579 (cursor_row_p): Call row_for_charpos_p with 2nd argument PT.
580 (row_containing_pos): Call row_for_charpos_p instead of partially
581 doing the same. Fixes cursor positioning under longlines-mode

604 (entry_address, find_section, unexec): Use ptrdiff_t, not int,
605 when dealing with ElfW (Half) values, since they can exceed 2**31
606 on 64-bit OpenBSD hosts. Problem reported privately by Han Boetes.
607 (entry_address): Omit unused NUM arg. All uses changed.
609 2013-05-07 Juri Linkov <juri@jurta.org>

665 and dpyinfo->Xatom_net_current_desktop.
667 2013-05-06 Eli Zaretskii <eliz@gnu.org>
669 * xdisp.c (pos_visible_p): Use the special code for finding the
670 beginning of a display property or overlay for any "replacing"
671 display property, not just for display strings. This solves
672 incorrect reporting of position by posn-at-point. (Bug#14241)
674 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
676 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
677 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
678 Verify that ElfW (Half) fits in int.
679 (fatal): Use same signature as lisp.h.
680 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
681 configure and build with -DUNEXELF_DEBUG without worrying about
682 other modules that use DEBUG.
683 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
684 possibly-wide integers now uses it instead of plain fprintf.
685 (entry_address): New function, which avoids problems with 32-bit
686 overflow on 64-bit hosts.
687 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
688 (round_up): Don't assume the remainder fits in int.
689 (find_section): Use bool for boolean. Simplify debug code.
690 (unexec): Don't assume file sizes fit in int or size_t.
691 Omit unnecessary trailing newline in 'fatal' format.
692 Use strerror rather than outputting decimal error number.
693 Remove unused code when emacs is not defined;
694 this file relies on Emacs now.
695 Don't assume e_phnum and e_shnum are positive.
697 * regex.c: Fix problems when DEBUG is defined.
698 (extract_number, extract_number_and_incr): Define regardless of
699 whether DEBUG is defined; that's simpler and makes the code less
700 likely to go stale in the normal case when DEBUG is not defined.
701 Return int rather than taking an int * arg. All callers changed.
702 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
703 Remove, replacing with ...
704 (DEBUG_PRINT): New macro. All callers changed.
705 (DEBUG_COMPILES_ARGUMENTS): New macro.

710 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
711 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
712 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
713 Don't assume ptrdiff_t, size_t, and long are the same width as int.
714 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
715 This matters only when DEBUG is defined.
717 2013-05-05 Eli Zaretskii <eliz@gnu.org>
719 * xdisp.c (set_iterator_to_next): Set the
720 ignore_overlay_strings_at_pos_p flag only if we are _really_
721 iterating over an overlay string, as indicated by the
722 current.overlay_string_index member. (Bug#14306)
724 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
726 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
727 to where it is used, to avoid autorelease issues (Bug#14050).
729 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
731 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
732 * fileio.c (syms_of_fileio): Implement this.
733 * filelock.c (create_lock_file): If symbolic links don't work, so
734 we use a regular file as a lock file, do not fsync the lock file;
737 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
739 * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.

748 Use parentheses to disambiguate last part of the condition.
750 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
751 assertion violations. (Bug#14062)
753 2013-05-01 David Reitter <david.reitter@gmail.com>
755 * nsfns.m (ns_tooltip): Initialize.
757 2013-04-28 Eli Zaretskii <eliz@gnu.org>

760 a newline unless it's a CR character. (Bug#14287)
762 2013-04-28 Dan Nicolaescu <dann@gnu.org>
764 * dispextern.h (struct face): Move enum face_underline_type

776 * callint.c (Fcall_interactively): Call `Qread_number' for
777 interactive code letter `n' instead of using duplicate code.
780 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
782 * systime.h (make_timeval): Declare as 'const'.
784 2013-04-27 Kenichi Handa <handa@gnu.org>
786 * font.c (font_open_entity): Always open a font of manageable
789 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
791 Port better to AIX (Bug#14258).
792 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,

803 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
804 Without this fix, "make distclean" leaves stamp-h1 behind.
806 2013-04-20 Erik Charlebois <erikcharlebois@gmail.com>
808 * w32fns.c (w32_fullscreen_rect): New function to compute the
809 window rectangle for the given fullscreen mode.
810 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
811 longer tunes the window size. This keeps the window's edges flush
812 with the screen and allows the taskbar to hide itself in fullboth.
814 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
815 window decorations and uses the entire screen.
817 * w32term.h (w32_fullscreen_rect) Add prototype.

838 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
839 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
840 parentheses where appropriate.
842 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
844 * keyboard.c (timer_start_idle): Remove no-longer-used local.
846 2013-04-14 Eli Zaretskii <eliz@gnu.org>
848 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
849 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
850 Mention in the doc string that setting these variables takes
851 effect only after a call to set-window-buffer. (Bug#14200)
853 2013-04-13 Eli Zaretskii <eliz@gnu.org>
855 * indent.c (Fvertical_motion): Don't consider display strings on
856 overlay strings as display strings on the buffer position we
857 started from. This prevents vertical cursor motion from jumping
858 more than one line when there's an overlay string with a display
859 property at end of line.
860 Reported by Karl Chen <Karl.Chen@quarl.org> in
861 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

866 already selected (bug#14191).
868 2013-04-11 Eli Zaretskii <eliz@gnu.org>
870 * window.c (Fwindow_end): Test more flags, including the buffer's
871 last_overlay_modified flag, to determine whether the window's
872 display is really up-to-date. Prevents the function from
873 returning a stale value. (Bug#14170)
874 (Fwindow_line_height): Fix the test for up-to-date-ness of the
877 2013-04-10 Eli Zaretskii <eliz@gnu.org>
879 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
880 garbaged only if it is not already the top frame on its TTY.
881 This prevents flickering due to constant redrawing of TTY frames when
882 there are GUI frames open in the same session. (Bug#13864)
884 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
886 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
887 of marking the idle timers directly.

913 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
916 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
918 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
919 This bug was introduced by my 2013-02-25 change that simplified
920 data_start configuration. Without this change, on GNU/Linux
921 an Emacs configured with --enable-profiling fails immediately
922 due to a profiler signal.
923 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
924 with these flags. On platforms where special flags are needed

927 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
929 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>

937 * frame.h (decode_window_system_frame, window_system_available):
938 ...here, add new prototypes.

1001 Prefer < to > in range checks such as 0 <= i && i < N.
1002 This makes it easier to visualize quantities on a number line.
1003 This patch doesn't apply to all such range checks,
1004 only to the range checks affected by the 2013-03-24 change.
1005 This patch reverts most of the 2013-03-24 change.

1132 (redisplay_windows, redisplay_mode_lines, update_cursor_in_window_tree)
1133 (expose_window_tree): Likewise.
1134 Use contents slot, not buffer, where appropriate.
1135 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
1136 to avoid deleted windows. Use contents slot instead of buffer.

1439 2013-03-17 Ken Brown <kbrown@cornell.edu>
1441 * dispextern.h (RGB_PIXEL_COLOR): Move here from image.c. Use it
1442 as return type of image_background. (Bug#13981)
1443 * image.c (RGB_PIXEL_COLOR): Move to dispextern.h.

1453 * nsfns.m (ns_filename_from_panel, ns_directory_from_panel):
1455 (Fns_read_file_name): ret is BOOL. If ! dir_only_p, don't choose
1456 directories. If filename is nil, get directory name (Bug#13932).
1457 Use getFilename and getDirectory.
1458 (getFilename, getDirectory): New methods for EmacsSavePanel and
1460 (ok:): In EmacsOpenPanel, if we can't choose directories, just return.

1472 * coding.h (struct coding_system): New member eol_seen.
1474 * coding.c (detect_ascii): New function.
1475 (detect_coding): Set coding->head_ascii and coding->eol_seen only
1476 when the source bytes are actually scanned. On detecting for
1477 coding_category_utf_8_auto, call detect_ascii instead of scanning
1478 source bytes directly.
1479 (produce_chars): Call insert_from_gap with the new arg 0.
1480 (encode_coding): Likewise.
1481 (decode_coding_gap): Control ASCII optimization by the variable
1482 disable_ascii_optimization instead of #ifndef .. #endif.

1504 * w32term.c (w32_read_socket) <WM_WINDOWPOSCHANGED>: Remove old
1505 and incorrect code. Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE
1507 (w32fullscreen_hook): If the frame is visible, reset
1508 f->want_fullscreen flag after changing the frame size. If the
1509 frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
1512 2013-03-13 Daniel Colascione <dancol@dancol.org>
1514 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
1515 too so that these builds can use Cygwin's file conversion
1516 functions. (We've been building and linking cygw32.o all along
1517 and just not using it.)
1519 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
1521 File synchronization fixes (Bug#13944).
1522 * Makefile.in (LIB_FDATASYNC): New macro.

1525 * fileio.c (Fwrite_region, write_region_inhibit_fsync):
1526 Don't worry about HAVE_FSYNC, since a substitute fsync is
1527 available if the system lacks one.
1528 (Fwrite_regin): Retry fsync if interrupted.
1530 2013-03-13 Eli Zaretskii <eliz@gnu.org>
1532 * w32term.c (w32_read_socket): If the Emacs frame is being
1533 activated, call w32fullscreen_hook, to make sure the new frame
1534 dimensions are in effect. (Bug#13937)
1536 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
1538 * xdisp.c (init_iterator): Simplify because both character and byte
1539 positions are either specified or -1. Add eassert. Adjust comment.
1540 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
1541 character and byte positions can be obtained from marker.
1543 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>

1558 a function pointer type; the C Standard requires this.
1560 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
1561 Include <sys/param.h> unconditionally, as that works elsewhere and
1562 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
1563 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
1566 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>
1568 * insdel.c (adjust_after_replace): Use bool for boolean.

1592 call ShellExecute in cygw32 builds.
1594 * w32fn.c (Fx_file_dialog): Use the above macros to simplify the
1595 common file dialog code.
1597 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
1598 can just use du like other systems.
1600 * coding.c (from_unicode_buffer): Declare.
1601 * coding.c (from_unicode_buffer): Implement.
1603 2013-03-10 Stefan Monnier <monnier@iro.umontreal.ca>

1649 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
1650 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
1651 from Elisp via unread-command-events.
1653 * keyboard.c (access_keymap_keyremap): Accept nil return value from
1654 functions to mean "no change".
1656 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1658 region-cache.c, scroll.c, search.c: Use bool for booleans.
1659 * lisp.h (compile_pattern):

1664 (search_regs_saved, Fregexp_quote):
1665 Use bool for boolean.
1666 * region-cache.c (region_cache_forward, region_cache_backward):
1667 Fix comments to match code: these functions return int, not boolean.
1669 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1671 * search.c (find_newline): Accept start and end byte positions
1672 as arguments and allow -1 if not known.
1673 (find_newline_no_quit): Likewise for start position.
1674 * lisp.h (find_newline, find_newline_no_quit): Adjust prototype.
1675 * bidi.c (bidi_find_paragraph_start): Pass byte position to
1676 find_newline_no_quit, thus eliminating CHAR_TO_BYTE.
1677 * editfns.c (Fconstrain_to_field): Break long line.
1678 Adjust call to find_newline.
1679 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

1683 (get_visually_first_element, move_it_vertically_backward): Likewise.
1684 Obtain byte position from the display iterator, where appropriate.
1686 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1688 print.c, process.c: Use bool for booleans.
1689 * lisp.h (wait_reading_process_output):
1690 * print.c (print_output_debug_flag, PRINTDECLARE, printchar)
1691 (strout, debug_output_compilation_hack, float_to_string, print)
1693 * process.c (kbd_is_on_hold, inhibit_sentinels, process_output_skip)

1704 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1706 * bidi.c (bidi_fetch_char): Swap first and second arguments
1707 to match other functions accepting character and byte positions.
1709 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.
1710 (bidi_paragraph_init): Likewise. Use DEC_BOTH which is faster
1711 when you need just to move to the previous buffer position.
1712 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1714 2013-03-07 Eli Zaretskii <eliz@gnu.org>

1727 Adjust comments, style and calls to compute_motion.
1728 (Fvertical_motion): Adjust call to vmotion.
1729 * window.c (Fdelete_other_windows_internal): Record window start
1730 byte position and adjust call to vmotion.
1731 (window_scroll_line_based): Likewise with call to compute_motion.
1733 (Frecenter): Adjust calls to vmotion.
1735 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>
1737 * lisp.h (list2i, list3i): New functions.
1738 (list4i): Move from window.c and make LISP_INLINE.
1739 * editfns.c (make_lisp_time):

1751 2013-03-06 Eli Zaretskii <eliz@gnu.org>
1753 * search.c (find_newline_no_quit): Rename from find_next_newline.
1756 * lisp.h (find_newline_no_quit): Rename prototype.
1758 * xdisp.c (back_to_previous_line_start)

1760 (move_it_vertically_backward): Callers of find_newline_no_quit changed.
1761 * indent.c (vmotion): Callers of find_newline_no_quit changed.
1762 * bidi.c (bidi_find_paragraph_start): Callers of
1763 find_newline_no_quit changed.

1783 (decode_coding, encode_coding): Add USE_SAFE_ALLOCA and SAFE_FREE.
1784 (decode_coding_object): Simplify since xrealloc never returns NULL.
1787 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
1789 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1790 * sysdep.c (list_system_processes)
1791 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1792 Make it a stub in this case; otherwise the build might fail,
1793 and this code hasn't been tested on such hosts anyway.
1794 Problem reported by Nelson H. F. Beebe in
1795 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1796 and analyzed by Jérémie Courrèges-Anglas in
1797 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1799 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1801 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1802 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1803 (get_visually_first_element, move_it_vertically_backward): Ajust users.
1804 * bidi.c (bidi_find_paragraph_start): Likewise.
1805 * indent.c (vmotion): Likewise.
1807 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1809 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1810 * filelock.c: Include <c-ctype.h>.
1811 (MAX_LFINFO): New top-level constant.
1812 (lock_info_type): Remove members pid, boot_time. Add members at,
1813 dot, colon. Change user member to be the entire buffer, not a
1814 pointer. This allows us to handle the case where a foreign
1815 pid or boot time exceeds the local range. All uses changed.
1816 (LINKS_MIGHT_NOT_WORK): New constant.
1817 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1818 (defined_WINDOWSNT): Remove.
1819 (MAKE_LOCK_NAME, file_in_lock_file_name):
1820 Always use .#FILE (not .#-FILE) for the file lock,
1821 even if it is a regular file.
1822 (rename_lock_file): New function.
1823 (create_lock_file): Use it.
1824 (create_lock_file, read_lock_data):
1825 Prefer a symbolic link for the lock file, falling back on a
1826 regular file if symlinks don't work. Do not try to create
1827 symlinks on MS-Windows, due to security hassles. Stick with
1828 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1829 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1830 host may be using a Windowsish file system, and cannot use
1831 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1832 doesn't work. Don't fail merely because of a symlink-contents
1833 length limit in the current file system; fall back on regular
1834 files. Increase the symlink contents length limit to 8 KiB, this
1835 should be big enough for any real use and doesn't crunch the
1837 (create_lock_file, lock_file_1, read_lock_data):
1838 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1839 (lock_file_1): Return error number, not bool. All callers changed.
1840 (ELOOP): New macro, if not already defined.
1841 (read_lock_data): Return size of lock file contents, not Lisp object.
1842 All callers changed. Handle a race condition if some other process
1843 replaces a regular-file lock with a symlink lock or vice versa,
1844 while we're trying to read the lock.
1845 (current_lock_owner): Parse contents more carefully, to help avoid
1846 confusing a regular-file lock with some other application's use
1847 of the file. Check for lock file contents being too long, or
1848 not parsing correctly.
1849 (current_lock_owner, lock_file):
1850 Allow foreign pid and boot times that exceed the local range.
1851 (current_lock_owner, lock_if_free, lock_file):
1852 Simplify allocation of lock file contents.
1853 * w32.c (sys_rename_replace): New function, containing most of
1854 the contents of the old sys_rename.
1855 (sys_rename): Use it.
1856 (fchmod): New dummy function.
1857 * w32.h (sys_rename_replace, fchmod): New decls.
1859 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1861 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1862 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1863 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1864 <dmantipov@yandex.ru>.
1866 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1868 * composite.c (get_composition_id, fill_gstring_header):
1869 Use make_uninit_vector where appropriate.
1870 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1871 * xselect.c (clean_local_selection_data): Likewise.
1873 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1875 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1876 * image.c (imagemagick_load_image): Calculate height and width
1877 after flattening the image, not before.
1879 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1881 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1882 * ftfont.c (ftfont_shape_by_flt): Likewise.
1883 * w32uniscribe.c (uniscribe_shape): Likewise.
1885 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1887 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1888 The old approach, which fell back on DIR/.#FILE.0 through
1889 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1890 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1891 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1892 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1893 because the locking mechanism was never reliable in that case).
1894 This patch fixes this and other bugs discovered by a code
1895 inspection that was prompted by
1896 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1897 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1898 to avoid interoperability problems between the MS-Windows and
1899 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1900 instances of Emacs now ignore each others' locks.
1901 * filelock.c (defined_WINDOWSNT): New constant.
1902 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1903 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1904 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1905 regular files on MS-Windows hosts.
1906 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1907 Use SAFE_ALLOCA to avoid problems with long file names.
1908 (MAX_LFINFO): Now a local constant, not a global macro.
1909 (IS_LOCK_FILE): Remove.
1910 (lock_file_1): Don't inspect errno if symlink call succeeds;
1911 that's not portable.
1912 (lock_file): Document that this function can return if lock
1914 (lock_file): Don't access freed storage.
1916 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
1918 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
1920 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1922 * textprop.c: Use bool for booleans.
1923 (validate_interval_range, Fadd_text_properties)
1924 (Fremove_text_properties): Prefer bool to int when either works.
1926 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1928 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1929 If the interval tree changes as a side effect of calling
1930 modify_region, re-do processing starting from the call to
1931 validate_interval_range. (Bug#13743)
1933 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1935 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1938 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1940 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1941 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1942 access to the lock file until it is written and closed.
1945 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1947 * callint.c (Qcall_interactively):

1953 * window.c (Frecenter): Tiny docstring enhancement.
1955 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1957 Minor textprop integer cleanup.
1958 * intervals.h, textprop.c (add_text_properties_from_list):
1959 Return void, not int, since nobody uses the return value.
1960 * textprop.c (validate_plist, add_properties, remove_properties)
1961 (Fadd_text_properties):
1962 Don't assume list length fits in int.
1963 (interval_has_all_properties, interval_has_some_properties)
1964 (interval_has_some_properties_list, add_properties, remove_properties)
1965 (Fadd_text_properties, Fremove_text_properties)
1966 (Fremove_list_of_text_properties, text_property_stickiness):
1967 Use bool for booleans.
1968 (Fadd_text_properties, Fremove_text_properties):
1969 (Fremove_list_of_text_properties):
1970 Reindent do-while as per GNU style.

1974 Implement CLASH_DETECTION for MS-Windows.
1976 * filelock.c [WINDOWSNT]: Include w32.h.
1977 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1978 function of that name. Up-case the macro arguments.
1979 (IS_LOCK_FILE): New macro.
1980 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1981 (create_lock_file): New function, with body extracted from
1983 [WINDOWSNT]: Implement lock files by writing a regular file with
1984 the lock information as its contents.
1985 (read_lock_data): New function, on Posix platforms just calls
1987 [WINDOWSNT]: Read the lock info from the file.
1988 (current_lock_owner): Call read_lock_data instead of calling
1989 emacs_readlinkat directly.
1990 (lock_file) [WINDOWSNT]: Run the file name through
1993 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1994 just check if the process by that PID exists.
1996 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1997 also present, as doing so will fail to error out if the file
2000 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
2002 * textprop.c (Fadd_text_properties, Fremove_text_properties)
2003 (Fremove_list_of_text_properties): Skip all of the intervals in
2004 the region between START and END that already have resp. don't
2005 have the requested properties, not just the first one.
2006 Add assertions that the loop afterwards always modifies the
2007 properties. (Bug#13743)

2019 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
2020 (START_FILES): Remove. All uses removed.
2021 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
2022 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
2023 (buildobj.h): Use it.
2024 ($(ALLOBJS)): Depend on globals.h.
2025 (temacs$(EXEEXT)): Use $(ALLOBJS).
2026 * autodeps.mk (ALLOBJS): Move to Makefile.in.
2027 * deps.mk (vm-limit.o):
2028 * makefile.w32-in ($(BLD)/vm-limit.$(O)):

2036 (make_hdr): Use DATA_START instead of start_of_data.
2037 * vm-limit.c: Move most of mem-limits.h's contents here.
2038 (data_start): New decl. It's OK if this is approximate,
2039 so simplify-away some unnecessary exactness.
2040 (POINTER): Remove; all uses removed.
2041 (data_space_start): Now char *, to avoid casts.
2042 (exceeds_lisp_ptr): New function, replacing the old
2043 EXCEEDS_LISP_PTR macro. All uses changed.
2044 (check_memory_limits): Simplify and remove casts.
2045 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

2055 Fix regression introduced by July 10 filelock.c patch.
2056 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
2057 2012-07-10 patch to this file. Reported by Eli Zaretskii in
2058 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
2059 and diagnosed by Andreas Schwab in
2060 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
2062 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
2064 Assume C89 or better.
2065 * ralloc.c (SIZE, POINTER, NIL):
2066 * vm-limit.c (POINTER):
2067 Remove, replacing all uses with C89 equivalents. These old
2068 symbols were present only for porting to pre-C89 platforms.
2070 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
2072 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.

2088 2013-02-19 Daniel Colascione <dancol@dancol.org>
2090 * sheap.c (report_sheap_usage): Use message, not message1, so
2091 that we don't try to create a buffer while we're in the middle
2092 of dumping Emacs. Explain why.
2094 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
2096 * search.c (find_newline): Return byte position in bytepos.

2107 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
2109 2013-02-19 Eli Zaretskii <eliz@gnu.org>
2111 * w32proc.c (new_child): Avoid leaking handles if the subprocess
2112 resources were not orderly released.
2114 2013-02-17 Eli Zaretskii <eliz@gnu.org>
2116 * xdisp.c (x_draw_vertical_border): For a window that is neither
2117 the leftmost nor the rightmost, redraw both the left and the right
2118 vertical borders. (Bug#13723)

2140 * w32.c (sys_chown): Remove unused function.
2142 * w32term.c <input_signal_count>: Declare 'volatile'
2143 unconditionally. (Bug#9066)
2145 * w32.c (set_errno): Reset h_errno and don't set it to any other
2146 value. Set errno instead.
2147 (check_errno): Reset h_errno.
2148 (sys_socket, socket_to_fd, sys_bind, sys_connect)
2149 (sys_gethostname, sys_getservbyname, sys_getpeername)
2150 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
2151 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set

2159 2013-02-15 Eli Zaretskii <eliz@gnu.org>
2161 * keyboard.c (read_char): Fix calculation of auto-save time out
2162 when auto-save-timeout is less than 4. (Bug#13720)
2164 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
2165 time. Improve diagnostics in DebPrint. (Bug#13546)

2170 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
2171 make sure errno is set to an appropriate value. (Bug#13546)
2172 (socket_to_fd): Add assertion against indexing fd_info[] with a
2173 value that is out of bounds.
2174 (sys_accept): If fd is negative, do not set up the child_process
2175 structure for reading.
2177 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
2179 * composite.c (fill_gstring_header): Remove useless prototype.

2186 (get_overlay_arrow_glyph_row, display_mode_element):
2187 (decode_mode_spec_coding, message3):

2191 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
2193 Fix AIX port (Bug#13650).
2194 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
2195 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
2196 was #undeffed earlier, so it cannot be used as a macro here.
2197 Use the constant and not the macro.
2199 2013-02-15 Eli Zaretskii <eliz@gnu.org>
2201 * w32proc.c (new_child): If no vacant slots are found in
2202 child_procs[], make another pass looking for slots whose process
2203 has exited or died. (Bug#13546)
2205 * w32.c (sys_pipe): When failing due to file descriptors above
2206 MAXDESC, set errno to EMFILE.
2207 (_sys_read_ahead): Update cp->status when failing to read serial
2208 communications input, so that the status doesn't stay at
2209 STATUS_READ_IN_PROGRESS. (Bug#13546)
2211 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
2213 * gtkutil.c (tb_size_cb): New function.
2214 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
2216 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
2218 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
2221 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
2223 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
2225 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

2228 and break long line.
2229 * font.h (font_range): Adjust prototype.
2230 * composite.c (autocmp_chars): Pass byte position to font_range.
2231 Break long line. Remove useless prototype and format comment.
2233 2013-02-13 Glenn Morris <rgm@gnu.org>
2235 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
2237 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2239 Improve AIX port some more (Bug#13650).
2240 With this, it should be as good as it was in 23.3, though it's
2241 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
2242 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
2243 * unexaix.c (start_of_text): Remove.
2244 (_data, _text): Declare as char[], not int, as AIX manual suggests.
2245 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
2246 (orig_load_scnptr, orig_data_scnptr):
2247 Now off_t, not long, since they are file offsets.
2248 (make_hdr): Use _data, not start_of_data ().
2249 This is the key part of the fix.
2250 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
2251 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
2253 * pre-crt0.c (data_start): Initialize to 1.
2254 This ports to compilers that optimize the external declaration
2255 'int x = 0;' as if it were 'int x;' to shrink the executable.
2257 Improve AIX port (Bug#13650).
2258 This doesn't fix the bug, but it makes progress: Emacs builds now.
2259 * unexaix.c: Include inttypes.h, stdarg.h.
2260 (report_error, report_error_1): Mark as _Noreturn.
2261 (report_error): Don't report the wrong errno.
2262 (report_error_1): Now varargs. All callers changed.
2263 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
2264 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
2265 (write_ptr): Use %p to print address rather than %lx and a cast
2266 to unsigned long. Grow buffer a bit, to be safer.
2268 2013-02-13 Eli Zaretskii <eliz@gnu.org>
2270 * bidi.c (bidi_resolve_neutral): After finding the next
2271 non-neutral character, accept NEUTRAL_ON type as well, because
2272 directional control characters, such as LRE and RLE, have their
2273 type converted to that by bidi_resolve_weak. This avoids aborts
2274 when LRE/RLE follows a run of neutrals.
2275 (bidi_move_to_visually_next): Assert that return value of
2276 bidi_peek_at_next_level is non-negative. Negative values will
2279 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
2281 Minor getenv-related fixes.
2282 * callproc.c (Fcall_process_region) [!DOS_NT]:
2283 Avoid unnecessary duplicate call to getenv.
2284 * callproc.c (init_callproc):
2285 * dispnew.c (init_display):
2286 * sysdep.c (sys_subshell):
2287 Omit unnecessary cast of getenv or egetenv.
2289 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
2291 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
2292 Update dependencies.
2294 2013-02-12 Eli Zaretskii <eliz@gnu.org>
2296 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
2298 (display_line): Set w->region_showing to the value of
2299 it->region_beg_charpos, not to -1. This fixes redisplay
2300 optimization when cursor is moved up after M->. (Bug#13623)
2302 (try_scrolling): Scroll text up more if point is too close to ZV
2303 and inside the scroll margin. This makes sure point is moved
2304 outside the scroll margin in these cases.
2306 * window.h (struct window): region_showing can no longer be
2309 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
2311 Tune by using memchr and memrchr.
2312 * doc.c (Fsnarf_documentation):
2313 * fileio.c (Fsubstitute_in_file_name):
2314 * search.c (find_newline, scan_newline):
2315 * xdisp.c (pos_visible_p, display_count_lines):
2316 Use memchr and memrchr rather than scanning byte-by-byte.
2317 * search.c (find_newline): Rename from scan_buffer.
2318 Omit first arg TARGET, as it's always '\n'. All callers changed.
2320 Clean up read_key_sequence a tiny bit more.
2321 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
2322 (read_key_sequence): Remove unused locals.
2324 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
2326 Clean up read_key_sequence a bit; reread active keymaps after first event.
2327 * keyboard.c (read_char, read_char_x_menu_prompt)
2328 (read_char_minibuf_menu_prompt):
2329 Replace nmaps+maps with a single `map' arg.
2330 (follow_key): Operate on a single map.
2331 (active_maps): New function.
2332 (test_undefined): Also return true for nil bindings.
2333 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
2334 a single (composed) keymap. Remember `first_event' to choose the right
2335 set of active keymaps. Recompute the set of keymaps after receiving
2336 the first event. Remove GOBBLE_FIRST_EVENT.

2347 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
2349 * marker.c (set_marker_internal): If desired position is passed

2358 2013-02-10 Eli Zaretskii <eliz@gnu.org>
2360 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
2361 When text lines are longer than window's screen lines, don't move back
2362 too far. This speeds up some redisplay operations. (Bug#13675)
2364 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
2366 * syntax.c (scan_sexps_forward): Fix byte position calculation

2378 (sxhash_float): Return EMACS_UINT, for consistency with the other
2380 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
2381 non-static inline function and therefore can't use static vars.
2382 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
2383 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
2384 with the other hash functions.
2386 2013-02-09 Eli Zaretskii <eliz@gnu.org>
2388 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
2389 XXXXXX part of the temporary file pattern is not downcased even
2390 when w32-downcase-file-names is non-nil. (Bug#13661)
2392 * xdisp.c (decode_mode_spec): Remove handling of %t.
2394 * msdos.c (careadlinkatcwd): Remove.
2396 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
2398 * lread.c (skip_dyn_bytes): New function (bug#12598).

2434 argument is known to be a vector.
2435 * fns.c (Flocale_info): Likewise for ASET.
2436 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
2437 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
2439 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
2441 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar

2452 if isFullscreen returns YES.
2453 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
2454 (check_native_fs): New function.
2455 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.

2471 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
2472 (syms_of_nsterm): Add ns-use-native-fullscreen.
2474 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
2476 * fileio.c (Qchoose_write_coding_system): Now static.
2478 2013-02-04 Eli Zaretskii <eliz@gnu.org>
2480 * xdisp.c (window_buffer_changed): region_showing can be negative,
2481 which still means region is being displayed.
2482 (redisplay_internal): Resurrect code that forced redisplay of the
2483 whole window when showing region and the mark has changed.
2484 Record the new mark position to allow redisplay optimizations.
2485 (display_line): If it->region_beg_charpos is non-zero, set the
2486 window's region_showing member to -1. (Bug#13623) (Bug#13626)
2488 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
2489 not bitfield of 1 bit.
2491 2013-02-03 Daniel Colascione <dancol@dancol.org>
2493 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
2494 daemon mode works on cygw32 when Emacs is installed and not just
2497 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
2499 Avoid file time stamp bug on MS-Windows (Bug#13149).
2500 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
2501 as FAT32 doesn't update time stamps when truncating them.
2502 Also, check that a file time stamp is not a multiple of 100 ns;
2503 this should catch all instances of the problem on MS-Windows,
2504 as its native file system resolution is 100 ns or worse, and
2505 checking for a non-multiple of 100 ns should impose only a small
2506 overhead on systems with ns resolution.
2508 2013-02-02 Eli Zaretskii <eliz@gnu.org>
2510 Avoid encoding file names on MS-Windows when they need to be run
2511 through dostounix_filename.
2512 * w32.c (normalize_filename): Accept an additional argument
2513 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
2514 downcase it even if w32-downcase-file-names is non-nil.
2515 (dostounix_filename): Accept an additional argument MULTIBYTE and
2516 pass it to normalize_filename.
2517 (emacs_root_dir): Adjust.
2519 * msdos.h (dostounix_filename): Adjust prototype.
2521 * w32.h (dostounix_filename): Adjust prototype.
2523 * msdos.c (dostounix_filename): Accept an additional argument and
2525 (init_environment): Adjust callers of dostounix_filename.
2527 * fileio.c (Ffile_name_directory, file_name_as_directory)
2528 (directory_file_name, Fexpand_file_name)
2529 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
2531 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
2533 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
2534 variables, as egetenv is case-insensitive for DOS_NT.
2536 * dired.c (file_name_completion): Don't call Fdirectory_file_name
2537 with an encoded file name.
2539 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
2540 Adjust calls to dostounix_filename.
2542 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
2544 * unexw32.c (unexec): Adjust call to dostounix_filename.
2546 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
2548 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
2551 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
2554 * callproc.c (Fcall_process): Make sure program name in PATH and
2555 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
2556 is passed to exec/spawnve, which fails unless the file-name
2559 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
2560 even if w32-quote-process-args is nil.
2562 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2564 Fix timestamp bug when write-region appends nothing (Bug#13149).
2565 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
2566 the file's time stamp doesn't change if Emacs happens to write nothing
2567 to the file, and on a buggy file system this could cause Emacs to
2568 incorrectly infer that the file system doesn't have the bug.
2569 Avoid this problem by inhibiting the inference in this case.
2571 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
2573 * window.h (struct window): Convert base_line_number, base_line_pos
2574 and column_number_displayed members from Lisp_Object to ptrdiff_t.

2584 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
2585 (try_scrolling, try_cursor_movement, redisplay_window)
2586 (try_window_reusing_current_matrix, try_window_id, display_line)
2587 (display_mode_lines, decode_mode_spec): Adjust users.
2588 * .gdbinit (pwinx): Do not print sequence_number.
2590 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2592 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
2593 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
2594 * dired.c: Include <fcntl.h>.
2595 (open_directory): New function, which uses open and fdopendir
2596 rather than opendir. DOS_NT platforms still use opendir, though.

2599 (directory_files_internal, Ffile_attributes): Use it.
2600 (file_attributes, file_name_completion_stat): First arg is now fd,
2601 not dir name. All uses changed. Use fstatat rather than lstat +
2603 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
2604 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
2605 (emacs_readlinkat): New function, with much of the old
2606 Ffile_symlink_p, but with an fd argument for speed.
2607 It uses readlinkat rather than careadlinkatcwd, so that it
2608 need not assume the working directory.
2609 (Ffile_symlink_p): Use it.
2610 * filelock.c (current_lock_owner): Use emacs_readlinkat
2611 rather than emacs_readlink.
2612 * lisp.h (emacs_readlinkat): New decl.
2613 (READLINK_BUFSIZE, emacs_readlink): Remove.
2614 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2615 (emacs_norealloc_allocator, emacs_readlink): Remove.
2616 This stuff is moved to fileio.c.
2617 * w32.c (fstatat, readlinkat): New functions.
2618 (careadlinkat): Don't check that fd == AT_FDCWD.

2630 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2631 (sys_close): Zero out the flags for the file descriptor before
2632 closing it. (Bug#13546)
2634 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2635 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2636 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2639 * w32.c (w32_get_long_filename, init_environment, readlink):
2640 Support file names encoded in DBCS codepages.
2641 (readlink): Use the current file-name-coding-system, not the ANSI
2642 codepage, to decode and handle targets of symlinks.
2644 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2646 * w32.c (opendir): Now accepts a 'const char *'.
2648 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>

2660 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2662 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>

2665 debugging code. Adjust comment style here and there.
2666 * insdel.c (insert_1): Remove.
2667 * lisp.h (insert_1): Remove prototype.
2668 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2670 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2672 * w32.c (max_filename_mbslen): New function.
2673 (normalize_filename, readdir): Use it to detect locales where ANSI
2674 encoding of file names uses a double-byte character set (DBCS).
2675 If a DBCS encoding is used, advance by characters using
2676 CharNextExA, instead of incrementing a 'char *' pointer.
2677 Use _mbslwr instead of _strlwr. (Bug#13515)
2679 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial

2696 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2697 * frame.h (struct frame): Remove async_visible and async_iconified
2698 members, convert garbaged to unsigned bitfield. Adjust comments.

2718 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2720 * xdisp.c (message2, message2_nolog): Remove functions.
2721 (message3, message3_nolog): Extract nbytes and multibyteness directly
2722 from the string. Change all callers.
2723 (message3_nolog): Don't set message_enable_multibyte since set_message
2724 will reset it anyway.
2725 (message1, message1_nolog): Use message3.
2726 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2727 (with_echo_area_buffer): Remove last two arguments. Update all callers.

2742 * editfns.c (message_text, message_length): Remove vars.
2743 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2744 * fileio.c (auto_save_error): Use message3 instead of message2.

2784 * emacs.c (Qkill_emacs_hook): Now static.
2786 * fileio.c (Finsert_file_contents): Simplify.
2787 Remove unnecessary assignments and tests.
2789 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2791 * w32.c (acl_set_file): Don't test for errors unless
2792 set_file_security returns FALSE. Avoids spurious errors when
2795 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2797 * fileio.c (Finsert_file_contents): Revert code introduced at
2798 2013-01-18 in favor of the simpler and generally better fix.
2799 Save stack space by removing 'buffer' and reusing 'read_buf'
2802 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2804 * lisp.h (eabs): Define unconditionally (Bug#13419).
2805 The old "#if !defined (eabs)" was an unnecessary revenant of back
2806 when this macro was called "abs". Document 'eabs' better.
2808 2013-01-19 Glenn Morris <rgm@gnu.org>
2810 * fns.c (Frandom): Doc fix.
2812 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2814 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2815 segfault when there are lots of overlays.
2817 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2818 when there are lots of overlays.
2819 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2820 for the details and a way to reproduce.
2822 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2824 * fileio.c: Use O_APPEND to append.
2825 This corresponds better to the natural interpretation of "append",
2826 and avoids the need to open the output file twice, or to invoke
2827 lseek when APPEND is neither nil nor a number.
2828 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2829 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2830 file possibly twice, and lseeking to its end; this avoids the
2831 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2832 at the same time: the combination is never needed and apparently
2833 it doesn't work with DOS_NT.
2835 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2836 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2838 Allow floating-point file offsets.
2839 Problem reported by Vitalie Spinu in
2840 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2841 * fileio.c (emacs_lseek): Remove.
2842 (file_offset): New function.
2843 (Finsert_file_contents, Fwrite_region): Use it.
2845 2013-01-19 Chong Yidong <cyd@gnu.org>
2847 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2848 aborting on Fsignal (Bug#13289).
2850 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2852 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2853 set_file_security as failure due to insufficient privileges.
2854 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2855 (fstat): Return owner and group like 'stat' and 'lstat' do.
2857 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2859 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2860 The bug was observed on Ubuntu operating inside a virtual machine,
2861 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2862 The workaround introduces a race condition on non-buggy hosts,
2863 but it's an unlikely race and anyway there's a nearly identical
2864 nearby race that can't be fixed.
2865 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2867 (Fwrite_region): Test for file system time stamp bug.
2868 (init_fileio): New function.
2869 * lisp.h (init_fileio): Declare it.
2870 * emacs.c (main): Call it.
2872 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2873 and make it more consistent with other stat-failure diagnostics.
2875 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2877 Fix crash when inserting data from non-regular files.
2878 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2879 for the error description produced by valgrind.
2880 * fileio.c (read_non_regular): Rename to read_contents.
2881 Free Lisp_Save_Value object used to pass parameters.
2882 (read_non_regular_quit): Rename to read_contents_quit.
2883 (Finsert_file_contents): Redesign internal file reading loop to adjust
2884 gap and end positions after each read and so help make_gap to work
2885 properly. Do not signal an I/O error too early and so do not leave
2886 not yet decoded characters in a buffer, which was the reason of
2887 redisplay crash. Use list2 to build return value. Adjust comments.
2889 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2891 Close a race when statting and reading files (Bug#13149).
2892 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2893 This avoids a race if the file is renamed between stat and open.
2894 This race is not the problem originally noted in Bug#13149;
2895 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2897 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

2905 * alloc.c (format_save_value): Rename to make_save_value.
2906 (make_save_pointer): New function.
2907 (record_xmalloc): Use make_save_pointer.
2908 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2909 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2910 Change users of make_save_value to make_save_pointer.

2926 * keymap.c (map_keymap_internal): Use format_save_value.
2927 (map_keymap_char_table_item): Adjust accordingly.
2928 * fileio.c (non_regular_fd, non_regular_inserted)
2929 (non_regular_nbytes): Remove.
2930 (Finsert_file_contents): Convert trytry to ptrdiff_t.
2931 Use format_save_value to pass parameters to read_non_regular.
2932 (read_non_regular): Use XSAVE_ macros to extract parameters.
2934 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
2936 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
2938 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2940 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2941 extraction from any Lisp_Save_Value slot. Add type checking.
2942 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
2943 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
2944 * xselect.c: All users changed.
2946 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

2957 (save_excursion_restore): Use XSAVE_OBJECT.
2959 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
2961 Avoid needless casts with XSAVE_POINTER.
2962 * alloc.c (mark_object) [GC_MARK_STACK]:
2963 * dired.c (directory_files_internal_unwind):
2964 * fileio.c (do_auto_save_unwind):
2965 * gtkutil.c (pop_down_dialog):
2966 * keymap.c (map_keymap_char_table_item):
2967 * lread.c (load_unwind):
2968 * nsmenu.m (pop_down_menu):
2969 * print.c (print_object) [GC_MARK_STACK]:
2970 * xfns.c (clean_up_file_dialog):
2971 * xmenu.c (cleanup_widget_value_tree):
2972 Omit casts between XSAVE_POINTER and a pointer type.
2974 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>

2977 * eval.c (eval_sub): Protect `form' from being GCed before its
2978 car and cdr becomes protected with the backtrace entry.
2980 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2982 Make Lisp_Save_Value more versatile storage for up to four objects.

2992 (free_save_value): Likewise.
2993 (mark_object): Likewise.
2994 * editfns.c (save_excursion_save): Pack everything within
2995 Lisp_Save_Value and so avoid xmalloc.
2996 (save_excursion_restore): Adjust to match new layout. Use free_misc
2997 because we do not allocate extra memory any more. Add eassert.
2998 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2999 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

3009 Bug#11484 with LCD smoothing on.
3011 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
3013 Fix SIGDANGER handlers, for AIX (Bug#13408).
3014 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
3015 Move handlers here from emacs.c; they were out of place.

3067 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
3069 Avoid unnecessary byte position calculation for the gap movement.
3070 Since all users of move_gap do CHAR_TO_BYTE for other purposes
3071 anyway, all of them should use move_gap_both instead.

3083 * term.c (init_tty): Use them instead of rolling our own code.
3084 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
3085 switches from 'signal' to 'pthread_sigmask', which is safer in
3086 multithreaded applications.
3087 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
3088 which has already arranged for that.
3089 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.

3100 the type of per-buffer values where appropriate.
3101 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
3102 predicate, which is how it's really used now. Adjust comment.
3103 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
3104 * buffer.c (buffer_slot_type_mismatch): Remove.
3105 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

3110 right-fringe-width, scroll-bar-width and buffer-display-count.
3111 Use Qstringp for default-directory, buffer-file-name,
3112 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
3113 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
3115 * data.c (store_symval_forwarding): Adjust to call the predicate.

3158 trailing dash is properly added.
3160 2013-01-05 Eli Zaretskii <eliz@gnu.org>
3162 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
3163 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
3164 digits for buffer positions, before misalignment starts.
3165 Display "0" for integer "object" field.
3166 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
3167 Display the newline glyph more unambiguously.

3239 * xterm.h (struct x_output): Surround handlebox_widget with
3240 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
3241 toolbar_in_hbox is bool.
3243 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
3245 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
3246 (LIBS_GNUSTEP): Define.
3247 (LIBES): Add $(LIBS_GNUSTEP).
3248 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
3250 2012-12-30 Eli Zaretskii <eliz@gnu.org>
3252 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
3253 continuation glyph on a TTY with an indication of an empty line.
3256 2012-12-29 Eli Zaretskii <eliz@gnu.org>
3258 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
3259 file's SELinux context or ACLs successfully set, nil otherwise.
3261 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
3263 * w32proc.c (reader_thread): Avoid passing NULL handles to
3264 SetEvent and WaitForSingleObject.
3266 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
3268 Port EXTERNALLY_VISIBLE to Clang 3.2.
3269 * conf_post.h (__has_attribute): New macro.
3270 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
3272 2012-12-27 Glenn Morris <rgm@gnu.org>
3274 * cygw32.c (Fcygwin_convert_file_name_to_windows)
3275 (Fcygwin_convert_file_name_from_windows): Doc fixes.
3277 2012-12-27 Eli Zaretskii <eliz@gnu.org>
3279 * fileio.c (file_name_as_directory, directory_file_name):
3280 Accept an additional argument MULTIBYTE to indicate whether the input C
3281 came from a multibyte or a unibyte Lisp string; all callers
3282 adjusted. Don't assume the input string is always multibyte.
3284 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
3285 don't ENCODE_FILE them, and return a unibyte string if the input
3287 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
3288 don't assume the input strings will always be multibyte. If the
3289 input strings are multibyte, decode strings obtained from C
3292 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
3294 * lisp.h (toplevel): Add two notices to the comment about
3295 defining a new Lisp data type.
3296 * print.c (print_object): If Lisp_Save_Value object's pointer
3297 is the address of a memory area containing Lisp_Objects, try
3299 * alloc.c (valid_lisp_object_p): Adjust comment.
3301 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
3303 * keyboard.c (record_asynch_buffer_change): Initialize an event
3304 only if it's really needed.
3305 * frame.h (enum output_method): Remove output_mac member since
3306 it's a leftover from the deleted code.
3307 * frame.c (Fframep): Adjust user here ...
3308 * terminal.c (Fterminal_live_p): ... and here.
3309 * coding.c (Qmac): Now here because it's only used to denote
3310 end-of-line encoding type.
3311 (syms_of_coding): DEFSYM it.
3312 * frame.h (Qmac): Remove duplicated declaration.
3314 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
3316 * window.c (select_window_1): Now static, since it's used only here.
3318 2012-12-25 Eli Zaretskii <eliz@gnu.org>
3320 * window.c (window_body_cols): Subtract display margins from the
3321 window body width on TTYs as well. See
3322 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
3323 for the original report.
3325 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
3327 * xdisp.c (redisplay_window): Remove inner local variable
3328 because the outer shadowed one has the same meaning.
3329 * xterm.h (struct x_output): Remove toolbar_detached member since it's
3331 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
3332 (xg_create_tool_bar): Adjust users.
3334 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
3336 * buffer.h (BUF_COMPACT): New macro to follow the common style.
3337 * buffer.c (Fget_buffer_create): Use it to set compact field of
3338 struct buffer_text to avoid accessing an uninitialized value
3339 when compact_buffer is called for the first time.
3340 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
3341 (Fset_buffer_modified_p): Use buffer_window_count to check
3342 whether the buffer is displayed in some window.
3343 * xdisp.c (message_dolog): Likewise.
3345 2012-12-23 Eli Zaretskii <eliz@gnu.org>
3347 * w32.c (acl_set_file): If setting the file security descriptor
3348 fails, and the new DACL is identical to the existing one, silently
3349 return success. This fixes problems for users backing up their
3350 own files without having the necessary privileges for setting
3351 security descriptors.
3353 * w32proc.c (reader_thread): Do not index fd_info[] with negative
3355 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
3356 after WaitForSingleObject returns normally. This expedites reader
3357 thread shutdown when delete_child triggers it.
3358 (reap_subprocess): More accurate commentary for why we call
3359 delete_child only when cp->fd is negative.
3361 * w32.c (sys_close): Do not call delete_child on a subprocess
3362 whose handle is not yet closed. Instead, set its file descriptor
3363 to a negative value, so that reap_subprocess will call
3364 delete_child on that subprocess when its SIGCHLD arrives.
3365 This avoids closing handles used for communications between sys_select
3366 and reader_thread, which doesn't give sys_select a chance to
3367 notice that the process exited and invoke the SIGCHLD handler for
3370 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
3372 * nsfns.m (Fns_do_applescript): Run event loop until script has
3373 been executed (Bug#12969).
3374 (ns_run_ascript): Chech as_script for nil, set to nil after
3377 2012-12-22 Martin Rudalics <rudalics@gmx.at>
3379 * window.c (Fselect_window): Reword doc-string (Bug#13248).
3381 2012-12-22 Eli Zaretskii <eliz@gnu.org>
3383 * w32term.c (w32fullscreen_hook): New function.
3384 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
3386 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3388 * fileio.c (Finsert_file_contents): Doc fix.
3390 * w32proc.c (new_child, delete_child, find_child_pid): For a
3391 subprocess, consider its slot being in use as long as its process
3392 handle (procinfo.hProcess) is not NULL. This avoids reusing the
3393 slot when a new process is started immediately after killing
3394 another one, without waiting enough time for the first process to
3395 be reaped and resources allocated for it be orderly freed.
3397 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
3399 2012-12-21 Chong Yidong <cyd@gnu.org>
3401 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
3403 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
3405 2012-12-21 Eli Zaretskii <eliz@gnu.org>
3407 * w32.c (get_name_and_id): Always pass NULL as the first argument
3408 of lookup_account_sid. Avoids crashes with UNC file names that
3409 refer to DFS domains, not to specific machine names. (Bug#12621)
3410 Remove now unused argument FNAME; all callers changed.
3411 (get_file_owner_and_group): Remove now unused argument FNAME; all
3414 2012-12-21 Chong Yidong <cyd@gnu.org>
3416 * editfns.c (Finsert_char): Since read-char-by-name now signals an
3417 error for invalid chars, don't check for a nil return value.
3419 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3421 Avoid calls to CHAR_TO_BYTE if byte position is known.
3422 * editfns.c (make_buffer_string_both): Use move_gap_both.
3423 (Fbuffer_string): Use make_buffer_string_both.
3424 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
3426 (buf_bytepos_to_charpos): Likewise.
3427 (charpos_to_bytepos): Remove.
3428 * fileio.c (Finsert_file_contents): Use move_gap_both.
3429 * search.c (Freplace_match): Likewise.
3430 * process.c (process_send_region): Likewise. Use convenient
3431 names for byte positions.
3432 * lisp.h (charpos_to_bytepos): Remove prototype.
3433 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
3434 * insdel.c (move_gap): Likewise.
3436 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
3438 * xdisp.c (redisplay_internal): Remove now-unused local.
3440 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
3442 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
3443 (redisplay_internal): Don't bother selecting the frame to get the
3444 proper value of frame-local variables (bug#13225).
3446 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3448 * textprop.c (set_text_properties_1): Do not allow NULL interval.
3449 Rename 4th argument since it may be buffer or string. Adjust comment.
3450 * intervals.c (graft_intervals_info_buffer): Find an interval here.
3452 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
3454 * coding.c (Fdetect_coding_region): Do not check start and end with
3455 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
3456 (code_convert_region): Likewise.
3458 2012-12-18 Eli Zaretskii <eliz@gnu.org>
3460 * w32.c (acl_get_file, acl_set_file): Run the file name through
3461 map_w32_filename, and resolve any symlinks in the file name, like
3463 (acl_set_file): Call revert_to_self, if any privileges were
3466 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
3468 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
3469 ($(BLD)/w32.$(O)): Update dependencies.
3471 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
3473 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
3474 propagate redisplay's scrolling (if any) to the right window.
3475 (redisplay_internal): Use ensure_selected_frame.
3476 (display_mode_lines): Complete last fix.
3477 * window.c (select_window_1): New func, extracted from select_window.
3478 (select_window): Use it.
3479 * window.h (select_window_1): Declare.
3481 2012-12-17 Eli Zaretskii <eliz@gnu.org>
3483 Emulate Posix ACL APIs on MS-Windows.
3484 * w32.c: Include sddl.h and sys/acl.h.
3485 (SDDL_REVISION_1): Define if not already defined.
3486 (g_b_init_get_security_descriptor_dacl)
3487 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
3488 (g_b_init_is_valid_security_descriptor)
3489 (g_b_init_set_file_security): New static flags.

