368 * regex.c: Fix problems when DEBUG is defined.
369 (extract_number, extract_number_and_incr): Define regardless of
370 whether DEBUG is defined; that's simpler and makes the code less

372 Return int rather than taking an int * arg. All callers changed.
373 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
374 Remove, replacing with ...

384 Don't assume ptrdiff_t, size_t, and long are the same width as int.
385 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
386 This matters only when DEBUG is defined.
388 2013-05-05 Eli Zaretskii <eliz@gnu.org>
390 * xdisp.c (set_iterator_to_next): Set the
391 ignore_overlay_strings_at_pos_p flag only if we are _really_
392 iterating over an overlay string, as indicated by the
393 current.overlay_string_index member. (Bug#14306)
395 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
397 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
398 to where it is used, to avoid autorelease issues (Bug#14050).
400 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
402 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
403 * fileio.c (syms_of_fileio): Implement this.
404 * filelock.c (create_lock_file): If symbolic links don't work, so
405 we use a regular file as a lock file, do not fsync the lock file;
408 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>

480 window rectangle for the given fullscreen mode.
481 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no

486 window decorations and uses the entire screen.
488 * w32term.h (w32_fullscreen_rect) Add prototype.

519 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
520 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
521 Mention in the doc string that setting these variables takes
522 effect only after a call to set-window-buffer. (Bug#14200)
524 2013-04-13 Eli Zaretskii <eliz@gnu.org>
526 * indent.c (Fvertical_motion): Don't consider display strings on
527 overlay strings as display strings on the buffer position we
528 started from. This prevents vertical cursor motion from jumping
529 more than one line when there's an overlay string with a display
530 property at end of line.
531 Reported by Karl Chen <Karl.Chen@quarl.org> in
532 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

537 already selected (bug#14191).
539 2013-04-11 Eli Zaretskii <eliz@gnu.org>
541 * window.c (Fwindow_end): Test more flags, including the buffer's
542 last_overlay_modified flag, to determine whether the window's
543 display is really up-to-date. Prevents the function from
544 returning a stale value. (Bug#14170)
545 (Fwindow_line_height): Fix the test for up-to-date-ness of the
548 2013-04-10 Eli Zaretskii <eliz@gnu.org>
550 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
551 garbaged only if it is not already the top frame on its TTY.
552 This prevents flickering due to constant redrawing of TTY frames when
553 there are GUI frames open in the same session. (Bug#13864)
555 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
557 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead

589 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
590 This bug was introduced by my 2013-02-25 change that simplified
591 data_start configuration. Without this change, on GNU/Linux
592 an Emacs configured with --enable-profiling fails immediately
593 due to a profiler signal.
594 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
595 with these flags. On platforms where special flags are needed
596 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
597 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
598 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).

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

805 Use contents slot, not buffer, where appropriate.
806 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
807 to avoid deleted windows. Use contents slot instead of buffer.
808 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:

996 unless we are going to send SC_MAXIMIZE, to restore the frame
997 resize hints in the mouse pointer shown by the window manager.
1000 * frame.c (get_frame_param): Now extern for WINDOWSNT as well.

1207 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
1209 * xdisp.c (init_iterator): Simplify because both character and byte
1210 positions are either specified or -1. Add eassert. Adjust comment.
1211 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
1212 character and byte positions can be obtained from marker.

1231 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
1232 Include <sys/param.h> unconditionally, as that works elsewhere and
1233 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
1234 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
1237 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>

1439 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1441 Coding system support cleanup and minor refactoring.
1442 * coding.h (enum coding_result_code): Remove
1443 CODING_RESULT_INCONSISTENT_EOL and CODING_RESULT_INSUFFICIENT_MEM.
1444 (toplevel): Remove unused CODING_MODE_INHIBIT_INCONSISTENT_EOL.
1445 (CODING_MODE_LAST_BLOCK, CODING_MODE_SELECTIVE_DISPLAY)
1446 (CODING_MODE_DIRECTION, CODING_MODE_FIXED_DESTINATION)
1447 (CODING_MODE_SAFE_ENCODING): Rearrange bit values.
1448 (decode_coding_region, encode_coding_region, decode_coding_string):
1449 Remove unused compatibility macros.

1453 (ALLOC_CONVERSION_WORK_AREA): Use SAFE_ALLOCA.
1454 (decode_coding, encode_coding): Add USE_SAFE_ALLOCA and SAFE_FREE.
1455 (decode_coding_object): Simplify since xrealloc never returns NULL.
1458 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
1460 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1461 * sysdep.c (list_system_processes)
1462 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1463 Make it a stub in this case; otherwise the build might fail,
1464 and this code hasn't been tested on such hosts anyway.
1465 Problem reported by Nelson H. F. Beebe in
1466 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1467 and analyzed by Jérémie Courrèges-Anglas in
1468 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1470 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1472 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1473 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1474 (get_visually_first_element, move_it_vertically_backward): Ajust users.
1475 * bidi.c (bidi_find_paragraph_start): Likewise.
1476 * indent.c (vmotion): Likewise.
1478 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1480 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1481 * filelock.c: Include <c-ctype.h>.
1482 (MAX_LFINFO): New top-level constant.
1483 (lock_info_type): Remove members pid, boot_time. Add members at,
1484 dot, colon. Change user member to be the entire buffer, not a
1485 pointer. This allows us to handle the case where a foreign
1486 pid or boot time exceeds the local range. All uses changed.
1487 (LINKS_MIGHT_NOT_WORK): New constant.
1488 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1489 (defined_WINDOWSNT): Remove.
1490 (MAKE_LOCK_NAME, file_in_lock_file_name):
1491 Always use .#FILE (not .#-FILE) for the file lock,
1492 even if it is a regular file.
1493 (rename_lock_file): New function.
1494 (create_lock_file): Use it.
1495 (create_lock_file, read_lock_data):
1496 Prefer a symbolic link for the lock file, falling back on a
1497 regular file if symlinks don't work. Do not try to create
1498 symlinks on MS-Windows, due to security hassles. Stick with
1499 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1500 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1501 host may be using a Windowsish file system, and cannot use
1502 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1503 doesn't work. Don't fail merely because of a symlink-contents
1504 length limit in the current file system; fall back on regular
1505 files. Increase the symlink contents length limit to 8 KiB, this
1506 should be big enough for any real use and doesn't crunch the
1508 (create_lock_file, lock_file_1, read_lock_data):
1509 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1510 (lock_file_1): Return error number, not bool. All callers changed.
1511 (ELOOP): New macro, if not already defined.
1512 (read_lock_data): Return size of lock file contents, not Lisp object.
1513 All callers changed. Handle a race condition if some other process
1514 replaces a regular-file lock with a symlink lock or vice versa,
1515 while we're trying to read the lock.
1516 (current_lock_owner): Parse contents more carefully, to help avoid
1517 confusing a regular-file lock with some other application's use
1518 of the file. Check for lock file contents being too long, or
1519 not parsing correctly.
1520 (current_lock_owner, lock_file):
1521 Allow foreign pid and boot times that exceed the local range.
1522 (current_lock_owner, lock_if_free, lock_file):
1523 Simplify allocation of lock file contents.
1524 * w32.c (sys_rename_replace): New function, containing most of
1525 the contents of the old sys_rename.
1526 (sys_rename): Use it.
1527 (fchmod): New dummy function.
1528 * w32.h (sys_rename_replace, fchmod): New decls.
1530 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1532 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1533 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1534 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1535 <dmantipov@yandex.ru>.
1537 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1539 * composite.c (get_composition_id, fill_gstring_header):
1540 Use make_uninit_vector where appropriate.
1541 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1542 * xselect.c (clean_local_selection_data): Likewise.
1544 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1546 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1547 * image.c (imagemagick_load_image): Calculate height and width
1548 after flattening the image, not before.
1550 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1552 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1553 * ftfont.c (ftfont_shape_by_flt): Likewise.
1554 * w32uniscribe.c (uniscribe_shape): Likewise.
1556 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1558 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1559 The old approach, which fell back on DIR/.#FILE.0 through
1560 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1561 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1562 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1563 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1564 because the locking mechanism was never reliable in that case).
1565 This patch fixes this and other bugs discovered by a code
1566 inspection that was prompted by
1567 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1568 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1569 to avoid interoperability problems between the MS-Windows and
1570 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1571 instances of Emacs now ignore each others' locks.
1572 * filelock.c (defined_WINDOWSNT): New constant.
1573 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1574 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1575 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1576 regular files on MS-Windows hosts.
1577 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1578 Use SAFE_ALLOCA to avoid problems with long file names.
1579 (MAX_LFINFO): Now a local constant, not a global macro.
1580 (IS_LOCK_FILE): Remove.
1581 (lock_file_1): Don't inspect errno if symlink call succeeds;
1582 that's not portable.
1583 (lock_file): Document that this function can return if lock
1585 (lock_file): Don't access freed storage.
1587 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

1591 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1593 * textprop.c: Use bool for booleans.
1594 (validate_interval_range, Fadd_text_properties)
1595 (Fremove_text_properties): Prefer bool to int when either works.
1597 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1599 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1600 If the interval tree changes as a side effect of calling
1601 modify_region, re-do processing starting from the call to
1602 validate_interval_range. (Bug#13743)
1604 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1606 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1609 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1611 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1612 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1613 access to the lock file until it is written and closed.
1616 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1618 * callint.c (Qcall_interactively):
1619 * macros.c (Qexecute_kbd_macro):

1624 * window.c (Frecenter): Tiny docstring enhancement.
1626 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1628 Minor textprop integer cleanup.
1629 * intervals.h, textprop.c (add_text_properties_from_list):
1630 Return void, not int, since nobody uses the return value.
1631 * textprop.c (validate_plist, add_properties, remove_properties)
1632 (Fadd_text_properties):
1633 Don't assume list length fits in int.
1634 (interval_has_all_properties, interval_has_some_properties)
1635 (interval_has_some_properties_list, add_properties, remove_properties)
1636 (Fadd_text_properties, Fremove_text_properties)
1637 (Fremove_list_of_text_properties, text_property_stickiness):
1638 Use bool for booleans.
1639 (Fadd_text_properties, Fremove_text_properties):
1640 (Fremove_list_of_text_properties):
1641 Reindent do-while as per GNU style.

1645 Implement CLASH_DETECTION for MS-Windows.
1647 * filelock.c [WINDOWSNT]: Include w32.h.
1648 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1649 function of that name. Up-case the macro arguments.
1650 (IS_LOCK_FILE): New macro.
1651 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1652 (create_lock_file): New function, with body extracted from
1654 [WINDOWSNT]: Implement lock files by writing a regular file with
1655 the lock information as its contents.
1656 (read_lock_data): New function, on Posix platforms just calls
1658 [WINDOWSNT]: Read the lock info from the file.
1659 (current_lock_owner): Call read_lock_data instead of calling
1660 emacs_readlinkat directly.
1661 (lock_file) [WINDOWSNT]: Run the file name through
1664 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1665 just check if the process by that PID exists.
1667 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1668 also present, as doing so will fail to error out if the file
1671 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1673 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1674 (Fremove_list_of_text_properties): Skip all of the intervals in
1675 the region between START and END that already have resp. don't
1676 have the requested properties, not just the first one.
1677 Add assertions that the loop afterwards always modifies the
1678 properties. (Bug#13743)

1708 * vm-limit.c: Move most of mem-limits.h's contents here.
1709 (data_start): New decl. It's OK if this is approximate,
1710 so simplify-away some unnecessary exactness.
1711 (POINTER): Remove; all uses removed.
1712 (data_space_start): Now char *, to avoid casts.
1713 (exceeds_lisp_ptr): New function, replacing the old

1865 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1866 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1867 was #undeffed earlier, so it cannot be used as a macro here.
1868 Use the constant and not the macro.

1879 communications input, so that the status doesn't stay at
1880 STATUS_READ_IN_PROGRESS. (Bug#13546)
1882 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1884 * gtkutil.c (tb_size_cb): New function.
1885 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
1887 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1889 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
1892 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
1894 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1896 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
1898 * font.c (font_range): Add pos_byte argument. Adjust comment
1899 and break long line.
1900 * font.h (font_range): Adjust prototype.
1901 * composite.c (autocmp_chars): Pass byte position to font_range.
1902 Break long line. Remove useless prototype and format comment.
1904 2013-02-13 Glenn Morris <rgm@gnu.org>
1906 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1908 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1910 Improve AIX port some more (Bug#13650).
1911 With this, it should be as good as it was in 23.3, though it's
1912 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1913 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1914 * unexaix.c (start_of_text): Remove.
1915 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1916 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1917 (orig_load_scnptr, orig_data_scnptr):
1918 Now off_t, not long, since they are file offsets.
1919 (make_hdr): Use _data, not start_of_data ().
1920 This is the key part of the fix.
1921 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1922 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1924 * pre-crt0.c (data_start): Initialize to 1.
1925 This ports to compilers that optimize the external declaration
1926 'int x = 0;' as if it were 'int x;' to shrink the executable.
1928 Improve AIX port (Bug#13650).
1929 This doesn't fix the bug, but it makes progress: Emacs builds now.
1930 * unexaix.c: Include inttypes.h, stdarg.h.
1931 (report_error, report_error_1): Mark as _Noreturn.
1932 (report_error): Don't report the wrong errno.
1933 (report_error_1): Now varargs. All callers changed.
1934 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1935 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1936 (write_ptr): Use %p to print address rather than %lx and a cast
1937 to unsigned long. Grow buffer a bit, to be safer.
1939 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1941 * bidi.c (bidi_resolve_neutral): After finding the next
1942 non-neutral character, accept NEUTRAL_ON type as well, because
1943 directional control characters, such as LRE and RLE, have their
1944 type converted to that by bidi_resolve_weak. This avoids aborts
1945 when LRE/RLE follows a run of neutrals.
1946 (bidi_move_to_visually_next): Assert that return value of
1947 bidi_peek_at_next_level is non-negative. Negative values will
1950 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1952 Minor getenv-related fixes.
1953 * callproc.c (Fcall_process_region) [!DOS_NT]:
1954 Avoid unnecessary duplicate call to getenv.
1955 * callproc.c (init_callproc):
1956 * dispnew.c (init_display):
1957 * sysdep.c (sys_subshell):
1958 Omit unnecessary cast of getenv or egetenv.
1960 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1962 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1963 Update dependencies.
1965 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1967 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1969 (display_line): Set w->region_showing to the value of
1970 it->region_beg_charpos, not to -1. This fixes redisplay
1971 optimization when cursor is moved up after M->. (Bug#13623)
1973 (try_scrolling): Scroll text up more if point is too close to ZV
1974 and inside the scroll margin. This makes sure point is moved
1975 outside the scroll margin in these cases.
1977 * window.h (struct window): region_showing can no longer be
1980 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1982 Tune by using memchr and memrchr.
1983 * doc.c (Fsnarf_documentation):
1984 * fileio.c (Fsubstitute_in_file_name):
1985 * search.c (find_newline, scan_newline):
1986 * xdisp.c (pos_visible_p, display_count_lines):
1987 Use memchr and memrchr rather than scanning byte-by-byte.
1988 * search.c (find_newline): Rename from scan_buffer.
1989 Omit first arg TARGET, as it's always '\n'. All callers changed.
1991 Clean up read_key_sequence a tiny bit more.
1992 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1993 (read_key_sequence): Remove unused locals.
1995 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1997 Clean up read_key_sequence a bit; reread active keymaps after first event.
1998 * keyboard.c (read_char, read_char_x_menu_prompt)
1999 (read_char_minibuf_menu_prompt):
2000 Replace nmaps+maps with a single `map' arg.
2001 (follow_key): Operate on a single map.
2002 (active_maps): New function.
2003 (test_undefined): Also return true for nil bindings.
2004 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
2005 a single (composed) keymap. Remember `first_event' to choose the right
2006 set of active keymaps. Recompute the set of keymaps after receiving
2007 the first event. Remove GOBBLE_FIRST_EVENT.
2008 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
2009 * keyboard.h (read_char): Update declaration.
2010 * lread.c (read_filtered_event): Adjust call to read_char.
2012 2013-02-11 Eli Zaretskii <eliz@gnu.org>
2014 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2015 Don't use the limitation on backwards movement when lines are truncated
2016 in the window. (Bug#13675)
2018 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
2020 * marker.c (set_marker_internal): If desired position is passed
2021 as a marker, avoid call to buf_charpos_to_bytepos.
2022 * window.c (Fset_window_point): Omit redundant type checking.
2023 (Fset_window_start): Likewise. Format comment.
2024 (window_scroll_pixel_based): Use set_marker_restricted_both
2025 with character and byte positions obtained from an iterator.
2026 (Fset_window_configuration): Use set_marker_restricted_both.
2027 * xdisp.c (message_dolog): Likewise.
2029 2013-02-10 Eli Zaretskii <eliz@gnu.org>
2031 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2032 When text lines are longer than window's screen lines, don't move back
2033 too far. This speeds up some redisplay operations. (Bug#13675)
2035 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
2037 * syntax.c (scan_sexps_forward): Fix byte position calculation
2038 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
2040 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
2042 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
2043 that was not needed.
2045 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
2047 Minor hashing refactoring.
2048 * fns.c (SXHASH_REDUCE): Move to lisp.h.
2049 (sxhash_float): Return EMACS_UINT, for consistency with the other
2051 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
2052 non-static inline function and therefore can't use static vars.
2053 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
2054 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
2055 with the other hash functions.
2057 2013-02-09 Eli Zaretskii <eliz@gnu.org>
2059 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
2060 XXXXXX part of the temporary file pattern is not downcased even
2061 when w32-downcase-file-names is non-nil. (Bug#13661)
2063 * xdisp.c (decode_mode_spec): Remove handling of %t.
2065 * msdos.c (careadlinkatcwd): Remove.
2067 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
2069 * lread.c (skip_dyn_bytes): New function (bug#12598).
2070 (read1): Use it. Use getc instead of READCHAR to read bytes.
2071 (load_each_byte): Remove. Update users.
2073 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
2075 * search.c (scan_buffer): Calculate end byte position just once.

2079 (scan_sexps_forward): Record from_byte and avoid redundant
2080 character to byte position calculation ...
2081 (Fparse_partial_sexp): ... here. Break too long line.
2083 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
2085 * lisp.h (make_uninit_vector): New function.
2086 * alloc.c (Fvector, Fmake_byte_code):
2087 * ccl.c (Fregister_ccl_program):
2088 * charset.c (Fdefine_charset_internal, define_charset_internal):

2098 * window.c (Fcurrent_window_configuration):
2099 * xfaces.c (Fx_family_fonts):
2100 * xselect.c (selection_data_to_lisp_data): Use it.
2102 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
2104 * coding.c (Fdefine_coding_system_internal): Use AREF where
2105 argument is known to be a vector.
2106 * fns.c (Flocale_info): Likewise for ASET.
2107 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
2108 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
2110 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
2112 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
2115 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
2116 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
2117 updateCollectionBehaviour.
2119 * nsterm.m (NEW_STYLE_FS): Remove.
2120 (ns_last_use_native_fullscreen): New variable.
2121 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
2122 (x_set_window_size): Do not take title bar and tool bar into account
2123 if isFullscreen returns YES.
2124 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
2125 (check_native_fs): New function.
2126 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
2127 (ns_term_init): Remove NEW_STYLE_FS.
2128 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
2129 and tool bar if isFullscreen returns NO.
2130 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
2131 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
2132 with HAVE_NATIVE_FS.
2133 (window:willUseFullScreenPresentationOptions:): New method.
2134 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
2135 Hide toolbar if not enabled (Bug#13444).
2136 (windowDidExitFullScreen:): Call updateCollectionBehaviour.

2138 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
2139 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
2140 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
2141 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
2142 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
2143 (syms_of_nsterm): Add ns-use-native-fullscreen.
2145 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
2147 * fileio.c (Qchoose_write_coding_system): Now static.
2149 2013-02-04 Eli Zaretskii <eliz@gnu.org>
2151 * xdisp.c (window_buffer_changed): region_showing can be negative,
2152 which still means region is being displayed.
2153 (redisplay_internal): Resurrect code that forced redisplay of the
2154 whole window when showing region and the mark has changed.
2155 Record the new mark position to allow redisplay optimizations.
2156 (display_line): If it->region_beg_charpos is non-zero, set the
2157 window's region_showing member to -1. (Bug#13623) (Bug#13626)
2159 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
2160 not bitfield of 1 bit.
2162 2013-02-03 Daniel Colascione <dancol@dancol.org>
2164 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
2165 daemon mode works on cygw32 when Emacs is installed and not just
2168 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
2170 Avoid file time stamp bug on MS-Windows (Bug#13149).
2171 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
2172 as FAT32 doesn't update time stamps when truncating them.
2173 Also, check that a file time stamp is not a multiple of 100 ns;
2174 this should catch all instances of the problem on MS-Windows,
2175 as its native file system resolution is 100 ns or worse, and
2176 checking for a non-multiple of 100 ns should impose only a small
2177 overhead on systems with ns resolution.
2179 2013-02-02 Eli Zaretskii <eliz@gnu.org>
2181 Avoid encoding file names on MS-Windows when they need to be run
2182 through dostounix_filename.
2183 * w32.c (normalize_filename): Accept an additional argument
2184 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
2185 downcase it even if w32-downcase-file-names is non-nil.
2186 (dostounix_filename): Accept an additional argument MULTIBYTE and
2187 pass it to normalize_filename.
2188 (emacs_root_dir): Adjust.
2190 * msdos.h (dostounix_filename): Adjust prototype.
2192 * w32.h (dostounix_filename): Adjust prototype.
2194 * msdos.c (dostounix_filename): Accept an additional argument and
2196 (init_environment): Adjust callers of dostounix_filename.
2198 * fileio.c (Ffile_name_directory, file_name_as_directory)
2199 (directory_file_name, Fexpand_file_name)
2200 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
2202 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
2204 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
2205 variables, as egetenv is case-insensitive for DOS_NT.
2207 * dired.c (file_name_completion): Don't call Fdirectory_file_name
2208 with an encoded file name.
2210 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
2211 Adjust calls to dostounix_filename.
2213 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
2215 * unexw32.c (unexec): Adjust call to dostounix_filename.
2217 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
2219 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
2222 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
2225 * callproc.c (Fcall_process): Make sure program name in PATH and
2226 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
2227 is passed to exec/spawnve, which fails unless the file-name
2230 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
2231 even if w32-quote-process-args is nil.
2233 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2235 Fix timestamp bug when write-region appends nothing (Bug#13149).
2236 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
2237 the file's time stamp doesn't change if Emacs happens to write nothing
2238 to the file, and on a buggy file system this could cause Emacs to
2239 incorrectly infer that the file system doesn't have the bug.
2240 Avoid this problem by inhibiting the inference in this case.
2242 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
2244 * window.h (struct window): Convert base_line_number, base_line_pos
2245 and column_number_displayed members from Lisp_Object to ptrdiff_t.
2246 Convert region_showing member from Lisp_Object to bitfield.
2247 Remove sequence_number member. Adjust comments.
2248 * window.c (sequence_number): Remove.
2249 (make_window): Initialize column_number_displayed.
2250 * print.c (print_object): Follow the printed representation of
2251 frames and print window pointer to distinguish between windows.
2252 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
2253 * xdisp.c (wset_base_line_number, wset_base_line_pos)
2254 (wset_column_number_displayed, wset_region_showing): Remove.
2255 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
2256 (try_scrolling, try_cursor_movement, redisplay_window)
2257 (try_window_reusing_current_matrix, try_window_id, display_line)
2258 (display_mode_lines, decode_mode_spec): Adjust users.
2259 * .gdbinit (pwinx): Do not print sequence_number.
2261 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2263 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
2264 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
2265 * dired.c: Include <fcntl.h>.
2266 (open_directory): New function, which uses open and fdopendir
2267 rather than opendir. DOS_NT platforms still use opendir, though.
2268 (directory_files_internal, file_name_completion): Use it.
2269 (file_attributes): New function, with most of the old Ffile_attributes.
2270 (directory_files_internal, Ffile_attributes): Use it.
2271 (file_attributes, file_name_completion_stat): First arg is now fd,
2272 not dir name. All uses changed. Use fstatat rather than lstat +
2274 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
2275 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
2276 (emacs_readlinkat): New function, with much of the old
2277 Ffile_symlink_p, but with an fd argument for speed.
2278 It uses readlinkat rather than careadlinkatcwd, so that it
2279 need not assume the working directory.
2280 (Ffile_symlink_p): Use it.
2281 * filelock.c (current_lock_owner): Use emacs_readlinkat
2282 rather than emacs_readlink.
2283 * lisp.h (emacs_readlinkat): New decl.
2284 (READLINK_BUFSIZE, emacs_readlink): Remove.
2285 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2286 (emacs_norealloc_allocator, emacs_readlink): Remove.
2287 This stuff is moved to fileio.c.
2288 * w32.c (fstatat, readlinkat): New functions.
2289 (careadlinkat): Don't check that fd == AT_FDCWD.
2290 (careadlinkatcwd): Remove; no longer needed.
2292 2013-01-31 Glenn Morris <rgm@gnu.org>
2294 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
2295 (Fwrite_region): Update for new choose_write_coding_system args.
2296 Move the last piece of choose_write_coding_system here. (Bug#13522)
2297 (syms_of_fileio): Add choose-write-coding-system.
2299 2013-01-30 Eli Zaretskii <eliz@gnu.org>
2301 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2302 (sys_close): Zero out the flags for the file descriptor before
2303 closing it. (Bug#13546)
2305 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2306 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2307 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2310 * w32.c (w32_get_long_filename, init_environment, readlink):
2311 Support file names encoded in DBCS codepages.
2312 (readlink): Use the current file-name-coding-system, not the ANSI
2313 codepage, to decode and handle targets of symlinks.
2315 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2317 * w32.c (opendir): Now accepts a 'const char *'.
2319 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
2321 Remove obsolete redisplay code. See the discussion at
2322 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
2323 * dispnew.c (preemption_period, preemption_next_check): Remove.
2324 (Vredisplay_preemption_period): Likewise.
2325 (update_frame, update_single_window, update_window, update_frame_1):
2326 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2327 used, following the 2012-06-22 change.
2329 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2331 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2333 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
2335 * font.c (num_fonts): Remove the leftover from old
2336 debugging code. Adjust comment style here and there.

2341 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2343 * w32.c (max_filename_mbslen): New function.
2344 (normalize_filename, readdir): Use it to detect locales where ANSI
2345 encoding of file names uses a double-byte character set (DBCS).
2346 If a DBCS encoding is used, advance by characters using
2347 CharNextExA, instead of incrementing a 'char *' pointer.
2348 Use _mbslwr instead of _strlwr. (Bug#13515)
2350 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2351 request of memory reservation to 1.7GB. (Bug#13065)
2353 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
2355 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
2356 at check_extra_latin label. (Bug#13505)
2358 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2360 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
2361 Avoid redundant calls to strlen.
2363 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2365 Drop async_visible and async_iconified fields of struct frame.
2366 This is possible because async input is gone; for details, see
2367 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2368 * frame.h (struct frame): Remove async_visible and async_iconified
2369 members, convert garbaged to unsigned bitfield. Adjust comments.
2370 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2371 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2372 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2373 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2374 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2376 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2377 properly. Likewise for obscured.
2379 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
2382 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
2384 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2386 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
2387 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2389 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2391 * xdisp.c (message2, message2_nolog): Remove functions.
2392 (message3, message3_nolog): Extract nbytes and multibyteness directly
2393 from the string. Change all callers.
2394 (message3_nolog): Don't set message_enable_multibyte since set_message
2395 will reset it anyway.
2396 (message1, message1_nolog): Use message3.
2397 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2398 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2399 (set_message): Drop all but the second arg, which has to be a string.
2400 (set_message_1): Simplify now that we know that a1 is NULL and the
2401 second arg is a string.
2402 * frame.h (struct frame): Remove `message_buf' field.
2403 Use glyphs_initialized_p instead.
2404 (FRAME_MESSAGE_BUF): Remove macro.
2405 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
2406 * lisp.h (message2, message2_nolog): Remove declarations.
2407 (message3, message3_nolog): Update declarations.
2408 * keyboard.c (read_char_minibuf_menu_text)
2409 (read_char_minibuf_menu_width): Remove vars.
2410 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2411 to correctly handle multibyte strings.
2412 * frame.c (delete_frame): Don't free message_buf any more.
2413 * editfns.c (message_text, message_length): Remove vars.
2414 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2415 * fileio.c (auto_save_error): Use message3 instead of message2.
2416 * dispnew.c (adjust_frame_message_buffer): Remove function.
2418 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2420 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2421 real estate used for the tool bar and the menu bar.
2423 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2425 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2426 hidden buffer is prepared to modification (Bug#13164).
2428 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2430 * window.h (struct window): Change window_end_valid member from
2431 Lisp_Object to a bitfield. Adjust comments.
2432 (wset_window_end_valid): Remove.
2433 * window.c (adjust_window_count): Clear window_end_valid.
2434 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2435 (Fwindow_line_height, set_window_buffer, Frecenter)
2436 (Fsplit_window_internal, Fdelete_other_windows_internal)
2437 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2438 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2439 * xdisp.c (check_window_end, reconsider_clip_changes)
2440 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2441 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2442 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2444 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2446 * xdisp.c (mark_window_display_accurate): Simplify the loop
2447 assuming that the only one of vchild, hchild or buffer window
2448 slots is non-nil. Call mark_window_display_accurate_1 for
2449 the leaf windows only.
2450 (mark_window_display_accurate_1): Always assume leaf window.
2453 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2455 * emacs.c (Qkill_emacs_hook): Now static.
2457 * fileio.c (Finsert_file_contents): Simplify.
2458 Remove unnecessary assignments and tests.
2460 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2462 * w32.c (acl_set_file): Don't test for errors unless
2463 set_file_security returns FALSE. Avoids spurious errors when
2466 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2468 * fileio.c (Finsert_file_contents): Revert code introduced at
2469 2013-01-18 in favor of the simpler and generally better fix.
2470 Save stack space by removing 'buffer' and reusing 'read_buf'
2473 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2475 * lisp.h (eabs): Define unconditionally (Bug#13419).
2476 The old "#if !defined (eabs)" was an unnecessary revenant of back
2477 when this macro was called "abs". Document 'eabs' better.
2479 2013-01-19 Glenn Morris <rgm@gnu.org>
2481 * fns.c (Frandom): Doc fix.
2483 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2485 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2486 segfault when there are lots of overlays.
2488 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2489 when there are lots of overlays.
2490 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2491 for the details and a way to reproduce.
2493 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2495 * fileio.c: Use O_APPEND to append.
2496 This corresponds better to the natural interpretation of "append",
2497 and avoids the need to open the output file twice, or to invoke
2498 lseek when APPEND is neither nil nor a number.
2499 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2500 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2501 file possibly twice, and lseeking to its end; this avoids the
2502 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2503 at the same time: the combination is never needed and apparently
2504 it doesn't work with DOS_NT.
2506 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2507 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2509 Allow floating-point file offsets.
2510 Problem reported by Vitalie Spinu in
2511 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2512 * fileio.c (emacs_lseek): Remove.
2513 (file_offset): New function.
2514 (Finsert_file_contents, Fwrite_region): Use it.
2516 2013-01-19 Chong Yidong <cyd@gnu.org>
2518 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2519 aborting on Fsignal (Bug#13289).
2521 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2523 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2524 set_file_security as failure due to insufficient privileges.
2525 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2526 (fstat): Return owner and group like 'stat' and 'lstat' do.
2528 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2530 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2531 The bug was observed on Ubuntu operating inside a virtual machine,
2532 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2533 The workaround introduces a race condition on non-buggy hosts,
2534 but it's an unlikely race and anyway there's a nearly identical
2535 nearby race that can't be fixed.
2536 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2538 (Fwrite_region): Test for file system time stamp bug.
2539 (init_fileio): New function.
2540 * lisp.h (init_fileio): Declare it.
2541 * emacs.c (main): Call it.
2543 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2544 and make it more consistent with other stat-failure diagnostics.
2546 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2548 Fix crash when inserting data from non-regular files.
2549 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2550 for the error description produced by valgrind.
2551 * fileio.c (read_non_regular): Rename to read_contents.
2552 Free Lisp_Save_Value object used to pass parameters.
2553 (read_non_regular_quit): Rename to read_contents_quit.
2554 (Finsert_file_contents): Redesign internal file reading loop to adjust
2555 gap and end positions after each read and so help make_gap to work
2556 properly. Do not signal an I/O error too early and so do not leave
2557 not yet decoded characters in a buffer, which was the reason of
2558 redisplay crash. Use list2 to build return value. Adjust comments.
2560 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2562 Close a race when statting and reading files (Bug#13149).
2563 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2564 This avoids a race if the file is renamed between stat and open.
2565 This race is not the problem originally noted in Bug#13149;
2566 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2568 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

2574 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
2575 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2576 * alloc.c (format_save_value): Rename to make_save_value.
2577 (make_save_pointer): New function.
2578 (record_xmalloc): Use make_save_pointer.
2579 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2580 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2581 Change users of make_save_value to make_save_pointer.
2582 Likewise for format_save_value and make_save_value.

2593 * alloc.c (free_save_value): Now static.
2595 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2597 * keymap.c (map_keymap_internal): Use format_save_value.
2598 (map_keymap_char_table_item): Adjust accordingly.
2599 * fileio.c (non_regular_fd, non_regular_inserted)
2600 (non_regular_nbytes): Remove.
2601 (Finsert_file_contents): Convert trytry to ptrdiff_t.
2602 Use format_save_value to pass parameters to read_non_regular.
2603 (read_non_regular): Use XSAVE_ macros to extract parameters.
2605 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
2607 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
2609 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2611 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2612 extraction from any Lisp_Save_Value slot. Add type checking.
2613 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
2614 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
2615 * xselect.c: All users changed.
2617 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

2625 object with the specified internal structure.
2626 (make_save_value): Reimplement using format_save_value.
2627 * editfns.c (save_excursion_save): Use format_save_value.
2628 (save_excursion_restore): Use XSAVE_OBJECT.
2630 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
2632 Avoid needless casts with XSAVE_POINTER.
2633 * alloc.c (mark_object) [GC_MARK_STACK]:
2634 * dired.c (directory_files_internal_unwind):
2635 * fileio.c (do_auto_save_unwind):
2636 * gtkutil.c (pop_down_dialog):
2637 * keymap.c (map_keymap_char_table_item):
2638 * lread.c (load_unwind):
2639 * nsmenu.m (pop_down_menu):
2640 * print.c (print_object) [GC_MARK_STACK]:
2641 * xfns.c (clean_up_file_dialog):
2642 * xmenu.c (cleanup_widget_value_tree):
2643 Omit casts between XSAVE_POINTER and a pointer type.
2645 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2647 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
2648 * eval.c (eval_sub): Protect `form' from being GCed before its
2649 car and cdr becomes protected with the backtrace entry.
2651 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2653 Make Lisp_Save_Value more versatile storage for up to four objects.
2654 * lisp.h (toplevel): Enumeration to describe types of saved objects.
2655 (struct Lisp_Save_Value): New layout. Adjust comments.
2656 (XSAVE_POINTER): New macro.
2657 (XSAVE_INTEGER): Likewise.
2658 (allocate_misc): Add prototype.
2659 (free_misc): Likewise.
2660 * alloc.c (allocate_misc): Now global.
2661 (free_misc): Likewise. Adjust comment.
2662 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
2663 (free_save_value): Likewise.
2664 (mark_object): Likewise.
2665 * editfns.c (save_excursion_save): Pack everything within
2666 Lisp_Save_Value and so avoid xmalloc.
2667 (save_excursion_restore): Adjust to match new layout. Use free_misc
2668 because we do not allocate extra memory any more. Add eassert.
2669 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2670 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
2671 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
2672 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

2678 (nsfont_draw): Remove disabling of LCD smoothing.
2679 (ns_glyph_metrics): Add LCD_SMOOTHING_MARGIN to bearings to fix
2680 Bug#11484 with LCD smoothing on.
2682 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
2684 Fix SIGDANGER handlers, for AIX (Bug#13408).
2685 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
2686 Move handlers here from emacs.c; they were out of place.
2688 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
2690 * xterm.c (syms_of_xterm): Adjust documentation for
2691 scroll-bar-adjust-thumb-portion.
2693 2012-12-31 Adam Sjøgren <asjo@koldfront.dk> (tiny change)

2697 not. Use variable for MOTIF.
2699 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for
2702 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

2706 (doCommandBySelector:): Set processingCompose to NO.
2708 * nsfont.m (ns_findfonts): Add block/unblock_input calls.
2709 Remove check for fkeys count > zero, block/unblock fixes the real bug.
2710 (nsfont_list_family): Add block/unblock_input calls.
2711 (nsfont_open): Move block_input earlier. Add unblock_input before early
2713 (nsfont_draw): Add block/unblock_input calls.
2715 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
2717 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
2718 for old_charpos and old_bytepos.
2720 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>
2722 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
2723 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
2724 Clear tzvalbuf_in_environ if this workaround is in effect.
2725 Problem and fix reported by Kazuhiro Ito.
2727 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>
2729 * insdel.c (Fcombine_after_change_execute, syms_of_insdel):

2733 doc string cross-reference(s).
2735 * window.c (Fwindow_point, syms_of_window): Fix ambiguous doc
2736 string cross-reference(s).
2738 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
2740 Avoid unnecessary byte position calculation for the gap movement.
2741 Since all users of move_gap do CHAR_TO_BYTE for other purposes
2742 anyway, all of them should use move_gap_both instead.
2743 * lisp.h (move_gap): Remove prototype.
2744 * insdel.c (move_gap): Remove.
2745 (move_gap_both): Add eassert.
2746 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.
2747 * xml.c (parse_region): Likewise.
2749 2013-01-11 Paul Eggert <eggert@cs.ucla.edu>
2751 emacsclient -t should not suspend Emacs server (Bug#13387)
2752 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
2754 * term.c (init_tty): Use them instead of rolling our own code.
2755 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
2756 switches from 'signal' to 'pthread_sigmask', which is safer in
2757 multithreaded applications.
2758 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
2759 which has already arranged for that.
2760 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
2761 This is the main part of the bug fix.
2763 2013-01-10 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)
2765 * gtkutil.c (xg_initialize): Add ifdef HAVE_FREETYPE around
2766 x_last_font_name (Bug#13403).
2768 2013-01-10 Dmitry Antipov <dmantipov@yandex.ru>
2770 Omit buffer_slot_type_mismatch and use generic predicates to enforce
2771 the type of per-buffer values where appropriate.
2772 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
2773 predicate, which is how it's really used now. Adjust comment.
2774 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
2775 * buffer.c (buffer_slot_type_mismatch): Remove.
2776 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

2905 (xg_update_submenu): Skip tearoff only if
2906 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2907 (xg_initialize): Initialize xg_detached_menus only if
2908 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2910 * xterm.h (struct x_output): Surround handlebox_widget with

2937 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2939 Port EXTERNALLY_VISIBLE to Clang 3.2.
2940 * conf_post.h (__has_attribute): New macro.
2941 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2943 2012-12-27 Glenn Morris <rgm@gnu.org>
2945 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2946 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2948 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2950 * fileio.c (file_name_as_directory, directory_file_name):
2951 Accept an additional argument MULTIBYTE to indicate whether the input C
2952 came from a multibyte or a unibyte Lisp string; all callers
2953 adjusted. Don't assume the input string is always multibyte.
2955 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2956 don't ENCODE_FILE them, and return a unibyte string if the input
2958 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2959 don't assume the input strings will always be multibyte. If the
2960 input strings are multibyte, decode strings obtained from C
2963 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2965 * lisp.h (toplevel): Add two notices to the comment about

2974 * keyboard.c (record_asynch_buffer_change): Initialize an event
2975 only if it's really needed.
2976 * frame.h (enum output_method): Remove output_mac member since
2977 it's a leftover from the deleted code.
2978 * frame.c (Fframep): Adjust user here ...
2979 * terminal.c (Fterminal_live_p): ... and here.
2980 * coding.c (Qmac): Now here because it's only used to denote
2981 end-of-line encoding type.
2982 (syms_of_coding): DEFSYM it.
2983 * frame.h (Qmac): Remove duplicated declaration.
2985 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2987 * window.c (select_window_1): Now static, since it's used only here.

2991 * window.c (window_body_cols): Subtract display margins from the
2992 window body width on TTYs as well. See
2993 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2994 for the original report.
2996 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2998 * xdisp.c (redisplay_window): Remove inner local variable
2999 because the outer shadowed one has the same meaning.
3000 * xterm.h (struct x_output): Remove toolbar_detached member since it's
3002 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
3003 (xg_create_tool_bar): Adjust users.
3005 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
3007 * buffer.h (BUF_COMPACT): New macro to follow the common style.
3008 * buffer.c (Fget_buffer_create): Use it to set compact field of
3009 struct buffer_text to avoid accessing an uninitialized value
3010 when compact_buffer is called for the first time.
3011 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
3012 (Fset_buffer_modified_p): Use buffer_window_count to check
3013 whether the buffer is displayed in some window.
3014 * xdisp.c (message_dolog): Likewise.
3016 2012-12-23 Eli Zaretskii <eliz@gnu.org>
3018 * w32.c (acl_set_file): If setting the file security descriptor
3019 fails, and the new DACL is identical to the existing one, silently
3020 return success. This fixes problems for users backing up their
3021 own files without having the necessary privileges for setting
3022 security descriptors.
3024 * w32proc.c (reader_thread): Do not index fd_info[] with negative
3026 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
3027 after WaitForSingleObject returns normally. This expedites reader
3028 thread shutdown when delete_child triggers it.
3029 (reap_subprocess): More accurate commentary for why we call
3030 delete_child only when cp->fd is negative.
3032 * w32.c (sys_close): Do not call delete_child on a subprocess
3033 whose handle is not yet closed. Instead, set its file descriptor
3034 to a negative value, so that reap_subprocess will call
3035 delete_child on that subprocess when its SIGCHLD arrives.
3036 This avoids closing handles used for communications between sys_select
3037 and reader_thread, which doesn't give sys_select a chance to
3038 notice that the process exited and invoke the SIGCHLD handler for
3041 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
3043 * nsfns.m (Fns_do_applescript): Run event loop until script has
3044 been executed (Bug#12969).

3052 2012-12-22 Eli Zaretskii <eliz@gnu.org>
3054 * w32term.c (w32fullscreen_hook): New function.
3055 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
3057 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3059 * fileio.c (Finsert_file_contents): Doc fix.
3061 * w32proc.c (new_child, delete_child, find_child_pid): For a
3062 subprocess, consider its slot being in use as long as its process
3063 handle (procinfo.hProcess) is not NULL. This avoids reusing the
3064 slot when a new process is started immediately after killing
3065 another one, without waiting enough time for the first process to
3066 be reaped and resources allocated for it be orderly freed.
3068 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
3070 2012-12-21 Chong Yidong <cyd@gnu.org>
3072 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
3074 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
3076 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3078 * w32.c (get_name_and_id): Always pass NULL as the first argument
3079 of lookup_account_sid. Avoids crashes with UNC file names that
3080 refer to DFS domains, not to specific machine names. (Bug#12621)
3081 Remove now unused argument FNAME; all callers changed.
3082 (get_file_owner_and_group): Remove now unused argument FNAME; all
3085 2012-12-21 Chong Yidong <cyd@gnu.org>
3087 * editfns.c (Finsert_char): Since read-char-by-name now signals an
3088 error for invalid chars, don't check for a nil return value.
3090 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3092 Avoid calls to CHAR_TO_BYTE if byte position is known.
3093 * editfns.c (make_buffer_string_both): Use move_gap_both.

3099 * fileio.c (Finsert_file_contents): Use move_gap_both.
3100 * search.c (Freplace_match): Likewise.
3101 * process.c (process_send_region): Likewise. Use convenient
3102 names for byte positions.
3103 * lisp.h (charpos_to_bytepos): Remove prototype.
3104 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
3105 * insdel.c (move_gap): Likewise.

3113 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
3114 (redisplay_internal): Don't bother selecting the frame to get the
3115 proper value of frame-local variables (bug#13225).
3117 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3119 * textprop.c (set_text_properties_1): Do not allow NULL interval.
3120 Rename 4th argument since it may be buffer or string. Adjust comment.
3121 * intervals.c (graft_intervals_info_buffer): Find an interval here.
3123 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
3125 * coding.c (Fdetect_coding_region): Do not check start and end with
3126 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
3127 (code_convert_region): Likewise.
3129 2012-12-18 Eli Zaretskii <eliz@gnu.org>
3131 * w32.c (acl_get_file, acl_set_file): Run the file name through
3132 map_w32_filename, and resolve any symlinks in the file name, like

3140 ($(BLD)/w32.$(O)): Update dependencies.
3142 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
3144 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
3145 propagate redisplay's scrolling (if any) to the right window.
3146 (redisplay_internal): Use ensure_selected_frame.
3147 (display_mode_lines): Complete last fix.
3148 * window.c (select_window_1): New func, extracted from select_window.
3149 (select_window): Use it.

3178 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
3179 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
3180 for some of that bug's symptoms can now cause Emacs to abort.
3181 Remove the workaround.
3182 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
3183 The bug that caused SIGCHLD to get lost has been fixed, and the
3184 workaround for it can now cause Emacs to abort.
3186 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
3188 * sysdep.c (emacs_abort): Bump backtrace size to 40.
3189 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
3190 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

3257 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3259 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
3260 try to get accurate owner and group information from NT file
3261 security APIs. This is to make most callers of 'stat' and
3262 'lstat', which don't need that information, much faster.
3264 * dired.c (Ffile_attributes) [WINDOWSNT]:
3265 Set w32_stat_get_owner_group to a non-zero value, to request accurate
3266 owner and group information from 'lstat'.
3268 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3270 * fileio.c (Finsert_file_contents): Don't put tail into head area,
3271 as that confuses set-auto-coding, so insist on the head-read
3272 returning the full 1024 bytes. Let lseek compute the tail offset;
3273 less work for us. Do not ignore I/O errors when reading the tail.
3275 * xdisp.c: Minor style fixes.
3276 (init_iterator): Hoist assignment out of if-expression.
3277 (markpos_of_region): Callers now test for sign, not for -1.

3296 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
3297 files, fixing a regression from 24.2.

