 * window.c (save_window_save): Obey window-point-insertion-type.

13885 * w32.c (w32_delayed_load): Record the full path of the library
13886 being loaded (bug#10424).
13888 2012-04-09 Glenn Morris <rgm@gnu.org>
13890 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13891 not just in the obarray, before snarfing them. (Bug#11036)

13908 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13909 attempts per process (connection).
13911 2012-04-09 Chong Yidong <cyd@gnu.org>
13913 * eval.c (Fuser_variable_p, user_variable_p_eh)

13915 (Fdefvar): Caller changed.
13917 * callint.c (Finteractive, Fcall_interactively):
13918 * minibuf.c (Fread_variable): Callers changed.
13920 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13922 * xdisp.c (set_cursor_from_row): If the display string appears in
13923 the buffer at position that is closer to point than the position
13924 after the display string, display the cursor on the first glyph of
13925 the display string. Fixes cursor display when a 'display' text
13926 property immediately follows invisible text. (Bug#11094)
13928 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13930 composite.c: use 'double' consistently
13931 * composite.c (get_composition_id): Use 'double' consistently
13932 instead of converting 'float' to 'double' and vice versa; this is
13933 easier to understand and avoids a GCC warning.
13935 2012-04-09 Glenn Morris <rgm@gnu.org>
13937 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13938 preparation for dumping it with emacs. (Bug#4789)

13960 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13961 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13962 objects, as mark_maybe_pointer will catch them otherwise.

13980 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13981 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13982 [!WINDOWSNT]: New macros.
13983 (init_libxml2_functions, libxml2_loaded_p): New functions.
13984 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13985 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13986 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13987 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13989 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13990 Call init_libxml2_functions before calling libxml2 functions.
13991 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13993 * emacs.c: Don't include libxml/parser.h.

13999 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14001 * indent.c (Fvertical_motion): If there is a display string at
14002 point, use it.vpos to compute how many lines to backtrack after
14003 move_it_to point. (Bug#11133)
14005 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14007 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14008 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14009 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14010 macros related to unification of CJK characters. For the details,
14011 see the discussion following the message here:
14012 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14014 2012-04-04 Chong Yidong <cyd@gnu.org>
14016 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14018 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14020 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

14028 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14030 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14031 position we get to after a call to move_it_to fails the
14032 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14033 only if we wind up in a string from display property. (Bug#11063)
14035 * window.c (Fdelete_other_windows_internal): Invalidate the row
14036 and column information about mouse highlight, so that redisplay
14037 restores it after reallocating the glyph matrices. (Bug#7464)
14039 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14040 string comes from a `display' text property, use the buffer
14041 position of that property as if we actually saw that position in
14043 (move_it_by_lines): Remove the assertion that
14044 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14045 violated when there's a before-string at the beginning of a line.
14048 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14050 * xdisp.c (append_space_for_newline): If the default face was

14052 (extend_face_to_end_of_line): Use the remapped default face for
14053 extending the face to the end of the line.
14054 (display_line): Call extend_face_to_end_of_line when the default
14055 face was remapped. (Bug#11068)
14057 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14059 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

14077 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14078 (command_loop_1): Use it; inhibit selection update for

14083 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14085 2012-03-25 Kenichi Handa <handa@m17n.org>
14087 * dispextern.h (struct glyph): Change the bit length of
14088 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14090 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14092 * s/ms-w32.h (tzname): Include time.h before redirecting to

14103 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14105 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14106 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14107 when fetching a multibyte character consumes more bytes than
14108 CHAR_BYTES returns, due to unification of CJK characters in
14109 string_char. (Bug#11073)
14111 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14113 * process.c (wait_reading_process_output): Handle pty disconnect
14114 by refraining from sending oneself a SIGCHLD (bug#10933).
14116 2012-03-22 Chong Yidong <cyd@gnu.org>
14118 * dispextern.h (struct it): New member string_from_prefix_prop_p.
14120 * xdisp.c (push_prefix_prop): Rename from push_display_prop.

14137 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
14138 to reflect default non-nil value of redisplay-dont-pause.
14140 2012-03-19 Kenichi Handa <handa@m17n.org>
14142 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
14143 it fit in a valid range (Bug#11003).
14145 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14147 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14148 that is not from display property, accept the row as a "cursor
14149 row" if one of the string's character has a non-nil `cursor'
14150 property. Fixes cursor positioning when there are newlines in
14151 overlay strings, e.g. in icomplete.el. (Bug#11035)
14153 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14155 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

14184 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14187 2012-03-03 Glenn Morris <rgm@gnu.org>
14189 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14191 2012-03-02 Eli Zaretskii <eliz@gnu.org>

14194 position past the first glyph_row that ends at ZV. (Bug#10902)
14195 (redisplay_window, next_element_from_string): Fix typos in
14197 (redisplay_window): Pass to move_it_vertically the margin in
14198 pixels, not in screen lines.
14200 2012-03-02 Glenn Morris <rgm@gnu.org>
14202 * buffer.c (buffer-list-update-hook): Doc fix.
14204 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14206 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14207 push_it before setting up the iterator for the first overlay
14208 string, even if we have an empty string loaded.
14209 (next_overlay_string): If there's an empty string on the iterator
14210 stack, pop the stack. (Bug#10903)
14212 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14214 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14215 Suggested by Stefan Monnier in
14216 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14217 * alloc.c (widen_to_Lisp_Object): New static function.
14218 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14219 and widening them to Lisp_Objects. This would work even if
14220 USE_LSB_TAG is defined and wide integers are used, which might
14221 happen in a future version of Emacs.
14223 2012-02-25 Chong Yidong <cyd@gnu.org>
14225 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
14228 * xselect.c (Fx_selection_exists_p): Doc fix.

14230 before saving to clipboard manager.
14232 2012-02-24 Chong Yidong <cyd@gnu.org>
14234 * keyboard.c (process_special_events): Handle all X selection
14235 requests in kbd_buffer, not just the next one (Bug#8869).
14237 2012-02-23 Chong Yidong <cyd@gnu.org>
14239 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14240 call when setting menu-bar-lines and tool-bar-lines parameters.
14241 (unwind_create_frame_1): New helper function.
14243 * window.c (inhibit_window_configuration_change_hook): New var.
14244 (run_window_configuration_change_hook): Obey it.
14245 (syms_of_window): Initialize it.

14254 * fileio.c (Vfile_name_handler_alist): Doc fix.
14256 * buffer.c (Fget_file_buffer): Protect against invalid file
14257 handler return value.
14259 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
14261 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
14262 when computing $valmask.
14264 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14265 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14266 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14267 It's useless in that case, and it can cause problems on hosts
14268 that allocate halves of EMACS_INT values separately.
14269 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14270 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14271 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14272 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14273 it avoids undefined behavior on hosts where shifting right by more
14274 than the word width has undefined behavior.
14276 2012-02-19 Chong Yidong <cyd@gnu.org>
14278 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14279 (Funhandled_file_name_directory, Ffile_name_as_directory)
14280 (Fdirectory_file_name, Fexpand_file_name)
14281 (Fsubstitute_in_file_name): Protect against invalid file handler
14282 return values (Bug#10845).
14284 2012-02-18 Eli Zaretskii <eliz@gnu.org>
14286 * .gdbinit (pitx): Fix incorrect references to fields of the

14296 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14298 2012-02-15 Chong Yidong <cyd@gnu.org>
14300 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14301 marked as special. Also, starting docstrings with * is obsolete.

14316 2012-02-12 Chong Yidong <cyd@gnu.org>
14318 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14319 as that creates a dangerous corner case.
14321 * window.c (Fdelete_window_internal): Invalidate the mouse
14322 highlight (Bug#9904).
14324 2012-02-12 Glenn Morris <rgm@gnu.org>

14329 * nsselect.m (Fx_own_selection_internal)
14330 (Fx_disown_selection_internal, Fx_selection_exists_p)
14331 (Fx_selection_owner_p, Fx_get_selection_internal):
14332 Sync docs and argument specs with the xselect.c versions.
14334 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

14354 2012-02-07 Chong Yidong <cyd@gnu.org>
14356 * buffer.c (Fbuffer_local_variables)
14357 (buffer_lisp_local_variables): Handle unbound vars correctly;
14358 don't let Qunbound leak into Lisp.
14360 2012-02-07 Glenn Morris <rgm@gnu.org>
14362 * image.c (Fimagemagick_types): Doc fix.
14364 * image.c (imagemagick-render-type): Change it from a lisp object
14365 to an integer. Move the doc here from the lisp manual.

14382 2012-02-04 Eli Zaretskii <eliz@gnu.org>
14384 * w32.c (get_emacs_configuration_options):
14385 Include --enable-checking, if specified, in the return value.
14387 2012-02-04 Martin Rudalics <rudalics@gmx.at>
14389 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
14390 after rounding frame sizes. (Bug#9723)

14395 before BEGV. (Bug#10696)
14397 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
14399 Handle overflow when computing char display width (Bug#9496).
14400 * character.c (char_width): Return EMACS_INT, not int.
14401 (char_width, c_string_width): Check for overflow when
14402 computing the width; this is possible now that individual
14403 characters can have unbounded width. Problem introduced
14404 by merge from Emacs 23 on 2012-01-19.

14428 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
14430 (x_produce_glyphs): If the component of a composition is a null

14435 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
14436 first 2 arguments are identical. This makes inserting large
14437 output from a subprocess an order of magnitude faster on
14438 MS-Windows, where all sbrk'ed memory is always contiguous.
14440 2012-01-31 Glenn Morris <rgm@gnu.org>
14442 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

14523 2012-01-11 Glenn Morris <rgm@gnu.org>
14525 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
14526 from load-path also when installation-directory is nil. (Bug#10208)
14528 2012-01-10 Glenn Morris <rgm@gnu.org>
14530 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.

14533 Update template values to be closer to their typical values these days.
14535 2012-01-09 Eli Zaretskii <eliz@gnu.org>
14537 * xdisp.c (rows_from_pos_range): Accept additional argument
14538 DISP_STRING, and accept any glyph in a row whose object is that
14539 string as eligible for mouse highlight. Fixes mouse highlight of
14540 display strings from overlays. (Bug#10464)
14542 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
14544 emacs: fix an auto-save permissions race condition (Bug#10400)
14545 * fileio.c (auto_saving_dir_umask): New static var.
14546 (Fmake_directory_internal): Use it.
14547 (do_auto_save_make_dir): Set it, instead of invoking chmod after

14549 too-generous permissions to the directory.
14550 (do_auto_save_eh): Clear it.
14551 (Fdo_auto_save): Catch all errors, not just file errors, so
14552 that the var is always cleared.

14609 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
14610 property that ends at ZV, so that the bidi iteration could be

15055 Problem reported by Andreas Schwab in
15056 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
15057 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15058 is set, removing the need for VIRT_ADDRESS_VARIES.
15059 (PURE_P): Use a more-efficient implementation that needs just one
15060 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
15061 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
15062 to 4 (xorl, subq, cmpq, setbe).
15063 * alloc.c (pure): Always extern now, since that's the
15064 VIRT_ADDR_VARIES behavior.
15065 (PURE_POINTER_P): Use a single comparison, not two, for
15066 consistency with the new puresize.h.
15067 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

15074 (erase_phys_cursor, update_window_cursor, show_mouse_face)
15075 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
15076 behave as if the cursor position were at the window margin.
15078 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15079 and the cursor position is out of bounds, behave as if the cursor
15080 position were at the window margin. (Bug#10075)

