3 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
4 garbaged only if it is not already the top frame on its TTY. This
5 prevents flickering due to constant redrawing of TTY frames when
6 there are GUI frames open in the same session. (Bug#13864)

42 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
43 This bug was introduced by my 2013-02-25 change that simplified
44 data_start configuration. Without this change, on GNU/Linux
45 an Emacs configured with --enable-profiling fails immediately
46 due to a profiler signal.
47 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
48 with these flags. On platforms where special flags are needed
49 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.

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

258 Use contents slot, not buffer, where appropriate.
259 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
260 to avoid deleted windows. Use contents slot instead of buffer.
261 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:

643 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
645 File synchronization fixes (Bug#13944).
646 * Makefile.in (LIB_FDATASYNC): New macro.

948 (create_lock_file, read_lock_data):
949 Prefer a symbolic link for the lock file, falling back on a
950 regular file if symlinks don't work. Do not try to create
951 symlinks on MS-Windows, due to security hassles. Stick with
952 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
953 link, rename, unlink, mkstemp) when creating locks, as a GNUish
954 host may be using a Windowsish file system, and cannot use
955 MS-Windows-only system calls. Fall back on mktemp if mkstemp
956 doesn't work. Don't fail merely because of a symlink-contents
957 length limit in the current file system; fall back on regular
958 files. Increase the symlink contents length limit to 8 KiB, this
959 should be big enough for any real use and doesn't crunch the
961 (create_lock_file, lock_file_1, read_lock_data):
962 Simplify allocation of lock file buffers now that they fit in 8 KiB.
963 (lock_file_1): Return error number, not bool. All callers changed.
964 (ELOOP): New macro, if not already defined.
965 (read_lock_data): Return size of lock file contents, not Lisp object.
966 All callers changed. Handle a race condition if some other process
967 replaces a regular-file lock with a symlink lock or vice versa,
968 while we're trying to read the lock.
969 (current_lock_owner): Parse contents more carefully, to help avoid
970 confusing a regular-file lock with some other application's use
971 of the file. Check for lock file contents being too long, or
972 not parsing correctly.
973 (current_lock_owner, lock_file):
974 Allow foreign pid and boot times that exceed the local range.
975 (current_lock_owner, lock_if_free, lock_file):
976 Simplify allocation of lock file contents.
977 * w32.c (sys_rename_replace): New function, containing most of
978 the contents of the old sys_rename.
979 (sys_rename): Use it.
980 (fchmod): New dummy function.
981 * w32.h (sys_rename_replace, fchmod): New decls.
983 2013-03-05 Eli Zaretskii <eliz@gnu.org>
985 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
986 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
987 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
988 <dmantipov@yandex.ru>.
990 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
992 * composite.c (get_composition_id, fill_gstring_header):
993 Use make_uninit_vector where appropriate.
994 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
995 * xselect.c (clean_local_selection_data): Likewise.
997 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
999 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1000 * image.c (imagemagick_load_image): Calculate height and width
1001 after flattening the image, not before.
1003 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1005 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1006 * ftfont.c (ftfont_shape_by_flt): Likewise.
1007 * w32uniscribe.c (uniscribe_shape): Likewise.
1009 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1011 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1012 The old approach, which fell back on DIR/.#FILE.0 through
1013 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1014 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1015 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1016 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1017 because the locking mechanism was never reliable in that case).
1018 This patch fixes this and other bugs discovered by a code
1019 inspection that was prompted by
1020 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1021 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1022 to avoid interoperability problems between the MS-Windows and
1023 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1024 instances of Emacs now ignore each others' locks.
1025 * filelock.c (defined_WINDOWSNT): New constant.
1026 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1027 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1028 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1029 regular files on MS-Windows hosts.
1030 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1031 Use SAFE_ALLOCA to avoid problems with long file names.
1032 (MAX_LFINFO): Now a local constant, not a global macro.
1033 (IS_LOCK_FILE): Remove.
1034 (lock_file_1): Don't inspect errno if symlink call succeeds;
1035 that's not portable.
1036 (lock_file): Document that this function can return if lock
1038 (lock_file): Don't access freed storage.
1040 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
1042 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
1044 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1046 * textprop.c: Use bool for booleans.
1047 (validate_interval_range, Fadd_text_properties)
1048 (Fremove_text_properties): Prefer bool to int when either works.
1050 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1052 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1053 If the interval tree changes as a side effect of calling
1054 modify_region, re-do processing starting from the call to
1055 validate_interval_range. (Bug#13743)
1057 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1059 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1062 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1064 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1065 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1066 access to the lock file until it is written and closed.
1069 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1071 * callint.c (Qcall_interactively):
1072 * macros.c (Qexecute_kbd_macro):
1075 2013-02-26 Bastien Guerry <bzg@gnu.org>
1077 * window.c (Frecenter): Tiny docstring enhancement.
1079 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1081 Minor textprop integer cleanup.
1082 * intervals.h, textprop.c (add_text_properties_from_list):
1083 Return void, not int, since nobody uses the return value.
1084 * textprop.c (validate_plist, add_properties, remove_properties)
1085 (Fadd_text_properties):
1086 Don't assume list length fits in int.
1087 (interval_has_all_properties, interval_has_some_properties)
1088 (interval_has_some_properties_list, add_properties, remove_properties)
1089 (Fadd_text_properties, Fremove_text_properties)
1090 (Fremove_list_of_text_properties, text_property_stickiness):
1091 Use bool for booleans.
1092 (Fadd_text_properties, Fremove_text_properties):
1093 (Fremove_list_of_text_properties):
1094 Reindent do-while as per GNU style.
1096 2013-02-25 Eli Zaretskii <eliz@gnu.org>
1098 Implement CLASH_DETECTION for MS-Windows.
1100 * filelock.c [WINDOWSNT]: Include w32.h.
1101 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1102 function of that name. Up-case the macro arguments.
1103 (IS_LOCK_FILE): New macro.
1104 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1105 (create_lock_file): New function, with body extracted from
1107 [WINDOWSNT]: Implement lock files by writing a regular file with
1108 the lock information as its contents.
1109 (read_lock_data): New function, on Posix platforms just calls
1111 [WINDOWSNT]: Read the lock info from the file.
1112 (current_lock_owner): Call read_lock_data instead of calling
1113 emacs_readlinkat directly.
1114 (lock_file) [WINDOWSNT]: Run the file name through
1117 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1118 just check if the process by that PID exists.
1120 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1121 also present, as doing so will fail to error out if the file
1124 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1126 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1127 (Fremove_list_of_text_properties): Skip all of the intervals in
1128 the region between START and END that already have resp. don't
1129 have the requested properties, not just the first one.
1130 Add assertions that the loop afterwards always modifies the
1131 properties. (Bug#13743)
1133 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1135 * callint.c (Fcall_interactively): Use the right lexical environment

1141 Simplify data_start configuration (Bug#13783).
1142 This is a followon simplification to the fix for Bug#13650.
1143 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
1144 (START_FILES): Remove. All uses removed.
1145 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
1146 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
1147 (buildobj.h): Use it.
1148 ($(ALLOBJS)): Depend on globals.h.
1149 (temacs$(EXEEXT)): Use $(ALLOBJS).
1150 * autodeps.mk (ALLOBJS): Move to Makefile.in.
1151 * deps.mk (vm-limit.o):
1152 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
1153 Do not depend on mem-limits.h.
1154 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
1155 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
1156 [__GNUC__ && !ORDINARY_LINK]: Remove.
1157 * mem-limits.h, pre-crt0.c: Remove.
1158 * unexaix.c, unexcoff.c: Don't include mem-limits.h.

1160 (make_hdr): Use DATA_START instead of start_of_data.
1161 * vm-limit.c: Move most of mem-limits.h's contents here.
1162 (data_start): New decl. It's OK if this is approximate,
1163 so simplify-away some unnecessary exactness.
1164 (POINTER): Remove; all uses removed.
1165 (data_space_start): Now char *, to avoid casts.
1166 (exceeds_lisp_ptr): New function, replacing the old
1167 EXCEEDS_LISP_PTR macro. All uses changed.
1168 (check_memory_limits): Simplify and remove casts.
1169 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.
1170 (memory_warnings): Use data_start instead of start_of_data.
1172 2013-02-24 Andreas Schwab <schwab@linux-m68k.org>
1174 * xdisp.c (set_message): Only check for debug-on-message if STRING
1175 is a string. (Bug#13797)
1177 2013-02-24 Paul Eggert <eggert@cs.ucla.edu>
1179 Fix regression introduced by July 10 filelock.c patch.
1180 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
1181 2012-07-10 patch to this file. Reported by Eli Zaretskii in
1182 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
1183 and diagnosed by Andreas Schwab in
1184 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
1186 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
1188 Assume C89 or better.
1189 * ralloc.c (SIZE, POINTER, NIL):
1190 * vm-limit.c (POINTER):
1191 Remove, replacing all uses with C89 equivalents. These old
1192 symbols were present only for porting to pre-C89 platforms.
1194 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1196 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
1197 This avoids warning messages reported as part of Bug#13546.

1203 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
1205 * sheap.c (report_sheap_usage): Prefer message1_nolog.
1207 * keyboard.c (Qcommand_execute): New var.
1208 (command_loop_1, read_char): Use it.
1209 (Fcommand_execute): Remove, replace by an Elisp implementation.

1212 2013-02-19 Daniel Colascione <dancol@dancol.org>
1214 * sheap.c (report_sheap_usage): Use message, not message1, so
1215 that we don't try to create a buffer while we're in the middle
1216 of dumping Emacs. Explain why.
1218 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
1220 * search.c (find_newline): Return byte position in bytepos.
1222 (find_next_newline_no_quit, find_before_next_newline):
1223 Add bytepos argument.
1224 * lisp.h (find_newline, find_next_newline_no_quit)

1230 (get_visually_first_element, move_it_vertically_backward):
1231 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
1233 2013-02-19 Eli Zaretskii <eliz@gnu.org>
1235 * w32proc.c (new_child): Avoid leaking handles if the subprocess
1236 resources were not orderly released.
1238 2013-02-17 Eli Zaretskii <eliz@gnu.org>
1240 * xdisp.c (x_draw_vertical_border): For a window that is neither
1241 the leftmost nor the rightmost, redraw both the left and the right
1242 vertical borders. (Bug#13723)
1244 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>

1257 2013-02-17 Jan Djärv <jan.h.d@swipnet.se>
1259 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...

1264 * w32.c (sys_chown): Remove unused function.
1266 * w32term.c <input_signal_count>: Declare 'volatile'
1267 unconditionally. (Bug#9066)
1269 * w32.c (set_errno): Reset h_errno and don't set it to any other
1270 value. Set errno instead.
1271 (check_errno): Reset h_errno.
1272 (sys_socket, socket_to_fd, sys_bind, sys_connect)
1273 (sys_gethostname, sys_getservbyname, sys_getpeername)
1274 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
1275 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set

1279 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>

1283 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1285 * keyboard.c (read_char): Fix calculation of auto-save time out
1286 when auto-save-timeout is less than 4. (Bug#13720)
1288 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
1289 time. Improve diagnostics in DebPrint. (Bug#13546)

1293 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
1294 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
1295 make sure errno is set to an appropriate value. (Bug#13546)
1296 (socket_to_fd): Add assertion against indexing fd_info[] with a
1297 value that is out of bounds.
1298 (sys_accept): If fd is negative, do not set up the child_process
1299 structure for reading.
1301 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
1303 * composite.c (fill_gstring_header): Remove useless prototype.

1315 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1317 Fix AIX port (Bug#13650).
1318 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1319 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1320 was #undeffed earlier, so it cannot be used as a macro here.
1321 Use the constant and not the macro.
1323 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1325 * w32proc.c (new_child): If no vacant slots are found in
1326 child_procs[], make another pass looking for slots whose process
1327 has exited or died. (Bug#13546)
1329 * w32.c (sys_pipe): When failing due to file descriptors above
1330 MAXDESC, set errno to EMFILE.
1331 (_sys_read_ahead): Update cp->status when failing to read serial
1332 communications input, so that the status doesn't stay at
1333 STATUS_READ_IN_PROGRESS. (Bug#13546)
1335 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1337 * gtkutil.c (tb_size_cb): New function.
1338 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
1340 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1342 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
1345 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
1347 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1349 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
1351 * font.c (font_range): Add pos_byte argument. Adjust comment
1352 and break long line.
1353 * font.h (font_range): Adjust prototype.
1354 * composite.c (autocmp_chars): Pass byte position to font_range.
1355 Break long line. Remove useless prototype and format comment.
1357 2013-02-13 Glenn Morris <rgm@gnu.org>
1359 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1361 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1363 Improve AIX port some more (Bug#13650).
1364 With this, it should be as good as it was in 23.3, though it's
1365 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1366 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1367 * unexaix.c (start_of_text): Remove.
1368 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1369 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1370 (orig_load_scnptr, orig_data_scnptr):
1371 Now off_t, not long, since they are file offsets.
1372 (make_hdr): Use _data, not start_of_data ().
1373 This is the key part of the fix.
1374 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1375 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1377 * pre-crt0.c (data_start): Initialize to 1.
1378 This ports to compilers that optimize the external declaration
1379 'int x = 0;' as if it were 'int x;' to shrink the executable.
1381 Improve AIX port (Bug#13650).
1382 This doesn't fix the bug, but it makes progress: Emacs builds now.
1383 * unexaix.c: Include inttypes.h, stdarg.h.
1384 (report_error, report_error_1): Mark as _Noreturn.
1385 (report_error): Don't report the wrong errno.
1386 (report_error_1): Now varargs. All callers changed.
1387 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1388 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1389 (write_ptr): Use %p to print address rather than %lx and a cast
1390 to unsigned long. Grow buffer a bit, to be safer.
1392 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1394 * bidi.c (bidi_resolve_neutral): After finding the next
1395 non-neutral character, accept NEUTRAL_ON type as well, because
1396 directional control characters, such as LRE and RLE, have their
1397 type converted to that by bidi_resolve_weak. This avoids aborts
1398 when LRE/RLE follows a run of neutrals.
1399 (bidi_move_to_visually_next): Assert that return value of
1400 bidi_peek_at_next_level is non-negative. Negative values will

1420 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1422 (display_line): Set w->region_showing to the value of
1423 it->region_beg_charpos, not to -1. This fixes redisplay
1424 optimization when cursor is moved up after M->. (Bug#13623)
1426 (try_scrolling): Scroll text up more if point is too close to ZV
1427 and inside the scroll margin. This makes sure point is moved
1428 outside the scroll margin in these cases.
1430 * window.h (struct window): region_showing can no longer be
1433 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>

1455 (active_maps): New function.
1456 (test_undefined): Also return true for nil bindings.
1457 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1458 a single (composed) keymap. Remember `first_event' to choose the right
1459 set of active keymaps. Recompute the set of keymaps after receiving
1460 the first event. Remove GOBBLE_FIRST_EVENT.
1461 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1462 * keyboard.h (read_char): Update declaration.
1463 * lread.c (read_filtered_event): Adjust call to read_char.
1465 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1467 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1468 Don't use the limitation on backwards movement when lines are truncated
1469 in the window. (Bug#13675)
1471 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1473 * marker.c (set_marker_internal): If desired position is passed
1474 as a marker, avoid call to buf_charpos_to_bytepos.
1475 * window.c (Fset_window_point): Omit redundant type checking.
1476 (Fset_window_start): Likewise. Format comment.
1477 (window_scroll_pixel_based): Use set_marker_restricted_both
1478 with character and byte positions obtained from an iterator.

1480 * xdisp.c (message_dolog): Likewise.
1482 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1484 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1485 When text lines are longer than window's screen lines, don't move back
1486 too far. This speeds up some redisplay operations. (Bug#13675)
1488 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1490 * syntax.c (scan_sexps_forward): Fix byte position calculation

1502 (sxhash_float): Return EMACS_UINT, for consistency with the other
1504 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1505 non-static inline function and therefore can't use static vars.
1506 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1507 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1508 with the other hash functions.
1510 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1512 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1513 XXXXXX part of the temporary file pattern is not downcased even
1514 when w32-downcase-file-names is non-nil. (Bug#13661)
1516 * xdisp.c (decode_mode_spec): Remove handling of %t.
1518 * msdos.c (careadlinkatcwd): Remove.
1520 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1522 * lread.c (skip_dyn_bytes): New function (bug#12598).

1559 * fns.c (Flocale_info): Likewise for ASET.
1560 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1561 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1563 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1565 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1568 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.

1573 (ns_last_use_native_fullscreen): New variable.
1574 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
1575 (x_set_window_size): Do not take title bar and tool bar into account
1576 if isFullscreen returns YES.
1577 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1578 (check_native_fs): New function.
1579 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.

1596 (syms_of_nsterm): Add ns-use-native-fullscreen.
1598 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1600 * fileio.c (Qchoose_write_coding_system): Now static.
1602 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1604 * xdisp.c (window_buffer_changed): region_showing can be negative,
1605 which still means region is being displayed.
1606 (redisplay_internal): Resurrect code that forced redisplay of the
1607 whole window when showing region and the mark has changed.
1608 Record the new mark position to allow redisplay optimizations.
1609 (display_line): If it->region_beg_charpos is non-zero, set the
1610 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1612 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1613 not bitfield of 1 bit.
1615 2013-02-03 Daniel Colascione <dancol@dancol.org>
1617 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1618 daemon mode works on cygw32 when Emacs is installed and not just
1621 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1623 Avoid file time stamp bug on MS-Windows (Bug#13149).
1624 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1625 as FAT32 doesn't update time stamps when truncating them.
1626 Also, check that a file time stamp is not a multiple of 100 ns;
1627 this should catch all instances of the problem on MS-Windows,
1628 as its native file system resolution is 100 ns or worse, and
1629 checking for a non-multiple of 100 ns should impose only a small
1630 overhead on systems with ns resolution.
1632 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1634 Avoid encoding file names on MS-Windows when they need to be run
1635 through dostounix_filename.
1636 * w32.c (normalize_filename): Accept an additional argument
1637 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1638 downcase it even if w32-downcase-file-names is non-nil.
1639 (dostounix_filename): Accept an additional argument MULTIBYTE and
1640 pass it to normalize_filename.
1641 (emacs_root_dir): Adjust.
1643 * msdos.h (dostounix_filename): Adjust prototype.
1645 * w32.h (dostounix_filename): Adjust prototype.
1647 * msdos.c (dostounix_filename): Accept an additional argument and
1649 (init_environment): Adjust callers of dostounix_filename.
1651 * fileio.c (Ffile_name_directory, file_name_as_directory)
1652 (directory_file_name, Fexpand_file_name)
1653 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1655 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1657 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1658 variables, as egetenv is case-insensitive for DOS_NT.
1660 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1661 with an encoded file name.
1663 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1664 Adjust calls to dostounix_filename.
1666 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1668 * unexw32.c (unexec): Adjust call to dostounix_filename.
1670 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1672 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1675 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1678 * callproc.c (Fcall_process): Make sure program name in PATH and
1679 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1680 is passed to exec/spawnve, which fails unless the file-name
1683 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1684 even if w32-quote-process-args is nil.
1686 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1688 Fix timestamp bug when write-region appends nothing (Bug#13149).
1689 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1690 the file's time stamp doesn't change if Emacs happens to write nothing
1691 to the file, and on a buggy file system this could cause Emacs to
1692 incorrectly infer that the file system doesn't have the bug.
1693 Avoid this problem by inhibiting the inference in this case.
1695 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1697 * window.h (struct window): Convert base_line_number, base_line_pos
1698 and column_number_displayed members from Lisp_Object to ptrdiff_t.

1702 (make_window): Initialize column_number_displayed.
1703 * print.c (print_object): Follow the printed representation of
1704 frames and print window pointer to distinguish between windows.

1708 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1709 (try_scrolling, try_cursor_movement, redisplay_window)
1710 (try_window_reusing_current_matrix, try_window_id, display_line)
1711 (display_mode_lines, decode_mode_spec): Adjust users.
1712 * .gdbinit (pwinx): Do not print sequence_number.
1714 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1716 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1717 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1718 * dired.c: Include <fcntl.h>.
1719 (open_directory): New function, which uses open and fdopendir
1720 rather than opendir. DOS_NT platforms still use opendir, though.

1722 (file_attributes): New function, with most of the old Ffile_attributes.
1723 (directory_files_internal, Ffile_attributes): Use it.
1724 (file_attributes, file_name_completion_stat): First arg is now fd,
1725 not dir name. All uses changed. Use fstatat rather than lstat +
1727 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1728 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1729 (emacs_readlinkat): New function, with much of the old
1730 Ffile_symlink_p, but with an fd argument for speed.
1731 It uses readlinkat rather than careadlinkatcwd, so that it
1732 need not assume the working directory.
1733 (Ffile_symlink_p): Use it.
1734 * filelock.c (current_lock_owner): Use emacs_readlinkat
1735 rather than emacs_readlink.
1736 * lisp.h (emacs_readlinkat): New decl.
1737 (READLINK_BUFSIZE, emacs_readlink): Remove.
1738 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1739 (emacs_norealloc_allocator, emacs_readlink): Remove.
1740 This stuff is moved to fileio.c.
1741 * w32.c (fstatat, readlinkat): New functions.
1742 (careadlinkat): Don't check that fd == AT_FDCWD.
1743 (careadlinkatcwd): Remove; no longer needed.

1755 (sys_close): Zero out the flags for the file descriptor before
1756 closing it. (Bug#13546)
1758 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1759 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1760 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1763 * w32.c (w32_get_long_filename, init_environment, readlink):
1764 Support file names encoded in DBCS codepages.
1765 (readlink): Use the current file-name-coding-system, not the ANSI
1766 codepage, to decode and handle targets of symlinks.
1768 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1770 * w32.c (opendir): Now accepts a 'const char *'.
1772 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>

1776 * dispnew.c (preemption_period, preemption_next_check): Remove.
1777 (Vredisplay_preemption_period): Likewise.
1778 (update_frame, update_single_window, update_window, update_frame_1):
1779 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1780 used, following the 2012-06-22 change.
1782 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1784 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1786 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1788 * font.c (num_fonts): Remove the leftover from old
1789 debugging code. Adjust comment style here and there.
1790 * insdel.c (insert_1): Remove.
1791 * lisp.h (insert_1): Remove prototype.
1792 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1794 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1796 * w32.c (max_filename_mbslen): New function.
1797 (normalize_filename, readdir): Use it to detect locales where ANSI
1798 encoding of file names uses a double-byte character set (DBCS).
1799 If a DBCS encoding is used, advance by characters using
1800 CharNextExA, instead of incrementing a 'char *' pointer.
1801 Use _mbslwr instead of _strlwr. (Bug#13515)
1803 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1804 request of memory reservation to 1.7GB. (Bug#13065)

1814 Avoid redundant calls to strlen.
1816 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1818 Drop async_visible and async_iconified fields of struct frame.
1819 This is possible because async input is gone; for details, see
1820 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1821 * frame.h (struct frame): Remove async_visible and async_iconified
1822 members, convert garbaged to unsigned bitfield. Adjust comments.
1823 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1824 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1825 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:

1827 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1829 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1830 properly. Likewise for obscured.

1840 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1842 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1844 * xdisp.c (message2, message2_nolog): Remove functions.
1845 (message3, message3_nolog): Extract nbytes and multibyteness directly
1846 from the string. Change all callers.
1847 (message3_nolog): Don't set message_enable_multibyte since set_message
1848 will reset it anyway.
1849 (message1, message1_nolog): Use message3.
1850 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1851 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1852 (set_message): Drop all but the second arg, which has to be a string.
1853 (set_message_1): Simplify now that we know that a1 is NULL and the
1854 second arg is a string.
1855 * frame.h (struct frame): Remove `message_buf' field.
1856 Use glyphs_initialized_p instead.
1857 (FRAME_MESSAGE_BUF): Remove macro.
1858 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1859 * lisp.h (message2, message2_nolog): Remove declarations.
1860 (message3, message3_nolog): Update declarations.
1861 * keyboard.c (read_char_minibuf_menu_text)
1862 (read_char_minibuf_menu_width): Remove vars.
1863 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1864 to correctly handle multibyte strings.
1865 * frame.c (delete_frame): Don't free message_buf any more.
1866 * editfns.c (message_text, message_length): Remove vars.
1867 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1868 * fileio.c (auto_save_error): Use message3 instead of message2.
1869 * dispnew.c (adjust_frame_message_buffer): Remove function.
1871 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1873 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1874 real estate used for the tool bar and the menu bar.
1876 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1878 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1879 hidden buffer is prepared to modification (Bug#13164).
1881 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1883 * window.h (struct window): Change window_end_valid member from
1884 Lisp_Object to a bitfield. Adjust comments.
1885 (wset_window_end_valid): Remove.
1886 * window.c (adjust_window_count): Clear window_end_valid.
1887 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1888 (Fwindow_line_height, set_window_buffer, Frecenter)
1889 (Fsplit_window_internal, Fdelete_other_windows_internal)
1890 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1891 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1892 * xdisp.c (check_window_end, reconsider_clip_changes)
1893 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1894 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1895 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1897 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1899 * xdisp.c (mark_window_display_accurate): Simplify the loop
1900 assuming that the only one of vchild, hchild or buffer window
1901 slots is non-nil. Call mark_window_display_accurate_1 for
1902 the leaf windows only.
1903 (mark_window_display_accurate_1): Always assume leaf window.
1906 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1908 * emacs.c (Qkill_emacs_hook): Now static.
1910 * fileio.c (Finsert_file_contents): Simplify.
1911 Remove unnecessary assignments and tests.
1913 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1915 * w32.c (acl_set_file): Don't test for errors unless
1916 set_file_security returns FALSE. Avoids spurious errors when
1919 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1921 * fileio.c (Finsert_file_contents): Revert code introduced at
1922 2013-01-18 in favor of the simpler and generally better fix.
1923 Save stack space by removing 'buffer' and reusing 'read_buf'
1926 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1928 * lisp.h (eabs): Define unconditionally (Bug#13419).
1929 The old "#if !defined (eabs)" was an unnecessary revenant of back
1930 when this macro was called "abs". Document 'eabs' better.
1932 2013-01-19 Glenn Morris <rgm@gnu.org>
1934 * fns.c (Frandom): Doc fix.
1936 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1938 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1939 segfault when there are lots of overlays.
1941 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1942 when there are lots of overlays.
1943 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1944 for the details and a way to reproduce.
1946 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1948 * fileio.c: Use O_APPEND to append.
1949 This corresponds better to the natural interpretation of "append",
1950 and avoids the need to open the output file twice, or to invoke
1951 lseek when APPEND is neither nil nor a number.
1952 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1953 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1954 file possibly twice, and lseeking to its end; this avoids the
1955 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1956 at the same time: the combination is never needed and apparently
1957 it doesn't work with DOS_NT.
1959 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1960 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1962 Allow floating-point file offsets.
1963 Problem reported by Vitalie Spinu in
1964 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1965 * fileio.c (emacs_lseek): Remove.
1966 (file_offset): New function.
1967 (Finsert_file_contents, Fwrite_region): Use it.
1969 2013-01-19 Chong Yidong <cyd@gnu.org>
1971 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1972 aborting on Fsignal (Bug#13289).
1974 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1976 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1977 set_file_security as failure due to insufficient privileges.
1978 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1979 (fstat): Return owner and group like 'stat' and 'lstat' do.
1981 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1983 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1984 The bug was observed on Ubuntu operating inside a virtual machine,
1985 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1986 The workaround introduces a race condition on non-buggy hosts,
1987 but it's an unlikely race and anyway there's a nearly identical
1988 nearby race that can't be fixed.
1989 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1991 (Fwrite_region): Test for file system time stamp bug.
1992 (init_fileio): New function.
1993 * lisp.h (init_fileio): Declare it.
1994 * emacs.c (main): Call it.
1996 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1997 and make it more consistent with other stat-failure diagnostics.
1999 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2001 Fix crash when inserting data from non-regular files.
2002 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2003 for the error description produced by valgrind.
2004 * fileio.c (read_non_regular): Rename to read_contents.
2005 Free Lisp_Save_Value object used to pass parameters.
2006 (read_non_regular_quit): Rename to read_contents_quit.
2007 (Finsert_file_contents): Redesign internal file reading loop to adjust
2008 gap and end positions after each read and so help make_gap to work
2009 properly. Do not signal an I/O error too early and so do not leave
2010 not yet decoded characters in a buffer, which was the reason of
2011 redisplay crash. Use list2 to build return value. Adjust comments.
2013 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2015 Close a race when statting and reading files (Bug#13149).
2016 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2017 This avoids a race if the file is renamed between stat and open.
2018 This race is not the problem originally noted in Bug#13149;
2019 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2021 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

2029 * alloc.c (format_save_value): Rename to make_save_value.
2030 (make_save_pointer): New function.
2031 (record_xmalloc): Use make_save_pointer.
2032 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2033 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2034 Change users of make_save_value to make_save_pointer.

2048 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2050 * keymap.c (map_keymap_internal): Use format_save_value.
2051 (map_keymap_char_table_item): Adjust accordingly.
2052 * fileio.c (non_regular_fd, non_regular_inserted)
2053 (non_regular_nbytes): Remove.
2054 (Finsert_file_contents): Convert trytry to ptrdiff_t.
2055 Use format_save_value to pass parameters to read_non_regular.
2056 (read_non_regular): Use XSAVE_ macros to extract parameters.
2058 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
2060 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
2062 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2064 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2065 extraction from any Lisp_Save_Value slot. Add type checking.
2066 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
2067 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
2068 * xselect.c: All users changed.
2070 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

2081 (save_excursion_restore): Use XSAVE_OBJECT.
2083 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
2085 Avoid needless casts with XSAVE_POINTER.
2086 * alloc.c (mark_object) [GC_MARK_STACK]:
2087 * dired.c (directory_files_internal_unwind):
2088 * fileio.c (do_auto_save_unwind):
2089 * gtkutil.c (pop_down_dialog):
2090 * keymap.c (map_keymap_char_table_item):
2091 * lread.c (load_unwind):
2092 * nsmenu.m (pop_down_menu):
2093 * print.c (print_object) [GC_MARK_STACK]:
2094 * xfns.c (clean_up_file_dialog):
2095 * xmenu.c (cleanup_widget_value_tree):
2096 Omit casts between XSAVE_POINTER and a pointer type.
2098 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>

2101 * eval.c (eval_sub): Protect `form' from being GCed before its
2102 car and cdr becomes protected with the backtrace entry.
2104 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2106 Make Lisp_Save_Value more versatile storage for up to four objects.
2107 * lisp.h (toplevel): Enumeration to describe types of saved objects.

2116 (free_save_value): Likewise.
2117 (mark_object): Likewise.
2118 * editfns.c (save_excursion_save): Pack everything within
2119 Lisp_Save_Value and so avoid xmalloc.
2120 (save_excursion_restore): Adjust to match new layout. Use free_misc
2121 because we do not allocate extra memory any more. Add eassert.
2122 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2123 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

2133 Bug#11484 with LCD smoothing on.
2135 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
2137 Fix SIGDANGER handlers, for AIX (Bug#13408).
2138 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
2139 Move handlers here from emacs.c; they were out of place.

2164 (nsfont_open): Move block_input earlier. Add unblock_input before early
2166 (nsfont_draw): Add block/unblock_input calls.
2168 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
2170 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs

2175 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
2176 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
2177 Clear tzvalbuf_in_environ if this workaround is in effect.
2178 Problem and fix reported by Kazuhiro Ito.
2180 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>

2189 string cross-reference(s).
2191 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
2193 Avoid unnecessary byte position calculation for the gap movement.
2194 Since all users of move_gap do CHAR_TO_BYTE for other purposes
2195 anyway, all of them should use move_gap_both instead.
2196 * lisp.h (move_gap): Remove prototype.
2197 * insdel.c (move_gap): Remove.
2198 (move_gap_both): Add eassert.

2205 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
2207 * term.c (init_tty): Use them instead of rolling our own code.
2208 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
2209 switches from 'signal' to 'pthread_sigmask', which is safer in
2210 multithreaded applications.
2211 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
2212 which has already arranged for that.
2213 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
2214 This is the main part of the bug fix.

2223 Omit buffer_slot_type_mismatch and use generic predicates to enforce
2224 the type of per-buffer values where appropriate.
2225 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
2226 predicate, which is how it's really used now. Adjust comment.
2227 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
2228 * buffer.c (buffer_slot_type_mismatch): Remove.
2229 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

2234 right-fringe-width, scroll-bar-width and buffer-display-count.
2235 Use Qstringp for default-directory, buffer-file-name,
2236 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
2237 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
2239 * data.c (store_symval_forwarding): Adjust to call the predicate.
2241 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
2243 * w32.c (get_name_and_id, acl_set_file):
2244 * w32term.c (w32fullscreen_hook): Remove unused local variables.

2254 * insdel.c (make_gap_larger): Use GAP_BYTES_DFL. Adjust comment.
2255 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
2256 (make_gap_1): New function to adjust the gap of any buffer.
2257 * coding.c (coding_alloc_by_making_gap): Use it.
2258 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
2259 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
2261 2013-01-08 Juri Linkov <juri@jurta.org>
2263 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
2264 of (supports :underline (:style wave)). (Bug#13000)

2280 (echo_char): Use it.
2281 (read_key_sequence): When echoing mock input, ensure that the
2282 trailing dash is properly added.
2284 2013-01-05 Eli Zaretskii <eliz@gnu.org>
2286 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
2287 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
2288 digits for buffer positions, before misalignment starts.
2289 Display "0" for integer "object" field.
2290 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2291 Display the newline glyph more unambiguously.
2293 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2295 * nsterm.m (ns_draw_underwave):
2296 * w32term.c (w32_draw_underwave):
2297 * xterm.c (x_draw_underwave): Make underwave look more triangular

2300 * nsterm.m (ns_draw_text_decoration):
2301 * w32term.c (x_draw_glyph_string):
2302 * xterm.c (x_draw_glyph_string): Don't use previous underline
2303 thickness and position if previous underline type is underwave.
2305 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
2307 * fileio.c (Ffile_acl): Undocument return format.
2309 2013-01-02 Glenn Morris <rgm@gnu.org>
2311 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

2323 * term.c (tty_ins_del_lines):
2324 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2325 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2327 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2329 * w32.c (unsetenv): Set up the string passed to _putenv
2331 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
2332 for the bug this caused.
2334 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
2336 * coding.c (Qmac): Now static.
2338 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2340 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
2341 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
2342 handlebox_widget. Set toolbar_in_hbox to false/true, set
2343 toolbar_is_packed to true.
2344 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
2345 (update_frame_tool_bar): Check toolbar_is_packed for packing.
2346 Show all on TOOLBAR_TOP_WIDGET.
2347 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
2348 by TOOLBAR_TOP_WIDGET.
2349 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
2350 Check toolbar_is_packed.
2351 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
2352 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2353 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
2355 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2356 (xg_update_menubar): Update title only if
2357 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2358 (xg_update_submenu): Skip tearoff only if
2359 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2360 (xg_initialize): Initialize xg_detached_menus only if
2361 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2363 * xterm.h (struct x_output): Surround handlebox_widget with
2364 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2365 toolbar_in_hbox is bool.
2367 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2369 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2370 (LIBS_GNUSTEP): Define.
2371 (LIBES): Add $(LIBS_GNUSTEP).
2372 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
2374 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2376 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2377 continuation glyph on a TTY with an indication of an empty line.
2380 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2382 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2383 file's SELinux context or ACLs successfully set, nil otherwise.
2385 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
2387 * w32proc.c (reader_thread): Avoid passing NULL handles to
2388 SetEvent and WaitForSingleObject.
2390 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2392 Port EXTERNALLY_VISIBLE to Clang 3.2.
2393 * conf_post.h (__has_attribute): New macro.
2394 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2396 2012-12-27 Glenn Morris <rgm@gnu.org>
2398 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2399 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2401 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2403 * fileio.c (file_name_as_directory, directory_file_name):
2404 Accept an additional argument MULTIBYTE to indicate whether the input C
2405 came from a multibyte or a unibyte Lisp string; all callers
2406 adjusted. Don't assume the input string is always multibyte.
2408 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2409 don't ENCODE_FILE them, and return a unibyte string if the input
2411 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2412 don't assume the input strings will always be multibyte. If the
2413 input strings are multibyte, decode strings obtained from C
2416 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2418 * lisp.h (toplevel): Add two notices to the comment about
2419 defining a new Lisp data type.
2420 * print.c (print_object): If Lisp_Save_Value object's pointer
2421 is the address of a memory area containing Lisp_Objects, try
2423 * alloc.c (valid_lisp_object_p): Adjust comment.
2425 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2427 * keyboard.c (record_asynch_buffer_change): Initialize an event
2428 only if it's really needed.
2429 * frame.h (enum output_method): Remove output_mac member since
2430 it's a leftover from the deleted code.
2431 * frame.c (Fframep): Adjust user here ...
2432 * terminal.c (Fterminal_live_p): ... and here.
2433 * coding.c (Qmac): Now here because it's only used to denote
2434 end-of-line encoding type.
2435 (syms_of_coding): DEFSYM it.
2436 * frame.h (Qmac): Remove duplicated declaration.
2438 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2440 * window.c (select_window_1): Now static, since it's used only here.
2442 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2444 * window.c (window_body_cols): Subtract display margins from the
2445 window body width on TTYs as well. See
2446 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2447 for the original report.
2449 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2451 * xdisp.c (redisplay_window): Remove inner local variable
2452 because the outer shadowed one has the same meaning.
2453 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2455 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2456 (xg_create_tool_bar): Adjust users.
2458 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2460 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2461 * buffer.c (Fget_buffer_create): Use it to set compact field of
2462 struct buffer_text to avoid accessing an uninitialized value
2463 when compact_buffer is called for the first time.
2464 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2465 (Fset_buffer_modified_p): Use buffer_window_count to check
2466 whether the buffer is displayed in some window.
2467 * xdisp.c (message_dolog): Likewise.
2469 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2471 * w32.c (acl_set_file): If setting the file security descriptor
2472 fails, and the new DACL is identical to the existing one, silently
2473 return success. This fixes problems for users backing up their
2474 own files without having the necessary privileges for setting
2475 security descriptors.
2477 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2479 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2480 after WaitForSingleObject returns normally. This expedites reader
2481 thread shutdown when delete_child triggers it.
2482 (reap_subprocess): More accurate commentary for why we call
2483 delete_child only when cp->fd is negative.
2485 * w32.c (sys_close): Do not call delete_child on a subprocess
2486 whose handle is not yet closed. Instead, set its file descriptor
2487 to a negative value, so that reap_subprocess will call
2488 delete_child on that subprocess when its SIGCHLD arrives.
2489 This avoids closing handles used for communications between sys_select
2490 and reader_thread, which doesn't give sys_select a chance to
2491 notice that the process exited and invoke the SIGCHLD handler for
2494 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2496 * nsfns.m (Fns_do_applescript): Run event loop until script has
2497 been executed (Bug#12969).
2498 (ns_run_ascript): Chech as_script for nil, set to nil after
2501 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2503 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2505 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2507 * w32term.c (w32fullscreen_hook): New function.
2508 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2510 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2512 * fileio.c (Finsert_file_contents): Doc fix.
2514 * w32proc.c (new_child, delete_child, find_child_pid): For a
2515 subprocess, consider its slot being in use as long as its process
2516 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2517 slot when a new process is started immediately after killing
2518 another one, without waiting enough time for the first process to
2519 be reaped and resources allocated for it be orderly freed.
2521 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2523 2012-12-21 Chong Yidong <cyd@gnu.org>
2525 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2527 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2529 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2531 * w32.c (get_name_and_id): Always pass NULL as the first argument
2532 of lookup_account_sid. Avoids crashes with UNC file names that
2533 refer to DFS domains, not to specific machine names. (Bug#12621)
2534 Remove now unused argument FNAME; all callers changed.
2535 (get_file_owner_and_group): Remove now unused argument FNAME; all
2538 2012-12-21 Chong Yidong <cyd@gnu.org>
2540 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2541 error for invalid chars, don't check for a nil return value.
2543 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2545 Avoid calls to CHAR_TO_BYTE if byte position is known.
2546 * editfns.c (make_buffer_string_both): Use move_gap_both.
2547 (Fbuffer_string): Use make_buffer_string_both.
2548 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2550 (buf_bytepos_to_charpos): Likewise.
2551 (charpos_to_bytepos): Remove.
2552 * fileio.c (Finsert_file_contents): Use move_gap_both.
2553 * search.c (Freplace_match): Likewise.
2554 * process.c (process_send_region): Likewise. Use convenient
2555 names for byte positions.
2556 * lisp.h (charpos_to_bytepos): Remove prototype.
2557 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2558 * insdel.c (move_gap): Likewise.
2560 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2562 * xdisp.c (redisplay_internal): Remove now-unused local.
2564 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2566 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2567 (redisplay_internal): Don't bother selecting the frame to get the
2568 proper value of frame-local variables (bug#13225).
2570 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2572 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2573 Rename 4th argument since it may be buffer or string. Adjust comment.
2574 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2576 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2578 * coding.c (Fdetect_coding_region): Do not check start and end with
2579 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2580 (code_convert_region): Likewise.
2582 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2584 * w32.c (acl_get_file, acl_set_file): Run the file name through
2585 map_w32_filename, and resolve any symlinks in the file name, like
2587 (acl_set_file): Call revert_to_self, if any privileges were
2590 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2592 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2593 ($(BLD)/w32.$(O)): Update dependencies.
2595 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2597 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2598 propagate redisplay's scrolling (if any) to the right window.
2599 (redisplay_internal): Use ensure_selected_frame.
2600 (display_mode_lines): Complete last fix.
2601 * window.c (select_window_1): New func, extracted from select_window.
2602 (select_window): Use it.
2603 * window.h (select_window_1): Declare.
2605 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2607 Emulate Posix ACL APIs on MS-Windows.
2608 * w32.c: Include sddl.h and sys/acl.h.
2609 (SDDL_REVISION_1): Define if not already defined.
2610 (g_b_init_get_security_descriptor_dacl)
2611 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
2612 (g_b_init_is_valid_security_descriptor)
2613 (g_b_init_set_file_security): New static flags.

2619 (IsValidSecurityDescriptor_Proc): New typedefs.
2620 (get_file_security, get_security_descriptor_owner)
2621 (get_security_descriptor_group): Set errno to ENOTSUP.

2624 (convert_sddl_to_sd, acl_valid, acl_to_text, acl_from_text)
2625 (acl_free, acl_get_file, acl_set_file): New functions.
2627 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
2629 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2631 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2632 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2633 for some of that bug's symptoms can now cause Emacs to abort.
2634 Remove the workaround.
2635 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2636 The bug that caused SIGCHLD to get lost has been fixed, and the
2637 workaround for it can now cause Emacs to abort.
2639 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2641 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2642 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2643 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
2645 2012-12-16 Romain Francoise <romain@orebokech.com>
2647 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2648 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2649 and copy ACL entries of file in addition to SELinux context if set.
2650 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2652 * Makefile.in (LIBACL_LIBS): New macro.
2655 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
2657 * fileio.c (internal_delete_file): Use bool for boolean.
2659 2012-12-15 Eli Zaretskii <eliz@gnu.org>
2661 Fix bug #13079 on MS-Windows with temp files not being deleted.