3300 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3302 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
3303 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3304 Remove unnecessary S_ISLNK test, as (contra the comments) this
3305 function can't copy symlinks. Improve quality of error message
3306 when attempting to copy files that are neither regular files nor

3315 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
3317 2012-12-12 Daniel Colascione <dancol@dancol.org>
3319 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
3320 the dumped Emacs is not a sparse file, greatly improving Cygwin
3321 "make bootstrap" performance.
3323 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
3325 * inotify.c (inotify_callback): Generate an Emacs event for every
3326 incoming inotify event.
3328 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3330 * xdisp.c (handle_face_prop): Fix logic of computing
3331 it->start_of_box_run_p.

3333 iterator's end_of_box_run_p flag before prepending the space glyph.
3334 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
3335 iterator's start_of_box_run_p flag before prepending the stretch.
3336 (append_glyph, produce_image_glyph, append_composite_glyph)
3337 (append_stretch_glyph, append_glyphless_glyph): Reverse the
3338 left_box_line_p and right_box_line_p flags of the glyph for R2L
3339 glyph rows. (Bug#13011)

3346 * window.c (replace_buffer_in_windows_safely): Do nothing
3347 if buffer is not shown in a window.

3351 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3353 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
3354 encoded_file_name, which is what it is.
3356 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
3358 Consistently use marker_position and marker_byte_position.
3359 * fringe.c (Ffringe_bitmaps_at_pos):

3382 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
3385 * w32fns.c (cache_system_info): Initialize the global hinst
3386 variable here so various initialization calls DTRT.
3388 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
3389 (hinst): Remove unneeded extern declaration.
3390 (_start): Remove initialization of above variables; remove
3391 initialization of hinst, as cache_system_info now does that.

3397 Teach the autoconf build system how to compile a Windows resource file
3398 and link it to Emacs.

3535 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3537 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
3538 * alloc.c (xputenv): New function.
3539 * dbusbind.c (Fdbus_init_bus):
3541 * xterm.c (x_term_init):
3542 Use xputenv instead of setenv or putenv, to detect memory exhaustion.

3552 no longer needed here.
3553 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
3554 Move to inside set_time_zone_rule; they don't need file scope any more.
3555 (set_time_zone_rule): Maintain the TZ=value string separately.
3556 (syms_of_editfns): Don't initialize initial_tz;
3557 init_editfns now does it.

3578 Remove USG and vlimit methods; no longer used these days.
3579 Add #error catchall just in case.
3581 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3582 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,

3610 * frame.c (make_frame): Do not set window's buffer to t.
3611 * window.c (Fsplit_window_internal): Likewise. Previously it was
3612 used to indicate that the window is being set up. Now we use
3613 set_window_buffer for all new windows, so the condition in ...
3614 (Fset_window_buffer): ... is always true and can be removed.
3616 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3618 Convenient macro to check whether the buffer is hidden.
3619 * buffer.h (BUFFER_HIDDEN_P): New macro.

3628 loop and return zero. (Bug#13086)
3630 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3632 * frame.h (x_char_width, x_char_height): Remove prototypes.

3645 Fix a recently-introduced delete-process race condition.
3646 * callproc.c, process.h (record_kill_process):
3647 New function, containing part of the old call_process_kill.
3648 (call_process_kill): Use it.
3649 This does not change call_process_kill's behavior.
3650 * process.c (Fdelete_process): Use record_kill_process to fix a
3651 race condition that could cause Emacs to lose track of a child.
3653 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3655 Avoid code duplication between prev_frame and next_frame.
3656 * frame.c (candidate_frame): New function. Add comment.
3657 (prev_frame, next_frame): Use it. Adjust comment.
3659 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3661 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3662 fails, signal an error instead of continuing with an empty
3664 Encode expanded temp file pattern before passing it to mkstemp or
3667 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3668 Encode the file name before passing it to dostounix_filename, in
3669 case it will downcase it (under w32-downcase-file-names).
3672 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3674 Minor call-process cleanups.
3675 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3676 at the same time as other platforms, to simplify analysis.
3677 No need for fd0_volatile since we have synch_process_fd.
3678 Avoid needless emacs_close; arg is always negative.
3680 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3682 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3685 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3687 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3688 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer

3695 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3696 members to a bitfields.
3698 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3700 Don't let call-process be a zombie factory (Bug#12980).
3701 Fixing this bug required some cleanup of the signal-handling code.
3702 As a side effect, this change also fixes a longstanding rare race
3703 condition whereby Emacs could mistakenly kill unrelated processes,
3704 and it fixes a bug where a second C-g does not kill a recalcitrant
3705 synchronous process in GNU/Linux and similar platforms.
3706 The patch should also fix the last vestiges of Bug#9488,
3707 a bug which has mostly been fixed on the trunk by other changes.
3708 * callproc.c, process.h (synch_process_alive, synch_process_death)
3709 (synch_process_termsig, sync_process_retcode):
3710 Remove. All uses removed, to simplify analysis and so that
3711 less consing is done inside critical sections.
3712 * callproc.c (call_process_exited): Remove. All uses replaced
3713 with !synch_process_pid.
3714 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3715 These take the role of what used to be in unwind-protect arg.
3717 (block_child_signal, unblock_child_signal):
3718 New functions, to avoid races that could kill innocent-victim processes.
3719 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3720 (call_process_kill): Record killed processes as deleted, so that
3721 zombies do not clutter up the system. Do this inside a critical
3722 section, to avoid a race that would allow the clutter.
3723 (call_process_cleanup): Fix code so that the second C-g works again
3724 on common platforms such as GNU/Linux.
3725 (Fcall_process): Create the child process in a critical section,
3726 to fix a race condition. If creating an asynchronous process,
3727 record it as deleted so that zombies do not clutter up the system.
3728 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3729 light of these changes. Omit unnecessary call to emacs_close
3730 before failure, as the unwind-protect code does that.
3731 * callproc.c (call_process_cleanup):
3732 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3733 * process.c (record_deleted_pid): New function, containing
3734 code refactored out of Fdelete_process.
3735 (Fdelete_process): Use it.
3736 (process_status_retrieved): Remove. All callers changed to use
3737 child_status_change.
3738 (record_child_status_change): Remove, folding its contents into ...
3739 (handle_child_signal): ... this signal handler. Now, this
3740 function is purely a handler for SIGCHLD, and is not called after
3741 a synchronous waitpid returns; the synchronous code is moved to
3742 wait_for_termination. There is no need to worry about reaping
3743 more than one child now.
3744 * sysdep.c (get_child_status, child_status_changed): New functions.
3745 (wait_for_termination): Now takes int * status and bool
3746 interruptible arguments, too. Do not record child status change;
3747 that's now the caller's responsibility. All callers changed.
3748 Reimplement in terms of get_child_status.
3749 (wait_for_termination_1, interruptible_wait_for_termination):
3750 Remove. All callers changed to use wait_for_termination.
3751 * syswait.h: Include <stdbool.h>, for bool.
3752 (record_child_status_change, interruptible_wait_for_termination):
3754 (record_deleted_pid, child_status_changed): New decls.
3755 (wait_for_termination): Adjust to API changes noted above.
3757 * bytecode.c, lisp.h (Qbytecode): Remove.
3758 No longer needed after 2012-11-20 interactive-p changes.
3760 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3762 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3763 the scroll margin, move point outside the margin. (Bug#13055)

3772 * lisp.h (modify_region): Rename to...
3773 (modify_region_1): ...new prototype.
3774 * textprop.c (modify_region): Now static. Adjust users.
3775 * insdel.c (modify_region): Rename to...
3776 (modify_region_1): ...new function to work with current buffer.
3777 Adjust comment and users. Use true and false for booleans.
3779 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3781 * alloc.c (free_save_value): New function.
3782 (safe_alloca_unwind): Use it.
3783 * lisp.h (free_save_value): New prototype.
3784 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3786 (save_excursion_restore): Adjust to match saved data structure.
3787 Use free_save_value to offload some work from GC. Drop obsolete
3790 2012-12-03 Chong Yidong <cyd@gnu.org>
3792 * fileio.c (Vauto_save_list_file_name): Doc fix.
3794 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3796 * w32fns.c: Remove prototype of atof.
3797 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3799 (file_dialog_callback): Make it UINT_PTR.
3801 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3804 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3805 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3808 2012-12-03 Glenn Morris <rgm@gnu.org>
3810 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3812 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3814 Fix xpalloc confusion after memory is exhausted.
3815 * alloc.c (xpalloc): Comment fix.
3816 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3817 and signals an error, do not clear charset_table_size, as
3818 charset_table is still valid.
3819 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3821 Use execve to avoid need to munge environ (Bug#13054).
3822 * callproc.c (Fcall_process):
3823 * process.c (create_process):
3824 Don't save and restore environ; no longer needed.
3825 * callproc.c (child_setup):
3826 Use execve, not execvp, to preserve environ.
3828 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3830 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3832 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3834 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3835 display for sliced images (Bug#10500).
3837 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3839 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3841 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3842 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3844 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3846 * xdisp.c (window_outdated): Remove eassert since it hits
3847 some suspicious corner cases (see Bug#13007 and Bug#13012).
3848 (mode_line_update_needed): New function.
3849 (redisplay_internal, redisplay_window): Use it.
3850 (ensure_selected_frame): New function.
3851 (redisplay_internal, unwind_redisplay): Use it.
3852 (redisplay_internal): Move comment about buffer_shared...
3853 (buffer_shared_and_changed): ...near to its real use.
3855 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3857 * callproc.c (Fcall_process): Don't misreport vfork failure.
3859 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3861 * callproc.c (Fcall_process): Fix vfork portability problems.
3862 Do not assume that fd[0], count, filefd, and save_environ survive
3863 vfork. Fix bug whereby wrong errno value could be reported for
3864 pipe failure. Some minor cleanups, too, as follows. Move buf and
3865 bufsize to the context where they're needed. Change new_argv to
3866 be of type char **, as this is more convenient and avoids casts.
3867 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3868 Now local constants, not macros.
3870 2012-11-18 Kenichi Handa <handa@gnu.org>
3872 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3873 for the variable "f".

3877 * font.c (font_unparse_xlfd): Exclude special characters from the
3878 generating XLFD name.

3896 * unexcoff.c (write_segment): Assume EFAULT is defined.
3898 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3900 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
3903 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
3904 highlighting on the frame was cleared. Prevents assertion
3905 violations when repeatedly clicking on the "Top" link of the
3906 "bread-crumbs" in Info buffers.
3908 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>

3916 were always defined.
3918 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3920 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3921 between bpos_covered and bpos_max. This fixes cursor display when
3922 several display strings follow each other.
3924 * .gdbinit (pgx): If the glyph's object is a string, display the
3925 pointer to string data, rather than the value of the string object
3926 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3928 * indent.c (Fvertical_motion): If the starting position is covered
3929 by a display string, return to one position before that, to avoid
3930 overshooting it inside move_it_to. (Bug#12930)
3932 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3934 * frame.h (struct frame): Remove display_preempted member

3937 * w32menu.c (pending_menu_activation): Remove since not
3939 (set_frame_menubar): Adjust user.
3940 * w32term.h (struct x_output): Drop outdated #if 0 code.

3943 Drop unused pending_menu_activation member.
3944 * xterm.h (struct x_output): Drop outdated #if 0 code.
3945 Use bitfields for explicit_parent, asked_for_visible,
3946 has_been_visible and net_wm_state_hidden_seen members.
3948 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3950 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3951 of a literal "/". (Bug#12955)
3952 (gl-stamp): Invoke fc.exe directly, not through cmd.
3954 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
3956 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
3957 * dired.c: Assume HAVE_DIRENT_H.
3958 (NAMLEN): Remove, replacing with ...
3959 (dirent_namelen): New function. All uses changed. Use the GNU macro
3960 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3961 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3962 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3963 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3965 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3966 * ndir.h: Rename to ../nt/inc/dirent.h.
3967 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3968 Do not include <dirent.h>; no longer needed.
3969 * w32.c: Include <dirent.h> rather than "ndir.h".
3971 2012-11-23 Chong Yidong <cyd@gnu.org>
3973 * xftfont.c (xftfont_open): Remove duplicate assignment.
3975 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3977 * alloc.c (Fgarbage_collect): Unblock input after clearing
3978 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3979 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3980 * msdos.c (IT_frame_up_to_date): Use it here...
3981 * w32term.c (w32_frame_up_to_date): ...here...
3982 * xterm.c (XTframe_up_to_date): ...and here...
3983 * nsterm.m (ns_frame_up_to_date): ...but not here.
3984 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3986 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3987 Do not check whether GC is in progress.
3989 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3991 * xdisp.c (window_buffer_changed): New function.
3992 (update_menu_bar, update_tool_bar): Use it to
3993 simplify large 'if' statements.
3994 (redisplay_internal): Generalize commonly used
3995 'tail' and 'frame' local variables.
3997 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3999 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
4000 with Windows system header.
4002 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
4004 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
4005 * alloc.c: Assume unistd.h exists.

4009 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
4010 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
4011 * w32.h (getcwd): Remove decl.
4013 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
4015 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
4016 Make it set selected_window as well.

4019 2012-11-21 Ken Brown <kbrown@cornell.edu>
4021 * emacs.c (main): Set the G_SLICE environment variable for all
4022 Cygwin builds, not just GTK builds. See
4023 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
4025 2012-11-21 Eli Zaretskii <eliz@gnu.org>
4027 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4028 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
4029 Define for the MSVC compiler.
4031 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
4033 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
4034 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
4035 dostounix_filename. Prevents crashes down the road, because
4036 dostounix_filename assumes it gets a unibyte string.
4037 Reported by Michel de Ruiter <michel@sentient.nl>, see

4069 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
4070 (syms_of_eval): Remove corresponding defsubr.
4071 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
4073 2012-11-19 Daniel Colascione <dancol@dancol.org>
4075 * w32fns.c (Fx_file_dialog):
4076 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
4077 cygwin_convert_file_name*.
4079 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
4080 Rename cygwin_convert_path* to cygwin_convert_file_name*.
4082 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
4084 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
4086 2012-11-18 Eli Zaretskii <eliz@gnu.org>
4088 * w32select.c: Include w32common.h before w32term.h, so that
4089 windows.h gets included before w32term.h uses some of its
4090 features, see below.
4092 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
4094 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

4098 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
4100 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
4101 (ns_select): Return at once if events are held (Bug#12834).
4103 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
4105 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
4106 Needed following 2012-10-20 change. (Bug#12902)
4108 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
4110 * w32proc.c (waitpid): Remove unused label get_result.
4112 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
4114 * makefile.w32-in (SYSWAIT_H): New macro.
4115 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
4116 ($(BLD)/sysdep.$(O)): Update dependencies.

4121 * callproc.c (relocate_fd): Assume F_DUPFD.
4122 * emacs.c, term.c (O_RDWR): Remove.
4123 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
4124 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
4125 * nsterm.m: Assume <fcntl.h> exists.
4126 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
4127 (create_pty, Fmake_network_process, server_accept_connection)
4128 (wait_reading_process_output, init_process_emacs):
4130 (wait_reading_process_output): Put in a special case for WINDOWSNT
4131 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
4132 It's not clear this is needed, but it's a more-conservative change.
4133 (create_process): Assume FD_CLOEXEC.
4134 (create_process, create_pty): Assume O_NOCTTY.
4135 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
4136 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
4137 Omit if not DOS_NT, since F_GETFL is not defined there.
4138 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
4139 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
4141 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
4142 lack it, since gnulib guarantees this.
4143 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
4145 2012-11-17 Eli Zaretskii <eliz@gnu.org>
4147 * w32.c (faccessat): Pretend that directories have the execute bit
4148 set. Emacs expects that, e.g., in files.el:cd-absolute.
4150 * w32proc.c (create_child): Don't clip the PID of the child
4151 process to fit into an Emacs integer, as this is no longer a
4153 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
4154 reaping only the process specified by PID argument, if that is
4155 positive. Use PID instead of dead_child to know which process to
4156 reap. Wait for the child to die only if WNOHANG is not in
4158 (sys_select): Don't set dead_child.
4160 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
4161 as it is no longer needed.
4163 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
4165 (record_child_status_change): Remove the setting of
4166 record_at_most_one_child for the !WNOHANG case.
4168 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4170 Fix problems in ns port found by static checking.
4171 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
4172 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
4173 not to process group.
4174 (ns_select): Use emacs_write, not write, as that's more robust
4175 in the presence of signals.
4176 (fd_handler:): Check for read errors.
4178 2012-11-16 Glenn Morris <rgm@gnu.org>
4180 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
4182 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
4184 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
4186 2012-11-16 Eli Zaretskii <eliz@gnu.org>
4188 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
4189 use the same value of thread handle.
4190 (start_timer_thread): If the timer thread exited (due to error),
4191 clean up by closing the two handles it used. Duplicate the caller
4192 thread's handle here, so it gets duplicated only once, when
4193 launching the timer thread. Set priority of the timer thread, not
4195 (getitimer): Don't duplicate the caller thread's handle here.
4198 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
4200 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
4203 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
4205 Remove no-longer-used pty_max_bytes variable.
4206 * process.c (pty_max_bytes): Remove; unused.
4207 (send_process): Do not set it.
4209 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
4211 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
4212 Update dependencies.
4214 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
4216 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
4217 This follows up on the 2012-09-29 patch that removed indirection
4218 for the 'function' field. Reported by Sergey Vinokurov in
4219 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
4221 2012-11-14 Eli Zaretskii <eliz@gnu.org>
4223 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
4224 different name, as the MS runtime does not have such a function,
4225 and probably never will.) All callers changed. Ignore DIRFD
4226 value if PATH is an absolute file name, to match Posix spec
4227 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
4230 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
4232 * xdisp.c (echo_area_display, redisplay_internal):
4233 Omit redundant check whether frame_garbaged is set.
4235 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
4237 Use faccessat, not access, when checking file permissions (Bug#12632).
4238 This fixes a bug that has been present in Emacs since its creation.
4239 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
4240 which must set some sort of record. (Torek's bug report was against
4241 a predecessor of GNU Emacs, but GNU Emacs happened to have the
4242 same common flaw.) See Torek's Usenet posting
4243 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
4244 Posted: Fri Apr 8 14:18:56 1983.
4245 * Makefile.in (LIB_EACCESS): New macro.
4247 * callproc.c (init_callproc):
4248 * charset.c (init_charset):
4249 * fileio.c (check_existing, check_executable, check_writable)
4251 * lread.c (openp, load_path_check):
4252 * process.c (allocate_pty):
4254 Use effective UID when checking permissions, not real UID.
4255 * callproc.c (init_callproc):
4256 * charset.c (init_charset):
4257 * lread.c (load_path_check, init_lread):
4258 Test whether directories are accessible, not merely whether they exist.
4259 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
4260 * fileio.c (check_existing, check_executable, check_writable)
4262 Use symbolic names instead of integers for the flags, as they're
4264 (check_writable): New arg AMODE. All uses changed.
4265 Set errno on failure.
4266 (Ffile_readable_p): Use faccessat, not stat + open + close.
4267 (Ffile_writable_p): No need to call check_existing + check_writable.
4268 Just call check_writable and then look at errno. This saves a syscall.
4269 dir should never be nil; replace an unnecessary runtime check
4270 with an eassert. When checking the parent directory of a nonexistent
4271 file, check that the directory is searchable as well as writable, as
4272 we can't create files in unsearchable directories.
4273 (file_directory_p): New function, which uses 'stat' on most platforms
4274 but faccessat with D_OK (for efficiency) if WINDOWSNT.
4275 (Ffile_directory_p, Fset_file_times): Use it.
4276 (file_accessible_directory_p): New function, which uses a single
4277 syscall for efficiency.
4278 (Ffile_accessible_directory_p): Use it.
4279 * xrdb.c (file_p): Use file_directory_p.
4280 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
4281 * lread.c (openp): When opening a file, use fstat rather than
4282 stat, as that avoids a permissions race. When not opening a file,
4283 use file_directory_p rather than stat.
4284 (dir_warning): First arg is now a usage string, not a format.
4285 Use errno. All uses changed.
4286 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4287 that merely introduced a race.
4288 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4289 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4290 and similarly for the other O_* flags.
4291 * w32.c (sys_faccessat): Rename from sys_access and switch to
4292 faccessat's API. All uses changed.
4293 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4294 (magic_db): Rename from magic_file_p.
4295 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4296 char *, so that we don't have to test for file existence
4297 separately from opening the file for reading. This removes a race
4298 fixes a permission-checking problem, and simplifies the code.
4300 (file_p): Remove; no longer needed.
4302 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4304 Omit glyphs initialization at startup.
4305 * dispnew.c (glyphs_initialized_initially_p): Remove.
4306 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4307 (Fredraw_frame): Move actual code from here...
4308 (redraw_frame): ...to here. Add eassert. Adjust comment.
4309 (Fredraw_display): Use redraw_frame.
4310 * xdisp.c (clear_garbaged_frames): Likewise.
4312 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4314 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4315 passed to pint2str and pint2hrstr to be at most the size of the
4316 frame's decode_mode_spec_buffer. This avoids crashes with very
4317 large values of FIELD_WIDTH argument to decode_mode_spec.
4320 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4322 Fix a race with verify-visited-file-modtime (Bug#12863).
4323 Since at least 1991 Emacs has ignored an mtime difference of no
4324 more than one second, but my guess is that this was to work around
4325 file system bugs that were fixed long ago. Since the race is
4326 causing problems now, let's remove that code.
4327 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4328 whose time stamp is off by no more than a second. Insist that the
4329 file time stamps match exactly.
4331 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4333 * frame.h (struct frame): Convert external_tool_bar member to
4334 1-bit unsigned bitfield.
4335 * termhooks.h (struct terminal): Remove mouse_moved member since
4336 all users are long dead. Adjust comment on mouse_position_hook.
4338 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4340 Simplify by using FOR_EACH_FRAME here and there.
4341 * frame.c (next_frame, prev_frame, other_visible_frames)
4342 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4343 * w32term.c (x_window_to_scroll_bar): Likewise.
4344 * window.c (window_list): Likewise.
4345 * xdisp.c (x_consider_frame_title): Likewise.
4346 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
4347 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4348 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4349 * xmenu.c (menubar_id_to_frame): Likewise.
4350 * xselect.c (frame_for_x_selection): Likewise.
4351 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4352 (x_window_to_menu_bar): Likewise.
4353 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4355 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4357 * data.c (Qdefalias_fset_function): Now static.
4359 Another tweak to vectorlike_header change.
4360 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4361 Remove, and replace all uses with ...
4362 (next_in_free_list, set_next_in_free_list):
4363 New functions, which respect C's aliasing rules better.
4365 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4367 * window.c (list4i): Rename from 'quad'. All uses changed.
4368 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4370 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4372 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4373 warning about mixing declarations and code in ISO C90.
4375 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4377 * window.c (Fsplit_window_internal): Set combination limit of
4378 new parent window to t iff Vwindow_combination_limit is t;
4379 fixing a regression introduced with the change from 2012-09-22.
4380 (Fset_window_combination_limit): Fix doc-string.
4382 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4384 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4385 amount when the scroll margins are too large. When scrolling
4386 backwards in the buffer, give up if cannot reach point or the
4387 scroll margin within a reasonable number of screen lines.
4388 Fixes point position in window under scroll-up/down-aggressively when
4389 point is positioned many lines beyond the window top/bottom.
4392 * ralloc.c (relinquish): If real_morecore fails to return memory
4393 to the system, don't crash; instead, leave the last heap
4394 unchanged and return. (Bug#12774)
4396 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4398 * lisp.h (AUTOLOADP): New macro.
4399 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
4400 * data.c (Ffset): Remove special ad-advice-info handling.
4401 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
4403 (Finteractive_form): Simplify.
4404 (Fquo): Don't insist on having at least 2 arguments.
4405 (Qdefalias_fset_function): New var.
4407 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4409 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
4411 * nsfont.m (Qcondensed, Qexpanded): New variables.
4412 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
4413 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
4415 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4417 Fix recently introduced crash on MS-Windows (Bug#12839).
4418 * w32term.h (struct scroll_bar): Use convenient header.
4419 (SCROLL_BAR_VEC_SIZE): Remove.
4420 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4422 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4424 Tweak last vectorlike_header change.
4425 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4426 vectorlike object on the free list. This is introduced to avoid
4427 some (but not all) pointer casting and aliasing problems, see
4428 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4429 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
4431 (xvectype, xvecsize): Use them to examine Lisp_Object values.
4433 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4435 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4436 been removed, so remove them here also.
4438 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4440 * doc.c (Fdocumentation): Handle new property
4441 dynamic-docstring-function to replace the old ad-advice-info.
4443 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4445 * fns.c (Qeql, hashtest_eq): Now static.
4447 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4449 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4450 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4451 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
4452 * buffer.c (compare_overlays): Use XLI rather than XHASH.
4454 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
4456 Use same hash function for hashfn_profiler as for hash_string etc.
4457 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
4458 * lisp.h (sxhash_combine): New inline function, with the contents
4459 of the old SXHASH_COMBINE.
4460 * profiler.c (hashfn_profiler): Use it, instead of having a
4461 special hash function containing a comparison that always yields 1.
4463 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4465 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4466 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4467 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4470 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4472 * image.c (xpm_make_color_table_h): Fix compiler error because
4473 make_hash_table changed.
4475 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4477 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4479 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4481 Use ad-hoc comparison function for the profiler's hash-tables.
4482 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4483 (make_log): Use them.
4484 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4485 call Fequal any more.
4486 (Ffunction_equal): New function.
4487 (cmpfn_profiler, hashfn_profiler): New functions.

4494 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4495 (hash_lookup, hash_remove_from_table): Move assertion checking of
4496 hashfn result here. Check hash-equality before calling cmpfn.

4503 * print.c (print_object): Adjust to new hash-table struct.
4504 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
4506 2012-11-08 Eli Zaretskii <eliz@gnu.org>
4508 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4509 value of w32-scroll-lock-modifier is neither nil nor one of the
4510 known key modifiers. (Bug#12806)
4512 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4514 Shrink struct vectorlike_header to the only size field.
4515 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4517 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4518 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4519 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4520 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4521 information from the vector header. Adjust comment.
4522 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
4523 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
4525 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.

4529 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
4530 (sweep_string, lisp_malloc): Remove useless prototypes.
4531 (enum mem_type): Adjust comment.
4532 (NEXT_IN_FREE_LIST): New macro.
4533 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
4534 (Fmake_bool_vector): Likewise.
4535 (struct large_vector): New type to represent allocation unit for
4536 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4537 (large_vectors): Change type to struct large_vector.
4538 (allocate_vector_from_block): Simplify.
4539 (PSEUDOVECTOR_NBYTES): Replace with...
4540 (vector_nbytes): ...new function. Adjust users.
4541 (sweep_vectors): Adjust processing of large vectors.
4542 (allocate_vectorlike): Likewise.
4543 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4544 Add easserts. Adjust XSETPVECTYPESIZE usage.
4545 (allocate_buffer): Use BUFFER_PVEC_INIT.
4546 (live_vector_p): Adjust to match large vector.
4547 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4548 * buffer.h (struct buffer): Add next member.
4549 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4551 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
4552 * fns.c (internal_equal): Adjust to match enum pvec_type change.
4553 (copy_hash_table): Adjust to match vector header change.
4554 * lread.c (defsubr): Use XSETPVECTYPE.
4555 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
4556 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
4557 (xvecsize): New command.
4559 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4561 * keyboard.c (event_to_kboard): Do not dereference
4562 frame_or_window field of SELECTION_REQUEST_EVENT
4563 and SELECTION_CLEAR_EVENT events (Bug#12814).
4564 * xterm.h (struct selection_input_event): Adjust comment.
4566 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4568 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4569 such as Scroll Lock, if the respective keys are treated as
4570 function keys, not as modifiers. This avoids destroying non-ASCII
4571 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4573 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4575 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4577 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4579 Restore some duplicate definitions (Bug#12814).
4580 This undoes part of the 2012-11-03 changes. Some people build
4581 with plain -g rather than with -g3, and they need the duplicate
4582 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4583 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4584 Define as macros, as well as as enums or as constants.
4586 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4588 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4589 to keypad keys (Bug#12816).
4591 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4593 Minor adjustments of recently-changed frame functions.
4594 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4595 known to be a frame (we're in the FRAMEP branch).
4596 * lisp.h (Qframep): Remove decl. frame.h declares this.
4597 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4598 since they're meant for Lisp fixnum values.
4600 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4602 * window.c (Fwindow_combination_limit): Revert to the only
4603 required argument and adjust docstring as suggested in
4604 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4605 by Martin Rudalics <rudalics@gmx.at>.
4607 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4609 Widely used frame validity and checking functions.
4610 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
4611 * frame.c (decode_live_frame, decode_any_frame): New functions.
4612 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
4613 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
4614 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
4615 (Fframe_pointer_visible_p): Use decode_any_frame.
4616 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
4617 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
4618 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
4619 (Fframe_focus): Likewise. Allow zero number of arguments.
4621 (frame_buffer_list, frame_buffer_predicate): Remove.
4622 * lisp.h (frame_buffer_predicate): Remove prototype.
4623 * buffer.c (Fother_buffer): Use decode_any_frame.
4624 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4625 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4626 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4627 (Fclose_font, Ffont_info): Use decode_live_frame.
4628 * fontset.c (check_fontset_name): Likewise.
4629 * terminal.c (Fframe_terminal): Likewise.
4630 * w32fns.c (check_x_frame): Likewise.
4631 * window.c (Fminibuffer_window, Fwindow_at)
4632 (Fcurrent_window_configuration): Likewise.
4633 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
4634 Likewise. Allow zero number of arguments. Adjust docstring.
4635 * dispnew.c (Fredraw_frame): Likewise.
4636 * xfaces.c (frame_or_selected_frame): Remove.
4637 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4638 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4639 (Fframe_face_alist): Use decode_live_frame.
4640 * xfns.c (check_x_frame): Likewise.
4642 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4644 * window.c (quad): New function.
4645 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4646 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4647 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4648 (Fwindow_line_height): Use it.
4649 (Fwindow_fringes): Use list3.
4650 (Fwindow_scroll_bars): Use list4.
4651 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4652 (Fwindow_combination_limit): Allow zero number of arguments.
4654 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4656 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4658 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4659 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4660 file descriptor 2 for standard error. (Bug#12805)
4662 2012-11-05 Chong Yidong <cyd@gnu.org>
4664 * process.c (wait_reading_process_output): Revert previous change.
4666 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4668 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4669 This removes code that has been obsolete since around 1990.
4670 * callproc.c (Fcall_process):
4672 * process.c (create_process):
4673 * term.c (dissociate_if_controlling_tty):
4674 Assume setsid exists.
4675 * callproc.c (child_setup): Assume setpgid exists and behaves as
4676 per POSIX.1-1988 or later.
4677 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4678 * emacs.c (shut_down_emacs):
4679 * sysdep.c (sys_suspend, init_foreground_group):
4680 Assume getpgrp behaves as per POSIX.1-1998 or later.
4681 * msdos.c (setpgrp): Remove.
4682 (tcgetpgrp, setpgid, setsid): New functions.
4683 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4684 * term.c (no_controlling_tty): Remove; unused.
4685 * w32proc.c (setpgrp): Remove.
4686 (setsid, tcgetpgrp): New functions.
4688 Simplify by assuming __fpending.
4689 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4690 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4691 Do not assume that __fpending's result fits in int.
4693 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4695 Remove EMACS_OUTQSIZE+sleep hack.
4696 * dispnew.c (update_frame_1): Remove hack for terminals slower
4697 than 2400 bps, which throttled Emacs by having it sleep.
4698 This code hasn't worked since at least 2007, when the multi-tty stuff
4699 was added, and anyway those old terminals are long dead.
4700 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4701 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4703 Fix data-loss with --version (Bug#9574).
4704 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4705 as we can't assume that emacs_strerror is initialized, and strerror
4706 is good enough here.
4707 (main): Invoke atexit earlier, to catch earlier instances of
4708 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4710 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4712 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4713 (keyDown): Remap keypad keys to X11 virtual key codes.
4715 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4717 Fix data-loss with --batch (Bug#9574).
4718 * emacs.c: Include <close-stream.h>.
4719 (close_output_streams): New function.
4720 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4721 and handles errors appropriately.
4722 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4725 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4726 The symptom is a diagnostic "GLib-WARNING **: In call to
4727 g_spawn_sync(), exit status of a child process was requested but
4728 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4729 waitpid(), so exit status can't be returned." The diagnostic
4730 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4731 The real bug is a race condition between Emacs and glib: Emacs
4732 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4733 so that glib can't find it. Work around the bug by invoking
4734 waitpid only on subprocesses that Emacs itself creates.
4735 * process.c (create_process, record_child_status_change):
4736 Don't use special value -1 in pid field, as the caller now must
4737 know the pid rather than having the callee infer it.
4738 The inference was sometimes incorrect anyway, due to another race.
4739 (create_process): Set new 'alive' member if child is created.
4740 (process_status_retrieved): New function.
4741 (record_child_status_change): Use it.
4742 Accept negative 1st argument, which means to wait for the
4743 processes that Emacs already knows about. Move special-case code
4744 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4745 processes that have already been waited for, by testing and
4746 clearing new 'alive' member.
4747 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4748 now does this internally.
4749 (handle_child_signal): Let record_child_status_change do all
4750 the work, since we do not want to reap all exited child processes,
4751 only the child processes that Emacs itself created.
4752 * process.h (Lisp_Process): New boolean member 'alive'.
4754 Omit duplicate definitions no longer needed with gcc -g3.
4755 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4756 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4757 Define only as macros. There's no longer any need to also define
4758 these symbols as enums or as constants, since we now assume
4759 gcc -g3 when debugging.
4761 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4763 * lisp.mk: Adjust comments to the fact that term/internal is now
4764 loaded from loadup.el.
4766 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4767 (msdos_fatal_signal): New function.
4768 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4771 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4772 for GCC versions before 4.
4773 (emacs_raise): Define to call msdos_fatal_signal.
4775 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4776 iterator when starting in the middle of a display or overlay
4779 2012-11-03 Chong Yidong <cyd@gnu.org>
4781 * process.c (wait_reading_process_output): Clean up the last
4784 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4786 * process.c (wait_reading_process_output): Avoid a race condition
4787 with SIGIO delivery (Bug#11536).
4789 2012-11-03 Chong Yidong <cyd@gnu.org>
4791 * buffer.c (cursor_type): Untabify docstring.
4793 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4795 * frame.h (struct frame): Drop can_have_scroll_bars member
4796 which is meaningless for a long time. Adjust comments.
4797 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4798 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4800 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4802 * window.c (decode_next_window_args): Update window arg after
4803 calling decode_live_window and so fix crash reported at
4804 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4805 by Juanma Barranquero <lekktu@gmail.com>.
4806 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4807 * font.c (Ffont_at): Likewise.
4809 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4811 * widget.c (resize_cb): New function.
4812 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4813 (EmacsFrameResize): Check if all is up to date before changing frame
4816 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4818 Implement backtrace output for fatal errors on MS-Windows.
4819 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4820 (BACKTRACE_LIMIT_MAX): New macro.
4821 (w32_backtrace): New function.
4822 (emacs_abort): Use w32_backtrace when the user chooses not to
4823 attach a debugger. Update the text of the abort dialog.
4825 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4827 Window-related stuff cleanup here and there.
4828 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4829 Use decode_any_window.
4830 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4831 * xdisp.c (Fformat_mode_line): Likewise.
4832 * font.c (Ffont_at): Use decode_live_window.
4833 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4834 * window.c (decode_next_window_args): Likewise.
4835 (decode_any_window): Remove static.
4836 * window.h (decode_any_window): Add prototype.
4837 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4838 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4841 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4843 Remove pad from struct input_event.
4844 * termhooks.h (struct input_event): Remove padding field.
4846 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4847 member is never cons for a long time. Adjust comment.
4848 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4849 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4850 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4851 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4853 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4855 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4857 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4859 Fix crash when using Emacs as commit editor for git (Bug#12697).
4860 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4861 and it is configured in conf_post.h.
4862 (Fcall_process): Don't invoke both setsid and setpgid; the former
4863 is enough, if it exists.
4864 * callproc.c (Fcall_process, child_setup):
4865 * process.c (create_process): Use setpgid.
4866 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4868 * dispnew.c (init_display): Initialize the foreground group
4869 if we are running a tty display.
4870 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4871 * lisp.h (init_foreground_group): New decl.
4872 * sysdep.c (inherited_pgroup): New static var.
4873 (init_foreground_group, tcsetpgrp_without_stopping)
4874 (narrow_foreground_group, widen_foreground_group): New functions.
4875 (init_sys_modes): Narrow foreground group.
4876 (reset_sys_modes): Widen foreground group.
4878 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4880 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4882 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4884 * minibuf.c (read_minibuf): Restore current buffer since
4885 choose_minibuf_frame calling Fset_frame_selected_window may
4886 change it (Bug#12766).
4888 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4890 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4892 2012-10-30 Kenichi Handa <handa@gnu.org>
4894 * font.c (Ffont_at): If WINDOW is specified and it is not
4895 displaying the current buffer, signal an error.
4897 2012-10-29 Daniel Colascione <dancol@dancol.org>
4899 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4900 In preparation for fixing bug#12739, move these functions from
4903 * coding.h, coding.c: ... to here, and compile them only when
4904 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4905 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4907 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4909 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4910 (timer_loop, getitimer, setitimer): Use it instead of
4911 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4913 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4916 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4918 * nsterm.m (NO_APPDEFINED_DATA): New define.
4919 (last_appdefined_event_data): New variable
4920 (last_appdefined_event): Remove.
4921 (ns_select): Initialize t from last_appdefined_event_data instead
4922 of [last_appdefined_event data1].
4923 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4924 remove last_appdefined_event (Bug#12698).
4926 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4928 * frame.c (x_set_font): Catch internal error.
4930 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4932 Avoid overflow in w32 implementation of interval timers.
4933 When possible, for ITIMER_PROF count only times the main thread
4935 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4936 'volatile ULONGLONG' types. All the other data which was
4937 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4938 (GetThreadTimes_Proc): New typedef.
4939 (w32_get_timer_time): New function, returns a suitable time value
4941 (timer_loop): Enter critical section when accessing ULONGLONG
4942 values of the itimer_data struct, as these accesses are no longer
4943 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4944 Remove unused variable.
4945 (init_timers): Initialize s_pfn_Get_Thread_Times.
4946 (start_timer_thread): Don't assign itimer->caller_thread here.
4947 (getitimer): Assign itimer->caller_thread here.
4948 (setitimer): Always call getitimer to get the value of ticks_now.
4949 (sys_spawnve): Avoid compiler warning about format mismatch.
4951 2012-10-26 Eli Zaretskii <eliz@gnu.org>
4953 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4954 mouse movement events if the menu bar is active. This avoids
4955 producing a busy "hour-glass" cursor by Windows if the mouse
4956 pointer is positioned over a tooltip shown for some menu item.
4958 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4960 Don't assume process IDs fit in int.
4961 * emacs.c (shut_down_emacs) [!DOS_NT]:
4962 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4963 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4964 Use pid_t, not int, to store process IDs, as 'int'
4965 is not wide enough on a few platforms (e.g., AIX and IRIX).
4967 2012-10-23 Kenichi Handa <handa@gnu.org>
4969 The following change is to make face-font-rescale-alist work
4970 correctly for non-ASCII fonts.
4972 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4973 (font_open_for_lface): Handle Vface_font_rescale_alist.
4975 2012-10-23 Chong Yidong <cyd@gnu.org>
4977 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4979 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
4981 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
4983 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
4985 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
4988 2012-10-21 Glenn Morris <rgm@gnu.org>
4990 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4992 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4994 Port to OpenBSD 5.1.
4995 * frame.c (Fmouse_position, Fmouse_pixel_position):
4996 * xdisp.c (produce_stretch_glyph):
4997 Declare local vars only when they're needed.
4998 This is clearer and avoids a warning on OpenBSD about unused vars.
4999 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
5000 This is safer, and avoids OpenBSD warnings about unused vars.
5001 * keyboard.c (record_menu_key): Remove unnecessary decl.
5002 (poll_timer): Define only if POLL_FOR_INPUT is defined.
5003 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
5004 as our definition clashes with OpenBSD's.
5005 * xfaces.c (load_face_colors, check_lface_attrs)
5006 (get_lface_attributes_no_remap, get_lface_attributes)
5007 (lface_fully_specified_p, x_supports_face_attributes_p)
5008 (tty_supports_face_attributes_p, face_fontset, realize_face)
5009 (realize_x_face, realize_tty_face):
5010 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
5011 merely Lisp_Object *. This is more informative and avoids
5012 a warning on OpenBSD about accessing beyond an object's size.
5014 2012-10-20 Chong Yidong <cyd@gnu.org>
5016 * lread.c (Fload): Doc fix (Bug#12592).
5018 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
5020 * font.c (Ffont_at): Fix previous change.
5022 2012-10-19 Eli Zaretskii <eliz@gnu.org>
5024 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
5025 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
5028 * alloc.c (NSTATICS): Decrease to 0x800.
5030 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
5032 * fns.c (Fnreverse): Include the problem element when signaling an
5035 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
5037 * nsterm.m (ns_select): Check writefds before call to
5038 FD_ISSET (Bug#12668).
5040 2012-10-18 Daniel Colascione <dancol@dancol.org>
5042 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
5043 (staticpro): If we run out of staticpro slots, die with an
5044 informative error instead of just calling emacs_abort.
5046 2012-10-18 Martin Rudalics <rudalics@gmx.at>
5048 Fix two flaws reported by Dmitry Antipov.
5049 * window.c (Ftemp_output_buffer_show): Remove.
5050 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
5051 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
5053 2012-10-17 Eli Zaretskii <eliz@gnu.org>
5055 * makefile.w32-in ($(BLD)/w32.$(O)):
5056 ($(BLD)/vm-limit.$(O)):
5058 ($(BLD)/unexw32.$(O)):
5059 ($(BLD)/fileio.$(O)):
5060 ($(BLD)/dispnew.$(O)): Update dependencies.
5062 * w32term.h (w32_initialize_display_info, initialize_w32_display):
5065 * w32proc.c: Include ctype.h.
5067 * w32.h (init_environment, check_windows_init_file)
5068 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
5069 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
5070 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
5071 (sys_link): Add prototypes.
5073 * w32.c: Include w32select.h.
5074 (sys_access, e_malloc, sys_select): Add prototypes.
5075 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.

5202 * fileio.c (check_existing): New function.
5203 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
5204 instead of calling 'stat', when what's needed is to check whether
5205 a file exists. This avoids expensive system calls on MS-Windows.
5208 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.

5301 * process.c (wait_reading_process_output):
5302 Use unsigned for counter where wraparound-on-overflow is desired,
5303 since unsigned is guaranteed to have that behavior and signed is not.
5304 (read_char): Use ptrdiff_t for string length.
5305 (get_input_pending): Remove first argument, since it was always
5306 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5307 and behave as if it had that value. Return new value of
5308 input_pending. All callers changed.
5309 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5310 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
5312 * keymap.c (push_key_description): Omit last arg, which was always 1.
5313 All callers changed.
5315 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
5317 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

5333 Don't include termopts.h.
5335 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
5337 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
5339 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5341 * commands.h (immediate_quit): Remove duplicate decl.
5343 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
5345 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

5350 2012-10-09 Eli Zaretskii <eliz@gnu.org>
5352 * w32fns.c (w32_last_error): Change the return value to DWORD, to
5353 match what GetLastError returns. Explain why the function is
5356 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5357 'is_tooltip_frame', to avoid confusion with its global namesake.
5359 2012-10-08 Daniel Colascione <dancol@dancol.org>
5361 * xdisp.c (start_hourglass): Call w32_note_current_window when
5362 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5363 build that caused Emacs to display the hourglass cursor forever.
5365 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5366 which is broken under remote desktop, calculate the number of
5367 colors available for a display based on the display's number of
5368 planes and number of bits per pixel per plane. (bug#10397).
5370 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5372 * nsfont.m (Vfonts_in_cache): New variable.
5373 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5374 are used. Add cached fonts to Vfonts_in_cache.
5375 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5377 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5379 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5381 (FONT_H): Define after FRAME_H.
5382 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5383 Update dependencies.
5385 * w32term.c: Remove leftover declaration of keyboard_codepage.
5387 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5389 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5390 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5391 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5392 (GLOBAL_SOURCES): Add cygw32.c.
5393 ($(BLD)/unexw32.$(O)):
5395 ($(BLD)/w32console.$(O)):
5396 ($(BLD)/w32fns.$(O)):
5397 ($(BLD)/w32heap.$(O)):
5398 ($(BLD)/w32menu.$(O)):
5399 ($(BLD)/w32proc.$(O)): Add w32common.h.
5401 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5403 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5405 2012-10-08 Daniel Colascione <dancol@dancol.org>
5407 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5408 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5409 accidental message numbering hole. Change other messages to
5412 * w32select.h (HAVE_W32SELECT): Remove.
5414 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5415 w32common.h instead of w32heap.h.
5417 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
5418 (get_allocation_unit, get_processor_type, get_w32_major_version)
5419 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5420 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5421 (OS_NT, os_subtype, cache_system_info): Move declarations to

5425 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5426 (w32_minor_version, w32_build_number, w32_subtype):
5427 Remove duplicate definitions.
5429 * w32fns.c: Include w32common.h; include w32heap.h only in
5432 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5433 Use `report_file_error' instead of `error' in order to better
5434 inform users of what went wrong. Increase NTGUI_UNICODE file
5435 dialog box file name length to 32k, the maximum allowed by the NT
5438 * w32common.h: New file.
5439 (ROUND_UP, ROUND_DOWN, get_page_size)
5440 (get_allocation_unit, get_processor_type, get_w32_major_version)
5441 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5442 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5443 (OS_NT, os_subtype, cache_system_info): Move here.
5445 * unexw32.c, unexcw.c: Include w32common.h.
5447 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5448 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5449 to call syms_of_w32select.
5451 * cygw32.h: Remove obsolete EXFUN declarations.
5453 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

5456 of w32inevt.o from SOME_MACHINE_OBJECTS.
5458 2012-10-08 Daniel Colascione <dancol@dancol.org>
5460 * image.c: Permanent fix for JPEG compilation issue --- limit
5461 jpeglib `boolean' redefinition to Cygwin builds.
5463 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5465 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5467 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5470 2012-10-08 Daniel Colascione <dancol@dancol.org>
5472 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5473 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5474 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5475 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5476 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5477 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5478 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5479 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5480 now a supported configuration.
5482 * Makefile.in: consolidate image variables into LIBIMAGE; add
5483 W32_OBJ and W32_LIBS. Compile new files.
5486 (_DebPrint) declare tracing facility for W32 debugging. We need
5487 to unify tracing later.
5489 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5490 unconditional use of W32 Unicode functions. Cygwin runs only on
5491 100% Unicode operating systems.
5493 * cygw32.c: New file. Define Cygwin-specific facilities.
5494 (Fcygwin_convert_path_to_windows)
5495 (Fcygwin_convert_path_from_windows): New user functions for
5496 accessing Cygwin path-munging routines.
5498 * cygw32.h: New file.
5499 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5500 UTF-16LE strings temporarily inside non-Lisp-visible string
5503 (w32_strerror): Just what it says on the tin.
5505 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5506 also run for Cygwin; both systems have the same problem with using
5507 GUI facilities in a forked child. Also call syms_of_cygw32,
5508 syms_of_w32select in correct places.
5510 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5511 needs fork-then-exec for daemon launching.
5513 * font.h: Include frame.h.
5515 * image.c: Use the image library cache machinery only when we're
5516 compiling for native WINDOWSNT; Cygwin can use shared libraries
5517 like any other Unixlike system.
5519 * keyboard.c: Clarify a comment regarding the input loop.
5521 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5522 functions directly instead of trying to detect at runtime that our
5523 host operating system supports them. We make this change for two
5524 reasons: Cygwin lacks support for the multibyte character
5525 conversion functions used by the legacy menu code, and Cygwin
5526 never needs to rely on non-Unicode APIs.
5528 * unexw32.c (hinst): Declare extern.
5530 * w32.c: Change header order;
5531 (w32_strerror): Move to w32fns.c because we need it for
5532 non-WINDOWSNT builds.
5534 * w32.h: Add #error macro to make sure we don't include w32.h for
5535 Cygwin builds. Remove w32select declarations.
5537 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5538 w32fns.c. w32console.c is WINDOWSNT-only.
5540 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5541 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5543 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5544 (w32_major_version, w32_minor_version, w32_build_number)
5545 (os_subtype, sound_type): Define here
5546 (w32_defined_color): Make color parameter const for consistency
5547 with other _defined_color functions.
5548 (w32_createwindow): Unconditionally call w32_init_class instead of
5549 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5550 through the code is complex and unnecessary because class
5551 registration is practically free.
5552 (w32_name_of_message): New EMACSDEBUG-only function.
5553 (Fset_message_beep): Move here
5554 (Fx_open_connection): Require that the display name for Windows be
5555 "w32" for consistency, emacsclient disambiguation, and maybe, one
5556 day, multi-window-system support.
5557 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5558 Cygwin files for W32 GUI facilities, since these clearly don't
5559 expect Cygwin names.
5560 (_DebPrint): Define.
5561 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5562 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5563 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5564 (w32_last_error): Remove.
5566 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5568 * w32heap.c (syspage_mask): Declare here.
5569 (cache_system_info): Remove.

