3 * w32fns.c (w32_fullscreen_rect): New function to compute the
4 window rectangle for the given fullscreen mode.
5 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
6 longer tunes the window size. This keeps the window's edges flush
7 with the screen and allows the taskbar to hide itself in fullboth.
9 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
10 window decorations and uses the entire screen.
12 * w32term.h (w32_fullscreen_rect) Add prototype.
13 (struct w32_output): Replace normal_width, normal_height,
14 normal_top, and normal_left members with a single normal_placement
16 (FRAME_NORMAL_WIDTH, FRAME_NORMAL_HEIGHT, FRAME_NORMAL_TOP):
18 (FRAME_NORMAL_PLACEMENT): New macro.
20 2013-04-16 Juanma Barranquero <lekktu@gmail.com>
22 * minibuf.c (Ftest_completion): Silence compiler warning.
24 2013-04-15 Eli Zaretskii <eliz@gnu.org>
26 * w32fns.c (w32_wnd_proc): Add more assertions to investigate

32 * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
33 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
34 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
35 parentheses where appropriate.

39 * keyboard.c (timer_start_idle): Remove no-longer-used local.
41 2013-04-14 Eli Zaretskii <eliz@gnu.org>
43 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
44 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
45 Mention in the doc string that setting these variables takes
46 effect only after a call to set-window-buffer. (Bug#14200)
48 2013-04-13 Eli Zaretskii <eliz@gnu.org>
50 * indent.c (Fvertical_motion): Don't consider display strings on
51 overlay strings as display strings on the buffer position we
52 started from. This prevents vertical cursor motion from jumping
53 more than one line when there's an overlay string with a display
54 property at end of line.
55 Reported by Karl Chen <Karl.Chen@quarl.org> in
56 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

61 already selected (bug#14191).
63 2013-04-11 Eli Zaretskii <eliz@gnu.org>
65 * window.c (Fwindow_end): Test more flags, including the buffer's
66 last_overlay_modified flag, to determine whether the window's
67 display is really up-to-date. Prevents the function from
68 returning a stale value. (Bug#14170)
69 (Fwindow_line_height): Fix the test for up-to-date-ness of the
72 2013-04-10 Eli Zaretskii <eliz@gnu.org>
74 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
75 garbaged only if it is not already the top frame on its TTY.
76 This prevents flickering due to constant redrawing of TTY frames when
77 there are GUI frames open in the same session. (Bug#13864)
79 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
81 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead

113 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
114 This bug was introduced by my 2013-02-25 change that simplified
115 data_start configuration. Without this change, on GNU/Linux
116 an Emacs configured with --enable-profiling fails immediately
117 due to a profiler signal.
118 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
119 with these flags. On platforms where special flags are needed
120 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
121 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
122 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
124 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>

196 Prefer < to > in range checks such as 0 <= i && i < N.
197 This makes it easier to visualize quantities on a number line.
198 This patch doesn't apply to all such range checks,
199 only to the range checks affected by the 2013-03-24 change.
200 This patch reverts most of the 2013-03-24 change.

329 Use contents slot, not buffer, where appropriate.
330 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
331 to avoid deleted windows. Use contents slot instead of buffer.
332 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:
333 * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c:

516 'fullscreen' parameter. Always record previous width and height
517 of the frame, except when switching out of maximized modes, so
518 that they could be restored correctly, instead of resetting to the
519 default frame dimensions. Send SC_RESTORE command to the frame,
520 unless we are going to send SC_MAXIMIZE, to restore the frame
521 resize hints in the mouse pointer shown by the window manager.

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

966 * coding.h (enum coding_result_code): Remove
967 CODING_RESULT_INCONSISTENT_EOL and CODING_RESULT_INSUFFICIENT_MEM.
968 (toplevel): Remove unused CODING_MODE_INHIBIT_INCONSISTENT_EOL.
969 (CODING_MODE_LAST_BLOCK, CODING_MODE_SELECTIVE_DISPLAY)
970 (CODING_MODE_DIRECTION, CODING_MODE_FIXED_DESTINATION)
971 (CODING_MODE_SAFE_ENCODING): Rearrange bit values.
972 (decode_coding_region, encode_coding_region, decode_coding_string):
973 Remove unused compatibility macros.
974 * coding.c (Qinconsistent_eol, Qinsufficient_memory): Remove.
975 (record_conversion_result): Adjust user.
976 (syms_of_coding): Likewise.
977 (ALLOC_CONVERSION_WORK_AREA): Use SAFE_ALLOCA.
978 (decode_coding, encode_coding): Add USE_SAFE_ALLOCA and SAFE_FREE.
979 (decode_coding_object): Simplify since xrealloc never returns NULL.
982 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
984 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
985 * sysdep.c (list_system_processes)
986 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
987 Make it a stub in this case; otherwise the build might fail,
988 and this code hasn't been tested on such hosts anyway.
989 Problem reported by Nelson H. F. Beebe in
990 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
991 and analyzed by Jérémie Courrèges-Anglas in
992 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
994 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
996 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
997 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
998 (get_visually_first_element, move_it_vertically_backward): Ajust users.
999 * bidi.c (bidi_find_paragraph_start): Likewise.
1000 * indent.c (vmotion): Likewise.
1002 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1004 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1005 * filelock.c: Include <c-ctype.h>.
1006 (MAX_LFINFO): New top-level constant.
1007 (lock_info_type): Remove members pid, boot_time. Add members at,
1008 dot, colon. Change user member to be the entire buffer, not a
1009 pointer. This allows us to handle the case where a foreign
1010 pid or boot time exceeds the local range. All uses changed.
1011 (LINKS_MIGHT_NOT_WORK): New constant.
1012 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1013 (defined_WINDOWSNT): Remove.
1014 (MAKE_LOCK_NAME, file_in_lock_file_name):
1015 Always use .#FILE (not .#-FILE) for the file lock,
1016 even if it is a regular file.
1017 (rename_lock_file): New function.
1018 (create_lock_file): Use it.
1019 (create_lock_file, read_lock_data):
1020 Prefer a symbolic link for the lock file, falling back on a
1021 regular file if symlinks don't work. Do not try to create
1022 symlinks on MS-Windows, due to security hassles. Stick with
1023 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1024 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1025 host may be using a Windowsish file system, and cannot use
1026 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1027 doesn't work. Don't fail merely because of a symlink-contents
1028 length limit in the current file system; fall back on regular
1029 files. Increase the symlink contents length limit to 8 KiB, this
1030 should be big enough for any real use and doesn't crunch the
1032 (create_lock_file, lock_file_1, read_lock_data):
1033 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1034 (lock_file_1): Return error number, not bool. All callers changed.
1035 (ELOOP): New macro, if not already defined.
1036 (read_lock_data): Return size of lock file contents, not Lisp object.
1037 All callers changed. Handle a race condition if some other process
1038 replaces a regular-file lock with a symlink lock or vice versa,
1039 while we're trying to read the lock.
1040 (current_lock_owner): Parse contents more carefully, to help avoid
1041 confusing a regular-file lock with some other application's use
1042 of the file. Check for lock file contents being too long, or
1043 not parsing correctly.
1044 (current_lock_owner, lock_file):
1045 Allow foreign pid and boot times that exceed the local range.
1046 (current_lock_owner, lock_if_free, lock_file):
1047 Simplify allocation of lock file contents.
1048 * w32.c (sys_rename_replace): New function, containing most of
1049 the contents of the old sys_rename.
1050 (sys_rename): Use it.
1051 (fchmod): New dummy function.
1052 * w32.h (sys_rename_replace, fchmod): New decls.
1054 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1056 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1057 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1058 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1059 <dmantipov@yandex.ru>.
1061 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1063 * composite.c (get_composition_id, fill_gstring_header):
1064 Use make_uninit_vector where appropriate.
1065 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1066 * xselect.c (clean_local_selection_data): Likewise.
1068 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1070 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1071 * image.c (imagemagick_load_image): Calculate height and width
1072 after flattening the image, not before.
1074 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1076 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1077 * ftfont.c (ftfont_shape_by_flt): Likewise.
1078 * w32uniscribe.c (uniscribe_shape): Likewise.
1080 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1082 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1083 The old approach, which fell back on DIR/.#FILE.0 through
1084 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1085 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1086 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1087 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1088 because the locking mechanism was never reliable in that case).
1089 This patch fixes this and other bugs discovered by a code
1090 inspection that was prompted by
1091 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1092 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1093 to avoid interoperability problems between the MS-Windows and
1094 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1095 instances of Emacs now ignore each others' locks.
1096 * filelock.c (defined_WINDOWSNT): New constant.
1097 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1098 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1099 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1100 regular files on MS-Windows hosts.
1101 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1102 Use SAFE_ALLOCA to avoid problems with long file names.
1103 (MAX_LFINFO): Now a local constant, not a global macro.
1104 (IS_LOCK_FILE): Remove.
1105 (lock_file_1): Don't inspect errno if symlink call succeeds;
1106 that's not portable.
1107 (lock_file): Document that this function can return if lock
1109 (lock_file): Don't access freed storage.
1111 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
1113 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
1115 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1117 * textprop.c: Use bool for booleans.
1118 (validate_interval_range, Fadd_text_properties)
1119 (Fremove_text_properties): Prefer bool to int when either works.
1121 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1123 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1124 If the interval tree changes as a side effect of calling
1125 modify_region, re-do processing starting from the call to
1126 validate_interval_range. (Bug#13743)
1128 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1130 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1133 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1135 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1136 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1137 access to the lock file until it is written and closed.
1140 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1142 * callint.c (Qcall_interactively):
1143 * macros.c (Qexecute_kbd_macro):
1146 2013-02-26 Bastien Guerry <bzg@gnu.org>
1148 * window.c (Frecenter): Tiny docstring enhancement.
1150 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1152 Minor textprop integer cleanup.
1153 * intervals.h, textprop.c (add_text_properties_from_list):
1154 Return void, not int, since nobody uses the return value.
1155 * textprop.c (validate_plist, add_properties, remove_properties)
1156 (Fadd_text_properties):
1157 Don't assume list length fits in int.
1158 (interval_has_all_properties, interval_has_some_properties)
1159 (interval_has_some_properties_list, add_properties, remove_properties)
1160 (Fadd_text_properties, Fremove_text_properties)
1161 (Fremove_list_of_text_properties, text_property_stickiness):
1162 Use bool for booleans.
1163 (Fadd_text_properties, Fremove_text_properties):
1164 (Fremove_list_of_text_properties):
1165 Reindent do-while as per GNU style.

1169 Implement CLASH_DETECTION for MS-Windows.
1171 * filelock.c [WINDOWSNT]: Include w32.h.
1172 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1173 function of that name. Up-case the macro arguments.
1174 (IS_LOCK_FILE): New macro.
1175 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1176 (create_lock_file): New function, with body extracted from
1178 [WINDOWSNT]: Implement lock files by writing a regular file with
1179 the lock information as its contents.
1180 (read_lock_data): New function, on Posix platforms just calls
1182 [WINDOWSNT]: Read the lock info from the file.
1183 (current_lock_owner): Call read_lock_data instead of calling
1184 emacs_readlinkat directly.
1185 (lock_file) [WINDOWSNT]: Run the file name through
1188 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1189 just check if the process by that PID exists.
1191 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1192 also present, as doing so will fail to error out if the file
1195 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1197 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1198 (Fremove_list_of_text_properties): Skip all of the intervals in
1199 the region between START and END that already have resp. don't
1200 have the requested properties, not just the first one.
1201 Add assertions that the loop afterwards always modifies the
1202 properties. (Bug#13743)

1214 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
1215 (START_FILES): Remove. All uses removed.
1216 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.

1232 * vm-limit.c: Move most of mem-limits.h's contents here.
1233 (data_start): New decl. It's OK if this is approximate,
1234 so simplify-away some unnecessary exactness.
1235 (POINTER): Remove; all uses removed.
1236 (data_space_start): Now char *, to avoid casts.
1237 (exceeds_lisp_ptr): New function, replacing the old

1262 Remove, replacing all uses with C89 equivalents. These old
1263 symbols were present only for porting to pre-C89 platforms.

1389 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1390 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1391 was #undeffed earlier, so it cannot be used as a macro here.
1392 Use the constant and not the macro.

1401 MAXDESC, set errno to EMFILE.
1402 (_sys_read_ahead): Update cp->status when failing to read serial
1403 communications input, so that the status doesn't stay at

1411 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1413 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
1416 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
1418 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1420 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
1422 * font.c (font_range): Add pos_byte argument. Adjust comment
1423 and break long line.
1424 * font.h (font_range): Adjust prototype.
1425 * composite.c (autocmp_chars): Pass byte position to font_range.
1426 Break long line. Remove useless prototype and format comment.
1428 2013-02-13 Glenn Morris <rgm@gnu.org>
1430 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1432 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1434 Improve AIX port some more (Bug#13650).
1435 With this, it should be as good as it was in 23.3, though it's
1436 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1437 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1438 * unexaix.c (start_of_text): Remove.
1439 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1440 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1441 (orig_load_scnptr, orig_data_scnptr):
1442 Now off_t, not long, since they are file offsets.
1443 (make_hdr): Use _data, not start_of_data ().
1444 This is the key part of the fix.
1445 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1446 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1448 * pre-crt0.c (data_start): Initialize to 1.
1449 This ports to compilers that optimize the external declaration
1450 'int x = 0;' as if it were 'int x;' to shrink the executable.
1452 Improve AIX port (Bug#13650).
1453 This doesn't fix the bug, but it makes progress: Emacs builds now.
1454 * unexaix.c: Include inttypes.h, stdarg.h.
1455 (report_error, report_error_1): Mark as _Noreturn.
1456 (report_error): Don't report the wrong errno.
1457 (report_error_1): Now varargs. All callers changed.
1458 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1459 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1460 (write_ptr): Use %p to print address rather than %lx and a cast
1461 to unsigned long. Grow buffer a bit, to be safer.
1463 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1465 * bidi.c (bidi_resolve_neutral): After finding the next
1466 non-neutral character, accept NEUTRAL_ON type as well, because
1467 directional control characters, such as LRE and RLE, have their
1468 type converted to that by bidi_resolve_weak. This avoids aborts
1469 when LRE/RLE follows a run of neutrals.
1470 (bidi_move_to_visually_next): Assert that return value of
1471 bidi_peek_at_next_level is non-negative. Negative values will
1474 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1476 Minor getenv-related fixes.
1477 * callproc.c (Fcall_process_region) [!DOS_NT]:
1478 Avoid unnecessary duplicate call to getenv.
1479 * callproc.c (init_callproc):
1480 * dispnew.c (init_display):
1481 * sysdep.c (sys_subshell):
1482 Omit unnecessary cast of getenv or egetenv.
1484 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1486 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1487 Update dependencies.
1489 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1491 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1493 (display_line): Set w->region_showing to the value of
1494 it->region_beg_charpos, not to -1. This fixes redisplay
1495 optimization when cursor is moved up after M->. (Bug#13623)
1497 (try_scrolling): Scroll text up more if point is too close to ZV
1498 and inside the scroll margin. This makes sure point is moved
1499 outside the scroll margin in these cases.
1501 * window.h (struct window): region_showing can no longer be
1504 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1506 Tune by using memchr and memrchr.
1507 * doc.c (Fsnarf_documentation):
1508 * fileio.c (Fsubstitute_in_file_name):
1509 * search.c (find_newline, scan_newline):
1510 * xdisp.c (pos_visible_p, display_count_lines):
1511 Use memchr and memrchr rather than scanning byte-by-byte.
1512 * search.c (find_newline): Rename from scan_buffer.
1513 Omit first arg TARGET, as it's always '\n'. All callers changed.
1515 Clean up read_key_sequence a tiny bit more.
1516 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1517 (read_key_sequence): Remove unused locals.
1519 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1521 Clean up read_key_sequence a bit; reread active keymaps after first event.
1522 * keyboard.c (read_char, read_char_x_menu_prompt)
1523 (read_char_minibuf_menu_prompt):
1524 Replace nmaps+maps with a single `map' arg.
1525 (follow_key): Operate on a single map.
1526 (active_maps): New function.
1527 (test_undefined): Also return true for nil bindings.
1528 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1529 a single (composed) keymap. Remember `first_event' to choose the right
1530 set of active keymaps. Recompute the set of keymaps after receiving
1531 the first event. Remove GOBBLE_FIRST_EVENT.
1532 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1533 * keyboard.h (read_char): Update declaration.
1534 * lread.c (read_filtered_event): Adjust call to read_char.
1536 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1538 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1539 Don't use the limitation on backwards movement when lines are truncated
1540 in the window. (Bug#13675)
1542 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1544 * marker.c (set_marker_internal): If desired position is passed
1545 as a marker, avoid call to buf_charpos_to_bytepos.
1546 * window.c (Fset_window_point): Omit redundant type checking.
1547 (Fset_window_start): Likewise. Format comment.
1548 (window_scroll_pixel_based): Use set_marker_restricted_both
1549 with character and byte positions obtained from an iterator.
1550 (Fset_window_configuration): Use set_marker_restricted_both.
1551 * xdisp.c (message_dolog): Likewise.
1553 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1555 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1556 When text lines are longer than window's screen lines, don't move back
1557 too far. This speeds up some redisplay operations. (Bug#13675)
1559 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1561 * syntax.c (scan_sexps_forward): Fix byte position calculation
1562 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1564 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
1566 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
1567 that was not needed.
1569 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1571 Minor hashing refactoring.
1572 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1573 (sxhash_float): Return EMACS_UINT, for consistency with the other
1575 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1576 non-static inline function and therefore can't use static vars.
1577 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1578 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1579 with the other hash functions.
1581 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1583 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1584 XXXXXX part of the temporary file pattern is not downcased even
1585 when w32-downcase-file-names is non-nil. (Bug#13661)
1587 * xdisp.c (decode_mode_spec): Remove handling of %t.
1589 * msdos.c (careadlinkatcwd): Remove.
1591 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1593 * lread.c (skip_dyn_bytes): New function (bug#12598).
1594 (read1): Use it. Use getc instead of READCHAR to read bytes.
1595 (load_each_byte): Remove. Update users.
1597 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1599 * search.c (scan_buffer): Calculate end byte position just once.

1603 (scan_sexps_forward): Record from_byte and avoid redundant
1604 character to byte position calculation ...
1605 (Fparse_partial_sexp): ... here. Break too long line.
1607 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1609 * lisp.h (make_uninit_vector): New function.
1610 * alloc.c (Fvector, Fmake_byte_code):
1611 * ccl.c (Fregister_ccl_program):
1612 * charset.c (Fdefine_charset_internal, define_charset_internal):

1626 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
1628 * coding.c (Fdefine_coding_system_internal): Use AREF where
1629 argument is known to be a vector.
1630 * fns.c (Flocale_info): Likewise for ASET.
1631 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1632 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1634 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1636 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1639 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
1640 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
1641 updateCollectionBehaviour.
1643 * nsterm.m (NEW_STYLE_FS): Remove.
1644 (ns_last_use_native_fullscreen): New variable.
1645 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
1646 (x_set_window_size): Do not take title bar and tool bar into account
1647 if isFullscreen returns YES.
1648 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1649 (check_native_fs): New function.
1650 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
1651 (ns_term_init): Remove NEW_STYLE_FS.
1652 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
1653 and tool bar if isFullscreen returns NO.
1654 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
1655 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
1656 with HAVE_NATIVE_FS.
1657 (window:willUseFullScreenPresentationOptions:): New method.
1658 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
1659 Hide toolbar if not enabled (Bug#13444).
1660 (windowDidExitFullScreen:): Call updateCollectionBehaviour.

1662 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
1663 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
1664 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
1665 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
1666 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1667 (syms_of_nsterm): Add ns-use-native-fullscreen.
1669 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1671 * fileio.c (Qchoose_write_coding_system): Now static.
1673 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1675 * xdisp.c (window_buffer_changed): region_showing can be negative,
1676 which still means region is being displayed.
1677 (redisplay_internal): Resurrect code that forced redisplay of the
1678 whole window when showing region and the mark has changed.
1679 Record the new mark position to allow redisplay optimizations.
1680 (display_line): If it->region_beg_charpos is non-zero, set the
1681 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1683 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1684 not bitfield of 1 bit.
1686 2013-02-03 Daniel Colascione <dancol@dancol.org>
1688 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1689 daemon mode works on cygw32 when Emacs is installed and not just
1692 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1694 Avoid file time stamp bug on MS-Windows (Bug#13149).
1695 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1696 as FAT32 doesn't update time stamps when truncating them.
1697 Also, check that a file time stamp is not a multiple of 100 ns;
1698 this should catch all instances of the problem on MS-Windows,
1699 as its native file system resolution is 100 ns or worse, and
1700 checking for a non-multiple of 100 ns should impose only a small
1701 overhead on systems with ns resolution.
1703 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1705 Avoid encoding file names on MS-Windows when they need to be run
1706 through dostounix_filename.
1707 * w32.c (normalize_filename): Accept an additional argument
1708 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1709 downcase it even if w32-downcase-file-names is non-nil.
1710 (dostounix_filename): Accept an additional argument MULTIBYTE and
1711 pass it to normalize_filename.
1712 (emacs_root_dir): Adjust.
1714 * msdos.h (dostounix_filename): Adjust prototype.
1716 * w32.h (dostounix_filename): Adjust prototype.
1718 * msdos.c (dostounix_filename): Accept an additional argument and
1720 (init_environment): Adjust callers of dostounix_filename.
1722 * fileio.c (Ffile_name_directory, file_name_as_directory)
1723 (directory_file_name, Fexpand_file_name)
1724 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1726 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1728 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1729 variables, as egetenv is case-insensitive for DOS_NT.
1731 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1732 with an encoded file name.
1734 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1735 Adjust calls to dostounix_filename.
1737 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1739 * unexw32.c (unexec): Adjust call to dostounix_filename.
1741 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1743 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1746 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1749 * callproc.c (Fcall_process): Make sure program name in PATH and
1750 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1751 is passed to exec/spawnve, which fails unless the file-name
1754 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1755 even if w32-quote-process-args is nil.
1757 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1759 Fix timestamp bug when write-region appends nothing (Bug#13149).
1760 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1761 the file's time stamp doesn't change if Emacs happens to write nothing
1762 to the file, and on a buggy file system this could cause Emacs to
1763 incorrectly infer that the file system doesn't have the bug.
1764 Avoid this problem by inhibiting the inference in this case.
1766 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1768 * window.h (struct window): Convert base_line_number, base_line_pos
1769 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1770 Convert region_showing member from Lisp_Object to bitfield.
1771 Remove sequence_number member. Adjust comments.
1772 * window.c (sequence_number): Remove.
1773 (make_window): Initialize column_number_displayed.
1774 * print.c (print_object): Follow the printed representation of
1775 frames and print window pointer to distinguish between windows.
1776 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1777 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1778 (wset_column_number_displayed, wset_region_showing): Remove.
1779 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1780 (try_scrolling, try_cursor_movement, redisplay_window)
1781 (try_window_reusing_current_matrix, try_window_id, display_line)
1782 (display_mode_lines, decode_mode_spec): Adjust users.
1783 * .gdbinit (pwinx): Do not print sequence_number.
1785 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1787 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1788 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1789 * dired.c: Include <fcntl.h>.
1790 (open_directory): New function, which uses open and fdopendir
1791 rather than opendir. DOS_NT platforms still use opendir, though.
1792 (directory_files_internal, file_name_completion): Use it.
1793 (file_attributes): New function, with most of the old Ffile_attributes.
1794 (directory_files_internal, Ffile_attributes): Use it.
1795 (file_attributes, file_name_completion_stat): First arg is now fd,
1796 not dir name. All uses changed. Use fstatat rather than lstat +
1798 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1799 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1800 (emacs_readlinkat): New function, with much of the old
1801 Ffile_symlink_p, but with an fd argument for speed.
1802 It uses readlinkat rather than careadlinkatcwd, so that it
1803 need not assume the working directory.
1804 (Ffile_symlink_p): Use it.
1805 * filelock.c (current_lock_owner): Use emacs_readlinkat
1806 rather than emacs_readlink.
1807 * lisp.h (emacs_readlinkat): New decl.
1808 (READLINK_BUFSIZE, emacs_readlink): Remove.
1809 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1810 (emacs_norealloc_allocator, emacs_readlink): Remove.
1811 This stuff is moved to fileio.c.
1812 * w32.c (fstatat, readlinkat): New functions.
1813 (careadlinkat): Don't check that fd == AT_FDCWD.
1814 (careadlinkatcwd): Remove; no longer needed.
1816 2013-01-31 Glenn Morris <rgm@gnu.org>
1818 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
1819 (Fwrite_region): Update for new choose_write_coding_system args.
1820 Move the last piece of choose_write_coding_system here. (Bug#13522)
1821 (syms_of_fileio): Add choose-write-coding-system.
1823 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1825 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1826 (sys_close): Zero out the flags for the file descriptor before
1827 closing it. (Bug#13546)
1829 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1830 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1831 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1834 * w32.c (w32_get_long_filename, init_environment, readlink):
1835 Support file names encoded in DBCS codepages.
1836 (readlink): Use the current file-name-coding-system, not the ANSI
1837 codepage, to decode and handle targets of symlinks.
1839 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1841 * w32.c (opendir): Now accepts a 'const char *'.
1843 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1845 Remove obsolete redisplay code. See the discussion at
1846 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1847 * dispnew.c (preemption_period, preemption_next_check): Remove.
1848 (Vredisplay_preemption_period): Likewise.
1849 (update_frame, update_single_window, update_window, update_frame_1):
1850 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1851 used, following the 2012-06-22 change.
1853 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1855 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1857 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1859 * font.c (num_fonts): Remove the leftover from old
1860 debugging code. Adjust comment style here and there.
1861 * insdel.c (insert_1): Remove.
1862 * lisp.h (insert_1): Remove prototype.

1865 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1867 * w32.c (max_filename_mbslen): New function.
1868 (normalize_filename, readdir): Use it to detect locales where ANSI
1869 encoding of file names uses a double-byte character set (DBCS).
1870 If a DBCS encoding is used, advance by characters using
1871 CharNextExA, instead of incrementing a 'char *' pointer.
1872 Use _mbslwr instead of _strlwr. (Bug#13515)
1874 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1875 request of memory reservation to 1.7GB. (Bug#13065)
1877 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1879 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1880 at check_extra_latin label. (Bug#13505)
1882 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1884 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1885 Avoid redundant calls to strlen.
1887 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1889 Drop async_visible and async_iconified fields of struct frame.
1890 This is possible because async input is gone; for details, see
1891 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1892 * frame.h (struct frame): Remove async_visible and async_iconified
1893 members, convert garbaged to unsigned bitfield. Adjust comments.
1894 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1895 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1896 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1897 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1898 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1900 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1901 properly. Likewise for obscured.
1903 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1906 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1908 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1910 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1911 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1913 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1915 * xdisp.c (message2, message2_nolog): Remove functions.
1916 (message3, message3_nolog): Extract nbytes and multibyteness directly
1917 from the string. Change all callers.
1918 (message3_nolog): Don't set message_enable_multibyte since set_message
1919 will reset it anyway.
1920 (message1, message1_nolog): Use message3.
1921 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1922 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1923 (set_message): Drop all but the second arg, which has to be a string.
1924 (set_message_1): Simplify now that we know that a1 is NULL and the
1925 second arg is a string.
1926 * frame.h (struct frame): Remove `message_buf' field.
1927 Use glyphs_initialized_p instead.
1928 (FRAME_MESSAGE_BUF): Remove macro.
1929 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1930 * lisp.h (message2, message2_nolog): Remove declarations.
1931 (message3, message3_nolog): Update declarations.
1932 * keyboard.c (read_char_minibuf_menu_text)
1933 (read_char_minibuf_menu_width): Remove vars.
1934 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1935 to correctly handle multibyte strings.
1936 * frame.c (delete_frame): Don't free message_buf any more.
1937 * editfns.c (message_text, message_length): Remove vars.
1938 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1939 * fileio.c (auto_save_error): Use message3 instead of message2.
1940 * dispnew.c (adjust_frame_message_buffer): Remove function.
1942 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1944 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1945 real estate used for the tool bar and the menu bar.
1947 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1949 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1950 hidden buffer is prepared to modification (Bug#13164).
1952 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1954 * window.h (struct window): Change window_end_valid member from
1955 Lisp_Object to a bitfield. Adjust comments.
1956 (wset_window_end_valid): Remove.
1957 * window.c (adjust_window_count): Clear window_end_valid.
1958 (Fwindow_end): Adjust user. Remove ancient #if 0 code.

1960 (Fsplit_window_internal, Fdelete_other_windows_internal)
1961 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1962 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1963 * xdisp.c (check_window_end, reconsider_clip_changes)
1964 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1965 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1966 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1968 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1970 * xdisp.c (mark_window_display_accurate): Simplify the loop
1971 assuming that the only one of vchild, hchild or buffer window
1972 slots is non-nil. Call mark_window_display_accurate_1 for
1973 the leaf windows only.
1974 (mark_window_display_accurate_1): Always assume leaf window.
1977 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1979 * emacs.c (Qkill_emacs_hook): Now static.
1981 * fileio.c (Finsert_file_contents): Simplify.
1982 Remove unnecessary assignments and tests.
1984 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1986 * w32.c (acl_set_file): Don't test for errors unless
1987 set_file_security returns FALSE. Avoids spurious errors when
1990 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1992 * fileio.c (Finsert_file_contents): Revert code introduced at
1993 2013-01-18 in favor of the simpler and generally better fix.
1994 Save stack space by removing 'buffer' and reusing 'read_buf'
1997 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1999 * lisp.h (eabs): Define unconditionally (Bug#13419).
2000 The old "#if !defined (eabs)" was an unnecessary revenant of back
2001 when this macro was called "abs". Document 'eabs' better.
2003 2013-01-19 Glenn Morris <rgm@gnu.org>
2005 * fns.c (Frandom): Doc fix.
2007 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2009 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2010 segfault when there are lots of overlays.
2012 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2013 when there are lots of overlays.
2014 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2015 for the details and a way to reproduce.
2017 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2019 * fileio.c: Use O_APPEND to append.
2020 This corresponds better to the natural interpretation of "append",
2021 and avoids the need to open the output file twice, or to invoke
2022 lseek when APPEND is neither nil nor a number.
2023 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2024 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2025 file possibly twice, and lseeking to its end; this avoids the
2026 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2027 at the same time: the combination is never needed and apparently
2028 it doesn't work with DOS_NT.
2030 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2031 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2033 Allow floating-point file offsets.
2034 Problem reported by Vitalie Spinu in
2035 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2036 * fileio.c (emacs_lseek): Remove.
2037 (file_offset): New function.
2038 (Finsert_file_contents, Fwrite_region): Use it.
2040 2013-01-19 Chong Yidong <cyd@gnu.org>
2042 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2043 aborting on Fsignal (Bug#13289).
2045 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2047 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2048 set_file_security as failure due to insufficient privileges.
2049 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2050 (fstat): Return owner and group like 'stat' and 'lstat' do.
2052 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2054 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2055 The bug was observed on Ubuntu operating inside a virtual machine,
2056 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2057 The workaround introduces a race condition on non-buggy hosts,
2058 but it's an unlikely race and anyway there's a nearly identical
2059 nearby race that can't be fixed.
2060 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2062 (Fwrite_region): Test for file system time stamp bug.
2063 (init_fileio): New function.
2064 * lisp.h (init_fileio): Declare it.
2065 * emacs.c (main): Call it.
2067 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2068 and make it more consistent with other stat-failure diagnostics.
2070 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2072 Fix crash when inserting data from non-regular files.
2073 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2074 for the error description produced by valgrind.
2075 * fileio.c (read_non_regular): Rename to read_contents.
2076 Free Lisp_Save_Value object used to pass parameters.
2077 (read_non_regular_quit): Rename to read_contents_quit.
2078 (Finsert_file_contents): Redesign internal file reading loop to adjust
2079 gap and end positions after each read and so help make_gap to work
2080 properly. Do not signal an I/O error too early and so do not leave
2081 not yet decoded characters in a buffer, which was the reason of
2082 redisplay crash. Use list2 to build return value. Adjust comments.
2084 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2086 Close a race when statting and reading files (Bug#13149).
2087 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2088 This avoids a race if the file is renamed between stat and open.
2089 This race is not the problem originally noted in Bug#13149;
2090 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2092 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
2094 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
2095 objects, related functions and macros.
2096 (make_save_value): Adjust prototype.
2097 (make_save_pointer): New prototype.
2098 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
2099 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2100 * alloc.c (format_save_value): Rename to make_save_value.
2101 (make_save_pointer): New function.
2102 (record_xmalloc): Use make_save_pointer.
2103 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2104 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2105 Change users of make_save_value to make_save_pointer.
2106 Likewise for format_save_value and make_save_value.
2108 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

2115 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
2117 * alloc.c (free_save_value): Now static.
2119 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2121 * keymap.c (map_keymap_internal): Use format_save_value.
2122 (map_keymap_char_table_item): Adjust accordingly.
2123 * fileio.c (non_regular_fd, non_regular_inserted)
2124 (non_regular_nbytes): Remove.
2125 (Finsert_file_contents): Convert trytry to ptrdiff_t.
2126 Use format_save_value to pass parameters to read_non_regular.
2127 (read_non_regular): Use XSAVE_ macros to extract parameters.
2129 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
2131 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
2133 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2135 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2136 extraction from any Lisp_Save_Value slot. Add type checking.
2137 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
2138 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
2139 * xselect.c: All users changed.
2141 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

2146 (format_save_value): New prototype.
2147 * alloc.c (allocate_misc): Revert back to static.
2148 (format_save_value): New function to build Lisp_Save_Value
2149 object with the specified internal structure.
2150 (make_save_value): Reimplement using format_save_value.
2151 * editfns.c (save_excursion_save): Use format_save_value.
2152 (save_excursion_restore): Use XSAVE_OBJECT.
2154 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
2156 Avoid needless casts with XSAVE_POINTER.
2157 * alloc.c (mark_object) [GC_MARK_STACK]:
2158 * dired.c (directory_files_internal_unwind):
2159 * fileio.c (do_auto_save_unwind):
2160 * gtkutil.c (pop_down_dialog):
2161 * keymap.c (map_keymap_char_table_item):
2162 * lread.c (load_unwind):
2163 * nsmenu.m (pop_down_menu):
2164 * print.c (print_object) [GC_MARK_STACK]:
2165 * xfns.c (clean_up_file_dialog):
2166 * xmenu.c (cleanup_widget_value_tree):
2167 Omit casts between XSAVE_POINTER and a pointer type.
2169 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2171 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
2172 * eval.c (eval_sub): Protect `form' from being GCed before its
2173 car and cdr becomes protected with the backtrace entry.
2175 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2177 Make Lisp_Save_Value more versatile storage for up to four objects.
2178 * lisp.h (toplevel): Enumeration to describe types of saved objects.
2179 (struct Lisp_Save_Value): New layout. Adjust comments.
2180 (XSAVE_POINTER): New macro.
2181 (XSAVE_INTEGER): Likewise.
2182 (allocate_misc): Add prototype.
2183 (free_misc): Likewise.
2184 * alloc.c (allocate_misc): Now global.
2185 (free_misc): Likewise. Adjust comment.
2186 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
2187 (free_save_value): Likewise.
2188 (mark_object): Likewise.
2189 * editfns.c (save_excursion_save): Pack everything within
2190 Lisp_Save_Value and so avoid xmalloc.
2191 (save_excursion_restore): Adjust to match new layout. Use free_misc
2192 because we do not allocate extra memory any more. Add eassert.
2193 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2194 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
2195 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
2196 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

2202 (nsfont_draw): Remove disabling of LCD smoothing.
2203 (ns_glyph_metrics): Add LCD_SMOOTHING_MARGIN to bearings to fix
2204 Bug#11484 with LCD smoothing on.
2206 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
2208 Fix SIGDANGER handlers, for AIX (Bug#13408).
2209 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
2210 Move handlers here from emacs.c; they were out of place.
2212 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
2214 * xterm.c (syms_of_xterm): Adjust documentation for
2215 scroll-bar-adjust-thumb-portion.
2217 2012-12-31 Adam Sjøgren <asjo@koldfront.dk> (tiny change)

2220 determine whether scroll bar thumb size should be adjusted or
2221 not. Use variable for MOTIF.
2223 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for
2226 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

2230 (doCommandBySelector:): Set processingCompose to NO.
2232 * nsfont.m (ns_findfonts): Add block/unblock_input calls.
2233 Remove check for fkeys count > zero, block/unblock fixes the real bug.
2234 (nsfont_list_family): Add block/unblock_input calls.
2235 (nsfont_open): Move block_input earlier. Add unblock_input before early
2237 (nsfont_draw): Add block/unblock_input calls.
2239 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
2241 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
2242 for old_charpos and old_bytepos.
2244 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>
2246 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
2247 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
2248 Clear tzvalbuf_in_environ if this workaround is in effect.
2249 Problem and fix reported by Kazuhiro Ito.
2251 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>
2253 * insdel.c (Fcombine_after_change_execute, syms_of_insdel):
2254 Fix ambiguous doc string cross-reference(s).
2256 * keyboard.c (Fcommand_execute, syms_of_keyboard): Fix ambiguous
2257 doc string cross-reference(s).
2259 * window.c (Fwindow_point, syms_of_window): Fix ambiguous doc
2260 string cross-reference(s).
2262 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
2264 Avoid unnecessary byte position calculation for the gap movement.
2265 Since all users of move_gap do CHAR_TO_BYTE for other purposes
2266 anyway, all of them should use move_gap_both instead.
2267 * lisp.h (move_gap): Remove prototype.
2268 * insdel.c (move_gap): Remove.
2269 (move_gap_both): Add eassert.
2270 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.
2271 * xml.c (parse_region): Likewise.
2273 2013-01-11 Paul Eggert <eggert@cs.ucla.edu>
2275 emacsclient -t should not suspend Emacs server (Bug#13387)
2276 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
2278 * term.c (init_tty): Use them instead of rolling our own code.
2279 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
2280 switches from 'signal' to 'pthread_sigmask', which is safer in
2281 multithreaded applications.
2282 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
2283 which has already arranged for that.
2284 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
2285 This is the main part of the bug fix.
2287 2013-01-10 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)
2289 * gtkutil.c (xg_initialize): Add ifdef HAVE_FREETYPE around
2290 x_last_font_name (Bug#13403).
2292 2013-01-10 Dmitry Antipov <dmantipov@yandex.ru>
2294 Omit buffer_slot_type_mismatch and use generic predicates to enforce
2295 the type of per-buffer values where appropriate.
2296 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
2297 predicate, which is how it's really used now. Adjust comment.
2298 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
2299 * buffer.c (buffer_slot_type_mismatch): Remove.
2300 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
2301 predicate. Adjust comment.
2302 (syms_of_buffer): Use Qsymbolp for major-mode. Use Qintegerp for

2304 left-margin-width, right-margin-width, left-fringe-width,
2305 right-fringe-width, scroll-bar-width and buffer-display-count.
2306 Use Qstringp for default-directory, buffer-file-name,

2361 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2362 Display the newline glyph more unambiguously.
2364 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2366 * nsterm.m (ns_draw_underwave):
2367 * w32term.c (w32_draw_underwave):
2368 * xterm.c (x_draw_underwave): Make underwave look more triangular
2369 and also degrade gracefully for small fonts. (Bug#13000)
2371 * nsterm.m (ns_draw_text_decoration):
2372 * w32term.c (x_draw_glyph_string):
2373 * xterm.c (x_draw_glyph_string): Don't use previous underline
2374 thickness and position if previous underline type is underwave.
2376 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>

2394 * term.c (tty_ins_del_lines):
2395 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2396 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2398 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2400 * w32.c (unsetenv): Set up the string passed to _putenv

2407 * coding.c (Qmac): Now static.
2409 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2411 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.

2429 (xg_update_submenu): Skip tearoff only if
2430 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2431 (xg_initialize): Initialize xg_detached_menus only if
2432 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2434 * xterm.h (struct x_output): Surround handlebox_widget with
2435 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,

2461 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2463 Port EXTERNALLY_VISIBLE to Clang 3.2.
2464 * conf_post.h (__has_attribute): New macro.
2465 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2467 2012-12-27 Glenn Morris <rgm@gnu.org>
2469 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2470 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2472 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2474 * fileio.c (file_name_as_directory, directory_file_name):
2475 Accept an additional argument MULTIBYTE to indicate whether the input C
2476 came from a multibyte or a unibyte Lisp string; all callers
2477 adjusted. Don't assume the input string is always multibyte.
2479 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2480 don't ENCODE_FILE them, and return a unibyte string if the input
2482 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2483 don't assume the input strings will always be multibyte. If the
2484 input strings are multibyte, decode strings obtained from C
2487 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2489 * lisp.h (toplevel): Add two notices to the comment about
2490 defining a new Lisp data type.

2498 * keyboard.c (record_asynch_buffer_change): Initialize an event
2499 only if it's really needed.
2500 * frame.h (enum output_method): Remove output_mac member since
2501 it's a leftover from the deleted code.
2502 * frame.c (Fframep): Adjust user here ...
2503 * terminal.c (Fterminal_live_p): ... and here.
2504 * coding.c (Qmac): Now here because it's only used to denote
2505 end-of-line encoding type.
2506 (syms_of_coding): DEFSYM it.
2507 * frame.h (Qmac): Remove duplicated declaration.
2509 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2511 * window.c (select_window_1): Now static, since it's used only here.
2513 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2515 * window.c (window_body_cols): Subtract display margins from the
2516 window body width on TTYs as well. See
2517 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2518 for the original report.
2520 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2522 * xdisp.c (redisplay_window): Remove inner local variable
2523 because the outer shadowed one has the same meaning.
2524 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2526 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2527 (xg_create_tool_bar): Adjust users.
2529 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2531 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2532 * buffer.c (Fget_buffer_create): Use it to set compact field of
2533 struct buffer_text to avoid accessing an uninitialized value
2534 when compact_buffer is called for the first time.
2535 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2536 (Fset_buffer_modified_p): Use buffer_window_count to check
2537 whether the buffer is displayed in some window.
2538 * xdisp.c (message_dolog): Likewise.
2540 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2542 * w32.c (acl_set_file): If setting the file security descriptor
2543 fails, and the new DACL is identical to the existing one, silently
2544 return success. This fixes problems for users backing up their
2545 own files without having the necessary privileges for setting
2546 security descriptors.
2548 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2550 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2551 after WaitForSingleObject returns normally. This expedites reader
2552 thread shutdown when delete_child triggers it.
2553 (reap_subprocess): More accurate commentary for why we call
2554 delete_child only when cp->fd is negative.
2556 * w32.c (sys_close): Do not call delete_child on a subprocess
2557 whose handle is not yet closed. Instead, set its file descriptor
2558 to a negative value, so that reap_subprocess will call
2559 delete_child on that subprocess when its SIGCHLD arrives.
2560 This avoids closing handles used for communications between sys_select
2561 and reader_thread, which doesn't give sys_select a chance to
2562 notice that the process exited and invoke the SIGCHLD handler for
2565 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2567 * nsfns.m (Fns_do_applescript): Run event loop until script has
2568 been executed (Bug#12969).

2576 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2578 * w32term.c (w32fullscreen_hook): New function.
2579 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2581 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2583 * fileio.c (Finsert_file_contents): Doc fix.
2585 * w32proc.c (new_child, delete_child, find_child_pid): For a
2586 subprocess, consider its slot being in use as long as its process
2587 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2588 slot when a new process is started immediately after killing
2589 another one, without waiting enough time for the first process to
2590 be reaped and resources allocated for it be orderly freed.
2592 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2594 2012-12-21 Chong Yidong <cyd@gnu.org>
2596 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2598 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2600 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2602 * w32.c (get_name_and_id): Always pass NULL as the first argument
2603 of lookup_account_sid. Avoids crashes with UNC file names that
2604 refer to DFS domains, not to specific machine names. (Bug#12621)
2605 Remove now unused argument FNAME; all callers changed.
2606 (get_file_owner_and_group): Remove now unused argument FNAME; all
2609 2012-12-21 Chong Yidong <cyd@gnu.org>
2611 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2612 error for invalid chars, don't check for a nil return value.
2614 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2616 Avoid calls to CHAR_TO_BYTE if byte position is known.
2617 * editfns.c (make_buffer_string_both): Use move_gap_both.
2618 (Fbuffer_string): Use make_buffer_string_both.

