41 * w32fns.c (w32_fullscreen_rect): New function to compute the
42 window rectangle for the given fullscreen mode.
43 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
44 longer tunes the window size. This keeps the window's edges flush
45 with the screen and allows the taskbar to hide itself in fullboth.
47 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
48 window decorations and uses the entire screen.
50 * w32term.h (w32_fullscreen_rect) Add prototype.
51 (struct w32_output): Replace normal_width, normal_height,
52 normal_top, and normal_left members with a single normal_placement

84 effect only after a call to set-window-buffer. (Bug#14200)
86 2013-04-13 Eli Zaretskii <eliz@gnu.org>
88 * indent.c (Fvertical_motion): Don't consider display strings on
89 overlay strings as display strings on the buffer position we
90 started from. This prevents vertical cursor motion from jumping
91 more than one line when there's an overlay string with a display
92 property at end of line.
93 Reported by Karl Chen <Karl.Chen@quarl.org> in
94 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

103 * window.c (Fwindow_end): Test more flags, including the buffer's
104 last_overlay_modified flag, to determine whether the window's
105 display is really up-to-date. Prevents the function from
106 returning a stale value. (Bug#14170)
107 (Fwindow_line_height): Fix the test for up-to-date-ness of the
110 2013-04-10 Eli Zaretskii <eliz@gnu.org>
112 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
113 garbaged only if it is not already the top frame on its TTY.
114 This prevents flickering due to constant redrawing of TTY frames when
115 there are GUI frames open in the same session. (Bug#13864)
117 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
119 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead

151 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
152 This bug was introduced by my 2013-02-25 change that simplified
153 data_start configuration. Without this change, on GNU/Linux
154 an Emacs configured with --enable-profiling fails immediately
155 due to a profiler signal.
156 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
157 with these flags. On platforms where special flags are needed
158 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
159 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
160 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
162 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>

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

367 Use contents slot, not buffer, where appropriate.
368 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
369 to avoid deleted windows. Use contents slot instead of buffer.
370 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:
371 * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c:

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

1005 CODING_RESULT_INCONSISTENT_EOL and CODING_RESULT_INSUFFICIENT_MEM.
1006 (toplevel): Remove unused CODING_MODE_INHIBIT_INCONSISTENT_EOL.
1007 (CODING_MODE_LAST_BLOCK, CODING_MODE_SELECTIVE_DISPLAY)
1008 (CODING_MODE_DIRECTION, CODING_MODE_FIXED_DESTINATION)

1020 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
1022 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1023 * sysdep.c (list_system_processes)
1024 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1025 Make it a stub in this case; otherwise the build might fail,
1026 and this code hasn't been tested on such hosts anyway.
1027 Problem reported by Nelson H. F. Beebe in
1028 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1029 and analyzed by Jérémie Courrèges-Anglas in
1030 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1032 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1034 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1035 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1036 (get_visually_first_element, move_it_vertically_backward): Ajust users.

1040 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1042 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1043 * filelock.c: Include <c-ctype.h>.
1044 (MAX_LFINFO): New top-level constant.
1045 (lock_info_type): Remove members pid, boot_time. Add members at,
1046 dot, colon. Change user member to be the entire buffer, not a
1047 pointer. This allows us to handle the case where a foreign
1048 pid or boot time exceeds the local range. All uses changed.
1049 (LINKS_MIGHT_NOT_WORK): New constant.
1050 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1051 (defined_WINDOWSNT): Remove.
1052 (MAKE_LOCK_NAME, file_in_lock_file_name):
1053 Always use .#FILE (not .#-FILE) for the file lock,
1054 even if it is a regular file.
1055 (rename_lock_file): New function.
1056 (create_lock_file): Use it.
1057 (create_lock_file, read_lock_data):
1058 Prefer a symbolic link for the lock file, falling back on a
1059 regular file if symlinks don't work. Do not try to create
1060 symlinks on MS-Windows, due to security hassles. Stick with
1061 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1062 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1063 host may be using a Windowsish file system, and cannot use
1064 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1065 doesn't work. Don't fail merely because of a symlink-contents
1066 length limit in the current file system; fall back on regular
1067 files. Increase the symlink contents length limit to 8 KiB, this
1068 should be big enough for any real use and doesn't crunch the
1070 (create_lock_file, lock_file_1, read_lock_data):
1071 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1072 (lock_file_1): Return error number, not bool. All callers changed.
1073 (ELOOP): New macro, if not already defined.
1074 (read_lock_data): Return size of lock file contents, not Lisp object.
1075 All callers changed. Handle a race condition if some other process
1076 replaces a regular-file lock with a symlink lock or vice versa,
1077 while we're trying to read the lock.
1078 (current_lock_owner): Parse contents more carefully, to help avoid
1079 confusing a regular-file lock with some other application's use
1080 of the file. Check for lock file contents being too long, or
1081 not parsing correctly.
1082 (current_lock_owner, lock_file):
1083 Allow foreign pid and boot times that exceed the local range.
1084 (current_lock_owner, lock_if_free, lock_file):
1085 Simplify allocation of lock file contents.
1086 * w32.c (sys_rename_replace): New function, containing most of
1087 the contents of the old sys_rename.
1088 (sys_rename): Use it.
1089 (fchmod): New dummy function.
1090 * w32.h (sys_rename_replace, fchmod): New decls.
1092 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1094 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1095 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1096 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1097 <dmantipov@yandex.ru>.
1099 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1101 * composite.c (get_composition_id, fill_gstring_header):
1102 Use make_uninit_vector where appropriate.
1103 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1104 * xselect.c (clean_local_selection_data): Likewise.
1106 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1108 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1109 * image.c (imagemagick_load_image): Calculate height and width
1110 after flattening the image, not before.
1112 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1114 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1115 * ftfont.c (ftfont_shape_by_flt): Likewise.
1116 * w32uniscribe.c (uniscribe_shape): Likewise.
1118 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1120 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1121 The old approach, which fell back on DIR/.#FILE.0 through
1122 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1123 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1124 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1125 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1126 because the locking mechanism was never reliable in that case).
1127 This patch fixes this and other bugs discovered by a code
1128 inspection that was prompted by
1129 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1130 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1131 to avoid interoperability problems between the MS-Windows and
1132 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1133 instances of Emacs now ignore each others' locks.
1134 * filelock.c (defined_WINDOWSNT): New constant.
1135 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1136 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1137 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1138 regular files on MS-Windows hosts.
1139 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1140 Use SAFE_ALLOCA to avoid problems with long file names.
1141 (MAX_LFINFO): Now a local constant, not a global macro.
1142 (IS_LOCK_FILE): Remove.
1143 (lock_file_1): Don't inspect errno if symlink call succeeds;
1144 that's not portable.
1145 (lock_file): Document that this function can return if lock
1147 (lock_file): Don't access freed storage.
1149 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

1153 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1155 * textprop.c: Use bool for booleans.
1156 (validate_interval_range, Fadd_text_properties)
1157 (Fremove_text_properties): Prefer bool to int when either works.
1159 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1161 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1162 If the interval tree changes as a side effect of calling
1163 modify_region, re-do processing starting from the call to
1164 validate_interval_range. (Bug#13743)
1166 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1168 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1171 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1173 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1174 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1175 access to the lock file until it is written and closed.
1178 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1180 * callint.c (Qcall_interactively):
1181 * macros.c (Qexecute_kbd_macro):

1190 Minor textprop integer cleanup.
1191 * intervals.h, textprop.c (add_text_properties_from_list):
1192 Return void, not int, since nobody uses the return value.
1193 * textprop.c (validate_plist, add_properties, remove_properties)
1194 (Fadd_text_properties):
1195 Don't assume list length fits in int.

1199 (Fremove_list_of_text_properties, text_property_stickiness):
1200 Use bool for booleans.

1202 (Fremove_list_of_text_properties):
1203 Reindent do-while as per GNU style.

1207 Implement CLASH_DETECTION for MS-Windows.
1209 * filelock.c [WINDOWSNT]: Include w32.h.
1210 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1211 function of that name. Up-case the macro arguments.
1212 (IS_LOCK_FILE): New macro.
1213 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1214 (create_lock_file): New function, with body extracted from
1216 [WINDOWSNT]: Implement lock files by writing a regular file with
1217 the lock information as its contents.
1218 (read_lock_data): New function, on Posix platforms just calls
1220 [WINDOWSNT]: Read the lock info from the file.
1221 (current_lock_owner): Call read_lock_data instead of calling
1222 emacs_readlinkat directly.
1223 (lock_file) [WINDOWSNT]: Run the file name through
1226 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1227 just check if the process by that PID exists.
1229 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1230 also present, as doing so will fail to error out if the file
1233 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1235 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1236 (Fremove_list_of_text_properties): Skip all of the intervals in
1237 the region between START and END that already have resp. don't
1238 have the requested properties, not just the first one.
1239 Add assertions that the loop afterwards always modifies the
1240 properties. (Bug#13743)

1270 * vm-limit.c: Move most of mem-limits.h's contents here.
1271 (data_start): New decl. It's OK if this is approximate,
1272 so simplify-away some unnecessary exactness.
1273 (POINTER): Remove; all uses removed.
1274 (data_space_start): Now char *, to avoid casts.
1275 (exceeds_lisp_ptr): New function, replacing the old

1416 * search.c (compile_pattern, fast_looking_at, search_buffer):
1417 (simple_search, boyer_moore, Freplace_match):
1418 * xdisp.c (c_string_pos, number_of_chars, message_dolog):
1419 (get_overlay_arrow_glyph_row, display_mode_element):
1420 (decode_mode_spec_coding, message3):
1421 * xfaces.c (face_at_string_position): Use bool for booleans.
1424 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1426 Fix AIX port (Bug#13650).
1427 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1428 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1429 was #undeffed earlier, so it cannot be used as a macro here.
1430 Use the constant and not the macro.
1432 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1434 * w32proc.c (new_child): If no vacant slots are found in
1435 child_procs[], make another pass looking for slots whose process
1436 has exited or died. (Bug#13546)
1438 * w32.c (sys_pipe): When failing due to file descriptors above
1439 MAXDESC, set errno to EMFILE.
1440 (_sys_read_ahead): Update cp->status when failing to read serial
1441 communications input, so that the status doesn't stay at
1442 STATUS_READ_IN_PROGRESS. (Bug#13546)
1444 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1446 * gtkutil.c (tb_size_cb): New function.
1447 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
1449 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1451 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
1454 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
1456 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1458 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
1460 * font.c (font_range): Add pos_byte argument. Adjust comment
1461 and break long line.
1462 * font.h (font_range): Adjust prototype.
1463 * composite.c (autocmp_chars): Pass byte position to font_range.
1464 Break long line. Remove useless prototype and format comment.
1466 2013-02-13 Glenn Morris <rgm@gnu.org>
1468 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1470 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1472 Improve AIX port some more (Bug#13650).
1473 With this, it should be as good as it was in 23.3, though it's
1474 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1475 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1476 * unexaix.c (start_of_text): Remove.
1477 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1478 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1479 (orig_load_scnptr, orig_data_scnptr):
1480 Now off_t, not long, since they are file offsets.
1481 (make_hdr): Use _data, not start_of_data ().
1482 This is the key part of the fix.
1483 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1484 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1486 * pre-crt0.c (data_start): Initialize to 1.
1487 This ports to compilers that optimize the external declaration
1488 'int x = 0;' as if it were 'int x;' to shrink the executable.
1490 Improve AIX port (Bug#13650).
1491 This doesn't fix the bug, but it makes progress: Emacs builds now.
1492 * unexaix.c: Include inttypes.h, stdarg.h.
1493 (report_error, report_error_1): Mark as _Noreturn.
1494 (report_error): Don't report the wrong errno.
1495 (report_error_1): Now varargs. All callers changed.
1496 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1497 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1498 (write_ptr): Use %p to print address rather than %lx and a cast
1499 to unsigned long. Grow buffer a bit, to be safer.
1501 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1503 * bidi.c (bidi_resolve_neutral): After finding the next
1504 non-neutral character, accept NEUTRAL_ON type as well, because
1505 directional control characters, such as LRE and RLE, have their
1506 type converted to that by bidi_resolve_weak. This avoids aborts
1507 when LRE/RLE follows a run of neutrals.
1508 (bidi_move_to_visually_next): Assert that return value of
1509 bidi_peek_at_next_level is non-negative. Negative values will
1512 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1514 Minor getenv-related fixes.
1515 * callproc.c (Fcall_process_region) [!DOS_NT]:
1516 Avoid unnecessary duplicate call to getenv.
1517 * callproc.c (init_callproc):
1518 * dispnew.c (init_display):
1519 * sysdep.c (sys_subshell):
1520 Omit unnecessary cast of getenv or egetenv.
1522 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1524 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1525 Update dependencies.
1527 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1529 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1531 (display_line): Set w->region_showing to the value of
1532 it->region_beg_charpos, not to -1. This fixes redisplay
1533 optimization when cursor is moved up after M->. (Bug#13623)
1535 (try_scrolling): Scroll text up more if point is too close to ZV
1536 and inside the scroll margin. This makes sure point is moved
1537 outside the scroll margin in these cases.
1539 * window.h (struct window): region_showing can no longer be
1542 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1544 Tune by using memchr and memrchr.
1545 * doc.c (Fsnarf_documentation):
1546 * fileio.c (Fsubstitute_in_file_name):
1547 * search.c (find_newline, scan_newline):
1548 * xdisp.c (pos_visible_p, display_count_lines):
1549 Use memchr and memrchr rather than scanning byte-by-byte.
1550 * search.c (find_newline): Rename from scan_buffer.
1551 Omit first arg TARGET, as it's always '\n'. All callers changed.
1553 Clean up read_key_sequence a tiny bit more.
1554 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1555 (read_key_sequence): Remove unused locals.
1557 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1559 Clean up read_key_sequence a bit; reread active keymaps after first event.
1560 * keyboard.c (read_char, read_char_x_menu_prompt)
1561 (read_char_minibuf_menu_prompt):
1562 Replace nmaps+maps with a single `map' arg.
1563 (follow_key): Operate on a single map.
1564 (active_maps): New function.
1565 (test_undefined): Also return true for nil bindings.
1566 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1567 a single (composed) keymap. Remember `first_event' to choose the right
1568 set of active keymaps. Recompute the set of keymaps after receiving
1569 the first event. Remove GOBBLE_FIRST_EVENT.
1570 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1571 * keyboard.h (read_char): Update declaration.
1572 * lread.c (read_filtered_event): Adjust call to read_char.
1574 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1576 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1577 Don't use the limitation on backwards movement when lines are truncated
1578 in the window. (Bug#13675)
1580 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1582 * marker.c (set_marker_internal): If desired position is passed
1583 as a marker, avoid call to buf_charpos_to_bytepos.
1584 * window.c (Fset_window_point): Omit redundant type checking.
1585 (Fset_window_start): Likewise. Format comment.
1586 (window_scroll_pixel_based): Use set_marker_restricted_both
1587 with character and byte positions obtained from an iterator.
1588 (Fset_window_configuration): Use set_marker_restricted_both.
1589 * xdisp.c (message_dolog): Likewise.
1591 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1593 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1594 When text lines are longer than window's screen lines, don't move back
1595 too far. This speeds up some redisplay operations. (Bug#13675)
1597 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1599 * syntax.c (scan_sexps_forward): Fix byte position calculation
1600 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1602 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
1604 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
1605 that was not needed.
1607 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1609 Minor hashing refactoring.
1610 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1611 (sxhash_float): Return EMACS_UINT, for consistency with the other
1613 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1614 non-static inline function and therefore can't use static vars.
1615 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1616 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1617 with the other hash functions.
1619 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1621 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1622 XXXXXX part of the temporary file pattern is not downcased even
1623 when w32-downcase-file-names is non-nil. (Bug#13661)
1625 * xdisp.c (decode_mode_spec): Remove handling of %t.
1627 * msdos.c (careadlinkatcwd): Remove.
1629 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1631 * lread.c (skip_dyn_bytes): New function (bug#12598).
1632 (read1): Use it. Use getc instead of READCHAR to read bytes.
1633 (load_each_byte): Remove. Update users.
1635 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1637 * search.c (scan_buffer): Calculate end byte position just once.

1639 (search_command): Use eassert.
1640 * syntax.c (struct lisp_parse_state): New member location_byte.
1641 (scan_sexps_forward): Record from_byte and avoid redundant
1642 character to byte position calculation ...
1643 (Fparse_partial_sexp): ... here. Break too long line.
1645 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1647 * lisp.h (make_uninit_vector): New function.
1648 * alloc.c (Fvector, Fmake_byte_code):
1649 * ccl.c (Fregister_ccl_program):
1650 * charset.c (Fdefine_charset_internal, define_charset_internal):
1651 * coding.c (make_subsidiaries, Fdefine_coding_system_internal):

1653 * font.c (Fquery_font, Ffont_info, syms_of_font):
1654 * fontset.c (FONT_DEF_NEW, Fset_fontset_font):
1655 * ftfont.c (ftfont_shape_by_flt):

1660 * window.c (Fcurrent_window_configuration):
1661 * xfaces.c (Fx_family_fonts):
1662 * xselect.c (selection_data_to_lisp_data): Use it.
1664 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
1666 * coding.c (Fdefine_coding_system_internal): Use AREF where
1667 argument is known to be a vector.
1668 * fns.c (Flocale_info): Likewise for ASET.
1669 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1670 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1672 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1674 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1677 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
1678 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
1679 updateCollectionBehaviour.
1681 * nsterm.m (NEW_STYLE_FS): Remove.
1682 (ns_last_use_native_fullscreen): New variable.
1683 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
1684 (x_set_window_size): Do not take title bar and tool bar into account
1685 if isFullscreen returns YES.
1686 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1687 (check_native_fs): New function.
1688 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
1689 (ns_term_init): Remove NEW_STYLE_FS.
1690 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
1691 and tool bar if isFullscreen returns NO.
1692 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
1693 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
1694 with HAVE_NATIVE_FS.
1695 (window:willUseFullScreenPresentationOptions:): New method.
1696 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
1697 Hide toolbar if not enabled (Bug#13444).
1698 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
1699 Restore tool bar if enabled, hide it otherwise (Bug#13444).
1700 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
1701 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
1702 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
1703 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
1704 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1705 (syms_of_nsterm): Add ns-use-native-fullscreen.
1707 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1709 * fileio.c (Qchoose_write_coding_system): Now static.
1711 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1713 * xdisp.c (window_buffer_changed): region_showing can be negative,
1714 which still means region is being displayed.
1715 (redisplay_internal): Resurrect code that forced redisplay of the
1716 whole window when showing region and the mark has changed.
1717 Record the new mark position to allow redisplay optimizations.
1718 (display_line): If it->region_beg_charpos is non-zero, set the
1719 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1721 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1722 not bitfield of 1 bit.
1724 2013-02-03 Daniel Colascione <dancol@dancol.org>
1726 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1727 daemon mode works on cygw32 when Emacs is installed and not just
1730 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1732 Avoid file time stamp bug on MS-Windows (Bug#13149).
1733 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1734 as FAT32 doesn't update time stamps when truncating them.
1735 Also, check that a file time stamp is not a multiple of 100 ns;
1736 this should catch all instances of the problem on MS-Windows,
1737 as its native file system resolution is 100 ns or worse, and
1738 checking for a non-multiple of 100 ns should impose only a small
1739 overhead on systems with ns resolution.
1741 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1743 Avoid encoding file names on MS-Windows when they need to be run
1744 through dostounix_filename.
1745 * w32.c (normalize_filename): Accept an additional argument
1746 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1747 downcase it even if w32-downcase-file-names is non-nil.
1748 (dostounix_filename): Accept an additional argument MULTIBYTE and
1749 pass it to normalize_filename.
1750 (emacs_root_dir): Adjust.
1752 * msdos.h (dostounix_filename): Adjust prototype.
1754 * w32.h (dostounix_filename): Adjust prototype.
1756 * msdos.c (dostounix_filename): Accept an additional argument and
1758 (init_environment): Adjust callers of dostounix_filename.
1760 * fileio.c (Ffile_name_directory, file_name_as_directory)
1761 (directory_file_name, Fexpand_file_name)
1762 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1764 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1766 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1767 variables, as egetenv is case-insensitive for DOS_NT.
1769 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1770 with an encoded file name.
1772 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1773 Adjust calls to dostounix_filename.
1775 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1777 * unexw32.c (unexec): Adjust call to dostounix_filename.
1779 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1781 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1784 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1787 * callproc.c (Fcall_process): Make sure program name in PATH and
1788 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1789 is passed to exec/spawnve, which fails unless the file-name
1792 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1793 even if w32-quote-process-args is nil.
1795 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1797 Fix timestamp bug when write-region appends nothing (Bug#13149).
1798 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1799 the file's time stamp doesn't change if Emacs happens to write nothing
1800 to the file, and on a buggy file system this could cause Emacs to
1801 incorrectly infer that the file system doesn't have the bug.
1802 Avoid this problem by inhibiting the inference in this case.
1804 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1806 * window.h (struct window): Convert base_line_number, base_line_pos
1807 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1808 Convert region_showing member from Lisp_Object to bitfield.
1809 Remove sequence_number member. Adjust comments.
1810 * window.c (sequence_number): Remove.
1811 (make_window): Initialize column_number_displayed.
1812 * print.c (print_object): Follow the printed representation of
1813 frames and print window pointer to distinguish between windows.
1814 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1815 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1816 (wset_column_number_displayed, wset_region_showing): Remove.
1817 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1818 (try_scrolling, try_cursor_movement, redisplay_window)
1819 (try_window_reusing_current_matrix, try_window_id, display_line)
1820 (display_mode_lines, decode_mode_spec): Adjust users.
1821 * .gdbinit (pwinx): Do not print sequence_number.
1823 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1825 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1826 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1827 * dired.c: Include <fcntl.h>.
1828 (open_directory): New function, which uses open and fdopendir
1829 rather than opendir. DOS_NT platforms still use opendir, though.
1830 (directory_files_internal, file_name_completion): Use it.
1831 (file_attributes): New function, with most of the old Ffile_attributes.
1832 (directory_files_internal, Ffile_attributes): Use it.
1833 (file_attributes, file_name_completion_stat): First arg is now fd,
1834 not dir name. All uses changed. Use fstatat rather than lstat +
1836 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1837 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1838 (emacs_readlinkat): New function, with much of the old
1839 Ffile_symlink_p, but with an fd argument for speed.
1840 It uses readlinkat rather than careadlinkatcwd, so that it
1841 need not assume the working directory.
1842 (Ffile_symlink_p): Use it.
1843 * filelock.c (current_lock_owner): Use emacs_readlinkat
1844 rather than emacs_readlink.
1845 * lisp.h (emacs_readlinkat): New decl.
1846 (READLINK_BUFSIZE, emacs_readlink): Remove.
1847 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1848 (emacs_norealloc_allocator, emacs_readlink): Remove.
1849 This stuff is moved to fileio.c.
1850 * w32.c (fstatat, readlinkat): New functions.
1851 (careadlinkat): Don't check that fd == AT_FDCWD.
1852 (careadlinkatcwd): Remove; no longer needed.
1854 2013-01-31 Glenn Morris <rgm@gnu.org>
1856 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
1857 (Fwrite_region): Update for new choose_write_coding_system args.
1858 Move the last piece of choose_write_coding_system here. (Bug#13522)
1859 (syms_of_fileio): Add choose-write-coding-system.
1861 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1863 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1864 (sys_close): Zero out the flags for the file descriptor before
1865 closing it. (Bug#13546)
1867 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1868 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1869 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1872 * w32.c (w32_get_long_filename, init_environment, readlink):
1873 Support file names encoded in DBCS codepages.
1874 (readlink): Use the current file-name-coding-system, not the ANSI
1875 codepage, to decode and handle targets of symlinks.
1877 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1879 * w32.c (opendir): Now accepts a 'const char *'.

1883 Remove obsolete redisplay code. See the discussion at
1884 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1885 * dispnew.c (preemption_period, preemption_next_check): Remove.
1886 (Vredisplay_preemption_period): Likewise.
1887 (update_frame, update_single_window, update_window, update_frame_1):
1888 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1889 used, following the 2012-06-22 change.
1891 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1893 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1895 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1897 * font.c (num_fonts): Remove the leftover from old
1898 debugging code. Adjust comment style here and there.
1899 * insdel.c (insert_1): Remove.
1900 * lisp.h (insert_1): Remove prototype.

1903 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1905 * w32.c (max_filename_mbslen): New function.
1906 (normalize_filename, readdir): Use it to detect locales where ANSI
1907 encoding of file names uses a double-byte character set (DBCS).
1908 If a DBCS encoding is used, advance by characters using
1909 CharNextExA, instead of incrementing a 'char *' pointer.
1910 Use _mbslwr instead of _strlwr. (Bug#13515)
1912 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1913 request of memory reservation to 1.7GB. (Bug#13065)
1915 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1917 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1918 at check_extra_latin label. (Bug#13505)
1920 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1922 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1923 Avoid redundant calls to strlen.
1925 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1927 Drop async_visible and async_iconified fields of struct frame.
1928 This is possible because async input is gone; for details, see
1929 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1930 * frame.h (struct frame): Remove async_visible and async_iconified
1931 members, convert garbaged to unsigned bitfield. Adjust comments.
1932 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1933 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1934 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1935 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1936 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1938 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1939 properly. Likewise for obscured.
1941 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1944 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1946 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1948 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1949 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1951 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1953 * xdisp.c (message2, message2_nolog): Remove functions.
1954 (message3, message3_nolog): Extract nbytes and multibyteness directly
1955 from the string. Change all callers.
1956 (message3_nolog): Don't set message_enable_multibyte since set_message
1957 will reset it anyway.
1958 (message1, message1_nolog): Use message3.
1959 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1960 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1961 (set_message): Drop all but the second arg, which has to be a string.
1962 (set_message_1): Simplify now that we know that a1 is NULL and the
1963 second arg is a string.
1964 * frame.h (struct frame): Remove `message_buf' field.
1965 Use glyphs_initialized_p instead.
1966 (FRAME_MESSAGE_BUF): Remove macro.
1967 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1968 * lisp.h (message2, message2_nolog): Remove declarations.
1969 (message3, message3_nolog): Update declarations.
1970 * keyboard.c (read_char_minibuf_menu_text)
1971 (read_char_minibuf_menu_width): Remove vars.
1972 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1973 to correctly handle multibyte strings.
1974 * frame.c (delete_frame): Don't free message_buf any more.
1975 * editfns.c (message_text, message_length): Remove vars.
1976 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1977 * fileio.c (auto_save_error): Use message3 instead of message2.
1978 * dispnew.c (adjust_frame_message_buffer): Remove function.
1980 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1982 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1983 real estate used for the tool bar and the menu bar.
1985 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1987 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1988 hidden buffer is prepared to modification (Bug#13164).
1990 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1992 * window.h (struct window): Change window_end_valid member from
1993 Lisp_Object to a bitfield. Adjust comments.
1994 (wset_window_end_valid): Remove.
1995 * window.c (adjust_window_count): Clear window_end_valid.
1996 (Fwindow_end): Adjust user. Remove ancient #if 0 code.

1999 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2000 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2001 * xdisp.c (check_window_end, reconsider_clip_changes)
2002 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2003 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2004 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2006 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2008 * xdisp.c (mark_window_display_accurate): Simplify the loop
2009 assuming that the only one of vchild, hchild or buffer window
2010 slots is non-nil. Call mark_window_display_accurate_1 for
2011 the leaf windows only.
2012 (mark_window_display_accurate_1): Always assume leaf window.
2015 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2017 * emacs.c (Qkill_emacs_hook): Now static.
2019 * fileio.c (Finsert_file_contents): Simplify.
2020 Remove unnecessary assignments and tests.
2022 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2024 * w32.c (acl_set_file): Don't test for errors unless
2025 set_file_security returns FALSE. Avoids spurious errors when
2028 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2030 * fileio.c (Finsert_file_contents): Revert code introduced at
2031 2013-01-18 in favor of the simpler and generally better fix.
2032 Save stack space by removing 'buffer' and reusing 'read_buf'
2035 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2037 * lisp.h (eabs): Define unconditionally (Bug#13419).
2038 The old "#if !defined (eabs)" was an unnecessary revenant of back
2039 when this macro was called "abs". Document 'eabs' better.
2041 2013-01-19 Glenn Morris <rgm@gnu.org>
2043 * fns.c (Frandom): Doc fix.
2045 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2047 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2048 segfault when there are lots of overlays.
2050 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2051 when there are lots of overlays.
2052 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2053 for the details and a way to reproduce.
2055 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2057 * fileio.c: Use O_APPEND to append.
2058 This corresponds better to the natural interpretation of "append",
2059 and avoids the need to open the output file twice, or to invoke
2060 lseek when APPEND is neither nil nor a number.
2061 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2062 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2063 file possibly twice, and lseeking to its end; this avoids the
2064 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2065 at the same time: the combination is never needed and apparently
2066 it doesn't work with DOS_NT.
2068 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2069 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2071 Allow floating-point file offsets.
2072 Problem reported by Vitalie Spinu in
2073 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2074 * fileio.c (emacs_lseek): Remove.
2075 (file_offset): New function.
2076 (Finsert_file_contents, Fwrite_region): Use it.
2078 2013-01-19 Chong Yidong <cyd@gnu.org>
2080 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2081 aborting on Fsignal (Bug#13289).
2083 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2085 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2086 set_file_security as failure due to insufficient privileges.
2087 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2088 (fstat): Return owner and group like 'stat' and 'lstat' do.
2090 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2092 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2093 The bug was observed on Ubuntu operating inside a virtual machine,
2094 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2095 The workaround introduces a race condition on non-buggy hosts,
2096 but it's an unlikely race and anyway there's a nearly identical
2097 nearby race that can't be fixed.
2098 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2100 (Fwrite_region): Test for file system time stamp bug.
2101 (init_fileio): New function.
2102 * lisp.h (init_fileio): Declare it.
2103 * emacs.c (main): Call it.
2105 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2106 and make it more consistent with other stat-failure diagnostics.
2108 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2110 Fix crash when inserting data from non-regular files.
2111 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2112 for the error description produced by valgrind.
2113 * fileio.c (read_non_regular): Rename to read_contents.
2114 Free Lisp_Save_Value object used to pass parameters.
2115 (read_non_regular_quit): Rename to read_contents_quit.
2116 (Finsert_file_contents): Redesign internal file reading loop to adjust
2117 gap and end positions after each read and so help make_gap to work
2118 properly. Do not signal an I/O error too early and so do not leave
2119 not yet decoded characters in a buffer, which was the reason of
2120 redisplay crash. Use list2 to build return value. Adjust comments.
2122 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2124 Close a race when statting and reading files (Bug#13149).
2125 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2126 This avoids a race if the file is renamed between stat and open.
2127 This race is not the problem originally noted in Bug#13149;
2128 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2130 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

2136 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
2137 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2138 * alloc.c (format_save_value): Rename to make_save_value.
2139 (make_save_pointer): New function.
2140 (record_xmalloc): Use make_save_pointer.
2141 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2142 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2143 Change users of make_save_value to make_save_pointer.
2144 Likewise for format_save_value and make_save_value.

2153 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
2155 * alloc.c (free_save_value): Now static.
2157 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2159 * keymap.c (map_keymap_internal): Use format_save_value.
2160 (map_keymap_char_table_item): Adjust accordingly.
2161 * fileio.c (non_regular_fd, non_regular_inserted)
2162 (non_regular_nbytes): Remove.
2163 (Finsert_file_contents): Convert trytry to ptrdiff_t.
2164 Use format_save_value to pass parameters to read_non_regular.
2165 (read_non_regular): Use XSAVE_ macros to extract parameters.
2167 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
2169 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
2171 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2173 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2174 extraction from any Lisp_Save_Value slot. Add type checking.
2175 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
2176 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
2177 * xselect.c: All users changed.
2179 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

2190 (save_excursion_restore): Use XSAVE_OBJECT.
2192 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
2194 Avoid needless casts with XSAVE_POINTER.
2195 * alloc.c (mark_object) [GC_MARK_STACK]:
2196 * dired.c (directory_files_internal_unwind):
2197 * fileio.c (do_auto_save_unwind):
2198 * gtkutil.c (pop_down_dialog):
2199 * keymap.c (map_keymap_char_table_item):
2200 * lread.c (load_unwind):
2201 * nsmenu.m (pop_down_menu):
2202 * print.c (print_object) [GC_MARK_STACK]:
2203 * xfns.c (clean_up_file_dialog):
2204 * xmenu.c (cleanup_widget_value_tree):
2205 Omit casts between XSAVE_POINTER and a pointer type.
2207 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2209 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
2210 * eval.c (eval_sub): Protect `form' from being GCed before its
2211 car and cdr becomes protected with the backtrace entry.
2213 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2215 Make Lisp_Save_Value more versatile storage for up to four objects.
2216 * lisp.h (toplevel): Enumeration to describe types of saved objects.
2217 (struct Lisp_Save_Value): New layout. Adjust comments.
2218 (XSAVE_POINTER): New macro.
2219 (XSAVE_INTEGER): Likewise.
2220 (allocate_misc): Add prototype.
2221 (free_misc): Likewise.
2222 * alloc.c (allocate_misc): Now global.
2223 (free_misc): Likewise. Adjust comment.
2224 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
2225 (free_save_value): Likewise.
2226 (mark_object): Likewise.
2227 * editfns.c (save_excursion_save): Pack everything within
2228 Lisp_Save_Value and so avoid xmalloc.
2229 (save_excursion_restore): Adjust to match new layout. Use free_misc
2230 because we do not allocate extra memory any more. Add eassert.
2231 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2232 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
2233 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
2234 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

2244 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
2246 Fix SIGDANGER handlers, for AIX (Bug#13408).
2247 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
2248 Move handlers here from emacs.c; they were out of place.
2250 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
2252 * xterm.c (syms_of_xterm): Adjust documentation for

2282 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>
2284 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
2285 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
2286 Clear tzvalbuf_in_environ if this workaround is in effect.
2287 Problem and fix reported by Kazuhiro Ito.
2289 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>
2291 * insdel.c (Fcombine_after_change_execute, syms_of_insdel):

2295 doc string cross-reference(s).
2297 * window.c (Fwindow_point, syms_of_window): Fix ambiguous doc
2298 string cross-reference(s).
2300 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
2302 Avoid unnecessary byte position calculation for the gap movement.
2303 Since all users of move_gap do CHAR_TO_BYTE for other purposes
2304 anyway, all of them should use move_gap_both instead.
2305 * lisp.h (move_gap): Remove prototype.
2306 * insdel.c (move_gap): Remove.
2307 (move_gap_both): Add eassert.
2308 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.

2316 * term.c (init_tty): Use them instead of rolling our own code.
2317 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
2318 switches from 'signal' to 'pthread_sigmask', which is safer in
2319 multithreaded applications.
2320 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
2321 which has already arranged for that.
2322 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
2323 This is the main part of the bug fix.

2335 predicate, which is how it's really used now. Adjust comment.
2336 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
2337 * buffer.c (buffer_slot_type_mismatch): Remove.
2338 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

2342 left-margin-width, right-margin-width, left-fringe-width,
2343 right-fringe-width, scroll-bar-width and buffer-display-count.
2344 Use Qstringp for default-directory, buffer-file-name,
2345 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
2346 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for

2364 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
2365 (make_gap_1): New function to adjust the gap of any buffer.
2366 * coding.c (coding_alloc_by_making_gap): Use it.
2367 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
2368 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.

2391 trailing dash is properly added.
2393 2013-01-05 Eli Zaretskii <eliz@gnu.org>
2395 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
2396 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
2397 digits for buffer positions, before misalignment starts.
2398 Display "0" for integer "object" field.
2399 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2400 Display the newline glyph more unambiguously.
2402 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2404 * nsterm.m (ns_draw_underwave):
2405 * w32term.c (w32_draw_underwave):
2406 * xterm.c (x_draw_underwave): Make underwave look more triangular
2407 and also degrade gracefully for small fonts. (Bug#13000)
2409 * nsterm.m (ns_draw_text_decoration):
2410 * w32term.c (x_draw_glyph_string):
2411 * xterm.c (x_draw_glyph_string): Don't use previous underline
2412 thickness and position if previous underline type is underwave.
2414 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
2416 * fileio.c (Ffile_acl): Undocument return format.
2418 2013-01-02 Glenn Morris <rgm@gnu.org>
2420 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

2430 * lread.c (read_list):
2431 * minibuf.c (Ftry_completion):
2432 * term.c (tty_ins_del_lines):
2433 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2434 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2436 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2438 * w32.c (unsetenv): Set up the string passed to _putenv
2440 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
2441 for the bug this caused.
2443 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
2445 * coding.c (Qmac): Now static.
2447 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2449 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
2450 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

2454 (update_frame_tool_bar): Check toolbar_is_packed for packing.
2455 Show all on TOOLBAR_TOP_WIDGET.

2458 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
2459 Check toolbar_is_packed.
2460 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on

2462 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
2464 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2465 (xg_update_menubar): Update title only if
2466 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2467 (xg_update_submenu): Skip tearoff only if
2468 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2469 (xg_initialize): Initialize xg_detached_menus only if
2470 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2472 * xterm.h (struct x_output): Surround handlebox_widget with
2473 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2474 toolbar_in_hbox is bool.
2476 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2478 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2479 (LIBS_GNUSTEP): Define.
2480 (LIBES): Add $(LIBS_GNUSTEP).

2483 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2485 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2486 continuation glyph on a TTY with an indication of an empty line.
2489 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2491 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2492 file's SELinux context or ACLs successfully set, nil otherwise.
2494 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.

2497 SetEvent and WaitForSingleObject.
2499 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2501 Port EXTERNALLY_VISIBLE to Clang 3.2.
2502 * conf_post.h (__has_attribute): New macro.
2503 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2505 2012-12-27 Glenn Morris <rgm@gnu.org>
2507 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2508 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2510 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2512 * fileio.c (file_name_as_directory, directory_file_name):
2513 Accept an additional argument MULTIBYTE to indicate whether the input C
2514 came from a multibyte or a unibyte Lisp string; all callers
2515 adjusted. Don't assume the input string is always multibyte.
2517 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2518 don't ENCODE_FILE them, and return a unibyte string if the input
2520 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2521 don't assume the input strings will always be multibyte. If the
2522 input strings are multibyte, decode strings obtained from C
2525 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2527 * lisp.h (toplevel): Add two notices to the comment about
2528 defining a new Lisp data type.

2532 * alloc.c (valid_lisp_object_p): Adjust comment.
2534 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2536 * keyboard.c (record_asynch_buffer_change): Initialize an event
2537 only if it's really needed.
2538 * frame.h (enum output_method): Remove output_mac member since
2539 it's a leftover from the deleted code.
2540 * frame.c (Fframep): Adjust user here ...
2541 * terminal.c (Fterminal_live_p): ... and here.
2542 * coding.c (Qmac): Now here because it's only used to denote
2543 end-of-line encoding type.
2544 (syms_of_coding): DEFSYM it.
2545 * frame.h (Qmac): Remove duplicated declaration.
2547 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2549 * window.c (select_window_1): Now static, since it's used only here.
2551 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2553 * window.c (window_body_cols): Subtract display margins from the
2554 window body width on TTYs as well. See
2555 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2556 for the original report.
2558 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2560 * xdisp.c (redisplay_window): Remove inner local variable
2561 because the outer shadowed one has the same meaning.
2562 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2564 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2565 (xg_create_tool_bar): Adjust users.
2567 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2569 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2570 * buffer.c (Fget_buffer_create): Use it to set compact field of
2571 struct buffer_text to avoid accessing an uninitialized value
2572 when compact_buffer is called for the first time.
2573 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2574 (Fset_buffer_modified_p): Use buffer_window_count to check
2575 whether the buffer is displayed in some window.
2576 * xdisp.c (message_dolog): Likewise.
2578 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2580 * w32.c (acl_set_file): If setting the file security descriptor
2581 fails, and the new DACL is identical to the existing one, silently
2582 return success. This fixes problems for users backing up their
2583 own files without having the necessary privileges for setting
2584 security descriptors.
2586 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2588 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2589 after WaitForSingleObject returns normally. This expedites reader
2590 thread shutdown when delete_child triggers it.
2591 (reap_subprocess): More accurate commentary for why we call
2592 delete_child only when cp->fd is negative.
2594 * w32.c (sys_close): Do not call delete_child on a subprocess
2595 whose handle is not yet closed. Instead, set its file descriptor
2596 to a negative value, so that reap_subprocess will call
2597 delete_child on that subprocess when its SIGCHLD arrives.
2598 This avoids closing handles used for communications between sys_select
2599 and reader_thread, which doesn't give sys_select a chance to
2600 notice that the process exited and invoke the SIGCHLD handler for
2603 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2605 * nsfns.m (Fns_do_applescript): Run event loop until script has
2606 been executed (Bug#12969).

2614 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2616 * w32term.c (w32fullscreen_hook): New function.
2617 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2619 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2621 * fileio.c (Finsert_file_contents): Doc fix.
2623 * w32proc.c (new_child, delete_child, find_child_pid): For a
2624 subprocess, consider its slot being in use as long as its process
2625 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2626 slot when a new process is started immediately after killing
2627 another one, without waiting enough time for the first process to
2628 be reaped and resources allocated for it be orderly freed.
2630 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2632 2012-12-21 Chong Yidong <cyd@gnu.org>
2634 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2636 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2638 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2640 * w32.c (get_name_and_id): Always pass NULL as the first argument
2641 of lookup_account_sid. Avoids crashes with UNC file names that
2642 refer to DFS domains, not to specific machine names. (Bug#12621)
2643 Remove now unused argument FNAME; all callers changed.
2644 (get_file_owner_and_group): Remove now unused argument FNAME; all
2647 2012-12-21 Chong Yidong <cyd@gnu.org>
2649 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2650 error for invalid chars, don't check for a nil return value.
2652 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2654 Avoid calls to CHAR_TO_BYTE if byte position is known.
2655 * editfns.c (make_buffer_string_both): Use move_gap_both.
2656 (Fbuffer_string): Use make_buffer_string_both.

2659 (buf_bytepos_to_charpos): Likewise.
2660 (charpos_to_bytepos): Remove.
2661 * fileio.c (Finsert_file_contents): Use move_gap_both.
2662 * search.c (Freplace_match): Likewise.
2663 * process.c (process_send_region): Likewise. Use convenient
2664 names for byte positions.
2665 * lisp.h (charpos_to_bytepos): Remove prototype.
2666 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2667 * insdel.c (move_gap): Likewise.

2675 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2676 (redisplay_internal): Don't bother selecting the frame to get the
2677 proper value of frame-local variables (bug#13225).
2679 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2681 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2682 Rename 4th argument since it may be buffer or string. Adjust comment.
2683 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2685 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2687 * coding.c (Fdetect_coding_region): Do not check start and end with
2688 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2689 (code_convert_region): Likewise.
2691 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2693 * w32.c (acl_get_file, acl_set_file): Run the file name through
2694 map_w32_filename, and resolve any symlinks in the file name, like
2696 (acl_set_file): Call revert_to_self, if any privileges were
2699 2012-12-17 Juanma Barranquero <lekktu@gmail.com>

2702 ($(BLD)/w32.$(O)): Update dependencies.
2704 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2706 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2707 propagate redisplay's scrolling (if any) to the right window.
2708 (redisplay_internal): Use ensure_selected_frame.
2709 (display_mode_lines): Complete last fix.
2710 * window.c (select_window_1): New func, extracted from select_window.
2711 (select_window): Use it.
2712 * window.h (select_window_1): Declare.

2738 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2740 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2741 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2742 for some of that bug's symptoms can now cause Emacs to abort.
2743 Remove the workaround.
2744 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2745 The bug that caused SIGCHLD to get lost has been fixed, and the
2746 workaround for it can now cause Emacs to abort.
2748 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2750 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2751 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2752 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

2786 if delete-file succeeds, zero otherwise.
2788 * lisp.h (internal_delete_file): Adjust prototype.
2790 * callproc.c (Fcall_process): Don't overwrite infile with result
2792 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2793 asynchronous subprocess, record the name of the input file name,

2796 delete the file, record it as pending deletion when the subprocess

2807 Fix permissions bugs with setgid directories etc. (Bug#13125)
2808 * dired.c (Ffile_attributes): Return t as the 9th attribute,
2809 to mark it as a placeholder. The old value was often wrong.
2810 The only user of this attribute has been changed to use
2811 file-ownership-preserved-p instead, with its new group arg.
2812 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

2819 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2821 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2822 try to get accurate owner and group information from NT file
2823 security APIs. This is to make most callers of 'stat' and
2824 'lstat', which don't need that information, much faster.
2826 * dired.c (Ffile_attributes) [WINDOWSNT]:
2827 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2828 owner and group information from 'lstat'.
2830 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2832 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2833 as that confuses set-auto-coding, so insist on the head-read
2834 returning the full 1024 bytes. Let lseek compute the tail offset;
2835 less work for us. Do not ignore I/O errors when reading the tail.
2837 * xdisp.c: Minor style fixes.
2838 (init_iterator): Hoist assignment out of if-expression.
2839 (markpos_of_region): Callers now test for sign, not for -1.