3500 (convert_sddl_to_sd, acl_valid, acl_to_text, acl_from_text)
3501 (acl_free, acl_get_file, acl_set_file): New functions.
3503 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
3505 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
3507 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
3508 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
3509 for some of that bug's symptoms can now cause Emacs to abort.
3510 Remove the workaround.
3511 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
3512 The bug that caused SIGCHLD to get lost has been fixed, and the
3513 workaround for it can now cause Emacs to abort.
3515 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
3517 * sysdep.c (emacs_abort): Bump backtrace size to 40.
3518 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
3519 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
3521 2012-12-16 Romain Francoise <romain@orebokech.com>
3523 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
3524 (Fcopy_file): Change last arg to `preserve_extended_attributes'
3525 and copy ACL entries of file in addition to SELinux context if set.
3526 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
3528 * Makefile.in (LIBACL_LIBS): New macro.
3531 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
3533 * fileio.c (internal_delete_file): Use bool for boolean.
3535 2012-12-15 Eli Zaretskii <eliz@gnu.org>
3537 Fix bug #13079 on MS-Windows with temp files not being deleted.

3540 (register_child): First argument is now pid_t.
3541 (record_infile, record_pending_deletion): New prototypes.
3543 * w32proc.c (new_child): Initialize input_file and
3544 pending_deletion members of the child.
3545 (delete_child): Delete the child's temporary input file, if any,
3546 that is pending deletion.
3547 (register_child): First argument is now pid_t.
3548 (record_infile, record_pending_deletion): New functions.
3549 (reap_subprocess): Fix a typo in DebPrint string.
3550 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
3552 * fileio.c (internal_delete_file): Return an int again: non-zero
3553 if delete-file succeeds, zero otherwise.
3555 * lisp.h (internal_delete_file): Adjust prototype.
3557 * callproc.c (Fcall_process): Don't overwrite infile with result
3559 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
3560 asynchronous subprocess, record the name of the input file name,
3562 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
3563 delete the file, record it as pending deletion when the subprocess
3566 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3568 * editfns.c [HAVE_PWD_H]: Include grp.h.
3570 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
3572 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
3574 Fix permissions bugs with setgid directories etc. (Bug#13125)
3575 * dired.c (Ffile_attributes): Return t as the 9th attribute,
3576 to mark it as a placeholder. The old value was often wrong.
3577 The only user of this attribute has been changed to use
3578 file-ownership-preserved-p instead, with its new group arg.
3579 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
3581 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

3586 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3588 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
3589 try to get accurate owner and group information from NT file
3590 security APIs. This is to make most callers of 'stat' and
3591 'lstat', which don't need that information, much faster.
3593 * dired.c (Ffile_attributes) [WINDOWSNT]:
3594 Set w32_stat_get_owner_group to a non-zero value, to request accurate
3595 owner and group information from 'lstat'.
3597 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3599 * fileio.c (Finsert_file_contents): Don't put tail into head area,
3600 as that confuses set-auto-coding, so insist on the head-read
3601 returning the full 1024 bytes. Let lseek compute the tail offset;
3602 less work for us. Do not ignore I/O errors when reading the tail.
3604 * xdisp.c: Minor style fixes.
3605 (init_iterator): Hoist assignment out of if-expression.
3606 (markpos_of_region): Callers now test for sign, not for -1.
3608 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
3610 Minor redisplay optimization when the region length is zero.
3611 * xdisp.c (markpos_of_region): New function.
3612 (init_iterator): Do not highlight the region of zero length.
3613 (redisplay_window): Check whether the region is of non-zero length.
3614 (try_cursor_movement): Allow if the region length is zero.
3615 (try_window_reusing_current_matrix, try_window_id): Likewise.
3617 2012-12-13 Eli Zaretskii <eliz@gnu.org>
3619 * search.c (search_buffer): Check the inverse translations of each
3620 character in pattern when the buffer being searched is unibyte.
3623 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3625 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
3626 files, fixing a regression from 24.2.
3627 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
3629 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3631 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
3632 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3633 Remove unnecessary S_ISLNK test, as (contra the comments) this
3634 function can't copy symlinks. Improve quality of error message
3635 when attempting to copy files that are neither regular files nor
3638 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
3640 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.

3642 * window.c (Frecenter):
3643 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
3644 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
3646 2012-12-12 Daniel Colascione <dancol@dancol.org>
3648 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
3649 the dumped Emacs is not a sparse file, greatly improving Cygwin
3650 "make bootstrap" performance.
3652 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
3654 * inotify.c (inotify_callback): Generate an Emacs event for every
3655 incoming inotify event.
3657 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3659 * xdisp.c (handle_face_prop): Fix logic of computing
3660 it->start_of_box_run_p.
3661 (append_space_for_newline): If the glyph row is R2L, reset the
3662 iterator's end_of_box_run_p flag before prepending the space glyph.
3663 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
3664 iterator's start_of_box_run_p flag before prepending the stretch.
3665 (append_glyph, produce_image_glyph, append_composite_glyph)
3666 (append_stretch_glyph, append_glyphless_glyph): Reverse the
3667 left_box_line_p and right_box_line_p flags of the glyph for R2L
3668 glyph rows. (Bug#13011)
3670 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
3672 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
3673 if changed buffer is not shown in a window.
3674 * insdel.c (prepare_to_modify_buffer): Likewise.
3675 * window.c (replace_buffer_in_windows_safely): Do nothing
3676 if buffer is not shown in a window.
3677 (Fforce_window_update): Likewise if string or buffer argument
3680 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3682 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
3683 encoded_file_name, which is what it is.
3685 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
3687 Consistently use marker_position and marker_byte_position.
3688 * fringe.c (Ffringe_bitmaps_at_pos):
3689 * indent.c (Fvertical_motion):
3690 * insdel.c (prepare_to_modify_buffer):
3691 * keyboard.c (make_lispy_position):

3695 * xdisp.c (message_dolog, with_echo_area_buffer_unwind_data)
3696 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
3697 Replace direct access to marker fields with calls
3698 to marker_position and/or marker_byte_position.
3700 2012-12-11 Juanma Barranquero <lekktu@gmail.com>
3702 * makefile.w32-in (SIG2STR_H): New macro.
3703 (SYSWAIT_H, $(BLD)/emacs.$(O), $(BLD)/process.$(O))
3704 ($(BLD)/w32notify.$(O)): Update dependencies.
3706 2012-12-10 Daniel Colascione <dancol@dancol.org>
3708 * w32term.c, keyboard.c: Fix build break in cygw32 by omitting
3709 Windows file notification functionality unless WINDOWSNT.
3711 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
3714 * w32fns.c (cache_system_info): Initialize the global hinst

3718 (hinst): Remove unneeded extern declaration.
3719 (_start): Remove initialization of above variables; remove

3723 previously weren't calling it in Cygwin builds.
3725 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
3726 Teach the autoconf build system how to compile a Windows resource file

3864 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3866 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).

3868 * dbusbind.c (Fdbus_init_bus):
3870 * xterm.c (x_term_init):

3881 no longer needed here.
3882 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
3883 Move to inside set_time_zone_rule; they don't need file scope any more.
3884 (set_time_zone_rule): Maintain the TZ=value string separately.
3885 (syms_of_editfns): Don't initialize initial_tz;
3886 init_editfns now does it.
3887 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
3888 * lisp.h (xputenv): New decl.
3890 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
3892 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
3894 2012-12-08 Eli Zaretskii <eliz@gnu.org>

3901 informative (Bug#12992).
3903 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3905 Simplify get_lim_data.
3906 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3907 Remove USG and vlimit methods; no longer used these days.
3908 Add #error catchall just in case.
3910 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3911 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3912 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
3913 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
3914 (deleted_pid_list, Fdelete_process, create_process)
3915 (record_child_status_change, handle_child_signal, deliver_child_signal)

3920 (Fsignal_process): Use it to convert signal names to ints.

3931 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
3933 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
3934 This will cause a production Emacs to dump core instead of
3937 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3939 * frame.c (make_frame): Do not set window's buffer to t.
3940 * window.c (Fsplit_window_internal): Likewise. Previously it was
3941 used to indicate that the window is being set up. Now we use
3942 set_window_buffer for all new windows, so the condition in ...
3943 (Fset_window_buffer): ... is always true and can be removed.
3945 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3947 Convenient macro to check whether the buffer is hidden.
3948 * buffer.h (BUFFER_HIDDEN_P): New macro.
3949 * frame.c (make_frame): Use it. Adjust comment.
3950 * buffer.c (candidate_buffer): New function.
3951 (Fother_buffer, other_buffer_safely): Use it.
3953 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3955 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
3956 if the child process is still running. Instead, exit the wait
3957 loop and return zero. (Bug#13086)
3959 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3961 * frame.h (x_char_width, x_char_height): Remove prototypes.

3975 * callproc.c, process.h (record_kill_process):
3976 New function, containing part of the old call_process_kill.
3977 (call_process_kill): Use it.
3978 This does not change call_process_kill's behavior.
3979 * process.c (Fdelete_process): Use record_kill_process to fix a
3980 race condition that could cause Emacs to lose track of a child.
3982 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3984 Avoid code duplication between prev_frame and next_frame.
3985 * frame.c (candidate_frame): New function. Add comment.
3986 (prev_frame, next_frame): Use it. Adjust comment.
3988 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3990 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3991 fails, signal an error instead of continuing with an empty
3993 Encode expanded temp file pattern before passing it to mkstemp or
3996 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3997 Encode the file name before passing it to dostounix_filename, in
3998 case it will downcase it (under w32-downcase-file-names).
4001 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
4003 Minor call-process cleanups.
4004 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
4005 at the same time as other platforms, to simplify analysis.
4006 No need for fd0_volatile since we have synch_process_fd.
4007 Avoid needless emacs_close; arg is always negative.
4009 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
4011 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
4014 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
4016 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
4017 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
4018 and mouse_face_hidden members to a bitfields.

4020 (FRAME_SPACE_WIDTH): Remove.
4021 * nsterm.m, w32term.c, xterm.c: Adjust users.
4022 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
4023 member. Adjust users. Convert term_initted, delete_in_insert_mode,
4024 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
4025 members to a bitfields.
4027 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
4029 Don't let call-process be a zombie factory (Bug#12980).
4030 Fixing this bug required some cleanup of the signal-handling code.
4031 As a side effect, this change also fixes a longstanding rare race
4032 condition whereby Emacs could mistakenly kill unrelated processes,
4033 and it fixes a bug where a second C-g does not kill a recalcitrant
4034 synchronous process in GNU/Linux and similar platforms.
4035 The patch should also fix the last vestiges of Bug#9488,
4036 a bug which has mostly been fixed on the trunk by other changes.
4037 * callproc.c, process.h (synch_process_alive, synch_process_death)
4038 (synch_process_termsig, sync_process_retcode):
4039 Remove. All uses removed, to simplify analysis and so that
4040 less consing is done inside critical sections.
4041 * callproc.c (call_process_exited): Remove. All uses replaced
4042 with !synch_process_pid.
4043 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
4044 These take the role of what used to be in unwind-protect arg.
4046 (block_child_signal, unblock_child_signal):
4047 New functions, to avoid races that could kill innocent-victim processes.
4048 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
4049 (call_process_kill): Record killed processes as deleted, so that
4050 zombies do not clutter up the system. Do this inside a critical
4051 section, to avoid a race that would allow the clutter.
4052 (call_process_cleanup): Fix code so that the second C-g works again
4053 on common platforms such as GNU/Linux.
4054 (Fcall_process): Create the child process in a critical section,
4055 to fix a race condition. If creating an asynchronous process,
4056 record it as deleted so that zombies do not clutter up the system.
4057 Do unwind-protect for WINDOWSNT too, as that's simpler in the
4058 light of these changes. Omit unnecessary call to emacs_close
4059 before failure, as the unwind-protect code does that.
4060 * callproc.c (call_process_cleanup):
4061 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
4062 * process.c (record_deleted_pid): New function, containing
4063 code refactored out of Fdelete_process.
4064 (Fdelete_process): Use it.
4065 (process_status_retrieved): Remove. All callers changed to use
4066 child_status_change.
4067 (record_child_status_change): Remove, folding its contents into ...
4068 (handle_child_signal): ... this signal handler. Now, this
4069 function is purely a handler for SIGCHLD, and is not called after
4070 a synchronous waitpid returns; the synchronous code is moved to
4071 wait_for_termination. There is no need to worry about reaping
4072 more than one child now.
4073 * sysdep.c (get_child_status, child_status_changed): New functions.
4074 (wait_for_termination): Now takes int * status and bool
4075 interruptible arguments, too. Do not record child status change;
4076 that's now the caller's responsibility. All callers changed.
4077 Reimplement in terms of get_child_status.
4078 (wait_for_termination_1, interruptible_wait_for_termination):
4079 Remove. All callers changed to use wait_for_termination.
4080 * syswait.h: Include <stdbool.h>, for bool.
4081 (record_child_status_change, interruptible_wait_for_termination):
4083 (record_deleted_pid, child_status_changed): New decls.
4084 (wait_for_termination): Adjust to API changes noted above.
4086 * bytecode.c, lisp.h (Qbytecode): Remove.
4087 No longer needed after 2012-11-20 interactive-p changes.
4089 2012-12-03 Eli Zaretskii <eliz@gnu.org>
4091 * xdisp.c (redisplay_window): If the cursor is visible, but inside
4092 the scroll margin, move point outside the margin. (Bug#13055)

4096 * gtkutil.c (my_log_handler): New function.
4097 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
4099 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
4101 * lisp.h (modify_region): Rename to...
4102 (modify_region_1): ...new prototype.
4103 * textprop.c (modify_region): Now static. Adjust users.
4104 * insdel.c (modify_region): Rename to...
4105 (modify_region_1): ...new function to work with current buffer.
4106 Adjust comment and users. Use true and false for booleans.
4108 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
4110 * alloc.c (free_save_value): New function.
4111 (safe_alloca_unwind): Use it.
4112 * lisp.h (free_save_value): New prototype.
4113 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
4115 (save_excursion_restore): Adjust to match saved data structure.
4116 Use free_save_value to offload some work from GC. Drop obsolete
4119 2012-12-03 Chong Yidong <cyd@gnu.org>
4121 * fileio.c (Vauto_save_list_file_name): Doc fix.
4123 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
4125 * w32fns.c: Remove prototype of atof.

4128 (file_dialog_callback): Make it UINT_PTR.
4130 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
4133 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4134 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
4137 2012-12-03 Glenn Morris <rgm@gnu.org>
4139 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
4141 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
4143 Fix xpalloc confusion after memory is exhausted.
4144 * alloc.c (xpalloc): Comment fix.
4145 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
4146 and signals an error, do not clear charset_table_size, as
4147 charset_table is still valid.
4148 * doprnt.c (evxprintf): Clear *BUF after freeing it.
4150 Use execve to avoid need to munge environ (Bug#13054).
4151 * callproc.c (Fcall_process):
4152 * process.c (create_process):
4153 Don't save and restore environ; no longer needed.
4154 * callproc.c (child_setup):
4155 Use execve, not execvp, to preserve environ.
4157 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
4159 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).

4171 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
4173 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
4175 * xdisp.c (window_outdated): Remove eassert since it hits
4176 some suspicious corner cases (see Bug#13007 and Bug#13012).

4186 * callproc.c (Fcall_process): Don't misreport vfork failure.
4188 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
4190 * callproc.c (Fcall_process): Fix vfork portability problems.
4191 Do not assume that fd[0], count, filefd, and save_environ survive
4192 vfork. Fix bug whereby wrong errno value could be reported for
4193 pipe failure. Some minor cleanups, too, as follows. Move buf and
4194 bufsize to the context where they're needed. Change new_argv to
4195 be of type char **, as this is more convenient and avoids casts.
4196 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
4197 Now local constants, not macros.
4199 2012-11-18 Kenichi Handa <handa@gnu.org>
4201 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
4202 for the variable "f".
4204 2012-11-13 Kenichi Handa <handa@gnu.org>
4206 * font.c (font_unparse_xlfd): Exclude special characters from the
4207 generating XLFD name.
4209 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
4211 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
4212 * dired.c (stat_uname, stat_gname):
4213 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
4215 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

4219 * fileio.c (Fcopy_file): Assume EISDIR is defined.
4220 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
4221 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
4222 * lread.c (readbyte_from_file): Assume EINTR is defined.
4223 * process.c (wait_reading_process_output, send_process) [subprocesses]:
4224 Assume EIO and EAGAIN are defined.
4225 * unexcoff.c (write_segment): Assume EFAULT is defined.
4227 2012-11-27 Eli Zaretskii <eliz@gnu.org>
4229 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
4232 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
4233 highlighting on the frame was cleared. Prevents assertion
4234 violations when repeatedly clicking on the "Top" link of the
4235 "bread-crumbs" in Info buffers.
4237 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
4239 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
4241 2012-11-24 Ken Brown <kbrown@cornell.edu>
4243 * keyboard.c (HAVE_MOUSE):
4244 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
4245 were always defined.
4247 2012-11-24 Eli Zaretskii <eliz@gnu.org>
4249 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
4250 between bpos_covered and bpos_max. This fixes cursor display when
4251 several display strings follow each other.
4253 * .gdbinit (pgx): If the glyph's object is a string, display the
4254 pointer to string data, rather than the value of the string object
4255 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
4257 * indent.c (Fvertical_motion): If the starting position is covered
4258 by a display string, return to one position before that, to avoid
4259 overshooting it inside move_it_to. (Bug#12930)
4261 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
4263 * frame.h (struct frame): Remove display_preempted member
4264 since all users are dead long ago.
4265 * nsterm.h (struct x_output): Use the only dummy member.
4266 * w32menu.c (pending_menu_activation): Remove since not
4268 (set_frame_menubar): Adjust user.
4269 * w32term.h (struct x_output): Drop outdated #if 0 code.
4270 (struct w32_output): Use bitfields for explicit_parent,
4271 asked_for_visible and menubar_active members.
4272 Drop unused pending_menu_activation member.
4273 * xterm.h (struct x_output): Drop outdated #if 0 code.
4274 Use bitfields for explicit_parent, asked_for_visible,
4275 has_been_visible and net_wm_state_hidden_seen members.
4277 2012-11-23 Eli Zaretskii <eliz@gnu.org>
4279 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
4280 of a literal "/". (Bug#12955)
4281 (gl-stamp): Invoke fc.exe directly, not through cmd.
4283 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
4285 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
4286 * dired.c: Assume HAVE_DIRENT_H.
4287 (NAMLEN): Remove, replacing with ...
4288 (dirent_namelen): New function. All uses changed. Use the GNU macro
4289 _D_EXACT_NAMELEN if available, as it's faster than strlen.
4290 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
4291 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
4292 * makefile.w32-in (DIR_H): Remove. All uses replaced with
4294 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
4295 * ndir.h: Rename to ../nt/inc/dirent.h.
4296 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
4297 Do not include <dirent.h>; no longer needed.
4298 * w32.c: Include <dirent.h> rather than "ndir.h".
4300 2012-11-23 Chong Yidong <cyd@gnu.org>
4302 * xftfont.c (xftfont_open): Remove duplicate assignment.
4304 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4306 * alloc.c (Fgarbage_collect): Unblock input after clearing
4307 gc_in_progress to avoid note_mouse_highlight glitch with GC.
4308 * frame.h (FRAME_MOUSE_UPDATE): New macro.
4309 * msdos.c (IT_frame_up_to_date): Use it here...
4310 * w32term.c (w32_frame_up_to_date): ...here...
4311 * xterm.c (XTframe_up_to_date): ...and here...
4312 * nsterm.m (ns_frame_up_to_date): ...but not here.
4313 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
4315 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
4316 Do not check whether GC is in progress.
4318 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
4320 * xdisp.c (window_buffer_changed): New function.
4321 (update_menu_bar, update_tool_bar): Use it to
4322 simplify large 'if' statements.
4323 (redisplay_internal): Generalize commonly used
4324 'tail' and 'frame' local variables.
4326 2012-11-22 Eli Zaretskii <eliz@gnu.org>
4328 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
4329 with Windows system header.
4331 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
4333 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
4334 * alloc.c: Assume unistd.h exists.
4335 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
4336 * sysdep.c (get_current_dir_name): Assume getcwd exists.
4337 (getwd) [USG]: Remove; no longer needed.
4338 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
4339 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
4340 * w32.h (getcwd): Remove decl.
4342 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
4344 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
4345 Make it set selected_window as well.
4346 (update_tool_bar): Use it.
4348 2012-11-21 Ken Brown <kbrown@cornell.edu>
4350 * emacs.c (main): Set the G_SLICE environment variable for all
4351 Cygwin builds, not just GTK builds. See
4352 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
4354 2012-11-21 Eli Zaretskii <eliz@gnu.org>
4356 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
4357 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
4358 Define for the MSVC compiler.
4360 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
4362 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
4363 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
4364 dostounix_filename. Prevents crashes down the road, because
4365 dostounix_filename assumes it gets a unibyte string.
4366 Reported by Michel de Ruiter <michel@sentient.nl>, see
4367 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
4369 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

4373 * lread.c (init_obarray): Set `function' fields to Qnil.
4374 * eval.c (Fcommandp): Ignore Qunbound.
4375 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
4376 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
4377 Test NILP rather than Qunbound.
4378 (Ffmakunbound): Set to Qnil.
4379 (Fsymbol_function): Never signal an error.
4380 (Finteractive_form): Ignore Qunbound.
4382 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
4384 * eval.c (interactive_p): Remove no-longer-used decl.
4386 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
4388 * xdisp.c (buffer_shared): Adjust comment.
4389 (buffer_shared_and_changed): New function.
4390 (prepare_menu_bars, redisplay_internal): Use it to
4391 decide whether all windows or frames should be updated.
4392 (window_outdated): New function.
4393 (text_outside_line_unchanged_p, redisplay_window): Use it.
4394 (redisplay_internal): Likewise. Fix indentation.
4396 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
4398 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
4399 (syms_of_eval): Remove corresponding defsubr.
4400 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
4402 2012-11-19 Daniel Colascione <dancol@dancol.org>
4404 * w32fns.c (Fx_file_dialog):
4405 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
4406 cygwin_convert_file_name*.
4408 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
4409 Rename cygwin_convert_path* to cygwin_convert_file_name*.
4411 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
4413 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
4415 2012-11-18 Eli Zaretskii <eliz@gnu.org>
4417 * w32select.c: Include w32common.h before w32term.h, so that
4418 windows.h gets included before w32term.h uses some of its
4419 features, see below.
4421 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
4423 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
4425 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
4427 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
4429 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
4430 (ns_select): Return at once if events are held (Bug#12834).
4432 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
4434 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
4435 Needed following 2012-10-20 change. (Bug#12902)
4437 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
4439 * w32proc.c (waitpid): Remove unused label get_result.
4441 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
4443 * makefile.w32-in (SYSWAIT_H): New macro.
4444 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
4445 ($(BLD)/sysdep.$(O)): Update dependencies.
4447 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4449 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
4450 * callproc.c (relocate_fd): Assume F_DUPFD.
4451 * emacs.c, term.c (O_RDWR): Remove.
4452 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
4453 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
4454 * nsterm.m: Assume <fcntl.h> exists.
4455 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
4456 (create_pty, Fmake_network_process, server_accept_connection)
4457 (wait_reading_process_output, init_process_emacs):
4459 (wait_reading_process_output): Put in a special case for WINDOWSNT
4460 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
4461 It's not clear this is needed, but it's a more-conservative change.
4462 (create_process): Assume FD_CLOEXEC.
4463 (create_process, create_pty): Assume O_NOCTTY.
4464 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
4465 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
4466 Omit if not DOS_NT, since F_GETFL is not defined there.
4467 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
4468 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
4470 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
4471 lack it, since gnulib guarantees this.
4472 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
4474 2012-11-17 Eli Zaretskii <eliz@gnu.org>
4476 * w32.c (faccessat): Pretend that directories have the execute bit
4477 set. Emacs expects that, e.g., in files.el:cd-absolute.
4479 * w32proc.c (create_child): Don't clip the PID of the child
4480 process to fit into an Emacs integer, as this is no longer a
4482 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
4483 reaping only the process specified by PID argument, if that is
4484 positive. Use PID instead of dead_child to know which process to
4485 reap. Wait for the child to die only if WNOHANG is not in
4487 (sys_select): Don't set dead_child.
4489 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
4490 as it is no longer needed.
4492 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
4494 (record_child_status_change): Remove the setting of
4495 record_at_most_one_child for the !WNOHANG case.
4497 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4499 Fix problems in ns port found by static checking.
4500 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
4501 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
4502 not to process group.
4503 (ns_select): Use emacs_write, not write, as that's more robust
4504 in the presence of signals.
4505 (fd_handler:): Check for read errors.
4507 2012-11-16 Glenn Morris <rgm@gnu.org>
4509 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
4511 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
4513 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
4515 2012-11-16 Eli Zaretskii <eliz@gnu.org>
4517 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
4518 use the same value of thread handle.
4519 (start_timer_thread): If the timer thread exited (due to error),
4520 clean up by closing the two handles it used. Duplicate the caller
4521 thread's handle here, so it gets duplicated only once, when
4522 launching the timer thread. Set priority of the timer thread, not
4524 (getitimer): Don't duplicate the caller thread's handle here.
4527 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
4529 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
4532 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
4534 Remove no-longer-used pty_max_bytes variable.
4535 * process.c (pty_max_bytes): Remove; unused.
4536 (send_process): Do not set it.
4538 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
4540 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
4541 Update dependencies.
4543 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
4545 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
4546 This follows up on the 2012-09-29 patch that removed indirection
4547 for the 'function' field. Reported by Sergey Vinokurov in
4548 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
4550 2012-11-14 Eli Zaretskii <eliz@gnu.org>
4552 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
4553 different name, as the MS runtime does not have such a function,
4554 and probably never will.) All callers changed. Ignore DIRFD
4555 value if PATH is an absolute file name, to match Posix spec
4556 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
4559 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
4561 * xdisp.c (echo_area_display, redisplay_internal):
4562 Omit redundant check whether frame_garbaged is set.
4564 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
4566 Use faccessat, not access, when checking file permissions (Bug#12632).
4567 This fixes a bug that has been present in Emacs since its creation.
4568 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
4569 which must set some sort of record. (Torek's bug report was against
4570 a predecessor of GNU Emacs, but GNU Emacs happened to have the
4571 same common flaw.) See Torek's Usenet posting
4572 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
4573 Posted: Fri Apr 8 14:18:56 1983.
4574 * Makefile.in (LIB_EACCESS): New macro.
4576 * callproc.c (init_callproc):
4577 * charset.c (init_charset):
4578 * fileio.c (check_existing, check_executable, check_writable)
4580 * lread.c (openp, load_path_check):
4581 * process.c (allocate_pty):
4583 Use effective UID when checking permissions, not real UID.
4584 * callproc.c (init_callproc):
4585 * charset.c (init_charset):
4586 * lread.c (load_path_check, init_lread):
4587 Test whether directories are accessible, not merely whether they exist.
4588 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
4589 * fileio.c (check_existing, check_executable, check_writable)
4591 Use symbolic names instead of integers for the flags, as they're
4593 (check_writable): New arg AMODE. All uses changed.
4594 Set errno on failure.
4595 (Ffile_readable_p): Use faccessat, not stat + open + close.
4596 (Ffile_writable_p): No need to call check_existing + check_writable.
4597 Just call check_writable and then look at errno. This saves a syscall.
4598 dir should never be nil; replace an unnecessary runtime check
4599 with an eassert. When checking the parent directory of a nonexistent
4600 file, check that the directory is searchable as well as writable, as
4601 we can't create files in unsearchable directories.
4602 (file_directory_p): New function, which uses 'stat' on most platforms
4603 but faccessat with D_OK (for efficiency) if WINDOWSNT.
4604 (Ffile_directory_p, Fset_file_times): Use it.
4605 (file_accessible_directory_p): New function, which uses a single
4606 syscall for efficiency.
4607 (Ffile_accessible_directory_p): Use it.
4608 * xrdb.c (file_p): Use file_directory_p.
4609 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
4610 * lread.c (openp): When opening a file, use fstat rather than
4611 stat, as that avoids a permissions race. When not opening a file,
4612 use file_directory_p rather than stat.
4613 (dir_warning): First arg is now a usage string, not a format.
4614 Use errno. All uses changed.
4615 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4616 that merely introduced a race.
4617 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4618 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4619 and similarly for the other O_* flags.
4620 * w32.c (sys_faccessat): Rename from sys_access and switch to
4621 faccessat's API. All uses changed.
4622 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4623 (magic_db): Rename from magic_file_p.
4624 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4625 char *, so that we don't have to test for file existence
4626 separately from opening the file for reading. This removes a race
4627 fixes a permission-checking problem, and simplifies the code.
4629 (file_p): Remove; no longer needed.
4631 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4633 Omit glyphs initialization at startup.
4634 * dispnew.c (glyphs_initialized_initially_p): Remove.
4635 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4636 (Fredraw_frame): Move actual code from here...
4637 (redraw_frame): ...to here. Add eassert. Adjust comment.

4644 passed to pint2str and pint2hrstr to be at most the size of the
4645 frame's decode_mode_spec_buffer. This avoids crashes with very
4646 large values of FIELD_WIDTH argument to decode_mode_spec.
4649 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4651 Fix a race with verify-visited-file-modtime (Bug#12863).
4652 Since at least 1991 Emacs has ignored an mtime difference of no
4653 more than one second, but my guess is that this was to work around
4654 file system bugs that were fixed long ago. Since the race is
4655 causing problems now, let's remove that code.
4656 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4657 whose time stamp is off by no more than a second. Insist that the
4658 file time stamps match exactly.
4660 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4662 * frame.h (struct frame): Convert external_tool_bar member to
4663 1-bit unsigned bitfield.

4680 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4681 (x_window_to_menu_bar): Likewise.
4682 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4684 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4686 * data.c (Qdefalias_fset_function): Now static.
4688 Another tweak to vectorlike_header change.

4690 Remove, and replace all uses with ...
4691 (next_in_free_list, set_next_in_free_list):
4692 New functions, which respect C's aliasing rules better.
4694 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4696 * window.c (list4i): Rename from 'quad'. All uses changed.
4697 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4699 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4701 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4702 warning about mixing declarations and code in ISO C90.
4704 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4706 * window.c (Fsplit_window_internal): Set combination limit of
4707 new parent window to t iff Vwindow_combination_limit is t;
4708 fixing a regression introduced with the change from 2012-09-22.
4709 (Fset_window_combination_limit): Fix doc-string.
4711 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4713 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4714 amount when the scroll margins are too large. When scrolling
4715 backwards in the buffer, give up if cannot reach point or the
4716 scroll margin within a reasonable number of screen lines.
4717 Fixes point position in window under scroll-up/down-aggressively when
4718 point is positioned many lines beyond the window top/bottom.
4721 * ralloc.c (relinquish): If real_morecore fails to return memory
4722 to the system, don't crash; instead, leave the last heap
4723 unchanged and return. (Bug#12774)

4732 (Finteractive_form): Simplify.
4733 (Fquo): Don't insist on having at least 2 arguments.
4734 (Qdefalias_fset_function): New var.
4736 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4738 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
4740 * nsfont.m (Qcondensed, Qexpanded): New variables.
4741 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
4742 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
4744 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4746 Fix recently introduced crash on MS-Windows (Bug#12839).
4747 * w32term.h (struct scroll_bar): Use convenient header.
4748 (SCROLL_BAR_VEC_SIZE): Remove.
4749 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4751 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4753 Tweak last vectorlike_header change.
4754 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4755 vectorlike object on the free list. This is introduced to avoid
4756 some (but not all) pointer casting and aliasing problems, see
4757 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4758 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

4762 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4764 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4765 been removed, so remove them here also.
4767 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4769 * doc.c (Fdocumentation): Handle new property
4770 dynamic-docstring-function to replace the old ad-advice-info.
4772 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4774 * fns.c (Qeql, hashtest_eq): Now static.
4776 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4778 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4779 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4780 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

4785 Use same hash function for hashfn_profiler as for hash_string etc.
4786 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
4787 * lisp.h (sxhash_combine): New inline function, with the contents
4788 of the old SXHASH_COMBINE.

4790 special hash function containing a comparison that always yields 1.
4792 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4794 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4795 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4796 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4799 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4801 * image.c (xpm_make_color_table_h): Fix compiler error because
4802 make_hash_table changed.
4804 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4806 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4808 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4810 Use ad-hoc comparison function for the profiler's hash-tables.
4811 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4812 (make_log): Use them.
4813 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4814 call Fequal any more.

4823 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4824 (hash_lookup, hash_remove_from_table): Move assertion checking of
4825 hashfn result here. Check hash-equality before calling cmpfn.

4827 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
4828 (syms_of_fns): Initialize them.

4838 value of w32-scroll-lock-modifier is neither nil nor one of the
4839 known key modifiers. (Bug#12806)
4841 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4843 Shrink struct vectorlike_header to the only size field.
4844 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4846 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4847 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4848 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4849 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4850 information from the vector header. Adjust comment.

4862 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
4863 (Fmake_bool_vector): Likewise.

4865 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4866 (large_vectors): Change type to struct large_vector.
4867 (allocate_vector_from_block): Simplify.
4868 (PSEUDOVECTOR_NBYTES): Replace with...
4869 (vector_nbytes): ...new function. Adjust users.

4871 (allocate_vectorlike): Likewise.
4872 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4873 Add easserts. Adjust XSETPVECTYPESIZE usage.
4874 (allocate_buffer): Use BUFFER_PVEC_INIT.
4875 (live_vector_p): Adjust to match large vector.
4876 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4877 * buffer.h (struct buffer): Add next member.
4878 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4880 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

4886 (xvecsize): New command.
4888 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4890 * keyboard.c (event_to_kboard): Do not dereference
4891 frame_or_window field of SELECTION_REQUEST_EVENT
4892 and SELECTION_CLEAR_EVENT events (Bug#12814).
4893 * xterm.h (struct selection_input_event): Adjust comment.
4895 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4897 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4898 such as Scroll Lock, if the respective keys are treated as
4899 function keys, not as modifiers. This avoids destroying non-ASCII
4900 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4902 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4904 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4906 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4908 Restore some duplicate definitions (Bug#12814).
4909 This undoes part of the 2012-11-03 changes. Some people build
4910 with plain -g rather than with -g3, and they need the duplicate
4911 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4912 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4913 Define as macros, as well as as enums or as constants.
4915 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4917 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4918 to keypad keys (Bug#12816).
4920 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4922 Minor adjustments of recently-changed frame functions.
4923 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4924 known to be a frame (we're in the FRAMEP branch).
4925 * lisp.h (Qframep): Remove decl. frame.h declares this.
4926 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4927 since they're meant for Lisp fixnum values.
4929 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4931 * window.c (Fwindow_combination_limit): Revert to the only
4932 required argument and adjust docstring as suggested in
4933 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4934 by Martin Rudalics <rudalics@gmx.at>.
4936 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>

4951 * lisp.h (frame_buffer_predicate): Remove prototype.
4952 * buffer.c (Fother_buffer): Use decode_any_frame.
4953 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4954 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4955 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4956 (Fclose_font, Ffont_info): Use decode_live_frame.
4957 * fontset.c (check_fontset_name): Likewise.
4958 * terminal.c (Fframe_terminal): Likewise.
4959 * w32fns.c (check_x_frame): Likewise.
4960 * window.c (Fminibuffer_window, Fwindow_at)
4961 (Fcurrent_window_configuration): Likewise.
4962 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
4963 Likewise. Allow zero number of arguments. Adjust docstring.
4964 * dispnew.c (Fredraw_frame): Likewise.
4965 * xfaces.c (frame_or_selected_frame): Remove.
4966 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4967 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4968 (Fframe_face_alist): Use decode_live_frame.
4969 * xfns.c (check_x_frame): Likewise.
4971 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4973 * window.c (quad): New function.
4974 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4975 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4976 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4977 (Fwindow_line_height): Use it.
4978 (Fwindow_fringes): Use list3.
4979 (Fwindow_scroll_bars): Use list4.
4980 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4981 (Fwindow_combination_limit): Allow zero number of arguments.
4983 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4985 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4987 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4988 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4989 file descriptor 2 for standard error. (Bug#12805)
4991 2012-11-05 Chong Yidong <cyd@gnu.org>
4993 * process.c (wait_reading_process_output): Revert previous change.
4995 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4997 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4998 This removes code that has been obsolete since around 1990.
4999 * callproc.c (Fcall_process):
5001 * process.c (create_process):
5002 * term.c (dissociate_if_controlling_tty):
5003 Assume setsid exists.
5004 * callproc.c (child_setup): Assume setpgid exists and behaves as
5005 per POSIX.1-1988 or later.
5006 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
5007 * emacs.c (shut_down_emacs):
5008 * sysdep.c (sys_suspend, init_foreground_group):
5009 Assume getpgrp behaves as per POSIX.1-1998 or later.
5010 * msdos.c (setpgrp): Remove.
5011 (tcgetpgrp, setpgid, setsid): New functions.
5012 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
5013 * term.c (no_controlling_tty): Remove; unused.
5014 * w32proc.c (setpgrp): Remove.
5015 (setsid, tcgetpgrp): New functions.
5017 Simplify by assuming __fpending.
5018 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
5019 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
5020 Do not assume that __fpending's result fits in int.
5022 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
5024 Remove EMACS_OUTQSIZE+sleep hack.
5025 * dispnew.c (update_frame_1): Remove hack for terminals slower
5026 than 2400 bps, which throttled Emacs by having it sleep.
5027 This code hasn't worked since at least 2007, when the multi-tty stuff
5028 was added, and anyway those old terminals are long dead.
5029 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
5030 without the dispnew.c change, as dispnew.c doesn't include systty.h.
5032 Fix data-loss with --version (Bug#9574).
5033 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
5034 as we can't assume that emacs_strerror is initialized, and strerror
5035 is good enough here.
5036 (main): Invoke atexit earlier, to catch earlier instances of
5037 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
5039 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
5041 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
5042 (keyDown): Remap keypad keys to X11 virtual key codes.
5044 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
5046 Fix data-loss with --batch (Bug#9574).
5047 * emacs.c: Include <close-stream.h>.
5048 (close_output_streams): New function.
5049 (main): Pass it to atexit, so that Emacs closes stdout and stderr
5050 and handles errors appropriately.
5051 (Fkill_emacs): Don't worry about flushing, as close_output_stream
5054 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
5055 The symptom is a diagnostic "GLib-WARNING **: In call to
5056 g_spawn_sync(), exit status of a child process was requested but
5057 SIGCHLD action was set to SIG_IGN and ECHILD was received by
5058 waitpid(), so exit status can't be returned." The diagnostic
5059 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
5060 The real bug is a race condition between Emacs and glib: Emacs
5061 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
5062 so that glib can't find it. Work around the bug by invoking
5063 waitpid only on subprocesses that Emacs itself creates.
5064 * process.c (create_process, record_child_status_change):
5065 Don't use special value -1 in pid field, as the caller now must
5066 know the pid rather than having the callee infer it.
5067 The inference was sometimes incorrect anyway, due to another race.
5068 (create_process): Set new 'alive' member if child is created.
5069 (process_status_retrieved): New function.
5070 (record_child_status_change): Use it.
5071 Accept negative 1st argument, which means to wait for the
5072 processes that Emacs already knows about. Move special-case code
5073 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
5074 processes that have already been waited for, by testing and
5075 clearing new 'alive' member.
5076 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
5077 now does this internally.
5078 (handle_child_signal): Let record_child_status_change do all
5079 the work, since we do not want to reap all exited child processes,
5080 only the child processes that Emacs itself created.
5081 * process.h (Lisp_Process): New boolean member 'alive'.
5083 Omit duplicate definitions no longer needed with gcc -g3.
5084 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
5085 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
5086 Define only as macros. There's no longer any need to also define
5087 these symbols as enums or as constants, since we now assume
5088 gcc -g3 when debugging.
5090 2012-11-03 Eli Zaretskii <eliz@gnu.org>
5092 * lisp.mk: Adjust comments to the fact that term/internal is now
5093 loaded from loadup.el.
5095 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
5096 (msdos_fatal_signal): New function.
5097 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to

5101 for GCC versions before 4.
5102 (emacs_raise): Define to call msdos_fatal_signal.
5104 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
5105 iterator when starting in the middle of a display or overlay
5108 2012-11-03 Chong Yidong <cyd@gnu.org>
5110 * process.c (wait_reading_process_output): Clean up the last
5113 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
5115 * process.c (wait_reading_process_output): Avoid a race condition
5116 with SIGIO delivery (Bug#11536).
5118 2012-11-03 Chong Yidong <cyd@gnu.org>
5120 * buffer.c (cursor_type): Untabify docstring.
5122 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5124 * frame.h (struct frame): Drop can_have_scroll_bars member
5125 which is meaningless for a long time. Adjust comments.
5126 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
5127 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
5129 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
5131 * window.c (decode_next_window_args): Update window arg after
5132 calling decode_live_window and so fix crash reported at
5133 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
5134 by Juanma Barranquero <lekktu@gmail.com>.
5135 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
5136 * font.c (Ffont_at): Likewise.
5138 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>

5149 (BACKTRACE_LIMIT_MAX): New macro.
5150 (w32_backtrace): New function.
5151 (emacs_abort): Use w32_backtrace when the user chooses not to
5152 attach a debugger. Update the text of the abort dialog.
5154 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5156 Window-related stuff cleanup here and there.
5157 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
5158 Use decode_any_window.
5159 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
5160 * xdisp.c (Fformat_mode_line): Likewise.
5161 * font.c (Ffont_at): Use decode_live_window.

5164 (decode_any_window): Remove static.
5165 * window.h (decode_any_window): Add prototype.
5166 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
5167 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
5170 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
5172 Remove pad from struct input_event.
5173 * termhooks.h (struct input_event): Remove padding field.
5175 * keyboard.c (event_to_kboard): Simplify because frame_or_window
5176 member is never cons for a long time. Adjust comment.
5177 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
5178 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
5179 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
5180 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
5182 2012-11-01 Eli Zaretskii <eliz@gnu.org>
5184 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
5186 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
5188 Fix crash when using Emacs as commit editor for git (Bug#12697).
5189 * callproc.c (setpgrp): Remove macro, as we now use setpgid
5190 and it is configured in conf_post.h.
5191 (Fcall_process): Don't invoke both setsid and setpgid; the former
5192 is enough, if it exists.
5193 * callproc.c (Fcall_process, child_setup):
5194 * process.c (create_process): Use setpgid.
5195 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
5197 * dispnew.c (init_display): Initialize the foreground group
5198 if we are running a tty display.
5199 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
5200 * lisp.h (init_foreground_group): New decl.
5201 * sysdep.c (inherited_pgroup): New static var.
5202 (init_foreground_group, tcsetpgrp_without_stopping)
5203 (narrow_foreground_group, widen_foreground_group): New functions.
5204 (init_sys_modes): Narrow foreground group.
5205 (reset_sys_modes): Widen foreground group.
5207 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
5209 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
5211 2012-10-31 Martin Rudalics <rudalics@gmx.at>
5213 * minibuf.c (read_minibuf): Restore current buffer since
5214 choose_minibuf_frame calling Fset_frame_selected_window may
5215 change it (Bug#12766).
5217 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
5219 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
5221 2012-10-30 Kenichi Handa <handa@gnu.org>
5223 * font.c (Ffont_at): If WINDOW is specified and it is not
5224 displaying the current buffer, signal an error.
5226 2012-10-29 Daniel Colascione <dancol@dancol.org>
5228 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
5229 In preparation for fixing bug#12739, move these functions from
5232 * coding.h, coding.c: ... to here, and compile them only when
5233 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
5234 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
5236 2012-10-28 Eli Zaretskii <eliz@gnu.org>
5238 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
5239 (timer_loop, getitimer, setitimer): Use it instead of
5240 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
5242 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
5245 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
5247 * nsterm.m (NO_APPDEFINED_DATA): New define.