2664 (register_child): First argument is now pid_t.
2665 (record_infile, record_pending_deletion): New prototypes.
2667 * w32proc.c (new_child): Initialize input_file and
2668 pending_deletion members of the child.
2669 (delete_child): Delete the child's temporary input file, if any,
2670 that is pending deletion.
2671 (register_child): First argument is now pid_t.
2672 (record_infile, record_pending_deletion): New functions.
2673 (reap_subprocess): Fix a typo in DebPrint string.
2674 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2676 * fileio.c (internal_delete_file): Return an int again: non-zero
2677 if delete-file succeeds, zero otherwise.
2679 * lisp.h (internal_delete_file): Adjust prototype.
2681 * callproc.c (Fcall_process): Don't overwrite infile with result
2683 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2684 asynchronous subprocess, record the name of the input file name,
2686 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2687 delete the file, record it as pending deletion when the subprocess
2690 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2692 * editfns.c [HAVE_PWD_H]: Include grp.h.
2694 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
2696 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
2698 Fix permissions bugs with setgid directories etc. (Bug#13125)
2699 * dired.c (Ffile_attributes): Return t as the 9th attribute,
2700 to mark it as a placeholder. The old value was often wrong.
2701 The only user of this attribute has been changed to use
2702 file-ownership-preserved-p instead, with its new group arg.
2703 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
2705 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
2707 * xdisp.c (select_frame_for_redisplay, display_mode_lines):
2708 Keep selected_window and selected_frame in sync.
2710 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2712 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2713 try to get accurate owner and group information from NT file
2714 security APIs. This is to make most callers of 'stat' and
2715 'lstat', which don't need that information, much faster.
2717 * dired.c (Ffile_attributes) [WINDOWSNT]:
2718 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2719 owner and group information from 'lstat'.
2721 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2723 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2724 as that confuses set-auto-coding, so insist on the head-read
2725 returning the full 1024 bytes. Let lseek compute the tail offset;
2726 less work for us. Do not ignore I/O errors when reading the tail.
2728 * xdisp.c: Minor style fixes.
2729 (init_iterator): Hoist assignment out of if-expression.
2730 (markpos_of_region): Callers now test for sign, not for -1.
2732 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
2734 Minor redisplay optimization when the region length is zero.
2735 * xdisp.c (markpos_of_region): New function.
2736 (init_iterator): Do not highlight the region of zero length.
2737 (redisplay_window): Check whether the region is of non-zero length.
2738 (try_cursor_movement): Allow if the region length is zero.
2739 (try_window_reusing_current_matrix, try_window_id): Likewise.
2741 2012-12-13 Eli Zaretskii <eliz@gnu.org>
2743 * search.c (search_buffer): Check the inverse translations of each
2744 character in pattern when the buffer being searched is unibyte.
2747 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2749 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2750 files, fixing a regression from 24.2.
2751 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2753 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2755 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2756 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2757 Remove unnecessary S_ISLNK test, as (contra the comments) this
2758 function can't copy symlinks. Improve quality of error message
2759 when attempting to copy files that are neither regular files nor
2762 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
2764 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.
2765 * gtkutil.c (xg_set_toolkit_scroll_bar_thumb):
2766 * window.c (Frecenter):
2767 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
2768 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
2770 2012-12-12 Daniel Colascione <dancol@dancol.org>
2772 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2773 the dumped Emacs is not a sparse file, greatly improving Cygwin
2774 "make bootstrap" performance.
2776 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
2778 * inotify.c (inotify_callback): Generate an Emacs event for every

2992 * dbusbind.c (Fdbus_init_bus):
2994 * xterm.c (x_term_init):

3005 no longer needed here.
3006 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:

3008 (set_time_zone_rule): Maintain the TZ=value string separately.
3009 (syms_of_editfns): Don't initialize initial_tz;
3010 init_editfns now does it.
3011 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
3012 * lisp.h (xputenv): New decl.
3014 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

3029 Simplify get_lim_data.
3030 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3031 Remove USG and vlimit methods; no longer used these days.
3032 Add #error catchall just in case.
3034 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3035 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3036 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.

3058 This will cause a production Emacs to dump core instead of
3061 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3063 * frame.c (make_frame): Do not set window's buffer to t.
3064 * window.c (Fsplit_window_internal): Likewise. Previously it was
3065 used to indicate that the window is being set up. Now we use
3066 set_window_buffer for all new windows, so the condition in ...
3067 (Fset_window_buffer): ... is always true and can be removed.
3069 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3071 Convenient macro to check whether the buffer is hidden.
3072 * buffer.h (BUFFER_HIDDEN_P): New macro.

3085 * frame.h (x_char_width, x_char_height): Remove prototypes.

3096 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
3098 Fix a recently-introduced delete-process race condition.
3099 * callproc.c, process.h (record_kill_process):
3100 New function, containing part of the old call_process_kill.
3101 (call_process_kill): Use it.
3102 This does not change call_process_kill's behavior.
3103 * process.c (Fdelete_process): Use record_kill_process to fix a
3104 race condition that could cause Emacs to lose track of a child.
3106 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3108 Avoid code duplication between prev_frame and next_frame.
3109 * frame.c (candidate_frame): New function. Add comment.
3110 (prev_frame, next_frame): Use it. Adjust comment.
3112 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3114 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3115 fails, signal an error instead of continuing with an empty
3117 Encode expanded temp file pattern before passing it to mkstemp or
3120 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3121 Encode the file name before passing it to dostounix_filename, in
3122 case it will downcase it (under w32-downcase-file-names).
3125 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3127 Minor call-process cleanups.
3128 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3129 at the same time as other platforms, to simplify analysis.
3130 No need for fd0_volatile since we have synch_process_fd.
3131 Avoid needless emacs_close; arg is always negative.
3133 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3135 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous

3140 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3141 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer

3147 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3148 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3149 members to a bitfields.
3151 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3153 Don't let call-process be a zombie factory (Bug#12980).
3154 Fixing this bug required some cleanup of the signal-handling code.
3155 As a side effect, this change also fixes a longstanding rare race
3156 condition whereby Emacs could mistakenly kill unrelated processes,
3157 and it fixes a bug where a second C-g does not kill a recalcitrant
3158 synchronous process in GNU/Linux and similar platforms.
3159 The patch should also fix the last vestiges of Bug#9488,
3160 a bug which has mostly been fixed on the trunk by other changes.
3161 * callproc.c, process.h (synch_process_alive, synch_process_death)
3162 (synch_process_termsig, sync_process_retcode):
3163 Remove. All uses removed, to simplify analysis and so that
3164 less consing is done inside critical sections.
3165 * callproc.c (call_process_exited): Remove. All uses replaced
3166 with !synch_process_pid.
3167 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3168 These take the role of what used to be in unwind-protect arg.
3170 (block_child_signal, unblock_child_signal):
3171 New functions, to avoid races that could kill innocent-victim processes.
3172 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3173 (call_process_kill): Record killed processes as deleted, so that
3174 zombies do not clutter up the system. Do this inside a critical
3175 section, to avoid a race that would allow the clutter.
3176 (call_process_cleanup): Fix code so that the second C-g works again
3177 on common platforms such as GNU/Linux.
3178 (Fcall_process): Create the child process in a critical section,
3179 to fix a race condition. If creating an asynchronous process,
3180 record it as deleted so that zombies do not clutter up the system.
3181 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3182 light of these changes. Omit unnecessary call to emacs_close
3183 before failure, as the unwind-protect code does that.
3184 * callproc.c (call_process_cleanup):
3185 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3186 * process.c (record_deleted_pid): New function, containing
3187 code refactored out of Fdelete_process.
3188 (Fdelete_process): Use it.
3189 (process_status_retrieved): Remove. All callers changed to use
3190 child_status_change.
3191 (record_child_status_change): Remove, folding its contents into ...
3192 (handle_child_signal): ... this signal handler. Now, this
3193 function is purely a handler for SIGCHLD, and is not called after
3194 a synchronous waitpid returns; the synchronous code is moved to
3195 wait_for_termination. There is no need to worry about reaping
3196 more than one child now.
3197 * sysdep.c (get_child_status, child_status_changed): New functions.
3198 (wait_for_termination): Now takes int * status and bool
3199 interruptible arguments, too. Do not record child status change;
3200 that's now the caller's responsibility. All callers changed.
3201 Reimplement in terms of get_child_status.
3202 (wait_for_termination_1, interruptible_wait_for_termination):
3203 Remove. All callers changed to use wait_for_termination.
3204 * syswait.h: Include <stdbool.h>, for bool.
3205 (record_child_status_change, interruptible_wait_for_termination):
3207 (record_deleted_pid, child_status_changed): New decls.
3208 (wait_for_termination): Adjust to API changes noted above.
3210 * bytecode.c, lisp.h (Qbytecode): Remove.
3211 No longer needed after 2012-11-20 interactive-p changes.
3213 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3215 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3216 the scroll margin, move point outside the margin. (Bug#13055)
3218 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3220 * gtkutil.c (my_log_handler): New function.
3221 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3223 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3225 * lisp.h (modify_region): Rename to...
3226 (modify_region_1): ...new prototype.
3227 * textprop.c (modify_region): Now static. Adjust users.
3228 * insdel.c (modify_region): Rename to...
3229 (modify_region_1): ...new function to work with current buffer.
3230 Adjust comment and users. Use true and false for booleans.
3232 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3234 * alloc.c (free_save_value): New function.
3235 (safe_alloca_unwind): Use it.
3236 * lisp.h (free_save_value): New prototype.
3237 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3239 (save_excursion_restore): Adjust to match saved data structure.
3240 Use free_save_value to offload some work from GC. Drop obsolete
3243 2012-12-03 Chong Yidong <cyd@gnu.org>
3245 * fileio.c (Vauto_save_list_file_name): Doc fix.
3247 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3249 * w32fns.c: Remove prototype of atof.

3257 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3258 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3261 2012-12-03 Glenn Morris <rgm@gnu.org>
3263 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3265 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3267 Fix xpalloc confusion after memory is exhausted.
3268 * alloc.c (xpalloc): Comment fix.
3269 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3270 and signals an error, do not clear charset_table_size, as
3271 charset_table is still valid.
3272 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3274 Use execve to avoid need to munge environ (Bug#13054).
3275 * callproc.c (Fcall_process):
3276 * process.c (create_process):
3277 Don't save and restore environ; no longer needed.
3278 * callproc.c (child_setup):
3279 Use execve, not execvp, to preserve environ.
3281 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3283 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3285 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3287 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3288 display for sliced images (Bug#10500).
3290 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3292 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3294 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3295 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3297 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3299 * xdisp.c (window_outdated): Remove eassert since it hits
3300 some suspicious corner cases (see Bug#13007 and Bug#13012).
3301 (mode_line_update_needed): New function.
3302 (redisplay_internal, redisplay_window): Use it.
3303 (ensure_selected_frame): New function.
3304 (redisplay_internal, unwind_redisplay): Use it.
3305 (redisplay_internal): Move comment about buffer_shared...
3306 (buffer_shared_and_changed): ...near to its real use.
3308 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3310 * callproc.c (Fcall_process): Don't misreport vfork failure.
3312 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3314 * callproc.c (Fcall_process): Fix vfork portability problems.
3315 Do not assume that fd[0], count, filefd, and save_environ survive
3316 vfork. Fix bug whereby wrong errno value could be reported for
3317 pipe failure. Some minor cleanups, too, as follows. Move buf and
3318 bufsize to the context where they're needed. Change new_argv to
3319 be of type char **, as this is more convenient and avoids casts.
3320 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3321 Now local constants, not macros.
3323 2012-11-18 Kenichi Handa <handa@gnu.org>
3325 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3326 for the variable "f".
3328 2012-11-13 Kenichi Handa <handa@gnu.org>
3330 * font.c (font_unparse_xlfd): Exclude special characters from the
3331 generating XLFD name.
3333 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

3336 * dired.c (stat_uname, stat_gname):
3337 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
3339 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

3346 * lread.c (readbyte_from_file): Assume EINTR is defined.
3347 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3348 Assume EIO and EAGAIN are defined.
3349 * unexcoff.c (write_segment): Assume EFAULT is defined.
3351 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3353 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.

3358 violations when repeatedly clicking on the "Top" link of the
3359 "bread-crumbs" in Info buffers.

3369 were always defined.
3371 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3373 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3374 between bpos_covered and bpos_max. This fixes cursor display when
3375 several display strings follow each other.
3377 * .gdbinit (pgx): If the glyph's object is a string, display the
3378 pointer to string data, rather than the value of the string object
3379 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3381 * indent.c (Fvertical_motion): If the starting position is covered
3382 by a display string, return to one position before that, to avoid
3383 overshooting it inside move_it_to. (Bug#12930)
3385 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3387 * frame.h (struct frame): Remove display_preempted member
3388 since all users are dead long ago.

3390 * w32menu.c (pending_menu_activation): Remove since not
3392 (set_frame_menubar): Adjust user.
3393 * w32term.h (struct x_output): Drop outdated #if 0 code.
3394 (struct w32_output): Use bitfields for explicit_parent,
3395 asked_for_visible and menubar_active members.
3396 Drop unused pending_menu_activation member.
3397 * xterm.h (struct x_output): Drop outdated #if 0 code.
3398 Use bitfields for explicit_parent, asked_for_visible,
3399 has_been_visible and net_wm_state_hidden_seen members.
3401 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3403 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3404 of a literal "/". (Bug#12955)
3405 (gl-stamp): Invoke fc.exe directly, not through cmd.
3407 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
3409 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
3410 * dired.c: Assume HAVE_DIRENT_H.
3411 (NAMLEN): Remove, replacing with ...
3412 (dirent_namelen): New function. All uses changed. Use the GNU macro
3413 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3414 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3415 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3416 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3418 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3419 * ndir.h: Rename to ../nt/inc/dirent.h.
3420 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3421 Do not include <dirent.h>; no longer needed.
3422 * w32.c: Include <dirent.h> rather than "ndir.h".
3424 2012-11-23 Chong Yidong <cyd@gnu.org>
3426 * xftfont.c (xftfont_open): Remove duplicate assignment.
3428 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3430 * alloc.c (Fgarbage_collect): Unblock input after clearing
3431 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3432 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3433 * msdos.c (IT_frame_up_to_date): Use it here...
3434 * w32term.c (w32_frame_up_to_date): ...here...
3435 * xterm.c (XTframe_up_to_date): ...and here...
3436 * nsterm.m (ns_frame_up_to_date): ...but not here.
3437 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3439 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3440 Do not check whether GC is in progress.
3442 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3444 * xdisp.c (window_buffer_changed): New function.
3445 (update_menu_bar, update_tool_bar): Use it to
3446 simplify large 'if' statements.
3447 (redisplay_internal): Generalize commonly used
3448 'tail' and 'frame' local variables.
3450 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3452 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3453 with Windows system header.
3455 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3457 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3458 * alloc.c: Assume unistd.h exists.
3459 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
3460 * sysdep.c (get_current_dir_name): Assume getcwd exists.
3461 (getwd) [USG]: Remove; no longer needed.
3462 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3463 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3464 * w32.h (getcwd): Remove decl.
3466 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
3468 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
3469 Make it set selected_window as well.
3470 (update_tool_bar): Use it.
3472 2012-11-21 Ken Brown <kbrown@cornell.edu>
3474 * emacs.c (main): Set the G_SLICE environment variable for all
3475 Cygwin builds, not just GTK builds. See
3476 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3478 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3480 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3481 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3482 Define for the MSVC compiler.
3484 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3486 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3487 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3488 dostounix_filename. Prevents crashes down the road, because
3489 dostounix_filename assumes it gets a unibyte string.
3490 Reported by Michel de Ruiter <michel@sentient.nl>, see
3491 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html

3501 Test NILP rather than Qunbound.
3502 (Ffmakunbound): Set to Qnil.
3503 (Fsymbol_function): Never signal an error.
3504 (Finteractive_form): Ignore Qunbound.
3506 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3508 * eval.c (interactive_p): Remove no-longer-used decl.
3510 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3512 * xdisp.c (buffer_shared): Adjust comment.
3513 (buffer_shared_and_changed): New function.
3514 (prepare_menu_bars, redisplay_internal): Use it to
3515 decide whether all windows or frames should be updated.
3516 (window_outdated): New function.
3517 (text_outside_line_unchanged_p, redisplay_window): Use it.
3518 (redisplay_internal): Likewise. Fix indentation.
3520 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3522 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3523 (syms_of_eval): Remove corresponding defsubr.
3524 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3526 2012-11-19 Daniel Colascione <dancol@dancol.org>
3528 * w32fns.c (Fx_file_dialog):
3529 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3530 cygwin_convert_file_name*.
3532 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3533 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3535 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3537 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3539 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3541 * w32select.c: Include w32common.h before w32term.h, so that
3542 windows.h gets included before w32term.h uses some of its
3543 features, see below.
3545 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3547 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3549 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3551 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3553 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3554 (ns_select): Return at once if events are held (Bug#12834).
3556 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3558 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3559 Needed following 2012-10-20 change. (Bug#12902)
3561 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3563 * w32proc.c (waitpid): Remove unused label get_result.
3565 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3567 * makefile.w32-in (SYSWAIT_H): New macro.
3568 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3569 ($(BLD)/sysdep.$(O)): Update dependencies.
3571 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3573 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3574 * callproc.c (relocate_fd): Assume F_DUPFD.
3575 * emacs.c, term.c (O_RDWR): Remove.
3576 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3577 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3578 * nsterm.m: Assume <fcntl.h> exists.
3579 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3580 (create_pty, Fmake_network_process, server_accept_connection)
3581 (wait_reading_process_output, init_process_emacs):
3583 (wait_reading_process_output): Put in a special case for WINDOWSNT
3584 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3585 It's not clear this is needed, but it's a more-conservative change.
3586 (create_process): Assume FD_CLOEXEC.
3587 (create_process, create_pty): Assume O_NOCTTY.
3588 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3589 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3590 Omit if not DOS_NT, since F_GETFL is not defined there.
3591 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3592 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3594 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3595 lack it, since gnulib guarantees this.
3596 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3598 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3600 * w32.c (faccessat): Pretend that directories have the execute bit
3601 set. Emacs expects that, e.g., in files.el:cd-absolute.
3603 * w32proc.c (create_child): Don't clip the PID of the child
3604 process to fit into an Emacs integer, as this is no longer a
3606 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3607 reaping only the process specified by PID argument, if that is
3608 positive. Use PID instead of dead_child to know which process to
3609 reap. Wait for the child to die only if WNOHANG is not in
3611 (sys_select): Don't set dead_child.
3613 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3614 as it is no longer needed.
3616 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3618 (record_child_status_change): Remove the setting of
3619 record_at_most_one_child for the !WNOHANG case.
3621 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3623 Fix problems in ns port found by static checking.
3624 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3625 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3626 not to process group.
3627 (ns_select): Use emacs_write, not write, as that's more robust
3628 in the presence of signals.
3629 (fd_handler:): Check for read errors.
3631 2012-11-16 Glenn Morris <rgm@gnu.org>
3633 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3635 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3637 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3639 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3641 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3642 use the same value of thread handle.
3643 (start_timer_thread): If the timer thread exited (due to error),
3644 clean up by closing the two handles it used. Duplicate the caller
3645 thread's handle here, so it gets duplicated only once, when
3646 launching the timer thread. Set priority of the timer thread, not
3648 (getitimer): Don't duplicate the caller thread's handle here.
3651 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3653 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3656 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3658 Remove no-longer-used pty_max_bytes variable.
3659 * process.c (pty_max_bytes): Remove; unused.
3660 (send_process): Do not set it.
3662 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3664 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3665 Update dependencies.
3667 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3669 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3670 This follows up on the 2012-09-29 patch that removed indirection
3671 for the 'function' field. Reported by Sergey Vinokurov in
3672 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3674 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3676 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3677 different name, as the MS runtime does not have such a function,
3678 and probably never will.) All callers changed. Ignore DIRFD
3679 value if PATH is an absolute file name, to match Posix spec
3680 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3683 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3685 * xdisp.c (echo_area_display, redisplay_internal):
3686 Omit redundant check whether frame_garbaged is set.
3688 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3690 Use faccessat, not access, when checking file permissions (Bug#12632).
3691 This fixes a bug that has been present in Emacs since its creation.
3692 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3693 which must set some sort of record. (Torek's bug report was against
3694 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3695 same common flaw.) See Torek's Usenet posting
3696 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3697 Posted: Fri Apr 8 14:18:56 1983.

3709 * charset.c (init_charset):
3710 * lread.c (load_path_check, init_lread):
3711 Test whether directories are accessible, not merely whether they exist.
3712 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3713 * fileio.c (check_existing, check_executable, check_writable)
3715 Use symbolic names instead of integers for the flags, as they're
3717 (check_writable): New arg AMODE. All uses changed.
3718 Set errno on failure.
3719 (Ffile_readable_p): Use faccessat, not stat + open + close.
3720 (Ffile_writable_p): No need to call check_existing + check_writable.
3721 Just call check_writable and then look at errno. This saves a syscall.
3722 dir should never be nil; replace an unnecessary runtime check
3723 with an eassert. When checking the parent directory of a nonexistent
3724 file, check that the directory is searchable as well as writable, as
3725 we can't create files in unsearchable directories.
3726 (file_directory_p): New function, which uses 'stat' on most platforms
3727 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3728 (Ffile_directory_p, Fset_file_times): Use it.
3729 (file_accessible_directory_p): New function, which uses a single
3730 syscall for efficiency.
3731 (Ffile_accessible_directory_p): Use it.
3732 * xrdb.c (file_p): Use file_directory_p.
3733 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3734 * lread.c (openp): When opening a file, use fstat rather than
3735 stat, as that avoids a permissions race. When not opening a file,
3736 use file_directory_p rather than stat.
3737 (dir_warning): First arg is now a usage string, not a format.
3738 Use errno. All uses changed.
3739 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3740 that merely introduced a race.
3741 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3742 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3743 and similarly for the other O_* flags.
3744 * w32.c (sys_faccessat): Rename from sys_access and switch to
3745 faccessat's API. All uses changed.
3746 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3747 (magic_db): Rename from magic_file_p.
3748 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3749 char *, so that we don't have to test for file existence
3750 separately from opening the file for reading. This removes a race
3751 fixes a permission-checking problem, and simplifies the code.
3753 (file_p): Remove; no longer needed.
3755 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3757 Omit glyphs initialization at startup.

3763 * xdisp.c (clear_garbaged_frames): Likewise.
3765 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3767 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3768 passed to pint2str and pint2hrstr to be at most the size of the
3769 frame's decode_mode_spec_buffer. This avoids crashes with very
3770 large values of FIELD_WIDTH argument to decode_mode_spec.
3773 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3775 Fix a race with verify-visited-file-modtime (Bug#12863).
3776 Since at least 1991 Emacs has ignored an mtime difference of no
3777 more than one second, but my guess is that this was to work around
3778 file system bugs that were fixed long ago. Since the race is
3779 causing problems now, let's remove that code.
3780 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3781 whose time stamp is off by no more than a second. Insist that the
3782 file time stamps match exactly.
3784 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3786 * frame.h (struct frame): Convert external_tool_bar member to
3787 1-bit unsigned bitfield.
3788 * termhooks.h (struct terminal): Remove mouse_moved member since
3789 all users are long dead. Adjust comment on mouse_position_hook.
3791 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3793 Simplify by using FOR_EACH_FRAME here and there.
3794 * frame.c (next_frame, prev_frame, other_visible_frames)
3795 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3796 * w32term.c (x_window_to_scroll_bar): Likewise.
3797 * window.c (window_list): Likewise.
3798 * xdisp.c (x_consider_frame_title): Likewise.
3799 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3800 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3801 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3802 * xmenu.c (menubar_id_to_frame): Likewise.
3803 * xselect.c (frame_for_x_selection): Likewise.
3804 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3805 (x_window_to_menu_bar): Likewise.
3806 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3808 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3810 * data.c (Qdefalias_fset_function): Now static.
3812 Another tweak to vectorlike_header change.
3813 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3814 Remove, and replace all uses with ...
3815 (next_in_free_list, set_next_in_free_list):
3816 New functions, which respect C's aliasing rules better.
3818 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3820 * window.c (list4i): Rename from 'quad'. All uses changed.
3821 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3823 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3825 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3826 warning about mixing declarations and code in ISO C90.
3828 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3830 * window.c (Fsplit_window_internal): Set combination limit of
3831 new parent window to t iff Vwindow_combination_limit is t;
3832 fixing a regression introduced with the change from 2012-09-22.
3833 (Fset_window_combination_limit): Fix doc-string.
3835 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3837 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3838 amount when the scroll margins are too large. When scrolling
3839 backwards in the buffer, give up if cannot reach point or the
3840 scroll margin within a reasonable number of screen lines.
3841 Fixes point position in window under scroll-up/down-aggressively when
3842 point is positioned many lines beyond the window top/bottom.
3845 * ralloc.c (relinquish): If real_morecore fails to return memory
3846 to the system, don't crash; instead, leave the last heap
3847 unchanged and return. (Bug#12774)
3849 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3851 * lisp.h (AUTOLOADP): New macro.

3856 (Finteractive_form): Simplify.
3857 (Fquo): Don't insist on having at least 2 arguments.
3858 (Qdefalias_fset_function): New var.
3860 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3862 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
3864 * nsfont.m (Qcondensed, Qexpanded): New variables.

3866 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3868 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3870 Fix recently introduced crash on MS-Windows (Bug#12839).
3871 * w32term.h (struct scroll_bar): Use convenient header.
3872 (SCROLL_BAR_VEC_SIZE): Remove.
3873 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3875 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3877 Tweak last vectorlike_header change.
3878 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3879 vectorlike object on the free list. This is introduced to avoid
3880 some (but not all) pointer casting and aliasing problems, see
3881 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3882 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3884 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3886 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3888 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3889 been removed, so remove them here also.
3891 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3893 * doc.c (Fdocumentation): Handle new property
3894 dynamic-docstring-function to replace the old ad-advice-info.
3896 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3898 * fns.c (Qeql, hashtest_eq): Now static.
3900 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3902 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3903 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3904 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

3911 * lisp.h (sxhash_combine): New inline function, with the contents
3912 of the old SXHASH_COMBINE.

3914 special hash function containing a comparison that always yields 1.
3916 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3918 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3919 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3920 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3923 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3925 * image.c (xpm_make_color_table_h): Fix compiler error because
3926 make_hash_table changed.

3930 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3932 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3934 Use ad-hoc comparison function for the profiler's hash-tables.
3935 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3936 (make_log): Use them.
3937 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3938 call Fequal any more.

3948 (hash_lookup, hash_remove_from_table): Move assertion checking of
3949 hashfn result here. Check hash-equality before calling cmpfn.

3986 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
3987 (Fmake_bool_vector): Likewise.
3988 (struct large_vector): New type to represent allocation unit for
3989 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3990 (large_vectors): Change type to struct large_vector.
3991 (allocate_vector_from_block): Simplify.
3992 (PSEUDOVECTOR_NBYTES): Replace with...

4014 * keyboard.c (event_to_kboard): Do not dereference
4015 frame_or_window field of SELECTION_REQUEST_EVENT
4016 and SELECTION_CLEAR_EVENT events (Bug#12814).

4021 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4022 such as Scroll Lock, if the respective keys are treated as
4023 function keys, not as modifiers. This avoids destroying non-ASCII
4024 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4026 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4028 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4030 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4032 Restore some duplicate definitions (Bug#12814).
4033 This undoes part of the 2012-11-03 changes. Some people build
4034 with plain -g rather than with -g3, and they need the duplicate
4035 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4036 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4037 Define as macros, as well as as enums or as constants.

4042 to keypad keys (Bug#12816).
4044 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4046 Minor adjustments of recently-changed frame functions.
4047 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4048 known to be a frame (we're in the FRAMEP branch).
4049 * lisp.h (Qframep): Remove decl. frame.h declares this.
4050 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4051 since they're meant for Lisp fixnum values.
4053 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4055 * window.c (Fwindow_combination_limit): Revert to the only
4056 required argument and adjust docstring as suggested in
4057 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4058 by Martin Rudalics <rudalics@gmx.at>.

4111 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4112 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4113 file descriptor 2 for standard error. (Bug#12805)
4115 2012-11-05 Chong Yidong <cyd@gnu.org>
4117 * process.c (wait_reading_process_output): Revert previous change.
4119 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4121 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4122 This removes code that has been obsolete since around 1990.
4123 * callproc.c (Fcall_process):
4125 * process.c (create_process):
4126 * term.c (dissociate_if_controlling_tty):

4135 (tcgetpgrp, setpgid, setsid): New functions.
4136 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4137 * term.c (no_controlling_tty): Remove; unused.
4138 * w32proc.c (setpgrp): Remove.
4139 (setsid, tcgetpgrp): New functions.
4141 Simplify by assuming __fpending.
4142 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4143 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4144 Do not assume that __fpending's result fits in int.
4146 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4148 Remove EMACS_OUTQSIZE+sleep hack.
4149 * dispnew.c (update_frame_1): Remove hack for terminals slower
4150 than 2400 bps, which throttled Emacs by having it sleep.
4151 This code hasn't worked since at least 2007, when the multi-tty stuff
4152 was added, and anyway those old terminals are long dead.
4153 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4154 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4156 Fix data-loss with --version (Bug#9574).
4157 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4158 as we can't assume that emacs_strerror is initialized, and strerror
4159 is good enough here.
4160 (main): Invoke atexit earlier, to catch earlier instances of
4161 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4163 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4165 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4166 (keyDown): Remap keypad keys to X11 virtual key codes.
4168 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4170 Fix data-loss with --batch (Bug#9574).
4171 * emacs.c: Include <close-stream.h>.
4172 (close_output_streams): New function.
4173 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4174 and handles errors appropriately.
4175 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4178 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4179 The symptom is a diagnostic "GLib-WARNING **: In call to
4180 g_spawn_sync(), exit status of a child process was requested but
4181 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4182 waitpid(), so exit status can't be returned." The diagnostic
4183 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4184 The real bug is a race condition between Emacs and glib: Emacs
4185 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4186 so that glib can't find it. Work around the bug by invoking
4187 waitpid only on subprocesses that Emacs itself creates.
4188 * process.c (create_process, record_child_status_change):
4189 Don't use special value -1 in pid field, as the caller now must
4190 know the pid rather than having the callee infer it.
4191 The inference was sometimes incorrect anyway, due to another race.
4192 (create_process): Set new 'alive' member if child is created.
4193 (process_status_retrieved): New function.
4194 (record_child_status_change): Use it.
4195 Accept negative 1st argument, which means to wait for the
4196 processes that Emacs already knows about. Move special-case code
4197 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4198 processes that have already been waited for, by testing and
4199 clearing new 'alive' member.
4200 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4201 now does this internally.
4202 (handle_child_signal): Let record_child_status_change do all
4203 the work, since we do not want to reap all exited child processes,
4204 only the child processes that Emacs itself created.
4205 * process.h (Lisp_Process): New boolean member 'alive'.
4207 Omit duplicate definitions no longer needed with gcc -g3.
4208 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4209 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4210 Define only as macros. There's no longer any need to also define
4211 these symbols as enums or as constants, since we now assume
4212 gcc -g3 when debugging.
4214 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4216 * lisp.mk: Adjust comments to the fact that term/internal is now
4217 loaded from loadup.el.
4219 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4220 (msdos_fatal_signal): New function.
4221 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4224 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4225 for GCC versions before 4.
4226 (emacs_raise): Define to call msdos_fatal_signal.
4228 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4229 iterator when starting in the middle of a display or overlay
4232 2012-11-03 Chong Yidong <cyd@gnu.org>
4234 * process.c (wait_reading_process_output): Clean up the last
4237 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4239 * process.c (wait_reading_process_output): Avoid a race condition
4240 with SIGIO delivery (Bug#11536).
4242 2012-11-03 Chong Yidong <cyd@gnu.org>
4244 * buffer.c (cursor_type): Untabify docstring.
4246 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4248 * frame.h (struct frame): Drop can_have_scroll_bars member
4249 which is meaningless for a long time. Adjust comments.
4250 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4251 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4253 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4255 * window.c (decode_next_window_args): Update window arg after
4256 calling decode_live_window and so fix crash reported at
4257 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4258 by Juanma Barranquero <lekktu@gmail.com>.
4259 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4260 * font.c (Ffont_at): Likewise.
4262 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4264 * widget.c (resize_cb): New function.
4265 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4266 (EmacsFrameResize): Check if all is up to date before changing frame
4269 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4271 Implement backtrace output for fatal errors on MS-Windows.
4272 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4273 (BACKTRACE_LIMIT_MAX): New macro.
4274 (w32_backtrace): New function.
4275 (emacs_abort): Use w32_backtrace when the user chooses not to
4276 attach a debugger. Update the text of the abort dialog.
4278 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4280 Window-related stuff cleanup here and there.
4281 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4282 Use decode_any_window.
4283 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4284 * xdisp.c (Fformat_mode_line): Likewise.
4285 * font.c (Ffont_at): Use decode_live_window.
4286 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4287 * window.c (decode_next_window_args): Likewise.
4288 (decode_any_window): Remove static.
4289 * window.h (decode_any_window): Add prototype.
4290 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4291 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4294 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4296 Remove pad from struct input_event.
4297 * termhooks.h (struct input_event): Remove padding field.
4299 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4300 member is never cons for a long time. Adjust comment.
4301 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4302 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4303 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4304 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4306 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4308 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4310 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4312 Fix crash when using Emacs as commit editor for git (Bug#12697).
4313 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4314 and it is configured in conf_post.h.
4315 (Fcall_process): Don't invoke both setsid and setpgid; the former
4316 is enough, if it exists.
4317 * callproc.c (Fcall_process, child_setup):
4318 * process.c (create_process): Use setpgid.
4319 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4321 * dispnew.c (init_display): Initialize the foreground group
4322 if we are running a tty display.
4323 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4324 * lisp.h (init_foreground_group): New decl.
4325 * sysdep.c (inherited_pgroup): New static var.
4326 (init_foreground_group, tcsetpgrp_without_stopping)
4327 (narrow_foreground_group, widen_foreground_group): New functions.
4328 (init_sys_modes): Narrow foreground group.
4329 (reset_sys_modes): Widen foreground group.
4331 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4333 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4335 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4337 * minibuf.c (read_minibuf): Restore current buffer since
4338 choose_minibuf_frame calling Fset_frame_selected_window may
4339 change it (Bug#12766).
4341 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4343 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4345 2012-10-30 Kenichi Handa <handa@gnu.org>
4347 * font.c (Ffont_at): If WINDOW is specified and it is not
4348 displaying the current buffer, signal an error.
4350 2012-10-29 Daniel Colascione <dancol@dancol.org>
4352 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4353 In preparation for fixing bug#12739, move these functions from
4356 * coding.h, coding.c: ... to here, and compile them only when
4357 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4358 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4360 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4362 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4363 (timer_loop, getitimer, setitimer): Use it instead of
4364 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4366 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4369 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4371 * nsterm.m (NO_APPDEFINED_DATA): New define.
4372 (last_appdefined_event_data): New variable
4373 (last_appdefined_event): Remove.
4374 (ns_select): Initialize t from last_appdefined_event_data instead
4375 of [last_appdefined_event data1].
4376 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4377 remove last_appdefined_event (Bug#12698).
4379 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4381 * frame.c (x_set_font): Catch internal error.
4383 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4385 Avoid overflow in w32 implementation of interval timers.
4386 When possible, for ITIMER_PROF count only times the main thread
4388 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4389 'volatile ULONGLONG' types. All the other data which was
4390 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4391 (GetThreadTimes_Proc): New typedef.
4392 (w32_get_timer_time): New function, returns a suitable time value
4394 (timer_loop): Enter critical section when accessing ULONGLONG
4395 values of the itimer_data struct, as these accesses are no longer
4396 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4397 Remove unused variable.
4398 (init_timers): Initialize s_pfn_Get_Thread_Times.
4399 (start_timer_thread): Don't assign itimer->caller_thread here.
4400 (getitimer): Assign itimer->caller_thread here.
4401 (setitimer): Always call getitimer to get the value of ticks_now.
4402 (sys_spawnve): Avoid compiler warning about format mismatch.
4404 2012-10-26 Eli Zaretskii <eliz@gnu.org>
4406 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4407 mouse movement events if the menu bar is active. This avoids
4408 producing a busy "hour-glass" cursor by Windows if the mouse
4409 pointer is positioned over a tooltip shown for some menu item.
4411 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4413 Don't assume process IDs fit in int.
4414 * emacs.c (shut_down_emacs) [!DOS_NT]:
4415 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4416 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4417 Use pid_t, not int, to store process IDs, as 'int'
4418 is not wide enough on a few platforms (e.g., AIX and IRIX).
4420 2012-10-23 Kenichi Handa <handa@gnu.org>
4422 The following change is to make face-font-rescale-alist work
4423 correctly for non-ASCII fonts.
4425 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4426 (font_open_for_lface): Handle Vface_font_rescale_alist.
4428 2012-10-23 Chong Yidong <cyd@gnu.org>
4430 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4432 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
4434 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
4436 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
4438 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
4441 2012-10-21 Glenn Morris <rgm@gnu.org>
4443 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4445 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4447 Port to OpenBSD 5.1.
4448 * frame.c (Fmouse_position, Fmouse_pixel_position):
4449 * xdisp.c (produce_stretch_glyph):
4450 Declare local vars only when they're needed.
4451 This is clearer and avoids a warning on OpenBSD about unused vars.
4452 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
4453 This is safer, and avoids OpenBSD warnings about unused vars.
4454 * keyboard.c (record_menu_key): Remove unnecessary decl.
4455 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4456 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4457 as our definition clashes with OpenBSD's.
4458 * xfaces.c (load_face_colors, check_lface_attrs)
4459 (get_lface_attributes_no_remap, get_lface_attributes)
4460 (lface_fully_specified_p, x_supports_face_attributes_p)
4461 (tty_supports_face_attributes_p, face_fontset, realize_face)
4462 (realize_x_face, realize_tty_face):
4463 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4464 merely Lisp_Object *. This is more informative and avoids
4465 a warning on OpenBSD about accessing beyond an object's size.
4467 2012-10-20 Chong Yidong <cyd@gnu.org>
4469 * lread.c (Fload): Doc fix (Bug#12592).
4471 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
4473 * font.c (Ffont_at): Fix previous change.
4475 2012-10-19 Eli Zaretskii <eliz@gnu.org>
4477 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
4478 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
4481 * alloc.c (NSTATICS): Decrease to 0x800.
4483 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

4488 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
4490 * nsterm.m (ns_select): Check writefds before call to
4491 FD_ISSET (Bug#12668).
4493 2012-10-18 Daniel Colascione <dancol@dancol.org>
4495 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4496 (staticpro): If we run out of staticpro slots, die with an
4497 informative error instead of just calling emacs_abort.
4499 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4501 Fix two flaws reported by Dmitry Antipov.
4502 * window.c (Ftemp_output_buffer_show): Remove.
4503 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
4504 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.

4522 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
4523 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
4524 (sys_link): Add prototypes.
4526 * w32.c: Include w32select.h.
4527 (sys_access, e_malloc, sys_select): Add prototypes.
4528 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
4530 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
4532 * unexw32.c: Include lisp.h and w32.h.
4534 * term.c [WINDOWSNT]: Include w32term.h.
4536 * process.c [WINDOWSNT]: Add prototype of sys_select.
4538 * fileio.c [WINDOWSNT]: Include w32.h.
4540 * dispnew.c [WINDOWSNT]: Include w32.h.
4542 * cygw32.c (Fcygwin_convert_path_to_windows)
4543 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
4544 Lisp_Object values. (Bug#12661)
4546 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
4547 to Lisp_Object. (Bug#12661)
4549 2012-10-17 Kenichi Handa <handa@gnu.org>

4557 reset its buffer pointer to NULL (Bug#12652).
4559 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
4561 Do not verify indirection counters of killed buffers (Bug#12579).
4562 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
4563 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.
4565 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
4567 * alloc.c (Fmake_byte_code): Fix typo in comment.
4568 * print.c (print_interval): Define as static to match prototype.
4569 * indent.c (disptab_matches_widthtab, recompute_width_table):
4572 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>

4581 * dbusbind.c: Add comment explaining reason for previous change.
4583 2012-10-15 Martin Rudalics <rudalics@gmx.at>
4585 * window.c (Fwindow_end): Rewrite check whether cached position
4586 can be used (Bug#12600).
4587 (resize_frame_windows, grow_mini_window, shrink_mini_window):
4588 Set windows_or_buffers_changed.
4590 2012-10-15 Daniel Colascione <dancol@dancol.org>
4592 * dbusbind.c: Fix cygw32 build break when compiling with dbus
4593 enabled by undefining the symbol "interface", which the platform
4594 headers define to something incompatible.
4596 2012-10-14 Daniel Colascione <dancol@dancol.org>
4598 * image.c (init_tiff_functions, init_imagemagick_functions)
4599 (init_svg_functions): Fix cygw32 build break by using these
4600 functions only when WINDOWSNT _and_ HAVE_NTGUI.

4621 Fix some stat-related races.
4622 * fileio.c (Fwrite_region): Avoid race condition if a file is
4623 removed or renamed by some other process immediately after Emacs
4624 writes it but before Emacs stats it. Do not assume that stat (or
4626 * image.c (slurp_file): Resolve the file name with fopen + fstat
4627 rather than stat + fopen.
4628 (pbm_read_file) [0]: Remove unused code with stat race.
4629 * process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]:
4630 Remove ineffective code with stat race.
4632 2012-10-12 Stefan Monnier <monnier@iro.umontreal.ca>

4645 is zero (Bug#12384).
4647 2012-10-12 Juanma Barranquero <lekktu@gmail.com>
4649 * makefile.w32-in ($(BLD)/w32select.$(O)): Update dependencies.

4653 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
4655 * fileio.c (check_existing): New function.
4656 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
4657 instead of calling 'stat', when what's needed is to check whether
4658 a file exists. This avoids expensive system calls on MS-Windows.
4661 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
4663 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

4668 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
4670 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

4710 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
4712 * marker.c (cached_modiff): EMACS_INT, not int.
4714 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
4715 instead of having a wrong decl.
4716 * nsmenu.m (waiting_for_input): Remove wrong decl.
4718 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4720 keyboard.c, keymap.c: Use bool for booleans.