5572 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5573 (w32_console_toggle_lock_key): Move to w32fns.c.
5575 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5577 * w32proc.c (_DebPrint): Move to w32fns.c.
5578 * w32select.c: Include string.h, stdio.h for Cygwin.
5579 * w32select.h: New File.
5581 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5583 (w32_message_fd): New variable. Under Cygwin, holds the file
5584 descriptor the system used to tell us about pending thread
5587 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5588 that prevented compilation under non-WINDOWSNT systems.
5590 (w32_initialize): Open /dev/windows and assign it to
5591 w32_message_fd. Provide w32 feature.
5593 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5594 (WM_EMACS_INPUT_READY): add.
5595 (prepend_msg, w32_message_fd): Declare globally.
5598 (keyboard_handle): Use only when WINDOWSNT.
5599 (notify_msg_ready): New function. Posts a message to the main
5600 thread's message queue under CYGWIN, which wakes up the main
5601 thread from select(2) by making the /dev/windows file descriptor
5602 ready. Under WINDOWSNT, it sets an event the same way the old
5605 (post, prepend_msg): Actually call notify_msg_ready instead of
5606 setting the input event directly.
5608 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5610 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5611 but it still has blocs in it, don't return it to the system,
5612 instead of aborting. (Bug#12402)
5614 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5616 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).

5647 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5649 Improve sys_siglist detection.
5650 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5651 defined as a macro, as is done in Solaris.
5652 (sys_siglist_entries): New macro.
5653 (save_strsignal): Use it.
5654 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5655 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5657 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5659 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5660 fullscreen/Fullscreen.
5662 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5663 tobar_height is new.
5665 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5666 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5667 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

5676 (canBecomeMainWindow): New function.
5678 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5680 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5682 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5684 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5686 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5687 that time stamps of directories could also be changed.
5688 Don't request the too broad GENERIC_WRITE, only the more restrictive
5689 FILE_WRITE_ATTRIBUTES access rights.
5691 * fileio.c (Fset_file_times): Special-case ignoring errors for
5692 directories only on MSDOS, not on MS-Windows.
5694 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5696 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5698 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5700 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5701 see whether CreateFile failed.
5703 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5705 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5706 to avoid similar races.
5707 * keyboard.c (pending_signals): Now bool, not int.
5709 Port timers to OpenBSD, plus check for timer failures.
5710 OpenBSD problem reported by Han Boetes.
5711 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5713 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5714 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5715 like OpenBSD, which has timer_settime but does not declare it.
5716 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5717 whether to use itimerspec-related primitives. All uses of
5718 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5720 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5722 * profiler.c (handle_profiler_signal): Fix a malloc race
5723 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5725 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5727 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5729 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5731 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5732 consistent with the change in return value of 'safe_strsignal'.
5734 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5736 Prefer plain 'static' to 'static inline' (Bug#12541).
5737 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5738 (bidi_set_sor_type, bidi_push_embedding_level)
5739 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

5744 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5745 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5746 Now 'static', not 'static inline'.
5748 Count overruns when profiling; change units to ns.
5749 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5750 Give extra weight to samples after overruns, to attempt to count
5751 the time more accurately.
5752 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5753 the underlying primitives nominally do ns.
5754 (Fprofiler_cpu_start): Document the change. Mention that
5755 the sampling intervals are only approximate.
5757 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5759 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5761 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5762 case for the special 0 coding-system.
5764 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5765 (Fmake_overlay): Remove redundant tests.
5766 (fix_start_end_in_overlays): Remove redundant recentering.
5768 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5770 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5771 Update dependencies.
5773 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5775 Fix a malloc race condition involving strsignal.
5776 A signal can arrive in the middle of a malloc, and Emacs's signal
5777 handler can invoke strsignal, which can invoke malloc, which is
5778 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5779 Fix it by altering the signal handler so that it does not invoke
5781 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5782 * process.c (status_message): Use const pointer, in case strsignal
5783 is #defined to safe_strsignal.
5784 * sysdep.c (sys_siglist, init_signals): Always define and
5785 initialize a substitute sys_siglist if the system does not define
5786 one, even if HAVE_STRSIGNAL.
5787 (safe_strsignal): Rename from strsignal. Always define,
5788 using sys_siglist. Return a const pointer.
5789 * syssignal.h (safe_strsignal): New decl.
5790 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5792 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5794 * w32proc.c (timer_loop): Fix code that waits for timer
5795 expiration, to avoid high CPU usage.
5797 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5799 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5800 (sweep_weak_table): Remove redundant prototypes.
5802 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5804 * emacs.c: Move the inclusion of TERM_HEADER after including
5805 windows.h on WINDOWSNT. This avoids compilation problems with
5808 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5810 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5811 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5812 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5813 as the previous version used 'void *'.
5815 * ralloc.c (ROUNDUP): Fix last change.
5816 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5819 * w32proc.c <disable_itimers>: New static flag.
5820 (init_timers): Initialize it to zero, after creating the critical
5821 sections used by the timer threads.
5822 (term_timers): Set to 1 before deleting the critical sections.
5823 (getitimer, setitimer): If disable_itimers is non-zero, return an
5824 error indication without doing anything. Reported by Fabrice
5825 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5826 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5828 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5831 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5832 term_ntproc after all the other bookkeeping, to get timers working
5833 as long as possible.
5835 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5837 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5838 Suggested by Juri Linkov in
5839 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5841 Prefer plain 'static' to 'static inline' (Bug#12541).
5842 With static functions, modern compilers inline pretty well by
5843 themselves; advice from programmers often hurts as much as it helps.
5844 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5845 this change shrinks the text size of the Emacs executable by 1.1%
5846 without affecting CPU significantly in my benchmark.
5847 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

5927 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
5929 Revert the FOLLOW-SYMLINKS change for file-attributes.
5930 Doing it right would require several changes to Tramp, and there's
5931 not enough time to get that tested before the freeze today.
5932 * dired.c (directory_files_internal, Ffile_attributes):
5935 * frame.c (x_report_frame_params): Port better to wider ints.
5936 Do not assume that EMACS_UINT is the same width as uprintmax_t,
5937 or that pointers can be printed in 15 decimal digits.
5938 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

6119 Suggested by Eli Zaretskii in
6120 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
6122 2012-09-30 Eli Zaretskii <eliz@gnu.org>
6124 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
6125 HAVE_TIMER_SETTIME is defined.
6127 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
6129 Profiler improvements: more-accurate timers, overflow checks.
6130 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
6131 signal.h, setjmp.h. Include systime.h instead.
6132 (saturated_add): New function.

6139 All uses changed to store the new value.
6140 (handle_profiler_signal): Rename from sigprof_handler_1,
6141 for consistency with other handlers. Do not check whether
6142 cpu_log is a hash-table if garbage collecting, since it
6143 doesn't matter in that case.
6144 (deliver_profiler_signal): Rename from sigprof_handler,
6145 for consistency with other handlers.
6146 (setup_cpu_timer): New function, with much of what used to be in
6147 Fprofiler_cpu_start. Check for out-of-range argument.
6148 Prefer timer_settime if available, and prefer
6149 thread cputime clocks, then process cputime clocks, then
6150 monotonic clocks, to the old realtime clock. Use make_timeval
6151 to round more-correctly when falling back to setitimer.
6152 (Fprofiler_cpu_start): Use it.
6153 (Fprofiler_cpu_stop): Prefer timer_settime if available.
6154 Don't assume that passing NULL as the 2nd argument of setitimer
6155 is the same as passing a pointer to all-zero storage.

6157 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
6158 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
6159 non-fatal signal handlers. Ignore SIGPROF on startup.
6160 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
6161 in profiler.c, since sysdep.c now uses it.
6163 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

6218 * charset.c, charset.h (maybe_unify_char): Now static.
6219 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
6220 Since this stuff is now private to charset.c, there's no need for
6221 a public macro and no need to inline by hand.

6254 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>

6293 (sigaction): Rewrite to call sys_signal instead of duplicating its
6295 (sys_kill): Improve commentary.
6297 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6298 consistency with a signature of a signal handler. All callers
6300 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6301 install term_ntproc as a signal handler for SIGABRT, as that
6302 should be done by the dumped Emacs.
6304 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6306 * w32select.c (term_w32select): Protect against repeated
6307 invocation by setting clipboard_owner to NULL after calling
6310 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc

6425 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6426 fatal_error_backtrace.
6428 * w32proc.c (sys_kill): Undo last change: don't do anything when

6430 handled by emacs_raise.
6432 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6434 * w32term.c (w32_read_socket): Remove leftover reference to

6437 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6439 Do not use SA_NODEFER.
6440 Problem reported by Dani Moncayo in
6441 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6443 * sysdep.c (emacs_abort): Do not reset signal handler.
6444 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6445 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6446 wanted even on POSIXish hosts, and it doesn't work on Windows.
6448 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6450 * xterm.c (x_term_init): Call fixup_locale before and after calling
6451 gtk_init (Bug#12392).
6453 2012-09-23 Chong Yidong <cyd@gnu.org>
6455 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6456 Vdynamic_library_alist.
6458 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6459 (Fgnutls_available_p): Caller changed.
6461 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6462 (Flibxml_parse_xml_region): Likewise.
6464 * dispextern.h (struct image_type): Remove arg from init function.
6466 * image.c (Finit_image_library, lookup_image_type)
6467 (define_image_type): Remove now-unneeded second arg.
6468 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6469 (init_tiff_functions, init_gif_functions, init_svg_functions):
6470 Arglist and w32_delayed_load calling convention changed.
6471 (gs_type): Remove init_gs_functions; there is no such function.
6472 (valid_image_p, make_image): Fix caller to lookup_image_type.
6474 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6476 Simplify and avoid signal-handling races (Bug#12471).
6478 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6479 Avoid recursive loop if there's a fatal error in the function itself.
6480 * atimer.c (pending_atimers):
6481 * blockinput.h: Don't include "atimer.h"; no longer needed.
6482 (interrupt_input_pending): Remove. All uses removed.
6483 pending_signals now counts both atimers and ordinary interrupts.
6484 This is less racy than having three separate pending-signal flags.
6485 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6487 Rename from their upper-case counterparts BLOCK_INPUT,
6488 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6489 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6490 This makes it easier to access volatile variables more accurately.
6491 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6492 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6493 that's more reliable if the code is buggy and sets
6494 interrupt_input_blocked to a negative value. All uses changed.
6495 * atimer.c (deliver_alarm_signal):
6496 Remove. No need to deliver this to the parent; any thread can
6497 handle this signal now. All uses replaced by underlying handler.
6498 * atimer.c (turn_on_atimers):
6499 * dispnew.c (handle_window_change_signal):
6500 * emacs.c (handle_danger_signal):
6501 * keyboard.c (kbd_buffer_get_event):
6502 Don't reestablish signal handler; not needed with sigaction.
6503 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6505 Rework to avoid unnecessary accesses to volatile variables.
6506 (UNBLOCK_INPUT_TO): Now a function.
6507 (totally_unblock_input, unblock_input): New decls.
6508 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6509 (init_data): Remove. Necessary stuff now done in init_signal.
6510 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6511 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6512 (fatal_error_code): Remove; no longer needed.
6513 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6514 it doesn't always backtrace. All uses changed. No need to reset
6515 signal to default, since sigaction and/or die does that for us now.
6516 Use emacs_raise (FOO), not kill (getpid (), FOO).
6517 (main): Check more-accurately whether we're dumping.
6518 Move fatal-error setup to sysdep.c
6519 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6520 * gtkutil.c (xg_get_file_name, xg_get_font):
6521 Remove no-longer-needed signal-mask manipulation.
6522 * keyboard.c, process.c (POLL_FOR_INPUT):
6523 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6524 * keyboard.c (read_avail_input): Remove.
6525 All uses replaced by gobble_input.
6526 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6527 (kbd_buffer_store_event_hold, gobble_input):
6528 (record_asynch_buffer_change) [USABLE_SIGIO]:
6529 (store_user_signal_events):
6530 No need to mess with signal mask.
6531 (gobble_input): If blocking input and there are terminals, simply
6532 set pending_signals to 1 and return. All hooks changed to not
6533 worry about whether input is blocked.
6534 (process_pending_signals): Clear pending_signals before processing
6535 them, in case a signal comes in while we're processing.
6536 By convention callers now test pending_signals before calling us.
6537 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6538 New functions, to support changes to blockinput.h.
6539 (handle_input_available_signal): Now extern.
6540 (reinvoke_input_signal): Remove. All uses replaced by
6542 (quit_count): Now volatile, since a signal handler uses it.
6543 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6544 All callers changed. Block SIGINT only if not already blocked.
6545 Clear sigmask reliably, even if Fsignal returns, which it can.
6546 Omit unnecessary accesses to volatile var.
6547 (quit_throw_to_read_char): No need to restore sigmask.
6548 * keyboard.c (gobble_input, handle_user_signal):
6549 * process.c (wait_reading_process_output):
6550 Call signal-handling code rather than killing ourselves.
6551 * lisp.h: Include <float.h>, for...
6552 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6553 (pending_signals): Now volatile.
6554 (syms_of_data): Now const if IEEE floating point.
6555 (handle_input_available_signal) [USABLE_SIGIO]:
6556 (terminate_due_to_signal, record_child_status_change): New decls.
6557 * process.c (create_process): Avoid disaster if memory is exhausted
6558 while we're processing a vfork, by tightening the critical section
6560 (send_process_frame, process_sent_to, handle_pipe_signal)
6561 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6563 (send_process): No need for setjmp/longjmp any more, since the
6564 SIGPIPE stuff is now gone. Instead, report an error if errno
6566 (record_child_status_change): Now extern. PID and W are now args.
6567 Return void, not bool. All callers changed.
6568 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6569 Remove. All uses removed. This bug should be fixed now in a
6571 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6572 and record the child status change directly. This avoids the
6573 need to futz with the signal mask.
6574 (process_fatal_action): Move here from emacs.c.
6575 (emacs_sigaction_flags): New function, containing
6576 much of what used to be in emacs_sigaction_init.
6577 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6578 caught by emacs, to make races less likely.
6579 (deliver_process_signal): Rename from handle_on_main_thread.
6581 (BACKTRACE_LIMIT_MAX): Now at top level.
6582 (thread_backtrace_buffer, threadback_backtrace_pointers):
6584 (deliver_thread_signal, deliver_fatal_thread_signal):
6585 New functions, for more-accurate delivery of thread-specific signals.
6586 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6587 (deliver_arith_signal): Handle in this thread, not
6588 in the main thread, since it's triggered by this thread.
6589 (maybe_fatal_sig): New function.
6590 (init_signals): New arg DUMPING so that we can be more accurate
6591 about whether we're dumping. Caller changed.
6592 Treat thread-specific signals differently from process-general signals.
6593 Block all signals while handling fatal error; that's safer.
6594 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6596 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6597 Ignore SIGPIPE unless batch.
6598 (emacs_backtrace): Output backtrace for the appropriate thread,
6599 which is not necessarily the main thread.
6600 * syssignal.h: Include <stdbool.h>.
6601 (emacs_raise): New macro.
6602 * xterm.c (x_connection_signal): Remove; no longer needed
6603 now that we use sigaction.
6604 (x_connection_closed): No need to mess with sigmask now.
6605 (x_initialize): No need to reset SIGPIPE handler here, since
6606 init_signals does this for us now.
6608 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6610 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6611 background rect may be larger (Bug#12245).
6613 2012-09-23 Chong Yidong <cyd@gnu.org>
6615 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6617 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6619 * .gdbinit: Just stop at fatal_error_backtrace.
6620 See Stefan Monnier's request in
6621 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6622 Remove no-longer-used query of system type.
6624 2012-09-22 Chong Yidong <cyd@gnu.org>
6626 * search.c (Freplace_match): Doc fix (Bug#12325).
6628 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6630 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6631 (Fline_end_position): Doc fix.
6633 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6635 2012-09-22 Chong Yidong <cyd@gnu.org>
6637 * dispextern.h (struct image_type): Add new slot, storing a type
6638 initialization function.
6640 * image.c (define_image_type): Call the image initializer function
6641 if it is defined. Arguments and return value changed.
6642 (valid_image_p, make_image): Callers changed.
6643 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6644 (gif_type, imagemagick_type, svg_type, gs_type):
6645 Add initialization functions.
6646 (Finit_image_library): Call lookup_image_type.
6647 (CHECK_LIB_AVAILABLE): Macro deleted.
6648 (lookup_image_type): Call define_image_type here, rather than via
6649 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6650 (syms_of_image): Move define_image_type calls for xbm_type and
6651 pbm_type to lookup_image_type.
6653 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6655 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6656 'idle_timers' from here ...
6657 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6658 lists, to avoid infloops when the timer does something stupid,
6659 like reinvoke itself with the same or smaller time-out.
6662 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6664 * window.c (Fsplit_window_internal): Handle only Qt value of
6665 Vwindow_combination_limit separately.
6666 (Qtemp_buffer_resize): New symbol.
6667 (Vwindow_combination_limit): New default value.
6670 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6672 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6673 the new overlay string. (Bug#10159)
6675 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6677 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6678 or that fprintf is async-signal-safe. POSIX doesn't require
6681 2012-09-22 Chong Yidong <cyd@gnu.org>
6683 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6686 2012-09-22 Kenichi Handa <handa@gnu.org>
6688 * composite.c (composition_reseat_it): Handle the case that a
6689 grapheme cluster is not covered by a single font (Bug#12352).
6691 2012-09-21 Chong Yidong <cyd@gnu.org>
6693 * image.c (define_image_type): Avoid adding duplicate types to
6694 image_types (Bug#12463). Suggested by Jörg Walter.
6696 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6698 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6699 (print_load_command_name): Add case LC_DATA_IN_CODE.
6700 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6702 2012-09-21 Glenn Morris <rgm@gnu.org>
6704 * eval.c (Frun_hook_with_args_until_success)
6705 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6707 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6709 * fileio.c (Ffile_selinux_context): Only call freecon when
6710 lgetfilecon succeeded.
6711 (Fset_file_selinux_context): Likewise. (Bug#12444)
6713 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6715 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6716 reordering, locate the cursor by calling set_cursor_from_row; if
6717 that fails, clear the desired glyph matrix before returning a
6718 failure indication to the caller. Fixes leaving garbled display
6719 when fast scrolling with a down-key. (Bug#12403)
6720 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6721 scrolling through multibyte text.
6723 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6725 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6726 calling mark_vectorlike since that's the one that marks the window.
6727 (mark_discard_killed_buffers): Mark the final cdr.
6728 * window.h (struct window): Move prev/next_buffers to the
6729 non-standard fields.
6730 * window.c (make_window): Initialize prev/next_buffers manually.
6732 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6734 Omit unused arg EXPECTED from socket hooks.
6735 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6736 * nsterm.m (ns_term_init):
6737 * termhooks.h (struct terminal.read_socket_hook):
6738 * w32inevt.c (w32_console_read_socket):
6739 * w32term.c (w32_read_socket):
6740 * xterm.c (XTread_socket):
6741 Omit unused arg EXPECTED. All callers changed.
6742 (store_user_signal_events): Return void, not int, since callers no
6743 longer care about the return value. All uses changed.
6745 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6747 * w32gui.h (XParseGeometry): Do not declare.
6749 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6751 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6752 Ignore 'expected'. See Eli Zaretskii in
6753 <http://bugs.gnu.org/12471#8> (last line).
6755 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6756 (XParseGeometry): Now static. Substitute extremal values for
6757 values that are out of range.
6759 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6761 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6763 * nsfns.m (XParseGeometry): Remove.
6764 (Fx_create_frame): Call x_set_offset to correctly interpret
6765 top_pos in geometry.
6767 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6768 (Fx_parse_geometry): If there is a space in string, call
6769 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6771 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6773 * search.c (scan_buffer): Use character positions in calls to
6774 region_cache_forward and region_cache_backward, not byte
6775 positions. (Bug#12196)
6777 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6778 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6780 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6781 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6782 emacs_blocked_malloc, now deleted.
6784 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6786 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6787 The workaround was for improving performance on Solaris 2.4, but
6788 is getting in the way now. Emacs will still work if someone is
6789 still running Solaris 2.4 in a museum somewhere; Sun dropped
6790 support for Solaris 2.4 in 2003.
6791 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6792 * process.c (create_process) [HAVE_WORKING_VFORK]:
6793 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6794 since Emacs no longer uses vfork on that platform.
6796 2012-09-17 Glenn Morris <rgm@gnu.org>
6798 * emacs.c: Use COPYRIGHT.
6800 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6802 Remove configure's --without-sync-input option (Bug#12450).
6803 When auditing signal-handling in preparation for cleaning it up,
6804 I found that SYNC_INPUT has race conditions and would be a real
6805 pain to fix. Since it's an undocumented and deprecated
6806 configure-time option, now seems like a good time to remove it.
6807 Also see <http://bugs.gnu.org/11080#16>.
6808 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6809 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6810 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6811 (malloc_hysteresis):
6812 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6813 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6814 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6815 (dont_register_blocks, bytes_used_when_reconsidered)
6816 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6817 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6818 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6819 Remove. All uses removed.
6820 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6821 implementation, one that depends on whether the new macro
6822 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6824 * atimer.c (run_timers, handle_alarm_signal):
6825 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6826 (handle_async_input, process_pending_signals)
6827 (handle_input_available_signal, init_keyboard):
6828 * nsterm.m (ns_read_socket):
6829 * process.c (wait_reading_process_output):
6830 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6831 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6833 * xterm.c (XTread_socket):
6835 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6836 * eval.c (handling_signal): Remove. All uses removed.
6837 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6838 All uses replaced with the SYNC_INPUT version.
6839 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6841 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6844 * font.c (Ffont_shape_gstring): Remove unused local.
6846 2012-09-16 Glenn Morris <rgm@gnu.org>
6848 * Makefile.in (clean): No longer run nextstep's clean.
6850 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6852 (ns-app): Move here from ns.mk, and simplify.
6853 (clean): Simplify nextstep entry.
6854 * ns.mk: Remove file.
6856 2012-09-17 Kenichi Handa <handa@gnu.org>
6858 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6859 not covert the last few charactes.
6861 2012-09-16 Kenichi Handa <handa@gnu.org>
6863 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6864 here, but just check the validity of glyphs in the glyph-string.
6866 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6868 * window.c (Fwindow_parameter, Fset_window_parameter):
6869 Accept any window as argument (Bug#12452).
6871 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6873 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6874 to ns_term_init to avoid memory leak.
6876 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6877 explicit retain/release.
6878 (ns_term_init): Only allow one display. Initialize outerpool and
6881 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6883 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6884 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6885 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6886 the Microsoft problem in a different way, by altering ../nt/config.nt.
6888 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6903 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6904 by lisp.h. This completes removal of setjmp.h inclusion
6905 erroneously announced in the previous commit. (Bug#12446)
6907 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6910 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6911 not defined as a macro. The latter happens on MS-Windows.
6914 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6916 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6917 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6918 Some instances of '#include <setjmp.h>' removed, if the
6919 only reason for the instance was because "lisp.h" was included.
6920 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6921 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6922 and _longjmp with the new symbols. Emacs already uses _setjmp if
6923 available, so this change affects only POSIXish hosts that have
6924 sigsetjmp but not _setjmp, such as some versions of Solaris and
6925 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6926 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6927 (png_load_body) [HAVE_PNG]:
6928 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6929 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6930 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6931 since PNG requires jmp_buf. This is the only exception to the
6932 general rule that we now use sys_setjmp and sys_longjmp.
6933 This exception is OK since this code does not change the signal
6934 mask or longjmp out of a signal handler.
6936 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6938 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6939 Include "syssignal.h", for 'main_thread'.
6941 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6943 Avoid out-of-range marker position (Bug#12426).
6944 * insdel.c (replace_range, replace_range_2):
6945 Adjust markers before overlays, as suggested by comments.
6946 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6947 Remove redundant check before calling offset_intervals.
6949 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6951 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6952 current buffer (Bug#12387).
6954 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6956 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6958 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6960 Use a more backwards-compatible timer format (Bug#12430).
6961 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6962 vector element, not from the 4th, since PSECS is now at the end.
6963 (Fcurrent_idle_time): Doc fix.
6965 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6967 Function to mark objects and remove killed buffers at once.
6968 * alloc.c (discard_killed_buffers): Rename to ...
6969 (mark_discard_killed buffers) ... new name. Add marking
6970 of remaining objects. Fix comment. Adjust users.
6971 (mark_object): Do not touch frame buffer lists here.
6972 * frame.c (delete_frame): Reset frame buffer lists here.
6974 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6976 Better workaround for GNOME bug when --enable-gcc-warnings.
6977 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6978 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6979 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6981 Simplify SIGIO usage (Bug#12408).
6982 The code that dealt with SIGIO was crufty and confusing, e.g., it
6983 played tricks like "#undef SIGIO" but these tricks were not used
6984 consistently. Simplify mostly by not #undeffing standard symbols,
6985 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6986 or not as we please) rather than "defined SIGIO" (standard symbol
6987 that we probably shouldn't #undef).
6988 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6989 Modules that need it can include it.
6990 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6991 * dispextern.h (ignore_sigio): New decl.
6992 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6993 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6994 * emacs.c (shut_down_emacs):
6995 * keyboard.c (kbd_buffer_store_event_hold):
6996 Use ignore_sigio rather than invoking 'signal' directly.
6997 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6999 (FIONREAD, SIGIO): Do not #undef.
7000 (tty_read_avail_input): Use #error rather than a syntax error.
7001 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
7002 for I_PIPE, used by SETUP_SLAVE_PTY.
7003 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
7004 * sysdep.c (croak): Remove; no longer needed. This bit of
7005 temporary code, with Fred N. Fish's comment that it's temporary,
7006 has been in Emacs since at least 1992!
7007 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
7008 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
7009 * syssignal.h (croak): Remove decl.
7010 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
7011 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
7012 now that we're termios-only.
7013 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
7014 * term.c (dissociate_if_controlling_tty): Use #error rather than
7017 Work around GCC and GNOME bugs when --enable-gcc-warnings.
7018 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
7019 to work around GNOME bug 683906.
7020 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
7021 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
7022 This works around GCC bug 54561.
7024 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7026 More fixes for 'volatile' and setjmp/longjmp.
7027 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
7028 * image.c (struct png_load_context) [HAVE_PNG]: New type.
7029 (png_load_body) [HAVE_PNG]:
7030 (jpeg_load_body) [HAVE_JPEG]:
7031 New function, with most of the old parent function's body.
7032 (png_load) [HAVE_PNG]:
7033 (jpeg_load) [HAVE_JPEG]:
7034 Invoke the new function, to avoid longjmp munging our locals.
7035 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
7036 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
7037 longjmp is passed 2, as the C standard doesn't guarantee this.
7038 Instead, store the failure code into mgr->failure_code.
7040 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7042 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
7043 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
7044 (syms_of_keyboard): Remove support for unread-command-char.
7046 2012-09-12 Eli Zaretskii <eliz@gnu.org>
7048 * w32proc.c (sys_kill): If PID is our process ID and the signal is
7049 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
7050 violation. (Bug#12426)
7052 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7054 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
7056 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7058 * eval.c: Add `inhibit-debugger'.
7059 (Qinhibit_debugger): New symbol.
7060 (call_debugger): Bind it instead of Qdebug_on_error.
7061 (maybe_call_debugger): Test Vinhibit_debugger.
7062 (syms_of_eval): Define inhibit-debugger.
7063 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
7064 (syms_of_xdisp): Remove inhibit-debug-on-message.
7066 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7068 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
7069 If a nonvolatile local variable is written before a _longjmp to
7070 the frame containing the variable, and is read after the _longjmp,
7071 the value read is indeterminate. Some local variables of type
7072 'struct handler' and 'struct catchtag' are used in this way, so
7073 mark each of their slots as volatile if the slot can be set before
7074 _longjmp and read afterwards.
7075 * lisp.h (struct handler): var and chosen_clause are now volatile.
7076 (struct catchtag): val, next, and pdlcount are now volatile.
7078 * bidi.c (bidi_push_it, bidi_pop_it):
7079 * fns.c (copy_hash_table):
7080 * image.c (define_image_type):
7081 * keyboard.c (kbd_buffer_store_event_hold):
7082 * process.c (Fprocess_send_eof):
7083 * xfaces.c (x_create_gc) [HAVE_NS]:
7084 * xgselect.c (xg_select):
7085 Prefer assignment to memcpy when either will do.
7087 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
7088 Use pointer-to-a-pointer to simplify and avoid a NILP check each
7089 time an item is removed. No need to mark this function 'inline';
7090 the compiler knows better than we do.
7092 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
7094 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
7095 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
7096 to change_frame_size (Bug#12388).
7097 (windowDidResize:): Pass YES to updateFrameSize.
7099 * nsterm.h: Add delay parameter to updateFrameSize.
7101 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7103 Discard killed buffers from deleted window and frame objects.
7104 This reduces an amount of references to killed buffers and
7105 helps GC to reclaim them faster.
7106 * alloc.c (discard_killed_buffers): New function.
7107 (mark_object): Use it for deleted windows and frames.
7108 (mark_object): If symbol's value is set up for a killed buffer
7109 or deleted frame, restore its global binding.
7110 * data.c (swap_in_global_binding): Add GC notice.
7111 (swap_in_symval_forwarding): Use convenient set_blv_where.
7112 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
7113 * window.h: ... to here.
7115 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7117 Convenient macro to check whether the buffer is live.
7118 * buffer.h (BUFFER_LIVE_P): New macro.
7119 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
7120 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
7122 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7124 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
7125 composition cases (Bug#12364).
7127 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
7128 overhang of succeeding glyphs overlapping box cursor.
7130 * w32term.c (x_draw_glyph_string): Likewise.
7132 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7134 Simplify, document, and port floating-point (Bug#12381).
7135 The porting part of this patch fixes bugs on non-IEEE platforms
7136 with frexp, ldexp, logb.
7137 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
7139 * floatfns.c: Simplify discussion of functions that Emacs doesn't
7140 support, by removing commented-out code and briefly listing the
7141 C89 functions excluded. The commented-out stuff was confusing
7142 maintenance, e.g., we thought we needed cbrt but it was commented out.
7143 (logb): Remove decl; no longer needed.
7144 (isfinite): New macro, if not already supplied.
7145 (isnan): Don't replace any existing macro.
7146 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
7147 are present on all C89 platforms.
7148 (Ffrexp): Do not special-case zero, as frexp does the right thing
7150 (Flogb): Do not use logb, as it doesn't have the desired meaning
7151 on hosts that use non-base-2 floating point. Instead, stick with
7152 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
7153 frexp, to avoid getting an unspecified result.
7155 * xdisp.c (Qinhibit_debug_on_message): Now static.
7157 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
7159 * nsterm.m (ns_update_begin): Set clip path to whole view by using
7160 NSBezierPath (Bug#12131).
7162 2012-09-10 Chong Yidong <cyd@gnu.org>
7164 * fns.c (Fdelq, Fdelete): Doc fix.
7166 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
7168 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
7169 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
7171 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
7173 * lisp.h (make_lisp_ptr): New macro to replace XSET.
7174 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
7177 2012-09-09 Eli Zaretskii <eliz@gnu.org>
7179 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
7180 left fringe if the window has a left margin. This avoids leaving
7181 traces of the cursor because its leftmost pixel is not drawn over.
7183 * dispnew.c (update_window_line): When the left margin area of a
7184 screen line is updated, set the redraw_fringe_bitmaps_p flag of
7185 that screen line. (Bug#12277)
7187 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
7189 Assume C89 or later for math functions (Bug#12381).
7190 This simplifies the code, and makes it a bit smaller and faster,
7191 and (most important) makes it easier to clean up signal handling
7192 since we can stop worring about floating-point exceptions in
7193 library code. That was a problem before C89, but the problem
7194 went away many years ago on all practical Emacs targets.
7195 * data.c, image.c, lread.c, print.c:
7196 Don't include <math.h>; no longer needed.
7197 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
7198 might be autoconfigured, as that never happens.
7200 * doprnt.c (DBL_MAX_10_EXP):
7201 * print.c (DBL_DIG):
7202 Remove. C89 or later always defines these.
7203 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
7204 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
7205 (arith_error, domain_error, domain_error2):
7206 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
7207 no longer needed -- we simply return what C returns. All uses removed.
7208 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
7210 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
7211 Remove. All uses expanded, as these macros are no longer used
7212 more than once and are now more trouble than they're worth.
7213 (Ftan): Use tan, not sin / cos.
7214 (Flogb): Assume C89 frexp.
7215 (fmod_float): Assume C89 fmod.
7216 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
7217 (init_floatfns): Remove. All uses removed.
7219 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7221 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
7222 compositeToPoint for OSX < 10.6 (Bug#12390).
7224 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
7226 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
7227 This produces more-accurate results.
7229 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7231 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
7232 changes (Bug#12088).
7234 2012-09-08 Chong Yidong <cyd@gnu.org>
7236 * syntax.c (Fstring_to_syntax): Doc fix.
7238 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7240 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
7241 in the internal border.
7242 (x_set_window_size): Remove static variables and their usage.
7243 (ns_redraw_scroll_bars): Fix NSTRACE arg.
7244 (ns_after_update_window_line, ns_draw_fringe_bitmap):
7245 Remove fringe/internal border adjustment (Bug#11052).
7246 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
7247 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
7248 (ns_fix_rect_ibw): Remove.
7249 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
7250 (ns_dumpglyphs_box_or_relief): Ditto.
7251 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
7253 (ns_dumpglyphs_image): Ditto.
7254 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
7256 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
7257 their usage. Add fringe_extended_p and its use as in other terms.
7258 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
7259 scroll bar was removed.
7260 (updateFrameSize): New function.
7261 (windowDidResize): Move code to updateFrameSize and call it.
7263 * nsterm.h (EmacsView): Add updateFrameSize.
7265 2012-09-07 Chong Yidong <cyd@gnu.org>
7267 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
7269 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
7271 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7273 More signal-handler cleanup (Bug#12327).
7274 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
7275 Problem introduced when merging patches. Noted by Eli Zaretskii in
7276 <http://bugs.gnu.org/12327#67>.
7277 * floatfns.c: Comment fix.
7278 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
7279 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
7280 and anyway the declaration is harmless even if SIGDANGER is not defined.
7281 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
7282 defined BROKEN_FIONREAD). systty.h formerly did this, but other
7283 source files not surprisingly expected syssignal.h to define, or
7284 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7285 Include <sys/ioctl.h>, for FIONREAD.
7286 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7287 This eliminates a problem whereby other files mysteriously had
7288 to include "syssignal.h" before including "systty.h" if they
7289 wanted to use "#ifdef SIGIO".
7291 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7293 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7295 * w32.c (sigemptyset): Empty the set.
7296 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7298 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7300 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7302 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7303 (mark_object): Likewise for frame objects.
7305 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7307 * syssignal.h (handle_on_main_thread): Always declare,
7308 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7309 This ports to platforms without HAVE_PTHREAD.
7311 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7313 Signal-handler cleanup (Bug#12327).
7314 Emacs's signal handlers were written in the old 4.2BSD style with
7315 sigblock and sigmask and so forth, and this led to some
7316 inefficiencies and confusion. Rewrite these to use
7317 pthread_sigmask etc. without copying signal sets around. Also,
7318 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7319 'signal', and instead use functions that do not attempt to take
7320 over the system name space. This patch causes Emacs's text
7321 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7322 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7323 Do not include <signal.h> or "syssignal.h", as these
7324 modules do not use signals.
7325 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7326 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7327 Do not include <signal.h>, as "syssignal.h" does that for us now.
7328 * atimer.c (sigmask_atimers): New function.
7329 (block_atimers, unblock_atimers): New functions,
7330 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7332 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7333 no longer needed here.
7334 * emacs.c (main): Inspect existing signal handler with sigaction,
7335 so that there's no need to block and unblock SIGHUP.
7336 * sysdep.c (struct save_signal): New member 'action', replacing
7337 old member 'handler'.
7338 (save_signal_handlers, restore_signal_handlers):
7339 Use sigaction instead of 'signal' to save and restore.
7340 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7341 New function. All users of 'signal' modified to use set_sighandler
7342 if they're writeonly, and to use sys_signal if they're read+write.
7343 (emacs_sigaction_init, forwarded_signal): New functions.
7344 (sys_signal): Remove. All uses replaced by calls to sigaction
7345 and emacs_sigaction_init, or by direct calls to 'signal'.
7346 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7347 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7348 all uses replaced by pthread_sigmask etc. calls.
7349 * syssignal.h: Include <signal.h>.
7350 (emacs_sigaction_init, forwarded_signal): New decls.
7351 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7352 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7353 (sigmask, sys_sigmask): Remove; no longer needed.
7354 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7355 (sigblock, sigunblock, sigfree):
7356 (sigsetmask) [!defined sigsetmask]:
7357 Remove. All uses replaced by pthread_sigmask.
7358 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7359 no longer need to be replaced, and its typical old uses
7360 are now done via emacs_sigaction_init and sigaction.
7361 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7362 (sys_sigdel): Remove; unused.
7363 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7365 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7367 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7368 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7370 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7372 Explicitly mark buffer_defaults and buffer_local_symbols.
7373 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7374 mark_local_symbols here.
7375 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7376 since special buffers aren't marked here any more.
7377 (allocate_buffer): Chain new buffer with all_buffers here...
7378 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7380 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7381 (syms_of_buffer): Remove staticpro of the above.
7382 (init_buffer_once): Set names for buffer_defaults and
7383 buffer_local_symbols.
7385 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7387 Use bool for booleans in font-related modules.
7388 * font.c (font_intern_prop, font_style_to_value)
7389 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7390 (generate_otf_features, font_check_otf_features, font_check_otf)
7391 (font_match_p, font_list_entities, font_at):
7392 * fontset.c (fontset_id_valid_p, reorder_font_vector
7393 (fontset_find_font, Fset_fontset_font)
7394 (face_suitable_for_char_p) [0]:
7395 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7396 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7397 (m17n_flt_initialized, ftfont_shape_by_flt):
7398 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7399 * nsfont.m (nsfont_draw):
7400 * w32font.c (w32font_draw):
7401 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7402 Use bool for booleans.
7403 * font.h: Adjust to above API changes.
7404 (struct font, struct font_driver, struct font_driver_list):
7405 Use bool for booleans.
7406 (struct font): Remove useless member encoding_type.
7408 * fontset.c, xftfont.c: Omit unnecessary static decls.
7410 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7412 * alloc.c (mark_object): Revert window marking code
7413 since it's unsafe for the Fset_window_configuration.
7415 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7417 Fix race conditions with signal handlers and errno (Bug#12327).
7418 Be more systematic about preserving errno whenever a signal
7419 handler returns, even if it's not in the main thread. Do this by
7420 renaming signal handlers to distinguish between signal delivery
7421 and signal handling. All uses changed.
7422 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7423 * data.c (deliver_arith_signal): Rename from arith_error.
7424 * dispnew.c (deliver_window_change_signal): Rename from
7425 window_change_signal.
7426 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7427 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7428 * keyboard.c (deliver_input_available_signal): Rename from
7429 input_available_signal.
7430 (deliver_user_signal): Rename from handle_user_signal.
7431 (deliver_interrupt_signal): Rename from interrupt_signal.
7432 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7433 (deliver_child_signal): Rename from sigchld_handler.
7434 * atimer.c (handle_alarm_signal):
7435 * data.c (handle_arith_signal):
7436 * dispnew.c (handle_window_change_signal):
7437 * emacs.c (handle_fatal_signal, handle_danger_signal):
7438 * keyboard.c (handle_input_available_signal):
7439 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7440 * process.c (handle_pipe_signal, handle_child_signal):
7441 New functions, with the actual signal-handling code taken from the
7442 original respective signal handlers, sans the sporadic attempts to
7443 preserve errno, since that's now done by handle_on_main_thread.
7444 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7445 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7446 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7448 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7449 Move initialization of main_thread to sysdep.c's init_signals.
7450 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7451 our usage, and simplifies the mainline code.
7452 (record_child_status_change): New static function, as a helper
7453 for handle_child_signal, and with most of the old child handler's
7455 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7456 (handle_child_signal): Use the above.
7457 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7458 Moved here from emacs.c.
7459 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7460 code moved here from emacs.c's main function.
7461 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7462 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7463 This lets callers save and restore errno properly.
7465 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7467 Remove redundant or unused things here and there.
7468 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7469 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7470 * editfns.c (Fcompare_buffer_substrings): Likewise.
7471 * frame.h (struct terminal, struct font_driver_list):
7472 Remove redundant declarations.
7473 * window.h (Qleft, Qright): Likewise.
7475 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7477 Do not mark objects from deleted buffers, windows and frames.
7478 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7479 (mark_object): Likewise for windows and frames.
7481 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7483 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7484 buffer_defaults and buffer_local_symbols as valid objects.
7485 Return special value to denote them.
7487 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7489 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7490 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7491 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7492 (file_name_absolute_p, Fsubstitute_in_file_name):
7493 (check_executable, check_writable, Ffile_accessible_directory_p)
7494 (Fset_file_selinux_context, Fdefault_file_modes)
7495 (Finsert_file_contents, choose_write_coding_system)
7496 (Fwrite_region, build_annotations, a_write, e_write)
7498 * filelock.c (boot_time_initialized, get_boot_time)
7499 (get_boot_time_1, lock_file_1, within_one_second):
7500 * floatfns.c (in_float):
7501 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7502 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7503 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7504 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7505 * window.c (compare_window_configurations):
7506 Use bool for booleans.
7507 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7508 (Fdefault_file_modes): Now mode_t, not int, for modes.
7509 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7510 (internal_delete_file): Now returns void, not a (boolean) int,
7511 since nobody was looking at the return value.
7512 * lisp.h, window.h: Adjust to above API changes.
7514 * xdisp.c (set_message): Simplify and reindent last change.
7516 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7518 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7520 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7522 * eval.c (call_debugger): Make the function non-static so that we
7523 can call it from set_message.
7525 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7526 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7528 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7530 Give more-useful info on a fatal error (Bug#12328).
7531 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7532 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7533 of doing the work ourselves.
7534 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7535 do most of the work.
7536 (fatal_error_backtrace): New function, taken from the guts
7537 of the old fatal_error_signal, but with a new option to output
7539 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7540 info about the signal than just its number.
7541 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7542 * sysdep.c: Include <execinfo.h>
7543 (emacs_backtrace): New function, taken partly from the previous
7544 code of the 'die' function.
7545 (emacs_abort): Call fatal_error_backtrace rather than abort.
7547 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7549 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7550 eager (load-time) macro-expansion.
7551 * lisp.mk (lisp): Add macroexp.
7553 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7555 Simplify redefinition of 'abort' (Bug#12316).
7556 Do not try to redefine the 'abort' function. Instead, redo
7557 the code so that it calls 'emacs_abort' rather than 'abort'.
7558 This removes the need for the NO_ABORT configure-time macro
7559 and makes it easier to change the abort code to do a backtrace.
7560 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7561 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7562 Remove; sysdep.c's emacs_abort now takes its place.
7563 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7564 'abort' changed to use 'emacs_abort'.
7565 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7566 (abort) [!defined abort]: Rename to ...
7567 (emacs_abort): ... new name.
7568 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7569 the place of the old 'abort' in emacs.c.
7570 * w32.c, w32fns.c (abort): Do not #undef.
7571 * w32.c (emacs_abort): Rename from w32_abort.
7573 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7575 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7576 offsets[j].dv, since the y axis of the screen coordinates points
7577 down, while the y axis of the font definition coordinates points
7578 up. This fixes display of Arabic diacritics such as KASRA and
7579 KASRATAN. (Bug#11860)
7581 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7583 Be more systematic about _setjmp vs setjmp.
7584 * alloc.c (test_setjmp, mark_stack):
7585 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7586 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7587 (png_load, my_error_exit, jpeg_load):
7588 * process.c (send_process_trap, send_process):
7589 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7590 The underscored versions are up to 30x faster on some hosts.
7591 Formerly, the code used setjmp+longjmp sometimes and
7592 _setjmp+_longjmp at other times, with no particular reason to
7593 prefer setjmp+longjmp.
7595 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7597 Fix minor problem found by static checking.
7598 * buffer.c (Fdelete_all_overlays): Return nil.
7600 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7602 * buffer.c (Fdelete_all_overlays): New function.
7604 2012-09-03 Chong Yidong <cyd@gnu.org>
7606 * gtkutil.c: Add extern decl for Qxft.
7608 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
7610 * emacs.c, eval.c: Use bool for boolean.
7611 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
7612 (malloc_using_checking) [DOUG_LEA_MALLOC]:
7613 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
7614 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)

7617 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
7618 (maybe_call_debugger, Fbacktrace):
7619 * process.c (read_process_output, exec_sentinel):
7620 Use bool for booleans.
7621 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
7622 All callers changed.
7623 * eval.c (interactive_p): Omit always-true boolean argument
7624 EXCLUDE_SUBRS_P. All callers changed.
7625 * dispextern.h, lisp.h: Reflect above API changes.
7626 * firstfile.c (dummy): Use the address of 'main', whose signature
7627 won't change, instead of the address of 'initialize', whose
7628 signature just changed from int to bool.
7629 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7630 * msdos.c (fatal_error_in_progress): ... from here.
7631 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7633 (redisplay_internal, unwind_redisplay): Simply clear
7634 REDISPLAYING_P when unwinding, instead of saving its previous,
7635 always-false value and then restoring it.
7637 Clean up some extern decls.
7638 Mostly, this hoists extern decls out of .c files and into .h files.
7639 That way, we're more likely to catch errors if the interfaces change.
7640 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7641 declare xg_mark_data.
7642 * dispextern.h (x_frame_parm_handlers):
7644 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
7645 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
7646 (Qultra_bold, Qoblique, Qitalic):
7647 Move extern decl here from .c file.
7648 * alloc.c (xg_mark_data) [USE_GTK]:
7650 * eval.c (Qlexical_binding):
7651 * fns.c (time) [!HAVE_UNISTD_H]:

7657 * process.c (QCfamily, QCfilter):
7658 * widget.c (free_frame_faces):
7659 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
7660 * xfont.c (x_clear_errors):
7661 * xterm.c (x_frame_parm_handlers):
7662 Remove now-redundant extern decls.
7663 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7664 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7666 * xfaces.c: Remove unnecessary static decls.
7667 * xterm.c (updating_frame): Remove decl of nonexistent object.
7669 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7670 when building globals.h, as the objects that are not built on
7671 this host are not needed to compile C files on this host.
7673 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
7675 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
7677 * frame.h: Add missing prototype for x_wm_set_size_hint.
7679 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

7683 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
7684 (Fsubstitute_command_keys):

7689 (make_buffer_string, make_buffer_string_both)
7690 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

7703 * keyboard.c (decode_timer):
7704 Use bool for boolean.
7705 * intervals.h, lisp.h, systime.h: Reflect above API changes.
7706 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
7708 2012-09-02 Chong Yidong <cyd@gnu.org>
7710 * keymap.c (push_key_description): Print M-TAB as C-M-i
7713 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
7715 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
7716 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
7717 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

7721 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
7723 2012-09-01 Eli Zaretskii <eliz@gnu.org>
7725 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7726 more than one grapheme cluster passed to the shaper: compute the
7727 offset adjustment values separately for each cluster. (Bug#11860)
7729 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7730 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7731 about implicit conversions from integer to pointer.
7733 2012-09-01 Daniel Colascione <dancol@dancol.org>
7735 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7736 system used too early.
7738 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
7740 Better seed support for (random).
7741 * emacs.c (main): Call init_random.
7742 * fns.c (Frandom): Set the seed from a string argument, if given.
7743 Remove long-obsolete Gentzel cruft.
7744 * lisp.h, sysdep.c (seed_random): Now takes address and size, not long.
7745 (init_random): New function.
7747 2012-09-01 Daniel Colascione <dancol@dancol.org>
7749 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
7750 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
7751 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,

7845 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
7846 does not become zero (Bug#12234).