15542 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
15543 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
15545 (w32font_open_internal, compute_metrics):
15546 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15547 instead of calling the "wide" APIs directly.
15549 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
15551 * w32.h (syms_of_w32font): Add prototype.
15553 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15555 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
15556 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
15557 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
15558 (Fmove_to_window_line): Doc fix.
15560 2011-10-27 Chong Yidong <cyd@gnu.org>
15562 * process.c (make_process): Set gnutls_state to NULL.
15564 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15565 non-NULL, regardless of GNUTLS_INITSTAGE.
15566 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
15567 an error. Set process slots as soon as we allocate them.
15569 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
15571 2011-10-27 Chong Yidong <cyd@gnu.org>
15573 * gnutls.c (emacs_gnutls_deinit): New function.
15574 Deallocate credentials structures as well as calling gnutls_deinit.
15575 (Fgnutls_deinit, Fgnutls_boot): Use it.
15577 * process.c (make_process): Initialize GnuTLS credentials to NULL.
15578 (deactivate_process): Call emacs_gnutls_deinit.
15580 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15582 * image.c (x_create_x_image_and_pixmap):
15583 * w32.c (sys_rename, w32_delayed_load):
15584 * w32font.c (fill_in_logfont):
15585 * w32reg.c (x_get_string_resource): Silence compiler warnings.
15587 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
15589 * w32fns.c (w32_default_color_map): New function,
15590 extracted from Fw32_default_color_map.
15591 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
15593 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
15595 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
15597 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
15599 * keyboard.c (test_undefined): New function (bug#9751).
15600 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
15602 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
15604 * sysdep.c (init_sys_modes): Fix the check for the controlling
15605 terminal (Bug#6649).
15607 2011-10-20 Eli Zaretskii <eliz@gnu.org>
15609 * dispextern.h (struct bidi_it): New member next_en_type.
15611 * bidi.c (bidi_line_init): Initialize the next_en_type member.
15612 (bidi_resolve_explicit_1): When next_en_pos is valid for the
15613 current character, check also for next_en_type being WEAK_EN.
15614 (bidi_resolve_weak): Don't enter the expensive loop if the current
15615 position is before next_en_pos. Record the bidi type of the first
15616 non-ET, non-BN character we find, in addition to its position.
15617 (bidi_level_of_next_char): Invalidate next_en_type when
15618 next_en_pos is over-stepped.
15620 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15622 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15623 * editfns.c: Rewrite current-time-zone so that it invokes
15624 the equivalent of (format-time-string "%Z") to get the time zone name.
15625 This fixes a bug when the time zone name contains characters that
15626 need converting from the system time locale to Emacs internal format.
15627 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15628 that patch fixed format-time-string to do the conversion, but
15629 I forgot to fix current-time-zone.
15630 (format_time_string): New function, containing most of
15631 what Fformat_time_string used to contain.
15632 (Fformat_time_string): Rewrite in terms of format_time_string.
15633 This doesn't change this function's behavior.
15634 (current-time-zone): Rewrite to use format_time_string.
15635 This fixes the bug reported by Michael Schierl in
15636 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15637 Jason Rumney's 2007-06-07 change worked around this bug, but
15639 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15641 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15643 * xdisp.c (start_display): If the character at POS is displayed
15644 via a display vector, reset IT->current.dpvec_index to zero.
15645 (try_window_reusing_current_matrix): If a line ends in a display
15646 vector or the next line starts in a display vector, continue
15647 redrawing the window even though the character position of
15648 start_row was reached.
15651 2011-10-18 Chong Yidong <cyd@gnu.org>
15653 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15654 with nobreak-char-display too.
15656 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15658 Fix part 3 of bug#9771.
15659 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15660 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15661 non-neutral characters if the current character is a paragraph
15662 separator (a.k.a. Newline). This avoids running the same
15663 expensive loop twice, once when we consume the preceding newline
15664 and the other time when the line actually needs to be displayed.
15665 Avoid the loop when we see neutrals on the base embedding level
15666 following a character whose directionality is the same as the
15667 paragraph's. This avoids running the expensive loop when a line
15668 ends in a long sequence of neutrals, like control characters.
15669 Add assertion against STRONG_AL type. Slightly rearrange code
15670 that determines the type of a neutral given the first non-neutral
15672 (bidi_level_of_next_char): Set next_en_pos to zero when
15673 invalidating its info.
15675 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15677 * xdisp.c (push_display_prop): Determine whether to record string
15678 or buffer position by IT->string, not by IT->method. Allow
15679 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15680 (move_it_vertically_backward): Don't look for character position
15681 immediately after the newline when in a continuation line.
15684 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15686 * window.c (coordinates_in_window): Rewrite and delabelize
15687 vertical border check. (Bug#5357) (Bug#9618)
15689 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15691 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15692 errors in XSetWindowBorder (bug#9310).
15694 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15696 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15697 avoid crash when xmalloc overrun checking is enabled.
15699 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15701 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15702 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15703 cursor motion with <left> and <right> arrow keys.
15705 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15706 some callers set that themselves.
15708 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15710 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15711 display string and the previous row comes from the same string and
15712 is empty. (Bug#9739) (Bug#9738)
15714 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15716 * doc.c (get_doc_string): Encode file name (bug#9735).
15718 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15720 * bidi.c (bidi_level_of_next_char):
15721 * xdisp.c (get_visually_first_element): Remove old incorrect
15722 comments regarding the Unicode Line Separator character.
15724 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15726 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15728 * alloc.c (Fgc_status): Do not access beyond zombies array
15729 boundary if nzombies > MAX_ZOMBIES.
15730 * alloc.c (dump_zombies): Add missing format specifier.
15732 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15734 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15735 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15737 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15738 Some packages use them to denote characters with modifiers.
15740 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15742 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15743 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15744 matching a pp-number. Rename parameter var to var1.
15746 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15748 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15750 2011-10-08 Glenn Morris <rgm@gnu.org>
15752 * callint.c (Fcall_interactively): Give a more explicit error for the
15753 'c' case with a non-character input. (Bug#8479)
15755 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15757 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15759 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15760 lines that are hscrolled on the left.
15762 * dispnew.c (buffer_posn_from_coords): Account for a possible
15763 presence of header-line. (Bug#4426)
15765 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15767 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15768 Don't advertise functionality which we discourage or doesn't work.
15770 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15772 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15773 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15774 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15775 this makes Emacs dump core during garbage collection on rare
15776 occasions. sizeof is obviously inferior to offsetof here, so
15777 stick with offsetof.
15778 (GC_POINTER_ALIGNMENT): New macro.
15779 (mark_memory): Omit 3rd (offset) arg; caller changed.
15780 Don't assume EMACS_INT alignment is the same as pointer alignment.
15782 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15784 * keyboard.c (read_key_sequence_remapped): New var.
15785 (read_key_sequence): Compute remapping in the right buffer.
15786 (command_loop_1): Use read_key_sequence's remapping directly.
15788 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15790 * dired.c (file_name_completion): Don't expand file name.
15791 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15792 before checking file name handler.
15794 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15795 they've been requested explicitly (bug#9591).
15797 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15799 * keymap.c (Fsingle_key_description): Use make_specified_string
15800 instead of build_string to build string from push_key_description.
15803 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15805 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15806 This fixes a Y2038 bug on 64-bit hosts.
15807 * buffer.c (reset_buffer):
15808 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15809 (Fclear_buffer_auto_save_failure):
15810 Use 0, not -1, to represent an unset failure time, since time_t
15811 might not be signed.
15813 Remove dependency on glibc malloc internals.
15814 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15815 Move back here from lisp.h, but with their new implementations.
15816 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15817 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15818 * charset.c (charset_table_init): New static var.
15819 (syms_of_charset): Use it instead of xmalloc. This removes a
15820 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15821 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15822 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15823 Move back to alloc.c.
15824 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15825 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15827 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15829 * nsterm.m (windowDidResize): Call x_set_window_size only when
15830 ns_in_resize is true. Otherwise set pixelwidth/height and
15831 call change_frame_size (Bug#9628).
15833 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15835 Port --enable-checking=all to Fedora 14 x86-64.
15836 * charset.c (syms_of_charset): Also account for glibc malloc's
15837 internal overhead when calculating the initial malloc maximum.
15839 Port --enable-checking=all to Fedora 14 x86.
15840 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15842 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15843 (overrun_check_realloc, overrun_check_free):
15844 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15845 That way, xmalloc returns a properly-aligned pointer even if
15846 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15847 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15848 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15849 into account when calculating the initial malloc maximum.
15850 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15851 Move here from alloc.c, so that charset.c can use it too.
15852 Properly align; the old code wasn't right for common 32-bit hosts
15853 when configured with --enable-checking=all.
15854 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15855 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15857 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15859 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15862 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15864 * xdisp.c (compute_display_string_end): If there's no display
15865 string at CHARPOS, return -1.
15867 * bidi.c (bidi_fetch_char): When compute_display_string_end
15868 returns a negative value, treat the character as a normal
15869 character not covered by a display string. (Bug#9624)
15871 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15873 * lread.c (Fread_from_string): Fix typo in docstring.
15875 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15877 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15878 newline, reseat the iterator instead of bidi-iterating there one
15879 character at a time. (Bug#9610)
15880 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15881 TO_CHARPOS if the bidi iterator is at base embedding level.
15883 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15885 * lread.c (readevalloop): Use correct code for NBSP.
15886 (read1): Likewise. (Bug#9608)
15888 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15890 * dbusbind.c (Fdbus_register_signal): When service is not
15891 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15893 2011-09-25 Glenn Morris <rgm@gnu.org>
15895 * buffer.c (truncate-lines): Doc fix.
15897 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15899 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15900 (Fset_window_next_buffers): Doc fix.
15902 2011-09-24 Glenn Morris <rgm@gnu.org>
15904 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15906 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15908 Fix minor problems found by static checking.
15909 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15910 * indent.c (Fvertical_motion): Fix == vs = typo.
15912 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15914 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15915 Default value is now t. Doc fix.
15917 * indent.c (Fvertical_motion): Compute and apply the overshoot
15918 logic when moving up, not only when moving down. Fix the
15919 confusing name and values of the it_overshoot_expected variable;
15920 logic changes accordingly. (Bug#9254) (Bug#9549)
15922 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15923 CHARPOS is covered by a display string which includes newlines.
15924 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15925 is covered by a display string with embedded newlines.
15927 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15929 * dbusbind.c (Fdbus_register_signal): Add match rule to
15930 Vdbus_registered_objects_table. (Bug#9581)
15931 (Fdbus_register_method, Vdbus_registered_objects_table):
15934 2011-09-24 Jim Meyering <meyering@redhat.com>
15936 do not ignore write error for any output size
15937 The previous change was incomplete.
15938 While it makes emacs --batch detect the vast majority of stdout
15939 write failures, errors were still ignored whenever the output size is
15940 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15941 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15942 && echo FAIL: ignored write error
15943 FAIL: ignored write error
15944 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15945 && echo FAIL: ignored write error
15946 FAIL: ignored write error
15947 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15949 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15951 * emacs.c (Fkill_emacs): In noninteractive mode exit
15952 non-successfully if a write error occurred on stdout. (Bug#9574)
15954 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15956 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15959 * dispextern.h (struct it): Update the comment documenting what
15962 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15964 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15965 a display string, extend search for cursor position to end of row.
15966 (find_row_edges): If the row ends in a newline from a display
15967 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15968 Handle the case of a display string with multiple newlines.
15969 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15970 non-empty line. Fixes confusing cursor motion with arrow keys at
15971 the beginning of a line that starts with whitespace.
15973 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15975 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15978 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15980 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15981 boolean (Bug#9154).
15983 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15985 * xdisp.c (display_line): Record maximum and minimum buffer
15986 positions even if no glyphs were produced (e.g., by a zero-width
15987 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15988 buffer positions that will be removed from the glyph row because
15990 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15991 column is beyond frame width: don't subtract 1 "pixel" when
15992 computing width of the stretch.
15993 (reseat_at_next_visible_line_start): Undo the change made on
15994 2011-09-17 that saved paragraph information and restored it after
15995 the call to `reseat'. (Bug#9545)
15997 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15999 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16000 and turn window cursor on if cleared (Bug#9415).
16002 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16004 * search.c (boyer_moore): Take unibyte characters from pattern
16005 literally. (Bug#9458)
16007 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16009 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16011 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16013 Fix minor problem found by static checking.
16014 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16015 initialized, to pacify gcc -Wuninitialized.
16017 * fileio.c: Report proper errno when syscall falls.
16018 (Finsert_file_contents): Save and restore errno,
16019 so that report_file_error outputs the correct diagnostic.
16020 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16022 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16024 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16026 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16028 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16029 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16031 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16033 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16034 about the current paragraph and restore it after the call to reseat.
16036 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16037 (bidi_find_paragraph_start): Search back for paragraph beginning
16038 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16039 (bidi_move_to_visually_next): Only trigger paragraph-related
16040 computations when the last character is a newline or at EOB, not
16041 just any NEUTRAL_B. (Bug#9470)
16043 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16044 truncated lines if point is covered by a display string. (Bug#9524)
16046 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16048 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16049 (cons_to_x_long): New function.
16050 (lisp_data_to_selection_data): Use it. Correct the test for
16051 short-versus-long data; it was negated. Break out of vector
16052 loop, for efficiency, when a long datum is discovered.
16054 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16056 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16058 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16060 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16061 GCC PR/17406) by declaring this function with external scope.
16063 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16065 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16066 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16068 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16070 * editfns.c (Fformat): Correctly handle text properties on "%%".

16076 * term.c (encode_terminal_code):
16077 * composite.c (composition_update_it, get_composition_id):
16078 * xdisp.c (get_next_display_element)
16079 (fill_composite_glyph_string): Add comments about special meaning
16080 of TAB characters in a composition.
16082 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16084 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16085 This occurs when processing a multibyte format.
16086 Problem reported by Wolfgang Jenker.
16088 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16090 * xdisp.c (try_cursor_movement): Only check for exact match if
16091 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16093 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16095 Remove unused external symbols.
16096 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16097 * xdisp.c (calc_pixel_width_or_height): Now static.
16098 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16099 * indent.c (check_display_width):
16100 * w32term.c: Fix comment to match code.
16101 * xterm.c, xterm.h (x_catching_errors): Remove.
16103 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16105 * xselect.c: Use signed conversions more consistently (Bug#9498).
16106 (selection_data_to_lisp_data): Assume incoming selection data are
16107 signed integers, not unsigned. This is to be consistent with
16108 outgoing selection data, which was modified to use signed integers
16109 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16110 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16111 expects long, not unsigned long.
16113 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16115 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16116 computation of loop end. Reported by Johan Bockgård
16119 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16121 * frame.c (Fother_visible_frames_p): Function deleted.
16123 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16125 * indent.c (compute_motion): Process display vector front to back
16126 rather than the other way around. (Bug#2496)
16128 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16130 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16132 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16134 * minibuf.c (Fread_from_minibuffer): Doc fix.
16136 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16138 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16139 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16141 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16143 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16144 value for non-existent files.
16146 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16148 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16149 set its "size" to -1. This will set the modtime_size field of
16150 the corresponding buffer to -1, which is what
16151 verify-visited-file-modtime expects for files that do not exist.
16154 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16156 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16158 * lisp.h: ... from here. push_key_description is no longer
16159 defined in keyboard.c, so its declaration should not be in
16160 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16161 logically belongs with push_key_description.
16163 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16165 * buffer.h: Include <sys/types.h> instead of <time.h>.
16166 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16167 Problem reported by Herbert J. Skuhra.
16169 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16171 * xml.c (parse_region): Make the parsing work for
16172 non-comment-starting XML files again (bug#9144).
16174 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16176 * image.c (gif_load): Fix calculation of bottom and right corner.
16179 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16181 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16182 redisplay in small windows.
16184 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16186 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16188 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16190 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16191 Operate on live windows only.
16193 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16195 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16197 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16199 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16200 only under bidi iteration.
16202 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16204 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16206 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16208 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16209 Without this fix, the command to link temacs failed due to an
16210 undefined symbol __builtin_isnan. This is because
16211 /usr/include/iso/math_c99.h #defines isnan(x) to
16212 __builtin_isnan(x), but the bundled gcc, which identifies itself
16213 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16215 * floatfns.c (isnan): #undef, and then #define to a clone of
16217 (Fisnan): Always define, since it's always available now.
16218 (syms_of_floatfns): Always define isnan at the Lisp level.
16220 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16222 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16224 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16226 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16227 The previous code assumed that file offsets (off_t values) fit in
16228 EMACS_INT variables, which is not true on typical 32-bit hosts.
16229 The code messed up by falsely reporting buffer overflow in cases
16230 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16231 when "big" contains more than 2**29 bytes, even though this
16232 inserts just one byte and does not overflow the buffer.
16233 (Finsert_file_contents): Store file offsets as off_t
16234 values, not as EMACS_INT values. Check for overflow when
16235 converting between EMACS_INT and off_t. When checking for
16236 buffer overflow or for overlap, take the offsets into account.
16237 Don't use EMACS_INT for small values where int suffices.
16238 When checking for overlap, fix a typo: ZV was used where
16239 ZV_BYTE was intended.
16240 (Fwrite_region): Don't assume off_t fits into 'long'.
16241 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16243 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16245 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16247 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16249 sprintf-related integer and memory overflow issues (Bug#9412).
16251 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16252 (esprintf, exprintf, evxprintf): New functions.
16253 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16254 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16255 (modify_event_symbol): Do not assume that the length of
16256 name_alist_or_stem is safe to alloca and fits in int.
16257 (Fexecute_extended_command): Likewise for function name and binding.
16258 (Frecursion_depth): Wrap around reliably on integer overflow.
16259 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16260 since some callers pass EMACS_INT values.
16261 (Fsingle_key_description): Don't crash if symbol name contains more
16262 than MAX_ALLOCA bytes.
16263 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16264 (get_minibuffer): Arg is now EMACS_INT, not int.
16265 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16266 (esprintf, exprintf, evxprintf): New decls.
16267 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16269 * dbusbind.c (signature_cat): New function.
16270 (xd_signature, Fdbus_register_signal):
16271 Do not overrun buffer; instead, report string overflow.
16273 * dispnew.c (add_window_display_history): Don't overrun buffer.
16274 Truncate instead; this is OK since it's just a log.
16276 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16277 even if the time zone offset is outlandishly large.
16278 Don't mishandle offset == INT_MIN.
16280 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16281 when creating daemon; the previous buffer-overflow check was incorrect.
16283 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16284 which has the guts of the old verror function.
16286 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16287 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16289 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16290 (font_unparse_xlfd): Don't blindly alloca long strings.
16291 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16292 fits in int, when using sprintf. Use single snprintf to count
16293 length of string rather than counting it via multiple sprintfs;
16294 that's simpler and more reliable.
16295 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16296 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16297 sprintf, in case result does not fit in int.
16299 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16300 (fontset_from_font): Print it.
16302 * frame.c (tty_frame_count): Now printmax_t, not int.
16303 (make_terminal_frame, set_term_frame_name): Print it.
16304 (x_report_frame_params): In X, window IDs are unsigned long,
16305 not signed long, so print them as unsigned.
16306 (validate_x_resource_name): Check for implausibly long names,
16307 and don't assume name length fits in 'int'.
16308 (x_get_resource_string): Don't blindly alloca invocation name;
16309 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16312 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16313 (xg_check_special_colors, xg_set_geometry):
16314 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16316 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16317 Use esprintf, not sprintf, in case result does not fit in int.
16319 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16320 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16321 it as a large positive number.
16322 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16323 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16325 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16326 in case result does not fit in int.
16328 * print.c (float_to_string): Detect width overflow more reliably.
16329 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16330 buffer overrun. Don't assume list length fits in 'int'. Treat
16331 print length of 0 as 0, not as infinity; to be consistent with other
16332 uses of print length in this function. Don't overflow print length
16333 index. Don't assume hash table size fits in 'long', or that
16334 vectorlike size fits in 'unsigned long'.
16336 * process.c (make_process): Use printmax_t, not int, to format
16337 process-name gensyms.
16339 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16341 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16342 to avoid potential buffer overrun.
16344 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16345 if X resource line is longer than 512 bytes.
16347 * xfns.c (x_window): Make sprintf buffer a bit bigger
16348 to avoid potential buffer overrun.
16350 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16352 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16354 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16356 Integer overflow fixes for scrolling, etc.
16357 Without these, Emacs silently mishandles large integers sometimes.
16358 For example, "C-u 4294967297 M-x recenter" was treated as if
16359 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16361 * xdisp.c (try_window_id): Check Emacs fixnum range before
16362 converting to 'int'.
16364 * window.c (window_scroll_line_based, Frecenter):
16365 Check that an Emacs fixnum is in range before assigning it to 'int'.
16366 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16367 values converted from Emacs fixnums.
16368 (Frecenter): Don't wrap around a line count if it is out of 'int'
16369 range; instead, treat it as an extreme value.
16370 (Fset_window_configuration, compare_window_configurations):
16371 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16373 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16374 that can exceed INT_MAX. Check that EMACS_INT value is in range
16375 before assigning it to the (possibly-narrower) index.
16376 (match_limit): Don't assume that a fixnum can fit in 'int'.
16378 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16381 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16382 (Fvertical_motion): Don't wrap around LINES values that don't fit
16383 in 'int'. Instead, treat them as extreme values. This is good
16384 enough for windows, which can't have more than INT_MAX lines anyway.
16386 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16388 * Require libxml/parser.h to avoid compilation warning.
16390 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16392 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16393 since this reportedly can destroy thread storage.
16395 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16397 * syntax.c (find_defun_start): Update all cache variables if
16398 exiting early (Bug#9401).
16400 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16402 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16404 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16405 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16406 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16408 * term.c (tty_append_glyph): New function.
16409 (produce_stretch_glyph): Static function and its prototype deleted.
16411 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16414 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16416 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16417 when checking :margin (Bug#9390).
16418 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16419 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16420 so that the name doesn't mislead. All uses changed.
16422 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16424 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16427 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16429 * xdisp.c (move_it_to): Don't bail out early when reaching
16430 position beyond to_charpos, if we are scanning backwards.
16431 (move_it_vertically_backward): When DY == 0, make sure we get to
16432 the first character in the line after the newline.
16434 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16436 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16437 (ccl_driver): Do not generate an out-of-range pointer.
16438 (Fccl_execute_on_string): Remove unnecessary check for
16439 integer overflow, noted by Stefan Monnier in
16440 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16441 Remove a FIXME that didn't need fixing.
16442 Simplify the newly-introduced buffer reallocation code.