2622 (charpos_to_bytepos): Remove.
2623 * fileio.c (Finsert_file_contents): Use move_gap_both.
2624 * search.c (Freplace_match): Likewise.
2625 * process.c (process_send_region): Likewise. Use convenient
2626 names for byte positions.
2627 * lisp.h (charpos_to_bytepos): Remove prototype.
2628 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2629 * insdel.c (move_gap): Likewise.

2637 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2638 (redisplay_internal): Don't bother selecting the frame to get the
2639 proper value of frame-local variables (bug#13225).
2641 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2643 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2644 Rename 4th argument since it may be buffer or string. Adjust comment.
2645 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2647 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2649 * coding.c (Fdetect_coding_region): Do not check start and end with
2650 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2651 (code_convert_region): Likewise.
2653 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2655 * w32.c (acl_get_file, acl_set_file): Run the file name through
2656 map_w32_filename, and resolve any symlinks in the file name, like
2658 (acl_set_file): Call revert_to_self, if any privileges were

2664 ($(BLD)/w32.$(O)): Update dependencies.
2666 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2668 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2669 propagate redisplay's scrolling (if any) to the right window.
2670 (redisplay_internal): Use ensure_selected_frame.
2671 (display_mode_lines): Complete last fix.
2672 * window.c (select_window_1): New func, extracted from select_window.
2673 (select_window): Use it.

2700 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2702 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2703 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2704 for some of that bug's symptoms can now cause Emacs to abort.
2705 Remove the workaround.
2706 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2707 The bug that caused SIGCHLD to get lost has been fixed, and the
2708 workaround for it can now cause Emacs to abort.
2710 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2712 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2713 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2714 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

2786 'lstat', which don't need that information, much faster.
2788 * dired.c (Ffile_attributes) [WINDOWSNT]:
2789 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2790 owner and group information from 'lstat'.
2792 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2794 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2795 as that confuses set-auto-coding, so insist on the head-read
2796 returning the full 1024 bytes. Let lseek compute the tail offset;
2797 less work for us. Do not ignore I/O errors when reading the tail.
2799 * xdisp.c: Minor style fixes.
2800 (init_iterator): Hoist assignment out of if-expression.
2801 (markpos_of_region): Callers now test for sign, not for -1.

2827 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2828 Remove unnecessary S_ISLNK test, as (contra the comments) this
2829 function can't copy symlinks. Improve quality of error message
2830 when attempting to copy files that are neither regular files nor

2861 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2862 left_box_line_p and right_box_line_p flags of the glyph for R2L
2863 glyph rows. (Bug#13011)

2877 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
2878 encoded_file_name, which is what it is.
2880 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2882 Consistently use marker_position and marker_byte_position.

2904 Windows file notification functionality unless WINDOWSNT.
2906 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
2909 * w32fns.c (cache_system_info): Initialize the global hinst
2910 variable here so various initialization calls DTRT.
2912 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
2913 (hinst): Remove unneeded extern declaration.
2914 (_start): Remove initialization of above variables; remove
2915 initialization of hinst, as cache_system_info now does that.

3059 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3061 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).

3063 * dbusbind.c (Fdbus_init_bus):
3065 * xterm.c (x_term_init):

3076 no longer needed here.
3077 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
3078 Move to inside set_time_zone_rule; they don't need file scope any more.
3079 (set_time_zone_rule): Maintain the TZ=value string separately.
3080 (syms_of_editfns): Don't initialize initial_tz;
3081 init_editfns now does it.
3082 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.

3102 Remove USG and vlimit methods; no longer used these days.
3103 Add #error catchall just in case.
3105 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3106 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,

3129 This will cause a production Emacs to dump core instead of
3132 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3134 * frame.c (make_frame): Do not set window's buffer to t.
3135 * window.c (Fsplit_window_internal): Likewise. Previously it was
3136 used to indicate that the window is being set up. Now we use
3137 set_window_buffer for all new windows, so the condition in ...
3138 (Fset_window_buffer): ... is always true and can be removed.
3140 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3142 Convenient macro to check whether the buffer is hidden.
3143 * buffer.h (BUFFER_HIDDEN_P): New macro.

3169 Fix a recently-introduced delete-process race condition.
3170 * callproc.c, process.h (record_kill_process):
3171 New function, containing part of the old call_process_kill.
3172 (call_process_kill): Use it.
3173 This does not change call_process_kill's behavior.
3174 * process.c (Fdelete_process): Use record_kill_process to fix a
3175 race condition that could cause Emacs to lose track of a child.
3177 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3179 Avoid code duplication between prev_frame and next_frame.
3180 * frame.c (candidate_frame): New function. Add comment.
3181 (prev_frame, next_frame): Use it. Adjust comment.
3183 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3185 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3186 fails, signal an error instead of continuing with an empty
3188 Encode expanded temp file pattern before passing it to mkstemp or
3191 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3192 Encode the file name before passing it to dostounix_filename, in
3193 case it will downcase it (under w32-downcase-file-names).
3196 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3198 Minor call-process cleanups.
3199 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3200 at the same time as other platforms, to simplify analysis.
3201 No need for fd0_volatile since we have synch_process_fd.
3202 Avoid needless emacs_close; arg is always negative.
3204 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3206 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3209 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3211 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3212 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
3213 and mouse_face_hidden members to a bitfields.

3218 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3219 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3220 members to a bitfields.
3222 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3224 Don't let call-process be a zombie factory (Bug#12980).
3225 Fixing this bug required some cleanup of the signal-handling code.
3226 As a side effect, this change also fixes a longstanding rare race
3227 condition whereby Emacs could mistakenly kill unrelated processes,
3228 and it fixes a bug where a second C-g does not kill a recalcitrant
3229 synchronous process in GNU/Linux and similar platforms.
3230 The patch should also fix the last vestiges of Bug#9488,
3231 a bug which has mostly been fixed on the trunk by other changes.
3232 * callproc.c, process.h (synch_process_alive, synch_process_death)
3233 (synch_process_termsig, sync_process_retcode):
3234 Remove. All uses removed, to simplify analysis and so that
3235 less consing is done inside critical sections.
3236 * callproc.c (call_process_exited): Remove. All uses replaced
3237 with !synch_process_pid.
3238 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3239 These take the role of what used to be in unwind-protect arg.
3241 (block_child_signal, unblock_child_signal):
3242 New functions, to avoid races that could kill innocent-victim processes.
3243 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3244 (call_process_kill): Record killed processes as deleted, so that
3245 zombies do not clutter up the system. Do this inside a critical
3246 section, to avoid a race that would allow the clutter.
3247 (call_process_cleanup): Fix code so that the second C-g works again
3248 on common platforms such as GNU/Linux.
3249 (Fcall_process): Create the child process in a critical section,
3250 to fix a race condition. If creating an asynchronous process,
3251 record it as deleted so that zombies do not clutter up the system.
3252 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3253 light of these changes. Omit unnecessary call to emacs_close
3254 before failure, as the unwind-protect code does that.
3255 * callproc.c (call_process_cleanup):
3256 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3257 * process.c (record_deleted_pid): New function, containing
3258 code refactored out of Fdelete_process.
3259 (Fdelete_process): Use it.
3260 (process_status_retrieved): Remove. All callers changed to use
3261 child_status_change.
3262 (record_child_status_change): Remove, folding its contents into ...
3263 (handle_child_signal): ... this signal handler. Now, this
3264 function is purely a handler for SIGCHLD, and is not called after
3265 a synchronous waitpid returns; the synchronous code is moved to
3266 wait_for_termination. There is no need to worry about reaping
3267 more than one child now.
3268 * sysdep.c (get_child_status, child_status_changed): New functions.
3269 (wait_for_termination): Now takes int * status and bool
3270 interruptible arguments, too. Do not record child status change;
3271 that's now the caller's responsibility. All callers changed.
3272 Reimplement in terms of get_child_status.
3273 (wait_for_termination_1, interruptible_wait_for_termination):
3274 Remove. All callers changed to use wait_for_termination.
3275 * syswait.h: Include <stdbool.h>, for bool.
3276 (record_child_status_change, interruptible_wait_for_termination):
3278 (record_deleted_pid, child_status_changed): New decls.
3279 (wait_for_termination): Adjust to API changes noted above.
3281 * bytecode.c, lisp.h (Qbytecode): Remove.
3282 No longer needed after 2012-11-20 interactive-p changes.
3284 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3286 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3287 the scroll margin, move point outside the margin. (Bug#13055)

3296 * lisp.h (modify_region): Rename to...
3297 (modify_region_1): ...new prototype.
3298 * textprop.c (modify_region): Now static. Adjust users.
3299 * insdel.c (modify_region): Rename to...
3300 (modify_region_1): ...new function to work with current buffer.
3301 Adjust comment and users. Use true and false for booleans.
3303 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3305 * alloc.c (free_save_value): New function.
3306 (safe_alloca_unwind): Use it.

3308 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3310 (save_excursion_restore): Adjust to match saved data structure.
3311 Use free_save_value to offload some work from GC. Drop obsolete
3314 2012-12-03 Chong Yidong <cyd@gnu.org>
3316 * fileio.c (Vauto_save_list_file_name): Doc fix.
3318 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3320 * w32fns.c: Remove prototype of atof.
3321 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3323 (file_dialog_callback): Make it UINT_PTR.
3325 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3328 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3329 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3332 2012-12-03 Glenn Morris <rgm@gnu.org>
3334 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3336 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3338 Fix xpalloc confusion after memory is exhausted.
3339 * alloc.c (xpalloc): Comment fix.
3340 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3341 and signals an error, do not clear charset_table_size, as
3342 charset_table is still valid.
3343 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3345 Use execve to avoid need to munge environ (Bug#13054).
3346 * callproc.c (Fcall_process):
3347 * process.c (create_process):
3348 Don't save and restore environ; no longer needed.
3349 * callproc.c (child_setup):
3350 Use execve, not execvp, to preserve environ.
3352 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3354 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3356 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3358 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3359 display for sliced images (Bug#10500).
3361 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3363 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3365 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3366 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3368 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3370 * xdisp.c (window_outdated): Remove eassert since it hits
3371 some suspicious corner cases (see Bug#13007 and Bug#13012).
3372 (mode_line_update_needed): New function.

3377 (buffer_shared_and_changed): ...near to its real use.
3379 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3381 * callproc.c (Fcall_process): Don't misreport vfork failure.
3383 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3385 * callproc.c (Fcall_process): Fix vfork portability problems.
3386 Do not assume that fd[0], count, filefd, and save_environ survive
3387 vfork. Fix bug whereby wrong errno value could be reported for
3388 pipe failure. Some minor cleanups, too, as follows. Move buf and
3389 bufsize to the context where they're needed. Change new_argv to
3390 be of type char **, as this is more convenient and avoids casts.
3391 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3392 Now local constants, not macros.
3394 2012-11-18 Kenichi Handa <handa@gnu.org>
3396 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3397 for the variable "f".

3427 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
3428 highlighting on the frame was cleared. Prevents assertion
3429 violations when repeatedly clicking on the "Top" link of the
3430 "bread-crumbs" in Info buffers.
3432 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>

3440 were always defined.
3442 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3444 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3445 between bpos_covered and bpos_max. This fixes cursor display when
3446 several display strings follow each other.
3448 * .gdbinit (pgx): If the glyph's object is a string, display the
3449 pointer to string data, rather than the value of the string object
3450 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3452 * indent.c (Fvertical_motion): If the starting position is covered
3453 by a display string, return to one position before that, to avoid
3454 overshooting it inside move_it_to. (Bug#12930)
3456 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3458 * frame.h (struct frame): Remove display_preempted member

3461 * w32menu.c (pending_menu_activation): Remove since not
3463 (set_frame_menubar): Adjust user.
3464 * w32term.h (struct x_output): Drop outdated #if 0 code.

3467 Drop unused pending_menu_activation member.
3468 * xterm.h (struct x_output): Drop outdated #if 0 code.
3469 Use bitfields for explicit_parent, asked_for_visible,
3470 has_been_visible and net_wm_state_hidden_seen members.
3472 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3474 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3475 of a literal "/". (Bug#12955)
3476 (gl-stamp): Invoke fc.exe directly, not through cmd.
3478 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

3481 * dired.c: Assume HAVE_DIRENT_H.
3482 (NAMLEN): Remove, replacing with ...
3483 (dirent_namelen): New function. All uses changed. Use the GNU macro
3484 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3485 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3486 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3487 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3489 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3490 * ndir.h: Rename to ../nt/inc/dirent.h.
3491 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3492 Do not include <dirent.h>; no longer needed.
3493 * w32.c: Include <dirent.h> rather than "ndir.h".
3495 2012-11-23 Chong Yidong <cyd@gnu.org>
3497 * xftfont.c (xftfont_open): Remove duplicate assignment.
3499 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3501 * alloc.c (Fgarbage_collect): Unblock input after clearing
3502 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3503 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3504 * msdos.c (IT_frame_up_to_date): Use it here...
3505 * w32term.c (w32_frame_up_to_date): ...here...
3506 * xterm.c (XTframe_up_to_date): ...and here...
3507 * nsterm.m (ns_frame_up_to_date): ...but not here.
3508 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3510 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3511 Do not check whether GC is in progress.
3513 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3515 * xdisp.c (window_buffer_changed): New function.
3516 (update_menu_bar, update_tool_bar): Use it to
3517 simplify large 'if' statements.

3519 'tail' and 'frame' local variables.
3521 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3523 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3524 with Windows system header.
3526 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3528 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3529 * alloc.c: Assume unistd.h exists.
3530 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
3531 * sysdep.c (get_current_dir_name): Assume getcwd exists.

3545 * emacs.c (main): Set the G_SLICE environment variable for all
3546 Cygwin builds, not just GTK builds. See
3547 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3549 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3551 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3552 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3553 Define for the MSVC compiler.
3555 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3557 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3558 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3559 dostounix_filename. Prevents crashes down the road, because
3560 dostounix_filename assumes it gets a unibyte string.
3561 Reported by Michel de Ruiter <michel@sentient.nl>, see

3593 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3594 (syms_of_eval): Remove corresponding defsubr.
3595 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3597 2012-11-19 Daniel Colascione <dancol@dancol.org>
3599 * w32fns.c (Fx_file_dialog):
3600 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3601 cygwin_convert_file_name*.
3603 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3604 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3606 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3608 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3610 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3612 * w32select.c: Include w32common.h before w32term.h, so that
3613 windows.h gets included before w32term.h uses some of its
3614 features, see below.
3616 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3618 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

3629 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3630 Needed following 2012-10-20 change. (Bug#12902)
3632 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3634 * w32proc.c (waitpid): Remove unused label get_result.
3636 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3638 * makefile.w32-in (SYSWAIT_H): New macro.
3639 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3640 ($(BLD)/sysdep.$(O)): Update dependencies.

3646 * emacs.c, term.c (O_RDWR): Remove.
3647 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3648 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3649 * nsterm.m: Assume <fcntl.h> exists.
3650 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3651 (create_pty, Fmake_network_process, server_accept_connection)
3652 (wait_reading_process_output, init_process_emacs):
3654 (wait_reading_process_output): Put in a special case for WINDOWSNT
3655 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3656 It's not clear this is needed, but it's a more-conservative change.
3657 (create_process): Assume FD_CLOEXEC.
3658 (create_process, create_pty): Assume O_NOCTTY.
3659 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3660 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3661 Omit if not DOS_NT, since F_GETFL is not defined there.
3662 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3663 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3665 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3666 lack it, since gnulib guarantees this.
3667 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3669 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3671 * w32.c (faccessat): Pretend that directories have the execute bit
3672 set. Emacs expects that, e.g., in files.el:cd-absolute.
3674 * w32proc.c (create_child): Don't clip the PID of the child
3675 process to fit into an Emacs integer, as this is no longer a
3677 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3678 reaping only the process specified by PID argument, if that is
3679 positive. Use PID instead of dead_child to know which process to
3680 reap. Wait for the child to die only if WNOHANG is not in
3682 (sys_select): Don't set dead_child.
3684 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3685 as it is no longer needed.
3687 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3689 (record_child_status_change): Remove the setting of
3690 record_at_most_one_child for the !WNOHANG case.
3692 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3694 Fix problems in ns port found by static checking.
3695 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3696 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3697 not to process group.
3698 (ns_select): Use emacs_write, not write, as that's more robust
3699 in the presence of signals.
3700 (fd_handler:): Check for read errors.
3702 2012-11-16 Glenn Morris <rgm@gnu.org>
3704 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)

3712 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3713 use the same value of thread handle.
3714 (start_timer_thread): If the timer thread exited (due to error),
3715 clean up by closing the two handles it used. Duplicate the caller
3716 thread's handle here, so it gets duplicated only once, when
3717 launching the timer thread. Set priority of the timer thread, not
3719 (getitimer): Don't duplicate the caller thread's handle here.
3722 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3724 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3727 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3729 Remove no-longer-used pty_max_bytes variable.
3730 * process.c (pty_max_bytes): Remove; unused.
3731 (send_process): Do not set it.
3733 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3735 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3736 Update dependencies.
3738 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3740 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3741 This follows up on the 2012-09-29 patch that removed indirection
3742 for the 'function' field. Reported by Sergey Vinokurov in
3743 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3745 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3747 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3748 different name, as the MS runtime does not have such a function,
3749 and probably never will.) All callers changed. Ignore DIRFD
3750 value if PATH is an absolute file name, to match Posix spec
3751 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3754 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3756 * xdisp.c (echo_area_display, redisplay_internal):
3757 Omit redundant check whether frame_garbaged is set.
3759 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3761 Use faccessat, not access, when checking file permissions (Bug#12632).
3762 This fixes a bug that has been present in Emacs since its creation.
3763 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3764 which must set some sort of record. (Torek's bug report was against
3765 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3766 same common flaw.) See Torek's Usenet posting
3767 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3768 Posted: Fri Apr 8 14:18:56 1983.
3769 * Makefile.in (LIB_EACCESS): New macro.
3771 * callproc.c (init_callproc):
3772 * charset.c (init_charset):
3773 * fileio.c (check_existing, check_executable, check_writable)
3775 * lread.c (openp, load_path_check):
3776 * process.c (allocate_pty):
3778 Use effective UID when checking permissions, not real UID.
3779 * callproc.c (init_callproc):
3780 * charset.c (init_charset):
3781 * lread.c (load_path_check, init_lread):
3782 Test whether directories are accessible, not merely whether they exist.
3783 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3784 * fileio.c (check_existing, check_executable, check_writable)
3786 Use symbolic names instead of integers for the flags, as they're
3788 (check_writable): New arg AMODE. All uses changed.
3789 Set errno on failure.
3790 (Ffile_readable_p): Use faccessat, not stat + open + close.
3791 (Ffile_writable_p): No need to call check_existing + check_writable.
3792 Just call check_writable and then look at errno. This saves a syscall.
3793 dir should never be nil; replace an unnecessary runtime check
3794 with an eassert. When checking the parent directory of a nonexistent
3795 file, check that the directory is searchable as well as writable, as
3796 we can't create files in unsearchable directories.
3797 (file_directory_p): New function, which uses 'stat' on most platforms
3798 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3799 (Ffile_directory_p, Fset_file_times): Use it.
3800 (file_accessible_directory_p): New function, which uses a single
3801 syscall for efficiency.
3802 (Ffile_accessible_directory_p): Use it.
3803 * xrdb.c (file_p): Use file_directory_p.
3804 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3805 * lread.c (openp): When opening a file, use fstat rather than
3806 stat, as that avoids a permissions race. When not opening a file,
3807 use file_directory_p rather than stat.
3808 (dir_warning): First arg is now a usage string, not a format.
3809 Use errno. All uses changed.
3810 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3811 that merely introduced a race.
3812 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3813 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3814 and similarly for the other O_* flags.
3815 * w32.c (sys_faccessat): Rename from sys_access and switch to
3816 faccessat's API. All uses changed.
3817 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3818 (magic_db): Rename from magic_file_p.
3819 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3820 char *, so that we don't have to test for file existence
3821 separately from opening the file for reading. This removes a race
3822 fixes a permission-checking problem, and simplifies the code.
3824 (file_p): Remove; no longer needed.
3826 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3828 Omit glyphs initialization at startup.
3829 * dispnew.c (glyphs_initialized_initially_p): Remove.
3830 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3831 (Fredraw_frame): Move actual code from here...
3832 (redraw_frame): ...to here. Add eassert. Adjust comment.
3833 (Fredraw_display): Use redraw_frame.
3834 * xdisp.c (clear_garbaged_frames): Likewise.
3836 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3838 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3839 passed to pint2str and pint2hrstr to be at most the size of the
3840 frame's decode_mode_spec_buffer. This avoids crashes with very
3841 large values of FIELD_WIDTH argument to decode_mode_spec.
3844 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3846 Fix a race with verify-visited-file-modtime (Bug#12863).
3847 Since at least 1991 Emacs has ignored an mtime difference of no
3848 more than one second, but my guess is that this was to work around
3849 file system bugs that were fixed long ago. Since the race is
3850 causing problems now, let's remove that code.
3851 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3852 whose time stamp is off by no more than a second. Insist that the
3853 file time stamps match exactly.
3855 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3857 * frame.h (struct frame): Convert external_tool_bar member to
3858 1-bit unsigned bitfield.
3859 * termhooks.h (struct terminal): Remove mouse_moved member since
3860 all users are long dead. Adjust comment on mouse_position_hook.
3862 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3864 Simplify by using FOR_EACH_FRAME here and there.
3865 * frame.c (next_frame, prev_frame, other_visible_frames)
3866 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3867 * w32term.c (x_window_to_scroll_bar): Likewise.
3868 * window.c (window_list): Likewise.
3869 * xdisp.c (x_consider_frame_title): Likewise.
3870 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3871 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3872 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3873 * xmenu.c (menubar_id_to_frame): Likewise.
3874 * xselect.c (frame_for_x_selection): Likewise.
3875 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3876 (x_window_to_menu_bar): Likewise.
3877 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3879 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3881 * data.c (Qdefalias_fset_function): Now static.
3883 Another tweak to vectorlike_header change.
3884 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3885 Remove, and replace all uses with ...
3886 (next_in_free_list, set_next_in_free_list):
3887 New functions, which respect C's aliasing rules better.
3889 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3891 * window.c (list4i): Rename from 'quad'. All uses changed.
3892 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3894 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3896 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3897 warning about mixing declarations and code in ISO C90.
3899 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3901 * window.c (Fsplit_window_internal): Set combination limit of
3902 new parent window to t iff Vwindow_combination_limit is t;
3903 fixing a regression introduced with the change from 2012-09-22.
3904 (Fset_window_combination_limit): Fix doc-string.
3906 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3908 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3909 amount when the scroll margins are too large. When scrolling
3910 backwards in the buffer, give up if cannot reach point or the
3911 scroll margin within a reasonable number of screen lines.
3912 Fixes point position in window under scroll-up/down-aggressively when
3913 point is positioned many lines beyond the window top/bottom.
3916 * ralloc.c (relinquish): If real_morecore fails to return memory
3917 to the system, don't crash; instead, leave the last heap
3918 unchanged and return. (Bug#12774)
3920 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3922 * lisp.h (AUTOLOADP): New macro.
3923 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3924 * data.c (Ffset): Remove special ad-advice-info handling.
3925 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3927 (Finteractive_form): Simplify.
3928 (Fquo): Don't insist on having at least 2 arguments.
3929 (Qdefalias_fset_function): New var.
3931 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3933 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
3935 * nsfont.m (Qcondensed, Qexpanded): New variables.
3936 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
3937 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3939 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3941 Fix recently introduced crash on MS-Windows (Bug#12839).
3942 * w32term.h (struct scroll_bar): Use convenient header.
3943 (SCROLL_BAR_VEC_SIZE): Remove.
3944 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3946 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3948 Tweak last vectorlike_header change.
3949 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3950 vectorlike object on the free list. This is introduced to avoid
3951 some (but not all) pointer casting and aliasing problems, see
3952 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3953 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3955 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3957 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3959 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3960 been removed, so remove them here also.
3962 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3964 * doc.c (Fdocumentation): Handle new property
3965 dynamic-docstring-function to replace the old ad-advice-info.
3967 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
3969 * fns.c (Qeql, hashtest_eq): Now static.
3971 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3973 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
3974 * fns.c (hashfn_eq, hashfn_eql, sxhash):
3975 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
3976 * buffer.c (compare_overlays): Use XLI rather than XHASH.
3978 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
3980 Use same hash function for hashfn_profiler as for hash_string etc.
3981 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
3982 * lisp.h (sxhash_combine): New inline function, with the contents
3983 of the old SXHASH_COMBINE.
3984 * profiler.c (hashfn_profiler): Use it, instead of having a
3985 special hash function containing a comparison that always yields 1.
3987 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3989 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3990 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3991 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3994 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3996 * image.c (xpm_make_color_table_h): Fix compiler error because
3997 make_hash_table changed.
3999 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4001 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4003 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4005 Use ad-hoc comparison function for the profiler's hash-tables.
4006 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4007 (make_log): Use them.
4008 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4009 call Fequal any more.
4010 (Ffunction_equal): New function.
4011 (cmpfn_profiler, hashfn_profiler): New functions.

4018 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4019 (hash_lookup, hash_remove_from_table): Move assertion checking of
4020 hashfn result here. Check hash-equality before calling cmpfn.

4027 * print.c (print_object): Adjust to new hash-table struct.
4028 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
4030 2012-11-08 Eli Zaretskii <eliz@gnu.org>
4032 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4033 value of w32-scroll-lock-modifier is neither nil nor one of the
4034 known key modifiers. (Bug#12806)
4036 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4038 Shrink struct vectorlike_header to the only size field.
4039 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4041 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4042 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4043 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4044 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4045 information from the vector header. Adjust comment.
4046 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
4047 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
4049 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.

4055 (enum mem_type): Adjust comment.
4056 (NEXT_IN_FREE_LIST): New macro.
4057 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
4058 (Fmake_bool_vector): Likewise.
4059 (struct large_vector): New type to represent allocation unit for
4060 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4061 (large_vectors): Change type to struct large_vector.
4062 (allocate_vector_from_block): Simplify.
4063 (PSEUDOVECTOR_NBYTES): Replace with...
4064 (vector_nbytes): ...new function. Adjust users.
4065 (sweep_vectors): Adjust processing of large vectors.
4066 (allocate_vectorlike): Likewise.
4067 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4068 Add easserts. Adjust XSETPVECTYPESIZE usage.
4069 (allocate_buffer): Use BUFFER_PVEC_INIT.
4070 (live_vector_p): Adjust to match large vector.
4071 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4072 * buffer.h (struct buffer): Add next member.
4073 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4075 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
4076 * fns.c (internal_equal): Adjust to match enum pvec_type change.
4077 (copy_hash_table): Adjust to match vector header change.
4078 * lread.c (defsubr): Use XSETPVECTYPE.
4079 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
4080 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
4081 (xvecsize): New command.
4083 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4085 * keyboard.c (event_to_kboard): Do not dereference
4086 frame_or_window field of SELECTION_REQUEST_EVENT
4087 and SELECTION_CLEAR_EVENT events (Bug#12814).
4088 * xterm.h (struct selection_input_event): Adjust comment.
4090 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4092 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4093 such as Scroll Lock, if the respective keys are treated as
4094 function keys, not as modifiers. This avoids destroying non-ASCII
4095 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4097 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4099 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4101 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4103 Restore some duplicate definitions (Bug#12814).
4104 This undoes part of the 2012-11-03 changes. Some people build
4105 with plain -g rather than with -g3, and they need the duplicate
4106 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4107 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4108 Define as macros, as well as as enums or as constants.
4110 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4112 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4113 to keypad keys (Bug#12816).
4115 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4117 Minor adjustments of recently-changed frame functions.
4118 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4119 known to be a frame (we're in the FRAMEP branch).
4120 * lisp.h (Qframep): Remove decl. frame.h declares this.
4121 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4122 since they're meant for Lisp fixnum values.
4124 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4126 * window.c (Fwindow_combination_limit): Revert to the only
4127 required argument and adjust docstring as suggested in
4128 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4129 by Martin Rudalics <rudalics@gmx.at>.
4131 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4133 Widely used frame validity and checking functions.
4134 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.

4138 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
4139 (Fframe_pointer_visible_p): Use decode_any_frame.
4140 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
4141 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
4142 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
4143 (Fframe_focus): Likewise. Allow zero number of arguments.
4145 (frame_buffer_list, frame_buffer_predicate): Remove.
4146 * lisp.h (frame_buffer_predicate): Remove prototype.
4147 * buffer.c (Fother_buffer): Use decode_any_frame.
4148 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4149 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4150 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4151 (Fclose_font, Ffont_info): Use decode_live_frame.
4152 * fontset.c (check_fontset_name): Likewise.
4153 * terminal.c (Fframe_terminal): Likewise.
4154 * w32fns.c (check_x_frame): Likewise.
4155 * window.c (Fminibuffer_window, Fwindow_at)
4156 (Fcurrent_window_configuration): Likewise.
4157 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
4158 Likewise. Allow zero number of arguments. Adjust docstring.
4159 * dispnew.c (Fredraw_frame): Likewise.
4160 * xfaces.c (frame_or_selected_frame): Remove.
4161 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4162 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4163 (Fframe_face_alist): Use decode_live_frame.
4164 * xfns.c (check_x_frame): Likewise.
4166 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4168 * window.c (quad): New function.
4169 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4170 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4171 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4172 (Fwindow_line_height): Use it.
4173 (Fwindow_fringes): Use list3.
4174 (Fwindow_scroll_bars): Use list4.
4175 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4176 (Fwindow_combination_limit): Allow zero number of arguments.
4178 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4180 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4182 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4183 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4184 file descriptor 2 for standard error. (Bug#12805)
4186 2012-11-05 Chong Yidong <cyd@gnu.org>
4188 * process.c (wait_reading_process_output): Revert previous change.
4190 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4192 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4193 This removes code that has been obsolete since around 1990.
4194 * callproc.c (Fcall_process):
4196 * process.c (create_process):
4197 * term.c (dissociate_if_controlling_tty):
4198 Assume setsid exists.
4199 * callproc.c (child_setup): Assume setpgid exists and behaves as
4200 per POSIX.1-1988 or later.
4201 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4202 * emacs.c (shut_down_emacs):
4203 * sysdep.c (sys_suspend, init_foreground_group):
4204 Assume getpgrp behaves as per POSIX.1-1998 or later.
4205 * msdos.c (setpgrp): Remove.
4206 (tcgetpgrp, setpgid, setsid): New functions.
4207 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4208 * term.c (no_controlling_tty): Remove; unused.
4209 * w32proc.c (setpgrp): Remove.
4210 (setsid, tcgetpgrp): New functions.
4212 Simplify by assuming __fpending.
4213 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4214 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4215 Do not assume that __fpending's result fits in int.
4217 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4219 Remove EMACS_OUTQSIZE+sleep hack.
4220 * dispnew.c (update_frame_1): Remove hack for terminals slower
4221 than 2400 bps, which throttled Emacs by having it sleep.
4222 This code hasn't worked since at least 2007, when the multi-tty stuff
4223 was added, and anyway those old terminals are long dead.
4224 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4225 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4227 Fix data-loss with --version (Bug#9574).
4228 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4229 as we can't assume that emacs_strerror is initialized, and strerror
4230 is good enough here.
4231 (main): Invoke atexit earlier, to catch earlier instances of
4232 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4234 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4236 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4237 (keyDown): Remap keypad keys to X11 virtual key codes.
4239 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4241 Fix data-loss with --batch (Bug#9574).
4242 * emacs.c: Include <close-stream.h>.
4243 (close_output_streams): New function.
4244 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4245 and handles errors appropriately.
4246 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4249 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4250 The symptom is a diagnostic "GLib-WARNING **: In call to
4251 g_spawn_sync(), exit status of a child process was requested but
4252 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4253 waitpid(), so exit status can't be returned." The diagnostic
4254 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4255 The real bug is a race condition between Emacs and glib: Emacs
4256 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4257 so that glib can't find it. Work around the bug by invoking
4258 waitpid only on subprocesses that Emacs itself creates.
4259 * process.c (create_process, record_child_status_change):
4260 Don't use special value -1 in pid field, as the caller now must
4261 know the pid rather than having the callee infer it.
4262 The inference was sometimes incorrect anyway, due to another race.
4263 (create_process): Set new 'alive' member if child is created.
4264 (process_status_retrieved): New function.
4265 (record_child_status_change): Use it.
4266 Accept negative 1st argument, which means to wait for the
4267 processes that Emacs already knows about. Move special-case code
4268 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4269 processes that have already been waited for, by testing and
4270 clearing new 'alive' member.
4271 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4272 now does this internally.
4273 (handle_child_signal): Let record_child_status_change do all
4274 the work, since we do not want to reap all exited child processes,
4275 only the child processes that Emacs itself created.
4276 * process.h (Lisp_Process): New boolean member 'alive'.
4278 Omit duplicate definitions no longer needed with gcc -g3.
4279 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4280 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4281 Define only as macros. There's no longer any need to also define
4282 these symbols as enums or as constants, since we now assume
4283 gcc -g3 when debugging.
4285 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4287 * lisp.mk: Adjust comments to the fact that term/internal is now
4288 loaded from loadup.el.
4290 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4291 (msdos_fatal_signal): New function.
4292 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4295 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4296 for GCC versions before 4.
4297 (emacs_raise): Define to call msdos_fatal_signal.
4299 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4300 iterator when starting in the middle of a display or overlay
4303 2012-11-03 Chong Yidong <cyd@gnu.org>
4305 * process.c (wait_reading_process_output): Clean up the last
4308 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4310 * process.c (wait_reading_process_output): Avoid a race condition
4311 with SIGIO delivery (Bug#11536).
4313 2012-11-03 Chong Yidong <cyd@gnu.org>
4315 * buffer.c (cursor_type): Untabify docstring.
4317 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4319 * frame.h (struct frame): Drop can_have_scroll_bars member
4320 which is meaningless for a long time. Adjust comments.
4321 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4322 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4324 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4326 * window.c (decode_next_window_args): Update window arg after
4327 calling decode_live_window and so fix crash reported at
4328 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4329 by Juanma Barranquero <lekktu@gmail.com>.
4330 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4331 * font.c (Ffont_at): Likewise.
4333 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4335 * widget.c (resize_cb): New function.
4336 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4337 (EmacsFrameResize): Check if all is up to date before changing frame
4340 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4342 Implement backtrace output for fatal errors on MS-Windows.
4343 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4344 (BACKTRACE_LIMIT_MAX): New macro.
4345 (w32_backtrace): New function.
4346 (emacs_abort): Use w32_backtrace when the user chooses not to
4347 attach a debugger. Update the text of the abort dialog.
4349 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4351 Window-related stuff cleanup here and there.
4352 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4353 Use decode_any_window.
4354 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4355 * xdisp.c (Fformat_mode_line): Likewise.
4356 * font.c (Ffont_at): Use decode_live_window.
4357 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4358 * window.c (decode_next_window_args): Likewise.
4359 (decode_any_window): Remove static.
4360 * window.h (decode_any_window): Add prototype.
4361 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4362 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4365 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4367 Remove pad from struct input_event.
4368 * termhooks.h (struct input_event): Remove padding field.
4370 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4371 member is never cons for a long time. Adjust comment.
4372 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4373 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4374 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4375 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4377 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4379 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4381 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4383 Fix crash when using Emacs as commit editor for git (Bug#12697).
4384 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4385 and it is configured in conf_post.h.
4386 (Fcall_process): Don't invoke both setsid and setpgid; the former
4387 is enough, if it exists.
4388 * callproc.c (Fcall_process, child_setup):
4389 * process.c (create_process): Use setpgid.
4390 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4392 * dispnew.c (init_display): Initialize the foreground group
4393 if we are running a tty display.
4394 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4395 * lisp.h (init_foreground_group): New decl.
4396 * sysdep.c (inherited_pgroup): New static var.
4397 (init_foreground_group, tcsetpgrp_without_stopping)
4398 (narrow_foreground_group, widen_foreground_group): New functions.
4399 (init_sys_modes): Narrow foreground group.
4400 (reset_sys_modes): Widen foreground group.
4402 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4404 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4406 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4408 * minibuf.c (read_minibuf): Restore current buffer since
4409 choose_minibuf_frame calling Fset_frame_selected_window may
4410 change it (Bug#12766).
4412 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4414 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4416 2012-10-30 Kenichi Handa <handa@gnu.org>
4418 * font.c (Ffont_at): If WINDOW is specified and it is not
4419 displaying the current buffer, signal an error.
4421 2012-10-29 Daniel Colascione <dancol@dancol.org>
4423 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4424 In preparation for fixing bug#12739, move these functions from
4427 * coding.h, coding.c: ... to here, and compile them only when
4428 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4429 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4431 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4433 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4434 (timer_loop, getitimer, setitimer): Use it instead of
4435 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4437 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4440 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4442 * nsterm.m (NO_APPDEFINED_DATA): New define.
4443 (last_appdefined_event_data): New variable
4444 (last_appdefined_event): Remove.
4445 (ns_select): Initialize t from last_appdefined_event_data instead
4446 of [last_appdefined_event data1].
4447 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4448 remove last_appdefined_event (Bug#12698).
4450 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4452 * frame.c (x_set_font): Catch internal error.
4454 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4456 Avoid overflow in w32 implementation of interval timers.
4457 When possible, for ITIMER_PROF count only times the main thread
4459 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4460 'volatile ULONGLONG' types. All the other data which was
4461 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4462 (GetThreadTimes_Proc): New typedef.
4463 (w32_get_timer_time): New function, returns a suitable time value
4465 (timer_loop): Enter critical section when accessing ULONGLONG
4466 values of the itimer_data struct, as these accesses are no longer
4467 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4468 Remove unused variable.
4469 (init_timers): Initialize s_pfn_Get_Thread_Times.
4470 (start_timer_thread): Don't assign itimer->caller_thread here.
4471 (getitimer): Assign itimer->caller_thread here.
4472 (setitimer): Always call getitimer to get the value of ticks_now.
4473 (sys_spawnve): Avoid compiler warning about format mismatch.
4475 2012-10-26 Eli Zaretskii <eliz@gnu.org>
4477 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4478 mouse movement events if the menu bar is active. This avoids
4479 producing a busy "hour-glass" cursor by Windows if the mouse
4480 pointer is positioned over a tooltip shown for some menu item.
4482 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4484 Don't assume process IDs fit in int.
4485 * emacs.c (shut_down_emacs) [!DOS_NT]:
4486 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4487 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4488 Use pid_t, not int, to store process IDs, as 'int'
4489 is not wide enough on a few platforms (e.g., AIX and IRIX).
4491 2012-10-23 Kenichi Handa <handa@gnu.org>
4493 The following change is to make face-font-rescale-alist work
4494 correctly for non-ASCII fonts.
4496 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4497 (font_open_for_lface): Handle Vface_font_rescale_alist.
4499 2012-10-23 Chong Yidong <cyd@gnu.org>
4501 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4503 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
4505 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
4507 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
4509 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
4512 2012-10-21 Glenn Morris <rgm@gnu.org>
4514 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4516 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4518 Port to OpenBSD 5.1.
4519 * frame.c (Fmouse_position, Fmouse_pixel_position):
4520 * xdisp.c (produce_stretch_glyph):
4521 Declare local vars only when they're needed.
4522 This is clearer and avoids a warning on OpenBSD about unused vars.
4523 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
4524 This is safer, and avoids OpenBSD warnings about unused vars.
4525 * keyboard.c (record_menu_key): Remove unnecessary decl.
4526 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4527 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4528 as our definition clashes with OpenBSD's.
4529 * xfaces.c (load_face_colors, check_lface_attrs)
4530 (get_lface_attributes_no_remap, get_lface_attributes)
4531 (lface_fully_specified_p, x_supports_face_attributes_p)
4532 (tty_supports_face_attributes_p, face_fontset, realize_face)
4533 (realize_x_face, realize_tty_face):
4534 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4535 merely Lisp_Object *. This is more informative and avoids
4536 a warning on OpenBSD about accessing beyond an object's size.
4538 2012-10-20 Chong Yidong <cyd@gnu.org>
4540 * lread.c (Fload): Doc fix (Bug#12592).
4542 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
4544 * font.c (Ffont_at): Fix previous change.
4546 2012-10-19 Eli Zaretskii <eliz@gnu.org>
4548 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
4549 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
4552 * alloc.c (NSTATICS): Decrease to 0x800.
4554 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
4556 * fns.c (Fnreverse): Include the problem element when signaling an
4559 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
4561 * nsterm.m (ns_select): Check writefds before call to
4562 FD_ISSET (Bug#12668).
4564 2012-10-18 Daniel Colascione <dancol@dancol.org>
4566 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4567 (staticpro): If we run out of staticpro slots, die with an
4568 informative error instead of just calling emacs_abort.
4570 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4572 Fix two flaws reported by Dmitry Antipov.
4573 * window.c (Ftemp_output_buffer_show): Remove.
4574 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
4575 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
4577 2012-10-17 Eli Zaretskii <eliz@gnu.org>
4579 * makefile.w32-in ($(BLD)/w32.$(O)):
4580 ($(BLD)/vm-limit.$(O)):
4582 ($(BLD)/unexw32.$(O)):
4583 ($(BLD)/fileio.$(O)):
4584 ($(BLD)/dispnew.$(O)): Update dependencies.
4586 * w32term.h (w32_initialize_display_info, initialize_w32_display):
4589 * w32proc.c: Include ctype.h.
4591 * w32.h (init_environment, check_windows_init_file)
4592 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
4593 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
4594 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
4595 (sys_link): Add prototypes.
4597 * w32.c: Include w32select.h.
4598 (sys_access, e_malloc, sys_select): Add prototypes.
4599 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
4601 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
4603 * unexw32.c: Include lisp.h and w32.h.
4605 * term.c [WINDOWSNT]: Include w32term.h.
4607 * process.c [WINDOWSNT]: Add prototype of sys_select.
4609 * fileio.c [WINDOWSNT]: Include w32.h.
4611 * dispnew.c [WINDOWSNT]: Include w32.h.

4669 * image.c (init_tiff_functions, init_imagemagick_functions)
4670 (init_svg_functions): Fix cygw32 build break by using these
4671 functions only when WINDOWSNT _and_ HAVE_NTGUI.