7876 (timeout_handler:): Set timer_fired to YES.
7877 (runDialogAt:): Set timer_fired to NO.
7878 Handle click on close button as quit.
7880 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7881 Add window_closed and button_values. Add void as return value for
7882 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7883 Add process_dialog as new member.
7885 2012-08-28 Eli Zaretskii <eliz@gnu.org>
7887 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
7888 is not one of the heaps we manage. (Bug#12242)
7890 2012-08-28 Glenn Morris <rgm@gnu.org>

7960 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7962 * window.c (Fset_window_configuration): Revert first part of
7965 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
7967 * nsterm.h (NSPanel): New class variable dialog_return.

7970 Initialize dialog_return.
7971 (windowShouldClose:): Use stop instead of stopModalWithCode.
7972 (clicked:): Ditto, and also set dialog_return (Bug#12258).
7973 (timeout_handler:): Use stop instead of abortModal. Send a dummy

8023 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
8024 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
8025 not a boolean 'int', since callers never look at the return value.

8028 (emacs_mule_string_char): Remove unused extern decls.
8029 (struct iso_2022_spec, struct coding_system):

8035 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8037 Fix spare memory change (Bug#12286).
8038 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
8039 (valid_lisp_object_p): Likewise.
8041 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8043 * window.c (Fset_window_configuration): Record any window's old
8044 buffer if it's replaced (see Bug#8789). If the new current
8045 buffer doesn't appear in the selected window, go to its old
8048 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8050 Special MEM_TYPE_SPARE to denote reserved memory.
8051 * alloc.c (enum mem_type): New memory type.
8052 (refill_memory_reserve): Use new type for spare memory.
8053 This prevents live_cons_p and live_string_p from incorrect

8056 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
8059 * Makefile.in (.PHONY): versioclean -> versionclean.

8063 * window.c (Qwindow_valid_p, decode_valid_window):
8064 Now static, not extern.
8065 * data.c (Qinterval): Remove; unused.

8082 (map_sub_char_table):
8083 Use bool for boolean.
8084 * character.c (str_to_unibyte): Omit last boolean argument; it was
8085 always 0. All callers changed.
8086 * character.h, charset.h: Adjust to match previous changes.
8087 * character.h (char_printable_p): Remove decl of nonexistent function.
8088 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
8089 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
8090 are all boolean, so make them single-bit bitfields.
8092 * lisp.h (ASET): Remove attempt to detect side effects.
8093 It was meant to be temporary and it often doesn't work,
8094 because when IDX has side effects the behavior of IDX==IDX
8095 is undefined. See Stefan Monnier in
8096 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
8098 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
8100 * lisp.h (functionp): New function (extracted from Ffunctionp).
8101 (FUNCTIONP): Use it.
8102 * eval.c (Ffunctionp): Use it.
8104 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8106 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
8107 as that's faster and simpler than static storage. Don't bother
8108 with the g_main_context_query overhead if g_main_context_pending
8109 says no events are pending.
8110 (gfds, gfds_size): Remove these static vars.
8111 (xgselect_initialize): Remove; no longer needed.
8112 All uses and decls removed.
8114 * emacs.c (fatal_error_signal_hook): Remove.
8115 All uses removed. This leftover from old code was always 0.
8117 * casefiddle.c, casetab.c, category.c: Use bool for boolean.

8130 On assertion failure, print backtrace if available.
8131 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.

8141 * lisp.h (USE_SAFE_ALLOCA):
8142 Use bool for booleans, instead of int.
8143 * lisp.h, process.h: Adjust prototypes to match above changes.
8144 * callint.c (Fcall_interactively): Don't assume the mark's
8145 offset fits in 'int'.
8147 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>

8156 (mmap_enlarge, mmap_set_vars):
8157 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
8158 Use bool for booleans, instead of int.
8159 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
8160 since the 1-or-0 return value is always ignored anyway.
8161 (mmap_initialized_p):
8162 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
8163 * buffer.h, lisp.h: Adjust prototypes to match above changes.
8165 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8167 * bidi.c: Use bool for boolean.
8168 This is a bit more readable, and makes the text segment of bidi.o
8169 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
8170 Presumably it's faster too.
8171 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

8195 compile time tests instead of run time tests on systems that do
8197 (FRAME_MAC_P): Remove leftover from deleted code.

8200 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
8202 * nsterm.m (insertText:): Don't clear modifiers if code is space.
8204 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
8206 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
8207 Otherwise, the compiler complains about (A?B:C) where B is void
8208 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
8209 (fontset_add): Return void, for FONTSET_ADD.
8211 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8213 * alloc.c: Use bool for booleans.
8214 (gc_in_progress, abort_on_gc)
8215 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8216 (dont_register_blocks) [GC_MALLOC_CHECK]:
8217 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
8218 (check_string_bytes, make_specified_string, memory_full)
8219 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
8220 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
8221 (mark_stack, valid_pointer_p, make_pure_string)
8222 (Fgarbage_collect, survives_gc_p, gc_sweep):
8223 Use bool for booleans, instead of int.
8224 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8225 Remove unused local.
8226 * alloc.c (PURE_POINTER_P):
8227 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
8228 * editfns.c (Fformat):
8229 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
8231 * fns.c (sweep_weak_table):
8232 * lisp.h (suppress_checking, push_message, survives_gc_p)
8233 (make_pure_string, gc_in_progress, abort_on_gc):
8234 * lread.c (readchar, read1):
8235 * print.c (Fprin1_to_string):
8236 * xdisp.c (push_message):
8237 Use bool for booleans affected directly or indirectly by
8240 Make recently-introduced setters macros.
8241 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
8242 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
8243 (set_fontset_default, set_fontset_fallback): Rename from their
8244 upper-case counterparts, and make them functions rather than macros.
8245 This is more consistent with the other recently-introduced setters.
8246 These don't need to be inline, since they're local.
8248 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
8250 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in

8253 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8255 * lisp.h (vcopy): Use memcpy rather than our own loop.
8256 This fixes a performance regression introduced by the recent
8257 addition of vcopy. This means 'vcopy' will need to be modified
8258 for a copying collector, but that's OK. Also, tighten the
8259 checking in the assertion.
8261 2012-08-21 Eli Zaretskii <eliz@gnu.org>
8263 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
8264 components for RTL text (Bug#11860). Adjust X-OFFSET of each
8265 non-base glyph for the width of the base character, according to
8266 what x_draw_composite_glyph_string_foreground expects.
8267 Generate WADJUST value according to composition_gstring_width's
8268 expectations, to produce correct width of the composed character.
8269 Reverse the sign of the DU offset produced by ScriptPlace.
8271 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8273 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
8275 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8277 Avoid direct writes to contents member of struct Lisp_Vector.
8278 * lisp.h (vcopy): New function to copy data into vector.

8292 the position of its buffer's point.
8293 (Fset_window_point): For the selected window always go in its
8294 buffer to the specified position.
8296 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8298 Setter macros for fontsets.
8299 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
8300 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
8301 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8304 2012-08-20 Glenn Morris <rgm@gnu.org>
8306 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8307 Don't assume that `ln -f' works.
8309 2012-08-20 Eli Zaretskii <eliz@gnu.org>
8311 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8312 and later about non-assignments with no effect. See discussion at
8313 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
8316 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8318 Inline setter functions for Lisp_Objects slots of struct specbinding.
8319 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
8322 2012-08-20 Martin Rudalics <rudalics@gmx.at>
8324 * window.c (select_window): Always make selected window's buffer
8327 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8329 Use AREF and ASET for docstrings of category tables.
8330 * category.h (CATEGORY_DOCSTRING): Use AREF.
8331 (SET_CATEGORY_DOCSTRING): Use ASET.
8332 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
8334 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8336 Inline setter functions for hash table members.
8337 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8338 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8339 (set_hash_key_and_value, set_hash_index, set_hash_next)
8340 (set_hash_hash): New functions.
8341 * charset.c, fns.c: Adjust users.
8343 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8345 Inline getter and setter functions for per-buffer values.

8349 * buffer.c, data.c: Adjust users.
8351 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
8353 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8355 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8357 Rely on <config.h> + <unistd.h> to declare 'environ',
8358 as gnulib does this if the system doesn't.
8359 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8360 Remove declaration. MS-Windows declares it on stdlib.h which is
8361 included by conf_post.h.
8362 * emacs.c (environ) [DOUG_LEA_MALLOC]:
8363 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
8364 * vm-limit.c: Include <unistd.h>, for 'environ'.
8366 * unexaix.c, unexcoff.c: Include "mem-limits.h".
8367 (start_of_data): Remove decl; mem-limits.h provides it.
8369 * xdisp.c (handle_invisible_prop): Make it a bit faster
8370 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8372 2012-08-19 Chong Yidong <cyd@gnu.org>
8374 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
8377 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>

8382 * data.c (set_internal): Don't use set_blv_found.
8383 (Fkill_local_variable): Likewise.
8385 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
8387 * nsfont.m (ns_ascii_average_width): Ensure the string
8388 ascii_printable is initialized with a null-terminated character
8389 array. Otherwise, it can contain undesired extra characters.
8391 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8393 port new setting code to Sun C 5.8 2005/10/13
8394 * chartab.c, lisp.h (char_table_set, char_table_set_range):
8395 Return void, not Lisp_Object. Otherwise, the compiler
8396 complains about (A?B:C) where B is void and C is Lisp_Object
8397 when compiling CHAR_TABLE_SET, due to the recent change to
8398 the API of sub_char_table_set_contents.
8400 2012-08-18 Chong Yidong <cyd@gnu.org>
8402 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE

8558 The old version was confusing because it used the same name
8559 'parent' for two different things.

8572 font spec, make the font's attributes take precedence over
8573 directly-specified attributes.
8574 (merge_face_ref): Recognize :font.
8576 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

8623 Use C-locale tests instead of locale-specific tests for character
8624 types, since we want the ASCII interpretation here, not the
8625 interpretation suitable for whatever happens to be the current locale.

8629 Consistently check windows for validity/liveness

9230 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
9231 * w32.c (init_environment): Change the default values of many
9232 environment variables in dflt_envvars[] to NULL, to avoid pushing
9233 them into environment when they were not already defined.
9234 Remove the code that deletes site-lisp subdirectories from the default
9235 value of EMACSLOADPATH, as it is no longer needed.
9236 (check_windows_init_file): Now external, not static.
9237 Use Vload_path as is, without adding anything, as this function is now
9238 called when Vload_path is already set up.
9240 * w32.h (check_windows_init_file): Add prototype.
9242 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

9249 installation tree, as appropriate.
9251 * callproc.c (init_callproc_1): Call decode_env_path instead of
9252 doing its equivalent by hand.

9254 the code that sets Vexec_path run on MS-Windows.
9256 * lread.c (init_lread): Add comments to #ifdef's.
9258 * msdos.c (dos_set_window_size, IT_update_begin)

9270 Remove unnecessary casts involving pointers.
9271 These casts are no longer needed now that we assume C89 or later,

9285 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
9286 Remove unnecessary pointer casts.
9287 * alloc.c (record_xmalloc): New function.
9288 * lisp.h (record_xmalloc): New decl.
9289 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
9290 more like a function. This is because the pointer cast is not
9291 needed. All uses changed.
9292 * print.c (print_string, print_error_message): Avoid length recalc.
9294 Improve fix for macroexp crash with debugging (Bug#12118).
9295 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
9296 ARRAY_MARK_FLAG when checking subscripts, because ASET is
9297 not supposed to be invoked from the garbage collector.
9298 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
9299 (gc_aset): New function, which is like ASET but can be
9300 used in the garbage collector.
9301 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

9316 headers (most versions of MinGW w32api don't).
9317 (get_security_info, create_symbolic_link)
9318 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

9325 have the required privileges.
9326 (get_file_security_desc_by_name): Rename from

9329 with addition of handling of symlinks and support for 'lstat'.
9330 If possible, get file's attributes and security information by
9331 handle, not by name. Produce S_IFLNK bit for symlinks, when
9332 called from 'lstat'.
9333 (stat, lstat): New functions, call 'stat_worker'.
9334 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9335 symlinks when the underlying filesystem supports them.
9337 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
9339 Fix macroexp crash on Windows with debugging (Bug#12118).
9340 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9341 checking subscripts; problem introduced with the recent
9342 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9343 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9344 since it's used in non-static inline functions now.
9346 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9347 Don't assume buffer size fits in 'int'. Remove unused local.

9364 * category.c (CATEGORY_INLINE):
9365 * character.c (CHARACTER_INLINE):
9366 * charset.c (CHARSET_INLINE):
9367 * composite.c (COMPOSITE_INLINE):
9368 * dispnew.c (DISPEXTERN_INLINE):
9369 * sysdep.c (SYSTIME_INLINE):
9370 Define to EXTERN_INLINE, so that the corresponding functions
9371 are compiled into code.
9372 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
9373 (INLINE_HEADER_END): New macros.
9374 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9394 hard-coding the path separator.
9396 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9398 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9399 This how ASET and AREF are supposed to work, and makes
9400 it easier to think about future improvements. See
9401 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
9402 * charset.h (set_charset_attr): New function.

9894 the fix for 12036 would have avoided some of the problems noted in
9895 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9896 would have been more obvious.

9906 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9907 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9908 not be usable in #if. This simplifies things.
9910 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9912 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

9917 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9918 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9919 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9920 Adjust to changes in lisp.h and emacs.c, by using

9923 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

9927 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9928 instead of gdb_array_mark_flag.
9929 (xboolvector): Get size from $->size, not $->header.size.
9930 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9931 (xreload, hook-run, hookpost-run): Remove.
9932 * emacs.c: Include <verify.h>.
9933 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9934 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9936 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9937 (gdb_USE_LSB_TAG): New enum constants.
9938 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9939 Also define these as enum constants, so they're visible to GDB.

9941 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

9946 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9947 more convenient now. All uses changed.
9948 (VALMASK) [USE_LSB_TAG]: Also define in this case.

9951 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

10825 (menu_separator_name_p):

10833 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10834 * nsterm.m (ns_term_init):
10835 Avoid the need for strncpy, by using build_string or
10836 make_unibyte_string directly. Use dtoastr, not snprintf.
10837 * process.c (Fmake_network_process): Diagnose service names that
10838 are too long, rather than silently truncating them or creating
10839 non-null-terminated names.
10840 (Fnetwork_interface_info): Likewise, for interface names.
10841 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10842 Prefer sprintf to strncat.

10853 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
10854 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
10855 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10856 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
10857 where argument type is known to be a Lisp_Cons.
10859 2012-07-10 Tom Tromey <tromey@redhat.com>
10861 * bytecode.c (BYTE_CODE_THREADED): New macro.

10871 (build_pure_c_string): New function, defined as static inline. This
10872 provides a better opportunity to optimize away calls to strlen when
10873 the function is called with compile-time constant argument.
10874 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10875 argument, adjust users accordingly. Use build_pure_c_string where
10877 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
10878 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10879 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
10881 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10883 Avoid calls to strlen in miscellaneous functions.
10884 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
10885 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
10886 * lread.c (openp): Likewise.
10888 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10890 Avoid calls to strlen in path processing functions.
10891 * fileio.c (file_name_as_directory): Add comment. Change to add
10892 srclen argument and return the length of result. Adjust users
10894 (directory_file_name): Fix comment. Change to add srclen argument,
10895 swap 1st and 2nd arguments to obey the common convention.
10896 Adjust users accordingly.
10897 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
10899 2012-07-10 Glenn Morris <rgm@gnu.org>

10902 Move PENDING_OUTPUT_COUNT definition to configure.
10904 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
10905 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
10906 * s/gnu.h (DATA_START): Move definitions to configure.
10908 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10909 We include usg5-4-common.h, which defines them both.
10911 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10912 O_RDONLY already includes it).
10914 Stop ns builds setting the EMACSLOADPATH environment variable.
10915 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10916 Now it does not set EMACSLOADPATH, just returns the load-path string.
10917 * nsterm.h: Update accordingly.
10918 * lread.c [HAVE_NS]: Include nsterm.h.
10919 (init_lread) [HAVE_NS]: Use ns_load_path.
10920 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10922 2012-07-09 Glenn Morris <rgm@gnu.org>
10924 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10925 since the included bsd-common.h does so.
10927 Stop ns builds setting the EMACSPATH environment variable.
10928 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10929 (ns_init_paths): Do not set EMACSPATH.
10930 * nsterm.h (ns_exec_path): Add it.
10931 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10934 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10936 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10938 * process.c (wait_reading_process_output): 'waitchannels' was unset
10939 when read_kbd || !NILP (wait_for_cell); fix this.
10941 Add GCC-style 'const' attribute to functions that can use it.
10942 * character.h (char_resolve_modifier_mask):
10943 * keyboard.h (make_ctrl_char):
10944 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10945 (init_character_once, next_almost_prime, init_fns, init_image)
10946 (flush_pending_output, init_sound):
10947 * mem-limits.h (start_of_data):

10953 Add decls with ATTRIBUTE_CONST.
10955 Minor improvements to make_formatted_string.
10956 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10957 where int is good enough, as vsprintf returns an int.
10958 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10960 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10962 Use make_formatted_string to avoid double length calculation.
10963 * lisp.h (make_formatted_string): New prototype.
10964 * alloc.c (make_formatted_string): New function.

10985 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10987 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10989 Move marker debugging code under MARKER_DEBUG.
10990 * marker.c (MARKER_DEBUG): Move marker debugging code under
10991 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10992 for bootstrap with --enable-checking (~3x slowdown reported
10993 by Juanma Barranquero <lekktu@gmail.com>).
10994 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10996 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10998 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10999 See <http://bugs.gnu.org/11825#29>.
11001 2012-07-08 Eli Zaretskii <eliz@gnu.org>
11003 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
11004 has no font, use the frame's font. (Bug#11813)
11005 (display_line): Add commentary about displaying truncation glyphs
11007 (produce_special_glyphs): Move here from term.c.
11009 * term.c (produce_special_glyphs): Move to xdisp.c.
11011 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
11014 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
11016 * xdisp.c (display_line): Avoid warning about implicit declaration
11019 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
11021 * lisp.h: Remove empty conditional.
11023 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11025 * lread.c (load_path_check): Now static.
11027 Fix some minor --with-ns problems found by static checking.
11028 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
11029 (x_set_font) [!HAVE_X_WINDOWS]:
11030 * image.c (xpm_load_image) [HAVE_NS]:
11031 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
11032 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
11033 Remove unused local.
11034 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
11035 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
11036 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
11037 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
11038 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
11039 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
11040 Fix pointer signedness problem.
11041 * xfaces.c (FRAME_X_FONT_TABLE):
11042 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
11044 2012-07-07 Glenn Morris <rgm@gnu.org>
11046 * lread.c (load_path_check): New function, split from init_lread.
11047 (init_lread): Reorganize. Motivation:
11048 If EMACSLOADPATH is set, check/warn about that rather than the
11049 defaults, which we are not going to use. Hence we can remove
11050 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
11051 Don't warn if site-lisp directories are missing.
11052 If not installed, start from a blank load-path, since
11053 PATH_LOADSEARCH refers to the eventual installation directories.
11055 2012-07-07 Eli Zaretskii <eliz@gnu.org>
11057 Support truncation and continuation glyphs on GUI frames, when
11058 fringes are disabled. (Bug#11832)
11059 * xdisp.c (init_iterator): Get dimensions of truncation and
11060 continuation glyphs even if on GUI frames.
11061 Adjust it->last_visible_x on GUI frames when the left or right fringes,
11062 or both, are absent.
11063 (start_display, move_it_in_display_line_to): Handle the case of a
11064 GUI frame without a fringe to display continuation or truncation
11066 (insert_left_trunc_glyphs): Support GUI frames: make sure
11067 truncation glyphs overwrite enough glyphs from the current line to
11068 have sufficient space in pixels.
11069 (display_line): Support truncation and continuation glyphs on GUI
11070 frames. If some spare pixels are left on the line after inserting
11071 the truncation glyphs, fill that space with a stretch glyph of a
11072 suitably computed width.
11074 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
11075 produce_glyphs, to support GUI sessions.
11077 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11079 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
11081 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
11083 Do not require float-time's arg to fit in time_t (Bug#11825).
11084 This works better on hosts where time_t is unsigned, and where
11085 float-time is applied to the (negative) difference between two times.
11086 * editfns.c (decode_time_components): Last arg is now double *,
11087 not int *, and means to store all the result as a double, without
11088 worrying about whether the seconds part fits in time_t.
11089 All callers changed.
11090 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
11091 All callers changed.
11092 (Ffloat_time): Do not fail merely because the specified time falls
11093 outside of time_t range.
11095 2012-07-07 Glenn Morris <rgm@gnu.org>
11097 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
11098 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
11099 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
11101 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
11103 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
11104 Update dependencies.
11106 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
11108 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

11112 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
11113 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
11114 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
11115 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
11117 * xfont.c (compare_font_names): Redo to omit the need for casts.
11119 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
11121 * xfns.c (Fx_change_window_property): Doc fix.
11122 * w32fns.c (Fx_change_window_property): Doc fix.
11124 * w32fns.c (Fx_window_property): Accept the same arguments as the
11125 X Windows version. Doc fix.
11126 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
11128 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
11129 Eli Zaretskii <eliz@gnu.org>
11131 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
11132 Windows-specific code from nt/config.nt moved here.
11133 Obsolete settings removed.
11135 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11137 * process.c: Avoid unnecessary calls to gettime.
11138 (wait_reading_process_output): Don't get the time of day
11139 when gobbling data immediately and not waiting, as there's no need
11140 for it in that case. This removes a FIXME.
11142 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
11144 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
11145 is defined (Bug#11768).
11147 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11149 Fix marker debugging code.
11150 * marker.c (byte_char_debug_check): Do not perform the check
11151 if buffer is not multibyte.
11152 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11153 Call byte_char_debug_check with correct arguments.
11155 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11157 Compile marker debugging code only if ENABLE_CHECKING is defined.
11158 * marker.c (byte_char_debug_check, count_markers):
11159 Use only if ENABLE_CHECKING is defined.
11160 (byte_debug_flag): Remove.
11161 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11162 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
11164 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11166 Avoid code repetition in marker-related functions.
11167 * marker.c (attach_marker): New function.
11168 (Fset_marker, set_marker_restricted, set_marker_both)
11169 (set_marker_restricted_both): Use it.

11171 Consistently rename charno to charpos.
11172 (marker_position): Add eassert.
11173 (marker_byte_position): Convert to eassert.
11175 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11177 Simplify list operations in unchain_overlay and unchain_marker.
11178 * buffer.c (unchain_overlay): Simplify. Add comment.
11179 * marker.c (unchain_marker): Simplify. Fix comments.

11186 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
11187 * composite.c (autocmp_chars): Likewise.
11188 * editfns.c (buildmark): Remove.
11189 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
11190 (save_restriction_save): Use build_marker.
11191 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
11192 * window.c (save_window_save): Likewise.
11194 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11196 Do not use Fdelete_overlay in delete_all_overlays
11197 to avoid redundant calls to unchain_overlay.
11198 * buffer.c (drop_overlay): New function.
11199 (delete_all_overlays, Fdelete_overlay): Use it.
11200 * minibuf.c (get_minibuffer): Fix comment.
11202 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11204 Port to OpenBSD 5.1 amd64.
11205 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
11206 This is needed for OpenBSD, and should be harmless on all BSD systems.
11207 Also, include <sys/sysctl.h>, as it should be available on all
11208 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
11209 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
11210 use p_pid member, not kp_proc.pid.
11212 2012-07-06 Glenn Morris <rgm@gnu.org>
11214 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
11216 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11218 More xmalloc and related cleanup.
11219 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
11220 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
11221 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
11222 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
11223 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
11224 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
11225 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
11226 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
11227 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
11229 Omit needless casts involving void * pointers and allocation.
11230 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
11231 as the former is more robust if P's type is changed.
11232 Prefer xzalloc to xmalloc + memset 0.
11233 Simplify malloc-or-realloc to realloc.
11234 Don't worry about xmalloc returning a null pointer.
11235 Prefer xstrdup to xmalloc + strcpy.
11236 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
11238 * keyboard.c (apply_modifiers_uncached): Prefer local array to
11239 alloca of a constant.

11243 * xdisp.c (display_line): Fix horizontal pixel coordinates when
11244 hscroll is larger than the line width. Fixes long and futile
11245 looping inside extend_face_to_end_of_line (on a TTY) producing
11246 glyphs that are not needed and thrown away.
11248 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
11250 * marker.c (set_marker_restricted_both): Simplify by using
11253 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

11259 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
11260 not defined (Bug#11768).
11261 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
11262 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)

11270 (xg_tool_item_stale_p): Call is_box_type.
11271 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
11272 with default display (Bug#11768).
11274 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11276 * xdisp.c (window_hscroll_limited): New function.
11277 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
11278 coordinates when window's hscroll is set to insanely large
11279 values. (Bug#11857)
11281 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

11344 * fileio.c (time_error_value): Check the right error number.
11345 Problem reported by Troels Nielsen in
11346 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11348 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11350 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11351 This should be fixed in a better way; see Eli Zaretskii in
11352 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11353 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11355 * fileio.c (time_error_value): Rename from special_mtime.
11356 The old name's problems were noted by Eli Zaretskii in
11357 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11359 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11360 This variable's comment says Emacs needs at least one GDB-visible
11361 symbol of type enum pvec_type, to work around GDB problems.
11362 The symbol's value doesn't matter.
11364 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11365 that causes compilation to fail on pre-C99 compilers.
11367 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11369 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
11370 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
11372 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11374 * buffer.c (init_buffer_once): Fix initialization of
11375 headers for buffer_defaults and buffer_local_symbols.
11376 Reported by Juanma Barranquero <lekktu@gmail.com>.
11378 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11380 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
11381 * lisp.h (enum pvec_type): Use fewer bits.
11382 (PSEUDOVECTOR_SIZE_BITS): New constant.
11383 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
11384 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
11385 change in pvec_type.
11386 (PSEUDOVECTOR_TYPEP): New macro.
11387 (TYPED_PSEUDOVECTORP): Use it.
11388 * fns.c (internal_equal): Adapt code to extract pvectype.
11389 * emacs.c (gdb_pvec_type): Update type.
11390 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
11391 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
11392 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
11393 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11394 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11395 abusing vector->header.next.nbytes.
11396 (live_vector_p): Use PVEC_TYPE.
11397 (mark_object): Adapt code to extract pvectype. Use switch.
11399 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11401 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11402 Tighten new eassert a bit.
11404 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11406 Fix compilation with --enable-gcc-warnings and -O1
11407 optimization level.
11408 * doprnt.c (doprnt): Change type of tem to int, initialize
11409 to avoid compiler warning. Add eassert.
11410 * search.c (simple_search): Initialize match_byte to avoid
11411 compiler warning. Add eassert.
11413 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11415 Avoid weird behavior with large horizontal scrolls.
11416 Without this change, for example, large hscroll values would
11417 mess up Emacs's display on Fedora 15 x86, presumably due to
11418 overflows in int calculations in the display code.
11419 Also, if buffers had long lines, Emacs would freeze.
11420 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11421 (set_window_hscroll): New function, containing the old guts of
11422 Fset_window_hscroll. Return the clipped value.
11423 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11424 This avoids the need to check against PTRDIFF_MAX.
11426 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11428 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11430 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11432 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11434 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11435 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11436 since GCC 4.4.6 issues a bogus warning for them.
11438 Fix bugs in file timestamp newness comparisons.
11439 * fileio.c (Ffile_newer_than_file_p):
11440 * lread.c (Fload): Use full timestamp resolution of files,
11441 not just the 1-second resolution, so that files that are only
11442 slightly newer still count as newer.
11443 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11444 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11446 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11448 * fileio.c: Improve handling of file time marker. (Bug#11852)
11449 (special_mtime): New function.
11450 (Finsert_file_contents, Fverify_visited_file_modtime):
11451 Use it to set special mtime values consistently.
11453 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11455 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11456 marker for non-existing file. (Bug#11852)
11458 2012-07-03 Glenn Morris <rgm@gnu.org>
11460 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11461 and did not make it into globals.h).
11463 2012-07-03 Tom Tromey <tromey@redhat.com>
11465 * window.c (Fset_window_margins, Fset_window_fringes)
11466 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
11467 * textprop.c (Fprevious_property_change): No longer static.
11468 * syntax.c (Fsyntax_table_p): No longer static.
11469 * process.c (Fget_process, Fprocess_datagram_address): No longer

11492 * font.h: Remove EXFUNs.
11493 * dosfns.c (system_process_attributes): Remove EXFUN.
11494 * keymap.h: Remove EXFUNs.
11495 * lisp.h: Remove EXFUNs.
11496 * w32term.h: Remove EXFUNs.
11497 * window.h: Remove EXFUNs.
11498 * xsettings.h: Remove EXFUN.
11499 * xterm.h: Remove EXFUN.
11501 2012-07-03 Glenn Morris <rgm@gnu.org>
11503 * lisp.h (Frandom): Make it visible to C.
11504 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11505 buffer for invisible buffers. (Bug#1229)
11507 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11509 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11510 values which aren't power of 2.
11511 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11512 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11515 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11517 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11519 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11521 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11523 * alloc.c (allocate_vector_block): Remove redundant
11524 calls to mallopt if DOUG_LEA_MALLOC is defined.
11525 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11526 avoid calls to mallopt if zero_vector is returned.
11528 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11530 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11531 is enabled, avoid dereferencing NULL current_sblock if
11534 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11536 Cleanup basic buffer management.
11537 * buffer.h (struct buffer): Change layout to use generic vector
11538 marking code. Fix some comments. Change type of 'clip_changed'
11539 to bitfield. Remove unused #ifndef old.
11540 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11541 (GET_OVERLAYS_AT): Fix indentation.
11542 (for_each_per_buffer_object_at): New macro.
11543 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

11547 struct buffer. Fix comment.
11548 (mark_overlay): New function.
11549 (mark_buffer): Use it. Use mark_vectorlike to mark normal

11551 (mark_object): Use it. Adjust marking of misc objects
11552 and related comments.
11554 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11556 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11557 wrapper that is not needed because the wrapped code is a no-op (zero
11558 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11559 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11561 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11563 * alloc.c (mark_buffer): Simplify. Remove prototype.
11564 (mark_object): Add comment. Reorganize marking of vector-like
11565 objects. Use CHECK_LIVE for all vector-like objects except buffers
11566 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11567 Avoid redundant calls to mark_vectorlike for bool vectors.
11569 2012-06-30 Glenn Morris <rgm@gnu.org>
11571 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11573 * epaths.in (PATH_SITELOADSEARCH): New.
11574 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11575 This is rather than relying on --enable-locallisppath elements
11576 having "site-lisp" in their names. (Bug#10208#25, 11658)
11578 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11580 * w32proc.c (sys_select): Accept and ignore one more argument.
11582 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11584 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11585 (pselect) [!MS_DOS]: Redirect to sys_select.
11587 * sysdep.c: Don't include dos.h and dosfns.h.
11589 * process.c (sys_select):
11590 * msdos.c (sys_select): Accept one more argument and ignore it.
11592 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11593 adapt data types and code to that.
11596 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11597 which clashes with the gnulib function of the same name.
11599 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11601 * font.c (font_style_to_value, font_style_symbolic)
11602 (font_prop_validate_style): Add type checks for values in
11605 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11607 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11610 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11612 * xdisp.c (try_window_id): Undo last change.
11614 * w32.c (getwd): Adjust commentary about startup_dir.
11615 (init_environment): Always call sys_access, even in non-MSVC
11616 builds. Don't chdir to the directory of the Emacs executable.
11617 This undoes code from 1997 which was justified by the need to
11618 "avoid conflicts when removing and renaming directories". But its
11619 downside was that every relative file name was being interpreted
11620 relative to the directory of the Emacs executable, which can never
11621 be TRT. In particular, it broke sys_access when called with
11622 relative file names.
11623 (sys_access): Map GetLastError to errno.
11625 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11627 * window.h (struct window): Change type of 'fringes_outside_margins'
11628 to bitfield. Fix comment. Adjust users accordingly.
11629 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
11631 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11634 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11636 * gnutls.c (emacs_gnutls_handshake):
11637 Add QUIT to make the loop interruptible.
11639 2012-06-29 Glenn Morris <rgm@gnu.org>
11641 * charset.c (init_charset): Make lack of etc/charsets fatal.
11643 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11645 * editfns.c (region_limit): Fix type mismatch.
11647 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11649 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11650 undefined. Convert from xassert to eassert.
11651 * nsmenu.m: Convert from xassert to eassert.
11652 * nsterm.m: Likewise.
11654 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
11656 * editfns.c (region_limit): Clip to narrowing (bug#11770).
11658 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11660 Avoid integer overflow on scroll-left and scroll-right.
11661 * window.c (HSCROLL_MAX): New macro.
11662 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11663 overflow when requested scroll falls outside ptrdiff_t range.
11665 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11667 * window.h (struct window): Change type of 'hscroll',
11668 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11669 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11670 Adjust users accordingly.
11671 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11672 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11673 from EMACS_INT to ptrdiff_t.
11674 (make_window): Omit redundant initialization.
11676 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
11678 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
11680 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11682 * window.h (struct window): Change type of 'use_time' and
11683 'sequence_number' from Lisp_Object to int.

11691 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
11692 enabled with --enable-checking=[all,glyphs] configure option.
11693 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11694 adjust comments accordingly.

11817 Use sprintf return value instead of invoking strlen on result.
11818 In the old days this wasn't portable, since some sprintf
11819 implementations returned char *. But they died out years ago and
11820 Emacs already assumes sprintf returns int.
11821 Similarly for float_to_string.
11822 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

11830 Use sprintf or float_to_string result to avoid need to call strlen.
11831 * data.c (Fnumber_to_string):
11832 Use make_unibyte_string, since the string must be ASCII.
11833 * lisp.h, print.c (float_to_string): Now returns int length.
11834 * term.c (produce_glyphless_glyph):
11835 Use sprintf result rather than recomputing it.
11837 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

11870 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

11875 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string

11939 This improves on the previous patch, which introduced a bug
11940 when time_t is unsigned and as wide as intmax_t.
11941 See <http://bugs.gnu.org/9000#51>.

11972 language ID in the event parameters.
11974 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11975 event.code, not the obscure "character set ID".
11977 2012-06-23 Chong Yidong <cyd@gnu.org>

12006 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
12008 Support higher-resolution time stamps (Bug#9000).
12009 The time stamps are only nanosecond-resolution at the C level,
12010 since that's the best that any real-world system supports now.
12011 But they are picosecond-resolution at the Lisp level, as that's
12012 easy, and leaves room for future OS improvements.
12014 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
12017 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
12018 Don't get current time unless it's needed.
12020 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
12021 now provides it if it's absent.
12022 (start_atimer): Port to higher-res time stamps.
12023 Check for time stamp overflow. Don't get current time more
12024 often than is needed.
12026 * buffer.h (struct buffer): Buffer modtime now has high resolution.
12027 Include systime.h, not time.h.
12028 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
12030 * dired.c: Include stat-time.h.
12031 (Ffile-attributes): File times now have higher resolution.
12033 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
12034 (struct image): Timestamp now has higher resolution.
12036 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
12037 has at least microseconds now. All uses removed.
12038 (update_frame, update_single_window, update_window, update_frame_1)
12039 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
12040 (duration_to_sec_usec): Remove; no longer needed.

12048 (decode_time_components, lisp_seconds_argument): New functions.
12049 (make_time): Now static.
12050 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
12051 Report an error if the time is invalid, rather than having the caller
12054 * fileio.c: Include <stat-time.h>
12055 (Fcopy_file): Copy higher-resolution time stamps.
12056 Prefer to set the time stamp via a file descriptor if that works.
12057 (Fset_file_times, Finsert_file_contents, Fwrite_region)
12058 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
12059 (Fvisited_file_modtime, Fset_visited_file_modtime):
12060 Support higher-resolution time stamps.
12062 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
12064 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
12066 * image.c (prepare_image_for_display, clear_image_cache)
12067 (lookup_image): Port to higer-resolution time stamps.
12069 * keyboard.c (start_polling, bind_polling_period):
12070 Check for time stamp overflow.
12071 (read_char, kbd_buffer_get_event, timer_start_idle)
12072 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
12073 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
12074 Port to higher-resolution time stamps. Do not assume time_t is signed.
12075 (decode_timer): New function. Timers are now vectors of length 9,
12076 not 8, to accommodate the picosecond component.
12077 (timer_check_2): Use it.
12079 * nsterm.m (select_timeout, timeval_subtract): Remove.
12080 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
12081 as they're a bit more accurate and handle overflow better.
12082 (ns_select): Change prototype to be compatible with pselect.
12083 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
12084 * nsterm.h (ns_select): Adjust prototype.
12086 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
12087 us-resolution time stamps.
12088 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
12090 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
12092 * lisp.h (time_overflow): New decl.
12093 (wait_reading_process_output): First arg is now intmax_t, not int,
12094 to accommodate larger waits.
12096 * process.h (struct Lisp_Process.read_output_delay):
12097 Now counts nanoseconds, not microseconds.
12098 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
12100 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
12101 (wait_reading_process_output):
12102 Port to ns-resolution time stamps.
12103 (Faccept_process_output, wait_reading_process_output):
12104 Check for time stamp overflow. Do not assume time_t is signed.
12105 (select_wrapper): Remove; we now use pselect.
12106 (Fprocess_attributes): Now generates ns-resolution time stamps.
12108 * sysdep.c: Include utimens.h. Don't include utime.h
12109 or worry about struct utimbuf; gnulib does that for us now.
12110 (gettimeofday): Remove; gnulib provides a substitute.
12111 (make_timeval): New function.
12112 (set_file_times): Now sets ns-resolution time stamps.
12113 New arg FD; all uses changed.
12114 (time_from_jiffies, ltime_from_jiffies, get_up_time)
12115 (system_process_attributes):
12116 Now returns ns-resolution time stamp. All uses changed.
12117 Check for time stamp overflow.
12119 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
12120 provides a substitute now.
12122 * systime.h: Include timespec.h rather than sys/time.h and time.h,
12123 since it guarantees struct timespec.
12124 (EMACS_TIME): Now struct timespec, so that we can support
12125 ns-resolution time stamps.
12126 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
12127 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
12128 (EMACS_USECS): Remove.
12129 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
12130 so multiply the arg by 1000 before storing it.
12131 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
12133 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
12134 Port to ns-resolution time stamps.
12135 (EMACS_TIME_NEG_P): Remove; replaced by....
12136 (EMACS_TIME_SIGN): New macro.
12137 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
12138 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

12140 (make_timeval, make_lisp_time, decode_time_components): New decls.
12141 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
12142 that it mishandled time_t overflow. You can't compare by subtracting!
12143 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
12144 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
12146 * term.c: Include <sys/time.h>.
12147 (timeval_to_Time): New function, for proper overflow wraparound.
12148 (term_mouse_position, term_mouse_click): Use it.
12150 * undo.c (record_first_change): Support higher-resolution time stamps
12151 in the undo buffer.
12152 (Fprimitive_undo): Use them when restoring time stamps.
12154 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
12155 (w32_get_internal_run_time):
12156 Port to higher-resolution Emacs time stamps.
12157 (ltime): Now accepts single 64-bit integer, as that's more convenient
12160 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
12162 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
12163 for compatibility with pselect. Support ns-resolution time stamps.
12165 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
12167 * xselect.c (wait_for_property_change, x_get_foreign_selection):
12168 Check for time stamp overflow, and support ns-resolution time stamps.
12170 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
12171 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.

12183 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
12184 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
12185 staticidx goes up to 1597 out of 1600 = 0x640.)