2858 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2859 files, fixing a regression from 24.2.
2860 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2862 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2864 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2865 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2866 Remove unnecessary S_ISLNK test, as (contra the comments) this
2867 function can't copy symlinks. Improve quality of error message
2868 when attempting to copy files that are neither regular files nor

2887 * inotify.c (inotify_callback): Generate an Emacs event for every
2888 incoming inotify event.
2890 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2892 * xdisp.c (handle_face_prop): Fix logic of computing
2893 it->start_of_box_run_p.
2894 (append_space_for_newline): If the glyph row is R2L, reset the
2895 iterator's end_of_box_run_p flag before prepending the space glyph.
2896 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2897 iterator's start_of_box_run_p flag before prepending the stretch.

2899 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2900 left_box_line_p and right_box_line_p flags of the glyph for R2L
2901 glyph rows. (Bug#13011)

2908 * window.c (replace_buffer_in_windows_safely): Do nothing
2909 if buffer is not shown in a window.

2915 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
2916 encoded_file_name, which is what it is.
2918 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
2920 Consistently use marker_position and marker_byte_position.

2944 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
2947 * w32fns.c (cache_system_info): Initialize the global hinst
2948 variable here so various initialization calls DTRT.
2950 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
2951 (hinst): Remove unneeded extern declaration.
2952 (_start): Remove initialization of above variables; remove
2953 initialization of hinst, as cache_system_info now does that.

3172 * frame.c (make_frame): Do not set window's buffer to t.
3173 * window.c (Fsplit_window_internal): Likewise. Previously it was
3174 used to indicate that the window is being set up. Now we use

3176 (Fset_window_buffer): ... is always true and can be removed.
3178 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3180 Convenient macro to check whether the buffer is hidden.

3209 New function, containing part of the old call_process_kill.
3210 (call_process_kill): Use it.
3211 This does not change call_process_kill's behavior.
3212 * process.c (Fdelete_process): Use record_kill_process to fix a
3213 race condition that could cause Emacs to lose track of a child.
3215 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>

3224 fails, signal an error instead of continuing with an empty
3226 Encode expanded temp file pattern before passing it to mkstemp or
3229 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3230 Encode the file name before passing it to dostounix_filename, in
3231 case it will downcase it (under w32-downcase-file-names).
3234 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3236 Minor call-process cleanups.
3237 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3238 at the same time as other platforms, to simplify analysis.
3239 No need for fd0_volatile since we have synch_process_fd.

3262 Don't let call-process be a zombie factory (Bug#12980).
3263 Fixing this bug required some cleanup of the signal-handling code.
3264 As a side effect, this change also fixes a longstanding rare race
3265 condition whereby Emacs could mistakenly kill unrelated processes,
3266 and it fixes a bug where a second C-g does not kill a recalcitrant
3267 synchronous process in GNU/Linux and similar platforms.
3268 The patch should also fix the last vestiges of Bug#9488,
3269 a bug which has mostly been fixed on the trunk by other changes.
3270 * callproc.c, process.h (synch_process_alive, synch_process_death)
3271 (synch_process_termsig, sync_process_retcode):
3272 Remove. All uses removed, to simplify analysis and so that
3273 less consing is done inside critical sections.
3274 * callproc.c (call_process_exited): Remove. All uses replaced
3275 with !synch_process_pid.
3276 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3277 These take the role of what used to be in unwind-protect arg.
3279 (block_child_signal, unblock_child_signal):
3280 New functions, to avoid races that could kill innocent-victim processes.
3281 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3282 (call_process_kill): Record killed processes as deleted, so that
3283 zombies do not clutter up the system. Do this inside a critical
3284 section, to avoid a race that would allow the clutter.
3285 (call_process_cleanup): Fix code so that the second C-g works again
3286 on common platforms such as GNU/Linux.
3287 (Fcall_process): Create the child process in a critical section,
3288 to fix a race condition. If creating an asynchronous process,
3289 record it as deleted so that zombies do not clutter up the system.
3290 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3291 light of these changes. Omit unnecessary call to emacs_close
3292 before failure, as the unwind-protect code does that.
3293 * callproc.c (call_process_cleanup):
3294 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3295 * process.c (record_deleted_pid): New function, containing
3296 code refactored out of Fdelete_process.
3297 (Fdelete_process): Use it.
3298 (process_status_retrieved): Remove. All callers changed to use
3299 child_status_change.
3300 (record_child_status_change): Remove, folding its contents into ...
3301 (handle_child_signal): ... this signal handler. Now, this
3302 function is purely a handler for SIGCHLD, and is not called after
3303 a synchronous waitpid returns; the synchronous code is moved to
3304 wait_for_termination. There is no need to worry about reaping
3305 more than one child now.
3306 * sysdep.c (get_child_status, child_status_changed): New functions.
3307 (wait_for_termination): Now takes int * status and bool
3308 interruptible arguments, too. Do not record child status change;
3309 that's now the caller's responsibility. All callers changed.
3310 Reimplement in terms of get_child_status.
3311 (wait_for_termination_1, interruptible_wait_for_termination):
3312 Remove. All callers changed to use wait_for_termination.
3313 * syswait.h: Include <stdbool.h>, for bool.
3314 (record_child_status_change, interruptible_wait_for_termination):
3316 (record_deleted_pid, child_status_changed): New decls.
3317 (wait_for_termination): Adjust to API changes noted above.
3319 * bytecode.c, lisp.h (Qbytecode): Remove.
3320 No longer needed after 2012-11-20 interactive-p changes.
3322 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3324 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3325 the scroll margin, move point outside the margin. (Bug#13055)
3327 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3329 * gtkutil.c (my_log_handler): New function.
3330 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3332 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3334 * lisp.h (modify_region): Rename to...
3335 (modify_region_1): ...new prototype.
3336 * textprop.c (modify_region): Now static. Adjust users.
3337 * insdel.c (modify_region): Rename to...
3338 (modify_region_1): ...new function to work with current buffer.
3339 Adjust comment and users. Use true and false for booleans.
3341 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3343 * alloc.c (free_save_value): New function.
3344 (safe_alloca_unwind): Use it.
3345 * lisp.h (free_save_value): New prototype.
3346 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3348 (save_excursion_restore): Adjust to match saved data structure.
3349 Use free_save_value to offload some work from GC. Drop obsolete
3352 2012-12-03 Chong Yidong <cyd@gnu.org>
3354 * fileio.c (Vauto_save_list_file_name): Doc fix.
3356 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3358 * w32fns.c: Remove prototype of atof.
3359 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3361 (file_dialog_callback): Make it UINT_PTR.
3363 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3366 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3367 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3370 2012-12-03 Glenn Morris <rgm@gnu.org>
3372 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3374 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3376 Fix xpalloc confusion after memory is exhausted.
3377 * alloc.c (xpalloc): Comment fix.
3378 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3379 and signals an error, do not clear charset_table_size, as
3380 charset_table is still valid.
3381 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3383 Use execve to avoid need to munge environ (Bug#13054).
3384 * callproc.c (Fcall_process):
3385 * process.c (create_process):
3386 Don't save and restore environ; no longer needed.
3387 * callproc.c (child_setup):
3388 Use execve, not execvp, to preserve environ.
3390 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3392 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3394 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3396 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3397 display for sliced images (Bug#10500).
3399 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3401 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3403 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3404 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3406 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3408 * xdisp.c (window_outdated): Remove eassert since it hits
3409 some suspicious corner cases (see Bug#13007 and Bug#13012).
3410 (mode_line_update_needed): New function.
3411 (redisplay_internal, redisplay_window): Use it.
3412 (ensure_selected_frame): New function.
3413 (redisplay_internal, unwind_redisplay): Use it.
3414 (redisplay_internal): Move comment about buffer_shared...
3415 (buffer_shared_and_changed): ...near to its real use.
3417 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3419 * callproc.c (Fcall_process): Don't misreport vfork failure.
3421 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3423 * callproc.c (Fcall_process): Fix vfork portability problems.
3424 Do not assume that fd[0], count, filefd, and save_environ survive
3425 vfork. Fix bug whereby wrong errno value could be reported for
3426 pipe failure. Some minor cleanups, too, as follows. Move buf and
3427 bufsize to the context where they're needed. Change new_argv to
3428 be of type char **, as this is more convenient and avoids casts.
3429 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3430 Now local constants, not macros.
3432 2012-11-18 Kenichi Handa <handa@gnu.org>
3434 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3435 for the variable "f".
3437 2012-11-13 Kenichi Handa <handa@gnu.org>
3439 * font.c (font_unparse_xlfd): Exclude special characters from the
3440 generating XLFD name.
3442 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

3466 highlighting on the frame was cleared. Prevents assertion
3467 violations when repeatedly clicking on the "Top" link of the
3468 "bread-crumbs" in Info buffers.

3482 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3483 between bpos_covered and bpos_max. This fixes cursor display when
3484 several display strings follow each other.
3486 * .gdbinit (pgx): If the glyph's object is a string, display the
3487 pointer to string data, rather than the value of the string object
3488 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3490 * indent.c (Fvertical_motion): If the starting position is covered
3491 by a display string, return to one position before that, to avoid
3492 overshooting it inside move_it_to. (Bug#12930)
3494 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3496 * frame.h (struct frame): Remove display_preempted member

3505 Drop unused pending_menu_activation member.
3506 * xterm.h (struct x_output): Drop outdated #if 0 code.
3507 Use bitfields for explicit_parent, asked_for_visible,
3508 has_been_visible and net_wm_state_hidden_seen members.

3512 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3513 of a literal "/". (Bug#12955)
3514 (gl-stamp): Invoke fc.exe directly, not through cmd.

3518 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
3519 * dired.c: Assume HAVE_DIRENT_H.
3520 (NAMLEN): Remove, replacing with ...
3521 (dirent_namelen): New function. All uses changed. Use the GNU macro
3522 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3523 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3524 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3525 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3527 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3528 * ndir.h: Rename to ../nt/inc/dirent.h.
3529 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3530 Do not include <dirent.h>; no longer needed.
3531 * w32.c: Include <dirent.h> rather than "ndir.h".
3533 2012-11-23 Chong Yidong <cyd@gnu.org>
3535 * xftfont.c (xftfont_open): Remove duplicate assignment.
3537 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3539 * alloc.c (Fgarbage_collect): Unblock input after clearing
3540 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3541 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3542 * msdos.c (IT_frame_up_to_date): Use it here...
3543 * w32term.c (w32_frame_up_to_date): ...here...
3544 * xterm.c (XTframe_up_to_date): ...and here...
3545 * nsterm.m (ns_frame_up_to_date): ...but not here.
3546 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3548 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3549 Do not check whether GC is in progress.

3557 'tail' and 'frame' local variables.
3559 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3561 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3562 with Windows system header.
3564 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3566 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3567 * alloc.c: Assume unistd.h exists.

3571 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3572 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3573 * w32.h (getcwd): Remove decl.
3575 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>

3583 * emacs.c (main): Set the G_SLICE environment variable for all
3584 Cygwin builds, not just GTK builds. See
3585 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3587 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3589 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3590 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3591 Define for the MSVC compiler.
3593 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3595 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3596 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3597 dostounix_filename. Prevents crashes down the road, because
3598 dostounix_filename assumes it gets a unibyte string.
3599 Reported by Michel de Ruiter <michel@sentient.nl>, see
3600 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html

3638 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3639 cygwin_convert_file_name*.
3641 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):

3644 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3646 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3648 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3650 * w32select.c: Include w32common.h before w32term.h, so that
3651 windows.h gets included before w32term.h uses some of its
3652 features, see below.
3654 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3656 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

3662 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3663 (ns_select): Return at once if events are held (Bug#12834).
3665 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3667 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3668 Needed following 2012-10-20 change. (Bug#12902)
3670 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3672 * w32proc.c (waitpid): Remove unused label get_result.
3674 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3676 * makefile.w32-in (SYSWAIT_H): New macro.
3677 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3678 ($(BLD)/sysdep.$(O)): Update dependencies.

3684 * emacs.c, term.c (O_RDWR): Remove.
3685 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3686 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3687 * nsterm.m: Assume <fcntl.h> exists.
3688 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3689 (create_pty, Fmake_network_process, server_accept_connection)
3690 (wait_reading_process_output, init_process_emacs):
3692 (wait_reading_process_output): Put in a special case for WINDOWSNT
3693 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3694 It's not clear this is needed, but it's a more-conservative change.
3695 (create_process): Assume FD_CLOEXEC.
3696 (create_process, create_pty): Assume O_NOCTTY.
3697 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3698 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3699 Omit if not DOS_NT, since F_GETFL is not defined there.
3700 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3701 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3703 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3704 lack it, since gnulib guarantees this.
3705 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3707 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3709 * w32.c (faccessat): Pretend that directories have the execute bit
3710 set. Emacs expects that, e.g., in files.el:cd-absolute.
3712 * w32proc.c (create_child): Don't clip the PID of the child
3713 process to fit into an Emacs integer, as this is no longer a
3715 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3716 reaping only the process specified by PID argument, if that is
3717 positive. Use PID instead of dead_child to know which process to
3718 reap. Wait for the child to die only if WNOHANG is not in
3720 (sys_select): Don't set dead_child.
3722 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3723 as it is no longer needed.
3725 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3727 (record_child_status_change): Remove the setting of
3728 record_at_most_one_child for the !WNOHANG case.
3730 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3732 Fix problems in ns port found by static checking.
3733 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3734 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3735 not to process group.
3736 (ns_select): Use emacs_write, not write, as that's more robust
3737 in the presence of signals.
3738 (fd_handler:): Check for read errors.
3740 2012-11-16 Glenn Morris <rgm@gnu.org>
3742 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3744 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3746 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3748 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3750 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3751 use the same value of thread handle.
3752 (start_timer_thread): If the timer thread exited (due to error),
3753 clean up by closing the two handles it used. Duplicate the caller
3754 thread's handle here, so it gets duplicated only once, when
3755 launching the timer thread. Set priority of the timer thread, not
3757 (getitimer): Don't duplicate the caller thread's handle here.
3760 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3762 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3765 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3767 Remove no-longer-used pty_max_bytes variable.
3768 * process.c (pty_max_bytes): Remove; unused.
3769 (send_process): Do not set it.
3771 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3773 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3774 Update dependencies.
3776 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3778 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3779 This follows up on the 2012-09-29 patch that removed indirection
3780 for the 'function' field. Reported by Sergey Vinokurov in
3781 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3783 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3785 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3786 different name, as the MS runtime does not have such a function,
3787 and probably never will.) All callers changed. Ignore DIRFD
3788 value if PATH is an absolute file name, to match Posix spec
3789 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3792 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3794 * xdisp.c (echo_area_display, redisplay_internal):
3795 Omit redundant check whether frame_garbaged is set.
3797 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3799 Use faccessat, not access, when checking file permissions (Bug#12632).
3800 This fixes a bug that has been present in Emacs since its creation.
3801 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3802 which must set some sort of record. (Torek's bug report was against
3803 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3804 same common flaw.) See Torek's Usenet posting
3805 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3806 Posted: Fri Apr 8 14:18:56 1983.
3807 * Makefile.in (LIB_EACCESS): New macro.
3809 * callproc.c (init_callproc):
3810 * charset.c (init_charset):
3811 * fileio.c (check_existing, check_executable, check_writable)
3813 * lread.c (openp, load_path_check):
3814 * process.c (allocate_pty):
3816 Use effective UID when checking permissions, not real UID.
3817 * callproc.c (init_callproc):
3818 * charset.c (init_charset):
3819 * lread.c (load_path_check, init_lread):
3820 Test whether directories are accessible, not merely whether they exist.
3821 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3822 * fileio.c (check_existing, check_executable, check_writable)
3824 Use symbolic names instead of integers for the flags, as they're
3826 (check_writable): New arg AMODE. All uses changed.
3827 Set errno on failure.
3828 (Ffile_readable_p): Use faccessat, not stat + open + close.
3829 (Ffile_writable_p): No need to call check_existing + check_writable.
3830 Just call check_writable and then look at errno. This saves a syscall.
3831 dir should never be nil; replace an unnecessary runtime check
3832 with an eassert. When checking the parent directory of a nonexistent
3833 file, check that the directory is searchable as well as writable, as
3834 we can't create files in unsearchable directories.
3835 (file_directory_p): New function, which uses 'stat' on most platforms
3836 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3837 (Ffile_directory_p, Fset_file_times): Use it.
3838 (file_accessible_directory_p): New function, which uses a single
3839 syscall for efficiency.
3840 (Ffile_accessible_directory_p): Use it.
3841 * xrdb.c (file_p): Use file_directory_p.
3842 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3843 * lread.c (openp): When opening a file, use fstat rather than
3844 stat, as that avoids a permissions race. When not opening a file,
3845 use file_directory_p rather than stat.
3846 (dir_warning): First arg is now a usage string, not a format.
3847 Use errno. All uses changed.
3848 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3849 that merely introduced a race.
3850 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3851 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3852 and similarly for the other O_* flags.
3853 * w32.c (sys_faccessat): Rename from sys_access and switch to
3854 faccessat's API. All uses changed.
3855 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3856 (magic_db): Rename from magic_file_p.
3857 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3858 char *, so that we don't have to test for file existence
3859 separately from opening the file for reading. This removes a race
3860 fixes a permission-checking problem, and simplifies the code.
3862 (file_p): Remove; no longer needed.
3864 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3866 Omit glyphs initialization at startup.
3867 * dispnew.c (glyphs_initialized_initially_p): Remove.
3868 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3869 (Fredraw_frame): Move actual code from here...
3870 (redraw_frame): ...to here. Add eassert. Adjust comment.
3871 (Fredraw_display): Use redraw_frame.
3872 * xdisp.c (clear_garbaged_frames): Likewise.
3874 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3876 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3877 passed to pint2str and pint2hrstr to be at most the size of the
3878 frame's decode_mode_spec_buffer. This avoids crashes with very
3879 large values of FIELD_WIDTH argument to decode_mode_spec.
3882 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3884 Fix a race with verify-visited-file-modtime (Bug#12863).
3885 Since at least 1991 Emacs has ignored an mtime difference of no
3886 more than one second, but my guess is that this was to work around
3887 file system bugs that were fixed long ago. Since the race is
3888 causing problems now, let's remove that code.
3889 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3890 whose time stamp is off by no more than a second. Insist that the
3891 file time stamps match exactly.
3893 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3895 * frame.h (struct frame): Convert external_tool_bar member to
3896 1-bit unsigned bitfield.
3897 * termhooks.h (struct terminal): Remove mouse_moved member since
3898 all users are long dead. Adjust comment on mouse_position_hook.
3900 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3902 Simplify by using FOR_EACH_FRAME here and there.
3903 * frame.c (next_frame, prev_frame, other_visible_frames)
3904 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3905 * w32term.c (x_window_to_scroll_bar): Likewise.
3906 * window.c (window_list): Likewise.
3907 * xdisp.c (x_consider_frame_title): Likewise.
3908 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3909 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3910 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3911 * xmenu.c (menubar_id_to_frame): Likewise.
3912 * xselect.c (frame_for_x_selection): Likewise.
3913 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3914 (x_window_to_menu_bar): Likewise.
3915 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3917 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3919 * data.c (Qdefalias_fset_function): Now static.
3921 Another tweak to vectorlike_header change.
3922 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3923 Remove, and replace all uses with ...
3924 (next_in_free_list, set_next_in_free_list):
3925 New functions, which respect C's aliasing rules better.
3927 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3929 * window.c (list4i): Rename from 'quad'. All uses changed.
3930 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3932 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3934 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3935 warning about mixing declarations and code in ISO C90.
3937 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3939 * window.c (Fsplit_window_internal): Set combination limit of
3940 new parent window to t iff Vwindow_combination_limit is t;
3941 fixing a regression introduced with the change from 2012-09-22.
3942 (Fset_window_combination_limit): Fix doc-string.
3944 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3946 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3947 amount when the scroll margins are too large. When scrolling
3948 backwards in the buffer, give up if cannot reach point or the
3949 scroll margin within a reasonable number of screen lines.
3950 Fixes point position in window under scroll-up/down-aggressively when
3951 point is positioned many lines beyond the window top/bottom.
3954 * ralloc.c (relinquish): If real_morecore fails to return memory
3955 to the system, don't crash; instead, leave the last heap
3956 unchanged and return. (Bug#12774)
3958 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3960 * lisp.h (AUTOLOADP): New macro.
3961 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3962 * data.c (Ffset): Remove special ad-advice-info handling.
3963 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3965 (Finteractive_form): Simplify.
3966 (Fquo): Don't insist on having at least 2 arguments.
3967 (Qdefalias_fset_function): New var.
3969 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3971 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
3973 * nsfont.m (Qcondensed, Qexpanded): New variables.
3974 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
3975 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3977 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3979 Fix recently introduced crash on MS-Windows (Bug#12839).
3980 * w32term.h (struct scroll_bar): Use convenient header.
3981 (SCROLL_BAR_VEC_SIZE): Remove.
3982 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3984 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3986 Tweak last vectorlike_header change.
3987 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3988 vectorlike object on the free list. This is introduced to avoid
3989 some (but not all) pointer casting and aliasing problems, see
3990 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3991 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3993 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3995 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3997 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3998 been removed, so remove them here also.
4000 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4002 * doc.c (Fdocumentation): Handle new property
4003 dynamic-docstring-function to replace the old ad-advice-info.
4005 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4007 * fns.c (Qeql, hashtest_eq): Now static.
4009 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4011 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4012 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4013 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
4014 * buffer.c (compare_overlays): Use XLI rather than XHASH.
4016 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
4018 Use same hash function for hashfn_profiler as for hash_string etc.
4019 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
4020 * lisp.h (sxhash_combine): New inline function, with the contents
4021 of the old SXHASH_COMBINE.
4022 * profiler.c (hashfn_profiler): Use it, instead of having a
4023 special hash function containing a comparison that always yields 1.
4025 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4027 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4028 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4029 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4032 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4034 * image.c (xpm_make_color_table_h): Fix compiler error because
4035 make_hash_table changed.
4037 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4039 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4041 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4043 Use ad-hoc comparison function for the profiler's hash-tables.
4044 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4045 (make_log): Use them.
4046 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4047 call Fequal any more.
4048 (Ffunction_equal): New function.
4049 (cmpfn_profiler, hashfn_profiler): New functions.
4050 (syms_of_profiler): Initialize them.
4051 * lisp.h (struct hash_table_test): New struct.

4056 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4057 (hash_lookup, hash_remove_from_table): Move assertion checking of
4058 hashfn result here. Check hash-equality before calling cmpfn.
4059 (Fmake_hash_table): Adjust call to make_hash_table.
4060 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
4061 (syms_of_fns): Initialize them.

4065 * print.c (print_object): Adjust to new hash-table struct.
4066 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
4068 2012-11-08 Eli Zaretskii <eliz@gnu.org>
4070 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4071 value of w32-scroll-lock-modifier is neither nil nor one of the
4072 known key modifiers. (Bug#12806)
4074 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4076 Shrink struct vectorlike_header to the only size field.
4077 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4079 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4080 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4081 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4082 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4083 information from the vector header. Adjust comment.
4084 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
4085 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
4087 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
4088 (struct vectorlike_header): Remove next member. Adjust comment.

4091 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
4092 (sweep_string, lisp_malloc): Remove useless prototypes.
4093 (enum mem_type): Adjust comment.
4094 (NEXT_IN_FREE_LIST): New macro.
4095 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
4096 (Fmake_bool_vector): Likewise.
4097 (struct large_vector): New type to represent allocation unit for
4098 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4099 (large_vectors): Change type to struct large_vector.
4100 (allocate_vector_from_block): Simplify.
4101 (PSEUDOVECTOR_NBYTES): Replace with...
4102 (vector_nbytes): ...new function. Adjust users.
4103 (sweep_vectors): Adjust processing of large vectors.
4104 (allocate_vectorlike): Likewise.
4105 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4106 Add easserts. Adjust XSETPVECTYPESIZE usage.
4107 (allocate_buffer): Use BUFFER_PVEC_INIT.
4108 (live_vector_p): Adjust to match large vector.
4109 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4110 * buffer.h (struct buffer): Add next member.
4111 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4113 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
4114 * fns.c (internal_equal): Adjust to match enum pvec_type change.
4115 (copy_hash_table): Adjust to match vector header change.
4116 * lread.c (defsubr): Use XSETPVECTYPE.
4117 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
4118 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
4119 (xvecsize): New command.
4121 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4123 * keyboard.c (event_to_kboard): Do not dereference
4124 frame_or_window field of SELECTION_REQUEST_EVENT
4125 and SELECTION_CLEAR_EVENT events (Bug#12814).
4126 * xterm.h (struct selection_input_event): Adjust comment.
4128 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4130 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4131 such as Scroll Lock, if the respective keys are treated as
4132 function keys, not as modifiers. This avoids destroying non-ASCII
4133 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4135 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4137 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4139 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4141 Restore some duplicate definitions (Bug#12814).
4142 This undoes part of the 2012-11-03 changes. Some people build
4143 with plain -g rather than with -g3, and they need the duplicate
4144 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4145 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4146 Define as macros, as well as as enums or as constants.
4148 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4150 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4151 to keypad keys (Bug#12816).
4153 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4155 Minor adjustments of recently-changed frame functions.
4156 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4157 known to be a frame (we're in the FRAMEP branch).
4158 * lisp.h (Qframep): Remove decl. frame.h declares this.
4159 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4160 since they're meant for Lisp fixnum values.
4162 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4164 * window.c (Fwindow_combination_limit): Revert to the only
4165 required argument and adjust docstring as suggested in
4166 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html

4169 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4171 Widely used frame validity and checking functions.
4172 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
4173 * frame.c (decode_live_frame, decode_any_frame): New functions.
4174 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
4175 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
4176 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

4183 (frame_buffer_list, frame_buffer_predicate): Remove.
4184 * lisp.h (frame_buffer_predicate): Remove prototype.
4185 * buffer.c (Fother_buffer): Use decode_any_frame.
4186 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4187 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4188 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4189 (Fclose_font, Ffont_info): Use decode_live_frame.
4190 * fontset.c (check_fontset_name): Likewise.
4191 * terminal.c (Fframe_terminal): Likewise.
4192 * w32fns.c (check_x_frame): Likewise.
4193 * window.c (Fminibuffer_window, Fwindow_at)
4194 (Fcurrent_window_configuration): Likewise.

4198 * xfaces.c (frame_or_selected_frame): Remove.
4199 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4200 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)

4202 * xfns.c (check_x_frame): Likewise.
4204 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4206 * window.c (quad): New function.
4207 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4208 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4209 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)

4211 (Fwindow_fringes): Use list3.
4212 (Fwindow_scroll_bars): Use list4.
4213 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4214 (Fwindow_combination_limit): Allow zero number of arguments.
4216 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4218 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4220 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4221 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4222 file descriptor 2 for standard error. (Bug#12805)
4224 2012-11-05 Chong Yidong <cyd@gnu.org>
4226 * process.c (wait_reading_process_output): Revert previous change.
4228 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4230 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4231 This removes code that has been obsolete since around 1990.
4232 * callproc.c (Fcall_process):
4234 * process.c (create_process):
4235 * term.c (dissociate_if_controlling_tty):
4236 Assume setsid exists.
4237 * callproc.c (child_setup): Assume setpgid exists and behaves as
4238 per POSIX.1-1988 or later.
4239 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4240 * emacs.c (shut_down_emacs):
4241 * sysdep.c (sys_suspend, init_foreground_group):
4242 Assume getpgrp behaves as per POSIX.1-1998 or later.
4243 * msdos.c (setpgrp): Remove.
4244 (tcgetpgrp, setpgid, setsid): New functions.
4245 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4246 * term.c (no_controlling_tty): Remove; unused.
4247 * w32proc.c (setpgrp): Remove.
4248 (setsid, tcgetpgrp): New functions.
4250 Simplify by assuming __fpending.
4251 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4252 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4253 Do not assume that __fpending's result fits in int.
4255 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4257 Remove EMACS_OUTQSIZE+sleep hack.
4258 * dispnew.c (update_frame_1): Remove hack for terminals slower
4259 than 2400 bps, which throttled Emacs by having it sleep.
4260 This code hasn't worked since at least 2007, when the multi-tty stuff
4261 was added, and anyway those old terminals are long dead.
4262 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4263 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4265 Fix data-loss with --version (Bug#9574).
4266 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4267 as we can't assume that emacs_strerror is initialized, and strerror
4268 is good enough here.
4269 (main): Invoke atexit earlier, to catch earlier instances of
4270 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4272 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4274 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4275 (keyDown): Remap keypad keys to X11 virtual key codes.
4277 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4279 Fix data-loss with --batch (Bug#9574).
4280 * emacs.c: Include <close-stream.h>.
4281 (close_output_streams): New function.
4282 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4283 and handles errors appropriately.
4284 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4287 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4288 The symptom is a diagnostic "GLib-WARNING **: In call to
4289 g_spawn_sync(), exit status of a child process was requested but
4290 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4291 waitpid(), so exit status can't be returned." The diagnostic
4292 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4293 The real bug is a race condition between Emacs and glib: Emacs
4294 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4295 so that glib can't find it. Work around the bug by invoking
4296 waitpid only on subprocesses that Emacs itself creates.
4297 * process.c (create_process, record_child_status_change):
4298 Don't use special value -1 in pid field, as the caller now must
4299 know the pid rather than having the callee infer it.
4300 The inference was sometimes incorrect anyway, due to another race.
4301 (create_process): Set new 'alive' member if child is created.
4302 (process_status_retrieved): New function.
4303 (record_child_status_change): Use it.
4304 Accept negative 1st argument, which means to wait for the
4305 processes that Emacs already knows about. Move special-case code
4306 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4307 processes that have already been waited for, by testing and
4308 clearing new 'alive' member.
4309 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4310 now does this internally.
4311 (handle_child_signal): Let record_child_status_change do all
4312 the work, since we do not want to reap all exited child processes,
4313 only the child processes that Emacs itself created.
4314 * process.h (Lisp_Process): New boolean member 'alive'.
4316 Omit duplicate definitions no longer needed with gcc -g3.
4317 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4318 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4319 Define only as macros. There's no longer any need to also define
4320 these symbols as enums or as constants, since we now assume
4321 gcc -g3 when debugging.
4323 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4325 * lisp.mk: Adjust comments to the fact that term/internal is now
4326 loaded from loadup.el.
4328 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4329 (msdos_fatal_signal): New function.
4330 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4333 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4334 for GCC versions before 4.
4335 (emacs_raise): Define to call msdos_fatal_signal.
4337 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4338 iterator when starting in the middle of a display or overlay
4341 2012-11-03 Chong Yidong <cyd@gnu.org>
4343 * process.c (wait_reading_process_output): Clean up the last
4346 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4348 * process.c (wait_reading_process_output): Avoid a race condition
4349 with SIGIO delivery (Bug#11536).
4351 2012-11-03 Chong Yidong <cyd@gnu.org>
4353 * buffer.c (cursor_type): Untabify docstring.
4355 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4357 * frame.h (struct frame): Drop can_have_scroll_bars member
4358 which is meaningless for a long time. Adjust comments.
4359 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4360 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4362 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4364 * window.c (decode_next_window_args): Update window arg after
4365 calling decode_live_window and so fix crash reported at
4366 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4367 by Juanma Barranquero <lekktu@gmail.com>.
4368 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4369 * font.c (Ffont_at): Likewise.
4371 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4373 * widget.c (resize_cb): New function.
4374 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4375 (EmacsFrameResize): Check if all is up to date before changing frame
4378 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4380 Implement backtrace output for fatal errors on MS-Windows.
4381 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4382 (BACKTRACE_LIMIT_MAX): New macro.
4383 (w32_backtrace): New function.
4384 (emacs_abort): Use w32_backtrace when the user chooses not to
4385 attach a debugger. Update the text of the abort dialog.
4387 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4389 Window-related stuff cleanup here and there.
4390 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4391 Use decode_any_window.
4392 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4393 * xdisp.c (Fformat_mode_line): Likewise.
4394 * font.c (Ffont_at): Use decode_live_window.
4395 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4396 * window.c (decode_next_window_args): Likewise.
4397 (decode_any_window): Remove static.
4398 * window.h (decode_any_window): Add prototype.
4399 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4400 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4403 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4405 Remove pad from struct input_event.
4406 * termhooks.h (struct input_event): Remove padding field.
4408 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4409 member is never cons for a long time. Adjust comment.
4410 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4411 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4412 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4413 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4415 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4417 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4419 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4421 Fix crash when using Emacs as commit editor for git (Bug#12697).
4422 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4423 and it is configured in conf_post.h.
4424 (Fcall_process): Don't invoke both setsid and setpgid; the former
4425 is enough, if it exists.
4426 * callproc.c (Fcall_process, child_setup):
4427 * process.c (create_process): Use setpgid.
4428 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4430 * dispnew.c (init_display): Initialize the foreground group
4431 if we are running a tty display.
4432 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4433 * lisp.h (init_foreground_group): New decl.
4434 * sysdep.c (inherited_pgroup): New static var.
4435 (init_foreground_group, tcsetpgrp_without_stopping)
4436 (narrow_foreground_group, widen_foreground_group): New functions.
4437 (init_sys_modes): Narrow foreground group.
4438 (reset_sys_modes): Widen foreground group.
4440 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4442 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4444 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4446 * minibuf.c (read_minibuf): Restore current buffer since
4447 choose_minibuf_frame calling Fset_frame_selected_window may
4448 change it (Bug#12766).
4450 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4452 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4454 2012-10-30 Kenichi Handa <handa@gnu.org>
4456 * font.c (Ffont_at): If WINDOW is specified and it is not
4457 displaying the current buffer, signal an error.
4459 2012-10-29 Daniel Colascione <dancol@dancol.org>
4461 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4462 In preparation for fixing bug#12739, move these functions from
4465 * coding.h, coding.c: ... to here, and compile them only when
4466 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4467 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4469 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4471 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4472 (timer_loop, getitimer, setitimer): Use it instead of
4473 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4475 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4478 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4480 * nsterm.m (NO_APPDEFINED_DATA): New define.
4481 (last_appdefined_event_data): New variable
4482 (last_appdefined_event): Remove.
4483 (ns_select): Initialize t from last_appdefined_event_data instead
4484 of [last_appdefined_event data1].
4485 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4486 remove last_appdefined_event (Bug#12698).
4488 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4490 * frame.c (x_set_font): Catch internal error.
4492 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4494 Avoid overflow in w32 implementation of interval timers.
4495 When possible, for ITIMER_PROF count only times the main thread
4497 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4498 'volatile ULONGLONG' types. All the other data which was
4499 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4500 (GetThreadTimes_Proc): New typedef.
4501 (w32_get_timer_time): New function, returns a suitable time value
4503 (timer_loop): Enter critical section when accessing ULONGLONG
4504 values of the itimer_data struct, as these accesses are no longer
4505 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4506 Remove unused variable.
4507 (init_timers): Initialize s_pfn_Get_Thread_Times.
4508 (start_timer_thread): Don't assign itimer->caller_thread here.
4509 (getitimer): Assign itimer->caller_thread here.
4510 (setitimer): Always call getitimer to get the value of ticks_now.
4511 (sys_spawnve): Avoid compiler warning about format mismatch.
4513 2012-10-26 Eli Zaretskii <eliz@gnu.org>
4515 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4516 mouse movement events if the menu bar is active. This avoids
4517 producing a busy "hour-glass" cursor by Windows if the mouse
4518 pointer is positioned over a tooltip shown for some menu item.
4520 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4522 Don't assume process IDs fit in int.
4523 * emacs.c (shut_down_emacs) [!DOS_NT]:
4524 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4525 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4526 Use pid_t, not int, to store process IDs, as 'int'
4527 is not wide enough on a few platforms (e.g., AIX and IRIX).
4529 2012-10-23 Kenichi Handa <handa@gnu.org>
4531 The following change is to make face-font-rescale-alist work
4532 correctly for non-ASCII fonts.
4534 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4535 (font_open_for_lface): Handle Vface_font_rescale_alist.
4537 2012-10-23 Chong Yidong <cyd@gnu.org>
4539 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4541 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
4543 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
4545 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
4547 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
4550 2012-10-21 Glenn Morris <rgm@gnu.org>
4552 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4554 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4556 Port to OpenBSD 5.1.
4557 * frame.c (Fmouse_position, Fmouse_pixel_position):
4558 * xdisp.c (produce_stretch_glyph):
4559 Declare local vars only when they're needed.
4560 This is clearer and avoids a warning on OpenBSD about unused vars.
4561 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
4562 This is safer, and avoids OpenBSD warnings about unused vars.
4563 * keyboard.c (record_menu_key): Remove unnecessary decl.
4564 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4565 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4566 as our definition clashes with OpenBSD's.
4567 * xfaces.c (load_face_colors, check_lface_attrs)
4568 (get_lface_attributes_no_remap, get_lface_attributes)
4569 (lface_fully_specified_p, x_supports_face_attributes_p)
4570 (tty_supports_face_attributes_p, face_fontset, realize_face)
4571 (realize_x_face, realize_tty_face):
4572 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4573 merely Lisp_Object *. This is more informative and avoids
4574 a warning on OpenBSD about accessing beyond an object's size.
4576 2012-10-20 Chong Yidong <cyd@gnu.org>
4578 * lread.c (Fload): Doc fix (Bug#12592).
4580 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
4582 * font.c (Ffont_at): Fix previous change.
4584 2012-10-19 Eli Zaretskii <eliz@gnu.org>
4586 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
4587 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
4590 * alloc.c (NSTATICS): Decrease to 0x800.
4592 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
4594 * fns.c (Fnreverse): Include the problem element when signaling an
4597 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
4599 * nsterm.m (ns_select): Check writefds before call to
4600 FD_ISSET (Bug#12668).
4602 2012-10-18 Daniel Colascione <dancol@dancol.org>
4604 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4605 (staticpro): If we run out of staticpro slots, die with an
4606 informative error instead of just calling emacs_abort.

4865 since unsigned is guaranteed to have that behavior and signed is not.
4866 (read_char): Use ptrdiff_t for string length.
4867 (get_input_pending): Remove first argument, since it was always
4868 the same pointer-to-int (now pointer-to-boolean) &input_pending,
4869 and behave as if it had that value. Return new value of
4870 input_pending. All callers changed.
4871 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4872 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

4875 All callers changed.

4901 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
4903 * commands.h (immediate_quit): Remove duplicate decl.