4692 Fix some stat-related races.
4693 * fileio.c (Fwrite_region): Avoid race condition if a file is

4726 * fileio.c (check_existing): New function.
4727 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
4728 instead of calling 'stat', when what's needed is to check whether
4729 a file exists. This avoids expensive system calls on MS-Windows.
4732 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
4734 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

4824 (detect_input_pending_run_timers):
4825 * process.c (wait_reading_process_output):
4826 Use unsigned for counter where wraparound-on-overflow is desired,
4827 since unsigned is guaranteed to have that behavior and signed is not.
4828 (read_char): Use ptrdiff_t for string length.
4829 (get_input_pending): Remove first argument, since it was always
4830 the same pointer-to-int (now pointer-to-boolean) &input_pending,
4831 and behave as if it had that value. Return new value of
4832 input_pending. All callers changed.
4833 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4834 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
4836 * keymap.c (push_key_description): Omit last arg, which was always 1.
4837 All callers changed.
4839 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
4841 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

4857 Don't include termopts.h.
4859 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
4861 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
4863 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4865 * commands.h (immediate_quit): Remove duplicate decl.
4867 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
4869 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

4872 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
4874 2012-10-09 Eli Zaretskii <eliz@gnu.org>
4876 * w32fns.c (w32_last_error): Change the return value to DWORD, to
4877 match what GetLastError returns. Explain why the function is
4880 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4881 'is_tooltip_frame', to avoid confusion with its global namesake.
4883 2012-10-08 Daniel Colascione <dancol@dancol.org>
4885 * xdisp.c (start_hourglass): Call w32_note_current_window when
4886 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4887 build that caused Emacs to display the hourglass cursor forever.
4889 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4890 which is broken under remote desktop, calculate the number of
4891 colors available for a display based on the display's number of
4892 planes and number of bits per pixel per plane. (bug#10397).
4894 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4896 * nsfont.m (Vfonts_in_cache): New variable.
4897 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4898 are used. Add cached fonts to Vfonts_in_cache.
4899 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4901 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4903 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4905 (FONT_H): Define after FRAME_H.
4906 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4907 Update dependencies.
4909 * w32term.c: Remove leftover declaration of keyboard_codepage.
4911 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4913 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4914 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4915 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4916 (GLOBAL_SOURCES): Add cygw32.c.
4917 ($(BLD)/unexw32.$(O)):
4919 ($(BLD)/w32console.$(O)):
4920 ($(BLD)/w32fns.$(O)):
4921 ($(BLD)/w32heap.$(O)):
4922 ($(BLD)/w32menu.$(O)):
4923 ($(BLD)/w32proc.$(O)): Add w32common.h.
4925 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4927 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4929 2012-10-08 Daniel Colascione <dancol@dancol.org>
4931 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4932 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4933 accidental message numbering hole. Change other messages to
4936 * w32select.h (HAVE_W32SELECT): Remove.
4938 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4939 w32common.h instead of w32heap.h.
4941 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4942 (get_allocation_unit, get_processor_type, get_w32_major_version)
4943 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4944 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4945 (OS_NT, os_subtype, cache_system_info): Move declarations to
4948 * w32heap.c: Include w32common.h.
4949 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4950 (w32_minor_version, w32_build_number, w32_subtype):
4951 Remove duplicate definitions.
4953 * w32fns.c: Include w32common.h; include w32heap.h only in
4956 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4957 Use `report_file_error' instead of `error' in order to better
4958 inform users of what went wrong. Increase NTGUI_UNICODE file
4959 dialog box file name length to 32k, the maximum allowed by the NT
4962 * w32common.h: New file.
4963 (ROUND_UP, ROUND_DOWN, get_page_size)
4964 (get_allocation_unit, get_processor_type, get_w32_major_version)
4965 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4966 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4967 (OS_NT, os_subtype, cache_system_info): Move here.
4969 * unexw32.c, unexcw.c: Include w32common.h.
4971 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4972 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4973 to call syms_of_w32select.
4975 * cygw32.h: Remove obsolete EXFUN declarations.
4977 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

4980 of w32inevt.o from SOME_MACHINE_OBJECTS.
4982 2012-10-08 Daniel Colascione <dancol@dancol.org>
4984 * image.c: Permanent fix for JPEG compilation issue --- limit
4985 jpeglib `boolean' redefinition to Cygwin builds.
4987 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4989 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4991 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4994 2012-10-08 Daniel Colascione <dancol@dancol.org>
4996 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4997 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4998 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4999 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5000 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5001 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5002 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5003 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5004 now a supported configuration.
5006 * Makefile.in: consolidate image variables into LIBIMAGE; add
5007 W32_OBJ and W32_LIBS. Compile new files.
5010 (_DebPrint) declare tracing facility for W32 debugging. We need
5011 to unify tracing later.
5013 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5014 unconditional use of W32 Unicode functions. Cygwin runs only on
5015 100% Unicode operating systems.
5017 * cygw32.c: New file. Define Cygwin-specific facilities.
5018 (Fcygwin_convert_path_to_windows)
5019 (Fcygwin_convert_path_from_windows): New user functions for
5020 accessing Cygwin path-munging routines.
5022 * cygw32.h: New file.
5023 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5024 UTF-16LE strings temporarily inside non-Lisp-visible string
5027 (w32_strerror): Just what it says on the tin.
5029 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5030 also run for Cygwin; both systems have the same problem with using
5031 GUI facilities in a forked child. Also call syms_of_cygw32,
5032 syms_of_w32select in correct places.
5034 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5035 needs fork-then-exec for daemon launching.
5037 * font.h: Include frame.h.
5039 * image.c: Use the image library cache machinery only when we're
5040 compiling for native WINDOWSNT; Cygwin can use shared libraries
5041 like any other Unixlike system.
5043 * keyboard.c: Clarify a comment regarding the input loop.
5045 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5046 functions directly instead of trying to detect at runtime that our
5047 host operating system supports them. We make this change for two
5048 reasons: Cygwin lacks support for the multibyte character
5049 conversion functions used by the legacy menu code, and Cygwin
5050 never needs to rely on non-Unicode APIs.
5052 * unexw32.c (hinst): Declare extern.
5054 * w32.c: Change header order;
5055 (w32_strerror): Move to w32fns.c because we need it for
5056 non-WINDOWSNT builds.
5058 * w32.h: Add #error macro to make sure we don't include w32.h for
5059 Cygwin builds. Remove w32select declarations.
5061 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5062 w32fns.c. w32console.c is WINDOWSNT-only.
5064 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5065 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5067 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5068 (w32_major_version, w32_minor_version, w32_build_number)
5069 (os_subtype, sound_type): Define here
5070 (w32_defined_color): Make color parameter const for consistency
5071 with other _defined_color functions.
5072 (w32_createwindow): Unconditionally call w32_init_class instead of
5073 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5074 through the code is complex and unnecessary because class
5075 registration is practically free.
5076 (w32_name_of_message): New EMACSDEBUG-only function.
5077 (Fset_message_beep): Move here
5078 (Fx_open_connection): Require that the display name for Windows be
5079 "w32" for consistency, emacsclient disambiguation, and maybe, one
5080 day, multi-window-system support.
5081 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5082 Cygwin files for W32 GUI facilities, since these clearly don't
5083 expect Cygwin names.

5102 * w32select.c: Include string.h, stdio.h for Cygwin.
5103 * w32select.h: New File.
5105 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5107 (w32_message_fd): New variable. Under Cygwin, holds the file
5108 descriptor the system used to tell us about pending thread
5111 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5112 that prevented compilation under non-WINDOWSNT systems.
5114 (w32_initialize): Open /dev/windows and assign it to
5115 w32_message_fd. Provide w32 feature.
5117 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5118 (WM_EMACS_INPUT_READY): add.
5119 (prepend_msg, w32_message_fd): Declare globally.
5122 (keyboard_handle): Use only when WINDOWSNT.
5123 (notify_msg_ready): New function. Posts a message to the main
5124 thread's message queue under CYGWIN, which wakes up the main
5125 thread from select(2) by making the /dev/windows file descriptor
5126 ready. Under WINDOWSNT, it sets an event the same way the old
5129 (post, prepend_msg): Actually call notify_msg_ready instead of
5130 setting the input event directly.
5132 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5134 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5135 but it still has blocs in it, don't return it to the system,
5136 instead of aborting. (Bug#12402)
5138 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5140 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).

5173 Improve sys_siglist detection.
5174 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5175 defined as a macro, as is done in Solaris.
5176 (sys_siglist_entries): New macro.
5177 (save_strsignal): Use it.
5178 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5179 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5181 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5183 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5184 fullscreen/Fullscreen.
5186 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5187 tobar_height is new.
5189 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5190 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5191 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

5204 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5206 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5208 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5210 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5211 that time stamps of directories could also be changed.
5212 Don't request the too broad GENERIC_WRITE, only the more restrictive
5213 FILE_WRITE_ATTRIBUTES access rights.
5215 * fileio.c (Fset_file_times): Special-case ignoring errors for
5216 directories only on MSDOS, not on MS-Windows.
5218 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5220 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5222 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5224 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5225 see whether CreateFile failed.
5227 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5229 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5230 to avoid similar races.
5231 * keyboard.c (pending_signals): Now bool, not int.
5233 Port timers to OpenBSD, plus check for timer failures.
5234 OpenBSD problem reported by Han Boetes.
5235 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5237 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5238 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5239 like OpenBSD, which has timer_settime but does not declare it.
5240 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5241 whether to use itimerspec-related primitives. All uses of
5242 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5244 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5246 * profiler.c (handle_profiler_signal): Fix a malloc race
5247 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5249 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5251 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5253 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5255 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5256 consistent with the change in return value of 'safe_strsignal'.
5258 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5260 Prefer plain 'static' to 'static inline' (Bug#12541).

5262 (bidi_set_sor_type, bidi_push_embedding_level)
5263 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

5268 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5269 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5270 Now 'static', not 'static inline'.
5272 Count overruns when profiling; change units to ns.
5273 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5274 Give extra weight to samples after overruns, to attempt to count
5275 the time more accurately.
5276 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5277 the underlying primitives nominally do ns.
5278 (Fprofiler_cpu_start): Document the change. Mention that
5279 the sampling intervals are only approximate.
5281 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5283 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5285 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5286 case for the special 0 coding-system.
5288 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5289 (Fmake_overlay): Remove redundant tests.
5290 (fix_start_end_in_overlays): Remove redundant recentering.
5292 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5294 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5295 Update dependencies.
5297 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5299 Fix a malloc race condition involving strsignal.
5300 A signal can arrive in the middle of a malloc, and Emacs's signal
5301 handler can invoke strsignal, which can invoke malloc, which is
5302 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5303 Fix it by altering the signal handler so that it does not invoke
5305 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5306 * process.c (status_message): Use const pointer, in case strsignal
5307 is #defined to safe_strsignal.
5308 * sysdep.c (sys_siglist, init_signals): Always define and
5309 initialize a substitute sys_siglist if the system does not define
5310 one, even if HAVE_STRSIGNAL.
5311 (safe_strsignal): Rename from strsignal. Always define,
5312 using sys_siglist. Return a const pointer.
5313 * syssignal.h (safe_strsignal): New decl.
5314 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5316 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5318 * w32proc.c (timer_loop): Fix code that waits for timer
5319 expiration, to avoid high CPU usage.
5321 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5323 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5324 (sweep_weak_table): Remove redundant prototypes.
5326 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5328 * emacs.c: Move the inclusion of TERM_HEADER after including
5329 windows.h on WINDOWSNT. This avoids compilation problems with
5332 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5334 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5335 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5336 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5337 as the previous version used 'void *'.
5339 * ralloc.c (ROUNDUP): Fix last change.
5340 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5343 * w32proc.c <disable_itimers>: New static flag.
5344 (init_timers): Initialize it to zero, after creating the critical
5345 sections used by the timer threads.
5346 (term_timers): Set to 1 before deleting the critical sections.
5347 (getitimer, setitimer): If disable_itimers is non-zero, return an
5348 error indication without doing anything. Reported by Fabrice
5349 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5350 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5352 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5355 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5356 term_ntproc after all the other bookkeeping, to get timers working
5357 as long as possible.
5359 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5361 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5362 Suggested by Juri Linkov in
5363 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5365 Prefer plain 'static' to 'static inline' (Bug#12541).
5366 With static functions, modern compilers inline pretty well by
5367 themselves; advice from programmers often hurts as much as it helps.
5368 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5369 this change shrinks the text size of the Emacs executable by 1.1%
5370 without affecting CPU significantly in my benchmark.
5371 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

5447 Now 'static', not 'static inline'.
5450 (bidi_copy_it): Do the whole copy with a single memcpy.
5451 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
5453 Revert the FOLLOW-SYMLINKS change for file-attributes.
5454 Doing it right would require several changes to Tramp, and there's
5455 not enough time to get that tested before the freeze today.
5456 * dired.c (directory_files_internal, Ffile_attributes):
5459 * frame.c (x_report_frame_params): Port better to wider ints.
5460 Do not assume that EMACS_UINT is the same width as uprintmax_t,
5461 or that pointers can be printed in 15 decimal digits.
5462 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

5643 Suggested by Eli Zaretskii in
5644 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
5646 2012-09-30 Eli Zaretskii <eliz@gnu.org>
5648 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
5649 HAVE_TIMER_SETTIME is defined.
5651 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5653 Profiler improvements: more-accurate timers, overflow checks.
5654 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
5655 signal.h, setjmp.h. Include systime.h instead.
5656 (saturated_add): New function.

5663 All uses changed to store the new value.
5664 (handle_profiler_signal): Rename from sigprof_handler_1,
5665 for consistency with other handlers. Do not check whether
5666 cpu_log is a hash-table if garbage collecting, since it
5667 doesn't matter in that case.

5669 for consistency with other handlers.
5670 (setup_cpu_timer): New function, with much of what used to be in
5671 Fprofiler_cpu_start. Check for out-of-range argument.
5672 Prefer timer_settime if available, and prefer
5673 thread cputime clocks, then process cputime clocks, then
5674 monotonic clocks, to the old realtime clock. Use make_timeval
5675 to round more-correctly when falling back to setitimer.
5676 (Fprofiler_cpu_start): Use it.
5677 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5678 Don't assume that passing NULL as the 2nd argument of setitimer
5679 is the same as passing a pointer to all-zero storage.

5681 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5682 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5683 non-fatal signal handlers. Ignore SIGPROF on startup.
5684 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5685 in profiler.c, since sysdep.c now uses it.
5687 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

5742 * charset.c, charset.h (maybe_unify_char): Now static.
5743 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5744 Since this stuff is now private to charset.c, there's no need for
5745 a public macro and no need to inline by hand.

5817 (sigaction): Rewrite to call sys_signal instead of duplicating its
5819 (sys_kill): Improve commentary.
5821 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5822 consistency with a signature of a signal handler. All callers
5824 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5825 install term_ntproc as a signal handler for SIGABRT, as that
5826 should be done by the dumped Emacs.
5828 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5830 * w32select.c (term_w32select): Protect against repeated
5831 invocation by setting clipboard_owner to NULL after calling

5949 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5950 fatal_error_backtrace.

5968 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5969 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5970 wanted even on POSIXish hosts, and it doesn't work on Windows.
5972 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5974 * xterm.c (x_term_init): Call fixup_locale before and after calling
5975 gtk_init (Bug#12392).
5977 2012-09-23 Chong Yidong <cyd@gnu.org>
5979 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5980 Vdynamic_library_alist.
5982 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5983 (Fgnutls_available_p): Caller changed.
5985 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5986 (Flibxml_parse_xml_region): Likewise.
5988 * dispextern.h (struct image_type): Remove arg from init function.
5990 * image.c (Finit_image_library, lookup_image_type)
5991 (define_image_type): Remove now-unneeded second arg.
5992 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5993 (init_tiff_functions, init_gif_functions, init_svg_functions):
5994 Arglist and w32_delayed_load calling convention changed.
5995 (gs_type): Remove init_gs_functions; there is no such function.
5996 (valid_image_p, make_image): Fix caller to lookup_image_type.
5998 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6000 Simplify and avoid signal-handling races (Bug#12471).
6002 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6003 Avoid recursive loop if there's a fatal error in the function itself.
6004 * atimer.c (pending_atimers):
6005 * blockinput.h: Don't include "atimer.h"; no longer needed.
6006 (interrupt_input_pending): Remove. All uses removed.
6007 pending_signals now counts both atimers and ordinary interrupts.
6008 This is less racy than having three separate pending-signal flags.
6009 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6011 Rename from their upper-case counterparts BLOCK_INPUT,
6012 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6013 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6014 This makes it easier to access volatile variables more accurately.
6015 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6016 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6017 that's more reliable if the code is buggy and sets
6018 interrupt_input_blocked to a negative value. All uses changed.
6019 * atimer.c (deliver_alarm_signal):
6020 Remove. No need to deliver this to the parent; any thread can
6021 handle this signal now. All uses replaced by underlying handler.
6022 * atimer.c (turn_on_atimers):
6023 * dispnew.c (handle_window_change_signal):
6024 * emacs.c (handle_danger_signal):
6025 * keyboard.c (kbd_buffer_get_event):
6026 Don't reestablish signal handler; not needed with sigaction.
6027 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6029 Rework to avoid unnecessary accesses to volatile variables.
6030 (UNBLOCK_INPUT_TO): Now a function.
6031 (totally_unblock_input, unblock_input): New decls.
6032 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6033 (init_data): Remove. Necessary stuff now done in init_signal.
6034 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6035 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6036 (fatal_error_code): Remove; no longer needed.
6037 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6038 it doesn't always backtrace. All uses changed. No need to reset
6039 signal to default, since sigaction and/or die does that for us now.
6040 Use emacs_raise (FOO), not kill (getpid (), FOO).
6041 (main): Check more-accurately whether we're dumping.
6042 Move fatal-error setup to sysdep.c
6043 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6044 * gtkutil.c (xg_get_file_name, xg_get_font):
6045 Remove no-longer-needed signal-mask manipulation.
6046 * keyboard.c, process.c (POLL_FOR_INPUT):
6047 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6048 * keyboard.c (read_avail_input): Remove.
6049 All uses replaced by gobble_input.
6050 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6051 (kbd_buffer_store_event_hold, gobble_input):
6052 (record_asynch_buffer_change) [USABLE_SIGIO]:
6053 (store_user_signal_events):
6054 No need to mess with signal mask.
6055 (gobble_input): If blocking input and there are terminals, simply
6056 set pending_signals to 1 and return. All hooks changed to not
6057 worry about whether input is blocked.
6058 (process_pending_signals): Clear pending_signals before processing
6059 them, in case a signal comes in while we're processing.
6060 By convention callers now test pending_signals before calling us.
6061 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6062 New functions, to support changes to blockinput.h.
6063 (handle_input_available_signal): Now extern.
6064 (reinvoke_input_signal): Remove. All uses replaced by
6066 (quit_count): Now volatile, since a signal handler uses it.
6067 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6068 All callers changed. Block SIGINT only if not already blocked.
6069 Clear sigmask reliably, even if Fsignal returns, which it can.
6070 Omit unnecessary accesses to volatile var.
6071 (quit_throw_to_read_char): No need to restore sigmask.
6072 * keyboard.c (gobble_input, handle_user_signal):
6073 * process.c (wait_reading_process_output):
6074 Call signal-handling code rather than killing ourselves.
6075 * lisp.h: Include <float.h>, for...
6076 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6077 (pending_signals): Now volatile.
6078 (syms_of_data): Now const if IEEE floating point.
6079 (handle_input_available_signal) [USABLE_SIGIO]:
6080 (terminate_due_to_signal, record_child_status_change): New decls.
6081 * process.c (create_process): Avoid disaster if memory is exhausted
6082 while we're processing a vfork, by tightening the critical section
6084 (send_process_frame, process_sent_to, handle_pipe_signal)
6085 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6087 (send_process): No need for setjmp/longjmp any more, since the
6088 SIGPIPE stuff is now gone. Instead, report an error if errno
6090 (record_child_status_change): Now extern. PID and W are now args.
6091 Return void, not bool. All callers changed.
6092 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6093 Remove. All uses removed. This bug should be fixed now in a
6095 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6096 and record the child status change directly. This avoids the
6097 need to futz with the signal mask.
6098 (process_fatal_action): Move here from emacs.c.
6099 (emacs_sigaction_flags): New function, containing
6100 much of what used to be in emacs_sigaction_init.
6101 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6102 caught by emacs, to make races less likely.
6103 (deliver_process_signal): Rename from handle_on_main_thread.
6105 (BACKTRACE_LIMIT_MAX): Now at top level.
6106 (thread_backtrace_buffer, threadback_backtrace_pointers):
6108 (deliver_thread_signal, deliver_fatal_thread_signal):
6109 New functions, for more-accurate delivery of thread-specific signals.
6110 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6111 (deliver_arith_signal): Handle in this thread, not
6112 in the main thread, since it's triggered by this thread.
6113 (maybe_fatal_sig): New function.
6114 (init_signals): New arg DUMPING so that we can be more accurate
6115 about whether we're dumping. Caller changed.
6116 Treat thread-specific signals differently from process-general signals.
6117 Block all signals while handling fatal error; that's safer.
6118 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6120 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6121 Ignore SIGPIPE unless batch.
6122 (emacs_backtrace): Output backtrace for the appropriate thread,
6123 which is not necessarily the main thread.
6124 * syssignal.h: Include <stdbool.h>.
6125 (emacs_raise): New macro.
6126 * xterm.c (x_connection_signal): Remove; no longer needed
6127 now that we use sigaction.
6128 (x_connection_closed): No need to mess with sigmask now.
6129 (x_initialize): No need to reset SIGPIPE handler here, since
6130 init_signals does this for us now.
6132 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6134 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6135 background rect may be larger (Bug#12245).
6137 2012-09-23 Chong Yidong <cyd@gnu.org>
6139 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6141 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6143 * .gdbinit: Just stop at fatal_error_backtrace.
6144 See Stefan Monnier's request in
6145 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6146 Remove no-longer-used query of system type.
6148 2012-09-22 Chong Yidong <cyd@gnu.org>
6150 * search.c (Freplace_match): Doc fix (Bug#12325).
6152 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6154 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6155 (Fline_end_position): Doc fix.
6157 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6159 2012-09-22 Chong Yidong <cyd@gnu.org>
6161 * dispextern.h (struct image_type): Add new slot, storing a type
6162 initialization function.
6164 * image.c (define_image_type): Call the image initializer function
6165 if it is defined. Arguments and return value changed.
6166 (valid_image_p, make_image): Callers changed.
6167 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6168 (gif_type, imagemagick_type, svg_type, gs_type):
6169 Add initialization functions.
6170 (Finit_image_library): Call lookup_image_type.
6171 (CHECK_LIB_AVAILABLE): Macro deleted.
6172 (lookup_image_type): Call define_image_type here, rather than via
6173 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6174 (syms_of_image): Move define_image_type calls for xbm_type and
6175 pbm_type to lookup_image_type.
6177 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6179 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6180 'idle_timers' from here ...
6181 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6182 lists, to avoid infloops when the timer does something stupid,
6183 like reinvoke itself with the same or smaller time-out.
6186 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6188 * window.c (Fsplit_window_internal): Handle only Qt value of
6189 Vwindow_combination_limit separately.
6190 (Qtemp_buffer_resize): New symbol.
6191 (Vwindow_combination_limit): New default value.
6194 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6196 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6197 the new overlay string. (Bug#10159)
6199 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6201 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6202 or that fprintf is async-signal-safe. POSIX doesn't require
6205 2012-09-22 Chong Yidong <cyd@gnu.org>
6207 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6210 2012-09-22 Kenichi Handa <handa@gnu.org>
6212 * composite.c (composition_reseat_it): Handle the case that a
6213 grapheme cluster is not covered by a single font (Bug#12352).
6215 2012-09-21 Chong Yidong <cyd@gnu.org>
6217 * image.c (define_image_type): Avoid adding duplicate types to
6218 image_types (Bug#12463). Suggested by Jörg Walter.
6220 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6222 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6223 (print_load_command_name): Add case LC_DATA_IN_CODE.
6224 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6226 2012-09-21 Glenn Morris <rgm@gnu.org>
6228 * eval.c (Frun_hook_with_args_until_success)
6229 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6231 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6233 * fileio.c (Ffile_selinux_context): Only call freecon when
6234 lgetfilecon succeeded.
6235 (Fset_file_selinux_context): Likewise. (Bug#12444)
6237 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6239 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6240 reordering, locate the cursor by calling set_cursor_from_row; if
6241 that fails, clear the desired glyph matrix before returning a
6242 failure indication to the caller. Fixes leaving garbled display
6243 when fast scrolling with a down-key. (Bug#12403)
6244 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6245 scrolling through multibyte text.
6247 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6249 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6250 calling mark_vectorlike since that's the one that marks the window.
6251 (mark_discard_killed_buffers): Mark the final cdr.
6252 * window.h (struct window): Move prev/next_buffers to the
6253 non-standard fields.
6254 * window.c (make_window): Initialize prev/next_buffers manually.
6256 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6258 Omit unused arg EXPECTED from socket hooks.
6259 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6260 * nsterm.m (ns_term_init):
6261 * termhooks.h (struct terminal.read_socket_hook):
6262 * w32inevt.c (w32_console_read_socket):
6263 * w32term.c (w32_read_socket):
6264 * xterm.c (XTread_socket):
6265 Omit unused arg EXPECTED. All callers changed.
6266 (store_user_signal_events): Return void, not int, since callers no
6267 longer care about the return value. All uses changed.
6269 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6271 * w32gui.h (XParseGeometry): Do not declare.
6273 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6275 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6276 Ignore 'expected'. See Eli Zaretskii in
6277 <http://bugs.gnu.org/12471#8> (last line).
6279 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6280 (XParseGeometry): Now static. Substitute extremal values for
6281 values that are out of range.
6283 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6285 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6287 * nsfns.m (XParseGeometry): Remove.
6288 (Fx_create_frame): Call x_set_offset to correctly interpret
6289 top_pos in geometry.
6291 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6292 (Fx_parse_geometry): If there is a space in string, call
6293 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6295 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6297 * search.c (scan_buffer): Use character positions in calls to
6298 region_cache_forward and region_cache_backward, not byte
6299 positions. (Bug#12196)
6301 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6302 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6304 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6305 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6306 emacs_blocked_malloc, now deleted.
6308 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6310 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6311 The workaround was for improving performance on Solaris 2.4, but
6312 is getting in the way now. Emacs will still work if someone is
6313 still running Solaris 2.4 in a museum somewhere; Sun dropped
6314 support for Solaris 2.4 in 2003.
6315 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6316 * process.c (create_process) [HAVE_WORKING_VFORK]:
6317 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6318 since Emacs no longer uses vfork on that platform.
6320 2012-09-17 Glenn Morris <rgm@gnu.org>
6322 * emacs.c: Use COPYRIGHT.
6324 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6326 Remove configure's --without-sync-input option (Bug#12450).
6327 When auditing signal-handling in preparation for cleaning it up,
6328 I found that SYNC_INPUT has race conditions and would be a real
6329 pain to fix. Since it's an undocumented and deprecated
6330 configure-time option, now seems like a good time to remove it.
6331 Also see <http://bugs.gnu.org/11080#16>.
6332 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6333 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6334 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6335 (malloc_hysteresis):
6336 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6337 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6338 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6339 (dont_register_blocks, bytes_used_when_reconsidered)
6340 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6341 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6342 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6343 Remove. All uses removed.
6344 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6345 implementation, one that depends on whether the new macro
6346 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6348 * atimer.c (run_timers, handle_alarm_signal):
6349 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6350 (handle_async_input, process_pending_signals)
6351 (handle_input_available_signal, init_keyboard):
6352 * nsterm.m (ns_read_socket):
6353 * process.c (wait_reading_process_output):
6354 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6355 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6357 * xterm.c (XTread_socket):
6359 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6360 * eval.c (handling_signal): Remove. All uses removed.
6361 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6362 All uses replaced with the SYNC_INPUT version.
6363 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6365 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6368 * font.c (Ffont_shape_gstring): Remove unused local.
6370 2012-09-16 Glenn Morris <rgm@gnu.org>
6372 * Makefile.in (clean): No longer run nextstep's clean.
6374 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6376 (ns-app): Move here from ns.mk, and simplify.
6377 (clean): Simplify nextstep entry.
6378 * ns.mk: Remove file.
6380 2012-09-17 Kenichi Handa <handa@gnu.org>
6382 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6383 not covert the last few charactes.
6385 2012-09-16 Kenichi Handa <handa@gnu.org>
6387 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6388 here, but just check the validity of glyphs in the glyph-string.
6390 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6392 * window.c (Fwindow_parameter, Fset_window_parameter):
6393 Accept any window as argument (Bug#12452).
6395 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6397 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6398 to ns_term_init to avoid memory leak.
6400 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6401 explicit retain/release.
6402 (ns_term_init): Only allow one display. Initialize outerpool and
6405 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6407 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6408 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6409 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6410 the Microsoft problem in a different way, by altering ../nt/config.nt.
6412 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6427 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6428 by lisp.h. This completes removal of setjmp.h inclusion
6429 erroneously announced in the previous commit. (Bug#12446)
6431 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6434 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6435 not defined as a macro. The latter happens on MS-Windows.
6438 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6440 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6441 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6442 Some instances of '#include <setjmp.h>' removed, if the
6443 only reason for the instance was because "lisp.h" was included.
6444 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6445 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6446 and _longjmp with the new symbols. Emacs already uses _setjmp if
6447 available, so this change affects only POSIXish hosts that have
6448 sigsetjmp but not _setjmp, such as some versions of Solaris and
6449 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6450 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6451 (png_load_body) [HAVE_PNG]:
6452 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6453 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6454 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6455 since PNG requires jmp_buf. This is the only exception to the
6456 general rule that we now use sys_setjmp and sys_longjmp.
6457 This exception is OK since this code does not change the signal
6458 mask or longjmp out of a signal handler.
6460 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6462 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6463 Include "syssignal.h", for 'main_thread'.
6465 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6467 Avoid out-of-range marker position (Bug#12426).
6468 * insdel.c (replace_range, replace_range_2):
6469 Adjust markers before overlays, as suggested by comments.
6470 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6471 Remove redundant check before calling offset_intervals.
6473 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6475 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6476 current buffer (Bug#12387).
6478 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6480 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6482 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6484 Use a more backwards-compatible timer format (Bug#12430).
6485 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6486 vector element, not from the 4th, since PSECS is now at the end.
6487 (Fcurrent_idle_time): Doc fix.
6489 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6491 Function to mark objects and remove killed buffers at once.
6492 * alloc.c (discard_killed_buffers): Rename to ...
6493 (mark_discard_killed buffers) ... new name. Add marking
6494 of remaining objects. Fix comment. Adjust users.
6495 (mark_object): Do not touch frame buffer lists here.
6496 * frame.c (delete_frame): Reset frame buffer lists here.
6498 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6500 Better workaround for GNOME bug when --enable-gcc-warnings.
6501 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6502 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6503 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6505 Simplify SIGIO usage (Bug#12408).
6506 The code that dealt with SIGIO was crufty and confusing, e.g., it
6507 played tricks like "#undef SIGIO" but these tricks were not used
6508 consistently. Simplify mostly by not #undeffing standard symbols,
6509 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6510 or not as we please) rather than "defined SIGIO" (standard symbol
6511 that we probably shouldn't #undef).
6512 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6513 Modules that need it can include it.
6514 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6515 * dispextern.h (ignore_sigio): New decl.
6516 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6517 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6518 * emacs.c (shut_down_emacs):
6519 * keyboard.c (kbd_buffer_store_event_hold):
6520 Use ignore_sigio rather than invoking 'signal' directly.
6521 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6523 (FIONREAD, SIGIO): Do not #undef.
6524 (tty_read_avail_input): Use #error rather than a syntax error.
6525 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6526 for I_PIPE, used by SETUP_SLAVE_PTY.
6527 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6528 * sysdep.c (croak): Remove; no longer needed. This bit of
6529 temporary code, with Fred N. Fish's comment that it's temporary,
6530 has been in Emacs since at least 1992!
6531 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6532 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6533 * syssignal.h (croak): Remove decl.
6534 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6535 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6536 now that we're termios-only.
6537 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6538 * term.c (dissociate_if_controlling_tty): Use #error rather than
6541 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6542 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6543 to work around GNOME bug 683906.
6544 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6545 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6546 This works around GCC bug 54561.
6548 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6550 More fixes for 'volatile' and setjmp/longjmp.
6551 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6552 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6553 (png_load_body) [HAVE_PNG]:
6554 (jpeg_load_body) [HAVE_JPEG]:
6555 New function, with most of the old parent function's body.
6556 (png_load) [HAVE_PNG]:
6557 (jpeg_load) [HAVE_JPEG]:
6558 Invoke the new function, to avoid longjmp munging our locals.
6559 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6560 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6561 longjmp is passed 2, as the C standard doesn't guarantee this.
6562 Instead, store the failure code into mgr->failure_code.
6564 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6566 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6567 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6568 (syms_of_keyboard): Remove support for unread-command-char.
6570 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6572 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6573 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6574 violation. (Bug#12426)
6576 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6578 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6580 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6582 * eval.c: Add `inhibit-debugger'.
6583 (Qinhibit_debugger): New symbol.
6584 (call_debugger): Bind it instead of Qdebug_on_error.
6585 (maybe_call_debugger): Test Vinhibit_debugger.
6586 (syms_of_eval): Define inhibit-debugger.
6587 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6588 (syms_of_xdisp): Remove inhibit-debug-on-message.
6590 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6592 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6593 If a nonvolatile local variable is written before a _longjmp to
6594 the frame containing the variable, and is read after the _longjmp,
6595 the value read is indeterminate. Some local variables of type
6596 'struct handler' and 'struct catchtag' are used in this way, so
6597 mark each of their slots as volatile if the slot can be set before
6598 _longjmp and read afterwards.
6599 * lisp.h (struct handler): var and chosen_clause are now volatile.
6600 (struct catchtag): val, next, and pdlcount are now volatile.
6602 * bidi.c (bidi_push_it, bidi_pop_it):
6603 * fns.c (copy_hash_table):
6604 * image.c (define_image_type):
6605 * keyboard.c (kbd_buffer_store_event_hold):
6606 * process.c (Fprocess_send_eof):
6607 * xfaces.c (x_create_gc) [HAVE_NS]:
6608 * xgselect.c (xg_select):
6609 Prefer assignment to memcpy when either will do.
6611 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6612 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6613 time an item is removed. No need to mark this function 'inline';
6614 the compiler knows better than we do.
6616 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6618 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6619 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6620 to change_frame_size (Bug#12388).
6621 (windowDidResize:): Pass YES to updateFrameSize.
6623 * nsterm.h: Add delay parameter to updateFrameSize.
6625 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6627 Discard killed buffers from deleted window and frame objects.
6628 This reduces an amount of references to killed buffers and
6629 helps GC to reclaim them faster.
6630 * alloc.c (discard_killed_buffers): New function.
6631 (mark_object): Use it for deleted windows and frames.
6632 (mark_object): If symbol's value is set up for a killed buffer
6633 or deleted frame, restore its global binding.
6634 * data.c (swap_in_global_binding): Add GC notice.
6635 (swap_in_symval_forwarding): Use convenient set_blv_where.
6636 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6637 * window.h: ... to here.
6639 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6641 Convenient macro to check whether the buffer is live.
6642 * buffer.h (BUFFER_LIVE_P): New macro.
6643 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6644 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6646 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6648 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6649 composition cases (Bug#12364).
6651 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6652 overhang of succeeding glyphs overlapping box cursor.
6654 * w32term.c (x_draw_glyph_string): Likewise.
6656 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6658 Simplify, document, and port floating-point (Bug#12381).
6659 The porting part of this patch fixes bugs on non-IEEE platforms
6660 with frexp, ldexp, logb.
6661 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6663 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6664 support, by removing commented-out code and briefly listing the
6665 C89 functions excluded. The commented-out stuff was confusing
6666 maintenance, e.g., we thought we needed cbrt but it was commented out.
6667 (logb): Remove decl; no longer needed.
6668 (isfinite): New macro, if not already supplied.
6669 (isnan): Don't replace any existing macro.
6670 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6671 are present on all C89 platforms.
6672 (Ffrexp): Do not special-case zero, as frexp does the right thing
6674 (Flogb): Do not use logb, as it doesn't have the desired meaning
6675 on hosts that use non-base-2 floating point. Instead, stick with
6676 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6677 frexp, to avoid getting an unspecified result.
6679 * xdisp.c (Qinhibit_debug_on_message): Now static.
6681 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6683 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6684 NSBezierPath (Bug#12131).
6686 2012-09-10 Chong Yidong <cyd@gnu.org>
6688 * fns.c (Fdelq, Fdelete): Doc fix.
6690 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6692 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6693 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6695 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6697 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6698 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6701 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6703 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6704 left fringe if the window has a left margin. This avoids leaving
6705 traces of the cursor because its leftmost pixel is not drawn over.
6707 * dispnew.c (update_window_line): When the left margin area of a
6708 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6709 that screen line. (Bug#12277)
6711 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6713 Assume C89 or later for math functions (Bug#12381).
6714 This simplifies the code, and makes it a bit smaller and faster,
6715 and (most important) makes it easier to clean up signal handling
6716 since we can stop worring about floating-point exceptions in
6717 library code. That was a problem before C89, but the problem
6718 went away many years ago on all practical Emacs targets.
6719 * data.c, image.c, lread.c, print.c:
6720 Don't include <math.h>; no longer needed.
6721 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6722 might be autoconfigured, as that never happens.
6724 * doprnt.c (DBL_MAX_10_EXP):
6725 * print.c (DBL_DIG):
6726 Remove. C89 or later always defines these.
6727 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6728 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6729 (arith_error, domain_error, domain_error2):
6730 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6731 no longer needed -- we simply return what C returns. All uses removed.
6732 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6734 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6735 Remove. All uses expanded, as these macros are no longer used
6736 more than once and are now more trouble than they're worth.
6737 (Ftan): Use tan, not sin / cos.
6738 (Flogb): Assume C89 frexp.
6739 (fmod_float): Assume C89 fmod.
6740 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6741 (init_floatfns): Remove. All uses removed.
6743 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6745 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6746 compositeToPoint for OSX < 10.6 (Bug#12390).
6748 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6750 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6751 This produces more-accurate results.
6753 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6755 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6756 changes (Bug#12088).
6758 2012-09-08 Chong Yidong <cyd@gnu.org>
6760 * syntax.c (Fstring_to_syntax): Doc fix.
6762 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6764 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6765 in the internal border.
6766 (x_set_window_size): Remove static variables and their usage.
6767 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6768 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6769 Remove fringe/internal border adjustment (Bug#11052).
6770 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6771 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6772 (ns_fix_rect_ibw): Remove.
6773 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6774 (ns_dumpglyphs_box_or_relief): Ditto.
6775 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6777 (ns_dumpglyphs_image): Ditto.
6778 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6780 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6781 their usage. Add fringe_extended_p and its use as in other terms.
6782 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6783 scroll bar was removed.
6784 (updateFrameSize): New function.
6785 (windowDidResize): Move code to updateFrameSize and call it.
6787 * nsterm.h (EmacsView): Add updateFrameSize.
6789 2012-09-07 Chong Yidong <cyd@gnu.org>
6791 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6793 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6795 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6797 More signal-handler cleanup (Bug#12327).
6798 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6799 Problem introduced when merging patches. Noted by Eli Zaretskii in
6800 <http://bugs.gnu.org/12327#67>.
6801 * floatfns.c: Comment fix.
6802 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6803 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6804 and anyway the declaration is harmless even if SIGDANGER is not defined.
6805 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6806 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6807 source files not surprisingly expected syssignal.h to define, or
6808 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6809 Include <sys/ioctl.h>, for FIONREAD.
6810 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6811 This eliminates a problem whereby other files mysteriously had
6812 to include "syssignal.h" before including "systty.h" if they
6813 wanted to use "#ifdef SIGIO".
6815 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6817 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6819 * w32.c (sigemptyset): Empty the set.
6820 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6822 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6824 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6826 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6827 (mark_object): Likewise for frame objects.
6829 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6831 * syssignal.h (handle_on_main_thread): Always declare,
6832 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6833 This ports to platforms without HAVE_PTHREAD.
6835 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6837 Signal-handler cleanup (Bug#12327).
6838 Emacs's signal handlers were written in the old 4.2BSD style with
6839 sigblock and sigmask and so forth, and this led to some
6840 inefficiencies and confusion. Rewrite these to use
6841 pthread_sigmask etc. without copying signal sets around. Also,
6842 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6843 'signal', and instead use functions that do not attempt to take
6844 over the system name space. This patch causes Emacs's text
6845 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6846 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6847 Do not include <signal.h> or "syssignal.h", as these
6848 modules do not use signals.
6849 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6850 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6851 Do not include <signal.h>, as "syssignal.h" does that for us now.
6852 * atimer.c (sigmask_atimers): New function.
6853 (block_atimers, unblock_atimers): New functions,
6854 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6856 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6857 no longer needed here.
6858 * emacs.c (main): Inspect existing signal handler with sigaction,
6859 so that there's no need to block and unblock SIGHUP.
6860 * sysdep.c (struct save_signal): New member 'action', replacing
6861 old member 'handler'.
6862 (save_signal_handlers, restore_signal_handlers):
6863 Use sigaction instead of 'signal' to save and restore.
6864 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6865 New function. All users of 'signal' modified to use set_sighandler
6866 if they're writeonly, and to use sys_signal if they're read+write.
6867 (emacs_sigaction_init, forwarded_signal): New functions.
6868 (sys_signal): Remove. All uses replaced by calls to sigaction
6869 and emacs_sigaction_init, or by direct calls to 'signal'.
6870 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6871 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6872 all uses replaced by pthread_sigmask etc. calls.
6873 * syssignal.h: Include <signal.h>.
6874 (emacs_sigaction_init, forwarded_signal): New decls.
6875 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6876 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6877 (sigmask, sys_sigmask): Remove; no longer needed.
6878 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6879 (sigblock, sigunblock, sigfree):
6880 (sigsetmask) [!defined sigsetmask]:
6881 Remove. All uses replaced by pthread_sigmask.
6882 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6883 no longer need to be replaced, and its typical old uses
6884 are now done via emacs_sigaction_init and sigaction.
6885 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6886 (sys_sigdel): Remove; unused.
6887 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6889 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6891 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6892 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6894 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6896 Explicitly mark buffer_defaults and buffer_local_symbols.
6897 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6898 mark_local_symbols here.
6899 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6900 since special buffers aren't marked here any more.
6901 (allocate_buffer): Chain new buffer with all_buffers here...
6902 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6904 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6905 (syms_of_buffer): Remove staticpro of the above.