12460 Use an inline function on all platforms when using the union type,

12606 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12607 would mishandle a string argument "Xc" if X was a multibyte

12623 2012-06-03 Ulrich Müller <ulm@gentoo.org>
12625 * Makefile.in (PAXCTL): Define.
12626 (temacs$(EXEEXT)): Disable memory randomization for the temacs
12627 binary via PaX flags if the paxctl utility is available.
12628 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
12629 Restore PaX flags to their default. (Bug#11398)
12631 2012-06-03 Chong Yidong <cyd@gnu.org>
12633 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
12634 buffer (Bug#11226).
12636 2012-06-03 Chong Yidong <cyd@gnu.org>
12638 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
12639 (note_mode_line_or_margin_highlight): If there is no help echo,
12640 use mode-line-default-help-echo. Handle the case where the mouse
12641 position is past the end of the mode line string.
12643 * buffer.c (buffer_local_value_1): New function, split from
12644 Fbuffer_local_value; can return Qunbound.
12645 (Fbuffer_local_value): Use it.
12646 (Vmode_line_format): Docstring tweaks.
12648 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

12660 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12662 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12663 Convert pctcpu and pctmem to Lisp float properly.
12664 Let the compiler fold better, as 100.0/0x8000 is exact.
12666 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
12668 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
12671 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

12675 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
12677 For a 'struct window', replace some Lisp_Object fields to
12678 bitfields where appropriate, remove unused fields.
12679 * window.h (struct window): Remove unused 'last_mark_x' and
12680 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12681 change its type from Lisp_Object to bitfield.
12682 Change type of 'force_start', 'optional_new_start',
12683 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
12684 fields from Lisp_Object to bitfield. Adjust users accordingly.
12686 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12688 Pacify gcc -Wdouble-precision when using Xaw.
12689 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
12690 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12691 Use 'float' consistently, rather than 'float' in most places
12692 and 'double' in a couple of places.
12694 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12696 * xdisp.c (handle_stop): Detect whether we have overlay strings
12697 loaded by testing it->current.overlay_string_index to be
12698 non-negative, instead of checking whether n_overlay_strings is
12699 positive. (Bug#11587)
12701 2012-05-31 Chong Yidong <cyd@gnu.org>
12703 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
12705 * doc.c (Fsubstitute_command_keys): Doc fix.
12707 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12709 * search.c (search_buffer): Remove calls to
12710 r_alloc_inhibit_buffer_relocation, as it is now called by
12711 maybe_unify_char, which was the cause of relocation of buffer text
12714 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12716 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12717 for the duration of call to load_charset, to avoid problems with
12718 callers of maybe_unify_char that access buffer text through C
12721 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12722 decrement the inhibition flag, instead of just setting or
12725 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12727 Remove obsolete '#define static' cruft.
12728 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12729 This #undef was "temporary" in 2000; it is no longer needed
12730 now that '#define static' has gone away.
12731 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12732 (gray_bitmap_bits): Remove; no longer needed.
12733 All uses replaced with definiens.
12734 * xterm.c: Include "bitmaps/gray.xbm".
12736 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
12738 Clean up __executable_start, monstartup when --enable-profiling.
12739 The following changes affect the code only when profiling.
12740 * dispnew.c (__executable_start): Rename from safe_bcopy.
12741 Define only on platforms that need it.
12742 * emacs.c: Include <sys/gmon.h> when profiling.
12743 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
12744 (__executable_start): Remove decl, since lisp.h does it now.
12745 (safe_bcopy): Remove decl; no longer has that name.
12746 (main): Coalesce #if into single bit of code, for simplicity.
12747 Cast pointers to uintptr_t, since standard libraries want integers
12749 * lisp.h (__executable_start): New decl.
12751 2012-05-31 Glenn Morris <rgm@gnu.org>
12753 * image.c (Fimagemagick_types): Doc fix.
12755 2012-05-30 Jim Meyering <meyering@redhat.com>
12757 * callproc.c (Fcall_process_region): Include directory component
12758 in mkstemp error message (Bug#11586).
12760 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
12762 * alloc.c, lisp.h (make_pure_vector): Now static.
12764 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

12770 (Qdefun): Move from eval.c.
12771 * lisp.h (Qdefun): Remove.
12772 * lread.c (read1): Tiny simplification.
12774 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
12776 Do not create empty overlays with the evaporate property (Bug#9642).
12777 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12778 Bug#9642, but explicitly check that the buffer the overlay would
12779 be moved to is live and rearrange lines to make sure that errors
12780 will not put the overlay in an inconsistent state.
12781 (Fdelete_overlay): Cosmetics.
12783 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12785 * w32term.c (my_bring_window_to_top): New function.
12786 (x_raise_frame): Use handle returned by DeferWindowPos, which
12787 could be different from the original one.
12788 Call my_bring_window_to_top instead of my_set_foreground_window.
12791 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
12792 by calling BringWindowToTop.

12797 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12799 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12800 This avoids undefined behavior that might cause the eassert
12801 to not catch an out-of-range value.
12803 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12805 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
12806 Update dependencies.
12808 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12810 * bidi.c (bidi_mirror_char): Fix last change.
12812 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
12814 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
12815 when referring to sectname field in printf format.
12817 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
12819 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12820 Only r_alloc_inhibit_buffer_relocation needed to be added;
12821 the others were already declared.
12823 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12824 before checking whether it's out of range. Put the check inside
12826 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12828 2012-05-27 Ken Brown <kbrown@cornell.edu>
12830 * callproc.c (Fcall_process): Restore a line that was accidentally
12831 commented out in the 2011-02-13 change (bug#11547).
12833 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12835 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12836 defined on ralloc.c.
12838 * buffer.c [REL_ALLOC]: Remove prototypes of
12839 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12840 they are now on lisp.h.
12842 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12844 * search.c (search_buffer): Use it to inhibit relocation of buffer
12845 text while re_search_2 is doing its job, because re_search_2 is
12846 passed C pointers to buffer text. (Bug#11519)
12848 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12849 Update value to 24.
12851 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12852 state after an additional call to move_it_in_display_line_to, keep
12853 the values of it->max_ascent and it->max_descent found for the
12855 (pos_visible_p): Revert the comparison against bottom_y to what it
12856 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12859 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12861 Fix coding-related core dumps with gcc -ftrapv.
12862 The code was computing A - B, where A and B are pointers, and B is
12863 random garbage. This can lead to core dumps on platforms that
12864 have special pointer registers, and it also leads to core dumps on
12865 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12866 A - B only when B is initialized properly.
12867 * coding.c (coding_set_source, coding_set_destination): Return void.
12868 (coding_change_source, coding_change_destinations): New functions,
12869 with the old behaviors of coding_set_source and coding_set_destination.
12870 All callers that need an offset changed to use these new functions.
12872 2012-05-26 Glenn Morris <rgm@gnu.org>
12874 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
12876 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12878 Extend mouse support on W32 text-mode console.
12879 * xdisp.c (draw_row_with_mouse_face):
12880 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12882 * w32console.c: Include window.h.
12883 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12885 (initialize_w32_display): Initialize mouse-highlight data.
12887 * w32inevt.c: Include termchar.h and window.h.
12888 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12889 moves, call note_mouse_highlight. If help_echo changed, call
12890 gen_help_event to produce help-echo message in the echo area.
12891 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12894 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12896 * lread.c (read1): Simplify slightly to avoid an overflow warning
12897 with GCC 4.7.0 on x86-64.
12899 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12901 * bidi.c (bidi_mirror_char): Revert last change: an int is
12902 definitely wide enough here.
12904 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12906 Fix integer width and related bugs (Bug#9874).
12907 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
12908 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
12909 (string_bytes, check_sblock, allocate_string_data):
12910 (compact_small_strings, Fmake_bool_vector, make_string)
12911 (make_unibyte_string, make_multibyte_string)
12912 (make_string_from_bytes, make_specified_string)
12913 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
12914 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
12916 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12917 (allocate_pseudovector):
12918 Use int, not EMACS_INT, where int is wide enough.
12919 (inhibit_garbage_collection, Fgarbage_collect):
12920 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12921 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12922 int might not be wide enough.
12923 (bidi_cache_search, bidi_cache_find, bidi_init_it)
12924 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
12925 (bidi_at_paragraph_end, bidi_find_paragraph_start)
12926 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
12927 (bidi_level_of_next_char, bidi_move_to_visually_next):
12928 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12929 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
12930 (Fkill_buffer, Fset_buffer_major_mode)
12931 (advance_to_char_boundary, Fbuffer_swap_text)
12932 (Fset_buffer_multibyte, overlays_at, overlays_in)
12933 (overlay_touches_p, struct sortvec, record_overlay_string)
12934 (overlay_strings, recenter_overlay_lists)
12935 (adjust_overlays_for_insert, adjust_overlays_for_delete)
12936 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
12937 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
12938 (Foverlay_recenter, last_overlay_modification_hooks_used)
12939 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
12940 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12941 (validate_region): Omit unnecessary test for b <= e,
12942 since that's guaranteed by the previous test.
12943 (adjust_overlays_for_delete): Avoid pos + length overflow.
12944 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12945 (report_overlay_modification):
12946 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12947 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12948 Omit pointer cast, which isn't needed anyway, and doesn't work
12949 after the EMACS_INT -> ptrdiff_t change.
12950 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12951 * buffer.h: Adjust decls to match defn changes elsewhere.
12952 (struct buffer_text, struct buffer):
12953 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12954 Use EMACS_INT, not int, where int might not be wide enough.
12955 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12956 not int, to avoid needless 32-bit limit on 64-bit hosts.
12957 (exec_byte_code): Use tighter memory-full test, one that checks
12958 for alloca overflow. Don't compute the address of the object just
12959 before an array, as that's not portable. Use EMACS_INT, not
12960 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12961 * callint.c (Fcall_interactively):
12962 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12963 * callproc.c (call_process_kill, Fcall_process):
12964 Don't assume pid_t fits into an Emacs fixnum.
12965 (call_process_cleanup, Fcall_process, child_setup):
12966 Don't assume pid_t fits into int.
12967 (call_process_cleanup, Fcall_process, delete_temp_file)
12968 (Fcall_process_region):
12969 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12970 (Fcall_process): Simplify handling of volatile integers.
12971 Use int, not EMACS_INT, where int will do.
12972 * casefiddle.c (casify_object, casify_region, operate_on_word)
12973 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
12974 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12975 (casify_object): Avoid integer overflow when overallocating buffer.
12976 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12977 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12978 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12979 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12980 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
12981 integers are now checked earlier. All uses replaced with XINT.
12983 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12984 For CCL_MapSingle, check that content and value are in int range.
12985 (ccl_driver, Fregister_code_conversion_map):
12986 Check that Vcode_version_map_vector is a vector.
12987 (resolve_symbol_ccl_program): Check that vector header is in range.
12988 Always copy the vector, so that we can check its contents reliably
12989 now rather than having to recheck each instruction as it's being
12990 executed. Check that vector words fit in 'int'.
12991 (ccl_get_compiled_code, Fregister_ccl_program)
12992 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12993 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12994 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12995 contents are in range.
12996 (Fccl_execute_on_string): Check that status is in range.
12997 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12998 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12999 Accept and return EMACS_INT, not int, because callers can pass values
13000 out of 'int' range.
13001 (c_string_width, strwidth, lisp_string_width, chars_in_text)
13002 (multibyte_chars_in_text, parse_str_as_multibyte)
13003 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
13004 (str_as_unibyte, str_to_unibyte, string_count_byte8)
13005 (string_escape_byte8, Fget_byte):
13006 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13007 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
13008 avoid mishandling large integers.
13009 * character.h: Adjust decls to match defn changes elsewhere.
13010 * charset.c (load_charset_map_from_file, find_charsets_in_text)
13011 (Ffind_charset_region):
13012 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13013 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
13014 (load_charset_map_from_vector, Fdefine_charset_internal):
13015 Don't assume fixnum fits in int.
13016 (load_charset_map_from_vector, Fmap_charset_chars):
13017 Remove now-unnecessary CHECK_NATNUMs.
13018 (Fdefine_charset_internal): Check ranges here, more carefully.
13019 Don't rely on undefined behavior with signed left shift overflow.
13020 Don't assume unsigned int fits into fixnum, or that fixnum fits
13021 into unsigned int. Don't require max_code to be a valid fixnum;
13022 that's not true for gb10830 4-byte on a 32-bit host. Allow
13023 invalid_code to be a cons, for the same reason. Require code_offset
13024 to be a character. Avoid int overflow if max_char is close
13026 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
13027 this is intended anyway and avoids some undefined behavior.
13028 (load_charset_map): Pass unsigned, not int, as 2nd arg of
13029 INDEX_TO_CODE_POINT, as that's what it expects.
13030 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
13031 * charset.h (DECODE_CHAR): Return int, not unsigned;
13032 this is what was intended anyway, and it avoids undefined behavior.
13033 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
13034 integer-overflow issues.
13035 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
13036 Formerly, it returned EMACS_INT on 64-bit hosts in the common case

13704 (SCROLL_BAR_VEC_SIZE): Remove; not used.
13706 2012-05-25 Glenn Morris <rgm@gnu.org>
13708 * lisp.mk (lisp): Update for more files being compiled now.
13710 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
13712 * lread.c: Remove `read_pure' which makes no difference.
13713 (read_pure): Remove var.
13714 (unreadpure): Remove function.
13715 (readevalloop): Don't call read_list with -1 flag.
13716 (read1, read_vector): Don't test read_pure any more.
13717 (read_list): Simplify.
13719 * fileio.c, character.h: Minor style tweaks.
13721 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
13723 * window.h (clip_changed): Remove useless declaration.
13725 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
13727 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
13728 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
13730 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
13733 This directory predates autoconf and is no longer needed nowadays.
13734 Move its few remaining bits of functionality to where they're needed.
13735 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
13736 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
13737 * m/template.h: Remove.
13738 * Makefile.in (M_FILE): Remove. All uses removed.
13739 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
13740 * lisp.h (USE_LSB_TAG):
13741 * mem-limits.h (EXCEEDS_LISP_PTR):
13742 Use VAL_MAX, not VALBITS, in #if.
13743 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
13744 (EMACS_UINT): Define unconditionally now.
13745 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
13746 (BITS_PER_EMACS_INT): New constants, replacing
13747 what used to be in config.h, but not useful in #if.
13748 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
13749 define them any more.
13750 (VAL_MAX): New macro.
13752 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
13753 BITS_PER_EMACS_INT, in #if.
13754 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
13755 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
13756 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
13757 * s/ms-w32.h (DATA_START):
13758 Move here from removed file m/intel386.h.
13759 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
13760 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
13762 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
13764 Assume C89 or later.
13765 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
13766 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
13768 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
13769 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
13770 * textprop.c, tparam.c (NULL): Remove.
13771 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
13772 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
13773 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
13774 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
13775 * xterm.c (input_signal_count): Assume volatile works.
13777 2012-05-21 Ken Brown <kbrown@cornell.edu>
13779 * xgselect.c (xg_select): Fix first argument in call to 'select'
13782 2012-05-20 Ken Brown <kbrown@cornell.edu>
13784 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
13785 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
13787 2012-05-19 Ken Brown <kbrown@cornell.edu>
13789 * xfns.c (x_in_use): Remove `static' qualifier.
13790 * xterm.h (x_in_use): Declare.
13791 * xgselect.c: Include xterm.h.
13792 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
13793 and `display_arg' (bug#9754).
13795 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
13797 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
13799 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
13800 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
13802 2012-05-18 Eli Zaretskii <eliz@gnu.org>
13804 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
13806 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
13807 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
13809 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
13810 reference to image_cache->refcount.
13811 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
13813 2012-05-17 Juri Linkov <juri@jurta.org>
13815 * search.c (Fword_search_regexp, Fword_search_backward)
13816 (Fword_search_forward, Fword_search_backward_lax)
13817 (Fword_search_forward_lax): Move functions to isearch.el
13818 (bug#10145, bug#11381).
13820 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13822 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13824 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13826 * lread.c (init_obarray): Declare Qt and Qnil as special.
13828 2012-05-14 Glenn Morris <rgm@gnu.org>
13830 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13831 Put "libexec" before "bin", for the sake of init_callproc_1.
13833 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13835 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13837 * unexaix.c: Port to more-recent AIX compilers.
13838 (report_error, report_error_1, make_hdr, copy_sym)
13839 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13840 Make arguments const char *, not char *, to avoid violations of C
13841 standard and to fix some AIX warnings reported by Gilles Pion.
13843 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13845 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13846 already have overlays loaded.
13847 (handle_single_display_spec): Before returning without displaying
13848 fringe bitmap, synchronize the bidi iterator with the main display
13849 iterator, by calling iterate_out_of_display_property.
13850 (iterate_out_of_display_property): Detect buffer iteration by
13851 testing that it->string is a Lisp string.
13852 (get_next_display_element): When the current object is exhausted,
13853 and there's something on it->stack, call set_iterator_to_next to
13854 proceed with what's on the stack, instead of returning zero.
13855 (set_iterator_to_next): If called at the end of a Lisp string,
13856 proceed to consider_string_end without incrementing string
13857 position. Don't increment display vector index past the end of
13858 the display vector. (Bug#11417)
13859 (pos_visible_p): Don't report a position visible when move_it_to
13860 stopped at the last line of window, which happens to be scanned
13861 backwards by the bidi iteration. (Bug#11464)
13863 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13865 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13866 and right-margin display specs even if the spec is invalid or we
13867 are on a TTY, and thus unable to display on the fringes.
13868 That's because the text with the property will not be displayed anyway,
13869 so we need to signal to the caller that this is a "replacing"
13870 display spec. This fixes display when the spec is invalid or we
13873 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13875 * unexaix.c (make_hdr): Fix typo in prototype.
13876 This bug broke the build on AIX. Problem reported by Gilles Pion.
13878 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13880 * keyboard.c (kbd_buffer_get_event): Read special events also in
13881 batch mode. (Bug#11415)
13883 2012-05-12 Glenn Morris <rgm@gnu.org>
13885 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13887 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13889 * lisp.mk (lisp): Add newcomment.elc.
13891 2012-05-12 Glenn Morris <rgm@gnu.org>
13893 * Makefile.in (MKDIR_P): New, set by configure.
13894 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13896 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13898 Remove unused function hourglass_started.
13899 * dispextern.h (hourglass_started):
13900 * w32fns.c (hourglass_started):
13901 * xdisp.c (hourglass_started): Remove.
13903 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13905 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13906 Update dependencies.
13908 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13910 * xgselect.c (xg_select): Put maxfds+1 into a var.
13911 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13913 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13915 2012-05-10 Dave Abrahams <dave@boostpro.com>
13917 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13918 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13920 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13922 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13923 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13924 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13925 Initialize xd_registered_buses.
13927 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13929 Untag more efficiently if USE_LSB_TAG.
13930 This is based on a proposal by YAMAMOTO Mitsuharu in
13931 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13932 For an admittedly artificial (nth 8000 longlist) benchmark on
13933 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13934 Emacs's overall text size by 1%.
13935 * lisp.h (XUNTAG): New macro.
13936 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13937 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13938 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13939 * eval.c (Fautoload):
13940 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13941 * frame.h (XFRAME): Use XUNTAG.
13943 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13944 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13945 Remove unportable assumptions about print widths of types like
13947 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13948 intptr_t when converting between pointer and integer, to avoid GCC
13949 warnings about wrong width.
13951 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13953 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13954 stack for each reader_thread, instead of defaulting to 8MB
13955 determined by the linker. This avoids failures in creating
13956 subprocesses on Windows 7, see the discussion in this thread:
13957 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13959 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13961 Fix up display of the *Minibuf-0* buffer in the mini window.
13962 * keyboard.c (read_char): Don't clear the echo area if there's no
13964 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13965 contents of *Minibuf-0*) if there's no message displayed in its stead.
13967 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13969 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13972 2012-05-06 Chong Yidong <cyd@gnu.org>
13974 * lisp.mk (lisp): Update.
13976 2012-05-05 Jim Meyering <meyering@redhat.com>
13978 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13980 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13982 * data.c (PUT_ERROR): New macro.
13983 (syms_of_data): Use it. Add new error type `user-error'.
13984 * undo.c (user_error): New function.
13985 (Fprimitive_undo): Use it.
13986 * print.c (print_error_message): Adjust print style for `user-error'.
13987 * keyboard.c (user_error): New function.
13988 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13990 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13992 Do not limit current-time-string to years 1000..9999.
13993 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13994 (Fcurrent_time_string): Support any year that is supported by the
13995 underlying localtime representation. Don't use asctime, as it
13996 has undefined behavior for years outside the range -999..9999.
13998 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
14000 Fix race conditions involving setenv, gmtime, localtime, asctime.
14001 Without this fix, interrupts could mess up code that uses these
14002 nonreentrant functions, since setting TZ invalidates existing
14003 tm_zone or tzname values, and since most of these functions return
14004 pointers to static storage.
14005 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
14006 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
14007 Grow the critical sections to include not just invoking
14008 localtime/gmtime, but also accessing these functions' results
14009 including their tm_zone values if any, and any related TZ setting.
14010 (format_time_string): Last arg is now struct tm *, not struct tm **,
14011 so that the struct tm is saved in the critical section.
14012 All callers changed. Simplify allocation of initial buffer, partly
14013 motivated by the fact that memory allocation needs to be outside
14014 the critical section.
14016 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
14018 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
14019 with RESET_INTERVAL.
14021 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
14022 Remove duplicated buffer name initialization.
14024 2012-05-02 Jim Meyering <jim@meyering.net>
14026 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
14028 * xfns.c (x_window): Use xstrdup (Bug#11375).
14030 2012-05-02 Eli Zaretskii <eliz@gnu.org>
14032 * xdisp.c (pos_visible_p): If already at a newline from the
14033 display string before the 'while' loop, don't walk back the glyphs
14034 from it3.glyph_row. Solves assertion violation when the display
14035 string begins with a newline (egg.el). (Bug#11367)
14037 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
14039 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
14042 2012-05-01 Glenn Morris <rgm@gnu.org>
14044 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
14045 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
14046 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
14047 All were removed before 23.1.
14049 * dispnew.c: Remove HAVE_LIBNCURSES test;
14050 it is always true on relevant platforms.
14052 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
14053 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
14055 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
14057 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
14059 * .gdbinit (xpr): Remove checks for no longer existing misc types.
14060 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
14063 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
14065 Do not avoid creating empty evaporating overlays (Bug#9642).
14066 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
14067 That is, do not delete an evaporating overlay if it becomes
14068 empty after its bounds are adjusted to fit within its buffer.
14069 This fix caused other problems, and I'm reverting it until we get
14070 to the bottom of them.
14072 2012-04-27 Chong Yidong <cyd@gnu.org>
14074 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
14076 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14078 * xdisp.c (pos_visible_p): If the window start position is beyond
14079 ZV, start the display from buffer beginning. Prevents assertion
14080 violation in init_iterator when the minibuffer window is scrolled
14081 via the scroll bar.
14083 * window.c (window_scroll_pixel_based): Likewise.
14085 2012-04-27 Chong Yidong <cyd@gnu.org>
14087 * keymap.c (where_is_internal): Doc fix (Bug#10872).
14089 2012-04-27 Glenn Morris <rgm@gnu.org>
14091 * fileio.c (Fcopy_file, Fset_file_selinux_context):
14092 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
14094 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14096 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
14097 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
14099 2012-04-26 Eli Zaretskii <eliz@gnu.org>
14101 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
14102 display element, check also the underlying string or buffer
14103 character. (Bug#11341)
14105 * w32menu.c: Include w32heap.h.
14106 (add_menu_item): If the call to AppendMenuW (via
14107 unicode_append_menu) fails, disable Unicode menus only if we are
14108 running on Windows 9X/Me.
14110 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
14112 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
14113 (xgetint): Add missing shift for LSB tags.
14115 2012-04-24 Martin Rudalics <rudalics@gmx.at>
14117 * keyboard.c (read_char): Don't wipe echo area for select window
14118 events: These might get delayed via `mouse-autoselect-window'
14121 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
14123 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
14124 manipulation of :loaded-from data.
14126 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
14128 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
14129 now a cons (bug#11311).
14131 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
14133 Do not create empty overlays with the evaporate property (Bug#9642).
14134 * buffer.c (Fmove_overlay): Delete an evaporating overlay
14135 if it becomes empty after its bounds are adjusted to fit within
14136 its buffer. Without this fix, in a nonempty buffer (let ((o
14137 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
14138 yields an empty overlay that has the evaporate property, which is
14139 not supposed to happen.
14141 Fix minor GTK3 problems found by static checking.
14142 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14143 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14144 (struct _EmacsFixedClass, emacs_fixed_get_type):
14145 Move decls here from emacsgtkfixed.h, since they needn't be public.
14146 (emacs_fixed_get_type): Now static.

14343 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14344 (NEED_MEM_INSERT): New macro.
14345 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14346 Remove one incorrect comment and fix another.

14382 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14383 * s/netbsd.h, s/sol2-6.h:
14384 Remove definition of GC_MARK_STACK, since the default now works.
14385 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

14413 2012-04-11 Daniel Colascione <dancol@dancol.org>
14415 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14416 against is gone. It's better to use vfork now so that when Cygwin
14417 gains a new, working vfork, we use it automatically (bug#10398).
14419 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

14472 * minibuf.c (Fread_variable): Callers changed.
14474 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14476 * xdisp.c (set_cursor_from_row): If the display string appears in
14477 the buffer at position that is closer to point than the position
14478 after the display string, display the cursor on the first glyph of
14479 the display string. Fixes cursor display when a 'display' text
14480 property immediately follows invisible text. (Bug#11094)
14482 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14484 composite.c: use 'double' consistently
14485 * composite.c (get_composition_id): Use 'double' consistently
14486 instead of converting 'float' to 'double' and vice versa; this is
14487 easier to understand and avoids a GCC warning.
14489 2012-04-09 Glenn Morris <rgm@gnu.org>
14491 * Makefile.in: Generate leim-list with bootstrap-emacs, in

14541 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14543 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14544 Call init_libxml2_functions before calling libxml2 functions.

14556 point, use it.vpos to compute how many lines to backtrack after
14557 move_it_to point. (Bug#11133)
14559 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14561 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14562 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14563 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14564 macros related to unification of CJK characters. For the details,
14565 see the discussion following the message here:

14579 * w32menu.c (is_simple_dialog): Properly check lisp types.
14582 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14584 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14585 position we get to after a call to move_it_to fails the
14586 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14587 only if we wind up in a string from display property. (Bug#11063)
14589 * window.c (Fdelete_other_windows_internal): Invalidate the row
14590 and column information about mouse highlight, so that redisplay
14591 restores it after reallocating the glyph matrices. (Bug#7464)
14593 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14594 string comes from a `display' text property, use the buffer
14595 position of that property as if we actually saw that position in
14597 (move_it_by_lines): Remove the assertion that
14598 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14599 violated when there's a before-string at the beginning of a line.
14602 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14604 * xdisp.c (append_space_for_newline): If the default face was
14605 remapped, use the remapped face for the appended newline.
14606 (extend_face_to_end_of_line): Use the remapped default face for
14607 extending the face to the end of the line.
14608 (display_line): Call extend_face_to_end_of_line when the default
14609 face was remapped. (Bug#11068)
14611 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14613 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
14615 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14617 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
14619 2012-03-27 Glenn Morris <rgm@gnu.org>
14621 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
14624 2012-03-26 Kenichi Handa <handa@m17n.org>
14626 * dispextern.h (struct glyph): Fix previous change. Change the
14627 bit length of glyphless.ch to 25 (Bug#11082).
14629 2012-03-26 Chong Yidong <cyd@gnu.org>
14631 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14632 (command_loop_1): Use it; inhibit selection update for
14633 handle-select-window too (Bug#8996).
14635 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
14637 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14639 2012-03-25 Kenichi Handa <handa@m17n.org>
14641 * dispextern.h (struct glyph): Change the bit length of
14642 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14644 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14646 * s/ms-w32.h (tzname): Include time.h before redirecting to
14647 _tzname. Fixes the MSVC build. (Bug#9960)
14649 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
14651 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
14654 * xterm.c (XTread_socket): Only modify handling_signal if
14655 !SYNC_INPUT. (Bug#11080)
14657 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14659 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14660 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14661 when fetching a multibyte character consumes more bytes than
14662 CHAR_BYTES returns, due to unification of CJK characters in
14663 string_char. (Bug#11073)
14665 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14667 * process.c (wait_reading_process_output): Handle pty disconnect
14668 by refraining from sending oneself a SIGCHLD (bug#10933).
14670 2012-03-22 Chong Yidong <cyd@gnu.org>
14672 * dispextern.h (struct it): New member string_from_prefix_prop_p.
14674 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
14675 Mark string as coming from a prefix property.
14676 (handle_face_prop): Use default face for prefix strings (Bug#4281).
14677 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
14679 2012-03-21 Chong Yidong <cyd@gnu.org>
14681 * xfaces.c (Vface_remapping_alist): Doc fix.
14683 2012-03-20 Eli Zaretskii <eliz@gnu.org>
14685 * w32proc.c (Fw32_set_console_codepage)
14686 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
14689 2012-03-20 Chong Yidong <cyd@gnu.org>
14691 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
14692 to reflect default non-nil value of redisplay-dont-pause.
14694 2012-03-19 Kenichi Handa <handa@m17n.org>
14696 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
14697 it fit in a valid range (Bug#11003).
14699 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14701 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14702 that is not from display property, accept the row as a "cursor
14703 row" if one of the string's character has a non-nil `cursor'
14704 property. Fixes cursor positioning when there are newlines in
14705 overlay strings, e.g. in icomplete.el. (Bug#11035)
14707 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14709 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14711 2012-03-12 Chong Yidong <cyd@gnu.org>
14713 * eval.c (inhibit_lisp_code): Rename from
14714 inhibit_window_configuration_change_hook; move from window.c.
14716 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14717 * window.c (run_window_configuration_change_hook)
14718 (syms_of_window): Callers changed.
14720 2012-03-11 Chong Yidong <cyd@gnu.org>
14722 * keymap.c (Fkey_description): Doc fix (Bug#9700).
14724 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
14726 2012-03-10 Chong Yidong <cyd@gnu.org>
14728 * frame.c (other_visible_frames): Don't assume the selected frame
14729 is visible (Bug#10955).
14731 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
14733 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
14735 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
14737 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
14738 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14741 2012-03-03 Glenn Morris <rgm@gnu.org>
14743 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14745 2012-03-02 Eli Zaretskii <eliz@gnu.org>
14747 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
14748 position past the first glyph_row that ends at ZV. (Bug#10902)
14749 (redisplay_window, next_element_from_string): Fix typos in
14751 (redisplay_window): Pass to move_it_vertically the margin in
14752 pixels, not in screen lines.
14754 2012-03-02 Glenn Morris <rgm@gnu.org>
14756 * buffer.c (buffer-list-update-hook): Doc fix.
14758 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14760 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14761 push_it before setting up the iterator for the first overlay
14762 string, even if we have an empty string loaded.
14763 (next_overlay_string): If there's an empty string on the iterator
14764 stack, pop the stack. (Bug#10903)
14766 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14768 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14769 Suggested by Stefan Monnier in
14770 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14771 * alloc.c (widen_to_Lisp_Object): New static function.
14772 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14773 and widening them to Lisp_Objects. This would work even if
14774 USE_LSB_TAG is defined and wide integers are used, which might
14775 happen in a future version of Emacs.
14777 2012-02-25 Chong Yidong <cyd@gnu.org>
14779 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
14782 * xselect.c (Fx_selection_exists_p): Doc fix.
14783 (x_clipboard_manager_save_all): Print an informative message
14784 before saving to clipboard manager.
14786 2012-02-24 Chong Yidong <cyd@gnu.org>
14788 * keyboard.c (process_special_events): Handle all X selection
14789 requests in kbd_buffer, not just the next one (Bug#8869).
14791 2012-02-23 Chong Yidong <cyd@gnu.org>
14793 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14794 call when setting menu-bar-lines and tool-bar-lines parameters.
14795 (unwind_create_frame_1): New helper function.
14797 * window.c (inhibit_window_configuration_change_hook): New var.
14798 (run_window_configuration_change_hook): Obey it.
14799 (syms_of_window): Initialize it.
14801 2012-02-22 Chong Yidong <cyd@gnu.org>
14803 * xterm.c (x_draw_image_relief): Add missing type check for
14804 Vtool_bar_button_margin (Bug#10743).
14806 2012-02-21 Chong Yidong <cyd@gnu.org>
14808 * fileio.c (Vfile_name_handler_alist): Doc fix.
14810 * buffer.c (Fget_file_buffer): Protect against invalid file
14811 handler return value.
14813 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
14815 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
14816 when computing $valmask.
14818 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14819 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14820 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14821 It's useless in that case, and it can cause problems on hosts
14822 that allocate halves of EMACS_INT values separately.
14823 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14824 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14825 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14826 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14827 it avoids undefined behavior on hosts where shifting right by more
14828 than the word width has undefined behavior.
14830 2012-02-19 Chong Yidong <cyd@gnu.org>
14832 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14833 (Funhandled_file_name_directory, Ffile_name_as_directory)
14834 (Fdirectory_file_name, Fexpand_file_name)
14835 (Fsubstitute_in_file_name): Protect against invalid file handler
14836 return values (Bug#10845).
14838 2012-02-18 Eli Zaretskii <eliz@gnu.org>
14840 * .gdbinit (pitx): Fix incorrect references to fields of the
14843 2012-02-17 Chong Yidong <cyd@gnu.org>

14850 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14852 2012-02-15 Chong Yidong <cyd@gnu.org>
14854 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14855 marked as special. Also, starting docstrings with * is obsolete.
14857 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
14859 * gnutls.c (emacs_gnutls_write): Fix last change.

14868 * keymap.c (Fsingle_key_description): Handle char ranges.
14870 2012-02-12 Chong Yidong <cyd@gnu.org>
14872 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14873 as that creates a dangerous corner case.
14875 * window.c (Fdelete_window_internal): Invalidate the mouse
14876 highlight (Bug#9904).
14878 2012-02-12 Glenn Morris <rgm@gnu.org>
14880 * xselect.c (Fx_own_selection_internal)
14881 (Fx_get_selection_internal, Fx_disown_selection_internal)
14882 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
14883 * nsselect.m (Fx_own_selection_internal)
14884 (Fx_disown_selection_internal, Fx_selection_exists_p)
14885 (Fx_selection_owner_p, Fx_get_selection_internal):
14886 Sync docs and argument specs with the xselect.c versions.
14888 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
14890 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
14892 2012-02-11 Eli Zaretskii <eliz@gnu.org>
14894 * w32select.c (Fx_selection_exists_p): Sync doc string and
14895 argument list with xselect.c. (Bug#10783)
14897 * w16select.c (Fx_selection_exists_p): Sync doc string and
14898 argument list with xselect.c. (Bug#10783)

14904 2012-02-09 Kenichi Handa <handa@m17n.org>
14906 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
14908 2012-02-07 Chong Yidong <cyd@gnu.org>
14910 * buffer.c (Fbuffer_local_variables)
14911 (buffer_lisp_local_variables): Handle unbound vars correctly;
14912 don't let Qunbound leak into Lisp.
14914 2012-02-07 Glenn Morris <rgm@gnu.org>
14916 * image.c (Fimagemagick_types): Doc fix.
14918 * image.c (imagemagick-render-type): Change it from a lisp object
14919 to an integer. Move the doc here from the lisp manual.
14920 Treat all values not equal to 0 the same.
14922 2012-02-06 Chong Yidong <cyd@gnu.org>
14924 * doc.c (store_function_docstring): Avoid applying docstring of
14925 alias to base function (Bug#2603).

14939 Include --enable-checking, if specified, in the return value.
14941 2012-02-04 Martin Rudalics <rudalics@gmx.at>
14943 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
14944 after rounding frame sizes. (Bug#9723)
14946 2012-02-04 Eli Zaretskii <eliz@gnu.org>
14948 * keyboard.c (adjust_point_for_property): Don't position point
14949 before BEGV. (Bug#10696)
14951 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
14953 Handle overflow when computing char display width (Bug#9496).
14954 * character.c (char_width): Return EMACS_INT, not int.
14955 (char_width, c_string_width): Check for overflow when
14956 computing the width; this is possible now that individual
14957 characters can have unbounded width. Problem introduced
14958 by merge from Emacs 23 on 2012-01-19.
14960 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
14962 * dbusbind.c (Fdbus_register_method): Mention the return value
14963 :ignore in the docstring.
14965 2012-02-02 Glenn Morris <rgm@gnu.org>
14967 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
14969 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

14975 2012-02-02 Kenichi Handa <handa@m17n.org>
14977 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
14978 0, do not call append_composite_glyph.
14980 2012-02-02 Kenichi Handa <handa@m17n.org>
14982 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
14984 (x_produce_glyphs): If the component of a composition is a null
14985 string, set it->pixel_width to 1 to avoid zero-width glyph.
14987 2012-02-01 Eli Zaretskii <eliz@gnu.org>
14989 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
14990 first 2 arguments are identical. This makes inserting large
14991 output from a subprocess an order of magnitude faster on
14992 MS-Windows, where all sbrk'ed memory is always contiguous.
14994 2012-01-31 Glenn Morris <rgm@gnu.org>
14996 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

15032 2012-01-21 Chong Yidong <cyd@gnu.org>
15034 * floatfns.c (Fcopysign): Make the second argument non-optional,
15035 since nil is not allowed anyway.
15037 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
15039 * process.c (read_process_output): Use p instead of XPROCESS (proc).
15040 (send_process): Likewise.
15042 2012-01-19 Martin Rudalics <rudalics@gmx.at>
15044 * window.c (save_window_save, Fcurrent_window_configuration)
15045 (Vwindow_persistent_parameters): Do not use Qstate.
15046 Rewrite doc-strings.
15048 2012-01-19 Kenichi Handa <handa@m17n.org>
15050 * character.c (char_width): New function.
15051 (Fchar_width, c_string_width, lisp_string_width):
15052 Use char_width (Bug#9496).
15054 2012-01-16 Martin Rudalics <rudalics@gmx.at>
15056 * window.c (Vwindow_persistent_parameters): New variable.
15057 (Fset_window_configuration, save_window_save): Handle persistent

15607 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
15608 Otherwise, valgrind does not work on some platforms.
15609 Problem reported by Andreas Schwab in
15610 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
15611 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15612 is set, removing the need for VIRT_ADDRESS_VARIES.
15613 (PURE_P): Use a more-efficient implementation that needs just one
15614 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
15615 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
15616 to 4 (xorl, subq, cmpq, setbe).
15617 * alloc.c (pure): Always extern now, since that's the
15618 VIRT_ADDR_VARIES behavior.

15620 consistency with the new puresize.h.
15621 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
15622 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

15630 behave as if the cursor position were at the window margin.
15632 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15633 and the cursor position is out of bounds, behave as if the cursor
15634 position were at the window margin. (Bug#10075)
15636 2011-11-18 Chong Yidong <cyd@gnu.org>
15638 * window.c (Fwindow_combination_limit): Make first argument

15659 * xdisp.c (row_hash): New function, body extracted from
15660 compute_line_metrics.
15661 (compute_line_metrics): Call row_hash, instead of computing the
15664 * dispnew.c (verify_row_hash): Call row_hash for computing the
15665 hash code of a row, instead of duplicating code from xdisp.c.
15667 * dispextern.h (row_hash): Add prototype.
15669 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

15705 2011-11-14 Eli Zaretskii <eliz@gnu.org>
15707 * xdisp.c (display_line): Move the call to
15708 highlight_trailing_whitespace before the call to
15709 compute_line_metrics, since the latter needs to see the final
15710 faces of all the glyphs to compute ROW's hash value.
15711 Fixes assertion violations in row_equal_p. (Bug#10035)
15713 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
15715 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

15720 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
15721 with user-defined heap size. Bump the default size of the temacs

15725 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
15726 current_matrix and desired_matrix. (Bug#9990)
15727 (verify_row_hash) [XASSERTS]: New function.

15772 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
15774 Avoid some portability problems by eschewing 'extern inline' functions.
15775 The trivial performance wins aren't worth the portability hassles; see
15776 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
15778 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

15844 * xmenu.c (cleanup_widget_value_tree): New function.
15845 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

15852 (window_box_width, window_box_left, window_box_left_offset)
15853 (window_box_right, window_box_right_offset): Declare extern.
15854 Otherwise, these inline functions do not conform to C99 and
15855 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15856 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15857 * intervals.c (adjust_intervals_for_insertion)

15860 (static_offset_intervals): Remove.
15861 (offset_intervals): Rewrite using the old contents of
15862 static_offset_intervals. The old version didn't conform to C99

15991 matrices of the partially constructed frame. (Bug#9943)
15992 * xfns.c (unwind_create_frame): Likewise.
15994 2011-11-01 Eli Zaretskii <eliz@gnu.org>
15996 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
15997 Don't stop backward scan on the continuation glyph, even though
15998 its CHARPOS is positive.
15999 (mouse_face_from_buffer_pos, note_mouse_highlight):
16000 Rename cover_string to disp_string.
16002 2011-11-01 Martin Rudalics <rudalics@gmx.at>
16004 * window.c (temp_output_buffer_show): Don't use
16005 Vtemp_buffer_show_specifiers.
16006 (Vtemp_buffer_show_specifiers): Remove unused variable.
16008 2011-10-30 Eli Zaretskii <eliz@gnu.org>
16010 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
16011 past the beginning of the current glyph matrix.
16013 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
16015 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
16016 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
16017 HAVE_GTK3 (Bug#9869).
16019 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
16020 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
16022 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
16024 * xterm.c: Declare x_handle_net_wm_state to return int.
16025 (handle_one_xevent): Check if we are iconified but don't have
16026 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
16027 (get_current_wm_state): Return non-zero if not hidden,
16028 check for _NET_WM_STATE_HIDDEN (Bug#9893).
16029 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
16030 (x_handle_net_wm_state): Return what get_current_wm_state returns.
16031 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
16033 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
16035 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
16036 so that this new function doesn't get optimized away by a
16037 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
16039 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
16041 * frame.h (MOUSE_HL_INFO): Remove excess parens.
16043 2011-10-29 Eli Zaretskii <eliz@gnu.org>
16045 Fix the `xbytecode' command.
16046 * .gdbinit (xprintbytestr): New command.
16047 (xwhichsymbols): Rename from `which'; all callers changed.
16048 (xbytecode): Print the byte-code string as well.
16050 2011-10-29 Kim Storm <storm@cua.dk>
16052 * alloc.c (which_symbols): New function.
16054 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
16056 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
16059 2011-10-29 Glenn Morris <rgm@gnu.org>
16061 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
16062 Not clear what it was for, and it causes various bugs. (Bug#9839)
16064 2011-10-28 Eli Zaretskii <eliz@gnu.org>
16066 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
16067 possible random value that matches one of those tested as
16068 condition to clear the mouse face.
16070 2011-10-28 Chong Yidong <cyd@gnu.org>
16072 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
16074 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
16076 * window.c (make_window): Initialize phys_cursor_on_p.
16078 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
16080 * lisp.h (struct Lisp_Symbol): Update comments.
16082 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
16084 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
16086 2011-10-28 Eli Zaretskii <eliz@gnu.org>
16088 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
16089 <oslsachem@gmail.com> for helping to debug this.
16091 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
16092 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
16093 (g_b_init_get_glyph_outline_w): New static variables.
16094 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
16095 (GetGlyphOutlineW_Proc): New typedefs.
16096 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
16097 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
16099 (w32font_open_internal, compute_metrics):
16100 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
16101 instead of calling the "wide" APIs directly.
16103 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
16105 * w32.h (syms_of_w32font): Add prototype.
16107 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
16109 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
16110 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
16111 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
16112 (Fmove_to_window_line): Doc fix.
16114 2011-10-27 Chong Yidong <cyd@gnu.org>
16116 * process.c (make_process): Set gnutls_state to NULL.
16118 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
16119 non-NULL, regardless of GNUTLS_INITSTAGE.
16120 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
16121 an error. Set process slots as soon as we allocate them.
16123 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
16125 2011-10-27 Chong Yidong <cyd@gnu.org>
16127 * gnutls.c (emacs_gnutls_deinit): New function.
16128 Deallocate credentials structures as well as calling gnutls_deinit.
16129 (Fgnutls_deinit, Fgnutls_boot): Use it.
16131 * process.c (make_process): Initialize GnuTLS credentials to NULL.
16132 (deactivate_process): Call emacs_gnutls_deinit.
16134 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
16136 * image.c (x_create_x_image_and_pixmap):
16137 * w32.c (sys_rename, w32_delayed_load):
16138 * w32font.c (fill_in_logfont):
16139 * w32reg.c (x_get_string_resource): Silence compiler warnings.
16141 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
16143 * w32fns.c (w32_default_color_map): New function,
16144 extracted from Fw32_default_color_map.
16145 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
16147 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
16149 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
16151 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
16153 * keyboard.c (test_undefined): New function (bug#9751).
16154 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
16156 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
16158 * sysdep.c (init_sys_modes): Fix the check for the controlling
16159 terminal (Bug#6649).
16161 2011-10-20 Eli Zaretskii <eliz@gnu.org>
16163 * dispextern.h (struct bidi_it): New member next_en_type.
16165 * bidi.c (bidi_line_init): Initialize the next_en_type member.
16166 (bidi_resolve_explicit_1): When next_en_pos is valid for the
16167 current character, check also for next_en_type being WEAK_EN.
16168 (bidi_resolve_weak): Don't enter the expensive loop if the current
16169 position is before next_en_pos. Record the bidi type of the first
16170 non-ET, non-BN character we find, in addition to its position.
16171 (bidi_level_of_next_char): Invalidate next_en_type when
16172 next_en_pos is over-stepped.
16174 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
16176 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
16177 * editfns.c: Rewrite current-time-zone so that it invokes
16178 the equivalent of (format-time-string "%Z") to get the time zone name.
16179 This fixes a bug when the time zone name contains characters that
16180 need converting from the system time locale to Emacs internal format.
16181 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
16182 that patch fixed format-time-string to do the conversion, but
16183 I forgot to fix current-time-zone.
16184 (format_time_string): New function, containing most of
16185 what Fformat_time_string used to contain.
16186 (Fformat_time_string): Rewrite in terms of format_time_string.
16187 This doesn't change this function's behavior.
16188 (current-time-zone): Rewrite to use format_time_string.
16189 This fixes the bug reported by Michael Schierl in
16190 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
16191 Jason Rumney's 2007-06-07 change worked around this bug, but
16193 * systime.h (tzname, timezone): Remove no-longer-used declarations.
16195 2011-10-19 Eli Zaretskii <eliz@gnu.org>
16197 * xdisp.c (start_display): If the character at POS is displayed
16198 via a display vector, reset IT->current.dpvec_index to zero.
16199 (try_window_reusing_current_matrix): If a line ends in a display
16200 vector or the next line starts in a display vector, continue
16201 redrawing the window even though the character position of
16202 start_row was reached.
16205 2011-10-18 Chong Yidong <cyd@gnu.org>
16207 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
16208 with nobreak-char-display too.
16210 2011-10-18 Eli Zaretskii <eliz@gnu.org>
16212 Fix part 3 of bug#9771.
16213 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
16214 (bidi_resolve_neutral): Don't enter the expensive loop looking for
16215 non-neutral characters if the current character is a paragraph
16216 separator (a.k.a. Newline). This avoids running the same
16217 expensive loop twice, once when we consume the preceding newline
16218 and the other time when the line actually needs to be displayed.
16219 Avoid the loop when we see neutrals on the base embedding level
16220 following a character whose directionality is the same as the
16221 paragraph's. This avoids running the expensive loop when a line
16222 ends in a long sequence of neutrals, like control characters.
16223 Add assertion against STRONG_AL type. Slightly rearrange code
16224 that determines the type of a neutral given the first non-neutral
16226 (bidi_level_of_next_char): Set next_en_pos to zero when
16227 invalidating its info.
16229 2011-10-17 Eli Zaretskii <eliz@gnu.org>
16231 * xdisp.c (push_display_prop): Determine whether to record string
16232 or buffer position by IT->string, not by IT->method. Allow
16233 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
16234 (move_it_vertically_backward): Don't look for character position
16235 immediately after the newline when in a continuation line.
16238 2011-10-15 Martin Rudalics <rudalics@gmx.at>
16240 * window.c (coordinates_in_window): Rewrite and delabelize
16241 vertical border check. (Bug#5357) (Bug#9618)
16243 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
16245 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
16246 errors in XSetWindowBorder (bug#9310).
16248 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
16250 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
16251 avoid crash when xmalloc overrun checking is enabled.
16253 2011-10-13 Eli Zaretskii <eliz@gnu.org>
16255 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
16256 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
16257 cursor motion with <left> and <right> arrow keys.
16259 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
16260 some callers set that themselves.
16262 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16264 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
16265 display string and the previous row comes from the same string and
16266 is empty. (Bug#9739) (Bug#9738)
16268 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
16270 * doc.c (get_doc_string): Encode file name (bug#9735).
16272 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16274 * bidi.c (bidi_level_of_next_char):
16275 * xdisp.c (get_visually_first_element): Remove old incorrect
16276 comments regarding the Unicode Line Separator character.
16278 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
16280 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
16282 * alloc.c (Fgc_status): Do not access beyond zombies array
16283 boundary if nzombies > MAX_ZOMBIES.
16284 * alloc.c (dump_zombies): Add missing format specifier.
16286 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16288 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16289 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16291 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16292 Some packages use them to denote characters with modifiers.
16294 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16296 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16297 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16298 matching a pp-number. Rename parameter var to var1.
16300 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16302 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16304 2011-10-08 Glenn Morris <rgm@gnu.org>
16306 * callint.c (Fcall_interactively): Give a more explicit error for the
16307 'c' case with a non-character input. (Bug#8479)
16309 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16311 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16313 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16314 lines that are hscrolled on the left.
16316 * dispnew.c (buffer_posn_from_coords): Account for a possible
16317 presence of header-line. (Bug#4426)
16319 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16321 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16322 Don't advertise functionality which we discourage or doesn't work.
16324 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16326 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16327 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16328 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16329 this makes Emacs dump core during garbage collection on rare
16330 occasions. sizeof is obviously inferior to offsetof here, so
16331 stick with offsetof.
16332 (GC_POINTER_ALIGNMENT): New macro.
16333 (mark_memory): Omit 3rd (offset) arg; caller changed.
16334 Don't assume EMACS_INT alignment is the same as pointer alignment.
16336 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16338 * keyboard.c (read_key_sequence_remapped): New var.
16339 (read_key_sequence): Compute remapping in the right buffer.
16340 (command_loop_1): Use read_key_sequence's remapping directly.
16342 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16344 * dired.c (file_name_completion): Don't expand file name.
16345 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16346 before checking file name handler.
16348 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16349 they've been requested explicitly (bug#9591).
16351 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16353 * keymap.c (Fsingle_key_description): Use make_specified_string
16354 instead of build_string to build string from push_key_description.
16357 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16359 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16360 This fixes a Y2038 bug on 64-bit hosts.
16361 * buffer.c (reset_buffer):
16362 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16363 (Fclear_buffer_auto_save_failure):
16364 Use 0, not -1, to represent an unset failure time, since time_t
16365 might not be signed.
16367 Remove dependency on glibc malloc internals.
16368 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16369 Move back here from lisp.h, but with their new implementations.
16370 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16371 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16372 * charset.c (charset_table_init): New static var.
16373 (syms_of_charset): Use it instead of xmalloc. This removes a
16374 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16375 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16376 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16377 Move back to alloc.c.
16378 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16379 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16381 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16383 * nsterm.m (windowDidResize): Call x_set_window_size only when
16384 ns_in_resize is true. Otherwise set pixelwidth/height and
16385 call change_frame_size (Bug#9628).
16387 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16389 Port --enable-checking=all to Fedora 14 x86-64.
16390 * charset.c (syms_of_charset): Also account for glibc malloc's
16391 internal overhead when calculating the initial malloc maximum.
16393 Port --enable-checking=all to Fedora 14 x86.
16394 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16396 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16397 (overrun_check_realloc, overrun_check_free):
16398 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16399 That way, xmalloc returns a properly-aligned pointer even if
16400 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16401 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16402 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16403 into account when calculating the initial malloc maximum.
16404 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16405 Move here from alloc.c, so that charset.c can use it too.
16406 Properly align; the old code wasn't right for common 32-bit hosts
16407 when configured with --enable-checking=all.
16408 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16409 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16411 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16413 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16416 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16418 * xdisp.c (compute_display_string_end): If there's no display
16419 string at CHARPOS, return -1.
16421 * bidi.c (bidi_fetch_char): When compute_display_string_end
16422 returns a negative value, treat the character as a normal
16423 character not covered by a display string. (Bug#9624)
16425 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16427 * lread.c (Fread_from_string): Fix typo in docstring.
16429 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16431 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16432 newline, reseat the iterator instead of bidi-iterating there one
16433 character at a time. (Bug#9610)
16434 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16435 TO_CHARPOS if the bidi iterator is at base embedding level.