4915 match what GetLastError returns. Explain why the function is
4918 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4919 'is_tooltip_frame', to avoid confusion with its global namesake.
4921 2012-10-08 Daniel Colascione <dancol@dancol.org>
4923 * xdisp.c (start_hourglass): Call w32_note_current_window when
4924 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4925 build that caused Emacs to display the hourglass cursor forever.
4927 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4928 which is broken under remote desktop, calculate the number of
4929 colors available for a display based on the display's number of
4930 planes and number of bits per pixel per plane. (bug#10397).
4932 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4934 * nsfont.m (Vfonts_in_cache): New variable.
4935 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4936 are used. Add cached fonts to Vfonts_in_cache.
4937 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4939 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4941 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now

4961 ($(BLD)/w32proc.$(O)): Add w32common.h.
4963 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now

4967 2012-10-08 Daniel Colascione <dancol@dancol.org>
4969 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4970 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4971 accidental message numbering hole. Change other messages to

4991 * w32fns.c: Include w32common.h; include w32heap.h only in
4994 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4995 Use `report_file_error' instead of `error' in order to better
4996 inform users of what went wrong. Increase NTGUI_UNICODE file
4997 dialog box file name length to 32k, the maximum allowed by the NT
5000 * w32common.h: New file.
5001 (ROUND_UP, ROUND_DOWN, get_page_size)

5005 (OS_NT, os_subtype, cache_system_info): Move here.
5007 * unexw32.c, unexcw.c: Include w32common.h.
5009 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5010 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5011 to call syms_of_w32select.
5013 * cygw32.h: Remove obsolete EXFUN declarations.
5015 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

5027 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5029 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5032 2012-10-08 Daniel Colascione <dancol@dancol.org>
5034 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5035 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5036 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5037 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5038 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5039 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5040 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5041 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5042 now a supported configuration.
5044 * Makefile.in: consolidate image variables into LIBIMAGE; add
5045 W32_OBJ and W32_LIBS. Compile new files.
5048 (_DebPrint) declare tracing facility for W32 debugging. We need
5049 to unify tracing later.
5051 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5052 unconditional use of W32 Unicode functions. Cygwin runs only on
5053 100% Unicode operating systems.
5055 * cygw32.c: New file. Define Cygwin-specific facilities.
5056 (Fcygwin_convert_path_to_windows)
5057 (Fcygwin_convert_path_from_windows): New user functions for
5058 accessing Cygwin path-munging routines.
5060 * cygw32.h: New file.
5061 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5062 UTF-16LE strings temporarily inside non-Lisp-visible string
5065 (w32_strerror): Just what it says on the tin.
5067 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5068 also run for Cygwin; both systems have the same problem with using
5069 GUI facilities in a forked child. Also call syms_of_cygw32,
5070 syms_of_w32select in correct places.
5072 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5073 needs fork-then-exec for daemon launching.
5075 * font.h: Include frame.h.
5077 * image.c: Use the image library cache machinery only when we're
5078 compiling for native WINDOWSNT; Cygwin can use shared libraries
5079 like any other Unixlike system.
5081 * keyboard.c: Clarify a comment regarding the input loop.
5083 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5084 functions directly instead of trying to detect at runtime that our
5085 host operating system supports them. We make this change for two
5086 reasons: Cygwin lacks support for the multibyte character
5087 conversion functions used by the legacy menu code, and Cygwin
5088 never needs to rely on non-Unicode APIs.
5090 * unexw32.c (hinst): Declare extern.
5092 * w32.c: Change header order;
5093 (w32_strerror): Move to w32fns.c because we need it for
5094 non-WINDOWSNT builds.
5096 * w32.h: Add #error macro to make sure we don't include w32.h for
5097 Cygwin builds. Remove w32select declarations.
5099 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5100 w32fns.c. w32console.c is WINDOWSNT-only.
5102 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5103 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5105 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5106 (w32_major_version, w32_minor_version, w32_build_number)
5107 (os_subtype, sound_type): Define here
5108 (w32_defined_color): Make color parameter const for consistency
5109 with other _defined_color functions.
5110 (w32_createwindow): Unconditionally call w32_init_class instead of
5111 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5112 through the code is complex and unnecessary because class
5113 registration is practically free.
5114 (w32_name_of_message): New EMACSDEBUG-only function.
5115 (Fset_message_beep): Move here
5116 (Fx_open_connection): Require that the display name for Windows be
5117 "w32" for consistency, emacsclient disambiguation, and maybe, one
5118 day, multi-window-system support.
5119 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5120 Cygwin files for W32 GUI facilities, since these clearly don't
5121 expect Cygwin names.
5122 (_DebPrint): Define.
5123 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5124 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5125 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5126 (w32_last_error): Remove.
5128 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5130 * w32heap.c (syspage_mask): Declare here.
5131 (cache_system_info): Remove.
5133 * w32inevt.c (faked_key): Define globally, not statically.
5134 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5135 (w32_console_toggle_lock_key): Move to w32fns.c.
5137 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5139 * w32proc.c (_DebPrint): Move to w32fns.c.
5140 * w32select.c: Include string.h, stdio.h for Cygwin.
5141 * w32select.h: New File.
5143 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5145 (w32_message_fd): New variable. Under Cygwin, holds the file
5146 descriptor the system used to tell us about pending thread
5149 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5150 that prevented compilation under non-WINDOWSNT systems.
5152 (w32_initialize): Open /dev/windows and assign it to
5153 w32_message_fd. Provide w32 feature.
5155 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5156 (WM_EMACS_INPUT_READY): add.
5157 (prepend_msg, w32_message_fd): Declare globally.
5160 (keyboard_handle): Use only when WINDOWSNT.
5161 (notify_msg_ready): New function. Posts a message to the main
5162 thread's message queue under CYGWIN, which wakes up the main
5163 thread from select(2) by making the /dev/windows file descriptor
5164 ready. Under WINDOWSNT, it sets an event the same way the old
5167 (post, prepend_msg): Actually call notify_msg_ready instead of
5168 setting the input event directly.
5170 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5172 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5173 but it still has blocs in it, don't return it to the system,
5174 instead of aborting. (Bug#12402)
5176 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5178 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5180 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5181 MAC_OS_X_VERSION_10_6.
5182 (syms_of_nsterm): Remove comment about Panther and above for
5184 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5185 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5186 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5188 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5189 MAC_OS_X_VERSION_10_4.
5191 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5192 MAC_OS_X_VERSION_10_2.
5194 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5196 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5197 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5199 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5200 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5201 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5202 Remove ns_in_resize check.
5203 (ns_clear_frame_area): Remove resize handle code.
5205 * nsfns.m (ns_in_resize): Remove.
5206 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5207 Remove ns_in_resize check.
5209 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5211 Improve sys_siglist detection.
5212 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5213 defined as a macro, as is done in Solaris.
5214 (sys_siglist_entries): New macro.
5215 (save_strsignal): Use it.
5216 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5217 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5219 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5221 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5222 fullscreen/Fullscreen.
5224 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5225 tobar_height is new.
5227 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5228 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5229 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5230 (windowDidResize:): Check for correct window if old style fullscreen.
5231 Capitalize word in comment. Remove incorrect comment.
5232 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5233 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5234 error in drawing background.
5235 (toggleFullScreen:): Remove comment. Rearrange calls.
5236 Set toolbar values to zero, save old height in tobar_height.
5237 Restore tool bar height when leaving fullscreen.
5238 (canBecomeMainWindow): New function.
5240 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5242 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5244 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5246 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5248 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5249 that time stamps of directories could also be changed.
5250 Don't request the too broad GENERIC_WRITE, only the more restrictive
5251 FILE_WRITE_ATTRIBUTES access rights.
5253 * fileio.c (Fset_file_times): Special-case ignoring errors for
5254 directories only on MSDOS, not on MS-Windows.
5256 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5258 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5260 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5262 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5263 see whether CreateFile failed.
5265 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5267 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5268 to avoid similar races.
5269 * keyboard.c (pending_signals): Now bool, not int.
5271 Port timers to OpenBSD, plus check for timer failures.
5272 OpenBSD problem reported by Han Boetes.
5273 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5275 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5276 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5277 like OpenBSD, which has timer_settime but does not declare it.
5278 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5279 whether to use itimerspec-related primitives. All uses of
5280 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5282 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5284 * profiler.c (handle_profiler_signal): Fix a malloc race
5285 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5287 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5289 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5291 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5293 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5294 consistent with the change in return value of 'safe_strsignal'.
5296 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5298 Prefer plain 'static' to 'static inline' (Bug#12541).
5299 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5300 (bidi_set_sor_type, bidi_push_embedding_level)
5301 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
5302 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

5306 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5307 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5308 Now 'static', not 'static inline'.
5310 Count overruns when profiling; change units to ns.
5311 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5312 Give extra weight to samples after overruns, to attempt to count
5313 the time more accurately.
5314 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5315 the underlying primitives nominally do ns.
5316 (Fprofiler_cpu_start): Document the change. Mention that
5317 the sampling intervals are only approximate.
5319 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5321 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5323 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5324 case for the special 0 coding-system.
5326 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5327 (Fmake_overlay): Remove redundant tests.
5328 (fix_start_end_in_overlays): Remove redundant recentering.
5330 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5332 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5333 Update dependencies.
5335 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5337 Fix a malloc race condition involving strsignal.
5338 A signal can arrive in the middle of a malloc, and Emacs's signal
5339 handler can invoke strsignal, which can invoke malloc, which is
5340 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5341 Fix it by altering the signal handler so that it does not invoke
5343 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5344 * process.c (status_message): Use const pointer, in case strsignal
5345 is #defined to safe_strsignal.
5346 * sysdep.c (sys_siglist, init_signals): Always define and
5347 initialize a substitute sys_siglist if the system does not define
5348 one, even if HAVE_STRSIGNAL.
5349 (safe_strsignal): Rename from strsignal. Always define,
5350 using sys_siglist. Return a const pointer.
5351 * syssignal.h (safe_strsignal): New decl.
5352 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5354 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5356 * w32proc.c (timer_loop): Fix code that waits for timer
5357 expiration, to avoid high CPU usage.
5359 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5361 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5362 (sweep_weak_table): Remove redundant prototypes.
5364 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5366 * emacs.c: Move the inclusion of TERM_HEADER after including
5367 windows.h on WINDOWSNT. This avoids compilation problems with
5370 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5372 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5373 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5374 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5375 as the previous version used 'void *'.
5377 * ralloc.c (ROUNDUP): Fix last change.
5378 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5381 * w32proc.c <disable_itimers>: New static flag.
5382 (init_timers): Initialize it to zero, after creating the critical
5383 sections used by the timer threads.
5384 (term_timers): Set to 1 before deleting the critical sections.
5385 (getitimer, setitimer): If disable_itimers is non-zero, return an
5386 error indication without doing anything. Reported by Fabrice
5387 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5388 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5390 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5393 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5394 term_ntproc after all the other bookkeeping, to get timers working
5395 as long as possible.
5397 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5399 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5400 Suggested by Juri Linkov in
5401 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5403 Prefer plain 'static' to 'static inline' (Bug#12541).
5404 With static functions, modern compilers inline pretty well by
5405 themselves; advice from programmers often hurts as much as it helps.
5406 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5407 this change shrinks the text size of the Emacs executable by 1.1%
5408 without affecting CPU significantly in my benchmark.
5409 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

5484 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
5485 Now 'static', not 'static inline'.
5488 (bidi_copy_it): Do the whole copy with a single memcpy.
5489 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
5491 Revert the FOLLOW-SYMLINKS change for file-attributes.
5492 Doing it right would require several changes to Tramp, and there's
5493 not enough time to get that tested before the freeze today.
5494 * dired.c (directory_files_internal, Ffile_attributes):
5497 * frame.c (x_report_frame_params): Port better to wider ints.
5498 Do not assume that EMACS_UINT is the same width as uprintmax_t,
5499 or that pointers can be printed in 15 decimal digits.
5500 Avoid GCC warnings if EMACS_UINT is wider than a pointer.
5502 2012-09-30 Fabrice Popineau <fabrice.popineau@supelec.fr>

5517 compatibility with x64.
5519 * w32heap.h: Adjust prototypes and declarations.
5521 * w32heap.c (RVA_TO_PTR, allocate_heap, sbrk, init_heap)
5522 (round_heap): Use DWORD_PTR, ptrdiff_t and size_t instead of
5523 DWORD, long, and unsigned long, for compatibility with x64.
5524 (allocate_heap) [_WIN64]: Reserve 32GB of memory.

5702 (handle_profiler_signal): Rename from sigprof_handler_1,
5703 for consistency with other handlers. Do not check whether
5704 cpu_log is a hash-table if garbage collecting, since it

5707 for consistency with other handlers.
5708 (setup_cpu_timer): New function, with much of what used to be in

5710 Prefer timer_settime if available, and prefer
5711 thread cputime clocks, then process cputime clocks, then
5712 monotonic clocks, to the old realtime clock. Use make_timeval
5713 to round more-correctly when falling back to setitimer.
5714 (Fprofiler_cpu_start): Use it.
5715 (Fprofiler_cpu_stop): Prefer timer_settime if available.

5857 (sys_kill): Improve commentary.
5859 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5860 consistency with a signature of a signal handler. All callers

5985 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5987 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5988 fatal_error_backtrace.
5990 * w32proc.c (sys_kill): Undo last change: don't do anything when
5991 invoked to deliver SIGABRT to our own process. This is now
5992 handled by emacs_raise.
5994 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5996 * w32term.c (w32_read_socket): Remove leftover reference to
5997 interrupt_input_pending.
5999 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6001 Do not use SA_NODEFER.
6002 Problem reported by Dani Moncayo in
6003 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6005 * sysdep.c (emacs_abort): Do not reset signal handler.
6006 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6007 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6008 wanted even on POSIXish hosts, and it doesn't work on Windows.
6010 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6012 * xterm.c (x_term_init): Call fixup_locale before and after calling
6013 gtk_init (Bug#12392).
6015 2012-09-23 Chong Yidong <cyd@gnu.org>
6017 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6018 Vdynamic_library_alist.
6020 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6021 (Fgnutls_available_p): Caller changed.
6023 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6024 (Flibxml_parse_xml_region): Likewise.
6026 * dispextern.h (struct image_type): Remove arg from init function.
6028 * image.c (Finit_image_library, lookup_image_type)
6029 (define_image_type): Remove now-unneeded second arg.
6030 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6031 (init_tiff_functions, init_gif_functions, init_svg_functions):
6032 Arglist and w32_delayed_load calling convention changed.
6033 (gs_type): Remove init_gs_functions; there is no such function.
6034 (valid_image_p, make_image): Fix caller to lookup_image_type.
6036 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6038 Simplify and avoid signal-handling races (Bug#12471).
6040 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6041 Avoid recursive loop if there's a fatal error in the function itself.
6042 * atimer.c (pending_atimers):
6043 * blockinput.h: Don't include "atimer.h"; no longer needed.
6044 (interrupt_input_pending): Remove. All uses removed.
6045 pending_signals now counts both atimers and ordinary interrupts.
6046 This is less racy than having three separate pending-signal flags.
6047 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6049 Rename from their upper-case counterparts BLOCK_INPUT,
6050 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6051 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6052 This makes it easier to access volatile variables more accurately.
6053 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6054 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6055 that's more reliable if the code is buggy and sets
6056 interrupt_input_blocked to a negative value. All uses changed.
6057 * atimer.c (deliver_alarm_signal):
6058 Remove. No need to deliver this to the parent; any thread can
6059 handle this signal now. All uses replaced by underlying handler.
6060 * atimer.c (turn_on_atimers):
6061 * dispnew.c (handle_window_change_signal):
6062 * emacs.c (handle_danger_signal):
6063 * keyboard.c (kbd_buffer_get_event):
6064 Don't reestablish signal handler; not needed with sigaction.
6065 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6067 Rework to avoid unnecessary accesses to volatile variables.
6068 (UNBLOCK_INPUT_TO): Now a function.
6069 (totally_unblock_input, unblock_input): New decls.
6070 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6071 (init_data): Remove. Necessary stuff now done in init_signal.
6072 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6073 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6074 (fatal_error_code): Remove; no longer needed.
6075 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6076 it doesn't always backtrace. All uses changed. No need to reset
6077 signal to default, since sigaction and/or die does that for us now.
6078 Use emacs_raise (FOO), not kill (getpid (), FOO).
6079 (main): Check more-accurately whether we're dumping.
6080 Move fatal-error setup to sysdep.c
6081 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6082 * gtkutil.c (xg_get_file_name, xg_get_font):
6083 Remove no-longer-needed signal-mask manipulation.
6084 * keyboard.c, process.c (POLL_FOR_INPUT):
6085 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6086 * keyboard.c (read_avail_input): Remove.
6087 All uses replaced by gobble_input.
6088 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6089 (kbd_buffer_store_event_hold, gobble_input):
6090 (record_asynch_buffer_change) [USABLE_SIGIO]:
6091 (store_user_signal_events):
6092 No need to mess with signal mask.
6093 (gobble_input): If blocking input and there are terminals, simply
6094 set pending_signals to 1 and return. All hooks changed to not
6095 worry about whether input is blocked.
6096 (process_pending_signals): Clear pending_signals before processing
6097 them, in case a signal comes in while we're processing.
6098 By convention callers now test pending_signals before calling us.
6099 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6100 New functions, to support changes to blockinput.h.
6101 (handle_input_available_signal): Now extern.
6102 (reinvoke_input_signal): Remove. All uses replaced by
6104 (quit_count): Now volatile, since a signal handler uses it.
6105 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6106 All callers changed. Block SIGINT only if not already blocked.
6107 Clear sigmask reliably, even if Fsignal returns, which it can.
6108 Omit unnecessary accesses to volatile var.
6109 (quit_throw_to_read_char): No need to restore sigmask.
6110 * keyboard.c (gobble_input, handle_user_signal):
6111 * process.c (wait_reading_process_output):
6112 Call signal-handling code rather than killing ourselves.
6113 * lisp.h: Include <float.h>, for...
6114 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6115 (pending_signals): Now volatile.
6116 (syms_of_data): Now const if IEEE floating point.
6117 (handle_input_available_signal) [USABLE_SIGIO]:
6118 (terminate_due_to_signal, record_child_status_change): New decls.
6119 * process.c (create_process): Avoid disaster if memory is exhausted
6120 while we're processing a vfork, by tightening the critical section
6122 (send_process_frame, process_sent_to, handle_pipe_signal)
6123 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6125 (send_process): No need for setjmp/longjmp any more, since the
6126 SIGPIPE stuff is now gone. Instead, report an error if errno
6128 (record_child_status_change): Now extern. PID and W are now args.
6129 Return void, not bool. All callers changed.
6130 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6131 Remove. All uses removed. This bug should be fixed now in a
6133 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6134 and record the child status change directly. This avoids the
6135 need to futz with the signal mask.
6136 (process_fatal_action): Move here from emacs.c.
6137 (emacs_sigaction_flags): New function, containing
6138 much of what used to be in emacs_sigaction_init.
6139 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6140 caught by emacs, to make races less likely.
6141 (deliver_process_signal): Rename from handle_on_main_thread.
6143 (BACKTRACE_LIMIT_MAX): Now at top level.
6144 (thread_backtrace_buffer, threadback_backtrace_pointers):
6146 (deliver_thread_signal, deliver_fatal_thread_signal):
6147 New functions, for more-accurate delivery of thread-specific signals.
6148 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6149 (deliver_arith_signal): Handle in this thread, not
6150 in the main thread, since it's triggered by this thread.
6151 (maybe_fatal_sig): New function.
6152 (init_signals): New arg DUMPING so that we can be more accurate
6153 about whether we're dumping. Caller changed.
6154 Treat thread-specific signals differently from process-general signals.
6155 Block all signals while handling fatal error; that's safer.
6156 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6158 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6159 Ignore SIGPIPE unless batch.
6160 (emacs_backtrace): Output backtrace for the appropriate thread,
6161 which is not necessarily the main thread.
6162 * syssignal.h: Include <stdbool.h>.
6163 (emacs_raise): New macro.
6164 * xterm.c (x_connection_signal): Remove; no longer needed
6165 now that we use sigaction.
6166 (x_connection_closed): No need to mess with sigmask now.
6167 (x_initialize): No need to reset SIGPIPE handler here, since
6168 init_signals does this for us now.
6170 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6172 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6173 background rect may be larger (Bug#12245).
6175 2012-09-23 Chong Yidong <cyd@gnu.org>
6177 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6179 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6181 * .gdbinit: Just stop at fatal_error_backtrace.
6182 See Stefan Monnier's request in
6183 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6184 Remove no-longer-used query of system type.
6186 2012-09-22 Chong Yidong <cyd@gnu.org>
6188 * search.c (Freplace_match): Doc fix (Bug#12325).
6190 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6192 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6193 (Fline_end_position): Doc fix.
6195 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6197 2012-09-22 Chong Yidong <cyd@gnu.org>
6199 * dispextern.h (struct image_type): Add new slot, storing a type
6200 initialization function.
6202 * image.c (define_image_type): Call the image initializer function
6203 if it is defined. Arguments and return value changed.
6204 (valid_image_p, make_image): Callers changed.
6205 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6206 (gif_type, imagemagick_type, svg_type, gs_type):
6207 Add initialization functions.
6208 (Finit_image_library): Call lookup_image_type.
6209 (CHECK_LIB_AVAILABLE): Macro deleted.
6210 (lookup_image_type): Call define_image_type here, rather than via
6211 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6212 (syms_of_image): Move define_image_type calls for xbm_type and
6213 pbm_type to lookup_image_type.
6215 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6217 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6218 'idle_timers' from here ...
6219 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6220 lists, to avoid infloops when the timer does something stupid,
6221 like reinvoke itself with the same or smaller time-out.
6224 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6226 * window.c (Fsplit_window_internal): Handle only Qt value of
6227 Vwindow_combination_limit separately.
6228 (Qtemp_buffer_resize): New symbol.
6229 (Vwindow_combination_limit): New default value.
6232 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6234 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6235 the new overlay string. (Bug#10159)
6237 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6239 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6240 or that fprintf is async-signal-safe. POSIX doesn't require
6243 2012-09-22 Chong Yidong <cyd@gnu.org>
6245 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6248 2012-09-22 Kenichi Handa <handa@gnu.org>
6250 * composite.c (composition_reseat_it): Handle the case that a
6251 grapheme cluster is not covered by a single font (Bug#12352).
6253 2012-09-21 Chong Yidong <cyd@gnu.org>
6255 * image.c (define_image_type): Avoid adding duplicate types to
6256 image_types (Bug#12463). Suggested by Jörg Walter.
6258 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6260 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6261 (print_load_command_name): Add case LC_DATA_IN_CODE.
6262 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6264 2012-09-21 Glenn Morris <rgm@gnu.org>
6266 * eval.c (Frun_hook_with_args_until_success)
6267 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6269 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6271 * fileio.c (Ffile_selinux_context): Only call freecon when
6272 lgetfilecon succeeded.
6273 (Fset_file_selinux_context): Likewise. (Bug#12444)
6275 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6277 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6278 reordering, locate the cursor by calling set_cursor_from_row; if
6279 that fails, clear the desired glyph matrix before returning a
6280 failure indication to the caller. Fixes leaving garbled display
6281 when fast scrolling with a down-key. (Bug#12403)
6282 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6283 scrolling through multibyte text.
6285 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6287 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6288 calling mark_vectorlike since that's the one that marks the window.
6289 (mark_discard_killed_buffers): Mark the final cdr.
6290 * window.h (struct window): Move prev/next_buffers to the
6291 non-standard fields.
6292 * window.c (make_window): Initialize prev/next_buffers manually.
6294 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6296 Omit unused arg EXPECTED from socket hooks.
6297 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6298 * nsterm.m (ns_term_init):
6299 * termhooks.h (struct terminal.read_socket_hook):
6300 * w32inevt.c (w32_console_read_socket):
6301 * w32term.c (w32_read_socket):
6302 * xterm.c (XTread_socket):
6303 Omit unused arg EXPECTED. All callers changed.
6304 (store_user_signal_events): Return void, not int, since callers no
6305 longer care about the return value. All uses changed.
6307 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6309 * w32gui.h (XParseGeometry): Do not declare.
6311 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6313 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6314 Ignore 'expected'. See Eli Zaretskii in
6315 <http://bugs.gnu.org/12471#8> (last line).
6317 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6318 (XParseGeometry): Now static. Substitute extremal values for
6319 values that are out of range.
6321 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6323 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6325 * nsfns.m (XParseGeometry): Remove.
6326 (Fx_create_frame): Call x_set_offset to correctly interpret
6327 top_pos in geometry.
6329 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6330 (Fx_parse_geometry): If there is a space in string, call
6331 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6333 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6335 * search.c (scan_buffer): Use character positions in calls to
6336 region_cache_forward and region_cache_backward, not byte
6337 positions. (Bug#12196)
6339 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6340 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6342 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6343 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6344 emacs_blocked_malloc, now deleted.
6346 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6348 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6349 The workaround was for improving performance on Solaris 2.4, but
6350 is getting in the way now. Emacs will still work if someone is
6351 still running Solaris 2.4 in a museum somewhere; Sun dropped
6352 support for Solaris 2.4 in 2003.
6353 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6354 * process.c (create_process) [HAVE_WORKING_VFORK]:
6355 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6356 since Emacs no longer uses vfork on that platform.
6358 2012-09-17 Glenn Morris <rgm@gnu.org>
6360 * emacs.c: Use COPYRIGHT.
6362 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6364 Remove configure's --without-sync-input option (Bug#12450).
6365 When auditing signal-handling in preparation for cleaning it up,
6366 I found that SYNC_INPUT has race conditions and would be a real
6367 pain to fix. Since it's an undocumented and deprecated
6368 configure-time option, now seems like a good time to remove it.
6369 Also see <http://bugs.gnu.org/11080#16>.
6370 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6371 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6372 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6373 (malloc_hysteresis):
6374 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6375 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6376 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6377 (dont_register_blocks, bytes_used_when_reconsidered)
6378 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6379 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6380 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6381 Remove. All uses removed.
6382 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6383 implementation, one that depends on whether the new macro
6384 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6386 * atimer.c (run_timers, handle_alarm_signal):
6387 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6388 (handle_async_input, process_pending_signals)
6389 (handle_input_available_signal, init_keyboard):
6390 * nsterm.m (ns_read_socket):
6391 * process.c (wait_reading_process_output):
6392 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6393 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6395 * xterm.c (XTread_socket):
6397 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6398 * eval.c (handling_signal): Remove. All uses removed.
6399 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6400 All uses replaced with the SYNC_INPUT version.
6401 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6403 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6406 * font.c (Ffont_shape_gstring): Remove unused local.
6408 2012-09-16 Glenn Morris <rgm@gnu.org>
6410 * Makefile.in (clean): No longer run nextstep's clean.
6412 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6414 (ns-app): Move here from ns.mk, and simplify.
6415 (clean): Simplify nextstep entry.
6416 * ns.mk: Remove file.
6418 2012-09-17 Kenichi Handa <handa@gnu.org>
6420 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6421 not covert the last few charactes.
6423 2012-09-16 Kenichi Handa <handa@gnu.org>
6425 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6426 here, but just check the validity of glyphs in the glyph-string.
6428 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6430 * window.c (Fwindow_parameter, Fset_window_parameter):
6431 Accept any window as argument (Bug#12452).
6433 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6435 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6436 to ns_term_init to avoid memory leak.
6438 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6439 explicit retain/release.
6440 (ns_term_init): Only allow one display. Initialize outerpool and
6443 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6445 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6446 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6447 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6448 the Microsoft problem in a different way, by altering ../nt/config.nt.
6450 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6465 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6466 by lisp.h. This completes removal of setjmp.h inclusion
6467 erroneously announced in the previous commit. (Bug#12446)
6469 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6472 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6473 not defined as a macro. The latter happens on MS-Windows.
6476 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6478 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6479 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6480 Some instances of '#include <setjmp.h>' removed, if the
6481 only reason for the instance was because "lisp.h" was included.
6482 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6483 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6484 and _longjmp with the new symbols. Emacs already uses _setjmp if
6485 available, so this change affects only POSIXish hosts that have
6486 sigsetjmp but not _setjmp, such as some versions of Solaris and
6487 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6488 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6489 (png_load_body) [HAVE_PNG]:
6490 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6491 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6492 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6493 since PNG requires jmp_buf. This is the only exception to the
6494 general rule that we now use sys_setjmp and sys_longjmp.
6495 This exception is OK since this code does not change the signal
6496 mask or longjmp out of a signal handler.
6498 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6500 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6501 Include "syssignal.h", for 'main_thread'.
6503 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6505 Avoid out-of-range marker position (Bug#12426).
6506 * insdel.c (replace_range, replace_range_2):
6507 Adjust markers before overlays, as suggested by comments.
6508 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6509 Remove redundant check before calling offset_intervals.
6511 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6513 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6514 current buffer (Bug#12387).
6516 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6518 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6520 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6522 Use a more backwards-compatible timer format (Bug#12430).
6523 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6524 vector element, not from the 4th, since PSECS is now at the end.
6525 (Fcurrent_idle_time): Doc fix.
6527 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6529 Function to mark objects and remove killed buffers at once.
6530 * alloc.c (discard_killed_buffers): Rename to ...
6531 (mark_discard_killed buffers) ... new name. Add marking
6532 of remaining objects. Fix comment. Adjust users.
6533 (mark_object): Do not touch frame buffer lists here.
6534 * frame.c (delete_frame): Reset frame buffer lists here.
6536 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6538 Better workaround for GNOME bug when --enable-gcc-warnings.
6539 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6540 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6541 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6543 Simplify SIGIO usage (Bug#12408).
6544 The code that dealt with SIGIO was crufty and confusing, e.g., it
6545 played tricks like "#undef SIGIO" but these tricks were not used
6546 consistently. Simplify mostly by not #undeffing standard symbols,
6547 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6548 or not as we please) rather than "defined SIGIO" (standard symbol
6549 that we probably shouldn't #undef).
6550 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6551 Modules that need it can include it.
6552 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6553 * dispextern.h (ignore_sigio): New decl.
6554 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6555 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6556 * emacs.c (shut_down_emacs):
6557 * keyboard.c (kbd_buffer_store_event_hold):
6558 Use ignore_sigio rather than invoking 'signal' directly.
6559 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6561 (FIONREAD, SIGIO): Do not #undef.
6562 (tty_read_avail_input): Use #error rather than a syntax error.
6563 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6564 for I_PIPE, used by SETUP_SLAVE_PTY.
6565 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6566 * sysdep.c (croak): Remove; no longer needed. This bit of
6567 temporary code, with Fred N. Fish's comment that it's temporary,
6568 has been in Emacs since at least 1992!
6569 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6570 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6571 * syssignal.h (croak): Remove decl.
6572 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6573 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6574 now that we're termios-only.
6575 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6576 * term.c (dissociate_if_controlling_tty): Use #error rather than
6579 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6580 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6581 to work around GNOME bug 683906.
6582 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6583 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6584 This works around GCC bug 54561.
6586 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6588 More fixes for 'volatile' and setjmp/longjmp.
6589 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6590 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6591 (png_load_body) [HAVE_PNG]:
6592 (jpeg_load_body) [HAVE_JPEG]:
6593 New function, with most of the old parent function's body.
6594 (png_load) [HAVE_PNG]:
6595 (jpeg_load) [HAVE_JPEG]:
6596 Invoke the new function, to avoid longjmp munging our locals.
6597 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6598 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6599 longjmp is passed 2, as the C standard doesn't guarantee this.
6600 Instead, store the failure code into mgr->failure_code.
6602 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6604 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6605 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6606 (syms_of_keyboard): Remove support for unread-command-char.
6608 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6610 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6611 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6612 violation. (Bug#12426)
6614 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6616 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6618 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6620 * eval.c: Add `inhibit-debugger'.
6621 (Qinhibit_debugger): New symbol.
6622 (call_debugger): Bind it instead of Qdebug_on_error.
6623 (maybe_call_debugger): Test Vinhibit_debugger.
6624 (syms_of_eval): Define inhibit-debugger.
6625 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6626 (syms_of_xdisp): Remove inhibit-debug-on-message.
6628 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6630 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6631 If a nonvolatile local variable is written before a _longjmp to
6632 the frame containing the variable, and is read after the _longjmp,
6633 the value read is indeterminate. Some local variables of type
6634 'struct handler' and 'struct catchtag' are used in this way, so
6635 mark each of their slots as volatile if the slot can be set before
6636 _longjmp and read afterwards.
6637 * lisp.h (struct handler): var and chosen_clause are now volatile.
6638 (struct catchtag): val, next, and pdlcount are now volatile.
6640 * bidi.c (bidi_push_it, bidi_pop_it):
6641 * fns.c (copy_hash_table):
6642 * image.c (define_image_type):
6643 * keyboard.c (kbd_buffer_store_event_hold):
6644 * process.c (Fprocess_send_eof):
6645 * xfaces.c (x_create_gc) [HAVE_NS]:
6646 * xgselect.c (xg_select):
6647 Prefer assignment to memcpy when either will do.
6649 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6650 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6651 time an item is removed. No need to mark this function 'inline';
6652 the compiler knows better than we do.
6654 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6656 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6657 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6658 to change_frame_size (Bug#12388).
6659 (windowDidResize:): Pass YES to updateFrameSize.
6661 * nsterm.h: Add delay parameter to updateFrameSize.
6663 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6665 Discard killed buffers from deleted window and frame objects.
6666 This reduces an amount of references to killed buffers and
6667 helps GC to reclaim them faster.
6668 * alloc.c (discard_killed_buffers): New function.
6669 (mark_object): Use it for deleted windows and frames.
6670 (mark_object): If symbol's value is set up for a killed buffer
6671 or deleted frame, restore its global binding.
6672 * data.c (swap_in_global_binding): Add GC notice.
6673 (swap_in_symval_forwarding): Use convenient set_blv_where.
6674 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6675 * window.h: ... to here.
6677 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6679 Convenient macro to check whether the buffer is live.
6680 * buffer.h (BUFFER_LIVE_P): New macro.
6681 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6682 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6684 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6686 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6687 composition cases (Bug#12364).
6689 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6690 overhang of succeeding glyphs overlapping box cursor.
6692 * w32term.c (x_draw_glyph_string): Likewise.
6694 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6696 Simplify, document, and port floating-point (Bug#12381).
6697 The porting part of this patch fixes bugs on non-IEEE platforms
6698 with frexp, ldexp, logb.
6699 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6701 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6702 support, by removing commented-out code and briefly listing the
6703 C89 functions excluded. The commented-out stuff was confusing
6704 maintenance, e.g., we thought we needed cbrt but it was commented out.
6705 (logb): Remove decl; no longer needed.
6706 (isfinite): New macro, if not already supplied.
6707 (isnan): Don't replace any existing macro.
6708 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6709 are present on all C89 platforms.
6710 (Ffrexp): Do not special-case zero, as frexp does the right thing
6712 (Flogb): Do not use logb, as it doesn't have the desired meaning
6713 on hosts that use non-base-2 floating point. Instead, stick with
6714 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6715 frexp, to avoid getting an unspecified result.
6717 * xdisp.c (Qinhibit_debug_on_message): Now static.
6719 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6721 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6722 NSBezierPath (Bug#12131).
6724 2012-09-10 Chong Yidong <cyd@gnu.org>
6726 * fns.c (Fdelq, Fdelete): Doc fix.
6728 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6730 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6731 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6733 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6735 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6736 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6739 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6741 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6742 left fringe if the window has a left margin. This avoids leaving
6743 traces of the cursor because its leftmost pixel is not drawn over.
6745 * dispnew.c (update_window_line): When the left margin area of a
6746 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6747 that screen line. (Bug#12277)
6749 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6751 Assume C89 or later for math functions (Bug#12381).
6752 This simplifies the code, and makes it a bit smaller and faster,
6753 and (most important) makes it easier to clean up signal handling
6754 since we can stop worring about floating-point exceptions in
6755 library code. That was a problem before C89, but the problem
6756 went away many years ago on all practical Emacs targets.
6757 * data.c, image.c, lread.c, print.c:
6758 Don't include <math.h>; no longer needed.
6759 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6760 might be autoconfigured, as that never happens.
6762 * doprnt.c (DBL_MAX_10_EXP):
6763 * print.c (DBL_DIG):
6764 Remove. C89 or later always defines these.
6765 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6766 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6767 (arith_error, domain_error, domain_error2):
6768 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6769 no longer needed -- we simply return what C returns. All uses removed.
6770 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6772 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6773 Remove. All uses expanded, as these macros are no longer used
6774 more than once and are now more trouble than they're worth.
6775 (Ftan): Use tan, not sin / cos.
6776 (Flogb): Assume C89 frexp.
6777 (fmod_float): Assume C89 fmod.
6778 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6779 (init_floatfns): Remove. All uses removed.
6781 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6783 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6784 compositeToPoint for OSX < 10.6 (Bug#12390).
6786 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6788 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6789 This produces more-accurate results.
6791 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6793 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6794 changes (Bug#12088).
6796 2012-09-08 Chong Yidong <cyd@gnu.org>
6798 * syntax.c (Fstring_to_syntax): Doc fix.
6800 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6802 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6803 in the internal border.
6804 (x_set_window_size): Remove static variables and their usage.
6805 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6806 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6807 Remove fringe/internal border adjustment (Bug#11052).
6808 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6809 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6810 (ns_fix_rect_ibw): Remove.
6811 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6812 (ns_dumpglyphs_box_or_relief): Ditto.
6813 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6815 (ns_dumpglyphs_image): Ditto.
6816 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6818 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6819 their usage. Add fringe_extended_p and its use as in other terms.
6820 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6821 scroll bar was removed.
6822 (updateFrameSize): New function.
6823 (windowDidResize): Move code to updateFrameSize and call it.
6825 * nsterm.h (EmacsView): Add updateFrameSize.
6827 2012-09-07 Chong Yidong <cyd@gnu.org>
6829 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6831 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6833 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6835 More signal-handler cleanup (Bug#12327).
6836 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6837 Problem introduced when merging patches. Noted by Eli Zaretskii in
6838 <http://bugs.gnu.org/12327#67>.
6839 * floatfns.c: Comment fix.
6840 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6841 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6842 and anyway the declaration is harmless even if SIGDANGER is not defined.
6843 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6844 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6845 source files not surprisingly expected syssignal.h to define, or
6846 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6847 Include <sys/ioctl.h>, for FIONREAD.
6848 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6849 This eliminates a problem whereby other files mysteriously had
6850 to include "syssignal.h" before including "systty.h" if they
6851 wanted to use "#ifdef SIGIO".
6853 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6855 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6857 * w32.c (sigemptyset): Empty the set.
6858 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6860 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6862 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6864 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6865 (mark_object): Likewise for frame objects.
6867 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6869 * syssignal.h (handle_on_main_thread): Always declare,
6870 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6871 This ports to platforms without HAVE_PTHREAD.
6873 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6875 Signal-handler cleanup (Bug#12327).
6876 Emacs's signal handlers were written in the old 4.2BSD style with
6877 sigblock and sigmask and so forth, and this led to some
6878 inefficiencies and confusion. Rewrite these to use
6879 pthread_sigmask etc. without copying signal sets around. Also,
6880 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6881 'signal', and instead use functions that do not attempt to take
6882 over the system name space. This patch causes Emacs's text
6883 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6884 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6885 Do not include <signal.h> or "syssignal.h", as these
6886 modules do not use signals.
6887 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6888 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6889 Do not include <signal.h>, as "syssignal.h" does that for us now.
6890 * atimer.c (sigmask_atimers): New function.
6891 (block_atimers, unblock_atimers): New functions,
6892 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6894 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6895 no longer needed here.
6896 * emacs.c (main): Inspect existing signal handler with sigaction,
6897 so that there's no need to block and unblock SIGHUP.
6898 * sysdep.c (struct save_signal): New member 'action', replacing
6899 old member 'handler'.
6900 (save_signal_handlers, restore_signal_handlers):
6901 Use sigaction instead of 'signal' to save and restore.
6902 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6903 New function. All users of 'signal' modified to use set_sighandler
6904 if they're writeonly, and to use sys_signal if they're read+write.
6905 (emacs_sigaction_init, forwarded_signal): New functions.
6906 (sys_signal): Remove. All uses replaced by calls to sigaction
6907 and emacs_sigaction_init, or by direct calls to 'signal'.
6908 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6909 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6910 all uses replaced by pthread_sigmask etc. calls.
6911 * syssignal.h: Include <signal.h>.
6912 (emacs_sigaction_init, forwarded_signal): New decls.
6913 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6914 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6915 (sigmask, sys_sigmask): Remove; no longer needed.
6916 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6917 (sigblock, sigunblock, sigfree):
6918 (sigsetmask) [!defined sigsetmask]:
6919 Remove. All uses replaced by pthread_sigmask.
6920 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6921 no longer need to be replaced, and its typical old uses
6922 are now done via emacs_sigaction_init and sigaction.
6923 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6924 (sys_sigdel): Remove; unused.
6925 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6927 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6929 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6930 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6932 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6934 Explicitly mark buffer_defaults and buffer_local_symbols.
6935 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6936 mark_local_symbols here.
6937 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6938 since special buffers aren't marked here any more.
6939 (allocate_buffer): Chain new buffer with all_buffers here...
6940 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6942 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6943 (syms_of_buffer): Remove staticpro of the above.
6944 (init_buffer_once): Set names for buffer_defaults and
6945 buffer_local_symbols.
6947 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6949 Use bool for booleans in font-related modules.
6950 * font.c (font_intern_prop, font_style_to_value)
6951 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6952 (generate_otf_features, font_check_otf_features, font_check_otf)
6953 (font_match_p, font_list_entities, font_at):
6954 * fontset.c (fontset_id_valid_p, reorder_font_vector
6955 (fontset_find_font, Fset_fontset_font)
6956 (face_suitable_for_char_p) [0]:
6957 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6958 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6959 (m17n_flt_initialized, ftfont_shape_by_flt):
6960 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6961 * nsfont.m (nsfont_draw):
6962 * w32font.c (w32font_draw):
6963 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6964 Use bool for booleans.
6965 * font.h: Adjust to above API changes.
6966 (struct font, struct font_driver, struct font_driver_list):
6967 Use bool for booleans.
6968 (struct font): Remove useless member encoding_type.
6970 * fontset.c, xftfont.c: Omit unnecessary static decls.
6972 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6974 * alloc.c (mark_object): Revert window marking code
6975 since it's unsafe for the Fset_window_configuration.
6977 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6979 Fix race conditions with signal handlers and errno (Bug#12327).
6980 Be more systematic about preserving errno whenever a signal
6981 handler returns, even if it's not in the main thread. Do this by
6982 renaming signal handlers to distinguish between signal delivery
6983 and signal handling. All uses changed.
6984 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6985 * data.c (deliver_arith_signal): Rename from arith_error.
6986 * dispnew.c (deliver_window_change_signal): Rename from
6987 window_change_signal.
6988 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6989 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6990 * keyboard.c (deliver_input_available_signal): Rename from
6991 input_available_signal.
6992 (deliver_user_signal): Rename from handle_user_signal.
6993 (deliver_interrupt_signal): Rename from interrupt_signal.
6994 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6995 (deliver_child_signal): Rename from sigchld_handler.
6996 * atimer.c (handle_alarm_signal):
6997 * data.c (handle_arith_signal):
6998 * dispnew.c (handle_window_change_signal):
6999 * emacs.c (handle_fatal_signal, handle_danger_signal):
7000 * keyboard.c (handle_input_available_signal):
7001 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7002 * process.c (handle_pipe_signal, handle_child_signal):
7003 New functions, with the actual signal-handling code taken from the
7004 original respective signal handlers, sans the sporadic attempts to
7005 preserve errno, since that's now done by handle_on_main_thread.
7006 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7007 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7008 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7010 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7011 Move initialization of main_thread to sysdep.c's init_signals.
7012 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7013 our usage, and simplifies the mainline code.
7014 (record_child_status_change): New static function, as a helper
7015 for handle_child_signal, and with most of the old child handler's
7017 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7018 (handle_child_signal): Use the above.
7019 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7020 Moved here from emacs.c.
7021 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7022 code moved here from emacs.c's main function.
7023 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7024 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7025 This lets callers save and restore errno properly.
7027 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7029 Remove redundant or unused things here and there.
7030 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7031 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7032 * editfns.c (Fcompare_buffer_substrings): Likewise.
7033 * frame.h (struct terminal, struct font_driver_list):
7034 Remove redundant declarations.
7035 * window.h (Qleft, Qright): Likewise.
7037 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7039 Do not mark objects from deleted buffers, windows and frames.
7040 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7041 (mark_object): Likewise for windows and frames.
7043 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7045 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7046 buffer_defaults and buffer_local_symbols as valid objects.
7047 Return special value to denote them.
7049 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7051 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7052 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7053 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7054 (file_name_absolute_p, Fsubstitute_in_file_name):
7055 (check_executable, check_writable, Ffile_accessible_directory_p)
7056 (Fset_file_selinux_context, Fdefault_file_modes)
7057 (Finsert_file_contents, choose_write_coding_system)
7058 (Fwrite_region, build_annotations, a_write, e_write)
7060 * filelock.c (boot_time_initialized, get_boot_time)
7061 (get_boot_time_1, lock_file_1, within_one_second):
7062 * floatfns.c (in_float):
7063 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7064 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7065 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7066 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7067 * window.c (compare_window_configurations):
7068 Use bool for booleans.
7069 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7070 (Fdefault_file_modes): Now mode_t, not int, for modes.
7071 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7072 (internal_delete_file): Now returns void, not a (boolean) int,
7073 since nobody was looking at the return value.
7074 * lisp.h, window.h: Adjust to above API changes.
7076 * xdisp.c (set_message): Simplify and reindent last change.
7078 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7080 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7082 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7084 * eval.c (call_debugger): Make the function non-static so that we
7085 can call it from set_message.
7087 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7088 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7090 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7092 Give more-useful info on a fatal error (Bug#12328).
7093 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7094 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7095 of doing the work ourselves.
7096 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7097 do most of the work.
7098 (fatal_error_backtrace): New function, taken from the guts
7099 of the old fatal_error_signal, but with a new option to output
7101 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7102 info about the signal than just its number.
7103 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7104 * sysdep.c: Include <execinfo.h>
7105 (emacs_backtrace): New function, taken partly from the previous
7106 code of the 'die' function.
7107 (emacs_abort): Call fatal_error_backtrace rather than abort.
7109 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7111 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7112 eager (load-time) macro-expansion.
7113 * lisp.mk (lisp): Add macroexp.
7115 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7117 Simplify redefinition of 'abort' (Bug#12316).
7118 Do not try to redefine the 'abort' function. Instead, redo
7119 the code so that it calls 'emacs_abort' rather than 'abort'.
7120 This removes the need for the NO_ABORT configure-time macro
7121 and makes it easier to change the abort code to do a backtrace.
7122 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7123 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7124 Remove; sysdep.c's emacs_abort now takes its place.
7125 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7126 'abort' changed to use 'emacs_abort'.
7127 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7128 (abort) [!defined abort]: Rename to ...
7129 (emacs_abort): ... new name.
7130 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7131 the place of the old 'abort' in emacs.c.
7132 * w32.c, w32fns.c (abort): Do not #undef.
7133 * w32.c (emacs_abort): Rename from w32_abort.
7135 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7137 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7138 offsets[j].dv, since the y axis of the screen coordinates points
7139 down, while the y axis of the font definition coordinates points
7140 up. This fixes display of Arabic diacritics such as KASRA and
7141 KASRATAN. (Bug#11860)
7143 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7145 Be more systematic about _setjmp vs setjmp.
7146 * alloc.c (test_setjmp, mark_stack):
7147 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7148 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7149 (png_load, my_error_exit, jpeg_load):
7150 * process.c (send_process_trap, send_process):
7151 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7152 The underscored versions are up to 30x faster on some hosts.
7153 Formerly, the code used setjmp+longjmp sometimes and
7154 _setjmp+_longjmp at other times, with no particular reason to
7155 prefer setjmp+longjmp.
7157 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7159 Fix minor problem found by static checking.
7160 * buffer.c (Fdelete_all_overlays): Return nil.
7162 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7164 * buffer.c (Fdelete_all_overlays): New function.
7166 2012-09-03 Chong Yidong <cyd@gnu.org>
7168 * gtkutil.c: Add extern decl for Qxft.
7170 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
7172 * emacs.c, eval.c: Use bool for boolean.
7173 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
7174 (malloc_using_checking) [DOUG_LEA_MALLOC]:
7175 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
7176 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)

7179 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
7180 (maybe_call_debugger, Fbacktrace):
7181 * process.c (read_process_output, exec_sentinel):
7182 Use bool for booleans.
7183 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
7184 All callers changed.
7185 * eval.c (interactive_p): Omit always-true boolean argument
7186 EXCLUDE_SUBRS_P. All callers changed.
7187 * dispextern.h, lisp.h: Reflect above API changes.
7188 * firstfile.c (dummy): Use the address of 'main', whose signature
7189 won't change, instead of the address of 'initialize', whose
7190 signature just changed from int to bool.
7191 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7192 * msdos.c (fatal_error_in_progress): ... from here.
7193 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7195 (redisplay_internal, unwind_redisplay): Simply clear
7196 REDISPLAYING_P when unwinding, instead of saving its previous,
7197 always-false value and then restoring it.
7199 Clean up some extern decls.
7200 Mostly, this hoists extern decls out of .c files and into .h files.
7201 That way, we're more likely to catch errors if the interfaces change.
7202 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7203 declare xg_mark_data.
7204 * dispextern.h (x_frame_parm_handlers):
7206 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
7207 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
7208 (Qultra_bold, Qoblique, Qitalic):
7209 Move extern decl here from .c file.
7210 * alloc.c (xg_mark_data) [USE_GTK]:
7212 * eval.c (Qlexical_binding):
7213 * fns.c (time) [!HAVE_UNISTD_H]:

7219 * process.c (QCfamily, QCfilter):
7220 * widget.c (free_frame_faces):

7222 * xfont.c (x_clear_errors):
7223 * xterm.c (x_frame_parm_handlers):
7224 Remove now-redundant extern decls.
7225 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7226 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7228 * xfaces.c: Remove unnecessary static decls.
7229 * xterm.c (updating_frame): Remove decl of nonexistent object.
7231 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7232 when building globals.h, as the objects that are not built on
7233 this host are not needed to compile C files on this host.
7235 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
7237 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
7239 * frame.h: Add missing prototype for x_wm_set_size_hint.
7241 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

7265 * keyboard.c (decode_timer):
7266 Use bool for boolean.
7267 * intervals.h, lisp.h, systime.h: Reflect above API changes.
7268 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
7270 2012-09-02 Chong Yidong <cyd@gnu.org>
7272 * keymap.c (push_key_description): Print M-TAB as C-M-i
7275 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
7277 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

7287 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7288 more than one grapheme cluster passed to the shaper: compute the
7289 offset adjustment values separately for each cluster. (Bug#11860)
7291 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7292 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7293 about implicit conversions from integer to pointer.
7295 2012-09-01 Daniel Colascione <dancol@dancol.org>
7297 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

7315 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
7316 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
7317 all of which have been moved to common code.
7319 * xfaces.c: Include TERM_HEADER instead of listing all possible
7320 window-system headers.
7322 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

7343 * keyboard.c: Include TERM_HEADER instead of listing all possible
7344 window-system headers.
7346 * image.c: Include TERM_HEADER instead of listing all possible
7347 window-system headers. Declare Vlibrary_cache when compiling for
7350 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
7351 window system declarations.
7353 * frame.h: Move common functions here: set_frame_menubar,
7354 x_set_window_size, x_sync, x_get_focus_frame,
7355 x_set_mouse_position, x_set_mouse_pixel_position,
7356 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
7357 x_char_width, x_char_height, x_pixel_width, x_pixel_height,
7358 x_set_frame_alpha, x_set_menu_bar_lines, x_set_tool_bar_lines,
7359 x_activate_menubar, x_real_positions, x_bitmap_icon,
7360 x_set_menu_bar_lines, free_frame_menubar, x_free_frame_resources,
7363 * frame.c: Include TERM_HEADER instead of listing all possible
7364 window-system headers.
7366 * font.c: Include TERM_HEADER instead of listing all possible
7367 window-system headers.
7369 * emacs.c: Include TERM_HEADER.
7371 * dispnew.c: Include TERM_HEADER instead of listing all possible
7372 window-system headers.