4752 * keyboard.c (timers_run, swallow_events)
4753 (detect_input_pending_run_timers):
4754 * process.c (wait_reading_process_output):
4755 Use unsigned for counter where wraparound-on-overflow is desired,
4756 since unsigned is guaranteed to have that behavior and signed is not.
4757 (read_char): Use ptrdiff_t for string length.
4758 (get_input_pending): Remove first argument, since it was always
4759 the same pointer-to-int (now pointer-to-boolean) &input_pending,
4760 and behave as if it had that value. Return new value of
4761 input_pending. All callers changed.
4762 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4763 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
4765 * keymap.c (push_key_description): Omit last arg, which was always 1.
4766 All callers changed.
4768 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
4770 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

4785 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
4786 Don't include termopts.h.
4788 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
4790 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
4792 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4794 * commands.h (immediate_quit): Remove duplicate decl.
4796 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
4798 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
4800 (nsfont_open): Remove setting of Vfonts_in_cache.
4801 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
4803 2012-10-09 Eli Zaretskii <eliz@gnu.org>
4805 * w32fns.c (w32_last_error): Change the return value to DWORD, to
4806 match what GetLastError returns. Explain why the function is
4809 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4810 'is_tooltip_frame', to avoid confusion with its global namesake.
4812 2012-10-08 Daniel Colascione <dancol@dancol.org>
4814 * xdisp.c (start_hourglass): Call w32_note_current_window when
4815 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4816 build that caused Emacs to display the hourglass cursor forever.
4818 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4819 which is broken under remote desktop, calculate the number of
4820 colors available for a display based on the display's number of
4821 planes and number of bits per pixel per plane. (bug#10397).
4823 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4825 * nsfont.m (Vfonts_in_cache): New variable.
4826 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4827 are used. Add cached fonts to Vfonts_in_cache.
4828 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4830 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4832 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4834 (FONT_H): Define after FRAME_H.
4835 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4836 Update dependencies.
4838 * w32term.c: Remove leftover declaration of keyboard_codepage.
4840 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4842 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4843 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4844 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4845 (GLOBAL_SOURCES): Add cygw32.c.
4846 ($(BLD)/unexw32.$(O)):
4848 ($(BLD)/w32console.$(O)):
4849 ($(BLD)/w32fns.$(O)):
4850 ($(BLD)/w32heap.$(O)):
4851 ($(BLD)/w32menu.$(O)):
4852 ($(BLD)/w32proc.$(O)): Add w32common.h.
4854 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4856 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4858 2012-10-08 Daniel Colascione <dancol@dancol.org>
4860 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4861 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4862 accidental message numbering hole. Change other messages to
4865 * w32select.h (HAVE_W32SELECT): Remove.
4867 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4868 w32common.h instead of w32heap.h.
4870 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4871 (get_allocation_unit, get_processor_type, get_w32_major_version)
4872 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4873 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4874 (OS_NT, os_subtype, cache_system_info): Move declarations to
4877 * w32heap.c: Include w32common.h.
4878 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4879 (w32_minor_version, w32_build_number, w32_subtype):
4880 Remove duplicate definitions.
4882 * w32fns.c: Include w32common.h; include w32heap.h only in
4885 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4886 Use `report_file_error' instead of `error' in order to better
4887 inform users of what went wrong. Increase NTGUI_UNICODE file
4888 dialog box file name length to 32k, the maximum allowed by the NT
4891 * w32common.h: New file.
4892 (ROUND_UP, ROUND_DOWN, get_page_size)
4893 (get_allocation_unit, get_processor_type, get_w32_major_version)
4894 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4895 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4896 (OS_NT, os_subtype, cache_system_info): Move here.
4898 * unexw32.c, unexcw.c: Include w32common.h.
4900 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4901 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4902 to call syms_of_w32select.
4904 * cygw32.h: Remove obsolete EXFUN declarations.
4906 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4908 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4909 of w32inevt.o from SOME_MACHINE_OBJECTS.
4911 2012-10-08 Daniel Colascione <dancol@dancol.org>
4913 * image.c: Permanent fix for JPEG compilation issue --- limit
4914 jpeglib `boolean' redefinition to Cygwin builds.
4916 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4918 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4920 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4923 2012-10-08 Daniel Colascione <dancol@dancol.org>
4925 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4926 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4927 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4928 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4929 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4930 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4931 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4932 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4933 now a supported configuration.
4935 * Makefile.in: consolidate image variables into LIBIMAGE; add
4936 W32_OBJ and W32_LIBS. Compile new files.
4939 (_DebPrint) declare tracing facility for W32 debugging. We need
4940 to unify tracing later.
4942 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4943 unconditional use of W32 Unicode functions. Cygwin runs only on
4944 100% Unicode operating systems.
4946 * cygw32.c: New file. Define Cygwin-specific facilities.
4947 (Fcygwin_convert_path_to_windows)
4948 (Fcygwin_convert_path_from_windows): New user functions for
4949 accessing Cygwin path-munging routines.
4951 * cygw32.h: New file.
4952 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4953 UTF-16LE strings temporarily inside non-Lisp-visible string
4956 (w32_strerror): Just what it says on the tin.
4958 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4959 also run for Cygwin; both systems have the same problem with using
4960 GUI facilities in a forked child. Also call syms_of_cygw32,
4961 syms_of_w32select in correct places.
4963 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4964 needs fork-then-exec for daemon launching.
4966 * font.h: Include frame.h.
4968 * image.c: Use the image library cache machinery only when we're
4969 compiling for native WINDOWSNT; Cygwin can use shared libraries
4970 like any other Unixlike system.
4972 * keyboard.c: Clarify a comment regarding the input loop.
4974 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4975 functions directly instead of trying to detect at runtime that our
4976 host operating system supports them. We make this change for two
4977 reasons: Cygwin lacks support for the multibyte character
4978 conversion functions used by the legacy menu code, and Cygwin
4979 never needs to rely on non-Unicode APIs.
4981 * unexw32.c (hinst): Declare extern.
4983 * w32.c: Change header order;
4984 (w32_strerror): Move to w32fns.c because we need it for
4985 non-WINDOWSNT builds.
4987 * w32.h: Add #error macro to make sure we don't include w32.h for
4988 Cygwin builds. Remove w32select declarations.
4990 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4991 w32fns.c. w32console.c is WINDOWSNT-only.
4993 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4994 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4996 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4997 (w32_major_version, w32_minor_version, w32_build_number)
4998 (os_subtype, sound_type): Define here
4999 (w32_defined_color): Make color parameter const for consistency
5000 with other _defined_color functions.
5001 (w32_createwindow): Unconditionally call w32_init_class instead of
5002 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5003 through the code is complex and unnecessary because class
5004 registration is practically free.
5005 (w32_name_of_message): New EMACSDEBUG-only function.
5006 (Fset_message_beep): Move here
5007 (Fx_open_connection): Require that the display name for Windows be
5008 "w32" for consistency, emacsclient disambiguation, and maybe, one
5009 day, multi-window-system support.
5010 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5011 Cygwin files for W32 GUI facilities, since these clearly don't
5012 expect Cygwin names.
5013 (_DebPrint): Define.
5014 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5015 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5016 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5017 (w32_last_error): Remove.
5019 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5021 * w32heap.c (syspage_mask): Declare here.
5022 (cache_system_info): Remove.
5024 * w32inevt.c (faked_key): Define globally, not statically.
5025 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5026 (w32_console_toggle_lock_key): Move to w32fns.c.
5028 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5030 * w32proc.c (_DebPrint): Move to w32fns.c.
5031 * w32select.c: Include string.h, stdio.h for Cygwin.
5032 * w32select.h: New File.
5034 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5036 (w32_message_fd): New variable. Under Cygwin, holds the file
5037 descriptor the system used to tell us about pending thread
5040 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5041 that prevented compilation under non-WINDOWSNT systems.
5043 (w32_initialize): Open /dev/windows and assign it to
5044 w32_message_fd. Provide w32 feature.
5046 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5047 (WM_EMACS_INPUT_READY): add.
5048 (prepend_msg, w32_message_fd): Declare globally.
5051 (keyboard_handle): Use only when WINDOWSNT.
5052 (notify_msg_ready): New function. Posts a message to the main
5053 thread's message queue under CYGWIN, which wakes up the main
5054 thread from select(2) by making the /dev/windows file descriptor
5055 ready. Under WINDOWSNT, it sets an event the same way the old
5058 (post, prepend_msg): Actually call notify_msg_ready instead of
5059 setting the input event directly.
5061 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5063 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5064 but it still has blocs in it, don't return it to the system,
5065 instead of aborting. (Bug#12402)
5067 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5069 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5071 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5072 MAC_OS_X_VERSION_10_6.
5073 (syms_of_nsterm): Remove comment about Panther and above for
5075 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5076 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5077 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5079 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5080 MAC_OS_X_VERSION_10_4.

5100 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5102 Improve sys_siglist detection.
5103 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5104 defined as a macro, as is done in Solaris.
5105 (sys_siglist_entries): New macro.
5106 (save_strsignal): Use it.
5107 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5108 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5110 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5112 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5113 fullscreen/Fullscreen.
5115 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5116 tobar_height is new.
5118 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5119 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5120 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5121 (windowDidResize:): Check for correct window if old style fullscreen.
5122 Capitalize word in comment. Remove incorrect comment.
5123 (initFrameFromEmacs:): tbar_height renamed tibar_height.

5133 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5135 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5137 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5139 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5140 that time stamps of directories could also be changed.
5141 Don't request the too broad GENERIC_WRITE, only the more restrictive
5142 FILE_WRITE_ATTRIBUTES access rights.
5144 * fileio.c (Fset_file_times): Special-case ignoring errors for
5145 directories only on MSDOS, not on MS-Windows.
5147 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5149 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5151 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5153 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5154 see whether CreateFile failed.
5156 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5158 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5159 to avoid similar races.
5160 * keyboard.c (pending_signals): Now bool, not int.
5162 Port timers to OpenBSD, plus check for timer failures.
5163 OpenBSD problem reported by Han Boetes.
5164 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5166 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5167 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5168 like OpenBSD, which has timer_settime but does not declare it.
5169 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5170 whether to use itimerspec-related primitives. All uses of
5171 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5173 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5175 * profiler.c (handle_profiler_signal): Fix a malloc race
5176 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5178 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5180 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5182 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5184 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5185 consistent with the change in return value of 'safe_strsignal'.
5187 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5189 Prefer plain 'static' to 'static inline' (Bug#12541).
5190 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5191 (bidi_set_sor_type, bidi_push_embedding_level)
5192 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

5197 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5198 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5199 Now 'static', not 'static inline'.
5201 Count overruns when profiling; change units to ns.
5202 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5203 Give extra weight to samples after overruns, to attempt to count
5204 the time more accurately.
5205 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5206 the underlying primitives nominally do ns.
5207 (Fprofiler_cpu_start): Document the change. Mention that
5208 the sampling intervals are only approximate.
5210 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5212 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5214 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5215 case for the special 0 coding-system.
5217 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5218 (Fmake_overlay): Remove redundant tests.
5219 (fix_start_end_in_overlays): Remove redundant recentering.
5221 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5223 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5224 Update dependencies.
5226 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5228 Fix a malloc race condition involving strsignal.
5229 A signal can arrive in the middle of a malloc, and Emacs's signal
5230 handler can invoke strsignal, which can invoke malloc, which is
5231 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5232 Fix it by altering the signal handler so that it does not invoke
5234 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5235 * process.c (status_message): Use const pointer, in case strsignal
5236 is #defined to safe_strsignal.
5237 * sysdep.c (sys_siglist, init_signals): Always define and
5238 initialize a substitute sys_siglist if the system does not define
5239 one, even if HAVE_STRSIGNAL.
5240 (safe_strsignal): Rename from strsignal. Always define,
5241 using sys_siglist. Return a const pointer.
5242 * syssignal.h (safe_strsignal): New decl.
5243 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5245 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5247 * w32proc.c (timer_loop): Fix code that waits for timer
5248 expiration, to avoid high CPU usage.
5250 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5252 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5253 (sweep_weak_table): Remove redundant prototypes.
5255 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5257 * emacs.c: Move the inclusion of TERM_HEADER after including
5258 windows.h on WINDOWSNT. This avoids compilation problems with
5261 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5263 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5264 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5265 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5266 as the previous version used 'void *'.
5268 * ralloc.c (ROUNDUP): Fix last change.
5269 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5272 * w32proc.c <disable_itimers>: New static flag.
5273 (init_timers): Initialize it to zero, after creating the critical
5274 sections used by the timer threads.
5275 (term_timers): Set to 1 before deleting the critical sections.
5276 (getitimer, setitimer): If disable_itimers is non-zero, return an
5277 error indication without doing anything. Reported by Fabrice
5278 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5279 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5281 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5284 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5285 term_ntproc after all the other bookkeeping, to get timers working
5286 as long as possible.
5288 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5290 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5291 Suggested by Juri Linkov in
5292 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5294 Prefer plain 'static' to 'static inline' (Bug#12541).
5295 With static functions, modern compilers inline pretty well by
5296 themselves; advice from programmers often hurts as much as it helps.
5297 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5298 this change shrinks the text size of the Emacs executable by 1.1%
5299 without affecting CPU significantly in my benchmark.
5300 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

5380 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
5382 Revert the FOLLOW-SYMLINKS change for file-attributes.
5383 Doing it right would require several changes to Tramp, and there's
5384 not enough time to get that tested before the freeze today.
5385 * dired.c (directory_files_internal, Ffile_attributes):
5388 * frame.c (x_report_frame_params): Port better to wider ints.
5389 Do not assume that EMACS_UINT is the same width as uprintmax_t,
5390 or that pointers can be printed in 15 decimal digits.
5391 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

5427 * vm-limit.c (lim_data): Now size_t.
5428 (check_memory_limits): Adjust prototypes of real_morecore and
5429 __morecore to receive argument of type ptrdiff_t. Use size_t for

5498 Windows-specific code to display the hourglass mouse pointer is no
5500 (w32_wnd_proc): Remove code that handled the WM_TIMER message due
5501 to hourglass timer expiration.
5502 (start_hourglass, cancel_hourglass, DEFAULT_HOURGLASS_DELAY):
5503 Remove, no longer used.
5504 (w32_note_current_window, show_hourglass, hide_hourglass):
5505 New functions, in support of hourglass cursor display similar to other
5507 (syms_of_w32fns): Don't initialize hourglass_timer.
5509 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
5511 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
5513 * w32.h (init_timers, term_timers): Add prototypes.
5515 2012-09-30 Kenichi Handa <handa@gnu.org>
5517 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
5518 to the buffer relocation which may be caused by ccl_driver.

5536 (windowDidExitFullScreen, toggleFullScreen, handleFS)
5537 (setFSValue): New functions.
5538 (EmacsFSWindow): New implementation.
5539 (canBecomeKeyWindow): New function for EmacsFSWindow.

5549 fullscreen. Set maximized_width/height. Act on next_maximized.
5551 * nsterm.h (MAC_OS_X_VERSION_10_7, MAC_OS_X_VERSION_10_8): New.
5552 (EmacsView): Add variables for fullscreen.
5553 (handleFS, setFSValue, toggleFullScreen): New in EmacsView.
5554 (EmacsFSWindow): New interface for fullscreen.
5556 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
5558 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
5560 2012-09-30 Chong Yidong <cyd@gnu.org>
5562 * fns.c (Frandom): Doc fix.
5564 2012-09-30 Martin Rudalics <rudalics@gmx.at>
5566 * window.c (Vwindow_combination_limit): New default value.
5567 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
5569 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5571 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
5572 Suggested by Eli Zaretskii in
5573 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
5575 2012-09-30 Eli Zaretskii <eliz@gnu.org>
5577 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
5578 HAVE_TIMER_SETTIME is defined.
5580 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5582 Profiler improvements: more-accurate timers, overflow checks.
5583 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
5584 signal.h, setjmp.h. Include systime.h instead.
5585 (saturated_add): New function.
5586 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
5587 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
5588 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
5590 (enum profiler_cpu_running): New enum.
5591 (profiler_cpu_running): Now of that enum type, not bool.
5592 All uses changed to store the new value.
5593 (handle_profiler_signal): Rename from sigprof_handler_1,
5594 for consistency with other handlers. Do not check whether
5595 cpu_log is a hash-table if garbage collecting, since it
5596 doesn't matter in that case.
5597 (deliver_profiler_signal): Rename from sigprof_handler,
5598 for consistency with other handlers.
5599 (setup_cpu_timer): New function, with much of what used to be in
5600 Fprofiler_cpu_start. Check for out-of-range argument.
5601 Prefer timer_settime if available, and prefer
5602 thread cputime clocks, then process cputime clocks, then
5603 monotonic clocks, to the old realtime clock. Use make_timeval
5604 to round more-correctly when falling back to setitimer.
5605 (Fprofiler_cpu_start): Use it.
5606 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5607 Don't assume that passing NULL as the 2nd argument of setitimer
5608 is the same as passing a pointer to all-zero storage.
5609 Ignore SIGPROF afterwards.
5610 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5611 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5612 non-fatal signal handlers. Ignore SIGPROF on startup.
5613 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5614 in profiler.c, since sysdep.c now uses it.
5616 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
5617 Suggested by Eli Zaretskii in
5618 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

5635 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
5636 (Frun_hook_with_args_until_failure): Doc fixes.
5638 2012-09-28 Eli Zaretskii <eliz@gnu.org>
5640 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
5641 Qautomatic_redisplay and change the symbol name. All users changed.
5643 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>
5645 * profiler.c (sigprof_handler): Fix race condition.

5668 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
5670 * character.h (MAYBE_UNIFY_CHAR): Remove.
5671 * charset.c, charset.h (maybe_unify_char): Now static.
5672 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5673 Since this stuff is now private to charset.c, there's no need for
5674 a public macro and no need to inline by hand.
5676 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>

5707 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
5709 Prefer POSIX timers if available.
5710 They avoid a race if the timer is too close to the current time.
5711 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
5712 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
5713 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
5715 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5717 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
5718 CHAR_STRING_ADVANCE.
5719 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
5720 STRING_CHAR_ADVANCE.

5738 * w32.h (Vlibrary_cache): Do not declare.
5740 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5742 * w32proc.c (sys_signal): Handle all signals defined by the
5743 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5744 handlers for signals supported by Windows. Don't override
5745 term_ntproc as the handler for SIGABRT.
5746 (sigaction): Rewrite to call sys_signal instead of duplicating its
5748 (sys_kill): Improve commentary.
5750 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5751 consistency with a signature of a signal handler. All callers
5753 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5754 install term_ntproc as a signal handler for SIGABRT, as that
5755 should be done by the dumped Emacs.
5757 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5759 * w32select.c (term_w32select): Protect against repeated
5760 invocation by setting clipboard_owner to NULL after calling
5763 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5764 and term_ntproc to their modified signatures.
5766 * character.c (char_string, string_char): Remove calls to
5767 MAYBE_UNIFY_CHAR. See the discussion starting at

5771 2012-09-25 Chong Yidong <cyd@gnu.org>
5773 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
5775 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5777 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5778 when encountering an unknown bytecode.
5780 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5782 image.c, indent.c: Use bool for booleans.
5783 * dispextern.h (struct image_type): Members valid_p, load, init
5784 now return bool, not int. All uses changed.
5785 * image.c: Omit unnecessary static decls.
5786 (x_create_bitmap_mask, x_build_heuristic_mask):
5787 Return void, not int, since callers don't care about the return value.

5822 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5824 Move pid_t related decls out of lisp.h.
5825 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5826 (interruptible_wait_for_termination):
5827 Move these decls from lisp.h to syswait.h, since they use pid_t.
5828 Needed on FreeBSD; see Herbert J. Skuhra in
5829 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5830 * callproc.c: Include syswait.h.

5850 Use bool for boolean.
5851 * gtkutil.c (xg_update_frame_menubar):

5876 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5878 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5879 fatal_error_backtrace.
5881 * w32proc.c (sys_kill): Undo last change: don't do anything when
5882 invoked to deliver SIGABRT to our own process. This is now
5883 handled by emacs_raise.
5885 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5887 * w32term.c (w32_read_socket): Remove leftover reference to
5888 interrupt_input_pending.
5890 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5892 Do not use SA_NODEFER.
5893 Problem reported by Dani Moncayo in
5894 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5896 * sysdep.c (emacs_abort): Do not reset signal handler.
5897 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5898 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5899 wanted even on POSIXish hosts, and it doesn't work on Windows.
5901 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5903 * xterm.c (x_term_init): Call fixup_locale before and after calling
5904 gtk_init (Bug#12392).
5906 2012-09-23 Chong Yidong <cyd@gnu.org>
5908 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5909 Vdynamic_library_alist.
5911 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5912 (Fgnutls_available_p): Caller changed.
5914 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5915 (Flibxml_parse_xml_region): Likewise.
5917 * dispextern.h (struct image_type): Remove arg from init function.
5919 * image.c (Finit_image_library, lookup_image_type)
5920 (define_image_type): Remove now-unneeded second arg.
5921 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5922 (init_tiff_functions, init_gif_functions, init_svg_functions):
5923 Arglist and w32_delayed_load calling convention changed.
5924 (gs_type): Remove init_gs_functions; there is no such function.
5925 (valid_image_p, make_image): Fix caller to lookup_image_type.
5927 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5929 Simplify and avoid signal-handling races (Bug#12471).
5931 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5932 Avoid recursive loop if there's a fatal error in the function itself.
5933 * atimer.c (pending_atimers):
5934 * blockinput.h: Don't include "atimer.h"; no longer needed.
5935 (interrupt_input_pending): Remove. All uses removed.
5936 pending_signals now counts both atimers and ordinary interrupts.
5937 This is less racy than having three separate pending-signal flags.
5938 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5940 Rename from their upper-case counterparts BLOCK_INPUT,
5941 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5942 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5943 This makes it easier to access volatile variables more accurately.
5944 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5945 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5946 that's more reliable if the code is buggy and sets
5947 interrupt_input_blocked to a negative value. All uses changed.
5948 * atimer.c (deliver_alarm_signal):
5949 Remove. No need to deliver this to the parent; any thread can
5950 handle this signal now. All uses replaced by underlying handler.
5951 * atimer.c (turn_on_atimers):
5952 * dispnew.c (handle_window_change_signal):
5953 * emacs.c (handle_danger_signal):
5954 * keyboard.c (kbd_buffer_get_event):
5955 Don't reestablish signal handler; not needed with sigaction.
5956 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5958 Rework to avoid unnecessary accesses to volatile variables.
5959 (UNBLOCK_INPUT_TO): Now a function.
5960 (totally_unblock_input, unblock_input): New decls.
5961 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5962 (init_data): Remove. Necessary stuff now done in init_signal.
5963 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5964 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5965 (fatal_error_code): Remove; no longer needed.
5966 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5967 it doesn't always backtrace. All uses changed. No need to reset
5968 signal to default, since sigaction and/or die does that for us now.
5969 Use emacs_raise (FOO), not kill (getpid (), FOO).
5970 (main): Check more-accurately whether we're dumping.
5971 Move fatal-error setup to sysdep.c
5972 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5973 * gtkutil.c (xg_get_file_name, xg_get_font):
5974 Remove no-longer-needed signal-mask manipulation.
5975 * keyboard.c, process.c (POLL_FOR_INPUT):
5976 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5977 * keyboard.c (read_avail_input): Remove.
5978 All uses replaced by gobble_input.
5979 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5980 (kbd_buffer_store_event_hold, gobble_input):
5981 (record_asynch_buffer_change) [USABLE_SIGIO]:
5982 (store_user_signal_events):
5983 No need to mess with signal mask.
5984 (gobble_input): If blocking input and there are terminals, simply
5985 set pending_signals to 1 and return. All hooks changed to not
5986 worry about whether input is blocked.
5987 (process_pending_signals): Clear pending_signals before processing
5988 them, in case a signal comes in while we're processing.
5989 By convention callers now test pending_signals before calling us.
5990 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5991 New functions, to support changes to blockinput.h.
5992 (handle_input_available_signal): Now extern.
5993 (reinvoke_input_signal): Remove. All uses replaced by
5995 (quit_count): Now volatile, since a signal handler uses it.
5996 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5997 All callers changed. Block SIGINT only if not already blocked.
5998 Clear sigmask reliably, even if Fsignal returns, which it can.
5999 Omit unnecessary accesses to volatile var.
6000 (quit_throw_to_read_char): No need to restore sigmask.
6001 * keyboard.c (gobble_input, handle_user_signal):
6002 * process.c (wait_reading_process_output):
6003 Call signal-handling code rather than killing ourselves.
6004 * lisp.h: Include <float.h>, for...
6005 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6006 (pending_signals): Now volatile.
6007 (syms_of_data): Now const if IEEE floating point.
6008 (handle_input_available_signal) [USABLE_SIGIO]:
6009 (terminate_due_to_signal, record_child_status_change): New decls.
6010 * process.c (create_process): Avoid disaster if memory is exhausted
6011 while we're processing a vfork, by tightening the critical section
6013 (send_process_frame, process_sent_to, handle_pipe_signal)
6014 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6016 (send_process): No need for setjmp/longjmp any more, since the
6017 SIGPIPE stuff is now gone. Instead, report an error if errno
6019 (record_child_status_change): Now extern. PID and W are now args.
6020 Return void, not bool. All callers changed.
6021 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6022 Remove. All uses removed. This bug should be fixed now in a
6024 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6025 and record the child status change directly. This avoids the
6026 need to futz with the signal mask.
6027 (process_fatal_action): Move here from emacs.c.
6028 (emacs_sigaction_flags): New function, containing
6029 much of what used to be in emacs_sigaction_init.
6030 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6031 caught by emacs, to make races less likely.
6032 (deliver_process_signal): Rename from handle_on_main_thread.
6034 (BACKTRACE_LIMIT_MAX): Now at top level.
6035 (thread_backtrace_buffer, threadback_backtrace_pointers):
6037 (deliver_thread_signal, deliver_fatal_thread_signal):
6038 New functions, for more-accurate delivery of thread-specific signals.
6039 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6040 (deliver_arith_signal): Handle in this thread, not
6041 in the main thread, since it's triggered by this thread.
6042 (maybe_fatal_sig): New function.
6043 (init_signals): New arg DUMPING so that we can be more accurate
6044 about whether we're dumping. Caller changed.
6045 Treat thread-specific signals differently from process-general signals.
6046 Block all signals while handling fatal error; that's safer.
6047 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6049 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6050 Ignore SIGPIPE unless batch.
6051 (emacs_backtrace): Output backtrace for the appropriate thread,
6052 which is not necessarily the main thread.
6053 * syssignal.h: Include <stdbool.h>.
6054 (emacs_raise): New macro.
6055 * xterm.c (x_connection_signal): Remove; no longer needed
6056 now that we use sigaction.
6057 (x_connection_closed): No need to mess with sigmask now.
6058 (x_initialize): No need to reset SIGPIPE handler here, since
6059 init_signals does this for us now.
6061 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6063 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6064 background rect may be larger (Bug#12245).
6066 2012-09-23 Chong Yidong <cyd@gnu.org>
6068 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6070 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6072 * .gdbinit: Just stop at fatal_error_backtrace.
6073 See Stefan Monnier's request in
6074 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6075 Remove no-longer-used query of system type.
6077 2012-09-22 Chong Yidong <cyd@gnu.org>
6079 * search.c (Freplace_match): Doc fix (Bug#12325).
6081 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6083 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6084 (Fline_end_position): Doc fix.
6086 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6088 2012-09-22 Chong Yidong <cyd@gnu.org>
6090 * dispextern.h (struct image_type): Add new slot, storing a type
6091 initialization function.
6093 * image.c (define_image_type): Call the image initializer function
6094 if it is defined. Arguments and return value changed.
6095 (valid_image_p, make_image): Callers changed.
6096 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6097 (gif_type, imagemagick_type, svg_type, gs_type):
6098 Add initialization functions.
6099 (Finit_image_library): Call lookup_image_type.
6100 (CHECK_LIB_AVAILABLE): Macro deleted.
6101 (lookup_image_type): Call define_image_type here, rather than via
6102 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6103 (syms_of_image): Move define_image_type calls for xbm_type and
6104 pbm_type to lookup_image_type.
6106 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6108 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6109 'idle_timers' from here ...
6110 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6111 lists, to avoid infloops when the timer does something stupid,
6112 like reinvoke itself with the same or smaller time-out.
6115 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6117 * window.c (Fsplit_window_internal): Handle only Qt value of
6118 Vwindow_combination_limit separately.
6119 (Qtemp_buffer_resize): New symbol.
6120 (Vwindow_combination_limit): New default value.
6123 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6125 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6126 the new overlay string. (Bug#10159)
6128 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6130 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6131 or that fprintf is async-signal-safe. POSIX doesn't require
6134 2012-09-22 Chong Yidong <cyd@gnu.org>
6136 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6139 2012-09-22 Kenichi Handa <handa@gnu.org>
6141 * composite.c (composition_reseat_it): Handle the case that a
6142 grapheme cluster is not covered by a single font (Bug#12352).
6144 2012-09-21 Chong Yidong <cyd@gnu.org>
6146 * image.c (define_image_type): Avoid adding duplicate types to
6147 image_types (Bug#12463). Suggested by Jörg Walter.
6149 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6151 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6152 (print_load_command_name): Add case LC_DATA_IN_CODE.
6153 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6155 2012-09-21 Glenn Morris <rgm@gnu.org>
6157 * eval.c (Frun_hook_with_args_until_success)
6158 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6160 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6162 * fileio.c (Ffile_selinux_context): Only call freecon when
6163 lgetfilecon succeeded.
6164 (Fset_file_selinux_context): Likewise. (Bug#12444)
6166 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6168 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6169 reordering, locate the cursor by calling set_cursor_from_row; if
6170 that fails, clear the desired glyph matrix before returning a
6171 failure indication to the caller. Fixes leaving garbled display
6172 when fast scrolling with a down-key. (Bug#12403)
6173 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6174 scrolling through multibyte text.
6176 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6178 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6179 calling mark_vectorlike since that's the one that marks the window.
6180 (mark_discard_killed_buffers): Mark the final cdr.
6181 * window.h (struct window): Move prev/next_buffers to the
6182 non-standard fields.
6183 * window.c (make_window): Initialize prev/next_buffers manually.
6185 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6187 Omit unused arg EXPECTED from socket hooks.
6188 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6189 * nsterm.m (ns_term_init):
6190 * termhooks.h (struct terminal.read_socket_hook):
6191 * w32inevt.c (w32_console_read_socket):
6192 * w32term.c (w32_read_socket):
6193 * xterm.c (XTread_socket):
6194 Omit unused arg EXPECTED. All callers changed.
6195 (store_user_signal_events): Return void, not int, since callers no
6196 longer care about the return value. All uses changed.
6198 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6200 * w32gui.h (XParseGeometry): Do not declare.
6202 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6204 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6205 Ignore 'expected'. See Eli Zaretskii in
6206 <http://bugs.gnu.org/12471#8> (last line).
6208 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6209 (XParseGeometry): Now static. Substitute extremal values for
6210 values that are out of range.
6212 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6214 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6216 * nsfns.m (XParseGeometry): Remove.
6217 (Fx_create_frame): Call x_set_offset to correctly interpret
6218 top_pos in geometry.
6220 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6221 (Fx_parse_geometry): If there is a space in string, call
6222 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6224 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6226 * search.c (scan_buffer): Use character positions in calls to
6227 region_cache_forward and region_cache_backward, not byte
6228 positions. (Bug#12196)
6230 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6231 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6233 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6234 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6235 emacs_blocked_malloc, now deleted.
6237 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6239 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6240 The workaround was for improving performance on Solaris 2.4, but
6241 is getting in the way now. Emacs will still work if someone is
6242 still running Solaris 2.4 in a museum somewhere; Sun dropped
6243 support for Solaris 2.4 in 2003.
6244 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6245 * process.c (create_process) [HAVE_WORKING_VFORK]:
6246 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6247 since Emacs no longer uses vfork on that platform.
6249 2012-09-17 Glenn Morris <rgm@gnu.org>
6251 * emacs.c: Use COPYRIGHT.
6253 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6255 Remove configure's --without-sync-input option (Bug#12450).
6256 When auditing signal-handling in preparation for cleaning it up,
6257 I found that SYNC_INPUT has race conditions and would be a real
6258 pain to fix. Since it's an undocumented and deprecated
6259 configure-time option, now seems like a good time to remove it.
6260 Also see <http://bugs.gnu.org/11080#16>.
6261 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6262 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6263 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6264 (malloc_hysteresis):
6265 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6266 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6267 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6268 (dont_register_blocks, bytes_used_when_reconsidered)
6269 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6270 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6271 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6272 Remove. All uses removed.
6273 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6274 implementation, one that depends on whether the new macro
6275 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6277 * atimer.c (run_timers, handle_alarm_signal):
6278 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6279 (handle_async_input, process_pending_signals)
6280 (handle_input_available_signal, init_keyboard):
6281 * nsterm.m (ns_read_socket):
6282 * process.c (wait_reading_process_output):
6283 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6284 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6286 * xterm.c (XTread_socket):
6288 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6289 * eval.c (handling_signal): Remove. All uses removed.
6290 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6291 All uses replaced with the SYNC_INPUT version.
6292 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6294 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6297 * font.c (Ffont_shape_gstring): Remove unused local.
6299 2012-09-16 Glenn Morris <rgm@gnu.org>
6301 * Makefile.in (clean): No longer run nextstep's clean.
6303 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6305 (ns-app): Move here from ns.mk, and simplify.
6306 (clean): Simplify nextstep entry.
6307 * ns.mk: Remove file.
6309 2012-09-17 Kenichi Handa <handa@gnu.org>
6311 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6312 not covert the last few charactes.
6314 2012-09-16 Kenichi Handa <handa@gnu.org>
6316 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6317 here, but just check the validity of glyphs in the glyph-string.
6319 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6321 * window.c (Fwindow_parameter, Fset_window_parameter):
6322 Accept any window as argument (Bug#12452).
6324 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6326 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6327 to ns_term_init to avoid memory leak.
6329 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6330 explicit retain/release.
6331 (ns_term_init): Only allow one display. Initialize outerpool and
6334 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6336 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6337 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6338 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6339 the Microsoft problem in a different way, by altering ../nt/config.nt.
6341 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6356 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6357 by lisp.h. This completes removal of setjmp.h inclusion
6358 erroneously announced in the previous commit. (Bug#12446)
6360 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6363 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6364 not defined as a macro. The latter happens on MS-Windows.
6367 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6369 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6370 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6371 Some instances of '#include <setjmp.h>' removed, if the
6372 only reason for the instance was because "lisp.h" was included.
6373 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6374 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6375 and _longjmp with the new symbols. Emacs already uses _setjmp if
6376 available, so this change affects only POSIXish hosts that have
6377 sigsetjmp but not _setjmp, such as some versions of Solaris and
6378 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6379 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6380 (png_load_body) [HAVE_PNG]:
6381 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6382 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6383 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6384 since PNG requires jmp_buf. This is the only exception to the
6385 general rule that we now use sys_setjmp and sys_longjmp.
6386 This exception is OK since this code does not change the signal
6387 mask or longjmp out of a signal handler.
6389 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6391 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6392 Include "syssignal.h", for 'main_thread'.
6394 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6396 Avoid out-of-range marker position (Bug#12426).
6397 * insdel.c (replace_range, replace_range_2):
6398 Adjust markers before overlays, as suggested by comments.
6399 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6400 Remove redundant check before calling offset_intervals.
6402 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6404 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6405 current buffer (Bug#12387).
6407 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6409 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6411 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6413 Use a more backwards-compatible timer format (Bug#12430).
6414 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6415 vector element, not from the 4th, since PSECS is now at the end.
6416 (Fcurrent_idle_time): Doc fix.
6418 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6420 Function to mark objects and remove killed buffers at once.
6421 * alloc.c (discard_killed_buffers): Rename to ...
6422 (mark_discard_killed buffers) ... new name. Add marking
6423 of remaining objects. Fix comment. Adjust users.
6424 (mark_object): Do not touch frame buffer lists here.
6425 * frame.c (delete_frame): Reset frame buffer lists here.
6427 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6429 Better workaround for GNOME bug when --enable-gcc-warnings.
6430 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6431 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6432 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6434 Simplify SIGIO usage (Bug#12408).
6435 The code that dealt with SIGIO was crufty and confusing, e.g., it
6436 played tricks like "#undef SIGIO" but these tricks were not used
6437 consistently. Simplify mostly by not #undeffing standard symbols,
6438 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6439 or not as we please) rather than "defined SIGIO" (standard symbol
6440 that we probably shouldn't #undef).
6441 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6442 Modules that need it can include it.
6443 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6444 * dispextern.h (ignore_sigio): New decl.
6445 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6446 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6447 * emacs.c (shut_down_emacs):
6448 * keyboard.c (kbd_buffer_store_event_hold):
6449 Use ignore_sigio rather than invoking 'signal' directly.
6450 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6452 (FIONREAD, SIGIO): Do not #undef.
6453 (tty_read_avail_input): Use #error rather than a syntax error.
6454 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6455 for I_PIPE, used by SETUP_SLAVE_PTY.
6456 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6457 * sysdep.c (croak): Remove; no longer needed. This bit of
6458 temporary code, with Fred N. Fish's comment that it's temporary,
6459 has been in Emacs since at least 1992!
6460 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6461 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6462 * syssignal.h (croak): Remove decl.
6463 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6464 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6465 now that we're termios-only.
6466 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6467 * term.c (dissociate_if_controlling_tty): Use #error rather than
6470 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6471 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6472 to work around GNOME bug 683906.
6473 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6474 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6475 This works around GCC bug 54561.
6477 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6479 More fixes for 'volatile' and setjmp/longjmp.
6480 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6481 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6482 (png_load_body) [HAVE_PNG]:
6483 (jpeg_load_body) [HAVE_JPEG]:
6484 New function, with most of the old parent function's body.
6485 (png_load) [HAVE_PNG]:
6486 (jpeg_load) [HAVE_JPEG]:
6487 Invoke the new function, to avoid longjmp munging our locals.
6488 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6489 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6490 longjmp is passed 2, as the C standard doesn't guarantee this.
6491 Instead, store the failure code into mgr->failure_code.
6493 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6495 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6496 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6497 (syms_of_keyboard): Remove support for unread-command-char.
6499 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6501 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6502 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6503 violation. (Bug#12426)
6505 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6507 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6509 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6511 * eval.c: Add `inhibit-debugger'.
6512 (Qinhibit_debugger): New symbol.
6513 (call_debugger): Bind it instead of Qdebug_on_error.
6514 (maybe_call_debugger): Test Vinhibit_debugger.
6515 (syms_of_eval): Define inhibit-debugger.
6516 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6517 (syms_of_xdisp): Remove inhibit-debug-on-message.
6519 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6521 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6522 If a nonvolatile local variable is written before a _longjmp to
6523 the frame containing the variable, and is read after the _longjmp,
6524 the value read is indeterminate. Some local variables of type
6525 'struct handler' and 'struct catchtag' are used in this way, so
6526 mark each of their slots as volatile if the slot can be set before
6527 _longjmp and read afterwards.
6528 * lisp.h (struct handler): var and chosen_clause are now volatile.
6529 (struct catchtag): val, next, and pdlcount are now volatile.
6531 * bidi.c (bidi_push_it, bidi_pop_it):
6532 * fns.c (copy_hash_table):
6533 * image.c (define_image_type):
6534 * keyboard.c (kbd_buffer_store_event_hold):
6535 * process.c (Fprocess_send_eof):
6536 * xfaces.c (x_create_gc) [HAVE_NS]:
6537 * xgselect.c (xg_select):
6538 Prefer assignment to memcpy when either will do.
6540 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6541 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6542 time an item is removed. No need to mark this function 'inline';
6543 the compiler knows better than we do.
6545 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6547 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6548 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6549 to change_frame_size (Bug#12388).
6550 (windowDidResize:): Pass YES to updateFrameSize.
6552 * nsterm.h: Add delay parameter to updateFrameSize.
6554 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6556 Discard killed buffers from deleted window and frame objects.
6557 This reduces an amount of references to killed buffers and
6558 helps GC to reclaim them faster.
6559 * alloc.c (discard_killed_buffers): New function.
6560 (mark_object): Use it for deleted windows and frames.
6561 (mark_object): If symbol's value is set up for a killed buffer
6562 or deleted frame, restore its global binding.
6563 * data.c (swap_in_global_binding): Add GC notice.
6564 (swap_in_symval_forwarding): Use convenient set_blv_where.
6565 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6566 * window.h: ... to here.
6568 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6570 Convenient macro to check whether the buffer is live.
6571 * buffer.h (BUFFER_LIVE_P): New macro.
6572 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6573 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6575 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6577 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6578 composition cases (Bug#12364).
6580 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6581 overhang of succeeding glyphs overlapping box cursor.
6583 * w32term.c (x_draw_glyph_string): Likewise.
6585 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6587 Simplify, document, and port floating-point (Bug#12381).
6588 The porting part of this patch fixes bugs on non-IEEE platforms
6589 with frexp, ldexp, logb.
6590 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6592 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6593 support, by removing commented-out code and briefly listing the
6594 C89 functions excluded. The commented-out stuff was confusing
6595 maintenance, e.g., we thought we needed cbrt but it was commented out.
6596 (logb): Remove decl; no longer needed.
6597 (isfinite): New macro, if not already supplied.
6598 (isnan): Don't replace any existing macro.
6599 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6600 are present on all C89 platforms.
6601 (Ffrexp): Do not special-case zero, as frexp does the right thing
6603 (Flogb): Do not use logb, as it doesn't have the desired meaning
6604 on hosts that use non-base-2 floating point. Instead, stick with
6605 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6606 frexp, to avoid getting an unspecified result.
6608 * xdisp.c (Qinhibit_debug_on_message): Now static.
6610 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6612 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6613 NSBezierPath (Bug#12131).
6615 2012-09-10 Chong Yidong <cyd@gnu.org>
6617 * fns.c (Fdelq, Fdelete): Doc fix.
6619 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6621 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6622 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6624 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6626 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6627 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6630 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6632 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6633 left fringe if the window has a left margin. This avoids leaving
6634 traces of the cursor because its leftmost pixel is not drawn over.
6636 * dispnew.c (update_window_line): When the left margin area of a
6637 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6638 that screen line. (Bug#12277)
6640 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6642 Assume C89 or later for math functions (Bug#12381).
6643 This simplifies the code, and makes it a bit smaller and faster,
6644 and (most important) makes it easier to clean up signal handling
6645 since we can stop worring about floating-point exceptions in
6646 library code. That was a problem before C89, but the problem
6647 went away many years ago on all practical Emacs targets.
6648 * data.c, image.c, lread.c, print.c:
6649 Don't include <math.h>; no longer needed.
6650 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6651 might be autoconfigured, as that never happens.
6653 * doprnt.c (DBL_MAX_10_EXP):
6654 * print.c (DBL_DIG):
6655 Remove. C89 or later always defines these.
6656 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6657 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6658 (arith_error, domain_error, domain_error2):
6659 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6660 no longer needed -- we simply return what C returns. All uses removed.
6661 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6663 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6664 Remove. All uses expanded, as these macros are no longer used
6665 more than once and are now more trouble than they're worth.
6666 (Ftan): Use tan, not sin / cos.
6667 (Flogb): Assume C89 frexp.
6668 (fmod_float): Assume C89 fmod.
6669 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6670 (init_floatfns): Remove. All uses removed.
6672 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6674 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6675 compositeToPoint for OSX < 10.6 (Bug#12390).
6677 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6679 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6680 This produces more-accurate results.
6682 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6684 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6685 changes (Bug#12088).
6687 2012-09-08 Chong Yidong <cyd@gnu.org>
6689 * syntax.c (Fstring_to_syntax): Doc fix.
6691 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6693 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6694 in the internal border.
6695 (x_set_window_size): Remove static variables and their usage.
6696 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6697 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6698 Remove fringe/internal border adjustment (Bug#11052).
6699 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6700 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6701 (ns_fix_rect_ibw): Remove.
6702 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6703 (ns_dumpglyphs_box_or_relief): Ditto.
6704 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6706 (ns_dumpglyphs_image): Ditto.
6707 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6709 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6710 their usage. Add fringe_extended_p and its use as in other terms.
6711 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6712 scroll bar was removed.
6713 (updateFrameSize): New function.
6714 (windowDidResize): Move code to updateFrameSize and call it.
6716 * nsterm.h (EmacsView): Add updateFrameSize.
6718 2012-09-07 Chong Yidong <cyd@gnu.org>
6720 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6722 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6724 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6726 More signal-handler cleanup (Bug#12327).
6727 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6728 Problem introduced when merging patches. Noted by Eli Zaretskii in
6729 <http://bugs.gnu.org/12327#67>.
6730 * floatfns.c: Comment fix.
6731 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6732 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6733 and anyway the declaration is harmless even if SIGDANGER is not defined.
6734 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6735 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6736 source files not surprisingly expected syssignal.h to define, or
6737 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6738 Include <sys/ioctl.h>, for FIONREAD.
6739 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6740 This eliminates a problem whereby other files mysteriously had
6741 to include "syssignal.h" before including "systty.h" if they
6742 wanted to use "#ifdef SIGIO".
6744 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6746 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6748 * w32.c (sigemptyset): Empty the set.
6749 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6751 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6753 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6755 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6756 (mark_object): Likewise for frame objects.
6758 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6760 * syssignal.h (handle_on_main_thread): Always declare,
6761 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6762 This ports to platforms without HAVE_PTHREAD.
6764 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6766 Signal-handler cleanup (Bug#12327).
6767 Emacs's signal handlers were written in the old 4.2BSD style with
6768 sigblock and sigmask and so forth, and this led to some
6769 inefficiencies and confusion. Rewrite these to use
6770 pthread_sigmask etc. without copying signal sets around. Also,
6771 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6772 'signal', and instead use functions that do not attempt to take
6773 over the system name space. This patch causes Emacs's text
6774 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6775 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6776 Do not include <signal.h> or "syssignal.h", as these
6777 modules do not use signals.
6778 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6779 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6780 Do not include <signal.h>, as "syssignal.h" does that for us now.
6781 * atimer.c (sigmask_atimers): New function.
6782 (block_atimers, unblock_atimers): New functions,
6783 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6785 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6786 no longer needed here.
6787 * emacs.c (main): Inspect existing signal handler with sigaction,
6788 so that there's no need to block and unblock SIGHUP.
6789 * sysdep.c (struct save_signal): New member 'action', replacing
6790 old member 'handler'.
6791 (save_signal_handlers, restore_signal_handlers):
6792 Use sigaction instead of 'signal' to save and restore.
6793 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6794 New function. All users of 'signal' modified to use set_sighandler
6795 if they're writeonly, and to use sys_signal if they're read+write.
6796 (emacs_sigaction_init, forwarded_signal): New functions.
6797 (sys_signal): Remove. All uses replaced by calls to sigaction
6798 and emacs_sigaction_init, or by direct calls to 'signal'.
6799 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6800 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6801 all uses replaced by pthread_sigmask etc. calls.
6802 * syssignal.h: Include <signal.h>.
6803 (emacs_sigaction_init, forwarded_signal): New decls.
6804 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6805 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6806 (sigmask, sys_sigmask): Remove; no longer needed.
6807 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6808 (sigblock, sigunblock, sigfree):
6809 (sigsetmask) [!defined sigsetmask]:
6810 Remove. All uses replaced by pthread_sigmask.
6811 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6812 no longer need to be replaced, and its typical old uses
6813 are now done via emacs_sigaction_init and sigaction.
6814 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6815 (sys_sigdel): Remove; unused.
6816 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6818 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6820 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6821 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6823 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6825 Explicitly mark buffer_defaults and buffer_local_symbols.
6826 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6827 mark_local_symbols here.
6828 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6829 since special buffers aren't marked here any more.
6830 (allocate_buffer): Chain new buffer with all_buffers here...
6831 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6833 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6834 (syms_of_buffer): Remove staticpro of the above.
6835 (init_buffer_once): Set names for buffer_defaults and
6836 buffer_local_symbols.
6838 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6840 Use bool for booleans in font-related modules.
6841 * font.c (font_intern_prop, font_style_to_value)
6842 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6843 (generate_otf_features, font_check_otf_features, font_check_otf)
6844 (font_match_p, font_list_entities, font_at):
6845 * fontset.c (fontset_id_valid_p, reorder_font_vector
6846 (fontset_find_font, Fset_fontset_font)
6847 (face_suitable_for_char_p) [0]:
6848 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6849 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6850 (m17n_flt_initialized, ftfont_shape_by_flt):
6851 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6852 * nsfont.m (nsfont_draw):
6853 * w32font.c (w32font_draw):
6854 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6855 Use bool for booleans.
6856 * font.h: Adjust to above API changes.
6857 (struct font, struct font_driver, struct font_driver_list):
6858 Use bool for booleans.
6859 (struct font): Remove useless member encoding_type.
6861 * fontset.c, xftfont.c: Omit unnecessary static decls.
6863 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6865 * alloc.c (mark_object): Revert window marking code
6866 since it's unsafe for the Fset_window_configuration.
6868 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6870 Fix race conditions with signal handlers and errno (Bug#12327).
6871 Be more systematic about preserving errno whenever a signal
6872 handler returns, even if it's not in the main thread. Do this by
6873 renaming signal handlers to distinguish between signal delivery
6874 and signal handling. All uses changed.
6875 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6876 * data.c (deliver_arith_signal): Rename from arith_error.
6877 * dispnew.c (deliver_window_change_signal): Rename from
6878 window_change_signal.
6879 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6880 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6881 * keyboard.c (deliver_input_available_signal): Rename from
6882 input_available_signal.
6883 (deliver_user_signal): Rename from handle_user_signal.
6884 (deliver_interrupt_signal): Rename from interrupt_signal.
6885 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6886 (deliver_child_signal): Rename from sigchld_handler.
6887 * atimer.c (handle_alarm_signal):
6888 * data.c (handle_arith_signal):
6889 * dispnew.c (handle_window_change_signal):
6890 * emacs.c (handle_fatal_signal, handle_danger_signal):
6891 * keyboard.c (handle_input_available_signal):
6892 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6893 * process.c (handle_pipe_signal, handle_child_signal):
6894 New functions, with the actual signal-handling code taken from the
6895 original respective signal handlers, sans the sporadic attempts to
6896 preserve errno, since that's now done by handle_on_main_thread.
6897 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6898 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6899 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6901 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6902 Move initialization of main_thread to sysdep.c's init_signals.
6903 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6904 our usage, and simplifies the mainline code.
6905 (record_child_status_change): New static function, as a helper
6906 for handle_child_signal, and with most of the old child handler's
6908 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6909 (handle_child_signal): Use the above.
6910 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6911 Moved here from emacs.c.
6912 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6913 code moved here from emacs.c's main function.
6914 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6915 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6916 This lets callers save and restore errno properly.
6918 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6920 Remove redundant or unused things here and there.
6921 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6922 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6923 * editfns.c (Fcompare_buffer_substrings): Likewise.
6924 * frame.h (struct terminal, struct font_driver_list):
6925 Remove redundant declarations.
6926 * window.h (Qleft, Qright): Likewise.
6928 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6930 Do not mark objects from deleted buffers, windows and frames.
6931 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6932 (mark_object): Likewise for windows and frames.
6934 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6936 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6937 buffer_defaults and buffer_local_symbols as valid objects.
6938 Return special value to denote them.
6940 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6942 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6943 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6944 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6945 (file_name_absolute_p, Fsubstitute_in_file_name):
6946 (check_executable, check_writable, Ffile_accessible_directory_p)
6947 (Fset_file_selinux_context, Fdefault_file_modes)
6948 (Finsert_file_contents, choose_write_coding_system)
6949 (Fwrite_region, build_annotations, a_write, e_write)
6951 * filelock.c (boot_time_initialized, get_boot_time)
6952 (get_boot_time_1, lock_file_1, within_one_second):
6953 * floatfns.c (in_float):
6954 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6955 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6956 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6957 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6958 * window.c (compare_window_configurations):
6959 Use bool for booleans.
6960 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6961 (Fdefault_file_modes): Now mode_t, not int, for modes.
6962 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6963 (internal_delete_file): Now returns void, not a (boolean) int,
6964 since nobody was looking at the return value.
6965 * lisp.h, window.h: Adjust to above API changes.
6967 * xdisp.c (set_message): Simplify and reindent last change.
6969 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6971 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6973 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6975 * eval.c (call_debugger): Make the function non-static so that we
6976 can call it from set_message.
6978 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6979 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6981 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6983 Give more-useful info on a fatal error (Bug#12328).
6984 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6985 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6986 of doing the work ourselves.
6987 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6988 do most of the work.
6989 (fatal_error_backtrace): New function, taken from the guts
6990 of the old fatal_error_signal, but with a new option to output
6992 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6993 info about the signal than just its number.
6994 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6995 * sysdep.c: Include <execinfo.h>
6996 (emacs_backtrace): New function, taken partly from the previous
6997 code of the 'die' function.
6998 (emacs_abort): Call fatal_error_backtrace rather than abort.
7000 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7002 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7003 eager (load-time) macro-expansion.
7004 * lisp.mk (lisp): Add macroexp.
7006 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7008 Simplify redefinition of 'abort' (Bug#12316).
7009 Do not try to redefine the 'abort' function. Instead, redo
7010 the code so that it calls 'emacs_abort' rather than 'abort'.
7011 This removes the need for the NO_ABORT configure-time macro
7012 and makes it easier to change the abort code to do a backtrace.
7013 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7014 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7015 Remove; sysdep.c's emacs_abort now takes its place.
7016 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7017 'abort' changed to use 'emacs_abort'.
7018 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7019 (abort) [!defined abort]: Rename to ...
7020 (emacs_abort): ... new name.
7021 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7022 the place of the old 'abort' in emacs.c.
7023 * w32.c, w32fns.c (abort): Do not #undef.
7024 * w32.c (emacs_abort): Rename from w32_abort.
7026 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7028 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7029 offsets[j].dv, since the y axis of the screen coordinates points
7030 down, while the y axis of the font definition coordinates points
7031 up. This fixes display of Arabic diacritics such as KASRA and
7032 KASRATAN. (Bug#11860)
7034 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7036 Be more systematic about _setjmp vs setjmp.
7037 * alloc.c (test_setjmp, mark_stack):
7038 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7039 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7040 (png_load, my_error_exit, jpeg_load):
7041 * process.c (send_process_trap, send_process):
7042 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7043 The underscored versions are up to 30x faster on some hosts.
7044 Formerly, the code used setjmp+longjmp sometimes and
7045 _setjmp+_longjmp at other times, with no particular reason to
7046 prefer setjmp+longjmp.
7048 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7050 Fix minor problem found by static checking.
7051 * buffer.c (Fdelete_all_overlays): Return nil.
7053 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7055 * buffer.c (Fdelete_all_overlays): New function.
7057 2012-09-03 Chong Yidong <cyd@gnu.org>
7059 * gtkutil.c: Add extern decl for Qxft.
7061 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
7063 * emacs.c, eval.c: Use bool for boolean.
7064 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
7065 (malloc_using_checking) [DOUG_LEA_MALLOC]:
7066 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
7067 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
7068 (main, decode_env_path, Fdaemon_initialized):
7069 * eval.c (call_debugger, Finteractive_p, interactive_p):
7070 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
7071 (maybe_call_debugger, Fbacktrace):
7072 * process.c (read_process_output, exec_sentinel):
7073 Use bool for booleans.
7074 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
7075 All callers changed.
7076 * eval.c (interactive_p): Omit always-true boolean argument
7077 EXCLUDE_SUBRS_P. All callers changed.
7078 * dispextern.h, lisp.h: Reflect above API changes.
7079 * firstfile.c (dummy): Use the address of 'main', whose signature
7080 won't change, instead of the address of 'initialize', whose
7081 signature just changed from int to bool.
7082 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7083 * msdos.c (fatal_error_in_progress): ... from here.
7084 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7086 (redisplay_internal, unwind_redisplay): Simply clear
7087 REDISPLAYING_P when unwinding, instead of saving its previous,
7088 always-false value and then restoring it.
7090 Clean up some extern decls.
7091 Mostly, this hoists extern decls out of .c files and into .h files.
7092 That way, we're more likely to catch errors if the interfaces change.
7093 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7094 declare xg_mark_data.
7095 * dispextern.h (x_frame_parm_handlers):
7097 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
7098 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
7099 (Qultra_bold, Qoblique, Qitalic):
7100 Move extern decl here from .c file.
7101 * alloc.c (xg_mark_data) [USE_GTK]:
7103 * eval.c (Qlexical_binding):
7104 * fns.c (time) [!HAVE_UNISTD_H]:

7110 * process.c (QCfamily, QCfilter):
7111 * widget.c (free_frame_faces):
7112 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
7113 * xfont.c (x_clear_errors):
7114 * xterm.c (x_frame_parm_handlers):
7115 Remove now-redundant extern decls.
7116 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7117 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7119 * xfaces.c: Remove unnecessary static decls.
7120 * xterm.c (updating_frame): Remove decl of nonexistent object.
7122 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7123 when building globals.h, as the objects that are not built on
7124 this host are not needed to compile C files on this host.
7126 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
7128 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
7130 * frame.h: Add missing prototype for x_wm_set_size_hint.
7132 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

7142 (make_buffer_string, make_buffer_string_both)
7143 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

7166 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
7168 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
7169 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

7174 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
7176 2012-09-01 Eli Zaretskii <eliz@gnu.org>
7178 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7179 more than one grapheme cluster passed to the shaper: compute the
7180 offset adjustment values separately for each cluster. (Bug#11860)
7182 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7183 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7184 about implicit conversions from integer to pointer.
7186 2012-09-01 Daniel Colascione <dancol@dancol.org>
7188 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7189 system used too early.
7191 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
7193 Better seed support for (random).
7194 * emacs.c (main): Call init_random.
7195 * fns.c (Frandom): Set the seed from a string argument, if given.
7196 Remove long-obsolete Gentzel cruft.
7197 * lisp.h, sysdep.c (seed_random): Now takes address and size, not long.
7198 (init_random): New function.
7200 2012-09-01 Daniel Colascione <dancol@dancol.org>
7202 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
7203 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
7204 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
7205 x_wm_set_size_hint, x_query_colors, x_real_positions,
7206 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
7207 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
7208 all of which have been moved to common code.
7210 * xfaces.c: Include TERM_HEADER instead of listing all possible
7211 window-system headers.
7213 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

7217 directly accessing frame internals.
7219 * w32font.h: Include font.h. Define syms_of_w32font and
7222 * process.c: Include TERM_HEADER instead of listing all possible
7223 window-system headers.
7225 * nsterm.h: Remove declarations now in frame.h.
7226 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
7228 * menu.c: Include TERM_HEADER instead of listing all possible
7229 window-system headers.
7231 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
7234 * keyboard.c: Include TERM_HEADER instead of listing all possible
7235 window-system headers.
7237 * image.c: Include TERM_HEADER instead of listing all possible
7238 window-system headers. Declare Vlibrary_cache when compiling for
7241 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
7242 window system declarations.
7244 * frame.h: Move common functions here: set_frame_menubar,
7245 x_set_window_size, x_sync, x_get_focus_frame,
7246 x_set_mouse_position, x_set_mouse_pixel_position,
7247 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
7248 x_char_width, x_char_height, x_pixel_width, x_pixel_height,

7267 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
7268 the current window system; include in list of objects to link into
7271 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7273 Remove mark_ttys function and fix tty_display_info initialization.
7274 * lisp.h (mark_ttys): Remove prototype.
7275 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
7276 to mark_ttys because all possible values of 'top_frame' slot are
7277 the frames which are reachable from Vframe_list.
7278 * term.c (mark_ttys): Remove.
7279 (init_tty): Safely initialize 'top_frame' slot with Qnil.
7281 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7283 Change struct frame bitfields from unsigned char to unsigned.
7284 * frame.h (struct frame): Change type of 'display_preempted',
7285 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
7286 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
7287 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
7288 bitfields from unsigned char to unsigned.
7290 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7292 Remove unused member of struct x_output and struct w32_output.
7293 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
7294 * w32term.h (struct w32_output): Likewise.
7296 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
7298 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
7299 does not become zero (Bug#12234).
7301 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
7303 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
7304 for GCC 4.7.1 x86-64.
7306 2012-08-30 Glenn Morris <rgm@gnu.org>
7308 * lread.c (init_lread): For out-of-tree builds, only add the
7309 source directory's site-lisp dir to the load-path if it exists,
7310 consistent with in-tree builds. (Bug#12302)
7312 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
7314 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
7315 button_values to NULL. Call setStykeMask so dialogs get a close button.
7316 (windowShouldClose:): Set window_closed.
7317 (dealloc): New member, free button_values.
7318 (process_dialog:): Make member function. Remove window argument,
7319 replace window with self. Count buttons and allocate and store values
7321 (addButton:value:row:): value is int with the name tag. Call setTag
7322 with tag. Remove return self, declare return value as void.
7323 (addString:row:): Remove return self, declare return value as void.
7324 (addSplit): Remove return self, declare return value as void.
7325 (clicked:): Remove return self, declare return value as void.
7326 Set dialog_return to button_values[seltag]. Code formatting change.
7327 (initFromContents:isQuestion:): Adjust call to process_dialog.
7328 Code formatting change.
7329 (timeout_handler:): Set timer_fired to YES.
7330 (runDialogAt:): Set timer_fired to NO.
7331 Handle click on close button as quit.
7333 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7334 Add window_closed and button_values. Add void as return value for
7335 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7336 Add process_dialog as new member.
7338 2012-08-28 Eli Zaretskii <eliz@gnu.org>
7340 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
7341 is not one of the heaps we manage. (Bug#12242)
7343 2012-08-28 Glenn Morris <rgm@gnu.org>
7345 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
7347 2012-08-28 Martin Rudalics <rudalics@gmx.at>
7349 * window.c (Fset_window_configuration): Remove handling of
7350 auto-buffer-name window parameter. Install revision of reverted
7353 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
7355 Do not allow to set major mode for a dead buffer.
7356 * buffer.c (Fset_buffer_major_mode): Signal an error
7357 if the buffer is dead.
7358 (Fother_buffer, other_buffer_safely): Remove redundant
7361 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
7363 Always use set_buffer_if_live to restore original buffer at unwind.
7364 * buffer.h (record_unwind_current_buffer): New function.
7365 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
7366 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
7367 * undo.c, window.c: Adjust users.
7368 * buffer.c (set_buffer_if_live): Fix comment.
7370 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
7372 Fix usage of set_buffer_internal.
7373 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
7374 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
7375 * coding.c (decode_coding): Omit redundant test.
7376 * fileio.c (decide_coding_unwind): Likewise.
7377 * fns.c (secure_hash): Likewise.
7378 * insdel.c (modify_region): Likewise.
7379 * keyboard.c (command_loop_1): Likewise.
7380 * print.c (PRINTFINISH): Likewise.
7381 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
7383 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

7401 (change_frame_size_1, sit_for):
7402 Use bool for boolean.
7403 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
7404 and remove last int (actually boolean) argument, which was always 0.
7405 All callers changed.
7406 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
7407 * dispextern.h (struct composition_it): Use bool for boolean.
7408 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
7409 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
7410 * dired.c (file_name_completion):
7411 Use bool for boolean. (This was missed in an earlier change.)
7413 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7415 * window.c (Fset_window_configuration): Revert first part of
7418 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
7420 * nsterm.h (NSPanel): New class variable dialog_return.
7422 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
7423 Initialize dialog_return.
7424 (windowShouldClose:): Use stop instead of stopModalWithCode.
7425 (clicked:): Ditto, and also set dialog_return (Bug#12258).
7426 (timeout_handler:): Use stop instead of abortModal. Send a dummy
7428 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
7431 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

7443 Use bool for booleans.
7444 * dired.c (file_name_completion):
7445 * process.h (fd_callback):
7446 Omit int (actually boolean) argument. It wasn't being used.
7448 * composite.h, lisp.h: Reflect above API changes.

7472 * fileio.c (Finsert_file_contents):
7473 Use bool for booleans.
7474 * coding.h, lisp.h: Reflect above API changes.
7475 * coding.c: Remove unnecessary static function decls.
7476 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
7477 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
7478 not a boolean 'int', since callers never look at the return value.
7479 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
7480 * coding.h (decoding_buffer_size, encoding_buffer_size)
7481 (emacs_mule_string_char): Remove unused extern decls.
7482 (struct iso_2022_spec, struct coding_system):
7483 Use 'unsigned int : 1' for boolean fields, since there's more than one.
7484 (struct emacs_mule_spec): Remove unused field 'full_support'.
7485 All initializations removed.
7486 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
7488 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7490 Fix spare memory change (Bug#12286).
7491 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7492 (valid_lisp_object_p): Likewise.
7494 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7496 * window.c (Fset_window_configuration): Record any window's old
7497 buffer if it's replaced (see Bug#8789). If the new current
7498 buffer doesn't appear in the selected window, go to its old
7501 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7503 Special MEM_TYPE_SPARE to denote reserved memory.
7504 * alloc.c (enum mem_type): New memory type.
7505 (refill_memory_reserve): Use new type for spare memory.
7506 This prevents live_cons_p and live_string_p from incorrect
7507 detection of uninitialized objects from spare memory as live.
7509 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7512 * Makefile.in (.PHONY): versioclean -> versionclean.
7514 Remove unused external symbols.
7515 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7516 * window.c (Qwindow_valid_p, decode_valid_window):
7517 Now static, not extern.
7518 * data.c (Qinterval): Remove; unused.
7519 (syms_of_data): Do not define 'interval'.
7520 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7521 * window.h (decode_valid_window):
7524 * character.c, charset.c, chartab.c: Use bool for booleans.
7525 * character.c (lisp_string_width, string_count_byte8)
7526 (string_escape_byte8):

7534 (char_table_set_range, optimize_sub_char_table)
7535 (map_sub_char_table):
7536 Use bool for boolean.
7537 * character.c (str_to_unibyte): Omit last boolean argument; it was
7538 always 0. All callers changed.
7539 * character.h, charset.h: Adjust to match previous changes.
7540 * character.h (char_printable_p): Remove decl of nonexistent function.
7541 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7542 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7543 are all boolean, so make them single-bit bitfields.
7545 * lisp.h (ASET): Remove attempt to detect side effects.
7546 It was meant to be temporary and it often doesn't work,
7547 because when IDX has side effects the behavior of IDX==IDX
7548 is undefined. See Stefan Monnier in
7549 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7551 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7553 * lisp.h (functionp): New function (extracted from Ffunctionp).
7554 (FUNCTIONP): Use it.
7555 * eval.c (Ffunctionp): Use it.
7557 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7559 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7560 as that's faster and simpler than static storage. Don't bother
7561 with the g_main_context_query overhead if g_main_context_pending
7562 says no events are pending.
7563 (gfds, gfds_size): Remove these static vars.
7564 (xgselect_initialize): Remove; no longer needed.
7565 All uses and decls removed.
7567 * emacs.c (fatal_error_signal_hook): Remove.
7568 All uses removed. This leftover from old code was always 0.
7570 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7571 * casefiddle.c (casify_object, casify_region):
7572 * casetab.c (set_case_table):
7573 * category.c, category.h (word_boundary_p):
7574 * category.h (CHAR_HAS_CATEGORY):
7575 Use bool for booleans, instead of int.
7577 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7579 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7581 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7583 On assertion failure, print backtrace if available.
7584 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7585 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7586 * Makefile.in (LIB_EXECINFO): New macro.
7589 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7590 * bytecode.c (exec_byte_code):
7591 * callint.c (check_mark, Fcall_interactively):
7592 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7593 (getenv_internal, sync_process_alive, call_process_exited):
7594 * lisp.h (USE_SAFE_ALLOCA):
7595 Use bool for booleans, instead of int.
7596 * lisp.h, process.h: Adjust prototypes to match above changes.
7597 * callint.c (Fcall_interactively): Don't assume the mark's
7598 offset fits in 'int'.
7600 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7602 * buffer.c, buffer.h: Use bool for boolean.
7603 * buffer.c (reset_buffer_local_variables)

7609 (mmap_enlarge, mmap_set_vars):
7610 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7611 Use bool for booleans, instead of int.
7612 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7613 since the 1-or-0 return value is always ignored anyway.
7614 (mmap_initialized_p):
7615 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7616 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7618 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7620 * bidi.c: Use bool for boolean.
7621 This is a bit more readable, and makes the text segment of bidi.o
7622 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7623 Presumably it's faster too.
7624 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

7629 (bidi_explicit_dir_char, bidi_level_of_next_char)
7630 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7631 Use bool for booleans, instead of int.
7632 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7633 (bidi_unshelve_cache): Adjust decls to match code.
7635 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7637 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7640 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7642 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7643 * atimer.h: Include <stdbool.h>.
7645 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7647 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7648 compile time tests instead of run time tests on systems that do
7650 (FRAME_MAC_P): Remove leftover from deleted code.
7651 * frame.c (syms_of_frame): Remove leftover from deleted code.
7653 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7655 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7657 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7659 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7660 Otherwise, the compiler complains about (A?B:C) where B is void
7661 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7662 (fontset_add): Return void, for FONTSET_ADD.
7664 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7666 * alloc.c: Use bool for booleans.
7667 (gc_in_progress, abort_on_gc)
7668 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7669 (dont_register_blocks) [GC_MALLOC_CHECK]:
7670 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.

7672 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7673 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7674 (mark_stack, valid_pointer_p, make_pure_string)
7675 (Fgarbage_collect, survives_gc_p, gc_sweep):
7676 Use bool for booleans, instead of int.
7677 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7678 Remove unused local.
7679 * alloc.c (PURE_POINTER_P):
7680 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7681 * editfns.c (Fformat):
7682 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7684 * fns.c (sweep_weak_table):
7685 * lisp.h (suppress_checking, push_message, survives_gc_p)
7686 (make_pure_string, gc_in_progress, abort_on_gc):
7687 * lread.c (readchar, read1):
7688 * print.c (Fprin1_to_string):
7689 * xdisp.c (push_message):
7690 Use bool for booleans affected directly or indirectly by
7693 Make recently-introduced setters macros.
7694 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7695 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7696 (set_fontset_default, set_fontset_fallback): Rename from their
7697 upper-case counterparts, and make them functions rather than macros.
7698 This is more consistent with the other recently-introduced setters.
7699 These don't need to be inline, since they're local.
7701 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7703 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7704 the loop (Bug#12247).
7706 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7708 * lisp.h (vcopy): Use memcpy rather than our own loop.
7709 This fixes a performance regression introduced by the recent
7710 addition of vcopy. This means 'vcopy' will need to be modified
7711 for a copying collector, but that's OK. Also, tighten the
7712 checking in the assertion.
7714 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7716 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7717 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7718 non-base glyph for the width of the base character, according to
7719 what x_draw_composite_glyph_string_foreground expects.
7720 Generate WADJUST value according to composition_gstring_width's
7721 expectations, to produce correct width of the composed character.
7722 Reverse the sign of the DU offset produced by ScriptPlace.

7808 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7810 Rely on <config.h> + <unistd.h> to declare 'environ',
7811 as gnulib does this if the system doesn't.
7812 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

8681 2012-08-04 Eli Zaretskii <eliz@gnu.org>
8683 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
8684 * w32.c (init_environment): Change the default values of many
8685 environment variables in dflt_envvars[] to NULL, to avoid pushing
8686 them into environment when they were not already defined.
8687 Remove the code that deletes site-lisp subdirectories from the default
8688 value of EMACSLOADPATH, as it is no longer needed.
8689 (check_windows_init_file): Now external, not static.
8690 Use Vload_path as is, without adding anything, as this function is now
8691 called when Vload_path is already set up.
8693 * w32.h (check_windows_init_file): Add prototype.
8695 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
8696 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
8697 compatibility with Posix platforms.
8698 (main): Move the call to check_windows_init_file to here from
8700 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
8701 any, in the DEFALT argument into the root of the Emacs build or
8702 installation tree, as appropriate.
8704 * callproc.c (init_callproc_1): Call decode_env_path instead of
8705 doing its equivalent by hand.
8706 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
8707 the code that sets Vexec_path run on MS-Windows.
8709 * lread.c (init_lread): Add comments to #ifdef's.
8711 * msdos.c (dos_set_window_size, IT_update_begin)

8719 Now constants, not macros.
8721 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
8723 Remove unnecessary casts involving pointers.
8724 These casts are no longer needed now that we assume C89 or later,
8725 since they involve casting to or from void *.
8726 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
8727 (make_pure_float, make_pure_vector):
8728 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

8737 (x_get_window_property, x_get_window_property_as_lisp_data):
8738 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8739 Remove unnecessary pointer casts.
8740 * alloc.c (record_xmalloc): New function.
8741 * lisp.h (record_xmalloc): New decl.
8742 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8743 more like a function. This is because the pointer cast is not
8744 needed. All uses changed.
8745 * print.c (print_string, print_error_message): Avoid length recalc.
8747 Improve fix for macroexp crash with debugging (Bug#12118).
8748 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8749 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8750 not supposed to be invoked from the garbage collector.
8751 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
8752 (gc_aset): New function, which is like ASET but can be
8753 used in the garbage collector.
8754 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

8766 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
8767 (map_w32_filename): Improve commentary. Simplify switch.
8768 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
8769 headers (most versions of MinGW w32api don't).
8770 (get_security_info, create_symbolic_link)
8771 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
8773 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
8774 in the argument file name.

8777 (sys_rename): Diagnose renaming of a symlink when the user doesn't
8778 have the required privileges.
8779 (get_file_security_desc_by_name): Rename from
8780 get_file_security_desc.
8781 (stat_worker): New function, with most of the guts of 'stat', and
8782 with addition of handling of symlinks and support for 'lstat'.
8783 If possible, get file's attributes and security information by
8784 handle, not by name. Produce S_IFLNK bit for symlinks, when
8785 called from 'lstat'.
8786 (stat, lstat): New functions, call 'stat_worker'.
8787 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8788 symlinks when the underlying filesystem supports them.
8790 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8792 Fix macroexp crash on Windows with debugging (Bug#12118).
8793 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8794 checking subscripts; problem introduced with the recent
8795 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8796 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8797 since it's used in non-static inline functions now.
8799 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8800 Don't assume buffer size fits in 'int'. Remove unused local.
8802 Use C99-style 'extern inline' if available.

8817 * category.c (CATEGORY_INLINE):
8818 * character.c (CHARACTER_INLINE):
8819 * charset.c (CHARSET_INLINE):
8820 * composite.c (COMPOSITE_INLINE):
8821 * dispnew.c (DISPEXTERN_INLINE):
8822 * sysdep.c (SYSTIME_INLINE):
8823 Define to EXTERN_INLINE, so that the corresponding functions
8824 are compiled into code.
8825 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8826 (INLINE_HEADER_END): New macros.
8827 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8849 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8851 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8852 This how ASET and AREF are supposed to work, and makes
8853 it easier to think about future improvements. See
8854 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8855 * charset.h (set_charset_attr): New function.

9108 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
9109 does that unconditionally. Remove file, which is now empty.
9111 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
9114 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>
9116 Export to GDB most of lisp.h's remaining object-like macros.

9232 * w32inevt.c: Include w32inevt.h.
9233 (w32_read_console_input): New inline function, calls either
9234 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
9235 w32_console_unicode_input.
9236 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
9237 (w32_kbd_patch_key, key_event): Use the codepage returned by
9238 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
9239 (key_event): use uChar.UnicodeChar only if
9240 w32_console_unicode_input is non-zero.

9267 * alloc.c (listn): Fix the order the arguments are consed onto the
9270 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
9271 enumeration constants, as PURE and HEAP are too general, and clash
9272 with other headers and sources, such as gmalloc.c and the
9273 MS-Windows system headers. All users changed.
9275 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9277 Revert last save_excursion_save and save_excursion_restore changes.
9278 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

9288 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
9290 Improve GDB symbol export (Bug#12036).
9291 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
9292 arms of an 'if', not using conditional expressions; otherwise GDB
9293 complains about the types in the unevaluated arm when the argument
9294 is an integer literal.
9295 (xgetint): Simplify expression.
9296 * alloc.c (gdb_make_enums_visible): New constant. This ports to
9297 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
9298 Zaretskii in <http://bugs.gnu.org/12036#13>.
9299 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
9300 needed now that we have gdb_make_enums_visible.
9301 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
9302 (enum enum_USE_LSB_TAG):
9303 New enum types, packaging up enums that need to be exported to GDB.
9305 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

9321 * xdisp.c (syms_of_xdisp): Likewise.
9322 * xfns.c (syms_of_xfns): Likewise.
9324 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9326 Fast save_excursion_save and save_excursion_restore.
9327 * lisp.h (struct Lisp_Excursion): New data type.
9328 (PVEC_EXCURSION): New pseudovector type.
9329 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
9330 to deal with it. Adjust comments.
9331 (init_marker, attach_marker): New prototype.
9332 (unchain_marker): Adjust prototype.
9333 * marker.c (attach_marker): Change to global.

9341 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9343 Fix export of symbols to GDB (Bug#12036).
9344 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
9345 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9346 emacs.c, as this is a more-suitable home. Had this been done earlier
9347 the fix for 12036 would have avoided some of the problems noted in
9348 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9349 would have been more obvious.
9350 * emacs.c: Do not include <verify.h>; no longer needed.
9351 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9352 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9353 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9354 Remove; now done in lisp.h.
9355 * lisp.h (PUBLISH_TO_GDB): New macro.

9357 (DATA_SEG_BITS): Use it.
9358 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
9359 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9360 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9361 not be usable in #if. This simplifies things.
9363 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9365 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9367 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9369 Simplify export of symbols to GDB (Bug#12036).
9370 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9371 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9372 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9373 Adjust to changes in lisp.h and emacs.c, by using
9374 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9375 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9376 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9377 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9378 instead of gdb_valbits.
9379 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9380 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9381 instead of gdb_array_mark_flag.
9382 (xboolvector): Get size from $->size, not $->header.size.
9383 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9384 (xreload, hook-run, hookpost-run): Remove.
9385 * emacs.c: Include <verify.h>.
9386 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9387 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9389 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9390 (gdb_USE_LSB_TAG): New enum constants.
9391 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9392 Also define these as enum constants, so they're visible to GDB.
9393 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9394 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9395 as constants, so they're visible to GDB.
9396 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
9397 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9398 Now enum constants, not macros, so they're visible to GDB.
9399 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9400 more convenient now. All uses changed.
9401 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9402 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9404 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
9406 Explicitly free restriction data that are not needed anymore.
9407 * editfns.c (save_restriction_restore): Free restriction data.
9409 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
9411 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9412 add argument, tune behavior, and adjust all callers.
9414 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9416 Use typedef for EMACS_INT, EMACS_UINT.
9417 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9418 than macros. This simplifies debugging in the usual case, since
9419 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9420 and it allows expressions involving EMACS_INT casts.
9421 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9423 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
9425 * nsterm.m (ns_read_socket): Return early if there is a modal
9428 2012-07-25 Martin Rudalics <rudalics@gmx.at>
9430 * frame.c (Fredirect_frame_focus): In doc-string don't mention
9431 that FOCUS-FRAME can be omitted.
9433 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9435 Adjust buffer text indirection counters at the end of Fkill_buffer.
9436 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9437 buffer is definitely dead. This should really fix an issue reported
9438 by Christoph Scholtes again. (Bug#12007).
9439 (init_buffer_once): Initialize indirection counters of
9440 buffer_defaults and buffer_local_symbols (for sanity and safety).
9442 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9444 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9445 and continuation glyphs on tooltip frames, leave them at zero.
9446 Avoids continued lines in tooltips. (Bug#11832)
9448 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
9450 Simplify copy_overlay.
9451 * buffer.c (copy_overlay): Simplify. Use build_marker.
9452 * lisp.h (struct Lisp_Overlay): Restore comment with minor tweaks.
9454 2012-07-23 Eli Zaretskii <eliz@gnu.org>
9456 * print.c (print_object): Don't crash when a frame's name is nil
9457 or invalid. (Bug#12025)
9459 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
9460 it signals an error when a tooltip frame is being created.
9462 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9464 Cleanup miscellaneous objects allocation and initialization.
9465 * alloc.c (allocate_misc): Change to static. Add argument to
9466 specify the subtype. Adjust comment and users.
9467 (build_overlay): New function.
9468 * buffer.c (copy_overlays, Fmake_overlay): Use it.
9469 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
9470 (allocate_misc): Remove prototype.
9471 (build_overlay): Add prototype.
9473 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9475 Swap buffer text indirection counters in Fbuffer_swap_text.
9476 * buffer.c (Fbuffer_swap_text): Swap indirections too.

10278 (menu_separator_name_p):
10279 * nsmenu.m (ns_update_menubar):
10280 Prefer memcmp to strncmp when either will do.
10281 * nsterm.m: Include <ftoastr.h>.
10283 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10284 Prefer snprintf to strncpy.
10285 * nsterm.m (ns_term_init):
10286 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10287 * nsterm.m (ns_term_init):
10288 Avoid the need for strncpy, by using build_string or
10289 make_unibyte_string directly. Use dtoastr, not snprintf.
10290 * process.c (Fmake_network_process): Diagnose service names that
10291 are too long, rather than silently truncating them or creating

10362 We include usg5-4-common.h, which defines them both.
10364 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10365 O_RDONLY already includes it).
10367 Stop ns builds setting the EMACSLOADPATH environment variable.
10368 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10369 Now it does not set EMACSLOADPATH, just returns the load-path string.
10370 * nsterm.h: Update accordingly.
10371 * lread.c [HAVE_NS]: Include nsterm.h.
10372 (init_lread) [HAVE_NS]: Use ns_load_path.
10373 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10375 2012-07-09 Glenn Morris <rgm@gnu.org>
10377 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10378 since the included bsd-common.h does so.
10380 Stop ns builds setting the EMACSPATH environment variable.
10381 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10382 (ns_init_paths): Do not set EMACSPATH.
10383 * nsterm.h (ns_exec_path): Add it.
10384 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10387 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10389 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10391 * process.c (wait_reading_process_output): 'waitchannels' was unset
10392 when read_kbd || !NILP (wait_for_cell); fix this.
10394 Add GCC-style 'const' attribute to functions that can use it.
10395 * character.h (char_resolve_modifier_mask):
10396 * keyboard.h (make_ctrl_char):
10397 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10398 (init_character_once, next_almost_prime, init_fns, init_image)
10399 (flush_pending_output, init_sound):
10400 * mem-limits.h (start_of_data):
10401 * menu.h (finish_menu_items):
10402 Add ATTRIBUTE_CONST.
10403 * emacs.c (DEFINE_DUMMY_FUNCTION):
10404 Declare the dummy function with ATTRIBUTE_CONST.
10405 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
10406 Add decls with ATTRIBUTE_CONST.
10408 Minor improvements to make_formatted_string.
10409 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10410 where int is good enough, as vsprintf returns an int.
10411 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10413 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10415 Use make_formatted_string to avoid double length calculation.
10416 * lisp.h (make_formatted_string): New prototype.
10417 * alloc.c (make_formatted_string): New function.
10418 * buffer.c (Fgenerate_new_buffer_name): Use it.
10419 * dbusbind.c (syms_of_dbusbind): Likewise.

10431 2012-07-09 Glenn Morris <rgm@gnu.org>
10433 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
10434 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
10435 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

10437 * callproc.c [HAVE_NS]: Include nsterm.h.
10438 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10440 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10442 Move marker debugging code under MARKER_DEBUG.
10443 * marker.c (MARKER_DEBUG): Move marker debugging code under
10444 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10445 for bootstrap with --enable-checking (~3x slowdown reported
10446 by Juanma Barranquero <lekktu@gmail.com>).
10447 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10449 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10451 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10452 See <http://bugs.gnu.org/11825#29>.
10454 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10456 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10457 has no font, use the frame's font. (Bug#11813)
10458 (display_line): Add commentary about displaying truncation glyphs
10460 (produce_special_glyphs): Move here from term.c.
10462 * term.c (produce_special_glyphs): Move to xdisp.c.
10464 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10467 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10469 * xdisp.c (display_line): Avoid warning about implicit declaration
10472 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10474 * lisp.h: Remove empty conditional.
10476 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10478 * lread.c (load_path_check): Now static.
10480 Fix some minor --with-ns problems found by static checking.
10481 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10482 (x_set_font) [!HAVE_X_WINDOWS]:
10483 * image.c (xpm_load_image) [HAVE_NS]:
10484 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10485 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10486 Remove unused local.
10487 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10488 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10489 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10490 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10491 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10492 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10493 Fix pointer signedness problem.
10494 * xfaces.c (FRAME_X_FONT_TABLE):
10495 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10497 2012-07-07 Glenn Morris <rgm@gnu.org>
10499 * lread.c (load_path_check): New function, split from init_lread.
10500 (init_lread): Reorganize. Motivation:
10501 If EMACSLOADPATH is set, check/warn about that rather than the
10502 defaults, which we are not going to use. Hence we can remove
10503 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10504 Don't warn if site-lisp directories are missing.
10505 If not installed, start from a blank load-path, since
10506 PATH_LOADSEARCH refers to the eventual installation directories.
10508 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10510 Support truncation and continuation glyphs on GUI frames, when
10511 fringes are disabled. (Bug#11832)
10512 * xdisp.c (init_iterator): Get dimensions of truncation and
10513 continuation glyphs even if on GUI frames.
10514 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10515 or both, are absent.
10516 (start_display, move_it_in_display_line_to): Handle the case of a
10517 GUI frame without a fringe to display continuation or truncation
10519 (insert_left_trunc_glyphs): Support GUI frames: make sure
10520 truncation glyphs overwrite enough glyphs from the current line to
10521 have sufficient space in pixels.
10522 (display_line): Support truncation and continuation glyphs on GUI
10523 frames. If some spare pixels are left on the line after inserting
10524 the truncation glyphs, fill that space with a stretch glyph of a
10525 suitably computed width.
10527 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10528 produce_glyphs, to support GUI sessions.
10530 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10532 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10534 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10536 Do not require float-time's arg to fit in time_t (Bug#11825).
10537 This works better on hosts where time_t is unsigned, and where
10538 float-time is applied to the (negative) difference between two times.
10539 * editfns.c (decode_time_components): Last arg is now double *,
10540 not int *, and means to store all the result as a double, without
10541 worrying about whether the seconds part fits in time_t.
10542 All callers changed.
10543 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10544 All callers changed.
10545 (Ffloat_time): Do not fail merely because the specified time falls
10546 outside of time_t range.
10548 2012-07-07 Glenn Morris <rgm@gnu.org>
10550 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10551 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10552 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10554 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10556 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10557 Update dependencies.

10565 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10566 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10567 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10568 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10570 * xfont.c (compare_font_names): Redo to omit the need for casts.
10572 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10574 * xfns.c (Fx_change_window_property): Doc fix.
10575 * w32fns.c (Fx_change_window_property): Doc fix.
10577 * w32fns.c (Fx_window_property): Accept the same arguments as the
10578 X Windows version. Doc fix.
10579 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10581 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10582 Eli Zaretskii <eliz@gnu.org>
10584 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10585 Windows-specific code from nt/config.nt moved here.
10586 Obsolete settings removed.
10588 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10590 * process.c: Avoid unnecessary calls to gettime.
10591 (wait_reading_process_output): Don't get the time of day
10592 when gobbling data immediately and not waiting, as there's no need
10593 for it in that case. This removes a FIXME.
10595 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10597 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10598 is defined (Bug#11768).
10600 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10602 Fix marker debugging code.
10603 * marker.c (byte_char_debug_check): Do not perform the check
10604 if buffer is not multibyte.
10605 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10606 Call byte_char_debug_check with correct arguments.
10608 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10610 Compile marker debugging code only if ENABLE_CHECKING is defined.
10611 * marker.c (byte_char_debug_check, count_markers):
10612 Use only if ENABLE_CHECKING is defined.
10613 (byte_debug_flag): Remove.
10614 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10615 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10617 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10619 Avoid code repetition in marker-related functions.
10620 * marker.c (attach_marker): New function.

10624 Consistently rename charno to charpos.
10625 (marker_position): Add eassert.
10626 (marker_byte_position): Convert to eassert.

10642 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10643 (save_restriction_save): Use build_marker.
10644 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10645 * window.c (save_window_save): Likewise.
10647 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10649 Do not use Fdelete_overlay in delete_all_overlays

10652 (delete_all_overlays, Fdelete_overlay): Use it.
10653 * minibuf.c (get_minibuffer): Fix comment.
10655 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10657 Port to OpenBSD 5.1 amd64.
10658 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10659 This is needed for OpenBSD, and should be harmless on all BSD systems.
10660 Also, include <sys/sysctl.h>, as it should be available on all
10661 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10662 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10663 use p_pid member, not kp_proc.pid.
10665 2012-07-06 Glenn Morris <rgm@gnu.org>
10667 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10669 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10671 More xmalloc and related cleanup.

10680 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10682 Omit needless casts involving void * pointers and allocation.
10683 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10684 as the former is more robust if P's type is changed.
10685 Prefer xzalloc to xmalloc + memset 0.
10686 Simplify malloc-or-realloc to realloc.
10687 Don't worry about xmalloc returning a null pointer.
10688 Prefer xstrdup to xmalloc + strcpy.
10689 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10691 * keyboard.c (apply_modifiers_uncached): Prefer local array to

10696 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10697 hscroll is larger than the line width. Fixes long and futile
10698 looping inside extend_face_to_end_of_line (on a TTY) producing
10699 glyphs that are not needed and thrown away.
10701 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

10717 followed by gtk_box_set_homogeneous (Bug#11768).
10718 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10719 (update_theme_scrollbar_width, xg_create_scroll_bar):
10720 Use gtk_scrollbar_new (Bug#11768).