6909 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6911 Use bool for booleans in font-related modules.
6912 * font.c (font_intern_prop, font_style_to_value)
6913 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6914 (generate_otf_features, font_check_otf_features, font_check_otf)
6915 (font_match_p, font_list_entities, font_at):
6916 * fontset.c (fontset_id_valid_p, reorder_font_vector
6917 (fontset_find_font, Fset_fontset_font)
6918 (face_suitable_for_char_p) [0]:
6919 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6920 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6921 (m17n_flt_initialized, ftfont_shape_by_flt):
6922 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6923 * nsfont.m (nsfont_draw):
6924 * w32font.c (w32font_draw):
6925 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6926 Use bool for booleans.
6927 * font.h: Adjust to above API changes.
6928 (struct font, struct font_driver, struct font_driver_list):
6929 Use bool for booleans.
6930 (struct font): Remove useless member encoding_type.
6932 * fontset.c, xftfont.c: Omit unnecessary static decls.
6934 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6936 * alloc.c (mark_object): Revert window marking code
6937 since it's unsafe for the Fset_window_configuration.
6939 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6941 Fix race conditions with signal handlers and errno (Bug#12327).
6942 Be more systematic about preserving errno whenever a signal
6943 handler returns, even if it's not in the main thread. Do this by
6944 renaming signal handlers to distinguish between signal delivery
6945 and signal handling. All uses changed.
6946 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6947 * data.c (deliver_arith_signal): Rename from arith_error.
6948 * dispnew.c (deliver_window_change_signal): Rename from
6949 window_change_signal.
6950 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6951 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6952 * keyboard.c (deliver_input_available_signal): Rename from
6953 input_available_signal.
6954 (deliver_user_signal): Rename from handle_user_signal.
6955 (deliver_interrupt_signal): Rename from interrupt_signal.
6956 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6957 (deliver_child_signal): Rename from sigchld_handler.
6958 * atimer.c (handle_alarm_signal):
6959 * data.c (handle_arith_signal):
6960 * dispnew.c (handle_window_change_signal):
6961 * emacs.c (handle_fatal_signal, handle_danger_signal):
6962 * keyboard.c (handle_input_available_signal):
6963 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6964 * process.c (handle_pipe_signal, handle_child_signal):
6965 New functions, with the actual signal-handling code taken from the
6966 original respective signal handlers, sans the sporadic attempts to
6967 preserve errno, since that's now done by handle_on_main_thread.
6968 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6969 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6970 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6972 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6973 Move initialization of main_thread to sysdep.c's init_signals.
6974 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6975 our usage, and simplifies the mainline code.
6976 (record_child_status_change): New static function, as a helper
6977 for handle_child_signal, and with most of the old child handler's
6979 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6980 (handle_child_signal): Use the above.
6981 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6982 Moved here from emacs.c.
6983 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6984 code moved here from emacs.c's main function.
6985 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6986 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6987 This lets callers save and restore errno properly.
6989 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6991 Remove redundant or unused things here and there.
6992 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6993 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6994 * editfns.c (Fcompare_buffer_substrings): Likewise.
6995 * frame.h (struct terminal, struct font_driver_list):
6996 Remove redundant declarations.
6997 * window.h (Qleft, Qright): Likewise.
6999 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7001 Do not mark objects from deleted buffers, windows and frames.
7002 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7003 (mark_object): Likewise for windows and frames.
7005 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7007 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7008 buffer_defaults and buffer_local_symbols as valid objects.
7009 Return special value to denote them.
7011 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7013 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7014 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7015 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7016 (file_name_absolute_p, Fsubstitute_in_file_name):
7017 (check_executable, check_writable, Ffile_accessible_directory_p)
7018 (Fset_file_selinux_context, Fdefault_file_modes)
7019 (Finsert_file_contents, choose_write_coding_system)
7020 (Fwrite_region, build_annotations, a_write, e_write)
7022 * filelock.c (boot_time_initialized, get_boot_time)
7023 (get_boot_time_1, lock_file_1, within_one_second):
7024 * floatfns.c (in_float):
7025 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7026 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7027 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7028 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7029 * window.c (compare_window_configurations):
7030 Use bool for booleans.
7031 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7032 (Fdefault_file_modes): Now mode_t, not int, for modes.
7033 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7034 (internal_delete_file): Now returns void, not a (boolean) int,
7035 since nobody was looking at the return value.
7036 * lisp.h, window.h: Adjust to above API changes.
7038 * xdisp.c (set_message): Simplify and reindent last change.
7040 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7042 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7044 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7046 * eval.c (call_debugger): Make the function non-static so that we
7047 can call it from set_message.
7049 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7050 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7052 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7054 Give more-useful info on a fatal error (Bug#12328).
7055 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7056 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7057 of doing the work ourselves.
7058 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7059 do most of the work.
7060 (fatal_error_backtrace): New function, taken from the guts
7061 of the old fatal_error_signal, but with a new option to output
7063 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7064 info about the signal than just its number.
7065 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7066 * sysdep.c: Include <execinfo.h>
7067 (emacs_backtrace): New function, taken partly from the previous
7068 code of the 'die' function.
7069 (emacs_abort): Call fatal_error_backtrace rather than abort.
7071 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7073 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7074 eager (load-time) macro-expansion.
7075 * lisp.mk (lisp): Add macroexp.
7077 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7079 Simplify redefinition of 'abort' (Bug#12316).
7080 Do not try to redefine the 'abort' function. Instead, redo
7081 the code so that it calls 'emacs_abort' rather than 'abort'.
7082 This removes the need for the NO_ABORT configure-time macro
7083 and makes it easier to change the abort code to do a backtrace.
7084 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7085 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7086 Remove; sysdep.c's emacs_abort now takes its place.
7087 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7088 'abort' changed to use 'emacs_abort'.
7089 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7090 (abort) [!defined abort]: Rename to ...
7091 (emacs_abort): ... new name.
7092 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7093 the place of the old 'abort' in emacs.c.
7094 * w32.c, w32fns.c (abort): Do not #undef.
7095 * w32.c (emacs_abort): Rename from w32_abort.
7097 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7099 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7100 offsets[j].dv, since the y axis of the screen coordinates points
7101 down, while the y axis of the font definition coordinates points
7102 up. This fixes display of Arabic diacritics such as KASRA and
7103 KASRATAN. (Bug#11860)
7105 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7107 Be more systematic about _setjmp vs setjmp.
7108 * alloc.c (test_setjmp, mark_stack):
7109 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7110 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7111 (png_load, my_error_exit, jpeg_load):
7112 * process.c (send_process_trap, send_process):
7113 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7114 The underscored versions are up to 30x faster on some hosts.
7115 Formerly, the code used setjmp+longjmp sometimes and
7116 _setjmp+_longjmp at other times, with no particular reason to
7117 prefer setjmp+longjmp.
7119 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7121 Fix minor problem found by static checking.
7122 * buffer.c (Fdelete_all_overlays): Return nil.
7124 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7126 * buffer.c (Fdelete_all_overlays): New function.
7128 2012-09-03 Chong Yidong <cyd@gnu.org>
7130 * gtkutil.c: Add extern decl for Qxft.
7132 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
7134 * emacs.c, eval.c: Use bool for boolean.
7135 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
7136 (malloc_using_checking) [DOUG_LEA_MALLOC]:
7137 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
7138 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
7139 (main, decode_env_path, Fdaemon_initialized):
7140 * eval.c (call_debugger, Finteractive_p, interactive_p):
7141 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
7142 (maybe_call_debugger, Fbacktrace):
7143 * process.c (read_process_output, exec_sentinel):
7144 Use bool for booleans.
7145 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
7146 All callers changed.
7147 * eval.c (interactive_p): Omit always-true boolean argument
7148 EXCLUDE_SUBRS_P. All callers changed.
7149 * dispextern.h, lisp.h: Reflect above API changes.
7150 * firstfile.c (dummy): Use the address of 'main', whose signature
7151 won't change, instead of the address of 'initialize', whose
7152 signature just changed from int to bool.
7153 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7154 * msdos.c (fatal_error_in_progress): ... from here.
7155 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7157 (redisplay_internal, unwind_redisplay): Simply clear
7158 REDISPLAYING_P when unwinding, instead of saving its previous,
7159 always-false value and then restoring it.
7161 Clean up some extern decls.
7162 Mostly, this hoists extern decls out of .c files and into .h files.
7163 That way, we're more likely to catch errors if the interfaces change.
7164 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7165 declare xg_mark_data.
7166 * dispextern.h (x_frame_parm_handlers):
7168 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
7169 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
7170 (Qultra_bold, Qoblique, Qitalic):
7171 Move extern decl here from .c file.
7172 * alloc.c (xg_mark_data) [USE_GTK]:
7174 * eval.c (Qlexical_binding):
7175 * fns.c (time) [!HAVE_UNISTD_H]:

7181 * process.c (QCfamily, QCfilter):
7182 * widget.c (free_frame_faces):
7183 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
7184 * xfont.c (x_clear_errors):
7185 * xterm.c (x_frame_parm_handlers):
7186 Remove now-redundant extern decls.
7187 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7188 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7190 * xfaces.c: Remove unnecessary static decls.
7191 * xterm.c (updating_frame): Remove decl of nonexistent object.
7193 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7194 when building globals.h, as the objects that are not built on
7195 this host are not needed to compile C files on this host.
7197 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
7199 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
7201 * frame.h: Add missing prototype for x_wm_set_size_hint.
7203 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

7207 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
7208 (Fsubstitute_command_keys):

7210 (save_excursion_save, save_excursion_restore)
7211 (disassemble_lisp_time, decode_time_components, emacs_nmemftime)

7213 (make_buffer_string, make_buffer_string_both)
7214 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

7232 2012-09-02 Chong Yidong <cyd@gnu.org>
7234 * keymap.c (push_key_description): Print M-TAB as C-M-i
7237 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
7239 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
7240 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
7241 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

7245 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
7247 2012-09-01 Eli Zaretskii <eliz@gnu.org>
7249 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7250 more than one grapheme cluster passed to the shaper: compute the
7251 offset adjustment values separately for each cluster. (Bug#11860)
7253 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7254 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7255 about implicit conversions from integer to pointer.
7257 2012-09-01 Daniel Colascione <dancol@dancol.org>
7259 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7260 system used too early.
7262 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
7264 Better seed support for (random).
7265 * emacs.c (main): Call init_random.
7266 * fns.c (Frandom): Set the seed from a string argument, if given.
7267 Remove long-obsolete Gentzel cruft.
7268 * lisp.h, sysdep.c (seed_random): Now takes address and size, not long.
7269 (init_random): New function.
7271 2012-09-01 Daniel Colascione <dancol@dancol.org>
7273 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
7274 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
7275 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
7276 x_wm_set_size_hint, x_query_colors, x_real_positions,
7277 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
7278 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,

7369 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
7370 does not become zero (Bug#12234).

7400 (timeout_handler:): Set timer_fired to YES.
7401 (runDialogAt:): Set timer_fired to NO.
7402 Handle click on close button as quit.
7404 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7405 Add window_closed and button_values. Add void as return value for
7406 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7407 Add process_dialog as new member.
7409 2012-08-28 Eli Zaretskii <eliz@gnu.org>
7411 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

7547 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
7548 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
7549 not a boolean 'int', since callers never look at the return value.

7552 (emacs_mule_string_char): Remove unused extern decls.
7553 (struct iso_2022_spec, struct coding_system):

7561 Fix spare memory change (Bug#12286).
7562 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7563 (valid_lisp_object_p): Likewise.
7565 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7567 * window.c (Fset_window_configuration): Record any window's old
7568 buffer if it's replaced (see Bug#8789). If the new current
7569 buffer doesn't appear in the selected window, go to its old
7572 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7574 Special MEM_TYPE_SPARE to denote reserved memory.
7575 * alloc.c (enum mem_type): New memory type.
7576 (refill_memory_reserve): Use new type for spare memory.
7577 This prevents live_cons_p and live_string_p from incorrect

7587 * window.c (Qwindow_valid_p, decode_valid_window):
7588 Now static, not extern.
7589 * data.c (Qinterval): Remove; unused.

7606 (map_sub_char_table):
7607 Use bool for boolean.

7609 always 0. All callers changed.
7610 * character.h, charset.h: Adjust to match previous changes.
7611 * character.h (char_printable_p): Remove decl of nonexistent function.
7612 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7613 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7614 are all boolean, so make them single-bit bitfields.
7616 * lisp.h (ASET): Remove attempt to detect side effects.
7617 It was meant to be temporary and it often doesn't work,
7618 because when IDX has side effects the behavior of IDX==IDX
7619 is undefined. See Stefan Monnier in
7620 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7622 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7624 * lisp.h (functionp): New function (extracted from Ffunctionp).
7625 (FUNCTIONP): Use it.
7626 * eval.c (Ffunctionp): Use it.
7628 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7630 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7631 as that's faster and simpler than static storage. Don't bother
7632 with the g_main_context_query overhead if g_main_context_pending
7633 says no events are pending.
7634 (gfds, gfds_size): Remove these static vars.
7635 (xgselect_initialize): Remove; no longer needed.
7636 All uses and decls removed.
7638 * emacs.c (fatal_error_signal_hook): Remove.
7639 All uses removed. This leftover from old code was always 0.

7666 Use bool for booleans, instead of int.
7667 * lisp.h, process.h: Adjust prototypes to match above changes.
7668 * callint.c (Fcall_interactively): Don't assume the mark's
7669 offset fits in 'int'.

7681 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7682 Use bool for booleans, instead of int.
7683 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7684 since the 1-or-0 return value is always ignored anyway.
7685 (mmap_initialized_p):
7686 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7687 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7689 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7691 * bidi.c: Use bool for boolean.
7692 This is a bit more readable, and makes the text segment of bidi.o
7693 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7694 Presumably it's faster too.

7728 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7730 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7731 Otherwise, the compiler complains about (A?B:C) where B is void
7732 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7733 (fontset_add): Return void, for FONTSET_ADD.
7735 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>

7739 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7740 (dont_register_blocks) [GC_MALLOC_CHECK]:
7741 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7742 (check_string_bytes, make_specified_string, memory_full)
7743 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7744 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7745 (mark_stack, valid_pointer_p, make_pure_string)
7746 (Fgarbage_collect, survives_gc_p, gc_sweep):
7747 Use bool for booleans, instead of int.
7748 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7749 Remove unused local.
7750 * alloc.c (PURE_POINTER_P):
7751 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7752 * editfns.c (Fformat):
7753 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7755 * fns.c (sweep_weak_table):
7756 * lisp.h (suppress_checking, push_message, survives_gc_p)
7757 (make_pure_string, gc_in_progress, abort_on_gc):
7758 * lread.c (readchar, read1):
7759 * print.c (Fprin1_to_string):
7760 * xdisp.c (push_message):
7761 Use bool for booleans affected directly or indirectly by
7764 Make recently-introduced setters macros.
7765 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7766 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7767 (set_fontset_default, set_fontset_fallback): Rename from their
7768 upper-case counterparts, and make them functions rather than macros.
7769 This is more consistent with the other recently-introduced setters.
7770 These don't need to be inline, since they're local.
7772 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7774 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in

7777 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7779 * lisp.h (vcopy): Use memcpy rather than our own loop.
7780 This fixes a performance regression introduced by the recent
7781 addition of vcopy. This means 'vcopy' will need to be modified
7782 for a copying collector, but that's OK. Also, tighten the
7783 checking in the assertion.
7785 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7787 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7788 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7789 non-base glyph for the width of the base character, according to
7790 what x_draw_composite_glyph_string_foreground expects.
7791 Generate WADJUST value according to composition_gstring_width's
7792 expectations, to produce correct width of the composed character.
7793 Reverse the sign of the DU offset produced by ScriptPlace.
7795 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7797 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.

7818 buffer to the specified position.
7820 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>

7823 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7824 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7825 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7828 2012-08-20 Glenn Morris <rgm@gnu.org>
7830 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7831 Don't assume that `ln -f' works.
7833 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7835 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7836 and later about non-assignments with no effect. See discussion at
7837 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7840 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7842 Inline setter functions for Lisp_Objects slots of struct specbinding.
7843 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7846 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7848 * window.c (select_window): Always make selected window's buffer
7851 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>

7854 * category.h (CATEGORY_DOCSTRING): Use AREF.
7855 (SET_CATEGORY_DOCSTRING): Use ASET.
7856 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7858 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7860 Inline setter functions for hash table members.
7861 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7862 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7863 (set_hash_key_and_value, set_hash_index, set_hash_next)
7864 (set_hash_hash): New functions.
7865 * charset.c, fns.c: Adjust users.
7867 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7869 Inline getter and setter functions for per-buffer values.

7873 * buffer.c, data.c: Adjust users.
7875 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7877 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7879 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7881 Rely on <config.h> + <unistd.h> to declare 'environ',
7882 as gnulib does this if the system doesn't.
7883 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7884 Remove declaration. MS-Windows declares it on stdlib.h which is
7885 included by conf_post.h.
7886 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7887 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7888 * vm-limit.c: Include <unistd.h>, for 'environ'.
7890 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7891 (start_of_data): Remove decl; mem-limits.h provides it.
7893 * xdisp.c (handle_invisible_prop): Make it a bit faster
7894 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7896 2012-08-19 Chong Yidong <cyd@gnu.org>
7898 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7901 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>

7906 * data.c (set_internal): Don't use set_blv_found.
7907 (Fkill_local_variable): Likewise.
7909 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7911 * nsfont.m (ns_ascii_average_width): Ensure the string
7912 ascii_printable is initialized with a null-terminated character
7913 array. Otherwise, it can contain undesired extra characters.
7915 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7917 port new setting code to Sun C 5.8 2005/10/13
7918 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7919 Return void, not Lisp_Object. Otherwise, the compiler
7920 complains about (A?B:C) where B is void and C is Lisp_Object
7921 when compiling CHAR_TABLE_SET, due to the recent change to
7922 the API of sub_char_table_set_contents.
7924 2012-08-18 Chong Yidong <cyd@gnu.org>
7926 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE

8083 'parent' for two different things.

8096 font spec, make the font's attributes take precedence over
8097 directly-specified attributes.
8098 (merge_face_ref): Recognize :font.
8100 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

8147 Use C-locale tests instead of locale-specific tests for character
8148 types, since we want the ASCII interpretation here, not the
8149 interpretation suitable for whatever happens to be the current locale.

8754 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
8755 * w32.c (init_environment): Change the default values of many
8756 environment variables in dflt_envvars[] to NULL, to avoid pushing
8757 them into environment when they were not already defined.
8758 Remove the code that deletes site-lisp subdirectories from the default
8759 value of EMACSLOADPATH, as it is no longer needed.
8760 (check_windows_init_file): Now external, not static.
8761 Use Vload_path as is, without adding anything, as this function is now
8762 called when Vload_path is already set up.
8764 * w32.h (check_windows_init_file): Add prototype.
8766 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

8772 any, in the DEFALT argument into the root of the Emacs build or
8773 installation tree, as appropriate.
8775 * callproc.c (init_callproc_1): Call decode_env_path instead of
8776 doing its equivalent by hand.
8777 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
8778 the code that sets Vexec_path run on MS-Windows.
8780 * lread.c (init_lread): Add comments to #ifdef's.
8782 * msdos.c (dos_set_window_size, IT_update_begin)

8790 Now constants, not macros.
8792 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
8794 Remove unnecessary casts involving pointers.
8795 These casts are no longer needed now that we assume C89 or later,
8796 since they involve casting to or from void *.
8797 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
8798 (make_pure_float, make_pure_vector):
8799 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

8808 (x_get_window_property, x_get_window_property_as_lisp_data):
8809 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8810 Remove unnecessary pointer casts.
8811 * alloc.c (record_xmalloc): New function.
8812 * lisp.h (record_xmalloc): New decl.
8813 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8814 more like a function. This is because the pointer cast is not
8815 needed. All uses changed.
8816 * print.c (print_string, print_error_message): Avoid length recalc.
8818 Improve fix for macroexp crash with debugging (Bug#12118).
8819 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8820 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8821 not supposed to be invoked from the garbage collector.
8822 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
8823 (gc_aset): New function, which is like ASET but can be
8824 used in the garbage collector.
8825 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

8837 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
8838 (map_w32_filename): Improve commentary. Simplify switch.
8839 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
8840 headers (most versions of MinGW w32api don't).
8841 (get_security_info, create_symbolic_link)
8842 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
8844 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
8845 in the argument file name.

8848 (sys_rename): Diagnose renaming of a symlink when the user doesn't
8849 have the required privileges.
8850 (get_file_security_desc_by_name): Rename from
8851 get_file_security_desc.

8853 with addition of handling of symlinks and support for 'lstat'.
8854 If possible, get file's attributes and security information by
8855 handle, not by name. Produce S_IFLNK bit for symlinks, when
8856 called from 'lstat'.
8857 (stat, lstat): New functions, call 'stat_worker'.
8858 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8859 symlinks when the underlying filesystem supports them.
8861 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8863 Fix macroexp crash on Windows with debugging (Bug#12118).
8864 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8865 checking subscripts; problem introduced with the recent
8866 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8867 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8868 since it's used in non-static inline functions now.
8870 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8871 Don't assume buffer size fits in 'int'. Remove unused local.
8873 Use C99-style 'extern inline' if available.

8885 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
8886 * alloc.c (LISP_INLINE):

8888 * category.c (CATEGORY_INLINE):
8889 * character.c (CHARACTER_INLINE):
8890 * charset.c (CHARSET_INLINE):
8891 * composite.c (COMPOSITE_INLINE):
8892 * dispnew.c (DISPEXTERN_INLINE):
8893 * sysdep.c (SYSTIME_INLINE):
8894 Define to EXTERN_INLINE, so that the corresponding functions
8895 are compiled into code.
8896 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8897 (INLINE_HEADER_END): New macros.
8898 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8918 hard-coding the path separator.
8920 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8922 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8923 This how ASET and AREF are supposed to work, and makes
8924 it easier to think about future improvements. See
8925 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8926 * charset.h (set_charset_attr): New function.

9418 the fix for 12036 would have avoided some of the problems noted in

9430 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9431 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9432 not be usable in #if. This simplifies things.
9434 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9436 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

9443 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9444 Adjust to changes in lisp.h and emacs.c, by using

9447 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

9451 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9452 instead of gdb_array_mark_flag.
9453 (xboolvector): Get size from $->size, not $->header.size.
9454 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9455 (xreload, hook-run, hookpost-run): Remove.
9456 * emacs.c: Include <verify.h>.
9457 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9458 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9460 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9461 (gdb_USE_LSB_TAG): New enum constants.
9462 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9463 Also define these as enum constants, so they're visible to GDB.

9465 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

9470 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9471 more convenient now. All uses changed.
9472 (VALMASK) [USE_LSB_TAG]: Also define in this case.

9475 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

9480 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
9482 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,

10312 The functional style also makes code easier to read and maintain.
10313 * systime.h: Include <sys/time.h> on all hosts, not just if

10349 (menu_separator_name_p):
10350 * nsmenu.m (ns_update_menubar):
10351 Prefer memcmp to strncmp when either will do.
10352 * nsterm.m: Include <ftoastr.h>.
10354 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10355 Prefer snprintf to strncpy.
10356 * nsterm.m (ns_term_init):
10357 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10358 * nsterm.m (ns_term_init):
10359 Avoid the need for strncpy, by using build_string or
10360 make_unibyte_string directly. Use dtoastr, not snprintf.
10361 * process.c (Fmake_network_process): Diagnose service names that
10362 are too long, rather than silently truncating them or creating
10363 non-null-terminated names.

10393 Optimize pure C strings initialization.
10394 * lisp.h (make_pure_string): Fix prototype.
10395 (build_pure_c_string): New function, defined as static inline. This
10396 provides a better opportunity to optimize away calls to strlen when
10397 the function is called with compile-time constant argument.
10398 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10399 argument, adjust users accordingly. Use build_pure_c_string where
10401 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
10402 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10403 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
10405 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10407 Avoid calls to strlen in miscellaneous functions.
10408 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
10409 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
10410 * lread.c (openp): Likewise.
10412 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10414 Avoid calls to strlen in path processing functions.
10415 * fileio.c (file_name_as_directory): Add comment. Change to add
10416 srclen argument and return the length of result. Adjust users
10418 (directory_file_name): Fix comment. Change to add srclen argument,
10419 swap 1st and 2nd arguments to obey the common convention.
10420 Adjust users accordingly.
10421 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
10423 2012-07-10 Glenn Morris <rgm@gnu.org>

10426 Move PENDING_OUTPUT_COUNT definition to configure.
10428 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):

10430 * s/gnu.h (DATA_START): Move definitions to configure.
10432 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10433 We include usg5-4-common.h, which defines them both.
10435 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10436 O_RDONLY already includes it).
10438 Stop ns builds setting the EMACSLOADPATH environment variable.
10439 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10440 Now it does not set EMACSLOADPATH, just returns the load-path string.
10441 * nsterm.h: Update accordingly.
10442 * lread.c [HAVE_NS]: Include nsterm.h.
10443 (init_lread) [HAVE_NS]: Use ns_load_path.
10444 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10446 2012-07-09 Glenn Morris <rgm@gnu.org>
10448 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10449 since the included bsd-common.h does so.
10451 Stop ns builds setting the EMACSPATH environment variable.
10452 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10453 (ns_init_paths): Do not set EMACSPATH.
10454 * nsterm.h (ns_exec_path): Add it.
10455 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10458 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10460 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10462 * process.c (wait_reading_process_output): 'waitchannels' was unset
10463 when read_kbd || !NILP (wait_for_cell); fix this.
10465 Add GCC-style 'const' attribute to functions that can use it.
10466 * character.h (char_resolve_modifier_mask):
10467 * keyboard.h (make_ctrl_char):
10468 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10469 (init_character_once, next_almost_prime, init_fns, init_image)
10470 (flush_pending_output, init_sound):

10479 Minor improvements to make_formatted_string.
10480 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10481 where int is good enough, as vsprintf returns an int.
10482 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10484 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10486 Use make_formatted_string to avoid double length calculation.
10487 * lisp.h (make_formatted_string): New prototype.

10509 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10511 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10513 Move marker debugging code under MARKER_DEBUG.
10514 * marker.c (MARKER_DEBUG): Move marker debugging code under
10515 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10516 for bootstrap with --enable-checking (~3x slowdown reported
10517 by Juanma Barranquero <lekktu@gmail.com>).
10518 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10520 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10522 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10523 See <http://bugs.gnu.org/11825#29>.
10525 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10527 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10528 has no font, use the frame's font. (Bug#11813)
10529 (display_line): Add commentary about displaying truncation glyphs
10531 (produce_special_glyphs): Move here from term.c.
10533 * term.c (produce_special_glyphs): Move to xdisp.c.
10535 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10538 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10540 * xdisp.c (display_line): Avoid warning about implicit declaration
10543 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10545 * lisp.h: Remove empty conditional.
10547 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10549 * lread.c (load_path_check): Now static.
10551 Fix some minor --with-ns problems found by static checking.
10552 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10553 (x_set_font) [!HAVE_X_WINDOWS]:
10554 * image.c (xpm_load_image) [HAVE_NS]:
10555 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10556 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10557 Remove unused local.
10558 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10559 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10560 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10561 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10562 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10563 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10564 Fix pointer signedness problem.
10565 * xfaces.c (FRAME_X_FONT_TABLE):
10566 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10568 2012-07-07 Glenn Morris <rgm@gnu.org>
10570 * lread.c (load_path_check): New function, split from init_lread.
10571 (init_lread): Reorganize. Motivation:
10572 If EMACSLOADPATH is set, check/warn about that rather than the
10573 defaults, which we are not going to use. Hence we can remove
10574 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10575 Don't warn if site-lisp directories are missing.
10576 If not installed, start from a blank load-path, since
10577 PATH_LOADSEARCH refers to the eventual installation directories.
10579 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10581 Support truncation and continuation glyphs on GUI frames, when
10582 fringes are disabled. (Bug#11832)
10583 * xdisp.c (init_iterator): Get dimensions of truncation and
10584 continuation glyphs even if on GUI frames.
10585 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10586 or both, are absent.
10587 (start_display, move_it_in_display_line_to): Handle the case of a
10588 GUI frame without a fringe to display continuation or truncation
10590 (insert_left_trunc_glyphs): Support GUI frames: make sure
10591 truncation glyphs overwrite enough glyphs from the current line to
10592 have sufficient space in pixels.
10593 (display_line): Support truncation and continuation glyphs on GUI
10594 frames. If some spare pixels are left on the line after inserting
10595 the truncation glyphs, fill that space with a stretch glyph of a
10596 suitably computed width.
10598 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10599 produce_glyphs, to support GUI sessions.
10601 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10603 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10605 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10607 Do not require float-time's arg to fit in time_t (Bug#11825).
10608 This works better on hosts where time_t is unsigned, and where
10609 float-time is applied to the (negative) difference between two times.
10610 * editfns.c (decode_time_components): Last arg is now double *,
10611 not int *, and means to store all the result as a double, without
10612 worrying about whether the seconds part fits in time_t.
10613 All callers changed.
10614 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10615 All callers changed.
10616 (Ffloat_time): Do not fail merely because the specified time falls
10617 outside of time_t range.
10619 2012-07-07 Glenn Morris <rgm@gnu.org>
10621 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10622 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10623 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10625 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10627 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10628 Update dependencies.

10636 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10637 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10638 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10639 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10641 * xfont.c (compare_font_names): Redo to omit the need for casts.
10643 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10645 * xfns.c (Fx_change_window_property): Doc fix.
10646 * w32fns.c (Fx_change_window_property): Doc fix.
10648 * w32fns.c (Fx_window_property): Accept the same arguments as the
10649 X Windows version. Doc fix.
10650 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10652 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10653 Eli Zaretskii <eliz@gnu.org>
10655 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10656 Windows-specific code from nt/config.nt moved here.
10657 Obsolete settings removed.
10659 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10661 * process.c: Avoid unnecessary calls to gettime.
10662 (wait_reading_process_output): Don't get the time of day
10663 when gobbling data immediately and not waiting, as there's no need
10664 for it in that case. This removes a FIXME.
10666 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10668 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10669 is defined (Bug#11768).
10671 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10673 Fix marker debugging code.
10674 * marker.c (byte_char_debug_check): Do not perform the check
10675 if buffer is not multibyte.
10676 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10677 Call byte_char_debug_check with correct arguments.
10679 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10681 Compile marker debugging code only if ENABLE_CHECKING is defined.
10682 * marker.c (byte_char_debug_check, count_markers):
10683 Use only if ENABLE_CHECKING is defined.
10684 (byte_debug_flag): Remove.
10685 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10686 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10688 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10690 Avoid code repetition in marker-related functions.
10691 * marker.c (attach_marker): New function.
10692 (Fset_marker, set_marker_restricted, set_marker_both)

10695 Consistently rename charno to charpos.
10696 (marker_position): Add eassert.
10697 (marker_byte_position): Convert to eassert.
10699 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10701 Simplify list operations in unchain_overlay and unchain_marker.

10712 * editfns.c (buildmark): Remove.
10713 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10714 (save_restriction_save): Use build_marker.
10715 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10716 * window.c (save_window_save): Likewise.
10718 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10720 Do not use Fdelete_overlay in delete_all_overlays
10721 to avoid redundant calls to unchain_overlay.

10723 (delete_all_overlays, Fdelete_overlay): Use it.
10724 * minibuf.c (get_minibuffer): Fix comment.
10726 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10728 Port to OpenBSD 5.1 amd64.
10729 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10730 This is needed for OpenBSD, and should be harmless on all BSD systems.
10731 Also, include <sys/sysctl.h>, as it should be available on all
10732 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10733 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10734 use p_pid member, not kp_proc.pid.
10736 2012-07-06 Glenn Morris <rgm@gnu.org>
10738 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10740 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

10751 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10753 Omit needless casts involving void * pointers and allocation.
10754 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10755 as the former is more robust if P's type is changed.
10756 Prefer xzalloc to xmalloc + memset 0.
10757 Simplify malloc-or-realloc to realloc.
10758 Don't worry about xmalloc returning a null pointer.
10759 Prefer xstrdup to xmalloc + strcpy.
10760 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10762 * keyboard.c (apply_modifiers_uncached): Prefer local array to

10767 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10768 hscroll is larger than the line width. Fixes long and futile
10769 looping inside extend_face_to_end_of_line (on a TTY) producing
10770 glyphs that are not needed and thrown away.
10772 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10774 * marker.c (set_marker_restricted_both): Simplify by using
10777 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10779 * editfns.c (region_limit): Simplify by using clip_to_bounds.

10788 followed by gtk_box_set_homogeneous (Bug#11768).
10789 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10790 (update_theme_scrollbar_width, xg_create_scroll_bar):
10791 Use gtk_scrollbar_new (Bug#11768).
10792 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
10793 (is_box_type): New function (Bug#11768).
10794 (xg_tool_item_stale_p): Call is_box_type.
10795 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10796 with default display (Bug#11768).
10798 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10800 * xdisp.c (window_hscroll_limited): New function.
10801 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10802 coordinates when window's hscroll is set to insanely large
10803 values. (Bug#11857)
10805 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10868 * fileio.c (time_error_value): Check the right error number.
10869 Problem reported by Troels Nielsen in
10870 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10872 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10874 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10875 This should be fixed in a better way; see Eli Zaretskii in
10876 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10877 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10879 * fileio.c (time_error_value): Rename from special_mtime.
10880 The old name's problems were noted by Eli Zaretskii in
10881 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10883 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10884 This variable's comment says Emacs needs at least one GDB-visible
10885 symbol of type enum pvec_type, to work around GDB problems.
10886 The symbol's value doesn't matter.
10888 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10889 that causes compilation to fail on pre-C99 compilers.
10891 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10893 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

10896 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10898 * buffer.c (init_buffer_once): Fix initialization of
10899 headers for buffer_defaults and buffer_local_symbols.
10900 Reported by Juanma Barranquero <lekktu@gmail.com>.
10902 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10904 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10905 * lisp.h (enum pvec_type): Use fewer bits.
10906 (PSEUDOVECTOR_SIZE_BITS): New constant.
10907 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10908 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10909 change in pvec_type.
10910 (PSEUDOVECTOR_TYPEP): New macro.
10911 (TYPED_PSEUDOVECTORP): Use it.
10912 * fns.c (internal_equal): Adapt code to extract pvectype.
10913 * emacs.c (gdb_pvec_type): Update type.
10914 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10915 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10916 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10917 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10918 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10919 abusing vector->header.next.nbytes.
10920 (live_vector_p): Use PVEC_TYPE.
10921 (mark_object): Adapt code to extract pvectype. Use switch.
10923 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10925 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10926 Tighten new eassert a bit.
10928 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10930 Fix compilation with --enable-gcc-warnings and -O1
10931 optimization level.
10932 * doprnt.c (doprnt): Change type of tem to int, initialize
10933 to avoid compiler warning. Add eassert.
10934 * search.c (simple_search): Initialize match_byte to avoid
10935 compiler warning. Add eassert.
10937 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10939 Avoid weird behavior with large horizontal scrolls.
10940 Without this change, for example, large hscroll values would
10941 mess up Emacs's display on Fedora 15 x86, presumably due to
10942 overflows in int calculations in the display code.
10943 Also, if buffers had long lines, Emacs would freeze.
10944 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10945 (set_window_hscroll): New function, containing the old guts of
10946 Fset_window_hscroll. Return the clipped value.
10947 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10948 This avoids the need to check against PTRDIFF_MAX.
10950 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10952 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10954 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10956 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10958 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10959 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10960 since GCC 4.4.6 issues a bogus warning for them.
10962 Fix bugs in file timestamp newness comparisons.
10963 * fileio.c (Ffile_newer_than_file_p):
10964 * lread.c (Fload): Use full timestamp resolution of files,
10965 not just the 1-second resolution, so that files that are only
10966 slightly newer still count as newer.
10967 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10968 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10970 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10972 * fileio.c: Improve handling of file time marker. (Bug#11852)
10973 (special_mtime): New function.
10974 (Finsert_file_contents, Fverify_visited_file_modtime):
10975 Use it to set special mtime values consistently.
10977 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
10979 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10980 marker for non-existing file. (Bug#11852)
10982 2012-07-03 Glenn Morris <rgm@gnu.org>
10984 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10985 and did not make it into globals.h).
10987 2012-07-03 Tom Tromey <tromey@redhat.com>
10989 * window.c (Fset_window_margins, Fset_window_fringes)
10990 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
10991 * textprop.c (Fprevious_property_change): No longer static.

11020 * w32term.h: Remove EXFUNs.

11023 * xterm.h: Remove EXFUN.
11025 2012-07-03 Glenn Morris <rgm@gnu.org>
11027 * lisp.h (Frandom): Make it visible to C.
11028 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11029 buffer for invisible buffers. (Bug#1229)
11031 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11033 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11034 values which aren't power of 2.
11035 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11036 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11039 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11041 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11043 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11045 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11047 * alloc.c (allocate_vector_block): Remove redundant
11048 calls to mallopt if DOUG_LEA_MALLOC is defined.
11049 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11050 avoid calls to mallopt if zero_vector is returned.
11052 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11054 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11055 is enabled, avoid dereferencing NULL current_sblock if
11058 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11060 Cleanup basic buffer management.
11061 * buffer.h (struct buffer): Change layout to use generic vector
11062 marking code. Fix some comments. Change type of 'clip_changed'
11063 to bitfield. Remove unused #ifndef old.
11064 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11065 (GET_OVERLAYS_AT): Fix indentation.
11066 (for_each_per_buffer_object_at): New macro.
11067 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

11071 struct buffer. Fix comment.
11072 (mark_overlay): New function.
11073 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11074 Lisp area of struct buffer.
11075 (mark_object): Use it. Adjust marking of misc objects
11076 and related comments.
11078 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11080 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11081 wrapper that is not needed because the wrapped code is a no-op (zero
11082 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11083 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11085 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11087 * alloc.c (mark_buffer): Simplify. Remove prototype.
11088 (mark_object): Add comment. Reorganize marking of vector-like
11089 objects. Use CHECK_LIVE for all vector-like objects except buffers
11090 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11091 Avoid redundant calls to mark_vectorlike for bool vectors.
11093 2012-06-30 Glenn Morris <rgm@gnu.org>
11095 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11097 * epaths.in (PATH_SITELOADSEARCH): New.
11098 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11099 This is rather than relying on --enable-locallisppath elements
11100 having "site-lisp" in their names. (Bug#10208#25, 11658)
11102 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11104 * w32proc.c (sys_select): Accept and ignore one more argument.
11106 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11108 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11109 (pselect) [!MS_DOS]: Redirect to sys_select.
11111 * sysdep.c: Don't include dos.h and dosfns.h.
11113 * process.c (sys_select):
11114 * msdos.c (sys_select): Accept one more argument and ignore it.
11116 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11117 adapt data types and code to that.
11120 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11121 which clashes with the gnulib function of the same name.
11123 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11125 * font.c (font_style_to_value, font_style_symbolic)
11126 (font_prop_validate_style): Add type checks for values in
11129 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11131 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11134 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11136 * xdisp.c (try_window_id): Undo last change.
11138 * w32.c (getwd): Adjust commentary about startup_dir.
11139 (init_environment): Always call sys_access, even in non-MSVC
11140 builds. Don't chdir to the directory of the Emacs executable.
11141 This undoes code from 1997 which was justified by the need to
11142 "avoid conflicts when removing and renaming directories". But its
11143 downside was that every relative file name was being interpreted
11144 relative to the directory of the Emacs executable, which can never
11145 be TRT. In particular, it broke sys_access when called with
11146 relative file names.
11147 (sys_access): Map GetLastError to errno.
11149 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11151 * window.h (struct window): Change type of 'fringes_outside_margins'
11152 to bitfield. Fix comment. Adjust users accordingly.
11153 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
11155 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11158 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11160 * gnutls.c (emacs_gnutls_handshake):
11161 Add QUIT to make the loop interruptible.
11163 2012-06-29 Glenn Morris <rgm@gnu.org>
11165 * charset.c (init_charset): Make lack of etc/charsets fatal.
11167 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11169 * editfns.c (region_limit): Fix type mismatch.
11171 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11173 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11174 undefined. Convert from xassert to eassert.
11175 * nsmenu.m: Convert from xassert to eassert.
11176 * nsterm.m: Likewise.
11178 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
11180 * editfns.c (region_limit): Clip to narrowing (bug#11770).
11182 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11184 Avoid integer overflow on scroll-left and scroll-right.
11185 * window.c (HSCROLL_MAX): New macro.
11186 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11187 overflow when requested scroll falls outside ptrdiff_t range.
11189 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11191 * window.h (struct window): Change type of 'hscroll',
11192 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11193 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11194 Adjust users accordingly.
11195 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11196 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11197 from EMACS_INT to ptrdiff_t.
11198 (make_window): Omit redundant initialization.
11200 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

11217 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11218 adjust comments accordingly.

11331 * alloc.c: Remove build_string.
11332 * lisp.h: Define build_string as static inline. This provides
11333 a better opportunity to optimize away calls to strlen when the
11334 function is called with compile-time constant argument.
11335 * image.c (imagemagick_error): Convert to build_string.
11336 * w32proc.c (sys_spawnve): Likewise.
11337 * xterm.c (x_term_init): Likewise.
11339 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11341 Use sprintf return value instead of invoking strlen on result.
11342 In the old days this wasn't portable, since some sprintf
11343 implementations returned char *. But they died out years ago and
11344 Emacs already assumes sprintf returns int.
11345 Similarly for float_to_string.
11346 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
11347 * ccl.c (ccl_driver):

11351 * print.c (print_object):
11352 * xdisp.c (message_dolog):
11353 * xfns.c (syms_of_xfns):
11354 Use sprintf or float_to_string result to avoid need to call strlen.
11355 * data.c (Fnumber_to_string):
11356 Use make_unibyte_string, since the string must be ASCII.
11357 * lisp.h, print.c (float_to_string): Now returns int length.
11358 * term.c (produce_glyphless_glyph):
11359 Use sprintf result rather than recomputing it.
11361 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
11362 * Makefile.in (ALL_CFLAGS):
11363 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
11364 * gmalloc.c, regex.c: Include <config.h> unconditionally.
11366 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11368 * dispextern.h (xstrcasecmp): Define to library function
11369 strcasecmp if available.

11385 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
11387 * gtkutil.c (get_utf8_string): Remove redundant assignment.
11388 sprintf already null-terminates its output.
11390 * xfns.c (x_window): Remove redundant cast.
11392 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11394 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11395 `const char *' to `char *' to avoid compiler warning.
11397 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11399 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11400 instead of truncating it to 63 (admittedly a generous limit).
11402 * process.c: Fix spelling and caps in comments.
11404 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
11406 * emacs.c (setpgrp): Remove definition, unused.

11420 * s/ms-w32.h (struct timespec): Definition moved from
11421 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
11423 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

11453 Remove unnecessary forward decls.
11455 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11457 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
11458 * lisp.h (WAIT_READING_MAX): New macro.
11459 * dispnew.c (Fsleep_for, sit_for):
11460 * keyboard.c (kbd_buffer_get_event):
11461 * process.c (Faccept_process_output):
11462 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11463 This improves on the previous patch, which introduced a bug
11464 when time_t is unsigned and as wide as intmax_t.
11465 See <http://bugs.gnu.org/9000#51>.
11467 2012-06-23 Eli Zaretskii <eliz@gnu.org>
11469 * dispnew.c (sit_for, Fsleep_for):
11470 * keyboard.c (kbd_buffer_get_event):
11471 * process.c (Faccept_process_output): Avoid compiler warnings when
11472 comparing a 32-bit time_t with a 64-bit INTMAX_MAX.
11474 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
11476 * makefile.w32-in: Update dependencies.
11478 * w32.c (ltime): Add return type and declare static.
11479 (w32_get_internal_run_time): Remove usused variable `time_100ns'.

11485 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
11487 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
11488 not make_lisp_timeval, when the argument is of type EMACS_TIME.
11490 2012-06-23 Eli Zaretskii <eliz@gnu.org>
11492 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
11493 last argument of make_unibyte_string.
11495 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
11496 language ID in the event parameters.
11498 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11499 event.code, not the obscure "character set ID".
11501 2012-06-23 Chong Yidong <cyd@gnu.org>
11503 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
11505 2012-06-23 Eli Zaretskii <eliz@gnu.org>
11507 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

11517 in the logic of incrementing and decrementing the value of
11518 use_relocatable_buffers.