5249 (last_appdefined_event): Remove.
5250 (ns_select): Initialize t from last_appdefined_event_data instead
5251 of [last_appdefined_event data1].
5252 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
5253 remove last_appdefined_event (Bug#12698).
5255 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
5257 * frame.c (x_set_font): Catch internal error.
5259 2012-10-27 Eli Zaretskii <eliz@gnu.org>
5261 Avoid overflow in w32 implementation of interval timers.
5262 When possible, for ITIMER_PROF count only times the main thread
5264 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
5265 'volatile ULONGLONG' types. All the other data which was
5266 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
5267 (GetThreadTimes_Proc): New typedef.
5268 (w32_get_timer_time): New function, returns a suitable time value
5270 (timer_loop): Enter critical section when accessing ULONGLONG
5271 values of the itimer_data struct, as these accesses are no longer
5272 atomic. Call 'w32_get_timer_time' instead of 'clock'.
5273 Remove unused variable.
5274 (init_timers): Initialize s_pfn_Get_Thread_Times.
5275 (start_timer_thread): Don't assign itimer->caller_thread here.
5276 (getitimer): Assign itimer->caller_thread here.

5282 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
5283 mouse movement events if the menu bar is active. This avoids
5284 producing a busy "hour-glass" cursor by Windows if the mouse
5285 pointer is positioned over a tooltip shown for some menu item.
5287 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
5289 Don't assume process IDs fit in int.
5290 * emacs.c (shut_down_emacs) [!DOS_NT]:
5291 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
5292 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
5293 Use pid_t, not int, to store process IDs, as 'int'
5294 is not wide enough on a few platforms (e.g., AIX and IRIX).
5296 2012-10-23 Kenichi Handa <handa@gnu.org>
5298 The following change is to make face-font-rescale-alist work
5299 correctly for non-ASCII fonts.
5301 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
5302 (font_open_for_lface): Handle Vface_font_rescale_alist.
5304 2012-10-23 Chong Yidong <cyd@gnu.org>
5306 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.

5317 2012-10-21 Glenn Morris <rgm@gnu.org>
5319 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
5321 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
5323 Port to OpenBSD 5.1.
5324 * frame.c (Fmouse_position, Fmouse_pixel_position):
5325 * xdisp.c (produce_stretch_glyph):
5326 Declare local vars only when they're needed.
5327 This is clearer and avoids a warning on OpenBSD about unused vars.
5328 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
5329 This is safer, and avoids OpenBSD warnings about unused vars.
5330 * keyboard.c (record_menu_key): Remove unnecessary decl.
5331 (poll_timer): Define only if POLL_FOR_INPUT is defined.
5332 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
5333 as our definition clashes with OpenBSD's.
5334 * xfaces.c (load_face_colors, check_lface_attrs)
5335 (get_lface_attributes_no_remap, get_lface_attributes)
5336 (lface_fully_specified_p, x_supports_face_attributes_p)
5337 (tty_supports_face_attributes_p, face_fontset, realize_face)
5338 (realize_x_face, realize_tty_face):
5339 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
5340 merely Lisp_Object *. This is more informative and avoids
5341 a warning on OpenBSD about accessing beyond an object's size.
5343 2012-10-20 Chong Yidong <cyd@gnu.org>
5345 * lread.c (Fload): Doc fix (Bug#12592).
5347 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
5349 * font.c (Ffont_at): Fix previous change.
5351 2012-10-19 Eli Zaretskii <eliz@gnu.org>
5353 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
5354 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

5367 FD_ISSET (Bug#12668).
5369 2012-10-18 Daniel Colascione <dancol@dancol.org>
5371 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
5372 (staticpro): If we run out of staticpro slots, die with an
5373 informative error instead of just calling emacs_abort.
5375 2012-10-18 Martin Rudalics <rudalics@gmx.at>
5377 Fix two flaws reported by Dmitry Antipov.
5378 * window.c (Ftemp_output_buffer_show): Remove.

5498 * fileio.c (Fwrite_region): Avoid race condition if a file is
5499 removed or renamed by some other process immediately after Emacs
5500 writes it but before Emacs stats it. Do not assume that stat (or
5502 * image.c (slurp_file): Resolve the file name with fopen + fstat

5534 a file exists. This avoids expensive system calls on MS-Windows.
5537 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
5539 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

5576 Use bool for booleans.
5577 * lread.c (safe_to_load_version): Rename from safe_to_load_p,

5581 2012-10-11 Dmitry Antipov <dmantipov@yandex.ru>
5583 * editfns.c (save_excursion_save): Use nil if mark points to nowhere.

5586 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
5588 * marker.c (cached_modiff): EMACS_INT, not int.
5590 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
5591 instead of having a wrong decl.

5629 (detect_input_pending_run_timers):
5630 * process.c (wait_reading_process_output):
5631 Use unsigned for counter where wraparound-on-overflow is desired,
5632 since unsigned is guaranteed to have that behavior and signed is not.
5633 (read_char): Use ptrdiff_t for string length.
5634 (get_input_pending): Remove first argument, since it was always
5635 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5636 and behave as if it had that value. Return new value of
5637 input_pending. All callers changed.
5638 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5639 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
5641 * keymap.c (push_key_description): Omit last arg, which was always 1.
5642 All callers changed.
5644 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
5646 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

5662 Don't include termopts.h.
5664 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
5666 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
5668 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5670 * commands.h (immediate_quit): Remove duplicate decl.
5672 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
5674 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

5677 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
5679 2012-10-09 Eli Zaretskii <eliz@gnu.org>
5681 * w32fns.c (w32_last_error): Change the return value to DWORD, to
5682 match what GetLastError returns. Explain why the function is
5685 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5686 'is_tooltip_frame', to avoid confusion with its global namesake.
5688 2012-10-08 Daniel Colascione <dancol@dancol.org>
5690 * xdisp.c (start_hourglass): Call w32_note_current_window when
5691 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5692 build that caused Emacs to display the hourglass cursor forever.
5694 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5695 which is broken under remote desktop, calculate the number of
5696 colors available for a display based on the display's number of
5697 planes and number of bits per pixel per plane. (bug#10397).
5699 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5701 * nsfont.m (Vfonts_in_cache): New variable.
5702 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5703 are used. Add cached fonts to Vfonts_in_cache.
5704 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5706 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5708 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5710 (FONT_H): Define after FRAME_H.
5711 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5712 Update dependencies.
5714 * w32term.c: Remove leftover declaration of keyboard_codepage.
5716 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5718 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5719 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5720 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5721 (GLOBAL_SOURCES): Add cygw32.c.
5722 ($(BLD)/unexw32.$(O)):
5724 ($(BLD)/w32console.$(O)):
5725 ($(BLD)/w32fns.$(O)):
5726 ($(BLD)/w32heap.$(O)):
5727 ($(BLD)/w32menu.$(O)):
5728 ($(BLD)/w32proc.$(O)): Add w32common.h.
5730 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5732 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5734 2012-10-08 Daniel Colascione <dancol@dancol.org>
5736 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5737 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5738 accidental message numbering hole. Change other messages to
5741 * w32select.h (HAVE_W32SELECT): Remove.
5743 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5744 w32common.h instead of w32heap.h.
5746 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
5747 (get_allocation_unit, get_processor_type, get_w32_major_version)
5748 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5749 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5750 (OS_NT, os_subtype, cache_system_info): Move declarations to
5753 * w32heap.c: Include w32common.h.
5754 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5755 (w32_minor_version, w32_build_number, w32_subtype):
5756 Remove duplicate definitions.
5758 * w32fns.c: Include w32common.h; include w32heap.h only in
5761 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5762 Use `report_file_error' instead of `error' in order to better
5763 inform users of what went wrong. Increase NTGUI_UNICODE file
5764 dialog box file name length to 32k, the maximum allowed by the NT
5767 * w32common.h: New file.
5768 (ROUND_UP, ROUND_DOWN, get_page_size)
5769 (get_allocation_unit, get_processor_type, get_w32_major_version)
5770 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5771 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5772 (OS_NT, os_subtype, cache_system_info): Move here.
5774 * unexw32.c, unexcw.c: Include w32common.h.
5776 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5777 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5778 to call syms_of_w32select.
5780 * cygw32.h: Remove obsolete EXFUN declarations.
5782 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5784 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5785 of w32inevt.o from SOME_MACHINE_OBJECTS.
5787 2012-10-08 Daniel Colascione <dancol@dancol.org>
5789 * image.c: Permanent fix for JPEG compilation issue --- limit
5790 jpeglib `boolean' redefinition to Cygwin builds.
5792 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5794 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5796 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5799 2012-10-08 Daniel Colascione <dancol@dancol.org>
5801 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5802 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5803 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5804 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5805 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5806 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5807 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5808 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5809 now a supported configuration.
5811 * Makefile.in: consolidate image variables into LIBIMAGE; add
5812 W32_OBJ and W32_LIBS. Compile new files.
5815 (_DebPrint) declare tracing facility for W32 debugging. We need
5816 to unify tracing later.
5818 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5819 unconditional use of W32 Unicode functions. Cygwin runs only on
5820 100% Unicode operating systems.
5822 * cygw32.c: New file. Define Cygwin-specific facilities.
5823 (Fcygwin_convert_path_to_windows)
5824 (Fcygwin_convert_path_from_windows): New user functions for
5825 accessing Cygwin path-munging routines.
5827 * cygw32.h: New file.
5828 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5829 UTF-16LE strings temporarily inside non-Lisp-visible string
5832 (w32_strerror): Just what it says on the tin.
5834 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5835 also run for Cygwin; both systems have the same problem with using
5836 GUI facilities in a forked child. Also call syms_of_cygw32,
5837 syms_of_w32select in correct places.
5839 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5840 needs fork-then-exec for daemon launching.
5842 * font.h: Include frame.h.
5844 * image.c: Use the image library cache machinery only when we're
5845 compiling for native WINDOWSNT; Cygwin can use shared libraries
5846 like any other Unixlike system.
5848 * keyboard.c: Clarify a comment regarding the input loop.
5850 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5851 functions directly instead of trying to detect at runtime that our
5852 host operating system supports them. We make this change for two
5853 reasons: Cygwin lacks support for the multibyte character
5854 conversion functions used by the legacy menu code, and Cygwin
5855 never needs to rely on non-Unicode APIs.
5857 * unexw32.c (hinst): Declare extern.
5859 * w32.c: Change header order;
5860 (w32_strerror): Move to w32fns.c because we need it for
5861 non-WINDOWSNT builds.
5863 * w32.h: Add #error macro to make sure we don't include w32.h for
5864 Cygwin builds. Remove w32select declarations.
5866 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5867 w32fns.c. w32console.c is WINDOWSNT-only.
5869 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5870 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5872 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5873 (w32_major_version, w32_minor_version, w32_build_number)
5874 (os_subtype, sound_type): Define here
5875 (w32_defined_color): Make color parameter const for consistency
5876 with other _defined_color functions.
5877 (w32_createwindow): Unconditionally call w32_init_class instead of
5878 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5879 through the code is complex and unnecessary because class
5880 registration is practically free.
5881 (w32_name_of_message): New EMACSDEBUG-only function.
5882 (Fset_message_beep): Move here
5883 (Fx_open_connection): Require that the display name for Windows be
5884 "w32" for consistency, emacsclient disambiguation, and maybe, one
5885 day, multi-window-system support.
5886 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5887 Cygwin files for W32 GUI facilities, since these clearly don't
5888 expect Cygwin names.
5889 (_DebPrint): Define.
5890 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5891 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5892 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5893 (w32_last_error): Remove.
5895 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5897 * w32heap.c (syspage_mask): Declare here.
5898 (cache_system_info): Remove.
5900 * w32inevt.c (faked_key): Define globally, not statically.
5901 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5902 (w32_console_toggle_lock_key): Move to w32fns.c.
5904 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5906 * w32proc.c (_DebPrint): Move to w32fns.c.
5907 * w32select.c: Include string.h, stdio.h for Cygwin.
5908 * w32select.h: New File.
5910 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5912 (w32_message_fd): New variable. Under Cygwin, holds the file
5913 descriptor the system used to tell us about pending thread
5916 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5917 that prevented compilation under non-WINDOWSNT systems.
5919 (w32_initialize): Open /dev/windows and assign it to
5920 w32_message_fd. Provide w32 feature.
5922 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5923 (WM_EMACS_INPUT_READY): add.
5924 (prepend_msg, w32_message_fd): Declare globally.
5927 (keyboard_handle): Use only when WINDOWSNT.
5928 (notify_msg_ready): New function. Posts a message to the main
5929 thread's message queue under CYGWIN, which wakes up the main
5930 thread from select(2) by making the /dev/windows file descriptor
5931 ready. Under WINDOWSNT, it sets an event the same way the old
5934 (post, prepend_msg): Actually call notify_msg_ready instead of
5935 setting the input event directly.
5937 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5939 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5940 but it still has blocs in it, don't return it to the system,
5941 instead of aborting. (Bug#12402)
5943 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5945 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5947 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5948 MAC_OS_X_VERSION_10_6.
5949 (syms_of_nsterm): Remove comment about Panther and above for

5953 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5955 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5956 MAC_OS_X_VERSION_10_4.
5958 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5959 MAC_OS_X_VERSION_10_2.
5961 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5963 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5964 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5966 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5967 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5968 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5969 Remove ns_in_resize check.
5970 (ns_clear_frame_area): Remove resize handle code.
5972 * nsfns.m (ns_in_resize): Remove.
5973 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5974 Remove ns_in_resize check.
5976 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5978 Improve sys_siglist detection.
5979 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5980 defined as a macro, as is done in Solaris.
5981 (sys_siglist_entries): New macro.
5982 (save_strsignal): Use it.
5983 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5984 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5986 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5988 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5989 fullscreen/Fullscreen.
5991 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5992 tobar_height is new.
5994 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5995 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5996 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5997 (windowDidResize:): Check for correct window if old style fullscreen.
5998 Capitalize word in comment. Remove incorrect comment.
5999 (initFrameFromEmacs:): tbar_height renamed tibar_height.
6000 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
6001 error in drawing background.
6002 (toggleFullScreen:): Remove comment. Rearrange calls.
6003 Set toolbar values to zero, save old height in tobar_height.
6004 Restore tool bar height when leaving fullscreen.
6005 (canBecomeMainWindow): New function.
6007 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
6009 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
6011 2012-10-05 Eli Zaretskii <eliz@gnu.org>
6013 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
6015 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
6016 that time stamps of directories could also be changed.
6017 Don't request the too broad GENERIC_WRITE, only the more restrictive
6018 FILE_WRITE_ATTRIBUTES access rights.
6020 * fileio.c (Fset_file_times): Special-case ignoring errors for
6021 directories only on MSDOS, not on MS-Windows.
6023 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
6025 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
6027 2012-10-04 Eli Zaretskii <eliz@gnu.org>
6029 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
6030 see whether CreateFile failed.
6032 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
6034 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
6035 to avoid similar races.
6036 * keyboard.c (pending_signals): Now bool, not int.
6038 Port timers to OpenBSD, plus check for timer failures.
6039 OpenBSD problem reported by Han Boetes.
6040 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
6042 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
6043 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
6044 like OpenBSD, which has timer_settime but does not declare it.
6045 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
6046 whether to use itimerspec-related primitives. All uses of
6047 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
6049 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
6051 * profiler.c (handle_profiler_signal): Fix a malloc race
6052 that caused Emacs to hang on Fedora 17 when profiling Lisp.
6054 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
6056 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
6058 2012-10-02 Eli Zaretskii <eliz@gnu.org>
6060 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
6061 consistent with the change in return value of 'safe_strsignal'.
6063 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>

6073 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
6074 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
6075 Now 'static', not 'static inline'.
6077 Count overruns when profiling; change units to ns.
6078 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
6079 Give extra weight to samples after overruns, to attempt to count
6080 the time more accurately.
6081 (setup_cpu_timer): Change sampling interval units from ms to ns, since
6082 the underlying primitives nominally do ns.
6083 (Fprofiler_cpu_start): Document the change. Mention that
6084 the sampling intervals are only approximate.
6086 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6088 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
6090 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
6091 case for the special 0 coding-system.
6093 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
6094 (Fmake_overlay): Remove redundant tests.
6095 (fix_start_end_in_overlays): Remove redundant recentering.
6097 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
6099 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
6100 Update dependencies.
6102 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6104 Fix a malloc race condition involving strsignal.
6105 A signal can arrive in the middle of a malloc, and Emacs's signal
6106 handler can invoke strsignal, which can invoke malloc, which is
6107 not portable. This race condition bug makes Emacs hang on GNU/Linux.
6108 Fix it by altering the signal handler so that it does not invoke
6110 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
6111 * process.c (status_message): Use const pointer, in case strsignal
6112 is #defined to safe_strsignal.
6113 * sysdep.c (sys_siglist, init_signals): Always define and
6114 initialize a substitute sys_siglist if the system does not define
6115 one, even if HAVE_STRSIGNAL.
6116 (safe_strsignal): Rename from strsignal. Always define,
6117 using sys_siglist. Return a const pointer.
6118 * syssignal.h (safe_strsignal): New decl.
6119 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
6121 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6123 * w32proc.c (timer_loop): Fix code that waits for timer
6124 expiration, to avoid high CPU usage.
6126 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
6128 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
6129 (sweep_weak_table): Remove redundant prototypes.
6131 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
6133 * emacs.c: Move the inclusion of TERM_HEADER after including
6134 windows.h on WINDOWSNT. This avoids compilation problems with
6137 2012-10-01 Eli Zaretskii <eliz@gnu.org>
6139 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
6140 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
6141 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
6142 as the previous version used 'void *'.
6144 * ralloc.c (ROUNDUP): Fix last change.
6145 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
6148 * w32proc.c <disable_itimers>: New static flag.
6149 (init_timers): Initialize it to zero, after creating the critical
6150 sections used by the timer threads.
6151 (term_timers): Set to 1 before deleting the critical sections.
6152 (getitimer, setitimer): If disable_itimers is non-zero, return an
6153 error indication without doing anything. Reported by Fabrice
6154 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
6155 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
6157 [!HAVE_SETITIMER]: Behave as the previous version that didn't
6160 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
6161 term_ntproc after all the other bookkeeping, to get timers working
6162 as long as possible.
6164 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
6166 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
6167 Suggested by Juri Linkov in
6168 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
6170 Prefer plain 'static' to 'static inline' (Bug#12541).
6171 With static functions, modern compilers inline pretty well by
6172 themselves; advice from programmers often hurts as much as it helps.
6173 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
6174 this change shrinks the text size of the Emacs executable by 1.1%
6175 without affecting CPU significantly in my benchmark.
6176 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

6260 not enough time to get that tested before the freeze today.
6261 * dired.c (directory_files_internal, Ffile_attributes):

6462 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
6463 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
6464 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
6466 (enum profiler_cpu_running): New enum.
6467 (profiler_cpu_running): Now of that enum type, not bool.
6468 All uses changed to store the new value.
6469 (handle_profiler_signal): Rename from sigprof_handler_1,
6470 for consistency with other handlers. Do not check whether
6471 cpu_log is a hash-table if garbage collecting, since it
6472 doesn't matter in that case.
6473 (deliver_profiler_signal): Rename from sigprof_handler,
6474 for consistency with other handlers.
6475 (setup_cpu_timer): New function, with much of what used to be in
6476 Fprofiler_cpu_start. Check for out-of-range argument.
6477 Prefer timer_settime if available, and prefer
6478 thread cputime clocks, then process cputime clocks, then
6479 monotonic clocks, to the old realtime clock. Use make_timeval
6480 to round more-correctly when falling back to setitimer.
6481 (Fprofiler_cpu_start): Use it.
6482 (Fprofiler_cpu_stop): Prefer timer_settime if available.
6483 Don't assume that passing NULL as the 2nd argument of setitimer
6484 is the same as passing a pointer to all-zero storage.
6485 Ignore SIGPROF afterwards.
6486 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
6487 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
6488 non-fatal signal handlers. Ignore SIGPROF on startup.
6489 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
6490 in profiler.c, since sysdep.c now uses it.
6492 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
6493 Suggested by Eli Zaretskii in
6494 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

6507 (Fbacktrace_frame): Adjust accordingly.
6509 2012-09-28 Glenn Morris <rgm@gnu.org>
6511 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
6512 (Frun_hook_with_args_until_failure): Doc fixes.
6514 2012-09-28 Eli Zaretskii <eliz@gnu.org>
6516 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
6517 Qautomatic_redisplay and change the symbol name. All users changed.

6544 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
6546 * character.h (MAYBE_UNIFY_CHAR): Remove.
6547 * charset.c, charset.h (maybe_unify_char): Now static.
6548 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
6549 Since this stuff is now private to charset.c, there's no need for
6550 a public macro and no need to inline by hand.

6581 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
6583 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
6585 Prefer POSIX timers if available.
6586 They avoid a race if the timer is too close to the current time.
6587 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
6588 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
6589 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
6591 2012-09-25 Eli Zaretskii <eliz@gnu.org>

6594 CHAR_STRING_ADVANCE.
6595 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
6596 STRING_CHAR_ADVANCE.

6612 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
6614 * w32.h (Vlibrary_cache): Do not declare.
6616 2012-09-25 Eli Zaretskii <eliz@gnu.org>
6618 * w32proc.c (sys_signal): Handle all signals defined by the
6619 MS-Windows runtime, not just SIGCHLD. Actually install the signal
6620 handlers for signals supported by Windows. Don't override
6621 term_ntproc as the handler for SIGABRT.
6622 (sigaction): Rewrite to call sys_signal instead of duplicating its
6624 (sys_kill): Improve commentary.
6626 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6627 consistency with a signature of a signal handler. All callers
6629 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6630 install term_ntproc as a signal handler for SIGABRT, as that
6631 should be done by the dumped Emacs.
6633 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6635 * w32select.c (term_w32select): Protect against repeated
6636 invocation by setting clipboard_owner to NULL after calling
6639 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
6640 and term_ntproc to their modified signatures.
6642 * character.c (char_string, string_char): Remove calls to
6643 MAYBE_UNIFY_CHAR. See the discussion starting at
6644 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
6647 2012-09-25 Chong Yidong <cyd@gnu.org>
6649 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
6651 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
6653 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
6654 when encountering an unknown bytecode.
6656 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
6658 image.c, indent.c: Use bool for booleans.
6659 * dispextern.h (struct image_type): Members valid_p, load, init
6660 now return bool, not int. All uses changed.
6661 * image.c: Omit unnecessary static decls.
6662 (x_create_bitmap_mask, x_build_heuristic_mask):
6663 Return void, not int, since callers don't care about the return value.

6698 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6700 Move pid_t related decls out of lisp.h.
6701 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6702 (interruptible_wait_for_termination):
6703 Move these decls from lisp.h to syswait.h, since they use pid_t.
6704 Needed on FreeBSD; see Herbert J. Skuhra in
6705 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6706 * callproc.c: Include syswait.h.

6726 Use bool for boolean.
6727 * gtkutil.c (xg_update_frame_menubar):

6752 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6754 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6755 fatal_error_backtrace.
6757 * w32proc.c (sys_kill): Undo last change: don't do anything when
6758 invoked to deliver SIGABRT to our own process. This is now
6759 handled by emacs_raise.
6761 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6763 * w32term.c (w32_read_socket): Remove leftover reference to
6764 interrupt_input_pending.
6766 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6768 Do not use SA_NODEFER.
6769 Problem reported by Dani Moncayo in
6770 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6772 * sysdep.c (emacs_abort): Do not reset signal handler.
6773 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6774 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6775 wanted even on POSIXish hosts, and it doesn't work on Windows.
6777 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6779 * xterm.c (x_term_init): Call fixup_locale before and after calling
6780 gtk_init (Bug#12392).
6782 2012-09-23 Chong Yidong <cyd@gnu.org>
6784 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6785 Vdynamic_library_alist.
6787 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6788 (Fgnutls_available_p): Caller changed.
6790 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6791 (Flibxml_parse_xml_region): Likewise.
6793 * dispextern.h (struct image_type): Remove arg from init function.
6795 * image.c (Finit_image_library, lookup_image_type)
6796 (define_image_type): Remove now-unneeded second arg.
6797 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6798 (init_tiff_functions, init_gif_functions, init_svg_functions):
6799 Arglist and w32_delayed_load calling convention changed.
6800 (gs_type): Remove init_gs_functions; there is no such function.
6801 (valid_image_p, make_image): Fix caller to lookup_image_type.
6803 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6805 Simplify and avoid signal-handling races (Bug#12471).
6807 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6808 Avoid recursive loop if there's a fatal error in the function itself.
6809 * atimer.c (pending_atimers):
6810 * blockinput.h: Don't include "atimer.h"; no longer needed.
6811 (interrupt_input_pending): Remove. All uses removed.
6812 pending_signals now counts both atimers and ordinary interrupts.
6813 This is less racy than having three separate pending-signal flags.
6814 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6816 Rename from their upper-case counterparts BLOCK_INPUT,
6817 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6818 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6819 This makes it easier to access volatile variables more accurately.
6820 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6821 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6822 that's more reliable if the code is buggy and sets
6823 interrupt_input_blocked to a negative value. All uses changed.
6824 * atimer.c (deliver_alarm_signal):
6825 Remove. No need to deliver this to the parent; any thread can
6826 handle this signal now. All uses replaced by underlying handler.
6827 * atimer.c (turn_on_atimers):
6828 * dispnew.c (handle_window_change_signal):
6829 * emacs.c (handle_danger_signal):
6830 * keyboard.c (kbd_buffer_get_event):
6831 Don't reestablish signal handler; not needed with sigaction.
6832 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6834 Rework to avoid unnecessary accesses to volatile variables.
6835 (UNBLOCK_INPUT_TO): Now a function.
6836 (totally_unblock_input, unblock_input): New decls.
6837 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6838 (init_data): Remove. Necessary stuff now done in init_signal.
6839 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6840 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6841 (fatal_error_code): Remove; no longer needed.
6842 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6843 it doesn't always backtrace. All uses changed. No need to reset
6844 signal to default, since sigaction and/or die does that for us now.
6845 Use emacs_raise (FOO), not kill (getpid (), FOO).
6846 (main): Check more-accurately whether we're dumping.
6847 Move fatal-error setup to sysdep.c
6848 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6849 * gtkutil.c (xg_get_file_name, xg_get_font):
6850 Remove no-longer-needed signal-mask manipulation.
6851 * keyboard.c, process.c (POLL_FOR_INPUT):
6852 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6853 * keyboard.c (read_avail_input): Remove.
6854 All uses replaced by gobble_input.
6855 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6856 (kbd_buffer_store_event_hold, gobble_input):
6857 (record_asynch_buffer_change) [USABLE_SIGIO]:
6858 (store_user_signal_events):
6859 No need to mess with signal mask.
6860 (gobble_input): If blocking input and there are terminals, simply
6861 set pending_signals to 1 and return. All hooks changed to not
6862 worry about whether input is blocked.
6863 (process_pending_signals): Clear pending_signals before processing
6864 them, in case a signal comes in while we're processing.
6865 By convention callers now test pending_signals before calling us.
6866 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6867 New functions, to support changes to blockinput.h.
6868 (handle_input_available_signal): Now extern.
6869 (reinvoke_input_signal): Remove. All uses replaced by
6871 (quit_count): Now volatile, since a signal handler uses it.
6872 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6873 All callers changed. Block SIGINT only if not already blocked.
6874 Clear sigmask reliably, even if Fsignal returns, which it can.
6875 Omit unnecessary accesses to volatile var.
6876 (quit_throw_to_read_char): No need to restore sigmask.
6877 * keyboard.c (gobble_input, handle_user_signal):
6878 * process.c (wait_reading_process_output):
6879 Call signal-handling code rather than killing ourselves.
6880 * lisp.h: Include <float.h>, for...
6881 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6882 (pending_signals): Now volatile.
6883 (syms_of_data): Now const if IEEE floating point.
6884 (handle_input_available_signal) [USABLE_SIGIO]:
6885 (terminate_due_to_signal, record_child_status_change): New decls.
6886 * process.c (create_process): Avoid disaster if memory is exhausted
6887 while we're processing a vfork, by tightening the critical section
6889 (send_process_frame, process_sent_to, handle_pipe_signal)
6890 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6892 (send_process): No need for setjmp/longjmp any more, since the
6893 SIGPIPE stuff is now gone. Instead, report an error if errno
6895 (record_child_status_change): Now extern. PID and W are now args.
6896 Return void, not bool. All callers changed.
6897 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6898 Remove. All uses removed. This bug should be fixed now in a
6900 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6901 and record the child status change directly. This avoids the
6902 need to futz with the signal mask.
6903 (process_fatal_action): Move here from emacs.c.
6904 (emacs_sigaction_flags): New function, containing
6905 much of what used to be in emacs_sigaction_init.
6906 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6907 caught by emacs, to make races less likely.
6908 (deliver_process_signal): Rename from handle_on_main_thread.
6910 (BACKTRACE_LIMIT_MAX): Now at top level.
6911 (thread_backtrace_buffer, threadback_backtrace_pointers):
6913 (deliver_thread_signal, deliver_fatal_thread_signal):
6914 New functions, for more-accurate delivery of thread-specific signals.
6915 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6916 (deliver_arith_signal): Handle in this thread, not
6917 in the main thread, since it's triggered by this thread.
6918 (maybe_fatal_sig): New function.
6919 (init_signals): New arg DUMPING so that we can be more accurate
6920 about whether we're dumping. Caller changed.
6921 Treat thread-specific signals differently from process-general signals.
6922 Block all signals while handling fatal error; that's safer.
6923 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6925 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6926 Ignore SIGPIPE unless batch.
6927 (emacs_backtrace): Output backtrace for the appropriate thread,
6928 which is not necessarily the main thread.
6929 * syssignal.h: Include <stdbool.h>.
6930 (emacs_raise): New macro.
6931 * xterm.c (x_connection_signal): Remove; no longer needed
6932 now that we use sigaction.
6933 (x_connection_closed): No need to mess with sigmask now.
6934 (x_initialize): No need to reset SIGPIPE handler here, since
6935 init_signals does this for us now.
6937 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6939 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6940 background rect may be larger (Bug#12245).
6942 2012-09-23 Chong Yidong <cyd@gnu.org>
6944 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6946 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6948 * .gdbinit: Just stop at fatal_error_backtrace.
6949 See Stefan Monnier's request in
6950 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6951 Remove no-longer-used query of system type.
6953 2012-09-22 Chong Yidong <cyd@gnu.org>
6955 * search.c (Freplace_match): Doc fix (Bug#12325).
6957 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6959 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6960 (Fline_end_position): Doc fix.
6962 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6964 2012-09-22 Chong Yidong <cyd@gnu.org>
6966 * dispextern.h (struct image_type): Add new slot, storing a type
6967 initialization function.
6969 * image.c (define_image_type): Call the image initializer function
6970 if it is defined. Arguments and return value changed.
6971 (valid_image_p, make_image): Callers changed.
6972 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6973 (gif_type, imagemagick_type, svg_type, gs_type):
6974 Add initialization functions.
6975 (Finit_image_library): Call lookup_image_type.
6976 (CHECK_LIB_AVAILABLE): Macro deleted.
6977 (lookup_image_type): Call define_image_type here, rather than via
6978 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6979 (syms_of_image): Move define_image_type calls for xbm_type and
6980 pbm_type to lookup_image_type.
6982 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6984 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6985 'idle_timers' from here ...
6986 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6987 lists, to avoid infloops when the timer does something stupid,
6988 like reinvoke itself with the same or smaller time-out.
6991 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6993 * window.c (Fsplit_window_internal): Handle only Qt value of
6994 Vwindow_combination_limit separately.
6995 (Qtemp_buffer_resize): New symbol.
6996 (Vwindow_combination_limit): New default value.
6999 2012-09-22 Eli Zaretskii <eliz@gnu.org>
7001 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
7002 the new overlay string. (Bug#10159)
7004 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
7006 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
7007 or that fprintf is async-signal-safe. POSIX doesn't require
7010 2012-09-22 Chong Yidong <cyd@gnu.org>
7012 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
7015 2012-09-22 Kenichi Handa <handa@gnu.org>
7017 * composite.c (composition_reseat_it): Handle the case that a
7018 grapheme cluster is not covered by a single font (Bug#12352).
7020 2012-09-21 Chong Yidong <cyd@gnu.org>
7022 * image.c (define_image_type): Avoid adding duplicate types to
7023 image_types (Bug#12463). Suggested by Jörg Walter.
7025 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7027 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
7028 (print_load_command_name): Add case LC_DATA_IN_CODE.
7029 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
7031 2012-09-21 Glenn Morris <rgm@gnu.org>
7033 * eval.c (Frun_hook_with_args_until_success)
7034 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
7036 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
7038 * fileio.c (Ffile_selinux_context): Only call freecon when
7039 lgetfilecon succeeded.
7040 (Fset_file_selinux_context): Likewise. (Bug#12444)
7042 2012-09-21 Eli Zaretskii <eliz@gnu.org>
7044 * xdisp.c (try_window_reusing_current_matrix): Under bidi
7045 reordering, locate the cursor by calling set_cursor_from_row; if
7046 that fails, clear the desired glyph matrix before returning a
7047 failure indication to the caller. Fixes leaving garbled display
7048 when fast scrolling with a down-key. (Bug#12403)
7049 (compute_stop_pos_backwards): Fix a typo that caused crashes while
7050 scrolling through multibyte text.
7052 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
7054 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
7055 calling mark_vectorlike since that's the one that marks the window.
7056 (mark_discard_killed_buffers): Mark the final cdr.
7057 * window.h (struct window): Move prev/next_buffers to the
7058 non-standard fields.
7059 * window.c (make_window): Initialize prev/next_buffers manually.
7061 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
7063 Omit unused arg EXPECTED from socket hooks.
7064 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
7065 * nsterm.m (ns_term_init):
7066 * termhooks.h (struct terminal.read_socket_hook):
7067 * w32inevt.c (w32_console_read_socket):
7068 * w32term.c (w32_read_socket):
7069 * xterm.c (XTread_socket):
7070 Omit unused arg EXPECTED. All callers changed.
7071 (store_user_signal_events): Return void, not int, since callers no
7072 longer care about the return value. All uses changed.
7074 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
7076 * w32gui.h (XParseGeometry): Do not declare.
7078 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
7080 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
7081 Ignore 'expected'. See Eli Zaretskii in
7082 <http://bugs.gnu.org/12471#8> (last line).
7084 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
7085 (XParseGeometry): Now static. Substitute extremal values for
7086 values that are out of range.
7088 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
7090 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
7092 * nsfns.m (XParseGeometry): Remove.
7093 (Fx_create_frame): Call x_set_offset to correctly interpret
7094 top_pos in geometry.
7096 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
7097 (Fx_parse_geometry): If there is a space in string, call
7098 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
7100 2012-09-17 Eli Zaretskii <eliz@gnu.org>
7102 * search.c (scan_buffer): Use character positions in calls to
7103 region_cache_forward and region_cache_backward, not byte
7104 positions. (Bug#12196)
7106 * w32term.c (w32_read_socket): Set pending_signals to 1, like
7107 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
7109 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
7110 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
7111 emacs_blocked_malloc, now deleted.
7113 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
7115 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
7116 The workaround was for improving performance on Solaris 2.4, but
7117 is getting in the way now. Emacs will still work if someone is
7118 still running Solaris 2.4 in a museum somewhere; Sun dropped
7119 support for Solaris 2.4 in 2003.
7120 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
7121 * process.c (create_process) [HAVE_WORKING_VFORK]:
7122 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
7123 since Emacs no longer uses vfork on that platform.
7125 2012-09-17 Glenn Morris <rgm@gnu.org>
7127 * emacs.c: Use COPYRIGHT.
7129 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
7131 Remove configure's --without-sync-input option (Bug#12450).
7132 When auditing signal-handling in preparation for cleaning it up,
7133 I found that SYNC_INPUT has race conditions and would be a real
7134 pain to fix. Since it's an undocumented and deprecated
7135 configure-time option, now seems like a good time to remove it.
7136 Also see <http://bugs.gnu.org/11080#16>.
7137 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
7138 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
7139 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7140 (malloc_hysteresis):
7141 (check_depth) [XMALLOC_OVERRUN_CHECK]:
7142 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
7143 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
7144 (dont_register_blocks, bytes_used_when_reconsidered)
7145 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
7146 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
7147 [!SYSTEM_MALLOC && !SYNC_INPUT]:
7148 Remove. All uses removed.
7149 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
7150 implementation, one that depends on whether the new macro
7151 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
7153 * atimer.c (run_timers, handle_alarm_signal):
7154 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
7155 (handle_async_input, process_pending_signals)
7156 (handle_input_available_signal, init_keyboard):
7157 * nsterm.m (ns_read_socket):
7158 * process.c (wait_reading_process_output):
7159 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
7160 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
7162 * xterm.c (XTread_socket):
7164 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
7165 * eval.c (handling_signal): Remove. All uses removed.
7166 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
7167 All uses replaced with the SYNC_INPUT version.
7168 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
7170 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7173 * font.c (Ffont_shape_gstring): Remove unused local.
7175 2012-09-16 Glenn Morris <rgm@gnu.org>
7177 * Makefile.in (clean): No longer run nextstep's clean.
7179 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
7181 (ns-app): Move here from ns.mk, and simplify.
7182 (clean): Simplify nextstep entry.
7183 * ns.mk: Remove file.
7185 2012-09-17 Kenichi Handa <handa@gnu.org>
7187 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
7188 not covert the last few charactes.
7190 2012-09-16 Kenichi Handa <handa@gnu.org>
7192 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
7193 here, but just check the validity of glyphs in the glyph-string.
7195 2012-09-16 Martin Rudalics <rudalics@gmx.at>
7197 * window.c (Fwindow_parameter, Fset_window_parameter):
7198 Accept any window as argument (Bug#12452).
7200 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
7202 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
7203 to ns_term_init to avoid memory leak.
7205 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
7206 explicit retain/release.
7207 (ns_term_init): Only allow one display. Initialize outerpool and
7210 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7212 Port _setjmp fix to POSIXish hosts as well as Microsoft.
7213 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
7214 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
7215 the Microsoft problem in a different way, by altering ../nt/config.nt.
7217 2012-09-15 Eli Zaretskii <eliz@gnu.org>
7232 * w16select.c: Remove inclusion of setjmp.h, as it is now included
7233 by lisp.h. This completes removal of setjmp.h inclusion
7234 erroneously announced in the previous commit. (Bug#12446)
7236 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
7239 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
7240 not defined as a macro. The latter happens on MS-Windows.
7243 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
7245 Port better to POSIX hosts lacking _setjmp (Bug#12446).
7246 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
7247 Some instances of '#include <setjmp.h>' removed, if the
7248 only reason for the instance was because "lisp.h" was included.
7249 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
7250 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
7251 and _longjmp with the new symbols. Emacs already uses _setjmp if
7252 available, so this change affects only POSIXish hosts that have
7253 sigsetjmp but not _setjmp, such as some versions of Solaris and
7254 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
7255 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
7256 (png_load_body) [HAVE_PNG]:
7257 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
7258 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
7259 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
7260 since PNG requires jmp_buf. This is the only exception to the
7261 general rule that we now use sys_setjmp and sys_longjmp.
7262 This exception is OK since this code does not change the signal
7263 mask or longjmp out of a signal handler.
7265 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
7267 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
7268 Include "syssignal.h", for 'main_thread'.
7270 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
7272 Avoid out-of-range marker position (Bug#12426).
7273 * insdel.c (replace_range, replace_range_2):
7274 Adjust markers before overlays, as suggested by comments.
7275 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
7276 Remove redundant check before calling offset_intervals.
7278 2012-09-14 Martin Rudalics <rudalics@gmx.at>
7280 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
7281 current buffer (Bug#12387).
7283 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
7285 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
7287 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7289 Use a more backwards-compatible timer format (Bug#12430).
7290 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
7291 vector element, not from the 4th, since PSECS is now at the end.
7292 (Fcurrent_idle_time): Doc fix.
7294 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
7296 Function to mark objects and remove killed buffers at once.
7297 * alloc.c (discard_killed_buffers): Rename to ...
7298 (mark_discard_killed buffers) ... new name. Add marking
7299 of remaining objects. Fix comment. Adjust users.
7300 (mark_object): Do not touch frame buffer lists here.
7301 * frame.c (delete_frame): Reset frame buffer lists here.
7303 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
7305 Better workaround for GNOME bug when --enable-gcc-warnings.
7306 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
7307 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
7308 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
7310 Simplify SIGIO usage (Bug#12408).
7311 The code that dealt with SIGIO was crufty and confusing, e.g., it
7312 played tricks like "#undef SIGIO" but these tricks were not used
7313 consistently. Simplify mostly by not #undeffing standard symbols,
7314 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
7315 or not as we please) rather than "defined SIGIO" (standard symbol
7316 that we probably shouldn't #undef).
7317 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
7318 Modules that need it can include it.
7319 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
7320 * dispextern.h (ignore_sigio): New decl.
7321 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
7322 unconditionally, since it's now a no-op if !USABLE_SIGIO.
7323 * emacs.c (shut_down_emacs):
7324 * keyboard.c (kbd_buffer_store_event_hold):
7325 Use ignore_sigio rather than invoking 'signal' directly.
7326 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
7328 (FIONREAD, SIGIO): Do not #undef.
7329 (tty_read_avail_input): Use #error rather than a syntax error.
7330 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
7331 for I_PIPE, used by SETUP_SLAVE_PTY.
7332 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
7333 * sysdep.c (croak): Remove; no longer needed. This bit of
7334 temporary code, with Fred N. Fish's comment that it's temporary,
7335 has been in Emacs since at least 1992!
7336 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
7337 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
7338 * syssignal.h (croak): Remove decl.
7339 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
7340 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
7341 now that we're termios-only.
7342 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
7343 * term.c (dissociate_if_controlling_tty): Use #error rather than
7346 Work around GCC and GNOME bugs when --enable-gcc-warnings.
7347 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
7348 to work around GNOME bug 683906.
7349 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
7350 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
7351 This works around GCC bug 54561.
7353 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7355 More fixes for 'volatile' and setjmp/longjmp.
7356 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
7357 * image.c (struct png_load_context) [HAVE_PNG]: New type.
7358 (png_load_body) [HAVE_PNG]:
7359 (jpeg_load_body) [HAVE_JPEG]:
7360 New function, with most of the old parent function's body.
7361 (png_load) [HAVE_PNG]:
7362 (jpeg_load) [HAVE_JPEG]:
7363 Invoke the new function, to avoid longjmp munging our locals.
7364 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
7365 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
7366 longjmp is passed 2, as the C standard doesn't guarantee this.
7367 Instead, store the failure code into mgr->failure_code.
7369 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7371 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
7372 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
7373 (syms_of_keyboard): Remove support for unread-command-char.
7375 2012-09-12 Eli Zaretskii <eliz@gnu.org>
7377 * w32proc.c (sys_kill): If PID is our process ID and the signal is
7378 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
7379 violation. (Bug#12426)
7381 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
7383 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
7385 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
7387 * eval.c: Add `inhibit-debugger'.
7388 (Qinhibit_debugger): New symbol.
7389 (call_debugger): Bind it instead of Qdebug_on_error.
7390 (maybe_call_debugger): Test Vinhibit_debugger.
7391 (syms_of_eval): Define inhibit-debugger.
7392 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
7393 (syms_of_xdisp): Remove inhibit-debug-on-message.
7395 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7397 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
7398 If a nonvolatile local variable is written before a _longjmp to
7399 the frame containing the variable, and is read after the _longjmp,
7400 the value read is indeterminate. Some local variables of type
7401 'struct handler' and 'struct catchtag' are used in this way, so
7402 mark each of their slots as volatile if the slot can be set before
7403 _longjmp and read afterwards.
7404 * lisp.h (struct handler): var and chosen_clause are now volatile.
7405 (struct catchtag): val, next, and pdlcount are now volatile.
7407 * bidi.c (bidi_push_it, bidi_pop_it):
7408 * fns.c (copy_hash_table):
7409 * image.c (define_image_type):
7410 * keyboard.c (kbd_buffer_store_event_hold):
7411 * process.c (Fprocess_send_eof):
7412 * xfaces.c (x_create_gc) [HAVE_NS]:
7413 * xgselect.c (xg_select):
7414 Prefer assignment to memcpy when either will do.
7416 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
7417 Use pointer-to-a-pointer to simplify and avoid a NILP check each
7418 time an item is removed. No need to mark this function 'inline';
7419 the compiler knows better than we do.
7421 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
7423 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
7424 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
7425 to change_frame_size (Bug#12388).
7426 (windowDidResize:): Pass YES to updateFrameSize.
7428 * nsterm.h: Add delay parameter to updateFrameSize.
7430 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7432 Discard killed buffers from deleted window and frame objects.
7433 This reduces an amount of references to killed buffers and
7434 helps GC to reclaim them faster.
7435 * alloc.c (discard_killed_buffers): New function.
7436 (mark_object): Use it for deleted windows and frames.
7437 (mark_object): If symbol's value is set up for a killed buffer
7438 or deleted frame, restore its global binding.
7439 * data.c (swap_in_global_binding): Add GC notice.
7440 (swap_in_symval_forwarding): Use convenient set_blv_where.
7441 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
7442 * window.h: ... to here.
7444 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7446 Convenient macro to check whether the buffer is live.
7447 * buffer.h (BUFFER_LIVE_P): New macro.
7448 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
7449 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
7451 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7453 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
7454 composition cases (Bug#12364).
7456 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
7457 overhang of succeeding glyphs overlapping box cursor.
7459 * w32term.c (x_draw_glyph_string): Likewise.
7461 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7463 Simplify, document, and port floating-point (Bug#12381).
7464 The porting part of this patch fixes bugs on non-IEEE platforms
7465 with frexp, ldexp, logb.
7466 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
7468 * floatfns.c: Simplify discussion of functions that Emacs doesn't
7469 support, by removing commented-out code and briefly listing the
7470 C89 functions excluded. The commented-out stuff was confusing
7471 maintenance, e.g., we thought we needed cbrt but it was commented out.
7472 (logb): Remove decl; no longer needed.
7473 (isfinite): New macro, if not already supplied.
7474 (isnan): Don't replace any existing macro.
7475 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
7476 are present on all C89 platforms.
7477 (Ffrexp): Do not special-case zero, as frexp does the right thing
7479 (Flogb): Do not use logb, as it doesn't have the desired meaning
7480 on hosts that use non-base-2 floating point. Instead, stick with
7481 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
7482 frexp, to avoid getting an unspecified result.
7484 * xdisp.c (Qinhibit_debug_on_message): Now static.
7486 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
7488 * nsterm.m (ns_update_begin): Set clip path to whole view by using
7489 NSBezierPath (Bug#12131).
7491 2012-09-10 Chong Yidong <cyd@gnu.org>
7493 * fns.c (Fdelq, Fdelete): Doc fix.
7495 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
7497 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
7498 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
7500 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
7502 * lisp.h (make_lisp_ptr): New macro to replace XSET.
7503 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
7506 2012-09-09 Eli Zaretskii <eliz@gnu.org>
7508 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
7509 left fringe if the window has a left margin. This avoids leaving
7510 traces of the cursor because its leftmost pixel is not drawn over.
7512 * dispnew.c (update_window_line): When the left margin area of a
7513 screen line is updated, set the redraw_fringe_bitmaps_p flag of
7514 that screen line. (Bug#12277)
7516 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
7518 Assume C89 or later for math functions (Bug#12381).
7519 This simplifies the code, and makes it a bit smaller and faster,
7520 and (most important) makes it easier to clean up signal handling
7521 since we can stop worring about floating-point exceptions in
7522 library code. That was a problem before C89, but the problem
7523 went away many years ago on all practical Emacs targets.
7524 * data.c, image.c, lread.c, print.c:
7525 Don't include <math.h>; no longer needed.
7526 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
7527 might be autoconfigured, as that never happens.
7529 * doprnt.c (DBL_MAX_10_EXP):
7530 * print.c (DBL_DIG):
7531 Remove. C89 or later always defines these.
7532 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
7533 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
7534 (arith_error, domain_error, domain_error2):
7535 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
7536 no longer needed -- we simply return what C returns. All uses removed.
7537 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
7539 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
7540 Remove. All uses expanded, as these macros are no longer used
7541 more than once and are now more trouble than they're worth.
7542 (Ftan): Use tan, not sin / cos.
7543 (Flogb): Assume C89 frexp.
7544 (fmod_float): Assume C89 fmod.
7545 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
7546 (init_floatfns): Remove. All uses removed.
7548 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7550 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
7551 compositeToPoint for OSX < 10.6 (Bug#12390).
7553 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
7555 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
7556 This produces more-accurate results.
7558 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7560 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
7561 changes (Bug#12088).
7563 2012-09-08 Chong Yidong <cyd@gnu.org>
7565 * syntax.c (Fstring_to_syntax): Doc fix.
7567 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7569 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
7570 in the internal border.
7571 (x_set_window_size): Remove static variables and their usage.
7572 (ns_redraw_scroll_bars): Fix NSTRACE arg.
7573 (ns_after_update_window_line, ns_draw_fringe_bitmap):
7574 Remove fringe/internal border adjustment (Bug#11052).
7575 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
7576 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
7577 (ns_fix_rect_ibw): Remove.
7578 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
7579 (ns_dumpglyphs_box_or_relief): Ditto.
7580 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
7582 (ns_dumpglyphs_image): Ditto.
7583 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
7585 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
7586 their usage. Add fringe_extended_p and its use as in other terms.
7587 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
7588 scroll bar was removed.
7589 (updateFrameSize): New function.
7590 (windowDidResize): Move code to updateFrameSize and call it.
7592 * nsterm.h (EmacsView): Add updateFrameSize.
7594 2012-09-07 Chong Yidong <cyd@gnu.org>
7596 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
7598 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
7600 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7602 More signal-handler cleanup (Bug#12327).
7603 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
7604 Problem introduced when merging patches. Noted by Eli Zaretskii in
7605 <http://bugs.gnu.org/12327#67>.
7606 * floatfns.c: Comment fix.
7607 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
7608 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
7609 and anyway the declaration is harmless even if SIGDANGER is not defined.
7610 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
7611 defined BROKEN_FIONREAD). systty.h formerly did this, but other
7612 source files not surprisingly expected syssignal.h to define, or
7613 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7614 Include <sys/ioctl.h>, for FIONREAD.
7615 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7616 This eliminates a problem whereby other files mysteriously had
7617 to include "syssignal.h" before including "systty.h" if they
7618 wanted to use "#ifdef SIGIO".
7620 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7622 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7624 * w32.c (sigemptyset): Empty the set.
7625 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7627 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7629 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7631 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7632 (mark_object): Likewise for frame objects.
7634 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7636 * syssignal.h (handle_on_main_thread): Always declare,
7637 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7638 This ports to platforms without HAVE_PTHREAD.
7640 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7642 Signal-handler cleanup (Bug#12327).
7643 Emacs's signal handlers were written in the old 4.2BSD style with
7644 sigblock and sigmask and so forth, and this led to some
7645 inefficiencies and confusion. Rewrite these to use
7646 pthread_sigmask etc. without copying signal sets around. Also,
7647 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7648 'signal', and instead use functions that do not attempt to take
7649 over the system name space. This patch causes Emacs's text
7650 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7651 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7652 Do not include <signal.h> or "syssignal.h", as these
7653 modules do not use signals.
7654 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7655 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7656 Do not include <signal.h>, as "syssignal.h" does that for us now.
7657 * atimer.c (sigmask_atimers): New function.
7658 (block_atimers, unblock_atimers): New functions,
7659 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7661 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7662 no longer needed here.
7663 * emacs.c (main): Inspect existing signal handler with sigaction,
7664 so that there's no need to block and unblock SIGHUP.
7665 * sysdep.c (struct save_signal): New member 'action', replacing
7666 old member 'handler'.
7667 (save_signal_handlers, restore_signal_handlers):
7668 Use sigaction instead of 'signal' to save and restore.
7669 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7670 New function. All users of 'signal' modified to use set_sighandler
7671 if they're writeonly, and to use sys_signal if they're read+write.
7672 (emacs_sigaction_init, forwarded_signal): New functions.
7673 (sys_signal): Remove. All uses replaced by calls to sigaction
7674 and emacs_sigaction_init, or by direct calls to 'signal'.
7675 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7676 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7677 all uses replaced by pthread_sigmask etc. calls.
7678 * syssignal.h: Include <signal.h>.
7679 (emacs_sigaction_init, forwarded_signal): New decls.
7680 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7681 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7682 (sigmask, sys_sigmask): Remove; no longer needed.
7683 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7684 (sigblock, sigunblock, sigfree):
7685 (sigsetmask) [!defined sigsetmask]:
7686 Remove. All uses replaced by pthread_sigmask.
7687 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7688 no longer need to be replaced, and its typical old uses
7689 are now done via emacs_sigaction_init and sigaction.
7690 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7691 (sys_sigdel): Remove; unused.
7692 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7694 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7696 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7697 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7699 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7701 Explicitly mark buffer_defaults and buffer_local_symbols.
7702 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7703 mark_local_symbols here.
7704 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7705 since special buffers aren't marked here any more.
7706 (allocate_buffer): Chain new buffer with all_buffers here...
7707 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7709 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7710 (syms_of_buffer): Remove staticpro of the above.
7711 (init_buffer_once): Set names for buffer_defaults and
7712 buffer_local_symbols.
7714 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7716 Use bool for booleans in font-related modules.
7717 * font.c (font_intern_prop, font_style_to_value)
7718 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7719 (generate_otf_features, font_check_otf_features, font_check_otf)
7720 (font_match_p, font_list_entities, font_at):
7721 * fontset.c (fontset_id_valid_p, reorder_font_vector
7722 (fontset_find_font, Fset_fontset_font)
7723 (face_suitable_for_char_p) [0]:
7724 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7725 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7726 (m17n_flt_initialized, ftfont_shape_by_flt):
7727 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7728 * nsfont.m (nsfont_draw):
7729 * w32font.c (w32font_draw):
7730 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7731 Use bool for booleans.
7732 * font.h: Adjust to above API changes.
7733 (struct font, struct font_driver, struct font_driver_list):
7734 Use bool for booleans.
7735 (struct font): Remove useless member encoding_type.
7737 * fontset.c, xftfont.c: Omit unnecessary static decls.
7739 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7741 * alloc.c (mark_object): Revert window marking code
7742 since it's unsafe for the Fset_window_configuration.
7744 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7746 Fix race conditions with signal handlers and errno (Bug#12327).
7747 Be more systematic about preserving errno whenever a signal
7748 handler returns, even if it's not in the main thread. Do this by
7749 renaming signal handlers to distinguish between signal delivery
7750 and signal handling. All uses changed.
7751 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7752 * data.c (deliver_arith_signal): Rename from arith_error.
7753 * dispnew.c (deliver_window_change_signal): Rename from
7754 window_change_signal.
7755 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7756 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7757 * keyboard.c (deliver_input_available_signal): Rename from
7758 input_available_signal.
7759 (deliver_user_signal): Rename from handle_user_signal.
7760 (deliver_interrupt_signal): Rename from interrupt_signal.
7761 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7762 (deliver_child_signal): Rename from sigchld_handler.
7763 * atimer.c (handle_alarm_signal):
7764 * data.c (handle_arith_signal):
7765 * dispnew.c (handle_window_change_signal):
7766 * emacs.c (handle_fatal_signal, handle_danger_signal):
7767 * keyboard.c (handle_input_available_signal):
7768 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7769 * process.c (handle_pipe_signal, handle_child_signal):
7770 New functions, with the actual signal-handling code taken from the
7771 original respective signal handlers, sans the sporadic attempts to
7772 preserve errno, since that's now done by handle_on_main_thread.
7773 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7774 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7775 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7777 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7778 Move initialization of main_thread to sysdep.c's init_signals.
7779 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7780 our usage, and simplifies the mainline code.
7781 (record_child_status_change): New static function, as a helper
7782 for handle_child_signal, and with most of the old child handler's
7784 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7785 (handle_child_signal): Use the above.
7786 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7787 Moved here from emacs.c.
7788 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7789 code moved here from emacs.c's main function.
7790 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7791 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7792 This lets callers save and restore errno properly.
7794 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7796 Remove redundant or unused things here and there.
7797 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7798 * conf_post.h (RE_TRANSLATE): Use char_table_translate.