16446 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16448 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16450 Integer and memory overflow issues (Bug#9196).
16452 * doc.c (get_doc_string): Rework so that
16453 get_doc_string_buffer_size is the actual buffer size, rather than
16454 being 1 less than the actual buffer size; this makes xpalloc more
16457 * image.c (x_allocate_bitmap_record, cache_image):
16458 * xselect.c (Fx_register_dnd_atom):
16459 Simplify previous changes by using xpalloc.
16461 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16462 since either will do and ptrdiff_t is convenient with xpalloc.
16464 * charset.c (charset_table_size)
16465 (struct charset_sort_data.priority): Now ptrdiff_t.
16466 (charset_compare): Don't overflow if priorities differ greatly.
16467 (Fsort_charsets): Don't assume list length fits in int.
16468 Check for size-calculation overflow when allocating sort data.
16469 (syms_of_charset): Allocate an initial charset table that is
16470 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16472 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16474 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16475 The actual value is always <= INT_MAX, and leaving it unsigned made
16476 overflow checking harder.
16478 * dispextern.h (struct glyph_matrix.rows_allocated)
16479 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16480 with xpalloc. The values are still always <= INT_MAX.
16482 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16484 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16485 (SAFE_NALLOCA): New macro.
16487 * region-cache.c (struct boundary.pos, find_cache_boundary)
16488 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16489 (set_cache_region, invalidate_region_cache)
16490 (revalidate_region_cache, know_region_cache, region_cache_forward)
16491 (region_cache_backward, pp_cache):
16492 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16493 so that ptrdiff_t * can be passed to xpalloc.
16494 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16495 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16496 (pp_cache): Don't assume cache_len fits in int.
16497 * region-cache.h: Adjust extern decls to match.
16499 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16500 EMACS_INT, since either will do, for xpalloc.
16502 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16503 (xnmalloc, xnrealloc, xpalloc): New functions.
16505 * bidi.c (bidi_shelve_header_size): New constant.
16506 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16507 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16509 * bidi.c (bidi_cache_shrink):
16510 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16512 Don't update size of array until after memory allocation succeeds,
16513 because xmalloc/xrealloc may not return.
16514 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16515 now that we have proper integer overflow checking.
16516 (record_overlay_string, overlay_strings): Catch overflows when
16517 calculating size of overlay_str_buf.
16519 * callproc.c (Fcall_process): Check for size overflow when
16520 calculating size of args2.
16521 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16522 Normally we prefer signed values, but sticking with ptrdiff_t would
16523 require adding more-complicated checks.
16525 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16526 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16527 Redo buffer-overflow calculations to avoid integer overflow.
16528 Add a FIXME comment where memory seems to be over-allocated.
16530 * character.c (Fstring): Check for size-calculation overflow.
16532 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16533 unnecessary integer overflow. Check for size overflow.
16534 (encode_coding_object): Don't update size until xmalloc succeeds.
16536 * composite.c (get_composition_id): Check for overflow in glyph
16537 length calculations.
16539 Integer and memory overflow fixes for display code.
16540 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16541 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16542 (scrolling_window): Check for overflow in size calculations.

16547 (scrolling_window): Avoid overflow in size calculations.
16548 Don't update size until allocation succeeds.
16549 * fns.c (concat): Check for overflow in size calculations.
16550 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16551 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

16554 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16555 (get_doc_string): Check for size calculation overflow.
16556 Don't update size until allocation succeeds.
16557 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16558 EMACS_INT, where ptrdiff_t will do.
16559 (Fsubstitute_command_keys): Check for string overflow.
16561 * editfns.c (set_time_zone_rule): Don't assume environment length
16563 (message_length): Now ptrdiff_t, not int.
16564 (Fmessage_box): Don't update size until allocation succeeds.
16565 Don't assume message length fits in int.
16566 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16568 * emacs.c (main): Do not reallocate argv, since there is a null at
16569 the end that can be overwritten, and this way there's no need to
16570 worry about size-calculation overflow.
16571 (sort_args): Check for size-calculation overflow.
16573 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16575 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16577 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16578 (x_set_scroll_bar_width, x_figure_window_size):
16579 Check for integer overflow.
16580 (x_set_alpha): Do not assume XINT fits in int.
16582 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16583 This is for the members text_lines, text_cols, total_lines, total_cols,
16584 where the system imposes an 'int' limit.
16586 * fringe.c (Fdefine_fringe_bitmap):
16587 Don't update size until alloc works.
16589 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16590 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16592 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16593 Check for size-calculation overflow.
16594 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16595 do, as we prefer signed integers.
16596 (id_to_widget.max_size, id_to_widget.used)
16597 (xg_store_widget_in_map, xg_remove_widget_from_map)
16598 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16599 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16600 Use and return ptrdiff_t, not int.
16601 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16602 * gtkutil.h: Change prototypes to match the above.
16604 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16605 are duplicate now that they've been promoted to lisp.h.
16606 (x_allocate_bitmap_record, x_alloc_image_color)
16607 (make_image_cache, cache_image, xpm_load):
16608 Don't update size until alloc is done.

16619 Use ptrdiff_t, not int, to count maps.
16620 (read_char_minibuf_menu_prompt): Check for overflow in size
16621 calculations. Don't update size until allocation succeeds.
16622 Redo calculations to avoid overflow.
16623 * keyboard.h: Change prototypes to match the above.
16625 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
16627 (current_minor_maps): Check for size calculation overflow.
16628 * keymap.h: Change prototypes to match the above.
16630 * lread.c (read1, init_obarray): Don't update size until alloc done.
16632 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

16635 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
16636 Now ptrdiff_t, not int.
16637 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

16649 (Fset_match_data): Don't assume list lengths fit in 'int'.
16651 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16652 for command line length. Do not attempt to address one before the
16653 beginning of an array, as that's not portable.
16655 * term.c (max_frame_lines): Remove; unused.
16656 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
16658 (encode_terminal_code, calculate_costs): Check for size
16659 calculation overflow.

16663 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
16665 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
16666 subtracting pointers.
16667 (gobble_line): Check for overflow more carefully. Don't update size
16670 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
16671 Don't update size until alloc done.
16672 Redo size calculations to avoid overflow.
16673 Check for size calculation overflow.

16681 Use ptrdiff_t, not int, for sizes.
16682 (Finternal_make_lisp_face, cache_face):
16683 Check for size calculation overflow.
16684 (cache_face): Treat size calculation overflows as if they were
16685 memory exhaustion (the usual treatment), rather than aborting.
16687 * xfns.c (x_encode_text, x_set_name_internal)
16688 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16689 sizes, since they can exceed INT_MAX in size. Check for size
16690 calculation overflow.
16692 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16693 (xg_select): Check for size calculation overflow.
16694 Don't update size until alloc done.
16696 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16697 as sprintf is limited to int lengths.
16699 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16700 (X_LONG_MIN): New macros.
16701 Use them to make the following changes clearer.
16702 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16703 This change doesn't affect the value now, but it may help remind
16704 future maintainers not to raise the value too much later.
16705 (SELECTION_QUANTUM): Remove, replacing with ...
16706 (selection_quantum): ... new function, which avoids overflow.
16708 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16709 assumption that selection length fits in 'int'.
16710 (x_reply_selection_request, x_handle_selection_request)
16711 (x_get_window_property, receive_incremental_selection)
16712 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
16713 (lisp_data_to_selection_data, clean_local_selection_data):
16714 Use ptrdiff_t, not int, to record length of selection.
16715 (x_reply_selection_request, x_get_window_property)

16717 Redo calculations to avoid overflow.
16718 (x_reply_selection_request): When sending hint, ceiling it at
16719 X_LONG_MAX rather than relying on wraparound overflow to send
16721 (x_get_window_property, receive_incremental_selection)
16722 (lisp_data_to_selection_data, x_property_data_to_lisp):
16723 Check for size-calculation overflow.
16724 (x_get_window_property, receive_incremental_selection)
16725 (lisp_data_to_selection_data, Fx_register_dnd_atom):
16726 Don't store size until memory allocation succeeds.
16727 (x_get_window_property): Plug memory leak on memory exhaustion.
16728 Don't double-block input; malloc is safe here. Don't assume 2**34
16729 - 4 fits in unsigned long. Add an xassert to check
16730 XGetWindowProperty overflow. Be more careful about overflow
16731 calculations, and distinguish size from memory overflow better.
16732 (receive_incremental_selection): When tracing, don't assume
16733 unsigned int is less than INT_MAX.
16734 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16735 harmful) conversions of unsigned short to int.
16736 (lisp_data_to_selection_data): Don't assume that integers
16737 in the range -65535 through -1 fit in an X unsigned short.
16738 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16739 result parameters unless successful. Rely on cons_to_unsigned
16740 to report problems with elements; the old code wasn't right anyway.
16741 (x_check_property_data): Check for int overflow; we cannot use
16742 a wider type due to X limits.
16743 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
16745 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
16747 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
16748 (x_term_init): Check for size calculation overflow.
16749 (x_color_cells): Don't store size until memory allocation succeeds.
16750 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
16751 Don't assume alloca size is less than MAX_ALLOCA.
16752 (x_term_init): Don't assume length fits in int (sprintf is limited
16755 Use ptrdiff_t for composition IDs.

16774 * image.c (xpm_get_color_table_h):
16775 * lisp.h (hash_lookup, hash_put):
16776 * minibuf.c (Ftest_completion):
16777 Use ptrdiff_t for hash table indexes, not int (which is too
16778 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16779 32-bit --with-wide-int hosts).
16781 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16782 Add a FIXME comment about memory leaks.
16783 (syms_of_charset): Don't assume xmalloc returns.
16785 Don't assume that stated character widths fit in int.
16786 * character.c (Fchar_width, c_string_width, lisp_string_width):
16787 * character.h (CHAR_WIDTH):
16788 * indent.c (MULTIBYTE_BYTES_WIDTH):
16789 Use sanitize_char_width to avoid undefined and/or bad behavior
16790 with outlandish widths.
16791 * character.h (sanitize_tab_width): Rename from sanitize_width,
16792 now that we have two such functions. All uses changed.
16793 (sanitize_char_width): New inline function.
16795 Don't assume that tab-width fits in int.
16796 * character.h (sanitize_width): New inline function.
16797 (SANE_TAB_WIDTH): New macro.
16798 (ASCII_CHAR_WIDTH): Use it.

16803 * fileio.c: Integer overflow issues with file modes.
16804 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
16806 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
16807 Remove unreachable code.

16810 * xterm.c: Don't go over XClientMessageEvent limit.
16811 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16812 (x_send_scroll_bar_event): Likewise. Check that the size does not
16813 exceed limits imposed by XClientMessageEvent, as well as the usual
16814 ptrdiff_t and size_t limits.
16816 * keyboard.c: Overflow, signedness and related fixes.
16817 (make_lispy_movement): Use same integer type in forward decl
16818 that is used in the definition.
16819 (read_key_sequence, keyremap_step):
16820 Change bufsize argument back to int, undoing my 2011-03-30 change.
16821 We prefer signed types, and int is wide enough here.
16822 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16823 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16824 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16825 length, not size_t. Use ptrdiff_t for index, not int.
16826 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16827 possibility of integer overflow.
16829 Overflow, signedness and related fixes for images.
16831 * dispextern.h (struct it.stack[0].u.image.image_id)
16832 (struct_it.image_id, struct image.id, struct image_cache.size)
16833 (struct image_cache.used, struct image_cache.ref_count):
16834 * gtkutil.c (update_frame_tool_bar):
16835 * image.c (x_reference_bitmap, Fimage_size, Fimage_mask_p)
16836 (Fimage_metadata, free_image_cache, clear_image_cache, lookup_image)
16837 (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
16838 * nsmenu.m (update_frame_tool_bar):
16839 * xdisp.c (calc_pixel_width_or_height):
16840 * xfns.c (image_cache_refcount):
16841 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
16842 on typical 64-bit hosts.

16850 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
16851 (lookup_image): Remove unnecessary tests.
16852 (xbm_image_p): Locals are now of int, not EMACS_INT,
16853 since parse_image_check makes sure they fit into int.
16854 (png_load, gif_load, svg_load_image):
16855 Prefer int to unsigned where either will do.
16856 (tiff_handler): New function, combining the cores of the
16857 old tiff_error_handler and tiff_warning_handler.
16858 This function is rewritten to use vsnprintf and thereby avoid
16859 stack buffer overflows. It uses only the features of vsnprintf
16860 that are common to both POSIX and native Microsoft.
16861 (tiff_error_handler, tiff_warning_handler): Use it.
16862 (tiff_load, gif_load, imagemagick_load_image):
16863 Don't assume :index value fits in 'int'.
16864 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16865 (imagemagick_load_image): Check that crop parameters fit into
16866 the integer types that MagickCropImage accepts. Don't assume
16867 Vimagemagick_render_type has a nonnegative value. Don't assume
16868 size_t fits in 'long'.

16944 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16945 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16946 candidate is selected by the mouse, and that candidate has a
16947 composed character under the mouse.
16949 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16950 coordinates reported by pos-visible-in-window-p for a composed

16961 composed buffer positions.
16963 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16965 * image.c (gif_load): Don't assume that each subimage has the same
16966 dimensions as the base image. Handle disposal method that is
16967 "undefined" by the gif spec (Bug#9335).

16978 from an Org mode buffer to a Speedbar frame.
16980 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16981 a composition, take its buffer position from IT->cmp_it.charpos.

16989 in a buffer produced by `describe-categories'.
16991 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16992 members before the level stack, so they would be saved and
16993 restored when copying iterator state. Fixes incorrect reordering
16994 around TABs covered by display properties.