7376 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
7377 the current window system; include in list of objects to link into
7380 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7382 Remove mark_ttys function and fix tty_display_info initialization.
7383 * lisp.h (mark_ttys): Remove prototype.
7384 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
7385 to mark_ttys because all possible values of 'top_frame' slot are
7386 the frames which are reachable from Vframe_list.
7387 * term.c (mark_ttys): Remove.
7388 (init_tty): Safely initialize 'top_frame' slot with Qnil.
7390 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7392 Change struct frame bitfields from unsigned char to unsigned.
7393 * frame.h (struct frame): Change type of 'display_preempted',

7407 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
7408 does not become zero (Bug#12234).
7410 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
7412 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
7413 for GCC 4.7.1 x86-64.
7415 2012-08-30 Glenn Morris <rgm@gnu.org>
7417 * lread.c (init_lread): For out-of-tree builds, only add the
7418 source directory's site-lisp dir to the load-path if it exists,
7419 consistent with in-tree builds. (Bug#12302)
7421 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
7423 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

7433 (addSplit): Remove return self, declare return value as void.
7434 (clicked:): Remove return self, declare return value as void.
7435 Set dialog_return to button_values[seltag]. Code formatting change.

7437 Code formatting change.
7438 (timeout_handler:): Set timer_fired to YES.
7439 (runDialogAt:): Set timer_fired to NO.
7440 Handle click on close button as quit.
7442 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7443 Add window_closed and button_values. Add void as return value for
7444 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7445 Add process_dialog as new member.
7447 2012-08-28 Eli Zaretskii <eliz@gnu.org>
7449 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
7450 is not one of the heaps we manage. (Bug#12242)
7452 2012-08-28 Glenn Morris <rgm@gnu.org>
7454 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

7511 Use bool for boolean.
7512 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
7513 and remove last int (actually boolean) argument, which was always 0.

7516 * dispextern.h (struct composition_it): Use bool for boolean.
7517 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
7518 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
7519 * dired.c (file_name_completion):
7520 Use bool for boolean. (This was missed in an earlier change.)
7522 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7524 * window.c (Fset_window_configuration): Revert first part of
7527 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>

7585 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
7586 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
7587 not a boolean 'int', since callers never look at the return value.
7588 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.

7590 (emacs_mule_string_char): Remove unused extern decls.
7591 (struct iso_2022_spec, struct coding_system):

7607 buffer doesn't appear in the selected window, go to its old
7610 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7612 Special MEM_TYPE_SPARE to denote reserved memory.
7613 * alloc.c (enum mem_type): New memory type.
7614 (refill_memory_reserve): Use new type for spare memory.
7615 This prevents live_cons_p and live_string_p from incorrect

7644 (map_sub_char_table):
7645 Use bool for boolean.
7646 * character.c (str_to_unibyte): Omit last boolean argument; it was
7647 always 0. All callers changed.
7648 * character.h, charset.h: Adjust to match previous changes.
7649 * character.h (char_printable_p): Remove decl of nonexistent function.
7650 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7651 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7652 are all boolean, so make them single-bit bitfields.
7654 * lisp.h (ASET): Remove attempt to detect side effects.
7655 It was meant to be temporary and it often doesn't work,
7656 because when IDX has side effects the behavior of IDX==IDX
7657 is undefined. See Stefan Monnier in
7658 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7660 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7662 * lisp.h (functionp): New function (extracted from Ffunctionp).
7663 (FUNCTIONP): Use it.
7664 * eval.c (Ffunctionp): Use it.
7666 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7668 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7669 as that's faster and simpler than static storage. Don't bother
7670 with the g_main_context_query overhead if g_main_context_pending
7671 says no events are pending.
7672 (gfds, gfds_size): Remove these static vars.
7673 (xgselect_initialize): Remove; no longer needed.
7674 All uses and decls removed.
7676 * emacs.c (fatal_error_signal_hook): Remove.
7677 All uses removed. This leftover from old code was always 0.
7679 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7680 * casefiddle.c (casify_object, casify_region):
7681 * casetab.c (set_case_table):

7692 On assertion failure, print backtrace if available.
7693 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.

7703 * lisp.h (USE_SAFE_ALLOCA):
7704 Use bool for booleans, instead of int.
7705 * lisp.h, process.h: Adjust prototypes to match above changes.
7706 * callint.c (Fcall_interactively): Don't assume the mark's
7707 offset fits in 'int'.
7709 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7711 * buffer.c, buffer.h: Use bool for boolean.

7719 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7720 Use bool for booleans, instead of int.
7721 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7722 since the 1-or-0 return value is always ignored anyway.
7723 (mmap_initialized_p):
7724 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7725 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7727 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7729 * bidi.c: Use bool for boolean.
7730 This is a bit more readable, and makes the text segment of bidi.o
7731 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7732 Presumably it's faster too.

7739 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7740 Use bool for booleans, instead of int.
7741 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7742 (bidi_unshelve_cache): Adjust decls to match code.
7744 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7746 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7749 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7751 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7752 * atimer.h: Include <stdbool.h>.
7754 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7756 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7757 compile time tests instead of run time tests on systems that do
7759 (FRAME_MAC_P): Remove leftover from deleted code.
7760 * frame.c (syms_of_frame): Remove leftover from deleted code.
7762 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7764 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7766 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7768 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7769 Otherwise, the compiler complains about (A?B:C) where B is void
7770 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7771 (fontset_add): Return void, for FONTSET_ADD.
7773 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7775 * alloc.c: Use bool for booleans.
7776 (gc_in_progress, abort_on_gc)
7777 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7778 (dont_register_blocks) [GC_MALLOC_CHECK]:
7779 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7780 (check_string_bytes, make_specified_string, memory_full)
7781 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7782 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7783 (mark_stack, valid_pointer_p, make_pure_string)
7784 (Fgarbage_collect, survives_gc_p, gc_sweep):
7785 Use bool for booleans, instead of int.
7786 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7787 Remove unused local.
7788 * alloc.c (PURE_POINTER_P):
7789 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7790 * editfns.c (Fformat):
7791 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7793 * fns.c (sweep_weak_table):
7794 * lisp.h (suppress_checking, push_message, survives_gc_p)
7795 (make_pure_string, gc_in_progress, abort_on_gc):
7796 * lread.c (readchar, read1):
7797 * print.c (Fprin1_to_string):
7798 * xdisp.c (push_message):
7799 Use bool for booleans affected directly or indirectly by
7802 Make recently-introduced setters macros.
7803 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7804 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7805 (set_fontset_default, set_fontset_fallback): Rename from their
7806 upper-case counterparts, and make them functions rather than macros.
7807 This is more consistent with the other recently-introduced setters.
7808 These don't need to be inline, since they're local.
7810 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7812 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7813 the loop (Bug#12247).
7815 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7817 * lisp.h (vcopy): Use memcpy rather than our own loop.
7818 This fixes a performance regression introduced by the recent
7819 addition of vcopy. This means 'vcopy' will need to be modified
7820 for a copying collector, but that's OK. Also, tighten the
7821 checking in the assertion.
7823 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7825 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7826 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7827 non-base glyph for the width of the base character, according to
7828 what x_draw_composite_glyph_string_foreground expects.
7829 Generate WADJUST value according to composition_gstring_width's
7830 expectations, to produce correct width of the composed character.
7831 Reverse the sign of the DU offset produced by ScriptPlace.
7833 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7835 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7837 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7839 Avoid direct writes to contents member of struct Lisp_Vector.
7840 * lisp.h (vcopy): New function to copy data into vector.
7841 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7842 * fns.c (Ffillarray): Use ASET.
7843 * keyboard.c (timer_check_2): Use AREF and ASET.
7844 (append_tool_bar_item, Frecent_keys): Use vcopy.
7845 * lread.c (read_vector): Use ASET.
7846 * msdos.c (Frecent_doskeys): Use vcopy.
7847 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7848 (Finternal_merge_in_global_face): Use ASET and vcopy.
7849 * xfont.c (xfont_list_pattern): Likewise.

7853 * window.c (Fwindow_point): For the selected window always return
7854 the position of its buffer's point.
7855 (Fset_window_point): For the selected window always go in its
7856 buffer to the specified position.
7858 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7860 Setter macros for fontsets.
7861 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7862 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7863 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7866 2012-08-20 Glenn Morris <rgm@gnu.org>
7868 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7869 Don't assume that `ln -f' works.
7871 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7873 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7874 and later about non-assignments with no effect. See discussion at
7875 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7878 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7880 Inline setter functions for Lisp_Objects slots of struct specbinding.
7881 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7884 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7886 * window.c (select_window): Always make selected window's buffer
7889 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7891 Use AREF and ASET for docstrings of category tables.
7892 * category.h (CATEGORY_DOCSTRING): Use AREF.
7893 (SET_CATEGORY_DOCSTRING): Use ASET.
7894 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7896 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7898 Inline setter functions for hash table members.
7899 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7900 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7901 (set_hash_key_and_value, set_hash_index, set_hash_next)
7902 (set_hash_hash): New functions.
7903 * charset.c, fns.c: Adjust users.
7905 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7907 Inline getter and setter functions for per-buffer values.
7908 * buffer.h (per_buffer_default, set_per_buffer_default)
7909 (per_buffer_value, set_per_buffer_value): New functions.
7910 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7911 * buffer.c, data.c: Adjust users.
7913 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7915 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7917 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7919 Rely on <config.h> + <unistd.h> to declare 'environ',
7920 as gnulib does this if the system doesn't.
7921 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7922 Remove declaration. MS-Windows declares it on stdlib.h which is
7923 included by conf_post.h.
7924 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7925 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7926 * vm-limit.c: Include <unistd.h>, for 'environ'.
7928 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7929 (start_of_data): Remove decl; mem-limits.h provides it.
7931 * xdisp.c (handle_invisible_prop): Make it a bit faster
7932 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7934 2012-08-19 Chong Yidong <cyd@gnu.org>
7936 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7939 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7941 * .gdbinit: Use call instead of set when calling a function in the
7944 * data.c (set_internal): Don't use set_blv_found.
7945 (Fkill_local_variable): Likewise.
7947 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7949 * nsfont.m (ns_ascii_average_width): Ensure the string
7950 ascii_printable is initialized with a null-terminated character
7951 array. Otherwise, it can contain undesired extra characters.
7953 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7955 port new setting code to Sun C 5.8 2005/10/13
7956 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7957 Return void, not Lisp_Object. Otherwise, the compiler
7958 complains about (A?B:C) where B is void and C is Lisp_Object
7959 when compiling CHAR_TABLE_SET, due to the recent change to
7960 the API of sub_char_table_set_contents.
7962 2012-08-18 Chong Yidong <cyd@gnu.org>
7964 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7965 for the string case (Bug#3874).
7967 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7969 * buffer.h (BSET): Remove (Bug#12215).

8120 The old version was confusing because it used the same name
8121 'parent' for two different things.
8123 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
8125 Functions to get and set Lisp_Object fields of buffer-local variables.

8134 font spec, make the font's attributes take precedence over
8135 directly-specified attributes.
8136 (merge_face_ref): Recognize :font.
8138 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

8792 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
8793 * w32.c (init_environment): Change the default values of many
8794 environment variables in dflt_envvars[] to NULL, to avoid pushing
8795 them into environment when they were not already defined.
8796 Remove the code that deletes site-lisp subdirectories from the default
8797 value of EMACSLOADPATH, as it is no longer needed.
8798 (check_windows_init_file): Now external, not static.
8799 Use Vload_path as is, without adding anything, as this function is now
8800 called when Vload_path is already set up.
8802 * w32.h (check_windows_init_file): Add prototype.
8804 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

8811 installation tree, as appropriate.
8813 * callproc.c (init_callproc_1): Call decode_env_path instead of
8814 doing its equivalent by hand.

8816 the code that sets Vexec_path run on MS-Windows.
8818 * lread.c (init_lread): Add comments to #ifdef's.
8820 * msdos.c (dos_set_window_size, IT_update_begin)

8847 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
8848 Remove unnecessary pointer casts.
8849 * alloc.c (record_xmalloc): New function.
8850 * lisp.h (record_xmalloc): New decl.
8851 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8852 more like a function. This is because the pointer cast is not
8853 needed. All uses changed.
8854 * print.c (print_string, print_error_message): Avoid length recalc.
8856 Improve fix for macroexp crash with debugging (Bug#12118).
8857 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8858 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8859 not supposed to be invoked from the garbage collector.

8861 (gc_aset): New function, which is like ASET but can be
8862 used in the garbage collector.

8891 with addition of handling of symlinks and support for 'lstat'.
8892 If possible, get file's attributes and security information by
8893 handle, not by name. Produce S_IFLNK bit for symlinks, when
8894 called from 'lstat'.
8895 (stat, lstat): New functions, call 'stat_worker'.
8896 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8897 symlinks when the underlying filesystem supports them.
8899 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8901 Fix macroexp crash on Windows with debugging (Bug#12118).
8902 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8903 checking subscripts; problem introduced with the recent
8904 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8905 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8906 since it's used in non-static inline functions now.
8908 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8909 Don't assume buffer size fits in 'int'. Remove unused local.

8927 * character.c (CHARACTER_INLINE):
8928 * charset.c (CHARSET_INLINE):
8929 * composite.c (COMPOSITE_INLINE):
8930 * dispnew.c (DISPEXTERN_INLINE):
8931 * sysdep.c (SYSTIME_INLINE):
8932 Define to EXTERN_INLINE, so that the corresponding functions
8933 are compiled into code.
8934 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
8935 (INLINE_HEADER_END): New macros.
8936 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

8956 hard-coding the path separator.
8958 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
8960 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
8961 This how ASET and AREF are supposed to work, and makes
8962 it easier to think about future improvements. See
8963 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
8964 * charset.h (set_charset_attr): New function.

9345 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
9346 (w32_kbd_patch_key, key_event): Use the codepage returned by
9347 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

9405 * alloc.c (gdb_make_enums_visible): New constant. This ports to

9454 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9455 emacs.c, as this is a more-suitable home. Had this been done earlier
9456 the fix for 12036 would have avoided some of the problems noted in
9457 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9458 would have been more obvious.
9459 * emacs.c: Do not include <verify.h>; no longer needed.

9468 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9469 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9470 not be usable in #if. This simplifies things.
9472 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9474 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

9479 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9480 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9481 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9482 Adjust to changes in lisp.h and emacs.c, by using

9485 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

9487 instead of gdb_valbits.
9488 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9489 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9490 instead of gdb_array_mark_flag.
9491 (xboolvector): Get size from $->size, not $->header.size.

10395 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10396 * nsterm.m (ns_term_init):
10397 Avoid the need for strncpy, by using build_string or
10398 make_unibyte_string directly. Use dtoastr, not snprintf.
10399 * process.c (Fmake_network_process): Diagnose service names that
10400 are too long, rather than silently truncating them or creating
10401 non-null-terminated names.
10402 (Fnetwork_interface_info): Likewise, for interface names.
10403 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10404 Prefer sprintf to strncat.

10417 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10418 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
10419 where argument type is known to be a Lisp_Cons.
10421 2012-07-10 Tom Tromey <tromey@redhat.com>
10423 * bytecode.c (BYTE_CODE_THREADED): New macro.

10433 (build_pure_c_string): New function, defined as static inline. This
10434 provides a better opportunity to optimize away calls to strlen when
10435 the function is called with compile-time constant argument.
10436 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10437 argument, adjust users accordingly. Use build_pure_c_string where
10439 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
10440 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10441 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
10443 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10445 Avoid calls to strlen in miscellaneous functions.
10446 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
10447 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
10448 * lread.c (openp): Likewise.
10450 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10452 Avoid calls to strlen in path processing functions.
10453 * fileio.c (file_name_as_directory): Add comment. Change to add
10454 srclen argument and return the length of result. Adjust users
10456 (directory_file_name): Fix comment. Change to add srclen argument,
10457 swap 1st and 2nd arguments to obey the common convention.
10458 Adjust users accordingly.
10459 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
10461 2012-07-10 Glenn Morris <rgm@gnu.org>

10464 Move PENDING_OUTPUT_COUNT definition to configure.
10466 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
10467 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
10468 * s/gnu.h (DATA_START): Move definitions to configure.
10470 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10471 We include usg5-4-common.h, which defines them both.
10473 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10474 O_RDONLY already includes it).
10476 Stop ns builds setting the EMACSLOADPATH environment variable.
10477 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10478 Now it does not set EMACSLOADPATH, just returns the load-path string.
10479 * nsterm.h: Update accordingly.
10480 * lread.c [HAVE_NS]: Include nsterm.h.
10481 (init_lread) [HAVE_NS]: Use ns_load_path.
10482 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10484 2012-07-09 Glenn Morris <rgm@gnu.org>
10486 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10487 since the included bsd-common.h does so.
10489 Stop ns builds setting the EMACSPATH environment variable.
10490 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10491 (ns_init_paths): Do not set EMACSPATH.
10492 * nsterm.h (ns_exec_path): Add it.
10493 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10496 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10498 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10500 * process.c (wait_reading_process_output): 'waitchannels' was unset
10501 when read_kbd || !NILP (wait_for_cell); fix this.
10503 Add GCC-style 'const' attribute to functions that can use it.
10504 * character.h (char_resolve_modifier_mask):
10505 * keyboard.h (make_ctrl_char):
10506 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10507 (init_character_once, next_almost_prime, init_fns, init_image)
10508 (flush_pending_output, init_sound):
10509 * mem-limits.h (start_of_data):

10517 Minor improvements to make_formatted_string.
10518 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10519 where int is good enough, as vsprintf returns an int.
10520 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10522 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10524 Use make_formatted_string to avoid double length calculation.
10525 * lisp.h (make_formatted_string): New prototype.
10526 * alloc.c (make_formatted_string): New function.
10527 * buffer.c (Fgenerate_new_buffer_name): Use it.

10547 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10549 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10551 Move marker debugging code under MARKER_DEBUG.
10552 * marker.c (MARKER_DEBUG): Move marker debugging code under
10553 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10554 for bootstrap with --enable-checking (~3x slowdown reported
10555 by Juanma Barranquero <lekktu@gmail.com>).
10556 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10558 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10560 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10561 See <http://bugs.gnu.org/11825#29>.
10563 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10565 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10566 has no font, use the frame's font. (Bug#11813)
10567 (display_line): Add commentary about displaying truncation glyphs
10569 (produce_special_glyphs): Move here from term.c.
10571 * term.c (produce_special_glyphs): Move to xdisp.c.
10573 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10576 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10578 * xdisp.c (display_line): Avoid warning about implicit declaration
10581 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10583 * lisp.h: Remove empty conditional.
10585 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10587 * lread.c (load_path_check): Now static.
10589 Fix some minor --with-ns problems found by static checking.
10590 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10591 (x_set_font) [!HAVE_X_WINDOWS]:
10592 * image.c (xpm_load_image) [HAVE_NS]:
10593 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10594 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10595 Remove unused local.
10596 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10597 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10598 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10599 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10600 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10601 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10602 Fix pointer signedness problem.
10603 * xfaces.c (FRAME_X_FONT_TABLE):
10604 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10606 2012-07-07 Glenn Morris <rgm@gnu.org>
10608 * lread.c (load_path_check): New function, split from init_lread.
10609 (init_lread): Reorganize. Motivation:
10610 If EMACSLOADPATH is set, check/warn about that rather than the
10611 defaults, which we are not going to use. Hence we can remove
10612 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10613 Don't warn if site-lisp directories are missing.
10614 If not installed, start from a blank load-path, since
10615 PATH_LOADSEARCH refers to the eventual installation directories.
10617 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10619 Support truncation and continuation glyphs on GUI frames, when
10620 fringes are disabled. (Bug#11832)
10621 * xdisp.c (init_iterator): Get dimensions of truncation and
10622 continuation glyphs even if on GUI frames.
10623 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10624 or both, are absent.
10625 (start_display, move_it_in_display_line_to): Handle the case of a
10626 GUI frame without a fringe to display continuation or truncation
10628 (insert_left_trunc_glyphs): Support GUI frames: make sure
10629 truncation glyphs overwrite enough glyphs from the current line to
10630 have sufficient space in pixels.
10631 (display_line): Support truncation and continuation glyphs on GUI
10632 frames. If some spare pixels are left on the line after inserting
10633 the truncation glyphs, fill that space with a stretch glyph of a
10634 suitably computed width.
10636 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10637 produce_glyphs, to support GUI sessions.
10639 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10641 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10643 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10645 Do not require float-time's arg to fit in time_t (Bug#11825).
10646 This works better on hosts where time_t is unsigned, and where
10647 float-time is applied to the (negative) difference between two times.
10648 * editfns.c (decode_time_components): Last arg is now double *,
10649 not int *, and means to store all the result as a double, without
10650 worrying about whether the seconds part fits in time_t.
10651 All callers changed.
10652 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10653 All callers changed.
10654 (Ffloat_time): Do not fail merely because the specified time falls
10655 outside of time_t range.
10657 2012-07-07 Glenn Morris <rgm@gnu.org>
10659 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10660 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10661 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10663 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10665 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10666 Update dependencies.
10668 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10670 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10672 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

10674 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10675 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10676 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10677 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10679 * xfont.c (compare_font_names): Redo to omit the need for casts.
10681 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10683 * xfns.c (Fx_change_window_property): Doc fix.
10684 * w32fns.c (Fx_change_window_property): Doc fix.
10686 * w32fns.c (Fx_window_property): Accept the same arguments as the
10687 X Windows version. Doc fix.
10688 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10690 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10691 Eli Zaretskii <eliz@gnu.org>
10693 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10694 Windows-specific code from nt/config.nt moved here.
10695 Obsolete settings removed.
10697 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10699 * process.c: Avoid unnecessary calls to gettime.
10700 (wait_reading_process_output): Don't get the time of day
10701 when gobbling data immediately and not waiting, as there's no need
10702 for it in that case. This removes a FIXME.
10704 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10706 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10707 is defined (Bug#11768).
10709 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10711 Fix marker debugging code.
10712 * marker.c (byte_char_debug_check): Do not perform the check
10713 if buffer is not multibyte.
10714 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10715 Call byte_char_debug_check with correct arguments.
10717 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10719 Compile marker debugging code only if ENABLE_CHECKING is defined.
10720 * marker.c (byte_char_debug_check, count_markers):
10721 Use only if ENABLE_CHECKING is defined.
10722 (byte_debug_flag): Remove.
10723 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10724 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10726 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10728 Avoid code repetition in marker-related functions.
10729 * marker.c (attach_marker): New function.
10730 (Fset_marker, set_marker_restricted, set_marker_both)
10731 (set_marker_restricted_both): Use it.
10732 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
10733 Consistently rename charno to charpos.
10734 (marker_position): Add eassert.
10735 (marker_byte_position): Convert to eassert.
10737 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10739 Simplify list operations in unchain_overlay and unchain_marker.
10740 * buffer.c (unchain_overlay): Simplify. Add comment.
10741 * marker.c (unchain_marker): Simplify. Fix comments.

10748 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
10749 * composite.c (autocmp_chars): Likewise.
10750 * editfns.c (buildmark): Remove.
10751 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10752 (save_restriction_save): Use build_marker.
10753 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10754 * window.c (save_window_save): Likewise.
10756 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10758 Do not use Fdelete_overlay in delete_all_overlays
10759 to avoid redundant calls to unchain_overlay.
10760 * buffer.c (drop_overlay): New function.
10761 (delete_all_overlays, Fdelete_overlay): Use it.
10762 * minibuf.c (get_minibuffer): Fix comment.
10764 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10766 Port to OpenBSD 5.1 amd64.
10767 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10768 This is needed for OpenBSD, and should be harmless on all BSD systems.
10769 Also, include <sys/sysctl.h>, as it should be available on all
10770 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10771 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10772 use p_pid member, not kp_proc.pid.
10774 2012-07-06 Glenn Morris <rgm@gnu.org>
10776 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10778 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10780 More xmalloc and related cleanup.
10781 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
10782 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

10785 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
10786 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
10787 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
10788 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
10789 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10791 Omit needless casts involving void * pointers and allocation.
10792 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10793 as the former is more robust if P's type is changed.
10794 Prefer xzalloc to xmalloc + memset 0.
10795 Simplify malloc-or-realloc to realloc.
10796 Don't worry about xmalloc returning a null pointer.
10797 Prefer xstrdup to xmalloc + strcpy.
10798 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10800 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10801 alloca of a constant.

10805 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10806 hscroll is larger than the line width. Fixes long and futile
10807 looping inside extend_face_to_end_of_line (on a TTY) producing
10808 glyphs that are not needed and thrown away.
10810 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10812 * marker.c (set_marker_restricted_both): Simplify by using

10821 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
10822 not defined (Bug#11768).
10823 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
10824 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)

10832 (xg_tool_item_stale_p): Call is_box_type.
10833 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10834 with default display (Bug#11768).
10836 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10838 * xdisp.c (window_hscroll_limited): New function.
10839 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10840 coordinates when window's hscroll is set to insanely large
10841 values. (Bug#11857)
10843 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10906 * fileio.c (time_error_value): Check the right error number.
10907 Problem reported by Troels Nielsen in
10908 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10910 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10912 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10913 This should be fixed in a better way; see Eli Zaretskii in
10914 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10915 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10917 * fileio.c (time_error_value): Rename from special_mtime.
10918 The old name's problems were noted by Eli Zaretskii in
10919 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10921 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10922 This variable's comment says Emacs needs at least one GDB-visible
10923 symbol of type enum pvec_type, to work around GDB problems.
10924 The symbol's value doesn't matter.
10926 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10927 that causes compilation to fail on pre-C99 compilers.
10929 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10931 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
10932 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
10934 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10936 * buffer.c (init_buffer_once): Fix initialization of
10937 headers for buffer_defaults and buffer_local_symbols.
10938 Reported by Juanma Barranquero <lekktu@gmail.com>.
10940 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
10942 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
10943 * lisp.h (enum pvec_type): Use fewer bits.
10944 (PSEUDOVECTOR_SIZE_BITS): New constant.
10945 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
10946 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
10947 change in pvec_type.
10948 (PSEUDOVECTOR_TYPEP): New macro.
10949 (TYPED_PSEUDOVECTORP): Use it.
10950 * fns.c (internal_equal): Adapt code to extract pvectype.
10951 * emacs.c (gdb_pvec_type): Update type.
10952 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
10953 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
10954 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
10955 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10956 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10957 abusing vector->header.next.nbytes.
10958 (live_vector_p): Use PVEC_TYPE.
10959 (mark_object): Adapt code to extract pvectype. Use switch.
10961 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10963 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
10964 Tighten new eassert a bit.
10966 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10968 Fix compilation with --enable-gcc-warnings and -O1
10969 optimization level.
10970 * doprnt.c (doprnt): Change type of tem to int, initialize
10971 to avoid compiler warning. Add eassert.
10972 * search.c (simple_search): Initialize match_byte to avoid
10973 compiler warning. Add eassert.
10975 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10977 Avoid weird behavior with large horizontal scrolls.
10978 Without this change, for example, large hscroll values would
10979 mess up Emacs's display on Fedora 15 x86, presumably due to
10980 overflows in int calculations in the display code.
10981 Also, if buffers had long lines, Emacs would freeze.
10982 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10983 (set_window_hscroll): New function, containing the old guts of
10984 Fset_window_hscroll. Return the clipped value.
10985 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10986 This avoids the need to check against PTRDIFF_MAX.
10988 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10990 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
10992 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
10994 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10996 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10997 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10998 since GCC 4.4.6 issues a bogus warning for them.
11000 Fix bugs in file timestamp newness comparisons.
11001 * fileio.c (Ffile_newer_than_file_p):
11002 * lread.c (Fload): Use full timestamp resolution of files,
11003 not just the 1-second resolution, so that files that are only
11004 slightly newer still count as newer.
11005 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11006 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11008 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11010 * fileio.c: Improve handling of file time marker. (Bug#11852)
11011 (special_mtime): New function.
11012 (Finsert_file_contents, Fverify_visited_file_modtime):
11013 Use it to set special mtime values consistently.
11015 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11017 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11018 marker for non-existing file. (Bug#11852)
11020 2012-07-03 Glenn Morris <rgm@gnu.org>
11022 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11023 and did not make it into globals.h).
11025 2012-07-03 Tom Tromey <tromey@redhat.com>
11027 * window.c (Fset_window_margins, Fset_window_fringes)
11028 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
11029 * textprop.c (Fprevious_property_change): No longer static.
11030 * syntax.c (Fsyntax_table_p): No longer static.
11031 * process.c (Fget_process, Fprocess_datagram_address): No longer

11054 * font.h: Remove EXFUNs.
11055 * dosfns.c (system_process_attributes): Remove EXFUN.
11056 * keymap.h: Remove EXFUNs.
11057 * lisp.h: Remove EXFUNs.
11058 * w32term.h: Remove EXFUNs.
11059 * window.h: Remove EXFUNs.
11060 * xsettings.h: Remove EXFUN.
11061 * xterm.h: Remove EXFUN.
11063 2012-07-03 Glenn Morris <rgm@gnu.org>
11065 * lisp.h (Frandom): Make it visible to C.
11066 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11067 buffer for invisible buffers. (Bug#1229)
11069 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11071 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11072 values which aren't power of 2.
11073 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11074 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11077 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11079 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11081 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11083 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11085 * alloc.c (allocate_vector_block): Remove redundant
11086 calls to mallopt if DOUG_LEA_MALLOC is defined.
11087 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11088 avoid calls to mallopt if zero_vector is returned.
11090 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11092 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11093 is enabled, avoid dereferencing NULL current_sblock if
11096 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11098 Cleanup basic buffer management.
11099 * buffer.h (struct buffer): Change layout to use generic vector
11100 marking code. Fix some comments. Change type of 'clip_changed'
11101 to bitfield. Remove unused #ifndef old.
11102 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11103 (GET_OVERLAYS_AT): Fix indentation.
11104 (for_each_per_buffer_object_at): New macro.
11105 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

11109 struct buffer. Fix comment.
11110 (mark_overlay): New function.

11113 (mark_object): Use it. Adjust marking of misc objects
11114 and related comments.
11116 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11118 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11119 wrapper that is not needed because the wrapped code is a no-op (zero
11120 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11121 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11123 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11125 * alloc.c (mark_buffer): Simplify. Remove prototype.
11126 (mark_object): Add comment. Reorganize marking of vector-like
11127 objects. Use CHECK_LIVE for all vector-like objects except buffers
11128 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11129 Avoid redundant calls to mark_vectorlike for bool vectors.
11131 2012-06-30 Glenn Morris <rgm@gnu.org>
11133 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11135 * epaths.in (PATH_SITELOADSEARCH): New.
11136 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11137 This is rather than relying on --enable-locallisppath elements
11138 having "site-lisp" in their names. (Bug#10208#25, 11658)
11140 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11142 * w32proc.c (sys_select): Accept and ignore one more argument.
11144 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11146 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11147 (pselect) [!MS_DOS]: Redirect to sys_select.
11149 * sysdep.c: Don't include dos.h and dosfns.h.
11151 * process.c (sys_select):
11152 * msdos.c (sys_select): Accept one more argument and ignore it.
11154 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11155 adapt data types and code to that.
11158 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11159 which clashes with the gnulib function of the same name.
11161 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11163 * font.c (font_style_to_value, font_style_symbolic)
11164 (font_prop_validate_style): Add type checks for values in
11167 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11169 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11172 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11174 * xdisp.c (try_window_id): Undo last change.
11176 * w32.c (getwd): Adjust commentary about startup_dir.
11177 (init_environment): Always call sys_access, even in non-MSVC
11178 builds. Don't chdir to the directory of the Emacs executable.
11179 This undoes code from 1997 which was justified by the need to
11180 "avoid conflicts when removing and renaming directories". But its
11181 downside was that every relative file name was being interpreted
11182 relative to the directory of the Emacs executable, which can never
11183 be TRT. In particular, it broke sys_access when called with
11184 relative file names.
11185 (sys_access): Map GetLastError to errno.
11187 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

11193 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11196 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11198 * gnutls.c (emacs_gnutls_handshake):
11199 Add QUIT to make the loop interruptible.
11201 2012-06-29 Glenn Morris <rgm@gnu.org>
11203 * charset.c (init_charset): Make lack of etc/charsets fatal.
11205 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11207 * editfns.c (region_limit): Fix type mismatch.
11209 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11211 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11212 undefined. Convert from xassert to eassert.
11213 * nsmenu.m: Convert from xassert to eassert.
11214 * nsterm.m: Likewise.
11216 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
11218 * editfns.c (region_limit): Clip to narrowing (bug#11770).
11220 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11222 Avoid integer overflow on scroll-left and scroll-right.
11223 * window.c (HSCROLL_MAX): New macro.
11224 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11225 overflow when requested scroll falls outside ptrdiff_t range.
11227 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11229 * window.h (struct window): Change type of 'hscroll',
11230 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11231 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11232 Adjust users accordingly.
11233 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11234 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11235 from EMACS_INT to ptrdiff_t.
11236 (make_window): Omit redundant initialization.
11238 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
11240 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
11242 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11244 * window.h (struct window): Change type of 'use_time' and
11245 'sequence_number' from Lisp_Object to int.
11246 * frame.c (make_frame): Adjust users accordingly.
11247 * print.c (print_object): Likewise.
11248 * window.c (select_window, Fwindow_use_time, make_parent_window)

11251 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11253 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
11254 enabled with --enable-checking=[all,glyphs] configure option.
11255 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11256 adjust comments accordingly.
11257 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
11258 undefined, adjust comments accordingly.

11377 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11379 Use sprintf return value instead of invoking strlen on result.
11380 In the old days this wasn't portable, since some sprintf
11381 implementations returned char *. But they died out years ago and
11382 Emacs already assumes sprintf returns int.
11383 Similarly for float_to_string.
11384 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

11391 * xfns.c (syms_of_xfns):
11392 Use sprintf or float_to_string result to avoid need to call strlen.
11393 * data.c (Fnumber_to_string):
11394 Use make_unibyte_string, since the string must be ASCII.
11395 * lisp.h, print.c (float_to_string): Now returns int length.
11396 * term.c (produce_glyphless_glyph):
11397 Use sprintf result rather than recomputing it.
11399 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

11426 sprintf already null-terminates its output.
11428 * xfns.c (x_window): Remove redundant cast.
11430 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11432 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11433 `const char *' to `char *' to avoid compiler warning.
11435 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11437 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11438 instead of truncating it to 63 (admittedly a generous limit).
11440 * process.c: Fix spelling and caps in comments.

11493 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11495 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
11496 * lisp.h (WAIT_READING_MAX): New macro.
11497 * dispnew.c (Fsleep_for, sit_for):
11498 * keyboard.c (kbd_buffer_get_event):
11499 * process.c (Faccept_process_output):
11500 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11501 This improves on the previous patch, which introduced a bug
11502 when time_t is unsigned and as wide as intmax_t.
11503 See <http://bugs.gnu.org/9000#51>.
11505 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11531 last argument of make_unibyte_string.
11533 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
11534 language ID in the event parameters.
11536 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11537 event.code, not the obscure "character set ID".
11539 2012-06-23 Chong Yidong <cyd@gnu.org>
11541 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

11568 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
11570 Support higher-resolution time stamps (Bug#9000).
11571 The time stamps are only nanosecond-resolution at the C level,
11572 since that's the best that any real-world system supports now.
11573 But they are picosecond-resolution at the Lisp level, as that's
11574 easy, and leaves room for future OS improvements.
11576 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11579 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11580 Don't get current time unless it's needed.
11582 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11583 now provides it if it's absent.
11584 (start_atimer): Port to higher-res time stamps.
11585 Check for time stamp overflow. Don't get current time more
11586 often than is needed.
11588 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11589 Include systime.h, not time.h.
11590 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11592 * dired.c: Include stat-time.h.
11593 (Ffile-attributes): File times now have higher resolution.
11595 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11596 (struct image): Timestamp now has higher resolution.
11598 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11599 has at least microseconds now. All uses removed.
11600 (update_frame, update_single_window, update_window, update_frame_1)
11601 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11602 (duration_to_sec_usec): Remove; no longer needed.
11604 * editfns.c (time_overflow): Now extern.
11605 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
11606 (float-time, Fformat_time_string, Fcurrent_time_string)

11610 (decode_time_components, lisp_seconds_argument): New functions.
11611 (make_time): Now static.
11612 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11613 Report an error if the time is invalid, rather than having the caller
11616 * fileio.c: Include <stat-time.h>
11617 (Fcopy_file): Copy higher-resolution time stamps.
11618 Prefer to set the time stamp via a file descriptor if that works.
11619 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11620 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11621 (Fvisited_file_modtime, Fset_visited_file_modtime):
11622 Support higher-resolution time stamps.
11624 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11626 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11628 * image.c (prepare_image_for_display, clear_image_cache)
11629 (lookup_image): Port to higer-resolution time stamps.
11631 * keyboard.c (start_polling, bind_polling_period):
11632 Check for time stamp overflow.
11633 (read_char, kbd_buffer_get_event, timer_start_idle)
11634 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11635 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11636 Port to higher-resolution time stamps. Do not assume time_t is signed.
11637 (decode_timer): New function. Timers are now vectors of length 9,
11638 not 8, to accommodate the picosecond component.
11639 (timer_check_2): Use it.
11641 * nsterm.m (select_timeout, timeval_subtract): Remove.
11642 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11643 as they're a bit more accurate and handle overflow better.
11644 (ns_select): Change prototype to be compatible with pselect.
11645 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11646 * nsterm.h (ns_select): Adjust prototype.
11648 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11649 us-resolution time stamps.
11650 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11652 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11654 * lisp.h (time_overflow): New decl.
11655 (wait_reading_process_output): First arg is now intmax_t, not int,
11656 to accommodate larger waits.
11658 * process.h (struct Lisp_Process.read_output_delay):
11659 Now counts nanoseconds, not microseconds.
11660 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11662 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11663 (wait_reading_process_output):
11664 Port to ns-resolution time stamps.
11665 (Faccept_process_output, wait_reading_process_output):
11666 Check for time stamp overflow. Do not assume time_t is signed.
11667 (select_wrapper): Remove; we now use pselect.
11668 (Fprocess_attributes): Now generates ns-resolution time stamps.
11670 * sysdep.c: Include utimens.h. Don't include utime.h
11671 or worry about struct utimbuf; gnulib does that for us now.
11672 (gettimeofday): Remove; gnulib provides a substitute.
11673 (make_timeval): New function.
11674 (set_file_times): Now sets ns-resolution time stamps.
11675 New arg FD; all uses changed.
11676 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11677 (system_process_attributes):
11678 Now returns ns-resolution time stamp. All uses changed.
11679 Check for time stamp overflow.
11681 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11682 provides a substitute now.
11684 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11685 since it guarantees struct timespec.
11686 (EMACS_TIME): Now struct timespec, so that we can support
11687 ns-resolution time stamps.
11688 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11689 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11690 (EMACS_USECS): Remove.
11691 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11692 so multiply the arg by 1000 before storing it.
11693 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11695 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11696 Port to ns-resolution time stamps.
11697 (EMACS_TIME_NEG_P): Remove; replaced by....
11698 (EMACS_TIME_SIGN): New macro.
11699 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
11700 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

11702 (make_timeval, make_lisp_time, decode_time_components): New decls.
11703 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11704 that it mishandled time_t overflow. You can't compare by subtracting!
11705 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11706 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11708 * term.c: Include <sys/time.h>.
11709 (timeval_to_Time): New function, for proper overflow wraparound.
11710 (term_mouse_position, term_mouse_click): Use it.
11712 * undo.c (record_first_change): Support higher-resolution time stamps
11713 in the undo buffer.
11714 (Fprimitive_undo): Use them when restoring time stamps.
11716 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11717 (w32_get_internal_run_time):
11718 Port to higher-resolution Emacs time stamps.
11719 (ltime): Now accepts single 64-bit integer, as that's more convenient
11722 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11724 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,

12170 character of length 2: it would truncate after X's first byte
12171 rather than including all of X.

12188 (temacs$(EXEEXT)): Disable memory randomization for the temacs
12189 binary via PaX flags if the paxctl utility is available.
12190 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
12191 Restore PaX flags to their default. (Bug#11398)

12200 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
12201 (note_mode_line_or_margin_highlight): If there is no help echo,
12202 use mode-line-default-help-echo. Handle the case where the mouse
12203 position is past the end of the mode line string.
12205 * buffer.c (buffer_local_value_1): New function, split from
12206 Fbuffer_local_value; can return Qunbound.
12207 (Fbuffer_local_value): Use it.
12208 (Vmode_line_format): Docstring tweaks.

12222 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12224 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12225 Convert pctcpu and pctmem to Lisp float properly.
12226 Let the compiler fold better, as 100.0/0x8000 is exact.
12228 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
12230 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
12233 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

12237 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
12239 For a 'struct window', replace some Lisp_Object fields to
12240 bitfields where appropriate, remove unused fields.
12241 * window.h (struct window): Remove unused 'last_mark_x' and
12242 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12243 change its type from Lisp_Object to bitfield.
12244 Change type of 'force_start', 'optional_new_start',
12245 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
12246 fields from Lisp_Object to bitfield. Adjust users accordingly.
12248 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12250 Pacify gcc -Wdouble-precision when using Xaw.
12251 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
12252 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12253 Use 'float' consistently, rather than 'float' in most places
12254 and 'double' in a couple of places.
12256 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12258 * xdisp.c (handle_stop): Detect whether we have overlay strings
12259 loaded by testing it->current.overlay_string_index to be
12260 non-negative, instead of checking whether n_overlay_strings is
12261 positive. (Bug#11587)
12263 2012-05-31 Chong Yidong <cyd@gnu.org>
12265 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
12267 * doc.c (Fsubstitute_command_keys): Doc fix.
12269 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12271 * search.c (search_buffer): Remove calls to
12272 r_alloc_inhibit_buffer_relocation, as it is now called by
12273 maybe_unify_char, which was the cause of relocation of buffer text
12276 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12278 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12279 for the duration of call to load_charset, to avoid problems with
12280 callers of maybe_unify_char that access buffer text through C
12283 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12284 decrement the inhibition flag, instead of just setting or
12287 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12289 Remove obsolete '#define static' cruft.
12290 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12291 This #undef was "temporary" in 2000; it is no longer needed
12292 now that '#define static' has gone away.
12293 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12294 (gray_bitmap_bits): Remove; no longer needed.
12295 All uses replaced with definiens.
12296 * xterm.c: Include "bitmaps/gray.xbm".
12298 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
12300 Clean up __executable_start, monstartup when --enable-profiling.
12301 The following changes affect the code only when profiling.
12302 * dispnew.c (__executable_start): Rename from safe_bcopy.
12303 Define only on platforms that need it.
12304 * emacs.c: Include <sys/gmon.h> when profiling.
12305 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
12306 (__executable_start): Remove decl, since lisp.h does it now.
12307 (safe_bcopy): Remove decl; no longer has that name.
12308 (main): Coalesce #if into single bit of code, for simplicity.
12309 Cast pointers to uintptr_t, since standard libraries want integers
12311 * lisp.h (__executable_start): New decl.
12313 2012-05-31 Glenn Morris <rgm@gnu.org>
12315 * image.c (Fimagemagick_types): Doc fix.
12317 2012-05-30 Jim Meyering <meyering@redhat.com>
12319 * callproc.c (Fcall_process_region): Include directory component

12336 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
12338 Do not create empty overlays with the evaporate property (Bug#9642).
12339 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12340 Bug#9642, but explicitly check that the buffer the overlay would
12341 be moved to is live and rearrange lines to make sure that errors
12342 will not put the overlay in an inconsistent state.
12343 (Fdelete_overlay): Cosmetics.
12345 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12347 * w32term.c (my_bring_window_to_top): New function.
12348 (x_raise_frame): Use handle returned by DeferWindowPos, which
12349 could be different from the original one.
12350 Call my_bring_window_to_top instead of my_set_foreground_window.
12353 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
12354 by calling BringWindowToTop.