7800 * frame.h (struct terminal, struct font_driver_list):
7801 Remove redundant declarations.
7802 * window.h (Qleft, Qright): Likewise.
7804 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7806 Do not mark objects from deleted buffers, windows and frames.
7807 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7808 (mark_object): Likewise for windows and frames.
7810 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7812 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7813 buffer_defaults and buffer_local_symbols as valid objects.
7814 Return special value to denote them.
7816 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7818 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7819 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7820 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7821 (file_name_absolute_p, Fsubstitute_in_file_name):
7822 (check_executable, check_writable, Ffile_accessible_directory_p)
7823 (Fset_file_selinux_context, Fdefault_file_modes)
7824 (Finsert_file_contents, choose_write_coding_system)
7825 (Fwrite_region, build_annotations, a_write, e_write)
7827 * filelock.c (boot_time_initialized, get_boot_time)
7828 (get_boot_time_1, lock_file_1, within_one_second):
7829 * floatfns.c (in_float):
7830 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7831 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7832 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7833 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7834 * window.c (compare_window_configurations):
7835 Use bool for booleans.
7836 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7837 (Fdefault_file_modes): Now mode_t, not int, for modes.
7838 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7839 (internal_delete_file): Now returns void, not a (boolean) int,
7840 since nobody was looking at the return value.
7841 * lisp.h, window.h: Adjust to above API changes.
7843 * xdisp.c (set_message): Simplify and reindent last change.
7845 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7847 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7849 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7851 * eval.c (call_debugger): Make the function non-static so that we
7852 can call it from set_message.
7854 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7855 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7857 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7859 Give more-useful info on a fatal error (Bug#12328).
7860 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7861 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7862 of doing the work ourselves.
7863 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7864 do most of the work.
7865 (fatal_error_backtrace): New function, taken from the guts
7866 of the old fatal_error_signal, but with a new option to output
7868 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7869 info about the signal than just its number.
7870 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7871 * sysdep.c: Include <execinfo.h>
7872 (emacs_backtrace): New function, taken partly from the previous
7873 code of the 'die' function.
7874 (emacs_abort): Call fatal_error_backtrace rather than abort.
7876 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7878 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7879 eager (load-time) macro-expansion.
7880 * lisp.mk (lisp): Add macroexp.
7882 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7884 Simplify redefinition of 'abort' (Bug#12316).
7885 Do not try to redefine the 'abort' function. Instead, redo
7886 the code so that it calls 'emacs_abort' rather than 'abort'.
7887 This removes the need for the NO_ABORT configure-time macro
7888 and makes it easier to change the abort code to do a backtrace.
7889 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7890 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7891 Remove; sysdep.c's emacs_abort now takes its place.
7892 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7893 'abort' changed to use 'emacs_abort'.
7894 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7895 (abort) [!defined abort]: Rename to ...
7896 (emacs_abort): ... new name.
7897 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7898 the place of the old 'abort' in emacs.c.
7899 * w32.c, w32fns.c (abort): Do not #undef.
7900 * w32.c (emacs_abort): Rename from w32_abort.
7902 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7904 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7905 offsets[j].dv, since the y axis of the screen coordinates points
7906 down, while the y axis of the font definition coordinates points
7907 up. This fixes display of Arabic diacritics such as KASRA and
7908 KASRATAN. (Bug#11860)
7910 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7912 Be more systematic about _setjmp vs setjmp.
7913 * alloc.c (test_setjmp, mark_stack):
7914 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7915 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7916 (png_load, my_error_exit, jpeg_load):
7917 * process.c (send_process_trap, send_process):
7918 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7919 The underscored versions are up to 30x faster on some hosts.
7920 Formerly, the code used setjmp+longjmp sometimes and
7921 _setjmp+_longjmp at other times, with no particular reason to
7922 prefer setjmp+longjmp.
7924 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7926 Fix minor problem found by static checking.
7927 * buffer.c (Fdelete_all_overlays): Return nil.
7929 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7931 * buffer.c (Fdelete_all_overlays): New function.
7933 2012-09-03 Chong Yidong <cyd@gnu.org>
7935 * gtkutil.c: Add extern decl for Qxft.
7937 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

7951 All callers changed.
7952 * eval.c (interactive_p): Omit always-true boolean argument
7953 EXCLUDE_SUBRS_P. All callers changed.
7954 * dispextern.h, lisp.h: Reflect above API changes.
7955 * firstfile.c (dummy): Use the address of 'main', whose signature
7956 won't change, instead of the address of 'initialize', whose
7957 signature just changed from int to bool.
7958 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7959 * msdos.c (fatal_error_in_progress): ... from here.
7960 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7962 (redisplay_internal, unwind_redisplay): Simply clear
7963 REDISPLAYING_P when unwinding, instead of saving its previous,
7964 always-false value and then restoring it.
7966 Clean up some extern decls.
7967 Mostly, this hoists extern decls out of .c files and into .h files.
7968 That way, we're more likely to catch errors if the interfaces change.
7969 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7970 declare xg_mark_data.
7971 * dispextern.h (x_frame_parm_handlers):
7973 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
7974 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)

7987 * widget.c (free_frame_faces):
7988 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
7989 * xfont.c (x_clear_errors):
7990 * xterm.c (x_frame_parm_handlers):
7991 Remove now-redundant extern decls.
7992 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7993 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7995 * xfaces.c: Remove unnecessary static decls.
7996 * xterm.c (updating_frame): Remove decl of nonexistent object.
7998 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7999 when building globals.h, as the objects that are not built on
8000 this host are not needed to compile C files on this host.
8002 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
8004 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

8017 (format_time_string, general_insert_function)
8018 (make_buffer_string, make_buffer_string_both)
8019 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
8020 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)
8021 (copy_text, insert_1, insert_1_both, insert_from_string)

8030 (get_property_and_range, compare_string_intervals)
8031 (set_intervals_multibyte_1, set_intervals_multibyte):
8032 * keyboard.c (decode_timer):
8033 Use bool for boolean.
8034 * intervals.h, lisp.h, systime.h: Reflect above API changes.
8035 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
8037 2012-09-02 Chong Yidong <cyd@gnu.org>
8039 * keymap.c (push_key_description): Print M-TAB as C-M-i
8042 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
8044 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
8045 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

8050 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
8052 2012-09-01 Eli Zaretskii <eliz@gnu.org>
8054 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
8055 more than one grapheme cluster passed to the shaper: compute the
8056 offset adjustment values separately for each cluster. (Bug#11860)
8058 * image.c: Restore mistakenly removed inclusion of w32.h. Without
8059 it, GCC doesn't see prototypes of w32_delayed_load, and complains
8060 about implicit conversions from integer to pointer.
8062 2012-09-01 Daniel Colascione <dancol@dancol.org>
8064 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
8065 system used too early.
8067 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
8069 Better seed support for (random).
8070 * emacs.c (main): Call init_random.

8098 * process.c: Include TERM_HEADER instead of listing all possible
8099 window-system headers.
8101 * nsterm.h: Remove declarations now in frame.h.
8102 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
8104 * menu.c: Include TERM_HEADER instead of listing all possible
8105 window-system headers.
8107 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
8110 * keyboard.c: Include TERM_HEADER instead of listing all possible
8111 window-system headers.
8113 * image.c: Include TERM_HEADER instead of listing all possible
8114 window-system headers. Declare Vlibrary_cache when compiling for
8117 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
8118 window system declarations.
8120 * frame.h: Move common functions here: set_frame_menubar,
8121 x_set_window_size, x_sync, x_get_focus_frame,
8122 x_set_mouse_position, x_set_mouse_pixel_position,
8123 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

8144 the current window system; include in list of objects to link into
8147 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8149 Remove mark_ttys function and fix tty_display_info initialization.
8150 * lisp.h (mark_ttys): Remove prototype.
8151 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
8152 to mark_ttys because all possible values of 'top_frame' slot are
8153 the frames which are reachable from Vframe_list.
8154 * term.c (mark_ttys): Remove.
8155 (init_tty): Safely initialize 'top_frame' slot with Qnil.
8157 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8159 Change struct frame bitfields from unsigned char to unsigned.
8160 * frame.h (struct frame): Change type of 'display_preempted',

8162 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
8163 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
8164 bitfields from unsigned char to unsigned.
8166 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
8168 Remove unused member of struct x_output and struct w32_output.

8172 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
8174 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
8175 does not become zero (Bug#12234).
8177 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
8179 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
8180 for GCC 4.7.1 x86-64.
8182 2012-08-30 Glenn Morris <rgm@gnu.org>
8184 * lread.c (init_lread): For out-of-tree builds, only add the
8185 source directory's site-lisp dir to the load-path if it exists,
8186 consistent with in-tree builds. (Bug#12302)
8188 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
8190 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
8191 button_values to NULL. Call setStykeMask so dialogs get a close button.
8192 (windowShouldClose:): Set window_closed.
8193 (dealloc): New member, free button_values.
8194 (process_dialog:): Make member function. Remove window argument,
8195 replace window with self. Count buttons and allocate and store values
8197 (addButton:value:row:): value is int with the name tag. Call setTag
8198 with tag. Remove return self, declare return value as void.
8199 (addString:row:): Remove return self, declare return value as void.
8200 (addSplit): Remove return self, declare return value as void.
8201 (clicked:): Remove return self, declare return value as void.
8202 Set dialog_return to button_values[seltag]. Code formatting change.
8203 (initFromContents:isQuestion:): Adjust call to process_dialog.
8204 Code formatting change.
8205 (timeout_handler:): Set timer_fired to YES.
8206 (runDialogAt:): Set timer_fired to NO.
8207 Handle click on close button as quit.
8209 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
8210 Add window_closed and button_values. Add void as return value for
8211 add(Button|String|Split). addButton takes int instead of Lisp_Object.
8212 Add process_dialog as new member.
8214 2012-08-28 Eli Zaretskii <eliz@gnu.org>
8216 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
8217 is not one of the heaps we manage. (Bug#12242)
8219 2012-08-28 Glenn Morris <rgm@gnu.org>
8221 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
8223 2012-08-28 Martin Rudalics <rudalics@gmx.at>

8233 if the buffer is dead.
8234 (Fother_buffer, other_buffer_safely): Remove redundant
8237 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
8239 Always use set_buffer_if_live to restore original buffer at unwind.
8240 * buffer.h (record_unwind_current_buffer): New function.

8248 Fix usage of set_buffer_internal.
8249 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
8250 * buffer.c (set_buffer_if_live): Use set_buffer_internal.

8277 (change_frame_size_1, sit_for):
8278 Use bool for boolean.
8279 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
8280 and remove last int (actually boolean) argument, which was always 0.
8281 All callers changed.
8282 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
8283 * dispextern.h (struct composition_it): Use bool for boolean.
8284 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
8285 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
8286 * dired.c (file_name_completion):
8287 Use bool for boolean. (This was missed in an earlier change.)
8289 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8291 * window.c (Fset_window_configuration): Revert first part of
8294 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
8296 * nsterm.h (NSPanel): New class variable dialog_return.
8298 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
8299 Initialize dialog_return.
8300 (windowShouldClose:): Use stop instead of stopModalWithCode.
8301 (clicked:): Ditto, and also set dialog_return (Bug#12258).
8302 (timeout_handler:): Use stop instead of abortModal. Send a dummy
8304 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
8307 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

8349 Use bool for booleans.
8350 * coding.h, lisp.h: Reflect above API changes.
8351 * coding.c: Remove unnecessary static function decls.
8352 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
8353 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
8354 not a boolean 'int', since callers never look at the return value.
8355 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
8356 * coding.h (decoding_buffer_size, encoding_buffer_size)
8357 (emacs_mule_string_char): Remove unused extern decls.
8358 (struct iso_2022_spec, struct coding_system):

8360 (struct emacs_mule_spec): Remove unused field 'full_support'.
8361 All initializations removed.
8362 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
8364 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8366 Fix spare memory change (Bug#12286).
8367 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
8368 (valid_lisp_object_p): Likewise.
8370 2012-08-27 Martin Rudalics <rudalics@gmx.at>
8372 * window.c (Fset_window_configuration): Record any window's old
8373 buffer if it's replaced (see Bug#8789). If the new current
8374 buffer doesn't appear in the selected window, go to its old
8377 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
8379 Special MEM_TYPE_SPARE to denote reserved memory.
8380 * alloc.c (enum mem_type): New memory type.
8381 (refill_memory_reserve): Use new type for spare memory.
8382 This prevents live_cons_p and live_string_p from incorrect
8383 detection of uninitialized objects from spare memory as live.
8385 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
8388 * Makefile.in (.PHONY): versioclean -> versionclean.
8390 Remove unused external symbols.
8391 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
8392 * window.c (Qwindow_valid_p, decode_valid_window):
8393 Now static, not extern.
8394 * data.c (Qinterval): Remove; unused.
8395 (syms_of_data): Do not define 'interval'.
8396 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
8397 * window.h (decode_valid_window):
8400 * character.c, charset.c, chartab.c: Use bool for booleans.

8410 (char_table_set_range, optimize_sub_char_table)
8411 (map_sub_char_table):
8412 Use bool for boolean.
8413 * character.c (str_to_unibyte): Omit last boolean argument; it was
8414 always 0. All callers changed.
8415 * character.h, charset.h: Adjust to match previous changes.
8416 * character.h (char_printable_p): Remove decl of nonexistent function.
8417 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
8418 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
8419 are all boolean, so make them single-bit bitfields.
8421 * lisp.h (ASET): Remove attempt to detect side effects.
8422 It was meant to be temporary and it often doesn't work,
8423 because when IDX has side effects the behavior of IDX==IDX
8424 is undefined. See Stefan Monnier in
8425 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
8427 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
8429 * lisp.h (functionp): New function (extracted from Ffunctionp).
8430 (FUNCTIONP): Use it.
8431 * eval.c (Ffunctionp): Use it.
8433 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8435 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
8436 as that's faster and simpler than static storage. Don't bother
8437 with the g_main_context_query overhead if g_main_context_pending
8438 says no events are pending.
8439 (gfds, gfds_size): Remove these static vars.
8440 (xgselect_initialize): Remove; no longer needed.
8441 All uses and decls removed.
8443 * emacs.c (fatal_error_signal_hook): Remove.
8444 All uses removed. This leftover from old code was always 0.
8446 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
8447 * casefiddle.c (casify_object, casify_region):
8448 * casetab.c (set_case_table):
8449 * category.c, category.h (word_boundary_p):
8450 * category.h (CHAR_HAS_CATEGORY):
8451 Use bool for booleans, instead of int.
8453 2012-08-25 Eli Zaretskii <eliz@gnu.org>
8455 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
8457 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8459 On assertion failure, print backtrace if available.
8460 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
8461 (die) [ENABLE_CHECKING]: Print a backtrace if available.
8462 * Makefile.in (LIB_EXECINFO): New macro.
8465 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
8466 * bytecode.c (exec_byte_code):
8467 * callint.c (check_mark, Fcall_interactively):
8468 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
8469 (getenv_internal, sync_process_alive, call_process_exited):
8470 * lisp.h (USE_SAFE_ALLOCA):
8471 Use bool for booleans, instead of int.
8472 * lisp.h, process.h: Adjust prototypes to match above changes.
8473 * callint.c (Fcall_interactively): Don't assume the mark's
8474 offset fits in 'int'.
8476 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
8478 * buffer.c, buffer.h: Use bool for boolean.
8479 * buffer.c (reset_buffer_local_variables)
8480 (buffer_lisp_local_variables, Fset_buffer_modified_p)

8484 (report_overlay_modification, call_overlay_mod_hooks):
8485 (mmap_enlarge, mmap_set_vars):
8486 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
8487 Use bool for booleans, instead of int.
8488 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
8489 since the 1-or-0 return value is always ignored anyway.
8490 (mmap_initialized_p):
8491 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
8492 * buffer.h, lisp.h: Adjust prototypes to match above changes.
8494 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8496 * bidi.c: Use bool for boolean.
8497 This is a bit more readable, and makes the text segment of bidi.o
8498 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
8499 Presumably it's faster too.
8500 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
8502 (bidi_cache_find_level_change, bidi_cache_iterator_state)
8503 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
8504 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
8505 (bidi_explicit_dir_char, bidi_level_of_next_char)
8506 (bidi_find_other_level_edge, bidi_move_to_visually_next):
8507 Use bool for booleans, instead of int.
8508 * dispextern.h (bidi_init_it, bidi_paragraph_init)
8509 (bidi_unshelve_cache): Adjust decls to match code.
8511 2012-08-23 Martin Rudalics <rudalics@gmx.at>
8513 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
8516 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8518 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
8519 * atimer.h: Include <stdbool.h>.
8521 2012-08-22 Dan Nicolaescu <dann@gnu.org>
8523 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
8524 compile time tests instead of run time tests on systems that do
8526 (FRAME_MAC_P): Remove leftover from deleted code.
8527 * frame.c (syms_of_frame): Remove leftover from deleted code.
8529 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
8531 * nsterm.m (insertText:): Don't clear modifiers if code is space.
8533 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
8535 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
8536 Otherwise, the compiler complains about (A?B:C) where B is void
8537 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
8538 (fontset_add): Return void, for FONTSET_ADD.
8540 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8542 * alloc.c: Use bool for booleans.
8543 (gc_in_progress, abort_on_gc)
8544 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8545 (dont_register_blocks) [GC_MALLOC_CHECK]:
8546 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
8547 (check_string_bytes, make_specified_string, memory_full)
8548 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
8549 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
8550 (mark_stack, valid_pointer_p, make_pure_string)
8551 (Fgarbage_collect, survives_gc_p, gc_sweep):
8552 Use bool for booleans, instead of int.
8553 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8554 Remove unused local.
8555 * alloc.c (PURE_POINTER_P):
8556 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
8557 * editfns.c (Fformat):
8558 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
8560 * fns.c (sweep_weak_table):
8561 * lisp.h (suppress_checking, push_message, survives_gc_p)
8562 (make_pure_string, gc_in_progress, abort_on_gc):
8563 * lread.c (readchar, read1):
8564 * print.c (Fprin1_to_string):
8565 * xdisp.c (push_message):
8566 Use bool for booleans affected directly or indirectly by
8569 Make recently-introduced setters macros.
8570 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
8571 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
8572 (set_fontset_default, set_fontset_fallback): Rename from their
8573 upper-case counterparts, and make them functions rather than macros.
8574 This is more consistent with the other recently-introduced setters.
8575 These don't need to be inline, since they're local.
8577 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
8579 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
8580 the loop (Bug#12247).
8582 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8584 * lisp.h (vcopy): Use memcpy rather than our own loop.
8585 This fixes a performance regression introduced by the recent
8586 addition of vcopy. This means 'vcopy' will need to be modified
8587 for a copying collector, but that's OK. Also, tighten the
8588 checking in the assertion.
8590 2012-08-21 Eli Zaretskii <eliz@gnu.org>
8592 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
8593 components for RTL text (Bug#11860). Adjust X-OFFSET of each
8594 non-base glyph for the width of the base character, according to
8595 what x_draw_composite_glyph_string_foreground expects.
8596 Generate WADJUST value according to composition_gstring_width's
8597 expectations, to produce correct width of the composed character.
8598 Reverse the sign of the DU offset produced by ScriptPlace.
8600 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8602 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
8604 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8606 Avoid direct writes to contents member of struct Lisp_Vector.
8607 * lisp.h (vcopy): New function to copy data into vector.
8608 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
8609 * fns.c (Ffillarray): Use ASET.
8610 * keyboard.c (timer_check_2): Use AREF and ASET.
8611 (append_tool_bar_item, Frecent_keys): Use vcopy.
8612 * lread.c (read_vector): Use ASET.
8613 * msdos.c (Frecent_doskeys): Use vcopy.
8614 * xface.c (Finternal_copy_lisp_face): Use vcopy.
8615 (Finternal_merge_in_global_face): Use ASET and vcopy.
8616 * xfont.c (xfont_list_pattern): Likewise.
8618 2012-08-21 Martin Rudalics <rudalics@gmx.at>
8620 * window.c (Fwindow_point): For the selected window always return
8621 the position of its buffer's point.
8622 (Fset_window_point): For the selected window always go in its
8623 buffer to the specified position.
8625 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8627 Setter macros for fontsets.
8628 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
8629 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
8630 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8633 2012-08-20 Glenn Morris <rgm@gnu.org>
8635 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8636 Don't assume that `ln -f' works.
8638 2012-08-20 Eli Zaretskii <eliz@gnu.org>
8640 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8641 and later about non-assignments with no effect. See discussion at
8642 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
8645 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8647 Inline setter functions for Lisp_Objects slots of struct specbinding.
8648 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
8651 2012-08-20 Martin Rudalics <rudalics@gmx.at>
8653 * window.c (select_window): Always make selected window's buffer
8656 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8658 Use AREF and ASET for docstrings of category tables.
8659 * category.h (CATEGORY_DOCSTRING): Use AREF.
8660 (SET_CATEGORY_DOCSTRING): Use ASET.
8661 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
8663 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8665 Inline setter functions for hash table members.
8666 * lisp.h (set_hash_key, set_hash_value, set_hash_next)

8684 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8686 Rely on <config.h> + <unistd.h> to declare 'environ',
8687 as gnulib does this if the system doesn't.
8688 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

9557 2012-08-04 Eli Zaretskii <eliz@gnu.org>
9559 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
9560 * w32.c (init_environment): Change the default values of many
9561 environment variables in dflt_envvars[] to NULL, to avoid pushing
9562 them into environment when they were not already defined.
9563 Remove the code that deletes site-lisp subdirectories from the default
9564 value of EMACSLOADPATH, as it is no longer needed.
9565 (check_windows_init_file): Now external, not static.
9566 Use Vload_path as is, without adding anything, as this function is now
9567 called when Vload_path is already set up.
9569 * w32.h (check_windows_init_file): Add prototype.
9571 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
9572 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
9573 compatibility with Posix platforms.
9574 (main): Move the call to check_windows_init_file to here from
9576 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
9577 any, in the DEFALT argument into the root of the Emacs build or
9578 installation tree, as appropriate.
9580 * callproc.c (init_callproc_1): Call decode_env_path instead of
9581 doing its equivalent by hand.
9582 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
9583 the code that sets Vexec_path run on MS-Windows.
9585 * lread.c (init_lread): Add comments to #ifdef's.
9587 * msdos.c (dos_set_window_size, IT_update_begin)
9588 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
9589 instead of direct references.
9591 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
9593 Export DEFAULT_REHASH_* to GDB.
9594 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
9595 Now constants, not macros.
9597 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
9599 Remove unnecessary casts involving pointers.
9600 These casts are no longer needed now that we assume C89 or later,
9601 since they involve casting to or from void *.
9602 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
9603 (make_pure_float, make_pure_vector):
9604 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

9613 (x_get_window_property, x_get_window_property_as_lisp_data):
9614 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
9615 Remove unnecessary pointer casts.
9616 * alloc.c (record_xmalloc): New function.
9617 * lisp.h (record_xmalloc): New decl.
9618 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
9619 more like a function. This is because the pointer cast is not
9620 needed. All uses changed.
9621 * print.c (print_string, print_error_message): Avoid length recalc.
9623 Improve fix for macroexp crash with debugging (Bug#12118).
9624 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
9625 ARRAY_MARK_FLAG when checking subscripts, because ASET is
9626 not supposed to be invoked from the garbage collector.
9627 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
9628 (gc_aset): New function, which is like ASET but can be
9629 used in the garbage collector.
9630 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
9631 (set_hash_index): Use it instead of ASET.

9640 <g_b_init_create_symbolic_link>: New static flags.
9641 (globals_of_w32): Initialize them to zero.
9642 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
9643 (map_w32_filename): Improve commentary. Simplify switch.
9644 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
9645 headers (most versions of MinGW w32api don't).
9646 (get_security_info, create_symbolic_link)
9647 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
9649 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
9650 in the argument file name.
9651 (sys_access): Call unc_volume_file_attributes only if
9652 GetFileAttributes fails with network-related error codes.
9653 (sys_rename): Diagnose renaming of a symlink when the user doesn't
9654 have the required privileges.
9655 (get_file_security_desc_by_name): Rename from
9656 get_file_security_desc.
9657 (stat_worker): New function, with most of the guts of 'stat', and
9658 with addition of handling of symlinks and support for 'lstat'.
9659 If possible, get file's attributes and security information by
9660 handle, not by name. Produce S_IFLNK bit for symlinks, when
9661 called from 'lstat'.
9662 (stat, lstat): New functions, call 'stat_worker'.
9663 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9664 symlinks when the underlying filesystem supports them.
9666 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
9668 Fix macroexp crash on Windows with debugging (Bug#12118).
9669 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9670 checking subscripts; problem introduced with the recent
9671 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9672 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9673 since it's used in non-static inline functions now.
9675 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9676 Don't assume buffer size fits in 'int'. Remove unused local.
9678 Use C99-style 'extern inline' if available.

9680 * category.h (CATEGORY_INLINE):
9681 * character.h (CHARACTER_INLINE):

9688 * buffer.h, category.h, character.h, charset.h, composite.h:
9689 * dispextern.h, lisp.h, systime.h:
9690 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
9691 * alloc.c (LISP_INLINE):
9692 * buffer.c (BUFFER_INLINE):
9693 * category.c (CATEGORY_INLINE):
9694 * character.c (CHARACTER_INLINE):
9695 * charset.c (CHARSET_INLINE):
9696 * composite.c (COMPOSITE_INLINE):
9697 * dispnew.c (DISPEXTERN_INLINE):
9698 * sysdep.c (SYSTIME_INLINE):
9699 Define to EXTERN_INLINE, so that the corresponding functions
9700 are compiled into code.
9701 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
9702 (INLINE_HEADER_END): New macros.
9703 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9723 hard-coding the path separator.
9725 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9727 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9728 This how ASET and AREF are supposed to work, and makes
9729 it easier to think about future improvements. See
9730 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
9731 * charset.h (set_charset_attr): New function.
9732 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
9733 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

10001 (MANY, UNEVALLED, FLOAT_TO_STRING_BUFSIZE, MAX_ALLOCA):
10002 Now constants, for GDB. They need not be macros.

10005 (CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):
10006 Move to after the definition of struct Lisp_Char_Table,
10007 since the former now needs that type defined.

10033 These macros are confusing and no longer need to be defined, as
10034 the enum values now suffice. All uses replaced with definiens.

10111 w32_console_unicode_input.
10112 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
10113 (w32_kbd_patch_key, key_event): Use the codepage returned by

10146 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
10147 enumeration constants, as PURE and HEAP are too general, and clash
10148 with other headers and sources, such as gmalloc.c and the
10149 MS-Windows system headers. All users changed.
10151 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10153 Revert last save_excursion_save and save_excursion_restore changes.
10154 * alloc.c, editfns.c, marker.c, lisp.h: Revert.
10155 Lots of crashes reported by Chong Yidong <cyd@gnu.org>.
10157 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10159 Fix recently-introduced typos in Windows port.
10160 Reported by Martin Rudalics <rudalics@gmx.at>.

10162 * w32fns.c (syms_of_w32fns): Add missing parenthesis.
10164 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
10166 Improve GDB symbol export (Bug#12036).
10167 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
10168 arms of an 'if', not using conditional expressions; otherwise GDB
10169 complains about the types in the unevaluated arm when the argument
10170 is an integer literal.
10171 (xgetint): Simplify expression.
10172 * alloc.c (gdb_make_enums_visible): New constant. This ports to
10173 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
10174 Zaretskii in <http://bugs.gnu.org/12036#13>.
10175 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
10176 needed now that we have gdb_make_enums_visible.
10177 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
10178 (enum enum_USE_LSB_TAG):
10179 New enum types, packaging up enums that need to be exported to GDB.
10181 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
10183 Utility function to make a list from specified amount of objects.
10184 * lisp.h (enum constype): New datatype.
10185 (listn): New prototype.
10186 * alloc.c (listn): New function.
10187 (Fmemory_use_count, syms_of_alloc): Use it.

10202 Fast save_excursion_save and save_excursion_restore.
10203 * lisp.h (struct Lisp_Excursion): New data type.
10204 (PVEC_EXCURSION): New pseudovector type.
10205 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
10206 to deal with it. Adjust comments.
10207 (init_marker, attach_marker): New prototype.
10208 (unchain_marker): Adjust prototype.
10209 * marker.c (attach_marker): Change to global.
10210 (init_marker): New function.

10220 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
10221 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
10222 emacs.c, as this is a more-suitable home. Had this been done earlier
10223 the fix for 12036 would have avoided some of the problems noted in
10224 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
10225 would have been more obvious.
10226 * emacs.c: Do not include <verify.h>; no longer needed.
10227 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)

10229 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10230 Remove; now done in lisp.h.
10231 * lisp.h (PUBLISH_TO_GDB): New macro.

10234 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
10235 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
10236 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
10237 not be usable in #if. This simplifies things.
10239 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
10241 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
10243 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
10245 Simplify export of symbols to GDB (Bug#12036).
10246 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
10247 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
10248 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
10249 Adjust to changes in lisp.h and emacs.c, by using
10250 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
10251 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
10252 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
10253 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
10254 instead of gdb_valbits.
10255 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
10256 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
10257 instead of gdb_array_mark_flag.
10258 (xboolvector): Get size from $->size, not $->header.size.
10259 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
10260 (xreload, hook-run, hookpost-run): Remove.
10261 * emacs.c: Include <verify.h>.
10262 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
10263 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
10265 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
10266 (gdb_USE_LSB_TAG): New enum constants.
10267 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
10268 Also define these as enum constants, so they're visible to GDB.
10269 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
10270 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
10271 as constants, so they're visible to GDB.
10272 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
10273 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
10274 Now enum constants, not macros, so they're visible to GDB.
10275 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
10276 more convenient now. All uses changed.
10277 (VALMASK) [USE_LSB_TAG]: Also define in this case.
10278 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
10280 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
10282 Explicitly free restriction data that are not needed anymore.
10283 * editfns.c (save_restriction_restore): Free restriction data.
10285 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
10287 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
10288 add argument, tune behavior, and adjust all callers.
10290 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
10292 Use typedef for EMACS_INT, EMACS_UINT.
10293 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
10294 than macros. This simplifies debugging in the usual case, since
10295 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
10296 and it allows expressions involving EMACS_INT casts.
10297 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
10299 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
10301 * nsterm.m (ns_read_socket): Return early if there is a modal
10302 window (Bug#12043).
10304 2012-07-25 Martin Rudalics <rudalics@gmx.at>
10306 * frame.c (Fredirect_frame_focus): In doc-string don't mention
10307 that FOCUS-FRAME can be omitted.
10309 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
10311 Adjust buffer text indirection counters at the end of Fkill_buffer.
10312 * buffer.c (Fkill_buffer): Adjust indirection counters when the
10313 buffer is definitely dead. This should really fix an issue reported
10314 by Christoph Scholtes again. (Bug#12007).
10315 (init_buffer_once): Initialize indirection counters of
10316 buffer_defaults and buffer_local_symbols (for sanity and safety).
10318 2012-07-24 Eli Zaretskii <eliz@gnu.org>
10320 * xdisp.c (init_iterator): Don't compute dimensions of truncation
10321 and continuation glyphs on tooltip frames, leave them at zero.
10322 Avoids continued lines in tooltips. (Bug#11832)
10324 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
10326 Simplify copy_overlay.

10332 * print.c (print_object): Don't crash when a frame's name is nil
10333 or invalid. (Bug#12025)
10335 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
10336 it signals an error when a tooltip frame is being created.
10338 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
10340 Cleanup miscellaneous objects allocation and initialization.
10341 * alloc.c (allocate_misc): Change to static. Add argument to
10342 specify the subtype. Adjust comment and users.
10343 (build_overlay): New function.
10344 * buffer.c (copy_overlays, Fmake_overlay): Use it.
10345 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
10346 (allocate_misc): Remove prototype.
10347 (build_overlay): Add prototype.
10349 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
10351 Swap buffer text indirection counters in Fbuffer_swap_text.
10352 * buffer.c (Fbuffer_swap_text): Swap indirections too.
10353 This avoids crash reported by Christoph Scholtes at
10354 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
10356 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
10358 * nsmenu.m (Popdown_data): New struct.
10359 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
10361 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
10362 (initWithContentRect): Make imgView and contentView non-static
10363 and autorelease them. Also autorelease img and matrix (Bug#12005).
10364 (dealloc): Remove (Bug#12005).
10366 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
10368 Adjust consing_since_gc when objects are explicitly freed.
10369 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
10370 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
10371 (free_cons, free_misc): Subtract object size from consing_since_gc.
10373 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
10375 Simplify and cleanup markers positioning code.
10376 * marker.c (attach_marker): More useful eassert.
10377 (live_buffer, set_marker_internal): New function.
10378 (Fset_marker, set_marker_restricted): Use set_marker_internal.
10379 (set_marker_both, set_marker_restricted_both): Use live_buffer.
10381 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
10383 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
10384 as it's limited by the amount of memory, not by INT_MAX.
10386 2012-07-21 Eli Zaretskii <eliz@gnu.org>
10388 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
10389 in special-event-map. See the discussion at

10393 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
10394 info.dwItemData. Fixes crashes on 64-bit Windows.

11112 * s/aix4-2.h (unix): Remove; no longer needed.
11114 EMACS_TIME simplification (Bug#11875).
11115 This replaces macros (which typically do not work in GDB)

11117 The functional style also makes code easier to read and maintain.
11118 * systime.h: Include <sys/time.h> on all hosts, not just if
11119 WINDOWSNT, since 'struct timeval' is needed in general.
11120 (EMACS_TIME): Now a typedef, not a macro.

11154 (menu_separator_name_p):
11155 * nsmenu.m (ns_update_menubar):
11156 Prefer memcmp to strncmp when either will do.
11157 * nsterm.m: Include <ftoastr.h>.
11159 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
11160 Prefer snprintf to strncpy.
11161 * nsterm.m (ns_term_init):
11162 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
11163 * nsterm.m (ns_term_init):
11164 Avoid the need for strncpy, by using build_string or
11165 make_unibyte_string directly. Use dtoastr, not snprintf.
11166 * process.c (Fmake_network_process): Diagnose service names that
11167 are too long, rather than silently truncating them or creating
11168 non-null-terminated names.
11169 (Fnetwork_interface_info): Likewise, for interface names.
11170 * sysdep.c (system_process_attributes) [GNU_LINUX]:
11171 Prefer sprintf to strncat.

11184 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
11185 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

11201 provides a better opportunity to optimize away calls to strlen when
11202 the function is called with compile-time constant argument.
11203 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
11204 argument, adjust users accordingly. Use build_pure_c_string where

11207 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
11208 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

11235 * s/gnu.h (DATA_START): Move definitions to configure.
11237 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
11238 We include usg5-4-common.h, which defines them both.
11240 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
11241 O_RDONLY already includes it).
11243 Stop ns builds setting the EMACSLOADPATH environment variable.
11244 * nsterm.m (ns_load_path): Rename from ns_init_paths.
11245 Now it does not set EMACSLOADPATH, just returns the load-path string.
11246 * nsterm.h: Update accordingly.
11247 * lread.c [HAVE_NS]: Include nsterm.h.
11248 (init_lread) [HAVE_NS]: Use ns_load_path.

11258 (ns_init_paths): Do not set EMACSPATH.

11260 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
11263 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
11265 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
11267 * process.c (wait_reading_process_output): 'waitchannels' was unset
11268 when read_kbd || !NILP (wait_for_cell); fix this.
11270 Add GCC-style 'const' attribute to functions that can use it.
11271 * character.h (char_resolve_modifier_mask):
11272 * keyboard.h (make_ctrl_char):
11273 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
11274 (init_character_once, next_almost_prime, init_fns, init_image)
11275 (flush_pending_output, init_sound):
11276 * mem-limits.h (start_of_data):

11282 Add decls with ATTRIBUTE_CONST.
11284 Minor improvements to make_formatted_string.
11285 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
11286 where int is good enough, as vsprintf returns an int.
11287 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
11289 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
11291 Use make_formatted_string to avoid double length calculation.
11292 * lisp.h (make_formatted_string): New prototype.
11293 * alloc.c (make_formatted_string): New function.
11294 * buffer.c (Fgenerate_new_buffer_name): Use it.
11295 * dbusbind.c (syms_of_dbusbind): Likewise.

11314 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
11316 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
11318 Move marker debugging code under MARKER_DEBUG.
11319 * marker.c (MARKER_DEBUG): Move marker debugging code under
11320 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
11321 for bootstrap with --enable-checking (~3x slowdown reported
11322 by Juanma Barranquero <lekktu@gmail.com>).
11323 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
11325 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
11327 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
11328 See <http://bugs.gnu.org/11825#29>.
11330 2012-07-08 Eli Zaretskii <eliz@gnu.org>
11332 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
11333 has no font, use the frame's font. (Bug#11813)
11334 (display_line): Add commentary about displaying truncation glyphs
11336 (produce_special_glyphs): Move here from term.c.
11338 * term.c (produce_special_glyphs): Move to xdisp.c.
11340 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
11343 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
11345 * xdisp.c (display_line): Avoid warning about implicit declaration
11348 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
11350 * lisp.h: Remove empty conditional.
11352 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11354 * lread.c (load_path_check): Now static.
11356 Fix some minor --with-ns problems found by static checking.
11357 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
11358 (x_set_font) [!HAVE_X_WINDOWS]:
11359 * image.c (xpm_load_image) [HAVE_NS]:
11360 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
11361 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
11362 Remove unused local.
11363 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
11364 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
11365 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
11366 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
11367 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
11368 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
11369 Fix pointer signedness problem.
11370 * xfaces.c (FRAME_X_FONT_TABLE):
11371 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
11373 2012-07-07 Glenn Morris <rgm@gnu.org>
11375 * lread.c (load_path_check): New function, split from init_lread.
11376 (init_lread): Reorganize. Motivation:
11377 If EMACSLOADPATH is set, check/warn about that rather than the
11378 defaults, which we are not going to use. Hence we can remove
11379 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
11380 Don't warn if site-lisp directories are missing.
11381 If not installed, start from a blank load-path, since
11382 PATH_LOADSEARCH refers to the eventual installation directories.
11384 2012-07-07 Eli Zaretskii <eliz@gnu.org>
11386 Support truncation and continuation glyphs on GUI frames, when
11387 fringes are disabled. (Bug#11832)
11388 * xdisp.c (init_iterator): Get dimensions of truncation and
11389 continuation glyphs even if on GUI frames.
11390 Adjust it->last_visible_x on GUI frames when the left or right fringes,
11391 or both, are absent.
11392 (start_display, move_it_in_display_line_to): Handle the case of a
11393 GUI frame without a fringe to display continuation or truncation
11395 (insert_left_trunc_glyphs): Support GUI frames: make sure
11396 truncation glyphs overwrite enough glyphs from the current line to
11397 have sufficient space in pixels.
11398 (display_line): Support truncation and continuation glyphs on GUI
11399 frames. If some spare pixels are left on the line after inserting
11400 the truncation glyphs, fill that space with a stretch glyph of a
11401 suitably computed width.
11403 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
11404 produce_glyphs, to support GUI sessions.
11406 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
11408 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
11410 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
11412 Do not require float-time's arg to fit in time_t (Bug#11825).
11413 This works better on hosts where time_t is unsigned, and where
11414 float-time is applied to the (negative) difference between two times.
11415 * editfns.c (decode_time_components): Last arg is now double *,
11416 not int *, and means to store all the result as a double, without
11417 worrying about whether the seconds part fits in time_t.
11418 All callers changed.
11419 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
11420 All callers changed.
11421 (Ffloat_time): Do not fail merely because the specified time falls
11422 outside of time_t range.
11424 2012-07-07 Glenn Morris <rgm@gnu.org>
11426 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
11427 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
11428 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
11430 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
11432 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
11433 Update dependencies.