11526 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
11527 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
11528 Don't assume EMACS_TIME and struct timeval are the same type.
11530 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
11532 Support higher-resolution time stamps (Bug#9000).
11533 The time stamps are only nanosecond-resolution at the C level,
11534 since that's the best that any real-world system supports now.
11535 But they are picosecond-resolution at the Lisp level, as that's
11536 easy, and leaves room for future OS improvements.
11538 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11541 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11542 Don't get current time unless it's needed.
11544 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11545 now provides it if it's absent.
11546 (start_atimer): Port to higher-res time stamps.
11547 Check for time stamp overflow. Don't get current time more
11548 often than is needed.
11550 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11551 Include systime.h, not time.h.
11552 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11554 * dired.c: Include stat-time.h.
11555 (Ffile-attributes): File times now have higher resolution.
11557 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11558 (struct image): Timestamp now has higher resolution.
11560 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11561 has at least microseconds now. All uses removed.
11562 (update_frame, update_single_window, update_window, update_frame_1)
11563 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11564 (duration_to_sec_usec): Remove; no longer needed.
11566 * editfns.c (time_overflow): Now extern.
11567 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
11568 (float-time, Fformat_time_string, Fcurrent_time_string)

11571 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
11572 (decode_time_components, lisp_seconds_argument): New functions.
11573 (make_time): Now static.
11574 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11575 Report an error if the time is invalid, rather than having the caller
11578 * fileio.c: Include <stat-time.h>
11579 (Fcopy_file): Copy higher-resolution time stamps.
11580 Prefer to set the time stamp via a file descriptor if that works.
11581 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11582 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11583 (Fvisited_file_modtime, Fset_visited_file_modtime):
11584 Support higher-resolution time stamps.
11586 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11588 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11590 * image.c (prepare_image_for_display, clear_image_cache)
11591 (lookup_image): Port to higer-resolution time stamps.
11593 * keyboard.c (start_polling, bind_polling_period):
11594 Check for time stamp overflow.
11595 (read_char, kbd_buffer_get_event, timer_start_idle)
11596 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11597 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11598 Port to higher-resolution time stamps. Do not assume time_t is signed.
11599 (decode_timer): New function. Timers are now vectors of length 9,
11600 not 8, to accommodate the picosecond component.
11601 (timer_check_2): Use it.
11603 * nsterm.m (select_timeout, timeval_subtract): Remove.
11604 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11605 as they're a bit more accurate and handle overflow better.
11606 (ns_select): Change prototype to be compatible with pselect.
11607 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11608 * nsterm.h (ns_select): Adjust prototype.
11610 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11611 us-resolution time stamps.
11612 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11614 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11616 * lisp.h (time_overflow): New decl.
11617 (wait_reading_process_output): First arg is now intmax_t, not int,
11618 to accommodate larger waits.
11620 * process.h (struct Lisp_Process.read_output_delay):
11621 Now counts nanoseconds, not microseconds.
11622 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11624 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11625 (wait_reading_process_output):
11626 Port to ns-resolution time stamps.
11627 (Faccept_process_output, wait_reading_process_output):
11628 Check for time stamp overflow. Do not assume time_t is signed.
11629 (select_wrapper): Remove; we now use pselect.
11630 (Fprocess_attributes): Now generates ns-resolution time stamps.
11632 * sysdep.c: Include utimens.h. Don't include utime.h
11633 or worry about struct utimbuf; gnulib does that for us now.
11634 (gettimeofday): Remove; gnulib provides a substitute.
11635 (make_timeval): New function.
11636 (set_file_times): Now sets ns-resolution time stamps.
11637 New arg FD; all uses changed.
11638 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11639 (system_process_attributes):
11640 Now returns ns-resolution time stamp. All uses changed.
11641 Check for time stamp overflow.
11643 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11644 provides a substitute now.
11646 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11647 since it guarantees struct timespec.
11648 (EMACS_TIME): Now struct timespec, so that we can support
11649 ns-resolution time stamps.
11650 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11651 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11652 (EMACS_USECS): Remove.
11653 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11654 so multiply the arg by 1000 before storing it.
11655 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11657 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11658 Port to ns-resolution time stamps.
11659 (EMACS_TIME_NEG_P): Remove; replaced by....
11660 (EMACS_TIME_SIGN): New macro.
11661 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
11662 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
11663 (set_file_times, make_time, lisp_time_argument): Adjust signature.
11664 (make_timeval, make_lisp_time, decode_time_components): New decls.
11665 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11666 that it mishandled time_t overflow. You can't compare by subtracting!
11667 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11668 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11670 * term.c: Include <sys/time.h>.
11671 (timeval_to_Time): New function, for proper overflow wraparound.
11672 (term_mouse_position, term_mouse_click): Use it.
11674 * undo.c (record_first_change): Support higher-resolution time stamps
11675 in the undo buffer.
11676 (Fprimitive_undo): Use them when restoring time stamps.
11678 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11679 (w32_get_internal_run_time):
11680 Port to higher-resolution Emacs time stamps.
11681 (ltime): Now accepts single 64-bit integer, as that's more convenient
11684 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11686 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11687 for compatibility with pselect. Support ns-resolution time stamps.
11689 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11691 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11692 Check for time stamp overflow, and support ns-resolution time stamps.
11694 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11695 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11696 (timeval_subtract): Remove; no longer needed.
11697 (XTflash, XTring_bell, x_wait_for_event):
11698 Port to ns-resolution time stamps. Don't assume time_t is signed.
11700 2012-06-22 Chong Yidong <cyd@gnu.org>
11702 * xdisp.c (x_consider_frame_title): Revert last change.
11704 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11706 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11707 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11708 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11709 staticidx goes up to 1597 out of 1600 = 0x640.)
11711 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11713 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
11714 Otherwise, the umask might be mistakenly 0 while handling input signals.
11716 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

12167 * buffer.c (buffer_local_value_1): New function, split from
12168 Fbuffer_local_value; can return Qunbound.
12169 (Fbuffer_local_value): Use it.
12170 (Vmode_line_format): Docstring tweaks.
12172 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
12174 * sysdep.c (system_process_attributes): Improve comment.
12176 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
12178 * keyboard.c: Export real-this-command to Elisp.
12179 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
12180 and DEFVAR it. Update all users.
12182 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
12184 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12186 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12187 Convert pctcpu and pctmem to Lisp float properly.
12188 Let the compiler fold better, as 100.0/0x8000 is exact.
12190 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
12192 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
12195 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
12197 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
12199 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
12201 For a 'struct window', replace some Lisp_Object fields to
12202 bitfields where appropriate, remove unused fields.
12203 * window.h (struct window): Remove unused 'last_mark_x' and
12204 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12205 change its type from Lisp_Object to bitfield.
12206 Change type of 'force_start', 'optional_new_start',
12207 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
12208 fields from Lisp_Object to bitfield. Adjust users accordingly.
12210 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12212 Pacify gcc -Wdouble-precision when using Xaw.
12213 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
12214 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12215 Use 'float' consistently, rather than 'float' in most places
12216 and 'double' in a couple of places.
12218 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12220 * xdisp.c (handle_stop): Detect whether we have overlay strings
12221 loaded by testing it->current.overlay_string_index to be
12222 non-negative, instead of checking whether n_overlay_strings is
12223 positive. (Bug#11587)
12225 2012-05-31 Chong Yidong <cyd@gnu.org>
12227 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
12229 * doc.c (Fsubstitute_command_keys): Doc fix.
12231 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12233 * search.c (search_buffer): Remove calls to
12234 r_alloc_inhibit_buffer_relocation, as it is now called by
12235 maybe_unify_char, which was the cause of relocation of buffer text
12238 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12240 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12241 for the duration of call to load_charset, to avoid problems with
12242 callers of maybe_unify_char that access buffer text through C
12245 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12246 decrement the inhibition flag, instead of just setting or
12249 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12251 Remove obsolete '#define static' cruft.
12252 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12253 This #undef was "temporary" in 2000; it is no longer needed
12254 now that '#define static' has gone away.
12255 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12256 (gray_bitmap_bits): Remove; no longer needed.
12257 All uses replaced with definiens.
12258 * xterm.c: Include "bitmaps/gray.xbm".
12260 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
12262 Clean up __executable_start, monstartup when --enable-profiling.
12263 The following changes affect the code only when profiling.
12264 * dispnew.c (__executable_start): Rename from safe_bcopy.
12265 Define only on platforms that need it.
12266 * emacs.c: Include <sys/gmon.h> when profiling.
12267 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
12268 (__executable_start): Remove decl, since lisp.h does it now.
12269 (safe_bcopy): Remove decl; no longer has that name.
12270 (main): Coalesce #if into single bit of code, for simplicity.
12271 Cast pointers to uintptr_t, since standard libraries want integers
12273 * lisp.h (__executable_start): New decl.
12275 2012-05-31 Glenn Morris <rgm@gnu.org>
12277 * image.c (Fimagemagick_types): Doc fix.
12279 2012-05-30 Jim Meyering <meyering@redhat.com>
12281 * callproc.c (Fcall_process_region): Include directory component
12282 in mkstemp error message (Bug#11586).
12284 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
12286 * alloc.c, lisp.h (make_pure_vector): Now static.
12288 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
12290 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
12291 Move to byte-run.el.

12293 * data.c (Fdefalias): Purify definition, except for keymaps.
12294 (Qdefun): Move from eval.c.
12295 * lisp.h (Qdefun): Remove.
12296 * lread.c (read1): Tiny simplification.
12298 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
12300 Do not create empty overlays with the evaporate property (Bug#9642).
12301 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12302 Bug#9642, but explicitly check that the buffer the overlay would
12303 be moved to is live and rearrange lines to make sure that errors
12304 will not put the overlay in an inconsistent state.
12305 (Fdelete_overlay): Cosmetics.
12307 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12309 * w32term.c (my_bring_window_to_top): New function.
12310 (x_raise_frame): Use handle returned by DeferWindowPos, which
12311 could be different from the original one.
12312 Call my_bring_window_to_top instead of my_set_foreground_window.
12315 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
12316 by calling BringWindowToTop.
12318 * w32term.h (WM_EMACS_BRINGTOTOP): New message.

12321 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12323 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12324 This avoids undefined behavior that might cause the eassert
12325 to not catch an out-of-range value.
12327 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12329 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
12330 Update dependencies.
12332 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12334 * bidi.c (bidi_mirror_char): Fix last change.
12336 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
12338 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
12339 when referring to sectname field in printf format.
12341 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
12343 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12344 Only r_alloc_inhibit_buffer_relocation needed to be added;
12345 the others were already declared.
12347 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12348 before checking whether it's out of range. Put the check inside
12350 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12352 2012-05-27 Ken Brown <kbrown@cornell.edu>
12354 * callproc.c (Fcall_process): Restore a line that was accidentally
12355 commented out in the 2011-02-13 change (bug#11547).
12357 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12359 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12360 defined on ralloc.c.
12362 * buffer.c [REL_ALLOC]: Remove prototypes of
12363 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12364 they are now on lisp.h.
12366 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12368 * search.c (search_buffer): Use it to inhibit relocation of buffer
12369 text while re_search_2 is doing its job, because re_search_2 is
12370 passed C pointers to buffer text. (Bug#11519)
12372 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12373 Update value to 24.
12375 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12376 state after an additional call to move_it_in_display_line_to, keep
12377 the values of it->max_ascent and it->max_descent found for the
12379 (pos_visible_p): Revert the comparison against bottom_y to what it
12380 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12383 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12385 Fix coding-related core dumps with gcc -ftrapv.
12386 The code was computing A - B, where A and B are pointers, and B is
12387 random garbage. This can lead to core dumps on platforms that
12388 have special pointer registers, and it also leads to core dumps on
12389 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12390 A - B only when B is initialized properly.
12391 * coding.c (coding_set_source, coding_set_destination): Return void.
12392 (coding_change_source, coding_change_destinations): New functions,
12393 with the old behaviors of coding_set_source and coding_set_destination.
12394 All callers that need an offset changed to use these new functions.
12396 2012-05-26 Glenn Morris <rgm@gnu.org>
12398 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
12400 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12402 Extend mouse support on W32 text-mode console.
12403 * xdisp.c (draw_row_with_mouse_face):
12404 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12406 * w32console.c: Include window.h.
12407 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12409 (initialize_w32_display): Initialize mouse-highlight data.
12411 * w32inevt.c: Include termchar.h and window.h.
12412 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12413 moves, call note_mouse_highlight. If help_echo changed, call
12414 gen_help_event to produce help-echo message in the echo area.
12415 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12418 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12420 * lread.c (read1): Simplify slightly to avoid an overflow warning
12421 with GCC 4.7.0 on x86-64.
12423 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12425 * bidi.c (bidi_mirror_char): Revert last change: an int is
12426 definitely wide enough here.
12428 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12430 Fix integer width and related bugs (Bug#9874).
12431 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
12432 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
12433 (string_bytes, check_sblock, allocate_string_data):
12434 (compact_small_strings, Fmake_bool_vector, make_string)
12435 (make_unibyte_string, make_multibyte_string)
12436 (make_string_from_bytes, make_specified_string)
12437 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
12438 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
12440 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12441 (allocate_pseudovector):
12442 Use int, not EMACS_INT, where int is wide enough.
12443 (inhibit_garbage_collection, Fgarbage_collect):
12444 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12445 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12446 int might not be wide enough.
12447 (bidi_cache_search, bidi_cache_find, bidi_init_it)
12448 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
12449 (bidi_at_paragraph_end, bidi_find_paragraph_start)
12450 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
12451 (bidi_level_of_next_char, bidi_move_to_visually_next):
12452 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12453 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
12454 (Fkill_buffer, Fset_buffer_major_mode)
12455 (advance_to_char_boundary, Fbuffer_swap_text)
12456 (Fset_buffer_multibyte, overlays_at, overlays_in)
12457 (overlay_touches_p, struct sortvec, record_overlay_string)
12458 (overlay_strings, recenter_overlay_lists)
12459 (adjust_overlays_for_insert, adjust_overlays_for_delete)
12460 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
12461 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
12462 (Foverlay_recenter, last_overlay_modification_hooks_used)
12463 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
12464 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12465 (validate_region): Omit unnecessary test for b <= e,
12466 since that's guaranteed by the previous test.
12467 (adjust_overlays_for_delete): Avoid pos + length overflow.
12468 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12469 (report_overlay_modification):
12470 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12471 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12472 Omit pointer cast, which isn't needed anyway, and doesn't work
12473 after the EMACS_INT -> ptrdiff_t change.
12474 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12475 * buffer.h: Adjust decls to match defn changes elsewhere.
12476 (struct buffer_text, struct buffer):
12477 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12478 Use EMACS_INT, not int, where int might not be wide enough.
12479 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12480 not int, to avoid needless 32-bit limit on 64-bit hosts.
12481 (exec_byte_code): Use tighter memory-full test, one that checks
12482 for alloca overflow. Don't compute the address of the object just
12483 before an array, as that's not portable. Use EMACS_INT, not
12484 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12485 * callint.c (Fcall_interactively):
12486 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12487 * callproc.c (call_process_kill, Fcall_process):
12488 Don't assume pid_t fits into an Emacs fixnum.
12489 (call_process_cleanup, Fcall_process, child_setup):
12490 Don't assume pid_t fits into int.
12491 (call_process_cleanup, Fcall_process, delete_temp_file)
12492 (Fcall_process_region):
12493 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12494 (Fcall_process): Simplify handling of volatile integers.
12495 Use int, not EMACS_INT, where int will do.
12496 * casefiddle.c (casify_object, casify_region, operate_on_word)
12497 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
12498 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12499 (casify_object): Avoid integer overflow when overallocating buffer.
12500 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12501 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12502 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12503 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12504 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
12505 integers are now checked earlier. All uses replaced with XINT.
12507 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12508 For CCL_MapSingle, check that content and value are in int range.
12509 (ccl_driver, Fregister_code_conversion_map):
12510 Check that Vcode_version_map_vector is a vector.
12511 (resolve_symbol_ccl_program): Check that vector header is in range.
12512 Always copy the vector, so that we can check its contents reliably
12513 now rather than having to recheck each instruction as it's being
12514 executed. Check that vector words fit in 'int'.
12515 (ccl_get_compiled_code, Fregister_ccl_program)
12516 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12517 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12518 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12519 contents are in range.
12520 (Fccl_execute_on_string): Check that status is in range.
12521 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12522 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12523 Accept and return EMACS_INT, not int, because callers can pass values
12524 out of 'int' range.
12525 (c_string_width, strwidth, lisp_string_width, chars_in_text)
12526 (multibyte_chars_in_text, parse_str_as_multibyte)
12527 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
12528 (str_as_unibyte, str_to_unibyte, string_count_byte8)
12529 (string_escape_byte8, Fget_byte):
12530 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12531 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12532 avoid mishandling large integers.
12533 * character.h: Adjust decls to match defn changes elsewhere.
12534 * charset.c (load_charset_map_from_file, find_charsets_in_text)
12535 (Ffind_charset_region):
12536 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12537 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
12538 (load_charset_map_from_vector, Fdefine_charset_internal):
12539 Don't assume fixnum fits in int.
12540 (load_charset_map_from_vector, Fmap_charset_chars):
12541 Remove now-unnecessary CHECK_NATNUMs.
12542 (Fdefine_charset_internal): Check ranges here, more carefully.
12543 Don't rely on undefined behavior with signed left shift overflow.
12544 Don't assume unsigned int fits into fixnum, or that fixnum fits
12545 into unsigned int. Don't require max_code to be a valid fixnum;
12546 that's not true for gb10830 4-byte on a 32-bit host. Allow
12547 invalid_code to be a cons, for the same reason. Require code_offset
12548 to be a character. Avoid int overflow if max_char is close
12550 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12551 this is intended anyway and avoids some undefined behavior.
12552 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12553 INDEX_TO_CODE_POINT, as that's what it expects.
12554 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12555 * charset.h (DECODE_CHAR): Return int, not unsigned;
12556 this is what was intended anyway, and it avoids undefined behavior.
12557 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12558 integer-overflow issues.
12559 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12560 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12561 where the argument is EMACS_INT, and this behavior is not intended.
12562 * chartab.c (Fmake_char_table, Fset_char_table_range)
12563 (uniprop_get_decoder, uniprop_get_encoder):
12564 Don't assume fixnum fits in int.
12565 * cmds.c (move_point): New function, that does the gist of
12566 Fforward_char and Fbackward_char, but does so while checking
12567 for integer overflow more accurately.
12568 (Fforward_char, Fbackward_char): Use it.
12569 (Fforward_line, Fend_of_line, internal_self_insert)
12570 (internal_self_insert):
12571 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12572 Fix a FIXME, by checking for integer overflow when calculating
12573 target_clm and actual_clm.
12574 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
12575 (CODING_ENCODE_CHAR, CODING_CHAR_CHARSET, CODING_CHAR_CHARSET_P)

13254 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
13257 This directory predates autoconf and is no longer needed nowadays.
13258 Move its few remaining bits of functionality to where they're needed.
13259 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
13260 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
13261 * m/template.h: Remove.
13262 * Makefile.in (M_FILE): Remove. All uses removed.
13263 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
13264 * lisp.h (USE_LSB_TAG):
13265 * mem-limits.h (EXCEEDS_LISP_PTR):
13266 Use VAL_MAX, not VALBITS, in #if.
13267 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
13268 (EMACS_UINT): Define unconditionally now.
13269 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
13270 (BITS_PER_EMACS_INT): New constants, replacing
13271 what used to be in config.h, but not useful in #if.
13272 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
13273 define them any more.
13274 (VAL_MAX): New macro.
13276 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
13277 BITS_PER_EMACS_INT, in #if.
13278 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
13279 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
13280 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
13281 * s/ms-w32.h (DATA_START):
13282 Move here from removed file m/intel386.h.
13283 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
13284 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
13286 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
13288 Assume C89 or later.
13289 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
13290 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
13292 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
13293 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
13294 * textprop.c, tparam.c (NULL): Remove.
13295 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
13296 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
13297 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
13298 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
13299 * xterm.c (input_signal_count): Assume volatile works.
13301 2012-05-21 Ken Brown <kbrown@cornell.edu>
13303 * xgselect.c (xg_select): Fix first argument in call to 'select'
13306 2012-05-20 Ken Brown <kbrown@cornell.edu>
13308 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
13309 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
13311 2012-05-19 Ken Brown <kbrown@cornell.edu>
13313 * xfns.c (x_in_use): Remove `static' qualifier.
13314 * xterm.h (x_in_use): Declare.
13315 * xgselect.c: Include xterm.h.
13316 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
13317 and `display_arg' (bug#9754).
13319 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
13321 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
13323 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
13324 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
13326 2012-05-18 Eli Zaretskii <eliz@gnu.org>
13328 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
13330 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
13331 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
13333 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
13334 reference to image_cache->refcount.
13335 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
13337 2012-05-17 Juri Linkov <juri@jurta.org>
13339 * search.c (Fword_search_regexp, Fword_search_backward)
13340 (Fword_search_forward, Fword_search_backward_lax)
13341 (Fword_search_forward_lax): Move functions to isearch.el
13342 (bug#10145, bug#11381).
13344 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13346 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13348 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13350 * lread.c (init_obarray): Declare Qt and Qnil as special.
13352 2012-05-14 Glenn Morris <rgm@gnu.org>
13354 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13355 Put "libexec" before "bin", for the sake of init_callproc_1.
13357 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13359 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13361 * unexaix.c: Port to more-recent AIX compilers.
13362 (report_error, report_error_1, make_hdr, copy_sym)
13363 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13364 Make arguments const char *, not char *, to avoid violations of C
13365 standard and to fix some AIX warnings reported by Gilles Pion.
13367 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13369 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13370 already have overlays loaded.
13371 (handle_single_display_spec): Before returning without displaying
13372 fringe bitmap, synchronize the bidi iterator with the main display
13373 iterator, by calling iterate_out_of_display_property.
13374 (iterate_out_of_display_property): Detect buffer iteration by
13375 testing that it->string is a Lisp string.
13376 (get_next_display_element): When the current object is exhausted,
13377 and there's something on it->stack, call set_iterator_to_next to
13378 proceed with what's on the stack, instead of returning zero.
13379 (set_iterator_to_next): If called at the end of a Lisp string,
13380 proceed to consider_string_end without incrementing string
13381 position. Don't increment display vector index past the end of
13382 the display vector. (Bug#11417)
13383 (pos_visible_p): Don't report a position visible when move_it_to
13384 stopped at the last line of window, which happens to be scanned
13385 backwards by the bidi iteration. (Bug#11464)
13387 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13389 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13390 and right-margin display specs even if the spec is invalid or we
13391 are on a TTY, and thus unable to display on the fringes.
13392 That's because the text with the property will not be displayed anyway,
13393 so we need to signal to the caller that this is a "replacing"
13394 display spec. This fixes display when the spec is invalid or we
13397 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13399 * unexaix.c (make_hdr): Fix typo in prototype.
13400 This bug broke the build on AIX. Problem reported by Gilles Pion.
13402 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13404 * keyboard.c (kbd_buffer_get_event): Read special events also in
13405 batch mode. (Bug#11415)
13407 2012-05-12 Glenn Morris <rgm@gnu.org>
13409 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13411 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13413 * lisp.mk (lisp): Add newcomment.elc.
13415 2012-05-12 Glenn Morris <rgm@gnu.org>
13417 * Makefile.in (MKDIR_P): New, set by configure.
13418 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13420 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13422 Remove unused function hourglass_started.
13423 * dispextern.h (hourglass_started):
13424 * w32fns.c (hourglass_started):
13425 * xdisp.c (hourglass_started): Remove.
13427 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13429 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13430 Update dependencies.
13432 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13434 * xgselect.c (xg_select): Put maxfds+1 into a var.
13435 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13437 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13439 2012-05-10 Dave Abrahams <dave@boostpro.com>
13441 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13442 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13444 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13446 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13447 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13448 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13449 Initialize xd_registered_buses.
13451 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13453 Untag more efficiently if USE_LSB_TAG.
13454 This is based on a proposal by YAMAMOTO Mitsuharu in
13455 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13456 For an admittedly artificial (nth 8000 longlist) benchmark on
13457 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13458 Emacs's overall text size by 1%.
13459 * lisp.h (XUNTAG): New macro.
13460 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13461 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13462 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13463 * eval.c (Fautoload):
13464 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13465 * frame.h (XFRAME): Use XUNTAG.
13467 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13468 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13469 Remove unportable assumptions about print widths of types like
13471 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13472 intptr_t when converting between pointer and integer, to avoid GCC
13473 warnings about wrong width.
13475 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13477 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13478 stack for each reader_thread, instead of defaulting to 8MB
13479 determined by the linker. This avoids failures in creating
13480 subprocesses on Windows 7, see the discussion in this thread:
13481 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13483 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13485 Fix up display of the *Minibuf-0* buffer in the mini window.
13486 * keyboard.c (read_char): Don't clear the echo area if there's no
13488 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13489 contents of *Minibuf-0*) if there's no message displayed in its stead.
13491 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13493 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13496 2012-05-06 Chong Yidong <cyd@gnu.org>
13498 * lisp.mk (lisp): Update.
13500 2012-05-05 Jim Meyering <meyering@redhat.com>
13502 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13504 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13506 * data.c (PUT_ERROR): New macro.
13507 (syms_of_data): Use it. Add new error type `user-error'.
13508 * undo.c (user_error): New function.
13509 (Fprimitive_undo): Use it.
13510 * print.c (print_error_message): Adjust print style for `user-error'.
13511 * keyboard.c (user_error): New function.
13512 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13514 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13516 Do not limit current-time-string to years 1000..9999.
13517 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13518 (Fcurrent_time_string): Support any year that is supported by the
13519 underlying localtime representation. Don't use asctime, as it
13520 has undefined behavior for years outside the range -999..9999.
13522 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13524 Fix race conditions involving setenv, gmtime, localtime, asctime.
13525 Without this fix, interrupts could mess up code that uses these
13526 nonreentrant functions, since setting TZ invalidates existing
13527 tm_zone or tzname values, and since most of these functions return
13528 pointers to static storage.
13529 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13530 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13531 Grow the critical sections to include not just invoking
13532 localtime/gmtime, but also accessing these functions' results
13533 including their tm_zone values if any, and any related TZ setting.
13534 (format_time_string): Last arg is now struct tm *, not struct tm **,
13535 so that the struct tm is saved in the critical section.
13536 All callers changed. Simplify allocation of initial buffer, partly
13537 motivated by the fact that memory allocation needs to be outside
13538 the critical section.
13540 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13542 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13543 with RESET_INTERVAL.
13545 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13546 Remove duplicated buffer name initialization.
13548 2012-05-02 Jim Meyering <jim@meyering.net>
13550 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13552 * xfns.c (x_window): Use xstrdup (Bug#11375).
13554 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13556 * xdisp.c (pos_visible_p): If already at a newline from the
13557 display string before the 'while' loop, don't walk back the glyphs
13558 from it3.glyph_row. Solves assertion violation when the display
13559 string begins with a newline (egg.el). (Bug#11367)
13561 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13563 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13566 2012-05-01 Glenn Morris <rgm@gnu.org>
13568 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13569 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13570 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13571 All were removed before 23.1.
13573 * dispnew.c: Remove HAVE_LIBNCURSES test;
13574 it is always true on relevant platforms.
13576 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13577 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13579 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13581 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13583 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13584 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13587 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13589 Do not avoid creating empty evaporating overlays (Bug#9642).
13590 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13591 That is, do not delete an evaporating overlay if it becomes
13592 empty after its bounds are adjusted to fit within its buffer.
13593 This fix caused other problems, and I'm reverting it until we get
13594 to the bottom of them.
13596 2012-04-27 Chong Yidong <cyd@gnu.org>
13598 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13600 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13602 * xdisp.c (pos_visible_p): If the window start position is beyond
13603 ZV, start the display from buffer beginning. Prevents assertion
13604 violation in init_iterator when the minibuffer window is scrolled
13605 via the scroll bar.
13607 * window.c (window_scroll_pixel_based): Likewise.
13609 2012-04-27 Chong Yidong <cyd@gnu.org>
13611 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13613 2012-04-27 Glenn Morris <rgm@gnu.org>
13615 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13616 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13618 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13620 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13621 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13623 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13625 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13626 display element, check also the underlying string or buffer
13627 character. (Bug#11341)
13629 * w32menu.c: Include w32heap.h.
13630 (add_menu_item): If the call to AppendMenuW (via
13631 unicode_append_menu) fails, disable Unicode menus only if we are
13632 running on Windows 9X/Me.
13634 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13636 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13637 (xgetint): Add missing shift for LSB tags.
13639 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13641 * keyboard.c (read_char): Don't wipe echo area for select window
13642 events: These might get delayed via `mouse-autoselect-window'
13645 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13647 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13648 manipulation of :loaded-from data.
13650 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13652 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13653 now a cons (bug#11311).
13655 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13657 Do not create empty overlays with the evaporate property (Bug#9642).
13658 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13659 if it becomes empty after its bounds are adjusted to fit within
13660 its buffer. Without this fix, in a nonempty buffer (let ((o
13661 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13662 yields an empty overlay that has the evaporate property, which is
13663 not supposed to happen.
13665 Fix minor GTK3 problems found by static checking.
13666 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13667 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13668 (struct _EmacsFixedClass, emacs_fixed_get_type):
13669 Move decls here from emacsgtkfixed.h, since they needn't be public.
13670 (emacs_fixed_get_type): Now static.
13671 (emacs_fixed_class_init): Omit unused local.
13672 (emacs_fixed_child_type): Remove; unused.
13673 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13674 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13675 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13676 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
13677 (EMACS_FIXED_GET_CLASS): Remove; unused.
13678 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
13680 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
13681 Problem reported by Juanma Barranquero for Windows -Wunused-function.
13683 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13685 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13686 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13687 (__malloc_size_t, __malloc_ptrdiff_t):

13778 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13780 * sysdep.c [__FreeBSD__]: Minor cleanups.
13781 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13782 Use Emacs indenting style more consistently. Avoid some casts.

13864 New extern decls, to avoid calling undeclared functions.
13865 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13866 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13867 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13868 (NEED_MEM_INSERT): New macro.
13869 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13870 Remove one incorrect comment and fix another.

13885 Remove decls. This fixes an "It stinks!".
13887 * alloc.c (which_symbols): Fix alignment issue / type clash.
13889 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
13891 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

13906 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
13907 * s/netbsd.h, s/sol2-6.h:
13908 Remove definition of GC_MARK_STACK, since the default now works.
13909 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13910 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's

13912 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13914 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

13937 2012-04-11 Daniel Colascione <dancol@dancol.org>
13939 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13940 against is gone. It's better to use vfork now so that when Cygwin
13941 gains a new, working vfork, we use it automatically (bug#10398).
13943 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

13964 being loaded (bug#10424).
13966 2012-04-09 Glenn Morris <rgm@gnu.org>
13968 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

13989 2012-04-09 Chong Yidong <cyd@gnu.org>
13991 * eval.c (Fuser_variable_p, user_variable_p_eh)

13996 * minibuf.c (Fread_variable): Callers changed.
13998 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14000 * xdisp.c (set_cursor_from_row): If the display string appears in
14001 the buffer at position that is closer to point than the position
14002 after the display string, display the cursor on the first glyph of
14003 the display string. Fixes cursor display when a 'display' text
14004 property immediately follows invisible text. (Bug#11094)
14006 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14008 composite.c: use 'double' consistently
14009 * composite.c (get_composition_id): Use 'double' consistently
14010 instead of converting 'float' to 'double' and vice versa; this is
14011 easier to understand and avoids a GCC warning.
14013 2012-04-09 Glenn Morris <rgm@gnu.org>
14015 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14016 preparation for dumping it with emacs. (Bug#4789)

14038 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14039 (mark_memory): Mark Lisp_Objects only if pointers might hide in

14058 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14059 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14060 [!WINDOWSNT]: New macros.
14061 (init_libxml2_functions, libxml2_loaded_p): New functions.
14062 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14063 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14064 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14065 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14067 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14068 Call init_libxml2_functions before calling libxml2 functions.
14069 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14071 * emacs.c: Don't include libxml/parser.h.
14072 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14073 xmlCleanupParser directly.
14075 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14077 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14079 * indent.c (Fvertical_motion): If there is a display string at
14080 point, use it.vpos to compute how many lines to backtrack after
14081 move_it_to point. (Bug#11133)
14083 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14085 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14086 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14087 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14088 macros related to unification of CJK characters. For the details,
14089 see the discussion following the message here:
14090 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

14103 * w32menu.c (is_simple_dialog): Properly check lisp types.
14106 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14108 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14109 position we get to after a call to move_it_to fails the
14110 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14111 only if we wind up in a string from display property. (Bug#11063)
14113 * window.c (Fdelete_other_windows_internal): Invalidate the row
14114 and column information about mouse highlight, so that redisplay
14115 restores it after reallocating the glyph matrices. (Bug#7464)
14117 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14118 string comes from a `display' text property, use the buffer
14119 position of that property as if we actually saw that position in
14121 (move_it_by_lines): Remove the assertion that
14122 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14123 violated when there's a before-string at the beginning of a line.
14126 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14128 * xdisp.c (append_space_for_newline): If the default face was
14129 remapped, use the remapped face for the appended newline.
14130 (extend_face_to_end_of_line): Use the remapped default face for
14131 extending the face to the end of the line.
14132 (display_line): Call extend_face_to_end_of_line when the default
14133 face was remapped. (Bug#11068)
14135 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14137 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

14143 2012-03-27 Glenn Morris <rgm@gnu.org>
14145 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
14148 2012-03-26 Kenichi Handa <handa@m17n.org>

14155 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14156 (command_loop_1): Use it; inhibit selection update for
14157 handle-select-window too (Bug#8996).
14159 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
14161 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14163 2012-03-25 Kenichi Handa <handa@m17n.org>
14165 * dispextern.h (struct glyph): Change the bit length of
14166 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14168 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14170 * s/ms-w32.h (tzname): Include time.h before redirecting to
14171 _tzname. Fixes the MSVC build. (Bug#9960)
14173 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
14175 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
14178 * xterm.c (XTread_socket): Only modify handling_signal if
14179 !SYNC_INPUT. (Bug#11080)
14181 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14183 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14184 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14185 when fetching a multibyte character consumes more bytes than
14186 CHAR_BYTES returns, due to unification of CJK characters in
14187 string_char. (Bug#11073)
14189 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14191 * process.c (wait_reading_process_output): Handle pty disconnect
14192 by refraining from sending oneself a SIGCHLD (bug#10933).

14221 it fit in a valid range (Bug#11003).
14223 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14225 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14226 that is not from display property, accept the row as a "cursor
14227 row" if one of the string's character has a non-nil `cursor'
14228 property. Fixes cursor positioning when there are newlines in
14229 overlay strings, e.g. in icomplete.el. (Bug#11035)
14231 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14233 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14235 2012-03-12 Chong Yidong <cyd@gnu.org>
14237 * eval.c (inhibit_lisp_code): Rename from
14238 inhibit_window_configuration_change_hook; move from window.c.
14240 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14241 * window.c (run_window_configuration_change_hook)
14242 (syms_of_window): Callers changed.

14261 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
14262 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14265 2012-03-03 Glenn Morris <rgm@gnu.org>
14267 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14269 2012-03-02 Eli Zaretskii <eliz@gnu.org>
14271 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
14272 position past the first glyph_row that ends at ZV. (Bug#10902)
14273 (redisplay_window, next_element_from_string): Fix typos in
14275 (redisplay_window): Pass to move_it_vertically the margin in
14276 pixels, not in screen lines.
14278 2012-03-02 Glenn Morris <rgm@gnu.org>
14280 * buffer.c (buffer-list-update-hook): Doc fix.
14282 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14284 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14285 push_it before setting up the iterator for the first overlay
14286 string, even if we have an empty string loaded.
14287 (next_overlay_string): If there's an empty string on the iterator
14288 stack, pop the stack. (Bug#10903)
14290 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14292 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14293 Suggested by Stefan Monnier in
14294 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14295 * alloc.c (widen_to_Lisp_Object): New static function.
14296 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14297 and widening them to Lisp_Objects. This would work even if
14298 USE_LSB_TAG is defined and wide integers are used, which might
14299 happen in a future version of Emacs.
14301 2012-02-25 Chong Yidong <cyd@gnu.org>
14303 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
14306 * xselect.c (Fx_selection_exists_p): Doc fix.
14307 (x_clipboard_manager_save_all): Print an informative message
14308 before saving to clipboard manager.
14310 2012-02-24 Chong Yidong <cyd@gnu.org>
14312 * keyboard.c (process_special_events): Handle all X selection
14313 requests in kbd_buffer, not just the next one (Bug#8869).
14315 2012-02-23 Chong Yidong <cyd@gnu.org>
14317 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14318 call when setting menu-bar-lines and tool-bar-lines parameters.
14319 (unwind_create_frame_1): New helper function.
14321 * window.c (inhibit_window_configuration_change_hook): New var.

14332 * fileio.c (Vfile_name_handler_alist): Doc fix.
14334 * buffer.c (Fget_file_buffer): Protect against invalid file
14335 handler return value.
14337 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
14339 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
14340 when computing $valmask.
14342 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14343 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14344 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14345 It's useless in that case, and it can cause problems on hosts
14346 that allocate halves of EMACS_INT values separately.
14347 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14348 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14349 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14350 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14351 it avoids undefined behavior on hosts where shifting right by more
14352 than the word width has undefined behavior.
14354 2012-02-19 Chong Yidong <cyd@gnu.org>
14356 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14357 (Funhandled_file_name_directory, Ffile_name_as_directory)
14358 (Fdirectory_file_name, Fexpand_file_name)
14359 (Fsubstitute_in_file_name): Protect against invalid file handler
14360 return values (Bug#10845).
14362 2012-02-18 Eli Zaretskii <eliz@gnu.org>
14364 * .gdbinit (pitx): Fix incorrect references to fields of the

14374 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14376 2012-02-15 Chong Yidong <cyd@gnu.org>
14378 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14379 marked as special. Also, starting docstrings with * is obsolete.

14394 2012-02-12 Chong Yidong <cyd@gnu.org>
14396 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14397 as that creates a dangerous corner case.
14399 * window.c (Fdelete_window_internal): Invalidate the mouse
14400 highlight (Bug#9904).
14402 2012-02-12 Glenn Morris <rgm@gnu.org>

14407 * nsselect.m (Fx_own_selection_internal)
14408 (Fx_disown_selection_internal, Fx_selection_exists_p)
14409 (Fx_selection_owner_p, Fx_get_selection_internal):
14410 Sync docs and argument specs with the xselect.c versions.
14412 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

14432 2012-02-07 Chong Yidong <cyd@gnu.org>
14434 * buffer.c (Fbuffer_local_variables)
14435 (buffer_lisp_local_variables): Handle unbound vars correctly;
14436 don't let Qunbound leak into Lisp.
14438 2012-02-07 Glenn Morris <rgm@gnu.org>
14440 * image.c (Fimagemagick_types): Doc fix.
14442 * image.c (imagemagick-render-type): Change it from a lisp object
14443 to an integer. Move the doc here from the lisp manual.

14463 Include --enable-checking, if specified, in the return value.
14465 2012-02-04 Martin Rudalics <rudalics@gmx.at>
14467 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols

14472 * keyboard.c (adjust_point_for_property): Don't position point
14473 before BEGV. (Bug#10696)
14475 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
14477 Handle overflow when computing char display width (Bug#9496).
14478 * character.c (char_width): Return EMACS_INT, not int.
14479 (char_width, c_string_width): Check for overflow when
14480 computing the width; this is possible now that individual
14481 characters can have unbounded width. Problem introduced
14482 by merge from Emacs 23 on 2012-01-19.
14484 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

14506 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
14508 (x_produce_glyphs): If the component of a composition is a null
14509 string, set it->pixel_width to 1 to avoid zero-width glyph.
14511 2012-02-01 Eli Zaretskii <eliz@gnu.org>
14513 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
14514 first 2 arguments are identical. This makes inserting large
14515 output from a subprocess an order of magnitude faster on
14516 MS-Windows, where all sbrk'ed memory is always contiguous.
14518 2012-01-31 Glenn Morris <rgm@gnu.org>

14574 * character.c (char_width): New function.
14575 (Fchar_width, c_string_width, lisp_string_width):

14601 2012-01-11 Glenn Morris <rgm@gnu.org>
14603 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs

14608 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
14610 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
14611 Update template values to be closer to their typical values these days.
14613 2012-01-09 Eli Zaretskii <eliz@gnu.org>

15131 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
15132 Otherwise, valgrind does not work on some platforms.
15133 Problem reported by Andreas Schwab in
15134 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
15135 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15136 is set, removing the need for VIRT_ADDRESS_VARIES.
15137 (PURE_P): Use a more-efficient implementation that needs just one
15138 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
15139 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
15140 to 4 (xorl, subq, cmpq, setbe).
15141 * alloc.c (pure): Always extern now, since that's the
15142 VIRT_ADDR_VARIES behavior.
15143 (PURE_POINTER_P): Use a single comparison, not two, for
15144 consistency with the new puresize.h.
15145 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
15146 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

15154 behave as if the cursor position were at the window margin.
15156 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15157 and the cursor position is out of bounds, behave as if the cursor
15158 position were at the window margin. (Bug#10075)
15160 2011-11-18 Chong Yidong <cyd@gnu.org>
15162 * window.c (Fwindow_combination_limit): Make first argument

15183 * xdisp.c (row_hash): New function, body extracted from
15184 compute_line_metrics.
15185 (compute_line_metrics): Call row_hash, instead of computing the
15188 * dispnew.c (verify_row_hash): Call row_hash for computing the
15189 hash code of a row, instead of duplicating code from xdisp.c.
15191 * dispextern.h (row_hash): Add prototype.
15193 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

15221 (Fsplit_window_internal, saved_window)
15222 (Fset_window_configuration, save_window_save): Rename all
15223 occurrences of window_nest to window_combination_limit.

15229 2011-11-14 Eli Zaretskii <eliz@gnu.org>
15231 * xdisp.c (display_line): Move the call to
15232 highlight_trailing_whitespace before the call to
15233 compute_line_metrics, since the latter needs to see the final
15234 faces of all the glyphs to compute ROW's hash value.
15235 Fixes assertion violations in row_equal_p. (Bug#10035)
15237 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
15239 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
15240 just return (bug#10044).
15242 2011-11-12 Eli Zaretskii <eliz@gnu.org>
15244 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
15245 with user-defined heap size. Bump the default size of the temacs
15246 heap to 27MB, to avoid memory warning when running temacs.

15249 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
15250 current_matrix and desired_matrix. (Bug#9990)
15251 (verify_row_hash) [XASSERTS]: New function.

15298 Avoid some portability problems by eschewing 'extern inline' functions.
15299 The trivial performance wins aren't worth the portability hassles; see
15300 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
15302 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

15376 (window_box_width, window_box_left, window_box_left_offset)
15377 (window_box_right, window_box_right_offset): Declare extern.
15378 Otherwise, these inline functions do not conform to C99 and
15379 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15380 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15381 * intervals.c (adjust_intervals_for_insertion)

15384 (static_offset_intervals): Remove.
15385 (offset_intervals): Rewrite using the old contents of
15386 static_offset_intervals. The old version didn't conform to C99
15387 because an extern inline function contained a reference to an
15388 identifier with static linkage.