12359 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12361 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12362 This avoids undefined behavior that might cause the eassert
12363 to not catch an out-of-range value.
12365 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12367 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
12368 Update dependencies.
12370 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12372 * bidi.c (bidi_mirror_char): Fix last change.
12374 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
12376 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
12377 when referring to sectname field in printf format.
12379 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
12381 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12382 Only r_alloc_inhibit_buffer_relocation needed to be added;
12383 the others were already declared.
12385 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12386 before checking whether it's out of range. Put the check inside
12388 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12390 2012-05-27 Ken Brown <kbrown@cornell.edu>
12392 * callproc.c (Fcall_process): Restore a line that was accidentally
12393 commented out in the 2011-02-13 change (bug#11547).
12395 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12397 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12398 defined on ralloc.c.
12400 * buffer.c [REL_ALLOC]: Remove prototypes of
12401 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12402 they are now on lisp.h.
12404 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12406 * search.c (search_buffer): Use it to inhibit relocation of buffer
12407 text while re_search_2 is doing its job, because re_search_2 is
12408 passed C pointers to buffer text. (Bug#11519)
12410 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12411 Update value to 24.
12413 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12414 state after an additional call to move_it_in_display_line_to, keep
12415 the values of it->max_ascent and it->max_descent found for the
12417 (pos_visible_p): Revert the comparison against bottom_y to what it
12418 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12421 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12423 Fix coding-related core dumps with gcc -ftrapv.
12424 The code was computing A - B, where A and B are pointers, and B is
12425 random garbage. This can lead to core dumps on platforms that
12426 have special pointer registers, and it also leads to core dumps on
12427 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12428 A - B only when B is initialized properly.
12429 * coding.c (coding_set_source, coding_set_destination): Return void.
12430 (coding_change_source, coding_change_destinations): New functions,
12431 with the old behaviors of coding_set_source and coding_set_destination.
12432 All callers that need an offset changed to use these new functions.
12434 2012-05-26 Glenn Morris <rgm@gnu.org>
12436 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
12438 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12440 Extend mouse support on W32 text-mode console.
12441 * xdisp.c (draw_row_with_mouse_face):
12442 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12444 * w32console.c: Include window.h.
12445 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12447 (initialize_w32_display): Initialize mouse-highlight data.
12449 * w32inevt.c: Include termchar.h and window.h.
12450 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12451 moves, call note_mouse_highlight. If help_echo changed, call
12452 gen_help_event to produce help-echo message in the echo area.
12453 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12456 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12458 * lread.c (read1): Simplify slightly to avoid an overflow warning
12459 with GCC 4.7.0 on x86-64.
12461 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12463 * bidi.c (bidi_mirror_char): Revert last change: an int is
12464 definitely wide enough here.
12466 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12468 Fix integer width and related bugs (Bug#9874).
12469 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
12470 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
12471 (string_bytes, check_sblock, allocate_string_data):
12472 (compact_small_strings, Fmake_bool_vector, make_string)
12473 (make_unibyte_string, make_multibyte_string)
12474 (make_string_from_bytes, make_specified_string)
12475 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
12476 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
12478 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12479 (allocate_pseudovector):
12480 Use int, not EMACS_INT, where int is wide enough.
12481 (inhibit_garbage_collection, Fgarbage_collect):
12482 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12483 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12484 int might not be wide enough.
12485 (bidi_cache_search, bidi_cache_find, bidi_init_it)
12486 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
12487 (bidi_at_paragraph_end, bidi_find_paragraph_start)
12488 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
12489 (bidi_level_of_next_char, bidi_move_to_visually_next):
12490 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12491 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
12492 (Fkill_buffer, Fset_buffer_major_mode)
12493 (advance_to_char_boundary, Fbuffer_swap_text)
12494 (Fset_buffer_multibyte, overlays_at, overlays_in)
12495 (overlay_touches_p, struct sortvec, record_overlay_string)
12496 (overlay_strings, recenter_overlay_lists)
12497 (adjust_overlays_for_insert, adjust_overlays_for_delete)
12498 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
12499 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
12500 (Foverlay_recenter, last_overlay_modification_hooks_used)
12501 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
12502 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12503 (validate_region): Omit unnecessary test for b <= e,
12504 since that's guaranteed by the previous test.
12505 (adjust_overlays_for_delete): Avoid pos + length overflow.
12506 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12507 (report_overlay_modification):
12508 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12509 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12510 Omit pointer cast, which isn't needed anyway, and doesn't work
12511 after the EMACS_INT -> ptrdiff_t change.
12512 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12513 * buffer.h: Adjust decls to match defn changes elsewhere.
12514 (struct buffer_text, struct buffer):
12515 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12516 Use EMACS_INT, not int, where int might not be wide enough.
12517 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12518 not int, to avoid needless 32-bit limit on 64-bit hosts.
12519 (exec_byte_code): Use tighter memory-full test, one that checks
12520 for alloca overflow. Don't compute the address of the object just
12521 before an array, as that's not portable. Use EMACS_INT, not
12522 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12523 * callint.c (Fcall_interactively):
12524 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12525 * callproc.c (call_process_kill, Fcall_process):
12526 Don't assume pid_t fits into an Emacs fixnum.
12527 (call_process_cleanup, Fcall_process, child_setup):
12528 Don't assume pid_t fits into int.
12529 (call_process_cleanup, Fcall_process, delete_temp_file)
12530 (Fcall_process_region):
12531 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12532 (Fcall_process): Simplify handling of volatile integers.
12533 Use int, not EMACS_INT, where int will do.
12534 * casefiddle.c (casify_object, casify_region, operate_on_word)
12535 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
12536 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12537 (casify_object): Avoid integer overflow when overallocating buffer.
12538 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12539 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12540 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12541 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12542 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
12543 integers are now checked earlier. All uses replaced with XINT.
12545 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12546 For CCL_MapSingle, check that content and value are in int range.
12547 (ccl_driver, Fregister_code_conversion_map):
12548 Check that Vcode_version_map_vector is a vector.
12549 (resolve_symbol_ccl_program): Check that vector header is in range.
12550 Always copy the vector, so that we can check its contents reliably
12551 now rather than having to recheck each instruction as it's being
12552 executed. Check that vector words fit in 'int'.
12553 (ccl_get_compiled_code, Fregister_ccl_program)
12554 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12555 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12556 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12557 contents are in range.
12558 (Fccl_execute_on_string): Check that status is in range.
12559 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12560 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12561 Accept and return EMACS_INT, not int, because callers can pass values
12562 out of 'int' range.
12563 (c_string_width, strwidth, lisp_string_width, chars_in_text)
12564 (multibyte_chars_in_text, parse_str_as_multibyte)
12565 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
12566 (str_as_unibyte, str_to_unibyte, string_count_byte8)
12567 (string_escape_byte8, Fget_byte):
12568 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12569 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12570 avoid mishandling large integers.
12571 * character.h: Adjust decls to match defn changes elsewhere.
12572 * charset.c (load_charset_map_from_file, find_charsets_in_text)
12573 (Ffind_charset_region):
12574 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12575 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
12576 (load_charset_map_from_vector, Fdefine_charset_internal):
12577 Don't assume fixnum fits in int.
12578 (load_charset_map_from_vector, Fmap_charset_chars):
12579 Remove now-unnecessary CHECK_NATNUMs.
12580 (Fdefine_charset_internal): Check ranges here, more carefully.
12581 Don't rely on undefined behavior with signed left shift overflow.
12582 Don't assume unsigned int fits into fixnum, or that fixnum fits
12583 into unsigned int. Don't require max_code to be a valid fixnum;
12584 that's not true for gb10830 4-byte on a 32-bit host. Allow
12585 invalid_code to be a cons, for the same reason. Require code_offset
12586 to be a character. Avoid int overflow if max_char is close
12588 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12589 this is intended anyway and avoids some undefined behavior.

13260 (handle_one_xevent): NATNUMP can eval its arg twice.
13261 (x_connection_closed):
13262 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13263 * xterm.h: Adjust decls to match defn changes elsewhere.
13264 (struct scroll_bar): Use struct vectorlike_header
13265 rather than rolling our own approximation.
13266 (SCROLL_BAR_VEC_SIZE): Remove; not used.
13268 2012-05-25 Glenn Morris <rgm@gnu.org>
13270 * lisp.mk (lisp): Update for more files being compiled now.
13272 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
13274 * lread.c: Remove `read_pure' which makes no difference.
13275 (read_pure): Remove var.
13276 (unreadpure): Remove function.
13277 (readevalloop): Don't call read_list with -1 flag.
13278 (read1, read_vector): Don't test read_pure any more.
13279 (read_list): Simplify.
13281 * fileio.c, character.h: Minor style tweaks.
13283 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
13285 * window.h (clip_changed): Remove useless declaration.
13287 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
13289 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
13290 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
13292 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
13295 This directory predates autoconf and is no longer needed nowadays.
13296 Move its few remaining bits of functionality to where they're needed.
13297 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
13298 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
13299 * m/template.h: Remove.
13300 * Makefile.in (M_FILE): Remove. All uses removed.
13301 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
13302 * lisp.h (USE_LSB_TAG):
13303 * mem-limits.h (EXCEEDS_LISP_PTR):
13304 Use VAL_MAX, not VALBITS, in #if.
13305 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
13306 (EMACS_UINT): Define unconditionally now.
13307 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
13308 (BITS_PER_EMACS_INT): New constants, replacing
13309 what used to be in config.h, but not useful in #if.
13310 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
13311 define them any more.
13312 (VAL_MAX): New macro.
13314 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
13315 BITS_PER_EMACS_INT, in #if.
13316 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
13317 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
13318 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
13319 * s/ms-w32.h (DATA_START):
13320 Move here from removed file m/intel386.h.
13321 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
13322 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
13324 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
13326 Assume C89 or later.
13327 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
13328 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
13330 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
13331 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
13332 * textprop.c, tparam.c (NULL): Remove.
13333 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
13334 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
13335 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
13336 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
13337 * xterm.c (input_signal_count): Assume volatile works.
13339 2012-05-21 Ken Brown <kbrown@cornell.edu>
13341 * xgselect.c (xg_select): Fix first argument in call to 'select'
13344 2012-05-20 Ken Brown <kbrown@cornell.edu>
13346 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
13347 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
13349 2012-05-19 Ken Brown <kbrown@cornell.edu>
13351 * xfns.c (x_in_use): Remove `static' qualifier.
13352 * xterm.h (x_in_use): Declare.
13353 * xgselect.c: Include xterm.h.
13354 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
13355 and `display_arg' (bug#9754).
13357 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
13359 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
13361 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
13362 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
13364 2012-05-18 Eli Zaretskii <eliz@gnu.org>
13366 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
13368 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
13369 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
13371 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
13372 reference to image_cache->refcount.
13373 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
13375 2012-05-17 Juri Linkov <juri@jurta.org>
13377 * search.c (Fword_search_regexp, Fword_search_backward)
13378 (Fword_search_forward, Fword_search_backward_lax)
13379 (Fword_search_forward_lax): Move functions to isearch.el
13380 (bug#10145, bug#11381).
13382 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13384 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13386 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13388 * lread.c (init_obarray): Declare Qt and Qnil as special.
13390 2012-05-14 Glenn Morris <rgm@gnu.org>
13392 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13393 Put "libexec" before "bin", for the sake of init_callproc_1.
13395 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13397 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13399 * unexaix.c: Port to more-recent AIX compilers.
13400 (report_error, report_error_1, make_hdr, copy_sym)
13401 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13402 Make arguments const char *, not char *, to avoid violations of C
13403 standard and to fix some AIX warnings reported by Gilles Pion.
13405 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13407 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13408 already have overlays loaded.
13409 (handle_single_display_spec): Before returning without displaying
13410 fringe bitmap, synchronize the bidi iterator with the main display
13411 iterator, by calling iterate_out_of_display_property.
13412 (iterate_out_of_display_property): Detect buffer iteration by
13413 testing that it->string is a Lisp string.
13414 (get_next_display_element): When the current object is exhausted,
13415 and there's something on it->stack, call set_iterator_to_next to
13416 proceed with what's on the stack, instead of returning zero.
13417 (set_iterator_to_next): If called at the end of a Lisp string,
13418 proceed to consider_string_end without incrementing string
13419 position. Don't increment display vector index past the end of
13420 the display vector. (Bug#11417)
13421 (pos_visible_p): Don't report a position visible when move_it_to
13422 stopped at the last line of window, which happens to be scanned
13423 backwards by the bidi iteration. (Bug#11464)
13425 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13427 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13428 and right-margin display specs even if the spec is invalid or we
13429 are on a TTY, and thus unable to display on the fringes.
13430 That's because the text with the property will not be displayed anyway,
13431 so we need to signal to the caller that this is a "replacing"
13432 display spec. This fixes display when the spec is invalid or we
13435 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13437 * unexaix.c (make_hdr): Fix typo in prototype.
13438 This bug broke the build on AIX. Problem reported by Gilles Pion.
13440 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13442 * keyboard.c (kbd_buffer_get_event): Read special events also in
13443 batch mode. (Bug#11415)
13445 2012-05-12 Glenn Morris <rgm@gnu.org>
13447 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13449 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13451 * lisp.mk (lisp): Add newcomment.elc.
13453 2012-05-12 Glenn Morris <rgm@gnu.org>
13455 * Makefile.in (MKDIR_P): New, set by configure.
13456 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13458 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13460 Remove unused function hourglass_started.
13461 * dispextern.h (hourglass_started):
13462 * w32fns.c (hourglass_started):
13463 * xdisp.c (hourglass_started): Remove.
13465 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13467 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13468 Update dependencies.
13470 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13472 * xgselect.c (xg_select): Put maxfds+1 into a var.
13473 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13475 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13477 2012-05-10 Dave Abrahams <dave@boostpro.com>
13479 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13480 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13482 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13484 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13485 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13486 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13487 Initialize xd_registered_buses.
13489 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13491 Untag more efficiently if USE_LSB_TAG.
13492 This is based on a proposal by YAMAMOTO Mitsuharu in
13493 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13494 For an admittedly artificial (nth 8000 longlist) benchmark on
13495 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13496 Emacs's overall text size by 1%.
13497 * lisp.h (XUNTAG): New macro.
13498 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13499 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13500 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13501 * eval.c (Fautoload):
13502 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13503 * frame.h (XFRAME): Use XUNTAG.
13505 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13506 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13507 Remove unportable assumptions about print widths of types like
13509 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13510 intptr_t when converting between pointer and integer, to avoid GCC
13511 warnings about wrong width.
13513 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13515 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13516 stack for each reader_thread, instead of defaulting to 8MB
13517 determined by the linker. This avoids failures in creating
13518 subprocesses on Windows 7, see the discussion in this thread:
13519 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13521 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13523 Fix up display of the *Minibuf-0* buffer in the mini window.
13524 * keyboard.c (read_char): Don't clear the echo area if there's no
13526 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13527 contents of *Minibuf-0*) if there's no message displayed in its stead.
13529 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13531 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13534 2012-05-06 Chong Yidong <cyd@gnu.org>
13536 * lisp.mk (lisp): Update.
13538 2012-05-05 Jim Meyering <meyering@redhat.com>
13540 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13542 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13544 * data.c (PUT_ERROR): New macro.
13545 (syms_of_data): Use it. Add new error type `user-error'.
13546 * undo.c (user_error): New function.
13547 (Fprimitive_undo): Use it.
13548 * print.c (print_error_message): Adjust print style for `user-error'.
13549 * keyboard.c (user_error): New function.
13550 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13552 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13554 Do not limit current-time-string to years 1000..9999.
13555 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13556 (Fcurrent_time_string): Support any year that is supported by the
13557 underlying localtime representation. Don't use asctime, as it
13558 has undefined behavior for years outside the range -999..9999.
13560 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13562 Fix race conditions involving setenv, gmtime, localtime, asctime.
13563 Without this fix, interrupts could mess up code that uses these
13564 nonreentrant functions, since setting TZ invalidates existing
13565 tm_zone or tzname values, and since most of these functions return
13566 pointers to static storage.
13567 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13568 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13569 Grow the critical sections to include not just invoking
13570 localtime/gmtime, but also accessing these functions' results
13571 including their tm_zone values if any, and any related TZ setting.
13572 (format_time_string): Last arg is now struct tm *, not struct tm **,
13573 so that the struct tm is saved in the critical section.
13574 All callers changed. Simplify allocation of initial buffer, partly
13575 motivated by the fact that memory allocation needs to be outside
13576 the critical section.
13578 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13580 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13581 with RESET_INTERVAL.
13583 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13584 Remove duplicated buffer name initialization.
13586 2012-05-02 Jim Meyering <jim@meyering.net>
13588 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13590 * xfns.c (x_window): Use xstrdup (Bug#11375).
13592 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13594 * xdisp.c (pos_visible_p): If already at a newline from the
13595 display string before the 'while' loop, don't walk back the glyphs
13596 from it3.glyph_row. Solves assertion violation when the display
13597 string begins with a newline (egg.el). (Bug#11367)
13599 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13601 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13604 2012-05-01 Glenn Morris <rgm@gnu.org>
13606 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13607 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13608 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13609 All were removed before 23.1.
13611 * dispnew.c: Remove HAVE_LIBNCURSES test;
13612 it is always true on relevant platforms.
13614 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13615 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13617 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13619 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13621 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13622 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13625 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13627 Do not avoid creating empty evaporating overlays (Bug#9642).
13628 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13629 That is, do not delete an evaporating overlay if it becomes
13630 empty after its bounds are adjusted to fit within its buffer.
13631 This fix caused other problems, and I'm reverting it until we get
13632 to the bottom of them.
13634 2012-04-27 Chong Yidong <cyd@gnu.org>
13636 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13638 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13640 * xdisp.c (pos_visible_p): If the window start position is beyond
13641 ZV, start the display from buffer beginning. Prevents assertion
13642 violation in init_iterator when the minibuffer window is scrolled
13643 via the scroll bar.
13645 * window.c (window_scroll_pixel_based): Likewise.
13647 2012-04-27 Chong Yidong <cyd@gnu.org>
13649 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13651 2012-04-27 Glenn Morris <rgm@gnu.org>
13653 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13654 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13656 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13658 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13659 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13661 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13663 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13664 display element, check also the underlying string or buffer
13665 character. (Bug#11341)
13667 * w32menu.c: Include w32heap.h.
13668 (add_menu_item): If the call to AppendMenuW (via
13669 unicode_append_menu) fails, disable Unicode menus only if we are
13670 running on Windows 9X/Me.
13672 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13674 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13675 (xgetint): Add missing shift for LSB tags.
13677 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13679 * keyboard.c (read_char): Don't wipe echo area for select window
13680 events: These might get delayed via `mouse-autoselect-window'
13683 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13685 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13686 manipulation of :loaded-from data.
13688 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13690 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13691 now a cons (bug#11311).
13693 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13695 Do not create empty overlays with the evaporate property (Bug#9642).
13696 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13697 if it becomes empty after its bounds are adjusted to fit within
13698 its buffer. Without this fix, in a nonempty buffer (let ((o
13699 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13700 yields an empty overlay that has the evaporate property, which is
13701 not supposed to happen.
13703 Fix minor GTK3 problems found by static checking.

13905 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13906 (NEED_MEM_INSERT): New macro.
13907 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13908 Remove one incorrect comment and fix another.

13975 2012-04-11 Daniel Colascione <dancol@dancol.org>
13977 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13978 against is gone. It's better to use vfork now so that when Cygwin
13979 gains a new, working vfork, we use it automatically (bug#10398).
13981 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

14034 * minibuf.c (Fread_variable): Callers changed.
14036 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14038 * xdisp.c (set_cursor_from_row): If the display string appears in
14039 the buffer at position that is closer to point than the position
14040 after the display string, display the cursor on the first glyph of
14041 the display string. Fixes cursor display when a 'display' text
14042 property immediately follows invisible text. (Bug#11094)
14044 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14046 composite.c: use 'double' consistently
14047 * composite.c (get_composition_id): Use 'double' consistently
14048 instead of converting 'float' to 'double' and vice versa; this is
14049 easier to understand and avoids a GCC warning.
14051 2012-04-09 Glenn Morris <rgm@gnu.org>

14098 [!WINDOWSNT]: New macros.
14099 (init_libxml2_functions, libxml2_loaded_p): New functions.

14103 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14105 (Flibxml_parse_html_region, Flibxml_parse_xml_region):

14118 point, use it.vpos to compute how many lines to backtrack after
14119 move_it_to point. (Bug#11133)
14121 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14123 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14124 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14125 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14126 macros related to unification of CJK characters. For the details,
14127 see the discussion following the message here:

14134 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14136 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
14137 instead of alloca. (Bug#11138)
14139 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
14141 * w32menu.c (is_simple_dialog): Properly check lisp types.
14144 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14146 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14147 position we get to after a call to move_it_to fails the
14148 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14149 only if we wind up in a string from display property. (Bug#11063)
14151 * window.c (Fdelete_other_windows_internal): Invalidate the row
14152 and column information about mouse highlight, so that redisplay
14153 restores it after reallocating the glyph matrices. (Bug#7464)
14155 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14156 string comes from a `display' text property, use the buffer
14157 position of that property as if we actually saw that position in
14159 (move_it_by_lines): Remove the assertion that
14160 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14161 violated when there's a before-string at the beginning of a line.
14164 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14166 * xdisp.c (append_space_for_newline): If the default face was
14167 remapped, use the remapped face for the appended newline.
14168 (extend_face_to_end_of_line): Use the remapped default face for
14169 extending the face to the end of the line.
14170 (display_line): Call extend_face_to_end_of_line when the default
14171 face was remapped. (Bug#11068)
14173 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14175 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
14177 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14179 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
14181 2012-03-27 Glenn Morris <rgm@gnu.org>
14183 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
14186 2012-03-26 Kenichi Handa <handa@m17n.org>
14188 * dispextern.h (struct glyph): Fix previous change. Change the
14189 bit length of glyphless.ch to 25 (Bug#11082).
14191 2012-03-26 Chong Yidong <cyd@gnu.org>
14193 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14194 (command_loop_1): Use it; inhibit selection update for
14195 handle-select-window too (Bug#8996).
14197 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
14199 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14201 2012-03-25 Kenichi Handa <handa@m17n.org>
14203 * dispextern.h (struct glyph): Change the bit length of
14204 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14206 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14208 * s/ms-w32.h (tzname): Include time.h before redirecting to
14209 _tzname. Fixes the MSVC build. (Bug#9960)
14211 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
14213 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
14216 * xterm.c (XTread_socket): Only modify handling_signal if
14217 !SYNC_INPUT. (Bug#11080)
14219 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14221 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14222 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14223 when fetching a multibyte character consumes more bytes than
14224 CHAR_BYTES returns, due to unification of CJK characters in
14225 string_char. (Bug#11073)
14227 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14229 * process.c (wait_reading_process_output): Handle pty disconnect
14230 by refraining from sending oneself a SIGCHLD (bug#10933).
14232 2012-03-22 Chong Yidong <cyd@gnu.org>
14234 * dispextern.h (struct it): New member string_from_prefix_prop_p.
14236 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
14237 Mark string as coming from a prefix property.
14238 (handle_face_prop): Use default face for prefix strings (Bug#4281).
14239 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
14241 2012-03-21 Chong Yidong <cyd@gnu.org>
14243 * xfaces.c (Vface_remapping_alist): Doc fix.
14245 2012-03-20 Eli Zaretskii <eliz@gnu.org>
14247 * w32proc.c (Fw32_set_console_codepage)
14248 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
14251 2012-03-20 Chong Yidong <cyd@gnu.org>
14253 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
14254 to reflect default non-nil value of redisplay-dont-pause.
14256 2012-03-19 Kenichi Handa <handa@m17n.org>
14258 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
14259 it fit in a valid range (Bug#11003).
14261 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14263 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14264 that is not from display property, accept the row as a "cursor
14265 row" if one of the string's character has a non-nil `cursor'
14266 property. Fixes cursor positioning when there are newlines in
14267 overlay strings, e.g. in icomplete.el. (Bug#11035)
14269 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14271 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14273 2012-03-12 Chong Yidong <cyd@gnu.org>
14275 * eval.c (inhibit_lisp_code): Rename from
14276 inhibit_window_configuration_change_hook; move from window.c.
14278 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14279 * window.c (run_window_configuration_change_hook)
14280 (syms_of_window): Callers changed.
14282 2012-03-11 Chong Yidong <cyd@gnu.org>
14284 * keymap.c (Fkey_description): Doc fix (Bug#9700).
14286 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
14288 2012-03-10 Chong Yidong <cyd@gnu.org>
14290 * frame.c (other_visible_frames): Don't assume the selected frame
14291 is visible (Bug#10955).
14293 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
14295 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
14297 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
14299 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
14300 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14303 2012-03-03 Glenn Morris <rgm@gnu.org>
14305 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14307 2012-03-02 Eli Zaretskii <eliz@gnu.org>
14309 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
14310 position past the first glyph_row that ends at ZV. (Bug#10902)
14311 (redisplay_window, next_element_from_string): Fix typos in
14313 (redisplay_window): Pass to move_it_vertically the margin in
14314 pixels, not in screen lines.
14316 2012-03-02 Glenn Morris <rgm@gnu.org>
14318 * buffer.c (buffer-list-update-hook): Doc fix.
14320 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14322 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14323 push_it before setting up the iterator for the first overlay
14324 string, even if we have an empty string loaded.
14325 (next_overlay_string): If there's an empty string on the iterator
14326 stack, pop the stack. (Bug#10903)
14328 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14330 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14331 Suggested by Stefan Monnier in
14332 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14333 * alloc.c (widen_to_Lisp_Object): New static function.
14334 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14335 and widening them to Lisp_Objects. This would work even if
14336 USE_LSB_TAG is defined and wide integers are used, which might
14337 happen in a future version of Emacs.
14339 2012-02-25 Chong Yidong <cyd@gnu.org>
14341 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
14344 * xselect.c (Fx_selection_exists_p): Doc fix.
14345 (x_clipboard_manager_save_all): Print an informative message
14346 before saving to clipboard manager.
14348 2012-02-24 Chong Yidong <cyd@gnu.org>
14350 * keyboard.c (process_special_events): Handle all X selection
14351 requests in kbd_buffer, not just the next one (Bug#8869).
14353 2012-02-23 Chong Yidong <cyd@gnu.org>
14355 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14356 call when setting menu-bar-lines and tool-bar-lines parameters.
14357 (unwind_create_frame_1): New helper function.
14359 * window.c (inhibit_window_configuration_change_hook): New var.
14360 (run_window_configuration_change_hook): Obey it.
14361 (syms_of_window): Initialize it.
14363 2012-02-22 Chong Yidong <cyd@gnu.org>
14365 * xterm.c (x_draw_image_relief): Add missing type check for
14366 Vtool_bar_button_margin (Bug#10743).
14368 2012-02-21 Chong Yidong <cyd@gnu.org>
14370 * fileio.c (Vfile_name_handler_alist): Doc fix.
14372 * buffer.c (Fget_file_buffer): Protect against invalid file
14373 handler return value.
14375 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
14377 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
14378 when computing $valmask.
14380 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14381 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14382 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14383 It's useless in that case, and it can cause problems on hosts
14384 that allocate halves of EMACS_INT values separately.
14385 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14386 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14387 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14388 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14389 it avoids undefined behavior on hosts where shifting right by more
14390 than the word width has undefined behavior.
14392 2012-02-19 Chong Yidong <cyd@gnu.org>
14394 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14395 (Funhandled_file_name_directory, Ffile_name_as_directory)
14396 (Fdirectory_file_name, Fexpand_file_name)
14397 (Fsubstitute_in_file_name): Protect against invalid file handler
14398 return values (Bug#10845).
14400 2012-02-18 Eli Zaretskii <eliz@gnu.org>
14402 * .gdbinit (pitx): Fix incorrect references to fields of the
14405 2012-02-17 Chong Yidong <cyd@gnu.org>

14409 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
14411 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
14412 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14414 2012-02-15 Chong Yidong <cyd@gnu.org>
14416 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14417 marked as special. Also, starting docstrings with * is obsolete.
14419 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
14421 * gnutls.c (emacs_gnutls_write): Fix last change.
14423 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
14425 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
14428 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
14430 * keymap.c (Fsingle_key_description): Handle char ranges.
14432 2012-02-12 Chong Yidong <cyd@gnu.org>
14434 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14435 as that creates a dangerous corner case.
14437 * window.c (Fdelete_window_internal): Invalidate the mouse
14438 highlight (Bug#9904).
14440 2012-02-12 Glenn Morris <rgm@gnu.org>
14442 * xselect.c (Fx_own_selection_internal)
14443 (Fx_get_selection_internal, Fx_disown_selection_internal)
14444 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
14445 * nsselect.m (Fx_own_selection_internal)
14446 (Fx_disown_selection_internal, Fx_selection_exists_p)
14447 (Fx_selection_owner_p, Fx_get_selection_internal):
14448 Sync docs and argument specs with the xselect.c versions.
14450 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
14452 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
14454 2012-02-11 Eli Zaretskii <eliz@gnu.org>
14456 * w32select.c (Fx_selection_exists_p): Sync doc string and
14457 argument list with xselect.c. (Bug#10783)
14459 * w16select.c (Fx_selection_exists_p): Sync doc string and
14460 argument list with xselect.c. (Bug#10783)
14462 2012-02-10 Glenn Morris <rgm@gnu.org>
14464 * fns.c (Fsecure_hash): Doc fix.
14466 2012-02-09 Kenichi Handa <handa@m17n.org>
14468 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
14470 2012-02-07 Chong Yidong <cyd@gnu.org>
14472 * buffer.c (Fbuffer_local_variables)
14473 (buffer_lisp_local_variables): Handle unbound vars correctly;
14474 don't let Qunbound leak into Lisp.
14476 2012-02-07 Glenn Morris <rgm@gnu.org>
14478 * image.c (Fimagemagick_types): Doc fix.
14480 * image.c (imagemagick-render-type): Change it from a lisp object
14481 to an integer. Move the doc here from the lisp manual.
14482 Treat all values not equal to 0 the same.
14484 2012-02-06 Chong Yidong <cyd@gnu.org>
14486 * doc.c (store_function_docstring): Avoid applying docstring of
14487 alias to base function (Bug#2603).
14489 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>

14494 2012-02-04 Chong Yidong <cyd@gnu.org>
14496 * nsterm.m: Declare a global (Bug#10694).
14498 2012-02-04 Eli Zaretskii <eliz@gnu.org>
14500 * w32.c (get_emacs_configuration_options):
14501 Include --enable-checking, if specified, in the return value.
14503 2012-02-04 Martin Rudalics <rudalics@gmx.at>
14505 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
14506 after rounding frame sizes. (Bug#9723)
14508 2012-02-04 Eli Zaretskii <eliz@gnu.org>
14510 * keyboard.c (adjust_point_for_property): Don't position point
14511 before BEGV. (Bug#10696)
14513 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
14515 Handle overflow when computing char display width (Bug#9496).
14516 * character.c (char_width): Return EMACS_INT, not int.
14517 (char_width, c_string_width): Check for overflow when
14518 computing the width; this is possible now that individual
14519 characters can have unbounded width. Problem introduced
14520 by merge from Emacs 23 on 2012-01-19.
14522 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
14524 * dbusbind.c (Fdbus_register_method): Mention the return value
14525 :ignore in the docstring.
14527 2012-02-02 Glenn Morris <rgm@gnu.org>
14529 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
14531 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
14532 Unconditionally set to t. (Bug#10673)

14537 2012-02-02 Kenichi Handa <handa@m17n.org>
14539 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
14540 0, do not call append_composite_glyph.
14542 2012-02-02 Kenichi Handa <handa@m17n.org>
14544 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
14546 (x_produce_glyphs): If the component of a composition is a null
14547 string, set it->pixel_width to 1 to avoid zero-width glyph.
14549 2012-02-01 Eli Zaretskii <eliz@gnu.org>
14551 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
14552 first 2 arguments are identical. This makes inserting large
14553 output from a subprocess an order of magnitude faster on
14554 MS-Windows, where all sbrk'ed memory is always contiguous.
14556 2012-01-31 Glenn Morris <rgm@gnu.org>
14558 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

14594 2012-01-21 Chong Yidong <cyd@gnu.org>
14596 * floatfns.c (Fcopysign): Make the second argument non-optional,
14597 since nil is not allowed anyway.
14599 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
14601 * process.c (read_process_output): Use p instead of XPROCESS (proc).
14602 (send_process): Likewise.
14604 2012-01-19 Martin Rudalics <rudalics@gmx.at>
14606 * window.c (save_window_save, Fcurrent_window_configuration)
14607 (Vwindow_persistent_parameters): Do not use Qstate.
14608 Rewrite doc-strings.
14610 2012-01-19 Kenichi Handa <handa@m17n.org>
14612 * character.c (char_width): New function.
14613 (Fchar_width, c_string_width, lisp_string_width):
14614 Use char_width (Bug#9496).
14616 2012-01-16 Martin Rudalics <rudalics@gmx.at>
14618 * window.c (Vwindow_persistent_parameters): New variable.
14619 (Fset_window_configuration, save_window_save): Handle persistent

15173 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15174 is set, removing the need for VIRT_ADDRESS_VARIES.
15175 (PURE_P): Use a more-efficient implementation that needs just one
15176 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
15177 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
15178 to 4 (xorl, subq, cmpq, setbe).
15179 * alloc.c (pure): Always extern now, since that's the
15180 VIRT_ADDR_VARIES behavior.

15182 consistency with the new puresize.h.
15183 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
15184 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

15192 behave as if the cursor position were at the window margin.
15194 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15195 and the cursor position is out of bounds, behave as if the cursor
15196 position were at the window margin. (Bug#10075)
15198 2011-11-18 Chong Yidong <cyd@gnu.org>
15200 * window.c (Fwindow_combination_limit): Make first argument

15222 compute_line_metrics.
15223 (compute_line_metrics): Call row_hash, instead of computing the
15226 * dispnew.c (verify_row_hash): Call row_hash for computing the
15227 hash code of a row, instead of duplicating code from xdisp.c.
15229 * dispextern.h (row_hash): Add prototype.
15231 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

15267 2011-11-14 Eli Zaretskii <eliz@gnu.org>
15269 * xdisp.c (display_line): Move the call to
15270 highlight_trailing_whitespace before the call to
15271 compute_line_metrics, since the latter needs to see the final
15272 faces of all the glyphs to compute ROW's hash value.
15273 Fixes assertion violations in row_equal_p. (Bug#10035)
15275 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
15277 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
15278 just return (bug#10044).

15282 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
15283 with user-defined heap size. Bump the default size of the temacs

15287 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
15288 current_matrix and desired_matrix. (Bug#9990)
15289 (verify_row_hash) [XASSERTS]: New function.

15336 Avoid some portability problems by eschewing 'extern inline' functions.
15337 The trivial performance wins aren't worth the portability hassles; see

15406 * xmenu.c (cleanup_widget_value_tree): New function.
15407 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

15414 (window_box_width, window_box_left, window_box_left_offset)
15415 (window_box_right, window_box_right_offset): Declare extern.
15416 Otherwise, these inline functions do not conform to C99 and
15417 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15418 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15419 * intervals.c (adjust_intervals_for_insertion)

15422 (static_offset_intervals): Remove.
15423 (offset_intervals): Rewrite using the old contents of
15424 static_offset_intervals. The old version didn't conform to C99

15548 2011-11-03 Eli Zaretskii <eliz@gnu.org>
15550 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
15552 * w32fns.c (unwind_create_frame): If needed, free the glyph
15553 matrices of the partially constructed frame. (Bug#9943)
15554 * xfns.c (unwind_create_frame): Likewise.
15556 2011-11-01 Eli Zaretskii <eliz@gnu.org>
15558 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
15559 Don't stop backward scan on the continuation glyph, even though
15560 its CHARPOS is positive.
15561 (mouse_face_from_buffer_pos, note_mouse_highlight):
15562 Rename cover_string to disp_string.
15564 2011-11-01 Martin Rudalics <rudalics@gmx.at>
15566 * window.c (temp_output_buffer_show): Don't use
15567 Vtemp_buffer_show_specifiers.
15568 (Vtemp_buffer_show_specifiers): Remove unused variable.
15570 2011-10-30 Eli Zaretskii <eliz@gnu.org>
15572 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
15573 past the beginning of the current glyph matrix.
15575 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
15577 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
15578 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
15579 HAVE_GTK3 (Bug#9869).
15581 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
15582 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
15584 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
15586 * xterm.c: Declare x_handle_net_wm_state to return int.
15587 (handle_one_xevent): Check if we are iconified but don't have
15588 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
15589 (get_current_wm_state): Return non-zero if not hidden,
15590 check for _NET_WM_STATE_HIDDEN (Bug#9893).
15591 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
15592 (x_handle_net_wm_state): Return what get_current_wm_state returns.
15593 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
15595 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
15597 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
15598 so that this new function doesn't get optimized away by a
15599 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
15601 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
15603 * frame.h (MOUSE_HL_INFO): Remove excess parens.
15605 2011-10-29 Eli Zaretskii <eliz@gnu.org>
15607 Fix the `xbytecode' command.
15608 * .gdbinit (xprintbytestr): New command.
15609 (xwhichsymbols): Rename from `which'; all callers changed.
15610 (xbytecode): Print the byte-code string as well.
15612 2011-10-29 Kim Storm <storm@cua.dk>
15614 * alloc.c (which_symbols): New function.
15616 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
15618 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
15621 2011-10-29 Glenn Morris <rgm@gnu.org>
15623 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
15624 Not clear what it was for, and it causes various bugs. (Bug#9839)
15626 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15628 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
15629 possible random value that matches one of those tested as
15630 condition to clear the mouse face.
15632 2011-10-28 Chong Yidong <cyd@gnu.org>
15634 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
15636 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
15638 * window.c (make_window): Initialize phys_cursor_on_p.
15640 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
15642 * lisp.h (struct Lisp_Symbol): Update comments.
15644 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
15646 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
15648 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15650 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
15651 <oslsachem@gmail.com> for helping to debug this.
15653 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
15654 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
15655 (g_b_init_get_glyph_outline_w): New static variables.
15656 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
15657 (GetGlyphOutlineW_Proc): New typedefs.
15658 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
15659 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
15661 (w32font_open_internal, compute_metrics):
15662 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15663 instead of calling the "wide" APIs directly.
15665 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
15667 * w32.h (syms_of_w32font): Add prototype.
15669 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15671 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
15672 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
15673 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
15674 (Fmove_to_window_line): Doc fix.
15676 2011-10-27 Chong Yidong <cyd@gnu.org>
15678 * process.c (make_process): Set gnutls_state to NULL.
15680 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15681 non-NULL, regardless of GNUTLS_INITSTAGE.
15682 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
15683 an error. Set process slots as soon as we allocate them.
15685 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
15687 2011-10-27 Chong Yidong <cyd@gnu.org>
15689 * gnutls.c (emacs_gnutls_deinit): New function.
15690 Deallocate credentials structures as well as calling gnutls_deinit.
15691 (Fgnutls_deinit, Fgnutls_boot): Use it.
15693 * process.c (make_process): Initialize GnuTLS credentials to NULL.
15694 (deactivate_process): Call emacs_gnutls_deinit.
15696 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15698 * image.c (x_create_x_image_and_pixmap):
15699 * w32.c (sys_rename, w32_delayed_load):
15700 * w32font.c (fill_in_logfont):
15701 * w32reg.c (x_get_string_resource): Silence compiler warnings.
15703 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
15705 * w32fns.c (w32_default_color_map): New function,
15706 extracted from Fw32_default_color_map.
15707 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
15709 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
15711 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
15713 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
15715 * keyboard.c (test_undefined): New function (bug#9751).
15716 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
15718 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
15720 * sysdep.c (init_sys_modes): Fix the check for the controlling
15721 terminal (Bug#6649).
15723 2011-10-20 Eli Zaretskii <eliz@gnu.org>
15725 * dispextern.h (struct bidi_it): New member next_en_type.
15727 * bidi.c (bidi_line_init): Initialize the next_en_type member.
15728 (bidi_resolve_explicit_1): When next_en_pos is valid for the
15729 current character, check also for next_en_type being WEAK_EN.
15730 (bidi_resolve_weak): Don't enter the expensive loop if the current
15731 position is before next_en_pos. Record the bidi type of the first
15732 non-ET, non-BN character we find, in addition to its position.
15733 (bidi_level_of_next_char): Invalidate next_en_type when
15734 next_en_pos is over-stepped.
15736 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15738 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15739 * editfns.c: Rewrite current-time-zone so that it invokes
15740 the equivalent of (format-time-string "%Z") to get the time zone name.
15741 This fixes a bug when the time zone name contains characters that
15742 need converting from the system time locale to Emacs internal format.
15743 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15744 that patch fixed format-time-string to do the conversion, but
15745 I forgot to fix current-time-zone.
15746 (format_time_string): New function, containing most of
15747 what Fformat_time_string used to contain.
15748 (Fformat_time_string): Rewrite in terms of format_time_string.
15749 This doesn't change this function's behavior.
15750 (current-time-zone): Rewrite to use format_time_string.
15751 This fixes the bug reported by Michael Schierl in
15752 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15753 Jason Rumney's 2007-06-07 change worked around this bug, but
15755 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15757 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15759 * xdisp.c (start_display): If the character at POS is displayed
15760 via a display vector, reset IT->current.dpvec_index to zero.
15761 (try_window_reusing_current_matrix): If a line ends in a display
15762 vector or the next line starts in a display vector, continue
15763 redrawing the window even though the character position of
15764 start_row was reached.
15767 2011-10-18 Chong Yidong <cyd@gnu.org>
15769 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15770 with nobreak-char-display too.
15772 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15774 Fix part 3 of bug#9771.
15775 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15776 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15777 non-neutral characters if the current character is a paragraph
15778 separator (a.k.a. Newline). This avoids running the same
15779 expensive loop twice, once when we consume the preceding newline
15780 and the other time when the line actually needs to be displayed.
15781 Avoid the loop when we see neutrals on the base embedding level
15782 following a character whose directionality is the same as the
15783 paragraph's. This avoids running the expensive loop when a line
15784 ends in a long sequence of neutrals, like control characters.
15785 Add assertion against STRONG_AL type. Slightly rearrange code
15786 that determines the type of a neutral given the first non-neutral
15788 (bidi_level_of_next_char): Set next_en_pos to zero when
15789 invalidating its info.
15791 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15793 * xdisp.c (push_display_prop): Determine whether to record string
15794 or buffer position by IT->string, not by IT->method. Allow
15795 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15796 (move_it_vertically_backward): Don't look for character position
15797 immediately after the newline when in a continuation line.
15800 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15802 * window.c (coordinates_in_window): Rewrite and delabelize
15803 vertical border check. (Bug#5357) (Bug#9618)
15805 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15807 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15808 errors in XSetWindowBorder (bug#9310).
15810 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15812 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15813 avoid crash when xmalloc overrun checking is enabled.
15815 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15817 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15818 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15819 cursor motion with <left> and <right> arrow keys.
15821 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15822 some callers set that themselves.
15824 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15826 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15827 display string and the previous row comes from the same string and
15828 is empty. (Bug#9739) (Bug#9738)
15830 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15832 * doc.c (get_doc_string): Encode file name (bug#9735).
15834 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15836 * bidi.c (bidi_level_of_next_char):
15837 * xdisp.c (get_visually_first_element): Remove old incorrect
15838 comments regarding the Unicode Line Separator character.
15840 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15842 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15844 * alloc.c (Fgc_status): Do not access beyond zombies array
15845 boundary if nzombies > MAX_ZOMBIES.
15846 * alloc.c (dump_zombies): Add missing format specifier.
15848 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15850 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15851 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15853 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15854 Some packages use them to denote characters with modifiers.
15856 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15858 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15859 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15860 matching a pp-number. Rename parameter var to var1.
15862 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15864 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15866 2011-10-08 Glenn Morris <rgm@gnu.org>
15868 * callint.c (Fcall_interactively): Give a more explicit error for the
15869 'c' case with a non-character input. (Bug#8479)
15871 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15873 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15875 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15876 lines that are hscrolled on the left.
15878 * dispnew.c (buffer_posn_from_coords): Account for a possible
15879 presence of header-line. (Bug#4426)
15881 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15883 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15884 Don't advertise functionality which we discourage or doesn't work.
15886 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15888 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15889 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15890 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15891 this makes Emacs dump core during garbage collection on rare
15892 occasions. sizeof is obviously inferior to offsetof here, so
15893 stick with offsetof.
15894 (GC_POINTER_ALIGNMENT): New macro.
15895 (mark_memory): Omit 3rd (offset) arg; caller changed.
15896 Don't assume EMACS_INT alignment is the same as pointer alignment.
15898 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15900 * keyboard.c (read_key_sequence_remapped): New var.
15901 (read_key_sequence): Compute remapping in the right buffer.
15902 (command_loop_1): Use read_key_sequence's remapping directly.
15904 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15906 * dired.c (file_name_completion): Don't expand file name.
15907 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15908 before checking file name handler.
15910 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15911 they've been requested explicitly (bug#9591).
15913 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15915 * keymap.c (Fsingle_key_description): Use make_specified_string
15916 instead of build_string to build string from push_key_description.
15919 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15921 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15922 This fixes a Y2038 bug on 64-bit hosts.
15923 * buffer.c (reset_buffer):
15924 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15925 (Fclear_buffer_auto_save_failure):
15926 Use 0, not -1, to represent an unset failure time, since time_t
15927 might not be signed.
15929 Remove dependency on glibc malloc internals.
15930 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15931 Move back here from lisp.h, but with their new implementations.
15932 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15933 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15934 * charset.c (charset_table_init): New static var.
15935 (syms_of_charset): Use it instead of xmalloc. This removes a
15936 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15937 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15938 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15939 Move back to alloc.c.
15940 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15941 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15943 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15945 * nsterm.m (windowDidResize): Call x_set_window_size only when
15946 ns_in_resize is true. Otherwise set pixelwidth/height and
15947 call change_frame_size (Bug#9628).
15949 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15951 Port --enable-checking=all to Fedora 14 x86-64.
15952 * charset.c (syms_of_charset): Also account for glibc malloc's
15953 internal overhead when calculating the initial malloc maximum.
15955 Port --enable-checking=all to Fedora 14 x86.
15956 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15958 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15959 (overrun_check_realloc, overrun_check_free):
15960 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15961 That way, xmalloc returns a properly-aligned pointer even if
15962 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15963 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15964 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15965 into account when calculating the initial malloc maximum.
15966 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15967 Move here from alloc.c, so that charset.c can use it too.
15968 Properly align; the old code wasn't right for common 32-bit hosts
15969 when configured with --enable-checking=all.
15970 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15971 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15973 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15975 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15978 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15980 * xdisp.c (compute_display_string_end): If there's no display
15981 string at CHARPOS, return -1.
15983 * bidi.c (bidi_fetch_char): When compute_display_string_end
15984 returns a negative value, treat the character as a normal
15985 character not covered by a display string. (Bug#9624)
15987 2011-09-28 Juanma Barranquero <lekktu@gmail.com>

15991 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15993 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15994 newline, reseat the iterator instead of bidi-iterating there one
15995 character at a time. (Bug#9610)
15996 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15997 TO_CHARPOS if the bidi iterator is at base embedding level.
15999 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16001 * lread.c (readevalloop): Use correct code for NBSP.