11441 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
11442 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
11443 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
11444 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
11446 * xfont.c (compare_font_names): Redo to omit the need for casts.
11448 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
11450 * xfns.c (Fx_change_window_property): Doc fix.
11451 * w32fns.c (Fx_change_window_property): Doc fix.
11453 * w32fns.c (Fx_window_property): Accept the same arguments as the
11454 X Windows version. Doc fix.
11455 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
11457 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
11458 Eli Zaretskii <eliz@gnu.org>
11460 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
11461 Windows-specific code from nt/config.nt moved here.
11462 Obsolete settings removed.
11464 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11466 * process.c: Avoid unnecessary calls to gettime.
11467 (wait_reading_process_output): Don't get the time of day
11468 when gobbling data immediately and not waiting, as there's no need
11469 for it in that case. This removes a FIXME.
11471 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
11473 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
11474 is defined (Bug#11768).
11476 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11478 Fix marker debugging code.
11479 * marker.c (byte_char_debug_check): Do not perform the check
11480 if buffer is not multibyte.
11481 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11482 Call byte_char_debug_check with correct arguments.
11484 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11486 Compile marker debugging code only if ENABLE_CHECKING is defined.
11487 * marker.c (byte_char_debug_check, count_markers):
11488 Use only if ENABLE_CHECKING is defined.
11489 (byte_debug_flag): Remove.
11490 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11491 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
11493 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11495 Avoid code repetition in marker-related functions.
11496 * marker.c (attach_marker): New function.
11497 (Fset_marker, set_marker_restricted, set_marker_both)

11500 Consistently rename charno to charpos.
11501 (marker_position): Add eassert.
11502 (marker_byte_position): Convert to eassert.
11504 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

11518 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
11519 (save_restriction_save): Use build_marker.
11520 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
11521 * window.c (save_window_save): Likewise.
11523 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11525 Do not use Fdelete_overlay in delete_all_overlays
11526 to avoid redundant calls to unchain_overlay.
11527 * buffer.c (drop_overlay): New function.
11528 (delete_all_overlays, Fdelete_overlay): Use it.
11529 * minibuf.c (get_minibuffer): Fix comment.
11531 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11533 Port to OpenBSD 5.1 amd64.
11534 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
11535 This is needed for OpenBSD, and should be harmless on all BSD systems.
11536 Also, include <sys/sysctl.h>, as it should be available on all
11537 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
11538 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
11539 use p_pid member, not kp_proc.pid.
11541 2012-07-06 Glenn Morris <rgm@gnu.org>
11543 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
11545 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11547 More xmalloc and related cleanup.
11548 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
11549 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
11550 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

11556 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
11558 Omit needless casts involving void * pointers and allocation.
11559 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
11560 as the former is more robust if P's type is changed.
11561 Prefer xzalloc to xmalloc + memset 0.
11562 Simplify malloc-or-realloc to realloc.
11563 Don't worry about xmalloc returning a null pointer.
11564 Prefer xstrdup to xmalloc + strcpy.
11565 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
11567 * keyboard.c (apply_modifiers_uncached): Prefer local array to
11568 alloca of a constant.
11570 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11572 * xdisp.c (display_line): Fix horizontal pixel coordinates when
11573 hscroll is larger than the line width. Fixes long and futile
11574 looping inside extend_face_to_end_of_line (on a TTY) producing
11575 glyphs that are not needed and thrown away.
11577 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
11579 * marker.c (set_marker_restricted_both): Simplify by using
11582 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

11593 followed by gtk_box_set_homogeneous (Bug#11768).
11594 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
11595 (update_theme_scrollbar_width, xg_create_scroll_bar):
11596 Use gtk_scrollbar_new (Bug#11768).
11597 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
11598 (is_box_type): New function (Bug#11768).
11599 (xg_tool_item_stale_p): Call is_box_type.
11600 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
11601 with default display (Bug#11768).
11603 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11605 * xdisp.c (window_hscroll_limited): New function.
11606 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
11607 coordinates when window's hscroll is set to insanely large
11608 values. (Bug#11857)
11610 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
11612 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

11671 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11673 * fileio.c (time_error_value): Check the right error number.
11674 Problem reported by Troels Nielsen in
11675 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11677 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11679 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11680 This should be fixed in a better way; see Eli Zaretskii in
11681 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11682 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11684 * fileio.c (time_error_value): Rename from special_mtime.
11685 The old name's problems were noted by Eli Zaretskii in
11686 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11688 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11689 This variable's comment says Emacs needs at least one GDB-visible
11690 symbol of type enum pvec_type, to work around GDB problems.
11691 The symbol's value doesn't matter.
11693 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11694 that causes compilation to fail on pre-C99 compilers.
11696 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11698 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

11701 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11703 * buffer.c (init_buffer_once): Fix initialization of
11704 headers for buffer_defaults and buffer_local_symbols.
11705 Reported by Juanma Barranquero <lekktu@gmail.com>.
11707 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11709 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
11710 * lisp.h (enum pvec_type): Use fewer bits.
11711 (PSEUDOVECTOR_SIZE_BITS): New constant.
11712 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
11713 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
11714 change in pvec_type.
11715 (PSEUDOVECTOR_TYPEP): New macro.
11716 (TYPED_PSEUDOVECTORP): Use it.
11717 * fns.c (internal_equal): Adapt code to extract pvectype.
11718 * emacs.c (gdb_pvec_type): Update type.
11719 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
11720 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
11721 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
11722 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11723 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11724 abusing vector->header.next.nbytes.
11725 (live_vector_p): Use PVEC_TYPE.
11726 (mark_object): Adapt code to extract pvectype. Use switch.
11728 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11730 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11731 Tighten new eassert a bit.
11733 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11735 Fix compilation with --enable-gcc-warnings and -O1
11736 optimization level.
11737 * doprnt.c (doprnt): Change type of tem to int, initialize
11738 to avoid compiler warning. Add eassert.
11739 * search.c (simple_search): Initialize match_byte to avoid
11740 compiler warning. Add eassert.
11742 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11744 Avoid weird behavior with large horizontal scrolls.
11745 Without this change, for example, large hscroll values would
11746 mess up Emacs's display on Fedora 15 x86, presumably due to
11747 overflows in int calculations in the display code.
11748 Also, if buffers had long lines, Emacs would freeze.
11749 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11750 (set_window_hscroll): New function, containing the old guts of
11751 Fset_window_hscroll. Return the clipped value.
11752 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11753 This avoids the need to check against PTRDIFF_MAX.
11755 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11757 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11759 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11761 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11763 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11764 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11765 since GCC 4.4.6 issues a bogus warning for them.
11767 Fix bugs in file timestamp newness comparisons.
11768 * fileio.c (Ffile_newer_than_file_p):
11769 * lread.c (Fload): Use full timestamp resolution of files,
11770 not just the 1-second resolution, so that files that are only
11771 slightly newer still count as newer.
11772 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11773 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11775 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11777 * fileio.c: Improve handling of file time marker. (Bug#11852)
11778 (special_mtime): New function.
11779 (Finsert_file_contents, Fverify_visited_file_modtime):
11780 Use it to set special mtime values consistently.
11782 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11784 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11785 marker for non-existing file. (Bug#11852)
11787 2012-07-03 Glenn Morris <rgm@gnu.org>
11789 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11790 and did not make it into globals.h).
11792 2012-07-03 Tom Tromey <tromey@redhat.com>
11794 * window.c (Fset_window_margins, Fset_window_fringes)
11795 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
11796 * textprop.c (Fprevious_property_change): No longer static.
11797 * syntax.c (Fsyntax_table_p): No longer static.
11798 * process.c (Fget_process, Fprocess_datagram_address): No longer

11821 * font.h: Remove EXFUNs.
11822 * dosfns.c (system_process_attributes): Remove EXFUN.
11823 * keymap.h: Remove EXFUNs.
11824 * lisp.h: Remove EXFUNs.
11825 * w32term.h: Remove EXFUNs.
11826 * window.h: Remove EXFUNs.
11827 * xsettings.h: Remove EXFUN.
11828 * xterm.h: Remove EXFUN.
11830 2012-07-03 Glenn Morris <rgm@gnu.org>
11832 * lisp.h (Frandom): Make it visible to C.
11833 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11834 buffer for invisible buffers. (Bug#1229)
11836 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11838 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11839 values which aren't power of 2.
11840 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11841 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11844 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11846 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11848 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11850 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11852 * alloc.c (allocate_vector_block): Remove redundant
11853 calls to mallopt if DOUG_LEA_MALLOC is defined.
11854 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11855 avoid calls to mallopt if zero_vector is returned.
11857 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11859 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11860 is enabled, avoid dereferencing NULL current_sblock if
11863 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11865 Cleanup basic buffer management.
11866 * buffer.h (struct buffer): Change layout to use generic vector
11867 marking code. Fix some comments. Change type of 'clip_changed'
11868 to bitfield. Remove unused #ifndef old.
11869 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11870 (GET_OVERLAYS_AT): Fix indentation.
11871 (for_each_per_buffer_object_at): New macro.
11872 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
11873 (Fbuffer_local_variables): Use it.
11874 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.

11876 struct buffer. Fix comment.
11877 (mark_overlay): New function.
11878 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11879 Lisp area of struct buffer.
11880 (mark_object): Use it. Adjust marking of misc objects
11881 and related comments.
11883 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11885 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11886 wrapper that is not needed because the wrapped code is a no-op (zero
11887 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11888 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11890 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11892 * alloc.c (mark_buffer): Simplify. Remove prototype.
11893 (mark_object): Add comment. Reorganize marking of vector-like
11894 objects. Use CHECK_LIVE for all vector-like objects except buffers
11895 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11896 Avoid redundant calls to mark_vectorlike for bool vectors.
11898 2012-06-30 Glenn Morris <rgm@gnu.org>
11900 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11902 * epaths.in (PATH_SITELOADSEARCH): New.
11903 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11904 This is rather than relying on --enable-locallisppath elements
11905 having "site-lisp" in their names. (Bug#10208#25, 11658)
11907 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11909 * w32proc.c (sys_select): Accept and ignore one more argument.
11911 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11913 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11914 (pselect) [!MS_DOS]: Redirect to sys_select.
11916 * sysdep.c: Don't include dos.h and dosfns.h.
11918 * process.c (sys_select):
11919 * msdos.c (sys_select): Accept one more argument and ignore it.
11921 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11922 adapt data types and code to that.
11925 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11926 which clashes with the gnulib function of the same name.
11928 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11930 * font.c (font_style_to_value, font_style_symbolic)
11931 (font_prop_validate_style): Add type checks for values in
11934 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11936 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11939 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11941 * xdisp.c (try_window_id): Undo last change.
11943 * w32.c (getwd): Adjust commentary about startup_dir.
11944 (init_environment): Always call sys_access, even in non-MSVC
11945 builds. Don't chdir to the directory of the Emacs executable.
11946 This undoes code from 1997 which was justified by the need to
11947 "avoid conflicts when removing and renaming directories". But its
11948 downside was that every relative file name was being interpreted
11949 relative to the directory of the Emacs executable, which can never
11950 be TRT. In particular, it broke sys_access when called with
11951 relative file names.
11952 (sys_access): Map GetLastError to errno.
11954 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11956 * window.h (struct window): Change type of 'fringes_outside_margins'
11957 to bitfield. Fix comment. Adjust users accordingly.
11958 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
11960 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11963 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11965 * gnutls.c (emacs_gnutls_handshake):
11966 Add QUIT to make the loop interruptible.
11968 2012-06-29 Glenn Morris <rgm@gnu.org>
11970 * charset.c (init_charset): Make lack of etc/charsets fatal.
11972 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

11978 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11979 undefined. Convert from xassert to eassert.
11980 * nsmenu.m: Convert from xassert to eassert.
11981 * nsterm.m: Likewise.
11983 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

11987 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11989 Avoid integer overflow on scroll-left and scroll-right.
11990 * window.c (HSCROLL_MAX): New macro.
11991 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11992 overflow when requested scroll falls outside ptrdiff_t range.
11994 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11996 * window.h (struct window): Change type of 'hscroll',
11997 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11998 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11999 Adjust users accordingly.
12000 * xdisp.c (try_cursor_movement): Replace type check with eassert.
12001 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
12002 from EMACS_INT to ptrdiff_t.
12003 (make_window): Omit redundant initialization.
12005 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

12022 Fix GLYPH_DEBUG usage assuming that it may be undefined,
12023 adjust comments accordingly.

12105 when building with Clang.

12144 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
12146 Use sprintf return value instead of invoking strlen on result.
12147 In the old days this wasn't portable, since some sprintf
12148 implementations returned char *. But they died out years ago and
12149 Emacs already assumes sprintf returns int.
12150 Similarly for float_to_string.
12151 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
12152 * ccl.c (ccl_driver):

12156 * print.c (print_object):
12157 * xdisp.c (message_dolog):
12158 * xfns.c (syms_of_xfns):
12159 Use sprintf or float_to_string result to avoid need to call strlen.
12160 * data.c (Fnumber_to_string):
12161 Use make_unibyte_string, since the string must be ASCII.
12162 * lisp.h, print.c (float_to_string): Now returns int length.
12163 * term.c (produce_glyphless_glyph):
12164 Use sprintf result rather than recomputing it.
12166 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
12167 * Makefile.in (ALL_CFLAGS):

12204 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
12205 instead of truncating it to 63 (admittedly a generous limit).
12207 * process.c: Fix spelling and caps in comments.
12209 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

12260 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
12262 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
12263 * lisp.h (WAIT_READING_MAX): New macro.
12264 * dispnew.c (Fsleep_for, sit_for):
12265 * keyboard.c (kbd_buffer_get_event):
12266 * process.c (Faccept_process_output):
12267 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
12268 This improves on the previous patch, which introduced a bug
12269 when time_t is unsigned and as wide as intmax_t.
12270 See <http://bugs.gnu.org/9000#51>.
12272 2012-06-23 Eli Zaretskii <eliz@gnu.org>

12301 language ID in the event parameters.
12303 * w32term.c (w32_read_socket): Put the new keyboard codepage into
12304 event.code, not the obscure "character set ID".
12306 2012-06-23 Chong Yidong <cyd@gnu.org>
12308 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

12335 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
12337 Support higher-resolution time stamps (Bug#9000).
12338 The time stamps are only nanosecond-resolution at the C level,
12339 since that's the best that any real-world system supports now.
12340 But they are picosecond-resolution at the Lisp level, as that's
12341 easy, and leaves room for future OS improvements.
12343 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
12346 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
12347 Don't get current time unless it's needed.
12349 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
12350 now provides it if it's absent.
12351 (start_atimer): Port to higher-res time stamps.
12352 Check for time stamp overflow. Don't get current time more
12353 often than is needed.
12355 * buffer.h (struct buffer): Buffer modtime now has high resolution.
12356 Include systime.h, not time.h.
12357 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
12359 * dired.c: Include stat-time.h.
12360 (Ffile-attributes): File times now have higher resolution.
12362 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
12363 (struct image): Timestamp now has higher resolution.
12365 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
12366 has at least microseconds now. All uses removed.
12367 (update_frame, update_single_window, update_window, update_frame_1)
12368 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
12369 (duration_to_sec_usec): Remove; no longer needed.
12371 * editfns.c (time_overflow): Now extern.
12372 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
12373 (float-time, Fformat_time_string, Fcurrent_time_string)

12377 (decode_time_components, lisp_seconds_argument): New functions.
12378 (make_time): Now static.
12379 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
12380 Report an error if the time is invalid, rather than having the caller
12383 * fileio.c: Include <stat-time.h>
12384 (Fcopy_file): Copy higher-resolution time stamps.
12385 Prefer to set the time stamp via a file descriptor if that works.
12386 (Fset_file_times, Finsert_file_contents, Fwrite_region)
12387 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
12388 (Fvisited_file_modtime, Fset_visited_file_modtime):
12389 Support higher-resolution time stamps.
12391 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
12393 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
12395 * image.c (prepare_image_for_display, clear_image_cache)
12396 (lookup_image): Port to higer-resolution time stamps.
12398 * keyboard.c (start_polling, bind_polling_period):
12399 Check for time stamp overflow.
12400 (read_char, kbd_buffer_get_event, timer_start_idle)
12401 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
12402 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
12403 Port to higher-resolution time stamps. Do not assume time_t is signed.
12404 (decode_timer): New function. Timers are now vectors of length 9,
12405 not 8, to accommodate the picosecond component.
12406 (timer_check_2): Use it.
12408 * nsterm.m (select_timeout, timeval_subtract): Remove.
12409 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
12410 as they're a bit more accurate and handle overflow better.
12411 (ns_select): Change prototype to be compatible with pselect.
12412 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
12413 * nsterm.h (ns_select): Adjust prototype.
12415 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
12416 us-resolution time stamps.
12417 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
12419 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
12421 * lisp.h (time_overflow): New decl.
12422 (wait_reading_process_output): First arg is now intmax_t, not int,
12423 to accommodate larger waits.
12425 * process.h (struct Lisp_Process.read_output_delay):
12426 Now counts nanoseconds, not microseconds.
12427 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
12429 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
12430 (wait_reading_process_output):
12431 Port to ns-resolution time stamps.
12432 (Faccept_process_output, wait_reading_process_output):
12433 Check for time stamp overflow. Do not assume time_t is signed.
12434 (select_wrapper): Remove; we now use pselect.
12435 (Fprocess_attributes): Now generates ns-resolution time stamps.
12437 * sysdep.c: Include utimens.h. Don't include utime.h
12438 or worry about struct utimbuf; gnulib does that for us now.
12439 (gettimeofday): Remove; gnulib provides a substitute.
12440 (make_timeval): New function.
12441 (set_file_times): Now sets ns-resolution time stamps.
12442 New arg FD; all uses changed.
12443 (time_from_jiffies, ltime_from_jiffies, get_up_time)
12444 (system_process_attributes):
12445 Now returns ns-resolution time stamp. All uses changed.
12446 Check for time stamp overflow.
12448 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
12449 provides a substitute now.
12451 * systime.h: Include timespec.h rather than sys/time.h and time.h,
12452 since it guarantees struct timespec.
12453 (EMACS_TIME): Now struct timespec, so that we can support
12454 ns-resolution time stamps.
12455 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
12456 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
12457 (EMACS_USECS): Remove.
12458 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
12459 so multiply the arg by 1000 before storing it.
12460 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
12462 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
12463 Port to ns-resolution time stamps.
12464 (EMACS_TIME_NEG_P): Remove; replaced by....
12465 (EMACS_TIME_SIGN): New macro.

12467 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
12468 (set_file_times, make_time, lisp_time_argument): Adjust signature.
12469 (make_timeval, make_lisp_time, decode_time_components): New decls.
12470 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
12471 that it mishandled time_t overflow. You can't compare by subtracting!
12472 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
12473 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
12475 * term.c: Include <sys/time.h>.
12476 (timeval_to_Time): New function, for proper overflow wraparound.
12477 (term_mouse_position, term_mouse_click): Use it.
12479 * undo.c (record_first_change): Support higher-resolution time stamps
12480 in the undo buffer.
12481 (Fprimitive_undo): Use them when restoring time stamps.
12483 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
12484 (w32_get_internal_run_time):
12485 Port to higher-resolution Emacs time stamps.
12486 (ltime): Now accepts single 64-bit integer, as that's more convenient
12489 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
12491 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
12492 for compatibility with pselect. Support ns-resolution time stamps.
12494 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
12496 * xselect.c (wait_for_property_change, x_get_foreign_selection):
12497 Check for time stamp overflow, and support ns-resolution time stamps.
12499 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
12500 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
12501 (timeval_subtract): Remove; no longer needed.
12502 (XTflash, XTring_bell, x_wait_for_event):
12503 Port to ns-resolution time stamps. Don't assume time_t is signed.
12505 2012-06-22 Chong Yidong <cyd@gnu.org>

12509 2012-06-22 Eli Zaretskii <eliz@gnu.org>
12511 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
12512 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
12513 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
12514 staticidx goes up to 1597 out of 1600 = 0x640.)
12516 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
12518 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
12519 Otherwise, the umask might be mistakenly 0 while handling input signals.
12521 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
12523 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

12530 access to `contents' member of Lisp_Vector objects with AREF and ASET
12533 2012-06-19 Chong Yidong <cyd@gnu.org>
12535 * frame.c (delete_frame): When selecting a frame on a different
12536 text terminal, do not alter the terminal's top-frame.
12538 * xdisp.c (format_mode_line_unwind_data): Record the target
12539 frame's selected window and its terminal's top-frame.
12540 (unwind_format_mode_line): Restore them.
12541 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
12543 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
12544 since tty frames can be explicitly named.
12545 (prepare_menu_bars): Likewise.
12547 * term.c (Ftty_top_frame): New function.
12549 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

12552 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
12553 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
12554 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
12555 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
12556 (METER_1, METER_2): Simplify.
12558 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
12560 * data.c (Fdefalias): Return `symbol' (bug#11686).
12562 2012-06-18 Martin Rudalics <rudalics@gmx.at>
12564 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
12565 gets killed during executing of this function (Bug#11665).
12566 Try to always return Qt when the buffer has been actually killed.
12567 (Vkill_buffer_query_functions): In doc-string say that functions
12568 run by this hook should not change the current buffer.
12570 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
12572 Fix recently-introduced process.c problems found by static checking.
12573 * process.c (write_queue_push, write_queue_pop, send_process):
12574 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
12575 (write_queue_pop): Fix pointer signedness problem.
12576 (send_process): Remove unused local.
12578 2012-06-17 Chong Yidong <cyd@gnu.org>
12580 * xdisp.c (redisplay_internal): No need to redisplay terminal
12581 frames that are not on top.

12590 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
12592 * lisp.h (eassert): Assume C89 or later.
12593 This removes the need for CHECK.
12594 (CHECK): Remove. Its comments about always evaluating its
12595 argument were confusing, as 'eassert' typically does not evaluate
12598 * coding.c (produce_chars): Use ptrdiff_t, not int.
12600 * xterm.c (x_draw_underwave): Check for integer overflow.
12601 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
12603 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
12605 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
12606 referenced (Bug#11583).
12608 2012-06-16 Aurelien Aptel <aurelien.aptel@gmail.com>

12935 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12936 would mishandle a string argument "Xc" if X was a multibyte
12937 character of length 2: it would truncate after X's first byte
12938 rather than including all of X.

12991 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12992 Convert pctcpu and pctmem to Lisp float properly.
12993 Let the compiler fold better, as 100.0/0x8000 is exact.

13009 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
13010 change its type from Lisp_Object to bitfield.

13019 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
13020 Use 'float' consistently, rather than 'float' in most places
13021 and 'double' in a couple of places.
13023 2012-05-31 Eli Zaretskii <eliz@gnu.org>
13025 * xdisp.c (handle_stop): Detect whether we have overlay strings
13026 loaded by testing it->current.overlay_string_index to be
13027 non-negative, instead of checking whether n_overlay_strings is
13028 positive. (Bug#11587)

13045 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
13046 for the duration of call to load_charset, to avoid problems with

13051 decrement the inhibition flag, instead of just setting or

13056 Remove obsolete '#define static' cruft.
13057 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

13067 Clean up __executable_start, monstartup when --enable-profiling.
13068 The following changes affect the code only when profiling.
13069 * dispnew.c (__executable_start): Rename from safe_bcopy.
13070 Define only on platforms that need it.
13071 * emacs.c: Include <sys/gmon.h> when profiling.
13072 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
13073 (__executable_start): Remove decl, since lisp.h does it now.
13074 (safe_bcopy): Remove decl; no longer has that name.
13075 (main): Coalesce #if into single bit of code, for simplicity.
13076 Cast pointers to uintptr_t, since standard libraries want integers
13078 * lisp.h (__executable_start): New decl.
13080 2012-05-31 Glenn Morris <rgm@gnu.org>
13082 * image.c (Fimagemagick_types): Doc fix.
13084 2012-05-30 Jim Meyering <meyering@redhat.com>
13086 * callproc.c (Fcall_process_region): Include directory component
13087 in mkstemp error message (Bug#11586).
13089 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
13091 * alloc.c, lisp.h (make_pure_vector): Now static.
13093 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
13095 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
13096 Move to byte-run.el.
13097 (Fautoload): Do the hash-doc more carefully.
13098 * data.c (Fdefalias): Purify definition, except for keymaps.
13099 (Qdefun): Move from eval.c.
13100 * lisp.h (Qdefun): Remove.
13101 * lread.c (read1): Tiny simplification.
13103 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
13105 Do not create empty overlays with the evaporate property (Bug#9642).
13106 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
13107 Bug#9642, but explicitly check that the buffer the overlay would
13108 be moved to is live and rearrange lines to make sure that errors
13109 will not put the overlay in an inconsistent state.
13110 (Fdelete_overlay): Cosmetics.
13112 2012-05-28 Eli Zaretskii <eliz@gnu.org>
13114 * w32term.c (my_bring_window_to_top): New function.
13115 (x_raise_frame): Use handle returned by DeferWindowPos, which
13116 could be different from the original one.
13117 Call my_bring_window_to_top instead of my_set_foreground_window.
13120 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
13121 by calling BringWindowToTop.

13126 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
13128 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
13129 This avoids undefined behavior that might cause the eassert
13130 to not catch an out-of-range value.
13132 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
13134 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
13135 Update dependencies.
13137 2012-05-27 Eli Zaretskii <eliz@gnu.org>
13139 * bidi.c (bidi_mirror_char): Fix last change.
13141 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
13143 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
13144 when referring to sectname field in printf format.
13146 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
13148 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
13149 Only r_alloc_inhibit_buffer_relocation needed to be added;
13150 the others were already declared.
13152 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
13153 before checking whether it's out of range. Put the check inside
13155 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
13157 2012-05-27 Ken Brown <kbrown@cornell.edu>
13159 * callproc.c (Fcall_process): Restore a line that was accidentally
13160 commented out in the 2011-02-13 change (bug#11547).
13162 2012-05-27 Eli Zaretskii <eliz@gnu.org>
13164 * lisp.h [REL_ALLOC]: Add prototypes for external functions
13165 defined on ralloc.c.
13167 * buffer.c [REL_ALLOC]: Remove prototypes of
13168 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
13169 they are now on lisp.h.
13171 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
13173 * search.c (search_buffer): Use it to inhibit relocation of buffer
13174 text while re_search_2 is doing its job, because re_search_2 is
13175 passed C pointers to buffer text. (Bug#11519)
13177 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
13178 Update value to 24.
13180 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
13181 state after an additional call to move_it_in_display_line_to, keep
13182 the values of it->max_ascent and it->max_descent found for the
13184 (pos_visible_p): Revert the comparison against bottom_y to what it
13185 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
13188 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13190 Fix coding-related core dumps with gcc -ftrapv.
13191 The code was computing A - B, where A and B are pointers, and B is
13192 random garbage. This can lead to core dumps on platforms that
13193 have special pointer registers, and it also leads to core dumps on
13194 x86-64 when compiled with gcc -ftrapv. The fix is to compute
13195 A - B only when B is initialized properly.
13196 * coding.c (coding_set_source, coding_set_destination): Return void.
13197 (coding_change_source, coding_change_destinations): New functions,
13198 with the old behaviors of coding_set_source and coding_set_destination.
13199 All callers that need an offset changed to use these new functions.
13201 2012-05-26 Glenn Morris <rgm@gnu.org>
13203 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
13205 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13207 Extend mouse support on W32 text-mode console.
13208 * xdisp.c (draw_row_with_mouse_face):
13209 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
13211 * w32console.c: Include window.h.
13212 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
13214 (initialize_w32_display): Initialize mouse-highlight data.
13216 * w32inevt.c: Include termchar.h and window.h.
13217 (do_mouse_event): Support mouse-autoselect-window. When the mouse
13218 moves, call note_mouse_highlight. If help_echo changed, call
13219 gen_help_event to produce help-echo message in the echo area.
13220 Call clear_mouse_face if mouse_face_hidden is set in the mouse
13223 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
13225 * lread.c (read1): Simplify slightly to avoid an overflow warning
13226 with GCC 4.7.0 on x86-64.
13228 2012-05-26 Eli Zaretskii <eliz@gnu.org>
13230 * bidi.c (bidi_mirror_char): Revert last change: an int is
13231 definitely wide enough here.
13233 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
13235 Fix integer width and related bugs (Bug#9874).
13236 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
13237 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
13238 (string_bytes, check_sblock, allocate_string_data):
13239 (compact_small_strings, Fmake_bool_vector, make_string)
13240 (make_unibyte_string, make_multibyte_string)
13241 (make_string_from_bytes, make_specified_string)
13242 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
13243 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
13245 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13246 (allocate_pseudovector):
13247 Use int, not EMACS_INT, where int is wide enough.
13248 (inhibit_garbage_collection, Fgarbage_collect):
13249 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13250 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
13251 int might not be wide enough.
13252 (bidi_cache_search, bidi_cache_find, bidi_init_it)
13253 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
13254 (bidi_at_paragraph_end, bidi_find_paragraph_start)
13255 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
13256 (bidi_level_of_next_char, bidi_move_to_visually_next):
13257 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13258 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
13259 (Fkill_buffer, Fset_buffer_major_mode)
13260 (advance_to_char_boundary, Fbuffer_swap_text)
13261 (Fset_buffer_multibyte, overlays_at, overlays_in)
13262 (overlay_touches_p, struct sortvec, record_overlay_string)
13263 (overlay_strings, recenter_overlay_lists)
13264 (adjust_overlays_for_insert, adjust_overlays_for_delete)
13265 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
13266 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
13267 (Foverlay_recenter, last_overlay_modification_hooks_used)
13268 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
13269 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13270 (validate_region): Omit unnecessary test for b <= e,
13271 since that's guaranteed by the previous test.
13272 (adjust_overlays_for_delete): Avoid pos + length overflow.
13273 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
13274 (report_overlay_modification):
13275 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13276 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
13277 Omit pointer cast, which isn't needed anyway, and doesn't work
13278 after the EMACS_INT -> ptrdiff_t change.
13279 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
13280 * buffer.h: Adjust decls to match defn changes elsewhere.
13281 (struct buffer_text, struct buffer):
13282 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13283 Use EMACS_INT, not int, where int might not be wide enough.
13284 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
13285 not int, to avoid needless 32-bit limit on 64-bit hosts.
13286 (exec_byte_code): Use tighter memory-full test, one that checks
13287 for alloca overflow. Don't compute the address of the object just
13288 before an array, as that's not portable. Use EMACS_INT, not
13289 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
13290 * callint.c (Fcall_interactively):
13291 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13292 * callproc.c (call_process_kill, Fcall_process):
13293 Don't assume pid_t fits into an Emacs fixnum.
13294 (call_process_cleanup, Fcall_process, child_setup):
13295 Don't assume pid_t fits into int.
13296 (call_process_cleanup, Fcall_process, delete_temp_file)

13298 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13299 (Fcall_process): Simplify handling of volatile integers.
13300 Use int, not EMACS_INT, where int will do.
13301 * casefiddle.c (casify_object, casify_region, operate_on_word)
13302 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
13303 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13304 (casify_object): Avoid integer overflow when overallocating buffer.
13305 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
13306 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
13307 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
13308 * category.h (CATEGORYP): Don't assume arg is nonnegative.
13309 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
13310 integers are now checked earlier. All uses replaced with XINT.
13312 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13313 For CCL_MapSingle, check that content and value are in int range.
13314 (ccl_driver, Fregister_code_conversion_map):
13315 Check that Vcode_version_map_vector is a vector.
13316 (resolve_symbol_ccl_program): Check that vector header is in range.
13317 Always copy the vector, so that we can check its contents reliably
13318 now rather than having to recheck each instruction as it's being
13319 executed. Check that vector words fit in 'int'.
13320 (ccl_get_compiled_code, Fregister_ccl_program)
13321 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
13322 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
13323 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
13324 contents are in range.
13325 (Fccl_execute_on_string): Check that status is in range.
13326 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
13327 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
13328 Accept and return EMACS_INT, not int, because callers can pass values
13329 out of 'int' range.
13330 (c_string_width, strwidth, lisp_string_width, chars_in_text)
13331 (multibyte_chars_in_text, parse_str_as_multibyte)

13333 (str_as_unibyte, str_to_unibyte, string_count_byte8)
13334 (string_escape_byte8, Fget_byte):
13335 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13336 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
13337 avoid mishandling large integers.
13338 * character.h: Adjust decls to match defn changes elsewhere.
13339 * charset.c (load_charset_map_from_file, find_charsets_in_text)
13340 (Ffind_charset_region):
13341 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13342 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
13343 (load_charset_map_from_vector, Fdefine_charset_internal):
13344 Don't assume fixnum fits in int.
13345 (load_charset_map_from_vector, Fmap_charset_chars):
13346 Remove now-unnecessary CHECK_NATNUMs.
13347 (Fdefine_charset_internal): Check ranges here, more carefully.
13348 Don't rely on undefined behavior with signed left shift overflow.
13349 Don't assume unsigned int fits into fixnum, or that fixnum fits
13350 into unsigned int. Don't require max_code to be a valid fixnum;
13351 that's not true for gb10830 4-byte on a 32-bit host. Allow
13352 invalid_code to be a cons, for the same reason. Require code_offset
13353 to be a character. Avoid int overflow if max_char is close
13355 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
13356 this is intended anyway and avoids some undefined behavior.
13357 (load_charset_map): Pass unsigned, not int, as 2nd arg of
13358 INDEX_TO_CODE_POINT, as that's what it expects.
13359 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
13360 * charset.h (DECODE_CHAR): Return int, not unsigned;
13361 this is what was intended anyway, and it avoids undefined behavior.
13362 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
13363 integer-overflow issues.
13364 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
13365 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
13366 where the argument is EMACS_INT, and this behavior is not intended.
13367 * chartab.c (Fmake_char_table, Fset_char_table_range)
13368 (uniprop_get_decoder, uniprop_get_encoder):
13369 Don't assume fixnum fits in int.
13370 * cmds.c (move_point): New function, that does the gist of
13371 Fforward_char and Fbackward_char, but does so while checking
13372 for integer overflow more accurately.
13373 (Fforward_char, Fbackward_char): Use it.
13374 (Fforward_line, Fend_of_line, internal_self_insert)
13375 (internal_self_insert):
13376 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13377 Fix a FIXME, by checking for integer overflow when calculating
13378 target_clm and actual_clm.

13410 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13411 (consume_chars): Rewrite to not calculate an address outside buffer.
13412 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
13413 Don't access memory outside of the args array.
13414 (Fdefine_coding_system_internal): Check for charset-id overflow.
13415 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
13416 result of ENCODE_CHAR.
13417 * coding.h: Adjust decls to match defn changes elsewhere.
13418 (struct coding_system):
13419 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

13429 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

13433 (struct composition):
13434 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13435 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
13436 Do not attempt to compute the address of the object just before a
13437 buffer; this is not portable.
13439 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
13440 (Faset): Use int, not EMACS_INT, where int is wide enough.
13441 (Fstring_to_number): Don't assume fixnums fit in int.

14136 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
14138 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
14139 reference to image_cache->refcount.
14140 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
14142 2012-05-17 Juri Linkov <juri@jurta.org>
14144 * search.c (Fword_search_regexp, Fword_search_backward)
14145 (Fword_search_forward, Fword_search_backward_lax)
14146 (Fword_search_forward_lax): Move functions to isearch.el
14147 (bug#10145, bug#11381).
14149 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
14151 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
14153 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
14155 * lread.c (init_obarray): Declare Qt and Qnil as special.
14157 2012-05-14 Glenn Morris <rgm@gnu.org>
14159 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
14160 Put "libexec" before "bin", for the sake of init_callproc_1.
14162 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14164 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
14166 * unexaix.c: Port to more-recent AIX compilers.
14167 (report_error, report_error_1, make_hdr, copy_sym)
14168 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
14169 Make arguments const char *, not char *, to avoid violations of C
14170 standard and to fix some AIX warnings reported by Gilles Pion.
14172 2012-05-14 Eli Zaretskii <eliz@gnu.org>
14174 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
14175 already have overlays loaded.
14176 (handle_single_display_spec): Before returning without displaying
14177 fringe bitmap, synchronize the bidi iterator with the main display
14178 iterator, by calling iterate_out_of_display_property.
14179 (iterate_out_of_display_property): Detect buffer iteration by
14180 testing that it->string is a Lisp string.
14181 (get_next_display_element): When the current object is exhausted,
14182 and there's something on it->stack, call set_iterator_to_next to
14183 proceed with what's on the stack, instead of returning zero.
14184 (set_iterator_to_next): If called at the end of a Lisp string,
14185 proceed to consider_string_end without incrementing string
14186 position. Don't increment display vector index past the end of
14187 the display vector. (Bug#11417)
14188 (pos_visible_p): Don't report a position visible when move_it_to
14189 stopped at the last line of window, which happens to be scanned
14190 backwards by the bidi iteration. (Bug#11464)
14192 2012-05-14 Eli Zaretskii <eliz@gnu.org>
14194 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
14195 and right-margin display specs even if the spec is invalid or we
14196 are on a TTY, and thus unable to display on the fringes.
14197 That's because the text with the property will not be displayed anyway,
14198 so we need to signal to the caller that this is a "replacing"
14199 display spec. This fixes display when the spec is invalid or we
14202 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
14204 * unexaix.c (make_hdr): Fix typo in prototype.
14205 This bug broke the build on AIX. Problem reported by Gilles Pion.
14207 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
14209 * keyboard.c (kbd_buffer_get_event): Read special events also in
14210 batch mode. (Bug#11415)
14212 2012-05-12 Glenn Morris <rgm@gnu.org>
14214 * ns.mk: Update for ns_appbindir no longer having trailing "/".
14216 2012-05-12 Eli Zaretskii <eliz@gnu.org>
14218 * lisp.mk (lisp): Add newcomment.elc.
14220 2012-05-12 Glenn Morris <rgm@gnu.org>
14222 * Makefile.in (MKDIR_P): New, set by configure.
14223 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
14225 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
14227 Remove unused function hourglass_started.
14228 * dispextern.h (hourglass_started):
14229 * w32fns.c (hourglass_started):
14230 * xdisp.c (hourglass_started): Remove.
14232 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
14234 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
14235 Update dependencies.
14237 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
14239 * xgselect.c (xg_select): Put maxfds+1 into a var.
14240 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
14242 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
14244 2012-05-10 Dave Abrahams <dave@boostpro.com>
14246 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
14247 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
14249 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
14251 * dbusbind.c (xd_registered_buses): New internal Lisp object.
14252 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
14253 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
14254 Initialize xd_registered_buses.
14256 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
14258 Untag more efficiently if USE_LSB_TAG.
14259 This is based on a proposal by YAMAMOTO Mitsuharu in
14260 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
14261 For an admittedly artificial (nth 8000 longlist) benchmark on
14262 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
14263 Emacs's overall text size by 1%.
14264 * lisp.h (XUNTAG): New macro.
14265 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
14266 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
14267 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
14268 * eval.c (Fautoload):
14269 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
14270 * frame.h (XFRAME): Use XUNTAG.
14272 Port recent dbusbind.c changes to 32-bit --with-wide-int.
14273 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
14274 Remove unportable assumptions about print widths of types like
14276 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
14277 intptr_t when converting between pointer and integer, to avoid GCC
14278 warnings about wrong width.
14280 2012-05-09 Eli Zaretskii <eliz@gnu.org>
14282 * w32proc.c (new_child): Force Windows to reserve only 64KB of
14283 stack for each reader_thread, instead of defaulting to 8MB
14284 determined by the linker. This avoids failures in creating
14285 subprocesses on Windows 7, see the discussion in this thread:
14286 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
14288 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
14290 Fix up display of the *Minibuf-0* buffer in the mini window.
14291 * keyboard.c (read_char): Don't clear the echo area if there's no
14293 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
14294 contents of *Minibuf-0*) if there's no message displayed in its stead.
14296 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
14298 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
14301 2012-05-06 Chong Yidong <cyd@gnu.org>
14303 * lisp.mk (lisp): Update.
14305 2012-05-05 Jim Meyering <meyering@redhat.com>
14307 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
14309 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
14311 * data.c (PUT_ERROR): New macro.
14312 (syms_of_data): Use it. Add new error type `user-error'.
14313 * undo.c (user_error): New function.
14314 (Fprimitive_undo): Use it.
14315 * print.c (print_error_message): Adjust print style for `user-error'.
14316 * keyboard.c (user_error): New function.
14317 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
14319 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
14321 Do not limit current-time-string to years 1000..9999.
14322 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
14323 (Fcurrent_time_string): Support any year that is supported by the
14324 underlying localtime representation. Don't use asctime, as it
14325 has undefined behavior for years outside the range -999..9999.
14327 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
14329 Fix race conditions involving setenv, gmtime, localtime, asctime.
14330 Without this fix, interrupts could mess up code that uses these
14331 nonreentrant functions, since setting TZ invalidates existing
14332 tm_zone or tzname values, and since most of these functions return
14333 pointers to static storage.
14334 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
14335 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
14336 Grow the critical sections to include not just invoking
14337 localtime/gmtime, but also accessing these functions' results
14338 including their tm_zone values if any, and any related TZ setting.
14339 (format_time_string): Last arg is now struct tm *, not struct tm **,
14340 so that the struct tm is saved in the critical section.
14341 All callers changed. Simplify allocation of initial buffer, partly
14342 motivated by the fact that memory allocation needs to be outside
14343 the critical section.
14345 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
14347 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
14348 with RESET_INTERVAL.
14350 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
14351 Remove duplicated buffer name initialization.
14353 2012-05-02 Jim Meyering <jim@meyering.net>
14355 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
14357 * xfns.c (x_window): Use xstrdup (Bug#11375).
14359 2012-05-02 Eli Zaretskii <eliz@gnu.org>
14361 * xdisp.c (pos_visible_p): If already at a newline from the
14362 display string before the 'while' loop, don't walk back the glyphs
14363 from it3.glyph_row. Solves assertion violation when the display
14364 string begins with a newline (egg.el). (Bug#11367)
14366 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
14368 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
14371 2012-05-01 Glenn Morris <rgm@gnu.org>
14373 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
14374 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
14375 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
14376 All were removed before 23.1.
14378 * dispnew.c: Remove HAVE_LIBNCURSES test;
14379 it is always true on relevant platforms.
14381 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
14382 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
14384 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
14386 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
14388 * .gdbinit (xpr): Remove checks for no longer existing misc types.
14389 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
14392 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
14394 Do not avoid creating empty evaporating overlays (Bug#9642).
14395 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
14396 That is, do not delete an evaporating overlay if it becomes
14397 empty after its bounds are adjusted to fit within its buffer.
14398 This fix caused other problems, and I'm reverting it until we get
14399 to the bottom of them.
14401 2012-04-27 Chong Yidong <cyd@gnu.org>
14403 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
14405 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14407 * xdisp.c (pos_visible_p): If the window start position is beyond
14408 ZV, start the display from buffer beginning. Prevents assertion
14409 violation in init_iterator when the minibuffer window is scrolled
14410 via the scroll bar.
14412 * window.c (window_scroll_pixel_based): Likewise.
14414 2012-04-27 Chong Yidong <cyd@gnu.org>
14416 * keymap.c (where_is_internal): Doc fix (Bug#10872).
14418 2012-04-27 Glenn Morris <rgm@gnu.org>
14420 * fileio.c (Fcopy_file, Fset_file_selinux_context):
14421 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
14423 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14425 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
14426 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
14428 2012-04-26 Eli Zaretskii <eliz@gnu.org>
14430 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
14431 display element, check also the underlying string or buffer
14432 character. (Bug#11341)
14434 * w32menu.c: Include w32heap.h.
14435 (add_menu_item): If the call to AppendMenuW (via
14436 unicode_append_menu) fails, disable Unicode menus only if we are
14437 running on Windows 9X/Me.
14439 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
14441 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
14442 (xgetint): Add missing shift for LSB tags.
14444 2012-04-24 Martin Rudalics <rudalics@gmx.at>
14446 * keyboard.c (read_char): Don't wipe echo area for select window
14447 events: These might get delayed via `mouse-autoselect-window'
14450 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
14452 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
14453 manipulation of :loaded-from data.
14455 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
14457 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
14458 now a cons (bug#11311).
14460 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
14462 Do not create empty overlays with the evaporate property (Bug#9642).
14463 * buffer.c (Fmove_overlay): Delete an evaporating overlay
14464 if it becomes empty after its bounds are adjusted to fit within
14465 its buffer. Without this fix, in a nonempty buffer (let ((o
14466 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
14467 yields an empty overlay that has the evaporate property, which is
14468 not supposed to happen.
14470 Fix minor GTK3 problems found by static checking.
14471 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14472 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14473 (struct _EmacsFixedClass, emacs_fixed_get_type):
14474 Move decls here from emacsgtkfixed.h, since they needn't be public.
14475 (emacs_fixed_get_type): Now static.
14476 (emacs_fixed_class_init): Omit unused local.
14477 (emacs_fixed_child_type): Remove; unused.

14479 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14480 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
14481 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
14482 (EMACS_FIXED_GET_CLASS): Remove; unused.
14483 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
14485 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
14486 Problem reported by Juanma Barranquero for Windows -Wunused-function.
14488 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14490 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
14491 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
14492 (__malloc_size_t, __malloc_ptrdiff_t):
14493 Remove. All uses removed, replaced by the definiens if needed,
14494 since we can assume C89 or better now.
14495 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

14503 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
14504 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
14505 Define using prototypes, not old style.
14506 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
14507 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
14508 (align): Don't assume that signed integer overflow wraps around.
14509 Omit unused local var.
14510 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
14511 (_free_internal_nolock, memalign, mallochook, reallochook):
14512 Omit no-longer-needed casts.
14513 (valloc): Use getpagesize, not __getpagesize.
14514 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
14515 (struct hdr): The 'magic' member is now size_t, not unsigned long.
14517 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
14519 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
14521 Move functions from C to Lisp. Make non-blocking method calls
14522 the default. Implement further D-Bus standard interfaces.
14524 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

14583 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14585 * sysdep.c [__FreeBSD__]: Minor cleanups.
14586 (list_system_processes, system_process_attributes) [__FreeBSD__]:
14587 Use Emacs indenting style more consistently. Avoid some casts.

14606 * print.c (print_preprocess): Only check print_depth if print-circle
14608 (print_object): Check for cycles even when print-circle is nil and
14609 print-gensym is t, but only check print_depth if print-circle is nil.