15441 (unwind_create_frame): New function (Bug#9943).
15442 (Fx_create_frame): Restructure code to be more similar to the one in
15443 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

15541 HAVE_GTK3 (Bug#9869).
15543 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
15544 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
15546 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
15548 * xterm.c: Declare x_handle_net_wm_state to return int.
15549 (handle_one_xevent): Check if we are iconified but don't have
15550 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
15551 (get_current_wm_state): Return non-zero if not hidden,
15552 check for _NET_WM_STATE_HIDDEN (Bug#9893).
15553 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
15554 (x_handle_net_wm_state): Return what get_current_wm_state returns.
15555 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
15557 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
15559 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
15560 so that this new function doesn't get optimized away by a
15561 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
15563 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
15565 * frame.h (MOUSE_HL_INFO): Remove excess parens.
15567 2011-10-29 Eli Zaretskii <eliz@gnu.org>
15569 Fix the `xbytecode' command.
15570 * .gdbinit (xprintbytestr): New command.
15571 (xwhichsymbols): Rename from `which'; all callers changed.
15572 (xbytecode): Print the byte-code string as well.
15574 2011-10-29 Kim Storm <storm@cua.dk>
15576 * alloc.c (which_symbols): New function.
15578 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
15580 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
15583 2011-10-29 Glenn Morris <rgm@gnu.org>
15585 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
15586 Not clear what it was for, and it causes various bugs. (Bug#9839)
15588 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15590 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
15591 possible random value that matches one of those tested as
15592 condition to clear the mouse face.
15594 2011-10-28 Chong Yidong <cyd@gnu.org>
15596 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
15598 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
15600 * window.c (make_window): Initialize phys_cursor_on_p.
15602 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
15604 * lisp.h (struct Lisp_Symbol): Update comments.
15606 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
15608 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
15610 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15612 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
15613 <oslsachem@gmail.com> for helping to debug this.
15615 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
15616 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
15617 (g_b_init_get_glyph_outline_w): New static variables.
15618 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
15619 (GetGlyphOutlineW_Proc): New typedefs.
15620 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
15621 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
15623 (w32font_open_internal, compute_metrics):
15624 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15625 instead of calling the "wide" APIs directly.
15627 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
15629 * w32.h (syms_of_w32font): Add prototype.
15631 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15633 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
15634 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
15635 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
15636 (Fmove_to_window_line): Doc fix.
15638 2011-10-27 Chong Yidong <cyd@gnu.org>
15640 * process.c (make_process): Set gnutls_state to NULL.
15642 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15643 non-NULL, regardless of GNUTLS_INITSTAGE.
15644 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
15645 an error. Set process slots as soon as we allocate them.
15647 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
15649 2011-10-27 Chong Yidong <cyd@gnu.org>
15651 * gnutls.c (emacs_gnutls_deinit): New function.
15652 Deallocate credentials structures as well as calling gnutls_deinit.
15653 (Fgnutls_deinit, Fgnutls_boot): Use it.
15655 * process.c (make_process): Initialize GnuTLS credentials to NULL.
15656 (deactivate_process): Call emacs_gnutls_deinit.
15658 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15660 * image.c (x_create_x_image_and_pixmap):
15661 * w32.c (sys_rename, w32_delayed_load):
15662 * w32font.c (fill_in_logfont):
15663 * w32reg.c (x_get_string_resource): Silence compiler warnings.
15665 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
15667 * w32fns.c (w32_default_color_map): New function,
15668 extracted from Fw32_default_color_map.
15669 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
15671 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
15673 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
15675 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
15677 * keyboard.c (test_undefined): New function (bug#9751).
15678 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
15680 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
15682 * sysdep.c (init_sys_modes): Fix the check for the controlling
15683 terminal (Bug#6649).
15685 2011-10-20 Eli Zaretskii <eliz@gnu.org>
15687 * dispextern.h (struct bidi_it): New member next_en_type.
15689 * bidi.c (bidi_line_init): Initialize the next_en_type member.
15690 (bidi_resolve_explicit_1): When next_en_pos is valid for the
15691 current character, check also for next_en_type being WEAK_EN.
15692 (bidi_resolve_weak): Don't enter the expensive loop if the current
15693 position is before next_en_pos. Record the bidi type of the first
15694 non-ET, non-BN character we find, in addition to its position.
15695 (bidi_level_of_next_char): Invalidate next_en_type when
15696 next_en_pos is over-stepped.
15698 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15700 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15701 * editfns.c: Rewrite current-time-zone so that it invokes
15702 the equivalent of (format-time-string "%Z") to get the time zone name.
15703 This fixes a bug when the time zone name contains characters that
15704 need converting from the system time locale to Emacs internal format.
15705 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15706 that patch fixed format-time-string to do the conversion, but
15707 I forgot to fix current-time-zone.
15708 (format_time_string): New function, containing most of
15709 what Fformat_time_string used to contain.
15710 (Fformat_time_string): Rewrite in terms of format_time_string.
15711 This doesn't change this function's behavior.
15712 (current-time-zone): Rewrite to use format_time_string.
15713 This fixes the bug reported by Michael Schierl in
15714 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15715 Jason Rumney's 2007-06-07 change worked around this bug, but
15717 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15719 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15721 * xdisp.c (start_display): If the character at POS is displayed
15722 via a display vector, reset IT->current.dpvec_index to zero.
15723 (try_window_reusing_current_matrix): If a line ends in a display
15724 vector or the next line starts in a display vector, continue
15725 redrawing the window even though the character position of
15726 start_row was reached.
15729 2011-10-18 Chong Yidong <cyd@gnu.org>
15731 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15732 with nobreak-char-display too.
15734 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15736 Fix part 3 of bug#9771.
15737 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15738 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15739 non-neutral characters if the current character is a paragraph
15740 separator (a.k.a. Newline). This avoids running the same
15741 expensive loop twice, once when we consume the preceding newline
15742 and the other time when the line actually needs to be displayed.
15743 Avoid the loop when we see neutrals on the base embedding level
15744 following a character whose directionality is the same as the
15745 paragraph's. This avoids running the expensive loop when a line
15746 ends in a long sequence of neutrals, like control characters.
15747 Add assertion against STRONG_AL type. Slightly rearrange code
15748 that determines the type of a neutral given the first non-neutral
15750 (bidi_level_of_next_char): Set next_en_pos to zero when
15751 invalidating its info.
15753 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15755 * xdisp.c (push_display_prop): Determine whether to record string
15756 or buffer position by IT->string, not by IT->method. Allow
15757 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15758 (move_it_vertically_backward): Don't look for character position
15759 immediately after the newline when in a continuation line.
15762 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15764 * window.c (coordinates_in_window): Rewrite and delabelize
15765 vertical border check. (Bug#5357) (Bug#9618)
15767 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15769 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15770 errors in XSetWindowBorder (bug#9310).
15772 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15774 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15775 avoid crash when xmalloc overrun checking is enabled.
15777 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15779 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15780 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15781 cursor motion with <left> and <right> arrow keys.
15783 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15784 some callers set that themselves.
15786 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15788 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15789 display string and the previous row comes from the same string and
15790 is empty. (Bug#9739) (Bug#9738)
15792 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15794 * doc.c (get_doc_string): Encode file name (bug#9735).
15796 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15798 * bidi.c (bidi_level_of_next_char):
15799 * xdisp.c (get_visually_first_element): Remove old incorrect
15800 comments regarding the Unicode Line Separator character.
15802 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15804 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15806 * alloc.c (Fgc_status): Do not access beyond zombies array
15807 boundary if nzombies > MAX_ZOMBIES.
15808 * alloc.c (dump_zombies): Add missing format specifier.
15810 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15812 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15813 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15815 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15816 Some packages use them to denote characters with modifiers.
15818 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15820 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15821 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15822 matching a pp-number. Rename parameter var to var1.
15824 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15826 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15828 2011-10-08 Glenn Morris <rgm@gnu.org>
15830 * callint.c (Fcall_interactively): Give a more explicit error for the
15831 'c' case with a non-character input. (Bug#8479)
15833 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15835 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15837 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15838 lines that are hscrolled on the left.
15840 * dispnew.c (buffer_posn_from_coords): Account for a possible
15841 presence of header-line. (Bug#4426)
15843 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15845 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15846 Don't advertise functionality which we discourage or doesn't work.
15848 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15850 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15851 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15852 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15853 this makes Emacs dump core during garbage collection on rare
15854 occasions. sizeof is obviously inferior to offsetof here, so
15855 stick with offsetof.
15856 (GC_POINTER_ALIGNMENT): New macro.
15857 (mark_memory): Omit 3rd (offset) arg; caller changed.
15858 Don't assume EMACS_INT alignment is the same as pointer alignment.
15860 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15862 * keyboard.c (read_key_sequence_remapped): New var.
15863 (read_key_sequence): Compute remapping in the right buffer.
15864 (command_loop_1): Use read_key_sequence's remapping directly.
15866 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15868 * dired.c (file_name_completion): Don't expand file name.
15869 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15870 before checking file name handler.
15872 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15873 they've been requested explicitly (bug#9591).
15875 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15877 * keymap.c (Fsingle_key_description): Use make_specified_string
15878 instead of build_string to build string from push_key_description.
15881 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15883 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15884 This fixes a Y2038 bug on 64-bit hosts.
15885 * buffer.c (reset_buffer):
15886 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15887 (Fclear_buffer_auto_save_failure):
15888 Use 0, not -1, to represent an unset failure time, since time_t
15889 might not be signed.
15891 Remove dependency on glibc malloc internals.
15892 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15893 Move back here from lisp.h, but with their new implementations.
15894 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15895 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15896 * charset.c (charset_table_init): New static var.
15897 (syms_of_charset): Use it instead of xmalloc. This removes a
15898 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15899 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15900 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15901 Move back to alloc.c.
15902 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15903 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15905 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15907 * nsterm.m (windowDidResize): Call x_set_window_size only when
15908 ns_in_resize is true. Otherwise set pixelwidth/height and
15909 call change_frame_size (Bug#9628).
15911 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15913 Port --enable-checking=all to Fedora 14 x86-64.
15914 * charset.c (syms_of_charset): Also account for glibc malloc's
15915 internal overhead when calculating the initial malloc maximum.
15917 Port --enable-checking=all to Fedora 14 x86.
15918 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15920 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15921 (overrun_check_realloc, overrun_check_free):
15922 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15923 That way, xmalloc returns a properly-aligned pointer even if
15924 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15925 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15926 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15927 into account when calculating the initial malloc maximum.
15928 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15929 Move here from alloc.c, so that charset.c can use it too.
15930 Properly align; the old code wasn't right for common 32-bit hosts
15931 when configured with --enable-checking=all.
15932 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15933 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15935 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15937 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15940 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15942 * xdisp.c (compute_display_string_end): If there's no display
15943 string at CHARPOS, return -1.
15945 * bidi.c (bidi_fetch_char): When compute_display_string_end
15946 returns a negative value, treat the character as a normal
15947 character not covered by a display string. (Bug#9624)
15949 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15951 * lread.c (Fread_from_string): Fix typo in docstring.
15953 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15955 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15956 newline, reseat the iterator instead of bidi-iterating there one
15957 character at a time. (Bug#9610)
15958 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15959 TO_CHARPOS if the bidi iterator is at base embedding level.
15961 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15963 * lread.c (readevalloop): Use correct code for NBSP.
15964 (read1): Likewise. (Bug#9608)
15966 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15968 * dbusbind.c (Fdbus_register_signal): When service is not
15969 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15971 2011-09-25 Glenn Morris <rgm@gnu.org>
15973 * buffer.c (truncate-lines): Doc fix.
15975 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15977 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15978 (Fset_window_next_buffers): Doc fix.
15980 2011-09-24 Glenn Morris <rgm@gnu.org>
15982 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15984 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15986 Fix minor problems found by static checking.
15987 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15988 * indent.c (Fvertical_motion): Fix == vs = typo.
15990 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15992 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15993 Default value is now t. Doc fix.
15995 * indent.c (Fvertical_motion): Compute and apply the overshoot
15996 logic when moving up, not only when moving down. Fix the
15997 confusing name and values of the it_overshoot_expected variable;
15998 logic changes accordingly. (Bug#9254) (Bug#9549)
16000 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16001 CHARPOS is covered by a display string which includes newlines.
16002 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16003 is covered by a display string with embedded newlines.
16005 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16007 * dbusbind.c (Fdbus_register_signal): Add match rule to
16008 Vdbus_registered_objects_table. (Bug#9581)
16009 (Fdbus_register_method, Vdbus_registered_objects_table):
16012 2011-09-24 Jim Meyering <meyering@redhat.com>
16014 do not ignore write error for any output size
16015 The previous change was incomplete.
16016 While it makes emacs --batch detect the vast majority of stdout
16017 write failures, errors were still ignored whenever the output size is
16018 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16019 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16020 && echo FAIL: ignored write error
16021 FAIL: ignored write error
16022 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16023 && echo FAIL: ignored write error
16024 FAIL: ignored write error
16025 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16027 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16029 * emacs.c (Fkill_emacs): In noninteractive mode exit
16030 non-successfully if a write error occurred on stdout. (Bug#9574)
16032 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16034 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16037 * dispextern.h (struct it): Update the comment documenting what
16040 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16042 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16043 a display string, extend search for cursor position to end of row.
16044 (find_row_edges): If the row ends in a newline from a display
16045 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16046 Handle the case of a display string with multiple newlines.
16047 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16048 non-empty line. Fixes confusing cursor motion with arrow keys at
16049 the beginning of a line that starts with whitespace.
16051 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16053 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16056 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16058 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16059 boolean (Bug#9154).
16061 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16063 * xdisp.c (display_line): Record maximum and minimum buffer
16064 positions even if no glyphs were produced (e.g., by a zero-width
16065 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16066 buffer positions that will be removed from the glyph row because
16068 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16069 column is beyond frame width: don't subtract 1 "pixel" when
16070 computing width of the stretch.
16071 (reseat_at_next_visible_line_start): Undo the change made on
16072 2011-09-17 that saved paragraph information and restored it after
16073 the call to `reseat'. (Bug#9545)
16075 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16077 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16078 and turn window cursor on if cleared (Bug#9415).
16080 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16082 * search.c (boyer_moore): Take unibyte characters from pattern
16083 literally. (Bug#9458)
16085 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16087 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16089 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16091 Fix minor problem found by static checking.
16092 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16093 initialized, to pacify gcc -Wuninitialized.
16095 * fileio.c: Report proper errno when syscall falls.
16096 (Finsert_file_contents): Save and restore errno,
16097 so that report_file_error outputs the correct diagnostic.
16098 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16100 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16102 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16104 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16106 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16107 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16109 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16111 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16112 about the current paragraph and restore it after the call to reseat.
16114 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16115 (bidi_find_paragraph_start): Search back for paragraph beginning
16116 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16117 (bidi_move_to_visually_next): Only trigger paragraph-related
16118 computations when the last character is a newline or at EOB, not
16119 just any NEUTRAL_B. (Bug#9470)
16121 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16122 truncated lines if point is covered by a display string. (Bug#9524)
16124 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16126 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16127 (cons_to_x_long): New function.
16128 (lisp_data_to_selection_data): Use it. Correct the test for
16129 short-versus-long data; it was negated. Break out of vector
16130 loop, for efficiency, when a long datum is discovered.
16132 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16134 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16136 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16138 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16139 GCC PR/17406) by declaring this function with external scope.
16141 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16143 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16144 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16146 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16148 * editfns.c (Fformat): Correctly handle text properties on "%%".
16150 2011-09-15 Eli Zaretskii <eliz@gnu.org>
16152 * xterm.c (x_draw_composite_glyph_string_foreground):
16153 * w32term.c (x_draw_composite_glyph_string_foreground):
16154 * term.c (encode_terminal_code):
16155 * composite.c (composition_update_it, get_composition_id):
16156 * xdisp.c (get_next_display_element)
16157 (fill_composite_glyph_string): Add comments about special meaning
16158 of TAB characters in a composition.
16160 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16162 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16163 This occurs when processing a multibyte format.
16164 Problem reported by Wolfgang Jenker.
16166 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16168 * xdisp.c (try_cursor_movement): Only check for exact match if
16169 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16171 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16173 Remove unused external symbols.
16174 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16175 * xdisp.c (calc_pixel_width_or_height): Now static.
16176 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16177 * indent.c (check_display_width):
16178 * w32term.c: Fix comment to match code.
16179 * xterm.c, xterm.h (x_catching_errors): Remove.
16181 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16183 * xselect.c: Use signed conversions more consistently (Bug#9498).
16184 (selection_data_to_lisp_data): Assume incoming selection data are
16185 signed integers, not unsigned. This is to be consistent with
16186 outgoing selection data, which was modified to use signed integers
16187 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16188 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16189 expects long, not unsigned long.
16191 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16193 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16194 computation of loop end. Reported by Johan Bockgård
16197 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16199 * frame.c (Fother_visible_frames_p): Function deleted.
16201 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16203 * indent.c (compute_motion): Process display vector front to back
16204 rather than the other way around. (Bug#2496)
16206 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16208 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16210 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16212 * minibuf.c (Fread_from_minibuffer): Doc fix.
16214 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16216 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16217 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16219 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16221 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16222 value for non-existent files.
16224 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16226 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16227 set its "size" to -1. This will set the modtime_size field of
16228 the corresponding buffer to -1, which is what
16229 verify-visited-file-modtime expects for files that do not exist.
16232 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16234 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16236 * lisp.h: ... from here. push_key_description is no longer
16237 defined in keyboard.c, so its declaration should not be in
16238 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16239 logically belongs with push_key_description.
16241 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16243 * buffer.h: Include <sys/types.h> instead of <time.h>.
16244 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16245 Problem reported by Herbert J. Skuhra.
16247 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16249 * xml.c (parse_region): Make the parsing work for
16250 non-comment-starting XML files again (bug#9144).
16252 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16254 * image.c (gif_load): Fix calculation of bottom and right corner.
16257 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16259 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16260 redisplay in small windows.
16262 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16264 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16266 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16268 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16269 Operate on live windows only.
16271 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16273 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16275 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16277 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16278 only under bidi iteration.
16280 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16282 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16284 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16286 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16287 Without this fix, the command to link temacs failed due to an
16288 undefined symbol __builtin_isnan. This is because
16289 /usr/include/iso/math_c99.h #defines isnan(x) to
16290 __builtin_isnan(x), but the bundled gcc, which identifies itself
16291 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16293 * floatfns.c (isnan): #undef, and then #define to a clone of
16295 (Fisnan): Always define, since it's always available now.
16296 (syms_of_floatfns): Always define isnan at the Lisp level.
16298 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16300 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16302 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16304 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16305 The previous code assumed that file offsets (off_t values) fit in
16306 EMACS_INT variables, which is not true on typical 32-bit hosts.
16307 The code messed up by falsely reporting buffer overflow in cases
16308 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16309 when "big" contains more than 2**29 bytes, even though this
16310 inserts just one byte and does not overflow the buffer.
16311 (Finsert_file_contents): Store file offsets as off_t
16312 values, not as EMACS_INT values. Check for overflow when
16313 converting between EMACS_INT and off_t. When checking for
16314 buffer overflow or for overlap, take the offsets into account.
16315 Don't use EMACS_INT for small values where int suffices.
16316 When checking for overlap, fix a typo: ZV was used where
16317 ZV_BYTE was intended.
16318 (Fwrite_region): Don't assume off_t fits into 'long'.
16319 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16321 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16323 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16325 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16327 sprintf-related integer and memory overflow issues (Bug#9412).
16329 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16330 (esprintf, exprintf, evxprintf): New functions.
16331 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16332 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16333 (modify_event_symbol): Do not assume that the length of
16334 name_alist_or_stem is safe to alloca and fits in int.
16335 (Fexecute_extended_command): Likewise for function name and binding.
16336 (Frecursion_depth): Wrap around reliably on integer overflow.
16337 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16338 since some callers pass EMACS_INT values.
16339 (Fsingle_key_description): Don't crash if symbol name contains more
16340 than MAX_ALLOCA bytes.
16341 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16342 (get_minibuffer): Arg is now EMACS_INT, not int.
16343 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16344 (esprintf, exprintf, evxprintf): New decls.
16345 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16347 * dbusbind.c (signature_cat): New function.
16348 (xd_signature, Fdbus_register_signal):
16349 Do not overrun buffer; instead, report string overflow.
16351 * dispnew.c (add_window_display_history): Don't overrun buffer.
16352 Truncate instead; this is OK since it's just a log.
16354 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16355 even if the time zone offset is outlandishly large.
16356 Don't mishandle offset == INT_MIN.
16358 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16359 when creating daemon; the previous buffer-overflow check was incorrect.
16361 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16362 which has the guts of the old verror function.
16364 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16365 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16367 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16368 (font_unparse_xlfd): Don't blindly alloca long strings.
16369 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16370 fits in int, when using sprintf. Use single snprintf to count
16371 length of string rather than counting it via multiple sprintfs;
16372 that's simpler and more reliable.
16373 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16374 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16375 sprintf, in case result does not fit in int.
16377 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16378 (fontset_from_font): Print it.
16380 * frame.c (tty_frame_count): Now printmax_t, not int.
16381 (make_terminal_frame, set_term_frame_name): Print it.
16382 (x_report_frame_params): In X, window IDs are unsigned long,
16383 not signed long, so print them as unsigned.
16384 (validate_x_resource_name): Check for implausibly long names,
16385 and don't assume name length fits in 'int'.
16386 (x_get_resource_string): Don't blindly alloca invocation name;
16387 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16390 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16391 (xg_check_special_colors, xg_set_geometry):
16392 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16394 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16395 Use esprintf, not sprintf, in case result does not fit in int.
16397 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16398 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16399 it as a large positive number.
16400 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16401 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16403 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16404 in case result does not fit in int.
16406 * print.c (float_to_string): Detect width overflow more reliably.
16407 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16408 buffer overrun. Don't assume list length fits in 'int'. Treat
16409 print length of 0 as 0, not as infinity; to be consistent with other
16410 uses of print length in this function. Don't overflow print length
16411 index. Don't assume hash table size fits in 'long', or that
16412 vectorlike size fits in 'unsigned long'.
16414 * process.c (make_process): Use printmax_t, not int, to format
16415 process-name gensyms.
16417 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16419 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16420 to avoid potential buffer overrun.
16422 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16423 if X resource line is longer than 512 bytes.
16425 * xfns.c (x_window): Make sprintf buffer a bit bigger
16426 to avoid potential buffer overrun.
16428 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16430 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16432 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16434 Integer overflow fixes for scrolling, etc.
16435 Without these, Emacs silently mishandles large integers sometimes.
16436 For example, "C-u 4294967297 M-x recenter" was treated as if
16437 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16439 * xdisp.c (try_window_id): Check Emacs fixnum range before
16440 converting to 'int'.
16442 * window.c (window_scroll_line_based, Frecenter):
16443 Check that an Emacs fixnum is in range before assigning it to 'int'.
16444 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16445 values converted from Emacs fixnums.
16446 (Frecenter): Don't wrap around a line count if it is out of 'int'
16447 range; instead, treat it as an extreme value.
16448 (Fset_window_configuration, compare_window_configurations):
16449 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16451 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16452 that can exceed INT_MAX. Check that EMACS_INT value is in range
16453 before assigning it to the (possibly-narrower) index.
16454 (match_limit): Don't assume that a fixnum can fit in 'int'.
16456 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16459 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16460 (Fvertical_motion): Don't wrap around LINES values that don't fit
16461 in 'int'. Instead, treat them as extreme values. This is good
16462 enough for windows, which can't have more than INT_MAX lines anyway.
16464 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16466 * Require libxml/parser.h to avoid compilation warning.
16468 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16470 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16471 since this reportedly can destroy thread storage.
16473 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16475 * syntax.c (find_defun_start): Update all cache variables if
16476 exiting early (Bug#9401).
16478 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16480 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16482 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16483 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16484 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16486 * term.c (tty_append_glyph): New function.
16487 (produce_stretch_glyph): Static function and its prototype deleted.
16489 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16492 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16494 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16495 when checking :margin (Bug#9390).
16496 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16497 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16498 so that the name doesn't mislead. All uses changed.
16500 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16502 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after

16508 position beyond to_charpos, if we are scanning backwards.
16509 (move_it_vertically_backward): When DY == 0, make sure we get to
16510 the first character in the line after the newline.
16512 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16514 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16515 (ccl_driver): Do not generate an out-of-range pointer.
16516 (Fccl_execute_on_string): Remove unnecessary check for
16517 integer overflow, noted by Stefan Monnier in
16518 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16519 Remove a FIXME that didn't need fixing.
16520 Simplify the newly-introduced buffer reallocation code.
16522 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16524 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16526 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16528 Integer and memory overflow issues (Bug#9196).
16530 * doc.c (get_doc_string): Rework so that
16531 get_doc_string_buffer_size is the actual buffer size, rather than
16532 being 1 less than the actual buffer size; this makes xpalloc more
16535 * image.c (x_allocate_bitmap_record, cache_image):
16536 * xselect.c (Fx_register_dnd_atom):
16537 Simplify previous changes by using xpalloc.
16539 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16540 since either will do and ptrdiff_t is convenient with xpalloc.

16543 (struct charset_sort_data.priority): Now ptrdiff_t.
16544 (charset_compare): Don't overflow if priorities differ greatly.
16545 (Fsort_charsets): Don't assume list length fits in int.
16546 Check for size-calculation overflow when allocating sort data.
16547 (syms_of_charset): Allocate an initial charset table that is
16548 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16550 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16552 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16553 The actual value is always <= INT_MAX, and leaving it unsigned made
16554 overflow checking harder.
16556 * dispextern.h (struct glyph_matrix.rows_allocated)
16557 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16558 with xpalloc. The values are still always <= INT_MAX.
16560 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16562 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16563 (SAFE_NALLOCA): New macro.

16566 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16567 (set_cache_region, invalidate_region_cache)
16568 (revalidate_region_cache, know_region_cache, region_cache_forward)
16569 (region_cache_backward, pp_cache):
16570 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16571 so that ptrdiff_t * can be passed to xpalloc.
16572 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16573 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16574 (pp_cache): Don't assume cache_len fits in int.
16575 * region-cache.h: Adjust extern decls to match.
16577 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16578 EMACS_INT, since either will do, for xpalloc.
16580 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16581 (xnmalloc, xnrealloc, xpalloc): New functions.
16583 * bidi.c (bidi_shelve_header_size): New constant.
16584 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16585 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16587 * bidi.c (bidi_cache_shrink):
16588 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16590 Don't update size of array until after memory allocation succeeds,
16591 because xmalloc/xrealloc may not return.
16592 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16593 now that we have proper integer overflow checking.
16594 (record_overlay_string, overlay_strings): Catch overflows when
16595 calculating size of overlay_str_buf.
16597 * callproc.c (Fcall_process): Check for size overflow when
16598 calculating size of args2.
16599 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16600 Normally we prefer signed values, but sticking with ptrdiff_t would
16601 require adding more-complicated checks.
16603 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16604 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16605 Redo buffer-overflow calculations to avoid integer overflow.
16606 Add a FIXME comment where memory seems to be over-allocated.
16608 * character.c (Fstring): Check for size-calculation overflow.
16610 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16611 unnecessary integer overflow. Check for size overflow.
16612 (encode_coding_object): Don't update size until xmalloc succeeds.
16614 * composite.c (get_composition_id): Check for overflow in glyph
16615 length calculations.
16617 Integer and memory overflow fixes for display code.
16618 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16619 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)

16634 Don't update size until allocation succeeds.
16635 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not

16641 (message_length): Now ptrdiff_t, not int.
16642 (Fmessage_box): Don't update size until allocation succeeds.
16643 Don't assume message length fits in int.
16644 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16646 * emacs.c (main): Do not reallocate argv, since there is a null at
16647 the end that can be overwritten, and this way there's no need to
16648 worry about size-calculation overflow.
16649 (sort_args): Check for size-calculation overflow.
16651 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16653 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16655 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16656 (x_set_scroll_bar_width, x_figure_window_size):
16657 Check for integer overflow.
16658 (x_set_alpha): Do not assume XINT fits in int.
16660 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16661 This is for the members text_lines, text_cols, total_lines, total_cols,
16662 where the system imposes an 'int' limit.
16664 * fringe.c (Fdefine_fringe_bitmap):
16665 Don't update size until alloc works.
16667 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16668 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16670 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16671 Check for size-calculation overflow.
16672 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16673 do, as we prefer signed integers.
16674 (id_to_widget.max_size, id_to_widget.used)
16675 (xg_store_widget_in_map, xg_remove_widget_from_map)
16676 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16677 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16678 Use and return ptrdiff_t, not int.
16679 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16680 * gtkutil.h: Change prototypes to match the above.
16682 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16683 are duplicate now that they've been promoted to lisp.h.
16684 (x_allocate_bitmap_record, x_alloc_image_color)
16685 (make_image_cache, cache_image, xpm_load):
16686 Don't update size until alloc is done.

16697 Use ptrdiff_t, not int, to count maps.
16698 (read_char_minibuf_menu_prompt): Check for overflow in size
16699 calculations. Don't update size until allocation succeeds.
16700 Redo calculations to avoid overflow.

16729 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16730 for command line length. Do not attempt to address one before the
16731 beginning of an array, as that's not portable.
16733 * term.c (max_frame_lines): Remove; unused.
16734 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
16736 (encode_terminal_code, calculate_costs): Check for size

16760 (Finternal_make_lisp_face, cache_face):
16761 Check for size calculation overflow.
16762 (cache_face): Treat size calculation overflows as if they were

16766 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16767 sizes, since they can exceed INT_MAX in size. Check for size

16771 (xg_select): Check for size calculation overflow.
16772 Don't update size until alloc done.
16774 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16775 as sprintf is limited to int lengths.
16777 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16778 (X_LONG_MIN): New macros.
16779 Use them to make the following changes clearer.
16780 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16781 This change doesn't affect the value now, but it may help remind
16782 future maintainers not to raise the value too much later.
16783 (SELECTION_QUANTUM): Remove, replacing with ...
16784 (selection_quantum): ... new function, which avoids overflow.
16786 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16787 assumption that selection length fits in 'int'.

16799 (x_get_window_property, receive_incremental_selection)
16800 (lisp_data_to_selection_data, x_property_data_to_lisp):

16804 Don't store size until memory allocation succeeds.
16805 (x_get_window_property): Plug memory leak on memory exhaustion.
16806 Don't double-block input; malloc is safe here. Don't assume 2**34
16807 - 4 fits in unsigned long. Add an xassert to check
16808 XGetWindowProperty overflow. Be more careful about overflow
16809 calculations, and distinguish size from memory overflow better.
16810 (receive_incremental_selection): When tracing, don't assume
16811 unsigned int is less than INT_MAX.
16812 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16813 harmful) conversions of unsigned short to int.
16814 (lisp_data_to_selection_data): Don't assume that integers
16815 in the range -65535 through -1 fit in an X unsigned short.
16816 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16817 result parameters unless successful. Rely on cons_to_unsigned
16818 to report problems with elements; the old code wasn't right anyway.
16819 (x_check_property_data): Check for int overflow; we cannot use
16820 a wider type due to X limits.
16821 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

16853 * lisp.h (hash_lookup, hash_put):
16854 * minibuf.c (Ftest_completion):
16855 Use ptrdiff_t for hash table indexes, not int (which is too
16856 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16857 32-bit --with-wide-int hosts).
16859 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16860 Add a FIXME comment about memory leaks.
16861 (syms_of_charset): Don't assume xmalloc returns.
16863 Don't assume that stated character widths fit in int.

16865 * character.h (CHAR_WIDTH):
16866 * indent.c (MULTIBYTE_BYTES_WIDTH):
16867 Use sanitize_char_width to avoid undefined and/or bad behavior
16868 with outlandish widths.
16869 * character.h (sanitize_tab_width): Rename from sanitize_width,
16870 now that we have two such functions. All uses changed.
16871 (sanitize_char_width): New inline function.
16873 Don't assume that tab-width fits in int.
16874 * character.h (sanitize_width): New inline function.
16875 (SANE_TAB_WIDTH): New macro.
16876 (ASCII_CHAR_WIDTH): Use it.

16878 SANE_TAB_WIDTH (current_buffer).
16879 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
16881 * fileio.c: Integer overflow issues with file modes.
16882 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
16884 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
16885 Remove unreachable code.
16886 (read_hex, load_charset_map_from_file): Check for integer overflow.
16888 * xterm.c: Don't go over XClientMessageEvent limit.
16889 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16890 (x_send_scroll_bar_event): Likewise. Check that the size does not
16891 exceed limits imposed by XClientMessageEvent, as well as the usual
16892 ptrdiff_t and size_t limits.
16894 * keyboard.c: Overflow, signedness and related fixes.
16895 (make_lispy_movement): Use same integer type in forward decl
16896 that is used in the definition.
16897 (read_key_sequence, keyremap_step):
16898 Change bufsize argument back to int, undoing my 2011-03-30 change.
16899 We prefer signed types, and int is wide enough here.
16900 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16901 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16902 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16903 length, not size_t. Use ptrdiff_t for index, not int.
16904 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16905 possibility of integer overflow.
16907 Overflow, signedness and related fixes for images.
16909 * dispextern.h (struct it.stack[0].u.image.image_id)
16910 (struct_it.image_id, struct image.id, struct image_cache.size)

16926 when the callers expect that.
16927 (image_ascent): Redo ascent calculation to avoid int overflow.
16928 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
16929 (lookup_image): Remove unnecessary tests.
16930 (xbm_image_p): Locals are now of int, not EMACS_INT,
16931 since parse_image_check makes sure they fit into int.
16932 (png_load, gif_load, svg_load_image):
16933 Prefer int to unsigned where either will do.
16934 (tiff_handler): New function, combining the cores of the
16935 old tiff_error_handler and tiff_warning_handler.
16936 This function is rewritten to use vsnprintf and thereby avoid
16937 stack buffer overflows. It uses only the features of vsnprintf
16938 that are common to both POSIX and native Microsoft.
16939 (tiff_error_handler, tiff_warning_handler): Use it.
16940 (tiff_load, gif_load, imagemagick_load_image):
16941 Don't assume :index value fits in 'int'.
16942 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16943 (imagemagick_load_image): Check that crop parameters fit into
16944 the integer types that MagickCropImage accepts. Don't assume
16945 Vimagemagick_render_type has a nonnegative value. Don't assume
16946 size_t fits in 'long'.
16947 (gs_load): Use printmax_t to print the widest integers possible.
16948 Check for integer overflow when computing image height and width.
16950 2011-08-26 Eli Zaretskii <eliz@gnu.org>
16952 * xdisp.c (redisplay_window): Don't force window start if point

16960 handle_single_display_spec, not just 1 or zero.
16961 (handle_single_display_spec): If the display spec is of the form
16962 `(space ...)', and specifies display in the text area, return 2
16964 (try_cursor_movement): Check for the need to scroll more
16965 accurately, and prefer exact match for point under bidi.
16966 Don't advance `row' beyond the last row of the window.
16968 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
16969 into disp_prop; all users changed.
16971 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
16972 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
16973 for the text covered by the display property.

16983 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
16984 buffers, return left-to-right.
16985 (set_cursor_from_row): Consider candidate row a win if its glyph
16986 represents a newline and point is on that newline. Fixes cursor
16987 positioning on the newline at EOL of R2L text within L2R
16988 paragraph, and vice versa.
16989 (try_cursor_movement): Check continued rows, in addition to
16990 continuation rows. Fixes unwarranted scroll when point enters a
16991 continued line of R2L text within an L2R paragraph, or vice versa.
16992 (cursor_row_p): Consider the case of point being equal to
16993 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
16994 from the end of a short line to the beginning of a continued line
16995 of R2L text within L2R paragraph.
16996 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
16997 composed characters.
16999 * bidi.c (bidi_check_type): Use xassert.

17010 * nsfont.m (ns_otf_to_script): Fix typo.
17012 2011-08-22 Kenichi Handa <handa@m17n.org>
17014 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
17015 extra slot even if the purpose is char-code-property-table.
17017 2011-08-23 Eli Zaretskii <eliz@gnu.org>
17019 * xdisp.c (redisplay_window): When computing centering_position,
17020 account for the height of the header line. (Bug#8874)
17022 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17023 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17024 candidate is selected by the mouse, and that candidate has a
17025 composed character under the mouse.
17027 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17028 coordinates reported by pos-visible-in-window-p for a composed
17029 character in column zero.
17031 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
17033 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
17035 2011-08-22 Eli Zaretskii <eliz@gnu.org>
17037 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
17038 consider it a hit if to_charpos is anywhere in the range of the
17039 composed buffer positions.
17041 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17043 * image.c (gif_load): Don't assume that each subimage has the same
17044 dimensions as the base image. Handle disposal method that is
17045 "undefined" by the gif spec (Bug#9335).
17047 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17049 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17052 2011-08-19 Eli Zaretskii <eliz@gnu.org>
17054 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
17055 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17056 from an Org mode buffer to a Speedbar frame.
17058 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17059 a composition, take its buffer position from IT->cmp_it.charpos.
17060 Fixes cursor positioning at the beginning of a line that begins
17061 with a composed character.
17063 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17065 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17066 character bidirectional type, use STRONG_L instead. Fixes crashes
17067 in a buffer produced by `describe-categories'.
17069 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17070 members before the level stack, so they would be saved and
17071 restored when copying iterator state. Fixes incorrect reordering
17072 around TABs covered by display properties.
17074 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17076 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

17146 * xdisp.c (move_it_in_display_line_to): Don't invoke
17147 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17148 ppos_it. Fixes vertical cursor motion when line beginning is
17149 covered by an image. (Bug#9296)
17151 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17153 * nsterm.h (ns_run_ascript): Declare.

17157 (ns_run_ascript): New function.
17158 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17159 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17160 the event loop. Get status from as_status (Bug#7276).
17162 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17163 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17164 the event loop (Bug#7276).
17166 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

17190 (Fnetwork_interface_list): Allocate in increments of bytes instead
17191 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17192 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17194 (struct ifflag_def): notrailers is smart on OSX.
17195 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17196 Get hardware address with getifaddrs if available.
17198 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17200 * xdisp.c (iterate_out_of_display_property): xassert that
17201 IT->position is set to within IT->object's boundaries. Break from

17204 Set IT->current to match the bidi iterator unconditionally.
17205 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17206 entry. Force push_it to save on the stack the current
17207 buffer/string position, to be restored by pop_it. Fix flags in
17208 the iterator structure wrt the object coming from a display
17209 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17210 properties. (Bug#9284)
17212 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17214 * fontset.c (fontset_get_font_group): Add proper type checks.

17242 restore_point_unwind (Bug#5984).
17244 2011-08-07 Juri Linkov <juri@jurta.org>
17246 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17247 to show the arg `TIME' instead of `TIMEVAL'.

17251 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17252 display property strides EOL and includes a newline, as in
17253 longlines-mode. (Bug#9254)
17254 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17255 word-wrap under bidirectional display. (Bug#9224)
17257 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17258 is non-zero, even if the data buffer is NULL. Fixes a crash in
17259 vertical-motion with longlines-mode. (Bug#9254)
17261 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17263 * bidi.c <bidi_cache_total_alloc>: Now static.

17266 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17269 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17270 amount allocated this far in `bidi_cache_total_alloc'.
17271 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17272 non-zero, only free the data buffer without restoring the cache
17273 contents. All callers changed.
17275 * dispextern.h (bidi_unshelve_cache): Update prototype.
17277 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17278 (move_it_in_display_line, move_it_to)
17279 (move_it_vertically_backward, move_it_by_lines): Replace the call
17280 to xfree to an equivalent call to bidi_unshelve_cache.
17281 (move_it_in_display_line_to): Fix logic of returning
17282 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17284 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17286 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

17337 * bidi.c (bidi_fetch_char): Accept an additional argument
17338 DISP_PROP_P, and pass it to compute_display_string_pos.
17339 Only handle text covered by a display string if DISP_PROP_P is returned
17340 non-zero. All callers of bidi_fetch_char changed.
17342 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17344 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17346 2010-12-03 Don March <don@ohspite.net>
17348 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17349 last character M-[char] is translated to ESC [char] (bug#7541).
17351 2011-08-02 Kenichi Handa <handa@m17n.org>
17353 * lisp.h (uniprop_table): Extern it.
17355 * chartab.c (uniprop_table): Make it non-static.
17357 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17359 * xdisp.c (forward_to_next_line_start): Accept additional argument
17360 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17362 (reseat_at_next_visible_line_start): Use the bidi iterator state
17363 returned by forward_to_next_line_start to restore the state of
17364 it->bidi_it after backing up to previous newline. (Bug#9212)
17366 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17368 * regex.c (re_comp): Protoize.
17369 (re_exec): Fix return type.
17370 (regexec): Fix type of `ret'. (Bug#9203)
17372 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17374 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17375 This is needed if max-image-size is a floating-point number.
17377 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17379 * print.c (print_object): Print empty symbol as ##.
17381 * lread.c (read1): Read ## as empty symbol.
17383 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17385 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17386 setting frame foreground color (Bug#9175).
17387 (x_set_background_color): Likewise.
17389 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17390 contents (Bug#9176).
17391 (EmacsTooltip -init): Remove bezels and add shadows to
17394 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17395 or scroll bar (Bug#8470).
17397 * nsfont.m (nsfont_open): Remove assignment to voffset and
17398 unnecessary vars hshink, expand, hd, full_height, min_height.
17399 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17401 * nsterm.h (nsfont_info): Remove voffset field.
17403 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17405 Implement strike-through and overline on NextStep (Bug#8863).
17407 * nsfont.m (nsfont_open): Use underline position provided by font,
17408 instead of hard-coded value of 2.
17409 (nsfont_draw): Call ns_draw_text_decoration instead.
17411 * nsterm.h: Add declaration for ns_draw_text_decoration.
17413 * nsterm.m (ns_draw_text_decoration): New function for drawing
17414 underline, overline, and strike-through.
17415 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17416 ns_draw_text_decoration. Change treatment of cursor drawing to
17417 accommodate underlining, etc.
17419 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17421 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17424 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17426 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17427 Without this fix, if a signal arrives just after memory fills up,
17428 'malloc' might be invoked reentrantly.
17430 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17431 In other words, assume that every image size is allowed, on non-X
17432 hosts. This assumption is probably wrong, but it lets Emacs compile.
17434 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17436 * regex.c (re_iswctype): Convert return values to boolean.
17438 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17440 * xdisp.c (compute_display_string_pos): Don't use cached display
17441 string position if the buffer had its restriction changed.
17444 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17446 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17448 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17450 Integer signedness and overflow and related fixes. (Bug#9079)
17452 * bidi.c: Integer size and overflow fixes.
17453 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17454 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17455 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17456 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17457 (bidi_find_other_level_edge):
17458 Use ptrdiff_t instead of EMACS_INT where either will do.
17459 This works better on 32-bit hosts configured --with-wide-int.
17460 (bidi_cache_ensure_space): Check for size-calculation overflow.
17461 Use % rather than repeated addition, for better worst-case speed.
17462 Don't set bidi_cache_size until after xrealloc returns, because it
17464 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17465 (bidi_cache_ensure_space): Also check that the bidi cache size
17466 does not exceed that of the largest Lisp string or buffer. See Eli
17467 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17469 * alloc.c (__malloc_size_t): Remove.
17470 All uses replaced by size_t. See Andreas Schwab's note
17471 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17473 * image.c: Improve checking for integer overflow.
17474 (check_image_size): Assume that f is nonnull, since
17475 it is always nonnull in practice. This is one less thing to
17476 worry about when checking for integer overflow later.
17477 (x_check_image_size): New function, which checks for integer
17478 overflow issues inside X.
17479 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17480 This removes the need for a memory_full check.
17481 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17482 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17483 (xbm_read_bitmap_data): Change locals back to 'int', since
17484 their values must fit in 'int'.
17485 (xpm_load_image, png_load, tiff_load):
17486 Invoke x_create_x_image_and_pixmap earlier,
17487 to avoid much needless work if the image is too large.
17488 (tiff_load): Treat overly large images as if
17489 x_create_x_image_and_pixmap failed, not as malloc failures.
17490 (gs_load): Use x_check_image_size.
17492 * gtkutil.c: Omit integer casts.
17493 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17494 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17496 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17498 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17499 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17500 would wrongly return t on a 64-bit host.
17502 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17503 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17504 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17505 and therefore cause GCC to emit a bogus diagnostic in some cases.
17507 * image.c: Integer signedness and overflow and related fixes.
17508 This is not an exhaustive set of fixes, but it's time to
17509 record what I've got.
17510 (lookup_pixel_color, check_image_size): Remove redundant decls.
17511 (check_image_size): Don't assume that arbitrary EMACS_INT values
17512 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17513 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17514 (tiff_load, imagemagick_load_image):
17515 Check for overflow in size calculations.
17516 (x_create_x_image_and_pixmap): Remove unnecessary test for
17517 xmalloc returning NULL; that can't happen.
17518 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17519 (xpm_color_bucket): Use better integer hashing function.
17520 (xpm_cache_color): Don't possibly over-allocate memory.
17521 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17522 (gif_memory_source):
17523 Use ptrdiff_t, not int or size_t, to record sizes.
17524 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17525 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17526 either works, as we prefer signed integers.
17527 (tiff_read_from_memory, tiff_write_from_memory):
17528 Return tsize_t, not size_t, since that's what the TIFF API wants.
17529 (tiff_read_from_memory): Don't fail simply because the read would
17530 go past EOF; instead, return a short read.
17531 (tiff_load): Omit no-longer-needed casts.
17532 (Fimagemagick_types): Don't assume size fits into 'int'.
17534 Improve hashing quality when configured --with-wide-int.
17535 * fns.c (hash_string): New function, taken from sxhash_string.
17536 Do not discard information about ASCII character case; this
17537 discarding is no longer needed.
17538 (sxhash-string): Use it. Change sig to match it. Caller changed.
17539 * lisp.h: Declare it.
17540 * lread.c (hash_string): Remove, since we now use fns.c's version.
17541 The fns.c version returns a wider integer if --with-wide-int is
17542 specified, so this should help the quality of the hashing a bit.
17544 * emacs.c: Integer overflow minor fix.
17545 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17546 Define only if GNU_LINUX.
17547 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17549 * dispnew.c: Integer signedness and overflow fixes.
17550 Remove unnecessary forward decls, that were a maintenance hassle.
17551 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17553 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17554 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17555 (prepare_desired_row, line_draw_cost):
17556 Use int, not unsigned, where either works.
17557 (save_current_matrix, restore_current_matrix):
17558 Use ptrdiff_t, not size_t, where either works.
17559 (init_display): Check for overflow more accurately, and without
17560 relying on undefined behavior.
17562 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17563 Remove, replacing with the new symbols in lisp.h. All uses changed.
17564 * fileio.c (make_temp_name):
17565 * filelock.c (lock_file_1, lock_file):
17566 * xdisp.c (message_dolog):
17567 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17568 Use pMd etc. instead.
17569 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17570 replacing the pWIDE etc. symbols removed from editfns.c.
17572 * keyboard.h (num_input_events): Now uintmax_t.
17573 This is (very slightly) less likely to mess up due to wraparound.
17576 * buffer.c: Integer signedness fixes.
17577 (alloc_buffer_text, enlarge_buffer_text):
17578 Use ptrdiff_t rather than size_t when either will do, as we prefer
17581 * alloc.c: Integer signedness and overflow fixes.
17582 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17583 (__malloc_size_t): Default to size_t, not to int.
17584 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17585 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17586 Prefer ptrdiff_t to size_t when either would do, as we prefer
17588 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17589 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17590 Now const. Initialize with values that are in range even if char
17592 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17593 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17594 These functions do the right thing with sizes > 2**32.
17595 (check_depth): Now ptrdiff_t, not int.
17596 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17597 Adjust to new way of storing sizes. Check for size overflow bugs
17599 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17600 slightly wrong anyway, as it missed one instance of
17601 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17602 (refill_memory_reserve): Omit needless cast to size_t.
17603 (mark_object_loop_halt): Mark as externally visible.
17605 * xselect.c: Integer signedness and overflow fixes.
17606 (Fx_register_dnd_atom, x_handle_dnd_message):
17607 Use ptrdiff_t, not size_t, since we prefer signed.
17608 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17609 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17610 x_dnd_atoms_size and x_dnd_atoms_length.
17612 * doprnt.c: Prefer signed to unsigned when either works.
17614 * doprnt.c (doprnt):
17616 * xdisp.c (vmessage):
17617 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17618 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17619 prefer signed arithmetic to avoid comparison confusion.
17620 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17621 but is a bit tricky.
17623 Assume freestanding C89 headers, string.h, stdlib.h.
17624 * data.c, doprnt.c, floatfns.c, print.c:
17625 Include float.h unconditionally.
17626 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17627 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17628 * regex.c: Likewise for stddef.h, string.h.
17629 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17630 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17631 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17632 (STDC_HEADERS): Remove obsolete defines.
17633 * sysdep.c: Include limits.h unconditionally.
17635 Assume support for memcmp, memcpy, memmove, memset.
17636 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17637 * regex.c (memcmp, memcpy):
17638 Remove; we assume C89 now.
17640 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17641 (__malloc_safe_bcopy): Remove; no longer needed.
17643 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17644 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17645 well either way, and we prefer signed to unsigned.
17647 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17649 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17650 closes the connection while we're reading (bug#9182).
17652 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17654 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17655 are specified (Bug#9168).
17657 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17659 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17660 Found by GCC static checking and --with-wide-int on a 32-bit host.
17662 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17664 * xdisp.c (compute_display_string_pos): Fix logic of caching
17665 previous display string position. Initialize cached_prev_pos to
17666 -1. Fixes slow-down at the beginning of a buffer.
17668 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17670 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17671 for attrs[LFACE_FONTSET_INDEX].
17673 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17675 * xml.c (parse_region): Remove unused local
17676 that was recently introduced.
17678 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17680 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17681 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17683 * xdisp.c (move_it_in_display_line_to): Record the best matching
17684 position for TO_CHARPOS while scanning the line, and restore it on
17685 exit if none of the characters scanned was an exact match.
17686 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17687 when exact match is impossible due to invisible text, and the
17688 lines are truncated.
17690 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17692 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17695 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17697 Fix a significant slow-down of cursor motion with C-n, C-p,
17698 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17699 auto-repeat under bidi redisplay in fontified buffers.
17700 * xdisp.c (compute_stop_pos_backwards): New function.
17701 (next_element_from_buffer): Call compute_stop_pos_backwards to
17702 find a suitable prev_stop when we find ourselves before
17704 (reseat): Don't look for prev_stop, as that could mean a very long
17706 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17707 <cached_disp_overlay_modiff>: Cache for last found display string
17709 (compute_display_string_pos): Return the cached position if asked
17710 about the same buffer in the same area of character positions, and
17711 the buffer wasn't changed since the time the display string
17712 position was cached.
17714 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17716 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17717 is an integer, which is important for empty lines. (Bug#9149)
17719 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17721 * frame.c (Fmodify_frame_parameters): In tty case, update the
17722 default face if necessary (Bug#4238).
17724 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17726 * editfns.c (Fstring_to_char): No need to explain what a character
17727 is in the docstring (Bug#6576).
17729 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17731 * xml.c (parse_region): Make sure we always return a tree.
17733 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17735 * xml.c (parse_region): If a document contains only comments,
17738 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17740 * xml.c (make_dom): Return comments, too.
17742 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17745 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17746 and the surrounding thread.
17747 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17748 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17749 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17751 * s/openbsd.h (BROKEN_SIGIO): Define.
17752 * unexelf.c (unexec) [__OpenBSD__]:
17753 Don't update the .mdebug section of the Alpha COFF symbol table.
17755 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17757 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17760 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17762 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17763 This fixes some race conditions on the permissions of any newly
17766 * alloc.c (valid_pointer_p): Use pipe, not open.
17767 This fixes some permissions issues when debugging.
17769 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17770 If fchown fails to set both uid and gid, try to set just gid,
17771 as that is sometimes allowed. Adjust the file's mode to eliminate
17772 setuid or setgid bits that are inappropriate if fchown fails.
17774 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17776 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17777 to compare Lisp_Objects.
17778 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17779 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17780 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17782 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>

17792 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17793 This works around a problem with the previous change to Fcopy_file.
17794 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17795 and without this change, GCC might complain about discarding
17796 fchown's return value.
17798 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17800 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17802 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>

17823 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17825 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17826 quotes the next character, and doesn't affect other longer
17827 sequences (bug#8935).
17829 * lread.c (syms_of_lread): Clarify that is isn't only
17830 `eval-buffer' and `eval-defun' that's affected by

17841 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17842 (elsz): Now a signed constant, not a size_t var. We prefer signed
17843 types to unsigned, to avoid integer comparison confusion. Without
17844 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17845 "cannot optimize loop, the loop counter may overflow", a symptom
17847 * indent.c (Fvertical_motion): Mark locals as initialized.
17848 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17850 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

17877 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17878 original value of -1 will not work with bidi.)
17879 (compute_display_string_pos): First arg is now struct

17894 the iterator is before prev_stop.
17895 (init_iterator): Initialize bidi_p from the default value of

17937 iterator by calling bidi_pop_it same number of times.
17938 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17939 and we are bidi-iterating, don't decrement the iterator position;
17940 instead, set the first_elt flag in the bidi iterator, to produce
17942 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17943 (push_display_prop): xassert that we are iterating a buffer.