16004 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16006 * dbusbind.c (Fdbus_register_signal): When service is not
16007 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16009 2011-09-25 Glenn Morris <rgm@gnu.org>
16011 * buffer.c (truncate-lines): Doc fix.
16013 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16015 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16016 (Fset_window_next_buffers): Doc fix.

16028 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16030 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16031 Default value is now t. Doc fix.
16033 * indent.c (Fvertical_motion): Compute and apply the overshoot
16034 logic when moving up, not only when moving down. Fix the
16035 confusing name and values of the it_overshoot_expected variable;
16036 logic changes accordingly. (Bug#9254) (Bug#9549)
16038 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16039 CHARPOS is covered by a display string which includes newlines.
16040 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16041 is covered by a display string with embedded newlines.
16043 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16045 * dbusbind.c (Fdbus_register_signal): Add match rule to
16046 Vdbus_registered_objects_table. (Bug#9581)
16047 (Fdbus_register_method, Vdbus_registered_objects_table):
16050 2011-09-24 Jim Meyering <meyering@redhat.com>
16052 do not ignore write error for any output size
16053 The previous change was incomplete.
16054 While it makes emacs --batch detect the vast majority of stdout
16055 write failures, errors were still ignored whenever the output size is
16056 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16057 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16058 && echo FAIL: ignored write error
16059 FAIL: ignored write error
16060 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16061 && echo FAIL: ignored write error
16062 FAIL: ignored write error
16063 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16065 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16067 * emacs.c (Fkill_emacs): In noninteractive mode exit
16068 non-successfully if a write error occurred on stdout. (Bug#9574)
16070 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16072 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16075 * dispextern.h (struct it): Update the comment documenting what
16078 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16080 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16081 a display string, extend search for cursor position to end of row.
16082 (find_row_edges): If the row ends in a newline from a display
16083 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16084 Handle the case of a display string with multiple newlines.
16085 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16086 non-empty line. Fixes confusing cursor motion with arrow keys at
16087 the beginning of a line that starts with whitespace.
16089 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16091 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16094 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16096 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16097 boolean (Bug#9154).
16099 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16101 * xdisp.c (display_line): Record maximum and minimum buffer
16102 positions even if no glyphs were produced (e.g., by a zero-width
16103 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16104 buffer positions that will be removed from the glyph row because
16106 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16107 column is beyond frame width: don't subtract 1 "pixel" when
16108 computing width of the stretch.
16109 (reseat_at_next_visible_line_start): Undo the change made on
16110 2011-09-17 that saved paragraph information and restored it after
16111 the call to `reseat'. (Bug#9545)
16113 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16115 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16116 and turn window cursor on if cleared (Bug#9415).
16118 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16120 * search.c (boyer_moore): Take unibyte characters from pattern
16121 literally. (Bug#9458)
16123 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16125 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16127 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16129 Fix minor problem found by static checking.

16131 initialized, to pacify gcc -Wuninitialized.
16133 * fileio.c: Report proper errno when syscall falls.
16134 (Finsert_file_contents): Save and restore errno,
16135 so that report_file_error outputs the correct diagnostic.
16136 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16138 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16140 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16142 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16144 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16145 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16147 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16149 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16150 about the current paragraph and restore it after the call to reseat.
16152 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16153 (bidi_find_paragraph_start): Search back for paragraph beginning
16154 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16155 (bidi_move_to_visually_next): Only trigger paragraph-related
16156 computations when the last character is a newline or at EOB, not
16157 just any NEUTRAL_B. (Bug#9470)
16159 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16160 truncated lines if point is covered by a display string. (Bug#9524)
16162 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16164 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16165 (cons_to_x_long): New function.
16166 (lisp_data_to_selection_data): Use it. Correct the test for
16167 short-versus-long data; it was negated. Break out of vector
16168 loop, for efficiency, when a long datum is discovered.
16170 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16172 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16174 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16176 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16177 GCC PR/17406) by declaring this function with external scope.
16179 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16181 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16182 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16184 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16186 * editfns.c (Fformat): Correctly handle text properties on "%%".

16194 * xdisp.c (get_next_display_element)
16195 (fill_composite_glyph_string): Add comments about special meaning
16196 of TAB characters in a composition.
16198 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16200 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16201 This occurs when processing a multibyte format.
16202 Problem reported by Wolfgang Jenker.
16204 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16206 * xdisp.c (try_cursor_movement): Only check for exact match if
16207 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16209 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16211 Remove unused external symbols.
16212 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16213 * xdisp.c (calc_pixel_width_or_height): Now static.
16214 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16215 * indent.c (check_display_width):
16216 * w32term.c: Fix comment to match code.
16217 * xterm.c, xterm.h (x_catching_errors): Remove.
16219 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16221 * xselect.c: Use signed conversions more consistently (Bug#9498).
16222 (selection_data_to_lisp_data): Assume incoming selection data are
16223 signed integers, not unsigned. This is to be consistent with
16224 outgoing selection data, which was modified to use signed integers
16225 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16226 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16227 expects long, not unsigned long.
16229 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16231 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16232 computation of loop end. Reported by Johan Bockgård
16235 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16237 * frame.c (Fother_visible_frames_p): Function deleted.
16239 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16241 * indent.c (compute_motion): Process display vector front to back
16242 rather than the other way around. (Bug#2496)
16244 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16246 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16248 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16250 * minibuf.c (Fread_from_minibuffer): Doc fix.
16252 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16254 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16255 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16257 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16259 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16260 value for non-existent files.
16262 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16264 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16265 set its "size" to -1. This will set the modtime_size field of
16266 the corresponding buffer to -1, which is what
16267 verify-visited-file-modtime expects for files that do not exist.
16270 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16272 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16274 * lisp.h: ... from here. push_key_description is no longer
16275 defined in keyboard.c, so its declaration should not be in
16276 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16277 logically belongs with push_key_description.
16279 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16281 * buffer.h: Include <sys/types.h> instead of <time.h>.
16282 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16283 Problem reported by Herbert J. Skuhra.
16285 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16287 * xml.c (parse_region): Make the parsing work for
16288 non-comment-starting XML files again (bug#9144).
16290 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16292 * image.c (gif_load): Fix calculation of bottom and right corner.
16295 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16297 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16298 redisplay in small windows.
16300 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16302 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16304 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16306 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16307 Operate on live windows only.
16309 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16311 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16313 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16315 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16316 only under bidi iteration.
16318 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16320 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16322 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16324 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16325 Without this fix, the command to link temacs failed due to an
16326 undefined symbol __builtin_isnan. This is because
16327 /usr/include/iso/math_c99.h #defines isnan(x) to
16328 __builtin_isnan(x), but the bundled gcc, which identifies itself
16329 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16331 * floatfns.c (isnan): #undef, and then #define to a clone of
16333 (Fisnan): Always define, since it's always available now.
16334 (syms_of_floatfns): Always define isnan at the Lisp level.
16336 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16338 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16340 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16342 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16343 The previous code assumed that file offsets (off_t values) fit in
16344 EMACS_INT variables, which is not true on typical 32-bit hosts.
16345 The code messed up by falsely reporting buffer overflow in cases
16346 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16347 when "big" contains more than 2**29 bytes, even though this
16348 inserts just one byte and does not overflow the buffer.
16349 (Finsert_file_contents): Store file offsets as off_t
16350 values, not as EMACS_INT values. Check for overflow when
16351 converting between EMACS_INT and off_t. When checking for
16352 buffer overflow or for overlap, take the offsets into account.
16353 Don't use EMACS_INT for small values where int suffices.
16354 When checking for overlap, fix a typo: ZV was used where
16355 ZV_BYTE was intended.
16356 (Fwrite_region): Don't assume off_t fits into 'long'.
16357 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16359 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16361 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16363 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16365 sprintf-related integer and memory overflow issues (Bug#9412).
16367 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16368 (esprintf, exprintf, evxprintf): New functions.
16369 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16370 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16371 (modify_event_symbol): Do not assume that the length of
16372 name_alist_or_stem is safe to alloca and fits in int.
16373 (Fexecute_extended_command): Likewise for function name and binding.
16374 (Frecursion_depth): Wrap around reliably on integer overflow.
16375 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16376 since some callers pass EMACS_INT values.
16377 (Fsingle_key_description): Don't crash if symbol name contains more
16378 than MAX_ALLOCA bytes.
16379 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16380 (get_minibuffer): Arg is now EMACS_INT, not int.
16381 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16382 (esprintf, exprintf, evxprintf): New decls.
16383 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16385 * dbusbind.c (signature_cat): New function.
16386 (xd_signature, Fdbus_register_signal):
16387 Do not overrun buffer; instead, report string overflow.
16389 * dispnew.c (add_window_display_history): Don't overrun buffer.
16390 Truncate instead; this is OK since it's just a log.
16392 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16393 even if the time zone offset is outlandishly large.
16394 Don't mishandle offset == INT_MIN.
16396 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16397 when creating daemon; the previous buffer-overflow check was incorrect.
16399 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16400 which has the guts of the old verror function.
16402 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16403 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16405 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16406 (font_unparse_xlfd): Don't blindly alloca long strings.
16407 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16408 fits in int, when using sprintf. Use single snprintf to count
16409 length of string rather than counting it via multiple sprintfs;
16410 that's simpler and more reliable.
16411 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16412 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16413 sprintf, in case result does not fit in int.
16415 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16416 (fontset_from_font): Print it.
16418 * frame.c (tty_frame_count): Now printmax_t, not int.
16419 (make_terminal_frame, set_term_frame_name): Print it.
16420 (x_report_frame_params): In X, window IDs are unsigned long,
16421 not signed long, so print them as unsigned.
16422 (validate_x_resource_name): Check for implausibly long names,
16423 and don't assume name length fits in 'int'.
16424 (x_get_resource_string): Don't blindly alloca invocation name;
16425 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16428 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16429 (xg_check_special_colors, xg_set_geometry):
16430 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16432 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16433 Use esprintf, not sprintf, in case result does not fit in int.
16435 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16436 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16437 it as a large positive number.
16438 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16439 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16441 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16442 in case result does not fit in int.
16444 * print.c (float_to_string): Detect width overflow more reliably.
16445 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16446 buffer overrun. Don't assume list length fits in 'int'. Treat
16447 print length of 0 as 0, not as infinity; to be consistent with other
16448 uses of print length in this function. Don't overflow print length
16449 index. Don't assume hash table size fits in 'long', or that
16450 vectorlike size fits in 'unsigned long'.
16452 * process.c (make_process): Use printmax_t, not int, to format
16453 process-name gensyms.
16455 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16457 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16458 to avoid potential buffer overrun.
16460 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16461 if X resource line is longer than 512 bytes.
16463 * xfns.c (x_window): Make sprintf buffer a bit bigger
16464 to avoid potential buffer overrun.
16466 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16468 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16470 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16472 Integer overflow fixes for scrolling, etc.
16473 Without these, Emacs silently mishandles large integers sometimes.
16474 For example, "C-u 4294967297 M-x recenter" was treated as if
16475 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16477 * xdisp.c (try_window_id): Check Emacs fixnum range before
16478 converting to 'int'.
16480 * window.c (window_scroll_line_based, Frecenter):
16481 Check that an Emacs fixnum is in range before assigning it to 'int'.
16482 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16483 values converted from Emacs fixnums.
16484 (Frecenter): Don't wrap around a line count if it is out of 'int'
16485 range; instead, treat it as an extreme value.
16486 (Fset_window_configuration, compare_window_configurations):
16487 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16489 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16490 that can exceed INT_MAX. Check that EMACS_INT value is in range
16491 before assigning it to the (possibly-narrower) index.
16492 (match_limit): Don't assume that a fixnum can fit in 'int'.
16494 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16497 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16498 (Fvertical_motion): Don't wrap around LINES values that don't fit
16499 in 'int'. Instead, treat them as extreme values. This is good
16500 enough for windows, which can't have more than INT_MAX lines anyway.
16502 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16504 * Require libxml/parser.h to avoid compilation warning.
16506 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16508 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16509 since this reportedly can destroy thread storage.
16511 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16513 * syntax.c (find_defun_start): Update all cache variables if
16514 exiting early (Bug#9401).
16516 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16518 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16520 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16521 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16522 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16524 * term.c (tty_append_glyph): New function.
16525 (produce_stretch_glyph): Static function and its prototype deleted.
16527 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16530 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16532 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16533 when checking :margin (Bug#9390).
16534 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16535 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16536 so that the name doesn't mislead. All uses changed.
16538 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16540 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16543 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16545 * xdisp.c (move_it_to): Don't bail out early when reaching
16546 position beyond to_charpos, if we are scanning backwards.
16547 (move_it_vertically_backward): When DY == 0, make sure we get to
16548 the first character in the line after the newline.
16550 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16552 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16553 (ccl_driver): Do not generate an out-of-range pointer.
16554 (Fccl_execute_on_string): Remove unnecessary check for
16555 integer overflow, noted by Stefan Monnier in
16556 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16557 Remove a FIXME that didn't need fixing.
16558 Simplify the newly-introduced buffer reallocation code.
16560 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16562 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16564 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16566 Integer and memory overflow issues (Bug#9196).
16568 * doc.c (get_doc_string): Rework so that
16569 get_doc_string_buffer_size is the actual buffer size, rather than
16570 being 1 less than the actual buffer size; this makes xpalloc more
16573 * image.c (x_allocate_bitmap_record, cache_image):
16574 * xselect.c (Fx_register_dnd_atom):
16575 Simplify previous changes by using xpalloc.
16577 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16578 since either will do and ptrdiff_t is convenient with xpalloc.
16580 * charset.c (charset_table_size)
16581 (struct charset_sort_data.priority): Now ptrdiff_t.
16582 (charset_compare): Don't overflow if priorities differ greatly.
16583 (Fsort_charsets): Don't assume list length fits in int.
16584 Check for size-calculation overflow when allocating sort data.
16585 (syms_of_charset): Allocate an initial charset table that is
16586 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16588 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16590 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16591 The actual value is always <= INT_MAX, and leaving it unsigned made
16592 overflow checking harder.
16594 * dispextern.h (struct glyph_matrix.rows_allocated)
16595 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16596 with xpalloc. The values are still always <= INT_MAX.
16598 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16600 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16601 (SAFE_NALLOCA): New macro.
16603 * region-cache.c (struct boundary.pos, find_cache_boundary)
16604 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16605 (set_cache_region, invalidate_region_cache)
16606 (revalidate_region_cache, know_region_cache, region_cache_forward)
16607 (region_cache_backward, pp_cache):
16608 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16609 so that ptrdiff_t * can be passed to xpalloc.
16610 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16611 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16612 (pp_cache): Don't assume cache_len fits in int.
16613 * region-cache.h: Adjust extern decls to match.
16615 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16616 EMACS_INT, since either will do, for xpalloc.
16618 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16619 (xnmalloc, xnrealloc, xpalloc): New functions.
16621 * bidi.c (bidi_shelve_header_size): New constant.
16622 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16623 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16625 * bidi.c (bidi_cache_shrink):
16626 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16628 Don't update size of array until after memory allocation succeeds,
16629 because xmalloc/xrealloc may not return.
16630 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16631 now that we have proper integer overflow checking.
16632 (record_overlay_string, overlay_strings): Catch overflows when
16633 calculating size of overlay_str_buf.
16635 * callproc.c (Fcall_process): Check for size overflow when
16636 calculating size of args2.
16637 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16638 Normally we prefer signed values, but sticking with ptrdiff_t would
16639 require adding more-complicated checks.
16641 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16642 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16643 Redo buffer-overflow calculations to avoid integer overflow.
16644 Add a FIXME comment where memory seems to be over-allocated.
16646 * character.c (Fstring): Check for size-calculation overflow.
16648 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16649 unnecessary integer overflow. Check for size overflow.
16650 (encode_coding_object): Don't update size until xmalloc succeeds.
16652 * composite.c (get_composition_id): Check for overflow in glyph
16653 length calculations.
16655 Integer and memory overflow fixes for display code.
16656 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16657 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16658 (scrolling_window): Check for overflow in size calculations.

16670 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16671 (get_doc_string): Check for size calculation overflow.
16672 Don't update size until allocation succeeds.
16673 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16674 EMACS_INT, where ptrdiff_t will do.
16675 (Fsubstitute_command_keys): Check for string overflow.
16677 * editfns.c (set_time_zone_rule): Don't assume environment length
16679 (message_length): Now ptrdiff_t, not int.
16680 (Fmessage_box): Don't update size until allocation succeeds.
16681 Don't assume message length fits in int.
16682 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16684 * emacs.c (main): Do not reallocate argv, since there is a null at
16685 the end that can be overwritten, and this way there's no need to
16686 worry about size-calculation overflow.
16687 (sort_args): Check for size-calculation overflow.
16689 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16691 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16693 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16694 (x_set_scroll_bar_width, x_figure_window_size):
16695 Check for integer overflow.
16696 (x_set_alpha): Do not assume XINT fits in int.
16698 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16699 This is for the members text_lines, text_cols, total_lines, total_cols,
16700 where the system imposes an 'int' limit.
16702 * fringe.c (Fdefine_fringe_bitmap):
16703 Don't update size until alloc works.
16705 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16706 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16708 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16709 Check for size-calculation overflow.
16710 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16711 do, as we prefer signed integers.
16712 (id_to_widget.max_size, id_to_widget.used)
16713 (xg_store_widget_in_map, xg_remove_widget_from_map)
16714 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16715 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16716 Use and return ptrdiff_t, not int.
16717 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16718 * gtkutil.h: Change prototypes to match the above.
16720 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16721 are duplicate now that they've been promoted to lisp.h.
16722 (x_allocate_bitmap_record, x_alloc_image_color)
16723 (make_image_cache, cache_image, xpm_load):
16724 Don't update size until alloc is done.
16725 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
16727 Check for size calculation overflow.
16728 (ct_colors_allocated_max): New constant.
16729 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
16732 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
16733 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
16734 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
16735 Use ptrdiff_t, not int, to count maps.
16736 (read_char_minibuf_menu_prompt): Check for overflow in size
16737 calculations. Don't update size until allocation succeeds.
16738 Redo calculations to avoid overflow.
16739 * keyboard.h: Change prototypes to match the above.
16741 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
16743 (current_minor_maps): Check for size calculation overflow.
16744 * keymap.h: Change prototypes to match the above.
16746 * lread.c (read1, init_obarray): Don't update size until alloc done.
16748 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

16751 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
16752 Now ptrdiff_t, not int.
16753 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

16765 (Fset_match_data): Don't assume list lengths fit in 'int'.
16767 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16768 for command line length. Do not attempt to address one before the
16769 beginning of an array, as that's not portable.
16771 * term.c (max_frame_lines): Remove; unused.
16772 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
16774 (encode_terminal_code, calculate_costs): Check for size
16775 calculation overflow.

16778 done. Redo calculations to avoid overflow.
16779 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
16781 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
16782 subtracting pointers.
16783 (gobble_line): Check for overflow more carefully. Don't update size
16786 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

16797 Use ptrdiff_t, not int, for sizes.
16798 (Finternal_make_lisp_face, cache_face):
16799 Check for size calculation overflow.
16800 (cache_face): Treat size calculation overflows as if they were
16801 memory exhaustion (the usual treatment), rather than aborting.
16803 * xfns.c (x_encode_text, x_set_name_internal)
16804 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16805 sizes, since they can exceed INT_MAX in size. Check for size
16806 calculation overflow.
16808 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16809 (xg_select): Check for size calculation overflow.
16810 Don't update size until alloc done.
16812 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16813 as sprintf is limited to int lengths.
16815 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16816 (X_LONG_MIN): New macros.
16817 Use them to make the following changes clearer.
16818 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16819 This change doesn't affect the value now, but it may help remind
16820 future maintainers not to raise the value too much later.
16821 (SELECTION_QUANTUM): Remove, replacing with ...
16822 (selection_quantum): ... new function, which avoids overflow.
16824 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16825 assumption that selection length fits in 'int'.
16826 (x_reply_selection_request, x_handle_selection_request)
16827 (x_get_window_property, receive_incremental_selection)
16828 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
16829 (lisp_data_to_selection_data, clean_local_selection_data):

16831 (x_reply_selection_request, x_get_window_property)
16832 (receive_incremental_selection, x_property_data_to_lisp):
16833 Redo calculations to avoid overflow.
16834 (x_reply_selection_request): When sending hint, ceiling it at
16835 X_LONG_MAX rather than relying on wraparound overflow to send
16837 (x_get_window_property, receive_incremental_selection)
16838 (lisp_data_to_selection_data, x_property_data_to_lisp):
16839 Check for size-calculation overflow.
16840 (x_get_window_property, receive_incremental_selection)
16841 (lisp_data_to_selection_data, Fx_register_dnd_atom):
16842 Don't store size until memory allocation succeeds.
16843 (x_get_window_property): Plug memory leak on memory exhaustion.
16844 Don't double-block input; malloc is safe here. Don't assume 2**34
16845 - 4 fits in unsigned long. Add an xassert to check
16846 XGetWindowProperty overflow. Be more careful about overflow
16847 calculations, and distinguish size from memory overflow better.
16848 (receive_incremental_selection): When tracing, don't assume
16849 unsigned int is less than INT_MAX.
16850 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16851 harmful) conversions of unsigned short to int.
16852 (lisp_data_to_selection_data): Don't assume that integers
16853 in the range -65535 through -1 fit in an X unsigned short.
16854 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16855 result parameters unless successful. Rely on cons_to_unsigned
16856 to report problems with elements; the old code wasn't right anyway.
16857 (x_check_property_data): Check for int overflow; we cannot use
16858 a wider type due to X limits.
16859 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
16861 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

16891 * lisp.h (hash_lookup, hash_put):
16892 * minibuf.c (Ftest_completion):
16893 Use ptrdiff_t for hash table indexes, not int (which is too
16894 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16895 32-bit --with-wide-int hosts).
16897 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16898 Add a FIXME comment about memory leaks.
16899 (syms_of_charset): Don't assume xmalloc returns.
16901 Don't assume that stated character widths fit in int.
16902 * character.c (Fchar_width, c_string_width, lisp_string_width):
16903 * character.h (CHAR_WIDTH):
16904 * indent.c (MULTIBYTE_BYTES_WIDTH):
16905 Use sanitize_char_width to avoid undefined and/or bad behavior
16906 with outlandish widths.
16907 * character.h (sanitize_tab_width): Rename from sanitize_width,
16908 now that we have two such functions. All uses changed.
16909 (sanitize_char_width): New inline function.
16911 Don't assume that tab-width fits in int.
16912 * character.h (sanitize_width): New inline function.
16913 (SANE_TAB_WIDTH): New macro.
16914 (ASCII_CHAR_WIDTH): Use it.
16915 * indent.c (sane_tab_width): Remove. All uses replaced by

16919 * fileio.c: Integer overflow issues with file modes.
16920 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
16922 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
16923 Remove unreachable code.
16924 (read_hex, load_charset_map_from_file): Check for integer overflow.
16926 * xterm.c: Don't go over XClientMessageEvent limit.
16927 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16928 (x_send_scroll_bar_event): Likewise. Check that the size does not
16929 exceed limits imposed by XClientMessageEvent, as well as the usual
16930 ptrdiff_t and size_t limits.
16932 * keyboard.c: Overflow, signedness and related fixes.
16933 (make_lispy_movement): Use same integer type in forward decl
16934 that is used in the definition.
16935 (read_key_sequence, keyremap_step):
16936 Change bufsize argument back to int, undoing my 2011-03-30 change.
16937 We prefer signed types, and int is wide enough here.
16938 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16939 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16940 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16941 length, not size_t. Use ptrdiff_t for index, not int.
16942 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16943 possibility of integer overflow.
16945 Overflow, signedness and related fixes for images.
16947 * dispextern.h (struct it.stack[0].u.image.image_id)
16948 (struct_it.image_id, struct image.id, struct image_cache.size)

16955 * xdisp.c (calc_pixel_width_or_height):
16956 * xfns.c (image_cache_refcount):
16957 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
16958 on typical 64-bit hosts.

16964 when the callers expect that.
16965 (image_ascent): Redo ascent calculation to avoid int overflow.
16966 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
16967 (lookup_image): Remove unnecessary tests.
16968 (xbm_image_p): Locals are now of int, not EMACS_INT,
16969 since parse_image_check makes sure they fit into int.
16970 (png_load, gif_load, svg_load_image):
16971 Prefer int to unsigned where either will do.
16972 (tiff_handler): New function, combining the cores of the
16973 old tiff_error_handler and tiff_warning_handler.
16974 This function is rewritten to use vsnprintf and thereby avoid
16975 stack buffer overflows. It uses only the features of vsnprintf
16976 that are common to both POSIX and native Microsoft.
16977 (tiff_error_handler, tiff_warning_handler): Use it.
16978 (tiff_load, gif_load, imagemagick_load_image):
16979 Don't assume :index value fits in 'int'.
16980 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16981 (imagemagick_load_image): Check that crop parameters fit into
16982 the integer types that MagickCropImage accepts. Don't assume
16983 Vimagemagick_render_type has a nonnegative value. Don't assume
16984 size_t fits in 'long'.
16985 (gs_load): Use printmax_t to print the widest integers possible.
16986 Check for integer overflow when computing image height and width.

16995 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
16996 the display spec is of the form `(space ...)'.
16997 (handle_display_spec): Return the value returned by
16998 handle_single_display_spec, not just 1 or zero.
16999 (handle_single_display_spec): If the display spec is of the form
17000 `(space ...)', and specifies display in the text area, return 2
17002 (try_cursor_movement): Check for the need to scroll more
17003 accurately, and prefer exact match for point under bidi.
17004 Don't advance `row' beyond the last row of the window.
17006 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
17007 into disp_prop; all users changed.
17009 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
17010 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
17011 for the text covered by the display property.

17021 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
17022 buffers, return left-to-right.
17023 (set_cursor_from_row): Consider candidate row a win if its glyph
17024 represents a newline and point is on that newline. Fixes cursor
17025 positioning on the newline at EOL of R2L text within L2R
17026 paragraph, and vice versa.
17027 (try_cursor_movement): Check continued rows, in addition to
17028 continuation rows. Fixes unwarranted scroll when point enters a
17029 continued line of R2L text within an L2R paragraph, or vice versa.
17030 (cursor_row_p): Consider the case of point being equal to
17031 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
17032 from the end of a short line to the beginning of a continued line
17033 of R2L text within L2R paragraph.
17034 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
17035 composed characters.
17037 * bidi.c (bidi_check_type): Use xassert.

17050 2011-08-22 Kenichi Handa <handa@m17n.org>
17052 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
17053 extra slot even if the purpose is char-code-property-table.
17055 2011-08-23 Eli Zaretskii <eliz@gnu.org>
17057 * xdisp.c (redisplay_window): When computing centering_position,
17058 account for the height of the header line. (Bug#8874)
17060 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17061 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17062 candidate is selected by the mouse, and that candidate has a
17063 composed character under the mouse.
17065 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17066 coordinates reported by pos-visible-in-window-p for a composed
17067 character in column zero.
17069 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
17071 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
17073 2011-08-22 Eli Zaretskii <eliz@gnu.org>
17075 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
17076 consider it a hit if to_charpos is anywhere in the range of the
17077 composed buffer positions.
17079 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17081 * image.c (gif_load): Don't assume that each subimage has the same
17082 dimensions as the base image. Handle disposal method that is
17083 "undefined" by the gif spec (Bug#9335).
17085 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17087 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17090 2011-08-19 Eli Zaretskii <eliz@gnu.org>
17092 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
17093 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17094 from an Org mode buffer to a Speedbar frame.
17096 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17097 a composition, take its buffer position from IT->cmp_it.charpos.
17098 Fixes cursor positioning at the beginning of a line that begins
17099 with a composed character.
17101 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17103 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17104 character bidirectional type, use STRONG_L instead. Fixes crashes
17105 in a buffer produced by `describe-categories'.
17107 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17108 members before the level stack, so they would be saved and
17109 restored when copying iterator state. Fixes incorrect reordering
17110 around TABs covered by display properties.
17112 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17114 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

17119 (internal_condition_case_2, internal_condition_case_n):
17120 Remove unnecessary aborts (Bug#9081).
17122 2011-08-17 Eli Zaretskii <eliz@gnu.org>
17124 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
17125 has no `load' handler, try opening the file locally. (Bug#9311)
17127 2011-08-16 Ken Brown <kbrown@cornell.edu>
17129 * gmalloc.c: Expand comment.
17131 2011-08-16 Eli Zaretskii <eliz@gnu.org>
17133 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
17134 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.

17179 * process.c (create_process): Call setup_process_coding_systems
17180 after the pid of the process is set to -1 (Bug#8162).
17182 2011-08-14 Eli Zaretskii <eliz@gnu.org>
17184 * xdisp.c (move_it_in_display_line_to): Don't invoke
17185 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17186 ppos_it. Fixes vertical cursor motion when line beginning is
17187 covered by an image. (Bug#9296)
17189 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17191 * nsterm.h (ns_run_ascript): Declare.

17195 (ns_run_ascript): New function.
17196 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17197 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17198 the event loop. Get status from as_status (Bug#7276).
17200 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17201 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17202 the event loop (Bug#7276).
17204 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

17227 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
17228 (Fnetwork_interface_list): Allocate in increments of bytes instead
17229 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17230 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17232 (struct ifflag_def): notrailers is smart on OSX.
17233 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17234 Get hardware address with getifaddrs if available.
17236 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17238 * xdisp.c (iterate_out_of_display_property): xassert that
17239 IT->position is set to within IT->object's boundaries. Break from
17240 the loop as soon as EOB is reached; avoids infloops in redisplay
17241 when IT->position is set up wrongly due to some bug.
17242 Set IT->current to match the bidi iterator unconditionally.
17243 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17244 entry. Force push_it to save on the stack the current
17245 buffer/string position, to be restored by pop_it. Fix flags in
17246 the iterator structure wrt the object coming from a display
17247 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17248 properties. (Bug#9284)
17250 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17252 * fontset.c (fontset_get_font_group): Add proper type checks.

17265 no-display-properties-and-no-overlays under bidi display.
17266 Set disp_pos in the bidi iterator to avoid searches for display
17267 properties and overlays.
17269 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
17271 * editfns.c (Fset_time_zone_rule): Document relationship with the

17277 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
17279 * composite.c (autocmp_chars): Don't reset point. That is done by
17280 restore_point_unwind (Bug#5984).
17282 2011-08-07 Juri Linkov <juri@jurta.org>
17284 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17285 to show the arg `TIME' instead of `TIMEVAL'.
17287 2011-08-06 Eli Zaretskii <eliz@gnu.org>
17289 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17290 display property strides EOL and includes a newline, as in
17291 longlines-mode. (Bug#9254)
17292 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17293 word-wrap under bidirectional display. (Bug#9224)
17295 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17296 is non-zero, even if the data buffer is NULL. Fixes a crash in
17297 vertical-motion with longlines-mode. (Bug#9254)
17299 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17301 * bidi.c <bidi_cache_total_alloc>: Now static.
17302 (bidi_initialize): Initialize bidi_cache_total_alloc.
17304 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17307 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17308 amount allocated this far in `bidi_cache_total_alloc'.
17309 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17310 non-zero, only free the data buffer without restoring the cache
17311 contents. All callers changed.
17313 * dispextern.h (bidi_unshelve_cache): Update prototype.
17315 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17316 (move_it_in_display_line, move_it_to)
17317 (move_it_vertically_backward, move_it_by_lines): Replace the call
17318 to xfree to an equivalent call to bidi_unshelve_cache.
17319 (move_it_in_display_line_to): Fix logic of returning
17320 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17322 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17324 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
17325 came from a string character with a `cursor' property. (Bug#9229)
17327 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17329 * Makefile.in (LIB_PTHREAD): New variable.
17330 (LIBES): Add LIB_PTHREAD (Bug#9216).
17332 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:

17339 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17341 * xterm.c (x_find_topmost_parent): New function.
17342 (x_set_frame_alpha): Find topmost parent window with
17343 x_find_topmost_parent and set the property there also (bug#9181).
17344 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
17346 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
17348 * callproc.c (Fcall_process): Avoid vfork clobbering
17349 the local vars buffer, coding_systems, current_dir.
17351 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
17353 * keymap.c (Fmake_composed_keymap): Move to subr.el.
17355 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
17357 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
17358 so that it is not optimized away.
17360 * xdisp.c (compute_display_string_pos): Remove unused local.
17362 2011-08-02 Eli Zaretskii <eliz@gnu.org>
17364 Fix slow cursor motion and scrolling in large buffers with
17365 selective display, like Org Mode buffers. (Bug#9218)
17367 * dispextern.h (struct bidi_it): New member disp_prop_p.
17369 * xdisp.c: Remove one-slot cache of display string positions.
17370 (compute_display_string_pos): Accept an additional argument
17371 DISP_PROP_P; callers changed. Scan at most 5K characters forward
17372 for a display string or property. If found, set DISP_PROP_P
17375 * bidi.c (bidi_fetch_char): Accept an additional argument
17376 DISP_PROP_P, and pass it to compute_display_string_pos.
17377 Only handle text covered by a display string if DISP_PROP_P is returned
17378 non-zero. All callers of bidi_fetch_char changed.
17380 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17382 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17384 2010-12-03 Don March <don@ohspite.net>
17386 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17387 last character M-[char] is translated to ESC [char] (bug#7541).
17389 2011-08-02 Kenichi Handa <handa@m17n.org>
17391 * lisp.h (uniprop_table): Extern it.
17393 * chartab.c (uniprop_table): Make it non-static.
17395 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17397 * xdisp.c (forward_to_next_line_start): Accept additional argument
17398 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17400 (reseat_at_next_visible_line_start): Use the bidi iterator state
17401 returned by forward_to_next_line_start to restore the state of
17402 it->bidi_it after backing up to previous newline. (Bug#9212)
17404 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17406 * regex.c (re_comp): Protoize.
17407 (re_exec): Fix return type.
17408 (regexec): Fix type of `ret'. (Bug#9203)
17410 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17412 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17413 This is needed if max-image-size is a floating-point number.
17415 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17417 * print.c (print_object): Print empty symbol as ##.
17419 * lread.c (read1): Read ## as empty symbol.
17421 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17423 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17424 setting frame foreground color (Bug#9175).
17425 (x_set_background_color): Likewise.
17427 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17428 contents (Bug#9176).
17429 (EmacsTooltip -init): Remove bezels and add shadows to
17432 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17433 or scroll bar (Bug#8470).
17435 * nsfont.m (nsfont_open): Remove assignment to voffset and
17436 unnecessary vars hshink, expand, hd, full_height, min_height.
17437 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17439 * nsterm.h (nsfont_info): Remove voffset field.
17441 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17443 Implement strike-through and overline on NextStep (Bug#8863).
17445 * nsfont.m (nsfont_open): Use underline position provided by font,
17446 instead of hard-coded value of 2.
17447 (nsfont_draw): Call ns_draw_text_decoration instead.
17449 * nsterm.h: Add declaration for ns_draw_text_decoration.
17451 * nsterm.m (ns_draw_text_decoration): New function for drawing
17452 underline, overline, and strike-through.
17453 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17454 ns_draw_text_decoration. Change treatment of cursor drawing to
17455 accommodate underlining, etc.
17457 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17459 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17462 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17464 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17465 Without this fix, if a signal arrives just after memory fills up,
17466 'malloc' might be invoked reentrantly.
17468 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17469 In other words, assume that every image size is allowed, on non-X
17470 hosts. This assumption is probably wrong, but it lets Emacs compile.
17472 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17474 * regex.c (re_iswctype): Convert return values to boolean.
17476 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17478 * xdisp.c (compute_display_string_pos): Don't use cached display
17479 string position if the buffer had its restriction changed.
17482 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17484 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17486 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17488 Integer signedness and overflow and related fixes. (Bug#9079)
17490 * bidi.c: Integer size and overflow fixes.
17491 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17492 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17493 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17494 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17495 (bidi_find_other_level_edge):
17496 Use ptrdiff_t instead of EMACS_INT where either will do.
17497 This works better on 32-bit hosts configured --with-wide-int.
17498 (bidi_cache_ensure_space): Check for size-calculation overflow.
17499 Use % rather than repeated addition, for better worst-case speed.
17500 Don't set bidi_cache_size until after xrealloc returns, because it
17502 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17503 (bidi_cache_ensure_space): Also check that the bidi cache size
17504 does not exceed that of the largest Lisp string or buffer. See Eli
17505 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17507 * alloc.c (__malloc_size_t): Remove.
17508 All uses replaced by size_t. See Andreas Schwab's note
17509 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17511 * image.c: Improve checking for integer overflow.
17512 (check_image_size): Assume that f is nonnull, since
17513 it is always nonnull in practice. This is one less thing to
17514 worry about when checking for integer overflow later.
17515 (x_check_image_size): New function, which checks for integer
17516 overflow issues inside X.
17517 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17518 This removes the need for a memory_full check.
17519 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17520 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17521 (xbm_read_bitmap_data): Change locals back to 'int', since
17522 their values must fit in 'int'.
17523 (xpm_load_image, png_load, tiff_load):
17524 Invoke x_create_x_image_and_pixmap earlier,
17525 to avoid much needless work if the image is too large.
17526 (tiff_load): Treat overly large images as if
17527 x_create_x_image_and_pixmap failed, not as malloc failures.
17528 (gs_load): Use x_check_image_size.
17530 * gtkutil.c: Omit integer casts.
17531 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17532 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17534 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17536 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17537 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17538 would wrongly return t on a 64-bit host.
17540 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17541 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17542 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17543 and therefore cause GCC to emit a bogus diagnostic in some cases.
17545 * image.c: Integer signedness and overflow and related fixes.
17546 This is not an exhaustive set of fixes, but it's time to
17547 record what I've got.
17548 (lookup_pixel_color, check_image_size): Remove redundant decls.
17549 (check_image_size): Don't assume that arbitrary EMACS_INT values
17550 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17551 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17552 (tiff_load, imagemagick_load_image):
17553 Check for overflow in size calculations.
17554 (x_create_x_image_and_pixmap): Remove unnecessary test for
17555 xmalloc returning NULL; that can't happen.
17556 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17557 (xpm_color_bucket): Use better integer hashing function.
17558 (xpm_cache_color): Don't possibly over-allocate memory.
17559 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17560 (gif_memory_source):
17561 Use ptrdiff_t, not int or size_t, to record sizes.
17562 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17563 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17564 either works, as we prefer signed integers.
17565 (tiff_read_from_memory, tiff_write_from_memory):
17566 Return tsize_t, not size_t, since that's what the TIFF API wants.
17567 (tiff_read_from_memory): Don't fail simply because the read would
17568 go past EOF; instead, return a short read.
17569 (tiff_load): Omit no-longer-needed casts.
17570 (Fimagemagick_types): Don't assume size fits into 'int'.
17572 Improve hashing quality when configured --with-wide-int.
17573 * fns.c (hash_string): New function, taken from sxhash_string.
17574 Do not discard information about ASCII character case; this
17575 discarding is no longer needed.
17576 (sxhash-string): Use it. Change sig to match it. Caller changed.
17577 * lisp.h: Declare it.
17578 * lread.c (hash_string): Remove, since we now use fns.c's version.
17579 The fns.c version returns a wider integer if --with-wide-int is
17580 specified, so this should help the quality of the hashing a bit.
17582 * emacs.c: Integer overflow minor fix.
17583 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17584 Define only if GNU_LINUX.
17585 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17587 * dispnew.c: Integer signedness and overflow fixes.
17588 Remove unnecessary forward decls, that were a maintenance hassle.
17589 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17591 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17592 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17593 (prepare_desired_row, line_draw_cost):
17594 Use int, not unsigned, where either works.
17595 (save_current_matrix, restore_current_matrix):
17596 Use ptrdiff_t, not size_t, where either works.
17597 (init_display): Check for overflow more accurately, and without
17598 relying on undefined behavior.
17600 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17601 Remove, replacing with the new symbols in lisp.h. All uses changed.
17602 * fileio.c (make_temp_name):
17603 * filelock.c (lock_file_1, lock_file):
17604 * xdisp.c (message_dolog):
17605 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17606 Use pMd etc. instead.
17607 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17608 replacing the pWIDE etc. symbols removed from editfns.c.
17610 * keyboard.h (num_input_events): Now uintmax_t.
17611 This is (very slightly) less likely to mess up due to wraparound.
17614 * buffer.c: Integer signedness fixes.
17615 (alloc_buffer_text, enlarge_buffer_text):
17616 Use ptrdiff_t rather than size_t when either will do, as we prefer
17619 * alloc.c: Integer signedness and overflow fixes.
17620 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17621 (__malloc_size_t): Default to size_t, not to int.
17622 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17623 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17624 Prefer ptrdiff_t to size_t when either would do, as we prefer
17626 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17627 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17628 Now const. Initialize with values that are in range even if char
17630 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17631 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17632 These functions do the right thing with sizes > 2**32.
17633 (check_depth): Now ptrdiff_t, not int.
17634 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17635 Adjust to new way of storing sizes. Check for size overflow bugs
17637 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17638 slightly wrong anyway, as it missed one instance of
17639 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17640 (refill_memory_reserve): Omit needless cast to size_t.
17641 (mark_object_loop_halt): Mark as externally visible.
17643 * xselect.c: Integer signedness and overflow fixes.
17644 (Fx_register_dnd_atom, x_handle_dnd_message):
17645 Use ptrdiff_t, not size_t, since we prefer signed.
17646 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17647 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17648 x_dnd_atoms_size and x_dnd_atoms_length.
17650 * doprnt.c: Prefer signed to unsigned when either works.
17652 * doprnt.c (doprnt):
17654 * xdisp.c (vmessage):
17655 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17656 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17657 prefer signed arithmetic to avoid comparison confusion.
17658 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17659 but is a bit tricky.
17661 Assume freestanding C89 headers, string.h, stdlib.h.
17662 * data.c, doprnt.c, floatfns.c, print.c:
17663 Include float.h unconditionally.
17664 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17665 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17666 * regex.c: Likewise for stddef.h, string.h.
17667 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17668 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17669 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17670 (STDC_HEADERS): Remove obsolete defines.
17671 * sysdep.c: Include limits.h unconditionally.
17673 Assume support for memcmp, memcpy, memmove, memset.
17674 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17675 * regex.c (memcmp, memcpy):
17676 Remove; we assume C89 now.
17678 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17679 (__malloc_safe_bcopy): Remove; no longer needed.
17681 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17682 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17683 well either way, and we prefer signed to unsigned.
17685 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17687 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17688 closes the connection while we're reading (bug#9182).
17690 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17692 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17693 are specified (Bug#9168).
17695 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17697 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17698 Found by GCC static checking and --with-wide-int on a 32-bit host.
17700 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17702 * xdisp.c (compute_display_string_pos): Fix logic of caching
17703 previous display string position. Initialize cached_prev_pos to
17704 -1. Fixes slow-down at the beginning of a buffer.
17706 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17708 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17709 for attrs[LFACE_FONTSET_INDEX].
17711 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17713 * xml.c (parse_region): Remove unused local
17714 that was recently introduced.
17716 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17718 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17719 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17721 * xdisp.c (move_it_in_display_line_to): Record the best matching
17722 position for TO_CHARPOS while scanning the line, and restore it on
17723 exit if none of the characters scanned was an exact match.
17724 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17725 when exact match is impossible due to invisible text, and the
17726 lines are truncated.
17728 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17730 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17733 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17735 Fix a significant slow-down of cursor motion with C-n, C-p,
17736 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17737 auto-repeat under bidi redisplay in fontified buffers.
17738 * xdisp.c (compute_stop_pos_backwards): New function.
17739 (next_element_from_buffer): Call compute_stop_pos_backwards to
17740 find a suitable prev_stop when we find ourselves before
17742 (reseat): Don't look for prev_stop, as that could mean a very long
17744 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17745 <cached_disp_overlay_modiff>: Cache for last found display string
17747 (compute_display_string_pos): Return the cached position if asked
17748 about the same buffer in the same area of character positions, and
17749 the buffer wasn't changed since the time the display string
17750 position was cached.
17752 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17754 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17755 is an integer, which is important for empty lines. (Bug#9149)
17757 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17759 * frame.c (Fmodify_frame_parameters): In tty case, update the
17760 default face if necessary (Bug#4238).
17762 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17764 * editfns.c (Fstring_to_char): No need to explain what a character
17765 is in the docstring (Bug#6576).
17767 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17769 * xml.c (parse_region): Make sure we always return a tree.
17771 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17773 * xml.c (parse_region): If a document contains only comments,
17776 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17778 * xml.c (make_dom): Return comments, too.
17780 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17783 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17784 and the surrounding thread.
17785 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17786 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17787 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17789 * s/openbsd.h (BROKEN_SIGIO): Define.
17790 * unexelf.c (unexec) [__OpenBSD__]:
17791 Don't update the .mdebug section of the Alpha COFF symbol table.
17793 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17795 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17798 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17800 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17801 This fixes some race conditions on the permissions of any newly
17804 * alloc.c (valid_pointer_p): Use pipe, not open.
17805 This fixes some permissions issues when debugging.
17807 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17808 If fchown fails to set both uid and gid, try to set just gid,
17809 as that is sometimes allowed. Adjust the file's mode to eliminate
17810 setuid or setgid bits that are inappropriate if fchown fails.
17812 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17814 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ

17820 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17822 * lread.c (read_integer): Unread even EOF character.
17823 (read1): Likewise. Properly record start position of symbol.