14613 * process.c (wait_reading_process_output): If EIO occurs on a pty,
14614 set the status to "failed" and ensure that sentinel is run.
14616 2012-04-20 Glenn Morris <rgm@gnu.org>
14618 * process.c (Fset_process_inherit_coding_system_flag)
14619 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

14629 farther than the first row after the header line, if any.
14630 Don't consider the header-line row as "partially visible", even if
14631 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
14633 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

14643 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
14644 (ALL_CFLAGS): Use new macros rather than old.
14645 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.

14647 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
14648 -Wunused-result, -Wunused-variable. This should go away once
14649 the Emacs and Gnulib regex code is merged.
14650 (xmalloc, xrealloc): Now static.
14652 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

14669 New extern decls, to avoid calling undeclared functions.
14670 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
14671 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
14672 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14673 (NEED_MEM_INSERT): New macro.
14674 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14675 Remove one incorrect comment and fix another.

14690 Remove decls. This fixes an "It stinks!".
14692 * alloc.c (which_symbols): Fix alignment issue / type clash.
14694 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
14696 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
14697 (struct Lisp_Misc_Any): Likewise.
14698 (struct Lisp_Free): Likewise.
14699 * alloc.c (union aligned_Lisp_Symbol): Define.

14710 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
14711 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14712 * s/netbsd.h, s/sol2-6.h:
14713 Remove definition of GC_MARK_STACK, since the default now works.
14714 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

14716 no longer the default.
14717 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14719 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
14721 * lread.c (lisp_file_lexically_bound_p):

14724 2012-04-14 Eli Zaretskii <eliz@gnu.org>
14726 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
14727 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

14740 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
14742 2012-04-11 Daniel Colascione <dancol@dancol.org>
14744 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14745 against is gone. It's better to use vfork now so that when Cygwin
14746 gains a new, working vfork, we use it automatically (bug#10398).
14748 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

14768 * w32.c (w32_delayed_load): Record the full path of the library
14769 being loaded (bug#10424).
14771 2012-04-09 Glenn Morris <rgm@gnu.org>
14773 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14774 not just in the obarray, before snarfing them. (Bug#11036)

14791 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14792 attempts per process (connection).
14794 2012-04-09 Chong Yidong <cyd@gnu.org>
14796 * eval.c (Fuser_variable_p, user_variable_p_eh)

14798 (Fdefvar): Caller changed.
14800 * callint.c (Finteractive, Fcall_interactively):
14801 * minibuf.c (Fread_variable): Callers changed.
14803 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14805 * xdisp.c (set_cursor_from_row): If the display string appears in
14806 the buffer at position that is closer to point than the position
14807 after the display string, display the cursor on the first glyph of
14808 the display string. Fixes cursor display when a 'display' text
14809 property immediately follows invisible text. (Bug#11094)
14811 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14813 composite.c: use 'double' consistently
14814 * composite.c (get_composition_id): Use 'double' consistently
14815 instead of converting 'float' to 'double' and vice versa; this is
14816 easier to understand and avoids a GCC warning.
14818 2012-04-09 Glenn Morris <rgm@gnu.org>
14820 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14821 preparation for dumping it with emacs. (Bug#4789)

14843 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14844 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14845 objects, as mark_maybe_pointer will catch them otherwise.

14863 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14864 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14865 [!WINDOWSNT]: New macros.
14866 (init_libxml2_functions, libxml2_loaded_p): New functions.
14867 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14868 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14869 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14870 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14872 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14873 Call init_libxml2_functions before calling libxml2 functions.
14874 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14876 * emacs.c: Don't include libxml/parser.h.

14882 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14884 * indent.c (Fvertical_motion): If there is a display string at
14885 point, use it.vpos to compute how many lines to backtrack after
14886 move_it_to point. (Bug#11133)
14888 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14890 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14891 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14892 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14893 macros related to unification of CJK characters. For the details,
14894 see the discussion following the message here:
14895 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14897 2012-04-04 Chong Yidong <cyd@gnu.org>
14899 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14901 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14903 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

14911 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14913 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14914 position we get to after a call to move_it_to fails the
14915 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14916 only if we wind up in a string from display property. (Bug#11063)
14918 * window.c (Fdelete_other_windows_internal): Invalidate the row
14919 and column information about mouse highlight, so that redisplay
14920 restores it after reallocating the glyph matrices. (Bug#7464)
14922 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14923 string comes from a `display' text property, use the buffer
14924 position of that property as if we actually saw that position in
14926 (move_it_by_lines): Remove the assertion that
14927 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14928 violated when there's a before-string at the beginning of a line.
14931 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14933 * xdisp.c (append_space_for_newline): If the default face was

14936 extending the face to the end of the line.
14937 (display_line): Call extend_face_to_end_of_line when the default
14938 face was remapped. (Bug#11068)

14960 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14961 (command_loop_1): Use it; inhibit selection update for

14966 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14968 2012-03-25 Kenichi Handa <handa@m17n.org>
14970 * dispextern.h (struct glyph): Change the bit length of
14971 glyphless.ch to 22 to make the member glyphless fit in 32 bits.

14986 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14988 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14989 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14990 when fetching a multibyte character consumes more bytes than
14991 CHAR_BYTES returns, due to unification of CJK characters in
14992 string_char. (Bug#11073)
14994 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14996 * process.c (wait_reading_process_output): Handle pty disconnect
14997 by refraining from sending oneself a SIGCHLD (bug#10933).
14999 2012-03-22 Chong Yidong <cyd@gnu.org>
15001 * dispextern.h (struct it): New member string_from_prefix_prop_p.
15003 * xdisp.c (push_prefix_prop): Rename from push_display_prop.

15028 2012-03-18 Eli Zaretskii <eliz@gnu.org>
15030 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
15031 that is not from display property, accept the row as a "cursor
15032 row" if one of the string's character has a non-nil `cursor'
15033 property. Fixes cursor positioning when there are newlines in
15034 overlay strings, e.g. in icomplete.el. (Bug#11035)
15036 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
15038 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

15067 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
15070 2012-03-03 Glenn Morris <rgm@gnu.org>
15072 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
15074 2012-03-02 Eli Zaretskii <eliz@gnu.org>

15077 position past the first glyph_row that ends at ZV. (Bug#10902)
15078 (redisplay_window, next_element_from_string): Fix typos in
15080 (redisplay_window): Pass to move_it_vertically the margin in
15081 pixels, not in screen lines.
15083 2012-03-02 Glenn Morris <rgm@gnu.org>
15085 * buffer.c (buffer-list-update-hook): Doc fix.
15087 2012-02-29 Eli Zaretskii <eliz@gnu.org>
15089 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
15090 push_it before setting up the iterator for the first overlay
15091 string, even if we have an empty string loaded.
15092 (next_overlay_string): If there's an empty string on the iterator
15093 stack, pop the stack. (Bug#10903)
15095 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
15097 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
15098 Suggested by Stefan Monnier in
15099 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
15100 * alloc.c (widen_to_Lisp_Object): New static function.
15101 (mark_memory): Also mark Lisp_Objects by fetching pointer words
15102 and widening them to Lisp_Objects. This would work even if
15103 USE_LSB_TAG is defined and wide integers are used, which might
15104 happen in a future version of Emacs.
15106 2012-02-25 Chong Yidong <cyd@gnu.org>
15108 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

15113 before saving to clipboard manager.
15115 2012-02-24 Chong Yidong <cyd@gnu.org>
15117 * keyboard.c (process_special_events): Handle all X selection
15118 requests in kbd_buffer, not just the next one (Bug#8869).
15120 2012-02-23 Chong Yidong <cyd@gnu.org>
15122 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
15123 call when setting menu-bar-lines and tool-bar-lines parameters.
15124 (unwind_create_frame_1): New helper function.
15126 * window.c (inhibit_window_configuration_change_hook): New var.
15127 (run_window_configuration_change_hook): Obey it.

15145 when computing $valmask.
15147 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
15148 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
15149 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
15150 It's useless in that case, and it can cause problems on hosts
15151 that allocate halves of EMACS_INT values separately.
15152 Reported by Dan Horák. Diagnosed by Andreas Schwab in
15153 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
15154 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
15155 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
15156 it avoids undefined behavior on hosts where shifting right by more
15157 than the word width has undefined behavior.
15159 2012-02-19 Chong Yidong <cyd@gnu.org>
15161 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
15162 (Funhandled_file_name_directory, Ffile_name_as_directory)
15163 (Fdirectory_file_name, Fexpand_file_name)
15164 (Fsubstitute_in_file_name): Protect against invalid file handler
15165 return values (Bug#10845).

15179 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
15181 2012-02-15 Chong Yidong <cyd@gnu.org>
15183 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
15184 marked as special. Also, starting docstrings with * is obsolete.

15199 2012-02-12 Chong Yidong <cyd@gnu.org>
15201 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
15202 as that creates a dangerous corner case.
15204 * window.c (Fdelete_window_internal): Invalidate the mouse
15205 highlight (Bug#9904).
15207 2012-02-12 Glenn Morris <rgm@gnu.org>

15212 * nsselect.m (Fx_own_selection_internal)
15213 (Fx_disown_selection_internal, Fx_selection_exists_p)
15214 (Fx_selection_owner_p, Fx_get_selection_internal):
15215 Sync docs and argument specs with the xselect.c versions.
15217 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

15237 2012-02-07 Chong Yidong <cyd@gnu.org>
15239 * buffer.c (Fbuffer_local_variables)
15240 (buffer_lisp_local_variables): Handle unbound vars correctly;
15241 don't let Qunbound leak into Lisp.
15243 2012-02-07 Glenn Morris <rgm@gnu.org>
15245 * image.c (Fimagemagick_types): Doc fix.
15247 * image.c (imagemagick-render-type): Change it from a lisp object
15248 to an integer. Move the doc here from the lisp manual.

15265 2012-02-04 Eli Zaretskii <eliz@gnu.org>
15267 * w32.c (get_emacs_configuration_options):
15268 Include --enable-checking, if specified, in the return value.

15278 before BEGV. (Bug#10696)
15280 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
15282 Handle overflow when computing char display width (Bug#9496).
15283 * character.c (char_width): Return EMACS_INT, not int.
15284 (char_width, c_string_width): Check for overflow when
15285 computing the width; this is possible now that individual
15286 characters can have unbounded width. Problem introduced
15287 by merge from Emacs 23 on 2012-01-19.

15311 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
15313 (x_produce_glyphs): If the component of a composition is a null

15318 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
15319 first 2 arguments are identical. This makes inserting large
15320 output from a subprocess an order of magnitude faster on
15321 MS-Windows, where all sbrk'ed memory is always contiguous.
15323 2012-01-31 Glenn Morris <rgm@gnu.org>

15420 * xdisp.c (rows_from_pos_range): Accept additional argument
15421 DISP_STRING, and accept any glyph in a row whose object is that
15422 string as eligible for mouse highlight. Fixes mouse highlight of
15423 display strings from overlays. (Bug#10464)
15425 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
15427 emacs: fix an auto-save permissions race condition (Bug#10400)

15429 (Fmake_directory_internal): Use it.
15430 (do_auto_save_make_dir): Set it, instead of invoking chmod after

15434 (Fdo_auto_save): Catch all errors, not just file errors, so
15435 that the var is always cleared.

15940 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15941 is set, removing the need for VIRT_ADDRESS_VARIES.
15942 (PURE_P): Use a more-efficient implementation that needs just one

15945 to 4 (xorl, subq, cmpq, setbe).
15946 * alloc.c (pure): Always extern now, since that's the

15957 (erase_phys_cursor, update_window_cursor, show_mouse_face)
15958 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
15959 behave as if the cursor position were at the window margin.
15961 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15962 and the cursor position is out of bounds, behave as if the cursor
15963 position were at the window margin. (Bug#10075)
15965 2011-11-18 Chong Yidong <cyd@gnu.org>
15967 * window.c (Fwindow_combination_limit): Make first argument

16436 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
16438 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
16439 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
16440 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
16441 (Fmove_to_window_line): Doc fix.
16443 2011-10-27 Chong Yidong <cyd@gnu.org>
16445 * process.c (make_process): Set gnutls_state to NULL.
16447 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
16448 non-NULL, regardless of GNUTLS_INITSTAGE.
16449 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
16450 an error. Set process slots as soon as we allocate them.
16452 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
16454 2011-10-27 Chong Yidong <cyd@gnu.org>
16456 * gnutls.c (emacs_gnutls_deinit): New function.
16457 Deallocate credentials structures as well as calling gnutls_deinit.
16458 (Fgnutls_deinit, Fgnutls_boot): Use it.
16460 * process.c (make_process): Initialize GnuTLS credentials to NULL.
16461 (deactivate_process): Call emacs_gnutls_deinit.
16463 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
16465 * image.c (x_create_x_image_and_pixmap):
16466 * w32.c (sys_rename, w32_delayed_load):
16467 * w32font.c (fill_in_logfont):
16468 * w32reg.c (x_get_string_resource): Silence compiler warnings.
16470 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
16472 * w32fns.c (w32_default_color_map): New function,
16473 extracted from Fw32_default_color_map.
16474 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
16476 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
16478 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
16480 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
16482 * keyboard.c (test_undefined): New function (bug#9751).
16483 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
16485 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
16487 * sysdep.c (init_sys_modes): Fix the check for the controlling
16488 terminal (Bug#6649).
16490 2011-10-20 Eli Zaretskii <eliz@gnu.org>
16492 * dispextern.h (struct bidi_it): New member next_en_type.
16494 * bidi.c (bidi_line_init): Initialize the next_en_type member.
16495 (bidi_resolve_explicit_1): When next_en_pos is valid for the
16496 current character, check also for next_en_type being WEAK_EN.
16497 (bidi_resolve_weak): Don't enter the expensive loop if the current
16498 position is before next_en_pos. Record the bidi type of the first
16499 non-ET, non-BN character we find, in addition to its position.
16500 (bidi_level_of_next_char): Invalidate next_en_type when
16501 next_en_pos is over-stepped.
16503 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
16505 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
16506 * editfns.c: Rewrite current-time-zone so that it invokes
16507 the equivalent of (format-time-string "%Z") to get the time zone name.
16508 This fixes a bug when the time zone name contains characters that
16509 need converting from the system time locale to Emacs internal format.
16510 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
16511 that patch fixed format-time-string to do the conversion, but
16512 I forgot to fix current-time-zone.
16513 (format_time_string): New function, containing most of
16514 what Fformat_time_string used to contain.
16515 (Fformat_time_string): Rewrite in terms of format_time_string.
16516 This doesn't change this function's behavior.
16517 (current-time-zone): Rewrite to use format_time_string.
16518 This fixes the bug reported by Michael Schierl in
16519 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
16520 Jason Rumney's 2007-06-07 change worked around this bug, but
16522 * systime.h (tzname, timezone): Remove no-longer-used declarations.
16524 2011-10-19 Eli Zaretskii <eliz@gnu.org>
16526 * xdisp.c (start_display): If the character at POS is displayed
16527 via a display vector, reset IT->current.dpvec_index to zero.
16528 (try_window_reusing_current_matrix): If a line ends in a display
16529 vector or the next line starts in a display vector, continue
16530 redrawing the window even though the character position of
16531 start_row was reached.
16534 2011-10-18 Chong Yidong <cyd@gnu.org>
16536 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
16537 with nobreak-char-display too.
16539 2011-10-18 Eli Zaretskii <eliz@gnu.org>
16541 Fix part 3 of bug#9771.
16542 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
16543 (bidi_resolve_neutral): Don't enter the expensive loop looking for
16544 non-neutral characters if the current character is a paragraph
16545 separator (a.k.a. Newline). This avoids running the same
16546 expensive loop twice, once when we consume the preceding newline
16547 and the other time when the line actually needs to be displayed.
16548 Avoid the loop when we see neutrals on the base embedding level
16549 following a character whose directionality is the same as the
16550 paragraph's. This avoids running the expensive loop when a line
16551 ends in a long sequence of neutrals, like control characters.
16552 Add assertion against STRONG_AL type. Slightly rearrange code
16553 that determines the type of a neutral given the first non-neutral
16555 (bidi_level_of_next_char): Set next_en_pos to zero when
16556 invalidating its info.
16558 2011-10-17 Eli Zaretskii <eliz@gnu.org>
16560 * xdisp.c (push_display_prop): Determine whether to record string
16561 or buffer position by IT->string, not by IT->method. Allow
16562 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
16563 (move_it_vertically_backward): Don't look for character position
16564 immediately after the newline when in a continuation line.
16567 2011-10-15 Martin Rudalics <rudalics@gmx.at>
16569 * window.c (coordinates_in_window): Rewrite and delabelize
16570 vertical border check. (Bug#5357) (Bug#9618)
16572 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
16574 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
16575 errors in XSetWindowBorder (bug#9310).
16577 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
16579 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
16580 avoid crash when xmalloc overrun checking is enabled.
16582 2011-10-13 Eli Zaretskii <eliz@gnu.org>
16584 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
16585 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
16586 cursor motion with <left> and <right> arrow keys.
16588 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
16589 some callers set that themselves.
16591 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16593 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
16594 display string and the previous row comes from the same string and
16595 is empty. (Bug#9739) (Bug#9738)
16597 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
16599 * doc.c (get_doc_string): Encode file name (bug#9735).
16601 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16603 * bidi.c (bidi_level_of_next_char):
16604 * xdisp.c (get_visually_first_element): Remove old incorrect
16605 comments regarding the Unicode Line Separator character.
16607 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
16609 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
16611 * alloc.c (Fgc_status): Do not access beyond zombies array
16612 boundary if nzombies > MAX_ZOMBIES.
16613 * alloc.c (dump_zombies): Add missing format specifier.
16615 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16617 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16618 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16620 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16621 Some packages use them to denote characters with modifiers.
16623 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16625 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16626 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16627 matching a pp-number. Rename parameter var to var1.
16629 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16631 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16633 2011-10-08 Glenn Morris <rgm@gnu.org>
16635 * callint.c (Fcall_interactively): Give a more explicit error for the
16636 'c' case with a non-character input. (Bug#8479)
16638 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16640 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16642 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16643 lines that are hscrolled on the left.
16645 * dispnew.c (buffer_posn_from_coords): Account for a possible
16646 presence of header-line. (Bug#4426)
16648 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16650 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16651 Don't advertise functionality which we discourage or doesn't work.
16653 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16655 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16656 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16657 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16658 this makes Emacs dump core during garbage collection on rare
16659 occasions. sizeof is obviously inferior to offsetof here, so
16660 stick with offsetof.
16661 (GC_POINTER_ALIGNMENT): New macro.
16662 (mark_memory): Omit 3rd (offset) arg; caller changed.
16663 Don't assume EMACS_INT alignment is the same as pointer alignment.
16665 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16667 * keyboard.c (read_key_sequence_remapped): New var.
16668 (read_key_sequence): Compute remapping in the right buffer.
16669 (command_loop_1): Use read_key_sequence's remapping directly.
16671 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16673 * dired.c (file_name_completion): Don't expand file name.
16674 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16675 before checking file name handler.
16677 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16678 they've been requested explicitly (bug#9591).
16680 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16682 * keymap.c (Fsingle_key_description): Use make_specified_string
16683 instead of build_string to build string from push_key_description.
16686 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16688 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16689 This fixes a Y2038 bug on 64-bit hosts.
16690 * buffer.c (reset_buffer):
16691 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16692 (Fclear_buffer_auto_save_failure):
16693 Use 0, not -1, to represent an unset failure time, since time_t
16694 might not be signed.
16696 Remove dependency on glibc malloc internals.
16697 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16698 Move back here from lisp.h, but with their new implementations.
16699 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16700 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16701 * charset.c (charset_table_init): New static var.
16702 (syms_of_charset): Use it instead of xmalloc. This removes a
16703 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16704 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16705 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16706 Move back to alloc.c.
16707 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16708 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16710 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16712 * nsterm.m (windowDidResize): Call x_set_window_size only when
16713 ns_in_resize is true. Otherwise set pixelwidth/height and
16714 call change_frame_size (Bug#9628).
16716 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16718 Port --enable-checking=all to Fedora 14 x86-64.
16719 * charset.c (syms_of_charset): Also account for glibc malloc's
16720 internal overhead when calculating the initial malloc maximum.
16722 Port --enable-checking=all to Fedora 14 x86.
16723 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16725 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16726 (overrun_check_realloc, overrun_check_free):
16727 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16728 That way, xmalloc returns a properly-aligned pointer even if
16729 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16730 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16731 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16732 into account when calculating the initial malloc maximum.
16733 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16734 Move here from alloc.c, so that charset.c can use it too.
16735 Properly align; the old code wasn't right for common 32-bit hosts
16736 when configured with --enable-checking=all.
16737 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16738 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16740 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16742 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16745 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16747 * xdisp.c (compute_display_string_end): If there's no display
16748 string at CHARPOS, return -1.
16750 * bidi.c (bidi_fetch_char): When compute_display_string_end
16751 returns a negative value, treat the character as a normal
16752 character not covered by a display string. (Bug#9624)
16754 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16756 * lread.c (Fread_from_string): Fix typo in docstring.
16758 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16760 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16761 newline, reseat the iterator instead of bidi-iterating there one
16762 character at a time. (Bug#9610)
16763 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16764 TO_CHARPOS if the bidi iterator is at base embedding level.
16766 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16768 * lread.c (readevalloop): Use correct code for NBSP.
16769 (read1): Likewise. (Bug#9608)
16771 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16773 * dbusbind.c (Fdbus_register_signal): When service is not
16774 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16776 2011-09-25 Glenn Morris <rgm@gnu.org>
16778 * buffer.c (truncate-lines): Doc fix.
16780 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16782 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16783 (Fset_window_next_buffers): Doc fix.
16785 2011-09-24 Glenn Morris <rgm@gnu.org>
16787 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16789 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16791 Fix minor problems found by static checking.
16792 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16793 * indent.c (Fvertical_motion): Fix == vs = typo.
16795 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16797 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16798 Default value is now t. Doc fix.
16800 * indent.c (Fvertical_motion): Compute and apply the overshoot
16801 logic when moving up, not only when moving down. Fix the
16802 confusing name and values of the it_overshoot_expected variable;
16803 logic changes accordingly. (Bug#9254) (Bug#9549)
16805 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16806 CHARPOS is covered by a display string which includes newlines.
16807 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16808 is covered by a display string with embedded newlines.
16810 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16812 * dbusbind.c (Fdbus_register_signal): Add match rule to
16813 Vdbus_registered_objects_table. (Bug#9581)
16814 (Fdbus_register_method, Vdbus_registered_objects_table):
16817 2011-09-24 Jim Meyering <meyering@redhat.com>
16819 do not ignore write error for any output size
16820 The previous change was incomplete.
16821 While it makes emacs --batch detect the vast majority of stdout
16822 write failures, errors were still ignored whenever the output size is
16823 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16824 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16825 && echo FAIL: ignored write error
16826 FAIL: ignored write error
16827 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16828 && echo FAIL: ignored write error
16829 FAIL: ignored write error
16830 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16832 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16834 * emacs.c (Fkill_emacs): In noninteractive mode exit
16835 non-successfully if a write error occurred on stdout. (Bug#9574)
16837 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16839 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16842 * dispextern.h (struct it): Update the comment documenting what
16845 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16847 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16848 a display string, extend search for cursor position to end of row.
16849 (find_row_edges): If the row ends in a newline from a display
16850 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16851 Handle the case of a display string with multiple newlines.
16852 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16853 non-empty line. Fixes confusing cursor motion with arrow keys at
16854 the beginning of a line that starts with whitespace.
16856 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16858 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16861 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16863 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16864 boolean (Bug#9154).
16866 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16868 * xdisp.c (display_line): Record maximum and minimum buffer
16869 positions even if no glyphs were produced (e.g., by a zero-width
16870 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16871 buffer positions that will be removed from the glyph row because
16873 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16874 column is beyond frame width: don't subtract 1 "pixel" when
16875 computing width of the stretch.
16876 (reseat_at_next_visible_line_start): Undo the change made on
16877 2011-09-17 that saved paragraph information and restored it after
16878 the call to `reseat'. (Bug#9545)
16880 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16882 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16883 and turn window cursor on if cleared (Bug#9415).
16885 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16887 * search.c (boyer_moore): Take unibyte characters from pattern
16888 literally. (Bug#9458)
16890 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16892 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16894 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16896 Fix minor problem found by static checking.
16897 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16898 initialized, to pacify gcc -Wuninitialized.
16900 * fileio.c: Report proper errno when syscall falls.
16901 (Finsert_file_contents): Save and restore errno,
16902 so that report_file_error outputs the correct diagnostic.
16903 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16905 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16907 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16909 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16911 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16912 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16914 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16916 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16917 about the current paragraph and restore it after the call to reseat.
16919 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16920 (bidi_find_paragraph_start): Search back for paragraph beginning
16921 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16922 (bidi_move_to_visually_next): Only trigger paragraph-related
16923 computations when the last character is a newline or at EOB, not
16924 just any NEUTRAL_B. (Bug#9470)
16926 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16927 truncated lines if point is covered by a display string. (Bug#9524)
16929 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16931 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16932 (cons_to_x_long): New function.
16933 (lisp_data_to_selection_data): Use it. Correct the test for
16934 short-versus-long data; it was negated. Break out of vector
16935 loop, for efficiency, when a long datum is discovered.
16937 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16939 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16941 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16943 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16944 GCC PR/17406) by declaring this function with external scope.
16946 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16948 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16949 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16951 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16953 * editfns.c (Fformat): Correctly handle text properties on "%%".
16955 2011-09-15 Eli Zaretskii <eliz@gnu.org>
16957 * xterm.c (x_draw_composite_glyph_string_foreground):
16958 * w32term.c (x_draw_composite_glyph_string_foreground):
16959 * term.c (encode_terminal_code):
16960 * composite.c (composition_update_it, get_composition_id):
16961 * xdisp.c (get_next_display_element)
16962 (fill_composite_glyph_string): Add comments about special meaning
16963 of TAB characters in a composition.
16965 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16967 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16968 This occurs when processing a multibyte format.
16969 Problem reported by Wolfgang Jenker.
16971 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16973 * xdisp.c (try_cursor_movement): Only check for exact match if
16974 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16976 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16978 Remove unused external symbols.
16979 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16980 * xdisp.c (calc_pixel_width_or_height): Now static.
16981 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16982 * indent.c (check_display_width):
16983 * w32term.c: Fix comment to match code.
16984 * xterm.c, xterm.h (x_catching_errors): Remove.
16986 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16988 * xselect.c: Use signed conversions more consistently (Bug#9498).
16989 (selection_data_to_lisp_data): Assume incoming selection data are
16990 signed integers, not unsigned. This is to be consistent with
16991 outgoing selection data, which was modified to use signed integers
16992 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16993 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16994 expects long, not unsigned long.
16996 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16998 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16999 computation of loop end. Reported by Johan Bockgård
17002 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
17004 * frame.c (Fother_visible_frames_p): Function deleted.
17006 2011-09-12 Eli Zaretskii <eliz@gnu.org>
17008 * indent.c (compute_motion): Process display vector front to back
17009 rather than the other way around. (Bug#2496)
17011 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
17013 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
17015 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
17017 * minibuf.c (Fread_from_minibuffer): Doc fix.
17019 2011-09-11 Eli Zaretskii <eliz@gnu.org>
17021 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
17022 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
17024 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
17026 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
17027 value for non-existent files.
17029 2011-09-11 Eli Zaretskii <eliz@gnu.org>
17031 * fileio.c (Finsert_file_contents): If the file cannot be opened,
17032 set its "size" to -1. This will set the modtime_size field of
17033 the corresponding buffer to -1, which is what
17034 verify-visited-file-modtime expects for files that do not exist.
17037 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
17039 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
17041 * lisp.h: ... from here. push_key_description is no longer
17042 defined in keyboard.c, so its declaration should not be in
17043 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
17044 logically belongs with push_key_description.
17046 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
17048 * buffer.h: Include <sys/types.h> instead of <time.h>.
17049 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
17050 Problem reported by Herbert J. Skuhra.
17052 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
17054 * xml.c (parse_region): Make the parsing work for
17055 non-comment-starting XML files again (bug#9144).
17057 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
17059 * image.c (gif_load): Fix calculation of bottom and right corner.
17062 2011-09-10 Eli Zaretskii <eliz@gnu.org>
17064 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
17065 redisplay in small windows.
17067 2011-09-09 Eli Zaretskii <eliz@gnu.org>
17069 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
17071 2011-09-08 Martin Rudalics <rudalics@gmx.at>
17073 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
17074 Operate on live windows only.
17076 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
17078 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
17080 2011-09-07 Eli Zaretskii <eliz@gnu.org>
17082 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
17083 only under bidi iteration.
17085 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
17087 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
17089 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17091 isnan: Fix porting problem to Solaris 10 with bundled gcc.
17092 Without this fix, the command to link temacs failed due to an
17093 undefined symbol __builtin_isnan. This is because
17094 /usr/include/iso/math_c99.h #defines isnan(x) to
17095 __builtin_isnan(x), but the bundled gcc, which identifies itself
17096 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
17098 * floatfns.c (isnan): #undef, and then #define to a clone of
17100 (Fisnan): Always define, since it's always available now.
17101 (syms_of_floatfns): Always define isnan at the Lisp level.
17103 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17105 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
17107 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
17109 * fileio.c: Fix bugs with large file offsets (Bug#9428).
17110 The previous code assumed that file offsets (off_t values) fit in
17111 EMACS_INT variables, which is not true on typical 32-bit hosts.
17112 The code messed up by falsely reporting buffer overflow in cases
17113 such as (insert-file-contents "big" nil 1 2) into an empty buffer
17114 when "big" contains more than 2**29 bytes, even though this
17115 inserts just one byte and does not overflow the buffer.
17116 (Finsert_file_contents): Store file offsets as off_t
17117 values, not as EMACS_INT values. Check for overflow when
17118 converting between EMACS_INT and off_t. When checking for
17119 buffer overflow or for overlap, take the offsets into account.
17120 Don't use EMACS_INT for small values where int suffices.
17121 When checking for overlap, fix a typo: ZV was used where
17122 ZV_BYTE was intended.
17123 (Fwrite_region): Don't assume off_t fits into 'long'.
17124 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
17126 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
17128 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
17130 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17132 sprintf-related integer and memory overflow issues (Bug#9412).
17134 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
17135 (esprintf, exprintf, evxprintf): New functions.
17136 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
17137 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
17138 (modify_event_symbol): Do not assume that the length of
17139 name_alist_or_stem is safe to alloca and fits in int.
17140 (Fexecute_extended_command): Likewise for function name and binding.
17141 (Frecursion_depth): Wrap around reliably on integer overflow.
17142 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
17143 since some callers pass EMACS_INT values.
17144 (Fsingle_key_description): Don't crash if symbol name contains more
17145 than MAX_ALLOCA bytes.
17146 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
17147 (get_minibuffer): Arg is now EMACS_INT, not int.
17148 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
17149 (esprintf, exprintf, evxprintf): New decls.
17150 * window.h (command_loop_level, minibuf_level): Reflect API changes.
17152 * dbusbind.c (signature_cat): New function.
17153 (xd_signature, Fdbus_register_signal):
17154 Do not overrun buffer; instead, report string overflow.
17156 * dispnew.c (add_window_display_history): Don't overrun buffer.
17157 Truncate instead; this is OK since it's just a log.
17159 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
17160 even if the time zone offset is outlandishly large.
17161 Don't mishandle offset == INT_MIN.
17163 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
17164 when creating daemon; the previous buffer-overflow check was incorrect.
17166 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
17167 which has the guts of the old verror function.
17169 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
17170 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
17172 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
17173 (font_unparse_xlfd): Don't blindly alloca long strings.
17174 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
17175 fits in int, when using sprintf. Use single snprintf to count
17176 length of string rather than counting it via multiple sprintfs;
17177 that's simpler and more reliable.
17178 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
17179 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
17180 sprintf, in case result does not fit in int.
17182 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
17183 (fontset_from_font): Print it.
17185 * frame.c (tty_frame_count): Now printmax_t, not int.
17186 (make_terminal_frame, set_term_frame_name): Print it.
17187 (x_report_frame_params): In X, window IDs are unsigned long,
17188 not signed long, so print them as unsigned.
17189 (validate_x_resource_name): Check for implausibly long names,
17190 and don't assume name length fits in 'int'.
17191 (x_get_resource_string): Don't blindly alloca invocation name;
17192 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
17195 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
17196 (xg_check_special_colors, xg_set_geometry):
17197 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
17199 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
17200 Use esprintf, not sprintf, in case result does not fit in int.
17202 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17203 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
17204 it as a large positive number.
17205 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
17206 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
17208 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
17209 in case result does not fit in int.
17211 * print.c (float_to_string): Detect width overflow more reliably.
17212 (print_object): Make sprintf buffer a bit bigger, to avoid potential
17213 buffer overrun. Don't assume list length fits in 'int'. Treat
17214 print length of 0 as 0, not as infinity; to be consistent with other
17215 uses of print length in this function. Don't overflow print length
17216 index. Don't assume hash table size fits in 'long', or that
17217 vectorlike size fits in 'unsigned long'.
17219 * process.c (make_process): Use printmax_t, not int, to format
17220 process-name gensyms.
17222 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
17224 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
17225 to avoid potential buffer overrun.
17227 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
17228 if X resource line is longer than 512 bytes.
17230 * xfns.c (x_window): Make sprintf buffer a bit bigger
17231 to avoid potential buffer overrun.
17233 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
17235 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
17237 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
17239 Integer overflow fixes for scrolling, etc.
17240 Without these, Emacs silently mishandles large integers sometimes.
17241 For example, "C-u 4294967297 M-x recenter" was treated as if
17242 it were "C-u 1 M-x recenter" on a typical 64-bit host.
17244 * xdisp.c (try_window_id): Check Emacs fixnum range before
17245 converting to 'int'.
17247 * window.c (window_scroll_line_based, Frecenter):
17248 Check that an Emacs fixnum is in range before assigning it to 'int'.
17249 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
17250 values converted from Emacs fixnums.
17251 (Frecenter): Don't wrap around a line count if it is out of 'int'
17252 range; instead, treat it as an extreme value.
17253 (Fset_window_configuration, compare_window_configurations):
17254 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
17256 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
17257 that can exceed INT_MAX. Check that EMACS_INT value is in range
17258 before assigning it to the (possibly-narrower) index.
17259 (match_limit): Don't assume that a fixnum can fit in 'int'.
17261 * print.c (print_object): Use ptrdiff_t, not int, for index that can
17264 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
17265 (Fvertical_motion): Don't wrap around LINES values that don't fit
17266 in 'int'. Instead, treat them as extreme values. This is good
17267 enough for windows, which can't have more than INT_MAX lines anyway.
17269 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
17271 * Require libxml/parser.h to avoid compilation warning.
17273 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
17275 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
17276 since this reportedly can destroy thread storage.
17278 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
17280 * syntax.c (find_defun_start): Update all cache variables if
17281 exiting early (Bug#9401).
17283 2011-08-30 Eli Zaretskii <eliz@gnu.org>
17285 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
17287 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
17288 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
17289 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
17291 * term.c (tty_append_glyph): New function.
17292 (produce_stretch_glyph): Static function and its prototype deleted.
17294 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
17297 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
17299 * image.c (parse_image_spec): Check for nonnegative, not for positive,
17300 when checking :margin (Bug#9390).
17301 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
17302 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
17303 so that the name doesn't mislead. All uses changed.
17305 2011-08-28 Johan Bockgård <bojohan@gnu.org>
17307 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
17310 2011-08-27 Eli Zaretskii <eliz@gnu.org>
17312 * xdisp.c (move_it_to): Don't bail out early when reaching
17313 position beyond to_charpos, if we are scanning backwards.
17314 (move_it_vertically_backward): When DY == 0, make sure we get to
17315 the first character in the line after the newline.
17317 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
17319 * ccl.c: Improve and simplify overflow checking (Bug#9196).
17320 (ccl_driver): Do not generate an out-of-range pointer.
17321 (Fccl_execute_on_string): Remove unnecessary check for
17322 integer overflow, noted by Stefan Monnier in
17323 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
17324 Remove a FIXME that didn't need fixing.
17325 Simplify the newly-introduced buffer reallocation code.
17327 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
17329 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
17331 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
17333 Integer and memory overflow issues (Bug#9196).
17335 * doc.c (get_doc_string): Rework so that
17336 get_doc_string_buffer_size is the actual buffer size, rather than
17337 being 1 less than the actual buffer size; this makes xpalloc more
17340 * image.c (x_allocate_bitmap_record, cache_image):
17341 * xselect.c (Fx_register_dnd_atom):
17342 Simplify previous changes by using xpalloc.
17344 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,

17349 (charset_compare): Don't overflow if priorities differ greatly.
17350 (Fsort_charsets): Don't assume list length fits in int.
17351 Check for size-calculation overflow when allocating sort data.
17352 (syms_of_charset): Allocate an initial charset table that is
17353 just under 64 KiB, to avoid problems with glibc malloc and mmap.
17355 * cmds.c (internal_self_insert): Check for size-calculation overflow.
17357 * composite.h (struct composition.glyph_len): Now int, not unsigned.
17358 The actual value is always <= INT_MAX, and leaving it unsigned made

17361 * dispextern.h (struct glyph_matrix.rows_allocated)
17362 (struct face_cache.size): Now ptrdiff_t, for convenience in use
17363 with xpalloc. The values are still always <= INT_MAX.

17373 (revalidate_region_cache, know_region_cache, region_cache_forward)
17374 (region_cache_backward, pp_cache):
17375 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
17376 so that ptrdiff_t * can be passed to xpalloc.
17377 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
17378 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

17393 * buffer.c (overlays_at, overlays_in, record_overlay_string)
17395 Don't update size of array until after memory allocation succeeds,
17396 because xmalloc/xrealloc may not return.
17397 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
17398 now that we have proper integer overflow checking.
17399 (record_overlay_string, overlay_strings): Catch overflows when
17400 calculating size of overlay_str_buf.
17402 * callproc.c (Fcall_process): Check for size overflow when
17403 calculating size of args2.
17404 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
17405 Normally we prefer signed values, but sticking with ptrdiff_t would
17406 require adding more-complicated checks.
17408 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
17409 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
17410 Redo buffer-overflow calculations to avoid integer overflow.
17411 Add a FIXME comment where memory seems to be over-allocated.
17413 * character.c (Fstring): Check for size-calculation overflow.
17415 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid

17449 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
17451 * emacs.c (main): Do not reallocate argv, since there is a null at
17452 the end that can be overwritten, and this way there's no need to
17453 worry about size-calculation overflow.
17454 (sort_args): Check for size-calculation overflow.
17456 * eval.c (init_eval_once, grow_specpdl): Don't update size until

17462 Check for integer overflow.
17463 (x_set_alpha): Do not assume XINT fits in int.
17465 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
17466 This is for the members text_lines, text_cols, total_lines, total_cols,
17467 where the system imposes an 'int' limit.
17469 * fringe.c (Fdefine_fringe_bitmap):
17470 Don't update size until alloc works.

17475 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
17476 Check for size-calculation overflow.
17477 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
17478 do, as we prefer signed integers.

17485 * gtkutil.h: Change prototypes to match the above.
17487 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

17534 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
17535 for command line length. Do not attempt to address one before the
17536 beginning of an array, as that's not portable.

17577 Don't update size until alloc done.
17579 * xrdb.c (get_environ_db): Don't assume path length fits in int,

17582 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
17583 (X_LONG_MIN): New macros.
17584 Use them to make the following changes clearer.
17585 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
17586 This change doesn't affect the value now, but it may help remind
17587 future maintainers not to raise the value too much later.
17588 (SELECTION_QUANTUM): Remove, replacing with ...
17589 (selection_quantum): ... new function, which avoids overflow.
17591 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
17592 assumption that selection length fits in 'int'.

17609 Don't store size until memory allocation succeeds.
17610 (x_get_window_property): Plug memory leak on memory exhaustion.
17611 Don't double-block input; malloc is safe here. Don't assume 2**34
17612 - 4 fits in unsigned long. Add an xassert to check
17613 XGetWindowProperty overflow. Be more careful about overflow
17614 calculations, and distinguish size from memory overflow better.
17615 (receive_incremental_selection): When tracing, don't assume
17616 unsigned int is less than INT_MAX.
17617 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
17618 harmful) conversions of unsigned short to int.
17619 (lisp_data_to_selection_data): Don't assume that integers
17620 in the range -65535 through -1 fit in an X unsigned short.
17621 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17622 result parameters unless successful. Rely on cons_to_unsigned
17623 to report problems with elements; the old code wasn't right anyway.
17624 (x_check_property_data): Check for int overflow; we cannot use
17625 a wider type due to X limits.

17658 * lisp.h (hash_lookup, hash_put):
17659 * minibuf.c (Ftest_completion):
17660 Use ptrdiff_t for hash table indexes, not int (which is too
17661 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17662 32-bit --with-wide-int hosts).
17664 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17665 Add a FIXME comment about memory leaks.

17673 with outlandish widths.
17674 * character.h (sanitize_tab_width): Rename from sanitize_width,
17675 now that we have two such functions. All uses changed.

17696 exceed limits imposed by XClientMessageEvent, as well as the usual
17697 ptrdiff_t and size_t limits.
17699 * keyboard.c: Overflow, signedness and related fixes.
17700 (make_lispy_movement): Use same integer type in forward decl
17701 that is used in the definition.
17702 (read_key_sequence, keyremap_step):
17703 Change bufsize argument back to int, undoing my 2011-03-30 change.
17704 We prefer signed types, and int is wide enough here.
17705 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17706 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17707 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17708 length, not size_t. Use ptrdiff_t for index, not int.
17709 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17710 possibility of integer overflow.

17734 (lookup_image): Remove unnecessary tests.
17735 (xbm_image_p): Locals are now of int, not EMACS_INT,
17736 since parse_image_check makes sure they fit into int.
17737 (png_load, gif_load, svg_load_image):
17738 Prefer int to unsigned where either will do.
17739 (tiff_handler): New function, combining the cores of the
17740 old tiff_error_handler and tiff_warning_handler.
17741 This function is rewritten to use vsnprintf and thereby avoid
17742 stack buffer overflows. It uses only the features of vsnprintf
17743 that are common to both POSIX and native Microsoft.
17744 (tiff_error_handler, tiff_warning_handler): Use it.
17745 (tiff_load, gif_load, imagemagick_load_image):
17746 Don't assume :index value fits in 'int'.
17747 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17748 (imagemagick_load_image): Check that crop parameters fit into
17749 the integer types that MagickCropImage accepts. Don't assume
17750 Vimagemagick_render_type has a nonnegative value. Don't assume
17751 size_t fits in 'long'.
17752 (gs_load): Use printmax_t to print the widest integers possible.

17766 (handle_single_display_spec): If the display spec is of the form
17767 `(space ...)', and specifies display in the text area, return 2
17769 (try_cursor_movement): Check for the need to scroll more
17770 accurately, and prefer exact match for point under bidi.
17771 Don't advance `row' beyond the last row of the window.

17789 buffers, return left-to-right.
17790 (set_cursor_from_row): Consider candidate row a win if its glyph
17791 represents a newline and point is on that newline. Fixes cursor
17792 positioning on the newline at EOL of R2L text within L2R
17793 paragraph, and vice versa.
17794 (try_cursor_movement): Check continued rows, in addition to
17795 continuation rows. Fixes unwarranted scroll when point enters a

17824 * xdisp.c (redisplay_window): When computing centering_position,
17825 account for the height of the header line. (Bug#8874)
17827 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17828 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17829 candidate is selected by the mouse, and that candidate has a
17830 composed character under the mouse.
17832 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17833 coordinates reported by pos-visible-in-window-p for a composed
17834 character in column zero.
17836 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

17843 consider it a hit if to_charpos is anywhere in the range of the
17844 composed buffer positions.
17846 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17848 * image.c (gif_load): Don't assume that each subimage has the same
17849 dimensions as the base image. Handle disposal method that is
17850 "undefined" by the gif spec (Bug#9335).
17852 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17854 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17859 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
17860 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17861 from an Org mode buffer to a Speedbar frame.
17863 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17864 a composition, take its buffer position from IT->cmp_it.charpos.
17865 Fixes cursor positioning at the beginning of a line that begins
17866 with a composed character.
17868 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17870 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17871 character bidirectional type, use STRONG_L instead. Fixes crashes
17872 in a buffer produced by `describe-categories'.
17874 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17875 members before the level stack, so they would be saved and
17876 restored when copying iterator state. Fixes incorrect reordering
17877 around TABs covered by display properties.
17879 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17881 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

17965 the event loop. Get status from as_status (Bug#7276).
17967 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17968 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17969 the event loop (Bug#7276).
17971 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

17995 (Fnetwork_interface_list): Allocate in increments of bytes instead
17996 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17997 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17999 (struct ifflag_def): notrailers is smart on OSX.
18000 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
18001 Get hardware address with getifaddrs if available.

18005 * xdisp.c (iterate_out_of_display_property): xassert that
18006 IT->position is set to within IT->object's boundaries. Break from

18009 Set IT->current to match the bidi iterator unconditionally.
18010 (push_display_prop): Allow GET_FROM_STRING as IT->method on
18011 entry. Force push_it to save on the stack the current
18012 buffer/string position, to be restored by pop_it. Fix flags in
18013 the iterator structure wrt the object coming from a display
18014 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
18015 properties. (Bug#9284)
18017 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
18019 * fontset.c (fontset_get_font_group): Add proper type checks.

18058 longlines-mode. (Bug#9254)
18059 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
18060 word-wrap under bidirectional display. (Bug#9224)
18062 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
18063 is non-zero, even if the data buffer is NULL. Fixes a crash in
18064 vertical-motion with longlines-mode. (Bug#9254)
18066 2011-08-05 Eli Zaretskii <eliz@gnu.org>
18068 * bidi.c <bidi_cache_total_alloc>: Now static.

18074 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
18075 amount allocated this far in `bidi_cache_total_alloc'.
18076 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
18077 non-zero, only free the data buffer without restoring the cache
18078 contents. All callers changed.
18080 * dispextern.h (bidi_unshelve_cache): Update prototype.
18082 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

18084 (move_it_vertically_backward, move_it_by_lines): Replace the call
18085 to xfree to an equivalent call to bidi_unshelve_cache.
18086 (move_it_in_display_line_to): Fix logic of returning

18143 DISP_PROP_P, and pass it to compute_display_string_pos.
18144 Only handle text covered by a display string if DISP_PROP_P is returned
18145 non-zero. All callers of bidi_fetch_char changed.