17349 Without this fix, if a signal arrives just after memory fills up,
17350 'malloc' might be invoked reentrantly.
17352 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17353 In other words, assume that every image size is allowed, on non-X
17354 hosts. This assumption is probably wrong, but it lets Emacs compile.
17356 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17358 * regex.c (re_iswctype): Convert return values to boolean.
17360 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17362 * xdisp.c (compute_display_string_pos): Don't use cached display
17363 string position if the buffer had its restriction changed.
17366 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17368 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17370 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17372 Integer signedness and overflow and related fixes. (Bug#9079)
17374 * bidi.c: Integer size and overflow fixes.
17375 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17376 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17377 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17378 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17379 (bidi_find_other_level_edge):
17380 Use ptrdiff_t instead of EMACS_INT where either will do.
17381 This works better on 32-bit hosts configured --with-wide-int.
17382 (bidi_cache_ensure_space): Check for size-calculation overflow.
17383 Use % rather than repeated addition, for better worst-case speed.
17384 Don't set bidi_cache_size until after xrealloc returns, because it
17386 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17387 (bidi_cache_ensure_space): Also check that the bidi cache size
17388 does not exceed that of the largest Lisp string or buffer. See Eli
17389 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17391 * alloc.c (__malloc_size_t): Remove.
17392 All uses replaced by size_t. See Andreas Schwab's note
17393 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17395 * image.c: Improve checking for integer overflow.
17396 (check_image_size): Assume that f is nonnull, since
17397 it is always nonnull in practice. This is one less thing to
17398 worry about when checking for integer overflow later.
17399 (x_check_image_size): New function, which checks for integer
17400 overflow issues inside X.
17401 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17402 This removes the need for a memory_full check.
17403 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17404 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17405 (xbm_read_bitmap_data): Change locals back to 'int', since
17406 their values must fit in 'int'.
17407 (xpm_load_image, png_load, tiff_load):
17408 Invoke x_create_x_image_and_pixmap earlier,
17409 to avoid much needless work if the image is too large.
17410 (tiff_load): Treat overly large images as if
17411 x_create_x_image_and_pixmap failed, not as malloc failures.
17412 (gs_load): Use x_check_image_size.
17414 * gtkutil.c: Omit integer casts.
17415 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17416 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17418 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17420 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17421 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17422 would wrongly return t on a 64-bit host.
17424 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17425 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17426 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17427 and therefore cause GCC to emit a bogus diagnostic in some cases.
17429 * image.c: Integer signedness and overflow and related fixes.
17430 This is not an exhaustive set of fixes, but it's time to
17431 record what I've got.
17432 (lookup_pixel_color, check_image_size): Remove redundant decls.
17433 (check_image_size): Don't assume that arbitrary EMACS_INT values
17434 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17435 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17436 (tiff_load, imagemagick_load_image):
17437 Check for overflow in size calculations.
17438 (x_create_x_image_and_pixmap): Remove unnecessary test for
17439 xmalloc returning NULL; that can't happen.
17440 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17441 (xpm_color_bucket): Use better integer hashing function.
17442 (xpm_cache_color): Don't possibly over-allocate memory.
17443 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17444 (gif_memory_source):
17445 Use ptrdiff_t, not int or size_t, to record sizes.
17446 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17447 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17448 either works, as we prefer signed integers.
17449 (tiff_read_from_memory, tiff_write_from_memory):
17450 Return tsize_t, not size_t, since that's what the TIFF API wants.
17451 (tiff_read_from_memory): Don't fail simply because the read would
17452 go past EOF; instead, return a short read.
17453 (tiff_load): Omit no-longer-needed casts.
17454 (Fimagemagick_types): Don't assume size fits into 'int'.
17456 Improve hashing quality when configured --with-wide-int.
17457 * fns.c (hash_string): New function, taken from sxhash_string.
17458 Do not discard information about ASCII character case; this
17459 discarding is no longer needed.
17460 (sxhash-string): Use it. Change sig to match it. Caller changed.
17461 * lisp.h: Declare it.
17462 * lread.c (hash_string): Remove, since we now use fns.c's version.
17463 The fns.c version returns a wider integer if --with-wide-int is
17464 specified, so this should help the quality of the hashing a bit.
17466 * emacs.c: Integer overflow minor fix.
17467 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17468 Define only if GNU_LINUX.
17469 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17471 * dispnew.c: Integer signedness and overflow fixes.
17472 Remove unnecessary forward decls, that were a maintenance hassle.
17473 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17475 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17476 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17477 (prepare_desired_row, line_draw_cost):
17478 Use int, not unsigned, where either works.
17479 (save_current_matrix, restore_current_matrix):
17480 Use ptrdiff_t, not size_t, where either works.
17481 (init_display): Check for overflow more accurately, and without
17482 relying on undefined behavior.
17484 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17485 Remove, replacing with the new symbols in lisp.h. All uses changed.
17486 * fileio.c (make_temp_name):
17487 * filelock.c (lock_file_1, lock_file):
17488 * xdisp.c (message_dolog):
17489 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17490 Use pMd etc. instead.
17491 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17492 replacing the pWIDE etc. symbols removed from editfns.c.
17494 * keyboard.h (num_input_events): Now uintmax_t.
17495 This is (very slightly) less likely to mess up due to wraparound.
17498 * buffer.c: Integer signedness fixes.
17499 (alloc_buffer_text, enlarge_buffer_text):
17500 Use ptrdiff_t rather than size_t when either will do, as we prefer
17503 * alloc.c: Integer signedness and overflow fixes.
17504 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17505 (__malloc_size_t): Default to size_t, not to int.
17506 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17507 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17508 Prefer ptrdiff_t to size_t when either would do, as we prefer
17510 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17511 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17512 Now const. Initialize with values that are in range even if char
17514 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17515 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17516 These functions do the right thing with sizes > 2**32.
17517 (check_depth): Now ptrdiff_t, not int.
17518 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17519 Adjust to new way of storing sizes. Check for size overflow bugs
17521 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17522 slightly wrong anyway, as it missed one instance of
17523 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17524 (refill_memory_reserve): Omit needless cast to size_t.
17525 (mark_object_loop_halt): Mark as externally visible.
17527 * xselect.c: Integer signedness and overflow fixes.
17528 (Fx_register_dnd_atom, x_handle_dnd_message):
17529 Use ptrdiff_t, not size_t, since we prefer signed.
17530 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17531 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17532 x_dnd_atoms_size and x_dnd_atoms_length.
17534 * doprnt.c: Prefer signed to unsigned when either works.
17536 * doprnt.c (doprnt):
17538 * xdisp.c (vmessage):
17539 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17540 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17541 prefer signed arithmetic to avoid comparison confusion.
17542 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17543 but is a bit tricky.
17545 Assume freestanding C89 headers, string.h, stdlib.h.
17546 * data.c, doprnt.c, floatfns.c, print.c:
17547 Include float.h unconditionally.
17548 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17549 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17550 * regex.c: Likewise for stddef.h, string.h.
17551 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17552 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17553 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17554 (STDC_HEADERS): Remove obsolete defines.
17555 * sysdep.c: Include limits.h unconditionally.
17557 Assume support for memcmp, memcpy, memmove, memset.
17558 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17559 * regex.c (memcmp, memcpy):
17560 Remove; we assume C89 now.
17562 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17563 (__malloc_safe_bcopy): Remove; no longer needed.
17565 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17566 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17567 well either way, and we prefer signed to unsigned.
17569 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17571 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17572 closes the connection while we're reading (bug#9182).
17574 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17576 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17577 are specified (Bug#9168).
17579 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17581 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17582 Found by GCC static checking and --with-wide-int on a 32-bit host.
17584 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17586 * xdisp.c (compute_display_string_pos): Fix logic of caching
17587 previous display string position. Initialize cached_prev_pos to
17588 -1. Fixes slow-down at the beginning of a buffer.
17590 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17592 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17593 for attrs[LFACE_FONTSET_INDEX].
17595 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17597 * xml.c (parse_region): Remove unused local
17598 that was recently introduced.
17600 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17602 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17603 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17605 * xdisp.c (move_it_in_display_line_to): Record the best matching
17606 position for TO_CHARPOS while scanning the line, and restore it on
17607 exit if none of the characters scanned was an exact match.
17608 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17609 when exact match is impossible due to invisible text, and the
17610 lines are truncated.
17612 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17614 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17617 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17619 Fix a significant slow-down of cursor motion with C-n, C-p,
17620 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17621 auto-repeat under bidi redisplay in fontified buffers.
17622 * xdisp.c (compute_stop_pos_backwards): New function.
17623 (next_element_from_buffer): Call compute_stop_pos_backwards to
17624 find a suitable prev_stop when we find ourselves before
17626 (reseat): Don't look for prev_stop, as that could mean a very long
17628 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17629 <cached_disp_overlay_modiff>: Cache for last found display string
17631 (compute_display_string_pos): Return the cached position if asked
17632 about the same buffer in the same area of character positions, and
17633 the buffer wasn't changed since the time the display string
17634 position was cached.
17636 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17638 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17639 is an integer, which is important for empty lines. (Bug#9149)
17641 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17643 * frame.c (Fmodify_frame_parameters): In tty case, update the
17644 default face if necessary (Bug#4238).
17646 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17648 * editfns.c (Fstring_to_char): No need to explain what a character
17649 is in the docstring (Bug#6576).
17651 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17653 * xml.c (parse_region): Make sure we always return a tree.
17655 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17657 * xml.c (parse_region): If a document contains only comments,
17660 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17662 * xml.c (make_dom): Return comments, too.
17664 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17667 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17668 and the surrounding thread.
17669 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17670 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17671 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17673 * s/openbsd.h (BROKEN_SIGIO): Define.
17674 * unexelf.c (unexec) [__OpenBSD__]:
17675 Don't update the .mdebug section of the Alpha COFF symbol table.
17677 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17679 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17682 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17684 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17685 This fixes some race conditions on the permissions of any newly
17688 * alloc.c (valid_pointer_p): Use pipe, not open.
17689 This fixes some permissions issues when debugging.
17691 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17692 If fchown fails to set both uid and gid, try to set just gid,
17693 as that is sometimes allowed. Adjust the file's mode to eliminate
17694 setuid or setgid bits that are inappropriate if fchown fails.
17696 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17698 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17699 to compare Lisp_Objects.
17700 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17701 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17702 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17704 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17706 * lread.c (read_integer): Unread even EOF character.
17707 (read1): Likewise. Properly record start position of symbol.
17709 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17710 symbol character follows.
17712 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17714 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17715 This works around a problem with the previous change to Fcopy_file.
17716 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17717 and without this change, GCC might complain about discarding
17718 fchown's return value.
17720 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17722 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17724 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17726 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17728 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17730 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17731 it's used from the C level.
17733 * process.c: Use the same condition for POLL_FOR_INPUT in both
17734 keyboard.c and process.c (bug#1858).
17736 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17738 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17739 (Fgnutls_boot): Use it.
17741 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17743 * doc.c (Fsubstitute_command_keys): Revert last change.
17745 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17747 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17748 quotes the next character, and doesn't affect other longer
17749 sequences (bug#8935).
17751 * lread.c (syms_of_lread): Clarify that is isn't only
17752 `eval-buffer' and `eval-defun' that's affected by
17753 `lexical-binding' (bug#8460).
17755 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17757 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17758 bidi redisplay when a line includes both an image and is truncated.
17760 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17762 Fix minor problems found by static checking.
17763 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17764 (elsz): Now a signed constant, not a size_t var. We prefer signed
17765 types to unsigned, to avoid integer comparison confusion. Without
17766 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17767 "cannot optimize loop, the loop counter may overflow", a symptom
17769 * indent.c (Fvertical_motion): Mark locals as initialized.
17770 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17772 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17774 * search.c (Fre_search_backward): Mention `case-fold-search' in
17775 all the re_search_* functions (bug#8138).
17777 * keyboard.c (Fopen_dribble_file): Document when the file is
17780 2011-07-14 Eli Zaretskii <eliz@gnu.org>
17782 * bidi.c (bidi_dump_cached_states): Fix format of displaying
17785 Support bidi reordering of display and overlay strings.
17786 * xdisp.c (compute_display_string_pos)
17787 (compute_display_string_end): Accept additional argument STRING.
17788 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.

18298 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
18299 New macros, used in the buffer.c change.

18335 Random fixes. E.g., (random) never returned negative values.
18336 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18337 subseconds part to the entropy, as that's a bit more random.
18338 Prefer signed to unsigned, since the signedness doesn't matter and
18339 in general we prefer signed. When given a limit, use a
18340 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18341 latter isn't right if USE_2_TAGS_FOR_INTS.
18342 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18343 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18347 * textprop.c (text_property_stickiness):

18355 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18356 This is more efficient than Ffile_directory_p and avoids a minor race.

18360 * buffer.c (Foverlay_put): Say what the return value is
18363 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18364 is a directory before asking whether to use the file name
18366 (barf_or_query_if_file_exists): Make the "File is a directory"
18367 error be more correct.
18369 * fns.c (Frequire): Remove the mention of the .gz files, since
18370 that's installation-specific, but keep the mention of

18383 Qgnutls_bootprop_verify_error (which is no longer used).
18385 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18386 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18387 Also (re)move comments that are misplaced or no longer relevant.
18389 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
18391 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

18416 * lread.c (syms_of_lread): Mention single symbols defined by

18450 (syms_of_keymap): Defsubr make-composed-keymap.
18451 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

18488 * eval.c (struct backtrace): Simplify and port the data structure.
18489 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18490 signed bit field, as this assumption is not portable and it makes
18491 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18492 "char debug_on_exit : 1" as this is not portable either; instead,
18493 use the portable "unsigned int debug_on_exit : 1". Remove unused
18494 member evalargs. Remove obsolete comments about cc bombing out.
18496 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18666 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18667 for sizes. Check for string overflow more accurately.
18668 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
18670 * macros.c: Integer and buffer overflow fixes.
18671 * keyboard.h (struct keyboard.kbd_macro_bufsize):
18672 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
18673 Use ptrdiff_t, not int, for sizes.
18674 Don't increment bufsize until after realloc succeeds.
18675 Check for size-calculation overflow.
18676 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
18678 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
18680 * lread.c: Integer overflow fixes.
18681 (read_integer): Radix is now EMACS_INT, not int,
18682 to improve quality of diagnostics for out-of-range radices.
18683 Calculate buffer size correctly for out-of-range radices.
18684 (read1): Check for integer overflow in radices, and in
18685 read-circle numbers.
18686 (read_escape): Avoid int overflow.
18687 (Fload, openp, read_buffer_size, read1)
18688 (substitute_object_recurse, read_vector, read_list, map_obarray):
18689 Use ptrdiff_t, not int, for sizes.
18690 (read1): Use EMACS_INT, not int, for sizes.

18702 (read_escape): Check for hex character overflow.
18704 2011-06-22 Leo Liu <sdl.web@gmail.com>
18706 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
18707 Move to minibuffer.el.
18709 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18711 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18712 The following patches are for when GLYPH_DEBUG && !XASSERT.
18713 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18714 * dispnew.c (flush_stdout):
18715 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18716 Mark as externally visible.
18717 * dispnew.c (check_window_matrix_pointers): Now static.
18718 * dispnew.c (window_to_frame_vpos):
18719 * xfns.c (unwind_create_frame):
18720 * xterm.c (x_check_font): Remove unused local.
18721 * scroll.c (CHECK_BOUNDS):
18722 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18723 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18724 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18725 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18726 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18728 (debug_method_add): Use va_list and vsprintf rather than relying
18729 on undefined behavior with wrong number of arguments.
18730 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18731 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18732 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18733 since we're not interested in debugging glyphs with old libraries.
18734 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18735 GCC 4.6.0's static checking.
18737 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18739 Integer overflow and signedness fixes (Bug#8873).