17947 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17948 correctly. Don't assume unibyte strings are not bidi-reordered.

18372 (clone_per_buffer_values): Don't assume that

18374 This isn't true in general, and it's particularly not true
18375 if Emacs is configured with --with-wide-int.
18376 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
18377 New macros, used in the buffer.c change.

18413 Random fixes. E.g., (random) never returned negative values.
18414 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18415 subseconds part to the entropy, as that's a bit more random.
18416 Prefer signed to unsigned, since the signedness doesn't matter and
18417 in general we prefer signed. When given a limit, use a
18418 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18419 latter isn't right if USE_2_TAGS_FOR_INTS.
18420 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18421 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18425 * textprop.c (text_property_stickiness):
18426 Obey Vtext_property_default_nonsticky.

18433 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18434 This is more efficient than Ffile_directory_p and avoids a minor race.
18436 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18438 * buffer.c (Foverlay_put): Say what the return value is
18441 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18442 is a directory before asking whether to use the file name
18444 (barf_or_query_if_file_exists): Make the "File is a directory"
18445 error be more correct.
18447 * fns.c (Frequire): Remove the mention of the .gz files, since
18448 that's installation-specific, but keep the mention of

18453 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

18461 Qgnutls_bootprop_verify_error (which is no longer used).
18463 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18464 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18465 Also (re)move comments that are misplaced or no longer relevant.

18492 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
18494 * lread.c (syms_of_lread): Mention single symbols defined by
18495 `defvar' or `defconst' (bug#7154).
18497 * fns.c (Frequire): Mention .el.gz files (bug#7314).
18498 (Frequire): Mention get-load-suffixes.

18566 * eval.c (struct backtrace): Simplify and port the data structure.
18567 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18568 signed bit field, as this assumption is not portable and it makes
18569 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18570 "char debug_on_exit : 1" as this is not portable either; instead,
18571 use the portable "unsigned int debug_on_exit : 1". Remove unused
18572 member evalargs. Remove obsolete comments about cc bombing out.
18574 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18662 * process.c (wait_reading_process_output): Bypass select if
18663 waiting for a cell while ignoring keyboard input, and input is
18664 pending. Suggested by Jan Djärv (Bug#8869).
18666 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
18668 Use gnulib's dup2 module instead of rolling our own.
18669 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
18671 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18673 * dispnew.c (scrolling_window): Before scrolling, turn off a

18736 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
18738 Integer and buffer overflow fixes (Bug#8873).
18740 * print.c (printchar, strout): Check for string overflow.
18741 (PRINTPREPARE, printchar, strout):
18742 Don't set size unless allocation succeeds.
18744 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18745 for sizes. Check for string overflow more accurately.
18746 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
18748 * macros.c: Integer and buffer overflow fixes.
18749 * keyboard.h (struct keyboard.kbd_macro_bufsize):
18750 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

18753 Check for size-calculation overflow.
18754 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
18756 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
18758 * lread.c: Integer overflow fixes.
18759 (read_integer): Radix is now EMACS_INT, not int,
18760 to improve quality of diagnostics for out-of-range radices.
18761 Calculate buffer size correctly for out-of-range radices.
18762 (read1): Check for integer overflow in radices, and in
18763 read-circle numbers.
18764 (read_escape): Avoid int overflow.
18765 (Fload, openp, read_buffer_size, read1)
18766 (substitute_object_recurse, read_vector, read_list, map_obarray):
18767 Use ptrdiff_t, not int, for sizes.

18782 2011-06-22 Leo Liu <sdl.web@gmail.com>
18784 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
18785 Move to minibuffer.el.
18787 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18789 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18790 The following patches are for when GLYPH_DEBUG && !XASSERT.
18791 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18792 * dispnew.c (flush_stdout):
18793 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18794 Mark as externally visible.
18795 * dispnew.c (check_window_matrix_pointers): Now static.
18796 * dispnew.c (window_to_frame_vpos):
18797 * xfns.c (unwind_create_frame):
18798 * xterm.c (x_check_font): Remove unused local.
18799 * scroll.c (CHECK_BOUNDS):
18800 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18801 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18802 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18803 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18804 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18806 (debug_method_add): Use va_list and vsprintf rather than relying
18807 on undefined behavior with wrong number of arguments.
18808 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18809 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18810 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18811 since we're not interested in debugging glyphs with old libraries.
18812 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18813 GCC 4.6.0's static checking.
18815 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18817 Integer overflow and signedness fixes (Bug#8873).

18828 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
18829 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
18831 * xfaces.c (load_pixmap):

18833 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18834 (.bitmaps_last, struct x_output.icon_bitmap):
18835 Use ptrdiff_t, not int, for bitmap indexes.
18836 (x_allocate_bitmap_record): Check for size overflow.
18837 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18839 Use ptrdiff_t, not int, for overlay counts.
18840 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18841 * editfns.c (overlays_around, get_pos_property):
18842 * textprop.c (get_char_property_and_overlay):
18843 * xdisp.c (next_overlay_change, note_mouse_highlight):
18844 * xfaces.c (face_at_buffer_position):
18845 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18846 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18847 (Fnext_overlay_change, Fprevious_overlay_change)
18848 (mouse_face_overlay_overlaps, Foverlays_in):
18849 Use ptrdiff_t, not int, for sizes.
18850 (overlays_at, overlays_in): Check for size-calculation overflow.
18852 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18854 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18855 (x_session_initialize): Do not assume string length fits in int.
18857 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18858 This is unlikely, but can occur if DPI is outlandish.
18860 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18861 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18863 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18864 * xrdb.c (magic_file_p, search_magic_path):
18865 Omit last arg SUFFIX; it was always 0. All callers changed.
18866 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18868 * xfont.c (xfont_match): Avoid need for strlen.
18870 * xfns.c: Don't assume strlen fits in int.

18873 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18874 not unsigned long, as we prefer signed integers. All callers changed.
18875 Detect integer overflow in repeat count.
18876 (message_dolog): Don't assume print length fits in 39 bytes.
18877 (display_mode_element): Don't assume strlen fits in int.
18879 * termcap.c: Don't assume sizes fit in int and never overflow.
18880 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18881 (gobble_line): Check for size-calculation overflow.
18883 * minibuf.c (Fread_buffer):
18884 * lread.c (intern, intern_c_string):

18891 * font.c: Don't assume string length fits in int.
18892 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
18893 Use ptrdiff_t, not int.
18894 (font_intern_prop): Don't assume string length fits in int.
18895 Don't assume integer property fits in fixnum.
18896 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18898 * filelock.c: Fix some buffer overrun and integer overflow issues.
18899 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18900 Reformulate so as not to need the command string.
18901 Invoke gzip -cd rather than gunzip, as it's more portable.
18902 (lock_info_type, lock_file_1, lock_file):
18903 Don't assume pid_t and time_t fit in unsigned long.
18904 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18905 (current_lock_owner): Prefer signed type for sizes.
18906 Use memcpy, not strncpy, where memcpy is what is really wanted.
18907 Don't assume (via atoi) that time_t and pid_t fit in int.
18908 Check for time_t and/or pid_t out of range, e.g., via a network share.
18909 Don't alloca where an auto var works fine.
18911 * fileio.c: Fix some integer overflow issues.
18912 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18913 Don't assume string length fits in int.
18914 (directory_file_name): Don't assume string length fits in long.
18915 (make_temp_name): Don't assume pid fits in int, or that its print
18916 length is less than 20.
18918 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18920 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18922 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18924 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18925 We prefer signed integers, even for size calculations.
18927 * emacs.c: Don't assume string length fits in 'int'.
18928 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18929 (main): Don't invoke strlen when not needed.
18931 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

18934 * callproc.c (getenv_internal_1, getenv_internal)
18935 (Fgetenv_internal):
18936 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18938 * lread.c (invalid_syntax): Omit length argument.
18939 All uses changed. This doesn't fix a bug, but it simplifies the
18940 code away from its former Hollerith-constant appearance, and it's
18941 one less 'int' to worry about when looking at integer-overflow issues.
18942 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18944 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18945 This didn't break anything, but it didn't help either.
18946 It's confusing to put a bogus integer in a place where the actual
18947 value does not matter.
18948 (LIST_END_P): Remove unused macro and its bogus comment.
18949 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18951 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18952 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18954 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18955 We prefer signed types, and the value cannot exceed the EMACS_INT
18956 range anyway (because otherwise the length would not be representable).
18957 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18958 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18959 This avoids a GCC warning when WIDE_EMACS_INT.
18961 * indent.c (sane_tab_width): New function.
18962 (current_column, scan_for_column, Findent_to, position_indentation)
18963 (compute_motion): Use it. This is just for clarity.
18964 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18966 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

18969 * composite.c (composition_gstring_put_cache):
18970 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18972 * editfns.c, insdel.c:
18973 Omit unnecessary forward decls, to simplify future changes.
18975 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18977 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18979 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18980 Use much-faster test for byte-length change.
18981 Don't assume string byte-length fits in 'int'.
18982 Check that character arg fits in 'int'.
18983 (mapcar1): Declare byte as byte, for clarity.
18985 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18987 * fns.c (concat): Catch string overflow earlier.
18988 Do not rely on integer wraparound.
18990 * dispextern.h (struct it.overlay_strings_charpos)
18991 (struct it.selective): Now EMACS_INT, not int.
18992 * xdisp.c (forward_to_next_line_start)
18993 (back_to_previous_visible_line_start)
18994 (reseat_at_next_visible_line_start, next_element_from_buffer):
18995 Don't arbitrarily truncate the value of 'selective' to int.
18997 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18999 * composite.c: Don't truncate sizes to 'int'.
19000 (composition_gstring_p, composition_reseat_it)
19001 (composition_adjust_point): Use EMACS_INT, not int.
19002 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19003 not EMACS_UINT, for indexes.
19005 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19007 * buffer.c: Include <verify.h>.
19008 (struct sortvec.priority, struct sortstr.priority):
19009 Now EMACS_INT, not int.
19010 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19011 (struct sortstr.size, record_overlay_string)
19012 (struct sortstrlist.size, struct sortlist.used):
19013 Don't truncate size to int.
19014 (record_overlay_string): Check for size-calculation overflow.
19015 (init_buffer_once): Check at compile-time, not run-time.
19017 2011-06-22 Jim Meyering <meyering@redhat.com>
19019 Don't leak an XBM-image-sized buffer
19020 * image.c (xbm_load): Free the image buffer after using it.
19022 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19025 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19026 that Sun C diagnosed.
19027 * fns.c (secure_hash): Fix pointer signedness issue.
19028 * intervals.c (static_offset_intervals): New function.
19029 (offset_intervals): Use it.
19031 2011-06-21 Leo Liu <sdl.web@gmail.com>
19034 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19037 * fns.c (secure_hash): Rename from crypto_hash_function and change
19038 the first arg to accept symbols.
19039 (Fsecure_hash): New primitive.
19040 (syms_of_fns): New symbols.
19042 2011-06-20 Deniz Dogan <deniz@dogan.se>
19044 * process.c (Fset_process_buffer): Clarify return value in
19047 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19049 * dispnew.c (add_window_display_history): Use BVAR.
19051 * xdisp.c (debug_method_add): Use BVAR.
19052 (check_window_end, dump_glyph_matrix, dump_glyph)
19053 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19055 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19058 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19059 check till after the cache is created in init_frame_faces.
19061 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19063 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19065 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19067 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19068 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19069 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19071 Improve buffer-overflow checking (Bug#8873).
19072 * fileio.c (Finsert_file_contents):
19073 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19074 Remove the old (too-loose) buffer overflow checks.
19075 They weren't needed, since make_gap checks for buffer overflow.
19076 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19077 The old code merely checked for Emacs fixnum overflow, and relied
19078 on undefined (wraparound) behavior. The new code avoids undefined
19079 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19081 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19082 Tune. Don't use wider integers than needed. Don't use alloca.
19083 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19085 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19087 * insdel.c, lisp.h (buffer_overflow): New function.
19088 (insert_from_buffer_1, replace_range, replace_range_2):
19089 * insdel.c (make_gap_larger):
19090 * editfns.c (Finsert_char):
19091 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19093 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19095 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19097 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19099 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19100 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19102 * fileio.c: Don't assume EMACS_INT fits in off_t.
19103 (emacs_lseek): New static function.
19104 (Finsert_file_contents, Fwrite_region): Use it.
19105 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19107 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19109 * fns.c: Don't overflow int when computing a list length.
19110 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19111 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19112 truncation on 64-bit hosts. Check for QUIT every
19113 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19114 faster and is responsive enough.
19115 (Flength): Report an error instead of overflowing an integer.
19116 (Fsafe_length): Return a float if the value is not representable
19117 as a fixnum. This shouldn't happen except in contrived situations.
19118 (Fnthcdr, Fsort): Don't assume list length fits in int.
19119 (Fcopy_sequence): Don't assume vector length fits in int.
19121 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19122 (header_size, word_size): New constants.
19123 (allocate_vectorlike): Don't check size overflow here.
19124 (allocate_vector): Check it here instead, since this is the only
19125 caller of allocate_vectorlike that could cause overflow.
19126 Check that the new vector's length is representable as a fixnum.
19128 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19129 The previous code was bogus. For example, next_almost_prime (32)
19130 returned 39, which is undesirable as it is a multiple of 3; and
19131 next_almost_prime (24) returned 25, which is a multiple of 5 so
19132 why was the code bothering to check for multiples of 7?
19134 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19136 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19138 Variadic C functions now count arguments with ptrdiff_t.
19139 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19140 Back then I didn't know that the Emacs coding style prefers signed int.
19141 Also, in the meantime I found a few more instances where arguments
19142 were being counted with int, which may truncate counts on 64-bit
19143 machines, or EMACS_INT, which may be unnecessarily wide.
19144 * lisp.h (struct Lisp_Subr.function.aMANY)
19145 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19146 Arg counts are now ptrdiff_t, not size_t.
19147 All variadic functions and their callers changed accordingly.
19148 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19149 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19150 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19151 * callint.c (Fcall_interactively): Check arg count for overflow,
19152 to avoid potential buffer overrun. Use signed char, not 'int',
19153 for 'varies' array, so that we needn't bother to check its size
19154 calculation for overflow.
19155 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19156 * eval.c (apply_lambda):
19157 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19158 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19159 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19161 * callint.c (Fcall_interactively): Don't use index var as event count.
19163 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19164 * mem-limits.h (SIZE): Remove; no longer used.
19166 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19168 Remove unnecessary casts.
19169 * xterm.c (x_term_init):
19170 * xfns.c (x_set_border_pixel):
19171 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19172 These aren't needed now that we assume ANSI C.
19174 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19175 It's more likely to cause problems (due to unsigned overflow)
19178 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19180 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19182 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19184 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19186 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19188 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19190 GLYPH_CODE_FACE returns EMACS_INT, not int.
19191 * dispextern.h (merge_faces):
19192 * xfaces.c (merge_faces):
19193 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19194 Don't assume EMACS_INT fits in int.
19196 * character.h (CHAR_VALID_P): Remove unused parameter.
19197 * fontset.c, lisp.h, xdisp.c: All uses changed.
19199 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19201 * fns.c (concat): Minor tuning based on overflow analysis.
19202 This doesn't fix any bugs. Use int to hold character, instead
19203 of constantly refetching from Emacs object. Use XFASTINT, not
19204 XINT, for value known to be a character. Don't bother comparing
19205 a single byte to 0400, as it's always less.
19207 * floatfns.c (Fexpt):
19208 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19210 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19213 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19215 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19216 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19217 incorrectly succeed when S was a string, because 4294967386 was
19218 truncated before it was used.
19220 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19221 Otherwise, an out-of-range integer could cause undefined behavior
19224 * composite.c: Use int, not EMACS_INT, for characters.
19225 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19226 EMACS_INT, for values that are known to be in character range.
19227 This doesn't fix any bugs but is the usual style inside Emacs and
19228 may generate better code on 32-bit machines.
19230 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19231 This is for reasons similar to the recent CHAR_STRING fix.
19232 * charset.c (Fencode_char): Check that character arg is actually
19233 a character. Pass an int to ENCODE_CHAR.
19234 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19235 wider than 'int', as a compile-time check to prevent future regressions
19238 * character.c (char_string): Remove unnecessary casts.
19240 Make sure a 64-bit char is never passed to CHAR_STRING.
19241 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19242 by silently ignoring the top 32 bits, allowing some values
19243 that were far too large to be valid characters.
19244 * character.h: Include <verify.h>.
19245 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19246 arguments are no wider than unsigned, as a compile-time check
19247 to prevent future regressions in this area.
19249 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19250 (Fsubst_char_in_region):
19252 * xdisp.c (decode_mode_spec_coding):
19253 Adjust to CHAR_STRING's new requirement.
19254 * editfns.c (Finsert_char, Fsubst_char_in_region):
19255 * fns.c (concat): Check that character args are actually
19256 characters. Without this test, these functions did the wrong
19257 thing with wildly out-of-range values on 64-bit hosts.
19259 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19260 These casts should not be needed on 32-bit hosts, either.
19261 * keyboard.c (read_char):
19262 * lread.c (Fload): Remove casts to unsigned.
19264 * lisp.h (UNSIGNED_CMP): New macro.
19265 This fixes comparison bugs on 64-bit hosts.
19266 (ASCII_CHAR_P): Use it.
19267 * casefiddle.c (casify_object):
19268 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19269 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19270 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19271 * dispextern.h (FACE_FROM_ID):
19272 * keyboard.c (read_char): Use UNSIGNED_CMP.
19274 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19275 not to EMACS_INT, to avoid GCC warning.
19277 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19279 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19280 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19281 isn't needed on 32-bit machines.
19283 * buffer.c (Fgenerate_new_buffer_name):
19284 Use EMACS_INT for count, not int.
19285 (advance_to_char_boundary): Return EMACS_INT, not int.
19287 * data.c (Qcompiled_function): Now static.
19289 * window.c (window_body_lines): Now static.
19291 * image.c (gif_load): Rename local to avoid shadowing.
19293 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19294 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19295 * alloc.c (make_save_value): Integer argument is now of type
19296 ptrdiff_t, not int.
19297 (mark_object): Use ptrdiff_t, not int.
19298 * lisp.h (pD): New macro.
19299 * print.c (print_object): Use it.
19301 * alloc.c: Use EMACS_INT, not int, to count objects.
19302 (total_conses, total_markers, total_symbols, total_vector_size)
19303 (total_free_conses, total_free_markers, total_free_symbols)
19304 (total_free_floats, total_floats, total_free_intervals)
19305 (total_intervals, total_strings, total_free_strings):
19306 Now EMACS_INT, not int. All uses changed.
19307 (Fgarbage_collect): Compute overall total using a double, so that
19308 integer overflow is less likely to be a problem. Check for overflow
19309 when converting back to an integer.
19310 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19311 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19312 These were 'int' variables that could overflow on 64-bit hosts;
19313 they were never used, so remove them instead of repairing them.
19314 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19315 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19316 Previously, this ceilinged at INT_MAX, but that doesn't work on
19318 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19320 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19321 (allocate_vectorlike): Check for ptrdiff_t overflow.
19322 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19323 when a (possibly-narrower) signed value would do just as well.
19324 We prefer using signed arithmetic, to avoid comparison confusion.
19326 * alloc.c: Catch some string size overflows that we were missing.
19327 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19328 for convenience in STRING_BYTES_MAX.
19329 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19330 The definition here is exact; the one in lisp.h was approximate.
19331 (allocate_string_data): Check for string overflow. This catches
19332 some instances we weren't catching before. Also, it catches
19333 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19334 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19335 and ptrdiff_t and EMACS_INT are both 64 bits.
19337 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19338 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19339 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19341 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19343 * alloc.c (Fmake_string): Check for out-of-range init.
19345 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19347 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
19349 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
19351 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
19352 xg_get_default_scrollbar_width.
19354 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
19355 (int_gtk_range_get_value): Move to the scroll bar part of the file.
19356 (style_changed_cb): Call update_theme_scrollbar_width and call
19357 x_set_scroll_bar_default_width and xg_frame_set_char_size for
19358 all frames (Bug#8505).
19359 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
19360 Call gtk_window_set_resizable if HAVE_GTK3.
19361 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
19362 and height if HAVE_GTK3 (Bug#8505).
19363 (scroll_bar_width_for_theme): New variable.
19364 (update_theme_scrollbar_width): New function.
19365 (xg_get_default_scrollbar_width): Move code to
19366 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
19367 (xg_initialize): Call update_theme_scrollbar_width.
19369 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
19371 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
19373 2011-06-12 Martin Rudalics <rudalics@gmx.at>
19375 * frame.c (make_frame): Call other_buffer_safely instead of
19378 * window.c (temp_output_buffer_show): Call display_buffer with
19379 second argument Vtemp_buffer_show_specifiers and reset latter
19380 immediately after the call.
19381 (Vtemp_buffer_show_specifiers): New variable.
19382 (auto_window_vscroll_p, next_screen_context_lines)
19383 (Vscroll_preserve_screen_position): Remove leading asterisks from
19386 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
19388 Fix minor problems found by GCC 4.6.0 static checking.
19389 * buffer.c (Qclone_number): Remove for now, as it's unused.
19390 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
19391 (record_buffer): Remove unused local.
19392 * frame.c (other_visible_frames, frame_buffer_list): Now static.
19393 (set_frame_buffer_list): Remove; unused.
19394 * frame.h (other_visible_frames): Remove decl.
19395 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
19396 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
19397 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
19399 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
19400 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
19401 Define only if HAVE_GPM.
19402 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
19403 (update_hints_inhibit): Remove; never set. All uses removed.
19404 * widgetprv.h (emacsFrameClassRec): Remove decl.
19405 * window.c (delete_deletable_window): Now returns void, since it
19406 wasn't returning anything.
19407 (compare_window_configurations): Remove unused locals.
19408 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
19409 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
19410 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
19411 the same widths as pointers. This follows up on the 2011-05-06 patch.
19412 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
19413 * xterm.h: Likewise.

19419 (LISP_H): Add lib/intprops.h.
19421 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
19423 * image.c (gif_load): Add animation frame delay to the metadata.
19424 (syms_of_image): Use DEFSYM. New symbol `delay'.
19426 2011-06-11 Martin Rudalics <rudalics@gmx.at>
19428 * window.c (delete_deletable_window): Re-add.
19429 (Fset_window_configuration): Rewrite to handle dead buffers and
19430 consequently deletable windows.
19431 (window_tree, Fwindow_tree): Remove. Supply functionality in
19433 (compare_window_configurations): Simplify code.
19435 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
19437 * image.c (imagemagick_load_image): Fix type mismatch.
19438 (Fimagemagick_types): Likewise.
19440 * window.h (replace_buffer_in_windows): Declare.
19442 2011-06-11 Martin Rudalics <rudalics@gmx.at>
19444 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
19445 Qclone_number. Remove external declaration of Qdelete_window.
19446 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
19448 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
19449 Run Qbuffer_list_update_hook if allowed.
19450 (Fother_buffer): Rewrite doc-string. Major rewrite for new
19451 buffer list implementation.
19452 (other_buffer_safely): New function.
19453 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
19454 calls to replace_buffer_in_windows and
19455 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
19457 (record_buffer): Inhibit quitting and rewrite using quittable
19458 functions. Run Qbuffer_list_update_hook if allowed.
19459 (Frecord_buffer, Funrecord_buffer): New functions.
19460 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
19461 Move switch-to-buffer to window.el.
19462 (bury-buffer): Move to window.el.
19463 (Vbuffer_list_update_hook): New variable.
19465 * lisp.h (other_buffer_safely): Add prototype in buffer.c
19468 * window.h (resize_frame_windows): Move up in code.
19469 (Fwindow_frame): Remove EXFUN.
19470 (replace_buffer_in_all_windows): Remove prototype.
19471 (replace_buffer_in_windows_safely): Add prototype.
19473 * window.c: Declare Qdelete_window static again. Move down
19474 declaration of select_count.
19475 (Fnext_window, Fprevious_window): Rewrite doc-strings.
19476 (Fother_window): Move to window.el.
19477 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
19478 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
19479 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
19481 (replace_buffer_in_windows): Implement by calling
19482 Qreplace_buffer_in_windows.
19483 (replace_buffer_in_all_windows): Remove with some functionality
19484 moved into replace_buffer_in_windows_safely.
19485 (replace_buffer_in_windows_safely): New function.
19486 (select_window_norecord, select_frame_norecord): Move in front
19487 of run_window_configuration_change_hook. Remove now obsolete
19489 (Fset_window_buffer): Rewrite doc-string.
19490 Call Qrecord_window_buffer.
19491 (keys_of_window): Move binding for other-window to window.el.
19493 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
19495 * dispextern.h (struct image): Replace data member, whose int_val
19496 and ptr_val fields were not used by anything, with a single
19499 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
19500 (gif_clear_image, gif_load, imagemagick_load_image)
19501 (gs_clear_image, gs_load): Callers changed.

19976 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19977 All callers changed. (Bug#8762)
19979 * gnutls.c: Use Emacs's memory allocators.
19980 Without this change, the gnutls library would invoke malloc etc.
19981 directly, which causes problems on non-SYNC_INPUT hosts, and which
19982 runs afoul of improving memory_full behavior. (Bug#8761)
19983 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19984 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19985 xfree instead of the default malloc, realloc, free.
19986 (Fgnutls_boot): No need to check for memory allocation failure,
19987 since xmalloc does that for us.
19989 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19990 * category.c (hash_get_category_set):
19991 * ccl.c (ccl_driver):
19992 * charset.c (Fdefine_charset_internal):
19993 * charset.h (struct charset.hash_index):

19995 (composition_gstring_put_cache):
19996 * composite.h (struct composition.hash_index):
19997 * dispextern.h (struct image.hash):
19998 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
19999 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)

20003 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
20004 (Fsxhash, Fgethash, Fputhash, Fmaphash):
20005 * image.c (make_image, search_image_cache, lookup_image)
20006 (xpm_put_color_table_h):
20007 * lisp.h (struct Lisp_Hash_Table):
20008 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
20009 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
20010 for hashes and hash indexes, instead of 'unsigned' and 'int'.
20011 * alloc.c (allocate_vectorlike):
20012 Check for overflow in vector size calculations.
20013 * ccl.c (ccl_driver):
20014 Check for overflow when converting EMACS_INT to int.
20015 * fns.c, image.c: Remove unnecessary static decls that would otherwise
20016 need to be updated by these changes.
20017 * fns.c (make_hash_table, maybe_resize_hash_table):
20018 Check for integer overflow with large hash tables.
20019 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20020 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20021 (SXHASH_REDUCE): New macro.
20022 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20023 Use it instead of discarding useful hash info with large hash values.
20024 (sxhash_float): New function.
20025 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20026 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20027 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20028 Rewrite to use FIXNUM_BITS, as this simplifies things.
20029 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20030 Adjust signatures to match updated version of code.
20031 (consing_since_gc): Now EMACS_INT, since a single hash table can
20032 use more than INT_MAX bytes.
20034 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
20036 Make it possible to build with GCC-4.6+ -O2 -flto.
20038 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
20040 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
20042 * minibuf.c (get_minibuffer, read_minibuf_unwind):
20043 Call minibuffer-inactive-mode.
20045 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
20047 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
20048 Update dependencies.
20050 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20052 * data.c (init_data): Remove code for UTS, this system is not
20055 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20057 Don't force ./temacs to start in terminal mode.
20059 * frame.c (make_initial_frame): Initialize faces in all cases, not
20060 only when CANNOT_DUMP is defined.
20061 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
20063 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20065 * dispnew.c (add_window_display_history): Use const for the string
20066 pointer. Remove declaration, not needed.
20068 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20070 Use 'inline', not 'INLINE'.
20071 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20072 * alloc.c, fontset.c (INLINE): Remove.
20073 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20074 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20075 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20076 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20077 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20079 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20081 Make it possible to run ./temacs.
20083 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20084 syms_of_callproc does the same thing. Remove test for
20085 "initialized", do it in the caller.
20086 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20088 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20090 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20091 (read_minibuf): Use get_minibuffer.
20092 (syms_of_minibuf): Use DEFSYM.
20093 (Qmetadata): New var.
20094 * data.c (Qbuffer): Don't make it static.
20095 (syms_of_data): Use DEFSYM.
20097 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20099 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20100 (CCL_CODE_MIN): New macro.
20102 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20104 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20106 * eval.c (Qdebug): Now static.
20107 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20108 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20109 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20111 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20113 * image.c: Various fixes to ImageMagick code comments.
20114 (Fimagemagick_types): Doc fix.
20116 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20118 Minor fixes prompted by GCC 4.6.0 warnings.
20120 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20122 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20123 (x_clipboard_manager_save_all): Move extern decl to ...
20124 * xterm.h: ... here, so that it can be checked for consistency.
20126 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20128 * xselect.c (x_clipboard_manager_save_frame)
20129 (x_clipboard_manager_save_all): New functions.
20130 (Fx_clipboard_manager_save): Lisp function deleted.
20132 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20133 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20135 * xterm.h: Update prototype.
20137 2011-05-28 William Xu <william.xwl@gmail.com>
20139 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20140 exiting (Bug#8239).
20142 2011-05-28 Jim Meyering <meyering@redhat.com>
20144 Avoid a sign-extension bug in crypto_hash_function.
20145 * fns.c (to_uchar): Define.
20146 (crypto_hash_function): Use it to convert some newly-signed
20147 variables to unsigned, to avoid sign-extension bugs. For example,
20148 without this change, (md5 "truc") would evaluate to
20149 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20150 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20151 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20153 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20155 Integer overflow fixes.
20157 * dbusbind.c: Serial number integer overflow fixes.
20158 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20159 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20160 to hold a serial number that is too large for a fixnum.
20161 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20162 Check for serial numbers out of range. Decode any serial number
20163 that was so large that it became a float. (Bug#8722)
20165 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20166 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20167 Use XFASTINT rather than XUINT when numbers are nonnegative.
20168 (xd_append_arg, Fdbus_method_return_internal):
20169 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20170 arguments, check that Lisp number is nonnegative, rather than
20171 silently wrapping negative numbers around. (Bug#8722)
20172 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20175 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20177 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20179 ccl: Add integer overflow checks.
20180 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20181 (IN_INT_RANGE): New macros.
20182 (ccl_driver): Use them to check for integer overflow when
20183 decoding a CCL program. Many of the new checks are whether XINT (x)
20184 fits in int; it doesn't always, on 64-bit hosts. The new version
20185 doesn't catch all possible integer overflows, but it's an
20186 improvement. (Bug#8719)
20188 * alloc.c (make_event_array): Use XINT, not XUINT.
20189 There's no need for unsigned here.
20191 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20192 This follows up to the 2011-05-06 change that substituted uintptr_t
20193 for EMACS_INT. This case wasn't caught back then.
20195 Rework Fformat to avoid integer overflow issues.
20196 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20197 now (part of C89). Include <verify.h>.
20198 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20199 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20200 (Fformat): Avoid the prepass trying to compute sizes; it was only
20201 approximate and thus did not catch overflow reliably. Instead, walk
20202 through the format just once, formatting and computing sizes as we go,
20203 checking for integer overflow at every step, and allocating a larger
20204 buffer as needed. Keep track separately whether the format is
20205 multibyte. Keep only the most-recently calculated precision, rather
20206 than them all. Record whether each argument has been converted to
20207 string. Use EMACS_INT, not int, for byte and char and arg counts.
20208 Support field widths and precisions larger than INT_MAX. Avoid
20209 sprintf's undefined behavior with conversion specifications such as %#d
20210 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20211 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20212 formatting out-of-range floating point numbers with int
20213 formats. (Bug#8668)
20215 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20217 * data.c: Avoid integer truncation in expressions involving floats.
20218 * data.c: Include <intprops.h>.
20219 (arith_driver): When there's an integer overflow in an expression
20220 involving floating point, convert the integers to floating point
20221 so that the resulting value does not suffer from catastrophic
20222 integer truncation. For example, on a 64-bit host (* 4
20223 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20224 Do not rely on undefined behavior after integer overflow.
20226 merge count_size_as_multibyte, parse_str_to_multibyte
20227 * character.c, character.h (count_size_as_multibyte):
20228 Rename from parse_str_to_multibyte; all uses changed.
20229 Check for integer overflow.
20230 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20231 since it's now a duplicate of the other. This is more of
20232 a character than a buffer op, so better that it's in character.c.
20233 * fns.c, print.c: Adjust to above changes.
20235 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20237 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20239 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20241 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20242 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20243 (x_clipboard_manager_save): Now static.
20244 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20246 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20247 (crypto_hash_function): Now static.
20248 Fix pointer signedness problems. Avoid unnecessary initializations.
20250 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20252 * termhooks.h (Vselection_alist): Make it terminal-local.
20254 * terminal.c (create_terminal): Initialize it.
20256 * xselect.c: Support for clipboard managers.
20257 (Vselection_alist): Move to termhooks.h as terminal-local var.
20258 (LOCAL_SELECTION): New macro.
20259 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20260 (symbol_to_x_atom): Remove gratuitous arg.
20261 (x_handle_selection_request, lisp_data_to_selection_data)
20262 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20263 (x_own_selection, x_get_local_selection, x_convert_selection):
20264 New arg, specifying work frame. Use terminal-local Vselection_alist.
20265 (some_frame_on_display): Delete unused function.
20266 (Fx_own_selection_internal, Fx_get_selection_internal)
20267 (Fx_disown_selection_internal, Fx_selection_owner_p)
20268 (Fx_selection_exists_p): New optional frame arg.
20269 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20270 (x_handle_selection_clear): Don't treat other terminals with the
20271 same keyboard specially. Use the terminal-local Vselection_alist.
20272 (x_clear_frame_selections): Use Frun_hook_with_args.
20274 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20276 * xterm.h: Add support for those atoms.
20278 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20280 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20281 (converted_selections, conversion_fail_tag): New global variables.
20282 (x_selection_request_lisp_error): Free the above.
20283 (x_get_local_selection): Remove unnecessary code.
20284 (x_reply_selection_request): Args changed; handle arbitrary array
20285 of converted selections stored in converted_selections.
20286 Separate the XChangeProperty and SelectionNotify steps.
20287 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20288 (x_convert_selection): New function.
20289 (x_handle_selection_event): Simplify.
20290 (x_get_foreign_selection): Don't ignore incoming requests while
20291 waiting for an answer; this will fail when we implement
20292 SAVE_TARGETS, and seems unnecessary anyway.
20293 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20294 (Vx_sent_selection_functions): Doc fix.
20296 2011-05-26 Leo Liu <sdl.web@gmail.com>
20298 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20300 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20302 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20304 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20305 for fringe update if it has periodic bitmap.
20306 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20307 and fringe_bitmap_periodic_p.
20309 * fringe.c (get_fringe_bitmap_data): New function.
20310 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20311 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20312 row. Mark glyph row for fringe update if periodicity changed.
20314 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20315 for fringe update unless it has periodic bitmap.

20335 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20336 Remove macros that are defined and never used.
20337 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20339 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20341 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20342 (Fx_get_selection_internal): Minor cleanup.