18236 In other words, assume that every image size is allowed, on non-X

18239 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
18241 * regex.c (re_iswctype): Convert return values to boolean.
18243 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
18245 * xdisp.c (compute_display_string_pos): Don't use cached display
18246 string position if the buffer had its restriction changed.
18249 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18251 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18253 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
18255 Integer signedness and overflow and related fixes. (Bug#9079)
18257 * bidi.c: Integer size and overflow fixes.
18258 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
18259 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
18260 (bidi_cache_find_level_change, bidi_cache_ensure_space)
18261 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
18262 (bidi_find_other_level_edge):
18263 Use ptrdiff_t instead of EMACS_INT where either will do.
18264 This works better on 32-bit hosts configured --with-wide-int.
18265 (bidi_cache_ensure_space): Check for size-calculation overflow.
18266 Use % rather than repeated addition, for better worst-case speed.
18267 Don't set bidi_cache_size until after xrealloc returns, because it
18269 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
18270 (bidi_cache_ensure_space): Also check that the bidi cache size
18271 does not exceed that of the largest Lisp string or buffer. See Eli
18272 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
18274 * alloc.c (__malloc_size_t): Remove.
18275 All uses replaced by size_t. See Andreas Schwab's note
18276 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
18278 * image.c: Improve checking for integer overflow.
18279 (check_image_size): Assume that f is nonnull, since
18280 it is always nonnull in practice. This is one less thing to
18281 worry about when checking for integer overflow later.
18282 (x_check_image_size): New function, which checks for integer
18283 overflow issues inside X.
18284 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
18285 This removes the need for a memory_full check.
18286 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
18287 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
18288 (xbm_read_bitmap_data): Change locals back to 'int', since
18289 their values must fit in 'int'.
18290 (xpm_load_image, png_load, tiff_load):
18291 Invoke x_create_x_image_and_pixmap earlier,
18292 to avoid much needless work if the image is too large.
18293 (tiff_load): Treat overly large images as if
18294 x_create_x_image_and_pixmap failed, not as malloc failures.
18295 (gs_load): Use x_check_image_size.
18297 * gtkutil.c: Omit integer casts.
18298 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
18299 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
18301 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
18303 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
18304 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
18305 would wrongly return t on a 64-bit host.
18307 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
18308 The plain *_OVERFLOW macros run afoul of GCC bug 49705
18309 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
18310 and therefore cause GCC to emit a bogus diagnostic in some cases.
18312 * image.c: Integer signedness and overflow and related fixes.
18313 This is not an exhaustive set of fixes, but it's time to
18314 record what I've got.
18315 (lookup_pixel_color, check_image_size): Remove redundant decls.
18316 (check_image_size): Don't assume that arbitrary EMACS_INT values
18317 fit in 'int', or that arbitrary 'double' values fit in 'int'.
18318 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
18319 (tiff_load, imagemagick_load_image):
18320 Check for overflow in size calculations.
18321 (x_create_x_image_and_pixmap): Remove unnecessary test for
18322 xmalloc returning NULL; that can't happen.
18323 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
18324 (xpm_color_bucket): Use better integer hashing function.
18325 (xpm_cache_color): Don't possibly over-allocate memory.
18326 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
18327 (gif_memory_source):
18328 Use ptrdiff_t, not int or size_t, to record sizes.
18329 (png_load): Don't assume values greater than 2**31 fit in 'int'.
18330 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
18331 either works, as we prefer signed integers.
18332 (tiff_read_from_memory, tiff_write_from_memory):
18333 Return tsize_t, not size_t, since that's what the TIFF API wants.
18334 (tiff_read_from_memory): Don't fail simply because the read would
18335 go past EOF; instead, return a short read.
18336 (tiff_load): Omit no-longer-needed casts.
18337 (Fimagemagick_types): Don't assume size fits into 'int'.
18339 Improve hashing quality when configured --with-wide-int.
18340 * fns.c (hash_string): New function, taken from sxhash_string.
18341 Do not discard information about ASCII character case; this
18342 discarding is no longer needed.
18343 (sxhash-string): Use it. Change sig to match it. Caller changed.
18344 * lisp.h: Declare it.
18345 * lread.c (hash_string): Remove, since we now use fns.c's version.
18346 The fns.c version returns a wider integer if --with-wide-int is
18347 specified, so this should help the quality of the hashing a bit.
18349 * emacs.c: Integer overflow minor fix.
18350 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
18351 Define only if GNU_LINUX.
18352 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
18354 * dispnew.c: Integer signedness and overflow fixes.
18355 Remove unnecessary forward decls, that were a maintenance hassle.
18356 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
18358 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
18359 (scrolling_window): Use ptrdiff_t, not int, for byte count.
18360 (prepare_desired_row, line_draw_cost):
18361 Use int, not unsigned, where either works.
18362 (save_current_matrix, restore_current_matrix):
18363 Use ptrdiff_t, not size_t, where either works.
18364 (init_display): Check for overflow more accurately, and without
18365 relying on undefined behavior.
18367 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
18368 Remove, replacing with the new symbols in lisp.h. All uses changed.
18369 * fileio.c (make_temp_name):
18370 * filelock.c (lock_file_1, lock_file):
18371 * xdisp.c (message_dolog):
18372 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
18373 Use pMd etc. instead.
18374 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
18375 replacing the pWIDE etc. symbols removed from editfns.c.
18377 * keyboard.h (num_input_events): Now uintmax_t.
18378 This is (very slightly) less likely to mess up due to wraparound.
18381 * buffer.c: Integer signedness fixes.
18382 (alloc_buffer_text, enlarge_buffer_text):
18383 Use ptrdiff_t rather than size_t when either will do, as we prefer
18386 * alloc.c: Integer signedness and overflow fixes.
18387 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
18388 (__malloc_size_t): Default to size_t, not to int.
18389 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
18390 (Fgarbage_collect, mark_object_loop_halt, mark_object):
18391 Prefer ptrdiff_t to size_t when either would do, as we prefer
18393 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
18394 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
18395 Now const. Initialize with values that are in range even if char
18397 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
18398 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
18399 These functions do the right thing with sizes > 2**32.
18400 (check_depth): Now ptrdiff_t, not int.
18401 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
18402 Adjust to new way of storing sizes. Check for size overflow bugs
18404 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
18405 slightly wrong anyway, as it missed one instance of
18406 XMALLOC_OVERRUN_CHECK_OVERHEAD.
18407 (refill_memory_reserve): Omit needless cast to size_t.
18408 (mark_object_loop_halt): Mark as externally visible.
18410 * xselect.c: Integer signedness and overflow fixes.
18411 (Fx_register_dnd_atom, x_handle_dnd_message):
18412 Use ptrdiff_t, not size_t, since we prefer signed.
18413 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
18414 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
18415 x_dnd_atoms_size and x_dnd_atoms_length.
18417 * doprnt.c: Prefer signed to unsigned when either works.
18419 * doprnt.c (doprnt):
18421 * xdisp.c (vmessage):
18422 Use ptrdiff_t, not size_t, when using or implementing doprnt,
18423 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
18424 prefer signed arithmetic to avoid comparison confusion.
18425 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
18426 but is a bit tricky.
18428 Assume freestanding C89 headers, string.h, stdlib.h.
18429 * data.c, doprnt.c, floatfns.c, print.c:
18430 Include float.h unconditionally.
18431 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
18432 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
18433 * regex.c: Likewise for stddef.h, string.h.
18434 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
18435 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
18436 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
18437 (STDC_HEADERS): Remove obsolete defines.
18438 * sysdep.c: Include limits.h unconditionally.
18440 Assume support for memcmp, memcpy, memmove, memset.
18441 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
18442 * regex.c (memcmp, memcpy):
18443 Remove; we assume C89 now.
18445 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
18446 (__malloc_safe_bcopy): Remove; no longer needed.
18448 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
18449 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
18450 well either way, and we prefer signed to unsigned.
18452 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
18454 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
18455 closes the connection while we're reading (bug#9182).
18457 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
18459 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
18460 are specified (Bug#9168).
18462 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
18464 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
18465 Found by GCC static checking and --with-wide-int on a 32-bit host.
18467 2011-07-25 Eli Zaretskii <eliz@gnu.org>
18469 * xdisp.c (compute_display_string_pos): Fix logic of caching
18470 previous display string position. Initialize cached_prev_pos to
18471 -1. Fixes slow-down at the beginning of a buffer.
18473 2011-07-24 Eli Zaretskii <eliz@gnu.org>
18475 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
18476 for attrs[LFACE_FONTSET_INDEX].
18478 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
18480 * xml.c (parse_region): Remove unused local
18481 that was recently introduced.
18483 2011-07-23 Eli Zaretskii <eliz@gnu.org>
18485 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
18486 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
18488 * xdisp.c (move_it_in_display_line_to): Record the best matching
18489 position for TO_CHARPOS while scanning the line, and restore it on
18490 exit if none of the characters scanned was an exact match.
18491 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
18492 when exact match is impossible due to invisible text, and the
18493 lines are truncated.
18495 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
18497 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
18500 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18502 Fix a significant slow-down of cursor motion with C-n, C-p,
18503 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
18504 auto-repeat under bidi redisplay in fontified buffers.
18505 * xdisp.c (compute_stop_pos_backwards): New function.
18506 (next_element_from_buffer): Call compute_stop_pos_backwards to
18507 find a suitable prev_stop when we find ourselves before
18509 (reseat): Don't look for prev_stop, as that could mean a very long
18511 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
18512 <cached_disp_overlay_modiff>: Cache for last found display string
18514 (compute_display_string_pos): Return the cached position if asked
18515 about the same buffer in the same area of character positions, and
18516 the buffer wasn't changed since the time the display string
18517 position was cached.
18519 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18521 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
18522 is an integer, which is important for empty lines. (Bug#9149)
18524 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
18526 * frame.c (Fmodify_frame_parameters): In tty case, update the
18527 default face if necessary (Bug#4238).
18529 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
18531 * editfns.c (Fstring_to_char): No need to explain what a character
18532 is in the docstring (Bug#6576).
18534 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18536 * xml.c (parse_region): Make sure we always return a tree.
18538 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
18540 * xml.c (parse_region): If a document contains only comments,
18543 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18545 * xml.c (make_dom): Return comments, too.
18547 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
18550 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
18551 and the surrounding thread.
18552 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
18553 rather than fgets, and retry after EINTR. Otherwise, 'emacs
18554 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
18556 * s/openbsd.h (BROKEN_SIGIO): Define.
18557 * unexelf.c (unexec) [__OpenBSD__]:
18558 Don't update the .mdebug section of the Alpha COFF symbol table.
18560 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
18562 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
18565 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
18567 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
18568 This fixes some race conditions on the permissions of any newly
18571 * alloc.c (valid_pointer_p): Use pipe, not open.
18572 This fixes some permissions issues when debugging.
18574 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
18575 If fchown fails to set both uid and gid, try to set just gid,
18576 as that is sometimes allowed. Adjust the file's mode to eliminate
18577 setuid or setgid bits that are inappropriate if fchown fails.
18579 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
18581 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
18582 to compare Lisp_Objects.
18583 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
18584 global_gnutls_log_level, don't mistake it for a Lisp_Object.
18585 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
18587 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
18589 * lread.c (read_integer): Unread even EOF character.
18590 (read1): Likewise. Properly record start position of symbol.
18592 * lread.c (read1): Read `#:' as empty uninterned symbol if no
18593 symbol character follows.
18595 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
18597 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
18598 This works around a problem with the previous change to Fcopy_file.
18599 Recent glibc declares fchown with __attribute__((warn_unused_result)),
18600 and without this change, GCC might complain about discarding
18601 fchown's return value.
18603 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
18605 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
18607 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
18609 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
18611 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
18613 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
18614 it's used from the C level.
18616 * process.c: Use the same condition for POLL_FOR_INPUT in both
18617 keyboard.c and process.c (bug#1858).
18619 2011-07-09 Lawrence Mitchell <wence@gmx.li>
18621 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
18622 (Fgnutls_boot): Use it.
18624 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
18626 * doc.c (Fsubstitute_command_keys): Revert last change.
18628 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18630 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18631 quotes the next character, and doesn't affect other longer
18632 sequences (bug#8935).
18634 * lread.c (syms_of_lread): Clarify that is isn't only
18635 `eval-buffer' and `eval-defun' that's affected by
18636 `lexical-binding' (bug#8460).
18638 2011-07-15 Eli Zaretskii <eliz@gnu.org>
18640 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18641 bidi redisplay when a line includes both an image and is truncated.
18643 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18645 Fix minor problems found by static checking.
18646 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18647 (elsz): Now a signed constant, not a size_t var. We prefer signed
18648 types to unsigned, to avoid integer comparison confusion. Without
18649 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18650 "cannot optimize loop, the loop counter may overflow", a symptom
18652 * indent.c (Fvertical_motion): Mark locals as initialized.
18653 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18655 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
18657 * search.c (Fre_search_backward): Mention `case-fold-search' in
18658 all the re_search_* functions (bug#8138).
18660 * keyboard.c (Fopen_dribble_file): Document when the file is
18663 2011-07-14 Eli Zaretskii <eliz@gnu.org>
18665 * bidi.c (bidi_dump_cached_states): Fix format of displaying
18668 Support bidi reordering of display and overlay strings.
18669 * xdisp.c (compute_display_string_pos)
18670 (compute_display_string_end): Accept additional argument STRING.
18671 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
18672 (reseat_to_string): Initialize bidi_it->string.s and
18673 bidi_it->string.schars.
18674 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
18675 NULL (avoids a crash in bidi_paragraph_init).
18676 Initialize itb.string.lstring.
18677 (init_iterator): Call bidi_init_it only of a valid
18678 buffer position was specified. Initialize paragraph_embedding to
18680 (reseat_to_string): Initialize the bidi iterator.
18681 (display_string): If we need to ignore text properties of

19177 (clone_per_buffer_values): Don't assume that

19179 This isn't true in general, and it's particularly not true
19180 if Emacs is configured with --with-wide-int.
19181 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
19182 New macros, used in the buffer.c change.

19218 Random fixes. E.g., (random) never returned negative values.
19219 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
19220 subseconds part to the entropy, as that's a bit more random.
19221 Prefer signed to unsigned, since the signedness doesn't matter and
19222 in general we prefer signed. When given a limit, use a
19223 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
19224 latter isn't right if USE_2_TAGS_FOR_INTS.
19225 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
19226 not 0..VALMASK. Don't discard "excess" bits that random () returns.

19230 * textprop.c (text_property_stickiness):
19231 Obey Vtext_property_default_nonsticky.

19238 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
19239 This is more efficient than Ffile_directory_p and avoids a minor race.
19241 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
19243 * buffer.c (Foverlay_put): Say what the return value is
19246 * fileio.c (barf_or_query_if_file_exists): Check first if the file
19247 is a directory before asking whether to use the file name
19249 (barf_or_query_if_file_exists): Make the "File is a directory"
19250 error be more correct.
19252 * fns.c (Frequire): Remove the mention of the .gz files, since
19253 that's installation-specific, but keep the mention of
19254 `get-load-suffixes'.

19266 Qgnutls_bootprop_verify_error (which is no longer used).
19268 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
19269 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
19270 Also (re)move comments that are misplaced or no longer relevant.
19272 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
19274 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

19333 (syms_of_keymap): Defsubr make-composed-keymap.
19334 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

19371 * eval.c (struct backtrace): Simplify and port the data structure.
19372 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
19373 signed bit field, as this assumption is not portable and it makes
19374 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
19375 "char debug_on_exit : 1" as this is not portable either; instead,
19376 use the portable "unsigned int debug_on_exit : 1". Remove unused
19377 member evalargs. Remove obsolete comments about cc bombing out.
19379 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

19558 Check for size-calculation overflow.
19559 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
19561 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
19563 * lread.c: Integer overflow fixes.
19564 (read_integer): Radix is now EMACS_INT, not int,
19565 to improve quality of diagnostics for out-of-range radices.
19566 Calculate buffer size correctly for out-of-range radices.
19567 (read1): Check for integer overflow in radices, and in
19568 read-circle numbers.
19569 (read_escape): Avoid int overflow.
19570 (Fload, openp, read_buffer_size, read1)
19571 (substitute_object_recurse, read_vector, read_list, map_obarray):
19572 Use ptrdiff_t, not int, for sizes.

19574 Check for size overflow.
19576 * image.c (cache_image): Check for size arithmetic overflow.
19578 * lread.c: Integer overflow issues.
19579 (saved_doc_string_size, saved_doc_string_length)

19587 2011-06-22 Leo Liu <sdl.web@gmail.com>
19589 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
19590 Move to minibuffer.el.
19592 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19594 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
19595 The following patches are for when GLYPH_DEBUG && !XASSERT.
19596 * dispextern.h (trace_redisplay_p, dump_glyph_string):
19597 * dispnew.c (flush_stdout):
19598 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
19599 Mark as externally visible.
19600 * dispnew.c (check_window_matrix_pointers): Now static.
19601 * dispnew.c (window_to_frame_vpos):
19602 * xfns.c (unwind_create_frame):
19603 * xterm.c (x_check_font): Remove unused local.
19604 * scroll.c (CHECK_BOUNDS):
19605 * xfaces.c (cache_fache): Rename local to avoid shadowing.
19606 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
19607 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
19608 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
19609 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
19611 (debug_method_add): Use va_list and vsprintf rather than relying
19612 on undefined behavior with wrong number of arguments.
19613 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19614 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19615 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19616 since we're not interested in debugging glyphs with old libraries.
19617 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19618 GCC 4.6.0's static checking.
19620 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19622 Integer overflow and signedness fixes (Bug#8873).

19631 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
19632 (x_create_bitmap_from_xpm_data):
19633 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
19634 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
19636 * xfaces.c (load_pixmap):
19637 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
19638 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
19639 (.bitmaps_last, struct x_output.icon_bitmap):
19640 Use ptrdiff_t, not int, for bitmap indexes.
19641 (x_allocate_bitmap_record): Check for size overflow.
19642 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
19644 Use ptrdiff_t, not int, for overlay counts.
19645 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
19646 * editfns.c (overlays_around, get_pos_property):
19647 * textprop.c (get_char_property_and_overlay):
19648 * xdisp.c (next_overlay_change, note_mouse_highlight):
19649 * xfaces.c (face_at_buffer_position):
19650 * buffer.c (OVERLAY_COUNT_MAX): New macro.
19651 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
19652 (Fnext_overlay_change, Fprevious_overlay_change)
19653 (mouse_face_overlay_overlaps, Foverlays_in):
19654 Use ptrdiff_t, not int, for sizes.
19655 (overlays_at, overlays_in): Check for size-calculation overflow.
19657 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19659 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19660 (x_session_initialize): Do not assume string length fits in int.
19662 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19663 This is unlikely, but can occur if DPI is outlandish.
19665 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19666 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19668 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
19669 * xrdb.c (magic_file_p, search_magic_path):
19670 Omit last arg SUFFIX; it was always 0. All callers changed.
19671 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
19673 * xfont.c (xfont_match): Avoid need for strlen.
19675 * xfns.c: Don't assume strlen fits in int.
19676 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
19678 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19679 not unsigned long, as we prefer signed integers. All callers changed.
19680 Detect integer overflow in repeat count.
19681 (message_dolog): Don't assume print length fits in 39 bytes.
19682 (display_mode_element): Don't assume strlen fits in int.
19684 * termcap.c: Don't assume sizes fit in int and never overflow.
19685 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
19686 (gobble_line): Check for size-calculation overflow.
19688 * minibuf.c (Fread_buffer):
19689 * lread.c (intern, intern_c_string):
19690 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
19691 Don't assume string length fits in int.
19693 * keyboard.c (parse_tool_bar_item):
19694 * gtkutil.c (style_changed_cb): Avoid need for strlen.
19696 * font.c: Don't assume string length fits in int.
19697 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
19698 Use ptrdiff_t, not int.
19699 (font_intern_prop): Don't assume string length fits in int.
19700 Don't assume integer property fits in fixnum.
19701 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19703 * filelock.c: Fix some buffer overrun and integer overflow issues.
19704 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19705 Reformulate so as not to need the command string.
19706 Invoke gzip -cd rather than gunzip, as it's more portable.
19707 (lock_info_type, lock_file_1, lock_file):
19708 Don't assume pid_t and time_t fit in unsigned long.
19709 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19710 (current_lock_owner): Prefer signed type for sizes.
19711 Use memcpy, not strncpy, where memcpy is what is really wanted.
19712 Don't assume (via atoi) that time_t and pid_t fit in int.
19713 Check for time_t and/or pid_t out of range, e.g., via a network share.
19714 Don't alloca where an auto var works fine.
19716 * fileio.c: Fix some integer overflow issues.
19717 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19718 Don't assume string length fits in int.
19719 (directory_file_name): Don't assume string length fits in long.
19720 (make_temp_name): Don't assume pid fits in int, or that its print
19721 length is less than 20.
19723 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19725 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19727 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19729 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19730 We prefer signed integers, even for size calculations.
19732 * emacs.c: Don't assume string length fits in 'int'.
19733 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19734 (main): Don't invoke strlen when not needed.
19736 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
19737 (XD_DEBUG_MESSAGE): Don't waste a byte.
19739 * callproc.c (getenv_internal_1, getenv_internal)
19740 (Fgetenv_internal):
19741 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19743 * lread.c (invalid_syntax): Omit length argument.
19744 All uses changed. This doesn't fix a bug, but it simplifies the
19745 code away from its former Hollerith-constant appearance, and it's
19746 one less 'int' to worry about when looking at integer-overflow issues.
19747 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19749 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19750 This didn't break anything, but it didn't help either.
19751 It's confusing to put a bogus integer in a place where the actual
19752 value does not matter.
19753 (LIST_END_P): Remove unused macro and its bogus comment.
19754 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19756 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19757 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19759 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19760 We prefer signed types, and the value cannot exceed the EMACS_INT
19761 range anyway (because otherwise the length would not be representable).
19762 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19763 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19764 This avoids a GCC warning when WIDE_EMACS_INT.
19766 * indent.c (sane_tab_width): New function.
19767 (current_column, scan_for_column, Findent_to, position_indentation)
19768 (compute_motion): Use it. This is just for clarity.
19769 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19771 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19773 * lisp.h (lint_assume): New macro.
19774 * composite.c (composition_gstring_put_cache):
19775 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19777 * editfns.c, insdel.c:
19778 Omit unnecessary forward decls, to simplify future changes.
19780 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19782 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19784 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19785 Use much-faster test for byte-length change.
19786 Don't assume string byte-length fits in 'int'.
19787 Check that character arg fits in 'int'.
19788 (mapcar1): Declare byte as byte, for clarity.
19790 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19792 * fns.c (concat): Catch string overflow earlier.
19793 Do not rely on integer wraparound.
19795 * dispextern.h (struct it.overlay_strings_charpos)
19796 (struct it.selective): Now EMACS_INT, not int.
19797 * xdisp.c (forward_to_next_line_start)
19798 (back_to_previous_visible_line_start)
19799 (reseat_at_next_visible_line_start, next_element_from_buffer):
19800 Don't arbitrarily truncate the value of 'selective' to int.
19802 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19804 * composite.c: Don't truncate sizes to 'int'.
19805 (composition_gstring_p, composition_reseat_it)
19806 (composition_adjust_point): Use EMACS_INT, not int.
19807 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19808 not EMACS_UINT, for indexes.
19810 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19812 * buffer.c: Include <verify.h>.
19813 (struct sortvec.priority, struct sortstr.priority):
19814 Now EMACS_INT, not int.
19815 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19816 (struct sortstr.size, record_overlay_string)
19817 (struct sortstrlist.size, struct sortlist.used):
19818 Don't truncate size to int.
19819 (record_overlay_string): Check for size-calculation overflow.
19820 (init_buffer_once): Check at compile-time, not run-time.
19822 2011-06-22 Jim Meyering <meyering@redhat.com>
19824 Don't leak an XBM-image-sized buffer
19825 * image.c (xbm_load): Free the image buffer after using it.
19827 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19830 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19831 that Sun C diagnosed.
19832 * fns.c (secure_hash): Fix pointer signedness issue.
19833 * intervals.c (static_offset_intervals): New function.
19834 (offset_intervals): Use it.
19836 2011-06-21 Leo Liu <sdl.web@gmail.com>
19839 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19842 * fns.c (secure_hash): Rename from crypto_hash_function and change
19843 the first arg to accept symbols.
19844 (Fsecure_hash): New primitive.
19845 (syms_of_fns): New symbols.
19847 2011-06-20 Deniz Dogan <deniz@dogan.se>
19849 * process.c (Fset_process_buffer): Clarify return value in
19852 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19854 * dispnew.c (add_window_display_history): Use BVAR.
19856 * xdisp.c (debug_method_add): Use BVAR.
19857 (check_window_end, dump_glyph_matrix, dump_glyph)
19858 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19860 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19863 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19864 check till after the cache is created in init_frame_faces.
19866 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19868 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19870 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19872 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19873 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19874 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19876 Improve buffer-overflow checking (Bug#8873).
19877 * fileio.c (Finsert_file_contents):
19878 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19879 Remove the old (too-loose) buffer overflow checks.
19880 They weren't needed, since make_gap checks for buffer overflow.
19881 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19882 The old code merely checked for Emacs fixnum overflow, and relied
19883 on undefined (wraparound) behavior. The new code avoids undefined
19884 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19886 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19887 Tune. Don't use wider integers than needed. Don't use alloca.
19888 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19890 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19892 * insdel.c, lisp.h (buffer_overflow): New function.
19893 (insert_from_buffer_1, replace_range, replace_range_2):
19894 * insdel.c (make_gap_larger):
19895 * editfns.c (Finsert_char):
19896 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19898 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19900 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19902 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19904 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19905 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19907 * fileio.c: Don't assume EMACS_INT fits in off_t.
19908 (emacs_lseek): New static function.
19909 (Finsert_file_contents, Fwrite_region): Use it.
19910 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19912 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19914 * fns.c: Don't overflow int when computing a list length.
19915 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19916 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19917 truncation on 64-bit hosts. Check for QUIT every
19918 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19919 faster and is responsive enough.
19920 (Flength): Report an error instead of overflowing an integer.
19921 (Fsafe_length): Return a float if the value is not representable
19922 as a fixnum. This shouldn't happen except in contrived situations.
19923 (Fnthcdr, Fsort): Don't assume list length fits in int.
19924 (Fcopy_sequence): Don't assume vector length fits in int.
19926 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19927 (header_size, word_size): New constants.
19928 (allocate_vectorlike): Don't check size overflow here.
19929 (allocate_vector): Check it here instead, since this is the only
19930 caller of allocate_vectorlike that could cause overflow.
19931 Check that the new vector's length is representable as a fixnum.
19933 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19934 The previous code was bogus. For example, next_almost_prime (32)
19935 returned 39, which is undesirable as it is a multiple of 3; and
19936 next_almost_prime (24) returned 25, which is a multiple of 5 so
19937 why was the code bothering to check for multiples of 7?
19939 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19941 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19943 Variadic C functions now count arguments with ptrdiff_t.
19944 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19945 Back then I didn't know that the Emacs coding style prefers signed int.
19946 Also, in the meantime I found a few more instances where arguments
19947 were being counted with int, which may truncate counts on 64-bit
19948 machines, or EMACS_INT, which may be unnecessarily wide.
19949 * lisp.h (struct Lisp_Subr.function.aMANY)
19950 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19951 Arg counts are now ptrdiff_t, not size_t.
19952 All variadic functions and their callers changed accordingly.
19953 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19954 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19955 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19956 * callint.c (Fcall_interactively): Check arg count for overflow,
19957 to avoid potential buffer overrun. Use signed char, not 'int',
19958 for 'varies' array, so that we needn't bother to check its size
19959 calculation for overflow.
19960 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19961 * eval.c (apply_lambda):
19962 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19963 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19964 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19966 * callint.c (Fcall_interactively): Don't use index var as event count.
19968 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19969 * mem-limits.h (SIZE): Remove; no longer used.
19971 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19973 Remove unnecessary casts.
19974 * xterm.c (x_term_init):
19975 * xfns.c (x_set_border_pixel):
19976 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19977 These aren't needed now that we assume ANSI C.
19979 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19980 It's more likely to cause problems (due to unsigned overflow)
19983 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19985 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19987 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19989 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19991 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19993 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19995 GLYPH_CODE_FACE returns EMACS_INT, not int.
19996 * dispextern.h (merge_faces):
19997 * xfaces.c (merge_faces):
19998 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19999 Don't assume EMACS_INT fits in int.
20001 * character.h (CHAR_VALID_P): Remove unused parameter.
20002 * fontset.c, lisp.h, xdisp.c: All uses changed.
20004 * editfns.c (Ftranslate_region_internal): Omit redundant test.
20006 * fns.c (concat): Minor tuning based on overflow analysis.
20007 This doesn't fix any bugs. Use int to hold character, instead
20008 of constantly refetching from Emacs object. Use XFASTINT, not
20009 XINT, for value known to be a character. Don't bother comparing
20010 a single byte to 0400, as it's always less.
20012 * floatfns.c (Fexpt):
20013 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
20015 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
20018 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
20020 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
20021 Without this fix, on a 64-bit host (aset S 0 4294967386) would
20022 incorrectly succeed when S was a string, because 4294967386 was
20023 truncated before it was used.
20025 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
20026 Otherwise, an out-of-range integer could cause undefined behavior
20029 * composite.c: Use int, not EMACS_INT, for characters.
20030 (fill_gstring_body, composition_compute_stop_pos): Use int, not
20031 EMACS_INT, for values that are known to be in character range.
20032 This doesn't fix any bugs but is the usual style inside Emacs and
20033 may generate better code on 32-bit machines.
20035 Make sure a 64-bit char is never passed to ENCODE_CHAR.
20036 This is for reasons similar to the recent CHAR_STRING fix.
20037 * charset.c (Fencode_char): Check that character arg is actually
20038 a character. Pass an int to ENCODE_CHAR.
20039 * charset.h (ENCODE_CHAR): Verify that the character argument is no
20040 wider than 'int', as a compile-time check to prevent future regressions
20043 * character.c (char_string): Remove unnecessary casts.
20045 Make sure a 64-bit char is never passed to CHAR_STRING.
20046 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
20047 by silently ignoring the top 32 bits, allowing some values
20048 that were far too large to be valid characters.
20049 * character.h: Include <verify.h>.
20050 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
20051 arguments are no wider than unsigned, as a compile-time check
20052 to prevent future regressions in this area.
20054 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
20055 (Fsubst_char_in_region):
20057 * xdisp.c (decode_mode_spec_coding):
20058 Adjust to CHAR_STRING's new requirement.
20059 * editfns.c (Finsert_char, Fsubst_char_in_region):
20060 * fns.c (concat): Check that character args are actually
20061 characters. Without this test, these functions did the wrong
20062 thing with wildly out-of-range values on 64-bit hosts.
20064 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
20065 These casts should not be needed on 32-bit hosts, either.
20066 * keyboard.c (read_char):
20067 * lread.c (Fload): Remove casts to unsigned.
20069 * lisp.h (UNSIGNED_CMP): New macro.
20070 This fixes comparison bugs on 64-bit hosts.
20071 (ASCII_CHAR_P): Use it.
20072 * casefiddle.c (casify_object):
20073 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
20074 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
20075 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
20076 * dispextern.h (FACE_FROM_ID):
20077 * keyboard.c (read_char): Use UNSIGNED_CMP.
20079 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
20080 not to EMACS_INT, to avoid GCC warning.
20082 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
20084 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
20085 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
20086 isn't needed on 32-bit machines.
20088 * buffer.c (Fgenerate_new_buffer_name):
20089 Use EMACS_INT for count, not int.
20090 (advance_to_char_boundary): Return EMACS_INT, not int.
20092 * data.c (Qcompiled_function): Now static.
20094 * window.c (window_body_lines): Now static.
20096 * image.c (gif_load): Rename local to avoid shadowing.
20098 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
20099 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
20100 * alloc.c (make_save_value): Integer argument is now of type
20101 ptrdiff_t, not int.
20102 (mark_object): Use ptrdiff_t, not int.
20103 * lisp.h (pD): New macro.
20104 * print.c (print_object): Use it.
20106 * alloc.c: Use EMACS_INT, not int, to count objects.
20107 (total_conses, total_markers, total_symbols, total_vector_size)
20108 (total_free_conses, total_free_markers, total_free_symbols)
20109 (total_free_floats, total_floats, total_free_intervals)
20110 (total_intervals, total_strings, total_free_strings):
20111 Now EMACS_INT, not int. All uses changed.
20112 (Fgarbage_collect): Compute overall total using a double, so that
20113 integer overflow is less likely to be a problem. Check for overflow
20114 when converting back to an integer.
20115 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
20116 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
20117 These were 'int' variables that could overflow on 64-bit hosts;
20118 they were never used, so remove them instead of repairing them.
20119 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
20120 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
20121 Previously, this ceilinged at INT_MAX, but that doesn't work on
20123 (allocate_pseudovector): Don't use EMACS_INT when int would do.
20125 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
20126 (allocate_vectorlike): Check for ptrdiff_t overflow.
20127 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
20128 when a (possibly-narrower) signed value would do just as well.
20129 We prefer using signed arithmetic, to avoid comparison confusion.
20131 * alloc.c: Catch some string size overflows that we were missing.
20132 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
20133 for convenience in STRING_BYTES_MAX.
20134 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
20135 The definition here is exact; the one in lisp.h was approximate.
20136 (allocate_string_data): Check for string overflow. This catches
20137 some instances we weren't catching before. Also, it catches
20138 size_t overflow on (unusual) hosts where SIZE_MAX <= min
20139 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
20140 and ptrdiff_t and EMACS_INT are both 64 bits.
20142 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
20143 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
20144 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
20146 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
20148 * alloc.c (Fmake_string): Check for out-of-range init.
20150 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
20152 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
20154 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
20156 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
20157 xg_get_default_scrollbar_width.
20159 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
20160 (int_gtk_range_get_value): Move to the scroll bar part of the file.
20161 (style_changed_cb): Call update_theme_scrollbar_width and call
20162 x_set_scroll_bar_default_width and xg_frame_set_char_size for
20163 all frames (Bug#8505).
20164 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
20165 Call gtk_window_set_resizable if HAVE_GTK3.
20166 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
20167 and height if HAVE_GTK3 (Bug#8505).
20168 (scroll_bar_width_for_theme): New variable.
20169 (update_theme_scrollbar_width): New function.
20170 (xg_get_default_scrollbar_width): Move code to
20171 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
20172 (xg_initialize): Call update_theme_scrollbar_width.
20174 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
20176 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
20178 2011-06-12 Martin Rudalics <rudalics@gmx.at>
20180 * frame.c (make_frame): Call other_buffer_safely instead of
20183 * window.c (temp_output_buffer_show): Call display_buffer with
20184 second argument Vtemp_buffer_show_specifiers and reset latter
20185 immediately after the call.
20186 (Vtemp_buffer_show_specifiers): New variable.
20187 (auto_window_vscroll_p, next_screen_context_lines)
20188 (Vscroll_preserve_screen_position): Remove leading asterisks from

20371 Remove static from declaration of Qdelete_window, it's
20372 temporarily needed by Fbury_buffer.
20373 (replace_window): Don't assign orig_top_line and

20378 Replace Fdelete_window calls with calls to Qdelete_window.
20379 (Fdelete_other_windows): Remove. Deleting other windows is

20739 (display_prop_intangible_p): Reimplement to call
20740 handle_display_spec instead of single_display_spec_intangible_p.

20752 value of a `display' property is a "replacing spec".
20753 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
20754 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

20784 * gnutls.c: Use Emacs's memory allocators.
20785 Without this change, the gnutls library would invoke malloc etc.
20786 directly, which causes problems on non-SYNC_INPUT hosts, and which
20787 runs afoul of improving memory_full behavior. (Bug#8761)
20788 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20789 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20790 xfree instead of the default malloc, realloc, free.
20791 (Fgnutls_boot): No need to check for memory allocation failure,
20792 since xmalloc does that for us.

20821 need to be updated by these changes.
20822 * fns.c (make_hash_table, maybe_resize_hash_table):
20823 Check for integer overflow with large hash tables.
20824 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20825 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20826 (SXHASH_REDUCE): New macro.
20827 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20828 Use it instead of discarding useful hash info with large hash values.
20829 (sxhash_float): New function.
20830 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20831 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20832 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20833 Rewrite to use FIXNUM_BITS, as this simplifies things.
20834 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20835 Adjust signatures to match updated version of code.
20836 (consing_since_gc): Now EMACS_INT, since a single hash table can
20837 use more than INT_MAX bytes.

20860 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20862 Don't force ./temacs to start in terminal mode.
20864 * frame.c (make_initial_frame): Initialize faces in all cases, not
20865 only when CANNOT_DUMP is defined.
20866 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
20868 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20870 * dispnew.c (add_window_display_history): Use const for the string
20871 pointer. Remove declaration, not needed.
20873 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20875 Use 'inline', not 'INLINE'.
20876 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20877 * alloc.c, fontset.c (INLINE): Remove.
20878 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20879 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20880 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20881 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20882 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20884 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20886 Make it possible to run ./temacs.
20888 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20889 syms_of_callproc does the same thing. Remove test for
20890 "initialized", do it in the caller.
20891 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20893 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20895 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20896 (read_minibuf): Use get_minibuffer.
20897 (syms_of_minibuf): Use DEFSYM.
20898 (Qmetadata): New var.
20899 * data.c (Qbuffer): Don't make it static.
20900 (syms_of_data): Use DEFSYM.
20902 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20904 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20905 (CCL_CODE_MIN): New macro.
20907 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20909 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20911 * eval.c (Qdebug): Now static.
20912 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20913 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20914 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20916 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20918 * image.c: Various fixes to ImageMagick code comments.
20919 (Fimagemagick_types): Doc fix.
20921 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20923 Minor fixes prompted by GCC 4.6.0 warnings.
20925 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20927 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20928 (x_clipboard_manager_save_all): Move extern decl to ...
20929 * xterm.h: ... here, so that it can be checked for consistency.
20931 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20933 * xselect.c (x_clipboard_manager_save_frame)
20934 (x_clipboard_manager_save_all): New functions.
20935 (Fx_clipboard_manager_save): Lisp function deleted.
20937 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20938 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20940 * xterm.h: Update prototype.
20942 2011-05-28 William Xu <william.xwl@gmail.com>
20944 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20945 exiting (Bug#8239).
20947 2011-05-28 Jim Meyering <meyering@redhat.com>
20949 Avoid a sign-extension bug in crypto_hash_function.
20950 * fns.c (to_uchar): Define.
20951 (crypto_hash_function): Use it to convert some newly-signed
20952 variables to unsigned, to avoid sign-extension bugs. For example,
20953 without this change, (md5 "truc") would evaluate to
20954 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20955 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20956 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20958 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20960 Integer overflow fixes.
20962 * dbusbind.c: Serial number integer overflow fixes.
20963 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20964 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20965 to hold a serial number that is too large for a fixnum.
20966 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20967 Check for serial numbers out of range. Decode any serial number
20968 that was so large that it became a float. (Bug#8722)
20970 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20971 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20972 Use XFASTINT rather than XUINT when numbers are nonnegative.
20973 (xd_append_arg, Fdbus_method_return_internal):
20974 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20975 arguments, check that Lisp number is nonnegative, rather than
20976 silently wrapping negative numbers around. (Bug#8722)
20977 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20980 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20982 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20984 ccl: Add integer overflow checks.
20985 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20986 (IN_INT_RANGE): New macros.
20987 (ccl_driver): Use them to check for integer overflow when
20988 decoding a CCL program. Many of the new checks are whether XINT (x)
20989 fits in int; it doesn't always, on 64-bit hosts. The new version
20990 doesn't catch all possible integer overflows, but it's an
20991 improvement. (Bug#8719)
20993 * alloc.c (make_event_array): Use XINT, not XUINT.
20994 There's no need for unsigned here.
20996 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20997 This follows up to the 2011-05-06 change that substituted uintptr_t
20998 for EMACS_INT. This case wasn't caught back then.
21000 Rework Fformat to avoid integer overflow issues.
21001 * editfns.c: Include <float.h> unconditionally, as it's everywhere
21002 now (part of C89). Include <verify.h>.
21003 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
21004 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
21005 (Fformat): Avoid the prepass trying to compute sizes; it was only
21006 approximate and thus did not catch overflow reliably. Instead, walk
21007 through the format just once, formatting and computing sizes as we go,
21008 checking for integer overflow at every step, and allocating a larger
21009 buffer as needed. Keep track separately whether the format is
21010 multibyte. Keep only the most-recently calculated precision, rather
21011 than them all. Record whether each argument has been converted to
21012 string. Use EMACS_INT, not int, for byte and char and arg counts.
21013 Support field widths and precisions larger than INT_MAX. Avoid
21014 sprintf's undefined behavior with conversion specifications such as %#d
21015 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
21016 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
21017 formatting out-of-range floating point numbers with int
21018 formats. (Bug#8668)
21020 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
21022 * data.c: Avoid integer truncation in expressions involving floats.
21023 * data.c: Include <intprops.h>.
21024 (arith_driver): When there's an integer overflow in an expression
21025 involving floating point, convert the integers to floating point
21026 so that the resulting value does not suffer from catastrophic
21027 integer truncation. For example, on a 64-bit host (* 4
21028 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
21029 Do not rely on undefined behavior after integer overflow.
21031 merge count_size_as_multibyte, parse_str_to_multibyte
21032 * character.c, character.h (count_size_as_multibyte):
21033 Rename from parse_str_to_multibyte; all uses changed.
21034 Check for integer overflow.
21035 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
21036 since it's now a duplicate of the other. This is more of
21037 a character than a buffer op, so better that it's in character.c.
21038 * fns.c, print.c: Adjust to above changes.
21040 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
21042 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
21044 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
21046 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
21047 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
21048 (x_clipboard_manager_save): Now static.
21049 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
21051 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
21052 (crypto_hash_function): Now static.
21053 Fix pointer signedness problems. Avoid unnecessary initializations.
21055 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
21057 * termhooks.h (Vselection_alist): Make it terminal-local.
21059 * terminal.c (create_terminal): Initialize it.
21061 * xselect.c: Support for clipboard managers.
21062 (Vselection_alist): Move to termhooks.h as terminal-local var.
21063 (LOCAL_SELECTION): New macro.
21064 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
21065 (symbol_to_x_atom): Remove gratuitous arg.
21066 (x_handle_selection_request, lisp_data_to_selection_data)
21067 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
21068 (x_own_selection, x_get_local_selection, x_convert_selection):
21069 New arg, specifying work frame. Use terminal-local Vselection_alist.
21070 (some_frame_on_display): Delete unused function.
21071 (Fx_own_selection_internal, Fx_get_selection_internal)
21072 (Fx_disown_selection_internal, Fx_selection_owner_p)
21073 (Fx_selection_exists_p): New optional frame arg.
21074 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
21075 (x_handle_selection_clear): Don't treat other terminals with the
21076 same keyboard specially. Use the terminal-local Vselection_alist.
21077 (x_clear_frame_selections): Use Frun_hook_with_args.
21079 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
21081 * xterm.h: Add support for those atoms.
21083 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
21085 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
21086 (converted_selections, conversion_fail_tag): New global variables.
21087 (x_selection_request_lisp_error): Free the above.
21088 (x_get_local_selection): Remove unnecessary code.
21089 (x_reply_selection_request): Args changed; handle arbitrary array
21090 of converted selections stored in converted_selections.
21091 Separate the XChangeProperty and SelectionNotify steps.
21092 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
21093 (x_convert_selection): New function.
21094 (x_handle_selection_event): Simplify.
21095 (x_get_foreign_selection): Don't ignore incoming requests while
21096 waiting for an answer; this will fail when we implement
21097 SAVE_TARGETS, and seems unnecessary anyway.
21098 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
21099 (Vx_sent_selection_functions): Doc fix.
21101 2011-05-26 Leo Liu <sdl.web@gmail.com>
21103 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
21105 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21107 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
21109 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
21110 for fringe update if it has periodic bitmap.
21111 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
21112 and fringe_bitmap_periodic_p.
21114 * fringe.c (get_fringe_bitmap_data): New function.
21115 (draw_fringe_bitmap_1, update_window_fringes): Use it.
21116 (update_window_fringes): Record periodicity of fringe bitmap in glyph
21117 row. Mark glyph row for fringe update if periodicity changed.
21119 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
21120 for fringe update unless it has periodic bitmap.
21122 2011-05-25 Kenichi Handa <handa@m17n.org>
21124 * xdisp.c (get_next_display_element): Set correct it->face_id for
21125 a static composition.
21127 2011-05-24 Leo Liu <sdl.web@gmail.com>
21130 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
21132 * fns.c (crypto_hash_function, Fsha1): New function.
21133 (Fmd5): Use crypto_hash_function.
21134 (syms_of_fns): Add Ssha1.
21136 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
21138 * gnutls.c: Remove unused macros.
21139 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
21140 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
21141 Remove macros that are defined and never used.
21142 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
21144 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
21146 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
21147 (Fx_get_selection_internal): Minor cleanup.
21148 (Fx_own_selection_internal): Rename arguments for consistency with
21151 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
21153 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
21155 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
21157 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
21159 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21161 * dispnew.c (scrolling_window): Don't exclude the case that the
21162 last enabled row in the desired matrix touches the bottom boundary.
21164 2011-05-21 Glenn Morris <rgm@gnu.org>
21166 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
21167 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
21168 and add some more files.
21170 2011-05-20 Eli Zaretskii <eliz@gnu.org>
21172 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
21173 report_file_error introduced by the change from 2011-05-07.
21175 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
21177 * systime.h (Time): Define only if emacs is defined.
21178 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
21179 where the include path doesn't have X11/X.h by default. See
21180 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
21182 2011-05-20 Kenichi Handa <handa@m17n.org>
21184 * composite.c (find_automatic_composition): Fix previous change.
21186 2011-05-20 Glenn Morris <rgm@gnu.org>
21188 * lisp.mk: New file, split from Makefile.in.
21189 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
21190 (shortlisp): Remove.
21191 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
21193 2011-05-19 Glenn Morris <rgm@gnu.org>
21195 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
21196 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
21197 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
21198 (lisp): Set the order to that of loadup.el.
21199 (shortlisp): Make it a copy of $lisp.
21200 (SOME_MACHINE_LISP): Remove.
21201 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
21202 Use just $shortlisp, not $SOME_MACHINE_LISP too.
21204 2011-05-18 Kenichi Handa <handa@m17n.org>
21206 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
21207 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
21208 (find_automatic_composition): Mostly rewrite for efficiency.
21210 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
21212 * makefile.w32-in: Update dependencies.
21214 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
21216 * menu.c: Include limits.h (fixes the MS-Windows build broken by
21217 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
21219 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
21221 Fix some integer overflow issues, such as string length overflow.
21223 * insdel.c (count_size_as_multibyte): Check for string overflow.
21225 * character.c (lisp_string_width): Check for string overflow.
21226 Use EMACS_INT, not int, for string indexes and lengths; in
21227 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
21228 the resulting string length overflows an EMACS_INT; instead,
21229 report a string overflow if no precision given. When checking for
21230 precision exhaustion, use a check that cannot possibly have
21231 integer overflow. (Bug#8675)
21232 * character.h (lisp_string_width): Adjust to new signature.
21234 * alloc.c (string_overflow): New function.
21235 (Fmake_string): Use it. This doesn't change behavior, but saves
21236 a few bytes and will simplify future changes.
21237 * character.c (string_escape_byte8): Likewise.
21238 * lisp.h (string_overflow): New decl.
21240 Fixups, following up to the user-interface timestamp change.
21241 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
21242 for UI timestamps, instead of unsigned long.
21243 * msdos.c (mouse_get_pos): Likewise.
21244 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
21245 * w32gui.h (Time): Define by including "systime.h" rather than by
21246 declaring it ourselves. (Bug#8664)
21248 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
21249 * image.c (clear_image_cache): Likewise.
21251 * term.c (term_mouse_position): Don't assume time_t wraparound.
21253 Be more systematic about user-interface timestamps.
21254 Before, the code sometimes used 'Time', sometimes 'unsigned long',
21255 and sometimes 'EMACS_UINT', to represent these timestamps.
21256 This change causes it to use 'Time' uniformly, as that's what X uses.
21257 This makes the code easier to follow, and makes it easier to catch
21258 integer overflow bugs such as Bug#8664.
21259 * frame.c (Fmouse_position, Fmouse_pixel_position):
21260 Use Time, not unsigned long, for user-interface timestamps.
21261 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
21262 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
21263 * keyboard.h (last_event_timestamp): Likewise.
21264 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
21265 * menu.h (xmenu_show): Likewise.
21266 * term.c (term_mouse_position): Likewise.
21267 * termhooks.h (struct input_event.timestamp): Likewise.
21268 (struct terminal.mouse_position_hook): Likewise.
21269 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
21270 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
21271 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
21272 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
21273 what it was before.
21274 * menu.h, termhooks.h: Include "systime.h", for Time.
21276 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
21277 Don't assume that the difference between two unsigned long values
21278 can fit into an integer. At this point, we know button_down_time
21279 <= event->timestamp, so the difference must be nonnegative, so
21280 there's no need to cast the result if double-click-time is
21281 nonnegative, as it should be; check that it's nonnegative, just in
21282 case. This bug is triggered when events are more than 2**31 ms
21283 apart (about 25 days). (Bug#8664)
21285 * xselect.c (last_event_timestamp): Remove duplicate decl.
21286 (x_own_selection): Remove needless cast to unsigned long.
21288 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
21289 that always fit in int. Use a sentinel instead of a counter, to
21290 avoid a temp and to allay GCC's concerns about possible int overflow.
21291 * frame.h (struct frame): Use int for menu_bar_items_used
21292 instead of EMACS_INT, since it always fits in int.
21294 * menu.c (grow_menu_items): Check for int overflow.
21296 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
21298 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
21299 Before, the code was not consistent. These values cannot exceed
21300 2**31 - 1 so there's no need to make them unsigned.
21301 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
21302 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
21303 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
21305 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
21307 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
21308 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
21309 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
21310 presumably because the widths might not match.
21312 * window.c (size_window): Avoid needless test at loop start.
21314 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
21316 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
21318 2011-05-12 Drew Adams <drew.adams@oracle.com>
21320 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
21322 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
21324 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
21325 `width' to `bar_area_x' and `bar_area_width', respectively.
21326 (x_scroll_run): Take account of fringe background extension.
21328 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
21329 Rename local vars `left' and `width' to `bar_area_x' and
21330 `bar_area_width', respectively.
21331 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
21332 background extension.
21334 2011-05-10 Jim Meyering <meyering@redhat.com>
21336 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
21338 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
21340 * image.c (Finit_image_library): Return t for built-in image types,
21341 like pbm and xbm. (Bug#8640)
21343 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
21345 * w32menu.c (set_frame_menubar): Fix submenu allocation.
21347 2011-05-07 Eli Zaretskii <eliz@gnu.org>
21349 * w32console.c (Fset_screen_color): Doc fix.
21350 (Fget_screen_color): New function.
21351 (syms_of_ntterm): Defsubr it.
21353 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
21354 unlink the temporary file if Fcall_process didn't create it in the
21356 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
21357 child process will be redirected to a file specified with `:file'.
21358 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
21359 cue to call_process_cleanup not to close that handle.
21361 2011-05-07 Ben Key <bkey76@gmail.com>
21363 * makefile.w32-in: The bootstrap-temacs rule now makes use of
21364 one of two shell specific rules, either bootstrap-temacs-CMD or
21365 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
21366 to the previous implementation of the bootstrap-temacs rule.
21367 The bootstrap-temacs-CMD rule is similar to the previous
21368 implementation of the bootstrap-temacs rule except that it
21369 makes use of the ESC_CFLAGS variable instead of the CFLAGS
21372 These changes, along with some changes to nt/configure.bat,
21373 nt/gmake.defs, and nt/nmake.defs, are required to extend my
21374 earlier fix to add support for --cflags and --ldflags options
21375 that include quotes so that it works whether make uses cmd or
21378 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
21380 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
21381 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
21383 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
21384 a string. Handle both cases.
21385 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
21386 (Fdbus_register_method): Use Qinvalid_function.
21388 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21390 * makefile.w32-in: Update dependencies.
21391 (LISP_H): Add inttypes.h and stdin.h.
21392 (PROCESS_H): Add unistd.h.
21394 2011-05-06 Eli Zaretskii <eliz@gnu.org>
21396 * lread.c: Include limits.h (fixes the MS-Windows build broken by
21397 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
21399 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
21401 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
21403 * term.c (vfatal): Remove stray call to va_end.
21404 It's not needed and the C Standard doesn't allow it here anyway.
21406 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
21407 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
21409 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
21412 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
21414 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
21416 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
21418 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
21420 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
21422 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
21423 * charset.c (Fdefine_charset_internal): Don't initialize
21424 charset.code_space[15]. The value was garbage, on hosts with
21425 32-bit int (Bug#8600).
21427 * lread.c (read_integer): Be more consistent with string-to-number.
21428 Use string_to_number to do the actual conversion; this avoids
21429 rounding errors and fixes some other screwups. Without this fix,
21430 for example, #x1fffffffffffffff was misread as -2305843009213693952.
21431 (digit_to_number): Move earlier, for benefit of read_integer.
21432 Return -1 if the digit is out of range for the base, -2 if it is
21433 not a digit in any supported base. (Bug#8602)
21435 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
21437 * dispnew.c (scrolling_window): Return 1 if we scrolled,
21438 to match comment at start of function. This also removes a
21439 GCC warning about overflow in a 32+64-bit port.
21441 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
21443 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
21444 Reported by Stefan Monnier in
21445 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
21446 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21447 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
21449 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
21450 (EMACS_UINTPTR): Likewise, with uintptr_t.
21452 * lisp.h: Prefer 64-bit EMACS_INT if available.
21453 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
21454 on 32-bit hosts that have 64-bit int, so that they can access
21456 However, temporarily disable this change unless the temporary
21457 symbol WIDE_EMACS_INT is defined.
21459 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
21461 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
21462 This removes an assumption that EMACS_INT and long are the same
21463 width as pointers. The assumption is true for Emacs porting targets
21464 now, but we want to make other targets possible.
21465 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
21466 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
21467 In the rest of the code, change types of integers that hold casted
21468 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
21469 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
21470 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
21471 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
21472 No need to cast type when ORing.
21473 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
21474 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
21475 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
21476 assume EMACS_INT is the same width as char *.
21477 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
21478 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
21479 Remove no-longer-needed casts.
21480 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
21481 (xg_tool_bar_help_callback, xg_make_tool_item):
21482 Use EMACS_INTPTR to hold an integer
21483 that will be cast to void *; this can avoid a GCC warning
21484 if EMACS_INT is not the same width as void *.
21485 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
21486 * xdisp.c (display_echo_area_1, resize_mini_window_1):
21487 (current_message_1, set_message_1):
21488 Use a local to convert to proper width without a cast.
21489 * xmenu.c (dialog_selection_callback): Likewise.
21491 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
21492 Also, don't assume VALBITS / RAND_BITS is less than 5,
21493 and don't rely on undefined behavior when shifting a 1 left into
21495 * lisp.h (get_random): Change signature to match.
21497 * lread.c (hash_string): Use size_t, not int, for hash computation.
21498 Normally we prefer signed values; but hashing is special, because
21499 it's better to use unsigned division on hash table sizes so that
21500 the remainder is nonnegative. Also, size_t is the natural width
21501 for hashing into memory. The previous code used 'int', which doesn't
21502 retain enough info to hash well into very large tables.
21503 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
21505 * dbusbind.c: Don't possibly lose pointer info when converting.
21506 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21507 Use XPNTR rather than XHASH, so that the high-order bits of
21508 the pointer aren't lost when converting through void *.
21510 * eval.c (Fautoload): Don't double-shift a pointer.
21512 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
21514 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21516 * gnutls.c (DEF_GNUTLS_FN):
21517 * image.c (DEF_IMGLIB_FN): Make function pointers static.
21519 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
21521 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
21524 2011-05-05 Eli Zaretskii <eliz@gnu.org>
21526 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
21527 New version that can reserve upto 2GB of heap space.
21529 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
21531 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
21533 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
21535 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
21536 `gnutls_certificate_set_x509_key_file'.
21538 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
21540 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
21541 Update dependencies.
21543 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21545 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
21546 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
21547 Remove unused parameter `fildes'.
21548 * process.c (read_process_output, send_process): Don't pass it.
21550 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21552 Fix previous change: the library cache is defined in w32.c.
21553 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
21554 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
21556 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21558 Implement dynamic loading of GnuTLS on Windows.
21560 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
21561 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
21562 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21565 * gnutls.c (Qgnutls_dll): Define.
21566 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
21567 (gnutls_*): Declare function pointers.
21568 (init_gnutls_functions): New function to initialize function pointers.
21569 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
21570 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
21571 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21572 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
21573 (emacs_gnutls_write, emacs_gnutls_read)
21574 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
21575 (Fgnutls_available_p): New function.
21576 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
21577 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
21578 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
21580 * image.c: Include w32.h.
21581 (Vimage_type_cache): Delete.
21582 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
21583 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
21584 (w32_delayed_load): Move to w32.c.
21586 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
21588 * w32.c (QCloaded_from, Vlibrary_cache): Define.
21589 (w32_delayed_load): Move from image.c. When loading a library, record
21590 its filename in the :loaded-from property of the library id.
21591 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
21592 Initialize and staticpro them.
21593 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
21595 * process.c: Include lisp.h before w32.h, not after.
21596 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
21597 instead of gnutls_record_check_pending.
21599 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
21601 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
21603 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
21604 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
21607 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
21609 * xterm.c (x_set_frame_alpha): Do not set property on anything
21610 else than FRAME_X_OUTER_WINDOW (Bug#8608).