18748 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
18749 (x_create_bitmap_from_xpm_data):
18750 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
18751 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
18753 * xfaces.c (load_pixmap):
18754 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
18755 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18756 (.bitmaps_last, struct x_output.icon_bitmap):
18757 Use ptrdiff_t, not int, for bitmap indexes.
18758 (x_allocate_bitmap_record): Check for size overflow.
18759 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18761 Use ptrdiff_t, not int, for overlay counts.
18762 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18763 * editfns.c (overlays_around, get_pos_property):
18764 * textprop.c (get_char_property_and_overlay):
18765 * xdisp.c (next_overlay_change, note_mouse_highlight):
18766 * xfaces.c (face_at_buffer_position):
18767 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18768 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18769 (Fnext_overlay_change, Fprevious_overlay_change)
18770 (mouse_face_overlay_overlaps, Foverlays_in):
18771 Use ptrdiff_t, not int, for sizes.
18772 (overlays_at, overlays_in): Check for size-calculation overflow.
18774 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18776 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18777 (x_session_initialize): Do not assume string length fits in int.
18779 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18780 This is unlikely, but can occur if DPI is outlandish.
18782 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18783 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18785 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18786 * xrdb.c (magic_file_p, search_magic_path):
18787 Omit last arg SUFFIX; it was always 0. All callers changed.
18788 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18790 * xfont.c (xfont_match): Avoid need for strlen.
18792 * xfns.c: Don't assume strlen fits in int.
18793 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18795 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18796 not unsigned long, as we prefer signed integers. All callers changed.
18797 Detect integer overflow in repeat count.
18798 (message_dolog): Don't assume print length fits in 39 bytes.
18799 (display_mode_element): Don't assume strlen fits in int.
18801 * termcap.c: Don't assume sizes fit in int and never overflow.
18802 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18803 (gobble_line): Check for size-calculation overflow.
18805 * minibuf.c (Fread_buffer):
18806 * lread.c (intern, intern_c_string):
18807 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18808 Don't assume string length fits in int.
18810 * keyboard.c (parse_tool_bar_item):
18811 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18813 * font.c: Don't assume string length fits in int.
18814 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18815 Use ptrdiff_t, not int.
18816 (font_intern_prop): Don't assume string length fits in int.
18817 Don't assume integer property fits in fixnum.
18818 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18820 * filelock.c: Fix some buffer overrun and integer overflow issues.
18821 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18822 Reformulate so as not to need the command string.
18823 Invoke gzip -cd rather than gunzip, as it's more portable.
18824 (lock_info_type, lock_file_1, lock_file):
18825 Don't assume pid_t and time_t fit in unsigned long.
18826 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18827 (current_lock_owner): Prefer signed type for sizes.
18828 Use memcpy, not strncpy, where memcpy is what is really wanted.
18829 Don't assume (via atoi) that time_t and pid_t fit in int.
18830 Check for time_t and/or pid_t out of range, e.g., via a network share.
18831 Don't alloca where an auto var works fine.
18833 * fileio.c: Fix some integer overflow issues.
18834 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18835 Don't assume string length fits in int.
18836 (directory_file_name): Don't assume string length fits in long.
18837 (make_temp_name): Don't assume pid fits in int, or that its print
18838 length is less than 20.
18840 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18842 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18844 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18846 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18847 We prefer signed integers, even for size calculations.
18849 * emacs.c: Don't assume string length fits in 'int'.
18850 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18851 (main): Don't invoke strlen when not needed.
18853 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18854 (XD_DEBUG_MESSAGE): Don't waste a byte.
18856 * callproc.c (getenv_internal_1, getenv_internal)
18857 (Fgetenv_internal):
18858 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18860 * lread.c (invalid_syntax): Omit length argument.
18861 All uses changed. This doesn't fix a bug, but it simplifies the
18862 code away from its former Hollerith-constant appearance, and it's
18863 one less 'int' to worry about when looking at integer-overflow issues.
18864 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18866 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18867 This didn't break anything, but it didn't help either.
18868 It's confusing to put a bogus integer in a place where the actual
18869 value does not matter.
18870 (LIST_END_P): Remove unused macro and its bogus comment.
18871 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18873 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18874 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18876 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18877 We prefer signed types, and the value cannot exceed the EMACS_INT
18878 range anyway (because otherwise the length would not be representable).
18879 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18880 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18881 This avoids a GCC warning when WIDE_EMACS_INT.
18883 * indent.c (sane_tab_width): New function.
18884 (current_column, scan_for_column, Findent_to, position_indentation)
18885 (compute_motion): Use it. This is just for clarity.
18886 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18888 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18890 * lisp.h (lint_assume): New macro.
18891 * composite.c (composition_gstring_put_cache):
18892 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18894 * editfns.c, insdel.c:
18895 Omit unnecessary forward decls, to simplify future changes.
18897 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18899 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18901 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18902 Use much-faster test for byte-length change.
18903 Don't assume string byte-length fits in 'int'.
18904 Check that character arg fits in 'int'.
18905 (mapcar1): Declare byte as byte, for clarity.
18907 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18909 * fns.c (concat): Catch string overflow earlier.
18910 Do not rely on integer wraparound.
18912 * dispextern.h (struct it.overlay_strings_charpos)
18913 (struct it.selective): Now EMACS_INT, not int.
18914 * xdisp.c (forward_to_next_line_start)
18915 (back_to_previous_visible_line_start)
18916 (reseat_at_next_visible_line_start, next_element_from_buffer):
18917 Don't arbitrarily truncate the value of 'selective' to int.
18919 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18921 * composite.c: Don't truncate sizes to 'int'.
18922 (composition_gstring_p, composition_reseat_it)
18923 (composition_adjust_point): Use EMACS_INT, not int.
18924 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18925 not EMACS_UINT, for indexes.
18927 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18929 * buffer.c: Include <verify.h>.
18930 (struct sortvec.priority, struct sortstr.priority):
18931 Now EMACS_INT, not int.
18932 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18933 (struct sortstr.size, record_overlay_string)
18934 (struct sortstrlist.size, struct sortlist.used):
18935 Don't truncate size to int.
18936 (record_overlay_string): Check for size-calculation overflow.
18937 (init_buffer_once): Check at compile-time, not run-time.
18939 2011-06-22 Jim Meyering <meyering@redhat.com>
18941 Don't leak an XBM-image-sized buffer
18942 * image.c (xbm_load): Free the image buffer after using it.
18944 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18947 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18948 that Sun C diagnosed.
18949 * fns.c (secure_hash): Fix pointer signedness issue.
18950 * intervals.c (static_offset_intervals): New function.
18951 (offset_intervals): Use it.
18953 2011-06-21 Leo Liu <sdl.web@gmail.com>
18956 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18959 * fns.c (secure_hash): Rename from crypto_hash_function and change
18960 the first arg to accept symbols.
18961 (Fsecure_hash): New primitive.
18962 (syms_of_fns): New symbols.
18964 2011-06-20 Deniz Dogan <deniz@dogan.se>
18966 * process.c (Fset_process_buffer): Clarify return value in
18969 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18971 * dispnew.c (add_window_display_history): Use BVAR.
18973 * xdisp.c (debug_method_add): Use BVAR.
18974 (check_window_end, dump_glyph_matrix, dump_glyph)
18975 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18977 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18980 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18981 check till after the cache is created in init_frame_faces.
18983 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18985 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18987 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18989 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18990 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18991 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18993 Improve buffer-overflow checking (Bug#8873).
18994 * fileio.c (Finsert_file_contents):
18995 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18996 Remove the old (too-loose) buffer overflow checks.
18997 They weren't needed, since make_gap checks for buffer overflow.
18998 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18999 The old code merely checked for Emacs fixnum overflow, and relied
19000 on undefined (wraparound) behavior. The new code avoids undefined
19001 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19003 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19004 Tune. Don't use wider integers than needed. Don't use alloca.
19005 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19007 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19009 * insdel.c, lisp.h (buffer_overflow): New function.
19010 (insert_from_buffer_1, replace_range, replace_range_2):
19011 * insdel.c (make_gap_larger):
19012 * editfns.c (Finsert_char):
19013 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19015 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19017 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19019 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19021 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19022 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19024 * fileio.c: Don't assume EMACS_INT fits in off_t.
19025 (emacs_lseek): New static function.
19026 (Finsert_file_contents, Fwrite_region): Use it.
19027 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19029 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19031 * fns.c: Don't overflow int when computing a list length.
19032 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19033 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19034 truncation on 64-bit hosts. Check for QUIT every
19035 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19036 faster and is responsive enough.
19037 (Flength): Report an error instead of overflowing an integer.
19038 (Fsafe_length): Return a float if the value is not representable
19039 as a fixnum. This shouldn't happen except in contrived situations.
19040 (Fnthcdr, Fsort): Don't assume list length fits in int.
19041 (Fcopy_sequence): Don't assume vector length fits in int.
19043 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19044 (header_size, word_size): New constants.
19045 (allocate_vectorlike): Don't check size overflow here.
19046 (allocate_vector): Check it here instead, since this is the only
19047 caller of allocate_vectorlike that could cause overflow.
19048 Check that the new vector's length is representable as a fixnum.
19050 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19051 The previous code was bogus. For example, next_almost_prime (32)
19052 returned 39, which is undesirable as it is a multiple of 3; and
19053 next_almost_prime (24) returned 25, which is a multiple of 5 so
19054 why was the code bothering to check for multiples of 7?
19056 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19058 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19060 Variadic C functions now count arguments with ptrdiff_t.
19061 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19062 Back then I didn't know that the Emacs coding style prefers signed int.
19063 Also, in the meantime I found a few more instances where arguments
19064 were being counted with int, which may truncate counts on 64-bit
19065 machines, or EMACS_INT, which may be unnecessarily wide.
19066 * lisp.h (struct Lisp_Subr.function.aMANY)
19067 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19068 Arg counts are now ptrdiff_t, not size_t.
19069 All variadic functions and their callers changed accordingly.
19070 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19071 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19072 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19073 * callint.c (Fcall_interactively): Check arg count for overflow,
19074 to avoid potential buffer overrun. Use signed char, not 'int',
19075 for 'varies' array, so that we needn't bother to check its size
19076 calculation for overflow.
19077 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19078 * eval.c (apply_lambda):
19079 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19080 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19081 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19083 * callint.c (Fcall_interactively): Don't use index var as event count.
19085 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19086 * mem-limits.h (SIZE): Remove; no longer used.
19088 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19090 Remove unnecessary casts.
19091 * xterm.c (x_term_init):
19092 * xfns.c (x_set_border_pixel):
19093 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19094 These aren't needed now that we assume ANSI C.
19096 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19097 It's more likely to cause problems (due to unsigned overflow)
19100 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19102 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19104 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19106 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19108 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19110 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19112 GLYPH_CODE_FACE returns EMACS_INT, not int.
19113 * dispextern.h (merge_faces):
19114 * xfaces.c (merge_faces):
19115 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19116 Don't assume EMACS_INT fits in int.
19118 * character.h (CHAR_VALID_P): Remove unused parameter.
19119 * fontset.c, lisp.h, xdisp.c: All uses changed.
19121 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19123 * fns.c (concat): Minor tuning based on overflow analysis.
19124 This doesn't fix any bugs. Use int to hold character, instead
19125 of constantly refetching from Emacs object. Use XFASTINT, not
19126 XINT, for value known to be a character. Don't bother comparing
19127 a single byte to 0400, as it's always less.
19129 * floatfns.c (Fexpt):
19130 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19132 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19135 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19137 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19138 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19139 incorrectly succeed when S was a string, because 4294967386 was
19140 truncated before it was used.
19142 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19143 Otherwise, an out-of-range integer could cause undefined behavior
19146 * composite.c: Use int, not EMACS_INT, for characters.
19147 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19148 EMACS_INT, for values that are known to be in character range.
19149 This doesn't fix any bugs but is the usual style inside Emacs and
19150 may generate better code on 32-bit machines.
19152 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19153 This is for reasons similar to the recent CHAR_STRING fix.
19154 * charset.c (Fencode_char): Check that character arg is actually
19155 a character. Pass an int to ENCODE_CHAR.
19156 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19157 wider than 'int', as a compile-time check to prevent future regressions
19160 * character.c (char_string): Remove unnecessary casts.
19162 Make sure a 64-bit char is never passed to CHAR_STRING.
19163 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19164 by silently ignoring the top 32 bits, allowing some values
19165 that were far too large to be valid characters.
19166 * character.h: Include <verify.h>.
19167 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19168 arguments are no wider than unsigned, as a compile-time check
19169 to prevent future regressions in this area.
19171 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19172 (Fsubst_char_in_region):
19174 * xdisp.c (decode_mode_spec_coding):
19175 Adjust to CHAR_STRING's new requirement.
19176 * editfns.c (Finsert_char, Fsubst_char_in_region):
19177 * fns.c (concat): Check that character args are actually
19178 characters. Without this test, these functions did the wrong
19179 thing with wildly out-of-range values on 64-bit hosts.
19181 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19182 These casts should not be needed on 32-bit hosts, either.
19183 * keyboard.c (read_char):
19184 * lread.c (Fload): Remove casts to unsigned.
19186 * lisp.h (UNSIGNED_CMP): New macro.
19187 This fixes comparison bugs on 64-bit hosts.
19188 (ASCII_CHAR_P): Use it.
19189 * casefiddle.c (casify_object):
19190 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19191 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19192 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19193 * dispextern.h (FACE_FROM_ID):
19194 * keyboard.c (read_char): Use UNSIGNED_CMP.
19196 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19197 not to EMACS_INT, to avoid GCC warning.
19199 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19201 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19202 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19203 isn't needed on 32-bit machines.
19205 * buffer.c (Fgenerate_new_buffer_name):
19206 Use EMACS_INT for count, not int.
19207 (advance_to_char_boundary): Return EMACS_INT, not int.
19209 * data.c (Qcompiled_function): Now static.
19211 * window.c (window_body_lines): Now static.
19213 * image.c (gif_load): Rename local to avoid shadowing.
19215 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19216 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19217 * alloc.c (make_save_value): Integer argument is now of type
19218 ptrdiff_t, not int.
19219 (mark_object): Use ptrdiff_t, not int.
19220 * lisp.h (pD): New macro.
19221 * print.c (print_object): Use it.
19223 * alloc.c: Use EMACS_INT, not int, to count objects.
19224 (total_conses, total_markers, total_symbols, total_vector_size)
19225 (total_free_conses, total_free_markers, total_free_symbols)
19226 (total_free_floats, total_floats, total_free_intervals)
19227 (total_intervals, total_strings, total_free_strings):
19228 Now EMACS_INT, not int. All uses changed.
19229 (Fgarbage_collect): Compute overall total using a double, so that
19230 integer overflow is less likely to be a problem. Check for overflow
19231 when converting back to an integer.
19232 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19233 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19234 These were 'int' variables that could overflow on 64-bit hosts;
19235 they were never used, so remove them instead of repairing them.
19236 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19237 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19238 Previously, this ceilinged at INT_MAX, but that doesn't work on
19240 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19242 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19243 (allocate_vectorlike): Check for ptrdiff_t overflow.
19244 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19245 when a (possibly-narrower) signed value would do just as well.
19246 We prefer using signed arithmetic, to avoid comparison confusion.
19248 * alloc.c: Catch some string size overflows that we were missing.
19249 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19250 for convenience in STRING_BYTES_MAX.
19251 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19252 The definition here is exact; the one in lisp.h was approximate.
19253 (allocate_string_data): Check for string overflow. This catches
19254 some instances we weren't catching before. Also, it catches
19255 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19256 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19257 and ptrdiff_t and EMACS_INT are both 64 bits.
19259 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19260 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19261 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19263 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19265 * alloc.c (Fmake_string): Check for out-of-range init.
19267 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19269 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
19271 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
19273 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
19274 xg_get_default_scrollbar_width.
19276 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
19277 (int_gtk_range_get_value): Move to the scroll bar part of the file.
19278 (style_changed_cb): Call update_theme_scrollbar_width and call
19279 x_set_scroll_bar_default_width and xg_frame_set_char_size for
19280 all frames (Bug#8505).
19281 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
19282 Call gtk_window_set_resizable if HAVE_GTK3.
19283 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
19284 and height if HAVE_GTK3 (Bug#8505).
19285 (scroll_bar_width_for_theme): New variable.
19286 (update_theme_scrollbar_width): New function.
19287 (xg_get_default_scrollbar_width): Move code to
19288 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
19289 (xg_initialize): Call update_theme_scrollbar_width.
19291 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
19293 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
19295 2011-06-12 Martin Rudalics <rudalics@gmx.at>
19297 * frame.c (make_frame): Call other_buffer_safely instead of
19300 * window.c (temp_output_buffer_show): Call display_buffer with
19301 second argument Vtemp_buffer_show_specifiers and reset latter
19302 immediately after the call.
19303 (Vtemp_buffer_show_specifiers): New variable.
19304 (auto_window_vscroll_p, next_screen_context_lines)
19305 (Vscroll_preserve_screen_position): Remove leading asterisks from

19488 Remove static from declaration of Qdelete_window, it's
19489 temporarily needed by Fbury_buffer.
19490 (replace_window): Don't assign orig_top_line and
19492 (Fdelete_window, delete_window): Remove. Window deletion is

19494 (window_loop): Remove DELETE_OTHER_WINDOWS case.
19495 Replace Fdelete_window calls with calls to Qdelete_window.
19496 (Fdelete_other_windows): Remove. Deleting other windows is

19856 (display_prop_intangible_p): Reimplement to call
19857 handle_display_spec instead of single_display_spec_intangible_p.

19869 value of a `display' property is a "replacing spec".
19870 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19871 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

19899 All callers changed. (Bug#8762)
19901 * gnutls.c: Use Emacs's memory allocators.
19902 Without this change, the gnutls library would invoke malloc etc.
19903 directly, which causes problems on non-SYNC_INPUT hosts, and which
19904 runs afoul of improving memory_full behavior. (Bug#8761)
19905 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19906 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19907 xfree instead of the default malloc, realloc, free.
19908 (Fgnutls_boot): No need to check for memory allocation failure,
19909 since xmalloc does that for us.
19911 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

19932 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19933 * alloc.c (allocate_vectorlike):
19934 Check for overflow in vector size calculations.
19935 * ccl.c (ccl_driver):
19936 Check for overflow when converting EMACS_INT to int.

19938 need to be updated by these changes.
19939 * fns.c (make_hash_table, maybe_resize_hash_table):
19940 Check for integer overflow with large hash tables.
19941 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19942 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19943 (SXHASH_REDUCE): New macro.
19944 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19945 Use it instead of discarding useful hash info with large hash values.
19946 (sxhash_float): New function.
19947 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19948 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19949 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19950 Rewrite to use FIXNUM_BITS, as this simplifies things.
19951 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19952 Adjust signatures to match updated version of code.
19953 (consing_since_gc): Now EMACS_INT, since a single hash table can
19954 use more than INT_MAX bytes.