10722 (is_box_type): New function (Bug#11768).
10723 (xg_tool_item_stale_p): Call is_box_type.
10724 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10725 with default display (Bug#11768).
10727 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10729 * xdisp.c (window_hscroll_limited): New function.
10730 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10731 coordinates when window's hscroll is set to insanely large
10732 values. (Bug#11857)
10734 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10803 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10804 This should be fixed in a better way; see Eli Zaretskii in
10805 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10806 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10808 * fileio.c (time_error_value): Rename from special_mtime.
10809 The old name's problems were noted by Eli Zaretskii in
10810 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10812 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10813 This variable's comment says Emacs needs at least one GDB-visible
10814 symbol of type enum pvec_type, to work around GDB problems.
10815 The symbol's value doesn't matter.
10817 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10818 that causes compilation to fail on pre-C99 compilers.
10820 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10822 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10823 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10825 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10827 * buffer.c (init_buffer_once): Fix initialization of
10828 headers for buffer_defaults and buffer_local_symbols.
10829 Reported by Juanma Barranquero <lekktu@gmail.com>.
10831 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10833 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10834 * lisp.h (enum pvec_type): Use fewer bits.
10835 (PSEUDOVECTOR_SIZE_BITS): New constant.
10836 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10837 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10838 change in pvec_type.
10839 (PSEUDOVECTOR_TYPEP): New macro.
10840 (TYPED_PSEUDOVECTORP): Use it.
10841 * fns.c (internal_equal): Adapt code to extract pvectype.
10842 * emacs.c (gdb_pvec_type): Update type.
10843 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10844 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10845 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10846 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10847 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10848 abusing vector->header.next.nbytes.
10849 (live_vector_p): Use PVEC_TYPE.
10850 (mark_object): Adapt code to extract pvectype. Use switch.
10852 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10854 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10855 Tighten new eassert a bit.
10857 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10859 Fix compilation with --enable-gcc-warnings and -O1
10860 optimization level.
10861 * doprnt.c (doprnt): Change type of tem to int, initialize
10862 to avoid compiler warning. Add eassert.
10863 * search.c (simple_search): Initialize match_byte to avoid
10864 compiler warning. Add eassert.
10866 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10868 Avoid weird behavior with large horizontal scrolls.
10869 Without this change, for example, large hscroll values would
10870 mess up Emacs's display on Fedora 15 x86, presumably due to
10871 overflows in int calculations in the display code.
10872 Also, if buffers had long lines, Emacs would freeze.
10873 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10874 (set_window_hscroll): New function, containing the old guts of
10875 Fset_window_hscroll. Return the clipped value.
10876 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10877 This avoids the need to check against PTRDIFF_MAX.
10879 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10881 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10883 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10885 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10887 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10888 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10889 since GCC 4.4.6 issues a bogus warning for them.
10891 Fix bugs in file timestamp newness comparisons.
10892 * fileio.c (Ffile_newer_than_file_p):
10893 * lread.c (Fload): Use full timestamp resolution of files,
10894 not just the 1-second resolution, so that files that are only
10895 slightly newer still count as newer.
10896 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10897 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10899 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10901 * fileio.c: Improve handling of file time marker. (Bug#11852)
10902 (special_mtime): New function.
10903 (Finsert_file_contents, Fverify_visited_file_modtime):
10904 Use it to set special mtime values consistently.
10906 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10908 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10909 marker for non-existing file. (Bug#11852)
10911 2012-07-03 Glenn Morris <rgm@gnu.org>
10913 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10914 and did not make it into globals.h).
10916 2012-07-03 Tom Tromey <tromey@redhat.com>
10918 * window.c (Fset_window_margins, Fset_window_fringes)
10919 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10920 * textprop.c (Fprevious_property_change): No longer static.
10921 * syntax.c (Fsyntax_table_p): No longer static.
10922 * process.c (Fget_process, Fprocess_datagram_address): No longer
10924 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
10925 * keyboard.c (Fcommand_execute): No longer static.
10927 * insdel.c (Fcombine_after_change_execute): No longer static.
10928 * image.c (Finit_image_library): No longer static.
10929 * fileio.c (Fmake_symbolic_link): No longer static.
10930 * eval.c (Ffetch_bytecode): No longer static.
10931 * editfns.c (Fuser_full_name): No longer static.
10932 * doc.c (Fdocumentation_property, Fsnarf_documentation):

10936 * dired.c (Ffile_attributes): No longer static.
10937 * composite.c (Fcomposition_get_gstring): No longer static.
10938 * callproc.c (Fgetenv_internal): No longer static.
10940 * ccl.h: Remove EXFUNs.
10941 * buffer.h: Remove EXFUNs.
10942 * dispextern.h: Remove EXFUNs.
10943 * intervals.h: Remove EXFUNs.
10944 * fontset.h: Remove EXFUN.
10945 * font.h: Remove EXFUNs.
10946 * dosfns.c (system_process_attributes): Remove EXFUN.
10947 * keymap.h: Remove EXFUNs.
10948 * lisp.h: Remove EXFUNs.
10949 * w32term.h: Remove EXFUNs.
10950 * window.h: Remove EXFUNs.
10951 * xsettings.h: Remove EXFUN.
10952 * xterm.h: Remove EXFUN.
10954 2012-07-03 Glenn Morris <rgm@gnu.org>
10956 * lisp.h (Frandom): Make it visible to C.
10957 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
10958 buffer for invisible buffers. (Bug#1229)
10960 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10962 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
10963 values which aren't power of 2.
10964 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10965 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
10968 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
10970 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
10972 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10974 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10976 * alloc.c (allocate_vector_block): Remove redundant
10977 calls to mallopt if DOUG_LEA_MALLOC is defined.
10978 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10979 avoid calls to mallopt if zero_vector is returned.
10981 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10983 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10984 is enabled, avoid dereferencing NULL current_sblock if
10987 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10989 Cleanup basic buffer management.
10990 * buffer.h (struct buffer): Change layout to use generic vector
10991 marking code. Fix some comments. Change type of 'clip_changed'
10992 to bitfield. Remove unused #ifndef old.
10993 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10994 (GET_OVERLAYS_AT): Fix indentation.
10995 (for_each_per_buffer_object_at): New macro.
10996 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10997 (Fbuffer_local_variables): Use it.
10998 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
10999 * alloc.c (allocate_buffer): Adjust to match new layout of
11000 struct buffer. Fix comment.
11001 (mark_overlay): New function.
11002 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11003 Lisp area of struct buffer.
11004 (mark_object): Use it. Adjust marking of misc objects
11005 and related comments.
11007 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11009 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11010 wrapper that is not needed because the wrapped code is a no-op (zero
11011 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11012 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11014 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11016 * alloc.c (mark_buffer): Simplify. Remove prototype.
11017 (mark_object): Add comment. Reorganize marking of vector-like
11018 objects. Use CHECK_LIVE for all vector-like objects except buffers
11019 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11020 Avoid redundant calls to mark_vectorlike for bool vectors.
11022 2012-06-30 Glenn Morris <rgm@gnu.org>
11024 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11026 * epaths.in (PATH_SITELOADSEARCH): New.
11027 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11028 This is rather than relying on --enable-locallisppath elements
11029 having "site-lisp" in their names. (Bug#10208#25, 11658)
11031 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11033 * w32proc.c (sys_select): Accept and ignore one more argument.
11035 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11037 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11038 (pselect) [!MS_DOS]: Redirect to sys_select.
11040 * sysdep.c: Don't include dos.h and dosfns.h.
11042 * process.c (sys_select):
11043 * msdos.c (sys_select): Accept one more argument and ignore it.
11045 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11046 adapt data types and code to that.
11049 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11050 which clashes with the gnulib function of the same name.
11052 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11054 * font.c (font_style_to_value, font_style_symbolic)
11055 (font_prop_validate_style): Add type checks for values in
11058 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11060 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11063 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11065 * xdisp.c (try_window_id): Undo last change.
11067 * w32.c (getwd): Adjust commentary about startup_dir.
11068 (init_environment): Always call sys_access, even in non-MSVC
11069 builds. Don't chdir to the directory of the Emacs executable.
11070 This undoes code from 1997 which was justified by the need to
11071 "avoid conflicts when removing and renaming directories". But its
11072 downside was that every relative file name was being interpreted
11073 relative to the directory of the Emacs executable, which can never
11074 be TRT. In particular, it broke sys_access when called with
11075 relative file names.
11076 (sys_access): Map GetLastError to errno.
11078 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11080 * window.h (struct window): Change type of 'fringes_outside_margins'
11081 to bitfield. Fix comment. Adjust users accordingly.
11082 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
11084 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11087 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11089 * gnutls.c (emacs_gnutls_handshake):
11090 Add QUIT to make the loop interruptible.
11092 2012-06-29 Glenn Morris <rgm@gnu.org>
11094 * charset.c (init_charset): Make lack of etc/charsets fatal.
11096 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11098 * editfns.c (region_limit): Fix type mismatch.
11100 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11102 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11103 undefined. Convert from xassert to eassert.
11104 * nsmenu.m: Convert from xassert to eassert.
11105 * nsterm.m: Likewise.
11107 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
11109 * editfns.c (region_limit): Clip to narrowing (bug#11770).
11111 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11113 Avoid integer overflow on scroll-left and scroll-right.
11114 * window.c (HSCROLL_MAX): New macro.
11115 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11116 overflow when requested scroll falls outside ptrdiff_t range.
11118 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11120 * window.h (struct window): Change type of 'hscroll',
11121 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11122 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11123 Adjust users accordingly.
11124 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11125 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11126 from EMACS_INT to ptrdiff_t.
11127 (make_window): Omit redundant initialization.
11129 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
11131 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
11133 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11135 * window.h (struct window): Change type of 'use_time' and
11136 'sequence_number' from Lisp_Object to int.
11137 * frame.c (make_frame): Adjust users accordingly.
11138 * print.c (print_object): Likewise.
11139 * window.c (select_window, Fwindow_use_time, make_parent_window)
11140 (make_window): Likewise.
11142 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11144 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
11145 enabled with --enable-checking=[all,glyphs] configure option.
11146 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11147 adjust comments accordingly.
11148 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
11149 undefined, adjust comments accordingly.
11150 * image.c: Likewise.
11151 * scroll.c: Likewise.
11152 * w32fns.c: Likewise.
11153 * w32term.c: Likewise.

11156 * xfns.c: Likewise.
11157 * xterm.c: Likewise.
11159 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11161 Generalize run-time debugging checks.
11162 * dispextern.h (XASSERTS): Remove.

11184 * xfaces.c: Likewise.
11185 * xfns.c: Likewise.
11186 * xselect.c: Likewise.
11187 * xterm.c: Likewise.
11189 2012-06-27 Stefan Monnier <monnier@iro.umontreal.ca>
11191 * fns.c (maybe_resize_hash_table): Output message when growing the
11194 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
11196 * alloc.c (allocate_string_data): Remove dead code.
11197 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
11198 avoid GCC warning about unused macro.
11200 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
11202 * alloc.c (allocate_string): Omit intervals initialization.
11203 * alloc.c (make_uninit_multibyte_string): Initialize intervals

11217 * lisp.mk (lisp): Remove paths.elc.
11219 2012-06-27 Chong Yidong <cyd@gnu.org>
11221 * doc.c (Fsubstitute_command_keys): Fix punctuation.
11223 2012-06-26 John Wiegley <johnw@newartisans.com>
11225 * unexmacosx.c (copy_data_segment): Add two section names used
11226 on Mac OS X Lion: __mod_init_func and __mod_term_func.
11228 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
11229 when building with Clang.
11231 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>
11233 * eval.c (Fapply): Allow calling it with a single argument.
11235 2012-06-26 Eli Zaretskii <eliz@gnu.org>
11237 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
11238 _stricmp and _strnicmp.
11239 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.
11241 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
11243 * alloc.c (allocate_window): Zero out non-Lisp part of newly
11245 (allocate_process): Likewise for new process.
11246 (allocate_terminal): Change to use offsetof.
11247 (allocate_frame): Likewise.
11248 * frame.c (make_frame): Omit redundant initialization.
11249 * window.c (make_parent_window): Use memset.
11250 (make_window): Omit redundant initialization.
11251 * process.c (make_process): Omit redundant initialization.
11252 * terminal.c (create_terminal): Likewise.

11258 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
11260 * alloc.c: Remove build_string.
11261 * lisp.h: Define build_string as static inline. This provides
11262 a better opportunity to optimize away calls to strlen when the
11263 function is called with compile-time constant argument.
11264 * image.c (imagemagick_error): Convert to build_string.
11265 * w32proc.c (sys_spawnve): Likewise.
11266 * xterm.c (x_term_init): Likewise.
11268 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11270 Use sprintf return value instead of invoking strlen on result.
11271 In the old days this wasn't portable, since some sprintf
11272 implementations returned char *. But they died out years ago and
11273 Emacs already assumes sprintf returns int.
11274 Similarly for float_to_string.
11275 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

11283 Use sprintf or float_to_string result to avoid need to call strlen.
11284 * data.c (Fnumber_to_string):

11328 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11329 instead of truncating it to 63 (admittedly a generous limit).

11388 * dispnew.c (Fsleep_for, sit_for):
11389 * keyboard.c (kbd_buffer_get_event):
11390 * process.c (Faccept_process_output):
11391 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11392 This improves on the previous patch, which introduced a bug
11393 when time_t is unsigned and as wide as intmax_t.
11394 See <http://bugs.gnu.org/9000#51>.
11396 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11425 language ID in the event parameters.
11427 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11428 event.code, not the obscure "character set ID".
11430 2012-06-23 Chong Yidong <cyd@gnu.org>
11432 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

11455 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
11456 (TIMEVAL, system_process_attributes) [__FreeBSD__]:

11459 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
11461 Support higher-resolution time stamps (Bug#9000).
11462 The time stamps are only nanosecond-resolution at the C level,
11463 since that's the best that any real-world system supports now.
11464 But they are picosecond-resolution at the Lisp level, as that's
11465 easy, and leaves room for future OS improvements.
11467 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11470 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11471 Don't get current time unless it's needed.
11473 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11474 now provides it if it's absent.
11475 (start_atimer): Port to higher-res time stamps.
11476 Check for time stamp overflow. Don't get current time more
11477 often than is needed.
11479 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11480 Include systime.h, not time.h.
11481 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11483 * dired.c: Include stat-time.h.
11484 (Ffile-attributes): File times now have higher resolution.
11486 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11487 (struct image): Timestamp now has higher resolution.
11489 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11490 has at least microseconds now. All uses removed.
11491 (update_frame, update_single_window, update_window, update_frame_1)
11492 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11493 (duration_to_sec_usec): Remove; no longer needed.
11495 * editfns.c (time_overflow): Now extern.
11496 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
11497 (float-time, Fformat_time_string, Fcurrent_time_string)
11498 (Fcurrent_time_zone): Accept and generate higher-resolution
11500 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
11501 (decode_time_components, lisp_seconds_argument): New functions.
11502 (make_time): Now static.
11503 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11504 Report an error if the time is invalid, rather than having the caller
11507 * fileio.c: Include <stat-time.h>
11508 (Fcopy_file): Copy higher-resolution time stamps.
11509 Prefer to set the time stamp via a file descriptor if that works.
11510 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11511 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11512 (Fvisited_file_modtime, Fset_visited_file_modtime):
11513 Support higher-resolution time stamps.
11515 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11517 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11519 * image.c (prepare_image_for_display, clear_image_cache)
11520 (lookup_image): Port to higer-resolution time stamps.
11522 * keyboard.c (start_polling, bind_polling_period):
11523 Check for time stamp overflow.
11524 (read_char, kbd_buffer_get_event, timer_start_idle)
11525 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11526 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11527 Port to higher-resolution time stamps. Do not assume time_t is signed.
11528 (decode_timer): New function. Timers are now vectors of length 9,
11529 not 8, to accommodate the picosecond component.
11530 (timer_check_2): Use it.
11532 * nsterm.m (select_timeout, timeval_subtract): Remove.
11533 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11534 as they're a bit more accurate and handle overflow better.
11535 (ns_select): Change prototype to be compatible with pselect.
11536 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11537 * nsterm.h (ns_select): Adjust prototype.
11539 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11540 us-resolution time stamps.
11541 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11543 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11545 * lisp.h (time_overflow): New decl.
11546 (wait_reading_process_output): First arg is now intmax_t, not int,
11547 to accommodate larger waits.
11549 * process.h (struct Lisp_Process.read_output_delay):
11550 Now counts nanoseconds, not microseconds.
11551 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11553 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11554 (wait_reading_process_output):
11555 Port to ns-resolution time stamps.
11556 (Faccept_process_output, wait_reading_process_output):
11557 Check for time stamp overflow. Do not assume time_t is signed.
11558 (select_wrapper): Remove; we now use pselect.
11559 (Fprocess_attributes): Now generates ns-resolution time stamps.
11561 * sysdep.c: Include utimens.h. Don't include utime.h
11562 or worry about struct utimbuf; gnulib does that for us now.
11563 (gettimeofday): Remove; gnulib provides a substitute.
11564 (make_timeval): New function.
11565 (set_file_times): Now sets ns-resolution time stamps.
11566 New arg FD; all uses changed.
11567 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11568 (system_process_attributes):
11569 Now returns ns-resolution time stamp. All uses changed.
11570 Check for time stamp overflow.
11572 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11573 provides a substitute now.
11575 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11576 since it guarantees struct timespec.
11577 (EMACS_TIME): Now struct timespec, so that we can support
11578 ns-resolution time stamps.
11579 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11580 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11581 (EMACS_USECS): Remove.
11582 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11583 so multiply the arg by 1000 before storing it.
11584 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11586 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11587 Port to ns-resolution time stamps.
11588 (EMACS_TIME_NEG_P): Remove; replaced by....
11589 (EMACS_TIME_SIGN): New macro.
11590 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
11591 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
11592 (set_file_times, make_time, lisp_time_argument): Adjust signature.
11593 (make_timeval, make_lisp_time, decode_time_components): New decls.
11594 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11595 that it mishandled time_t overflow. You can't compare by subtracting!
11596 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11597 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11599 * term.c: Include <sys/time.h>.
11600 (timeval_to_Time): New function, for proper overflow wraparound.
11601 (term_mouse_position, term_mouse_click): Use it.
11603 * undo.c (record_first_change): Support higher-resolution time stamps
11604 in the undo buffer.
11605 (Fprimitive_undo): Use them when restoring time stamps.
11607 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11608 (w32_get_internal_run_time):
11609 Port to higher-resolution Emacs time stamps.
11610 (ltime): Now accepts single 64-bit integer, as that's more convenient
11613 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11615 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11616 for compatibility with pselect. Support ns-resolution time stamps.
11618 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11620 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11621 Check for time stamp overflow, and support ns-resolution time stamps.
11623 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11624 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11625 (timeval_subtract): Remove; no longer needed.
11626 (XTflash, XTring_bell, x_wait_for_event):
11627 Port to ns-resolution time stamps. Don't assume time_t is signed.
11629 2012-06-22 Chong Yidong <cyd@gnu.org>

11633 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11635 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11636 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11637 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11638 staticidx goes up to 1597 out of 1600 = 0x640.)
11640 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11642 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
11643 Otherwise, the umask might be mistakenly 0 while handling input signals.
11645 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

11654 access to `contents' member of Lisp_Vector objects with AREF and ASET
11657 2012-06-19 Chong Yidong <cyd@gnu.org>
11659 * frame.c (delete_frame): When selecting a frame on a different
11660 text terminal, do not alter the terminal's top-frame.
11662 * xdisp.c (format_mode_line_unwind_data): Record the target
11663 frame's selected window and its terminal's top-frame.
11664 (unwind_format_mode_line): Restore them.
11665 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11667 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11668 since tty frames can be explicitly named.
11669 (prepare_menu_bars): Likewise.
11671 * term.c (Ftty_top_frame): New function.
11673 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

11676 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11677 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11678 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11679 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
11680 (METER_1, METER_2): Simplify.
11682 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
11684 * data.c (Fdefalias): Return `symbol' (bug#11686).
11686 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11688 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11689 gets killed during executing of this function (Bug#11665).
11690 Try to always return Qt when the buffer has been actually killed.
11691 (Vkill_buffer_query_functions): In doc-string say that functions
11692 run by this hook should not change the current buffer.
11694 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11696 Fix recently-introduced process.c problems found by static checking.
11697 * process.c (write_queue_push, write_queue_pop, send_process):
11698 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
11699 (write_queue_pop): Fix pointer signedness problem.
11700 (send_process): Remove unused local.
11702 2012-06-17 Chong Yidong <cyd@gnu.org>
11704 * xdisp.c (redisplay_internal): No need to redisplay terminal
11705 frames that are not on top.

11913 Use an inline function on all platforms when using the union type,

12059 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12060 would mishandle a string argument "Xc" if X was a multibyte
12061 character of length 2: it would truncate after X's first byte
12062 rather than including all of X.

12113 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12115 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12116 Convert pctcpu and pctmem to Lisp float properly.

12131 bitfields where appropriate, remove unused fields.
12132 * window.h (struct window): Remove unused 'last_mark_x' and
12133 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12134 change its type from Lisp_Object to bitfield.
12135 Change type of 'force_start', 'optional_new_start',
12136 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

12143 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12144 Use 'float' consistently, rather than 'float' in most places
12145 and 'double' in a couple of places.
12147 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12149 * xdisp.c (handle_stop): Detect whether we have overlay strings
12150 loaded by testing it->current.overlay_string_index to be
12151 non-negative, instead of checking whether n_overlay_strings is
12152 positive. (Bug#11587)

12162 * search.c (search_buffer): Remove calls to
12163 r_alloc_inhibit_buffer_relocation, as it is now called by
12164 maybe_unify_char, which was the cause of relocation of buffer text
12167 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12169 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12170 for the duration of call to load_charset, to avoid problems with
12171 callers of maybe_unify_char that access buffer text through C
12174 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12175 decrement the inhibition flag, instead of just setting or
12178 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12180 Remove obsolete '#define static' cruft.
12181 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12182 This #undef was "temporary" in 2000; it is no longer needed
12183 now that '#define static' has gone away.
12184 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12185 (gray_bitmap_bits): Remove; no longer needed.
12186 All uses replaced with definiens.
12187 * xterm.c: Include "bitmaps/gray.xbm".
12189 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
12191 Clean up __executable_start, monstartup when --enable-profiling.
12192 The following changes affect the code only when profiling.
12193 * dispnew.c (__executable_start): Rename from safe_bcopy.
12194 Define only on platforms that need it.
12195 * emacs.c: Include <sys/gmon.h> when profiling.
12196 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
12197 (__executable_start): Remove decl, since lisp.h does it now.
12198 (safe_bcopy): Remove decl; no longer has that name.
12199 (main): Coalesce #if into single bit of code, for simplicity.
12200 Cast pointers to uintptr_t, since standard libraries want integers
12202 * lisp.h (__executable_start): New decl.
12204 2012-05-31 Glenn Morris <rgm@gnu.org>
12206 * image.c (Fimagemagick_types): Doc fix.
12208 2012-05-30 Jim Meyering <meyering@redhat.com>
12210 * callproc.c (Fcall_process_region): Include directory component
12211 in mkstemp error message (Bug#11586).
12213 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
12215 * alloc.c, lisp.h (make_pure_vector): Now static.
12217 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
12219 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
12220 Move to byte-run.el.
12221 (Fautoload): Do the hash-doc more carefully.
12222 * data.c (Fdefalias): Purify definition, except for keymaps.
12223 (Qdefun): Move from eval.c.
12224 * lisp.h (Qdefun): Remove.
12225 * lread.c (read1): Tiny simplification.
12227 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
12229 Do not create empty overlays with the evaporate property (Bug#9642).
12230 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12231 Bug#9642, but explicitly check that the buffer the overlay would
12232 be moved to is live and rearrange lines to make sure that errors
12233 will not put the overlay in an inconsistent state.
12234 (Fdelete_overlay): Cosmetics.
12236 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12238 * w32term.c (my_bring_window_to_top): New function.
12239 (x_raise_frame): Use handle returned by DeferWindowPos, which
12240 could be different from the original one.
12241 Call my_bring_window_to_top instead of my_set_foreground_window.
12244 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
12245 by calling BringWindowToTop.
12247 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
12248 (WM_EMACS_END): Increase by one.
12250 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12252 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12253 This avoids undefined behavior that might cause the eassert
12254 to not catch an out-of-range value.
12256 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12258 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
12259 Update dependencies.
12261 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12263 * bidi.c (bidi_mirror_char): Fix last change.
12265 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
12267 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
12268 when referring to sectname field in printf format.
12270 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
12272 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12273 Only r_alloc_inhibit_buffer_relocation needed to be added;
12274 the others were already declared.
12276 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12277 before checking whether it's out of range. Put the check inside
12279 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12281 2012-05-27 Ken Brown <kbrown@cornell.edu>
12283 * callproc.c (Fcall_process): Restore a line that was accidentally
12284 commented out in the 2011-02-13 change (bug#11547).
12286 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12288 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12289 defined on ralloc.c.
12291 * buffer.c [REL_ALLOC]: Remove prototypes of
12292 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12293 they are now on lisp.h.
12295 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12297 * search.c (search_buffer): Use it to inhibit relocation of buffer
12298 text while re_search_2 is doing its job, because re_search_2 is
12299 passed C pointers to buffer text. (Bug#11519)
12301 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12302 Update value to 24.
12304 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12305 state after an additional call to move_it_in_display_line_to, keep
12306 the values of it->max_ascent and it->max_descent found for the
12308 (pos_visible_p): Revert the comparison against bottom_y to what it
12309 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12312 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12314 Fix coding-related core dumps with gcc -ftrapv.
12315 The code was computing A - B, where A and B are pointers, and B is
12316 random garbage. This can lead to core dumps on platforms that
12317 have special pointer registers, and it also leads to core dumps on
12318 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12319 A - B only when B is initialized properly.
12320 * coding.c (coding_set_source, coding_set_destination): Return void.
12321 (coding_change_source, coding_change_destinations): New functions,
12322 with the old behaviors of coding_set_source and coding_set_destination.
12323 All callers that need an offset changed to use these new functions.
12325 2012-05-26 Glenn Morris <rgm@gnu.org>
12327 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
12329 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12331 Extend mouse support on W32 text-mode console.
12332 * xdisp.c (draw_row_with_mouse_face):
12333 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12335 * w32console.c: Include window.h.
12336 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12338 (initialize_w32_display): Initialize mouse-highlight data.
12340 * w32inevt.c: Include termchar.h and window.h.
12341 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12342 moves, call note_mouse_highlight. If help_echo changed, call
12343 gen_help_event to produce help-echo message in the echo area.
12344 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12347 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12349 * lread.c (read1): Simplify slightly to avoid an overflow warning
12350 with GCC 4.7.0 on x86-64.
12352 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12354 * bidi.c (bidi_mirror_char): Revert last change: an int is
12355 definitely wide enough here.
12357 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12359 Fix integer width and related bugs (Bug#9874).
12360 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
12361 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
12362 (string_bytes, check_sblock, allocate_string_data):
12363 (compact_small_strings, Fmake_bool_vector, make_string)
12364 (make_unibyte_string, make_multibyte_string)
12365 (make_string_from_bytes, make_specified_string)
12366 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
12367 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
12369 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12370 (allocate_pseudovector):
12371 Use int, not EMACS_INT, where int is wide enough.
12372 (inhibit_garbage_collection, Fgarbage_collect):
12373 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12374 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12375 int might not be wide enough.
12376 (bidi_cache_search, bidi_cache_find, bidi_init_it)
12377 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
12378 (bidi_at_paragraph_end, bidi_find_paragraph_start)
12379 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
12380 (bidi_level_of_next_char, bidi_move_to_visually_next):
12381 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12382 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
12383 (Fkill_buffer, Fset_buffer_major_mode)
12384 (advance_to_char_boundary, Fbuffer_swap_text)
12385 (Fset_buffer_multibyte, overlays_at, overlays_in)
12386 (overlay_touches_p, struct sortvec, record_overlay_string)
12387 (overlay_strings, recenter_overlay_lists)
12388 (adjust_overlays_for_insert, adjust_overlays_for_delete)
12389 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
12390 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
12391 (Foverlay_recenter, last_overlay_modification_hooks_used)
12392 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
12393 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12394 (validate_region): Omit unnecessary test for b <= e,
12395 since that's guaranteed by the previous test.
12396 (adjust_overlays_for_delete): Avoid pos + length overflow.
12397 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12398 (report_overlay_modification):
12399 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12400 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12401 Omit pointer cast, which isn't needed anyway, and doesn't work
12402 after the EMACS_INT -> ptrdiff_t change.
12403 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12404 * buffer.h: Adjust decls to match defn changes elsewhere.
12405 (struct buffer_text, struct buffer):
12406 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12407 Use EMACS_INT, not int, where int might not be wide enough.
12408 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12409 not int, to avoid needless 32-bit limit on 64-bit hosts.
12410 (exec_byte_code): Use tighter memory-full test, one that checks
12411 for alloca overflow. Don't compute the address of the object just
12412 before an array, as that's not portable. Use EMACS_INT, not
12413 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12414 * callint.c (Fcall_interactively):
12415 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12416 * callproc.c (call_process_kill, Fcall_process):
12417 Don't assume pid_t fits into an Emacs fixnum.
12418 (call_process_cleanup, Fcall_process, child_setup):
12419 Don't assume pid_t fits into int.
12420 (call_process_cleanup, Fcall_process, delete_temp_file)

12422 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12423 (Fcall_process): Simplify handling of volatile integers.
12424 Use int, not EMACS_INT, where int will do.
12425 * casefiddle.c (casify_object, casify_region, operate_on_word)
12426 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
12427 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12428 (casify_object): Avoid integer overflow when overallocating buffer.
12429 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12430 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12431 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12432 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12433 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
12434 integers are now checked earlier. All uses replaced with XINT.
12436 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12437 For CCL_MapSingle, check that content and value are in int range.
12438 (ccl_driver, Fregister_code_conversion_map):
12439 Check that Vcode_version_map_vector is a vector.
12440 (resolve_symbol_ccl_program): Check that vector header is in range.
12441 Always copy the vector, so that we can check its contents reliably
12442 now rather than having to recheck each instruction as it's being
12443 executed. Check that vector words fit in 'int'.
12444 (ccl_get_compiled_code, Fregister_ccl_program)
12445 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12446 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12447 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12448 contents are in range.
12449 (Fccl_execute_on_string): Check that status is in range.
12450 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12451 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12452 Accept and return EMACS_INT, not int, because callers can pass values
12453 out of 'int' range.
12454 (c_string_width, strwidth, lisp_string_width, chars_in_text)
12455 (multibyte_chars_in_text, parse_str_as_multibyte)

12458 (string_escape_byte8, Fget_byte):
12459 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12460 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12461 avoid mishandling large integers.
12462 * character.h: Adjust decls to match defn changes elsewhere.
12463 * charset.c (load_charset_map_from_file, find_charsets_in_text)
12464 (Ffind_charset_region):
12465 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12466 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
12467 (load_charset_map_from_vector, Fdefine_charset_internal):
12468 Don't assume fixnum fits in int.
12469 (load_charset_map_from_vector, Fmap_charset_chars):
12470 Remove now-unnecessary CHECK_NATNUMs.
12471 (Fdefine_charset_internal): Check ranges here, more carefully.
12472 Don't rely on undefined behavior with signed left shift overflow.
12473 Don't assume unsigned int fits into fixnum, or that fixnum fits
12474 into unsigned int. Don't require max_code to be a valid fixnum;
12475 that's not true for gb10830 4-byte on a 32-bit host. Allow
12476 invalid_code to be a cons, for the same reason. Require code_offset
12477 to be a character. Avoid int overflow if max_char is close
12479 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12480 this is intended anyway and avoids some undefined behavior.
12481 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12482 INDEX_TO_CODE_POINT, as that's what it expects.
12483 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12484 * charset.h (DECODE_CHAR): Return int, not unsigned;
12485 this is what was intended anyway, and it avoids undefined behavior.
12486 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12487 integer-overflow issues.
12488 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12489 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12490 where the argument is EMACS_INT, and this behavior is not intended.
12491 * chartab.c (Fmake_char_table, Fset_char_table_range)
12492 (uniprop_get_decoder, uniprop_get_encoder):
12493 Don't assume fixnum fits in int.
12494 * cmds.c (move_point): New function, that does the gist of
12495 Fforward_char and Fbackward_char, but does so while checking
12496 for integer overflow more accurately.
12497 (Fforward_char, Fbackward_char): Use it.
12498 (Fforward_line, Fend_of_line, internal_self_insert)
12499 (internal_self_insert):
12500 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12501 Fix a FIXME, by checking for integer overflow when calculating
12502 target_clm and actual_clm.

12534 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12535 (consume_chars): Rewrite to not calculate an address outside buffer.
12536 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
12537 Don't access memory outside of the args array.
12538 (Fdefine_coding_system_internal): Check for charset-id overflow.
12539 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
12540 result of ENCODE_CHAR.
12541 * coding.h: Adjust decls to match defn changes elsewhere.
12542 (struct coding_system):

13238 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
13240 2012-05-19 Ken Brown <kbrown@cornell.edu>
13242 * xfns.c (x_in_use): Remove `static' qualifier.
13243 * xterm.h (x_in_use): Declare.
13244 * xgselect.c: Include xterm.h.
13245 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
13246 and `display_arg' (bug#9754).
13248 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
13250 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
13252 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
13253 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
13255 2012-05-18 Eli Zaretskii <eliz@gnu.org>
13257 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
13259 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
13260 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
13262 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
13263 reference to image_cache->refcount.
13264 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
13266 2012-05-17 Juri Linkov <juri@jurta.org>
13268 * search.c (Fword_search_regexp, Fword_search_backward)
13269 (Fword_search_forward, Fword_search_backward_lax)
13270 (Fword_search_forward_lax): Move functions to isearch.el
13271 (bug#10145, bug#11381).
13273 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13275 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13277 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13279 * lread.c (init_obarray): Declare Qt and Qnil as special.
13281 2012-05-14 Glenn Morris <rgm@gnu.org>
13283 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13284 Put "libexec" before "bin", for the sake of init_callproc_1.
13286 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13288 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13290 * unexaix.c: Port to more-recent AIX compilers.
13291 (report_error, report_error_1, make_hdr, copy_sym)
13292 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13293 Make arguments const char *, not char *, to avoid violations of C
13294 standard and to fix some AIX warnings reported by Gilles Pion.
13296 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13298 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13299 already have overlays loaded.
13300 (handle_single_display_spec): Before returning without displaying
13301 fringe bitmap, synchronize the bidi iterator with the main display
13302 iterator, by calling iterate_out_of_display_property.
13303 (iterate_out_of_display_property): Detect buffer iteration by
13304 testing that it->string is a Lisp string.
13305 (get_next_display_element): When the current object is exhausted,
13306 and there's something on it->stack, call set_iterator_to_next to
13307 proceed with what's on the stack, instead of returning zero.
13308 (set_iterator_to_next): If called at the end of a Lisp string,
13309 proceed to consider_string_end without incrementing string
13310 position. Don't increment display vector index past the end of
13311 the display vector. (Bug#11417)
13312 (pos_visible_p): Don't report a position visible when move_it_to
13313 stopped at the last line of window, which happens to be scanned
13314 backwards by the bidi iteration. (Bug#11464)
13316 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13318 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13319 and right-margin display specs even if the spec is invalid or we
13320 are on a TTY, and thus unable to display on the fringes.
13321 That's because the text with the property will not be displayed anyway,
13322 so we need to signal to the caller that this is a "replacing"
13323 display spec. This fixes display when the spec is invalid or we
13326 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13328 * unexaix.c (make_hdr): Fix typo in prototype.
13329 This bug broke the build on AIX. Problem reported by Gilles Pion.
13331 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13333 * keyboard.c (kbd_buffer_get_event): Read special events also in
13334 batch mode. (Bug#11415)
13336 2012-05-12 Glenn Morris <rgm@gnu.org>
13338 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13340 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13342 * lisp.mk (lisp): Add newcomment.elc.
13344 2012-05-12 Glenn Morris <rgm@gnu.org>
13346 * Makefile.in (MKDIR_P): New, set by configure.
13347 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13349 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13351 Remove unused function hourglass_started.
13352 * dispextern.h (hourglass_started):
13353 * w32fns.c (hourglass_started):
13354 * xdisp.c (hourglass_started): Remove.
13356 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13358 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13359 Update dependencies.
13361 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13363 * xgselect.c (xg_select): Put maxfds+1 into a var.
13364 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13366 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13368 2012-05-10 Dave Abrahams <dave@boostpro.com>
13370 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13371 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13373 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13375 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13376 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13377 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13378 Initialize xd_registered_buses.
13380 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13382 Untag more efficiently if USE_LSB_TAG.
13383 This is based on a proposal by YAMAMOTO Mitsuharu in
13384 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13385 For an admittedly artificial (nth 8000 longlist) benchmark on
13386 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13387 Emacs's overall text size by 1%.
13388 * lisp.h (XUNTAG): New macro.
13389 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13390 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13391 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13392 * eval.c (Fautoload):
13393 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13394 * frame.h (XFRAME): Use XUNTAG.
13396 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13397 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13398 Remove unportable assumptions about print widths of types like
13400 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13401 intptr_t when converting between pointer and integer, to avoid GCC
13402 warnings about wrong width.
13404 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13406 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13407 stack for each reader_thread, instead of defaulting to 8MB
13408 determined by the linker. This avoids failures in creating
13409 subprocesses on Windows 7, see the discussion in this thread:
13410 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13412 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13414 Fix up display of the *Minibuf-0* buffer in the mini window.
13415 * keyboard.c (read_char): Don't clear the echo area if there's no
13417 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13418 contents of *Minibuf-0*) if there's no message displayed in its stead.
13420 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13422 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13425 2012-05-06 Chong Yidong <cyd@gnu.org>
13427 * lisp.mk (lisp): Update.
13429 2012-05-05 Jim Meyering <meyering@redhat.com>
13431 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13433 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13435 * data.c (PUT_ERROR): New macro.
13436 (syms_of_data): Use it. Add new error type `user-error'.
13437 * undo.c (user_error): New function.
13438 (Fprimitive_undo): Use it.
13439 * print.c (print_error_message): Adjust print style for `user-error'.
13440 * keyboard.c (user_error): New function.
13441 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13443 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13445 Do not limit current-time-string to years 1000..9999.
13446 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13447 (Fcurrent_time_string): Support any year that is supported by the
13448 underlying localtime representation. Don't use asctime, as it
13449 has undefined behavior for years outside the range -999..9999.
13451 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13453 Fix race conditions involving setenv, gmtime, localtime, asctime.
13454 Without this fix, interrupts could mess up code that uses these
13455 nonreentrant functions, since setting TZ invalidates existing
13456 tm_zone or tzname values, and since most of these functions return
13457 pointers to static storage.
13458 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13459 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13460 Grow the critical sections to include not just invoking
13461 localtime/gmtime, but also accessing these functions' results
13462 including their tm_zone values if any, and any related TZ setting.
13463 (format_time_string): Last arg is now struct tm *, not struct tm **,
13464 so that the struct tm is saved in the critical section.
13465 All callers changed. Simplify allocation of initial buffer, partly
13466 motivated by the fact that memory allocation needs to be outside
13467 the critical section.
13469 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13471 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13472 with RESET_INTERVAL.
13474 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13475 Remove duplicated buffer name initialization.
13477 2012-05-02 Jim Meyering <jim@meyering.net>
13479 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13481 * xfns.c (x_window): Use xstrdup (Bug#11375).
13483 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13485 * xdisp.c (pos_visible_p): If already at a newline from the
13486 display string before the 'while' loop, don't walk back the glyphs
13487 from it3.glyph_row. Solves assertion violation when the display
13488 string begins with a newline (egg.el). (Bug#11367)
13490 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13492 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13495 2012-05-01 Glenn Morris <rgm@gnu.org>
13497 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13498 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13499 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13500 All were removed before 23.1.
13502 * dispnew.c: Remove HAVE_LIBNCURSES test;
13503 it is always true on relevant platforms.
13505 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13506 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13508 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13510 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13512 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13513 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13516 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13518 Do not avoid creating empty evaporating overlays (Bug#9642).
13519 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13520 That is, do not delete an evaporating overlay if it becomes
13521 empty after its bounds are adjusted to fit within its buffer.
13522 This fix caused other problems, and I'm reverting it until we get
13523 to the bottom of them.
13525 2012-04-27 Chong Yidong <cyd@gnu.org>
13527 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13529 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13531 * xdisp.c (pos_visible_p): If the window start position is beyond
13532 ZV, start the display from buffer beginning. Prevents assertion
13533 violation in init_iterator when the minibuffer window is scrolled
13534 via the scroll bar.
13536 * window.c (window_scroll_pixel_based): Likewise.
13538 2012-04-27 Chong Yidong <cyd@gnu.org>
13540 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13542 2012-04-27 Glenn Morris <rgm@gnu.org>
13544 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13545 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13547 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13549 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13550 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13552 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13554 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13555 display element, check also the underlying string or buffer
13556 character. (Bug#11341)
13558 * w32menu.c: Include w32heap.h.
13559 (add_menu_item): If the call to AppendMenuW (via
13560 unicode_append_menu) fails, disable Unicode menus only if we are
13561 running on Windows 9X/Me.
13563 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13565 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13566 (xgetint): Add missing shift for LSB tags.
13568 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13570 * keyboard.c (read_char): Don't wipe echo area for select window
13571 events: These might get delayed via `mouse-autoselect-window'
13574 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13576 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13577 manipulation of :loaded-from data.
13579 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13581 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13582 now a cons (bug#11311).
13584 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13586 Do not create empty overlays with the evaporate property (Bug#9642).
13587 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13588 if it becomes empty after its bounds are adjusted to fit within
13589 its buffer. Without this fix, in a nonempty buffer (let ((o
13590 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13591 yields an empty overlay that has the evaporate property, which is
13592 not supposed to happen.
13594 Fix minor GTK3 problems found by static checking.
13595 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13596 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13597 (struct _EmacsFixedClass, emacs_fixed_get_type):
13598 Move decls here from emacsgtkfixed.h, since they needn't be public.
13599 (emacs_fixed_get_type): Now static.
13600 (emacs_fixed_class_init): Omit unused local.
13601 (emacs_fixed_child_type): Remove; unused.
13602 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13603 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13604 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13605 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
13606 (EMACS_FIXED_GET_CLASS): Remove; unused.
13607 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
13609 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
13610 Problem reported by Juanma Barranquero for Windows -Wunused-function.
13612 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13614 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13615 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13616 (__malloc_size_t, __malloc_ptrdiff_t):
13617 Remove. All uses removed, replaced by the definiens if needed,
13618 since we can assume C89 or better now.
13619 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

13627 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13628 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13629 Define using prototypes, not old style.
13630 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
13631 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
13632 (align): Don't assume that signed integer overflow wraps around.
13633 Omit unused local var.
13634 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
13635 (_free_internal_nolock, memalign, mallochook, reallochook):
13636 Omit no-longer-needed casts.
13637 (valloc): Use getpagesize, not __getpagesize.
13638 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
13639 (struct hdr): The 'magic' member is now size_t, not unsigned long.
13641 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
13643 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
13645 Move functions from C to Lisp. Make non-blocking method calls
13646 the default. Implement further D-Bus standard interfaces.
13648 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

13664 (xd_signature, xd_append_arg): Allow float for integer types.
13665 (xd_get_connection_references): New function.
13666 (xd_get_connection_address): Rename from xd_initialize.
13667 Return cached address.
13668 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
13669 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp
13671 (Fdbus_init_bus): New optional arg PRIVATE. Cache address.
13672 Return number of refcounts.

13703 2012-04-22 Leo Liu <sdl.web@gmail.com>
13705 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
13707 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13709 * sysdep.c [__FreeBSD__]: Minor cleanups.
13710 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13711 Use Emacs indenting style more consistently. Avoid some casts.

13716 * sysdep.c (list_system_processes, system_process_attributes):
13717 Add implementation for FreeBSD (Bug#5243).

13723 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
13725 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
13726 It is never used otherwise.
13728 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13730 * print.c (print_preprocess): Only check print_depth if print-circle
13732 (print_object): Check for cycles even when print-circle is nil and
13733 print-gensym is t, but only check print_depth if print-circle is nil.
13735 2012-04-20 Chong Yidong <cyd@gnu.org>
13737 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13738 set the status to "failed" and ensure that sentinel is run.
13740 2012-04-20 Glenn Morris <rgm@gnu.org>
13742 * process.c (Fset_process_inherit_coding_system_flag)
13743 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

13771 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
13772 -Wunused-result, -Wunused-variable. This should go away once
13773 the Emacs and Gnulib regex code is merged.
13774 (xmalloc, xrealloc): Now static.
13776 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

13793 New extern decls, to avoid calling undeclared functions.
13794 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13795 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13796 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13797 (NEED_MEM_INSERT): New macro.
13798 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13799 Remove one incorrect comment and fix another.

13814 Remove decls. This fixes an "It stinks!".
13816 * alloc.c (which_symbols): Fix alignment issue / type clash.
13818 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13820 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

13835 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13836 * s/netbsd.h, s/sol2-6.h:
13837 Remove definition of GC_MARK_STACK, since the default now works.
13838 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

13840 no longer the default.
13841 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13843 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

13864 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
13866 2012-04-11 Daniel Colascione <dancol@dancol.org>
13868 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13869 against is gone. It's better to use vfork now so that when Cygwin
13870 gains a new, working vfork, we use it automatically (bug#10398).
13872 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
13874 * window.c (save_window_save): Obey window-point-insertion-type.

13892 * w32.c (w32_delayed_load): Record the full path of the library
13893 being loaded (bug#10424).
13895 2012-04-09 Glenn Morris <rgm@gnu.org>
13897 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13898 not just in the obarray, before snarfing them. (Bug#11036)

13915 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13916 attempts per process (connection).
13918 2012-04-09 Chong Yidong <cyd@gnu.org>
13920 * eval.c (Fuser_variable_p, user_variable_p_eh)

13922 (Fdefvar): Caller changed.
13924 * callint.c (Finteractive, Fcall_interactively):
13925 * minibuf.c (Fread_variable): Callers changed.
13927 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13929 * xdisp.c (set_cursor_from_row): If the display string appears in
13930 the buffer at position that is closer to point than the position
13931 after the display string, display the cursor on the first glyph of
13932 the display string. Fixes cursor display when a 'display' text
13933 property immediately follows invisible text. (Bug#11094)
13935 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13937 composite.c: use 'double' consistently
13938 * composite.c (get_composition_id): Use 'double' consistently
13939 instead of converting 'float' to 'double' and vice versa; this is
13940 easier to understand and avoids a GCC warning.
13942 2012-04-09 Glenn Morris <rgm@gnu.org>
13944 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13945 preparation for dumping it with emacs. (Bug#4789)

13967 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13968 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13969 objects, as mark_maybe_pointer will catch them otherwise.

13987 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13988 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13989 [!WINDOWSNT]: New macros.
13990 (init_libxml2_functions, libxml2_loaded_p): New functions.
13991 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13992 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13993 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13994 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13996 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13997 Call init_libxml2_functions before calling libxml2 functions.
13998 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14000 * emacs.c: Don't include libxml/parser.h.
14001 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14002 xmlCleanupParser directly.

14006 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14008 * indent.c (Fvertical_motion): If there is a display string at
14009 point, use it.vpos to compute how many lines to backtrack after
14010 move_it_to point. (Bug#11133)
14012 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14014 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14015 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14016 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14017 macros related to unification of CJK characters. For the details,
14018 see the discussion following the message here:
14019 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14021 2012-04-04 Chong Yidong <cyd@gnu.org>
14023 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14025 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14027 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

14035 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14037 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14038 position we get to after a call to move_it_to fails the
14039 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14040 only if we wind up in a string from display property. (Bug#11063)
14042 * window.c (Fdelete_other_windows_internal): Invalidate the row
14043 and column information about mouse highlight, so that redisplay
14044 restores it after reallocating the glyph matrices. (Bug#7464)
14046 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14047 string comes from a `display' text property, use the buffer
14048 position of that property as if we actually saw that position in
14050 (move_it_by_lines): Remove the assertion that
14051 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14052 violated when there's a before-string at the beginning of a line.
14055 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14057 * xdisp.c (append_space_for_newline): If the default face was

14059 (extend_face_to_end_of_line): Use the remapped default face for
14060 extending the face to the end of the line.
14061 (display_line): Call extend_face_to_end_of_line when the default
14062 face was remapped. (Bug#11068)
14064 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14066 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
14068 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

14084 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14085 (command_loop_1): Use it; inhibit selection update for

14090 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14092 2012-03-25 Kenichi Handa <handa@m17n.org>
14094 * dispextern.h (struct glyph): Change the bit length of
14095 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14097 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14099 * s/ms-w32.h (tzname): Include time.h before redirecting to

14108 !SYNC_INPUT. (Bug#11080)
14110 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14112 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14113 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14114 when fetching a multibyte character consumes more bytes than
14115 CHAR_BYTES returns, due to unification of CJK characters in
14116 string_char. (Bug#11073)
14118 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14120 * process.c (wait_reading_process_output): Handle pty disconnect
14121 by refraining from sending oneself a SIGCHLD (bug#10933).
14123 2012-03-22 Chong Yidong <cyd@gnu.org>
14125 * dispextern.h (struct it): New member string_from_prefix_prop_p.