21630 * callproc.c: Indentation fixup.
21632 * sysdep.c (wait_for_termination_1): Make static.
21633 (wait_for_termination, interruptible_wait_for_termination):
21634 Move after wait_for_termination_1.
21636 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
21638 * sysdep.c (interruptible_wait_for_termination): New function
21639 which is like wait_for_termination, but allows keyboard
21642 * callproc.c (Fcall_process): Add (:file "file") as an option for
21644 (Fcall_process_region): Ditto.
21646 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21648 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21649 rather than `XVECTOR (FOO)->size'.
21651 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21652 inttypes.h, as a gnulib replacement is used if it not available in
21655 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21657 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21658 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21659 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21661 * coding.c (coding_alloc_by_realloc): Error out if destination
21662 will grow beyond MOST_POSITIVE_FIXNUM.
21663 (decode_coding_emacs_mule): Abort if there isn't enough place in
21664 charbuf for the composition carryover bytes. Reserve an extra

21673 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21674 %llo or %llx format is passed. (Bug#8545)
21676 * window.c (window_scroll_line_based): Use a marker instead of
21677 simple variables to record original value of point. (Bug#7952)
21679 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21680 produced by %s or %c overflows available buffer space. (Bug#8545)
21682 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21684 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21685 (SIZE_MAX): Move defn after all includes, as they might #define it.
21687 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21689 * w32.c (init_environment): Warn about defaulting HOME to C:\.

21709 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21711 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21713 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21715 * makefile.w32-in: Update dependencies.
21717 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21719 Improve `doprnt' and its usage. (Bug#8545)
21720 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21721 `format_end'. Remove support for %l as a conversion specifier.
21722 Don't use xrealloc. Improve diagnostics when the %l size modifier
21723 is used. Update the commentary.
21725 * eval.c (verror): Simplify calculation of size_t.
21727 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21730 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21732 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21735 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21737 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21738 This makes this file independent of the recent pseudovector change.
21740 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21742 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21744 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21745 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21746 Remove unused local.
21747 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21749 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21750 GCC 4.6.0 optimizes based on type-based alias analysis.
21751 For example, if b is of type struct buffer * and v of type struct
21752 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21753 != &v->size, and therefore "v->size = 1; b->size = 2; return
21754 v->size;" must therefore return 1. This assumption is incorrect
21755 for Emacs, since it type-puns struct Lisp_Vector * with many other
21756 types. To fix this problem, this patch adds a new type struct
21757 vectorlike_header that documents the constraints on layout of vectors
21758 and pseudovectors, and helps optimizing compilers not get fooled
21759 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21760 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21761 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21763 (XSETPVECTYPE): Rewrite in terms of new macro.
21764 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21765 This is a bit clearer, and further avoids the possibility of
21766 undesirable aliasing.
21767 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21768 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21769 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21770 since Lisp_Subr is a special case (no "next" field).
21771 (ASIZE): Now uses header.size rather than size.
21772 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21773 to avoid the hassle of writing XVECTOR (foo)->header.size.
21774 (struct vectorlike_header): New type.
21775 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21776 object, to help avoid aliasing.
21777 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21778 (SUBRP): Likewise, since Lisp_Subr is a special case.
21779 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21780 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21781 (struct Lisp_Hash_Table): Combine first two members into a single
21782 struct vectorlike_header member. All uses of "size" and "next" members
21783 changed to be "header.size" and "header.next".
21784 * buffer.h (struct buffer): Likewise.
21785 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21786 * frame.h (struct frame): Likewise.
21787 * process.h (struct Lisp_Process): Likewise.
21788 * termhooks.h (struct terminal): Likewise.
21789 * window.c (struct save_window_data, struct saved_window): Likewise.
21790 * window.h (struct window): Likewise.
21791 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21792 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21793 * buffer.c (init_buffer_once): Likewise.
21794 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21796 * process.c (Fformat_network_address): Use local var for size,
21799 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21801 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21802 * data.c (atof): Remove decl; no longer used or needed.
21803 (digit_to_number): Move to lread.c.
21804 (Fstring_to_number): Use new string_to_number function, to be
21805 consistent with how the Lisp reader treats infinities and NaNs.
21806 Do not assume that floating-point numbers represent EMACS_INT
21807 without losing information; this is not true on most 64-bit hosts.
21808 Avoid double-rounding errors, by insisting on integers when
21809 parsing non-base-10 numbers, as the documentation specifies.
21810 * lisp.h (string_to_number): New decl, replacing ...
21811 (isfloat_string): Remove.
21812 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21813 (read1): Do not accept +. and -. as integers; this
21814 appears to have been a coding error. Similarly, do not accept
21815 strings like +-1e0 as floating point numbers. Do not report
21816 overflow for integer overflows unless the base is not 10 which
21817 means we have no simple and reliable way to continue.
21818 Break out the floating-point parsing into a new
21819 function string_to_number, so that Fstring_to_number parses
21820 floating point numbers consistently with the Lisp reader.
21821 (digit_to_number): Move here from data.c. Make it static inline.
21822 (E_CHAR, EXP_INT): Remove, replacing with ...
21823 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21824 (string_to_number): New function, replacing isfloat_string.
21825 This function checks for valid syntax and produces the resulting
21826 Lisp float number too. Rework it so that string-to-number
21827 no longer mishandles examples like "1.0e+". Use strtoumax,
21828 so that overflow for non-base-10 numbers is reported only when
21829 there's no portable and simple way to convert to floating point.
21831 * textprop.c (set_text_properties_1): Rewrite for clarity,
21832 and to avoid GCC warning about integer overflow.
21834 * intervals.h (struct interval): Use EMACS_INT for members
21835 where EMACS_UINT might cause problems. See
21836 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21837 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21838 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21840 (offset_intervals): Tell GCC not to worry about length overflow
21841 when negating a negative length.
21843 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21844 (overrun_check_free): Likewise.
21846 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21847 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21850 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21851 (gnutls_make_error): Rename local to avoid shadowing.
21852 (gnutls_emacs_global_deinit): ifdef out; not used.
21853 (Fgnutls_boot): Use const for pointer to readonly storage.
21854 Comment out unused local. Fix pointer signedness problems.
21856 * lread.c (openp): Don't stuff size_t into an 'int'.
21857 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21858 about possible signed overflow.
21860 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21861 (GDK_KEY_g): Don't define if already defined.
21862 (xg_prepare_tooltip): Avoid pointer signedness problem.
21863 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21865 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21866 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21868 * xfns.c (Fx_window_property): Simplify a bit,
21869 to make a bit faster and to avoid GCC 4.6.0 warning.
21870 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21872 * fns.c (internal_equal): Don't assume size_t fits in int.
21874 * alloc.c (compact_small_strings): Tighten assertion a little.
21876 Replace pEd with more-general pI, and fix some printf arg casts.
21877 * lisp.h (pI): New macro, generalizing old pEd macro to other
21878 conversion specifiers. For example, use "...%"pI"d..." rather
21879 than "...%"pEd"...".
21880 (pEd): Remove. All uses replaced with similar uses of pI.
21881 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21882 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21883 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21884 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21885 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21886 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21887 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21889 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21890 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21891 * print.c (safe_debug_print, print_object): Likewise.
21892 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21894 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21895 avoiding the 0 flag, which is not portable.
21896 * process.c (Fmake_network_process): Use pI to avoid cast.
21897 * region-cache.c (pp_cache): Likewise.
21898 * xdisp.c (decode_mode_spec): Likewise.
21899 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21900 behavior on 64-bit hosts with printf arg.
21901 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21902 (x_stop_queuing_selection_requests): Likewise.
21903 (x_get_window_property): Don't truncate byte count to an 'int'
21906 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21907 here, since it parses constructs like leading '-' and spaces,
21908 which are not wanted; and it overflows with large numbers.
21909 Instead, simply match F[0-9]+, which is what is wanted anyway.
21911 * alloc.c: Remove unportable assumptions about struct layout.
21912 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21913 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21914 (allocate_vectorlike, make_pure_vector): Use the new macros,
21915 plus offsetof, to remove unportable assumptions about struct layout.
21916 These assumptions hold on all porting targets that I know of, but
21917 they are not guaranteed, they're easy to remove, and removing them
21918 makes further changes easier.
21920 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21921 This doesn't fix a bug but makes the code clearer.
21922 (string_overrun_cookie): Now const. Use initializers that
21923 don't formally overflow signed char, to avoid warnings.
21924 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21925 can cause Emacs to crash when string overrun checking is enabled.
21926 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21927 multiple of sizeof (EMACS_INT); it need not be, if
21928 alignof(EMACS_INT) < sizeof (EMACS_INT).
21929 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21931 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

21938 supposed to be handshaking. (Bug#8556)
21939 Reported by Paul Eggert <eggert@cs.ucla.edu>.
21941 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
21943 * lisp.h (Qdebug): List symbol.
21944 * eval.c (Qdebug): Restore global linkage.

21951 * alloc.c (check_sblock, check_string_bytes)
21952 (check_string_free_list): Convert to standard C.
21954 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
21956 * w32.c (emacs_gnutls_push): Fix typo.
21958 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21960 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21961 "cast to pointer from integer of different size".
21963 Improve doprnt and its use in verror. (Bug#8545)
21964 * doprnt.c (doprnt): Document the set of format control sequences
21965 supported by the function. Use SAFE_ALLOCA instead of always
21968 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21969 is one byte too soon. Don't use xrealloc; instead xfree and
21972 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21974 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21977 * gnutls.c: Renamed global_initialized to
21978 gnutls_global_initialized. Added internals for the
21979 :verify-hostname-error, :verify-error, and :verify-flags
21980 parameters of `gnutls-boot' and documented those parameters in the
21981 docstring. Start callback support.
21982 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21983 unless a fatal error occurred. Call gnutls_alert_send_appropriate
21984 on error. Return error code.
21985 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
21986 (emacs_gnutls_read): Likewise.
21987 (Fgnutls_boot): Return handshake error code.
21988 (emacs_gnutls_handle_error): New function.
21989 (wsaerror_to_errno): Likewise.

22055 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
22056 * doprnt.c: Include limits.h.
22057 (SIZE_MAX): New macro.
22058 (doprnt): Return a size_t value. 2nd arg is now size_t.
22059 Many local variables are now size_t instead of int or unsigned.
22060 Improve overflow protection. Support `l' modifier for integer
22061 conversions. Support %l conversion. Don't assume an EMACS_INT
22062 argument for integer conversions and for %c.
22064 * lisp.h (doprnt): Restore prototype.
22066 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
22067 $(SRC)/character.h.
22069 * Makefile.in (base_obj): Add back doprnt.o.
22071 * deps.mk (doprnt.o): Add back prerequisites.
22072 (callint.o): Depend on character.h.
22074 * eval.c (internal_lisp_condition_case): Include the handler
22075 representation in the error message.
22076 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
22077 when breaking from the loop.
22079 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
22081 * callint.c (Fcall_interactively): When displaying error message
22082 about invalid control letter, pass the character's codepoint, not
22083 a pointer to its multibyte form. Improve display of the character
22084 in octal and display also its hex code.
22086 * character.c (char_string): Use %x to display the (unsigned)
22087 codepoint of an invalid character, to avoid displaying a bogus
22090 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
22091 `error', not SYMBOL_NAME itself.
22093 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
22094 character arguments to `error'.
22096 * charset.c (check_iso_charset_parameter): Fix incorrect argument
22097 to `error' in error message about FINAL_CHAR argument. Make sure
22098 FINAL_CHAR is a character, and use %c when it is passed as
22099 argument to `error'.

22163 Define only if needed.
22165 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
22166 by pacifying GCC about it. Maybe it's time to retire it?
22167 * xfaces.c (USG, __TIMEVAL__): Likewise.
22169 * dispextern.h (struct redisplay_interface): Rename param
22170 to avoid shadowing.
22171 * termhooks.h (struct terminal): Likewise.
22172 * xterm.c (xembed_send_message): Likewise.
22174 * insdel.c (make_gap_smaller): Define only if

22312 * process.c (send_process): Adjust to the new signatures of
22313 emacs_write and emacs_gnutls_write. Do not attempt to store

22634 * ccl.h (check_ccl_update, Vccl_program_table): Remove decls.
22635 * ccl.c (Vccl_program_table): Now static.
22636 (check_ccl_update): Remove; unused.
22638 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
22639 * category.h: ... from here.
22640 * category.c (check_category_table, set_category_set): Now static.
22642 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
22643 * lisp.h: Remove these decls.
22645 * buffer.c (buffer_count): Remove unused var.
22647 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
22648 so that it's not optimized away.
22649 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
22650 * dispextern.h (bidi_dump_cached_states): Remove, since it's
22651 exported only to the debugger.
22653 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
22654 * atimer.h (run_all_atimers): Remove; not exported.
22656 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
22657 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
22658 was inaccessible from Lisp.
22659 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
22660 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
22662 alloc.c: Import and export fewer symbols, and remove unused items.
22663 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
22665 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
22666 it's not optimized away by whole-program optimization.
22667 (message_enable_multibyte, free_misc): Remove.
22668 (catchlist, handlerlist, mark_backtrace):
22669 Declare only if BYTE_MARK_STACK.
22670 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
22671 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
22672 (message_enable_multibyte): Remove decl.
22673 (free_misc, interval_free_list, float_block, float_block_index):
22674 (n_float_blocks, float_free_list, cons_block, cons_block_index):
22675 (cons_free_list, last_marked_index):
22677 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
22678 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
22679 (mark_backtrace): Define only if BYTE_MARK_STACK.
22680 * xdisp.c (message_enable_multibyte): Now static.
22682 Declare Lisp_Object Q* variables to be 'static' if not exported.
22683 This makes it easier for human readers (and static analyzers)
22684 to see whether these variables are used from other modules.
22685 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
22686 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
22687 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

22690 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
22691 * xmenu.c, xselect.c:
22692 Declare Q* vars static if they are not used in other modules.
22693 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
22694 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
22695 Remove decls of unexported vars.
22696 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
22698 * lisp.h (DEFINE_FUNC): Make sname 'static'.
22700 Make Emacs functions such as Fatom 'static' by default.
22701 This makes it easier for human readers (and static analyzers)
22702 to see whether these functions can be called from other modules.
22703 DEFUN now defines a static function. To make the function external
22704 so that it can be used in other C modules, use the new macro DEFUE.
22705 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
22706 (Finit_image_library):
22707 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
22708 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
22709 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
22710 Remove decls, since these functions are now static.
22711 (Funintern, Fget_internal_run_time): New decls, since these functions
22712 were already external.
22714 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
22715 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

22721 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
22722 Mark functions with DEFUE instead of DEFUN,
22723 if they are used in other modules.
22724 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
22725 decls for now-static functions.
22726 * buffer.h (Fdelete_overlay): Remove decl.
22727 * callproc.c (Fgetenv_internal): Mark as internal.
22728 * composite.c (Fremove_list_of_text_properties): Remove decl.

22732 * doc.c (Fdocumntation_property): New forward static decl.
22733 * eval.c (Ffetch_bytecode): New forward static decl.
22734 (Funintern): Remove extern decl; now in .h file where it belongs.
22735 * fileio.c (Fmake_symbolic_link): New forward static decl.
22736 * image.c (Finit_image_library): New forward static decl.
22737 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
22738 * intervals.h (Fprevious_property_change):
22739 (Fremove_list_of_text_properties): Remove decls.
22740 * keyboard.c (Fthis_command_keys): Remove decl.
22741 (Fcommand_execute): New forward static decl.
22742 * keymap.c (Flookup_key): New forward static decl.
22743 (Fcopy_keymap): Now static.
22744 * keymap.h (Flookup_key): Remove decl.
22745 * process.c (Fget_process): New forward static decl.
22746 (Fprocess_datagram_address): Mark as internal.

22757 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
22759 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
22762 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22764 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22765 when at ZV. (Bug#8487)
22767 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22769 * charset.c (Fclear_charset_maps): Use xfree instead of free.
22771 * keyboard.c (parse_tool_bar_item): Likewise.
22772 * sound.c (sound_cleanup, alsa_close): Likewise.
22773 * termcap.c (tgetent): Likewise.
22774 * xfns.c (x_default_font_parameter): Likewise.
22775 * xsettings.c (read_and_apply_settings): Likewise.
22777 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22778 (overrun_check_free): Protoize.
22780 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22782 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22783 since callers should never pass a negative size.
22784 Change the signature to match that of plain 'read' and 'write'; see
22785 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22786 * lisp.h: Update prototypes of emacs_write and emacs_read.
22788 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22790 * xdisp.c (redisplay_window): Don't try to determine the character
22791 position of the scroll margin if the window start point w->startp
22792 is outside the buffer's accessible region. (Bug#8468)
22794 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22796 Fix write-region and its subroutines for buffers > 2GB.
22797 * fileio.c (a_write, e_write): Modify declaration of arguments and
22798 local variables to support buffers larger than 2GB.
22799 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22801 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22802 argument, local variables, and return value.
22804 * lisp.h: Update prototypes of emacs_write and emacs_read.
22806 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22808 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22810 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22812 Fix more problems found by GCC 4.6.0's static checks.
22814 * xdisp.c (vmessage): Use a better test for character truncation.
22816 * charset.c (load_charset_map): <, not <=, for optimization,
22817 and to avoid potential problems with integer overflow.
22818 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22819 * casetab.c (set_identity, shuffle): Likewise.
22820 * editfns.c (Fformat): Likewise.
22821 * syntax.c (skip_chars): Likewise.
22823 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22824 This also lets GCC 4.6.0 generate slightly better loop code.
22826 * callint.c (Fcall_interactively): <, not <=, for optimization.
22827 (Fcall_interactively): Count the number of arguments produced,
22828 not the number of arguments given. This is simpler and lets GCC
22829 4.6.0 generate slightly better code.
22831 * ftfont.c: Distingish more carefully between FcChar8 and char.
22832 The previous code passed unsigned char * to a functions like
22833 strlen and xstrcasecmp that expect char *, which does not
22834 conform to the C standard.
22835 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22836 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22837 char * when the C standard requires it.
22839 * keyboard.c (read_char): Remove unused var.
22841 * eval.c: Port to Windows vsnprintf (Bug#8435).
22842 Include <limits.h>.
22843 (SIZE_MAX): Define if the headers do not.
22844 (verror): Do not give up if vsnprintf returns a negative count.
22845 Instead, grow the buffer. This ports to Windows vsnprintf, which
22846 does not conform to C99. Problem reported by Eli Zaretskii.
22847 Also, simplify the allocation scheme, by avoiding the need for
22848 calling realloc, and removing the ALLOCATED variable.
22850 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22852 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22853 But keep the doprint source code for now, as we might revamp it
22854 and use it again (Bug#8435).
22855 * lisp.h (doprnt): Remove.
22856 * Makefile.in (base_obj): Remove doprnt.o.
22857 * deps.mk (doprnt.o): Remove.
22859 error: Print 32- and 64-bit integers portably (Bug#8435).
22860 Without this change, on typical 64-bit hosts error ("...%d...", N)
22861 was used to print both 32- and 64-bit integers N, which relied on
22862 undefined behavior.
22863 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22864 * lisp.h (error, verror): Mark as printf-like functions.
22865 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22866 Report overflow in size calculations when allocating printf buffer.
22867 Do not truncate output string at its first null byte.
22868 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22869 Truncate the output at a character boundary, since vsnprintf does not
22871 * charset.c (check_iso_charset_parameter): Convert internal
22872 character to string before calling 'error', since %c now has the
22874 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22875 overflow when computing char to be passed to 'error'. Do not
22876 pass Lisp_Object to 'error'; pass the integer instead.
22877 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22878 formatted with plain %d.
22880 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22882 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22884 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22886 * xterm.c (x_catch_errors): Remove duplicate declaration.
22888 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22890 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22892 2011-04-10 Jim Meyering <meyering@redhat.com>
22894 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22895 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22896 return ssize_t not "int", and use size_t as the buffer length.
22897 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22898 * gnutls.h: Update declarations.
22899 * process.c (read_process_output): Use ssize_t, to match.
22900 (send_process): Likewise.
22902 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22904 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22906 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22908 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22909 Use unsigned char, to match FcChar8 type definition.
22911 * xterm.c (handle_one_xevent):
22912 * xmenu.c (create_and_show_popup_menu):
22913 * xselect.c (x_decline_selection_request)
22914 (x_reply_selection_request): Avoid type-punned deref of X events.
22916 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22918 Fix some uses of `int' instead of EMACS_INT.
22919 * search.c (string_match_1, fast_string_match)
22920 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22921 (scan_buffer, find_next_newline_no_quit)
22922 (find_before_next_newline, search_command, Freplace_match)
22923 (Fmatch_data): Make some `int' variables be EMACS_INT.
22925 * xdisp.c (display_count_lines): 3rd argument and return value now
22926 EMACS_INT. All callers changed.
22927 (pint2hrstr): Last argument is now EMACS_INT.
22929 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22930 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22931 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
22932 (decode_coding_utf_16, decode_coding_emacs_mule)
22933 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
22934 (decode_coding_ccl, decode_coding_charset)
22935 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
22936 (decode_coding_iso_2022, decode_coding_emacs_mule)
22937 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
22938 <char_offset, last_offset>: Declare EMACS_INT.

22940 (encode_coding_emacs_mule, encode_invocation_designation)
22941 (encode_designation_at_bol, encode_coding_iso_2022)
22942 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22943 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22945 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22946 (encode_invocation_designation): Last argument P_NCHARS is now
22948 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22949 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22951 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22954 * ccl.c (Fccl_execute_on_string): Declare some variables
22957 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22959 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22961 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22963 * process.c (Fformat_network_address): Doc fix.
22965 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22967 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22969 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22971 * keyboard.c (read_char): Call Lisp function help-form-show,
22972 instead of using internal_with_output_to_temp_buffer.
22973 (Qhelp_form_show): New var.
22974 (syms_of_keyboard): Use DEFSYM macro.
22976 * print.c (internal_with_output_to_temp_buffer): Function deleted.

22980 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
22982 * process.c (Flist_processes): Remove to Lisp.
22983 (list_processes_1): Delete.
22985 2011-04-06 Eli Zaretskii <eliz@gnu.org>
22987 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22989 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22991 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22993 Fix more problems found by GCC 4.6.0's static checks.
22995 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
22997 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22999 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
23001 * xdisp.c (vmessage): Mark as a printf-like function.
23003 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
23005 * sound.c (sound_warning): Don't crash if arg contains a printf format.
23007 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
23008 printf-like functions.
23009 (tiff_load): Add casts to remove these marks before passing them
23010 to system-supplied API.
23012 * eval.c (Fsignal): Remove excess argument to 'fatal'.
23014 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
23015 This avoids several warnings with gcc -Wstrict-overflow.
23016 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
23017 directly, rather than having caller test rule sign. This avoids
23018 some unnecessary tests.
23019 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
23020 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
23021 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
23023 * xfont.c (xfont_text_extents): Remove var that was set but not used.
23024 (xfont_open): Avoid unnecessary tests.
23026 * composite.c (composition_gstring_put_cache): Use unsigned integer.

23035 by using the new macro.
23037 * textprop.c (set_text_properties_1): Change while to do-while,
23038 since the condition is always true at first.
23040 * intervals.c (graft_intervals_into_buffer): Mark var as used.
23041 (interval_deletion_adjustment): Return unsigned value.
23044 * process.c (list_processes_1, create_pty, read_process_output):

23046 (create_pty): Remove unnecessary "volatile"s.
23047 (Fnetwork_interface_info): Avoid possibility of int overflow.
23048 (read_process_output): Do adaptive read buffering even if carryover.
23049 (read_process_output): Simplify nbytes computation if buffered.

23060 * print.c (print_error_message): Avoid int overflow.
23062 * font.c (font_list_entities): Redo for clarity,
23063 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

23078 (wordify): Omit three unnecessary tests.
23080 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

23085 * dired.c (file_name_completion): Remove var that is set but not used.
23087 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
23089 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
23090 (Finsert_file_contents): Remove unnecessary code checking fd.
23092 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
23093 Check for integer overflow on size calculations.
23095 * buffer.c (Fprevious_overlay_change): Remove var that is set
23098 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
23099 Remove vars that are set but not used.
23100 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
23101 (timer_check_2): Mark vars as initialized.
23103 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
23105 * image.c (lookup_image): Remove var that is set but not used.
23106 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
23108 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
23109 that are set but not used.
23111 * xfns.c (make_invisible_cursor): Don't return garbage
23112 if XCreateBitmapFromData fails (Bug#8410).
23114 * xselect.c (x_get_local_selection, x_handle_property_notify):
23115 Remove vars that are set but not used.
23117 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
23118 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
23120 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
23121 Remove var that is set but not used.
23122 (scroll_bar_windows_size): Now size_t, not int.
23123 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
23124 Check for overflow.
23126 * xfaces.c (realize_named_face): Remove vars that are set but not used.
23127 (map_tty_color) [!defined MSDOS]: Likewise.
23129 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
23131 * coding.c: Remove vars that are set but not used.
23132 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
23133 All callers changed.
23134 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
23135 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
23136 (decode_coding_charset): Remove vars that are set but not used.
23138 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
23139 that is set but not used.
23141 * print.c (print_object): Remove var that is set but not used.
23143 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
23144 The gnulib version avoids calling malloc in the usual case,
23145 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
23146 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
23147 * filelock.c (current_lock_owner): Likewise.
23148 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
23149 * sysdep.c: Include allocator.h, careadlinkat.h.
23150 (emacs_no_realloc_allocator): New static constant.
23151 (emacs_readlink): New function.
23152 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
23153 ../lib/careadlinkat.h.
23155 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
23157 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
23158 first non-nil return value).

23179 do not dereference NULL upon failed strdup
23180 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
23181 (ns_get_family): Likewise.
23183 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
23185 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
23187 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
23189 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
23192 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
23194 Add lexical binding.
23196 * window.c (Ftemp_output_buffer_show): New fun.
23197 (Fsave_window_excursion):
23198 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
23200 * lread.c (lisp_file_lexically_bound_p): New function.

23203 Bind Qinternal_interpreter_environment.
23204 (Feval_buffer): Bind Qlexical_binding.
23205 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
23207 (syms_of_lread): Declare `lexical-binding'.
23209 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
23211 * keyboard.c (eval_dyn): New fun.
23212 (menu_item_eval_property): Use it.
23214 * image.c (parse_image_spec): Use Ffunctionp.
23216 * fns.c (concat, mapcar1): Accept byte-code-functions.
23218 * eval.c (Fsetq): Handle lexical vars.
23219 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
23220 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
23221 (FletX, Flet): Obey lexical binding.
23222 (Fcommandp): Handle closures.
23223 (Feval): New `lexical' arg.
23224 (eval_sub): New function extracted from Feval. Use it almost
23225 everywhere where Feval was used. Look up vars in lexical env.
23227 (Ffunctionp): Move from subr.el.
23228 (Ffuncall): Handle closures.
23229 (apply_lambda): Remove `eval_flags'.
23230 (funcall_lambda): Handle closures and new byte-code-functions.
23231 (Fspecial_variable_p): New function.
23232 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
23233 but without exporting it to Lisp.
23235 * doc.c (Fdocumentation, store_function_docstring):
23236 * data.c (Finteractive_form): Handle closures.
23238 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
23241 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
23243 (exec_byte_code): New function extracted from Fbyte_code to handle new
23244 calling convention for byte-code-functions. Add new byte-codes.
23246 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
23248 * alloc.c (Fmake_symbol): Init new `declared_special' field.
23250 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
23252 * xdisp.c (redisplay_internal): Fix prototype.
23254 2011-03-31 Eli Zaretskii <eliz@gnu.org>
23256 * xdisp.c (SCROLL_LIMIT): New macro.
23257 (try_scrolling): Use it when setting scroll_limit.
23258 Limit scrolling to 100 screen lines.
23259 (redisplay_window): Even when falling back on "recentering",
23260 position point in the window according to scroll-conservatively,
23261 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
23263 (try_scrolling): When point is above the window, allow searching
23264 as far as scroll_max, or one screenful, to compute vertical
23265 distance from PT to the scroll margin position. This prevents
23266 try_scrolling from unnecessarily failing when
23267 scroll-conservatively is set to a value slightly larger than the
23268 window height. Clean up the case of PT below the margin at bottom
23269 of window: scroll_max can no longer be INT_MAX. When aggressive
23270 scrolling is in use, don't let point enter the opposite scroll
23271 margin as result of the scroll.
23272 (syms_of_xdisp) <scroll-conservatively>: Document the
23273 threshold of 100 lines for never-recentering scrolling.
23275 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
23277 * dispextern.h (move_it_by_lines):

23280 (message_log_check_duplicate): Remove parameters `prev_bol' and
23281 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
23282 (redisplay_internal): Remove parameter `preserve_echo_area',
23283 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
23285 * indent.c (Fvertical_motion):
23286 * window.c (window_scroll_pixel_based, Frecenter):
23287 Don't pass `need_y_p' to `move_it_by_lines'.
23289 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
23291 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
23292 steal a few bits to be more compact.
23293 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
23294 Remove unneeded casts.
23296 * bytecode.c (Fbyte_code): CAR and CDR can GC.
23298 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
23300 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
23301 binding" message (bug#7967).
23303 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
23305 Fix more problems found by GCC 4.6.0's static checks.
23307 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
23308 Remove unused local var.
23310 * editfns.c (Fmessage_box): Remove unused local var.
23312 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
23313 (note_mode_line_or_margin_highlight, note_mouse_highlight):
23314 Omit unused local vars.
23315 * window.c (shrink_windows): Omit unused local var.
23316 * menu.c (digest_single_submenu): Omit unused local var.
23317 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
23318 Omit unused local var.
23320 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
23321 Don't assume string length fits in int.
23322 (keyremap_step, read_key_sequence): Use size_t for sizes.
23323 (read_key_sequence): Don't check last_real_key_start redundantly.
23325 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
23326 instead of alloca (Bug#8344).
23328 * eval.c (Fbacktrace): Don't assume nargs fits in int.
23329 (Fbacktrace_frame): Don't assume nframes fits in int.
23331 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
23333 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
23336 * term.c (produce_glyphless_glyph): Remove unnecessary test.
23338 * cm.c (calccost): Turn while-do into do-while, for clarity.
23340 * keyboard.c (syms_of_keyboard): Use the same style as later
23341 in this function when indexing through an array. This also
23342 works around GCC bug 48267.
23344 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
23346 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
23348 * chartab.c (sub_char_table_ref_and_range): Redo for slight
23349 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
23351 * keyboard.c, keyboard.h (num_input_events): Now size_t.
23352 This avoids undefined behavior on integer overflow, and is a bit
23353 more convenient anyway since it is compared to a size_t variable.
23355 Variadic C functions now count arguments with size_t, not int.
23356 This avoids an unnecessary limitation on 64-bit machines, which
23357 caused (substring ...) to crash on large vectors (Bug#8344).

23367 * fns.c (concat): Likewise.
23368 * frame.c (x_set_frame_parameters): Likewise.
23369 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
23370 0 if not found, not -1. All callers changed.
23372 * alloc.c (garbage_collect): Don't assume stack size fits in int.
23373 (stack_copy_size): Now size_t, not int.
23374 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
23376 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
23378 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
23379 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
23380 All callers changed.
23382 * lisp.h (multibyte_char_to_unibyte):
23383 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
23384 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

23395 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
23396 don't set the hook to nil, but remove the offending function instead.
23397 (Qcommand_hook_internal): Remove, unused.
23398 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
23399 Vcommand_hook_internal.
23401 * eval.c (enum run_hooks_condition): Remove.
23402 (funcall_nil, funcall_not): New functions.
23403 (run_hook_with_args): Call each function through a `funcall' argument.

23417 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
23418 All callers changed.
23420 * w32.c (_wsa_errlist): Use braces for struct initializers.
23422 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

23475 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
23477 * keyboard.c (timer_check): Remove parameter `do_it_now',

23580 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
23582 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
23583 unconditionally since it does the check itself.
23585 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
23587 Fix more problems found by GCC 4.5.2's static checks.
23589 * coding.c (encode_coding_raw_text): Avoid unnecessary test
23590 the first time through the loop, since we know p0 < p1 then.
23591 This also avoids a gcc -Wstrict-overflow warning.
23593 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
23594 leading to a memory leak, possible in functions like
23595 load_charset_map_from_file that can allocate an unbounded number
23596 of objects (Bug#8318).
23598 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
23599 that could (at least in theory) be that large.
23601 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
23602 This is less likely to overflow, and avoids undefined behavior if
23603 overflow does occur. All callers changed. Use strtoul to scan
23604 for the unsigned long integer.
23605 (pint2hrstr): Simplify and tune code slightly.
23606 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

23616 * fileio.c (Fcopy_file): Report error if fchown or fchmod
23619 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
23621 * process.c (Fmake_network_process): Use socklen_t, not int,
23622 where POSIX says socklen_t is required in portable programs.
23623 This fixes a porting bug on hosts like 64-bit HP-UX, where
23624 socklen_t is wider than int (Bug#8277).
23625 (Fmake_network_process, server_accept_connection):
23626 (wait_reading_process_output, read_process_output):
23629 * process.c: Rename or move locals to avoid shadowing.

23639 Make tparam.h and terminfo.c consistent.
23640 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23641 Include tparam.h instead, since it declares them.
23642 * cm.h (PC): Remove extern decl; tparam.h now does this.
23643 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23644 * terminfo.c: Include tparam.h, to check interfaces.
23645 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23646 (tparam): Adjust signature to match interface in tparam.h;
23647 this removes some undefined behavior. Check that outstring and len
23648 are zero, which they always are with Emacs.
23649 * tparam.h (PC, BC, UP): New extern decls.
23651 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
23652 (xftfont_open): Rename locals to avoid shadowing.

23666 * composite.c (composition_compute_stop_pos): Rename local to
23668 (composition_reseat_it): Remove unused locals.
23669 (find_automatic_composition, composition_adjust_point): Likewise.
23670 (composition_update_it): Mark var as initialized.
23671 (find_automatic_composition): Mark vars as initialized,
23672 with a FIXME (Bug#8290).

23676 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
23677 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
23678 (BUF_DEC_POS): Be more systematic about renaming local temporaries
23679 to avoid shadowing.
23681 * textprop.c (property_change_between_p): Remove; unused.
23683 * intervals.c (interval_start_pos): Now static.
23685 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

23691 Fix pointer signedness.
23692 (alsa_choose_format): Remove unused local var.
23693 (wav_play): Initialize a variable to 0, to prevent undefined
23694 behavior (Bug#8278).
23696 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23698 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23700 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23701 clobbering (Bug#8298).
23702 * sysdep.c (sys_subshell): Likewise.
23703 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23705 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23706 This should get cleaned up, so that child_setup has the
23707 same signature on all platforms.
23709 * callproc.c (call_process_cleanup): Now static.
23710 (relocate_fd): Rename locals to avoid shadowing.
23712 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
23714 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
23715 not to be necessary, and produces flickering.
23717 2011-03-20 Glenn Morris <rgm@gnu.org>
23719 * config.in: Remove file.
23721 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
23723 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
23724 are now in src/globals.h.
23725 (syms_of_minibuf): Remove spurious & from previous change.

23735 * xfaces.c (Fx_load_color_file):
23736 Read color file from absolute filename (bug#8250).

23751 (sigchld_handler): Now static.
23753 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
23754 That way, the code declares only the vars that it needs.

23764 (CONSTANTLIM): Remove; unused.
23765 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
23766 Define only if needed.
23768 * unexelf.c (unexec): Name an expression,
23769 to avoid gcc -Wbad-function-cast warning.
23770 Use a different way to cause a compilation error if anyone uses
23771 n rather than nn, a way that does not involve shadowing.
23772 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
23774 * deps.mk (unexalpha.o): Remove; unused.
23776 New file unexec.h, the (simple) interface for unexec (Bug#8267).

23847 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
23850 * lisp.h (eassert): Check that the argument compiles, even if
23851 ENABLE_CHECKING is not defined.
23853 * data.c (Findirect_variable): Name an expression, to avoid
23854 gcc -Wbad-function-cast warning.

23866 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
23867 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
23869 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
23870 (GC_STRING_CHARS): Remove; not used.
23871 (Fmemory_limit): Cast sbrk's returned value to char *.

23881 to use the following functions instead of these macros.
23882 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23883 EMACS_INT, since callers assume the returned value fits in int.

23897 (RETALLOC_IF): Define only if needed.
23898 (WORDCHAR_P): Likewise. This one is never needed, but is used
23899 only in a comment talking about a compiler bug, so put inside
23900 the #if 0 of that comment.

23928 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23929 New macros, so that the caller can use some names other than
23930 gcpro1, gcpro2, etc.
23931 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23933 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23934 argument, for consistency with GCPRO2_VAR, etc: it is now the
23935 prefix of the variable, not the variable itself. All uses
23937 * dired.c (directory_files_internal, file_name_completion):
23938 Rename locals to avoid shadowing.
23940 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23941 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23942 dired.c's scmp function, had undefined behavior.
23943 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23944 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23945 * buffer.h: ... to here, because these macros use current_buffer,
23946 and the new implementation with inline functions needs to have
23947 current_buffer in scope now, rather than later when the macros
23949 (downcase, upcase1): New static inline functions.
23950 (DOWNCASE, UPCASE1): Reimplement using these functions.
23951 This avoids undefined behavior in expressions like
23952 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23953 from race conditions in accessing the global variables
23954 case_temp1 and case_temp2.

23992 * buffer.c (fix_overlays_before): Mark locals as initialized.
23993 (fix_start_end_in_overlays): Likewise. This function should be
23994 simplified by using pointers-to-pointers, but that's a different

24003 to suppress a gcc -Wclobbered warning that does not seem to be right.
24004 (MAXPATHLEN): Define only if needed.
24006 * process.c (serial_open, serial_configure): Move decls from here ...
24007 * systty.h: ... to here, so that they can be checked.
24009 * fns.c (get_random, seed_random): Move extern decls from here ...
24010 * lisp.h: ... to here, so that they can be checked.
24012 * sysdep.c (reset_io): Now static.

24020 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
24021 (describe_map_tree):
24022 Rename locals to avoid shadowing.
24024 * keyboard.c: Declare functions static if they are not used elsewhere.

24365 (decode_coding_emacs_mule): Mark variables that gcc
24366 -Wuninitialized does not deduce are never used uninitialized.
24367 (detect_coding_iso_2022): Initialize a local variable that might
24368 be used uninitialized. Leave a FIXME because it's not clear that
24369 this initialization is needed. (Bug#8211)
24370 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
24371 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):