20370 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20372 * systime.h (Time): Define only if emacs is defined.
20373 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20374 where the include path doesn't have X11/X.h by default. See
20375 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20377 2011-05-20 Kenichi Handa <handa@m17n.org>
20379 * composite.c (find_automatic_composition): Fix previous change.
20381 2011-05-20 Glenn Morris <rgm@gnu.org>

20392 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20393 (lisp): Set the order to that of loadup.el.
20394 (shortlisp): Make it a copy of $lisp.
20395 (SOME_MACHINE_LISP): Remove.
20396 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20397 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20399 2011-05-18 Kenichi Handa <handa@m17n.org>
20401 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20402 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20403 (find_automatic_composition): Mostly rewrite for efficiency.
20405 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20407 * makefile.w32-in: Update dependencies.
20409 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20411 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20412 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20414 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20416 Fix some integer overflow issues, such as string length overflow.
20418 * insdel.c (count_size_as_multibyte): Check for string overflow.
20420 * character.c (lisp_string_width): Check for string overflow.
20421 Use EMACS_INT, not int, for string indexes and lengths; in
20422 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20423 the resulting string length overflows an EMACS_INT; instead,
20424 report a string overflow if no precision given. When checking for
20425 precision exhaustion, use a check that cannot possibly have
20426 integer overflow. (Bug#8675)
20427 * character.h (lisp_string_width): Adjust to new signature.
20429 * alloc.c (string_overflow): New function.
20430 (Fmake_string): Use it. This doesn't change behavior, but saves
20431 a few bytes and will simplify future changes.
20432 * character.c (string_escape_byte8): Likewise.
20433 * lisp.h (string_overflow): New decl.
20435 Fixups, following up to the user-interface timestamp change.
20436 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20437 for UI timestamps, instead of unsigned long.
20438 * msdos.c (mouse_get_pos): Likewise.
20439 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20440 * w32gui.h (Time): Define by including "systime.h" rather than by
20441 declaring it ourselves. (Bug#8664)
20443 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20444 * image.c (clear_image_cache): Likewise.
20446 * term.c (term_mouse_position): Don't assume time_t wraparound.
20448 Be more systematic about user-interface timestamps.
20449 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20450 and sometimes 'EMACS_UINT', to represent these timestamps.
20451 This change causes it to use 'Time' uniformly, as that's what X uses.
20452 This makes the code easier to follow, and makes it easier to catch
20453 integer overflow bugs such as Bug#8664.
20454 * frame.c (Fmouse_position, Fmouse_pixel_position):
20455 Use Time, not unsigned long, for user-interface timestamps.
20456 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20457 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20458 * keyboard.h (last_event_timestamp): Likewise.
20459 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20460 * menu.h (xmenu_show): Likewise.
20461 * term.c (term_mouse_position): Likewise.
20462 * termhooks.h (struct input_event.timestamp): Likewise.
20463 (struct terminal.mouse_position_hook): Likewise.
20464 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20465 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20466 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20467 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20468 what it was before.
20469 * menu.h, termhooks.h: Include "systime.h", for Time.
20471 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20472 Don't assume that the difference between two unsigned long values
20473 can fit into an integer. At this point, we know button_down_time
20474 <= event->timestamp, so the difference must be nonnegative, so
20475 there's no need to cast the result if double-click-time is
20476 nonnegative, as it should be; check that it's nonnegative, just in
20477 case. This bug is triggered when events are more than 2**31 ms
20478 apart (about 25 days). (Bug#8664)
20480 * xselect.c (last_event_timestamp): Remove duplicate decl.
20481 (x_own_selection): Remove needless cast to unsigned long.
20483 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20484 that always fit in int. Use a sentinel instead of a counter, to
20485 avoid a temp and to allay GCC's concerns about possible int overflow.
20486 * frame.h (struct frame): Use int for menu_bar_items_used
20487 instead of EMACS_INT, since it always fits in int.
20489 * menu.c (grow_menu_items): Check for int overflow.
20491 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20493 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20494 Before, the code was not consistent. These values cannot exceed
20495 2**31 - 1 so there's no need to make them unsigned.
20496 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20497 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20498 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20500 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20502 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20503 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20504 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20505 presumably because the widths might not match.
20507 * window.c (size_window): Avoid needless test at loop start.
20509 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20511 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20513 2011-05-12 Drew Adams <drew.adams@oracle.com>
20515 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20517 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20519 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20520 `width' to `bar_area_x' and `bar_area_width', respectively.
20521 (x_scroll_run): Take account of fringe background extension.
20523 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20524 Rename local vars `left' and `width' to `bar_area_x' and
20525 `bar_area_width', respectively.
20526 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20527 background extension.
20529 2011-05-10 Jim Meyering <meyering@redhat.com>
20531 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20533 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20535 * image.c (Finit_image_library): Return t for built-in image types,
20536 like pbm and xbm. (Bug#8640)
20538 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20540 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20542 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20544 * w32console.c (Fset_screen_color): Doc fix.
20545 (Fget_screen_color): New function.
20546 (syms_of_ntterm): Defsubr it.
20548 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20549 unlink the temporary file if Fcall_process didn't create it in the
20551 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20552 child process will be redirected to a file specified with `:file'.
20553 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20554 cue to call_process_cleanup not to close that handle.
20556 2011-05-07 Ben Key <bkey76@gmail.com>
20558 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20559 one of two shell specific rules, either bootstrap-temacs-CMD or
20560 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20561 to the previous implementation of the bootstrap-temacs rule.
20562 The bootstrap-temacs-CMD rule is similar to the previous
20563 implementation of the bootstrap-temacs rule except that it
20564 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20567 These changes, along with some changes to nt/configure.bat,
20568 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20569 earlier fix to add support for --cflags and --ldflags options
20570 that include quotes so that it works whether make uses cmd or
20573 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20575 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20576 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20578 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20579 a string. Handle both cases.
20580 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20581 (Fdbus_register_method): Use Qinvalid_function.
20583 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20585 * makefile.w32-in: Update dependencies.
20586 (LISP_H): Add inttypes.h and stdin.h.
20587 (PROCESS_H): Add unistd.h.
20589 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20591 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20592 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20594 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20596 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20598 * term.c (vfatal): Remove stray call to va_end.
20599 It's not needed and the C Standard doesn't allow it here anyway.
20601 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20602 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20604 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20607 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20609 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20611 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20613 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20615 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20617 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20618 * charset.c (Fdefine_charset_internal): Don't initialize
20619 charset.code_space[15]. The value was garbage, on hosts with
20620 32-bit int (Bug#8600).
20622 * lread.c (read_integer): Be more consistent with string-to-number.
20623 Use string_to_number to do the actual conversion; this avoids
20624 rounding errors and fixes some other screwups. Without this fix,
20625 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20626 (digit_to_number): Move earlier, for benefit of read_integer.
20627 Return -1 if the digit is out of range for the base, -2 if it is
20628 not a digit in any supported base. (Bug#8602)
20630 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20632 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20633 to match comment at start of function. This also removes a
20634 GCC warning about overflow in a 32+64-bit port.
20636 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20638 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20639 Reported by Stefan Monnier in
20640 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20641 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20642 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20644 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20645 (EMACS_UINTPTR): Likewise, with uintptr_t.
20647 * lisp.h: Prefer 64-bit EMACS_INT if available.
20648 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20649 on 32-bit hosts that have 64-bit int, so that they can access
20651 However, temporarily disable this change unless the temporary
20652 symbol WIDE_EMACS_INT is defined.
20654 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20656 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20657 This removes an assumption that EMACS_INT and long are the same
20658 width as pointers. The assumption is true for Emacs porting targets
20659 now, but we want to make other targets possible.
20660 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20661 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20662 In the rest of the code, change types of integers that hold casted
20663 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20664 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20665 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20666 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20667 No need to cast type when ORing.
20668 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20669 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20670 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20671 assume EMACS_INT is the same width as char *.
20672 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20673 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20674 Remove no-longer-needed casts.
20675 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20676 (xg_tool_bar_help_callback, xg_make_tool_item):
20677 Use EMACS_INTPTR to hold an integer
20678 that will be cast to void *; this can avoid a GCC warning
20679 if EMACS_INT is not the same width as void *.
20680 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20681 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20682 (current_message_1, set_message_1):
20683 Use a local to convert to proper width without a cast.
20684 * xmenu.c (dialog_selection_callback): Likewise.
20686 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20687 Also, don't assume VALBITS / RAND_BITS is less than 5,
20688 and don't rely on undefined behavior when shifting a 1 left into
20690 * lisp.h (get_random): Change signature to match.
20692 * lread.c (hash_string): Use size_t, not int, for hash computation.
20693 Normally we prefer signed values; but hashing is special, because
20694 it's better to use unsigned division on hash table sizes so that
20695 the remainder is nonnegative. Also, size_t is the natural width
20696 for hashing into memory. The previous code used 'int', which doesn't
20697 retain enough info to hash well into very large tables.
20698 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20700 * dbusbind.c: Don't possibly lose pointer info when converting.
20701 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20702 Use XPNTR rather than XHASH, so that the high-order bits of
20703 the pointer aren't lost when converting through void *.
20705 * eval.c (Fautoload): Don't double-shift a pointer.
20707 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20709 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20711 * gnutls.c (DEF_GNUTLS_FN):
20712 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20714 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20716 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20719 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20721 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20722 New version that can reserve upto 2GB of heap space.
20724 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20726 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20728 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20730 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20731 `gnutls_certificate_set_x509_key_file'.
20733 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20735 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20736 Update dependencies.
20738 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20740 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20741 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20742 Remove unused parameter `fildes'.
20743 * process.c (read_process_output, send_process): Don't pass it.
20745 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20747 Fix previous change: the library cache is defined in w32.c.
20748 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20749 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20751 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20753 Implement dynamic loading of GnuTLS on Windows.
20755 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20756 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20757 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20760 * gnutls.c (Qgnutls_dll): Define.
20761 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
20762 (gnutls_*): Declare function pointers.
20763 (init_gnutls_functions): New function to initialize function pointers.
20764 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
20765 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
20766 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20767 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
20768 (emacs_gnutls_write, emacs_gnutls_read)
20769 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20770 (Fgnutls_available_p): New function.
20771 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
20772 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
20773 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
20775 * image.c: Include w32.h.
20776 (Vimage_type_cache): Delete.
20777 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
20778 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
20779 (w32_delayed_load): Move to w32.c.
20781 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20783 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20784 (w32_delayed_load): Move from image.c. When loading a library, record
20785 its filename in the :loaded-from property of the library id.
20786 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20787 Initialize and staticpro them.
20788 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20790 * process.c: Include lisp.h before w32.h, not after.
20791 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20792 instead of gnutls_record_check_pending.
20794 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20796 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20798 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20799 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20802 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20804 * xterm.c (x_set_frame_alpha): Do not set property on anything
20805 else than FRAME_X_OUTER_WINDOW (Bug#8608).
20807 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20809 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
20811 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20813 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
20814 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
20815 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

20820 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
20821 (Qgnutls_bootprop_callbacks_verify): Make static.

20833 * sysdep.c (interruptible_wait_for_termination): New function
20834 which is like wait_for_termination, but allows keyboard
20837 * callproc.c (Fcall_process): Add (:file "file") as an option for
20839 (Fcall_process_region): Ditto.
20841 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20843 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20844 rather than `XVECTOR (FOO)->size'.
20846 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20847 inttypes.h, as a gnulib replacement is used if it not available in
20850 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20852 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20853 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20854 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20856 * coding.c (coding_alloc_by_realloc): Error out if destination
20857 will grow beyond MOST_POSITIVE_FIXNUM.
20858 (decode_coding_emacs_mule): Abort if there isn't enough place in
20859 charbuf for the composition carryover bytes. Reserve an extra
20860 space for up to 2 characters produced in a loop.
20861 (decode_coding_iso_2022): Abort if there isn't enough place in
20862 charbuf for the composition carryover bytes.
20864 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20866 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
20867 aborting when %lld or %lll format is passed.
20868 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20869 %llo or %llx format is passed. (Bug#8545)
20871 * window.c (window_scroll_line_based): Use a marker instead of
20872 simple variables to record original value of point. (Bug#7952)
20874 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20875 produced by %s or %c overflows available buffer space. (Bug#8545)
20877 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20879 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20880 (SIZE_MAX): Move defn after all includes, as they might #define it.
20882 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20884 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20886 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20888 * keyboard.c (Qdelayed_warnings_hook): Define.
20889 (command_loop_1): Run `delayed-warnings-hook'
20890 if Vdelayed_warnings_list is non-nil.
20891 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20892 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20894 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20896 * doprnt.c (doprnt): Don't return value smaller than the buffer
20897 size if the message was truncated. (Bug#8545).
20899 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20901 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20902 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20904 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20906 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20908 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20910 * makefile.w32-in: Update dependencies.
20912 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20914 Improve `doprnt' and its usage. (Bug#8545)
20915 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20916 `format_end'. Remove support for %l as a conversion specifier.
20917 Don't use xrealloc. Improve diagnostics when the %l size modifier
20918 is used. Update the commentary.
20920 * eval.c (verror): Simplify calculation of size_t.
20922 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20925 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20927 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20930 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20932 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20933 This makes this file independent of the recent pseudovector change.
20935 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20937 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20939 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20940 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20941 Remove unused local.
20942 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20944 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20945 GCC 4.6.0 optimizes based on type-based alias analysis.
20946 For example, if b is of type struct buffer * and v of type struct
20947 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20948 != &v->size, and therefore "v->size = 1; b->size = 2; return
20949 v->size;" must therefore return 1. This assumption is incorrect
20950 for Emacs, since it type-puns struct Lisp_Vector * with many other
20951 types. To fix this problem, this patch adds a new type struct
20952 vectorlike_header that documents the constraints on layout of vectors
20953 and pseudovectors, and helps optimizing compilers not get fooled
20954 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20955 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20956 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20958 (XSETPVECTYPE): Rewrite in terms of new macro.
20959 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20960 This is a bit clearer, and further avoids the possibility of
20961 undesirable aliasing.
20962 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20963 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20964 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20965 since Lisp_Subr is a special case (no "next" field).
20966 (ASIZE): Now uses header.size rather than size.
20967 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20968 to avoid the hassle of writing XVECTOR (foo)->header.size.
20969 (struct vectorlike_header): New type.
20970 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20971 object, to help avoid aliasing.
20972 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20973 (SUBRP): Likewise, since Lisp_Subr is a special case.
20974 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20975 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20976 (struct Lisp_Hash_Table): Combine first two members into a single
20977 struct vectorlike_header member. All uses of "size" and "next" members
20978 changed to be "header.size" and "header.next".
20979 * buffer.h (struct buffer): Likewise.
20980 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20981 * frame.h (struct frame): Likewise.
20982 * process.h (struct Lisp_Process): Likewise.
20983 * termhooks.h (struct terminal): Likewise.
20984 * window.c (struct save_window_data, struct saved_window): Likewise.
20985 * window.h (struct window): Likewise.
20986 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20987 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20988 * buffer.c (init_buffer_once): Likewise.
20989 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20991 * process.c (Fformat_network_address): Use local var for size,
20994 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20996 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20997 * data.c (atof): Remove decl; no longer used or needed.
20998 (digit_to_number): Move to lread.c.
20999 (Fstring_to_number): Use new string_to_number function, to be
21000 consistent with how the Lisp reader treats infinities and NaNs.
21001 Do not assume that floating-point numbers represent EMACS_INT
21002 without losing information; this is not true on most 64-bit hosts.
21003 Avoid double-rounding errors, by insisting on integers when
21004 parsing non-base-10 numbers, as the documentation specifies.
21005 * lisp.h (string_to_number): New decl, replacing ...
21006 (isfloat_string): Remove.
21007 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21008 (read1): Do not accept +. and -. as integers; this
21009 appears to have been a coding error. Similarly, do not accept
21010 strings like +-1e0 as floating point numbers. Do not report
21011 overflow for integer overflows unless the base is not 10 which
21012 means we have no simple and reliable way to continue.
21013 Break out the floating-point parsing into a new
21014 function string_to_number, so that Fstring_to_number parses
21015 floating point numbers consistently with the Lisp reader.
21016 (digit_to_number): Move here from data.c. Make it static inline.
21017 (E_CHAR, EXP_INT): Remove, replacing with ...
21018 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21019 (string_to_number): New function, replacing isfloat_string.
21020 This function checks for valid syntax and produces the resulting
21021 Lisp float number too. Rework it so that string-to-number
21022 no longer mishandles examples like "1.0e+". Use strtoumax,
21023 so that overflow for non-base-10 numbers is reported only when
21024 there's no portable and simple way to convert to floating point.
21026 * textprop.c (set_text_properties_1): Rewrite for clarity,
21027 and to avoid GCC warning about integer overflow.
21029 * intervals.h (struct interval): Use EMACS_INT for members
21030 where EMACS_UINT might cause problems. See
21031 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21032 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21033 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21035 (offset_intervals): Tell GCC not to worry about length overflow
21036 when negating a negative length.
21038 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21039 (overrun_check_free): Likewise.
21041 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21042 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21045 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21046 (gnutls_make_error): Rename local to avoid shadowing.
21047 (gnutls_emacs_global_deinit): ifdef out; not used.
21048 (Fgnutls_boot): Use const for pointer to readonly storage.
21049 Comment out unused local. Fix pointer signedness problems.
21051 * lread.c (openp): Don't stuff size_t into an 'int'.
21052 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21053 about possible signed overflow.
21055 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21056 (GDK_KEY_g): Don't define if already defined.
21057 (xg_prepare_tooltip): Avoid pointer signedness problem.
21058 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21060 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21061 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21063 * xfns.c (Fx_window_property): Simplify a bit,
21064 to make a bit faster and to avoid GCC 4.6.0 warning.
21065 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21067 * fns.c (internal_equal): Don't assume size_t fits in int.
21069 * alloc.c (compact_small_strings): Tighten assertion a little.
21071 Replace pEd with more-general pI, and fix some printf arg casts.
21072 * lisp.h (pI): New macro, generalizing old pEd macro to other
21073 conversion specifiers. For example, use "...%"pI"d..." rather
21074 than "...%"pEd"...".
21075 (pEd): Remove. All uses replaced with similar uses of pI.
21076 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21077 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21078 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21079 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21080 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21081 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21082 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21084 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21085 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21086 * print.c (safe_debug_print, print_object): Likewise.
21087 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21089 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21090 avoiding the 0 flag, which is not portable.
21091 * process.c (Fmake_network_process): Use pI to avoid cast.
21092 * region-cache.c (pp_cache): Likewise.
21093 * xdisp.c (decode_mode_spec): Likewise.
21094 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21095 behavior on 64-bit hosts with printf arg.
21096 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21097 (x_stop_queuing_selection_requests): Likewise.
21098 (x_get_window_property): Don't truncate byte count to an 'int'
21101 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21102 here, since it parses constructs like leading '-' and spaces,
21103 which are not wanted; and it overflows with large numbers.
21104 Instead, simply match F[0-9]+, which is what is wanted anyway.
21106 * alloc.c: Remove unportable assumptions about struct layout.
21107 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21108 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21109 (allocate_vectorlike, make_pure_vector): Use the new macros,
21110 plus offsetof, to remove unportable assumptions about struct layout.
21111 These assumptions hold on all porting targets that I know of, but
21112 they are not guaranteed, they're easy to remove, and removing them
21113 makes further changes easier.
21115 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21116 This doesn't fix a bug but makes the code clearer.
21117 (string_overrun_cookie): Now const. Use initializers that
21118 don't formally overflow signed char, to avoid warnings.
21119 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21120 can cause Emacs to crash when string overrun checking is enabled.
21121 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21122 multiple of sizeof (EMACS_INT); it need not be, if
21123 alignof(EMACS_INT) < sizeof (EMACS_INT).
21124 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21126 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
21128 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
21130 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
21132 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
21133 supposed to be handshaking. (Bug#8556)
21134 Reported by Paul Eggert <eggert@cs.ucla.edu>.
21136 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
21138 * lisp.h (Qdebug): List symbol.
21139 * eval.c (Qdebug): Restore global linkage.
21140 * keyboard.c (debug-on-event): New variable.
21141 (handle_user_signal): Break into debugger when debug-on-event
21142 matches the current signal symbol.
21144 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
21146 * alloc.c (check_sblock, check_string_bytes)
21147 (check_string_free_list): Convert to standard C.
21149 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
21151 * w32.c (emacs_gnutls_push): Fix typo.
21153 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21155 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21156 "cast to pointer from integer of different size".
21158 Improve doprnt and its use in verror. (Bug#8545)
21159 * doprnt.c (doprnt): Document the set of format control sequences
21160 supported by the function. Use SAFE_ALLOCA instead of always
21163 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21164 is one byte too soon. Don't use xrealloc; instead xfree and
21167 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21169 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21172 * gnutls.c: Renamed global_initialized to
21173 gnutls_global_initialized. Added internals for the
21174 :verify-hostname-error, :verify-error, and :verify-flags
21175 parameters of `gnutls-boot' and documented those parameters in the
21176 docstring. Start callback support.
21177 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21178 unless a fatal error occurred. Call gnutls_alert_send_appropriate
21179 on error. Return error code.
21180 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
21181 (emacs_gnutls_read): Likewise.
21182 (Fgnutls_boot): Return handshake error code.
21183 (emacs_gnutls_handle_error): New function.
21184 (wsaerror_to_errno): Likewise.
21186 * w32.h (emacs_gnutls_pull): Add prototype.
21187 (emacs_gnutls_push): Likewise.
21189 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
21190 (emacs_gnutls_push): Likewise.
21192 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
21194 * process.c (wait_reading_process_output): Check if GnuTLS
21195 buffered some data internally if no FDs are set for TLS
21198 * makefile.w32-in (OBJ2): Add gnutls.$(O).
21199 (LIBS): Link to USER_LIBS.

21205 display_replaced_before_p argument into display_replaced_p, to
21206 make it consistent with the commentary. Fix typos in the
21209 * textprop.c (syms_of_textprop): Remove dead code.

21215 to changes in oldXMenu/XMenu.h from 2011-04-16.
21216 <menu_help_message, prev_menu_help_message>: Constify.
21217 (IT_menu_make_room): menu->help_text is now `const char **';
21220 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
21221 to changes in oldXMenu/XMenu.h from 2011-04-16.
21222 (struct XMenu): Declare `help_text' `const char **'.

21233 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
21235 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
21238 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
21239 changes in globals.h immediately force recompilation.
21240 (TAGS): Depend on $(CURDIR)/m/intel386.h and
21241 $(CURDIR)/s/ms-w32.h.
21242 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

21245 (syms_of_character): Don't defsubr it.
21246 <char-direction-table>: Deleted.
21248 2011-04-23 Eli Zaretskii <eliz@gnu.org>
21250 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
21251 * doprnt.c: Include limits.h.
21252 (SIZE_MAX): New macro.
21253 (doprnt): Return a size_t value. 2nd arg is now size_t.
21254 Many local variables are now size_t instead of int or unsigned.
21255 Improve overflow protection. Support `l' modifier for integer
21256 conversions. Support %l conversion. Don't assume an EMACS_INT
21257 argument for integer conversions and for %c.
21259 * lisp.h (doprnt): Restore prototype.
21261 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
21262 $(SRC)/character.h.
21264 * Makefile.in (base_obj): Add back doprnt.o.

21507 * process.c (send_process): Adjust to the new signatures of
21508 emacs_write and emacs_gnutls_write. Do not attempt to store

21732 * editfns.c, lisp.h (get_operating_system_release): Remove.
21733 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
21734 worth the hassle of breaking this out.
21736 * xterm.c: Make symbols static if they're not exported.
21737 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
21738 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

21838 * lisp.h: Remove these decls.
21840 * buffer.c (buffer_count): Remove unused var.
21842 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

21844 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
21845 * dispextern.h (bidi_dump_cached_states): Remove, since it's
21846 exported only to the debugger.

21849 * atimer.h (run_all_atimers): Remove; not exported.
21851 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
21852 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
21853 was inaccessible from Lisp.
21854 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
21855 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
21857 alloc.c: Import and export fewer symbols, and remove unused items.
21858 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
21860 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
21861 it's not optimized away by whole-program optimization.
21862 (message_enable_multibyte, free_misc): Remove.
21863 (catchlist, handlerlist, mark_backtrace):
21864 Declare only if BYTE_MARK_STACK.

21873 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
21874 (mark_backtrace): Define only if BYTE_MARK_STACK.
21875 * xdisp.c (message_enable_multibyte): Now static.
21877 Declare Lisp_Object Q* variables to be 'static' if not exported.
21878 This makes it easier for human readers (and static analyzers)
21879 to see whether these variables are used from other modules.
21880 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
21881 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
21882 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

21890 Remove decls of unexported vars.
21891 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21893 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21895 Make Emacs functions such as Fatom 'static' by default.
21896 This makes it easier for human readers (and static analyzers)
21897 to see whether these functions can be called from other modules.
21898 DEFUN now defines a static function. To make the function external
21899 so that it can be used in other C modules, use the new macro DEFUE.
21900 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21901 (Finit_image_library):
21902 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21903 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21904 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21905 Remove decls, since these functions are now static.
21906 (Funintern, Fget_internal_run_time): New decls, since these functions
21907 were already external.
21909 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21910 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

21916 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21917 Mark functions with DEFUE instead of DEFUN,
21918 if they are used in other modules.
21919 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21920 decls for now-static functions.
21921 * buffer.h (Fdelete_overlay): Remove decl.
21922 * callproc.c (Fgetenv_internal): Mark as internal.
21923 * composite.c (Fremove_list_of_text_properties): Remove decl.

21930 * fileio.c (Fmake_symbolic_link): New forward static decl.
21931 * image.c (Finit_image_library): New forward static decl.
21932 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21933 * intervals.h (Fprevious_property_change):
21934 (Fremove_list_of_text_properties): Remove decls.
21935 * keyboard.c (Fthis_command_keys): Remove decl.
21936 (Fcommand_execute): New forward static decl.

21952 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
21954 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21957 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21959 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21960 when at ZV. (Bug#8487)
21962 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21964 * charset.c (Fclear_charset_maps): Use xfree instead of free.

21968 * termcap.c (tgetent): Likewise.
21969 * xfns.c (x_default_font_parameter): Likewise.
21970 * xsettings.c (read_and_apply_settings): Likewise.
21972 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21973 (overrun_check_free): Protoize.
21975 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21977 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21978 since callers should never pass a negative size.
21979 Change the signature to match that of plain 'read' and 'write'; see
21980 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21981 * lisp.h: Update prototypes of emacs_write and emacs_read.
21983 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21985 * xdisp.c (redisplay_window): Don't try to determine the character
21986 position of the scroll margin if the window start point w->startp
21987 is outside the buffer's accessible region. (Bug#8468)
21989 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21991 Fix write-region and its subroutines for buffers > 2GB.
21992 * fileio.c (a_write, e_write): Modify declaration of arguments and
21993 local variables to support buffers larger than 2GB.
21994 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21996 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21997 argument, local variables, and return value.
21999 * lisp.h: Update prototypes of emacs_write and emacs_read.
22001 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22003 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22005 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22007 Fix more problems found by GCC 4.6.0's static checks.
22009 * xdisp.c (vmessage): Use a better test for character truncation.
22011 * charset.c (load_charset_map): <, not <=, for optimization,
22012 and to avoid potential problems with integer overflow.
22013 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22014 * casetab.c (set_identity, shuffle): Likewise.
22015 * editfns.c (Fformat): Likewise.
22016 * syntax.c (skip_chars): Likewise.
22018 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22019 This also lets GCC 4.6.0 generate slightly better loop code.
22021 * callint.c (Fcall_interactively): <, not <=, for optimization.
22022 (Fcall_interactively): Count the number of arguments produced,
22023 not the number of arguments given. This is simpler and lets GCC
22024 4.6.0 generate slightly better code.
22026 * ftfont.c: Distingish more carefully between FcChar8 and char.
22027 The previous code passed unsigned char * to a functions like
22028 strlen and xstrcasecmp that expect char *, which does not
22029 conform to the C standard.
22030 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22031 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22032 char * when the C standard requires it.
22034 * keyboard.c (read_char): Remove unused var.
22036 * eval.c: Port to Windows vsnprintf (Bug#8435).
22037 Include <limits.h>.
22038 (SIZE_MAX): Define if the headers do not.
22039 (verror): Do not give up if vsnprintf returns a negative count.
22040 Instead, grow the buffer. This ports to Windows vsnprintf, which
22041 does not conform to C99. Problem reported by Eli Zaretskii.
22042 Also, simplify the allocation scheme, by avoiding the need for
22043 calling realloc, and removing the ALLOCATED variable.
22045 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22047 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22048 But keep the doprint source code for now, as we might revamp it
22049 and use it again (Bug#8435).
22050 * lisp.h (doprnt): Remove.
22051 * Makefile.in (base_obj): Remove doprnt.o.
22052 * deps.mk (doprnt.o): Remove.
22054 error: Print 32- and 64-bit integers portably (Bug#8435).
22055 Without this change, on typical 64-bit hosts error ("...%d...", N)
22056 was used to print both 32- and 64-bit integers N, which relied on
22057 undefined behavior.
22058 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22059 * lisp.h (error, verror): Mark as printf-like functions.
22060 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22061 Report overflow in size calculations when allocating printf buffer.
22062 Do not truncate output string at its first null byte.
22063 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22064 Truncate the output at a character boundary, since vsnprintf does not
22066 * charset.c (check_iso_charset_parameter): Convert internal
22067 character to string before calling 'error', since %c now has the
22069 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22070 overflow when computing char to be passed to 'error'. Do not
22071 pass Lisp_Object to 'error'; pass the integer instead.
22072 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22073 formatted with plain %d.
22075 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22077 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22079 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22081 * xterm.c (x_catch_errors): Remove duplicate declaration.
22083 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22085 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22087 2011-04-10 Jim Meyering <meyering@redhat.com>
22089 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22090 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22091 return ssize_t not "int", and use size_t as the buffer length.
22092 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22093 * gnutls.h: Update declarations.
22094 * process.c (read_process_output): Use ssize_t, to match.
22095 (send_process): Likewise.
22097 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22099 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22101 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22103 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22104 Use unsigned char, to match FcChar8 type definition.
22106 * xterm.c (handle_one_xevent):
22107 * xmenu.c (create_and_show_popup_menu):
22108 * xselect.c (x_decline_selection_request)
22109 (x_reply_selection_request): Avoid type-punned deref of X events.
22111 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22113 Fix some uses of `int' instead of EMACS_INT.
22114 * search.c (string_match_1, fast_string_match)
22115 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22116 (scan_buffer, find_next_newline_no_quit)
22117 (find_before_next_newline, search_command, Freplace_match)
22118 (Fmatch_data): Make some `int' variables be EMACS_INT.
22120 * xdisp.c (display_count_lines): 3rd argument and return value now
22121 EMACS_INT. All callers changed.
22122 (pint2hrstr): Last argument is now EMACS_INT.
22124 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22125 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22126 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

22129 (decode_coding_ccl, decode_coding_charset)
22130 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.

22132 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
22133 <char_offset, last_offset>: Declare EMACS_INT.

22167 instead of using internal_with_output_to_temp_buffer.
22168 (Qhelp_form_show): New var.
22169 (syms_of_keyboard): Use DEFSYM macro.
22171 * print.c (internal_with_output_to_temp_buffer): Function deleted.

22184 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22186 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22188 Fix more problems found by GCC 4.6.0's static checks.
22190 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
22192 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22194 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22196 * xdisp.c (vmessage): Mark as a printf-like function.
22198 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

22205 to system-supplied API.
22207 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22209 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22210 This avoids several warnings with gcc -Wstrict-overflow.
22211 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22212 directly, rather than having caller test rule sign. This avoids
22213 some unnecessary tests.
22214 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22215 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22216 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22218 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22219 (xfont_open): Avoid unnecessary tests.
22221 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22223 * composite.h, composite.c (composition_gstring_put_cache):
22224 Use EMACS_INT, not int, for length.
22226 * composite.h (COMPOSITION_DECODE_REFS): New macro,
22227 breaking out part of COMPOSITION_DECODE_RULE.
22228 (COMPOSITION_DECODE_RULE): Use it.
22229 * composite.c (get_composition_id): Remove unused local vars,
22230 by using the new macro.
22232 * textprop.c (set_text_properties_1): Change while to do-while,
22233 since the condition is always true at first.
22235 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22236 (interval_deletion_adjustment): Return unsigned value.
22239 * process.c (list_processes_1, create_pty, read_process_output):
22240 (exec_sentinel): Remove vars that were set but not used.
22241 (create_pty): Remove unnecessary "volatile"s.
22242 (Fnetwork_interface_info): Avoid possibility of int overflow.
22243 (read_process_output): Do adaptive read buffering even if carryover.
22244 (read_process_output): Simplify nbytes computation if buffered.

22248 * syntax.c (scan_words): Remove var that was set but not used.
22249 (update_syntax_table): Use unsigned instead of int.
22251 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

22253 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
22255 * print.c (print_error_message): Avoid int overflow.
22257 * font.c (font_list_entities): Redo for clarity,
22258 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22260 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22261 (font_score): Avoid potential overflow in diff calculation.
22263 * fns.c (substring_both): Remove var that is set but not used.
22264 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22266 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22268 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22269 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22270 can always succeed if overflow has undefined behavior.
22272 * search.c (boyer_moore, wordify): Remove vars set but not used.
22273 (wordify): Omit three unnecessary tests.
22275 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22276 All callers changed. This avoids the need for an unused var.
22278 * casefiddle.c (casify_region): Remove var that is set but not used.
22280 * dired.c (file_name_completion): Remove var that is set but not used.
22282 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22284 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22285 (Finsert_file_contents): Remove unnecessary code checking fd.
22287 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22288 Check for integer overflow on size calculations.
22290 * buffer.c (Fprevious_overlay_change): Remove var that is set
22293 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22294 Remove vars that are set but not used.
22295 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22296 (timer_check_2): Mark vars as initialized.
22298 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22300 * image.c (lookup_image): Remove var that is set but not used.
22301 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22303 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22304 that are set but not used.
22306 * xfns.c (make_invisible_cursor): Don't return garbage
22307 if XCreateBitmapFromData fails (Bug#8410).
22309 * xselect.c (x_get_local_selection, x_handle_property_notify):
22310 Remove vars that are set but not used.
22312 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
22313 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
22315 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
22316 Remove var that is set but not used.
22317 (scroll_bar_windows_size): Now size_t, not int.
22318 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
22319 Check for overflow.
22321 * xfaces.c (realize_named_face): Remove vars that are set but not used.
22322 (map_tty_color) [!defined MSDOS]: Likewise.
22324 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22326 * coding.c: Remove vars that are set but not used.
22327 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22328 All callers changed.
22329 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22330 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22331 (decode_coding_charset): Remove vars that are set but not used.
22333 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22334 that is set but not used.
22336 * print.c (print_object): Remove var that is set but not used.
22338 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22339 The gnulib version avoids calling malloc in the usual case,
22340 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22341 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22342 * filelock.c (current_lock_owner): Likewise.
22343 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22344 * sysdep.c: Include allocator.h, careadlinkat.h.
22345 (emacs_no_realloc_allocator): New static constant.
22346 (emacs_readlink): New function.
22347 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22348 ../lib/careadlinkat.h.
22350 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22352 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22353 first non-nil return value).
22355 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
22357 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
22358 if not defined (Bug#8403).
22360 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22362 * xdisp.c (display_count_lines): Remove parameter `start',
22363 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22364 (get_char_face_and_encoding): Remove parameter `multibyte_p',
22365 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

22367 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22368 and thereabouts. All callers changed.
22369 (get_per_char_metric): Remove parameter `f', unused since
22370 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
22372 2011-04-02 Jim Meyering <meyering@redhat.com>
22374 do not dereference NULL upon failed strdup
22375 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22376 (ns_get_family): Likewise.
22378 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22380 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
22382 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
22384 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
22387 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
22389 Add lexical binding.
22391 * window.c (Ftemp_output_buffer_show): New fun.
22392 (Fsave_window_excursion):
22393 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
22395 * lread.c (lisp_file_lexically_bound_p): New function.
22396 (Fload): Bind Qlexical_binding.
22397 (readevalloop): Remove `evalfun' arg.
22398 Bind Qinternal_interpreter_environment.
22399 (Feval_buffer): Bind Qlexical_binding.
22400 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
22402 (syms_of_lread): Declare `lexical-binding'.
22404 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22406 * keyboard.c (eval_dyn): New fun.
22407 (menu_item_eval_property): Use it.
22409 * image.c (parse_image_spec): Use Ffunctionp.
22411 * fns.c (concat, mapcar1): Accept byte-code-functions.
22413 * eval.c (Fsetq): Handle lexical vars.
22414 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22415 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22416 (FletX, Flet): Obey lexical binding.
22417 (Fcommandp): Handle closures.
22418 (Feval): New `lexical' arg.
22419 (eval_sub): New function extracted from Feval. Use it almost
22420 everywhere where Feval was used. Look up vars in lexical env.
22422 (Ffunctionp): Move from subr.el.
22423 (Ffuncall): Handle closures.
22424 (apply_lambda): Remove `eval_flags'.
22425 (funcall_lambda): Handle closures and new byte-code-functions.
22426 (Fspecial_variable_p): New function.
22427 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22428 but without exporting it to Lisp.
22430 * doc.c (Fdocumentation, store_function_docstring):
22431 * data.c (Finteractive_form): Handle closures.
22433 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22436 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22438 (exec_byte_code): New function extracted from Fbyte_code to handle new
22439 calling convention for byte-code-functions. Add new byte-codes.
22441 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22443 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22445 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22447 * xdisp.c (redisplay_internal): Fix prototype.
22449 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22451 * xdisp.c (SCROLL_LIMIT): New macro.
22452 (try_scrolling): Use it when setting scroll_limit.
22453 Limit scrolling to 100 screen lines.
22454 (redisplay_window): Even when falling back on "recentering",
22455 position point in the window according to scroll-conservatively,
22456 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22458 (try_scrolling): When point is above the window, allow searching
22459 as far as scroll_max, or one screenful, to compute vertical
22460 distance from PT to the scroll margin position. This prevents
22461 try_scrolling from unnecessarily failing when
22462 scroll-conservatively is set to a value slightly larger than the
22463 window height. Clean up the case of PT below the margin at bottom
22464 of window: scroll_max can no longer be INT_MAX. When aggressive
22465 scrolling is in use, don't let point enter the opposite scroll
22466 margin as result of the scroll.
22467 (syms_of_xdisp) <scroll-conservatively>: Document the
22468 threshold of 100 lines for never-recentering scrolling.
22470 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22472 * dispextern.h (move_it_by_lines):
22473 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
22474 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
22475 (message_log_check_duplicate): Remove parameters `prev_bol' and
22476 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22477 (redisplay_internal): Remove parameter `preserve_echo_area',
22478 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22480 * indent.c (Fvertical_motion):
22481 * window.c (window_scroll_pixel_based, Frecenter):
22482 Don't pass `need_y_p' to `move_it_by_lines'.
22484 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22486 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22487 steal a few bits to be more compact.
22488 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22489 Remove unneeded casts.
22491 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22493 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22495 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22496 binding" message (bug#7967).
22498 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22500 Fix more problems found by GCC 4.6.0's static checks.
22502 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22503 Remove unused local var.
22505 * editfns.c (Fmessage_box): Remove unused local var.
22507 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22508 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22509 Omit unused local vars.
22510 * window.c (shrink_windows): Omit unused local var.
22511 * menu.c (digest_single_submenu): Omit unused local var.
22512 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22513 Omit unused local var.
22515 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22516 Don't assume string length fits in int.
22517 (keyremap_step, read_key_sequence): Use size_t for sizes.
22518 (read_key_sequence): Don't check last_real_key_start redundantly.
22520 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22521 instead of alloca (Bug#8344).
22523 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22524 (Fbacktrace_frame): Don't assume nframes fits in int.
22526 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22528 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22531 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22533 * cm.c (calccost): Turn while-do into do-while, for clarity.
22535 * keyboard.c (syms_of_keyboard): Use the same style as later
22536 in this function when indexing through an array. This also
22537 works around GCC bug 48267.
22539 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22541 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22543 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22544 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22546 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22547 This avoids undefined behavior on integer overflow, and is a bit
22548 more convenient anyway since it is compared to a size_t variable.
22550 Variadic C functions now count arguments with size_t, not int.
22551 This avoids an unnecessary limitation on 64-bit machines, which
22552 caused (substring ...) to crash on large vectors (Bug#8344).
22553 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22554 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
22555 All variadic functions and their callers changed accordingly.

22562 * fns.c (concat): Likewise.
22563 * frame.c (x_set_frame_parameters): Likewise.
22564 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22565 0 if not found, not -1. All callers changed.
22567 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22568 (stack_copy_size): Now size_t, not int.
22569 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22571 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22573 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
22574 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22575 All callers changed.
22577 * lisp.h (multibyte_char_to_unibyte):
22578 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22579 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22580 * character.h (CHAR_TO_BYTE8):
22581 * cmds.c (internal_self_insert):
22582 * editfns.c (general_insert_function):
22583 * keymap.c (push_key_description):
22584 * search.c (Freplace_match):
22585 * xdisp.c (message_dolog, set_message_1): All callers changed.
22587 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
22589 * keyboard.c (safe_run_hook_funcall): New function.
22590 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22591 don't set the hook to nil, but remove the offending function instead.
22592 (Qcommand_hook_internal): Remove, unused.
22593 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define

22775 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22777 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22778 unconditionally since it does the check itself.
22780 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22782 Fix more problems found by GCC 4.5.2's static checks.
22784 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22785 the first time through the loop, since we know p0 < p1 then.
22786 This also avoids a gcc -Wstrict-overflow warning.
22788 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22789 leading to a memory leak, possible in functions like
22790 load_charset_map_from_file that can allocate an unbounded number
22791 of objects (Bug#8318).
22793 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22794 that could (at least in theory) be that large.
22796 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22797 This is less likely to overflow, and avoids undefined behavior if
22798 overflow does occur. All callers changed. Use strtoul to scan
22799 for the unsigned long integer.

22816 * process.c (Fmake_network_process): Use socklen_t, not int,
22817 where POSIX says socklen_t is required in portable programs.
22818 This fixes a porting bug on hosts like 64-bit HP-UX, where
22819 socklen_t is wider than int (Bug#8277).
22820 (Fmake_network_process, server_accept_connection):
22821 (wait_reading_process_output, read_process_output):
22824 * process.c: Rename or move locals to avoid shadowing.

22834 Make tparam.h and terminfo.c consistent.
22835 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22836 Include tparam.h instead, since it declares them.
22837 * cm.h (PC): Remove extern decl; tparam.h now does this.
22838 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22839 * terminfo.c: Include tparam.h, to check interfaces.
22840 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22841 (tparam): Adjust signature to match interface in tparam.h;
22842 this removes some undefined behavior. Check that outstring and len
22843 are zero, which they always are with Emacs.
22844 * tparam.h (PC, BC, UP): New extern decls.
22846 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22847 (xftfont_open): Rename locals to avoid shadowing.

22865 (composition_update_it): Mark var as initialized.
22866 (find_automatic_composition): Mark vars as initialized,
22867 with a FIXME (Bug#8290).

22873 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22874 to avoid shadowing.

22886 Fix pointer signedness.
22887 (alsa_choose_format): Remove unused local var.
22888 (wav_play): Initialize a variable to 0, to prevent undefined
22889 behavior (Bug#8278).
22891 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22893 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22895 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22896 clobbering (Bug#8298).
22897 * sysdep.c (sys_subshell): Likewise.
22898 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22900 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22901 This should get cleaned up, so that child_setup has the
22902 same signature on all platforms.
22904 * callproc.c (call_process_cleanup): Now static.
22905 (relocate_fd): Rename locals to avoid shadowing.
22907 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22909 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22910 not to be necessary, and produces flickering.
22912 2011-03-20 Glenn Morris <rgm@gnu.org>
22914 * config.in: Remove file.
22916 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

22966 n rather than nn, a way that does not involve shadowing.
22967 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
22969 * deps.mk (unexalpha.o): Remove; unused.

23048 * data.c (Findirect_variable): Name an expression, to avoid
23049 gcc -Wbad-function-cast warning.
23050 (default_value, arithcompare, arith_driver, arith_error): Now static.

23065 (GC_STRING_CHARS): Remove; not used.
23066 (Fmemory_limit): Cast sbrk's returned value to char *.
23068 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
23069 avoids undefined behavior in theory.
23071 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
23073 Use functions, not macros, for up- and down-casing (Bug#8254).
23074 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23075 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23076 to use the following functions instead of these macros.
23077 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23078 EMACS_INT, since callers assume the returned value fits in int.
23079 (upcase1): Likewise, for UPCASE_TABLE.
23080 (uppercasep, lowercasep, upcase): New static inline functions.
23081 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
23082 the race-condition problem in the old DOWNCASE.
23084 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):

23090 which gcc can warn about.
23091 (regex_compile, re_match_2_internal): Mark locals as initialized.
23092 (RETALLOC_IF): Define only if needed.
23093 (WORDCHAR_P): Likewise. This one is never needed, but is used
23094 only in a comment talking about a compiler bug, so put inside
23095 the #if 0 of that comment.
23096 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23097 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
23100 * search.c (boyer_moore): Rename locals to avoid shadowing.

23123 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23124 New macros, so that the caller can use some names other than
23125 gcpro1, gcpro2, etc.
23126 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23128 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23129 argument, for consistency with GCPRO2_VAR, etc: it is now the
23130 prefix of the variable, not the variable itself. All uses
23132 * dired.c (directory_files_internal, file_name_completion):
23133 Rename locals to avoid shadowing.
23135 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23136 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23137 dired.c's scmp function, had undefined behavior.
23138 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23139 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23140 * buffer.h: ... to here, because these macros use current_buffer,
23141 and the new implementation with inline functions needs to have
23142 current_buffer in scope now, rather than later when the macros
23144 (downcase, upcase1): New static inline functions.
23145 (DOWNCASE, UPCASE1): Reimplement using these functions.
23146 This avoids undefined behavior in expressions like
23147 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23148 from race conditions in accessing the global variables
23149 case_temp1 and case_temp2.
23150 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23151 * lisp.h (case_temp1, case_temp2): Remove their decls.
23152 * character.h (ASCII_CHAR_P): Move from here ...
23153 * lisp.h: ... to here, so that the inline functions mentioned
23154 above can use them.
23156 * dired.c (directory_files_internal_unwind): Now static.
23158 * fileio.c (file_name_as_directory, directory_file_name):
23159 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
23161 (file_name_as_directory): Use const pointers when appropriate.
23162 (Fexpand_file_name): Likewise. In particular, newdir might
23163 point at constant storage, so make it a const pointer.
23164 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
23165 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23167 (Fset_file_times, Finsert_file_contents, auto_save_error):

23172 to avoid shadowing.
23174 * marker.c (bytepos_to_charpos): Remove; unused.
23176 * lisp.h (verify_bytepos, count_markers): New decls,
23177 so that gcc does not warn that these functions aren't declared.
23179 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
23180 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
23181 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
23182 (copy_text): Remove unused local var.
23184 * filelock.c (within_one_second): Now static.
23185 (lock_file_1): Rename local to avoid shadowing.
23187 * buffer.c (fix_overlays_before): Mark locals as initialized.
23188 (fix_start_end_in_overlays): Likewise. This function should be
23189 simplified by using pointers-to-pointers, but that's a different
23191 (switch_to_buffer_1): Now static.
23192 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
23193 (report_overlay_modification): Rename locals to avoid shadowing.
23195 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
23196 Fix pointer signedness issue.
23197 (sys_subshell): Mark local as volatile if checking for lint,
23198 to suppress a gcc -Wclobbered warning that does not seem to be right.
23199 (MAXPATHLEN): Define only if needed.
23201 * process.c (serial_open, serial_configure): Move decls from here ...
23202 * systty.h: ... to here, so that they can be checked.
23204 * fns.c (get_random, seed_random): Move extern decls from here ...
23205 * lisp.h: ... to here, so that they can be checked.
23207 * sysdep.c (reset_io): Now static.
23208 (wait_for_termination_signal): Remove; unused.
23210 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
23211 (copy_keymap_item, append_key, push_text_char_description):
23213 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
23214 (DENSE_TABLE_SIZE): Remove; unused.
23215 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
23216 (describe_map_tree):
23217 Rename locals to avoid shadowing.
23219 * keyboard.c: Declare functions static if they are not used elsewhere.

23368 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
23369 reports time overflow. See