16445 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16447 2011-09-25 Glenn Morris <rgm@gnu.org>
16449 * buffer.c (truncate-lines): Doc fix.
16451 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16453 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16454 (Fset_window_next_buffers): Doc fix.

16466 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16468 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16469 Default value is now t. Doc fix.
16471 * indent.c (Fvertical_motion): Compute and apply the overshoot
16472 logic when moving up, not only when moving down. Fix the
16473 confusing name and values of the it_overshoot_expected variable;
16474 logic changes accordingly. (Bug#9254) (Bug#9549)
16476 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16477 CHARPOS is covered by a display string which includes newlines.
16478 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16479 is covered by a display string with embedded newlines.
16481 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16483 * dbusbind.c (Fdbus_register_signal): Add match rule to
16484 Vdbus_registered_objects_table. (Bug#9581)

16488 2011-09-24 Jim Meyering <meyering@redhat.com>
16490 do not ignore write error for any output size
16491 The previous change was incomplete.
16492 While it makes emacs --batch detect the vast majority of stdout
16493 write failures, errors were still ignored whenever the output size is
16494 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16495 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16496 && echo FAIL: ignored write error
16497 FAIL: ignored write error
16498 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16499 && echo FAIL: ignored write error
16500 FAIL: ignored write error
16501 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16503 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16505 * emacs.c (Fkill_emacs): In noninteractive mode exit
16506 non-successfully if a write error occurred on stdout. (Bug#9574)
16508 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16510 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16513 * dispextern.h (struct it): Update the comment documenting what
16516 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16518 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16519 a display string, extend search for cursor position to end of row.
16520 (find_row_edges): If the row ends in a newline from a display
16521 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16522 Handle the case of a display string with multiple newlines.
16523 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16524 non-empty line. Fixes confusing cursor motion with arrow keys at
16525 the beginning of a line that starts with whitespace.

16529 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16532 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16534 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16535 boolean (Bug#9154).
16537 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16539 * xdisp.c (display_line): Record maximum and minimum buffer
16540 positions even if no glyphs were produced (e.g., by a zero-width
16541 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16542 buffer positions that will be removed from the glyph row because
16544 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16545 column is beyond frame width: don't subtract 1 "pixel" when
16546 computing width of the stretch.
16547 (reseat_at_next_visible_line_start): Undo the change made on
16548 2011-09-17 that saved paragraph information and restored it after
16549 the call to `reseat'. (Bug#9545)
16551 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16553 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16554 and turn window cursor on if cleared (Bug#9415).
16556 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16558 * search.c (boyer_moore): Take unibyte characters from pattern
16559 literally. (Bug#9458)

16569 initialized, to pacify gcc -Wuninitialized.
16571 * fileio.c: Report proper errno when syscall falls.
16572 (Finsert_file_contents): Save and restore errno,
16573 so that report_file_error outputs the correct diagnostic.

16580 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16582 * xdisp.c (produce_stretch_glyph): Another fix for changes made on

16585 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16587 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16588 about the current paragraph and restore it after the call to reseat.
16590 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16591 (bidi_find_paragraph_start): Search back for paragraph beginning
16592 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16593 (bidi_move_to_visually_next): Only trigger paragraph-related
16594 computations when the last character is a newline or at EOB, not
16595 just any NEUTRAL_B. (Bug#9470)
16597 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16598 truncated lines if point is covered by a display string. (Bug#9524)
16600 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16602 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16603 (cons_to_x_long): New function.
16604 (lisp_data_to_selection_data): Use it. Correct the test for
16605 short-versus-long data; it was negated. Break out of vector
16606 loop, for efficiency, when a long datum is discovered.
16608 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16610 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16612 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16614 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see

16617 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16619 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16620 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16622 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>

16634 of TAB characters in a composition.
16636 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16638 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16639 This occurs when processing a multibyte format.
16640 Problem reported by Wolfgang Jenker.
16642 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16644 * xdisp.c (try_cursor_movement): Only check for exact match if
16645 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16647 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16649 Remove unused external symbols.
16650 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16651 * xdisp.c (calc_pixel_width_or_height): Now static.
16652 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.

16657 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16659 * xselect.c: Use signed conversions more consistently (Bug#9498).
16660 (selection_data_to_lisp_data): Assume incoming selection data are
16661 signed integers, not unsigned. This is to be consistent with
16662 outgoing selection data, which was modified to use signed integers
16663 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16664 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16665 expects long, not unsigned long.
16667 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16669 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16670 computation of loop end. Reported by Johan Bockgård
16673 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16675 * frame.c (Fother_visible_frames_p): Function deleted.
16677 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16679 * indent.c (compute_motion): Process display vector front to back
16680 rather than the other way around. (Bug#2496)
16682 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16684 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16686 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16688 * minibuf.c (Fread_from_minibuffer): Doc fix.
16690 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16692 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16693 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16695 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16697 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16698 value for non-existent files.
16700 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16702 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16703 set its "size" to -1. This will set the modtime_size field of
16704 the corresponding buffer to -1, which is what
16705 verify-visited-file-modtime expects for files that do not exist.
16708 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16710 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16712 * lisp.h: ... from here. push_key_description is no longer
16713 defined in keyboard.c, so its declaration should not be in
16714 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16715 logically belongs with push_key_description.
16717 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16719 * buffer.h: Include <sys/types.h> instead of <time.h>.
16720 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16721 Problem reported by Herbert J. Skuhra.
16723 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16725 * xml.c (parse_region): Make the parsing work for
16726 non-comment-starting XML files again (bug#9144).
16728 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16730 * image.c (gif_load): Fix calculation of bottom and right corner.
16733 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16735 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16736 redisplay in small windows.
16738 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16740 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16742 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16744 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16745 Operate on live windows only.
16747 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16749 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16751 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16753 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16754 only under bidi iteration.
16756 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16758 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16760 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16762 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16763 Without this fix, the command to link temacs failed due to an
16764 undefined symbol __builtin_isnan. This is because
16765 /usr/include/iso/math_c99.h #defines isnan(x) to
16766 __builtin_isnan(x), but the bundled gcc, which identifies itself
16767 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16769 * floatfns.c (isnan): #undef, and then #define to a clone of
16771 (Fisnan): Always define, since it's always available now.
16772 (syms_of_floatfns): Always define isnan at the Lisp level.
16774 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16776 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16778 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16780 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16781 The previous code assumed that file offsets (off_t values) fit in
16782 EMACS_INT variables, which is not true on typical 32-bit hosts.
16783 The code messed up by falsely reporting buffer overflow in cases
16784 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16785 when "big" contains more than 2**29 bytes, even though this
16786 inserts just one byte and does not overflow the buffer.
16787 (Finsert_file_contents): Store file offsets as off_t
16788 values, not as EMACS_INT values. Check for overflow when
16789 converting between EMACS_INT and off_t. When checking for
16790 buffer overflow or for overlap, take the offsets into account.
16791 Don't use EMACS_INT for small values where int suffices.
16792 When checking for overlap, fix a typo: ZV was used where
16793 ZV_BYTE was intended.
16794 (Fwrite_region): Don't assume off_t fits into 'long'.
16795 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16797 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16799 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16801 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16803 sprintf-related integer and memory overflow issues (Bug#9412).
16805 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16806 (esprintf, exprintf, evxprintf): New functions.
16807 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16808 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16809 (modify_event_symbol): Do not assume that the length of
16810 name_alist_or_stem is safe to alloca and fits in int.
16811 (Fexecute_extended_command): Likewise for function name and binding.
16812 (Frecursion_depth): Wrap around reliably on integer overflow.
16813 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16814 since some callers pass EMACS_INT values.
16815 (Fsingle_key_description): Don't crash if symbol name contains more
16816 than MAX_ALLOCA bytes.
16817 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16818 (get_minibuffer): Arg is now EMACS_INT, not int.
16819 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16820 (esprintf, exprintf, evxprintf): New decls.
16821 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16823 * dbusbind.c (signature_cat): New function.
16824 (xd_signature, Fdbus_register_signal):
16825 Do not overrun buffer; instead, report string overflow.
16827 * dispnew.c (add_window_display_history): Don't overrun buffer.
16828 Truncate instead; this is OK since it's just a log.
16830 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16831 even if the time zone offset is outlandishly large.
16832 Don't mishandle offset == INT_MIN.
16834 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16835 when creating daemon; the previous buffer-overflow check was incorrect.
16837 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16838 which has the guts of the old verror function.
16840 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16841 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16843 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16844 (font_unparse_xlfd): Don't blindly alloca long strings.
16845 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16846 fits in int, when using sprintf. Use single snprintf to count
16847 length of string rather than counting it via multiple sprintfs;
16848 that's simpler and more reliable.
16849 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16850 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16851 sprintf, in case result does not fit in int.
16853 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16854 (fontset_from_font): Print it.
16856 * frame.c (tty_frame_count): Now printmax_t, not int.
16857 (make_terminal_frame, set_term_frame_name): Print it.
16858 (x_report_frame_params): In X, window IDs are unsigned long,
16859 not signed long, so print them as unsigned.
16860 (validate_x_resource_name): Check for implausibly long names,
16861 and don't assume name length fits in 'int'.
16862 (x_get_resource_string): Don't blindly alloca invocation name;
16863 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16866 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16867 (xg_check_special_colors, xg_set_geometry):
16868 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16870 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16871 Use esprintf, not sprintf, in case result does not fit in int.
16873 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16874 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16875 it as a large positive number.
16876 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16877 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16879 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16880 in case result does not fit in int.
16882 * print.c (float_to_string): Detect width overflow more reliably.
16883 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16884 buffer overrun. Don't assume list length fits in 'int'. Treat
16885 print length of 0 as 0, not as infinity; to be consistent with other
16886 uses of print length in this function. Don't overflow print length
16887 index. Don't assume hash table size fits in 'long', or that
16888 vectorlike size fits in 'unsigned long'.
16890 * process.c (make_process): Use printmax_t, not int, to format
16891 process-name gensyms.
16893 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16895 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16896 to avoid potential buffer overrun.
16898 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16899 if X resource line is longer than 512 bytes.
16901 * xfns.c (x_window): Make sprintf buffer a bit bigger
16902 to avoid potential buffer overrun.
16904 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16906 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16908 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16910 Integer overflow fixes for scrolling, etc.
16911 Without these, Emacs silently mishandles large integers sometimes.
16912 For example, "C-u 4294967297 M-x recenter" was treated as if
16913 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16915 * xdisp.c (try_window_id): Check Emacs fixnum range before
16916 converting to 'int'.
16918 * window.c (window_scroll_line_based, Frecenter):
16919 Check that an Emacs fixnum is in range before assigning it to 'int'.
16920 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16921 values converted from Emacs fixnums.
16922 (Frecenter): Don't wrap around a line count if it is out of 'int'
16923 range; instead, treat it as an extreme value.
16924 (Fset_window_configuration, compare_window_configurations):
16925 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16927 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16928 that can exceed INT_MAX. Check that EMACS_INT value is in range
16929 before assigning it to the (possibly-narrower) index.
16930 (match_limit): Don't assume that a fixnum can fit in 'int'.
16932 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16935 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16936 (Fvertical_motion): Don't wrap around LINES values that don't fit
16937 in 'int'. Instead, treat them as extreme values. This is good
16938 enough for windows, which can't have more than INT_MAX lines anyway.
16940 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16942 * Require libxml/parser.h to avoid compilation warning.
16944 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16946 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16947 since this reportedly can destroy thread storage.
16949 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16951 * syntax.c (find_defun_start): Update all cache variables if
16952 exiting early (Bug#9401).
16954 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16956 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16958 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16959 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16960 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16962 * term.c (tty_append_glyph): New function.
16963 (produce_stretch_glyph): Static function and its prototype deleted.
16965 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16968 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16970 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16971 when checking :margin (Bug#9390).
16972 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16973 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16974 so that the name doesn't mislead. All uses changed.
16976 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16978 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16981 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16983 * xdisp.c (move_it_to): Don't bail out early when reaching
16984 position beyond to_charpos, if we are scanning backwards.
16985 (move_it_vertically_backward): When DY == 0, make sure we get to
16986 the first character in the line after the newline.
16988 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16990 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16991 (ccl_driver): Do not generate an out-of-range pointer.
16992 (Fccl_execute_on_string): Remove unnecessary check for
16993 integer overflow, noted by Stefan Monnier in
16994 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16995 Remove a FIXME that didn't need fixing.
16996 Simplify the newly-introduced buffer reallocation code.
16998 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
17000 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
17002 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
17004 Integer and memory overflow issues (Bug#9196).
17006 * doc.c (get_doc_string): Rework so that
17007 get_doc_string_buffer_size is the actual buffer size, rather than
17008 being 1 less than the actual buffer size; this makes xpalloc more
17011 * image.c (x_allocate_bitmap_record, cache_image):
17012 * xselect.c (Fx_register_dnd_atom):
17013 Simplify previous changes by using xpalloc.
17015 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
17016 since either will do and ptrdiff_t is convenient with xpalloc.
17018 * charset.c (charset_table_size)
17019 (struct charset_sort_data.priority): Now ptrdiff_t.
17020 (charset_compare): Don't overflow if priorities differ greatly.
17021 (Fsort_charsets): Don't assume list length fits in int.
17022 Check for size-calculation overflow when allocating sort data.
17023 (syms_of_charset): Allocate an initial charset table that is
17024 just under 64 KiB, to avoid problems with glibc malloc and mmap.
17026 * cmds.c (internal_self_insert): Check for size-calculation overflow.
17028 * composite.h (struct composition.glyph_len): Now int, not unsigned.
17029 The actual value is always <= INT_MAX, and leaving it unsigned made
17030 overflow checking harder.
17032 * dispextern.h (struct glyph_matrix.rows_allocated)
17033 (struct face_cache.size): Now ptrdiff_t, for convenience in use
17034 with xpalloc. The values are still always <= INT_MAX.
17036 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
17038 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
17039 (SAFE_NALLOCA): New macro.
17041 * region-cache.c (struct boundary.pos, find_cache_boundary)
17042 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
17043 (set_cache_region, invalidate_region_cache)
17044 (revalidate_region_cache, know_region_cache, region_cache_forward)
17045 (region_cache_backward, pp_cache):
17046 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
17047 so that ptrdiff_t * can be passed to xpalloc.
17048 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
17049 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
17050 (pp_cache): Don't assume cache_len fits in int.
17051 * region-cache.h: Adjust extern decls to match.
17053 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
17054 EMACS_INT, since either will do, for xpalloc.
17056 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
17057 (xnmalloc, xnrealloc, xpalloc): New functions.
17059 * bidi.c (bidi_shelve_header_size): New constant.
17060 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
17061 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
17063 * bidi.c (bidi_cache_shrink):
17064 * buffer.c (overlays_at, overlays_in, record_overlay_string)
17066 Don't update size of array until after memory allocation succeeds,
17067 because xmalloc/xrealloc may not return.
17068 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
17069 now that we have proper integer overflow checking.
17070 (record_overlay_string, overlay_strings): Catch overflows when
17071 calculating size of overlay_str_buf.
17073 * callproc.c (Fcall_process): Check for size overflow when
17074 calculating size of args2.
17075 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
17076 Normally we prefer signed values, but sticking with ptrdiff_t would
17077 require adding more-complicated checks.
17079 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
17080 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
17081 Redo buffer-overflow calculations to avoid integer overflow.
17082 Add a FIXME comment where memory seems to be over-allocated.
17084 * character.c (Fstring): Check for size-calculation overflow.
17086 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
17087 unnecessary integer overflow. Check for size overflow.
17088 (encode_coding_object): Don't update size until xmalloc succeeds.
17090 * composite.c (get_composition_id): Check for overflow in glyph
17091 length calculations.
17093 Integer and memory overflow fixes for display code.
17094 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
17095 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
17096 (scrolling_window): Check for overflow in size calculations.

17100 (row_table_size): Now ptrdiff_t, not int.
17101 (scrolling_window): Avoid overflow in size calculations.
17102 Don't update size until allocation succeeds.
17103 * fns.c (concat): Check for overflow in size calculations.
17104 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.

17108 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
17109 (get_doc_string): Check for size calculation overflow.
17110 Don't update size until allocation succeeds.
17111 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
17112 EMACS_INT, where ptrdiff_t will do.
17113 (Fsubstitute_command_keys): Check for string overflow.
17115 * editfns.c (set_time_zone_rule): Don't assume environment length
17117 (message_length): Now ptrdiff_t, not int.
17118 (Fmessage_box): Don't update size until allocation succeeds.
17119 Don't assume message length fits in int.
17120 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
17122 * emacs.c (main): Do not reallocate argv, since there is a null at
17123 the end that can be overwritten, and this way there's no need to
17124 worry about size-calculation overflow.
17125 (sort_args): Check for size-calculation overflow.
17127 * eval.c (init_eval_once, grow_specpdl): Don't update size until
17129 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
17131 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
17132 (x_set_scroll_bar_width, x_figure_window_size):
17133 Check for integer overflow.
17134 (x_set_alpha): Do not assume XINT fits in int.
17136 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
17137 This is for the members text_lines, text_cols, total_lines, total_cols,
17138 where the system imposes an 'int' limit.
17140 * fringe.c (Fdefine_fringe_bitmap):
17141 Don't update size until alloc works.
17143 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
17144 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
17146 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
17147 Check for size-calculation overflow.
17148 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
17149 do, as we prefer signed integers.
17150 (id_to_widget.max_size, id_to_widget.used)
17151 (xg_store_widget_in_map, xg_remove_widget_from_map)
17152 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
17153 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
17154 Use and return ptrdiff_t, not int.
17155 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
17156 * gtkutil.h: Change prototypes to match the above.
17158 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
17159 are duplicate now that they've been promoted to lisp.h.
17160 (x_allocate_bitmap_record, x_alloc_image_color)
17161 (make_image_cache, cache_image, xpm_load):
17162 Don't update size until alloc is done.
17163 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
17165 Check for size calculation overflow.
17166 (ct_colors_allocated_max): New constant.
17167 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

17172 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
17173 Use ptrdiff_t, not int, to count maps.
17174 (read_char_minibuf_menu_prompt): Check for overflow in size
17175 calculations. Don't update size until allocation succeeds.
17176 Redo calculations to avoid overflow.
17177 * keyboard.h: Change prototypes to match the above.
17179 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
17181 (current_minor_maps): Check for size calculation overflow.
17182 * keymap.h: Change prototypes to match the above.
17184 * lread.c (read1, init_obarray): Don't update size until alloc done.
17186 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
17187 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
17189 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
17190 Now ptrdiff_t, not int.
17191 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

17203 (Fset_match_data): Don't assume list lengths fit in 'int'.
17205 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
17206 for command line length. Do not attempt to address one before the
17207 beginning of an array, as that's not portable.
17209 * term.c (max_frame_lines): Remove; unused.
17210 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
17212 (encode_terminal_code, calculate_costs): Check for size
17213 calculation overflow.

17216 done. Redo calculations to avoid overflow.
17217 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
17219 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
17220 subtracting pointers.
17221 (gobble_line): Check for overflow more carefully. Don't update size
17224 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

17235 Use ptrdiff_t, not int, for sizes.
17236 (Finternal_make_lisp_face, cache_face):
17237 Check for size calculation overflow.
17238 (cache_face): Treat size calculation overflows as if they were
17239 memory exhaustion (the usual treatment), rather than aborting.
17241 * xfns.c (x_encode_text, x_set_name_internal)
17242 (Fx_change_window_property): Use ptrdiff_t, not int, to count
17243 sizes, since they can exceed INT_MAX in size. Check for size
17244 calculation overflow.
17246 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
17247 (xg_select): Check for size calculation overflow.
17248 Don't update size until alloc done.
17250 * xrdb.c (get_environ_db): Don't assume path length fits in int,
17251 as sprintf is limited to int lengths.
17253 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
17254 (X_LONG_MIN): New macros.
17255 Use them to make the following changes clearer.
17256 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
17257 This change doesn't affect the value now, but it may help remind
17258 future maintainers not to raise the value too much later.
17259 (SELECTION_QUANTUM): Remove, replacing with ...
17260 (selection_quantum): ... new function, which avoids overflow.
17262 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
17263 assumption that selection length fits in 'int'.
17264 (x_reply_selection_request, x_handle_selection_request)
17265 (x_get_window_property, receive_incremental_selection)
17266 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
17267 (lisp_data_to_selection_data, clean_local_selection_data):
17268 Use ptrdiff_t, not int, to record length of selection.
17269 (x_reply_selection_request, x_get_window_property)
17270 (receive_incremental_selection, x_property_data_to_lisp):
17271 Redo calculations to avoid overflow.
17272 (x_reply_selection_request): When sending hint, ceiling it at
17273 X_LONG_MAX rather than relying on wraparound overflow to send
17275 (x_get_window_property, receive_incremental_selection)
17276 (lisp_data_to_selection_data, x_property_data_to_lisp):
17277 Check for size-calculation overflow.
17278 (x_get_window_property, receive_incremental_selection)
17279 (lisp_data_to_selection_data, Fx_register_dnd_atom):
17280 Don't store size until memory allocation succeeds.
17281 (x_get_window_property): Plug memory leak on memory exhaustion.
17282 Don't double-block input; malloc is safe here. Don't assume 2**34
17283 - 4 fits in unsigned long. Add an xassert to check
17284 XGetWindowProperty overflow. Be more careful about overflow
17285 calculations, and distinguish size from memory overflow better.
17286 (receive_incremental_selection): When tracing, don't assume
17287 unsigned int is less than INT_MAX.
17288 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
17289 harmful) conversions of unsigned short to int.
17290 (lisp_data_to_selection_data): Don't assume that integers
17291 in the range -65535 through -1 fit in an X unsigned short.
17292 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17293 result parameters unless successful. Rely on cons_to_unsigned
17294 to report problems with elements; the old code wasn't right anyway.
17295 (x_check_property_data): Check for int overflow; we cannot use
17296 a wider type due to X limits.
17297 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
17299 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
17301 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
17302 (x_term_init): Check for size calculation overflow.
17303 (x_color_cells): Don't store size until memory allocation succeeds.
17304 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.

17328 * image.c (xpm_get_color_table_h):
17329 * lisp.h (hash_lookup, hash_put):
17330 * minibuf.c (Ftest_completion):
17331 Use ptrdiff_t for hash table indexes, not int (which is too
17332 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17333 32-bit --with-wide-int hosts).
17335 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17336 Add a FIXME comment about memory leaks.
17337 (syms_of_charset): Don't assume xmalloc returns.
17339 Don't assume that stated character widths fit in int.
17340 * character.c (Fchar_width, c_string_width, lisp_string_width):
17341 * character.h (CHAR_WIDTH):
17342 * indent.c (MULTIBYTE_BYTES_WIDTH):
17343 Use sanitize_char_width to avoid undefined and/or bad behavior
17344 with outlandish widths.
17345 * character.h (sanitize_tab_width): Rename from sanitize_width,
17346 now that we have two such functions. All uses changed.
17347 (sanitize_char_width): New inline function.
17349 Don't assume that tab-width fits in int.
17350 * character.h (sanitize_width): New inline function.
17351 (SANE_TAB_WIDTH): New macro.
17352 (ASCII_CHAR_WIDTH): Use it.

17357 * fileio.c: Integer overflow issues with file modes.
17358 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
17360 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
17361 Remove unreachable code.
17362 (read_hex, load_charset_map_from_file): Check for integer overflow.
17364 * xterm.c: Don't go over XClientMessageEvent limit.
17365 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17366 (x_send_scroll_bar_event): Likewise. Check that the size does not
17367 exceed limits imposed by XClientMessageEvent, as well as the usual
17368 ptrdiff_t and size_t limits.
17370 * keyboard.c: Overflow, signedness and related fixes.
17371 (make_lispy_movement): Use same integer type in forward decl
17372 that is used in the definition.
17373 (read_key_sequence, keyremap_step):
17374 Change bufsize argument back to int, undoing my 2011-03-30 change.
17375 We prefer signed types, and int is wide enough here.
17376 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17377 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17378 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17379 length, not size_t. Use ptrdiff_t for index, not int.
17380 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17381 possibility of integer overflow.
17383 Overflow, signedness and related fixes for images.
17385 * dispextern.h (struct it.stack[0].u.image.image_id)
17386 (struct_it.image_id, struct image.id, struct image_cache.size)

17393 * xdisp.c (calc_pixel_width_or_height):
17394 * xfns.c (image_cache_refcount):
17395 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
17396 on typical 64-bit hosts.

17402 when the callers expect that.
17403 (image_ascent): Redo ascent calculation to avoid int overflow.
17404 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
17405 (lookup_image): Remove unnecessary tests.
17406 (xbm_image_p): Locals are now of int, not EMACS_INT,
17407 since parse_image_check makes sure they fit into int.
17408 (png_load, gif_load, svg_load_image):
17409 Prefer int to unsigned where either will do.
17410 (tiff_handler): New function, combining the cores of the
17411 old tiff_error_handler and tiff_warning_handler.
17412 This function is rewritten to use vsnprintf and thereby avoid
17413 stack buffer overflows. It uses only the features of vsnprintf
17414 that are common to both POSIX and native Microsoft.
17415 (tiff_error_handler, tiff_warning_handler): Use it.
17416 (tiff_load, gif_load, imagemagick_load_image):
17417 Don't assume :index value fits in 'int'.
17418 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17419 (imagemagick_load_image): Check that crop parameters fit into
17420 the integer types that MagickCropImage accepts. Don't assume
17421 Vimagemagick_render_type has a nonnegative value. Don't assume
17422 size_t fits in 'long'.
17423 (gs_load): Use printmax_t to print the widest integers possible.
17424 Check for integer overflow when computing image height and width.

17434 the display spec is of the form `(space ...)'.
17435 (handle_display_spec): Return the value returned by
17436 handle_single_display_spec, not just 1 or zero.
17437 (handle_single_display_spec): If the display spec is of the form
17438 `(space ...)', and specifies display in the text area, return 2
17440 (try_cursor_movement): Check for the need to scroll more
17441 accurately, and prefer exact match for point under bidi.
17442 Don't advance `row' beyond the last row of the window.
17444 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
17445 into disp_prop; all users changed.
17447 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
17448 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
17449 for the text covered by the display property.

17459 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
17460 buffers, return left-to-right.
17461 (set_cursor_from_row): Consider candidate row a win if its glyph
17462 represents a newline and point is on that newline. Fixes cursor
17463 positioning on the newline at EOL of R2L text within L2R
17464 paragraph, and vice versa.
17465 (try_cursor_movement): Check continued rows, in addition to
17466 continuation rows. Fixes unwarranted scroll when point enters a
17467 continued line of R2L text within an L2R paragraph, or vice versa.
17468 (cursor_row_p): Consider the case of point being equal to
17469 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
17470 from the end of a short line to the beginning of a continued line
17471 of R2L text within L2R paragraph.
17472 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
17473 composed characters.
17475 * bidi.c (bidi_check_type): Use xassert.
17476 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
17479 2011-08-23 Eli Zaretskii <eliz@gnu.org>

17486 * nsfont.m (ns_otf_to_script): Fix typo.
17488 2011-08-22 Kenichi Handa <handa@m17n.org>
17490 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
17491 extra slot even if the purpose is char-code-property-table.
17493 2011-08-23 Eli Zaretskii <eliz@gnu.org>
17495 * xdisp.c (redisplay_window): When computing centering_position,
17496 account for the height of the header line. (Bug#8874)
17498 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17499 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17500 candidate is selected by the mouse, and that candidate has a
17501 composed character under the mouse.
17503 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17504 coordinates reported by pos-visible-in-window-p for a composed
17505 character in column zero.
17507 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
17509 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
17511 2011-08-22 Eli Zaretskii <eliz@gnu.org>
17513 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
17514 consider it a hit if to_charpos is anywhere in the range of the
17515 composed buffer positions.
17517 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17519 * image.c (gif_load): Don't assume that each subimage has the same
17520 dimensions as the base image. Handle disposal method that is
17521 "undefined" by the gif spec (Bug#9335).
17523 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17525 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
17526 (Fcondition_case): Document `debug' symbol in error handler.
17528 2011-08-19 Eli Zaretskii <eliz@gnu.org>
17530 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
17531 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17532 from an Org mode buffer to a Speedbar frame.
17534 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17535 a composition, take its buffer position from IT->cmp_it.charpos.
17536 Fixes cursor positioning at the beginning of a line that begins
17537 with a composed character.
17539 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17541 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17542 character bidirectional type, use STRONG_L instead. Fixes crashes
17543 in a buffer produced by `describe-categories'.
17545 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17546 members before the level stack, so they would be saved and
17547 restored when copying iterator state. Fixes incorrect reordering
17548 around TABs covered by display properties.
17550 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17552 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

17557 (internal_condition_case_2, internal_condition_case_n):
17558 Remove unnecessary aborts (Bug#9081).
17560 2011-08-17 Eli Zaretskii <eliz@gnu.org>
17562 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
17563 has no `load' handler, try opening the file locally. (Bug#9311)
17565 2011-08-16 Ken Brown <kbrown@cornell.edu>
17567 * gmalloc.c: Expand comment.
17569 2011-08-16 Eli Zaretskii <eliz@gnu.org>
17571 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
17572 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.

17620 2011-08-14 Eli Zaretskii <eliz@gnu.org>
17622 * xdisp.c (move_it_in_display_line_to): Don't invoke
17623 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17624 ppos_it. Fixes vertical cursor motion when line beginning is
17625 covered by an image. (Bug#9296)
17627 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17629 * nsterm.h (ns_run_ascript): Declare.

17633 (ns_run_ascript): New function.
17634 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17635 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17636 the event loop. Get status from as_status (Bug#7276).
17638 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17639 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17640 the event loop (Bug#7276).
17642 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

17666 (Fnetwork_interface_list): Allocate in increments of bytes instead
17667 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17668 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17670 (struct ifflag_def): notrailers is smart on OSX.
17671 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17672 Get hardware address with getifaddrs if available.
17674 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17676 * xdisp.c (iterate_out_of_display_property): xassert that
17677 IT->position is set to within IT->object's boundaries. Break from

17680 Set IT->current to match the bidi iterator unconditionally.
17681 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17682 entry. Force push_it to save on the stack the current
17683 buffer/string position, to be restored by pop_it. Fix flags in
17684 the iterator structure wrt the object coming from a display
17685 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17686 properties. (Bug#9284)
17688 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17690 * fontset.c (fontset_get_font_group): Add proper type checks.

17715 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
17717 * composite.c (autocmp_chars): Don't reset point. That is done by
17718 restore_point_unwind (Bug#5984).
17720 2011-08-07 Juri Linkov <juri@jurta.org>
17722 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17723 to show the arg `TIME' instead of `TIMEVAL'.
17725 2011-08-06 Eli Zaretskii <eliz@gnu.org>
17727 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17728 display property strides EOL and includes a newline, as in
17729 longlines-mode. (Bug#9254)
17730 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17731 word-wrap under bidirectional display. (Bug#9224)
17733 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17734 is non-zero, even if the data buffer is NULL. Fixes a crash in
17735 vertical-motion with longlines-mode. (Bug#9254)
17737 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17739 * bidi.c <bidi_cache_total_alloc>: Now static.

17745 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17746 amount allocated this far in `bidi_cache_total_alloc'.
17747 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17748 non-zero, only free the data buffer without restoring the cache
17749 contents. All callers changed.
17751 * dispextern.h (bidi_unshelve_cache): Update prototype.
17753 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17754 (move_it_in_display_line, move_it_to)
17755 (move_it_vertically_backward, move_it_by_lines): Replace the call
17756 to xfree to an equivalent call to bidi_unshelve_cache.
17757 (move_it_in_display_line_to): Fix logic of returning
17758 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17760 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17762 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
17763 came from a string character with a `cursor' property. (Bug#9229)

17777 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17779 * xterm.c (x_find_topmost_parent): New function.
17780 (x_set_frame_alpha): Find topmost parent window with
17781 x_find_topmost_parent and set the property there also (bug#9181).
17782 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
17784 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
17786 * callproc.c (Fcall_process): Avoid vfork clobbering
17787 the local vars buffer, coding_systems, current_dir.
17789 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
17791 * keymap.c (Fmake_composed_keymap): Move to subr.el.
17793 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
17795 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
17796 so that it is not optimized away.
17798 * xdisp.c (compute_display_string_pos): Remove unused local.
17800 2011-08-02 Eli Zaretskii <eliz@gnu.org>
17802 Fix slow cursor motion and scrolling in large buffers with
17803 selective display, like Org Mode buffers. (Bug#9218)
17805 * dispextern.h (struct bidi_it): New member disp_prop_p.
17807 * xdisp.c: Remove one-slot cache of display string positions.
17808 (compute_display_string_pos): Accept an additional argument
17809 DISP_PROP_P; callers changed. Scan at most 5K characters forward
17810 for a display string or property. If found, set DISP_PROP_P
17813 * bidi.c (bidi_fetch_char): Accept an additional argument
17814 DISP_PROP_P, and pass it to compute_display_string_pos.
17815 Only handle text covered by a display string if DISP_PROP_P is returned
17816 non-zero. All callers of bidi_fetch_char changed.
17818 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17820 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17822 2010-12-03 Don March <don@ohspite.net>
17824 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17825 last character M-[char] is translated to ESC [char] (bug#7541).
17827 2011-08-02 Kenichi Handa <handa@m17n.org>
17829 * lisp.h (uniprop_table): Extern it.
17831 * chartab.c (uniprop_table): Make it non-static.
17833 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17835 * xdisp.c (forward_to_next_line_start): Accept additional argument
17836 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17838 (reseat_at_next_visible_line_start): Use the bidi iterator state
17839 returned by forward_to_next_line_start to restore the state of
17840 it->bidi_it after backing up to previous newline. (Bug#9212)
17842 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17844 * regex.c (re_comp): Protoize.
17845 (re_exec): Fix return type.
17846 (regexec): Fix type of `ret'. (Bug#9203)
17848 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17850 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17851 This is needed if max-image-size is a floating-point number.
17853 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17855 * print.c (print_object): Print empty symbol as ##.
17857 * lread.c (read1): Read ## as empty symbol.
17859 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17861 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17862 setting frame foreground color (Bug#9175).
17863 (x_set_background_color): Likewise.
17865 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17866 contents (Bug#9176).
17867 (EmacsTooltip -init): Remove bezels and add shadows to
17870 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17871 or scroll bar (Bug#8470).
17873 * nsfont.m (nsfont_open): Remove assignment to voffset and
17874 unnecessary vars hshink, expand, hd, full_height, min_height.
17875 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17877 * nsterm.h (nsfont_info): Remove voffset field.
17879 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17881 Implement strike-through and overline on NextStep (Bug#8863).
17883 * nsfont.m (nsfont_open): Use underline position provided by font,
17884 instead of hard-coded value of 2.
17885 (nsfont_draw): Call ns_draw_text_decoration instead.
17887 * nsterm.h: Add declaration for ns_draw_text_decoration.
17889 * nsterm.m (ns_draw_text_decoration): New function for drawing
17890 underline, overline, and strike-through.
17891 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17892 ns_draw_text_decoration. Change treatment of cursor drawing to
17893 accommodate underlining, etc.
17895 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17897 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17900 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17902 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17903 Without this fix, if a signal arrives just after memory fills up,
17904 'malloc' might be invoked reentrantly.
17906 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17907 In other words, assume that every image size is allowed, on non-X
17908 hosts. This assumption is probably wrong, but it lets Emacs compile.
17910 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17912 * regex.c (re_iswctype): Convert return values to boolean.
17914 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17916 * xdisp.c (compute_display_string_pos): Don't use cached display
17917 string position if the buffer had its restriction changed.
17920 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17922 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17924 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17926 Integer signedness and overflow and related fixes. (Bug#9079)
17928 * bidi.c: Integer size and overflow fixes.
17929 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17930 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17931 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17932 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17933 (bidi_find_other_level_edge):
17934 Use ptrdiff_t instead of EMACS_INT where either will do.
17935 This works better on 32-bit hosts configured --with-wide-int.
17936 (bidi_cache_ensure_space): Check for size-calculation overflow.
17937 Use % rather than repeated addition, for better worst-case speed.
17938 Don't set bidi_cache_size until after xrealloc returns, because it
17940 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17941 (bidi_cache_ensure_space): Also check that the bidi cache size
17942 does not exceed that of the largest Lisp string or buffer. See Eli
17943 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17945 * alloc.c (__malloc_size_t): Remove.
17946 All uses replaced by size_t. See Andreas Schwab's note
17947 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17949 * image.c: Improve checking for integer overflow.
17950 (check_image_size): Assume that f is nonnull, since
17951 it is always nonnull in practice. This is one less thing to
17952 worry about when checking for integer overflow later.
17953 (x_check_image_size): New function, which checks for integer
17954 overflow issues inside X.
17955 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17956 This removes the need for a memory_full check.
17957 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17958 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17959 (xbm_read_bitmap_data): Change locals back to 'int', since
17960 their values must fit in 'int'.
17961 (xpm_load_image, png_load, tiff_load):
17962 Invoke x_create_x_image_and_pixmap earlier,
17963 to avoid much needless work if the image is too large.
17964 (tiff_load): Treat overly large images as if
17965 x_create_x_image_and_pixmap failed, not as malloc failures.
17966 (gs_load): Use x_check_image_size.
17968 * gtkutil.c: Omit integer casts.
17969 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17970 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17972 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17974 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17975 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17976 would wrongly return t on a 64-bit host.
17978 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17979 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17980 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17981 and therefore cause GCC to emit a bogus diagnostic in some cases.
17983 * image.c: Integer signedness and overflow and related fixes.
17984 This is not an exhaustive set of fixes, but it's time to
17985 record what I've got.
17986 (lookup_pixel_color, check_image_size): Remove redundant decls.
17987 (check_image_size): Don't assume that arbitrary EMACS_INT values
17988 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17989 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17990 (tiff_load, imagemagick_load_image):
17991 Check for overflow in size calculations.
17992 (x_create_x_image_and_pixmap): Remove unnecessary test for
17993 xmalloc returning NULL; that can't happen.
17994 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17995 (xpm_color_bucket): Use better integer hashing function.
17996 (xpm_cache_color): Don't possibly over-allocate memory.
17997 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17998 (gif_memory_source):
17999 Use ptrdiff_t, not int or size_t, to record sizes.
18000 (png_load): Don't assume values greater than 2**31 fit in 'int'.
18001 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
18002 either works, as we prefer signed integers.
18003 (tiff_read_from_memory, tiff_write_from_memory):
18004 Return tsize_t, not size_t, since that's what the TIFF API wants.
18005 (tiff_read_from_memory): Don't fail simply because the read would
18006 go past EOF; instead, return a short read.
18007 (tiff_load): Omit no-longer-needed casts.
18008 (Fimagemagick_types): Don't assume size fits into 'int'.
18010 Improve hashing quality when configured --with-wide-int.
18011 * fns.c (hash_string): New function, taken from sxhash_string.
18012 Do not discard information about ASCII character case; this
18013 discarding is no longer needed.
18014 (sxhash-string): Use it. Change sig to match it. Caller changed.
18015 * lisp.h: Declare it.
18016 * lread.c (hash_string): Remove, since we now use fns.c's version.
18017 The fns.c version returns a wider integer if --with-wide-int is
18018 specified, so this should help the quality of the hashing a bit.
18020 * emacs.c: Integer overflow minor fix.
18021 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
18022 Define only if GNU_LINUX.
18023 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
18025 * dispnew.c: Integer signedness and overflow fixes.
18026 Remove unnecessary forward decls, that were a maintenance hassle.
18027 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
18029 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
18030 (scrolling_window): Use ptrdiff_t, not int, for byte count.
18031 (prepare_desired_row, line_draw_cost):
18032 Use int, not unsigned, where either works.
18033 (save_current_matrix, restore_current_matrix):
18034 Use ptrdiff_t, not size_t, where either works.
18035 (init_display): Check for overflow more accurately, and without
18036 relying on undefined behavior.
18038 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
18039 Remove, replacing with the new symbols in lisp.h. All uses changed.
18040 * fileio.c (make_temp_name):
18041 * filelock.c (lock_file_1, lock_file):
18042 * xdisp.c (message_dolog):
18043 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
18044 Use pMd etc. instead.
18045 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
18046 replacing the pWIDE etc. symbols removed from editfns.c.
18048 * keyboard.h (num_input_events): Now uintmax_t.
18049 This is (very slightly) less likely to mess up due to wraparound.
18052 * buffer.c: Integer signedness fixes.
18053 (alloc_buffer_text, enlarge_buffer_text):
18054 Use ptrdiff_t rather than size_t when either will do, as we prefer
18057 * alloc.c: Integer signedness and overflow fixes.
18058 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
18059 (__malloc_size_t): Default to size_t, not to int.
18060 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
18061 (Fgarbage_collect, mark_object_loop_halt, mark_object):
18062 Prefer ptrdiff_t to size_t when either would do, as we prefer
18064 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
18065 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
18066 Now const. Initialize with values that are in range even if char
18068 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
18069 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
18070 These functions do the right thing with sizes > 2**32.
18071 (check_depth): Now ptrdiff_t, not int.
18072 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
18073 Adjust to new way of storing sizes. Check for size overflow bugs
18075 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
18076 slightly wrong anyway, as it missed one instance of
18077 XMALLOC_OVERRUN_CHECK_OVERHEAD.
18078 (refill_memory_reserve): Omit needless cast to size_t.
18079 (mark_object_loop_halt): Mark as externally visible.
18081 * xselect.c: Integer signedness and overflow fixes.
18082 (Fx_register_dnd_atom, x_handle_dnd_message):
18083 Use ptrdiff_t, not size_t, since we prefer signed.
18084 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
18085 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
18086 x_dnd_atoms_size and x_dnd_atoms_length.
18088 * doprnt.c: Prefer signed to unsigned when either works.
18090 * doprnt.c (doprnt):
18092 * xdisp.c (vmessage):
18093 Use ptrdiff_t, not size_t, when using or implementing doprnt,
18094 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
18095 prefer signed arithmetic to avoid comparison confusion.
18096 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
18097 but is a bit tricky.
18099 Assume freestanding C89 headers, string.h, stdlib.h.
18100 * data.c, doprnt.c, floatfns.c, print.c:
18101 Include float.h unconditionally.
18102 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
18103 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
18104 * regex.c: Likewise for stddef.h, string.h.
18105 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
18106 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
18107 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
18108 (STDC_HEADERS): Remove obsolete defines.
18109 * sysdep.c: Include limits.h unconditionally.
18111 Assume support for memcmp, memcpy, memmove, memset.
18112 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
18113 * regex.c (memcmp, memcpy):
18114 Remove; we assume C89 now.
18116 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
18117 (__malloc_safe_bcopy): Remove; no longer needed.
18119 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
18120 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
18121 well either way, and we prefer signed to unsigned.
18123 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
18125 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
18126 closes the connection while we're reading (bug#9182).
18128 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
18130 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
18131 are specified (Bug#9168).
18133 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
18135 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
18136 Found by GCC static checking and --with-wide-int on a 32-bit host.
18138 2011-07-25 Eli Zaretskii <eliz@gnu.org>
18140 * xdisp.c (compute_display_string_pos): Fix logic of caching
18141 previous display string position. Initialize cached_prev_pos to
18142 -1. Fixes slow-down at the beginning of a buffer.
18144 2011-07-24 Eli Zaretskii <eliz@gnu.org>
18146 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
18147 for attrs[LFACE_FONTSET_INDEX].
18149 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
18151 * xml.c (parse_region): Remove unused local
18152 that was recently introduced.
18154 2011-07-23 Eli Zaretskii <eliz@gnu.org>
18156 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
18157 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
18159 * xdisp.c (move_it_in_display_line_to): Record the best matching
18160 position for TO_CHARPOS while scanning the line, and restore it on
18161 exit if none of the characters scanned was an exact match.
18162 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
18163 when exact match is impossible due to invisible text, and the
18164 lines are truncated.
18166 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
18168 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
18171 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18173 Fix a significant slow-down of cursor motion with C-n, C-p,
18174 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
18175 auto-repeat under bidi redisplay in fontified buffers.
18176 * xdisp.c (compute_stop_pos_backwards): New function.
18177 (next_element_from_buffer): Call compute_stop_pos_backwards to
18178 find a suitable prev_stop when we find ourselves before
18180 (reseat): Don't look for prev_stop, as that could mean a very long
18182 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
18183 <cached_disp_overlay_modiff>: Cache for last found display string
18185 (compute_display_string_pos): Return the cached position if asked
18186 about the same buffer in the same area of character positions, and
18187 the buffer wasn't changed since the time the display string
18188 position was cached.
18190 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18192 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
18193 is an integer, which is important for empty lines. (Bug#9149)
18195 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
18197 * frame.c (Fmodify_frame_parameters): In tty case, update the
18198 default face if necessary (Bug#4238).
18200 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
18202 * editfns.c (Fstring_to_char): No need to explain what a character
18203 is in the docstring (Bug#6576).
18205 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18207 * xml.c (parse_region): Make sure we always return a tree.
18209 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
18211 * xml.c (parse_region): If a document contains only comments,
18214 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18216 * xml.c (make_dom): Return comments, too.
18218 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
18221 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
18222 and the surrounding thread.
18223 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
18224 rather than fgets, and retry after EINTR. Otherwise, 'emacs
18225 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
18227 * s/openbsd.h (BROKEN_SIGIO): Define.
18228 * unexelf.c (unexec) [__OpenBSD__]:
18229 Don't update the .mdebug section of the Alpha COFF symbol table.
18231 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
18233 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
18236 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
18238 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
18239 This fixes some race conditions on the permissions of any newly
18242 * alloc.c (valid_pointer_p): Use pipe, not open.
18243 This fixes some permissions issues when debugging.
18245 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
18246 If fchown fails to set both uid and gid, try to set just gid,
18247 as that is sometimes allowed. Adjust the file's mode to eliminate
18248 setuid or setgid bits that are inappropriate if fchown fails.
18250 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
18252 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
18253 to compare Lisp_Objects.