19964 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19965 Call minibuffer-inactive-mode.
19967 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19969 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19970 Update dependencies.
19972 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19974 * data.c (init_data): Remove code for UTS, this system is not
19977 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19979 Don't force ./temacs to start in terminal mode.
19981 * frame.c (make_initial_frame): Initialize faces in all cases, not
19982 only when CANNOT_DUMP is defined.
19983 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19985 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19987 * dispnew.c (add_window_display_history): Use const for the string
19988 pointer. Remove declaration, not needed.
19990 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19992 Use 'inline', not 'INLINE'.
19993 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19994 * alloc.c, fontset.c (INLINE): Remove.
19995 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19996 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19997 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19998 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19999 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20001 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20003 Make it possible to run ./temacs.
20005 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20006 syms_of_callproc does the same thing. Remove test for
20007 "initialized", do it in the caller.
20008 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20010 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20012 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20013 (read_minibuf): Use get_minibuffer.
20014 (syms_of_minibuf): Use DEFSYM.
20015 (Qmetadata): New var.
20016 * data.c (Qbuffer): Don't make it static.
20017 (syms_of_data): Use DEFSYM.
20019 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20021 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20022 (CCL_CODE_MIN): New macro.
20024 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20026 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20028 * eval.c (Qdebug): Now static.
20029 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20030 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20031 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20033 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20035 * image.c: Various fixes to ImageMagick code comments.
20036 (Fimagemagick_types): Doc fix.
20038 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20040 Minor fixes prompted by GCC 4.6.0 warnings.
20042 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20044 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20045 (x_clipboard_manager_save_all): Move extern decl to ...
20046 * xterm.h: ... here, so that it can be checked for consistency.
20048 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20050 * xselect.c (x_clipboard_manager_save_frame)
20051 (x_clipboard_manager_save_all): New functions.
20052 (Fx_clipboard_manager_save): Lisp function deleted.
20054 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20055 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20057 * xterm.h: Update prototype.
20059 2011-05-28 William Xu <william.xwl@gmail.com>
20061 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20062 exiting (Bug#8239).
20064 2011-05-28 Jim Meyering <meyering@redhat.com>
20066 Avoid a sign-extension bug in crypto_hash_function.
20067 * fns.c (to_uchar): Define.
20068 (crypto_hash_function): Use it to convert some newly-signed
20069 variables to unsigned, to avoid sign-extension bugs. For example,
20070 without this change, (md5 "truc") would evaluate to
20071 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20072 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20073 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20075 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20077 Integer overflow fixes.
20079 * dbusbind.c: Serial number integer overflow fixes.
20080 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20081 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20082 to hold a serial number that is too large for a fixnum.
20083 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20084 Check for serial numbers out of range. Decode any serial number
20085 that was so large that it became a float. (Bug#8722)
20087 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20088 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20089 Use XFASTINT rather than XUINT when numbers are nonnegative.
20090 (xd_append_arg, Fdbus_method_return_internal):
20091 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20092 arguments, check that Lisp number is nonnegative, rather than
20093 silently wrapping negative numbers around. (Bug#8722)
20094 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20097 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20099 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20101 ccl: Add integer overflow checks.
20102 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20103 (IN_INT_RANGE): New macros.
20104 (ccl_driver): Use them to check for integer overflow when
20105 decoding a CCL program. Many of the new checks are whether XINT (x)
20106 fits in int; it doesn't always, on 64-bit hosts. The new version
20107 doesn't catch all possible integer overflows, but it's an
20108 improvement. (Bug#8719)
20110 * alloc.c (make_event_array): Use XINT, not XUINT.
20111 There's no need for unsigned here.
20113 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20114 This follows up to the 2011-05-06 change that substituted uintptr_t
20115 for EMACS_INT. This case wasn't caught back then.
20117 Rework Fformat to avoid integer overflow issues.
20118 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20119 now (part of C89). Include <verify.h>.
20120 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20121 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20122 (Fformat): Avoid the prepass trying to compute sizes; it was only
20123 approximate and thus did not catch overflow reliably. Instead, walk
20124 through the format just once, formatting and computing sizes as we go,
20125 checking for integer overflow at every step, and allocating a larger
20126 buffer as needed. Keep track separately whether the format is
20127 multibyte. Keep only the most-recently calculated precision, rather
20128 than them all. Record whether each argument has been converted to
20129 string. Use EMACS_INT, not int, for byte and char and arg counts.
20130 Support field widths and precisions larger than INT_MAX. Avoid
20131 sprintf's undefined behavior with conversion specifications such as %#d
20132 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20133 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20134 formatting out-of-range floating point numbers with int
20135 formats. (Bug#8668)
20137 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20139 * data.c: Avoid integer truncation in expressions involving floats.
20140 * data.c: Include <intprops.h>.
20141 (arith_driver): When there's an integer overflow in an expression
20142 involving floating point, convert the integers to floating point
20143 so that the resulting value does not suffer from catastrophic
20144 integer truncation. For example, on a 64-bit host (* 4
20145 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20146 Do not rely on undefined behavior after integer overflow.
20148 merge count_size_as_multibyte, parse_str_to_multibyte
20149 * character.c, character.h (count_size_as_multibyte):
20150 Rename from parse_str_to_multibyte; all uses changed.
20151 Check for integer overflow.
20152 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20153 since it's now a duplicate of the other. This is more of
20154 a character than a buffer op, so better that it's in character.c.
20155 * fns.c, print.c: Adjust to above changes.
20157 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20159 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20161 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20163 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20164 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20165 (x_clipboard_manager_save): Now static.
20166 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20168 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20169 (crypto_hash_function): Now static.
20170 Fix pointer signedness problems. Avoid unnecessary initializations.
20172 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20174 * termhooks.h (Vselection_alist): Make it terminal-local.
20176 * terminal.c (create_terminal): Initialize it.
20178 * xselect.c: Support for clipboard managers.
20179 (Vselection_alist): Move to termhooks.h as terminal-local var.
20180 (LOCAL_SELECTION): New macro.
20181 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20182 (symbol_to_x_atom): Remove gratuitous arg.
20183 (x_handle_selection_request, lisp_data_to_selection_data)
20184 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20185 (x_own_selection, x_get_local_selection, x_convert_selection):
20186 New arg, specifying work frame. Use terminal-local Vselection_alist.
20187 (some_frame_on_display): Delete unused function.
20188 (Fx_own_selection_internal, Fx_get_selection_internal)
20189 (Fx_disown_selection_internal, Fx_selection_owner_p)
20190 (Fx_selection_exists_p): New optional frame arg.
20191 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20192 (x_handle_selection_clear): Don't treat other terminals with the
20193 same keyboard specially. Use the terminal-local Vselection_alist.
20194 (x_clear_frame_selections): Use Frun_hook_with_args.
20196 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20198 * xterm.h: Add support for those atoms.
20200 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20202 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20203 (converted_selections, conversion_fail_tag): New global variables.
20204 (x_selection_request_lisp_error): Free the above.
20205 (x_get_local_selection): Remove unnecessary code.
20206 (x_reply_selection_request): Args changed; handle arbitrary array
20207 of converted selections stored in converted_selections.
20208 Separate the XChangeProperty and SelectionNotify steps.
20209 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20210 (x_convert_selection): New function.
20211 (x_handle_selection_event): Simplify.
20212 (x_get_foreign_selection): Don't ignore incoming requests while
20213 waiting for an answer; this will fail when we implement
20214 SAVE_TARGETS, and seems unnecessary anyway.
20215 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20216 (Vx_sent_selection_functions): Doc fix.
20218 2011-05-26 Leo Liu <sdl.web@gmail.com>
20220 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20222 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20224 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20226 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20227 for fringe update if it has periodic bitmap.
20228 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20229 and fringe_bitmap_periodic_p.
20231 * fringe.c (get_fringe_bitmap_data): New function.
20232 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20233 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20234 row. Mark glyph row for fringe update if periodicity changed.
20236 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20237 for fringe update unless it has periodic bitmap.
20239 2011-05-25 Kenichi Handa <handa@m17n.org>
20241 * xdisp.c (get_next_display_element): Set correct it->face_id for
20242 a static composition.
20244 2011-05-24 Leo Liu <sdl.web@gmail.com>
20247 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20249 * fns.c (crypto_hash_function, Fsha1): New function.
20250 (Fmd5): Use crypto_hash_function.
20251 (syms_of_fns): Add Ssha1.
20253 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20255 * gnutls.c: Remove unused macros.
20256 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20257 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20258 Remove macros that are defined and never used.
20259 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20261 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20263 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20264 (Fx_get_selection_internal): Minor cleanup.
20265 (Fx_own_selection_internal): Rename arguments for consistency with
20268 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20270 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20272 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20274 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20276 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20278 * dispnew.c (scrolling_window): Don't exclude the case that the
20279 last enabled row in the desired matrix touches the bottom boundary.
20281 2011-05-21 Glenn Morris <rgm@gnu.org>
20283 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20284 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20285 and add some more files.
20287 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20289 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20290 report_file_error introduced by the change from 2011-05-07.
20292 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20294 * systime.h (Time): Define only if emacs is defined.
20295 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20296 where the include path doesn't have X11/X.h by default. See
20297 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20299 2011-05-20 Kenichi Handa <handa@m17n.org>
20301 * composite.c (find_automatic_composition): Fix previous change.
20303 2011-05-20 Glenn Morris <rgm@gnu.org>
20305 * lisp.mk: New file, split from Makefile.in.
20306 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20307 (shortlisp): Remove.
20308 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20310 2011-05-19 Glenn Morris <rgm@gnu.org>
20312 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20313 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20314 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20315 (lisp): Set the order to that of loadup.el.
20316 (shortlisp): Make it a copy of $lisp.
20317 (SOME_MACHINE_LISP): Remove.
20318 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20319 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20321 2011-05-18 Kenichi Handa <handa@m17n.org>
20323 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20324 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20325 (find_automatic_composition): Mostly rewrite for efficiency.
20327 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20329 * makefile.w32-in: Update dependencies.
20331 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20333 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20334 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20336 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20338 Fix some integer overflow issues, such as string length overflow.
20340 * insdel.c (count_size_as_multibyte): Check for string overflow.
20342 * character.c (lisp_string_width): Check for string overflow.
20343 Use EMACS_INT, not int, for string indexes and lengths; in
20344 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20345 the resulting string length overflows an EMACS_INT; instead,
20346 report a string overflow if no precision given. When checking for
20347 precision exhaustion, use a check that cannot possibly have
20348 integer overflow. (Bug#8675)
20349 * character.h (lisp_string_width): Adjust to new signature.
20351 * alloc.c (string_overflow): New function.
20352 (Fmake_string): Use it. This doesn't change behavior, but saves
20353 a few bytes and will simplify future changes.
20354 * character.c (string_escape_byte8): Likewise.
20355 * lisp.h (string_overflow): New decl.
20357 Fixups, following up to the user-interface timestamp change.
20358 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20359 for UI timestamps, instead of unsigned long.
20360 * msdos.c (mouse_get_pos): Likewise.
20361 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20362 * w32gui.h (Time): Define by including "systime.h" rather than by
20363 declaring it ourselves. (Bug#8664)
20365 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20366 * image.c (clear_image_cache): Likewise.
20368 * term.c (term_mouse_position): Don't assume time_t wraparound.
20370 Be more systematic about user-interface timestamps.
20371 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20372 and sometimes 'EMACS_UINT', to represent these timestamps.
20373 This change causes it to use 'Time' uniformly, as that's what X uses.
20374 This makes the code easier to follow, and makes it easier to catch
20375 integer overflow bugs such as Bug#8664.
20376 * frame.c (Fmouse_position, Fmouse_pixel_position):
20377 Use Time, not unsigned long, for user-interface timestamps.
20378 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20379 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20380 * keyboard.h (last_event_timestamp): Likewise.
20381 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20382 * menu.h (xmenu_show): Likewise.
20383 * term.c (term_mouse_position): Likewise.
20384 * termhooks.h (struct input_event.timestamp): Likewise.
20385 (struct terminal.mouse_position_hook): Likewise.
20386 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20387 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20388 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20389 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20390 what it was before.
20391 * menu.h, termhooks.h: Include "systime.h", for Time.
20393 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20394 Don't assume that the difference between two unsigned long values
20395 can fit into an integer. At this point, we know button_down_time
20396 <= event->timestamp, so the difference must be nonnegative, so
20397 there's no need to cast the result if double-click-time is
20398 nonnegative, as it should be; check that it's nonnegative, just in
20399 case. This bug is triggered when events are more than 2**31 ms
20400 apart (about 25 days). (Bug#8664)
20402 * xselect.c (last_event_timestamp): Remove duplicate decl.
20403 (x_own_selection): Remove needless cast to unsigned long.
20405 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20406 that always fit in int. Use a sentinel instead of a counter, to
20407 avoid a temp and to allay GCC's concerns about possible int overflow.
20408 * frame.h (struct frame): Use int for menu_bar_items_used
20409 instead of EMACS_INT, since it always fits in int.
20411 * menu.c (grow_menu_items): Check for int overflow.
20413 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20415 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20416 Before, the code was not consistent. These values cannot exceed
20417 2**31 - 1 so there's no need to make them unsigned.
20418 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20419 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20420 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20422 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20424 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20425 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20426 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20427 presumably because the widths might not match.
20429 * window.c (size_window): Avoid needless test at loop start.
20431 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20433 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20435 2011-05-12 Drew Adams <drew.adams@oracle.com>
20437 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20439 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20441 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20442 `width' to `bar_area_x' and `bar_area_width', respectively.
20443 (x_scroll_run): Take account of fringe background extension.
20445 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20446 Rename local vars `left' and `width' to `bar_area_x' and
20447 `bar_area_width', respectively.
20448 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20449 background extension.
20451 2011-05-10 Jim Meyering <meyering@redhat.com>
20453 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20455 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20457 * image.c (Finit_image_library): Return t for built-in image types,
20458 like pbm and xbm. (Bug#8640)
20460 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20462 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20464 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20466 * w32console.c (Fset_screen_color): Doc fix.
20467 (Fget_screen_color): New function.
20468 (syms_of_ntterm): Defsubr it.
20470 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20471 unlink the temporary file if Fcall_process didn't create it in the
20473 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20474 child process will be redirected to a file specified with `:file'.
20475 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20476 cue to call_process_cleanup not to close that handle.
20478 2011-05-07 Ben Key <bkey76@gmail.com>
20480 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20481 one of two shell specific rules, either bootstrap-temacs-CMD or
20482 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20483 to the previous implementation of the bootstrap-temacs rule.
20484 The bootstrap-temacs-CMD rule is similar to the previous
20485 implementation of the bootstrap-temacs rule except that it
20486 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20489 These changes, along with some changes to nt/configure.bat,
20490 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20491 earlier fix to add support for --cflags and --ldflags options
20492 that include quotes so that it works whether make uses cmd or
20495 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20497 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20498 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20500 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20501 a string. Handle both cases.
20502 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20503 (Fdbus_register_method): Use Qinvalid_function.
20505 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20507 * makefile.w32-in: Update dependencies.
20508 (LISP_H): Add inttypes.h and stdin.h.
20509 (PROCESS_H): Add unistd.h.
20511 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20513 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20514 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20516 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20518 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20520 * term.c (vfatal): Remove stray call to va_end.
20521 It's not needed and the C Standard doesn't allow it here anyway.
20523 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20524 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20526 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20529 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20531 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20533 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20535 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20537 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20539 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20540 * charset.c (Fdefine_charset_internal): Don't initialize
20541 charset.code_space[15]. The value was garbage, on hosts with
20542 32-bit int (Bug#8600).
20544 * lread.c (read_integer): Be more consistent with string-to-number.
20545 Use string_to_number to do the actual conversion; this avoids
20546 rounding errors and fixes some other screwups. Without this fix,
20547 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20548 (digit_to_number): Move earlier, for benefit of read_integer.
20549 Return -1 if the digit is out of range for the base, -2 if it is
20550 not a digit in any supported base. (Bug#8602)
20552 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20554 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20555 to match comment at start of function. This also removes a
20556 GCC warning about overflow in a 32+64-bit port.
20558 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20560 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20561 Reported by Stefan Monnier in
20562 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20563 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20564 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20566 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20567 (EMACS_UINTPTR): Likewise, with uintptr_t.
20569 * lisp.h: Prefer 64-bit EMACS_INT if available.
20570 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20571 on 32-bit hosts that have 64-bit int, so that they can access
20573 However, temporarily disable this change unless the temporary
20574 symbol WIDE_EMACS_INT is defined.
20576 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20578 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20579 This removes an assumption that EMACS_INT and long are the same
20580 width as pointers. The assumption is true for Emacs porting targets
20581 now, but we want to make other targets possible.
20582 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20583 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20584 In the rest of the code, change types of integers that hold casted
20585 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20586 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20587 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20588 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20589 No need to cast type when ORing.
20590 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20591 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20592 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20593 assume EMACS_INT is the same width as char *.
20594 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20595 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20596 Remove no-longer-needed casts.
20597 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20598 (xg_tool_bar_help_callback, xg_make_tool_item):
20599 Use EMACS_INTPTR to hold an integer
20600 that will be cast to void *; this can avoid a GCC warning
20601 if EMACS_INT is not the same width as void *.
20602 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20603 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20604 (current_message_1, set_message_1):
20605 Use a local to convert to proper width without a cast.
20606 * xmenu.c (dialog_selection_callback): Likewise.
20608 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20609 Also, don't assume VALBITS / RAND_BITS is less than 5,
20610 and don't rely on undefined behavior when shifting a 1 left into
20612 * lisp.h (get_random): Change signature to match.
20614 * lread.c (hash_string): Use size_t, not int, for hash computation.
20615 Normally we prefer signed values; but hashing is special, because
20616 it's better to use unsigned division on hash table sizes so that
20617 the remainder is nonnegative. Also, size_t is the natural width
20618 for hashing into memory. The previous code used 'int', which doesn't
20619 retain enough info to hash well into very large tables.
20620 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20622 * dbusbind.c: Don't possibly lose pointer info when converting.
20623 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20624 Use XPNTR rather than XHASH, so that the high-order bits of
20625 the pointer aren't lost when converting through void *.
20627 * eval.c (Fautoload): Don't double-shift a pointer.
20629 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20631 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20633 * gnutls.c (DEF_GNUTLS_FN):
20634 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20636 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20638 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20641 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20643 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20644 New version that can reserve upto 2GB of heap space.
20646 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20648 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20650 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20652 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20653 `gnutls_certificate_set_x509_key_file'.
20655 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20657 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20658 Update dependencies.
20660 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20662 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20663 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20664 Remove unused parameter `fildes'.
20665 * process.c (read_process_output, send_process): Don't pass it.
20667 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20669 Fix previous change: the library cache is defined in w32.c.
20670 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20671 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20673 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20675 Implement dynamic loading of GnuTLS on Windows.
20677 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20678 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20679 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20682 * gnutls.c (Qgnutls_dll): Define.
20683 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
20684 (gnutls_*): Declare function pointers.
20685 (init_gnutls_functions): New function to initialize function pointers.
20686 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
20687 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
20688 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20689 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
20690 (emacs_gnutls_write, emacs_gnutls_read)
20691 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20692 (Fgnutls_available_p): New function.
20693 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
20694 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
20695 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
20697 * image.c: Include w32.h.
20698 (Vimage_type_cache): Delete.
20699 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
20700 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
20701 (w32_delayed_load): Move to w32.c.
20703 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20705 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20706 (w32_delayed_load): Move from image.c. When loading a library, record
20707 its filename in the :loaded-from property of the library id.
20708 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20709 Initialize and staticpro them.
20710 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20712 * process.c: Include lisp.h before w32.h, not after.
20713 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20714 instead of gnutls_record_check_pending.
20716 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20718 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20720 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20721 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20724 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20726 * xterm.c (x_set_frame_alpha): Do not set property on anything
20727 else than FRAME_X_OUTER_WINDOW (Bug#8608).

20747 * callproc.c: Indentation fixup.
20749 * sysdep.c (wait_for_termination_1): Make static.
20750 (wait_for_termination, interruptible_wait_for_termination):
20751 Move after wait_for_termination_1.
20753 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
20755 * sysdep.c (interruptible_wait_for_termination): New function
20756 which is like wait_for_termination, but allows keyboard
20759 * callproc.c (Fcall_process): Add (:file "file") as an option for
20761 (Fcall_process_region): Ditto.
20763 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20765 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20766 rather than `XVECTOR (FOO)->size'.
20768 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20769 inttypes.h, as a gnulib replacement is used if it not available in
20772 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20774 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20775 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20776 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20778 * coding.c (coding_alloc_by_realloc): Error out if destination
20779 will grow beyond MOST_POSITIVE_FIXNUM.
20780 (decode_coding_emacs_mule): Abort if there isn't enough place in

20793 * window.c (window_scroll_line_based): Use a marker instead of
20794 simple variables to record original value of point. (Bug#7952)
20796 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20797 produced by %s or %c overflows available buffer space. (Bug#8545)
20799 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20801 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20802 (SIZE_MAX): Move defn after all includes, as they might #define it.
20804 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20806 * w32.c (init_environment): Warn about defaulting HOME to C:\.