14144 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
14145 to reflect default non-nil value of redisplay-dont-pause.
14147 2012-03-19 Kenichi Handa <handa@m17n.org>
14149 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
14150 it fit in a valid range (Bug#11003).
14152 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14154 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14155 that is not from display property, accept the row as a "cursor
14156 row" if one of the string's character has a non-nil `cursor'
14157 property. Fixes cursor positioning when there are newlines in
14158 overlay strings, e.g. in icomplete.el. (Bug#11035)
14160 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

14194 2012-03-03 Glenn Morris <rgm@gnu.org>
14196 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14198 2012-03-02 Eli Zaretskii <eliz@gnu.org>

14211 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14213 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14214 push_it before setting up the iterator for the first overlay
14215 string, even if we have an empty string loaded.
14216 (next_overlay_string): If there's an empty string on the iterator
14217 stack, pop the stack. (Bug#10903)
14219 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14221 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14222 Suggested by Stefan Monnier in
14223 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14224 * alloc.c (widen_to_Lisp_Object): New static function.
14225 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14226 and widening them to Lisp_Objects. This would work even if
14227 USE_LSB_TAG is defined and wide integers are used, which might
14228 happen in a future version of Emacs.
14230 2012-02-25 Chong Yidong <cyd@gnu.org>
14232 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

14237 before saving to clipboard manager.
14239 2012-02-24 Chong Yidong <cyd@gnu.org>
14241 * keyboard.c (process_special_events): Handle all X selection
14242 requests in kbd_buffer, not just the next one (Bug#8869).
14244 2012-02-23 Chong Yidong <cyd@gnu.org>
14246 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14247 call when setting menu-bar-lines and tool-bar-lines parameters.
14248 (unwind_create_frame_1): New helper function.
14250 * window.c (inhibit_window_configuration_change_hook): New var.

14269 when computing $valmask.
14271 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14272 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14273 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14274 It's useless in that case, and it can cause problems on hosts
14275 that allocate halves of EMACS_INT values separately.
14276 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14277 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14278 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14279 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14280 it avoids undefined behavior on hosts where shifting right by more
14281 than the word width has undefined behavior.
14283 2012-02-19 Chong Yidong <cyd@gnu.org>
14285 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14286 (Funhandled_file_name_directory, Ffile_name_as_directory)
14287 (Fdirectory_file_name, Fexpand_file_name)
14288 (Fsubstitute_in_file_name): Protect against invalid file handler
14289 return values (Bug#10845).

14303 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14305 2012-02-15 Chong Yidong <cyd@gnu.org>
14307 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14308 marked as special. Also, starting docstrings with * is obsolete.

14323 2012-02-12 Chong Yidong <cyd@gnu.org>
14325 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14326 as that creates a dangerous corner case.
14328 * window.c (Fdelete_window_internal): Invalidate the mouse
14329 highlight (Bug#9904).
14331 2012-02-12 Glenn Morris <rgm@gnu.org>

14336 * nsselect.m (Fx_own_selection_internal)
14337 (Fx_disown_selection_internal, Fx_selection_exists_p)
14338 (Fx_selection_owner_p, Fx_get_selection_internal):
14339 Sync docs and argument specs with the xselect.c versions.
14341 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

14361 2012-02-07 Chong Yidong <cyd@gnu.org>
14363 * buffer.c (Fbuffer_local_variables)
14364 (buffer_lisp_local_variables): Handle unbound vars correctly;
14365 don't let Qunbound leak into Lisp.
14367 2012-02-07 Glenn Morris <rgm@gnu.org>
14369 * image.c (Fimagemagick_types): Doc fix.
14371 * image.c (imagemagick-render-type): Change it from a lisp object
14372 to an integer. Move the doc here from the lisp manual.

14389 2012-02-04 Eli Zaretskii <eliz@gnu.org>
14391 * w32.c (get_emacs_configuration_options):
14392 Include --enable-checking, if specified, in the return value.

14402 before BEGV. (Bug#10696)
14404 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
14406 Handle overflow when computing char display width (Bug#9496).
14407 * character.c (char_width): Return EMACS_INT, not int.
14408 (char_width, c_string_width): Check for overflow when
14409 computing the width; this is possible now that individual
14410 characters can have unbounded width. Problem introduced
14411 by merge from Emacs 23 on 2012-01-19.

14435 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
14437 (x_produce_glyphs): If the component of a composition is a null
14438 string, set it->pixel_width to 1 to avoid zero-width glyph.

14442 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
14443 first 2 arguments are identical. This makes inserting large
14444 output from a subprocess an order of magnitude faster on
14445 MS-Windows, where all sbrk'ed memory is always contiguous.
14447 2012-01-31 Glenn Morris <rgm@gnu.org>

14542 2012-01-09 Eli Zaretskii <eliz@gnu.org>
14544 * xdisp.c (rows_from_pos_range): Accept additional argument
14545 DISP_STRING, and accept any glyph in a row whose object is that
14546 string as eligible for mouse highlight. Fixes mouse highlight of
14547 display strings from overlays. (Bug#10464)
14549 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
14551 emacs: fix an auto-save permissions race condition (Bug#10400)
14552 * fileio.c (auto_saving_dir_umask): New static var.
14553 (Fmake_directory_internal): Use it.
14554 (do_auto_save_make_dir): Set it, instead of invoking chmod after

14556 too-generous permissions to the directory.
14557 (do_auto_save_eh): Clear it.
14558 (Fdo_auto_save): Catch all errors, not just file errors, so
14559 that the var is always cleared.

14616 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
14617 property that ends at ZV, so that the bidi iteration could be

14898 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
14899 verifies glyph row's hash code--we have just reallocated the

15061 Otherwise, valgrind does not work on some platforms.
15062 Problem reported by Andreas Schwab in
15063 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
15064 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15065 is set, removing the need for VIRT_ADDRESS_VARIES.
15066 (PURE_P): Use a more-efficient implementation that needs just one

15068 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
15069 to 4 (xorl, subq, cmpq, setbe).
15070 * alloc.c (pure): Always extern now, since that's the
15071 VIRT_ADDR_VARIES behavior.
15072 (PURE_POINTER_P): Use a single comparison, not two, for
15073 consistency with the new puresize.h.
15074 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

15541 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
15542 <oslsachem@gmail.com> for helping to debug this.
15544 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
15545 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
15546 (g_b_init_get_glyph_outline_w): New static variables.
15547 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
15548 (GetGlyphOutlineW_Proc): New typedefs.
15549 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
15550 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
15552 (w32font_open_internal, compute_metrics):
15553 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15554 instead of calling the "wide" APIs directly.
15556 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
15558 * w32.h (syms_of_w32font): Add prototype.
15560 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15562 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
15563 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
15564 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
15565 (Fmove_to_window_line): Doc fix.
15567 2011-10-27 Chong Yidong <cyd@gnu.org>
15569 * process.c (make_process): Set gnutls_state to NULL.
15571 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15572 non-NULL, regardless of GNUTLS_INITSTAGE.
15573 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
15574 an error. Set process slots as soon as we allocate them.
15576 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
15578 2011-10-27 Chong Yidong <cyd@gnu.org>
15580 * gnutls.c (emacs_gnutls_deinit): New function.
15581 Deallocate credentials structures as well as calling gnutls_deinit.
15582 (Fgnutls_deinit, Fgnutls_boot): Use it.
15584 * process.c (make_process): Initialize GnuTLS credentials to NULL.
15585 (deactivate_process): Call emacs_gnutls_deinit.
15587 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15589 * image.c (x_create_x_image_and_pixmap):
15590 * w32.c (sys_rename, w32_delayed_load):
15591 * w32font.c (fill_in_logfont):
15592 * w32reg.c (x_get_string_resource): Silence compiler warnings.
15594 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
15596 * w32fns.c (w32_default_color_map): New function,
15597 extracted from Fw32_default_color_map.
15598 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
15600 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
15602 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
15604 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
15606 * keyboard.c (test_undefined): New function (bug#9751).
15607 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
15609 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
15611 * sysdep.c (init_sys_modes): Fix the check for the controlling
15612 terminal (Bug#6649).
15614 2011-10-20 Eli Zaretskii <eliz@gnu.org>
15616 * dispextern.h (struct bidi_it): New member next_en_type.
15618 * bidi.c (bidi_line_init): Initialize the next_en_type member.
15619 (bidi_resolve_explicit_1): When next_en_pos is valid for the
15620 current character, check also for next_en_type being WEAK_EN.
15621 (bidi_resolve_weak): Don't enter the expensive loop if the current
15622 position is before next_en_pos. Record the bidi type of the first
15623 non-ET, non-BN character we find, in addition to its position.
15624 (bidi_level_of_next_char): Invalidate next_en_type when
15625 next_en_pos is over-stepped.
15627 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15629 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15630 * editfns.c: Rewrite current-time-zone so that it invokes
15631 the equivalent of (format-time-string "%Z") to get the time zone name.
15632 This fixes a bug when the time zone name contains characters that
15633 need converting from the system time locale to Emacs internal format.
15634 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15635 that patch fixed format-time-string to do the conversion, but
15636 I forgot to fix current-time-zone.
15637 (format_time_string): New function, containing most of
15638 what Fformat_time_string used to contain.
15639 (Fformat_time_string): Rewrite in terms of format_time_string.
15640 This doesn't change this function's behavior.
15641 (current-time-zone): Rewrite to use format_time_string.
15642 This fixes the bug reported by Michael Schierl in
15643 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15644 Jason Rumney's 2007-06-07 change worked around this bug, but
15646 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15648 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15650 * xdisp.c (start_display): If the character at POS is displayed
15651 via a display vector, reset IT->current.dpvec_index to zero.
15652 (try_window_reusing_current_matrix): If a line ends in a display
15653 vector or the next line starts in a display vector, continue
15654 redrawing the window even though the character position of
15655 start_row was reached.
15658 2011-10-18 Chong Yidong <cyd@gnu.org>
15660 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15661 with nobreak-char-display too.
15663 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15665 Fix part 3 of bug#9771.
15666 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15667 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15668 non-neutral characters if the current character is a paragraph
15669 separator (a.k.a. Newline). This avoids running the same
15670 expensive loop twice, once when we consume the preceding newline
15671 and the other time when the line actually needs to be displayed.
15672 Avoid the loop when we see neutrals on the base embedding level
15673 following a character whose directionality is the same as the
15674 paragraph's. This avoids running the expensive loop when a line
15675 ends in a long sequence of neutrals, like control characters.
15676 Add assertion against STRONG_AL type. Slightly rearrange code
15677 that determines the type of a neutral given the first non-neutral
15679 (bidi_level_of_next_char): Set next_en_pos to zero when
15680 invalidating its info.
15682 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15684 * xdisp.c (push_display_prop): Determine whether to record string
15685 or buffer position by IT->string, not by IT->method. Allow
15686 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15687 (move_it_vertically_backward): Don't look for character position
15688 immediately after the newline when in a continuation line.
15691 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15693 * window.c (coordinates_in_window): Rewrite and delabelize
15694 vertical border check. (Bug#5357) (Bug#9618)
15696 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15698 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15699 errors in XSetWindowBorder (bug#9310).
15701 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15703 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15704 avoid crash when xmalloc overrun checking is enabled.
15706 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15708 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15709 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15710 cursor motion with <left> and <right> arrow keys.
15712 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15713 some callers set that themselves.
15715 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15717 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15718 display string and the previous row comes from the same string and
15719 is empty. (Bug#9739) (Bug#9738)
15721 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15723 * doc.c (get_doc_string): Encode file name (bug#9735).
15725 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15727 * bidi.c (bidi_level_of_next_char):
15728 * xdisp.c (get_visually_first_element): Remove old incorrect
15729 comments regarding the Unicode Line Separator character.
15731 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15733 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15735 * alloc.c (Fgc_status): Do not access beyond zombies array
15736 boundary if nzombies > MAX_ZOMBIES.
15737 * alloc.c (dump_zombies): Add missing format specifier.
15739 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15741 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15742 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15744 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15745 Some packages use them to denote characters with modifiers.
15747 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15749 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15750 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15751 matching a pp-number. Rename parameter var to var1.
15753 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15755 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15757 2011-10-08 Glenn Morris <rgm@gnu.org>
15759 * callint.c (Fcall_interactively): Give a more explicit error for the
15760 'c' case with a non-character input. (Bug#8479)
15762 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15764 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15766 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15767 lines that are hscrolled on the left.
15769 * dispnew.c (buffer_posn_from_coords): Account for a possible
15770 presence of header-line. (Bug#4426)
15772 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15774 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15775 Don't advertise functionality which we discourage or doesn't work.
15777 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15779 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15780 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15781 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15782 this makes Emacs dump core during garbage collection on rare
15783 occasions. sizeof is obviously inferior to offsetof here, so
15784 stick with offsetof.
15785 (GC_POINTER_ALIGNMENT): New macro.
15786 (mark_memory): Omit 3rd (offset) arg; caller changed.
15787 Don't assume EMACS_INT alignment is the same as pointer alignment.
15789 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15791 * keyboard.c (read_key_sequence_remapped): New var.
15792 (read_key_sequence): Compute remapping in the right buffer.
15793 (command_loop_1): Use read_key_sequence's remapping directly.
15795 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15797 * dired.c (file_name_completion): Don't expand file name.
15798 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15799 before checking file name handler.
15801 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15802 they've been requested explicitly (bug#9591).
15804 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15806 * keymap.c (Fsingle_key_description): Use make_specified_string
15807 instead of build_string to build string from push_key_description.
15810 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15812 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15813 This fixes a Y2038 bug on 64-bit hosts.
15814 * buffer.c (reset_buffer):
15815 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15816 (Fclear_buffer_auto_save_failure):
15817 Use 0, not -1, to represent an unset failure time, since time_t
15818 might not be signed.
15820 Remove dependency on glibc malloc internals.
15821 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15822 Move back here from lisp.h, but with their new implementations.
15823 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15824 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15825 * charset.c (charset_table_init): New static var.
15826 (syms_of_charset): Use it instead of xmalloc. This removes a
15827 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15828 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15829 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15830 Move back to alloc.c.
15831 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15832 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15834 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15836 * nsterm.m (windowDidResize): Call x_set_window_size only when
15837 ns_in_resize is true. Otherwise set pixelwidth/height and
15838 call change_frame_size (Bug#9628).
15840 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15842 Port --enable-checking=all to Fedora 14 x86-64.
15843 * charset.c (syms_of_charset): Also account for glibc malloc's
15844 internal overhead when calculating the initial malloc maximum.
15846 Port --enable-checking=all to Fedora 14 x86.
15847 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15849 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15850 (overrun_check_realloc, overrun_check_free):
15851 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15852 That way, xmalloc returns a properly-aligned pointer even if
15853 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15854 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15855 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15856 into account when calculating the initial malloc maximum.
15857 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15858 Move here from alloc.c, so that charset.c can use it too.
15859 Properly align; the old code wasn't right for common 32-bit hosts
15860 when configured with --enable-checking=all.
15861 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15862 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15864 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15866 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15869 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15871 * xdisp.c (compute_display_string_end): If there's no display
15872 string at CHARPOS, return -1.
15874 * bidi.c (bidi_fetch_char): When compute_display_string_end
15875 returns a negative value, treat the character as a normal
15876 character not covered by a display string. (Bug#9624)
15878 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15880 * lread.c (Fread_from_string): Fix typo in docstring.
15882 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15884 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15885 newline, reseat the iterator instead of bidi-iterating there one
15886 character at a time. (Bug#9610)
15887 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15888 TO_CHARPOS if the bidi iterator is at base embedding level.
15890 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15892 * lread.c (readevalloop): Use correct code for NBSP.
15893 (read1): Likewise. (Bug#9608)
15895 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15897 * dbusbind.c (Fdbus_register_signal): When service is not
15898 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15900 2011-09-25 Glenn Morris <rgm@gnu.org>
15902 * buffer.c (truncate-lines): Doc fix.
15904 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15906 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15907 (Fset_window_next_buffers): Doc fix.
15909 2011-09-24 Glenn Morris <rgm@gnu.org>
15911 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15913 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15915 Fix minor problems found by static checking.
15916 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15917 * indent.c (Fvertical_motion): Fix == vs = typo.
15919 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15921 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15922 Default value is now t. Doc fix.
15924 * indent.c (Fvertical_motion): Compute and apply the overshoot
15925 logic when moving up, not only when moving down. Fix the
15926 confusing name and values of the it_overshoot_expected variable;
15927 logic changes accordingly. (Bug#9254) (Bug#9549)
15929 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15930 CHARPOS is covered by a display string which includes newlines.
15931 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15932 is covered by a display string with embedded newlines.
15934 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15936 * dbusbind.c (Fdbus_register_signal): Add match rule to
15937 Vdbus_registered_objects_table. (Bug#9581)
15938 (Fdbus_register_method, Vdbus_registered_objects_table):
15941 2011-09-24 Jim Meyering <meyering@redhat.com>
15943 do not ignore write error for any output size
15944 The previous change was incomplete.
15945 While it makes emacs --batch detect the vast majority of stdout
15946 write failures, errors were still ignored whenever the output size is
15947 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15948 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15949 && echo FAIL: ignored write error
15950 FAIL: ignored write error
15951 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15952 && echo FAIL: ignored write error
15953 FAIL: ignored write error
15954 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15956 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15958 * emacs.c (Fkill_emacs): In noninteractive mode exit
15959 non-successfully if a write error occurred on stdout. (Bug#9574)
15961 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15963 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15966 * dispextern.h (struct it): Update the comment documenting what
15969 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15971 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15972 a display string, extend search for cursor position to end of row.
15973 (find_row_edges): If the row ends in a newline from a display
15974 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15975 Handle the case of a display string with multiple newlines.
15976 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15977 non-empty line. Fixes confusing cursor motion with arrow keys at
15978 the beginning of a line that starts with whitespace.
15980 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>

15985 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15987 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15988 boolean (Bug#9154).
15990 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15992 * xdisp.c (display_line): Record maximum and minimum buffer
15993 positions even if no glyphs were produced (e.g., by a zero-width
15994 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15995 buffer positions that will be removed from the glyph row because
15997 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15998 column is beyond frame width: don't subtract 1 "pixel" when
15999 computing width of the stretch.
16000 (reseat_at_next_visible_line_start): Undo the change made on
16001 2011-09-17 that saved paragraph information and restored it after
16002 the call to `reseat'. (Bug#9545)
16004 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16006 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16007 and turn window cursor on if cleared (Bug#9415).
16009 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16011 * search.c (boyer_moore): Take unibyte characters from pattern
16012 literally. (Bug#9458)

16018 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16020 Fix minor problem found by static checking.
16021 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16022 initialized, to pacify gcc -Wuninitialized.
16024 * fileio.c: Report proper errno when syscall falls.
16025 (Finsert_file_contents): Save and restore errno,
16026 so that report_file_error outputs the correct diagnostic.
16027 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16029 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16031 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16033 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16035 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16036 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16038 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16040 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16041 about the current paragraph and restore it after the call to reseat.
16043 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16044 (bidi_find_paragraph_start): Search back for paragraph beginning
16045 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16046 (bidi_move_to_visually_next): Only trigger paragraph-related
16047 computations when the last character is a newline or at EOB, not
16048 just any NEUTRAL_B. (Bug#9470)
16050 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16051 truncated lines if point is covered by a display string. (Bug#9524)
16053 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16055 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16056 (cons_to_x_long): New function.
16057 (lisp_data_to_selection_data): Use it. Correct the test for
16058 short-versus-long data; it was negated. Break out of vector
16059 loop, for efficiency, when a long datum is discovered.
16061 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16063 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16065 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16067 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16068 GCC PR/17406) by declaring this function with external scope.
16070 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16072 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16073 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16075 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16077 * editfns.c (Fformat): Correctly handle text properties on "%%".

16083 * term.c (encode_terminal_code):
16084 * composite.c (composition_update_it, get_composition_id):
16085 * xdisp.c (get_next_display_element)
16086 (fill_composite_glyph_string): Add comments about special meaning
16087 of TAB characters in a composition.
16089 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16091 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16092 This occurs when processing a multibyte format.
16093 Problem reported by Wolfgang Jenker.
16095 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16097 * xdisp.c (try_cursor_movement): Only check for exact match if
16098 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16100 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16102 Remove unused external symbols.
16103 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16104 * xdisp.c (calc_pixel_width_or_height): Now static.
16105 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16106 * indent.c (check_display_width):
16107 * w32term.c: Fix comment to match code.
16108 * xterm.c, xterm.h (x_catching_errors): Remove.
16110 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16112 * xselect.c: Use signed conversions more consistently (Bug#9498).
16113 (selection_data_to_lisp_data): Assume incoming selection data are
16114 signed integers, not unsigned. This is to be consistent with
16115 outgoing selection data, which was modified to use signed integers
16116 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16117 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16118 expects long, not unsigned long.
16120 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16122 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16123 computation of loop end. Reported by Johan Bockgård
16126 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16128 * frame.c (Fother_visible_frames_p): Function deleted.
16130 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16132 * indent.c (compute_motion): Process display vector front to back
16133 rather than the other way around. (Bug#2496)
16135 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16137 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16139 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16141 * minibuf.c (Fread_from_minibuffer): Doc fix.
16143 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16145 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16146 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16148 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16150 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16151 value for non-existent files.
16153 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16155 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16156 set its "size" to -1. This will set the modtime_size field of
16157 the corresponding buffer to -1, which is what
16158 verify-visited-file-modtime expects for files that do not exist.
16161 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16163 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16165 * lisp.h: ... from here. push_key_description is no longer
16166 defined in keyboard.c, so its declaration should not be in
16167 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16168 logically belongs with push_key_description.
16170 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16172 * buffer.h: Include <sys/types.h> instead of <time.h>.
16173 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16174 Problem reported by Herbert J. Skuhra.
16176 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16178 * xml.c (parse_region): Make the parsing work for
16179 non-comment-starting XML files again (bug#9144).
16181 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16183 * image.c (gif_load): Fix calculation of bottom and right corner.
16186 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16188 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16189 redisplay in small windows.
16191 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16193 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16195 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16197 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16198 Operate on live windows only.
16200 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16202 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16204 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16206 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16207 only under bidi iteration.
16209 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16211 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16213 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16215 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16216 Without this fix, the command to link temacs failed due to an
16217 undefined symbol __builtin_isnan. This is because
16218 /usr/include/iso/math_c99.h #defines isnan(x) to
16219 __builtin_isnan(x), but the bundled gcc, which identifies itself
16220 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16222 * floatfns.c (isnan): #undef, and then #define to a clone of
16224 (Fisnan): Always define, since it's always available now.
16225 (syms_of_floatfns): Always define isnan at the Lisp level.
16227 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16229 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16231 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16233 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16234 The previous code assumed that file offsets (off_t values) fit in
16235 EMACS_INT variables, which is not true on typical 32-bit hosts.
16236 The code messed up by falsely reporting buffer overflow in cases
16237 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16238 when "big" contains more than 2**29 bytes, even though this
16239 inserts just one byte and does not overflow the buffer.
16240 (Finsert_file_contents): Store file offsets as off_t
16241 values, not as EMACS_INT values. Check for overflow when
16242 converting between EMACS_INT and off_t. When checking for
16243 buffer overflow or for overlap, take the offsets into account.
16244 Don't use EMACS_INT for small values where int suffices.
16245 When checking for overlap, fix a typo: ZV was used where
16246 ZV_BYTE was intended.
16247 (Fwrite_region): Don't assume off_t fits into 'long'.
16248 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16250 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16252 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16254 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16256 sprintf-related integer and memory overflow issues (Bug#9412).
16258 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16259 (esprintf, exprintf, evxprintf): New functions.
16260 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16261 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16262 (modify_event_symbol): Do not assume that the length of
16263 name_alist_or_stem is safe to alloca and fits in int.
16264 (Fexecute_extended_command): Likewise for function name and binding.
16265 (Frecursion_depth): Wrap around reliably on integer overflow.
16266 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16267 since some callers pass EMACS_INT values.
16268 (Fsingle_key_description): Don't crash if symbol name contains more
16269 than MAX_ALLOCA bytes.
16270 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16271 (get_minibuffer): Arg is now EMACS_INT, not int.
16272 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16273 (esprintf, exprintf, evxprintf): New decls.
16274 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16276 * dbusbind.c (signature_cat): New function.
16277 (xd_signature, Fdbus_register_signal):
16278 Do not overrun buffer; instead, report string overflow.
16280 * dispnew.c (add_window_display_history): Don't overrun buffer.
16281 Truncate instead; this is OK since it's just a log.
16283 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16284 even if the time zone offset is outlandishly large.
16285 Don't mishandle offset == INT_MIN.
16287 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16288 when creating daemon; the previous buffer-overflow check was incorrect.
16290 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16291 which has the guts of the old verror function.
16293 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16294 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16296 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16297 (font_unparse_xlfd): Don't blindly alloca long strings.
16298 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16299 fits in int, when using sprintf. Use single snprintf to count
16300 length of string rather than counting it via multiple sprintfs;
16301 that's simpler and more reliable.
16302 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16303 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16304 sprintf, in case result does not fit in int.
16306 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16307 (fontset_from_font): Print it.
16309 * frame.c (tty_frame_count): Now printmax_t, not int.
16310 (make_terminal_frame, set_term_frame_name): Print it.
16311 (x_report_frame_params): In X, window IDs are unsigned long,
16312 not signed long, so print them as unsigned.
16313 (validate_x_resource_name): Check for implausibly long names,
16314 and don't assume name length fits in 'int'.
16315 (x_get_resource_string): Don't blindly alloca invocation name;
16316 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16319 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16320 (xg_check_special_colors, xg_set_geometry):
16321 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16323 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16324 Use esprintf, not sprintf, in case result does not fit in int.
16326 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16327 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16328 it as a large positive number.
16329 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16330 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16332 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16333 in case result does not fit in int.
16335 * print.c (float_to_string): Detect width overflow more reliably.
16336 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16337 buffer overrun. Don't assume list length fits in 'int'. Treat
16338 print length of 0 as 0, not as infinity; to be consistent with other
16339 uses of print length in this function. Don't overflow print length
16340 index. Don't assume hash table size fits in 'long', or that
16341 vectorlike size fits in 'unsigned long'.
16343 * process.c (make_process): Use printmax_t, not int, to format
16344 process-name gensyms.
16346 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16348 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16349 to avoid potential buffer overrun.
16351 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16352 if X resource line is longer than 512 bytes.
16354 * xfns.c (x_window): Make sprintf buffer a bit bigger
16355 to avoid potential buffer overrun.
16357 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16359 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16361 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16363 Integer overflow fixes for scrolling, etc.
16364 Without these, Emacs silently mishandles large integers sometimes.
16365 For example, "C-u 4294967297 M-x recenter" was treated as if
16366 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16368 * xdisp.c (try_window_id): Check Emacs fixnum range before
16369 converting to 'int'.
16371 * window.c (window_scroll_line_based, Frecenter):
16372 Check that an Emacs fixnum is in range before assigning it to 'int'.
16373 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16374 values converted from Emacs fixnums.
16375 (Frecenter): Don't wrap around a line count if it is out of 'int'
16376 range; instead, treat it as an extreme value.
16377 (Fset_window_configuration, compare_window_configurations):
16378 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16380 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16381 that can exceed INT_MAX. Check that EMACS_INT value is in range
16382 before assigning it to the (possibly-narrower) index.
16383 (match_limit): Don't assume that a fixnum can fit in 'int'.
16385 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16388 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16389 (Fvertical_motion): Don't wrap around LINES values that don't fit
16390 in 'int'. Instead, treat them as extreme values. This is good
16391 enough for windows, which can't have more than INT_MAX lines anyway.
16393 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16395 * Require libxml/parser.h to avoid compilation warning.
16397 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16399 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16400 since this reportedly can destroy thread storage.
16402 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16404 * syntax.c (find_defun_start): Update all cache variables if
16405 exiting early (Bug#9401).
16407 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16409 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16411 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16412 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16413 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16415 * term.c (tty_append_glyph): New function.
16416 (produce_stretch_glyph): Static function and its prototype deleted.
16418 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16421 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16423 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16424 when checking :margin (Bug#9390).
16425 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16426 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16427 so that the name doesn't mislead. All uses changed.
16429 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16431 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16434 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16436 * xdisp.c (move_it_to): Don't bail out early when reaching
16437 position beyond to_charpos, if we are scanning backwards.
16438 (move_it_vertically_backward): When DY == 0, make sure we get to
16439 the first character in the line after the newline.
16441 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16443 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16444 (ccl_driver): Do not generate an out-of-range pointer.
16445 (Fccl_execute_on_string): Remove unnecessary check for
16446 integer overflow, noted by Stefan Monnier in
16447 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16448 Remove a FIXME that didn't need fixing.
16449 Simplify the newly-introduced buffer reallocation code.
16451 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16453 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16455 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16457 Integer and memory overflow issues (Bug#9196).
16459 * doc.c (get_doc_string): Rework so that
16460 get_doc_string_buffer_size is the actual buffer size, rather than
16461 being 1 less than the actual buffer size; this makes xpalloc more
16464 * image.c (x_allocate_bitmap_record, cache_image):
16465 * xselect.c (Fx_register_dnd_atom):
16466 Simplify previous changes by using xpalloc.
16468 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16469 since either will do and ptrdiff_t is convenient with xpalloc.
16471 * charset.c (charset_table_size)
16472 (struct charset_sort_data.priority): Now ptrdiff_t.
16473 (charset_compare): Don't overflow if priorities differ greatly.
16474 (Fsort_charsets): Don't assume list length fits in int.
16475 Check for size-calculation overflow when allocating sort data.
16476 (syms_of_charset): Allocate an initial charset table that is
16477 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16479 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16481 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16482 The actual value is always <= INT_MAX, and leaving it unsigned made
16483 overflow checking harder.
16485 * dispextern.h (struct glyph_matrix.rows_allocated)
16486 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16487 with xpalloc. The values are still always <= INT_MAX.
16489 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16491 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16492 (SAFE_NALLOCA): New macro.
16494 * region-cache.c (struct boundary.pos, find_cache_boundary)
16495 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16496 (set_cache_region, invalidate_region_cache)
16497 (revalidate_region_cache, know_region_cache, region_cache_forward)
16498 (region_cache_backward, pp_cache):
16499 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16500 so that ptrdiff_t * can be passed to xpalloc.
16501 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16502 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16503 (pp_cache): Don't assume cache_len fits in int.
16504 * region-cache.h: Adjust extern decls to match.
16506 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16507 EMACS_INT, since either will do, for xpalloc.
16509 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16510 (xnmalloc, xnrealloc, xpalloc): New functions.
16512 * bidi.c (bidi_shelve_header_size): New constant.
16513 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16514 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16516 * bidi.c (bidi_cache_shrink):
16517 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16519 Don't update size of array until after memory allocation succeeds,
16520 because xmalloc/xrealloc may not return.
16521 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16522 now that we have proper integer overflow checking.
16523 (record_overlay_string, overlay_strings): Catch overflows when
16524 calculating size of overlay_str_buf.
16526 * callproc.c (Fcall_process): Check for size overflow when
16527 calculating size of args2.
16528 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16529 Normally we prefer signed values, but sticking with ptrdiff_t would
16530 require adding more-complicated checks.
16532 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16533 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16534 Redo buffer-overflow calculations to avoid integer overflow.
16535 Add a FIXME comment where memory seems to be over-allocated.
16537 * character.c (Fstring): Check for size-calculation overflow.
16539 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16540 unnecessary integer overflow. Check for size overflow.
16541 (encode_coding_object): Don't update size until xmalloc succeeds.
16543 * composite.c (get_composition_id): Check for overflow in glyph
16544 length calculations.
16546 Integer and memory overflow fixes for display code.
16547 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16548 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16549 (scrolling_window): Check for overflow in size calculations.

16554 (scrolling_window): Avoid overflow in size calculations.
16555 Don't update size until allocation succeeds.
16556 * fns.c (concat): Check for overflow in size calculations.
16557 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16558 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

16561 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16562 (get_doc_string): Check for size calculation overflow.
16563 Don't update size until allocation succeeds.
16564 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16565 EMACS_INT, where ptrdiff_t will do.
16566 (Fsubstitute_command_keys): Check for string overflow.
16568 * editfns.c (set_time_zone_rule): Don't assume environment length
16570 (message_length): Now ptrdiff_t, not int.
16571 (Fmessage_box): Don't update size until allocation succeeds.
16572 Don't assume message length fits in int.
16573 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16575 * emacs.c (main): Do not reallocate argv, since there is a null at
16576 the end that can be overwritten, and this way there's no need to
16577 worry about size-calculation overflow.
16578 (sort_args): Check for size-calculation overflow.
16580 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16582 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16584 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16585 (x_set_scroll_bar_width, x_figure_window_size):
16586 Check for integer overflow.
16587 (x_set_alpha): Do not assume XINT fits in int.
16589 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16590 This is for the members text_lines, text_cols, total_lines, total_cols,
16591 where the system imposes an 'int' limit.
16593 * fringe.c (Fdefine_fringe_bitmap):
16594 Don't update size until alloc works.
16596 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16597 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16599 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16600 Check for size-calculation overflow.
16601 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16602 do, as we prefer signed integers.
16603 (id_to_widget.max_size, id_to_widget.used)
16604 (xg_store_widget_in_map, xg_remove_widget_from_map)
16605 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16606 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16607 Use and return ptrdiff_t, not int.
16608 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16609 * gtkutil.h: Change prototypes to match the above.
16611 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16612 are duplicate now that they've been promoted to lisp.h.
16613 (x_allocate_bitmap_record, x_alloc_image_color)
16614 (make_image_cache, cache_image, xpm_load):
16615 Don't update size until alloc is done.

16626 Use ptrdiff_t, not int, to count maps.
16627 (read_char_minibuf_menu_prompt): Check for overflow in size
16628 calculations. Don't update size until allocation succeeds.
16629 Redo calculations to avoid overflow.
16630 * keyboard.h: Change prototypes to match the above.
16632 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
16634 (current_minor_maps): Check for size calculation overflow.
16635 * keymap.h: Change prototypes to match the above.
16637 * lread.c (read1, init_obarray): Don't update size until alloc done.
16639 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

16643 Now ptrdiff_t, not int.
16644 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

16658 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16659 for command line length. Do not attempt to address one before the
16660 beginning of an array, as that's not portable.
16662 * term.c (max_frame_lines): Remove; unused.
16663 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
16665 (encode_terminal_code, calculate_costs): Check for size
16666 calculation overflow.

16670 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
16672 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
16673 subtracting pointers.
16674 (gobble_line): Check for overflow more carefully. Don't update size
16677 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
16678 Don't update size until alloc done.
16679 Redo size calculations to avoid overflow.

16688 Use ptrdiff_t, not int, for sizes.
16689 (Finternal_make_lisp_face, cache_face):
16690 Check for size calculation overflow.
16691 (cache_face): Treat size calculation overflows as if they were
16692 memory exhaustion (the usual treatment), rather than aborting.
16694 * xfns.c (x_encode_text, x_set_name_internal)
16695 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16696 sizes, since they can exceed INT_MAX in size. Check for size
16697 calculation overflow.
16699 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16700 (xg_select): Check for size calculation overflow.
16701 Don't update size until alloc done.
16703 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16704 as sprintf is limited to int lengths.
16706 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16707 (X_LONG_MIN): New macros.
16708 Use them to make the following changes clearer.
16709 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16710 This change doesn't affect the value now, but it may help remind
16711 future maintainers not to raise the value too much later.
16712 (SELECTION_QUANTUM): Remove, replacing with ...
16713 (selection_quantum): ... new function, which avoids overflow.
16715 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16716 assumption that selection length fits in 'int'.
16717 (x_reply_selection_request, x_handle_selection_request)
16718 (x_get_window_property, receive_incremental_selection)
16719 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
16720 (lisp_data_to_selection_data, clean_local_selection_data):
16721 Use ptrdiff_t, not int, to record length of selection.
16722 (x_reply_selection_request, x_get_window_property)
16723 (receive_incremental_selection, x_property_data_to_lisp):
16724 Redo calculations to avoid overflow.
16725 (x_reply_selection_request): When sending hint, ceiling it at

16728 (x_get_window_property, receive_incremental_selection)
16729 (lisp_data_to_selection_data, x_property_data_to_lisp):
16730 Check for size-calculation overflow.
16731 (x_get_window_property, receive_incremental_selection)
16732 (lisp_data_to_selection_data, Fx_register_dnd_atom):
16733 Don't store size until memory allocation succeeds.
16734 (x_get_window_property): Plug memory leak on memory exhaustion.
16735 Don't double-block input; malloc is safe here. Don't assume 2**34
16736 - 4 fits in unsigned long. Add an xassert to check
16737 XGetWindowProperty overflow. Be more careful about overflow
16738 calculations, and distinguish size from memory overflow better.
16739 (receive_incremental_selection): When tracing, don't assume
16740 unsigned int is less than INT_MAX.
16741 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16742 harmful) conversions of unsigned short to int.
16743 (lisp_data_to_selection_data): Don't assume that integers
16744 in the range -65535 through -1 fit in an X unsigned short.
16745 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16746 result parameters unless successful. Rely on cons_to_unsigned
16747 to report problems with elements; the old code wasn't right anyway.
16748 (x_check_property_data): Check for int overflow; we cannot use
16749 a wider type due to X limits.
16750 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
16752 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

16755 (x_term_init): Check for size calculation overflow.
16756 (x_color_cells): Don't store size until memory allocation succeeds.
16757 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
16758 Don't assume alloca size is less than MAX_ALLOCA.
16759 (x_term_init): Don't assume length fits in int (sprintf is limited
16762 Use ptrdiff_t for composition IDs.

16781 * image.c (xpm_get_color_table_h):
16782 * lisp.h (hash_lookup, hash_put):
16783 * minibuf.c (Ftest_completion):
16784 Use ptrdiff_t for hash table indexes, not int (which is too
16785 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16786 32-bit --with-wide-int hosts).
16788 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16789 Add a FIXME comment about memory leaks.
16790 (syms_of_charset): Don't assume xmalloc returns.
16792 Don't assume that stated character widths fit in int.

16794 * character.h (CHAR_WIDTH):
16795 * indent.c (MULTIBYTE_BYTES_WIDTH):
16796 Use sanitize_char_width to avoid undefined and/or bad behavior
16797 with outlandish widths.
16798 * character.h (sanitize_tab_width): Rename from sanitize_width,
16799 now that we have two such functions. All uses changed.
16800 (sanitize_char_width): New inline function.
16802 Don't assume that tab-width fits in int.
16803 * character.h (sanitize_width): New inline function.
16804 (SANE_TAB_WIDTH): New macro.
16805 (ASCII_CHAR_WIDTH): Use it.

16810 * fileio.c: Integer overflow issues with file modes.
16811 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
16813 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

16817 * xterm.c: Don't go over XClientMessageEvent limit.
16818 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16819 (x_send_scroll_bar_event): Likewise. Check that the size does not
16820 exceed limits imposed by XClientMessageEvent, as well as the usual
16821 ptrdiff_t and size_t limits.
16823 * keyboard.c: Overflow, signedness and related fixes.
16824 (make_lispy_movement): Use same integer type in forward decl
16825 that is used in the definition.
16826 (read_key_sequence, keyremap_step):
16827 Change bufsize argument back to int, undoing my 2011-03-30 change.
16828 We prefer signed types, and int is wide enough here.
16829 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16830 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16831 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16832 length, not size_t. Use ptrdiff_t for index, not int.
16833 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16834 possibility of integer overflow.
16836 Overflow, signedness and related fixes for images.
16838 * dispextern.h (struct it.stack[0].u.image.image_id)
16839 (struct_it.image_id, struct image.id, struct image_cache.size)
16840 (struct image_cache.used, struct image_cache.ref_count):

16846 * xdisp.c (calc_pixel_width_or_height):
16847 * xfns.c (image_cache_refcount):
16848 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
16849 on typical 64-bit hosts.

16857 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
16858 (lookup_image): Remove unnecessary tests.
16859 (xbm_image_p): Locals are now of int, not EMACS_INT,
16860 since parse_image_check makes sure they fit into int.
16861 (png_load, gif_load, svg_load_image):
16862 Prefer int to unsigned where either will do.
16863 (tiff_handler): New function, combining the cores of the
16864 old tiff_error_handler and tiff_warning_handler.
16865 This function is rewritten to use vsnprintf and thereby avoid
16866 stack buffer overflows. It uses only the features of vsnprintf
16867 that are common to both POSIX and native Microsoft.
16868 (tiff_error_handler, tiff_warning_handler): Use it.
16869 (tiff_load, gif_load, imagemagick_load_image):
16870 Don't assume :index value fits in 'int'.
16871 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16872 (imagemagick_load_image): Check that crop parameters fit into
16873 the integer types that MagickCropImage accepts. Don't assume
16874 Vimagemagick_render_type has a nonnegative value. Don't assume
16875 size_t fits in 'long'.
16876 (gs_load): Use printmax_t to print the widest integers possible.
16877 Check for integer overflow when computing image height and width.

16889 handle_single_display_spec, not just 1 or zero.
16890 (handle_single_display_spec): If the display spec is of the form
16891 `(space ...)', and specifies display in the text area, return 2
16893 (try_cursor_movement): Check for the need to scroll more
16894 accurately, and prefer exact match for point under bidi.
16895 Don't advance `row' beyond the last row of the window.
16897 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16898 into disp_prop; all users changed.

16913 buffers, return left-to-right.
16914 (set_cursor_from_row): Consider candidate row a win if its glyph
16915 represents a newline and point is on that newline. Fixes cursor
16916 positioning on the newline at EOL of R2L text within L2R
16917 paragraph, and vice versa.
16918 (try_cursor_movement): Check continued rows, in addition to
16919 continuation rows. Fixes unwarranted scroll when point enters a
16920 continued line of R2L text within an L2R paragraph, or vice versa.
16921 (cursor_row_p): Consider the case of point being equal to
16922 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

16948 * xdisp.c (redisplay_window): When computing centering_position,
16949 account for the height of the header line. (Bug#8874)
16951 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16952 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16953 candidate is selected by the mouse, and that candidate has a
16954 composed character under the mouse.
16956 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16957 coordinates reported by pos-visible-in-window-p for a composed
16958 character in column zero.

16967 consider it a hit if to_charpos is anywhere in the range of the
16968 composed buffer positions.
16970 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16972 * image.c (gif_load): Don't assume that each subimage has the same
16973 dimensions as the base image. Handle disposal method that is
16974 "undefined" by the gif spec (Bug#9335).

16984 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16985 from an Org mode buffer to a Speedbar frame.
16987 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16988 a composition, take its buffer position from IT->cmp_it.charpos.
16989 Fixes cursor positioning at the beginning of a line that begins
16990 with a composed character.
16992 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16994 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16995 character bidirectional type, use STRONG_L instead. Fixes crashes
16996 in a buffer produced by `describe-categories'.
16998 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16999 members before the level stack, so they would be saved and
17000 restored when copying iterator state. Fixes incorrect reordering
17001 around TABs covered by display properties.