18258 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
18260 * lread.c (read_integer): Unread even EOF character.
18261 (read1): Likewise. Properly record start position of symbol.

18264 symbol character follows.
18266 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
18268 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
18269 This works around a problem with the previous change to Fcopy_file.
18270 Recent glibc declares fchown with __attribute__((warn_unused_result)),
18271 and without this change, GCC might complain about discarding
18272 fchown's return value.
18274 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
18276 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
18278 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
18280 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
18282 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
18284 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
18285 it's used from the C level.
18287 * process.c: Use the same condition for POLL_FOR_INPUT in both
18288 keyboard.c and process.c (bug#1858).
18290 2011-07-09 Lawrence Mitchell <wence@gmx.li>
18292 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
18293 (Fgnutls_boot): Use it.
18295 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
18297 * doc.c (Fsubstitute_command_keys): Revert last change.
18299 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18301 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18302 quotes the next character, and doesn't affect other longer
18303 sequences (bug#8935).
18305 * lread.c (syms_of_lread): Clarify that is isn't only
18306 `eval-buffer' and `eval-defun' that's affected by
18307 `lexical-binding' (bug#8460).
18309 2011-07-15 Eli Zaretskii <eliz@gnu.org>
18311 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18312 bidi redisplay when a line includes both an image and is truncated.
18314 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18316 Fix minor problems found by static checking.
18317 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18318 (elsz): Now a signed constant, not a size_t var. We prefer signed
18319 types to unsigned, to avoid integer comparison confusion. Without
18320 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18321 "cannot optimize loop, the loop counter may overflow", a symptom
18323 * indent.c (Fvertical_motion): Mark locals as initialized.
18324 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18326 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
18328 * search.c (Fre_search_backward): Mention `case-fold-search' in
18329 all the re_search_* functions (bug#8138).
18331 * keyboard.c (Fopen_dribble_file): Document when the file is

18352 (display_string): If we need to ignore text properties of
18353 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
18354 original value of -1 will not work with bidi.)
18355 (compute_display_string_pos): First arg is now struct
18356 `text_pos *'; all callers changed. Support display properties on
18358 (compute_display_string_end): Support display properties on Lisp
18360 (init_iterator, reseat_1, reseat_to_string): Initialize the
18361 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
18362 when iterating on a string not from display properties).
18363 (compute_display_string_pos, compute_display_string_end):
18364 Fix calculation of the object to scan. Fixes an error when using
18366 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
18367 base_level_stop; instead, set base_level_stop to BEGV.
18368 Fixes crashes in vertical-motion.
18369 (next_element_from_buffer): Improve commentary for when
18370 the iterator is before prev_stop.
18371 (init_iterator): Initialize bidi_p from the default value of
18372 bidi-display-reordering, not from buffer-local value. Use the
18373 buffer-local value only if initializing for buffer iteration.

18382 Use IT_STRING_CHARPOS when displaying from a Lisp string.
18383 (init_iterator): Don't initialize it->bidi_p for strings
18385 (reseat_to_string): Initialize it->bidi_p for strings here.

18393 (get_visually_first_element): New function, refactored from common
18394 parts of next_element_from_buffer, next_element_from_string, and
18395 next_element_from_c_string.
18396 (tool_bar_lines_needed, redisplay_tool_bar)
18397 (display_menu_bar): Force left-to-right direction. Add a FIXME
18398 comment for making that be controlled by a user option.

18407 (get_overlay_strings_1, push_display_prop): Set up the bidi
18408 iterator for displaying display or overlay strings.
18409 (forward_to_next_line_start): Don't use the shortcut if
18411 (back_to_previous_visible_line_start): If handle_display_prop
18412 pushed the iterator stack, restore the internal state of the bidi
18413 iterator by calling bidi_pop_it same number of times.
18414 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
18415 and we are bidi-iterating, don't decrement the iterator position;
18416 instead, set the first_elt flag in the bidi iterator, to produce
18418 (reseat_1): Remove redundant setting of string_from_display_prop_p.
18419 (push_display_prop): xassert that we are iterating a buffer.

18423 (push_display_prop): Set up the `unibyte' member of bidi_it.string
18424 correctly. Don't assume unibyte strings are not bidi-reordered.

18433 property. Fix a typo in popping stretch info. Add an assertion
18434 for verifying that the iterator position is in sync with the bidi
18436 (handle_single_display_spec, get_overlay_strings_1)

18461 displayed in margins. (Bug#8133) (Bug#8867)
18462 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past

18526 (struct iterator_stack_entry): New members bidi_p,
18527 paragraph_embedding, and from_disp_prop_p.

18848 (clone_per_buffer_values): Don't assume that

18850 This isn't true in general, and it's particularly not true
18851 if Emacs is configured with --with-wide-int.
18852 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
18853 New macros, used in the buffer.c change.

18889 Random fixes. E.g., (random) never returned negative values.
18890 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18891 subseconds part to the entropy, as that's a bit more random.
18892 Prefer signed to unsigned, since the signedness doesn't matter and
18893 in general we prefer signed. When given a limit, use a
18894 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18895 latter isn't right if USE_2_TAGS_FOR_INTS.
18896 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18897 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18909 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18910 This is more efficient than Ffile_directory_p and avoids a minor race.
18912 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18914 * buffer.c (Foverlay_put): Say what the return value is
18917 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18918 is a directory before asking whether to use the file name

18921 error be more correct.
18923 * fns.c (Frequire): Remove the mention of the .gz files, since
18924 that's installation-specific, but keep the mention of
18925 `get-load-suffixes'.

18929 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

18940 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18941 Also (re)move comments that are misplaced or no longer relevant.

18970 * lread.c (syms_of_lread): Mention single symbols defined by

19042 * eval.c (struct backtrace): Simplify and port the data structure.
19043 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
19044 signed bit field, as this assumption is not portable and it makes
19045 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
19046 "char debug_on_exit : 1" as this is not portable either; instead,
19047 use the portable "unsigned int debug_on_exit : 1". Remove unused
19048 member evalargs. Remove obsolete comments about cc bombing out.
19050 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

19117 (get_parent_class, emacs_fixed_set_min_size): Remove.
19118 (emacs_fixed_new): Set priv->f to argument.
19119 (emacs_fixed_get_preferred_width)
19120 (emacs_fixed_get_preferred_height): Use min_width/height from
19121 frames size_hint to set minimum and natural (Bug#8919).
19122 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
19123 and use min_width/height from frames size_hint to set
19124 min_width/height (Bug#8919).
19126 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
19127 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.
19130 2011-06-26 Eli Zaretskii <eliz@gnu.org>
19132 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
19133 bidi_at_paragraph_end, since fast_looking_at doesn't like to be
19136 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
19138 * process.c (wait_reading_process_output): Bypass select if
19139 waiting for a cell while ignoring keyboard input, and input is
19140 pending. Suggested by Jan Djärv (Bug#8869).
19142 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
19144 Use gnulib's dup2 module instead of rolling our own.
19145 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
19147 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19149 * dispnew.c (scrolling_window): Before scrolling, turn off a

19212 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
19214 Integer and buffer overflow fixes (Bug#8873).
19216 * print.c (printchar, strout): Check for string overflow.
19217 (PRINTPREPARE, printchar, strout):
19218 Don't set size unless allocation succeeds.
19220 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
19221 for sizes. Check for string overflow more accurately.
19222 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
19224 * macros.c: Integer and buffer overflow fixes.
19225 * keyboard.h (struct keyboard.kbd_macro_bufsize):
19226 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
19227 Use ptrdiff_t, not int, for sizes.
19228 Don't increment bufsize until after realloc succeeds.
19229 Check for size-calculation overflow.
19230 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
19232 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
19234 * lread.c: Integer overflow fixes.
19235 (read_integer): Radix is now EMACS_INT, not int,
19236 to improve quality of diagnostics for out-of-range radices.
19237 Calculate buffer size correctly for out-of-range radices.
19238 (read1): Check for integer overflow in radices, and in
19239 read-circle numbers.
19240 (read_escape): Avoid int overflow.
19241 (Fload, openp, read_buffer_size, read1)
19242 (substitute_object_recurse, read_vector, read_list, map_obarray):
19243 Use ptrdiff_t, not int, for sizes.

19258 2011-06-22 Leo Liu <sdl.web@gmail.com>
19260 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
19261 Move to minibuffer.el.
19263 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19265 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
19266 The following patches are for when GLYPH_DEBUG && !XASSERT.
19267 * dispextern.h (trace_redisplay_p, dump_glyph_string):
19268 * dispnew.c (flush_stdout):
19269 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
19270 Mark as externally visible.
19271 * dispnew.c (check_window_matrix_pointers): Now static.
19272 * dispnew.c (window_to_frame_vpos):
19273 * xfns.c (unwind_create_frame):
19274 * xterm.c (x_check_font): Remove unused local.
19275 * scroll.c (CHECK_BOUNDS):
19276 * xfaces.c (cache_fache): Rename local to avoid shadowing.
19277 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
19278 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
19279 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
19280 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
19282 (debug_method_add): Use va_list and vsprintf rather than relying
19283 on undefined behavior with wrong number of arguments.
19284 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19285 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19286 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19287 since we're not interested in debugging glyphs with old libraries.
19288 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19289 GCC 4.6.0's static checking.
19291 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19293 Integer overflow and signedness fixes (Bug#8873).

19302 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
19303 (x_create_bitmap_from_xpm_data):
19304 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
19305 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
19307 * xfaces.c (load_pixmap):

19309 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
19310 (.bitmaps_last, struct x_output.icon_bitmap):
19311 Use ptrdiff_t, not int, for bitmap indexes.
19312 (x_allocate_bitmap_record): Check for size overflow.
19313 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
19315 Use ptrdiff_t, not int, for overlay counts.
19316 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
19317 * editfns.c (overlays_around, get_pos_property):
19318 * textprop.c (get_char_property_and_overlay):
19319 * xdisp.c (next_overlay_change, note_mouse_highlight):
19320 * xfaces.c (face_at_buffer_position):
19321 * buffer.c (OVERLAY_COUNT_MAX): New macro.
19322 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
19323 (Fnext_overlay_change, Fprevious_overlay_change)
19324 (mouse_face_overlay_overlaps, Foverlays_in):
19325 Use ptrdiff_t, not int, for sizes.
19326 (overlays_at, overlays_in): Check for size-calculation overflow.
19328 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19330 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19331 (x_session_initialize): Do not assume string length fits in int.
19333 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19334 This is unlikely, but can occur if DPI is outlandish.
19336 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19337 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19339 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
19340 * xrdb.c (magic_file_p, search_magic_path):
19341 Omit last arg SUFFIX; it was always 0. All callers changed.
19342 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
19344 * xfont.c (xfont_match): Avoid need for strlen.
19346 * xfns.c: Don't assume strlen fits in int.
19347 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
19349 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19350 not unsigned long, as we prefer signed integers. All callers changed.
19351 Detect integer overflow in repeat count.
19352 (message_dolog): Don't assume print length fits in 39 bytes.
19353 (display_mode_element): Don't assume strlen fits in int.
19355 * termcap.c: Don't assume sizes fit in int and never overflow.
19356 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
19357 (gobble_line): Check for size-calculation overflow.
19359 * minibuf.c (Fread_buffer):
19360 * lread.c (intern, intern_c_string):
19361 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

19365 * gtkutil.c (style_changed_cb): Avoid need for strlen.
19367 * font.c: Don't assume string length fits in int.
19368 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
19369 Use ptrdiff_t, not int.
19370 (font_intern_prop): Don't assume string length fits in int.
19371 Don't assume integer property fits in fixnum.
19372 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19374 * filelock.c: Fix some buffer overrun and integer overflow issues.
19375 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19376 Reformulate so as not to need the command string.
19377 Invoke gzip -cd rather than gunzip, as it's more portable.
19378 (lock_info_type, lock_file_1, lock_file):
19379 Don't assume pid_t and time_t fit in unsigned long.
19380 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19381 (current_lock_owner): Prefer signed type for sizes.
19382 Use memcpy, not strncpy, where memcpy is what is really wanted.
19383 Don't assume (via atoi) that time_t and pid_t fit in int.
19384 Check for time_t and/or pid_t out of range, e.g., via a network share.
19385 Don't alloca where an auto var works fine.
19387 * fileio.c: Fix some integer overflow issues.
19388 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19389 Don't assume string length fits in int.
19390 (directory_file_name): Don't assume string length fits in long.
19391 (make_temp_name): Don't assume pid fits in int, or that its print
19392 length is less than 20.
19394 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19396 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19398 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19400 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19401 We prefer signed integers, even for size calculations.
19403 * emacs.c: Don't assume string length fits in 'int'.
19404 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19405 (main): Don't invoke strlen when not needed.
19407 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

19411 (Fgetenv_internal):
19412 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19414 * lread.c (invalid_syntax): Omit length argument.
19415 All uses changed. This doesn't fix a bug, but it simplifies the
19416 code away from its former Hollerith-constant appearance, and it's
19417 one less 'int' to worry about when looking at integer-overflow issues.
19418 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19420 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19421 This didn't break anything, but it didn't help either.
19422 It's confusing to put a bogus integer in a place where the actual
19423 value does not matter.
19424 (LIST_END_P): Remove unused macro and its bogus comment.
19425 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19427 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19428 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19430 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19431 We prefer signed types, and the value cannot exceed the EMACS_INT
19432 range anyway (because otherwise the length would not be representable).
19433 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19434 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19435 This avoids a GCC warning when WIDE_EMACS_INT.
19437 * indent.c (sane_tab_width): New function.
19438 (current_column, scan_for_column, Findent_to, position_indentation)
19439 (compute_motion): Use it. This is just for clarity.
19440 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19442 * image.c (xbm_image_p): Don't assume stated width, height fit in int.

19445 * composite.c (composition_gstring_put_cache):
19446 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19448 * editfns.c, insdel.c:
19449 Omit unnecessary forward decls, to simplify future changes.
19451 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19453 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19455 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19456 Use much-faster test for byte-length change.
19457 Don't assume string byte-length fits in 'int'.
19458 Check that character arg fits in 'int'.
19459 (mapcar1): Declare byte as byte, for clarity.
19461 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19463 * fns.c (concat): Catch string overflow earlier.
19464 Do not rely on integer wraparound.
19466 * dispextern.h (struct it.overlay_strings_charpos)
19467 (struct it.selective): Now EMACS_INT, not int.
19468 * xdisp.c (forward_to_next_line_start)
19469 (back_to_previous_visible_line_start)
19470 (reseat_at_next_visible_line_start, next_element_from_buffer):
19471 Don't arbitrarily truncate the value of 'selective' to int.
19473 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19475 * composite.c: Don't truncate sizes to 'int'.
19476 (composition_gstring_p, composition_reseat_it)
19477 (composition_adjust_point): Use EMACS_INT, not int.
19478 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19479 not EMACS_UINT, for indexes.
19481 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19483 * buffer.c: Include <verify.h>.
19484 (struct sortvec.priority, struct sortstr.priority):
19485 Now EMACS_INT, not int.
19486 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19487 (struct sortstr.size, record_overlay_string)
19488 (struct sortstrlist.size, struct sortlist.used):
19489 Don't truncate size to int.
19490 (record_overlay_string): Check for size-calculation overflow.
19491 (init_buffer_once): Check at compile-time, not run-time.
19493 2011-06-22 Jim Meyering <meyering@redhat.com>
19495 Don't leak an XBM-image-sized buffer
19496 * image.c (xbm_load): Free the image buffer after using it.
19498 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19501 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19502 that Sun C diagnosed.
19503 * fns.c (secure_hash): Fix pointer signedness issue.
19504 * intervals.c (static_offset_intervals): New function.
19505 (offset_intervals): Use it.
19507 2011-06-21 Leo Liu <sdl.web@gmail.com>
19510 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19513 * fns.c (secure_hash): Rename from crypto_hash_function and change
19514 the first arg to accept symbols.
19515 (Fsecure_hash): New primitive.
19516 (syms_of_fns): New symbols.
19518 2011-06-20 Deniz Dogan <deniz@dogan.se>
19520 * process.c (Fset_process_buffer): Clarify return value in
19523 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19525 * dispnew.c (add_window_display_history): Use BVAR.
19527 * xdisp.c (debug_method_add): Use BVAR.
19528 (check_window_end, dump_glyph_matrix, dump_glyph)
19529 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19531 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19534 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19535 check till after the cache is created in init_frame_faces.
19537 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19539 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19541 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19543 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19544 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19545 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19547 Improve buffer-overflow checking (Bug#8873).
19548 * fileio.c (Finsert_file_contents):
19549 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19550 Remove the old (too-loose) buffer overflow checks.
19551 They weren't needed, since make_gap checks for buffer overflow.
19552 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19553 The old code merely checked for Emacs fixnum overflow, and relied
19554 on undefined (wraparound) behavior. The new code avoids undefined
19555 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19557 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19558 Tune. Don't use wider integers than needed. Don't use alloca.
19559 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19561 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19563 * insdel.c, lisp.h (buffer_overflow): New function.
19564 (insert_from_buffer_1, replace_range, replace_range_2):
19565 * insdel.c (make_gap_larger):
19566 * editfns.c (Finsert_char):
19567 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19569 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19571 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19573 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19575 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19576 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19578 * fileio.c: Don't assume EMACS_INT fits in off_t.
19579 (emacs_lseek): New static function.
19580 (Finsert_file_contents, Fwrite_region): Use it.
19581 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19583 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19585 * fns.c: Don't overflow int when computing a list length.
19586 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19587 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19588 truncation on 64-bit hosts. Check for QUIT every
19589 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19590 faster and is responsive enough.
19591 (Flength): Report an error instead of overflowing an integer.
19592 (Fsafe_length): Return a float if the value is not representable
19593 as a fixnum. This shouldn't happen except in contrived situations.
19594 (Fnthcdr, Fsort): Don't assume list length fits in int.
19595 (Fcopy_sequence): Don't assume vector length fits in int.
19597 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19598 (header_size, word_size): New constants.
19599 (allocate_vectorlike): Don't check size overflow here.
19600 (allocate_vector): Check it here instead, since this is the only
19601 caller of allocate_vectorlike that could cause overflow.
19602 Check that the new vector's length is representable as a fixnum.
19604 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19605 The previous code was bogus. For example, next_almost_prime (32)
19606 returned 39, which is undesirable as it is a multiple of 3; and
19607 next_almost_prime (24) returned 25, which is a multiple of 5 so
19608 why was the code bothering to check for multiples of 7?
19610 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19612 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19614 Variadic C functions now count arguments with ptrdiff_t.
19615 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19616 Back then I didn't know that the Emacs coding style prefers signed int.
19617 Also, in the meantime I found a few more instances where arguments
19618 were being counted with int, which may truncate counts on 64-bit
19619 machines, or EMACS_INT, which may be unnecessarily wide.
19620 * lisp.h (struct Lisp_Subr.function.aMANY)
19621 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19622 Arg counts are now ptrdiff_t, not size_t.
19623 All variadic functions and their callers changed accordingly.
19624 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19625 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19626 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19627 * callint.c (Fcall_interactively): Check arg count for overflow,
19628 to avoid potential buffer overrun. Use signed char, not 'int',
19629 for 'varies' array, so that we needn't bother to check its size
19630 calculation for overflow.
19631 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19632 * eval.c (apply_lambda):
19633 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19634 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19635 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19637 * callint.c (Fcall_interactively): Don't use index var as event count.
19639 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19640 * mem-limits.h (SIZE): Remove; no longer used.
19642 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19644 Remove unnecessary casts.
19645 * xterm.c (x_term_init):
19646 * xfns.c (x_set_border_pixel):
19647 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19648 These aren't needed now that we assume ANSI C.
19650 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19651 It's more likely to cause problems (due to unsigned overflow)
19654 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19656 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19658 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19660 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19662 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19664 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19666 GLYPH_CODE_FACE returns EMACS_INT, not int.
19667 * dispextern.h (merge_faces):
19668 * xfaces.c (merge_faces):
19669 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19670 Don't assume EMACS_INT fits in int.
19672 * character.h (CHAR_VALID_P): Remove unused parameter.
19673 * fontset.c, lisp.h, xdisp.c: All uses changed.
19675 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19677 * fns.c (concat): Minor tuning based on overflow analysis.
19678 This doesn't fix any bugs. Use int to hold character, instead
19679 of constantly refetching from Emacs object. Use XFASTINT, not
19680 XINT, for value known to be a character. Don't bother comparing
19681 a single byte to 0400, as it's always less.
19683 * floatfns.c (Fexpt):
19684 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19686 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19689 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19691 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19692 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19693 incorrectly succeed when S was a string, because 4294967386 was
19694 truncated before it was used.
19696 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19697 Otherwise, an out-of-range integer could cause undefined behavior
19700 * composite.c: Use int, not EMACS_INT, for characters.
19701 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19702 EMACS_INT, for values that are known to be in character range.
19703 This doesn't fix any bugs but is the usual style inside Emacs and
19704 may generate better code on 32-bit machines.
19706 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19707 This is for reasons similar to the recent CHAR_STRING fix.
19708 * charset.c (Fencode_char): Check that character arg is actually
19709 a character. Pass an int to ENCODE_CHAR.
19710 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19711 wider than 'int', as a compile-time check to prevent future regressions
19714 * character.c (char_string): Remove unnecessary casts.
19716 Make sure a 64-bit char is never passed to CHAR_STRING.
19717 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19718 by silently ignoring the top 32 bits, allowing some values
19719 that were far too large to be valid characters.
19720 * character.h: Include <verify.h>.
19721 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19722 arguments are no wider than unsigned, as a compile-time check
19723 to prevent future regressions in this area.
19725 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19726 (Fsubst_char_in_region):
19728 * xdisp.c (decode_mode_spec_coding):
19729 Adjust to CHAR_STRING's new requirement.
19730 * editfns.c (Finsert_char, Fsubst_char_in_region):
19731 * fns.c (concat): Check that character args are actually
19732 characters. Without this test, these functions did the wrong
19733 thing with wildly out-of-range values on 64-bit hosts.
19735 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19736 These casts should not be needed on 32-bit hosts, either.
19737 * keyboard.c (read_char):
19738 * lread.c (Fload): Remove casts to unsigned.
19740 * lisp.h (UNSIGNED_CMP): New macro.
19741 This fixes comparison bugs on 64-bit hosts.
19742 (ASCII_CHAR_P): Use it.
19743 * casefiddle.c (casify_object):
19744 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19745 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19746 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19747 * dispextern.h (FACE_FROM_ID):
19748 * keyboard.c (read_char): Use UNSIGNED_CMP.
19750 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19751 not to EMACS_INT, to avoid GCC warning.
19753 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19755 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19756 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19757 isn't needed on 32-bit machines.
19759 * buffer.c (Fgenerate_new_buffer_name):
19760 Use EMACS_INT for count, not int.
19761 (advance_to_char_boundary): Return EMACS_INT, not int.
19763 * data.c (Qcompiled_function): Now static.
19765 * window.c (window_body_lines): Now static.
19767 * image.c (gif_load): Rename local to avoid shadowing.
19769 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19770 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19771 * alloc.c (make_save_value): Integer argument is now of type
19772 ptrdiff_t, not int.
19773 (mark_object): Use ptrdiff_t, not int.
19774 * lisp.h (pD): New macro.
19775 * print.c (print_object): Use it.
19777 * alloc.c: Use EMACS_INT, not int, to count objects.
19778 (total_conses, total_markers, total_symbols, total_vector_size)
19779 (total_free_conses, total_free_markers, total_free_symbols)
19780 (total_free_floats, total_floats, total_free_intervals)
19781 (total_intervals, total_strings, total_free_strings):
19782 Now EMACS_INT, not int. All uses changed.
19783 (Fgarbage_collect): Compute overall total using a double, so that
19784 integer overflow is less likely to be a problem. Check for overflow
19785 when converting back to an integer.
19786 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19787 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19788 These were 'int' variables that could overflow on 64-bit hosts;
19789 they were never used, so remove them instead of repairing them.
19790 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19791 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19792 Previously, this ceilinged at INT_MAX, but that doesn't work on
19794 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19796 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19797 (allocate_vectorlike): Check for ptrdiff_t overflow.
19798 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19799 when a (possibly-narrower) signed value would do just as well.
19800 We prefer using signed arithmetic, to avoid comparison confusion.
19802 * alloc.c: Catch some string size overflows that we were missing.
19803 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19804 for convenience in STRING_BYTES_MAX.
19805 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19806 The definition here is exact; the one in lisp.h was approximate.
19807 (allocate_string_data): Check for string overflow. This catches
19808 some instances we weren't catching before. Also, it catches
19809 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19810 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19811 and ptrdiff_t and EMACS_INT are both 64 bits.
19813 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19814 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19815 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19817 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19819 * alloc.c (Fmake_string): Check for out-of-range init.
19821 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19823 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
19825 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
19827 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
19828 xg_get_default_scrollbar_width.
19830 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
19831 (int_gtk_range_get_value): Move to the scroll bar part of the file.
19832 (style_changed_cb): Call update_theme_scrollbar_width and call
19833 x_set_scroll_bar_default_width and xg_frame_set_char_size for
19834 all frames (Bug#8505).
19835 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
19836 Call gtk_window_set_resizable if HAVE_GTK3.
19837 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
19838 and height if HAVE_GTK3 (Bug#8505).
19839 (scroll_bar_width_for_theme): New variable.
19840 (update_theme_scrollbar_width): New function.
19841 (xg_get_default_scrollbar_width): Move code to
19842 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
19843 (xg_initialize): Call update_theme_scrollbar_width.
19845 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
19847 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
19849 2011-06-12 Martin Rudalics <rudalics@gmx.at>
19851 * frame.c (make_frame): Call other_buffer_safely instead of
19854 * window.c (temp_output_buffer_show): Call display_buffer with
19855 second argument Vtemp_buffer_show_specifiers and reset latter
19856 immediately after the call.
19857 (Vtemp_buffer_show_specifiers): New variable.
19858 (auto_window_vscroll_p, next_screen_context_lines)
19859 (Vscroll_preserve_screen_position): Remove leading asterisks from
19862 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
19864 Fix minor problems found by GCC 4.6.0 static checking.
19865 * buffer.c (Qclone_number): Remove for now, as it's unused.
19866 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
19867 (record_buffer): Remove unused local.
19868 * frame.c (other_visible_frames, frame_buffer_list): Now static.
19869 (set_frame_buffer_list): Remove; unused.
19870 * frame.h (other_visible_frames): Remove decl.
19871 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
19872 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
19873 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
19875 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
19876 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
19877 Define only if HAVE_GPM.
19878 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
19879 (update_hints_inhibit): Remove; never set. All uses removed.
19880 * widgetprv.h (emacsFrameClassRec): Remove decl.
19881 * window.c (delete_deletable_window): Now returns void, since it
19882 wasn't returning anything.
19883 (compare_window_configurations): Remove unused locals.
19884 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
19885 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
19886 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
19887 the same widths as pointers. This follows up on the 2011-05-06 patch.
19888 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
19889 * xterm.h: Likewise.
19890 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
19892 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
19894 * makefile.w32-in: Update dependencies.
19895 (LISP_H): Add lib/intprops.h.
19897 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
19899 * image.c (gif_load): Add animation frame delay to the metadata.
19900 (syms_of_image): Use DEFSYM. New symbol `delay'.
19902 2011-06-11 Martin Rudalics <rudalics@gmx.at>
19904 * window.c (delete_deletable_window): Re-add.
19905 (Fset_window_configuration): Rewrite to handle dead buffers and
19906 consequently deletable windows.
19907 (window_tree, Fwindow_tree): Remove. Supply functionality in
19909 (compare_window_configurations): Simplify code.
19911 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
19913 * image.c (imagemagick_load_image): Fix type mismatch.
19914 (Fimagemagick_types): Likewise.
19916 * window.h (replace_buffer_in_windows): Declare.
19918 2011-06-11 Martin Rudalics <rudalics@gmx.at>
19920 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
19921 Qclone_number. Remove external declaration of Qdelete_window.
19922 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
19924 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
19925 Run Qbuffer_list_update_hook if allowed.
19926 (Fother_buffer): Rewrite doc-string. Major rewrite for new
19927 buffer list implementation.
19928 (other_buffer_safely): New function.
19929 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
19930 calls to replace_buffer_in_windows and
19931 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
19933 (record_buffer): Inhibit quitting and rewrite using quittable
19934 functions. Run Qbuffer_list_update_hook if allowed.
19935 (Frecord_buffer, Funrecord_buffer): New functions.
19936 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
19937 Move switch-to-buffer to window.el.
19938 (bury-buffer): Move to window.el.
19939 (Vbuffer_list_update_hook): New variable.
19941 * lisp.h (other_buffer_safely): Add prototype in buffer.c
19944 * window.h (resize_frame_windows): Move up in code.
19945 (Fwindow_frame): Remove EXFUN.
19946 (replace_buffer_in_all_windows): Remove prototype.
19947 (replace_buffer_in_windows_safely): Add prototype.
19949 * window.c: Declare Qdelete_window static again. Move down
19950 declaration of select_count.
19951 (Fnext_window, Fprevious_window): Rewrite doc-strings.
19952 (Fother_window): Move to window.el.
19953 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
19954 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
19955 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
19957 (replace_buffer_in_windows): Implement by calling
19958 Qreplace_buffer_in_windows.
19959 (replace_buffer_in_all_windows): Remove with some functionality
19960 moved into replace_buffer_in_windows_safely.
19961 (replace_buffer_in_windows_safely): New function.
19962 (select_window_norecord, select_frame_norecord): Move in front
19963 of run_window_configuration_change_hook. Remove now obsolete
19965 (Fset_window_buffer): Rewrite doc-string.
19966 Call Qrecord_window_buffer.
19967 (keys_of_window): Move binding for other-window to window.el.
19969 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
19971 * dispextern.h (struct image): Replace data member, whose int_val
19972 and ptr_val fields were not used by anything, with a single
19975 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
19976 (gif_clear_image, gif_load, imagemagick_load_image)
19977 (gs_clear_image, gs_load): Callers changed.
19979 2011-06-10 Paul Eggert <eggert@cs.ucla.edu>
19981 * buffer.h: Include <time.h>, for time_t.
19982 Needed to build on FreeBSD 8.2. Problem reported by Herbert J. Skuhra.
19984 Fix minor problems found by static checking.
19986 * image.c (PixelGetMagickColor): Declare if ImageMagick headers don't.
19988 Make identifiers static if they are not used in other modules.

20428 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
20429 frame_window_p members of struct bidi_it.
20430 (compute_display_string_pos, compute_display_string_end):
20432 (push_it): Accept second argument POSITION, where pop_it should
20433 jump to continue iteration.
20434 (reseat_1): Initialize bidi_it.disp_pos.
20436 * keyboard.c (adjust_point_for_property): Adjust the call to
20437 display_prop_intangible_p to its new signature.

20447 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
20449 Malloc failure behavior now depends on size of allocation.
20450 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
20451 * lisp.h: Change signatures accordingly.
20452 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
20453 All callers changed. (Bug#8762)
20455 * gnutls.c: Use Emacs's memory allocators.
20456 Without this change, the gnutls library would invoke malloc etc.
20457 directly, which causes problems on non-SYNC_INPUT hosts, and which
20458 runs afoul of improving memory_full behavior. (Bug#8761)
20459 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20460 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20461 xfree instead of the default malloc, realloc, free.
20462 (Fgnutls_boot): No need to check for memory allocation failure,
20463 since xmalloc does that for us.
20465 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
20466 * category.c (hash_get_category_set):
20467 * ccl.c (ccl_driver):
20468 * charset.c (Fdefine_charset_internal):

20479 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
20480 (Fsxhash, Fgethash, Fputhash, Fmaphash):
20481 * image.c (make_image, search_image_cache, lookup_image)
20482 (xpm_put_color_table_h):
20483 * lisp.h (struct Lisp_Hash_Table):
20484 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
20485 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
20486 for hashes and hash indexes, instead of 'unsigned' and 'int'.
20487 * alloc.c (allocate_vectorlike):
20488 Check for overflow in vector size calculations.
20489 * ccl.c (ccl_driver):
20490 Check for overflow when converting EMACS_INT to int.
20491 * fns.c, image.c: Remove unnecessary static decls that would otherwise
20492 need to be updated by these changes.
20493 * fns.c (make_hash_table, maybe_resize_hash_table):
20494 Check for integer overflow with large hash tables.
20495 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20496 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20497 (SXHASH_REDUCE): New macro.
20498 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20499 Use it instead of discarding useful hash info with large hash values.
20500 (sxhash_float): New function.
20501 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20502 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20503 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20504 Rewrite to use FIXNUM_BITS, as this simplifies things.
20505 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20506 Adjust signatures to match updated version of code.
20507 (consing_since_gc): Now EMACS_INT, since a single hash table can
20508 use more than INT_MAX bytes.
20510 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
20512 Make it possible to build with GCC-4.6+ -O2 -flto.
20514 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
20516 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
20518 * minibuf.c (get_minibuffer, read_minibuf_unwind):
20519 Call minibuffer-inactive-mode.
20521 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
20523 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
20524 Update dependencies.
20526 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20528 * data.c (init_data): Remove code for UTS, this system is not
20531 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20533 Don't force ./temacs to start in terminal mode.
20535 * frame.c (make_initial_frame): Initialize faces in all cases, not
20536 only when CANNOT_DUMP is defined.
20537 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
20539 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20541 * dispnew.c (add_window_display_history): Use const for the string
20542 pointer. Remove declaration, not needed.
20544 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20546 Use 'inline', not 'INLINE'.
20547 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20548 * alloc.c, fontset.c (INLINE): Remove.
20549 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20550 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20551 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20552 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20553 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20555 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20557 Make it possible to run ./temacs.
20559 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20560 syms_of_callproc does the same thing. Remove test for
20561 "initialized", do it in the caller.
20562 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20564 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20566 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20567 (read_minibuf): Use get_minibuffer.
20568 (syms_of_minibuf): Use DEFSYM.
20569 (Qmetadata): New var.
20570 * data.c (Qbuffer): Don't make it static.
20571 (syms_of_data): Use DEFSYM.
20573 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20575 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20576 (CCL_CODE_MIN): New macro.
20578 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20580 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20582 * eval.c (Qdebug): Now static.
20583 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20584 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20585 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20587 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20589 * image.c: Various fixes to ImageMagick code comments.
20590 (Fimagemagick_types): Doc fix.
20592 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20594 Minor fixes prompted by GCC 4.6.0 warnings.
20596 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20598 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20599 (x_clipboard_manager_save_all): Move extern decl to ...
20600 * xterm.h: ... here, so that it can be checked for consistency.
20602 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20604 * xselect.c (x_clipboard_manager_save_frame)
20605 (x_clipboard_manager_save_all): New functions.
20606 (Fx_clipboard_manager_save): Lisp function deleted.
20608 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20609 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20611 * xterm.h: Update prototype.
20613 2011-05-28 William Xu <william.xwl@gmail.com>
20615 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20616 exiting (Bug#8239).
20618 2011-05-28 Jim Meyering <meyering@redhat.com>
20620 Avoid a sign-extension bug in crypto_hash_function.
20621 * fns.c (to_uchar): Define.
20622 (crypto_hash_function): Use it to convert some newly-signed
20623 variables to unsigned, to avoid sign-extension bugs. For example,
20624 without this change, (md5 "truc") would evaluate to
20625 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20626 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20627 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20629 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20631 Integer overflow fixes.
20633 * dbusbind.c: Serial number integer overflow fixes.
20634 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20635 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20636 to hold a serial number that is too large for a fixnum.
20637 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20638 Check for serial numbers out of range. Decode any serial number
20639 that was so large that it became a float. (Bug#8722)
20641 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20642 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20643 Use XFASTINT rather than XUINT when numbers are nonnegative.
20644 (xd_append_arg, Fdbus_method_return_internal):
20645 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20646 arguments, check that Lisp number is nonnegative, rather than
20647 silently wrapping negative numbers around. (Bug#8722)
20648 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20651 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20653 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20655 ccl: Add integer overflow checks.
20656 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20657 (IN_INT_RANGE): New macros.
20658 (ccl_driver): Use them to check for integer overflow when
20659 decoding a CCL program. Many of the new checks are whether XINT (x)
20660 fits in int; it doesn't always, on 64-bit hosts. The new version
20661 doesn't catch all possible integer overflows, but it's an
20662 improvement. (Bug#8719)
20664 * alloc.c (make_event_array): Use XINT, not XUINT.
20665 There's no need for unsigned here.
20667 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20668 This follows up to the 2011-05-06 change that substituted uintptr_t
20669 for EMACS_INT. This case wasn't caught back then.
20671 Rework Fformat to avoid integer overflow issues.
20672 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20673 now (part of C89). Include <verify.h>.
20674 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20675 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20676 (Fformat): Avoid the prepass trying to compute sizes; it was only
20677 approximate and thus did not catch overflow reliably. Instead, walk
20678 through the format just once, formatting and computing sizes as we go,
20679 checking for integer overflow at every step, and allocating a larger
20680 buffer as needed. Keep track separately whether the format is
20681 multibyte. Keep only the most-recently calculated precision, rather
20682 than them all. Record whether each argument has been converted to
20683 string. Use EMACS_INT, not int, for byte and char and arg counts.
20684 Support field widths and precisions larger than INT_MAX. Avoid
20685 sprintf's undefined behavior with conversion specifications such as %#d
20686 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20687 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20688 formatting out-of-range floating point numbers with int
20689 formats. (Bug#8668)
20691 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20693 * data.c: Avoid integer truncation in expressions involving floats.
20694 * data.c: Include <intprops.h>.
20695 (arith_driver): When there's an integer overflow in an expression
20696 involving floating point, convert the integers to floating point
20697 so that the resulting value does not suffer from catastrophic
20698 integer truncation. For example, on a 64-bit host (* 4
20699 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20700 Do not rely on undefined behavior after integer overflow.
20702 merge count_size_as_multibyte, parse_str_to_multibyte
20703 * character.c, character.h (count_size_as_multibyte):
20704 Rename from parse_str_to_multibyte; all uses changed.
20705 Check for integer overflow.
20706 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20707 since it's now a duplicate of the other. This is more of
20708 a character than a buffer op, so better that it's in character.c.
20709 * fns.c, print.c: Adjust to above changes.
20711 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20713 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20715 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20717 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20718 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20719 (x_clipboard_manager_save): Now static.
20720 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20722 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20723 (crypto_hash_function): Now static.
20724 Fix pointer signedness problems. Avoid unnecessary initializations.
20726 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20728 * termhooks.h (Vselection_alist): Make it terminal-local.
20730 * terminal.c (create_terminal): Initialize it.
20732 * xselect.c: Support for clipboard managers.
20733 (Vselection_alist): Move to termhooks.h as terminal-local var.
20734 (LOCAL_SELECTION): New macro.
20735 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20736 (symbol_to_x_atom): Remove gratuitous arg.
20737 (x_handle_selection_request, lisp_data_to_selection_data)
20738 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20739 (x_own_selection, x_get_local_selection, x_convert_selection):
20740 New arg, specifying work frame. Use terminal-local Vselection_alist.
20741 (some_frame_on_display): Delete unused function.
20742 (Fx_own_selection_internal, Fx_get_selection_internal)
20743 (Fx_disown_selection_internal, Fx_selection_owner_p)
20744 (Fx_selection_exists_p): New optional frame arg.
20745 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20746 (x_handle_selection_clear): Don't treat other terminals with the
20747 same keyboard specially. Use the terminal-local Vselection_alist.
20748 (x_clear_frame_selections): Use Frun_hook_with_args.
20750 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20752 * xterm.h: Add support for those atoms.
20754 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20756 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20757 (converted_selections, conversion_fail_tag): New global variables.
20758 (x_selection_request_lisp_error): Free the above.
20759 (x_get_local_selection): Remove unnecessary code.
20760 (x_reply_selection_request): Args changed; handle arbitrary array
20761 of converted selections stored in converted_selections.
20762 Separate the XChangeProperty and SelectionNotify steps.
20763 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20764 (x_convert_selection): New function.
20765 (x_handle_selection_event): Simplify.
20766 (x_get_foreign_selection): Don't ignore incoming requests while
20767 waiting for an answer; this will fail when we implement
20768 SAVE_TARGETS, and seems unnecessary anyway.
20769 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20770 (Vx_sent_selection_functions): Doc fix.
20772 2011-05-26 Leo Liu <sdl.web@gmail.com>
20774 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20776 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20778 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20780 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20781 for fringe update if it has periodic bitmap.
20782 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20783 and fringe_bitmap_periodic_p.
20785 * fringe.c (get_fringe_bitmap_data): New function.
20786 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20787 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20788 row. Mark glyph row for fringe update if periodicity changed.
20790 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20791 for fringe update unless it has periodic bitmap.
20793 2011-05-25 Kenichi Handa <handa@m17n.org>

20812 Remove macros that are defined and never used.
20813 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20815 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20817 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20818 (Fx_get_selection_internal): Minor cleanup.