20826 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20828 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20830 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20832 * makefile.w32-in: Update dependencies.
20834 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20836 Improve `doprnt' and its usage. (Bug#8545)
20837 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20838 `format_end'. Remove support for %l as a conversion specifier.
20839 Don't use xrealloc. Improve diagnostics when the %l size modifier
20840 is used. Update the commentary.
20842 * eval.c (verror): Simplify calculation of size_t.
20844 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20847 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20849 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20852 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20854 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20855 This makes this file independent of the recent pseudovector change.
20857 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20859 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20861 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20862 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20863 Remove unused local.
20864 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20866 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20867 GCC 4.6.0 optimizes based on type-based alias analysis.
20868 For example, if b is of type struct buffer * and v of type struct
20869 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20870 != &v->size, and therefore "v->size = 1; b->size = 2; return
20871 v->size;" must therefore return 1. This assumption is incorrect
20872 for Emacs, since it type-puns struct Lisp_Vector * with many other
20873 types. To fix this problem, this patch adds a new type struct
20874 vectorlike_header that documents the constraints on layout of vectors
20875 and pseudovectors, and helps optimizing compilers not get fooled
20876 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20877 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20878 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20880 (XSETPVECTYPE): Rewrite in terms of new macro.
20881 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20882 This is a bit clearer, and further avoids the possibility of
20883 undesirable aliasing.
20884 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20885 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20886 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20887 since Lisp_Subr is a special case (no "next" field).
20888 (ASIZE): Now uses header.size rather than size.
20889 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20890 to avoid the hassle of writing XVECTOR (foo)->header.size.
20891 (struct vectorlike_header): New type.
20892 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20893 object, to help avoid aliasing.
20894 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20895 (SUBRP): Likewise, since Lisp_Subr is a special case.
20896 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20897 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20898 (struct Lisp_Hash_Table): Combine first two members into a single
20899 struct vectorlike_header member. All uses of "size" and "next" members
20900 changed to be "header.size" and "header.next".
20901 * buffer.h (struct buffer): Likewise.
20902 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20903 * frame.h (struct frame): Likewise.
20904 * process.h (struct Lisp_Process): Likewise.
20905 * termhooks.h (struct terminal): Likewise.
20906 * window.c (struct save_window_data, struct saved_window): Likewise.
20907 * window.h (struct window): Likewise.
20908 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20909 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20910 * buffer.c (init_buffer_once): Likewise.
20911 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20913 * process.c (Fformat_network_address): Use local var for size,
20916 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20918 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20919 * data.c (atof): Remove decl; no longer used or needed.
20920 (digit_to_number): Move to lread.c.
20921 (Fstring_to_number): Use new string_to_number function, to be
20922 consistent with how the Lisp reader treats infinities and NaNs.
20923 Do not assume that floating-point numbers represent EMACS_INT
20924 without losing information; this is not true on most 64-bit hosts.
20925 Avoid double-rounding errors, by insisting on integers when
20926 parsing non-base-10 numbers, as the documentation specifies.
20927 * lisp.h (string_to_number): New decl, replacing ...
20928 (isfloat_string): Remove.
20929 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20930 (read1): Do not accept +. and -. as integers; this
20931 appears to have been a coding error. Similarly, do not accept
20932 strings like +-1e0 as floating point numbers. Do not report
20933 overflow for integer overflows unless the base is not 10 which
20934 means we have no simple and reliable way to continue.
20935 Break out the floating-point parsing into a new
20936 function string_to_number, so that Fstring_to_number parses
20937 floating point numbers consistently with the Lisp reader.
20938 (digit_to_number): Move here from data.c. Make it static inline.
20939 (E_CHAR, EXP_INT): Remove, replacing with ...
20940 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20941 (string_to_number): New function, replacing isfloat_string.
20942 This function checks for valid syntax and produces the resulting
20943 Lisp float number too. Rework it so that string-to-number
20944 no longer mishandles examples like "1.0e+". Use strtoumax,
20945 so that overflow for non-base-10 numbers is reported only when
20946 there's no portable and simple way to convert to floating point.
20948 * textprop.c (set_text_properties_1): Rewrite for clarity,
20949 and to avoid GCC warning about integer overflow.
20951 * intervals.h (struct interval): Use EMACS_INT for members
20952 where EMACS_UINT might cause problems. See
20953 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20954 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20955 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20957 (offset_intervals): Tell GCC not to worry about length overflow
20958 when negating a negative length.
20960 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20961 (overrun_check_free): Likewise.
20963 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20964 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20967 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20968 (gnutls_make_error): Rename local to avoid shadowing.
20969 (gnutls_emacs_global_deinit): ifdef out; not used.
20970 (Fgnutls_boot): Use const for pointer to readonly storage.
20971 Comment out unused local. Fix pointer signedness problems.
20973 * lread.c (openp): Don't stuff size_t into an 'int'.
20974 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20975 about possible signed overflow.
20977 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20978 (GDK_KEY_g): Don't define if already defined.
20979 (xg_prepare_tooltip): Avoid pointer signedness problem.
20980 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20982 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20983 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20985 * xfns.c (Fx_window_property): Simplify a bit,
20986 to make a bit faster and to avoid GCC 4.6.0 warning.
20987 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20989 * fns.c (internal_equal): Don't assume size_t fits in int.
20991 * alloc.c (compact_small_strings): Tighten assertion a little.
20993 Replace pEd with more-general pI, and fix some printf arg casts.
20994 * lisp.h (pI): New macro, generalizing old pEd macro to other
20995 conversion specifiers. For example, use "...%"pI"d..." rather
20996 than "...%"pEd"...".
20997 (pEd): Remove. All uses replaced with similar uses of pI.
20998 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20999 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21000 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21001 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21002 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21003 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21004 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21006 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21007 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21008 * print.c (safe_debug_print, print_object): Likewise.
21009 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21011 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21012 avoiding the 0 flag, which is not portable.
21013 * process.c (Fmake_network_process): Use pI to avoid cast.
21014 * region-cache.c (pp_cache): Likewise.
21015 * xdisp.c (decode_mode_spec): Likewise.
21016 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21017 behavior on 64-bit hosts with printf arg.
21018 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21019 (x_stop_queuing_selection_requests): Likewise.
21020 (x_get_window_property): Don't truncate byte count to an 'int'
21023 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21024 here, since it parses constructs like leading '-' and spaces,
21025 which are not wanted; and it overflows with large numbers.
21026 Instead, simply match F[0-9]+, which is what is wanted anyway.
21028 * alloc.c: Remove unportable assumptions about struct layout.
21029 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21030 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21031 (allocate_vectorlike, make_pure_vector): Use the new macros,
21032 plus offsetof, to remove unportable assumptions about struct layout.
21033 These assumptions hold on all porting targets that I know of, but
21034 they are not guaranteed, they're easy to remove, and removing them
21035 makes further changes easier.
21037 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21038 This doesn't fix a bug but makes the code clearer.
21039 (string_overrun_cookie): Now const. Use initializers that
21040 don't formally overflow signed char, to avoid warnings.
21041 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21042 can cause Emacs to crash when string overrun checking is enabled.
21043 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21044 multiple of sizeof (EMACS_INT); it need not be, if
21045 alignof(EMACS_INT) < sizeof (EMACS_INT).
21046 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21048 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
21050 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
21052 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
21054 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
21055 supposed to be handshaking. (Bug#8556)
21056 Reported by Paul Eggert <eggert@cs.ucla.edu>.
21058 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
21060 * lisp.h (Qdebug): List symbol.
21061 * eval.c (Qdebug): Restore global linkage.

21063 (handle_user_signal): Break into debugger when debug-on-event
21064 matches the current signal symbol.
21066 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
21068 * alloc.c (check_sblock, check_string_bytes)
21069 (check_string_free_list): Convert to standard C.
21071 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
21073 * w32.c (emacs_gnutls_push): Fix typo.
21075 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21077 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21078 "cast to pointer from integer of different size".
21080 Improve doprnt and its use in verror. (Bug#8545)
21081 * doprnt.c (doprnt): Document the set of format control sequences
21082 supported by the function. Use SAFE_ALLOCA instead of always
21085 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21086 is one byte too soon. Don't use xrealloc; instead xfree and
21089 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21091 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21094 * gnutls.c: Renamed global_initialized to
21095 gnutls_global_initialized. Added internals for the
21096 :verify-hostname-error, :verify-error, and :verify-flags
21097 parameters of `gnutls-boot' and documented those parameters in the
21098 docstring. Start callback support.
21099 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21100 unless a fatal error occurred. Call gnutls_alert_send_appropriate
21101 on error. Return error code.
21102 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
21103 (emacs_gnutls_read): Likewise.
21104 (Fgnutls_boot): Return handshake error code.
21105 (emacs_gnutls_handle_error): New function.
21106 (wsaerror_to_errno): Likewise.

21161 changes in globals.h immediately force recompilation.
21162 (TAGS): Depend on $(CURDIR)/m/intel386.h and
21163 $(CURDIR)/s/ms-w32.h.

21168 <char-direction-table>: Deleted.
21170 2011-04-23 Eli Zaretskii <eliz@gnu.org>
21172 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
21173 * doprnt.c: Include limits.h.
21174 (SIZE_MAX): New macro.
21175 (doprnt): Return a size_t value. 2nd arg is now size_t.
21176 Many local variables are now size_t instead of int or unsigned.
21177 Improve overflow protection. Support `l' modifier for integer
21178 conversions. Support %l conversion. Don't assume an EMACS_INT
21179 argument for integer conversions and for %c.
21181 * lisp.h (doprnt): Restore prototype.
21183 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
21184 $(SRC)/character.h.
21186 * Makefile.in (base_obj): Add back doprnt.o.
21188 * deps.mk (doprnt.o): Add back prerequisites.
21189 (callint.o): Depend on character.h.
21191 * eval.c (internal_lisp_condition_case): Include the handler
21192 representation in the error message.
21193 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
21194 when breaking from the loop.
21196 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
21198 * callint.c (Fcall_interactively): When displaying error message
21199 about invalid control letter, pass the character's codepoint, not
21200 a pointer to its multibyte form. Improve display of the character
21201 in octal and display also its hex code.
21203 * character.c (char_string): Use %x to display the (unsigned)
21204 codepoint of an invalid character, to avoid displaying a bogus
21207 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21208 `error', not SYMBOL_NAME itself.
21210 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
21211 character arguments to `error'.
21213 * charset.c (check_iso_charset_parameter): Fix incorrect argument
21214 to `error' in error message about FINAL_CHAR argument. Make sure
21215 FINAL_CHAR is a character, and use %c when it is passed as
21216 argument to `error'.
21218 2011-04-23 Eli Zaretskii <eliz@gnu.org>

21406 ns_descriptor_to_entity that were caused by using free to
21407 deallocate memory blocks that were allocated by xmalloc (via
21408 xstrdup). This caused Emacs to crash when compiled with
21409 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with

21429 * process.c (send_process): Adjust to the new signatures of
21430 emacs_write and emacs_gnutls_write. Do not attempt to store

21756 * category.h: ... from here.
21757 * category.c (check_category_table, set_category_set): Now static.
21759 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
21760 * lisp.h: Remove these decls.
21762 * buffer.c (buffer_count): Remove unused var.
21764 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
21765 so that it's not optimized away.
21766 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
21767 * dispextern.h (bidi_dump_cached_states): Remove, since it's
21768 exported only to the debugger.
21770 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
21771 * atimer.h (run_all_atimers): Remove; not exported.
21773 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
21774 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
21775 was inaccessible from Lisp.
21776 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
21777 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
21779 alloc.c: Import and export fewer symbols, and remove unused items.
21780 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
21782 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
21783 it's not optimized away by whole-program optimization.
21784 (message_enable_multibyte, free_misc): Remove.
21785 (catchlist, handlerlist, mark_backtrace):
21786 Declare only if BYTE_MARK_STACK.
21787 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
21788 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.

21795 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
21796 (mark_backtrace): Define only if BYTE_MARK_STACK.
21797 * xdisp.c (message_enable_multibyte): Now static.
21799 Declare Lisp_Object Q* variables to be 'static' if not exported.
21800 This makes it easier for human readers (and static analyzers)
21801 to see whether these variables are used from other modules.
21802 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
21803 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
21804 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

21812 Remove decls of unexported vars.
21813 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21815 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21817 Make Emacs functions such as Fatom 'static' by default.
21818 This makes it easier for human readers (and static analyzers)
21819 to see whether these functions can be called from other modules.
21820 DEFUN now defines a static function. To make the function external
21821 so that it can be used in other C modules, use the new macro DEFUE.
21822 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21823 (Finit_image_library):
21824 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21825 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21826 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21827 Remove decls, since these functions are now static.
21828 (Funintern, Fget_internal_run_time): New decls, since these functions
21829 were already external.
21831 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21832 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

21839 Mark functions with DEFUE instead of DEFUN,
21840 if they are used in other modules.
21841 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21842 decls for now-static functions.
21843 * buffer.h (Fdelete_overlay): Remove decl.
21844 * callproc.c (Fgetenv_internal): Mark as internal.

21853 * image.c (Finit_image_library): New forward static decl.
21854 * insdel.c (Fcombine_after_change_execute): Make forward decl static.

21879 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21881 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21882 when at ZV. (Bug#8487)
21884 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21886 * charset.c (Fclear_charset_maps): Use xfree instead of free.

21889 * sound.c (sound_cleanup, alsa_close): Likewise.
21890 * termcap.c (tgetent): Likewise.
21891 * xfns.c (x_default_font_parameter): Likewise.
21892 * xsettings.c (read_and_apply_settings): Likewise.
21894 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21895 (overrun_check_free): Protoize.
21897 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21899 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21900 since callers should never pass a negative size.
21901 Change the signature to match that of plain 'read' and 'write'; see
21902 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21903 * lisp.h: Update prototypes of emacs_write and emacs_read.
21905 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21907 * xdisp.c (redisplay_window): Don't try to determine the character
21908 position of the scroll margin if the window start point w->startp
21909 is outside the buffer's accessible region. (Bug#8468)
21911 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21913 Fix write-region and its subroutines for buffers > 2GB.
21914 * fileio.c (a_write, e_write): Modify declaration of arguments and
21915 local variables to support buffers larger than 2GB.
21916 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21918 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21919 argument, local variables, and return value.
21921 * lisp.h: Update prototypes of emacs_write and emacs_read.
21923 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21925 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21927 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21929 Fix more problems found by GCC 4.6.0's static checks.
21931 * xdisp.c (vmessage): Use a better test for character truncation.
21933 * charset.c (load_charset_map): <, not <=, for optimization,
21934 and to avoid potential problems with integer overflow.
21935 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21936 * casetab.c (set_identity, shuffle): Likewise.
21937 * editfns.c (Fformat): Likewise.
21938 * syntax.c (skip_chars): Likewise.
21940 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21941 This also lets GCC 4.6.0 generate slightly better loop code.
21943 * callint.c (Fcall_interactively): <, not <=, for optimization.
21944 (Fcall_interactively): Count the number of arguments produced,
21945 not the number of arguments given. This is simpler and lets GCC
21946 4.6.0 generate slightly better code.
21948 * ftfont.c: Distingish more carefully between FcChar8 and char.
21949 The previous code passed unsigned char * to a functions like
21950 strlen and xstrcasecmp that expect char *, which does not
21951 conform to the C standard.
21952 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21953 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21954 char * when the C standard requires it.
21956 * keyboard.c (read_char): Remove unused var.
21958 * eval.c: Port to Windows vsnprintf (Bug#8435).
21959 Include <limits.h>.
21960 (SIZE_MAX): Define if the headers do not.
21961 (verror): Do not give up if vsnprintf returns a negative count.
21962 Instead, grow the buffer. This ports to Windows vsnprintf, which
21963 does not conform to C99. Problem reported by Eli Zaretskii.
21964 Also, simplify the allocation scheme, by avoiding the need for
21965 calling realloc, and removing the ALLOCATED variable.
21967 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21969 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21970 But keep the doprint source code for now, as we might revamp it
21971 and use it again (Bug#8435).
21972 * lisp.h (doprnt): Remove.
21973 * Makefile.in (base_obj): Remove doprnt.o.
21974 * deps.mk (doprnt.o): Remove.
21976 error: Print 32- and 64-bit integers portably (Bug#8435).
21977 Without this change, on typical 64-bit hosts error ("...%d...", N)
21978 was used to print both 32- and 64-bit integers N, which relied on
21979 undefined behavior.
21980 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21981 * lisp.h (error, verror): Mark as printf-like functions.
21982 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21983 Report overflow in size calculations when allocating printf buffer.
21984 Do not truncate output string at its first null byte.
21985 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21986 Truncate the output at a character boundary, since vsnprintf does not
21988 * charset.c (check_iso_charset_parameter): Convert internal
21989 character to string before calling 'error', since %c now has the
21991 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21992 overflow when computing char to be passed to 'error'. Do not
21993 pass Lisp_Object to 'error'; pass the integer instead.
21994 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21995 formatted with plain %d.
21997 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21999 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22001 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22003 * xterm.c (x_catch_errors): Remove duplicate declaration.
22005 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22007 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22009 2011-04-10 Jim Meyering <meyering@redhat.com>
22011 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22012 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22013 return ssize_t not "int", and use size_t as the buffer length.
22014 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22015 * gnutls.h: Update declarations.
22016 * process.c (read_process_output): Use ssize_t, to match.
22017 (send_process): Likewise.
22019 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22021 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22023 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22025 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22026 Use unsigned char, to match FcChar8 type definition.
22028 * xterm.c (handle_one_xevent):
22029 * xmenu.c (create_and_show_popup_menu):
22030 * xselect.c (x_decline_selection_request)
22031 (x_reply_selection_request): Avoid type-punned deref of X events.
22033 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22035 Fix some uses of `int' instead of EMACS_INT.
22036 * search.c (string_match_1, fast_string_match)
22037 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22038 (scan_buffer, find_next_newline_no_quit)
22039 (find_before_next_newline, search_command, Freplace_match)
22040 (Fmatch_data): Make some `int' variables be EMACS_INT.
22042 * xdisp.c (display_count_lines): 3rd argument and return value now
22043 EMACS_INT. All callers changed.
22044 (pint2hrstr): Last argument is now EMACS_INT.
22046 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22047 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22048 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

22059 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22060 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22062 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22063 (encode_invocation_designation): Last argument P_NCHARS is now
22065 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22066 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22068 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22071 * ccl.c (Fccl_execute_on_string): Declare some variables
22074 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22076 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22078 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22080 * process.c (Fformat_network_address): Doc fix.
22082 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22084 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22086 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22088 * keyboard.c (read_char): Call Lisp function help-form-show,
22089 instead of using internal_with_output_to_temp_buffer.
22090 (Qhelp_form_show): New var.
22091 (syms_of_keyboard): Use DEFSYM macro.
22093 * print.c (internal_with_output_to_temp_buffer): Function deleted.