17091 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17092 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit

17137 the iterator structure wrt the object coming from a display
17138 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17139 properties. (Bug#9284)

17342 * nsterm.m (ns_draw_text_decoration): New function for drawing
17343 underline, overline, and strike-through.
17344 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17345 ns_draw_text_decoration. Change treatment of cursor drawing to
17346 accommodate underlining, etc.
17348 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17350 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17353 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17355 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17356 Without this fix, if a signal arrives just after memory fills up,
17357 'malloc' might be invoked reentrantly.
17359 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17360 In other words, assume that every image size is allowed, on non-X
17361 hosts. This assumption is probably wrong, but it lets Emacs compile.
17363 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17365 * regex.c (re_iswctype): Convert return values to boolean.
17367 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17369 * xdisp.c (compute_display_string_pos): Don't use cached display
17370 string position if the buffer had its restriction changed.
17373 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17375 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17377 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17379 Integer signedness and overflow and related fixes. (Bug#9079)
17381 * bidi.c: Integer size and overflow fixes.
17382 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17383 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17384 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17385 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17386 (bidi_find_other_level_edge):
17387 Use ptrdiff_t instead of EMACS_INT where either will do.
17388 This works better on 32-bit hosts configured --with-wide-int.
17389 (bidi_cache_ensure_space): Check for size-calculation overflow.
17390 Use % rather than repeated addition, for better worst-case speed.
17391 Don't set bidi_cache_size until after xrealloc returns, because it
17393 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17394 (bidi_cache_ensure_space): Also check that the bidi cache size
17395 does not exceed that of the largest Lisp string or buffer. See Eli
17396 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17398 * alloc.c (__malloc_size_t): Remove.
17399 All uses replaced by size_t. See Andreas Schwab's note
17400 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17402 * image.c: Improve checking for integer overflow.
17403 (check_image_size): Assume that f is nonnull, since
17404 it is always nonnull in practice. This is one less thing to
17405 worry about when checking for integer overflow later.
17406 (x_check_image_size): New function, which checks for integer
17407 overflow issues inside X.
17408 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17409 This removes the need for a memory_full check.
17410 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17411 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17412 (xbm_read_bitmap_data): Change locals back to 'int', since
17413 their values must fit in 'int'.
17414 (xpm_load_image, png_load, tiff_load):
17415 Invoke x_create_x_image_and_pixmap earlier,
17416 to avoid much needless work if the image is too large.
17417 (tiff_load): Treat overly large images as if
17418 x_create_x_image_and_pixmap failed, not as malloc failures.
17419 (gs_load): Use x_check_image_size.
17421 * gtkutil.c: Omit integer casts.
17422 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17423 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17425 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17427 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17428 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17429 would wrongly return t on a 64-bit host.
17431 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17432 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17433 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17434 and therefore cause GCC to emit a bogus diagnostic in some cases.
17436 * image.c: Integer signedness and overflow and related fixes.
17437 This is not an exhaustive set of fixes, but it's time to
17438 record what I've got.
17439 (lookup_pixel_color, check_image_size): Remove redundant decls.
17440 (check_image_size): Don't assume that arbitrary EMACS_INT values
17441 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17442 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17443 (tiff_load, imagemagick_load_image):
17444 Check for overflow in size calculations.
17445 (x_create_x_image_and_pixmap): Remove unnecessary test for
17446 xmalloc returning NULL; that can't happen.
17447 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17448 (xpm_color_bucket): Use better integer hashing function.
17449 (xpm_cache_color): Don't possibly over-allocate memory.
17450 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17451 (gif_memory_source):
17452 Use ptrdiff_t, not int or size_t, to record sizes.
17453 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17454 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17455 either works, as we prefer signed integers.
17456 (tiff_read_from_memory, tiff_write_from_memory):
17457 Return tsize_t, not size_t, since that's what the TIFF API wants.
17458 (tiff_read_from_memory): Don't fail simply because the read would
17459 go past EOF; instead, return a short read.
17460 (tiff_load): Omit no-longer-needed casts.
17461 (Fimagemagick_types): Don't assume size fits into 'int'.
17463 Improve hashing quality when configured --with-wide-int.
17464 * fns.c (hash_string): New function, taken from sxhash_string.
17465 Do not discard information about ASCII character case; this
17466 discarding is no longer needed.
17467 (sxhash-string): Use it. Change sig to match it. Caller changed.
17468 * lisp.h: Declare it.
17469 * lread.c (hash_string): Remove, since we now use fns.c's version.
17470 The fns.c version returns a wider integer if --with-wide-int is
17471 specified, so this should help the quality of the hashing a bit.
17473 * emacs.c: Integer overflow minor fix.
17474 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17475 Define only if GNU_LINUX.
17476 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17478 * dispnew.c: Integer signedness and overflow fixes.
17479 Remove unnecessary forward decls, that were a maintenance hassle.
17480 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17482 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17483 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17484 (prepare_desired_row, line_draw_cost):
17485 Use int, not unsigned, where either works.
17486 (save_current_matrix, restore_current_matrix):
17487 Use ptrdiff_t, not size_t, where either works.
17488 (init_display): Check for overflow more accurately, and without
17489 relying on undefined behavior.
17491 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17492 Remove, replacing with the new symbols in lisp.h. All uses changed.
17493 * fileio.c (make_temp_name):
17494 * filelock.c (lock_file_1, lock_file):
17495 * xdisp.c (message_dolog):
17496 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17497 Use pMd etc. instead.
17498 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17499 replacing the pWIDE etc. symbols removed from editfns.c.
17501 * keyboard.h (num_input_events): Now uintmax_t.
17502 This is (very slightly) less likely to mess up due to wraparound.
17505 * buffer.c: Integer signedness fixes.
17506 (alloc_buffer_text, enlarge_buffer_text):
17507 Use ptrdiff_t rather than size_t when either will do, as we prefer
17510 * alloc.c: Integer signedness and overflow fixes.
17511 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17512 (__malloc_size_t): Default to size_t, not to int.
17513 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17514 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17515 Prefer ptrdiff_t to size_t when either would do, as we prefer
17517 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17518 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17519 Now const. Initialize with values that are in range even if char
17521 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17522 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17523 These functions do the right thing with sizes > 2**32.
17524 (check_depth): Now ptrdiff_t, not int.
17525 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17526 Adjust to new way of storing sizes. Check for size overflow bugs
17528 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17529 slightly wrong anyway, as it missed one instance of
17530 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17531 (refill_memory_reserve): Omit needless cast to size_t.
17532 (mark_object_loop_halt): Mark as externally visible.
17534 * xselect.c: Integer signedness and overflow fixes.
17535 (Fx_register_dnd_atom, x_handle_dnd_message):
17536 Use ptrdiff_t, not size_t, since we prefer signed.
17537 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17538 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17539 x_dnd_atoms_size and x_dnd_atoms_length.
17541 * doprnt.c: Prefer signed to unsigned when either works.
17543 * doprnt.c (doprnt):
17545 * xdisp.c (vmessage):
17546 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17547 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17548 prefer signed arithmetic to avoid comparison confusion.
17549 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17550 but is a bit tricky.
17552 Assume freestanding C89 headers, string.h, stdlib.h.
17553 * data.c, doprnt.c, floatfns.c, print.c:
17554 Include float.h unconditionally.
17555 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17556 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17557 * regex.c: Likewise for stddef.h, string.h.
17558 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17559 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17560 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17561 (STDC_HEADERS): Remove obsolete defines.
17562 * sysdep.c: Include limits.h unconditionally.
17564 Assume support for memcmp, memcpy, memmove, memset.
17565 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17566 * regex.c (memcmp, memcpy):
17567 Remove; we assume C89 now.
17569 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17570 (__malloc_safe_bcopy): Remove; no longer needed.
17572 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17573 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17574 well either way, and we prefer signed to unsigned.
17576 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17578 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17579 closes the connection while we're reading (bug#9182).
17581 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17583 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17584 are specified (Bug#9168).
17586 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17588 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17589 Found by GCC static checking and --with-wide-int on a 32-bit host.
17591 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17593 * xdisp.c (compute_display_string_pos): Fix logic of caching
17594 previous display string position. Initialize cached_prev_pos to
17595 -1. Fixes slow-down at the beginning of a buffer.
17597 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17599 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17600 for attrs[LFACE_FONTSET_INDEX].
17602 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17604 * xml.c (parse_region): Remove unused local
17605 that was recently introduced.
17607 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17609 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17610 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17612 * xdisp.c (move_it_in_display_line_to): Record the best matching
17613 position for TO_CHARPOS while scanning the line, and restore it on
17614 exit if none of the characters scanned was an exact match.
17615 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17616 when exact match is impossible due to invisible text, and the
17617 lines are truncated.
17619 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17621 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17624 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17626 Fix a significant slow-down of cursor motion with C-n, C-p,
17627 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17628 auto-repeat under bidi redisplay in fontified buffers.
17629 * xdisp.c (compute_stop_pos_backwards): New function.
17630 (next_element_from_buffer): Call compute_stop_pos_backwards to
17631 find a suitable prev_stop when we find ourselves before
17633 (reseat): Don't look for prev_stop, as that could mean a very long
17635 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17636 <cached_disp_overlay_modiff>: Cache for last found display string
17638 (compute_display_string_pos): Return the cached position if asked
17639 about the same buffer in the same area of character positions, and
17640 the buffer wasn't changed since the time the display string
17641 position was cached.
17643 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17645 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17646 is an integer, which is important for empty lines. (Bug#9149)
17648 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17650 * frame.c (Fmodify_frame_parameters): In tty case, update the
17651 default face if necessary (Bug#4238).
17653 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17655 * editfns.c (Fstring_to_char): No need to explain what a character
17656 is in the docstring (Bug#6576).
17658 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17660 * xml.c (parse_region): Make sure we always return a tree.
17662 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17664 * xml.c (parse_region): If a document contains only comments,
17667 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17669 * xml.c (make_dom): Return comments, too.
17671 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17674 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17675 and the surrounding thread.
17676 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17677 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17678 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17680 * s/openbsd.h (BROKEN_SIGIO): Define.
17681 * unexelf.c (unexec) [__OpenBSD__]:
17682 Don't update the .mdebug section of the Alpha COFF symbol table.
17684 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17686 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17689 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17691 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17692 This fixes some race conditions on the permissions of any newly
17695 * alloc.c (valid_pointer_p): Use pipe, not open.
17696 This fixes some permissions issues when debugging.
17698 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17699 If fchown fails to set both uid and gid, try to set just gid,
17700 as that is sometimes allowed. Adjust the file's mode to eliminate
17701 setuid or setgid bits that are inappropriate if fchown fails.
17703 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17705 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17706 to compare Lisp_Objects.
17707 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17708 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17709 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17711 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17713 * lread.c (read_integer): Unread even EOF character.
17714 (read1): Likewise. Properly record start position of symbol.
17716 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17717 symbol character follows.
17719 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17721 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17722 This works around a problem with the previous change to Fcopy_file.
17723 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17724 and without this change, GCC might complain about discarding
17725 fchown's return value.
17727 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17729 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17731 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17733 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17735 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17737 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17738 it's used from the C level.
17740 * process.c: Use the same condition for POLL_FOR_INPUT in both
17741 keyboard.c and process.c (bug#1858).
17743 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17745 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17746 (Fgnutls_boot): Use it.
17748 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17750 * doc.c (Fsubstitute_command_keys): Revert last change.
17752 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17754 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17755 quotes the next character, and doesn't affect other longer
17756 sequences (bug#8935).
17758 * lread.c (syms_of_lread): Clarify that is isn't only
17759 `eval-buffer' and `eval-defun' that's affected by
17760 `lexical-binding' (bug#8460).
17762 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17764 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17765 bidi redisplay when a line includes both an image and is truncated.
17767 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17769 Fix minor problems found by static checking.
17770 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17771 (elsz): Now a signed constant, not a size_t var. We prefer signed
17772 types to unsigned, to avoid integer comparison confusion. Without
17773 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17774 "cannot optimize loop, the loop counter may overflow", a symptom
17776 * indent.c (Fvertical_motion): Mark locals as initialized.
17777 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17779 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

18301 (clone_per_buffer_values): Don't assume that

18303 This isn't true in general, and it's particularly not true
18304 if Emacs is configured with --with-wide-int.
18305 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
18306 New macros, used in the buffer.c change.

18342 Random fixes. E.g., (random) never returned negative values.
18343 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18344 subseconds part to the entropy, as that's a bit more random.
18345 Prefer signed to unsigned, since the signedness doesn't matter and
18346 in general we prefer signed. When given a limit, use a
18347 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18348 latter isn't right if USE_2_TAGS_FOR_INTS.
18349 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18350 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18362 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18363 This is more efficient than Ffile_directory_p and avoids a minor race.

18367 * buffer.c (Foverlay_put): Say what the return value is
18370 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18371 is a directory before asking whether to use the file name

18374 error be more correct.
18376 * fns.c (Frequire): Remove the mention of the .gz files, since
18377 that's installation-specific, but keep the mention of

18390 Qgnutls_bootprop_verify_error (which is no longer used).
18392 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18393 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18394 Also (re)move comments that are misplaced or no longer relevant.
18396 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
18398 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

18423 * lread.c (syms_of_lread): Mention single symbols defined by

18495 * eval.c (struct backtrace): Simplify and port the data structure.
18496 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18497 signed bit field, as this assumption is not portable and it makes
18498 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18499 "char debug_on_exit : 1" as this is not portable either; instead,
18500 use the portable "unsigned int debug_on_exit : 1". Remove unused
18501 member evalargs. Remove obsolete comments about cc bombing out.
18503 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18657 * xmenu.c (syms_of_xmenu):
18658 * xsettings.c (syms_of_xsettings):
18659 * xterm.c (syms_of_xterm): Use DEFSYM.
18661 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
18663 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
18665 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
18667 Integer and buffer overflow fixes (Bug#8873).
18669 * print.c (printchar, strout): Check for string overflow.
18670 (PRINTPREPARE, printchar, strout):
18671 Don't set size unless allocation succeeds.
18673 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18674 for sizes. Check for string overflow more accurately.
18675 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
18677 * macros.c: Integer and buffer overflow fixes.
18678 * keyboard.h (struct keyboard.kbd_macro_bufsize):
18679 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
18680 Use ptrdiff_t, not int, for sizes.
18681 Don't increment bufsize until after realloc succeeds.
18682 Check for size-calculation overflow.
18683 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
18685 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
18687 * lread.c: Integer overflow fixes.
18688 (read_integer): Radix is now EMACS_INT, not int,
18689 to improve quality of diagnostics for out-of-range radices.
18690 Calculate buffer size correctly for out-of-range radices.
18691 (read1): Check for integer overflow in radices, and in
18692 read-circle numbers.
18693 (read_escape): Avoid int overflow.
18694 (Fload, openp, read_buffer_size, read1)
18695 (substitute_object_recurse, read_vector, read_list, map_obarray):
18696 Use ptrdiff_t, not int, for sizes.
18697 (read1): Use EMACS_INT, not int, for sizes.
18698 Check for size overflow.
18700 * image.c (cache_image): Check for size arithmetic overflow.
18702 * lread.c: Integer overflow issues.
18703 (saved_doc_string_size, saved_doc_string_length)
18704 (prev_saved_doc_string_size, prev_saved_doc_string_length):
18705 Now ptrdiff_t, not int.
18706 (read1): Don't assume doc string length fits in int. Check for
18707 out-of-range doc string lengths.

18709 (read_escape): Check for hex character overflow.
18711 2011-06-22 Leo Liu <sdl.web@gmail.com>
18713 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
18714 Move to minibuffer.el.
18716 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18718 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18719 The following patches are for when GLYPH_DEBUG && !XASSERT.
18720 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18721 * dispnew.c (flush_stdout):
18722 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18723 Mark as externally visible.
18724 * dispnew.c (check_window_matrix_pointers): Now static.
18725 * dispnew.c (window_to_frame_vpos):
18726 * xfns.c (unwind_create_frame):
18727 * xterm.c (x_check_font): Remove unused local.
18728 * scroll.c (CHECK_BOUNDS):
18729 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18730 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18731 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18732 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18733 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18735 (debug_method_add): Use va_list and vsprintf rather than relying
18736 on undefined behavior with wrong number of arguments.
18737 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18738 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18739 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18740 since we're not interested in debugging glyphs with old libraries.
18741 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18742 GCC 4.6.0's static checking.
18744 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18746 Integer overflow and signedness fixes (Bug#8873).

18754 (x_create_bitmap_from_data, x_create_bitmap_from_file)
18755 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
18756 (x_create_bitmap_from_xpm_data):
18757 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
18758 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
18760 * xfaces.c (load_pixmap):
18761 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
18762 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18763 (.bitmaps_last, struct x_output.icon_bitmap):
18764 Use ptrdiff_t, not int, for bitmap indexes.
18765 (x_allocate_bitmap_record): Check for size overflow.
18766 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18768 Use ptrdiff_t, not int, for overlay counts.
18769 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18770 * editfns.c (overlays_around, get_pos_property):
18771 * textprop.c (get_char_property_and_overlay):
18772 * xdisp.c (next_overlay_change, note_mouse_highlight):
18773 * xfaces.c (face_at_buffer_position):
18774 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18775 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18776 (Fnext_overlay_change, Fprevious_overlay_change)
18777 (mouse_face_overlay_overlaps, Foverlays_in):
18778 Use ptrdiff_t, not int, for sizes.
18779 (overlays_at, overlays_in): Check for size-calculation overflow.
18781 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18783 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18784 (x_session_initialize): Do not assume string length fits in int.
18786 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18787 This is unlikely, but can occur if DPI is outlandish.
18789 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18790 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18792 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18793 * xrdb.c (magic_file_p, search_magic_path):
18794 Omit last arg SUFFIX; it was always 0. All callers changed.
18795 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18797 * xfont.c (xfont_match): Avoid need for strlen.
18799 * xfns.c: Don't assume strlen fits in int.
18800 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18802 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18803 not unsigned long, as we prefer signed integers. All callers changed.
18804 Detect integer overflow in repeat count.
18805 (message_dolog): Don't assume print length fits in 39 bytes.
18806 (display_mode_element): Don't assume strlen fits in int.
18808 * termcap.c: Don't assume sizes fit in int and never overflow.
18809 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18810 (gobble_line): Check for size-calculation overflow.
18812 * minibuf.c (Fread_buffer):
18813 * lread.c (intern, intern_c_string):
18814 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
18815 Don't assume string length fits in int.
18817 * keyboard.c (parse_tool_bar_item):
18818 * gtkutil.c (style_changed_cb): Avoid need for strlen.
18820 * font.c: Don't assume string length fits in int.
18821 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18822 Use ptrdiff_t, not int.
18823 (font_intern_prop): Don't assume string length fits in int.
18824 Don't assume integer property fits in fixnum.
18825 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18827 * filelock.c: Fix some buffer overrun and integer overflow issues.
18828 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18829 Reformulate so as not to need the command string.
18830 Invoke gzip -cd rather than gunzip, as it's more portable.
18831 (lock_info_type, lock_file_1, lock_file):
18832 Don't assume pid_t and time_t fit in unsigned long.
18833 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18834 (current_lock_owner): Prefer signed type for sizes.
18835 Use memcpy, not strncpy, where memcpy is what is really wanted.
18836 Don't assume (via atoi) that time_t and pid_t fit in int.
18837 Check for time_t and/or pid_t out of range, e.g., via a network share.
18838 Don't alloca where an auto var works fine.
18840 * fileio.c: Fix some integer overflow issues.
18841 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18842 Don't assume string length fits in int.
18843 (directory_file_name): Don't assume string length fits in long.
18844 (make_temp_name): Don't assume pid fits in int, or that its print
18845 length is less than 20.
18847 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18849 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18851 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18853 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18854 We prefer signed integers, even for size calculations.
18856 * emacs.c: Don't assume string length fits in 'int'.
18857 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18858 (main): Don't invoke strlen when not needed.
18860 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18861 (XD_DEBUG_MESSAGE): Don't waste a byte.
18863 * callproc.c (getenv_internal_1, getenv_internal)
18864 (Fgetenv_internal):
18865 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18867 * lread.c (invalid_syntax): Omit length argument.
18868 All uses changed. This doesn't fix a bug, but it simplifies the
18869 code away from its former Hollerith-constant appearance, and it's
18870 one less 'int' to worry about when looking at integer-overflow issues.
18871 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18873 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18874 This didn't break anything, but it didn't help either.
18875 It's confusing to put a bogus integer in a place where the actual
18876 value does not matter.
18877 (LIST_END_P): Remove unused macro and its bogus comment.
18878 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18880 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18881 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18883 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18884 We prefer signed types, and the value cannot exceed the EMACS_INT
18885 range anyway (because otherwise the length would not be representable).
18886 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18887 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18888 This avoids a GCC warning when WIDE_EMACS_INT.
18890 * indent.c (sane_tab_width): New function.
18891 (current_column, scan_for_column, Findent_to, position_indentation)
18892 (compute_motion): Use it. This is just for clarity.
18893 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18895 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18897 * lisp.h (lint_assume): New macro.
18898 * composite.c (composition_gstring_put_cache):
18899 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18901 * editfns.c, insdel.c:
18902 Omit unnecessary forward decls, to simplify future changes.
18904 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18906 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18908 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18909 Use much-faster test for byte-length change.
18910 Don't assume string byte-length fits in 'int'.
18911 Check that character arg fits in 'int'.
18912 (mapcar1): Declare byte as byte, for clarity.
18914 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18916 * fns.c (concat): Catch string overflow earlier.
18917 Do not rely on integer wraparound.
18919 * dispextern.h (struct it.overlay_strings_charpos)
18920 (struct it.selective): Now EMACS_INT, not int.
18921 * xdisp.c (forward_to_next_line_start)
18922 (back_to_previous_visible_line_start)
18923 (reseat_at_next_visible_line_start, next_element_from_buffer):
18924 Don't arbitrarily truncate the value of 'selective' to int.
18926 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18928 * composite.c: Don't truncate sizes to 'int'.
18929 (composition_gstring_p, composition_reseat_it)
18930 (composition_adjust_point): Use EMACS_INT, not int.
18931 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18932 not EMACS_UINT, for indexes.
18934 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18936 * buffer.c: Include <verify.h>.
18937 (struct sortvec.priority, struct sortstr.priority):
18938 Now EMACS_INT, not int.
18939 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18940 (struct sortstr.size, record_overlay_string)
18941 (struct sortstrlist.size, struct sortlist.used):
18942 Don't truncate size to int.
18943 (record_overlay_string): Check for size-calculation overflow.
18944 (init_buffer_once): Check at compile-time, not run-time.
18946 2011-06-22 Jim Meyering <meyering@redhat.com>
18948 Don't leak an XBM-image-sized buffer
18949 * image.c (xbm_load): Free the image buffer after using it.
18951 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18954 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18955 that Sun C diagnosed.
18956 * fns.c (secure_hash): Fix pointer signedness issue.
18957 * intervals.c (static_offset_intervals): New function.
18958 (offset_intervals): Use it.
18960 2011-06-21 Leo Liu <sdl.web@gmail.com>
18963 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18966 * fns.c (secure_hash): Rename from crypto_hash_function and change
18967 the first arg to accept symbols.
18968 (Fsecure_hash): New primitive.
18969 (syms_of_fns): New symbols.
18971 2011-06-20 Deniz Dogan <deniz@dogan.se>
18973 * process.c (Fset_process_buffer): Clarify return value in
18976 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18978 * dispnew.c (add_window_display_history): Use BVAR.
18980 * xdisp.c (debug_method_add): Use BVAR.
18981 (check_window_end, dump_glyph_matrix, dump_glyph)
18982 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18984 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18987 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18988 check till after the cache is created in init_frame_faces.
18990 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18992 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18994 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18996 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18997 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18998 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19000 Improve buffer-overflow checking (Bug#8873).
19001 * fileio.c (Finsert_file_contents):
19002 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19003 Remove the old (too-loose) buffer overflow checks.
19004 They weren't needed, since make_gap checks for buffer overflow.
19005 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19006 The old code merely checked for Emacs fixnum overflow, and relied
19007 on undefined (wraparound) behavior. The new code avoids undefined
19008 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19010 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19011 Tune. Don't use wider integers than needed. Don't use alloca.
19012 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19014 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19016 * insdel.c, lisp.h (buffer_overflow): New function.
19017 (insert_from_buffer_1, replace_range, replace_range_2):
19018 * insdel.c (make_gap_larger):
19019 * editfns.c (Finsert_char):
19020 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19022 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19024 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19026 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19028 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19029 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19031 * fileio.c: Don't assume EMACS_INT fits in off_t.
19032 (emacs_lseek): New static function.
19033 (Finsert_file_contents, Fwrite_region): Use it.
19034 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19036 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19038 * fns.c: Don't overflow int when computing a list length.
19039 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19040 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19041 truncation on 64-bit hosts. Check for QUIT every
19042 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19043 faster and is responsive enough.
19044 (Flength): Report an error instead of overflowing an integer.
19045 (Fsafe_length): Return a float if the value is not representable
19046 as a fixnum. This shouldn't happen except in contrived situations.
19047 (Fnthcdr, Fsort): Don't assume list length fits in int.
19048 (Fcopy_sequence): Don't assume vector length fits in int.
19050 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19051 (header_size, word_size): New constants.
19052 (allocate_vectorlike): Don't check size overflow here.
19053 (allocate_vector): Check it here instead, since this is the only
19054 caller of allocate_vectorlike that could cause overflow.
19055 Check that the new vector's length is representable as a fixnum.
19057 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19058 The previous code was bogus. For example, next_almost_prime (32)
19059 returned 39, which is undesirable as it is a multiple of 3; and
19060 next_almost_prime (24) returned 25, which is a multiple of 5 so
19061 why was the code bothering to check for multiples of 7?
19063 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19065 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19067 Variadic C functions now count arguments with ptrdiff_t.
19068 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19069 Back then I didn't know that the Emacs coding style prefers signed int.
19070 Also, in the meantime I found a few more instances where arguments
19071 were being counted with int, which may truncate counts on 64-bit
19072 machines, or EMACS_INT, which may be unnecessarily wide.
19073 * lisp.h (struct Lisp_Subr.function.aMANY)
19074 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19075 Arg counts are now ptrdiff_t, not size_t.
19076 All variadic functions and their callers changed accordingly.
19077 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19078 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19079 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19080 * callint.c (Fcall_interactively): Check arg count for overflow,
19081 to avoid potential buffer overrun. Use signed char, not 'int',
19082 for 'varies' array, so that we needn't bother to check its size
19083 calculation for overflow.
19084 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19085 * eval.c (apply_lambda):
19086 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19087 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19088 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19090 * callint.c (Fcall_interactively): Don't use index var as event count.
19092 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19093 * mem-limits.h (SIZE): Remove; no longer used.
19095 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19097 Remove unnecessary casts.
19098 * xterm.c (x_term_init):
19099 * xfns.c (x_set_border_pixel):
19100 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19101 These aren't needed now that we assume ANSI C.
19103 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19104 It's more likely to cause problems (due to unsigned overflow)
19107 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19109 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19111 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19113 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19115 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19117 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19119 GLYPH_CODE_FACE returns EMACS_INT, not int.
19120 * dispextern.h (merge_faces):
19121 * xfaces.c (merge_faces):
19122 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19123 Don't assume EMACS_INT fits in int.
19125 * character.h (CHAR_VALID_P): Remove unused parameter.
19126 * fontset.c, lisp.h, xdisp.c: All uses changed.
19128 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19130 * fns.c (concat): Minor tuning based on overflow analysis.
19131 This doesn't fix any bugs. Use int to hold character, instead
19132 of constantly refetching from Emacs object. Use XFASTINT, not
19133 XINT, for value known to be a character. Don't bother comparing
19134 a single byte to 0400, as it's always less.
19136 * floatfns.c (Fexpt):
19137 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19139 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19142 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19144 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19145 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19146 incorrectly succeed when S was a string, because 4294967386 was
19147 truncated before it was used.
19149 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19150 Otherwise, an out-of-range integer could cause undefined behavior
19153 * composite.c: Use int, not EMACS_INT, for characters.
19154 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19155 EMACS_INT, for values that are known to be in character range.
19156 This doesn't fix any bugs but is the usual style inside Emacs and
19157 may generate better code on 32-bit machines.
19159 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19160 This is for reasons similar to the recent CHAR_STRING fix.
19161 * charset.c (Fencode_char): Check that character arg is actually
19162 a character. Pass an int to ENCODE_CHAR.
19163 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19164 wider than 'int', as a compile-time check to prevent future regressions
19167 * character.c (char_string): Remove unnecessary casts.
19169 Make sure a 64-bit char is never passed to CHAR_STRING.
19170 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19171 by silently ignoring the top 32 bits, allowing some values
19172 that were far too large to be valid characters.
19173 * character.h: Include <verify.h>.
19174 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19175 arguments are no wider than unsigned, as a compile-time check
19176 to prevent future regressions in this area.
19178 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19179 (Fsubst_char_in_region):
19181 * xdisp.c (decode_mode_spec_coding):
19182 Adjust to CHAR_STRING's new requirement.
19183 * editfns.c (Finsert_char, Fsubst_char_in_region):
19184 * fns.c (concat): Check that character args are actually
19185 characters. Without this test, these functions did the wrong
19186 thing with wildly out-of-range values on 64-bit hosts.
19188 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19189 These casts should not be needed on 32-bit hosts, either.
19190 * keyboard.c (read_char):
19191 * lread.c (Fload): Remove casts to unsigned.
19193 * lisp.h (UNSIGNED_CMP): New macro.
19194 This fixes comparison bugs on 64-bit hosts.
19195 (ASCII_CHAR_P): Use it.
19196 * casefiddle.c (casify_object):
19197 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19198 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19199 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19200 * dispextern.h (FACE_FROM_ID):
19201 * keyboard.c (read_char): Use UNSIGNED_CMP.
19203 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19204 not to EMACS_INT, to avoid GCC warning.
19206 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19208 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19209 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19210 isn't needed on 32-bit machines.
19212 * buffer.c (Fgenerate_new_buffer_name):
19213 Use EMACS_INT for count, not int.
19214 (advance_to_char_boundary): Return EMACS_INT, not int.
19216 * data.c (Qcompiled_function): Now static.
19218 * window.c (window_body_lines): Now static.
19220 * image.c (gif_load): Rename local to avoid shadowing.
19222 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19223 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19224 * alloc.c (make_save_value): Integer argument is now of type
19225 ptrdiff_t, not int.
19226 (mark_object): Use ptrdiff_t, not int.
19227 * lisp.h (pD): New macro.
19228 * print.c (print_object): Use it.
19230 * alloc.c: Use EMACS_INT, not int, to count objects.
19231 (total_conses, total_markers, total_symbols, total_vector_size)
19232 (total_free_conses, total_free_markers, total_free_symbols)
19233 (total_free_floats, total_floats, total_free_intervals)
19234 (total_intervals, total_strings, total_free_strings):
19235 Now EMACS_INT, not int. All uses changed.
19236 (Fgarbage_collect): Compute overall total using a double, so that
19237 integer overflow is less likely to be a problem. Check for overflow
19238 when converting back to an integer.
19239 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19240 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19241 These were 'int' variables that could overflow on 64-bit hosts;
19242 they were never used, so remove them instead of repairing them.
19243 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19244 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19245 Previously, this ceilinged at INT_MAX, but that doesn't work on
19247 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19249 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19250 (allocate_vectorlike): Check for ptrdiff_t overflow.
19251 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19252 when a (possibly-narrower) signed value would do just as well.
19253 We prefer using signed arithmetic, to avoid comparison confusion.
19255 * alloc.c: Catch some string size overflows that we were missing.
19256 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19257 for convenience in STRING_BYTES_MAX.
19258 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19259 The definition here is exact; the one in lisp.h was approximate.
19260 (allocate_string_data): Check for string overflow. This catches
19261 some instances we weren't catching before. Also, it catches
19262 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19263 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19264 and ptrdiff_t and EMACS_INT are both 64 bits.
19266 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19267 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19268 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19270 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19272 * alloc.c (Fmake_string): Check for out-of-range init.
19274 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19276 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
19278 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
19280 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

19283 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
19284 (int_gtk_range_get_value): Move to the scroll bar part of the file.
19285 (style_changed_cb): Call update_theme_scrollbar_width and call
19286 x_set_scroll_bar_default_width and xg_frame_set_char_size for
19287 all frames (Bug#8505).
19288 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
19289 Call gtk_window_set_resizable if HAVE_GTK3.

19291 and height if HAVE_GTK3 (Bug#8505).
19292 (scroll_bar_width_for_theme): New variable.
19293 (update_theme_scrollbar_width): New function.
19294 (xg_get_default_scrollbar_width): Move code to
19295 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
19296 (xg_initialize): Call update_theme_scrollbar_width.
19298 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
19300 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
19302 2011-06-12 Martin Rudalics <rudalics@gmx.at>
19304 * frame.c (make_frame): Call other_buffer_safely instead of
19307 * window.c (temp_output_buffer_show): Call display_buffer with
19308 second argument Vtemp_buffer_show_specifiers and reset latter
19309 immediately after the call.
19310 (Vtemp_buffer_show_specifiers): New variable.
19311 (auto_window_vscroll_p, next_screen_context_lines)
19312 (Vscroll_preserve_screen_position): Remove leading asterisks from

19358 (Fset_window_configuration): Rewrite to handle dead buffers and
19359 consequently deletable windows.
19360 (window_tree, Fwindow_tree): Remove. Supply functionality in

19495 Remove static from declaration of Qdelete_window, it's
19496 temporarily needed by Fbury_buffer.
19497 (replace_window): Don't assign orig_top_line and
19499 (Fdelete_window, delete_window): Remove. Window deletion is

19501 (window_loop): Remove DELETE_OTHER_WINDOWS case.
19502 Replace Fdelete_window calls with calls to Qdelete_window.
19503 (Fdelete_other_windows): Remove. Deleting other windows is

19909 Without this change, the gnutls library would invoke malloc etc.
19910 directly, which causes problems on non-SYNC_INPUT hosts, and which
19911 runs afoul of improving memory_full behavior. (Bug#8761)
19912 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19913 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19914 xfree instead of the default malloc, realloc, free.
19915 (Fgnutls_boot): No need to check for memory allocation failure,
19916 since xmalloc does that for us.

19945 need to be updated by these changes.
19946 * fns.c (make_hash_table, maybe_resize_hash_table):
19947 Check for integer overflow with large hash tables.
19948 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19949 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19950 (SXHASH_REDUCE): New macro.
19951 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19952 Use it instead of discarding useful hash info with large hash values.

19954 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19955 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19956 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19957 Rewrite to use FIXNUM_BITS, as this simplifies things.
19958 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19959 Adjust signatures to match updated version of code.
19960 (consing_since_gc): Now EMACS_INT, since a single hash table can
19961 use more than INT_MAX bytes.
19963 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19965 Make it possible to build with GCC-4.6+ -O2 -flto.
19967 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19969 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19971 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19972 Call minibuffer-inactive-mode.
19974 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19976 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19977 Update dependencies.
19979 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19981 * data.c (init_data): Remove code for UTS, this system is not
19984 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19986 Don't force ./temacs to start in terminal mode.
19988 * frame.c (make_initial_frame): Initialize faces in all cases, not
19989 only when CANNOT_DUMP is defined.
19990 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19992 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19994 * dispnew.c (add_window_display_history): Use const for the string
19995 pointer. Remove declaration, not needed.
19997 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19999 Use 'inline', not 'INLINE'.
20000 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20001 * alloc.c, fontset.c (INLINE): Remove.
20002 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20003 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20004 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20005 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20006 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20008 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20010 Make it possible to run ./temacs.
20012 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20013 syms_of_callproc does the same thing. Remove test for
20014 "initialized", do it in the caller.
20015 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20017 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20019 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20020 (read_minibuf): Use get_minibuffer.
20021 (syms_of_minibuf): Use DEFSYM.
20022 (Qmetadata): New var.
20023 * data.c (Qbuffer): Don't make it static.
20024 (syms_of_data): Use DEFSYM.
20026 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20028 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20029 (CCL_CODE_MIN): New macro.
20031 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20033 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20035 * eval.c (Qdebug): Now static.
20036 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20037 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20038 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20040 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20042 * image.c: Various fixes to ImageMagick code comments.
20043 (Fimagemagick_types): Doc fix.
20045 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20047 Minor fixes prompted by GCC 4.6.0 warnings.
20049 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20051 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20052 (x_clipboard_manager_save_all): Move extern decl to ...
20053 * xterm.h: ... here, so that it can be checked for consistency.
20055 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20057 * xselect.c (x_clipboard_manager_save_frame)
20058 (x_clipboard_manager_save_all): New functions.
20059 (Fx_clipboard_manager_save): Lisp function deleted.
20061 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20062 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20064 * xterm.h: Update prototype.
20066 2011-05-28 William Xu <william.xwl@gmail.com>
20068 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20069 exiting (Bug#8239).
20071 2011-05-28 Jim Meyering <meyering@redhat.com>
20073 Avoid a sign-extension bug in crypto_hash_function.
20074 * fns.c (to_uchar): Define.
20075 (crypto_hash_function): Use it to convert some newly-signed
20076 variables to unsigned, to avoid sign-extension bugs. For example,
20077 without this change, (md5 "truc") would evaluate to
20078 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20079 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20080 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20082 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20084 Integer overflow fixes.
20086 * dbusbind.c: Serial number integer overflow fixes.
20087 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20088 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20089 to hold a serial number that is too large for a fixnum.
20090 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20091 Check for serial numbers out of range. Decode any serial number
20092 that was so large that it became a float. (Bug#8722)
20094 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20095 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20096 Use XFASTINT rather than XUINT when numbers are nonnegative.
20097 (xd_append_arg, Fdbus_method_return_internal):
20098 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20099 arguments, check that Lisp number is nonnegative, rather than
20100 silently wrapping negative numbers around. (Bug#8722)
20101 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20104 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20106 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20108 ccl: Add integer overflow checks.
20109 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20110 (IN_INT_RANGE): New macros.
20111 (ccl_driver): Use them to check for integer overflow when
20112 decoding a CCL program. Many of the new checks are whether XINT (x)
20113 fits in int; it doesn't always, on 64-bit hosts. The new version
20114 doesn't catch all possible integer overflows, but it's an
20115 improvement. (Bug#8719)
20117 * alloc.c (make_event_array): Use XINT, not XUINT.
20118 There's no need for unsigned here.
20120 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20121 This follows up to the 2011-05-06 change that substituted uintptr_t
20122 for EMACS_INT. This case wasn't caught back then.
20124 Rework Fformat to avoid integer overflow issues.
20125 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20126 now (part of C89). Include <verify.h>.
20127 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20128 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20129 (Fformat): Avoid the prepass trying to compute sizes; it was only
20130 approximate and thus did not catch overflow reliably. Instead, walk
20131 through the format just once, formatting and computing sizes as we go,
20132 checking for integer overflow at every step, and allocating a larger
20133 buffer as needed. Keep track separately whether the format is
20134 multibyte. Keep only the most-recently calculated precision, rather
20135 than them all. Record whether each argument has been converted to
20136 string. Use EMACS_INT, not int, for byte and char and arg counts.
20137 Support field widths and precisions larger than INT_MAX. Avoid
20138 sprintf's undefined behavior with conversion specifications such as %#d
20139 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20140 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20141 formatting out-of-range floating point numbers with int
20142 formats. (Bug#8668)
20144 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20146 * data.c: Avoid integer truncation in expressions involving floats.
20147 * data.c: Include <intprops.h>.
20148 (arith_driver): When there's an integer overflow in an expression
20149 involving floating point, convert the integers to floating point
20150 so that the resulting value does not suffer from catastrophic
20151 integer truncation. For example, on a 64-bit host (* 4
20152 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20153 Do not rely on undefined behavior after integer overflow.
20155 merge count_size_as_multibyte, parse_str_to_multibyte
20156 * character.c, character.h (count_size_as_multibyte):
20157 Rename from parse_str_to_multibyte; all uses changed.
20158 Check for integer overflow.
20159 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20160 since it's now a duplicate of the other. This is more of
20161 a character than a buffer op, so better that it's in character.c.
20162 * fns.c, print.c: Adjust to above changes.
20164 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20166 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20168 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20170 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20171 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20172 (x_clipboard_manager_save): Now static.
20173 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20175 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20176 (crypto_hash_function): Now static.
20177 Fix pointer signedness problems. Avoid unnecessary initializations.
20179 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20181 * termhooks.h (Vselection_alist): Make it terminal-local.
20183 * terminal.c (create_terminal): Initialize it.
20185 * xselect.c: Support for clipboard managers.
20186 (Vselection_alist): Move to termhooks.h as terminal-local var.
20187 (LOCAL_SELECTION): New macro.
20188 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20189 (symbol_to_x_atom): Remove gratuitous arg.
20190 (x_handle_selection_request, lisp_data_to_selection_data)
20191 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20192 (x_own_selection, x_get_local_selection, x_convert_selection):
20193 New arg, specifying work frame. Use terminal-local Vselection_alist.
20194 (some_frame_on_display): Delete unused function.
20195 (Fx_own_selection_internal, Fx_get_selection_internal)
20196 (Fx_disown_selection_internal, Fx_selection_owner_p)
20197 (Fx_selection_exists_p): New optional frame arg.
20198 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20199 (x_handle_selection_clear): Don't treat other terminals with the
20200 same keyboard specially. Use the terminal-local Vselection_alist.
20201 (x_clear_frame_selections): Use Frun_hook_with_args.
20203 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20205 * xterm.h: Add support for those atoms.
20207 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20209 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20210 (converted_selections, conversion_fail_tag): New global variables.
20211 (x_selection_request_lisp_error): Free the above.
20212 (x_get_local_selection): Remove unnecessary code.
20213 (x_reply_selection_request): Args changed; handle arbitrary array
20214 of converted selections stored in converted_selections.
20215 Separate the XChangeProperty and SelectionNotify steps.
20216 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20217 (x_convert_selection): New function.
20218 (x_handle_selection_event): Simplify.
20219 (x_get_foreign_selection): Don't ignore incoming requests while
20220 waiting for an answer; this will fail when we implement
20221 SAVE_TARGETS, and seems unnecessary anyway.
20222 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20223 (Vx_sent_selection_functions): Doc fix.
20225 2011-05-26 Leo Liu <sdl.web@gmail.com>
20227 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20229 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20231 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20233 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20234 for fringe update if it has periodic bitmap.
20235 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20236 and fringe_bitmap_periodic_p.
20238 * fringe.c (get_fringe_bitmap_data): New function.
20239 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20240 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20241 row. Mark glyph row for fringe update if periodicity changed.
20243 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20244 for fringe update unless it has periodic bitmap.
20246 2011-05-25 Kenichi Handa <handa@m17n.org>
20248 * xdisp.c (get_next_display_element): Set correct it->face_id for
20249 a static composition.
20251 2011-05-24 Leo Liu <sdl.web@gmail.com>
20254 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20256 * fns.c (crypto_hash_function, Fsha1): New function.
20257 (Fmd5): Use crypto_hash_function.
20258 (syms_of_fns): Add Ssha1.
20260 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20262 * gnutls.c: Remove unused macros.
20263 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20264 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20265 Remove macros that are defined and never used.
20266 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20268 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20270 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20271 (Fx_get_selection_internal): Minor cleanup.
20272 (Fx_own_selection_internal): Rename arguments for consistency with
20275 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20277 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20279 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20281 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20283 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20285 * dispnew.c (scrolling_window): Don't exclude the case that the
20286 last enabled row in the desired matrix touches the bottom boundary.
20288 2011-05-21 Glenn Morris <rgm@gnu.org>
20290 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20291 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20292 and add some more files.
20294 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20296 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20297 report_file_error introduced by the change from 2011-05-07.
20299 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20301 * systime.h (Time): Define only if emacs is defined.
20302 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20303 where the include path doesn't have X11/X.h by default. See
20304 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20306 2011-05-20 Kenichi Handa <handa@m17n.org>
20308 * composite.c (find_automatic_composition): Fix previous change.
20310 2011-05-20 Glenn Morris <rgm@gnu.org>
20312 * lisp.mk: New file, split from Makefile.in.
20313 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20314 (shortlisp): Remove.
20315 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20317 2011-05-19 Glenn Morris <rgm@gnu.org>
20319 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20320 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20321 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20322 (lisp): Set the order to that of loadup.el.
20323 (shortlisp): Make it a copy of $lisp.
20324 (SOME_MACHINE_LISP): Remove.
20325 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20326 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20328 2011-05-18 Kenichi Handa <handa@m17n.org>
20330 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20331 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20332 (find_automatic_composition): Mostly rewrite for efficiency.
20334 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20336 * makefile.w32-in: Update dependencies.
20338 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20340 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20341 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20343 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20345 Fix some integer overflow issues, such as string length overflow.
20347 * insdel.c (count_size_as_multibyte): Check for string overflow.
20349 * character.c (lisp_string_width): Check for string overflow.
20350 Use EMACS_INT, not int, for string indexes and lengths; in
20351 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20352 the resulting string length overflows an EMACS_INT; instead,
20353 report a string overflow if no precision given. When checking for
20354 precision exhaustion, use a check that cannot possibly have
20355 integer overflow. (Bug#8675)
20356 * character.h (lisp_string_width): Adjust to new signature.
20358 * alloc.c (string_overflow): New function.
20359 (Fmake_string): Use it. This doesn't change behavior, but saves
20360 a few bytes and will simplify future changes.
20361 * character.c (string_escape_byte8): Likewise.
20362 * lisp.h (string_overflow): New decl.
20364 Fixups, following up to the user-interface timestamp change.
20365 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20366 for UI timestamps, instead of unsigned long.
20367 * msdos.c (mouse_get_pos): Likewise.
20368 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20369 * w32gui.h (Time): Define by including "systime.h" rather than by
20370 declaring it ourselves. (Bug#8664)
20372 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20373 * image.c (clear_image_cache): Likewise.
20375 * term.c (term_mouse_position): Don't assume time_t wraparound.
20377 Be more systematic about user-interface timestamps.
20378 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20379 and sometimes 'EMACS_UINT', to represent these timestamps.
20380 This change causes it to use 'Time' uniformly, as that's what X uses.
20381 This makes the code easier to follow, and makes it easier to catch
20382 integer overflow bugs such as Bug#8664.
20383 * frame.c (Fmouse_position, Fmouse_pixel_position):
20384 Use Time, not unsigned long, for user-interface timestamps.
20385 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20386 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20387 * keyboard.h (last_event_timestamp): Likewise.
20388 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20389 * menu.h (xmenu_show): Likewise.
20390 * term.c (term_mouse_position): Likewise.
20391 * termhooks.h (struct input_event.timestamp): Likewise.
20392 (struct terminal.mouse_position_hook): Likewise.
20393 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20394 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20395 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20396 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20397 what it was before.
20398 * menu.h, termhooks.h: Include "systime.h", for Time.
20400 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20401 Don't assume that the difference between two unsigned long values
20402 can fit into an integer. At this point, we know button_down_time
20403 <= event->timestamp, so the difference must be nonnegative, so
20404 there's no need to cast the result if double-click-time is
20405 nonnegative, as it should be; check that it's nonnegative, just in
20406 case. This bug is triggered when events are more than 2**31 ms
20407 apart (about 25 days). (Bug#8664)
20409 * xselect.c (last_event_timestamp): Remove duplicate decl.
20410 (x_own_selection): Remove needless cast to unsigned long.
20412 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20413 that always fit in int. Use a sentinel instead of a counter, to
20414 avoid a temp and to allay GCC's concerns about possible int overflow.
20415 * frame.h (struct frame): Use int for menu_bar_items_used
20416 instead of EMACS_INT, since it always fits in int.
20418 * menu.c (grow_menu_items): Check for int overflow.
20420 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20422 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20423 Before, the code was not consistent. These values cannot exceed
20424 2**31 - 1 so there's no need to make them unsigned.
20425 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20426 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20427 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20429 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20431 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20432 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20433 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20434 presumably because the widths might not match.
20436 * window.c (size_window): Avoid needless test at loop start.
20438 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20440 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20442 2011-05-12 Drew Adams <drew.adams@oracle.com>
20444 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20446 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20448 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20449 `width' to `bar_area_x' and `bar_area_width', respectively.
20450 (x_scroll_run): Take account of fringe background extension.
20452 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20453 Rename local vars `left' and `width' to `bar_area_x' and
20454 `bar_area_width', respectively.
20455 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20456 background extension.
20458 2011-05-10 Jim Meyering <meyering@redhat.com>
20460 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20462 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20464 * image.c (Finit_image_library): Return t for built-in image types,
20465 like pbm and xbm. (Bug#8640)
20467 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20469 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20471 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20473 * w32console.c (Fset_screen_color): Doc fix.
20474 (Fget_screen_color): New function.
20475 (syms_of_ntterm): Defsubr it.
20477 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20478 unlink the temporary file if Fcall_process didn't create it in the
20480 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20481 child process will be redirected to a file specified with `:file'.
20482 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20483 cue to call_process_cleanup not to close that handle.
20485 2011-05-07 Ben Key <bkey76@gmail.com>
20487 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20488 one of two shell specific rules, either bootstrap-temacs-CMD or
20489 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20490 to the previous implementation of the bootstrap-temacs rule.
20491 The bootstrap-temacs-CMD rule is similar to the previous
20492 implementation of the bootstrap-temacs rule except that it
20493 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20496 These changes, along with some changes to nt/configure.bat,
20497 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20498 earlier fix to add support for --cflags and --ldflags options
20499 that include quotes so that it works whether make uses cmd or
20502 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20504 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20505 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20507 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20508 a string. Handle both cases.
20509 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20510 (Fdbus_register_method): Use Qinvalid_function.
20512 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20514 * makefile.w32-in: Update dependencies.
20515 (LISP_H): Add inttypes.h and stdin.h.
20516 (PROCESS_H): Add unistd.h.
20518 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20520 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20521 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20523 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20525 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20527 * term.c (vfatal): Remove stray call to va_end.
20528 It's not needed and the C Standard doesn't allow it here anyway.
20530 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20531 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20533 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20536 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20538 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20540 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20542 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20544 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20546 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20547 * charset.c (Fdefine_charset_internal): Don't initialize
20548 charset.code_space[15]. The value was garbage, on hosts with
20549 32-bit int (Bug#8600).
20551 * lread.c (read_integer): Be more consistent with string-to-number.
20552 Use string_to_number to do the actual conversion; this avoids
20553 rounding errors and fixes some other screwups. Without this fix,
20554 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20555 (digit_to_number): Move earlier, for benefit of read_integer.
20556 Return -1 if the digit is out of range for the base, -2 if it is
20557 not a digit in any supported base. (Bug#8602)
20559 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20561 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20562 to match comment at start of function. This also removes a
20563 GCC warning about overflow in a 32+64-bit port.
20565 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20567 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20568 Reported by Stefan Monnier in
20569 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20570 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20571 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20573 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20574 (EMACS_UINTPTR): Likewise, with uintptr_t.
20576 * lisp.h: Prefer 64-bit EMACS_INT if available.
20577 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20578 on 32-bit hosts that have 64-bit int, so that they can access
20580 However, temporarily disable this change unless the temporary
20581 symbol WIDE_EMACS_INT is defined.
20583 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20585 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20586 This removes an assumption that EMACS_INT and long are the same
20587 width as pointers. The assumption is true for Emacs porting targets
20588 now, but we want to make other targets possible.
20589 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20590 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20591 In the rest of the code, change types of integers that hold casted
20592 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20593 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20594 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20595 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20596 No need to cast type when ORing.
20597 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20598 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20599 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20600 assume EMACS_INT is the same width as char *.
20601 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20602 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20603 Remove no-longer-needed casts.
20604 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20605 (xg_tool_bar_help_callback, xg_make_tool_item):
20606 Use EMACS_INTPTR to hold an integer
20607 that will be cast to void *; this can avoid a GCC warning
20608 if EMACS_INT is not the same width as void *.
20609 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20610 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20611 (current_message_1, set_message_1):
20612 Use a local to convert to proper width without a cast.
20613 * xmenu.c (dialog_selection_callback): Likewise.
20615 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20616 Also, don't assume VALBITS / RAND_BITS is less than 5,
20617 and don't rely on undefined behavior when shifting a 1 left into
20619 * lisp.h (get_random): Change signature to match.
20621 * lread.c (hash_string): Use size_t, not int, for hash computation.
20622 Normally we prefer signed values; but hashing is special, because
20623 it's better to use unsigned division on hash table sizes so that
20624 the remainder is nonnegative. Also, size_t is the natural width
20625 for hashing into memory. The previous code used 'int', which doesn't
20626 retain enough info to hash well into very large tables.
20627 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20629 * dbusbind.c: Don't possibly lose pointer info when converting.
20630 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20631 Use XPNTR rather than XHASH, so that the high-order bits of
20632 the pointer aren't lost when converting through void *.
20634 * eval.c (Fautoload): Don't double-shift a pointer.
20636 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20638 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20640 * gnutls.c (DEF_GNUTLS_FN):
20641 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20643 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20645 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20648 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20650 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20651 New version that can reserve upto 2GB of heap space.
20653 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20655 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20657 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20659 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20660 `gnutls_certificate_set_x509_key_file'.
20662 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20664 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20665 Update dependencies.
20667 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20669 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20670 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20671 Remove unused parameter `fildes'.
20672 * process.c (read_process_output, send_process): Don't pass it.
20674 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20676 Fix previous change: the library cache is defined in w32.c.
20677 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20678 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20680 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20682 Implement dynamic loading of GnuTLS on Windows.
20684 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20685 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20686 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20689 * gnutls.c (Qgnutls_dll): Define.
20690 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
20691 (gnutls_*): Declare function pointers.
20692 (init_gnutls_functions): New function to initialize function pointers.
20693 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
20694 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
20695 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20696 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
20697 (emacs_gnutls_write, emacs_gnutls_read)
20698 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20699 (Fgnutls_available_p): New function.
20700 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
20701 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
20702 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
20704 * image.c: Include w32.h.
20705 (Vimage_type_cache): Delete.
20706 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
20707 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
20708 (w32_delayed_load): Move to w32.c.
20710 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20712 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20713 (w32_delayed_load): Move from image.c. When loading a library, record
20714 its filename in the :loaded-from property of the library id.
20715 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20716 Initialize and staticpro them.
20717 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20719 * process.c: Include lisp.h before w32.h, not after.
20720 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20721 instead of gnutls_record_check_pending.
20723 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20725 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20727 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20728 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20731 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20733 * xterm.c (x_set_frame_alpha): Do not set property on anything
20734 else than FRAME_X_OUTER_WINDOW (Bug#8608).
20736 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20738 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
20740 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20742 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
20743 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