17826 symbol character follows.
17828 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17830 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17831 This works around a problem with the previous change to Fcopy_file.
17832 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17833 and without this change, GCC might complain about discarding
17834 fchown's return value.
17836 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17838 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17840 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17842 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17844 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17846 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17847 it's used from the C level.
17849 * process.c: Use the same condition for POLL_FOR_INPUT in both
17850 keyboard.c and process.c (bug#1858).
17852 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17854 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17855 (Fgnutls_boot): Use it.
17857 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17859 * doc.c (Fsubstitute_command_keys): Revert last change.
17861 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17863 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17864 quotes the next character, and doesn't affect other longer
17865 sequences (bug#8935).
17867 * lread.c (syms_of_lread): Clarify that is isn't only
17868 `eval-buffer' and `eval-defun' that's affected by
17869 `lexical-binding' (bug#8460).

17874 bidi redisplay when a line includes both an image and is truncated.
17876 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17878 Fix minor problems found by static checking.
17879 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17880 (elsz): Now a signed constant, not a size_t var. We prefer signed
17881 types to unsigned, to avoid integer comparison confusion. Without
17882 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17883 "cannot optimize loop, the loop counter may overflow", a symptom
17885 * indent.c (Fvertical_motion): Mark locals as initialized.
17886 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17888 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17890 * search.c (Fre_search_backward): Mention `case-fold-search' in
17891 all the re_search_* functions (bug#8138).

17914 (display_string): If we need to ignore text properties of
17915 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17916 original value of -1 will not work with bidi.)
17917 (compute_display_string_pos): First arg is now struct
17918 `text_pos *'; all callers changed. Support display properties on
17920 (compute_display_string_end): Support display properties on Lisp
17922 (init_iterator, reseat_1, reseat_to_string): Initialize the
17923 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17924 when iterating on a string not from display properties).
17925 (compute_display_string_pos, compute_display_string_end):
17926 Fix calculation of the object to scan. Fixes an error when using
17928 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17929 base_level_stop; instead, set base_level_stop to BEGV.
17930 Fixes crashes in vertical-motion.
17931 (next_element_from_buffer): Improve commentary for when
17932 the iterator is before prev_stop.
17933 (init_iterator): Initialize bidi_p from the default value of
17934 bidi-display-reordering, not from buffer-local value. Use the
17935 buffer-local value only if initializing for buffer iteration.

17945 (init_iterator): Don't initialize it->bidi_p for strings
17947 (reseat_to_string): Initialize it->bidi_p for strings here.

17956 parts of next_element_from_buffer, next_element_from_string, and
17957 next_element_from_c_string.
17958 (tool_bar_lines_needed, redisplay_tool_bar)
17959 (display_menu_bar): Force left-to-right direction. Add a FIXME
17960 comment for making that be controlled by a user option.

17970 iterator for displaying display or overlay strings.
17971 (forward_to_next_line_start): Don't use the shortcut if
17973 (back_to_previous_visible_line_start): If handle_display_prop
17974 pushed the iterator stack, restore the internal state of the bidi
17975 iterator by calling bidi_pop_it same number of times.
17976 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17977 and we are bidi-iterating, don't decrement the iterator position;
17978 instead, set the first_elt flag in the bidi iterator, to produce
17980 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17981 (push_display_prop): xassert that we are iterating a buffer.

17985 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17986 correctly. Don't assume unibyte strings are not bidi-reordered.

17995 property. Fix a typo in popping stretch info. Add an assertion
17996 for verifying that the iterator position is in sync with the bidi
17998 (handle_single_display_spec, get_overlay_strings_1)

18410 (clone_per_buffer_values): Don't assume that

18412 This isn't true in general, and it's particularly not true
18413 if Emacs is configured with --with-wide-int.
18414 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
18415 New macros, used in the buffer.c change.

18451 Random fixes. E.g., (random) never returned negative values.
18452 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18453 subseconds part to the entropy, as that's a bit more random.
18454 Prefer signed to unsigned, since the signedness doesn't matter and
18455 in general we prefer signed. When given a limit, use a
18456 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18457 latter isn't right if USE_2_TAGS_FOR_INTS.
18458 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18459 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18471 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18472 This is more efficient than Ffile_directory_p and avoids a minor race.
18474 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18476 * buffer.c (Foverlay_put): Say what the return value is
18479 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18480 is a directory before asking whether to use the file name

18483 error be more correct.
18485 * fns.c (Frequire): Remove the mention of the .gz files, since
18486 that's installation-specific, but keep the mention of
18487 `get-load-suffixes'.

18491 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

18499 Qgnutls_bootprop_verify_error (which is no longer used).
18501 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18502 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18503 Also (re)move comments that are misplaced or no longer relevant.

18532 * lread.c (syms_of_lread): Mention single symbols defined by

18604 * eval.c (struct backtrace): Simplify and port the data structure.
18605 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18606 signed bit field, as this assumption is not portable and it makes
18607 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18608 "char debug_on_exit : 1" as this is not portable either; instead,
18609 use the portable "unsigned int debug_on_exit : 1". Remove unused
18610 member evalargs. Remove obsolete comments about cc bombing out.
18612 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18684 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
18685 and use min_width/height from frames size_hint to set
18686 min_width/height (Bug#8919).

18698 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
18700 * process.c (wait_reading_process_output): Bypass select if
18701 waiting for a cell while ignoring keyboard input, and input is
18702 pending. Suggested by Jan Djärv (Bug#8869).

18706 Use gnulib's dup2 module instead of rolling our own.
18707 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
18709 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18711 * dispnew.c (scrolling_window): Before scrolling, turn off a

18778 * print.c (printchar, strout): Check for string overflow.
18779 (PRINTPREPARE, printchar, strout):
18780 Don't set size unless allocation succeeds.
18782 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18783 for sizes. Check for string overflow more accurately.
18784 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
18786 * macros.c: Integer and buffer overflow fixes.
18787 * keyboard.h (struct keyboard.kbd_macro_bufsize):
18788 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

18792 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
18794 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
18796 * lread.c: Integer overflow fixes.
18797 (read_integer): Radix is now EMACS_INT, not int,
18798 to improve quality of diagnostics for out-of-range radices.
18799 Calculate buffer size correctly for out-of-range radices.
18800 (read1): Check for integer overflow in radices, and in
18801 read-circle numbers.
18802 (read_escape): Avoid int overflow.
18803 (Fload, openp, read_buffer_size, read1)
18804 (substitute_object_recurse, read_vector, read_list, map_obarray):

18820 2011-06-22 Leo Liu <sdl.web@gmail.com>
18822 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
18823 Move to minibuffer.el.
18825 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18827 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18828 The following patches are for when GLYPH_DEBUG && !XASSERT.
18829 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18830 * dispnew.c (flush_stdout):
18831 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18832 Mark as externally visible.
18833 * dispnew.c (check_window_matrix_pointers): Now static.
18834 * dispnew.c (window_to_frame_vpos):
18835 * xfns.c (unwind_create_frame):

18837 * scroll.c (CHECK_BOUNDS):
18838 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18839 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18840 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18841 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18842 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18844 (debug_method_add): Use va_list and vsprintf rather than relying
18845 on undefined behavior with wrong number of arguments.
18846 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18847 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18848 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18849 since we're not interested in debugging glyphs with old libraries.
18850 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18851 GCC 4.6.0's static checking.
18853 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

18871 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18872 (.bitmaps_last, struct x_output.icon_bitmap):
18873 Use ptrdiff_t, not int, for bitmap indexes.
18874 (x_allocate_bitmap_record): Check for size overflow.
18875 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18877 Use ptrdiff_t, not int, for overlay counts.
18878 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18879 * editfns.c (overlays_around, get_pos_property):

18881 * xdisp.c (next_overlay_change, note_mouse_highlight):
18882 * xfaces.c (face_at_buffer_position):
18883 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18884 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18885 (Fnext_overlay_change, Fprevious_overlay_change)
18886 (mouse_face_overlay_overlaps, Foverlays_in):
18887 Use ptrdiff_t, not int, for sizes.
18888 (overlays_at, overlays_in): Check for size-calculation overflow.
18890 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18892 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18893 (x_session_initialize): Do not assume string length fits in int.
18895 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18896 This is unlikely, but can occur if DPI is outlandish.
18898 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18899 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18901 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18902 * xrdb.c (magic_file_p, search_magic_path):
18903 Omit last arg SUFFIX; it was always 0. All callers changed.
18904 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18906 * xfont.c (xfont_match): Avoid need for strlen.
18908 * xfns.c: Don't assume strlen fits in int.

18911 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18912 not unsigned long, as we prefer signed integers. All callers changed.
18913 Detect integer overflow in repeat count.
18914 (message_dolog): Don't assume print length fits in 39 bytes.
18915 (display_mode_element): Don't assume strlen fits in int.
18917 * termcap.c: Don't assume sizes fit in int and never overflow.
18918 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.

18921 * minibuf.c (Fread_buffer):
18922 * lread.c (intern, intern_c_string):

18931 Use ptrdiff_t, not int.
18932 (font_intern_prop): Don't assume string length fits in int.
18933 Don't assume integer property fits in fixnum.
18934 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
18936 * filelock.c: Fix some buffer overrun and integer overflow issues.
18937 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
18938 Reformulate so as not to need the command string.
18939 Invoke gzip -cd rather than gunzip, as it's more portable.
18940 (lock_info_type, lock_file_1, lock_file):
18941 Don't assume pid_t and time_t fit in unsigned long.
18942 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18943 (current_lock_owner): Prefer signed type for sizes.
18944 Use memcpy, not strncpy, where memcpy is what is really wanted.
18945 Don't assume (via atoi) that time_t and pid_t fit in int.
18946 Check for time_t and/or pid_t out of range, e.g., via a network share.
18947 Don't alloca where an auto var works fine.
18949 * fileio.c: Fix some integer overflow issues.
18950 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18951 Don't assume string length fits in int.
18952 (directory_file_name): Don't assume string length fits in long.
18953 (make_temp_name): Don't assume pid fits in int, or that its print
18954 length is less than 20.

18974 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18976 * lread.c (invalid_syntax): Omit length argument.
18977 All uses changed. This doesn't fix a bug, but it simplifies the
18978 code away from its former Hollerith-constant appearance, and it's
18979 one less 'int' to worry about when looking at integer-overflow issues.
18980 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18982 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18983 This didn't break anything, but it didn't help either.
18984 It's confusing to put a bogus integer in a place where the actual
18985 value does not matter.
18986 (LIST_END_P): Remove unused macro and its bogus comment.
18987 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18989 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18990 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18992 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18993 We prefer signed types, and the value cannot exceed the EMACS_INT
18994 range anyway (because otherwise the length would not be representable).
18995 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18996 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18997 This avoids a GCC warning when WIDE_EMACS_INT.
18999 * indent.c (sane_tab_width): New function.
19000 (current_column, scan_for_column, Findent_to, position_indentation)
19001 (compute_motion): Use it. This is just for clarity.
19002 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.

19010 * editfns.c, insdel.c:
19011 Omit unnecessary forward decls, to simplify future changes.
19013 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19015 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19017 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19018 Use much-faster test for byte-length change.
19019 Don't assume string byte-length fits in 'int'.
19020 Check that character arg fits in 'int'.
19021 (mapcar1): Declare byte as byte, for clarity.
19023 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19025 * fns.c (concat): Catch string overflow earlier.
19026 Do not rely on integer wraparound.
19028 * dispextern.h (struct it.overlay_strings_charpos)
19029 (struct it.selective): Now EMACS_INT, not int.
19030 * xdisp.c (forward_to_next_line_start)
19031 (back_to_previous_visible_line_start)
19032 (reseat_at_next_visible_line_start, next_element_from_buffer):
19033 Don't arbitrarily truncate the value of 'selective' to int.
19035 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19037 * composite.c: Don't truncate sizes to 'int'.
19038 (composition_gstring_p, composition_reseat_it)
19039 (composition_adjust_point): Use EMACS_INT, not int.
19040 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19041 not EMACS_UINT, for indexes.
19043 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19045 * buffer.c: Include <verify.h>.
19046 (struct sortvec.priority, struct sortstr.priority):
19047 Now EMACS_INT, not int.
19048 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19049 (struct sortstr.size, record_overlay_string)
19050 (struct sortstrlist.size, struct sortlist.used):
19051 Don't truncate size to int.
19052 (record_overlay_string): Check for size-calculation overflow.
19053 (init_buffer_once): Check at compile-time, not run-time.
19055 2011-06-22 Jim Meyering <meyering@redhat.com>
19057 Don't leak an XBM-image-sized buffer
19058 * image.c (xbm_load): Free the image buffer after using it.
19060 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19063 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19064 that Sun C diagnosed.
19065 * fns.c (secure_hash): Fix pointer signedness issue.
19066 * intervals.c (static_offset_intervals): New function.
19067 (offset_intervals): Use it.
19069 2011-06-21 Leo Liu <sdl.web@gmail.com>
19072 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19075 * fns.c (secure_hash): Rename from crypto_hash_function and change
19076 the first arg to accept symbols.
19077 (Fsecure_hash): New primitive.
19078 (syms_of_fns): New symbols.
19080 2011-06-20 Deniz Dogan <deniz@dogan.se>
19082 * process.c (Fset_process_buffer): Clarify return value in

19093 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19096 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19097 check till after the cache is created in init_frame_faces.
19099 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19101 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19103 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19105 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19106 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19107 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19109 Improve buffer-overflow checking (Bug#8873).
19110 * fileio.c (Finsert_file_contents):
19111 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19112 Remove the old (too-loose) buffer overflow checks.
19113 They weren't needed, since make_gap checks for buffer overflow.
19114 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19115 The old code merely checked for Emacs fixnum overflow, and relied
19116 on undefined (wraparound) behavior. The new code avoids undefined
19117 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19119 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19120 Tune. Don't use wider integers than needed. Don't use alloca.
19121 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19123 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19125 * insdel.c, lisp.h (buffer_overflow): New function.
19126 (insert_from_buffer_1, replace_range, replace_range_2):
19127 * insdel.c (make_gap_larger):
19128 * editfns.c (Finsert_char):
19129 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19131 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19133 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19135 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19137 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19138 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19140 * fileio.c: Don't assume EMACS_INT fits in off_t.
19141 (emacs_lseek): New static function.
19142 (Finsert_file_contents, Fwrite_region): Use it.
19143 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19145 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19147 * fns.c: Don't overflow int when computing a list length.
19148 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19149 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19150 truncation on 64-bit hosts. Check for QUIT every
19151 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19152 faster and is responsive enough.
19153 (Flength): Report an error instead of overflowing an integer.
19154 (Fsafe_length): Return a float if the value is not representable
19155 as a fixnum. This shouldn't happen except in contrived situations.
19156 (Fnthcdr, Fsort): Don't assume list length fits in int.
19157 (Fcopy_sequence): Don't assume vector length fits in int.
19159 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19160 (header_size, word_size): New constants.
19161 (allocate_vectorlike): Don't check size overflow here.
19162 (allocate_vector): Check it here instead, since this is the only
19163 caller of allocate_vectorlike that could cause overflow.
19164 Check that the new vector's length is representable as a fixnum.
19166 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19167 The previous code was bogus. For example, next_almost_prime (32)
19168 returned 39, which is undesirable as it is a multiple of 3; and
19169 next_almost_prime (24) returned 25, which is a multiple of 5 so
19170 why was the code bothering to check for multiples of 7?
19172 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19174 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19176 Variadic C functions now count arguments with ptrdiff_t.
19177 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19178 Back then I didn't know that the Emacs coding style prefers signed int.
19179 Also, in the meantime I found a few more instances where arguments
19180 were being counted with int, which may truncate counts on 64-bit
19181 machines, or EMACS_INT, which may be unnecessarily wide.
19182 * lisp.h (struct Lisp_Subr.function.aMANY)
19183 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19184 Arg counts are now ptrdiff_t, not size_t.
19185 All variadic functions and their callers changed accordingly.
19186 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19187 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19188 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19189 * callint.c (Fcall_interactively): Check arg count for overflow,
19190 to avoid potential buffer overrun. Use signed char, not 'int',
19191 for 'varies' array, so that we needn't bother to check its size
19192 calculation for overflow.
19193 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19194 * eval.c (apply_lambda):
19195 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19196 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19197 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19199 * callint.c (Fcall_interactively): Don't use index var as event count.
19201 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19202 * mem-limits.h (SIZE): Remove; no longer used.
19204 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19206 Remove unnecessary casts.
19207 * xterm.c (x_term_init):
19208 * xfns.c (x_set_border_pixel):
19209 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19210 These aren't needed now that we assume ANSI C.
19212 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19213 It's more likely to cause problems (due to unsigned overflow)
19216 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19218 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19220 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19222 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19224 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19226 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19228 GLYPH_CODE_FACE returns EMACS_INT, not int.
19229 * dispextern.h (merge_faces):
19230 * xfaces.c (merge_faces):
19231 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19232 Don't assume EMACS_INT fits in int.
19234 * character.h (CHAR_VALID_P): Remove unused parameter.
19235 * fontset.c, lisp.h, xdisp.c: All uses changed.
19237 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19239 * fns.c (concat): Minor tuning based on overflow analysis.
19240 This doesn't fix any bugs. Use int to hold character, instead
19241 of constantly refetching from Emacs object. Use XFASTINT, not
19242 XINT, for value known to be a character. Don't bother comparing
19243 a single byte to 0400, as it's always less.
19245 * floatfns.c (Fexpt):
19246 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19248 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19251 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19253 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19254 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19255 incorrectly succeed when S was a string, because 4294967386 was
19256 truncated before it was used.
19258 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19259 Otherwise, an out-of-range integer could cause undefined behavior
19262 * composite.c: Use int, not EMACS_INT, for characters.
19263 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19264 EMACS_INT, for values that are known to be in character range.
19265 This doesn't fix any bugs but is the usual style inside Emacs and
19266 may generate better code on 32-bit machines.
19268 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19269 This is for reasons similar to the recent CHAR_STRING fix.
19270 * charset.c (Fencode_char): Check that character arg is actually
19271 a character. Pass an int to ENCODE_CHAR.
19272 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19273 wider than 'int', as a compile-time check to prevent future regressions
19276 * character.c (char_string): Remove unnecessary casts.
19278 Make sure a 64-bit char is never passed to CHAR_STRING.
19279 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19280 by silently ignoring the top 32 bits, allowing some values
19281 that were far too large to be valid characters.
19282 * character.h: Include <verify.h>.
19283 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19284 arguments are no wider than unsigned, as a compile-time check
19285 to prevent future regressions in this area.
19287 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19288 (Fsubst_char_in_region):
19290 * xdisp.c (decode_mode_spec_coding):
19291 Adjust to CHAR_STRING's new requirement.
19292 * editfns.c (Finsert_char, Fsubst_char_in_region):
19293 * fns.c (concat): Check that character args are actually
19294 characters. Without this test, these functions did the wrong
19295 thing with wildly out-of-range values on 64-bit hosts.
19297 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19298 These casts should not be needed on 32-bit hosts, either.
19299 * keyboard.c (read_char):
19300 * lread.c (Fload): Remove casts to unsigned.
19302 * lisp.h (UNSIGNED_CMP): New macro.
19303 This fixes comparison bugs on 64-bit hosts.
19304 (ASCII_CHAR_P): Use it.
19305 * casefiddle.c (casify_object):
19306 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19307 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19308 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19309 * dispextern.h (FACE_FROM_ID):
19310 * keyboard.c (read_char): Use UNSIGNED_CMP.
19312 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19313 not to EMACS_INT, to avoid GCC warning.
19315 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19317 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19318 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19319 isn't needed on 32-bit machines.
19321 * buffer.c (Fgenerate_new_buffer_name):
19322 Use EMACS_INT for count, not int.
19323 (advance_to_char_boundary): Return EMACS_INT, not int.
19325 * data.c (Qcompiled_function): Now static.
19327 * window.c (window_body_lines): Now static.
19329 * image.c (gif_load): Rename local to avoid shadowing.
19331 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19332 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19333 * alloc.c (make_save_value): Integer argument is now of type
19334 ptrdiff_t, not int.
19335 (mark_object): Use ptrdiff_t, not int.
19336 * lisp.h (pD): New macro.
19337 * print.c (print_object): Use it.
19339 * alloc.c: Use EMACS_INT, not int, to count objects.
19340 (total_conses, total_markers, total_symbols, total_vector_size)
19341 (total_free_conses, total_free_markers, total_free_symbols)
19342 (total_free_floats, total_floats, total_free_intervals)
19343 (total_intervals, total_strings, total_free_strings):
19344 Now EMACS_INT, not int. All uses changed.
19345 (Fgarbage_collect): Compute overall total using a double, so that
19346 integer overflow is less likely to be a problem. Check for overflow
19347 when converting back to an integer.
19348 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19349 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19350 These were 'int' variables that could overflow on 64-bit hosts;
19351 they were never used, so remove them instead of repairing them.
19352 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19353 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19354 Previously, this ceilinged at INT_MAX, but that doesn't work on
19356 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19358 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19359 (allocate_vectorlike): Check for ptrdiff_t overflow.
19360 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19361 when a (possibly-narrower) signed value would do just as well.
19362 We prefer using signed arithmetic, to avoid comparison confusion.
19364 * alloc.c: Catch some string size overflows that we were missing.
19365 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19366 for convenience in STRING_BYTES_MAX.
19367 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19368 The definition here is exact; the one in lisp.h was approximate.
19369 (allocate_string_data): Check for string overflow. This catches
19370 some instances we weren't catching before. Also, it catches
19371 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19372 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19373 and ptrdiff_t and EMACS_INT are both 64 bits.
19375 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19376 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19377 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19379 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19381 * alloc.c (Fmake_string): Check for out-of-range init.
19383 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19385 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
19387 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
19389 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
19390 xg_get_default_scrollbar_width.
19392 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
19393 (int_gtk_range_get_value): Move to the scroll bar part of the file.
19394 (style_changed_cb): Call update_theme_scrollbar_width and call
19395 x_set_scroll_bar_default_width and xg_frame_set_char_size for
19396 all frames (Bug#8505).
19397 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
19398 Call gtk_window_set_resizable if HAVE_GTK3.
19399 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
19400 and height if HAVE_GTK3 (Bug#8505).
19401 (scroll_bar_width_for_theme): New variable.
19402 (update_theme_scrollbar_width): New function.
19403 (xg_get_default_scrollbar_width): Move code to
19404 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
19405 (xg_initialize): Call update_theme_scrollbar_width.
19407 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
19409 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
19411 2011-06-12 Martin Rudalics <rudalics@gmx.at>
19413 * frame.c (make_frame): Call other_buffer_safely instead of
19416 * window.c (temp_output_buffer_show): Call display_buffer with
19417 second argument Vtemp_buffer_show_specifiers and reset latter
19418 immediately after the call.
19419 (Vtemp_buffer_show_specifiers): New variable.
19420 (auto_window_vscroll_p, next_screen_context_lines)
19421 (Vscroll_preserve_screen_position): Remove leading asterisks from
19424 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
19426 Fix minor problems found by GCC 4.6.0 static checking.
19427 * buffer.c (Qclone_number): Remove for now, as it's unused.
19428 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
19429 (record_buffer): Remove unused local.
19430 * frame.c (other_visible_frames, frame_buffer_list): Now static.
19431 (set_frame_buffer_list): Remove; unused.
19432 * frame.h (other_visible_frames): Remove decl.
19433 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
19434 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
19435 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
19437 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
19438 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
19439 Define only if HAVE_GPM.
19440 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
19441 (update_hints_inhibit): Remove; never set. All uses removed.
19442 * widgetprv.h (emacsFrameClassRec): Remove decl.
19443 * window.c (delete_deletable_window): Now returns void, since it
19444 wasn't returning anything.
19445 (compare_window_configurations): Remove unused locals.
19446 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
19447 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
19448 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
19449 the same widths as pointers. This follows up on the 2011-05-06 patch.
19450 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
19451 * xterm.h: Likewise.
19452 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
19454 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
19456 * makefile.w32-in: Update dependencies.
19457 (LISP_H): Add lib/intprops.h.
19459 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
19461 * image.c (gif_load): Add animation frame delay to the metadata.
19462 (syms_of_image): Use DEFSYM. New symbol `delay'.
19464 2011-06-11 Martin Rudalics <rudalics@gmx.at>
19466 * window.c (delete_deletable_window): Re-add.
19467 (Fset_window_configuration): Rewrite to handle dead buffers and
19468 consequently deletable windows.
19469 (window_tree, Fwindow_tree): Remove. Supply functionality in
19471 (compare_window_configurations): Simplify code.
19473 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
19475 * image.c (imagemagick_load_image): Fix type mismatch.
19476 (Fimagemagick_types): Likewise.
19478 * window.h (replace_buffer_in_windows): Declare.
19480 2011-06-11 Martin Rudalics <rudalics@gmx.at>
19482 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
19483 Qclone_number. Remove external declaration of Qdelete_window.
19484 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
19486 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
19487 Run Qbuffer_list_update_hook if allowed.
19488 (Fother_buffer): Rewrite doc-string. Major rewrite for new
19489 buffer list implementation.
19490 (other_buffer_safely): New function.
19491 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
19492 calls to replace_buffer_in_windows and
19493 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
19495 (record_buffer): Inhibit quitting and rewrite using quittable
19496 functions. Run Qbuffer_list_update_hook if allowed.
19497 (Frecord_buffer, Funrecord_buffer): New functions.
19498 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
19499 Move switch-to-buffer to window.el.
19500 (bury-buffer): Move to window.el.
19501 (Vbuffer_list_update_hook): New variable.
19503 * lisp.h (other_buffer_safely): Add prototype in buffer.c
19506 * window.h (resize_frame_windows): Move up in code.
19507 (Fwindow_frame): Remove EXFUN.
19508 (replace_buffer_in_all_windows): Remove prototype.
19509 (replace_buffer_in_windows_safely): Add prototype.
19511 * window.c: Declare Qdelete_window static again. Move down
19512 declaration of select_count.
19513 (Fnext_window, Fprevious_window): Rewrite doc-strings.
19514 (Fother_window): Move to window.el.
19515 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
19516 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
19517 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
19519 (replace_buffer_in_windows): Implement by calling
19520 Qreplace_buffer_in_windows.
19521 (replace_buffer_in_all_windows): Remove with some functionality
19522 moved into replace_buffer_in_windows_safely.
19523 (replace_buffer_in_windows_safely): New function.
19524 (select_window_norecord, select_frame_norecord): Move in front
19525 of run_window_configuration_change_hook. Remove now obsolete
19527 (Fset_window_buffer): Rewrite doc-string.
19528 Call Qrecord_window_buffer.
19529 (keys_of_window): Move binding for other-window to window.el.
19531 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
19533 * dispextern.h (struct image): Replace data member, whose int_val
19534 and ptr_val fields were not used by anything, with a single
19537 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
19538 (gif_clear_image, gif_load, imagemagick_load_image)
19539 (gs_clear_image, gs_load): Callers changed.

19983 (compute_display_string_pos): Accept additional argument
19984 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19985 value of a `display' property is a "replacing spec".
19986 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19987 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19988 the display property, but just return a value indicating whether
19989 the display property will replace the characters it covers.
19990 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19991 frame_window_p members of struct bidi_it.
19992 (compute_display_string_pos, compute_display_string_end):
19994 (push_it): Accept second argument POSITION, where pop_it should
19995 jump to continue iteration.
19996 (reseat_1): Initialize bidi_it.disp_pos.
19998 * keyboard.c (adjust_point_for_property): Adjust the call to
19999 display_prop_intangible_p to its new signature.
20001 * dispextern.h (struct bidi_it): New member frame_window_p.
20002 (bidi_init_it): Update prototypes.

20004 (compute_display_string_pos, compute_display_string_end):
20005 Declare prototypes.
20006 (struct bidi_it): New members nchars and disp_pos. ch_len is now
20009 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
20011 Malloc failure behavior now depends on size of allocation.
20012 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
20013 * lisp.h: Change signatures accordingly.
20014 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
20015 All callers changed. (Bug#8762)
20017 * gnutls.c: Use Emacs's memory allocators.
20018 Without this change, the gnutls library would invoke malloc etc.
20019 directly, which causes problems on non-SYNC_INPUT hosts, and which
20020 runs afoul of improving memory_full behavior. (Bug#8761)
20021 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20022 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20023 xfree instead of the default malloc, realloc, free.
20024 (Fgnutls_boot): No need to check for memory allocation failure,
20025 since xmalloc does that for us.
20027 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
20028 * category.c (hash_get_category_set):
20029 * ccl.c (ccl_driver):
20030 * charset.c (Fdefine_charset_internal):

20033 (composition_gstring_put_cache):
20034 * composite.h (struct composition.hash_index):
20035 * dispextern.h (struct image.hash):
20036 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
20037 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)

20041 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
20042 (Fsxhash, Fgethash, Fputhash, Fmaphash):
20043 * image.c (make_image, search_image_cache, lookup_image)
20044 (xpm_put_color_table_h):
20045 * lisp.h (struct Lisp_Hash_Table):
20046 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
20047 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
20048 for hashes and hash indexes, instead of 'unsigned' and 'int'.
20049 * alloc.c (allocate_vectorlike):
20050 Check for overflow in vector size calculations.
20051 * ccl.c (ccl_driver):
20052 Check for overflow when converting EMACS_INT to int.
20053 * fns.c, image.c: Remove unnecessary static decls that would otherwise
20054 need to be updated by these changes.
20055 * fns.c (make_hash_table, maybe_resize_hash_table):
20056 Check for integer overflow with large hash tables.
20057 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20058 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20059 (SXHASH_REDUCE): New macro.
20060 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20061 Use it instead of discarding useful hash info with large hash values.
20062 (sxhash_float): New function.
20063 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20064 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20065 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20066 Rewrite to use FIXNUM_BITS, as this simplifies things.
20067 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20068 Adjust signatures to match updated version of code.
20069 (consing_since_gc): Now EMACS_INT, since a single hash table can
20070 use more than INT_MAX bytes.
20072 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
20074 Make it possible to build with GCC-4.6+ -O2 -flto.
20076 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
20078 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
20080 * minibuf.c (get_minibuffer, read_minibuf_unwind):
20081 Call minibuffer-inactive-mode.
20083 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
20085 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
20086 Update dependencies.
20088 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20090 * data.c (init_data): Remove code for UTS, this system is not
20093 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20095 Don't force ./temacs to start in terminal mode.
20097 * frame.c (make_initial_frame): Initialize faces in all cases, not
20098 only when CANNOT_DUMP is defined.
20099 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
20101 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20103 * dispnew.c (add_window_display_history): Use const for the string
20104 pointer. Remove declaration, not needed.
20106 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20108 Use 'inline', not 'INLINE'.
20109 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20110 * alloc.c, fontset.c (INLINE): Remove.
20111 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20112 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20113 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20114 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20115 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20117 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20119 Make it possible to run ./temacs.
20121 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20122 syms_of_callproc does the same thing. Remove test for
20123 "initialized", do it in the caller.
20124 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20126 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20128 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20129 (read_minibuf): Use get_minibuffer.
20130 (syms_of_minibuf): Use DEFSYM.
20131 (Qmetadata): New var.
20132 * data.c (Qbuffer): Don't make it static.
20133 (syms_of_data): Use DEFSYM.
20135 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20137 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20138 (CCL_CODE_MIN): New macro.
20140 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20142 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20144 * eval.c (Qdebug): Now static.
20145 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20146 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20147 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20149 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20151 * image.c: Various fixes to ImageMagick code comments.
20152 (Fimagemagick_types): Doc fix.
20154 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20156 Minor fixes prompted by GCC 4.6.0 warnings.
20158 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20160 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20161 (x_clipboard_manager_save_all): Move extern decl to ...
20162 * xterm.h: ... here, so that it can be checked for consistency.
20164 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20166 * xselect.c (x_clipboard_manager_save_frame)
20167 (x_clipboard_manager_save_all): New functions.
20168 (Fx_clipboard_manager_save): Lisp function deleted.
20170 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20171 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20173 * xterm.h: Update prototype.
20175 2011-05-28 William Xu <william.xwl@gmail.com>
20177 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20178 exiting (Bug#8239).
20180 2011-05-28 Jim Meyering <meyering@redhat.com>
20182 Avoid a sign-extension bug in crypto_hash_function.
20183 * fns.c (to_uchar): Define.
20184 (crypto_hash_function): Use it to convert some newly-signed
20185 variables to unsigned, to avoid sign-extension bugs. For example,
20186 without this change, (md5 "truc") would evaluate to
20187 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20188 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20189 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20191 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20193 Integer overflow fixes.
20195 * dbusbind.c: Serial number integer overflow fixes.
20196 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20197 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20198 to hold a serial number that is too large for a fixnum.
20199 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20200 Check for serial numbers out of range. Decode any serial number
20201 that was so large that it became a float. (Bug#8722)
20203 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20204 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20205 Use XFASTINT rather than XUINT when numbers are nonnegative.
20206 (xd_append_arg, Fdbus_method_return_internal):
20207 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20208 arguments, check that Lisp number is nonnegative, rather than
20209 silently wrapping negative numbers around. (Bug#8722)
20210 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20213 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20215 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20217 ccl: Add integer overflow checks.
20218 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20219 (IN_INT_RANGE): New macros.
20220 (ccl_driver): Use them to check for integer overflow when
20221 decoding a CCL program. Many of the new checks are whether XINT (x)
20222 fits in int; it doesn't always, on 64-bit hosts. The new version
20223 doesn't catch all possible integer overflows, but it's an
20224 improvement. (Bug#8719)
20226 * alloc.c (make_event_array): Use XINT, not XUINT.
20227 There's no need for unsigned here.
20229 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20230 This follows up to the 2011-05-06 change that substituted uintptr_t
20231 for EMACS_INT. This case wasn't caught back then.
20233 Rework Fformat to avoid integer overflow issues.
20234 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20235 now (part of C89). Include <verify.h>.
20236 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20237 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20238 (Fformat): Avoid the prepass trying to compute sizes; it was only
20239 approximate and thus did not catch overflow reliably. Instead, walk
20240 through the format just once, formatting and computing sizes as we go,
20241 checking for integer overflow at every step, and allocating a larger
20242 buffer as needed. Keep track separately whether the format is
20243 multibyte. Keep only the most-recently calculated precision, rather
20244 than them all. Record whether each argument has been converted to
20245 string. Use EMACS_INT, not int, for byte and char and arg counts.
20246 Support field widths and precisions larger than INT_MAX. Avoid
20247 sprintf's undefined behavior with conversion specifications such as %#d
20248 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20249 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20250 formatting out-of-range floating point numbers with int
20251 formats. (Bug#8668)
20253 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20255 * data.c: Avoid integer truncation in expressions involving floats.
20256 * data.c: Include <intprops.h>.
20257 (arith_driver): When there's an integer overflow in an expression
20258 involving floating point, convert the integers to floating point
20259 so that the resulting value does not suffer from catastrophic
20260 integer truncation. For example, on a 64-bit host (* 4
20261 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20262 Do not rely on undefined behavior after integer overflow.
20264 merge count_size_as_multibyte, parse_str_to_multibyte
20265 * character.c, character.h (count_size_as_multibyte):
20266 Rename from parse_str_to_multibyte; all uses changed.
20267 Check for integer overflow.
20268 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20269 since it's now a duplicate of the other. This is more of
20270 a character than a buffer op, so better that it's in character.c.
20271 * fns.c, print.c: Adjust to above changes.
20273 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20275 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20277 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20279 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20280 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20281 (x_clipboard_manager_save): Now static.
20282 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20284 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20285 (crypto_hash_function): Now static.
20286 Fix pointer signedness problems. Avoid unnecessary initializations.
20288 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20290 * termhooks.h (Vselection_alist): Make it terminal-local.
20292 * terminal.c (create_terminal): Initialize it.
20294 * xselect.c: Support for clipboard managers.
20295 (Vselection_alist): Move to termhooks.h as terminal-local var.
20296 (LOCAL_SELECTION): New macro.
20297 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20298 (symbol_to_x_atom): Remove gratuitous arg.
20299 (x_handle_selection_request, lisp_data_to_selection_data)
20300 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20301 (x_own_selection, x_get_local_selection, x_convert_selection):
20302 New arg, specifying work frame. Use terminal-local Vselection_alist.
20303 (some_frame_on_display): Delete unused function.
20304 (Fx_own_selection_internal, Fx_get_selection_internal)
20305 (Fx_disown_selection_internal, Fx_selection_owner_p)
20306 (Fx_selection_exists_p): New optional frame arg.
20307 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20308 (x_handle_selection_clear): Don't treat other terminals with the
20309 same keyboard specially. Use the terminal-local Vselection_alist.
20310 (x_clear_frame_selections): Use Frun_hook_with_args.
20312 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20314 * xterm.h: Add support for those atoms.
20316 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20318 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20319 (converted_selections, conversion_fail_tag): New global variables.
20320 (x_selection_request_lisp_error): Free the above.
20321 (x_get_local_selection): Remove unnecessary code.
20322 (x_reply_selection_request): Args changed; handle arbitrary array
20323 of converted selections stored in converted_selections.
20324 Separate the XChangeProperty and SelectionNotify steps.
20325 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20326 (x_convert_selection): New function.
20327 (x_handle_selection_event): Simplify.
20328 (x_get_foreign_selection): Don't ignore incoming requests while
20329 waiting for an answer; this will fail when we implement
20330 SAVE_TARGETS, and seems unnecessary anyway.
20331 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20332 (Vx_sent_selection_functions): Doc fix.
20334 2011-05-26 Leo Liu <sdl.web@gmail.com>
20336 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20338 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20340 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20342 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20343 for fringe update if it has periodic bitmap.
20344 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20345 and fringe_bitmap_periodic_p.
20347 * fringe.c (get_fringe_bitmap_data): New function.
20348 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20349 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20350 row. Mark glyph row for fringe update if periodicity changed.
20352 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20353 for fringe update unless it has periodic bitmap.
20355 2011-05-25 Kenichi Handa <handa@m17n.org>
20357 * xdisp.c (get_next_display_element): Set correct it->face_id for
20358 a static composition.