22100 (list_processes_1): Delete.
22102 2011-04-06 Eli Zaretskii <eliz@gnu.org>
22104 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22106 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22108 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22110 Fix more problems found by GCC 4.6.0's static checks.
22112 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
22114 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22116 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22118 * xdisp.c (vmessage): Mark as a printf-like function.
22120 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
22122 * sound.c (sound_warning): Don't crash if arg contains a printf format.
22124 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
22125 printf-like functions.
22126 (tiff_load): Add casts to remove these marks before passing them
22127 to system-supplied API.
22129 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22131 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22132 This avoids several warnings with gcc -Wstrict-overflow.
22133 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22134 directly, rather than having caller test rule sign. This avoids
22135 some unnecessary tests.
22136 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22137 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22138 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22140 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22141 (xfont_open): Avoid unnecessary tests.
22143 * composite.c (composition_gstring_put_cache): Use unsigned integer.

22149 breaking out part of COMPOSITION_DECODE_RULE.
22150 (COMPOSITION_DECODE_RULE): Use it.
22151 * composite.c (get_composition_id): Remove unused local vars,
22152 by using the new macro.
22154 * textprop.c (set_text_properties_1): Change while to do-while,
22155 since the condition is always true at first.
22157 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22158 (interval_deletion_adjustment): Return unsigned value.
22161 * process.c (list_processes_1, create_pty, read_process_output):

22177 * print.c (print_error_message): Avoid int overflow.
22179 * font.c (font_list_entities): Redo for clarity,

22195 (wordify): Omit three unnecessary tests.
22197 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

22200 * casefiddle.c (casify_region): Remove var that is set but not used.
22202 * dired.c (file_name_completion): Remove var that is set but not used.
22204 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22206 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22207 (Finsert_file_contents): Remove unnecessary code checking fd.
22209 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22210 Check for integer overflow on size calculations.
22212 * buffer.c (Fprevious_overlay_change): Remove var that is set
22215 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22216 Remove vars that are set but not used.
22217 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22218 (timer_check_2): Mark vars as initialized.
22220 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22222 * image.c (lookup_image): Remove var that is set but not used.
22223 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22225 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22226 that are set but not used.
22228 * xfns.c (make_invisible_cursor): Don't return garbage
22229 if XCreateBitmapFromData fails (Bug#8410).
22231 * xselect.c (x_get_local_selection, x_handle_property_notify):
22232 Remove vars that are set but not used.
22234 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
22235 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
22237 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
22238 Remove var that is set but not used.
22239 (scroll_bar_windows_size): Now size_t, not int.
22240 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
22241 Check for overflow.
22243 * xfaces.c (realize_named_face): Remove vars that are set but not used.
22244 (map_tty_color) [!defined MSDOS]: Likewise.
22246 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22248 * coding.c: Remove vars that are set but not used.
22249 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22250 All callers changed.
22251 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22252 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22253 (decode_coding_charset): Remove vars that are set but not used.
22255 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22256 that is set but not used.
22258 * print.c (print_object): Remove var that is set but not used.
22260 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22261 The gnulib version avoids calling malloc in the usual case,
22262 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22263 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22264 * filelock.c (current_lock_owner): Likewise.
22265 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22266 * sysdep.c: Include allocator.h, careadlinkat.h.
22267 (emacs_no_realloc_allocator): New static constant.
22268 (emacs_readlink): New function.
22269 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22270 ../lib/careadlinkat.h.
22272 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22274 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22275 first non-nil return value).

22289 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22290 and thereabouts. All callers changed.
22291 (get_per_char_metric): Remove parameter `f', unused since
22292 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
22294 2011-04-02 Jim Meyering <meyering@redhat.com>
22296 do not dereference NULL upon failed strdup
22297 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22298 (ns_get_family): Likewise.
22300 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22302 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
22304 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
22306 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
22309 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
22311 Add lexical binding.
22313 * window.c (Ftemp_output_buffer_show): New fun.
22314 (Fsave_window_excursion):
22315 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
22317 * lread.c (lisp_file_lexically_bound_p): New function.
22318 (Fload): Bind Qlexical_binding.
22319 (readevalloop): Remove `evalfun' arg.
22320 Bind Qinternal_interpreter_environment.
22321 (Feval_buffer): Bind Qlexical_binding.
22322 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
22324 (syms_of_lread): Declare `lexical-binding'.
22326 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22328 * keyboard.c (eval_dyn): New fun.
22329 (menu_item_eval_property): Use it.
22331 * image.c (parse_image_spec): Use Ffunctionp.
22333 * fns.c (concat, mapcar1): Accept byte-code-functions.
22335 * eval.c (Fsetq): Handle lexical vars.
22336 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22337 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22338 (FletX, Flet): Obey lexical binding.
22339 (Fcommandp): Handle closures.
22340 (Feval): New `lexical' arg.
22341 (eval_sub): New function extracted from Feval. Use it almost
22342 everywhere where Feval was used. Look up vars in lexical env.
22344 (Ffunctionp): Move from subr.el.
22345 (Ffuncall): Handle closures.
22346 (apply_lambda): Remove `eval_flags'.
22347 (funcall_lambda): Handle closures and new byte-code-functions.
22348 (Fspecial_variable_p): New function.
22349 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22350 but without exporting it to Lisp.
22352 * doc.c (Fdocumentation, store_function_docstring):
22353 * data.c (Finteractive_form): Handle closures.
22355 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22358 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22360 (exec_byte_code): New function extracted from Fbyte_code to handle new
22361 calling convention for byte-code-functions. Add new byte-codes.
22363 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22365 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22367 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22369 * xdisp.c (redisplay_internal): Fix prototype.
22371 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22373 * xdisp.c (SCROLL_LIMIT): New macro.
22374 (try_scrolling): Use it when setting scroll_limit.
22375 Limit scrolling to 100 screen lines.
22376 (redisplay_window): Even when falling back on "recentering",
22377 position point in the window according to scroll-conservatively,
22378 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22380 (try_scrolling): When point is above the window, allow searching
22381 as far as scroll_max, or one screenful, to compute vertical
22382 distance from PT to the scroll margin position. This prevents
22383 try_scrolling from unnecessarily failing when
22384 scroll-conservatively is set to a value slightly larger than the
22385 window height. Clean up the case of PT below the margin at bottom
22386 of window: scroll_max can no longer be INT_MAX. When aggressive
22387 scrolling is in use, don't let point enter the opposite scroll
22388 margin as result of the scroll.
22389 (syms_of_xdisp) <scroll-conservatively>: Document the
22390 threshold of 100 lines for never-recentering scrolling.
22392 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22394 * dispextern.h (move_it_by_lines):
22395 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

22397 (message_log_check_duplicate): Remove parameters `prev_bol' and
22398 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22399 (redisplay_internal): Remove parameter `preserve_echo_area',
22400 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22402 * indent.c (Fvertical_motion):
22403 * window.c (window_scroll_pixel_based, Frecenter):
22404 Don't pass `need_y_p' to `move_it_by_lines'.
22406 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22408 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22409 steal a few bits to be more compact.
22410 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22411 Remove unneeded casts.
22413 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22415 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22417 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22418 binding" message (bug#7967).
22420 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22422 Fix more problems found by GCC 4.6.0's static checks.
22424 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22425 Remove unused local var.
22427 * editfns.c (Fmessage_box): Remove unused local var.
22429 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22430 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22431 Omit unused local vars.
22432 * window.c (shrink_windows): Omit unused local var.
22433 * menu.c (digest_single_submenu): Omit unused local var.
22434 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22435 Omit unused local var.
22437 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22438 Don't assume string length fits in int.
22439 (keyremap_step, read_key_sequence): Use size_t for sizes.
22440 (read_key_sequence): Don't check last_real_key_start redundantly.
22442 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22443 instead of alloca (Bug#8344).
22445 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22446 (Fbacktrace_frame): Don't assume nframes fits in int.
22448 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22450 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22453 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22455 * cm.c (calccost): Turn while-do into do-while, for clarity.
22457 * keyboard.c (syms_of_keyboard): Use the same style as later
22458 in this function when indexing through an array. This also
22459 works around GCC bug 48267.
22461 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22463 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22465 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22466 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22468 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22469 This avoids undefined behavior on integer overflow, and is a bit
22470 more convenient anyway since it is compared to a size_t variable.
22472 Variadic C functions now count arguments with size_t, not int.
22473 This avoids an unnecessary limitation on 64-bit machines, which
22474 caused (substring ...) to crash on large vectors (Bug#8344).

22484 * fns.c (concat): Likewise.
22485 * frame.c (x_set_frame_parameters): Likewise.
22486 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22487 0 if not found, not -1. All callers changed.
22489 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22490 (stack_copy_size): Now size_t, not int.
22491 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22493 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22495 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
22496 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22497 All callers changed.
22499 * lisp.h (multibyte_char_to_unibyte):
22500 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22501 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

22512 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22513 don't set the hook to nil, but remove the offending function instead.
22514 (Qcommand_hook_internal): Remove, unused.
22515 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22516 Vcommand_hook_internal.
22518 * eval.c (enum run_hooks_condition): Remove.
22519 (funcall_nil, funcall_not): New functions.
22520 (run_hook_with_args): Call each function through a `funcall' argument.

22534 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
22535 All callers changed.
22537 * w32.c (_wsa_errlist): Use braces for struct initializers.
22539 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

22686 * term.c (Fsuspend_tty, Fresume_tty):
22687 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22688 * window.c (temp_output_buffer_show):
22689 * insdel.c (signal_before_change):
22690 * frame.c (Fhandle_switch_frame):

22695 * callint.c (Fcall_interactively):
22696 * buffer.c (Fkill_all_local_variables):
22697 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22699 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22700 unconditionally since it does the check itself.
22702 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22704 Fix more problems found by GCC 4.5.2's static checks.
22706 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22707 the first time through the loop, since we know p0 < p1 then.
22708 This also avoids a gcc -Wstrict-overflow warning.
22710 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22711 leading to a memory leak, possible in functions like
22712 load_charset_map_from_file that can allocate an unbounded number
22713 of objects (Bug#8318).
22715 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22716 that could (at least in theory) be that large.
22718 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22719 This is less likely to overflow, and avoids undefined behavior if
22720 overflow does occur. All callers changed. Use strtoul to scan
22721 for the unsigned long integer.
22722 (pint2hrstr): Simplify and tune code slightly.
22723 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

22733 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22736 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22738 * process.c (Fmake_network_process): Use socklen_t, not int,
22739 where POSIX says socklen_t is required in portable programs.
22740 This fixes a porting bug on hosts like 64-bit HP-UX, where
22741 socklen_t is wider than int (Bug#8277).
22742 (Fmake_network_process, server_accept_connection):
22743 (wait_reading_process_output, read_process_output):
22746 * process.c: Rename or move locals to avoid shadowing.

22756 Make tparam.h and terminfo.c consistent.
22757 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22758 Include tparam.h instead, since it declares them.
22759 * cm.h (PC): Remove extern decl; tparam.h now does this.
22760 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22761 * terminfo.c: Include tparam.h, to check interfaces.
22762 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22763 (tparam): Adjust signature to match interface in tparam.h;
22764 this removes some undefined behavior. Check that outstring and len
22765 are zero, which they always are with Emacs.
22766 * tparam.h (PC, BC, UP): New extern decls.
22768 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22769 (xftfont_open): Rename locals to avoid shadowing.
22771 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

22783 * composite.c (composition_compute_stop_pos): Rename local to
22785 (composition_reseat_it): Remove unused locals.
22786 (find_automatic_composition, composition_adjust_point): Likewise.
22787 (composition_update_it): Mark var as initialized.
22788 (find_automatic_composition): Mark vars as initialized,
22789 with a FIXME (Bug#8290).

22793 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22794 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22795 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22796 to avoid shadowing.
22798 * textprop.c (property_change_between_p): Remove; unused.
22800 * intervals.c (interval_start_pos): Now static.
22802 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

22808 Fix pointer signedness.
22809 (alsa_choose_format): Remove unused local var.
22810 (wav_play): Initialize a variable to 0, to prevent undefined
22811 behavior (Bug#8278).
22813 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22815 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22817 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22818 clobbering (Bug#8298).
22819 * sysdep.c (sys_subshell): Likewise.
22820 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22822 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22823 This should get cleaned up, so that child_setup has the
22824 same signature on all platforms.
22826 * callproc.c (call_process_cleanup): Now static.
22827 (relocate_fd): Rename locals to avoid shadowing.
22829 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22831 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22832 not to be necessary, and produces flickering.
22834 2011-03-20 Glenn Morris <rgm@gnu.org>
22836 * config.in: Remove file.
22838 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
22840 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
22841 are now in src/globals.h.
22842 (syms_of_minibuf): Remove spurious & from previous change.

22868 (sigchld_handler): Now static.
22870 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
22871 That way, the code declares only the vars that it needs.

22883 Define only if needed.
22885 * unexelf.c (unexec): Name an expression,
22886 to avoid gcc -Wbad-function-cast warning.
22887 Use a different way to cause a compilation error if anyone uses
22888 n rather than nn, a way that does not involve shadowing.
22889 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22891 * deps.mk (unexalpha.o): Remove; unused.
22893 New file unexec.h, the (simple) interface for unexec (Bug#8267).

22968 ENABLE_CHECKING is not defined.
22970 * data.c (Findirect_variable): Name an expression, to avoid
22971 gcc -Wbad-function-cast warning.

23015 (WORDCHAR_P): Likewise. This one is never needed, but is used

23046 New macros, so that the caller can use some names other than
23047 gcpro1, gcpro2, etc.
23048 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23050 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23051 argument, for consistency with GCPRO2_VAR, etc: it is now the

23054 * dired.c (directory_files_internal, file_name_completion):
23055 Rename locals to avoid shadowing.
23057 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23058 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23059 dired.c's scmp function, had undefined behavior.
23060 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23061 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23062 * buffer.h: ... to here, because these macros use current_buffer,
23063 and the new implementation with inline functions needs to have
23064 current_buffer in scope now, rather than later when the macros
23066 (downcase, upcase1): New static inline functions.
23067 (DOWNCASE, UPCASE1): Reimplement using these functions.
23068 This avoids undefined behavior in expressions like
23069 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23070 from race conditions in accessing the global variables
23071 case_temp1 and case_temp2.
23072 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.

23099 so that gcc does not warn that these functions aren't declared.

23109 * buffer.c (fix_overlays_before): Mark locals as initialized.
23110 (fix_start_end_in_overlays): Likewise. This function should be
23111 simplified by using pointers-to-pointers, but that's a different
23113 (switch_to_buffer_1): Now static.
23114 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
23115 (report_overlay_modification): Rename locals to avoid shadowing.

23120 to suppress a gcc -Wclobbered warning that does not seem to be right.
23121 (MAXPATHLEN): Define only if needed.
23123 * process.c (serial_open, serial_configure): Move decls from here ...
23124 * systty.h: ... to here, so that they can be checked.
23126 * fns.c (get_random, seed_random): Move extern decls from here ...
23127 * lisp.h: ... to here, so that they can be checked.
23129 * sysdep.c (reset_io): Now static.
23130 (wait_for_termination_signal): Remove; unused.
23132 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

23136 (DENSE_TABLE_SIZE): Remove; unused.
23137 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
23138 (describe_map_tree):
23139 Rename locals to avoid shadowing.
23141 * keyboard.c: Declare functions static if they are not used elsewhere.

23483 -Wuninitialized does not deduce are never used uninitialized.
23484 (detect_coding_iso_2022): Initialize a local variable that might
23485 be used uninitialized. Leave a FIXME because it's not clear that
23486 this initialization is needed. (Bug#8211)