20749 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
20750 (Qgnutls_bootprop_callbacks_verify): Make static.
20752 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
20754 * callproc.c: Indentation fixup.
20756 * sysdep.c (wait_for_termination_1): Make static.
20757 (wait_for_termination, interruptible_wait_for_termination):
20758 Move after wait_for_termination_1.
20760 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
20762 * sysdep.c (interruptible_wait_for_termination): New function
20763 which is like wait_for_termination, but allows keyboard
20766 * callproc.c (Fcall_process): Add (:file "file") as an option for
20768 (Fcall_process_region): Ditto.
20770 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20772 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20773 rather than `XVECTOR (FOO)->size'.
20775 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20776 inttypes.h, as a gnulib replacement is used if it not available in
20779 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20781 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20782 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20783 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20785 * coding.c (coding_alloc_by_realloc): Error out if destination
20786 will grow beyond MOST_POSITIVE_FIXNUM.
20787 (decode_coding_emacs_mule): Abort if there isn't enough place in
20788 charbuf for the composition carryover bytes. Reserve an extra
20789 space for up to 2 characters produced in a loop.
20790 (decode_coding_iso_2022): Abort if there isn't enough place in
20791 charbuf for the composition carryover bytes.
20793 2011-04-21 Eli Zaretskii <eliz@gnu.org>

20796 aborting when %lld or %lll format is passed.
20797 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20798 %llo or %llx format is passed. (Bug#8545)
20800 * window.c (window_scroll_line_based): Use a marker instead of
20801 simple variables to record original value of point. (Bug#7952)
20803 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20804 produced by %s or %c overflows available buffer space. (Bug#8545)
20806 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20808 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20809 (SIZE_MAX): Move defn after all includes, as they might #define it.
20811 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20813 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20815 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

20819 if Vdelayed_warnings_list is non-nil.
20820 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20821 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20823 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20825 * doprnt.c (doprnt): Don't return value smaller than the buffer
20826 size if the message was truncated. (Bug#8545).
20828 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20830 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20831 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20833 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20835 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20837 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20839 * makefile.w32-in: Update dependencies.
20841 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20843 Improve `doprnt' and its usage. (Bug#8545)
20844 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20845 `format_end'. Remove support for %l as a conversion specifier.
20846 Don't use xrealloc. Improve diagnostics when the %l size modifier
20847 is used. Update the commentary.
20849 * eval.c (verror): Simplify calculation of size_t.
20851 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20854 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20856 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20859 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20861 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20862 This makes this file independent of the recent pseudovector change.
20864 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20866 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20868 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20869 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20870 Remove unused local.
20871 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20873 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20874 GCC 4.6.0 optimizes based on type-based alias analysis.
20875 For example, if b is of type struct buffer * and v of type struct
20876 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20877 != &v->size, and therefore "v->size = 1; b->size = 2; return
20878 v->size;" must therefore return 1. This assumption is incorrect
20879 for Emacs, since it type-puns struct Lisp_Vector * with many other
20880 types. To fix this problem, this patch adds a new type struct
20881 vectorlike_header that documents the constraints on layout of vectors
20882 and pseudovectors, and helps optimizing compilers not get fooled
20883 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20884 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20885 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20887 (XSETPVECTYPE): Rewrite in terms of new macro.
20888 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20889 This is a bit clearer, and further avoids the possibility of
20890 undesirable aliasing.
20891 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20892 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20893 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20894 since Lisp_Subr is a special case (no "next" field).
20895 (ASIZE): Now uses header.size rather than size.
20896 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20897 to avoid the hassle of writing XVECTOR (foo)->header.size.
20898 (struct vectorlike_header): New type.
20899 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20900 object, to help avoid aliasing.
20901 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20902 (SUBRP): Likewise, since Lisp_Subr is a special case.
20903 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20904 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20905 (struct Lisp_Hash_Table): Combine first two members into a single
20906 struct vectorlike_header member. All uses of "size" and "next" members
20907 changed to be "header.size" and "header.next".
20908 * buffer.h (struct buffer): Likewise.
20909 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20910 * frame.h (struct frame): Likewise.
20911 * process.h (struct Lisp_Process): Likewise.
20912 * termhooks.h (struct terminal): Likewise.
20913 * window.c (struct save_window_data, struct saved_window): Likewise.
20914 * window.h (struct window): Likewise.
20915 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20916 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20917 * buffer.c (init_buffer_once): Likewise.
20918 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20920 * process.c (Fformat_network_address): Use local var for size,
20923 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20925 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20926 * data.c (atof): Remove decl; no longer used or needed.
20927 (digit_to_number): Move to lread.c.
20928 (Fstring_to_number): Use new string_to_number function, to be
20929 consistent with how the Lisp reader treats infinities and NaNs.
20930 Do not assume that floating-point numbers represent EMACS_INT
20931 without losing information; this is not true on most 64-bit hosts.
20932 Avoid double-rounding errors, by insisting on integers when
20933 parsing non-base-10 numbers, as the documentation specifies.
20934 * lisp.h (string_to_number): New decl, replacing ...
20935 (isfloat_string): Remove.
20936 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20937 (read1): Do not accept +. and -. as integers; this
20938 appears to have been a coding error. Similarly, do not accept
20939 strings like +-1e0 as floating point numbers. Do not report
20940 overflow for integer overflows unless the base is not 10 which
20941 means we have no simple and reliable way to continue.
20942 Break out the floating-point parsing into a new
20943 function string_to_number, so that Fstring_to_number parses
20944 floating point numbers consistently with the Lisp reader.
20945 (digit_to_number): Move here from data.c. Make it static inline.
20946 (E_CHAR, EXP_INT): Remove, replacing with ...
20947 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20948 (string_to_number): New function, replacing isfloat_string.
20949 This function checks for valid syntax and produces the resulting
20950 Lisp float number too. Rework it so that string-to-number
20951 no longer mishandles examples like "1.0e+". Use strtoumax,
20952 so that overflow for non-base-10 numbers is reported only when
20953 there's no portable and simple way to convert to floating point.
20955 * textprop.c (set_text_properties_1): Rewrite for clarity,
20956 and to avoid GCC warning about integer overflow.
20958 * intervals.h (struct interval): Use EMACS_INT for members
20959 where EMACS_UINT might cause problems. See
20960 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20961 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20962 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20964 (offset_intervals): Tell GCC not to worry about length overflow
20965 when negating a negative length.
20967 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20968 (overrun_check_free): Likewise.
20970 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20971 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20974 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20975 (gnutls_make_error): Rename local to avoid shadowing.
20976 (gnutls_emacs_global_deinit): ifdef out; not used.
20977 (Fgnutls_boot): Use const for pointer to readonly storage.
20978 Comment out unused local. Fix pointer signedness problems.
20980 * lread.c (openp): Don't stuff size_t into an 'int'.
20981 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20982 about possible signed overflow.
20984 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20985 (GDK_KEY_g): Don't define if already defined.
20986 (xg_prepare_tooltip): Avoid pointer signedness problem.
20987 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20989 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20990 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20992 * xfns.c (Fx_window_property): Simplify a bit,
20993 to make a bit faster and to avoid GCC 4.6.0 warning.
20994 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20996 * fns.c (internal_equal): Don't assume size_t fits in int.
20998 * alloc.c (compact_small_strings): Tighten assertion a little.
21000 Replace pEd with more-general pI, and fix some printf arg casts.
21001 * lisp.h (pI): New macro, generalizing old pEd macro to other
21002 conversion specifiers. For example, use "...%"pI"d..." rather
21003 than "...%"pEd"...".
21004 (pEd): Remove. All uses replaced with similar uses of pI.
21005 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21006 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21007 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21008 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21009 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21010 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21011 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21013 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21014 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21015 * print.c (safe_debug_print, print_object): Likewise.
21016 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21018 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21019 avoiding the 0 flag, which is not portable.
21020 * process.c (Fmake_network_process): Use pI to avoid cast.
21021 * region-cache.c (pp_cache): Likewise.
21022 * xdisp.c (decode_mode_spec): Likewise.
21023 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21024 behavior on 64-bit hosts with printf arg.
21025 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21026 (x_stop_queuing_selection_requests): Likewise.
21027 (x_get_window_property): Don't truncate byte count to an 'int'
21030 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21031 here, since it parses constructs like leading '-' and spaces,
21032 which are not wanted; and it overflows with large numbers.
21033 Instead, simply match F[0-9]+, which is what is wanted anyway.
21035 * alloc.c: Remove unportable assumptions about struct layout.
21036 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21037 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21038 (allocate_vectorlike, make_pure_vector): Use the new macros,
21039 plus offsetof, to remove unportable assumptions about struct layout.
21040 These assumptions hold on all porting targets that I know of, but
21041 they are not guaranteed, they're easy to remove, and removing them
21042 makes further changes easier.
21044 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21045 This doesn't fix a bug but makes the code clearer.
21046 (string_overrun_cookie): Now const. Use initializers that
21047 don't formally overflow signed char, to avoid warnings.
21048 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21049 can cause Emacs to crash when string overrun checking is enabled.
21050 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21051 multiple of sizeof (EMACS_INT); it need not be, if
21052 alignof(EMACS_INT) < sizeof (EMACS_INT).
21053 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21055 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

21059 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
21061 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
21062 supposed to be handshaking. (Bug#8556)
21063 Reported by Paul Eggert <eggert@cs.ucla.edu>.
21065 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
21067 * lisp.h (Qdebug): List symbol.
21068 * eval.c (Qdebug): Restore global linkage.

21070 (handle_user_signal): Break into debugger when debug-on-event
21071 matches the current signal symbol.
21073 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
21075 * alloc.c (check_sblock, check_string_bytes)
21076 (check_string_free_list): Convert to standard C.
21078 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
21080 * w32.c (emacs_gnutls_push): Fix typo.
21082 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21084 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21085 "cast to pointer from integer of different size".
21087 Improve doprnt and its use in verror. (Bug#8545)
21088 * doprnt.c (doprnt): Document the set of format control sequences
21089 supported by the function. Use SAFE_ALLOCA instead of always
21092 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21093 is one byte too soon. Don't use xrealloc; instead xfree and
21096 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21098 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21101 * gnutls.c: Renamed global_initialized to
21102 gnutls_global_initialized. Added internals for the
21103 :verify-hostname-error, :verify-error, and :verify-flags
21104 parameters of `gnutls-boot' and documented those parameters in the
21105 docstring. Start callback support.
21106 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21107 unless a fatal error occurred. Call gnutls_alert_send_appropriate
21108 on error. Return error code.
21109 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
21110 (emacs_gnutls_read): Likewise.
21111 (Fgnutls_boot): Return handshake error code.
21112 (emacs_gnutls_handle_error): New function.
21113 (wsaerror_to_errno): Likewise.

21175 <char-direction-table>: Deleted.
21177 2011-04-23 Eli Zaretskii <eliz@gnu.org>
21179 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
21180 * doprnt.c: Include limits.h.
21181 (SIZE_MAX): New macro.
21182 (doprnt): Return a size_t value. 2nd arg is now size_t.
21183 Many local variables are now size_t instead of int or unsigned.
21184 Improve overflow protection. Support `l' modifier for integer
21185 conversions. Support %l conversion. Don't assume an EMACS_INT
21186 argument for integer conversions and for %c.
21188 * lisp.h (doprnt): Restore prototype.
21190 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
21191 $(SRC)/character.h.
21193 * Makefile.in (base_obj): Add back doprnt.o.
21195 * deps.mk (doprnt.o): Add back prerequisites.
21196 (callint.o): Depend on character.h.
21198 * eval.c (internal_lisp_condition_case): Include the handler
21199 representation in the error message.
21200 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
21201 when breaking from the loop.
21203 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
21205 * callint.c (Fcall_interactively): When displaying error message
21206 about invalid control letter, pass the character's codepoint, not
21207 a pointer to its multibyte form. Improve display of the character
21208 in octal and display also its hex code.
21210 * character.c (char_string): Use %x to display the (unsigned)
21211 codepoint of an invalid character, to avoid displaying a bogus
21214 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21215 `error', not SYMBOL_NAME itself.
21217 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
21218 character arguments to `error'.
21220 * charset.c (check_iso_charset_parameter): Fix incorrect argument
21221 to `error' in error message about FINAL_CHAR argument. Make sure
21222 FINAL_CHAR is a character, and use %c when it is passed as
21223 argument to `error'.

21287 Define only if needed.
21289 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
21290 by pacifying GCC about it. Maybe it's time to retire it?
21291 * xfaces.c (USG, __TIMEVAL__): Likewise.
21293 * dispextern.h (struct redisplay_interface): Rename param
21294 to avoid shadowing.

21342 compatible char. Avoid the old compiler warnings about
21343 out-of-range initializers by using, for example, '\xab' rather
21346 * xgselect.c (xgselect_initialize): Check vs interface
21347 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

21412 * nsfont.m: Fixed bugs in ns_get_family and
21413 ns_descriptor_to_entity that were caused by using free to
21414 deallocate memory blocks that were allocated by xmalloc (via
21415 xstrdup). This caused Emacs to crash when compiled with
21416 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
21417 --enable-checking=xmallocoverrun). xfree is now used to
21418 deallocate these memory blocks.

21432 (emacs_read, emacs_write): Remove check for negative size, as the
21433 Emacs source code has been audited now.
21434 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
21435 (emacs_read, emacs_write): Use it.
21436 * process.c (send_process): Adjust to the new signatures of
21437 emacs_write and emacs_gnutls_write. Do not attempt to store
21438 a byte offset into an 'int'; it might overflow.
21439 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

21773 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
21774 * dispextern.h (bidi_dump_cached_states): Remove, since it's
21775 exported only to the debugger.
21777 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
21778 * atimer.h (run_all_atimers): Remove; not exported.
21780 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
21781 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
21782 was inaccessible from Lisp.
21783 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
21784 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
21786 alloc.c: Import and export fewer symbols, and remove unused items.
21787 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
21789 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
21790 it's not optimized away by whole-program optimization.

21803 (mark_backtrace): Define only if BYTE_MARK_STACK.
21804 * xdisp.c (message_enable_multibyte): Now static.
21806 Declare Lisp_Object Q* variables to be 'static' if not exported.
21807 This makes it easier for human readers (and static analyzers)
21808 to see whether these variables are used from other modules.
21809 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

21820 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21822 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21824 Make Emacs functions such as Fatom 'static' by default.
21825 This makes it easier for human readers (and static analyzers)
21826 to see whether these functions can be called from other modules.
21827 DEFUN now defines a static function. To make the function external
21828 so that it can be used in other C modules, use the new macro DEFUE.

21834 Remove decls, since these functions are now static.
21835 (Funintern, Fget_internal_run_time): New decls, since these functions
21836 were already external.

21846 Mark functions with DEFUE instead of DEFUN,
21847 if they are used in other modules.

21849 decls for now-static functions.
21850 * buffer.h (Fdelete_overlay): Remove decl.

21886 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21888 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21889 when at ZV. (Bug#8487)
21891 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>

21899 * xsettings.c (read_and_apply_settings): Likewise.
21901 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21902 (overrun_check_free): Protoize.
21904 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21906 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21907 since callers should never pass a negative size.
21908 Change the signature to match that of plain 'read' and 'write'; see
21909 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21910 * lisp.h: Update prototypes of emacs_write and emacs_read.
21912 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21914 * xdisp.c (redisplay_window): Don't try to determine the character
21915 position of the scroll margin if the window start point w->startp
21916 is outside the buffer's accessible region. (Bug#8468)
21918 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21920 Fix write-region and its subroutines for buffers > 2GB.
21921 * fileio.c (a_write, e_write): Modify declaration of arguments and
21922 local variables to support buffers larger than 2GB.
21923 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21925 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21926 argument, local variables, and return value.
21928 * lisp.h: Update prototypes of emacs_write and emacs_read.
21930 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21932 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21934 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21936 Fix more problems found by GCC 4.6.0's static checks.
21938 * xdisp.c (vmessage): Use a better test for character truncation.
21940 * charset.c (load_charset_map): <, not <=, for optimization,
21941 and to avoid potential problems with integer overflow.
21942 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21943 * casetab.c (set_identity, shuffle): Likewise.
21944 * editfns.c (Fformat): Likewise.
21945 * syntax.c (skip_chars): Likewise.
21947 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21948 This also lets GCC 4.6.0 generate slightly better loop code.
21950 * callint.c (Fcall_interactively): <, not <=, for optimization.
21951 (Fcall_interactively): Count the number of arguments produced,
21952 not the number of arguments given. This is simpler and lets GCC
21953 4.6.0 generate slightly better code.
21955 * ftfont.c: Distingish more carefully between FcChar8 and char.
21956 The previous code passed unsigned char * to a functions like
21957 strlen and xstrcasecmp that expect char *, which does not
21958 conform to the C standard.
21959 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21960 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21961 char * when the C standard requires it.
21963 * keyboard.c (read_char): Remove unused var.
21965 * eval.c: Port to Windows vsnprintf (Bug#8435).
21966 Include <limits.h>.
21967 (SIZE_MAX): Define if the headers do not.
21968 (verror): Do not give up if vsnprintf returns a negative count.
21969 Instead, grow the buffer. This ports to Windows vsnprintf, which
21970 does not conform to C99. Problem reported by Eli Zaretskii.
21971 Also, simplify the allocation scheme, by avoiding the need for
21972 calling realloc, and removing the ALLOCATED variable.
21974 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21976 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21977 But keep the doprint source code for now, as we might revamp it
21978 and use it again (Bug#8435).
21979 * lisp.h (doprnt): Remove.
21980 * Makefile.in (base_obj): Remove doprnt.o.
21981 * deps.mk (doprnt.o): Remove.
21983 error: Print 32- and 64-bit integers portably (Bug#8435).
21984 Without this change, on typical 64-bit hosts error ("...%d...", N)
21985 was used to print both 32- and 64-bit integers N, which relied on
21986 undefined behavior.
21987 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21988 * lisp.h (error, verror): Mark as printf-like functions.
21989 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21990 Report overflow in size calculations when allocating printf buffer.
21991 Do not truncate output string at its first null byte.
21992 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21993 Truncate the output at a character boundary, since vsnprintf does not
21995 * charset.c (check_iso_charset_parameter): Convert internal
21996 character to string before calling 'error', since %c now has the
21998 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21999 overflow when computing char to be passed to 'error'. Do not
22000 pass Lisp_Object to 'error'; pass the integer instead.
22001 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22002 formatted with plain %d.
22004 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22006 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22008 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22010 * xterm.c (x_catch_errors): Remove duplicate declaration.
22012 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22014 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22016 2011-04-10 Jim Meyering <meyering@redhat.com>
22018 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22019 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22020 return ssize_t not "int", and use size_t as the buffer length.
22021 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22022 * gnutls.h: Update declarations.
22023 * process.c (read_process_output): Use ssize_t, to match.
22024 (send_process): Likewise.
22026 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22028 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22030 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22032 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22033 Use unsigned char, to match FcChar8 type definition.
22035 * xterm.c (handle_one_xevent):
22036 * xmenu.c (create_and_show_popup_menu):
22037 * xselect.c (x_decline_selection_request)
22038 (x_reply_selection_request): Avoid type-punned deref of X events.
22040 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22042 Fix some uses of `int' instead of EMACS_INT.
22043 * search.c (string_match_1, fast_string_match)
22044 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22045 (scan_buffer, find_next_newline_no_quit)
22046 (find_before_next_newline, search_command, Freplace_match)
22047 (Fmatch_data): Make some `int' variables be EMACS_INT.
22049 * xdisp.c (display_count_lines): 3rd argument and return value now
22050 EMACS_INT. All callers changed.
22051 (pint2hrstr): Last argument is now EMACS_INT.
22053 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22054 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22055 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

22066 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22067 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22069 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22070 (encode_invocation_designation): Last argument P_NCHARS is now
22072 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22073 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22075 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22078 * ccl.c (Fccl_execute_on_string): Declare some variables
22081 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22083 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22085 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22087 * process.c (Fformat_network_address): Doc fix.
22089 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22091 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22093 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22095 * keyboard.c (read_char): Call Lisp function help-form-show,
22096 instead of using internal_with_output_to_temp_buffer.
22097 (Qhelp_form_show): New var.
22098 (syms_of_keyboard): Use DEFSYM macro.
22100 * print.c (internal_with_output_to_temp_buffer): Function deleted.

22107 (list_processes_1): Delete.
22109 2011-04-06 Eli Zaretskii <eliz@gnu.org>
22111 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22113 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22115 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22117 Fix more problems found by GCC 4.6.0's static checks.

22138 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22139 This avoids several warnings with gcc -Wstrict-overflow.
22140 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22141 directly, rather than having caller test rule sign. This avoids
22142 some unnecessary tests.
22143 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22144 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22145 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22147 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22148 (xfont_open): Avoid unnecessary tests.
22150 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22152 * composite.h, composite.c (composition_gstring_put_cache):
22153 Use EMACS_INT, not int, for length.
22155 * composite.h (COMPOSITION_DECODE_REFS): New macro,
22156 breaking out part of COMPOSITION_DECODE_RULE.
22157 (COMPOSITION_DECODE_RULE): Use it.
22158 * composite.c (get_composition_id): Remove unused local vars,
22159 by using the new macro.
22161 * textprop.c (set_text_properties_1): Change while to do-while,
22162 since the condition is always true at first.
22164 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22165 (interval_deletion_adjustment): Return unsigned value.
22168 * process.c (list_processes_1, create_pty, read_process_output):
22169 (exec_sentinel): Remove vars that were set but not used.
22170 (create_pty): Remove unnecessary "volatile"s.
22171 (Fnetwork_interface_info): Avoid possibility of int overflow.
22172 (read_process_output): Do adaptive read buffering even if carryover.

22184 * print.c (print_error_message): Avoid int overflow.
22186 * font.c (font_list_entities): Redo for clarity,
22187 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22189 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22190 (font_score): Avoid potential overflow in diff calculation.

22193 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22195 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22197 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22198 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22199 can always succeed if overflow has undefined behavior.
22201 * search.c (boyer_moore, wordify): Remove vars set but not used.
22202 (wordify): Omit three unnecessary tests.
22204 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22205 All callers changed. This avoids the need for an unused var.
22207 * casefiddle.c (casify_region): Remove var that is set but not used.
22209 * dired.c (file_name_completion): Remove var that is set but not used.
22211 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22213 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22214 (Finsert_file_contents): Remove unnecessary code checking fd.
22216 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22217 Check for integer overflow on size calculations.
22219 * buffer.c (Fprevious_overlay_change): Remove var that is set
22222 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22223 Remove vars that are set but not used.
22224 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22225 (timer_check_2): Mark vars as initialized.
22227 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22229 * image.c (lookup_image): Remove var that is set but not used.
22230 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22232 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22233 that are set but not used.
22235 * xfns.c (make_invisible_cursor): Don't return garbage
22236 if XCreateBitmapFromData fails (Bug#8410).
22238 * xselect.c (x_get_local_selection, x_handle_property_notify):
22239 Remove vars that are set but not used.
22241 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
22242 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
22244 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
22245 Remove var that is set but not used.
22246 (scroll_bar_windows_size): Now size_t, not int.
22247 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
22248 Check for overflow.
22250 * xfaces.c (realize_named_face): Remove vars that are set but not used.
22251 (map_tty_color) [!defined MSDOS]: Likewise.
22253 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22255 * coding.c: Remove vars that are set but not used.
22256 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22257 All callers changed.
22258 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22259 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22260 (decode_coding_charset): Remove vars that are set but not used.
22262 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22263 that is set but not used.
22265 * print.c (print_object): Remove var that is set but not used.
22267 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22268 The gnulib version avoids calling malloc in the usual case,
22269 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22270 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22271 * filelock.c (current_lock_owner): Likewise.
22272 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22273 * sysdep.c: Include allocator.h, careadlinkat.h.
22274 (emacs_no_realloc_allocator): New static constant.
22275 (emacs_readlink): New function.
22276 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22277 ../lib/careadlinkat.h.
22279 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22281 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22282 first non-nil return value).
22284 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
22286 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
22287 if not defined (Bug#8403).
22289 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22291 * xdisp.c (display_count_lines): Remove parameter `start',
22292 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22293 (get_char_face_and_encoding): Remove parameter `multibyte_p',
22294 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

22296 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22297 and thereabouts. All callers changed.
22298 (get_per_char_metric): Remove parameter `f', unused since
22299 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
22301 2011-04-02 Jim Meyering <meyering@redhat.com>
22303 do not dereference NULL upon failed strdup
22304 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22305 (ns_get_family): Likewise.
22307 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22309 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
22311 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
22313 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
22316 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
22318 Add lexical binding.
22320 * window.c (Ftemp_output_buffer_show): New fun.
22321 (Fsave_window_excursion):
22322 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
22324 * lread.c (lisp_file_lexically_bound_p): New function.
22325 (Fload): Bind Qlexical_binding.
22326 (readevalloop): Remove `evalfun' arg.
22327 Bind Qinternal_interpreter_environment.
22328 (Feval_buffer): Bind Qlexical_binding.
22329 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
22331 (syms_of_lread): Declare `lexical-binding'.
22333 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22335 * keyboard.c (eval_dyn): New fun.
22336 (menu_item_eval_property): Use it.
22338 * image.c (parse_image_spec): Use Ffunctionp.
22340 * fns.c (concat, mapcar1): Accept byte-code-functions.
22342 * eval.c (Fsetq): Handle lexical vars.
22343 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22344 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22345 (FletX, Flet): Obey lexical binding.
22346 (Fcommandp): Handle closures.
22347 (Feval): New `lexical' arg.
22348 (eval_sub): New function extracted from Feval. Use it almost
22349 everywhere where Feval was used. Look up vars in lexical env.
22351 (Ffunctionp): Move from subr.el.
22352 (Ffuncall): Handle closures.
22353 (apply_lambda): Remove `eval_flags'.
22354 (funcall_lambda): Handle closures and new byte-code-functions.
22355 (Fspecial_variable_p): New function.
22356 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22357 but without exporting it to Lisp.
22359 * doc.c (Fdocumentation, store_function_docstring):
22360 * data.c (Finteractive_form): Handle closures.
22362 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22365 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22367 (exec_byte_code): New function extracted from Fbyte_code to handle new
22368 calling convention for byte-code-functions. Add new byte-codes.
22370 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22372 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22374 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22376 * xdisp.c (redisplay_internal): Fix prototype.
22378 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22380 * xdisp.c (SCROLL_LIMIT): New macro.
22381 (try_scrolling): Use it when setting scroll_limit.
22382 Limit scrolling to 100 screen lines.
22383 (redisplay_window): Even when falling back on "recentering",
22384 position point in the window according to scroll-conservatively,
22385 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22387 (try_scrolling): When point is above the window, allow searching
22388 as far as scroll_max, or one screenful, to compute vertical
22389 distance from PT to the scroll margin position. This prevents
22390 try_scrolling from unnecessarily failing when
22391 scroll-conservatively is set to a value slightly larger than the
22392 window height. Clean up the case of PT below the margin at bottom
22393 of window: scroll_max can no longer be INT_MAX. When aggressive
22394 scrolling is in use, don't let point enter the opposite scroll
22395 margin as result of the scroll.
22396 (syms_of_xdisp) <scroll-conservatively>: Document the
22397 threshold of 100 lines for never-recentering scrolling.
22399 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22401 * dispextern.h (move_it_by_lines):

22404 (message_log_check_duplicate): Remove parameters `prev_bol' and
22405 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22406 (redisplay_internal): Remove parameter `preserve_echo_area',
22407 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22409 * indent.c (Fvertical_motion):
22410 * window.c (window_scroll_pixel_based, Frecenter):
22411 Don't pass `need_y_p' to `move_it_by_lines'.
22413 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22415 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22416 steal a few bits to be more compact.
22417 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22418 Remove unneeded casts.
22420 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22422 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22424 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22425 binding" message (bug#7967).
22427 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22429 Fix more problems found by GCC 4.6.0's static checks.
22431 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22432 Remove unused local var.
22434 * editfns.c (Fmessage_box): Remove unused local var.
22436 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22437 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22438 Omit unused local vars.
22439 * window.c (shrink_windows): Omit unused local var.
22440 * menu.c (digest_single_submenu): Omit unused local var.
22441 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22442 Omit unused local var.
22444 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22445 Don't assume string length fits in int.
22446 (keyremap_step, read_key_sequence): Use size_t for sizes.
22447 (read_key_sequence): Don't check last_real_key_start redundantly.
22449 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22450 instead of alloca (Bug#8344).
22452 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22453 (Fbacktrace_frame): Don't assume nframes fits in int.
22455 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

22460 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22462 * cm.c (calccost): Turn while-do into do-while, for clarity.
22464 * keyboard.c (syms_of_keyboard): Use the same style as later
22465 in this function when indexing through an array. This also
22466 works around GCC bug 48267.
22468 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22470 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22472 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22473 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22475 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22476 This avoids undefined behavior on integer overflow, and is a bit
22477 more convenient anyway since it is compared to a size_t variable.
22479 Variadic C functions now count arguments with size_t, not int.
22480 This avoids an unnecessary limitation on 64-bit machines, which
22481 caused (substring ...) to crash on large vectors (Bug#8344).
22482 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22483 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

22491 * fns.c (concat): Likewise.
22492 * frame.c (x_set_frame_parameters): Likewise.
22493 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22494 0 if not found, not -1. All callers changed.
22496 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22497 (stack_copy_size): Now size_t, not int.
22498 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22500 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22502 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
22503 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22504 All callers changed.
22506 * lisp.h (multibyte_char_to_unibyte):
22507 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22508 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

22519 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22520 don't set the hook to nil, but remove the offending function instead.
22521 (Qcommand_hook_internal): Remove, unused.
22522 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22523 Vcommand_hook_internal.
22525 * eval.c (enum run_hooks_condition): Remove.
22526 (funcall_nil, funcall_not): New functions.
22527 (run_hook_with_args): Call each function through a `funcall' argument.

22541 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
22542 All callers changed.
22544 * w32.c (_wsa_errlist): Use braces for struct initializers.
22546 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
22547 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
22548 All callers changed.

22585 2011-03-26 Eli Zaretskii <eliz@gnu.org>
22587 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
22588 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
22590 2011-03-26 Juanma Barranquero <lekktu@gmail.com>

22693 * term.c (Fsuspend_tty, Fresume_tty):
22694 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22695 * window.c (temp_output_buffer_show):

22703 * buffer.c (Fkill_all_local_variables):
22704 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22706 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22707 unconditionally since it does the check itself.
22709 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22711 Fix more problems found by GCC 4.5.2's static checks.
22713 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22714 the first time through the loop, since we know p0 < p1 then.
22715 This also avoids a gcc -Wstrict-overflow warning.
22717 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22718 leading to a memory leak, possible in functions like
22719 load_charset_map_from_file that can allocate an unbounded number
22720 of objects (Bug#8318).
22722 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22723 that could (at least in theory) be that large.
22725 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22726 This is less likely to overflow, and avoids undefined behavior if
22727 overflow does occur. All callers changed. Use strtoul to scan
22728 for the unsigned long integer.
22729 (pint2hrstr): Simplify and tune code slightly.
22730 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

22740 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22743 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22745 * process.c (Fmake_network_process): Use socklen_t, not int,
22746 where POSIX says socklen_t is required in portable programs.
22747 This fixes a porting bug on hosts like 64-bit HP-UX, where
22748 socklen_t is wider than int (Bug#8277).
22749 (Fmake_network_process, server_accept_connection):
22750 (wait_reading_process_output, read_process_output):
22753 * process.c: Rename or move locals to avoid shadowing.

22763 Make tparam.h and terminfo.c consistent.
22764 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22765 Include tparam.h instead, since it declares them.
22766 * cm.h (PC): Remove extern decl; tparam.h now does this.
22767 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22768 * terminfo.c: Include tparam.h, to check interfaces.
22769 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22770 (tparam): Adjust signature to match interface in tparam.h;
22771 this removes some undefined behavior. Check that outstring and len
22772 are zero, which they always are with Emacs.
22773 * tparam.h (PC, BC, UP): New extern decls.
22775 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22776 (xftfont_open): Rename locals to avoid shadowing.
22778 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

22790 * composite.c (composition_compute_stop_pos): Rename local to
22792 (composition_reseat_it): Remove unused locals.
22793 (find_automatic_composition, composition_adjust_point): Likewise.
22794 (composition_update_it): Mark var as initialized.
22795 (find_automatic_composition): Mark vars as initialized,
22796 with a FIXME (Bug#8290).

22800 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22801 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22802 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22803 to avoid shadowing.
22805 * textprop.c (property_change_between_p): Remove; unused.
22807 * intervals.c (interval_start_pos): Now static.
22809 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

22815 Fix pointer signedness.
22816 (alsa_choose_format): Remove unused local var.
22817 (wav_play): Initialize a variable to 0, to prevent undefined
22818 behavior (Bug#8278).
22820 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22822 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22824 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22825 clobbering (Bug#8298).
22826 * sysdep.c (sys_subshell): Likewise.
22827 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22829 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22830 This should get cleaned up, so that child_setup has the
22831 same signature on all platforms.
22833 * callproc.c (call_process_cleanup): Now static.
22834 (relocate_fd): Rename locals to avoid shadowing.
22836 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22838 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22839 not to be necessary, and produces flickering.
22841 2011-03-20 Glenn Morris <rgm@gnu.org>
22843 * config.in: Remove file.
22845 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
22847 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
22848 are now in src/globals.h.
22849 (syms_of_minibuf): Remove spurious & from previous change.

22875 (sigchld_handler): Now static.
22877 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
22878 That way, the code declares only the vars that it needs.

22888 (CONSTANTLIM): Remove; unused.
22889 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
22890 Define only if needed.
22892 * unexelf.c (unexec): Name an expression,
22893 to avoid gcc -Wbad-function-cast warning.
22894 Use a different way to cause a compilation error if anyone uses
22895 n rather than nn, a way that does not involve shadowing.
22896 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22898 * deps.mk (unexalpha.o): Remove; unused.
22900 New file unexec.h, the (simple) interface for unexec (Bug#8267).

22966 (Fformat_time_string, Fencode_time, Finsert_char):
22967 (Ftranslate_region_internal, Fformat):
22968 Rename or remove local vars to avoid shadowing.
22969 (Ftranslate_region_internal): Mark var as initialized.
22971 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
22974 * lisp.h (eassert): Check that the argument compiles, even if
22975 ENABLE_CHECKING is not defined.
22977 * data.c (Findirect_variable): Name an expression, to avoid
22978 gcc -Wbad-function-cast warning.

22995 (Fmemory_limit): Cast sbrk's returned value to char *.
22997 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

23021 (RETALLOC_IF): Define only if needed.
23022 (WORDCHAR_P): Likewise. This one is never needed, but is used
23023 only in a comment talking about a compiler bug, so put inside
23024 the #if 0 of that comment.

23053 New macros, so that the caller can use some names other than
23054 gcpro1, gcpro2, etc.
23055 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23057 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second

23062 Rename locals to avoid shadowing.
23064 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

23073 (downcase, upcase1): New static inline functions.
23074 (DOWNCASE, UPCASE1): Reimplement using these functions.
23075 This avoids undefined behavior in expressions like

23109 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

23116 * buffer.c (fix_overlays_before): Mark locals as initialized.
23117 (fix_start_end_in_overlays): Likewise. This function should be
23118 simplified by using pointers-to-pointers, but that's a different

23127 to suppress a gcc -Wclobbered warning that does not seem to be right.
23128 (MAXPATHLEN): Define only if needed.
23130 * process.c (serial_open, serial_configure): Move decls from here ...
23131 * systty.h: ... to here, so that they can be checked.
23133 * fns.c (get_random, seed_random): Move extern decls from here ...

23477 a block, when the outer 'i' will do.

23490 -Wuninitialized does not deduce are never used uninitialized.
23491 (detect_coding_iso_2022): Initialize a local variable that might
23492 be used uninitialized. Leave a FIXME because it's not clear that