20371 * gnutls.c: Remove unused macros.
20372 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20373 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20374 Remove macros that are defined and never used.
20375 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20377 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20379 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20380 (Fx_get_selection_internal): Minor cleanup.
20381 (Fx_own_selection_internal): Rename arguments for consistency with
20384 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>

20408 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20410 * systime.h (Time): Define only if emacs is defined.
20411 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20412 where the include path doesn't have X11/X.h by default. See
20413 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20415 2011-05-20 Kenichi Handa <handa@m17n.org>
20417 * composite.c (find_automatic_composition): Fix previous change.
20419 2011-05-20 Glenn Morris <rgm@gnu.org>
20421 * lisp.mk: New file, split from Makefile.in.
20422 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20423 (shortlisp): Remove.
20424 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20426 2011-05-19 Glenn Morris <rgm@gnu.org>
20428 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20429 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20430 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20431 (lisp): Set the order to that of loadup.el.
20432 (shortlisp): Make it a copy of $lisp.
20433 (SOME_MACHINE_LISP): Remove.
20434 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20435 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20437 2011-05-18 Kenichi Handa <handa@m17n.org>
20439 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20440 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20441 (find_automatic_composition): Mostly rewrite for efficiency.
20443 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20445 * makefile.w32-in: Update dependencies.
20447 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20449 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20450 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20452 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20454 Fix some integer overflow issues, such as string length overflow.
20456 * insdel.c (count_size_as_multibyte): Check for string overflow.
20458 * character.c (lisp_string_width): Check for string overflow.
20459 Use EMACS_INT, not int, for string indexes and lengths; in
20460 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20461 the resulting string length overflows an EMACS_INT; instead,
20462 report a string overflow if no precision given. When checking for
20463 precision exhaustion, use a check that cannot possibly have
20464 integer overflow. (Bug#8675)
20465 * character.h (lisp_string_width): Adjust to new signature.
20467 * alloc.c (string_overflow): New function.
20468 (Fmake_string): Use it. This doesn't change behavior, but saves
20469 a few bytes and will simplify future changes.
20470 * character.c (string_escape_byte8): Likewise.
20471 * lisp.h (string_overflow): New decl.
20473 Fixups, following up to the user-interface timestamp change.
20474 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20475 for UI timestamps, instead of unsigned long.
20476 * msdos.c (mouse_get_pos): Likewise.
20477 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20478 * w32gui.h (Time): Define by including "systime.h" rather than by
20479 declaring it ourselves. (Bug#8664)
20481 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20482 * image.c (clear_image_cache): Likewise.
20484 * term.c (term_mouse_position): Don't assume time_t wraparound.
20486 Be more systematic about user-interface timestamps.
20487 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20488 and sometimes 'EMACS_UINT', to represent these timestamps.
20489 This change causes it to use 'Time' uniformly, as that's what X uses.
20490 This makes the code easier to follow, and makes it easier to catch
20491 integer overflow bugs such as Bug#8664.
20492 * frame.c (Fmouse_position, Fmouse_pixel_position):
20493 Use Time, not unsigned long, for user-interface timestamps.
20494 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20495 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20496 * keyboard.h (last_event_timestamp): Likewise.
20497 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20498 * menu.h (xmenu_show): Likewise.
20499 * term.c (term_mouse_position): Likewise.
20500 * termhooks.h (struct input_event.timestamp): Likewise.
20501 (struct terminal.mouse_position_hook): Likewise.
20502 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20503 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20504 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20505 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20506 what it was before.
20507 * menu.h, termhooks.h: Include "systime.h", for Time.
20509 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20510 Don't assume that the difference between two unsigned long values
20511 can fit into an integer. At this point, we know button_down_time
20512 <= event->timestamp, so the difference must be nonnegative, so
20513 there's no need to cast the result if double-click-time is
20514 nonnegative, as it should be; check that it's nonnegative, just in
20515 case. This bug is triggered when events are more than 2**31 ms
20516 apart (about 25 days). (Bug#8664)
20518 * xselect.c (last_event_timestamp): Remove duplicate decl.
20519 (x_own_selection): Remove needless cast to unsigned long.
20521 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20522 that always fit in int. Use a sentinel instead of a counter, to
20523 avoid a temp and to allay GCC's concerns about possible int overflow.
20524 * frame.h (struct frame): Use int for menu_bar_items_used
20525 instead of EMACS_INT, since it always fits in int.
20527 * menu.c (grow_menu_items): Check for int overflow.
20529 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20531 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20532 Before, the code was not consistent. These values cannot exceed
20533 2**31 - 1 so there's no need to make them unsigned.
20534 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20535 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20536 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20538 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20540 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20541 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20542 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20543 presumably because the widths might not match.
20545 * window.c (size_window): Avoid needless test at loop start.
20547 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20549 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20551 2011-05-12 Drew Adams <drew.adams@oracle.com>
20553 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20555 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20557 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20558 `width' to `bar_area_x' and `bar_area_width', respectively.
20559 (x_scroll_run): Take account of fringe background extension.
20561 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20562 Rename local vars `left' and `width' to `bar_area_x' and
20563 `bar_area_width', respectively.
20564 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20565 background extension.
20567 2011-05-10 Jim Meyering <meyering@redhat.com>
20569 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20571 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20573 * image.c (Finit_image_library): Return t for built-in image types,
20574 like pbm and xbm. (Bug#8640)
20576 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20578 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20580 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20582 * w32console.c (Fset_screen_color): Doc fix.
20583 (Fget_screen_color): New function.
20584 (syms_of_ntterm): Defsubr it.
20586 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20587 unlink the temporary file if Fcall_process didn't create it in the
20589 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20590 child process will be redirected to a file specified with `:file'.
20591 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20592 cue to call_process_cleanup not to close that handle.
20594 2011-05-07 Ben Key <bkey76@gmail.com>
20596 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20597 one of two shell specific rules, either bootstrap-temacs-CMD or
20598 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20599 to the previous implementation of the bootstrap-temacs rule.
20600 The bootstrap-temacs-CMD rule is similar to the previous
20601 implementation of the bootstrap-temacs rule except that it
20602 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20605 These changes, along with some changes to nt/configure.bat,
20606 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20607 earlier fix to add support for --cflags and --ldflags options
20608 that include quotes so that it works whether make uses cmd or
20611 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20613 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20614 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20616 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20617 a string. Handle both cases.
20618 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20619 (Fdbus_register_method): Use Qinvalid_function.
20621 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20623 * makefile.w32-in: Update dependencies.
20624 (LISP_H): Add inttypes.h and stdin.h.
20625 (PROCESS_H): Add unistd.h.
20627 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20629 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20630 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20632 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20634 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20636 * term.c (vfatal): Remove stray call to va_end.
20637 It's not needed and the C Standard doesn't allow it here anyway.
20639 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20640 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20642 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20645 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20647 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20649 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20651 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20653 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20655 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20656 * charset.c (Fdefine_charset_internal): Don't initialize
20657 charset.code_space[15]. The value was garbage, on hosts with
20658 32-bit int (Bug#8600).
20660 * lread.c (read_integer): Be more consistent with string-to-number.
20661 Use string_to_number to do the actual conversion; this avoids
20662 rounding errors and fixes some other screwups. Without this fix,
20663 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20664 (digit_to_number): Move earlier, for benefit of read_integer.
20665 Return -1 if the digit is out of range for the base, -2 if it is
20666 not a digit in any supported base. (Bug#8602)
20668 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20670 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20671 to match comment at start of function. This also removes a
20672 GCC warning about overflow in a 32+64-bit port.
20674 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20676 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20677 Reported by Stefan Monnier in
20678 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20679 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20680 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20682 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20683 (EMACS_UINTPTR): Likewise, with uintptr_t.
20685 * lisp.h: Prefer 64-bit EMACS_INT if available.
20686 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20687 on 32-bit hosts that have 64-bit int, so that they can access
20689 However, temporarily disable this change unless the temporary
20690 symbol WIDE_EMACS_INT is defined.
20692 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20694 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20695 This removes an assumption that EMACS_INT and long are the same
20696 width as pointers. The assumption is true for Emacs porting targets
20697 now, but we want to make other targets possible.
20698 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20699 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20700 In the rest of the code, change types of integers that hold casted
20701 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20702 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20703 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20704 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20705 No need to cast type when ORing.
20706 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20707 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20708 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20709 assume EMACS_INT is the same width as char *.
20710 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20711 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20712 Remove no-longer-needed casts.
20713 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20714 (xg_tool_bar_help_callback, xg_make_tool_item):
20715 Use EMACS_INTPTR to hold an integer
20716 that will be cast to void *; this can avoid a GCC warning
20717 if EMACS_INT is not the same width as void *.
20718 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20719 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20720 (current_message_1, set_message_1):
20721 Use a local to convert to proper width without a cast.
20722 * xmenu.c (dialog_selection_callback): Likewise.
20724 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20725 Also, don't assume VALBITS / RAND_BITS is less than 5,
20726 and don't rely on undefined behavior when shifting a 1 left into
20728 * lisp.h (get_random): Change signature to match.
20730 * lread.c (hash_string): Use size_t, not int, for hash computation.
20731 Normally we prefer signed values; but hashing is special, because
20732 it's better to use unsigned division on hash table sizes so that
20733 the remainder is nonnegative. Also, size_t is the natural width
20734 for hashing into memory. The previous code used 'int', which doesn't
20735 retain enough info to hash well into very large tables.
20736 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20738 * dbusbind.c: Don't possibly lose pointer info when converting.
20739 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20740 Use XPNTR rather than XHASH, so that the high-order bits of
20741 the pointer aren't lost when converting through void *.
20743 * eval.c (Fautoload): Don't double-shift a pointer.
20745 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20747 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20749 * gnutls.c (DEF_GNUTLS_FN):
20750 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20752 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20754 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20757 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20759 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20760 New version that can reserve upto 2GB of heap space.
20762 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20764 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20766 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20768 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20769 `gnutls_certificate_set_x509_key_file'.
20771 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20773 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20774 Update dependencies.
20776 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20778 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20779 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20780 Remove unused parameter `fildes'.
20781 * process.c (read_process_output, send_process): Don't pass it.
20783 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20785 Fix previous change: the library cache is defined in w32.c.
20786 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20787 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20789 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20791 Implement dynamic loading of GnuTLS on Windows.
20793 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20794 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20795 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20798 * gnutls.c (Qgnutls_dll): Define.
20799 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
20800 (gnutls_*): Declare function pointers.
20801 (init_gnutls_functions): New function to initialize function pointers.
20802 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
20803 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
20804 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20805 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
20806 (emacs_gnutls_write, emacs_gnutls_read)
20807 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20808 (Fgnutls_available_p): New function.
20809 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
20810 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
20811 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
20813 * image.c: Include w32.h.
20814 (Vimage_type_cache): Delete.
20815 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
20816 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
20817 (w32_delayed_load): Move to w32.c.
20819 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20821 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20822 (w32_delayed_load): Move from image.c. When loading a library, record
20823 its filename in the :loaded-from property of the library id.
20824 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20825 Initialize and staticpro them.
20826 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20828 * process.c: Include lisp.h before w32.h, not after.
20829 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20830 instead of gnutls_record_check_pending.
20832 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20834 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20836 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20837 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20840 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20842 * xterm.c (x_set_frame_alpha): Do not set property on anything

20865 * sysdep.c (wait_for_termination_1): Make static.
20866 (wait_for_termination, interruptible_wait_for_termination):
20867 Move after wait_for_termination_1.

20871 * sysdep.c (interruptible_wait_for_termination): New function
20872 which is like wait_for_termination, but allows keyboard
20875 * callproc.c (Fcall_process): Add (:file "file") as an option for
20877 (Fcall_process_region): Ditto.
20879 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20881 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20882 rather than `XVECTOR (FOO)->size'.
20884 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20885 inttypes.h, as a gnulib replacement is used if it not available in
20888 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20890 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20891 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20892 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20894 * coding.c (coding_alloc_by_realloc): Error out if destination
20895 will grow beyond MOST_POSITIVE_FIXNUM.
20896 (decode_coding_emacs_mule): Abort if there isn't enough place in
20897 charbuf for the composition carryover bytes. Reserve an extra
20898 space for up to 2 characters produced in a loop.
20899 (decode_coding_iso_2022): Abort if there isn't enough place in
20900 charbuf for the composition carryover bytes.
20902 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20904 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
20905 aborting when %lld or %lll format is passed.
20906 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20907 %llo or %llx format is passed. (Bug#8545)
20909 * window.c (window_scroll_line_based): Use a marker instead of
20910 simple variables to record original value of point. (Bug#7952)
20912 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20913 produced by %s or %c overflows available buffer space. (Bug#8545)
20915 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20917 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20918 (SIZE_MAX): Move defn after all includes, as they might #define it.
20920 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20922 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20924 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20926 * keyboard.c (Qdelayed_warnings_hook): Define.
20927 (command_loop_1): Run `delayed-warnings-hook'
20928 if Vdelayed_warnings_list is non-nil.
20929 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20930 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20932 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20934 * doprnt.c (doprnt): Don't return value smaller than the buffer
20935 size if the message was truncated. (Bug#8545).
20937 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20939 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20940 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20942 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20944 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20946 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20948 * makefile.w32-in: Update dependencies.
20950 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20952 Improve `doprnt' and its usage. (Bug#8545)
20953 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20954 `format_end'. Remove support for %l as a conversion specifier.
20955 Don't use xrealloc. Improve diagnostics when the %l size modifier
20956 is used. Update the commentary.
20958 * eval.c (verror): Simplify calculation of size_t.
20960 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20963 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20965 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20968 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20970 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20971 This makes this file independent of the recent pseudovector change.
20973 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20975 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20977 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20978 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20979 Remove unused local.
20980 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20982 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20983 GCC 4.6.0 optimizes based on type-based alias analysis.
20984 For example, if b is of type struct buffer * and v of type struct
20985 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20986 != &v->size, and therefore "v->size = 1; b->size = 2; return
20987 v->size;" must therefore return 1. This assumption is incorrect
20988 for Emacs, since it type-puns struct Lisp_Vector * with many other
20989 types. To fix this problem, this patch adds a new type struct
20990 vectorlike_header that documents the constraints on layout of vectors
20991 and pseudovectors, and helps optimizing compilers not get fooled
20992 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20993 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20994 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20996 (XSETPVECTYPE): Rewrite in terms of new macro.
20997 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20998 This is a bit clearer, and further avoids the possibility of
20999 undesirable aliasing.
21000 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21001 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21002 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21003 since Lisp_Subr is a special case (no "next" field).
21004 (ASIZE): Now uses header.size rather than size.
21005 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21006 to avoid the hassle of writing XVECTOR (foo)->header.size.
21007 (struct vectorlike_header): New type.
21008 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21009 object, to help avoid aliasing.
21010 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21011 (SUBRP): Likewise, since Lisp_Subr is a special case.
21012 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21013 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21014 (struct Lisp_Hash_Table): Combine first two members into a single
21015 struct vectorlike_header member. All uses of "size" and "next" members
21016 changed to be "header.size" and "header.next".
21017 * buffer.h (struct buffer): Likewise.
21018 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21019 * frame.h (struct frame): Likewise.
21020 * process.h (struct Lisp_Process): Likewise.
21021 * termhooks.h (struct terminal): Likewise.
21022 * window.c (struct save_window_data, struct saved_window): Likewise.
21023 * window.h (struct window): Likewise.
21024 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21025 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21026 * buffer.c (init_buffer_once): Likewise.
21027 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21029 * process.c (Fformat_network_address): Use local var for size,
21032 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21034 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21035 * data.c (atof): Remove decl; no longer used or needed.
21036 (digit_to_number): Move to lread.c.
21037 (Fstring_to_number): Use new string_to_number function, to be
21038 consistent with how the Lisp reader treats infinities and NaNs.
21039 Do not assume that floating-point numbers represent EMACS_INT
21040 without losing information; this is not true on most 64-bit hosts.
21041 Avoid double-rounding errors, by insisting on integers when
21042 parsing non-base-10 numbers, as the documentation specifies.
21043 * lisp.h (string_to_number): New decl, replacing ...
21044 (isfloat_string): Remove.
21045 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21046 (read1): Do not accept +. and -. as integers; this
21047 appears to have been a coding error. Similarly, do not accept
21048 strings like +-1e0 as floating point numbers. Do not report
21049 overflow for integer overflows unless the base is not 10 which
21050 means we have no simple and reliable way to continue.
21051 Break out the floating-point parsing into a new
21052 function string_to_number, so that Fstring_to_number parses
21053 floating point numbers consistently with the Lisp reader.
21054 (digit_to_number): Move here from data.c. Make it static inline.
21055 (E_CHAR, EXP_INT): Remove, replacing with ...
21056 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21057 (string_to_number): New function, replacing isfloat_string.
21058 This function checks for valid syntax and produces the resulting
21059 Lisp float number too. Rework it so that string-to-number
21060 no longer mishandles examples like "1.0e+". Use strtoumax,
21061 so that overflow for non-base-10 numbers is reported only when
21062 there's no portable and simple way to convert to floating point.
21064 * textprop.c (set_text_properties_1): Rewrite for clarity,
21065 and to avoid GCC warning about integer overflow.
21067 * intervals.h (struct interval): Use EMACS_INT for members
21068 where EMACS_UINT might cause problems. See
21069 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21070 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21071 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21073 (offset_intervals): Tell GCC not to worry about length overflow
21074 when negating a negative length.
21076 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21077 (overrun_check_free): Likewise.
21079 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21080 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21083 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21084 (gnutls_make_error): Rename local to avoid shadowing.
21085 (gnutls_emacs_global_deinit): ifdef out; not used.
21086 (Fgnutls_boot): Use const for pointer to readonly storage.
21087 Comment out unused local. Fix pointer signedness problems.
21089 * lread.c (openp): Don't stuff size_t into an 'int'.
21090 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21091 about possible signed overflow.
21093 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21094 (GDK_KEY_g): Don't define if already defined.
21095 (xg_prepare_tooltip): Avoid pointer signedness problem.
21096 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21098 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21099 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21101 * xfns.c (Fx_window_property): Simplify a bit,
21102 to make a bit faster and to avoid GCC 4.6.0 warning.
21103 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21105 * fns.c (internal_equal): Don't assume size_t fits in int.
21107 * alloc.c (compact_small_strings): Tighten assertion a little.
21109 Replace pEd with more-general pI, and fix some printf arg casts.
21110 * lisp.h (pI): New macro, generalizing old pEd macro to other
21111 conversion specifiers. For example, use "...%"pI"d..." rather
21112 than "...%"pEd"...".
21113 (pEd): Remove. All uses replaced with similar uses of pI.
21114 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21115 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21116 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21117 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21118 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21119 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21120 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21122 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21123 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21124 * print.c (safe_debug_print, print_object): Likewise.
21125 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21127 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21128 avoiding the 0 flag, which is not portable.
21129 * process.c (Fmake_network_process): Use pI to avoid cast.
21130 * region-cache.c (pp_cache): Likewise.
21131 * xdisp.c (decode_mode_spec): Likewise.
21132 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21133 behavior on 64-bit hosts with printf arg.
21134 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21135 (x_stop_queuing_selection_requests): Likewise.
21136 (x_get_window_property): Don't truncate byte count to an 'int'
21139 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21140 here, since it parses constructs like leading '-' and spaces,
21141 which are not wanted; and it overflows with large numbers.
21142 Instead, simply match F[0-9]+, which is what is wanted anyway.
21144 * alloc.c: Remove unportable assumptions about struct layout.
21145 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21146 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21147 (allocate_vectorlike, make_pure_vector): Use the new macros,
21148 plus offsetof, to remove unportable assumptions about struct layout.
21149 These assumptions hold on all porting targets that I know of, but
21150 they are not guaranteed, they're easy to remove, and removing them
21151 makes further changes easier.
21153 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21154 This doesn't fix a bug but makes the code clearer.
21155 (string_overrun_cookie): Now const. Use initializers that
21156 don't formally overflow signed char, to avoid warnings.
21157 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21158 can cause Emacs to crash when string overrun checking is enabled.
21159 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21160 multiple of sizeof (EMACS_INT); it need not be, if
21161 alignof(EMACS_INT) < sizeof (EMACS_INT).
21162 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21164 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
21166 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
21168 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
21170 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
21171 supposed to be handshaking. (Bug#8556)
21172 Reported by Paul Eggert <eggert@cs.ucla.edu>.

21176 * lisp.h (Qdebug): List symbol.
21177 * eval.c (Qdebug): Restore global linkage.
21178 * keyboard.c (debug-on-event): New variable.
21179 (handle_user_signal): Break into debugger when debug-on-event
21180 matches the current signal symbol.
21182 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
21184 * alloc.c (check_sblock, check_string_bytes)
21185 (check_string_free_list): Convert to standard C.
21187 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
21189 * w32.c (emacs_gnutls_push): Fix typo.
21191 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21193 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21194 "cast to pointer from integer of different size".
21196 Improve doprnt and its use in verror. (Bug#8545)
21197 * doprnt.c (doprnt): Document the set of format control sequences
21198 supported by the function. Use SAFE_ALLOCA instead of always
21201 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21202 is one byte too soon. Don't use xrealloc; instead xfree and
21205 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21207 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21210 * gnutls.c: Renamed global_initialized to
21211 gnutls_global_initialized. Added internals for the
21212 :verify-hostname-error, :verify-error, and :verify-flags
21213 parameters of `gnutls-boot' and documented those parameters in the
21214 docstring. Start callback support.
21215 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21216 unless a fatal error occurred. Call gnutls_alert_send_appropriate
21217 on error. Return error code.
21218 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
21219 (emacs_gnutls_read): Likewise.
21220 (Fgnutls_boot): Return handshake error code.
21221 (emacs_gnutls_handle_error): New function.
21222 (wsaerror_to_errno): Likewise.
21224 * w32.h (emacs_gnutls_pull): Add prototype.
21225 (emacs_gnutls_push): Likewise.
21227 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
21228 (emacs_gnutls_push): Likewise.
21230 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
21232 * process.c (wait_reading_process_output): Check if GnuTLS
21233 buffered some data internally if no FDs are set for TLS
21236 * makefile.w32-in (OBJ2): Add gnutls.$(O).
21237 (LIBS): Link to USER_LIBS.
21238 ($(BLD)/gnutls.$(0)): New target.

21242 * xdisp.c (handle_single_display_spec): Rename the
21243 display_replaced_before_p argument into display_replaced_p, to
21244 make it consistent with the commentary. Fix typos in the
21247 * textprop.c (syms_of_textprop): Remove dead code.
21248 (copy_text_properties): Delete obsolete commentary about an
21249 interface that was deleted long ago. Fix typos in the description

21253 to changes in oldXMenu/XMenu.h from 2011-04-16.
21254 <menu_help_message, prev_menu_help_message>: Constify.
21255 (IT_menu_make_room): menu->help_text is now `const char **';
21258 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
21259 to changes in oldXMenu/XMenu.h from 2011-04-16.
21260 (struct XMenu): Declare `help_text' `const char **'.

21522 ns_descriptor_to_entity that were caused by using free to
21523 deallocate memory blocks that were allocated by xmalloc (via

21545 * process.c (send_process): Adjust to the new signatures of
21546 emacs_write and emacs_gnutls_write. Do not attempt to store

21740 * font.h (font_close_object): Remove.
21741 * fontset.c (FONTSET_OBJLIST): Remove.
21742 (free_realized_fontset) #if-0 the body, which does nothing.
21743 (face_suitable_for_char_p): #if-0, as it's never called.
21744 * fontset.h (face_suitable_for_char_p): Remove decl.
21745 * xfaces.c (face_at_string_position):
21746 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
21747 since 0 is always ASCII.
21749 * fns.c (weak_hash_tables): Now static.
21751 * fileio.c: Make symbols static if they're not exported.
21752 (auto_saving, auto_save_mode_bits, auto_save_error_occurred):

21766 * lisp.h (fatal_error_signal_hook): Remove decl.
21767 (fatal_error_signal): Declare only if FLOAT_CATCH_SIGKILL.

21770 * editfns.c, lisp.h (get_operating_system_release): Remove.
21771 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
21772 worth the hassle of breaking this out.
21774 * xterm.c: Make symbols static if they're not exported.
21775 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

21878 * buffer.c (buffer_count): Remove unused var.
21880 * bidi.c (bidi_dump_cached_states): Mark as externally visible,

21887 * atimer.h (run_all_atimers): Remove; not exported.
21889 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
21890 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
21891 was inaccessible from Lisp.
21892 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
21893 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
21895 alloc.c: Import and export fewer symbols, and remove unused items.
21896 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
21898 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
21899 it's not optimized away by whole-program optimization.
21900 (message_enable_multibyte, free_misc): Remove.
21901 (catchlist, handlerlist, mark_backtrace):
21902 Declare only if BYTE_MARK_STACK.

21911 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
21912 (mark_backtrace): Define only if BYTE_MARK_STACK.
21913 * xdisp.c (message_enable_multibyte): Now static.
21915 Declare Lisp_Object Q* variables to be 'static' if not exported.
21916 This makes it easier for human readers (and static analyzers)
21917 to see whether these variables are used from other modules.
21918 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
21919 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
21920 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

21928 Remove decls of unexported vars.
21929 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
21931 * lisp.h (DEFINE_FUNC): Make sname 'static'.
21933 Make Emacs functions such as Fatom 'static' by default.
21934 This makes it easier for human readers (and static analyzers)
21935 to see whether these functions can be called from other modules.
21936 DEFUN now defines a static function. To make the function external
21937 so that it can be used in other C modules, use the new macro DEFUE.
21938 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
21939 (Finit_image_library):
21940 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
21941 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
21942 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
21943 Remove decls, since these functions are now static.
21944 (Funintern, Fget_internal_run_time): New decls, since these functions
21945 were already external.
21947 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
21948 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

21954 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
21955 Mark functions with DEFUE instead of DEFUN,
21956 if they are used in other modules.
21957 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
21958 decls for now-static functions.
21959 * buffer.h (Fdelete_overlay): Remove decl.
21960 * callproc.c (Fgetenv_internal): Mark as internal.

21969 * image.c (Finit_image_library): New forward static decl.
21970 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
21971 * intervals.h (Fprevious_property_change):
21972 (Fremove_list_of_text_properties): Remove decls.
21973 * keyboard.c (Fthis_command_keys): Remove decl.
21974 (Fcommand_execute): New forward static decl.

21990 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
21992 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21995 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21997 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21998 when at ZV. (Bug#8487)
22000 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22002 * charset.c (Fclear_charset_maps): Use xfree instead of free.
22004 * keyboard.c (parse_tool_bar_item): Likewise.
22005 * sound.c (sound_cleanup, alsa_close): Likewise.
22006 * termcap.c (tgetent): Likewise.
22007 * xfns.c (x_default_font_parameter): Likewise.
22008 * xsettings.c (read_and_apply_settings): Likewise.
22010 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22011 (overrun_check_free): Protoize.
22013 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22015 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22016 since callers should never pass a negative size.
22017 Change the signature to match that of plain 'read' and 'write'; see
22018 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22019 * lisp.h: Update prototypes of emacs_write and emacs_read.
22021 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22023 * xdisp.c (redisplay_window): Don't try to determine the character
22024 position of the scroll margin if the window start point w->startp
22025 is outside the buffer's accessible region. (Bug#8468)
22027 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22029 Fix write-region and its subroutines for buffers > 2GB.
22030 * fileio.c (a_write, e_write): Modify declaration of arguments and
22031 local variables to support buffers larger than 2GB.
22032 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22034 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22035 argument, local variables, and return value.
22037 * lisp.h: Update prototypes of emacs_write and emacs_read.
22039 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22041 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22043 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22045 Fix more problems found by GCC 4.6.0's static checks.
22047 * xdisp.c (vmessage): Use a better test for character truncation.
22049 * charset.c (load_charset_map): <, not <=, for optimization,
22050 and to avoid potential problems with integer overflow.
22051 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22052 * casetab.c (set_identity, shuffle): Likewise.
22053 * editfns.c (Fformat): Likewise.
22054 * syntax.c (skip_chars): Likewise.
22056 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22057 This also lets GCC 4.6.0 generate slightly better loop code.
22059 * callint.c (Fcall_interactively): <, not <=, for optimization.
22060 (Fcall_interactively): Count the number of arguments produced,
22061 not the number of arguments given. This is simpler and lets GCC
22062 4.6.0 generate slightly better code.
22064 * ftfont.c: Distingish more carefully between FcChar8 and char.
22065 The previous code passed unsigned char * to a functions like
22066 strlen and xstrcasecmp that expect char *, which does not
22067 conform to the C standard.
22068 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22069 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22070 char * when the C standard requires it.
22072 * keyboard.c (read_char): Remove unused var.
22074 * eval.c: Port to Windows vsnprintf (Bug#8435).
22075 Include <limits.h>.
22076 (SIZE_MAX): Define if the headers do not.
22077 (verror): Do not give up if vsnprintf returns a negative count.
22078 Instead, grow the buffer. This ports to Windows vsnprintf, which
22079 does not conform to C99. Problem reported by Eli Zaretskii.
22080 Also, simplify the allocation scheme, by avoiding the need for
22081 calling realloc, and removing the ALLOCATED variable.
22083 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22085 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22086 But keep the doprint source code for now, as we might revamp it
22087 and use it again (Bug#8435).
22088 * lisp.h (doprnt): Remove.
22089 * Makefile.in (base_obj): Remove doprnt.o.
22090 * deps.mk (doprnt.o): Remove.
22092 error: Print 32- and 64-bit integers portably (Bug#8435).
22093 Without this change, on typical 64-bit hosts error ("...%d...", N)
22094 was used to print both 32- and 64-bit integers N, which relied on
22095 undefined behavior.
22096 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22097 * lisp.h (error, verror): Mark as printf-like functions.
22098 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22099 Report overflow in size calculations when allocating printf buffer.
22100 Do not truncate output string at its first null byte.
22101 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22102 Truncate the output at a character boundary, since vsnprintf does not
22104 * charset.c (check_iso_charset_parameter): Convert internal
22105 character to string before calling 'error', since %c now has the
22107 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22108 overflow when computing char to be passed to 'error'. Do not
22109 pass Lisp_Object to 'error'; pass the integer instead.
22110 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22111 formatted with plain %d.
22113 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22115 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22117 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22119 * xterm.c (x_catch_errors): Remove duplicate declaration.
22121 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22123 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22125 2011-04-10 Jim Meyering <meyering@redhat.com>
22127 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22128 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22129 return ssize_t not "int", and use size_t as the buffer length.
22130 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22131 * gnutls.h: Update declarations.
22132 * process.c (read_process_output): Use ssize_t, to match.
22133 (send_process): Likewise.
22135 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22137 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22139 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22141 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22142 Use unsigned char, to match FcChar8 type definition.
22144 * xterm.c (handle_one_xevent):
22145 * xmenu.c (create_and_show_popup_menu):
22146 * xselect.c (x_decline_selection_request)
22147 (x_reply_selection_request): Avoid type-punned deref of X events.
22149 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22151 Fix some uses of `int' instead of EMACS_INT.
22152 * search.c (string_match_1, fast_string_match)
22153 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22154 (scan_buffer, find_next_newline_no_quit)
22155 (find_before_next_newline, search_command, Freplace_match)

22205 instead of using internal_with_output_to_temp_buffer.
22206 (Qhelp_form_show): New var.
22207 (syms_of_keyboard): Use DEFSYM macro.
22209 * print.c (internal_with_output_to_temp_buffer): Function deleted.

22245 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22247 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22248 This avoids several warnings with gcc -Wstrict-overflow.
22249 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22250 directly, rather than having caller test rule sign. This avoids
22251 some unnecessary tests.
22252 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22253 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22254 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22256 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22257 (xfont_open): Avoid unnecessary tests.
22259 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22261 * composite.h, composite.c (composition_gstring_put_cache):
22262 Use EMACS_INT, not int, for length.
22264 * composite.h (COMPOSITION_DECODE_REFS): New macro,
22265 breaking out part of COMPOSITION_DECODE_RULE.
22266 (COMPOSITION_DECODE_RULE): Use it.
22267 * composite.c (get_composition_id): Remove unused local vars,
22268 by using the new macro.
22270 * textprop.c (set_text_properties_1): Change while to do-while,
22271 since the condition is always true at first.
22273 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22274 (interval_deletion_adjustment): Return unsigned value.
22277 * process.c (list_processes_1, create_pty, read_process_output):

22279 (create_pty): Remove unnecessary "volatile"s.
22280 (Fnetwork_interface_info): Avoid possibility of int overflow.

22293 * print.c (print_error_message): Avoid int overflow.
22295 * font.c (font_list_entities): Redo for clarity,
22296 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22298 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22299 (font_score): Avoid potential overflow in diff calculation.

22304 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22306 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22307 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22308 can always succeed if overflow has undefined behavior.
22310 * search.c (boyer_moore, wordify): Remove vars set but not used.
22311 (wordify): Omit three unnecessary tests.
22313 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

22322 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22323 (Finsert_file_contents): Remove unnecessary code checking fd.
22325 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22326 Check for integer overflow on size calculations.
22328 * buffer.c (Fprevious_overlay_change): Remove var that is set
22331 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22332 Remove vars that are set but not used.
22333 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22334 (timer_check_2): Mark vars as initialized.
22336 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22338 * image.c (lookup_image): Remove var that is set but not used.
22339 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22341 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22342 that are set but not used.
22344 * xfns.c (make_invisible_cursor): Don't return garbage
22345 if XCreateBitmapFromData fails (Bug#8410).
22347 * xselect.c (x_get_local_selection, x_handle_property_notify):
22348 Remove vars that are set but not used.
22350 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
22351 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
22353 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
22354 Remove var that is set but not used.
22355 (scroll_bar_windows_size): Now size_t, not int.
22356 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
22357 Check for overflow.
22359 * xfaces.c (realize_named_face): Remove vars that are set but not used.
22360 (map_tty_color) [!defined MSDOS]: Likewise.
22362 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22364 * coding.c: Remove vars that are set but not used.
22365 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22366 All callers changed.
22367 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22368 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22369 (decode_coding_charset): Remove vars that are set but not used.
22371 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22372 that is set but not used.
22374 * print.c (print_object): Remove var that is set but not used.
22376 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22377 The gnulib version avoids calling malloc in the usual case,
22378 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22379 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22380 * filelock.c (current_lock_owner): Likewise.
22381 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22382 * sysdep.c: Include allocator.h, careadlinkat.h.
22383 (emacs_no_realloc_allocator): New static constant.
22384 (emacs_readlink): New function.
22385 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22386 ../lib/careadlinkat.h.
22388 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22390 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22391 first non-nil return value).
22393 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
22395 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
22396 if not defined (Bug#8403).
22398 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22400 * xdisp.c (display_count_lines): Remove parameter `start',
22401 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22402 (get_char_face_and_encoding): Remove parameter `multibyte_p',
22403 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

22405 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22406 and thereabouts. All callers changed.
22407 (get_per_char_metric): Remove parameter `f', unused since
22408 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
22410 2011-04-02 Jim Meyering <meyering@redhat.com>
22412 do not dereference NULL upon failed strdup
22413 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22414 (ns_get_family): Likewise.
22416 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22418 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
22420 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
22422 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
22425 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
22427 Add lexical binding.
22429 * window.c (Ftemp_output_buffer_show): New fun.
22430 (Fsave_window_excursion):
22431 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
22433 * lread.c (lisp_file_lexically_bound_p): New function.
22434 (Fload): Bind Qlexical_binding.
22435 (readevalloop): Remove `evalfun' arg.
22436 Bind Qinternal_interpreter_environment.
22437 (Feval_buffer): Bind Qlexical_binding.
22438 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
22440 (syms_of_lread): Declare `lexical-binding'.
22442 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22444 * keyboard.c (eval_dyn): New fun.
22445 (menu_item_eval_property): Use it.
22447 * image.c (parse_image_spec): Use Ffunctionp.
22449 * fns.c (concat, mapcar1): Accept byte-code-functions.
22451 * eval.c (Fsetq): Handle lexical vars.
22452 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22453 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22454 (FletX, Flet): Obey lexical binding.
22455 (Fcommandp): Handle closures.
22456 (Feval): New `lexical' arg.
22457 (eval_sub): New function extracted from Feval. Use it almost
22458 everywhere where Feval was used. Look up vars in lexical env.
22460 (Ffunctionp): Move from subr.el.
22461 (Ffuncall): Handle closures.
22462 (apply_lambda): Remove `eval_flags'.
22463 (funcall_lambda): Handle closures and new byte-code-functions.
22464 (Fspecial_variable_p): New function.
22465 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22466 but without exporting it to Lisp.
22468 * doc.c (Fdocumentation, store_function_docstring):
22469 * data.c (Finteractive_form): Handle closures.
22471 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22474 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22476 (exec_byte_code): New function extracted from Fbyte_code to handle new
22477 calling convention for byte-code-functions. Add new byte-codes.
22479 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22481 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22483 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22485 * xdisp.c (redisplay_internal): Fix prototype.
22487 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22489 * xdisp.c (SCROLL_LIMIT): New macro.
22490 (try_scrolling): Use it when setting scroll_limit.
22491 Limit scrolling to 100 screen lines.
22492 (redisplay_window): Even when falling back on "recentering",
22493 position point in the window according to scroll-conservatively,
22494 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22496 (try_scrolling): When point is above the window, allow searching
22497 as far as scroll_max, or one screenful, to compute vertical
22498 distance from PT to the scroll margin position. This prevents
22499 try_scrolling from unnecessarily failing when
22500 scroll-conservatively is set to a value slightly larger than the
22501 window height. Clean up the case of PT below the margin at bottom
22502 of window: scroll_max can no longer be INT_MAX. When aggressive
22503 scrolling is in use, don't let point enter the opposite scroll
22504 margin as result of the scroll.
22505 (syms_of_xdisp) <scroll-conservatively>: Document the
22506 threshold of 100 lines for never-recentering scrolling.
22508 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22510 * dispextern.h (move_it_by_lines):
22511 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
22512 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
22513 (message_log_check_duplicate): Remove parameters `prev_bol' and
22514 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22515 (redisplay_internal): Remove parameter `preserve_echo_area',
22516 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22518 * indent.c (Fvertical_motion):
22519 * window.c (window_scroll_pixel_based, Frecenter):
22520 Don't pass `need_y_p' to `move_it_by_lines'.
22522 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22524 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22525 steal a few bits to be more compact.
22526 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22527 Remove unneeded casts.
22529 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22531 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22533 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22534 binding" message (bug#7967).
22536 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22538 Fix more problems found by GCC 4.6.0's static checks.
22540 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22541 Remove unused local var.
22543 * editfns.c (Fmessage_box): Remove unused local var.
22545 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22546 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22547 Omit unused local vars.
22548 * window.c (shrink_windows): Omit unused local var.
22549 * menu.c (digest_single_submenu): Omit unused local var.
22550 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22551 Omit unused local var.
22553 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22554 Don't assume string length fits in int.
22555 (keyremap_step, read_key_sequence): Use size_t for sizes.
22556 (read_key_sequence): Don't check last_real_key_start redundantly.
22558 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22559 instead of alloca (Bug#8344).
22561 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22562 (Fbacktrace_frame): Don't assume nframes fits in int.
22564 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22566 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22569 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22571 * cm.c (calccost): Turn while-do into do-while, for clarity.
22573 * keyboard.c (syms_of_keyboard): Use the same style as later
22574 in this function when indexing through an array. This also
22575 works around GCC bug 48267.
22577 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22579 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22581 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22582 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22584 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22585 This avoids undefined behavior on integer overflow, and is a bit
22586 more convenient anyway since it is compared to a size_t variable.
22588 Variadic C functions now count arguments with size_t, not int.
22589 This avoids an unnecessary limitation on 64-bit machines, which
22590 caused (substring ...) to crash on large vectors (Bug#8344).
22591 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22592 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
22593 All variadic functions and their callers changed accordingly.

22599 (funcall_lambda, mark_backtrace): Likewise.
22600 * fns.c (concat): Likewise.
22601 * frame.c (x_set_frame_parameters): Likewise.
22602 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22603 0 if not found, not -1. All callers changed.
22605 * alloc.c (garbage_collect): Don't assume stack size fits in int.

22813 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22815 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22816 unconditionally since it does the check itself.
22818 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22820 Fix more problems found by GCC 4.5.2's static checks.
22822 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22823 the first time through the loop, since we know p0 < p1 then.
22824 This also avoids a gcc -Wstrict-overflow warning.
22826 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22827 leading to a memory leak, possible in functions like
22828 load_charset_map_from_file that can allocate an unbounded number
22829 of objects (Bug#8318).
22831 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22832 that could (at least in theory) be that large.
22834 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22835 This is less likely to overflow, and avoids undefined behavior if
22836 overflow does occur. All callers changed. Use strtoul to scan
22837 for the unsigned long integer.
22838 (pint2hrstr): Simplify and tune code slightly.

22854 * process.c (Fmake_network_process): Use socklen_t, not int,
22855 where POSIX says socklen_t is required in portable programs.
22856 This fixes a porting bug on hosts like 64-bit HP-UX, where
22857 socklen_t is wider than int (Bug#8277).
22858 (Fmake_network_process, server_accept_connection):
22859 (wait_reading_process_output, read_process_output):
22862 * process.c: Rename or move locals to avoid shadowing.

22872 Make tparam.h and terminfo.c consistent.
22873 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22874 Include tparam.h instead, since it declares them.
22875 * cm.h (PC): Remove extern decl; tparam.h now does this.
22876 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22877 * terminfo.c: Include tparam.h, to check interfaces.
22878 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22879 (tparam): Adjust signature to match interface in tparam.h;
22880 this removes some undefined behavior. Check that outstring and len
22881 are zero, which they always are with Emacs.
22882 * tparam.h (PC, BC, UP): New extern decls.
22884 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22885 (xftfont_open): Rename locals to avoid shadowing.

22903 (composition_update_it): Mark var as initialized.
22904 (find_automatic_composition): Mark vars as initialized,
22905 with a FIXME (Bug#8290).

22911 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22912 to avoid shadowing.

22924 Fix pointer signedness.
22925 (alsa_choose_format): Remove unused local var.
22926 (wav_play): Initialize a variable to 0, to prevent undefined
22927 behavior (Bug#8278).
22929 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
22931 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
22933 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
22934 clobbering (Bug#8298).
22935 * sysdep.c (sys_subshell): Likewise.
22936 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22938 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22939 This should get cleaned up, so that child_setup has the
22940 same signature on all platforms.
22942 * callproc.c (call_process_cleanup): Now static.
22943 (relocate_fd): Rename locals to avoid shadowing.
22945 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
22947 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
22948 not to be necessary, and produces flickering.
22950 2011-03-20 Glenn Morris <rgm@gnu.org>
22952 * config.in: Remove file.
22954 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

22999 Define only if needed.
23001 * unexelf.c (unexec): Name an expression,
23002 to avoid gcc -Wbad-function-cast warning.
23003 Use a different way to cause a compilation error if anyone uses
23004 n rather than nn, a way that does not involve shadowing.
23005 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
23007 * deps.mk (unexalpha.o): Remove; unused.

23061 to avoid gcc -Wbad-function-cast warning.
23062 (Fdefvar): Rename locals to avoid shadowing.
23064 * callint.c (quotify_arg, quotify_args): Now static.
23065 (Fcall_interactively): Rename locals to avoid shadowing.

23072 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
23073 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
23074 some of which prompt warnings from gcc -Wbad-function-cast.
23075 (Fformat_time_string, Fencode_time, Finsert_char):
23076 (Ftranslate_region_internal, Fformat):

23104 (Fmemory_limit): Cast sbrk's returned value to char *.
23106 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
23107 avoids undefined behavior in theory.
23109 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
23111 Use functions, not macros, for up- and down-casing (Bug#8254).
23112 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23113 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23114 to use the following functions instead of these macros.
23115 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23116 EMACS_INT, since callers assume the returned value fits in int.
23117 (upcase1): Likewise, for UPCASE_TABLE.
23118 (uppercasep, lowercasep, upcase): New static inline functions.
23119 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

23129 (regex_compile, re_match_2_internal): Mark locals as initialized.
23130 (RETALLOC_IF): Define only if needed.
23131 (WORDCHAR_P): Likewise. This one is never needed, but is used
23132 only in a comment talking about a compiler bug, so put inside
23133 the #if 0 of that comment.
23134 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23135 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

23161 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23162 New macros, so that the caller can use some names other than
23163 gcpro1, gcpro2, etc.
23164 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23166 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23167 argument, for consistency with GCPRO2_VAR, etc: it is now the
23168 prefix of the variable, not the variable itself. All uses
23170 * dired.c (directory_files_internal, file_name_completion):
23171 Rename locals to avoid shadowing.
23173 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23174 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23175 dired.c's scmp function, had undefined behavior.
23176 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23177 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23178 * buffer.h: ... to here, because these macros use current_buffer,
23179 and the new implementation with inline functions needs to have
23180 current_buffer in scope now, rather than later when the macros
23182 (downcase, upcase1): New static inline functions.
23183 (DOWNCASE, UPCASE1): Reimplement using these functions.
23184 This avoids undefined behavior in expressions like
23185 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23186 from race conditions in accessing the global variables
23187 case_temp1 and case_temp2.
23188 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23189 * lisp.h (case_temp1, case_temp2): Remove their decls.
23190 * character.h (ASCII_CHAR_P): Move from here ...
23191 * lisp.h: ... to here, so that the inline functions mentioned
23192 above can use them.
23194 * dired.c (directory_files_internal_unwind): Now static.
23196 * fileio.c (file_name_as_directory, directory_file_name):
23197 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
23199 (file_name_as_directory): Use const pointers when appropriate.
23200 (Fexpand_file_name): Likewise. In particular, newdir might
23201 point at constant storage, so make it a const pointer.
23202 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
23203 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23205 (Fset_file_times, Finsert_file_contents, auto_save_error):

23210 to avoid shadowing.
23212 * marker.c (bytepos_to_charpos): Remove; unused.
23214 * lisp.h (verify_bytepos, count_markers): New decls,
23215 so that gcc does not warn that these functions aren't declared.
23217 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
23218 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
23219 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
23220 (copy_text): Remove unused local var.
23222 * filelock.c (within_one_second): Now static.
23223 (lock_file_1): Rename local to avoid shadowing.
23225 * buffer.c (fix_overlays_before): Mark locals as initialized.
23226 (fix_start_end_in_overlays): Likewise. This function should be
23227 simplified by using pointers-to-pointers, but that's a different
23229 (switch_to_buffer_1): Now static.
23230 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
23231 (report_overlay_modification): Rename locals to avoid shadowing.

23234 Fix pointer signedness issue.
23235 (sys_subshell): Mark local as volatile if checking for lint,
23236 to suppress a gcc -Wclobbered warning that does not seem to be right.
23237 (MAXPATHLEN): Define only if needed.
23239 * process.c (serial_open, serial_configure): Move decls from here ...
23240 * systty.h: ... to here, so that they can be checked.
23242 * fns.c (get_random, seed_random): Move extern decls from here ...
23243 * lisp.h: ... to here, so that they can be checked.
23245 * sysdep.c (reset_io): Now static.

23254 (describe_map_tree):
23255 Rename locals to avoid shadowing.
23257 * keyboard.c: Declare functions static if they are not used elsewhere.

23404 For example, without this patch (encode-time 0 0 0 1 1
23405 1152921504606846976) returns the obviously-bogus value (-948597
23406 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
23407 reports time overflow. See