20846 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20848 * systime.h (Time): Define only if emacs is defined.
20849 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20850 where the include path doesn't have X11/X.h by default. See
20851 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20853 2011-05-20 Kenichi Handa <handa@m17n.org>
20855 * composite.c (find_automatic_composition): Fix previous change.
20857 2011-05-20 Glenn Morris <rgm@gnu.org>

20862 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20864 2011-05-19 Glenn Morris <rgm@gnu.org>
20866 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20867 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20868 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20869 (lisp): Set the order to that of loadup.el.
20870 (shortlisp): Make it a copy of $lisp.
20871 (SOME_MACHINE_LISP): Remove.
20872 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20873 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20875 2011-05-18 Kenichi Handa <handa@m17n.org>
20877 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20878 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20879 (find_automatic_composition): Mostly rewrite for efficiency.
20881 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20883 * makefile.w32-in: Update dependencies.
20885 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20887 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20888 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20890 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20892 Fix some integer overflow issues, such as string length overflow.
20894 * insdel.c (count_size_as_multibyte): Check for string overflow.
20896 * character.c (lisp_string_width): Check for string overflow.
20897 Use EMACS_INT, not int, for string indexes and lengths; in
20898 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20899 the resulting string length overflows an EMACS_INT; instead,
20900 report a string overflow if no precision given. When checking for
20901 precision exhaustion, use a check that cannot possibly have
20902 integer overflow. (Bug#8675)
20903 * character.h (lisp_string_width): Adjust to new signature.
20905 * alloc.c (string_overflow): New function.
20906 (Fmake_string): Use it. This doesn't change behavior, but saves
20907 a few bytes and will simplify future changes.
20908 * character.c (string_escape_byte8): Likewise.
20909 * lisp.h (string_overflow): New decl.
20911 Fixups, following up to the user-interface timestamp change.
20912 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20913 for UI timestamps, instead of unsigned long.
20914 * msdos.c (mouse_get_pos): Likewise.
20915 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20916 * w32gui.h (Time): Define by including "systime.h" rather than by
20917 declaring it ourselves. (Bug#8664)
20919 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20920 * image.c (clear_image_cache): Likewise.
20922 * term.c (term_mouse_position): Don't assume time_t wraparound.
20924 Be more systematic about user-interface timestamps.
20925 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20926 and sometimes 'EMACS_UINT', to represent these timestamps.
20927 This change causes it to use 'Time' uniformly, as that's what X uses.
20928 This makes the code easier to follow, and makes it easier to catch
20929 integer overflow bugs such as Bug#8664.
20930 * frame.c (Fmouse_position, Fmouse_pixel_position):
20931 Use Time, not unsigned long, for user-interface timestamps.
20932 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20933 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20934 * keyboard.h (last_event_timestamp): Likewise.
20935 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20936 * menu.h (xmenu_show): Likewise.
20937 * term.c (term_mouse_position): Likewise.
20938 * termhooks.h (struct input_event.timestamp): Likewise.
20939 (struct terminal.mouse_position_hook): Likewise.
20940 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20941 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20942 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20943 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20944 what it was before.
20945 * menu.h, termhooks.h: Include "systime.h", for Time.
20947 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20948 Don't assume that the difference between two unsigned long values
20949 can fit into an integer. At this point, we know button_down_time
20950 <= event->timestamp, so the difference must be nonnegative, so
20951 there's no need to cast the result if double-click-time is
20952 nonnegative, as it should be; check that it's nonnegative, just in
20953 case. This bug is triggered when events are more than 2**31 ms
20954 apart (about 25 days). (Bug#8664)
20956 * xselect.c (last_event_timestamp): Remove duplicate decl.
20957 (x_own_selection): Remove needless cast to unsigned long.
20959 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20960 that always fit in int. Use a sentinel instead of a counter, to
20961 avoid a temp and to allay GCC's concerns about possible int overflow.
20962 * frame.h (struct frame): Use int for menu_bar_items_used
20963 instead of EMACS_INT, since it always fits in int.
20965 * menu.c (grow_menu_items): Check for int overflow.
20967 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20969 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20970 Before, the code was not consistent. These values cannot exceed
20971 2**31 - 1 so there's no need to make them unsigned.
20972 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20973 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20974 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20976 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20978 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20979 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20980 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20981 presumably because the widths might not match.
20983 * window.c (size_window): Avoid needless test at loop start.
20985 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20987 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20989 2011-05-12 Drew Adams <drew.adams@oracle.com>
20991 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20993 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20995 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20996 `width' to `bar_area_x' and `bar_area_width', respectively.
20997 (x_scroll_run): Take account of fringe background extension.
20999 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
21000 Rename local vars `left' and `width' to `bar_area_x' and
21001 `bar_area_width', respectively.
21002 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
21003 background extension.
21005 2011-05-10 Jim Meyering <meyering@redhat.com>
21007 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
21009 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
21011 * image.c (Finit_image_library): Return t for built-in image types,
21012 like pbm and xbm. (Bug#8640)
21014 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
21016 * w32menu.c (set_frame_menubar): Fix submenu allocation.
21018 2011-05-07 Eli Zaretskii <eliz@gnu.org>
21020 * w32console.c (Fset_screen_color): Doc fix.
21021 (Fget_screen_color): New function.
21022 (syms_of_ntterm): Defsubr it.
21024 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
21025 unlink the temporary file if Fcall_process didn't create it in the
21027 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
21028 child process will be redirected to a file specified with `:file'.
21029 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
21030 cue to call_process_cleanup not to close that handle.
21032 2011-05-07 Ben Key <bkey76@gmail.com>
21034 * makefile.w32-in: The bootstrap-temacs rule now makes use of
21035 one of two shell specific rules, either bootstrap-temacs-CMD or
21036 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
21037 to the previous implementation of the bootstrap-temacs rule.
21038 The bootstrap-temacs-CMD rule is similar to the previous
21039 implementation of the bootstrap-temacs rule except that it
21040 makes use of the ESC_CFLAGS variable instead of the CFLAGS
21043 These changes, along with some changes to nt/configure.bat,
21044 nt/gmake.defs, and nt/nmake.defs, are required to extend my
21045 earlier fix to add support for --cflags and --ldflags options
21046 that include quotes so that it works whether make uses cmd or
21049 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
21051 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
21052 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
21054 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
21055 a string. Handle both cases.
21056 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
21057 (Fdbus_register_method): Use Qinvalid_function.
21059 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21061 * makefile.w32-in: Update dependencies.
21062 (LISP_H): Add inttypes.h and stdin.h.
21063 (PROCESS_H): Add unistd.h.
21065 2011-05-06 Eli Zaretskii <eliz@gnu.org>
21067 * lread.c: Include limits.h (fixes the MS-Windows build broken by
21068 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
21070 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
21072 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
21074 * term.c (vfatal): Remove stray call to va_end.
21075 It's not needed and the C Standard doesn't allow it here anyway.
21077 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
21078 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
21080 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
21083 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
21085 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
21087 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
21089 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
21091 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
21093 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
21094 * charset.c (Fdefine_charset_internal): Don't initialize
21095 charset.code_space[15]. The value was garbage, on hosts with
21096 32-bit int (Bug#8600).
21098 * lread.c (read_integer): Be more consistent with string-to-number.
21099 Use string_to_number to do the actual conversion; this avoids
21100 rounding errors and fixes some other screwups. Without this fix,
21101 for example, #x1fffffffffffffff was misread as -2305843009213693952.
21102 (digit_to_number): Move earlier, for benefit of read_integer.
21103 Return -1 if the digit is out of range for the base, -2 if it is
21104 not a digit in any supported base. (Bug#8602)
21106 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
21108 * dispnew.c (scrolling_window): Return 1 if we scrolled,
21109 to match comment at start of function. This also removes a
21110 GCC warning about overflow in a 32+64-bit port.
21112 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
21114 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
21115 Reported by Stefan Monnier in
21116 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
21117 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21118 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
21120 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
21121 (EMACS_UINTPTR): Likewise, with uintptr_t.
21123 * lisp.h: Prefer 64-bit EMACS_INT if available.
21124 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
21125 on 32-bit hosts that have 64-bit int, so that they can access
21127 However, temporarily disable this change unless the temporary
21128 symbol WIDE_EMACS_INT is defined.
21130 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
21132 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
21133 This removes an assumption that EMACS_INT and long are the same
21134 width as pointers. The assumption is true for Emacs porting targets
21135 now, but we want to make other targets possible.
21136 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
21137 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
21138 In the rest of the code, change types of integers that hold casted
21139 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
21140 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
21141 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
21142 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
21143 No need to cast type when ORing.
21144 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
21145 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
21146 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
21147 assume EMACS_INT is the same width as char *.
21148 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
21149 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
21150 Remove no-longer-needed casts.
21151 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
21152 (xg_tool_bar_help_callback, xg_make_tool_item):
21153 Use EMACS_INTPTR to hold an integer
21154 that will be cast to void *; this can avoid a GCC warning
21155 if EMACS_INT is not the same width as void *.
21156 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
21157 * xdisp.c (display_echo_area_1, resize_mini_window_1):
21158 (current_message_1, set_message_1):
21159 Use a local to convert to proper width without a cast.
21160 * xmenu.c (dialog_selection_callback): Likewise.
21162 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
21163 Also, don't assume VALBITS / RAND_BITS is less than 5,
21164 and don't rely on undefined behavior when shifting a 1 left into
21166 * lisp.h (get_random): Change signature to match.
21168 * lread.c (hash_string): Use size_t, not int, for hash computation.
21169 Normally we prefer signed values; but hashing is special, because
21170 it's better to use unsigned division on hash table sizes so that
21171 the remainder is nonnegative. Also, size_t is the natural width
21172 for hashing into memory. The previous code used 'int', which doesn't
21173 retain enough info to hash well into very large tables.
21174 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
21176 * dbusbind.c: Don't possibly lose pointer info when converting.
21177 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21178 Use XPNTR rather than XHASH, so that the high-order bits of
21179 the pointer aren't lost when converting through void *.
21181 * eval.c (Fautoload): Don't double-shift a pointer.
21183 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
21185 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21187 * gnutls.c (DEF_GNUTLS_FN):
21188 * image.c (DEF_IMGLIB_FN): Make function pointers static.
21190 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
21192 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
21195 2011-05-05 Eli Zaretskii <eliz@gnu.org>
21197 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
21198 New version that can reserve upto 2GB of heap space.
21200 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
21202 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
21204 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
21206 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
21207 `gnutls_certificate_set_x509_key_file'.
21209 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
21211 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
21212 Update dependencies.
21214 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21216 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
21217 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
21218 Remove unused parameter `fildes'.
21219 * process.c (read_process_output, send_process): Don't pass it.
21221 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21223 Fix previous change: the library cache is defined in w32.c.
21224 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
21225 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
21227 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21229 Implement dynamic loading of GnuTLS on Windows.
21231 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
21232 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
21233 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21236 * gnutls.c (Qgnutls_dll): Define.
21237 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
21238 (gnutls_*): Declare function pointers.
21239 (init_gnutls_functions): New function to initialize function pointers.
21240 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
21241 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
21242 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21243 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
21244 (emacs_gnutls_write, emacs_gnutls_read)
21245 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
21246 (Fgnutls_available_p): New function.
21247 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
21248 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
21249 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
21251 * image.c: Include w32.h.
21252 (Vimage_type_cache): Delete.
21253 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
21254 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
21255 (w32_delayed_load): Move to w32.c.
21257 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
21259 * w32.c (QCloaded_from, Vlibrary_cache): Define.
21260 (w32_delayed_load): Move from image.c. When loading a library, record
21261 its filename in the :loaded-from property of the library id.
21262 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
21263 Initialize and staticpro them.
21264 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
21266 * process.c: Include lisp.h before w32.h, not after.
21267 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
21268 instead of gnutls_record_check_pending.
21270 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
21272 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
21274 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
21275 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
21278 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
21280 * xterm.c (x_set_frame_alpha): Do not set property on anything

21320 rather than `XVECTOR (FOO)->size'.
21322 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21323 inttypes.h, as a gnulib replacement is used if it not available in

21336 space for up to 2 characters produced in a loop.
21337 (decode_coding_iso_2022): Abort if there isn't enough place in
21338 charbuf for the composition carryover bytes.
21340 2011-04-21 Eli Zaretskii <eliz@gnu.org>

21345 %llo or %llx format is passed. (Bug#8545)
21347 * window.c (window_scroll_line_based): Use a marker instead of
21348 simple variables to record original value of point. (Bug#7952)

21351 produced by %s or %c overflows available buffer space. (Bug#8545)
21353 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21355 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21356 (SIZE_MAX): Move defn after all includes, as they might #define it.
21358 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21360 * w32.c (init_environment): Warn about defaulting HOME to C:\.

21364 * keyboard.c (Qdelayed_warnings_hook): Define.
21365 (command_loop_1): Run `delayed-warnings-hook'
21366 if Vdelayed_warnings_list is non-nil.
21367 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
21368 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
21370 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21372 * doprnt.c (doprnt): Don't return value smaller than the buffer
21373 size if the message was truncated. (Bug#8545).

21386 * makefile.w32-in: Update dependencies.
21388 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21390 Improve `doprnt' and its usage. (Bug#8545)
21391 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21392 `format_end'. Remove support for %l as a conversion specifier.
21393 Don't use xrealloc. Improve diagnostics when the %l size modifier
21394 is used. Update the commentary.
21396 * eval.c (verror): Simplify calculation of size_t.
21398 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21401 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21403 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21406 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21408 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21409 This makes this file independent of the recent pseudovector change.
21411 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21413 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21415 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21416 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21417 Remove unused local.
21418 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21420 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21421 GCC 4.6.0 optimizes based on type-based alias analysis.
21422 For example, if b is of type struct buffer * and v of type struct
21423 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21424 != &v->size, and therefore "v->size = 1; b->size = 2; return
21425 v->size;" must therefore return 1. This assumption is incorrect
21426 for Emacs, since it type-puns struct Lisp_Vector * with many other
21427 types. To fix this problem, this patch adds a new type struct
21428 vectorlike_header that documents the constraints on layout of vectors
21429 and pseudovectors, and helps optimizing compilers not get fooled
21430 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21431 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21432 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21434 (XSETPVECTYPE): Rewrite in terms of new macro.
21435 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21436 This is a bit clearer, and further avoids the possibility of
21437 undesirable aliasing.
21438 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21439 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21440 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21441 since Lisp_Subr is a special case (no "next" field).
21442 (ASIZE): Now uses header.size rather than size.
21443 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21444 to avoid the hassle of writing XVECTOR (foo)->header.size.
21445 (struct vectorlike_header): New type.
21446 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21447 object, to help avoid aliasing.
21448 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21449 (SUBRP): Likewise, since Lisp_Subr is a special case.
21450 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21451 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21452 (struct Lisp_Hash_Table): Combine first two members into a single
21453 struct vectorlike_header member. All uses of "size" and "next" members
21454 changed to be "header.size" and "header.next".
21455 * buffer.h (struct buffer): Likewise.
21456 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21457 * frame.h (struct frame): Likewise.
21458 * process.h (struct Lisp_Process): Likewise.
21459 * termhooks.h (struct terminal): Likewise.
21460 * window.c (struct save_window_data, struct saved_window): Likewise.
21461 * window.h (struct window): Likewise.
21462 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21463 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21464 * buffer.c (init_buffer_once): Likewise.
21465 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21467 * process.c (Fformat_network_address): Use local var for size,
21470 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21472 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21473 * data.c (atof): Remove decl; no longer used or needed.
21474 (digit_to_number): Move to lread.c.
21475 (Fstring_to_number): Use new string_to_number function, to be
21476 consistent with how the Lisp reader treats infinities and NaNs.
21477 Do not assume that floating-point numbers represent EMACS_INT
21478 without losing information; this is not true on most 64-bit hosts.
21479 Avoid double-rounding errors, by insisting on integers when
21480 parsing non-base-10 numbers, as the documentation specifies.
21481 * lisp.h (string_to_number): New decl, replacing ...
21482 (isfloat_string): Remove.
21483 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21484 (read1): Do not accept +. and -. as integers; this
21485 appears to have been a coding error. Similarly, do not accept
21486 strings like +-1e0 as floating point numbers. Do not report
21487 overflow for integer overflows unless the base is not 10 which
21488 means we have no simple and reliable way to continue.
21489 Break out the floating-point parsing into a new
21490 function string_to_number, so that Fstring_to_number parses
21491 floating point numbers consistently with the Lisp reader.
21492 (digit_to_number): Move here from data.c. Make it static inline.
21493 (E_CHAR, EXP_INT): Remove, replacing with ...
21494 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21495 (string_to_number): New function, replacing isfloat_string.
21496 This function checks for valid syntax and produces the resulting
21497 Lisp float number too. Rework it so that string-to-number
21498 no longer mishandles examples like "1.0e+". Use strtoumax,
21499 so that overflow for non-base-10 numbers is reported only when
21500 there's no portable and simple way to convert to floating point.
21502 * textprop.c (set_text_properties_1): Rewrite for clarity,
21503 and to avoid GCC warning about integer overflow.
21505 * intervals.h (struct interval): Use EMACS_INT for members
21506 where EMACS_UINT might cause problems. See
21507 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21508 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21509 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21511 (offset_intervals): Tell GCC not to worry about length overflow
21512 when negating a negative length.
21514 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21515 (overrun_check_free): Likewise.
21517 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21518 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21521 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21522 (gnutls_make_error): Rename local to avoid shadowing.
21523 (gnutls_emacs_global_deinit): ifdef out; not used.
21524 (Fgnutls_boot): Use const for pointer to readonly storage.
21525 Comment out unused local. Fix pointer signedness problems.
21527 * lread.c (openp): Don't stuff size_t into an 'int'.
21528 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21529 about possible signed overflow.
21531 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21532 (GDK_KEY_g): Don't define if already defined.
21533 (xg_prepare_tooltip): Avoid pointer signedness problem.
21534 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21536 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21537 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21539 * xfns.c (Fx_window_property): Simplify a bit,
21540 to make a bit faster and to avoid GCC 4.6.0 warning.
21541 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21543 * fns.c (internal_equal): Don't assume size_t fits in int.
21545 * alloc.c (compact_small_strings): Tighten assertion a little.
21547 Replace pEd with more-general pI, and fix some printf arg casts.
21548 * lisp.h (pI): New macro, generalizing old pEd macro to other
21549 conversion specifiers. For example, use "...%"pI"d..." rather
21550 than "...%"pEd"...".
21551 (pEd): Remove. All uses replaced with similar uses of pI.
21552 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21553 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21554 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21555 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21556 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21557 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21558 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21560 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21561 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21562 * print.c (safe_debug_print, print_object): Likewise.
21563 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21565 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21566 avoiding the 0 flag, which is not portable.
21567 * process.c (Fmake_network_process): Use pI to avoid cast.
21568 * region-cache.c (pp_cache): Likewise.
21569 * xdisp.c (decode_mode_spec): Likewise.
21570 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21571 behavior on 64-bit hosts with printf arg.
21572 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21573 (x_stop_queuing_selection_requests): Likewise.
21574 (x_get_window_property): Don't truncate byte count to an 'int'
21577 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21578 here, since it parses constructs like leading '-' and spaces,
21579 which are not wanted; and it overflows with large numbers.
21580 Instead, simply match F[0-9]+, which is what is wanted anyway.
21582 * alloc.c: Remove unportable assumptions about struct layout.
21583 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21584 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21585 (allocate_vectorlike, make_pure_vector): Use the new macros,
21586 plus offsetof, to remove unportable assumptions about struct layout.
21587 These assumptions hold on all porting targets that I know of, but
21588 they are not guaranteed, they're easy to remove, and removing them
21589 makes further changes easier.
21591 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21592 This doesn't fix a bug but makes the code clearer.
21593 (string_overrun_cookie): Now const. Use initializers that
21594 don't formally overflow signed char, to avoid warnings.
21595 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21596 can cause Emacs to crash when string overrun checking is enabled.
21597 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21598 multiple of sizeof (EMACS_INT); it need not be, if
21599 alignof(EMACS_INT) < sizeof (EMACS_INT).
21600 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21602 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
21604 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
21606 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
21608 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
21609 supposed to be handshaking. (Bug#8556)
21610 Reported by Paul Eggert <eggert@cs.ucla.edu>.

21614 * lisp.h (Qdebug): List symbol.
21615 * eval.c (Qdebug): Restore global linkage.
21616 * keyboard.c (debug-on-event): New variable.
21617 (handle_user_signal): Break into debugger when debug-on-event
21618 matches the current signal symbol.
21620 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
21622 * alloc.c (check_sblock, check_string_bytes)
21623 (check_string_free_list): Convert to standard C.
21625 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
21627 * w32.c (emacs_gnutls_push): Fix typo.
21629 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21631 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21632 "cast to pointer from integer of different size".
21634 Improve doprnt and its use in verror. (Bug#8545)
21635 * doprnt.c (doprnt): Document the set of format control sequences
21636 supported by the function. Use SAFE_ALLOCA instead of always
21639 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21640 is one byte too soon. Don't use xrealloc; instead xfree and
21643 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21645 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21648 * gnutls.c: Renamed global_initialized to
21649 gnutls_global_initialized. Added internals for the
21650 :verify-hostname-error, :verify-error, and :verify-flags
21651 parameters of `gnutls-boot' and documented those parameters in the
21652 docstring. Start callback support.
21653 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21654 unless a fatal error occurred. Call gnutls_alert_send_appropriate
21655 on error. Return error code.
21656 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
21657 (emacs_gnutls_read): Likewise.
21658 (Fgnutls_boot): Return handshake error code.
21659 (emacs_gnutls_handle_error): New function.
21660 (wsaerror_to_errno): Likewise.
21662 * w32.h (emacs_gnutls_pull): Add prototype.
21663 (emacs_gnutls_push): Likewise.
21665 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
21666 (emacs_gnutls_push): Likewise.
21668 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
21670 * process.c (wait_reading_process_output): Check if GnuTLS
21671 buffered some data internally if no FDs are set for TLS
21674 * makefile.w32-in (OBJ2): Add gnutls.$(O).
21675 (LIBS): Link to USER_LIBS.
21676 ($(BLD)/gnutls.$(0)): New target.

21680 * xdisp.c (handle_single_display_spec): Rename the
21681 display_replaced_before_p argument into display_replaced_p, to
21682 make it consistent with the commentary. Fix typos in the
21685 * textprop.c (syms_of_textprop): Remove dead code.

21691 to changes in oldXMenu/XMenu.h from 2011-04-16.
21692 <menu_help_message, prev_menu_help_message>: Constify.
21693 (IT_menu_make_room): menu->help_text is now `const char **';
21696 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
21697 to changes in oldXMenu/XMenu.h from 2011-04-16.
21698 (struct XMenu): Declare `help_text' `const char **'.

21709 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
21711 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
21714 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
21715 changes in globals.h immediately force recompilation.
21716 (TAGS): Depend on $(CURDIR)/m/intel386.h and

21960 ns_descriptor_to_entity that were caused by using free to
21961 deallocate memory blocks that were allocated by xmalloc (via

21982 (emacs_read, emacs_write): Use it.
21983 * process.c (send_process): Adjust to the new signatures of
21984 emacs_write and emacs_gnutls_write. Do not attempt to store

22185 since 0 is always ASCII.
22187 * fns.c (weak_hash_tables): Now static.
22189 * fileio.c: Make symbols static if they're not exported.
22190 (auto_saving, auto_save_mode_bits, auto_save_error_occurred):

22208 * editfns.c, lisp.h (get_operating_system_release): Remove.
22209 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
22210 worth the hassle of breaking this out.
22212 * xterm.c: Make symbols static if they're not exported.
22213 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

22316 * buffer.c (buffer_count): Remove unused var.

22325 * atimer.h (run_all_atimers): Remove; not exported.
22327 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
22328 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
22329 was inaccessible from Lisp.
22330 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
22331 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
22333 alloc.c: Import and export fewer symbols, and remove unused items.
22334 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
22336 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
22337 it's not optimized away by whole-program optimization.

22349 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
22350 (mark_backtrace): Define only if BYTE_MARK_STACK.
22351 * xdisp.c (message_enable_multibyte): Now static.
22353 Declare Lisp_Object Q* variables to be 'static' if not exported.
22354 This makes it easier for human readers (and static analyzers)
22355 to see whether these variables are used from other modules.
22356 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
22357 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

22366 Remove decls of unexported vars.
22367 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
22369 * lisp.h (DEFINE_FUNC): Make sname 'static'.
22371 Make Emacs functions such as Fatom 'static' by default.
22372 This makes it easier for human readers (and static analyzers)
22373 to see whether these functions can be called from other modules.
22374 DEFUN now defines a static function. To make the function external
22375 so that it can be used in other C modules, use the new macro DEFUE.
22376 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
22377 (Finit_image_library):
22378 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
22379 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
22380 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
22381 Remove decls, since these functions are now static.
22382 (Funintern, Fget_internal_run_time): New decls, since these functions
22383 were already external.
22385 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
22386 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

22392 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
22393 Mark functions with DEFUE instead of DEFUN,
22394 if they are used in other modules.
22395 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
22396 decls for now-static functions.
22397 * buffer.h (Fdelete_overlay): Remove decl.
22398 * callproc.c (Fgetenv_internal): Mark as internal.

22407 * image.c (Finit_image_library): New forward static decl.
22408 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
22409 * intervals.h (Fprevious_property_change):
22410 (Fremove_list_of_text_properties): Remove decls.
22411 * keyboard.c (Fthis_command_keys): Remove decl.
22412 (Fcommand_execute): New forward static decl.

22428 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
22430 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
22433 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22435 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22436 when at ZV. (Bug#8487)
22438 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22440 * charset.c (Fclear_charset_maps): Use xfree instead of free.
22442 * keyboard.c (parse_tool_bar_item): Likewise.
22443 * sound.c (sound_cleanup, alsa_close): Likewise.
22444 * termcap.c (tgetent): Likewise.
22445 * xfns.c (x_default_font_parameter): Likewise.
22446 * xsettings.c (read_and_apply_settings): Likewise.
22448 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22449 (overrun_check_free): Protoize.
22451 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22453 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22454 since callers should never pass a negative size.
22455 Change the signature to match that of plain 'read' and 'write'; see
22456 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22457 * lisp.h: Update prototypes of emacs_write and emacs_read.
22459 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22461 * xdisp.c (redisplay_window): Don't try to determine the character
22462 position of the scroll margin if the window start point w->startp
22463 is outside the buffer's accessible region. (Bug#8468)
22465 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22467 Fix write-region and its subroutines for buffers > 2GB.
22468 * fileio.c (a_write, e_write): Modify declaration of arguments and
22469 local variables to support buffers larger than 2GB.
22470 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22472 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22473 argument, local variables, and return value.
22475 * lisp.h: Update prototypes of emacs_write and emacs_read.
22477 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22479 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22481 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22483 Fix more problems found by GCC 4.6.0's static checks.
22485 * xdisp.c (vmessage): Use a better test for character truncation.
22487 * charset.c (load_charset_map): <, not <=, for optimization,
22488 and to avoid potential problems with integer overflow.
22489 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22490 * casetab.c (set_identity, shuffle): Likewise.
22491 * editfns.c (Fformat): Likewise.
22492 * syntax.c (skip_chars): Likewise.
22494 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22495 This also lets GCC 4.6.0 generate slightly better loop code.
22497 * callint.c (Fcall_interactively): <, not <=, for optimization.
22498 (Fcall_interactively): Count the number of arguments produced,
22499 not the number of arguments given. This is simpler and lets GCC
22500 4.6.0 generate slightly better code.
22502 * ftfont.c: Distingish more carefully between FcChar8 and char.
22503 The previous code passed unsigned char * to a functions like
22504 strlen and xstrcasecmp that expect char *, which does not
22505 conform to the C standard.
22506 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22507 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22508 char * when the C standard requires it.
22510 * keyboard.c (read_char): Remove unused var.
22512 * eval.c: Port to Windows vsnprintf (Bug#8435).
22513 Include <limits.h>.
22514 (SIZE_MAX): Define if the headers do not.
22515 (verror): Do not give up if vsnprintf returns a negative count.
22516 Instead, grow the buffer. This ports to Windows vsnprintf, which
22517 does not conform to C99. Problem reported by Eli Zaretskii.
22518 Also, simplify the allocation scheme, by avoiding the need for
22519 calling realloc, and removing the ALLOCATED variable.
22521 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22523 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22524 But keep the doprint source code for now, as we might revamp it
22525 and use it again (Bug#8435).
22526 * lisp.h (doprnt): Remove.
22527 * Makefile.in (base_obj): Remove doprnt.o.
22528 * deps.mk (doprnt.o): Remove.
22530 error: Print 32- and 64-bit integers portably (Bug#8435).
22531 Without this change, on typical 64-bit hosts error ("...%d...", N)
22532 was used to print both 32- and 64-bit integers N, which relied on
22533 undefined behavior.
22534 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22535 * lisp.h (error, verror): Mark as printf-like functions.
22536 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22537 Report overflow in size calculations when allocating printf buffer.
22538 Do not truncate output string at its first null byte.
22539 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22540 Truncate the output at a character boundary, since vsnprintf does not
22542 * charset.c (check_iso_charset_parameter): Convert internal
22543 character to string before calling 'error', since %c now has the
22545 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22546 overflow when computing char to be passed to 'error'. Do not
22547 pass Lisp_Object to 'error'; pass the integer instead.
22548 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22549 formatted with plain %d.
22551 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22553 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22555 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22557 * xterm.c (x_catch_errors): Remove duplicate declaration.
22559 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22561 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22563 2011-04-10 Jim Meyering <meyering@redhat.com>
22565 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22566 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22567 return ssize_t not "int", and use size_t as the buffer length.
22568 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22569 * gnutls.h: Update declarations.
22570 * process.c (read_process_output): Use ssize_t, to match.
22571 (send_process): Likewise.
22573 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22575 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22577 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22579 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22580 Use unsigned char, to match FcChar8 type definition.
22582 * xterm.c (handle_one_xevent):
22583 * xmenu.c (create_and_show_popup_menu):
22584 * xselect.c (x_decline_selection_request)
22585 (x_reply_selection_request): Avoid type-punned deref of X events.
22587 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22589 Fix some uses of `int' instead of EMACS_INT.
22590 * search.c (string_match_1, fast_string_match)
22591 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22592 (scan_buffer, find_next_newline_no_quit)

22594 (Fmatch_data): Make some `int' variables be EMACS_INT.
22596 * xdisp.c (display_count_lines): 3rd argument and return value now
22597 EMACS_INT. All callers changed.
22598 (pint2hrstr): Last argument is now EMACS_INT.

22640 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22642 * keyboard.c (read_char): Call Lisp function help-form-show,
22643 instead of using internal_with_output_to_temp_buffer.
22644 (Qhelp_form_show): New var.
22645 (syms_of_keyboard): Use DEFSYM macro.
22647 * print.c (internal_with_output_to_temp_buffer): Function deleted.

22660 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22662 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22664 Fix more problems found by GCC 4.6.0's static checks.
22666 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
22668 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22670 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22672 * xdisp.c (vmessage): Mark as a printf-like function.
22674 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

22681 to system-supplied API.
22683 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22685 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22686 This avoids several warnings with gcc -Wstrict-overflow.
22687 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22688 directly, rather than having caller test rule sign. This avoids
22689 some unnecessary tests.
22690 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22691 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22692 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22694 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22695 (xfont_open): Avoid unnecessary tests.
22697 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22699 * composite.h, composite.c (composition_gstring_put_cache):
22700 Use EMACS_INT, not int, for length.
22702 * composite.h (COMPOSITION_DECODE_REFS): New macro,
22703 breaking out part of COMPOSITION_DECODE_RULE.
22704 (COMPOSITION_DECODE_RULE): Use it.
22705 * composite.c (get_composition_id): Remove unused local vars,
22706 by using the new macro.
22708 * textprop.c (set_text_properties_1): Change while to do-while,
22709 since the condition is always true at first.
22711 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22712 (interval_deletion_adjustment): Return unsigned value.
22715 * process.c (list_processes_1, create_pty, read_process_output):
22716 (exec_sentinel): Remove vars that were set but not used.
22717 (create_pty): Remove unnecessary "volatile"s.
22718 (Fnetwork_interface_info): Avoid possibility of int overflow.
22719 (read_process_output): Do adaptive read buffering even if carryover.
22720 (read_process_output): Simplify nbytes computation if buffered.

22725 (update_syntax_table): Use unsigned instead of int.
22727 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
22728 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.

22731 * print.c (print_error_message): Avoid int overflow.
22733 * font.c (font_list_entities): Redo for clarity,
22734 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22736 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22737 (font_score): Avoid potential overflow in diff calculation.
22739 * fns.c (substring_both): Remove var that is set but not used.
22740 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22742 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22744 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22745 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22746 can always succeed if overflow has undefined behavior.
22748 * search.c (boyer_moore, wordify): Remove vars set but not used.
22749 (wordify): Omit three unnecessary tests.
22751 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22752 All callers changed. This avoids the need for an unused var.
22754 * casefiddle.c (casify_region): Remove var that is set but not used.
22756 * dired.c (file_name_completion): Remove var that is set but not used.
22758 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22760 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22761 (Finsert_file_contents): Remove unnecessary code checking fd.
22763 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22764 Check for integer overflow on size calculations.
22766 * buffer.c (Fprevious_overlay_change): Remove var that is set
22769 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22770 Remove vars that are set but not used.
22771 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22772 (timer_check_2): Mark vars as initialized.
22774 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22776 * image.c (lookup_image): Remove var that is set but not used.
22777 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22779 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22780 that are set but not used.
22782 * xfns.c (make_invisible_cursor): Don't return garbage
22783 if XCreateBitmapFromData fails (Bug#8410).
22785 * xselect.c (x_get_local_selection, x_handle_property_notify):
22786 Remove vars that are set but not used.
22788 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
22789 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
22791 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
22792 Remove var that is set but not used.
22793 (scroll_bar_windows_size): Now size_t, not int.
22794 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
22795 Check for overflow.
22797 * xfaces.c (realize_named_face): Remove vars that are set but not used.
22798 (map_tty_color) [!defined MSDOS]: Likewise.
22800 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22802 * coding.c: Remove vars that are set but not used.
22803 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22804 All callers changed.
22805 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22806 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22807 (decode_coding_charset): Remove vars that are set but not used.
22809 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22810 that is set but not used.
22812 * print.c (print_object): Remove var that is set but not used.
22814 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22815 The gnulib version avoids calling malloc in the usual case,
22816 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22817 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22818 * filelock.c (current_lock_owner): Likewise.
22819 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22820 * sysdep.c: Include allocator.h, careadlinkat.h.
22821 (emacs_no_realloc_allocator): New static constant.
22822 (emacs_readlink): New function.
22823 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22824 ../lib/careadlinkat.h.
22826 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22828 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22829 first non-nil return value).
22831 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
22833 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
22834 if not defined (Bug#8403).
22836 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22838 * xdisp.c (display_count_lines): Remove parameter `start',
22839 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22840 (get_char_face_and_encoding): Remove parameter `multibyte_p',
22841 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

22843 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22844 and thereabouts. All callers changed.
22845 (get_per_char_metric): Remove parameter `f', unused since
22846 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
22848 2011-04-02 Jim Meyering <meyering@redhat.com>
22850 do not dereference NULL upon failed strdup
22851 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22852 (ns_get_family): Likewise.
22854 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22856 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
22858 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
22860 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
22863 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
22865 Add lexical binding.
22867 * window.c (Ftemp_output_buffer_show): New fun.
22868 (Fsave_window_excursion):
22869 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
22871 * lread.c (lisp_file_lexically_bound_p): New function.
22872 (Fload): Bind Qlexical_binding.
22873 (readevalloop): Remove `evalfun' arg.
22874 Bind Qinternal_interpreter_environment.
22875 (Feval_buffer): Bind Qlexical_binding.
22876 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
22878 (syms_of_lread): Declare `lexical-binding'.
22880 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22882 * keyboard.c (eval_dyn): New fun.
22883 (menu_item_eval_property): Use it.
22885 * image.c (parse_image_spec): Use Ffunctionp.
22887 * fns.c (concat, mapcar1): Accept byte-code-functions.
22889 * eval.c (Fsetq): Handle lexical vars.
22890 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22891 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22892 (FletX, Flet): Obey lexical binding.
22893 (Fcommandp): Handle closures.
22894 (Feval): New `lexical' arg.
22895 (eval_sub): New function extracted from Feval. Use it almost
22896 everywhere where Feval was used. Look up vars in lexical env.
22898 (Ffunctionp): Move from subr.el.
22899 (Ffuncall): Handle closures.
22900 (apply_lambda): Remove `eval_flags'.
22901 (funcall_lambda): Handle closures and new byte-code-functions.
22902 (Fspecial_variable_p): New function.
22903 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22904 but without exporting it to Lisp.
22906 * doc.c (Fdocumentation, store_function_docstring):
22907 * data.c (Finteractive_form): Handle closures.
22909 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22912 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22914 (exec_byte_code): New function extracted from Fbyte_code to handle new
22915 calling convention for byte-code-functions. Add new byte-codes.
22917 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22919 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22921 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22923 * xdisp.c (redisplay_internal): Fix prototype.
22925 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22927 * xdisp.c (SCROLL_LIMIT): New macro.
22928 (try_scrolling): Use it when setting scroll_limit.
22929 Limit scrolling to 100 screen lines.
22930 (redisplay_window): Even when falling back on "recentering",
22931 position point in the window according to scroll-conservatively,
22932 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22934 (try_scrolling): When point is above the window, allow searching
22935 as far as scroll_max, or one screenful, to compute vertical
22936 distance from PT to the scroll margin position. This prevents
22937 try_scrolling from unnecessarily failing when
22938 scroll-conservatively is set to a value slightly larger than the
22939 window height. Clean up the case of PT below the margin at bottom
22940 of window: scroll_max can no longer be INT_MAX. When aggressive
22941 scrolling is in use, don't let point enter the opposite scroll
22942 margin as result of the scroll.
22943 (syms_of_xdisp) <scroll-conservatively>: Document the
22944 threshold of 100 lines for never-recentering scrolling.
22946 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22948 * dispextern.h (move_it_by_lines):
22949 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
22950 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
22951 (message_log_check_duplicate): Remove parameters `prev_bol' and
22952 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22953 (redisplay_internal): Remove parameter `preserve_echo_area',
22954 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22956 * indent.c (Fvertical_motion):
22957 * window.c (window_scroll_pixel_based, Frecenter):
22958 Don't pass `need_y_p' to `move_it_by_lines'.
22960 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22962 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22963 steal a few bits to be more compact.
22964 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22965 Remove unneeded casts.
22967 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22969 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22971 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22972 binding" message (bug#7967).
22974 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22976 Fix more problems found by GCC 4.6.0's static checks.
22978 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22979 Remove unused local var.
22981 * editfns.c (Fmessage_box): Remove unused local var.
22983 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22984 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22985 Omit unused local vars.
22986 * window.c (shrink_windows): Omit unused local var.
22987 * menu.c (digest_single_submenu): Omit unused local var.
22988 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22989 Omit unused local var.
22991 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22992 Don't assume string length fits in int.
22993 (keyremap_step, read_key_sequence): Use size_t for sizes.
22994 (read_key_sequence): Don't check last_real_key_start redundantly.
22996 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22997 instead of alloca (Bug#8344).
22999 * eval.c (Fbacktrace): Don't assume nargs fits in int.
23000 (Fbacktrace_frame): Don't assume nframes fits in int.
23002 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
23004 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
23007 * term.c (produce_glyphless_glyph): Remove unnecessary test.
23009 * cm.c (calccost): Turn while-do into do-while, for clarity.
23011 * keyboard.c (syms_of_keyboard): Use the same style as later
23012 in this function when indexing through an array. This also
23013 works around GCC bug 48267.
23015 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
23017 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
23019 * chartab.c (sub_char_table_ref_and_range): Redo for slight
23020 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
23022 * keyboard.c, keyboard.h (num_input_events): Now size_t.
23023 This avoids undefined behavior on integer overflow, and is a bit
23024 more convenient anyway since it is compared to a size_t variable.
23026 Variadic C functions now count arguments with size_t, not int.
23027 This avoids an unnecessary limitation on 64-bit machines, which
23028 caused (substring ...) to crash on large vectors (Bug#8344).
23029 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
23030 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
23031 All variadic functions and their callers changed accordingly.

23037 (funcall_lambda, mark_backtrace): Likewise.
23038 * fns.c (concat): Likewise.
23039 * frame.c (x_set_frame_parameters): Likewise.
23040 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
23041 0 if not found, not -1. All callers changed.
23043 * alloc.c (garbage_collect): Don't assume stack size fits in int.
23044 (stack_copy_size): Now size_t, not int.
23045 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
23047 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
23049 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
23050 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

23251 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
23253 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
23254 unconditionally since it does the check itself.
23256 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
23258 Fix more problems found by GCC 4.5.2's static checks.
23260 * coding.c (encode_coding_raw_text): Avoid unnecessary test
23261 the first time through the loop, since we know p0 < p1 then.
23262 This also avoids a gcc -Wstrict-overflow warning.
23264 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
23265 leading to a memory leak, possible in functions like
23266 load_charset_map_from_file that can allocate an unbounded number
23267 of objects (Bug#8318).
23269 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
23270 that could (at least in theory) be that large.
23272 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
23273 This is less likely to overflow, and avoids undefined behavior if
23274 overflow does occur. All callers changed. Use strtoul to scan
23275 for the unsigned long integer.
23276 (pint2hrstr): Simplify and tune code slightly.

23292 * process.c (Fmake_network_process): Use socklen_t, not int,
23293 where POSIX says socklen_t is required in portable programs.
23294 This fixes a porting bug on hosts like 64-bit HP-UX, where
23295 socklen_t is wider than int (Bug#8277).
23296 (Fmake_network_process, server_accept_connection):
23297 (wait_reading_process_output, read_process_output):
23300 * process.c: Rename or move locals to avoid shadowing.

23312 Include tparam.h instead, since it declares them.
23313 * cm.h (PC): Remove extern decl; tparam.h now does this.
23314 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23315 * terminfo.c: Include tparam.h, to check interfaces.
23316 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23317 (tparam): Adjust signature to match interface in tparam.h;
23318 this removes some undefined behavior. Check that outstring and len
23319 are zero, which they always are with Emacs.
23320 * tparam.h (PC, BC, UP): New extern decls.
23322 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
23323 (xftfont_open): Rename locals to avoid shadowing.

23341 (composition_update_it): Mark var as initialized.
23342 (find_automatic_composition): Mark vars as initialized,
23343 with a FIXME (Bug#8290).

23349 (BUF_DEC_POS): Be more systematic about renaming local temporaries
23350 to avoid shadowing.

23362 Fix pointer signedness.
23363 (alsa_choose_format): Remove unused local var.
23364 (wav_play): Initialize a variable to 0, to prevent undefined
23365 behavior (Bug#8278).
23367 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23369 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23371 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23372 clobbering (Bug#8298).
23373 * sysdep.c (sys_subshell): Likewise.
23374 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23376 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23377 This should get cleaned up, so that child_setup has the
23378 same signature on all platforms.
23380 * callproc.c (call_process_cleanup): Now static.
23381 (relocate_fd): Rename locals to avoid shadowing.
23383 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
23385 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
23386 not to be necessary, and produces flickering.
23388 2011-03-20 Glenn Morris <rgm@gnu.org>
23390 * config.in: Remove file.
23392 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

23437 Define only if needed.
23439 * unexelf.c (unexec): Name an expression,
23440 to avoid gcc -Wbad-function-cast warning.
23441 Use a different way to cause a compilation error if anyone uses
23442 n rather than nn, a way that does not involve shadowing.
23443 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
23445 * deps.mk (unexalpha.o): Remove; unused.

23502 * callint.c (quotify_arg, quotify_args): Now static.
23503 (Fcall_interactively): Rename locals to avoid shadowing.

23510 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
23511 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
23512 some of which prompt warnings from gcc -Wbad-function-cast.
23513 (Fformat_time_string, Fencode_time, Finsert_char):
23514 (Ftranslate_region_internal, Fformat):
23515 Rename or remove local vars to avoid shadowing.

23541 (GC_STRING_CHARS): Remove; not used.
23542 (Fmemory_limit): Cast sbrk's returned value to char *.
23544 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

23549 Use functions, not macros, for up- and down-casing (Bug#8254).
23550 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23551 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23552 to use the following functions instead of these macros.
23553 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23554 EMACS_INT, since callers assume the returned value fits in int.
23555 (upcase1): Likewise, for UPCASE_TABLE.
23556 (uppercasep, lowercasep, upcase): New static inline functions.
23557 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

23567 (regex_compile, re_match_2_internal): Mark locals as initialized.
23568 (RETALLOC_IF): Define only if needed.
23569 (WORDCHAR_P): Likewise. This one is never needed, but is used
23570 only in a comment talking about a compiler bug, so put inside
23571 the #if 0 of that comment.
23572 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23573 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

23599 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23600 New macros, so that the caller can use some names other than
23601 gcpro1, gcpro2, etc.
23602 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23604 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23605 argument, for consistency with GCPRO2_VAR, etc: it is now the
23606 prefix of the variable, not the variable itself. All uses
23608 * dired.c (directory_files_internal, file_name_completion):
23609 Rename locals to avoid shadowing.
23611 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23612 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23613 dired.c's scmp function, had undefined behavior.
23614 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23615 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23616 * buffer.h: ... to here, because these macros use current_buffer,
23617 and the new implementation with inline functions needs to have
23618 current_buffer in scope now, rather than later when the macros
23620 (downcase, upcase1): New static inline functions.
23621 (DOWNCASE, UPCASE1): Reimplement using these functions.
23622 This avoids undefined behavior in expressions like
23623 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23624 from race conditions in accessing the global variables
23625 case_temp1 and case_temp2.
23626 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23627 * lisp.h (case_temp1, case_temp2): Remove their decls.
23628 * character.h (ASCII_CHAR_P): Move from here ...
23629 * lisp.h: ... to here, so that the inline functions mentioned
23630 above can use them.

23634 * fileio.c (file_name_as_directory, directory_file_name):

23637 (file_name_as_directory): Use const pointers when appropriate.
23638 (Fexpand_file_name): Likewise. In particular, newdir might
23639 point at constant storage, so make it a const pointer.
23640 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
23641 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23643 (Fset_file_times, Finsert_file_contents, auto_save_error):

23648 to avoid shadowing.
23650 * marker.c (bytepos_to_charpos): Remove; unused.
23652 * lisp.h (verify_bytepos, count_markers): New decls,
23653 so that gcc does not warn that these functions aren't declared.
23655 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
23656 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
23657 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
23658 (copy_text): Remove unused local var.

23661 (lock_file_1): Rename local to avoid shadowing.
23663 * buffer.c (fix_overlays_before): Mark locals as initialized.
23664 (fix_start_end_in_overlays): Likewise. This function should be
23665 simplified by using pointers-to-pointers, but that's a different

23668 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
23669 (report_overlay_modification): Rename locals to avoid shadowing.

23672 Fix pointer signedness issue.
23673 (sys_subshell): Mark local as volatile if checking for lint,
23674 to suppress a gcc -Wclobbered warning that does not seem to be right.
23675 (MAXPATHLEN): Define only if needed.
23677 * process.c (serial_open, serial_configure): Move decls from here ...
23678 * systty.h: ... to here, so that they can be checked.
23680 * fns.c (get_random, seed_random): Move extern decls from here ...
23681 * lisp.h: ... to here, so that they can be checked.
23683 * sysdep.c (reset_io): Now static.

23844 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
